Description

[Detailed Description of the Invention] The present invention relates to a reeling four-filament guiding device for a slit-type fineness sensor.

In a slit-type fineness sensor, it is extremely important to run the reeled yarn parallel to the slit surface and at a determined slit depth position in order to improve the fineness sensing performance.

However, in the conventional device, fixed metal wires are installed before and after the slit-type fineness sensor, and four threads of reeling yarn are guided by the metal wires to be introduced into the slit-type fineness sensor, or they are installed before and after the slit-type fineness sensor. A drum wheel whose position can be adjusted freely is installed,
Four threads of reeled yarn are introduced into a slit-type fineness sensor and guided out through the drum wheel.

For this reason, in the former case, once the setting is made, it cannot be adjusted even if the contact between the slit part of the slit-type fineness sensor and the four reeling threads lacks running, and in the latter case, This method is disadvantageous in that the four reeling threads tend to run out due to eccentricity of the drum wheel and other causes, and it is difficult to set and maintain the correct contact position with the slit-type fineness sensor.

The purpose of the present invention is to obtain a device free of such inconveniences, and the slit portion 1a of the slit type fineness sensor 1 is provided on the reeling yarn introduction and lead-out side of the slit type fineness sensor 1.
In a device in which inductors 2, 2 for guiding four threads a of reeling yarn are provided, one of the inductors 2 is bent in a V-shape, and the guiding portion 2a of four threads a of reeling yarn is provided at the bent portion. It consists of a linear member 3 provided, one end of the linear member 3 is bent in a direction perpendicular to the four reeling threads a passing through the guiding part 2a, a screw part 2b is provided at the bent end, and the thread part 2b is provided at the bent end. A nut 7 is formed by fitting a boss 4 onto the threaded portion 2b and inserting the boss 4 into a long hole 6 along the slit direction of the slit type fineness sensor 1 provided in the machine frame 5. The linear member 3 is secured to the width of the slit portion 1a using a nut 8.8 which is provided in a desired position of the elongated hole 6 and is screwed into the threaded portion 2b provided at the end of the linear member 3. It is tightened so that it can be adjusted in any direction.

In the illustrated example, an inductor 2 provided on the outlet side of a fineness sensor 1 for four reeling yarns a is formed with a metal or other hard linear member 3 bent in a V-shape, and the yarn is guided at the bent part. One side bent in a V-shape is longer than the other side, and after the end is folded back, the yarn guiding portion 2a is formed.
was bent so as to be perpendicular to the four reeling yarns a to be operated, and the screw 2b was applied to the bent portion.

The boss 4 that fits into the threaded portion 2b is formed into a bolt shape, and after being inserted into the long hole 6 provided in the machine frame 5, the boss 4 is tightened with a nut 7 screwed onto the boss 4. It is tightened and fixed at a desired position in the hole 6.

In the drawing, 9 indicates a fineness indicating pin provided on the slit fiber sensor 1, 10 indicates a search claw for searching the fineness indicating pin 9, and the inductor 2 on the introduction side is provided at the swing center of the search claw 10. I applied the drum wheel to this.

Reference numeral 11 indicates a drum wheel provided at the tip of an arm 12 that protrudes from the lower end of the search claw 10. When the claw portion 10a of the search claw 10 retreats from the fineness indicating pin 9, the drum wheel 11 reels 4 threads a. The yarn was removed from the slit portion 1a as shown by the chain line to prevent the four reeling yarns a from constantly hitting certain portions of the slit portion 1a and being partially worn out.

13 is a winding frame for winding 4 threads a, 14 is a traversing mechanism, 15
1 is a swinging arm that swings when detecting abnormal tension in the four reeling threads a;
Reference numeral 6 denotes a stator that supports and fixes the middle of the linear member 3 that constitutes the inductor 2 provided on the lead-out side.

Each adjustment by this device is performed by fixing the retrieving claw 10 at the position shown by the solid line in FIG. If the thread a is moved along the elongated hole 6 and the depth position of the thread a relative to the slit portion 1a is determined, it is tightened and fixed with the nut 7.
The depth position is set.

Next, the nuts 8, 8 may be released from the tightened position, the wire 3 may be moved in the width direction of the slit 1a, and then the nuts 8, 8 may be tightened again.

In the above description, the inductor 2 on the outgoing side is adjustable, but the inductor 2 on the inlet side can also be adjusted.

In this way, according to the present invention, one of the inductors for introducing and guiding four reeling yarns into the slit portion of the slit type fineness sensor is provided so as to be freely adjustable in the depth direction and width direction of the slit portion. By adjusting the inductor, the depth position of the yarn a relative to the slit can be easily matched to a desired position, and the four reeling yarns can be precisely and easily positioned at the center position in the width direction of the slit. In addition to improving the sensing performance of the fineness sensor, since the inductor is made of a linear member that bends in a V-shape, it is easy to insert the four reeling threads into the guiding part. The inductor can be constructed by simply bending the inductor and providing a screw portion at its end, which has the advantage of being easy to manufacture and assemble.
