Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a parts aligning machine separating section for storing rectangular drawn parts forming edges in a magazine.

A conventional parts alignment machine will be explained with reference to FIGS. 1 and 2.

Figure 1 shows an SMM (sealed multi-contact switch) used in space-divided electronic exchanges.
1 is a schematic perspective view of the main parts of press processing equipment for mass production of sealing covers for multi-contact matrix switches. The material is fed into the transfer mold 2 from the direction of arrow A, where it is subjected to multiple drawing processes, and then passed through the direction of arrow B.
transported in the direction. The cover 4 that has been processed is discharged in the direction of arrow C, placed on the belt conveyor 3, and moved in the direction of arrow D. It falls in the direction of arrow E at the end of the belt conveyor 3 and is stored in the transportation magazine 5. The magazine 5 aligns and accommodates the covers 4 while moving at a constant pitch in the direction of arrow F. Second
The figure is an enlarged perspective view of the cover. The material is composed of 42% nickel-iron alloy, and a rim 4a is formed around the periphery, the width of which is approximately 0.65 mm. In assembling the SMM switch, this edge 4a is welded to seal the element.

Conventionally, the boxes were received unaligned from the belt conveyor 3 and aligned during assembly work. Furthermore, with the implementation of automation of assembly work, magazines 5 that can be accommodated in an aligned manner have come to be used, but the relative position of the cover 4 that is ejected from the belt conveyor 3 and falls relative to the magazine 5 is not necessarily constant, and the alignment within the magazine is not necessarily constant. Containment is not easy.

An object of the present invention is to provide a structure of a separating section of a parts aligning machine that automates the above-mentioned work. That is, the lower end of the chute that guides and vertically aligns and accommodates the edge of the rectangular aperture part forming the edge is provided with a slope that guides both sides of the rectangular aperture part to the correct position, It is equipped with a hook that clamps and locks the ridges on both sides of the lower part, and the position of the hook is regulated by a spring and a stopper, and when the rectangular drawing part is subjected to sliding pressure, the slope that releases the lock of the hook is used as the hook. The automatic insertion into the magazine can be realized reliably by the structure of the parts aligning machine separating part, which is characterized in that it is provided in the parts aligning machine separating part.

Examples according to the present invention will be described in detail below. Note that the same reference numerals in the figures from FIG. 1 to FIG. 6 indicate the same parts.

FIG. 3 is a schematic perspective view of the main parts of the separating section structure of the parts aligning machine according to the present invention. The cover 4 that has been transferred on the belt conveyor 3 is transferred to the belt conveyor 3
Guide plate 1 when falling in the direction of arrow E at the end of
0 and falls into chute 11. Shoot 1
1 holds the edges 4a protruding from both left and right sides of the cover 4 and guides the cover 4 to fall. The fallen cover 4 descends along an inverted V-shaped slight slope 12a inside two claws 12 rotatably fixed to the chute 11, and is attached to a stopper 15 by a spring 1.
The slope of the hook at the tip of the two claws pressed at 6 1
It is supported by 2b as if being held. The covers 4 transferred by the belt conveyor 3 are sequentially arranged and housed in the chute 11, but since the edges 4a contact each other, the edges 4b of the rectangular constricted portion of the cover 4
are not in contact and maintain a slight gap α.

Next, the vacuum suction head 13 suctions the cover 4 held at the lowest end of the chute 11, and pushes the cover 4 downward while opening the two claws 12 against the spring 16 that presses the claws 12. Push it between the partitions.

FIG. 4 is a structural front view showing the cover holding function of the claw. The pawl 12 is fixed by a shaft 14 and is rotatable. However, for the stopper 15, the spring 16
Since the two claws 12 apply pressure, the width of the hook corner portions of the two claws 12 is maintained at a width that can gently accommodate the width B of the corner constriction portion of the cover 4. In addition, the inner surface 12a of the claw 12 is shaped like an inverted V at an angle β (4° in this embodiment).
It has an inclination of , and is formed to serve as a guide for the width B of the corner constriction portion when the cover 4 falls.

The hook part of the claw 12 has a corner cut into a V-shape and has an angle γ.
(45° in this embodiment).
Therefore, when the cover 4 is pushed down in the direction of arrow G, the rounded corner 4c of the cover 4 can push the inclined surface 12c against the spring 16 and pass between the spreading claws 12. The dotted line in the figure indicates the position of the claw 12 when the cover 4 passes.

FIG. 5 is an explanatory diagram showing the operation sequence of the parts aligning machine separating section according to the present invention. Figure A shows the state before the cover falls, Figure B shows the state in which the cover is held after it has fallen, Figure C shows the intermediate state when one cover is pressed down, and Figure D shows the state when magazine storage is completed.

In Fig. 4, the two claws 12 are stationary, maintaining a width A that accommodates the width B of the corner constriction portion of the cover 4, as explained in Fig. 4. Cover 4 has not fallen yet.

At step B, the cover 4 falls, and the lowermost cover 4 is held by the hooks 12b on the two inner corners. The vacuum suction head 13 suctions the lowermost cover 4.

In Figure C, the cover 4 sucked by the vacuum suction head 13 presses the slope 12c of the hook 12b, overcomes the pressure of the springs 16 of the two claws 12, and is pulled out downward in the direction of arrow G while being pushed out. Immediately after pulling out, the two claws 12 close to prevent the next cover 4 from falling.

In Figure 2, the vacuum suction head 13 moved in the direction of arrow G moves the cover 4 to the partition 5a of the magazine 5.
After the vacuum suction is released, the cover 4 is detached from the cover 4 and returned to its original state.

FIG. 6 is an explanatory diagram showing the operation of the vacuum suction head. As explained in Fig. 4, descend in the direction of arrow G, place the cover 4 in the magazine 5, release the vacuum suction,
It retreats in the direction of arrow H, rises in the direction of arrow J, moves again in the direction of arrow K, and performs vacuum suction on the next cover 4. During this cycle, the magazine 5 moves 1 in the direction of arrow F.
It moves by the pitch and waits for the next cover 4 to be accommodated. Note that the chute 11 is provided with a photodetector, which operates by determining the presence or absence of the cover 4.
The vacuum suction head 13 is driven by a normal cam mechanism, so its explanation will be omitted.

In this embodiment, the pawl 12 is fixed to the shaft 14, but depending on the structure, it may also be effective to directly utilize the spring itself as the pawl. Also, instead of vacuum suction, it is acceptable to use electromagnetism or various mechanical clamping mechanisms.

According to the present invention, the covers that have been pressed can be automatically housed and aligned, so they can be automatically supplied from the magazine to an automatic welding machine during automatic assembly work. In addition, since the press processing work order is aligned, abnormalities in processing can be detected and processed accurately, and quality is stable. Since the mechanism according to the present invention is extremely simple, its operation is reliable, reliable, and economically advantageous.

Although the embodiment of the present invention was applied to the cover of an SMM switch, it is presumed that by changing the shape of the claw, it can be widely applied not only to other pressed products but also to general products. is wide.
