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

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

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

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.

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

Packaging material (410) may be profiled to generate an incremental containment force per revolution (ICF) attribute that is represented by a function that is variable as a function of wrap force. Moreover, the performance of different packaging materials (410), e.g., in terms of speed or cost, may be compared for a particular load (406) through simulation of wrap operations based upon dimensions of the load (406) and a desired load containment force requirement for the load (406).

Abstract

A wrapping apparatus (1 00) and method utilize an effective circumference- based wrap speed model that dynamically controls the rate at which packaging material (108) is dispensed based on an effective circumference of a load (1 10) during relative rotation established between the load and a packaging material dispenser (1 06). The effective circumference of a load may be indicative of an effective consumption rate of the load, and may referto a dimension or size of a tangent circle (420) that is substantially centered at the center of rotation (408) of the load and substantially tangent to a line substantially extending between a first point (414) proximate to where the packaging material exits the dispenser and a second point (41 8) proximate to where the packaging material engages the load. The effective circumference of the load dynamically changes throughout the relative rotation of the load, and by controlling the dispense rate based at least in part on this dimension, fluctuations in tension in the packaging material may be reduced, often enabling containment force to be increased while reducing the risk of breakage in the packaging material.

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 during relative rotation established between the load and a packaging material dispenser. The locations of one or more corners on a load may be sensed or otherwise calculated, and when combined with a sensed or calculated rotational position of the load relative to a packaging material dispenser, the locations of the corners relative to the packaging material dispenser may be determined and utilized to control the dispense rate of the packaging material dispenser, e.g., by determining which corner is currently driving an effective consumption rate of the load and/or determining when to apply a controlled intervention to the load.

Abstract

A turntable assembly for a stretch wrapping machine comprises a frame, a hub rotatably mounted to the frame on a shaft, a turntable mounted to the hub, and a plurality of rollers rotatably mounted to the frame defining a generally horizontal supporting plane for the turntable. Each roller has an axis of rotation generally parallel to the supporting plane and generally passing through the turntable axis of rotation. The frame is constructed so as to elastically deform, upon a load being placed upon the turntable that results in the load not being evenly supported by the rollers, to permit the roller axis of rotation to tilt relative to the horizontal supporting plane while still passing through the turntable axis of rotation.
