Description

[Detailed description of the invention] The present invention uses an automatic winder to remove the supply pipe thread when it runs out or is cut in the middle and cannot be spliced. This relates to a device that grasps the yarn of the new yarn in a pulled-out state in order to easily and securely join the yarn in a device that releases the yarn from the winding position and replaces it with a new yarn. A magazine 1 in which threads 2 are arranged at equal intervals on the circumference is rotatably provided, and a pipe yarn a with a cap yarn b stored in the hollow of a bobbin is stored in the holding cylinder 2 with the cap yarn b facing upward. The center shaft 3 of the magazine 1 is formed hollow and its lower end communicates with a negative pressure source, and a suction nozzle 18 is provided on its upper surface that communicates with the center shaft 3 and projects into the space between the holding cylinders 2. The suction port 19 of the magazine 1 is closed by a normally closed shutter 20 on which a spring 22 is applied, and a receiving piece 23 for opening the shutter, which projects downward from the shutter 20, is connected to the upper part of the tube thread a that is moved by the rotation of the magazine 1. It is made to protrude into the movement trajectory.

Embodiments of the present invention will be described with reference to the drawings.

1 is a magazine which is rotatably provided with several tube holding cylinders 2 disposed on the circumference around a central axis 3;
The thread a, with the thread b stored in the hollow part of the bobbin, is stored in the holding cylinder 2 by hand, or the thread a is transferred by a delivery conveyor 4 installed on the side of the magazine 1, as shown in the illustrated example. , by reversing the guide plate 5 at the appropriate time, the pipe yarn a on the conveyor 4 is moved to the second position according to the guide plate 6.
The thread b is inserted and held upward in the holding cylinder 2 at position A in the figures and Fig. 3, and when a thread breakage occurs in the thread winding section, the swinging piece is moved by the operating rod 7 which moves downward in response to a detection command. 8 is actuated, and an arm piece 9 interlocked with this rotates the magazine 1 through an actuating mechanism 10 by a distance of one pitch between the holding cylinders 2 about the fixed central shaft 3. As a result of this rotation, the holding cylinder 2 that has supplied and accommodated the pipe yarn a at position A moves to position B, and further moves to position C in the next rotation.
In positions A and B, the pipe yarn a in the holding cylinder 2 is moved by the base plate 11 provided on the lower surface of the magazine 1.
It is supported by the holder and moves by sliding on the upper surface, but in position C, it is located directly below the holding cylinder 2 and has a hole 12 (shown in FIG. 1) in the base plate 11, so that the The support is released and falls from inside the holding cylinder 2,
It is housed in a guide tube 13 provided on the lower surface of the
The lower end of the fallen pipe a is supported by the tray 14.
The receiving tray 14 is divided into two parts so as to open left and right, and when this is opened by a command, the pipe thread a falls and is inserted into the peg 15 directly below it, and then the peg 15
As shown by the dotted lines in the figure, the thread is returned to the winding position, and at the same time, the thread b is taken out and spliced to perform the thread winding operation.

In the above-described new pipe yarn supply device for an automatic winder, the center shaft 3 of the magazine 1 is hollow, the lower end thereof is always communicated with a negative pressure source, and the catch plate 17 is attached to the upper end of the center shaft 3 with a set screw 16. Furthermore, a suction nozzle 18 with an open bottom surface is fixed to the upper surface of the catch plate 17, the inside of the base end thereof communicates with the central shaft 3, and the tip protrudes laterally from the catch plate 17, and the protruding end The bottom surface of the shutter is a suction port 19, and one end of a shutter 20 that opens and closes the opening is attached to a shaft 21 on a catch plate 17.
The suction port 19 is rotatably attached to the shaft and energized by a spring 22 so as to always close the suction port 19. The suction port 19 is located between the holding tubes 2, 2 in B and C shown in FIGS. The receiver piece 23 is moved into the magazine 1 so that the upper part of the pipe yarn a accommodated in the magazine 1 collides with the receiver piece 23.
It was made to protrude into the locus of movement of the upper part of the pipe thread a, which is moved by the rotation of the pipe. In this way, the pipe yarn a stored in the holding cylinder 2 at the position A with respect to the magazine 1 moves to the position B and waits as shown in FIG. 2 due to the rotation of the magazine 1 during the previous pipe supply operation. . Next, when the magazine 1 rotates one pitch in response to a yarn supply instruction and the yarn a from position B moves to position C, which is the dropping position with respect to the peg 15, the receiving piece 23 is pushed with the upper part of the yarn a to move the shutter 20. It rotates against the spring 22, opens the suction port 19 of the nozzle 18, connects the central shaft 3 to the outside air through the suction port 19 of the nozzle 18, and passes through the lower surface of the suction port 19 by the suction outside air flow. This device sucks the opening thread b of the pipe thread a and causes it to be sucked into the central shaft 3.
The thread b, which has been sucked and held by the user, falls while being stretched and is stored in the lower guide tube 13, and as a result of the fall, the shutter 20 is automatically returned by the spring 22, and then in the operation of exchanging the old and new threads. After the pipe yarn a is inserted into the peg 15, when it is held at the winding position, the opening yarn b connected between the pipe yarn a and the central shaft 3 is guided to the splicing operating position. In this action, in order to ensure proper suction of the thread b by the suction port 19, the mounting height of the catch plate 17 with respect to the central shaft 3 is adjusted, and the position of the suction port 19 is adapted to the height of the pipe thread a. I did it like that.

According to the present invention, a suction nozzle 18 communicating with the hollow interior of the central shaft 3 is provided on the upper surface of the hollow central shaft 3 whose lower end communicates with a negative pressure source, and a suction port 19 on the lower surface thereof.
A normally closed shutter 20 is provided for closing the shutter, and a receiving piece 23 is provided downwardly from the shutter 20,
Since the shutter 20 is opened by pushing the receiving piece 23 at the upper part of the pipe a in the holding cylinder 2, which moves on the lower surface of the suction port 19 in conjunction with the rotation of the magazine 1 when supplying the pipe, This has the effect of smoothly and reliably drawing out the stub b of the pipe a and suctioning and holding the stub b into the hollow of the central shaft 3, thereby further facilitating automation of the winder.
