Definitions

  • the invention relates to a painting machine in which the sheet-like to sheet-shaped workpieces are moved between a painting cylinder with a jacket made of rubber or another elastic material and a hard impression cylinder, the change in its peripheral speed caused by swelling or regrinding of the painting cylinder can be compensated for by a speed controller is and an adjusting device is provided for the pressure between the painting cylinder and the impression cylinder.
  • Such machines are used, for example, in the manufacture of beverage cans, glass lids or crown caps, where the printing is preceded by an internal coating and an external coating and a protective coating follows.
  • There are special requirements placed on the paint so that it can be used for later punching and deep drawing does not burst.
  • previous painting machines poured paint over the workpieces
  • modern painting machines aim to use paint as economically as possible.
  • painting cylinders with precisely positioned cutouts are often used for recess painting.
  • painting cylinders for full painting have the advantage that they can be reground many times and used for a correspondingly longer time.
  • the change in the peripheral speed of the coating cylinder caused by the reduction in diameter must then be compensated for.
  • a need for compensation for the peripheral speed of the painting cylinder exists to a lesser extent also due to changing swelling in the jacket of the painting cylinder.
  • the precise setting of the pressure between the coating cylinder and the impression cylinder is a prerequisite for achieving an extremely thin and at the same time extremely uniform coating application.
  • a machine of the type mentioned at the beginning is already known from the market due to its own manufacture.
  • the painting cylinder for full painting is driven by a compressed air-operated slip clutch, which enables sensitive regulation of the peripheral speed during the run.
  • This regulation requires operator participation.
  • An electrical control device is installed for the recess painting, which monitors the rigidly coupled cylinder setting. Including uncoupling for setup purposes, a total of three operating states can be set with a switch lever.
  • the adjustment of the coating cylinder and the coating feed roller, the switching on and off of all the rollers, their parallel positioning and the metering of the coating application are central on the operating side the machine summarized using spindles provided with a handwheel.
  • the coating cylinder and the coating feed roller can be fixed to the machine frame without play. However, this does not preclude locally uneven contact pressures, including possible operating errors, across the surface line of the painting cylinder with the high level of safety that has now been desired.
  • the invention has for its object to reliably avoid irregularities in the contact pressures of the painting cylinder with a simple means in a painting machine of the type mentioned in order to realize an extremely thin and therefore particularly economical paint application, and one for the change in its peripheral speed caused by swelling or regrinding of the painting cylinder to create automatic compensation.
  • the two end bearings of the painting cylinder or the impression cylinder are each arranged in a pivotally mounted on the machine frame side part, for pivoting each side part, a motor spindle articulated with one end to the machine frame and with its other end to the side part , the axial pressures applied to the two motor spindles can be detected by a pressure sensor and adjusted to a preselectable constant value by a pressure controller connected to the pressure sensor, and the swivel position of one of the two sub-side parts detected by a displacement sensor is used as a control variable for the speed controller.
  • the manual is therefore reduced on the painting machine Operation for setting the pressure on the mutual preselection of a setpoint.
  • the actual setting is then carried out fully automatically and at a higher speed. Any trend towards a deviating actual value is counteracted immediately during operation.
  • the motor spindles on the two sides of the machine are independent of one another, this ensures that the contact pressure between the coating cylinder and the impression cylinder is the same on both sides.
  • the motor spindles allow a very sensitive pressure setting and preclude ringing compared to a hydraulic or pneumatic drive. In addition to a gain in quality and safety, there is a reduction in operating effort and a space saving due to the elimination of spindles provided with a handwheel.
  • the pair of sub-side parts 10 differ primarily in their shape and in the location of their pivot bearing 12 located on the machine frame 11. Between the motor spindle 13 engaging the sub-side part 10 and the pivot bearing 12, with its end bearing, either the counter-pressure cylinder 14 or the painting cylinder 15 arranged.
  • the pivot bearing 16 of each of the two end bearing supports 17 of the paint supply roller 18 is located either on the stationary machine frame 11 or on the pivotable lower part 10.
  • the two motor spindles 13 are a special component of the adjusting device 19 for the pressure between the coating cylinder 15 having a rubber jacket 20 and the hard counter-pressure cylinder 14 and the two motor spindles 21 are also a special component of the adjusting device 22 for the pressing between the coating cylinder 15 and the coating feed roller 18 of the coating unit 23.
  • the entire coating unit 23 is attached to the two pivotable bearing supports 17 of the coating feed roller 18, which, in addition to the coating unit 23, also simplifies the setting device for the pressing pressures exerted on the coating cylinder 15 of the coating machine and simplifies maintenance of the coating machine.
  • a particularly compact and functionally reliable design of the coating unit 23 results from the fact that in the coating unit 23 the coating feed roller 18 and a further coating roller 24 pressed against it are used to limit a coating reservoir 25. They are preferably in the opposite direction and in the region of the lacquer reservoir 25 in the downward direction driven rotating.
  • a paint scraper 26 directed with its doctor blade against the paint supply roller 18 and a paint scraper 27 with its doctor blade against the paint roller 24 are immersed in a horizontal orientation.
  • a common holding device is provided in such a way that they can be pivoted away from the paint feed roller 18 and the paint roller 24 by means of a support arm 29 having pivot arms 28 and can be pivoted back down and the pivot arms 28 on one to the paint feed roller 18 and the further coating roller 24 axially parallel shaft 30 are mounted for longitudinal displacement.
  • the two pivotable bearing supports 17 of the paint supply roller 18 and the two motor spindles 21 articulated on the machine frame 11 or side part 10 and on the other side on the bearing support 17 are except for the pressure between the painting cylinder 15 and the paint feed roller 18 are set up to expose the painting cylinder 15.
  • the motor spindles 21 have an increased adjustment stroke
  • the bearing supports 17 have a more elongated shape
  • the pivot bearings 16 have a greater distance from the common contact zone of the coating cylinder 15 and the coating feed roller 18.
  • the axial pressures applied to the two motor spindles 13 can be detected by a pressure sensor 31 each and can be adjusted to a preselectable constant value by a pressure regulator 32 connected to the pressure sensor 31. So that the actual setting of the pressure between the painting cylinder 15 and the impression cylinder takes place 14 fully automatically and a changing swelling in the jacket 20 of the painting cylinder 15 and regrinding of the painting cylinder 15 is taken into account.
  • the two motor spindles 13 or the two motor spindles 21 have an additional function. Even with a particularly large diameter range of the coating cylinder 15, which, in addition to changing swelling in the casing 20, permits frequent regrinding, the speed adjustment is thus extremely precise and requires little effort.
  • unused paint fields of the painting cylinder 15 are kept stationary on the jacket 20 of the painting cylinder 15 in order to keep the underside of the workpieces, which follow one another at a distance, clean.
  • the displacement sensor contains 35 an electrical variable resistor of a potentiometer 39 coupled in its rotational movement to the pivoting movement of the side part 10.
  • this also results in an additional function for the side part 10 it detects and the additional construction effort for providing the speed control is kept extremely small .
  • the pressure sensor 31 assigned to the sub-side part 10 is limited to the central region of the workpieces to the pressure regulator 32, the accuracy of the speed adjustment is further increased.
  • the painting machine described With its input-side transport belts 37 and its output-side delivery belts 38, the painting machine described is adapted to the special area of application of one-sided painting of sheet-like sheet metal. However, within the scope of the invention, it can be used quite generally for painting panel-to-sheet workpieces, in particular also those made of cardboard or paper. The improvements in the recess painting are of greater importance, for example, if precise free spaces for adhesive are provided on folding box blanks in the painting.
