Definitions
- the invention relates to a method of shaping and folding a rectangular packaging box from a pre-cut and pre-folded sheet of cardboard while being stored flat in a storage state.
- the physical constraints rest mainly on the operators, the handling and the shaping of the empty cartons being able to generate vertebral pathologies and musculoskeletal disorders, if the operator's efforts are made in unfavorable angular positions.
- the edges of the cardboard are sometimes sharp, with the risk of superficial injuries. Gripping large boxes causes a feeling of discomfort.
- Document EP-A-543 786 describes a device for automatically folding the flaps of cardboard packaging in two different stations. The first station folds the cross flaps, while the second station folds the side flaps.
- the document EP-A-113 899 relates to a device for closing cartons, in which the cartons are transported along a conveyor belt forming an angle.
- Fixed folding members fold the interior and exterior flaps following a relative movement of the cardboard.
- Document EP-A-567 769 mentions a device for folding the bottom of a packaging carton in a single operation. The mechanism is nevertheless complicated, and has a large bulk.
- Document EP-A-698 555 relates to a device for closing a tubular cardboard box of rectangular shape, one of the sets of opposite flaps of which is in the form of bellows.
- a control mechanism comprises two pairs of folding fingers rotated continuously at the same speed by means of a gear system driven by a common motor.
- Document DE 2237092 relates to a device for forming a cardboard box in which the cardboard is shaped by means of a jack.
- the mechanism is designed for a predetermined type of cardboard which must fit the frame and the piston of the cylinder.
- the object of the invention is to develop a simple method and device for shaping and folding a cardboard packaging box, making it possible to optimize the ergonomics and comfort of the operator by reducing the handling, and improve the quality of the packaging.
- the method according to the invention is characterized by the following successive steps:
- the process is semi-automated thanks to a work station which automatically forms the bottom of the carton in complete safety, as well as the ergonomic height adjustment of the carton, leaving the operator to fill and close it at the level of the cover.
- the device for implementing the method comprises: a base for supporting a frame having an orifice in the central part, - a first pair of actuating elements pivotally mounted on said base while being arranged symmetrically from one side and on the other side of the orifice for actuating the two lateral flaps, a second pair of actuating elements pivotally mounted on said base for actuating the two transverse flaps, - a stop element for setting manual shape of the box, and successive drive means of the two pairs of actuating elements for the automatic folding of said flaps during the forming of the bottom of the box.
- the stop element is adjustable in height, and is composed of a wedge-shaped stud at right angles.
- the stop element advantageously forms part of a shaping tool adaptable to the frame, said tool being equipped with pneumatic suction cups to keep the carton in the open state during the second phase of folding the flaps and forming the bottom.
- the suction cups are connected by connectors to a compressed air supply unit, the coming into contact of the walls of the box against the suction cups during the first phase of manual shaping, causing the automatic start of the second bottom forming phase.
- the actuating elements of the two pairs are formed by cams articulated on parallel axes extending perpendicular to the horizontal plane of the base.
- An operating lever is associated with each actuation cam of the second pair to open and then block the side flaps in the open position when the transverse flaps are folded.
- a movable compensation plate crosses the orifice of the base to recover the difference in height at the end of the folding operation of the flaps, so as to bear against the bottom of the box.
- the actuating elements comprise spacer levers made active for one of the pairs of flaps when the other pair of flaps is folded by folding levers.
- a bellows is provided at the bottom of the frame to serve as a means of protection for the height adjustment system of the compensation plate.
- the means for driving the cams or the levers can be coupled to mechanical, hydraulic, pneumatic or electric actuators.
- FIG. 1 is a plan view at the start of manual shaping of the cardboard bearing on the stop element
- Figure 2 is an identical view to Figure 1 at the end of shaping the carton, with hatched lines the free part for the operator;
- FIG. 3 shows a perspective view of the box in the open state of the bottom flaps
- FIG. 4 shows a perspective view of the box with the bottom completely open, the folding of the flaps being effected with cams according to a first embodiment
- FIG. 5 is an identical view to Figure 4 when the transverse flaps are closed by the second pair of actuating cams;
- FIG. 8 is a rear perspective view of the device of Figures 4 to 7 showing the stop member and positioning of the carton;
- - Figure 9 shows a plan view of Figure 4;
- FIG. 10 is a schematic perspective view of a second embodiment showing the tool adaptable to the frame . of the machine, said tool being equipped with the shaping corner and a pair of suction cups for holding the cardboard when folding the flaps;
- FIGS. 11 to 14 illustrate the different phases of folding the flaps of the device in FIG. 10.
- the device 10 for shaping and folding a cardboard packaging box 12 comprises a support base 14 equipped with a stop element 16, and two pairs of cams d actuation 18a, 18b; 20a, 20b.
- the base 14 is flat and rigid, and includes a square orifice 22 in the central part.
- the orifice 22 can of course have another shape, for example round.
- the opposite actuating cams 18a, 18b of the first pair are mounted for rotation on vertical axes 24a, 24b extending perpendicular to the horizontal plane of the base 14.
- the two actuating cams 18a, 18b are identical and arranged symmetrically with respect to the center of the orifice 22.
- the actuating cams 20a, 20b of the second pair are articulated on vertical axes 26a, 26b parallel to the other two axes 24a, 24b.
- a pivoting operating lever 28a, 28b is mounted on each axis 26a, 26b, the assembly being symmetrical relative to the center of the orifice 22.
- the drive means of the different cams 18a, 18b; 20a, 20b are controlled by mechanical, hydraulic, pneumatic or electric actuators.
- each cam 18a, 18b; 20a, 20b is inclined upwards, and comes into engagement with the cardboard flaps during the folding operation.
- the stop element 16 is adjustable in height, and comprises a pillar 30 carrying a stud 32 in the form of a corner at a right angle.
- a movable compensation plate 34 passes through the orifice 22 of the base to recover the difference in height at the end of the folding operation of the flaps.
- the four cams 18a, 18b; 20a, 20b are staggered substantially at 90 ° on the base 14, around the four lower flaps 36a, 36b; 38a, 38b from the box
- the transition from the storage state where the pre-cut cardboard is stored flat, to the preformed packaging state, is carried out in two distinct phases occurring on the same workstation.
- the first phase is the manual shaping of the box 12 illustrated in FIGS. 1 and 2.
- the flat cardboard is placed in an upright position placed on the lower edge, so as to be perpendicular to the base 14. It suffices for the operator to position one of the corners of the carton in the corner of the stop element 16, and push in the direction of arrow F1 to cause the separation of the walls of the carton (arrow F2) until obtaining the right quadrilateral with open bottoms.
- the stop element 16 is part of a shaping tool adaptable to the frame, said tool being equipped with pneumatic suction cups V1, V2 to maintain the cardboard in the open state during the second phase of folding the flaps and forming the bottom.
- FIG 3 is shown the box 12 after shaping. It has lateral faces F1, F2, F3, and F4 parallel two by two to form the right quadrilateral. Each side F1, F2, F3, and F4 is associated with a flap 38a, 38b, 36b, 36a intended to be folded at right angles inward to form the bottom of the box 12.
- the range of cardboard used for the machine are boxes of the "American box" type, square or rectangular, 200 to 800 mm long.
- the second phase is the automatic folding of the flaps 36a, 36b; 38a, 38b at the level of the open bottom bottom bottom.
- the two transverse flaps 38a, 38b are first closed by reverse tilting at right angles around their fold lines following the rotation of the two cams 20a, 20b of the second pair.
- the pivoting operating levers 28a, 28b follow the rotational movement of the cams 20a, 20b by opening and keeping the side flaps 36a, 36b open, so as not to hinder the folding operation.
- the two lateral flaps 36a, 36b are closed after exhausting the operating levers 28a, 28b, by rotating the cams 18a, 18b of the first pair.
- the parallel fold lines of the two side flaps 36a, 36b are perpendicular to the fold lines of the transverse flaps 38a, 38b.
- the bottom of the box 12 is then closed, and the lifting of the compensation plate 34 recovers the difference in height by pressing against the bottom after folding the flaps 36a, 36b; 38a, 38b.
- this compensation plate 34 can also be used for the evacuation of the box 12, or the packaging of the object to be packaged. The operator's efforts are reduced to a minimum, since he only handles the cardboard flat.
- the folding of the side flaps 36a, 36b and transverse 38a, 38b for closing the lower bottom is carried out automatically by driving the cams 18a, 18b; 20a, 20b, the box 12 remaining stationary in the same position.
- the shaping and folding of the flaps 36a, 36b; 38a, 38b of the box 12 can intervene directly on the packaging station.
- the product to be packaged is introduced from above, while the bottom is resting on the compensation plate 34.
- the suction cups V1, V2 are connected by connectors 50 to a compressed air supply unit (not shown), the coming into contact of the walls of the box 12 against the suction cups V1, V2 during the first phase of manual shaping, causing the second phase of bottom forming to start automatically.
- the suction cups V1, V2 are part of the tool 52 provided with the stop element 16.
- the tool 52 is fixed to the frame 54 of the machine by assembly tabs 56.
- a bellows 58 in polyester fabric is provided in the lower part of the frame 54 to serve as a means of protection of the height adjustment system of the compensation plate 34.
- the actuating elements comprise spacer levers LE1 for one of the pairs of flaps 36a, 36b when the other pair of flaps 38a, 38b are folded by folding levers LR1 (see FIGS. 11 and 12).
- Figure 13 shows the closure of the flaps 36a, 36b using two folding levers LR2.
- FIG. 14 shows the compensation plate 34 in the raised position for the ergonomic height adjustment and keeping the bottom of the carton closed to allow it to be filled. This results on the one hand in saving time thanks to the reduction in handling, and on the other hand an improvement in the quality of the packaging since the operator can focus his attention on the product to be packaged. The risks of musculoskeletal disorders are also reduced, because the operator no longer returns the box.
