Definitions

  • a dampening device applies moisture to the plate cylinder of a printing press by means of "a dampening roll in engagement with the cylinder/Dampening fluid is supplied to the dampening roll via a transfer chain including a transfer roll in engagement with the dampening roll and driven with the same circumferential speed as the plate cylinder, a moisture-transmitting in- 13 Claims, 5 Drawing Figures BACKGROUND It is essential for satisfactory functioning of dampening devices of the general kind above referred to in which during operation all rolls are in continuous engagement'that a uniform layer of dampening fluid is already supplied to the roll which is the first one in the fluid transfer chain driven at the circumferential speed of the plate cylinder.
  • German patent application does not satisfy the afore pointed out basic requirement.
  • Control of the layer of dampening fluid is effected by a squeezing roll movable into coaction with the fountain roll of the device.
  • Such an arrangement as the sole control step has been found to be insufficient. Additional steps such as a change in the setting of coacting rollers effecting the printing cannot be accurately supervised as to their efficiency.
  • Metering of the moisture is dependent to a large extent on the type of material used for the sleeves covering the rolls and the roughness of this material or in other words, depends strongly on the wettability of the rolls.
  • Another disadvantage of the dampening device according to the German patent application is that the circumferential speed of the fountain roll depends on the quantity of moisture to be dipped out of the fountain basin.
  • the circumferential speed of the fountain roll in practice rather small but the circumferential speed of the transfer roll which is in direct contact with the fountain roll, depends upon the operational speed of the press itself and this is generally very high. Accordingly, the slippage between the fountain roll and the transfer roll is bound to be also high which is very unfavorable for a satisfactory control of the feed of dampening fluid.
  • a more specific object of the invention is to provide a novel and improved dampening device of the general kind above referred to in which the slippage between the fountain roll and the transfer roll can be very accurately regulated and the extent of the slippage is reduced.
  • the regulation of the slippage and the extent thereof affect the flow of dampening fluid to the dampening roller, reduction and accurate regulation of the slippage greatly improve the uniformity of the flow of dampening fluid.
  • the intermediate roll is driven by a gearing which makes it convenient to select the required gear ratio.
  • the gear ratio of the gearing is advantageously variablewhereby the differential between the circumferential speeds of the fountain roll and the intermediate roll is adjustable.
  • the division of the slippage between the transfer roll and the intermediate roll on one hand and between the intermediate roll and the fountain roll on the other hand, can be conveniently selected in accordance with the specific requirements of the printing job to be performed.
  • a motor which drives the fountain roll independent of the main drive for the press.
  • the drive for the fountain roll is derived from the main drive for the press the conditions for controlling the speed of the fountain roll in accordance with the specific requirements of the printing job to be performed are limited.
  • Such limitation is avoided by providing an independent drive for the fountain roll.
  • Such independent drive permits programming for an increased supply of dampening fluid when the press is started or for a reduced supply at high speeds of the press as evaporation is then relatively lower.
  • rotation of the fountain roll may be continued when the press is temporarily stopped.
  • the intermediate roll can be moved into and out of engagement with the transfer roll and also adjusted with respect to its pressure of engagement by means known for the purpose. Such adjustability of the position of the intermediate roll provides a further means for controlling the moisture feed to the dampening roll. Furthermore, elastic rolls can be removed out of engagement with the coacting rolls in the event the press is stopped for a prolonged period of time to avoid the formation of flattened areas on the circumferential wall of elastic rolls.
  • the fountain roll axis at a slant with respect to the intermediate roll axis. This permits adjustment of the gap between the rolls at the mid-portion thereof with respect to the gap at the ends of the rolls; an increase of the gap at the mid-portion of the rolls due to sagging of the rolls can be prevented in this manner.
  • the invention further contemplates the provision of a squeezing roll which is movable into and out of engagement with the fountain roll and can also be adjusted as to its engagement pressure.
  • a squeezing roll coacting with the fountain roll and extending either across the entire length of the fountain roll or only across selected zones thereof, further improves the control capability of the dampening device.
  • a doctor or wiping assembly coacts with the fountain roll.
  • This assembly can be conveniently so arranged that it coacts with the fountain roll at selected zones only.
  • the invention further provides that the dampening roll is positively driven with the circumferential speed of the plate cylinder and, in turn, drives a distributing roll in frictional engagement with it.
  • distributing roll made for example with a copper wall, is particularly advantageous when a dampening roll with a rubber sleeve is used. Any ink reaching the dampening roll is attracted by the copper wall of the distributing wall which thus acts as a cleaning roll.
  • the positive drive of the dampening roll prevents slipping of the roll. Danger of slipping is particularly acute due to the relatively strong braking moment exerted by the distributing roll as this roll is driven by frictional engagement with the circumferential wall of the dampening roll.
  • the structure of the dampening device may be simplified in this connection by positively driving the intermediate roll at the same circumferential speed as the transfer roll.
  • This can be conveniently arranged by providing on the intermediate roll a gear in mesh with a gear secured to the transfer roll.
  • Such an arrangement saves the need for a variable gearing which otherwise must be provided between the fountain roll and the intermediate roll.
  • the resulting assemblage is very simple and sufficient in most cases. It has the further advantage that a considerably more uniform film of water is supplied to the printing plate as with the exception of the fountain roll all rolls are driven with the circumferential speed of the plate cylinder. Hence, the coaction of the rolls tends to make'the film of water highly uniform.
  • FIG. 1 is a elevational side view of a dampening device in which the moisture-transmitting intermediate roll is driven with a circumferential speed different from that of the rotational speed of the fountain roll;
  • FIG. 2 is a plan view of the dampening device of FIG.
  • FIG. 3 is a fragmentary plan view of a modification of the dampening device in which the fountain roll of the dampening device is driven independently of the power drive for the press;
  • FIG. 4 is a plan view of a dampening device in which the intermediate roll is driven with the same circumferential speed as the transfer roll;
  • FIG. 5 is a plan view of a dampening device similar to the device of FIG. 4 but having a drive means for the fountain roll independent of the power drive for the ress.
  • the dampening device as exemplified in FIGS. ,1 and 2 comprises a dampening roll 1 with an elastic but preferably uncovered surface in rolling engagement with the circumferential wall of a plate cylinder 3.
  • This plate cylinder should be visualized as constituting a plate cylinder of an offset rotary printing press which is not shown in detail as it does not constitute part of the invention.
  • Dampening fluid such as water to be applied to plate cylinder 3 is transferred to dampening roll 1 from a pan or basin 4 into which dips a fountain roll 5 with a nonelastic water-wettable surface.
  • the fountain roll transfers moisture picked up by it via an elastic moisturetransmitting intermediate roll 6 and a non-elastic transfer roll 7 to dampening roll 1 which, in turn, applies the moisture to the printing plate on plate cylinder 3.
  • Transfer roll 7 is preferably a distributing roll mounted for axial reciprocation.
  • Each end of the dampening roll is joumalled in one end of a lever 8.
  • the levers are pivotal by suitable means such as a pneumatic cylinder 9 about an axis 10 which is located slightly outside of the rotational axis 11 of transfer roll 7.
  • levers 8 pivoting of levers 8 in clockwise direction throws the dampening roll 1 out of engagement with plate cylinder 3 and transfer roll 7.
  • the dampening roll is joumalled in levers 8 by means of an eccentric bushing 12.
  • This bushing can be turned by means of a handle 13 so that the spatial position of dampening roll 1 within levers 8 and thus also with reference to plate cylinder 3 and transfer roll 7 is adjustable when levers 8 are held stationary.
  • Levers 8 further journal a distributing roll 14 by means of an eccentric bushing 15 so that this roll can be moved into and out of engagement with roll 1 by pivoting a lever 16 mounted on bushing 15.
  • Distributing roll 14 is driven by rolling engagement with the circumferential wall of dampening roll 1. This drive may be utilized in a conventional manner to effect also axial reciprocation of roll 14.
  • Intermediate roll 6 is joumalled by means of levers 18 which are pivotal about an axis 20 by pneumatic cylinders 19 for the purpose of throwing the intermediate roll into and out of engagement with transfer roll 7.
  • the engagement between the two rolls 6 and 7 can be finely adjusted by a suitable setting means such as a finely threaded screw 21.
  • Fountain roll 5 is doubly eccentrically joumalled, namely in an eccentric bushing 22 and also in an eccentric bushing 23.
  • Bushings 22 and 23 can be independently rotated with reference to each other by handles 24 and 25 respectively.
  • the fountain roll 5 may be thrown into and out of engagement with intermediate roll 6.
  • the axis of the fountain roll can be set at a slant with reference to the axis of the intermediate roll.
  • the fountain roll is coacting with a squeezing roll 26 and a doctor blade or wiper 27.
  • Both roll 26 and blade 27 can be moved into and out of coaction with roll 5 by setting means known and suitable for the purpose.
  • roll 26 and blade 27 can be so arranged that they coact either with the entire width of the fountain roll or only with selected zones thereof. Arrangements suitable for such selective coaction are well known in the art.
  • transfer roll 7 is positively driven via an intermediate gear 28 which is in mesh with a gear 29 secured to theshaft of plate cylinder 3 and also with a gear 30 secured to the shaft of transfer roll 7, the shaft of the plate cylinder being driven by the main drive of the press (not shown).
  • Dampening roll 1 is driven by a pair of gears 31 and 32 secured to the shaft of transfer roll 7 and dampening roll 1, respectively.
  • the drive shaft of transfer roll 7 is further coupled to a gearing 33 of conventional design the transmission ratio of which can be varied by an actuating handle 34.
  • Gearing 33 is drivingly coupled to a further gearing 36 with a variable transmission ratio by a suitable transmission means 35 such as a belt drive.
  • a change in the gear ratio of gearing 36 is effected by means of an actuating member 37.
  • the flow of moisture from fountain roll 5 to transfer roll 7 can be accurately adjusted by suitably varying the gear ratio of gearings 33 and 36.
  • the gear ratio of gearing 36 is preferably maintained constant after the optimal setting thereof has been determined. In other words, the fine setting is effected by adjusting gearing 33 only. 7
  • fountain roll 5 is driven independently of the main drive for the press by a speed variable motor 38 via transmission means 35.
  • gearing 33 may be omitted but the positive coupling between fountain roll 5 and intermediate roll 6 by gearing 36 is retained.
  • a gear 40 fixedly secured on the shaft of intermediate roll 6 is in mesh with gear 31 on the shaft of transfer roll 7.
  • the gear ratio between gears 30, 31 and 40 is selected so that rolls 1, 7 and 6 rotate with the same circumferential speed as plate cylinder 3.
  • the circumferential speed of fountain roll 5 can be varied by changing the gear ratio in gearing 33 by means of actuating member 34, the gearing being coupled to roll 5 by transmission 35, or according to FIG. 5 by means of an actuating member 41 of a gearing 43 with a variable gear ratio which couples a motor 42 to the fountain roll.
  • a dampening device for a printing press including a plate cylinder driven by the power drive of the press, said device comprising in combination:
  • first drive means for driving the transfer roll with a circumferential speed equal to the circumferential speed of the plate cylinder
  • second drive means for positively driving said intermediate roll with a circumferential speed different from the circumferential speed of the fountain roll.
  • the dampening device according to claim 1 and comprising setting means for selectively throwing the fountain roll into and out of engagement with the intermediate roll and also for varying the engagement pressure between said rolls.
  • said setting means include means for placing the rotational axis of the fountain roll at an angle with reference to the rotational axis of the intermediate roll.
  • the dampening device comprising a squeezing roll coacting with the circumferential wall of the fountain roll, and setting means for throwing said squeezing roll into and out of engagement with the fountain roll and also for varying the engagement pressure between said rolls.
  • transmission means positively couple said first drive means to the dampening roll for positively driving the latter with a circumferential speed equal to the circumferential speed of the plate cylinder.
  • transmission means positively couple the intermediate roll with the transfer roll for positively driving said rolls at the same circumferential speed.
