Solution Overview
Problem
Strapping machines lack flexibility and precision in positioning straps, often resulting in malfunctions due to predetermined strapping positions that do not adapt to the dimensions or markings on objects, leading to inefficiencies and potential damage.
Innovation Solution
Incorporating a camera-based detection system that identifies object dimensions and markings, allowing the control unit to adjust strapping positions dynamically, and using position detection devices to ensure accurate placement and avoid critical areas such as address fields.

1Productivity
If predetermined strapping positions are used, then the strapping process is simple and fast, but the positioning accuracy and adaptability to different objects deteriorates
Solution Approach 1:
The patent implements dynamic adjustment of strapping positions based on real-time object detection. The control unit receives data from detection devices (cameras, scanners) that scan objects on the conveyor, automatically calculates optimal strap positions considering object dimensions, shape, and sensitive areas, then dynamically adjusts the strapping mechanism to apply straps at these calculated positions rather than fixed predetermined positions.
Solution Approach 2:
The system incorporates detection devices that continuously monitor object properties and provide feedback to the control unit. This feedback loop enables the system to adapt strapping parameters in real-time based on actual object characteristics, ensuring precise strap placement while maintaining efficient processing speeds through automated closed-loop control.
2Device complexity
If fixed strapping positions are used, then the device complexity is low, but the adaptability to different object dimensions and markings deteriorates
Solution Approach 1:
The patent replaces complex mechanical adjustment mechanisms with an automated control system that uses detection devices (optical sensors, cameras) and computational algorithms to determine strapping positions. This substitution of mechanical systems with sensor-based detection and computer control achieves high adaptability to various object dimensions and features while maintaining relatively simple physical hardware architecture.
Solution Approach 2:
The control unit dynamically changes strapping parameters (position, tension, timing) based on detected object characteristics. The system stores multiple strapping parameter sets corresponding to different object types and automatically selects and adjusts the appropriate parameters based on real-time detection, enabling versatile adaptation without requiring complex mechanical reconfiguration.
3Device complexity
If predetermined strapping positions are used, then the control system is simple, but malfunctions occur due to straps placed over critical areas deteriorates
Solution Approach 1:
The detection devices scan and identify critical areas (address fields, labels, sensitive surfaces) on objects before the strapping process begins. The control unit calculates optimal strap positions that avoid these pre-identified critical areas, preventing malfunctions before they occur. This preliminary detection and planning ensures reliable strapping operation while maintaining relatively simple control logic.

AI summary
The development relates to a method, a device, and a system for strapping objects, comprising the following steps: • Transporting an object to a strapping station using at least one conveying device (13, 14), • Forming at least one loop of strapping band around the object using a strapping device, • Connecting the ends of the loop together. The control of the strapping process is to be simplified and made more flexible. For this purpose, it is proposed to use a microcontroller to monitor the movement of the components activated during strapping and the object to be strapped via a control unit (11) and to control it individually for each strapping process in an optimized manner.To avoid strapping certain areas, the following is proposed: • Capturing the optical features of the object using a camera (20); • Evaluating the image from the camera (20) to determine areas that should not be covered by strapping; • Controlling the strapping position so that the strapping position lies outside the areas not to be strapped.
