Detection of 1D-codes with picket-fence or ladder arrangement with guided container reading

A conveyor line with two parallel conveyors should be designed as compactly as possible. Various containers with 1D codes are to run in picket-fence or ladder arrangement and be reliably detected. The sensor should have the exact function range necessary for solving the application. Extended functions are not desired by the customer due to budgetary reasons.

Through its compact design, its lateral cable outlet and dovetail, the BCL 200i bar code reader can also be mounted in constrained spaces between the conveyor lines. It reliably detects the 1D-codes, independent of whether they are printed on the label with picket-fence or ladder arrangement. With performance tailored to this application, the BCL 200i offers an efficient price/performance ratio.

Detection of 1D-codes in picket-fence arrangement with guided tray identification

Various trays marked with 1D-codes in a picket-fence arrangement run on a conveyor line. The 1D-codes are to be reliably detected with a bar code reader. The device must be equipped with integrated interfaces and worldwide sensor diagnosis should be possible.

The BCL 200i bar code reader reliably detects 1D-codes in a picket-fence arrangement. The device features integrated Ethernet TCP/IP, Ethernet/IP and PROFINET interfaces. The web-based configuration tool enables remote diagnostics from anywhere in the world.

Diversion: Detecting damaged bar codes using code reconstruction technology

The BCL 200i features a so-called code reconstruction technology. This means that even damaged or soiled bar codes or bar codes with a small bar height can be read without problem. This results in significantly higher system availability with fewer no-reads.


Optimized for guided container and tray identification

With performance tailored to this application, the BCL 200i offers an optimum price/performance ratio.

Compact design for constrained spaces between the conveyor lines

Through the compact design as well as its lateral cable outlet and dovetail, the BCL 200i bar code reader can also be mounted in constrained spaces between the conveyor lines. As a result, it is possible to save space already during the design of the conveyor line.

Activation of the bar code reader without additional sensor systems

With autoReflAct (automatic Reflector Activation), the bar code reader is activated without additional sensor systems. This is achieved by directing the scanner with reduced scanning beam towards a reflector mounted behind the conveyor path. As long as the scanner is targeted at the reflector, the reading gate remains closed. If, however, the reflector is blocked by an object such as a container with a bar code label, the scanner activates the read procedure, and the label on the container is read. When the path from the scanner to the reflector has cleared, the read procedure has completed and the scanning beam is reduced and again directed onto the reflector.

Bar code reading even with a large angle of rotation

The proven code reconstruction technology (CRT) enables bar code readers of the BCL 200i series to read bar codes with a small bar height, as well as bar codes with a damaged or soiled print image. With the aid of the CRT decoder, bar codes can also be read without problem in other demanding situations, such as with a large tilt angle (twist angle).

Frequently asked questions about the BCL 200i bar code reader

With webConfig, just a few minutes are needed for commissioning.

Products with webConfig do not need separate software.

The BCL 200i has a 1-port interface; several code readers can be connected to a switch.

With PROFINET, the entire configuration is stored in the control and is mirrored onto the device when exchanging. The PROFINET station name is conveyed via the "neighborhood detection" function.

The BCL 200i/300i series can be combined.

Thanks to the lateral dovetail mounting and cable outlet, the BCL 200i is optimized for constrained spaces.

With the "webConfig" web-based configuration tool, the BCL 200i can be accessed remotely without the use of an additional external program. As a result, simple and remote diagnosis is possible from anywhere in the world.

Short downtimes, since the parameter set is immediately available following a device exchange. Proven configuration via GSDML file in the control, identical to the BCL 348i.

Yes, standard cables can be used: two M12 connectors (PWR/IO and HOST) with fixed connection cable. This results in fast commissioning and cost savings through reuse of the cables.

Through the integrated "Automatic Reflector Activation (AutoReflAct)" function, the bar code reader can also be activated with a reflector. This eliminates the need for additional sensors.

BCL 300i bar code reader

The all-rounder with a variety of equipment features

In production and logistics, many processes are controlled by the identification of goods and materials through the use of bar codes. The area of application of our readers is correspondingly broad – from compact bar code readers for tight installation spaces on the conveyor line to high-speed scanners for industrial applications. The identification of bar codes is among our core competencies. Select from a variety of designs and and performance levels with the right line, raster or oscillating-mirror scanners. Scanning rates of up to 1,000 scans/s, compact installation dimensions, robust housings and, alternatively, integrated heating for use in deep-freeze areas meet the individual requirements of your application. Our BCL 300i bar code readers provide absolute reliability and maximum system availability.

Container reading with bar codes in ladder arrangement

Requirement: In an intralogistics center, containers with bar code labels run in ladder arrangement. Because the containers extend to the edge of the conveyor line, the bar code must be read from a short distance.

Solution: The BCL 300i bar code readers in the line scanner model can also reliably read the bar codes from a very short distance (zero distance).

Tray reading with bar codes in picket fence arrangement

Requirement: Running on a conveyor belt are various cartons all of which are on trays with bar codes in picket fence arrangement. All of the bar codes are to be reliably detected.

Solution: The BCL 300i bar code readers in the raster scanner model can reliably read all of the bar codes in picket fence arrangement.

Code reading on objects of various height

Requirement: If objects of various height are transported on a conveyor line, it must be guaranteed that the 1D-codes are read independent of their position

Solution: The BCL 300i 1D-code readers are available in models with oscillating mirror that can read moving objects at different heights.

Code reading in constrained spaces

Requirement: If 1D-code readers are used in applications with small installation depth, a device is needed that can also reliably read bar codes from very short distances.

Solution: The BCL 300i 1D-bar code readers are also available as raster scanners with deflecting mirror for zero distance reading. This allows them to reliably read the bar codes even with constrained spaces between conveyor lines. Thanks to the integrated code reconstruction technology, the devices can even read damaged codes reliably.
