Refuse Vehicle Tipper Assembly With Shake-Assisted Container Dumping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current refuse vehicle systems face challenges in efficiently emptying contents from containers into the vehicle's compartment, particularly in ensuring complete dumping and preventing container dislodgment during the pivoting process.
Innovation Solution
A tipper assembly is designed with a base, actuator, transmission, and implement that pivots the container from a base position to a dump position, incorporating a shaker assembly to assist in dumping contents by providing a shake function when in the dump position, ensuring effective emptying and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a tipper assembly is used to pivot the container to a dump position, then the dumping efficiency is improved, but the container may become dislodged during the pivoting process
Solution Approach 1:
The implement is configured to engage with the container before the pivoting action begins, securing it in place. This preliminary engagement prevents dislodgment during the subsequent pivoting motion to the dump position, while still allowing efficient emptying of contents.
Solution Approach 2:
The implement acts as an intermediary between the actuator and the container. It provides a stable interface that securely holds the container during pivoting, preventing dislodgment while enabling the container to be tilted to the dump position for efficient emptying.
2Productivity
If the container is pivoted to a dump position for complete emptying, then the dumping completeness is improved, but the shaking or vibration required may cause container dislodgment
Solution Approach 1:
The implement secures the container to the tipper assembly before the shaking action is applied. This preliminary engagement ensures that when vibration or shaking is used to complete the emptying process, the container remains firmly attached and does not become dislodged.
Solution Approach 2:
The implement serves as a secure intermediary connection between the container and the tipper assembly. It provides sufficient engagement strength to prevent dislodgment during shaking operations while still allowing complete emptying of the container contents through the dump position.
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
The solution enables efficient and complete emptying of refuse vehicle containers, preventing dislodgment and ensuring smooth operation by utilizing a pivotable mechanism with a shake function to facilitate the dumping process.
Implementation Method 1
The electric motor is selectively operable at a natural frequency thereof to provide a shake function to the implement when in the dump position to assist in the dumping of the contents within the container

AI summary
A tipper assembly includes a base, an actuator coupled to the base, a transmission coupled to the actuator, an arm coupled to the transmission, and an implement coupled to the arm. The implement is configured to engage with a container such that operation of the actuator facilitates pivoting the container from a base position to a dump position to dump contents within the container. The transmission is configured to provide a shake function in response to the dump position being reached to assist in the dumping of the contents within the container.
