Description

[Detailed description of the invention] Industrial application field The present invention is designed to transport rod-shaped electronic components such as leadless fixed resistors, diodes, and capacitors, and other rod-shaped components with their axes in a direction perpendicular to the transport direction. This invention relates to a feeding device for rod-shaped parts that is fed to manufacturing processes, packaging processes, etc.

BACKGROUND 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 a rod-like element r1, which is an insulator, shown in FIG. 3A, as shown in FIG. A coating film r3 is formed on the outer periphery of the coating film r1, and after drying, as shown in FIG. 3D, a plurality of color codes r4 are applied to the outer periphery of the coating film r3 and dried.

Therefore, in order to fit the cap r2 on both sides of the rod-like element r1, a capping device (for example, a
52-31382, 55-6094)), the rod-shaped element r1 and the cap are supplied to the element groove in the center of the press-fit rotor and the cap grooves on both sides, respectively.
The caps r2 on both sides are advanced relative to the rod-shaped element r1 by advancing the press-fit pin supported by the pin rotor on the downstream side in the rotational direction of the press-fit rotor and the pin rotors on both sides of the supply position.

As an example of a conventional supply device for supplying the element r1 to the press-fit rotor, a configuration as shown in FIGS. 4 and 5 is known. To explain this conventional example, a bearing 102 is attached to a pedestal 101, and a rotating shaft 103 is rotatably supported by the bearing 102. A supply wheel 104 is mounted on the rotating shaft 103, and this supply wheel 104
A large number of storage grooves 105 are formed at approximately equal intervals on the outer periphery of the storage groove 105 for storing the rod-shaped elements r1 horizontally, that is, with their axes parallel to the rotation center axis of the supply wheel 104. The supply wheel 104 is connected to a stepper motor 106, and is intermittently rotated by the stepper motor 106. The chute 107 for supplying the rod-shaped element r1 to the storage groove 105 located above has a curved part formed at the lower part of the vertical part, and a horizontal part is formed following the curved part, and this horizontal part communicates with the storage groove 105. has been done. The vertical portion of this chute 107 is supported by a support member 108 on the pedestal 101, and the horizontal portion is supported by a guide member 110, which will be described later. The rod-shaped elements r1 are sequentially fed into the shoot 107 from a parts feeder (not shown), and are fed into the shoot 107.
06, it is vertically oriented and sequentially lowered by its own weight, diagonally, then horizontally, and is sequentially supplied to the storage groove 105 of the supply wheel 104 which is rotating intermittently.
Guide members 119 and 110 are provided to prevent the rod-shaped element r1 from leaving the storage groove 105 during the period from the upper supply position to the lower discharge position.

Then, the rod-shaped element r1 is oriented vertically and the chute 1 is
Storage groove 1 of the supply wheel 104, which is lowered by its own weight in 07, turned sideways, and rotates intermittently.
05 sequentially. The rod-shaped element r1 stored in the storage groove 105 is transferred downward as the supply wheel 104 rotates intermittently, and when it leaves the guide member 110, it falls, thereby being able to be supplied to the element groove of the press-fit rotor.

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

In the manufacturing process, packaging process, etc. of not only the rod-shaped element r1 but also various rod-shaped parts,
In order to speed up the work by shortening the transfer interval of the rod-like elements r1, etc., as in the capping device described above, the rod-like elements r1, etc. are oriented so that their axes are perpendicular to the direction of transport. In order to supply the rod-shaped elements r1, etc. using the supply wheel 104 in such manufacturing processes, packaging processes, etc., in order to match the timing of transferring the rod-shaped elements r1, etc., the axis of the rod-shaped elements r1, etc. is aligned with the supply wheel. It is necessary to supply the material parallel to the rotation center axis of 104, that is, in a direction perpendicular to the transport direction.

However, in the case of the former, the frictional resistance between the rod-like element r1 and the chute 107 is large in the curved portion and the horizontal portion of the chute 107, which not only causes friction scratches on the rod-like element r1, but also causes the supply The speed is slow, and there is a limit to how quickly the supply work can be done. Especially shoot 10
When there are only a few rod-like elements r1 left in 7 and the pushing force from the rear becomes weak, the rod-like elements r1 cannot be supplied to the storage groove 105 due to frictional resistance.
Moreover, if the front side part of the rod-shaped element r1 enters the storage groove 105 and the rear part remains in the chute 107,
This causes troubles such as damage to the supply wheel 104 and disruption of the overall conveyance timing due to the impact load. Moreover, if the rod-like element r1 remains in the horizontal part of the chute 107, when the rod-like element r1 of a different standard is supplied, the rod-like element r1 of a different type
This results in manufacturing troubles.

On the other hand, in the latter case, if a space is created in the upper part of the chute, there is a possibility that the rod-shaped element r1 that is subsequently supplied into the chute may enter the chute in an oblique direction, and there is a possibility that the rod-shaped element r1 may not be supplied. In addition, the rod-like element r1 may become obliquely jammed in the middle of the chute or at the exit, and may become unable to be fed, damaging the chute and making it impossible to speed up the feeding operation.

The present invention solves the problems of the prior art as described above, and allows rod-shaped parts to be quickly and reliably fed into the storage groove of the feeding wheel, thereby preventing the occurrence of trouble and improving the feeding process. This can increase the speed of the process, and also prevents scratches on rod-shaped parts inside the chute, damage to the chute, damage to the supply wheel,
It is possible to prevent supply troubles, etc., and to transport the rod-shaped parts so that their axis is perpendicular to the direction of transport, and to adjust the timing of feeding the rod-shaped parts to the press-fit rotor, etc. in the manufacturing process and packaging process. To provide a feeding device for rod-shaped parts, which can help speed up the work such as the above, and can further prevent the end face of the rod-shaped parts from being damaged during the transfer of the rod-shaped parts. The purpose is to

Means for solving the problem The technical solution of the present invention to achieve the above object is that a large number of storage grooves for rod-shaped parts are formed at approximately equal intervals on the outer periphery, and the extension line of the groove bottom of each storage groove is A supply wheel tilted in the same direction so as to intersect on an extension line of the rotation center axis, a device for rotating the supply wheel intermittently, and a rod-shaped component is inserted into the storage groove of the supply wheel from the upper side in the direction of inclination of the storage groove. a chute for supplying in an inclined state substantially equal to the inclination direction of the storage groove; and a rod-shaped component provided to be able to rotate together with the supply wheel on the lower side in the inclination direction of the storage groove, and supplied to the storage groove from the chute. a stopper member for receiving the rod-shaped parts so as to be positioned in the storage groove; and a support member that horizontally supports the rod-shaped component on the downstream side in the rotational direction.

Then, as the supply wheel rotates intermittently, the tilted rod-shaped part stored in the tilted storage groove is held by a support member on the downstream side in the rotation direction of the supply wheel so that its axis is aligned with the rotation center axis of the supply wheel. The material can be transported while being supported in a horizontal direction that is substantially parallel to the surface, discharged downward from the end of the support member, and supplied to a press-fit rotor or the like.

This support member 7
is composed of 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.
This support member 7 prevents the rod-shaped element r1 supplied to the storage groove 4 from leaving the storage groove 4 when it is transferred downward as the supply wheel 2 rotates,
Moreover, the rod-shaped element r1 can be supported in the horizontal direction by the support surface 8 on the downstream side in the rotational direction of the supply wheel 2. The rotating shaft 1 is connected to a stepper motor (not shown) via a power transmission mechanism (not shown), and the stepper motor is supported by a frame or the like.
