Abstract

PURPOSE:To provide a smooth vibrating feed by a vibrating bowl feeder without any jamming of parts by aligning the orientation of parts in one direction at its outlet to feed the parts to a linear feeder. CONSTITUTION:A vibrating bowl feeder 1 is provided with a vibrating bowl 2, in which a feed track 3 is formed. The electronic parts stored in the vibrating bowl 2, for example, tab terminals 4 can be vibrating-fed along the feed track 3. Each of the tab terminals 4 has a head 5 and a lead wire 6, which is connected to the head 5 by welding. At the outlet end of the feed track 3, a clearance 9 small enough for the lead wire 6 to penetrate through is made to cantilever-support a flexible guide bar 8 with a supporting block 10 provided parallel. An intermediate guide 11 is installed beneath the guide bar 8 and an engaging rod 12 is set on the lower side near the free end of the guide bar 8. The lead wire 6 of the tab terminal 4 is fitted to the stopping rod 12 to feed the head 5 ahead of the lead wire.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a device for correcting the posture of parts in a vibrating bowl feeder, and in particular, the present invention relates to a device for correcting the posture of parts in a vibrating bowl feeder, and in particular corrects the posture of parts that are randomly vibrated and transported from the vibrating bowl feeder so that the head leads. This invention relates to a posture correction device for parts that can be corrected and sent downstream.

[Conventional technology]

2. Description of the Related Art Vibratory feeders are commonly used to transport parts, such as electronic parts, stored in a hopper to a place of use. A vibratory bowl feeder is often used as this vibratory feeder, and when it is necessary to transfer the food to a location away from the vibratory bowl feeder, a straight feeder of an appropriate length is placed on the outlet side of the vibratory bowl feeder.

By using a vibrating feeder in this way, electronic components can be transported continuously, but if the electronic component is something with a thin lead wire coming out of the head, such as a tab terminal, it is difficult to transport the electronic component in a straight line. It is easier to carry out various processing in the next process if the parts are transported in an upright position when being fed by a feeder. Therefore, the straight feeder has a drop groove for the lead wire formed along the center of the feeding track, and parts that are sent in a lying position can be brought into an upright position by dropping the lead wire into this drop groove. The part is then transported while maintaining its upright position by supporting the lower surface of the part's head on the support surface of the feeding truck.

[Problem to be solved by the invention]

However, in the past, the head of the component was in front, the lead wire was in front, and the lead wires were fed separately, so when the component was dropped, the lead wires of adjacent components could become entangled, or the lead wires of tab terminals could not be attached properly. There was a problem in that due to the friction of the welded parts of the feeders, parts got stuck in the drop grooves of the straight feeders, causing stagnation and traffic jams.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to solve the above-mentioned problems of the prior art, and to align the orientation of the parts in one direction at the exit of the vibrating bowl feeder and feed them to the straight feeder, so that the parts can be smoothly delivered without becoming jammed. An object of the present invention is to provide a device for changing the posture of components in a vibratory bowl feeder, which enables vibratory transport of components.

[Means to solve the problem]

In order to achieve the above object, the present invention vibrates and transports a component having a lead wire protruding from the lower surface of the head from the inside to the outside along the feed track of a vibrating bowl feeder,
Furthermore, in the apparatus for correcting the posture of parts in a vibratory bowl feeder, in which the parts are vibrated and transported downstream in an upright position by a straight feeder disposed adjacent to the vibratory bowl feeder, two A flexible book guide rod is cantilevered in parallel with a gap large enough for the lead wire to pass through, and a locking rod is installed laterally below near the free end of the flexible guide rod. The present invention is characterized in that the lead wire of the component is hooked on the locking rod, and the head of the component is placed in front of the lead wire so that the component is fed in a recumbent state.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a device for correcting the posture of components in a vibrating bowl feeder according to the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 1 indicates a vibratory bowl feeder;
This vibrating bowl feeder 1 is known per se, and has an inner conical vibrating bowl 2, in which a spiral feeding track 3 extending from the bottom toward the outer periphery is formed. There is. The lower surface of the vibrating bowl 2 is equipped with an electromagnet that generates electromagnetic vibration for transporting parts, a vibrating plate spring that supports the bowl and converts it into vibration for transportation, and a controller. Therefore, when the electromagnet is excited, electronic components such as tab terminals 4 stored in the vibrating bowl 2 can be randomly vibrated and transported along the feeding track 3 in the direction of the arrow while lying down.

Here, the form of the tab terminal 4 will be explained with reference to FIG. 2. It has a head 5 and one lead wire 6 protruding from the lower surface of the head 5. 5 is welded to the welded portion 7.

At the exit end of the feed truck 3, there is a 2
Thin wire-shaped flexible guide rods 8, 8 are arranged in parallel to a support block 10 with a gap 9 large enough for the lead wire 6 to pass through.
Cantilevered through. It is desirable that the tip of the guide rod 8 is curved downward in an arc shape. Immediately below the free end of this guide rod 8 is a nearly horizontal conveyance path 11.
An intermediate guide 11 having a diameter of 1.a is installed, and this intermediate guide 11 is integrally fixed to the vibrating bowl 2 and is subjected to vibration action. In addition, the guide rod 8
A locking rod 12 having a substantially doglegged planar shape is provided below near the free end of the vibrating bowl so as to project laterally from the vibrating bowl. The height of the locking rod 12 is preferably such that the lead wire 6 of the tab terminal 4 suspended by the guide rod 8 is caught.

Further, a linear feeder 14 is provided adjacent to the intermediate guide 11. This linear feeder 14 has a long feeder main body 15, and this feeder main body 1
A drop groove 16 is formed in the center portion of the upper surface of 5 over the entire length. Both sides of the opening of this drop groove 16 are cut out in a character shape to form a feeding path 17, and below these,
Support rails 18, 19 having a circular cross section are fixed in parallel, leaving a gap 20 between them. The size of this gap 20 is preferably set so that the head of the tab terminal 4 is supported by the support rail and the lead wire 6 is suspended through the gap 20.

Further, it is preferable that each of the support rails 18, 19 is divided into three parts in total length, and only the four upstream ends are fixed, and the downstream ends are left free.

Since the present invention is configured in this way, the vibrating bowl 2
The tab terminal 4 sent randomly from the guide rods 8, 8
Then, the lead wire 6 is dropped into the gap 9 and is fed while taking a standing position. On the way, the lead wire 6 gets caught on the locking rod 12 and the head 5 is turned down onto the conveyance path surface 11a of the intermediate guide 11.
It falls over and is sent to the straight feeder 14 with the head 5 in the lead.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, the parts coming out from the exit of the feed truck of the vibrating bowl feeder are sent while being suspended along the guide rod, and the lead wire is attached to the locking rod on the way. If it gets caught, it will fall onto the conveyance path of the intermediate guide with the head in front, and it will be led to the straight feeder with the head always in front, so the lead wires of adjacent tab terminals will become entangled and become jammed at the straight feeder. It was sent smoothly without any problems.
