Cold Cuts Cutting Machine Movable Traction Belt
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cold cuts cutting machines face issues with adhesive and frictional forces during the cutting process, leading to inaccuracies in slice position and reduced cutting efficiency due to the interaction between the product bar and the fixed cutting latch.
Innovation Solution
The cold cuts cutting machine employs a pivotable lower traction belt that moves vertically to the product feed direction, minimizing the bearing force on the cutting latch, and can perform both linear and pivoting movements, combined with a movable cutting latch, to reduce friction and adhesive forces, allowing for improved feed and retraction movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the product bar is fed through a fixed cutting latch during cutting, then the cutting structure is simple and stable, but adhesive and frictional forces cause inaccuracies in slice position and reduced cutting efficiency
Solution Approach 1:
The cutting latch is transformed from a fixed structure to a movable one that can shift in the feeding direction. This dynamic adjustment allows the cutting latch to adapt to product position variations caused by adhesive and frictional forces, thereby maintaining slice position accuracy without requiring an overly complex fixed positioning system
Solution Approach 2:
The system performs a retraction movement before the actual cutting operation to counteract the adhesive and frictional forces that would otherwise cause positioning inaccuracies. By preemptively adjusting the product position or cutting latch position, the system eliminates the harmful effects of these forces before cutting begins
2Productivity
If the cutting latch is moved to reduce friction and adhesive forces, then cutting efficiency improves, but the device complexity increases
Solution Approach 1:
The cutting latch is designed with movable components that can dynamically adjust during the cutting cycle. This includes the ability to shift position and modify engagement with the product, reducing friction and adhesive forces while maintaining a relatively simple overall structure through clever mechanical design
Solution Approach 2:
The cutting latch performs periodic retraction and engagement movements in sync with the cutting cycle. This rhythmic motion pattern allows the latch to minimize friction during critical phases while maintaining structural simplicity through predictable, repeating mechanical actions
3Force
If the lower traction belt is made movable to minimize bearing force on the cutting latch, then frictional forces are reduced, but the device complexity increases
Solution Approach 1:
The lower traction belt is transformed from a fixed component to a movable one capable of pivoting and linear movement. This dynamic capability allows the belt to minimize bearing force on the cutting latch during critical phases of operation while maintaining structural efficiency through controlled motion
Solution Approach 2:
The lower traction belt is designed to move not only in the feeding direction but also vertically and through pivoting motion. This multi-dimensional movement capability allows the belt to optimize force distribution and minimize bearing force on the cutting latch from multiple angles, reducing frictional forces effectively

AI summary
A cold cuts cutting machine for cutting food, such as sausage, cheese or meat, for example, into slices, in particular for simultaneously slicing at least two pieces of stick-shaped food by means of a cutting blade. A minimization or a cancellation, respectively, of adhesive and frictional forces or the production of a noncutting pass, respectively, is to be make possible thereby and the supply of the food, which is to be sliced, is to be improved further. The cold cuts cutting machine includes a lower and an upper traction belt, between which the product bar can be guided such that the lower traction belt can carry out a relative movement, which is substantially vertical to the conveying direction of the product bar, with respect to a cutting latch.
