Abstract

Heads A and B (Fig. 1) and the side rails C and D (Fig. 5) on each are cleaned by means of arm 7 and particularly by means of cloth 10 wrapping the thin forepart 7a of arm 7 to which FREON* TF is supplied as a cleaning agent. Bottle 1 holds FREON TF and is mounted on standard 12. Bottle 1 contains an exhaust manifold 2, a level switch 3, which indicates when the fluid FREON is low, and fittings for tubing 4. Tubing 4 is routed to a normally closed valve 5 which is connected to arm 7. Arm 7 is mounted on a pneumatic thruster 14 which provides the scrubbing action when heads A and B and rails C and D are contacted by cloth 10 supported by arm portion 7a. The fluid FREON flows through valve 5 and thence through tubing 6 (Fig. 3) which is of such a small internal diameter, such as 0.

Gravity-Feed Head Cleaner

Heads A and B (Fig. 1) and the side rails C and D (Fig. 5) on each are cleaned by means of arm 7 and particularly by means of cloth 10 wrapping the thin forepart 7a of arm 7 to which FREON* TF is supplied as a cleaning agent. Bottle 1 holds FREON TF and is mounted on standard 12. Bottle 1 contains an exhaust manifold 2, a level switch 3, which indicates when the fluid FREON is low, and fittings for tubing 4. Tubing 4 is routed to a normally closed valve 5 which is connected to arm 7. Arm 7 is mounted on a pneumatic thruster 14 which provides the scrubbing action when heads A and B and rails C and D are contacted by cloth 10 supported by arm portion 7a. The fluid FREON flows through valve 5 and thence through tubing 6 (Fig. 3) which is of such a small internal diameter, such as 0.5 mm, to provide a restriction to the flow of the FREON (under gravity flow) to provide a constant amount of FREON regardless of how full or empty bottle 1 is. Valve 5 is electronically

opened for a predetermined time, such as from 40 to 600 milliseconds, which also helps to determine the amount of FREON dispensed. From tubing 6, the fluid flows through four small (such as 0.008" diameter) holes 16 provided in arm portion 7a and is then distributed to cloth 10, which may be polyester. Cloth 10 is clamped on arm portion 7a by means of spring clamps 18 and 20 (Fig.4). Thruster 14 is moved forwardly in direction F by means of air cylinder 22, and arm...
