Driving Device Independent Blade Feeder Timing Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing driving devices cannot independently optimize the drive timing of the blade and the feeder, as the pin wheel's rotation inevitably rotates the cam, leading to suboptimal timing for both the feeder and the driver blade.
Innovation Solution
A driving device with a control circuit that manages the electric motor and a supply mechanism allowing the feeder to reciprocate independently, enabling separate control over the blade and feeder drive timing through solenoid actuators and a stopper mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the pin wheel is used to drive both the blade and the feeder through a shared cam mechanism, then the structure is simplified, but the drive timing of the blade and feeder cannot be independently optimized
Solution Approach 1:
The patent divides the drive mechanism into separate components: the pin wheel drives the blade independently, while a separate motor drives the cam to control the feeder. This segmentation allows independent optimization of drive timing for each component, resolving the contradiction between structural simplicity and timing optimization capability.
2Device complexity
If the pin wheel rotation is directly coupled to the cam rotation, then the mechanism is simpler, but the feeder and blade drive timing are coupled and cannot be independently controlled
Solution Approach 1:
The patent decouples the drive mechanisms by using separate motors: one motor rotates the pin wheel for blade control, while another motor rotates the cam for feeder control. This independent drive system allows flexible and independent adjustment of drive timing for both components without mechanical coupling constraints.
Solution Approach 2:
The patent introduces dynamic control through independently controllable motors that can adjust rotation speed and timing. The first motor controls pin wheel rotation speed to adjust blade drive timing, while the second motor controls cam rotation to adjust feeder drive timing, enabling dynamic optimization of operational parameters.

AI summary
Realized is a driving device capable of controlling driving timing of a blade and driving timing of a feeder independently. The driving device of the present invention has a housing having an injection path, a blade hitting a nail supplied to the injection path, an electric motor, a controller controlling drive of the electric motor, a magazine accommodating connected nails, and a supply, mechanism sequentially supplying the connected nails, which are accommodated in the magazine, to the injection path. The supply mechanism has a reciprocable feeder backward and forward, an energizing member energizing the feeder forward, and a stopper holding a position of the backward moved feeder against energization of the energizing member. Then, holding the position of the feeder by the stopper is released based on control of the controller.
