Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding machine for a wire rod such as an optical fiber, and in a bobbin traverse winding machine, the bobbin flange (flange) is formed by changing the traverse width of the bobbin. ) It is possible to prevent the winding of the wire from being disturbed during the winding process. Especially, in the case of an optical fiber or an ultra-fine wire, it is desirable to avoid applying excessive force such as twisting to the wire during winding or drawing. It is effective when used for a winder.

[0002]

2. Description of the Related Art As a method of winding a wire material such as an optical fiber ribbon on a bobbin, there are a traverse method in which a traverser for guiding the wire material to the bobbin reciprocates left and right, and a bobbin traverse method in which the bobbin reciprocates left and right. There is. In the latter winding method, a method is used in which the stroke end of the bobbin is detected by a limit switch and the detection signal is used to reverse the stroke direction of the bobbin, that is, the traverse direction. In this conventional method, the reversal positions at two points on the left and right in the traverse direction are manually set based on the width between the brims of the bobbin, that is, the width of the bobbin, and the adjustment is repeated manually. When this method is used, the bobbin width may not be constant due to bobbin manufacturing errors, and manual adjustment may not be accurate. It is not possible to reverse the traverse position, which often results in winding disturbances. This winding disorder occurs because the timing of reversal of the traverse direction is missed. This winding disorder is a major cause of deterioration of the transmission characteristics of the wire (particularly when the wire is an optical fiber), and also causes a problem in drawing out the wire. For example, when a flat wire material such as an optical fiber ribbon is taken as an example, the winding may be broken by overlapping the mountain of the lower layer at the brim, or it may be wound without depending on the brim, It is unavoidable that a winding disorder occurs such that the tape core wire falls into the gap.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and in order to reliably prevent winding disorder of the wire rod, the reversal position of the bobbin in the traverse direction is tried for each winding. It is an object of the present invention to provide a changing winding machine.

[0004]

Means taken for solving the problems Means taken for solving the above problems of the present invention are constituted by the following elements (a) to (g). (A) A protrusion for detection is provided on the side of the winder body that reciprocates left and right guided by the guide rail, and (b) a pair of left and right sensors on the screw shaft parallel to the guide rail of the winder. The block is screwed together, and this sensor block is guided to the left and right by a screw shaft so that it can reciprocate left and right. (C) The optical sensor is mounted on each of the sensor blocks. (D) The screw shaft is driven by a pulse motor. (E) When the optical sensor detects the position of the protrusion to be detected, the detection signal is transmitted to the traverse drive control device, and thereby the bobbin traverse drive motor is reversed. Is driven by a pulse motor, and the pulse motor is controlled by a traverse reversal position control device. It includes a processor, each time the traverse reversing operation, pre accordance programmed law, predetermined pitch position of the wire winding of the sensor block, controls the pulse motor to move from the reference position to the left and right.

[0005]

[Operation] Control the pulse motor by an external signal,
The sensor block is moved left and right along a screw axis parallel to the bobbin axis to determine the reference position of the optical sensor mounted on the sensor block. This adjustment is automatically performed by inputting data regarding the position of the winding path of the wire rod, the width of the bobbin, the thickness of the wire rod, etc. into the microprocessor of the traverse reversal position control device. In this state,
When the winding of the wire is started and the winding machine moves to the left or right, either the left or right optical sensor detects the edge of the protrusion to be detected, and the detection signal is transmitted to the traverse control device of the bobbin traverse drive motor. As a result, the traverse control device reverses the bobbin traverse drive motor and reverses the traverse direction of the bobbin. The timing of this inversion start is when the wire is wound up to a predetermined position at the brim of the bobbin. Therefore, the traverse direction of the bobbin is reversed when the wire is accurately wound up to a predetermined position on the brim of the bobbin. The traverse direction of the bobbin is reversed, the opposite edge of the protrusion on the opposite side is detected by the optical sensor, and the traverse direction of the bobbin is reversed again. By repeating this operation, the wire rod is accurately wound up to a predetermined position.
On the other hand, when the edge of the protrusion for detection is detected by the optical sensor, the detection signal is transmitted to the microprocessor of the traverse reversal position control device, and the traverse reversal position control device drives the pulse motor for driving the screw shaft. , The position of the sensor block is moved right and left by a predetermined pitch of the wire rod. By repeating this operation, the wire rod is accurately shifted by a predetermined pitch with respect to the lower winding layer and wound. Therefore, regardless of the size of the bobbin width, the size of the wire rod, etc., it is possible to invert inside the bobbin brim once every two inversions at each brim. In (1), it is not overlapped with the winding layer pile, and it is possible to prevent the brim from opening, and winding disorder is not caused by these. The control of the pulse motor by the above traverse reversal position control device is performed as follows. That is, first, when the wire is wound until it reaches one brim of the bobbin, the detection signal of the optical sensor is transmitted to the microprocessor of the traverse reversal position control device, and the pulse motor is controlled by the control device according to a predetermined program. When driven, the left and right sensor blocks are moved leftward from the reference position by a predetermined pitch to prepare for the next leftward reversal of the traverse of the bobbin. When the wire rod reaches the other brim of the bobbin, the optical sensor of the sensor block that has moved leftward by a predetermined pitch detects the edge of the protrusion to be detected at that position. Therefore,
With the sensor position unchanged, the traverse of the bobbin is reversed to the right, so that the optical sensor detects the edge of the protrusion for detection at the position where the wire rod leaves a predetermined pitch from one brim, and the traverse of the bobbin is moved. The left and right sensor blocks are flipped to the left and the right and left sensor blocks are moved to the right by a predetermined pitch. Then, the wire rod is wound up from the other brim to a position where a predetermined pitch remains. In this way, the bobbin traverse is reversed to the left and right (for the above sequence, refer to the winding order shown in FIG. 2).
Since the reference position of the optical sensor is automatically and accurately adjusted and the traverse reversal timing is accurately detected by the optical sensor, the bobbin traverse direction inversion timing and the stroke of each traverse are accurately measured.

EXAMPLES Next, examples of the present invention will be described with reference to the drawings. The drawings show an example of a winding machine for a multi-core optical fiber ribbon. FIG. 1 is a plan view of an embodiment of the present invention. The winder body 1 is supported by a pair of guide rails 2 and 2 so as to be capable of reciprocating (traverse) in the direction of arrow XX, and is reciprocally driven by a traverse drive mechanism. Since this traverse drive mechanism is a conventionally well-known one, its detailed description is omitted. The drive motor of the traverse drive mechanism is controlled by the traverse drive control device. A sensor block drive screw shaft 4 parallel to the guide rail 2 is arranged on the side of the winder body 1,
A pair of left and right sensor blocks 5, 5 are screwed onto the screw shaft. The sensor blocks 5 and 5 are slidably guided in the traverse direction XX by a guide rail R parallel to the screw shaft 4. The screw shaft 4 is driven by a pulse motor 6. Reflection type optical sensors 7 and 7'are attached to the sensor blocks 5 and 5, and the direction of the light beam b thereof is a direction perpendicular to the screw axis 4. Reflection type optical sensors 7 and 7'detect the moment when the left and right edges of the tip of the projection 3 to be detected provided on the side surface of the winder main body 1 cross the optical sensors 7 and 7 '. At the position where the optical fiber ribbon 10 is wound up to the collars 9 and 9'of the bobbin 8 mounted on the winder body 1, the light beam b is detected by the projection 3 for detection.
The positions of the sensor blocks 5 and 5 are adjusted so as to match the above-mentioned edges of. This adjustment is automatically performed by the traverse reversal position controller PC which controls the pulse motor. When the reference position S is determined, the traverse driving device starts to operate and the optical fiber ribbon 10
The winding of is started. When any of the optical sensors 7 and 7'detects the reflected light from the above-mentioned edge of the projection to be detected, the detection signal is a traverse drive control device D of the winder.
After being transmitted to C, the traverse drive motor DM (details not shown) is reversed to reverse the traverse direction of the bobbin. When any of the optical sensors 7 and 7'detects the reflected light from the edge of the projection to be detected, the detection signal is transmitted to the traverse reversal position control device PC for controlling the pulse motor 6, and the detection signal is used. The pulse motor 6 performs a predetermined forward rotation and a reverse rotation according to a rule programmed in advance by the microprocessor of the traverse reverse position control device PC, and the left and right sensor blocks 5 and 5'are set to a predetermined pitch of winding the optical fiber ribbon. It is moved from the reference position S to the left and right to prepare for detection of the next traverse inversion position. Next, the sequence of the traverse inversion operation for the winding method of FIG. 2 will be described. The winding method of this embodiment is an example in which the cores of the tape are intermittently wound at intervals of the width. The winding sequence proceeds from 2-1 to 2-4 according to the arrow. Initially, the position of the optical sensor block is such that the left side is a position where the tape core wire is separated from the brim by 1/2 pitch, that is, the width of the tape core wire, and the right side is a position where the tape core wire is where the tape core comes to the brim. is there.
For winding, a half pitch, that is, the width of the tape core wire is left on the right side of the bobbin, and the tape width is opened, and the winding is intermittently started, and when the edge reaches the left edge, it is further wound around the edge ( 2-1). At the end of one round, the two sensors are reversed, and at the same time, both sensors are moved to the left by ½ pitch, that is, the width of the tape core wire while keeping the interval. The tape core wire is wound toward the right and intermittently at the point where it is open and reaches the brim at the right end, but when it reaches the brim, it is wrapped once again as above. (2-2). By this one reciprocation, the tape core wire is wound around the bobbin even more and without any clearance at the brim of the bobbin. Next, the position of the sensor was left as it was, only the tape was reversed, and the tape width was opened, and the tape was wound toward the left intermittently, and this time, the left end was left at a half pitch, that is, the width of the tape core wire. Occasionally, it makes one round along the plane perpendicular to the bobbin axis at that position (2-3). Next, while reversing, both sensors are moved to the right by ½ pitch, that is, the width of the tape core wire while keeping the interval, and intermittently wound to the right while opening the tape width. When a half pitch, that is, the width of the tape core wire, is left at the right end, one round is made along the plane perpendicular to the bobbin axis at that position (2-4). After that, repeat this. Thus, the tape core wire is wound one by one in one reciprocating motion, and is always wound every other time on the brim of the bobbin, and is not overwound.

[Effect] The object of the present invention is novel. Therefore, it is a peculiar effect of the present invention that this problem is solved and the problems inherent in the above-mentioned prior art are solved. Further, according to the present invention, since the position of the sensor can be automatically set and adjusted, it is possible to omit the manpower for performing the position setting and adjustment, so that the cost for winding the wire rod can be significantly reduced. it can. Also, since the winding is performed while changing the traverse width, regardless of the bobbin width error due to manufacturing error,
The wire can be wound up accurately up to the flange.
Therefore, it is completely unnecessary to consider the manufacturing error of the bobbin in the position adjustment of the sensor. Furthermore, since the left and right edges of one projection to be detected can be detected by the two sensors, the traverse position detecting mechanism and the sensor position adjusting mechanism can be extremely simplified. Furthermore, since the reliability of the winding disturbance prevention is extremely high, a monitoring staff for promptly detecting the occurrence of the winding disturbance is unnecessary, and the labor cost saving effect in this respect is also great.
