Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic bolt supply device for automatically supplying a predetermined number of bolts to a control plate for bolt management.

[0002]

2. Description of the Related Art Conventionally, for example, in order to assemble a predetermined number of seats, various types of bolts corresponding to the number of seats are required.
These bolts are manually pre-aligned with a control plate for bolt management. By aligning various types of bolts on this management plate, when assembling the seat, it is possible to assemble the seat by accurately using various types of bolts for each seat,
Prevents quality damage due to missing bolts.

[0003]

By the way, when aligning the bolts on the management plate, many types of bolts are manually arranged and arranged on the management plate according to the number of seats produced, which requires a lot of man-hours. There was a problem that the number of bolts was wrong. Therefore, an object of the present invention is to enable the bolt to be accurately supplied to the management plate.

[0004]

In order to achieve the above object, an automatic bolt feeder according to the present invention places a large number of bolt management plates with bolt receiving holes on its upper surface and transfers it in the front-back direction. In the middle of the transfer process, the transfer process, the bolt inserted into the chute from the bolt feeder is set in the bolt storage hole of the bolt management plate. The chuck process is installed above the end of the transfer process and the bolt management plate is placed on the alignment table. It is characterized in that it comprises a control plate taking out step.

The above-mentioned transfer process, chucking process, and control plate extracting process are all controlled by a computer, a predetermined number of bolts are stored, and are automatically set on the bolt control plate.

The slide rail (31B) extends from above the rail (10) to above the alignment table (4).

The alignment table (4) supports a mounting plate (40) for mounting the bolt management plate (100) on a standing rod (41) standing parallel to the support column (42) so as to be vertically movable. A large number of bolt management plates (100) are mounted on the mounting plate (40). Then, the mounting plate (40) is controlled so that the uppermost bolt management plate always has a constant height, and the mounting plate (4) is controlled by the management plate extraction step (3).
The bolt management plate (100) is properly placed on 0).

The respective steps and mechanisms such as the transfer step (1), the chuck step (2), the control plate take-out step (3) are automatically controlled by a microcomputer.
It is configured to be automatically operated by operating a start switch (not shown).

In FIG. 2, various types of bolts (5A) (6A) (7A) are stored in the bolt management plate (102) by using this apparatus and stacked on the mounting plate (40) of the alignment table (4). Indicates the state to do.

First, the bolts (5
A) (6A) (7A) and the number of bolt management plates (100) ... are laminated on the movable plate (11). After that, when the planned production number of seats, etc. to be produced by using the bolts (5A) is input to the microcomputer, each bolt (5A) is automatically set to the supply plate (22) by electric control. The number of sent bolts is stored in the microcomputer, and when the start button is operated, the bolt control plate (100) stacked on the movable plate (11) ... 100) and the bolt management plate (101) above it ...
And are separated by the separation mechanism (8).

That is, the left and right insertion plates (80) (8
0) is the lowest bolt management plate (10) in FIG.
2) It is inserted by the horizontal cylinder (82) into the notch of the bolt management plate (103) located on the upper side, and is moved upward by the upper and lower cylinders (81A) (81B), so that the bolt management plate (103) and its The bolt management plates (104) stacked above are the insertion plates (80) (8) above the lowermost bolt management plate (102).
0) lifted.

Then, the lowermost bolt management plate (102)
Only the movable plate (11) is placed on the movable plate (11), and the motor moves it on the rail (10) downwardly by the chucking process (2) as shown by a chain line. Then, the chucking step (2) causes the supply plate (22) to move to the bolt management plate (10).
Each of the bolts (5A) (6A) (7A) is supplied to the storage hole (100A) at a predetermined position of 2) by storing the head upward as shown in FIG.

Each bolt (5) to the bolt management plate (102)
When the storage of A) ... Is completed, the motor moves the bolt management plate (102) to the end of the rail (10).
The left and right sides of the bolt management plate (102) are gripped by the gripping mechanism (30) in the management plate extraction step (3), and the alignment table (4) is placed by the slide mechanisms (31A) (31B) (31C). It is placed on the plate (40).

After that, the insertion plates (80) (80) of the separating mechanism (8) are lowered to move the bolt management plate (103) and the bolt management plates (104) laminated above it to the movable plate (80). 11) Insert plate (80) after mounting on
Each (80) moves outwards by the extension of the horizontal cylinder (82). This allows the insertion plate (80)
(80) disengages from the bolt management plate (103), and the upper and lower cylinders (81A) (81B) extend to move the insertion plates (80) (80) upward by the vertical thickness of the bolt management plate (103). Let Then, by contracting the horizontal cylinder (82), the left and right sides of the bolt management plate (104) are clamped and lifted upward, so that the bolt management plate (103) is located above the bolt management plate (104).
… Separate more.

Next, the bolt management plate (1
03), the bolts (5A) are housed and stacked on the mounting plate (40) of the alignment table (4). By sequentially repeating this, the bolts (5A) ... Which match the planned production quantity are supplied to the large number of bolt management plates (100). In addition,
Bolt management plate (100) accommodating each bolt (5A) ...
... are transported to the production line and used for assembly.

[0027]

According to the present invention, since the bolts are automatically set in the bolt management plate having the bolt storage holes according to the planned production quantity, the bolts can be manually set as in the conventional case. Compared with this, the workability of the set is good, and no set mistakes occur. Therefore, it is possible to reliably manage the bolt, prevent the quality of the product from being deteriorated due to the lack of the bolt, and reduce the man-hour for supplying the bolt.
