Checkweigher

Maximum throughput of 1,000 products/min

Anritsu Checkweigher AW9 Series Ultra-Fast Type is the culmination of over 50 years of development in dynamic weighing technology. It incorporates a number of new technologies, including a new force balance scale, digitalization of scale signals, and a high-rigidity center-balance layout. As a result, the equipment achieves a maximum weighing throughput of 1,000 products per minute. It is compatible with ultra-fast packaging lines for light-weight products, which were previously difficult to handle.

New Digital Force Balance Scale

With further improvements to the performance of the scale, it achieves a maximum weighing accuracy of ±0.006 g even at high-speed weighing.

Advanced vibration control technology

As production speeds increase, the vibration of the conveyor has a greater impact on weighing accuracy. Therefore, it is essential to have technology to control (eliminate) the effects of vibration. The vibration characteristics vary depending on the size of the weighing conveyor, but in the past, only a single control was possible. However, in the AW9 Series, precise control is now possible to match the individual vibration characteristics of each weighing conveyor by digitalizing the control. This realizes high-speed and high-precision weighing.

Vibration-resistant frame structure and center balance layout

Vibration is a major obstacle to accurate weighing. However, in production lines, scales are always subjected to vibration from surrounding machines and their own conveyor vibrations. To address this, Anritsu has developed a new frame structure based on detailed simulations. The frame itself has been significantly strengthened over previous models, and the scale is mounted on an independent base to physically isolate it from the vibration source. This minimizes the effects of vibration and maximizes the performance of the scale.

Dedicated air-blast rejector

The AW9 Series Ultra-Fast Type comes standard with a dedicated high-speed air-blast rejector that enables accurate rejection even at 1,000 ppm. By detecting the position of the product at a stable stage after it has been transferred to the rejection conveyor, the sensor compensates for the rejection timing, ensuring accurate rejection.
