半自動拉布機設計

畢業(yè)設計，包括完整CAD圖


摘要
拉布也稱為鋪料，就是根據裁剪方案所確定的排料長度和鋪料層數(shù)，將面料一層一層地鋪在裁床上。拉布的工藝要求是：布面平整、布邊對齊、減小張力、方向一致、 對正條格、長度準確。拉布機就是實現(xiàn)拉布工藝的一種紡織機械。拉布機按其運動方式可分為兩類：固定安裝式和移動式。固定安裝的拉布機結構簡單，適合小型制衣廠使用。移動的拉布機按其自動程度又分兩種形式：一種是手動拉布機；另一種是半自動和自動拉布機。在競爭已經白熱化的服裝行業(yè)，沖出市場、搶先在競爭對手的前面； 有效地控制成品的品質、 成本、 和效率; 這些因素已顯得極為重要。在“裁剪”的工作環(huán)節(jié)里, 使用拉布機具有保證品質, 減低成本, 提高效率的優(yōu)勢。文章首先回顧了中國紡織機械的發(fā)展歷程介紹了拉布原理及各種拉布方法，然后制定了拉布機的總體設計方案對拉布機進行了受力分析及零部件設計，其次用單片機實現(xiàn)了整個系統(tǒng)的自動化控制，最后用PRO/E對拉布機進行了實體造型。其中，控制系統(tǒng)采用MCS51 系列單片機A T89C51作為處理器系統(tǒng)，并采用了增量式光電編碼器的伺服驅動器；文章闡述了用PRO/E進行拉布機實體造型的基本思路，并詳細記述了齒輪和減速器箱蓋的造型步驟。通過PRO/E對拉布機的造型，使得實際生產時能更加直觀地理解設計者的思路，減小了生產裝配時出現(xiàn)錯誤的可能性。

Abstract
Spreader also known as Accessorier. Based on the length and spreaded layers established by the cutting programme, fabrics will be accessoried on the cutting bed.The technological requirements of spreading are: the unknit of cloth cover, the cloth-line, the reduction of tension, the same direction, the same stripe, the accuration of length.Spreader is a kind of textile machinery which spreade cloth.Spreader according to their moving methods can be divided into two categories. One is manual Spreader; the other is semi-automatic and automatic Spreader. In the apparel industry the competition is fierce. Occupation of the market, the initiative, the effective control over the finished product quality, cost and efficiency, these factors has become extremely important. In the "Cutting" part of the work, the use of spreader can guarantee quality, reduce costs, and improve efficiency. The article first reviewed the china textile machinery course of development, introduced the principle of spreader and various spreading methods. And then developed a design programme of spreader, analyzed the mechanical and designed the parts. The whole system of automatic control was done by the SCM. Finally spreader was solid modeling by using PRO / E. Among them, the control system used A T89C51 of MCS51 MCU as the processor system and adopted the incremental photoelectric encoder servo drives. The article described the basic ideas of solid modeling of spreader by using PRO/ E and given detailed modeling steps of the gear and the reducer covers .According to the solid modeling it is easier to understand the designer's idea and can reduce the possibility of errors when it is producted.
