半自动拉布机设计

毕业设计，包括完整CAD图


摘要
拉布也称为铺料，就是根据裁剪方案所确定的排料长度和铺料层数，将面料一层一层地铺在裁床上。拉布的工艺要求是：布面平整、布边对齐、减小张力、方向一致、 对正条格、长度准确。拉布机就是实现拉布工艺的一种纺织机械。拉布机按其运动方式可分为两类：固定安装式和移动式。固定安装的拉布机结构简单，适合小型制衣厂使用。移动的拉布机按其自动程度又分两种形式：一种是手动拉布机；另一种是半自动和自动拉布机。在竞争已经白热化的服装行业，冲出市场、抢先在竞争对手的前面； 有效地控制成品的品质、 成本、 和效率; 这些因素已显得极为重要。在“裁剪”的工作环节里, 使用拉布机具有保证品质, 减低成本, 提高效率的优势。文章首先回顾了中国纺织机械的发展历程介绍了拉布原理及各种拉布方法，然后制定了拉布机的总体设计方案对拉布机进行了受力分析及零部件设计，其次用单片机实现了整个系统的自动化控制，最后用PRO/E对拉布机进行了实体造型。其中，控制系统采用MCS51 系列单片机A T89C51作为处理器系统，并采用了增量式光电编码器的伺服驱动器；文章阐述了用PRO/E进行拉布机实体造型的基本思路，并详细记述了齿轮和减速器箱盖的造型步骤。通过PRO/E对拉布机的造型，使得实际生产时能更加直观地理解设计者的思路，减小了生产装配时出现错误的可能性。

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.
