Definitions

  • the present invention relates to an automatic packaging device, in non-compartmentalized boxes, for food products or the like, of substantially parallelepiped shape, arranged in regular rows.
  • the canning of products of elongated parallelepiped shape is currently carried out by means of machines according to a well defined sequencing in several phases, a phase of bringing and grouping of the products to condition and a transfer phase in the packaging box, for example using a hydraulic articulated arm equipped with an aiming camera and a clamp to grab the products one by one and arrange them in rows made up of 'units superimposed or not in a packaging box.
  • the clamp of the hydraulic arm may encounter difficulties in grasping products, in particular products without packaging, for example frozen pancakes, which does not always make it possible to have the number of products required in each packaging box.
  • the object of the present invention is to remedy these drawbacks by proposing a device for packaging various products, superimposed or not, presented in regular rows, which does not use automated mechanical gripping means, thereby offering greater simplicity of use and better reliability while allowing high rates.
  • the device according to the invention is essentially characterized in that it comprises means for bringing above a first conveyor, transporting packaging boxes, cleats each comprising a support for fixing to said means and a blade intended to be introduced vertically into a packaging box to temporarily compartmentalize it, the time to fill it, the bars to be conditioned being brought by a second conveyor arranged perpendicular to the first.
  • the means on which the cleats are fixed are a chain or a toothed belt stretched between two wheels of horizontal axes, one of which is driving, disposed above the first conveyor, in parallel audit conveyor.
  • the tabs are regularly spaced by a distance corresponding to the pitch of the belt or the chain and to the width of a compartment delimited by a blade and the edge of a box, or by two blades.
  • the device operates as follows: the empty packaging boxes are brought, opening upwards, by the first conveyor, at a constant speed of movement slightly greater than or equal to the speed of movement of the belt or chain, and therefore cleats, up to a stopper located a short distance in front of the first wheel and operating in synchronization by releasing at a determined time a box which is driven by the conveyor and stopped by the first cleat in its path, which, integral with the belt or chain, imposes its speed of movement on said box which therefore advances at a lower speed than the conveyor which slides under it, then n-1 cleats are gradually introduced into the box so as to form compartments .
  • the box When the first compartment arrives at the level of the second conveyor, the box marks a stopping time corresponding to the introduction one after the other of one or more bars which are superimposed in said compartment, the belt or the chain and the box then advance at the same step and the second compartment is facing the second conveyor to be filled, and so on until the box is full, after which it is released by releasing the tabs and evacuated by means appropriate.
  • the cleats are secured perpendicular to the chain and they are removed from the box, after filling, by means of a third conveyor, movable in vertical translation and located at the end of the conveyor main, before the tabs start to tilt when they come into contact with the return wheel and eject one or more products out of the box.
  • the cleats comprise a support which extends beyond the belt, and the ends of the extensions of two consecutive cleats of the same series of n cleats are connected together by a connecting rod, so as to form n-1 deformable parallelograms, the last cleat being secured perpendicular to the belt while the n-1 other cleats are pivotally mounted about a transverse axis.
  • the movable tabs are introduced into the box, forming partitions, and they are removed when they come into contact with the idler wheel, remaining substantially parallel to the last cleat, thanks to the links, which allows them to exit vertically. of the box, the rigidity of the two cleat blades in the box being further ensured by the fixity of the last cleat.
  • all the lugs are movable in rotation about an axis situated substantially at the level of the belt and one of the two ends of the rods is no longer mounted around a pivot axis at the end. an extension but on said pivot axis of the cleats.
  • This type of positioning makes it possible to form right triangles in the rectilinear part of the belt, so that the tabs are perpendicular to the belt, said triangles deforming when the tabs enter the curved part of the return wheel of the belt, this which leaves said cleats in a substantially vertical position their allowing to be released without projecting the products outside the box.
  • the device according to the invention comprises, in this embodiment, a conveyor 1 over which passes an endless chain 2, partially shown, stretched between two wheels drive 30 and 31 of axes 30 ′ and 31 ′ horizontal and to which radially spaced cleats 21 are joined radially 21 and comprising a blade 213 secured to a support 214, intended to be introduced into a box 11, transported by the conveyor 1 progressing at constant speed, in the direction of arrow F, the chain 2 progressing in steps of length equal to the distance separating two consecutive lugs 21, the width of a compartment of said box corresponding to the step of advancement of chain 2.
  • Operation takes place in three phases A, B, C.
  • phase A two tabs 210 and 211 integral with the chain 2 are introduced into a packaging box 11 conveyed by the conveyor 1 towards a stop 13 placed just before the wheel 30 and releasing in synchronization, at regular intervals, a box 11 which abuts against the stopper 212, which retains said box which then advances in step with the chain 2 which then gradually brings the tabs 210 then 211 vertically in said box 11 to temporarily form three compartments 120, 121, and 122, the space between two consecutive cleats corresponding to the pitch of the chain 2.
  • phase B the products are introduced into the compartments 120, 121 and 122 of the box 11, using a second conveyor 5 arranged perpendicular to the conveyor 1 between the two wheels 30 and 31 and above the upper plane boxes 11, transporting food products, or the like, regularly spaced by a distance corresponding to the step of advancement of the chain 2, being in the form of bars 4 to be introduced into each compartment 120, 121 and 122.
  • the first compartment 120 arrives opposite the conveyor 5, it receives two superimposed bars 41 then 42, after which the box 11 advances by one step by means of the cleat 212 secured to the chain 2 and the compartment 121 arrives at the level of the conveyor 5 to be filled as the first of two bars 43 and 44, and so on.
  • Phase C corresponds to the release of the lugs 21 from the box 11 which, when filled, arrives on a third conveyor 8, movable in vertical translation, is lowered by one level so as to release the lugs 210 and 211, which incline in contact with the chain 2 with the return wheel 31, which makes it possible to prevent the tabs 210 and 211 from ejecting the bars 42 and 44 out of the box 11, which is then evacuated by a fourth conveyor 8 '.
  • the device according to the invention comprises, in this second embodiment, an endless toothed belt 6 tensioned between drive wheels 70 and 71 with horizontal axes 70 ′ and 71 ′, the rear wheel 71 being driving, cleats 60 being fixed to the belt 6 to which they are suspended in series of three, regularly spaced and each comprising a support 65 for a blade 66 provided with an extension 67 extending beyond the belt 2, two consecutive tabs 61, 62 and 62, 63 being interconnected, at the upper end of the extensions 67, by rods 9, the last cleat 63 being secured perpendicular to the belt 6 and the other two tabs 61 and 62 being pivotally mounted about a transverse axis 64.
  • This embodiment does not use a third conveyor, owing to the fact that the movable lugs 61 and 62, by means of the connecting rods 9, remain parallel to the cleat 63, so that, when the lugs 61 and 62 meet the wheel back 71, they remain in a vertical position, position imposed by the cleat 63 perpendicular to the belt 6, as long as the latter does not come into contact with the curvature of the wheel 71, which allows the cleats 61 and 62 to come out vertically from the box 11 without touching the bars 4, while the cleat 63 retains the next box by its front face 10.
