Abstract
Embodiments include a carton feeding device for feeding cartons to a conveyor track, comprising a pick-up head with a plurality of vacuum cups, an erecting finger pivotally suspended at the pick-up head, where the pick-up head has a pick-up position (P1) and an insertion position (P2), where the carton is held with an angle α between the holding plane of the pick-up head and the bearing surface of the erecting finger, wherein the angle α differs from 90 degrees with at least 10 degrees in the insertion position (P2), where the carton is inserted between two parallel teeth of the conveyor track, and where the distance between the teeth is substantially equal to the width of the upper wall of the carton.
Claims15
A carton feeding device for feeding cartons to a continuously moving conveyor track, comprising
- a pick-up head with a plurality of vacuum cups, and an erecting finger pivotally suspended at the pick-up head, where the pick-up head has a pick-up position (P1) in which the holding plane of the pick-up head is positioned parallel to the folded carton blank that is to be picked up, and an insertion position (P2) in which the erecting finger is pivoted with respect to the holding plane of the pick-up head in such a way that the carton is opened, and where the carton is held with an angle α between the holding plane of the pick-up head and the bearing surface of the erecting finger,
- and where the pick-up head holds the carton by an upper wall, wherein the angle α differs from 90 degrees with at least 10 degrees in the insertion position (P2), that the carton is inserted between two parallel teeth of the conveyor track, and that the distance between the teeth is substantially equal to the width w of the upper wall of the carton, and where the pick-up head moves along the conveyor track during the insertion of the carton.
A method for feeding a carton to a continuously moving conveyor track, where the conveyor track comprises parallel retaining teeth spaced apart with a distance that is substantially equal to an erected carton, comprising the steps of:
- picking up a carton blank from a magazine with a pick-up head,
- rotating the pick-up head by less than 180 degrees,
- at the same time, open the carton with an erecting finger such that the shape of the erected carton is rhombic,
- inserting the rhombic carton between the retaining teeth, where the pick-up head moves along the conveyor track,
- releasing the carton from the pick-up head.
