Abstract
Abstract Automatic cop feeder used in combination with bottomless type cop containers containing cops in prescribedly defined multiple columns wherein cops are delivered from said container into a cop shooting tunnel intermittently from column to column with a help by a feeler disposed to the tunnel and thusly delivered cops are transported one by one towards next operational station such as a rewinding part from the shooting tunnel through a conveyer tower located in connection with an outlet end of the shooting tunnel.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
238 words
Automatic cop feeder used in combination with bottomless type cop containers wherein cops are placed in prescribedly defined multiple columns comprising, in combination, an elongated base station whereupon said cop containers are mounted; a conveyor tower through which said cops are transported towards the next operational station one by one and located at one termination of said base station; means for advancing said containers along an upper face of said base station towards said conveyor tower in an intermittent fashion; a guide elongated over a prescribed length along said base station on said upper face so as to temporarily uphold cops in said container when the latter is in engagement therewith; a cop shooting tunnel formed through said base station whose inlet end is open at said upper face of said base station at a location next to a downstream termination of said elongated guide and whose outlet end is open facing said conveyor tower; and a feeler disposed to said cop shooting tunnel which, when the uppermost cop in said cop shooting tunnel falls below the level thereof, senses this lowering and actuates said container advancing means so as to advance said container over a length corresponding to a column width of said cops in said cop container; thereby cops in said container fall into said cop shooting tunnel from column to column and are transported towards said next station through said conveyor tower one by one.
Claim 2
Dependent Claim
238 words
Automatic cop feeder used in combination with bottomless type cop containers wherein cops are placed in prescribedly defined multiple columns comprising, in combination, an elongated base station whereupon said cop containers are mounted; a conveyor tower through which said cops are transported towards the next operational station one by one and located at one termination of said base station; means for advancing said containers along an upper face of said base station towards said conveyor tower in an intermittent fashion; a guide elongated over a prescribed length along said base station on said upper face so as to temporarily uphold cops in said container when the latter is in engagement therewith; a cop shooting tunnel formed through said base station whose inlet end is open at said upper face of said base station at a location next to a downstream termination of said elongated guide and whose outlet end is open facing said conveyor tower; and a feeler disposed to said cop shooting tunnel which, when the uppermost cop in said cop shooting tunnel falls below the level thereof, senses this lowering and actuates said container advancing means so as to advance said container over a length corresponding to a column width of said cops in said cop container; thereby cops in said container fall into said cop shooting tunnel from column to column and are transported towards said next station through said conveyor tower one by one.
Claim 3
Dependent Claim
51 words
Automatic cop feeder as claimed in claim 1, wherein said conveyor tower is internally provided with a circulating endless conveyor, multiple cop pockets formed transversally on said endless conveyor prescribedly spaced from each other along a length of said endless conveyor and a driving source for circulation of said endless conveyor.
Claim 4
Dependent Claim
42 words
Automatic cop feeder as claimed in claim 1, wherein said cop container is provided with multiple internal partitions extending across an advancing direction of said cop container on said base station and cops are placed in columns defined by said internal partitions.
Claim 5
Dependent Claim
76 words
Automatic cop feeder as claimed in claim 3, wherein said container advancing means comprises one or more conveyor belts running along said upper face of said base station, a driving source for causing said running of said one or more conveyor belts and a mechanism connected to said feeler and actuating said driving source only when said feeler senses said lowering of said uppermost cop below said feeler level in said cop shooting tunnel. (FIG. 3)
Claim 6
Dependent Claim
32 words
Automatic cop feeder as claimed in claim 4, wherein a plurality of auxiliary rollers are disposed in combination with said one or more conveyor belts so as to uphold the latter stably.
Claim 7
Dependent Claim
16 words
Automatic cop feeder as claimed in claim 3, wherein said feeler has a mechanical sensing terminal.
Claim 8
Dependent Claim
16 words
Automatic cop feeder as claimed in claim 3, wherein said feeler has a photo-electric seNsing terminal.
Claim 9
Dependent Claim
32 words
Automatic cop feeder as claimed in claim 1, wherein said cop container is provided with vertically fluted side walls, each flute defining a corresponding cop column within said cop column. (FIG. 6)
Claim 10
Dependent Claim
64 words
Automatic cop feeder as claimed in claim 8, wherein said container advancing means comprises an inclined upper face of said base station descending towards said conveyor tower, a stopper mechanism disposed on said upper face in an electrical connection with said feeler so as to stop advancement of said container at prescribed intervals upon intermittent engagement with said fluted side wall of said container.
Claim 11
Dependent Claim
67 words
Automatic cop feeder as claimed in claim 9, wherein said stopper mechanism includes an upright stand fixed on said upper face, a stopper mounted on said upright stand and a solenoid mechanism accompanying said stopper in an electric connection with said feeler so as to cause said stopper to engage with said fluted side wall of said cop contained upon receipt of operational signals from said feeler.
Claim 12
Dependent Claim
15 words
Automatic cop feeder claimed in claim 8, wherein said feeler has a mechanical sensing terminal.
Claim 13
Dependent Claim
15 words
Automatic cop feeder claimed in claim 8, wherein said feeler has a photo-electric sensing terminal.
