Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention is a device for pulling a hanger from a lower part to a higher part of a slant rail in a hanger transport device that circulates and transports a sewing machine dedicated to each sewing part by dropping the hanger on which the sewing material is hooked on the slant rail. It is about.

[Prior art]

 2. Description of the Related Art As a hanger pulling device for a hanger transport device, the one shown in FIG. 2 is conventionally known. 2 (1) shows a cylinder 22 having a claw 22a at its front end for pulling up the hanger roller R while rotating it along a steeply inclined conveying path 21 that connects between the gently inclined conveying paths 1. It is provided. As shown in FIG. 2 (2), the hanger roller R is pulled up by the claw 23 a fixed to the upwardly moving chain 23 provided on the steeply inclined conveying path 21 that connects the gently inclined conveying paths 1. It is a thing. As shown in FIG. 2 (3), the hanger roller R is pulled up by the rail 24 that reciprocally rotates about the upstream end of the high position of the inclined rail 1 as a fulcrum.

[0003]

[Problems to be solved by the device]

 In any of the above hanger pulling devices, no force other than the self-weight acts on the hanger roller R after being pulled up from the lower part to the higher part of the transport path 1, and the hanger unit makes a pendulum motion. At times, it may go back (in the case of the one shown in Fig. 2 (1) and Fig. 2 (2), it may fall down a steeply inclined rail) and not only cannot obtain stable operation, but also The speed at which the hanger roller R moves along the transport path 1 is not too high. 2 (1) and 2 (2), the steeply inclined conveying path 21 is raised while the hanger roller R is rolled by the pawl, so that the pulling speed is not fast.

The present invention aims to increase the transport speed of a hanger unit in a hanger transport device.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the hanger pulling device of the hanger carrier of the present invention is rotatably arranged between the lower end and the higher end of the slanted rails which are intermittently arranged, and the hanger pulling device is provided at the front end. It has a swing arm equipped with a roller hook on which the hanger roller is placed, so that the lifted hanger roller can be discharged tangentially to the high part of the inclined rail.

[0006]

[Action]

 In the hanger pull-up device of the hanger transport device configured as described above, when the hanger roller that has run from the front sewing process stops above the roller hook, the swing arm moves in an arc toward the higher side of the inclined rail. The hanger roller, while being caught by the roller hook, is rapidly accelerated in the tangential direction to the high position of the slant rail and discharged, and is conveyed to the next sewing process.

[0007]

【Example】

 With reference to FIG. 1, the hanger pulling device of the hanger conveying device of the present invention will be described.

This hanger pulling device includes a swing arm 2 rotatably arranged around a support shaft 5 between a lower end and a higher end of a gently inclined rail 1 which is intermittently arranged, and a swing arm. It comprises a roller hook 3 rotatably supported by a support shaft 6 at the tip of 2 and an actuator 4 such as an air cylinder for rotating the swing arm 2.

The actuator 4 is rotatably supported on the machine frame F by a support shaft 7, and its rod 4 a is connected to the swing arm 2 by a connecting pin 8. Therefore, the swing arm 2 can move in an arc between the standby position shown by the solid line and the discharge position shown by the chain double-dashed line.

A roller hook spring 9 is provided between the swing arm 2 and the roller hook 3, and the roller hook 3 that captures the shaft Ra of the hanger roller R is rotated counterclockwise by the roller hook spring 9. It is biased and normally abuts on a roller hook stopper 10 fixed to the swing arm 2.

An inrail 11 having a stopper 11a is connected to the lower end of the inclined rail 1, and a roller guide 12 having a step 12a is fixed to the upper surface of the inrail 11. A limit switch 13 that emits a signal for retracting the rod 4a of the actuator 4 is arranged in front of the stopper portion 11a of the inrail 11.

The stepped portion 12a of the roller guide 12 moves backward when the hanger roller R traveling on the inclined rail 1 hits the stopper portion 11a of the inrail 11 and stops due to a reaction to swing the hanger in the front-back direction. It serves as a reversion preventing means for preventing the swing arm 2 from idling without being caught by the roller hook 3.

An outrail 14 having a guide portion 14a is connected to the end of the inclined rail 1 at the high position.

Further, an arm guide 15 and a fall guide 16 for preventing the hanger unit from falling during pulling up are provided from the lower side to the higher side of the inclined rail 1. Further, a pop-out prevention guide 17 for preventing the hanger unit from popping out is provided on the operator side at the lower end of the inclined rail 1.

The fall guide 16 above the outer rail 14 is provided with a backflow stopper 18 urged to project to a position where it engages with the shaft Ra of the passing hanger roller R, and the backflow stopper 18 on the downstream side thereof is provided. The machine frame F above the fall guide 16 is urged to project to a position where it engages with the limit switch 19 that issues a signal for returning the swing arm 2 to the standby position and the outer ring Rc of the passing hanger roller R, A lever 20 for turning on and off the limit switch 19 is arranged.

In the hanger pulling device of the hanger transporting device configured as described above, the outer ring Rc of the hanger roller R that has traveled on the rail 1 from the front sewing process contacts the stopper portion 11 a of the inrail 11 and the shaft 11 Ra is positioned above the roller hook 3 and stopped, and the limit switch 13 is turned on. The signal causes the rod 4a of the actuator 4 to be retracted, so that the swing arm 2 makes an arc motion about the support shaft 8. At that time, the hanger roller R is caught by the roller hook 3 and moves upward, is discharged to the guide portion 14a of the outrail 14, and rushes in the tangential direction of the arc movement locus of the swing arm 2 until the next sewing process. Will be transported. When the hanger unit is released, the lever 20 is pushed and rotated by the outer ring Rc of the hanger roller R, and the limit switch 19 is turned on. The hanger passing signal causes the swing arm 2 to return to the lower standby position. At that time, even if the roller hook 3 hits the shaft Ra of the subsequent hanger roller R which is already waiting, the roller hook 3 rotates around the support shaft 6 as a fulcrum and counterclockwise against the force of the roller hook spring 9. You can move, so it doesn't matter.

[0017]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects.

That is, since the hanger roller is pulled up by the arc motion of the swing arm, and the hanger roller is vigorously ejected tangentially to the high position of the inclined rail, the pulling operation is fast and inertial force is applied. The moving speed of the hanger roller can also be increased. Therefore, the transportation time is shortened and the work efficiency is improved.
