On the other side, the chute is pivoted so that it can be freely switched between a gently inclined parts receiving position and a steeply inclined parts inputting position, and on the other side of the parts inputting opening, there is a part of the chute in the parts loading path in the parts receiving position. A cover that enters and closes the component input port is provided, and an interlocking arm that switches the chute to the component input posture in conjunction with the opening of the cover is provided, as well as a driving means that drives the cover and the chute in conjunction with each other. There are characteristics.

[Effect]

According to the above characteristic configuration, by closing the component input port of the soundproof case with a cover, sound leakage from the component input port is suppressed, and in conjunction with the closing operation of the cover, the chute switches to the component receiving position. It will be done.

Then, in conjunction with the opening of the cover, the chute is switched to a steeply inclined parts loading position, and the required amount of parts stored in the chute is transferred to the parts feeding machine inside the soundproof case until the cover is opened. Injected.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

Figures 1 and 2 show parts supply equipment. In the figures, 1 is a vibrating parts supply machine that supplies various parts to the next process (conveyor in this example) 2 in desired postures; The entire area is surrounded by a soundproof case 3.

Reference numeral 4 indicates a component take-out port provided on the side surface of the soundproof case 3, and 5 indicates a component input port provided in the upper surface member 3a of the soundproof case 3. The component input port 5 is equipped with a component input device 6, the details of which will be described later. is provided.

Reference numeral 7 is a stock part for parts to be carried in by a lift or the like, and 8 is a loader for supplying the parts stored in the stock part 7 to the parts loading device 6, which slides a rod 10 equipped with an electromagnetic magnet 9 at the lower end. A sensor 12 is provided on the frame 11 so as to be movable up and down, and is movable in synchronization with the magnet 9. The sensor 12 detects whether a component is magnetically attracted to the magnet 9.

Next, the specific structure of the parts feeding device 6 will be explained. As shown in FIGS. 3 to 5, this device has a shaft 14 on both sides of the drawn portion of the chute 13 formed in the shape of a pre-drawn shape. In addition to setting up
This support shaft 14 is supported by bearings 15 provided on both sides of one side of the component input port 5, and the chute 1
3 can be freely switched between a gently inclined component receiving position X (see Figure 4) and a steeply inclined parts loading position Y (see Figure 5). A horizontal shaft 16 parallel to the axis is supported by bearings 17 provided on both sides of the other side of the component input port 5, and the chute 13 is in the component receiving position X.
, when the part 18a enters the component input path P of the chute 13, the part 18a enters the component input port 5.
A cover 18 for closing the horizontal shaft 16 is attached to brackets 19 connected to both ends of the horizontal shaft 16.

Then, the upper side of the cover 18 and the chute 1
An arm 20 is pivotally connected to the lower part of the free end of the horizontal shaft 16, and a driving means 22 such as an air cylinder is connected to one end of the horizontal shaft 16 via a lever 21.

Note that the upper surface member 3 supporting the bearings 15 and 17
A, the chute 13, the cover 18, and the arm 20 constitute an equilateral quadruple link mechanism that moves the arm 20 approximately in parallel. In order to increase the rotation angle of the chute 13 relative to the angle, the quadruple link mechanism with the four members described above may be configured to have scalene sides.

Further, a cushioning rubber 23 is provided on the cover portion 18a of the chute 13 that enters the component input path P.

According to the above configuration, the vibrating component feeder 1
By closing the cover 18 while the parts feeder 1 is being driven, leakage of vibration noise emitted from the parts feeder 1 from the parts input port 5 is suppressed.

Then, by opening the cover 18,
In conjunction with this, the chute 13 is switched to the component loading position Y, and the components stored in the chute 13 are loaded into the component feeder 1 until the cover 18 is opened.

The above-mentioned component supply control is performed, for example, as follows.

That is, while the cover 18 is closed to prevent sound leakage and the component feeder 1 is being driven, the loader 8 is reciprocated between the stock section 7 and the chute 13, and the loader 8 is moved back and forth to the component receiving position X. The required amount of parts is stored in the part input route P of the chute 13 located at the location. Whether or not the loader 8 has reliably supplied parts to the chute 13 each time is checked by the sensor 12 each time.

When a predetermined amount of components are taken out from the component feeder 1 onto the conveyor 2 in a desired posture, the drive of the component feeder 1 is stopped and the cover 1 is stopped.
8 is opened, and the chute 13 is switched to the steeply inclined parts loading position Y.

Then, the required amount of parts previously stocked in the chute 13 is fed into the parts supply machine 1 inside the soundproof case 3. Since the required amount of parts is stored in the chute 13 in advance, the parts The required amount of parts can be fed into the feeder 1 in a short time and efficiently.

Next, the cover 18 is closed after a predetermined period of time has elapsed under control of a timer or the like, and the parts supply is stopped by a command from a blockage detection sensor for the cover 18 provided as necessary or by human control. The machine 1 is driven, and the required amount of parts can be inputted efficiently in a short time, so the driving stop time of the parts feeder 1 is shortened, and the vibrating parts feeder 1 is highly efficient. It will be put into operation.

Note that the component ejection port 4 provided in the soundproof case 3 is small in shape and does not leak sound to the extent that it degrades the working environment. For example, a band-shaped rubber sag may be provided to achieve soundproofing.

[Effect of idea]

As explained above, according to the component feeding device for a vibrating component feeder according to the present invention, by providing a cover over the component input port of the soundproof case, vibration noise emitted from the vibrating component feeder is removed from the case. leakage is effectively suppressed.

Since the chute is equipped with a chute that displays the parts receiving position when the cover is closed and switches to the parts loading position in conjunction with the opening of the cover, it is possible to wait until the next time the cover is opened for parts loading. By storing the required amount of parts in the chute, by opening the cover, you can automatically and efficiently feed the required amount of parts into the parts feeder in a short time. By stopping the drive of the parts feeder only while the cover is opened and closed, the working environment can be prevented from deteriorating, and the operating rate of the vibrating parts feeder can be increased.

Moreover, by adopting a configuration in which the cover and the chute are driven in conjunction with each other, it is possible to reduce the cost of the driving means, and by adding a simple structure as a whole,
As a result, we were able to improve the work environment and increase the operating rate of the parts feeder.
