[0053] While the invention will be described in connection with certain preferred embodiments, there is no intent to limit it to those embodiments. On the contrary, the intent is to cover all alternatives, modifications and equivalents as included within the spirit and scope of the invention as defined by the appended claims.

DETAILED DESCRIPTION OF THE INVENTION

[0054] In FIG. 1 a finger element 1 which permits an auto-adaptive deformation is shown. The finger element 1 has two flank elements 2, 3 which in the finger element 1, which is shown and in this regard preferred, run together from one end 4 of the finger element 1 to the opposing end 5 of the finger element 1. Additionally, the flank elements 2, 3 approach one another continuously in a longitudinal direction of the finger element 1. Whilst the flank elements 2, 3 are spaced apart from one another at one end 4 of the finger element 1, the flank elements 2, 3 at the other end 5 of the finger element 1 are directly connected together. Thus, a finger element 1 which tapers and runs conically in one direction is obtained.

[0055] Webs 6 are provided between the flank elements 2, 3 so as to be distributed over the length of the finger element 1, the flank elements 2, 3 being connected together thereby. In the finger element 1, which is shown and in this regard preferred, the webs 6 are connected via joints at both opposing ends 7, 8 in an articulated manner to the flank elements 2, 3. Alternatively, the webs 6 could be flexibly configured. The webs 6 in the finger element 1, which is shown and in this regard preferred, are distributed at equal spacings over the length of the finger element 1. However, this is not absolutely necessary. It is also not absolutely necessary that the webs 6, as in the finger element 1 shown, run parallel to one another. It is preferred, however, that the webs 6 enclose with each of the flank elements 2, 3 an acute angle a on one side and an obtuse angle β on the opposing side.

[0056] The flank elements 2, 3, which are shown and in this regard preferred, are flexibly configured so that the flank elements 2, 3 may be bent about an axis perpendicular to the longitudinal extension of the finger element 1, which is shown in particular in FIGS. 2A-C. To this end it is expedient if the flank elements 2, 3 are formed from a flexible plastic or, for example, rubber. The webs 6 may also be formed from plastics or, for example, from a metal since the webs 6 do not have to have any flexibility. In FIG. 2A, the finger element 1 of FIG. 1 is shown in an initial position in which the finger element 1 is in an extended orientation, wherein the free ends of the flank elements 2, 3 are arranged in one plane E. In the finger element 1, which is shown and in this regard preferred, the flank elements 2, 3 in this position are configured at least substantially symmetrically to one another.

[0057] If according to FIG. 2B relative to the initial position the free end of the upper flank element 2 is now displaced to the front out of the plane E shown in the longitudinal direction of the finger element 1, the finger element 1 curves downwardly as a result of the connection of the flank elements 2, 3 via the plurality of webs 6. In this manner the end 5 of the finger element 1, which is shown to the right, is adjusted downwardly. Similarly, the finger unit 1 according to FIG. 2C is curved upwardly, wherein the corresponding end 5 of the finger element 1 is adjusted upwardly when the free end of the lower flank element 3 in the longitudinal direction of the finger element 1 is displaced from the plane E to the front in the direction of the curving tip of the finger element 1. It may also be seen in FIGS. 2A-C that the webs 6 between the flank elements 2, 3 are inclined in different directions when the finger element 1 is curved.

[0058] In order to implement the displacement of the flank elements 2, 3 similar to FIGS. 2A-C, a drive unit, not shown, may be provided. In this case suitable drive units are known from the prior art. Suitable drive units, for example, may have at least one linear drive. Thus at least one flank element 2, 3 may be adjusted forward and back in a simple manner in the longitudinal direction of the finger element 1.

[0059] It is not shown that also more than two, for example at least three or four, flank elements may be provided. For the sake of simplicity, these flank elements may be arranged, in particular, equally distributed about a longitudinal axis of the finger element. The plurality of flank elements may thus run together into a common point of the finger element, in particular with free ends. Additionally or alternatively, preferably in each case the webs may connect together all of the flank elements. The flank elements 2, 3, which are shown and in this regard preferred, are configured to be strip-shaped. However, a plate-shaped or bar-shaped embodiment of the flank elements might also be possible.

[0060] The described finger element 1, however, may be adjusted quite differently from that shown in FIGS. 2A-C, and according to FIG. 3, which shows an auto-adaptive adjustment of a flank element 2, 3 of the finger element 1, whilst a flank element 2 presses onto a package 9 and is bent at the same time. The corresponding flank element 2 is displaced locally in the direction of the compressive force F inwardly relative to the finger element 1, which as a result of the coupling of the flank elements 2, 3 via the webs 6 leads to the flank element 2 at another point and in the direction of the two ends 10 of the flank elements 1 connected together at the end 5 of the finger unit 5, shown on the left, being curved in the direction of the package 9. As a result, the package 9 is partially encompassed by the finger element 1. A similar auto-adaptive adjustment of the finger element 1 takes place when the package presses from above against the upper flank element 2 of the finger element 1, wherein the free end of the finger element however is adjusted upwardly counter to the view of FIG. 3. The finger element is thus curved in a quite different manner from that shown in FIG. 3.

[0061] In FIG. 4 a belt conveying device 11 is shown in which the supporting structure 12 of the belt conveying device 11 consists of a finger element 1 according to FIG. 1. The belt conveyor 13 of the belt conveying device 11 runs around the supporting structure 12 and thus around the finger element 1. To this end the belt conveying device 11, which is shown and in this regard preferred, has a plurality of deflecting devices in the form of deflection rollers 15, 16, 17. A deflection roller 15 is provided at the ends 10 of the flank elements 2, 3 connected together, wherein the deflection roller 15 is ultimately borne and supported by the corresponding end 5 of the finger element 1. Moreover, in each case a deflecting device in the form of a deflection roller 16, 17 is provided at the free ends of the flank elements 2, 3. Moreover, a drive 18 is provided, said drive in the belt conveying device 13, which is shown and in this regard preferred, being able to drive the belt conveyor 13 in different directions. The drive 18 is implemented via a drive roller 19 which as required may be adjusted to tension the conveyor belt 13, for example in the longitudinal direction of the finger element 1. Additionally, for a slip-free drive of the conveyor belt 13, a toothing may be provided on the conveyor belt 13, said toothing meshing with a toothing of the drive roller 19. In contrast to the belt conveying device 11, which is shown and in this regard preferred, the supporting structure 12 about which the conveyor belt 13 circulates may have further supporting structure parts in addition to the finger element 1.

[0062] In the belt conveying device 11, which is shown and in this regard preferred, the conveyor belt 13 is guided along the flank elements 2, 3 and namely so close that the conveyor belt 13 may be pressed by a package 9 against a flank element 2, 3 as required. The finger element 1 in this case may be adjusted in an auto-adaptive or proactive manner relative to the corresponding package 9, as has been already described. In the case of the finger element 1 of the belt conveying device 11 shown in FIG. 4, therefore, the flank elements 2, 3 are also displaced in the longitudinal direction of the finger element 1 relative to one another in order to curve the finger element 1. With the adjustment of an end 5 of the finger element 1 associated therewith in a direction perpendicular to the longitudinal extension of the finger element 1 the conveyor belt 13 and the path thereof are also adjusted around the finger element 1. If the conveyor belt 13, also in the case of a curved finger element 1, is to be guided at a small spacing from the flank elements 2, 3 along said flank elements, further devices, not shown, for positioning the conveyor belt 13 between the deflection rollers 15, 16, 17 adjoining the flank elements 2, 3 or at least one flank element 2, 3 have to be provided as required.

[0063] In FIGS. 5A-D the method for loading a container 20 with packages 21 is illustrated in individual steps. The container 20 in this case is a swap container which has been positioned on its legs 22 on a loading ramp 23. The container 20, after having been loaded with packages 21, may be driven under by a utility vehicle, namely in the form of a trailer, and coupled to the utility vehicle. The legs 22 may then be pivoted up and the container 20 driven with the utility vehicle on the public road network. The container 20 is open on its rear face 24, two leaf doors 25 having been pivoted into an open position. Then a guide device 26 of a device 27 for loading the container 20 is partially moved into the container 20, for which the guide device 26 comprises a telescopable guide system 52 by which the guide device 26 may be displaced forward and back in the loading direction B.

[0064] The container 20 and the guide device 26 are additionally shown in FIG. 6 in a perspective view with the container 20 already almost loaded. In this perspective view, in particular, the construction of the device 27 and of the guide device 26 is more clearly visible. Hereinafter, therefore, reference is initially made to FIGS. 5A-D and FIG. 6 together.

[0065] The guide device 26 has two upright elements 28, two guides 29, 30 being arranged therebetween. A further guide 32 is fixed via a slide element 31 on a lower guide 29. The slide element 31 permits an adjustment of the further guide 32 to the left and right, by the slide element 31 being able to be displaced along the associated guide 29 to the left and right. Relative to the slide element 31, in turn the further guide 32 may be adjusted to the front and rear. Additionally, the lower guide 29 extending between the upright elements 28 may be displaced upwardly and downwardly, to this end the corresponding guide 29 being correspondingly displaceably mounted on the upright elements 28.

[0066] In the exemplary embodiment, which is shown and in this regard preferred, the guide device 26 is configured in the form of a rail device, wherein the lower guide 29 and the further guide 32 of the guide device 26 are configured as the lower rail and further rail. Thus, the guide system 52 in the embodiment, which is shown and in this regard preferred, may also be understood as a rail system.

[0067] The corresponding guide 29 is assigned a conveying device 33 in the form of a belt conveying device which may also be adjusted upwardly and downwardly and which supplies separated packages 21. The front end of the conveying device 33 is assigned a hand element 34 which is provided with a plurality of finger elements 35 and thus may take the packages 21 from the conveying device 33. The packages 21 in the device 27, which is shown and in this regard preferred, are allowed to drop from the conveying device 33 into the hand element 34 which holds the packages 21 by corresponding adjustment of the finger elements 35, utilizing the already described fin ray effect of the finger elements 35 similar to a partially open human hand, the hand inner surface thereof being turned upwardly.

[0068] The hand element 34 is provided on the front end of the further guide 32 and by adjustment of the lower guide 29 and the further guide 32 may now deposit the packages 21 via a front section of the loading space 36 of the container 20 into individual layers 37 as shown in FIG. 5A. This takes place, for example, by a lowering of the finger elements 35 of the hand element 34, by a stretching of the finger elements 35 of the hand element 24 and/or by a spreading of the finger elements 35 of the hand element 34. The extent of the individual layers 37 in this case is predetermined substantially by the length of the lower guide 29 and the further guide 32. In this manner initially in the front section of the loading space 36 a column 38 extending over the width of the loading space 36 is formed from a plurality of layers 37 of packages 21 arranged one on top of the other, wherein the hand element 34 deposits the packages 21 more or less one after the other in the corresponding layers 37 and thus ultimately forms a stack 39 of packages 21. This stack 39 of packages 21 is composed of individual columns 38 of packages 21 which transition into one another.

[0069] If a column 38 extends upwardly into the region of the roof 40 of the container 20, there no longer remains sufficient space between the upper edge of the column 38 and the roof 40 of the container 20 in order to deposit further packages 21 on the column 38 in the described manner, as shown in FIG. 5B. To this end, a further upper hand element 41, which is fixed via a multi-axle arm 42 to a slide element 43 on the upper guide 30, is used. The upper guide 30 extends between the upright elements 28, as does the lower guide 29, wherein the slide element 43 may be displaced to the left and right along the upper guide 30. Additionally, the upper slide element 43 may be pivoted about the associated upper guide 30, wherein the pivot axis is oriented at least substantially parallel to the longitudinal axis of the upper guide 30. In addition to this pivot joint 44, the multi-axle arm 42 has two further pivot joints 45, 46, the central pivot joint 45 thereof having a pivot axis which is oriented at least substantially at right angles to the pivot axes of the two outer pivot joints 44, 46. As a result of the multi-axle arm 42, the upper hand element 41, to which a plurality of finger elements 47 is also assigned, may take individual packages 21 from the conveying device 33 and place the packages in the gap 48 between the roof 40 and the column 38 of packages 21. The packages 21 then reach as far as the roof 40 or at least close to the roof 40, as required, in order to be able to utilize as efficiently as possible the loading space 36 of the container 20.

[0070] Since the multi-axle arm 42 only has a limited range and, in principle, this also applies to the lower hand element 34, in many cases it is not preferred if the individual layers 37, which are created when loading the container 20 without interruption, extend over the entire length and the entire width of the loading space 36 of the container 20. Instead it is expedient to form the stack 39 of packages 21 in the loading space 36 of the container 20 via individual columns 38 which are created one after the other and thus may transition into one another such that then it is no longer possible to differentiate between the individual columns 38. The term column 38 is thus to be understood less in the conventional sense. The term column 38 is preferably intended to illustrate that the stack 39 of packages 21 initially grows upwardly in specific sections of the loading space 36 of the container 20 and, in particular, as far as the roof 40 or close to the roof 40 and in other sections of the loading space 36 in a later operating step grows upwardly and namely in turn preferably as far as the roof 40 or close to the roof 40.

[0071] This process is illustrated in FIGS. 5C and 5D. After a column 38 of packages 21 has been created adjacent to the front wall 49 of the container 20, the guide device 26 is pulled back slightly in order to create space for a further column 38 of packages 21 which is intended to blend in with the already created column 38 of packages 21. Then the second column 38 of packages 21 is created in a lower section by the lower hand element 34, as has been described already in combination with FIG. 5A for the front column 38 of packages 21. When the second column 38 of the stack 39 of packages 21 has reached a specific height, the remaining gap 48 between the packages 21 and the roof 40 of the container 20 is filled with the upper hand element 41, as has already been described in connection with FIG. 5B. Then the steps according to FIGS. 5C and 5D are carried out repeatedly one after the other until the container 20 is loaded with packages 21 as far as the opening of the rear face 24.

[0072] In the exemplary embodiment, which is shown and in this regard preferred, the device 27 for loading the container 20 has an optical sensor 50 in the form of a camera and a control device 51. The loading space 36 of the container 20 to be loaded with packages 21, the layer of the stack 39 of already deposited packages 21, the contour of the stack 21 and/or the contour of the front face 53 of the stack 39 of already deposited packages 21 are determined via the sensor 50. Using this information the lower hand element 34 and/or the upper hand element 41 may then be displaced from left to right, i.e. over the width of the loading space 36 along the associated guides 29, 30 provided between the upright elements 28. Alternatively or additionally, however, the lower hand element 34 and/or the upper hand element 41 may also be adjusted forward and back using the corresponding information detected by the sensor 50, i.e. in the loading direction B and/or in the longitudinal direction of the container 20. In the upper hand element 41, this takes place via the multi-axle arm 42 whilst in the lower hand element 34 this takes place via the associated further guide 32. Additionally, in the exemplary embodiment which is shown and in this regard preferred, using the aforementioned information the upper hand element 41, the lower hand element 34 and the conveying device 33 may be lifted and lowered. For the height adjustment of the lower hand element 34, the lower guide 29 extending between the upright elements 28 is moved up and down along the upright elements 28. For the sake of simplicity, in this case the height adjustment of the upper hand element 41 takes place via the associated multi-axle arm 42.
