Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a warping method in a partial warping machine, and more specifically, a partial warping machine suitable for arranging a large number of colored yarns at a predetermined position and a predetermined length in consideration of a pattern after weaving. It relates to the warping method.
[0002]
[Prior art]
Conventionally, as a warping method, generally, a normal warping method and a partial warping method are appropriately employed according to process conditions. In the normal warping method, several hundred to about 1,000 warps are directly wound on a rough winding warp beam, and then a plurality of the obtained rough winding warp beams are combined and wound on a weaving beam having several thousand warps. Thereafter, weaving is performed by supplying the weaving beam thus obtained to the loom.
[0003]
The above-mentioned normal warping method is suitable for mass production in which a large number of warps are warped, but is not suitable for small lot multi-product production. Recently, a partial warping machine capable of warping from a yarn supply package having a quantity that is a few tenths of the total number of warps has been used for the production of a small variety of products and the manufacture of sample fabrics. (For example, see Patent Document 1)
[0004]
In the partial warping method, the yarn is first pulled out from a plurality of yarn supply packages (several dozens to several hundreds) mounted on the warping creel, and the taper side of the warping drum having a tapered winding surface is provided. A first band is formed at the end. That is, one yarn layer having a width smaller than the width in the axial direction of the drum is wound up while being inclined with respect to the shaft of the warping drum.
[0005]
Next, a second band is formed in the same manner so as to be adjacent to the first band. Further, this operation is repeated until a necessary total number of yarns are wound on the warping drum, thereby forming a partial warping beam having a plurality of bands. A single weaving beam is formed by simultaneously drawing yarn from a partially warped beam wound with the total number of yarns necessary for weaving. Furthermore, a single weaving beam can be formed from a plurality of partially warped beams.

[0020]
A method for manufacturing a yarn feeding package supplied to the partial warper according to the present invention will be described with reference to FIG. The yarns Y1, Y2, Y3 are pulled out from the packages P1, P2, P3... Mounted on the creel 10 and inserted through the tension applying member 11, and the yarn selection device 20, the yarn joining device 12, and the yarn length measuring storage device. 30 shows that the yarn supply package PW is manufactured by the winding drum 14 through the second tension applying member 13. Reference numeral 15 denotes a cradle that supports the yarn supply package PW.
[0021]
The packages P1, P2, P3,... Are packages having different colors and yarn types, and are continuously supplied to the yarn length measurement storage device 30 while being spliced by the yarn splicing device 12. Further, packages of color types and thread types necessary for producing a desired woven fabric are mounted on the creel 10, and are not limited to the three illustrated, but may be mounted on six or twelve. There is no limit to the quantity.
[0022]
The yarn selecting device 20 has yarn guides 21a, 21b, and 21c (see FIG. 3) arranged for the packages P1, P2, and P3, respectively, and guides the yarn Y to the yarn joining device 12 as will be described later. It is configured to be movably controlled to a yarn guide position (corresponding to 21A in the figure) and a position for guiding the yarn Y to the suction member 16 (corresponding to 21B in the figure).
[0023]
The yarn joining device 12 cuts and joins the yarn Y, and the yarn selected by the yarn selecting device 20 is guided by the guide guide 26 shown in FIG. It is configured. The yarn splicing device 12 may be a splicer device that splics air by an air vortex or may be a knotter device that performs yarn knotting. Whether to adopt a splicer device or a knotter device is selected depending on the type of yarn to be used and the required yarn joining mode.
[0024]
The yarn selection device 20 will be described in detail with reference to FIGS. As the yarn guide 21, a yarn guide 21a that guides the yarn Y1, a yarn guide 21b that guides the yarn Y2, a yarn guide 21c that guides the yarn Y3, and the like are arranged by the cylinder 27. By swinging the member 28 with the fulcrum 28a as the center of rotation, the push-up bar 28b disposed at the other end of the swing member 28 comes into contact with the rear guide plate 22B of the thread guide 21 and swings the thread guide 21. The yarn guide position is such that the yarn Y is guided to the yarn joining device 12 (corresponding to 21A in the drawing) and the position where the yarn Y is guided to the suction member 16 (corresponding to 21B in the drawing).
[0025]
The yarn guide 21 has a boss portion 22 and is configured to be rotatable around a rotation shaft 22A. The boss portion 22 is provided with a rear guide plate 22B extending rearward. The yarn guide 21 guides the yarn Y to the yarn joining device 12 by a spring member 23 attached to the rear guide plate 22B. It is configured to bias in the direction of the guide position (corresponding to 21A in the figure).
[0026]
The yarn Y sucked by the suction member 16 is sandwiched between the yarn holding roller 17 and the yarn holding plate 18. The yarn holding roller 17 is a roller member whose outer peripheral surface is coated with an elastic material such as urethane, and the yarn holding plate 18 is configured to abut against and separate from the yarn holding roller 17 by a cylinder 19.
[0027]
When the yarn guide 21 is swinging during the selection of the yarn, the yarn holding plate 18 is separated from the yarn holding roller 17 so that the suction member 16 can suck the yarn Y. When a predetermined yarn is selected and a predetermined yarn guide 21 is positioned at 21A, the yarn holding plate 18 is brought into contact with the yarn holding roller 17 by the cylinder 19 to hold the yarn Y sucked by the suction member 16. Has been.
[0028]
The rear guide plate 22B has a configuration in which a notch is formed at the rear end thereof and the locking piece 24 is locked, and the cylinder 27 guides the yarn guide 21 to the suction member 16 through the push-up bar 28b. When pressed down (corresponding to 21B in the figure), the cylinder 25 causes the locking piece 4 to lock into the notch at the rear end of the rear guide plate 22B, so that the position of the thread guide 21 is brought to the position of 21B in the figure. It is to be fixed. The locking piece 24 is configured to be rotatable by a cylinder 25 with a fulcrum 24A as a rotation center.
[0029]
In the thread switching method, first, the cylinder 27 is slightly extended and the rear guide plate 22B is lifted to release the engagement state with the locking piece 24. Next, only the cylinder 25 corresponding to the selected thread type is driven to move the locking piece 24, so that the locking piece 24 does not come into contact regardless of the position of the rear guide plate 22B. Thereafter, when the cylinder 27 is contracted and the thread guide 21 is rotated by the spring member 23, only the locking piece 24 corresponding to the selected thread type is in a position where it does not engage with the rear guide plate 22B. The yarn guide 21 corresponding to the selected yarn type moves to the yarn guide position (corresponding to 21A in the figure) for guiding the yarn Y to the yarn joining device 12, and the other yarn guide 21 has the locking piece 4 at the rear portion. It is configured to engage with the guide plate 22B and stop at the guide position 21B in the figure.
[0030]
The yarn inserted through the selected yarn guide 21 is in a state where one end thereof is held by the suction member 16, and is indicated by YA indicated by a broken line. The yarn YA is guided in the direction of the yarn splicing device 12 by turning the guide guide 26 in the direction of the arrow in the figure, and the yarn YA is spliced with the yarn Y that has been wound around the yarn length measuring storage device 30 so far. It is configured to start.
[0031]
At this time, the number of selected yarns is not limited to one, and two yarns (for example, yarns Y1 and Y2) may be simultaneously selected and spliced.
[0032]
The yarn length measurement storage device 30 will be described with reference to FIG. When the yarn length measurement storage device 30 is driven and winding is started, the yarn Y having a predetermined length is stored in the storage drum 33. A rotating shaft 32 having a yarn passage 32b along the central axis inside the apparatus main body 31 is rotationally driven by a pulse motor 37 (or a servo motor capable of angle control). The pulley 34 mounted on the rotating shaft 32 is driven to rotate via the pulley 36 and the driving belt 35 disposed in the pulse motor 37, whereby the rotating shaft 32 is rotated and branched from the rotating shaft 32. The winding tube 32 a is configured to turn around the storage drum 33.
[0033]
When the winding tube 32a is driven to rotate around the storage drum 33, the yarn Y inserted through the yarn passage 32b disposed so as to penetrate the winding tube 32a from the central shaft portion of the rotating shaft 32 is Is wound around and stored in a storage drum 33 formed in a tapered shape with a slightly reduced diameter in the traveling direction. Since the yarn Y that has come out of the winding tube 32a is wound around the outer diameter portion of the tapered portion of the storage drum 33, the yarn Y moves toward the front that is slightly reduced in diameter by sliding along the tapered portion. When the yarn Y is wound around the storage drum 33 while the winding tube 32a rotates, the yarn sliding action is continuously performed. Therefore, the yarn Y extends over substantially the entire outer diameter of the tapered portion of the storage drum. Are stored in a state of being arranged in a spiral.
[0034]
The selected yarn length is controlled by controlling the rotation angle of the pulse motor 37 (or a servo motor capable of controlling the angle) by a control device (not shown). Therefore, it is possible to control the length of minute dimensions (1 cm or less). In conjunction with the rotation angle of the pulse motor 37 driven by a control program determined in consideration of the pattern after weaving (corresponding to the yarn length determined in consideration of the pattern after weaving), Since the winding tube 32a rotates by a predetermined angle, the yarn length wound around the storage drum 33 and stored is accurately controlled to the yarn length that forms the pattern after weaving. The presence of the yarn Y stored in the storage drum 33 is performed by a detection sensor such as a photoelectric sensor. In the present embodiment, a leading end detection sensor 39a and a rear end detection sensor 39b are provided.
[0035]
When winding of the yarn Y around the storage drum 33 is started and the leading portion detection sensor 39a detects the yarn Y, the rotational drive of the winding tube 32a is temporarily stopped. When the winding operation is continued in a state where the winding of the yarn Y around the storage drum 33 is stopped and the storage is interrupted, the yarn gradually decreases from the storage drum 33, and the yarn Y is detected by the rear end detection sensor 39b. Therefore, the pulse motor 37 is driven again and the winding by the yarn length measuring storage device 30 is resumed. When the winding is resumed, the wound yarn Y is wound while moving forward toward the slightly reduced diameter so as to slide on the tapered outer diameter portion of the storage drum 33, so that the entire length of the storage portion is again The leading end detection sensor 39a detects the yarn Y.
[0036]
The speed at which the winding tube 32a is rotated to store the yarn Y is higher than the speed at which the winding drum 14 winds up the yarn supply package PW. This absorbs an error between the winding speed of the yarn Y wound by the rotation of the winding drum 14 and the storage speed, and takes into consideration the time for selecting the yarn and the time for splicing. In this configuration, the yarn is stored quickly, so that the winding operation can be continued even while the yarn storage is stopped, the yarn is selected and the yarn is joined.
[0037]
FIG. 5 shows the yarn supply package PW. The package PW is a package in which various colored yarns of the yarns Y1, Y2, Y3,... Are wound in a predetermined order and with a predetermined length to be wound as a single yarn Y. Therefore, as shown in FIG. 5B, a yarn Y having a color distribution such as a red thread having a length L1, a yellow thread having a length L2, a blue thread having a length L3, and a black thread having a length L4 is obtained. be able to. Further, the arrangement is not limited to the color of the yarn, and the arrangement may be such that the thickness of the yarn and the number of components (single yarn, twin yarn, triplet yarn, etc.) are changed. Furthermore, the thread types can be changed and arranged.
[0038]
According to the present invention in which the yarn feeding package PW is used in the partial warping machine 1 shown in FIG. 6, the yarn feeding packages PW1 of various color yarns and yarn types determined in consideration of the pattern after weaving. PW2, PW3,... Are attached to the warping creel 10A and wound up so as to form a band 4 having a predetermined width via a width barb 3. When a band having a predetermined length is formed, the warping drum 2 is moved in the direction of arrow 5 to form the next band. Next, the weaving beam 6 is formed from the partial warping beam 1a having a band having a predetermined number of warps. It is also possible to form a single weaving beam 6 by aligning the warps wound around the plurality of partial warping beams 1a, 1b.
[0039]
Since it is necessary to arrange each yarn feeding package PW1, PW2, PW3... At a predetermined position of the warping creel 10A according to the pattern after weaving, a number corresponding to each creel position is assigned to each yarn feeding package. Configured to grant. By doing so, it is possible to obtain a partial warping beam that correctly reproduces the pattern after weaving, simply by placing the yarn feeding package at a predetermined position of the warping creel 10A according to the number assigned to the yarn feeding package. it can.
[0040]
According to the present invention, by using a yarn feeding package capable of weaving a desired pattern for a partial warping machine, not only is it effective for a small variety of products, but also a small amount of sample fabric can be produced. A suitable warping method can be obtained.
[0041]
According to the first aspect of the present invention, the yarn length of each of various colored yarns and yarn types determined in advance for each yarn supplying package in consideration of the pattern after weaving by the control program is measured. However, by using a plurality of yarn feeding packages wound continuously, it is possible to provide a warping method capable of producing a variety of patterned fabrics, and it is possible to produce a fabric that correctly expresses a desired pattern. .
[0042]
According to the invention which concerns on Claim 2, it can be set as the warping method which can form a partial warp beam by the yarn supply package which has the thread | yarn type and yarn length which express a desired pattern correctly.
