Definitions

  • the invention relates to a shelf conveyor for high-bay storage with a mast, a load receiver movable thereon by means of a lifting device and a device for transferring or taking over the load to or from the shelf.
  • High-bay warehouses are used to achieve high storage densities. These are operated by shelf-type conveyors. In order to increase the storage density, it is advisable to arrange two or more consecutive storage places next to each other and parallel to the rack aisle, so as to reduce the number of rack aisles and thus minimize the space that cannot be used for storage.
  • the storage bins located one behind the other can then be operated using satellite vehicles.
  • satellite vehicles also called shuttles, run from Lastauf of the rack conveyor onto the storage bins of the high rack, can pick up or drop loads there and return to the load pickup.
  • the load suspension and the shelf have rails on which the satellite vehicle moves with corresponding rollers.
  • the invention has for its object to provide a shelf conveyor in which an undisturbed transfer or takeover is possible.
  • the load pick-up can be mechanically locked essentially continuously on the mast within its lifting range.
  • a lock can be provided between the mast and the load suspension be.
  • the locking device has at least one chain and at least one chain wheel which interacts with it, one part of which is attached to the mast, the other to the load suspension, and that at least one chain wheel can be locked in any rotational position.
  • the locking device has at least one toothed rack or toothed belt and at least one toothed wheel or toothed belt wheel cooperating with it, one part of which is attached to the mast, the other to the load receiver, and that at least one toothed wheel or Toothed belt wheel can be locked in any rotational position.
  • a stepless locking is possible by blocking the chain or gear wheel or toothed belt wheel in any rotational position.
  • the mast extends over the entire height of the lifting range, it is advantageous that the chain or the toothed rack or the toothed belt on the mast and the chain wheel or the toothed wheel or the toothed belt wheel are arranged on the load receiver, and in this way results in a simple construction with linear engagement.
  • the infinitely variable locking of the chain or gear wheel or toothed belt wheel can be realized in a structurally simple manner by assigning a brake disc to the chain wheel or gear wheel or toothed belt wheel, on which a shoe or disc brake acts.
  • a brake disc to the chain wheel or gear wheel or toothed belt wheel, on which a shoe or disc brake acts.
  • any other type of brakes can also be used for this.
  • the control of the lifting device of the load suspension so that the load transfer / transfer after reaching the desired position, the control and the locking of the locking of the load suspension on the mast, z. B. the brake can be switched on.
  • the respective position can be scanned directly on the shelf, for example optoelectrically. This results in the possibility, either manually, but preferably automatically, of loading and unloading the load suspension in a short amount of time.
  • the lifting device In the case of large rack heights, the lifting device consists of a cable pull in a known manner. When the desired height of the load suspension is reached, the control of the cable pull is switched off and the locking of the load suspension is switched on. This makes it possible to load and relieve the load by changing the height of the hoisting rope.
  • FIGS. 1 and 2 show a section of a high-bay warehouse, each with a shelf 1, 2 on both sides of a shelf aisle 3.
  • Each shelf has a plurality of shelf spaces arranged one above the other and, parallel to the shelf aisle 3, next to one another.
  • two or more shelf spaces can also be arranged one behind the other on each shelf level.
  • a rack conveyor 4 can be moved in the rack aisle 3, which in the exemplary embodiment shown has a chassis 5 and a mast 6 and runs on or in guides 7, 8 on the floor and on the ceiling.
  • a remote-controlled travel drive 9 is also located on the chassis 5.
  • a load bearing 10 is guided by means of a lifting device 11 so that it can be raised and lowered.
  • the lifting device device 11 is formed in the embodiment shown by a cable 12, which is guided via a driven pulley 13 at the head of the mast 6 and via a pulley 14 connected to the load bearing 10.
  • a device 15 for transferring or taking over the generally palletized goods 16 is arranged on the load suspension 10.
  • this device 15 is designed as a satellite vehicle.
  • the load receiver 10 and the shelves have corresponding rails on which the satellite vehicle 15 can be moved.
  • the satellite vehicle 15 has a travel drive, not shown, which is supplied from the rack conveyor 4, for example, by cable.
  • the mast 6 is shown in an enlarged and interrupted view.
  • the upper cable pulley 13 and - in FIG. 4 - a part of the load suspension 10 can be seen.
  • a lock 17 is provided between the mast 6 and the load receiver 10, which in the exemplary embodiment shown consists of two chains 18 tensioned in parallel, optionally of several chain sections, and at least one chain wheel 19 running therein.
  • the chains are attached to the mast 6 in a prestressed manner, while the chain wheel is mounted on the load suspension 10.
  • the load receiver 10 as shown in FIG. 4, has a bearing block 20 on which the chain wheel 19 is mounted via an axis 21.
  • the sprocket 19 is indicated in several positions for the transfer or transfer of loads.
  • a brake 22 is provided for this purpose, which in the exemplary embodiment shown is formed from a brake disk 23 and a shoe or disk brake 24.
  • the brake disc 23 is seated on the axis 21 of the chain wheel 19, which in the exemplary embodiment shown is designed as a twin wheel, while the shoe or disc brake 24 is arranged on the bearing block 20.
  • the lifting device or the cable pull 12 is stopped and the load pickup 10 in the position reached by actuating the brake 22 in the lock formed from the chain wheel 19 and chain 18 blocked.
  • the loaded or unloaded satellite vehicle 15 can move to the selected racking position without any problems and can also be moved back to the load suspension without jolts.
