Abstract
Abstract A device for retrieving a thin slice or wafer of material that has been cut from a billet and for transferring it to a storage receptacle comprises two pivotal members. A first pivotal member retrieves the slice after cutting and moves it along one side of an annular cutting member into a transfer position relative to the inner diameter of the annular member. A second pivotal member takes the slice at the transfer position and moves it axially and then in an arcuate path to a storage receptacle where it is released. The slice of material is retained on the pivotal members by suction. Suitable circuitry controls the application of the suction in proper timed relation to the movement of the pivotal members. A movable support member for the billet is also pivotally mounted so it can move the billet into a position in which it is spaced from the annular member on movement of the latter to its home position, thereby preventing damage to its exposed surface by contact with the annular member. In its home position the billet is moved axially to establish the thickness of the slice to be cut next and then radially relative to the annular member in another cycle of operation to cut the slice. Movement of the support member is also controlled by circuitry interconnected with that for controlling movement of the pivotal members.

213 words
In a device having a flat, rotatable annular member provided with an edge at the inner periphery thereof for cutting a thin slice from an element movable between a first position in which said element is within the inner diameter of said annular member and a second position in which said element is arranged in relation to one surface of said annular member between said inner diameter and the outer periphery of said annular member, the combination comprising: means for supporting said element relative to said annular member comprising a support member pivotally mounted on a movable slide member, said support member being movable between a cutting position and a resetting position; means coupled to said supporting means for moving the latter so said element is moved between said first and second positions; means coupled to said support member for moving the latter and said element between said cutting and resetting positions; and control means responsive to movement of said supporting means into said second position for reversing the direction of movement of said moving means for said support means and for actuating said moving means for said support member whereby said element is moved into and retained in said resetting position for movement thereof between said second position and said first position.
Claim 3
Dependent Claim
116 words
A device in accordance with claim 1 including first means movable relative to the other surface of said annular member and between a retrieval position generally aligned with said second position and a transfer position, said thin slice being retrieved by said first means, when cut and released from said element when the latter is in said second position, for movement to said transfer position which is spaced from said retrieval position; and second means movable between said transfer position and a release position, said second means receiving said thin slice from said first means, when the latter is in said transfer position, for movement to said release position in which said thin slice is discharged.
Claim 4
Dependent Claim
47 words
A device in accordance with claim 2 wherein said control means initiates movement of said first means in timed relAtion to movement of said element into said second position and of said second means in time relation to movement of said first means into said transfer position.
Claim 5
Dependent Claim
79 words
A device in accordance with claim 1 including means actuated by said control means for indexing said element, upon movement of said supporting means from said second position to said first position and of said element from said resetting position into said cutting position, to establish the relation of said element to said annular member, thereby determining the thickness of that slice to be cut when said element is next moved from said first position to said second position.
Claim 6
Dependent Claim
53 words
A device in accordance with claim 4 including means responsive to said supporting means, upon movement of said elements into said first position, for moving said support member into said cutting position, whereby said element is positioned relative to said annular member for establishing the thickness of the slice next to be cut.
Claim 7
Dependent Claim
35 words
A device in accordance with claim 2 wherein said control means initiates movement of said supporting means from said second position to said first position upon movement of said second means into said release position.
Claim 8
Dependent Claim
68 words
A device in accordance with claim 2 wherein said control means initiates movement of said first means and said second means, said first means moving from said retrieval position to said transfer position and said second means moving from said release position to said transfer position, and means for effecting transfer of said thin slice from said first means to said second means when in said transfer position.
