Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional food dough cutting apparatuses face inaccuracies in measuring and cutting small food dough due to dusting flour adherence on conveyors, and existing rounding devices are complex and expensive, requiring multiple motors for operation.
Innovation Solution
A food dough cutting apparatus that measures the total weight of long and large dough on an upstream conveyor and calculates the weight transferred to a downstream conveyor, allowing precise measurement and cutting, even with adhering dust, using a simplified configuration with a frusto-conical rotating body and magnetic rotation transmission, reducing complexity and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If weight detection is performed on the downstream conveyor, then cutting accuracy is improved, but measurement precision deteriorates due to dusting flour adherence
Solution Approach 1:
Instead of measuring the weight of dough on the downstream conveyor (which is contaminated with dust), the invention measures the weight of dough on the upstream conveyor (which is clean) and calculates the transferred weight by subtracting the remaining weight. This inverted measurement approach eliminates the interference of dusting flour adherence.
Solution Approach 2:
The upstream conveyor acts as an intermediary measurement point. By measuring weight changes on the upstream conveyor, the system indirectly obtains accurate weight information of transferred dough without directly measuring on the contaminated downstream conveyor.
2Ease of operation
If a frusto-conical rotating body with eccentric rotation is used for rounding, then rounding effectiveness is improved, but device complexity increases due to requiring multiple motors
Solution Approach 1:
The invention combines the rotation function and eccentric motion function into a single motor system. The single motor drives the rotating body to rotate while the eccentric structure automatically generates the required eccentric motion, merging what would otherwise require separate motors into one integrated drive system.
Solution Approach 2:
The eccentric rotating body structure allows the system to generate its own eccentric motion through the rotation itself. The eccentric geometry automatically converts rotational motion into the required eccentric orbital motion, making the system self-sufficient and eliminating the need for additional motors or complex control mechanisms.

AI summary
The present invention relates to a food dough cutting apparatus configured to cut a food dough into small food dough having a preset given weight, comprising a weighing conveyor configured to be capable of loading thereon the entire food dough and of measuring a total weight of the loaded food dough, a downstream conveyor configured to support the food dough transferred from the weighing conveyor; a cutting device moving in a vertical direction provided between the weighing conveyor and the downstream conveyor; and a control device configured to control an operation of the cutting device, wherein the control device is configured to continuously control that the total weight of the food dough is updated as a new total weight of the food dough after the small food dough having the preset given weight was cut at the previous cutting operation, thereby repeating the transferring and measuring and cutting operations.
