Description

Transport pallet for loading a mixing and packaging system with rollers, a system for this and a packaging process

description

The invention relates to a transport pallet for loading a mixing and packaging system with rollers, in particular paper rolls, a system with at least one Transportpa¬ lette and a mixing and packaging system and a Ver¬ drive for feeding boxes with such roles, in which the roles on stored the transport pallet, transported with the transport pallet to a mixing and Verpackungsungsanläge and emptied from the transport pallet in a Spei¬ cherbehälter the mixing and packaging plant wer¬.

Particularly suitable rolls are paper rolls such as gift paper rolls. Such wrapping paper rolls are provided with different motifs and are packed in boxes for transport and later sale, for example, in stores and supermarkets. After the delivery, the boxes are opened and the customer can himself select the rolls according to his taste. It should occur for a large selection of gift paper rolls mixed with different motives in a box.

The loading of the boxes with the wrapping paper rolls often happens by hand, in which the paper rolls are laid by hand in the cartons standing on a circulating belt webbing. There are several workers in running Direction of the webbing one behind the other and put in discre¬ ten intervals gift paper rolls, often with two different motives in the cartons. In addition to the comparatively high packaging costs, manual packaging has the disadvantage that, due to the slow speed of packaging, it can only react inadequately to peak times, such as Christmas or Easter, although appropriate seasonal motifs have already been printed and stored in a warehouse over the year be kept ready.

Attempts have already been made in the past to mechanize the packaging process. In these known mixing and packaging systems, the gift paper rolls are placed over loading stations arranged be¬ adjacent in the running direction of the webbing. To ensure that there is always a sufficient supply of gift paper rolls, a silo-like storage container stands on the loading station. This storage container in turn is filled up discontinuously with transport containers.

A changeover from the previous feeding of the Gurtban¬ by hand to a mechanical feed is particularly problematic, since for feeding the SpeI¬ cherbehälter additional conveyor systems are connected upstream of the paper rolls from the camp or by a blanking and winding unit for. Transport packaging system, and which are largely set up on standardized transport pallets and in the case of conversion, both all transport pallets exchanged for new transport container as well as the upstream conveyor systems must be umge¬. This is associated with extremely high costs. Accordingly, the invention has the object, an existing transport pallet such that a compatible use with existing mixing and packaging systems is possible. A first sub-task is to provide a system comprising at least one transport pallet and a mixing and packaging system. In a second subtask is a method for loading boxes with roles such. B. paper rolls to develop.

The object is achieved with a transport pallet for loading a mixing and packaging machine with rolls, in particular paper rolls of a predetermined roll width, comprising a base plate and a holding element engaging respectively at its front and rear ends, the rear holding element being such is formed so that a rolling of the rollers is avoided, and the front Halte¬ element comprises two front support rods whose distance zu¬ each other than the roller width, wherein between the support rods a pivotable closure element is angeord¬ net.

The bottom plate, which is essentially flat on the upper side, can be provided on its underside with feet which, for example, simplify an underride with forks of a fork-lift truck. In a particularly simple Ausgestal¬ tion, the feet are designed as two arranged under the bottom plate square profiles, which can be interrupted continuously or for better stacking one above the other also interrupted.

In a further embodiment according to the invention, the floorboard may have cross struts, which preferably also are arranged below the plate. The cross struts are usually boards, which usually run more or less senk¬ right to the longitudinal edge of the bottom plate.

The rear retaining element may be formed from two rear retaining rods which are perpendicular to the base plate in a transport position and which are preferably connected to a retaining bracket via a crosspiece. Transport position refers to the condition of the transport pallet loaded with rollers. In the case of the rear holding element, the distance of the rear holding bars from each other is selected smaller than the roller width, ie. the axial extent of the rollers. This effectively prevents the rollers from rolling during transport through the rear support member. The rollers located on the rear retaining element come to rest on the rear retaining element. The distance between the rear retaining bars of the rear retaining element can also be selected to be greater than the roll width, provided that further built-in mounting elements are present or the rear retaining element is configured as a retaining plate.

Also, the support rods of the front support member are in the transport position perpendicular to the bottom plate. However, the spacing of the holding rods is selected to be greater than the roller width, so that the rollers can pass between the holding rods if, for example, the transport pallet is inclined in the direction of the front holding element. For this purpose, however, it is necessary for the closure element to be swiveled out of the closed position during transport and to free the free installation space between the preceding holding bars of the front holding element. Advantageously, the front and / or rear Hal¬ test bars in its upper portion with a cross bar iron-like manner. As a result, the respective holding element is substantially stiffened and safer with regard to a possible risk of injury, since the holding bars no longer stand up like a stalk.

It has proved to be particularly favorable if the closure element engages pivotally on the transverse bar of the front holding element. In this embodiment, the closure element can be designed as a single rod or as a spaced double rod or as a plate and pivot about the transverse rod as a rotation axis, specifically along the spacing or plate plane. This embodiment results in the advantage that the closure element assists in aligning the rollers when the transport pallet is emptied. The rollers do not roll off the transport pallet exactly parallel to each other when the closure element is pivoted away, but are also slightly inclined relative to one another. In the embodiment described above, the open closure element acts as a baffle plate, against which the rollers abut and thereby aligned again before dropping into the storage container. In this way it is possible to avoid congestion or at least reduce it.

As an alternative to a pivotable mounting of the closure element on the cross bar, it is also possible to pivotally mount one or two closure elements on one or both holding bars of the front holding element, so that the pivot axis of the closure element or the closure elements is parallel to the extension of the holding bars ausge¬ is aligned. In this embodiment, the closure Leraent as a swinging door between the support rods wegge¬ pivots.

Preferably, the closure element can be blocked against pivoting by means of a locking mechanism. As a result, the closure element is secured against premature pivoting during transport and thus against unintentional opening. The locking mechanism may comprise ei¬ NEN hooks, bolts or magnets and cooperate with the bottom plate and / or the support rods and / or the cross bar.

Preferably, the support rods of the rear Halteele¬ Mentes and / or the front retaining element on the Boden¬ plate by means of joints, wherein the joints are fixed at least in a transport position. In further alterative embodiments, the support rods are attached by means of steering to one or more plate stands or one or more transverse boards or cross struts or engage there. As a result, it is possible for the retaining elements to be folded over when the pallets are unloaded and, as a result, the transport pallets can be stacked for storage, so that only a small storage space requirement is taken into account.

In a particular embodiment, the respective joint comprises a stationary on the bottom plate, if necessary, also arranged on the cross boards stand pipe, in which the jewei¬ time holding rod in the transport position can be inserted, wherein the respective standpipe and the respective holding rod via a spring element in continuous operative engagement , As a spring element, for example, a helical spring is geeig¬ net. Against unintentional withdrawal is the HaI- Testab protected with a pull-out fuse. The pull-out fuse itself can be configured as desired. If necessary, the joint may also comprise a hinge, wherein the holding rod is in continuous operative engagement with the hinge. The standpipe may have a larger or smaller diameter than the support rods of the respective holding element, wherein the spring coaxially with its first end in the Stand¬ tube and its second end is fixed Mentes in the holding rod of the Halteele¬. To fold over the Hal¬ test bars of the holding element are now pulled out of the uprights against the spring force of the spring element and the Halte¬ element folded. The restoring force of the Feder¬ element is designed such that in the transport position, d ^' . H. when the holding element is stationary, an unintentional Weg¬ flaps of the holding element is not possible.

As an alternative to the embodiment described above, the joint may comprise a standpipe arranged fixedly on the bottom plate, which rod is connected to the respective support rod via a hinge joint, wherein a sleeve is arranged on the respective support rod or the standpipe, which sleeve is arranged in the transport position on the Schar¬ niergelenk is pushed. To fold over the respective holding element, the sleeves are laterally displaced, preferably raised, on the holding bars, thereby releasing the respective joint, so that the holding element can be folded over.

The first partial object is achieved with a system comprising at least one transport pallet described above and a mixing and packaging system which has a storage container for feeding rollers, wherein an inclined plane is arranged in front of the storage container in such a way. net is that the roles of the standing on the inclined plane transport pallet hinein¬ roll into the storage container.

For this purpose, the inclined plane must be suitable for receiving the transport container, which is aligned with its front end to the storage container. The inclined plane can also be generated by unilateral lifting of the transport pallet with a lifting means.

Advantageously, the inclined plane has an inclination of 5 ° to 50 °, particularly preferably 10 ° to 30 °.

In principle, it is also possible to press the rollers by means of a sliding device from the transport pallet into the storage container.

The second partial object is achieved by a method using a transport pallet described above, in which the transport pallet is placed on an inclined plane arranged in front of the storage container.

In a favorable embodiment of the method, after stopping the transport pallet on the inclined plane, a pivotable closure element arranged on the transport pallet is unlocked. After unlocking the closure mechanism, the closure element oscillates in an opening position and settles in the normal force direction, that is to say essentially vertically.

The rollers are preferably mounted on the transport pallet such that the axial alignment of the rollers is selected transversely to the direction of movement of the emptying process becomes. With such an orientation of the rollers parallel to the running direction of the webbing of the mixing and packaging system, no further devices or work steps for aligning the rollers are required. According to the invention, the term paper rolls also includes all similar rolls or bar-shaped products, but in particular all paper and paperboard products.

A particularly preferred role according to the invention is a paper roll.

For a better understanding, the invention will be explained in more detail with reference to the following drawing figures. The following are shown:

1 shows a schematic side view of a transport pallet with loaded paper rolls;

2 shows a side view according to the line A - A in Fig. 1;

3 shows a view according to FIG. 1 during the emptying process; FIG. and

Fig. 4 is a schematic side view of a transport pallet with folded vor¬ and rear retaining element.

Fig. 5 shows an alternative embodiment analogous to FIG. 3 with attachment of the front Halte¬ elements on Palettenfuß. Fig. 6 shows the alternative embodiment of Fig. 5 in the folded position

FIG. 1 shows a side view of a transport pallet 1 according to the invention, on which multi-layer paper rolls 3 are loaded. In this case, the lower paper rollers 3 rest on the base plate 5. Rolling of the paper rolls 3 is prevented at the front end 6 and at the rear end 7 of the base plate 5 by a respective front support element 9 or rearward holding element 8 protruding vertically on the base plate 5.

The front holding element 9 comprises a first front holding bar 10 and a behind it located, not visible in the An¬ view of Fig. 1, second front Halte¬ 11 (see Fig. 2). Both front support rods 10, 11 are connected to a bracket via a transverse rod 17 (see also FIG.

On the cross bar 17 of the front retaining element 9 engages pivotally mounted on a closure element 13. In the closed position of the closure element 13, the paper rolls 3 can partially pass between the two front holding bars 10, 11 due to their comparatively small roll width 4 (see Fig. 2) and abut against the closure element 13.

The closure element 13 remains alone in the closed position shown due to its inertial mass. However, in order to effectively prevent inadvertent opening of the closure element 13, in particular during the transport of the transport pallet 1, it is necessary in the region of the transverse Rod 17 on the closure element 13 a Verriegelungsme¬ mechanism 18 is arranged. This is designed as a spring-biased bolt, held in the bearing bush 13a of the Verschlusse¬ element 13 and engages in the closed Stel¬ ment in a complementarily shaped bore of the transverse rod 17 a. For unlocking the Verriegelungsmecha¬ mechanism 18 is pulled out in its axial direction against the spring force, so that the closure element 13 can pivot in an open position like a flap. In an alternative embodiment (not shown in detail), the closure element 13 is held against unintentional swinging up or opening by means of a locking element (18a), which may also be arranged on the transverse boards, on the base plate 5. In this case, as a bolt, which possibly a spring or gravity-biased bolt centrally and / or possibly also introduced below the bottom plate and prevents z. B. by protruding in ge closed position an opening (swinging) of the closure element 13th

The rear holding element 8 is located at the rear end 7 of the transport pallet 1 and also comprises a first and a second rear support bar 14, 15 (see Fig. 2). Both rear support rods 14, 15 are also ver¬ by means of a transverse rod 17 in its upper end connected. The essential difference between the rear holding element 8 and the front holding element 9 consists in the fact that the distance 16 (see Fig. 2) of the rear holding bars 14, 15 is selected to be smaller than the roll width 4 (see Fig. 2), so that the paper rolls 3 directly on the Haltestä¬ ben 14, 15 come to rest. It is not possible to roll the paper rolls 3 between the rear holding bars 14, 15. For convenient handling, the transport pallet 1 is equipped with a front foot 27a and a rear leg 27b.

The width ratios between the two holding elements 8, 9 and the roll width 4 of the paper rolls 3 are particularly well evident in the view of FIG. 2 rotated by 90 ° with respect to FIG.

The front support rods 10, 11 have a larger distance 12 than the roller width 4 of the paper reels 3. Rolling of the paper reels 3 between the front support rods 10, 11 out of the image plane is prevented only by the closure element 13. The first and second rear support rods 14, 15 are mostly covered by the paper rollers 3. The distance 16 of the rear Halte¬ rods 14, 15 is chosen to be significantly smaller than the Rollen¬ width 4 of the paper rolls. 3

In Fig. 3, the transport pallet 1 is shown during the Ent¬ emptying process. The transport pallet 1 was parked on an inclined plane 24 and subsequently the locking mechanism 18 is actuated so that the paper rollers 3 roll in the direction of movement 25 from the transport pallet 1 through the front holding element 9. A stationary on the inclined plane 24 arranged stopper 28 prevents positively locking a further sliding of the transport pallet 1 in the direction of the mixing and packaging plant. 2

From the transport pallet 1 fall the paper rolls 3 directly into the storage tank 23 of the mixing and packaging system 2. The alignment of the paper rolls 3 within the storage container 23 is in line with the orientation of the paper rolls 3 on the transport pallet 1. A subsequent correction of the orientation of the paper rolls 3 rolling out of the transport pallet 1 is assumed by the closure element 13.

4 shows a transport pallet 1 after the emptying process, that is to say without paper rolls 3. To reduce the storage space, both the front holding element 9 and the rear holding element 8 were folded over. Both holding elements 8, 9 are now aligned approximately parallel to the bottom plate 5 and preferably do not protrude beyond the bottom plate 5. The folding over of the two Halte¬ elements 8, 9 is realized via joints 19. In this case, the bottom plate 5 is expediently prepared so that the holding elements 9, 8 rest in folded form more or less flush on the bottom plate.

In the embodiment of the transport pallet 1 shown in FIG. 4, the front retaining element 9 and the rear retaining element 8 are designed, for example, with different joints 19, preferably the front and / or possibly also the rear retaining element 8, 9 Joint 19 are pivotally mounted on the pallet base 27a. Usually, the transport pallets 1 are made with similar joints 19.

The hinge 19 at the front end 6 of the base plate 5 makes it possible to fold over the front holding element 9. Starting from the transport position with the holding element 9 stationary, the entire holding element 9 is supported in such a way that it can be tilted or pivoted onto the plate 5 , In In a preferred embodiment, this is done by lifting against the spring force of the spring element 21 and whereby a plug connection between the holding rod 10, 11, of which only the first front retaining bar 10 is visible, and the standpipe 20 is released. Subsequently, the front retaining element 9 can be folded. In this lying position, the front retaining element 9 rests on the bottom plate 5 with the outer wall of the bearing bush 13a of the closure element 13, while the opposite end of the closure element 13 is held by the spring element 21. In the folded-over position, the spring element 21 primarily represents a safety device for retaining the retaining element 9. To mount the front retaining element 9 in the transport position, the retaining element 9 is raised and the retaining rods 10, 11 are inserted into the respective standpipe 20 , The precise mating is supported by the restoring force of the spring element 21. In the embodiment with hinge 19, the holding element 9 is held by a corresponding stop on the hinge in a vertical position.

The hinge 19 at the rear end 7 of the bottom plate 5 deviates constructively from the hinge 19 at the front end 6. In ei¬ ner embodiment, the rear support rods 14, 15 of the rear retaining element 8 are permanently connected via a respective safety catch or via a hinge joint 26 with the standpipe 20. In the transport position, the pull-out fuse is lowered into the standpipe 20 or the hinge joint 26 is blocked. For this purpose, a sleeve 22, which is arranged displaceably on the respective rear holding bar 14, 15, is pushed over the hinge joint 26 in the transporting division. To fold the rear Halte¬ element 8, the support rods 14, 15 are raised and out pulled the standpipe or are in the alternative Aus¬ guide both sleeves 22, recognizable in Fig. 4, only the sleeve 22 of the first rear support rod 14, raised and the rear support member 8 is folded. A Ver¬ lustsicherung is not required in this embodiment, since the rear uprights 20 are continuously connected via the safety catch or on the hinge joint 26 with the rear support member 8 in combination.
