Definitions

  • the present invention relates to a device for cleaning cylindrical rollers, with smooth or engraved surfaces, in particular rollers for printing machines, fluid transfer rollers or the like, such as anilox rollers, cliché rollers, spreader rollers, finishers, laminators or other.
  • the invention also relates to a method for cleaning a roller.
  • Machines for printing web materials such as, but not limited to, plies of tissue paper, are subject to frequent downtimes to allow cleaning of the rollers, as ply material tends to easily deposit small particles or fibers of material that, being in contact with the printing liquid (ink), soil or fill the small cells that transfer the ink.
  • ply material tends to easily deposit small particles or fibers of material that, being in contact with the printing liquid (ink), soil or fill the small cells that transfer the ink.
  • the liquid transferred also becoming contaminated with debris from the web material to be printed, tends to stratify inside the cells used to transport the liquid, thereby reducing their capacity.
  • rollers can vary, as can their structure. Therefore, machines have been designed that allow rapid removal of the rollers, in this way allowing them to be washed and cleaned off-line.
  • cleaning systems that operate off-line, i.e., systems in which the roller to be cleaned is disassembled from the production machine, as well as cleaning systems that are installed in-line, i.e., on the production machine, have been developed.
  • the main object of the present invention is to provide a device that is fast, reliable and inexpensive, with regard to the cost of the system and the cost of the consumables.
  • the object of some embodiments is to obtain a cleaning device that can be easily installed, both in-line (i.e., on the machine) and off-line, in any working environment and without requiring particular safety equipment, as it has a small size, low weight, limited consumption of material and reduced cleaning cycle performance times. This means it can also be installed on existing machines with a quick replacement of existing devices, or added to plants without cleaning devices.
  • a cleaning device comprising a cleaning head with a cleaning chamber, in which a mechanical cleaning member is housed, and with which feeding members are associated for feeding a cleaning liquid into the cleaning chamber.
  • the mechanical member and the cleaning liquid dispensed by the feeding members work in combination inside the cleaning chamber to clean the cylindrical surface of the roller to be cleaned.
  • the cleaning head is provided with a translation movement in a direction parallel to the axis of the cylindrical roller.
  • the combination of the rotation movement of the roller and the translation movement of the cleaning head allows the whole of the cylindrical surface of a roller, even with considerable radial and/or axial dimensions, to be washed efficiently in a small space.
  • the cleaning head can be provided with a movement toward and away from the roller.
  • the movement can be in an axial direction, i.e., can be such as to move the head away beyond an axial end of the roller.
  • the movement of the cleaning head toward or away from the lateral surface of the roller is orthogonal to the rotation axis of the roller, or in any case a movement that has at least one component orthogonal to the axis of the roller.
  • the cleaning head and, together with it, the mechanical cleaning member can be moved with respect to the lateral surface of the roller to be washed, maintaining the contact between mechanical cleaning member and surfaces of the roller.
  • the mechanical cleaning member is provided with a movement inside the cleaning chamber, movement that does not involve the remaining parts of the cleaning head.
  • this movement can be a rotation movement.
  • the mechanical cleaning member can comprise a rotating brush, or preferably two counter-rotating brushes.
  • the movement of the mechanical cleaning member is a reciprocating movement, preferably in a direction parallel to the rotation axis of the roller.
  • the cleaning head can comprise lateral sealing gaskets.
  • These lateral sealing gaskets can have concave edges, with a curvature corresponding to, or slightly lower than that of the roller to be cleaned, so as to embrace the roller if necessary with a slight elastic deformation of the gaskets, to improve the lateral seal.
  • the lateral sealing gaskets can be replaceable as a function of the diameter of the roller to be cleaned.
  • the lateral sealing gaskets can be housed in respective side elements that form lateral walls of the cleaning chamber.
  • the side elements can be adapted to house the lateral sealing gaskets of variable dimensions, as a function of the variable diameter of said roller to be cleaned.
  • the cleaning head comprises an upper sealing blade and a lower sealing blade, adapted to delimit the cleaning chamber above and below.
  • the blades can be biased against the roller to be cleaned to improve the seal.
  • the blades can be elastic, or can be associated with pressure members, such as piston-cylinder actuators, or springs or other elastic biasing members.
  • the mechanical cleaning member can comprise at least one brush.
  • the present invention also relates to a machine comprising a cylindrical roller to be cleaned and a device as defined above and as better described below with reference to examples of embodiment.
  • the invention relates to a method for cleaning a roller, comprising the following steps:
  • Fig. 1 shows an overall view of a printing machine generically indicated with 10, for example destined for printing and decorating a ply web material (not shown), which houses a cleaning device 20 of the invention.
  • the cleaning device 20 is essentially composed of two parts, indicated respectively with 30 (cleaning head) and 40 (movement assembly).
  • the cleaning head 30 acts, in the example illustrated, on an anilox roller 50, which has on the surface a coating made of a hard material, for example a ceramic material, engraved with small cells, which transport the printing liquid, typically an ink. These cells (not shown) can become at least partially clogged with debris consisting of particles of paper and ink. When this occurs the anilox roller 50 becomes unusable and requires a cleaning operation. For this purpose, the cleaning head 30 is brought into close proximity of the anilox roller 50 and subsequently made to translate in a direction parallel to the axis of the roller 50, as better described below.
  • the cleaning head 30 comprises various components, including a mechanical cleaning tool 60, which can be a brush or the like.
  • the cleaning head further comprises a pair of nozzles 70 for spraying a cleaning liquid, upper and lower sealing blades 80 and lateral sealing gaskets 90.
  • the assembly made up of the upper and lower blades 80 and of the sealing gaskets 90 forms, together with the cylindrical surface of the roller 50, a fluid tight cleaning chamber 110.
  • the blades 80 are adjustable and held with pressure against the roller 50 to be cleaned through the use of compression members 100 ( Figs.3B , 3C ) exemplified here in the form of springs, which allow fluid tightness in the upper and lower part of the cleaning chamber 110 also when the there is a variation in the diameter of the roller 50 to be cleaned, as the blades 80 are always in contact and with a certain pressure against the roller 50.
  • the sealing gaskets 90 are supported by respective side elements 120 that, in the same way as the blades 80, can accommodate gaskets 90 of different dimensions, or rather with a concave profile 130 adapted to the variable diameter of the roller 50. This means that, with the same cleaning head 30 and the same side elements 120 it is possible to clean rollers 50 with various diameters, as the cleaning chamber 110 will in any case remain exempt from seepages or leakages of liquid, due to the spring adaptability of the blades 80 and to simple replacement of the sealing gaskets 90.
  • the side elements 120 can cover roughly half of the range indicated above.
  • a first cleaning head 30, and respective side elements 120 to install on the cleaning device 20 for rollers 50 of diameter comprised between around 150 mm and around 220 mm, and a second different (larger) cleaning head 30 with side elements 120 of a size which is larger than previous ones, for rollers 50 with a diameter comprised between around 220 mm and around 300 mm.
  • Fig.6 shows, in an axonometric view, compared with each other, two cleaning heads 30 of different dimensions to cover the whole range of diameters of the roller 50 to be cleaned.
  • a mechanical cleaning member in this case a brush 60
  • the brush 60 is translated with a reciprocating movement in a direction parallel to the axis of the roller 50.
  • the movement of the brush or other mechanical cleaning member 60 is obtained with an actuator, for example a pneumatic motor 61, and the motion is transmitted, for example, through a cam and eccentric or the like, indicated schematically with 62, although it would also be possible to use other systems known in the art.
  • the brush 60 is advantageously formed of two parts 140 ( Fig. 4 ) extending in transverse direction (parallel to the axis of the roller 50), so as to leave a channel 180 between the two parts 140. In this way, a small amount of cleaning liquid coming from the nozzles 70 is maintained in direct contact both with the roller 50 and with the bristles forming the two parts 140.
  • the two parts 140 of the brush 60 advantageously have a dovetail shape (see in particular Figs.2 and 5 ), so as to bring the bristles of the two parts 140 as close as possible to the roller 50 to be cleaned, and to create an obligatory path for the cleaning liquid (maximizing the contact time of the cleaning liquid on the roller and consequently its removal efficiency).
  • each of the two parts 140 of the brush 60 has a surface (for example formed by the tips of the bristles that make up each part 140 of the brush 60) that form an angle ⁇ with a vertical plane.
  • the angle ⁇ can for example be from around 5° to around 20°, preferably from around 10° to around 15°, preferably of around 12°.
  • the aforesaid inclined surfaces of the parts 140 of the brush 60 are inclined in opposite directions, so as to be arranged, in substance, on the two sides of a "V" with opening (180-2 ⁇ ) degrees, so that the two parts 140 of the brush 60 embrace the cylindrical surface of the roller 50 as much as possible.
  • the brush 60 can be provided with bristles of different thickness and material, for example the bristles can have dimensions comprised between 0.05 and 0.5 mm, advantageously between 0.1 and 0.2 mm and be made of filaments of brass, steel, plastic or animal material, or the like.
  • the aforesaid parameters and materials can vary as a function of the shape and of the material of the surfaces to be cleaned, and of the pressure required and expected useful life of the bristles.
  • brushes 60 provided with mixed bristles, i.e. made of different materials, for example harder and softer bristles, which can have various arrangements. For example, clumps or groups of bristles of a first type can be arranged alternated with clumps or groups of bristles of a second type.
  • the brush 60 can be supported so that it also slides in a direction (indicated with Z in Fig. 2 ) toward the roller 50 to be cleaned.
  • This forward movement according to the direction Z has the dual purpose of offsetting any differences in the diameter of the roller 50 to be cleaned, and of adjusting the pressure exerted by the bristles 140 on the roller 50.
  • This latter characteristic can also be exploited to offset partial wear of the bristles, so that the effectiveness of the action of the brush 60 remains more or less constant, extending the useful life of the brush 60.
  • the number 71 ( Fig.2 ) indicates a fixing and adjustment column, along which the cleaning head 30 can translate to move toward the axis of the roller 50.
  • the cleaning head 30 can be supported by an arm (not shown) adjustable in length, so that the seal of the blades 80 and of the sealing gaskets 90 is guaranteed against seepage of cleaning liquid and of any residues removed from the roller 50.
  • the cleaning head 30 (see. Fig. 1 ) is mounted on a movement assembly 40 that controls translation of the cleaning head 30 in a direction parallel to the axis of the roller 50.
  • the movement is indicated by the double arrow X in Fig.1 and is advantageously a two-way movement, so that the cleaning head 30 can translate in the two directions to act on the whole cylindrical surface of the roller 50.
  • the translation movement can be imparted to the head 30 by any known movement system. In the case shown, a rack and pinion system is used, but it would be possible to use other known systems, for example with belt and pulley, with gears, with recirculating ball screws or the like.
  • one or more holes 160 are arranged in the lower part of the cleaning chamber 110, connected to which are pipes 165 ( Fig.3A ) for collecting and recovering the cleaning liquid and any debris detached from the roller 50. Evacuation of the remaining cleaning liquid and of any debris can take place through gravity or vacuum, both induced from the outside, or through slight overpressure that is created in the cleaning chamber 110.
  • the lateral sealing gaskets 90 can be housed in respective seats, obtained in negative in the side elements 120, so that the gaskets 90 with concavity 130 with different diameters (to operate on rollers 50 with different diameters), can in any case be installed on the same side elements 120.
  • the shape of the gaskets 90 is such that they are very easy to replace without the aid of particular tools.
  • the lateral sealing gaskets 90 can be made of different materials, provided the material has sufficient resistance to sliding friction and does not overheat.
  • a particularly suitable material has proven to be "EVA" closed cell expanded polyethylene, with a density comprised between 50 and 120 kg/m 3 .
  • EVA EVA closed cell expanded polyethylene
  • the cleaning head 30 of the device 20 is brought into close proximity of the roller 50 to be cleaned.
  • a slight forward movement of the head 30 in the direction of the roller 50 causes closing of the cleaning chamber 110, delimited laterally by the sealing gaskets 90, which can have the concave front part 130 with a radius of curvature equal to or slightly smaller than the radius of the roller 50.
  • the sealing gaskets 90 can be moved toward the roller 50 with a slight pressure against the cylindrical lateral surface of said roller 50.
  • the cleaning chamber 110 is delimited on top and on the bottom by the blades 80 held with pressure against the roller 50 by the springs 100 or another suitable member, for example another elastic member, a piston-cylinder actuator or other suitable means.
  • the cleaning chamber 110 remains sealingly closed regardless of the direction of rotation of the roller 50.
  • the cylindrical surface of the roller 50 completes the front closing of the cleaning chamber 110, while a wall 31 ( Fig.2 ) of the cleaning head 30 closes it at the rear.
  • the brush 60 After the forward movement and sealing of the cleaning chamber 110, the brush 60, with its bristles 140 coming into contact with the surfaces of the roller 50 to be cleaned through the forward movement of the head 30 toward the roller 50, starts to move inside the cleaning chamber 110 in a direction transverse to the roller, i.e., parallel to the axis thereof, so as to cause the bristles of the brush 60 or other mechanical cleaning member to rub against the surfaces of the roller 50 to be cleaned.
  • the nozzles 70 inject cleaning liquid, which can consist of water, a solution of water and detergent, or another liquid product with a cleansing action.
  • cleaning liquid can consist of water, a solution of water and detergent, or another liquid product with a cleansing action.
  • the combined action of rubbing of the bristles of the brush 60 and of the cleaning liquid ensure that the portion of surfaces of the roller 50 to be cleaned involved and circumscribed by the cleaning chamber 110 is easily cleaned.
  • the particles of paper, ink, or any other processing residues that have deposited in the cells of the roller 50 are easily removed.
  • the used cleaning liquid flows downward, thus drawing the debris toward the hole or holes 160, from where it is removed through the pipe or pipes 165.
  • the supply and removal of the cleaning liquid can take place discontinuously or preferably continuously.
  • the cleaning liquid can be water or any cleaning product, pure or diluted, and can be heated, for example, to a temperature comprised between 25°C and 50°C, preferably between 30 °C and 45°C.
  • the cleaning head 30 can be provided with means to prevent or limit the lateral seepage of cleaning liquid during use.
  • Fig. 7 shows a configuration of cleaning head 30 with double containment chamber.
  • the same numbers indicate the same or equivalent parts to those already described with reference to the preceding figures, which will not be described again.
  • the main difference between the cleaning head 30 of Fig.7 and those illustrated in the preceding figures substantially consists in that a further lateral sealing gasket 91, adjacent to the respective sealing gasket 90 described above, is added laterally on the left and right sides of the cleaning head 30.
  • An empty chamber 92 is formed between the two lateral gaskets 90, 91 of each side of the cleaning head 30.
