Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for packaging small-piece products face challenges in maintaining optimal positioning due to product height and dimension variations, leading to suboptimal packaging quality and inefficiencies, particularly when product tolerances change, as they require manual adjustments that disrupt the processing flow.
Innovation Solution
Implementing a system that uses a detection device to record product dimensions and adjust the transfer position dynamically, allowing for adaptive positioning of products along the height, width, and length, using a conveyor track adjustment and downstream device modifications to ensure precise alignment and grip timing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a fixed feeding system is used to convey products, then the system structure is simple and easy to operate, but product positioning precision deteriorates due to variable product dimensions
Solution Approach 1:
The patent applies dynamics by making the conveying element's transfer position adjustable rather than fixed. The conveying element can dynamically adapt its position perpendicular to the conveying direction based on detected product dimensions, allowing it to compensate for variations in product height, width, and length while maintaining precise positioning during transfer.
Solution Approach 2:
The patent implements feedback by using a detection device to measure actual product dimensions and feeding this information back to the control unit. The control unit then adjusts the conveying element's transfer position based on the detected dimensions, creating a closed-loop system that continuously optimizes product positioning precision.
2Manufacturing precision
If manual height adjustment is used to compensate for product tolerances, then product positioning can be optimized, but productivity deteriorates due to process interruptions
Solution Approach 1:
The patent applies self-service by enabling the feeding system to automatically detect and compensate for product dimension variations without human intervention. The detection device continuously monitors product dimensions, and the control unit autonomously adjusts the conveying element's transfer position, allowing the system to self-correct positioning errors while maintaining continuous operation.
Solution Approach 2:
The patent ensures continuity of useful action by implementing continuous detection and adjustment during the product conveying process. The detection device operates throughout the conveying phase, and the control unit makes real-time adjustments to the transfer position without interrupting the conveying motion, maintaining uninterrupted productivity while optimizing positioning.
3Reliability
If the transfer position is fixed for all products, then the system operation is simple, but packaging quality deteriorates due to suboptimal product positioning
Solution Approach 1:
The patent applies parameter changes by dynamically modifying the transfer position parameters (position perpendicular to the conveying direction) based on detected product dimensions. Instead of using a fixed transfer position, the system changes the positional parameters adaptively to match each product's specific dimensions, ensuring optimal packaging quality while maintaining operational simplicity through automated control.

AI summary
The present invention relates to a device and a method for feeding and transferring small products to a downstream device (PD), in particular a packaging device, as well as a system for feeding, transferring, and processing, in particular packaging, small products. To improve packaging quality with varying product dimensions (tolerances), the products are conveyed, according to the invention, on a conveyor belt (FB) to a transfer position where the products are transferred to the downstream device (PD). A dimension of each product perpendicular to the conveyor belt (FB) is detected by a sensing device (HS), and the transfer position of the product is adjusted by an adjustment device based on the detected dimension.
