Description

Description: TECHNICAL FIELD The present invention relates to a picking system for taking out a predetermined number of different kinds of articles stored in shelves divided into a plurality of articles.

(Prior Art) A slanted shelf board is used, and the shelf positions facing the front are used as individual article storage positions, and the slanted shelf is used to remove the front article case and remove the new case from the rear. An order picking system that uses fluidized shelves with a structure that appears at the front, arranges a large number of these in the article storage area, and a worker picks up a predetermined number of goods of a predetermined type one after another according to an order list. It has been known.

FIG. 2 is a schematic configuration diagram of a fluidized shelf used in the picking system already proposed in JP-A-57-145704. In the figure, a fluidized shelf 10 has a plurality of shelves 11 inclined forward, and a case 13 in which different articles 12 are accommodated is arranged on each shelf. The necessary product 12 is taken out from the case 13 located on the front of the shelf, and when the case becomes empty, the case is removed so that the next case comes out to the front of the shelf. As shown in FIG. 3, such a fluidized shelf 10 is arranged so as to face the belt conveyor 14, and an operator places the taken out article on the belt conveyor and conveys it to the pickup position. The reference numeral 15 designates a pallet storage shelf that stores replenishment items for the fluidized shelf.

In FIG. 2, an item indicating lamp 16 is provided for each case arrangement position of the shelf 11, and the operator is informed of the position of the shelf from which the article should be taken out by lighting the item indicating lamp 16. In addition, a digital indicator 17 that displays the number of items to be removed is displayed in the center of the upper part of the fluidized shelf.
Further, a push button switch 18 that is operated when the removal of the article is completed is provided on the side of the fluidized shelf.

(Problems to be Solved by the Invention) In such a picking system, it is required that the fluidized shelves always have an appropriate amount of articles arranged therein. Therefore, the worker regularly checks the actual inventory amount based on the inventory list issued by the computer. By the way, a large-scale distribution center or backyard usually has a large number of fluidized shelves, and there is a problem that the above-mentioned work of checking the inventory amount is complicated and time-consuming.

Therefore, the present invention provides a picking system aiming at solving the problems of the prior art.

(Means for Solving Problems) The picking system of the present invention is configured as follows. That is, it has a plurality of shelves, arranges a plurality of types of articles at predetermined positions on each shelf, and displays a means for managing the inventory amount of each article accommodated in each shelf and the number of each article taken out. In a picking system for picking up a designated article, including display means, means for outputting the inventory quantity of the designated article to the display means, the inventory quantity of the displayed article, and the actual inventory of the designated article. A switch provided at a predetermined position where each article of each shelf is operated when the quantity is equal, the inventory quantity of the displayed article and the actual inventory quantity of the designated article are different. Input means for inputting data such as the code of the article and the actual inventory amount, etc., and the inventory quantity of the article for which the signal of the switch is monitored and the signal is sent is not corrected, and is input from the input means. Inventory of relevant items by reading information A picking system, characterized in that comprising a correction means for correcting a.

(Operation) With the above configuration, according to the present invention,
Inventory management of the articles stored in the shelves can be performed quickly and accurately.

Example An example of the present invention will be described below with reference to the drawings. First
The figure is a schematic configuration diagram of the present invention. In the figure, the fluidized shelves 10 ₁ to 10 _n having the structure described in FIG. 2 are arranged, and the containers C ₁ , C ₂ , ... C placed on the belt conveyor 14 conveyed in the arrow direction. _A specified number of items are taken out from the required number of shelves and packed in _n . Shelf controller 20 for each fluidized shelf
_{1 to} 20 _n are provided and connected to a control device 21 configured by a microcomputer or the like via a repeater 24. Ordering data such as the type and quantity of necessary articles for each store or delivery area is input to the control device 21 from an input device 25 using a keyboard or the like. The control device sends a signal to the shelf controller based on the order data to control the display of the position and quantity of the articles taken out from each fluidized shelf. In addition, a signal is output to the conveyor drive device 22 to control the start, transfer speed, stop, etc. of the belt conveyor. For the container containing the goods, a label issued by a label issuing machine 23 installed at a predetermined position of the belt conveyor is attached with a label on which the delivery destination, the code of the goods, the quantity, etc. are attached to the distribution center. Sent. Display device using CRT 27
Then, the operation of the control device 21 is observed one by one, and various lists such as processing results, reports, etc. are printed out from the printer 26.

The handy terminal 28 is provided with a display, a memory, a ten-key pad, etc., and when the terminal is connected to the control device after creating various actual inventory data for the items whose inventory quantities do not match at the work site, the control device Downloads data and stores it in memory.

Next, the operation of the picking system of the present invention will be described. The memory of the control device 21 stores the type and quantity of the articles arranged for each shelf number of each fluidized shelf based on the order data and the shipping record. When checking the stock quantity, repeater 24 reads the data from the memory, sends a signal to the relevant sections of the shelf controller 20 ₁ to 20 _n, a digital display of the number of articles contained in each storage bin Display in order on the container 17. The operator pushes the take-out completion switch when the actual quantity of the article matches the displayed quantity. Upon receiving this end signal, the control device sends the inventory quantity of the next article to the shelf controller and causes the digital display 17 to display the inventory quantity of the article. In the same way, the inventory quantity is displayed sequentially and checked.

If the displayed quantity is different from the actual quantity, the operator enters the data such as the corresponding bin number, article code, and actual quantity into the handy terminal, and the stock check of all the floating shelves is completed. From the above, the data is stored in the control device by correcting the data stored in the control device by connecting the cord to the control device 21. It is also possible to correct the data online by using the numeric keypad attached to the label issuing machine 23.

Although the gist of the present invention has been described above with respect to the specified embodiment, various changes and modifications can be made to the present invention based on what has already been described. For example, on the front of the shelf of each article, an article take-out number indicator and an take-out completion switch are provided for each article, and in inventory management of the articles,
Display the inventory quantity of the article on each display, and if the operator confirms that the displayed inventory quantity is the same as the actual inventory quantity, press the take-out completion switch to check that the inventory quantity of the article is incorrect. Various modes can be adopted, such as notifying the control device of the absence.

(Effects of the Invention) As described above, according to the present invention, the inventory quantity of each article is displayed by using the article take-out quantity indicator used during picking, and the displayed contents and the actual inventory quantity are displayed. If they are the same, the take-out end switch notifies the means for managing the stock quantity, so that the complicated stock quantity check can be easily performed in a short time.
