Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a component supply device, and more particularly to a component supply device that continuously supplies supply components that are almost rotationally symmetrical in shape and have protrusions partially aligned in a constant posture.

Conventionally, a device that continuously supplies parts having a partially asymmetrical shape to a fixed position in a fixed position has been used, for example, in a guide section of a supply mechanism such as a parts feeder. A device that excludes parts and allows only the supplied parts in the desired posture to pass through, or an optical sensor or the like detects the posture of the supplied parts that have been guided to the tip in various postures, and a posture correction mechanism or the like is used to maintain a constant position. There is a device that aligns the body in this position. However, the former device is only possible if the supplied parts have a significant asymmetry in shape or weight distribution, but not if the asymmetry is slight. The latter device has the disadvantage that it is extremely complicated and expensive because it requires a mechanism to actively detect the attitude of the supplied parts using a sensor and further control the attitude.

The purpose of this invention is to eliminate these drawbacks,
It is an object of the present invention to provide an inexpensive and highly reliable component supply device capable of supplying components having a substantially rotationally symmetrical shape and having small protrusions in a part in a constant posture.

The present invention continuously supplies a large number of parts that are almost rotationally symmetrical in shape and have protrusions in some parts in a line in a guide groove, stops at the tip, and keeps the direction from the tip to the protrusion constant. A parts supply device for supplying parts in a conveyance path, a supply mechanism for continuously supplying parts to be supplied in one line in a guide groove of a conveyance path, a pin having a shape whose tip engages and holds the parts to be supplied, a drive mechanism that drives the pin up and down; a work holder that presses down a second supply component counted from the tip that is supplied by the supply mechanism; and a supply component held by the pin is pushed up by the drive mechanism; The component supply device is characterized by comprising a stopper provided at a position where a protrusion of the supply component rotated by the rotation mechanism is locked.

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1a is a plan view showing a component supply device according to an embodiment of the present invention, and FIG. 1b is a side view showing a component supply device according to an embodiment of the present invention.

In these figures, a protrusion 91 is formed on the cylindrical outer wall.
The supply part 9 having the cylinder 1 is arranged in the guide groove 12 with the central axis of the cylinder aligned in the bowl feeder 11.
The guide groove 12 is continuously supplied in one line to the abutting portion 13 at the tip of the guide groove 12 . Guide groove 1
2 is provided with a cover 14 on the top surface to prevent the supply component 9 from dissipating, but the supply component 91 located at the most extreme position and the adjacent supply component 92 are shaped so that their top surfaces are exposed. There is. A through hole 15 is provided at the bottom surface of the leading edge of the guide groove 12 to a size that prevents the supply component 91 from falling. On the underside of the most distal supply part 91 there is provided a pin 2 whose tip 21 is shaped to engage with the inner wall and lower surface of the supply part 9 . The pin 2 is directly connected to a rotating shaft 41 of a rotating mechanism 4 consisting of a motor that makes one rotation in a fixed direction and then stops. The rotation mechanism 4 is fixed to a drive mechanism 3 that is driven by a linear actuator 31 in the vertical direction through a bearing 32 .

The most advanced supply component 91 is held by the tip 21 of the pin 2 and lifted upward by the drive mechanism 3 driving upward, and the frictional force with the tip 21 is caused by the rotation of the rotation mechanism 4. Rotate with.
The workpiece holder 5 rotatably supported by a part of the guide groove 12 is provided in a position to press the second supply component 92 counted from the tip, and the supply component 91 is held at the tip by the drive mechanism 3. The stopper 6 has a positional relationship that allows it to lock the protrusion 911 when it is raised and rotated by the rotation mechanism 4. An arm 33 is fixed to the drive mechanism 3, and a tension spring 35 and a workpiece presser 5 are connected between the drive mechanism 3 and the workpiece presser 5.
It has a pusher 34 that contacts the. The pusher 34 has a length such that the work holder 5 presses the supply part 92 before the pin 2 rises and comes into contact with the supply part 91, and the work holder 5 separates from the supply part 92 when the pin 2 finishes descending. regulated.

Therefore, when the pin 2 starts to rise, the second supply part 92 is fixed by the work holder 5 on the way, and the pin 2 further rises and is lifted to a height where the first supply part 91 is removed from the guide groove 12. Next, when the rotation mechanism 4 starts rotating, the supply part 91
The protrusion 911 hits the stopper 6, the supply part 91 stops rotating from then on, and the pin 2 touches the supply part 92.
Rotates 360° while creating friction between the In this state, the directions of the protrusions 911 are uniform, and the supplied part 91 can be transferred to another device (not shown) that grips it. When the supply part 91 is removed from the top of the pin 2, the pin 2 is lowered, and the work holder 5 is separated from the second supply part 92 by the pusher 34 on the way, and each supply part 9 is removed by the supply mechanism 1.
is sent forward one by one to reach the starting state.

In the above, the supply part 9 has a cylindrical shape and has a protrusion 9 on the outer wall.
11, but the tip 2 of the pin 2
It goes without saying that the present invention can be applied to other rotationally symmetrical supply parts having some protruding parts by simply changing the shape of part 1 and the dimensions and positions of the other parts.

As explained above, according to the present invention, in a component supply device that continuously supplies supplied components in one row, the supplied component at the tip is lifted from below while the second supplied component from the tip is fixed. By using frictional force and applying the protruding part of the supplied part to a stopper provided at an appropriate position, it is possible to handle supplied parts with minute protruding parts that cannot be aligned with a general parts feeder, and moreover, it is possible to handle supplied parts with minute protruding parts that cannot be aligned with a general parts feeder. Effects such as a simple mechanism that does not require a complicated and sophisticated sensor to detect the orientation of the part can be obtained.
