Description

  The present invention relates to winding of a linear body such as an optical fiber and an electric wire, and particularly relates to a winding method and a winding apparatus for a linear body that process a cut portion when switching winding of the linear body.

  Conventionally, in the manufacture of filaments such as optical fibers and electric wires, when winding these filaments that are continuously fed at high speed with a winding bobbin, a predetermined amount of winding has been completed and fully wound. Switching from a winding bobbin (referred to as a first bobbin) to an empty winding bobbin (referred to as a second bobbin) that starts a new winding is performed without interrupting the running of the filament. .

  As such a winding device, the end portion of the linear body wound up by the first bobbin is taken up by the take-up means arranged between the first bobbin and the second bobbin, and then the full winding is performed. By locking the striate body with the first bobbin made in the vicinity or the locking claw provided in the vicinity thereof and cutting it, the winding end of the striate body of the first bobbin sways to the first bobbin. The trouble which damaged the wound linear body was prevented, and the linear body taken up by the taking-off means was sucked with the suction nozzle, and the taken-up linear body was wound up by the 1st bobbin. There is known a technique for preventing such a problem that the contact with the striatum is damaged (for example, see Patent Document 1).

JP 2005-211985 A1

  By the way, it is required to increase the winding speed for further speeding up the processing. However, when the winding speed is increased, it is necessary to increase the take-up speed of the filament by the take-up means.

  Then, at the time of switching the bobbin, the suction of the striate with the suction nozzle does not catch up with the take-up speed of the striate by the take-off means, and the striate protrudes from the suction nozzle and floats, Or, the suction of the striatum does not catch up at all, and the striatum floats. Then, the floating striated body may hit the surface of the striated body wound around the bobbin in the middle of deceleration after the winding is completed, and there is a possibility that the striking may occur. When a line hit occurs, the hit part must be discarded, and the length of scraps of the striatum increases, resulting in a decrease in yield.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a wire rod winding method and a winding device that can reliably prevent the occurrence of wire hitting when switching the bobbin that winds the wire rod while increasing the winding speed, and can ensure a high yield. To provide a take-off device.

The winding method of the linear body of the present invention that can solve the above-mentioned problem is the second one without stopping the travel of the linear body after stopping the winding of the linear body with the first bobbin. A method of winding a striatum with a bobbin,
When the winding is switched from the first bobbin to the second bobbin, the filament that is wound around the first bobbin by the take-up means disposed between the first bobbin and the second bobbin. Take the winding end of the body,
While sucking the filaments taken up by the take-up means by suction means,
A shielding plate is disposed on the extension in the emission direction of the linear member from the take-up means.

In addition, the winding device for a linear body according to the present invention, after finishing the winding of the linear body with the first bobbin, continues the linear body with the second bobbin without interrupting the travel of the linear body. A winding device,
A take-off means disposed between the first bobbin and the second bobbin, and taking up a winding end portion of the filament;
Suction means for sucking and accommodating the filaments taken up by the take-up means;
And a shielding plate disposed on the extension of the linear body in the emission direction from the take-up means.

According to the present invention, after the winding onto the first bobbin is completed, the linear body taken up by the taking-up means is sucked by the suction means and the shielding plate is extended on the extension of the linear body from the taking-up means in the emission direction. Therefore, the take-up speed of the striatum by the take-up means is fast, the suction of the striatum by the suction means cannot catch up, and the striatum jumps out of the suction means and floats, or the striatum Even if the striate does not catch up at all and the striate floats, the striatum taken up by the take-up means hits the shielding plate and is then guided to the suction means.
Therefore, the linear body taken up by the taking-up means is prevented from coming into contact with the linear body wound around the first bobbin rotating by inertia. As a result, it is possible to reliably prevent the occurrence of wire hitting with respect to the filament wound around the first bobbin while increasing the winding speed, and to ensure a high yield.

It is a figure which shows the example of embodiment which concerns on this invention, Comprising: It is a figure which shows the state in the middle of winding with a 1st bobbin. It is a figure which shows the state which moved the guide roller to the 2nd bobbin side in order to switch winding from the 1st bobbin side to the 2nd bobbin side. It is a figure which shows the taking-up state of a filament. It is a figure which shows the state which cut | disconnects the linear body by the side of a 1st bobbin, and prepares winding on the 2nd bobbin side. It is a figure which shows a mode that the taken-up linear body collides with a shielding board. It is a figure which shows the state from which winding by a 2nd bobbin is started.

Hereinafter, an example of an embodiment of a winding method and a winding device for a filament according to the present invention will be described with reference to the drawings.
In the description of the present invention, it is assumed that the bobbin arranged in the winding unit shown on the left side of the drawing is the first bobbin 2a and the bobbin arranged in the winding unit shown on the right side is the second bobbin 2b. As will be described, the first and second designations are given to clarify the configuration, and the right and left winding units may be used interchangeably. Further, the configuration related to the unit on the first bobbin 2a side is described with the symbol (a), and the configuration related to the unit on the second bobbin 2b side is labeled with the symbol (b).

  The winding method and winding device of the linear body of the present embodiment are configured by alternately switching the first bobbin 2a and the second bobbin 2b of the linear body 1, such as an optical fiber, a thin-diameter electric wire, or a cable. Thus, the filament 1 can be continuously wound at a high speed without being cut in the middle. The winding device of the present embodiment includes a take-up means, a locking means, a cutting means, a suction means, and a shielding means.

  As the take-up means, for example, as shown in FIG. 1, a structure comprising a driving roller 7 and pressing members 6 a and 6 b is used between the first bobbin 2 a and the second bobbin 2 b. Can do. This take-up means takes up the linear body 1 by the frictional force on the roller surface, displaces the pressing member 6a or 6b toward the driving roller 7, and presses the linear body 1 against the surface of the driving roller 7, The filament 1 is pulled in either direction by the frictional force of the roller surface. The take-up means is not particularly limited to the one shown in the drawing as long as it has a configuration capable of taking up the filament 1 at a predetermined linear speed by rotation control of the drive roller.

  As the locking means, any structure may be used as long as the winding start end or winding end of the linear body 1 is locked to the first and second bobbins 2a, 2b and the start and end of winding can be executed. . For example, this latching means can use the structure which attaches the claw wheels 5a and 5b to the at least one side of the 1st and 2nd bobbins 2a and 2b so that removal is possible, and rotates with a bobbin. The claw wheels 5a and 5b are provided with locking claws 10a and 10b capable of gripping and locking the linear body 1, and the linear body 1 is hooked and stopped by rotation of the bobbin.

  As a means for cutting the filament 1, various shapes of cutters 9 a and 9 b can be used although they are simply shown in the drawing. This cutting means performs a cutting operation in conjunction with locking the winding start end or winding end of the filament 1 to the locking means. Moreover, it is desirable to arrange | position so that the vicinity of the winding start end or winding end of the filament 1 may be cut | disconnected so that the length of the cut | disconnected terminal wire may become as short as possible.

  The suction means is composed of suction nozzles 8a and 8b that house the filament 1 taken by the take-up means. By the suction means, for example, the drawn wire 1 is not scattered or entangled around the equipment, and the labor for disposal can be reduced.

  The shielding means are shielding plates 11a and 11b made of flat plates, which are arranged between the take-up means consisting of the drive roller 7 and the pressing members 6a and 6b, respectively, and the first bobbin 2a and the second bobbin 2b. Yes. These shielding plates 11a and 11b are provided at a shielding position corresponding to an extension in the emission direction from the take-up means of the linear body 1 taken up by the driving roller 7 and the pressing members 6a and 6b, and above and outside the shielding position. It is moved between the retracted position that is off. The shielding position refers to the second bobbin from the vicinity of the pressing member 6a to the first bobbin 2a and from the vicinity of the pressing member 6b in order to block the linear body taken by the take-up means from hitting the bobbin. It exists between 2b. Furthermore, the shielding plates 11a and 11b shield between the suction nozzle 8a and the first bobbin 2a and between the suction nozzle 8b and the second bobbin 2b in order to block the filaments that could not be sucked by the suction nozzle. Is preferred.

  Next, an example of switching the winding from the first bobbin 2a that has finished winding to the empty second bobbin 2b will be described with respect to the winding method of the linear body of the present embodiment. FIG. 1 is a view showing a state in which the first bobbin 2a is being wound. The first bobbin 2a rotates clockwise, and the guide roller 3 for guiding the linear member 1 is a first bobbin. 2b and the second bobbin 2b. The linear body 1 is wound while relatively traversing the first bobbin 2a and the guide roller 3, but in the figure, the first bobbin 2a side is axially moved without traversing the guide roller 3 side. An example of traversing is shown. This example is said to be suitable for winding at a high speed with little deflection of the filament. Note that the guide roller 3 side may be traversed without moving the first bobbin 2a side.

  FIG. 2 shows that the winding body on the first bobbin 2a is fully wound or the winding is finished, and the guide roller 3 is moved to the empty second bobbin in order to switch the winding to the second bobbin 2b side. The state moved to the 2b side is shown. By moving the guide roller 3 toward the second bobbin 2b, the pass line of the filament 1 passes through the vicinity of the surface of the drive roller 7 and changes to a position close to or in contact with the body of the second bobbin 2b. At this stage, the driving roller 7 is rotated counterclockwise, and the second bobbin 2b is rotated counterclockwise. However, the pressing members 6a and 6b are still located away from the drive roller 7, and the wire body 1 is not started to be taken up. Therefore, the winding by the 1st bobbin 2a still continues only by the change of the pass line of the filament 1.

  FIG. 3 shows a state in which the left pressing member 6 a is displaced toward the driving roller 7 and the linear member 1 is pressed against the surface of the driving roller 7. At this stage, the take-up means operates and takes up the filament 1 in the left direction by the frictional force of the roller surface. When the 1st bobbin 2a is rotating, the taken-up filament 1 is wound up with the 1st bobbin 2a as it is.

  At this time, the left shielding plate 11a is moved from the retracted position to the shielding position, and is disposed on the extension in the direction in which the linear member 1 is taken out by the drive roller 7 and the pressing members 6a and 6b. Let

  FIG. 4 shows a state in which the filament 1 is cut on the first bobbin 2a side. While the linear body 1 is taken up by the driving roller 7 and the pressing member 6a and the winding with the first bobbin 2a is continued, the driving roller 7 and the pressing member 6a are taken up by the linear body 1. While moving in the direction of arrow E. By the movement of the drive roller 7 and the pressing member 6a, the pass line between the guide roller 3 is changed, and the filament 1 can be brought into contact with the claw wheel 5a of the first bobbin 2a. When the claw wheel 5a is brought into contact with the striate body 1, the striate body 1 can be gripped by the locking claw 10a on the claw wheel 5a. In addition, although the winding start end of the filament 1 is already locked to the locking claw 10a on the claw wheel 5a, it is desirable that the winding end is also formed so as to be locked. It is good also as a structure which provides a latching claw separately for winding start ends and winding end ends.

  In this state, when the linear body 1 is gripped by the locking claw 10a on the claw wheel 5a, the linear body 1 is moved and pulled together with the locking claw 10a by the rotation of the first bobbin 2a and hits the cutter 9a. Disconnected. The cut end wire 1a of the striate body 1 has a very short length from the portion gripped by the locking claw 10a, and does not swing around the first bobbin 2a. I don't hit the line. Therefore, even if the linear body 1 is cut in a rotating state, the wire hitting by this is not generated. And after cut | disconnecting the linear body 1, what is necessary is just to turn off a power supply in order to stop rotation of the 1st bobbin 2a. However, since the rotation of the first bobbin 2a is somewhat continued from the power-off to the complete stop due to inertia, the power may be turned off in a state just before the filament 1 is cut.

  Here, even after the filament 1 is cut on the first bobbin 2a side, the filament 1 is continuously taken up by the drive roller 7 and the pressing member 6a. The pulled wire 1 is sucked by suction means using a suction nozzle 8a. Thereby, driving | running | working of the filament 1 can be maintained and maintained with a predetermined linear velocity, without being interrupted. The sucked filament 1 is preferably stored in a suction box or the like installed below the suction nozzles 8a and 8b so as not to scatter around.

  At this time, when the take-up speed of the linear body 1 by the drive roller 7 and the pressing members 6a and 6b is high and the suction of the linear body 1 by the suction nozzle 8a cannot catch up, the driving roller 7 and the pressing members 6a and 6b. The striate body 1 taken out by the above may jump out of the suction nozzle 8a and float, or the striate body may float without catching up the suction of the striatum at all.

  However, at this time, as shown in FIG. 5, the shielding plate 11a is arranged at the shielding position on the extension in the direction in which the linear body 1 taken up by the driving roller 7 and the pressing members 6a and 6b is emitted. Therefore, the linear body 1 taken up by the drive roller 7 and the pressing members 6a and 6b collides with the shielding plate 11a, and is then guided to the suction nozzle 8a.

  Accordingly, it is possible to prevent the linear body 1 taken up by the drive roller 7 and the pressing members 6a and 6b from contacting the linear body 1 wound around the first bobbin 2a rotating by inertia. . As a result, it is possible to reliably prevent the occurrence of wire hitting with respect to the linear body 1 wound around the first bobbin 2a while increasing the winding speed, and to ensure a high yield.

  In the conventional method that does not use a shielding plate, line hitting occurs at a rate of about 67% when the bobbin is switched by increasing the winding speed. In this embodiment, however, the shielding plates 11a and 11b are provided. The occurrence of wire hitting was 0%.

  From the state of FIG. 4 or the state of FIG. 5, the drive roller 7 and the pressing member 6 a are further moved in the direction of arrow E while the linear member 1 is being taken up. In this state, when the linear body 1 is gripped by the locking claw 10b on the claw wheel 5b by the rotation of the second bobbin 2b, the linear body 1 moves together with the locking claw 10b by the rotation of the second bobbin 2b. And is cut by the cutter 9b. Thereby, the starting end of the linear body 1 becomes a free state, and new winding by the 2nd bobbin 2b is started.

  FIG. 6 shows a state in which the winding by the second bobbin 2b is started after the filament 1 is cut by the cutter 9b. On the other hand, the filament 1 cut by the cutter 9b and taken by the take-up means is sucked and stored in the suction means and discarded as an unnecessary item.

  In addition, the shielding plate 11a of the shielding means extends in the direction in which the linear body 1 taken up by the drive roller 7 and the pressing members 6a and 6b is emitted together with the start of a new winding by the second bobbin 2b. It moves to the retreat position which deviated upward and outward from the shielding position.

  The example of switching the winding from the first bobbin 2a of the left unit to the second bobbin 2b of the right unit has been described above, but the winding is performed from the second bobbin 2b of the right unit to the first bobbin 2a of the left unit. When switching between, the reverse movement can be performed. In this case, the drive roller 7 is rotated in the clockwise direction and is taken up with the linear member 1 being sandwiched between it and the pressing member 6b. Also, the suction means 8 operates the right suction nozzle 8b, and the shielding means operates the right shielding plate 11b.

  The present invention is particularly effective when the filament is an optical fiber drawn from an optical fiber preform. When the wound optical fiber is struck, the strength of the optical fiber is extremely reduced. Therefore, the struck part must be discarded. According to the present invention, even if the linear velocity is increased, it is possible to surely prevent the wire hitting when switching the winding, so that the winding can be switched without interrupting the traveling of the optical fiber without reducing the linear velocity. It is possible to improve the manufacturing efficiency and yield of the optical fiber.
