Centrifugal Feeders

The steady and problem free emitter supply of our feeders is a key element of their design. Especially for high speed production lines like our N350 FL that runs constantly at 350 meters per minute (m/min) and requires a capacity of 2.500 Nano emitters per minute (e/min).

Flat emitters need to be placed with their outlet chamber facing upwards before entering the inserting unit, in order to be in the correct place for the drilling machine to make the hole or cut in the right spot. Furthermore, non-symmetrical emitters like Nano, have to be placed in a certain direction, since the outlet chamber is at the edge of the emitter and not at the center.

This need, along with the increased speed and inserting rate of the N350 FL, led us to develop an entire new and innovative way of handling the emitter's direction. This is achieved by a unique statistical motion analysis of the emitter that our R&D department has developed. The result is higher percentage of sorted emitters inside the centrifugal feeder and a steady insertion rate.

The build quality of our feeders is extremely important since they handle an enormous number of emitters during their lifecycle. Our feeders are manufactured with extremely precise machinery and the highest possible quality materials, selected for the particular operation. Special chemical treatment of all the aluminum parts, ensure a life-time and trouble-free operation.

The feeders are designed and manufactured by keeping in mind another important aspect related to the production floor, which is the overall space occupancy of the production line. Being able to achieve top performance and durability by keeping the feeder as small as possible is challenging yet achievable with the correct design.

The use of a centrifugal feeding system in combination with the extremely low manufacturing tolerances of the parts, results in a non-damaging feeding and insertion process of the emitters. Each feeder carries individual alarm signaling, with both visual and acoustic functions for distant alarm acknowledge. The alarm can be set for several different parameters including lack of emitters, emitter jam, a subsystem malfunction etc. All individual alarms of the feeder unit can be set and accessed through the main control panel.

The feeder incorporates a fully automated self-cleaning mechanism for the unlikely event of emitter jamming. The entire process is a combination of a specially developed software, along with the mechanical design and characteristics of the feeder. This combination ensures the perfect balance between the pre-feeder and the inserting unit. The feeder acts as a balance connection point of the overall feeding unit, between the emitter storage which is the pre-feeder and emitter destination, the inserting unit.
