The patent 1246 480 relates to an inking roller with automatically metered ink supply, which has as an essential feature that on the ink roller with this rotating switch contact in cooperation with an interrupter contact for Control of a valve for the conveyed paint is provided.

In this device, the paint, hereinafter referred to as paint, comes from a storage container by means of a pump or the like through a flexible line to one located on the inking roller Paint distributor. From this the color, preferably from the outside, is applied to the surface of the Inking roller applied evenly by rotating it. The color dosing is done by means of a the switching contact associated with the inking roller, e.g. B. electrically achieved. Actuated by the roller movement the switching contact is a valve which is preferably arranged on the motor part and which automatically doses a Ink feed to the ink roller allows according to their rotational movement.

The device essentially consists of a drive motor that drives a paint pump via a drive shaft drives and the paint located in a paint container through a flexible line Passage valve feeds, which is arranged in accordance with the rotational movement of the inking roller through a Switching contact automatically opened or closed or changed in the passage cross-section that a metered supply of paint can take place.

In an advantageous development, one or more switches for setting the automatic feed, the continuous supply, as well as switching off the ink supply and switching it on or off of the device.

This enables rapid switching from automatic to continuous in an advantageous manner Paint can be supplied, which may be necessary at the start of work and if the paint line is long. The operator only switches to automatic coloring after the color has arrived at the color generator.

The invention will now be explained in more detail using an exemplary embodiment.

The illustration shows an ink roller with automatically metered ink supply and a combination switch.

In order to increase the efficient operation of the device, a should preferably be in accordance with the figure electrical combination switch 24 on the handle 12 with paint supply line 11 or in its Close to be arranged. This combination switch 24 should be in a certain position - in

the drawing exemplifies switching position 0 -

As allow the automatic ink supply to the inking roller 13. When switching to switch position I, the automatic control of the paint supply is interrupted and the gate valve opened. This ensures that at the start of work and for a long time Color supply does not pulse the color, d. H. according to the rotational movement of the inking roller 13 intermittently reaches the color generator 26, but that the color immediately according to the full power of the Ink pump to the ink generator 26 is promoted. After the color has arrived at the color generator 26, the switches Operator back to switch position 0, and now only with the appropriate automatic The ink is released to the ink generator 26 by the rotary movement of the inking roller 13. the Switch position I can also be used to clean the device. The detergent or water can control all channels of the device without hindrance through the automatic control flow through, which significantly shortens the cleaning time. In addition, with switch position I and the paint pump switched to paint mixing, the paint can be sucked back to the paint container. at Switching to switch position II, the automatic paint supply is interrupted and so is the gate valve remains closed. The inking roller 13 can now without any color inflow od any color stripes. Smooth on the painted surface.
