Title: Improvements in or relating to Systems for handling articles supported on holders
IPC: B65G47/00
Filed: 1967-10-13
Abstract: 1,188,563. Packaging electronic modules. INTERNATIONAL BUSINESS MACHINES CORP. 13 Oct., 1967 [14 Nov., 1966], No. 46697/67. Heading B8C. [Also in Division F4] Electronic modules (not shown) each comprising a substrate mounted in a metal cap having an upper open end, are contained in the various compartments of trays 12. In operation of a packaging system for the modules, a stack 20 of the module containing trays, is introduced by input conveyer 22 to unstacking station 24, the trays 12 then being passed one at a time under a fluid dispenser 26. This initially dispenses a primer fluid over the substrate in each metal cap, and then dispenses a curable sealing material to seal the joint between the substrate and the cap, to package the module. The trays then pass to a restacking station 28, from where each completed stack is passed by conveyer 30 into a heating enclosure 32 in which the sealing material is cured. The number of trays 12 which form such a completed stack may be varied as desired by means of stack control sensor g, thereby forming a reservoir of trays to compensate for any imbalances occurring during the continuous automatic packaging process. At the stations 24 and 28, the stacks of trays are supported by pivotably mounted rails 36, 66 respectively, engaging the bottom tray of their respective stack, these rails 36, 66 cooperating with vertically movable elevator rods 38, 40 respectively to remove the bottom tray from the stack at station 24, or add a tray to the bottom of the stack at station 28, on actuation of common piston and cylinder drive means 42, 43. Movement of trays 12 between the stations 24, 28 is effected by driven pawls 58 which engage with the bottoms of the trays and are activated by rods 62 and pistons 64. An electronic or pneumatic control for the system (Fig. 5, not shown) is so arranged that the unstacking and stacking drive means 42, 43 operate whenever there are trays to be unstacked at station 24 with no single trays between the stations 24 and 28, or if there is a tray to be restacked at station 28. The drive means for the conveyer 30 operate to load the completed stack of trays at station 28 into the heating enclosure 32, only if such a stack has been completed and there are no trays left to be unstacked by means (not shown) at the exit end of the enclosure. Whenever both the unstacking and stacking drive means 42, 43 and the drive means for the conveyer 30 are not in operation, further control means (not shown) allow the fluid dispenser to operate.
