SED-120RG-A — Automatic Plastic Tube

Tubes are loaded by hand into side magazines; cam-driven flap units drop them into cup-holder dies on a 38-station 'union' carrier (synchronous-belt loop). The carrier indexes through stations: optional tube cleaning -> color-mark registration (Panasonic photoelectric + servo) -> stainless reciprocating piston-pump filling (valve-body plunger, blow-cut nozzle, 5-220 ml) with bottom-up filling and air-cut to prevent bubbles/dripping -> tail interior heated by Swiss Leister LHS SYSTEM 21L hot-air gun (pinhole head) with external water cooling -> tail sealed and embossed with code -> tail trimmed -> push-out cylinder ejects finished tubes (or onto a conveyor for cartoner linkage). Two independent no-tube/no-filling sensors prevent waste; cam-roller spring action via cylinders ensures constant force.
