Abstract: A method, apparatus and program product monitor a wrap force during a wrap cycle to dynamically control the dispense rate of a packaging material dispenser to meet a desired containment force to be applied to a load. A conversion may be performed between wrap force and containment force for the monitored wrap force or a containment force parameter to facilitate the performance of a comparison between the monitored wrap force and a containment force parameter associated with the desired containment force to be applied to the load. A wrap force parameter may also be dynamically adjusted, and in some instances, the dynamic adjustment may be responsive to monitored wrap force, and may be used to meet a load containment force requirement for a load. In other instances, the dynamic adjustment may be responsive to monitored packaging material breaks to reduce the occurrence of packaging material breaks.

Abstract: An apparatus for wrapping a load may include a film dispenser for dispensing a film web including a film dispensing drive. The apparatus may also include a rotational drive system for providing relative rotation between the load and the dispenser during a wrapping cycle. The apparatus may further include a controller configured to operatively couple the film dispensing drive and the rotational drive system such that, for any portion of a revolution of the film dispenser relative to the load during the wrapping cycle, the film dispenser dispenses a selected length of the film web corresponding to the portion of the revolution.

Abstract: A method, apparatus and program product perform automatic load profiling to optimize a wrapping operation performed with a stretch wrapping machine. Automatic load profiling may be performed, for example, to determine a density parameter for a load that is indicative of load stability such that one or more control parameters may be configured for a wrapping operation based upon the density parameter. Automatic load profiling may also be performed, for example, to detect a load with a nonstandard top layer, e.g., a load with a top or slip sheet, a load with an easily deformable top layer, a load with a ragged top surface topography and/or a load with an inboard portion, such that a top layer containment operation may be activated during wrapping to optimize containment for the load.

Abstract: The present invention relates to the field of electron beam machines, such as linear straight through machines, and methods used for therapeutic uses. More particularly, the present invention relates to electron beam machines that incorporate a rotary coupling system to easily attach and manually or automatically rotate field defining members such as applicators and/or shields to the electron beam machines. The rotary coupling systems also incorporate functionality to automatically detect collisions involving the electron beam machines such as between an electron beam machine and other equipment or a patient.

Abstract: The present invention relates to linear, straight through electron beam machines that incorporate a rotary coupling system to easily attach and manually or automatically rotate field defining members such as applicators and/or shields to the electron beam machines. The rotary coupling systems also incorporate functionality for using different kinds of optical signals to automatically provide illumination, reference mark projection, and/or distance detection. The optical signals generated downstream from heavy collimator components and are transmitted along the central axis of the field defining elements so that function and accuracy are maintained as the components rotate.

Abstract: A method, apparatus and program product may determine load stability for a load to be wrapped based upon sensing the response or reaction of the load to a disturbance applied to the load, e.g., through intentionally moving, shaking, tilting, pushing, impacting or otherwise applying an input force to the load and sensing the response using one or more sensors. The sensed response may then be used to determine a load stability parameter that may be used in the control of a load wrapping apparatus when wrapping the load.

Abstract: An automatic roll change system for a stretch wrapping machine may include multiple mechanically-actuated load stations capable of being actuated by a common actuator assembly, as well as pivotable support members for use in positioning packaging material in a tortuous path for loading into a packaging material dispenser.

Abstract: A wrapping apparatus and method utilize a controlled intervention to vary a dispense rate relative to a predicted dispense rate calculated based upon a predicted demand for packaging material.

Abstract: The present invention provides improved methods and apparatus that use machine vision techniques to rapidly and automatically guide objects into desired docking configurations. The present invention is based at least in part upon using multi-depth, rotationally symmetric targets that are observed from two or more observation perspectives. By taking advantage of parallax effects associated with the multi-depth topography of the target, the apparent positions of target features in captured image information encodes position and angular alignment of the objects relative to each other in three dimensional space. The practice of the present invention provides a fast, accurate, reliable and automatic approach to achieve hard or soft docking configurations in the electron beam therapies as well as to implement real-time gating and tracking during the course of a treatment.

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.

Abstract: A wrapping apparatus and method recalculate the calculated location of at least one corner of a load at one or more elevations during relative rotation between the load and a packaging material dispenser to accommodate variations in length, width and/or offset of the load at different elevations.
