However, as shown in FIG. 4, when the tray 11 is supplied to the automatic warehouse 6 or the elevator, between the entrance 6b above the conveyor belt 2 and the processing device 4 closest to the automatic warehouse 6, and the conveyor belt 3 -17- (15) 200408597 between the port 6 a and the processing device 4 closest to the automatic warehouse 6 'the storage device 3 1 (33) is provided with the same mechanism of the storage device 43, 44' and the loading device 43 stacks the tray 1 1, 1 1 ..., and it is in a stowage state, and is supplied from the conveyor belt 2 to the automatic warehouse 6 (or elevator) in the state. From the automatic warehouse 6 (or elevator), the pallets 1 1, 1 1 ... are taken out under the stowage, and the pallets 11, 11 ... that are stowed are separately supplied to the conveyor belt 3 one by one in the aforementioned stowage § can. As described above, the conveying system 1 is constructed across the upper and lower floors of the workshop. The roller conveyor belts 2 and 3 are arranged on different floors above and below. By arranging the processing devices 4, 4 and the like along the conveyor belts 2, 3, the floor area can be reduced. The space can be installed, and the transportation system 1 can be constructed in a relatively narrow place to effectively respond to land conditions. However, the structure of the conveying system 1 is not limited to the implementation of the same floor as described above. The conveying means such as roller conveyors are arranged on the same floor, with one side as the return path and the other as the return path. The device is arranged in the order of the processing process. An automatic warehouse is interposed between the upper end of the forward path and the downstream end of the return path, and can be transferred between the upstream end and the downstream end of the return path. It is also possible to transfer the automatic warehouse between the downstream side end of the return path and the upstream side end of the return path between the downstream side end of the return path and the upstream side of the return path. Furthermore, in addition to the other automatic warehouses described above, it is possible to connect the upstream end of the return means and the upstream end of the return means by a roller conveyor. In addition, the downstream side end of the forward path and the upstream side end of the return path and the front cause are in this state, and the state is 44. When viewing the rollers, for example, when there are 2 paths and the upstream side, set another end. There is no particular limitation on the structure of the transfer means of the tray 1 1 between -18- (16) (16) 200408597. As described above, in the present invention, since the plate glass 10 is stored in the tray 11 and is transported in a protected state, the workpiece is not scratched, and the quality can be improved. Then, the unprocessed sheet glass 7 and 10 that have been transferred to the tray 11 1 stored in the automatic warehouse 5 are stored in the roller conveyor 2 and processed by the respective processing devices 4, 4 and the like to make the sheet glass 10 Finished goods. The finished pallet 11 is stored in the automated warehouse 5 from the roller conveyor 3, and the finished glass plate 10 is taken out of the pallet 11 and temporarily stored in the shed 5 in the automated warehouse 5. Furthermore, in The empty tray 11 contains new unprocessed workpieces 1 1 to the roller conveyor 2 and exits the warehouse. The trays 1 1 can be recycled. Therefore, after the finished product of the sheet glass 10 is transferred, a dedicated device for recycling the empty tray 11 is not required, and a reasonable transfer system 1 can be provided. However, the processing device 4 which is closest to the automatic warehouse 5 on the upstream side of the roller conveyor belt 2 is also used as a loading / unloading platform for receiving the sheet glass 10 between the system and the outside of the conveying system 1. Functional structure of an automated warehouse. Then, the processing device 4 closest to the automatic warehouse 51 is placed on the unprocessed plate glass 10 tray 1 1 and put on the roller conveyor 2 so that the plate glass 10 of the finished finished product is returned. Tray 11 is also available. In this case, before the processing device 4 (the lengthwise direction of the roller conveyor belt 2 is lateral), the untreated plate glass 10 is placed on the tray 1 1 and on the roller conveyor belt 2 in a protected state. It is conveyed to the downstream side and processed by each processing device 4, 4 ... to make the plate glass 10 finished product, and put -19- (17) (17) 200408597 on the return roller. The conveyor belt 3 is carried and is stored in the storage opening 5a of the automatic warehouse 5. The pallet 11 on which the finished finished products are placed is transferred by the stacker crane 50 to the exit 5b, and the exit 5b is directed toward the roller conveyor 2 of the road, that is, the automatic warehouse is passed from the upper floor to the lower floor. Within 5, the finished product is taken out from the tray 11 by the transfer robot 8 before the automatic warehouse 5 is closest to the processing device 4. At this time, the 'empty tray 11 is stored by the storage device 3 1 before the processing device, or the untreated plate glass 10 is transferred as it is, and the untreated plate glass 10 is placed on the tray 1 1. It is put on the roller conveyor 2. In this way, the trays 1 1, 1 1 ... can be recycled and reused. In this way, in the automatic warehouse 5, unprocessed plate glass 10, 10, ..., finished products of plate glass 10, 10, ..., and trays 1 1, 1 1 ..., this plate glass 1 0, 1 0 ... The finished products can be carried out together by a truck such as a truck, and the untreated sheet glass 10, 10, ... can also be carried together by a certain number of pieces by the truck. (Effects of the Invention) The present invention configured as described above can achieve the following effects. First of all, as in the invention of the first scope of the patent application, since the workpiece is stored in a transport container and transported in a protected state, the workpiece is not scratched and the quality can be improved. Furthermore, in the present invention, the unprocessed workpieces received in the transport container stored in the automatic warehouse are stored out of the way of the transporting means, and processed by each processing device to make the finished product. -20- (18) (18) 200408597 The finished container containing the workpiece is transferred from the return path of the conveying means to the automatic warehouse. The finished product is taken out of the transfer container or stored for the time being stored in the transfer container. In addition, in the empty transport container where the finished product of the workpiece is taken out, there is no need to provide a way to store the new unprocessed workpiece to the transport means. After the finished product of the workpiece is transported, it is recovered into an empty transport container. Dedicated handling equipment can be used to recycle containers and provide a reasonable handling system. Furthermore, in this invention, it is also possible to temporarily store unprocessed workpieces and transport containers in an automatic warehouse. In addition, as in the invention of the second patent application scope, in the second automatic warehouse, the transport container for accommodating the workpiece is located between the downstream end of the forward path of the conveyance means and the upstream end of the return path of the conveyance means. Can be transferred. In addition, as needed, it is also possible to temporarily store the transport container for storing the workpiece in the second automatic warehouse. For example, in the processing device arranged along the return path of the conveying means, the supply of workpieces is excessive, or in the front of the processing device, a large number of the processing containers in which the workpieces waiting to be processed are placed on standby are stored in the second automatic warehouse. Temporarily store the transport container containing the workpiece. In addition, if there is a limited-time item in a second-time automatic storage container that contains the workpiece, the limited-time item will be preferentially removed from the storage container, and the second-level automatic storage container can be transported as expected. Sequential delivery can improve operation efficiency.
