Sheet Separation Device Using Segmented Claw Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sheet separation devices face challenges in efficiently separating two-ply sheets where only one end is bonded, as they often damage the sheets and require larger, more complex mechanisms to create a sufficient gap for separation.
Innovation Solution
The sheet separation device employs a winding mechanism and claw-shaped separation claws that insert into the gap between the sheets, moving in the width direction to separate the sheets without increasing the device's size, using elastic materials to grip and prevent damage, and guiding the sheets into branched conveyance paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional sheet separation device is used to separate two-ply sheets, then the sheets can be separated, but the device size becomes large and the structure becomes complex
Solution Approach 1:
The separation claw is divided into multiple fingers (first claw finger, second claw finger, third claw finger) that can move independently or in coordination. Each finger targets specific regions of the two-ply sheet (bonding portion and non-bonding portions), allowing precise separation without requiring a large complex device structure.
Solution Approach 2:
The separation mechanism utilizes width direction movement of the separation claw in addition to the conventional conveyance direction. The claw moves in the width direction to insert between sheets and separate them, adding a dimensional aspect that enables effective separation with a more compact device layout.
2Reliability
If a traditional sheet separation device is used to separate two-ply sheets, then the sheets can be separated, but the device size becomes large
Solution Approach 1:
The separation function is segmented into multiple claw fingers that operate in different locations (bonding portion and non-bonding portions) simultaneously. This segmentation allows the device to achieve complete separation without requiring a large overall device size, as each finger handles a specific separation task in its local area.
Solution Approach 2:
By incorporating width direction movement capability to the separation claw, the device can insert the claw between sheets horizontally rather than requiring large vertical or longitudinal space. This dimensional approach enables compact device design while maintaining effective separation capability.
3Productivity
If conventional separation methods are used, then sheets can be separated, but sheet damage occurs
Solution Approach 1:
Different claw fingers are designed with potentially different characteristics to suit their specific separation tasks. The first claw finger handles the bonding portion while the second and third claw fingers handle non-bonding portions. This local differentiation allows each finger to apply appropriate separation force without damaging the sheets, while maintaining overall separation efficiency.
Solution Approach 2:
The separation claw and its fingers are designed to move dynamically in both the conveyance direction and the width direction. This dynamic movement allows the claw to adapt to the sheet's position and tension, inserting smoothly between sheets and separating them without applying excessive or uneven force that could cause damage.

AI summary
A sheet separation device separates a non-bonding portion of a two-ply sheet in which two sheets are overlapped and bonded together at one end of the two-ply sheet. The sheet separation device includes a separator that includes a first separator and a second separator. The first separator is inserted into a gap between the two sheets of the two-ply sheet. The second separator is inserted between the two sheets at said another end of the two-ply sheet that is opposite to the one end of the two-ply sheet and moves in a width direction of the two-ply sheet after the first separator is inserted into the gap and relatively moves from the one end to said another end.
