Integrated Motion Control
Applications
Inline Bottle Filler with 1394 Motion Control
The inline bottle filler is typical of a motion control application generally referred to as a flying shear. This application is common to several industries such as filling, cutting, punching, stamping, forming, labeling, and printing. Flying shear applications require work to be performed on a material while the material is in motion. A flying shear control must accelerate from a stop to match the speed of the moving material at a specific position, and then maintain synchronization of both position and velocity while the work is performed. After the operation is completed, the tool decelerates to a stop and returns to the start or home position. When the correct point on the moving material approaches, the process is repeated. The motion of the flying shear occurs within a fixed distance which cannot be exceeded, so the control must accelerate, track the material while the operation is performed, and decelerate within this distance at the maximum machine throughput.
Rockwell Automation Solution
The Allen-Bradley 1394 Single Axis Motion Controller and brushless servo motor provide the capability necessary for a flying shear control, with the flexibility of a programmable motion controller and the low maintenance of brushless servo technology.
Advantages of a Servo System
- Motion automatically follows machine speed so no reprogramming is necessary if the speed of the system changes
- The operator interface capability of the 1394 Motion Controller allows quick set-up and change-over between different sizes and spacings
- Accurate, repeatable digital control produces high throughput with minimum waste
