Abstract
A wrapping apparatus and method utilize a corner rotation angle-based wrap control that controls the rate at which packaging material is dispensed based on the rotational position of one or more corners of the load determined during relative rotation established between the load and a packaging material dispenser.
Claims27
An apparatus for wrapping a load with packaging material, the apparatus comprising:
- a packaging material dispenser that dispenses packaging material to the load;
- a rotational drive system that generates relative rotation between the packaging material dispenser and the load about a center of rotation;
- an angle sensor that senses an angular relationship between the load and the packaging material dispenser about the center of rotation;
- and
- a controller coupled to the packaging material dispenser, the rotational drive system and the angle sensor and that controls a dispense rate of the packaging material dispenser during the relative rotation by calculating, during the relative rotation and using the angular relationship sensed by the angle sensor and a calculated location of at least one corner of the load within a plane perpendicular to the center of rotation, a rotation angle that is about the center of rotation and that is for the at least one corner of the load.

A method of wrapping a load with packaging material, the method comprising:
- providing relative rotation between a load and a packaging material dispenser about a center of rotation to dispense packaging material to the load;
- sensing with an angle sensor an angular relationship between the load and the packaging material dispenser about the center of rotation;
- and
- controlling a dispense rate of the packaging material dispenser during the relative rotation by calculating, during the relative rotation and using the angular relationship sensed by the angle sensor and a calculated location of at least one corner of the load within a plane perpendicular to the center of rotation, a rotation angle that is about the center of rotation and that is for the at least one corner of the load.
