DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for assembling an article by aligning the center of the article with the center of the article.

[Prior Art] A conventional method for assembling an article to an article is schematically shown in FIG. That is, in Figure 5, (1
) → (2) → (3) → (4) The assembled workpiece is fed to the When the article is moved to the X position and stopped when it hits the stopper 2, the article 1 is grabbed by a transfer device (not shown), and the article to be assembled is aligned with the article 3 and assembled. in this case,
The assembly is done so that the center of article 3 coincides with the center of article 1. However, when assembling, the size of article 1 is different, as shown by the solid line and the imaginary line in Figure 5. , transposed to match the center! ! The 4-pack items that have hit the stopper and are stopped due to loading are being transferred in the order of ■, ■, ■, ■ in Figure 5. here,
■ indicates soil quality, ■ indicates assembly to align the center of article 1 with the center of article 3 to be assembled, ■ indicates assembly indicates article 1
The assembling shown in ``■'' indicates a lateral movement toward the article 3, and the assembling ``■'' indicates that the article 1 is lowered, and the assembling ``■'' indicates introduction to the article 3.

[Problem to be Solved by the Invention 1] However, when transferring the transfer device in the order of ■, ■, ■, ■ as described above, in the case of the solid line in Fig. 5, it is difficult to assemble as in the case of the imaginary line. If the size of the item is different, the above ■,■
, ■, During assembly in the middle of the movement in the order of ■, the movement to align the center of the article with the center of article 3 is different, so the movement mechanism of the transfer device is not changed and is complicated. There is a problem with becoming

The present invention was invented in view of the problems of the prior art described above, and its purpose is to move 1'l! for centering the transfer device! In addition, it is possible to easily assemble articles of different sizes or to assemble articles of different sizes without changing the conveyance stroke of the single article moving claw in plate assembly A. Depending on the different items, the assembler can align the center of the article with the center of the article, and the assembler can assemble it to the article. There is something to do.

[Means for Solving the Problems 1] The method of assembling the object of the present invention is assembling the object into an article, and assembling the object and aligning the object. For assembly, the article 3 is reciprocated with a constant conveyance stroke.The article to be assembled is moved by the article moving claw 4 and stopped when it hits the stopper 2.For assembly, the article 3 is moved to a position that coincides with the center of the article 1. This is a method of assembling by positioning the center of article 3 and stopping it when it hits stopper 2, aligning article 1 with the center of article 3 to be assembled. In the case of different sizes of articles 3 or articles 3 to be assembled, the assembler changes the starting position of the article moving claw 4 to the starting position of the article 1 without changing the conveyance stroke of the article moving claw 4. The method is characterized in that the size and the assembly target are changed depending on the size of the article 3, and by adopting such a method, the above-mentioned problems of the conventional example can be solved and the object of the present invention can be achieved. This is what I did.

[Function] Therefore, when the size of the article 1 differs during assembly, or when the size of the article 3 differs between the assemblers and the assembler, the assembler changes the starting position of the article moving claw 4 accordingly. , the conveying stroke of the article moving claw 4 of the assembled object was maintained at a constant conveying stroke *The assembled object moved the object 3, and the assembled object, which had stopped when it hit the stopper 2, moved between the center of the object 1 and the object. The object to be assembled is the object 3, which is moved by the object moving claw 4.
As a result, it is possible to automatically match the center of the item 1 with the center of the item 1 when the size of the item 1 is different, or when it is assembled to the transfer device.
There is no need to provide a moving mechanism for centering the articles 3 when the sizes of the articles 3 are different, and there is no need to change the conveyance stroke of the article moving claw 4 when the articles 3 are assembled.

[Example 1] The present invention will be described in detail below based on the drawings shown in FIGS. 1 to 4.

The assembly is such that the article 1 is continuously fed by a feeder, conveyor, etc., and the article 1 is supplied by the feeder or conveyor in such a way that the tip hits the stopper 2 and stops at the fixed position value. . The assembled article 3 is moved by an article moving claw 4 in which the article 3 reciprocates with a constant conveyance stroke. For assembly, the article moving claw 4 is the first
It performs intermittent reciprocating motion, which is called shuttle feed, in which it moves intermittently in the order of (1)→(2)→(3)→(4) in the figure. To be assembled, the article moving claw 4 has a cam 6 rotatably attached to the base body 5 as shown in FIG. The cam 6 can be freely rotated by moving the
By tightening the screw 8, the cam 6 can be placed in a fixed state where it cannot rotate in any rotational state.

The base body 5 and the spring receiver are fixed to the pongee 10 at a distance from the seat 9, and the base body 5 and the spring receiver are assembled to the shaft 10 between the seat 9 so that the article moving claw 4 can slide freely. One end of the pin 11 inserted into the hole of the base 5 is connected to the cam 6.
The other end of the pin 11 is in contact with the cam surface on the outer periphery of the pin 11 and the other end of the pin 11 is in contact with the article moving claw 4 in the assembled state. There is an intervening spring material 12 to assemble the article moving claw 4 to the base 5.
It is pressed elastically to the side. Therefore, when the operating portion 7 is operated to rotate the cam 6 and the cam surface that the pin 11 touches changes, the assembled item moving claw 4 is moved along the shaft 10. As described above, the assembly is carried out by the base body 5 to which the article moving claws 4 are attached performs intermittent reciprocating motions called shuttle feeding. (1) → (2) → (3) → (4
), which performs an intermittent reciprocating motion called shuttle feeding. Here, by rotating the cam 6 and changing the position of the article moving claw 4 to be assembled onto the base body 5, the article moving claw 4 can be assembled to perform the above-mentioned reciprocating movement.
In this way, even if the starting position of the reciprocating movement of the article moving claw 4 is changed, the assembled object will not be able to move the base 5 to which the article moving claw 4 is attached. Since the reciprocating stroke does not change, the reciprocating transport stroke of the assembled article moving claw 4 also does not change.

Therefore, in the present invention, the assembly is performed by supplying the article 1 and stopping it by hitting the stopper 2, and at the same time, the article 3 to be assembled is
The assembled object, which reciprocates with a constant conveyance stroke, is pushed and moved by the article moving claw 4 and stopped at a predetermined position.Then, when the assembled object hits the stopper 2 and is stopped, the object 1 is grabbed by the transfer device. The object to be assembled is assembled into the article 3 by being lifted up, moved sideways, and lowered again. In this case, the assembly is performed in advance according to the size of the article 1, and the to-be-assembled is determined according to the size of the article 3. The assembly is performed so that the center of the article 1 coincides with the center of the article 1 at the position where the article 1 hits the stopper 2, and the center alignment is adjusted by rotating the cam 6. For example, in Fig. 3, the size of the article 3 to be assembled is adjusted without changing the conveyance stroke of the article moving claw 4. The size of item 1 is the same and the size of the assembly is (
Cases different from (a), (b), and (c) are shown below. Then, when the size of the article 1 is (A), the article to be assembled is supplied to a predetermined position by the pre-stage pawl 13 that moves up from the A position and moves back and forth in conjunction with the base body 5. The assembled object does not push the object 3 until it reaches the B position. At this time, the center of the object 3 hits the stopper 2 and the assembled object 1 is the center of object 1 (a). If the size of the article 1 is (B), then the article moving claw 4 is raised from the A' position and is supplied to the predetermined position. reaches position B' while moving article 1, but at this time, the assembled object 3 is stopped so that the center of article 3 hits the stopper 2. It has become. In addition, when the size of the article 1 is (c), the article moving claw 4 is raised from the A" position and is supplied to the predetermined position. It reaches position B', but at this time the object to be assembled is item 3.
The assembly in which the center of 2 hits the stop 7 bar 2 and is stopped coincides with the center of item 1 (c). Here, the conveyance stroke L, = L2 = L,
The dimensional difference between (a), (b), and (c) is 11.12, respectively.
Then, the distance between the person's position and A' position and the distance between B position and B'
The distance between the two positions is (1t +12)/2, and the distance between the A position and the A' position and the distance between the B position and the B' position are respectively! , /2. In FIG. 3, reference numeral 15 is a rear-stage pawl that is separated from the base 5 by a certain distance and makes intermittent reciprocating movements in the same way as the base 5, and is used to send the plate-assembled article 3 into which the assembled article 1 has been incorporated to the next process. It has become.

In addition, the conveyance stroke of the article 1 to be assembled is [minimum movement and immediate separation of the article 3 to be assembled (in the case of Fig. 3, the conveyance stroke of the article 1 to be assembled is
(movement when transporting) 1 + assembly is 1/2 of the difference in length between the largest size and the smallest size of article 1] + [
The margin is 1. In FIG. 4, L is the conveyance stroke, M is the moving distance of the article 3 to be assembled, and C is the assembly position.

[Effect of the Invention 1 As described above, in the present invention, when the assembled articles are of different sizes or the assembled articles are of different sizes, the assembled articles change the conveyance stroke of the article moving claw. When assembling, the starting position of the article moving claw is changed according to the size of the article, and the assembler changes the starting position of the article moving claw according to the size of the article. By moving the assembled items while maintaining the
The center of the article can be automatically aligned with the center of the article when the assembly is stopped by hitting the stopper, and the center of the article is automatically aligned with the center of the article when the assembly is moved by the article moving claw. There is no need to provide a special moving mechanism for center alignment in the transfer fHift for transferring the assembled article to the assembled article when the sizes of the articles are different. When assembling, there is no need to change the conveyance stroke of the article moving claw 4, and the centering can be done in a simple manner, making it lightweight.
