Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a method for measuring the color of dyed yarn.

[Background technology]

Conventionally, the color measurement of dyed cheese threads dyed with a cheese dyeing machine has been carried out as follows. That is, first, as shown in FIG. 1, remove the screw 3 from the fixed shaft 2 of the carrier 1 of the cheese dyeing machine, take out one piece of dyed cheese 4, and place it on the rotary table 5 shown in FIG. The thread is attached, pulled out, passed through the thread path 6, rotated the frame 7, and wound around the outer circumference of the frame 7 to form a skein 8. Then, as shown in FIG. 3, this is placed in a hot air dryer 9a and dried.

Next, as shown in FIG. 4, the hot-air-dried skein 8 is mounted on the frame 7 again and re-rolled into a woodwind to form cheese.

Next, as shown in FIG. 5, the obtained cheese 4 is mounted on the rotary table 5, and put on a nine-knitting machine 9b for nine-knit socks to form a knitted fabric 8a.
This is then folded back by 2.3 degrees as shown in FIG. 6 to obtain a colorimetric sample 8b. Next, as shown in FIG. 7, this colorimetric sample 8b is attached to the colorimetric window B of the colorimeter A, and the colorimeter A is operated to perform colorimetry. However, when performing color measurement in this way, there are many steps from sampling to color measurement, so it takes a long time to get the color measurement results, and there is a problem that feedback to the site is delayed. . Furthermore, since the knitted fabric 8a is made by knitting yarn and used as the sample 8b for color measurement, a problem arises in that a large amount of yarn is required. Moreover, when knitting threads to make the sample 8b for color measurement, the threads cannot be arranged in high density, and stitches appear on the surface of the sample 8b made of the knitted fabric 8a, which adversely affects color measurement. Therefore, there is a problem that the accuracy of color measurement is poor.

[Purpose of the invention]

The present invention aims to provide a thread colorimetry method that can shorten the time required from thread sampling to completion of color measurement, does not require a large amount of thread for colorimetry, and can perform highly accurate colorimetry. That is the purpose.

[Disclosure of the invention]

In order to achieve the above object, the thread colorimetry method of the present invention involves rotating a cylinder around its axis to wind the thread around the outer circumferential surface of the cylinder. , which has a structure in which thread is tightly wound around the outer circumferential surface of a plate-shaped body with the winding direction aligned, and the plate-shaped body with this densely wound thread is attached to a colorimeter as it is to perform color measurement. It is.

In other words, this color measurement method does not involve removing the cheese from the dyeing machine, removing the cold, removing the cheese, and knitting it in the round, as in the past, but instead winding the thread around the outer circumferential surface of the cylindrical body and knitting it into a plate shape. Since the thread is rewrapped around the body and directly applied to the color measurement machine, the time required from sampling the thread to completing the color measurement can be significantly shortened.In addition, the thread can be measured as it is without knitting it as in the past. Because it is used for color measurement, it does not require a large amount of thread for color measurement.Furthermore, the color measurement machine is hung with a plate-like body made of densely wound thread, rather than knitted fabric with stitches as in the past. Colorimetry accuracy does not deteriorate due to stitches, and highly accurate colorimetry can be achieved.

Next, examples will be described.

That is, in this example, dyed yarns are sampled from cheese using a portable yarn sampling device as shown in FIGS. 8 and 9. In FIGS. 8 and 9, reference numeral 12 designates a pistol-shaped casing whose lower part is formed into a grip portion 13, which is divided into left and right halves, and is integrated with bolts and nuts. 14
16 is a shaft hole provided at the tip of the upper cylinder portion 15 of the pistol-shaped casing 12; 16 is a bearing fitted in the shaft hole 14;
Reference numeral 17 denotes a rotating shaft supported by the bearing 16. The tip side of this rotating shaft 17 protrudes forward from the tip of the upper cylinder part 15 of the pistol-shaped casing 12, and a rotating disk 18 with a center hole for fitting the sampling cylinder 10 is attached to the tip side of the rotating shaft 17. It is installed by fitting into its own center hole. The rotary disk 18 is constructed by forming a notched cylinder 20 on the surface of a disc-shaped substrate 19 as a fitting part for the sampling cylinder 10. in this case,
The cylinder with a notch 20 has a plurality of cylindrical support pieces 20a having an arch-shaped cross-section on the outer periphery of the surface of the disk-shaped substrate 19, and the arch is not aligned with the outer periphery of the disk-shaped substrate 19. They are formed by planting them at predetermined intervals. The sampling cylinder 10 is made of heat-resistant plastic and is removably fitted into the cylinder 20 with a notch formed of a plurality of cylinder support pieces 20a. 21 is a disk-shaped substrate 19
A boss portion 22 provided at the center of the surface is a fixing screw. The rear end side of the rotating shaft 17 is located within the upper cylindrical portion 15 of the casing 12, and a flywheel 24 having a ratchet pawl 23 is fixed thereto. 25 is a ratchet wheel, and 26 is a small bevel gear, both of which are integrally provided and are attached to the rear end of the rotating shaft 17 so as to be freely rotatable. Reference numeral 27 denotes a fixed shaft provided within the upper cylindrical portion 15 of the casing 12, and a compound gear 28 is rotatably provided on the fixed shaft. This composite gear 28 consists of a large bevel gear 29 and a pinion 30, and the large bevel gear 29 meshes with the small bevel gear 2-6. Reference numeral 31 denotes a drive lever formed on a rack 32 whose upper part meshes with the pinion 30, and which is connected to the grip part 13 of the pistol-shaped casing 12.
It is designed to swing left and right around a pivot 33 provided at the lower end of the holder. Reference numeral 34 denotes a guide hole drilled in the drive lever 31, which functions as a guide when the lever 31 swings. Reference numeral 35 denotes a guide protrusion provided on the grip portion 13 of the casing 12, which fits loosely with the guide hole 34 and guides the guide hole 3.
4 and exerts a guiding effect. This guide protrusion 35
It also acts as a stopper. 36 is the drive lever 3
1 is the return spring 37, and 37 is the upper cylinder part 1 of the casing 12.
It is a wire material extending downward from 5, and its lower end is formed into a thread path 38.

Sampling of dyed yarn using this portable sampling device 11 is performed as follows. That is,
As shown in FIG. 10, the sampling device 11 is brought close to the carrier 1 of the cheese dyeing machine, and the dyed thread is pulled out from the dyed cheese 4 mounted thereon and passed through the thread path 38 of the sampling device 11. Sampling cylinder 10
It locks on the outer circumferential surface of. From this state, hold the grip portion 13 of the sampling device 11 with one hand and press the drive lever 31 inward with your finger. As a result, the drive lever 31 is moved to the pivot 33.
The upper rack 32 rotates the pinion 30 of the composite gear 28 counterclockwise. This rotational drive of the pinion 30 causes the large bevel gear 29 of the compound gear 28 to rotate counterclockwise, and the small bevel gear 26 meshing with the large bevel gear 29 to rotate counterclockwise (positive direction). Ru. As the small bevel gear 2G rotates in the forward direction, the ratchet wheel 25 integrated therewith also rotates in the forward direction at the same time. The small bevel gear 26 and the ratchet wheel 25 are rotatably attached to the rotating shaft 17, and are originally designed to rotate separately from the rotating shaft 17.

However, when the ratchet wheel 25 rotates in the positive direction,
Due to the action of the ratchet pawl 23, the rotational force is transferred to the flywheel 1.
6 to the rotating shaft 17, and the rotating shaft 17 is rotationally driven in the forward direction. This forward rotation of the rotating shaft 17 causes the rotary disk 18 at the tip of the rotating shaft 17 to rotate in the forward direction, and the dyed thread is wound around the outer circumference of the sampling cylinder 10 that is detachably attached to the rotating gi 18. It will be done. After pressing the drive lever 31 inward to the fullest extent, the pressure on the drive lever 31 is released. As a result, the drive lever 31 returns to its initial state (the state shown in FIG. 9) by the spring force of the return spring 36. When the lever 31 returns, the pinion 30 is rotated clockwise (in the opposite direction), and thereby the large bevel gear 29, the small bevel gear 26, and the ratchet wheel 25 are rotationally driven in the opposite direction. Due to the action of the pawl 23, this rotational force in the opposite direction is not transmitted to the rotating shaft 17, and the rotating shaft 17 continues to rotate in the forward direction due to the inertial force of the flywheel 24. By repeating the pressing and releasing of the pressing on the drive lever 31 in this manner, the rotating shaft 17 continues to rotate in the forward direction, and the dyed thread continues to be wound around the outer peripheral surface of the sampling cylinder 10. Then, when a predetermined amount of the dyed thread has been wound, the sampling cylinder 1o is removed from the rotary disk 18, as shown in FIG. 11. In this case, the sampling cylinder 10 is elastically deformed and reduced in diameter by the tightening force of the dyed thread wound around the sampling cylinder 10, but the sampling cylinder 10 is attached to the notch of the rotary disk 18 into which the sampling cylinder 10 fits. The cylinder 2° is composed of a plurality of cylinder support pieces 20a, and since these support pieces 20a are elastically deformed inward according to the tightening force of the dyed thread, the sampling cylinder 10 is dyed. Due to the tightening force of the thread, it can be easily removed even if the diameter is reduced as described above. The sampling cylinder 10 removed in this way is
As shown in FIG. 2, it is placed in a household microwave oven 41 and dried. In this case, since the sampling cylinder 10 is much smaller than a cold, it is not dried in a hot air dryer, but is dried in the household microwave oven 41 as described above.

After drying, the sampling cylinder 10 is hung on a thread winding device 42, as shown in FIGS. 13 and 14, and the dyed yarn wound around its outer circumferential surface is re-wound onto the plate-shaped body 43. 13 and 14, 44 is a substrate;
5 is a cylindrical support for sampling provided on the substrate 44;
Reference numeral 46 designates the support column, and 47 designates a cylindrical body with a flange on one side, which is rotatably supported by the support column 46. The sampling river strip 10 is removably fitted into the cylindrical body 47 and supported by the support column 46. 48 and 49 are the first. It is a second frame, and on the outer surface of the first frame 48,
Large, medium, and small gears 50.5152 are rotatably arranged. The large gear 50 is provided with a handle 53, and when the handle 53 is rotated, the rotational force is transmitted to the small float 52 via the middle float 51. The body attachment part 54 is adapted to rotate. A slit 55 is formed in this plate-shaped body mounting portion 54, and the plate-shaped body 43 is detachably attached thereto by inserting the end portion into the slit 55 and securing it with a screw 56. Reference numerals 57 and 58 denote first and second helical rods, which are rotatably mounted parallel to each other between the first and second frames 48 and 49. Second spiral rod 58
is connected to the rotating shaft of the large gear 50, and the large gear 50
When the large gear 50 rotates, it rotates in the same direction as the large gear 50.

The first helical rod 57 is coupled to and rotates in the opposite direction to the second helical rod 58 by gears 59,60. 61 is the above-mentioned No. 1. Disposed between the second helical rods 57.58, the helical rods 57.5
A sliding piece that slides parallel to 8, and has the above-mentioned 1. A helical portion is formed which can engage the second helical rod 57,58. 62 is a leaf spring that always urges the sliding piece 61 in the direction of the second helical rod 58; 63 is a handle provided at the top of the sliding piece 61; and 64 is a guide when the sliding piece 61 is sliding. It is a guide rod that functions. 65 is a thread guide member having a thread path 66.

The process of rewinding the thread using this thread winding device is as follows.

It is carried out as follows. That is, in the cylindrical body 47 of the support base 45,
Sampling cylinder 1 with dyed thread wound around the outer circumferential surface
0, pull out the end of the dyed thread, and insert the thread guide member 6.
It passes through the thread path 66 of No. 5 and locks onto the outer circumferential surface of the plate-like body 43. Next, rotate the handle 63 with your left hand to turn the large gear clockwise. As a result, the second helical rod 58 rotates clockwise, the first helical rod 57 rotates counterclockwise, and the plate-shaped body 43 further rotates clockwise. As the plate-shaped body 43 rotates, the sampling cylinder 10 is pulled by the dyed thread and rotates, and the drawn out dyed thread is transferred to the thread path 6.
6 and is wound around the outer peripheral surface of the plate-shaped body 43 while maintaining a constant tension. Note that when rotating the handle 63 with the left hand as described above to rotate the large gear 50 clockwise,
At the same time, the handle 63 of the sliding piece 61 is pressed in the direction of the first helical rod 57 with the right hand. As a result, the sliding piece 61 tilts in the direction of the first helical rod 57 against the leaf spring 62, and the helical portion of the sliding piece 61 meshes with the helix of the first helical rod 57. The first helical rod 57 is rotationally driven by the rotational operation of the handle 63, and this rotational driving force causes the sliding piece 61 meshed with the first helical rod 57 to move forward (
As the sliding piece 61 is transferred, the thread guide member 65 is also sent forward. As a result, the thread guide member 65 is passed from the sampling cylinder 10 to the plate-like member 4.
The thread heading towards 3 is also sent forward. Therefore, the plate-like body 43
A thread is wound around the outer periphery of the plate-shaped body 43 from one end to the other end at regular intervals. When the sliding piece 61 is sent forward to the fullest limit, the sliding piece 61 abuts against the tapered part (stopper) of the truncated conical end of the first helical rod 57.

At this time, the pressure on the handle 63 is released. As a result, the sliding piece 61 is urged toward the second helical rod 58 by the spring force of the leaf spring 62, and its helical portion comes to mesh with the helix of the second helical rod 58. Since the second helical rod 58 is rotating in the opposite direction to the first helical rod 57, the sliding piece 61 is now moved backward. By repeating the advance and retreat of the sliding piece 61 in this way, the plate-shaped body 4
The threads are wound around the outer periphery of 3 at a high density with constant tension and in an aligned state. This state is shown in FIG.

Next, the plate-shaped body 43 with the thread wound around its outer peripheral surface is placed in the seventh position.
Measure the color using the colorimeter shown in the figure. In this way,
Color measurement of cheese dyed yarn is extremely easy.

〔Effect of the invention〕

As described above, the color measurement method of the present invention involves winding the thread around the outer circumferential surface of the cylinder, rewinding it around the plate, and applying it directly to the color measurement machine. This eliminates the need for a series of operations such as cheese removal, skein removal, cheese removal, and circular knitting, making it possible to significantly shorten the time required from yarn sampling to completion of color measurement. In addition, since the yarn is used for color measurement without being knitted as in the past, a large amount of yarn is not required for color measurement. In addition, because the colorimeter uses a plate-like body made of densely wound yarn, rather than a knitted fabric with stitches as in the past, there is no decrease in color measurement accuracy due to stitches, which improves accuracy. It becomes possible to perform high color measurement.
