Binding Machine Object-Driven Power Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional binding machines have complex configurations due to the need for long linkages and drive shafts to transmit power from a motor to the bending and winding devices, making them costly and difficult to manufacture.
Innovation Solution
A binding machine design that uses a movable member pushed by the object to be bound to transmit power to a winding member, eliminating the need for long linkages and drive shafts, and incorporates an elastic deforming part to return the movable member and winding member to their initial positions, allowing for automatic preparation for the next binding operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If power is transmitted from the motor to the bending and winding device using long linkages and drive shafts, then the binding machine can perform the winding function, but the machine configuration becomes complicated and manufacturing cost increases
Solution Approach 1:
The patent extracts the power transmission function from the conventional motor-driven linkage system. Instead of using long linkages and drive shafts to transmit power from a motor, the invention utilizes the pushing force from the object itself during its movement along the movement passage to directly drive the movable member and winding member. This eliminates the need for complex power transmission components while maintaining the winding function.
Solution Approach 2:
The object to be bound serves a dual function: it is both the workpiece and the power source. As the object moves along the movement passage, its own pushing force drives the movable member, which in turn rotates the winding member to wind the binding material. This self-service approach eliminates external power transmission mechanisms and simplifies the overall machine configuration.
2Device complexity
If the binding machine uses a simplified configuration without long linkages and drive shafts, then manufacturing cost is reduced, but power transmission to the winding member becomes challenging
Solution Approach 1:
The patent replaces the conventional motor-driven mechanical power transmission system with a direct mechanical push system. The pushing force from the object during its movement along the movement passage directly drives the movable member, which through a simple connection mechanism rotates the winding member. This substitution eliminates complex mechanical power transmission components while effectively transmitting the necessary power for winding.

Function Achieved in This Case
The simplified configuration reduces manufacturing costs and automates the binding process, ensuring efficient winding and twisting of the binding material without the need for complex power transmission components.
Implementation Method 1
an elastic deforming part configured to return the movable member to the premovement position, and return the winding member to a prerotation position before the winding member rotates to wind the binding material, by a restoring force

AI summary
A binding machine includes a feeding device configured to feed a binding material, a movement passage through which an object to be bound to be moved to a binding executing position passes, a movable member configured to be moved from a premovement position where at least a part thereof is disposed in the movement passage, by being pushed by the to-be-bound object when the to-be-bound object moves toward the binding executing position, a winding member configured to wind the binding material fed to a given position by the feeding device around the to-be-bound object, by rotating while being transmitted power of the movable member moved from the premovement position, and a twisting device configured to twist the binding material wound around the to-be-bound object by the winding member.
