Random rotary placers are used in a variety of applications ranging from placing labels on passing product, to dropping product into a case on passing conveyor. Random rotary placers can be used to solve both random in-feed and constant feed applications. This application controls the rotary axis of the placer to insure accurate placement as well as providing management of the placing mechanism.
Application Challenges
- Random Product In-feed
Controller must be able to account for product being fed at unpredictable intervals and realign to place product in the correct location.
- Increased throughput
Higher productivity should result from the addition of this motion control solution due to higher speeds and lower downtime
- Smooth Motion
The solution must yield smooth motion to reduce machine wear produced by jerky accelerations, resulting in increased machine life and lower maintenance (more uptime).
- Matching Conveyor Speed
As product is being placed, speed matching is critical to insure precise location for applications such as a label placer.
- Product Selection from Magazine
Controller must discern and anticipate when to pick a product from the magazine so that product is only grabbed if material is being fed down conveyor.

Application Details
Utilizing electronic camming coupled with precise cam profiles and on-the-fly cam shifting technology, Yaskawa motion controllers handle both random in-feed and constant pitch feed conveyors to place your product right on the mark. The Yaskawa solution utilizes profiled position based control rather than speed control in order to provide guaranteed accuracy even during fluctuating conveyor speed.
Incorporating the Yaskawa line of Sigma II amplifiers and servomotors introduces the highest quality servo equipment in the industry to increase performance and reduce downtime. In addition, Yaskawa motion controllers can be integrated into larger control systems using Yaskawa machine controllers as well as a variety of communication capabilities, to provide ultimate connectivity and complete Yaskawa solutions.
