Definitions

  • the invention relates to a device for the automatic cleaning of the rubber-covered cylinders, hereinafter referred to as the printing cylinders, of printing machines, of the offset or other type.
  • Devices of this type are known from European patent applications 0025806, 0291745 and 0299193, and from the document US-A-4.344.361, all of which provide for the supply of liquid detergent to a cloth unwound from a reel and taken up on a powered roller. This cloth, with the detergent, is pressed against the printing cylinder which is to be cleaned by means of a presser parallel to the generatrix of the said cylinder.
  • the devices known from the above documents are distinguished from each other essentially in the different types of pressers used, which may consist of a brush or an elastic membrane which seals a chamber into which compressed air is introduced to deform the membrane so that it presses the cloth against the cylinder to be cleaned.
  • the presser may also be formed from a rubber bar fixed with uniformly distributed contact on a rigid bar which is moved parallel to the axis of the printing cylinder. In this case, advantage is taken of the elasticity of the rubber in compression.
  • Another presser known from Italian patent application B092A-000092, combines the advantages of the preceding known solutions, without having their defects, and consists of a strong rubber membrane fixed in an air-tight way on a chamber in which atmospheric pressure is present initially, and which is formed in a rigid bar which, on command, is moved by suitable means parallel to the axis of the printing cylinder.
  • the present patent application is also intended to protect a special structure for supporting and guiding the presser and for supporting the cleaning fluid spray bar, in order to obtain a rigid and lightweight device.
  • the letter P indicates the presser which, on command, presses the cleaning cloth T against the printing cylinder R.
  • the presser is brought into contact with the cloth T by a strong membrane 4 of elastomeric material, fixed with a perimetric seal on a chamber 3 formed in a rigid bar 1 which, on command, is moved by suitable means 5-105 parallel to the axis of the printing cylinder.
  • the presser constructed in this way is preferably housed in a guide cavity 9 formed in a rigid beam 6 supported and fixed at its two ends by suitable means.
  • housings for the cylinder and piston actuators 5-105 of the fluid pressure type, numbering at least two, which act on the bar 1 with a symmetrical disposition and which, on command, cause the said movement of the bar 1, bringing it closer to the printing roller R and then moving it away from it.
  • a longitudinal cavity 20 open on the front of the presser in which cavity is housed a bar 21 with the nozzles 24 which spray the cloth T with liquid detergent, before the cloth reaches the presser and the printing cylinder.
  • the chamber 3 is delimited by at least two longitudinal edges which are raised and coplanar with each other, in which are formed, in a median position and longitudinally, continuous grooves 107-207 of suitable shape and size.
  • the grooves 107-207 have a rectangular or square section, but they may be shaped differently and for example may have a dovetail section, with the side walls converging together towards the outside of the groove.
  • the chamber 3 is temporarily filled with a separating insert, after which the membrane 4 is fixed by vulcanization on the suitably cleaned and ground raised edges of the said chamber, part of the membrane engaging in the said grooves 107-207, preferably filling them completely, so that the said membrane is securely fixed with its longitudinal edges to the corresponding edges of the chamber 3 and not to the said separating insert, which is removed at the end of the fixing phase.
  • the lengths of the bar 1 and of the chamber 3 are appropriately greater than that of the printing roller to be treated, so that end portions of a certain length of the membrane 4 do not come into contact with the printing cylinder.
  • the chamber 3 has a width S greater than the width S1 of the plan projection of the working front portion of the membrane 4, this portion coming into contact with the printing cylinder.
  • the depth H of the chamber 3 is greater than the maximum value of the deflection which the lower face of the membrane 4 undergoes when in contact with the printing roller, as specified subsequently with reference to Figure 9.
  • the marginal parts 104 of the front surface of the membrane 4 are rounded and inclined to form a bevel, so that these parts do not come into contact with the printing cylinder except in transit over the recessed areas of the cylinder, where they form an effective guide.
  • the median part 204 between the said marginal parts 104 may be flat, as illustrated in the drawings, or may have a slight transverse convexity towards the outside, symmetrically with respect to the edges of the chamber 3.
  • the chamber 3 has a width S of 18 mm and a depth H of approximately 2 mm.
  • the width S1 of the active front surface of the membrane 4 is of the order of 14 mm.
  • the thickness of the membrane 4 is approximately 4 mm in the central area and approximately 2.5 mm at the perimeter.
  • Each of the grooves 107-207 has, approximately, a width of 3 mm and a depth of 2 mm.
  • the width of the raised edges of the bar, in which the said grooves 107-207 are formed medially, is approximately 6 mm.
  • the letters Mf indicate the bending moment of the section of the membrane 4 when the membrane interacts with the printing cylinder R.
  • the sum of the end areas A1-A2 in the graph in Figure 8 is equal to or greater than the median area A3 in the same graph, so that, when the presser is removed from the printing roller and when the contact between this roller and the membrane 4 ceases, the membrane returns elastically to the original position.
  • the force exerted by the membrane on the printing cylinder is of a uniformly distributed type, as indicated by the arrows 10 in Figure 7.
  • the invention primarily consists in the provision of a presser designed for the specific use described above and in which advantage is taken of the elasticity of a rubber membrane securely fixed at least with its longitudinal edges to corresponding supports, this membrane, when in contact with the printing cylinder, being subjected to composite stresses, predominantly compressive, bending and tensile stresses.
  • the chamber 3 may be open at the ends.
  • the invention also consists in the provision of a presser in which advantage is taken, in combination with the said elasticity of the membrane, of the effect of the pneumatic counter-pressure 110 (Fig. 7) to which the membrane is subjected when it is mounted with an air-tight seal on the chamber 3 and when the ends of the said membrane are also fixed with an air-tight seal to the corresponding ends of the support bar 1.
  • the ends of the chamber 3 may both be open to permit the extraction of the said insert from either of them. These ends are then closed with suitable plugs, fixed for example by vulcanization and made wholly or partly from the same material from which the membrane is made.
  • one end of the chamber 3 may be covered by a raised edge integral with the bar 1, and coplanar with the longitudinal edges of the chamber 3, and provided with a transverse groove 307 which is connected to the said longitudinal grooves 107-207, while the chamber 3 is open at the other end.
  • a blocking insert which projects from the open end of the chamber is housed in the said chamber 3.
  • the membrane 4 is fixed to the three consecutive edges of the bar 1.
  • the insert is removed from the chamber 3 and the open end of the said chamber is closed with the corresponding end of the membrane by the fixing of a plug 11.
  • the ends of the membrane 4 are also provided with roundings 104 which are joined to the said longitudinal roundings.
  • the bar 1 may be formed from at least two parts, of which one part, indicated by 101, has an annular shape and has a continuous front annular groove 7, into which the membrane 4 is fixed perimetrically by vulcanization.
  • the part 101 is sealed by means of a plug which is provided with anti-cavitation valves and which will be removed subsequently.
  • the part 101 is associated with a part 201 which completes the formation of the bar 1 to hold the movement actuators 5 and which seals the pressure chamber 3 from below and delimits its volume.
  • the parts 101-201 may be fixed together with screws 12 and with a seal 13, the whole being carried out in a way which can be understood and easily performed by those skilled in the art.
  • P2 P1xV1/V2
  • P2 the pressure generated by the compression of the air in the chamber 3
  • P1 the internal resting pressure of the chamber 3 and is equal to atmospheric pressure
  • V1 and V2 are the volumes of the chamber 3 at rest and in the operating condition in Fig. 7, respectively.
  • P P2 - Patm
  • the bending moment Mf* to which the section of the elastic membrane 4 is subjected with the chamber 3 sealed and air-tight is less than or equal to the bending moment Mf of the said membrane section disposed on a chamber 3 open to the outside and therefore always at atmospheric pressure.
  • the pressure P2 is greater than the atmospheric pressure Patm and is less than or equal to the pressure which would be present inside the chamber 3, if the elastic resistance of the membrane 4 is assumed to be zero.
  • F the load uniformly distributed on the presser
  • fmax the maximum deflection of the beam 1 at the supports
  • H-L-S are the initial height or depths of the chamber 3
  • the length and the width of the said presser chamber respectively.
  • fmax x C H which describes the optimal range of application of the presser as a function of the maximum deflection fmax, the penetration C of the membrane 4 and the height H of the chamber 3.
  • the invention also relates to a device which has a presser of the type described above and which, as will be seen in Figures 1 and 4, comprises a beam 6, preferably made of light alloy, fixed by its ends to side plates (not illustrated) which can be fixed to the base of the printing machine and can be disposed to support rotatably the cleaning cloth feed and winding shafts.
  • a presser of the type described above and which, as will be seen in Figures 1 and 4, comprises a beam 6, preferably made of light alloy, fixed by its ends to side plates (not illustrated) which can be fixed to the base of the printing machine and can be disposed to support rotatably the cleaning cloth feed and winding shafts.
  • the bar 1 of the previously described presser is fitted in this housing with the possibility of movement parallel to the said axis.
  • the housings for the presser actuators 5-105 are formed in the beam 6.
  • Two holes 10 with steps 110 are formed in the base of the housing 9 and open perpendicularly and in positions symmetrical about the centre.
  • a bottom plug 11 which bears on the annular step 110 is supported in each of these holes, and has passing through it axially the rod 205 which is screwed at one end 1205 into the bar 1 of the pusher and has an integral piston 2205 at its other end.
  • This piston 2205 slides with the annular seal 14 axially and with an air-tight fit in the hole 10.
  • the number 15 indicates a spring which is interposed between the base cup 11 and the piston 2205 and keeps the presser normally in a withdrawn position.
  • the number 16 indicates a plug which, by means of the seal 17, closes the hole 10 and makes it air-tight and is kept in place by an annular stop 210 and a circlip 18, while it is provided with a threaded through hole 19 for connection to the compressed air supply circuit.
  • the number 100 indicates a vent hole which connects that part of the hole 10 containing the spring 15 to the atmosphere.
  • the base part of the cavity 20 houses a metal bar 21, in whose base wall channels 22 are formed by milling which carry the cleaning liquid to a plurality of equidistant through holes 23 which terminate in corresponding enlarged threaded holes 123 into which the supply nozzles 24, provided with sealing rings 25, are screwed.
  • the various branches of the said channels 22 have suitably differing depths and/or widths.
  • the channels 22 start at one end of the bar 21, where they are connected by means of a perpendicular hole 26 to a longitudinal hole 27, into which is screwed a cylindrical sleeve (not illustrated) which passes through a hole in the end of the beam 6 and provides the connection to the cleaning fluid supply circuit.
  • the bar 21 is inserted into the cavity 20 with the interposition of a flat seal 32, provided with holes for the passage of the screws (not illustrated) which fix the bar 21 to the beam 6.
  • the material forming the beam 6 is distributed towards the outside with respect to the centre of gravity of the section (point of passage of the neutral axis) and consequently the moment of inertia is large. In this way, for a given weight, the structure is more rigid than in known solutions with a small moment of inertia.
  • the membrane 4 of elastomeric material of the presser is provided on its inner surface delimiting the chamber 3, with a reinforcing thin sheet of spring steel 30, which reaches preferably at least to the bottom of the grooves 107, 207.
