Definitions

  • the invention relates to a device for coating flat workpieces with flowable materials according to the preamble of claim 1.
  • Such a device is known from DE-PS 34 29 049.
  • a hydraulic cylinder is arranged coaxially to the threaded spindle, so that the threaded spindles act indirectly on the movable bearing blocks of the metering roller via a hydraulic cushion.
  • the setting of the application gap between the metering roller and application roller is therefore carried out in this known device by horizontal displacement of the bearing blocks of the metering roller.
  • the sliding friction inevitably associated with this inevitably influences the control of the application gap between the metering roller and application roller, in particular with low pressure forces, and thus leads to inaccuracies.
  • the object of the invention is therefore to improve the known device so that such friction effects are reduced to a minimum and thus a more precise control of the application gap is possible, especially with low pressure forces.
  • the idea of the invention essentially consists in the fact that the horizontally displaceable bearing block with the integrated pneumatic cylinder is only used for the rough adjustment via the threaded rod insofar as a maximum order gap between the application and metering roller can thereby be set, which limit the displacement path of the bearing block.
  • the actual fine adjustment of the application gap takes place via the pendulum member which is pivotally held in the bearing block and on which the pneumatic cylinder acts and in which the metering roller is mounted.
  • the setting of the dosing stroke of the pneumatic cylinder leading to the application gap in the range of a few millimeters thus leads to a minimal pivoting of the pendulum member and thus to a minimal bearing friction in the axis of rotation XX of the pendulum member, which can be further minimized by using suitable technical means (eg needle bearing). so that the metering stroke can take place practically without friction, in contrast to the much higher static sliding friction effect of the bearing blocks in the previously known device.
  • suitable technical means eg needle bearing
  • a possible sliding friction effect between the end face of the pneumatic piston on the one hand and the associated contact surface of the pendulum member on the other hand is also practically excluded by a needle bearing.
  • the two pneumatic cylinders are controlled by a common proportional pressure control valve, so that a high setting precision and reproducibility of the setting is also possible from the control side, the proportional Pressure control valve accordingly forms the appropriate and advantageous addition to a sensitive control of the order gap from the control side.
  • the device for coating flat workpieces shown in FIG. 1 consists of an application roller 11 and a metering roller 10 lying parallel thereto, which can be pressed linearly against the application roller 11, the width of the nip formed between these two rollers being displaced in the direction of the application roller can be adjusted.
  • the shaft 10A of the metering roller 10 (axis of rotation YY) mounted on both sides in a pendulum member 15, which is enclosed in a fork-like manner by the rear end of a bearing block 14 and is pivotably held there (axis XX), the two axes XX and YY each lying horizontally and parallel to one another and the axis of rotation YY of the metering roller 10 below the axis of rotation XX of the pendulum member 15 comes to rest.
  • the bearing block 14 is fixedly connected on its front side to a threaded rod 12, which can be fixed via a lock nut 12A, 12B to a fixed cross member 13, so that by adjusting the threaded rod 12 by means of the lock nuts 12A, 12B, a digging setting of the bearing block 14 and thus a maximum Order gap between the rollers 10 and 11 can take place. Once this rough adjustment has been made, the bearing block 14 therefore remains stationary.
  • a pneumatic cylinder 16 is integrated in the bearing block 14, the piston rod 16A of which engages in a groove 15A of the pendulum member 15 via a needle bearing 17 approximately at the level of the axis YY of the metering roller 10.
  • the actuation of the pneumatic cylinder 16 and the resulting horizontal displacement (double arrow CC) of the piston rod 16A in the direction of the pendulum member 16 thus exerts a torque on the latter and leads to an adjustment of the application gap between the two rollers 10 and 11.
  • Both pneumatic cylinders 16 are controlled by a common proportional pressure control valve 18, so that a uniform action on the pendulum members 15 is ensured on both sides.
