Patent number: 4798110Abstract: A method for positioning tools comprises a first process for moving all tools into a stand-by reach and a second process for moving tools into a positioning reach, and the second process comprises steps of moving a tool onto an origin and moving the tool from the origin by a distance equal to a desired distance between the tool and a following tool. An apparatus for positioning tools is provided with a single signal generator rotated by a rotating shaft for moving shifters, by which the tools are moved in the positioning and stand-by reaches.Type: GrantFiled: November 4, 1981Date of Patent: January 17, 1989Assignee: Rengo Co., Ltd.Inventors: Masateru Tokuno, Tetsuya Sawata, Yasuharu Mori

Patent number: 4737846Abstract: A device for detecting any defects in single faced corrugated fiberboard while it is running. A light is irradiated to the corrugated surface of the fiberboard and the striped image is scanned by an image pick-up unit and the picture signal is converted to binary-coded signal to discriminate the number of stripes or corrugations. The number is counted by a counter and compared with a normal number by a microcoputer. If there is too large a difference between them, the scanned part is judged as defective. This device can detect any defects in a running web at a sufficiently high speed to follow the line speed of a corrugating machine.Type: GrantFiled: May 28, 1987Date of Patent: April 12, 1988Assignee: Rengo Co., Ltd.Inventors: Masateru Tokuno, Tetsuya Sawada, Yasuharu Mori, Ikuo Yoshimoto

Patent number: 4696212Abstract: An improved rotary cutter for a web material is proposed. It has a pair of rolls adapted to rotate synchronously in opposite directions and an axially elongated knife secured to each roll to extend axially. A plurality of rolling bodies are arranged around each roll to bear the shock upon cutting. Different means for preventing the knives from hitting the rolling bodies are proposed. This arrangement prevents the rolls from warping due to shock upon cutting and allows the use of rolls having a smaller diameter.Type: GrantFiled: June 16, 1986Date of Patent: September 29, 1987Assignee: Rengo Co., Ltd.Inventors: Masateru Tokuno, Tetsuya Sawada, Yasuharu Mori

Patent number: 4658723Abstract: A color printing machine having a plurality of printing units includes a plate cylinder and an impression cylinder. A web length adjusting unit is arranged between each pair of adjacent printing units so as to adjust the length of web existing between the printing units to be equal to the printing length multiplied by an integer.Type: GrantFiled: February 18, 1986Date of Patent: April 21, 1987Assignee: Rengo Co., Ltd.Inventors: Masateru Tokuno, Tetsuya Sawada, Yasuharu Mori

Patent number: 4600841Abstract: Mark detector for detecting marks on a running web distinguished from any printed letter or pattern or any printing smudge. The width of mark segments and the distance between them are determined and, if they are within preset ranges, a mark detection signal is given. A delayed signal generator and a false signal generator are provided.Type: GrantFiled: July 19, 1983Date of Patent: July 15, 1986Assignee: Rengo Co., Ltd.Inventors: Masateru Tokuno, Yasuharu Mori

Patent number: 4592278Abstract: An improved printing apparatus has printing units, a pair of feed rolls, a pair of pull rolls, a speed adjusting unit having a pair of rolls, and a control unit. The speed adjusting unit reciprocates linearly to advance and retreat the web in the printing units. While the web is being printed, the feed and pull rolls are stopped. While it is not being printed, they are driven to feed the web for a distance equal to one printing length. The speed adjusting unit is driven so as to move at a speed equal to half the peripheral speed of the plate cylinder while the web is being printed.Type: GrantFiled: December 10, 1984Date of Patent: June 3, 1986Assignee: Rengo Co., Ltd.Inventors: Masateru Tokuno, Tetsuya Sawada, Yasuharu Mori

Patent number: 4580086Abstract: Tools to be positioned all at once are moved from a stand-by reach toward a positioning reach by means of a rotatable shaft, and respectively positioned at their desired positions in the positioning reach after passing an origin located at a border line between the stand-by and positioning reaches. Central computer controls count pulse signals transmitted from a pulse generator synchronously rotated by the rotatable shaft, and compensate set values for the desired positions for the distance over which each tool has been moved in the stand-by reach.Type: GrantFiled: March 14, 1984Date of Patent: April 1, 1986Assignee: Rengo Co., Ltd.Inventors: Masateru Tokuno, Tetsuya Sawada, Yasuharu Mori
