Casing Brake Holder Pivoting Mechanism for Sausage Filling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sausage filling devices face challenges in efficiently managing the casing brake's movement to achieve three stable positions and simplify operator handling, particularly in terms of space constraints and complex construction requirements.
Innovation Solution
The casing brake holder enables simultaneous pivoting and withdrawal movements of the casing brake relative to the filling tube axis, incorporating a guide device with a cam mechanism for controlled peeling and pivoting, allowing the casing brake to move in a single plane with reduced effort and improved predictability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the casing brake is moved axially to achieve three stable positions, then the friction control is improved, but the device complexity increases
Solution Approach 1:
The casing brake movement is transformed from purely axial displacement to a combination of radial retraction and axial positioning. The guide device with cam mechanism enables the brake to achieve three stable axial positions (working position, release position, and intermediate position) through controlled radial-axial coupled motion, reducing the complexity of purely axial positioning mechanisms.
Solution Approach 2:
A guide device with cam mechanism is introduced as an intermediary between the drive system and the casing brake. This guide device translates rotational cam motion into the required three-position axial displacement of the casing brake, simplifying the overall control system while maintaining reliable friction control at each position.
2Ease of operation
If the closing device is moved away to create space for casing brake movement, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
Instead of moving the closing device axially to create space, the casing brake is designed to retract radially outward from the filling tube axis. This radial movement in a different dimension creates the necessary clearance without requiring the closing device to be displaced, thereby maintaining closing device simplicity while improving operator access.
Solution Approach 2:
The movement of the casing brake is segmented into two independent phases: radial retraction (peeling movement) and axial positioning. This segmentation allows the brake to clear the closing device path without requiring the closing device itself to move, simplifying the overall system while enabling easy operator intervention.
3Ease of operation
If pneumatic drives are used for positioning the casing brake, then the ease of operation is improved, but achieving three stable positions becomes more difficult
Solution Approach 1:
A cam mechanism is introduced as an intermediary between the pneumatic drive and the casing brake. The cam profile is designed with three distinct valleys corresponding to the three stable positions. The pneumatic drive provides the actuating force, while the cam mechanism ensures precise positioning and stability at each position, combining the advantages of both pneumatic actuation and mechanical positioning.
Solution Approach 2:
The cam mechanism converts continuous pneumatic pressure into periodic motion with three distinct stable positions. As the cam rotates or translates, the casing brake follows the cam profile, naturally settling into stable positions at the cam valleys. This periodic mechanical guidance ensures reliable positioning while maintaining ease of pneumatic control.

AI summary
Disclosed is an apparatus for filling tube-shaped or bag-shaped packaging with pasty material, comprising a charging pipe (1) and a holder for a casing decelerator that is disposed on the charging pipe (1). The pull-off movement is performed using a swiveling and drawing movement when the charging pipe (5) is swiveled away, thus allowing the casing decelerator to hold three stable positions relative to the charging pipe (5) while requiring little space and being easy to remove from the pipe (5) in order to replace a packaging tube.
