Definitions

  • the subject of this invention is a tunnel, or cover, for printing and/or coupling machines, especially but not exclusively rotogravure machines, which, thanks to its conformation, is easier to use in terms of maintenance and cleaning, operations which create considerable inconvenience in the printing and coupling machine sector.
  • the upper part can only be inclined by a certain angle, meaning that, in correspondence with the hinged area, the space for introducing the cleaning equipment is particularly small and becomes completely non existent near the mechanism that hinges the upper part to the base of the tunnel.
  • This invention regards a drying tunnel for printing and/or coupling machines which eliminates the abovementioned problems by adopting a cover that is not hinged to the main base but can be lifted and moved away from the tunnel in a parallel position.
  • FIG. 1 shows a cross-section of the tunnel in question in the closed position
  • figure 2 shows the view in figure 1, in a schematic longitudinal section
  • FIG. 3 shows a cross-section of the tunnel with the upper cover in the raised position
  • figure 4 shows the view in figure 3, in a schematic cross-section
  • FIG. 5 shows a schematic cross-section of the tunnel with the upper cover raised and moved sideways
  • figure 6 shows the view in figure 5, in a schematic cross-section
  • FIGS. 7 and 8 show a schematic view of the tunnel in the raised and lowered position
  • FIG. 9 shows a schematic view of the tunnel in a horizontally moved position
  • FIG. 10 shows a schematic view of the tunnel in an inclined position
  • FIG. 11 shows an overhead view of a partial section of an example of a roller support
  • FIG. 12 shows the cross-section of the support shown in figure 10.
  • figure 13 shows the sectioned frontal view of the support shown in figure 11;
  • FIG. 14 shows the cross-section of another version of the support.
  • number 1 is used to indicate a drying tunnel for printing and/or coupling machines. It is normally equipped with an upper structure 2 which acts as a cover, and of several different devices for moving and managing rolls 3 of paper and/or film, such as polyethylene. Said devices consist largely of motors 4 and chains 5 and running and guide rollers 6.
  • Said machine comprises, for instance, a first roll 3b, which holds a first film, and a second roll 3b, which holds a second film, and a roll 3c for winding the coupled films.
  • This invention also regards the upper cover 2 of the tunnel, which is housed on the lower part 1 and can be moved vertically and horizontally, allowing said upper cover 2 to be placed in a raised and shifted position compared with part 1 of the tunnel, leaving the latter totally uncovered.
  • said cover can be lifted from the tunnel by at least one, but preferably several, jacks.
  • said cover can be lifted by several front jacks 20, operatively connected to the cover in a frontal area 20a, and by several rear jacks 20, operatively connected to the cover in a rear area 20b.
  • said front and rear jacks can be activated independently, thus lifting the front area 20a and the rear area 20b to different heights.
  • said cover can be inclined, thus creating a cavity 30, usually in a funnel shape, between the inner surface of the cover and the rollers.
  • said jacks 20, 22 can be activated mechanically.
  • said jacks can be activated in a controlled way, commanded from a central control panel which displays the status of the jacks and is used to set new statuses.
  • the printing and/or coupling machine is initially "drawn-in", in other words, the film or the tape to be coupled is introduced into the machine.
  • This operation should preferably be performed by lifting the cover 2 of the tunnel, both in the front area 20a and in the rear area 20b, in such a way so that the cavity 30 is roughly 40 millimetres high.
  • the film to be treated is wound around the first roll 3a.
  • the head of the film, or the free edge, is connected to a drawing-in bar, operatively connected to the drawing-in chains 5, set to the sides of the rollers 6 and suitably moved.
  • the drawing-in bar moves on the rollers 6. unwinding the film from the first roll 3a.
  • the bar reaches the front area 20a of the machine, the film is cut in line with the drawing-in bar and wound, manually or by special winding devices, onto the second roll 3b.
  • the cover 2 is lowered until the cavity reaches a height of between 5 and 40 millimetres, preferably between 8 and 10 millimetres.
  • the ink or adhesive is applied to the film or tape according to requirements.
  • the tape to which adhesive has been applied is subject to a passage of hot air fed into the tunnel by the insufflators 7.
  • the funnel-shaped cavity enables a variation in the air speed and in the conditions of evaporation of the solvent during the introduction of air between the rear area 20b and the front area 20a of the tunnel.
  • a smaller section of the cavity creates a higher air speed and therefore more powerful solvent evaporation, which is advantageous in the tape exit area, while the best conditions in the tape entry area are less powerful in order to avoid the formation of crusts on the adhesive.
  • Another part of this invention is a cradle upon which the rollers used in machines for rotogravure printing and/or coupling to pull polyethylene films rest and in which they move, to restrict revolving friction.
  • the roller 6 has a tang 102, said roller 6, being placed in rotation on a pair of revolving bodies 103, such as an outer ring of ball bearings for example, with a simple rest and gravitational contact.
  • the bearings 103 are hinged and mortised to a main support 104 and their surface is in contact with the tang 102 of the roller 6 made of suitable material, such as special steel with a surface coating of particularly hard material.
  • Said outlet 105 is positioned so that the air flows over the group made up of the roller 6 and the bearings 103 in such a position as to cool the contact area between the roller and bearings, limiting the variation in temperature and the consequent thermal dilation.
  • the tang 102 of the roller 6 has a shoulder 110, preferably in the form of a pair of rings.
  • the roller 6 is guided on just one side, allowing the production of the effects of thermal dilation only on the opposite side which remains free.
  • said version can be used in processes requiring the application of aluminium foil.
  • Maintenance is carried out by activating the machine lifting devices such as jacks 20, 22, lifting the cover to a set height, so that the cover can be horizontally moved.
  • Said horizontal movement devices are activated by moving the cover 2 horizontally to free access to the tunnel.
  • rollers 6 are easily accessible along their whole longitudinal length, consenting simple and quick cleaning.
  • rollers are lifted from the machine, without disassembling any parts as they gravitationally rest on the revolving bodies or bearings 103.
  • rollers are cleaned outside the machine and then reassembled.
  • rollers are replaced with clean rollers already prepared outside the machine.
