Drip Chamber Assembly Machine

MACHINE NO. 2369
Welds four (4) drip chambers per cycle. Because of their inconsistent shape, the tubes are manually loaded into the nest and tested for presence. The machine stops if any are missing. Four (4) bottom caps are loaded from two feeder bowls, tested for presence, RF welded to the tubes then spikes are assembled on top of the tubes. Tested for presence and RF welded. The assembly is pressurized to 10 psi and tested for pressure drop, after which the breather cap is loaded on to the tubes. The assembly is finally tested for the presence of all pens and either ejected in the good bin or rejected. Three consecutive rejects at any station will stop the machine and an indicator light pinpoints the problem area.

The equipment is Solid State controlled and designed for operators capability to physically overlook all stations during operation of the machine and ease of service.

CONSTRUCTION -The machine has a heavy-duty welded and stress released steel base with integral channels for operating air, exhausts and wiring. All stations are mounted against standard mounting plates with common dowel pin patterns and are interchangeable with plug-in control lines. All wiring and electronic controls are shielded against RF interference.

The large dial plate is a sandwich construction and hollow to reduce mass, with a nylon rim for RF tooling insulation.

CYCLE RATE – Machine is programmed to 720 cycles per hour x 4 up equals, 2880 assemblies per hour. Speed related to RF welding time required.

SEQUENCER – The machine sequence is controlled by a Texas Instrument programmable controller.

MACHINE CONTROL – All controls are within reach of the operator on one panel. Controls include individual bowl and linear feeders, speed controls, on/off power switch, emergency switch, indexer and sequencer control, automatic single jog cycle, individual station control for set-up, II. timer for RF welder, welder on/oft, table index safety switch, sensors indicator lights and reset button.
