Cardboard Box Dividing Device Stabilizing Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cardboard box dividing devices face challenges in stabilizing the transport of elongated cardboard boxes, leading to reduced transport speed and efficiency due to instability during transport.
Innovation Solution
A cardboard box dividing device that includes a lower conveyor, an upper conveyor, a pressing device, and a cutting knife, with a lifting/lowering device to move the conveyors and cutting knife in unison, ensuring the cardboard boxes are sandwiched and cut stably, enhancing transport stability and speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If an elongated cardboard box is transported by means of a conveyor, then the cardboard box can be transported from the carton-forming machine to the dividing device, but the posture of the cardboard box becomes unstable during the transport and the transport speed is limited
Solution Approach 1:
The patent combines the upper conveyor and lower conveyor into a coordinated system that works together to sandwich and stabilize the elongated cardboard box during transport. The upper conveyor (123, 124) and lower conveyor (121, 122) operate in unison to provide both support and restraint, preventing posture instability while enabling higher transport speeds.
Solution Approach 2:
The pressing device (125) acts as an intermediary element between the upper and lower conveyors, applying additional pressure to ensure the cardboard box remains stable during transport. This pressing force prevents the box from shifting or rotating, allowing the conveyors to operate at higher speeds without compromising stability.
2Productivity
If the transport speed of the cardboard box is increased, then production efficiency can be improved, but the cardboard box becomes unstable during transport
Solution Approach 1:
The patent merges the functions of multiple conveyors and a pressing device into a unified transport system. This combination provides both the speed necessary for high productivity and the stability control needed to prevent cardboard box instability during rapid transport.
Solution Approach 2:
The system employs dynamic control where the upper and lower conveyors can adjust their speeds and pressures in response to the cardboard box position. This dynamic adjustment maintains stability even at increased transport speeds, thereby improving production efficiency without sacrificing stability.
3Ease of manufacture
If a cutting knife is used to divide the connected cardboard box bodies, then the cardboard boxes can be divided into separate pieces, but the cutting knife may be damaged due to instability of the cardboard box
Solution Approach 1:
The pressing device (125) performs preliminary action by stabilizing and securing the cardboard box before the cutting knife makes contact. This pre-stabilization prevents movement or deformation during cutting, protecting the cutting knife from damage and ensuring reliable cutting operations.
Solution Approach 2:
The pressing device serves as an intermediary that mediates between the unstable cardboard box and the cutting knife. By applying pressure and stabilizing the box immediately before and during cutting, it protects the cutting knife from impact or misalignment that would cause damage.
4Speed
If the cardboard box is not stabilized during transport, then the transport speed must be limited, but production efficiency decreases
Solution Approach 1:
The patent combines multiple conveyors and a pressing device into an integrated system that simultaneously achieves high transport speed and high production efficiency. The coordinated operation of these components ensures stability without limiting speed, thereby maintaining high productivity.
Solution Approach 2:
The system uses dynamic speed adjustment and pressure control to optimize both transport speed and production efficiency. By dynamically adapting the conveyors and pressing device to the specific needs of each cardboard box, the system maintains stability while operating at speeds that maximize production efficiency.
