Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cloth winding roll winding device for a loom equipped with a roll changing device for automatically changing a fully wound cloth winding roll.

[0002]

2. Description of the Related Art A loom equipped with a cloth roll changing device is known, for example, as disclosed in Japanese Patent Laid-Open No. 25750/1993.

In this apparatus, a winding mechanism is driven to rotate the cloth winding roll to wind the woven cloth, while an empty roll stock mechanism (roll stocker) above the winding position preliminarily sets an empty cloth winding roll , Called empty roll). Then, when the cloth winding roll at the winding position reaches a predetermined cloth winding amount, the fully wound cloth winding roll (hereinafter, referred to as a full winding roll) is discharged to the front of the loom with the woven fabrics in series, and then the empty roll. After dropping the empty roll from the stock mechanism to the winding mechanism via the guide rail, after cutting the woven cloth between the fully wound roll delivered to the front of the loom and the empty roll mounted at the winding position, The end of the woven fabric cut by the winding mechanism is wound around an empty roll.

In the payout means, a rail-shaped bracket piece that normally extends in the vertical direction is rotated when it is fully wound, and the bracket piece is arranged so as to be inclined in the horizontal direction so as to project, and transferred onto this. The winding roll rolls due to the gradient and moves to the carry-out position by its own weight.

[0005]

A loom equipped with a cloth roll changing device as described above is provided with a drive means by a torque motor for appropriately controlling the rotation of the cloth winding roll when the cloth winding roll is replaced. That is, the drive means is provided separately from the motor that rotates the main shaft of the loom. Therefore, there is an inconvenience that the cost is increased and the device is increased in size.

In order to solve such inconvenience, it has been attempted to utilize the rotation of the loom main shaft without using a driving means by a torque motor even in a loom equipped with a cloth roll changing device. However, when using spindle rotation,
There has been a problem that it is often difficult to control the rotation of the cloth winding roll winding device. Generally, the cloth winding roll is rotated by engaging a drive gear with a gear provided on the cloth winding roll or engaging a member such as a dog clutch with an engaged groove formed in the cloth winding roll. However, when the driving force is cut off, a load due to torque is applied to the mutual meshing surfaces when the driving force is cut off, and this load increases the frictional force of the meshing portion. It cannot be cut off smoothly during driving.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a cloth-roll-roll winding device which can downsize a loom equipped with a cloth-roll changing device and reduce the cost.

[0008]

In order to achieve the above object, the present invention is provided on the left and right side frames of a loom so as to be rotatable and to face each other on the same axis so as to be relatively close to and away from each other. A pair of chucks, a chuck operating means for bringing the chucks close to each other to support the cloth-wrapping roll at both ends, and separating and releasing the cloth winding roll; and a chuck provided on at least one of the two chucks operated by the operating means. Engagement means that engages with the engaged portion of the cloth-wrapping roll and disengages due to the separation, and the rotational drive from the loom main shaft is transmitted to the chuck provided with this engagement means through the clutch,
A rotation transmission mechanism for rotationally driving the cloth winding roll, and a clutch operating mechanism for disengaging the clutch when the operating means is operated to separate the pair of chucks and release the cloth winding roll. .

[0009]

According to the present invention, since the rotation of the loom main shaft is utilized when the rolls are replaced without providing the driving means by the torque motor, the space for mounting the driving means is unnecessary, and the loom can be downsized. The cost can be reduced. Further, since the rotary drive transmission mechanism is provided with the clutch, the transmission of the rotary drive from the loom main shaft can be cut off by disengaging the clutch, and the engaging means can be easily disengaged even while the loom is in operation. Therefore, the rotation of the cloth winding roll can be smoothly controlled.

When 6 pushes out, the push-out lever 130 is rotated counterclockwise around the attachment pin 131 via the connecting spring body 133, and the cloth-wrapping roll 3 of the full-winding roll 3a is pushed out. As a result, the end of the cloth winding roll 3 rolls on the rolling surface 115 of the main bracket 111 and the rolling surface of the slide member 141 to reach the support seat 143, and is held in this groove. In addition,
The stopper 144 prevents the cloth winding roll 3 from falling off the support seat.

The rotation of the operating body 121 causes the positioning stopper 121 via the connecting rod 129 to rotate the operating lever 178 in the counterclockwise direction in conjunction with this operation, so in step P5, the connecting lever 183 is operated. The stop lever 180 is rotated clockwise about the pin 179. As a result, the roller 180a becomes the empty roll 3b.
Although the guide pin 171 falls off the moving path of the empty roll 3b and falls while being guided by the guide member 171, the stopper pin 178a is blocked by the stopper pin 178a while falling because the stopper pin 178a projects into the passage of the empty roll 3b due to the downward movement of the operation lever 178.

Next, in step P7, the supply of pressure air to the positioning operation body 125 is cut off at a timing after the cloth winding roll 3 of the full-winding roll 3a has passed through the receiving portion 124 in step P6, and a built-in spring is used. The connecting member 126 is moved to the left in FIG. As a result, the receiving portion 124 and the pushing lever 130 return to the state shown in FIG. Further, since the operation lever 178 is rotated in the clockwise direction via the connecting rod 129, the stopper pin 178a does not prevent the empty roll 3b from falling, so that the empty roll 3b is prevented.
Is guided by the guide member 171 and the main bracket 11
1 falls on the rolling surface 115 and is held at a predetermined position by the receiving portion 124 and the pushing roller 132.

In parallel with this, in step P8, when the full roll 3a is supported by the support seat 143 in step P6, the weight of the full roll 3a causes the slide member 141 to move over the rollers 112a and 112b as shown in FIG. Slides to the left, moves until the roller body 112a is prevented from sliding, and reaches the carry-out position 7.

In step P9, the presence of the ON signal from the limit switch LS is detected to determine whether the empty roll 3b is seated. At this time, if the ON signal does not exist, the detection operation is repeated a plurality of times, and if it cannot be detected even further, it is determined that the empty roll supply is defective, and the operation thereafter is stopped, and an abnormality is displayed. When the ON signal is detected, the process proceeds to step P10. In step P10, the chuck operating body 3
The supply of pressurized air to 9 is interrupted, and the output shaft 43 is retracted by the built-in spring. As a result, the elastic bodies of the compression spring 33 move the chuck bodies 29 and 49 toward the empty cloth roll 3b. In this moving process, first, the taper portion 31c of the roll holding portion 31 enters the holding hole 4, and the empty cloth winding roll 3b is automatically aligned and centered.
A is fitted and brought into contact with the contact portion 31b. In the drive chuck 25, in this process, the engaging claw 36 is engaged as it is if it is opposed to the engaged groove 5, and if not, the engaging claw 36 is pushed by the end surface of the empty cloth winding roll 3b. Although it is rotated counterclockwise in FIG. 4 against the compression spring 37 and retracted, the centering portion 31a is fitted in the holding hole 4.

Next, in step P11, pressurized air is supplied to the wrapping actuator 203, and the output shaft 205 projects to rotate the arm 202 around the support pin 201 in the clockwise direction in FIG. By this rotation, the winding and cutting means 20
The woven cloth guide 207 of No. 5 lifts the woven cloth W from below, and the rotary roller 208 contacts the above-mentioned empty cloth winding roll 3b through the woven cloth W.

Next, in Step P12, the self-propelled motor 210 is operated while the rotary cutter 212 is rotated, and the woven fabric W is cut in the width direction by the rotary cutter 212.

Next, in step P13, water is jetted from the water jet nozzle 209 to wet the woven cloth W in contact with the blank cloth winding roll 3b, and the cloth W is attached to the blank cloth winding roll 3b by the adhesive force of the water.

Next, at step P14, when the supply of the pressurized air to the clutch operating body 90 is cut off, the elastic force of the spring 85 causes the operating lever 83 to rotate clockwise in FIG. The driven side is pressed to put the clutch 68 into the continuous state. As a result, the rotational movement of the sprocket 65 is transmitted to the first transmission shaft 61, and thus the winding drive shaft 23.
The chuck body 29 is rotated via.

By this rotation, when the engaging claw 36 is engaged with the engaged groove 5, the empty cloth winding roll 3b is rotationally driven.
Further, when not engaged, only the chuck body 29 rotates, so that the engaging claw 36 engages with the engaging groove 5 when facing the engaging groove 5, and thereafter, as described above, the empty cloth winding roll 3b. Rotate.

Next, in Step P15, immediately after the water injection of the water injection nozzle 209, pressure air is injected from the air injection nozzle 300 to blow the woven cloth W toward the blank cloth winding roll 3b to further strengthen the attachment. At the same time, the front end of the woven cloth W is blown to adhere it to the side of the blank cloth winding roll 3b. As a result, the woven fabric W is wound without bending the tip of the woven fabric W.

Next, at step P16, immediately after the woven cloth W is cut, the supply of the pressurized air to the wrapping actuator 203 is stopped, and the output shaft 205A is retracted by the built-in spring. Returns to the position of the chain double-dashed line in FIG.

After that, the full roll 3a is carried out by the carrier and the empty roll 3b is moved to the empty roll stock position 184.
Supply to. As a result, the series of work of replacing the cloth-wrapping roll is completed.

In this embodiment, the full roll is transferred to the transport vehicle at the carry-out position, but after step P16, the slide member 141 is retracted to the standby position 7a to secure a wide passage, You may make it carry out in the standby position 7a.

When the rotation of the cloth winding roll is directly driven by the main shaft of the loom as in this embodiment, a motor for rotating the cloth winding roll is not required, so that the loom can be constructed at a low cost and in a small size. it can. Further, when the rotation of the chuck is stopped, the drive transmission from the main shaft is blocked by the clutch, so that the engaging claw can be easily disengaged from the engaged groove of the cloth winding roll. Further, in the present embodiment, the rotation driving force is transmitted to the cloth winding roll by the engaging claw and the engaged groove, but the cloth winding roll may be rotated by meshing the gears.

[0059]

As described above in detail, according to the present invention, in the loom having the cloth winding roll changing device, since the rotation of the main shaft is utilized without providing the driving means by the torque motor, the installation space for the torque motor is unnecessary. Therefore, the loom can be downsized, and the cost can be reduced accordingly. Also, since a clutch is installed in the rotary drive transmission mechanism, the clutch is disengaged when the cloth roll is released by separating the pair of chucks that support the cloth roll at both ends. It is possible to easily disengage the meshing means and easily release the cloth winding roll even when the loom is in operation.
