Sheet stock feeding applications often require more than simple start-and-stop motion. In many production environments, the material needs to be advanced by a specific distance so each cut, form, punch, or process step occurs at the correct location.
For applications where feed length needs to be controlled accurately, Sankyo Automation’s Indexing Drive with reducer provides a reliable mechanical solution.
Controlled Sheet Stock Feeding
In this application, the Indexing Drive has a 360° indexing period, creating a continuous drive that can be started or stopped at any desired position. This allows the feed rollers on the output side to advance sheet stock according to the required length.
Instead of being locked into one fixed feed pitch, the system can control material progression based on the rotating angle of the input shaft. This makes it well suited for applications where sheet length, part spacing, or process timing needs to be adjusted for the best material fit.
How the System Works
The Indexing Drive transfers controlled rotary motion to the feed rollers. As the input shaft rotates, the feed rollers advance the sheet stock forward. By controlling the rotating angle of the input shaft, the system controls how far the material progresses.
This allows manufacturers to fine-tune the feed pitch and advance the sheet stock to the proper position for the next operation.
Benefits of Variable Feed Pitch
Variable feed pitch is especially useful when manufacturers need to optimize material usage, maintain accurate part spacing, or adjust feed length for different production requirements.
Key benefits include:
Controlled progression of sheet stock
Adjustable feed length based on input shaft rotation
Accurate material positioning
Efficient use of sheet material
Smooth integration with feed rollers
Reliable mechanical control for production lines
Ideal for Sheet Stock Processing
This configuration is useful in applications where sheet stock is being fed into downstream processes such as cutting, punching, forming, stamping, or other sequential operations.
Because the feed amount is controlled by the rotating angle of the input shaft, the system gives manufacturers a dependable way to manage material movement without relying only on fixed-pitch feeding.
