- FIG. 1 represents a perspective view of a packaging box according to the invention
- Figure 2 shows a flat view of a packaging box
- FIG. 4 represents a view from above of a machine according to the invention
- Figure 1 shows an example of packaging comprising two funds (100, 200) cardboard and a window (300) disposed between the two cardboard funds (100, 200).
- the window (300) is typically cut from a PVC sheet, to which a grooving (302) is applied to to facilitate the folding and to avoid that during the shaping, the sheet of PVC, more rigid than the cardboard, does not come to tear the cardboard at a ridge, in the zone of connection of the cardboard and the PVC.
- the transparent window (300) may also have notches (301) at the edges at the fold lines (302) to prevent the stiffness of the PVC from creating a deformation exerting on the carton a pressure which may lead to a tear local.
- Figure 2 shows the assembly between the cardboard blanks (100; 200) and the window (300) prior to shaping.
- the manufacture of a packaging box according to the invention comprises the following main steps:
- a series of blanks formed of two blanks (100, 200) separated by a transverse space (150) and punctually connected by breakable zones (160) are cut in a cardboard sheet, and these blanks are stacked on a blank unstacker.
- the cardboard blanks are then driven one by one on a conveyor belt to a cut processing station.
- the cardboard cut is stuck, on at least part of its displacement, between the conveyor belt and a pair of rollers supported on the upper surface of the cut.
- the rollers initially rotate at a speed synchronous with the belt so as to ensure the displacement of the cut without speed differential between the lower part and the upper part.
- traction is then exerted on each of the blanks (100, 200) in opposite directions perpendicular to the median of the transverse space (150).
- This traction is achieved by changing the speed of both rollers, when positioned on either side of the breakable zone (160) of the blank. For example, the roller is slowed down behind this breakable zone, so as to create a force in a direction perpendicular to the breakable line.
- This effort causes breakage of the breakable areas (160) and allows to separate the two blanks (100, 200), to position them facing each other with a shift corresponding to the transparent sheet (300).
- a window is then superimposed with the two edges of the blanks (100, 200), an adhesive is deposited on the edge of the strips (110, 210) and the window is deposited on the glued area.
- FIG. 4 illustrates a particular example of equipment for implementing the method according to the invention.
- the equipment comprises a suction mat (1) running longitudinally.
- the blank (2) is deposited on this suction belt (1) by a destacker, and slides under pressure rollers (3 to 5).
- the blank (2) is then driven between the belt (1) and a motorized transverse roller (6).
- a belt rework module (7) separates the two blanks (100, 200) from the blank (2).
- the purpose of the equipment is to detach and separate, parallel to a predefined distance, the cardboard cut (2) consisting of two or three pieces held in them by breakable zones (160).
- a belting device (7) realigns in parallel the cardboard blanks (100, 200) on the suction belt (1) and ensures also the correct preprogrammed distance of the cuts (100, 200) between them.
- the pressure rollers (6) slow down while the front blank (200) of the cardboard blank (2) continues to advance at the same speed as the suction belt (1) and is maintained under pressure by the pressure rollers (3 to 5 ) on the carpet (1). After separation of the blanks (100, 200), the rollers (6) accelerate to return to the same speed as the belt (1) at a specific time, determined beforehand by the separation length of the two blanks (100, 200).
- the blanks (100, 200) separated advance to the belt rework module (7).
- the blanks (100, 200) are then realigned by the thrust and the retention of the straight edges of the two cardboard blanks (100, 200).
- the belting module (7) consists of two belt carriages connected in parallel.
- the two toothed belts are motorized by a splined shaft with ball bushing, allowing a lateral adjustment of each carriage.
- Each of the toothed belts is provided with a welded cleat.
- Each belt has a micro-adjustment device, which allows alignment of the two cleats in parallel or angular correction of the cardboard blanks.
- the synchronization settings of the cleats / at the position of the cuts, can be set on the machine's console.
- Principle for aligning 2 blanks (100, 200):
- Phase 1 The cleat pushes from the back the first blank (200) of the board separated previously upstream.
- Phase 2 Accompanying the thrust of the first blank (200) from 2 to 5 millimeters.
- Phase 3 Accompanying end of the thrust of the first blank (200) of the carton from 2 to 5 millimeters and return of the cleat rearwardly to come to be positioned on the front edge of the second blank (100).
- Phase 4 Slowing of the second blank (100) by 2 to 5 millimeters with respect to the belt (1), when the breakable zone is between the first and the second roll, then rotation of the cleat for preparing the next carton.
