DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An automatic winder provided with a bobbin conveying device according to the present invention will be described with reference to FIGS.

In this automatic winder, for example, an A-type winding unit 1 in which a plurality of winding units for winding A-type yarns are arranged in parallel, and a plurality of winding units for winding B-type yarns are arranged in parallel. 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, an actual bobbin carry-in path 6 for carrying the actual bobbin supplied from the bobbin processing unit 3 and an empty bobbin for carrying out the empty bobbin discharged from the winding unit after the rewinding is completed. A bobbin unloading path 7 is provided along each winding unit. Further, an A-type actual bobbin circulation path 8 is provided between the A-type winding unit unit 1 and the actual bobbin loading path 6, and a B-type winding unit unit. The B type actual bobbin circulation path 9 is provided between the second bobbin 2 and the actual bobbin carry-in path 6 respectively. Outside the empty bobbin carrying-out path 7, an empty bobbin storing path 10 is provided at the downstream end and the upstream end of the empty bobbin carrying-out path 7 and connected endlessly. The empty bobbin storage path 10 may be in the form of a blind alley without connecting the downstream end to the empty bobbin discharge path 7.

The bobbin processing section 3 includes a type A actual bobbin supply station 11 for inserting a real bobbin of the A thread type into an empty tray by a shooter, and a type B for inserting an actual bobbin of a B type to an empty tray by a shooter. The kind actual bobbin supply station 12, an ejection device 13 that ejects the yarn end of the actual bobbin supplied at any one of the actual bobbin supply stations, and the actual bobbin that failed to be ejected by the ejection device 13 is returned to the ejection device again. A circulation path 14, a conveyance path 15 for feeding an empty bobbin carried out from the empty bobbin discharge path 7 to the circulation path 14, a bobbin extracting device 16 for extracting an empty bobbin sent to the conveyance path 15 from a tray, and an empty bobbin discharge path 7
A trace topper 17 and a kind discriminating sensor 18 provided in front of a branch section from the empty bobbin storage path 10 to the empty bobbin storage path 10, and a transfer path provided at a branch section from the empty bobbin discharge path 7 to the empty bobbin storage path 10 as necessary. Switching lever 1 for switching
9 and a full sensor 20 provided at an upstream position of the transport path 15 for stopping the winding of the unit (stopping the knotting) when the empty bobbin is full in the transport path 15 for a certain period of time. Provided.

Next, referring to FIG.
7. The mutual relationship between the type determination sensor 18 and the switching lever 19 will be described.

An empty bobbin discharge path 7, an empty bobbin storage path 10,
The transport path 15 is an endless conveyor belt 2
1, a conveyor belt 22, a conveyor belt 23, and a guide plate 24 provided at a position substantially above the height of the tray T from the conveying surface of each conveyor belt. Each transport path is defined by an opening in a portion of the guide plate 24 corresponding to the center of the belt.

The kind discriminating sensor 18 is a color sensor for discriminating the color corresponding to the thread kind applied to the base peripheral surface of the tray T, and is not energized during the normal operation of the automatic winder. Electricity is supplied when a lot change of the unit is performed or when the bobbin to be supplied to the actual bobbin supply station of one of the thread types runs out and the unit of the thread type is stopped. Then, at the time of energization, the tray T carried out from the empty bobbin carrying-out path 7 is temporarily stopped by the trace topper 17 and is irradiated with light by the type discriminating sensor 18. Then, the kind discriminating sensor 18 receives the reflected light from the tray T and emits a signal corresponding to the light amount. The color of the tray T is, for example, black for the type A and white for the type B.

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 discriminating sensor 18 is energized. Normally, the switching lever 19 stands by at a position deviating from the empty bobbin unloading path 7 and operates when the signal from the type discriminating sensor 18 is a signal corresponding to a specific thread type, and the transport path is changed to the empty bobbin storage path. It is switched to the 10 side. Which signal from the type discriminating sensor 18 activates the switching lever 19 is selected by switching a switch in the control box 5.

For example, when a lot change is to be performed only on the A-type winding unit 1 or when there are no more actual bobbins to be supplied to the A-type actual bobbin supply station 11, first, the trace topper 17 and the type identification sensor 18 Then, the switching lever 19 is made operable, and then the switch of the control box 5 is set so that the switching lever 19 is activated when the type discriminating sensor 18 emits a signal corresponding to the A type.

In this state, when the tray T moves along the empty bobbin carrying-out path 7, the tray T is temporarily stopped by the trace topper 17, and the type discrimination sensor 18
Depending on the product type When the signal from the type determination sensor 18 is a signal corresponding to the type A, the switching lever 19 is operated to close the empty bobbin carrying-out path 7, and the tray T is directed to the empty bobbin storage path 10. When the signal from the type discriminating sensor 18 is a signal corresponding to the type B, the switching lever 19 does not operate, and the tray T advances straight through the empty bobbin unloading path 7 and enters the transport path 15. In this way, it is possible to prevent only the trays of type A from being sent to the unit. In the above embodiment, the bobbin processing unit 3 removes the empty bobbin from the tray and mounts the actual bobbin on the tray. In addition, the automatic winder and the spinning machine are connected, and the tray is circulated between them. It is also possible to apply the present invention to an apparatus in which an empty bobbin is removed from a tray on the spinning machine side and an actual bobbin is mounted on 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 bobbins to be supplied to the actual bobbin supply station of the specific yarn type, the yarn type of the specific yarn type is lost. The bobbin can be automatically and reliably not sent to the unit.
