Abstract

A device and a system for a lacquer transfer with a frame, transfer roller with a circumferential lateral wall, a drive unit, a slit nozzle, the slit nozzle at least indirectly connected to the frame, an outside contact surface of the lateral wall including depressions, the transfer roller mounted rotatably about an axis of rotation at the frame, the drive unit configured to drive the transfer roller for the transfer roller to rotate about the axis of rotation. The slit nozzle includes a supply connection, nozzle-cavity, slit-shaped nozzle-channel and at least one limiter, the supply connection coupled to the nozzle-cavity for supplying lacquer to the nozzle-cavity, the nozzle-channel extending from the nozzle-cavity to a muzzle end formed by the slit nozzle at the end of the nozzle-channel for dispensing lacquer, the slit nozzle configured by the limiter to adjust a cross-section in a restriction area of the nozzle-channel.

Dependent claims

A device for a lacquer transfer, the device comprising:

a frame;
a transfer roller mounted rotatably about an axis of rotation at the frame and comprising a circumferential lateral wall which has an outside contact surface that comprises several depressions;
a drive unit mounted to the frame and configured to drive the transfer roller such that the transfer roller rotates about the axis of rotation;
a slit nozzle at least indirectly connected to the frame and comprising a supply connection, a nozzle-cavity, a slit-shaped nozzle-channel, and at least one limiter;
wherein the supply connection is coupled to the nozzle-cavity for supplying lacquer to the nozzle-cavity;
wherein the nozzle-channel extends from the nozzle-cavity to a muzzle end, which is formed by the slit nozzle at an end of the nozzle-channel and configured for dispensing lacquer;
wherein the slit nozzle is configured, by the at least one limiter, to adjust a cross-section in a restriction area of the nozzle-channel;
wherein the muzzle end of the slit nozzle is arranged contactless or in direct contact with the outside contact surface for dispensing lacquer into respective depressions;
and
wherein the transfer roller is configured to roll with the outside contact surface on a work surface of a work piece for transferring the lacquer from the depressions to the work surface of the work piece.

A system for a lacquer transfer, comprising:

a device for a lacquer transfer, the device comprising:
a frame;
a transfer roller mounted rotatably about an axis of rotation at the frame and comprising a circumferential lateral wall which has an outside contact surface that comprises several depressions;
a drive unit mounted to the frame and configured to drive the transfer roller such that the transfer roller rotates about the axis of rotation;
a slit nozzle at least indirectly connected to the frame and comprising a supply connection, a nozzle-cavity, a slit-shaped nozzle-channel, and at least one limiter;
and
an actuator unit configured to displace the at least one limiter;
wherein the supply connection is coupled to the nozzle-cavity for supplying lacquer to the nozzle-cavity;
wherein the nozzle-channel extends from the nozzle-cavity to a muzzle end, which is formed by the slit nozzle at an end of the nozzle-channel and configured for dispensing lacquer;
wherein the slit nozzle is configured, by the at least one limiter, to adjust a cross-section in a restriction area of the nozzle-channel;
wherein the muzzle end of the slit nozzle is arranged contactless or in direct contact with the outside contact surface for dispensing lacquer into respective depressions;
and
wherein the transfer roller is configured to roll with the outside contact surface on a work surface of a work piece for transferring the lacquer from the depressions to the work surface of the work piece;
a sensor configured to detect a thickness of the lacquer;
and
a control unit;
wherein the sensor is connected to the control unit to transmit a sensor signal to the control unit, which sensor signal represents detected thickness of the lacquer;
wherein the control unit is connected to the actuator unit of the device, such that the actuator unit is controllable via the control;
and
wherein the control unit is configured to control the actuator unit of the device based on the detected thickness of the lacquer.
