Abstract
Generally, the present invention relates to a fluid container in a unit of a printing machine, comprising a device filling a fluid container with fluid, the device being mounted on a carriage so as to be movable to and fro in longitudinal direction of the fluid container, and comprising a device monitoring the fluid level in the fluid container by means of sensors being fastened to the carriage.
Claims14
An ink fountain for the inking unit of a rotary printing press said ink fountain comprising:
- a filling device for filling said ink fountain with ink;
- a carriage for mounting said filling device;
- an elongated beam;
- mounting structure for mounting said carriage on said elongated beam to permit said carriage to move along said elongated beam;
- said carriage being movably mounted on said elongated beam with said mounting structure;
- said filling device being mounted on said carriage;
- a monitoring device for monitoring the ink level in said ink fountain, said monitoring device comprising:
- at least one sensor;
- said at least one sensor having a sensing structure to determine the ink level in said ink fountain;
- said at least one sensor being firmly attached to and being movable with said carriage to move along with said filling device;
- and
- said at least one sensor being connected to said filling device to actuate said filling device to supply ink to said ink fountain upon said at least one sensor sensing an ink level below a predetermined ink level;
- said rotary printing press comprising a plurality of rollers;
- said plurality of rollers comprising:
- a plurality of ink application rollers;
- a plate cylinder;
- a blanket cylinder;
- and
- a sheet drum;
- said ink fountain comprising:
- an ink fountain roller;
- an ink metering device for producing an ink profile on said ink fountain roller;
- and
- an ink reservoir to supply ink to said ink metering device;
- said filling device having a first direction of travel along said elongated beam;
- said at least one sensor being disposed to move with said filling device in said first direction of travel and being disposed to precede said filling device upon movement of said filling device in said first direction of travel;
- said monitoring device comprising at least two sensors;
- said at least two sensors being a first sensor and a second sensor;
- said second sensor of said at least two sensors being firmly attached to said carriage;
- and
- said second sensor being disposed to move with said filling device in said first direction of travel and being disposed to follow said filling device upon movement of said filling device in said first direction of travel.
