Abstract
A method and the relative device for packaging ordered groups of products in a carton comprises the following stages: feeding one carton at a time, in the form of a flat pre-folded blank, to a loading table and simultaneous opening of the blank, by means, to form a tubular carton body with two opposite openings one on either side, two first pairs of smaller flaps and two second pairs of larger flaps or lids; folding of the two pairs of smaller flaps, by first means, during carton feed in a preset direction, so as to form a first partial closure of the openings; and closing of the carton body, by second means, by simultaneous folding of the pair of lids towards the two openings so as to obtain a closed package. FIGS. [1-7]
Claims19
A method for packaging ordered groups of filter bags containing doses of products for infusion comprising at least a station for forming a group of a preset number of filter bags arranged in a row, the method comprising:
- simultaneously feeding one carton at a time, in the form of a flat pre-folded blank, on a loading table and opening the blank to form a tubular carton body, having two opposite openings, one on either side, two first pairs of smaller
- moving by a rotation and translation movement the end of a passage between a lowered operating position in which the passage is substantially coplanar with the loading table to feed the row of products into the carton body through one opening of the carton body positioned opposite the end of the passage for the row of products, allowing the row of products to be fed into the carton body in a direction of feed perpendicular to a preset direction of movement of the carton, and a raised non operating position in which the passage is distanced from the carton;
- folding the two pairs of smaller flaps, as the carton is fed in the preset direction, to form a first partial closure of the openings;
- and
- closing the carton body on said loading table, by simultaneously folding the pair of lids towards the two openings so as to obtain a closed package.
A device for packaging ordered groups of filter bags containing doses of products for infusion comprising at least a station for forming a group of a preset number of filter bags arranged in a row, the device comprising:
- means for forming an individual tubular carton body which is fed in the form of a flat pre-folded blank from a magazine and onto a loading table in such a way as to obtain the carton body with two opposite openings, one on either side, to which two pairs of flaps and a pair of lids are attached, the carton body being in an open configuration to allow insertion of at least one row of products, one of the openings of the carton body being positioned opposite the end of a passage for the row of products, to allow the row of products to be fed into the carton body in a direction of feed perpendicular to the direction of carton feed;
- the passage presenting a pair of lateral walls adapted to be in contact with the flaps and being mobile by a rotation and translation movement between a lowered operating position, in which the passage is positioned on a lid of the carton and coplanar with the loading table and in which the lateral walls keep the flaps open, and a raised non-operating position, in which the passage is distanced from the lid;
- first means for folding the two pairs of smaller flaps, operating at the loading table and designed to allow the two pairs of smaller flaps to rotate in such a way as to obtain a first partial closure of the openings as the carton is fed in a preset direction;
- and
- second means for folding the lids, being located close to the carton body and downstream of the first folding means relative to the direction of feed, and being designed to allow at least a simultaneous closing rotation of the lids towards the carton body, the lids being attached to the carton body in such a way as to form a closed package.
