Definitions

  • the present invention relates to the grouping of unit dose containers, these containers being for example intended to contain dairy products, for example yogurt or the like.
  • Document FR-A-2,432,975 describes a method of grouping unit dose containers, each container being terminated at its upper part by a flange whose outer contour is polygonal, this method comprising the assembly of two sides edge to edge by using part of the two flanges as a reserve of material.
  • This document also describes the formation of lips at the edge of the flanges. This process is such that the assembly can be carried out by thermocompression, by ultrasonic welding, or by means of an adhesive.
  • Such a method is particularly advantageous because it allows the grouping by two, three, four or six for example of individual containers which can carry an impression on their entire periphery. In this way, this decoration is attractive and gives a very good advertising impact.
  • Document DE-B-1,248,537 also discloses a device for folding and shaping packaging cutouts, in particular allowing the introduction of the objects to be packaged into the packaging and the evacuation of completed packages.
  • the invention has for object the grouping of the objects themselves (which are in particular containers).
  • the present invention relates to an apparatus for grouping unit dose containers, implementing the method described in document FR-A-2,432,975 which constitutes an improvement.
  • the devices for individually holding the containers of the plates each comprise an elastic membrane intended to cooperate with the internal surface of a container, near the flange.
  • the elastic membrane is advantageously in the form of a half-torus with an external diameter normally smaller than that of the internal surface of the containers, and it is mounted between two discs with which it delimits a chamber; when the chamber is emptied of the air it contains, the two discs come together and push outwards the membrane which can then come to bear against the internal surface of a container.
  • At least one of the first and second transfer devices comprises a container support plate, intended to oscillate between a first position for taking up containers and a second position for placing containers in front of the device for hold, the turntable about 90 ° between these two positions; the plates can be moved radially so that the plate which is at the first work station moves away from the axis of the drum and houses these holding devices in the containers.
  • the tray of the transfer device is mounted on movable rods each in a plane perpendicular to the axis of the drum; these rods are fixed to a guide shaft parallel to the axis of the drum and whose movement is guided by a cam surface formed in a plane perpendicular to the axis of the drum.
  • the rods can also slide in a pivoting shaft, parallel to the axis of the drum, the oscillation of the plate being controlled by a second driven pivoting shaft which protrudes from a movable arm in a plane perpendicular to the axis of the drum, this arm being intended to slide freely in an orifice of the guide shaft but being forced to rotate with the second pivoting shaft.
  • the grouping device advantageously comprises a movable plate between a position for releasing the containers and a working position; this tray carries several assembly devices which can be moved individually between two positions such that, when the grouping device is in its working position, an assembly device ensures an assembly of containers when it is in its first position and does not ensure not such an assembly when it is in its second position.
  • the joining devices are for example heating and compression welding devices, devices ultrasonic welding devices or bonding devices.
  • Container reserves can be either stores or carriers.
  • the apparatus comprises four work stations, and a device for printing a code is placed at one of these stations.
  • the apparatus according to the invention is intended for grouping unit dose containers and, in the description which follows, the example of container considered is a cup intended to contain yogurt.
  • Each container as shown in Figure 3, bearing the general reference 10, comprises a frustoconical body 12 closed by a bottom 14. At the end opposite the bottom, the cup is wide open and is bordered by a flange 16.
  • the flange has a polygonal, square shape in the case considered as shown in Figure 1, the corners of the flange being rounded, however.
  • the central part of the device consists of a drum 18 mounted on an axis 20.
  • the latter which is driven by a suitable geared motor group, spins in bearings 22 carried by the frame of the machine.
  • This axis 20 is secured to the drum, for example by keying (not shown).
  • the drum 18 comprises two end discs 24 and 26 which carry several support plates 28, four in the example considered. These plates are arranged at 90 ° relative to each other, that is to say that they are distributed regularly at the circumference of the discs 24 and 26. Each plate 28 is integral with a bar 30 fitted with sockets balls intended to slide in grooves 32. formed in discs 24 and 26. Cams, not shown, control the radial sliding of the bars 32 and thus of the plates 28, when these are located at a transfer station, as described in the continued with reference to the operation of the device.
  • Each plate 28 carries several mandrels 34 constituting devices for holding buckets 12. These mandrels are shown in more detail in FIG. 3.
  • the plate 28 has a housing which contains a disc 36 having an orifice central 38 which communicates with an orifice 40 in the plate 28.
  • a second solid disc 42 is arranged opposite the first disc 36 and a membrane 44 in the form of a half-torus, as shown in FIG. 3, has its internal edges which are are housed in grooves formed in the two discs 36 and 42, in a sealed manner.
  • the membrane 44 defines with the two disks a chamber 46.
  • the external surface 48 of the membrane has a diameter which is less than or equal to that of the opening of the buckets 10.
  • the disc 42 is pulled towards the disc 36 so that the membrane is pushed back towards the exterior and squeezes the internal surface of the container, near the flange, by its external surface 48.
  • each plate 28 has several mandrels 34, twelve in the embodiment shown in FIG. 1.
  • FIG. 1 also represents a store 50 of individual containers of unit dose, stacked as indicated in FIG. 1 in twelve stacks or any other multiplied number of packs to be produced (number corresponding to the number of mandrels of the plates 28), the store being formed in an orifice of a plate 52 which carries rods 54 for guiding the stacks of containers.
  • FIG. 2 It should be noted that the containers are. normally kept in the store by a device which holds the lower containers,
  • This transfer device comprises a plate 56 which, as indicated by the reference 58 in FIG. 2, includes a device intended to retain the cups 10. They may, for example, be simple suction cups.
  • the plate 56 is mounted on rods 60 which pass through holes 62 of a guide shaft 64.
  • This shaft 64 is parallel to the shaft 20 which carries the drum and, at at least one of its ends, it is mounted in a branch of a stirrup 66, by means of a bearing 67.
  • the another branch of the stirrup 66 carries an axis 68 aligned with the shaft 64 so that, in the remainder of this specification and in the claims, the expression “guide shaft designates the assembly formed by the shaft 64 and the axis 68.
  • the latter carries a roller 70 intended to roll on a cam surface 72 formed in a plate 74 fixed to the frame and disposed in a plane perpendicular to the axis 20 of the drum.
  • the stirrup 66 has, in its middle part, a pad 76 allowing the sliding of an arm 78 fixed by a clamp 80 to a driven pivoting shaft 82.
  • This shaft 82 can pivot in bearings 85 fixed on the frame. It is controlled by a drive device shown in Figure 2.
  • a pinion 83 is integral with the shaft 82 on which it is for example keyed, and it cooperates with the teeth of a rack 84 controlled by the drive mechanism of the device .
  • the rods 60 can also slide with respect to another pivoting shaft 86, in bearings 88 housed in holes in this shaft.
  • the tree 86 journals in bearings 90 carried by the frame.
  • the guide shaft 64 lowers in a vertical plane and also lowers the buckets 10 which are thus separated from the bottom of the stacks of the magazine 50 since a device holds the following containers.
  • the cam arrives in its inclined intermediate part so that the rods 60 pivot around the axis of the shaft 86 and lower in a horizontal position, as shown in broken lines in FIG. 2.
  • the roller 70 then reaches the part of the cam surface 72 which is substantially horizontal so that the continued rotation of the driven shaft 82 causes the plate 56 to advance towards the mandrels 34, perpendicular to the tray 28.
  • the cups 10 carried by the plate 56 are fitted onto the mandrels which can then be connected to a vacuum source so that they hold the cups.
  • the suction of the plate 56 is then eliminated so that the buckets remain on the mandrels 34 while the plate 56 departs and returns to the position shown in solid lines in FIG. 2, during a sequence of operations opposite to that just described.
  • the horizontal part of the cam surface 72 allows the movement of the plate 56 so that it comes to place the cups on the mandrels 34. This characteristic is not essential because, when the plate 28 can slide in the grooves 32 as indicated above, it is the plate 28 which can advance to accommodate the mandrels 34 in the buckets.
  • the apparatus may include one and / or the other of these characteristics although both have been described.
  • This comprises a plate 92 placed above the second work station B (the four work stations of the machine shown are identified by the references A, B, C and D).
  • This plate 92 can slide on rods 93 and it carries rods 94, the upper end of which is secured to jacks 96 of a suitable type.
  • the lower end of each rod 94 carries a welding comb 98.
  • These combs are for example heated by heating rods connected to a temperature regulator or they can be vibratory devices supplied by an ultrasonic transmitter.
  • the device comprises on the one hand combs substantially parallel to the axis of the shaft 20 of the drum and on the other hand combs substantially perpendicular to this axis.
  • Each comb is intended to link the flanges of two of the adjacent cups 10 carried by the plate 28.
  • Figures 5 to 8 show assemblies of two, three, four and six containers respectively.
  • the references 102 designate zones in which the sides of the flanges are not connected while the references 104 designate the connection zones of the sides of the flanges.
  • the cylinders 96 allow this arrangement. In fact, they allow the combs 98 to rise sufficiently, which must not ensure welding so that these combs do not come into contact with the flanges. In this way, only certain welds are made, and the assemblies can be of the desired type, FIGS. 5 to 8 representing nonlimiting examples.
  • FIG. 2 shows an example of a machine intended to receive the buckets.
  • This machine identified by the reference 108 comprises a chain 110 carrying trays 112 having cells 114 each allowing the housing of a bucket.
  • a device 116 is movable vertically so that, when it rises, it places suction cups 118 carried by rods 120, in contact with the bottom of the buckets 10. The device 116 then lowers and thus guides the buckets in the cells 114.
  • the printing device comes into contact with the bottoms of the cups, carries the appropriate code and departs.
  • the second transfer device 116 rises, grabs the cups placed in front of it and descends by placing the cups in the cells 114, then it releases these cups and moves down.
  • the plates 28 of stations A, B and C carry buckets while the plate of station D does not.
  • the drum rotates a quarter of a turn anti-clockwise in FIG. 2. In this way, the plate devoid of buckets is at station A. The cycle indicated above then begins again.
  • a suitable drive device ensures the synchronization of these movements.
  • This drive device comprises, in one embodiment of the invention, a variable speed drive driving a Maltese cross with four positions which controls the rotation of the drum. The same device controls the displacement in translation of the rack 84, of the plate 92, of the printing device 106 if necessary, and of the second transfer device 116.
  • Such drive devices are well known to those skilled in the art and are not described in detail.
  • FIG. 4 represents a variant in which the only operation carried out is the assembly of the sides of the flanges so that the second transfer device is placed at station C.
  • This second transfer device is completely similar to the first, and we do not not describe it in detail.
  • the references of its elements are identical to those of the corresponding elements of the first transfer device, followed by the sign '.
  • the operation is the opposite of that described above, the grouped containers being finally stacked one inside the other, in a magazine 50 '.
  • the mandrels do not carry any buckets.
