Description

[Detailed Description of the Invention] [Field of Industrial Application] When transporting and supplying spinning machine spindle yarn in the spinning process using a reel tray such as an automatic rewinding machine, it is necessary to pull out the opening of the yarn in advance and turn it into a tube. The yarn is introduced and held in the top hole of the bobbin, and when the bobbin is inserted into the tray, one yarn is pulled out and supported on a holding plate, and the cut yarn is inserted into the top hole of the bobbin. The device is constructed so that the holding plate is retracted and the stub holding tube is inserted into the conveyance tray.

[Conventional technology]

When feeding the yarn from the spinning machine to the automatic rewinding machine,
It is well known that the thread of the thread is pulled out in advance and then introduced into the top hole of the thread bobbin and held there (
For example, Japanese Patent Publication No. 40-21490). It is also known to feed the yarn to an automatic rewinding machine by inserting each yarn into a tray formed with pegs and actively moving the tray to feed the yarn. By the way, in order to pull out the thread from the tube thread inserted in the tray, it is necessary to provide a device for pulling out the thread in Inuyama Rina and a device for introducing the drawing thread into the top hole in the tray transfer path. They have developed and proposed a method in which the thread is pulled out in advance before the thread is inserted into the tray, and the drawn thread is introduced into the top hole of the bobbin at the same time as the thread is inserted into the tray.

The paper also proposes means for restricting the pulling out of the thread from the tube thread inserted into the tray. By the way, when carrying out such a method, it is necessary to have a ventilation hole in the tube transport tray to pass the suction air flow for introducing the thread, and also to install a suction device on the tray to connect the tube and thread bones to the tray that is stopped at the standby position. It is necessary to install it on the transfer route.

Therefore, it is pointed out that a conventional tray without ventilation holes cannot be used.

[Problem that the invention seeks to solve]

Therefore, in the present invention, the opening thread is pulled out in advance before the pipe thread is inserted into the pipe transport tray.

In the means for inserting the pipe yarn into the tray, the yarn is inserted into the top hole and then inserted into the tray, so that the conventionally used tray with no ventilation holes can be used as is, and it can be done with a simple construction means. It is configured in such a way that it can be obtained.

[Means for solving problems]

That is, in the present invention, when a yarn from which one yarn has been pulled out is dropped into a conveyance tray and inserted, the dropped yarn is temporarily supported by a movably provided holding plate, and the yarn of the yarn on the holding plate is temporarily supported. A suction port is provided in the part corresponding to the bottom hole of the bobbin, and the suction port is communicated with a separately provided suction nozzle. This structure is such that the pipe thread with the stent introduced therein is inserted into the conveyance tray which is on standby after being moved back.

[Function and Examples]

The present invention will be described in detail below based on the drawings, but the drawings show an example of a specific implementation of the present invention, and the present invention is not limited to the illustrated example. It is possible to carry out the same implementation even if the design is changed or a part of the design is changed. FIG. 1 (side view) shows a latch introduction and conveyance device to which the present invention is applied, and the device 2 includes a frame 2@,
2BlI, and a yarn retention hopper 3 is provided on the upper side thereof. It should be noted that the yarn may be fed to this hopper 3 by an appropriate means, or the yarn storage container may be replaced.
Any conventionally known device can be freely selected and provided as long as it allows the retained pipe threads to be paid out individually and sequentially. The pipe thread unwound from the hopper 3 is sent to a holding and rotating device 4, where it is gripped and rotated. , is sucked and held by this nozzle device 5.

After the thread has been drawn out, the thread is released from the holding/rotating device 4 and dropped through the chute 6. A guide tube 9 that can be opened and closed is provided at the F lowering position, and a lower part of the guide tube 9 A holding plate 14, which constitutes the main part of the present invention, is movably provided.

Insert 1g of thread into the top hole of the bobbin, and insert the holding plate 1.
The holding plate 14 is rotated and retracted to drop and insert the pipe yarn into which the stub is introduced and held on the holding plate 14 into the waiting tray 12. Reference numeral 8 denotes a regulating plate for regulating the unwinding of the lead-out yarn of the drop-in tube yarn and detecting the presence of the drop-in tube yarn, and is always urged and held so as to be in contact with the input tube yarn. In addition, at this time of feeding, the lead yarn 5 is suctioned and held by the nozzle device 5, and is introduced into a cutting device 7 which is open and provided in the path of movement of the lead yarn. The cutting operation is performed after being supported by the holding plate 14.

On the other hand, the tray 12 is made of a tray conventionally known for conveying the tube yarn, and has a base portion having a diameter larger than the outer diameter of the winding of the tube yarn to be inserted, and a peg 12a for inserting the tube yarn in the center thereof. Use what is provided. Although the plan view shows the base portion having a circular base portion, the four corners may be formed into a hexagonal polygon. On the other hand, the transport path 10 for the tray 12 is formed by a frame-shaped guide rail connected in a loop shape to the lower side of the thread introducing and transporting device 2.

A tray 12 is moved by a round belt 11 arranged within the rail. Further, as shown in FIG. 6, this conveyance path 10 serves as a bypass path 10a within the apparatus 2, and a tube insertion portion is formed in the bypass path 10a. Note that this bypass path 10a forms a sliding bottom surface for tray movement.
The tray 12 is moved by swinging the tray feed arm 13 in the direction of the arrow. Figure 1 shows the arm 13 swinging to the retracting side, and the swinging movement moves the empty tray one by one.
They are fed into the bypass path 10a one by one.

On the other hand, the pipe yarn receiving, supporting and holding plate 14 provided in the second thread introducing and conveying device is shown in FIGS. 2 and 3 (cross-sectional view in the direction of the arrow along cutting lines ■-■ and lll-1 in FIG. 1). As shown in FIG. 2, it is rotatably provided on the pivot shaft 15b of the pivot bearing bracket 15 of the guide tube 9, and an operating rod 19 is connected thereto. As shown in FIG. 3, the operating rod 19 is connected to the tip of a lever 20, and the lever 20 is swung by a cam 21 provided on the operating rotation shaft.
