RETREATING OPERATION CONTROL METHOD FOR PLANER TABLE FOR SPINDLELESS CUTTABLE VENEER LATHE AND SPINDLELESS CUTTABLE VENEER LATHE

摘要

PROBLEM TO BE SOLVED: To prevent the deviation of the cutting center of a log or damage to a planer table even if a finally cut log remains at the edge of a cutting blade of a veneer lathe after cutting operation of one log is completed, by controlling the retreating distance of a planer table such that a log being supplied next does not collide with the remaining log or even if a collision cannot be avoided, they are only brought into a slight contact with each other. ;SOLUTION: A detector 41 is provided on a planer table 11 for detecting whether or not a finally cut log remains at the edge of a cutting blade 19. In a case where it is detected that a finally cut log so remains by the detector 41, it is controlled such that the planer table 11 is retreated to a position which is spaced away a distance equal to a sum of a distance L equal to a maximum radius R of a log being supplied and a distance equal to a diameter D of the finally cut log. In a case where it is detected that no finally cut log remains, it is controlled such that the planer table is retreated to a position which is spaced away a distance L corresponding to a maximum radius of a log being supplied.;COPYRIGHT: (C)1999,JPO
