Definitions

  • the present invention relates to a device and a method for printing on cylindrical bodies. More specifically the present invention relates to a device and a method for painting or coating, or decorating the side surface of substantially cylindrical bodies, such as for example tubes or bottles made of metal or plastic material, used for example for the storage of food, industrial, hygienic or pharmaceutical past or fluid products, and the like.
  • side surface of the substantially cylindrical body although preferably it is referred to the surface comprised between the bases of the cylindrical body, all of the body surfaces are meant, comprising the base surfaces.
  • Machines for coating cylindrical objects are known in the art, such as, for example, metal cans for beverages, that are provided with a plurality of print heads by which the outer surface of the cylindrical objects is painted and decorated with images, the brand of the product, symbols, characters, etc.
  • one of the most used techniques is the digital ink-jet printing technique.
  • Patent US 6.769.357 describes a method and a machine for decorating cans of two pieces type, by means of a plurality of ink-jet print heads.
  • the cans are moved by a circular rotating plate on which are constrained one or more spindles, on which, in turn, the cans are loaded.
  • every single spindle allows the rotation of the can around its own longitudinal symmetry axis, such that each print head can reach the whole outer surface of the can.
  • the machine is provided with means for loading and unloading the cans from every single spindle and with a painting station positioned downstream of the print heads.
  • EP 2 283 932 A1 shows an inkjet printer for printing on a three-dimensional shape.
  • the decorating device is provided with a further row of print heads arranged in opposite position one to each other.
  • This kind of machine suffers from problems due to the shape of the transport means on which the cans are moved. Specifically, the use of a circular plate on which the spindles are constrained makes the machine structure very complicated, thereby resulting very expensive and difficult to realize, besides obviously being of considerable bulk.
  • the specific arrangement of the print heads along an arc of a circle can determine problems to the correct delivery of the ink besides to the undesired build up or outflow thereof. Specifically, in the embodiment wherein two rows of print heads are present and they are arranged in opposite position one to each other on two arcs of a circle, these problems get worse.
  • the bottom print head will undergo frequent problems of building up of ink and sediments coming from the top print head or from the piece under processing.
  • the object of the present invention is to provide a device, with a corresponding activation method, for printing on the side surface of cylindrical bodies which is able to solve the problems of the known art, and specifically which is easy and cost effective to realize, of small bulk and able to reduce the complexity of means adapted to the displacement of the cylindrical bodies during processing.
  • the object of the present invention is to make less complex the realization and the management of the transport of cylindrical bodies under processing as well as provide transport means for the cylindrical bodies which are easy to control and could be accommodated in a limited space.
  • Present invention concerns a device for printing on a side surface of at least one substantially cylindrical body, according to appended claim 1
  • side surface is herein and hereinafter used to mean all of the surfaces of the cylindrical body, comprising the base surfaces.
  • central axis the symmetry axis of the surface of the body intended to be treated is meant, specifically in case wherein printing on the side surface of a metal tube having cylindrical shape is intended, the central axis of such a surface corresponds to the longitudinal symmetry axis of the cylinder passing through the center of the two base surfaces.
  • the moving of the cylindrical bodies under processing along a straight vertical path with its central axis substantially orthogonal to such a vertical path allows to notably limit the bulks of the print device, to simultaneously process different cylindrical bodies without the need of using kinematic systems providing curved paths to these cylindrical bodies, to simplify the activations of the print head and to readily move the cylindrical bodies themselves, mainly during the coming in and out from the device.
  • the printing device comprises at least a couple of ink-jet print heads, arranged in opposite position one to each other, such that the straight path along which the transport means move the cylindrical body/ bodies is comprised in the space between the two print heads of each couple of print heads.
  • the means for putting in rotation the cylindrical bodies preferably comprise one or more spindles supporting and putting in rotation the cylindrical body around its own longitudinal symmetry axis.
  • the spindles are preferably arranged so that they put in rotation the cylindrical bodies with their central axis substantially perpendicular to the straight vertical path along which the cylindrical bodies are moved.
  • the transport means of the device according to the present invention comprise at least one support, which can be shifted along a straight rail, on which one or more spindles are constrained.
  • the movement of the support/s for the spindles is controlled by means of a linear actuator.
  • each print head delivers ink of one color and due to this reason the device comprises at least four print heads, or couples of print heads, delivering one of the three primary colors and the black, respectively.
  • the cylindrical bodies can be transported in succession in front of the print heads reaching the position wherein the side surface intended to be treated is facing to the print head, or to one or more couples thereof.
  • means for moving one or more print heads are provided at least along a straight direction for at least part of the straight path along which the transport means move the cylindrical bodies.
  • the cylindrical bodies must not be stopped during their movement along the straight path at the print heads to carry out the decoration of their surface.
  • the device is provided with means for moving the print head too which, because of shifting along a straight direction for at least part of the path followed by the cylindrical bodies transported by the spindles, allow to carry out the moving delivery of the ink.
  • the time required for the processing of the cylindrical bodies can be reduced and specifically the positioning mistakes due to the need of repeatedly stopping the motion of the spindles along the straight path at the print heads, or couples of print heads, with the possibility of running into misalignment errors of the surface of the cylindrical body relatively to the print head, can be limited.
  • the appended claim 11 discloses a method for printing on the side surface of substantially cylindrical bodies by means of a printing device according to the above described type.
  • cylindrical bodies can be put in rotation simultaneously with the activation of at least one print head.
  • the method comprises a step wherein the print head is moved to follow the transport movement of at least one cylindrical body for at least one portion of the displacement of the latter along the straight path.
