Description

[Detailed Description of the Invention] This invention relates to a parts supply device having a function of dividing parts into a plurality of parts.

1 and 2 are vertical cross-sectional views showing a conventional device of this type, respectively. In the figures, 1 is a base having a component supply hole 2 and an air supply hole 3, and 4 is a base 1 having a component supply hole 2 and an air supply hole 3.
The slide plate 5 is installed under the slide plate 4.
6a to 6d are hose joints attached to the base 1 and the slide plate 4,
7a to 7d are hoses attached to hose joints 6a to 6d.

The component supply hole 2 is connected to the hose 7b via the hose joint 6b, and at the switching position of the slide plate 4,
Hoses 7c and 7 are connected via hose fittings 6c and 6d, respectively.
It is designed to connect to d.

In addition, the air supply hole 3 is connected to the hose 7 via the hose joint 6a.
1 of the slide plate 4 shown in FIG.
In the two switching positions, one flow path is connected to the hose fitting 6d and the hose 7d via the component supply hole 2, and the other flow path is connected to the hose 7c via the hose fitting 6c. .

Next, the operation will be explained.

First, in the state shown in Figure 1, the feeder section of the screw feeding device (
hose 7b connected between the base 1 (not shown) and the base 1.
The components on standby are fed into the hose 7d using compressed air at a pressure P1 over a certain period of time.

After this, the slide plate 4 is moved to the second position by the air cylinder 5.
Slide to the state shown in the figure.

In this state, the parts waiting in the hose 7b are fed into the hose 7c in the same manner as above.

After parts are supplied to the hoses 7c and 7d, the slide plate 4 returns to the state shown in FIG.

Next, when air is fed into the air supply hole 3 at a pressure P2 through the hose 7a, the parts in the hoses 7c and 7d are simultaneously fed to the object to be fed.

Since the conventional parts supply device is configured as described above, when air at pressure P2 is supplied to the air supply hole 3,
At the confluence of the air supply hole 3 and the component supply hole 2, negative pressure may occur in the component supply hole 2 on the feeder side, and components waiting in the feeder side hose 7b may be sucked into the component supply hole 2. There was a drawback that a predetermined number of parts were not supplied to the supplied object.

This invention was made in order to eliminate the drawbacks of the conventional ones as described above.
By providing a shutter mechanism in the parts supply path from the part supply hole 2 to the confluence of the air supply hole 3, waiting parts are prevented from flowing into the feeder section side hose 7b.
It is an object of the present invention to provide a parts supply device that can supply a predetermined number of parts to an object to be supplied.

An embodiment of this invention will be described below with reference to the drawings.

Figure 3 is a perspective view, Figures 4 and 5 are A-A, respectively.
It is a sectional view, and the same reference numerals as in FIGS. 1 and 2 indicate the same or corresponding parts.

3 to 5, 8 is a guide attached to the base 1, and a hole 8a provided in the guide 8 is inserted into the base 1.
It is set so that it is in the same position as the component supply hole 2 of.

9 is a shutter that slides over the component supply hole 2 between the base 1 and the guide 8;
and a hole 9a matching the hole 8a.

10 is an air cylinder for sliding the shutter 9 attached to the guide 8.

The other structures are the same as those in FIGS. 1 and 2.

Next, the operation will be explained.

First, in the state shown in Fig. 4, the feeder section supplies the
When parts waiting in the hose 7b are fed under pressure P□ into the parts supply hole 2 in the base 1, the hole 9a provided in the shutter 9 and the hole 8a provided in the guide 8 are It is located at the same location as the component supply hole 2 of No. 1, and components are smoothly fed through this hole.

Then, as in the case of FIGS. 1 and 2, by moving the slide plate 4, the parts sent to the hoses 7c and 7d, respectively, are force-fed to the object by the air at the pressure P2 from the air supply hole 3. Then, in synchronization with the air supply at pressure P2, the shutter 9 is moved by the air cylinder 10 as shown in FIG. 5, thereby blocking the conduit of the hose 7b and the component supply hole 2 provided in the base 1.

As a result, even if negative pressure is generated in the component supply hole 2, the hose 7b
No parts will be sucked in.

In the above embodiment, the shutter 9 is provided between the base 1 and the hose joint 6b, but the shutter 9 is provided between the parts waiting in the port 7b and the confluence of the parts supply hole 2 and the air supply hole 3. It can be placed anywhere.

Further, the shutter mechanism may be any mechanism capable of blocking the component supply path, and is not limited to the one in the embodiment.

The parts to be supplied in this invention are not particularly limited, and any parts can be supplied.

As described above, according to this invention, the hose 7c.

When the parts inside 7d are fed under pressure, the parts supply path is blocked, which prevents the parts from being sucked into the hose 7d and from flowing into the hose 7d due to the negative pressure inside the hose 7b caused by the air supply P2. On the other hand, there is an effect that a predetermined number of parts can be supplied accurately.
