Abstract

(57) [Summary] [Purpose] Install the hanger stop micro switch in the hanger rail without causing false detection due to hanger roll and overload of the micro switch. [Structure] A micro switch 3 is arranged inside or below a position where a hanger needs to be stopped, and an actuator 5 of the micro switch 3 is projected from the upper surface to the outside and above.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rail of a hanger transporting device that transports a hanger on which a sewing material is hooked, along a sewing machine dedicated to each sewing part.

[0002]

[Prior Art]

 To stop the hanger at the position of the sewing machine dedicated to each sewing part and perform the necessary sewing with that sewing machine, you must operate the hanger lifting device to carry the hanger from that position to the sewing position of the next process. I have to. Conventionally, in order to send the stop or operation signal, the micro switch 3 is arranged on the outer surface of the square rail 1 as shown in FIG. 3, and the round rail 1 of the round rail 1 as shown in FIG. A micro switch 3 is provided on the outer side surface, and a plate-like actuator 5 is arranged slightly above the micro switch 3, for example. When the outer periphery of the hanger roller 6 touches the microswitch 3 or the actuator 5, the movement of the hanger to that position is detected.

[0003]

[Problems to be solved by the device]

 In any of the above, even if the hanger sways and inclines slightly as shown by the alternate long and short dash line, the outer periphery of the roller 6'of the hanger separates from the microswitch 3 or the actuator 5 and does not touch the microswitch 3. Therefore, the movement of the hanger to that position is not detected, and the false detection rate is high. Also, when the micro switch 3 is tilted in the opposite direction, the micro switch 3 becomes overloaded, which causes a failure of the micro switch 3.

An object of the present invention is to provide a rail incorporating a hanger detection microswitch in a state in which erroneous detection due to rolling of the hanger and overload of the microswitch do not occur.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the hanger rail of the present invention has a microswitch disposed inside or below a position where detection of the hanger is required, and the actuator of the microswitch is projected from the upper surface to the upper outside. ..

[0006]

[Work]

 In the hanger rail configured as described above, the hanger moves to the position where the microswitch is arranged while swinging laterally on the rail. However, the roller shaft of the hanger moves only upward, and the microswitch is not overloaded. Moreover, the upward displacement of the central portion of the roller shaft that comes into contact with the actuator is extremely small, and the malfunction of the microswitch does not occur. When the micro switch is turned on, normal operation is obtained and the hanger can be detected.

[0007]

【Example】

 The hanger rail of the present invention will be described with reference to FIGS. 1 and 2.

The hanger rail 1 has a microswitch 3 arranged via a bracket 2 inside a position where the hanger needs to be detected.

The rail 1 may be a square type or a round type, and a micro switch 3 is fixed to a bracket 2 inside the rail 1 by bolts 4 or the like. As shown in FIG. An elongated hole 1a is formed on the upper surface at a position corresponding to the upper side of 3.

A plate-shaped actuator 5 is provided above the micro switch 3 so as to project upward from the elongated hole 1 a of the rail 1 to the outside. In this actuator 5, the central flat portion projects to the uppermost side, and the front and rear sides thereof have a gentle slope. When the outer periphery of the shaft 7 of the hanger roller 6 touches the actuator 5 and pushes it down, the micro switch 3 is turned on, and the movement of the hanger to that position is detected. In addition, 8 is an arm of a hanger.

Although the hanger moves on the rail 1 while swinging laterally, the hanger is inclined at one of the corners of the upper part of the rail 1 as a fulcrum at the position of the actuator 5 as shown by the one-dot chain line in FIG. However, since the shaft 7 of the hanger always moves only upward, the microswitch 3 is not overloaded. Moreover, since the position of the shaft 7 touching the actuator 5 is in the vicinity of the center, the upward displacement of the hanger due to the lateral shake of the hanger is significantly larger than that of the conventional one in which the roller 6 operates the micro switch 3. The size of the micro switch 3 is reduced, and the malfunction that the micro switch 3 is turned off when it should be turned on is eliminated.

In the above, an example in which the microswitch 3 is housed in the rail 1 and the actuator 5 thereof is projected above the rail 1 has been described. However, in addition, the microswitch 3 is arranged below the rail 1 and has a rod shape. The linear actuator may pass through the rail 1 from above the microswitch 3 and project upward.

[0013]

[Effect of the device]

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

That is, even if the hanger shakes sideways at the position of the micro switch and tilts, the axis of the hanger always moves only upward, and the displacement of the central part is very small. Almost no overload occurs. Also, if the micro switch is built into the rail, it has a good appearance and can prevent damage to the micro switch due to contact with other things.
