Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing edge clamping devices in cloth washing factories face challenges in accurately clamping cloth edges due to variations in cloth size and shape, leading to positional deviations and incorrect clamping, which affects processing accuracy.
Innovation Solution
An edge clamping device with a two-position holding device, edge locating conveyor, and clamping chuck system, equipped with a sensor and position changing mechanism to adjust the holding device, conveyor, or clamping chuck in a crosswise direction to ensure correct clamping of the right-angled triangular part, regardless of cloth size or shape variations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed two-position holding device and clamping chuck system is used, then the device structure is simple, but the clamping position varies when processing cloth of different sizes and shapes
Solution Approach 1:
The patent implements a movable holding device that can shift in the crosswise direction relative to the delivery direction, transforming a static system into a dynamic one. This allows the holding device to adapt its position based on the detected location of the right-angled triangular part, enabling processing of various cloth sizes and shapes while maintaining accurate clamping position
Solution Approach 2:
The patent designs a universal clamping system that can handle multiple types of cloth (bath towels, face towels, pillowcases, etc.) with different sizes and shapes using the same basic device structure. The universality is achieved by combining the movable holding device with a sensor-based detection system that automatically adjusts the clamping position
2Manufacturing precision
If the holding device is made movable to adjust clamping position, then clamping accuracy improves, but device complexity increases
Solution Approach 1:
The patent incorporates a sensor that detects the position of the right-angled triangular part of the cloth and provides feedback to the control system. This feedback mechanism enables automatic adjustment of the holding device's position, ensuring accurate clamping while reducing the need for complex manual adjustment mechanisms
Solution Approach 2:
The patent replaces complex mechanical adjustment mechanisms with a sensor-based detection and control system. The sensor detects the triangular part position, and the system automatically controls the holding device movement, substituting intricate mechanical linkages with a more streamlined sensor-actuator system
3Productivity
If the right-angled triangular part is small, then the cloth can be processed, but the clamping chuck may clamp the wrong side edge causing processing failure
Solution Approach 1:
The patent introduces a sensor as an intermediary between the cloth and the clamping system. The sensor detects the position of the right-angled triangular part and provides information to the control system, which then adjusts the holding device position accordingly. This intermediary mechanism ensures reliable identification and clamping of the correct edge even when the triangular part is small
Solution Approach 2:
The patent performs preliminary detection of the right-angled triangular part position using a sensor before the clamping action occurs. The holding device is positioned and adjusted based on this preliminary detection, ensuring that the clamping chuck will accurately clamp the correct side edge and preventing processing failures

AI summary
An edge clamping device includes: a two-position holding device 7 having a pair of holding chucks 71, 72 that hold two separate portions of a rectangular piece of cloth Y that are on or near the ridge of a fold, in a state where a right-angled triangular part S is revealed; an edge locating conveyor 8 that is disposed under the two-position holding device 7 and delivers the cloth Y having been released from the two-position holding device 7; clamping chucks 92, 93 disposed downstream of the edge locating conveyor 8 in a delivery direction; and a position changing means that moves at least one of the two-position holding device, the edge locating conveyor 8, and the clamping chucks 92, 93 in a crosswise direction such that the right-angled triangular part S of the cloth Y held by the two-position holding device 7 is located at a correct clamping position corresponding to the positions of the clamping chucks 92, 93.
