Nailing Machine Magazine with Notched Access for Jam Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power drive nailing machines face issues with nail clogging in the injection port, requiring cumbersome operations to remove clogged nails, often necessitating separate openable parts or tools to detach and reattach the magazine, which increases weight and cost.
Innovation Solution
The design incorporates a magazine with guide rods and a notched portion on the side walls, allowing for easy removal of clogged nails without the need for openable/closable parts or tools, by exposing the injection port through an opening and notched area, enabling direct access with a punch or similar tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If an openable/closable front plate is formed at the nose portion to expose the injection port, then the clogged nail can be removed, but the device complexity and weight increase
Solution Approach 1:
The magazine is extracted as a separate removable component from the nose portion. By detaching the magazine, the injection port becomes accessible for nail removal without requiring additional openable plates or complex mechanisms at the nose portion.
Solution Approach 2:
The nailing machine is segmented into distinct components: the nose portion and the magazine. This segmentation allows the magazine to be removed independently, providing access to the injection port while keeping the nose portion structure simple and fixed.
2Ease of repair
If the magazine is detached from the nose portion to remove a clogged nail, then the injection port becomes accessible, but the operation time and complexity increase
Solution Approach 1:
The magazine is designed with pre-positioned attaching portions and notched openings that facilitate quick attachment and detachment. The attaching portions are positioned to engage with corresponding features on the nose portion, allowing rapid connection and disconnection without complex tools or procedures.
3Reliability
If attaching portions are formed on the magazine, then the magazine can be securely attached to the nose portion, but the device complexity increases
Solution Approach 1:
Attaching portions are provided only at specific locations on the magazine where connection to the nose portion is required, rather than making the entire magazine complex. The attaching portions include simple features such as notched openings and engagement surfaces that provide secure attachment without overall structural complexity.
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
This solution allows for effortless removal of clogged nails without increasing the machine's weight or cost, eliminating the need for separate parts or tools, simplifying the operation and maintenance process.
Implementation Method 1
driving the piston contained at inside of a cylinder by a pressure of compressed air
Implementation Method 2
a combustion gas drive nailing machine is formed with a combustion chamber at inside of a housing for generating a combustion gas at high pressure by combusting a combustible gas

AI summary
A magazine includes guide portions formed at a pair of side walls to be opposed to each other for introducing to guide a portion of a nail shaft portion, an opening portion formed on a base end side of a nose portion relative to the guide portion of one of the side walls, a first attaching portion formed on a front end side of the nose portion relative to the guide portion of the one side wall, a second attaching portion formed on the base end side of the nose portion relative to the guide portion of the other side wall, and a notched portion formed on the front end side of the nose portion relative to the guide portion of the other side wall.
