Fruit Press Tool Mounting With Detachable Axial Stop Carrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fruit presses require significant manual effort and risk of damage during cleaning and maintenance due to the need for separate axial fixing and removal of press rollers and punch heads, which complicates the process and may lead to improper fixation.
Innovation Solution
A common carrier with axial stops is used to securely hold press rollers and punch heads, allowing for easy detachment and reattachment, with resilient loading and rotatable mounting to compensate for misalignments and ensure play-free fixing, facilitated by a fastening nut for secure attachment and monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate axial fixing with locking screws is used for press rollers and punch heads, then secure mounting is achieved, but removal and reattachment requires considerable manual effort and time
Solution Approach 1:
The patent combines multiple axial stopping functions into a single common carrier that holds all axial stops for both press rollers and punch heads. This merging allows simultaneous removal of all pressing tools by detaching one carrier, rather than individually removing each tool as in the prior art with separate locking screws.
Solution Approach 2:
The pressing tools (press rollers and punch heads) are segmented into a modular system where they can be collectively mounted and removed as a group through the common carrier mechanism, while individually maintaining their secure axial fixation through the stopping elements.
2Reliability
If axial locking screws are used to fix pressing tools, then secure fixation is achieved, but risk of damage occurs during removal and reattachment operations
Solution Approach 1:
The common carrier acts as an intermediary mechanism between the operator and the pressing tools. Instead of directly manipulating individual locking screws and tools, the operator manipulates the carrier which mediates the mounting and removal process, reducing direct handling and associated damage risks.
Solution Approach 2:
The design incorporates resiliently mounted axial stops that provide a cushioning effect during the mounting and removal operations. The resilient mounting absorbs shocks and reduces stress concentrations that could cause damage to the pressing tools or shafts during operational changes.
3Reliability
If pressing tools are frequently removed for cleaning, then hygiene is maintained, but productivity is reduced due to repeated assembly and disassembly
Solution Approach 1:
The common carrier merges all axial stopping functions into a single detachable unit, allowing all pressing tools to be removed simultaneously for cleaning. This eliminates the need for repeated individual tool removal and significantly reduces the time lost to cleaning operations while maintaining hygiene standards.
4Manufacturing precision
If resilient loading with spring-loaded stops is used, then play-free fixing is achieved, but device complexity increases
Solution Approach 1:
The patent changes the physical state or properties of the stopping elements by resiliently mounting them, allowing the stops to dynamically adjust their position. This parameter change enables the stops to compensate for manufacturing tolerances and maintain play-free fixing without requiring complex adjustment mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Simplifies the removal and reattachment of pressing tools, reduces the risk of damage, and ensures secure, play-free mounting, facilitating efficient cleaning and maintenance while maintaining functional reliability.
Implementation Method 1
the stops for the press rollers and stamp heads are designed as rubber-elastic pressure transmission bodies, which are placed against the press rollers and stamp heads under elastic prestress
Implementation Method 2
the press rollers and punch heads can be resiliently loaded by the stops in the axial direction, which due to the conical shafts with an axial displacement of the press rollers or punch heads results in the compensation of radial play

AI summary
The press has a frame (1) in which parallel conical shafts are mounted for stamping heads (5) that are driven to and below axial press rollers (4). The heads carry a spherical extrusion die (7) interacting with press recesses (6) of the rollers. A detachable safety unit (12) is provided for the rollers and the heads deferred on the shafts. The safety unit includes a stop part (14) i.e. pressure-transmitting elastic body, rotatably and axially held in a common support (13) for the rollers and heads. The support is detachably connected with the frame in a direction of shafts.
