Abstract
Abstract Bobbin handling apparatus in which bobbins are stored in random orientation in a hopper and are delivered by the apparatus in an oriented manner. The bobbins in the hopper are agitated by a member movable vertically through the hopper. This member has an upwardly open mouth and upon upward movement of the member the mouth receives small ends of a portion of the bobbins in the hopper with large ends of the bobbins resting on the member adjacent the mouth. A pusher is provided for moving the bobbins to one end of the mouth from which they are received between a pair of downwardly inclined rods rotated in opposite directions so as to lift the bobbins and permit them to move down the rods to an escapement. When a bobbin is required, the escapement opens to permit a bobbin to be discharged through a chute to a conveyor belt with the bobbins oriented on the belt with smaller ends leading.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
144 words
Bobbin handling mechanism comprising a hopper for holding bobbins in random orientation, bobbin orienting means mounted for movement within said hopper for gathering bobbins from said hopper and orienting said gathered bobbins, means for discharging said bobbins from said orienting means, means for receiving the bobbins so discharged from the orienting means and operable for releasing the oriented bobbins, said bobbin orienting means including a slidable member, means mounting said slidable member for movement within said hopper between upper and lower positions, means operable for moving said member between said positions, the slidable member having opposite ends, the mounting means including guide means on the hopper for receiving the respective ends of the slidable member, the moving means including an actuator movable in a generally parallel direction with respect to said guides, and means connecting said actuator with said actuator with said slidable member.
Claim 2
Dependent Claim
144 words
Bobbin handling mechanism comprising a hopper for holding bobbins in random orientation, bobbin orienting means mounted for movement within said hopper for gathering bobbins from said hopper and orienting said gathered bobbins, means for discharging said bobbins from said orienting means, means for receiving the bobbins so discharged from the orienting means and operable for releasing the oriented bobbins, said bobbin orienting means including a slidable member, means mounting said slidable member for movement within said hopper between upper and lower positions, means operable for moving said member between said positions, the slidable member having opposite ends, the mounting means including guide means on the hopper for receiving the respective ends of the slidable member, the moving means including an actuator movable in a generally parallel direction with respect to said guides, and means connecting said actuator with said actuator with said slidable member.
Claim 3
Dependent Claim
42 words
Mechanism as set forth in claim 1, in which said moving means is a cylinder, said actuator is the piston rod of said cylinder, and the connecting means is a ball and socket connection between the piston rod and the slidable member.
Claim 4
Dependent Claim
82 words
Mechanism as set forth in claim 2, in which the discharging means is operable for moving the bobbins in an upwardly opening mouth provided in the slidable member, said mouth being provided to receive the bobbins from said hopper, the discharging means being operable to receive the bobbins in said mouth only when said slidable member is generally in its upper position, and said discharging means comprising pusher means mounted for movement through said mouth to engage and move the bobbins therefrom.
Claim 5
Dependent Claim
96 words
Mechanism as set forth in claim 3, in which the pusher means comprises a double-acting cylinder fixedly mounted above said mouth, said cylinder having a piston, a pusher assembly including a carrier and a pusher mounted on said carrier and extending into said mouth when said slidable member is in its upper position, a track mounting said carrier for movement to and fro along said mouth, cable means having opposite ends connected to said piston and connected with said carrier for moving the carrier to and fro along said mouth responsive to actuation of said cylinder.
Claim 6
Dependent Claim
39 words
Mechanism as set forth in claim 4, in which said discharging means comprises means for returning said pusher means to a waiting position after movement of the pusher through said mouth to move the bobbins toward said receiving means.
Claim 7
Dependent Claim
37 words
Mechanism as set forth in claim 5, in which the return means is operable for returning said pusher means to said waiting position is responsive to bobbins in excess of a predetermined member to said receiving means.
Claim 8
Dependent Claim
25 words
Mechanism as set forth in claim 6, in which said return means comprises an actuator pivoted to said hopper and engageable by said pusher means.
Claim 9
Dependent Claim
143 words
Mechanism as set forth in claim 1, in which the bobbins each have larger and smaller ends, the receiving means including a pair of spaced apart generally parallel supports for receiving the oriented bobbins from said slidable member with their smaller ends in the space between said supports and tHeir larger ends resting on said supports, said supports being inclined downwardly from a receiving end adjacent said hopper to a releasing end and spaced from said hopper, means including rod means mounting said supports for rotation in opposite directions to thereby urge said bobbins downwardly along said supports, in which the releasing ends of said rods are formed with an opening for the passage of the larger end of a bobbin therethrough, and in which said receiving means includes escapement means for releasing the bobbins to pass through the opening in said rods.
Claim 10
Dependent Claim
84 words
Mechanism as set forth in claim 8, in which said escapement means comprises a pair of abutments, one normally in position to engage the lowermost bobbin on said rods and the other normally positioned spaced from said bobbins for movement into a bobbin holding position between the two lowermost bobbins on said rods, and means for moving said other rod into said holding position and said one rod away from said lowermost bobbin to permit the last said bobbin to pass through said opening.
Claim 11
Dependent Claim
111 words
Mechanism as set forth in claim 8, in which said hopper has opposed sides converging downwardly for movement of the randomly oriented bobbins therein toward a lower portion of the hopper, and said bobbin orienting means includes a slidable member, said slidable member having an upwardly opening mouth for receiving the bobbins from said hopper with their smaller ends within the mouth and their larger ends resting on the member along said mouth, means mounting said slidable member for movement within said hopper between upper and lower positions with said slidable member extending between said sides generally along said lower portion, and means operable for moving said member between said positions.
Claim 12
Dependent Claim
44 words
Mechanism as set forth in claim 10, in which the discharging means includes an abutment movable through said mouth when said member is generally in its upper position means mounting said abutment for movement along said mouth, and means operable for moving said abutment.
