Definitions

  • the invention relates to a storage and retrieval unit for a rack storage according to the preamble of claim 1.
  • the storage and retrieval machines are used in rack stores to store and remove a wide variety of goods.
  • the storage and retrieval machines have a vertical mast on which a storage and retrieval device can be moved in height.
  • the mast is usually attached to a floor traverse that runs across the mast.
  • Wheels are arranged on the floor traverse in the direction of travel, by means of which the storage and retrieval unit of a travel rail or directly on the floor is supported.
  • the wheels are often made at least partially of plastic materials.
  • the wheels are driven, for example, by means of an electric drive motor.
  • a disadvantage of the known storage and retrieval machines is that the wheels are subject to relatively high wear. To reduce wear, the running speed of the wheels is chosen to be relatively low; at least the running speed of the wheels is limited regularly. In addition, the approach dimension of the known storage and retrieval machines is relatively large.
  • the object of the invention is to propose a storage and retrieval unit that can be moved with little wear and at a relatively high speed.
  • this storage and retrieval machine should have a low travel resistance and enable a low approach dimension.
  • the solution to this problem is given by the features specified in claim 1.
  • the characterizing features of the subclaims contain advantageous refinements.
  • the solution provides that the traversing elements are formed from air cushions which are pressurized with a gas under pressure, the gas emerging from the air cushion forming an air film between the floor and the air cushion on which the floor crossmember can be moved.
  • the air cushions are low-noise and only counter the movement of the storage and retrieval machine with low frictional resistance.
  • the floor load is lower and a higher travel speed is possible.
  • the air cushions are relatively flat, so that a lower approach dimension can be reached easily, which reduces costs. Since the storage and retrieval machine does not need a floor track, it generally has a lower lower approach dimension.
  • the entire device can thus be moved in the Y direction (longitudinal direction of the mast) by a travel path Y and the load can thus be excavated from the rack.
  • the storage and retrieval unit for cornering is not bound to a rail guide.
  • Air cushion-based transfer bridge operation is also easier (easy movement of the transfer bridge into the area outside the rack aisle, since it is rail-independent).
  • the air cushion is formed from a support plate with a compressed air connection, a membrane and a support plate.
  • the compressed air connection is expediently designed as a quick coupling.
  • the floor guide along the travel path comprises a flat, smooth floor surface and right-angled side guide elements which have vertical implement guidance and fall protection.
  • Frictional forces can be reduced if the side guide elements interact with vertical and horizontal rollers or wheels.
  • the floor cross-member can be moved by means of a traversing drive that is stationary at the end of the aisle, with a chain, a toothed belt or a rope as a traction device, or a friction wheel driven on the floor cross-member.
  • the mast at its upper end be supported on a support and guide rail.
  • FIG. 2 shows an embodiment of a side guide arranged on the floor
  • FIG. 1 shows a storage and retrieval unit 1 for a shelf storage (not shown).
  • the storage and retrieval unit has a vertical mast 2 in the form of two spaced-apart parallel vertical supports 2a, the upper free ends of which are connected to one another by means of a connecting support 3.
  • the mast 2 can also be formed from a single vertical support 2a.
  • the two vertical beams 2a are connected by a floor cross member 4 running transversely to the vertical beams 2a.
  • the floor cross-member 4 is supported on the floor 6 by means of air cushions 5 as travel elements.
  • the air cushions 5 are arranged directly below the vertical support 2a.
  • side guide elements 7 On the floor there are two spaced side guide elements 7 in the form of rails, on which side guide wheels 8 are provided for lateral guidance of the floor cross member 7.
  • the side guide elements 7 serve at the same time as fall protection, for which purpose they have a horizontal web 7a at their upper end, on which rollers 8a, which are rotatably mounted, roll on the inside (on the side facing the floor 6) on the floor cross member 4.
  • a lifting truck 11 can be moved along the vertical supports 2a, the drive being effected by means of ropes 12 which can be unwound from a rope drum (not shown) by means of a drive motor 13 or wound thereon.
  • the ropes 12 are deflected on the connecting support 3 by means of freely rotatable rollers 14.
  • the power supply takes place via a switch box 15 shown schematically in the lower right-hand corner of FIG
  • the goods to be put in and out, of which a cuboid good 16 is shown in FIG. 1, are put in and out by means of a schematically illustrated storage and retrieval device 17.
  • the floor traverse 4 can be driven by means of a traction drive arranged stationary at the end of the aisle with a chain, a toothed belt or a rope as a traction device.
  • a traction drive arranged stationary at the end of the aisle with a chain, a toothed belt or a rope as a traction device.
  • a motor-driven friction wheel which is rotatably mounted on the floor cross member 4 (neither of which is shown).
  • the air cushions 5 can have a support plate with a compressed air connection (for quick connection of the compressed air supply), a membrane and a support plate. They are pressurized with a pressurized gas, preferably compressed air, with compressed air emerging from the air cushion 5 on the side facing the base 6, which produces a thin air film between the air cushion 5 and the base 6. This air film ensures that the storage and retrieval unit 1 glides almost smoothly over the floor 6 when it is being moved.
  • a pressurized gas preferably compressed air
  • the floor guide of the storage and retrieval unit 1 is formed by a flat, smooth floor surface 18 of the floor 6.
  • the bottom surface 18 can also be formed by a separate bottom layer (as schematically shown in FIG. 3).
  • Fig. 2 shows a simple embodiment of the side elements 7 for lateral guidance, only the floor cross member 4 with the lateral guide wheels 8 being shown from the storage and retrieval unit 1.
  • the side guide elements 7 are as in this embodiment rectangular profile beams are formed, which are arranged opposite one another.
  • the lateral guide wheels 8 roll on the inside on the vertical side surfaces which are thereby opposite one another.
  • Fig. 3 shows the side guide of FIG. 1 in a side view.
  • the side guide elements 7 have, at their upper end, the webs 7a directed towards the floor cross member 4.

Abstract

L'invention concerne un transstockeur (1) pour entrepôt à rayonnages, comprenant au moins un poteau (2), monté sur une traverse au sol (4), entraînée et soutenue et pouvant être déplacée su sol, par des éléments mobiles. L'invention vise à mettre au point un transstockeur (1) peu sensible à l'usure, déplaçable à vitesse relativement élevée, qui présente une faible résistance au déplacement et une masse de démarrage, située à un niveau plus bas. A cet effet, il est prévu que les éléments de déplacement se composent de coussins d'air (5), sollicités par un gaz sous pression. Le gaz qui sort dans chaque cas du coussin d'air (5) forme une pellicule d'air entre le sol (6) et le coussin d'air (5), sur laquelle la traverse au sol (4) peut être déplacée.
