Description

The The present invention relates to a pallet of corrugated cardboard with a Support plate made of single or multiple corrugated cardboard or in the form of a honeycomb panel or a combination of these corrugated boards and with attached to the underside of the carrier plate Pallet feet.

Such pallets are intended to replace pallets of wood and / or plastic. They are lighter than wooden pallets and can be recycled. From the French patent application FR-2 936 231 A a pallet of corrugated board is known with the features of the preamble of claim 1. This range of corrugated cardboard has a very complicated structure by the provision of a variety of stiffening walls and struts. The production of such a pallet of corrugated cardboard is time consuming and complicated.

Of the present invention is the object of a pallet Made of corrugated cardboard, which is simple and inexpensive is easy to handle and easy to recycle or can be disposed of.

These Task is using a pallet of corrugated cardboard with the characteristics of Claim 1 solved.

under claims are features of preferred embodiments of the present invention Directed invention.

in the The invention will be described below with reference to the description of an embodiment explained in more detail with reference to the drawing. Show:

1a -F a plan view of a support plate with not yet folded Aufrichtklappen and a view of the front side of the support plate with three alternative bends;

2a -B building a pallet of corrugated board according to the invention;

3a , b is a plan view of a second embodiment of a carrier plate and various carrier feet; and

4a -C the packaging of a Packgutstücks on the pallet according to the invention with a master carton or with a wrapper.

1a shows a carrier plate 1 an embodiment of the pallet of corrugated cardboard according to the invention in plan view. The used corrugated cardboard can, as with 5 is shown to have a corrugation parallel to the V-cuts 4 or to grooves ( 1c . 1d ) or perpendicular thereto. The V-cuts 4 have, how to get in 1b in the front view of the carrier plate 1 best recognizes an opening angle of about 90 °. The opening angle α may possibly also be slightly greater than 90 °, but it should not be smaller, as a result, the vertical erection of Aufrichtklappen 3 is prevented.

1c shows an alternative to the V-cuts 4 , This is a groove 4a introduced with vertical walls in the corrugated cardboard whose width is substantially the height of the support plate 1 equivalent. The bottom of the groove 4a can consist of a single layer of corrugated cardboard. The Aufrichtklappen 3 become the support plate 1 towards the lower edge of the groove 4a folded up and then glued.

In the 1d The variant shown follows the same principle as the alternative according to 1c instead of the corrugated cardboard layer left standing, the erecting flaps 3 from the carrier plate 1 cut off and a tape 10 So it is at the bottom of the carrier plate 1 and the Aufrichtklappen 3 attached, that the width of the groove in turn corresponds to the height of the support plate. This variant has the advantage of easier production of the groove by simply cutting off the erection plates 3 from the carrier plate 1 instead of a Frässvorgangs. At the same time takes place when erecting the Aufrichtklappen 3 already a gluing of the adhesive tape 10 on the side edge of the carrier plate 1 instead of.

The Aufrichtklappen 3 are in this embodiment on two opposite sides of the carrier plate 1 arranged. On the Aufrichtklappen 3 are adhesive strips 6 attached, which can be covered with removable cover strip of release paper or silicone paper, as long as the adhesive strips for attaching the Aufrichtklappen 3 not yet needed on a piece of transport goods. It can also be adhesive tracks or double-sided adhesive tape can be used.

As another variant, the Aufrichtklappen 3 already at the production in the V-section 4 or in the groove 4a provided with adhesive and erected (see 1e ). The U-profile thus formed then serves as a carrier shell, in which then a piece of transport goods can be inserted or placed or placed. The attachment of Transportgutstücks on the loading carrier can be done by means of a strapping.

1f ) shows a variant in which the Aufrichtklappen 3 folded down. In the embodiment shown are each three feet 2 mitein a cross bar at its upper end connected. A side wall of the cross bar is provided with adhesive and also on top of the cross bar adhesive is applied.

Then the feet become 2 over the crossbar with the underside of the carrier plate 1 and at the edges also with the Aufrichtklappen 3 firmly glued. This creates a very rigid and rigid pallet, which, depending on the size and weight of Transportgutstücks, can also be placed in a high bay. The number and dimensions of the feet 2 depend on the transport item.

2 shows the assembly of the pallet made of corrugated cardboard according to the invention. In 2a The first step is shown in which the pallet feet 2 on the carrier plate 1 be attached attached. This can be done by gluing or stapling. The pallet feet are also made of corrugated blocks, with their corrugation perpendicular to the surface of the support plate 1 extends to give the pallet feet sufficient strength in the direction of the application of force by a piece of transport goods.

How to get in 2 B sees, becomes a carton 8th or a piece of transport goods 7 on the carrier plate 1 put on and then the Aufrichtklappen 3 folded up. Are any existing paper strips over the adhesive strip 6 removed, the Aufrichtklappen 3 against the carton 8th or the piece of transport goods 7 pressed on and attached to this.

3a shows an embodiment of a carrier plate 1 , at the Aufrichtklappen 3 attached to each side. This allows the stiffening effect of Aufrichtklappen 3 still increase. Further one sees in 3a dot-dashed two different types of pallet feet 2a . 2 B , The pallet feet 2a extend over the entire length of one side and are on opposite sides of the carrier plate 1 whereas cube-shaped pallet feet 2 B in each corner of the support plate, so a total of 4 pieces are arranged. This makes it possible to drive under the load carriers from all four sides. The number and shape of the feet should be selected according to the size and weight of the item to be transported.

3b shows two variants of support feet. On the left is a support foot pictured over its entire surface with a moisture-resistant material 11 is sheathed. On the right is a version shown in which the foot is only in a shell 12 made of moisture-resistant material. The shell is glued to the foot.

The pallet feet can be separated from the carrier plate by the customer 1 be delivered, which saves a lot of space when transporting the pallet made of corrugated cardboard according to the invention. The customer attaches the pallet feet 2 then even by gluing or adhering to the underside of the carrier plate 1 ,

The proportions of the carrier plates shown here are not intended to be limiting. Thus, carrier plates for long goods with a length of more than 7 m can be produced. The folded upright flaps 3 ensure the necessary flexural rigidity of the pallet with every dimensioning. By attaching Aufrichtklappen on all sides of the carrier plate 1 the flexural rigidity can be further increased.

For carrier plates 1 small thickness can be the V-cut 4 be replaced by a simple grooving, since in this case the restoring forces of the corrugated cardboard are lower. The grooving is produced by simply pressing in the corrugated cardboard at the location of the grooving with a suitable seaming tool.

4 finally shows a packaging process of a transport item 8th , The transport item 8th is on the carrier plate 1 the pallet made of corrugated cardboard and a carton 7 suitable size is about the transport item 8th slipped. Subsequently, the Aufrichtklappen 3 with their adhesive strips 6 against the carton 7 pressed by being folded up. Above the top edge of the erecting flaps 3 runs in all sidewalls of the outer carton 7 a perforation 9 , This can at the destination of the transport item 8th be torn open so as to open the packaging.

Alternatively, the transport item 8th can also be transported without a carton, with the Aufrichtklappen 3 attached directly to the side walls of the transport piece. The transport item can also be protected by a shrink-on film, so that the Aufrichtklappen 3 attached to the shrink-on film. Instead of the Aufrichtklappen 3 To glue, they can also be kept in an upright position with straps that embrace the pallet and the transport piece. Finally, a stapling to a carton is conceivable. Instead of self-adhesive, it is also possible to use a hot-melt adhesive which is applied at the place of packaging.

The pallet made of corrugated cardboard according to the invention is ideal for air freight due to its low weight. Also, the pallet of corrugated board for hygiene reasons against wood is advantageous in the transport of food. The production of the corrugated board according to the invention can be easily automated due to their simple structure, which the manufacturer enormously accelerated.

Finally, the disposal of the pallet and packaging, ie usually the outer carton 7 , simplified because they are the same materials. Finally, the corrugated board according to the invention is IPPC-compliant (standard for non-wood packaging) and complies with the IPPC-ISTN 15 classification.
