Abstract
A device for unfolding packaging carton sleeves having a mechanism for providing the flat carton sleeves, a transfer unit, which can be rotated about a rotational axis, having at least one suction member for adhering to the carton sleeves and for transferring the carton sleeves to a conveyor belt, wherein the suction member is at a distance from the rotational axis. The conveyor belt includes at least one pocket for receiving the carton sleeves. The distance between the suction member and the rotational axis is constant and consequently the carton sleeves are channelled along a circular track.
Claims22
A device for unfolding packaging carton sleeves comprising:
- a mechanism for providing flat carton sleeves,
- a transfer unit, which can be rotated about a rotational axis and which has a plurality of suction members for adhering to the carton sleeves by suction, and for transferring the carton sleeves to a conveyor belt, wherein the suction members are at a distance from the rotational axis, wherein
- the conveyor belt comprises at least one pocket for receiving the carton sleeves,
- wherein
- the distance between the suction members and the rotational axis is constant and consequently the carton sleeves are channelled along a circular track, and wherein all of the suction members are arranged at the same distance from the rotational axis of the transfer unit.
(canceled)
A method for unfolding packaging carton sleeves comprising the following steps:
- a) provision of carton sleeves by a mechanism,
- b) adhesion to the carton sleeves by suction and advancement of said carton sleeves by a transfer unit rotating about a rotational axis having a plurality of suction members, and
- c) unfolding the carton sleeves by inserting said carton sleeves into a pocket attached to a conveyor belt, wherein
- the transfer unit channels the carton sleeves along a circular track at a constant distance between the suction members and the rotational axis wherein the carton sleeves are unfolded solely as a result of the effect of the suction members and the pocket on the carton sleeve.
