Definitions

  • the present invention relates to a machine for closing receptacles, in particular made from blanks of cardboard or similar material and made up of a plurality of flaps hinged to each other around fold lines and hinged lower and upper end flaps. respectively to the flaps around fold lines.
  • each receptacle Before their introduction into such a machine, each receptacle has a configuration for which the flaps are folded to form the lateral belt of the receptacle, as well as the lower end flaps to form the bottom of said receptacle, while the upper end flaps , intended to form the upper face, opposite the bottom, of the receptacle, are in the extension of the flaps forming the belt. Products are then generally placed in the receptacle, the upper face of which is open.
  • the receptacles are transferred to the machine, the purpose of which is notably to fold the upper end flaps to close the receptacle and form the upper face parallel and opposite to the bottom.
  • a machine of this type comprises a feed system, driving one by one each receptacle by its bottom which slides on a transport track, and a mechanism for closing the upper end flaps.
  • the advance system comprises, for example, two side chains respectively disposed on either side of said transport track and capable of being moved by a drive member (see document US-A-4,173,921).
  • the two side chains are connected together by bars arranged transversely to the direction of movement of the receptacles and regularly spaced from each other, each of the bars being thus susceptible to come into contact with the rear face of the lateral belt of the receptacle to drive it along the track.
  • a synchronization mechanism connects the advance system to the closing mechanism so that, during the movement of each of the receptacles pushed by one of the transverse bars on the transport track, the closing mechanism acts on the upper flaps to fold them, closing the receptacle.
  • each receptacle to facilitate the movement of each receptacle and to avoid deformation thereof, it is preferable that the corresponding bar comes into contact with the rear face of the lateral belt at a low level of said face, close to the bottom of the receptacle. Despite this, it happens that the side faces of the belt are deformed. In addition, when the closure means act on the upper flaps of each receptacle to fold them back, the front and rear lateral faces of the belt tend to tilt backwards relative to the direction of movement, by deforming .
  • the receptacles obtained then have a deformed appearance which is detrimental to their presentation.
  • the edges of the upper flaps may, once folded, overlap which also affects the quality of presentation of said receptacles.
  • the deformation of the lateral faces may possibly cause damage to the products contained in the receptacles.
  • this type of machine only solves partially the following drawback, generally encountered with the receptacles described above.
  • the receptacles made of cardboard material are flat, that is to say that the lateral belt of each of them is folded, so that the four flaps constituting the belt form two angles substantially zero opposites and two substantially flat opposite angles.
  • each of the bars acting against the rear flap of the receptacle near its bottom makes it possible to straighten the lower part of the receptacle so that its section is, at this level, rectangular.
  • the receptacle always has, at its upper part, a parallelepiped section, the four vertical flaps of each receptacle having a sort of helix profile.
  • the present invention particularly aims to overcome these drawbacks and relates to a machine for closing receptacles by which the receptacles obtained, after folding the upper flaps, have a regular and neat appearance.
  • each of the receptacles moves on the transport track thanks to two transverse bars applying against the rear face of the receptacle at two distinct levels thereof, the lateral faces of the belt of the receptacle do not deform and remain orthogonal to the bottom while being perpendicular to each other. In this way, we obtain, at the machine outlet, closed receptacles whose external appearance, and therefore the presentation, is regular, clean and without deformation.
  • the auxiliary drive system is located above and in correspondence with the advance system, the transverse bars of the drive system being capable of coming into contact with the rear face of the receptacles at a high level, close to the fold line of the corresponding end flap while the transverse bars of the advance system are likely to come into contact with the rear face of the receptacles at a low level, close to the bottom of the receptacles.
  • This arrangement providing an appropriate spacing between the transverse bars of the advance and drive systems which act on the rear face of the receptacles, promotes the displacement of the latter along the transport path while preventing their deformation.
  • the means for synchronizing said advance system with the auxiliary drive system comprise the same drive member and a transmission by chains and toothed wheels connecting said drive member to each system.
  • the machine can include means for adjusting the phase between the advance system and the auxiliary drive system.
  • phase shifting means to move the feed system backward, simultaneously causing the bars to move backwards, so that the bar pushing the rear face of the receptacle to a low level is in phase with that of the drive system auxiliary, the receptacle then being pushed again by the two bars.
  • said means for adjusting the phase between the advance system and the auxiliary drive system act on the advance system.
  • said means for adjusting the phase comprise a controllable threaded rod capable of acting, by means of a compass, pivoting around one of the axes of said transmission, and of intermediate sprockets driven by a chain, on said transmission, so as to impart a movement relative to the chains of said advance system while not driving in this movement the chains of said auxiliary drive system.
  • the advance system and the auxiliary drive system can be moved relative to each other by means of control means, so that the distance separating the bars of each system, when these drive a receptacle, is adjustable.
  • control means act on the auxiliary drive system.
  • said control means comprise a motor driving a screw-nut system to which is linked a chassis carrying the auxiliary drive system.
  • said mechanism for closing the upper end flaps of said receptacles is advantageously associated with the auxiliary drive system.
  • said closing mechanism may comprise two plates, converging in the direction of movement of the receptacles and orthogonal to the transport path, making it possible to fold the end flaps of the faces of the receptacle parallel to the direction of movement, a plate inclined in the direction of movement direction and making it possible to fold the end flap of the front face of the receptacle, orthogonal to the direction of movement, and a set of controllable articulated connecting rods making it possible to fold the end flap of the rear face of said receptacle.
  • said set of articulated connecting rods is advantageously mounted, at one end, on an axis connected, in a parallel and eccentric manner, to an axis of a toothed wheel, which is driven and synchronized with the transmission by chains and toothed wheels.
  • moving said auxiliary drive system and is provided at its other end with a member capable of acting on the upper end flap extending the rear face of each receptacle in order to fold it up.
  • the machine according to the invention may include a system for supplying said receptacles to the transport path.
  • the feed system advantageously comprises a plurality of rollers parallel to each other and orthogonal to the direction of movement of receptacles on the transport track, said rollers being driven in movement by at least one belt surrounding them.
  • This arrangement increases in particular the adhesion of the receptacles on the rollers linked together by the belt and makes it possible to increase, consequently, the rate of dispatch of the receptacles towards the transport track.
  • said rollers are carried by a tilting support which can occupy two distinct positions under the action of a power member, said support being articulated around a fixed axis so that, when the power member is inactive, said rollers are at a lower level of a stop, preventing the transfer of the receptacles towards the transport track, and, when the power member is active, said rollers are at a level higher than that of the stop, allowing the transfer of receptacles to the transport route.
