Food Slicing Machine Weight Giveaway Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Food slicing machines often produce under-weight groups of slices, leading to significant 'give-away' when trying to meet standard weight requirements, causing inefficiency and increased costs due to the need for a make-weight station, which can become overwhelmed and further increase give-away.
Innovation Solution
A food processing system that includes a slicing machine with a control arrangement regulating slice thickness based on real-time feedback from an under-weight signal and end-of-line weighing, adjusting the slice size parameter to minimize give-away by incrementally adjusting the slicing set point, and utilizing an under-weight rate signal to optimize slicing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the slice size parameter is set too low to meet minimum weight requirements, then the make-weight station becomes inundated with under-weight groups and operator workload increases, but the amount of give-away increases substantially
Solution Approach 1:
The control arrangement receives feedback from end-of-line weighing arrangement and under-weight signal generating apparatus, then adjusts the slice size parameter dynamically to minimize give-away while maintaining weight compliance
Solution Approach 2:
The system dynamically changes the slice size parameter based on feedback signals to optimize the balance between meeting weight requirements and minimizing give-away
2Loss of substance
If the slice size parameter is set too high to reduce give-away, then cost efficiency improves, but the make-weight station becomes overwhelmed with under-weight groups
Solution Approach 1:
The control arrangement monitors under-weight group generation rate and adjusts slice size parameter to maintain optimal throughput at the make-weight station
Solution Approach 2:
The slice size parameter is made dynamically adjustable based on real-time feedback, allowing the system to adapt to varying production conditions and maintain make-weight station efficiency
3Adaptability or versatility
If manual monitoring and adjustment of slice size parameter is used, then flexibility to handle product variations is maintained, but system efficiency and consistency decrease
Solution Approach 1:
The automatic feedback control system continuously monitors weight compliance and under-weight group generation, adjusting slice size parameter without manual intervention to maintain both adaptability and high efficiency
Solution Approach 2:
The control arrangement automatically adjusts the slice size parameter based on feedback signals, eliminating the need for manual monitoring and adjustment while maintaining system adaptability

AI summary
A food processing system includes a food slicing machine having a control arrangement for regulating a thickness of slices cut by the machine so that they are cut according to a current value of a slice size parameter. An under-weight signal is generated which is responsive to generation of any under-weight groups of slices by the slicing machine, and an end-of-line weighing device monitors the weight of groups of slices outputted by the system and generates an end-of-line weight signal responsive thereto. The system identifies any under-weight groups of slices so that their weight can be increased by addition of a further slice before being outputted by the system. The control arrangement receives the two signals and determines the value of the slice size parameter having regard to them. The slice size parameter may be adjusted to minimize give-away by the system.
