Many different parts make up the powder packing machine. The packager would not function correctly without each piece. The PLC and HMI serve as the brains of the packaging machine.
Let’s talk about the packing machine’s most essential parts.
Programmable Logic Controller (PLC)
PLCs are a microcontroller that controls processes by implementing logic, timing, sequencing, counting, and arithmetic operations. Ladder logic is used to carry out the operation. The DVP family of PLCs from Delta is used in various industrial automation equipment due to its speed, stability, and durability. The Delta DVP14SS2 PLC, which has eight input ports and six output ports, is utilized in the packaging machine. It is a 32-bit PLC with an 8-K-step programming capability.
Human Machine Interface (HMI)
An HMI is a user interface that allows you to interact with automation technologies. The HMI solutions provided by Delta provide a variety of communication interfaces for quick communication and control of diverse machinery, processes, and operations. The touch is resistive, and gloves may be used to prevent direct touch. It allows fast system creation, reduces wiring and installation time, reduces running costs, and boosts system efficiency by eliminating time-consuming adjustments and additional maintenance expenditures. In the powder packing machine, a Delta VS070HE-1 HMI with a resolution of 800 x 480 is used. There are two USB ports and one RS232 COM port.
Switched Mode Power Supply
A switching regulator is used in an electronic power supply system to transmit electrical power correctly. It is a specific power supply unit that adjusts voltage following computer specifications and is common in computers. SMPS may modify the output voltage and current for various electrical designs by modulating the basic building blocks of normally lossless storage, including capacitors and inductors. In SMPS devices, switching regulators turn on and off the load current to maintain and control the output voltage. SMPSs rotate through low energy loss, full-on, and full-off phases. They consume significantly less time in high dissipation cycles than linear power supplies, resulting in less depletion.
A relay is a safety mechanism used to safeguard electrical circuits, switch between circuits, and provide power to equipment that needs much of it. Every single circuit has its relay for self-protection. The relay protects the circuit components from damage caused by an overflow of current. Relays also apply in the packaging industry to protect parts from excessive current flow. There is an MY4N DC24 relay in the packaging machine. There’s a DC capability and a 7A-rated current.
Solid State Relay
An SSR is a compact integrated circuit (IC) and discrete component device that functions as a contactless electronic switch. It can quickly change the state of an electrical circuit in the same way that mechanical relays do. There is no mechanical motion or moving parts inside the SSR during the switching process. Because of how it works, the Solid-State Relay is often called a non-contact switch. It is more reliable than electromagnetic relays, and its ability to amplify and drive makes it a great way to power high-output actuators (EMR). Switches that control solid-state relays use a minimal amount of power. This means that very small control currents can control even large load currents. Optoelectronic isolation technology keeps the input and output terminals of the relay from touching each other electrically.
Miniature Circuit Breaker
An MCB is an electrical switch that immediately cuts power to a circuit when the network is unsteady, such as when it is overloaded or has a problem. The constant current going through the MCB heats and turns off the bi-metallic strip. This causes the circuit to break, which stops the flow of electricity. To use the circuit breaker (MCB), manual activation is a must. In a short circuit, on the other hand, the current quickly goes up, which makes the solenoid-connected nozzle move electromechanically. The latch mechanism is released as soon as the nozzle touches the trip lever and the circuit breaker connections open.
Fill packaging with grains and peel off rolls using electric motors. Drawing the laminates for 160 mm in 0.1 seconds increases production throughput. A motor with a 0.5 HP capacity is essential to run the food grain at 1400 rpm to fill the packets with the proper amount of food grain. To draw the laminates quickly enough, you’ll need a 0.5 HP capacity and a speed of 955 rpm motor. The available motor of a powder packing machine can be more potent by using a three-to-one gear ratio.
The powder packaging machine cannot function without the motor drive. This part regulates the power supply to the motor. A drive system consists of a motor and a drive. The motor’s rotational velocity is adjustable using the drive’s frequency modifications. Each kind of motor—AC, DC, and Servo—has its dedicated motor drive. This application uses an AC drive. This drive’s features are flexible to meet the needs of each operation.
Without making contact, a proximity sensor may detect surrounding objects. An electromagnetic field or beam that changes in return signal in response to nearby objects may be used. Proximity sensors must be magnetic, inductive, and capacitive for targets made of plastic, metal, and other materials. It picks up objects or products within the normal range of a proximity sensor. As proximity sensors don’t contact the object directly and don’t have any mechanical parts, they are dependable and long-lasting.
In a powder packing machine, the Selec TC533 temperature controller has both on/off and PID control options. It has Thermocouple and RTD inputs. Using a relay or SSR gives control over a specific area.
In electronics, many measuring tools apply for different tasks depending on their needs. A single sensor, such as a weight sensor or load cell, measures weight. The most common use for this sensor is for determining a weight for various purposes. As weight sensors are accurate and consistent, they are best in weighing systems. Load cells translate loads into electrical signals. The signal may shift in voltage, current, or frequency based on the load and circuit. This sensor measures force, weight, or pressure and provides a proportional value. It turns a force such as tension, compression, pressure, or torque into a quantified and regulated electrical signal.
Vibrator and Feeder
Pack food grains consistently, quicker, and securely using a vibration-based feeder and a scale controlled by an automated switch. As a matter of fact, vibration helps distribute materials inside the packaging as well as other components, cutting packing and running costs. Using vibration technologies boosts productivity as well. As a result, vibrator-based industrial packaging solutions may be scaled to satisfy the requirements of both big corporations and relatively small firms.
In low-power settings, actuators like pneumatic cylinders are standard. There are a lot of different designs for pneumatic cylinders, and each one is best for a particular working pressure and other factors. In a powder packager, small cylinders seal the lid and open and close the weighing hopper. These cylinders can help segregate packets and print dates. A powder packaging machine uses small A51 and A52 cylinders.
