Embodiment Construction

[0026] With reference to the accompanying drawings, figure 1 A winding device or winding machine according to the invention is shown, indicated generally at 10 .

[0027] As will be explained below, the device 10 is designed to wrap a strip of suitable plastic film around the articles 11 arranged in the packaging area 38 of the machine. The introduction of the articles into the packaging area 38 (and the optional removal of the articles) may be carried out, for example, by means of a conveyor line 21 , advantageously a belt conveyor or a roller table.

[0028] The winding station forms a station for packaging products, for example palletized, as can be easily imagined by a person skilled in the art. Typically, the article 11 may be formed by a group of products (eg boxes, bricks, etc.) Fastened in a single package.

[0029] The winding machine 10 comprises a frame 13 carrying a dispensing unit 19 electrically controlled so as to dispense packaging film from the reels of fil...

Abstract

A rotary wrapping machine (30, 110) for packaging products by means of a film unwound from a reel comprises a frame (13, 113) carrying a dispensing unit ( 19, 119) which is electrically controlled to dispense the packaging film from a reel of film present in the dispensing unit (19, 119). The dispensing unit is supported on the frame so as to be driven rotationally along a closed path around a packaging zone (38, 138) which contains a product to be wrapped with the film. Along the closed path there is a power supply antenna (25, 125) which is connected to an antenna power supply unit (26, 126) for transferring, by means of electrical induction, electric power to a corresponding receiver (28, 128) which is movable along the antenna together with the said dispensing unit and which supplies in turn electric power to the dispensing unit.

Description

technical field [0001] The present invention relates to an innovative rotary wrapping machine of the type that uses film strips to package articles, such as packages on trays. Background technique [0002] Winding machines or wrapping stations are known which have a wrapping head or wrapping unit which rotates along a circular path around the periphery of an article to be wrapped arranged at the center of the path. The wrapping head unwinds the plastic film from the reel and winds the plastic film around the article. If the width of the film is less than the height of the product, the machine must also perform a simultaneous displacement of the packaging head along the product itself, so that the film is wound helically on the product. [0003] For the rotary movement of the packaging head, the machine can be provided with a motor-driven circular ring for axial rotation, on the inner circumference of which the film dispensing unit is mounted. The ring may also include coun...
