Description

Detailed Description of the Invention (Industrial Application Field) The present invention provides a storage system for storing small articles such as small parts and electronic parts using vertical or horizontal circulation type movable shelves. The present invention relates to a pinking system that can be used to efficiently pick small items from the mobile shelves.

(Conventional technology and its problems) When order-picking a wide variety of small items such as small parts and electronic parts that are stored by type in storage shelves, conventional techniques often involve manual labor, and rationalization has been delayed. Ta. Of course, it was possible to introduce the above-mentioned circulating movable shelves, computers, electronic scales (counting scales), etc., but even if these devices were introduced individually, the labor-saving effect would not be large.

In particular, when picking all the small parts necessary to assemble a predetermined number of products that are assembled using multiple types of small parts, the required number of each type of small parts required per one unit of the specified product. The picking operation must be performed by calculating the total number of each type of small parts from the above, and even if this work is performed using the electronic scale, it is necessary to input the unit weight and the required number of pieces for each type. Calculation operations are required each time, making it difficult to perform the work efficiently and accurately.

(Means and effects for solving the problems) The present invention proposes two new small article picking systems to solve the above problems, the first of which is a mobile shelf system. The storage position of each product type and the unit weight of each product type are stored in a computer, and an electronic scale is installed near the retrieval work position of the movable shelf. 1. Search the stored information for the storage position and unit weight of the item to be dispatched from the selected product type, and automatically operate the movable shelf based on the search result to move the storage unit for the item to be dispatched to the item retrieval work position. It is characterized in that the unit weight is input into the electronic scale at the same time as the unit weight is called.

According to the system of the first invention, the worker who actually performs the order picking operation simply takes out the specified article from the storage section of the movable shelf that is automatically called to the article retrieval work position and places it on the electronic scale. Counting of the article is automatically performed based on the unit weight input to the electronic scale.

The second system is effective for pinking all the small parts necessary to assemble a predetermined number of products that are assembled using multiple types of small parts as described above. The storage location of parts for each product type, the required parts for each type of assembled product, and the required number of each part are stored in a computer, and an electronic scale is installed near the work position for taking out items from the movable shelf. , from the types of assembled products and the number of assembled products inputted at the time of shipping work, the types of all necessary parts and the total number of required parts for each part are calculated from the stored information, and the storage position of each part is searched. Based on the search results, the movable shelf is automatically operated to call the necessary parts to the article retrieval work position, and the total number of the called parts obtained by the calculation process is displayed, and the retrieval work for the necessary parts is completed. The present invention is characterized in that the operation causes the next component to be called and the above-mentioned display for that component to be performed.

According to this second system, the worker who actually performs the order picking work takes out the specified parts from the storage section of the movable shelf that is automatically called to the work position for picking up the goods, and then picks up the specified parts from the display section or The electronic scale may be used to count the total number or total weight displayed on a separately installed display means. Once the necessary number of parts have been picked for the - part, the next necessary part will be called out in the same way just by performing the work completion operation, so the counting work using the electronic scale will be performed on the part in the same way. By repeating the same steps below,
All the parts needed to assemble a given number of a given product can be collected.

(Example) The present invention will be described in detail below, but first, equipment for carrying out the present invention will be described based on FIG.

In this state, the article with the corresponding product number is placed in the tray 11 of the electronic scale 10 from the storage section 6 indicated by the lit indicator light 7.
When placed on the tray 11, the electronic scale 10 calculates the number of items on the tray 11 based on the input unit weight from the total weight of the items on the tray 11, and displays the number on the display unit 13. The amount of articles on the receiving tray 11 is adjusted so that the number of articles displayed in the delivery section 13 (the number instructed by the delivery slip) is reached. Of course, the remaining items are returned to the original storage layer.

When the specified number of goods have been dispatched for the article corresponding to the first product number in the dispatch work data as described above, by turning on the work completion switch 9, the process corresponding to the second product number in the dispatch work data is completed. The storage section 6 of the storage section layer is called to the loading/unloading operation opening 5, the corresponding indicator light 7 is turned on, and the product number, unit weight, and number of items to be shipped are sent from the computer 14 to the electronic scale 10. All you have to do is take out the item with the item number as described above. When inputting the outgoing work data to the computer 14, the number of outgoing items for each item number is also input, and this number of outgoing items is also sent to the electronic scale 1.
0 on the display unit 13, but since the number of items to be delivered can be known from the description in the shipping slip, it is possible to omit inputting the number of items to be delivered. Further, when inputting the number of items to be delivered, the number of items to be delivered can be displayed on a separate display means provided on the movable shelf 1 or any other arbitrary position when the indicator light 7 is turned on. This display means can be provided at a location corresponding to each of the plurality of storage sections 6 that are simultaneously called out to the entry/exit operation opening 5, for example, at a location adjacent to each indicator light 7.

Next, an embodiment of the second invention using the equipment shown in FIG. 1 will be described in detail. Each storage section 6 in the movable shelf 1 stores parts of a specific type. computer 1
On the front side of 4, there is part configuration data consisting of the part numbers of parts required for each type of assembled product, the required number of parts for each part number, and the part unit weight for each part number, and the storage area for each part number. The layer settings are memorized.

Setting of warehousing work data and warehousing work are performed in the same manner as in the embodiment of the first invention.

The shipping work, that is, the order picking work can be performed as follows. First, according to the delivery slip, the keyboard 15
1tkl (type) of product and the number of assembled pieces (lot number) are input into the computer 14 in sequence. computer 1
4. From the above parts composition data, for each product floor, the part number of the necessary part, its storage layer, the total number of parts required for each part number (number of parts required per product x number of assembled parts), and Search and calculate the component unit weight for each product number, and subtract and correct the inventory amount for each product number as necessary. At this time, the display unit 16 can display the setting data or information obtained by search and calculation in addition to the setting data. In addition, when the unloading work is performed in order of storage location, the setting data can be rearranged in the order of storage location on the computer 14. The picking work after the setting of the unloading work data is completed according to the embodiment of the first invention. Similarly, the process is performed as shown in flowcharts 1 to 1 in FIG.

That is, when the work start switch 8 of the movable shelf 1 is turned on, the driving means 2 of the movable shelf 1 operates according to instructions from the computer 14, and the shelf unit 3 rotates to move to the first item number in the shipping work data. The storage section 6 of the corresponding storage section pigeon is called to the entry/exit operation opening 5, and the indicator light 7 located directly above the storage section 6 to be removed is turned on by a command from the computer 14. computer 1 at the same time
4, the product number, unit weight, and number of items to be shipped are sent to the electronic scale 10 and displayed on the display section 13. In this state, the parts with the relevant part number are placed in the tray 11 of the electronic scale 10 from the storage section 6 indicated by the lit indicator light 7.
When placed on the tray 11, the electronic scale 10 calculates the number of items on the tray 11 based on the input unit weight from the total weight of the items on the tray 11, and displays the number on the display unit 13. The amount of items on the receiving tray 11 is adjusted so that the number of items to be delivered is the number displayed in the section 13 (number of parts per product x number of assembled products). Of course, the remaining items are returned to the original storage section 6.

When the specified number of goods have been dispatched for the article corresponding to the first product number in the dispatch work data as described above, by turning on the work completion switch 9, the process corresponding to the second product number in the dispatch work data is completed. The storage section 6 in the storage section is called to the loading/unloading operation opening 5, the corresponding indicator light 7 is turned on, and the product number, unit weight, and number of items to be shipped are sent from the computer 14 to the electronic scale 10. All you have to do is take out the item with the item number as described above. By repeating this pinking process, once all the parts necessary to assemble a predetermined number of products of a predetermined type have been collected, the same procedure as above is performed based on the shipping data entered for the next type of product. Can perform pinking work.

When calculating the number of parts to be delivered for each part number, the lower limit is the total number of parts determined by the number of parts required per product x the number of assembled products, and the upper limit is the number obtained by multiplying this by an appropriate premium rate. As a value, this householder may be displayed by a display means provided on the electronic scale 10 or the movable shelf 1 side, or by a display means provided independently.

In the movable shelf 1 of the embodiment, since a plurality of storage units 6 are simultaneously called out to the opening 5 for loading/unloading operations, an indicator light 7 is provided to indicate which storage unit 6 is the target of loading/unloading operations. 7 may be omitted.Of course, it is also possible to use a movable shelf in which only one storage section 6 is called out to the opening 5 for loading and unloading operations.

(Effects of the Invention) As described above, according to the picking system of the present invention (first invention), the worker who actually performs order picking automatically moves to the article retrieval work position (in the embodiment, the opening for loading/unloading work). By simply taking out a specified article from the storage section of the mobile shelf called in section 5) and placing it on the electronic scale, the article will be counted automatically based on the unit weight input to the electronic scale, and then taken out. There is no need to operate the movable shelves each time based on the type of item, or calculate the unit weight and set it on the electronic scale. It is possible to efficiently and accurately perform order peering work from a variety of stored canes.

Further, according to the pinking system of the second invention, when performing a picking operation to collect all the parts necessary to assemble a predetermined number of predetermined products, the parts configuration data for each type of product (the part number and part number of the necessary parts) is collected. At the time of shipping work, workers artificially calculate the part number and number of parts required for each type of product according to the number of assembled products, and create a shipping work list based on the number of items). There is no need to manually operate the movable shelves according to the delivery work list, and the pinking work can be performed extremely efficiently and accurately.
