Problems solved by technology

[0005] takes into account inaccuracies in the interaction between the drive system that turns the container and moves it past the camera and the trigger time to capture the image (backlash, synchronous speed changes, etc.), the accuracy of the above method is usually not enough, so that small adjustments to the container must be made later with a separate camera

Embodiment Construction

[0026] according to figure 1 and figure 2 , for example a device 1 which may be a labeling machine, comprises a plurality of rotating supports 3 for containers 5 (in particular bottles), for example a motor-driven turntable with a centering device, and the containers 5 (particularly bottles) by rotating around their main axis relative to their rotational position align. The racks 3 circulate on conveying means 7, such as a conveying carousel.

[0027] The device additionally comprises a fixed camera unit 9 comprising any number of cameras 10 for recording features 5a of the container 5, such as burrs or embossing. To this end, the transport means 7 transports the container 5 through the imaging zone 9a of the camera unit 9 while said support 3 causes a developed view of the peripheral surface 5b of the container 5 to be formed in front of the camera unit 9 . The imaging area 9 a may consist of overlapping imaging areas of the cameras 10 .

Abstract

An apparatus and a method for aligning containers, in particular bottles, in a labeler, the apparatus having rotatable holders for containers to be aligned, and a camera unit for imaging the containers as well as a proximity switch for triggering an imaging function of the camera unit. This allows a precise alignment in combination with a reduced expenditure of time and reduced space requirements.

Description

technical field [0001] The invention relates to a device and a method according to the preambles of claims 1 and 10 . Background technique [0002] When handling bottles on filling lines, especially when applying labels to containers in labeling machines, it is often necessary to align the rotational position of the containers in order to ensure, for example, a sufficiently large gap between the burr and the label. distance and / or correctly position the label relative to the glass embossment. [0003] In this regard, it is known from EP 1 205 388 B2 to record the outer surface of the container over its entire circumference with 4 cameras, to evaluate suitable features in the recorded images and to send instructions to the drive system to move the container Rotate around its longitudinal axis to the desired position. [0004] In devices of this type, the container rotates at a constant angular velocity, which has to be observed as precisely as possible while the features ar...
