Description

  The present invention relates to a cutting head control method capable of performing V-groove machining with a cutter blade having a set angle freely on a thick paperboard on a plotter board surface.

  V-groove machining by the cutter blade of the cutter head in a diagonal direction with respect to the thick paperboard on the plotter board surface is performed in a cutting mechanism in which the cutter blade is held by an oblique holder set at a certain angle and sliding. Yes. In this cutting mechanism, the left and right angles of the V-groove shape of the thick paperboard cannot be freely set, and one kind of V-groove machining can be performed.

  For example, according to Japanese Patent Application Laid-Open No. 11-221794, a pair of sub-holders 202 holding a cutter blade 201 is slid in the left-right diagonal Z direction of a pressing body 205 that is sandwiched by a center line 204 that passes through an axis 203 of a vertical axis. Support symmetrically in a movable manner. Then, the roller 206 supported by the pair of sub-holders 202 is movably inserted into a cam hole 208 that is long in the oblique Z direction provided symmetrically on the left and right of the holder 207 across the center line 204 passing through the axis 203 of the vertical axis. To do. In this way, the tip of the cutter blade 201 held by the pair of sub-holders 202 supported symmetrically so as to be slidable obliquely in the Z direction on the left and right of the pressing body 205 with the center line 204 passing through the axis 203 of the vertical axis interposed therebetween. , Toward the center line portion 204a below the pressing body 205 of the center line 204 passing through the axis 203 of the vertical axis to the inside of the thick paper 209 portion to which the pressing body 205 is pressed, and from the left and right toward the diagonal Z direction V Invade in a letter shape. Next, with the pressing body 205 pressed against the cardboard 209, the cutter head 200 is placed on the platen 210 with the tip of the cutter blade 201 in a V shape inside the cardboard 209 portion. The V-groove 211 is continuously formed inside the thick paper 209 by the cutter blade 201 that is relatively moved in the direction and gripped in the pair of sub-holders 202. In this way, only a single V-groove machining is performed with an oblique angle set by the pair of sub-holders 202, that is, a V-shaped groove opening angle. V-groove machining with a different V-shaped groove angle cannot be handled.

  In general, the V-groove control by the cutter blade of the cutter head in an oblique direction with respect to the thick paperboard on the plotter board surface is limited to a single V-groove control with a preset V-shaped groove angle. For this reason, there is a problem in that it cannot cope with other V-groove control of different V-shaped groove angles.

JP-A-11-221794
