Definitions

  • the present invention relates to a device for mounting cardboard trays, and more especially trays comprising a bottom delimited by two longitudinal walls and two transverse walls, the transverse walls each comprising two longitudinal returns to perform their assembly to the longitudinal walls.
  • This device is also capable of assembling plates which, as a variant, comprise a return parallel to the bottom, called a "sidewalk", itself having two lateral overhangs, folded down and fixed against the longitudinal returns.
  • the forming of a plate is carried out by a tool in the shape of a punch ensuring the folding of the side walls along lines of creasing previously formed on one of the faces of the cardboard blank.
  • the punching tool must keep the glued parts in pressure against each other until the glue has completely set, to ensure a final assembly.
  • This arrangement allows, during each revolution of the carousel, a partial superposition, over time, of the folding and pressure-maintaining operations performed on blanks successively introduced into the machine.
  • the present invention aims to provide a simple device for shaping trays which can advantageously equip a carousel.
  • this shaping device comprises, on the one hand, a matrix comprising several series of shaping ramps delimiting a horizontal opening, vertically offset and arranged longitudinally and transversely to the blank from which the tray is made, and located at the level of the creasing lines that the blank comprises and, on the other hand, a punch comprising two parallel heels arranged symmetrically with respect to a transverse median plane of the blank, this punch being associated with means ensuring its vertical displacement, and the heels being movable towards each other between a spaced apart position in which the outer edges of the heels are located at a distance from each other corresponding to the inner length of the platform and a close up position in which the outer edges of the heels are located at a distance from each other less than the internal length of the plate, the punch control means being arranged such so that, when the blank is brought in, the punch is located above the ramps and then, after positioning it, it is moved vertically downwards, the heels being in the separated position, so that move the blank in contact with the ramps which ensure its shaping, then
  • the lowering phase of the punch corresponds to the shaping of the tray, while the drying is carried out in a position where the glued walls of the tray are kept pinched between the ramps and the punch.
  • the plate shown in FIGS. 1 and 2, obtained from a blank 2 comprises a bottom 3, separated by longitudinal 4 and transverse 5 creasing lines, with respectively longitudinal 6 and transverse 7 walls.
  • the two transverse walls 7 are provided with two longitudinal returns 8 intended to be fixed against the longitudinal walls 6.
  • each transverse wall 7 has a transverse return 9 from which it is separated by a creasing line 10, each return 9 being equipped, at its two ends, with two lugs 12, from which it is separated by creasing lines 13.
  • the returns 9 extend parallel to the bottom of the plate in the direction of the interior thereof, keeping each return 9 in place, also called “sidewalk", being provided by bonding the legs 12 against the longitudinal returns 8.
  • This assembly can be achieved using the machine shown as a whole in Figures 3 to 5.
  • This machine is of the carousel type comprising a central column 14 on which are pivotally mounted four stations 15 of conformation of trays, arranged at 90 ° from each other. These four stations are driven in rotation by steps around the column, by means of a motor, not shown, the output shaft of which carries a pinion 16 meshing with a toothed crown 17, of which a sleeve 18 which surrounds the column is integral. and which is guided in rotation thereon. On the sleeve 18 are fixed four frames 19, belonging to the four shaping devices.
  • Each frame 19 carries a die 20 fixedly mounted, and a punching device 22, which will be described in more detail below, movable vertically between a position in which it is above the horizontal plane for feeding the blanks. and a position in which it is engaged in the matrix, which is itself arranged below the plane of supply of the blanks.
  • the cardboard blanks 2, previously creased and cut, are stored in a magazine 23, with gripping of the lower blank by a device 24, for example with suction cups, depositing this blank on chains 25 with tabs 26, bringing the blanks together , after passing to a gluing station 27 at station A of the carousel, where the blank is taken care of by a shaping device.
  • Each blank is positioned at this level by pressing it comes to take up against a stop 28 integral with the frame 19.
  • the matrix 20 comprises three series of ramps 29, 30 and 32, vertically offset with respect to each other and arranged at the level of crease lines presented by the blank, in order to allow the walls to be folded at the level of said crease lines.
  • the series of ramps 29 ensures the folding of the returns 8 at 90 ° relative to the transverse walls 7
  • the ramps 30 ensure the folding at 90 ° of the transverse walls 7 relative to the bottom 3
  • the ramps 32 ensure the folding of the longitudinal walls 6 relative to the bottom 3.
  • This device comprises a support 33 on which are mounted two arms 34 arranged symmetrically to a diametrical plane of the carousel, in an articulated fashion around two parallel horizontal axes 35.
  • Each of these arms is equipped, at its lower end, with a heel 36, the two heels 36 being parallel and their length being at most equal to the interior width of the plate to be obtained.
  • the arms 34 carrying the two heels are connected, substantially at mid-height, by two links 37, articulated one on the other about a horizontal axis 38 and each of which is articulated on an arm 34 about a horizontal axis 39.
  • a lifting movement of the joint 38 relative to the position shown in FIG. 6 results in a displacement of the two heels in one direction of reconciliation of these.
  • the shaping device also comprises two rollers 40 with axes parallel to the two heels 36 and located at a distance from the bottom of the plate, in the period formed from it, equal to the height of the side walls. These two rollers are arranged symmetrically on either side of a diametrical plane of the carousel and are carried by two rods 42, each articulated around a horizontal axis 43 on the frame 19. These two rods are connected at their upper ends by a spacer 44, articulated around horizontal axes 45.
  • the support 33 is pivotally mounted at the end of an arm 46, the central part of which is articulated around a horizontal axis 47 on the frame 19, and the other end of which is engaged in a groove lower device 48 provided in column 14.
  • the articulation axis 38 of the two connecting rods 37 connecting the arms 34 is mounted at the end of an arm 49 situated in a diametrical plane of the carousel, articulated at 50 around a horizontal axis on the frame 19 and the other end of which is engaged in an intermediate peripheral groove 52 formed in column 14.
  • the spacer 44 connecting the rods 42, is integral with one end of an arm 53 occupying a diametrical position relative to the carousel, articulated in its central part at 54 on the frame 19, and the other end of which is engaged in an upper peripheral groove 55 formed in column 14.
  • the shaping device is also equipped with flaps 56 intended to fold the tabs 12, pivotally mounted on the support 33, and actuated by pneumatic cylinders 57, when the whole of the shaping device occupies a predetermined angular position relative to column 14.
  • a device for shaping the trays being at the station A for supplying the blanks a blank 2 is introduced between the die and the punch until it comes to bear against the stopper 28.
  • the rotational drive of the movable part it is first of all proceeded, by the shape of the grooves 48, 52 and 55, to the descent of the punching device, which performs, as a first step and as shown in Figure 8, the tilting at 90 ° the returns 8 in contact with the ramps 29 then, as shown in FIG. 9, the tilting at 90 ° of the returns 7 in contact with the ramps 30, and finally the tilting of the longitudi walls nales 6, as shown in FIG. 10, in contact with the ramps 32.
  • the two heels 36 are brought closer to each other under the effect of a pivoting of the arm 49, as shown in FIG. 13, and the plate is released downwards using a vacuum device 58 which brings it into contact with a discharge conveyor 59.
  • a vacuum device 58 which brings it into contact with a discharge conveyor 59.
  • the arms 46, 49 and 53 tilt to cause separation heels 36. the spacing of the rollers 40 and the rise of the support 33 before the start of a new cycle.
  • the invention brings a great improvement to the existing technique by providing a device of simple design, with punch of variable geometry, making it possible to ensure the mounting of trays of complex shapes, and which can advantageously equip a carousel machine - taking advantage of the rotational movement around the central column of the carousel to control the various movements necessary and ensure that the glued parts are kept in contact for a sufficient period of time to guarantee perfect geometry of packaging, and its mechanical and storage performance.
