(54) | Machine for gluing a liner sheet to a box with means for positioning the box |
(57) The machine for gluing a liner sheet (F) to the base and sides of the outer surface
of a box (S), comprises: a transport device (5) for said sheet (F); feeder means for
feeding individual sheets to a glue spreader (3) and from this to said transport device
(5); conveyor means (9) for conveying individual boxes (S) that are to be lined with
said sheet along guide means (115) at a higher level than said transport device (5);
positioning means (13, 15, 17) for positioning the box over the respective liner sheet
(F) arranged on said transport device (5), with a system of vertical guides (13) down
which the box is pushed toward said liner sheet (F); and a push means (79) for pushing
said box down onto the liner sheet below. The positioning means (13, 15, 17) are carried
by a structure which is provided with a system of actuators (83, 84, 85) and a system
of sensors (A), which move said structure in order to position each box accurately
over the respective sheet arranged on said transport device (5), without modifying
the relative position of said vertical guides (13). |
