Definitions

• the invention relates to a pallet for transporting and storing goods.
• a truck with a movable loading floor is known.
• the loading floor is formed by an endless loading belt, which is guided at the ends of the loading area via deflection rollers.
• the loading belt has several partial longitudinal belts and each cross-member of the chassis with its cross-sectional profile projects into the space between two adjacent partial longitudinal belts.
• a horizontal conveyor is known from DE-U-94 02 204, in which a number of pallets are conveyed on roller chains on an endless path.
• the pallets are held by pawls at standby stations, loading stations and unloading stations. If the pawls are released, the pallets are taken from the roller chains by friction.
• the pallets On the underside, the pallets have counterholders which engage on the underside of the roller chains and are dimensioned such that their end faces bear against rollers of the chains in the region of the deflection wheels of the roller chains, so that the movement of the roller chains is transmitted to the pallets in a form-fitting manner .
• a pallet for transporting and for unloading loads is known.
• the bottom of the pallet is formed by a variety of rollers that overlap extend almost the entire width of the pallet and are held in a rectangular frame.
• the pallet rests on side rails so that a forklift can drive under the pallet and lift it.
• the pallet is lifted by the fork lift truck, the fork arms of which are equipped with a corresponding number of rollers.
• the rollers of the pallet and the forklift each have the same diameter and are arranged in the same grid, so that the rollers of the pallet come to rest between two rollers of the forklift.
• the forklift places the pallet at an unloading position and moves back.
• the rollers of the forklift roll on the ground and transfer their rotational movement to the rollers of the pallet, so that the load lying on the pallet rolls off the pallet.
• This rolling movement is exactly the opposite of the backward movement of the forklift and the pallet, so that the load remains in position as it rolls off the pallet.
• Lifting cranes are often required to transfer large machines to and from a truck.
• lifting cranes can sometimes not be used because, for example, the gate or ceiling height of the factory buildings is too low. If other means are used to unload the machine, there is often a risk of damage to the machine.
• Another problem is that it takes a lot of time to load picked goods.
• the invention has for its object to provide a range that can be used in many ways and can be unloaded in a particularly simple manner.
• the pallet has a roll-off base. Because the floor can be rolled off, heavier machines or picked goods can be unloaded in such a way that the pallet is pulled away from under the machine or the picked goods.
• the loaded pallet is moved to the installation site using a forklift.
• the forklift can use the fork to engage in special shafts provided at the rear end of the pallet on the underside. At the place of installation, the forklift then slightly raises the rear end of the pallet and moves back so that the machine, the picked goods or the other load slowly slides off the pallet on the rollable floor.
• the pallet can be formed by two longitudinal beams, which are connected by several cross struts, with the rollable floor running on a closed, endless path parallel to the longitudinal beams around guide rollers, which are parallel to the cross struts at the front and rear end of the pallet .
• the upper load-bearing strand of the rolling, circumferential floor can rest on a carrier plate, so that the machine or the other good rests on a flat surface.
• the pallet can be mobile on heavy duty castors.
• Rigid heavy duty castors are suitably provided at the front end of the pallet and steerable heavy duty casters at the rear end.
• the pallet can also have only the rigid heavy-duty rollers at the front end.
• a turntable is then arranged on the underside, which has a receiving shaft into which the fork arms of a forklift can engage in order to raise the rear end and to move the pallet.
• Pallets for lighter loads do not have to have rollers, as they can be lifted by a forklift truck.
• the roll-off floor can be driven by a hydraulic motor or an electric motor, which is supplied by the hydraulics or the battery of the forklift.
• the pallet can also have a drive roller for the rollable floor, which can be brought into drive contact with the ground or other underground.
• a drive roller is preferably arranged at one end of the pallet, which can be brought into drive contact with the ground by lifting the other end of the pallet.
• the drive rollers can also be driven by a gear or a drive chain from the rigid heavy duty rollers at the front end of the pallet.
• a switchable coupling is expediently provided between the drive rollers and the heavy-duty rollers.
• a machine or other load can also be reloaded into a truck via a loading ramp.
• the roll-off floor consists of a chain belt.
• the roll-off floor is designed as a plastic band.
• a so-called black box can be attached to the pallet, which continuously records the environmental conditions to which the pallet is exposed during transport. It is particularly useful to continuously record the vibrations and the temperature conditions. In the event of damage to the goods or spoiled goods, the cause of the damage or spoilage of the goods can then be determined subsequently.
• the pallet according to the invention also enables the pre-commissioning of small parts and smaller packaging units regardless of the actual loading time. The small parts and smaller packaging units are put together on a single pallet in the warehouse, whereby the dimensions of the pallet are only limited by the size of the truck loading area. After the truck arrives, the pallet with the goods that have already been picked is pushed into the truck via the loading ramp.
• the pallet can remain in the truck to bring the goods to their destination on the pallet in the hall or to another place where the goods are to be unloaded.
• the pallet is then raised again by means of a forklift at the rear end, so that the drive roller comes into contact with the ground, or the coupling between the heavy-duty rollers and the drive rollers is engaged and the pallet is then withdrawn, so that the goods standing on the rollable floor are removed the pallet is unloaded.
• the goods can be placed in the truck by lifting the rear end of the pallet and pulling the pallet back if the pallet itself is not to be transported.
• the pallet according to the invention also makes it possible to carry out commissioned storage, since the goods can be put together on the pallet at any time in the warehouse.
• the pallet in question can be pushed into the truck immediately.
• the goods can be loaded from the pallet into the truck immediately or the goods can be transported on the pallet in the truck and then from the pallet at the destination. unloaded.
• the pallet can also be shipped using the pool method, so that the advantage of easier unloading at the destination is exploited.
• the pallet can be locked and is also suitable as a customs goods box and for more secure and faster shipping of customs goods.

• the pallet 10 has two side longitudinal members 12 which are connected by a plurality of cross struts 14, so that a rectangular frame is formed.
• deflection rollers 16, 17 are mounted in front of the foremost and behind the last cross strut 14 and parallel to these cross struts 14.
• An endless chain belt 18, which spans the entire width between the longitudinal beams 12, is guided over the deflection rollers 16, 17 as a rollable base.
• a support plate 20 is fastened on the cross struts 14, on which the upper run of the chain belt 18 rests. The lower run is guided by means of guide rollers 22.
• a drive chain 24 is attached to each of the two lateral edges of the chain belt 18.
• the pallet 10 rolls on heavy duty rollers 26, which are provided on the underside of the side members.
• a drive roller 28 is mounted, which is coupled to a gear wheel which engages in the drive chain 24.
• the gear wheel can also be attached directly to the drive roller 28 as a toothed ring.
• the drive roller 28 has no ground contact because it sits slightly higher than the heavy duty rollers 26. Only when the rear end of the pallet 10 is raised a little does the drive roller 28 have ground contact and rotate when the pallet is moved. This movement v ⁇ ird is transferred to the chain belt 18, in the opposite direction, since the gearwheel engages on the outside of the drive chain 24. The chain belt 18 is then apparently stationary.
• a one-way clutch can be present, so that the chain belt 18 only at a reset of the pallet 10 is driven, in the forward direction.
• a clutch can also be provided, with which the gear wheel can be engaged and disengaged with the drive roller 28.
• the two rearmost cross struts 14 'and 14' ' are provided with shafts 30 which are horizontal, longitudinal openings in the cross struts 14', 14 '' and into which the stacker fork can be inserted is.
• the last cross strut 14 ' is rigidly connected to the frame and its shaft 30' corresponds to approximately 150% of the fork width and is rounded at the edges 32.
• the penultimate cross strut 14 ′′ is connected to the frame via a swivel joint 34 and can thereby be displaced horizontally in the transverse direction.
• the shaft 30 '' of this cross strut 14 '' corresponds precisely to the stacker fork (including the guide nose of the stacker fork). In the vertical direction, the shafts 30 are dimensioned such that the fork with the metal hook, which will be explained later, passes through them.
• heavy-duty rollers 26 ' are arranged on each side of the pallet, which can thereby be steered by means of the swivel joint 34. The steerable heavy-duty rollers 26 'can thus be controlled by pivoting the forklift fork, so that the pallet 10 can be moved and controlled with the aid of a forklift.
• an access ramp 36 is articulated, which can be folded down by means of a lever (not shown) for loading and raised for transport.
• the front edge of the carrier plate 20 is set back somewhat and from there the chain track 18 runs downwards over a guide roller 38 at a flat angle to the front deflection roller 16, which is consequently somewhat lower than the rear deflection roller 17.
• the nei supply chain chain 18 continued in a short ramp 40 to just above the floor.
• Small, vertical metal rollers (not shown) are provided at the corners of the frame for better rolling on the side walls in the truck.
• a container can be built on the frame consisting of the longitudinal beams 12 and the cross struts 14.
• side walls 42 are fastened by means of guide bolts in plug-in holes 44 in the side members 12.
• the side walls 42 are stabilized by cross bars or rods (not shown) on the front and back.
• the side walls 42 consist of aluminum or sheet metal which offers little resistance (ease of sliding). They can be supplemented on the front and rear sides by lockable swing doors.
• the pallet 10 according to the invention serves to simplify loading and to save time in the transport system and for goods picking.
• the pallet 10 can be loaded in the usual way by means of forklifts, lift trucks or hand trucks.
• the laterally attachable walls 42 made of aluminum or sheet metal serve to be able to stack the goods up to the height of the truck, particularly in the case of small packaging or freight forwarding goods. It is irrelevant here if the pallet 10 is only partially loaded due to smaller quantities.
• the loading process is as follows: The forklift approaches the pallet 10 with a metal hook that is attached to the fork and stands up.
• the ramp 36 is folded up with the lever.
• the forklift moves the forks into the provided shafts 30 as far as it will go. Due to the steering axis of the heavy duty casters 26 'and the movable cross strut 14'', the pallet 10 can be maneuvered by means of the forklift and pushed into the truck.
• the vertical metal rollers at the corners of the pallet 10 provide easier resistance when moving in give. If the pallet does not travel to the destination in the truck, the forklift slightly raises the pallet 10 and pulls it backwards out of the truck.
• the forklift does not lift the pallet 10, but only drives backwards so that the fork is pulled out of the shafts 30 and the pallet 10 remains in the loading space of the truck.
• the pallet 10 is pulled out of the truck with a forklift, the forklift at the front end of the fork having the upward metal hook and driving the fork into the shafts 30 so that the metal hook engages in front of the rearmost cross strut 14 '.
• disengaging a coupling between the drive rollers 28 and the chain belt 18 prevents the goods from sliding off the pallet 10 when the pallet 10 is pulled back.
• the pallet 10 is thus moved into the warehouse and can then be unloaded by lifting and pulling the pallet 10 backwards, the clutch being engaged beforehand.
• Crane loading is also possible, for which the entire range is also moved by crane using eyelets on the side members.
• Figures 4 to 8 show a second embodiment of the pallet according to the invention.
• the second embodiment corresponds essentially to the first embodiment.
• a steering bolster 50 is provided at the rear end of the pallet 10, which consists of a turntable 52 and a shaft 54.
• the shaft 54 is dimensioned so that a forklift can move the fork arms into it and then lift the rear end of the pallet 10 and push the pallet 10 forward or backward.
• the pallet 10 can be steered by the articulated connection which is produced by the steering bolster 50.
• the drive roller 28 is driven by the heavy-duty rollers 26 by means of gear wheels 56, 58.
• the drive chain 24 transmits the rotation from the drive roller 28 to the deflection roller 16.
• the drive connection between the drive roller 28 and the heavy-duty rollers 26 can be coupled by means of a toothed coupling, so that the drive connection can be released.
• the gear wheel 56 seated on the axis of the heavy-duty rollers 26 is shifted via a Bowden cable 60 by means of a lever 62.
• a clutch not shown in detail, is integrated in the clutch, so that also in coupled state, the pallet 10 can be pushed forward without the rotation of the heavy duty rollers 26 being transmitted to the chain or plastic belt 18.
• the chain belt 18 is divided into three belts of the same width.
• the standing metal rollers 64 at the corners of the pallet can be seen in Fig. 5.
• the rolling ramp 40 at the front end of the pallet 10 is designed as a spring-loaded flap.
• the rolling ramp 40 is pivoted upward in the idle state by a spring, not shown in detail.
• the unwind ramp 40 is folded down, as a result of which the step at the front end of the pallet 10 is bridged and the load can be unrolled smoothly.
• the electric or hydraulic motor 70 can also be supplied by another energy source or have its own energy supply, for example accumulators, for driving the chain or plastic belt 18.
