Abstract
Abstract A bobbin handling system in which bobbin carriers of an overhead conveyor receive various types of bobbins from delivery stations and deliver the bobbins to receiving stations. A control system includes a stationary fluid operated control unit at each of the stations and actuators for the control units on each of the carriers. As an actuator passes a control unit it causes operating fluid to be supplied to the control unit and then closes active fluid bleed ports if its carrier and the station are both in condition to either receive or deliver a particular type of bobbin, whereupon the control unit causes bobbins to be so delivered or received. Finally, the passing actuator causes the operating fluid to be shut off.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
134 words
A system for handling different types of bobbins, comprising, stations, at least one for transferring each of the different types of bobbins fluid operated means controlling the transfer of said bobbins, one for each of said stations, and each said control means including normally inactive sensors for indicating the type of bobbin handled by the station, normally closed fluid supply means, one for each of said control means, and actuable for supplying operating fluid to the associated control means, conveyor means having carriers for said bobbins, said carriers being mounted for movement past said stations, and actuation means, one on each of said carriers, each said actuating means actuating said supply means of a station to supply said operating fluid to the associated control means only while the associated carrier is proximate the station.
Claim 2
Independent Claim
134 words
A system for handling different types of bobbins, comprising, stations, at least one for transferring each of the different types of bobbins fluid operated means controlling the transfer of said bobbins, one for each of said stations, and each said control means including normally inactive sensors for indicating the type of bobbin handled by the station, normally closed fluid supply means, one for each of said control means, and actuable for supplying operating fluid to the associated control means, conveyor means having carriers for said bobbins, said carriers being mounted for movement past said stations, and actuation means, one on each of said carriers, each said actuating means actuating said supply means of a station to supply said operating fluid to the associated control means only while the associated carrier is proximate the station.
Claim 3
Dependent Claim
48 words
A system as set forth in claim 1 in which each said actuating means includes actuator means for operating said sensors to activate said control means only when the type of bobbins and the conditions of the carrier and the station associated with the control means are compatible.
Claim 4
Dependent Claim
63 words
A system as set forth in claim 2 in which at least one of said actuator means is adjustable to correspond with the condition of the associated carrier to transfer bobbins, and said control means inCludes means for adjusting said adjustable means responsive to a change in said condition when particular ones of the associated sensors are operated to activate to control means.
Claim 5
Dependent Claim
93 words
A system as set forth in claim 3 in which the adjustable actuator means includes a member having a plurality of actuators, one for closing each of particular ones of said sensors, when the particular actuator is in an actuating position, means mounting said member for movement to position any one of said actuators in said actuating position, and said control means includes means operable for moving said member to position another of said actuators in said actuating position only when particular ones of said sensors are closed to activate said control means.
Claim 6
Dependent Claim
29 words
A system as set forth in claim 4 in which the mounting means rotatably mounts said member, and said actuators are fingers extending generally radially outwardly from said member.
Claim 7
Dependent Claim
38 words
A system as set forth in claim 5 in which the moving means comprises an abutment, and means mounting said abutment for movement into the path of travel of said adjustable actuator when the control means is activated.
Claim 8
Dependent Claim
44 words
A system as set forth in claim 6 in which at least one of said actuators is positioned operatively stationary in a selected position on said actuating means, and said actuating means having means for mounting the operatively stationary actuator in various selected positions.
Claim 9
Dependent Claim
105 words
A system as set forth in claim 7 in which said sensors comprise normally open bleed means for said operating fluid, said control means provides means including said bleed means for cleaning at least a portion of said control means and said actuating means when said fluid supply means is actuated, said fluid supply means includes first means operably for so supplying said fluid to said control means and second means operable for stopping the supply of said fluid to said control means, and said actuating means operates said first means and then said second means as the associated carrier is passing said control means.
Claim 10
Dependent Claim
44 words
A system as set forth in claim 2 in which at least one of said actuators is positioned operatively stationary in a selected position on said actuating means, and said actuating means having means for mounting the operatively stationary actuator in various selected positions.
Claim 11
Dependent Claim
52 words
A system as set forth in claim 1 in which said sensors comprise normally open bleed means for said operating fluid, and said control means provides means including said bleed means for cleaning at least a portion of said control means and said actuating means when said fluid supply means is actuated.
Claim 12
Dependent Claim
63 words
A system as set forth in claim 1 in which said fluid supply means includes first means operable for so supplying fluid to said control means and second means operable for stopping the supply of said fluid to said control means, and said actuating means operates said first means and then said second means as the associated carrier is passing said control means.
