  • Patent number: 8251775
    Abstract: A shaft motion detection mechanism capable of detecting the displacement of a rotating body in a direction along a rotational axis and the rotation of the rotating body is disclosed. In one embodiment, the invention is a conditioner head capable of detecting the displacement of a polishing disk in a direction along a rotational axis and the rotation of the polishing disk. A shaft rotates around a rotational axis and a cylindrical shaft is attached to the shaft so that the shaft can be displaced along the rotational axis. A first plurality of projections are formed on the surface of the shaft so as to be aligned in a circumferential direction. A second projection is formed around the entire circumference on the surface of the shaft. Proximity sensors arranged around the rotational axis sense the first and second projections to detect displacement and rotation of the rotating body.

  • Patent number: 7028616
    Abstract: In an ink supply amount control method for a printing press, the number of ink fountain keys whose gap amount with respect to an ink fountain roller falls within a predetermined range is counted. On the basis of the count value, the swing operation of an ink ductor roller which is arranged in an ink supply path and swings in synchronism with rotation of the printing press is controlled. Ink is supplied from the gap between the plurality of ink fountain keys and the ink fountain roller to the ink supply path in accordance with rotation of the ink fountain roller at the time of printing. The ink is supplied to a printing plate attached to a plate cylinder through the ink supply path by the swing operation of the ink ductor roller. An ink supply amount control apparatus and a printing press are also disclosed.

  • Patent number: 6915737
    Abstract: In an ink supply amount control method for a printing press, ink is supplied from the gap between a plurality of ink fountain keys and an ink fountain roller to an ink supply path in accordance with rotation of the ink fountain roller. The swing operation of an ink ductor roller is temporarily stopped. When the swing operation should intermittently be stopped, the operation of the ink fountain key or the ink fountain roller is controlled to control the ink supply amount to the ink ductor roller. Ink in a corrected amount is supplied to a printing plate attached to a plate cylinder through the ink supply path by the swing operation of the ink ductor roller. An ink supply amount control apparatus is also disclosed.

  • Patent number: 6912954
    Abstract: A method and apparatus are disclosed for numerically adjusting the home position of a plurality of ink fountain blades in a printing press. In the printing press, apparatus is provided for adjusting the ink feed amount to be supplied from an ink fountain into an ink fountain roller by adjusting the position of these ink fountain blades, supplying ink to a printing plate through the ink fountain roller, and printing the ink supplied on the printing plate on a printing sheet. The present method and apparatus first position each ink fountain blade at its home position, then set the indication of the position of each ink fountain blade at a predetermined value. Each ink fountain blade is then adjusted by the same amount while observing the indication of the position of each ink fountain blade. Finally, the position of each ink fountain blade as so adjusted is stored as a new home position.

  • Patent number: 6402404
    Abstract: A sheet supply control apparatus for a printing press includes a sucker, a memory, a sheet detector, a counter, and a CPU. The sucker supplies sheets to a printing unit one by one with a predetermined supply interval. A count of sheets to be supplied to the printing unit is set in the memory. The sheet detector detects the sheets supplied from the sucker. The counter counts sheets supplied from the sucker after the sheet detector detects a first sheet. The CPU controls supply operation of the sucker, on the basis of the count preset in the memory and the count of the counter, such that the count of sheets supplied from the sucker coincides with the count preset in the memory. A sheet supply control method for a printing press is also disclosed.
