Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blister machines face challenges in reliably separating product breakage from bulk materials, leading to reduced output and increased costs due to rejected packaging and system malfunctions, while existing solutions like camera systems and perforated sheets are expensive and inefficient.
Innovation Solution
A blister machine with a conveying device featuring spaced conveying elements and a cover element forming a gap that allows product breakage to fall through, while products are conveyed without interruption, using adjustable gap widths and alignment devices to ensure reliable separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If camera systems and mechanical rejection devices are used to detect and remove product breakage, then product breakage separation reliability is improved, but device complexity and cost increase significantly
Solution Approach 1:
The invention extracts and removes product breakage from the bulk material stream using a simple mechanical extraction system. A conveyor belt with a gap allows broken products to fall through while intact products continue on the conveyor, achieving separation without complex inspection devices. This applies the extraction principle by physically removing the harmful element (breakage) from the material flow using a straightforward mechanical means.
Solution Approach 2:
The invention replaces expensive, complex camera systems and mechanical rejection devices with a simple, inexpensive gap structure in the conveyor belt. This gap is a basic mechanical feature that can be easily manufactured and maintained, embodying the principle of using cheap, simple structures instead of expensive complex systems to achieve the same functional goal of breakage separation.
2Reliability
If perforated sheets are used to separate product fragments, then separation capability is improved for small fragments, but reliability decreases for larger fragments and certain product shapes
Solution Approach 1:
The invention changes the separation parameter from fixed perforated holes to an adjustable gap width in the conveyor belt. This gap can be modified according to the specific product type, size, and shape requirements, allowing the same basic structure to adapt to different separation needs. The gap width parameter can be optimized for each product type, providing both reliability and adaptability.
Solution Approach 2:
The conveyor belt system with an adjustable gap provides dynamic adaptability to different product types and breakage sizes. Unlike static perforated sheets, the gap width can be changed to accommodate various product dimensions and shapes, making the separation system versatile and reliable across different应用场景.
3Measurement precision
If gap width is reduced to improve breakage separation, then separation precision is improved, but productivity decreases due to potential product loss
Solution Approach 1:
The conveyor belt gap system allows broken products to self-select and fall through the gap based on their size and integrity. Intact products naturally remain on the conveyor belt while broken ones fall through, creating a self-service separation mechanism. This eliminates the need for complex active rejection mechanisms and minimizes product loss, maintaining high productivity while achieving precise separation.

AI summary
A conveying device (2) according to the invention for conveying bulk material comprising products (32) and product fragments (36) thereof in a conveying direction (F) comprises a first conveying element (8), a second conveying element (12) which is connected downstream of the first conveying element (8) such that a gap (18) is formed between the first and the second conveying elements (8, 12), and a cover element (22) which is arranged over the gap (18). The gap (18) has a first width (B1) according to a predefined separation criterion such that the passage of product fragments (36) through the gap (18) is allowed and the passage of products (32) through the gap (18) is prevented.
