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 readily by an operator of the rolling pallet on the unloading without much effort and without the use of other external forces, which would have to be generated, for example, by an additional lifting device, can be accomplished.

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 manually pushed by the operator from the first higher level to the comparatively 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 stored with its entire base surface. 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 during rolling rolling rolling or 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 rolling elements until it has reached its final position on the unloading.

Furthermore, a stop for the at least one front roller can be provided on a seen when unloading in the rolling direction of the rolling pallet front end of the bottom recess of Abladestreckenbodens, which prevents further rolling of the rolling pallet in the direction of the unloading when the immersed at least one front roller in the bottom recess is. 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, wherein the at least one lifting element comes into contact with the bottom of the lowermost container stacked on the loading surface when the at least one front roller is immersed in the bottom recess ,

Specifically, the unloading land floor may include a first unloading land floor section and a second unloading land floor section adjoining the first unloading land floor section, the rolling pallet passing the first unloading land floor section during unloading and rolling toward the unloading site, and the vertical bottom recess being formed at the unloading path-end end of the second unloading land floor section is, and wherein the rolling pallet is prevented by immersing the at least one front roller in the bottom recess on a further 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 Abladestreckenbodenabschnitt can be formed flat and arranged at its end pointing to the unloading the vertical bottom recess and the at least one lifting element.

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.

Description of the embodiment

In 1A is an embodiment of a rolling pallet 1 of an unloading system according to the invention, which here for example four compared to an example flat loading area 2 for at least one container 4 having rotatably mounted rollers, wherein two front rollers 6 and two rear wheels 8th are provided, which preferably each lie in alignment with each other. 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 4A through an arrow 10 indicated rolling or unloading the rolling pallet 1 when unloading the at least one container 4 , The loading area 2 the rolling pallet 1 Here, for example, is formed as a grid with a plurality of through holes, of which two through holes 12 in the area of a front edge 14 the rolling pallet 1 are arranged.

1B now shows the rolling pallet 1 as with several stacked containers 4 loaded, with an example, flat container bottom 16 a lowest container 18 the container 4 the loading area 2 contacted. The containers 4 For example, they are transverse force-transmitting to a container structure 4 stacked on top of each other, ie that lateral forces, which at any point of the container Association 4 be exercised on the entire container bandage 4 Act. This can be done, for example, by means of suitable plug connections between the individual containers 4 be realized.

In 2 is now an unloading route 20 along with one to the unloading route 20 subsequent unloading area 22 for the first on the rolling pallet 1 positioned container 4 shown. The unloading route 20 has a discharge conveyor floor 24 on, which here, for example, a floor of the unloading 22 forms and may for example consist in one or more plates, which rests on the floor of a production hall.

That to the unloading place 22 pointing end 26 of the unloading path floor 24 Here, for example, has two vertical Bodenausnehmungen located in the transverse flight 28 on, whose transverse distance to the transverse distance of the two front rollers 6 the rolling pallet 1 equivalent. The vertical floor recesses 28 have dimensions that the two front rollers 6 the rolling pallet 1 at least partially immersed in them and then the rolling pallet 1 is held to the extent that further movement of the rolling pallet 1 towards the unloading area 22 is impossible. This may also be due to attacks 30 prevented, for example, in the roll or unloading direction 10 seen front ends of the Bodenausnehmungen 28 are provided.

Furthermore, at the unloading place 22 pointing end 26 the unloading route 20 for example, two stationary lifting elements 32 arranged, the arrangement and the distance of the lifting elements 32 is chosen such that it from below through in each case one through opening 12 in the area of the front edge 14 the rolling pallet 1 can protrude through. The lifting elements 32 here each have two successively arranged Abheberollen or Abhebewalzen 34 on which in the end 26 the unloading route 20 arranged bearing blocks 35 are mounted rotatably about axes which transverse to the rolling or unloading direction 10 the rolling pallet 1 are. Preference is also the lifting elements 32 in the direction transverse to the rolling or unloading direction 10 seen between the two vertical Bodenausnehmungen 28 arranged and are about to escape to these.

In particular, the unloading path floor 24 a first unloading path floor section 36 and a second, to the first unloading path floor section 36 subsequent unloading path floor section 38 with the first unloading land floor section 36 one when unloading in roll or unload direction 10 the rolling pallet 1 seen rising ramp 40 having. Thus, for example, the level of the second unloading land floor section is 38 higher than the level of the first unloading path floor section 36 how best by 3 you can see.

Furthermore, the second unloading land floor section 38 for example, just trained, being at his to unloading 22 pointing end 26 the vertical floor recesses 28 and the two lifting elements 32 are arranged.

Preferably, the first unloading path floor section 36 , the second unloading roadway section 38 as well as, for example, the unloading area 22 side walls 42 which together with the first unloading path floor section 36 , the second unloading path floor section 38 and the unloading area 22 a guide channel for those with the containers 4 loaded rolling pallet 1 when unloading form.

At an entrance end 44 the unloading route 20 is also preferably a funnel-shaped extension 46 the side walls 42 provided to move the rolling pallet 1 in the unloading route 20 into it easier.

The unloading area 22 may in particular be arranged at a manufacturing station, in which in the containers 4 transported workpieces and / or tools are needed.

Preferably, the unloading point 22 a flat unloading area 48 on, in which transverse to the rolling or unloading rolling elements 50 eg in the form of rollers in bearing blocks 52 are rotatably mounted.

By moving the rolling pallet 1 in and along the unloading route 20 should now the container 4 from the rolling pallet 1 on the unloading place 22 be discharged.

This is done with the containers 4 loaded rolling pallet 1 in the entrance end 44 the unloading route 20 for example, by an operator 54 as pushed through 4A is illustrated. It is clear that a container stacked on at least one of the upper containers of the stacked container 4 from the operator 54 applied lateral force also on the other containers and in particular on the lowest container 18 and therefore also on the rolling pallet 1 is transferred because the containers 4 For example, with each other and in relation to the rolling pallet 1 transversely transferring stacked one above the other.

After passing the rising ramp 40 in the area of the first unloading path floor section 36 then becomes the rolling pallet 1 for example, by the operator 54 further into the second unloading path floor section 38 pushed, as in 4B is shown. If then the two front rollers 6 the rolling pallet 1 the two vertical Bodenausnehmungen 28 have reached then dive the two front wheels 6 in this at least partially, which is a drop in the front edge 14 the rolling pallet 1 pulls and in 4C and 3 is illustrated.

The two stationary lifting elements 32 are formed and arranged so that they at a result of the immersion of the front rollers 6 in the Bodenausnehmungen 28 conditional vertical lowering of the leading edge 14 the rolling pallet 1 from below through the openings 12 the loading area 2 through and in contact with the container bottom 16 on the truck bed 2 immediately lying bottom container 18 occurs and thereby the stacked containers 4 at least in the area of the front edge 14 the rolling pallet 1 a bit far from the loading area 2 be lifted and thereby the container bottom 16 of the lowest container 18 assumes a first level h1. This situation is also in 3 and in 4C illustrated.

It is based on 1A easily imagined that the cargo area 2 the rolling pallet 1 instead of passage openings 12 at the front edge 14 could also have one or more horizontally extending recesses, through which then the two lifting elements 32 can protrude when the two front rollers 6 the rolling pallet 1 in the two Bodenausnehmungen 28 are immersed to the container bottom 16 of the lowest container 18 to contact and this from the truck bed 2 withdraw.

Furthermore, the vertical Bodenausnehmungen 28 and the two stationary lifting elements 32 For example, designed and arranged such that when the front rollers 6 in the Bodenausnehmungen 28 are immersed, who are still on the truck bed 2 positioned container 4 For example, are inclined by an angle α to the unloading, as in particular 3 illustrated.

Furthermore, the unloading point 22 a second level h2 for example, which is smaller than the first level h1 is. The first level h1 and the second level h2 for example, from the underground 56 measured from the production hall on which the unloading pit floor 24 rests.

If according to 3 and 4C the rolling pallet 1 with the ones still in their cargo area 2 positioned and in to the unloading area 22 tilted containers 4 is shown, it is easy to imagine that then stacked containers 4 according to 4D very easily by itself and without further intervention of the operator 54 towards the unloading area 22 to move, as indicated by the arrow 58 in 3 is indicated because the container bottom 16 of the lowest container 18 along the two lift rollers or take-off rollers 34 low friction and the container bandage 4 under the influence of gravity from the first level h1 down and forward in the direction of the unloading area 22 to the second level h2 can roll down. At the unloading place 22 or the second level h2 then reached the container bottom 16 of the lowest container 18 continue along the in the unloading area 48 mounted rolling elements 50 roll until an end position is reached, such as 4E and 4F demonstrate. In the final position can then be a stop for the container association 4 be provided, which prevents the container association 4 over the unloading place 22 rolls out.

The themselves the containers 4 unloading rolling pallet 1 is during rolling of the container bandage 4 in the direction of the unloading area 22 through the in the vertical Bodenausnehmungen 28 dipped front wheels 6 and also by the placements placed there 30 in the in 3 and in 4C prevented position, also in the direction of unloading 22 but can be moved by the operator 54 pulled out slightly pulled backwards and out of the unloading path 20 be removed.
