Embodiment Construction

[0019] first reference figure 2 , one embodiment of the filling machine relating to the invention comprises the forming and filling of packages from flat web-like packaging material 11 . This web-like packaging material is contained in rolls 31 in boxes 32 and is loaded or conveyed via the boxes 32 to the loading station of the filling machine.

[0020] By way of example, the web of packaging material 11 may be in the form of a flexible paper laminate comprising a paper substrate and a heat-sealable / waterproof layer of polyethylene resin laminated on both sides of the paper substrate. If desired, a barrier layer in the form of aluminum foil or a resin having gas barrier properties is formed between the paper substrate and one or both heat-sealable / waterproof layers. In addition, an external design forming the appearance of the packaging container 33 may be printed on the outer surface of the material.

[0021] The packaging material 11 unwound from the reel to the loading s...

Abstract

A filling machine for the production of containers containing liquid food comprising a set of rollers for forming a web-like packaging material, a filling tube (52) for introducing liquid food into the tubular packaging material as it is conveyed downwards, Heat sealing rods (14, 15) provided with heating means (19) and engageable with cutting rods (18) for creating a sealing zone forming a transverse seal across the tubular packaging material below the position of the food product, and mounted on Cutters on a cutting bar for cutting tubular packaging material in the sealing zone to form preformed containers containing liquid food. At least one nozzle (56) is positioned to direct the sterile cleaning liquid towards the outside surface of the tubular packaging material and / or the cutter. The flushing liquid advantageously cleans and sanitizes the outer surface of the tubular packaging material and can flow downwards to clean and sanitize the sealing rod and cutter. Also, the flushing liquid can cool the packaging material after the transverse seal has been formed, thereby causing the plastic or resinous material of the packaging material to harden relatively quickly. So the plastic or resin material will be less likely to be stained and stained. As a result, the appearance of the packaging material is improved.

Description

technical field [0001] The present invention relates generally to filling machines for filling containers with contents. More specifically, the invention relates to flushing devices for filling machines for filling liquid food products into containers. Background technique [0002] One version of a pack filling machine for filling liquid food products such as milk and juice into containers to produce filled packaging containers involves the use of web-like packaging material on rolls. The web-like packaging material on rolls is loaded into the loading station of the filling machine, from which it is released and conveyed to the filling machine. [0003] The packaging material comprises a flexible laminate which may comprise a paper substrate and layers of polyethylene plastic laminated on both sides of the paper substrate. A barrier layer, which may include aluminum foil and a resin having gas barrier properties, is formed between the paper substrate and the plastic layer,...
