Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an automatic winder lead-out device for performing yarn end lead-out processing in advance when supplying a spun yarn to an automatic winder.

[0002]

[Prior art]

 The yarn produced by the spinning machine is inserted into a tray and conveyed by a conveyor to an automatic winder factory adjacent to the spinning factory. In the spinning machine, the yarn end is wound around the bobbin several times so that it does not get entangled with the surroundings while the yarn is being conveyed on the conveyor. ing. On the other hand, in the automatic winder, when unwinding the yarn carried in the tray and winding it into the package, if one yarn becomes empty, the next yarn is taken in continuously and the yarn end of that yarn and the package The yarn ends are spliced together and wound up to form a package.

In the automatic winder, in order to smoothly perform the yarn splicing, the yarn end of the tubular yarn introduced into the automatic winder is subjected to a yarn end tapping process in a predetermined state, and the automatic winder quickly and reliably It is necessary to splice. For this reason, a yarn end tapping processing station is installed on the conveyor line that conveys the yarn from the spinning machine to the automatic winder.

A rotating disk-shaped turret is provided in the outlet processing station, a plurality of approximately half-moon shaped tray accommodating grooves are equidistantly provided on the outer circumference of the turret, and a spinning machine is provided around the outer circumference of the turret. A station that cuts the thread end wound around the bobbin thread while rotating it in the direction opposite to the thread winding direction, and a thread end that has been taken out on the bobbin outer circumference while rotating the tube thread in the thread winding direction. A station for lightly winding, a station for rotating the tube yarn in the opposite direction to the winding direction of the yarn, and a station for unwinding while holding the end of the yarn lightly wound on the outer circumference of the bobbin with the suction mouth while holding it with the suction mouth. Each of the stations has a station for cutting the yarn end with a predetermined length while holding the end and for hanging the yarn end from above into the hollow part of the bobbin.

When the yarn end wound around the tubular yarn is cut with a rotary cutter or the like during the yarn end tapping operation at each station, the yarn bunched around the tubular yarn is not cut properly. However, in that case, it is not possible to perform the subsequent process of finding out. For this reason, after the cutting station using a rotary cutter, etc., a searcher is provided that scoops off the yarn in the backwind part wound around the bobbin and cuts this yarn to release the yarn end.

In the searcher, a searcher piece consisting of a thin tongue piece is pressed against the outer circumference of the bobbin that is moved by the rotation of the turret with a spring to scoop out the thread of the backwind part wound around the outer circumference of the bobbin and to search the searcher. Guide the thread to the cutter provided at the base of the piece and cut the thread. In this way, the thread that has been cut in the backwind section sucks in the thread end that has been cut by the suction air from the suction mouth that is close to the outer circumference of the thread, and rotates the thread in the unwinding direction of the thread. While pulling out, the thread end is pulled out.

[0007]

[Problems to be solved by the device]

 In such a searcher, the thread in the backwind portion on the outer circumference of the bobbin is scooped and cut, but the thread end portion may be caught on the searcher at the time of cutting. This hooked yarn end often falls due to contact with the bobbin outer peripheral surface, etc., but it may remain caught on the searcher depending on the winding method of the bobbin outer peripheral surface and the direction of the searcher piece. is there. That is, the bobbin thread varies depending on whether it is S-winding or Z-winding in the opposite direction, and further, depending on whether the rotation direction of the turret is R-rotating right or L-rotating, the thread hits the searcher piece. different. Therefore, due to these circumstances, the thread remains caught on the searcher piece, and the number of thread ends gradually increases. As a result, many yarn ends are accumulated between the searcher piece and the bobbin outer periphery, the tip of the searcher piece does not contact the outer circumference of the pipe thread, the function of the searcher is lost, and the ejection rate of the ejection processing apparatus decreases. There was a flaw.

Therefore, according to the present invention, by scooping off the thread on the outer periphery of the tubular thread and removing the thread waste caught on the searcher piece to be cut, the thread is surely scooped by the searcher, and the thread is squeezed out. The purpose is to improve the output rate of the device.

[0009]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention proposes an automatic winder spouting device for spouting the end of a yarn, in which air is directed toward a searcher piece that squeezes and cuts the yarn by pressing it against the outer circumference of the moving yarn. It is equipped with a nozzle that ejects the yarn, and by doing so, the yarn waste caught on the searcher piece is removed, and the yarn is reliably picked up by the searcher and the yarn is ejected. It is a thing.

[0010]

[Action]

 Since the present invention is configured as described above, the yarn thread conveyed to the automatic winder is accommodated in the accommodation groove provided on the outer circumference of the turret, and while the yarn is moved by the rotation of the turret, the yarn end device performs the yarn end ejection processing. Done. On the way, the searcher piece is pressed against the outer periphery of the moving tubular yarn, and the yarn wound around the outer periphery of the tubular yarn is scooped and cut to form a yarn end. The lint entangled in the searcher piece is blown away by the air supplied from the nozzle, and the entangled lint prevents the searcher piece from scooping up the yarn on the outer circumference of the yarn.
