Definitions

  • the present invention relates to a method and a device for packaging bottles in a vertical position.
  • the lot withdrawn necessarily comprises an odd number of rows so that, when two beds are superposed, the bottles of the upper bed are placed between the necks of the lower bed, a sampling of lots comprising an even number of rows would require adjusting the transfer movement of each bed, which is not possible in a simple way for a robot arm.
  • the robot arm which collects, transfers and stacks the beds, comprises grippers which are in the form of a sleeve which covers each neck of the bottle of the batch in question. These sleeves are pneumatically tightened on the necks for transporting the bottles.
  • the mounting of each gripper on the robot arm is flexible and tolerates an inaccuracy in the position of the bottle of a few millimeters, which determines the limits of adaptation of the system.
  • the sequencing of the bottles does not always operate in a perfect manner.
  • hazards due to spontaneous jamming (bracing between bottles) or especially to friction between bottles and along the edges of the conveyor which are essentially variable, in particular due to the presence of labels on the bottle.
  • the location of the last bottles of the batch depends on the dispersion of the sides in the stack of, for example, eleven rows of bottles, dispersion depending on the manufacturing tolerances of the bottles, the presence of foreign bodies between the bottles (labels peeled off, crumpled and inserted in the batch ).
  • the invention intends to remedy these drawbacks by proposing a method and a machine which take into account size dispersions, which reduce the risks of blocking or jamming of the bottles during their conveying, and which include means for easily adapting to the different types of bottles encountered.
  • This method also includes a step of transferring the bottles between the sampling step and the depositing step during which the rotation and approximation steps are carried out.
  • the second object of the invention is a device for implementing the above method comprising a plurality of gripping members carried by the end of an arm movable horizontally and vertically between a sampling station and an unloading station on a base or intermediate support for the bottles of each batch, in which the arm is provided with a support fixed relative to the arm, the support carrying several beams which extend transversely to the lines of bottles when the support is above of the sampling station and which can slide parallel to themselves on guides carried by the support, each beam comprising a plurality of plates mounted to rotate in the beam around vertical axes spaced from each other by a distance equal to that separating the axes of the rows of bottles, each plate comprising a pair of gripping members arranged symmetrically with respect to one another the corresponding axis of rotation.
  • a drive member is coupled to the beams to move them between a first position where they are spaced from each other and a second position where they are brought together.
  • this motor member comprises a jack coupled between the two end beams and members for transmitting the movement of the end beams to the intermediate beams, which constitute the beam spacer member between them in each of the two positions.
  • the plates carried by a beam are connected by an eccentric finger to a common rod for operating their rotation coupled to a control jack by a driving cleat and the common rod is coupled to a set of two antagonistic springs, which maintains it, in the absence of effort from the jack, in a middle position corresponding to an alignment of the grippers perpendicular to the parts.
  • FIG. 1 represents, seen from above, the end of a horizontal conveyor 1, having a final stop 2 on which, in the direction A of advancement of the conveyor, the bottles 3 come to stop.
  • the bottles 3 are guided in corridors 4 whose edges 5 are sufficiently wide (or in two parts with adjustable spacing) so that the axes of these corridors are distant from each other by a value e substantially equal to ⁇ 2 times the diameter d of the bottle.
  • the bottles therefore form parallel rows of contiguous bottles.
  • the batch of bottles to be sampled consists of a plurality of rows R1, R2 Vietnamese bottles, one row consisting of bottles of the same level in each row. Once this sample has been taken, we go to the process step of printing a rotation on the bottles to obtain the organization shown in FIG. 2.
  • the third step of the method according to the invention then consists in bringing the pairs of nested rows together in order to obtain the organization of FIG. 3.
  • FIG. 3 is a diagram seen from above of the first bed made.
  • the risks of poor grip are very significantly reduced for several reasons.
  • the bottles are picked while they are online. Their installation in line is much less hazardous than the natural staggered arrangement, because it is done in corridors where only one bottle can engage.
  • the dispersion of dimensions (diameter of the bottles) only has an effect in one direction: the axis of the queue, while for the sampling of bottles already staggered, the dispersion of dimensions is multidirectional in the plan.
  • the effects of cumulation in all these directions can lead to a greater overall offset than the online offset of the last bottle in the batch relative to the gripper.
  • the latter also has by construction sufficient flexibility to absorb this offset.
  • the result of this mechanization of staggered bottles is a very significant reduction in the risks of machine malfunction putting implement the process.
  • Figure 4 illustrates a schematic top view of such a machine which is very similar in its general architecture to known machines.
  • This figure shows the horizontal conveyor 1 for feeding and aligning the bottles at the sampling station 10.
  • the bottles accumulate there in file against the stopper 2.
  • a transfer arm 11 is mounted rotating around an axis vertical 12 on a base 13 and carries at its free end a device 14 provided with grippers at its lower part whose gripping function of the necks of the bottles is provided by known means of pneumatic annular bladder type.
  • the arm 11 therefore makes it possible to transfer a batch of bottles from station 10 to loading station 15 (located in the figure under the equipment 14), to which, by conveyor means, reach pallets 16 and from which, by this same conveyor or another, are removed from the loaded pallets 17.
  • the equipment 14 has vertical mobility with respect to the arm 11 for lifting the sampled bottles and depositing them at different levels depending on whether or not the pallet carries one or more beds of lower bottles.
  • the equipment 14 comprises a horizontal fixed structure 20 which is integral with the end of the arm 11.
  • This structure 20 carries beneath its underside fixed guide bars 21 on which beams 22 can slide (by means of bearings 23). These beams are therefore transverse to the sliding bars 21.
  • Two end beams 24 and 25, parallel to the other beams 22, are integral with rods 26, 27 which slide in fixed bearings 28, 29 integral with the structure 20. This arrangement allows the length of the bars to guidance to be as short as possible, that is to say of length substantially equal to that of all the beams in the tightened position against each other.
  • FIGS 7 and 8 there is shown in isolation the connection of the beams 22, 24 and 25 between them and to an actuating cylinder 30.
  • This cylinder is coupled between the centers of the two end beams 24, 25.
  • Each of these beams carries a vertical finger 31 which is housed in an oblong slot 32 of a plate 33 secured to the beam 22 which is adjacent to it and which is directed towards the corresponding end beam.
  • This plate 33 is extended on the other side of each beam 22 by a symmetrical part of the previous one with an identical light 32 to receive a vertical finger 31 which is integral with each next beam 22.
  • each beam 22, 24 or 25 is equipped with a plurality lity of lower plates 40, rotatably mounted in the beam around the vertical axes 41, spaced from each other by the distance e separating the rows of bottles, and equipped on their underside with two pneumatic tulip-shaped grippers 42 l one from the other with respect to the axis of rotation 41.
  • the tulips are shown aligned from one beam to the other, the lower plates 40 having their axis perpendicular to that of the beam (see Figure 9).
  • the plates are at an angle, at 45 ° to the beam.
  • the simultaneous rotation of the plates of each beam is obtained by a finger 43, eccentric relative to the axis 41 and carrying a rotating ring 44 on which is fixed a tangent rod 45 for connecting the fingers of the plates carried by the same beam.
  • This rod 45 carries in the middle part a fixed jumper which overlaps a cleat 47 for driving with a possibility of sliding between them in a direction perpendicular to the rod.
  • This cleat 47 is, in the device shown, located above the rod 45 and is integral with a rod 48 of cylinder 49, with double effect.
  • This cylinder rod 48 is associated - see FIG.
  • the apparatus described with reference to FIGS. 4 to 10 makes it possible to implement the method of the invention and to adapt this implementation to the main types of bottles encountered. It also allows, thanks to the adjustment possibilities it offers, to form beds of contiguous or spaced bottles and thus respond to all requests. Finally, it allows the reorganization of the bottle lot sampled during its transfer from the sampling station to the loading station.
