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 controlling the winding of a filament, and more specifically, to eliminate the phenomenon of winding up and down on the inner surface of each collar plate of a winding bobbin. The present invention relates to a method and a device for controlling the winding of a filament body so that the winding bobbin can be aligned between the two collar plates.

[0002]

2. Description of the Related Art An example of a conventional device for winding a filament on a winding bobbin will be described with reference to FIG. The linear body 1 guided by the winding guide roller 102 rotatably supported by the guide roller support body 101.
Is wound on a winding bobbin 2 which is driven to rotate by a bobbin rotation drive motor 4. The entire rotating mechanism rides on a traverse frame 3 and is traversed in the direction of this axis by a traverse shaft 5 rotated by a traverse drive motor 6, so that the filament 1 has two collar plates 21, 21 of the winding bobbin 2. It will be lined up in between.

A guide shaft 103 is provided parallel to the traverse shaft 5, and two detecting means 104A and 104B are provided slidably along the guide shaft 103. These detecting means 104A and 104B are excited by the approach of a dog 7 provided at an appropriate position of the traverse frame 3, and issue a reversal command of the traverse reciprocating motion of the traverse frame 3.

As shown in FIG. 5, this detecting means 104A
The guide shaft 10 by loosening the fixing screw 105.
The position can be adjusted by freely sliding on 3. Therefore, as shown in FIG. 3 (a) which is an enlarged view of a portion in contact with the inner surface of the collar plate, one collar plate 21 of the take-up bobbin 2 (provisionally, FIG.
If the winding-up phenomenon (turning up of the turn) of the linear body 1 occurs inside (on the left side of), the traverse inversion command is slow, so the detection means 104B in charge of issuing this command is shifted to the left side. If the filament body 1 is rolled down (a gap larger than the diameter of the filament body is formed between the filament body 1) as shown in FIG. 3B, the traverse inversion command is too early. Therefore, the detection means 104B is shifted to the right and adjusted.

[0005]

As described above, according to the conventional method, the operator loosens the fixing screw 105 and moves the detecting means 104A and 104B one by one, and the fixed position after the adjustment is determined to some extent by the eye register. If there is, it is necessary to re-adjust the reels to align and wind them on the take-up bobbin, and the operator must manually adjust the adjustment width. However, there is a disadvantage that the linear winding of the filaments cannot be efficiently performed.

[0006]

The present invention has been made to solve the above-mentioned problems, and the solution means according to the invention of claim 1 is to traverse a filament body to a winding bobbin. While winding, the detecting means for emitting a traverse inversion signal is provided at two positions set along the traverse direction corresponding to the traverse width, and these detecting means are adjusted and moved in the traverse direction to move the linear body. In the winding control method of the linear body for performing the aligned winding on the winding bobbin, the winding-up or winding-down phenomenon of the linear body on the inner side surface of one collar plate of the winding bobbin is automatically performed. A line characterized by carrying out an aligned winding by automatically moving and adjusting the detecting means for detecting and detecting the traverse inversion signal for directing the winding bobbin to the other collar plate. The body is a take-up control method of.

According to a second aspect of the present invention, there is provided a means for solving the above problem, wherein two detecting means are provided which are spaced apart from each other along the traverse direction of the winding bobbin for winding the filament body and which generate a traverse inversion signal. A driving device that moves the detection means in the traverse direction and a winding guide roller that rotatably guides the linear body are rotatably supported, and a bending direction in which elastic deformation is parallel to a rotation surface of the winding guide roller is performed. A filamentous body winding control device having elastic members and detection means arranged on both sides in the direction of elastic deformation of the bending elastic member and activating the drive device.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described with reference to FIGS. Parts that are the same as the parts of the prior art already described with reference to FIG. 4 are denoted by the same reference numerals and description thereof is omitted, and differences from the prior art will be mainly described.

In the apparatus of the present invention, the winding guide roller 10 is rotatably supported by a bending elastic member 11 such as a thin plate or a wire spring which is easily bent and deformed. It is important that it is set parallel to the plane of rotation of the roller 10. Therefore, detection means 12A and 12B for detecting the winding-up and winding-down phenomena occurring on the inner surface of the collar plate 21 of the winding bobbin 2 are provided on both sides of the bending elastic member 11 in the bending deformation direction.

Detecting means 8 for issuing a traverse inversion command
A and 8B are attached to the supports 81 and 82, respectively,
These are the feed screw shafts 9 parallel to the traverse shaft 5, respectively.
It is made possible to adjust the movement to the left and right by 1, 92.
A necessary guide rod is provided as shown in the drawing so that the body is not tilted and twisted during the screw feeding of the supports 81 and 82.

The feed screw shafts 91, 92 are provided with adjusting feed motors 9A, 9B for rotating the feed screw shafts 91, 92, respectively. As the adjustment feed motors 9A and 9B, for example, a stepping motor that can rotate in forward and reverse directions and can rotate at a minute angle is suitable. Considering the above operation, in the claims, the feed screw shafts 91, 92 and the adjusting feed motors 9A, 9
B is collectively used as a driving device.

As shown in FIG. 1, the detecting means 12A and 12B excite the adjusting feed motor 9A to detect when the filament 1 is approaching the inner surface of the collar plate 21 on the left side of the winding bobbin 2. It controls the adjustment movement of the means 8A (detection means 12A
Adjustment feed motor 9A
Although the rotation direction is opposite), the adjusting feed motor 9B is excited to control the adjusting movement of the detecting means 8B when it is approaching the inner surface of the right collar plate 21 (not shown). Although not shown, it should be understood that a separate switch for this purpose is provided.

The operation of the above-described configuration of the present invention will be described. As an example, as shown in FIG. 1, the winding bobbin 2 is traversing in the right direction and the filament 1 is approaching the inner surface of the collar plate 21 on the left side of the winding bobbin 2. If the filamentous body 1 rolls up as shown in FIG. 3 (a), the winding radius rapidly increases, so that the amount of withdrawal increases and the tension of the filamentous body 1 temporarily increases. The bending elastic member 11 supporting the guide roller 10 bends to the right in FIG. 2, and the detection means 12A is excited. As a result, the adjustment feed motor 9A rotates to move the detection means 8A to the left in FIG. 1, and the traverse reversal command is issued earlier so as to quickly return the winding bobbin 2 to the left. Will be done.

On the contrary, it is assumed that the filament 1 is rolled down at the same location inside the collar plate as described above. In this case, it is not responsive in time, but while the formation of one winding layer progresses, one filament is not completely enough to the inner winding layer. Occurs, and at this time, the tension of the filamentous body 1 temporarily decreases.

At this time, in FIG. 2, the bending elastic member 11 supporting the winding guide roller 10 bends to the left, the detection means 12B is excited, and the adjusting feed motor 9A is rotated in the reverse direction to delay the traverse inversion command. The detecting means 8A is moved and adjusted to the right in FIG. In the case of this winding down adjustment, there is already traverse inversion, and the winding bobbin 2
It can be understood that this adjustment is effective from the next traverse reversal of the left collar plate 21 since the one traverse is moving to the left and one winding layer is being formed.

A contact type or non-contact type switch or sensor is used as the detecting means described above. A magnetic or optical proximity switch is preferably used as the non-contact type switch.

[0017]

According to the present invention, the behavior of the linear body on the inner surface of the collar plate of the take-up bobbin does not have to be adjusted by the worker to loosen or tighten the fixing screw. Accordingly, the adjusting means is automatically moved, and there is an advantage that the linear body can be easily aligned and wound onto the winding bobbin.
