螺旋塔式食品冷却装置的研制
摘要
摘要:螺旋塔式食品冷却装置由PLC控制系统、双轴联动系统和转送带转送系统等组成。工作人员可以通过操作触摸屏控制PLC,在驱动接触器,双电机及传送带等,实现对双电机、传送带等执行元件的控制运行。
螺旋塔式食品冷却装置的运动过程:系统通电后按下启动按钮传送带开始运行,当位于传送带初始端的光电传感器检测到有物体通过时,工作人员根据物体的大小来调节触摸屏上传送带的速度以达到食品冷却的目的,食品通过传送带从螺旋塔的塔顶进入螺旋塔内,在限定的速度下转动,通过一定的时间转送出螺旋塔,如此重复完成一个过程。在此过程中可根据食物的大小来设置所需冷却的时间,或用示教功能来设置速度的参数。

Abstract
Abstract: spiral tower food cooling device is controlled by PLC system, biaxial linkage system and itransfer belt transport system, etc.Staff can be operated by PLC and touch screen control, drive contactor n double machine and conveyor belt, etc., realize the control of executive components such as double motors, conveyor belt running.
The motion process of spiral tower food cooling device: press the start button after the power supply system conveyor belt is up and running, when the conveyor belt to the initial photoelectric sensors to detect objects through, staff will adjust according to the size of the object on the touch screen to achieve the purpose of food cooling at the speed of conveyor belt, food through the conveyor belt from the top of tower tower, under the limit the speed of rotation, through a certain amount of time transfer out of the tower, repeat to complete a process.According to the size of the food in the process to set up the required cooling time, or use the teaching function to set the speed parameters.
Keywords:PLC;The cooling system;The conveyor belt;Touch screen;The sensor
