Abstract

PURPOSE:To enable uniform surface-treatment of yarn throughout the whole circumference of the yarn by transporting the yarn under rotation by the cooperative action of a sun gear and a planetary gear placed in an unwinding part and a winding part, respectively. CONSTITUTION:Yarn to be treated is unwound from a bobbin 85 attached to an unwinding part 8, an end of the yarn is fixed to an empty bobbin 95 attached to a winding part 9 and the shafts 80, 90 are rotated by actuating a driving part. In the unwinding part 8, a 1st bobbin holder 82 is rotated by the rotation of the shaft 80 and the bobbin 85 is revolved and rotated by the 1st planetary gear 83 and a gear 86 intermeshed with the 1st sun gear 81. Similarly, in the winding part 9, the empty bobbin 95 is revolved and rotated at the same speed as the bobbin 85 by the cooperative action of the 2nd sun gear 91, the 2nd bobbin holder 92 and the 2nd planetary gear 93 by the rotation of the shaft 90. When a plasma generator A, etc., is placed between the bobbins 85 and 95, the yarn is transferred from the unwinding part 8 to the winding part 9 under rotation by the revolution and rotation of both bobbins 85, 95 and is subjected to plasma treatment.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a winding and feeding device that rotates and runs a yarn in order to process the yarn.

Prior art and its problems Surface treatments such as low-temperature plasma processing such as etching, plasma polymerization, plasma CVD, sputter coating, and vacuum evaporation have directional properties depending on the flight direction of particles. For this reason, for example, when processing a film-like workpiece, a method has been used in which the front and back sides are processed one by one. However, when the workpiece is a filament, a rope, a thread, a cord, etc., and there is no distinction between front and back, and the entire circumference needs to be treated, the above method cannot uniformly treat the entire circumference of the yarn surface. In order to perform uniform surface treatment on the yarn, it is necessary to arrange a large number of surface treatment devices surrounding the yarn, making the entire device complex and large, and the surface treatment of the yarn is expensive. Become something.

SUMMARY OF THE INVENTION An object of the present invention is to provide a simple device that can uniformly apply surface treatment to yarn.

Means for Solving the Problems The object of the present invention is to provide a feeding section and a winding section, which are arranged on a base at an interval necessary for processing the yarn, and a driving section thereof, the feeding section comprising: a first sun gear fixed to the base with its teeth facing the winding section; and a first bobbin supported by the base having the same rotational axis as the axis of the first sun gear. a first planet gear rotatably supported by the first bobbin receiver with its axis perpendicular to the axis of the first sun gear and meshing with the first sun gear; a first bobbin that is rotated around an axis perpendicular to the axis of the first sun gear; a gear, a second bobbin receiver supported on the base with the same rotational axis as the axis of the second sun gear, and the second bobbin receiver with the axis perpendicular to the axis of the second sun gear. a second planetary gear rotatably supported by the second sun gear and meshing with the second sun gear; and a second bobbin supported by the second bobbin receiver and rotated about an axis perpendicular to the axis of the second sun gear. This is achieved by a yarn processing winding and feeding device characterized in that the drive unit drives the first planetary gear and the second planetary gear to rotate at the same speed.

Further, in the device, the first bobbin receiver includes a first central guide for guiding the yarn from the first bobbin onto the rotation axis of the first sun gear, and the second bobbin receiver includes a first center guide for guiding the yarn from the first bobbin onto the rotation axis of the first sun gear. an introduction device that moves in the axial direction of the bobbin as yarn winding progresses to the second bobbin and guides the yarn to the winding position; and an introduction device that guides the yarn to the winding position on the upstream side of the introduction device; and a second central guide to maintain the position on the line.

As shown in FIG. 2b, the winding part (9) is a frame (10) in which a second sun gear (91) is located at the other end of the base.

The frame (10) is rotatably supported through a shaft (90) passing through the center hole of the second sun gear (91), and a U-shaped second bobbin receiver (92) is provided at the end of the shaft (90). ) is fixed. The second bobbin receiver (92) rotatably supports the shaft of the second planetary gear (93) on the outside of the U-shape with its axis perpendicular to the second sun gear (91). Two bobbins (95) are rotatably supported inside the U-shape around an axis perpendicular to the axis of the sun gear (91). The second bobbin (95

(34), thereby rotating the shaft (80), (
90).

An etching plasma apparatus (A) is arranged between the feeding section (8) and the winding section (9). The plasma device (A) includes electrodes (al) and (a2), and the feeding section and winding section on the base and the plasma device (A) are equipped with a cover (
The base (2) is provided with a suction part (C) which is airtightly closed by the cover (B) and which creates a vacuum inside the cover (B).

Next, how to use this device will be explained.

Open the cover (B), attach the bobbin (85) wrapped with yarn to be processed to the feeding section (8), and remove the empty bobbin (95).
is attached to the winding section (9), the yarn of the bobbin (85) is pulled out, and the end portion is locked to the bobbin (95). Then cover (
B) is mounted on the base (2), and a vacuum device (not shown) is activated to reduce the pressure inside the cover. When the pressure is reduced to a predetermined level, the electrodes of the plasma device (A) are energized to generate plasma, and the transmission motor of the drive unit is operated. Due to the rotation of the motor, the shaft (8
0) and (90) rotate.

In the feeding section (8), the rotation of the shaft (80) causes the first
The bobbin receiver (82) rotates in the direction shown by the arrow (E) together with the first planetary gear (83) and the like (see FIG. 3).

At this time, since the gear (83) meshes with the first sun gear (81), it rotates on its own axis as it rotates in the direction of arrow (E).

The rotation of the gear (83) is caused by the rotation of the gear (84) via the gear (86).
), thereby causing the bobbin (85) to also rotate.

The direction of rotation of the drive is selected such that rotation of the bobbin (85) causes the yarn on the bobbin to be taken out.

In addition, in the winding section (9), due to the rotation of the shaft (90), the second bobbin receiver (92) is moved along with the second planetary gear (93), etc., as shown by the arrow (E) in the feeding section (8). Rotate in the same direction as the direction. At this time, since the gear (93) meshes with the second sun gear (91), it rotates on its own axis as it rotates in the direction of arrow (E). The rotation of gear (93) is gear (94)
This causes the bobbin (95) to also rotate. In this case, the winding part (9) has a gear (86) of the feeding part (8).
) Since there is no intermediate gear corresponding to bobbin (95)
The rotation direction of the bobbin (85) is the same as that of the bobbin (85). Further, since the gears (83) and (93) and (84) and (94) have the same number of teeth, the bobbins (85) and (95) rotate at the same speed.

Therefore, the yarn is fed out and wound up as the bobbins (85) and (95) rotate, and furthermore, the yarn is fed out and wound up as the bobbins (85) and (95) rotate.
95), the surfaces facing the electrodes (al) and (a2) continuously rotate and change.

In this example, the yarn is set to revolve once while passing through a region to be treated by the plasma device (A). Therefore, as the unwinding and winding progress,
The entire circumferential surface of the yarn is processed uniformly.
