手持式芒果套袋機具之研發

The Development of Hand Carried Bagging Machine for Mango on the Tree

Abstracts


芒果為本省重要經濟果樹之一,每年為果農帶來龐大收益。惟芒果不論內外銷,為提高果實品質及避免受病蟲害之侵襲,在芒果未成熟前均投入相當人力在田間給予每粒芒果各別作套袋處理,對於病蟲害之防治、農藥污染證實最為實際有效。目前芒果直接在果樹上之套袋仍然以人工作業為主,所需勞力頗為密集,不但辛苦且耗工,因此套袋機具極待研究開發。本計畫仍以開發小型手持式芒果套袋機具以取代人工,研發完成套袋機可在田間進行果樹上直接套袋,機動性高,操作方便,從果袋吸取、拉開袋口、封袋完成等一聯串的動作,可進行連續作業,平均每小時可套好果實約85~100粒之間,與人工比較作業速度慢2.4倍,探討其原因係芒果結果位置在芽條葉梢頂端,果實之間的分佈頗為密集及重疊,造成套袋作業困難度,加以在套入果實後封袋過程中以熱溶合PE塑膠膜所需時間長達30~40sec,因此作業效率有待進一步研究與改進。

Mango is one of the important economy fruits in Taiwan, and generates big revenue to growers every year. However no matter to consume locally or export, to protect mango from diseases and insects is an important task for growers in order to produce high quality fruit. Before harvesting, growers have to use tremendous labor to bag individual fruit on the tree, which is proven to be the most efficient wav to protect from disease and insect, and to reduce the chemical contamination. At present, farmers only use hands to complete the bagging work in the fruit field. it is a very labor intensive and labor cost work. Therefore the farmers need a handy tool to assist the bagging work in the field earnestly.The object of this project is to develop a handy tool to bag mango on trees to reduce the labor cost. The developed handy bagging machine can be used in the field to bag the fruits on the tree directly. The mobility of the developed tool is good, and it can be operated in the field easily. The tool can sequentially and continuously be used by a grower to complete the following works: sucking bag, opening bag, and sealing bag. The developed tool can operate in the speed of 85-100 bags/hr. The operated speed is 1/2.4, as comparing to speed of pure labor. Due to position of mango is around the bud tip of the bud tip of tree, of the tree, fruits are placed very close and even overlapping; therefore, it makes the bagging work to become more difficult. Otherwise, the sealing process needs 30-40 seconds to melt PE plastic to complete the sealing work. Due to the lack of efficiency of the developed tool, the further study will be conducted to improve its operating speed and efficiency.
