DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage rack and a transport control device for transporting stored items to the storage rack, and more particularly to a storage rack and a transport control device for storing rolls having various lengths.

[0002]

2. Description of the Related Art Conventionally, as a storage rack, there have been racks in which vertical (height), horizontal (frontage), and constant depth racks are arranged in a plurality of rows and columns, and both sides are fixed by columns. Also,
There are also storage racks that can change the vertical, horizontal, and depth, but in that case, it is possible to widen the frontage with partitions, and in the height direction, there is a method to stop the shelf board at 4 points on both sides with stoppers. As for the depth, two shelves were prepared and shifted in the depth direction to give flexibility.

Further, as the transfer device, there is a movable transfer device for transferring stored items to the storage rack by a movable transfer device,
There is known a stationary transfer device or the like having a rail arranged on the front surface of a storage rack and having a motor for rotating the vertical rotation rail along the rail.

Here, a conventional example will be described with reference to FIGS. In FIG. 8, it is assumed that the storage item 21 placed in the lower left stage is placed on the pallet 22 and stored in the storage rack 40. The storage racks 40 are fixed to both sides of the rail 25, and the movable transfer device 41 can move left and right on the rail 25. In the movable transfer device 41, a column 29 that also serves as a vertically movable rail is passed up to the top shelf 32 of the storage rack 40, and a control circuit for controlling various moving devices of the movable transfer device 41 is inserted in the transfer control device 30. The rotation of the vertically movable motor 31 causes the carrier 28 to rotate.
Moves. A rail motor 29 is used in the movable transfer device 41 so that the rail 25 can be moved, and a stopper 26 is fixed to the end of the rail 25.
Further, the stored item 21 to be carried out from the storage rack 40 is placed on the stored item table 23, and is carried out by the transfer device. The storage racks are fixed by vertical columns 24 for each rack, the height is common to each rack, and the depth is constant.

The loading and unloading of stored items in each rack of the storage rack 40 will be described. In FIG. 9, the carrier 28 has a loading / unloading motor 32 and a motor 32.
Rotation of the gear 33, for example, the recessed groove 34 is provided for each width of the gear fixed to the carry-in / carry-out substrate 31 in association with the gear 33,
It is movable in the front and depth directions. The carry-in / carry-out substrate 31 is inserted into the space portion 35 of the pallet shown in FIG. 10 to carry in / carry out the stored items placed on the pallet 32. In addition, the carrier 28 is formed by a roller 30 attached to a roller shaft fixed to the carrier in a column 29 of the movable transfer device 41, and by a rotating rail in the column 29 that meshes with the roller 30 by rotation of a motor 30 provided at the upper end. It can be moved up and down.

[0006]

In the above-mentioned conventional and general storage racks, when the stored items are automatically loaded and unloaded, the size of the loaded items is limited, and the size is smaller than the frontage, height, and depth. I hate that it is limited to items and lacks flexibility in the form of stored items. Especially when the roll diameter is constant but the roll height changes multiple times more than the minimum height, such as a roll of film or paper, control the storage by giving up the storage or placing it outside the storage rack. There was a problem in terms of storage and storage, and in the end there was a dislike of deteriorating the quality of the roll itself.

Further, although roll diameters are usually constant and rolls have different heights, if a transport control device can determine which of the storage racks can store the roll film and transport the roll film to the relevant rack. , A step closer to automated warehouses, and a useful system for increasing the reliability of management and maintaining quality is possible.

An example in which the roll film is stored in an upright position will be described. However, if the roll film is stored sideways, the roll film is deformed by its own weight to a high degree, which causes quality deterioration. It was decided to keep it.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned drawbacks, the present invention proposes a storage system in which storage rack units are arranged vertically and horizontally and fixed in a plurality of rows and each stage is set on the basis of the height of a minimum storage object. It is a rack, and a rack shelf support is provided for each height of the minimum storage items, and a freely rotatable shelf plate is attached to the rack shelf support to mount the storage items, and the storage items are not placed. The shelf is placed on the side or the back of the row side, and when the height of the stored items is N times the storage rack unit (N is a positive integer), the storage rack unit. (N-1) of the shelf board is mounted on the column side, and one shelf board is placed on the rack shelf receiver. In this storage rack, the shelf used as the bottom plate of each rack unit is normally placed upright, and the rack receivers of the storage rack unit are arranged around the unit, and the internal volume is very small, so the height is high. It does not get in the way of high roll film,
Multiple rack unit stages can be stored in a row, and there is also a rack unit with a shelf plate laid down under the stored items, so the storage racks in the warehouse can be used efficiently and help maintain quality.

Further, the present invention is a transport control device for transporting a stored item to a storage rack in which a plurality of rack units set based on the minimum height of the stored item are arranged in a plurality of rows and a plurality of stages. In the rack unit, the shelf is upright when the stored items are not stored, and when the stored units are stored, the shelf is placed on the rack shelf receiver to store the stored items. At this time, the height of the stored items is input, and the value of N corresponding to the height of (N-1) times the height of the rack unit (N is a positive integer) or more is calculated within N times. And asked,
The lowest shelf of the vertical rack unit stages corresponding to the N pieces is placed on the rack shelf receiver, and the shelf plate of the (N-1) stage rack unit is set upright to store the stored items. It is characterized by being stored in. This transfer control device puts down the rack plate of the required rack unit and puts it on the shelf receiver. When the amount of roll film stored is high, one of the unit rack groups knocks down the shelf plate, and the other stands. Since there are up to a few operations, the operation itself is less and the operation of the transfer control device is less wasteful, improving the storage efficiency of the storage rack and maintaining the quality of stored items,
It is also possible to easily manage the storage rack.

Normally, the permanent magnets 4 fixed to the back surface of the shelf board 2 are attracted to the columns 6, so that the storage items cannot be placed on this unit. . When a storage item is placed on this unit, the transfer device moves to the front of this storage rack row, moves the vertically movable carrier 13 to the height of the unit, and rotates the pulse motor 19. , If the handle 3 is used, press it with -10 to place the shelf board 2 on the shelf support 1,
After that, the roll film 7 is pushed out by the push-out arm 12, placed on the shelf board 2, and the roll-holding arm 11 is expanded and retracted. In this way, the roll film 7 can be stored. Next, when carrying out the stored items, the transfer device moves to the row of the storage rack, and the vertically movable carriers 13 are moved.
Is moved to the height of the shelf containing the stored items, and is sandwiched between the roll-holding arms 11 to be carried out and conveyed. At that time, the shelf plate 2 of the unit spreads to an angle of 90 degrees by the biasing force of the hinge 5, and is fixed to the support by the magnet 4.

Next, the operation of the control panel of this carrying device will be described.

First, the determination of the stages and rows of the present transport device will be described. In FIG. 4, reference numeral 55 denotes a crane of the transfer apparatus, which includes a proximity switch sensor 45 that detects a row of the storage racks 17 and a storage rack 1 when moving on the rails 18.
Proximity switch sensor 44 for detecting 7 steps is provided at a predetermined position. The storage rack 17 is provided with position indicators, such as photodiodes 42 and 43, at the positions sensed by the proximity switch sensors 44 and 45 of the crane 55 each time each stage of each rack unit passes and each time each row passes. , Keep it on all the time, or use sensors 44, 45
Illuminates before passing. Further, the position pointing device and its sensing means are provided with a protrusion at, for example, the lower left corner of each rack unit, and by moving the crane 55, the sensing sensors 44, 4

The memory 50 may be a memory in the chip of the CPU 49, a hard memory, or a floppy medium.

Here, as a premise for carrying in and carrying out the roll film 7, each shelf support 1 based on the shortest roll film height is fixed to the column 6 in a plurality of stages. The length of the shortest roll, which is the height of the shelf of this storage rack, can be variously determined depending on the type of items stored in this automatic warehouse or storage rack, and may be in accordance with the dimensions defined by JIS standards or the like. Not do. Further, at the vertical step position of the storage rack, the photodiode 42 is turned on as a proximity switch light emitting portion on each rack receiver of the rack, and the proximity switch sensor 44 provided in a part of the vertically movable carrier 13 of the crane 55 causes the step. The position of can be detected. Similarly for the horizontal row position, the photodiode 43 is turned on for each row of rack shelves in the rail 18 direction of the crane 55, and the position of that row can be detected by the proximity switch sensor 45 as the crane 55 moves. Receiving these positions from the row counters 46 and 47, the CPU 49 virtually manages the address table in the memory 50 with the bottom of the last row of the storage rack as the starting point of the address.

Hereinafter, the operation of the transfer device having the above-described structure will be described with reference to FIG.
This will be described with reference to the flowchart of FIG. First, in FIG. 6, the loading operation of the roll film 7 is started (S1). When the roll film 7 is loaded into the automatic warehouse, the product name of the roll film 7 is input, and the CPU 49
Extracts the height from the data of the product name, from the data of the memory 50 (S2). Alternatively, the height data of the roll film 7 can be input and known, and the input means is not particularly limited. The number of times the height of the roll film 7 corresponds to the minimum unit of the rack unit is calculated (S3). Here, it is assumed that it is P times. When P includes a small number, it is rounded up to a positive integer N. Therefore,
The height of the roll film 7 is equal to the height of the rack unit (N
It is between -1) times and N times.

The CPU 49 searches the address table of the memory 50, detects a vacant place of N stages in the vertical direction,
An empty space address in which the roll film 7 can be entered is specified (S4). At least "present" and "absent" marks are attached to the memory-mapped address table built in the memory 50. Also prepare an inventory table,
In the inventory table, the item name, the height of the item name, the number of items in stock, the stored address, etc. are recorded and used for management. Next, the difference from the empty address is obtained from the starting point of the transfer device, and the crane 55 of the transfer device is moved to the target row along the rail 18 (S5). Further, the vertically movable carrier 13 of the crane 18 is moved to the target stage (S6). In these movements, the proximity switch sensors 44 and 45 sense each time the light emitting means 42 and 43 pass, and the counters 46 and 4 are detected.
Since 7 counts up, the CPU 49 can read the count value and carry the carrier to the target row or target stage.

Next, when the vertically movable carrier 13 arrives at the storage rack unit corresponding to the designated address, the movable shelf differential lever 10 is operated by the motor 19 so that the roll film 7 can be placed. The handle 3 is rotated so as to be pushed out, the shelf plate 2 which is erected by the magnet 4 is placed on the shelf support 1 (S7), and the roll film 7 is pushed out by the pushing arm 12 into a rack unit corresponding to N stages. The roll holding arm 11 is pushed out onto the lowest shelf plate 2 and is stored (S8). After that, the crane 55 moves the vertically movable carrier 13 to the lowermost stage, moves the rail 18, and returns to the starting point (S9). Then, the operation at the time of loading is completed (S10). Although the example in which the main crane 55 starts from the starting point and returns to the starting point is shown, the crane 55 may end as it is when stored in the storage rack unit. In this case, the CPU 49 manages where the vertically movable carrier 13 is located on the address table, and when the carry-in command is issued and the carry-in address is determined, the CPU 49 returns from the current address to the starting point and rolls the roll film. 7 is sandwiched and placed on the vertically movable carrier 13, and control is performed to move it to a target address.

Next, the case of carrying out will be described with reference to FIG. When a request to carry out the roll film 7 is issued (S11), for example, the product name of the roll film is input (S12), and the CPU 49 detects from the stock table in the memory 50 whether or not the corresponding roll film 7 exists. (S13). If there is no stock, go back to the start. Next, the address at which this roll film is in stock is detected and extracted (S14). Based on the difference between the target address and the current address position of the crane 55, the crane 55 is moved to the target row (S15) and the vertically movable carrier 13 is moved to the target stage (S16). Next, the roll film 7 stored in the rack unit is held by operating the roll holding arm of the crane 55, taken out from the rack unit, and placed on the vertically movable carrier of the crane 55 (S17). At that time, the shelf board 2 placed on the shelf support 1 of the rack unit automatically returns to the side surface of the rack unit due to the repulsive force of the hinge 5.
The permanent magnet 4 is applied to the column. Then the crane 55
Is returned to the starting point (S18), and the pushing arm 12
The roll film 7 to be pushed out and carried out is placed on the base. At that time, the CPU 49 clears the address table in the memory 50, and changes / deletes necessary parts from the inventory table. In this way, the carry-out operation is completed (S1
9).

In the above embodiment, an example in which the shelf board of the lowest rack unit of a plurality of rack units is placed on the shelf receiver from the address table has been described.
When the roll film to be stored is less than N times the height of one rack unit, the lowermost rack unit for placing the shelf on the shelf receiver and the upper (N-1) th shelf are set up. By maintaining the state, it is possible to store less than N times as many storage items.

Further, in the crane of the above-mentioned embodiment, as a method of moving the vertically movable carrier up and down, there is another method of rotating the chain by a step motor using a chain, and by a rope by a motor as in a normal elevator. However, the present invention is not limited to these.

Also, in the method of placing the shelf plate on the shelf receiver, in addition to the above-mentioned embodiment, for example, it is normally held in an upright state by magnetic force, and a force acts on the hinge in the direction of closing with a spring. After removing the stored items, grasp the handle or shelf plate with the electromagnet provided at the tip of the arm provided on the crane or lift it with magnetic force, and then to the column or the side plate or the back column or It is also possible to use a method of holding the sheet metal with the magnetic force of the shelf plate.

Further, although the storage racks are arranged on both sides of the rail on which the crane is mounted in the above-mentioned embodiment, they may be one rail or a circulating rail. The inventory table is not limited to the mechanical structure as long as the inventory management and the address table utilization / management are performed as described above.

[0026]

As described above, according to the present invention,
Even stored items having various roll heights can be automatically stored in a rack unit group having a predetermined height when transported to an automatic warehouse. Further, since the shelf film is placed on the lowest shelf shelf of the rack unit group having a predetermined height to store the roll film, the automation is simple and the complication during transportation can be minimized.
