Abstract

PURPOSE:To enable rapid and sure cutting of a cloth by bringing the cloth connecting to a cloth roll into contact with a rotating blade coaxially rotating with a fluid turbine rotating at a high speed under a pressure of a fed high- pressure fluid. CONSTITUTION:A cloth roll is moved to a stocker by operation of a delivery mechanism of a loom. In the process, a motor (77b) is normally rotated and driven before crossing the topmost part of a front roller 11 to rotate a driving pulley (77c) in the direction of an arrow. Control is performed so that a body 71 may be forwardly moved to the left and a cover 74 may be located on the left outside of a cloth (C). A pressurized fluid is simultaneously fed to an inlet (73m) of a fluid turbine 73 to rotate a rotating blade 72 mounted on the rotating shaft of turbine blades (73a) at a high speed. When the aforementioned cloth roll is moved and placed on the stocker and the above-mentioned cover 74 is located on the outside opposite to the aforementioned position of the cloth (C), the above-mentioned motor (77b) is reversely driven to move the body 71 backward in the right direction to bring the cloth (C) into contact with the rotating blade 72. Thereby, the cloth is successively cut over the whole width thereof.

Description

[Detailed description of the invention] Industrial applications The present invention relates to the installation of a loom for cutting woven fabric.

As a cloth cutting device for a conventional technical loom, for example, Japanese Patent Application Laid-Open No. 612306
There is one shown in Publication No. 0. This has a structure in which, when replacing the fabric roll, the woven fabric is cut by rotating the rotary blade with an electric motor and then moving it in the width direction of the fabric with another electric motor.

Problems to be Solved by the Invention Compared to water/etrooms, air shed rooms are woven fabrics with more spun yarns, and the factory environment has a lot of fluff. If it is used, it may come into contact with the moving electric motor's wires or other equipment and damage it, causing a short circuit that may cause fluff or ignition, which is undesirable from a disaster prevention perspective.

Additionally, when the cloth-wrapped roll is removed from the drive shaft and moved, the tension of the woven fabric connected to the cloth-wrapped roll decreases, and if the loom continues to operate, the tension of the woven fabric decreases even more. It turns out.

If there is no tension on the woven fabric, the woven fabric cannot be cut properly. Therefore, it is necessary to install a device to apply tension to the woven fabric, or to increase the rotation speed of the rotary blade. be.

However, if a pressing member (slide bar) is provided and operated in order to apply tension to the woven fabric, the apparatus becomes bulky.

Further, even if an attempt is made to increase the rotational speed of the rotary blade, the rotational speed of the electric motor or the speed increased by using a gear train will not produce a sufficient rotational speed, and the device will become bulky.

At the same time, if the cutting is done in a dull condition,
After the rotary blade passes, the chips accumulate on the moving path of the rotary blade, causing malfunction.

Means for Solving the Problems A fluid-driven motor constitutes a rotary drive mechanism for a rotary blade that cuts the fabric connected to the fabric roll moved forward from the winding drive section of the loom.

According to the above embodiment structure, as shown in FIGS. 1 and 6,
The air cylinder 32 contracts, the dispensing part 61 of the dispensing mechanism 6 stops at the backward limit position, and the rod member 30 of the locking mechanism 3
enters the fully cloth-wound roll stocker 2, and in a state where the cloth roll B is held in the fully cloth-wound roll stocker 2, first, as the weaving operation progresses, the cloth C is positioned in the winding drive mechanism 1. The cloth is wound around the cloth-wound roll A which is being driven to rotate, and when the cloth-wrapped roll A reaches a predetermined amount, the air cylinder 32 is driven to extend while the weaving operation continues. Then, as shown in Fig. 7, the operating rod 3
6 elongates, the dispensing part 61 of the dispensing mechanism 6 moves forward around the support IFlllla to move the cloth-wrapped roll A from above the front and rear rollers 1112 to the top of the front roller 11 and into the fully-wound cloth-wound roll stocker. Push it to the 5 side,
The cloth-wrapped roll A is moved forward by its own weight from the dashed line to the imaginary line as shown by the imaginary line beyond the outermost part of the front roller 12, and is placed on the fully-wound cloth-wound roll stocker 5. At this time, the woven fabric C is continuous from the front roller 11 to the cloth winding roll A via the front roller 11 and the stoso couplers 1 and 5. Also, due to the forward movement of the dispensing part 61 of the dispensing mechanism 6, the cam 41

At this time, the fully cloth-wound roll B may come into contact with the dispensing part 61 from the stopper part 43 and arrive at the front and rear rollers 11 and 12.

Further, with the return movement of the dispensing mechanism 6, the locking mechanism 3
The rod member 30 enters into the fully cloth-wound roll stocker 2.

As shown in FIG. 8, a cloth-wrapped roll that is sandwiched between part or all of the woven cloth C and the front roller 11 and placed on the fully-wound cloth-wrapped roll stocker 5 from the front roller 11 A, by moving the cloth cutting device 7 from one side frame 10 toward the other side frame 10, the cloth cutting device 7 is placed on the front and rear rollers 11, 12 as shown by the solid line in FIG. Full cloth-wrapped roll n and 7 +: l'j cloth-conquering rolls 1 nonono 5 to fight i
The woven fabric C is cut between the filter cloth winding roll 8 and the filter cloth wrapping roll 8.

When cutting the fabric in this embodiment, first, by the forward movement of the above-mentioned dispensing mechanism 6, before the fabric roll A crosses the most part of the front roller 1, the motor 77b is driven to rotate and pressure is applied. Pressurized fluid (eg, air or water) is supplied from a fluid supply source to the inlet 73m of the fluid turbine 73. That is, the forward rotation of the motor 77b rotates the drive boot lift 7c in the direction of the arrow shown in FIG. The motor 77b is driven and controlled so that the cover 74 is positioned from the outer position on the right side of the fabric C to the inner side of the fabric C, and the cover 74 is positioned on the outer left side of the fabric C as shown by the imaginary line in FIG. do. In addition, due to the supply of the pressurized fluid, in the process of the pressurized fluid being discharged from the inlet 73m through the turbine flade storage chamber 71 and into the tray 73n, the turbine plate 1' 73a is rotated at high speed by the pressurizing body. Drive to. As the turbine blade 73a rotates at high speed, the rotary blade 72 rotates at high speed with low torque. The sound of the rotation of the turbine plate 73a allows workers around the loom to recognize that cutting of the fabric is about to begin, while the pressurized fluid IJ1 outputs from the outlet 73n causes the fabric cutting guide 7
Dust such as fluff can be removed from inside the room.

Next, the cloth-wound roll A is moved and placed on the fully-wound cloth-wound roll stocker 5 by the forward movement of the above-mentioned dispensing mechanism 6, and the cover 74 is moved in the direction opposite to the above-mentioned direction of the cloth-wound roll A as shown in FIG. While the pressurized fluid is being supplied at the outside position,
Reverse the motor 77b. Then, the drive pulley 77C rotates in the direction opposite to the arrow shown in FIG. It comes into contact with the rotating blade 72 rotating at high speed and is cut. The cover 74 is then cut across the width of the woven fabric C as shown in FIG.
When the motor 77b is located outside the motor 77b, the rotation of the motor 77b and the supply of pressurized fluid are stopped.

After that, as shown in FIG. 9, the winding mechanism 8 causes the front roller side cut end Ca as the cut end of the woven fabric C to be wrapped around the entire cloth wrapping roll B of the front and rear rollers I l , 12.1'. It can be rolled. That is, first, air is injected from the blow-up nozzle 80 in the direction of the arrow X1, and after the front roller side cut end portion Ca is superposed on the entire cloth-wound roll B, the air injection from the blow-up nozzle 80 is stopped. Then, the cut end Ca on the front roller side is connected to the front roller 11 and the fully cloth-wound roll B.
As the roller 12 rotates as a result of the rotation, it passes between the rear roller 12 and the fully cloth-wound roll B while remaining superposed on the fully cloth-wound roll B, and protrudes downward. At this time, air is sent from the separation nozzle 81 and the blowing nozzle 82 to the arrow X3. It ejects in the X3 direction. Then, the cut end Ca on the front roller side 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 pipe 85 and the fully cloth-wound roll B are separated. The air from the blowing nozzle 82 flowing along the guide plate 83 blows the air between the fully cloth-wound roll B and the front roller 11, specifically from the vent bar 9 to 18. The woven fabric C connected to the front roller 11 is blown into the gate of the fully wrapped roll n, and wound around the roll opening with the narrowed fabric as shown by the dashed line. After this winding is completed,
Air injection from the separation nozzle 81 and the blowing nozzle 82 is stopped. This completes one cycle of cloth wrapping roll replacement work.

When one cycle of this 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 the cloth wrapped roll A on which a predetermined amount of fabric is wound on the fully wrapped cloth rolled roll stocker 5, moves and places it on the carrier, and assembles it on the carrier. After the full cloth-wound 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 A is supplied from the carrier to the fully cloth-wound roll stocker 2, the rod member 30 of the locking mechanism 3 is moved into the fully cloth-wound roll stocker 2 as the payout mechanism 6 moves back. Since the cloth-wrapped roll A has entered the cloth-wound roll A, the locking mechanism 3 holds the cloth-wound roll A in the full cloth-wound roll stocker 2 in preparation for the next cloth-wound roll exchange.

Therefore, according to this embodiment, the fabric roll can be replaced on the loom without stopping the weaving operation.
Moreover, even when using a carrier to replenish all cloth-wrapped rolls and to transport cloth-wound rolls with cloth wrapped around them, the cloth-wound roll located in the winding drive mechanism can only be wound at a predetermined amount (=I amount). Since you only have to do this while the work is done, the operating rate of the loom can be improved.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and may also be applied to, for example, the following structures (1) to (2), although illustrations are omitted.

(2) In the above embodiment, the cloth cutting device 7 is moved forward before the dispensing mechanism 6 is activated, and then the cloth cutting device 7 is cut in the backward motion after the dispensing mechanism 6 is activated. One movement of the fabric cutting device 7 to either the side frame 10 side or the other side frame l = IO side cuts the fabric, and the next time the fabric is cut, it is cut by moving it from the other side frame 10 side. .

(2) In the above embodiment, the fluid-driven motor uses a method in which the turbine blade storage chamber has a constant volume and the blades in this storage chamber are rotated by compressed fluid, but the method is not limited to this.
It is also possible to use a IIJ variable volume type, in which the capacity of the storage chamber J11 changes, as is used for hand tools such as impact wrenches.

Effects of the Invention As described above, according to the present invention, the pressure of the pressurized fluid supplied to the fluid-driven motor allows the motor to rotate at least 10,000 revolutions per minute, without using a gear train with a large gear ratio or a large motor. The structure of the device is I! In addition to being able to perform t'i elementalization, the woven fabric can be reliably cut even if no tension is applied to the woven fabric, and a device for applying tension is not required. Furthermore, since there is no electrical wiring on the moving rotary blade, there is no possibility of accidents such as damage to the wiring and ignition of fluff, thereby eliminating concerns about disaster prevention. Furthermore, since the rotary blade rotates at high speed, the speed at which the rotary blade moves in the cloth width direction can also be increased, so that the cutting work can be performed quickly.
