Definitions

  • Zone screw unit for an ink knife of an ink fountain on a printing press
  • the present invention relates to a zone screw unit for an ink knife of an ink fountain on a printing press, with a pressure bolt which penetrates the threaded bore of a housing of an ink fountain and acts on the ink knife and a device which indicates the position of the zone screw with an actuating lever.
  • the ink supply from the ink fountain to the ductor should not be uniform, but depending on local needs.
  • the ink fountain of the printing presses have corresponding zone screws, the pressure bolts of which penetrate the housing of the ink fountain and print on the ink knife in an adjustable manner.
  • these zone screws are very simple threaded screws that can be screwed in and out for manual adjustment. The problem is that setting the zone screws is time-consuming and that a correspondingly large amount of waste is generated.
  • a preferred exemplary embodiment is shown schematically in the drawing and explained with reference to the following description. It shows :
  • Fig. 1 is a zone screw unit in vertical section, perpendicular to the axis of the ductor and
  • Fig. 2 shows the same zone screw unit in a horizontal tal section parallel to the direction of the duct axis.
  • the invention is based on an existing ink fountain of any printing press. Therefore, these parts are shown purely schematically. The effective design can be much more complex, but it is irrelevant to the invention inasmuch as only a single part has to be adapted to these circumstances.
  • Each printing press is equipped with an ink fountain 2.
  • This comprises a housing 20 with a multiplicity of bores, mostly threaded bores 21, which are provided by zone screws are enforced.
  • the zone screws act directly on an ink knife 22, which bears against a duct 23.
  • the ink present at the duct 23 is intermittently removed by a lifter and transferred to an inking roller of the so-called inking unit.
  • zone bolt unit instead of adapting the ink fountain to a new zone screw unit or even installing a completely new ink fountain, it is proposed to divide the zone bolt unit into two areas in principle, namely a constant area and an adapted type-specific area, namely an adapter element 10.
  • the adapter element 10 essentially consists of a one-piece cylindrical sleeve. This sleeve has a screw
  • the names screw part and plug-in part serve in principle only to differentiate and correspond to the exemplary embodiment shown in the drawing.
  • the design and dimensioning of the screw part 11 is adapted to the existing conditions on an existing housing 20 of an ink fountain 2 to be equipped.
  • the so-called screw part 11 of the adapter 10 is consequently made to order.
  • the plug-in part 12 of the adapter 10 is standardized and always matches the unchangeable remaining part of the zone screw unit 1.
  • the first part of the adapter element 10, which is designed here as a screw part 11, is smaller in diameter than the plug-in part 12 in most cases.
  • the plug-in part 12 is a cylindrically turned part which can be inserted into an adjusting block 13 with a precise fit.
  • the adjusting block 13 preferably has a cuboid shape and has a cylindrical through bore 14.
  • a pressure pin 4 is mounted in this through hole. The pressure pin 4 passes through the adjusting block 13 almost completely and runs centrally through the entire adapter element 10 until it bears against the ink knife 22.
  • the adapter element 10 also has a bore 15 of the same diameter, which completely penetrates the adapter element.
  • the screw part 11 of the adapter element 10 is provided with an external thread 16 which is adapted to the existing internal thread in the bore 21 in the housing 20 of the ink fountain 2.
  • the connection between the adjusting block 13 and the adapter element 10 can take place, as shown here, by means of a fixing screw 17 which is inserted into a circumferential recess 18 on the plug part 12 of the adapter element 10. takes hold.
  • the fixing screw 17 passes through the adjusting block 13 laterally up to an enlarged bore 19.
  • the length and diameter of the enlarged bore 19 are exactly adapted to the plug-in part 12 of the adapter element 10.
  • the adapter element 10 is secured in the axial direction, but can still be rotated, which is useful for assembly and rough adjustment.
  • Another possibility of fixing the plug-in part 12 in the adjusting block 13 is that appropriate annular recesses are made in both parts for a connection that can only be released to a limited extent by means of a circlip 17 ′, whereby axial fixation is also achieved while the two parts can be rotated relative to one another remains granted. This alternative is shown in simplified form in FIG. 1.
  • a bearing bore 40 is provided in the adjusting block 13 perpendicular to the direction of the cylindrical through bore 14 and extends at least into the cylindrical through bore mentioned.
  • this bearing hole 40 which is designed as a blind hole, a swivel body 41 is rotatably mounted in an axially secured manner.
  • the axial securing can take place using conventional means, for example again using a yoke ring.
  • the swivel body 40 has an eccentric, at least part-circle-shaped link track 42 on the end face facing the cylindrical through-bore 14. In this link track 42, a driver attached to the pressure pin 4 engages. mer 43 a. A rotational movement of the swivel body 40 thus leads to an axial displacement of the pressure pin 4.
  • the pressure pin 4 is ground to a flat sliding surface 44 in the contact area.
  • the length of the flat sliding surface 44 corresponds at least to the diameter of the swivel body 40 plus the maximum displacement of the pressure pin 4.
  • the swivel body 40 also protrudes laterally from the adjusting block 13. This allows an actuating lever 51 arranged radially on the swivel body 40 to be provided. Due to its angular position, this lever basically shows the position of the pressure pin 4 relative to the ink knife 22.
  • the display can also be made by a scale 52 on the swivel body 41, whereby its angular position to the control block 13 can be read. However, the setting is considerably more visible if a part 53 having a scale is screwed onto the adjusting block. In the embodiment according to FIG. 1, this part is a cylindrical dome with a corresponding reading scale. If desired, this part 53 can also have the shape of a plate.
  • This display part 53 with scale graduation is exchangeably fastened with a screw 54.
  • the screw 54 engages directly in the cylindrical through bore 14, which is provided with an internal thread at the end.
  • the part 53 carrying the scale can also be designed to be machine-specific.
  • the part 53 carrying the scale can have exactly the width which corresponds to the distance between two adjacent zone screw units. In this case, the part 53 is wider than the adjusting block 13 or wider than the entire width of the remaining zone screw unit 1 without this part 53. In the fully converted state, the parts 53 carrying the scale come to lie close together.
  • the zone screw units When assembling the zone screw units according to the invention, one proceeds by screwing the machine-specifically manufactured adapter element 10 with its screw part approximately into the correct position and then plugging the remaining part of the unit 10 onto the plug part 12 of the adapter element.
  • An advantageously provided tightening area 45 remains free on the adapter element 10. This is used to tighten the adapter element using a tool, for example a fork wrench. Accordingly, the tightening area can be hexagonal or octagonal.
  • the swivel body 41 is set to the minimum position by means of the lever 51 and then the adapter element 10 is screwed in by means of a fork wrench until the pressure of the pressure pin 4 on the ink knife 22 is so great that practically hardly any ink is let through.
  • the actuating lever 51 can consequently the ink delivery to the ductor 23 can be adjusted from minimum to maximum.
  • This setting is easily recognizable, easily adjustable and readable, so that the same setting can be repeated immediately if it is pressed again.
  • the experienced printer will be able to recognize from the print template which setting is at least approximately correct for the correct ink supply.
