Description

The The invention relates to a transport pallet for feeding a mixed and packaging machine with rollers, especially paper rolls, a System with at least one transport pallet and a mixed and Packaging plant and a method for loading boxes with such roles, in which the rollers on the transport pallet stored, with the transport pallet to a mixing and packaging plant transported and transported from the transport pallet into a storage container Emptied mixing and packaging system.

When Rolls come in particular paper rolls such as gift paper rolls in question. Such gift paper rolls are available with different Motives provided and will be for the transport and the later For example, in department stores and supermarkets packed in boxes. After delivery, the boxes are opened and The customer can choose the roles according to his taste find out yourself. It should be for a large selection of gift rolls mixed with different motives in a cardboard box.

The Loading the boxes with the wrapping paper rolls often happens in Handwork in which the paper rolls by hand in the on a revolving Webbing cartons are placed. There are several workers in running direction of the webbing one behind the other and put in discrete intervals Wrapping paper rolls, often with two different designs, in the boxes. In addition to the comparatively high packaging costs, the packaging by hand has the disadvantage that due to the slow packaging speed only insufficient at peak times, such as. Christmas or Easter, can be reacted, though over the Year already printed corresponding seasonal motifs and in one Be kept in stock.

In Efforts have already been made in the past, the packaging process to mechanize. In these known mixing and packaging systems The Wrapping Paper Rolls Over in the direction of the webbing adjacent arranged loading stations given up. So always a sufficient supply of gift paper rolls is present on the loading station is a silo-like storage container. This Storage container turn is filled discontinuously with transport containers.

A Changeover from the previous loading of the webbing by hand on a mechanical feed is particularly problematic therefore since for the storage of the storage containers additionally conveyor systems are connected upstream, which the paper rolls from the camp or by a blanking and winding unit transport to the packaging plant, and which largely on standardized transport pallets are set up and in case the conversion of all transport pallets against new transport containers replaced and the upstream conveyor systems must be changed. This is associated with extremely high costs.

As a result, the invention is based on the object, an existing transport pallet in such a way that a compatible use with existing Mixing and packaging equipment is possible. A first subtask is to have at least one transport palette and to provide a system comprising a mixing and packaging system. In a second subtask is a method for loading Cartons with rolls, such. B. to develop paper rolls.

The The task is performed with a transport pallet for loading a mixed and packaging machine with rollers, especially paper rolls one solved given roll width, comprising a bottom plate and each at the front and rear end engaging retaining element, wherein the rear retaining element is designed such that a rolling of the rollers is avoided, and the front retaining element comprises two front support rods, whose distance from each other is wider than the roll width, wherein between the support rods a pivotable closure element is arranged.

The on the top essentially flat bottom plate can on its Bottom provided with feet for example, a driving under with forks of a forklift simplify. In a particularly simple embodiment, the Feet as two formed under the bottom plate arranged square profiles, the continuous or even for better stacking one above the other also interrupted could be.

In a further embodiment of the invention can the bottom plate cross struts, which are preferably also below the plate are arranged. The cross struts are usually boards, which usually run more or less perpendicular to the longitudinal edge of the bottom plate.

The rear retaining element may be formed from two rear support rods which are perpendicular to the base plate in a transport position and which are preferably connected to a retaining bracket via a crosspiece. Under transport position is understood loaded with roles state of the transport pallet. In this case, the distance of the rear support rods from each other is selected smaller than the roller width, ie the axial extent of the rollers in the rear support member. 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 holding element are vertical in the transport position to the bottom plate. The distance of the support rods is greater than the roll width is selected, so that the rollers can pass between the support rods when for example, the transport pallet in the direction of the front holding element is inclined. For this purpose, however, it is necessary that the closure element out of the while the transport closed position is swung out and the free space between the front support rods of the front support member releases.

advantageously, are the front and / or rear support rods in their upper section bow-like with a crossbar connected. As a result, the respective holding element is substantially stiffened and with regard to a possible Danger of injury safer, since the support rods no longer stand up like a stalk.

When very cheap it has been found, when the closure element pivotally mounted on the cross bar the front retaining element attacks. The closure element can in this embodiment as single rod or as a spaced double rod or as a plate be formed and pivot about the crossbar as a rotation axis, and in particular along the distance or plate level. From this embodiment results in the advantage that the closure element during emptying the transport palette supports aligning the roles. The Rollers do not roll when the closure element is pivoted away exactly parallel to each other from the transport pallet, but imagine also slightly oblique to each other. In the embodiment described above the open works Closure element as a baffle against which the rollers and push thereby be aligned again before falling into the storage container. In this way it is possible To avoid or at least reduce traffic jams.

alternative to a pivotable mounting of the closure element on the crossbar it is also possible one or two closure elements on one or both support rods of the pivotally support the front holding element, so that the pivot axis the closure element or the closure elements parallel to the extension of the support rods is aligned. In this embodiment, the closure is ele- ment like a swinging door between the support rods pivoted away.

Preferably is the closure element with a locking mechanism against a panning lockable. As a result, the closure element against a premature panning during the Transportes and thus secured against unintentional opening. The locking mechanism can be a hook, bolt or magnet include and with the bottom plate and / or the support rods and / or interact with the cross bar.

Preferably grab the support rods the rear retaining element and / or the front retaining element to the bottom plate by means of joints, the joints at least can be fixed in a transport position. In other alternatives embodiments are the support rods by means of joints on one or more plate feet or one or more transverse boards or cross struts attached or attack there. This makes it possible for the retaining elements when unloaded transport pallets folded and thereby the transport pallets can be stacked for storage so that only a small storage space requirement is claimed.

In a particular embodiment, the respective joint comprises a stationary on the bottom plate, if necessary, also on the transverse boards arranged standpipe, in which the respective support rod in the transport position can be inserted, wherein the respective standpipe and the respective support rod via a spring element in continuous operative engagement. As a spring element, for example, a coil spring is suitable. Against unintentional pulling out of the Hal testab is protected with a pull-out protection. The pull-out protection 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 is coaxially fixed with its first end in the standpipe and its second end in the holding rod of the holding element. To fold down now the support rods of the holding element are pulled out of the uprights against the spring force of the spring element and folded over the holding element. The restoring force of the spring element is designed such that in the transport position, ie when the holding element, unintentional folding away of the retaining element is not possible.

alternative to the embodiment described above, the joint comprise a standpipe fixedly arranged on the bottom plate, which is connected to the respective holding rod via a hinge joint is, wherein on the respective support rod or the standpipe a Sleeve arranged is, which pushed in the transport position on the hinge joint is. To fold down the respective holding element, the sleeves are on the support rods laterally displaced, preferably raised, and thereby the respective Joint released, so that the retaining element can be folded.

The The first subtask is solved with a system comprising at least one transport pallet described above and a mixing and packaging plant, which for the feeding of rolls a storage tank having, in front of the storage container an inclined plane such angeord net is that the roles of the standing on the inclined plane Roll in the transport pallet into the storage container.

For this the inclined plane must be suitable, the transport container, which aligned with its front end to the storage container to accommodate. The inclined plane can also by unilateral lifting the transport pallet be generated 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 the rollers by means of a sliding device from the transport pallet in the storage tank to press.

The second subtask is a method using a solved transport pallet described above, in which the transport pallet on one in front of the storage tank arranged inclined plane is turned off.

In a cheap one embodiment of the procedure is after stopping the transport pallet the inclined plane arranged on the transport pallet swiveling Locking element unlocked. After unlocking the locking mechanism the closure element oscillates in an open position and oscillates in the normal force direction, that is substantially perpendicular.

Preferably the rollers are stored on the transport pallet in such a way that the axial alignment of the rollers transversely to the direction of movement of the emptying process is selected. With such an orientation of the rollers parallel to the direction of travel the webbing of the mixing and packaging plant will be no further Devices or steps needed to align the rollers. According to the invention are the term paper rolls also all the same roles or rod-shaped products but in particular all paper and paperboard products.

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

To the better understanding The invention will be explained in more detail with reference to the following drawing figures. there show the:

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

2 a side view along the line AA in 1 ;

3 : a view according to 1 during the emptying process; and

4 a schematic side view of a transport pallet with folded front and rear retaining element.

5 an alternative embodiment analog 3 with attachment of the front holding element on the pallet foot.

6 the alternative embodiment of 5 in a folded position

In 1 is a side view of a transport pallet according to the invention 1 shown on the multilayer paper rolls 3 charged. Here are the lower paper rolls 3 on the bottom plate 5 on. A rolling of paper rolls 3 will be at the front end 6 and at the back end 7 the bottom plate 5 by one vertically on the bottom plate 5 towering front retaining element 9 or rear retaining element 8th prevented.

The front retaining element 9 includes a first front support bar 10 and one behind, in the view of 1 unrecognizable, second front retaining bar 11 (S. 2 ). Both front support bars 10 . 11 are over a crossbar 17 (see also 2 ) connected to a bracket.

At the crossbar 17 of the front retaining element 9 engages pivotally mounted a closure element 13 at. In the closed position shown development of the closure element 13 can the paper rolls 3 due to their comparatively small roll width 4 (S. 2 ) between the two front support rods 10 . 11 partially pass and lie on the closure element 13 at.

The closure element 13 remains alone due to its inertial mass in the closed position shown. However, especially during transportation of the transport pallet 1 , unintentional opening of the closure element 13 To effectively prevent is in the range of the cross bar 17 on the closure element 13 a locking mechanism 18 arranged. This is designed as a spring-loaded bolt in the bearing bush 13a of the closure element 13 held and locked in the closed position in a complementary formed bore of the crossbar 17 one. To unlock the locking mechanism 18 pulled out in its axial direction against the spring force, so that the closure element 13 can swing like a flap in an open position. In an alternative embodiment (not shown in detail), the closure element 13 by means of one on the bottom plate 5 possibly also on the transverse boards arranged locking element ( 18a )) against unintentional swinging or opening. 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 the closed position an opening (swinging) of the closure element 13 ,

The rear retaining element 8th is located at the rear end 7 the transport pallet 1 and also includes first and second rear support bars 14 . 15 (S. 2 ). Both rear support rods 14 . 15 are also by means of a cross bar 17 connected in their upper end. The main difference between the rear retaining element 8th and the front retaining element 9 is that the distance 16 (S. 2 ) of the rear support rods 14 . 15 less is chosen than the roll width 4 (S. 2 ), so the paper rolls 3 immediately at the support rods 14 . 15 come to the plant. Rolling the paper rolls 3 between the rear support rods 14 . 15 can not.

For convenient handling is the transport pallet 1 with a front foot 27a and a rear stand 27b fitted.

The width ratios between the two holding elements 8th . 9 and the roll width 4 the paper rolls 3 will be especially good in the opposite 1 90 ° rotated view of the 2 clear.

The front support rods 10 . 11 have a greater distance 12 on as the roll width 4 the paper rolls 3 , A rolling of paper rolls 3 between the front support rods 10 . 11 out of the picture plane is only by the closure element 13 prevented. The first and second rear stay bars 14 . 15 are mostly through the paper rolls 3 covered. The distance 16 the rear support rods 14 . 15 is chosen much smaller than the roll width 4 the paper rolls 3 ,

In the 3 is the transport pallet 1 shown during the emptying process. The transport pallet 1 became on an incline 24 turned off and subsequently the locking mechanism 18 pressed, leaving the paper rolls 3 in the direction of movement 25 from the transport pallet 1 through the front retaining element 9 roll it through. A stationary on the inclined plane 24 arranged stopper 28 Prevents form-fitting 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 the mixing and packaging plant 2 , The orientation of the paper rolls 3 inside the storage container 23 agrees with the orientation of the paper rolls 3 on the transport pallet 1 match. A subsequent correction of the orientation of the transport pallet 1 roll out paper rolls 3 takes over the closure element 13 ,

The 4 shows a transport pallet 1 after the emptying process, ie without paper rolls 3 , To reduce the storage space, both the front retaining element 9 as well as the rear retaining element 8th folded. Both retaining elements 8th . 9 are now almost parallel to the bottom plate 5 aligned and preferably do not protrude over the bottom plate 5 out. The folding over of the two holding elements 8th . 9 is about joints 19 realized. Here is the bottom plate 5 expediently worked out so that the holding elements 9 . 8th lie in folded form more or less flush on the bottom plate.

In the in 4 shown embodiment of the transport pallet 1 is the front holding element 9 and the rear retaining element 8th exemplary with different joints 19 executed, wherein preferably the front and / or optionally also the rear retaining element 8th . 9 with the joint 19 swiveling on the pallet foot 27a are attached. Usually, the transport pallets 1 with similar joints 19 manufactured.

The joint 19 at the front end 6 the bottom plate 5 allows folding of the front retaining element 9 , Starting from the transport position with stationary holding element 9 is the whole retaining element 9 held so that it is on the plate 5 can be tilted or swung. 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 bar 10 . 11 of which only the first front retaining bar 10 is visible, and the standpipe 20 is solved. Subsequently, the front retaining element 9 be transferred. In this lying position is the front retaining element 9 with the outer wall of the bearing bush 13a of the closure element 13 on the bottom plate 5 on while the opposite end of the closure element 13 from the spring element 21 is held. The spring element 21 represents in the folded position primarily a loss of security of the retaining element 9 dar. To set up the front retaining element 9 in the transport position, the holding element 9 raised and the support rods 10 . 11 in the respective standpipe 20 plugged. The exact match is made by the restoring force of the spring element 21 supported. In the version with hinge 19 becomes the retaining element 9 held by a corresponding stop on the hinge in a vertical position.

The joint 19 at the far end 7 the bottom plate 5 gives way to the joint constructively 19 at the front end 6 from. In one embodiment, the rear support rods 14 . 15 the rear retaining element 8th are permanently on each a pull-out protection or via a hinge joint 26 with the standpipe 20 connected. In the transport position, the safety catch in the standpipe 20 sinks or becomes the hinge joint 26 blocked. This is done on the respective rear support bar 14 . 15 slidably arranged sleeve 22 in the transport position via the hinge joint 26 is pushed. To fold down the rear retaining element 8th become the support rods 14 . 15 lifted and pulled out of the standpipe or are in the alternative embodiment, both sleeves 22 , recognizable in 4 only the sleeve 22 of the first rear stay 14 , raised and the rear retaining element 8th will be allocated. A loss of security is not required in this embodiment, since the rear standpipes 20 via the safety catch or via the hinge joint 26 steadily with the rear retaining element 8th keep in touch.
