A containment force apparatus and method a containment force apparatus for measuring containment force on a load, the apparatus comprising a first element configured to contact the load; a second element configured to engage at least a portion of a packaging material on the load and move between a first position associated with the first element to a second position perpendicular to the first position and spaced from the first element a measured distance; an actuator configured to urge the second element to move between the first position and the second position; and a force sensor configured to measure a force exerted on one of the first element or the second element.

An apparatus and method for wrapping a palletized load are provided. The apparatus preferably includes a film dispenser for dispensing a film web, at least one guide rollers configured to engage the width of the film web, and at least one roping element. The at least one roping element may be a cable rolling roper configured to roll a portion of the film web into a rolled cable of film. The apparatus may also include means for providing relative rotation between the load and the dispenser to wrap a roped portion of the film web around a base of the load/top portion of a pallet supporting the load.

A wrapping machine includes a frame for supporting a wrapping unit arranged to wrap a load with a film of plastic material, and a covering apparatus arranged to supply a covering sheet to be positioned on top of the load. The covering apparatus includes a reel of covering sheet and gripping assembly movable along an unwinding direction and arranged to grasp and unwind from the reel and place above the load the covering sheet. The covering apparatus includes a supporting structure connected to an upper portion of the frame and slidably supporting the gripping assembly, and a supplying unit supporting a respective reel of covering sheet and reversibly coupled to the supporting structure so as to be removable and replaceable with another supplying unit, in particular in case of depletion of the reel of covering sheet.

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.

An improved silo bag extractor that can collect grain or other flowable materials contained therein. As the extractor empties the silo bag's contents into an accompanying grain cart, it simultaneously performs differentiated cuts on the bag, effectively dividing it in two bands of plastic that are directed to the left and right sides of the machine, where they wind tightly around roll-up assemblies equipped with consumable rigid plastic cores. On terminating grain extraction, the used plastic sheet takes the form of two very dense bales that can each weigh 100 kilos or more depending on the original size of the bag. These bales are then released from the machine automatically, proffering several advantages: not having to manually collect large swaths of plastic, not having to rewind the plastic on a second contraption and accomplishing lesser compaction in the process, easier storing and handling, and lower transportation costs to recycling centers.

A method, apparatus and program product may utilize various approaches for adapting stretch wrapping to accommodate lower quality packaging materials such as packaging materials including recycled content, including heating a web of packaging material prior to or during pre-stretching, utilizing multiple pre-stretch zones and/or reducing surface adhesion of one or more pre-stretch rollers used by a load wrapping apparatus.

The present invention provides a wrapping robot with enhanced safety and reliability, the wrapping robot being able to prevent a safety accident that occurs when a worker or another object hits against a handle protruding outward from a robot body while the robot revolving around a product to perform wrapping by biasing the handle toward the product to be wrapped; and being able to improve reliability of wrapping by stopping operation of the wrapping robot when a wrap is loosened or cut during wrapping, using a sensor that senses loosening or cutting of a wrap.

A wrapping machine with a rotary platform to wrap products with at least one band of wrapping material has a base, a rotary platform, which defines a support surface for at least one product and is mounted so as to rotate around a rotation axis, and a support slide, which is configured to receive and hold a spool of the band of wrapping material and is movable along a guide upright, which is mounted so as to rotate around the rotation axis with a rotation direction that is contrary to a rotation direction of the rotary platform.

The present application relates to a film wrapping equipment. The film wrapping equipment includes: a film wrapping assembly including two film wrapping rollers arranged opposite to each other in a first direction, and a film wrapping channel for a product to pass through formed between the two film wrapping rollers; a film pulling assembly arranged on one side of the film wrapping assembly in the first direction; a product loading assembly used to clamp the product and drive the product to pass through the film wrapping channel; and a strip cutting assembly used to cut off material strips located on two sides of the two film wrapping rollers in the first direction.

A stretch film dispenser includes a frame. The frame has a top seat and a bottom seat. The top seat and the bottom seat are jointly equipped with a film mounting unit and a film dispensing unit. The film dispensing unit includes a first roller and a second roller. The first roller and the second roller have a strip hole. The strip hole is located between the first roller and the second roller. Through the strip hole of the first roller and the second roller, the front end of a film can pass through the strip hole between the first roller and the second roller easily and quickly, and the film is pulled out along the direction of the first roller, thereby achieving the effect of easy and convenient installation of the film.
