Filling Device Opening Flap Deceleration Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Filling devices face challenges in reducing filling time while maintaining mechanical load on the device, as the opening flap's high-speed movement can lead to product adherence and incomplete filling, and existing solutions either increase mechanical stress or fail to efficiently manage the filling process.
Innovation Solution
Implementing a drive system with a deceleration device that applies an additional deceleration force to the opening flap, allowing for a faster opening speed and reduced mechanical load, using a switching element to control the delay and potentially a throttle element to manage kinetic energy, thereby optimizing the movement of the opening flap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the opening flap moves at high speed to shorten filling time, then productivity increases, but mechanical stress on the filling device increases
Solution Approach 1:
The patent applies a deceleration device that dynamically adjusts the opening flap's movement speed during operation. The device allows the flap to accelerate quickly to reach the open position (improving productivity) but automatically decelerates before closing to reduce mechanical stress. This dynamic speed control resolves the contradiction between high-speed operation and stress reduction.
2Productivity
If the opening flap opens quickly to improve filling speed, then productivity increases, but product adherence to the flap occurs causing incomplete filling
Solution Approach 1:
The patent implements a periodic motion pattern for the opening flap through the deceleration device. The flap follows a controlled cycle: rapid acceleration to open position, brief pause at the open position to allow complete product discharge, then controlled deceleration during closing. This periodic action with intentional pause ensures complete filling while maintaining high overall filling speed.
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
This solution significantly shortens filling time while reducing mechanical loads on the device, ensuring complete filling and improving product scale accuracy by controlling the opening and closing speeds of the opening flap.
Implementation Method 1
By incorporating a delay mechanism, it is possible to apply an additional deceleration force to the movement of the opening flap, thereby slowing it down.
Implementation Method 2
When the discharge flap opens and is in its open position, where the discharge opening has its largest surface area, the product falls into the bag located below the discharge hopper due to gravity.

AI summary
The invention describes a filling device having a dispensing container for filling upwardly open packaging containers and having at least one opening flap for opening and closing an outlet opening for the product, wherein the opening flap is movable along a path between a closed position and an open position by means of a drive. At least one delay device is provided, by means of which the movement of the opening flap over a portion of the path can be delayed.
