Dynamic adjustment of wrap force parameter responsive to monitored wrap force and/or for film break reduction

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.

The present invention relates to a film wrapping machine for a product packing device using a stretch film, including a frame having vertical bars extending upward and spaced apart from each other, a film clamping unit including a pair of suction pads which are moved in a direction of being spaced apart from each other in a state of adsorbing the stretch film so that a front end portion of the stretch film supplied from a film supply device is opened, and a plurality of clamps configured to grip the front end portion of the stretch film opened by the suction pads, receive the stretch film whose upper end is cut and bonded by the film supply device in a wrinkled state, and process the stretch film to be covered on a product in a process of lowering the vertical bars, and a controller which controls operation of the film clamping unit and the film supply device.

APPARATUS FOR WRAPPING A FILM AROUND AN OBJECT AND RELATED METHOD
20220315257 · 2022-10-06 · ·

The present invention refers to an apparatus and a method for wrapping a film around an object. The apparatus includes a device capable of being electrostatically charged and capable of transmitting the electrostatic charge to the portion of film that comes out of the carriage. In this way, the fixing of the leading end flap of the film around the object to be wrapped is thus facilitated. In fact, the leading end flap of the film, as soon as it is dispensed, remains stretched out of the carriage and, as soon as it meets the object to be wrapped, it immediately fastens to it due to the attraction force. The rotation is then activated to wrap the film around the object. The apparatus is simple to make, cheap, and highly efficient.

Wrapping machine
