The vertical conveyor is preferably a different conveyor than the warehouse conveyor and/or spaced apart from the temporary warehouse conveyor.
The workpieces can be transported by means of the vertical transport device preferably without carrying out a processing step.
Preferably, the work piece can be transported from one level, in particular the treatment level or the additional level, to another level, in particular the additional level or the treatment level, by means of a vertical transport device. The layers can be arranged in particular directly next to one another, in particular directly overlapping one another. It may also be provided that one or more further layers are arranged between these layers.
The intermediate conveyor preferably has a fixed conveying path from which the processing stations, which are optionally arranged on additional levels, cannot be accessed.
The temporary storage preferably has one or more warehouse entry and/or warehouse exit storage aisles arranged on at least one additional level.
It may be advantageous for the vertical conveying means to connect two or more levels of the processing apparatus to each other for conveying the work pieces from one of the levels to one or more other of the levels. The vertical transport device preferably connects only one or more of the treatment levels of the treatment plant with only one or more of the additional levels.
In particular, it can be provided that the vertical transport device connects only two transfer stations to one another, one of which is arranged on the processing level and the other on the additional level.
For example, it can be provided that the vertical conveyor connects the AGV conveyor of the processing device on one of the processing levels of the processing device on the one hand with the intermediate conveyor on the other hand.

Detailed Description
The embodiment of the treatment device, which is indicated as a whole with 100 and is shown in fig. 1 to 4, is used for treating workpieces, in particular for painting vehicle bodies.
The treatment device 100 is thus in particular a painting device.
The processing apparatus 100 comprises a plurality of levels 102 for receiving components of the processing apparatus 100, in particular for receiving processing regions 104, each of which comprises one or more processing stations 106.
In the embodiment shown in fig. 1 to 4, the two levels 102 are configured as process levels 108.
Most or all of the processing stations 106 are disposed on these processing levels 108.
Two levels 102 of the processing device 100 are also provided, which are configured as additional levels 110.
The workpieces to be processed are transported through the deck 102 and across the deck by means of the transport means 112 of the processing apparatus 100.
The conveyor 112 comprises for this purpose different conveyor sections.
Each conveyor section is used for a specific conveying purpose and/or is designed as a specific conveyor type.
Each processing region 104 is provided with, for example, a region conveying device 114.
In the first processing level 108 shown in fig. 1, the workpieces are transported, for example, by means of an AGV conveyor 116, during which the workpieces are transported by means of freely, in particular autonomously, transport vehicles.
The AGV conveyor 116 may be disposed in a single processing area 104 or may be disposed across the processing area.
In the embodiment shown in fig. 1, an AGV conveyor 116 is provided for conveying workpieces in a plurality of processing zones 104.
As can also be gathered from fig. 1, the processing plant 100 comprises a temporary storage 118, which is configured in particular as an overhead warehouse 120.
The temporary stocker 118 includes a stocker conveyor 122 by which workpieces can be conveyed from and to a stocker site within the temporary stocker 118.
In addition, the magazine conveyor 122 is used to receive workpieces at a magazine lane 124 of the temporary magazine 118 and/or to output workpieces at an outbound magazine lane 126 of the temporary magazine 118.
In particular, a care-of station 128 of the processing apparatus 100 is provided at a care-of area, such as a warehouse entry aisle 124 and/or an off-warehouse aisle 126.
The transfer station 128 is capable of transferring workpieces from, among other things, a conveyor of a first conveyor type to a conveyor of the same conveyor type or of another conveyor type.
As can also be seen from fig. 1, the temporary storage 118 comprises, for example, a plurality of sections or areas, which are or can be connected to one another by means of the connection points 130.
The temporary storage 118 is thus able to exchange or transfer workpieces, in particular, within different areas or sections of the temporary storage 118.
The stocked workpieces can thus be transported particularly flexibly to different off-warehouse storage aisles 126.
Preferably, the temporary stocker 118 is used to transfer workpieces to other levels 102 of the processing tool 100.
The workpieces processed in the second processing level 108 (see fig. 3), in which they are supplied to the temporary stocker 118, can be transported to the first processing level 108 (see fig. 1) by means of the stocker conveyor 122, for example, in order to continue the processing of the workpieces in the first processing level 108.
As is clear from fig. 3 in particular, the treatment region 104 is arranged around a temporary storage 118.
In particular, the temporary storage 118 is preferably arranged between two treatment areas 104, at least with reference to the horizontal direction and with reference to at least one of the levels 102.
The temporary storage 118 can thus be integrated in a particularly simple manner into the processing installation 100 and can be accessed simply and flexibly at a plurality of locations, so that workpieces can be stored in the temporary storage 118 and removed from the temporary storage as required.
As can be seen in particular from fig. 1 and 3, two treatment levels 108 are shown, a plurality of warehouse entry and/or warehouse exit warehouse channels 124, 126 being provided on each treatment level 108. The number of storage lanes 124, 126, along with the layout of the storage conveyor 122, is decisive for the storage capacity, the delivery capacity, the storage speed and/or the delivery speed of the temporary storage 118.
Depending on the design and arrangement of the treatment area 104, the number of warehouse channels 124, 126 provided on the deck 102 may not be sufficient.
Accordingly, preferably one or more additional levels 110 may be used to provide other stocker channels 124, 126 for accessing the temporary stocker 118.
As is known in particular from the two additional levels 110 in fig. 2 and 4, the treatment installation 100 comprises for this purpose one or more vertical transport means 132 which connect the two or more levels 102 to one another.
It is therefore provided that a vertical conveyor 132 (see fig. 2) on the first additional level 110 connects this additional level 110 to the first treatment level 108 (see fig. 1).
In this case, a plurality of, for example six, warehouse-out warehouse channels 126 on the first additional level 110 are connected to one or more, for example two, transfer stations 128 on the first treatment level 108 by means of the vertical conveyor 132.
Thus, the number of workpieces that can be taken out of the temporary storage 118 within a predetermined time interval and can be supplied to the first processing level 108 can be significantly increased, e.g., doubled.
The vertical conveyor 132 need not be arranged here in a manner directly adjoining the temporary storage 118.
Instead, it may be provided that the vertical conveyor 132 is arranged at a distance from the temporary storage 118 and is connected thereto by means of an intermediate conveyor 134.
The intermediate conveyor 134 is, for example, a roller conveyor 136, which connects the vertical conveyor 132 with the warehouse-out warehouse aisle 126 on the first additional level 110 by means of a plurality of transverse shifters and/or turntables.
It may be provided that all workpieces to be supplied to the first process level 108 are supplied to the same process region 104.
In contrast, in the embodiment shown in fig. 1 to 4, it is provided that the workpieces which are drawn off from the warehouse-out aisle 126 on the first process level 108 on the one hand and the workpieces which are supplied to the first process level 108 from the first additional level 110 on the other hand by means of the vertical conveyor 132 are supplied to the process regions 104 which differ from one another.
As is evident in particular from fig. 3 and 4, further vertical conveyors 132 may be provided, for example for transferring workpieces from the processing region 104 on the second processing level 108 to an intermediate conveyor 134 on the second additional level 110.
The workpieces can then be transported from the vertical conveyor 132 to the warehouse-in aisle 124 of the temporary warehouse 128, which is arranged on the second additional level 110, by means of the intermediate conveyor 134 on the second additional level 110, and can finally be warehoused in the temporary warehouse 118.
The workpiece can thus be transported, in particular from one of the levels 102, to the adjacent level 102 by means of the two vertical transport devices 132 mentioned above.
Furthermore, further vertical transport devices 132, which are not described here, can be provided in order to transport the workpieces, in particular from one of the treatment levels 108 to another of the treatment levels 108.
The previously described embodiment of the conveyor device 112 together with the temporary storage device 118 enables, in particular, a concentration of the treatment stations 106 on the first treatment level 108, which are designed as treatment boxes 138, and a concentration of the treatment lines 140 on the second treatment level 108. In this case, the optimization of the warehousing and ex-warehousing of the workpieces in the temporary storage 118 enables a simple transport between the levels 102, a simple sorting of the workpieces for supply to the individual processing stations 106, and a flexible adaptation to different processing variants.
Further flexibility is obtained by arranging the temporary storage 118 within the processing apparatus 100 and using one or more additional levels 110 for warehousing work pieces into the temporary storage 118 and/or ex-warehouse from the temporary storage 118.
