Abstract

A wooden pallet (2) is employed for the transport and storage of sausage, meat and other food products in accordance with EU regulations. The pallet (2) is entirely enclosed within a weld-sealed plastic shell, from which it is separated by a gap of between 0.1 and 2 cm.

Description

The invention relates to a transport and storage device for transport and the storage of meat and sausage products subject to EC hygiene guidelines or food as well as various goods such as chemicals, property, equipment etc. with a wooden pallet with planks on crossbars existing loading area and with on the sides and in the middle below the loading area along running planks with feet.

Wooden pallets are usually different for transporting and storing Goods used. They are inexpensive and environmentally friendly. The disadvantage is that their Surface is not completely smooth. This leads to problems with different goods Hygiene requirements; These must not be stored on wooden pallets. Surrender too yourself cleaning problems. The material wood is uneven and therefore keeps it light Dirt tight. When it comes into contact with water, it sucks up. This leads to longer ones Drying times. Chips of the wood can come off, so there is a certain risk of injury consists. Chips can also be placed in the goods stored on the pallet or Penetrate packaging and damage it. Are chemicals stored or transported, they can seep into the wood if they accidentally emerge. If it is a slippery or even dangerous substance, the whole must Pallet unloaded and replaced. For these reasons, certain chemicals the use of wooden pallets is prohibited for safety reasons. The material Wood is also difficult to print on. An application of notices or advertisements is therefore difficult to do.

Existing hygiene guidelines for companies approved in the EC stipulate that Food such as B. meat and sausages only on plastic pallets in the factories may be stored. Plastic pallets cost DM 85 and are opposite Wooden pallets at a price of only DM 15, - relatively expensive.

Since inexpensive wooden pallets are not permitted, a large number of plastic pallets must be used be purchased, which ties up considerable capital. Still done the delivery of the goods mostly not on plastic pallets, as it is too complex, return the pallets to the supplier. But it is uneconomical for the supplier giving up the pallets, the plastic pallets are too expensive for that. As a consequence, the goods are still transported on wooden pallets and on site the goods have to be transferred from the wooden pallet to the plastic pallet in order to be able to store them hygienically in operation in accordance with the guidelines. The elaborate reloading of the goods from the wooden pallet to the plastic pallet is time-consuming and therefore expensive.

The plastic pallets used have to be cleaned with disinfectants become. This is also time and cost intensive.

A wooden pallet is also unsuitable for applying commercials. The material Wood makes this difficult. It is not possible to simply print a spot.

The object of the invention is to provide a transport and storage device for transporting and storage of different goods of the type mentioned above better printable and easier to clean and safer to design and transport and that Storage of meat and sausage products or foodstuffs subject to EC hygiene guidelines, to make it safer and more economical.

The object of the invention is achieved in that the one on the wooden pallet Wooden pallet completely surrounding envelope made of plastic film or material similar to plastic film is arranged close to the pallet.

This ensures that an inexpensive wooden pallet is used and the hygiene regulations are nevertheless used can be met for EC farms. The wooden pallet is covered in plastic film or material similar to plastic film.

It becomes washable and the clad wooden pallet is reusable. she is portable and can be moved by a forklift without compromising hygiene the goods or their environment is impaired. The wooden pallet is easy with To wrap or weld foil and easy to store.

It completely covers the area of application of a plastic pallet. Nevertheless, the in Foil clad wooden pallet inexpensive and has no relation to the cost of one expensive plastic pallet. The supplier is able to spot his sensitive and load and transport perishable goods onto the pallet covered with foil allow. The customer is not charged, does not have to go there and the one received Reload the goods onto a plastic pallet that complies with the hygiene regulations instead it is possible to load the loaded pallet directly into the pallet as it was delivered Spend operation and store there.

The expensive plastic pallets are saved and compared to the result Using the plastic pallets no disadvantages. The material of the cover, so Plastic film is inexpensive and the preparation of the cover can be done quickly and easily. Dressing the wooden pallet is also quick and can also be done on site respectively. The film can be easily cleaned and the wooden pallet clad with film can be used multiple times. A plastic film is also suitable for printing of commercials, which can mean additional money.

According to a special embodiment of the invention, the wooden pallet is in the casing tightly welded. The casing is preferably in the deep-drawing process or in Shrinking process arranged around the wooden pallet. This happens with all procedures Dressing the pallet quickly and easily.

According to a preferred embodiment of the invention, the shell is in the form of the outer contour the palette arranged, being the contour of the inner base edges and reshaped the underside of the crossbar. The pallet is packed hygienically and easy to clean.

It can still be picked up by a forklift without any problems because of the free space between the feet of the pallet. This is how the film is when it is transported not injured by the forklift. The almost right angle of the formation of the film around the inner edge of the stand also allows easy identification of the Pallet through a computer system with computer controlled storage.

According to a preferred embodiment of the invention, the casing has eight weld seams on, with the welds between the planks of the bed top and Connect the bottom of the case. The weld seams allow a particularly good one Forming the film between the feet of the pallet.

According to a preferred embodiment of the invention there are top and bottom the cover made of different film material and are coated differently. So it is possible to consider different needs for top and bottom, z. B. Non-slip for the bottom by a special non-slip Foil and bacterial protection for the top by a special antibacterial coating the slide.

This ensures that even if the film is easily damaged by carelessness the film around the pallet remains close to the pallet and not due to loss of negative pressure becomes tensionless and sags.

According to a special embodiment of the invention, the shell has a two small tabs on the front side of the pallet and in the area of a rear one A large engagement tab on the pallet side. This creates access areas to the pallet, that can be opened and closed as required.

According to a preferred embodiment of the invention, the large engagement tab has two vertical cuts along the outer edge of the stand and one vertical Cuts connecting horizontal section along an underside of the floor plank, the small engagement tabs at the front of the pallet between the The feet of the pallet run with each engagement tab two vertical cuts along the inner edges of the base and a horizontal cut connecting the vertical cuts along the bottom of the floor plank. So can quickly and a large entry opening for the forklift can be effortlessly opened. After this Transport process - by driving out the forklift - the opening falls from yourself too. It also ensures that the clad pallet from each side of the pallet can be loaded and transported.

According to a preferred embodiment of the invention, the distance between the small engagement tabs at least as large as the distance between the tines of a forklift and the diameter of the engagement tabs is not less than the cross-sectional diameter the tines of a forklift. This ensures that a conventional Forklifts both from the distance of their tines and from their diameter can be inserted into the engagement tabs and thus the transport of the pallet allows.

According to a preferred embodiment of the invention, the engagement tabs are in the Cover perforated and / or cut. The perforation is beneficial if the sleeves are made in stock and delivered to the factories. So can When storing the sleeves, the tabs are not damaged as they are still in the Are integrated. In use, it is no effort to cut through the perforations and expose the tabs.

According to a preferred embodiment of the invention, the sleeve can be printed and coated. The envelope can be left around the pallet in several transport processes be so that advertising prints act on the cover and unfold their advertising function can. An advertising print can also be easily and especially with plastic film apply inexpensively.

The transport and storage device according to the invention consists of a plastic cover 1, which is designed so that it has a wooden pallet 2, which for the Transport of goods is usually used to change clothes.

The Euro pallet DIN 15146 is mostly used. Basically, any type of Pallet can be clad. The dressing up can be achieved by bag-like covering the film over the pallet and / or by welding the film or by welding the film in the shrinking or deep drawing process.

The pallet 2 has a loading area 3 with nine square timbers as feet 4. In These floor planks 13, which connect them, sit in the longitudinal direction. The three floor planks 13 run right and left and along the center of the loading area 3 and connect in each case three feet 4 in the longitudinal direction.

The loading area consists of five planks 18 a, 18 b, 18 c, 18 d, 18 e. The feet 4 are firmly connected to them via crossbars 16, 17, namely a crossbar 17 in the middle of the loading area and front and rear outer crossbars 16. The feet 4 have outer base edges 11 and inner base edges 15. They stand on floor planks 13. For better understanding, the feet of the wooden pallet, which are on the front side of the pallet 8, labeled 4 a, b, c, see FIG. 1.

According to the exemplary embodiment according to FIGS. 4 and 5, the envelope 1 completely surrounds the pallet 2 and close to the contour, wherein the sleeve or the film the contour of the inner base edges 15 and the underside of the crossbar 16, 17 is formed.

All outer contours of the pallet are reshaped or shaped so that they in the longitudinal direction of the pallet, tunnel-like areas between those connecting the feet Create floor planks of the wooden pallet, see Figure 4. Around the foil or Cover to arrange the pallet is suitable for. B. welding the casing 1.

Basically, the shell can be divided into top 6 'and bottom 5'. The The top of the film can have a special protective layer to ward off bacteria and the underside of the film should be designed to be particularly non-slip. All variants and combinations are possible and depend on the desired properties and the location of the clad pallet. The top 6 'of the shell can only be upper Side of the loading area 3, but it can also, if required, to Reach the floor, i.e. imply the lateral height of the pallet.

The film or the cover is preferably welded around the pallet. After that in the four spaces between the planks 18 a, b, c, d, e top and bottom the shell welded together. Since the cross bar 17 the shop surface underside interrupts in the middle of the pallet, there are eight weld seams 19.

It is also possible to apply the film by deep drawing or shrinking. Basically, however, care must be taken to ensure that if the film is damaged, the total tension does not subside in the way that the foil off the pallet hangs.

The material of the cover 1 should be a stretchable, washable, coatable, tearproof and be printable plastic film or a material with properties similar to Plastic materials or foils.

In the embodiment of Figures 1 to 3, the film is like a bag over pulled the pallet. Only the outer contour is recorded. The film stretches from the base edges 11 and horizontally connects the floor planks 13. The top and bottom of the film run parallel, see Figures 1, 2 and 3.

The envelope 1 must be designed so that it encloses the pallet close to the pallet. The The distance between the pallet and the case should not be greater than 2 cm. The size of the Envelope, d. H. the pallet / envelope distance to be selected is the selected plastic film material dependent. A stiffer film tolerates more distance from the pallet without it begins to hang down from the pallet. If the envelope is shrinked or Thermoforming applied, so the process - the casing material has direct Contact with the pallet.

The envelope 1 surrounding the pallet has two opening areas, specifically in the area the front pallet side 8 and in the area of the rear pallet side 9. Die Openings in the film are made through cuts or perforations.

In the opening area of the casing 1 in the area of the rear pallet side 10 there is a large one Engagement tab 7. The cut for creating tab 7 is done with two vertical cuts along the outer edge 11 of the stand and a horizontal one Connection cut at the level of the underside of the floor planks 13. The engagement tab 7 falls like a curtain freely down to the floor planks 13.

It is freely movable at the front and rear and corresponds to the shape of the pallet side 10 rectangular with right angles to the left and right to the outer edges of the base 11 towards, see Figures 2 and 3.

A tab shape with rounded corner areas is also possible. Here is in Area of intersection: outer base edge 11 / floor plank 13 of the angle less than 45 °. If the tab is subsequently, d. H. with the pallet already clad, into which Cut into the film, so an accurate cut is not always possible. Thereby however, there are no functional restrictions.

The opening or engagement area of the casing 1 in the area of the front pallet side 8 consists of two engagement tabs 9 a, 9 b. The engagement tab 9 a runs between the feet 4 a and 4 b and the engagement tab 9 b runs between the feet 4 b and 4 c.

The engagement tab 9 a is cut into the shell 1, with two vertical Cuts along the inner edges of the base 15 and the vertical Horizontal section connecting cuts along the underside of the floor planks 13.

The small engagement tab 9 b is accordingly along with two vertical cuts the inner base edges 15 and a horizontal cut connecting the vertical cuts produced along the underside of the floor planks 13, see FIG. 1.

If the cut is made over the entire stand distance 4 a, 4 b or 4 b, 4 c, this results in rectangular tabs 9 a, 9 b. The tabs 9 a, 9 b can also be chosen in this way be that they do not cover the entire distance between the feet 4 a, 4 b or 4 b, 4 c, so that the tabs 9 a, 9 b are U-shaped. The distance between the small engagement tabs 9 a and 9 b must be chosen at least as large be that the tines of a forklift can be inserted. The diameter too the tabs 9 a, 9 b must not be smaller than the diameter cross section of the tines a forklift.

A tab shape with rounded corner areas of the tabs 9 a, 9 b is also possible. Here is in the area of the intersection: inner edge of the base 15 / floor plank 13 the angle less than 45 °.

The engagement tabs 9 a, 9 b are also curtain-like towards the front and towards the rear movable. They fall freely down to the lower edge of the stand 13. The engagement tabs 7, 9 a, 9 b can be perforated in the shell.

In use:

The pallet welded into the casing according to FIGS. 4 and 5 can be like a plastic pallet be loaded. Should the loaded or unloaded pallet be transported the forklift drives towards the pallet and guides its tines into the tunnel-like Openings that the film forms and releases.

Shape between the feet that are connected lengthways to the floor slabs there are two tunnel arches that are suitable for inserting the forklift tines. Even if due to carelessness the film on the sides or below the loading area is damaged, there is no "sagging" of the film, because the Welding is carried out using eight welds. After welding in the pallet ready for transport and storage. No additional need on the slide Measures are taken.

In the embodiment according to FIGS. 1 to 3 there are different dressing methods the pallet possible, namely the welding of the film around the pallet or that Cover the pallet with a bag-shaped film. If the pallet is welded in, so the entire range is surrounded by the film. The lower part of the The film only touches the floor planks 13, the underside of the film runs parallel to Top of the film or to the loading area. The pallet welded into the shell in this way can be loaded like a plastic pallet.

If the loaded pallet is to be transported, the forklift moves onto the pallet to, its prongs lead into the spaces between the feet 4 a and 4 b and 4 b and 4 c of pallet 2 and cut the film at this point. It goes without saying this measure is also possible on the rear pallet side 10. The pallet 2 can loaded into the plant and stored there. The forklift sets the Pallet and moves away under the pallet, so remain in the area of the tines of the Forklift damage to the film. However, these are immaterial and represent does not constitute a violation of the hygiene regulations. The goods may remain on the pallet and stored in this way.

If an ant is used as a lifting vehicle, it is recommended because of the under the tines arranged rollers to provide the case with entry slots. This can be done quickly with a knife. The slots created in this way also represent does not constitute a violation of the hygiene regulations. The goods may remain on the pallet and stored in this way.

The use of the pallet cladding to be put over like a bag works as follows:

Either the pallet has been delivered with a cover or is dressed on site. To dress the pallet, the large engagement tab 7 is opened or stopped. The, e.g. B. raised by a forklift wooden pallet 2 covered with the plastic cover 1. This can be done on site at the supplier premises.

The casing 1 has then been properly pulled over or put over when the pallet 2 with the front pallet side 8 abuts the rear part of the casing 1 and the engagement tabs 9 a, 9 b between the square timbers 4 a, 4 b and 4 b, 4 c, see Figure 1. The pallet can now be put down. The large engagement tab 7 completely covers the rear pallet side 10.
The pallet 2 is completely on the underside 5 of the shell 1. The shell 1 fits optimally when the engagement tabs are properly seated and the shell covers the pallet without hanging down on it.

In the case of a shell with perforated engagement tabs, the pallet is clad in before first cut the perforation and open the tabs. Then the palette disguised as described above.

It is also possible to use incised or perforated sheath instead of the prepared one Tabs to insert a plastic tube closed on one side and to prepare it on the spot. The plastic tube diameter is on the Pallet. Pallet 2 may only fit in just a little.

The hose is stopped and the pallet 2 is moved in with a forklift, and up to the front end of the pallet 8 at the end of the hose or on the hose bottom arrives. Now the engagement tabs can be in the area of the front pallet side 8 by hand 9 a, 9 b can be cut. In the area of the rear pallet side 10 a protrusion is left at pallet height.

Now the entire projection on the bottom 5 and on the edges 11 is cut away and leave only the top 6 protrusion in full pallet transverse side size. It falls down to the lower edge of the base 13 and covers the rear edge Pallet page 10 complete.

If the pallet 2 is clad in the casing 1, the pallet 2 can be loaded. Should they are moved after the loading process, so the forklift can go to the front Drive up pallet side 8 and guide its tines through the engagement tabs 9 a, 9 b, the engagement tabs fold back and clear the way. The palette can now be lifted normally by the forklift.

The pallet 2 can also be moved from the rear pallet side 10 by forklift or transported. For this purpose, the large engagement tab 7 is opened or opened and the forklift tines into the opening. He lifts the Pallet and moves them to the desired location. Once in operation, the clad pallet with goods to be stored.

If pallets have dimensions other than the usual dimensions, the dimensions are adapt the envelope 1 accordingly.

Conventional plastic films can be used as the cover 1. The slide should be printable. Plastic sheet-like material can also be used but must be tear-resistant and so stable that it does not grind between wood and goods can be or holes arise.
