In particular, it should be noted that the drawings are schematic and may differ from the actual product. Descriptions of parts that are already known technology have been omitted.

[0021] <Case 1> 1 is a schematic diagram of a conveyance system related to a sorting station according to one embodiment of the present invention. As shown in Fig. 1, in the conveyance system 1 related to the sorting station where sorting work is performed, an overall control computer 100, a guide lamp 30, a first conveyor 40, and a first identifier reading sensor 60 are connected to each other wirelessly or via wire so as to be able to communicate with each other.

[0022] The overall control computer 100 comprises a CPU (Central Processing Unit), a ROM (Read Only Memory) that stores control programs that run on the CPU, and a RAM (Random Access Memory) that temporarily stores various data. The device may be a server.

[0023] The overall control computer 100 is comprised of a control unit that executes desired programs in the conveying system 1 associated with the sorting station; a communication unit that processes communications with devices constituting the conveying system 1, such as identifier information from the first identifier reading sensor 60, information related to drive control of the first conveyor 40, and information related to the illumination of the guide lamps; and a storage unit that performs processing related to the storage device. The storage device stores individual delivery information, such as delivery area and address, linked to order information such as the scheduled delivery date and ordered items. The individual delivery information is linked to delivery attributes such as delivery route and neighborhood information, such as residential area units, for example, block units, apartment units, or, in the case of large apartment buildings, floor units or building units. Priority (regular delivery, express delivery, etc.) and distinctions between refrigerated and frozen items using refrigerated shipping packs and regular delivery may also be linked to delivery attributes.

[0024] The overall control computer 100 controls a collection station located upstream of the sorting station to collect ordered items from individual homes according to a shipping plan, and sorts the ordered items into collection bags (see FIG. 2) made of plastic or the like stacked in a circulation box 10 for each individual home. The circulation box 10 and shipping pack 20 are then transported to the sorting station by a first conveyor 40. This process is controlled by the overall control computer 100. Basically, multiple collection bags S for individual homes are sorted into one shipping pack 20 on a regional basis (for example, within the same apartment building). However, this is not limited to this. An order from one individual home may contain multiple collection bags S, which cannot be contained in one shipping pack 20, and may be sorted into multiple shipping packs 20. A label with an identifier (an ID tag such as a two-dimensional code, RFID, etc.) is affixed to the circulation box 10 and / or the shipping pack 20.

[0025] The first identifier reading sensor 60 is installed upstream of the first conveyor 40 and near the first conveyor 40 relative to the worker P, and the guide lamp 30 is installed near the first conveyor 40 in conjunction with the transport positions of the circulation box 10 and shipping pack 20 so that it can be recognized by the worker P.
