Abstract
An apparatus for packaging packets for smoking articles includes a transfer wheel to transfer the packets from a feed device to an outlet device. A gluing device is disposed in a certain angular position between the feed device and the outlet device to selectively glue two lateral flaps of each packet on the corresponding lateral walls thereof. A pressing device is disposed outside the transfer wheel between the gluing device and the outlet device to press the lateral flaps of the packet against corresponding lateral walls thereof.
Claims11
Apparatus for packaging packets of smoking articles, wherein each of said packets comprises a box-like body having at least two opposite lateral walls, each lateral wall being formed by at least one respective internal flap and at least one external flap, which are overlapping each other and able to be glued together, said apparatus comprising:
- a transfer wheel selectively rotatable around a first axis of rotation and configured to move said packets along an arcuate transfer path, wherein said transfer wheel circumferentially comprises a peripheral surface provided with a plurality of seatings, each of which is configured to temporarily hold one of said packets along said transfer path;
- a feed device disposed in a first fixed angular position with respect to said transfer wheel at the beginning of said transfer path and configured to individually feed packets to be glued toward said seatings;
- an outlet device disposed in a second fixed angular position with respect to said transfer wheel at an end of said transfer path and configured to receive said packets, after the packets have been glued, coming from said transfer wheel;
- a gluing device disposed outside said transfer wheel in an intermediate angular position between said feed device and said outlet device, and configured to selectively deliver a glue on said packets to be glued, wherein each of said seatings is oriented so that, in said seating, a respective packet to be glued is disposed along said transfer path with the respective internal flaps of each lateral wall disposed perpendicular to said first axis of rotation, wherein said apparatus also comprises a movement device configured to move said gluing device along a path substantially radial with respect to said transfer wheel, taking said gluing device closer to, or away from, said peripheral surface, in coordination with the rotation of said transfer wheel, in order to deliver said glue on at least one of either said internal flap or the corresponding external flap of each lateral wall of the packet to be glued when the packet passes in front of said gluing device, the movement of said gluing device being adjusted in such a way as to deposit said glue along a programmed disposition while said packet to be glued advances along said transfer path.
Method for packaging packets of smoking articles, wherein each of said packets comprises a box-like body having at least two opposite lateral walls, each lateral wall being formed by at least one respective internal flap and at least one external flap able to be glued together, said method comprising the following steps:
- a movement step, in which a transfer wheel, selectively rotatable around a first axis of rotation, is selectively rotated in order to move said packets along an arcuate transfer path, from a feed device, located in a first fixed angular position, to an outlet device, located in a second fixed angular position, and a gluing step in which a gluing device, disposed outside said transfer wheel in an intermediate angular position between said feed device and said outlet device, selectively delivers at least one glue on said packets to be glued, each packet to be glued being disposed along said transfer path with the respective internal flaps of each lateral wall disposed perpendicular to said first axis of rotation;
- wherein during said gluing step said gluing device is moved along a path substantially radial with respect to said transfer wheel, taking said gluing device closer to, or away from, said transfer wheel, in coordination with the rotation of said transfer wheel, in order to deliver said glue between at least each one of said internal lateral flaps and the corresponding external lateral flaps of the packet when the packet passes in front of said gluing device, the movement of said gluing device being adjusted in such a way as to deposit said glue along a programmed disposition while said packet to be glued advances along said transfer path.
