Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a connecting and disconnecting device for a bobbin carrier that travels along a traveling rail installed in a spinning factory and conveys a roving bobbin, an empty bobbin, and the like. It is a thing.

(Prior Art) Conventionally, when a roving bobbin of a spinning machine becomes empty, a method of replacing the roving bobbin with a new full roving bobbin is generally hung on a roving bobbin on a roving bobbin carrier and a spinning machine creel. There is a method of manually replacing and replacing the empty bobbin. However,
According to this method, it is necessary to lift a heavy roving bobbin of about 2 to 3 kg to the creel at a considerably high position, which causes a considerable amount of hard work for the worker and causes a decrease in work efficiency.

As a method for improving this problem, as shown in FIG. 30, a preliminary roving winding transport path 133 having substantially the same height position as the creel 132 is arranged along the spinning machine 131, and the roving winding is performed in a single row. 1
A method has been put into practical use in which a roving reel is automatically loaded outside the spinning machine group into a number of transportation magazines 135 that hang and transport 34, and the roving is transported to the spinning machine. For example, 9/55
As shown in FIG. 31, Japanese Patent Publication No. 55-36731 published on March 24, a main conveyance path 137 is provided along the outer circumference of the roving frame 136 and the spinning frame 131, and the roving frame wound by the roving frame 136 is installed. A method has been proposed in which a bobbin is carried into a preliminary roving winding transport path 133 via a main transport path 137.

However, in order to automatically convey the roving winding in this conveying method, the number of preliminary roving windings carried into the preliminary roving winding conveying path 133 needs to be the same as the number of spindles in the roving machine 136 or an integral multiple thereof. is there. However, when changing a factory equipped with existing equipment or one of the roving or spinning machines to new equipment, the number of spindles of the roving machine and the number of spindles of the spinning machine (that is, the preliminary It is difficult to establish such a relationship with the number of spools). For this reason, there is a problem that the automatic transfer of the preliminary roving spool cannot be performed properly between the roving process and the spinning process.

In order to solve this problem, the inventors of the present application made it possible to separate the transport body traveling along the traveling rails installed between the roving and spinning processes at a predetermined position, and to remove the roving to the preliminary roving winding rail of the spinning machine. The present invention has invented a method of adjusting the carrier by dividing it at a predetermined position according to the required number when carrying the bobbin.

(Problems to be Solved by the Invention) The present invention is capable of performing roving / spinning even when the number of preliminary roving rolls carried into a preliminary roving roll rail of a spinning frame is equal to or not an integral multiple of the number of spindles in the roving frame. It is possible to simplify the structure of the connecting / disconnecting device for bobbin conveyors required for automatically carrying the preliminary roving winding between the steps, and also to use the driving mechanism of the multiple connecting / disconnecting devices as one driving mechanism. To do so.

Is a rail 6 in the roving frame of the roving frame 2 which requires an empty bobbin.
And the corresponding connecting rail 12 and the bridge rail mounting portion 8b stop at the corresponding positions. Next, the motor 24 is driven in the normal direction, and the support body 23 is rotated in the clockwise direction in FIG. 6 about the support shafts 21a and 22a. When the support body 23 is rotated, the engagement roller 17 mounted on the support plate 23 causes the engagement plate of the connection rail 12 to move.
By engaging with 18, the connecting rail 12 is rotated in the clockwise direction in FIG. 6 around the pin 15 as the support plate 23 rotates. Support plate 23
6 is rotated by 90 degrees from the position shown in FIG. 6, the electromagnetic brake 25 operates, the motor 24 stops, and the support plate 23
Is stopped and held at the same position. As a result, the connecting rail 12

Next, the motor 28 is driven to rotate the screw roller 26. Also, the torque motor 35 is driven in this state,
The latch lever 37 is rotated from the position shown by the solid line in FIG. 14 to the position shown by the dashed line in parallel with the traveling rail 11. With the rotation of the latch lever 37, the entire carrier 30 along with the support 31 is moved to the bridge rail 16 side. And the latch lever
During the rotation of 37, the engagement roller 32 equipped on the support body 31 locked by the latch lever 37 is engaged with the screw portion 26a of the screw roller 26, and the screw roller 2
By the action of 6, it is moved to the rail 6 side in the roving frame along the bridge rail 16 and the engagement with the latch lever 37 is released. The screw roller 26 continues to rotate in a state where the latch lever 37 is held in a position parallel to the traveling rail 11,
The engaging roller 32 of the carrier 30 is successively engaged with the screw portion 26a of the screw roller 26, and the carrier 30 is carried into the rail 6 in the roving frame.

Then, as shown in FIG. 17 (b), the drive of the motor 28 is stopped and the rotation of the screw roller 26 is stopped when the rear end of the conveying body 30 passes the position corresponding to the rotating lever 80 of the sorting device 79. Then, the conveyance of the carrier 30 is stopped. In this state, the drive motor 89 of the drive device 87 is driven and the rod 90 moves to the first position.
17 (a) and 17 (b) are moved to the left, and accordingly, the operating rod 68 and the rod 65 are also moved to the left in the same figure. When the operating rod 68 moves to the left from the position shown in FIGS. 17 (a) and 17 (b), the pin 84 projecting from the turning lever 80 of the sorting device 79 is pressed by the operating rod 68, and the rotation is turned. The moving lever 80 is rotated counterclockwise in FIG. 18 to move the engaging roller 32 to the supporting member at the rear end of the carrier 30 as shown in FIG. 18 (a).
The engaging roller 32 of 31 is held at a position to guide it to the guide rail 6b.

Next, the motor 28 is driven again to drive the screw roller 26, and the carrier 30 and the connector 52 are moved to the left in FIG. 17 (b). Then, as shown in FIG.
When the connecting mechanism 53 of the 30 and the connecting body 52 moves to the position corresponding to the connecting / disconnecting device 63, the motor 28 stops and the carry-in is stopped. Next, the drive motor 89 of the drive device 87 is reversely driven, and the rod 90 is moved to the right in FIG. With the movement of the rod 90, the operating rod 68 moves integrally with the rod 65 to the right in the figure by the spring force of the compression spring 70. With the movement of the rod 65, the release lever 72 and the holding lever 74 are rotated in the clockwise direction in the figure and the holding lever 75 is rotated in the counterclockwise direction, so that the support body 31 located at the rear end of the carrier 30 is rotated. Engaging roller
32 is held by both holding levers 74 and 75. On the other hand, the latch lever 60 of the latch mechanism 54 is pressed by the roller 72a of the release lever 72 and rotated in the clockwise direction in FIG. 18 (b), and the hook portion 60a of the latch lever 60 and the latched mechanism 55. The engagement with the pin 61 is released. In this state, the motor 28 is driven in the reverse direction, the connecting body 52 is moved to the right in FIG. 19 (b), and is unloaded from the inside rail 6 of the roving frame.

The motor 28 stops when the engagement roller 32 of the connecting body 52 and the screw portion 26a are disengaged. Then, the torque motor 35 is driven in the reverse direction, and the latch lever 37 held in the position parallel to the traveling rail 11 is rotated clockwise in FIGS. 14 and 15. The slide member 41 engages with the engaging portion 31a of the support member 31 during the rotation of the latch lever 37, and the latch lever 37 is further rotated from that state, which is shown by a chain line in FIGS. 14 and 15. Thus, the slide member 41 moves into the tubular portion 40 against the spring force of the tension spring 44. Then, when the engagement between the engaging portion 31a and the leading end of the slide member 41 is released, the slide member 41 returns to the projecting position by the action of the tension spring 44. Then, the engaging portion 31a moves along the guide groove 39 as the latch lever 37 rotates, and the connecting body 52 moves. The drive of the torque motor 35 is stopped when the tip of the engaging portion 38 of the latch lever 37 engages with the stopper 45, and the engaging portion 31a of the support body 31 is engaged with the latch lever as shown by the solid line in FIG. 3
It is held in a state of being hooked in the guide groove 39 of 7. Next, the motor 24 is driven and the bridge rail 16 is rotated to the retracted position. Then, the transporter 8 moves along the main transport path 3 to the transport body 30.
It moves to a position corresponding to the spare roving winding rail 5, the standby rail 7 or the roving inside rail 6 which requires the pulling out and stops at that position.

The carrying-in of the carrier to the preliminary roving winding rail 5 or the standby rail 7 is slightly different in the carrying-in to the rail 6 in the roving frame and the operation method of the decoupling device 62 at the time of carrying-in. Since the carriers 30 are carried in zigzag on the inner rail 6 of the roving frame, a sorting device 79 is arranged at the end of the inner rail 6 of the roving frame, and the connection releasing device 63 operates in two stages in relation to the sorting device 79. However, in the case of the spare roving winding rail 5 or the standby rail 7, since there is no distribution device 79, the connection releasing device 62 is operated in one step. That is, after the bridge rail 16 is connected to the preliminary roving winding rail 5 or the standby rail 7, the rod 63 is operated so that the release lever 72 and the holding levers 74 and 75 are rotated to the retracted position.
