[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic warehouse which accommodates a plurality of reels around which a tape having electronic parts is mounted and which automatically takes out any one of the reels.
In particular, it relates to an automatic warehouse that automatically supplies reels to an automatic insertion machine.

[0002]

2. Description of the Related Art As a method of storing the above reels and taking out the necessary reels, a manual type and an automatic warehouse type are currently in the mainstream. In the manual method, reels are stored in flat shelves for each type, and a worker walks around each shelves based on a shipping instruction list, takes out the necessary reels, and combines them. Further, in the conventional automatic warehouse system, the buckets containing the reels are placed on the rotary table or the lifting table, and the operator automatically moves the table to take out the buckets containing the required reels one by one. The worker takes out the required number of reels from the bucket.

[0003]

However, the above-mentioned manual method has a problem that when the number of types of reels increases, a lot of manpower is required to search for a required reel or to check the number of reels. It was In addition, there was a high possibility that errors would occur due to manual work.

On the other hand, according to the conventional automatic warehouse, it is possible to save the trouble of searching for a bucket, but since the worker manually takes out the reels from the bucket, it takes time for the goods to be unloaded.
There was little labor saving effect.

The present invention has been made in view of such a situation, and can automatically take out the required reels automatically, increase the delivery capacity and save labor, and prevent the occurrence of mistakes. The purpose is to provide.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the automatic warehouse of the present invention will be described below with reference to the drawings.

1 to 6 show the structure of an embodiment of the present invention. In FIG. 1, on a base 1, a plurality of storage compartments 3 that constitute the main body of the automated warehouse 2 and are partitioned in the vertical direction are arranged in parallel. Also, on the base 1 on the front of the storage case 3,
A lower conveyor 4 that moves along the storage 3 is provided, and the lower conveyor 4 is turned at a right angle at a position where the lower conveyor 4 is separated from the end of the storage 3, and a pickup station 6 having a pickup mechanism 5 is provided. It has been extended to the position. Further, the lower conveyor 4 is connected to an upper conveyor 7 provided on the upper rear surface of the storage 3.

Each storage case 3 is provided with a drawer mechanism 11 shown in FIGS. The storage 3 is composed of four square pieces 12, and a square-shaped tray 14 in which a plurality of reels 13 of the same kind are stored in parallel is stacked between the square pieces 12. Two pairs of upper and lower rollers 15 are rotatably supported between the square members 12 in a direction perpendicular to the lower conveyor 4, and a pair of endless belts 16 are vertically stretched between the rollers 15. There is. The belt 16 holds the tray 14 from both sides, and the drive source (not shown) rotationally drives the roller 15 to hold and lower the tray 16.

As shown in FIG. 3, a cylinder 17 whose axial direction is vertical is provided in the lower part of the storage case 3, and a table 19 is attached to the upper end of a rod 18 of the cylinder 17. Then, the tray 16 lowered by the belt 16 is placed on the table 19, and the table 19 is lowered by the cylinder 17 so as to have the same height as the surface of the lower conveyor 4. Further, at the lower end of the storage case 3, FIG.
As shown in FIG. 3, a payout opening 20 for pulling out the tray 16 onto the lower conveyor 4 is provided.

Further, as shown in FIG. 2, a pusher 2 which is horizontally moved by a drive source (not shown) is provided in a lower portion of the storage case 3.
1 is provided. The pusher 21 is a tray 1 positioned on the table 19 at the same height as the lower conveyor 4.
It has a function of pressing 6 to move it onto the lower conveyor 4.

On the other hand, the take-out mechanism 5 is a robot 31 shown in FIG.
And a pusher 32 shown in FIG. The tray 14 is formed in a rectangular shape as shown in FIG. 6, and a plurality of partition plates 33 are provided inside in parallel in the vertical direction. Further, a square hole 14a is formed on the bottom surface of the tray 14. Further, a pusher 32 is vertically provided in the base 1 of the pickup station 6, and the tray 14 transferred to the pickup station 6 is provided.
The reels 13 are projected upward one by one by the pushers 32 through the square holes 14a on the bottom surface of the. Then, the ejected reel 13 is taken out by the robot 31 and placed on the carrier 34.

FIG. 7 is a block diagram showing the control mechanism in this embodiment. The CPU 41 has a bar code reader 42
The barcode of the assembly part read by is input,
The operating program is set. Instructions corresponding to this program are sent from the CPU 41 to the sequencers 43 and 4, respectively.
It is sent to the drive source of the pull-out mechanism 11, the take-out mechanism 5 and the conveyors 4 and 7 via 4, 45 to control the respective operations.

Next, the operation of this embodiment will be described. As shown in FIG. 8, it is assumed that the storage case 3 is composed of six rows A to F, and that the trays 14 on which different types of component reels 13 are placed are stored in the storage cases. From the CPU 41 to the pull-out mechanism 11, as shown in FIG. 9, B, D, A, C,
When a storage request is issued in the order of F and E, first, the respective drawer mechanisms 11 are operated to simultaneously draw out the trays 14 of B and D onto the lower conveyor 4. When the trays 14 of B and D are conveyed by the lower conveyor 4 and have passed through the storage A, the trays 14 of A, C and F are similarly pulled out at the same time. When the trays 14 of A, C, and F have passed the storage A, the tray 14 of E is similarly pulled out.

The trays 14 that have been pulled out are sequentially conveyed to the pickup station 6, and the pickup mechanism 5 operates in the pickup station 6 in response to a command from the CPU 41. Then, a predetermined number of reels 13 placed on each tray 14 are sequentially projected by the pusher 32, and the reels 13 are sequentially taken out by the robot 31 and placed on the carrier 34. The tray 14 from which the required number of reels 13 have been taken out is conveyed by the upper conveyor 7 to the upper rear surface of the storage case 3 and is stored in the storage case 3 of a corresponding type by an automatic sorting device (not shown).

According to this embodiment, the required trays 14 are sequentially conveyed to the pickup station 6 in response to a command from the CPU 41, and the required number of reels 1 are taken out by the take-out mechanism 5.
Since 3 is automatically taken out, it is possible to prevent the occurrence of a shipping error and achieve labor saving. Further, a greater labor saving effect can be obtained as compared with the conventional automatic warehouse of the rotary lifting type, and the unloading capacity can be improved.

The number of storages 7 and the storage order shown in the above embodiment are examples and are not limited to these.

[0025]

As described above, according to the automatic warehouse of the present invention, the controller drives the pulling mechanism to sequentially pull out the required trays, the conveyor conveys the trays to the takeout mechanism, and the takeout mechanism needs the trays. Since a large number of reels are automatically taken out one after another, it is possible to prevent a delivery error and save labor.
