Introduction of SDVC20 variable voltage vibratory feeder controller

Introduction 

This series controller can remote the feeder speed by potentiometer, so as to make the controller positioned away from the control panel. The internal digital voltage regulation circuit can reduce feeder speed changes caused by Input power voltage fluctuation. The output waveform is sinusoidal which controlled by bidirectional thyristor. There are two output frequency can be output, one is the same as input power frequency and the other is double input power frequency. For example, if the input power frequency is 60Hz, the output frequency are 60Hz and 120Hz separately.

Function

1. Adjustable Soft Start Timer: the controller will smoothly increase output voltage from 0 to the preset value when the power on to avoid the feeder bowl shake.
2. Preset Speed (Feed Speed store and recall): 4 feed speeds can be preset, remote to change the feed speed by combination of two switch or PLC signals.
3. Remote Speed Control: Power output voltage of the controller can be adjusted remotely by an external potentiometer, a 1-5V DC signals of PLC or other 1-5V DC signals.
4. 24V DC output control: The controller can output 24V DC voltage follow the ON/OFF power output of controller to drive a relay switch or other external devices.
5. Dual switch sensor ON/OFF power output: 2 NPN switch sensors or PLC's relay can be conected to turn on/off the power output of controller.

Keep the correct parts level in the bowl by SDVC34 vibratory feeder controller without parts level sensor

Introduction

In some case, the automatic feeding system include hopper, feeder bowel, in line feeder and  robot arm. when the feeder bowl is empty or below the parts level which you expect in the bowl, you need to feed it manually or automatically from hopper. Most situation you should use the parts level sensor to see whether the bowel is empty or not, but our controller can help you to achieve it without level sensor and the level expected can be adjusted by parameter in the controller. In addition when the feeder bowel is empty or below the level that you expect, the controller will give a 24V DC signal that could enable the alarm light bulb, the hopper or other automatic devices.

The principle of detecting the parts level

The controller can stabilize automatically the feeder speed by vibration sensor. when the amount of parts in the bowel is decrease, the power output voltage will be decreased for keeping the constant feeder speed, so we can know the parts level in the bowl by the power output voltage.

Figure1: automatic feeder system

The threshold value, the lowest parts level in the feeder bowel, can be adjusted by the parameter "GL" in the controller. 

Process of keeping the correct parts level

The video will show the process of the feeder automatically.

Searching the resonant frequency of the feeder bowl by SDVC34 controller

Introduction

When you use vibratory feeder controller to drive the electromagnetic vibrator, you need often search the resonant frequency of the vibrator manually for the well working amplitude.  In some situation, the resonant frequency of the vibrator may be changed and some controllers can't follow the changing frequency automatically, so we designed a controller which can search the resonant frequency of the vibrator automatically. when the resonant frequency of the vibrator changed, the controller can change the output frequency of the controller automatically all time for matching the changing frequency of the vibrator. 

Using method of the controller

1.Fixing the vibration sensor

2.Entering the automatic resonant frequency search function

 Press the "🔺" button and "🔻" button simultaneously and hold for two seconds           for entering the Searching  resonant frequency function.

3.Searching the resonant frequency is successful 

 when the display screen show the "SAVE", the controller have found the resonant frequency of the vibrator successfully.

4.The video of automatic search resonant frequency as follow:

Note

1. This controller can track the resonant frequency of the vibrator in real time.
2. when you connect the vibration sensor to the controller and no operation in  ten seconds, the controller can enter the Automatic Resonant Frequency Search function automatically instead of pressing  "🔺" and "🔻" buttons.
