Definitions

  • the present invention relates to the placement on flat supports, such as cardboard blanks for example, of sheet elements, such as windows or sachets, and aims to solve the problem of automatic and precise removal, at high rate, of said sheet elements, one by one, on individual flat supports.
  • the object of the present invention is precisely to solve this problem and that, more generally, of the precise placement at high speed, of any sheet element (plastic film, window, sachet, paper, cardboard, PVC, etc.) on a flat support, in particular a blank of cardboard or other material, cut and grooved to form a folding box, composite or not.
  • any sheet element plastic film, window, sachet, paper, cardboard, PVC, etc.
  • a flat support in particular a blank of cardboard or other material, cut and grooved to form a folding box, composite or not.
  • said gripping and depositing member is constituted by at least one suction cup and the means suitable for conferring on this member said trajectory are constituted by a suction cup holder rotatably mounted around an axis parallel to the axis of the pressure roller and itself driven in rotation about an axis which is parallel to it, in synchronism with the speed of rotation of the pressure roller, means being provided, indexed on the rotation of the axis of the suction cup holder, to give at the suction cup, said hypocycloidal curve with the two cusps at the two gripping points and deposits elements in sheet respectively.
  • said sachets are detachably secured by tearing off heels, the whole heel-sachets being bundled and stored in said store and , in order to facilitate tearing of the sachets, means are provided for communicating to said gripping member and depositing, when gripping a sachet, a slight and clear backward movement, without interrupting the continuous movement of said gripping member and depositing a trajectory hypocycloid.
  • FIG. 1 there is shown in 1 a suction conveyor responsible for conveying one by one of the blanks of cardboard 2 cut and grooved intended to constitute cases of composite boxes with internal sachet, said blanks being placed on the conveyor 1 to the using an appropriate positioning device 3.
  • the blanks 2 are transferred to a conveyor 4 arranged in the extension of the conveyor 1, where they are first glued, in the known manner, by a gluing device 5 responsible for depositing on the upper face of each blank 2 the lines gluing the sachet which must be placed on the blank and whose positioning must be particularly precise. Two such bonding lines have been symbolized by way of illustration at 6 in FIG. 1.
  • FIG. 1 The installation of FIG. 1 comprises a suction cylinder 7 of the type used on "cellophanates” or machines for placing windows in window boxes, which cylinder 7 is responsible for transferring onto the blank 2 passing under it a bag 8 constituted by example of a pocket of transparent thin plastic film, closed at one end and open at the other, and brought by a rotary feeder according to the invention and generally designated by the reference numeral 9.
  • the feeder 9 is responsible for removing, one by one, the bags 8 stored at 10 in the feeder, stacked with their plane arranged vertically, parallel to the axis of the suction cylinder 7.
  • a mechanism for gripping and depositing the bags 8 one by one is provided for taking the bags 8 from the magazine 10 and depositing them on the cylinder 7 and more precisely making them pinch between the latter and a pressure roller 11, applied elastically against the cylinder 7 and trained at the same speed as him.
  • This gripping and depositing mechanism comprises three suction cup holders 12, carried by bars 13 parallel to the axis of the suction cylinder 7 and rotatably mounted in two circular flanges 14a and 14b wedged on a shaft central 15 also parallel to the axis of the cylinder 7.
  • the bars 13 are equidistant from the shaft 15 and offset between them by 120 °.
  • the shaft 15 and the flanges 14a, 14b are rotated in synchronism with the cylinder 7 by an appropriate transmission 16, the direction of rotation 17 of the assembly 15-14a, 14b being opposite to that of the cylinder 7.
  • the assembly 15-14a, 14b is mounted journalling in two lateral, vertical frame plates 19.
  • Each suction cup holder 12 is mounted in a fixed but adjustable manner along the bars 13 and comprises a set of two suction cups connected by a flexible pipe 20 and an O-ring connection 21 to a vacuum source not shown.
  • One (22) of two suction cups has a substantially larger surface area than that of the other suction cup 23.
  • the bars 13 pass through one (14a) of the flanges and are integral at their end with a kind of pinion 24 provided with teeth 25 capable of meshing with a fraction of crown 26 integral with the frame 19 and internally carrying a toothing formed by 'pins or projections 27 located on the path of the teeth 25.
  • the crown 26 extends over an arc of 180 ° and is coaxial with the axis of the shaft 15.
  • the half-crown 26 extends from the lowest point of the bars , during the rotation of the assembly 15-14a, 14b, which corresponds to the point of depositing a bag 8 (FIG. 3) on the cylinder 7, up to the highest point.
  • the hypocycloidal trajectory 30 of the central contact point of the suction cup 22 has been illustrated with a bag 8, with in particular the turning point 31 of the suction cup 22 at the level of the magazine 10 and the turning point (theoretical) 32 of the suction cup 22 at the level of the cylinder 7.
  • the pinions 24 are dimensioned so that between the two successive cusps (32 then 31 following the direction of rotation 17 of the shaft 15) the shaft 15 has described an arc of 90 °, the magazine 10 of the feeder being placed accordingly.
  • Such a hypocycloidal trajectory 30 allows the suction cup 22 to contact a bag 8 of the magazine battery 10 with an approach perpendicular to the bag and a zero speed at the time of contact, which will also be that of the vacuum applied to the suction cup 22, which results in an entry with a particularly clean, precise and repetitive positioning of the suction cup at any speed of rotation of the shaft 15, that is to say at any rate of conveying of the blanks 2 by the conveyor 4.
  • the suction cup 22 continues its hypocycloidal movement (30 ′) ascending to a point diametrically opposite to point 32 relative to the shaft 15 and corresponding to the moment when the pinion 24 leaves the half crown 26 at its upper end.
  • the suction cup 22 carries with it a bag 8. From the high point of the trajectory of the suction cup 22, the latter then describes a simple circle up to the point of cusp 32 as shown on the right side of Figure 3, the suction cup 22 with its bag 8 being turned outwards.
  • the bag 8 is released by the suction cup and is supported on the cylinder 7 by the suction orifices 7a of the cylinder (FIG. 2).
  • the suction cup touches the cylinder 7 with zero relative speed, the cylinder 7 and the rotary assembly 13-15-22 being driven at the same speed of rotation.
  • the positioning of the bag on the cylinder 7 is therefore particularly precise and repetitive at any rate.
  • FIG. 6 illustrates a method of packaging the bags 8 which is particularly suitable for the device of the invention.
  • FIG. 6 there is shown a bag 8 in the flat state connected at the top to a heel 8a separated from the bag by a line of incisions 8b.
  • the heel 8a is constituted for example by the extension of one of the walls of the bag 8.
  • the heel 8a is pierced with two secant holes 8c relative to the line of incisions 8b.
  • each bag 8 is gripped by the large suction cup 22 in the vicinity of the separation line 8b and by the small suction cup 23 in the vicinity of the other end.
  • FIGS. 4a to 4f The precise process of entering and tearing off a bag 8 from the magazine 10 is illustrated in FIGS. 4a to 4f.
  • FIGS. 4a to 4c illustrate the end of the hypocycloidal stroke 30 of the suction cup 22 up to the cusp point 31 (FIG. 4c).
  • the suction cup 23 begins to peel off the lower part of the bag 8 ( Figure 4b) when the suction cup 22 begins to contact the upper part of said bag.
  • This mechanism illustrated in FIG. 2 comprises a cam 34, adjustable in angular position, moved rotation in synchronism with the shaft 15 and provided with a recess 35.
  • the cam 34 acts on a pusher 36 sliding in a guide 37 secured to the frame 19 and articulated at its end on a pin 38 secured to the half-crown 26 in sort of communicating to the latter a slight rotational movement around the axis of the shaft 15, the half-crown being mounted on ball bearings for this purpose on the frame 19.
  • FIGS. 5a to 5c respectively illustrate the reaching by the suction cup 22 of point 32 (removal of the bag on the cylinder 7), the bag 8 being still held by the two suction cups 22 and 23, then (FIG. 5b) the start of the hypocycloidal trajectory 30 of the suction cup 22 also causing that of the suction cup 23 which withdraws, the suction cup 23 being vented to release the bag 8 as well as the suction cup 22 and, finally (FIG. 5c), the retraction towards the inside the suction cups 22, 23 so as to escape from the pressure roller 11.
  • FIGS. 7 and 8 illustrate an embodiment of a loader or magazine 10 storing the bag 8-heel 8a assemblies side by side vertically. These assemblies are suspended from two horizontal fingers 33 engaged in the holes 8c.
  • the gripping plane of the bags 8 is delimited by a vertical frame 39 provided with fingers 40 for peripheral retention of the bags.
  • the fingers 33 beyond the frame 39 (suction cup side 22, FIG. 8), are bent upwards at 33a so as to collect, with a view to their evacuation, the heels 8a which remain threaded on the fingers 33 after tearing of the bags 8.
  • An endless belt 41 provided with projections 42 driven by appropriate means is responsible for constantly pushing the heels 8a, with, then without, their bag, towards the curved part 33a of the fingers, in the direction of the upper part of the case 43 of the charger. or store 10 from which the heels 8a will be removed, being easily extracted from the fingers 33 by the notch formed in the holes 8c by the line 8b.
  • the loader or magazine 10 is adjustable in translation and is designed according to the type of sheet elements to be put in place, the presentation of the elements being always the same, that is to say with the elements stacked flat and the stack placed perpendicular to the hypocycloidal approach path of the gripping suction cup (s) in the vicinity of the cusp point of the bag gripping station.
  • the invention is not limited to the embodiments shown and described above but on the contrary covers all the variants in particular as regards the nature, shapes, dimensions of the sheet elements to be assembled or fixed on a support. dish of any type, nature, shape or size whatsoever.
  • the gripping and transport system mounted on the member 12 can be arranged differently with a single suction cup or more than two suction cups arranged in any configuration.
  • a number of bars 13 and therefore of suction cup holders 12, different, less than or more than three, may be provided and several stores 10 may also be provided if space permits, provided that several sets of members are also provided, such as 24 to 29 and 34 to 38 to control the various hypocycloidal trajectories and the detachment of the bags to the various stores.
