Stops working. In the state where the cutter lever 73 is pivotally arranged at the cutting position, the sharp end of the cloth insertion bar 97 is pressed against the peripheral surface of the empty roll 8B via the woven cloth W by the spring action of the pressing springs 97a and 97b.

When the empty roll 8B is mounted at the cloth winding position S ₁ , it is rotated in the cloth winding direction by the empty roll winding motor 25 and the proximity switch 93 causes the proximity switch 93 to move.
A pulse signal corresponding to the rotation speed of B is output. In response to this pulse signal, the control computer C ₁ operates the full roll winding motor 43 in the normal direction.

As shown in FIG. 19, a cloth gripping groove 8e is formed on the peripheral surface of the cross roll 8 along the axial direction, and the cloth gripping groove 8e is formed along with the rotation of the empty roll 8B.
7, the cloth insertion bar 97 is fitted into the cloth grip groove 8e. This fitting action prevents the empty roll 8B from rotating and the woven fabric W is inserted into the fabric gripping groove 8e. Due to this rotation stop, the torque motor type empty roll winding motor 25 is not driven to rotate, and the rotational drive force on the loom drive motor side is absorbed by the torque limiter 86 between the surface roller 4 and the drive gear 19.

The proximity switch 94 outputs a pulse signal corresponding to the rotation speed of the full roll 8A caused by the forward rotation of the full roll winding motor 43. When the pulse frequency f ₁ becomes equal to or less than the set number F ₁ , the cutter drive motor 75 operates in the normal direction, and the disc cutter 80 starts traveling from the right side frame 1 side to the left side frame 2 side. At the same time, the electromagnetic valve V ₁ is excited and the winding nozzle 81 starts jetting, as shown in FIG.

The set number F ₁ is the empty roll 8B and the full roll 8A.
Is a standard for grasping the tension of the woven cloth W between the woven cloth W and this value, and this value is the rotation of the torque motor type full roll winding motor 43 when the cloth tension suitable for cutting the woven cloth W is reached. It is the pulse frequency corresponding to the number. As the tension of the woven cloth W increases, the rotation speed of the full roll winding motor 43 decreases. Therefore, when the pulse frequency f ₁ becomes equal to or less than the set number F ₁ , the tension of the woven fabric W becomes a tension suitable for cutting by the disc cutter 80, and the disc cutter 80
Smoothly cuts the woven cloth W in an appropriate tension state.

When the drive pulse number m ⁺ for the stepping motor type cutter drive motor 75 reaches the set number M, the operation of the cutter drive motor 75 is stopped. The set number M is set so that the disk cutter 80 moves a distance that allows the woven cloth W to be completely cut.

After the normal rotation operation of the full roll take-up motor 43 is started, when the number n of detection pulses output from the proximity switch 94 reaches the set number N, the operations of the full roll take-up motor 43 and the proximity switch 94 are stopped. The woven fabric cutting end W ₁ of the full roll 8A side of the woven fabric W cut by the disc cutter 80 hangs down from the peripheral surface of the full roll 8A, but the full roll 8A is kept until the detected pulse number n reaches the set number N. By continuing to turn, the woven fabric cut end W ₁ is wound around the peripheral surface of the full roll 8A, and the hanging state of the woven fabric cut end W ₁ disappears. In this state, the full roll 8A waits for the cross roll carrier 98 to arrive.

After the disc cutter 80 cuts the woven fabric W forward,
The cutter drive motor 75 operates in the reverse direction, and the disk cutter 8
0 moves back from the left side frame 2 side toward the right side frame 1 side. When the drive pulse number m ⁻ for the cutter drive motor 75 reaches the set number M, the operation of the cutter drive motor 75 is stopped and the disc cutter 80 returns to the standby position.

As shown in FIGS. 20 and 21, the empty roll 8
The cut end W ₂ of the woven cloth on the B side is wound around the peripheral surface of the empty roll 8B by the jet of the winding nozzle 81. Peripheral surface of the large diameter shaft 8b of the cross roll is formed in a rough surface, fabric cutting edge W ₂ is attached to the rough circumferential surface of the large-diameter shaft 8b.

After the cut end W _{2 of the} woven fabric is wound around the empty roll 8B, the electromagnetic valve V ₂ is excited and the drive rod 18a of the air cylinder 18 projects. As shown in FIG. 22, the meshing state between the claw member 14 and the ratchet wheel 13 is released by the extension operation of the air cylinder 18. In this disengaged state, the leaf spring 17 moves the ratchet wheel 13
It is strongly pressed against the tip of the claw, and the pressing action of the leaf spring 17 holds the cross guide bar 7 at the position before the disengagement.

Rotate down against the use. The spring action of the leaf spring 17 is black.
The sack bar 7 is prevented from falling rapidly, and the woven cloth is cut.
Edge W₂Is given an appropriate tension.

The proximity switch 93 outputs a pulse signal corresponding to the rotation speed of the empty roll 8B as the empty roll 8B is rotated by the operation of the empty roll winding motor 25. When the frequency f ₂ of this pulse signal becomes equal to or less than the set number F ₂ , the operation of the empty roll winding motor 25 is stopped. When the pulse frequency f ₂ reaches the set number F ₂ , it means that the cross guide bar 7 is in contact with the peripheral surface of the empty roll 8B, and the tension of winding the cloth thereafter is up to the tension set by the torque limiter 86. To rise. Due to such increase in tension, the rotating torque of the empty roll 8B increases, the empty roll winding motor 25 stops rotating, and the empty roll 8B is rotated by the rotational driving force on the loom drive motor side.

With the above, the exchange of the full roll 8A and the empty roll 8B is substantially completed. After the operation of the empty roll winding motor 25 is stopped, the electromagnetic valves V _{1 and} V ₂ are demagnetized, the injection of the winding nozzle 81 is stopped, and the air cylinder 18 is stopped.
The drive rod 18a of is operated. Due to the shortening operation of the air cylinder 18, the pawl member 14 again meshes with the ratchet wheel 13 by the spring action of the leaf spring 17.

After demagnetizing the electromagnetic valves V _{1 and} V ₂ , the control computer C ₁ outputs a guided vehicle calling signal to the loom control computer C ₀ and operates the area sensors 44 and 45. Temporary position S due to the operation of area sensors 44 and 45
The existence of full roll 8A on ₂ is grasped. Motor 38 while the full roll 8A on the temporary location position S ₂ is present is not actuated and does not fully roll bracket 30, 31 is pivotally raised from the transfer position to the storage position.

As shown in FIG. 25, the cross roll carrier 9
8 is called in response to the vehicle call signal from the loom control computer C _0, and arrives at the cross roll transfer work position in front of the loom. The cross roll transfer vehicle 98 stopped at the cross roll transfer operation position transfers the full roll 8A on the temporary placement position S ₂ to the transfer vehicle by the cooperation of the transfer arm 98a and the transfer hand 98b. As shown in FIG. 26, the transfer hand 98b engages with the annular groove 8c of the full roll 8A. In other words, the annular groove 8c is a transfer groove, and the transfer groove 8c is used for discharge rolling of the full roll 8A from the woven fabric winding position S ₁ to the temporary placement position S ₂ .

As shown in FIG. 27, when the full roll 8A is transferred from the temporary placement position S ₂ to the cross roll carrier 98 side,
The control computer C ₁ operates the motor 38 in the reverse direction based on the full roll absence detection signals from the area sensors 44 and 45. By this reverse operation, the full roll brackets 30, 3
1 rotates up from the transfer position to the storage position. When the full roll brackets 30 and 31 are returned to the storage position, the limit switch Ls ₁ is turned on, the operation of the motor 38 is stopped, and the area sensors 44 and 45 are also stopped.

According to this embodiment, in the loom of the type in which the cloth roll 8 at the cloth winding position is directly connected to the drive mechanism of the main body of the loom for winding, the small diameter shaft 8a of the empty roll 8B is supported by the supporting seat. 9 and 10 bearing recesses 9a and 10a

When the empty roll 8B is mounted at the cloth winding position S ₁ , it is rotated in the cloth winding direction by the empty roll winding motor 25, and the proximity switch 93 causes the empty switch 8B to move.
A pulse signal corresponding to the rotation speed of B is output. In response to this pulse signal, the control computer C ₁ operates the full roll winding motor 43 in the normal direction.

As shown in FIG. 11, a cloth gripping groove 8e is formed on the peripheral surface of the large diameter shaft 8b of the cross roll along the axial direction, and the cloth gripping groove 8e is formed as the blank roll 8B rotates. Upon encountering the insertion bar 97, the cloth insertion bar 97 is fitted into the cloth grip groove 8e as shown in FIG. This fitting action prevents the empty roll 8B from rotating and the woven fabric W is inserted into the fabric gripping groove 8e. Due to this rotation stop, the torque motor type empty roll winding motor 25 is not driven to rotate, and the rotational drive force on the loom drive motor side is absorbed by the torque limiter 86 between the surface roller 4 and the drive gear 19.

After the normal rotation operation of the full roll winding motor 43 is started, when the number of detection pulses output from the proximity switch 94 reaches the set number, the operations of the full roll winding motor 43 and the proximity switch 94 are stopped, and the full roll 8A Will wait for the cross-roll carrier to arrive.

A pipe-shaped winding nozzle 81 is arranged on the support bar 74 over the entire length of the support bar 74, and the jet directions of a plurality of injection ports of the winding nozzle 81 are moved by the disc cutter 80. It is set to point to the opposite side of the area. The disk cutter 80 reciprocates on the support bar 74 after the full-roll winding motor 43 operates in the normal direction,
The woven cloth W between the full roll 8A and the empty roll 8B is cut. Winding nozzle 81 with traveling of disk cutter 80
The electromagnetic valve V ₂ for use is excited, and the woven cloth cut end W ₂ on the side of the empty roll 8B is wound around the peripheral surface of the empty roll 8B by the injection of the winding nozzle 81. After the woven cloth cut end W ₂ is wound around the empty roll 8B, the meshing state between the pawl member 14 and the ratchet wheel 13 is released by the expansion operation of the air cylinder 18 by the excitation of the electromagnetic valve V ₁ for the air cylinder 18. However, the cross guide bar 7 has a leaf spring 17
Is held at the position before the disengagement.

Under this condition, the cutter levers 72, 7
3 turns down. When the cutter levers 72 and 73 are rotated and lowered, the cloth insertion bar 97 is separated from the cloth gripping groove 8e, and the empty roll 8B on the cloth winding position S ₁ is rotated in the cloth winding direction by the operation of the empty roll winding motor 25. To do. As shown in FIG. 9, the woven cloth cutting end W ₂ is wound around the empty roll 8B by the rotation of the empty roll 8B, and the cross guide bar 7 turns downward against the spring action of the leaf spring 17.

The proximity switch 93 outputs a pulse signal corresponding to the rotation speed of the empty roll 8B as the empty roll 8B is rotated by the operation of the empty roll winding motor 25. When the frequency of this pulse signal becomes equal to or less than the set number, the operation of the empty roll winding motor 25 is stopped. When the pulse frequency reaches the set number, the cross guide bar 7 is empty roll 8B.
The woven fabric winding tension thereafter increases to about the tension set by the torque limiter 86. Due to such increase in tension, the rotating torque of the empty roll 8B increases, the empty roll winding motor 25 stops rotating, and the empty roll 8B is rotated by the rotational driving force on the loom drive motor side.

With the above, the exchange of the full roll 8A and the empty roll 8B is substantially completed. When the full roll 8A is transferred from the temporary placement position S ₂ to the cross roll transfer vehicle side by the arrival and transfer operation of the cross roll transfer vehicle, the motor 38 is reversely operated and the full roll brackets 30 and 31 are moved from the transfer position. Rotate up to the storage position. When the full roll brackets 30 and 31 are returned to the storage positions, the operation of the motor 38 is stopped and the area sensors 44 and 45 are also stopped.
