Sheet Manufacturing System with Networked Material Level Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing sheet manufacturing systems face challenges in determining the appropriate transport of coarsely crushed paper pieces from a coarsely crushing apparatus to a sheet manufacturing apparatus, especially when they are installed in separate locations, due to the lack of real-time information on the remaining amount and allowable filling capacity of the reserving sections.
Innovation Solution
A network-connected sheet manufacturing system that includes a coarsely crushing apparatus and a sheet manufacturing apparatus, equipped with remaining amount detectors, calculation sections, and output sections, which transmit information about the allowable filling amount to a server, allowing for display of this information on both systems, enabling accurate determination of when to transport and replenish coarsely crushed pieces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the coarsely crushing apparatus and sheet manufacturing apparatus are installed in separate locations, then the raw material supply can be extended beyond the installation spot, but it becomes difficult to obtain real-time information on the remaining amount and allowable filling capacity
Solution Approach 1:
The sheet manufacturing apparatus transmits information about the remaining amount of coarsely crushed pieces and the allowable filling capacity of its reserving section to the coarsely crushing apparatus through a network connection. This feedback mechanism enables the coarsely crushing apparatus to display real-time information, allowing operators to determine appropriate transport timing even when the two apparatuses are located separately, thus maintaining continuous operation capability without information loss.
2Quantity of substance
If the coarsely crushing apparatus is located separately, then more raw materials can be supplied to the sheet manufacturing apparatus, but it is not possible to easily determine when to transport the coarsely crushed pieces
Solution Approach 1:
The system establishes a network connection where the sheet manufacturing apparatus provides feedback information about its reserving section status (remaining amount and allowable filling capacity) to the coarsely crushing apparatus. This enables the operator at the coarsely crushing apparatus to easily determine the optimal transport timing based on displayed information, maintaining ease of operation even when the apparatuses are separated and large quantities of raw materials need to be supplied.
3Adaptability or versatility
If worker manually collects and transports coarsely crushed pieces between separate locations, then raw material supply can be extended, but the operation becomes more complex and requires manual intervention
Solution Approach 1:
The network-connected feedback system automatically transmits information about the sheet manufacturing apparatus's reserving section status to the coarsely crushing apparatus. This automated information exchange simplifies transport management by providing clear, real-time guidance on when transport is needed, reducing the complexity of managing flexible raw material supply across separate locations without requiring complex manual coordination.

AI summary
A sheet manufacturing system includes a coarsely crushing apparatus that coarsely crushes a paper; a sheet manufacturing apparatus that generates a sheet-shaped recycled paper using coarsely crushed pieces of the paper as a raw material; and a server that is connected to the coarsely crushing apparatus and the sheet manufacturing apparatus via a network, in which the sheet manufacturing apparatus has a reserving section that reserves the coarsely crushed pieces, a remaining amount detector that detects a remaining amount of the coarsely crushed pieces in the reserving section, a calculation section that calculates an allowable filling amount of the coarsely crushed pieces in the reserving section based on a detection result of the remaining amount detector, and an output section that transmits information related to the calculated allowable filling amount to the server, and the coarsely crushing apparatus has an integration section that integrates the coarsely crushed pieces, an input section that acquires the information related to the allowable filling amount from the server, a display information generation section that generates display information related to the allowable filling amount based on the information acquired by the input section, and a display section that displays the display information.
