Flat Workpiece Stacking Table with Movable Stripping Plane
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for arranging flat workpieces on a collecting table often damage workpieces with large extensions due to insufficient contact and friction, leading to folding or compression when trying to stack them vertically.
Innovation Solution
The collecting table can be adjusted to position workpieces such that only a small part of their surface is on the transport cylinder and the majority on the plane of the stripping means, guiding the next workpiece along a straight path to prevent compression, and holding fingers can be displaced relative to the transport cylinder to maintain a constant distance from the collecting table, reducing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If workpieces with large extension are arranged on the collecting table, then the productivity is improved, but the workpieces are damaged due to insufficient contact and friction
Solution Approach 1:
The collecting table is made movable relative to the transport cylinder, allowing dynamic adjustment of the table position. This enables the system to adapt to different workpiece sizes and extensions, ensuring reliable contact and friction for large workpieces while maintaining productivity
Solution Approach 2:
The position of the collecting table is changed as a variable parameter. By adjusting the table's position relative to the transport cylinder, the system optimizes the contact area and friction between workpieces and the table surface, preventing damage while maintaining arrangement speed
2Device complexity
If the collecting table position is fixed, then the device complexity is reduced, but workpieces with large extension cannot be arranged without damage
Solution Approach 1:
The collecting table is designed with movable positioning capability, allowing it to adjust its position relative to the transport cylinder. This dynamic adjustment enables the system to handle workpieces of varying sizes without increasing overall device complexity significantly
Solution Approach 2:
The device is divided into independently positionable components - the transport cylinder and the collecting table. This segmentation allows the table to be adjusted independently to accommodate different workpiece extensions while maintaining a relatively simple overall structure
3Measurement precision
If holding fingers are used to limit transport path, then workpieces can be arranged in elevated position for counting, but the next workpieces appear offset and require additional space
Solution Approach 1:
The holding fingers are made movable rather than fixed, allowing them to adjust their position dynamically. This enables precise control over workpiece placement and counting while minimizing the space occupied on the collecting table, as the fingers can be repositioned based on the current workpiece being handled
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 adjustment significantly reduces the likelihood of workpiece damage by ensuring full contact between arranged pieces and preventing the next workpiece from being pushed into an already arranged one, allowing for flexible arrangement and handling of various formats without causing harm.
Implementation Method 1
there is sufficiently high static friction between the workpieces, which prevents them from moving against one another
Implementation Method 2
The workpieces maintain their elevated position because the arranged workpieces are pressed against the transport cylinder with a spring force

AI summary
The invention relates to a device (1) for vertically placing flat workpieces (3, 3') on a stacking table (4). In said device (1), the flat workpieces (3, 3') can be conveyed by a conveying cylinder (2) and can be dropped onto the stacking table (4). The leading ends of the flat workpieces (3, 3') are retained on the outer circumference of the conveying cylinder (2) with the aid of holding means and can be released before the workpieces (3, 3') reach the stacking table (4). Stripping means (5) are provided which encompass a plane (7), strip the workpieces (3, 3') released by the holding means from the outer circumference of the conveying cylinder (2), and deflect the workpieces (3, 3') along said plane in the direction of the stacking table (4). Additional holding fingers (10, 11) which allow the flat workpieces (3, 3') to be kept at a distance from the stacking table (4) can be introduced into the conveying path of the flat workpieces (3, 3'). Said holding fingers can be retracted behind the plane of the stripping means when the flat workpieces (3) are to reach the stacking table (4). The inventive stacking table (4) can be displaced relative to the conveying cylinder (2) along the plane (7) of the stripping means (5), in the direction of travel of the flat workpieces (3, 3').
