Design and development of automatic loading and unloading of moulding box in heat moulding machine

In heat moulding machine required shape can be obtained from the raw material at temperature range of 200 to 250 °C. The raw material used in the heat moulding machine is rubber and the melting temperature of rubber is 180 °C. In this process loading and unloading of moulding box is done manually. Hence heat produced inside the moulding machine may harm the operator or worker. Sometimes it leads to major accident for workers. If the worker continuously working in the hot zone may cause skin problem. To overcome this problem small table is designed with the help of pneumatic cylinder the loading and unloading process done automatically. Micrologix 1000 PLC is used to control the whole process. Wiper motor is used to move the table from one place to another place. The targeted position is sensed by the induction type proximity sensor. By the above mentioned components loading and unloading of moulding box is done automatically and the operator's safety will be assured.
