Abstract

PURPOSE:To prevent a bobbin for a target variety of thread from being fed to a unit part in the case of a lot change or the like by connecting an empty bobbin storing path, in which a bobbin for the specific variety of thread can be scored by request, to an empty bobbin convey-out path of an automatic winder. CONSTITUTION:When a lot change is carried out only in an A variety winding unit part 1, or when an actual bobbin to be supplied to an A variety actual bobbin supply station 11 is emptied, a tray moving in an empty bobbin carry-out path 7 is stopped once by a tray stopper 17. When a signal emitted from a variety discriminating sensor 18 is the signal corresponding to the A variety, a switching lever 19 is actuated, so that the empty bobbin carry-out path 7 is closed, and the tray is diverted to an empty bobbin storing path 10. On the other hand, when a signal emitted from the variety discriminating sensor 18 is the signal corresponding to the B variety, the switching lever 19 is not actuated, so that the tray goes straight ahead in the empty bobbin carry-out path 7 and enters a conveying path 15.

B type winding unit 2, a bobbin processing unit 3 provided adjacent to the A type winding unit 1, a blower box 4 and a control box 5 provided adjacent to the B type unit 2. It is composed of

On both sides of the unit section, an actual bobbin carry-in path 6 for carrying in the actual bobbin supplied from the bobbin processing section 3, and an empty bobbin for carrying out the empty bobbin which has been rewound and discharged from the winding unit section. A bobbin carry-out path 7 is provided along each winding unit, and an A-kind actual bobbin circulation path 8 and a B-kind winding unit section are provided between the A-kind winding unit 1 and the actual bobbin carry-in path 6. B type real bobbin circulation paths 9 are respectively provided between the 2 and the real bobbin carry-in path 6. Further, outside the empty bobbin carry-out path 7, empty bobbin storage paths 10 connected endlessly are provided at the downstream end and the upstream end of the empty bobbin carry-out path 7. The empty bobbin storage path 10 may have a dead end shape without connecting the downstream end to the empty bobbin carry-out path 7.

In the bobbin processing section 3, a real bobbin supplying station 11 of A type for inserting an actual bobbin of A yarn type into an empty tray by a shooter and a B for inserting an actual bobbin of B type of yarn in an empty tray by a shooter. Product type Real bobbin supply station 12, Retrieval device 13 for retrieving the yarn end of the real bobbin supplied by any one of the requisite bobbin supply stations, and the real bobbin that failed in the retrieving by the retrieving device 13. Circulation path 14, carrier path 15 for sending empty bobbin carried out from empty bobbin carry-out path 7 to circulation path 14, bobbin removing device 16 for removing empty bobbin sent to carrier path 15 from tray, and empty bobbin carry-out path 7
From the empty bobbin storage path 10 to the trace topper 17 and the product classification sensor 18, and the empty bobbin unloading path 7 to the empty bobbin storage path 10 and, if necessary, the transfer path. Switching lever 1 for switching
9 and a full sensor 20 provided at the upstream position of the transport path 15 for stopping the winding of the unit section (knotting stop) when the empty bobbin is full in the transport path 15 and is on for a certain period of time. It is equipped.

Next, referring to FIG. 2, the trace topper 1
7. The mutual relationship between the product type discrimination sensor 18 and the switching lever 19 will be described.

Empty bobbin carry-out path 7, empty bobbin storage path 10,
The transport paths 15 are endless conveyor belts 2 respectively.
1, a conveyor belt 22, a conveyor belt 23, and a guide plate 24 provided above the conveying surface of each conveyor belt by a distance substantially corresponding to the height of the tray T. Each transport path is defined by the opening of the portion of the guide plate 24 corresponding to the center of the belt.

The type discrimination sensor 18 is a color sensor for discriminating the color corresponding to the yarn type provided on the peripheral surface of the base of the tray T, and is not energized during the normal operation of the automatic winder. Power is supplied when changing the lot of the unit part or when stopping the unit part of one yarn type because there is no bobbin to be supplied to the actual bobbin supplying station of the yarn type. Then, at the time of energization, the tray T carried out from the empty bobbin carry-out path 7 is temporarily stopped by the trace topper 17 and is irradiated with light by the product type discrimination sensor 18. Then, the product type discrimination sensor 18 receives the reflected light from the tray T and emits a signal corresponding to the amount of light. The color of the tray T is black for A type and white for B type, for example.

The switching lever 19 is fixed to the output shaft 26 of the rotary solenoid 25, and the rotary solenoid 25 also becomes operable when the type discrimination sensor 18 is energized. Normally, the switching lever 19 is on standby at a position away from the empty bobbin carry-out path 7, and operates when the signal generated by the product type identification sensor 18 is a signal corresponding to a specific yarn type, and the transport path is empty bobbin storage path. Switched to 10 side. Further, which signal from the product type discrimination sensor 18 activates the switching lever 19 is selected by switching the switch in the control box 5.

For example, when an attempt is made to change the lot only for the A-kind winding unit 1, or when there are no more actual bobbins to be supplied to the A-kind actual bobbin supply station 11, first, the trace topper 17 and the kind discrimination sensor 18 are provided. Then, the switch lever 19 is set to the operable state, and then the switch of the control box 5 is set so that the switch lever 19 is activated when the product type discrimination sensor 18 outputs a signal corresponding to the product A.

In this state, when the tray T moves along the empty bobbin carry-out path 7, the tray T is temporarily stopped by the trace topper 17, and the type discrimination sensor 18
The discrimination of the breed is received. When the signal generated by the product type discrimination sensor 18 is a signal corresponding to the product A, the switching lever 19 is actuated to close the empty bobbin carry-out path 7, and the tray T is directed to the empty bobbin storage path 10. Further, when the signal generated by the product type discrimination sensor 18 is a signal corresponding to the product type B, the switching lever 19 does not operate, and the tray T goes straight on the empty bobbin carry-out path 7 and enters the transport path 15. In this way, it is possible to prevent only the A-type trays from being sent to the unit section. In the above embodiment, the bobbin processing unit 3 extracts the empty bobbin from the tray and mounts the actual bobbin on the tray. In addition to this, the automatic winder and the spinning frame are connected and the tray is circulated between them. It is also possible to remove the empty bobbin from the tray on the spinning machine side and apply the actual bobbin to the tray.

[0017]

Since the present invention is configured as described above, it has the following effects.

That is, when an attempt is made to change the lot of the winding unit of the specific yarn type in the automatic winder, or when there is no more actual bobbin to be supplied to the actual bobbin supplying station of the specific yarn type, It is possible to prevent the bobbin from being automatically and reliably sent to the unit section.
