Description

The invention relates to a flat load carrier (tray or the like) for receiving conveyors to be transported on conveyors and stored on shelves, comprising a frame with a bottom and a peripheral raised edge and a separate bottom plate, which is arranged in the frame within the edge the frame and the bottom plate are configured to be movable with each other so that the bottom plate within the frame in the vertical direction relative to the ground over the height of the peripheral edge between two stops is movable.

The use of flat load carriers, such as trays or trays, hereinafter referred to merely as trays, is often encountered in automatic storage and order picking. These shelves make it possible to handle articles that are very inhomogeneous in their dimensions or that must be transported and stored very gently, despite this inhomogeneity of the articles similar and fast in modern logistics facilities.

The trays available on the market have many different characteristics. So are trays with a closed bottom, with floors that have slots or holes (for excavating the article) or with inserted, liftable floor panels in combination with slots and / or holes in the ground known.

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

While the automatic loading is usually done in the river, the automatic unloading must be carried out at special stations, whereby the tray is stopped at these stations during the unloading, thus stands still. Due to the stop, valuable time is lost and as a rule a special equipment (excavation and removal device) is required at these stations.

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 shelves to be stored, comprising a bottom plate reinforced by longitudinal and transverse ribs, a peripheral around the bottom plate raised edge, angular coupling hooks on the end faces and profiles in the side walls, wherein on 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.

The DE 10 2004 056 865 A1 discloses a box-like container, in particular small load carrier for receiving pourable and settable small property with a bottom and this frame-like side walls, wherein the floor in the height direction guided displaceably on the side walls and so gradually by means of an attacking from the outside lever up and down, that the emptying and / or filling of the container with small material in a lying in the region of the high edge of the side walls manipulation level is vornehmbar.

From the not pre-published DE 10 2008 011 537 A1 is known a plastic tray that includes a bottom and four side walls. The four side walls are made in one piece and form a frame of an angle profile, in which the plate-shaped bottom is inserted as another one-piece component. At the upper edge of the frame inwardly directed projections are arranged, which limit the raised and lowered ground in his path.

However, there is still a desire for a tray with a liftable bottom plate, which is movable for unloading the tray from a transport to an unloading position, in which the Floor plate can not be lost. Furthermore, the tray should allow a reliable discharge and also be inexpensive to produce in large quantities.

This object is achieved by the reproduced in claim 1 flat charge carrier.

Characterized in that the bottom plate has profiled longitudinal side edges and the frame has profiled longitudinal inner sides which are adapted to the profiled longitudinal side edges of the bottom plate for engagement, a good guidance of the bottom plate can be achieved in their movement.

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

The narrowed top opening of the rim is preferably formed by the longitudinal side edges.

Since the bottom plate and the frame are additionally designed releasably connected, it can be ensured that the bottom plate is not separated from the frame during normal operation. Thus, the bottom plate can not "leave" the frame even in critical operating conditions and cause the associated problems, such. B. get stuck in the unloading.

To effect the "captive", the peripheral edge of the frame forms a narrowed top opening and the bottom plate has a greater dimension than the opening in a horizontal parallel position with respect to the bottom. Then the bottom plate can move "normally" within the bottom and narrowed opening stops, but can not leave the frame without the force of impact.

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

The bottom plate then has an oblique position with respect. The bottom of the opening corresponding dimension.

Alternatively, it can be provided that the bottom plate in oblique position with respect. The bottom has a slightly smaller dimension than the top side opening, wherein the bottom plate is designed deformable, so that they can be inserted or snapped in or out of the frame is.

In addition, the profiled longitudinal side edges may be provided with downwardly, preferably at an angle of 45 degrees, angled webs. These webs thus fulfill several functions. First, they cause a guide of the bottom plate. In addition, they allow with a corresponding dimensioning also the retention of the bottom plate to the narrowed frame top opening. The webs are thus preferably dimensioned so that the bottom plate in the horizontal position with respect. The bottom is captive and separable from the frame at an angle (see above).

Due to the oblique bending the surface of the bottom plate is in the unloading position on the peripheral edge, so that the transported goods are strippable. For this purpose, it is therefore advantageous that the frame has an angled edge region on the upper side opening, which corresponds to the bending of the webs.

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

These breakthroughs on the two longitudinal sides of the frame also support a tilting of the bottom plate, which in this case absorbs acting as an elastic stop strip side edge and so decisively contributes to reduce the cross section and allows for appropriate interpretation of elastic deformation in this area removal of the plate.

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

For the passage of a Bodenplattenhuborgans the frame may have a central opening in the bath. Alternatively, a plurality of openings could be provided. The bottom plate may then have a thickened region tuned to the central opening, which stabilizes and reinforces the bottom plate, as it were, in this position.

In addition, both the bottom plate and the frame may have longitudinal and transverse ribs on the bottom for reinforcement and stiffening. In the Base plate run this particular diagonal and are provided on the underside. At the bottom of the frame, however, they are in particular orthogonal and are provided on the inside. Thus, in this embodiment, the diagonally extending ribs of the bottom plate rest on the orthogonal ribs of the bottom.

To the flat charge carriers as needed, for. As for storage, to stack, the frame at the bottom may have a recessed edge profile of the outer edges, so that a charge carrier in a possibly angled outer edge region of the opening at the top of the edge of another charge carrier is "plugged".

Due to the embodiment of the charge carrier shown above, it can be inexpensively manufactured by injection molding. The profilings and openings allow a saving of material and also the use of an actively cooled mold, which can be largely dispensed with movable slide, so that the trays are produced quickly in large quantities, Further details, features and advantages of the invention will become apparent from the following description of an embodiment with reference to the drawing, in which

8th a section along the line DD through the bottom plate 3 shows.

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.
