DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hanger transfer device for transferring hangers to a stepped transfer path.

[0002]

2. Description of the Related Art FIG.
As shown in FIG. 1, a first rail 1 and a second rail 2 are connected by a rail 3, and an arm 4 that moves in parallel along the rail 3 is supported by a guide portion 5. There has been proposed a device which is moved and is transported by hooking a wheel 9 of a hanger 8 by a claw 7 provided at a tip of an arm 4.

FIG. 4 shows another hanger transport device.
As shown in FIG. 1, a chain 11 driven by a motor 10 along a rail 3 is provided, and a wheel 8 of a hanger 7 is hooked and transported by a claw 12 fixed to a part of the chain 11. ing.

[0004]

However, in such a hanger transport device, the one shown in FIG.
Guide part 5 for moving arm 4 in parallel with rail 3
In addition, the claw 7 provided at the tip of the arm 4 is retracted when it hits the wheel 9 of the hanger 8, and a movable type that protrudes beyond the wheel 9 is required. And the transport direction is the second rail 2
Is not the same as the transport direction of the first rail 1
From the second rail 2 cannot be quickly conveyed.

In the hanger transfer device shown in FIG. 4, the tension of the chain 11 needs to be adjusted, and the structure is complicated.
And the transport direction is the same as the transport direction of the second rail 2.
Can not be transported quickly because they are not the same
There was a problem.

[0006]

According to the present invention, there is provided a first transport path which is inclined downward as it advances in the transport direction, and a starting end located at a position above the end of the first transport path and spaced apart in the transport direction. The second is inclined downward as it moves in the transport direction.
And a transport path for transporting the hanger from the first transport path to the second transport path, wherein the base end is rotatably supported and the distal end is the second transport path from the end of the first transport path. An arm rotatably moving at the start of the transport path, a claw provided at the tip of the arm and forming a forked shape, and a tip of the arm
Is located at a predetermined distance from the rotation locus in the circumferential direction
A guide that engages with the hanger when the pawl is located at the end of the first transport path, holds the hanger during rotation of the arm, and moves the hanger to the second transport when it is located at the end of the second transport path. This is to solve the above-mentioned problem by sending the paper on the road and in the transport direction of the hanger.

[0007]

According to the present invention, the hanger sent to the first transport path is held by the stopper and waits. Here, the tip of the arm is waiting below the stopper, and when the arm rotates, the wheel of the sent hanger is placed on the claw .
And guides the protrusion from the nail due to the centrifugal force of rotation.
The sheet is transported to the second transport path while being prevented .

[0008] The tip of the hanger moves to the second transport path and is sent out. Thereby, the wheels of the hanger are urged by the rotation of the arm and vigorously roll on the second transport path. Then, the tip of the arm returns to below the position of the stopper on the first transport path by the cylinder.
When the next hanger is waiting at the position of the stopper on the transfer path, the arm wheel is pushed back by the claw at the tip of the arm, and the arm moves below the stopper.

If the hanger is continuously fed while the hanger is being moved by the arm, the drive shaft of the retraction cylinder protrudes and engages with the subsequent hanger and does not pass.

[0010]

FIG. 1 is a front view of a hanger transport device according to an embodiment of the present invention. A first transport path 13 is supported on a support 12 and a stopper 14 is provided at the end of the first transport path 13. The first transport path 13 is fixed, and the second transport path 1 is
5 is supported by a support 12.

Further, one end of an arm 17 is rotatably supported by a fulcrum 16 below the start end of the second transport path 15, and further, a bifurcated claw 18 is formed on the top end of the arm 17.
The arm 17 is configured such that the claw 18 is
It extends to be located in the part. In addition, arm 1
A drive shaft 21 of a cylinder 20 is rotatably mounted on a fulcrum 19 provided at the center of the cylinder 7, and the cylinder 20 is rotatably supported by a support 12 at a fulcrum 22.

In this embodiment constructed as described above, when the cylinder 20 is driven, the arm 17 is rotated by the drive shaft 21, and at that time, the hanger is sent to the stopper 14 of the first transport path 13. The shaft portion of the wheel 24 is moved on the claw 18 of the arm 17. When the claw 18 of the arm 17 moves to the start end of the second transport path 15, the wheels 24 of the hanger 23 move onto the second transport path 15 with the turning force of the arm 17 and move thereon. .

Thereafter, the claw 18 at the tip of the arm 17 returns to below the stopper 14 of the first transport path 13 by the extension of the drive shaft 21 of the cylinder 20, and the next hanger 23
Wait until the message is sent. When the arm 17 returns, the hanger 23 moves to the stopper 14 of the first transport path 13.
When the arm 17 is on standby, the arm 17 pushes the wheel 24 of the hanger 23 back and moves downward.
Has an arcuate guide surface formed at the tip of the.

As described above, in this embodiment, the cylinder 20
The hanger 23 can be transported from the first transport path 13 to the second transport path 15 with a simple configuration for rotating the arm 17 with no need to drop oil or provide a rotating claw. When the hanger 23 is sent, the first transport path 13
When the wheel 24 of the hanger 23 hits the stopper 14 and returns, the hanger 23
A return prevention plate 25 for preventing return of the wheels 24 may be provided.

In order to prevent the hanger 23 from jumping out when the arm 17 is rotated, a return prevention plate 25 is provided.
From the position of the second conveyance path 15 to the beginning of the second conveyance path 15
Is provided. When the hanger 23 is continuously sent, the hanger 23 is moved to the retraction cylinder 27,
What is necessary is just to send sequentially by 28.

FIG. 2 is an explanatory view of a device for operating the cylinder 20 and the retraction cylinders 27 and 28 of the hanger transport device according to the embodiment of the present invention. The solenoid valve 29 is connected to a fluid path connected to a fluid source. 30, fluid passages 31 and 32 connected to the cylinder 20, and fluid passages 33 and 34 connected to the retraction cylinders 27 and 28. Further, a first limit switch 35 is mounted on the support 12 below the retraction cylinders 27 and 28, a second limit switch 36 is mounted on the cylinder 20, and a third limit switch 36 is mounted on the second transport path 15.
Is mounted.

In this device, the third limit switch 3
7 is off, the first limit switch 35 is on, and the second limit switch 36 is on, the hanger 23
At both the position of the stopper 14 and the retracted position,
By driving the solenoid valve 29, the cylinder 20 and the retraction cylinder 2
When the members 6 and 27 are driven, the hanger 23 is sent to the second conveyance path 15 by the claws 18 of the arm 17.

At the same time, the retracting cylinders 27, 2
8 is driven to feed the hanger 23 to the position of the stopper 14. The cylinder 20 is driven, and the claw 1 at the tip of the arm 17 is moved.
8 moves to the start end of the second transport path 15 and the second transport path 1
The hanger 23 is sent to the third limit switch 3
7, the electromagnetic valve 29 is turned off, and the arm 1
7 is returned to the original position.

[0019]

As described above, in the hanger transport device of the present invention, the base end is pivotally supported rotatably, and the tip end is the first end.
An arm rotatably moving from the end of the transfer path to the start end of the second transfer path , a claw provided at the end of the arm and forming a bifurcated shape, and a predetermined distance in a circumferential direction from the rotation locus of the end of the arm
Since it is equipped with a guide arranged at a separated position ,
The hanger conveyed by the claw is the centrifugal force of the rotation of the arm.
After the work is finished, the hanger can be quickly conveyed to the next process after the work is completed because the hangers are sent out to the second conveyance path while being prevented from protruding from the claw by the guide , and vigorously roll on the second conveyance path. .
