Description

The The invention relates to a device for stacking flat, rectangular bodies in particular of pallet placement frames.

Industry, trade and especially logistics companies usually use pallets for the storage and transport of goods. In order to secure the goods on the pallets against lateral slippage, it is known to use Aufsetzrahmen as a boundary. Such Aufsetzrahmen be, for example, in the German utility model DE 93 02 029 described.

In order to store and transport such Aufsetzrahmen space-saving as possible, the corresponding devices are expediently designed foldable, so that they can be folded to flat, rectangular bodies together. Such an embodiment is for example in the European patent specification EP 0 825 954 discloses a foldable, four-sided frame is described.

To store Aufsetzrahmen and transport, it is also appropriate to stack the Aufsetzrahmen. In the German publication DE 42 40 882 For example, a stacking frame for pallets with Aufsetzrahmen is described, which is to prevent lateral slippage of pallets with frame within stacks.

In Connection with the stacking of empty pallets are also different Pallet Stackers known in which the formation of a pallet stack from below by done that each new pallet by lifting one already formed stack in this is introduced as the lowest range. such For example, devices offer the advantage that the pallets at a low altitude supply and also to be taken again. For such embodiments For example, lifting devices, grippers and / or separating devices used lifting the stacks.

To the pallet stacking devices with grippers and usable lifting device, for example, counts in the German utility model DE 201 04 585 described pallet stacker, in which the pallets are inserted at the bottom of the stack. When you insert a pallet, the pallet stack is raised.

For stacking pallets devices are also known which align a pallet stack on a specially shaped frame and thus lead to just stacked pallets. The German Offenlegungsschrift DE 100 20 475 describes, for example, a pallet stack straightener that stacks pallets in straight stacks without machine intervention. The device has for this purpose in the upper part of a funnel-shaped introduction, in which the pallets are vertically stacked on top of each other when entering the stacker from above.

For offering flat objects display containers are also known. For example, the German utility model describes DE 88 09 364 U1 a carton made of cardboard, corrugated cardboard or the like as a display container. The container has at least one open side for receiving a plurality of stacked objects. The carton is designed so that it is easy to erect without additional tools and represents a stable box as possible. It should also be achieved as good as possible material utilization. This is achieved in particular by a separate from the hull bottom plate.

task The invention is an apparatus for stacking Aufsetzrahmen to provide for pallets, which allows easy and safe transport of the stack formed, wherein the Aufsetzrahmen folded into flat and rectangular bodies are.

According to the invention this Task solved with the features of claims 1.

In a particularly preferred embodiment According to the invention, the device has means for applying a lifting and / or transport on. The funds are preferably located at Bottom part of the device, they can but also be attached to the side panels. By the means for attaching a lifting and / or transport device, the device with or without Aufsetzrahmenstapel to various use and storage locations be transported.

In the so executed Device leaves to bring a base as a base plate of a stack on which can be stacked Aufsetzrahmen stacked. The Aufsetzrahmen be when stacking on the box-shaped frame aligned. To fix a finished stack, you can he from the side part with the recess with at least one Strapping band are strapped. The bands will be expediently pulled around the bottom pallet and the stack. That's how the palette works transported and stored together with the stack.

Further Advantages, special features and expedient developments of the invention emerge from the dependent claims and the following description of preferred embodiments based on the pictures.

From the pictures shows:

1 a first particularly preferred embodiment of an apparatus for stacking folded Aufsetzrahmen; and

2 a further embodiment of an apparatus for stacking folded Aufsetzrahmen.

In 1 is a particularly preferred embodiment of the device according to the invention for stacking flat, rectangular bodies, in particular of folded Aufsetzrahmen shown, in which the device is formed of at least three flat elements. To form such a box-shaped frame with a bottom part 10 and two adjacent side panels 20 and 30 These three elements are enough. If this is expedient, however, a third side part can also be provided. A third side part increases the stability of the device, but limits the possibilities of introducing Aufsetzrahmen, since only one access direction remains.

The flat Elements of the frame can be formed in different ways. This can be for example to act plates, grid and / or braids. The elements are expediently made of materials which the required rigidity of the device guarantee. plates Made of sheet metal offer high stability, but lead to too high Weight of the device. Therefore, plates are made of plastics or other materials for some application areas more suitable.

By The use of meshes and braids can increase the weight considerably be reduced. It must For example, grating be designed so that the device obtains sufficient rigidity. To form the grid For example, rods and / or tubes come from different materials into consideration.

braids can be formed for example by stretched fabric and fabric strips, be stretched between frame parts, which is the main body of the Form device. The frame could be formed for example by pipes, rods or sheets, the sides and possibly also the bottom surface to the Weight reduction be covered with strips of fabric.

The sheet-like elements are expediently joined together so that the side parts 20 and 30 at a common connecting edge 60 form an angle of substantially 90 °. For a good alignment of the Aufsetzrahmen an angle of 90 ° is appropriate, but this may also include angles in the order of 85 ° to 95 °. In the thus formed box-shaped frame folded Aufsetzrahmen can be introduced, stacked on top of each other and thereby aligned with the side panels of the device, so that it can form a stack with exactly superimposed Aufsetzrahmen.

To transport a stack of flat bodies easily and safely, these stacks are usually strapped with plastic straps or other materials. In order to attach such fixing straps to a Aufsetzrahmenstapel formed with the device, the device according to the invention in at least one side part at least one recess, which from the bottom part 10 essentially parallel to the connecting edge 60 goes up. In this case, the term "substantially" also includes courses that are up to 10 ° from a parallelism to the connecting edge 60 differ. It is particularly advantageous if one side part has two elongate recesses, and the stack can be strapped with two fixing straps in this way.

It has also proven to be expedient that the device has means for applying a lifting and / or transport device. These means are in a particularly preferred embodiment of the invention in the bottom part 10 the device. However, you can also look at the side panels 20 and 30 be attached or integrated into this. In this example, openings, hooks or other interventional devices come into consideration.

The means for applying a lifting and / or transport device on the bottom part 10 The device are in a particularly preferred embodiment of the invention by a respective elongated opening 70 and at least one overlying U-shaped angle profile 80 educated. Thus, the load-carrying fork of a lift truck in the bottom part 10 under the angle profiles 80 while the device is standing on a surface.

If a basic pallet is to be used for stacking the attachment frames, it is expedient to allow the introduction of this first base pallet into the device in that the angle piece 82 is executed shared. This is in the drawing of 2 shown in a further particularly preferred embodiment. It who the expediently two U-shaped angle profiles 81 and 82 used at the beginning and at the end of each elongated opening. So the floor pallet can cross the elongated openings 70 be introduced with a pallet truck, with the load-carrying fork of the lift truck with the pallet between the two angle sections 81 and 82 push. The pallet can be placed between the angle profiles. However, in another possible embodiment, the height of the angle profiles can also be selected such that the pallet can be set down over the angle profiles without being obstructed by the angle profiles.

When Means for lifting and transporting the device can in Bottom part also other embodiments be provided by lifting devices. This includes, for example, the possibility that Floor part to provide with underlying support feet, which the Lift device off a surface, so that a lifting device are driven under the device can.

An exemplary handling of the device according to the invention will be described below. The stacking aid according to the invention for pallet Aufsetzrahmen is transported, for example, with a pallet truck, a Elektrohubgerät or a forklift to the desired location. For this purpose, the load-receiving fork of the transport device in the openings 70 retracted, the entire device to the angle profiles 81 and 82 lifted and spent at the site.

To take up work, a pallet is inserted between the angle profiles 81 and 82 in the bottom part 10 inserted. Make sure that the pallet rests against the side panels. The folded and stacked Aufsetzrahmen are now introduced into the device. To form a stable stack, it has proven expedient to introduce some layers in one direction and to stack further layers at a right angle to the previous direction of insertion. When the stack is complete, you can start with the cutouts 40 and 50 interrupted page 20 the stack, for example, strapped with plastic straps. When this is done, a lifting device is pushed under the pallet and the stack with the pallet is lifted out of the stacking aid. Thereafter, the formation of the next batch can take place.
