DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for automatically supplying cylindrical or substantially cylindrical parts and cylindrical or substantially cylindrical parts. More particularly, the present invention relates to an automatic supply apparatus for a soft or lightweight cylindrical or substantially cylindrical part which is made of a plastic material and has a small weight and a small weight.

[0002]

2. Description of the Related Art Conventionally, as an automatic supply device for automatically supplying components integrated in a different direction to a machining process while directing the components one by one to a fixed direction, there is an automatic supply device utilizing vibration. There is a device. This vibration type automatic feeder captures the uneven shape of a part of the part, forms a groove with a shape almost similar to the uneven shape of the part on the rail, and applies it to the part while changing the direction etc. by applying vibration The component is moved in the direction of the rail, and only the component that is oriented in a certain direction and accommodated in the groove of the rail moves along the rail by vibration and is supplied to the machining process. That is, the grooves formed in the rails determine the direction of the parts and at the same time serve as a guide for moving the parts in the same direction. Parts that do not fit in the groove of the rail are repelled from the rail by vibration, and are repeated until vibration is obtained again and fit in the groove of the rail.

[0003] This vibration type automatic feeding device has a shape having irregularities and is easy to provide a guide for determining the above-mentioned directionality, a part which is stationary on a flat surface and which is easily moved by vibration, a relatively small size, and particularly a length. Can be effectively used for parts with relatively short length.

[0004]

On the other hand, on the other hand, a component having a symmetrical shape without any irregularities, a component which is very large or very long and whose direction is hardly changed by vibration,
A vibration-type automatic supply device is not suitable for a component having a round shape and easy rolling, a component having a soft shape and easy deformation, and the like.

[0005] In particular, a soft or lightweight cylindrical or substantially cylindrical part, such as a plastic container, having a small weight for its size is easily deformed, and absorbs vibration itself and does not move. No automatic feeder is available.

The present invention has been made in view of the above problems, and an object of the present invention is to provide an automatic supply device for a cylindrical or substantially cylindrical component which has a round shape and is easy to roll, and is soft and lightweight. It is in. The object of the apparatus is to be applicable to a light-weight cylindrical or substantially cylindrical part.

[0007]

SUMMARY OF THE INVENTION According to the present invention, a cylindrical or substantially cylindrical part or a cylindrical or substantially cylindrical part integrated in a state in which the directions are scattered is machined by directing the direction thereof one by one in a fixed direction. In the automatic supply device for automatically supplying to a process, the automatic supply device has a rotary drum formed with a plurality of negative pressure suction holes for adsorbing and fixing the parts in parallel and in parallel to a horizontal surface of an inner peripheral wall thereof. The automatic feeding device is provided with a hopper on a side surface of the drum for stacking the components in the drum.

Further, at least two negative pressure suction holes are provided in a horizontal plane of an inner peripheral wall parallel to a horizontal center axis of the drum.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION A cylindrical or substantially cylindrical part or a cylindrical or substantially cylindrical part having a round outer periphery and being lightweight and easy to roll is put in a cylindrical drum, and the drum is rotated around its horizontal axis. Combined with the rotating action of the component itself, it becomes easier to settle down in a state parallel to the horizontal surface of the drum inner peripheral wall. Utilizing this, the present invention provides a hopper on the side surface of the rotating drum for accumulating many components in the drum. With the structure in which the components are accumulated by the inner peripheral wall of the hopper and the drum, the components accumulated there are arranged in parallel and parallel to the horizontal plane of the inner peripheral wall of the drum when the drum is concentrically rotated.

Furthermore, by providing a small negative pressure suction hole communicating with the negative pressure space area of the drum outer peripheral area on the drum wall surface, the components are drawn to the negative pressure suction hole, are sucked in parallel, and are fixed. When the component is subjected to the suction force action in the drum, its posture is corrected toward the state parallel to the horizontal surface of the inner peripheral wall, and when the component comes into close contact with the suction hole in the wall, the suction force is maximally applied and becomes stationary. I do. That is, when the component is parallel to the horizontal surface of the inner peripheral wall, the suction force is maximized, and the component is sucked and stopped to be in a completely parallel state. At this time, if there are two or more suction holes in the horizontal plane of the inner peripheral wall, the parts which are almost parallel will be sucked by two or more surfaces, so that they are quickly corrected toward the parallel state. That is, the parallel state is corrected in a short time, and the parallel suction is performed.

Since a plurality of the suction holes are formed at regular intervals along the curved wall surface, the parallel suction is performed in a short time at each suction hole portion. Alignment fixation is promoted. The parts thus fixed by suction are sequentially moved to above the drum by rotation of the drum.

[0012] Further, as the suction-fixed part moves due to the rotation of the drum, the part that has not yet been sucked by the suction-fixed part is moved by the movement of the suction-fixed part and rolls. However, the action of rolling other parts one after another occurs. That is, a phenomenon of stirring occurs, and further parallelization is promoted.

As described in detail above, the present invention provides a hopper for accumulating a large number of components in a rotary drum, and providing two or more negative pressure suction holes on a horizontal surface of the inner peripheral wall of the drum, thereby making it possible to form the drum. Many components in the drum are parallelized and aligned in a short time by utilizing the rotating action, the suction action on the inner peripheral wall surface of the drum, and the stirring action of the suction component. At the same time, the parts which are fixed by suction to the inner peripheral wall of the drum in parallel are rotated and moved to a place where the parts can be easily taken out by using the rotation of the drum.

As described above, the suction components which have been sequentially moved to the upper part of the drum with the rotation of the drum are released at a place where it is easy to take out the negative pressure suction, dropped, and placed on a tray or the like. Can be. In addition, a direction detecting sensor for a suction component is mounted in the drum to determine the suction direction, and based on the determination signal, the tray rotates in a specified direction to align the components. In addition, parts having such aligned directions can be supplied to the machining process via the unloading device one by one.
