Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a winding device for a loom, and more particularly to a cross roller support and drive device.

<Prior Art> As a conventional winding device, there is one shown in FIG. 1, for example.

To explain this, the bearing 2 is attached to the frame 1 of the loom.
3, a cross roller drive shaft 4 is rotatably supported.

A drum 7 is fixed to the cross roller drive shaft 4 by a key 5 and a bolt 6, and a sleeve 9 is rotatably fitted through a bush 8. A sprocket throat 10 and a ratchet notopoil 11 are integrally formed on the sleeve 9, and a chain 12 from a surface roller drive system driven by the main shaft of a loom (not shown) is wound around the sprocket O. A ratchet throat 4 pivotally connected to a pin 13 protruding from the frame 1 is engaged with the ratchet wheel 11. Also, the sleeve 9 has a bolt 15.
15ii16 is fixed, and a pin 17 is attached to this arm 16.
The shoe 18 attached via the drum 7 is brought into pressure contact with the drum 7.

In this way, the chain 1 is moved by the surface roller drive system.
The sleeve 9 is rotated via the sleeve 2 and the sprocket 10, and the cross roller drive shaft 4 is rotated via the drum 7 due to frictional contact between the drum 7 and the shoe 18 that rotates together with the sleeve 9. Note that the ratchet wheel 11 and ratchet 13 are provided to prevent reverse rotation.

A cross roller 19 is provided at the tip of the cross roller drive shaft 4.
A notched fitting part 21 is formed as shown in FIG. 2 on which the minimum diameter part 20a of the shaft end of the cross roller 19 is placed and fitted. After placing the coupling 23, which is slidable in the axial direction of the cross roller drive shaft 4 via the key 22 and is attached to the rotation direction G, to the left in FIG. Middle part 20b of the shaft end of the cross roller 19
to fit. At this time, the engaging part 24 formed at the end of the coupling 23 is engaged with the engaging part 25 formed at the large diameter part of the shaft end of the cross roller 19, and in this state, the U-shaped chestnut knob 264 This prevents the coupling 23 from coming off.

In this way, the cross roller drive shaft 4 and the cross roller 19 are integrated, and the cloth is wound up by rotating the cross roller 19.

By the way, looms, especially high-speed looms such as fluid-jet looms, are operated at several times the speed of ordinary looms, so the mechanism is designed to adjust the amount of warp threads on the warp beam in order to reduce the frequency of work. Increase the warp winding diameter (800-100
100O, and as a reaction to this, there is a tendency for the work of removing cloth while the loom is in operation (the work of removing the cross rollers from the machine stand in order to remove the woven fabric wound around the cross rollers from the machine stand). Since it is preferable to maintain a high operating rate of a loom from the viewpoint of productivity, it is desirable to replace the cross rollers while the loom is in operation during cloth cutting work.

However, in the conventional device described above, first slide the camp ring 23 to the right in FIG.
9, the cross roller 19 is then reversed, and the woven fabric wound around the cross roller 19 is unwound by the amount necessary for the next winding described above. If the opening of the fitting portion 21 faces downward when the roller is removed, there is a possibility that the cross roller 19 may fall off, resulting in a problem of poor operability. Also, coupling 2
3 is difficult to remove due to the relationship between the tension of the woven fabric and the 1-lux of the cross roller drive shaft 4, making it difficult to perform the work.

<Object of the Invention> In view of these conventional problems, an object of the present invention is to provide a winding device in which there is no danger of the cross rollers falling off and the cross rollers can be easily replaced.

<Structure of the Invention> For this reason, the present invention supports both ends of the cross roller,
In addition, the cross roller can be freely attached and detached with a single touch, and a ramp mechanism is fixed to the frame of the loom, and independently of this, these are installed between one end of the cross roller and the drive source of the cross roller with a single touch. A latch mechanism is provided so that it can be moved in and out.

<Example> The embodiment shown in FIGS. 3 to 6 will be described below.

In FIG. 3, the woven fabric C is moved to the guide roller 3.
1. The fabric passes through a weave density adjustment mechanism consisting of a surface roller 32 and a press roller 33, then passes through a guide no. 34 and is wound around a cross roller 19.

The clamp mechanism 35 for rotatably supporting the cross roller 19 is constructed as shown in FIGS. 3 to 6.

That is, a bushing 37 for a semi-open bearing is fixed to the main body 36 fixed to the frame 1, and a clamp 39 and a bush 40 for a bearing of a stone slide are fixed to the main body 36, one end of which is pivoted by a pin 38. be. A lever 42 is pivotally attached to the other end of the clamp 39 by a pin 41, and a hook 43 is fixed to the lever 42. In addition, the main body 36
A hole 44 is provided in the hole 44 for engaging a hook 43.

Therefore, after placing and fitting the shaft end portion 45 of the cross roller 19 on the bushing 37 on the main body 36 side,
2, tighten the clamp 39 around the bottle 38 as shown in Fig. 3.
lN moves in the same direction, the lever 42 itself also rotates in the same direction around the bottle 41, and the hook 43 is brought into engagement with the hole 44, thereby bringing the clamp mechanism 35 into the closed state, J- The shaft end portion 45 of the cross roller 19 can be rotatably supported by a receiving portion formed by a bush 37 on the main body 36 side and a nozzle 40 on the clamp 39 side. Moreover, if the lever 42 is operated counterclockwise in FIG. 3 from this state, the hook 43 and the hole 44 are first disengaged, and the clamp mechanism 35 becomes in the open state (the state indicated by the chain line in FIG. 3). .

Incidentally, the ramp mechanisms 35 are provided inside the left and right frames 1 of the loom, respectively, in order to support both ends of the cross roller 19.

A clutch mechanism 46 for connecting and separating the cross roller 19 and its drive shaft 4 is constructed as shown in FIGS. 4 to ff1G.

That is, a hole 4 is formed in the axial center of the tip of the cross roller drive shaft 4.
7 is formed, and an engagement shaft 49 is mounted in this hole 47 via a key 48 so as to be slidable in the axial direction and integrally in the rotational direction. An engagement pin 50 is fixed to the tip of the engagement shaft 49 in a direction perpendicular thereto. Then, a ring 51 with a flange having an inner diameter slightly larger than the length of the engaging pin 50 is placed over the engaging pin 50, and a cover 52 is fixed to prevent it from coming off.

Further, a hole 53 is formed in the shaft center of the shaft end portion 45 of the cross roller 19 on the side facing the cross roller drive shaft 4, and a hole 53 is formed in the outer circumferential portion of this hole 53 for engaging the retaining pin 50. A notch 54 is formed.

Further, the intermediate portion of the lever 57 is pivotally connected to a pin 56 protruding from a bracket 55 fixed to the frame 1.
Elongated holes 58 formed in the forked portions at the tips of the rings 7 are fitted into pins 59 protruding from the outer peripheral surface of the ring 51.

Therefore, the lever 57 is operated counterclockwise in FIG. By engaging the clutch mechanism 46, the rotation of the drive shaft 4 is controlled by the key 48,
Engagement shaft 49, engagement pin 50, and notch 54 in shaft end 45
(the state indicated by the chain line in FIGS. 4 and 5), in which the signal is transmitted to the cross roller 19 via the cross roller 19. Moreover, if the lever 57 is operated clockwise in FIG. 5 from this state,
The engagement pin 50 moves to the right via the ring 51 and comes out of the notch 54 of the shaft end 45, and the clutch mechanism 46 enters a disconnected state (solid line state).

In order to lock the lever 57 in each position when the clutch mechanism 46 is connected or disconnected, the lever 57 is provided with a recess, and the bracket 55 is
Two stoppers 6o are provided.

As described above, when installing the cross roller 19, first clamp both ends of the west roller 19 with the clamp mechanism 35 to support it rotatably, and then connect the clutch mechanism 46 to attach the cross roller. It is connected to the drive shaft 4 and rotates in relation to the operation of the machine.

In addition, when replacing the cross roller 19, that is, when lowering the cloth, first disengage the clutch mechanism 46 with the lever 57, and rotate the cross roller 19 in reverse by hand in order to secure the cloth to be wrapped around the next new cross roller. Then cut the fabric. At this time, the cross roller 19 is reliably supported by the clamp mechanism 35, and the connection between the cross roller 19 and its drive shaft 4 is disconnected, so this work can be performed extremely easily and safely. . Thereafter, the clamp mechanism 35 is released by the lever 42, the cross roller 19 on which the woven cloth is wound is removed from the machine frame, and a new cross roller is installed in the same manner as described above for installing the cross roller.

Note that the clamp mechanism and clutch mechanism are not limited to those shown in the drawings, and may be any one-button mechanism that meets the gist of the present invention.

<Effects of the Invention> As explained above, according to the present invention, the clamp mechanism for rotatably supporting the cross roller and the clutch mechanism for connecting and separating the cross roller and its drive source are independent of each other. Furthermore, since the clamp mechanism itself is fixed to the frame of the rtqa and does not rotate, the effect of attaching and detaching the cross roller can be performed extremely easily and safely.
