Description
Technical Field
[0001] The utility model belongs to the technical field of industrial automation and mechanical control, in particular to a flat wire radial unwinding device based on tension sensor control. Background Art
[0002] In traditional rapier looms, the weft yarn is unwound from the weft yarn bobbin along the axial line of the weft yarn bobbin. Generally, it passes through the weft storage device, the weft yarn detector, and the weft selector and is clamped by the weft sword to start weft insertion. The weft yarn is unwound axially along the weft yarn bobbin, which will cause the weft yarn to be twisted. The extra twist on the weft yarn generally does not affect the quality of the fabric. The rotation direction of the weft storage device can be adjusted to reduce the amount of extra twist, or a special "twist-free" weft storage device can be added to eliminate the extra twist on the weft yarn. However, the above method cannot guarantee that the twist on the axially unwound weft yarn is completely eliminated. For flat weft yarns (such as flat silk, flattened carbon fiber, etc.), if the weft yarn is not allowed to have twist on the fabric, then this axial unwinding method cannot be used in the weaving process.

[0007] Preferably, the tension sensor control assembly also includes a mounting bracket installed on the outside of the porcelain ring bracket, a first weft yarn tensioner and a second weft yarn tensioner arranged at both ends of the outside of the mounting bracket, a tension sensor fixed to one side of the outside of the mounting bracket, a third guide wheel installed on the outside of the tension sensor, and a first guide wheel and a second guide wheel respectively arranged on both sides of the outside of the third guide wheel.

[0010] Preferably, a ceramic ring is installed on the outside of the ceramic ring bracket, and the outside of the weft yarn passes through the inside of the ceramic ring.
[0011] Preferably, the weft yarn passes through the inside of the first weft yarn tensioner and the second weft yarn tensioner and is connected to the weft insertion system of the loom.
[0012] Preferably, the tapered sleeve is connected to the bobbin core shaft via a flat key and can rotate synchronously therewith.
[0013] Preferably, the swing arm is fixedly connected to the outside of the transmission shaft, and the plum blossom coupling drives the swing arm to swing left and right through the transmission shaft.
[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0015] The utility model allows one end of the weft yarn to be unwound from the weft yarn bobbin along the bobbin radial direction, and the weft yarn passes through a porcelain ring arranged on the outside of a porcelain ring bracket near the position of a weft yarn bobbin transmission component and is connected to the outside of a first yarn guide wheel, a second yarn guide wheel, a third yarn guide wheel, and a fourth yarn guide wheel. When the weft yarn passes through a first weft yarn tensioner and goes along the second guide wheel, the third guide wheel, the outside of the first guide wheel, and the inside of the second weft yarn tensioner, the weft yarn enters a weft insertion system of a loom, and a servo motor is started to drive the flat key and the bobbin core shaft to rotate, and the bobbin core shaft is connected to the inner wall of the flat key, so that the bobbin core shaft drives the cone sleeve to rotate, and at the same time drives the weft yarn bobbin to rotate, and the torque motor is started to drive the plum blossom coupling to rotate, and the plum blossom coupling drives the transmission shaft, and at the same time the transmission shaft drives the swing rod, so that the transmission shaft and the swing rod are connected. The two guide wheels swing synchronously together. During the whole weft insertion process, the length of the weft yarn unwound from the weft yarn bobbin cannot be completely consistent with the length of the weft yarn required for weft insertion on the loom. Therefore, when the length of the unwound weft yarn is less than that required for weft insertion, the weft yarn tension becomes larger, and the weft yarn pulls the swing rod to swing to the right; when the length of the unwound weft yarn is greater than that required for weft insertion, the weft yarn tension becomes smaller, and the swing rod is subjected to the torque applied by the torque motor, overcoming the weft yarn tension and swinging to the left. When the weft yarn tension wound on the third guide wheel changes, the force acting on the tension sensor also changes accordingly. The tension sensor outputs an electrical signal with corresponding changes, and the control system uses this to control the speed of the servo motor, thereby controlling the length of the unwound weft yarn. In this process, additional twisting on the flat yarn is avoided, while improving product quality.
[0016] The utility model has a section of weft yarn between the first yarn guide wheel, the second yarn guide wheel, the third yarn guide wheel and the fourth yarn guide wheel. The length of this section of weft yarn changes with the swing of the swing rod. When the swing rod swings to the left, the length of this section of weft yarn becomes longer; when the swing rod swings to the right, the length of this section of weft yarn becomes smaller. This is equivalent to providing a buffer for the weft yarn amount required for weft insertion of the loom. The length of the unwound weft yarn is strictly consistent with the weft insertion requirement of the loom without the need for the servo motor to rotate. The tension sensor detects the change of the weft yarn tension, thereby controlling the rotation speed of the servo motor and then controlling the unwinding length of the weft yarn, which can ensure the normal weft insertion of the loom, improve the efficiency of weaving production, and reduce the production cost. The flat yarn radial unwinding device based on tension sensor control is more suitable for the weaving production of flat yarns with low tensile strength. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The tension sensor control assembly 5 also includes a mounting bracket 502 mounted on the outside of the porcelain ring bracket 10, a first weft tensioner 503 and a second weft tensioner 504 arranged at both ends of the outside of the mounting bracket 502, a tension sensor 501 fixed to one side of the outside of the mounting bracket 502, a third guide wheel 506 mounted on the outside of the tension sensor 501, and a first guide wheel 505 and a second guide wheel 507 respectively arranged on both sides of the outside of the third guide wheel 506.
[0031] The above scheme is adopted: when one end of the weft yarn 3 is unwound from the weft yarn bobbin 101 along the bobbin radial direction, the weft yarn 3 is passed through the porcelain ring arranged on the outside of the porcelain ring bracket 10 near the position of the weft yarn bobbin transmission component 1 and connected to the outside of the first guide wheel 6, the second guide wheel 7, the third guide wheel 8, and the fourth guide wheel 9, so that the weft yarn 3 passes through the porcelain ring installed on the outside of another porcelain ring bracket 10, and when the weft yarn 3 passes through the first weft yarn tensioner 503 and along the second guide wheel 507, the third guide wheel 506, the outside of the first guide wheel 505 and the inside of the second weft yarn tensioner 504, the weft yarn 3 enters the weft insertion system of the loom, and the servo motor is started. 103 drives the flat key 105 and the bobbin core shaft 110 to rotate, and the bobbin core shaft 110 is connected to the inner wall of the flat key 105, so that the bobbin core shaft 110 drives the conical sleeve 106 to rotate, and at the same time drives the weft bobbin 101 to rotate, and the starting torque motor 202 drives the plum blossom coupling 204 to rotate, and the plum blossom coupling 204 drives the transmission shaft 205, and at the same time the transmission shaft 205 drives the swing rod 201, so that the transmission shaft 205 and the swing rod 201 swing synchronously together. During the whole weft insertion process, the length of the weft yarn 3 unwound from the weft bobbin 101 cannot be completely consistent with the length of the weft yarn 3 required for the weft insertion of the loom. Therefore, when the unwound weft yarn 3 is long When the length of the unwound weft yarn 3 is less than that required for weft insertion, the tension of the weft yarn 3 becomes larger, and the weft yarn 3 pulls the swing rod to swing to the right; when the length of the unwound weft yarn 3 is greater than that required for weft insertion, the tension of the weft yarn 3 becomes smaller, and the swing rod 201 is subjected to the torque applied by the torque motor 202, overcomes the tension of the weft yarn 3 and swings to the left. When the tension of the weft yarn 3 wound on the third guide wheel 506 changes, the force acting on the tension sensor 501 also changes accordingly, and the tension sensor 501 outputs an electrical signal voltage that changes accordingly. The control system controls the speed of the servo motor 103 based on this, and then controls the unwinding length of the weft yarn 3. The weft yarn 3 is moved between the first guide wheel 6, the second guide wheel 7, and the third guide wheel 8. There is a section between the yarn wheel 8 and the fourth yarn guide wheel 9. The length of this section of weft yarn 3 changes with the swing of the rocker arm 201. When the rocker arm 201 swings to the left, the length of this section of weft yarn 3 becomes longer; when the rocker arm 201 swings to the right toward the side of the weft yarn bobbin, the length of this section of weft yarn 3 becomes smaller, which is equivalent to providing a buffer for the amount of weft yarn 3 required for weft insertion of the loom. The length of the unwound weft yarn 3 is strictly consistent with that required for weft insertion of the loom without the need for the servo motor 103 to rotate. The tension sensor 501 detects the change in the tension of the weft yarn 3, thereby controlling the rotation speed of the servo motor 103 and then controlling the unwinding length of the weft yarn 3, thereby ensuring normal weft insertion of the loom.
[0032] like Figure 7As shown, after the weft yarn 3 comes out from the fourth guide wheel 9 and the porcelain ring, it enters the first weft tensioner 503, winds around the second guide wheel 507, the third guide wheel 506, the first guide wheel 505 and the tension sensor 501 in the three-wheel tension sensor assembly, and then enters the weft insertion system of the loom. In the three-wheel tension sensor, the first guide wheel 505 and the second guide wheel 507 are fixedly installed and can rotate; the third guide wheel 506 is installed on the tension sensor 501, and the force acting on the third guide wheel 506 will be directly transmitted to the tension sensor 501, and the tension sensor 501 will output an electrical signal voltage of corresponding size according to the size of the force received.
[0033] like Figure 1 , Figure 2 As shown, when the weft insertion of the loom starts, the servo motor 103 drives the weft yarn bobbin 101 to rotate and unwind the weft yarn 3 for the weft insertion of the loom. Since the length of the weft yarn 3 unwound by the weft yarn bobbin 101 cannot be completely consistent with the length of the weft yarn 3 required for the weft insertion of the loom during the entire weft insertion process, when the length of the unwound weft yarn 3 is less than the length required for the weft insertion, the tension of the weft yarn 3 increases, and the weft yarn 3 pulls the swing rod 201 to swing to the right; when the length of the unwound weft yarn 3 is greater than the length required for the weft insertion, the tension of the weft yarn 3 decreases, and the swing rod 201 is subjected to the torque applied by the torque motor 202, overcoming the tension of the weft yarn 3 and swinging to the left; when the tension of the weft yarn 3 wound around the third guide wheel 506 changes, the force acting on the tension sensor 501 also changes accordingly, and the tension sensor 501 outputs a correspondingly changing electrical signal voltage, and the control system controls the rotation speed of the servo motor 103 thereby controlling the length of the unwound weft yarn 3.
[0034] like Figure 1 As shown, there is a section of weft yarn 3 between the first yarn guide wheel 6, the second yarn guide wheel 7, the third yarn guide wheel 8, and the fourth yarn guide wheel 9. The length of this section of weft yarn 3 changes with the swing of the swing rod 201. When the swing rod 201 swings to the left, the length of this section of weft yarn 3 becomes longer; when the swing rod 201 swings to the right toward the side of the weft yarn bobbin, the length of this section of weft yarn 3 becomes smaller, which is equivalent to providing a buffer for the amount of weft yarn 3 required for weft insertion of the loom. The length of the unwound weft yarn 3 is strictly consistent with the length required for weft insertion of the loom without the need for the servo motor 103 to rotate. The tension sensor 501 detects the change in the tension of the weft yarn 3, thereby controlling the speed of the servo motor 103 and then controlling the unwinding length of the weft yarn 3, which can ensure the normal weft insertion of the loom. The radial unwinding device of the weft yarn 3 directly detects the tension of the weft yarn 3, controls the speed of the servo motor 103, and controls the unwinding length of the weft yarn 3, thereby meeting the weft insertion requirements of the loom, and is suitable for weaving flat weft yarn 3 with relatively low strength.
[0035] The working principle and use process of this utility model:
[0036] First, when one end of the weft yarn 3 is unwound from the weft yarn bobbin 101 along the bobbin radial direction, the weft yarn 3 is passed through the porcelain ring arranged on the outside of the porcelain ring bracket 10 near the position of the weft yarn bobbin transmission component 1 and connected to the outside of the first guide wheel 6, the second guide wheel 7, the third guide wheel 8, and the fourth guide wheel 9, so that the weft yarn 3 passes through the porcelain ring installed on the outside of another porcelain ring bracket 10, and when the weft yarn 3 passes through the first weft yarn tensioner 503 and along the second guide wheel 507, the third guide wheel 506, the outside of the first guide wheel 505 and the second weft yarn tensioner 504, the weft yarn 3 enters the weft insertion system of the loom, and the servo motor 103 is started to drive The flat key 105 and the bobbin core shaft 110 rotate, and the bobbin core shaft 110 is connected to the inner wall of the flat key 105, so that the bobbin core shaft 110 drives the conical sleeve 106 to rotate, and at the same time drives the weft bobbin 101 to rotate, and the starting torque motor 202 drives the plum blossom coupling 204 to rotate, and the plum blossom coupling 204 drives the transmission shaft 205, and at the same time the transmission shaft 205 drives the swing rod 201, so that the transmission shaft 205 and the swing rod 201 swing synchronously together. During the whole weft insertion process, the length of the weft yarn 3 unwound from the weft bobbin 101 cannot be completely consistent with the length of the weft yarn 3 required for the weft insertion of the loom. Therefore, when the length of the unwound weft yarn 3 is insufficient, the length of the unwound weft yarn 3 is insufficient. When weft insertion is required, the tension of weft yarn 3 increases, and weft yarn 3 pulls the swing rod to swing to the right; when the length of unwound weft yarn 3 is greater than that required for weft insertion, the tension of weft yarn 3 will decrease, and the swing rod 201, under the torque applied by torque motor 202, overcomes the tension of weft yarn 3 and swings to the left. When the tension of weft yarn 3 wound on the third guide wheel 506 changes, the force acting on the tension sensor 501 also changes accordingly, and the tension sensor 501 outputs an electrical signal voltage that changes accordingly. The control system uses this to control the speed of servo motor 103, and then controls the length of unwinding of weft yarn 3; weft yarn 3 is moved between the first guide wheel 6, the second guide wheel 7, and the third guide wheel 8. There is a section of length between the fourth yarn guide wheel 9, and the length of this section of weft yarn 3 changes with the swing of the rocker arm 201. When the rocker arm 201 swings to the left, the length of this section of weft yarn 3 becomes longer; when the rocker arm 201 swings to the right toward the side of the weft yarn bobbin, the length of this section of weft yarn 3 becomes smaller, which is equivalent to providing a buffer for the amount of weft yarn 3 required for weft insertion of the loom. The length of the unwound weft yarn 3 is strictly consistent with the length required for weft insertion of the loom without the need for the servo motor 103 to rotate. The tension sensor 501 detects the change in the tension of the weft yarn 3, thereby controlling the rotation speed of the servo motor 103 and then controlling the unwinding length of the weft yarn 3, thereby ensuring normal weft insertion of the loom.
