Claim 1
Independent Claim
318 words
An apparatus for matching the register marks an punching U-shaped holes for a press plate, said apparatus comprising: a press plate material loading table positioned on a base for loading a press material, its lower edge being positioned on said loading table, a pin hole positioning mechanism for supporting the lower edge of said press plate material to position said press plate material at a predetermined pin hole location from said lower edge, a press plate material centering mechanism for centering the center of said press plate material in the horizontal material at a predetermined pin hole location from said lower edge, a press plate material centering mechanism for centering the center of said press plate material in the horizontal direction on said press plate material loading table, register mark location reading means overhung from the upper edge of said press plate material loading table so as to be able to be moved and finely adjusted in the horizontal and vertical directions and locked at a desired location, for reading register marks on said press plate material, a press plate material horizontal and vertical feed mechanism with a horizontal fine adjustment mechanism and a vertical fine adjustment mechanism for adjusting said press plate material in the horizontal and vertical direction, respectively, to match location of register marks of said press plate material, a press plate locking means, for vacuum contacting and releasing said press plate material through a plurality of air suction holes provided on said press plate material loading table, an automatic U-shaped hole punching mechanism with one to six parts of punches which have different pitches, for punching a pair or two pairs of U-shaped holes of predetermined pitches on said press plate material automatically, and an operation device, connected electrically to said horizontal fine adjustment mechanism, said vertical fine adjustment mechanism and said automatic U-shaped hole punching mechanism, for controlling the operation of each mechanism.
Claim 2
Independent Claim
318 words
An apparatus for matching the register marks an punching U-shaped holes for a press plate, said apparatus comprising: a press plate material loading table positioned on a base for loading a press material, its lower edge being positioned on said loading table, a pin hole positioning mechanism for supporting the lower edge of said press plate material to position said press plate material at a predetermined pin hole location from said lower edge, a press plate material centering mechanism for centering the center of said press plate material in the horizontal material at a predetermined pin hole location from said lower edge, a press plate material centering mechanism for centering the center of said press plate material in the horizontal direction on said press plate material loading table, register mark location reading means overhung from the upper edge of said press plate material loading table so as to be able to be moved and finely adjusted in the horizontal and vertical directions and locked at a desired location, for reading register marks on said press plate material, a press plate material horizontal and vertical feed mechanism with a horizontal fine adjustment mechanism and a vertical fine adjustment mechanism for adjusting said press plate material in the horizontal and vertical direction, respectively, to match location of register marks of said press plate material, a press plate locking means, for vacuum contacting and releasing said press plate material through a plurality of air suction holes provided on said press plate material loading table, an automatic U-shaped hole punching mechanism with one to six parts of punches which have different pitches, for punching a pair or two pairs of U-shaped holes of predetermined pitches on said press plate material automatically, and an operation device, connected electrically to said horizontal fine adjustment mechanism, said vertical fine adjustment mechanism and said automatic U-shaped hole punching mechanism, for controlling the operation of each mechanism.
