Contact Sensor for Thin-Walled Transport Container Filling Level Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for filling thin-walled transport containers with notes of value lack a reliable method to determine when the container is completely filled, leading to potential underfilling or premature closure.
Innovation Solution
A device that uses a contact sensor with a rotatable rod and torsion spring to detect the bottom of the transport container, generating a signal only when the container is fully filled, allowing for accurate determination and subsequent closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a thin-walled transport container is used to adapt to the value note stack, then the container can be closeable in a revision-proof manner, but it becomes difficult to determine when the container is completely filled
Solution Approach 1:
A contact sensor acts as an intermediary element between the stuffing unit and the control system. The sensor detects when the value note stack has been completely inserted into the transport container by sensing contact with the container bottom, providing a reliable signal to stop the filling process without compromising the revision-proof closure capability of the thin-walled container.
Solution Approach 2:
The patent replaces complex mechanical filling level detection mechanisms with a simple contact sensor that detects the position of the transport container bottom. This substitution provides reliable filling level detection while maintaining the simplicity and revision-proof characteristics of the thin-walled container system.
2Productivity
If multiple filling steps are used to transport notes into the container, then the container can be filled efficiently, but it becomes difficult to determine when complete filling is achieved
Solution Approach 1:
The contact sensor provides continuous feedback during the multiple filling steps by detecting when the value note stack contacts the container bottom. This feedback mechanism allows the control system to monitor filling progress and determine precise completion after each stuffing operation, maintaining both high productivity through multiple steps and accurate measurement of filling completion.
3Manufacturing precision
If the transport container bottom moves deeper into the receiving unit during filling, then the value note stack is properly positioned, but it becomes difficult to detect when the container is fully filled
Solution Approach 1:
The transport container itself serves as the detection mechanism. As the container bottom moves deeper into the receiving unit during filling, the contact sensor detects the final position of the container bottom, which automatically indicates when the value note stack is fully inserted and positioned correctly. The container's own movement provides the detection signal.
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
Ensures the transport container is reliably and accurately filled before closure, preventing underfilling and ensuring secure, revision-proof sealing.
Implementation Method 1
The receiving unit comprises a contact sensor which, upon contact with the bottom of the transport container, generates a signal
Implementation Method 2
The rod has a first rotary position in which the contact sensor generates no signal and a second rotary position in which the contact sensor generates a signal. When the contact sensor comes into contact with the bottom of the transport container, then the rod rotates from the first rotary position into the second rotary position
Implementation Method 3
a torsion spring is provided which rotates the rod into the first rotary position and against the resistance of which the rod is rotatable into the second rotary position

AI summary
A device (10) for filling a thin-walled transport container (18) made of flexible material with notes of value is described. For this, the device (10) comprises a supply unit (12), a stacking unit (14) and a receiving unit (16) for receiving the thin-walled transport container (18). By means of a stuffing unit (20) the stacked notes of value are moved into the transport container (18) in several successive filling steps. A closing unit (22) closes the thin-walled transport container (18) after the last filling step. The receiving unit (16) comprises a contact sensor (32) which, upon contact with the bottom of the transport container (18), generates a signal that triggers the closing operation or the transport container (18).
