JPS6216930A - Wire-rod coil depository control method in flat warehouse - Google Patents

Abstract

PURPOSE:To aim at reduction in the number of warehousemen, by detecting a crane traveling position automatically, while displaying an operation command with a terminal machine and judging it automatically with three-dimensional coordinates through a computer for determination. CONSTITUTION:A computer 1 depicts depository information as every column and stage from an external memory 2 and displays a baling image on a picture while discriminating fullness, space in reserve, room, and the presence of shipping and receiving booking. With this image on the screen, a warehouseman finds an optimum space, while a computer 1 secures as a receiving reservation depository in order of a required space on the basis of the inputted layer- stacking restrictive condition, and stores the reservation and schedule order. At the time of product arrival, information of a crane unit is made out, while on the basis of the storage order made out, a receiving command display is given to a crane mounted station 4. When a crane man makes his crane travel toward a column of the display position, a position detector in the traveling direction operates, making sure of a congruity with the displays between the command column and the existing column, thus operation-end is inputted.

Description

[Detailed description of the invention] &#MJ M5i of invention! Description (Industrial Application Field) The present invention is a method for three-dimensionally converting products that can be considered to be the same, such as wire rod coils, by using, for example, a loading and unloading means in which loading and unloading of articles is limited to a certain direction. This relates to a storage management method for a flat warehouse where cargo is stored.

(Prior art) In a flat warehouse for the above-mentioned products, such as wire rod coils,
From the viewpoint of storage efficiency, it is common to stack them in bales.
Conventional storage management systems rely on manually created forms as living information. In recent years, storage yard management using computer processing systems has been carried out, but this management is
Divide the warehouse into several blocks, and in each block, there is a coil of m material at this location, or a device of this wire coil t. Condition (the image of bale stacking has not yet been grasped).

(Problem A to be solved by the invention) (1) J: In the conventional f-lift management mentioned above, the following

Search for the actual item when pulling the product Cl1ll Signal for loading and unloading the product to the crane operator (2-
To understand the condition of bale bales mentioned above, mark the storage area in three dimensions.
B! It is easy to think that this three-dimensional coordinate management can be done by equipping the clay with position detectors in the travel, traverse and height directions.
There is a problem in that this requires a large investment cost.

(Means for solving the problem) A method of managing three-dimensional coordinates of the unexploded BAfi storage site at a low investment cost with the aim of improving the amount of buried waste and reducing the number of storage personnel. This is what we provide.

And 1 dud E! A is a terminal device that has a position detector that automatically detects the clay/travel position attached to the crane, a means for displaying work instructions, and a means for setting and inputting work photons, and automatically detects the crane in the height and depth directions using three-dimensional coordinates. Judging by
A wire rod coil in a flat warehouse characterized by managing the three-dimensional coordinates of a bale-pounding wire rod coil storage area using a computer/computer having a function of determining the wire rod, and transmitting information between the crane operator and the computer in real time. This is a storage management method.

(Function) As shown in FIG. 1, the devices necessary for carrying out the method of the present invention include a computer 1, an external storage device R2, and a transmission line connected to the computer 1 and external storage device R2. A crane equipped with a crane ground station 3 that performs transmission control, etc., a position detector that detects the position based on the travel distance of the crane, and a terminal equipped with display and input functions for transmitting information between the clay/man and the computer.

This is a processing function that is attached to a computer in order to update data stored in the computer.

In addition, in the method of the present invention, the contact material coil is baled as shown in Fig. 2, and since the outside of the wire coil is constant, 1.
Once the column number is determined, the number of stages to be stacked is that odd numbered rows have only odd numbered stages, and even numbered rows have only even numbered stages.Since it is an IC, it is necessary to be able to draw a two-dimensional cross-sectional view, and to make it three-dimensional by adding English rows, the length of the coil must be determined. It is possible to do this by knowing that, and in the 07-tsuku, when putting things in and taking things out of the same row and the same level, it is impossible to do anything other than starting from the back and taking things out from the front. This is a management method that utilizes these t# characteristics.

The operation of carrying out the management method of the present invention using the apparatus t shown in FIG. 1 will be explained with reference to FIGS. 3 to 8.

First, the computer's external storage device ft2U, column.

It has data that defines the number of coils for each stage, and has the function of determining whether the stage is full or not. With this function, for example, when using a wire coil t device, taking the 4th stage fEJ in Figure 5 as an example, you can find out where the 1st was located in the 4th stage of the 06th row in the forward direction, and the corresponding row 7 You can understand what the occupancy rate of the stage is. Also, when taking out the # material coil, how about taking the 4th stage in Figure 8 as an example? a06
Where in the depth direction of the 4th row should you pick the object? You can see if you rolled a 7. In accordance with these loading or unloading operations, data in the computer external storage device 2 is updated to display work instructions and schedules.

These actions will be explained in detail below, divided into warehousing work and warehousing work.

(1) Stocking work The processing in the warehousing work is performed according to the following steps.

Medium Storage space reservation processing for storing incoming products (It)
Instruction light display process to the crane operator when the product arrives 01# Work completion process for the crane lifting unit OV) Warehousing work completion process (Based on the production schedule of 1, as shown in Figure 3, The thickness of the management is that if the buried person requests that the image of the stacking of sheets in the yard (mountain image) be displayed on the C-box T5, the computer will be displayed.
extracts the f-field information for every two rows from the external storage device ft2, and displays a mountain image on the screen while identifying whether it is full, with extra space, empty, and whether there is a reservation for shipping or receiving. **The operation manager can use this screen to find the optimal space, start position with production lot NLL%, and planting pattern.

Enter stacking constraints. Based on this condition, the computer knows the manufacturing rate @ hotoku amount.

For example, as shown in Figure 4, secure a safe space for loading as a reception reservation and place in the order of ■ - C ■.

Memorize the planned planting order.

(The effect of 1υ is warehouse operation 'W burial μ. When the product arrives, information on the crane hanging unit is created according to the size of the product. At the same time, based on the planting order created in 1 At step 4, an acceptance instruction is displayed.

The crane onboard station 4 has two screens, one of which numerically displays the number of remaining lots to be accepted, the stacking order of each row/tier, and the row/level to be unloaded this time.

On other screens, an image of a mountain near the &phrase-is location is displayed along with identification of the reserved location, existing stock, etc.

When the crane operator moves the crane toward the displayed row that should be lowered this time, the position detector in the traveling direction is activated, and when the crane reaches the range of the specified row, a chime will sound, for example.
IJ″t″ru. Stop the crane, confirm that the row to be lowered next time matches the display of the current row, and input the work completion.

Based on this, the computer determines the stage, the existing inventory, the address for the direction from the bottom to the bottom, and the occupied iIt, and updates the data stored in the computer. Furthermore, the same
If there is any remaining in the production lot, determine the next instruction, update the ml,
), but when the running direction position detector detects column No. 06, there are only even-numbered columns in this column.

First, in step 2 (b), check whether the product can be placed in the storage area. If it is determined that the area is full and cannot be loaded,
(Determine whether nJ, that is, it can be placed in 6 rows and 4 stages.<
n) is not full, and <1) * (m+
), it is determined that the pieces l1Jr are placed in 6 rows and 4 tiers if both of them have enough downward horizontal movement to lower the current hanging amount. In the direction to the husband, the address is determined and the occupancy rate of 6 rows and 4 rows is calculated assuming that the current hanging amount is placed on the front side of the existing stock of 6 rows and 4 rows.

With the action of 4v and the action of 0yu, if the load just unloaded is the I & later load of the manufacturing lot, and there is space for wood at the reservation field,
It works to release this. Also, if the next production loft has arrived (return to ID action).

(2) Shipping work The thickness work is done in the following steps.

(1) Reservation processing for products to be shipped (11) Process for displaying instructions to the crane operator at the start of loading work 016 Work completion input for crane lifting unit (1) Based on the shipping schedule or upon arrival of the transport aircraft.

As shown in FIG. 6, the warehouse operations manager A inputs a request to the CBr4 to display an image of a mountain near the storage area where the shipping lot is located. In response to this request input, a mountain image of the incoming rhinoceros (υ) is displayed on the screen as in the case of the υ action.The warehouse operation manager inputs the payout start position and payout noseter on this screen.The computer uses an external storage device. The amount to be delivered is determined from the shipping instruction information in step 2, and the external record t changes the order of steps from ■ to ■ in Figure 7 to the crane's lifting system based on the IIIt field information stored in the device 2 and the long-term conditions. Decide and memorize the units that are appropriate for the unit.

(The effect of the ID) Upon receiving the notification from the transport aircraft 4 or the beach departure, the crane operator processes the instruction display from the onboard station 4 and displays it on the screen. is shown and displayed in payout amount.

When the crane operator moves the crane toward the displayed column to be hoisted this time, a position detector in the traveling direction is activated, and a chime, for example, sounds when the crane reaches the range of the specified column. Stop the crane, check that the row to be hoisted this time matches the display of the desk row, and input the work completion. Based on this, the computer determines the stage and hangs it this time! 7. Subtract an amount corresponding to the amount from the existing data and update the external storage data. Furthermore, instructions for lowering the suspended wire coil are displayed.

To explain the effect of payout address determination on an example in which a payout is to be made from (n) using the eighth factor, F train pigeon 06 is first detected by the position detector in the running direction.

When row 06 is detected, since there are only even-numbered stages in this row, first it is determined whether there is a wire coil in (Q, l, that is, in the 6th row and 6th stage. There is no product in (Q). If <n
) That is, it is determined whether there is a product in the 6th row and 4th stage. (, n
), there is a wire coil, and the wire coil has been instructed to be dispensed.

Furthermore, it is determined whether there is no product in (ON) or if the product is stacked only on the back side of the discharge valve.These conditions ta
If the sum is added, it is determined that it has been hung on clay, and the payout address is determined and the occupancy rate of 6 rows and 4 stages is calculated.

(Effect of the invention) (υ Based on the storage site file memory that is updated in real time by the computer) Since instructions are displayed to the crane operator at the specific pick-up position f', there is no need for lower-level staff.

CII) Since the status of the storage area is displayed in three dimensions on the U-T printer, it is easy to search for and secure an empty t storage area, and it is easier to find the crossbar of the actual item because it displays the i]+details of the location of the congratulatory gift. Because of this, it is possible to reduce the number of Kurasai Ungu management staff.

OiD Furthermore, since it is possible to issue shipping instructions preferentially starting from the top 10,000 in the pile, the frequency of pile-up is reduced.

(2) The position detector only needs to be installed in the direction of the crane's movement, and it is cheaper to use the position detector.
