[0001] AUTOMATIC LABELING MACHINE AND WORKING METHOD

[0002] TECHNICAL FIELD

[0003] The invention relates to an edge-tracking automatic labeling machine for labeling flexible materials flowing along a line, and to a method of operation.

[0004] PRIOR ART

[0005] In the industry, labeling machines are preferred for the identification and control of materials or products as they move along the line, and for the processing of certain information as a result of the control. Labels are attached to a point on the material automatically or manually. The barcode, text, markings, etc. on the label may be pre-printed or printed online in the line. In conventional labeling machines, the label is fed in rolls, guided by rollers and passed through a scraper. As it passes through the scraper, the label is separated from the strip to which it is adhered and adhered to the desired position or to a fixed location by means of vacuum or roller systems.

[0006] For labels to be affixed to a fixed point, problems arise if there is a change in the width of the material to be labeled. Certain along the line When edge labeling flexible materials that flow at a speed, the material width can vary. If the material width becomes smaller, a stationary labeller cannot apply a label to the material. A rail-driven labeller, on the other hand, can apply the label to the material if it is informed of its destination. These methods are known in the art, For materials with variable widths, it is always insufficient for labeling a fixed distance from the edge.

[0023] DETAILED DESCRIPTION OF THE INVENTION

[0024] The invention is characterized by a labeling machine (1 ), linear rail (2), chassis (3), flexible material (4), sensors (5) consisting of edge tracking sensors

[0025] (5.1 ) and inductive sensors (5.2), scraper (6), plate (7), motor (8), reflector (9) and distance between the edge sensor centers (10).

[0026] The labeling machine (1) is mounted on a linear rail (2) and integrated on a chassis (3).

[0027] The flexible material (4) slides over the plate (7) under the machine and moves along the line. The width of the flexible material (4) varies. The labeling machine (1 ) has the ability to stick the label on the strip flowing over the scraper (6) at the same distance from the edge of the flexible material (4) at all times. This is ensured by the edge tracking sensors (5.1 ) on the labeling machine (1).

[0028] The edge tracking sensors (5.1 ) are photoelectric sensors and are mounted on top of each other with a distance between their centers (10). There is a reflector (9) on the plate (7) opposite the edge tracking sensors (5.1 ). The flexible material (4) passes between the reflector (9) and the edge tracking sensors (5.1 ).

[0029] The labeling machine (1 ) determines the reference position for the movement due to the inductive sensor (5.2) on the chassis (3). When the labeling machine (1 ) starts, the edge of the flexible material (4) to be tracked is detected by the sensor between the centers (10) of the edge tracking sensors

[0030] (5.1 ). One of the edge tracking sensors (5.1 ) sees the flexible material (4), the other sees the reflector (9). If the width of the flexible material (4) increases, both edge tracking sensors (5.1 ) start to see the flexible material (4). If the width of the flexible material 4) decreases, both edge tracking sensors (5.1 ) start to see the reflector (9). According to the signal from the edge tracking sensors (5.1 ), the controller on the machine drives the motor (8) and the labeling machine (1 ) so that the edge of the flexible material (4) remains at the distance between the sensor centers (10) (the distance between them is at least 2 mm). Thus, the label always stays at the same distance from the edge and therefore always sticks at the same distance from the edge.

[0031] The angle on the scraper (6), the channel connection feature at the connection point of the scraper (6) allows the chassis (3) to be compatible with the industrial machines in the field and to approach the flexible material (4) at the desired angle for labeling.
