臺灣博碩士論文加值系統

舉凡各種貨物為方便大批量搬運、裝櫃，除須先以紙箱包裝外，接下來使用棧板堆疊，則是後續重要的程序之一。螺絲產業在台灣擁有舉足輕重的地位，其出口貿易更占台灣出口總值相當的比例，對於散裝螺絲包裝來說，大部分都還須仰賴人工作業，其流程從倉庫吊運卸料、紙箱貼標、過磅、震動扎實、封箱、逐一搬運堆疊上棧板等等，皆全由人工完成，其中又以搬運包裝好的紙箱，逐一堆疊到棧板是非常耗費體力的一項工作流程。一般來說更是無法掌握固定的產能及成本效益的，因而導入自動化是有其必要性。
本文以現有散裝螺絲包裝堆疊機作為改良研究，由原來人工操作三組手動氣壓閥來完成紙箱堆疊方式，改由機構與電機控制整合，利用PLC可程式控制器，結合油壓系統、氣壓系統，搭配各式控制元件，光電開關限制開關、氣、油壓電磁閥及提升馬達速度的變頻器，來編輯自動化程式控制模式，讓順暢的自動化堆疊機功能更可發揮淋漓盡致，藉此改善工人逐一堆疊到棧板，效能不彰的窘境，進而節省人力、降低成本、增加生產力、提高品質及競爭力。而在順利改良堆疊機後，其結果顯示自動化後減少人力付出，效率也提高 ，產能也由每日13組棧板，變為每日22.6組，產能更是大大提升近73.8 %。

For conveniently and largely carrying and loading various goods, besides the initial carton packing, stacking the goods on pallets is one of the following important procedures. The screw industry plays a crucial role in Taiwan, and its export trade accounts for a considerable proportion of Taiwan's total export value. However, most of bulk screw packing still rely on manual work. The entire processes, from warehouse lifting and unloading, carton labeling, weighing, vibration solid, carton sealing, to stacked on pallet one by one, etc. are all done manually by workers. Among them, moving and stacking the packed cartons on pallet one by one is very physically laborious. This way is generally impossible to control the fixed capacity and cost-effectiveness. Therefore, it is necessary to apply automatic mechanism.
This paper aims to improve the existing bulk screw packing stacker, which was run by operating three sets of manual pneumatic valves to complete the carton stacking job. In order to improve the stacker, the researcher integrated the mechanism and electronic control, employed the programmable logic controller (PLC), combined the hydraulic system and the air pressure system, matched various control elements, such as photoelectric switches, limit switches, pneumatic and hydraulic solenoid valves, and variable-frequency drive witch can increase the speed of the motor to edit an automation program control mode, so that the automatic stacker can work well and effectively. Therefore, this way improves the ineffectively way of stacking the cartons on the pallet one by one, as well as saves manpower, reduces costs, increases productivity, enhances quality and competitiveness. Consequently, after the stacker improved successfully, the results of this machine shows that the manpower cost is reduced, the effectiveness is promoted, the productivity is enhanced, and the production capacity is increased from 13 sets of pallets to 22.6 sets per day, greatly added up nearly 73.8 %.
