Abstract
Various embodiments of the present disclosure provide a press-type strapping machine configured to strap a load when both the height of the load falls within a target height range and the compressive force applied to the load falls within a target compressive force range.
Claims19
A strapping machine comprising:
- a frame;
- a top platen supported by the frame;
- a load supporter below the top platen;
- a top-platen actuator operably connected to the top platen to move the top platen toward and away from the load supporter;
- a strapping head;
- a distance sensor;
- and
- a controller configured to:
- control the top-platen actuator to move the top platen toward the load supporter and a load positioned on the load supporter;
- as the top platen moves toward the load supporter and the load, determine and monitor a distance between the top platen and the load supporter based on feedback from the distance sensor;
- and
- responsive to determining that both:
- (1) the distance between the top platen and the load supporter is within a target distance range;
- and (2) a compressive force the top platen applies to the load is within a target compressive force range, control the strapping head to strap the load.

A method of operating a strapping machine, the method comprising:
- moving a top platen downward toward a load supporter on which a load is positioned;
- as the top platen moves downward toward the load supporter and the load, determining a distance between the top platen and the load supporter based on feedback from a distance sensor;
- and
- responsive to determining that both:
- (1) the distance between the top platen and the load supporter is within a target distance range;
- and (2) a compressive force the top platen applies to the load is within a target compressive force range, strapping the load by a strapping head.
