Description

Description: TECHNICAL FIELD The present invention relates to a device for manufacturing a grooved interposer core optical cable by dropping a tape core wire into a groove of a grooved interposer core, and more particularly to a tape core wire with a groove The present invention relates to an improvement in a tape core wire rotating type grooved interposer core optical cable manufacturing apparatus for manufacturing an optical cable by feeding the interposer core while rotating around the axis of the traveling path of the interposer core and dropping it into the groove of the interposer core with grooves.

(Prior Art) Generally, a tape core wire rotating type grooved intervening core optical cable manufacturing apparatus is a tape core wire that is fed while rotating from the rotating gauge around the axis of the grooved interposing core through the center of the grooved interposing core. The assembly die that drops the grooved interposer core into the grooved interposer core, the take-up machine that takes in the grooved intervening core optical cable formed by dropping the tape core wire with the collective die, and the take-up speed of this take-out machine of the tape core wire. And a take-up machine control means for controlling according to the rotation speed. In this type of optical cable manufacturing apparatus, if the groove pitch of the grooved interposing core is deviated, the tape core wire cannot be dropped into the groove of the grooved interposing core.
It is necessary to displace the assembly die or change the take-up speed of the grooved interposer core so that the drop of the tape core wire matches the groove position of the grooved intervening core. Must be done with high responsiveness. In the conventional technique, the position of the collecting die is displaced in the axial direction of the grooved interposing core with the manual handle to correct the groove deviation, and when the displacement of the collecting die cannot be corrected, the differential gear of the take-up machine is manually operated. The handle was displaced to correct the take-up speed so that the tape core wire was reliably dropped into the groove of the interposing core.

However, in such a conventional technique, since the deviation of the groove of the interposing core is visually judged, the fatigue of the operator is increased and an erroneous judgment may occur, and the position of the assembly die and the take-up of the take-up machine are taken. Since the speed is manually adjusted, the workability is poor and the productivity is low.

(Object of the Invention) An object of the present invention is to provide an apparatus for manufacturing a grooved interposer core optical cable capable of automatically detecting the deviation of the groove position of the interposing core and automatically correcting the deviation with high responsiveness. To provide.

(Structure of the Invention) A manufacturing apparatus for a grooved interposer core optical cable according to the present invention is
An assembly die that drops a plurality of tape core wires fed from a rotating gauge that rotates around the axis of the grooved intervening core into the plurality of grooves of the grooved intervening core, and the tape core wire thus drops. Of a grooved interposer core optical cable provided with a take-off machine for taking the grooved interposer core optical cable formed by being inserted and a take-up machine control means for controlling the take-up speed of the take-out machine in accordance with the rotation speed of the rotation gauge In the manufacturing apparatus, a die displacement means for displacing the collective die in the axial direction of the grooved interposing core, a groove position detector for detecting the groove position of the grooved interposing core, and a groove position signal supplied from the groove position detector. And a groove position setting signal from the groove position setter to output a displacement signal corresponding to the displacement amount of the groove position of the interposer core with grooves, and a die change signal corresponding to the displacement signal from the comparator. Further comprising a control unit for controlling the means, the control unit including activating means for activating the puller control means in response to a critical signal from a critical position detector for detecting a control critical position of the die displacement means. Is characterized by.

With this configuration, the deviation of the interposition core groove position is automatically detected, the position of the assembly die is automatically corrected according to the deviation of the interposition core groove position, and the position of the assembly die can be corrected. If it exceeds the above range, the take-up speed of the take-up machine is automatically corrected according to the deviation of the groove position of the grooved interposition core. The collective die is lighter than the take-up machine and can be displaced with high responsiveness. Therefore, first, the position where the tape core wire is dropped into the groove of the grooved interposing core by the displacement of the highly responsive collective die. When the modified die reaches the control critical position where the displacement of the assembly die reaches its limit, the take-up speed of the take-up machine, which is unavoidably heavy and has low responsiveness, is controlled. It can be corrected with high responsiveness. Therefore, the grooved interposer core optical cable can be manufactured with high productivity.

(Example) An example of the present invention will be described in detail with reference to the drawings.
FIG. 1 shows a manufacturing apparatus 10 for an intervening core optical cable with grooves according to the present invention.

A pulling machine 22 for pulling the grooved interposer core optical cable 20 formed by dropping the tape core wire 16 and a constant rotation speed N of the rotary cage 14 for feeding the tape core wire 16 from the pulling speed V of the pulling machine 22. In accordance with pN = V (where p is the grooved intermediate core 12
(Representing the pitch of the groove), and a take-up machine control means 24. The rotating cage 14 is rotated from a main motor 26 via a cage transmission mechanism 28, and the take-up machine 22 is driven from the main motor 26 via a take-up machine transmission mechanism 32 including a transmission 30 and a take-up machine control means 24. . The take-up machine control means 24 includes a differential gear 34 connected to the line shaft 32a of the take-up machine transmission mechanism 32, and the position of the differential gear 34 is displaced to control the take-up speed of the take-up machine 22.

In the manufacturing apparatus 10 of the present invention, the assembly die 18 is provided with a grooved interposing core.
Die displacing means 36 that is displaced in the axial direction of 12, groove position detector 38 that detects the groove position of grooved interposition core 12, groove position signal Sp supplied from this groove position detector 38, and groove position setter
Comparing with the groove position (pitch) setting signal Ss from 40, it outputs a displacement signal Sd corresponding to the displacement of the groove position of the grooved interposition core 12, and a comparator 42 corresponding to the displacement signal Sd from this comparator 42. Further, a control unit 45 for controlling the die displacement means 36 or the take-up machine control means 24 is further provided. The groove position detector 38 detects the position of the groove by electrically converting the displacement of the arm engaged in the groove of the grooved interposition core 12 with the potentiometer 38A, for example (see FIG. 2). In FIG. 1, reference numeral 38B is a slip ring for supplying the groove position signal Sp from the potentiometer 38A to the comparator 42. As shown in FIG. 2, the groove position setter 40 is composed of a potentiometer and displaces the wiper 40a to obtain a set signal of a predetermined groove position (groove pitch).

The take-up machine control means 24 has a DC servo motor 44 that displaces the differential gear 34, and this servo motor 44 is driven by a servo drive unit 46. Also, die displacement means
36 comprises a feed screw 52 which is threaded through a screw cylinder 50 attached to the lower end of a support rod 48 which supports the assembly die 18, the feed screw 52 is connected to a pulse motor 54, and the pulse motor 54 is a motor drive unit. Driven by 56.

The difference signal Std from 66 is supplied to the dead zone amplifier 60, and this dead zone amplifier 60 generates an output (critical signal) when the difference signal Std exceeds the dead zone and drives the servo drive unit 46. This dead zone is a range in which the feed screw 52 is screwed into the screw cylinder 50 and the displacement of the groove of the grooved interposition core 12 can be processed by the feed screw 52.
Therefore, if the difference signal Std exceeds this dead zone, it means that this displacement cannot be corrected by the feed screw 52. That is, the dead zone amplifier 60 functions as a critical position detector that detects the control critical position of the die displacement means 36.

The motor drive unit 56 drives the pulse motor 54 by the output from the comparator 42, and the assembly die 18 is immediately displaced in the axial direction in accordance with the displacement of the groove by the rotation of the feed screw 52, and the tape core wire 16 of the grooved intermediate core 12 is moved. Make sure it falls into the groove. In addition, the displacement of the groove is
If it exceeds the range that can be corrected by, the difference signal Std exceeds the dead zone of the dead zone amplifier 60, so the servo drive unit 46 drives the servo motor 44 to 0, displaces the differential gear 34 of the take-up control means 24, and the take-up machine 22.

In the present invention, when the take-up speed of the take-up machine 22 is controlled after the displacement of the collecting die 18, the responsiveness of the correction of the groove position of the grooved intermediate core can be improved. That is, grooved interposer core
In order to correct the misalignment of the groove position of 12, the lightweight and low momentum assembly die 18 is first displaced, and when the displacement of this assembly die 18 reaches the limit, there is unavoidable weight and response. By controlling the take-off machine 22 having low property, the control response can be enhanced as much as possible.
