Object detection on scissor roller conveyors: how sensors avoid jams and downtime

In modern logistics centers, the speed and reliability of conveyor technology is crucial for efficiency and throughput. A common problem: dark cartons, bags or other goods are not always reliably detected, which leads to jams or unnecessary downtime on scissor roller conveyors. This problem can be solved with the right sensors.

The challenge of object acquisition

Flexible scissor roller conveyors have to detect objects of different shapes, sizes and colors. Conventional sensors often reach their limits here, especially with dark cardboard boxes or transparent packaging. Missing or inaccurate detections lead to blocked segments, unnecessary energy consumption and increased wear.

Sensors for roller conveyor systems – precision and efficiency

Built-in sensor between conveyor rollers for monitoring and controlling roller conveyor systems. — The sensor is located directly between the rollers and monitors the conveyor section precisely.

Photoelectronic sensors for roller conveyor systems are suitable for these requirements. They are mounted directly between the rollers and reliably detect parcels – regardless of size, color or surface finish. Reflex sensors with background suppression, such as the OPT1545, offer a large detection range, fast response times and a robust design. In combination with the integrated OPT1546 logic unit, unused segments can be de-energized, saving energy, avoiding jams and reducing maintenance. NFC-based configuration and simple installation also ensure flexible adaptation to different system layouts.

Practical example 1: Parcel registration on flexible scissor roller conveyors

For parcel detection on flexible scissor roller conveyors, sensors are mounted directly between the rollers to detect the exact position of the parcels. The intelligent control of the conveyor sections allows unused segments to be de-energized, which saves energy and reduces wear. This allows the material flow to be optimally controlled while increasing system availability.

Practical example 2: Checking the presence of goods

A package travels along a scissor roller conveyor while the sensor reliably detects it. — Compactly integrated: Mounted between the rollers, the sensor provides precise signals on parcel presence.

Another example is the presence detection of goods. Reflective sensors with background suppression are used here, which reliably detect objects even on difficult surfaces. The sensors supply signals to the integrated logic unit, which ensures that only the segments that are actually occupied are active. This reduces congestion, lowers energy consumption and minimizes maintenance costs. Compactly integrated: Mounted between the rollers, the sensors provide precise signals on parcel presence.
