Abstract (en)
[origin: JPH06210594A] PURPOSE: To shorten a cutting process by descending a holdfast beam onto a plate- shaped article for the cutting, and sucessively lifting a cutting blade and the holdfast beam after the cutting in a state that the holdfast beam is lifted by a predetermined distance after the cutting blade has been lifted by a predetermined distance. CONSTITUTION: In a guillotine cutting machine where a holdfast beam 8 ascends and descends in interlocking with the ascending and descending motion of a cutting blade 7 supported by a gate-shaped frame for cutting an article 1 such as the stack of paper, cardboard and the like by the cutting blade 7 in a state that the article 1 is pressed by the holdfast beam 8 from its upper part, a photoelectric device-type sensor 14 is mounted within a range of opposite both end surfaces of the holdfast beam 8 under an effective surface 8a of the holdfast beam 8 contacted with the article 1, and a proximity switch 25 operating when an edge 7a of the cutting blade 7 takes a predetermined gap Z' to the effective surface 8a, is mounted on a surface at the cutting blade 7 side, of the holdfast beam 8. After the cutting, the cutting blade 7 is lifted to a position for operating the proximity switch 25 is operated, and then the holdfast beam 8 is lifted to a position for operating the sensor 14.
