Description

[Detailed description of the invention] 〓Field of industrial application〓 The present invention removes waste threads from inside the center hole of the empty bobbin and on the tray when the empty bobbin is rewound in a winder and placed on the tray for conveyance. Regarding equipment.

〓Conventional technology〓 A spinning winder that has a bobbin conveyance path between the spinning machine and the winder for loading and transporting bobbins on a tray is designed to balance the yarn throughput between the spinning machine and the winder. In addition, the waste yarn remaining in the center hole of the empty bobbin is automatically disposed of. As a conventional waste thread removal device, for example,
As shown in No. 257878, an empty bobbin placed on a tray and sent back through the bobbin transport path is temporarily pulled up from the tray, and the center hole of the empty bobbin is inserted from the bottom of the pulled up empty bobbin. Some types have a structure that blows compressed air inward to discharge waste threads remaining on the empty bobbin.

〓Problems to be solved by the invention〓 The structure in which compressed air is sprayed from below the empty bobbin requires a mechanism to pull the empty bobbin out of the tray, and although it is possible to remove waste yarn from the empty bobbin, The waste threads attached to the tray could not be removed.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a waste thread removing device that can process waste threads while an empty bobbin is placed in a tray, and can also remove waste threads on the tray.

〓Means for solving the problem〓 As a means for simultaneously removing the waste threads remaining in the center hole of the empty bobbin and the waste threads remaining on the tray, the waste threads are removed by suction with air. To this end, a cylindrical body is provided on the top of the empty bobbin that is inserted into a tray and transported, and is moved back and forth like a piston by a motor, etc., and the hollow part of this cylindrical body is connected to an air intake device such as a blower. The top of the empty bobbin was covered with the hollow part of the cylindrical body, so that the waste yarn inside the center hole of the empty bobbin and on the tray was sucked into the inside of the cylindrical body.

<Operation> When the empty bobbin inserted in the tray reaches a predetermined position on the conveyance path, the cylindrical body advances toward the top of the empty bobbin, and the cylindrical body covers the top of the empty bobbin. Therefore, when the suction force of the suction device reaches inside the hollow part of the cylindrical body, it suctions the inside of the center hole of the empty bobbin, and the empty bobbin is lifted by the suction force, and the peg supporting the empty bobbin on the tray and the empty bobbin A gap is created between the lower end and the center hole of the empty bobbin, and the waste threads caught on the pegs, etc. and remaining on the tray are sucked through the hollow part of the cylindrical body toward the suction device, and the waste threads are removed. be done.

〓Example〓 The device of the present invention places spinning bobbins and empty bobbins 3 on tray 1 between an automatic winder and a ring spinning machine.
A cylindrical body that covers the top of the empty bobbin 3 and is installed in the path of the conveyance path of the empty bobbin 3 sent out from the automatic winder of a spinning winder having a bobbin conveyance path for inserting the bobbin into an upright peg 2 and transferring the bobbin vertically. 4, a drive mechanism 5 that moves the cylindrical body 4 up and down, and an intake device such as a fan (not shown).

The cylindrical body 4 has a head 7 connected and fixed to the lower end portion of a cylindrical main body 6, and is fitted into the cylindrical body of a fixed cylinder 9 provided in the casing 8 so as to be movable up and down. The upper open end of the fixed cylinder 9 is closed by a support plate, and a guide groove 25 is provided in the side wall portion from below. The drive mechanism 5 that moves the cylindrical body 4 up and down includes a motor 10, a transmission shaft 11,
A reciprocating slider crank mechanism is adopted in which the rotational motion of the motor 10 is transmitted to the swinging arm 12 by a transmission shaft 11, and the swinging arm 12 uses a support shaft 13 as a fulcrum. Perform rocking motion. The swinging motion of the swinging arm 12 is caused by a disc-shaped bearing 1 attached to a pin 14 attached to the cylindrical main body 6 of the cylindrical body 4.
5 is provided, and this bearing 15 is placed on the swinging arm 12 to transmit the signal to the cylindrical body 4. Further, this bearing 15 is inserted into the guide groove 25 of the fixed cylinder 9 so as to be guided therein. 16,
16 is a coil spring, one end of which is connected to the cylindrical body 4;
and the other end is fixed to the casing 8, so that the pin 14 is always biased in a downward direction. A sector-shaped iron piece 18 is pivotally supported on the rotating shaft 17 of the motor 10, and a proximity switch 19 is provided within the rotation locus of this iron piece 18. is made to wait above.

A pair of swinging arms 12 are provided so as to sandwich the cylindrical body 4 between them, and the swinging ends of both arms are connected by a connecting member 20, and the connecting member 20 and the transmission shaft 11 are connected to each other by a ball-shaped universal joint. They are connected via 21.

A vent hole 22 is opened in the fixed cylinder 9,
This vent 22 is connected with an intake pipe 23 that is connected to an intake device such as a fan (not shown). The opening position of this vent 22 is closed by the wall surface of the cylinder main body 6 when the cylindrical body 4 is in the raised position, and when the cylindrical body 4 is lowered, the vent 22 is opened and the cylindrical body 4 is closed. The position is set such that the suction force of the air intake device is applied to the hollow portion 24 of the air intake device.

Next, the operation of the device of the present invention will be explained in detail based on the above embodiment.

Empty bobbins 3 processed by an automatic winder (not shown) are inserted into pegs 2 of a tray 1, and transported along a conveyance path to a ring spinning machine (not shown). When the empty bobbin 3 reaches a predetermined position, a stop mechanism (not shown) prevents the tray 1 from advancing. Then, the motor 10 operates to crank the transmission shaft 11 and move the swinging arm 12 to the first position with the support shaft 13 as the fulcrum.
The cylindrical body 4 swings counterclockwise in the figure, and the pin 1
4 is lowered by a coil spring 16 which is applied with a force to pull it down in the figure. This downward movement of the cylindrical body 4 causes the head 7 to cover the top of the empty bobbin 3. At this time, the vent 22 is opened as shown in FIG.
2, the fixed cylinder 9 and the hollow part 24 of the cylindrical body 4. As the air in the hollow part 24 of the cylindrical body 4 is sucked upward in FIG. At the same time, the empty bobbin 3 is slightly lifted by the suction force, and the waste threads that were caught on the tray 1 by the empty bobbin 3 are also suctioned and removed. The swinging arm 1 is rotated by the rotation of the motor 10.
2 and 12 swing clockwise in FIG. 1, the bearing 15 is pushed up by the swinging arm 12 in the same drawing, the cylindrical body 4 rises, and the top of the empty bobbin 3 is released. . At the same time, the vent 22 is connected to the cylinder main body 6.
It is blocked by the wall of the wall, and air intake is blocked. Swing arm 12
The movement of one stroke is completed when the iron piece 18 connects the proximity switch 19, and remains in a standby state until the next empty bobbin arrives.

〓Effects of the invention〓 The device of the present invention can process empty bobbins that are inserted into a tray and transported as they are without mechanically moving them, and with a simple configuration, it can reliably remove waste threads remaining in the center hole. Can be removed. Moreover, by configuring the apparatus so that the waste threads in the center hole of the empty bobbin are removed by suction, it is also possible to simultaneously remove the waste threads on the tray by suction.
