摘要： An unwrapping apparatus for unwrapping a palletized and stretch-wrapped load, including at the front side thereof lower grippers and upper grippers to grip the lower edge and upper edge of a stretchable film of the load, respectively, and a cutter unit for vertically cutting the stretchable film. The unwrapping apparatus includes at the rear side thereof a carriage having a platen to press the top of a load, a pair of swing arms carrying the upper grippers, and a pair of auxiliary film separating swing arms to separate the stretchable film from the rear corner portions of the load when the film is removed from the load by the main swing arms. The main swing arms and the auxiliary swing arms prevent the articles from being pulled and moved by the stretchable film in contact with the articles and thus falling down from the separate sheet in particular.

摘要： An unwrapping apparatus for unwrapping a palletized and stretch-wrapped load, the apparatus enables the prevention of the articles from falling off and easy disposal of the used stretchable film. The apparatus comprises first and second upright frames between which a load to be unwrapped is conveyed, the first upright frame including two lower grippers for gripping a lower edge of the stretchable film, and an elevated cutter unit having two pairs of pinch rollers and a heat cutter. The second upright frame includes a carriage having a platen to press the top of the load to be unwrapped and a pair of swing arms symmetrically arranged on either side of the platen and extending toward the first upright frame. Upper grippers are secured to the swing arms, respectively. The stretchable film can be gripped during the cutting and unwrapping of the load to maintain tension and prevent the articles in the load from falling off. In addition, the used stretchable film can be discharged in a compressed, compact form.
