BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work aligning and feeding device for aligning and simultaneously feeding a large number of works in various product manufacturing processes.

[0002]

2. Description of the Related Art Conventionally, for example, in a process of manufacturing a camera, as a means for supplying a photoelectric tube for flash, a large number of photoelectric tubes (hereinafter referred to as "workpieces") are housed in a hopper having a slit at the bottom. By vibrating, the work was dropped from the slit onto the conveyor, and the work was sequentially supplied.

[0003]

However, since the above-mentioned supplying means supplies only one work piece at a time, work efficiency and production efficiency are poor, and since the work piece is vibrated, the adverse effect of the vibration is small. There was a problem.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a work aligning / feeding device which improves work efficiency and production efficiency by aligning and feeding a large number of works at the same time and which reduces vibration applied to the works. .

[0005]

In order to achieve the above-mentioned object, the present invention has a plurality of inverted conical recesses formed in an upper surface in an aligned manner, and upper and lower holes in which holes are formed from the bottom of the recesses to the lower surface. A movable aligner, a plurality of guides whose upper ends are inserted into the holes of the aligner and guide downwardly a work falling from each recess when the aligner moves upward, and a plurality of through holes corresponding to the guides. A pair of upper and lower fixed plates each having and a slide plate positioned between the fixed plates, and a set unit having a receiver in which the work receiving portions corresponding to the through holes of the lower fixed plate are aligned, Moreover, the through holes of each of the fixing plates are provided at positions that do not coincide with each other, and the through holes of the slide plates are alternately aligned with the through holes of each of the fixing plates by the reciprocating slide of the slide plate. And

[0006]

Operation: First, the work is supplied from the hopper or the like to the recesses of the aligner. The aligner is initially at the lower limit, so
The upper end of each guide projects into the recess. Therefore, the work is not disturbed by the upper end of the guide and does not fall into the hole.

When the aligner is moved upwards, the upper end of the guide is retracted from the recess and is positioned in the hole. Therefore, the workpieces in the recesses are dropped into the hole almost at the same time and are set by the guide. Be led to.

In the setting section, since the through hole of the slide plate is located at the same position as the through hole of the upper fixing plate, each falling work piece passes through the through hole of the upper fixing plate and passes through the through hole of the sliding plate. Stop. Then, since the slide plate slides by a hydraulic cylinder or the like, the through hole thereof coincides with the position of the through hole of the lower fixed plate.

Therefore, the works in the through holes of the slide plate fall at the same time and are housed in alignment with the receiving portions of the receiver. Therefore, the receiver may be taken out and the work may be supplied to the process requiring the work.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The illustrated embodiment shows an apparatus for aligning and supplying a rod-shaped work 1 such as a photoelectric tube.

In FIG. 1, reference numeral 2 denotes a hopper, the lower ends of both ends of which are fixed to a pair of moving bases 3. Reference numeral 4 is an intermediate base fixed to the frame, and a pair of screw rods 7 are rotatably installed on brackets 6 standing upright on both left and right ends thereof. The moving table 3 is screwed onto each of the screw rods 7. Therefore, when the screw rods 7 rotate at the same time, the moving bases 3 and the hoppers 2 reciprocate in the front-rear direction.

Numeral 8 is an aligner installed below the hopper 2 so as to be movable up and down, and a large number of inverted conical recesses 9 are formed on the upper surface thereof.
Are vertically and horizontally arranged at equal intervals, and holes 10 are formed at the bottom of each recess 9.

A pair of guide members 11 are attached to both end surfaces of the aligner 8, and guide rods 12 erected on the intermediate table 4 penetrate through the guide members 11 to guide them. A mounting plate 14 having a long hole 15 in the horizontal direction is fixed to the center of the end surface of the aligner 8.

Reference numeral 16 is a drive motor, 17 is a speed reducer, and a disc 18 is attached to its output shaft as shown in FIGS. A pin 19 is provided at an eccentric position of the disk 18, and the pin 19 is inserted into the elongated hole 15 of the mounting plate 14. Therefore, when the disk 18 is rotated by the operation of the motor 16, the pin 19 rotates while sliding in the elongated hole 15, so that the aligner 8 moves up and down via the mounting plate 14. .

Reference numeral 20 is a guide pipe for the work 1, which is attached through the intermediate table 4, and the upper end of the guide pipe is arranged by the aligner 8.
Is slidably inserted in the hole 10 of each recess 9.

A set portion 21 is installed below the guide pipe 20. As shown in FIG. 5, the setting portion 21 has a slide plate 24 and fixing plates 23 and 25 each having a number of through holes 23a, 24a and 25a corresponding to the number of the guide pipes 20 and a receiving hole 27 for receiving the work 1. It is composed of a receiver 28 in which receiving portions such as a cylinder are provided at equal intervals in the vertical and horizontal directions.

The slide plate 24 is arranged between the fixed plates 23 and 25, and reciprocally slides in the left-right direction by a hydraulic cylinder 29. Further, the through holes 23a and 25a of the respective fixing plates 23 and 25 are provided in a positional relationship that does not match each other. The receiver 28 can be slid in the front-rear direction, housed in the set portion 21, and pulled out.

Next, the operation of the work aligning and feeding device will be described. First, the hopper 2 accommodating a large number of works 1 periodically reciprocates, so that the works 1 drop into the recesses 9 of the aligner 8 from the slits at the bottom thereof.

In this case, since the aligner 8 is at the lower limit position as shown by the solid lines in FIGS. 2 and 3, the upper ends of the guide pipes 20 project into the recesses 9. Therefore, the work 1 is prevented from falling into the hole 10 by being obstructed by the upper end portion of the guide pipe 20.

Then, when the motor 16 operates and the disk 18 rotates, the pin 19 rotates and moves upward as shown by the chain double-dashed line in FIG. 8 moves up. As a result, the upper end of the guide pipe 20 is retracted from the recess 9 and is positioned in the hole 10, so that the work 1 in each recess 9 drops from the hole 10 into the guide pipe 20 almost at the same time, and the setting portion 21 Be led to.

In the setting unit 21, the slide plate 24
Since the through hole 24a of the fixed plate 23 is located at the same position as the through hole 23a of the upper fixed plate 23 as shown by the solid line in FIG. 5, each falling work piece 1 passes through the through hole 23a of the fixed plate 23 and slides on the slide plate. It stops at 24 through holes 24a.

Next, the slide plate 24 is attached to the hydraulic cylinder 2.
Since it slides to the left in FIG. 5 by 9, the through hole 24a coincides with the position of the through hole 25a of the lower fixing plate 25 as shown by the chain double-dashed line. Therefore, the respective works 1 existing in the through holes 24a fall at the same time and are accommodated in the respective receiving holes 27 of the receiver 28 in alignment. Therefore, the receiver 28 may be pulled out as shown in FIG. 1 and the work 1 may be supplied to a process requiring the work.

By repeating the above operation,
It becomes possible to align a large number of works 1 and supply them at the same time.

As a work to which the present invention is applied, rod-like bodies such as photocells and needles, ring bodies such as washers, hollow bodies and beads are suitable.

When the work is a ring body or a hollow body, a rod-shaped (core-shaped) guide that can penetrate the ring body or the hollow body may be used instead of the guide pipe 20.

[0026]

According to the present invention, since a large number of works can be aligned and supplied at the same time, work efficiency and production efficiency are greatly improved. Further, since the vibration applied to the work can be reduced, it is possible to prevent an adverse effect such as damage to the work due to the vibration.
