Automatic packaging machine for filling bag made of heat-sealable material with dose of loose product

Abstract

Automatic packaging machine (3) for filling a bag (1) made of heat-sealable material, having an open upper end (2) with a dose of loose product; the packaging machine (3) has: a packaging conveyor (4); a pick-up head (7), which is supported by the packaging conveyor (4) to advance along a packaging path (P1); an input station (S1) where the empty bag (1) is grabbed by the pick-up head (7); an output station (S2) where the full, sealed bag (1) leaves the pick-up head (7); a filling device (18) that is mounted on the packaging conveyor (4) to move together with the pick-up head (7) along the entire packaging path (P1) and is adapted to supply the dose of product inside the bag (1) through the upper open end (2); and a sealing device (19) that is mounted on the packaging conveyor (4) to move together with the pick-up head (7) along the entire packaging path (P1) and is adapted to seal the full bag (1) through a heat-seal in correspondence with the open upper end (2).

Description

technical field [0001] The present invention relates to a product that uses a certain amount of loose product (a product that does not have any adhesion between its components, any adhesion and thus does not have its own shape, such as a powder product, a grated product, or a liquid product) ) Automatic packaging machines for filling bags of heat-sealable material. [0002] The invention is advantageously applied to an automatic packaging machine for filling bags of heat-sealable material with a quantity of loose food products, for which reason reference will be made to it in the following description without loss of generality. Background technique [0003] Patent applications EP2722282A1 and WO2012136869A1 describe automatic packaging machines for filling bags made of heat-sealable material with a predetermined quantity of loose food products with a certain quantity of loose food products; The packaging conveyor of the head, so that the pick-up head advances along the pac...
