At the end of the rail 31, an upper blade 46 and a lower blade 47 for shearing the second part 2 that has been transferred by a certain amount are arranged, and in front of the upper blade 46 and a lower blade 47, which are not shown, the comb tooth part 4 of the second part 2 is cut into the first part. An insertion device for insertion into the hole 6 of 1 is installed.

"The action of invention" Next, the operation of the above embodiment will be explained.

First, the pitches C of the plurality of holes 6 formed in the first part 1 are equally spaced. In order to sequentially transfer this first part 1 by a certain amount, first, the carrier plate 10
is raised in the R direction, whereby the carrier plate 1
A claw member 11 fixed to the upper end of the first
It is placed in contact with the rear end surface of the component 1.

Next, the carrier plate 10 moves forward in the Q direction (component conveyance direction). Therefore, since the claw member 11 also moves in the Q direction, the first part 1 is moved forward by a certain amount. Thereafter, the carrier plate 10 descends in the R' direction, then retreats in the Q' direction and returns to its home position. As a result of these operations, the first part 1 is sequentially and intermittently transferred forward.

However, the claw member 1 fixed to the carrier plate 10
Regarding the interval 1, the number of holes 6 in the first component 1 is not necessarily limited. Therefore, the first part 1
The longitudinal dimension of is also not limited. Therefore, as shown in FIG. 3, the claw members 11 are fixed to the carrier plate 10 at equal intervals X with the maximum dimensions within a certain range.

Next, the transfer of the second part 2 will be explained. First, the small holes 5 and the comb tooth portions 4 formed in the band-shaped portion 3 of the second component 2 are formed with the same pitch as the pitch C of the holes 6 in the first component 1, and 6 are transferred at once.

Therefore, as described above, in order to transport the first part 1 to a fixed position by advancing the carrier plate 10 and simultaneously transport a certain amount of the second part 2 to the fixed position in the same direction, first, the carrier plate 10 must be moved forward. When the carrier plate 10 is raised in the R direction, the operating plate 45 fixed to the carrier plate 10 also rises. This operation plate 45
As the support member 36 rises, the support member 36 moves upward via the bearing 43. As a result, the pilot pin 38 fixed to the support member 36 is raised to a height that does not hinder the passage of the second component 2 through the rail 31.

Thereafter, by moving the carrier plate 10 forward in the Q direction, the first part 1 is transported to a fixed position, and at the same time, a fixed amount of the second part 2 is transported to the fixed position in the same direction (Q direction). At this time, the operating plate 45 remains elevated and moves horizontally while contacting the bearing 43 of the support member 36. On the other hand, the push plate 23 fixed to the carrier plate 10 moves forward as the carrier plate 10 moves forward, and after moving forward by a distance Z, the push plate 23
The block 16 is moved forward.

As a result, the claw 19 attached to the block 16 is locked in the small hole 5 of the second part 2.
The second part 2 is advanced by a certain distance Y (see FIG. 4).

Thereafter, when the carrier plate 10 descends in the R' direction, the support member 36 descends due to the contraction force of the spring 42, and as shown in FIG. is inserted into the small hole 5 of. This pilot pin 38 has a tapered tip at its tip so as to correct a slight dimensional error (with respect to the Y dimension) that may occur during the transportation of the second part 2.
The diameter of the tip is set to a diameter that allows insertion with respect to the diameter of the small hole 5.

After that, when the carrier plate 10 has finished descending,
The second part 2 sent out from the end of the rail 31 is
A certain amount is cut by the upper blade 46 and the lower blade 47. Although not shown, the cut comb teeth portion 4 of the second component 2 is inserted into the hole 6 of the first component 1 by an insertion device.

Next, the carrier plate 10 that has descended as described above is
When moving backward in the Q' direction, the block 16 is moved by the spring 28
Due to the contraction force, it retreats following the carrier plate 10. At this time, the claw 19 attached to the block 16 rotates in the S' direction (clockwise) as shown in FIG. It retreats while touching the back side of 2.
Then, the block 16 comes into contact with a stopper screw 29 attached to the bearing 12 and stops. On this occasion,
As mentioned above, the tip of the claw 19 comes into contact with the back surface of the second component 2, and the contraction force of the spring 28 acts on the contact portion, so there is a possibility that the second component 2 can be pulled back by the claw 19. The pilot pin 38 is inserted into the small hole 5 of the second part 2 to prevent the second part 2 from being pulled back.

In addition, when the block 16 is completely returned, the claw 19 is moved counterclockwise (S direction) by the contraction force of the spring 28.
It rotates and enters the small hole 5 of the second part 2. Furthermore,
The carrier plate 10 is moved back by a distance Z to return to the position required for transporting the first part 1.

Therefore, in order to simultaneously transport the second parts 2 using the driving force of the carrier plate 10 for sequentially transporting the first parts 1, X=Y+Z must be established. For example, if the apparatus is adjusted so that X=Y+Z holds in order to assemble the first part 1 in which three holes 6 are provided, then
When assembling the first part 1 with 5 pieces, X=(Y
+2C) + (Z-2C), and is therefore fixed to the block 16 and carrier plate 10. Let the distance of the push plate 23 be (Z-2C). For this reason, generally the number of holes 6 is different (the number of poles is different).
Adjustments to the first part 1 can be made by retracting the carrier plate 10 completely and moving the block 16 to the stopper screw 2.
9, loosen the screws 25 of the push plate 23, move the push plate 23 backwards, and place a pre-prepared Z+ (multiple of C) or Z- (a multiple of C) between the push plate 23 and the block 16. Insert the adjustment spacer 48 (multiple) and tighten the screw 25 of the push plate 23 again.

"Effects of the Invention" As described above, the present invention includes a first part 1 having a hole 6 formed on its side surface, a small hole 5 formed in a strip part 3, and a comb tooth part 4 formed in the side surface of this strip part. In an apparatus for assembling a second part 2 and a second part 2 in the same direction to the first part 1, there is provided a transport rail 7 fixed to a base 9 and having a transport path 8 for transporting the first part 1, and a lower part of the rail 7. A plate-shaped carrier plate 10 is disposed perpendicularly to the base 9, and a plurality of claw members 11 are provided at a predetermined interval on the upper edge of the carrier plate 10 facing the conveyance rail 7. bearing 12,
13 are set upright facing each other, and two shafts 14 and 15 parallel to the carrier plate 10 are arranged vertically between the bearings, and at the upper ends of the bearings 12 and 13 there is a shaft for transporting the second component 2. A rail 31 having a passage 30 is disposed, and a slideable block 16 is supported on the shafts 14 and 15, and a claw 1 on the upper part of the block 16 is rotatable and locks into the small hole 5 of the second part 2.
Attach a movable plate 17 having a bearing 1
A tension type spring 28 is provided between the carrier plate 10 and the block 16 to constantly retract the carrier plate 10 and the block 16.
An L-shaped push plate 23 having an elongated hole 24 and an arm 23b that can freely come into contact with the block 16 is attached to the carrier plate 10, and the other bearing 1 is attached to the carrier plate 10.
A guide block 35 is fixed to the guide block 35, and the vertical part 36a of the support member 36 is supported by the block in a vertically movable manner, and a horizontal part 36b extends from the upper end of the vertical part onto the rail 31 of the second component. Horizontal part 3
Insert the pilot pin 3 into the hole 37 formed at the tip of 6b.
8 is inserted, and a tension type spring 42 is tensioned between the vertical portion 36a of the support member 36 and the guide block 35 to constantly bias the support member 36 downward, and the operation plate 45 is fixed to the carrier plate 10. The end portion of the vertical portion 36a is in contact with a rotatable bearing 43 at the lower end of the vertical portion 36a.

Therefore, it is possible to send a fixed amount of the second part to a fixed position in synchronization with the movement of the carrier plate for transferring the first part, and it is possible to accurately transfer the amount to the second part when changing the type of the first part. It is very easy to do.
