摘要
沖床設備被廣泛應用在沖壓成型加工，其沖壓件具有重量輕、厚度薄、剛性好和質量穩定等優點，但由於傳統的沖床設備採用機械式送料機或是手工送料的方式，所以會存在著效率低、速度慢、精度較低、操作人員有安全顧慮等之問題。故本論文之目的為針對高速沖床設備建立一套自動化送料系統，利用數控伺服送料機取代原有的機械式送料機，以實現自動化送料加工。該系統主要是應用控制器控制驅動器與伺服馬達並與可程式控制器做溝通，並經由編碼器與感測器模組之組合達成回授位置與速度訊號目的，此外，送料機的加工參數亦可適當地修改以提高沖壓加工之靈活性。經由實驗結果顯示，針對不同的送料長度時，其相對誤差之最大值為0.20mm，該誤差仍在容許範圍內，證實此送料系統進行實際送料是可行的。

Presses are widely used in stamping and molding processes. The advantages of press mold accessories are light weight, thin thickness, good stiffness, and uniform mass. However, traditional presses adopt mechanical feeding or hand-feed methods. These approaches lead presses to inefficient, slow speed, low accuracy, and safety problems for operators. Therefore, this thesis aims to design an automatic feeder for high speed presses. It employed the numerical control for a feeder to replace the mechanical scheme in order to achieve the automatic feeding process. The system used a controller to control the servo drive and motor of the feeder, and communicate with the programmable logic controller. The position and speed signals of the motor can be obtained by an encoder with the sensor module, and then the parameters of the feeder can be suitably modified to improve the flexibility of pressing. Experimental results show that the feeding in different length, the maximum value of the relative error is 0.20mm. This error is acceptable for the range of tolerance, and the proposed feeding system is feasible
