Description

Description: TECHNICAL FIELD The present invention relates to a method for aligning and assembling the center of an assembled article to the center of an article to be assembled.

[Prior Art] FIG. 5 shows an outline of a conventional method for assembling an assembled article to an article to be assembled. That is, in FIG. 5, it is moved to the X position by the assembling article moving claw 4 which performs intermittent reciprocating movement called so-called shuttle feeding, which operates intermittently in the order of (1) → (2) → (3) → (4). The supplied article to be assembled is moved to the Y position, and the assembly article 1 stopped by hitting the stopper 2 is gripped by a transfer device (not shown) and aligned with the article 3 to be assembled. I was wearing it. In this case, the assembling article 1 is assembled so that the center of the assembling article 3 coincides with the center of the assembling article 1.
Since the size of each is different as shown by the solid line and the imaginary line in Fig. 5, in order to match the centers, the assembled article that is stopped by hitting the stopper by the transfer device in Fig. 5 ,. Reprinted in order. here,
Is raised, is a movement for aligning the center of the assembled article 1 with the center of the article to be assembled 3, is the assembled article 1
Indicates the lateral movement of the article to be assembled 3 side, and the assembling of the article 1 to be assembled by descending the article 1 to be assembled.

[Problems to be Solved by the Invention] However, when the transfer device is transferred in the order of, as described above, the size of the assembled article as in the case of the solid line in FIG. Is different from above,
The movement for aligning the center of the assembling article with the center of the article to be assembled 3 in the middle of the sequence of ,,, is different, which causes a problem that the moving mechanism of the transfer device becomes extremely complicated.

The present invention has been made in view of the above-mentioned problems of the conventional example, and an object of the present invention is that the transfer device does not need to have a moving function for center alignment, and is not assembled. The center of the assembled article is located at the center of the assembled article according to the size of the assembled article or the size of the assembled article without changing the conveying stroke of the article moving claw. Another object of the present invention is to provide a method for assembling and assembling an assembled article to an article to be assembled that can be assembled together.

[Means for Solving the Problems] The method for assembling and assembling an assembled article to an assembled article according to the present invention is as follows. Is moved by a mounted article moving claw 4 mounted on a base body 5 that reciprocates with a constant transport stroke, and the mounted article 3 is placed at a position corresponding to the center of the mounted article 1 which is stopped by hitting a stopper 2. Is a method of assembling the assembled article 1 which is positioned at the center of the same and stopped by hitting the stopper 2, and the assembled article 1 is aligned with the center of the article 3 to be assembled. The base 5 can be fixed in a moving state.
The elastically pressing the assembled article moving claw 4 which is movable in the reciprocating direction toward the cam 6 side, and the position of the assembled article moving claw 4 with respect to the base body 5 is adjustable by the rotation of the cam 6. When the size of the assembling article 1 is different or the size of the assembling article 3 is different, the cam 6 is rotated to change the mounting position of the assembling article moving claw 4 to the base body 5 in the reciprocating direction. Thus, the starting position of the article-to-be-assembled moving claw 4 is changed according to the size of the article-to-be-assembled 1 or the size of the article-to-be-assembled 3 without changing the conveying stroke of the article-to-be-assembled moving claw 4. By adopting such a method, the problems of the conventional example described above are solved and the object of the present invention is achieved.

[Operation] When the size of the assembling article 1 is different or when the size of the assembling article 3 is different, the starting position of the assembling article moving claw 4 is changed correspondingly to the assembling article. The transfer stroke of the article moving claw 4 is moved by the center of the mounted article 1 which is stopped by hitting the stopper 2 and the mounted article moving claw 4 by moving the article 3 to be assembled while keeping a constant transport stroke. The center of the mounted article 3 can be automatically matched, and as a result, the center when the size of the mounted article 1 on the transfer device is different or when the size of the mounted article 3 is different. There is no need to provide a moving mechanism for alignment, and it is no longer necessary to change the transport stroke of the article moving nail 4 to be assembled. Then, the cam 6 rotatably attached to the base body 5 is fixed in an arbitrary rotating state, and the mounted article moving claw 4 movable in the reciprocating direction of the base body 5 is elastically moved toward the cam 6 side. Since the position of the article-to-be-assembled moving claw 4 relative to the base body 5 is adjustable by pressing and rotating the cam 6, the starting position of the article-to-be-assembled moving claw 4 is changed by a simple method of rotating the cam 6. be able to. Further, by using the cam 6 as a mechanism for changing the starting position without changing the stroke of the article-to-be-assembled moving claw 4, the mechanism is also extremely simplified.

[Embodiment] The present invention will be described in detail below with reference to the drawings shown in FIGS. 1 to 4.

The assembled article 1 is continuously supplied by a feeder, a conveyor or the like, and the assembled article 1 supplied by the feeder or the conveyor hits a stopper 2 so that the front end stops at a fixed position. The to-be-assembled article 3 is moved by the to-be-assembled article moving claw 4 which reciprocates with a constant transport stroke. The assembling article moving claw 4 is adapted to perform an intermittent reciprocating motion, which is so-called shuttle feeding, which intermittently operates in the order of (1) → (2) → (3) → (4) in FIG. . This assembling article moving claw 4
As shown in FIG. 2, a cam 6 is rotatably attached to the base body 5, and the cam 6 is rotatable by moving an operating portion 7 formed integrally with the cam 6 in the direction of the arrow in FIG. By tightening the screw 8, the cam 6 can be set in a non-rotatable fixed state in an arbitrary rotating state. The base 5 and the spring receiving seat 9 are fixed to the shaft 10 at a distance, and the mounted article moving claw 4 is slidably attached to the shaft 10 between the base 5 and the spring receiving seat 9. One end of the pin 11 inserted into the hole of the base 5 has the cam 6
The other end of the pin 11 hits the cam surface on the outer periphery of the object 11 and hits the article moving claw 4 to be assembled. A spring member 12 is interposed between the article-moving pawl 4 to be mounted and the spring receiving seat 9. The spring member 12 elastically presses the article-moving pawl 4 to be mounted toward the base body 5 side. ing. Therefore, when the operation part 7 is operated to rotate the cam 6 to change the cam surface on which the pin 11 abuts, the assembling article moving claw 4 is moved along the shaft 10. Then, as described above, the assembling article moving claw 4
By carrying out an intermittent reciprocating motion, which is so-called shuttle feeding, in which the base body 5 attached with is intermittently moved, the article moving claw 4 to be mounted is moved from (1) to (2) to (3) to (4) in FIG. This is an intermittent reciprocating motion called a so-called shuttle feed, which operates intermittently in the order of. Here, by rotating the cam 6 and changing the position of the article-moving claw 4 to be mounted with respect to the base body 5, the starting position of the article-moving claw 4 to be reciprocally moved can be changed. Thus, even if the starting position of the reciprocating movement of the article-to-be-assembled moving claw 4 is changed, the stroke of the reciprocating movement of the base body 5 to which the article-to-be-assembled moving claw 4 is attached does not change, so the article-to-be-moved moving claw 4 is moved. The reciprocating transport stroke of 4 is also the same.

According to the present invention, the article to be assembled 1 is supplied to the stopper 2 to stop it, and the article 3 to be assembled is pushed and moved by the article moving claw 4 which reciprocates with a constant transport stroke. Then, the assembled article 1 stopped by hitting the stopper 2 is grasped by the transfer device, lifted, moved laterally and lowered again to be assembled to the article 3 to be assembled. . In this case, according to the size of the article to be assembled 1 and the size of the article to be assembled 3, the center of the article to be assembled 3 at the position where the article is moved by the article moving claw 4 and stopped, and the article to be assembled The center of the assembling article 1 at a position where 1 hits the stopper 2 is stopped and the center of the assembling article 1 is adjusted. The center 6 is adjusted by rotating the cam 6 to convey the assembling article moving claw 4. The starting position of the article moving claw 4 to be mounted is adjusted without changing the stroke. For example, referring to FIG.
The case where the size of the article 3 to be assembled is the same and the size of the article 1 to be assembled is different from (a), (b) and (c) is shown.
When the size of the assembling article 1 is (a), the assembling article moving claw 4 is raised from the position A and is reciprocally moved in conjunction with the base body 5 and is supplied to the predetermined position by the prestage claw 13. It reaches the position B while pushing the attached article 3, and at this time, the center of the article to be assembled 3 comes into contact with the stopper 2 so as to coincide with the center of (a) which is the assembled article 1. ing. When the size of the assembling article 1 is (b), the assembling article moving claw 4 moves up from the A ′ position to reach the B ′ position while moving the assembling article 1 supplied to the predetermined position. However, at this time, the center of the article 3 to be assembled is made to coincide with the center of (b) which is the article 1 to be assembled which has stopped by hitting the stopper 2. In addition, the size of the assembled article 1 is (C)
In this case, the assembling article moving claw 4 rises from the A ″ position to reach the B ″ position while moving the assembling article 1 supplied to the predetermined position. The center of 3 corresponds to the center of (c) which is the assembled article 1 that has stopped by hitting the stopper 2. Here, the transport stroke L ₁ = L ₂ = L ₃ ,
Assuming that the dimensional differences of (a), (b), and (c) are l ₁ and l ₂ , respectively, the distance between A position and A ″ position and the distance between B position and B ″ position are (l ₁ + l ₂ ) / 2, A position and A '
The distance from the position and the distance from the B position to the B'position are respectively
a l _2/2. In FIG. 3, reference numeral 15 designates a rear stage claw, which is intermittently reciprocated the same distance as the base body 5 with a certain distance from the base body 5, and sends the article to be assembled 3 incorporating the article 1 to be assembled to the next step. It is like this.

In addition, the transport stroke of the article to be assembled 1 is [the minimum movement distance of the article 3 to be assembled (in the case of FIG. 3, the amount of movement of the article 3 to be assembled when the minimum article to be assembled)] + The difference in length between the maximum size and the minimum size of the assembled article 1 is 1/2] + [margin]. In FIG. 4, L is a transport stroke, and M is a moving distance of the article 3 to be assembled.

[Effects of the Invention] As described above, according to the present invention, when the size of the assembling article is different or the size of the assembling article is different, the object to be assembled is moved without changing the conveying stroke. Since the starting position of the assembling article moving claw is changed according to the size of the assembling article and the size of the assembling article, the assembling article moving claw transporting stroke of the assembling article moving nail is kept constant. By moving the, it is possible to automatically match the center of the assembling article that has stopped by hitting the stopper with the center of the assembling article moved by the assembling article moving claw, and the size of the assembling article. A special moving mechanism for centering is provided to the transfer device for transferring the assembled article to the assembled article when the size of the assembled article is different or the size of the assembled article is different. There is no need for this, and since there is no need to change the transfer stroke of the article moving claw 4 to be assembled, the center can be set by a simple method, and moreover, it can be freely rotated on the reciprocating base with a constant transfer stroke. The mounted cam can be fixed in any rotation state, and the assembly moving body that can move in the reciprocating direction of the base is elastically pressed toward the cam side and the cam is rotated to mount it on the base. The position of the article moving claw is adjustable, and when the size of the article to be assembled is different or the size of the article to be assembled is different, the cam is rotated to attach the article moving claw to the base body in the reciprocating direction. Since the position is changed, the stroke of reciprocation of the base body to which the article-moving pawl to be mounted is attached does not change even if the starting position of the article-to-be-assembled article moving pawl is changed. The moving stroke of the moving claw does not change, so that the starting position of the moving article moving claw can be changed according to the size of the assembled article or the size of the assembled article without changing the transport stroke of the moving article moving claw. In other words, the center of the article to be assembled and the center of the article to be assembled can be easily and surely matched with each other, and the starting position can be changed without changing the stroke of the article moving claw. A simple mechanism of providing a cam on the base body as a mechanism for changing the mounting position and adjusting the mounting position of the article-moving pawl to be mounted on the base body by rotating the cam, and changing the stroke of the article-moving pawl to be mounted Even if the starting position is changed, it can be easily performed by rotating the cam.
