Camera-based compartment fine positioning
Overview

Camera-based compartment fine positioning
Stacker cranes – from rough to fine positioning
A camera-based positioning system with an evaluation algorithm tailored to the specific application provides a smart solution to compartment fine positioning. Solutions where the camera and evaluation unit are integrated in a compact system are particularly popular with users. These offer straightforward commissioning and operation, without the need for special knowledge.
With the IPS 200i / IPS 400i product family, Leuze offers the smallest camera-based sensor available on the market for the compartment fine positioning of stacker cranes. By means of an additional quality score, it helps to reduce downtimes of stacker cranes, thereby satisfying the call for condition monitoring. Tedious mounting, aligning, and readjusting during operation is no longer required, saving the customer valuable time

Advantages for you
- Flexible use on stacker cranes thanks to its small size
- Eliminates the need for multiple diffuse sensors with only an IPS 200i/400i
- Reduces downtimes through an innovative quality score
- Fast commissioning via the integrated web server or directly at the sensor via configuration codes
- Can be used in different temperature ranges
Highlights

Highlights: IPS 200i / IPS 400i
These camera-based sensors are ideal for the compartment fine positioning of chassis (X-axis) and lifting unit (Y-axis) of the stacker crane in front of single- or double-depth shelf compartments. Any deviations from the target reference position that occur during absolute positioning are thereby detected. The reference position is defined by simple bore holes or reflectors (markers) in the steel profiles (crossbeams or columns) in the shelf compartments. If the marker is located in the working range of the sensor, it delivers the current position relative to the reference position via the integrated interface (Ethernet TCP/IP, EtherNet/IP, PROFINET) or via four digital switching outputs. When the current absolute and reference positions match, the ideal positioning of the stacker crane is reached.
IPS 200i
The IPS 200i is a camera-based sensor for the compartment fine positioning of a stacker crane with single compartment depth. With just one device model, a large working range from 100 to 600 mm can be achieved; the also available, heated version can be used at ambient temperatures as low as -30 °C. Its dimensions are unrivalled with respect to the small size. As a result, installation in constrained spaces poses no problem. Other highlights include the simple operation, the configuration via the integrated web server or directly on the sensor, the four alignment LEDs and the information about the function reserve, which is output as a quality score.

IPS 400i
The IPS 400i is the smallest camera-based sensor on the market for the compartment fine positioning of a stacker crane with double-depth shelves. It helps stacker cranes to quickly and easily find the right rack.
Thanks to its high-performance, ambient-light-independent IR-LED illumination, fault-free use is possible for a working range of up to 2,400 mm. The also available heated version can be used at ambient temperatures as low as -30 °C. Its dimensions are unrivalled with respect to the small size. As a result, installation in constrained spaces poses no problem. Other highlights include the direct configuration on the device, the simple operation, four alignment LEDs and the information about the function reserve, which is output as a quality score. Critical applications with background reflections are solved using customized additional lighting.
