Commission cabin.

The invention relates to a high-bay warehouse with an integrated in a shelf truck commissioning cabin.

The rational storage of goods, articles, etc. led to the development of unified storage units, for. Example, on pallets, as these, that are interchangeable between producer, carrier and dealer. It is in this case, the term "pallets" inter alia to 15149 summarized in DIN 15141 agent such as stacking plates (pallets), stacking containers (box pallets), boxes, mesh box pallets (stacks Grid container), stanchion and pallets, but also other palletizable institutions understood ,

The use of such pallets on the one hand led to the creation of warehouses with the construction and dimensions of the standard palettes largely matched shelves, on the other hand to such shelves, in which the load units are accessible to Kommissionierungszwecken.

For goods storage conditions in which trucks with a stack height of no more than 7m have to 11m no longer proven Stacker cranes economically, it is the so-called "high-bay warehouses", whose bearing height can be adjusted to the economy, passed.

Such high-bay warehouse operated today mostly automatically, either located in the actual storage space not a human person, and the high-bay warehouse is operated by controlled stacker cranes by done all loading and unloading processes with these vehicles or to traffic with stacker vehicles in which persons of monitoring are storage and retrieval process or picking purposes.

In fully automatic mode, a picking station in the high-bay warehouse is in any case also set up, since the rack stacker crane receives a pallet, but not all of the material located on this range is required. Thus, the rack stacker crane shall, after the command prompt returns the path to Palettierort, the picking location and back to the original Palettierort. Depending on the type of goods and driving frequency such routes may become a Unwirtschaftlichkeitsfaktor.

If different pallet sizes to be stored in such a storage facility, the vehicle Additional safety devices, such. As to pass under control profile.

It is thus based on the finding that the efficiency of warehouses is also dependent on the internal organization. Not only the optimal storage but also the flow of goods is to be considered of the profitability of a bearing, ie unnecessary ways of conveying vehicles during storage and removal as well as during order picking can lead to inefficiency of a bearing.

As technical equipment is therefore such Regal trucks have proved expedient which have a built-picking, so that the Palettiergut must not be transported by Palettierort to a picking location, but may be the on-site commissioning.

Here arise naturally difficulties that result from safety requirements, construction conditions and manner of storage. On the one hand, the possible extent of a shelf lane and the Schattenmaß the stacker vehicle noted on the other hand, the clearance between rack stacker crane and rack must a minimum and maximum not exceed or fall short on safety grounds.

A minimum distance between A conveyor and shelf must already be therefore given to ensure that the stacker cranes do not collide during fast driving through the aisles with improperly einpalettierten goods.

The maximum distance between A conveyor and shelf may due to the risk of falling, which is subject to the operator, are not exceeded.

However, these technical and safety standards are reflected in the ergonomics negative effect, ie due to the required minimum and maximum distances are various different factors in the accessibility of the operators to the shelves a negative.

From AT-PS 354 937 a shelf operating device is known which is constructed such that a free access is given to the shelves. But even this largely optimized design is still not satisfactory in terms of accessibility to the shelves by the operator.

So here too there remains the problem of the minimum and maximum distances between storage and retrieval machine and shelving.

The shelves themselves have to be constructed so that the Palettiergut is embedded with its longitudinal side the shelf vehicle. This means an enormous space taking and an extremely unfavorable rack structure.

From DE-A-33 14 495, a storage and retrieval unit for a high-bay warehouse is known, which consists essentially of a horizontally and vertically movable carriage which carries a lift cage for an operator and a pallet gripper. The gripper can be swiveled, and up and down, so that the operator can process the carriage at any desired point of the shelf in the elevator car, drag there by means of the gripping device, the pallet with the desired goods from the shelf, drive up close to the elevator car and can remove the desired amount of goods the pallet and stored in the elevator car. This elevator car thus represents a kind of commissioning cabin.

The picking of this prior art, however, such work is evident, very costly and time consuming; located a quick and easy, direct access to the operator to have the shelf, palletized goods is not possible here. According to this prior art, it is difficult, if not impossible, that pallets of various types in one and the same high-bay warehouse to be stored, as the gripping device must match the respective pallets.

Furthermore, due to the limited space for the rotational movement of the gripping means necessary, to classify the pallets in the shelf that its longitudinal axis is parallel to the shelf; space utilization is thus greatly improved.

The present invention is therefore an object to provide a commissioning cabin for high-bay warehouse trucks, wherein the workspace and motion range is made ​​variable, ie the cab is verschmälerbar while driving to the prescribed level, and at the site is so extendable, so that the accessibility to the shelves and thus added to the Palettiergut is, the gaps between the vehicle and rack are closed by retractable means broadens the cabin, so that increases the access area, and thus the Palettiergut with its longitudinal side in the depth of the shelf, thus saving space can be stored, and in order to allow a convenient rack structure.

These objects are achieved by the indicator of Anspuchs. 1

Particular embodiments of the invention are characterized in the dependent claims, the commissioning cabin invention for high-bay warehouse, which is integrated into a stacker crane, and a driving operation status, access area and the cargo area which is designed such that the commissioning cabin which at least one of the shelves or in tramline ostensive sides is formed of being spread.

A preferred embodiment provides this before, that the commissioning cabin a driving operation state, the access area and the cargo area surrounding and this captive railing, said railing is designed at least partly tiltable shelf direction or horizontally in Regal direction extendible, the railing on one, from the bottom of the commissioning cabin extendable bottom part is arranged, which performs the same extension device as the railing to close the existing between stacker crane and stockout.

Alternatively, there is also the possibility, represented horizontally or extendable to form or to achieve the expansion of the commissioning cabin, characterized in that to provide a combined horizontal extensibility with tiltable bottom of the commissioning cabin railing to.

To limit the safety of the working area not only to the access area and the navigation station, provides the present invention, that railing telescopically extendable and retractable form, so that it can be retracted and extended across the cargo area.

On the basis of the accompanying drawings, which show particularly preferred embodiments of the invention, this will now be explained in more detail.

Figure 1 shows a perspective view of a known pallet high bay warehouse. There are in this illustration, the shelves 2 seen in which the Palettiergut located. 13 Based on the goods receipt 15 and 16 the Palettiergut 13 is provided on the conveyors 20 to be received by the stacker cranes 19th The stacker cranes 19 are, as shown here, usually on rails installed in the lane 3 between the shelves. 2

Conventionally, the stacker cranes 19 are designed such that they function up to a height of 30m for storage and retrieval of entire storage units in the high-bay warehouse. After the swap, the stacker crane travels to the conveyor system 20, from which the item is being conducted in the arrow direction to an external order picking 14th

Once the part commodity is removed from Palettiergut 13, this 15, 16 fed back via one of the receipts to the high-bay warehouse, which is always again have to go through a Palettenprüfeinrichtung 17 to be optionally separated by the discharge station 18 by the conveyor 20th

As can be seen also from the figures 2 and 3, the rack conveyer 19 passes through this great way, which is why it should be with the present invention, inter alia, avoiding, to pick externally, ie to provide a stacker crane, which acts as a commissioning cabin at the same time. With conventional stacker cranes, this is also for safety reasons, only high-bay warehouses up to a height of 12m possible.

Under picking is understood here in a camp for the compilation of an order generally collecting items from an assortment. It is with the present invention also an efficient picking, ie an optimal numerical removal of articles per unit time over a static provision (the Picker is a commodity) to achieve, because the knowledge is based, that the dynamic provisioning, ie the goods come to picker, for certain storage products is uneconomical.

A particular advantage of the present invention is that the Palettiergut 13 can be stored in the depth, ie, the Palettiergut 13 is with its longitudinal side 21 inserted into the shelf 2 so that the broad side 22 facing in the rack aisle. 3 This arrangement is illustrated in FIG. 2 and 3

Here is the storage of palletized 13 in the shelves 2, as previously shown, while in the right side shelf 2a the Palettiergut 13 still so used in the shelves, that the longitudinal side 21 facing the aisle. 3

The importance of the spatial arrangement of the palletized 13 in the shelves 2 resulted partly from the fact that in the case of Einpalettierung of palletized 13 with the longitudinal side 21 to the shelf depth a statically favorable shelf construction is possible and on the other hand of the product currently on the Palettiergut 13 even for is the picker achievable if the commissioning cabin according to the invention, as described, is formed.

As I said, that the Einpalettierung is favorable for the statics of the rack structure in the depth of the shelves, as well as for the use of space of the bearing.

4 shows such an arrangement of palletized 13 is shown on the shelf. 2

It is now clear that the Einzelpalettiergut is difficult to access for the pickers 13a an open pallet 13, as between commissioning cabin 1 and rack 2 a certain safety distance 23 is observed, and thus it is not possible from danger grounds that the picker the single goods 13a reaches in the shelf center 24, which is why the Palettiergut was 13 conventionally incorporated Recalling with its longitudinal side 21 to the tramlines. 3

With the present invention, it is possible to bridge the clearance distance 23 by means of an extendable base part 12, as shown in phantom. Additionally or alternatively, it is possible the railing 10 at least partially tilted form, so that the access area will be further expanded.

Figures 5, 6 and 7 show the commissioning cabin according to the invention in a particularly preferred embodiment.

The commissioning cabin 1 is here first with a known rack conveyer 19 to compare and includes accordingly all safety equipment, such as roof covering 25, 26 escape ladder and so on.

In the back third of the commissioning cabin 1 is the driving control station 7 and the front third of the cargo area. 9

Depending on the position of the railing 10 of the access area 8 is reduced or enlarged over the cargo area 9 also. Once the picking order is present, the commissioning cabin 1 is controlled in the appropriate aisle 3, until it has reached the corresponding first Palettierort. Can then proceed with the invention commissioning cabin 1, the following process:

If the cargo area 9 is free, the railing 10 can first be telescopically extended in the direction of arrow 27th The starting position is initially shown in phantom in FIG. 7 It is also apparent that a crossbeam is arranged 10a of the railing between the cargo area and access area for separating the access area first. In the extended position (-..-) (dash-two dots) is extended to above the cargo area, the telescope-shaped railing 10th Thus, an extended access area is created which is well secured. In order to extend the working range of the commissioning cabin 1 in addition, there is the possibility, the railing 10 can be tilted to form, as shown in Figure 6 is clearly visible.

Thus, the order picker can also bend over the commissioning cabin 1, since the gap or the safety distance 23 between 1 and commissioning cabin shelf is 2 bridges. Additionally or alternatively, it is also possible for the bottom 11 of the commissioning cabin 1 retractable form, so that a bottom portion 12 extends from the bottom 11 of the commissioning cabin 1 so as to close the safety distance 23 also spatially.

For this purpose, it has proved to be useful to divide the rail 10, so that this is also to tilt only in part if such. As a gap in Palettierort present, as shown in Figure 4, so that the picker partially laterally on the Palettiergut can zoom access. 13

Of course, the commissioning cabin 1 of the invention is equipped with, for. Example, optical monitoring units, so that the undercarriage is blocked in ausgeweitetem picking area.

With the present invention a commissioning cabin is provided which optimizes the picking work in ergonomic and safety issues, as the order picking is no longer affected by the existing and required safety because the workspace on picking / Palettierort is adapted to the particular circumstances.
