2D-code readers get automation rolling

2D-code readers get automation rolling

11 June 2020

Autarky Automation is one of the leading British developers and manufacturers of automation and conveyor systems. To meet the demanding requirements on an automated tire system, Autarky opted for the latest 2D-code readers from Leuze.

The clients: Autarky and Tyre-Line.

A large part of what Autarky Automation offers is in the area of modular conveyor technology. Here, Autarky offers a wide range of standardized components and accessories. The company thereby contributes to minimizing project planning times and assembly costs. A good example of this is the project for Tyre-Line: Since 1984 the company has been supplying the industry with wheel and tire assemblies – from wheelbarrows to high-performance sports cars.

The task: conveyor system for tire inflation.

For a long time, the tire line at Tyre-Line operated with a simple tire inflation device for standard steel wheel sets. The tires for high-end alloy wheels were inflated manually. Due to increasing growth in orders, a Hofmann tire filling machine was purchased that could handle the complete range of wheel and tire assemblies.

The entire process of storing and retrieving assemblies in the machine was now to be automated. Autarky won the tender to produce a suitable conveyor system and relied on Leuze.

The challenge: tires are round.

Attached to each wheel and tire assembly at Tyre-Line is a slightly adhesive bar code label. It would have been too complicated for Tyre-Line to affix the label at exactly the same location on each assembly. Autarky was therefore charged with developing a solution that could reliably read the bar code. And could do so at any location and at any position over the entire width of the conveyor belt.

"A round object that always looks the same independent of its position is a true challenge for a code reader."

"Proper identification of the assemblies was, however, of decisive importance for the success of the line: the detection of the bar code information needed to tell the Hofmann machine which assembly is approaching and, thus, what air pressure is necessary. That’s why it was so important to select the best possible code reader for this task," explains Brad North, managing director of Autarky. To solve this problem, Autarky turned to the Sensor People at Leuze.

The solution: the DCR 200i from Leuze.

After discussing the application with the Leuze experts, we selected the DCR 200i 2D-code reader," explains North. Leuze, a leading manufacturer of bar code readers with more than 50 years of experience, developed this model especially for fast and omnidirectional reading of 1D- and 2D-codes.

“We mounted three devices on a strap arrangement at the optimum angle and height so that the bar code could be read at any position on the assembly and the conveyor belt."

"In combination with the existing PROFINET communication network, the DCR 200i 2D-code readers from Leuze detect data on the bar code. This is then passed on to the Hofmann machine." Autarky had already used hundreds of standard bar code readers and photoelectric sensors from Leuze. "Our longstanding cooperation with Leuze and the good service made the decision easy for us," says Brad North.

The DCR 200i code reader: fast and reliable.

The DCR 200i camera-based code reader is used to detect and identify bar codes, stacked codes and Data Matrix codes. It is characterized above all by its very fast reading performance. The DCR 200i achieves speeds of up to 6 m/s. It reliably reads 1D- and 2D-codes omnidirectionally. It plays no role here whether they are printed or directly marked, static or moving, inverted or mirrored. This is ensured by the fast imager, the integrated high-performance LED illumination, as well as the high resolution in combination with a very high depth of field.

In the stainless steel housing model with degree of protection IP69K/IP67, the DCR 200i can be cleaned without problem and even used in harsh environments.

The application: simple, intuitive and flexible.

Its compact design, its fastening concept and its simple handling means that the DCR 200i can be integrated easily and quickly in a wide range of different applications. This applies to its mechanical installation as well as its commissioning and configuration.
