A control system for a wrapping apparatus may include a packaging material dispenser configured to dispense packaging material for wrapping a load. The control system may also include at least one sensor assembly configured to generate a signal based on instantaneous demand for packaging material at the load. The control system may further include a controller configured to control operation of the packaging material dispenser based at least in part on the signal.

Control of a wrapping apparatus is facilitated by enabling an operator to input a load containment force requirement and/or a minimum number of layers of packaging material to be applied to a load, with a wrap control system automatically determining wrap force and other parameters required to meet user input requirements and/or parameters to minimize the expertise required of an operator and to provide more consistent and reliable wrapping of loads. In addition, a wrapping apparatus may be controlled to apply at least a minimum number of layers of packaging material to a load throughout a contiguous region thereof.

Various embodiments of the present disclosure provide a wrapping machine that includes an improved cut, clamp, and seam system configured to, after film drawn from a film roll has been wrapped around an object, cut the film from the film roll, hold the now-leading end of the film of the film roll, and attach the now-trailing end of the film wrapped around the object to part of the film wrapped around the object.

The present invention provides a central shaft mechanism, which is arranged on the base of a winding machine, including a central shaft component, a central shaft is arranged in the central part of the central shaft component, the central shaft component is also provided with a bearing support structure and a plurality of first limiting structures, and the central shaft component is fixed and limited in the base of the winding machine through the first limiting structures. The central shaft mechanism of the present invention has stable position, stable and reliable operation, and can reduce the working noise and noise during operation. In addition, it can be packed separately from the base during transportation, and can be quickly installed on site, which can not only provide more stable support, but also reduce the height of the turntable of the height winding machine.

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.

A locking device associable to a wrapping machine for locking in a defined locked position a wheeled load to be wrapped with a plastics film, the locking device including a first element elongated along a first direction and arranged to rest on, and be fixed to, a supporting plane of the wrapping machine, and a second element connected to the first element. The second element is provided with a seat open on the supporting plane and includes an inlet opening for allowing a first wheel of the wheeled load be inserted into, or disengaged from, the seat along an insertion direction, and a recess arranged to be engaged by the first wheel in the locked position so as to prevent the first wheel from moving along the first direction and along a second direction, which is substantially orthogonal to the first direction, and from disengaging from the seat.

A method, apparatus and program product utilize curve fitting to control a dispense rate for a packaging material dispenser. Predicted demands at a plurality of rotational positions of a load relative to a packaging material dispenser may be used to generate one or more points to which a curve may be fit, such that dispense rates may be determined for rotational positions between those for which predicted demands have been determined using the curve.

A method of packaging easel includes attaching an easel packaging fixture to a rotatable turntable of a stretch wrapping apparatus that includes a tower and a carriage movable along the tower. An easel bundle is positioned on the easel packaging fixture. Each easel bundle includes one or more easels with a lower portion inserted into a bottom cap and an upper portion inserted into a top cap. The turntable is rotated, causing rotation of the easel packaging fixture and the easel bundle with respect to the stretch wrapping apparatus. As the easel packaging fixture rotates, a wrapping material from the carriage of the stretch wrapping apparatus wraps around the easel bundle. The carriage moves along the length of the tower to wrap a length of the easel bundle.

A machine (100) and a method for stabilising palletised loads (900) are described, comprising: a functional arrangement (105) provided with a reel (110) on which a covering tape (800) is wound, a gripping device (350) adapted to take a first end of the covering tape (800) wound on the reel (110) and to make it integral with the palletised load (900), a first movement apparatus (215) adapted to generate a relative motion of revolution of the functional arrangement (105) around the palletised load (900), according to a predetermined revolution axis (Z), a second movement apparatus (275) adapted to generate a relative motion of translation of the functional arrangement (105) with respect to the palletised load (900) in a direction parallel to the revolution axis (Z), a cutting device (115) placed in the functional arrangement (105) so as to separate the covering tape (800) from the reel (110), a fixing device (400) adapted to fix at least a second end of the covering tape (800) to the palletised load (900).

A method, apparatus and program product implement top layer containment operations to optimize containment of various types of loads such as loads with top/slip sheets, ragged topographies, and/or inboard portions. Bidirectional control of the elevation of a web of packaging material may be performed within one or more revolutions between a load and a packaging material dispenser to selectively engage one or more corners of the load with a web of packaging material while passing the web of packaging material inwardly of one or more other corners of the load.
