Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention] (Industrial application field) The present invention provides a method of aligning parts placed in a bowl by vibration.
The present invention relates to an alignment device for supplying, a so-called ball feeder.

(Prior Art) In a semiconductor manufacturing process, a ball feeder is frequently used to supply components. Conventional ball feeders have a transfer track (rail) that is selected according to the shape of the component to be supplied, and the component is put on the rail and supplied by vibration of the bowl.

For example, a plastic part 10 having a shape as shown in FIG. 5A is transported across a rail 11. The conventional ball feeder used in that case is as shown in FIG.
A bowl 17 is fixed to a feeder body 16 incorporating a vibration device by a bowl attaching / detaching screw 17a, and a bowl inner rail 11a is provided on an inner surface of the bowl 17, and a bowl outer rule 11b is continued at an end of the rail 11a. It was of a structure.

However, in the case of a left and right same or symmetrical shape with respect to the rail 11 like the component 10, the left and right are randomly introduced into the rail 11 in the conventional ball feeder,
One of the left and right sides could not be aligned with respect to rail 11.

The component 12 shown in FIG. 5 (b) has a shape in which a connector (receptacle) portion 12a is added to the component 10, and the left and right sides are not symmetrical with respect to the rail 11. Therefore, another bowl utilizing the difference in the shape is used. Then, even with a conventional ball feeder, the transfer can be performed with the left and right aligned. In this case, it is necessary to remove the screw 17a for attaching and detaching the ball feeder shown in FIG. 6, replace the bowl 17 with another bowl adapted to the part, and adjust the seam of the bowl outside rule 11b with respect to another bowl. was there.

As a result, in the conventional ball feeder, there is a problem that the cost of parts is increased, for example, it is necessary to prepare a bowl for each shape of the parts, and it takes time to attach and detach the bowl and adjustment time after attachment and detachment.

(Problems to be Solved by the Invention) An object of the present invention is to provide a ball feeder capable of aligning components that cannot be aligned in view of the shape of components and aligning components having different shapes in the same bowl. It is in.

[Structure of the Invention] (Means for Solving the Problems) In the aligning apparatus of the present invention, first, in order to align a part, if the original shape of the part can be suitably used, it is used. Needless to say, a component having a projection dedicated to alignment in addition to the original shape of the component is used.

That is, the aligning device of the present invention is an aligning device that aligns and supplies a component put into a bowl by vibration, and guides a track for transferring the component and a projection dedicated to alignment provided in addition to the original shape of the component. Guide means for aligning and introducing the protrusions into the track, and removing means for removing the protrusion after the parts are aligned.

(Operation) Since the projection dedicated to alignment can be provided at a position suitable for alignment regardless of the original shape of the component, it is possible to align components that cannot be aligned according to the original shape. Even when components are flowed, if a projection dedicated to alignment is provided in common at a predetermined position, the bowl can be aligned without replacing the bowl regardless of the component shape. After the alignment, a means for removing a projection dedicated for alignment that is not necessary as a part is provided, so that the part is a novel ball feeder that can be used without any trouble after the next step.

(Examples) Hereinafter, the present invention will be specifically described with reference to the drawings showing examples.

The part used first in this embodiment is the plastic case 1 shown in FIG. 2 (a), in which a projection 1a dedicated to alignment is added to the part 10 in FIG. 5 (a). The projection is formed in advance integrally with the case.

FIG. 1 is a perspective view showing a ball feeder of this embodiment. In FIG. 1, reference numeral 16 denotes a feeder body incorporating a vibration device (same as a conventional feeder), 7 denotes a bowl, 7a denotes a track in the bowl corresponding to the cut shape of the case 1, and 8 denotes a feed end of the track 7a in the bowl. In order to guide the protrusion to one side of the track, a guide rod (height from the bowl surface of the guide rod, which is a height h from the bowl surface, which hinders the progress of the protrusion on the other side of the track, is shown in FIG.
7b is an outer bowl track connected to the end of the inner bowl track 7a, and 9 is a projection removing device provided in the middle of the outer bowl track 7b. Projection removal device 9
As shown in the partial enlarged view of FIG. 3, the case holding jig 9a, the holding drive cylinder 9b, the cutter jig
9c, a cutter driving cylinder 9d.

Next, the operation of the ball feeder of this embodiment will be described with reference to FIG. 1 and FIG. The case 1 having the above-described protrusion is put into the bowl 7. Feeder body 16
The case 1 moves toward the leading end of the in-bowl track 7a due to the vibration. The case in which the protrusion comes to the right side toward the in-bowl track 7a by the guide rod 8 at the introduction end cannot move, and only the case in which the protrusion comes to the left side is aligned and introduced into the in-bowl track 7a. When the case 1 has moved to the end of the in-bowl orbit 7a, it moves to the out-of-bowl orbit 7b and reaches the protrusion removing device 9 when the presser driving cylinder
The case holding jig 9a fixes the case 1 by 9b, and the cutter driving cylinder 9d operates to move the cutter jig 9c forward to remove the protrusion 1a, and then the holding driving and cutter driving cylinders 9b and 9d are moved. When the fixing is released, the case 1 is supplied to the next process from the outer bowl track 7b in the original shape from which unnecessary projections have been removed.

FIGS. 4 (a) to 4 (c) show three types of cases 2, 3, and 4 having different shapes from the case 1. FIG. They have projections 2a, 3a, 4a dedicated to alignment, respectively, at the same relational position with respect to the track as the projection 1a in the case 1. Therefore, the guide rod 8 of the feeder can guide the protrusions 2a, 3a, 4a in any case regardless of the shape of the feed rod, and align the guide rod 8 with the track 7a in the bowl. And the projections 2a, 3a,
4a is removed by the cutter jig 9c described above. As such, the ball feeder of FIG. 1 includes the case 1 of FIG. 2 (a), the case 2 of FIG. 4 (a), the case 3 of FIG. 4 (b), and the case of FIG. 4 (c). 4 can be aligned and supplied without replacing the bowl 7.

FIGS. 2 (b) and 2 (c) show a case in which the original shape of the case is the same, but the location of the alignment-specific projections 5b and 6c is different.
5,6 are shown. The bowl for the case 5 is not shown, but a projection for the projection 5b is protruded from the bottom surface of the bowl toward the introduction end of the track in the bowl. On the bottom of the bowl on one side toward the introduction end of the track in the bowl.
By providing guide grooves corresponding to 6c, the cases 5, 6 can be aligned and introduced into the orbit in the bowl. Also, in the case of differently shaped cases 2, 3, and 4 having different connectors shown in FIG. , Or one of the projections 4b, 4c. Then, the case 5, the case 2 with the protrusion changed to 2b, and the protrusion
Case 3 changed to 3b, Case 4 changed to 4b
Can be aligned without exchanging bowls (the same applies to four types of cases having protrusions 6c, 2c, 3c, and 4c at the same location).

The differently shaped cases that can be aligned with one bowl are not limited to those having the same case body but only the difference of the connector shown in FIG. 4, and guide the position of the projection relative to the track and the projection. Naturally, depending on the choice of means, a fairly wide range of cases can be aligned in one bowl.

[Effects of the Invention] According to the alignment apparatus of the present invention, for a component having a projection dedicated to alignment in addition to the original shape of the component, the component is aligned using the projection dedicated to alignment, and then the projection is removed. Since the parts can be formed into their original shapes, a wide range of parts having different shapes can be aligned and supplied using the same bowl, and the productivity can be greatly improved.
