Abstract
Abstract An apparatus for automatically inserting and retrieving cathode ray tube face panels from a panel processor which includes a programmer and an endless conveyor that carries a plurality of panel supporting carts. A prime mover controlled by the programmer steps the carts through a series of work stations, including an index station, disposed along a closed path. The apparatus comprises a platen having a pair of panel holders successively displaceable between the index station and a loading station. Means are provided for effecting a first reciprocation of the panel holder at the index station into engagement with an indexed cart to insert an unprocessed panel therein and thereafter, upon a second reciprocation to retrieve a processed panel from a subsequently indexed cart. Finally, platen driving means are provided for displacing the panel holder with the retrieved panel to the loading station while simultaneously displacing the other panel holder to the index station to insert an unprocessed panel into the subsequently indexed cart.

Claim 1
Independent Claim
198 words
Apparatus for automatically inserting and retrieving cathode ray tube face panels from a panel processor, said processor including a programmer, an endless conveyor carrying a plurality of panel supporting carts and a prime mover, controlled by said programmer for stepping said carts through a series of work stations, including an index station, disposed along a closed path, said apparatus comprising: a platen having a plurality of panel holders successively displaceable between said index station and a loading station; means for effecting a first reciprocation of at least that one of said panel holders instantaneously located at said index station into cooperative engagement with a first indexed one of said carts for inserting an unprocessed panel in said first cart and for thereafter effecting at said second station a second reciprocation of said one panel holder into cooperative engagement with a subsequently indexed cart for retrieving a processed panel from said subsequent cart; and platen driving means for displacing said one panel holder and said retrieved processed panel to said loading station while simultaneously displacing another of said panel holders carrying an unprocessed panel to said index station for insertion into said subsequently indexed cart by said reciprocation means.
Claim 2
Dependent Claim
198 words
Apparatus for automatically inserting and retrieving cathode ray tube face panels from a panel processor, said processor including a programmer, an endless conveyor carrying a plurality of panel supporting carts and a prime mover, controlled by said programmer for stepping said carts through a series of work stations, including an index station, disposed along a closed path, said apparatus comprising: a platen having a plurality of panel holders successively displaceable between said index station and a loading station; means for effecting a first reciprocation of at least that one of said panel holders instantaneously located at said index station into cooperative engagement with a first indexed one of said carts for inserting an unprocessed panel in said first cart and for thereafter effecting at said second station a second reciprocation of said one panel holder into cooperative engagement with a subsequently indexed cart for retrieving a processed panel from said subsequent cart; and platen driving means for displacing said one panel holder and said retrieved processed panel to said loading station while simultaneously displacing another of said panel holders carrying an unprocessed panel to said index station for insertion into said subsequently indexed cart by said reciprocation means.
Claim 3
Dependent Claim
19 words
Apparatus as set forth in claim 1 in which said platen comprises a pair of oppositely disposed panel holders.
Claim 4
Dependent Claim
31 words
Apparatus as set forth in claim 1 which further includes a rotatably supported post coupled to said platen for displacing said panel holders between said index station and said loading station.
Claim 5
Dependent Claim
42 words
Apparatus as set forth in claim 1 in which said means for effecting reciprocation of said panel holder comprises a rotatably mounted reversible cam displaceable through an arcuate distance of 540* in effecting said first and second reciprocations of said panel holders.
Claim 6
Dependent Claim
32 words
Apparatus as set forth in claim 3 which further includes a multi-arm hanger supporting a like plurality of aperture masks and mounted upon said post for conjoint rotation with said panel holders.
Claim 7
Dependent Claim
41 words
Apparatus as set forth in claim 5 which further includes a control shaft disposed within said post for actuating said hanger to deposit that one of said aperture masks instantaneously located at said index station upon a cart borne mask holder.
Claim 8
Dependent Claim
48 words
Apparatus as set forth in claim 6 which additionally includes a reversible rotatably mounted cam displaceable through an arcuate travel of 270* for depositing a mask upon said first cart during said first reciprocation and for removing a mask from said subsequently indexed cart during said second reciprocation.
Claim 9
Dependent Claim
28 words
Apparatus as set forth in claim 1 which further includes means for automatically elevating that one of said panel holders entering said loading station to a predetermined elevation.
Claim 10
Dependent Claim
50 words
Apparatus as set forth in claim 8 in which said elevating means comprises a circular track undulating from a reference elevation at said index station to said predetermined elevation at said loading station and a cam follower depending from each of said panel holders in continuous engagement with said track.
