Stack Holding Apparatus Preventing Sheet Edge Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stack holding apparatuses damage the peripheral edges of sheet members during stacking due to contact with guide members.
Innovation Solution
A stack holding apparatus with a stacking platform, a pressing mechanism, clamp rods, clamp arms, slide mechanisms, and tilt mechanisms that allow the clamp arms to open and close without rubbing against the sheet members' edges, ensuring the edges are not damaged during clamping and unclamping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If guide members are used to support side surfaces of the stack, then the stack can be held during stacking, but the peripheral edge parts of the sheet members are damaged due to contact with the guide members
Solution Approach 1:
The harmful contact function is extracted from the support function. Instead of using guide members that contact the sheet members, the invention uses a stacking platform that supports the stack from below, separating the holding function from any potential damage-causing contact.
Solution Approach 2:
The stacking platform acts as an intermediary between the stack and the support structure. It provides stable support without direct contact between the guide members and the sheet member edges, eliminating the damage pathway while maintaining holding capability.
2Reliability
If clamp arms are used to clamp sheet members from the upper side, then the sheet members can be securely held, but the clamp arms may rub against the peripheral edge parts causing damage
Solution Approach 1:
The clamping action is applied from the upper side (vertical dimension) rather than from the sides (horizontal dimension). This dimensional change allows secure clamping while avoiding contact with the peripheral edges that would occur with side clamping.
Solution Approach 2:
The clamp arms are designed to approach the sheet members vertically from above, establishing contact in a controlled manner that prevents lateral rubbing. The preliminary positioning ensures that clamping force is applied directly downward without side contact.

AI summary
A stack holding apparatus comprising a stacking platform on which sheet members are stacked, a pressing mechanism constantly pressing the stacking platform toward an upper side in the stacking direction of the sheet members stacked on the stacking platform, a pair of clamp rods arranged in parallel with a front-back direction of the stacking platform so as to face the two left and right sides of the stacking platform, clamp arms fixed to the clamp rods and clamping the sheet members stacked on the stacking platform from an upper side in the stacking direction, slide mechanisms making the clamp rods move parallel to the stacking direction, and tilt mechanisms making the clamp rods tilt so that the clamp arms open to an upper side in the stacking direction while moving away from the stacking platform and further so that the clamp arms approach the stacking platform while closing to the lower side in the stacking direction.
