Title:
REVERSE ROTATION PREVENTIVE ELECTRONIC CAM CURVE GENERATING METHOD BASED ON ELECTRONIC CAM TYPE ROTARY CUTTER CONTROL, AND CONTROL DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2004/060597
Kind Code:
A1
Abstract:
The subject of the invention is to provide a reverse rotation preventive electronic cam curve generating method based on electronic cam type rotary cutter control for preventing reverse rotation of a cutter. The reverse rotation preventive electronic cam curve generating method based on electronic cam type rotary cutter control is such that from the settings of the rotor diameter (r) of a rotary cutter (5), the number of cutting blades (M) disposed equally spaced in a rotor, synchronous speed coefficients (β1, β2) for adjusting the synchronous speed during cutting, and synchronous angles (Ѳ1, Ѳ2), a limit cut length (Ljag) by which an electronic cam curve passing through the points of acceleration 0 and speed 0 is found is computed in advance, and an electronic cam curve parameter setter (28) is provided so that when a comparison therewith of a set cut length (Lset) for work set by the operator detects that the set cut length (Lset) is greater, an electronic cam curve pattern is produced for preventing reverse rotation.
