Abstract
Abstract A system for automatically handling bobbins during processing of the bobbins. Various type of bobbins to be processed are stored in a supply area such as a spinning room where each type is separated into units of predetermined quantity. The units are automatically delivered by means of loading hoppers to suspended containers of a conveyor system for transport to bobbin processing apparatus. Following processing, the bobbins pass to another hopper and are returned to the containers and removed from the processing area to the supply area for additional processing such as stripping off residual yarn, sorting and refilling with yarn. A control system operates the handling system by discriminating between the conveyor containers each of which is designated for handling but one type of bobbin, and determining the condition of each container, whether it is empty or carrying bobbins and if it is carrying bobbins whether the bobbins are processed or are to be processed, and whether or not the hoppers are prepared to deliver the bobbins and the processing apparatus ready to receive a unit of bobbins.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
270 words
A bobbin handling system comprising a first bobbin handling area, a second bobbin handling area, bobbin carrying means, first bobbin delivery means in said first bobbin handling area for delivery of filled bobbins to said bobbin carrying means, first bobbin receiving means in said first bobbin handling area for receiving empty bobbins from said bobbin carrying means, second bobbin receiving means in said second bobbin handling area for receiving said filled bobbins from said bobbin carrying means, means in said second bobbin handling area for receiving the filled bobbins from the second bobbin receiving means and unwinding the filled bobbins to substantially empty the bobbins, second bobbin delivery means in said second bobbin handling area for receiving the empty bobbins from the unwinding means and delivering the empty bobbins to said bobbin carrying means, said bobbin carrying means comprising means for conveying the filled and empty bobbins back and forth between the first and second bobbin handling areas and including a plurality of common bobbin carriers for carrying the filled and empty bobbins, and control means comprising indicating means and responsive means, said indicating means indicating whether each said bobbin carrier is in condition to receive filled bobbins from said first area or empty bobbins from said second area, or to deliver filled bobbins to said second area or empty bobbins to said first area, and said responsive means being responsive to the indicating means for controlling interaction of each said bobbin carrier with an appropriate one of the first or second bobbin delivery means or first or second bobbin receiving means, to deliver or receive filled or empty bobbins.
Claim 2
Dependent Claim
270 words
A bobbin handling system comprising a first bobbin handling area, a second bobbin handling area, bobbin carrying means, first bobbin delivery means in said first bobbin handling area for delivery of filled bobbins to said bobbin carrying means, first bobbin receiving means in said first bobbin handling area for receiving empty bobbins from said bobbin carrying means, second bobbin receiving means in said second bobbin handling area for receiving said filled bobbins from said bobbin carrying means, means in said second bobbin handling area for receiving the filled bobbins from the second bobbin receiving means and unwinding the filled bobbins to substantially empty the bobbins, second bobbin delivery means in said second bobbin handling area for receiving the empty bobbins from the unwinding means and delivering the empty bobbins to said bobbin carrying means, said bobbin carrying means comprising means for conveying the filled and empty bobbins back and forth between the first and second bobbin handling areas and including a plurality of common bobbin carriers for carrying the filled and empty bobbins, and control means comprising indicating means and responsive means, said indicating means indicating whether each said bobbin carrier is in condition to receive filled bobbins from said first area or empty bobbins from said second area, or to deliver filled bobbins to said second area or empty bobbins to said first area, and said responsive means being responsive to the indicating means for controlling interaction of each said bobbin carrier with an appropriate one of the first or second bobbin delivery means or first or second bobbin receiving means, to deliver or receive filled or empty bobbins.
Claim 3
Dependent Claim
68 words
A system as set forth in claim 1 in which said indicating means indicates the condition of the bobbin carriers by providing a first bobbin carrier condition signal indicating when a bobbin carrier is empty of bobbins, a second bobbin carrier condition signal indicating when a bobbin carrier is carrying filled bobbins, and a third bobbin carrier condition signal indicating when a bobbin carrier is carrying empty bobbins.
Claim 4
Dependent Claim
103 words
A system as set forth in claim 1 in which the first bobbin delivery means includes a plurality of delivery stations, at least one for each of a plurality of types of filled bobbins, for discharging the filled bobbins delivered theReby, one of said bobbin carriers being provided for each of said delivery stations for receiving the filled bobbins therefrom, and said second bobbin receiving means includes a plurality of bobbin receiving stations, one for each of said types of filled bobbins, for receiving the bobbins from the bobbin carrier carrying the type of filled bobbins handled by the particular bobbin receiving station.
Claim 5
Dependent Claim
45 words
A system as set forth in claim 3 in which said control means provides bobbin carrier identification signals indicating the type of bobbins handled by each of said bobbin carriers, and station identification signals indicating the type of bobbins handled by each of said stations.
Claim 6
Dependent Claim
105 words
A system as set forth in claim 3 in which said control means provides a bobbin carrier identification signals indicating the type of bobbins handled by each of said bobbin carriers, and station identification signals indicating the type of bobbins handled by each of said stations, and said indicating means indicates the condition of the bobbin carriers by providing a first bobbin carrier condition signal indicating when a bobbin carrier is empty of bobbins, a second bobbin carrier condition signal indicating when a bobbin carrier is carrying filled bobbins, and a third bobbin carrier condition signal indicating when a bobbin carrier is carrying empty bobbins.
Claim 7
Dependent Claim
61 words
