Definitions

  • Another gear is mounted for rotation with the inking roller in order to impart rotation to the latter, and a third gear is freely turnably mounted on the shaft of the printing roller and meshes with'the other two gears to transmit motion to the gear which drives the inking roller.
  • the third gear has a diameter corresponding to that of the printing roller.
  • a differential unit is provided, having an input gear train that is driven by the third gear and an output gear train which is coupled with the shaft of the printing roller.
  • the present invention relates generally to printing machines, and more particularly to printing machines having printing rollers and inking rollers.
  • Printing machines of the type outlined above must be capable of being adjusted to different formats. This is done by replacing the printing roller when the format is changed, and usually also the inking roller.
  • the known printing machines use a differential drive which is connected with an adjusting motor.
  • a relatively small central gear drives an input gear of the differential drive, and the output gear of the differential drive is connected with an intermediate gear which serves to change the direction of rotation and which, in turn, cooperates with the so-called format gear mounted on the shaft of the printing roller.
  • the format gear drives the gear which is associated with the inking roller so as to drive the latter.
  • An additional object of the invention is to provide such an improved printing machine which is significantly simpler in its construction than what is known from the art, and which is highly reliable.
  • one feature of the invention recites, in a printing machine having a central roller, a printing roller provided with a shaft and cooperating with the central roller, and an inking roller cooperating with theprinting roller, in a combination which comprises a first gear having a diameter corresponding to that of the central roller and mounted for rotation with the same.
  • a second gear is mounted for rotation with the inking roller to rotate the same.
  • a third gear meshes with the first and second gears to transmit motion to the latter one, this third gear having a diameter corresponding to that of the printing roller and being mounted on and freely turnable about the shaft thereof.
  • a differential unit is provided, having an input gear train driven by the third gear, and an output gear train which is coupled with the shaft of the printing roller.
  • FIG. I is a partly elevational, partly sectioned fragmentary view illustrating those portions of a printing machine which incorporate the present invention.
  • FIG. 2 is a strongly diagrammatic fragmentary end view of the embodiment in FIG. 1.
  • reference numeral 1 identifies a central shaft which is driven in suitable manner and on which there is mounted a central roller 2 which rotates with the shaft 1.
  • a printing roller 4 is mounted on a shaft 3 with which it rotates, cooperates with the central roller 2 in the usual manner.
  • the printing roller 4 receives ink from an inking roller 6 which is mounted for rotation on a shaft 5 and which, in turn, receives ink from an ink pickup roller 7 which dips incrementally into an ink supply 8.
  • a first gear 9 is mounted on the central shaft 1 for rotation with the same; it has a diameter corresponding to the diameter of the central roller 2.
  • the gear is in direct mesh with the teeth of a gear 10 whose diameter corresponds to that of the printing roller 4 and which is turnable about and with reference to the shaft 3, in a manner to be described subsequently.
  • a gear II which is mounted on the shaft 5 so as to rotate the same when it is driven by the gear It). It is evident that for the transmission of motion from the gear 9 to the gear 11, the gear 10 constitutes only an intermediate gear.
  • a differential drive unit 12 is provided which can be operated by a diagrammatically illustrated adjusting motor 16.
  • the unit 12 cooperates with an input gear train, the first gear 13 of which is also turnably mounted on the shaft 3 and has an axially extending hub on which the gear 10 is mounted.
  • the gear 10 can be readily removed from the hub of the gear 13, but while it is in place on the hub it cannot rotate with reference to the gear 13.
  • the latter meshes with the teeth of a gear 14 that is mounted on an input shaft 15 of the differential gear unit 12.
  • the unit 12 also has an output gear train including an output gear 17 which is mounted on the output shaft of the unit 12, which output shaft will be seen to surround a portion of the input shaft 15 with clearance.
  • the gear 17 meshes with the teeth of a gear 18 which also has an axially extending hub and surrounds the shaft 3.
  • the gear 13 is mounted on the hub of the gear 18.
  • the gear 18 is fixedly connected with the shaft 3 to rotate the same.
  • a slip coupling 19 of conventional construction is arranged between the first gear 13 of the input gear train and the last gear 18 of the output gear train. The arrangement is such that there is a transmission ratio of 1:1 between the gears 13 and 18.
  • the gears 10, 13 and 18 When the slip coupling 19 is in engagement, the gears 10, 13 and 18 in effect operate as a single unit so that when the motor 16 is not operated for adjustment purposes, the transmission of motion takes place directly from the gear 9 via the gears 10, 13 and 18 to the shaft 3 of the printing roller 4.
  • the other gears, including those of the differential gear unit 12, just rotate under no-load conditions.
  • the size of the gear 9 and of the gears and 11, and their particular cooperation with the other gears of the input and output gear trains, provide for a particularly precise transmission of power, since as far as the substantial power requirements of the rollers 6 and 7 are concerned, the gear 10 now need only act as an intermediary between the gears 9 and 11 so that, in effect, the power can be transmitted almost directly from the gear 9 to the gear 11, eliminating the flow of power through the differential 12 and the associated input and output gear trains.
  • the latter in turn, can be made relatively weak since they need be able to transmit only approximately of the total power requirement, but at the same time as they are constructed more weakly than was heretofore possible, they can also be produced to much more precise tolerances.
  • the overall effect of the invention is that the novel arrangement can be produced much more economically than anything that was known heretofore, and will operate with considerably greater precision than the prior art, particularly the very fine adjustments which are required for the printing roller 4.
  • slip coupling or clutch 19 assures that in a very simple manner there is in effect a direct power transmission since, when the coupling engages, power is transmitted directly from the gear 9 via the gear 10 to the gear 13, and from there via the differential 12 directly to the terminal gear 18 of the output gear train. From there, in turn, power is transmitted directly to the shaft 3.
  • FIG. 2 shows that the unit 12 and its input and output gear trains are mounted on a carriage 20 in which the printing roller 4 and its shaft 3 are also mounted.
  • this arrangement according to the present invention is superbly simple and permits very ready and speedy exchange of the printing roller 4 and the gear 10 for different ones. Readjustments are almost completely avoided when the exchange of the printing roller 4 and the gear 10 has taken place, because it is now merely necessary to move the carriage 20 until the new printing roller 4 is in engagement with the surface of the roller 2.
  • a combination comprising a first gear having a diameter corresponding to that of said central roller and mounted for rotation with the same; a second gear mounted for rotation with said inking roller to rotate the same; a third gear meshing with said first and second gears to transmit motion to the latter one, said third gear having a diameter corresponding to that of said printing roller and being mounted on and freely turnable about said shaft; and a differential unit having an input gear train driven by said third gear. and an output gear train coupled with said shaft of said printing roller.
