Definitions

  • the invention relates to a device for holding a load on a load supporting means of a truck according to claim 1.
  • the main purpose of industrial trucks is the picking up, transporting and depositing of loads, these being carried out on a load carrying means, e.g. a load bearing fork, are included.
  • a load carrying means e.g. a load bearing fork
  • the load carrying means is raised only so far that the load can be transported.
  • trucks with stacking function the load carrying means is guided vertically movable on a mast.
  • the invention has for its object to provide a device for holding a load on a load supporting means of a truck, can be fixed with the transport goods significantly different height on the load supporting means.
  • a height-adjustable support device extends approximately horizontally above the load bearing means. If the truck has a mast, then the support device is preferably also guided on the mast, and preferably independent of the load supporting means. However, it is also conceivable to form the holder of the load bearing means so that the carrying device on the holding device the load carrying means can be guided in height adjustable. If a mast is not present, the support device is also guided on the holding device for the load supporting means or on its own scaffolding, along which the support device by means of an adjustment can be performed vertically movable.
  • At least one bag-shaped container of flexible, air-impermeable material is attached or suspended on the carrying device.
  • the container is filled with a granular good.
  • the bag-like container may be formed by a film which consists of plastic, metal, rubber or rubberized fabric and may have a multilayer construction, wherein the outside of the outer layer at least at the bottom of the container for protection against wear and damage has a corresponding coating, while an inner layer ensures air tightness.
  • the bag-shaped container is filled with granular material, e.g. a granulate, wherein the size and shape of the particles are chosen so that the bag can adapt very well to the contour of the load top.
  • particles balls or irregularly shaped particles of different materials may be chosen, e.g. made of metal, plastic, elastomers, rubber, ceramics or wood.
  • a suction device Connected to the interior of the container is a suction device which generates a negative pressure in the container.
  • the negative pressure causes the particles to be pressed against each other and frictional forces prevent the particles from moving easily against each other.
  • the particles are virtually frozen and therefore maintain the previously assumed shape of the container.
  • the container thus fixed transmits the forces necessary for holding the load to the supporting device in a form-fitting manner.
  • the positive connection of the container allows a power transmission in both the vertical and in the horizontal direction. As a result, the load taken by the truck can be safely transported.
  • a self-contained container which can be attached to the support device, but also a bag-like membrane is conceivable, which is sealed to the support device, which has, for example, a support plate.
  • An embodiment of the invention provides that the container circumference a fold or a bead, which is received in a horizontal channel-shaped recess of a frame of the supporting device holding. It is only important that in an adaptation to the contour of the cargo first, the underside of the wall of the container can dodge and the granular material secondly has the ability to dodge in turn laterally or upwards. Therefore, it is expedient to design and hold the top of the container so that it can yield upwards, for example by means of suitable folds or the like.
  • an embodiment of the invention provides that in the container holding means are provided, on which the underside of the bag-like container is suspended.
  • the holding means may e.g. be formed by vertical bands which are connected to a horizontally disposed in the container holding member.
  • the holding element can be held by at least one tube, which is guided into the container in a sealing manner and connected to the suction device.
  • the end of the suction device in the container expediently has a sieve which prevents suction of the granular material.
  • the individual functions of a truck are controlled by a suitable control device.
  • This can also control the functions of the load holding device according to the invention.
  • a separate control device may be provided.
  • This can at least partially control the operation of the load-holding device automatically in accordance with the operation of the load-bearing means.
  • the load-holding device can be lowered onto the item to be transported if the load carrying means executes a stroke after receiving a load or has executed it.
  • a load is first picked up and then brought to a desired height before the vehicle travels to a destination. If the lifting of the load is completed, the activation of the load protection can now take place.
  • the fixation of the load can also be done first, for example, in a stacker with double-decker loading to prevent falling of the load when lifting.
  • the control device may be the lowering of the support device after a terminate further embodiment of the invention, when a pressure on the load measuring sensor generates an output signal that exceeds a predetermined value.
  • the suction device can be switched off automatically by the control device when a pressure sensor in the container detects falling below a predetermined negative pressure.
  • the single figure shows in section schematically a device according to the invention.
  • a holding plate 1 is attached to a guide part 5.
  • the guide member 5 is guided vertically movable independently of a load supporting means in a mast of a truck, not shown, and actuated by a lifting drive, not shown.
  • the lifting drive contains e.g. a hydraulic or pneumatic lifting cylinder, a shaft drive, a threaded spindle or the like.
  • the height adjustment should be indicated by the double arrow 20.
  • a frame 7 is mounted horizontally circumferentially.
  • the frame may have a round or rectangular outline.
  • the size and the outline correspond approximately to the footprint of transport goods on standard pallets. However, other contours and sizes are conceivable.
  • the wall of the frame 7 has on the lower side inside an inwardly projecting bead 24th
  • a bag-like container 2 has an upper wall 26, a lower wall 28 and a peripheral side wall 30.
  • the thickness of the walls can be the same or different. Overall, they consist of a relatively flexible material, which may also have elastomeric properties.
  • the film forming the walls may be single-layered or multi-layered. In any case, it must have an air-impermeable layer. The outside may have a wear-resistant coating.
  • the upper portion of the side walls 30 is received within the frame 7, wherein the bead 24 forms a corresponding indentation 32 in the side wall 30.
  • the upper part of the side walls 30 may be connected to the inside of the frame 7 in a suitable manner, for example by gluing.
  • the upper wall 26 forms with the side wall 30 a circumferential fold 34 such that the upper wall 26 occupies a distance from the holding plate 1.
  • the bottom wall 28 has upwardly directed folds 36 at intervals.
  • a pump 13 is driven by an electric motor, not shown, and is connected via a check valve 12 with a suction line 8 above the holding plate 1.
  • the suction line 8 is connected via connecting pieces 11 with two suction pipes 10 in connection, which are guided sealed over the upper wall 26 into the interior of the container 2.
  • the seal need not be such as to hinder raising or lowering of the top wall 26. This would not be the case anyway if, instead of a rigid tube 10, a yielding conduit would be guided into the interior of the container 2.
  • a horizontal element 9 is mounted on the tubes 10, which is supported on a sieve 6, which is mounted in the lower end of the suction tube 10.
  • bands 3 are attached at intervals, which are connected to the inside of the lower wall 28.
  • a branch 38 is connected to the suction line 8, in which a switching valve 40 is seated.
  • the switching valve 40 connects the suction pipe 8 with atmosphere when it is opened.
  • a granulate 4 is filled in the container 2.
  • the particles of the granules 4 are chosen in size and shape so that the container 2 as well as possible to the contour of a load can adapt, which is arranged on the support means, not shown, below the load holding device shown.
  • the particles may be spheres or irregularly shaped grains made of a wide variety of materials.
  • the operator of the truck On which the load holding device shown is located, has picked up the load with the support means of the truck, he actuates the lowering of the load holding device shown in the figure.
  • the beginning of the lowering movement can be automatically controlled by a controller, not shown, the operation of the load-holding device coupled with the operation of the load supporting means.
  • the support device is lowered, so that the load is securely fixed before it is lifted by the load supporting means.
  • the carrying device When lifting the load, the carrying device must be moved synchronously with the load carrying means. This is easily possible if the framework on which the support device is guided, is attached to the load support means. After a short or longer stroke of the load bearing means, the lowering can be initiated when this stroke is completed.
  • the container 2 is lowered from the top of the load, while the bottom or bottom wall 28 of the container 2 assumes the contour of the load, since the granules 4 is freely movable within the container 2.
  • the end of the lowering movement can also be initiated automatically by a pressure sensor determines when the pressure of the load holding device to the load reaches a predetermined value.
  • the pump 13 After completion of the lowering operation, the pump 13 is put into operation and the switching valve 40 is closed. Thereby, the air is sucked out of the container 2, wherein the check valve 12 prevents an air flow in the reverse direction flows when the pump 13 is turned off.
  • the switching on and off of the pump 13 can be controlled manually or automatically.
  • the pump can be automatically put into operation when the lowering movement of the load holding device is completed. It can be switched off as soon as the air pressure in the container 2 falls below a predetermined value.
  • the suction of the air causes the particles of the granules 4 are pressed against each other and frictional forces prevent easy movement of the particles against each other. This leads to a fixation (virtually freezing) of the instantaneous shape of the container 2.
  • the thus fixed container 2 transmits forces that are necessary for holding the load, form-fitting. This applies both to the transmission of forces between the load and the container 2 and for the transmission of forces between the container 2 and the load-holding plate 1.
  • Load-holding plate 1 and frame 7 are designed so that a positive connection between the container 2 and the load-holding plate 1 and the frame 7, arises, which allows a power transmission in both the vertical and in the horizontal direction.
  • the truck If the truck has arrived at the set point of the load, first his load carrying means is lowered down. Thereafter, the lifting device moves the load holding device described above. This releases the load and can be disconnected. Subsequently, the switching valve 40 is opened. As a result, air can flow from the atmosphere into the container 2. The frictional engagement between the particles of the granules is reduced and the container 2 assumes its original shape.
