Description

Description: TECHNICAL FIELD The present invention relates to a bobbin yarn end ejection device, and more particularly to a bobbin yarn that can eject the yarn end on a bobbin transport path from a spinning machine to a winder. The present invention relates to an end lead-out device.

[Prior Art] Generally, an actual bobbin produced by a spinning machine in a spinning process is sequentially supplied to a winder in a winding process in order to rewind the yarn. In this way, when supplying the finely spun bobbin to the winder, it is common practice to release the bunch winding formed at the upper end of the bobbin to prevent the looseness of the bobbin, and to let the end of the yarn come out. Therefore, conventionally, a device for releasing the bunch winding of the bobbin and ejecting the yarn end is provided on the side of the winder.

[Problems to be Solved by the Invention] By the way, this type of yarn end leading device has the following problems.

The yarn end leading-out device installed on the side of the winder has a problem that it is a relatively large-scaled device, has a complicated structure, and requires a dedicated space and is expensive.

In view of the above-mentioned problems, an object of the present invention is to provide a bobbin yarn end lead-out device that simplifies the device and can efficiently lead out the yarn end.

[Means for Solving the Problems] In order to solve the problems in the prior art, the present invention has a gripping part for gripping the head of an actual bobbin transferred on a conveying path on the spinning machine side. Moving means for inserting the bobbin into the tray located on the winder side conveying path from the side conveying path, and the bobbin for releasing the bunch winding formed on the upper end of the bobbin by raising the gripping part. And a suction mechanism for sucking the released yarn end into the bobbin.

[Operation] As described above, the moving means for inserting the actual bobbin from the transport path on the spinning machine side into the tray located on the transport path on the winder side has the grip portion for gripping the head of the bobbin. is doing. The lower end of the bobbin located on the tray is gripped by the clamp mechanism, and the gripping part is used to raise the bobbin to release the bunch winding formed on the upper end of the bobbin. The released yarn end is sucked into the bobbin by the suction means and discharged. In this way, the bobbin is one in which the yarn end is ejected and transferred in the conveying process from the spinning machine to the winder.

A swivel clamp 38 is provided for gripping the lower end of the. Clamp revolving means 39 formed of, for example, a hydraulic cylinder for revolving this is connected to the revolving clamp 38, and a clamp mechanism 40 is formed together with the fixed clamp 37. Further, in the vicinity of the tray standby portion 33, an extrusion clamp 41 for facing the starting end portion of the winder side conveyor 5 and pushing out the bobbin 1 together with the tray 6 is provided. This extrusion clamp 4
Reference numeral 1 is connected to an extrusion drive means 42 formed by, for example, a hydraulic cylinder.

Next, the operation of the above embodiment will be described.

The actual bobbin 1 produced by the spinning machine is inserted into the peg 3 of the spinning machine side conveyor 4 and transferred. In order to grip the head of the bobbin 1 waiting at the end of the spinning machine side conveyor 4, the swivel arm 18 is swung by the swivel drive means 20 to position the grip 23 on the head of the bobbin 1.
The lifting drive means 15 lowers the lifting body 14 to insert the head into the grip portion 23. Next, air is supplied from the air supply passage 27 into the hollow chamber 26 of the grip portion 23 to inflate the rubber member 43 and grip the head of the bobbin 1. Then, the elevating / lowering drive means 15 raises the elevating / lowering body 14 to remove the bobbin 1 from the peg 3, and the revolving drive means 20 revolves the revolving arm 18 to wait the bobbin 1 on the tray standby portion 33. Position it on top. The tray 6 is transferred on the standby tray supply conveyor 7, pushed by the turning clamp 38 turned by the clamp turning means 39, and moved to the tray waiting section 33 in advance.

Next, the lifting / lowering body 15 is lowered by the lifting / lowering drive means 15 to insert the bobbin 1 into the tray 6 standing by in the tray waiting section 33. Then, the clamp swivel means 39 swivels the swivel clamp 38 to grip the lower end of the bobbin 1 together with the fixed clamp 37. After that, the elevating and lowering body 14 is elevated by the elevating and lowering drive means 15 to raise the grip portion 23, thereby releasing the bunch winding 44 formed on the upper end portion of the bobbin 1. This is the rubber member 4
Since the friction portion 29 having a corrugated cross-section is formed on the inner peripheral surface of the yarn 3, the yarn end is easily caught by the friction portion 29.
Immediately thereafter, the inside of the suction passage 28 of the grip portion 23 is sucked by a suction device and the released yarn end is sucked upward. Next, the swivel cutter 31 provided at the lower end of the grip portion 23 is swung by the drive device 30 to cut the excess yarn end. Then, while weakening the suction of the yarn by the suction passage 28,
The inside of the bobbin 1 is sucked by the suction means 35 formed in the tray standby portion 33 immediately below the tray 6, and the yarn end is sucked into the inside thereof as shown in FIG. After that, the swivel clamp 38 of the clamp mechanism 40 is removed from the lower end of the bobbin 1 by the clamp swivel means 39, and the push-out driving means 42 advances the push-out clamp 41 to move the bobbin 1 on the winder side, which has completed the yarn end ejection. The winder side conveyor 5 provided in the transport passage 2 is pushed onto the starting end portion and delivered.

As described above, the yarn end of the actual bobbin 1 produced by the spinning machine is efficiently laid out during the delivery work from the transporting path 2 on the spinning machine side to the transporting path 2 on the winder side.

[Effects of the Invention] In short, according to the present invention, the head of the bobbin provided in the moving means for inserting the bobbin from the transport path on the spinning machine side to the tray located on the transport path on the winder side is gripped. Since the bunch winding formed on the upper end of the bobbin is released by using the gripping portion for holding the bobbin, the bobbin transfer operation and the bunch winding release operation can be performed at the same time, and the released yarn end is sucked by the suction means. Since it is sucked into the bobbin and fed out, the time for tapping can be omitted, and it is not necessary to provide a dedicated space for installing the yarn end tapping device on the side of the winder. The whole can be made compact.
