Description

[Detailed description of the invention] [Summary] The present invention relates to a washer alignment mechanism that automates the work of aligning and storing randomly stored washers by piercing them through a single storage pin in preparation for the next process. a posture correction pipe that corrects the posture to a horizontal posture, a correction pipe drive mechanism that provides rotational movement to the posture correction pipe, and the washer that is disposed directly below a washer delivery port of the posture correction pipe and that falls from the delivery port. and a storage pin that is inserted through the hole to be received and aligned.

[Industrial application field]

Many washers and bushings are used in recent electronic devices. However, if these parts are to be loaded into an automatic machine and incorporated into the target product, they must be reloaded into the appropriate container.
These must be supplied to the assembly process in an orderly manner.

The present invention relates to a washer alignment mechanism used as a preparation process for mounting washers on an automatic machine.

[Conventional technology]

FIG. 2 is a perspective view for explaining a conventional washer alignment method.

As shown in the figure, in the past, the washer 2 was inserted one by one into the storage pin 3 set up on the table 3a, for example, by grasping and inserting the washer 2 with one's fingers or tweezers.

[Problem that the invention attempts to solve]

However, the above method is extremely monotonous and requires manual work for each piece, resulting in extremely inefficient work.

The present invention was made in order to improve work efficiency by automating the above-mentioned washer alignment work, which previously relied on manual work.

[Means for solving problems]

As shown in FIG. 1, the washer aligning mechanism according to the present invention comprises a posture correcting pipe 4 having a washer feeding port connected to a hopper 1 in the upper part and a washer feeding port 5 in the lower part, and the posture correcting pipe 4. A correction pipe drive mechanism 15 that provides a rotational movement about the axis of the pipe 4, and a correction pipe drive mechanism 15 that is arranged directly below the washer delivery port 5 of the posture correction pipe 4, and a correcting pipe drive mechanism 15 that provides a rotational movement about the axis of the pipe 4; The storage pin pierces the hole of the washer 2 to be sent out and aligns the washers 2 so that they overlap with each other.

[Effect]

In the washer alignment mechanism of the present invention, the storage pin 3 for storing the washer 2 is arranged with its tip inserted into the washer delivery port 5 of the posture correction pipe 4. The washers 2 whose posture has been corrected to a horizontal posture and are sent out are automatically pierced through the holes by the storage pins 3 and stored in a mutually overlapping manner.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a sectional side view showing an embodiment of the washer alignment mechanism according to the present invention.

However, the same symbols throughout the drawings indicate the same thing.

As shown in the figure, the washer aligning mechanism of the present invention includes a posture correcting pipe 4 having a hopper 1 at the upper end and a washer outlet 5 at the lower end, and a posture correcting pipe 4 that is connected vertically and downwardly. A correction pipe drive mechanism 15 comprising a pair of bearings 6 rotatably supported at both ends, a motor 7 and a gear mechanism 8 for rotating the posture correction pipe 4 in the direction of arrow A or A', and the washer feeder. The storage pin 3 is arranged directly below the outlet 5.

The bearing 6 and the motor 7 are mounted on a support 9, and the support 9 is fixed on a base 10.

Further, the storage pin 3 is located at a predetermined position on the base 10.
will also be placed.

The operation of the washer alignment mechanism will be explained below.

When the washer 2 is put into the hopper 1 provided at the upper end of the posture correction pipe 4 which is rotated by the correction pipe drive mechanism 15, the washer 2 gradually corrects the posture from the hopper 1 due to its own weight. Move in the 4 directions of the pipe.

Then, it touches the inner wall 4a of the rotating posture correction pipe 4, and as it rotates, it gradually falls downward under its own weight.

During this process, the washer 2 is corrected in a horizontal position by centrifugal force, and maintains a completely horizontal position when delivered from the washer delivery port 5.

The storage pins 3 disposed directly below the washer delivery port 5 are received in a skewered manner, and the storage pins 3 are aligned and housed.

The difference in dimension between the outer diameter d of the washer 2 and the inner diameter D of the posture correction pipe 4 is determined by taking into consideration the effective length L of the correction section of the correction pipe 4, the rotational speed of the correction pipe 4, and the like.

Furthermore, it goes without saying that there is no difference in the posture correcting effect of the washer 2 regardless of whether the posture correcting pipe 4 is rotated in the left or right direction.

[Effect of idea]

As is clear from the above explanation, the washer aligning mechanism according to the present invention is troublesome and inefficient because it can automatically and efficiently store washers and members of the same shape as the washers in a skewered state on the storage pin. Washer alignment work becomes significantly more efficient.
