Description

Description: TECHNICAL FIELD The present invention relates to a yarn winding method for winding a yarn in a cone shape on a bottle beam having a tapered tapered portion on one side by using the tapered portion. Yes, and can be used, for example, when winding a creel onto a bottle beam for sizing. << Conventional Technology >> Many conventional beams of this kind use a so-called bottle beam, in which the winding portion is often cylindrical and one side has a tapered taper recently. Conventionally, the bottle-shaped cylinder has been used for partial warping, and the tapered part is used to wind the yarn around the cone, so the guide arm that also determines the winding position of the yarn around the cylinder is moved to the end of the taper It is necessary to wrap while winding. And it is necessary to perform this movement (horizontal direction) at a constant speed in consideration of the winding thickness of the yarn, and if it does not match the specific yarn thickness and winding speed, the cone shape along the tapered surface of the tapered part However, it will be a hindrance when unwinding. Therefore, in order to change the moving speed according to the thickness of the yarn, a method of changing a gear that controls the transmission speed of the moving mechanism has been adopted. Further, in order to perform the guiding operation accurately, it is preferable that the guide arm is as close as possible to the winding surface. Therefore, if the guide arm does not retreat with the lateral movement of the guide arm, the guide arm will hit the tapered portion. Therefore, the guide arm retreats and moves in the left-right direction, that is, the front-back movement mechanism and the left-right movement mechanism are mechanically linked to move so that the tapered surface of the tapered portion and the yarn layer surface are parallel to each other. The transmission gears and the adjustment gears for both moving speeds are selectively exchanged according to the thickness of the tape, and winding is performed. << Problems to be Solved by the Invention >> For the movement of the guide arm, a transmission gear is calculated and selected according to the thickness (denier) of the thread.
In practice, normal winding is not effected due to the material, tension and the like of the yarn, and the winding is performed by adjusting the taper angle by changing the taper angle. Therefore, after the guide arm is moved and the taper angle is changed and the test winding is performed for confirmation and adjustment, this work is performed, which takes a lot of trouble and requires a skilled operator. Therefore, the present invention is to provide a winding method that can easily perform a winding operation without requiring such gear change or taper angle adjustment. << Means for Solving the Problems >> A first yarn winding method for forming a cone using a tapered portion on a bottle beam having a tapered portion on one side according to the present invention is based on a first method. In the bobbin beam having a thick tapered part, in the yarn winding formed in the cone using the tapered part, it moves in the front and rear direction and the left and right direction,
A sensor is installed on the movement guide arm that determines the winding position of the winding yarn, facing the yarn winding surface, and the front and rear drive motor of the movement guide arm is used to maintain a constant distance from the winding surface detected by this sensor. In conjunction with this forward and backward movement, the transmission mechanism moves the left and right direction by the interlocking mechanism so that the ratio to the distance of forward and backward movement is the same as the aspect ratio of the angle of the slope of the tapered portion of the bottle beam. Thereby, the moving guide arm is moved so that the taper surface and the yarn layer surface become parallel. The second yarn winding method is a method of winding a bottle beam having a tapered portion tapered on one side into a cone by using the tapered portion, in which the yarn moves in the front-rear direction and the left-right direction, and is wound. The first sensor is installed on the moving guide arm that determines the winding position of the yarn, facing the yarn winding surface,
In order to keep the distance from the winding surface detected by the first sensor at a constant interval, the front / rear drive motor of the moving guide arm is controlled, and the second sensor is opposed to the parallel slope of the tapered portion by the moving guide arm. It is installed and controls the left and right drive motor of the moving guide arm to keep the distance from the parallel slope detected by this second sensor at a constant interval, and moves in the left and right direction according to the movement of the moving guide arm in the front and rear direction. Is performed to move the moving guide arm so that the tapered surface and the yarn layer surface are parallel to each other. << Operation >> The sensor installed on the moving guide arm that regulates the yarn wound around the bottle beam senses the distance from the winding surface facing the winding surface of the moving guide arm. When the thickness of the thread around the bottle beam is increased, the distance between the sensing portion of the sensor and the surface of the bottle beam (the thread is wound) becomes shorter. Therefore, a change in the sensing distance of the sensor activates the front-rear drive motor of the moving guide arm, and moves backward to maintain the set interval. In the first invention, the front-rear drive motor is used as a power source, and an interlocking mechanism for moving the moving guide arm in the left-right direction (in this case, the taper side direction) in conjunction with the front-rear moving mechanism of the moving guide arm acts to move. The guide arm moves to the left and right at the same time. And since the moving distance in the left-right direction is set in relation to the retreat distance so as to move so as to be the same as the aspect ratio of the taper angle of the taper portion, the moving guide arm moves in the left-right direction at the same time as the retreating. Then, the tapered portion moves so that the tapered surface and the yarn layer surface become parallel. Since the tapered surface is a specific inclined surface, once the moving distance in the left and right direction is set once, regardless of the thickness of the wound yarn, it will move in the left and right direction according to the thickness of the wound yarn, and the tapered surface Along the cone. Further, in the second invention, since the left and right drive motors for moving the moving guide arm in the left and right direction to keep a constant interval with the parallel slope are controlled by the second sensor installed opposite to the parallel slope of the tapered portion, When the moving guide arm retreats, the distance between the second sensor and the parallel slope changes, and at the same time, the second sensor senses and the left and right drive motors act to move in the left and right direction so as to keep the distance constant. The arm is moved so that the taper surface and the yarn layer surface are parallel. << Embodiment >> FIGS. 1 and 2 are a front view and a side view showing an embodiment of the first invention method, showing a relationship between a bottle beam and a moving guide arm. (1) is a bottle beam, one side of which has a thin and tapered (1a) cylindrical shape and rotates for winding the yarn.

Guide rod (5) fixed to the machine body (3) in parallel with (4)
Since the rollers (6) and (6) of the moving guide arm (2) are rolled and pinched, the moving guide arm (2) is parallel to the rotation axis direction of the bottle beam (1) by the rotation of the screw rod (4). Move left and right. Then, the screw (4) is rotated by the front-rear drive motor (8) via the speed change mechanism (7). The moving guide arm (2) determines the winding position of the bottle beam (1) around the thread via the supported tension roller (9), length measuring roller (10), and guide roller (11). The side frame (12) of the guide roller (11) has a support rod (13) extending above the bottle beam (1), and a sensor (14) at the tip faces the cylindrical center of the bottle beam (1). At the same time, it is installed at the position where the yarn is wound by the guide roller (11), and a rack rod (15) is provided at the base of the side frame (12) in parallel with the line connecting the sensor (14) and the center point of the cylinder, The rack rod (15) is supported by the support ring (1) of the moving guide arm (2).
6) Loosely insert into (16) to support side frame (12). Then, the rack rod (15) meshes with a rack gear (17) axially mounted on the movement guide arm (2), and the rack gear (17)
Is driven by a front-rear drive motor (8), and the front-rear drive motor (8) is a sensor (14) to keep a constant distance from the surface of the bottle beam (1) detected by the sensor (14).
And moves rearward (in a direction away from the bottle beam (1)) in accordance with the winding of the yarn. On the other hand, the movement in the left-right direction driven by the front-rear drive motor (8) by the rotation of the screw rod (4) is controlled by the speed change mechanism (7) in comparison with the retreat distance of the guide roller (11) of the side frame (12). The transmission mechanism (7) is set so that the aspect ratio of the angle (θ) of the slope of the tapered portion (1a) of the bottle beam (1) is the same. FIG. 3 shows an embodiment of the second invention method, in which a support rod (13) is used.
At the tip of the second sensor (1) together with the first sensor (14)

The arm (2) is retracted, but the front-rear drive motor (8) does not communicate with the screw (4). The second sensor (18) is provided to face the slope of the tapered portion (1a), and rotates a screw (4) provided separately from the front-rear drive motor (8) to keep the distance (b) to the slope constant. The right and left drive motor (not shown) to be controlled is controlled. The left and right drive motor moves with the front and back drive motor (8). Therefore, if the distance (a) from the winding surface set in the first sensor (14) changes, the front / rear drive motor (8) operates, the moving guide arm (2) retreats, and the second sensor (18) retreats. ) And the distance to the opposing slope change, the second sensor (8) senses the change in distance, and the left and right drive motor operates by the control of the second sensor (18) so as to keep the distance to the slope constant. The screw (4) is rotated to move the movable guide arm (2) in the left-right direction according to the retracted distance (c). (FIG. 3) << Effect of the Invention >> As described above, in the method of the present invention, the slope of the tapered portion is moved by moving the guide arm (guide roller) in the front-back and left-right directions corresponding to the thickness of the conventional wound yarn. In order to wind the cone along the line, each movement distance calculated in advance from the yarn thickness was previously selected by selecting the transmission gear, but the actual thickness of the wound yarn was detected by the sensor, and this was detected. The first invention directly or indirectly operates the front-rear drive motor to move based on the distance, and the second invention operates the left-right drive motor based on the sensing distance of the second sensor in the left-right direction. Therefore, the movement is not affected by the thickness of the yarn to be wound, and the movement can be performed accurately because the thickness is based on the actual winding thickness.
