Definitions

  • the invention relates to a charge carrier according to claim 1.
  • Load carriers are often standardized transport aids used in logistics to hold one or more piece goods, containers, etc., to allow simple automatic handling in the area of conveyor and storage technology. If these load carriers are essentially flat, one also speaks of trays.
  • DE 102008026326 B4 discloses a flat load carrier, in particular a shelf or the like, for receiving goods to be transported on conveyor systems and stored on shelves, comprising a frame with a base and a circumferential raised edge and comprising a separate base plate, which Frame is arranged within the edge, wherein the frame and the base plate are designed to be movable with one another such that the base plate is movable within the frame in the vertical direction relative to the ground over the height of the peripheral edge between two stops.
  • the movable base plate is guided by profile webs which protrude from the edge and engage in corresponding grooves in the base plate.
  • the object of the present invention is to provide a load carrier that can be stacked on top of one another with less height consumption.
  • the edge of the frame is designed in such a way that it contacts the separate base plate, in particular its projections, of the load carrier above it from below when stacked, this can be lifted and the stack height is thus reduced.
  • the load carrier or its edge of the frame is preferably free of projections on the inside, i. H. has no inwardly protruding projections, so that it becomes possible to stack the load carriers on top of one another with a lower height, since the profile webs according to the prior art are now out of the way and no longer impede the nested interlocking of the load carriers.
  • the load carrier with low side walls or the edge of the frame is suitable as a tray or with higher side walls as a container, preferably for use in warehouses, distribution centers, etc.
  • the edge of the frame has inwardly open recesses and the separate base plate has projections, in particular designed as bevelled lips directed outwards, which project into the recesses (in the edge).
  • the projections serving as guide lugs of the base plate thus allow the base plate to be guided in the inwardly open recesses.
  • the top opening is preferably not narrowed, or even widened.
  • edge of the frame is designed in such a way that, in the stacked state, it does not contact the projections of the separate base plate of the load carrier underneath from above.
  • the projections of the load carrier in the stack which serve as guide lugs on the base plate, can touch the frame (or the top of the edge) of the lower load carrier below, so that the base plate of the upper Load carrier is raised from the lower frame, so as to allow maximum immersion of the upper frame of the upper load carrier in the lower load carrier.
  • the base plate is only raised so far that its upper side does not touch the underside of the frame of the next load carrier to be stacked. So there remains a smaller distance.
  • the rim of the frame at the top opening has second recesses which open upwardly and inwardly to receive outwardly directed reinforcing ribs of the frame when stacked.
  • the load carrier can thus be stiffened by means of the reinforcement ribs without these having a negative effect on the stacking.
  • edge has lateral indentations in the outer side surfaces in the front and rear area.
  • intervention surfaces e.g. B. for linear retractable and extendable handling extensions (fingers) of telescopic arms of load handling equipment, especially shuttles, to push the load carrier or pull it up, or z. B. of tines of stacking devices, by means of which the load carriers are stacked fully automatically.
  • the guide grooves can be designed with widened ends (inlet and outlet).
  • corresponding centering recesses or centering projections can be arranged on the upper side of the rim and on the underside of the rim, so that they engage in one another during stacking.
  • the emission of noise on conveyors can be greatly reduced, since the lowest point can be reduced to two (or more) lowest points on the ground is divided and thus the collision on conveyor rollers is dampened.
  • the surface set back from the ground plane can also be circular, diamond-shaped or polygonal in the end regions.
  • the deflection of the load carrier is counteracted, otherwise the edges in the tray base would hit the conveyor rollers more and the noise emissions would increase.
  • the load carrier can thus have a defined (possibly uninterrupted) outer contact edge for guidance and as a stop provide external means in use.
  • FIG. 1 shows a schematic perspective view of a load carrier designed as a tray, obliquely from above;
  • FIG. 2 shows a schematic perspective view of the tray from FIG obliquely below
  • FIG. 3 shows a plan view from above of the base of the shelf from FIG. 1 without the base plate inserted;
  • FIG. 4 shows a comparison of the tray from FIG. 1 with the bottom plate lowered versus the bottom plate completely raised, as sectional views;
  • Figure 5 shows a comparison of a stack of the tray of Figure 1 versus a stack of a prior art tray as sectional views.
  • FIGS. 1 to 4 show a flat load carrier, designated as a whole by 1, which is also designated as a shelf.
  • the substantially rectangular shelf 1 comprises a frame 2 with a base 3 and with a peripheral raised edge 4 and a separate base plate 5 which is arranged within the frame 2 and is vertically movable therein.
  • the base plate 5 is designed to be movable in the frame 2 in such a way that the base plate 5 can be moved within the frame 2 in the vertical direction relative to the base 3 over the height of the peripheral edge 4 between two stops.
  • the edge 4 of the frame 2 is free of projections on the inside or has no inwardly protruding projections.
  • the edge 4 of the frame 2 has inwardly open recesses 6, and the separate base plate has projections 7, which are designed as outwardly directed lips that are bevelled at the top and protrude into the recesses 6.
  • the recesses 6 are closed at the top and form the upper stop for the base plate 5 or the lips 7 at the top.
  • the bottom stop is formed by the bottom 3 (of the edge).
  • the recesses 6 are open towards the bottom 3, so that the lips 7 extending into them can be contacted from below.
  • the top opening 8 itself is not narrowed.
  • the bottom 3 has a central rectangular opening 9 for the passage of a bottom plate lifting member.
  • the base plate 5 has a downwardly directed block 22 which protrudes into the central rectangular opening 9 when the base plate 5 is in the fully lowered position.
  • the block 22 is formed with ribs 23 arranged crosswise.
  • the floor 3 is also formed with reinforcing and stiffening ribs 26 arranged crosswise.
  • the frame 2 on the underside 10 has a circumferential recessed edge profile 11 of the outer edges, so that the tray 1 can be stacked, for which purpose the recessed edge profile 11 is inserted into the top opening 8 .
  • the edge 4 of the frame 2 is designed in such a way that, in the stacked state, it does not contact the projections 7 of the separate base plate 5 of the tray 1B underneath (cf. FIG. 5).
  • the rim 4 of the frame 2 has, at the top opening 8, second recesses 14 which are upwardly and inwardly open to accommodate outwardly directed reinforcing ribs 15 of the frame 2 when stacked. At the same time, the reinforcing ribs 15 protect the lips 7 in the non-stacked state.
  • the edge 4 has in the outer side surfaces 16 in the front and rear area lateral depressions 17 as pockets for handling means.
  • the base 3 has guide grooves 18 running transversely to the longitudinal side, which can be used to interact with guide webs on a shelf (see above) and have widened inlets and outlets 24 for easier threading.
  • Corresponding centering recesses 19 or centering extensions 20 are arranged on the upper side of the edge 4 and on the lower side of the edge 4 in order to achieve better centering when the trays 1 are stacked.
  • the bottom 3 has an oval, centered and slightly recessed surface or depression 21 on the underside, which reduces noise emissions on conveyors.
  • the tray 1 is designed in such a way that the uppermost, outermost edge 25 of the rim 4 defines the widest point of the tray 1 and the outer side surfaces 16 fall back by approximately 1 degree from the vertical.
  • FIG. 5 shows a comparison of a stack of the tray from FIG. 1 with a stack of a tray from the prior art. It can be seen that the stack of the tray 1 according to the invention (compare FIG. 5B) is stacked smaller in height than the tray from the prior art (compare FIG. 5A). It can be seen that the stacking height X1 according to the prior art is greater than the stacking height X2 according to the invention, although the height L1 of the edge 2 according to the prior art is equal to the height L2 of the edge 2 according to the invention.
  • the stacking height can be reduced according to the invention, since the edge 4 of the frame 2 in the stacked state does not contact the lips 7 of the separate base plate 5 of the underlying tray 1 from above, while the recesses 6 open downwards towards the base 3 are, so that extending lips 7 can be contacted from below by the edge 4 in order to be lifted.
