Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fiber winding machine having a plurality of winding spindles and a rotor supporting the winding spindles.

[0002]

2. Description of the Related Art A glass fiber winding machine shown in FIG. 4 has a pair of winding spindles 100 and a winding spindle 1.
00 and a support block 113 on the machine base 101.
A rotor 102 that is rotatably supported via a winding spindle 1.
The position 00 can be changed between the winding position and the replacement position. In the exchange position, the tube is attached to and detached from the winding spindle 100, and in the winding position, the fiber is wound on the tube.

The rotor 102 is connected to a drive source such as a motor via, for example, a chain winding transmission mechanism, and the positioning mechanism 103 enables circumferential positioning. That is, a pair of stoppers 104 are attached to the rotor 102 at positions separated by 180 ° in the circumferential direction, and a fluid pressure cylinder 105 is attached to the machine base 101 on the shaft 1.
Cylinder 10 that is rotatably attached to the center of the cylinder
The lever 106 is attached to the telescopic rod 5 so as to be rotatable relative to the center of the shaft 107.
Is rotatably mounted on the shaft 108. Further, a stopper receiver 109 is rotatably attached to the machine base 101 about a shaft 110, and is pressed against a block 112 fixed to the machine base 101 by a spring 111. In the extended state of the illustrated cylinder 105,
The protrusion 106a formed on the lever 106 presses the stopper receiver 109 against the block 112, and the roller 106b attached to the lever 106 presses the stopper 104 against the stopper receiver 109 to position the rotor 102.

To reverse the rotor 102 by 180 ° from the above state, first, the cylinder 105 is contracted and the lever 1 is rotated.
The pressing of the stopper receiver 109 and the stopper 104 by 06 is released. Next, the rotor 102 is rotated by about 180 ° by the power of the drive source and stopped. Next, the cylinder 105 is extended to extend the roller 106 of the lever 106.
The stopper 104 is pushed by b to rotate the rotor 102, and the protrusion 106a of the lever 106 pushes the stopper receiver 109 against the block 112. Then, the stopper 104 is pressed against the stopper receiver 109, so that the rotor 102 is inverted 180 ° and positioned.

[0005]

In the reversing process of the rotor 102, it is necessary to rotate the rotor 102 close to 180 ° and then stop it. Therefore, conventionally, a motor with a brake or the like is used as a drive source of the rotor 102, and the driving force thereof is transmitted to the rotor via a chain winding transmission mechanism or the like. That is, the rotor 1 is provided on the drive side of the transmission mechanism.
No. 02 braking device is provided, and the braking force is applied to the rotor 102 via the transmission mechanism to stop the rotor 102 at a position suitable for positioning by the positioning device 103.

However, if a braking device is provided on the drive side of the transmission mechanism, the inertial force of the heavy rotor acts on the transmission mechanism during braking. For this reason, the transmission mechanism is damaged by impact, and particularly when the chain winding transmission mechanism is used, a bouncing phenomenon occurs in which the rotor vibrates due to expansion and contraction of the chain, which adversely affects the winding state of the fiber and the control of the rotor stop position. There's a problem.

It is also known that the rotor 102 is naturally stopped without providing a braking device.
In some cases, the position of the rotor 102 cannot be positioned by the positioning device 103 because the stop position is not fixed due to a change in the lubrication state of the supporting portion.

It is an object of the present invention to provide a fiber winding machine that can solve the above-mentioned problems of the prior art.

[0009]

A feature of the present invention is that a rotor is rotatably supported by a machine base and can be positioned in the circumferential direction, and a plurality of windings rotatably supported by the rotor. In a fiber winding machine including a spindle and a transmission mechanism that transmits a driving force from a drive source to the rotor, a braking device for the rotor is provided on the driven side of the transmission mechanism.

[0010]

According to the structure of the present invention, since the rotor braking device is provided on the driven side of the transmission mechanism that transmits the driving force from the drive source to the rotor, the inertial force of the rotor is transmitted to the transmission mechanism during braking. Can be prevented.

Next, the positioning of the rotor 3 by the positioning mechanism 103 is released, the rotor driving motor 28 is rotationally driven, and this driving force is transmitted via the chain winding transmission mechanism 29, whereby the rotor 3 starts reversing. .. Then, when the rotor 3 is inverted by approximately 180 °, the sensor 41 detects the dog 40, the detection signal stops the rotor driving motor 28, and the braking device 35 is activated for a certain period of time to apply a braking force to the rotor 3.
