INVT TS621 PLC and VS-QS HMI Power Smart Grain Weighing & Packing Machine

Abstract: This machine will use to pack the storage grains in to bags. Packing will done based on the weight. Our TS Series PLC & VS series HMI used for this application and all data’s are moved to their IOT device.

Keywords: TS621, VS-QS

Project background: 

Mainly this machine will use for automatic rice mills, wheat packings. Used this to pack the grains based on the weight. Peeled rice will store in to the storage cabins in bulk quantities (will be in TONS). Customer will pack the grains based on their orders from the storage. Storage cabin connected with load cells, to measure the overall storage quantities. Also the bag packing system also have a load cell to measure every bag weight as per the customer requirement. 

Our customer is a SPM for rice mill related machineries. So they are import this machine with inbuilt controllers. Those controllers will fix at top side of the machine, so it’s not comfortable to access the HMI by end user. So our customer want to add one more HMI at bottom of the machine for easy access to the user (like separate operator panel). For this purpose we used our VS070-QS HMI for easy user operation. Also they want to move all real time data’s (Balance stock, packed grains per day, running hours etc...) to the IOT device. 

Challenges & Solutions:

i)    User always go to the machine top by using any ladder to access the HMI. It’s not user friendly HMI model.

ii)    They have several types of machines. Some machines will have two or three controllers for both loading and unloading functions. So user need to go one side for loading HMI access and unloading they have to go for another side of the machine to access the HMI.

iii)    Moving all data’s to IOT device for continuous monitoring and recording the data’s. 

We give our VS070-QS HMI & TS621 PLC for this application to overcome the all above challenges. Machine inbuilt HMI controllers will connect with TS621PLC through Modbus TCP/IP Communication. Single controller or multiple controller any type of machine will connect with this one PLC. PLC connected with our QS HMI and it will fix at bottom of the machine also we are given one HMI Program for multiple controllers. So that user can access all controllers from the one HMI. Also all data’s moved from PLC to IOT device through Modbus TCP/IP Communication.

Introduction 
 

MACHINE PROCEDURE:-

A. Grain inlet area: First raw grains entering from the storage area in to this big funnel for packing.

B. Weighing controller: This unit will measure the weight of the grins moving to packing. Required weight will set in the HMI screen. When actual weight is reached to the set weight, weighing controller will give the feedback to the PLC. Based on this feedback PLC will close the valve.

C. Packing and sealing: After closing the Valve, grain bag will seal by sealing unit.

D. Conveyor: After the bag sealing, conveyor will move in to the storage area.
E. Bin stock function: Grain storage will be a multiple bins. Each bins have minimum 2TON to 3TON storage capacity. Feedback will give to the PLC from all bins for minimum and maximum level. If one bin storage will goes to the minimum level, then system will close the bin valve and open the next bin valve. Then minimum level bin ready to fill the stock.

E. IOT Function: All stock data’s and unloading data’s are move in to the Customer’s IOT device. And also VNC function has been enabled. So that customer can monitor and control the HMI screen from their office PC.

Advantages and benefits

•    Easy and customized HMI Programs for user friendly operation.
•    All data’s are moved to the IOT device. So that customer can monitor the stock level and alarms and more details from anywhere.
•    VNC function will more convenient for monitoring and control the HMI screens.
•    Historical data collection for all bin stocks. Can copy the data’s by using U disk.

Conclusion 

Easy operate the machine because of simplified HMI programming. 24/7 Monitoring and controlling options because of IOT and VNC function.
