Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for taking out the thread end of a bobbin, and in particular, to a device for taking out the thread end of a bobbin, and particularly to a device for taking out the thread end of a bobbin on a conveyor that transfers a bobbin inserted in a tray from a spinning machine to an automatic winder. The bobbin is stopped while moving the conveyor, and at this position the bobbin is rotated on its own axis by the conveyor to release the bunch winding of the bobbin, and the thread end is pulled out and inserted into the top hole of the bobbin. It is related to.

[Prior Art] Generally, a yarn end pulling device as shown in FIG. 7 is known.

As shown in Fig. 7, it has eight stations A to H that share the work of picking out the thread end of the bobbin.
Move bobbin c inserted into tray b to station A.
A conveyor d transports the bobbin c inserted into the tray b from the spinning machine to the tray receiving station A, and an automatic winder transports the bobbin c taken out from the delivery station F. Conveyor e conveying to (not shown)
and is provided. Station B has a cutter device j for releasing and cutting the bunch winding p wound around the lower end of the bobbin, and station C has a bobbin c for winding the yarn released at station B onto the surface of the yarn layer of bobbin c. A friction roller k is provided to rotate the tray b and the tray b integrally. The station D is also provided with a friction roller f that contacts the tray b and rotates it, and a suction mouth g that sucks and draws out the yarn end from the yarn layer of the bobbin. This suction mouth g extends above the station E,
A yarn detection/cutting device h, which is an integrated yarn detection feeler that detects the yarn pulled out by the suction mouth g and a cutter that cuts the yarn to a predetermined length, is connected to the suction mouse by the fixed support member i. It is fixed to station E and is provided above station E. Furthermore, a suction pipe (not shown) for suctioning the cut yarn through the bottom opening o of the tray b and inserting it into the top hole n of the bobbin c is provided below the station E. There is. The station F is provided with a sensor (not shown) for confirming that the thread that has been threaded out is inserted into the top hole n of the bobbin c. A movable guide (not shown) is provided to deliver the bobbin c to a conveyor e that transports it to an automatic winder (not shown), and to transport the bobbin c to a station G if delivery fails. Stations G and H are bypass stations that send bobbins that have failed to be picked out to station A again.

The above-mentioned outlet device thus operates as follows. The bobbin c inserted into the tray b is conveyed from the spinning machine to the tray receiving station A of the rotary disk a by the conveyor d, and then transferred to the station B by the rotary disk a. At station B, bobbin c and tray b are rotated integrally by cutter device j in a direction in which the yarn ends are released, and the released yarn ends are sucked. Therefore, the bunch winding p wound around the lower end of the bobbin c is released, and the suctioned thread is cut within the cutter device j. The bobbin c from which the bunch winding p has been released is wound at a station C by a friction roller k on the surface of the yarn layer of the bobbin c.
Next, at station D, bobbin c is rotated by friction roller f in the direction in which the thread of bobbin c is released integrally with tray b, and at the same time, the thread layer is removed by suction from suction mouth g. The yarn end is sucked in through the suction port l of the suction mouth g. The suction mouth g has a slit m extending from its suction port l to above the station E, and the thread sucked in from the suction port l moves along the slit m. When the bobbin c moves to the station E, the thread enters a thread detection/cutting device h provided above the station E, is detected by the thread detection/cutting device h, and is cut. At the same time,
Since the thread is suctioned from below the tray through the top hole n of the bobbin c by the top hole suction pipe, the cut thread is inserted into the top hole n. In this way, the bobbin c that has finished the unloading operation is supplied from the station F to the automatic winder by the conveyor e. However, the bobbin c whose yarn end was not confirmed to have been inserted into the bobbin top hole n by the sensor at the station F is not delivered from the station F to the conveyor e due to the action of the movable guide, and is not delivered by the rotary plate a. Then, it is transferred to bypass stations G and H, and the extraction operation from station A is performed again.

[Problems to be solved by the invention] As mentioned above, the conventional yarn end pick-up device is formed of a rotary plate having eight stations that share the work of picking out the thread, and the power and power to move the bobbin to each station are , the power to rotate the bobbin to release the bunch winding of the bobbin and the power to rotate the bobbin when suctioning the end of yarn from the bobbin are provided separately, making the unwinding device large and complicated. Along with this, there was the problem that it became expensive.

[Means for Solving the Problems] The present invention consists of a conveyor on which a tray with bobbins inserted is placed and transferred from a spinning machine to an automatic winder, and a conveyor installed at a predetermined position in the middle of this conveyor on the side thereof. A suction mouth having an upwardly extended slit is provided at a predetermined position to engage and stop the transferred tray, and also to tilt the bobbin in cooperation with the suction of the suction mouth to remove the tray. A tray stopping means for bringing only the bottom peripheral edge into contact with the conveyor placement surface, a cutter means for cutting the thread end pulled out by the suction mouth into a predetermined length, and a thread end cut by the cutter means. a top hole suction suction means for suctioning the yarn end from the bottom opening of the tray and inserting it into the bobbin top hole, and a tray release means for releasing the stopping means after the suction means inserts the thread end into the bobbin top hole. It is equipped with the following.

[Operation] With the above configuration, the tray transported to a predetermined position by the conveyor is stopped by the tray stopping means. The suction mouse uses its suction force to tilt the bobbin inserted into the tray in cooperation with the tray stopping means. The tray rotates because only its bottom peripheral edge is brought into contact with the placement surface of the conveyor. Due to this rotation, the suction mouth releases the bunch winding and pulls out the yarn end from the yarn layer of the bobbin. The cutter means cuts the thread drawn upward along the slit into a predetermined length.
The top hole suction suction means inserts the cut thread into the bobbin top hole. The tray release means releases the tray from being stopped by the tray stop means, and restarts tray transport by the conveyor.

[Example] An example of the present invention will be described with reference to the accompanying drawings.

The operation of this embodiment will be described below.

As shown in FIG. 2, the tray guide 5 is located at the height of the bobbin stand 15 of the tray 1 and is provided on the conveyor belt 3 so as to sandwich this. is transferred from the spinning machine along the tray guide 5.
A sensor provided on the tray stopper 6 detects the tray 1 being transferred on the conveyor belt 3, and when the tray 1 reaches above the top hole suction pipe 4, the tray stopper 6 detects the tray 1 as shown in FIG. grips the tray 1 and stops it on the side edge of the moving conveyor belt 3. Next, suction mouse 7
When the bobbin 2 sucks the longitudinal side of the bobbin 2, the bobbin 2 moves the tray 1 while being supported by the tray stopper 6, as shown in FIG.
The suction mouse 7 is tilted integrally with the suction mouse 7.
Then, only the bottom peripheral edge of the tray 1 comes into contact with the conveying surface of the moving conveyor belt 3, and the frictional contact between the conveyor belt 3 and the tray 1 causes the direction in which the bunch winding 18 at the lower end of the bobbin 2 is released. Rotate to . At this time, since the contact point of the tray stopper 6 with the tray 1 is the roller 19, the tray stopper 6 does not interfere with the rotation of the tray 1. As shown in FIGS. 1 and 5, when the bunch winding 18 is released, the yarn end 20 is drawn into the suction mouth 7. As shown in FIG. 1, the suction mouth 7 is provided with a slit 22 extending upward from the suction port 21 of the bobbin 2, and the thread end 20 sucked in from the suction port 21 of the suction mouth 7 is passed through the slit 22. , and comes into contact with the yarn detection/cutting device 11 as shown by the yarn end 23 shown by the chain line in FIGS. 1 and 5. When the yarn detecting feeler of the yarn detecting/cutting device 11 detects the yarn, the suction mouth 7 stops suctioning, the suction pipe 4 for top hole suction starts suctioning, and the bobbin 2 starts suctioning, as shown in FIG. The bobbin head is tilted to the opposite side of the bobbin mouth 7, and the bobbin head is supported by the head push guide 8.
At approximately the same time, the yarn detection/cutting device 11 detects the yarn end 2.

As shown in FIG. 4, the top hole 12 of the bobbin 2 communicates with the bottom opening 13 of the tray 1 via the air passage hole 17 of the tray 1, so as shown in FIG. The cut yarn end 23 is inserted into the top hole 12 of the bobbin 2 by suction from the lower top hole suction pipe 4 . Top hole 1 of thread end 23
When the tray stopper 6 is confirmed to be inserted into the tray 1 by a sensor, the stopper control device 24 is activated to move the tray stopper 6 away from the tray 1. Then, the bobbin 2 and the tray 1 are again transferred to the automatic winder along the tray guide 5 by the conveyor belt 3.

In summary, the bobbin 2 being transferred from the spinning machine to the automatic winder by the conveyor belt 3 is temporarily stopped, and at this position, the bobbin 2 is rotated using the conveyor belt as power to release the bunch winding 18 and the winding is started. Insert the thread end 23 into the top hole 1 of the bobbin 2.
It can be inserted into 2. Therefore, the yarn end can be pulled out using a simple pull-out device whose only power source is the conveyor belt 3.

In this embodiment, an example is shown in which the present invention is applied to a case where the lower end of the bobbin 2 is provided with the bunch winding 18, but the present invention can also be applied to a bobbin having a top bunch with some modifications.

Furthermore, if the conveyor belt 3 is formed into a net shape and the tray is configured to contact the conveyor belt 3 and rotate in one direction, the suction pipe 4 for the top hole suction can be inserted from below the conveyor belt via the conveyor belt. The thread end can be inserted into the top hole 12 of the bobbin 2 by suction. Therefore, in this case, the head push guide 8 and the tray guide 5 are unnecessary.

In this embodiment, a sensor is provided to confirm the insertion of the thread end into the bobbin top hole 12, and then the tray stopper is released. A sufficient time for insertion into the hole 12 may be measured, and the tray stopper may be automatically released when the suction time has elapsed.

Further, in this embodiment, a yarn detection/cutting device 11 is used which integrates a yarn detection feeler for detecting a picked yarn and a cutter means for cutting this yarn into a predetermined length. It is also possible to use a yarn detection feeler and a cutter means.

[Effects of the invention] The invention exhibits the following excellent effects. The rotation of the tray required for unloading the bobbin is done by tilting the bobbin using the suction force of the suction mouth and the tray stopping means, and using the transfer force of the conveyor, so there is no need for power to rotate the bobbin. As a result, a simple and low-cost extraction device can be achieved.
