JPH03272901A - Discharge request method for automatic multiple level warehouse - Google Patents

Abstract

PURPOSE:To reduce the burden of discharging work by inputting the coded name of a commodity to be unstocked so that requested parts and discharge reserving patterns are displayed and request signals are input from a discharge request device to a central control device in accordance with such a display. CONSTITUTION:When discharging workers input the coded name of a commodity to be discharged to a keyboard 9a, a discharge control device 9 transmits the coded name of the commodity to a central control device 6. The central control device 6 searches whether the commodity is in stock or not and tells the discharge control device 9 if in stock. The discharge control device 9 displays transferred data on a CRT 9a. Through this display, a discharge request button for discharge request devices 8a, 8b... is depressed. The result is sent from the discharge control device 9 to the central control device 6, which drives a stacker crane ground control device 7. In this way, the burden of discharging work can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an operating method for processing a shipping request in an automated multi-story warehouse.

Conventional Technology] Due to the recent needs for FA and CIM at manufacturing sites, there has been an increase in the number of cases in which automated multi-level warehouses are installed between processes for the purpose of distributing parts to subsequent processes. This type of automated multi-storey warehouse is provided with a plurality of entrances or exits in order to efficiently carry out warehousing and unloading operations.

Generally, the following method is adopted when providing multiple exit ports.

1) Depending on the layout of equipment for post-processing, a plurality of exit ports are provided at intervals at the bottom of the multi-story warehouse.

2) Install multiple exits in parallel at the bottom of the multi-storey warehouse.

When the products needed in the next process are to be delivered to these exits, the method described in item 1) above will either automatically take them out based on instructions from the host computer system, or the delivery worker will issue them to the delivery control device. By inputting the name of the part to be delivered, etc., it is possible to carry out the delivery process without placing too much burden on the worker.

On the other hand, in the method of Type 2), when parts with the same name are to be delivered to a plurality of parallel delivery ports, it is possible to dispatch the parts based on a command from the -1 place computer. However, if there is a request from the next process, for example, a request for parts with two types of plates, it is necessary to select which product name to go to which warehouse out of the parallel warehouses. We have four delivery workers tasked with making delivery reservations. In this method, due to the recent trend toward high-mix, low-volume production, the number of reservations for delivery may reach 20 to 30 times per shift.

[Problem to be solved by the invention] = As shown in the following, an automated multi-level warehouse where multiple exit ports are installed in parallel and 22 or more types of parts are delivered in succession. However, there was a problem in that it placed a heavy burden on the shipping workers.

It is an object of the present invention to provide a method for requesting warehouse delivery in an automated multi-story warehouse that does not impose a burden on the warehouse delivery work and also eliminates the need for transport equipment near the day of delivery.

[Means for Solving the Problems] The present invention provides central control in advance of an outgoing reservation pattern of which shelf of the outgoing warehouse L1 is to be outsourced for each product name in an automated multi-story warehouse in which a large number of outgoing warehouses L1 are arranged side by side. It is registered in the device, and when a shipping request is made, the name of the product requested for shipping and the shipping reservation pattern for the product name is displayed on the display device of the shipping saving device, and the shipping request is sent from the shipping request device installed at each warehouse. The method for requesting delivery of an automated multi-story warehouse is characterized in that when a signal is manually input to the delivery control device, the delivery control device transmits delivery request data to a central control device.

[Examples] The present invention will be described below based on Examples. FIG. 1 shows a configuration diagram for carrying out the present invention, in which 1.2 is a row of shelves in an automated multi-storey warehouse, and 3 is a stacker crane. In the example shown in FIG. 1, the top shelf of the shelf row 1 is a dedicated machine for warehousing (hereinafter referred to as warehousing ports 1a, lb, lc, . . . ). At these warehousing entrances, warehousing request panels 4a, 4b, 4c, . . . are installed.

On the warehousing request boards 4a, 4b, 4c, . . ., a worker registers the warehousing request by setting the part number, quantity, etc. of the part for which the warehousing request is made. A push button is provided.

Reference numeral 5 denotes a warehousing control device consisting of a microphone (L12), a monitor (12), and a CR, T, and keyboard (not shown) are connected thereto.

Warehousing D 1 a, 1 b, 1. c, ,,,
Although not shown in the figure, there are a number of pre-processing machines or a number of warehousing conveyors installed next to the machine.

Further, in front of the exits A, B, C, . . . , H, assembly machines and the like for the next process are installed.

FIG. 2 shows an example of the data of the stumbling block pattern that is registered in advance in the storage device of the central control device 6. The retrieval reservation pattern refers to which parts to be delivered to which DA and B when making a retrieval request.

It is possible to set in advance which shelf C1..., H is to be delivered, and for all part codes, the delivery [1 by 4z Q
Or memorize l. For example, a value of 1 indicates that a reservation has been made for leaving the warehouse at the corresponding exit, and a value of 0 indicates that no reservation has been made for leaving the warehouse. This retrieval reservation pattern is registered in advance in the storage device of the central control device 6 for all parts codes to be reloaded and retracted.

Next, the operation of the present invention will be explained. When making a warehouse delivery request, the warehouse worker inputs the product name code to be delivered from the keyboard 9a. Then, the shipping control device 9 transmits the input product name code data to the central control device 6. The central control device 6 searches for whether or not this product name code is in stock (for each part code), and if it is in stock, transmits the data on the number of items in stock and the delivery reservation pattern to the delivery control device 9. The delivery control device 9 displays the above-mentioned transmitted data on the CRT 9a as shown in FIG.

The shipping worker can see the CRT screen shown in FIG. 3 and know which product name the parts are reserved for which shipping exit. In addition, each delivery request device 8a, 8b, . . .
It is also possible to display which part code is reserved for delivery.

Next, the shipping worker uses the shipping requesting devices 8a, 8b8c, etc.
・Press the delivery request push button located at . Then, a delivery request signal is input to the delivery control device 9. The delivery control device 9 transmits delivery request data (delivery exit shelf address, product name code, part code, etc.) to the central control device 6. The central controller 6 issues an operating schedule for the stacker crane 3 and transmits this data to the stacker crane ground controller 7 . The stacker crane ground control device 7 converts this operation schedule data into travel distance data and transmits an operation command to the stacker crane 3.

The operation of the stacker crane 3 is as follows: First, it transports the empty pallet at the exit for which the delivery request has been made to the empty space, then it takes out the pallet storing the product name (parts) for which the delivery request was made to the exit. Ends one cycle of operation schedule.

In the present invention, it is also possible to add a function to modify the exit reservation pattern using the keyboard 9b using the CRT screen shown in FIG.

(Effects of the Invention) The present invention described above has the effect of significantly reducing the burden of the warehouse retrieval reservation work on the warehouse worker in an automated multi-story warehouse in which a large number of warehouse exits are arranged side by side.

This is especially effective when two or more types of parts are delivered consecutively.
