臺灣博碩士論文加值系統

本研究使用秤重模組取代重量控制器，兩者進行比較，秤重模組能節省成本超過80%、縮小體積約89%，並追求更快速的傳輸，將簡化複雜的配線，把通訊更改為內部傳輸。本論文以秤重模組搭配PLC，模擬架構重量控制器的順序控制自動充填計量系統，以Ethernet高速乙太網路通訊方式，使用TCP/IP協定與上位電腦連結傳遞生產相關的計量數據，並搭配人機介面HMI，在觸控式面板完成重量校正、參數修改、自動計量與手/自動切換控制等功能，讓新機或更換故障品在配線完成後，即能在人機上操作使用，無須如重量控制器，需經專業人員設定後才能運作。
導入自動計量生產後，原本須由人工根據原料品項，逐一使用電子秤手動計量，變更為每筆配方傳遞至所有機台後能夠同時計量，配方平均完成時間，由原本的12~20分鐘縮短為5分鐘，效率提升約為原本的3倍，人員的調度，由原本輪3班配合現場配料，縮短為每日1班，即可將當日所需配料完成，大大降低人事成本，達到省時省力的目標。

In this thesis the weight control module, is used to replaces the weight controller. It can save the weight control costs over 80%, and reduce the weight control size over 89%. Besides, the pursuit of faster transmission and simplify the wiring, changed the communication to internal transmission. By using PLC matches and imitates the automatic control quantity fill. This system adopts the Ethernet communication, using the TCP/IP computer link to transmit related data, and to match with HMI, to assist the touch panel to complete the calibration, parameter modification, automatic calculation and manual/auto switch over the control functions. It makes the new machine or broken accessory is changed after the wiring completion, it can be operated on the HMI touch panel, it doesn’t like the weight controller needs to be set by professional operator.
By adopting this system into the automatic quantity filling, the one cycle finish time 12~20 minutes of manual quantity filling can be shorten to 5 minutes by automatic quantity filling. Compare to the manual quantity filling system the overall efficiency of the automatic quantity filling increase about 3 times. It can reduce the labor cost hugely. That is the main contributions of this thesis.
