Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a coil spring discharge device for a coil spring transfer facility, in which a coil spring is configured to be pulled and moved in the longitudinal direction of the coil spring by a roller chain on the upper surface of a horizontally extending guide rail and discharged from one end of the guide rail.

[0002]

[Prior art]

 Conventionally, as an apparatus of this type, as disclosed in Japanese Utility Model Publication No. 1-111616, an induction wheel that rotates in a vertical plane is arranged near one end of the guide rail. A roller chain that pulls and moves the coil spring inside is fitted on the rotating shaft of the chain wheel that drives the rotation, and the coil spring that drops from one end of the guide rail after movement is guided to the chute by the guide wheel. is there.

[0003]

[Problems to be solved by the device]

 However, in the conventional device configured as described above, the guided vehicle can properly guide the coil spring to the shoe, especially when the rotation speed of the roller chain is high or the length of the coil spring is long. However, there was a problem that the coil spring could not be properly discharged from the guide rail because the coil spring accumulated near one end of the guide rail. The present invention has been made in view of the above circumstances, and when the speed of the coil spring moved on the guide rail in the longitudinal direction of the coil spring by the pulling of the roller chain is relatively high and the length of the coil spring is compared. An object of the present invention is to provide a coil spring discharging device that can accurately guide a coil spring discharged from a guide rail after movement to a chute even when the length is extremely long.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, a coil spring discharging device according to the present invention includes a guide rail that extends substantially horizontally and can guide the coil spring in the longitudinal direction, and a guide rail that is arranged along the guide rail. The roller chain for pulling and moving the coil spring and the coil spring that is disposed near one end of the guide rail and moves away from the one end of the guide rail after moving on the guide rail are faster than the moving speed by the roller chain. And an induction vehicle mechanism having an induction vehicle main body capable of being delivered by.

[0005]

[Action]

 In the device constructed in this way, the coil spring dropped from one end of the guide rail after being moved in the longitudinal direction of the coil spring on the guide rail by the pulling of the roller chain rotates the guide spring mechanism at a predetermined rotation speed. It will be delivered at a speed faster than the pulling movement of the roller chain by the main body of the guide vehicle.

[0006]

【Example】

 An embodiment of the present invention will be described in detail with reference to FIG. 1 which is a front view and FIG. 2 which is a sectional view taken along line AA of FIG. As shown in FIG. 1, an endless roller chain 2 extending along the first guide rail 1 is provided above the first guide rail 1 which extends horizontally and can guide the coil spring in the longitudinal direction. The endless roller chain 2 is provided so as to be rotatable rightward via a vehicle or the like, and has an endless roller chain 2 having a projection member 3 capable of engaging a coil spring W in the first guide rail 1. At the right end of the first guide rail 1, there is provided a second guide rail 4 inclined in a downward slope to the right, with the left end connected to the right end of the first guide rail 1, and the second guide rail 1 An induction wheel mechanism 5 is arranged below the right end of 4.

As shown in FIG. 2, the guided vehicle mechanism 5 includes a guide drum main body 6 having a V-shaped groove formed on the outer peripheral surface thereof, and a rotary shaft 7 extending through the guide vehicle main body 6 in the left-right direction. A pair of bearings 8 which are fixedly arranged to rotatably hold the rotating shaft 7, and a reduction gear whose fixedly arranged output shaft is connected to the left part of the rotating shaft 7 via a shaft joint 9. It is composed of an attached motor 10. Then, as shown in FIG. 1, the right end of the second guide rail 4 faces the upper left side of the guided vehicle body 6 of the guided vehicle mechanism 5. In the vicinity of the right side of the guided vehicle main body 6, a chute 11 that is inclined downward in the right direction is arranged with its left end facing the upper right side of the guided vehicle main body 6, and near the right end of the chute 11 a chain A conveyor 12 is provided.

With such a structure, the endless roller chain 2 is rotated to the right, and at the same time, the motor 10 with a reducer of the guide vehicle mechanism 5 is driven to move the guide vehicle main body 6 to the endless roller chain 2 When a predetermined coil spring W is supplied into the first guide rail 1 from the other end side of the first guide rail 1 in a state of being rotated clockwise at a speed faster than the rotation of the end roller roller 2 The projecting member 3 is pulled and moved to the right, and shot from a shot projection device (not shown) for shot peening, and then sequentially moved on the first guide rail 1 and the second guide rail 4, and thereafter. Then, it is discharged from the right end of the second guide rail 4 into the V-shaped groove of the guide car body 6 so as to fall by its own weight.

The coil spring W discharged from the right end of the second guide rail 4 is forced by the induction vehicle body 6 because the traveling speed of the induction vehicle body 6 due to rotation is faster than the rotation speed of the endless roller chain 2. It is guided as if it is sent to the chute 11. As a result, the coil spring W is smoothly guided to the chute 11 and then fed onto the chain conveyor 12 via the shoot 11. The first guide rail 1 and the second guide rail 4 may be integrally provided. Further, it is not necessary to provide the V groove on the outer peripheral surface of the guided vehicle body 6.

[0010]

[Effect of device]

 As is clear from the above description, in the present invention, the guide wheel mechanism having the guide wheel main body capable of imparting the moving speed higher than the moving speed of the roller chain to the coil spring is arranged below one end of the guide rail. It is possible to guide the coil spring discharged from the guide rail after being pulled and moved on the guide rail by the roller chain to the chute at a speed faster than the moving speed on the guide rail. Is moved in the longitudinal direction of the coil spring.Even if the speed of the coil spring is relatively high or the length of the coil spring is relatively long, the coil spring on the guide rail can be smoothly discharged from the guide rail to the predetermined position. It has excellent practical effects such as being able to send it out accurately.
