AI Technical Summary

Technical Problem

Conventional horizontal pillow packaging machines require workers to lift heavy rolls of packaging film to a high position for attachment, making the work difficult and burdensome.

Method used

The first tension mechanism is repositioned to the side and above the former, with a vertically displaceable cushion roller, and includes a guide roller above the rolls, a tension case with an encoder roller and registration mark sensor, and a cushion roller actuator for easier film attachment and control.

Benefits of technology

This configuration lowers the attachment point of the rolls, reduces worker burden, and enhances work efficiency by facilitating easier film handling and speed control.

Abstract

To make efficient the operation to mount original fabric on an original fabric support part by facilitating the operation and lightening the burden on an operator.SOLUTION: A first tension mechanism 24 which has a cushion roller 46 disposed in a vertically displaceable state is disposed above a former 20 by an original fabric support part 22, and can have original fabric 14 located lower by the installation space of the first tension mechanism as compared with a case where the first tension mechanism having a horizontally displaceable cushion roller applying tension to a packaging film 10 fed from the original fabric 14 supported by the original fabric support part 22 as usual is disposed below the original fabric 14 and above the former 20.SELECTED DRAWING: Figure 1
