High repeatability checkweighing by optimizing checkweighing settings

The optimum checkweighing settings are automatically set when the weight and length of weighed products, and throughput or conveyor belt speed are input. Setting for vibration elimination filter (HPDF) is also automatically selected. So, checkweighing can be performed easily regardless of the operator.

Waterproof structure: IP65 Stainless steel cover for display unit is available as an option.

Equipped with a 7-inch color touchscreen and a new CPU, operability has been improved and AD-4961A series are easier to use. AD-4961A series have high visibility and operability, and even first-time users can easily set up the system. By registering and displaying a photo of the weighed product, a user can immediately check what product is being produced. 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. The standard display unit is made of a reasonably priced, waterproof resin. If preferred, a stainless steel cover is also available as an option.

USB interface as standard specification USB interface is in the control box when the Stainless Steel Cover is mounted.

Automatic switching of product settings by reading barcode

By reading the barcode on a product, the product settings on the Checkweigher are automatically switched to those of the scanned product. *2 *2 Barcode reader shall be prepared by the customer.

Wireless LAN as standard feature enables remote monitoring.

Wireless LAN function is equipped as a standard feature. *3 *4 Various data such as Summary Data can be monitored on tablets, etc., in another room, even during weighing. *3 The standard wireless LAN is for monitoring only and cannot be used for remote operation. *4 Wireless LAN can be used depending on the regulations in your region.

Also, remote maintenance is available.

You can operate a Checkweigher from a PC by connecting it to a PC. In addition, the AD-4961A can be used for offsite maintenance by "remotely operating *5" a PC connected to the AD-4961A via wired LAN from another PC in a remote location via an Internet connection. *5 In addition to the AD-4961A, other necessary equipment such as a PC and an Internet connection must be provided by the customer.

User management

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.

Data summary

Various summary data such as histograms (frequency including defects), X-Bar Control Chart, R Control Chart, total summaries, etc., are available. You can visually confirm fluctuation of weighing results and adjust your manufacturing machine accordingly.

History function

Weighing results can be automatically recorded in a USB flash drive during weighing. Output data: Date, time, number, product number, weight data, preset tare and judgment. [USB flash drive] Approx. 8 MB memory size is required for 8 hours operation at the maximum throughput (320 pcs/min.) Approx. 8 GB memory size is required for 24 hours 365 days operation. Operational History shows a record of the changes made to the settings. The Operation History as well as Weighing History can be saved onto a USB flash drive. Weighing History and Operation History are helpful for management of HACCP.

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.

*10 Reception sensitivity of wireless LAN depends on radio wave environment.
      For continuous monitoring, it is recommended to use a combination of the HMI indicator and the Modbus communication function
      via RS-485 or wired LAN as communication may be interrupted.
*11 Wireless LAN can be used depending on the regulations in your region.
*12 An Internet connection and a system for remote operation are required. Please consult with your sales staff for further detail.
*13 USB flash drive should be formatted in FAT32.
*14 Maximum number of input/output points that can be added will depend on the combination of additional input/output points.
