The position of the spiral groove of this wire body 1 is detected by the position detector 17 and the control part 18 drives a change speed gear 5 according to the detected value to control the rotating speed of the takeup machine 3 and control the driving of a motor 9 for driving; and a slide base 7 is moved and adjusted in the lengthwise direction of the wire body 1 to hold the position relation between the spiral groove of the wire body 1 and cable insertion part constant.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cable insertion device into a striatal helical groove;
In particular, the present invention relates to a device used in manufacturing an optical fiber tape unit and an 0PGW (overhead ground wire with optical fiber) optical unit.

[Prior Art] Generally, when manufacturing an optical fiber tape unit or an optical unit of oPGW, etc., a cable such as an optical fiber or an optical unit is placed along the outer periphery of a filament to integrate them. However, in order to make the integration more solid, a method is sometimes adopted in which spiral grooves with a constant pitch are provided on the outer periphery of the filament and the cable is inserted into the spiral grooves.

In this case, the wire body provided with the spiral groove was rotated and moved from the sending device to the take-up device, and during this time the cable was inserted into the spiral groove through the battens, but this work was not done by the operator. This was done while being supervised.

Here, since the spiral grooves of the filament are provided at a constant pitch, if the filament is moved while simultaneously rotating the sending device and the winding device according to the pitch, the helical groove will be placed on the ground. It appears to be stopped against. In this state, the cable is inserted from the fixed cable feeder into the helical groove through the fixed batten.

However, in reality, it is difficult to form the spiral grooves of the filament at a perfectly constant pitch, and errors may occur. For this reason, the helical groove does not completely stop with respect to the ground and rotates gradually, making it impossible to insert the cable into the helical groove through the fixed batten.

Therefore, the operator constantly monitors the cable insertion part and adjusts the relationship between the rotation of the delivery device and winding device and the movement of the wire body if the batten and the filament body deviate beyond the allowable range. was. Specifically, these devices were stopped and the conduction system was temporarily disconnected to correct the positional relationship of each device, and for further fine-tuning, multiple battens were moved in the longitudinal direction or rotational direction of the striatum. Was.

[Problems to be Solved by the Invention] As described above, in the past, there was a problem in that manual labor was always required to insert the cable into the spiral groove of the filament, and this also led to a reduction in work efficiency.

Thus, an object of the present invention is to solve the problems of the prior art described above and to provide a device for inserting a cable into the spiral groove of a filament body, which can automatically and efficiently insert the cable into the spiral groove without the need for human intervention. It's about doing.

[Means for Solving the Problems] In order to achieve the above object, the device for inserting a cable into the spiral groove of the filament body according to the present invention is designed such that the helical groove provided on the outer periphery of the filament body appears stationary. In a device for moving a filament in the axial direction while rotating the filament, the filament is introduced into a cable insertion part, and the cable is inserted into the helical groove at the cable insertion part. a position detector for detecting the position of the helical groove in the body; and a position detector for positioning the helical groove in the filament body at a predetermined position with respect to the cable insertion portion based on the position of the helical groove detected by the position detector.
and a control section that adjusts the rotational speed or moving speed of the filamentous body and moves the cable insertion portion relative to the filamentous body so as to maintain the cable insertion portion.

[Function] The spiral grooves of the striatum are normally formed at a constant pitch, but errors inevitably occur in this pitch, so if the striatum is rotated at a constant speed, the position of the helical groove can be perfectly aligned with respect to the ground. It is difficult to stop it. Therefore, by detecting the position of the helical groove of the striatum using a position detector and adjusting the rotational speed or movement speed of the striatum based on the detected value, the position of the helical groove can be kept constant. become.

However, since the filament is affected by its rigidity and other disturbances, the helical groove appears to sway somewhat in the direction of rotation. In order to cope with this wobbling, the cable insertion portion is moved in the longitudinal direction of the filament or rotated around the filament based on the detection signal from the position detector. By doing this, the positional relationship between the helical groove of the filament and the cable insertion portion is always constant b, making it possible to insert the cable into the helical groove.
