Definitions

  • the invention relates to a device for cleaning rollers, in particular paper guide rollers in printing machines, according to the preamble of claim 1.
  • Paper guide rolls of printing machines have a small diameter and are usually not driven directly, but are rotated by the paper web driven by other rolls by friction. After a period of operation, dirt adhering to the peripheral surface of the paper guide rollers, in particular paper fibers, printing ink and dust, has to be removed regularly to avoid contamination of the paper web.
  • the guide rollers of a driven paper web are cleaned by braking the guide rollers so that the paper web moistened with cleaning agent wipes the dirt off the roller by the relative movement between the driven paper web and the slower-rotating paper guide roller.
  • the paper guide roller is rotated by hand and the dirt is washed off by hand. With one method, a lot of paper is required, with the other, there are long machine downtimes.
  • the object of the invention is to provide a device by means of which any type of rollers, in particular paper guide rollers of small diameter, can be cleaned quickly and easily by printing machines.
  • the device 1 according to the invention is particularly suitable for cleaning a non-driven, freely rotatable paper guide roller 2, but also for cleaning other freely rotatable rollers, in particular rollers which have a small diameter of only a few centimeters.
  • All three embodiments of the device 1, as shown in FIGS. 1 and 2 have in common that a drive roller 6 is rotatably mounted in a housing 4 of the device 1, which is driven by a motor 8 which is flanged to the housing 4 or fastened in the housing 4, is driven.
  • a brush roller 10 is rotatably mounted in the housing 4, which has bristles 12 which extend radially outward on its outer peripheral surface and which is connected to the drive roller 6 by a drive connection, for example a gear or a belt drive 14 .
  • a drive connection for example a gear or a belt drive 14 .
  • two support wheels 16, 18 are arranged freely rotating at an axial distance from one another.
  • the support wheels 16, 18 have a smaller diameter than the radial one theoretical cylinder enveloping the outer ends of the bristles 12 so that a particular portion of each bristle 12 extends radially beyond the support wheels 16, 18.
  • the brush roller 10 has the task of brushing dirt off the paper guide roller 2.
  • the support wheels 16, 18 have the task of limiting the penetration depth of the paper guide roller 2 into the brush roller 10 to a predetermined value.
  • the drive roller 6 has the two tasks of driving the paper guide roller 2 by friction and to position itself and the brush roller 10 axially parallel to the paper guide roller 2.
  • the housing 4 is open on a front side 20 facing the paper guide roller 2, as shown in FIG. 1.
  • a liquid application device 24 e.g. a sprayer attached.
  • the scraper 22 extends over the length of the brush roller 10 and extends from the outside inwards between the bristles 12.
  • the liquid application device 24 consists of a spray tube 26, a pump 28 and a storage container 30 for cleaning liquid.
  • a removable collecting container 32 is accommodated in the housing 4.
  • the housing 4 has, on the rear side 34 facing away from the paper guide roller 2, a flap 36 through which the collecting container 32 can be removed and emptied.
  • the device 1 Before switching on the motor 8, the device 1 is first pressed with the open front 20 to the paper guide roller 2 so that the peripheral surface of the drive roller 6, the bristles 12 of the brush roller 10 and the running surfaces of the two support wheels 16, 18 of the brush roller with the engine stopped 10 rest on the peripheral surface of the paper guide roller 2. With the drive roller 6 and the support wheels 16, 18 result in contact with the paper guide roller 2 in the form of a line.
  • the elastic bristles 12 are curved in the contact area with the paper guide roller 2 and pushed to the side, since the bristles 12 protrude radially beyond the support wheels 16, 18.
  • the drive roller 6 and the brush roller 10 partially encompass the paper guide roller 2, as shown in FIG. 1, so that the device 1 on the paper guide roller 2 is aligned axially parallel and fixed transversely to it.
  • the guidance of the device 1 on the paper guide roller 2 is the better, the greater the distance between the two axially parallel device rollers 6, 10.
  • a limit for the distance between the device rollers 6, 10 is, however, given by the diameter of the paper guide roller 2.
  • the motor 8 which drives the drive roller 6 is switched on.
  • the liquid application device 24 which pumps cleaning liquid, for example solvent or water, from the container 30 by means of the pump 28 through the spray tube 26 from an outlet opening 38 of the spray tube 26.
  • the outlet opening 38 of the spray tube 26 is located centrally between the roller ends and is directed from top to bottom into the narrowing gap between the brush roller 10 and the paper guide roller 2, as a result of which the cleaning liquid is sprayed into the contact zone of the two rollers 2, 10 or rinsed or drop by drop is supplied and the peripheral surface of the paper guide roller 2 and the bristles 12 of the brush roller 10 wetted. Since the gap narrowing from top to bottom for the cleaning liquid is an obstacle to drainage, the cleaning liquid is distributed outward from the spray area in the roller axial direction, which results in a uniform distribution on the bristles 12 of the brush roller 10 and the paper guide roller 2.
  • the rotary movements of the drive roller 6 are transmitted to the brush roller 10 with the aid of the drive connection 14.
  • a crossed belt gear 14 is used so that the directions of rotation of the drive roller 6 and the brush roller 10 are in opposite directions. Due to the friction caused by pressing the driven drive roller 6 against the paper guide roller 2 along the line of contact, the rotational movement of the drive roller 6 driven by the motor 8 is transmitted to the paper guide roller 2, whereby the latter rotates in the opposite direction to the drive roller 6.
  • the brush roller 10 rotates due to the reversal of the direction of rotation by the crossed belt gear 14 also in the opposite direction with respect to the pressure roller 6 and thus in the same direction with the paper guide roller 2. Because the rotational movements of the brush roller 10 and the paper guide roller 2 are in the same direction, the circumferential movements of the two rollers 2, 10 are in the region their contact surface directed opposite, which causes a relative movement between the two rollers 2, 10, as shown in Figure 1. The brushing effect is particularly great due to the opposite movement on the contact surface.
  • the bristles 12 of the brush roller 10 are on the flat Contact zone with the paper guide roller 2 against the circumferential direction of movement of the brush roller 10 bent back and spring forward after leaving the contact zone, whereby the cleaning liquid absorbed by the bristles 12 is thrown together with dissolved dirt from the paper guide roller 2 in the circumferential direction of movement of the brush roller 10.
  • the collecting container 32 is arranged in the flight and fall path of the dirt in the housing 4, so that the dirt brushed in the circumferential direction of movement of the brush roller 10 is collected by the collecting container 32.
  • the residual dirt is stripped from the bristles 12 of the brush roller 10 by the scraper 22.
  • the scraper 22 is attached above the collecting container 32, so that the stripped dirt can fall into the collecting container 32, as shown in FIG. After some operating time, the collecting container 32 is removed and emptied through the opened flap 36.
  • the spray tube 26 could also have a plurality of outlet openings 38 distributed over the length of the rollers 2, 6, 10, a part of the spray tube 26 then being arranged parallel to the rollers.
  • the connection between the motor 8 and the pressure roller 6 must be releasable.
  • the pressure roller 6 is connected to the motor 8 by a clutch 40, so that the pressure roller 6 can rotate freely in both directions relative to the motor 8 and is completely decoupled from the latter when the clutch 40 is opened is.
  • the device 1 is first attached to the stationary paper guide roller 2 in the manner described. Then the drive of the paper guide roller 2 is switched on, whereby the paper guide roller 2 rotates and drives the pressure roller 6 by friction, which in turn transmits its movement through the belt transmission 14 to the brush roller 10, so that the brushes the paper roller 2.
  • the device 1 Since the device 1 is generally shorter than the paper roll 2 to be cleaned, the device must be guided along the paper guide roll 2 in order to clean it completely.
  • the three embodiments of the invention differ in the manner in which the device 1 is attached to the paper guide roller 2 and guided along it.
  • two handles 42, 44 are attached to the housing 4, with which the device 1 is held and pressed by physical force onto the peripheral surface of the paper guide roller 2 and guided laterally along it, as can be seen in FIGS. 1 and 2 is.
  • a switch 43 for turning on the motor 8, so that it can be operated with the operator's fingers.
  • the pump 28 is preferably a hand-operated pump, the pump movements of which are generated by the operator on a hand lever 45 which is provided on the other handle 44. If the pump 28 is an electric motor pump, the electric motor is switched with the hand lever 45.
  • the liquid container 30 can be accommodated in this other handle 44.
  • the device 1 of the first embodiment is fastened on a height-adjustable device carrier 46, in the preferred embodiment a trolley with wheels 48, as shown in FIG.
  • the wheels 48 are rotatably mounted on semi-trailing arms 52 which are freely rotatable relative to the carriage 46, so that the semi-trailing arms 52 are automatically aligned with the wheels 48 when the carriage 46 moves in the respective direction of movement.
  • the device 1 with the carriage 46 is pushed by means of the handles 42, 44 to the paper guide roller 2 and the carriage 46 is set to such a height that the drive roller 6 and the brush roller 10 rest against the paper guide roller 2 to be cleaned.
  • the motor 8 is switched on and the device 1 is guided along with the carriage 46 along the paper roll 2 to be cleaned.
  • the device carrier 46 can also be a trolley which can be guided on a wall or on a ceiling of a hall or a building on rails.
  • This rail-guided device carrier 46 can have adjustable and clampable slides in the longitudinal and transverse directions. In operation, the carriage can be adjusted and clamped so that the drive roller 6 and the brush roller 10 bear against the paper guide roller 2 under pretension and the device carrier 46 is supported against this pretensioning force in the rails. In this case, the device carrier 46 exerts the holding and pressing forces on the device.
  • FIG. 4 shows the third embodiment of the invention, in which the device 1 is hung on the paper guide roller 2 and is carried by it.
  • the housing 4 of the device 1 is C-shaped and it encompasses the paper guide roller 2.
  • the two drive rollers 6 and brush roller 10 mounted in the housing 4 lie on the paper guide roller 2 from above and are caused by their own weight and the weight of the entire device 1 Paper guide roller 2 pressed and held on it.
  • a counterweight 54 is attached below the paper guide roller 2 to a bracket 56 of the device 1, which extends from the housing 4 to below the paper guide roller 2.
  • the device 1 is held by the two handles 42, 44 and guided along the paper guide roller 2.
  • the reservoir 30 for the cleaning liquid can be arranged on the bracket 56 and act as a balance weight.
