BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bobbin supplying device for separating a plurality of fine spinning bobbins contained therein one by one.

[0002]

2. Description of the Related Art Conventionally, in the case where bulk-spun spinning bobbins are supplied to each unit of an automatic winder, bobbins continuously fed from an outlet of a vibration type parts feeder are separated one by one by a supply conveyor. It is sent to the Amajiri discrimination section,
While pushing the bobbin laterally with pushers along the regulation guides that regulate the levels at both ends of the bobbin,
The top end of the bobbin is determined by the top end discriminating feeler provided on the above-mentioned feeding path, and based on the result, the bobbin is dropped into the chute from the bottom side, and on the tray circulating between the units of the automatic winder. And the bobbin was inserted into the tray and conveyed to each unit of the automatic winder.

In such a bobbin supplying device, the supply conveyor requires a certain conveying section to separate and supply the bobbins continuously fed from the parts feeder one by one. There was a problem in that the size was increased and the responsiveness to the bobbin request was prompt. Therefore, conventionally, the bobbin is stopped at each of the outlet of the parts feeder, that is, the introduction section of the supply conveyor and the delivery section of the supply conveyor, and the separate supply is performed in two stages to improve the responsiveness at the delivery section. However, the size of the device has become larger.

In addition, when the top end discriminating portion discriminates the top end while pushing the bobbin with the pusher, the bobbin is rattled or lifted up from the regulation guide due to a reaction when feeding from the supply conveyor or when pushing the bobbin. Then, an error will occur in the discrimination result by the Tenjiri discrimination feeler. Therefore, in the past, a push guide was used to lengthen the run-up section of the regulation guide that pushes the bobbin to the top of the tail, and the rattling of the bobbin is set in that section to prevent errors in the top-end detection. The longer the size, the larger the device,
Moreover, there is a problem that the processing time becomes long.

[0005]

In view of the above-mentioned problems of the prior art, the present invention aims to improve the processing speed, downsize the apparatus, and reduce the cost while securing the stability of the supply operation. It is an object of the present invention to provide a bobbin supplying device that can be realized.

[0006]

A bobbin individualizing roller for individualizing and delivering a bobbin is provided at an exit of a parts feeder for separating and delivering a large number of accommodated bobbins. Also,
A sensor for detecting the bobbin locked by the bobbin individualizing roller that is stopped at the exit of the parts feeder and a sensor for detecting the bobbin sent from the bobbin individualizing roller at that position are provided. Further, a member for controlling the posture of the bobbin is provided so that both ends of the bobbin come into close contact with the guide for regulating the level of the bobbin pushed by the top edge determining portion.

[0007]

When the bobbin on the delivery side of the individualizing roller of the bobbin, that is, on the introduction side of the tail edge determining section is pushed out to the tail edge determining section, the bobbin individualizing roller rotates and locks on the roller. The bobbin individualizing roller is stopped by supplying the one bobbin that has been used to the side of the top of the top of the top of the tail discriminating unit, and detecting the bobbin by the sensor. At the same time, the parts feeder is activated, the next bobbin is locked by the bobbin individualizing roller that is stopped, and the parts feeder is stopped by the sensor detecting the bobbin.

On the other hand, in the top edge determination section, the attitude control member performs the top edge determination with both ends of the bobbin being pushed in close contact with the guides for regulating the level of the bobbin, and based on the determination result. The bobbin is supplied from the bottom side when the bobbin is requested.
