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. VG50 Various types of models are available to match your feeding conditions. Available feed up to 3,0 ultra fast.(vg15h) Combination of the gripper and the clamper is suitable for secondary processing and Materials with different shapes.

VGX series ew 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. 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.

VUC series Offers high-speed, good follow-up control, and stable material feeding. Our original loop controller is suitable for high-speed feed lines. This uncoiler was designed to create a stable material feed for this loop controller. It works at high speed and has good follow-up control. The rotating section that winds and unwinds coils of material is driven by a servomotor, so that the feeder supplies the correct amount of material to match the press rotation speed in real time. Also, by installing a movable arm in contact with the outer surface of the coil, the radius can be determined and therefore the amount of material left can be controlled, offering remarkable stability while feeding.

Drive units V.S.D. (Variax Servo Drive system) The servo drive system is excellent for synchronized performance. The VSD (Variax Servo Drive) was developed specifically to drive cam feed units with servomotors. In order to achieve compliance with the start/stop characteristics of a press, our proprietary, newly-developed controller has integrated into the system to offer excellent synchronized performance. And, since the feed timing and indexing angle can be easily changed, it is being installed on more and more Variax products. Installed the VSD on a VGX series model. S.C.T. (Self-Compensating Tensioning drives) This simple drive system stays synchronized with the crankshaft even if the pass line is changed. The S.C.T. drive is an input drive system. It was developed to reduce the work involved in installing or adjusting a drive used as an input for Variax products synchronized with the motion of the press crankshaft. Since it consists of a parallel crank mechanism, the synchronization between the crankshaft and feed unit input axis never changes, even when their relative positions change. Since the feed unit slides up and down when aligning the feed path height, the rotation timing with the press does not change and the synchronization can be maintained. Related products VGT Twin gripper feed Optimum for feeding wide materials This is a breakthrough twin gripper feed model. By holding wide materials securely with two grippers, one on each edge, this feeder can be just as precise as our other models. Using this method, the feed length, material thickness, and gripping force can be adjusted independently so that a precision straight feed can be achieved, which is simply not possible with a conventional roller driving system. The level of orthogonal feeding, relative to the metal die, can be improved dramatically. Indexing unit for rotary lamination process This is Cam Index-drive for rotary lamination motor core. It has V.S.D. for driving system. V.S.D has highly synchronized performance and providing simplify synchronization with press system. Cam - Servo Motor hybrid system provide high speed and high accuracy performance and easy operation. Furthermore, the skew motion model is also available.
