Abstract
A highly-viscous-fluid applying apparatus including a fluid supply device operable to supply a highly viscous fluid, a delivery nozzle from which the highly viscous fluid is delivered, a pump disposed between the fluid supply device and the delivery nozzle and operable to feed the highly viscous fluid received from the fluid supply device, to the delivery nozzle, and a pump control device operable to control the pump, for controlling an amount of delivery of the highly viscous fluid to be delivered from the delivery nozzle.
Claims23
A highly-viscous-fluid applying apparatus comprising:
- a fluid supply device operable to supply a highly viscous fluid;
- a delivery nozzle from which the highly viscous fluid is delivered;
- a screw pump disposed between said fluid supply device and said delivery nozzle, and including a stationary screw that is non-rotatable, and a rotatable pump housing having a screw chamber of a circular shape in transverse cross section, said rotatable rump housing accommodating said stationary screw substantially fluid-tightly and being rotatable about an axis of said stationary screw, said screw being operable to deliver the highly viscous fluid received from said fluid supply device, from said delivery nozzle, by rotation of said rotatable pump housing about the axis of said stationary screw;
- and
- a pump control device including a pump drive device operable to rotate said rotatable pump housing about the axis of said stationary screw to deliver said highly viscous fluid from said delivery nozzle.
A highly-viscous-fluid applying apparatus comprising:
- a fluid supply device operable to supply a highly viscous fluid;
- a delivery nozzle from which the highly viscous fluid is delivered;
- a screw pump disposed between said fluid supply device and said deliver nozzle, and including a stationary screw that is non-rotatable, and a rotatable pump housing having a screw chamber of a circular share in transverse cross section, said rotatable pump housing accommodating said stationary screw substantially fluid-tightly and being rotatable about an axis of said stationary screw, said screw pump being operable to deliver the highly viscous fluid received from said fluid supply device, from said delivery nozzle, by rotation of said rotatable pump housing about the axis of said stationary screw;
- a pump control device including a pump drive device operable to rotate said rotatable pump housing about the axis of said stationary screw, to deliver said highly viscous fluid from said delivery nozzle;
- and
- a machine frame,
- wherein said fluid supply device includes a stationary container for accommodating a mass of the highly viscous fluid, said stationary container including a supply portion having an opening from which the highly viscous fluid is supplied, said stationary screw being fixed to and coaxial with said supply portion of said stationary container,
- and wherein said rotatable pump housing is held by the machine frame rotatably and axially immovably relative to said machine frame, and said stationary container is removably mounted on said machine frame, said stationary screw being fitted into said rotatable pump housing as said stationary container is mounted on the machine frame, and removed from the rotatable pump housing as the stationary container is removed from the machine frame.
