Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stick pick-up devices for sausage production lines face challenges such as complexity, difficulty in control, and risk of pushing up multiple sticks due to multi-stage lifting mechanisms, leading to inefficiencies and safety concerns.
Innovation Solution
A stick pick-up device with a simple structure featuring a stick stock portion with an inclined receiving surface, a reverse inclined wall, and a push-up portion with an inclined push-up surface that allows sticks to be pushed one by one along the reverse inclined surface, using an actuator and push-up member to guide sticks downstream.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-stage lifting mechanisms are used to feed sticks one by one, then the sticks can be controlled to move downstream, but the device complexity increases and difficulty of control arises
Solution Approach 1:
The stick feeding device is divided into distinct functional segments: a stick stock portion with inclined bottom surface for storage, a reverse inclined wall with specific geometry, and a push-up portion with inclined push-up surface. Each segment performs a specific function in the stick feeding sequence, simplifying the overall control mechanism while maintaining reliable one-by-one feeding.
Solution Approach 2:
Instead of using complex multi-stage lifting mechanisms that push sticks upward through multiple levels, the invention inverts the approach by using a reverse inclined wall that allows sticks to be pushed upward along its surface, then naturally guide them downstream using gravity and the inclined surfaces. This inversion simplifies the mechanical complexity while achieving the same feeding control.
2Productivity
If two stick lifting members are used to push up sticks in two stages, then sticks can be fed one by one, but the risk of pushing up a plurality of sticks increases
Solution Approach 1:
The push-up portion is designed with a specific local geometry where the inclined push-up surface makes contact with only one stick at a time. The contact area and angle are optimized to ensure that the pushing force is concentrated on a single stick, preventing multiple sticks from being pushed up simultaneously while maintaining efficient feeding.
Solution Approach 2:
The invention changes the geometric parameters of the push-up mechanism, specifically the inclination angle of the push-up surface and the dimensions of the reverse inclined wall, to control the stick feeding process. By adjusting these parameters, the device ensures that only one stick can be pushed up at a time, improving reliability while maintaining productivity.
3Reliability
If a gate plate and push-up portion are used to control rod member feeding, then rod members can be fed one by one, but the difficulty of control and device complexity increase
Solution Approach 1:
The stick stock portion is designed with an inclined bottom surface that automatically guides sticks toward the downstream side. The reverse inclined wall and push-up portion work together to create a self-regulating system where the geometry itself controls the one-by-one feeding mechanism, eliminating the need for complex gate plate operations and reducing control difficulty.
