Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for adjusting the running of a filament.

[0002]

2. Description of the Related Art A device shown in FIG. 3 is a feeding device 2 in which a filament 1 such as a tape core wire is rotationally driven by a feeding drive motor 3 such as an AC servomotor.
From the swinging dancer roller device 4 (an end portion of an arm 41 rotatable about one center is provided with a roller 42).
Is rotatably attached, and is located at the end of the line through a device for adjusting minute tension fluctuations occurring in the linear body 1, that is, fluctuations in the feed amount of the linear body by swinging the arm 41). 3 shows a device line sent to the machine 5.

[0003]

When the feed drive motor 3 suddenly stops due to a situation such as a power failure (especially, in the case of an AC servomotor, it suddenly stops), it is until the collective machine 5 at the line end stops. Since the rotation due to the inertia for a small time continues, the delivery amount of the filamentous body 1 to the collecting machine 5 is not in time, and the filamentous body 1 is easily broken.

In this case, the above-mentioned inconvenience may be solved by increasing the amount by which the swing dancer roller device 4 absorbs the variation in the delivery of the filamentous body 1.
As you may think, the swing dancer roller device 4
If the adjustment amount is increased, it becomes impossible to reliably absorb and adjust the minute tension fluctuations of the filamentous body 1 that are constantly occurring during the delivery process, and the above-mentioned inconvenience cannot be solved by such measures. is there.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and the invention of claim 1 locates the filament at the line end from the rotationally driven delivery device. A step of sending out to the collecting machine, a step of adjusting the fine fluctuation of the tension of the linear body via an oscillating dancer roller device, and a margin length with a length adjustable downstream of the oscillating dancer roller device. And a step of feeding out the stored margin length when the delivery device is suddenly stopped.

According to a second aspect of the present invention, two rotatable fixed rollers which are spaced apart at an appropriate interval along the running direction of the linear member, and the fixed roller and the rotating surface are the same, and are in proximity to them. Alternatively, it is a travel adjusting device for a linear body, which has a movable roller that is movably arranged in a separating direction and an actuator that drives the movable roller along the direction.

[0007]

The linear body is stored in the travel adjusting device composed of two fixed rollers and the movable roller, and the stored dose can be adjusted by moving the movable roller with respect to the fixed roller. When the delivery drive motor is stopped, the stored amount is paid out to cover the amount of filaments to be sent to the aggregate machine during the time until the aggregate machine stops, which is delayed by inertia due to inertia. . Differences in the length of rotation time due to the inertia of the aggregate machine depending on the model can be dealt with by setting the stored dose in advance for that aggregate machine.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An apparatus according to an embodiment of the present invention will be described with reference to FIG. A filament 1 such as a tape core is delivered from a delivery device 2 which is rotationally driven by a delivery drive motor 3 such as an AC servomotor. After that, the linear body 1 travels toward a collective machine 5 located at the end of the line via a swing dancer roller 4 (described above) for absorbing and adjusting a minute tension fluctuation.

The reference numeral 6 designates a travel adjusting device which is a characteristic element of the present invention. This is composed of two fixed rollers 61, 61 that are rotatably arranged at appropriate intervals d along the traveling direction of the linear body 1 and a perpendicular bisector of a line segment connecting the centers of these two. It is composed of one movable roller 62 which can move along the same plane of rotation.

The actuator that actually moves the movable roller 62 in the direction toward or away from the fixed roller 61 along the above-described vertical bisector is the rack and pinion device 7 in the embodiment shown in FIG.

That is, the movable roller 62 is rotatably supported on the tip of a movable roller support shaft 63, and a rack 71 is fixed to the movable roller support shaft 63, and the vertical bisector described above is provided by an appropriate guide frame. A pinion 72 that is slidably guided along the rack 71 and meshes with the rack 71 is rotationally driven by a pinion drive motor 73. A pulse motor or the like is suitable as the pinion drive motor 73.

If the length of the path of the filament 1 from the fixed roller 61 on the upstream side to the fixed roller 61 on the downstream side via the movable roller 62 is L, this is stored by the travel adjusting device 6. It is the size of the dose. Then length (L
-D) shows the travel adjusting device 6 when the lower edge of the movable roller 62 rises to the position of the line connecting the centers of the fixed rollers 61.
It is the maximum adjustment amount that can be paid out from, in other words, the margin of the striatum.

The travel adjusting device 6 of the present invention is used as follows. First, the maximum adjustment amount is known according to the magnitude of inertia depending on the model of the collective machine 5 or the operating speed, and the position of the movable roller 62 is determined in advance so as to match the maximum adjustment amount. Specifically, the running adjustment device 6 is checked by checking the length of the filamentous body 1 sucked into the gathering machine 5 from the time when the delivery drive motor 3 is stopped until the rotation of the gathering machine 5 due to its inertia is stopped. That is, the maximum adjustment amount of is set so as not to be shorter than the length.

In actual use, a signal circuit 9 is provided as a control system to notify the pinion drive motor 73 when the stop of the delivery drive motor 3 is detected and to start the rotation. As a result, when the delivery drive motor 3 is stopped, this is immediately detected, the movable roller 62 rises, and the maximum adjustment amount of the filament 1, that is, the margin (Ld) is paid out and the filament 1 is disconnected. To avoid.

Another embodiment of the invention is shown in FIG.
This uses a fluid pressure drive device 8 as an actuator. That is, a fluid pressure cylinder 82 having a cylinder rod 81 that moves back and forth in the same direction as the movable direction of the movable roller support shaft 63 is provided, and an electromagnetic valve whose supply / discharge of fluid to / from this fluid pressure cylinder 82 is controlled to open / close by a signal circuit 9. 8
This is done by 3. Naturally, the fluid pressure cylinder 82 is selected so that the maximum stroke thereof does not fall below the planned movement amount of the movable roller 62.

[0016]

According to the first and second aspects of the present invention, the linear member is stored in the travel adjusting device composed of two fixed rollers and the movable roller, and the stored amount of the movable roller is fixed to the fixed roller. It can be adjusted by moving it to the other side, and when the delivery drive motor is stopped, it is delayed by the inertia by letting out this stored amount to the aggregate machine during the time until the aggregate machine stops, which is slower than when the delivery drive motor is stopped. Since it is possible to cover the amount of filaments to be sent, it has the effect of preventing disconnection accidents even when the delivery drive motor suddenly stops, and the difference in the length of rotation time due to the inertia of the collective machine depending on the model and operating speed. On the other hand, there is an advantage that it is easy to set the stored dose in advance according to the aggregate machine simply by determining the position of the movable roller.
