| AD-4961 Series |
| Checkweighers |
|
|
| Best-in-class precision |
With a newly developed digital load cell and an ultra-high speed processing module, high level precision of 0.08g (3σ)*1 has been realized.
With this high accuracy checkweigher, you can minimize the giveaway of materials above the specified weight and contribute to reductions in production costs. |
| *1 For AD-4961-2KD-2035. Depends on the shape and the condition of the product and installation environment. |
| 7 inch color touch panel |
| The display utilizes a high visibility touch panel color LCD with user friendly Graphic User Interface (audio guidance support function included). |
| Image import from USB |
| Product images can be quickly uploaded to the checkweigher from a USB flash drive, making product identification and upload fast and simple. |
| IP65 |
| Protected from dust and water to IP65 standards. Hygienic design with the entire system washable. |
| Stores up to 1000 products |
| Products can be divided into 10 different groups, with up to 100 products able to be recorded within each group. |
| Lightweight and compact design |
| With its modular structure, the AD-4961 allows for rapid and simple installation or relocation. |
| Unique modular design |
AD-4961 consists of four units: an infeed conveyor unit, a weighing conveyor unit, a control unit and a base unit, allowing fast and simple assembly.
In the case of system shutdown, you do not need to wait for a service engineer to respond to the issue.
Just simply replace the unresponsive module by yourself, so that you can shorten system downtime and maximize production efficiency. |
| Optimization of weighing configuration |
By inputting throughput (products per minute) or belt speed (m/min), optimal weighing conditions can be automatically set.
You can weigh products precisely without inputting various settings. |
History function
Operational history
|
The history of configuration changes can be recorded and displayed. Suitable for use in HACCP programs along with the weighing history function.
Users can be registered and their scope of permitted operations controlled according to 4 management levels.
[ Operation ]
[ Supervisor ]
[ Quality Manager ]
[ Administrator ]
By assigning each user to the appropriate level of access, inadvertent operations can be avoided.*2
*2 "Operator" is set as the factory default setting. |
 |
Weighing history
|
Weighing results are automatically recorded in a USB flash drive during weighing.
Output data: Date, time, group and product number, weight data and judgments.
USB memory
Approx. 6MB memory size is required for 8 hours operation at the maximum throughput (320pcs/min.)
Approx. 7GB memory size is required for 24hours 365days operation. |
 |
| Modbus communication |
Equipped with Modbus RTU/Modbus TCP as standard.
With Modbus communication, seamless connection can be easily achieved.
Operations such as stopping and starting weighing, collecting data and changing product can all be set from an external device. |
| Various inputs / outputs |
Rejector output , alarm output, metal detector input, RS-232C, TCP/IP and USB interface are equipped as standards.
Storing data in a USB flash drive or outputting to a printer are also possible. |
| Graph printing to a printer |
| Histogram, X/R control charts and summary reports can be outputted to a PostScript printer via Ethernet. |
| Data summary |
Various summary data such as histograms (frequency including defects), X charts, R charts, total summaries, etc., are available.
You can visually confirm fluctuation of weighing results and adjust your manufacturing machine accordingly. |
Histogram, control charts and summary reports
After weighing, press the PDF key on the summary display. A PDF report is outputted to a USB flash drive.
The same reports can be printed out by pressing the PRINT key when a PostScript printer is connected to the checkweigher.

Summary results printing example  |
| USB memory function |
Weighing history and operation history are stored in a USB flash drive.
You can also output histogram, X/R control charts or summary data to a USB flash drive in PDF format.
A USB flash drive needs to be inserted before weighing. |
| *Please prepare a USB flash drive. |
