Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for distributing and supplying works with legs. Further, the present invention relates to a device for adjusting the orientation of a work with legs having two legs of different lengths, and distributing and feeding the work.

[0002]

2. Description of the Related Art When a work is supplied from a torsional vibration part feeder, the processing capacity of the supplied post-process side is low and the capacity of the torsional vibration part feeder may be excessive. In such a case, it is preferable to divide the work into two series from one torsional vibration parts feeder, distribute the work, and supply the work to the subsequent process. However, it is unavoidable for the work that the method of distributing and distributing is not established.
One torsional vibration parts feeder is assigned to the subsequent process of the series. An example of such a work is a capacitor having two lead wires as shown in A of FIG. Among them, the electrolytic capacitors have different lengths of the two lead wires because it is necessary to distinguish the polarities. Even if an attempt is made to distribute this type of capacitor by linear vibration by distributing the lead wire from the slit by suspending the head and suspending the head by the distribution mechanism, entanglement of the lead wires easily occurs, and the capacitor It was difficult to sort for practical use because it could not maintain the vertical posture and fell down. If a method of distributing work pieces with legs such as this capacitor is established, it is possible to supply with one torsional vibration parts feeder for multiple series of post-processes with low processing capacity, and equipment cost can be reduced. Furthermore, if the two legs with different lengths can be aligned and supplied in a distributed manner, conventionally,
Alternatively, since it is possible to omit the provision of the directionality in the subsequent process using the robot, the effect of cost reduction is great in this respect.

Is subjected to linear vibration in the direction of arrow d by the drive unit 51 ′, and transfers the electrolytic capacitor C in the direction of arrow e.

The distributing and feeding apparatus of this embodiment is constructed as described above, and its operation will be described below.

Referring to FIG. 2, torsional vibration parts feeder 1
It is assumed that a large number of electrolytic capacitors C are accommodated in the bowl 11 of No. 0 (shown in a scattered manner in FIG. 2), and the torsional vibration parts feeder 10, the first linear vibration parts feeder 30, the distribution unit 80, It is assumed that all the second linear vibration part feeders 90 are energized and controlled by a process computer (not shown) to be in an operating state according to a time chart.

The electrolytic capacitor C in the bowl 11 is moved to the periphery of the bottom surface 12 by being subjected to torsional vibration, and the track 13
The upper part is brought into contact with the side wall, rises spirally, and is transferred in the direction of arrow a in a recumbent posture. During this time, the lead wire L
The electrolytic capacitor C in which a and Lb are entwined with each other falls into the pocket 18 provided in the track 13 and is returned to the bottom surface 12 of the bowl 11. And, the pocket 1 is only in the single row with the unentangled electrolytic capacitor C lying down.
After passing through the track 13 whose width is narrowed by 8, the next suspension truck 14 is reached.

Referring to FIG. 4, the electrolytic capacitor C falls from the track 13 to the suspension track 14 having an inverted C-shaped cross section, but is pulled toward the center of the suspension track 14 and the lead wires La and Lb are slit 15. To the head H
It takes a suspended posture and starts to be transferred.

Since the slit width of the slit 15 is larger than the distance between the electrolytic capacitor C lead wires La and Lb,
The electrolytic capacitor C is transferred at random in the direction in which the lead wires La and Lb are arranged. Further, although the electrolytic capacitor C is subjected to torsional vibration during this transfer, the lead wires La and Lb made of a magnetic material are attracted to the permanent magnet 16 arranged below the slit 15, so that the suspension posture is large. It does not collapse, and therefore the adjacent electrolytic capacitors C are prevented from entwining the lead wires La and Lb.

After exiting the suspension truck 14, the electrolytic capacitor C is connected to the first transfer path 3 of the first linear vibration parts feeder 30.
1, but the slit 15 of the suspension truck 14
And the slit 35 of the first transfer path 31 is arranged on the same line, and the slit width of the wide slit portion 35a of the slit 35 is the same as the slit width of the slit 15 of the suspension track 14, so the transition thereof is made. There is no hurry.

In the first transfer path 31, referring to FIGS. 5 and 6, one side below the wide slit portion 35a (right side facing the transfer direction) is arranged in parallel with the wide slit portion 35a. The lead wires La and Lb are attracted by the magnet 37, but the guide plate 36 that also serves as a mounting plate of the permanent magnet 37 has a wide slit portion at its edge between the introduction portion 36a and the straight portion 36b. Since it is widened to a position below 35a, also referring to FIG. 8, one of the lead wires La and Lb of the electrolytic capacitor C attracted by the permanent magnet 37 has an obstacle in the shorter lead wire La. However, the longer lead wire Lb is prevented from approaching by the guide plate 36. Therefore, the electrolytic capacitor C, which has been randomly transferred in the directions of the lead wires La and Lb, has a shorter length while the longer lead wire Lb is transferred from the introduction portion 36a of the guide plate 36 into contact with the straight portion 36b. The lead wire La of is directed toward the permanent magnet 37.

Further, when the longer lead wire Lb of the electrolytic capacitor C reaches the protruding portion 36c of the guide plate 36, referring also to FIG. 9, the longer lead wire Lb is protruded portion 36.
The transfer is braked by c, and is slightly inclined from directly below the wide slit portion 35a and tilted. As a result, the shorter lead wire La is also slightly moved away from the permanent magnet 37, but since the magnetic attraction force is inversely proportional to the square of the distance, the attraction force to the shorter lead wire La is greatly reduced and the transfer speed is increased. Is increased. Therefore, as shown in FIG. 5, the electrolytic capacitor C rotates in the protruding portion 36c of the guide plate 36 in the direction indicated by the arrow k, and the shorter lead wire L
The lead wire Lb, which is longer than the lead wire Lb, is left behind. At this point, the slit 35 is a transition portion 35t that narrows the width, and the electrolytic capacitor C is introduced into the narrow slit portion 35b at the downstream portion of the first transfer path 31 with the shorter lead wire La first. .

Since the slit width in the narrow slit portion 35b is smaller than the distance between the lead wires La and Lb, the electrolytic capacitor C does not change its direction during transfer. Also, referring to FIG. 10, the transferred electrolytic capacitor C
The head H is sandwiched by the posture control plates 41 provided on both sides of the narrow slit portion 35b to prevent the head H from leaning to the left and right, and by the permanent magnets 45 provided in the lower portion of the trough 32. When the lead wires La and Lb are sucked, the lead wires La and Lb are transferred in an orderly manner in a vertical posture.

Further, referring to FIGS. 5, 6, 11, and 12, at the downstream end of the first transfer path 31, one end is locked by the locking member 42 and the other end is provided with a twist 43s. Then, the two pairs of upper and lower wire springs 43 sandwiching the electrolytic capacitor C from both sides stop the transfer of the electrolytic capacitor C, and rows are formed in order from the downstream end twist 43s.

The overflow sensor 101 provided at the upstream end of the first transfer path 31 has its light emitting element 101a.
When the light from the light-receiving element 101b is not received by the light-receiving element 101b for a predetermined number of seconds or longer, that is, when the electrolytic capacitor C has a transfer clogging and the head H is in close contact with the light-emitting element 101a, the light is blocked from overflowing. When it is determined that the problem has occurred, the entire device is automatically stopped. In addition, the fall provided at the downstream end of the first transfer path 31
When the light from the light emitting element 102a is continuously received by the light receiving element 102b for a predetermined number of seconds or more, that is, when the head H of the electrolytic capacitor C does not block the transfer, the transfer dead sensor 102 may not transfer or It is determined that the electrolytic capacitor C has fallen, and also when the light reception by the light receiving element 102b is disturbed, it is also determined that the electrolytic capacitor C has fallen and the entire apparatus is automatically stopped. And
In any automatic stop, a pilot lamp (not shown) is turned on to prompt a worker to normalize and restart.

At the downstream end of the first transfer path 31, the electrolytic capacitors C which are stopped by the wire spring 43 and form a row are operated by the distribution stage 60 of the distribution mechanism 80 and the chuck group 70 in cooperation with each other. The second transfer path 91 and the third transfer path 91 'are distributed. First,
The frame main plate 81 located at the front position is moved to the rear position shown in FIG. 13 by the air cylinder 88 for moving the chuck group 70 back and forth. By this movement, referring to FIG. 14 showing the distribution stage 60 and the chuck group 70, the first chuck 71 is sandwiched by the wire springs 43 on both sides of the downstream end of the first transfer path 31 to form a row. 5 6mm

(Hereinafter, in order to distinguish from others, this electrolytic capacitor array nC
Is set to nC ₂ and the subscripts are also attached to other electrolytic capacitor rows nC), and the third chuck 73 is the position where the third chuck 73 is conveyed to the second slit 63 of the distribution stage 60 located at the right position and is present. This is the position to grip the capacitor array nC ₁ . At this time, the second chuck 72 has no electrolytic capacitor array nC to be grasped.

In this rear position, the first chuck 7
The air cylinders 74 of the first chuck 2, the second chuck 72, and the third chuck 73 are actuated to close the opening / closing legs 75, and the head H is sandwiched by the rubber pieces 79 from both sides of the electrolytic capacitor array nC. At this time, the first chuck 71 on the first transfer path 31 inserts the rubber piece 79 between the pair of upper and lower wire springs 43.

Next, the air cylinder 88 for forward and backward movement pushes out the frame main plate 81 to the front position. At this time, the distribution stage 60 is at the right position and the first slit 62 of the distribution stage 60 has the first transfer path. 31 narrow slit portion 35
Since the second slit 63 of the distribution stage 60 is on the same line as the slit 95 'of the third transfer path 91', the first chuck 71 has the narrow slit portion 35b of the first transfer path 31. The lead wires La and Lb of the electrolytic capacitor array nC ₂ at the first slit 62 of the distribution stage 60.
Then, the electrolytic capacitor array nC ₂ in the first transfer path 31 is moved to the first slit 62 of the distribution stage 60 so that the grip is released. At the same time, the third chuck 73 similarly moves the gripped electrolytic capacitor array nC ₁ from the second slit 63 of the distribution stage 60 to the slit 95 ′ of the third transfer path 91 ′ to release the grip. Then, the second chuck 72 moves to the second transfer path 91 while remaining empty. Due to this, the chuck group 70 and the electrolytic capacitor array nC
14 is indicated by the one-dot chain line in FIG. Since the distribution stage 60 is not vibrating, the electrolytic capacitor array nC ₂ moved to the first slit 62 thereof is stationary at the spot, and the electrolytic capacitor array nC ₂ moved to the slit 95 ′ of the third transfer path 91 ′. nC ₁ undergoes linear vibration and is transferred to the downstream side.

Next, the distribution stage 60 is laterally moved to the left by the lateral movement air cylinder 67, the second slit 63 of the distribution stage 60 is aligned with the narrow slit portion 35b of the first transfer path 31, The first slit 62 of the distribution stage 60 is aligned with the slit 95 of the second transfer path 91. During this period, the electrolytic capacitor C is stopped in the wire spring 43 of the first transfer path 31, and the electrolytic capacitor array nC ₃ is formed.

After that, the chuck group 70 is returned to the rear position by the air cylinder 88 for moving back and forth, and the first chuck 71 grips the electrolytic capacitor array nC ₃ in the wire spring 43 of the first transfer path 31, The second chuck 72 is moved to the first slit 62 of the distribution stage 60 by the first chuck 71 and is present in the electrolytic capacitor array n.

Next, the chuck group 70 is pushed out to the front position, and referring to FIG. 15, the first chuck 71 distributes the electrolytic capacitor array nC ₃ to the second slit 63 of the distribution stage 60.
The second chuck 72, and the second chuck 72 moves to the electrolytic capacitor array nC.
After moving ₂ to the slit 95 of the second transfer path 91, the grips are released. The third chuck 73 moves onto the third transfer path 91 ′ without grasping any of them. Then, the electrolytic capacitor array nC ₃ moved to the second slit 63 of the distribution stage 60 stands still on the spot, and the electrolytic capacitor array nC ₂ moved to the slit 95 of the second transfer path 91 receives linear vibration and is downstream. Transferred to the side. During this time, the first transfer path 91
In the wire spring 43, the next row of electrolytic capacitors C starts to form.

Subsequently, the distribution stage 60 is laterally moved to the right position, and the first slit 62 of the distribution stage 60 is moved to the first position.
The narrow slit portion 35b of the transfer path 31 and the second slit 63 of the distribution stage 60 are in the same line as the third transfer path 91 '.
Are aligned on the same line as the slit 95 '. During this time, the next electrolytic capacitor array n is placed in the wire spring 43 of the first transfer path 31.
C ₄ is formed.

As a result of the reciprocating movement of the chuck group 70 in the front-rear direction and the reciprocating movement of the distribution stage 60 in the left-right direction, the electrolytic capacitor array nC on the first transfer passage 31 becomes the second transfer passage 91 and the third transfer passage 91 '. One cycle of distributing and distributing to the chuck is completed. From this state, the chuck group 70 is returned to the rear position and the next cycle starts.

For simplification of the description, the vertical movement of the distribution stage 60 will be described in the lateral movement of the distribution stage 60 from the right position to the left position and the lateral movement from the left position to the right position. Although omitted, the vertical movement is accompanied when the distribution stage 60 moves laterally as described below.

That is, the vertical movement of the above-mentioned distribution stage 60 during lateral movement from the right position to the left position is as shown in FIG.
7 and FIG. 18 and FIG. 19 showing the operation from FIG. In FIG. 17, the distribution stage 60 is at the right position with the top plate surface aligned with the first transfer path 31, the second transfer path 91, and the third transfer path 91 ′ (not shown) (from the downstream side in FIG. 17). Therefore, in the first slit 62 of the distribution stage 60, the first chuck 71 has released the grip of the electrolytic capacitor array nC ₂ (the left side in the drawing. (Dotted line in FIG. 14). When the distribution stage 60 is laterally moved from the right position to the left position, each head H of the electrolytic capacitor array nC ₂ is caught by the rubber piece 79 of the first chuck 71.

Therefore, from the state shown in FIG.
The air cylinder 68 for vertical movement of 0 is operated to lower the distribution stage 60 to the position indicated by the alternate long and short dash line in FIG. 18, and after pulling out the electrolytic capacitor array nC ₂ from the first chuck 71, the position indicated by the solid line in FIG. It is laterally moved to one side position (right side in FIG. 18). Then, the air cylinder 68 for vertical movement is operated again, and the distribution stage 60 is moved to the position shown in FIG.
9 is moved up to the position of 9, and the top surface of the distribution stage 60 is
Since the top plate surfaces of the first transfer path 31, the second transfer path 91, and the third transfer path 91 ′ are aligned with each other, the electrolytic capacitor array nC ₂ on the first slit 62 of the distribution stage 60 is next moved to the second chuck 72. Then, it is ready to be grasped by and moved to the slit 95 of the second transfer path 91. When the distribution stage 60 is laterally moved from the left position to the right position, the same vertical movement of the distribution stage 60 is performed.

As described above, the horizontal reciprocation between the left position and the right position accompanied by the vertical movement of the distribution stage 60,
The forward and backward movements between the front and rear positions of the chuck group 70 are cooperatively performed, and the 6
The mmφ electrolytic capacitors C are distributed to the second transfer path 91 and the third transfer path 91 ′ as the electrolytic capacitor rows nC for five capacitors and distributed.

With reference to FIGS. 2 and 3, the drive section 51 'common to the second transfer path 91 and the third transfer path 91' is linearly vibrating in the direction of arrow d, so that the second transfer path 91 ' , The electrolytic capacitor array nC distributed to the third transfer path 91 ′ is transferred in the direction of arrow e, and is supplied to the subsequent downstream process. The overflow sensor 101 at the upstream end and the fall / transfer break sensor 102 at the downstream end provided in the second transfer path 91 and the third transfer path 91 ′ are the overflow sensor 101 and the fall / transfer in the first transfer path 31, respectively. It operates in the same manner as the cutoff sensor 102, and when an overflow, falling, or transfer breakage is detected in the electrolytic capacitor array nC, the entire device is stopped, and a pilot lamp (not shown) prompts the operator to normalize and restart.

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

For example, in this embodiment, when the distribution stage 60 is laterally moved, the first slit 62 of the distribution stage 60,
Alternatively, the distribution stage 60 was moved up and down in order to avoid contact between the electrolytic capacitor array nC in the second slit 63 and the first chuck 71, but the distribution stage 60 is only moved laterally in the direction of arrow q, and the chuck group is moved. In addition to the original movement in the front-back direction, 70 may be moved up and down when the distribution stage 60 is moved laterally.

That is, as shown in FIG. 20, the distribution stage 60 is moved only by the air cylinder 67 for lateral movement indicated by the arrow q, and the frame main plate 81 'fixing the chuck group 70 and a frame integral with this. Horizontal plate 81
A fixed portion 68f 'of an air cylinder 68' for vertically moving a'and 81b 'is attached to a sliding member 84 in the front-rear direction, and a moving portion 68d' is attached to a frame main plate 81 '.
As a result, the chuck group 70 can move in the vertical direction indicated by the arrow q in addition to the original movement in the front-back direction. That is, from the state shown in FIG. 20, first, the frame main plate 81 'and the frame lateral plates 81a', 8 which fix the chuck group 70 are first.
1b 'is raised, and then the distribution stage 60 is moved to the left position (right in FIG. 20) to be in the state of FIG. By moving down the frame main plate 81 'and the frame lateral plates 81a' 81b 'from the state of FIG. 21, the movement of the distribution stage 60 to the left position is completed. The same applies to the case where the distribution stage 60 is moved from the left position to the right position.
After raising a'and 81b ', the distribution stage 60 is moved to the position indicated by the alternate long and short dash line.

In this embodiment, the electrolytic capacitor array nC is used.
From the first transfer path 31 to the second transfer path 91 and the third transfer path 9
Although it is divided into two rows of 1 ', other divisions are possible. For example, FIG. 22 is a plan view showing a modified example of the distribution mechanism that distributes from one row of transfer paths 100 to four rows of transfer paths 101, 102, 103, 104 by the first distribution stage 110 and the second distribution stage 120. However, the transfer path 10
0 of the electrolytic capacitor array nC to the first distribution stage 11
0 slits 111 or slits 112 and then, for example, the electrolytic capacitor array nC in the slits 112.
Is distributed to the transfer path 103 and the transfer path 104 by the slit 123 or the slit 124 of the second distribution stage 120. Similarly, the electrolytic capacitor array nC in the slit 111 of the first distribution stage 110 is distributed to the transfer path 101 and the transfer path 102. The movement of the electrolytic capacitor array nC during this time is performed by the forward and backward movement of the chuck group 70 from the chuck 131 to the chuck 137.

Further, as a similar distribution mechanism into four rows,
Other modifications, such as that shown in FIG. 23, are possible. That is, the transfer passages 281, 282, 2 in four rows from the transfer passage 200
83, 284 are distributed to the first distribution stage 210, the stationary stage 220, and the second distribution stage 23.
0, the third distribution stage 240, and the first chuck group 25.
0 chucks 251, 252, 253, chucks 261, 262, 263 of the second chuck group 260 and chucks 271, 272, 273 of the third chuck group 270 are provided.

Electrolytic capacitor array nC in transfer path 200
Are distributed to the slits 221 and the slits 222 of the stationary stage 220 by the cooperation of the first distribution stage 210 and the first chuck group 250, and the operation is the same as that of the present embodiment.

As a next step, for example, the electrolytic capacitor array nC in the slit 221 of the stationary stage 220 is transferred to the transfer path 281 by the cooperation of the second distribution stage 230 and the second chuck group 260 as in this embodiment. It is distributed to the path 282. Electrolytic capacitor row nC
Is in the slit 222 of the stationary stage 220,
Similarly, it is distributed to the transfer path 283 and the transfer path 284. In this way, the electrolytic capacitor row nC of the transfer path 200 is distributed to the four rows of the transfer paths 281, 282, 283, 284.

Further, in this embodiment, the electrolytic capacitor C in the first transfer path 31 is connected to the shorter lead wire La first.
The longer lead wire Lb was transferred while giving a directionality to the rear, but depending on the combination of the width change of the slit 35 and the guide plate 36, the longer lead wire Lb is first and the shorter lead wire La is first. It is also possible to give a later direction.
Further, the device of the present embodiment can be applied to the distribution of film capacitors, which does not require directivity, and electronic parts such as field effect transistors (FET) having lead wires other than capacitors, Other than these, it can also be applied to the distribution of screws including a head and legs, and other work with legs.

In this embodiment, the electrolytic capacitor array nC is used.
To move the chucks 71, 7 by an air cylinder.
Although gripped by 2, 73, the electrolytic capacitor array nC may be gripped and released by an electromagnetic chuck operated by a solenoid.

In the above embodiment, the second transfer path 9 is also used.
The first and third transfer paths 91 'are provided in the second linear vibration part feeder 90, and the common linear vibration drive parts (55', 5 '
8 '), but it is driven by another linear driving unit to be a separate body, and the slits of the distribution stage 60 are arranged in parallel so that the slits are aligned as in the embodiment. You may do it. However, even if both are provided in the linear vibration parts feeder 90 driven by one linear driving unit as in the embodiment, the second transfer path 91 and the third transfer path 91 and the third transfer path 91 are always the same in amplitude even if the constant amplitude control is not performed. Since the transfer path 91 'vibrates, the supply timing to the next process can be made equal, and the second transfer path 91 is always kept at the same timing even if the above-mentioned movement timing is constant in the upstream distribution stage 60. And the work C with feet from the third transfer path 91 '
Can be supplied.

[0067]

As described above, according to the apparatus for distributing and supplying the work with feet according to the present invention, the work with feet from one line of the transfer path is operated by the cooperation of the distribution stage and the chuck group.
Since it can be distributed to the rows or more rows without being entangled with the legs and the work pieces falling down and distributed to the downstream side, it is possible to also use the torsional vibration parts feeder which conventionally required one unit for each destination. Therefore, the equipment cost can be reduced.

Further, with respect to the work with legs, it is possible to perform the distribution by giving the directionality depending on the difference in the length of the legs,
In this case, it is possible to change to the conventional method of giving directionality manually or by a robot, so that the effect of labor saving and reduction of equipment cost is extremely large.
