Abstract
A wrapping apparatus and method utilize a rotational data shift to a wrap speed model to offset system lag.
Claims32
An apparatus for wrapping a load with packaging material, the apparatus comprising:
- a packaging material dispenser for dispensing packaging material to the load;
- a rotational drive system configured to generate relative rotation between the packaging material dispenser and the load about a center of rotation;
- and
- a controller that controls a dispense rate of the packaging material dispenser during the relative rotation based upon a wrap speed model, wherein the controller offsets system lag by applying a rotational data shift to the wrap speed model to advance the wrap speed model to an earlier point in time or rotational position.

An apparatus for wrapping a load with packaging material, the apparatus comprising:
- a packaging material dispenser for dispensing packaging material to the load;
- a rotational drive system configured to generate relative rotation between the packaging material dispenser and the load about a center of rotation;
- and
- a controller that controls a dispense rate of the packaging material dispenser during the relative rotation based upon a predicted demand for packaging material at each of a plurality of rotational positions of the load about the center of rotation, wherein the controller further determines a corner contact angle about the center of rotation for a corner of the load and applies a rotational data shift to the corner contact angle to offset system lag, wherein the rotational data shift shifts the corner contact angle to an earlier rotational position.

An apparatus for wrapping a load with packaging material, the apparatus comprising:
- a packaging material dispenser for dispensing packaging material to the load;
- a rotational drive system configured to generate relative rotation between the packaging material dispenser and the load about a center of rotation;
- and
- a controller that controls a dispense rate of the packaging material dispenser during the relative rotation based upon a predicted demand for packaging material at each of a plurality of rotational positions of the load about the center of rotation, wherein the controller further determines a current rotational position of the load about the center of rotation and applies a rotational data shift to the current rotational position to offset system lag, wherein the rotational data shift shifts the current rotational position to a later rotational position.
1 more element
An apparatus for wrapping a load with packaging material, the apparatus comprising:
- a packaging material dispenser for dispensing packaging material to the load;
- a rotational drive system configured to generate relative rotation between the packaging material dispenser and the load about a center of rotation;
- and
- a controller that controls a dispense rate of the packaging material dispenser during the relative rotation based upon a wrap model, wherein the controller offsets system lag by applying a variable rotational data shift to the wrap model by varying the rotational data shift based at least in part upon a rate of relative rotation between the packaging material dispenser and the load.
1 more element
A program product, comprising:
- a computer readable medium;
- and
- program code configured upon execution by a controller in an apparatus that wraps a load with packaging material using a packaging material dispenser adapted for relative rotation with the load about a center of rotation, wherein the program code is configured to control a dispense rate of the packaging material dispenser during the relative rotation based upon a wrap speed model, and to offset system lag by applying a rotational data shift to the wrap speed model, wherein the program code determines a corner contact angle for a corner of the load, and applies the rotational shift by shifting the determined corner contact angle.
A method of wrapping a load with packaging material, the method comprising:
- controlling a dispense rate of a packaging material dispenser during relative rotation between the packaging material dispenser and the load about a center of rotation based on a wrap speed model;
- and
- offsetting system lag by applying a rotational data shift to the wrap speed model, wherein the rotational data shift aligns a phase of a profile of an actual dispense rate of the packaging material dispenser with that calculated using the wrap speed model.
