Pneumatic Motor Vent Opening Prevents Jamming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scrap removal devices suffer from frequent maintenance needs due to wear and tear of springs or piston systems, leading to jamming and operational failures, which disrupt production lines.
Innovation Solution
A pneumatic motor with a vent opening to regulate fluid pressure, minimizing the risk of jamming by allowing continuous fluid discharge, and a dual plugging assembly to ensure smooth actuator movement, enhancing reliability and reducing maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If springs are used to realize one of the two steps of motion, then the device can achieve reciprocating motion, but wear on the springs leads to failures and maintenance interventions
Solution Approach 1:
The patent removes the springs from the system entirely, extracting the problematic component that caused wear and maintenance issues. The reciprocating motion is achieved through a different mechanism that does not rely on elastic elements, thereby eliminating the wear problem while maintaining the desired motion capability.
2Productivity
If material accumulates on the container due to pneumatic motor jamming, then the production line upstream is interfered with, but continuing operation causes faults and failures
Solution Approach 1:
The patent implements preliminary anti-action by designing a mechanism that prevents jamming before it occurs. The cam mechanism and controlled reciprocating motion system ensure smooth operation and prevent material from accumulating on the container in the first place, thereby avoiding interference with upstream production processes and eliminating the need for shutdowns to clear accumulations.

AI summary
A pneumatic motor (1) comprising: an actuator (2) at least partially mobile in an actuation chamber (CA); a first plugging assembly (3) defining a first driving chamber (C1) and a second driving chamber (C2) and comprising a first plug (5) reversibly movable at least between an enabling position and an obstructing position; a second plugging assembly (4) defining a third driving chamber (C3) in fluid communication with the second driving chamber (C2) and an inflow/outflow chamber (CX) in fluid communication with the actuation chamber (CA). In particular, the inflow/outflow chamber (CX) has a first opening (A1) and a second opening (A2) respectively in fluid communication with the inlet opening (I) and the outlet opening (O) of the motor (I). In addition, the second plugging assembly (4) comprises a second plug (7) reversibly movable at least between an inflow position, in which it allows a fluid communication between the inflow/outflow chamber (CX) and the first opening (A1), and an outflow position, in which it allows a fluid communication between the inflow/outflow chamber (CX) and the second opening (A2). In particular, the first plugging assembly (3) and/or the second plugging assembly (4) have a vent opening (S) adapted to promote a continuous discharge of a fluid from the second driving chamber (C2) and/or from the third driving chamber (C3).
