Abstract
Abstract A pick-up head for the manipulation of workpieces comprised of tacky material includes a rocker foot capable of four degrees of motion. The pick-up head is mounted on a horizontally movable carriage and includes controllable apparatus for causing the rocker foot to rotate, reciprocate vertically with respect to a table on which the workpieces are positioned and to translate with respect to the remainder of the pick-up head. Horizontal movement of the pick-up head subsequent to establishment of initial contact between the curved rocker foot and a workpiece results in the area of contact between the workpiece and foot increasing and the workpiece may thus be "peeled" from the table or other supporting medium.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
113 words
Apparatus for use in the manipulation of workpieces which are temporarily adhesively bonded to a planar supporting medium comprising: rocker foot means, said rocker foot means having a curved surface adapted to contact a workpiece to be removed from the support medium initially in a narrow linear region; support means for said rocker foot means, said support means permitting translational motion of said rocker foot means with respect to said support means; means for mounting said support means for motion in a plane transverse to the supporting medium; means for reciprocating said support means with respect to said mounting means and the supporting medium; and means for imparting rotation to said support means.
Claim 2
Dependent Claim
113 words
Apparatus for use in the manipulation of workpieces which are temporarily adhesively bonded to a planar supporting medium comprising: rocker foot means, said rocker foot means having a curved surface adapted to contact a workpiece to be removed from the support medium initially in a narrow linear region; support means for said rocker foot means, said support means permitting translational motion of said rocker foot means with respect to said support means; means for mounting said support means for motion in a plane transverse to the supporting medium; means for reciprocating said support means with respect to said mounting means and the supporting medium; and means for imparting rotation to said support means.
Claim 3
Dependent Claim
37 words
The apparatus of claim 1 wherein said rocker foot means comprises: a curved rocker foot; and curved cam track defining members affixed to the side of said rocker foot disposed away from the workpiece contacting surface thereof.
Claim 4
Dependent Claim
44 words
The apparatus of claim 2 wherein said support means comprises: a body; cam means mounted on said body and engaging the cam tracks formed by said rocker foot means cam track defining members; and bearing means for supporting said body from said reciprocating means.
Claim 5
Dependent Claim
65 words
The apparatus of claim 3 wherein said support means further comprises: a motor mounted on said body; a drive chain affixed to the same side of said rocker foot as said cam track defining members; and sprocket means driven by said motor and engaging said chain, energization of said motor imparting translational motion with respect to said support means body to said rocker foot means.
Claim 6
Dependent Claim
38 words
The apparatus of claim 3 wherein said reciprocating means comprises: a fluid operated actuator, said actuator being mounted on said mounting means and having an output piston rod connected to said support means body through said bearing means.
Claim 7
Dependent Claim
38 words
The apparatus of claim 4 wherein said reciprocating means comprises: a fluid operated actuator, said actuator being mounted on said mounting means and having an output piston rod connected to said support means body through said bearing means.
Claim 8
Dependent Claim
59 words
The apparatus of claim 5 wherein said rotation imparting means includes: a foot rotation drive shaft, said drive shaft being coaxial with said actuator piston rod and being directly connected to said rocker foot means body; and motor means for causing rotation of said drive shaft, said motor means being mounted for reciprocation with said rocker foot means body.
Claim 9
Dependent Claim
59 words
The apparatus of claim 6 wherein said rotation imparting means includes: a foot rotation drive shaft, said drive shaft being coaxial with said actuator piston rod and being directly connected to said rocker foot means body; and motor means for causing rotation of said drive shaft, said motor means being mounted for reciprocation with said rocker foot means body.
Claim 10
Dependent Claim
25 words
The apparatus of claim 3 further comprising: clamp means for attaching a releasable sheet of material to the work engaging surface of said rocker foot.
Claim 11
Dependent Claim
25 words
The apparatus of claim 7 further comprising: clamp means for attaching a releasable sheet of material to the work engaging surface of said rocker foot.
Claim 12
Dependent Claim
32 words
The apparatus of claim 10 further comprising: means mounted on said rocker foot means body for providing an indication of said rocker foot reaching a first limit of travel during translational motion.
Claim 13
Dependent Claim
20 words
The apparatus of claim 11 further comprising: means for providing an indication of the rotational position of said rocker foot.
