They are spaced apart in the width direction.

Here, a locking mechanism 3 is connected to the dispensing mechanism 6, and the dispensing mechanism 6 and the locking mechanism 3 are driven by an air cylinder 100 as the same actuator assembled on the side frame 10. ing. Specifically, the other end of the rod member 30 of the locking mechanism 3 extending downward is connected to the front part of the base plate 60 of the dispensing mechanism 6 by a pin 101 constituting an interlocking part. The vertical middle part of the rod member 30 is a guide plate h10 attached near the lower part of the fully cloth-wound roll stocker 2 of the side frame 10.
It is movably inserted into the guide hole 103 of No. 2. An end of an operating rod 104 of the air cylinder 100 is connected to the pin 101 . A cylinder tube 105 of the air cylinder 100 is connected to the side frame 10 with a pin 106.

According to the above embodiment structure, as shown in FIGS. 1A and 2, the air cylinder 100 is contracted, the dispensing part 61 of the dispensing mechanism 6 is stopped at the backward limit position, and the locking mechanism 3 is When the member 30 enters the fully cloth-wrapped roll stocker 2 and the fully cloth-wound roll B is held in the fully cloth-wound roll stocker 2, the fabric C is first positioned in the winding drive mechanism 1 as the weaving operation progresses. The weaving cloth is then wound onto the cloth-wound roll A which is being driven to rotate, and when the cloth-wrapped roll A reaches a predetermined amount of wrapping, the air cylinder 100 is driven to extend while the weaving operation continues. Then, as shown in FIG. 3, as the actuating rod 104 extends, the dispensing portion 61 of the dispensing mechanism 6 moves forward about the support shaft 11a to move the cloth-wound roll A from above the front and rear rollers 11 and 12 to the front. The cloth-wrapped roll A is pushed toward the full cloth-wrapped roll stocker 5 side than the top of the roller 11, and the cloth-wound roll A moves forward by its own weight from the dashed line as shown by the imaginary line beyond the top of the front roller 12. The cloth is fully wound and placed on the roll stocker 5. At this time, the woven fabric C continues from the vent bar 18 to the cloth-wound roll A via the front roller 11 and stocker plate 51. Also, due to the forward movement of the dispensing portion 61 of the dispensing mechanism 6, the cam 4
1 moves below the receiving part 43 of the tank arm 40, and the rod member 30 of the locking mechanism 3 exits the fully cloth-wound roll stocker 2 while being guided by the guide hole 103, tracing a trajectory indicated by a dash-dotted line. The fully cloth-wrapped roll B slides down the lower wall 21 and is placed on the receiving part 43, and the receiving part 43 moves slightly downward around the pin 42 due to the weight of the fully cloth-wound roll B and is supported in contact with the cam 41. Ru.

Next, the air cylinder 100 is driven to contract from the state shown in FIG. Then, as shown in FIG.
As the size decreases, the dispensing part 61 of the dispensing mechanism 6 moves backward around the support shaft 11a, and the dispensing part 61
When the upper end of the damper arm 40 moves to the rear of the fully cloth-wound roll B on the receiving portion 43, the tip of the damper arm 40 moves downward around the bin 42 along the cam 41 due to the weight of the fully cloth-wound roll B. The fully cloth-wrapped roll B is at the receiving part 43
While correcting the position so that it is parallel to the axis of the front and rear rollers 11 and 12 (the drive axis of the winding drive unit 1), it is released so as to be guided by the front and rear rollers 11 and 12, and is moved back and forth as shown by the dashed line. It is supplied and placed on rollers 11 and 12. At this time, the fully cloth-wound roll B may come into contact with the dispensing section 61 from the receiving section 43 and arrive at the front and rear rollers 11 and 12. Further, as the dispensing mechanism 6 returns, the rod member 30 of the locking mechanism 3 enters into the fully cloth-wound roll stocker 2.

Then, as shown in FIG. 4, a part of the woven fabric C is sandwiched between the fully wrapped cloth roll B and the front roller 11, and the cloth wrapped roll is placed on the fully wrapped cloth rolled roll stocker 5 from the front roller 11. A, by moving the cutter mechanism 7 from one side frame 10 toward the other side frame 10, the cutter mechanism 7 is placed on the front and rear rollers 11 and 12 as shown by the solid line in FIG. The woven fabric C is cut between the fully wound cloth roll B and the cloth wound roll A placed on the fully wound cloth roll stocker 5.

Thereafter, as shown in FIG. 5, the winding mechanism 8 wraps the front roller side cut end Ca of the woven fabric C as the winding drive mechanism side cut end on the front and rear rollers 11. The entire fabric is wound onto roll B on I2. In other words, first blow up nozzle 8
After air is injected in the direction of arrow X from 0 to superpose the front roller side cut end portion Ca on the entire cloth-wound roll B, the air injection from the blow-up nozzle 80 is stopped. Then, as the front roller 11 and the fully cloth-wrapped roll B are driven to rotate, the front roller side cut end Ca passes between the rear roller 12 and the fully cloth-wound roll B while superimposing on the fully cloth-wound roll B. protrude downward. At this time, the separation nozzle 81 and the blowing nozzle 8
Air from 2 to arrow X! , X, ejects in the direction. Then, the cut end portion Ca of the front roller protruding from between the rear roller 12 and the fully cloth-wound roll B is separated from the rear roller 12 by the air from the separation nozzle 81, and the square vibrator 85 and the fully cloth-wound roll B are separated. The air from the blowing nozzle 82 blows toward the guide plate 83 side through the gap, and then blows against the guide plate 83 to completely wrap the cloth-wound roll B.
and the front roller 11, specifically, between the woven fabric C connected from the vent par 18 to the front roller 11 and the fully cloth-wrapped roll B, and is wound around the fully cloth-wrapped roll B as shown by the 7-dot chain line. It will be done. Upon completion of this winding, air injection from the separation nozzle 81 and the blowing nozzle 82 is stopped. This completes one cycle of cloth winding roll replacement work.

By the way, the cut end Ca on the front roller side is the vent par 18.
When the continuous woven fabric C is blown between the woven fabric C and the fully cloth-wrapped roll B and wound around the fully cloth-wrapped roll B, the rear roller 12 and the fully cloth-wrapped roll B are normally moved in the direction of the arrow shown in FIG. While rotating, the front roller 11 may be forcibly stopped or reversed to more firmly wrap the cut end Ca around the fully cloth-wound roll B.

When this cycle of cloth-wrapped roll replacement work is completed, a cloth-wrapped roll replacement instruction is given, and a carrier loaded with all cloth-wrapped rolls and ready for replacement is called from the factory's carrier store (not shown) and placed at the front of the loom. On the other hand,
The full roll transfer arm assembled on the carrier grasps a predetermined amount of the woven fabric or the wrapped cloth roll A on the fully wrapped cloth roll stower 5, moves and places it on the carrier, and is assembled on the carrier. After the empty transfer arm supplies the fully cloth-wound rolls from the carrier to the fully cloth-wound roll stocker 2, the fully cloth-wound rolls are transported to the carrier store of the factory by movement of the carrier. When the fully cloth-wound roll B is supplied from the carrier to the fully cloth-wound roll stocker 2, the rod member 3° of the locking mechanism 3 enters into the fully cloth-wound roll stocker 2 as the dispensing mechanism 6 moves back. Therefore, this fully cloth-wrapped roll B is held in the fully cloth-wound roll stocker 2 by the locking mechanism 3 in preparation for the next cloth-wound roll replacement.

According to this embodiment, since the fully cloth-wound roll B or the fully cloth-wound roll stocker 2 is dropped and supplied to the winding drive mechanism l in multiple stages via the damper mechanism 4, the empty cloth-wound roll stocker 2 is fed to the winding drive mechanism l. It is possible to prevent the attitude of the empty cloth winding roll B from tilting during the process of moving to the winding drive mechanism 1, and the collision force with the winding drive mechanism 1 can be reduced.

In the above embodiment, the rod member 30 is attached to the base plate 60 as a linking part between the dispensing mechanism 6 and the locking mechanism 3.
As shown in FIG. 6, an arm 302 that swings around a fixed shaft 300 is provided as the locking mechanism 3, and an empty cloth wrapped roll is attached to one end of the arm 302. A stopper pin 600 is formed with a block 301 that locks B, and the other end is formed on the base plate 60.
They may be interlocked by engaging with each other.

Further, although not shown in the drawings, for example, the winding drive unit may be configured as a so-called center drive type in which both ends of the cloth winding roll are rotated by a drive shaft assembled to a side frame.

Effects of the Invention As described above, according to the present invention, it is possible to replace the cloth winding roll on the loom without stopping the weaving operation, and moreover, it is possible to replenish the empty cloth winding roll and to wind the cloth using a carrier. Even when transporting the cloth-wrapped roll, it is only necessary to carry out the transportation until the cloth-wrapped roll located in the winding drive mechanism reaches a predetermined amount of winding, so the operating rate of the loom can be improved. In particular, since the dispensing mechanism and the locking mechanism can be linked by the same actuator, the structure of the device can be simplified and costs can be reduced.
