Abstract
Abstract A device for handling thin, waferlike elements and by which such elements can be transferred discretely from a supply stack to a rotatable carrier and from said carrier to a receiving stack. The transfer is accomplished by a mechanism that is operated in timed relation to the rotation of the carrier and by means of a vacuum that is applied for a period of time sufficient to effect the transfer. The mechanism includes an arrangement of members whereby one of the members is maintained in a path of movement that is the same as that of said element when on said carrier. During such maintenance period, the element is deposited on the carrier or removed therefrom.

Claim 1
Independent Claim
346 words
A device for positioning each successive element presented by a stack of said elements on a respective one of each of a plurality of supporting members arranged on a movable carrier, said stack of elements being arranged adjacent said carrier, the combination comprising: a first support member; a second support member pivotally mounted on said first support member; reversible drive means arranged on said second support member; a vacuum source; first means pivotally and slidably mounted on said second support member and coupled to said drive means for cyclic movement between a first position in which it is disengaged from one of said supporting members, a second position in which it engages and is held in engagement with one of said supporting members, and a third position into which it is moved with said second support member by said carrier; second means connectable to said vacuum source and pivotally mounted on said first means and movable therewith and relative thereto between a first position relative to said stack for picking up one of said elements and a second position relative to one of said supporting members for positioning said one element on said supporting member; means interconnecting said first and second means and said second support means so that movement of said drive means in one direction moves said first and second means from said first portions to said second positions and maintains said first and second means in said second positions relative to said one supporting member during a predetermined movement of said carrier and in the other direction returns said first and second means to said first position; and means responsive to movement of each successive supporting member into a predetermined position relative to said stack for connecting said vacuum source to said second means and for initiating movement of said drive means in said one direction, and to movement of said second support member into said third position for disconnecting said vacuum source from said second means to release said one element and for reversing the direction of movement of said drive means.
Claim 2
Independent Claim
346 words
A device for positioning each successive element presented by a stack of said elements on a respective one of each of a plurality of supporting members arranged on a movable carrier, said stack of elements being arranged adjacent said carrier, the combination comprising: a first support member; a second support member pivotally mounted on said first support member; reversible drive means arranged on said second support member; a vacuum source; first means pivotally and slidably mounted on said second support member and coupled to said drive means for cyclic movement between a first position in which it is disengaged from one of said supporting members, a second position in which it engages and is held in engagement with one of said supporting members, and a third position into which it is moved with said second support member by said carrier; second means connectable to said vacuum source and pivotally mounted on said first means and movable therewith and relative thereto between a first position relative to said stack for picking up one of said elements and a second position relative to one of said supporting members for positioning said one element on said supporting member; means interconnecting said first and second means and said second support means so that movement of said drive means in one direction moves said first and second means from said first portions to said second positions and maintains said first and second means in said second positions relative to said one supporting member during a predetermined movement of said carrier and in the other direction returns said first and second means to said first position; and means responsive to movement of each successive supporting member into a predetermined position relative to said stack for connecting said vacuum source to said second means and for initiating movement of said drive means in said one direction, and to movement of said second support member into said third position for disconnecting said vacuum source from said second means to release said one element and for reversing the direction of movement of said drive means.
Claim 3
Dependent Claim
83 words
A device in accordance with claim 1 wherein said interconnecting means comprises a pair of spaced pins fixed to said secured support member, one of said pins engaging a longitudinal slot in said first means and the other pins extending through said slot and engaging a cam slot in said second means, said pins and slots being arranged between the pivotal axes for said second support member, first means and second means, on the one hand, and said carrier, on the other hand.
Claim 4
Dependent Claim
51 words
A device in accordance with claim 1 wherein said second means comprises a plate pivotally mounted on said first means and movable therewith and relative thereto, a third support member fixed to said plate, and an element engaging means secured to said third support member and connectable to said vacuum source.
Claim 5
Dependent Claim
17 words
A device in accordance with claim 1 wherein said reversible drive means comprises a fluid operated member.
Claim 6
Dependent Claim
17 words
A device in accordance with claim 1 wherein said reversible drive means comprises a pneumatically operated member.
Claim 7
Dependent Claim
71 words
A device in accordance with claim 1 wherein said first means comprises a pivotally mounted plate having a pair of spaced and freely rotatable rollers mounted on one end thereof for engaging each of said supporting members when said plate is in said second position and being held in such engaging relationship for maintaining said second means in said second position until said one element is positioned on said supporting means.
