Modular Gripper System with Quick-Change Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gripper systems for blow molding machines require lengthy and cumbersome processes for changing handling elements, especially when switching between products with different neck widths, leading to inefficiencies in production.
Innovation Solution
A modular gripper system with a gripper module carrier and a gripper module, featuring a locking device that allows for quick and tool-free connection and disconnection, utilizing a pivotable tension lever and form-fitting holding partners for secure attachment, enabling rapid changeovers without play and minimizing handling time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a one-piece construction of the gripper-like holding element is used, then the structural simplicity is improved, but the changeover time for different products increases
Solution Approach 1:
The gripper system is divided into separate modular components: a gripper module and a carrier. The gripper module can be quickly detached and replaced on the carrier when different products with different neck widths are being manufactured, enabling rapid changeover without replacing the entire gripper assembly.
2Reliability
If a locking device is added for secure connection, then the connection reliability is improved, but the device complexity increases
Solution Approach 1:
The locking device is designed to be actuated manually by the operator without requiring external tools or complex control systems. The tension lever can be pivoted by hand to engage or disengage the locking mechanism, making the system self-servicing and simple to operate.
3Ease of operation
If a tension lever is used for actuating the locking device, then the ease of operation is improved, but the force required increases
Solution Approach 1:
The tension lever is designed to be pivotable between different positions (locked and unlocked) through manual actuation. The lever's geometry and connection points are designed to provide mechanical advantage, allowing an operator to easily pivot the lever with minimal force while achieving reliable locking and unlocking of the gripper module.
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
Facilitates rapid and secure changeovers of gripper modules, reducing production downtime and allowing for efficient handling of various container neck widths, with the locking device providing a secure, tension-proof connection that can be operated manually without tools.
Implementation Method 1
the locking device comprises a tension lever being pivotable into the locking position and the release position for actuating the locking device
Implementation Method 2
the locking device provides a connection between the gripper module and the gripper module carrier without play

AI summary
A gripper system includes a gripper module carrier and a gripper module for holding containers or container preforms, the gripper module having a gripper base and two gripper arms with gripping elements for at least partially gripping around a holding region of containers or container preforms, the gripper arms being mounted on the gripper base such that they can pivot relative to one another, the gripper module being releasably connected to the gripper module carrier, wherein the gripper system further includes a locking device for locking the gripper module to the gripper module carrier, and wherein the locking device is movable into a locking position for locking the gripper module to the gripper module carrier.
