Feedback control by weighing result |
Application Example
Final Inspection of Packaged Boxes
- Can be used as the final inspection step in your production line by checking whether some items in a box are missing by weighing the box.
- Many logistics centers and production plants for food, cosmetics, machine parts industry, etc., adopt a checkweigher in their final inspection phase.
|
|
| Feedback Control by Weighing Result |
- Weighing results can be fed back to another system upstream of the production line.
*Image below is an example of feedback to a filling machine. |
 |
| Advantages |
| Easy Operation |
- Operated by a 7-inch color touchscreen.
GUI on the touchscreen makes it very easy to understand and operate.
- Up to 1,000 products can be registered and categorized into 10 different groups.
An image of each product can also be quickly and easily registered from a USB flash drive.
- Configuring settings is very simple.
|
 |
 |
|
 |
| Connectable to Barcode Reader |
- AD-4942B can be connected to a barcode reader (*) in the same processing line.
By reading the barcode on a product, the product settings are automatically switched to those of the scanned product. |
 |
| *Barcode reader shall be prepared by the customer. |
Data Management
- Weighing data can be automatically summarized and can be output to a USB flash drive as a PDF file.
- The data is helpful for management of HACCP.
- AD-4942B can automatically record Weighing History and Operational History.
The records can be displayed on the touchscreen and can be output to a USB flash drive as csv files.
- AD-4942B can display and output checkweighing summary data and X/R control charts.
X Control Chart shows average values and R Control Chart shows the gap between maximum and minimum values.
- Operational History shows a record of the changes made to the settings and is also helpful for management of HACCP.
- To operate the device, user name and user level are registered.
For each user registered, you can limit the operations they can perform depending on their user level.
Inadvertent operation can be avoided by assigning each user a user level from the four levels below.
| Various Communication Methods |
- AD-4942B has various interfaces: RS-232C, RS-485, a USB flash drive, LAN cable, wireless LAN, etc.
- AD-4942B can communicate with devices supported by Modbus without a program through serial communication and/or TCP/IP communication.
|
 |
| (Machines/devices that communicate via Control I/O is connected via a relay board in the weighing unit.) |
| Wireless LAN |
- Weighing data can be checked on tablets, smartphones, laptops, etc., via Wireless LAN.
*Wireless LAN can be used depending on the regulations in your region.
*Wireless LAN receiving sensitivity depends on the radio wave environment.
Caution is required when performing continuous monitoring. |
 |
| *The above is an example from a different model, but the format is the same as the AD-4942B series. |
| Remote Maintenance |
- Touchscreen can be operated from a PC via a LAN cable connection using device operation software for PC.
- By utilizing remote control software to control another PC, the touchscreen can be operated from another PC.
- This is useful for remote maintenance since engineers can check machine settings even if the AD-4942B is in a remote place.
(Please prepare separately, a LAN cable, PCs, device operation software for PC and remote-control software.) |
 |
| Selectable Weighing modes (Automatic operation) |
- Passing weighing:
Weighing without stopping conveyor while product is passed along the conveyor.
- Stop weighing:
Weighing with stopping conveyor after the detected product enters the conveyor.
- Static weighing:
Weighing with stopping conveyor after detected product enters the conveyor and is in a stable state. |
