Is urged in the illustrated counterclockwise direction. Reference numeral 11 denotes a driving gear, which meshes with the driven gear 2 of the cross roller 1. Here, FIG. 2 shows a state in which the bearing 3 of the cross roller 1 is fixed by the cap 5, and as shown in FIG. The end portion 6a of FIG. 6 is detached downward from the restrained state by the stopper 9a by overcoming the elastic force of the stopper 9a, and is brought into the state shown in FIG. As a result, the cap 5 rotates clockwise about the fixed shaft 7, and the bearing 3 of the cross roller 1 is released from the cap 5. The guide 4 is inclined slightly downward toward the front of the loom (left side in the figure), and the front end 4a is convex, so that the cross roller 1 rolls to the front end 4a in front of the loom and stops.

Returning to FIG. 1, the drive gear 11 is
The driving force from the sprocket 19 is adjusted by a clutch 40 and transmitted to the shaft 14. The clutch 40 is a known device that adjusts the drive transmission force between the input shaft and the output shaft by the pressing force of a friction plate (a pressure receiving plate and a transmission plate). A transmission plate 40b is connected to the hollow shaft 19a of a certain sprocket 19,
The pressure receiving plate 40a is connected to the shaft 14 of the drive gear 11, which is the output shaft. Reference numeral 51 denotes a bush interposed between the hollow shaft 19a of the sprocket 19 and the shaft 14 of the drive gear 11, and the hollow shaft 19a and the shaft 14 are mounted so as to be relatively rotatable. Further, the transmission plate 40b is connected to the operation unit 41c, and detects a detection roller 33 as a feeler described later.
The operation unit 41 is operated by the forward / backward movement of the bolt 46 connected to

1c is pressed, the transmission plate 40
b and the pressure receiving plate 40a are in pressure contact with each other.

In this state, the weaving advances and the bolt 46 advances rightward in the figure in accordance with the amount of the cloth wound up on the cross roller 1, and the pressure contact force between the pressure receiving plate 40a and the transmission plate 40b increases to drive. Transmission power increases. Conversely, when the lever retreats leftward in the figure, the pressing force weakens and the drive transmission force decreases, and when the lever retreats further leftward, the bolt 46 separates from the operation portion 41c and the transmission plate 40b does not press the pressure receiving plate 40a. State.

The sprocket 19 is connected to a sprocket 20 fixed to the shaft 15 by a chain 18.
The shaft 15 is fixed to the frame 4 by bearings 16 and 17, and the gear 1 meshes with a gear (not shown) interlocked with the main shaft of the loom.

On the other hand, the frame 4 above the cross roller 1
A crank rod 31 is rotatably supported on the inner shaft 30. A detection roller 33 is attached to the crank rod 31. The detection roller 33 comes into contact with a cloth (not shown) wound around the cross roller 1 and rotates around the shaft 30 according to the winding diameter of the cloth. A crank lever 32 is connected to the crank rod 31, and a foot pedal 35 as connecting / disconnecting means is connected to the crank lever 32 via a spring 34 as an elastic member. The foot pedal 35 is an L-shaped member, and a foot step 35a is formed at one end thereof, and a middle bent portion thereof is a frame 4
The bracket 36 is fixed to the shaft 36a so as to be rotatable. The other end 35b of the foot pedal 35 is connected to one end of a lever 38 via a rod 37. An intermediate portion of the lever 38 is provided with a clutch 40.

The spring 39 is interposed between one end of the lever 38 and a spring seat 45 of a fixture 44 fixed to the frame 4 so that the lever 38 is attached to the other end of the lever 38. The bolt 46 presses the operating portion 41c of the clutch 40 by the urging force of the compression spring 39. The connection between the crank rod 31 and the bolt 46 is
It is configured as 0.

With the above construction, when the weaving of the loom progresses and a predetermined amount of cloth is wound on the cross roller 1, the work of removing the cross roller 1 from the loom during the operation of the loom is performed. By stepping on 35, the rod 37 moves rightward in the figure. Then, the lever 38 rotates counterclockwise against the spring 39, and the bolt 46 moves to the left in the drawing to be separated from the operating portion 41c of the clutch 40. Then, the transmission plate 40b is in a clutch disconnected state in which the pressure receiving plate 40a is not pressed.

In this state, since the driving gear 11 is not driven to rotate, the cross roller 1 can be manually rotated, so that the cross roller 1 can be easily removed. Next, with the foot pedal 35 depressed, the operating lever 6 is pushed upward with one hand as shown in FIG. 3 to separate the cap 5 from the bearing 3 of the cross roller 1. Then, the bearing 3 rolls to the tip 4 a while being guided by the guide 4 of the bracket 25. Thereafter, the cross roller 1 is rotated by a small amount and cut at a position such as a cut mark. At this time, since the cross roller 1 is not driven, the cross roller 1 is pulled by the cloth tension, and there is no risk of inadvertent movement, which is safe. After that, the sheet is conveyed by the conveyance cart to a subsequent process such as a detection device. When the empty cross roller 1 is placed, the procedure reverse to that described above may be performed.

[0013]

As described above, according to the present invention, the drive of the cross roller is stopped by depressing the foot pedal inside the frame when the cross roller is detached during the operation of the loom. The cross roller can be taken out with both hands, so the cross roller can be taken out with both hands while the foot pedal is depressed, and the workability is extremely high, and the work time can be reduced. .
