Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method and apparatus for arranging and warping pile yarns used in multicolored patterned pile fabrics.

[Prior Art and Problems to be Solved] Traditionally, there have been patterned pile fabrics such as multicolored carpets produced by Axminster looms as multicolored patterned pile fabrics. The more colors there are, the more time and manpower are required to prepare the pile yarn used, making it unsuitable for small-lot production.

For example, in the case of a jacquard-type Axminster loom that uses a jacquard device to select pile yarns, multiple pile yarns to be used for this are introduced into each pile row in the weaving direction of the patterned pile fabric. Special carries are installed in parallel, and each carry for each pile row in the weaving direction is moved up and down appropriately with a jacquard for each weaving, and the necessary pile yarns are lined up in a horizontal line at a predetermined position, and then the pile length is adjusted using a gripper. The material is picked out and cut to a length corresponding to , and then carried to the weaving area and woven into it. In this case, each pile yarn introduced into each carry in parallel in the weaving width direction is usually wound around a cheese and hung on a creel at the rear of the loom.

In this case, a plurality of pile yarns (about 12 colors at most) are guided to each carry in each pile row in the weaving direction, so the larger the number of colors, the wider the weaving width. The larger the creel, the more cheeses will be hung on the creel stand. For example, 12,000 cheeses will be needed to weave a 4m wide patterned pile fabric with 12 colored patterns. As a result, the creel stand becomes larger and the installation space behind the loom becomes larger, and it takes a lot of effort to prepare and set up the cheese and jacquard. As a result, in the case of high-mix, low-volume production of sample fabrics, etc., efficiency is poor and costs are extremely high.

In addition, the spool-type Axminster loom, as schematically shown in Figure 8, arranges each pile thread into a beam in accordance with the pile thread arrangement in the weft direction according to the pattern for each pile weave. Prepare spools S which have been warped and wound in a pile weaving number (number of stages) corresponding to one repeat of the pattern in the weaving direction, and move the number of spools S corresponding to one repeat into an endless rotating chain. Weaving is carried out by hanging each pile yarn P in the weaving direction in order of the weaving direction on a supply transfer means C such as the above, and supplying each weave sequentially to the front of the weaving opening, cutting each pile yarn P to a certain length from this spool S and weaving it. It is.

According to this spool method, the number of colors is unlimited, and pattern piles of 20 to 30 colors are usually woven.As a preparatory work, a large number of spools S corresponding to the number of pile weaving stages for one repeat are woven. A large number of pile yarns must be arranged and warped in accordance with the pile yarn arrangement in the weft direction (weaving width direction) according to each pattern, and this work requires a great deal of labor and time. For example, in the case of a 4m width, it takes 4 people 10 days to make it, which is extremely costly in the case of high-mix, low-volume production.

Moreover, since the spool S is made of a beam with a relatively large diameter, when it is used by hanging it on an endless transfer means such as a chain, there is a problem that the transfer means C becomes quite long. be.

In view of the above, the present invention has been developed by arranging pile threads, which are mainly used in weaving multicolored patterned pile fabrics using an Axminster loom, in the same manner as the conventional spool method, and pulling out one end using a special thread holding section. We decided to warp the pile yarn into a sash-like shape that could be held as much as possible, and this was done to simplify and streamline the warping work and also to make it possible to downsize the means for supplying and transporting the pile yarn in the loom. The present invention provides a method for arranging and warping pile yarn and an apparatus for achieving this.

[Means and effects for solving the problems] In the array warping method of the present invention that solves the above problems, each of the plurality of types of pile yarns used in the patterned pile fabric is mechanically or electrically actuated. The selection means that performs a predetermined selection operation is held so that it can be pulled out, and the selection means performs a predetermined selection operation.
In accordance with the arrangement order of the pile yarns in the weft direction for each weave in the patterned pile fabric, the corresponding pile yarns are sequentially selected, and in response to this selection action, the selected pile yarns are pulled out. Almost at the same time as the action is completed, the pulled-out pile yarn is transferred to the yarn-holding part of a rod-shaped yarn-holding member in which a large number of yarn-holding parts that can pull out and hold the pile yarn in one direction are arranged in parallel. It is characterized in that the drawer-side end portions of the pile threads are successively inserted through the threads to hold them so that they can be drawn out in one direction, and the pulled-out pile threads are cut to a certain length.

By doing the above, pile yarns are selected corresponding to the pile yarn arrangement in the weft direction for each weaving of the patterned pile fabric, and the arrangement is adjusted by pulling out, holding with a rod-like yarn holding member, etc. Warp work can be performed mechanically and easily and continuously. Furthermore, each of the pile yarns arranged in this way is held in a sash shape with the ends thereof removably held by a rod-shaped thread holding member, and is well and reliably held in a predetermined arrangement and warping state, unlike conventional spool yarns. There is no need to wrap the pile yarn around the beam as in the case of the above method, and it becomes possible to use the pile yarn as it is by equipping it to a weaving machine such as an Axminster loom.

Further, the invention according to claim 2 relates to an array warping apparatus used for carrying out the method, and has the following configuration.

In other words, the device of the present invention has a plurality of yarn guide portions that hold a plurality of types of pile yarns so that they can be pulled out in one direction, and a pattern is created by sequentially performing a predetermined selection operation by mechanical or electrical means. A pile yarn selection means is provided for moving a guide portion of a corresponding pile yarn to a selection position in accordance with the arrangement order of the pile yarns in the weft direction for each weave of the pile fabric. Further, on the pile yarn drawing side of the selection means, the selection means is provided so as to be movable back and forth in the direction of distance from and near the selection position, and in response to the selection action, the end of the pile yarn protruding from the selected yarn guiding section is moved. It includes a pulling means that can be grasped and pulled out a certain length, and a means that performs a cutting operation in the vicinity of the selection position in response to the pulling action, and cuts the pulled out pile yarn. Further, a large number of yarn holding parts capable of holding the pile yarn so as to be drawn out only in one direction are arranged in parallel in one row, and the yarn holding portions are arranged in parallel in a row, and the yarn holding portions are arranged in parallel in a row, and the yarn holding portions are arranged in parallel in a row, and the yarn holding portions are arranged in parallel in a row, and the yarn holding portions are arranged in parallel in a row, and the yarn holding portions are arranged in parallel in a row, and the yarn holding portions are arranged in parallel in a row, and the yarn holding portions are arranged in parallel in a row, and the yarn holding portions are arranged in parallel in a row, and the yarn holding portions are arranged in parallel in a row. A rod-shaped thread holding member is fed at intervals of holding parts, and the thread holding member is disposed above the pile thread pulling position so as to correspond to the thread holding member, and the drawing side end of the pile thread is connected to the thread holding member. The thread insertion means is inserted into the thread holding part so as to be able to be pulled out in one direction.

In the case of this arranging and warping device, a plurality of types of pile yarns to be arrayed used in a patterned pile fabric are guided to a predetermined yarn guiding portion of the selection means and held in a state where the ends protrude. Then, this pile yarn selection means sequentially performs a predetermined selection operation mechanically or electrically, and selects the corresponding pile yarns according to the arrangement order of the pile yarns in the weft direction for each woven fabric in the patterned pile fabric. The thread guide portions of the thread are sequentially moved to the selection position.

In addition, in response to this selection action, a pull-out means with a gripper disposed on the pile thread pulling side moves in the approaching direction with respect to the selection position of the selection means, and the pile protruding from the selected thread guide section is moved toward the selection position of the selection means. The end of the yarn is gripped by the gripper section, and in this state, the pulling means moves in a direction away from the selection position in the opposite direction to the above, thereby pulling out the selected pile yarn for a certain length. The pile yarn pulled out in this way crosses the yarn holding member fed in a direction perpendicular to the pulling direction slightly below the pile yarn, and becomes in a state corresponding to one of the yarn holding parts included in the yarn holding member.

Under this condition, the insertion means located above the intersection between the pile yarn pulling out position and the yarn holding member operates, pushes down the end of the pulled out pile yarn, and causes the end of the pile yarn to be gripped and held by the gripper part of the pulling out means. Release the end and insert the end into the corresponding thread holder. The pile yarn inserted in this way is held so that it can be pulled out only in one direction. Simultaneously with the insertion and holding action, the cutting means performs a cutting operation to cut the pile yarn in the vicinity of the selection position.

In this way, the selection operation of the pile yarn by the selection means and the pulling-out operation of the pile yarn by the corresponding pull-out means are sequentially repeated, and correspondingly, the rod-shaped yarn holding member is moved by the yarn holding portion size as described above. By moving the pulled-out pile yarn in a direction perpendicular to the pulling-out direction and passing the pulled-out side end of the pulled-out pile yarn through each yarn holder in sequence and holding it, the pile yarn in the weft direction for each weave of the patterned pile fabric is This means that the pile yarns can be warped in an arrangement that corresponds to the yarn arrangement, and that the ends of each pile yarn are held by the yarn holding member to form a sash-like shape.

[Example] Next, embodiments of the present invention will be described with reference to the drawings together with the apparatus used.

FIG. 1 schematically shows an array warping apparatus used in the method of the present invention.

In the figure, reference numeral 1 denotes means for selecting pile yarns p of many colors and types to be used in patterned pile fabrics. This selection means 1 utilizes the structure of the pile yarn selection carry of the conventional Axminster loom using the jacquard method, and selects a plurality of types (for example, 30 pieces) of pile yarns p led from the cheese in a state where the ends thereof normally protrude. It consists of a plurality of thread guiding parts 1a arranged in parallel and held so that they can be pulled out in one direction. For example, when they are arranged vertically in parallel as shown in the figure, the upper end is connected to a well-known jacquard device and the upper and lower ends are connected to each other. It is movably suspended and moved up and down by the jacquard device to perform a predetermined selection operation, and the guide portion 1a of the pile yarn p corresponds to the arrangement order of the pile yarns in the weft direction for each weave in the patterned pile fabric. is configured to move to a preset selection position B.

Note that this selection means 1 can perform the selection operation not only by mechanical means such as the Jiacard device as described above, but also by electrical means such as a pulse motor or servo motor that operates in response to commands from a microcomputer. It is also possible to configure and implement such a selection operation. It is only necessary to move the yarn guiding portion 1a to a predetermined selection position, and in particular, the yarn guiding portions 1a may be arranged in horizontal rows or double rows.

Reference numeral 2 denotes a pull-out means with a gripper provided on the pull-out side of the pile yarn p of the selection means 1 so as to be movable back and forth in the distance direction with respect to the selection position B by an appropriate driving means; The selected yarn guide portion 1 corresponds to the selection action of
The end portion p1 of the pile yarn protruding from the gripper portion 21 is gripped by the gripper portion 21 and is provided so that it can be pulled out for a certain length. After pulling out the pile yarn p, the gripper portion 21 releases its gripping action when inserting the yarn into a thread holding member, which will be described later.

Reference numeral 3 denotes a cutting means such as a cutter disposed near the selection position B in the selection means 1, and performs a cutting operation in response to the pulling out action of the pile yarn p by the pulling means 2, so that the pile yarn p is pulled out. It is provided to cut the pile yarn p. usually,
This cutting action is configured to be performed substantially simultaneously with the completion of insertion into the thread holding member, which will be described later.

Reference numeral 4 denotes a thread holding section which is a rod-shaped body having a predetermined length, in which a large number of thread holding sections 41 capable of holding the pile yarn p so as to be pulled out in only one direction are arranged in a row. (p) A means that is fed in a direction perpendicular to the drawing direction from behind at a position slightly below the drawing position near the drawing end in the drawing state, and is moved appropriately in the feeding direction by the size of the yarn holding section 41 for each drawing operation of the pile yarn. (not shown), and in a stopped state, one yarn holding section 41 is provided so as to correspond to the lower part of the pull-out position of the pile yarn p. 42 is its movement guide.

As shown in the figure, this thread holding member 4 has holding spaces 45 opened on both sides with predetermined spacers 44 interposed at predetermined intervals in the length direction between two opposing long plates 43, 43. A bent plate-shaped spring 46 is installed in each space 45.
and a receiving part 47 are provided inside the opening, so that the pile yarn p can be inserted from one side of the opening, and can be held so as to be pulled out only from the other opening side, with the insertion side opening facing upward. will be delivered.

Further, in the case where the weaving width of the patterned pile fabric is relatively narrow, up to about 2 m, the thread holding member 4 can be formed to have a length corresponding to the weaving width. It is desirable to divide the entire length of one weave into a plurality of lengths in the width direction, depending on the necessity, such as in the case of a relatively wide width as described above.

Reference numeral 5 denotes a yarn insertion means disposed above the intersection of the yarn holding member 4 and the pile yarn pulling-out position so as to correspond to the yarn holding member 4, and
The drawer side end p1 of the thread holding member 4 is inserted into the corresponding thread holding portion 41 of the thread holding member 4 by pushing it therethrough. For example, it is equipped with a push pin 51 that moves forward and backward in the vertical direction by a cylinder mechanism such as an air cylinder or a cam or crank mechanism, and after the pile yarn is pulled out, the push pin 51 advances and the pile yarn p is transferred to the corresponding yarn holding section. 41 so as to be inserted and held therein.

When carrying out the present invention using the above-mentioned apparatus, plural types of pile yarns p to be arranged used in patterned pile fabrics are selected from a predetermined yarn guide section 1a in the selection means 1.
and hold it with the end protruding. Then, this pile yarn selection means 1 sequentially performs a predetermined selection operation mechanically or electrically to match the arrangement order of the pile yarns in the weft direction for each weave in the patterned pile fabric. The yarn guide portion 1a of the pile yarn p is sequentially moved to the selection position B.

In addition, in response to this selection action, the gripper-equipped pull-out means 2 disposed on the pile yarn pull-out side moves in the direction approaching the selection position B of the selection means 1, and moves from the selected yarn guide section 1 The end p1 of the protruding pile yarn p is gripped by the gripper part 21, and in this state, the pulling means 2 moves in a direction away from the selection position B, contrary to the above,
As a result, the selected pile yarn p is pulled out to a certain length (FIGS. 1 and 2). This drawing length can be arbitrarily determined by the reciprocating stroke of the drawing means 2.

A rod-shaped yarn holding member 4 is fed slightly below the pile yarn p pulled out in this way in a direction perpendicular to the pulling direction, and the pile yarn p is held horizontally in correspondence with one yarn holding portion 41. state.

Under this state, the insertion means 5 located above the intersection between the pile yarn pulling out position and the yarn holding member 4 operates to push down the end p1 of the pile yarn p that has been pulled out, and at the same time push down the end p1 of the pulled out pile yarn p. 21 and release the end p1 held by the third
(Fig. 4), the end portion p1 is pushed into and inserted into the corresponding thread holding portion 41 (Fig. 4). The pile yarn p inserted in this way is held so that it can be pulled out only in one direction. Simultaneously with the above-mentioned insertion and holding action, the cutting means 3 performs a cutting operation to cut the pile yarn p in the vicinity of the selection position B.

In this way, the selecting action of the pile yarn p by the selection means 1 and the corresponding action of pulling out the pile yarn p by the pulling means 2 are repeated sequentially, and correspondingly, the yarn holding member 4 is moved from the yarn holding part 41. By moving the end portion p1 of the pulled-out pile yarn p by size in a direction perpendicular to the pulling-out direction, and sequentially inserting and holding the end portion p1 of the pile yarn p into each yarn holding section 41,
The arrangement corresponds to the pile yarn arrangement in the weft direction for each woven portion of the patterned pile fabric, and the end portion p1 of each pile yarn p is held by the yarn holding member 4 to arrange it in a special form in the form of a blind. You will be able to go through this process.

Therefore, as shown in Fig. 7, the arrayed pile yarn P thus arranged and warped is fed by an endlessly rotating chain or the like, similar to the spool system in a patterned pile fabric weaving machine such as an Axminster loom. The rod-like yarn holding members 4 are suspended on the transfer means C in sequence, and the ends of each pile yarn p of each array body P are sequentially transferred to the front of the weave in accordance with the weaving operation, thereby changing the pile length. By pulling out and weaving a predetermined length corresponding to the length, a patterned pile fabric can be woven. In particular, the pile yarn array P has a sash-like shape, and
The thread holding member 4 is also relatively narrow in width compared to a conventional spool, so the distance between each array P, P can be made smaller than before, and the transfer means C can be shortened accordingly, and a large number of arrays C can be suspended. This makes it possible to weave multicolored pile patterns with large repeat lengths. Further, the length of the pile yarn p held by the yarn holding member 4 can be shortened, and it can be suitably used for weaving relatively short pile fabrics such as sample fabrics.

Furthermore, if the pile yarn array P is in the form of a blind with one end of each pile yarn p held by the rod-shaped yarn holding member 7, the array P for one reveal can be , it is possible to weave by stacking one after another to form a cassette shape, which is moved up and down sequentially one step at a time from the top and bottom in front of the weaving mouth of the weaving machine, supplying each pile yarn, making it even more bulky. can.

[Effects of the Invention] As described above, according to the array warping method and apparatus of the present invention, it is possible to select, pull out, and select pile yarns corresponding to the pile yarn array in the weft direction for each weave in a patterned pile fabric to be woven. Array warping work such as holding by thread holding members can be performed mechanically and easily and continuously, and the work does not require human labor.
Moreover, automation becomes possible easily. Furthermore, even if the number of colors in the pile increases, it can be mechanically arranged and warped in the same way as described above.

Furthermore, each of the pile yarns arranged in this way is held in a sash shape with the ends thereof removably held by a rod-shaped thread holding member, and is well and reliably held in a predetermined arrangement and warping state, unlike conventional spool yarns. There is no need to wrap it around the beam as in the case of , making it less bulky and easier to handle. In particular, when the thread holding member is used to weave a patterned pile fabric by equipping it to a weaving machine such as an Axminster loom as is, the spacing between the pile thread arrays is set to be smaller than in the case of the conventional spool method. It is possible to make it smaller,
The supply and transfer means for the pile yarn can be shortened accordingly,
It also becomes possible to weave large pile fabrics by making each repeat of the pattern longer than before.

Therefore, the present invention can contribute to streamlining and automating the warping preparation work of pile yarns in weaving pile fabrics, and can be suitably used for high-mix, low-volume production of patterned pile fabrics, thereby reducing costs. I can do it.
