In a weaving cycle, the weft yarn is alternately woven from AB to A8B8, with weft yarns tilted to the right and left at different angles. The weaving production process is repeated in this manner, thereby obtaining a variety of fabric styles.

Description

Technical Field

[0001] The present invention relates to the technical field of looms, and more particularly to a method for weaving fabrics with varying weft density of oblique weft yarns. Background Art

[0002] Loom, also called spinning machine, weaving machine, cotton spinning machine, etc.

[0003] In traditional looms, the weft yarns are woven perpendicular to the warp yarns, and the inclination angle and inclination direction of the weft yarns cannot be changed. It is impossible to change the density and inclination direction of the weft yarns during a weaving process. The weaving style is limited and it is impossible to obtain a variety of fabric styles. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a method for weaving a fabric with varying weft density of oblique weft yarns, so as to obtain diversified fabric styles.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] A method for weaving a fabric with varying weft density of oblique weft yarns, comprising the following steps:

[0007] S1: Determine fabric pattern;

[0008] S2: Install yarn;

[0009] S3: Adjust servo motor parameters;

[0010] S4: Determine the position of the beating point of the beating piece;

[0011] S5: Division of Sutras;

[0012] S6: weft supply;

[0013] S7: Perform beating-up.

[0014] Furthermore, the yarn is first wound on the weaving shaft, then passed around the tension roller and inserted into the first heald frame and the second heald frame, then inserted into the reed, and finally wound onto the take-up roller.

[0015] Furthermore, servo motor parameters corresponding to the desired fabric pattern are input on the input module.

[0016] Furthermore, the information of the input servo motor parameters is transmitted to the control module through the input module, the control module controls the rotation of the servo motor, and then the servo motor drives the screw rod connected to it to rotate, and the rotation of the screw rod drives the slider connected to it to move, and the slider drives the weft beating piece connected to it to move, thereby obtaining the required position of the weft beating point of the weft beating piece.

[0017] Furthermore, the first and second foot pedals respectively drive the connected heald frames one and two to move, so that the heald frames one and two can move up and down, thereby driving the warp yarns passing through them to move, dividing the warp yarns into two layers, forming a shed channel for the weft inserter to pass through, so that the weft yarns can pass through.

[0018] Furthermore, a weft inserter introduces the weft yarn through the shed passage so that the weft yarn and the warp yarn are interwoven.

[0019] Furthermore, the weft yarn is beaten by the beating piece to determine the fixed position of the weft yarn and the warp yarn, thereby obtaining the fabric of the designed pattern.

[0020] Furthermore, the specific steps in S7 are:

[0021] S71: The starting position of the reed is at the straight line O1O2. Each time the reed is beaten, the right side of the reed is moved a certain distance toward the rear of the loom. The beating-up is performed while the reed is being moved. After multiple beating-up, the reed moves a distance S2 to the point O22.

[0022] S72: The left side of the reed moves a certain distance to the rear of the loom after each beating. The reed is moved back and forth several times to beat the weft until the left side of the reed moves a distance of S1 and finally reaches point O11. At this time, the reed is at the position line O11O22, O11O22∥O1O2;

[0023] S73: When the reed reaches the O11O22 position line, the servo motors on the left and right ends must simultaneously reverse rapidly, so that both sides of the reed quickly retreat to the front of the loom to the initial cloth opening O1 O2. Repeat the above steps to complete a section of weaving process, with the weft yarn tilted to the right.

[0024] Furthermore, the specific steps in S7 are:

[0025] S74: The weft yarn is woven from CD to C4D4, completing a cycle of weft yarn beating at a right oblique angle in the fabric. The weft yarn weaving process from C4D4 to C8D8 is exactly the same as that from CD to C4D4.

[0026] S75: The weft yarn is woven from EF to E4F4, completing a cycle of weft yarn beating at a left oblique angle in the fabric. The weft yarn weaving process from E4F4 to E8F8 repeats the weft yarn beating process from EF to E4F4.

[0027] S76: The weft yarn is in a right-slanting state from AB to A4B4, and in a left-slanting state from A4B4 to A8B8. In one weaving cycle, the weft yarn is woven alternately from AB to A8B8 to form right- and left-slanting weft yarns, and the weaving production process is repeated in this way.

[0028] The beneficial effects of the present invention are:

[0029] After the fabric pattern is determined, the yarn is installed on the frame, and then the servo motor parameters are adjusted to determine the position of the beating point of the beating piece. After the warp is separated and the weft is inserted, the beating work is carried out.

[0030] By inputting the servo motor parameters corresponding to the required fabric pattern into the input module, the input module transmits this information to the control module, and the control module controls the operation and operation range of the servo motors at the left and right ends, thereby determining the position of the beating point of the beating piece, and weaving the weft yarn from AB to A4B4 in a right-slanting state, and from A4B4 to A8B8 in a left-slanting state. In a weaving process of one organization cycle, the weft yarn completes the alternating weaving of right and left oblique weft yarns from AB to A8B8, and the weaving production process is repeated in this way, thereby obtaining a variety of fabric styles.

DETAILED DESCRIPTION

[0045] The present invention will now be described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the present invention in a schematic manner, and therefore only shows the components related to the present invention.

[0046] Reference Figures 1 to 6 As shown, the loom 100 of the present invention includes a frame 10 and a weaving shaft 11 arranged at one end of the frame 10, a tension roller 12 is rotatably mounted on the frame 10, and the tension roller 12 is located below the weaving shaft 11, a winding roller 13 is rotatably mounted on the end of the frame 10 away from the weaving shaft 11, and a support frame 14 is also installed on the frame 10. In this embodiment, the support frame 14 is located between the winding roller 13 and the weaving shaft 11.

[0047] A shedding mechanism 15 is provided at one end of the support frame 14 facing the winding roller 13, and the shedding mechanism 15 includes a shedding belt 151 which is sleeved on the support frame 14, one end of the shedding belt 151 is fixedly connected to a heald frame 152, and the other end of the shedding belt 151 is fixedly connected to a heald frame 2 153, the bottom end of the heald frame 152 is connected to a foot pedal 154, and the bottom end of the heald frame 2 153 is connected to a foot pedal 2 155. In this embodiment, the other ends of the foot pedal 154 and the foot pedal 2 155 are both in contact with the frame 10.

[0048] The frame 10 is also equipped with a beating mechanism 16 which is spaced apart from the support frame 14. The beating mechanism 16 is located between the support frame 14 and the winding roller 13. Mounting plates 161 are spaced apart on the opposite mounting sides of the frame 10. The beating mechanism 16 includes a servo motor 162 fixedly mounted on any one of the mounting plates 161. A screw rod 164 is fixedly connected to one end of the servo motor 162. A support plate 163 is fixedly mounted on the other mounting plate 161. The other end of the screw rod 164 is rotatably connected to the support plate 163.

[0049] The loom 100 further includes a control module electrically connected to the servo motor 162, and an input module electrically connected to the control module. In this embodiment, the required servo motor 162 parameters are input into the input module, and the input module transmits this information to the control module, which then controls the range and direction of movement of the servo motors 162 at the left and right ends.

[0050] A slider 165 is movably connected to the screw rod 164 , and a beating piece 166 is rotatably connected to the opposite installation side of the slider 165 , and a reed 167 is installed on the top of the beating piece 166 .

[0051] In the above embodiment, the warp yarn is wound on the weaving shaft 11. The warp yarn first passes through the tension roller 12, then passes through the heddle lifting mechanism 15, and is passed through the beating-up mechanism 16, and finally is wound on the winding roller 13. When passing through the heddle lifting mechanism 15, the warp yarn is successively passed through the heddle frame 152 and the heddle frame 2 153. When passing through the beating-up mechanism 16, the warp yarn is successively passed through the reed teeth of the reed 167 on the beating-up member 166.

[0052] The rotation and direction of the two opposing servo motors 162 mounted on the frame 10 can be controlled to thereby control the rotation and direction of the lead screw 164. The rotation and direction of the lead screw 164 control the sliding stroke and position of the slider 165 on the lead screw 164. The slider 165 then changes the beating operation of the beating member 166, thereby changing the beating point positions at both ends of the beating member 166. As a result, the beating member 166 is tilted left and right during the beating process to obtain weft yarns with different tilt angles, thereby changing the density and tilt direction of the weft and warp yarns interlaced.

[0053] Reference Figures 7 to 11 As shown in FIG, the process flow of the method for weaving a fabric with varying weft density of oblique weft yarns is as follows:

[0054] S1: Determine the fabric pattern; for details, please refer to Figure 11 As shown in the figure, the weft yarns and warp yarns in area a are vertical, and the weft yarns in areas b and c are inclined to the warp yarns. Furthermore, the weft yarns in area b are inclined to the left, and the weft yarns and warp yarns in area c are inclined to the right. Select the required fabric pattern according to the user's own design needs.

[0055] S2: Install the yarn; first, wind the yarn on the weaving shaft 11, then pass it around the tension roller 12, pass it through the heald frame 1 152 and the heald frame 2 153 on the heald lifting mechanism 15, and then pass it through the reed teeth of the reed 167, and finally wind it around the take-up roller 13.

[0056] S3: Adjust the parameters of the servo motor 162; input the parameters of the servo motor 162 corresponding to the designed fabric pattern on the input module.

[0057] S4: Determine the position of the beating point of the beating-up component 166; transmit the input parameter information of the servo motor 162 to the control module through the input module, and the control module controls the rotation and direction of the servo motors 162 at the left and right ends to obtain the desired beating-up point position of the beating-up component 166. Specifically, the servo motor 162 drives the screw rod 164 connected thereto to rotate, and the rotation of the screw rod 164 drives the slider 165 connected thereto to move, and the slider 165 drives the beating-up component 166 connected thereto to move, thereby obtaining the desired beating-up point position of the beating-up component 166.

[0058] S5: Warp separation; the staff steps on foot pedal 1 154 and foot pedal 2 155 respectively, and drives the connected heald frame 1 152 and heald frame 2 153 to move through foot pedal 154 and foot pedal 2 155, so that the heald frame 152 and heald frame 2 153 are lifted and lowered, thereby driving the warp yarns passing therethrough to move, and dividing the warp yarns into two layers, upper and lower, to form a shed channel for the weft inserter to pass through, so that the weft yarns can pass through.

[0059] S6: Weft supply; the weft inserter introduces the weft yarn through this shed channel so that the weft yarn and the warp yarn can be interwoven.

[0060] S7: Beating up the weft; the staff manually swings the beating member 166, and the weft yarn is beaten up by the beating member 166, thereby determining the fixed position of the weft yarn and the warp yarn, and then obtaining the fabric of the designed pattern.

[0061] The specific steps of beating-up are:

[0062] S71: The starting position of the reed 167 is at the straight line O1O2. Each time the reed is beaten, the right servo motor 162 first rotates the right screw rod 164 to drive the right slider 165 to move the right side of the reed 167 toward the back of the loom 100 for a certain distance. The reed 167 is moved while the reed is beaten. After multiple beat-ups, the reed 167 moves a distance S2 to the point O22.

[0063] S72: The left servo motor 162 rotates the screw rod 164 to the left, driving the left slider 165 to move, so that the left side of the reed 167 moves a certain distance toward the back of the loom 100 after each beating. The reed 167 is moved back and forth several times to beat the weft until the left side of the reed 167 moves a distance S1 and finally reaches point O11. At this time, the reed 167 is at the position line O11O22, O11O22|O1O2;

[0064] S73: When the reed 167 reaches the O11O22 position line, the right servo motor 162 and the left servo motor 162 must simultaneously rotate in the opposite direction at a high speed, so that both sides of the reed 167 are simultaneously and quickly retreated to the front of the loom 100 to the initial cloth fell O1 O2. At the same time, the weaving beam 11 and the winding roller 13 synchronously send the warp yarn and the grey fabric to the front of the loom 100 at a high speed by the same distance S (S=S1=S2). Repeat the above steps to complete a weaving process, and the weft yarn presents different inclination angles in the right direction.

[0065] S74: When the reed 167 gradually moves from O1O2 to O1O22, that is, the right side of the reed 167 moves to the rearmost position, the weft yarn changes with the beating position of the reed 167, and the angle between the weft yarn and the warp yarn becomes larger and larger. The weft yarn position changes from CD perpendicular to the warp yarn to C2D2, the maximum right oblique weft yarn. Subsequently, the left side of the reed 167 also gradually moves to the rearmost position, that is, the reed 167 moves from O1O22 to O11O22. At this time, the weft yarn is woven from C2D2 to C4D4, completing a cycle of weft yarn beating at a right oblique angle in the fabric. The weft yarn weaving process from C4D4 to C8D8 is exactly the same as that from CD to C4D4.

[0066] S75: the reed 167 first moves gradually from O1O2 to O2O11, that is, when the left side of the reed 167 moves to the rearmost position, the weft yarn position changes from EF perpendicular to the warp yarn to the maximum left-slanted weft yarn E2F2. Subsequently, the right side of the reed 167 also moves gradually to the rearmost position, that is, the reed 167 moves from O2O11 to O11O22. At this time, the weft yarn is woven from E2F2 to E4F4, completing a cycle of weft yarn beating at a left-slanted angle in the fabric. The weft yarn weaving process from E4F4 to E8F8 repeats the process of the weft yarn from EF to E4F4.

[0067] S76: The weft yarn is in a right-slanting state from AB to A4B4, and in a left-slanting state from A4B4 to A8B8. In one weaving cycle, the weft yarn is woven alternately from AB to A8B8 to form right- and left-slanting weft yarns, and the weaving production process is repeated in this way.

[0068] Reference Figure 8As shown, the weft yarns from AB to A10B10 are successively beaten into the layered and crossed warp yarns by the reed 167. Except for the initial weft yarn AB and the weft yarns A4B4, A8B8, etc. of each subsequent recovery line, the remaining weft yarns have different inclination angles with the warp yarns, either left or right, such as the weft yarns A1 B1, A2B2, A3B3, etc. shown. In a weaving cycle from AB to A8B8, there are weft yarns A2B2 and A6B6 with the rightmost and leftmost inclination angles, and their inclination angles with the warp yarns are ∠B2A2B1 and ∠A6B6A5, respectively, which are the maximum right and left inclination angles of the weft yarns.

[0069] Working principle of the present invention:

[0070] First, the warp yarn is withdrawn from the weaving shaft 11, and then the worker steps on foot pedal 1 154 and foot pedal 2 155 respectively with his feet, and uses foot pedal 1 154 and foot pedal 2 155 to respectively drive the connected heald frame 152 and heald frame 2 153 to move, so that the heald frame 152 and heald frame 2 153 are lifted and lowered, thereby driving the warp yarns passed through them to move, and the warp yarns are divided into two layers, upper and lower, to form a shed channel for the weft inserter to pass through.

[0071] The weft inserter introduces the weft yarn through this shed channel so that the weft yarn and the warp yarn can be interwoven.

[0072] The servo motor 162 is started, and the servo motor 162 drives the screw rod 164 connected to it to rotate. The rotation of the screw rod 164 drives the slider 165 connected to it to move, and the slider 165 drives the weft beating piece 166 connected to it to move. After the position of the weft beating piece 166 is determined, the servo motor 162 stops rotating. Thereafter, the staff pushes the weft beating piece 166 to move, pushes the reed 167 to move and completes the beating motion interwoven with the warp yarn, thereby determining the fixed position of the weft yarn and the warp yarn to obtain the required density and inclination angle between the weft yarn and the warp yarn.

[0073] Beneficial effects of the present invention:

[0074] By automating the beating-up mechanism 16 and starting the servo motor 162, the servo motor 162 drives the screw rod 164 connected thereto to rotate, and the rotation of the screw rod 164 drives the slider 165 connected thereto to move, and the slider 165 drives the beating-up piece 166 connected thereto to move. After the position of the beating-up piece 166 is fixed, the servo motor 162 stops rotating, and then the staff pushes the beating-up piece 166 to move, thereby pushing the weft yarn interwoven with the warp yarn to move, and then determining the fixed position of the weft yarn and the warp yarn to obtain the pattern of the designed fabric.

[0075] During this process, the speed and direction of the servo motor 162 connected to the two ends of the beating member 166 are changed, thereby controlling the movement range of the beating member 166. The beating member 166 can be tilted during the beating process to beat out the weft yarn in an inclined state, thereby changing the density and inclination of the woven weft yarn, and then changing the inclination direction and inclination angle of the weft yarn, thereby obtaining a variety of fabric styles.
