Description

Description of the invention

The subject of the invention is a device for stacking pallet-mounted frames, in particular for stacking flat rectangular elements.

Industry and commerce, and logistics companies in particular, typically use pallets to store and transport goods. In order to protect the goods on pallets against their lateral displacement, it is known to use flange-mounted frames limiting this displacement, which are described in the German utility model DE 9302029.

In order to be able to store and transport such flange mounted frames in a space-saving manner, these devices are preferably configured to be folded into flat rectangular elements, as disclosed in European patent EP0825954, in which a foldable quadrilateral frame is described.

In addition, when storing and transporting flange mount frames, stacking is used, as is described in the German preliminary patent application DE 4240882, which discloses a stacking frame for a pallet with a stacking frame preventing lateral displacement of the pallets with the frame.

Various devices for stacking empty pallets are also known in which the stack of pallets is formed from below in that each new pallet is stacked as a bottom pallet by lifting the stack already formed. The advantage of these devices is that the pallets can be inserted and removed at a low height by means of, for example, lifting mechanisms, grippers and / or separating devices which lift the stacks of pallets.

For example, devices for stacking pallets with grippers and a lifting device put into operation include the pallet stacker described in the German utility model DE 20104585, in which the pallets are stacked from below, the stack of pallets being lifted when the pallet is introduced.

Furthermore, devices for stacking pallets are known, which align and align a stack of pallets to a frame specially designed for this purpose, and thus reduce the pallets to a simple stacking on top of each other. The German preliminary patent DE 10020475 describes a pallet positioning device which steers pallets in straight stacks without the need for additional mechanical action. For this purpose, the device has a funnel opening in the upper area, into which the pallets are placed on top of each other by the vertical stacker from above.

Display and display containers for the presentation of flat objects are also known. For example, the German utility model DE 8809364U1 describes a folding box made of cardboard (cardboard) or corrugated cardboard as a display container. This collapsible container has at least one open side for receiving several items in a stack and is shaped such that it can be stacked straight, without special tools, and is a very stable structure. The structure of this box allows the most advantageous use of the material, in particular through a bottom plate separated from its body.

Swiss Patent CH-A-486871 describes a device having a rectangular section glass for receiving paper, having four side walls attached to a base element. Fastening means are attached near the symmetry axis of the upper edges of these walls, making it possible, before the shaft is filled with paper, to lightly detach the two rope members tied by crossing them through the base member near their ends. A stack of paper stacked in the glass of the device can be tied with these string elements.

In turn, the German description of utility model DE-U-22920258 discloses a box-shaped device for folding and binding old newspapers and magazines having a cross-shaped continuous groove at its bottom. In one embodiment of this box, its side walls have a slot open in the center and directed from the bottom upwards.

Also known from the French patent application FR 2 690 325 is a plastic container for collecting objects, in particular paper, logs and surveys intended for recycling and for making packages. This container is characterized by the fact that its side walls are equipped with devices enabling, during filling, the ends of the ligament to be held and facilitating the joining of the ends of the ligament at the moment of making the bundle.

On the other hand, the container for disposal of old paper with a lacing device, known from the German description of utility model DE 20004017, is characterized by the fact that before starting the stacking process, a string is placed in a certain way on the bottom of the container, larger than the one given in him in a pile of old paper. After filling this container, it is easy to tie a stack of paper into it and remove it from it.

The object of the invention is to provide a device structure for stacking pallet top-frames, which ensures simple and reliable transport of the stacks formed, in which the top-mounted frames are folded into flat rectangular structures.

According to the invention, this object is achieved in that the device for stacking flat rectangular structures, in particular complex pallet-mounted frames, provided with means for attaching / positioning the lifting and / or transport device consists of at least three planar elements. forming a box-frame with a bottom part and at least two side parts, the side parts being angled towards each other with a common joining edge and that at least one side part has at least one recess for receiving retaining strips on a stack of plug-on frames formed in this device, the recess extending from the bottom portion upwardly substantially parallel to the edge joining the two side portions. It is preferred that the angle formed at the joining edge by the side walls is in the range 85 ° to 95 ° and the plane elements are plates, grids and / or braids, or the plane elements are made of sheets, pipes, rods, strips and / or tapes. It is also advantageous if the means for attaching / locating the lifting and / or transport device are located in the bottom part of the device. It is also advantageous if the means for attaching / locating the lifting and / or transport device situated in the bottom part consist of two elongated holes and U-angles situated above them, or consist of two elongated holes and U-angles at the beginning and end of each out of these holes. It is also advantageous if the side part has two rebates extending from the bottom part upwards substantially parallel to the edge joining the side walls.

In an optimal embodiment of the invention, the device has means for placing the lifting or transporting device, which are optimally arranged on the bottom part thereof, but can also be arranged on the side parts, which means are used to transport the device with or without stacks of pallet frames. , in various places of use or storage.

In the embodiment of the device described below, a pallet can be inserted at a specific location as a base plate of a stack of pallets, on which folded stacked frames can be stored. When stacked, the pallet top frames are aligned on the box frame. In order to fix the finished pile, it can be wrapped with at least one securing strip starting from the recessed side part, then it is advantageous to wrap the strips around the base plate and the pile. The pallet secured in this way can be transported and stored together with the stack.

The subject matter of the invention is shown in an embodiment in the drawing, in which Fig. 1 shows a perspective view of a first particularly preferred embodiment of the device, in which the means for attaching or placing the lifting and / or transport device arranged in its bottom part consists of two openings longitudinal and opposite U-angles, and fig. 2 - a second version of the implementation of the same device in perspective view, in which the means for attaching or placing the lifting and / or transport device located in its bottom part consists of two elongated holes and angles channels located at the beginning and end of each of these openings.

A particularly preferred embodiment of the device for stacking flat rectangular structures, in particular the composite pallet top frames shown in Fig. 1, comprises at least three flat elements, making it possible to form a box frame with a bottom part 10 and two adjacent sides 20 and 30. These flat elements can be shaped in various ways, for example they can be plates, grids and / or braided structures, and these elements are optimally made of materials ensuring adequate rigidity of the device. The sheets made of sheet metal ensure great stability but at the same time increase the weight of the device. Consequently, plates made of plastic or other materials are better suited to many fields of application. Also, the use of lattice elements and woven structures to make these plates makes it possible to significantly reduce the weight of the device, and the grids must be configured in such a way that the device obtains sufficient stiffness, so that rods and / or tubes made of different materials are preferably used for their production. materials.

In turn, the braided constructions can be made of strip or tape elements stretched between the frame sections that form the basic structure of the device. Such a frame can also be formed, for example, of pipes, rods or metal sheets, its sides and optional

The bottom plate is trimmed with tape in order to reduce its weight. The flat elements are preferably connected to each other in such a way that the side parts 20 and 30 form an angle of substantially 90 ° at their common joining edge 60, this angle may preferably be from 85 ° to 95 ° for a good alignment of the add-on frames. The folded pallet stacking frames can be placed on top of each other in the box thus formed and then aligned with the side portions of the device so as to form a stack of stacked frames exactly one on top of the other.

In order that stacks of flat elements can be transported easily and reliably, they are usually first strapped with retaining straps made of plastic or some other material. For this purpose, the device according to the invention has at least one recess in at least one side wall extending from the bottom portion 10 and extending upwardly substantially parallel to the connecting edge 60, the term "substantially also including waveforms deviating by about 10 °. from parallel to the edge joining the side parts 20 and 30. It is particularly advantageous if the side parts 20 and 30 have two longitudinal recesses and the stack may be girdled with two securing strips.

It has also turned out to be advantageous for the device to have means for accommodating the lifting device and / or transporting it. In the most advantageous embodiment of the invention, these means are located in the lower part 10 of the device, and they can also be mounted on the side parts 20 and 30 or can be integrated therewith. Such means may be, for example, holes, hooks or other hooking means. In the most preferred embodiment of the invention, the means for arranging the lifting and / or transporting mechanism are provided on the bottom part 10 of the device, each formed by an elongated opening 70 and at least one U-angle 80 located above this opening. The forks of the lift truck can then be pushed into the bottom part 10 under the U-profile 80 while the device is standing on the surface.

On the other hand, when a base pallet is used to stack the stacked frames, it is preferable to place this first base pallet in a device in which the angle section 83 is configured as divided, as shown in figure 2 in a second optimal embodiment. devices. In this case, two C-angles 81 and 82 are here preferably placed at the beginning and end of each elongated opening 70. Thus, the base pallet can be positioned transversely to the longitudinal holes 70 by means of a lift truck, the load-bearing forks of which can be inserted with the pallet between the angles. C-sections 81 and 82, the pallet also being able to be lowered between the angles. In another possible version of the implementation, the height of these angles may be selected in such a way that a pallet can be placed over them without interfering with each other.

Other versions of the lifting members can also be used as means for lifting and transporting the device arranged in the bottom part, which can be realized by equipping the bottom part with support feet underneath, enabling the device to be lifted above the surface so that the lifting device can run underneath the device. . The operating principle of the device according to the invention is as follows:

The stacking device for the pallet frames is transported, for example, by a lift truck, an electric lifting mechanism or a forklift to the desired location. To this end, the carrying forks of the transport mechanism are inserted into the openings 70, and the entire device is lifted on the angles 81 and 82 and carried to the place of use. To start the process, the pallet is inserted between the angles 81 and 82 in the lower part 10, taking care that the pallet rests against the side parts. The pallet top frames that are folded up and are to be stacked are then inserted into the device. To ensure a stable stack, it has proven advantageous to align several layers in one direction and then further layers in a direction perpendicular to the previous orientation. After the stacking is complete, it is wrapped with e.g. plastic straps from the side portion 20, which is interrupted by recesses 40 and 50, then the lifting mechanism is slid under the pallet and the stack with the pallet is lifted from the stacking aid, and then a new stack is created if necessary.
