Description

The invention relates to a device for stacking flat, rectangular bodies, especially pallet frames.

Industry, trade and in particular logistics companies usually use pallets for the storage and transport of goods. In order to secure the goods on the pallets against slipping sideways, it is known to use a mounting frame as a limitation. Such mounting frames are used, for example, in German utility models DE 93 02 029 described.

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

In order to store and transport the frame, it is also advisable to stack the frame. In the German Offenlegungsschrift DE 42 40 882 For example, a stacking frame for pallets with a mounting frame is described, which is intended to prevent pallets with frames from slipping sideways within the stack.

In connection with stacking various pallet stacking devices are also known, where a stack of pallets is formed from below by that the respective new pallet by lifting an already formed stack is introduced in this as the lowest pallet. Such devices offer the advantage, for example, that the pallets are at a low Feed height and can also be seen again. For such embodiments For example, lifting devices, grippers and / or separating devices used which raise the stacks.

The pallet stacking devices with grippers and usable lifting device include, for example, the one in the German utility model DE 201 04 585 Pallet stacking device described, in which the pallets are inserted at the bottom of the stack. When a pallet is inserted, the pallet stack is raised.

Devices are also known for stacking pallets which align a stack of pallets on a frame specially shaped for this purpose and thus lead to pallets stacked one on top of the other. The German Offenlegungsschrift DE 100 20 475 describes, for example, a pallet stack straightener that stacks pallets in straight stacks without mechanical intervention. For this purpose, the device has a funnel-shaped introduction in the upper region, into which the pallets are stacked vertically one above the other when the stacker is let in.

The object of the invention is a To provide a device for stacking stacking frames for pallets, which enables the stacks formed to be transported easily and securely, the frame being folded into flat and rectangular bodies are.

According to the invention, this object solved, that a device for stacking flat, rectangular bodies, in particular of folded frame for Pallets, at least three flat Elements consists of a box-shaped frame with a bottom part and form at least two side parts, the side parts via one common connecting edge at an angle to each other. there has at least one side part at least one recess, the from the bottom part essentially parallel to the connecting edge of the Side parts run upwards.

In a particularly preferred embodiment of the invention, the device has means for attaching a lifting and / or transport device. The funds are preferably on Bottom part of the device, they can but also be attached to the side panels. By means The device can be used to attach a lifting and / or transport device with or without stacking frame to different locations and storage locations be transported.

In the device designed in this way can be as Insert the base plate of a stack onto a pallet on which folded stacking frame on top of each other stack it. The stacking frames are stacked 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 Fixierband be strapped. The bands are expedient around the bottom pallet and the stack. So the palette can be transported and stored together with the stack.

Other advantages, special features and appropriate further training the invention result from the dependent claims and the following Representation of preferred embodiments based on the illustrations.

The illustrations show:

1 a first particularly preferred embodiment of a device for stacking folded mounting frames; and

2 a further embodiment for a device for stacking folded mounting frames.

In 1 shows a particularly preferred embodiment of the device according to the invention for stacking flat, rectangular bodies, in particular of folded mounting frames, in which the device is formed from at least three flat elements. To form such a box-shaped frame with a Bo denteil 10 and two adjacent side panels 20 and 30 these three elements are sufficient. If this is appropriate, however, a third side part can also be provided. A third side part increases the stability of the device, but limits the possibilities of inserting mounting frames, since only one direction of access remains.

The flat elements of the frame can can be formed in different ways. It can be, for example are plates, grids and / or braids. The elements expediently exist Made of materials that have the required rigidity of the device guarantee. plates made of sheet metal offer high stability, but lead to a too high one Device weight. Therefore, plastic plates or other materials for some areas of application more suitable.

By using grids and braids the weight can be significantly reduced. there have to For example, grids can be designed so that the device receives sufficient rigidity. To form the grid For example, bars and / or pipes come from different materials into consideration.

Braids can be strained, for example Fabric and Strips of fabric are formed, stretched between frame parts be what the basic body form the device. For example, the frame could be Rods or sheets are formed, the sides and where appropriate also the floor area can be covered with fabric strips to reduce weight.

The flat elements are expediently put together in such a way that the side parts 20 and 30 on a common connecting edge 60 form an angle of essentially 90 °. An angle of 90 ° is expedient for a good alignment of the mounting frames, but this can also include angles of the order of 85 ° to 95 °. Folded mounting frames can be introduced into the box-shaped frame thus formed, stacked one above the other and thereby aligned with the side parts of the device, so that a stack with mounting frames lying exactly one above the other can be formed.

In order to transport a stack of flat bodies easily and safely, these stacks are usually strapped with fixing straps made of plastic or other materials. In order to attach such fixing tapes to a stack of stacking frames formed with the device, the device according to the invention has at least one recess in at least one side part, which is essentially parallel to the connecting edge from the bottom part 10 60 runs upwards. The term “essentially” also includes courses that are up to 10 ° parallel to the connecting edge 60 differ. It is particularly advantageous if a side part has two elongate cutouts and the stack can be strapped with two fixing straps.

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

The means for attaching a lifting and / or transport device to the bottom part 10 the device are in a particularly preferred embodiment of the invention through an elongated opening 70 and at least one overlying U-shaped angle profile 80 educated. For example, the lifting fork of a pallet truck can go into the bottom part 10 under the angle profiles 80 be pushed while the device is standing on a surface.

If a base pallet is to be used for stacking the mounting frames, it is expedient to enable the introduction of this first base pallet into the device in that the angle piece 82 is executed split. This is in the drawing of the 2 shown in a further particularly preferred embodiment. Two U-shaped angle profiles are expediently used 81 and 82 used at the beginning and end of each elongated opening. So the floor pallet can cross the elongated openings 70 be introduced with a pallet truck, the load-bearing fork of the pallet truck with the pallet between the two angle profiles 81 and 82 can be pushed. The pallet can be placed between the angle profiles. In a further possible embodiment, however, 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.

As a means of lifting and transporting the Device can other embodiments in the bottom part be provided by lifting devices. This includes, for example, the possibility of Bottom part to be provided with support feet underneath, which the Lift the device off a surface, so that a lifting device can be moved under the device can.

An example of handling the device according to the invention is described below. The stacking aid according to the invention for pallet mounting frames is transported to the desired work location, for example with a pallet truck, an electric lifting device or a forklift. For this purpose, the load suspension fork of the transport device is inserted into the openings 70 retracted, the entire device on the angle profiles 81 and 82 raised and brought to the site.

A pallet is placed between the angle profiles to start work 81 and 82 in the bottom part 10 inserted. Make sure that the pallet lies against the side parts. The folded mounting frames to be stacked are now inserted into the device. To form a stable stack, it has proven to be expedient to insert a few 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 use the one with the cutouts 40 and 50 interrupted side 20 of the stack, for example, are strapped with plastic straps. Once this has been done, a lifting device is pushed under the pallet and the stack with the pallet is lifted out of the stacking aid. The next stack can then be formed.
