Description

  The present invention provides a sample warping machine having a plurality of yarn guides for winding a yarn around a warping drum, automatically replacing the yarn according to a preset yarn sequence, and winding the yarn on the warping drum. The present invention relates to a sample warper equipped with an anti-spinning mechanism for a yarn guide and a high-speed warping method, which enables extremely efficient replacement of a yarn to be wound by using a plurality of yarn guides.

  As a conventional sample warper, for example, a structure disclosed in Patent Document 1, that is, a fixed creel that stands a plurality of bobbins wound with different types of yarns (different colors or different twists) is used in advance. It is known that a yarn is wound around a warping drum by a yarn guide while the yarn is changed by a yarn selection guide according to set pattern data (yarn order).

  In addition, a rotating creel is used and the yarn changing process is omitted, so there is no time loss during yarn changing, and multiple yarns can be wound around the warping drum at the same time, further reducing the warping work time. Sample warping machines capable of simultaneously warping multiple numbers are also known (Patent Document 2, Patent Document 3 and Patent Document 4).

  The fixed creel has a plurality of bobbins wound with the same type and / or different types of yarn (mainly different types of yarn), and warps each yarn while changing the yarn freely by the selection device. Therefore, there is an advantage that the warping work of the pattern warping can be performed, but there is a disadvantage that it takes much time for the warping work to wind one yarn around the warping drum sequentially. On the other hand, the rotating creel has a plurality of bobbins wound with the same type and / or different types of yarns, and has a solid warp (for example, one color of red yarn), one-to-one (for example, red 1 and white 1). Very limited patterns such as repeat, 1 S twist and 1 Z twist), 2 to 2 (for example, 2 red and 2 white repeats, 2 S twist and 2 Z twist repeats) Can be used for repeated warping. This rotating creel has the disadvantage that it cannot perform the warping work of the pattern warping other than the limited pattern warping, but the warping time is greatly increased because multiple yarns are wound around the warping drum at the same time. There is an advantage that it is shortened.

  The applicant of the present application is a plurality of sample warping machines that support both fixed and rotating creel as a sample warping machine that can reduce the warping time of the warping work that requires plain warping and pattern warping. Sample warping machines in which individual yarn selection devices are provided and a combination of pattern warping and repeated warping have already been proposed (Patent Documents 5 and 6).

  The applicant of the present application has already proposed a novel yarn removal mechanism that can prevent yarn loosening in the above-described sample warping machine and perform efficient yarn replacement (Patent Document 7, Patent Document 8, and Patent Document 9). .

  Conventionally, as described above, prevention of yarn loosening at the time of yarn replacement in a sample warper has already been studied and improved. By the way, the yarn exchange using the fixed creel of the current sample warping machine (that is, supplying yarn from the yarn selection guide to the yarn guide or storing yarn from the yarn guide to the yarn selection guide) is one yarn guide. In this sample warping machine, one yarn guide is used, and in a sample warping machine having a plurality of yarn guides, one yarn guide to be used is selected, and only one yarn guide is used. It was done.

  In such a sample warper, for example, when changing a red thread to a white thread, the red thread is removed from one yarn guide, the red thread is stored in a red thread selection guide, and the white thread In order to supply white yarn from the yarn selection guide to the yarn guide, the yarn guide had to idle at least once during the period from storage of the yarn to supply of the yarn.

In recent years, as the design of the woven fabric becomes more complicated, the number of times of yarn exchange has become very large, and the total idle rotation time of the yarn guide at the time of yarn exchange has increased in proportion to the time required for warping work. Therefore, there is a demand for a yarn changing mechanism that minimizes the idle time of the yarn guide.

And a yarn selecting device 27 provided with a plurality of yarn selection guides 27a to 27j that are rotated and protruded to the yarn changing position when the yarn is changed and are turned and stored at the standby position when the yarn is stored. By transferring the yarn 22 between the yarn guides 6a to 6h and the yarn selection guides 27a to 27j, the yarn 22 is automatically transferred according to the set yarn order. In which winding the yarn 22 above. Reference numerals 7a to 7h denote guide pieces, which are provided at the tip ends of the yarn guides 6a to 6h, and act to hold and hold the yarn.

  In FIG. 1, 79 is a controller, 212 is a thread changing portion, 214 is a side cover, 216 is a viewing window, and 218 is a driving portion.

  As shown in FIGS. 1 and 2, in the sample warper 200 of the present invention, there are a plurality of fixed creels 202 for standing a plurality of bobbins 110 wound with different types of yarns (yarns of different colors or different twists). The yarn selection guides 27a to 27j are respectively installed.

  The yarn 22 of the fixed creel 202 is stored in a plurality of yarn selection guides 27a to 27j, respectively, and the yarn 22 of the fixed creel 202 can be wound around the warping drum 208 sequentially.

  The fixed creel 202 includes a bobbin stand 102 and a creel stand 104. The bobbin stand 102 has a bobbin frame 108 having casters 106 on the lower surface. An appropriate number of bobbins 110 are attached to the rear end side of the bobbin frame 108. A guide plate 112 is provided in front of the bobbin 110.

  As shown in FIG. 1, the warping yarn 22m has its tip wound around the warping drum 208 via the yarn guide 6, so that the yarn tension fluctuates, and the drop ring 124 also moves up and down accordingly. Move. On the other hand, in the case of a thread 22n that is at rest (yarn stored in the thread selection device 27), the drop ring 124 is stored in the yarn selection device 27 in a state of dropping downward.

  A conveyor belt 17 is set so as to be movable on the peripheral surface of the warping drum 208. The conveyor belt 17 is fed by a conveyor belt feeding means according to the warping conditions (the number of warps, the warping width, the number of warping windings, etc.). The amount is controlled and its movement is synchronized with the rotation of the yarn guide. Reference numerals 33, 34, 38a and 38b are weiring bars, and 35 and 37 are cut weiring bars. The weiring means (not shown) are arranged on the yarn guide side tip of these weiring bars 33 to 35, 37, 38a and 38b. The yarn twill can be formed by the twilling means. Note that the basic configuration and operation of the sample warper 200 are widely known from the above-mentioned patent publications and the like, and detailed description thereof is omitted.

  As the above-described yarn selection device 27, one described in Patent Document 7, for example, the one shown in FIGS. 4 and 5 may be used. 4 and 5, the yarn selection device 27 has a plurality of yarn selection guides 27a to 27h (27d to 27f are shown in FIG. 4 and 27a is shown in FIG. 5). The yarn selection guides 27a to 27h are rotated by the selection solenoid 29, which is a corresponding rotary solenoid, to the operating position (yarn exchange position) and the standby position (yarn storage position), respectively, so that the yarn 22 is taken in and out. To do.

  Yarn removal guides 136a to 136h (in the illustrated example, 136e to 136g are shown in FIG. 4 and 136a is shown in FIG. 5) are provided so as to be paired with the above-described yarn selection guides 27a to 27h. Yes. The thread removal guides 136a to 136h are rotated to an operating position (thread removal position) and a rest position (standby position) by a thread removal solenoid 138 installed in the vicinity of the select solenoid 29, and perform a thread removal operation. . 4 and 5, 16 is a drum spoke, 59 is a front cover, 59a is a front guide rod, and 212 is a thread changing portion.

  As the thread selection device 27, in addition to the one shown in FIGS. 4 and 5, a structure in which a conventionally known thread removal member is provided separately can be used.

  A fixed yarn guide can be used as the plurality of yarn guides 6a to 6h, but a movable yarn guide is preferably used. As the movable yarn guide, one described in Patent Document 10, for example, the one shown in FIGS. 6 and 7 may be used. The movable yarn guides 6a to 6h are rotatably provided at the arm portion 308 and the distal end portion of the arm portion 308, as shown in FIGS. 6 and 7 (representatively showing the movable yarn guide 6a). And guide pieces 7a to 7h capable of holding the yarn.

  A holder portion 312 is provided at the distal end of the arm portion 308, and a cylinder base 314 is connected to the holder portion 312. A rotary air cylinder 316 is attached to the cylinder base 314. The rotary air cylinder 316 has a swing shaft 316a, and a guide piece 7a is fixed to the swing shaft 316a. It rotates with the movement. Reference numerals 318a and 318b denote air tubes that are connected to the rotary air cylinder 316 and supply compressed air into the rotary air cylinder 316 from a solenoid valve (not shown).

  For example, when compressed air is supplied from the air tube 318a into the rotary air cylinder 316, the guide piece 7a rotates in one direction, for example, the solid line position in FIG. 7, that is, protrudes to the yarn holding position and functions as a yarn guide. Fulfill. On the other hand, when compressed air is supplied from the air tube 318b into the rotary air cylinder 316, the guide piece 7a rotates in the other direction, for example, the phantom line position in FIG. Does not serve as a guide. In FIG. 7, reference numerals 320 and 320 indicated by phantom lines are stoppers that serve to limit the rotation range of the guide piece 7a.

  The sample warping machine of the present invention includes a plurality of yarn guides 6a to 6h for winding the yarn 22 around the warping drum 208, and the yarn guides 6a to 6h at one end of a base 210 that supports the warping drum 208. And a plurality of thread selection guides 27a to 27j that rotate and protrude to the thread replacement position when the thread is replaced and that are rotated and stored at the standby position when the thread is stored, Each of the yarn guides 6a to 6h, and each yarn selection guide 27a. The yarn guides 136a to 136j are provided one by one corresponding to the plurality of yarn selection guides 27a to 27j. The yarn is transferred to and from 27j to automatically replace the yarn 22 and wind the yarn 22 on the warping drum 208 in accordance with a preset yarn order. The characteristic feature is that the first yarn guide (for example, 6a) that winds the first yarn (red), for example, 22a, on the warping drum 208 when the yarn is replaced is replaced with the first yarn guide (for example, 6a). Of the two yarn guides 6a and 6b, the yarn removing operation for removing the first yarn 22a and the yarn supplying operation for supplying the second yarn (white), for example, 22b to the second yarn guide 6h, are performed first. This is performed during one rotation of the reference yarn guide that is the target of the yarn removing operation or yarn supplying operation.

  The mode of thread replacement in the present invention is as follows: (1) the above-mentioned yarn removing operation can be performed after the above-described yarn removing operation, and (2) the above-mentioned yarn removing operation can be performed after the above-described yarn supplying operation. Further, (3) the yarn removing operation and the yarn supplying operation can be performed simultaneously.

  (1) When the yarn feeding operation is performed after the yarn removing operation, for example, the yarn 22a is removed from the first yarn guide 6a around which the first yarn 22a is wound, and the second yarn guide 6b is The second thread 22d is caught as follows. First, the first yarn 22a is wound from the first yarn guide 6a winding the warp drum 208 on the warp drum 208, for example, the first yarn 22a is hooked and removed from the yarn guide 6a. Deliver and store. Next, the empty first yarn guide 6a (in this case, the first yarn guide 6a is the first yarn removal target, and the first yarn guide 6a is the reference yarn guide). The second yarn 22d is supplied to the second yarn guide 6b from the yarn selection guide 27d storing the second yarn 22d, and the second yarn 22d is supplied to the second yarn guide. It is wound around the warping drum 208 while being held at 6b. If such a yarn exchange is performed, the time until the first yarn 22a is removed from the first yarn guide 6a and then the second yarn 22d is held by the second yarn guide 6b is extremely short. Thus, the idle rotation state of the yarn guide (the state where none of the yarn guides 6a to 6h holds the yarn 22) is avoided as much as possible.

In the case of the above (1), as the second yarn guide, if the yarn guide that first passes after the yarn selection guide 27d enters the state of supplying the second yarn 22d is used, the first yarn guide is empty. Thus, the idling time of the first yarn guide 6a can be minimized. As the second yarn guide, one provided adjacent to the first yarn guide 6a that has been emptied in the downstream in the rotational direction of the yarn guide, 6b in the case of FIG. 3, is used. Is most preferable because the idling time can be minimized. However, in order to be able to use the yarn guide 6b as the second yarn guide, as shown in FIG. 8, the length L _{1 of the} arc formed by the yarn guide 6a and the yarn guide 6b is determined by the yarn selecting device 27. than installation width L _a (i.e. installation width L _a of all of the yarn selection guide 27A～27j) large, i.e. L _1> is required to be a L _a. If, in the case of L ₁ <L _a, since it can not use a yarn guide 6b as a second yarn guide, an arc length L ₂ that is formed further by the yarn guide 6a and yarn guide 6c yarn compares is greater than the installation width L _a selection device 27, L _2> if L _a yarn guide 6c can be used as the second yarn guide. If L ₂ <L _a becomes possible to select and use a yarn guide forming a larger arc as well. In practice, the installation width of the yarn selection guides 27a to 27j to be used first and the yarn selection guides 27a to 27j to be used next, for example, L _d (in the example of FIG. 8, the installation widths of 27a and 27d are shown). the advantage with the above L _1, but the relationship of L ₂ can be performed if L _1, L _2> L _d, the availability of all the yarn selection guide 27a~27j if set to L ₁ or L _2> L _a There is.

  More specifically, in the case of (1), for example, the yarn warped by the first yarn guide 6a is, for example, the yarn of the yarn selection guide 27a (22 m in the example of FIG. 2). In some cases, any of 6b-6h can be used as the second yarn guide, but 6b is most preferred. As the yarn supplied to the second yarn guides 6b to 6h, any of the yarns (22n in the example of FIG. 2) stored in the yarn selection guides 27b to 27h can be used. As described above, in the case of (1) in which the yarn is exchanged from the yarn guide 6a to the yarn guide 6b, the yarn guide 6a is idled compared to the case where the yarn is exchanged after the conventional yarn guide 6a is idled once. The idling of 1/8 rotation is sufficient.

(2) When the yarn removing operation is performed after the yarn supplying operation, for example, the first yarn 22a is caught by the empty second yarn guide 6a and the first yarn 22d is wound around the first yarn 22d. When the yarn 22d is removed from the yarn guide 6b, the operation is as follows. First, the second yarn 22a is supplied to the second yarn guide 6a rotating in the sky, and the second yarn 22a is held by the second yarn guide 6a and wound around the warping drum 208. Then, the second yarn guide 6a (in this case, the first yarn guide is the second yarn guide 6a, and the second yarn guide 6a becomes the reference yarn guide) makes one rotation. In the meantime, a first yarn guide 6b winding the first yarn 22d on the warping drum 208 is removed from the yarn removal guide, for example, 136d by hooking the first yarn 22d to the corresponding yarn selection guide. Delivered to 27d and stored. Even when such a yarn exchange is performed, the time until the second yarn 22a is supplied to and held by the second yarn guide 6a and the first yarn 22d is removed from the first yarn guide 6b is extremely long. It is a short time, and the idle state of the yarn guide is avoided as much as possible. In the case of (2), it is preferable that the yarn selection guide storing the yarn to be supplied first is positioned upstream in the rotational direction of the yarn guide. While in the case of this configuration it is necessary that the second yarn guide 6a located upstream in the rotation direction of the yarn guide than the first yarn guide 6b, the width L _a and yarn guide 6a of the selector 27 The size of the arc widths L ₁ and L ₂ between ˜6h does not matter. Even in the case of (2), it is also possible to adopt a configuration in which the yarn selection guide storing the yarn to be supplied first is located on the downstream side in the rotation direction of the yarn guide. In this configuration, in order to remove the second yarn 22d from the first yarn guide 6b, the above-described L ₁ or L ₂ > L _d is sufficient, but L ₁ or L ₂ > L Once you have with _a there is an advantage of being able to use all of the yarn selection guide 27a~27j in the same way.

  More specifically, in the case of (2), for example, if the yarn warped by the first yarn guide 6b is, for example, the yarn of the yarn selection guide 27h, the second yarn guide is 6a is preferably used. As the yarn supplied to the second yarn guide 6a, any yarn stored in the yarn selection guides 27a to 27i excluding the yarn selection guide 27h can be used. Thus, in the case of (2) in which the yarn is exchanged from the yarn guide 6b to the yarn guide 6a, the yarn guide 6b is idled compared to the case where the yarn is exchanged after the conventional yarn guide 6b is idled once. The last 1/8 rotation is in a state where both yarn guides 6a and 6b wind the yarn (so-called two windings), but such two windings are a problem in warping work. There is nothing.

(3) When the yarn removing operation and the yarn supplying operation are performed simultaneously, for example, the yarn 22a is removed from the first yarn guide 6a around which the first yarn 22a is wound, and the second yarn guide 6b is used as the second yarn. When catching 22d, it is as follows. The first yarn 22a is also wound on the warping drum 208. The yarn removal guide, for example, the first yarn 22a is hooked and removed from the yarn guide 6a, for example, 136a, and is transferred to the corresponding yarn selection guide 27a. And store. At the same time, the second yarn 22d is supplied from the yarn selection guide 27d for storing the second yarn 22d to the second yarn guide 6b, and the second yarn 22d is held by the second yarn guide 6b. In this state, it is wound around the warping drum 208. In this case, installation width L _d of the first yarn guide 6a and the second width of the arc L ₁ formed by the yarn guide 6b and the yarn selection guide 27a and 27d is, the yarn 22a first yarn guide 6a It is necessary that the yarns 22d are substantially coincident so that the yarn 22d can be fed to the second yarn guide 6b, that is, L ₁ = L _d .

  In the case of the above (3), in addition to the arrangement of the thread selecting device 27 shown in FIGS. 3 and 8, as shown in FIG. 9, the thread selecting device 27 is divided into a plurality of groups (FIG. 9). In this example, it is preferable to employ a first yarn selection device 27A and a second yarn selection device 27B. The first yarn selection device 27A includes yarn selection guides 27a to 27e, and the second yarn selection device 27B includes yarn selection guides 27f to 27j. Then, the installation angle between the two yarn selection devices 27A and 27B is an angle formed by the yarn guides 6a to 6h (in the case of eight yarn guides, the adjacent yarn guides, for example, 6a and 6b). If the angle to be formed is set equal to 45 ° (45 ° in the case of FIG. 9), the distance between the yarn guides 6a and 6b and the distance between the yarn selecting devices 27A and 27B can be matched. With such a configuration, it is easy to simultaneously perform the yarn removing operation from the yarn guide 6a and the yarn supplying operation to the yarn guide 6b as in the case of (3). As described above, when the yarn removing operation and the yarn supplying operation are performed simultaneously, the idle rotation of the yarn guide 6a is completely eliminated, and an ideal yarn replacement is performed. Even when the yarn selecting device 27 is divided into groups as shown in FIG. 9, the yarn removing operation and the yarn supplying operation are sequentially performed as in the cases (1) and (2) described above. Of course, it can be applied.
