Abstract

PURPOSE:To prevent the generation of a trouble due to a part of different kind enabling an electronic part, left existing in a recess and a groove of a vibrative bowl, to be easily discovered from the outside by forming the vibrative bowl by a transparent material so as to enable the part to be seen through from the outside. CONSTITUTION:When a vibrative bowl feeder 1 in a part supplier A is driven and given vibration, electronic parts 4 in the vibrative bowl are conveyed along a feed track 3 from the inner toward the outer, reaching a supply station 5. Next, when a vibrative bowl feeder 8 is simultaneously driven, vibration of a table 9 is propagated to a straightening feed ring 6, and it continuously rotates in the clockwise direction. And from the feed station 5, many of the electronic parts 4 are supplied in a random condition naturally dropping toward pocket grooves 7, 7... of the straightening feed rings 6. Here because the vibrative bowl 2 is formed by a transparent material, the electronic parts, intruded into a hollow, recess and a pocket groove of the vibrative bowl, can be easily seen through from the outside.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a vibrating bowl feeder device, and in particular, the present invention relates to a vibrating bowl feeder device, in which the vibrating bowl is made of a transparent material, and the electronics remaining in the recesses, pocket grooves, and recesses in the vibrating bowl are removed. The present invention relates to a vibrating bowl feeder that allows parts to be easily discovered by looking through them from the outside.

[Conventional technology]

Generally, vibrating bowl feeders are widely used when feeding electronic components such as capacitors stored in a hopper to a place of use. Electronic components such as capacitors stored in the vibrating bowl are sent out from the inside to the outside by the vibration action along a spiral trajectory. The vibrating bowl of conventional vibrating bowl feeder equipment is cast with cast iron or made of steel plate, and the vibrating bowl has a passageway for returning electronic components to the middle of a spiral track or the bottom of the vibrating bowl, and a large number of passages inside the vibrating bowl. Many hollows and depressions are formed.

[Problem to be solved by the invention]

These vibrating bowl feeders usually handle multiple types of electronic components using the same vibrating bowl, so after finishing feeding a specific type of electronic component, the inside of the vibrating bowl should be thoroughly cleaned and the previous electronic component must be thoroughly cleaned. The components must be cleaned out and carefully checked for any remaining electronic components from the previous one. However, in reality, electronic components often remain in the recesses and recesses of the vibrating bowl, and as a result,
Next, different types of electronic components were fed together with the electronic components loaded in the vibrating bowl, causing trouble during assembly work.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a vibrating bowl feeder device that allows electronic components remaining in a vibrating bowl to be easily found from the outside.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a vibration generator that applies transportable vibrations in the circumferential direction to the vibration bowl in the lower part of the vibration bowl, which is provided with a spiral trajectory running from the inside to the outside. The vibrating bowl feeder device to which the device is attached is characterized in that the vibrating bowl is made of a transparent material.

[For production]

According to the vibrating bowl feeder device configured as described above, the vibrating bowl made of a transparent material can be seen through from the outside, making it easy to discover hidden electronic components remaining in the recesses and recesses of the vibrating bowl. can do.

〔Example〕

An embodiment of a vibrating bowl feeder according to the present invention will be described below with reference to the drawings.

FIG. 1 shows a plan view of a parts supply system to which the present invention is applied, and this parts supply system includes a parts supply device A.
, a parts sorting device B, and a parts delivery device C.

Component supply device A is a device that supplies electronic components such as capacitors stored in advance to component sorting device B using a vibrating bowl feeder, and component sorting device B feeds the supplied electronic components at regular intervals. This device aligns the parts and sends them out to the next part delivery device C.

The above-mentioned component feeding device A is composed of a vibrating bowl feeder 1, which is known per se, and has a spiral-shaped vibrating bowl 2, inside which is a spiral feeding track. 3 is formed. Further, a recess A, a return passage B, etc. are formed in the middle of the feed track 3 of the vibrating bowl 2. The bottom of the vibrating bowl 2 is equipped with an electromagnet that generates vibration for vibrating the electronic components, a vibrating plate spring that supports the bowl and converting it into vibration for transport, and a controller.

Therefore, when the electromagnet is energized, the electronic components 4 stored in the vibrating bowl 2 can be delivered from the inside to the outside along the feeding track 3. According to the invention, the vibrating bowl 2 is made of transparent material. Suitable examples of such materials include acrylic resin, polycarbonate resin, hard vinyl chloride resin, urea resin, styrene resin, methacrylic acid methyl ester, polyethylene ABS resin, and polypropylene resin. Moreover, it can be made of glass instead of these resins.

A supply station 5 is provided at the exit end of the feed truck 3, and a parts sorting device B is connected to the supply station 5.
The electronic components 4 can be dropped and supplied in a random manner.

The parts sorting device B is equipped with a sorting ring 6, and on the outer circumference of the sorting ring 6, a plurality of pocket grooves 7, 7, . . . 7 are formed at a constant pitch. There is. The size of this pocket groove 7 is set to be large enough to accommodate an electronic component, and when the electronic component 4 is a capacitor, for example, the first
As shown in the figure, insert the main body of the capacitor into the pocket groove 7.
The lead wires are housed inside and the lead wires protrude outward in the radial direction.

The above-mentioned sending ring 6 is installed on a table 9 of the vibrating bowl feeder 8, and this table 9 is made of aluminum alloy.

The above-mentioned sending ring 6 is given a synchronous driving force in the clockwise direction in the figure by the vibrating bowl feeder 8. To this end, the vibrating bowl feeder 8 includes an electromagnet that generates vibration and a diaphragm spring that converts the vibration into clockwise transportable vibration with respect to the table 9.

When the electromagnet is excited, the sending ring 6 rotates clockwise due to vibration, and the rotation speed can be controlled by adjusting the amplitude.

On the other hand, the parts feeding device C is constituted by a linear feeder 10, and this linear feeder 10 has a feeding track 1.
1, and a single guide groove 12 is formed in the center along the elongated direction.

Since the present invention is configured as described above, when the vibrating bowl feeder 1 of the component supply device A is driven by vibration, the electronic components 4 in the vibrating bowl are moved from the inside to the outside along the feeding track 3. and reaches the supply station 5. When the vibrating bowl feeder 8 is driven at the same time, the vibration of the table 9 is propagated to the shuffling ring 6, and the shuffling ring 6 rotates continuously in the clockwise direction. Then, a large number of electronic components 4 are randomly supplied from the feeding station 5 by naturally falling toward the pocket grooves 7, 7, . . . , 7 of the shuffling ring 6.

According to the present invention, since the vibrating bowl 2 is made of a transparent material, it is possible to easily see through the electronic components that have entered the recesses, recesses, and pocket grooves of the vibrating bowl from the outside.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, since the vibrating bowl is made of a transparent material and can be seen from the outside, electronic components remaining in the recesses and grooves of the vibrating bowl can be removed from the outside. It can be easily discovered, and troubles caused by sending dissimilar parts can be prevented.
