A material handling system (MHS) can be simply defined as an integrated system involving activities smaterials. Material handling systems (MHS) range from simple pallet rack and shelving projects, to complex conveyor belt and Automated Storage and Retrieval Systems (AS/RS). The primary objective of using a MHS is to ensure that the material in the right amount is safely delivered to the desired destination at the right time and at the minimum cost. The MHS is properly designed not only to ensure the minimum cost and compatibility with other manufacturing equipmenalso to meet safety concerns.

4.2. MATERIAL HANDLING SYSTEM

The material handling system has included some of devices and hardware. The overview of this system is the container start at the left of the conveyor and place at the conveyor. Relays act as switch and change the direction of motor. When Relay A and B is powered, the conveyor will move the container from starting point to right. When the container arrives at proximity sensor 1, proximity sensor 1 will trigger and conveyor stopped. During that time two ball will drop into the container. Then, conveyor move to right until it reaches at proximity sensor 2. At this point, another two ball is released. The container move to left and stop again at proximity sensor 1 place and release two ball. Finally, the container move to right again and collect last two ball and move to the end of the conveyor before its stop. Figure 6 shows the complete set of material handling system. For each of the set of wire need to label and the wire need to connect correctly to prevent from short circuit. Figure 7 shows wire is labeled correctly before its connect to the material handling set.

For each GPIO pin, we need to declare as input or output. This is because the GPIO pin is programmable. Table below show that each device is declared an unique name and each of them assign a GPIO pin.

to the Raspberry Pi because it is operated in 5 V, in addition of Raspberry Pi also can supply 5 V

Raspberry Pi can’t drive the output device consisting of

high voltage but it also need high current supply. We need to careful when connecting this output device so that high current supply not leak to the Raspberry

s project, we are using a TIP41C NPN power transistor to each of the solenoid and relay that act as switch. When the power transistor received a low current signal from the Raspberry Pi

ther solenoid of relay.

We manage to integrate all the input and output device to the Raspberry Pi and runs test to every single of them. All of them are function correctly. But there is problem when we run the input

because of noises that exist. In addition, the power

The programming of the Raspberry Pi is easier compare to PLC ladder diagram. Each of the GPIO pin can be declare but the input and output pin for PLC is fixed with the address. That’s why our group decided to use the Raspberry Pi as core of the system to drive MHS.

CONCLUSI N

By doing this project, now we already know how to develop a material handling system by integrating various sensor and actuation system by using Raspberry Pi microactually very suitable for industrial uses, especially for industrial control processes. The low cost computer is extremely customizable and for many businesses trying it out makes sense. Raspberry Pi is integrated, the device has many uses and advantages over elements of existing IT. The uses of Raspberry Pi are better than programmer logic control (PLC) in term of cost, time and easy use. That’s why we chose Raspberry Pi while doing year there will be more group that use Raspberry Pi so that they can discuss among them then can make the system better and solve the existing problem.

CONCLUSI N

By doing this project, now we already know how to develop a material handling system by and actuation system by using Raspberry Pi micro-controller. It is

actually very suitable for industrial uses, especially for industrial control processes. The low cost computer is extremely customizable and for many businesses trying it out makes sense. Raspberry Pi is integrated, the device has many uses and advantages over elements of existing IT. The uses of Raspberry Pi are better than programmer logic control (PLC) in term of cost, time and easy use. That’s why we chose Raspberry Pi while doing this project. We hope next year there will be more group that use Raspberry Pi so that they can discuss among them then can make the system better and solve the existing problem.

By doing this project, now we already know how to develop a material handling system by controller. It is

actually very suitable for industrial uses, especially for industrial control processes. The low cost computer is extremely customizable and for many businesses trying it out makes sense. Once Raspberry Pi is integrated, the device has many uses and advantages over elements of existing IT. The uses of Raspberry Pi are better than programmer logic control (PLC) in term of cost,

this project. We hope next year there will be more group that use Raspberry Pi so that they can discuss among them then
