Definitions

  • the present invention relates to a paper turning device for back-to-front printing.
  • Such devices are generally known and are intended to be arranged on the paper travel path between two printing groups so that the paper is printed on the urea of its faces, for example the back, in the first group of printing, then either returned by the turning device, and finally printed on its opposite side, for example the front, in the second printing group.
  • the reversal of the sheet is carried out by means of a set of reversal bars which are angularly offset from each other. It is most often a set of four bars, offset at 45 ° from each other, which make it possible to subject the plane of the paper to four successive rotations of 45 °.
  • the known devices however have a certain number of drawbacks since they are non-removable, difficult to access and clean, and that they cannot be adjusted according to the width of the paper to be turned over.
  • the present invention relates to a paper turning device for back-to-front printing which precisely makes it possible to avoid the abovementioned drawbacks.
  • the device comprises a fixed support forming a horizontal slide and extending perpendicular to the path of travel of the paper, and a removable vertical frame supporting the set of turning bars and able to be adjusted in position. and secured to the support.
  • the support slide affects an inverted T-shaped section and the frame is provided at its lower part with at least two nipples each movable vertically under the action of a lever for cause the frame to be attached or detached from the support.
  • the slide support extends over a length greater than twice the maximum width of the paper, so that the frame can be moved between a retracting position where it is outside the path of paper movement and a service position, adjustable according to the width of the paper, where the frame is on the paper travel path.
  • the paper turning device 10 is intended to be placed on the running path of a paper 12 between two printing units 14 and 16.
  • the paper 12 which runs next the direction indicated by the arrow F is printed on one of its faces, for example the back, in the first group 14, is then returned by the device 10 and is then printed on its opposite face, for example the front, in the second group 16.
  • the device 10 comprises a fixed support 18, carried by a frame 20, which forms a horizontal slide and which extends perpendicular to the path of travel of the paper, and a removable vertical frame 22 supporting a set of turning bars and able to be adjusted in position and secured to the support 10.
  • the frame 22 is a generally rectangular frame which comprises a lower arm 24, an upper arm 26 and two vertical uprights 28 and 30.
  • the lower arm 24 is provided with means, which will be described later, allowing the frame to slide in the slide of the support 18 and move it between a retracted position ( Figure 2) and a service position which is itself adjustable ( Figure 4 and Figure 5).
  • the upper arm 26 is provided with rings 32 and 34 which make it possible to lift the frame by means of a lifting device 36 to allow the frame to be placed on different supports on the same printing machine or else on a other printing machine of the same type.
  • the set of turning bars supported by the frame 22 includes a first horizontal deflection roller (this roller is not visible in FIG. 2 because it is hidden by the deflection roller 46 described below), a first oblique bar turning 38, a vertical turning 40, a second turning slash 42, a horizontal turning 44 and a second horizontal turning 46.
  • the two horizontal deflection rollers are supported at the level of the lower arm 24, while the oblique bars 38 and 42 are arranged near the diagonals of the rectangle and that the inversion roller 40 is disposed near the upright 30 and that the turning roller 44 is arranged near the arm 26.
  • the two return rollers, such 46, and the turning rollers 40 and 44 are rollers idly mounted on their respective axes.
  • the roller 40 can, as a variant, be driven at the running speed of the sheet of paper.
  • the bars 38 and 42 are blowing bars, that is to say hollow bars provided with holes and connected to a source of compressed air so as to provide an air mattress around the bars to allow the sliding the sheet of paper.
  • the bar 38, the roller 40, the bar 42 and the roller 44 are arranged successively at 45 ° from one another so as to subject the plane of the sheet of paper to four successive rotations of 45 °.
  • the support 18 comprises a slide 48 which affects an inverted T-shaped section and which opens onto the horizontal surface 50 of the support 18.
  • the slide 48 serves to guide two studs 52 which are provided at the lower part of the frame 22 and which are each vertically movable under the action of a lever 54 to cause the soli darization or separation of the frame 22 on the support 1 8.
  • Each of the handles 54 has an internal thread capable of cooperating with an external thread of the corresponding stud 52.
  • the pin 52 is either raised or lowered, which causes the connection and the separation of the frame and the support respectively.
  • the support 18 extends over a length greater than twice the maximum width of the paper (the paper 12 is shown with its maximum width in Figures 2 and 5 ) so that the frame 22 can be moved between a retracting position (FIG. 2) where it is located outside of the paper travel path and a service position (FIG. 4 or FIG. 5) adjustable according to the width paper, where the frame is on the paper path.
  • the support 18 includes a portion located above the frame 20, below the paper 12, that is to say on the normal path of travel of the paper, and a portion located at the door overhang with respect to the frame 20, this cantilever portion being supported by a forestay 56.
  • the support 18 comprises, at one of its ends, a stop 58 limiting the movement of the frame 22 in the retracted position (cf. FIG. 2) and at its opposite end, a position adjusting member 60 capable of acting moving the frame to adjust the service position (see Figures 4 and 5).
  • the adjusting member 60 comprises a threaded rod 62 directed parallel to the slide of the support, capable of being driven in rotation by a lever 64 and cooperating with a nut 66 which can be secured or detached from the frame 22 (cf. FIG. 7).
  • the frame 22 has for this purpose a housing 68 for receiving the nut 66 and a pivoting lever 70 capable of holding the nut in its housing.
  • the inversion device of the invention is used in the following manner.
  • the frame 22 is transported by means of the lifting device 36 from one support to another, either on the same printing machine, or from one printing machine to another.
  • the member 60 can be operated to adjust the frame to a precise position.
  • This adjustment in position can be facilitated by providing a strip (not shown) on the frame and an index (not shown) on the support.
  • the adjustment in the service position is intended to take account of the width of the width, it being understood that the paper must always be centered relative to the frame and that one of the edges of the paper must always have the same alignment.
  • the inversion device of the invention can thus be easily installed between two printing units to then be placed in an adjustable service position as a function of the width of the paper or in a retracting position. This therefore results in a great flexibility of adaptation since the two printing groups can be used either to make the back-front with different widths, or to make two successive front-to-front printing, the turning device being retracted.
