Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nailing equipment for wooden pallets is inefficient due to the time-consuming process of adjusting nail positions, which limits the overall efficiency of both manual and automatic nailing systems.
Innovation Solution
A nail driving assembly and a loose nail driving device that incorporate a nail guide disk, ratchet, and push rod piston mechanism to enable precise and efficient nail positioning, combined with a crank-slider mechanism for quick adjustment of the nail head position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual positioning of nails is used in handheld nailing machines, then the operator can place nails at desired positions, but labor intensity is high and work efficiency is low
Solution Approach 1:
The patent replaces the manual mechanical positioning system with an automatic control system. The nail guide disk with pre-defined nail slots and the control unit that automatically positions and drives nails eliminate the need for manual operator intervention, thereby maintaining nail positioning capability while dramatically improving work efficiency
Solution Approach 2:
The nail guide disk is designed with pre-defined nail slots at specific positions and angles. The system automatically selects and positions nails in these slots based on the nailing program, enabling the device to serve itself without manual intervention for positioning operations
2Ease of operation
If longitudinal movement of push rack combined with transverse movement of nailing assembly is used to adjust nail positions, then nail positioning is achieved, but the adjustment process is time-consuming and limits overall efficiency
Solution Approach 1:
The patent employs a dynamic nail guide disk that can rotate to different angular positions, allowing rapid switching between different nail patterns. The quick-adjustment mechanism enables the nailing assembly to transition between positions without time-consuming manual adjustments, significantly reducing adjustment time while maintaining full positioning capability
Solution Approach 2:
The nail guide disk is pre-configured with multiple nail slots at predetermined positions and angles. Before nailing operations begin, the system loads nails into these pre-positioned slots, eliminating the need for time-consuming adjustments during the nailing process. The pre-programmed nail patterns are ready for immediate execution
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Significantly improves nailing efficiency by allowing for rapid adjustment of nail head positions and enabling multiple nails to be driven into a foot block in a circular distribution, enhancing the overall productivity of wooden pallet assembly.
Implementation Method 1
A magnet is arranged inside the nail head, located on one side of the through-hole, and uses magnetic force to attract the nail in the adjacent nail slot to the through-hole

AI summary
A loose nail driving device for wooden pallets, comprising a crossbeam, with its lower part allowing semi-finished pallets to pass through, multiple support slides arranged on the crossbeam, which can slide to achieve position adjustment in the transverse direction of the crossbeam. A nailing unit is arranged on the support slides, used for nailing operations at various foot block positions of the semi-finished pallets. The nailing unit includes a frame and a nail driving assembly arranged on the frame. The frame is connected to the support slides through a lifting cylinder. A rotatable large gear and a driving mechanism for driving the large gear are configured on the base frame of the frame. An eccentric hole is machined on the disk surface of the large gear, and the lower end of the nail head of the nail driving assembly is configured within the eccentric hole through a first bearing.
