OPUS1Series

The Ultimate Servo Feeder

The Variax OPUS1 series is a high-performance servo feeder that is optimal for use in motor core production lines for hybrid, PHEV, and EV car motors. By integrating a high capacity servo motor and roll into one body, it achieves world-class performance. The driving servomotor is operated according to a unique cam curve. Servomotor and cam curves are also used to control vertical roll motion and the release mechanism, allowing the OPUS series to feed thin and soft materials. The controller in the OPUS series is equipped with a large monitor and diagnostic functions. It offers IoT preventive maintenance and diagnosis, as well as good operability.

VR Series

Servo Feeder for Heavy-duty Applications.

The concept of this servo feeder is simplicity. Both upper and lower rolls are servo driven, and operate when a start signal is input from the press controls. Driven upper and lower rolls provide precision and power for a variety of heavy materials. Feed materials with up to 3.2-mm thickness. Applications include motor core stamping and metal bearing stamping. Extremely flexible adjustments allow various handling possibilities, such as irregularly shaped material and long feed pitches. These features make the VR Servo Feeder ideal for mid and low-speed press stamping applications. Also featured is an easy-to-use touchscreen interface and hand-held controller for improved operability and reduced setup times.

VR Series (1 Model)
| VR250 |

►Variax Catalog [PDF:5.9MB]

【Features】

►Directly driven main rolls deliver consistent feed accuracy.

►Features a choice of roll materials, shapes, and adjustable roll positioning to best suit the material to be fed

►Suitable for a wide range of workpieces, including motor cores, metal bearings, and connectors.

►Performs a pre-programmed feed operation when a timing signal is input from the press controls to allow use with non-crankshaft type presses (such as servo presses).

VG Series

Fine feed with a soft touch. Reliable, high-speed gripper gives good results.

This unit feeds materials by gripping them. The combination of four cam mechanisms provides high speed, high precision, and high reliability. Unlike roll feeders that feed materials by rotating the rollers, a gripper feed uses the coefficient of friction to grip materials. Therefore, a gripper feed makes it possible to feeding materials with different shapes and also soft materials. It will not create pressure scars or flaws on materials, feeds in fine increments if desired and can feed at super-high speed. It can also be used as a secondary processing feed. Various types of gripper feeders are available to match your feeding conditions.

【Features】

►Various types of models are available to match your feeding conditions.

►Available feed up to 3,600 min-1 ultra fast.(VG15H)
►Combination of the gripper and the clamper is suitable for secondary processing and Materials with different shapes.

VGX Series

New type grip feed with adjustable release timing using a handle.

To make adjustments without tools, to make fine adjustments during operation, to supply material at creep speeds, the new cam-driven grip feed is exactly what you want. It was developed from the results and experience we have established to improve work safety and operate at high speed. In addition to the excellent features (high-speed, high-precision feeding, and hard to scarred materials) of the VG series, this series lets you adjust for material thickness, feed length, and release timing without needing any tools. Also, fine adjustments can be made during operation. These adjustments can be made with handles (or pushbuttons on the VGX350), and the current settings are displayed by mechanical counters, so that adjustment is truly easy. A grip parameter system is used to adjust the material thickness and gripping force, which means that parameter adjustments can be done simply and precisely, compared with existing models. By improving the usability of the VG series, the VGX series are complete, high-functionality products that can handle a variety of material feed conditions. They have the features and advantages listed below.

VGX Series (4 Models)
| VGX30 | VGX60 | VGX100 | VGX350 |

►Variax Catalog [PDF:5.9MB]

【Features】

►Improved adjustment functions (added adjustment functions that use handles to set material thickness and the release position)

►Improved applicability for different material shapes and secondary processing of materials.

►When the material thickness setting is changed, the upper material guide does not need to be adjusted.

►By employing a gate-shaped gripping clamp arm, the material gripping force is improved and the feeding capacity is improved.
