Introduction

Converting ToolboxIntroduction

The application SIMOTION Rotary Knife was developed with the objective 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 SIMOTION Rotary Knife allows to realize cross cutters to be implemented for the widest range of applications, e.g. foil, film, paper, currogatedetc.

Works in combination with: SIMOTION Line Axis

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 by the tool

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.

Introduction


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!)

SAMPLE_CUT (6)

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

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

MANUAL (4)

The rotating knife has been synchronized to the material web and is cutting the material according to the specifications

AUTOMATIC (3)

The rotating knife is moving or is already located at the START POSITION and is ready to be synchronized to the material web. The axis waits in the START POSITION operating mode

STARTPOSITION (2)

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 state after a reset, deactivated and stopped

DISABLE (1)

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

Introduction


Parameterization instead of programming

Following properties can be covered the function „Rotary Knife“:

Linear cut curve with adaptable over speed In the cut domain the knife and the web have the same velocity

Polynomial cam Overshoot can be avoided

Print mark correction with settable correction speed Die correction occurs out of the synchronous domain

Multi knife system The Rotary Knife-FB can be used also with multi knife drum

Settable Standby position of the knife Can be set with a parameter from the user

Predefined start and stop behavior In order to start and stop the knife without jerk

Dynamic change of the cut length Cam profile online adjusted by print mark and by format change
