Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a parts feeder bowl that blows up easily entangled parts with compressed air to loosen them and feed them to a feed path having a separating section.

Conventionally, parts that easily get entangled with each other,
For example, in the watch lock 10a (Fig. 1A), the regulating lever 10b (Fig. 1B), etc., the second
As shown in the figure, the tangles were loosened by falling from the feeding path section 2 and sorting section 3 of the bowl main body 1 onto the bottom surface 1a of the bowl. Such bowls have a low disentanglement rate, and tangled parts often remain at the bottom of the bowl. In addition, since the parts are supplied to the sorting section 3 while ascending the spiral feeding path section 2, the bowl bottom section 1
When the number of parts a decreases, the interval between the parts reaching the sorting section increases, and the supply capacity tends to be insufficient.

The present invention has been made to eliminate such drawbacks, and its purpose is to provide a parts feeder bowl that can disentangle easily tangled parts and has sufficient feeding capacity.

The parts feeder bowl according to the present invention has a compressed air blowout hole provided on the outer periphery of the bottom that is continuous with the slope of the inner wall of the bowl body to blow away the stored parts, and a hole that is closed to the slope of the inner wall so as not to be continuous with the bottom surface. a feeding path formed in an annular shape for sorting the blown parts; and a feeding path attached to the upper surface of the outer circumferential side of the bowl main body and formed in a net shape toward the center so as to cover the upper part of the compressed air blowout hole. and a movable separation section that is formed in the same shape as the feed path and has a groove that is disposed on a part of the slope of the inner wall and holds the component.

An embodiment according to the present invention will be described with reference to FIG.

Reference numeral 7 denotes a bowl main body, and a compressed air jetting hole 4 is provided on the outer peripheral side of the bottom portion 7a. A feeding path 8 for the component 10 is provided on the inner wall slope 7b of the bowl main body 7, but the feeding path 2 of the conventional bowl main body 1 is not connected to the bottom 1.
a, the feeding path 8 of the bowl main body 7 of the present invention directly connects to the bottom 7.
Not connected to a. Furthermore, the feed path 8 is the part 10
It is formed in a closed annular shape so that it circulates and comes to the separating section 9. In addition, the center of the upper surface 7d of the outer peripheral side of the bowl body 7 is placed above the compressed air jet hole 4 provided in the bottom 7a of the bowl body 7 so as to cover the compressed air jet hole 4 so as to prevent the blown up parts 10 from scattering. A receiving plate 5 formed in a net shape and protruding toward is provided.

In such a configuration, the operation is explained as follows.
Parts 10 that are easy to get entangled, such as a watch bolt and a regulating lever, are supplied to the bottom 7a of a bowl main body 7.
The bowl main body 7 is connected to a vibrating body (not shown) and continues to feed the parts 10. Compressed air is intermittently sent from the compressed air blowout hole 4 to blow up the parts above the hole. The parts 10 that have been blown up hit a net-like receiving plate 5 that projects centrally from the upper surface 7d of the outer circumferential side of the bowl main body 7, and most of the entangled parts are loosened and can be placed on the feeding path 8. Further, the parts 10 on the feed path 8 circulate in the direction of the arrow 6 on the feed path, are separated by the separating section 9, and are assembled into an assembly device such as a transport (not shown). As shown in FIG.
1, other parts pass over the separating section 9, go around the feeding path 8, and are supplied onto the separating section 9 again. For the parts that have entered the groove 11, the separation part 9 moves intermittently,
At the moved position 12, parts are supplied one by one to the assembly device.

As explained above, according to the present invention, parts at the bottom of the bowl main body are supplied to the feeding path by blowing compressed air onto the upper net-like receiving plate, so that parts entangled with each other can be easily loosened. However, since the backing plate is formed in a mesh shape, the compressed air that blows up the parts is discharged upward through the mesh, so that the parts can be reliably supplied to the feeding path without blowing back the compressed air. In addition, once the parts are fed into the feed path, they are circulated through the closed annular feed path that is not continuous with the bottom, so they will not fall back to the bottom of the bowl due to overflow. ,
Even if the number of parts at the bottom of the bowl decreases, parts are always supplied to the separating section in the feed path, and a sufficient supply capacity to the built-in device can be ensured.

Although the present invention has been explained using the separating section shown in FIG. 4, it is not limited to this separating section, and various separating sections can be used.
