Abstract

PURPOSE:To set the contact pressure in the traverse for cheese larger at the start of taking-up and smaller at the end by fixing the traverse position of a taking-up machine and allowing the taking-up machine to shift in the horizontal direction, providing a turning moment onto a cheese taking-up shaft and springily supporting the cheese taking-up shaft in the direction of the traverse shaft. CONSTITUTION:A cheese taking-up shaft 6 is revolved by the revolution of a belt drive 5, and said taking-up shaft 6 is installed rotatably onto a cheese taking-up bearing 9 installed in slidable ways onto a horizontal slidable guide 8. The cheese taking-up shaft 6 is springily supported in the direction of a traverse shaft 18 by a tension spring 19. Therefore, as the diameter of the cheese increases, the taking-up torque increases, and also the belt tension increases. Though the cheese taking-up shaft 6 tends to advance in the direction of revolution of the belt (reverse direction to that of the traverse shaft), the difference between the spring tension and the belt tension, namely the contact pressure reduces, since the spring tension is constant.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an improvement in a winding device for continuously winding a filamentous material.

<Prior art> Conventional winding devices have been used to wind yarns (monofilament, multifilament, flat yarn,
A method in which a traverse device is provided at the other end of an arm whose end is pivotally supported, and the traverse device rotates backward according to the winding amount of split yarn, braided yarn, etc. (hereinafter simply referred to as yarn). , ■ A method in which the traverse device is fixed and the take-up shaft is rotated and retracted has been put into practical use.

<Problems to be Solved by the Invention> According to the conventional methods as described above, the traverse device or the cheese (take-up shaft) moves in an arc in either case.

Fig. 4 shows the example shown in ■.
As the winding amount of 13) increases from the solid line to the double-dashed line, the amount of winding from the guide roller (16) to the traverse device (
7) and the introduction angle of the yarn (15) to the winding section (14) changed from a solid line to a two-dot chain line. At this time, the spring (17) elastically supporting the traverse device expands as it moves in an arc, and its tension becomes greater than when the cheese winding diameter is small.

However, the contact pressure of the traverse device against the cheese is configured to be smaller than when the cheese diameter is small due to the weight of the traverse device.

This is because the contact pressure is large at the beginning of winding, and by reducing the contact pressure at the end of winding, a neatly wound shape can be obtained.

Means for Solving the Problems> Unlike the above structure, the present invention fixes the traverse position of the winding machine and allows it to move almost horizontally while applying rotational force to the cheese winding shaft (6). The present invention provides a novel structure in which the cheese winding shaft (6) is resiliently supported in the direction of the traverse shaft (18).

<Function> As a result, the winding torque increases as the cheese diameter increases, so that the belt tension also increases as the radius increases. Therefore, the cheese winding shaft (6) is rotated in the belt rotation direction (
Try to move further in the direction opposite to the traverse axis). However, as shown in Figure 5, since the spring tension is constant, the difference between the spring tension and the belt tension, that is,
The contact pressure becomes smaller.

<Example> Embodiments of the present invention will be described in detail below with reference to the drawings.

The figure is a schematic diagram showing an example of conventional winding.

In the winding device of the present invention, the rotational force of the motor (1) is applied to the belt (2).
) to the winding shaft rotating belt drive (5) stretched between the pair of front and rear pulleys (3) (4), and this belt drive (5) (in this case, the timing belt)
The cheese winding shaft (6) is rotated by the rotation of the cheese winding shaft (6). The traverse device (7) is similar to the conventional device in that it traverses left and right with respect to the cheese (13), but the traverse position is constant. The cheese winding shaft (6) is slidably attached to two horizontal sliding guides (8) (8) provided horizontally on the main body of the device to enable horizontal movement. It is rotatably provided to a bearing (9). A pulley (10) is provided at the base of the cheese winding shaft (6), and guide rollers (
11) (12) are installed in a free rotation state. The belt drive (5) is stretched between these pulleys (10) and rollers (11) and (12). and,
A tension spring (19) is provided between the main body of the device provided with the traverse shaft (18) and the horizontally movable cheese winding bearing (9), and the cheese winding shaft (6) is moved in the direction of the traverse shaft (18). He provided support for the attack.

<Effects of the Invention> As shown in FIG. 3, according to the present invention, cheese (13
) As the winding amount increases from the solid line to the two-dot chain line, the winding torque increases, so the belt tension also increases. Therefore, the cheese winding shaft (6) tries to move further in the direction of rotation of the belt (in the direction opposite to the traverse shaft). However, as shown in FIG. 5, since the spring tension is constant (or tends to gradually decrease), the difference between the spring tension and the belt tension, that is, the contact pressure becomes small. In addition, since the traverse position and winding position are constant, the yarn (15
) is always constant. Therefore, the cheese rolled by the apparatus of the present invention has a very good shape, and the precision of the product can be improved.
