Abstract
Abstract Automatic cop feeder for feeding cops mounted in a container one by one in succession through a delivery path formed in the container to the next operational station while breaking possible cop bridges near inlet of the delivery path by giving shaking effect to cops in the container through alternate forward and return i.e. to and fro movements of an endless belt mounted at the bottom of the container.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
151 words
Automatic cop feeder comprising, in combination, a substantially upright cop container having at the bottom thereof a cop delivery path along which cops are to be delivered to an outlet terminals, an endless belt disposed at the bottom of said container and having a horizontal upper run extending into the interior of said cop container from the bottom for transporting cops lying thereon towards said outlet terminal in response to forward movement of said upper run in a direction towards said outlet terminal, means for imparting alternate forward and return movements to said endless belt, transporting means for transporting cops delivered one by one from said outlet terminal of said cop delivery path towards the next operational terminal, and means for actuating said imparting means at prescribed intervals for said foward and return movements of said endless belt to prevent the cops from forming a blockage along said cop delivery path.
Claim 2
Dependent Claim
151 words
Automatic cop feeder comprising, in combination, a substantially upright cop container having at the bottom thereof a cop delivery path along which cops are to be delivered to an outlet terminals, an endless belt disposed at the bottom of said container and having a horizontal upper run extending into the interior of said cop container from the bottom for transporting cops lying thereon towards said outlet terminal in response to forward movement of said upper run in a direction towards said outlet terminal, means for imparting alternate forward and return movements to said endless belt, transporting means for transporting cops delivered one by one from said outlet terminal of said cop delivery path towards the next operational terminal, and means for actuating said imparting means at prescribed intervals for said foward and return movements of said endless belt to prevent the cops from forming a blockage along said cop delivery path.
Claim 3
Dependent Claim
36 words
Automatic cop feeder as claimed in claim 1, wherein said last-mentioned means includes means for making the stroke and speed of said forward movement of said endless belt equal to those of said return movement thereof.
Claim 4
Dependent Claim
37 words
Automatic cop feeder ac claimed in claim 1, wherein said last-mentioned means includes means for making the stroke and speed of said forward movement of said endless belt are larger than those of said return movement thereof.
Claim 5
Dependent Claim
45 words
Automatic cop feeder as claimed in claim 1, further comprising a rotatable bridge breaker roller disposed facing an inlet terminal of said cop delivery path and mechanically connected to said imparting means for rotation thereof in synchronism with said forward movement of said endless belt.
Claim 6
Dependent Claim
18 words
Automatic cop feeder as claimed in claim 4, including means mounting said bridge breaker roller for eccentric rotation.
Claim 7
Dependent Claim
97 words
Automatic cop feeder as claimed in claim 1, wherein said imparting means includes a pair of spatially arranged driver rollers over which said endless belt runs, a driving source connected to oNe of said driver roller, an electromagnetic clutch disposed between said driving source and said one driver roller for clutching same together to effect forward movement of said endless belt, another driving source connected to the other one of said driver rollers for effecting return movement of said endless belt, and a ratchet wheel mechanism disposed between said another driving source and said other driver roller.
Claim 8
Dependent Claim
24 words
Automatic cop feeder as claimed in claim 6, further comprising a variable speed controller inserted between said electromagnetic clutch and said one driver roller.
Claim 9
Dependent Claim
42 words
Automatic cop feeder as claimed in claim 1, wherein said cop container is provided inside with an inward extension disposed on a cop discharge side wall of said cop container and whose bottom wall defines a ceiling of said cop delivery path.
Claim 10
Dependent Claim
43 words
Automatic cop feeder as claimed in claim 8, wherein said inward extension comprises a swing plate pivoted at said cop discharge side wall of said cop container, and resilient means for resiliently urging said swing plate toward the interior of said cop container.
Claim 11
Dependent Claim
46 words
Automatic cop feeder as claimed in claim 8, wherein said inward extension comprises a swing plate pivoted at said cop discharge side wall of said cop container, and means including a crank mechanism for periodically swinging said swing plate towards the interior of said cop container.
Claim 12
Dependent Claim
99 words
Automatic cop feeder as claimed in claim 1, wherein said transporting means includes an endless belt conveyer having transversely extending cop pockets which are located at selected interval along the length of said belt conveyer and running partly facing said outlet terminal of said cop delivery path for one by one receipt of said cops into said cop pockets, and a pair of driver skeletons spaced from each other and over which said belt conveyer runs and one of which is connected to said imparting means for circulation in synchronism with said return movement of said bottom endless belt.
Claim 13
Dependent Claim
81 words
Automatic cop feeder as claimed in claim 11, wherein said driver skeleton comprises a plurality of polygonal discs spacially aligned on a rotational shaft, and wherein said belt conveyer comprises multiple caterpillar segments connected in succession by pin joints and each having a length corresponding to one side length of each polygonal disc and said cop pocket is provided with slits for allowing insertion therein of said polygonal discs when its associated caterpiller segment comes in contact with said driver skeleton.
Claim 14
Dependent Claim
60 words
Automatic cop feeder as claimed in claim 11, further comprising a pair of guide rails disposed near an upper termination of said endless conveyer and each having its upper end curved towards said next operational station in such an arrangement that both cop ends contact said guide rails when said cop held in said cop pocket approches said upper termination.
