Description

BACKGROUND AND OBJECTS OF THE INVENTION The present invention relates to a fixed position correction device for a rotating cage of a wire twisting machine.

FIG. 1 shows a conventional example of a stranded wire winding section of a double stranding machine. As shown in the figure, a rotating cage 3 supported by support frames 1 and 1a via bearings 2 and 2a is rotated about an axis X-X by a motor (not shown). . A pair of bobbin device spindles 6, 6a are attached to the cradle 5, which is supported via inner bearings 4, 4a of the rotation cage 3, facing each other in the axis Y-Y direction. Spindle 6 for bobbin installation,
Among the spindles 6a, one spindle 6 is attached to the cradle 5 via a bearing 7, and the other spindle 6a moves back and forth with respect to the paired spindle 6, thereby moving the bobbin 8 relative to the cradle 5. Installation and removal are performed. In the figure, numeral 9 denotes a bobbin drive motor for winding the stranded wire onto the bobbin 8. The stranded wire 10 in the cradle 5 is wound several times around the take-up pulley 11 and the guide pulley 12, and then the stranded wire 1
It passes through the dancer guide pulley 14, which expands and contracts between the pulleys and the guide pulley 13 with zero tension, is folded back at the guide pulley 15, passes through the traverser guide pulley 17 connected to the driver shaft 16, and is wound onto the bobbin 8. .

When replacing the bobbin 8 for which work has been completed with an empty bobbin, an elevating device that moves on the open lower side of the cradle 5 is used. In this case, if the rotating cage 3 were located between the lifting device 18 and the bobbin 8 as shown in FIG. 2, not only would the lifting device 18 not be able to fulfill its purpose, but also Damage cage 3. To prevent this, before bringing the lifting device 18 close to the cradle 5, manually move the rotating cage 3 to the normal position (appropriate position) as shown in FIG. I had adjusted it so that it was out of the way. By the way, in order to automatically straighten the rotating cage 3 in order to improve the efficiency of this type of work, it is necessary to add special electric control for straightening to the drive source (not shown) that drives the rotating cage 3, or to use a separate motor. It is necessary to install a clutch mechanism and a clutch mechanism, but the former lacks precision and the latter is expensive.

The present invention has been made in view of the above points,
It is an object of the present invention to provide a fixed position correction device for a rotating cage of a wire twisting machine, which enables the rotating cage to be reliably and easily corrected to a fixed position.

[Summary of the Invention] That is, the present invention provides a rotary cage that is supported by a support frame and is rotatably driven via a drive motor and a drive shaft connected to the drive motor, and is capable of replacing a bobbin on which a stranded wire is wound. In a fixed position correcting device for a rotating cage of a wire twisting machine, the fixed position correcting device is connected to a ratchet gear attached to the drive shaft, and a rotation mechanism that rotationally drives the rotating cage via the ratchet gear. The rotary cage is characterized by comprising a cage drive device and a rotary cage position sensing device that senses the fixed position of the rotary cage, whereby the rotary cage is connected to the ratchet gear, the rotary cage drive device, and the rotary cage. The position sensing device will correct the position.

[Example] The present invention will be described below based on the illustrated example. An embodiment of the present invention is shown in FIGS. 4-6. Note that parts that are the same as those in the conventional system are given the same reference numerals, and therefore their explanations will be omitted. In this embodiment, the fixed position correction device for the rotating cage 3 is connected to a ratchet gear 21 attached to a drive shaft 20 connected to a drive motor 19 for driving the rotating cage 3, and a ratchet gear 21 for controlling the rotating cage 3 via the ratchet gear 21. It is composed of a rotating cage driving device that rotates and a rotating cage position sensing device that detects the fixed position of the rotating cage 3. By doing this, the rotating cage 3
The fixed position correction device includes a ratchet gear 21 attached to a drive shaft 20, a rotary cage drive device that rotationally drives the rotary cage 3 via the ratchet gear 21, and a rotary cage position that senses the fixed position of the rotary cage 3. The rotating cage 3 includes a ratchet gear 21, a sensing device, and a sensing device.
Correcting the rotating cage of a wire twisting machine into a fixed position by using a rotating cage driving device and a rotating cage sensing device, and making it possible to reliably and easily correct the rotating cage 3 into the fixed position. You can get the equipment.

That is, the device for correcting the fixed position of the rotating cage 3 is composed of a ratchet gear 21, a rotating cage driving device, and a rotating cage position sensing device, but the rotating cage driving device is composed of an air cylinder 23 equipped with a pawl 22 that meshes with the ratchet gear 21. . Then, attach this air cylinder 23 with a claw 22 at its end.
A piston 24 having a fixed piston 24, a piston outlet air pipe 25 and a piston return air pipe 26 for supplying air for moving the piston 24 in and out, are provided, and are supported on a pedestal 27 via a clevis 28 and a stopper 29, In addition, the piston 24 is configured to move up and down at a height above the stopper 29 on the inlet and outlet sides. In addition, the rotating cage position sensing device,
The metal piece 30 provided on the rotating cage 3 and the support frame 1a
a proximity switch 31 that is fixed to the rotary cage 3 and senses and reacts to the metal piece 30 when the rotating cage 3 reaches the home position;
It was composed of By doing so, the results can be achieved as described below.

When the wire stranding work has been completed and the rotating cage 3 is to be corrected to its proper position in preparation for replacing the bobbin 8 on which the stranded wire 10 has been wound, the procedure as shown in FIG. Intermittent electric signals, that is, cylinder output and cylinder return signals, are sent to the piston output air pipe 25 that supplies output air to the piston 24 of the air cylinder 23 and the piston return air pipe 26 that supplies return air. It is applied to a solenoid valve (not shown) that switches the air. This causes the piston 24 of the air cylinder 23 to reciprocate. This reciprocating motion causes the pawl 22 to rotate the ratchet gear 21 in the direction indicated by the arrow in the figure, thereby causing the drive shaft 20, the drive pulley 32 connected to the drive shaft 20,
32a, the rotating cage 3 is rotated via transmission belts 33, 33a, one end of which is connected to the driving pulleys 32, 32a, and driven pulleys 34, 34a, which are connected to the other end of the transmission belts 33, 33a. I am made to do so. The reciprocating movement of piston 24 continues until proximity switch 31 is actuated. When the proximity switch 31 operates, the piston 24 returns, the connection between the pawl 22 and the ratchet gear 21 is released, and the rotating cage 3 is corrected to the proper position. The side of the air cylinder 23 opposite the piston 24 is fixed to the mount 27 using the clevis 28 as described above, so the air cylinder 23 does not move back and forth, or the piston 24 side moves up and down around the clevis 28. Let's do it. Therefore, the stopper 29 is fixed to the frame 27, the piston 24 is kept above a certain height, and the pawl 22 and the ratchet gear 21 are smoothly engaged. As described above, according to this embodiment, there is no need to separately provide a motor for correcting the position of the rotating cage 3 or a clutch mechanism, so that the cost is low. Also, no maintenance is required.
And it has good accuracy. These features make it possible to automatically correct the rotating cage 3 to the proper position when replacing the winding bobbin of the wire stranding machine.

In this embodiment, the position of the rotating cage is sensed using a nearby switch, but the present invention is not limited to this, and a photoelectric switch may be used instead.

Further, although the air cylinder is configured to mesh with the ratchet gear when the piston is moved out, the air cylinder may be configured to mesh with the ratchet gear when the piston is moved in (returns).

Furthermore, in this embodiment, the lifting device is applied from below, but it can also be used from above.

[Effects of the Invention] As described above, the present invention provides a twist system that enables the rotating cage to be reliably and easily corrected in the normal position. A fixed position correction device for a rotating cage of a line machine can be obtained.
