[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parts supply device for supplying parts on an assembly line or the like.

[0002]

2. Description of the Related Art Conventionally, as a component stirring mechanism provided in a component supply device, for example, Japanese Patent Laid-Open No. 58-148129 has been disclosed
There is an invention described in the publication. FIG. 18 and FIG.
9 shows. FIG. 18 is a cross-sectional view showing a state in which the guide cylinder 53 and the pin 54 are raised to stir the component 55 by the pin 54, and FIG. 19 is shown in FIG. It is sectional drawing which shows the state which the component 55 enters.

Inside a hopper 51 having a funnel-shaped lowest part with a drop hole, a guide cylinder 53 having a component receiving port 52 at its upper end and a component 55 attached around the guide cylinder 53 are agitated. It is configured to move up and down integrally with the rotating pin 54. With the above configuration, the guide tube 5
When the 3 and the pin 54 are integrally moved up and down inside the hopper 51, the pin 54 provided around the guide cylinder 53 agitates the component 55 in the hopper 51 and moves the component 55 to the guide cylinder 5.
It is made easy to enter into the component receiving port 52 provided at the upper end of 3.

[0004]

However, the agitating mechanism of the parts in the prior art described above has the following drawbacks. That is, the pin 54 that serves as the stirring mechanism is the guide tube 5
It moves up and down in conjunction with 3, and stirs the component 55. But,
Since the shape of the stirring mechanism is the pin 54, and its operation is vertical movement, the pin 54 cannot enter the gap between the parts 55 and 55 and exert a large stirring action.

Further, since the pin 54 and the guide cylinder 53 are integrally moved up and down, the pin 54 is agitated.
5 is a component 55 which is always located above the pin 54, and the component 55 which is located above the component receiving port 52 of the guide cylinder 53 is not agitated by the pin 54.

It is an object of claims 1 and 2 to provide a component supply device having a large agitation action of components in the hopper, particularly components located above the component receiving port of the guide cylinder.

Embodiment 1 FIGS. 3 to 7 show the present embodiment, FIG. 3 is a longitudinal sectional view, and FIGS. 4 to 7 are process drawings. An outer diameter is held in a hole provided on the upper surface of the box-shaped main body 7, and the hopper 1 is provided. A highly elastic rubber 11 having a through hole 3 in the center is attached to the bottom surface of the hopper 1 to form the bottom surface of the hopper 1. The push-up rod 4 inserted into the through hole 3 has a transfer hole 5 having a shape corresponding to the component 2 on the upper end surface,
A ring-shaped groove 12 similar to the shape (width, diameter) of the through hole 3 is provided on the outer periphery thereof.

The push-up bar 4 has a through hole 3 made of rubber.
The groove 12 is fitted into the through hole 3 and fixed to the rubber 11 by utilizing the expansion and contraction of. The parts 2 are stored inside the hopper 1 in which the through hole 3 is closed by the push-up bar 4. On the other hand, the lower end of the push-up rod 4 is connected via a cylinder 14 attached to the main body 7 and a joint 13, and can be moved up and down in conjunction with the movement of the cylinder 14.

The stroke of the cylinder 14 is the transfer hole 5
The upper limit is the position above the component pool 10 (component removal position), and the lower limit is the position where the bottom of the component pool 10 forms a funnel shape. Sensors 15a and 15b are attached to the cylinder 14. Sensor 15a,
The sensor 15a has a sensor 15a when the transfer hole 5 of the push-up rod 4 is located above in the component reservoir 10 and a sensor 15b when the transfer hole 5 of the push-up rod 4 is located below in the component reservoir 10. Each is installed to detect
The push-up bar 4 is set to repeatedly move up and down between the sensor 15a and the sensor 15b.

The above setting is performed by connecting a control device (not shown) such as a sequencer to the cylinder 14 and the sensors 15a and 15b via the tube 16. On the other hand, the vertical stroke of the push-up bar 4 depending on the positions of the sensors 15a and 15b is arbitrarily set depending on the shape of the component 2.

In the apparatus having the above structure, a control device (not shown) such as a sequencer is activated by a start switch (not shown) or an operation start command such as an external signal, and the cylinder 14 starts to descend (see FIG. 4). ). Before the operation is started, the push-up bar 4 having the transfer hole 5 arranged at the upper limit position above the component reservoir 10 is lowered to the lower limit position via the joint 13. At the same time, the center of the rubber 11 forming the bottom of the hopper 1 is pulled down by fixing the through hole 3 and the groove 12, and the rubber 11 changes into a funnel shape. The funnel-shaped rubber 11 allows the parts 2 to be concentrated in the central transfer hole 5 (see FIG. 5).

By repeatedly moving the push-up bar 4 up and down with a stroke set by the sensors 15a and 15b a preset number of times, the rubber 11 swings, and the component 2 in the component reservoir 10 is agitated and transferred. It is transferred to hole 5. After the vertical movement is completed, the feed-in hole 5 of the push-up rod 4 is elevated to the upper limit position above the component pool 10 and all the operations are completed (see FIGS. 6 and 7). The part 2 set in the transfer hole 5 is supplied to the next step by a supply means such as a robot.

According to this embodiment, it is possible to increase the transfer rate by agitating the parts in the hopper without the need for a drive mechanism other than the vertical movement of the push-up rod. Further, since the parts can be largely stirred in the vertical direction, it is particularly effective when supplying long parts.

In the apparatus having the above structure, a control device (not shown) such as a sequencer is activated by a start switch (not shown) or an operation start command such as an external signal, and the cylinder 14 starts to descend (see FIG. 9). ). The push-up bar 4, which was arranged so that the transfer hole 5 was located above the component reservoir 10 before the operation was started, is lowered via the joint 13. At the same time, the motor 25 is operated to transmit the rotation of the motor 25 via the pulley 24, the belt 26, and the pulley 23, thereby rotating the rotary cylinder 21 having the protrusion 28 at the upper end (see FIG. 10).

The push-up rod 4 moves up and down several times between the upper limit position and the lower limit position by the sensors 15a and 15b, and the protrusion 28 rotates, whereby the component 2 in the component reservoir 10 is agitated, and the component is inserted into the transfer hole 5. 2 is transferred (see FIGS. 11 and 12). After the vertical movement is completed, the rotation of the motor 25 is stopped, the push-up bar 4 is lifted to the upper limit position located above the component reservoir 10, and all the operations are stopped.

According to this embodiment, the transfer rate can be increased by constantly stirring above the transfer hole where the parts are present.
