This is achieved with individuallycontrollable infrared tubular radiators,arranged in nine levels.This array allows temperature variation onthe preform. This temperature profile ensuresthe predefined material distribution, i.e., thebottle quality.To prevent overheating, the exterior of thepreform is cooled with fans.To prevent deformation, the sensitiveneck-finish area is protected by awater-cooled shield. In addition, cooled air isalso blown at the neck- finish area.The heating process takes approx. 20seconds. Afterward the preforms pass throughan equilibration zone for optimal distributionof the heat in the preform.Then a starwheel transfers the preforms to theblowing stations.After the preform enters the blowing station, the base mould is raised, and the entire mould is closed and locked.The heated preforms are held and fixed in place in the mould by means of the neck ring. This prevents deformation of the neck-finish.Even while the mould is being closed, the blowing nozzle descends, the stretching rod moves toward the end cap for stretching, and after a brief delay the pre-blowing air flows in. The duration of the delay determines the thickness of the material in the bottle base.Depending on the preform and bottle type, the pre-blowing pressure is 7-16 bar and lasts between 0.2-0.7 seconds, depending on the bottle size.At the end of the pre-blowing phase, the bottle is already fully shaped and material distribution is finished.The final blowing phase now begins, producing the finest contours of the bottle and pressing the material against the cold mould (approx. 10°C) for cooling.The higher the pressure, the better the cooling effect and the shorter the cooling time. The pressure ranges between 30—40 bar and is maintained for approximately 2 seconds. Afterward the stretching rod is retracted. Before the mould is opened, the pressure in the bottle must be released.Depending on the pressure and bottle size, this takes between 0.2—0.6 seconds and is baffled.After the bottle leaves the mould, it will shrink within 72 hours by 1%-2%.This process can be shortened by 5—15 minutes by preheating the mould(60—70°C).瓶子取出:The bottles are taken by the discharge starwheelThe bottles are transferred to the conveyor system.10瓶胚和瓶子的机械手机械手 瓶胚机械手The preforms are fed via a chute and steep belt conveyor to the top part of the unscrambler, where they are separated and then slide, with theneck-finish facing up, into the inclined infeed rail.After the infeed starwheel the preforms are transferred to the mandrels of the heating module.For optimal temperature distribution, the preforms revolve around their own axis, as they pass through the heating zone.After passing through the equilibration zone for optimal heat distribution in the preform, a starwheel transfers the preforms to the blowing station.瓶子机械手After the blowing process the bottle is transferred to the discharge starwheel. The blowing process is controlled by a pressure cam.Good bottles are transferred to the conveyor system. Faulty bottles are rejected into a bin.11。
克朗斯自动化生产线吹瓶机浅谈天津冶金职业技术学院毕业课题吹瓶机在自动化饮料生产中的应用及维护系别电气工程系专业电气自动化班级 2008级4班学生姓名高岡指导教师周敬2011年 5 月 5 日摘要随着人民生活水平的提高，饮料的市场需求量也不断增加，产品的质量就成为了生产厂商和消费者关注的问题。
人民生活水平的日益提高，对健康，绿色和营养食品需求日益增加，食品饮料制造商面临着就如何提高产品质量，满足日益严格的行业规范需求，提高产能，优化企业生产流程，缩短产品的上市时间，降低企业的生产和运营成本等很多问题。
而采用现代的自动化控制和管理信息系统，提高企业的信息化管理水平就是有效地解决以上问题的途径。
吹瓶、灌装、套标、喷码是影响PET饮料瓶质量的四道关键工序。
吹瓶机在自动化生产中是矿物质水生产中非常重要的生产设备,KRONES是世界知名的水处理公司,它利用西门子多种通信网络让S7-300读取各种接近开关、光电开关、压力开关、温度开关、传感器等开关量的状态,控制各种阀门、继电器、接触器、现场总线等,以实现CPU对这些设备的数据采集与控制。
