Abstract

A mannequin for supporting a pair of trousers whereon a laser marking is performed, having two leg structures housed inside the trouser legs. Each structure has a longitudinal axis, upper and lower areas, front and rear planes, an inner side and outer side. The separation between the inner and outer sides varies due to the tensing mechanism in order to go from a non-operative loosened position (A) to a maximum tensed end position (B) to perform the marking. Each leg structure is coupled to a respective main rotation axis around which rotates by a respective articulation having the mannequin for each leg structure. The main rotation axis is parallel to the direction of the dimension of the rise of the pair of trousers or collinear with it. The front planes can form at least two angles greater and/or less than 180° when rotated around the respective main rotation axes thereof.

DETAILED DESCRIPTION OF THE DRAWINGS

[0078] FIGS. 1, 2 and 6 to 10 show a mannequin 1 for supporting a pair of trousers (not shown) whereon a laser marking is performed in order to give certain areas thereof marks in order to give the pair of trousers a worn appearance.

[0079] The mannequin 1 comprises two leg structures 2 suitable to be housed on the inside of the legs of the trousers to be marked, which are commonly called semi-trouser holders. Each leg structure 2 is defined by a respective imaginary longitudinal axis 20 (see FIGS. 1 and 6) wherein the respective trouser leg of the pair of trousers to be assembled on the mannequin extends, an upper area 21 (which is closer to and above the waist of the pair of trousers), a lower area 22, a front plane 23 whereon the front portion of the trouser leg is arranged, a rear plane 24 whereon the rear portion of the trouser leg is arranged, an inner side 25 whereon the inner lateral edge of the pair of trousers is arranged, which goes from the joining of the trouser legs to the lower end of the respective trouser leg, and an outer side 26, opposite from the inner side 25, whereon the outer lateral edge of the pair of trousers is arranged, lateral edge which goes from the waist to the lower end of the trouser leg.

[0080] Each inner side 25 comprises a straight inner bar 25a which extends in a direction parallel to that of the imaginary longitudinal axis 20, and moreover, each outer side 26 comprises a straight outer bar 26a parallel to the inner bar 25a. Furthermore, for each leg structure 2 there is an intermediate bar 34 arranged parallel to and between the respective inner bar 25a and outer bar 26a. The inner bars 25a and the outer bars 26a are formed by bars or profiles having a front face and a rear face. The front faces of the inner 25 and outer 26 sides of a leg structure 2 are the ones which are taken into account in order to determine the front plane 23 of said leg structure 2, and the rear faces, opposite from the front ones, are the ones which determine the rear plane 24. The distance between the front plane 23 and the rear plane 24 translates into the thickness of the profiles or bars making up the inner 25 and outer 26 sides.

[0081] The mannequin 1 comprises a tensing mechanism 3 due to which the separation distance between the inner side 25 and the outer side 26 of each leg structure 2 is variable, such that each leg structure 2 can adopt and go from a non-operative loosened position A, shown in FIGS. 6 to 10, to a maximum tensed end position B, shown in FIGS. 1 and 2, wherein the separation distance between the inner side 25 and the outer side 26 of each leg structure 2 increases until it reaches the value corresponding to the dimension of the total width of the trouser leg, the front and rear portions of the trouser leg arranged on the leg structure 2 staying extended to the maximum in order to perform the laser marking on any of the portions. The tensing mechanism 3 does not comprise any chamber or inflatable balloon, but rather the pair of trousers on the mannequin 1 resembles, in the maximum tensed end position, how the pair of trousers would be if it were arranged flattened and stretched.

[0082] According to the represented embodiment of the mannequin 1 in FIGS. 1, 2 and 6 to 10, the inner side 25 comprises a plate with an inner profile 25b which defines an outline simulating the shape had by the inner lateral edge of the trouser leg which goes from the joining point of the trouser legs to the lower end of the respective trouser leg when the trouser leg is flattened with the front portion thereof and the rear portion thereof on top of each other. Moreover, the outer side 26 comprises a plate with an outer profile 26b which defines an outline simulating the shape had by the outer lateral edge of the trouser leg which goes from the waist to the lower end of the respective trouser leg when the trouser leg is flattened with the front portion thereof and the rear portion thereof on top of each other. The plates with inner 25b and outer 26b profiles, or most of them, are contained in a plane parallel to the front 23 and rear 24 planes of the respective leg structures 2 thereof. The plate with an outer profile 26b of each leg structure 2 is intended to come into contact with at least one portion of the outer lateral edge (or with all of the outer lateral edge) of the leg of the pair of trousers when the leg structure 2 is in the maximum tensed end position B, shown in FIGS. 1 and 2.

[0083] The plate with an inner profile 25b and the plate with an outer profile 26b have a thickness, measured in the direction perpendicular to the front plane 23 of the leg structure 2, comprised between 0.5 and 6 mm (around 1.5 mm in many of the plates). Nevertheless, in a plate with a profile, the thickness, instead of being constant, can vary in different areas of the plate, the thickness being lesser in the segment of the plate closer to the ends able to come into contact with the edges of the trouser legs. Preferably, they are made of metal, and more preferably, aluminium. It can be seen how the plate with an inner profile 25b has a width which varies along the inner side 25, being wider in the area of the outline simulating the shape had by the inner lateral edge of the trouser leg at the joining point of the trouser legs, and narrower at the upper and lower ends.

[0084] It can be clearly seen in FIGS. 1 and 2 that in the plate with an inner profile 25b, on the edge defining the outline, a rise appendix 9 is arranged indicated to stretch the area of the rise of the pair of trousers and so that no wrinkles are left, so that this area can be marked well with the laser. The rise appendix 9 has a vertex at the free end thereof (the one opposite from the end by which it is joined or coupled to the plate with an inner profile 25b). The rise appendix 9 can be oriented, according to the design or model of the pair of trousers to be marked, according to an appendix plane which is parallel, perpendicular or which forms a certain oblique angle with the plate with an inner profile 25b of the respective leg structure 2, according to the model of trouser to be loaded and marked. In FIGS. 1 and 2, the rise appendix 9 forms an oblique angle although it is close to 90°. FIG. 5 partially shows leg structures 2 with other embodiment of plates with inner 25b and outer 26b profiles, being able to show in detail the arrangement of the rise appendix 9 with respect to the plane wherein most of the plate with an inner profile 25b is contained.

[0085] The plates with an inner profile 25b are detachably joined (for example, by a joint screwed at one or more points, by a joint pivotable at one point) to the respective inner bars 25a, and the same thing occurs with the plates with an outer profile 26b, which can be detachably joined to the outer bars 26a, thereby being able to disassemble the plates with inner 25b and outer 26b profiles from the respective inner 25a and outer 26a bars, and be replaced by other plates with inner 25b and outer 26b profiles in accordance with another trouser design with a different shape of the lateral edges of the trouser legs. Thus, the plates with inner and outer profiles 25b and 26b can be changed, for example, by screwing them and unscrewing them from the inner and outer bars 25a and 26a, according to the model and size of the trousers to be marked.

[0086] FIG. 11 also shows that each outer side 26 is provided in an area close to the upper end thereof with a stop 30 in an upside-down L shape wherein the waist of the pair of trousers is placed. In the maximum tensed end position B, the pair of trousers will be completely tensed. It also shows that the plate with an outer profile 26b comes just after the lower end of the stop 30, since normally it starts from the waist downwards when the trousers have an increase in the width thereof in order to make room for the hips. Each model of trouser and size varies the hip and leg width thereof along the length thereof, hence the plate with an outer profile 26b reaches the area of the edge of the outermost side of the pair of trousers.

[0087] The mannequin 1 stands out in that the two leg structures 2 are coupled in an articulated manner to a respective main rotation axis 5 around which each leg structure 2 is able to rotate by means of a respective articulation 51 comprised by the mannequin 1 for each leg structure, the main rotation axis 5 being an axis parallel with the direction of the dimension of the rise of the pair of trousers. It is recalled that rise of the pair of trousers is understood as the distance from the joining of the trouser legs (a point located underneath what corresponds to the fly of the pair of trousers if it has one) of a pair of trousers to the waist. Each leg structure 2 is able to rotate independently from the other leg structure 2, meaning, the rotation of one leg structure 2 does not have to influence the magnitude of rotation of the other leg structure 2, although in the preferred embodiment shown, the two leg structures 2 rotate the same magnitude of rotation and in the same direction of rotation.

[0088] FIGS. 1 and 2, 6 and 7, and 8 to 10 show the mannequin 1 in different positions wherein the two leg structures 2 have rotated around the respective main rotation axes 5 thereof (a vertical axis in the positions shown), for which reason the front planes 23 form between each other angles larger and smaller than 180°, for example, an angle comprised between 10° and 350°, and therefore, the two rear planes 24, opposite from the front planes 23, form between each other different angles comprised between 350° and 10° (the difference from subtracting from 360° the angle formed by the front planes 23). Angles can even be formed that are practically 0° and 360° when the two leg structures 2 are practically on top of each other (FIGS. 8 to 10).

[0089] This ability to rotate each leg structure 2 with respect to the main rotation axis 5 thereof enables the mannequin 1 to adopt multiple positions wherein to suitably expose practically any area of the pair of trousers to the effects of the laser, without there being portions of the mannequin 1 which are hidden or impede the laser beam from reaching the desired area, although most times the laser marking is done when the angle is 180°. This ability to rotate is also particularly advantageous for adopting the position like the one shown in FIGS. 8 to 10, since it is a position which enables the pair of trousers to be assembled onto the mannequin by introducing it folded in half (folded along the axis that would mark the rise of the pair of trousers), and thus it is no longer necessary for the operators to need to have the pair of trousers extended with their hands. Once the pair of trousers has been introduced from the bottom, the operator, manually or by means of the actuation of one or two motors, will have the mannequin 1 in a position wherein the front planes 23 form an angle between them of 180° and will then be able to activate the tensing of the trouser legs by means of the tensing mechanism 3 by which the separation distance between the inner side 25 and the outer side 26 increases in order to go from a non-operative loosened position A to the maximum tensed end position B of FIG. 1.

[0090] In order to perform the rotation of each leg structure 2 around the respective main rotation axis 5 thereof, each leg structure 2 comprises in the upper area 21 thereof a support 27 attached to transmission means 29 through which the rotation is imparted to the leg structure 2. The transmission means can in turn be coupled to motor means through which the independent rotation of each leg structure 2 is imparted. Each support 27 comprises two opposite main faces parallel respectively to the front plane 23 and the rear plane 24 defined in each leg structure.

[0091] The motor means of each leg structure, if they are had due to not being manual, can be formed by a servomotor for adjusting with precision the desired angle between the two front planes 23 (and therefore the angle between the two rear planes 24) and for a better control of the torque applied. The transmission means can be formed by straps and/or gears and thereby be the ones responsible for transmitting the torque generated by the servomotors to the supports 27 so that they are arranged forming between each other the optimal angles for the best exposure to the laser of the portion of a leg of the pair of trousers to be marked, without the other trouser leg interfering or creating hidden areas which impede the projected marking.

[0092] Nevertheless, according to the preferred embodiment, the two leg structures 2 rotate at the same time and the same angle, and the rotation can be imparted manually, without needing motor means. The transmission means of FIG. 4 makes the two supports 27 rotate at the same time and symmetrically with respect to the apical axial body 50 located in the upper end of the mannequin 1 when the user applies a force on one of the two supports 27. The representations of the mannequin 1 show the arrangement, above the upper areas 21 of the leg structures 2, of the cylindrical apical axial body 50 (it can also be prismatic) which extends in a direction parallel to the direction of the main rotation axes 5 of the leg structures 2. The apical axial body 50 is arranged equidistant from the two leg structures 2 and is integrally joined to a body supporting the articulations 51 by which each leg structure 2 can rotate around the respective main rotation axis 5 thereof. All of this is configured such that when the leg structures 2 rotate around the respective main rotation axes 5 thereof, they move with respect to the apical axial body 50.

[0093] Returning to the tensing mechanism 3 by which the mannequin 1 goes from position A to position B, said tensing mechanism 3 comprises actuation means shown in the partial cross sections of FIGS. 3, 4 and 11 formed by the following elements: a lever handle 40 so that the operator moves it downwards in order to start the tensing, the connecting rod 41 which rotates around shaft 46 when the lever 40 is pressed, the part 42 in an upside-down L provided with teeth on the lower arched end thereof which meshes with a pinion integral with the wheel 43 which when it rotates in the clockwise direction makes the wheel 43 rotate in the anti-clockwise direction and the guide 44 is moved towards the outside, dragging the outer side 26 and at the same time the intermediate bar 34 linked by the joining element 45. Thus, these actuation means impart the movement of the outer bar 26a and the intermediate bar 34 with respect to the inner bar 25a, increasing the separation distance between them when going from the non-operative loosened position A to the maximum tensed end position B, and decreasing the separation distance when going from the maximum tensed end position B to the non-operative loosened position A when the lever 40 is pushed upwards. Each support 27, which supports the inner bar 25a, the outer bar 26a and the intermediate bar 34 of each leg structure 2, preferably comprises on the inside thereof a guide for the movement of the corresponding outer bar 26a of the outer side 26 in accordance with a trajectory perpendicular to the longitudinal direction wherein the outer bar 26a extends.

[0094] The tensing mechanism 3 further comprises, for each leg structure 2, an intermediate bar 34 arranged parallel between the respective inner 25 and outer 26 sides, and practically coplanar with them, and that increases the separation distance with respect to the inner 25 and outer 26 sides when going from the non-operative loosened position A to the maximum tensed end position B, and decreases the separation distance when going from the maximum tensed end position B to the non-operative loosened position A. In fact, preferably and as seen in FIG. 1, the intermediate bar 34 is slightly thinner than the inner 25a and outer 26a bars. Advantageously, said inner 25a and outer 26a bars can have a respective inner space made which enables the intermediate bar 34 to be housed on the inside thereof when the leg structure 2 is in the non-operative loosened position A.

[0095] FIGS. 1 and 2 show how each intermediate bar 34 is joined to the inner 25 and outer 26 sides respectively by means of two connecting rods 35 articulated on the two ends thereof and parallel to each other, and by means of two connecting rods 36 articulated on the two ends thereof and parallel to each other. The outer side 26 and the intermediate bar 34 of each leg structure 2 are arranged such that they are movable with respect to the inner side 25, moving away from the inner side or moving towards the inner side 25 when going from the non-operative loosened position A to the maximum tensed end position B, and vice versa.

[0096] FIGS. 1 to 4 show that the support 27 of each leg structure 2 wherein the inner side 25 and the outer side 26 are supported, comprises a first semisupport 81 wherein the inner side 25 and the outer side 26 are supported, and a second semisupport 82 by which the leg structure 2 is joined in an articulated manner to a respective articulation 51 by which the leg structure 2 is able to rotate around the respective main rotation axis 5. The first semisupport 81 and the second semisupport 82 are joined in an articulated manner to each other, the first one with the ability to rotate with respect to the second one around an articulation for angular adjustment 80 between the trouser legs (there are trouser legs which form between each other an angle that is more open or more closed according to the model and size of trousers) with the ability to rotate around an angular adjustment axis. The angular adjustment axis is an axis perpendicular to the front plane 23 or perpendicular to the plane wherein the inner side 25 and the outer side 26 of the leg structure 2 are contained. The first semisupport 81 and the second semisupport 82 are configured articulated to each other by the articulation for angular adjustment 80 such that when the first one rotates with respect to the second one, the inner side 25 of the leg structure 2 varies the angle it forms with respect to the direction wherein the main rotation axis 5 extends which is parallel to the dimension of the rise of the pair of trousers or collinear with said direction. Thus, the mannequin 1 can vary the angle formed by the inner sides 25 of the two leg structures 2 with each other, as can be compared in FIGS. 1 and 2, in order to adjust the mannequin 1 to the model of trouser.

[0097] The first semisupport 81 and the second semisupport 82 of each leg structure 2 are formed by respective bodies each provided with a front plate and a rear plate, parallel to the front plane 23 and to the rear plane 24 of the leg structure 2, said plates being provided with holes, pivots and slots in order to carry out the rotation of the first semisupport 81 with respect to the second semisupport 82. Each leg structure 2 comprises an angle regulation mechanism to vary the angle formed by the inner sides 25 of the two leg structures 2 with each other or the angle formed by the inner bars 25a of the inner sides 25 of the two leg structures 2 with each other, and locking means 88 for the angle between the first semisupport 81 and the second semisupport 82.

[0098] The angle regulation mechanism comprises a spindle 84 arranged coupled in a fixed manner in the second semisupport 82 with respect to which it moves in a direction towards the first semisupport 81, provided with a head 83 able to be rotated manually in order to advance or withdraw the spindle 84, wherein the end of the spindle 84 is introduced into the first semisupport 81. The mechanism also comprises a nut 85 crossed through by the spindle 84, said nut 85 being provided with a pivot 86 arranged in a direction parallel to the angular adjustment axis. The pivot 86 is in turn arranged inside at least one slot 87 made in one of the front or rear plates of the first semisupport 81. All of this is arranged such that when the spindle 84 is rotated in an advance direction, the nut 85 moves with respect to the second semisupport 82 and the pivot 86 thereof exerts a pushing force inside the slot 87 of the first semisupport 81, making the slot 87 and the plate wherein it is located rotate with respect to the second semisupport 82 around the angular adjustment axis.

[0099] The locking means 88 for the angle (see FIG. 11) between the first semisupport 81 and the second semisupport 82 comprise an angle locking bolt 89b which is parallel to the direction of the angular adjustment axis, provided at one end with a head and at the other with a tightening nut or wing nut, the angle locking bolt 89b making up part of the second semisupport 82, and a slot in the shape of a circular arch provided in a plate 89a integrally joined to the first semisupport 81. The slot is crossed through by the angle locking bolt 89, the head staying on one side of the slot and the tightening nut or wing nut on the other side of the slot and protruding out of one of the front or rear plates of the second semisupport 82. When the locking nut or wing nut is tightened, it is tightened against the plate 89a, the head of the angle locking bolt 89a is tightened against the slot and the rotation between the first semisupport 81 and the second semisupport 82 is immobilised.

[0100] FIGS. 12 and 13 show an assembly formed by a mannequin 1 (another embodiment in these figures, although it could be the embodiment of FIG. 1) and a transportation cart 71 (see also the cart 71 of FIGS. 18 and 20). The transportation cart 71 is provided with movement motor means 74 (preferably, the cart 71 is actuated by means of electrical actuators) for the autonomous movement of the transportation cart 71 along a guided trajectory. The transportation cart 71 can be coupled to the mannequin 1 for the joint transportation thereof along a guided trajectory, wherein said coupling to the mannequin 1 is configured to enable access to the apical axial body 50 from the outside of the movement cart 71 and to enable the rotation of the mannequin 1 independently from the cart 71 around a vertical rotation axis of the mannequin 105 which coincides with the imaginary axial axis of the apical axial body 50 of the mannequin 1 when the apical axial body 50 is arranged in a vertical position.

[0101] According to the embodiment of the assembly shown in FIGS. 12 and 13, the transportation cart 71 is joined in an articulated manner to the mannequin 1 through a loading rotation axis 72 which is horizontal and perpendicular to the direction of the imaginary axial axis of the apical axial body 50 of the mannequin 1, the mannequin 1 being able to rotate around said loading rotation axis 72 and able to adopt a special loading position C for trousers. In this special loading position C, the front planes 23 or the rear planes 24 of the two leg structures 2 of the mannequin 1 are arranged forming an acute angle or arranged on top of each other, are contained in non-vertical planes and the imaginary axial axis of the apical axial body 50 of the mannequin 1 forms an acute angle with respect to the vertical direction, being able in said special loading position C to load onto the mannequin 1 a pair of trousers folded on itself along the line defining the rise thereof.

[0102] FIGS. 14 and 15 show a machine 10 for loading and exposing trousers to a laser for the marking thereof, comprising more than one loading area 11 wherein the loading of a pair of trousers onto a mannequin 1 is performed, and a marking area 12 wherein the pair of trousers loaded onto the mannequin 1 coming from one of the loading areas 11 is exposed to the external effects of a laser for the marking thereof. Said figures also schematically show a transmitter apparatus 100 of at least one laser beam directed towards the marking area 12 of the machine. The mannequin 1 of the loading area 11 and of the marking area 12 is a mannequin 1 which makes up part of a mannequin 1 and transportation cart 71 assembly described previously, in other words, with a mannequin 1 like the one of FIG. 1 and wherein the transportation cart 71 is movable through the movement motor means 74 along at least one guided trajectory for transportation 110 of the mannequin 1 from a loading area 11 to the marking area 12 and from the marking area 12 to the loading area 11. In these embodiments of the machine, it is not necessary for the mannequin 1 to be able to rotate with respect to the cart 71 around a loading rotation axis 72 like the one shown in FIGS. 12 and 13, since the loading of the folded pair of trousers can be performed by arranging the mannequin in the folded position of FIGS. 8 to 10.

[0103] Thus, FIGS. 14 and 15 show that the machine 10 for loading and exposing trousers to a laser for the marking thereof comprises more than one loading area 11, two loading areas 11 in FIG. 14 and four loading areas 11 in FIG. 15, separated from each other, and respective guided trajectories for transportation 110 which converge in one same marking area 12, wherein the machine 10 comprises at least one mannequin 1 and cart 71 assembly for each loading area 11. The guided trajectories for transportation 110 are trajectories arranged radially with respect to the marking area 12 located on one side (FIG. 14) or on both sides (FIG. 15) of the marking area 12, the marking area 12 facing a laser transmitter apparatus 100.

[0104] Thus, in the machine 10 of FIG. 14, wherein there are two loading areas 11 and two guided trajectories for transportation 110 converging towards a single marking area 12, two operators can work in order to increase productivity, and in the machine 10 of FIG. 15 with four loading areas 11, four operators can work.

[0105] According to other embodiments not shown, in the machines 10 of FIGS. 14 and 15 another transmitter apparatus 100 of at least one laser beam can be arranged opposite from the other apparatus on the other side of the marking area 12, in order to mark at the same time the opposite side of the pair of trousers which is being marked by the first transmitter apparatus 100.

[0106] FIGS. 16 to 20 show that the marking area 12 comprises a motorised (see motor 121) rotating positioning device 120 with the ability to rotate around a vertical positioning axis 123, located after, but separated from, the guided trajectories for transportation 110 by which the mannequins 1 are led by the transportation carts 71 from the loading areas 11 to the end of the guided trajectories for transportation 110. The positioning device 120 comprises a positioning rail 122 with a straight trajectory able to be aligned, when rotated with respect to the vertical positioning axis 123, with any of the guided trajectories for transportation 110 in order to receive in the marking area 12 the mannequin 1 led by the transportation cart 71. The positioning device 120 comprises connection means 124 (see FIGS. 18 and 20) able to connect to the apical axial body 50 of the mannequin 1 received in the positioning rail 122 and cause the rotation of the mannequin 1 around the imaginary axial axis of the apical axial body 50 of the mannequin 1, when said imaginary axis is parallel to the vertical direction.

[0107] Although it is not shown in the figures, the machine 10 comprises a control device for detecting the presence of persons in any of the loading area or areas 11, configured to send a warning signal to the movement motor means 74 of the transportation carts 71 by which the advance speed of the transportation carts 71 is controlled and varied in the guided trajectories for transportation 110, even being able to detect the advance thereof in any of the directions from the loading area or areas 11 to the marking area 12 and vice versa.

[0108] Thus, if an operator is close to a loading area 11 or the corresponding guided trajectory for transportation 110 thereof, the mannequin 1 which is already loaded will be transported slowly by the transportation cart 71 to the marking area 12, or for the case in which the pair of trousers loaded onto a mannequin 1 has already been marked and is transported from the marking area 12 to one of the loading areas 11 and the presence of an operator is detected, the mannequin 1 will also be transported slowly. Otherwise, when in the vicinity of a loading area 11 or of the guided trajectory for transportation 110 thereof, the presence of a person is not detected, the mannequins 1 loaded with trousers will be transported quickly to the marking area 12, and the same thing will occur when the pair of trousers has already been marked and needs to be transported to one of the loading areas 11 in order to unload it.

[0109] In the machines 10, the pairs of trousers loaded onto the mannequins 1 stay perfectly flat and enable a marking as if it were made on a table, with the difference that on this occasion the pair of trousers is in a vertical plane. The guided trajectories for transportation 110 and the trajectory within the loading area defined by the positioning rail 122 with a straight trajectory are only aligned when the loaded mannequin must go to the marking area 12 or must leave the marking area 12 in order to unload the pair of trousers; the rest of the time, during the marking, they stay unaligned. Furthermore, as seen in the figures, the positioning device 120 is independent from the loading areas 11 and from the guided trajectories for transportation 110 in order to prevent the transmission of vibrations. Results carried out by a machine 10 like those of FIGS. 14 and 15 have demonstrated that they are able to achieve the transfer of the mannequin 1 in 1.3 seconds from the loading area 11 to the marking area 12, in comparison to the 3.5 seconds of other conventional machines.

[0110] FIG. 21 shows a system made up of a machine 10 for loading and exposing trousers to a laser for the marking thereof, and an auxiliary device for the automatic loading and/or unloading 90 of trousers (further shown in FIG. 22). Said figures also show a transmitter apparatus 100 of at least one laser beam directed towards the marking area 12 of the machine 10. In the embodiment of the machine 10 shown in FIG. 21 and in FIG. 14, there are basically two areas, a loading area 11, wherein the loading of a pair of trousers onto a mannequin 1 is carried out, and a marking area 12, on the side opposite from the loading area 11. In the marking area 12, wherein the mannequin 1 which is already in the maximum tensed end position B, acquired in the loading area 11 once the pair of trousers was placed, adopts different positions in order to expose certain areas of the trousers which must be marked with the laser. As explained previously, the mannequin 1 is able to not only rotate around itself, for example around the main rotation axis 5, but that each leg structure 2 can be able (although it is not the preferred embodiment) to rotate independently of the other leg structure 2 around the main rotation axis 5 thereof and thus adopt positions which enable it, for example, to make a trouser leg covering the front plane 23 of one of the leg structures 2 face the laser, in order to receive the laser treatment, while the other trouser leg covering the front plane 23 of the other leg structure 2 stays behind forming a certain angle, staying out of reach of the laser. If at a certain moment the marking of the rear portion of one of the trouser legs must be performed, the mannequin 1 will once cause the rotation of the two leg structures 2 thereof in order to orient the rear plane 24 covering said rear portion towards the transmitter apparatus 100, being exposed to the laser beam which is projected. For time-saving reasons, the machine 10 shown in FIG. 21, instead of having one single mannequin 1 which is moved from the loading area 11 to the marking area 12, comprises at least two mannequins 1, one in each area, because while the loading of one pair of trousers onto a mannequin 1 is performed, another previously-loaded mannequin 1 can be in the marking area 12 receiving the laser treatment in the pair of trousers it carries. Once the laser treatment on the pair of trousers has ended, the mannequin 1 of the marking area 12 returns to the loading area 11 wherein the pair of trousers already having the desired worn appearance will be removed and a new pair of trousers will then be loaded.

[0111] In the machine 10 of FIG. 21, the mannequins 1 are assembled in respective motorised transportation carts 71 (see also the motor means 74 formed by a motor, reducer and pinion in FIG. 13) movable along zippers 70 and guides or rails, for transporting the mannequins 1 from the loading area 11 to the marking area 12, and vice versa. The mannequins 1 shown in FIG. 13 are mounted in an articulated manner on the transportation carts 71 in accordance with a horizontal loading rotation axis 72, perpendicular to the main rotation axis 5 (in this case common to the two leg structures 2), around which the mannequins 1 can rotate or tilt. Thus, the mannequins 1 are able to adopt a special loading position C wherein the trousers can be loaded onto the mannequins 1, the front planes 23 of the two leg structures 2 of a mannequin 1 being arranged forming an acute angle, for example about 20°, and said front planes 23 being contained in a non-vertical plane with respect to the support base of the machine 1 (it is implied that the machine 1 rests on the horizontal plane of the floor or pavement whereon it sits). The fact that a mannequin 1 can adopt the special loading position C described can be given, for example, by a cam with a certain profile (not shown in the drawings), joined to a certain segment of the guide or rail of the loading area 11, which forces the mannequin 1 as it moves, and through projecting bearings which make up the mannequin 1 located close to and underneath the transportation cart 71, to follow said cam profile designed so that the main rotation axis 5 rotates around the loading rotation axis 72 forming an acute angle with the vertical direction v, between 35° and 55°, preferably 45° and maintains said formation in that segment.

[0112] Due to this configuration able to rotate around the loading rotation axis 72, the mannequins 1 can adopt a special loading position C which is very comfortable for the operator, wherein the trousers can be loaded onto a mannequin 1 folded around the rise of the pair of trousers, with the trouser legs almost or practically on top of each other (which we do when folding a pair of trousers lengthwise, around the axis of symmetry of the pair of trousers), by being able to arrange the front planes 23 of the two leg structures 2 of a mannequin by forming a small acute angle of about 20° for example, according to the capacity thereof to rotate around the main rotation axis 5. Furthermore, by the mannequin 1 being able to tilt around the loading rotation axis 72, horizontal and perpendicular to the main rotation axis 5 of the mannequin 1, the mannequin 1 can be arranged with the front 23 and rear 24 planes of the leg structures 2 thereof in inclined planes, not vertical ones and the lower ends of the leg structures 2 from whence the mannequin 1 is dressed with the pair of trousers, are higher and are further forwards than the rest of the mannequin 1, for which reason the operator loading the mannequin 1 does not have to bend over in order to introduce the pair of trousers.

[0113] In this manner, the operator does not have to load the pair of trousers in the habitual position thereof, with the waist extended and bending over in order to pass underneath the pair of trousers, but rather the mannequin 1 can be arranged in the special loading position C thereof, with the front planes 23 forming an acute angle and in a position wherein said planes are inclined with respect to the vertical plane v, being able to load the pair of trousers folded along and from a height comfortable for arranging the lower portion of the mannequin 1 at the height of their hands when the operator is standing.

[0114] It is also envisaged that in the marking area 12, descending forced ventilation means (not shown in the drawings) are provided for the extraction through the lower portion of the machine 10 of the gases originating from the laser heating the inks of the pair of trousers during the marking.

[0115] FIGS. 21 and 22 show that facing the loading area 11 of the machine 10 an auxiliary device is arranged for loading and/or unloading 90 able to automatically perform the loading of a pair of trousers folded lengthwise over the mannequin 1 arranged in the special loading position C.

[0116] The auxiliary device for loading and/or unloading 90 comprises a plurality of waiting supports 9, 9′, made up of pairs of oblong waiting profiles 9a and 9b, arranged radially and inclined in a descending direction towards the centre, as if they were the petals of a flower. The waiting profiles 9a and 9b of one same pair are parallel to each other, are separated by a short distance and have a length such that they receive the insertion of the two legs of a pair of trousers in the position folded around the rise line of the pair of trousers. By way of example, a waiting support 9 or 9′ can be configured as a U-shaped fork, the arms of which are the waiting profiles 9a and 9b. Precisely the short distance separating the waiting profiles 9a and 9b is so that there is a space to place the two inner faces of the trouser legs which stay facing each other when the pair of trousers is folded.

[0117] The auxiliary device for loading and/or unloading 90 also comprises an introducing arm 91 made up of an inclined guide rail facing one of the waiting supports 9′ of the plurality of supports 9. The introducing arm 91 is arranged above said waiting support 9′, the length of the guide rail being such that it protrudes above the cited waiting support 9′, the upper end thereof being located at the same level or a higher level wherein the upper areas 21 of the leg structures 2 of the mannequin 1 located in the loading area 11 are located. The introducing arm 91 is provided with pushing projection means 92 slidable along the guide rail and which protrude, with respect to the guide rail towards the waiting support 9′, a distance such that the pushing projection means 92 are able to push a pair of trousers arranged folded over the waiting support 9′ and move it along the guide rail to the upper end thereof.

[0118] FIGS. 21 and 22 likewise show that the auxiliary device for loading and/or unloading 90 trousers shown comprises rotating means by which the plurality of waiting supports 9, 9′ are able to rotate with respect to a vertical central axis 94 aligned with the centre of the radial arrangement thereof, coaxial with the cylindrical casing 93 to which the introducing arm 91 is joined. The pushing projection means 92 of the introducing arm 91 protrude from the guide rail in the separation space between the two waiting profiles of the waiting support 9′ it is facing.

[0119] In order to make use of the auxiliary device for loading and/or unloading 90 to automatically load a pair of trousers on the mannequin 1, the first thing is to arrange a waiting support 9′ wherein a folded pair of trousers is supported and that this waiting support 9′ is facing the introducing arm 91. A mannequin 1 free of trousers must also be placed, in the loading position C in order to receive a folded pair of trousers activating the suitable means, arranging the front planes 23 of the leg structures 2 in non-vertical planes, and specifically, with the same inclination of the introducing arm 91. The two lower areas 22 of the leg structures 2 of the mannequin 1 will be arranged after the respective waiting profiles 9a and 9b which make up the waiting support 9′, aligned with them. The pushing projection means 92 will start the ascension thereof and will push the folded pair of trousers carrying it upwards by the joining area of the trouser legs. As the pair of trousers is dragged upwards, the pair of trousers will start to leave the waiting support 9′ and will enter the leg structures 2 of the mannequin 1 until the mannequin 1 of the loading area 11 is dressed. Afterwards, when the transfer of the mannequin 1 together with the transportation cart 71 thereof is activated, and passes along the cam profile located in an area of the rail, the lower areas 22 of the leg structures 2 will lower bit by bit and the mannequin 1 will be arranged with the front planes 23 in vertical planes and will be transported to the marking area 12.

[0120] Alternatively or additionally, the pushing projection means 92 can be provided with gripping elements such as for example clamps, which grip the waist of the pair of trousers by two segments and in this manner by sliding along the introducing arm carry the pair of trousers to the upper areas 21 of the leg structures and once there they release it so that the pair of trousers goes to the maximum tensed end position B.

[0121] It is also envisaged that the already-marked trousers can be unloaded in the same auxiliary device for loading and/or unloading 90 in the free waiting supports 9. An operator can be monitoring the automatic loading and also assisting the unloading of the trousers in the waiting supports 9. In this manner the auxiliary device for loading and/or unloading 90 is taken advantage of, the yield of the operator operating the automatic loading is optimised so that they also take care of the unloading, and the plant floor is optimised using a single auxiliary device for loading and/or unloading 90 also as an unloader. Another option would be to unload the marked trousers in a second auxiliary device for loading and/or unloading 90 exclusively dedicated to receiving marked trousers.

[0122] Alternatively to the flower configuration of the auxiliary device for loading and/or unloading 90 of the drawings, according to other embodiments the waiting supports 9 could adopt a roundabout-type configuration or more fanciful shapes but which likewise enable the different work steps or stations to be established: the manual loading of the trousers in the auxiliary device for loading and/or unloading 90, the automatic loading of the trousers from the auxiliary device for loading and/or unloading 90 to the mannequin 1 and vice versa, and the unloading of the already-marked trousers, manually or automatically, from the auxiliary device for automatic loading and/or unloading 90. Thus, the waiting supports 9 and 9′ are arranged inclined and cantilevered, they have the upper ends thereof free and the lower ends thereof are coupled to movement means by which the waiting supports 9, 9′ are movable with respect to the support base and in a guided manner according to a trajectory which can have any shape, while it goes underneath the introducing arm 91. In the movement thereof along said trajectory, a moment will arrive in which each of the waiting supports 9 goes underneath the introducing arm 91, becoming the waiting support 9′ upon reaching that point of the trajectory. In that point the inclination of said waiting support 9′ will be arranged parallel to the inclination of the introducing arm 91 and the pushing projection means 92 will protrude from the guide rail in the separation space between the two waiting profiles of the waiting support 9′ located beneath it.

[0123] Finally, apart from the distribution shown in FIGS. 21 and 22, it envisages arranging two automatic auxiliary devices for unloading and/or unloading 90 trousers in a plant, two machines 10 arranged side by side for loading and exposing trousers to a laser for the marking thereof and a single laser transmitter apparatus 100 for the marking thereof. In this manner the laser transmitter apparatus 100 works with a higher yield since it is the most expensive element of the three, for which reason it is suggested that it be stopped as little time as possible.

[0124] Thus, it is clear that the auxiliary devices for loading and/or unloading 90 can be used not only for loading trousers but also for unloading. A machine 10 can be attached to an auxiliary device for loading and/or unloading 90 full of folded trousers in the waiting supports 9, from which the mannequins 1 of the loading area 11 are loaded, and another empty auxiliary device for loading and/or unloading 90, in an unloading area (not shown in the drawings) wherein the mannequins 1 in the special loading position C, which is the same position adopted by the mannequins in the unloading position, are once again within reach of the pushing projection means 92 which hook or grip the marked trousers and start to place them in the waiting supports 9.
