DETAILED DESCRIPTION

(14) In the following, for the same or similar components of the different representations the same or similar reference numerals are used for easier readability and understandability.

(15) A packaging material dispenser according to the invention and an apparatus for the manual or machine production of a tube-like packaging material, respectively, according to the invention is denoted in the following in general with the reference numeral 1. The apparatus 1 for the production of a tube-like packaging material from a paper supply unit in the shape of a paper strip wound up to a roll 11 comprises as main part a receiving arrangement 3 (and 3 or 3, respectively) for encompassing at least partly circumferentiatingly at least one roll, a guiding chute 5 with an opening 7 for ejecting the packaging material from a roll 11 arranged in an ejection position 50 as well as a movable transport means 9 for displacing at least one roll 11 in the ejection direction A. The paper strip each wound up to a roll 11 defines a roll axis R. The paper strip rolls are embodied coreless, in particular without cardboard core, and have a cylindrical inner hollow space 13, which is formed from the innermost layer of the paper strip. The innermost paper layer is drawn from the inner hollow space 13 of the rolls for producing packaging material.

(16) A forward orientation is defined in the ejection axial direction A by the ejection direction of the packaging material, which is referred to in the following. The receiving arrangement 3 is arranged in front of the guiding chute 5 regarding the ejection axial direction A. The respective rear-sided front side 17 of the rolls 11 faces in the direction of a rear-sided refill opening side of the apparatus 1 in the embodiments shown in FIGS. 1a to 1d. The receiving arrangement 3 can be opened essentially completely circumferentiatingly at the refill rear side of the apparatus 1.

(17) As long as the layers of the roll 4 wound up around each other are still in the static friction state, as shown schematically in FIGS. 1B and 1C, the front-sided front side 16 of the roll 11 forms a flat, slightly conical (i.e. with an opening angle of almost 180) front face 16, which can get in touching contact at the front face with the inner contour 51 of the guiding chute 5 along its outer circumference when introducing the rolls 11 into the apparatus 1.

(18) With the embodiments of the packaging material dispenser 1 shown in FIGS. 1A to 1D, the paper strip rolls 11 are held in a cylinder half shell-shaped receiving arrangement 3 being formed essentially form-complementarily to the outer circumference of the paper roll 11. The half shell surrounds the rolls 11 in circumference direction with an overlap of about 180, such as between 160 and 200. The innermost paper layer is drawn from the inner hollow space 13 for producing the packaging material along the chute-like inner contour 150 of the guiding chute 5 and is provided as spiral tube-shaped packaging material by its ejection opening 7.

(19) The shell-shaped receiving arrangement 3 shown in FIGS. 1A to 1D, 2A and 2B can be produced in one piece from a cylinder shell-shaped, thin walling, for example of plastics, with a wall thickness of up to 5 mm or less. It is thinkable, that the receiving arrangement 3 consists of a different material, for example sheet metal. The rolls 11 and the receiving arrangement 3 are dimensioned in an attuned manner to each other that they are formed essentially form-complementary to each other, for example annularly, and/or formed coaxially and almost coaxially to each other, respectively, wherein a deviation of the coaxiality of a few centimeters, for example 0.5 cm to 3 cm, can be tolerable.

(20) The guiding chute 5 of the embodiment shown in FIGS. 1A to 1D follows up in the axial direction A the front-sided end of the receiving arrangement 3 directly in the embodiment shown in FIGS. 1A to 1C. The inlet region of the guiding chute has a for example cylindrical base cross-section, from which a cone section-shaped guiding inner contour 51 narrows around a chute axis T in the direction of the ejection opening 7. The guiding inner contour 51 runs from the receiving unit 3 to the ejection opening 7 unobstructedly. The guiding chute 5 can be made one-pieced of one single piece, for example an ejection-molded plastic part or a part made of several plastic components. The guiding chute 5 has a walling, which can have an essentially constant wall thickness of 1 mm to 5 mm along the complete axial extension of the guiding chute.

(21) The guiding chute 5 has at its inner side a guiding inner contour 75 narrowing from the receiving unit 3 in the direction of the ejection opening 7 chute-like. The chute-like narrowing guiding inner contour 51 defines a chute axis T. Between the chute axis T and the guiding inner contour 51, a chute opening angle is spanned. In general, a chute opening angle being variable in circumferential direction progression can be realized. It can be that the roll axis R, the chute axis T and the ejection axial direction A are aligned coaxially to each other, as for example shown in the embodiment of FIGS. 2A and 2B.

(22) The FIGS. 1A to 1D each show the same apparatus and deviate in the number of rolls 11 present in the receiving arrangement 3 as well as in its position inside the receiving arrangement 3 and the position of the transport means 9.

(23) In FIG. 1A, three rolls 11 lie sequentially behind each other in the receiving arrangement 3 in the axial direction A. The frontmost roll 11 in the ejection direction A has a front-sided front side 16, which is arranged directly adjacent to the guiding chute 5. When the paper strip is stripped off from the inner side 13 of the frontmost roll 11 and is ejected through the opening of the guiding chute 5, a touching contact to the front side 16 can occur. A complete or at least partly touching contact between the front-sided front side 16 and the inner side 51 of the guiding chute can be present when ejecting spiral-shaped and chute-like, respectively, packaging material through the opening 7 of the guiding chute 5 (not further depicted; it is referred to DE 20 2012 009 025 U1 for further explanations).

(24) The frontmost roll 11 in the ejection direction A (FIGS. 1A, 1C and 1D) is located in the ejection position 50. When the frontmost roll 11 is completely unwound by drawing the paper strip from the inner hollow space 13 of the roll 11 and is thereby entirely consumed, the receiving arrangement 3 at the ejection position 5 is empty, as shown in FIG. 1B. The rolls 11 in the receiving arrangement 3 shown in FIG. 1B are not in the ejection position 15. When the ejection position 15 is not occupied with a roll 11, as shown in FIG. 1B, the user cannot readily produce further packaging material by drawing off a paper strip from a roll in the receiving arrangement 3 and drawing through the opening 7 of the guiding chute for effectuating a forming of the paper strip into a packaging material.

(25) A roll 11 (or several rolls 11), which is carried along by the transport means 9, can be brought into the ejection position 50 by, as shown in FIG. 1C, being transported by the transport means 9 from the engagement position shown in FIG. 1B into the ejection position shown in FIG. 1C. For this purpose, the rear-sided rolls 11 (FIG. 1B) can be displaced by at least one roll length 1 to the front in the ejection direction A.

(26) In order to achieve a movement of at least one roll 11 into a receiving arrangement 3 of an apparatus for the production of a tube-like packaging material, transport means 9 of various designs can be employed. The transport means can be realized as translation movable linear conveying means, for example as gear rack, conveying belt, conveying chain or such. In the embodiment shown in the Figures, the transport means 9 is realized by a pull rod 93 with wedge-shaped carrier 8a, 8b and an activation handle 91. Such a manually activatable transport means 9 can be for realizing a design most simple, particularly free of electronic components, particularly for realizing a purely manual arrangement for the production of a tube-like packaging material. Alternatively, a machine apparatus for the production of a tube-like packaging material, which can have particularly a machine-supported and motor-drive, respectively, forming unit, with which the motorized transport means, could be provided for example comprising an electronic activation button for activating an electronic drive motor for example for a conveying belt, a conveying chain or such, can be provided (not further depicted). For example, a pull rod or such can be provided for the activation of the apparatus from the rear side for example by reloading staff (not further depicted).

(27) Different from the embodiment of FIGS. 2A and 2B, the ejection axial direction A according to the embodiment of FIG. 1A to 1D is eccentrically spaced relatively to the roll axis R. The chute axis T extends with an angle displacement relatively to the roll axis R.

(28) The ejection axial direction A relative to the roll axis R according to the embodiment according to FIGS. 2A and 2B are displaced by an angle displacement. The chute axis T runs parallel to the ejection axis A and forms a chute inner contour 5 relatively to the roll axis R, essentially according to an oblique cone.

(29) In the following, the function of the transport unit 9 is described, as shown in FIG. 1A-1D (as well as FIGS. 2A and 2B). A guiding comprising two guiding profiles 95 is arranged in the transverse direction Q vertically beneath the receiving arrangement 3 and its shell body, respectively. The pull rod 93 is slidingly supported in the guiding 95. Carriers that are realized here exemplarily as tiltable wedges 8a, 8b are stationarily supported at the pull rod 93. The transport means is, as apparent in FIG. 1B, designed in such a way that for each roll remaining in the receiving arrangement 3 after the frontmost roll is consumed an individually assigned carrier in the shape of each of a wedge 8a or 8b is provided. It is thinkable that instead, for all remaining rolls 11, a single, mutual carrier is provided that for example can be realized according to the carrier wedge 8b.

(30) The transport means 9 is movable by at least one roll length 1 in the direction of the roll longitudinal axis A. It can be that at least one stopper is provided, which for example can be arranged at the guiding 95, the receiving arrangement 3 and/or the transport means, for limiting the linear movability of the transport means 9 in the direction of the roll longitudinal axis A to a predetermined maximum. A stopper or several stoppers can for example be provided for inhibiting a falling out of the transport means 9 of the guiding 95 and/or to define at least one position of the transport means, for example the engagement position and/or the ejection position.

(31) In FIGS. 1A, 1b and 1d, the transport means 9 is located in a rear engagement position. In this engagement position, the rearmost carrier, which is realized here as tiltable wedge 8b arranged behind the rearmost roll 11 with respect to the ejection direction A for being brought in a touching contact with the rear-sided front side 17 of the rearmost roll 11.

(32) In FIG. 1C, the transport means is brought into a front-sidedly displaced ejection position, for example by pulling the handle 91, for bringing the roll 11 previously displaced backwards (cf. FIG. 1b) into the ejection position 50 (cf. FIG. 1C). When pulling the pull rod 93 to the front, the rear-sided carrier comes into touching contact with the rear-sided roll 11 and moves the same along the roll longitudinal axis R towards the guiding chute 5. Further rolls 11 lying in front of the rear-sided roll 11 (here: a roll 11) are carried along with the movement of the rear-sided roll 11. It is thinkable that the distance between the two rolls 11 shown in FIGS. 1B and 1C is dimensioned greater than a roll length 1 (not further depicted) so that also a front-sided carrier, similar to the depicted tiltable wedge 8a, can be in a touching contact with the rear side of the front-sided roll 11 for directly applying a carrier force from the transport means (without force transmission by moving the roll).

(33) In the embodiments shown in FIGS. 1A to 1D, the carriers are exemplarily realized as wedges 8a, 8b. The wedges 8a and 8b, respectively, are arrowed against the ejection direction A. The wedges 8a, 8b are tiltable by a respective tilting axis W and are supported at the transport means, here exemplarily the pull rod 93. The wedges 8a, 8b are spring pre-tensed in such a way that they can take an active transport position (as shown in FIG. 1D), in which the respective carrier is protruding into the receiving arrangement 3 for achieving a touching contact with the roll 11 for carrying the same along. A front-sided side in the ejection direction A, a wedge 8a and 8b, respectively, can be flat. The receiving arrangement 3 can have at least one axis opening for at least one carrier, for example a guiding long hole. It is thinkable that the receiving arrangement 3 has an individual axis opening for each transport means 9. The spring pre-tension of a carrier, for example of the front-sided wedge 8a, can be dimensioned in such a way that it is possible to shift the transport means against the ejection direction, wherein the front-sided carrier realized as wedge 8a does not exert a carrying effect regarding the rolls 11, but is arranged beneath the rolls 11 and slides along at the outer side of the roll 11 or rolls 11.

(34) A rear-sided carrier, such as the wedge 8b, can be tiltable between an active position and a passive position for allowing that a roll 11 can be refilled in the receiving arrangement 3 from the packing station 10 without the carrier (here: wedge 8b) standing in the way (cf. FIG. 2b).

(35) FIGS. 2A and 2B show a packing station. Similar to the packing stations known from the prior art, the packing station depicted schematically here comprises a table-like contact face 104, on which shipping containers can be placed for being filled with packaging material by staff standing at the front side 103 of the packing station 100. The contact face 104 can be supported by a frame 101.

(36) The frame 101 supports at least one apparatus for the manual or machine production of a tube-like packaging material from a paper strip wound up to a roll 11. The apparatus, which is integrated into the frame 101 and is supported by the frame 101, can be realized as described above. The packing station 100 is designed with a receiving arrangement 3 for encompassing at least one roll 11, particularly several rolls arranged sequentially behind each other in the ejection direction A (in FIG. 2B: three rolls 11), at least partly circumferentiatingly.

(37) At the front side 103 of the frame 101, paper for forming the packaging material can be drawn from the inner side 13 of the front-sided roll 11. At the rear side 105 of the frame 101, the receiving arrangement 3 is occupiable with at least one further roll 11 for example by a different person than the packing staff standing at the front side 103.

(38) The apparatus of the embodiment of the packing station 100 shown in FIGS. 2A and 2B is arranged completely beneath the frame upper side 107 of the frame 101. The frame 101 forms, well recognizable in FIG. 2A, a tunnel-like duct through which the receiving arrangement 3 of the apparatus is extending. The receiving arrangement 3 and the roll axis R, respectively can extend thereby essentially horizontally through the frame 101. In particular, the tilting of the receiving unit and the roll axis, respectively, is tilted less than 10 or less than 5 with respect to a horizontal. A possible horizontal extension of the roll axis R allows transferring the weight of the roll 11 homogeneously and/or largely from the bottom side of the roll(s) 11 to the receiving arrangement 3, which is gentle to the material. At the same time, a horizontal arrangement of the receiving arrangement 3 and/or the roll axis R allows a relatively great control of the position and the positioning of the roll 11 in the receiving position 3, so that the roll(s) 11 cannot slip owing to gravity.

(39) Receiving arrangements can also be formed differently from the receiving arrangement 3 with a half shell-shaped body. As an example, a receiving arrangement 3, as shown in FIG. 3, of struts and ribs, respectively, for example at least 2, at least 3, at least 4, or more struts being arranged parallel to the roll axis R on which at least one roll 11 is lying. In an alternative embodiment of the receiving arrangement 3 according to FIG. 4, the receiving arrangement 3 is formed by a wave-like bent plate 33 having a curved receiving section, which more or less matches with the curvature of the outer circumference faces of the rolls 11 and which can extend over the width of 60 to 120 along the outer side of a roll 11.

(40) FIG. 5A shows a perspective view of an alternative embodiment of an apparatus 1* according to the invention for the production of a tube-like packaging material from a paper strip folded or stacked from a paper supply unit in the shape of a Leporello stack 11*.

(41) The apparatus 1* comprises, as the above-described apparatus 1 for the production of a tube-like packaging material from a paper supply unit in the shape of a paper strip wound up to a roll 11 as main component a receiving arrangement 3* (according to FIG. 7: 3**, respectively) for encompassing at least one Leporello stack, a guiding chute 5 with an opening 7 for ejecting the packaging material from a stack unit 11* arranged in an ejection position 50 as well as a movable transport means 9 for displacing the at least one Leporello stack 11* in the ejection direction A at least partially circumferentiatingly.

(42) A Leporello stack is typically essentially cuboid with a height h, a length 1 and a width b. The upper side 13* and the corresponding typical parallel bottom side 14* of the Leporello stack 11*, respectively, each define an even surface (l*b). The Leporello stack 11* can, as shown exemplarily, be essentially cuboid, wherein the front-sided front face 15 and the rear-sided front face 17 (b*h) is orientated in the ejection axial direction A and wherein the side faces (without reference numerals; l*h) extend in the longitudinal direction L of the Leporello stack and the paper strip and essentially in the ejection direction A, respectively. The apparatus 1* according to FIGS. 5A and 5B deviates from the apparatus 1 according to FIG. 1A to 1D essentially only by the type of the received paper supply unit and the corresponding adapted shape of the receiving arrangement 3 and 3*, respectively.

(43) In FIGS. 5A and 5B, the transport unit 9 is provided as pull rod 93 laterally next to the receiving arrangement 3* (stable according to FIG. 1A to 1D beneath the receiving arrangement 3). It is thinkable that the transport means 9 of the embodiment shown in FIGS. 5A and 5B are arranged beneath the receiving arrangement 3*.

(44) Regarding the function of the apparatus 1*, it is referred to the description in FIG. 1A to 1D as well as 2A and 2B, because essentially the same actuation is realized in the apparatus 1* as in the above-described embodiment.

(45) The packaging material is drawn off from a Leporello stack (11*)-shaped supply unit from the upper side 13* of the stack 11*. It is thinkable that the paper strip is stripped off from the front-sided front face 5 of the stack 11*, if for example the stack 11* would be orientated downwards in the vertical direction with the folding edges of the side defined by the series of layers of the Leporello stack.

(46) The packing station 100 shown perspectively in FIG. 6 essentially complies with the packing station 100, wherein instead of the above-described apparatus 1 for receiving roll-shaped paper supply units, an apparatus 1* for receiving Leporello stack-shaped supply units is provided.

(47) FIG. 7 essentially complies with FIG. 3, wherein the receiving arrangement 3** formed by two struts is provided for receiving the Leporello stack-shaped supply units. As shown in FIG. 7, the struts can be formed with cuboid cross-section, and form a strut upper side, which is orientated essentially flushing with the bottom side 14* of the Leporello stack 11*. It shall be clear that the struts of the receiving arrangement 3** as shown in FIG. 7 can also have a different cross-sectional shape, for example a round cross-sectional shape, or that for a Leporello stack 11* as original material also a different kind of receiving arrangement, for example the half-cylindrical receiving arrangement 3, the receiving arrangement 3* formed by two oblique struts, or even by a receiving arrangement 3** formed by a waved sheet metal, can be provided. It is also thinkable that a paper supply unit in the shape of a roll 11 can be supported in a receiving arrangement with essentially rectangular cross-section, such as the receiving arrangement 3** shown in FIGS. 5A and 5B, or be supported on the parallel, flat struts of the receiving arrangement 3** according to FIG. 7.
