Claim 1
Independent Claim
405 words
Apparatus for segregating wafer-like objects into groups each containing a preselected number of said objects, and for dispensing said groups of objects separately onto predetermined different receiving surface regions, comprising: a storage chamber for receiving and temporarily storing said groups of objects; controllably actuatable dispensing means for dispensing said groups of objects from said chamber; object-receiving means having a plurality of receiving surface regions upon each of which a different one of said groups is to be dispensed; means for successively moving said receiving surface regions adjacent said dispensing means to receive said groups of objects on said receiving surface regions, upon sequential appropriately-timed actuations of said dispensing means; delivery-line means for receiving a generally horizontal edge-supported face-abutting array of said wafer-like objects and for delivering said objects sequentially into said chamber to form said groups of objects; and control means for controlling said dispensing means to effect said dispensing of said groups of objects from said chamber onto said surface regions; said controllably actuatable dispensing means comprising a rotatable gate forming the bottom of said storage chamber, and gate actuating means for rotating said gate upon signal from said control means to temporarily open the bottom of said storage chamber to permit discharge of said groups of objects; said gate actuating means comprising a continuously rotating shaft, and clutch means connected with said shaft and said gate for rotating said gate through a predetermined arcuate path upon receipt of a signal from said control means; said control means comprising means for sensing times at which each of said groups of objects is in said chamber and when one of said receiving surface regions is in position to receive each said group of objects, and for actuating said dispensing means only at such times; means for sensing times at which an additional object is about to be delivered to said storage chamber while said chamber contains a group of said selected number of said objects, and means for delaying the delivery of said additional object so that it is not delivered to said chamber until after the group of objects in said chamber has been dispensed; wherein said means for delaying operation of said delivery-line means comprises means for stopping said delivery-line means when said additional object is about to be delivered to said chamber, thereby to prevent said delivery of said additional object until after said predetermined number of said objects have been dispensed.

Apparatus for segregating wafer-like objects into groups each containing a preselected number of said objects, and for dispensing said groups of objects separately onto predetermined different receiving surface regions, comprising: a storage chamber for receiving and temporarily storing said groups of objects; controllably actuatable dispensing means for dispensing said groups of objects from said chamber; object-receiving means having a plurality of receiving surface regions upon each of which a different one of said groups is to be dispensed; means for successively moving said receiving surface regions adjacent said dispensing means to receive said groups of objects on said receiving surface regions, upon sequential appropriately-timed actuations of said dispensing means; delivery-line means for receiving a generally horizontal edge-supported face-abutting array of said wafer-like objects and for delivering said objects sequentially into said chamber to form said groups of objects; and control means for controlling said dispensing means to effect said dispensing of said groups of objects from said chamber onto said surface regions; said controllably actuatable dispensing means comprising a rotatable gate forming the bottom of said storage chamber, and gate actuating means for rotating said gate upon signal from said control means to temporarily open the bottom of said storage chamber to permit discharge of said groups of objects; said gate actuating means comprising a continuously rotating shaft, and clutch means connected with said shaft and said gate for rotating said gate through a predetermined arcuate path upon receipt of a signal from said control means; said control means comprising means for sensing times at which each of said groups of objects is in said chamber and when one of said receiving surface regions is in position to receive each said group of objects, and for actuating said dispensing means only at such times; means for sensing times at which an additional object is about to be delivered to said storage chamber while said chamber contains a group of said selected number of said objects, and means for delaying the delivery of said additional object so that it is not delivered to said chamber until after the group of objects in said chamber has been dispensed; wherein said means for delaying operation of said delivery-line means comprises means for stopping said delivery-line means when said additional object is about to be delivered to said chamber, thereby to prevent said delivery of said additional object until after said predetermined number of said objects have been dispensed.
Claim 3
Dependent Claim
19 words
The apparatus of claim 1 wherein said gate comprises a substantially horizontal blade-like member rotatable about a vertical axis.
Claim 4
Dependent Claim
63 words
The apparatus of claim 1 wherein said control means comprises an electronic control system, responsive to first signals indicative of the time of arrest of each of said object receiving means in loading position, and to second signals indicative of the delivery of a predetermined number of said objects into said chamber, for operating said dispensing means to dispense said groups of objects.
Claim 5
Dependent Claim
60 words
The apparatus of claim 1 comprising means for delaying operation of said delivery-line means in the event one of said objects in addition to said predetermined number thereof is about to be delivered to said chamber, for a time sufficient for completion of the dispensing of the preceding predetermined number of said objects before said one object reaches said chamber.
