Description

  The present invention relates to a product storage system, and is particularly suitable for a product storage system that stores a product in a predetermined storage area.

  There is a wide range of logistics service operations where logistics companies collectively carry out custody operations for custody and storage of customer products and delivery operations for transporting custody products to designated destinations based on customer instructions. . In this logistics service business, once the delivery destination of the stored product is determined, pick up the stored product for each delivery destination or every delivery route before the scheduled delivery date or immediately before delivery. A shipping picking operation is performed.

  In this shipment picking work, the worker confirms the individual product such as the product name and product code of the product to be searched using the storage location information of the stored product as a clue, so that the product can be picked without fail. Required. That is, the confirmation work is performed by visually confirming the exterior display by the operator himself or by displaying information for identifying the individual product (for example, when a barcode label is affixed or printed, this barcode label ) At a reading terminal (for example, a barcode reading terminal).

  Conventionally, the product storage position information, which is a clue to search for products, is transported to the storage position when the product is received, and left by the worker who has placed it in his / her memory, or the address indicating the storage position is determined and stored in advance. Sometimes the address is registered in the inventory management system.

  The latter is an operation method called a fixed location or storage address method, and there is an advantage that a product can be searched for by using the address as a clue to a person other than the storage worker. This product storage information is a collective management of product information such as the product name, product code and quantity of the product itself, and storage location information such as addresses, etc., which are collectively referred to as inventory management. It is called the system, and it is used and distributed by many logistics companies. In addition, as a patent document regarding an inventory management system, there exists Unexamined-Japanese-Patent No. 2002-356227 (patent document 1), for example.

JP 2002-356227 A

  However, in the conventional inventory management system, since the worker himself inputs the storage address, there is a possibility that an input error occurs. In addition, in the conventional inventory management system, it is not necessary to synchronize the work for placing the product at the storage position and the timing for registering and inputting the storage address, so that the storage address is not registered and input in synchronization with the completion of the storage. It was possible to enter the storage address before the storage or after a considerable time from the completion of the storage. For this reason, there is a possibility that a difference occurs between the actually stored position and storage time and the storage position and storage time input to the inventory management system. In addition, in an area where products are stored (for example, in a warehouse), the stored products are frequently moved and rearranged frequently for the purpose of organizing and organizing the stored products and improving storage efficiency. In warehouses where storage addresses are completely managed, it is necessary to re-enter storage location information every time a product is moved or rearranged, which is a heavy burden for logistics companies and storage workers. This also caused a difference between the storage address registered in the inventory management system and the storage address registered in the inventory management system, which was a major operational problem.

  Therefore, in these inventory management systems for warehouses with completely managed storage addresses, the area of storage addresses is allocated a little larger, and even for minor movements and rearrangements, each area is large enough to be handled as movement within the same storage address. In many cases, a device for assigning a storage address is taken. However, as the storage address becomes wider, the meaning of information as a clue to search for a product at the time of shipping picking work is diminished, and a new problem has arisen that cannot be performed efficiently.

  Therefore, it is desirable to know the product position in detail, to obtain a storage address that does not burden the actual warehousing work, and to input the storage position in synchronization with the product storage work that does not depend on the operator's input. Yes. In other words, there is a mechanism that allows storage addresses to be registered when the products are stored while maintaining the storage address area allocation that is useful for actually searching for stored products, and a minor issue that occurs due to reasons such as organizing and ordering in the warehouse. Construction of a product storage system with high flexibility that can easily cope with storage address changes during simple movement is desired.

  In addition, for products that have a significant management responsibility, such as medical materials and drugs, the slight movement of products in the warehouse is constantly monitored, and workers in the warehouse and product managers are responsible for the stored products in the warehouse. It is necessary to monitor the act of approaching itself and ensure the safety of stored products. In other words, in such a warehouse, it is necessary to sufficiently manage the dynamic monitoring of workers, etc., and the functions of the inventory management system described above include attendance information and current location of workers and product managers in the warehouse. It is desired to add a function of a work management system that is constantly grasped and to build a product storage system that integrates an inventory management system and a work management system.

This onset Ming purpose, storage products and current position working in the storage location's and of product management responsible for the dynamics can be accurately recognized efficiently, it is efficiently and reliably shipped picking work can be a highly secure storage It is to provide a possible product storage system.

It has a function of generating information for displaying the storage position of the stored product 4a and the current positions of the work terminals 2A and 2B on the screen of the work terminal with wireless communication function 2B.

  And, in the logistics process of delivering products such as medical materials and pharmaceuticals from the manufacturing location to the use location such as medical institutions, the manufacturers themselves consign storage and transport operations to a specialized logistics company instead of transporting directly to the use location. As a result, logistics are becoming more efficient. However, in the case of medical materials and pharmaceuticals, even if the distribution is outsourced, the quality control in this distribution process must be strictly controlled by the manufacturer and the seller. In other words, regarding the management aspects of safety, security, and quality other than actual logistics work, it is required that manufacturers and sellers perform quality control. In particular, in a warehouse as a storage location, a pharmacist must be working as a manager and is an important quality control issue. As in this example, centralized management of pharmacist work status and product storage information ensures that quality control is observed automatically and without information. This is an effective system.

  In addition, for medical materials and pharmaceuticals that require strict management standards, theft and misdelivery in the logistics process may lead to accidents, so manufacturers and sellers outsource logistics. Instead, it was common to deliver directly to users of medical institutions. Therefore, there has been a problem that excessive transportation costs are required. Therefore, in this embodiment, the management server 6 includes an inventory management system that collectively manages product information and product storage information, and a work management system for workers including workers and product managers. The product management information and the location information of the product manager are centrally managed by combining the work information and location information of the product management manager with the product inventory management information. As a result, even for medical materials and pharmaceuticals that require strict management, it is possible to outsource distribution and realize a product storage system that can be safely and securely stored, reducing distribution costs and enhancing quality control. Can be realized simultaneously.

  In the present embodiment, the management server 6 simultaneously records product information, product location information, and current date and time based on information from the wireless tag 4, constantly monitors the product storage location, and uses the work terminal 2A. When performing communication processing for reading product information of the stored product 4a and registering the product information in the management server 6, the current location information of the work terminal 2A is included in the product information as product placement location information in the management server. I am trying to register. As a result, it is possible to prove the authenticity of whether or not the actual state of the stored work actually existed. In other words, depending on the product to be stored, there is no doubt that you want someone other than the worker who performed the storage work to prove that the product was stored at that time on that date. Because there is.

  According to the present embodiment, the management server 6 recognizes the position of the stored product 4a based on the information of the wireless tag 4 transmitted through the relay device 5, and subdivides the position information of the stored product 4a into the product storage area. Since it is configured to transmit to the work terminals 2A and 2B through the relay device 5 in association with the stored storage address information, the current position of the stored product 4a can be accurately and efficiently recognized, and the picking operation can be performed efficiently and reliably. It can be a product storage system.

  Further, the management server 6 recognizes the positions of the work terminals 2A and 2B based on the information of the work terminals 2A and 2B transmitted through the relay device 5, and the information of the responsible mobile terminal 3 transmitted through the relay device 5 Based on the position of the person-in-charge portable terminal 3, and the safety of the storage work is determined based on the recognized positions of the work terminals 2A and 2B and the person-in-charge portable terminal 3. It is possible to make a product storage system capable of accurately recognizing a person's behavior and capable of highly safe storage.

Furthermore, the following specific effects can be obtained by the configuration of the embodiment described above.
(1) The storage position can be automatically recognized and registered in the inventory management system.
(2) When a wireless tag is attached to a stored product, it is possible to automatically track the position of the product and re-register the product storage position even when the stored product frequently moves.
