Abstract
A printing machine includes: a printing plate attached to a plate cylinder; a blanket configured to transfer ink from the printing plate to a printed material; a blanket wheel configured to rotate the blanket; and at least one of a distance sensor or a temperature sensor. The distance sensor is provided in the blanket wheel and configured to measure a distance of the printing plate to the blanket wheel, and the temperature sensor is provided in the blanket wheel and configured to measure a temperature of the printing plate.
Claims12
A printing machine comprising:
- a printing plate attached to a plate cylinder;
- a blanket configured to transfer ink from the printing plate to a printed material;
- a blanket wheel configured to rotate the blanket;
- and
- at least one of a distance sensor or a temperature sensor,
- the distance sensor being provided in the blanket wheel and configured to measure a distance of the printing plate to the blanket wheel, and
- the temperature sensor being provided in the blanket wheel and configured to measure a temperature of the printing plate.
A method of monitoring a state of a printing machine including:
- a printing plate attached to a plate cylinder;
- a blanket configured to transfer ink from the printing plate to a printed material;
- and
- a blanket wheel configured to rotate the blanket,
- the method comprising:
- acquiring at least one of a result of measuring a distance of the printing plate to the blanket wheel by a distance sensor provided in the blanket wheel, or a result of measuring a temperature of the printing plate by a temperature sensor provided in the blanket wheel.
A printing machine comprising:
- a mandrel configured to hold a printed material;
- a mandrel wheel configured to rotate the mandrel;
- and
- a mandrel distance sensor provided outside the mandrel wheel and configured to measure a distance to the mandrel, and
- a processor,
- wherein the distance measured by the mandrel distance sensor indicates a position of the mandrel in a radial direction of the mandrel wheel, and
- the processor is configured to control the mandrel distance sensor to perform measurement when operation of the printing machine is stopped.
A method of monitoring a state of a printing machine including:
- a mandrel configured to hold a printed material;
- a mandrel wheel configured to rotate the mandrel;
- and
- a mandrel distance sensor provided outside the mandrel wheel and configured to measure a distance to the mandrel,
- wherein the distance measured by the mandrel distance sensor indicates a position of the mandrel in a radial direction of the mandrel wheel,
- the method comprising:
- acquiring a result of measuring the distance to the mandrel by the mandrel distance sensor when operation of the printing mandrel is stopped.
