Definitions

  • the invention relates to a machine for printing the external surface of containers in general, for example bottles, or phials, made of glass, plastic or other material.
  • Prior art comprises silk-screen decorating machines for decorating containers provided with a flat screen under which the containers to be decorated are sequentially carried.
  • both the containers and the screen are supported by members suitable for causing each container to move along a path corresponding to a portion of the extension of the lateral surface of the container while the container is kept tangent to the screen, so that a doctor blade, sliding on the opposite side of the screen, may progressively transfer the ink on the above-mentioned lateral surface through open meshes of the screen defining a desired pattern to be printed.
  • An object of the present invention is to remarkably simplify printing systems on containers in general.
  • a machine for printing containers comprising a printing unit suitable for interacting with containers to be printed, said containers being grasped by respective support means, characterized in that, said printing unit comprises a printing roller externally provided with cavities suitable for containing fluid printing means to be transferred by contact to regions of external surface of said containers.
  • a method for printing containers comprising arranging containers to be printed on support means, bringing the external surface of said containers in contact with printing means for printing said external surface, characterized in that, said containers are brought in contact with said printing means by advancing said containers along a pre-established path.
  • a machine 1 comprises a carousel structure 2 suitable for being indexed at angular steps around a vertical axis Z and comprising a plurality of support arms 4 radially arranged and mutually spaced by an angle of 15°.
  • each arm 4 On the circumference of the carousel structure 2, at the stop regions of the end of each arm 4, five operating units 12 are sequentially arranged each comprising a heating station 6 for heating the containers 7 supported at the end of each arm 4, a printing station 8 for printing the containers 7 and a drying station 10 for drying the printed containers.
  • Each of the various operating units 12 may be designed for printing one colour, so that the overall pattern printed on the containers 7 may comprise five colours.
  • various operating units may be prearranged for printing different faces of a same container 7, so that up to five different faces of a same container 7 may be printed.
  • the containers 7 are sequentially advanced by the arms 4 to the stations 6, 8, 10 of the various operating units 12 while the arms 4 are angularly indexed of an angle of 15° in the direction shown by the arrow F.
  • one or more loading stations 14 are provided arranged for receiving, manually or automatically, on the arms 4 containers 7 to be printed.
  • one or more unloading stations 16 are provided arranged for removing, manually or automatically, from the arms 4 the containers 7 already printed.
  • a filling station 18 for filling the printed containers 7 may be provided upstream the first unloading station 16.
  • each heating station 6 for heating the containers to be printed comprises heating means 14 suitable for modifying the molecular structure of the containers 7, if the containers are made of plastic material, and for preparing said container 7 to receive printing means, such as ink or glaze, in the following printing station 8 in such a way as to prevent said ink or glaze from being detached subsequently from the container 7.
  • heating means 14 suitable for modifying the molecular structure of the containers 7, if the containers are made of plastic material, and for preparing said container 7 to receive printing means, such as ink or glaze, in the following printing station 8 in such a way as to prevent said ink or glaze from being detached subsequently from the container 7.
  • Each printing station 8 comprises a printing roller 16 having an axis parallel to the axis of the container 7 facing the roller 16, that is vertical, the printing roller being provided on its outer surface with small cavities (not shown) into which the printing means is confined by the action of a doctor blade 18a, kept adjacent to an outer generatrix of the printing roller 16, which removes the exceeding amount of the printing means poured in a region 19 immediately upstream the doctor blade with respect to the rotating direction F1 of the printing roller 16.
  • Each drying station 10 comprises drying means 20, for example UV lamp drying means, arranged for drying the printing means distributed on the surface of the container 7 in the printing station 8 arranged immediately upstream.
  • drying means 20 for example UV lamp drying means, arranged for drying the printing means distributed on the surface of the container 7 in the printing station 8 arranged immediately upstream.
  • the containers 7 have external surfaces to be printed comprising an oval or elliptic section 11, the containers 7 are not rotated around their respective longitudinal vertical axis, as it will be better described below.
  • a container 7a has a cylindrical external surface which has to be printed on the whole circumferential extension thereof, the container 7a is rotated around a longitudinal vertical axis thereof according to a direction shown by the arrow F2, opposite to the rotating direction F1 of the printing roller 16.
  • heating means 14 of the heating station 6 is shown, said heating means 14 being mounted on a slide 21 supported by a bed 22 of the machine 1 and actuated to slide in radial direction through motorized means 24 for allowing the heating means 14 to be adjustably positioned with respect to the external surface of the containers 7, 7a to be printed.
  • the arms 4 comprise lower portions 26 connected to a central hub 30 and upper portions 28 vertically adjustable with respect to the hub 30.
  • the lower portions 26 end with lower cradle means 32 suitable for receiving a bottom lower end of the containers 7, 7a and suitable for being rotated by a respective motor, not represented.
  • the upper portions are actuatable by means of operating cylinders 34 so as to be able to engage and disengage, with a tip 36 with which they are provided at the end facing the containers 7, 7a, a neck portion of the containers 7, 7a.
  • a printing station 8 comprises more in detail a motor 38 for rotating the printing roller 16 vertically adjustable by means of an adjusting motor 40 and a respective adjusting screw 42.
  • the assembly of printing roller 16 and respective members of actuation 38 and adjustment 40, 42 is mounted on a slide 44 which comprises at the upper side a collecting tank 46 for collecting the exceeding printing means, the slide 46 being radially actuatable by means of a motor 48 and a respective adjusting screw 50. Therefore the printing roller 16 may be moved close and away with respect to the container 7, 7a.
  • the drying means 20 of a drying station 10 similarly to the heating means 14 and the printing roller 16, is supported by a radial slide 21' which is actuated by a motor 24' through a screw 25'.
  • the machine 1 may work according to two distinct cycles, a continuous cycle and a step-by-step cycle.
  • the carousel 2 is continuously moved around the axis Z, the container 7 is blocked on the cradle 32 and therefore the printing roller 16 is permanently in motion, but it is synchronised with the movement of the container 7, 7a so that, when the container 7, 7a approaches the printing roller 16, the printing roller 16 may tangentially couple with the external surface of the container 7, 7a so printing said surface.
  • the printing roller 16 may be moved, if necessary, along the slide 44 by actuating the motor 48, or through a pneumatic cylinder or a pressure spring, or other equivalent systems.
  • the carousel 2 is indexed along the direction of the arrow F and stops the container 7 in the printing station 8 in which the container is rotated around a longitudinal axis thereof according to the direction F2, while the printing roller, kept in tangential contact with the container 7, rotates in a opposite direction according to the direction Fl.
