Abstract

In labelling machines employing a liquid ink to develop the address image on a photoreceptor, the ink may spill if the machine is jarred or tipped. To reduce this possibility, a semi-closed ink system is described.

In labelling machines employing a liquid ink to develop the address image on a photoreceptor, the ink may spill if the machine is jarred or tipped. To reduce this possibility, a semi-closed ink system is described.

Referring to the drawing, ink reservoir 5 is sealed and leak proof with all tubing inlets and outlets sealed except for vent tube 6. A screw type cap 7 is provided for filling the reservoir with fresh ink. The gear type ink supply pump 8 can be driven with a small motor 4 (or from the machine drive system). The developer housing 9 is made from plastic with a drain I0 on the bottom. A developer distributing manifold 11 has 14-18 small holes or orifices ,I2 positioned to squirt ink at the applicator roll 14, the latter serving to apply the developer ink to the image on the surface of photoreceptor drum 15. No heater, ink roll, or float assembly are required. A small self priming pump 16 which can be driven with a motor or from the machine drive system is provided for returning unused developer ink to the ink reservoir 5.

SPILLPROOF INK SUPPLY (Cont'd)

In operation, with the machine turned on, the ink supply gear pump 8 starts pumping ink to the manifold 11 in the developer housing 9. When the ink head pressure builds up in the manifold 11, th...
