Circular Weighing Device Vibration Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing combination weighing devices are unsuitable for weighing long and thin, soft articles like strips of jerky meat and cheese codfish, as they tend to bend or break during the weighing process and are difficult to align and discharge orderly.
Innovation Solution
A combination weighing device featuring a circular arrangement of weighing units, a collection hopper, and an alignment and transport unit with vibrationally aligned collection troughs and shutters to align and transport the articles without bending, and a pusher for efficient discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If articles are vertically received and fall into the guiding cylinder, then the weighing process can be completed, but the articles may bend or break at the time of impact
Solution Approach 1:
The patent applies vibration to the collection trough to gently transport soft, long, and thin articles horizontally instead of allowing them to fall vertically. The vibration mechanism (electromagnetic shaker or eccentric shaft) creates oscillating motion that moves articles along the trough bottom without impact, preventing bending or breaking while maintaining productivity.
2Stability of the object's composition
If articles are aligned manually, then the articles can be arranged orderly, but the processing time increases
Solution Approach 1:
The patent employs self-service alignment where the vibrating collection trough automatically orients and aligns articles through its vibration motion. The articles themselves interact with the vibrating surface to achieve proper alignment without external intervention, eliminating manual alignment operations while maintaining orderly arrangement.
Solution Approach 2:
Vibration of the collection trough creates oscillating motion that causes articles to naturally align and orient themselves along the trough bottom. This automatic alignment process occurs during transport, eliminating the need for separate manual alignment steps and reducing processing time.
3Ease of operation
If the collection trough is stationary, then the structure is simple, but the articles cannot be aligned and transported orderly
Solution Approach 1:
The collection trough is equipped with a vibration mechanism (electromagnetic shaker or eccentric shaft) that generates oscillating motion. This vibration enables the trough to transport soft, long, and thin articles horizontally without impact while simultaneously aligning them through the oscillating movement, achieving both alignment and transport functions.
Solution Approach 2:
The collection trough transitions from a static structure to a dynamic one with vibration capability. The vibration mechanism allows the trough to adapt its motion characteristics to gently handle and align soft articles, improving operational ease while adding controlled complexity through the vibration system.

AI summary
A combination weighing device includes a plurality of weighing units arranged in a circular form, a combination scale configured to temporarily retain, in a collection hopper, articles discharged from one or more of the weighing units selected as a result of combinatorial computations and to discharge the articles from the collection hopper, and an alignment and transport unit configured to align and vibrationally transport the articles discharged from the collection hopper.
