Conveyor which is mechanical which transmits n material in a certain line is the intensity of essential machinery and equitment，to increase productivity and reduce the labor. conveyors are widely used in mining, food, metallurgical and other industries.The design of the vertical and horizontal conveyor of packing machine d is a roller conveyors, which not only conveyor to the packing box full of food bags from the packaging machine to the end of a device。 but also can push the packing box out of the production line 。The vertical and horizontal conveyor of packing machine can be horizontal and vertical transmission：in the vertical， the transportation device is powered；in the horizontal，the power devices are situated， when the bad packing box which is not full of food is detected，the power device will work together to launch the bad packing box out of the production line。In order to reach this effect, its power plant must be corresponding fast。 so in the horizontal transmission road power plant it is necessary to add the electromagnetic clutch。In general, the electromagnetic clutch does not work, when there are unqualified box, the central controller give issue commands, then the electromagnetic clutch work. In the front-end the conveyor are equipped with infrared sensors to detect the compliance box.The system design fully take into account that the part can be replaced, In the choice of gear, design-driven devices, timing belt pulleys, it have adopted some of the most common type, and I optimization the parameters of machine structural ，determine the size parameters of the conveyor belt and calculate transmission， While I make the strength analysis of the Side roller and roller and check the life of roller bearings and sprockets ,in order to meet requirements., I model the part and make its two-dimensional drawings with SolidWorks2007.This article is a record of the design .every hour ，this machine can detecte 700 or so boxes，thereby increasing productivity, lowering production costs.Key words: transportation equipment production line infrared sensor - 3 -第1章 绪论1.1问题的提出随着我国综合国力的提高，人民生活素质的提高，在我国，一个行业包装机械也迅速成长。早在上个世纪，包装机就已经在我国出现，尤其是进入改革开放后，由于国民经济迅速发展，对外贸易不断扩大，人民生活水平明显提高，对产品的包装要求越来越高，更促使了包装机械工业的成长。进入了21世纪，为了早日实现小康社会，包装机进入了全面革新换代。其更新换代的主要是：
