Solution Overview

Problem

Existing feed devices for slicing machines fail to ensure consistent and reproducible cutting results, especially with varying slice thicknesses and diameters, leading to sagging or wrinkling of slices due to long distances between the cutting device and transport chain frame.

Innovation Solution

A feed device with a driven feed chain frame that synchronizes its chain movements with the transport chain frame, allowing slices to be directly transferred and maintained flat, using stripper rollers and a counter-bearing device for secure transfer, and an adjustable stop plate for automatic thickness adjustment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If a long distance is provided between the cutting device and transport chain frame, then the slicing machine can accommodate larger diameter cutting knives, but the slices sag or wrinkle during transport

Engineering Contradiction:
Improvedistance between cutting device and transport chain frameVSAvoidflatness of slices
Core Design Contradiction:
Length of moving objectVSManufacturing precision

Solution Approach 1:

A feed chain frame is introduced as an intermediary device between the cutting device and the transport chain frame. This feed chain frame with its own set of chain tips picks up slices directly from the cutting area and transfers them to the transport chain frame, effectively mediating the transport over longer distances without allowing slices to sag or wrinkle.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The transport function is segmented into two separate chain frame systems: the feed chain frame responsible for picking up and initial transport of slices from the cutting device, and the transport chain frame responsible for conveying slices to the depositing device. This segmentation allows each system to be optimized for its specific function and reduces the distance slices must travel unsupported.

Inventive Principle:
Principle #1Segmentation

2Reliability

If the chain movements of feed chain frame and transport chain frame are not synchronized, then the mechanism is simpler, but slices become misaligned or damaged during transfer

Engineering Contradiction:
Improvealignment and transfer accuracy of slicesVSAvoidsynchronization mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

A synchronization mechanism is implemented that monitors and coordinates the movements of the feed chain frame and transport chain frame. This feedback system ensures that the chain tips of both frames are positioned correctly relative to each other during the transfer process, preventing misalignment and damage to slices while maintaining reliable transfer accuracy.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If no height adjustment is provided for varying slice thicknesses, then the device structure is simpler, but thin slices sag or fold during transport

Engineering Contradiction:
Improveaccommodation of different slice thicknessesVSAvoidheight adjustment mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The feed chain frame is designed with adjustable height capability that can be dynamically modified to accommodate different slice thicknesses. This dynamic adjustment allows the system to adapt to varying production requirements while maintaining proper support for slices during transport, preventing thin slices from sagging or folding.

Inventive Principle:
Principle #15Dynamics

AI summary

The device (10) has a supply chain frame (12) relatively arranged towards a transport chain frame (11). A product to be cut slice conveyed towards the transport chain frame is transported from the supply frame into a region between the supply and transport chain frames during transport process. The product to be cut is pierced from chain points of the transport chain frame and is transported into a storage device. Movement of chains (3) of the transport chain frame is synchronized with chains (5) of the supply chain frame.
