Description

The The invention relates to a flat charge carrier (Tablar or the like) for receiving on conveyors transporting goods to be stored on shelves, comprising a frame with a bottom and a circumferential raised Edge and a separate bottom plate, which is inside the frame Edge is arranged.

Of the Use of flat load carriers, such as trays or trays, hereinafter referred to merely as shelves, is in automatic Warehousing and order picking often found. These trays allow it, articles that are very inhomogeneous in their dimensions or the must be transported and stored very gently, despite this inhomogeneity of the articles alike and to handle quickly in modern logistics facilities.

The Tablets available on the market, have the most diverse Forms. So are trays with closed bottom, with floors that have slots or holes (for Excavation of the articles) or with inserted, liftable base plates in combination with slots and / or holes in the floor known.

In In many cases, trays are loaded and unloaded manually. Also known are applications in which trays are loaded automatically and be unloaded automatically.

While the automatic loading is usually done in the river, the automatic discharge must be carried out at special stations with the tray stopped at these stations during unloading becomes, so stands still. The stop will waste precious time and usually at these stations in addition one special equipment (excavation and Abschiebevorrichtung) needed.

So it is from the DE 103 13 576 A1 known to use trays with a peripheral edge and with holes in the bottom, so that the articles can be lifted by lifting pins from below. The articles are then moved by means of a rake (see paragraphs [0013] and [0053]).

From the DE 40 23 290 C1 It is known to lift roof tiles for engobing or glazing of their frame-like pad and then resume, including a cross-down through the support frame lifting member is provided, which lifts the roof tiles from the support frame with steady promotion, ie in the movement, and drops again.

From the DE 298 19 420 U1 a tray or similar support means or transport and / or stacking unit is known, which has for receiving Einstellbehältnissen such as containers or boxes of different sizes on the bottom inside locking means, wherein the locking means is a latchable in the tray, block-like adapter having a high-lying support surface provides and is provided on two opposite sides with engaging in complementary recesses of the tray locking means and on the other two opposite sides with resilient, projecting outwardly locking tabs.

From the DE 297 13 467 U1 is a tray for receiving conveyors to be transported on conveyors and stored in shelves, comprising a bottom plate, reinforced by longitudinal and transverse ribs, a peripheral around the bottom plate raised edge, angle-shaped coupling hooks on the end faces and profiles in the side walls, with each end face two coupling hooks are provided, one of the coupling hooks down and the other coupling hook is angled upward and in the side walls adjacent to the end walls recesses for the gripper of a manipulation device are provided.

It However, there is still the desire for a tray with a Liftable bottom plate used for unloading the tray from a transport in a discharge position is movable, wherein the bottom plate is not can get lost. Furthermore, the tray is a reliable Allow discharge and also cost in large Quantities can be produced.

These The object is achieved by the flat charge carrier reproduced in claim 1 solved.

Thereby, that the frame and the bottom plate so movable with each other are designed that the bottom plate within the frame in vertical Direction relative to the ground above the height of the perimeter Edge between two stops is movable, it is possible the transport and the unloading position of the bottom plate exactly define what a secure workflow with high or complete Automation and high performance allowed.

In In the transport position, the flat bottom plate lies on the ground the frame on the surface, which serves as a stop. In the unloading position, however, the bottom plate is raised maximum and suggests the second stop, the z. B. by a narrowed top opening of the edge is formed. Here, the surface of the bottom plate is at least one Height with the top of the edge, but it may be slightly over.

The narrowed top opening of the edge is preferred formed the longitudinal side edges.

If the bottom plate and the frame additionally detachable connected, can be ensured that the Bottom plate is not separated from the frame during normal operation. Thus, the bottom plate can also be in critical operating conditions do not "leave" the frame and the associated Cause problems, such. B. get stuck in the unloading.

Around To cause the "captivity", the circulating Edge of the frame form a narrowed top opening and the bottom plate in a horizontal parallel position with respect to the bottom a larger dimension than the opening exhibit. Then the bottom plate can look inside the stops Move floor and narrowed opening "normal", but do not leave the frame without violence.

If the bottom plate is additionally designed tiltable, can a targeted removal of the bottom plate, however, by this sufficient Tilting and thus reducing the transverse dimension are made possible.

The Base plate then points in an inclined position with respect to the bottom a dimension corresponding to the opening.

alternative can be provided that the bottom plate in an inclined position with respect to the soil a slightly smaller dimension than having the top opening, the bottom plate deformable designed so that they under or snap out can be used or removed in the frame.

If the bottom plate has profiled longitudinal side edges and the frame has profiled longitudinal insides, on the profiled longitudinal side edges of the bottom plate can be matched to mesh, a good leadership of the Floor plate can be reached during your movement.

additionally can the profiled longitudinal side edges with down, preferably at a 45 degree angle, angled ridges be provided. These webs thus fulfill several functions. First, they cause a guide of the bottom plate. Besides they also allow retention when dimensioned accordingly the bottom plate at the narrowed frame top opening. The webs are thus preferably dimensioned so that the bottom plate in horizontal position with respect to the bottom captive and at an angle is separable from the frame (see above).

by virtue of the oblique angulation stands the surface of the Base plate in the unloading position over the circulating Edge over, so the transported goods are strippable. For this it is therefore advantageous that the frame an angled edge area at the top opening has, which corresponds to the bending of the webs.

In a preferred embodiment, the edge with the Floor connected only via the profile webs. The profiled ones Longitudinal inner sides of the frame are open at the bottom. This allows the webs of the bottom plate to dip into these openings, so that the bottom plate in the transport position not on the webs but just rests.

These Breakthroughs on the two long sides of the frame also support a tilting of the bottom plate in this Case the side edge acting as an elastic stop bar absorbs and so decided to reduce the cross-section contributes and with appropriate design of an elastic deformation in This area allows removal of the plate.

The Outside in this area, however, is smooth and allows about the angled shape over the expression of a phased edge over the frame can be guided vertically and horizontally.

For the penetration of a Bodenplattenhuborgans the frame can central opening in the ground. Alternatively, could also be provided a plurality of openings. The bottom plate can then be tuned to the central opening thickened Have area that stabilizes the bottom plate quasi in this position and reinforced.

additionally Both the bottom plate and the frame can be on the ground Longitudinal and transverse ribs for reinforcement and stiffening exhibit. In the bottom plate, these run in particular diagonally and are provided on the underside thereof. At the bottom of the frame On the other hand, they run in particular orthogonally and are provided on the inside. Thus, in this embodiment, the diagonally extending Rip the bottom plate on the orthogonal ribs of the Soil up.

Around the flat charge carriers as needed, for. For storage, To stack, the frame at the bottom can be a recessed Edge course of the outer edges, so that a charge carrier in a possibly angled outer edge region the opening at the top of the edge of another charge carrier is "pluggable".

Due to the configuration of the charge carrier shown above, it can be cost-effective in Injection molding can be produced. The profiling and openings allow material savings and also the use of an actively cooled form, which can be largely dispensed with movable slide, so that the trays are quickly produced in large quantities.

Further Details, features and advantages of the invention will become apparent the following description of an embodiment based on the drawing, in the

In the figures is a flat carrier or tray 1 for receiving conveyors to be transported on conveyors and stored on shelves.

The tray 1 includes a frame 2 with a floor 3 and with a circumferential raised edge 4 and a separate bottom plate 5 in the frame 2 within the border 4 is arranged.

The frame 2 has a smooth bottom 6 on and one with longitudinal and transverse reinforcing ribs 7 . 8th provided inside 9 on. The longitudinal and transverse reinforcement ribs 7 . 8th are orthogonal to the longitudinal and transverse sides 10 . 11 of the edge 4 ,

The surrounding edge 4 of the frame 2 forms a narrowed top opening 12 for what the otherwise straight border 4 of the frame 2 on the two longitudinal sides an angled edge region 13 at the top opening.

The insides of the long sides 10 of the edge 4 are formed profiled, with the edge 4 with the ground 3 only over the so-formed profile webs 14 connected is. The profile webs 14 are the continuation of the transverse reinforcement ribs 8th of the soil 3 , This is the floor 3 only over these profile webs 14 with the edge 4 on the long sides 10 connected so that the profiled longitudinal insides 10 on the ground 3 are open.

Furthermore, the frame points 2 a central opening 15 for the engagement of a Bodenplattenhuborgans in the ground 3 on.

Furthermore, the frame points 2 on the bottom 6 a circumferential receding edge course 16 the outer edges on, leaving the tray 1 is stackable. This is shown by Rand 4 in addition an angled outer edge area 17 at the top, the angled edge area 13 corresponds to the top opening, leaving the frame 2 a tray 1 in the top opening 12 another tray 1 is pluggable.

The bottom plate 5 and the frame 2 are detachably connected configured, the frame 2 and the bottom plate 5 are designed to be movable with each other, that the bottom plate 5 within the frame 2 in a vertical direction relative to the ground 3 about the height of the peripheral edge 4 is movable between two stops.

The one stop will be through the ground 3 of the frame 2 self-designed and defined at the same time the transport position of the bottom plate 5 (cf 5 , not hatched position of the bottom plate 5 ).

The other stop is through the narrowed top opening 12 trained (see this 5 hatched position of the bottom plate 5 ).

Thus, a "captivity" is caused by the fact that the peripheral edge 4 of the frame 2 the narrowed top opening 12 trains and the bottom plate 5 in horizontal parallel position with respect to the soil 3 has a larger dimension than the opening.

The bottom plate 5 So it can be within the stops of ground 3 and narrowed opening 12 Move "normal" or raised and lowered, but not the frame 2 Leave "without violence".

The bottom plate 5 but is also within the frame 2 tiltable designed so that a targeted removal of the bottom plate 5 by sufficient tilting or tilting and thus shrinking the transverse dimension is possible (see 6 , not hatched position of the bottom plate 5 ).

The bottom plate thus has an oblique position with respect to the bottom 3 one of the opening 12 corresponding dimension.

The bottom plate 5 also has profiled longitudinal side edges 19 on, the profiled insides of the long sides 10 of the edge 4 or the profile webs 14 are adjusted. The profiled longitudinal side edges 19 are with down-angled ridges 18 Mistake.

These bridges 18 fulfill several functions. First, they cause a guide of the bottom plate 3 at the profile webs 14 of the edge 4 ,

In addition, they allow with a corresponding dimensioning and the retention of the bottom plate 5 at the narrowed frame top opening 12 ,

The webs are thus preferably dimensioned so that the bottom plate 5 in a horizontal position with respect to the soil 3 captive and at an angle from the frame 2 is separable (see above).

Due to the matching oblique angulation 13 and the angled webs 18 stands the surface of the bottom plate 5 in the unloading position over the peripheral edge 4 over, so that the transported goods are strippable.

Because the edge 4 with the ground 3 only over the profile webs 14 connected are the profiled longitudinal insides 10 of the frame 2 on the ground 3 open. This allows the webs 17 the bottom plate 5 immerse in these openings, leaving the bottom plate 5 not in the transport position on the webs 18 rests.

The bottom plate 5 points to its underside 20 also longitudinal and transverse ribs 21 . 22 for reinforcement, which run diagonally. With these longitudinal and transverse ribs 20 . 21 it lies on the longitudinal and transverse ribs 7 . 8th of the soil 3 on. The bottom plate 5 also has one on the central opening 15 tuned thickened area 23 on.
