Dough-portioning Apparatus Tool-free Rotation-prevention Bar
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dough-portioning apparatuses are difficult to maintain and clean, especially in large-volume portioning chambers, due to complex tool-based installation of rotation-prevention bars.
Innovation Solution
A multi-row dough-portioning apparatus with a rotation-prevention bar that can be easily installed and removed without tools, featuring a locking unit with a spring bolt and a design allowing perpendicular removal, enabling tool-free installation and maintenance, and a pivoting portioning cylinder for efficient dough portioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rotation-prevention bar is installed using tool-based methods, then the installation is secure and reliable, but the maintenance and cleaning process becomes complex and time-consuming
Solution Approach 1:
The rotation-prevention bar is designed with a self-retaining feature where the bar itself maintains its position through its geometric shape and interaction with the chamber housing, eliminating the need for additional tool-based fastening mechanisms. This allows the bar to be easily installed and removed by hand while maintaining secure positioning during operation.
Solution Approach 2:
The rotation-prevention bar is designed as a separate, removable component that can be independently installed and removed from the chamber housing. This segmentation allows the bar to be easily detached for maintenance and cleaning operations without requiring disassembly of the entire apparatus or specialized tools.
2Ease of operation
If the chamber housing is designed with a projecting section, then the rotation-prevention bar can be easily removed perpendicular to the displacement direction, but the overall device complexity increases
Solution Approach 1:
The chamber housing includes a projecting section that extends in a direction perpendicular to the displacement direction of the measuring piston. This additional dimensional feature provides a clear removal path for the rotation-prevention bar, allowing it to be easily extracted without interfering with other components. The projecting section creates a dedicated access pathway that simplifies maintenance operations.

AI summary
A multi-row dough-portioning apparatus has a chamber housing having a number of portioning chambers for predetermining a portioned quantity of dough. Measuring pistons can each be displaced in the portioning chambers along a displacement direction between a retracted, measuring position and a pushed-out, ejecting position. A rotation-prevention bar is installed in a releasable manner on a rear wall of the chamber housing and interacts with a circumferential recess in the measuring pistons in order to prevent rotation of the same. The chamber housing has a projecting section, which projects beyond the rear housing wall. The rotation-prevention bar is installed on the chamber housing such that, upon release, it can be removed from the chamber housing in a removal direction perpendicular to the displacement direction of the measuring pistons. This results in a dough-portioning apparatus which, even in the case of large-volume portioning chambers, is easy to maintain and clean.
