Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention is directed to rod-shaped electronic components such as leadless fixed resistors, diodes, and capacitors, and other rod-shaped components whose axis is perpendicular to the transfer direction. The present invention relates to a device for supplying rod-shaped parts which are supplied to a manufacturing process, a packaging process, etc.

2. Description of the Related Art Recently, so-called leadless rod-shaped fixed resistors have been used. For example, to manufacture a fixed resistor, caps r2 are fitted on both sides of an insulator rod-shaped element r1 shown in FIG. 3A as shown in FIG. 3B, and a rod-shaped element is shown as shown in FIG. 3C. A coating film r3 is formed on the outer periphery of r1, and after drying, FIG. 3D
As shown in, multiple lines of color code r on the outer periphery of the coating film r3
4. Apply and dry.

Thus, to fit the caps r2 on both sides of the rod-shaped element r1, a capping device (for example, Japanese Utility Model Publication No. 52-31382) is used.
No. 5,55-6094, etc.), the rod-shaped element r1 and the cap r2 are respectively supplied to the element groove in the central portion and the cap grooves on both sides of the press-fit rotor, and the press-fit rotor and both sides thereof are supplied from these supply positions. The cap r2 on both sides is advanced relative to the rod-shaped element r1 by advancing a press-fitting pin supported by the pin rotor on the downstream side in the rotation direction of the pin rotor.

As a conventional example of a supply device for supplying the rod-shaped element r1 to the press-fit rotor, configurations shown in FIGS. 4 and 5 are known. Explaining this conventional example, the gantry 1
A bearing 102 is attached to 01, and a rotating shaft 103 is rotatably supported by the bearing 102. A supply wheel 104 is mounted on the rotary shaft 103, and a storage groove 105 for storing the rod-shaped element r1 laterally on the outer periphery of the supply wheel 104, that is, so that its axis is parallel to the rotation center axis of the supply wheel 104. Are formed at substantially equal intervals. The supply wheel 104 is linked to the stepper motor 106, and is intermittently rotated by driving the stepper motor 106. A chute 107 for supplying the rod-shaped element r1 to the storage groove 105 located on the upper side.
The curved portion is formed in the lower part of the vertical portion, the horizontal portion is formed following the curved portion, and the horizontal portion is communicated with the storage groove 105. A vertical portion of the chute 107 is supported by the supporting member 101 by the support member 108, and a horizontal portion thereof is supported by a guide member 110 described later. The rod-shaped element r1 is sequentially fed into a chute 107 from a parts feeder (not shown), and vertically descends in the chute 106 by its own weight, and then turns diagonally and laterally, and the intermittently rotating supply wheel 104 is stored. It is sequentially supplied to the groove 105. Between the supply position on the upper side and the discharge position on the lower side, the rod-shaped element r

09 and 110 are provided.

Then, the rod-shaped element r1 is vertically oriented and lowered by its own weight in the chute 107, and is converted laterally to be sequentially supplied to the accommodation groove 105 of the intermittently rotating supply wheel 104.
The rod-shaped element r1 accommodated in the accommodating groove 105 is transferred downward due to intermittent rotation of the supply wheel 104, and is guided by the guide member 1
When 10 is released, it drops and can be supplied to the element groove of the press-fit rotor.

Further, as another conventional example of the supply device, the rod-shaped element r1 is laid sideways and dropped by its own weight in the chute, and is transferred downward by the storage groove of the supply wheel similar to the above, or directly, the element groove of the press-fit rotor. There is one that is designed to be supplied to.

In addition to the rod-shaped element r1, in the manufacturing process of various rod-shaped parts, the packaging process, etc., in order to speed up the work by shortening the transfer interval of the rod-shaped element r1 etc. as in the capping device, The rod-shaped element r1 and the like are oriented so that the axis thereof is orthogonal to the transfer direction. In order to supply the rod-shaped element r1 and the like by using the supply wheel 104 in the manufacturing process, the packaging process and the like, the axis of the rod-shaped element r1 and the like is supplied to the supply wheel in order to match the transfer timing of the rod-shaped element r1 and the like. It is necessary to supply in parallel with the central axis of rotation of 104, that is, in the direction orthogonal to the transfer direction.

However, in the former case, the frictional resistance between the rod-shaped element r1 and the chute 107 is large in the curved portion and the horizontal portion of the chute 107, and not only the rod-shaped element r1 is not scratched but also the supply is reduced. The speed is slow and there is a limit to the speeding up of the feeding work. In particular, when the rod-shaped element r1 in the chute 107 is reduced and the pushing force from the rear is weakened, the rod-shaped element r1 cannot be supplied to the storage groove 105 due to frictional resistance. Moreover, if the front side portion of the rod-shaped element r1 enters the storage groove 105 and the rear half portion remains in the chute 107, the supply wheel 104 is damaged, and a shock load causes a trouble such as deviating the entire transfer timing. . If the rod-shaped element r1 remains in the horizontal portion of the chute 107, different types of rod-shaped elements r1 are supplied when the rod-shaped elements r1 having different standards are supplied, which causes a manufacturing trouble.

On the other hand, in the latter case, if a space is formed in the upper part of the chute, the rod-shaped element r1 to be supplied into the chute thereafter may enter in an oblique direction, and there is a possibility that the supply becomes impossible. Further, the rod-shaped element r1 may be blocked in the middle of the chute or even at the outlet portion in an oblique direction and may be unable to be supplied.
The chute is damaged and the feeding work cannot be speeded up.

Further, in any of the conventional supply devices, the supply wheel has to be intermittently rotated, which also limits the speeding up of the supply work.

The present invention solves the problems of the prior art as described above, and it is possible to rapidly and reliably supply the rod-shaped component to the storage groove of the supply wheel, and therefore, the damage of the rod-shaped component in the chute occurs. , Chute damage, supply wheel damage,
It is possible to prevent supply troubles, etc., and to transfer the rod-shaped parts so that the axis of the rod-shaped parts is in the direction orthogonal to the transfer direction, and to supply the rod-shaped parts to the press-fit rotor, etc. at the same manufacturing and packaging processes. It is possible to cooperate with the speeding up of the work such as, and it is possible to speed up the supply work by making it possible to continuously rotate the supply wheel,
Another object of the present invention is to provide a rod-shaped component supply device capable of preventing the end surface of the rod-shaped component from being damaged during the transfer of the rod-shaped component.

Means for Solving the Problems And the technical means of the present invention for solving the above-mentioned problems is to form a large number of accommodating grooves of rod-shaped parts at substantially equal intervals on the outer periphery, and to extend the groove bottom of each accommodating groove. Are inclined in the same direction so as to intersect with each other on the extension line of the rotation center axis, and the width of the storage groove in the circumferential direction is formed to be narrower than the width in which two rod-shaped parts are arranged in parallel so that the axis of the rod-shaped part is along the above-mentioned inclination direction. A supply wheel, a device for continuously rotating the supply wheel, and a chute for supplying a rod-shaped component into the storage groove of the supply wheel from the upper side in the inclination direction of the storage groove in an inclined state substantially equal to the inclination direction of the storage groove. A stopper member that is provided so as to rotate integrally with the supply wheel on the lower side of the storage groove in the inclination direction and that receives the rod-shaped component supplied from the chute into the storage groove so as to be positioned in the storage groove; The rod-shaped parts supplied to the storage groove are prevented from being separated from the storage groove when the bar-shaped parts are transferred downwards as the supply wheel rotates,
Further, it is provided with a support member for supporting the rod-shaped component in the horizontal direction on the downstream side in the rotation direction of the supply wheel.

Action The action of the above technical means is as follows.

The rod-shaped parts that are smoothly and reliably fed in the inclined state by the pushing force of the rod-shaped parts in the rear of the chute and the self-weight in the inclined storage groove of the continuously rotating supply wheel in the inclined state Is received by a stopper member that rotates with the supply wheel and is positioned in the storage groove. Then, the rod-shaped component in the inclined state housed in the housing groove inclined with the continuous rotation of the supply wheel is supported by the support member on the downstream side in the rotation direction of the supply wheel so that the axis of the bar-shaped component is the rotation center axis of the supply wheel. It can be transported in a state of being supported in a horizontal direction that is substantially parallel to, discharged below the end of the support member, and supplied to a press-fitted rotor or the like.

FIG. 1 is a vertical sectional view showing an embodiment of the present invention, and FIG. 2 is a right side view thereof.

This embodiment is carried out when the rod-shaped element r1 as the rod-shaped component shown in FIG. 3A is supplied to the press-fit rotor. The rotating shaft 1 is supported by a bearing (not shown) attached to a frame (not shown), and the supply wheel 2 is attached to the rotating shaft 1. That is, the boss portion 3 provided integrally with the supply wheel 2 is fitted to the rotary shaft 1,
It is fixed to the rotary shaft 1 by a screw (not shown) or the like.
A large number of storage grooves 4 are formed on the outer periphery of the supply wheel 2 at substantially equal intervals. Each storage groove 4 is inclined in the same direction so that the extension line of the groove bottom intersects with the extension line of the rotation center axis C of the supply wheel 2. The width of each storage groove 4 in the circumferential direction is wider than the diameter of the rod-shaped element r1, and is slightly narrower than the width in which two rod-shaped elements r1 are arranged side by side so that the axis of the rod-shaped element r1 is along the tilt direction, that is, two elements r1. Are formed so as not to be supplied to one storage groove 4. A chute 5 located on the upper side of the supply wheel 2 for supplying the rod-shaped element r1 to the storage groove 4.
Is provided. The chute 5 is supported by a gantry or the like, and at least the tip end side thereof is inclined so as to be able to supply the rod-shaped element r1 from the upper side in the inclination direction of the storage groove 4 in an inclined state substantially equal to the inclination direction of the storage groove 4. The base of the chute 5 communicates with a parts feeder (not shown). A disk-shaped stopper member 6 is provided on the lower side of the storage groove 4 in the inclination direction, is integrally provided with the boss portion 3, and is rotated integrally with the supply wheel 2. With this stopper member 6, the rod-shaped element r1 supplied from the chute 5 to the storage groove 4 can be received so as to be positioned in the storage groove 4. A support member 7 is provided on the outer peripheral portion of the supply wheel 2 between the upper rod-shaped element supply position and the lower discharge position, and the support member 7 is supported by a mount or the like. The support member 7 has a support surface 8 that curves along the outer peripheral surface of the supply wheel 2.
And a guide portion 9 that covers the side of the storage groove 4 on the opposite side of the stopper member 6. The support member 7 prevents the rod-shaped element r1 supplied to the storage groove 4 from being detached from the storage groove 4 when the rod-shaped element r1 is transferred downward as the supply wheel 2 rotates, and the support surface 8 prevents the supply wheel 2 from moving. The rod-shaped element r1 can be horizontally supported on the downstream side in the rotation direction. The rotating shaft 1 is connected to a motor (not shown) via a power transmission mechanism (not shown), and the motor is supported by a mount or the like.

A press-fit rotor 10 is provided below the supply wheel 2. The press-fitting rotor 10 is arranged such that its rotation center axis is parallel to the rotation center axis C of the supply wheel 2, and a large number of element grooves 11 are formed on the outer periphery of the central portion in parallel with the rotation center axis at substantially equal intervals. A large number of cap grooves 12 are formed on the outer periphery of both sides so as to be in the same row as the element grooves 11. The press-fitting rotor 10 is rotated by a rotating device (not shown), and the element groove 11 thereof sequentially corresponds to the housing groove 4 of the supply wheel 2.

Next, the operation of the above embodiment will be described.

The rod-shaped elements r1 are sequentially supplied to the chute 5 from the parts feeder. The rod-shaped element r1 descends in the chute 5 due to the pushing force of the rear rod-shaped element r1 and its own weight, and becomes an inclined direction at the inclined portion of the tip portion, and in that state the inclination of the supply wheel 2 that is continuously rotating by the drive of the motor. It is sequentially supplied to the storage groove 4. At this time, since the storage groove 4 is formed wider than the diameter of the rod-shaped element r1 as described above, the supply time of the rod-shaped element r1 can be lengthened and the rod-shaped element r1 can be continuously rotated even if the supply wheel 2 is continuously rotated. Can be reliably supplied to the storage groove 4. The supplied rod-shaped element r1 is received by the stopper member 6, and the inclined storage groove 4 is received.
It is stored in a slanted state. With the continuous rotation of the supply wheel 2, the rod-shaped element r1 housed in the housing groove 4 is supported by the support member 7 and transferred. At this time, since the rod-shaped element r1 has a round rod shape, the rod-shaped element r1 rolls on the support surface 8, so that the outer peripheral surface is not likely to be damaged. Further, since the stopper member 6 is rotated integrally with the supply wheel 2 as described above, it is possible to prevent the end face of the rod-shaped element r1 from being scratched. On the downstream side in the rotation direction, the rod-shaped element r1 is transferred horizontally by the support surface 8, that is, the axis is transferred in the direction orthogonal to the transfer direction, and is discharged downward from the end of the support member 7, and the press-fit rotor 10 is inserted. Element groove 11
Are sequentially supplied. At this time, although the storage groove 4 is formed wider than the diameter of the rod-shaped element r1 as described above, the rod-shaped element r1 on the support surface 8 is pressed by the inner wall of one side of the storage groove 4 to be transferred, so that the supply is performed. The position is always constant, and there is no fear of deviation in the supply timing.

Although the stopper member 6 is provided integrally with the boss portion 3 in the above embodiment, it may be provided on one side of the supply wheel 2 itself.

As described above, according to the present invention, the storage groove for the parts of the supply wheel is inclined in the same direction so that the extension line of the groove bottom intersects with the extension line of the rotation center axis, and the circumference of the storage groove is increased. The width in the direction is formed so as to be narrower than the state in which two rod-shaped parts are arranged in parallel so that the axis of the rod-shaped parts is along the above-mentioned inclination direction, and the rod-shaped parts are formed by the chute into the inclined storage groove of the continuously rotating supply wheel. It is supplied in the same inclination state as the storage groove, and this rod-shaped part is received by a stopper member that rotates integrally with the supply wheel and positioned inside the storage groove. With the continuous rotation of the supply wheel, the rod-shaped parts stored in the storage groove The parts are horizontally supported and transferred by the supporting member on the downstream side in the rotation direction of the supply wheel, and discharged downward from the end of the supporting member.
It is designed to be supplied to a press-fitted rotor or the like. In this way, since the rod-shaped parts are fed in the inclined storage groove of the feed wheel in the inclined direction, it is possible to reduce the frictional resistance between the chute and the rod-shaped parts, and moreover, the rod-shaped parts do not get clogged in the chute, so that a supply trouble is prevented. It is possible to prevent and supply to the supply wheel quickly and reliably. Therefore, it is possible to prevent the rod-shaped part from being damaged, the chute from being damaged, and the supply wheel from being damaged. In addition, since the rod-shaped component can be reliably discharged from the chute, troubles such as manufacturing and packaging due to mixing of different rod-shaped components can be prevented. In addition, since the storage groove is formed wide as described above, the rod-shaped component can be supplied to the storage groove even when the supply wheel is continuously rotated, so that the rod-shaped component can be quickly supplied to the press-fit rotor or the like. It is possible to speed up the supply work. In addition, since the rod-shaped parts are transferred with their axes centering in the direction orthogonal to the transfer direction, the timing for supplying the rod-shaped parts to the press-fitting rotor, etc. can be adjusted, and the manufacturing process, packaging process, etc. can be speeded up. Can cooperate with. Furthermore, since the stopper member that receives the end of the rod-shaped component is rotated integrally with the supply wheel, it is possible to prevent the end face of the rod-shaped component from being scratched during the transfer.
