In the field of packaging equipment, the changeover is to adjust the machine to suit different bags. Change over means that the machine is offline rather than production, which is equivalent to the loss of funds. The easier and faster the change over, the better, especially for companies that need to package their products in different bags.

Here are the simple steps required to adjust an automatic pouch machine for different bags:

Step 1: Adjust bag grippers

There are two ways to choose:

1. Automatically: The machine operator changes a setting on the Human Machine Interface (HMI) that that adjusts the bag grippers to the width of the new pouches. Bag parameters can be saved for future use.

2. Manually: Adjusting the bag grippers to the width of the new pouches by Hand wheel.

Step 2: Adjust bag feed guides

The guides that feed the pouches into the machine need to be adjusted to accommodate the new bag width. This is done by turning the magazine Hand wheel either clockwise (decrease the width) or counterclockwise (increase the width).

Step 3: Adjust bag feeding roller (Just for zipper bag)

Sometimes a third adjustment is necessary if the bag length differs from a previous setting. This involves moving the bag feeding roller to a new position. The bag roller is the mechanism by which bags are fed into the machine and must be moved based upon bag length.

Step 4: Test your changes

Do a test run to make sure the changeover was successful.
