Embodiment Construction

[0056] exist Figures 1 to 3 The device 1 shown in is used for printing labels 2, for example by means of thermal direct printing. The label 2 is, for example, a self-adhesive label 2 which is arranged in a detachable manner on a carrier strip (not shown) which is supported as a rolling stock so that it can be unrolled on a printing device or Press 1.

[0057] The printing device 1 has a thermal head 3 with a heating strip 4 , wherein the heating strip 4 has a plurality of heating resistors (points) 29 via which the corresponding label 2 is guided past the heating strip 4 Produces printed images of specified print quality on the upper side.

[0058] The thermal head 3 together with the thermal strip 4 is elastically connected to the thermal head carrier 8, here for example via a curved spring 26 configured as a leaf spring and / or a helical spring 27 configured as a helical compression spring (here for the sake of comparison). These two springs are shown for good understandi...

Abstract

The invention relates to a device (1) for printing labels (2) by means of thermal printing, with: a thermal head (3) with a thermal strip (4); a counter-pressure element with a counter-pressure element (6) Carrier (5) in which an introduction gap (7) is formed between the thermal strip (4) and the counter-pressure element (6) through which the respective label (2) to be printed can be guided. gap, wherein the thermal head (3) is movably fastened to a thermal head carrier (8) and wherein the thermal strip (4) is pressed with a preset pressing force against the counter-pressure element (6). In order to reduce operating costs, the invention proposes that the counter-pressure element (6) is movable relative to the introduction gap (7). Furthermore, the invention relates to a method for printing a label (2) using a device (1) as previously defined.

Description

technical field [0001] The invention relates to a device for printing labels by means of thermal printing, with: a thermal head with a thermal strip; a counterpressure element carrier with a counterpressure element, wherein between said thermal strip and said counterpressure Insertion gaps are formed between the elements, through which the respective label to be printed can be guided, wherein the thermal head is movably fastened to the thermal head carrier, and wherein the thermal strip is arranged in a predetermined A set pressing force is pressed against the counterpressure element (during printing operation and / or if the counterpressure element is in the working position). Furthermore, the invention relates to a method for printing labels using such a device. Background technique [0002] Thermal printing is a technique in which a heat-sensitive medium is changed in color, in particular darkened, by point-by-point heat action at the sites of heat action. The point-by-po...
