Disclosure of the invention

The invention relates to an unloading system for unloading at least one container transported on a bed of a rolling pallet from the rolling pallet to an unloading place, which at least includes: a) at least one rolling pallet with at least three rollers rotatably mounted opposite the loading area for the at least one container; wherein at least one front roller is arranged in the area of a front edge seen during unloading in the rolling direction of the rolling pallet, and

b) at least one container, which is positionable on the loading area of the rolling pallet.

The term "container" is to be seen in this context very far and includes next to self-contained containers also upwards and / or at least one side open containers as well as wire or mesh baskets, which have at least on the side surface a wire or grid mesh.

The rolling pallet preferably has four opposite the loading surface for the at least one container rotatably mounted rollers, two front rollers and two rear rollers, which are each aligned with each other. Above and below, the terms "front" and "rear" always refer to the position of the elements marked with these terms with respect to the rolling direction of the rolling pallet when unloading the at least one container.

According to the invention, it is then provided that

c) the loading surface of the rolling pallet is provided, at least in the region of the front edge, with a passage opening or with a recess open towards the front,

d) a discharge path having an unloading path floor is provided, the te seen when unloading in the rolling direction of the Roilpalet- te the storage space immediately, said pointing to the unloading end of Abladestreckenbodens is provided with at least one vertical Bodenausnehmung and at least one preferably stationary Abhebeelement, e) the at least one bottom recess for at least partially receiving the at least one seen in the rolling direction front roller of the rolling pallet and is designed such that when the rolling pallet is rolled along the unloading path in the direction of the unloading, the at least one front roller of the rolling pallet at least partially into the Dips in the bottom recess and thereby at least vertically lowers the front edge of the rolling pallet, f) the at least one preferably stationary lifting element is designed and arranged such that, at least as a result of the immersion of the at least one front roller in the bottom recess vertical lowering at least the front edge of the rolling pallet from below through the through hole or the front recess Loading surface passes through and in contact with a container bottom of the directly resting on the loading container and thereby the at least one container is lifted at least in the region of the front edge of the rolling pallet a bit far from the loading area and thereby occupies a first level,

g) the unloading point has a second level which is at most as high as the first level.

The bottom recess can for example be designed such that the rolling pallet at the end of the unloading path is essentially fixed solely by the (at least partial) immersion of the at least one front roller in the bottom recess and can not be moved further in the direction of the unloading.

In particular, the unloading station can be arranged at a production station at which workpieces and / or tools transported in the at least one container are required.

The advantage of the invention lies in the fact that the at least one container can easily be accomplished by an operator of the rolling pallet on the unloading place without much effort and without the use of further external forces, which would have to be generated by an additional lifting device, for example. The measures listed in the dependent claims advantageous refinements and improvements of claim 1 invention are possible.

Preferably, the second level of the unloading place is lower than the first level. Then, when the at least one front roller of the rolling pallet is submerged in the bottom recess, the at least one container can be easily pushed by an operator from the first higher level to the relatively lower second level of the unloading place. According to a development, the unloading station can have a flat discharge surface which is at least as large as a base surface of the at least one container. Then, the at least one container on the unloading surface can be completely, i. be laid with its entire surface lying on it. This then also applies to towers stacked containers.

Preferably, the unloading can have a flat Abladefläche, in which transverse to the rolling direction of the rolling pallet when rolling rolling blinds rolling elements are rotatably mounted. This facilitates moving the at least one container in the course of the unloading process, because then the container bottom of the (bottom) container can roll on the rolling or Wälzkörpem until it has reached its final position on the unloading.

Furthermore, a stop for the at least one front roller, which prevents further rolling of the rolling pallet in the direction of the unloading station when the at least one front roller is in the front of the bottom recess of Abladestreckenbodens at unloading in the rolling direction of the rolling pallet Bottom recess is diving. This ensures incorrect operation of the unloading system.

Preferably, a plurality of containers transportable by the rolling pallet can be provided which are stackable on the loading surface, the at least one lifting element coming into contact with the bottom of the lowermost container stacked on the loading surface when the at least one front roller enters the bottom recess is immersed.

In particular, the unloading path floor may have a first unloading path floor section and a second unloading path floor section adjoining the first unloading section floor section, the rolling pallet passing the first unloading path floor section during unloading and rolling toward the unloading station and the vertical floor recess passing to the unloading station is formed facing end of the second Abladestreckenbodenabschnitts, and wherein the rolling pallet is prevented by immersing the at least one front roller in the bottom recess on another rollers in the direction of unloading.

Further, the first unloading path floor portion may have a ramp rising when being unloaded in the rolling direction of the rolling pallet. This favors the formation of the at least one vertical bottom recess in the unloading path floor at the end of the unloading path, because then the level of the second unloading path floor section adjoining the first unloading path floor section is higher.

Furthermore, the second unloading path floor section may be formed flat and the vertical floor recess and the at least one lifting element may be arranged at its end facing the unloading point. The first unloading path floor section and / or the second unloading path floor section may also have lateral walls which, together with the first unloading path floor section and / or the second unloading path floor section, form a guide channel for the rolling pallet loaded with the at least one container during unloading. This facilitates guiding the rolling pallet along the unloading path.

Furthermore, a funnel-shaped widening of the side walls may be provided at an entrance of the unloading path to facilitate moving the rolling pallet into the unloading path. According to a development, the at least one lifting element may comprise a lifting roller or lifting roller which is designed and arranged such that upon immersion of the at least one front roller into the bottom recess the container bottom of the at least one container comes into contact with the unloading roller or the lifting roller and then the When moving from the loading surface of the rolling pallet toward the unloading place, at least one container can roll on at least one lifting roller or lifting roller. This facilitates moving the at least one container from the rolling pallet to the unloading place.

The at least one vertical bottom recess and the at least one stationary lifting element can be designed and arranged such that when the at least one front roller is immersed in the bottom recess, the at least one container still positioned on the loading surface is inclined towards the unloading point. Then, the at least one container can be moved even more easily from the rolling pallet on the unloading due to the then acting on him gravity. The invention also comprises a method for unloading at least one container transported on a loading surface of a rolling pallet from the rolling pallet to an unloading station by means of an unloading system according to at least one of the preceding claims, comprising at least the following steps:

a) positioning at least one container on the loading surface of the rolling pallet

b) moving the roller pallet loaded with the at least one container along the unloading path until the at least one front roller dips into the bottom recess and thereby the at least one container is lifted off the loading surface at least in the region of the front edge of the rolling pallet, c) Moving the at least one container in the direction of the unloading until the at least one container is unloaded on the unloading.

At least one of the above steps a), b) and c) can be performed by an operator directly and / or by a handling device.

If, in step b), the at least one container has assumed a position inclined towards the unloading surface, then preferably step c), namely moving the at least one container in the direction of the unloading station until at least one container is unloaded on the unloading station, is at least partially executed by the influence of gravity.

Description of the embodiment

In Fig.lA an embodiment of a rolling pallet 1 of an unloading system according to the invention is shown, which here, for example, four opposite a plane, for example, flat loading 2 for at least one container 4 rotatably mounted rollers, wherein two front rollers 6 and two rear rollers 8 are provided which preferably lie in each case in flight. As already stated above, the terms "front" and "rear" always refer to the position of the elements marked with these terms in relation to a rolling or unloading direction of the rolling pallet 1 during unloading, indicated by an arrow 10 in FIG at least a container 4. The loading area 2 of the rolling pallet 1 is formed here, for example, as a grid with a plurality of through openings, of which two through openings 12 in the region of a front edge 14 of the rolling pallet 1 are arranged.

FIG. 1B now shows the rolling pallet 1 as it is loaded with a plurality of containers 4 stacked on top of one another, with a flat container bottom 16 of a lowermost container 18 of the container 4, for example, contacting the loading surface 2. For example, the containers 4 are stacked on top of one another to form a container bundle 4, i.e., transversely transmitted. that lateral forces, which are exerted at any point of the container dressing 4, act on the entire container assembly 4. This can be realized for example by suitable connections between the individual containers 4.

2, an unloading section 20 is shown together with an unloading station 22 adjoining the unloading section 20 for the container 4 initially positioned on the rolling pallet 1. The unloading line 20 has an unloading path floor 24, which here also forms, for example, a floor of the unloading station 22 and may for example consist of one or more plates, which rests on the floor of a production hall.

Here, for example, the end 26 of the unloading path floor 24 pointing to the unloading point 22 has two vertical floor recesses 28 in transverse alignment, the transverse spacing of which corresponds to the transverse spacing of the two front rollers 6 of the rolling pallet 1. The vertical floor recesses 28 have dimensions such that the two front rollers 6 of the roller pallet 1 can at least partly dip into them and then the roller pallet 1 is held in such a way that further movement of the roller pallet 1 in the direction of the unloading station 22 is impossible. This can also be prevented by stops 30, which, for example, se are provided at the rolling or unloading 10 seen front ends of the Bodenausnehmungen 28.

Furthermore, two stationary lifting elements 32 are arranged, for example, at the end 26 of the unloading section 20 facing the unloading point 22, the arrangement and the spacing of the lifting elements 32 being selected so as to pass from below through a respective through opening 12 in the area of the front edge 14 of the rolling pallet 1 can protrude through. In this case, the lifting elements 32 each have two lifting rollers or lifting rollers 34 arranged one behind the other, which are mounted rotatably about axes which are transverse to the rolling or unloading direction 10 of the rolling pallet 1 in bearing blocks 35 arranged at the end 26 of the unloading section 20. Preferably, the lifting elements 32 are seen in the direction transverse to the rolling or unloading 10 seen between the two vertical Bodenausnehmungen 28 and are located approximately in alignment with these.

In particular, the unloading path floor 24 has a first unloading path floor section 36 and a second unloading path floor section 38 adjoining the first unloading path floor section 36, wherein the first unloading path floor section 36 has a ramp 40 rising when being unloaded in the rolling or unloading direction 10 of the rolling pallet 1. Thus, for example, the level of the second unloading land floor section 38 is higher than the level of the first unloading land floor section 36, as best seen in FIG.

Furthermore, the second unloading path floor section 38 is, for example, planar, with the vertical floor recesses 28 and the two lifting elements 32 being arranged at its end 26 facing the unloading point 22. The first unloading path floor section 36, the second unloading path floor section 38 and, for example, the unloading space 22 preferably have side walls 42 which, together with the first unloading path floor section 36, the second unloading path floor section 38 and the unloading station 22, form a guide channel for the containers 4 loaded with the containers 4 Form rolling pallet 1 during unloading.

At an input end 44 of the unloading path 20, a funnel-shaped extension 46 of the side walls 42 is also preferably provided to facilitate moving the rolling pallet 1 into the unloading path 20. The unloading station 22 may in particular be arranged at a production station to which workpieces and / or tools transported in the containers 4 are required.

Preferably, the unloading station 22 has a flat unloading surface 48, in which rolling elements 50, for example, are arranged transversely to the rolling or unloading direction. in the form of rollers in bearing blocks 52 are rotatably mounted.

By moving the rolling pallet 1 into and along the unloading path 20, the containers 4 are to be unloaded from the rolling pallet 1 onto the unloading station 22.

For this purpose, the roller pallet 1 loaded with the containers 4 is inserted into the input end 44 of the unloading section 20, for example by an operator 54, as illustrated by FIG. 4A. It is clear that a transverse force exerted on at least one of the upper containers of the stacked containers 4 by the operator 54 is also transmitted to the other containers and in particular to the lowermost container 18 and thus also to the rolling pallet 1, because the Container 4 for example with each other and also in relation to the rolling pallet 1 transverse force transfer stacked one above the other.

After passing the rising ramp 40 in the region of the first unloading section bottom section 36, the rolling pallet 1 is then pushed further, for example by the operator 54, into the second unloading path floor section 38, as shown in FIG. Then, when the two front rollers 6 of the rolling pallet 1 have reached the two vertical Bodenausnehmungen 28 then immerse the two front rollers 6 in this at least partially, resulting in a drop in the front edge 14 of the rolling pallet 1 and in Fig.4C and Fig .3 is illustrated.

The two stationary lift-off elements 32 are designed and arranged such that they pass through the passage openings 12 of the loading surface 2 from below as a result of the vertical lowering of the front edge 14 of the roller pallet 1 due to the immersion of the front rollers 6 into the floor recesses 28 and comes into contact with the container bottom 16 of the bottom surface of the container 2 directly resting on the bottom 18 and thereby the stacked container 4 are lifted at least in the region of the front edge 14 of the rolling pallet 1 a little way from the loading area 2 and thereby the container bottom 16 of the lowest container 18 assumes a first level h1. This situation is also illustrated in Fig. 3 and Fig. 4C.

It is easily conceivable on the basis of FIG. 1A that the loading area 2 of the rolling pallet 1 could also have one or more horizontally extending recesses instead of through openings 12 at the front edge 14, through which the two lifting elements 32 can protrude if the two front rollers 6 of the roller pallet 1 are immersed in the two Bodenausnehmungen 28 to contact the container bottom 16 of the lowermost container 18 and to lift it from the loading area 2. Furthermore, the vertical bottom recesses 28 and the two stationary lifting elements 32 are, for example, designed and arranged such that when the front rollers 6 are immersed in the bottom recesses 28, the containers 4 still positioned on the loading surface 2 are inclined at an angle a, for example Ablade are inclined towards, in particular Figure 3 illustrates.

Furthermore, the unloading station 22 has a second level h2, which is smaller than the first level h1, for example. The first level h1 and the second level h2 are measured, for example, from the floor 56 of the production hall on which the unloading path floor 24 rests.

If, according to FIGS. 3 and 4C, the rolling pallet 1 is located with the position still positioned on its loading surface 2 and in containers 4 inclined towards the unloading station 22, then it is easily conceivable that the containers 4 stacked one above the other according to FIG 4D can easily be moved by itself and without further action of the operator 54 in the direction of the unloading station 22, as indicated by the arrow 58 in FIG. 3, because the container bottom 16 of the lowermost container 18 extends along the two unloading rollers or Abhebewalzen 34 friction and the container bandage 4 under the influence of gravity from the first level h1 down and forward in the direction of unloading 22 can roll down to the second level h2 down. Having reached the unloading point 22 or the second level h2, the container bottom 16 of the lowermost container 18 can then roll further along the rolling bodies 50 mounted in the unloading surface 48 until an end position is reached, as shown in FIGS. 4E and 4F. In the end position can then be provided a stop for the container assembly 4, which prevents the container assembly 4 rolls over the unloading 22 out. The rolling pallet 1 unloading the containers 4 is moved during the rolling of the container assembly 4 in the direction of the unloading place 22 by the front rollers 6 immersed in the vertical floor recesses 28 and also by the stops 30 placed there in the position shown in FIG. 3 and FIG. 4C is also prevented from moving farther toward the unloading station 22, but may be easily pulled backwards and removed from the unloading path 20 by pulling by the operator 54.
