電腦控制型切花捆把機之研制

目前一般的捆把機，其捆紮圈數及捆綁中的捆紮緊度是固定的，如要調整捆紮圈數及緊度，其機構的修改實非易事。本研究整合機械與電腦，開發以微處理機控制之切花捆把機，除了能夠有效控制捆把機的捆紮及打結動作外，對於捆紮圈數及捆紮緊度，能夠提供彈性且便利的調整。機構中之雙勾針打結部及繩子張力調整部的設計，能夠充分配合微電腦的控制方式，達成確實的打結及調整繩子張力的功能。以菊花為試驗材料，機械捆綁作業每把約13秒，每小時的作業能量為278把，人工捆綁作業每把則為22秒。經振動篩模擬運輸振動兩小時，紮繩均無鬆脫現象，顯示人工與機械兩種作業的捆綁效果同樣良好，且緊度適宜。利用變異數分析機械捆綁與人工捆綁作業對菊花品質的影響時，以1%的顯著水準檢定，結果顯示兩種作業方式對菊花捆綁後的瓶挿品質無顯著差異，亦即以機械捆綁的處理對菊花日後瓶挿的影響不大。

The adjustment of the number of loops and the tension of binding string is not feasible for the binders commercially available. It usually involves a modification of mechanism design, which is not easy. In the design of the developed binder, microprocessor technology and mechatronics were integrated for controlling the performance of binding and knotting, and for easy adjusting of binding loops and tension. The dual-needle knotting unit and string tension adjuster were designed and operated through a control algorithm in a microprocessor. Chrysanthemum cut flowers were used as experimental samples. The performance of the developed binder showed less handling time (13 versus 22 seconds) when comparied with hand operations, and a working capacity of 278 bunches per hour was reported. It also indicated that both binder and hand operations gave good binding tension after a simulation of transportation for two hours by a vibrator. The statistical analysis of variance showed no significant difference in the quality of vase tests between the binder and hand operations at the significance level of 1%.
