The guide 82W is also added to the suspension plate 82 on the inner peripheral side in mm, the component C is transferred in an upright posture, and a rubber magnet 38D is laid in a belt shape directly below the leads La and Lb. And the part C
To prevent them from jumping out.

Referring to FIGS. 2 and 3, the discharge end of torsional vibration parts feeder 2 is connected to the upstream end of trough 84 of linear vibration parts feeder 3 with a predetermined gap. The linear vibration parts feeder 3 includes a trough 84 for transferring the parts C in a single row, and a drive unit 90 for applying linear vibration to the trough 84.

In the driving section 90, a movable block 92 connected to a bottom plate 83 of a trough 84 by bolts 91 is fixed to a lower fixed block 94 by a pair of front and rear inclined leaf springs 93.
Is linked to An electromagnet 96 on which a coil 95 is wound is provided on the fixed block 94 so as to face the movable core 92C hanging from the movable block 92 with a slight gap.
Is installed. Further, the fixed block 94 is connected to a height adjusting block 99A of a gantry 99 installed on the floor surface via a pair of front and rear inclined vibration plate springs 97. That is, the gantry 99 is fixed to the floor surface with the bolts 99b, and the height adjustment block 99A is fixed to the nut 9 with respect to the bolt 98 screwed to the top plate block 99B of the gantry 99.
The height of the trough 84 is adjusted by adjusting the height of the torsion vibrating part feeder 2 with the height of the trough 84 by adjusting the height of the torsion vibrating parts feeder 2. Then, when an alternating current is supplied to the coil 95, the trough 84 is given a linear vibration indicated by an arrow q.

Since the cross section of the trough 84 is substantially the same as that of FIG. 15, the corresponding components are denoted by the same reference numerals with ('), and the description of the cross section is omitted.
A suspension plate with a guide 81W 'and a suspension plate with a guide 82W' for suspending and transferring the component C in an upright position are provided at the upper portion of the upper part 4, and a belt-like rubber magnet 38 is provided immediately below the suspension plate.
D 'is laid. A side plate 86 with a window is detachably attached to a side surface of the trough 84.

A light-blocking overflow sensor 87 is installed on the surface of the trough 84 so as to be oblique to the transfer path of the component C. When the component C is normally transferred, the light from the light emitting element 87a to the light receiving element 87b is intermittent, but when the light is interrupted for a predetermined number of seconds or more, a controller (not shown) to which the signal is input is inputted. Determines that the component C has clogged in the transfer on the trough 84, and stops the torsional vibration parts feeder 2 on the upstream side.

The device 1 for feeding parts C according to the embodiment is constructed as described above. Next, the operation thereof will be described.

Referring to FIGS. 2 and 3, alternating current is applied to coil 15 in drive unit 11 of torsional vibration parts feeder 2, and torsional vibration is applied to bowl 21 accommodating many components C. It is assumed that air is jetted from the air jet nozzles 41, 43, 47 arranged in the bowl 21. Further, it is assumed that an alternating current is supplied to the coil 95 in the drive unit 90 of the linear vibration parts feeder 3 to apply linear vibration to the trough 84, and that the overflow sensor 87 installed in the trough 84 is also in operation. I do.

In the bowl 21, the component C on the bottom surface 22 is moved to the peripheral portion under the torsional vibration, and is orientated and transported in the direction indicated by the arrow m with the head H or the leads La and Lb at the head. Then, the user gets on the flat track 24 from the starting point 24s. At a position where the flat track 24 is spirally raised and makes substantially one round, the component C being transferred on the inner peripheral side of the flat track 24 drops from the narrow portion 24n having a reduced width and returns to the bottom surface 22. ,
The transfer amount is adjusted. The remaining part C further contacts the peripheral wall 23, and the flat track 24 whose width is gradually reduced.
Is transported, the transport amount is adjusted, and is assisted by the air ejected from the air ejection nozzle 41 in the wide and long delivery direction truck 34 provided with the peripheral wall 23 missing at the downstream end of the flat plate truck 24. The component C is guided to the outer peripheral side of the bowl 21 and suspended.

[0049] That is, referring to FIG. 5, by the centrifugal force component of the transfer force by torsional vibration, component C is locked to the head H to the outer peripheral edge and restraining plate 35 with a gap S ₁ derived track 34 leads La and Lb are inserted, and the leads La and Lb are suspended by being attracted by the rubber magnet 38A laid on the outer peripheral side, but as shown in FIG. Is extended long, and with the aid of the jet air from the air jet nozzle 41 described above, although there are some components C that fall downward from the downstream end of the lead-out truck 34, the suspension efficiency is low. Kept high. The air ejected toward the head H from the air ejection nozzle 43 on the upstream side is also assisted, and the part C is smoothly transported on the suspension track 44 having the same inclination following the lead-out track 34.

Next, as shown in FIGS. 4 and 8, the parts C are supported by the lead tracks 54 at the roots of the leads La and Lb by dropping the suspension track 44 so that the tip of the lead track 54 is held down. the head H is engaged in the gap S ₂ between the lower end of the plate 35, it is transported is sucked to lead La, Lb by a rubber magnet 38B which is added the rubber magnet 38A of the outer peripheral wall 37 of the pocket 36. At this time, the component C having the bent leads La and Lb and not being affected by the attraction force of the rubber magnets 38A and 38B is provided on the receiving plate 5
8 and slides down to be received in the lower pocket 36. Since the receiving plate 58 is widened from the upstream side to the downstream side, the contact angle of the head H changes continuously, and the lead L
a, depending on the curvature of Lb, lead La, Lb fall out in the most omission likely angle from the gap S _2. The component C that has fallen into the pocket 36 is assisted by the air jetted from the air jet nozzle 47 fixed to the support 32, and is transported downstream in the pocket 36.

[0051] Further, although part C is shifted to the front and rear straightening unit 60, with reference to FIGS. 9 and 11, locking the bottom head H is in the gap S ₃ of the holding plate 35 and the head track 64 Then, the circumferential portion of the bottom surface is placed on the head receiving surface 65 of the head track 64, and the central portion of the head H is placed on the head receiving plate 66, so that the head H of the component C is rollably supported. Is done. In this state, as shown in the perspective view of FIG. 10, the leads La and Lb of the part C are attracted to the rubber magnets 38A and 38C, and the head H is in contact with the head receiving surface 65 of the head track 64 in contact with the head. The torsional vibration transmitted through the receiving plate 66 receives the rotational force in the backward direction and is transferred.

Then, referring to FIG. 7 and FIG.
a and Lb reach the planar guide plate 67 and ride up from the upstream part which is bent downward.
In the part C whose b is the front side, the short lead Lb is rotated backward about the long lead La strongly attracted by the rubber magnets 38A and 38C, and the short lead Lb contacts the planar guide plate 67 and rotates. Is stopped, the long lead La is moved forward. On the other hand, the component C having the long lead La on the front side is prevented from rotating backward by the planar guide plate 67 in the rotation direction of the short lead Lb, so that it is transported in the same direction. That is, all the components C that have passed through the front-rear correction unit 60 are transported with the long lead La as the front side.
In addition, in the front-rear correction unit 60, the leads La, L
The part C whose b is bent falls down with the head H down and is eliminated because the suction by the rubber magnets 38A and 38C does not reach.

Subsequently, the part C is transferred to the feeder 70. The head receiving plate 66 is missing, the downstream portion 67a of the planar guide plate 67 is bent downward, and the rubber magnet 38C
After the upper end surface of the vertical guide plate 77 supporting the long lead La is lowered, the levels of the leads La and Lb are lowered, and the level of the head H is raised.
, The head track 64 is the lead track 74, so that the part C loses the support of the head H and the lead La
Of the lead Lb and the root of the lead Lb
, The rotation of the lead La is stopped, and the leading end of the long lead La is transferred by being supported by the vertical guide plate 77. And
The lower end surface of the holding plate 35 is lowered, and the lead La and the lead L
The clearance S ₄ between the tip of the read track 74 narrower 1.5mm than the outer dimension 2mm of b intervals before and after the short lead Lb of the front long lead La and the rear is transported is prevented from being inverted.

Also in this part, the leads La,
When Lb is bent and there is a part C to which the attraction force of the rubber magnet 38A does not reach, the part C comes into contact with the receiving plate 78 with the heavy head H down and slides down to be removed to the pocket 36. The components C that have fallen into the pockets 36, including those transferred from the upstream side, are returned to the bottom surface 22 of the bowl 21 via the passages 29 opened in the peripheral wall 23 of the bowl 21.

As described above, the mechanism for moving the long lead La of the component C to the front side and the mechanism for removing the bent component C of the leads La and Lb are provided by the long lead La.
And the rubber magnet 38A or the rubber magnet 38A combined with the rubber magnet 38B or the rubber magnet 38C. Magnets 38A, 38B,
38C is fixed to an outer peripheral wall 37 of a pocket 36 attached in an arc shape along the outer peripheral surface of the peripheral wall 23 of the bowl 21. Since the torsional vibration received by the bowl 21 acts in the circumferential direction, the pocket 36 attached along the outer periphery of the bowl 21 has strength against deformation, and the rubber 36 fixed to the outer peripheral wall 37 of the pocket 36 Magnet 38A, 3
8B and 38C also maintain a stable position relative to the bowl 21.

On the other hand, the integrated lead track 54, head track 64, and lead track 7,
4 is formed in an arc shape on the outer peripheral side of the bowl 21 as shown in FIG. 4, and is fixed by the support plate 63 welded to two places on the outer peripheral surface of the peripheral wall 23 of the bowl 21. Also, the bowl 21 is hardly deformed by torsional vibration acting in the circumferential direction, and the position relative to the bowl 21 is stably maintained. Therefore, the tips of the leads La and Lb of the part C to be transferred and the rubber magnets 38A, 38B, 3
8C is also maintained stably, and even after long-term use of the component feeding device 1, the feeding accuracy of transferring the long lead La of the component C as the front side does not decrease.

Next, the part C suspended and transported through the lead track 74 with the leads La and Lb slightly downward to the outer peripheral side is guided to the outside beyond the end face plate 37E of the pocket 36. Referring to the drawing, the long lead La on the front side and the short lead Lb on the rear side are sandwiched from both sides by the suspension plate 81 with the guide 81W and the suspension plate 82, and the rubber magnet 38B is restored to attract the leads La and Lb. At the same time, the slope 74a on the outer peripheral side of the lead track 74
Is gradually erected, the part C is erected.
If there is a component C that is not dropped depending on the bending of the leads La and Lb but is in a horizontal state, the head H contacts the round bar 79 and is guided to the pocket 36, and the leads La and Lb are guided. The bent part C of Lb is finally eliminated.

Further, referring to FIG. 15, a long lead La on the front side of component C and a short lead Lb on the rear side have a distance of 1.5 mm between suspension plate 81 and suspension plate 82 supporting the bottom surface of head H.
Sandwiched in the gap S ₅ is prevented before and after the inversion, is suppressed roll of the head H by being loosely sandwiched between the guide 82W guide 81W and hanger plate 82 of the hanging plate 81 a side of the head H And discharged from the downstream end.

The part C discharged from the torsional vibration parts feeder 2 is connected to the downstream end thereof and has a trough 84 of the linear vibration parts feeder 3 having a cross section similar to the cross section of the downstream end of the bowl 21 shown in FIG. It is transferred to FIG. 2, FIG.
In the trough 84, the bottom surface of the head H is supported by the suspension plate with the guide 81W 'and the suspension plate with the guide 82W', and the sides are loosely clamped, stably transferred one by one in a row, and the next process is performed from the discharge end. Supplied to Further, when the supply and demand balance with the next process is disturbed and the trough 84 is clogged during transfer, and the component C stagnates in the middle of the trough 84, the light emitting element 87a of the overflow sensor 87 installed in the middle of the trough 84 Since the light reaching the light receiving element 87b is blocked, an overflow is detected, and the controller (not shown) to which the signal is input stops the torsional vibration parts feeder 2. When the overflow is eliminated, the torsional vibration parts feeder 2 is restarted because it is detected by the overflow sensor 87.

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

For example, in the present embodiment, the rubber magnet 38A and the like for attracting the leads La and Lb of the component C are directly mounted on the outer peripheral wall 37 of the pocket 36, but other mounting methods may be adopted. For example, it may be attached to the bottom surface of the pocket 36, the outer peripheral wall, or other fixing members fixed thereto.

In the present embodiment, the support plate 63 in which the integrated lead track 54, head track 64, and lead track 74 are welded to the outer peripheral surface of the bowl 21.
But in other places, such as pocket 36
May be attached to a support member fixed to the bottom surface of the.

In the present embodiment, in order to transfer the component C from the flat track 24 to the suspension track 44 and suspend it efficiently, a wide and long lead-out track 34 is employed. Although the air ejection nozzle 41 is attached to assist the suspension, the air ejection nozzle 41 may be omitted if a slight reduction in the suspension ratio is allowed.

In the present embodiment, the cross-sectional shape of the lead track 54 and the lead track 74 installed in the pocket is a wedge shape in which the tip is formed by a slope inclined downward toward the outer peripheral side. If Lb is bent and the component C which cannot be attracted by the rubber magnet 38A or the like falls with the heavy head H down,
The shape does not matter. For example, the track may be a wedge-shaped track having a point formed by a slope inclined downward toward the inner peripheral side, or may be a track having a mountain-shaped cross section.

In this embodiment, the pocket 3
In order to return the component C that has dropped to the inside of the bowl 21 to the inside of the bowl 21, the passage 29 is opened in the peripheral wall 23 of the bowl 21.
The bent parts C of the leads La and Lb may be retained in the pocket 36 without providing the doors, and a door that can be opened and closed may be added to the passage 29 as needed.
