1/ What Is Servo Zigzag Feeder
Servo zigzag feeder can minimize the edges and corners material produced in stamping production by means of back and forth zigzag shifting feeding way, to ensure circular with circular mutual cutting blanking, to improve production efficiency, it also improve material utilization ratio. This type of feeder is mainly used for wafer and square metal blanking production, because it has high efficiency and high material utilization rate etc. advantage, the zigzag feeder is now more and more chased by customers.
2/ Structure of Servo Zigzag Feeder
The structure of the zigzag feeder is composed of three main structures: working machine frame, feeding machine head and electronic control box.
- There are two parallel linear guideways in left and right directions of settings on the working machine frame, and ball screw rods is set at the center of the two guideways, to parallel with the two guideways, there are left and right movable frames is set on the guide rail, and screw sleeves under the left and right movable frames, the screw sleeves are matched with the threads of the ball screw rods.
- left and right movable frame has two parallel axes of left and right parallel, the parallel axle is perpendicular to the guide rail of the frame, the parallel axle is fixed in the left and right movable frame, a screw is set up between two parallel axes, two parallel axles are equipped with front and rear movable frames, the lower part of the front and rear movable frame is provided with a screw sleeve, which matches the screw threads of the left and right movable frame, the screw sleeves are matched with the screw threads of the left and right movable frames.
- A servo motor is added to drive the screw and ball screw in the engine frame, and the servo motor is connected with the control box through the signal line.
3/ How Does Zigzag Feeder Works
When constant Henli zigzag feeder and punch are matched to use together, After setting up the program in the control box, the servo motor of the punch feeder drives the ball screw to drag the left and right movable frame, the material is pushed to punch to start stamping from left to right, When the material is stamped from left to right, the servo motor drives the screw on the left and right movable frame to move forward and backward, then the servo motor drives the ball screw to push the left and right movable frames back from right to left, and the second row of the material starts stamping again, so as to realize the circular with circular mutual tangent stamping production, which greatly improves the utilization rate of materials.
4/ Advantages of Servo Zigzag Feeder：
- Simple operation, high degree of automation, it only needs to input the width of the material, the diameter of the required blanking circular and the feeding step on the touch screen, the control system can automatically calculate the distance between movement and feeding, it doesn’t need to adjust any mechanical mechanism, to realize fully automatic operation and use.
- Two-way shifting alternating feeding, high productivity and cost-saving, it can ensure that circular with circular mutual tangent punching blanking, to maximize use the materials, save production costs, the operating system can automatically calculate the layout angle according to the size of the product wafer diameter, to ensure that raw materials are saved.
- The blanking accuracy is high, because it uses one Mitsubishi PLC to control two sets of Yukawa servo motors, a set of servo motor system is connected with the feeding drum by synchronous pulley to realize the precise control of the feeding drum, the other set of servo motor system is connected with the silver precision roller screw rod in Taiwan by synchronous pulley, to accomplish precise left-right movement, in the process of continuous stamping, the small distance between edge and edge can be set within 0.5mm,and the feeding error can be controlled within+0.08mm,to meet the higher and higher processing requirements.
High speed servo zigzag feeder has become one of the most commonly used feeders in many enterprises nowadays, the reason why zigzag feeder can be chosen by the enterprises is that its unique feeding mode of left-right back-and-forth zigzag shifting, not only can it minimize the edge materials in stamping production, but also it can improve the production efficiency, and at the same time it also improved the material utilization rate, to create higher benefits for enterprises, it is especially suitable for the blanking production line of wafers and square metals.
