Introduction

Converting ToolboxIntroduction

The application SIMOTION Rotary Knife was developed with theobjective to address many of the known cross cutter applicationsusing just one application software.

When required, the application can be configured or also changedas a result of openness.

Using the SIMOTION control platform the application SIMOTIONRotary Knife allows to realize cross cutters to be implemented forthe widest range of applications, e.g. foil, film, paper, currogatedetc.

Works in combination with:SIMOTION Axis Function Block

Introduction

Converting ToolboxScope of Functionality

The goal of the „Rotary Knife“• The principal requirement of the rotary knife is to respect the

synchronism during the cut the moving web by the knife or bythe tool

• The standard „Rotary Knife“ used to divideinto pieces a moving web

• Special tools for• Perforation• Welding• Double cut

StartSyncAngle [°] Start point of the synchronous range referred to 0°.From this position onwards, the cutting knife must move in synchronism with the material to be cut.

EndSyncAngle [°] End point of the synchronous range referred to 0°.From this point onwards, the knife no longer has to move in synchronism with the material to be cut, and dependingon the requirement, can be accelerated or decelerated to adapt the format

LINEARThis selection defines a motion profile with constant acceleration..

POLY_5This selection defines a fifth order polynomial as basis for the motion profile..

JERKThis selection defines a profile with constant acceleration and jerk limiting.Jerk limiting is specified using parameter jerkPhase1 / jerkPhase.The parameters are only evaluated in this profile.

The following cam profiles can be selected:

SINUSThis selection defines a sinus as basis for the motion profile..

Introduction


State Description

ERROR (0) FBRotaryKnife has detected a fault and has brought the rotary knife axis into a safe state. Thefault is still present and can be evaluated by the user.The rotating knife has been stopped and is in the DISABLE mode. .

DISABLE (1) FBRotaryKnife is ready for use, but is still in the safe operating state.All of the pending faults have been successfully acknowledged. The rotating knife is in the stateafter a reset, deactivated and stopped

STARTPOSITION (2) The rotating knife is moving or is already located at the START POSITION and is ready to besynchronized to the material web. The axis waits in the START POSITION operating mode

AUTOMATIC (3) The rotating knife has been synchronized to the material web and is cutting the material accordingto the specifications

MANUAL (4) The rotating knife is the manual mode; the user can manually move the axis.The axis waits in the MANUAL operating mode.

SINGLE_CUT (5) The rotating knife is ready for a single cut.

SAMPLE_CUT (6) The rotating knife is ready to cut a series of test pieces.(Number and length of pieces has to be entered in SampleBuffer before starting!)

Introduction


• Parameterization instead of programming• Open Source• Linear cut curve with adaptable over speed• Different Profiles: Const. acceleration, jerk limitation,

polynomial 5th, Sinus and polynomial 6th

• Print mark correction with settable correction speed:• Correction movement in the format range• Shift register

• Multi knife system• Settable Standby position of the knife• Predefined start and stop behavior• Dynamic change of the cut length on the fly• Operating mode manager• Single cut and sample cut (cut program) functionality.

Introduction


Additional functionality in version 3.0:

• Pre control of acceleration torque• Pre control of cutting torque• Pre control of DC-Link voltage

(only by using ALM and capacitors connected to DC-Link!)• Increasing the functionality of CAM calculation

- new profiles in format section: POLY_6, SINUS- profiles in synchronous section: CONST (conform to V2.0!)

LINEAR (“kick out”)- pendulum cut possible when

formatlength > 4 * knifecircumference• Interrupt / Continue Production• Vmax-Calculation

- calculation of maximal web speed at a certain formatlength- calculation of performance curves
