Linear Motor Alignment Device for Product Row Formation

The patent replaces the mechanical scissor-joint mechanism with a linear motor system that uses electromagnetic fields to drive movement elements. This substitution eliminates complex mechanical linkages while achieving precise, individually controlled movement of alignment elements into gaps between products, thereby reducing device complexity and improving control precision.

The patent changes the control parameter from mechanical linkage geometry to independently controllable motor parameters (voltage, current, pulse width). This allows each movement element to be precisely controlled based on detected gap dimensions, enabling accurate alignment element positioning without the constraints of mechanical mechanism geometry.

The patent designs movement elements that serve multiple functions: they are driven by linear motors to achieve precise positioning, they interact with alignment elements to transfer motion, and they can be individually controlled based on sensor feedback. This multi-functionality allows high alignment precision using a manageable number of components rather than requiring separate dedicated elements for each function.

The sensor unit automatically detects gap dimensions and the control unit autonomously calculates and executes the required movement element positions without manual intervention. This self-service capability reduces the need for complex mechanical adjustment mechanisms and allows precise alignment with simpler, more automated component arrangements.

The patent segments the alignment system into independently controllable units: alignment elements, movement elements, and drive units. Each alignment element can be independently positioned by its associated movement element and linear motor, allowing rapid response to detected gaps without requiring complex coordinated movement of a monolithic structure. This segmentation enables both structural simplicity and high alignment speed.

The patent transitions from stationary to dynamically adjustable alignment elements. The linear motor system enables each alignment element to be actively positioned based on real-time sensor feedback, allowing the system to adapt quickly to varying gap dimensions. This dynamic capability increases alignment speed while maintaining relatively simple structural design through electronic control rather than complex mechanical mechanisms.
