Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is intended to correct a cloth, such as a knitted or woven cloth, which is relatively thick and does not need to be spread, when the cloth is deviated from a regular path so as to correct the path. Of equipment.

[0002]

2. Description of the Related Art Conventionally, what is called a pile drawing machine is known as a two-sided warp The technology to manufacture warp knitted fabric with piles on both sides by pulling out after center cutting
It is known from No. 14391.

In this pile drawing machine, the above-mentioned two-sided warp knitted fabric is arranged at the rear part of the machine for being introduced into the pile drawing apparatus and is continuously conveyed into the machine. Due to the difference in the pile yarn braided state at each position, the material to be conveyed deviates from the regular path and meanders to the left and right. Therefore, in order to correct this meandering, as shown in FIG. The entire support frame 31 supporting the roll 30 can be tilted rightward or leftward with respect to the arrow 14 in the traveling direction of the fabric 13 by the rotation control of a servomotor (not shown) about the support shaft 32. Set up. On the other hand, a sensor for detecting the displacement of the traveling position is provided in the traveling portion of the cloth 13, and the servo motor is rotated by the signal from this sensor, so that the cloth 13 is offset to the right in the drawing as shown in FIG. 5, for example. If the roll 30 is tilted to the right, it is corrected to the left side, and when it returns to the normal position, the servo motor receives the signal from the sensor and rolls 3
0 in the direction of arrow 33 to roll 3 in the direction of travel 14
The neutral position is achieved by returning the 0 axis direction to the right angle direction.
Further, when the cloth 13 is offset to the left, it is corrected by inclining the roll 30 to the left.

[0004]

However, in the above correction device, the weight of the entire portion including the roll is increased and the driving torque is increased, so that the motion of the entire roll is apt to be unstable and the traveling speed is suppressed to a low speed. To be Furthermore, a large installation space is required for the device due to the necessity of tilting the rolls to the left and right. Further, when a large tension is applied to the cloth, a load is applied to the drive for moving the position of the roll, which may hinder the smooth operation.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned drawbacks and provides a fabric running correction device which is relatively compact and which can carry out the correction quickly and effectively.

[0006]

SUMMARY OF THE INVENTION According to the present invention, at least one temple ring, which is non-rotatably fitted to a temple control shaft through a bearing ring which is non-rotatably fitted in a tilted manner, is used for running cloth. Are arranged at both ears of the temple control shaft, and a rotating means such as a motor is connected to at least one side of the temple control shaft, and a guide roller is provided in parallel with the temple control shaft. A signal from a sensing means such as a sensor is sent to the rotating means, and the rotating action of the rotating means on the temple control shaft causes the temple ring to act on the cloth in the left or right direction with respect to the cloth traveling direction. It is configured so that the running deviation of the cloth is corrected by inclining it or by making the temple ring neutral so that it does not act on the cloth.

[0007]

[Function] When a plurality of temple rings arranged on both ears of the cloth are shifted to the right side of the cloth, the temple shaft is rotated by a rotating means such as a motor to be tilted to the left to move the cloth to the left. Will be fixed. Further, when the cloth is shifted to the left side, the cloth is corrected to move to the right by rotating the temple shaft in the opposite direction by a rotating means such as a motor to make the cloth inclined to the right. Then, in a normal running state, the temple ring is kept in a neutral state and has no effect on the cloth, so that the cloth is continuously conveyed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the cloth running correction device of the present invention will be described with reference to the drawings. 1 and 2 are plan views showing the operating state of the cloth traveling correction position. Reference numerals 1 and 2 are guide rollers, and 3 is a temple ring fitted on the temple control shaft 4, and a large number of needles 5 are provided on the peripheral surface so as to project. Reference numerals 6 and 7 denote holding frames, which rotatably and rotatably support the guide rollers 1 and 2 and the temple control shaft. Reference numeral 8 is a servomotor as a rotating means, and the bearing ring 9 of the motor 8 and the temple shaft 4 are connected by a coupling 10.
Reference numerals 11 and 12 denote sensors that detect a state in which the fabric 13 deviates to the right or left in the traveling direction 14 and emit a signal.

FIG. 3 is a sectional view showing a related structure of the temple ring 3 and the temple control shaft 4. The temple ring 3 on which the needle 5 is planted on the peripheral surface is the key 15 on the temple control shaft 4.
Is rotatably fitted to the bearing ring 16 which is fitted so as not to rotate. The bearing ring 16 is configured to be tilted by about 70 ° with respect to the axial center direction of the temple control shaft 4, and is fitted to the end portion so that one end contacts the nut 18 and the other end has an inclined surface. Several temple rings 3 are inserted through a retaining ring 17 having 17a, and are sandwiched between the inclined surface 19a of a roller 19 which is fitted in the central portion.

Although only one end of the temple control shaft 4 is shown in FIG. 3, the structure of the temple ring 3 and the control shaft 4 is the same on the other end side as well, and a description thereof will be omitted.

The number and inclination angle of the temple rings 3 are
The conveying speed and the tension of the cloth are taken into consideration and the present invention is not limited to those in the examples, and may be set in an appropriate range and length.

Next, the operating state of this apparatus will be described.
In FIG. 1, when the cloth 13 being conveyed is displaced in the direction of the arrow 20 (on the left side on the paper surface), the sensor 11 detects the deviation,
A drive signal is sent to the servomotor 8 via a known control position (not shown) to rotate the rotary shaft so that the temple ring 3 is tilted to the right with respect to the axial direction of the temple control shaft 4 as shown. To be set. The positioning is performed by an encoder built in the motor 8. Then, by stopping the rotation of the control shaft 4 at that position, the fabric 13 gradually moves in the direction of the arrow 21 along the inclined direction of the rotated temple ring 3 as shown in FIG. Then, a signal is sent again to the servo motor 8 to move the temple ring 3 to a neutral position where it does not tilt to the left and right, so that the cloth 13 can proceed in the normal running direction 14.

Further, if the cloth 13 is offset in the direction of the arrow 21 as shown in FIG. 2, the sensor 12 senses the offset and rotates the rotary shaft 9 in the same manner as described above, thereby controlling the temple. The shaft 4 is also rotated so that the temple ring 3 is set to be inclined to the left with respect to the axial direction of the temple control shaft 4. At this position, the fabric 13 gradually moves in the direction of the arrow 20 along the inclination direction of the temple ring 3 and when it comes to the normal position, a signal is sent to the servo motor 8 again, and the temple ring 3 is moved in the same manner as described above. By moving 3 to a neutral position where it does not tilt to the left or right, the fabric 13 can be advanced in the normal running direction 14.

[0014]

According to the cloth traveling correction position of the present invention,
Since the cloth transport roll itself is installed at a fixed position and the inclination of only the temple rings provided at both ends of the cloth is controlled by the rotation control of the temple control shaft, the modification of the cloth can be performed stably, quickly and safely. In addition, there is an effect that the installation space of the device can be reduced.
