Material handling device

Claim 2

Claim 5

A pneumatic handling device comprising frame means, pneumatic means for picking up a relatively thin flat-sided member, such as punch cards, means mounted on the frame means for moving the pick-up means between a first position to pick up such a member and a second position to deliver the member with a pause at each position, and means to remove the member from the pick-up means when the pick-up means is in said second position, said member removal means including first and second rollers, means mounting the rollers on the frame means for rotation around their longitudinal axes, means for rotating the rollers in opposite directions around their respective longitudinal axes, said mounting means including means mounting at least one of the rollers for pivotal movement of its longitudinal axis around the longitudinal axis of the other roller, means for moving the pivotally mounted roller between a first roller position where the rollers are positioned to receive between the two rollers a member from the pick-up means when the pick-up means is in its second position and a second roller position to discharge the member from between the rollers in a direction at an angle to the direction of travel of the member when it was first engaged by the rollers.

Claim 6

The device of claim 3 in which said roller moving means includes a second cam, means mounting the second cam for rotation, a follower member operatively engaged with the movable roller and the second cam for causing the roller to move between its first and second positions as the cam is rotated, and means for rotating the second cam to so move the movable roller.

Claim 7

A card handling device for moving cards, such as data processing cards, one at a time from a stack of such cards, comprising two frame sides, a cam shaft mounted on said frame sides for rotation relative thereto around its longitudinal axis, a cam mounted on and rotating with said cam shaft, said cam having a peripheral surface with an arcuate portion having a relatively long radius of curvature with respect to the longitudinal axis of the shaft, an arcuate portion having a relatively short radius of curvature with respect to the longitudinal axis of the shaft, and generally straight portions connecting said two arcuate portions, an L-shaped arm positioned between the frame sides with one end mounted to pivot around an axis generally parallel to the longitudinal axis of said cam shaft, said arm having an opening in which said cam is positioned for its peripheral surface to engage the sides of the opening, a suction bar attached to said L-shaped arm at a location spaced from its pivotal axis to pick up one card from the top of the stack of such cards, meanS for rotating the shaft in order to rotate said cam and oscillate the arm around its pivotal axis to move the suction bar between a first position in engagement with a stack of such cards with a pause in the movement of such arm when in such position that is sufficient to allow the top card to become attached to the suction bar and a second position where the card is removed from the suction bar with a pause in the movement of the bar at said second position, and means for so removing the card, said means comprising a first roller shaft mounted on said frame sides for rotation about its longitudinal axis, said first roller mounted on said first roller shaft for rotation about the longitudinal axis of said first roller shaft, a pivotal link mounted on said first roller shaft in such a manner that said link is pivotal about said first roller shaft longitudinal axis, said frame sides having arcuate slots, a second roller shaft extending through said arcuate slots and through said pivotal link in such a manner that said second roller is pivotal through said arcuate slots about the longitudinal axis of said first roller shaft, a gear mounted on each of said first and second roller shafts in such a manner that rotation of said one of said gears causes the other of said gears to rotate and thereby causes said rollers to rotate, means moving said pivotally mounted second roller between a first roller position where said rollers are positioned to receive between the rollers a card when said suction bar is in its second position, comprising an eccentric mounted for rotation on said cam shaft, a follower arm connected on one end to said pivotal link and on the other end having a circular opening therein fitting over said eccentric such that rotation of said eccentric causes oscillation of said second roller between a first roller position where said rotating rollers remove said card from said suction bar in said second suction bar position and a second roller position where the card is released at an angle with respect to the position of the cards in said stack.

Claim 8

A card handling device for moving cards, such as data processing cards, one at a time from a stack of such cards, comprising two frame sides, a cam shaft mounted on said frame sides for rotation relative thereto around its longitudinal axis, a cam mounted on and rotating with said cam shaft, said cam having a peripheral surface with an arcuate portion having a relatively long radius of curvature with respect to the longitudinal axis of the shaft, an arcuate portion having a relatively short radius of curvature with respect to the longitudinal axis of the shaft, and generally straight portions connecting said two arcuate portions, an L-shaped arm positioned between the frame sides with one end mounted to pivot around an axis generally parallel to the longitudinal axis of said cam shaft, said arm having an opening in which said cam is positioned for its peripheral surface to engage the sides of the opening, a suction bar attached to said L-shaped arm at a location spaced from its pivotal axis to pick up one card from the top of the stack of such cards, meanS for rotating the shaft in order to rotate said cam and oscillate the arm around its pivotal axis to move the suction bar between a first position in engagement with a stack of such cards with a pause in the movement of such arm when in such position that is sufficient to allow the top card to become attached to the suction bar and a second position where the card is removed from the suction bar with a pause in the movement of the bar at said second position, and means for so removing the card, said means comprising a first roller shaft mounted on said frame sides for rotation about its longitudinal axis, said first roller mounted on said first roller shaft for rotation about the longitudinal axis of said first roller shaft, a pivotal link mounted on said first roller shaft in such a manner that said link is pivotal about said first roller shaft longitudinal axis, said frame sides having arcuate slots, a second roller shaft extending through said arcuate slots and through said pivotal link in such a manner that said second roller is pivotal through said arcuate slots about the longitudinal axis of said first roller shaft, a gear mounted on each of said first and second roller shafts in such a manner that rotation of said one of said gears causes the other of said gears to rotate and thereby causes said rollers to rotate, means moving said pivotally mounted second roller between a first roller position where said rollers are positioned to receive between the rollers a card when said suction bar is in its second position, comprising an eccentric mounted for rotation on said cam shaft, a follower arm connected on one end to said pivotal link and on the other end having a circular opening therein fitting over said eccentric such that rotation of said eccentric causes oscillation of said second roller between a first roller position where said rotating rollers remove said card from said suction bar in said second suction bar position and a second roller position where the card is released at an angle with respect to the position of the cards in said stack.
