Abstract

PURPOSE:To provide an element true-up conveyor of high applicability, by supporting an annular member slidably on the outermost circumferential part of the inside of a bowl-shaped element reception container having a spiral track on the inside and by causing the member to hold a block on which only an element in proper posture can be engaged. CONSTITUTION:When a vibrating driver is put in operation to give a bowl 18 a torsional vibration, elements 10 in the bowl are sequentially moved on a spiral track 27 and brought onto the annular member 31 of an element true-up unit 30 through a guide 29. Each element 10 in a prescribed posture has its bottom recess 11 fitted with the engaging member 16 of an engaging block 12 and is then conveyed to an element supply port 18a by the rotation of the annular member 31 along an annular track 32. On the other hand, each element 10 not in the prescribed position fails to be fitted with the engaging member 16, so that the element gravitates out into a trough 34. The elements 10 conveyed to the supply port 18a is removed from the block 12 by a wiper plate 35 and sent out to a supply groove 19.

A vibrating parts feeder is generally called a parts feeder and is widely used for sorting and feeding divine parts. ing. Various parts sorting devices have been developed for this sorting, and among these, for example, a parts sorting device as shown in FIG. 1 is known. FIG. 1 is a partial plan view, and it shows that a spiral track is formed on the inside of the bowl-shaped component receiver (1) (hereinafter referred to as a ball), and a spiral track is formed on the innermost outer circumferential portion. An annular member (2) is movably disposed.

A plurality of notches (3) as shown are formed at equal angular intervals on the inner circumferential side of the annular member (2). When the ball (1) is subjected to a known torsional vibration force, the annular member (2)
As shown by the arrow Iri, the ball (an annular track (5) integrally formed on the outermost part of IJ) is rotated.

From the inner helical track of the ball (1) to the annular member (
A part (4) is fed into the notch (3) of 2), but the part (4) engaged in alignment with the notch (3) is removed along with its 1-turn l;v of the annular member (2). The part is transferred and discharged to the outside from the part supply port, but the notch (6) formed in the annular track (5) causes the part (4) engaged in a non-aligned state with the notch (3) to pass through a narrow passage. It fell inward at the first track (5) and was eliminated.

In the parts sorting device as described above, whenever the shape of the parts to be sorted changes, an annular cutout having a notch corresponding to the shape must be cut each time. In other words, there is no versatility in the ring part play.

Further, forming a plurality of notches t corresponding to the shape of the part at equal angular intervals on one surface of the inner periphery 91' of the annular portion requires considerable effort.

The present invention has been made in view of the above-mentioned problems, and provides a parts sorting device for an am parts feeder that can provide versatility to an annular member and can easily handle parts of various shapes. The purpose is to do two things. According to the present invention, the present invention provides a vibrating parts feeder in which a dog-shaped parts receiver is provided with a spiral track formed therein, and the parts on the track are transferred by giving a torsional vibration to the part receiver. , an annular member is arranged to be slidable in the circumferential direction on the innermost outer circumferential portion of the component receiver, and desired grooves are inserted into a plurality of notches formed at equal angular intervals on the inner circumferential side of the annular member. All of the blocks for maintaining components in the normal posture that can be engaged with the components in the posture are held, and the component sound is guided from the spiral track of the component receiver onto the annular member, and the block for maintaining the components in the normal posture is engaged. The parts are transferred as they are with the rotation of the annular member relative to the part receiver, are separated from the correct posture part holding block at the part supply port of the part receiver, and are supplied to the outside. A vibrating component characterized in that the components that are not engaged with the posture component holding block are removed inwardly from the annular member while the annular member is rotating relative to the one-item receiver. This is accomplished by a parts sorting device in the feeder.

The details of the present invention will be explained below based on the illustrated embodiments.

The torsional vibration drive section is formed as described above, the entire drive section is covered with a cover (2!!), and the entire feeder αη is supported on the base by the anti-corrosion rubber (26).

As shown in Fig. 4, a spiral track Q is formed inside the ball (toward), and a guide for guiding the parts QO to the parts sorting device is formed integrally with the surrounding wall 5 (281). The parts sorting device □□□ mainly uses balls (
A friend annular member (3υ) arranged slidably in the circumferential direction on the innermost outermost part of the annular member Oυ, and a plurality of notches 0 moats formed at equal angular intervals on the inner circumferential side of this annular member Oυ. It consists of a positive position component engagement block (6) received in the.

As shown in FIG. The normal 7-position component engaging river block σ3 is an annular track (an annular protrusion (32a) formed on the inner circumference of 3'IJ).
The ball is prevented from falling inward, and is placed on the slope part (32C) of the annular track (3 circles).The slope part (32C) of the annular track 02 is connected to the parts supply port (18a) of the ball A line The angle of inclination gradually decreases as it approaches the component supply port (18a), and becomes horizontal near the component supply port (18a) as shown in FIG. ), it gradually approaches the inclination angle shown in FIG.
There is a valley bottom 6 that slopes inwardly and downwardly between the peripheral wall (2) and the peripheral wall (2).
A ball is formed, and the fallen part O0 is guided into the spiral track (2n) through an opening (ceramic) formed in the lower part of the peripheral wall part 4.
Near the supply port (18a), a wiper plate 6!19 serving as an engaging part separating means is disposed diagonally across the upper part of the annular member (31).

The embodiment of the present invention is constructed as described above, and its operation will be explained below.

First of all, let me show you a large number of parts c1 when starting rigid manufacturing.
1 is inserted into the central part of the ball (to), that is, the spiral track (2'r1 part). When the coil <241 is energized, the ball (to) performs a torsional perturbation, and the parts on the spiral track t2D are transferred in various postures and passed through guide C1!91 to the annular member (
It is led up to 3υ. Among these parts 00, as shown in FIG. 5, the recess 4 formed on the bottom of the part αQ guided in the desired attitude is the tip of the retaining piece (a) of the normal attitude part engagement block (b). (16a), and as the annular member 61) rotates in the direction shown by the arrow, parts are supplied.
It is conveyed to the mouth (18a). In addition, the component 01 that is not in the desired posture, for example, the component 0Q that has been guided upside down on the annular member (3) 1, is located at the tip (16a) of the holding piece μs of the block 4 for maintaining the normal posture component, as shown in Fig. PS6. Since it cannot engage with the trough, it falls to the bottom of the valley (31) due to its gravity, passes through the opening (4), and returns to the spiral track (31).
271.

With the rotation of the annular member (3B), the component OQ, which has been transported near the component supply port (18a), advances while still touching the wiper plate (c) as shown in FIG.
51, the concave support is disengaged from the tip (16a) of the retaining piece (T) of the correct posture component retaining block (6). That is, the tip fl (16a) of the retaining piece (4) is pushed downward by the slope of the recess av against the & twisting force of the sub 1 nongular αQ, and as the annular member 61) rotates, the part θQ becomes correct. Attitude component retention block (2) is separated from Rikishima. The part 00 is fed in the same position through the supply trough [11] to the next process (not shown).

FIG. 8 is a partially cutaway perspective view of another part t4G and a corresponding correct posture part holding block (4). In the case of this part t4G, there is a cylindrical recess (41)' on the bottom surface. t
11 (44) formed on the upper surface of the main body (43). If it is difficult, the retaining part (fence) may also be configured to be slidably received within the hole by a spring, similar to block O4 in Fig. 2.

FIG. 9 is a partially cutaway perspective view of another component and a block for maintaining the correct posture component 6 that is attached to it. This component 5Q has a through hole 15B in the center, and the lower end side is increased in diameter to form an annular stepped portion 621.

A retaining portion 151 similar to that of the block shown in FIG. 8 is formed on the upper surface of the main body (54) of the block (531), and can be engaged with the five parts 6I and the annular step portion (52); .

In this case as well, if it is difficult to separate the wiper plate (39), the engaging portion (55) may also be replaced by the block (6) in Figure 2.
Similarly, the structure may be such that it is slidably received in the hole by a spring.

When feeding the parts <10 side shown in FIGS. 8 and 9 in the direction of the arrow in the orientation shown, the corresponding correct posture component holding block (4211531k annular member 01 shown in FIG. 4) It can be fitted into the notch in place of the above-mentioned normal posture component engagement block (6). The rest has the same configuration and operates in the same way as described above.

In the above, the wiper plate 6 is used as the maintenance component separation means.
10 and 11 show this modification. Note that in FIGS. 10 and 11, parts corresponding to those in FIGS. 3 to 7 are designated by the same reference numerals.

In this modification, the part shown in Fig. 8 (a part t whose shape is similar to 4)
[io) is applied, but a cylindrical recess is formed in the bottom of the diameter Ir1, which is also similar to the block for holding parts in the correct position (four in shape, similar to a furnace) in Fig. 8. It is designed to engage with the engagement portion (63) of the normal posture component engagement block (67J).This block (6 is also housed within the notch end of the annular member 01 as described above). A pair of rails (64a) (64b) are formed integrally with the ball near the component supply port of the fourth light, and these rails extend upward toward the component supply port as shown in FIG. The parts (sides) that are engaged with the correct posture parts holding block (6) and transported to the rails (64a) (64b) are received on both sides of the bottom by the rails (64a) (64b). The rails (64a) (64b) are transferred to the upper sound component supply ports by receiving the torsional vibration force of the ball (to).Since the rails (64a) (64b) Lrl are inclined upward, this transfer is At the same time, the part (6o) is separated from the block haze.

Although the embodiments of the present invention have been described above, the present invention is not limited thereto, and various modifications can be made based on the technical idea of the present invention.

For example, in the above embodiments, a wiper plate (39) and a pair of vole (64a) (64b) were used to separate a component in a desired posture from a normal posture component retaining block at the component supply port. Instead of using such a component separation means, it is also possible to use a robot's tip to lift the components upward at the component supply port.

Alternatively, it may be lifted upward by a vacuum suction device.

Furthermore, in the above embodiments, the component has a recess or recess, and the block for maintaining the correct posture component has a retaining portion or a retaining piece as a convex portion, and these concave and convex portions are engaged, but the relationship between the concave and convex portions is It works even the other way around. That is, the convex portion of the component may be engaged with the concave portion of the block for maintaining the component in the normal posture. Alternatively, a component formed by combining a convex part and a recessed part may be engaged with a correspondingly positive posture component engagement amount block formed by combining a convex part and four parts.

As described above, according to the parts sorting device in the vibrating parts feeder of the present invention, a common annular member can be used for sorting and feeding various parts, and each cut of the annular member can be adjusted according to the shape of the part. Since it is only necessary to prepare a block for maintaining parts in the correct position that can be accommodated in the notch, the versatility of the device is high and manufacturing costs can be reduced.
