Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
244 words
A device for transferring annular frustoconical bobbins having a major diameter, a minor diameter and a bore therethrough, from a conveyor belt of a textile machine to pegs of a creel trolley, comprising: (a) a collection station having at least one roller track capable of holding two or more bobbins for laterally guiding the bobbins from the textile machine, wherein said roller track is movable from an inclined position for accepting said bobbins from the conveyor belt to a horizontal position for removal of the bobbins by incline means, and wherein said collection station further comprises confrontation elements movable by activation means for raising each bobbin close to its minor diameter for axially aligning the bobbins; and (b) a portal manipulator unit having a pendant arm, a drive means associated with and driving said pendant arm, and a control unit associated with and controlling said drive means, wherein said pendant arm further comprises a gripper mechanism having a pin for inserting into said bore of at least two of the bobbins on said collection station when said roller track is in its horizontal position and the bobbins are axially aligned by the confrontation elements and positioning said at least two of the bobbins in an axially aligned relationship from said collection station onto the pegs of the creel trolley by means of vertical, horizontal, and rotational translations of said gripper by said drive means associated with said pendant arm controlled by said control unit.
Claim 2
Independent Claim
244 words
A device for transferring annular frustoconical bobbins having a major diameter, a minor diameter and a bore therethrough, from a conveyor belt of a textile machine to pegs of a creel trolley, comprising: (a) a collection station having at least one roller track capable of holding two or more bobbins for laterally guiding the bobbins from the textile machine, wherein said roller track is movable from an inclined position for accepting said bobbins from the conveyor belt to a horizontal position for removal of the bobbins by incline means, and wherein said collection station further comprises confrontation elements movable by activation means for raising each bobbin close to its minor diameter for axially aligning the bobbins; and (b) a portal manipulator unit having a pendant arm, a drive means associated with and driving said pendant arm, and a control unit associated with and controlling said drive means, wherein said pendant arm further comprises a gripper mechanism having a pin for inserting into said bore of at least two of the bobbins on said collection station when said roller track is in its horizontal position and the bobbins are axially aligned by the confrontation elements and positioning said at least two of the bobbins in an axially aligned relationship from said collection station onto the pegs of the creel trolley by means of vertical, horizontal, and rotational translations of said gripper by said drive means associated with said pendant arm controlled by said control unit.
Claim 3
Dependent Claim
48 words
The device of claim 1, wherein said gripper mechanism further comprises an expulsion blade and an expulsion blade actuator for pushing the bobbins from said pin of said gripper mechanism to the peg of the creel trolley, wherein said expulsion blade is driven by said expulsion blade actuator.
Claim 4
Dependent Claim
43 words
The device of claim 2, wherein said control unit of said portal manipulator unit further comprises a data input and a signal output for signalling when the number of bobbins deposited on the creel trolley equals the number entered in said data input.
Claim 5
Dependent Claim
23 words
The device of claim 1, wherein said roller track of said collection station has a substantially V-shaped cross section for cradling the bobbins.
Claim 6
Dependent Claim
43 words
The device of claim 1, wherein said control unit of said portal manipulator unit further comprises a data input and a signal output for signalling when the number of bobbins deposited on the creel trolley equals the number entered in said data input.
Claim 7
Dependent Claim
16 words
The device of claim 5 or 3, wherein said signal output comprises an optical signal output.
Claim 8
Independent Claim
16 words
The device of claims 5 or 3, wherein said signal output comprises an acoustic signal output.
Claim 9
Dependent Claim
60 words
The device of claim 1, wherein the confrontational elements comprise a pair of vertical pins associated with each bobbin on the roller track, said vertical pins each having upper bobbin engagement heads, located on opposite sides of each bobbin whereby said vertical pins are raised and lowered by said activation means to provide horizontal, axial alignment of the bobbin bores.
