Adjustable Pin Holder for Corrugated Box Gripper
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Adjusting pin type grippers to accommodate different sizes and types of corrugated boxes is time-consuming and prone to slippage, requiring complex reassembly and tool usage to change the number or spacing of pins.
Innovation Solution
An adjustable pin and block system with a pin stabilizer and latch assembly allows for easy movement between operating and non-operating positions, enabling simple adjustment of pin placement and reducing slippage by using a mounting block with passages and a latch assembly for secure pin holder positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the clearance between pins and domes is adjusted by removing and flipping pin blocks, then the spacing of pins can be changed to accommodate different box sizes, but the adjustment process becomes time-consuming and requires tool usage
Solution Approach 1:
The pin block is divided into multiple individual pin holders that can be independently adjusted. Each pin holder can be moved separately to different positions along the mounting block, allowing for flexible pin spacing adjustment without requiring removal or flipping of entire pin blocks. This segmentation enables quick reconfiguration by simply moving individual pin holders to desired positions.
Solution Approach 2:
The pin holders are designed to be movable along the mounting block rather than fixed in predetermined positions. This dynamic configuration allows operators to quickly adjust pin spacing by sliding pin holders to appropriate locations and securing them with set screws, eliminating the time-consuming process of removing and flipping rigid pin blocks.
2Adaptability or versatility
If the number of pins is changed by removing or adding pins, then the gripper can accommodate different box types, but the process requires removing set screws and reassembling components
Solution Approach 1:
Each pin is housed in its own independent pin holder that can be individually removed, added, or repositioned along the mounting block. This segmentation allows operators to easily adjust the number of pins by simply adding or removing individual pin holders without affecting other pins or requiring complex disassembly of the entire gripper assembly.
Solution Approach 2:
The pin holders are designed as universal, interchangeable components that can be used in various positions along the mounting block. Each pin holder is identical and can be relocated to different positions or removed entirely, providing a simple method to adjust both the number and spacing of pins without requiring different specialized components.
3Reliability
If pins are properly inserted and secured, then gripping reliability is maintained, but occasional slippage still occurs during squaring operation
Solution Approach 1:
The pin holders incorporate localized features such as downwardly projecting portions that extend below the mounting block when in the operating position. This local structural enhancement provides additional support and stability to the pins at their insertion point, preventing slippage during the squaring operation by ensuring proper alignment and secure engagement with the corrugated material.
