Cloth spreading device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cloth spreading devices experience inefficiencies due to waiting time for workers as the input chuck remains standby until the cloth is transferred to the transversely moving chuck, limiting production efficiency.
Innovation Solution
The device incorporates multiple input units with up-down moving chucks, relay units with circling members, and extension units with transversely moving chucks to facilitate continuous cloth processing, allowing the input chuck to move down immediately after transferring the cloth to the relay unit, thereby reducing waiting time and enhancing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single input chuck is used in the existing cloth spreading device, then the structure is simple, but the worker experiences waiting time and production efficiency is reduced
Solution Approach 1:
The device is divided into multiple independent input units (first input unit with first input chuck, second input unit with second input chuck) that can operate simultaneously. Each input unit has its own relay unit and extension unit, allowing parallel processing of multiple cloths without worker waiting time, thus improving productivity while maintaining manageable complexity through modular design
Solution Approach 2:
The relay units are positioned to receive cloths from input chucks before the extension units process them. This preliminary action allows the input chucks to release cloths quickly without waiting for the extension units to be ready, eliminating worker waiting time and enabling continuous operation
2Loss of time
If the input chuck waits for the transverse chuck to be ready, then the transfer is coordinated, but the worker cannot attach the next cloth and time is lost
Solution Approach 1:
The relay units are positioned and configured to receive cloths from input chucks immediately when the input chucks move upward, before the extension units need to process them. This preliminary receiving action allows input chucks to release cloths without waiting for extension units, eliminating worker waiting time and enabling continuous operation
Solution Approach 2:
The relay units act as intermediary components between the input chucks and extension units. They receive cloths from input chucks and transfer them to extension units, decoupling the timing requirements of these components and allowing input chucks to operate independently without waiting for extension units to be ready

AI summary
To provide a cloth spreading device capable of shortening the waiting time until inputting work of a worker and achieving high production efficiency. A cloth spreading device 1 includes: a plurality of input units 30; a plurality of relay units 40 provided corresponding to the input units 30; and an extension unit 50. Each of the input units 30 includes: an input chuck 31; and an up-down moving machine 32 that moves the input chuck 31 up and down. Each of the relay units 40 receives a cloth C from the input chuck 31 having moved up to a transfer position and transfers the received cloth C to the extension unit 50. The input chuck 31 having transferred the cloth C to the relay unit 40 moves down to an input position. Standby time of the input chuck 31 until the relay unit 40 becomes ready to receive the cloth C can be shortened so that the input chuck 31 can be moved down without delay to the input position.
