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.
3. If you have any technical problem, please contact us.

Brief Introduction of SDVC34 Variable Frequency Vibratory Feeder Controller

Introduction

The SDVC34 controller is designed for controlling the Bowl Feeder, Linear Vibrator.

1. This controller can search the resonant frequency of bowl feeder and linear vibrator automatically by vibration sensor.
2. There are two ON/OFF digital control terminal of the controller to cycle turn the feeder bowl ON or OFF, and you could connect the switch sensor or PLC digital output port or PLC relay port to the terminal. 
3. You could adjust all the parameters of the controller by RS485 communication, it can support ASCII/RTU Modbus protocol. 
4. The controller will stop its power output to protect itself and the load, when the output current exceeds rated value.

Note

1. I will continue to update the article about how to use controller.

The Default Setting Restoration Operation of SDVS30 series Intelligent Optical Feeding Parts Sorting Controller

Introduction

The SDVS30 series controller designed for sorting the feeding parts in Automatic vibrating feeding system. Sometimes, you maybe not sure which of the parameters has changed so that the controller can't work following your expectation, and you could use the Default Settings Restoration function to set all the parameters to the default value.

The operation of the Default Settings Restoration function as shown in the video:

Note

1. The above operation only takes the parameter group A as an example.
2. Each parameter group of A, B, C, D has its own reset function that "Default Setting Restoration".
3. The reset operation of parameter group B is similar to the parameter group A , and press the Set Button and Up Button for 2 seconds to enter the parameter group A setting interface and press the Switch Button to enter the parameter group B interface.
4. The reset operation of parameter group C, D are similar to the parameter group A, B.

Our new product SDVS30 series controllers sort feeding parts by optical feature of parts

Introduction

In automatic vibrating feeding system, you will encounter the situation that feeding workpiece has the same shape so that the feeding device can not sort it by shape. If the workpiece has different optical features itself, the SDVS30 series controller can sort the feeding parts based on its surface reflective property. The controller is so intelligent that you only need set it with simply operation steps. The following takes the sorting material as an example to introduce the operation steps of the controller.

The scene of sorting feeding parts with SDVS30 as follows:

Description of controller

The SDVS30 control panel as follows:

Figure 1: control panel of controller

The SDVS30 upper panel as follows:

Figure 2: upper panel of controller

The SDVS30 below panel as follows:

Figure 3: below panel of controller

Installation

You only need provide the compressed air which pressure not exceeds 5 Bar for the controller, and the air input tube installation as follows:

 Figure 4: installation of air input tube

The output air tube for blowing the parts, and its installation as follows:

 Figure 5: installation of air output tube

The installation of optical fiber sensor as follows:

Figure 6: installation of optical fiber sensor

Our SDVC series controller can power to the SDVS30 controller, and the wiring method as follows:

Figure 7:  wiring method of power supply for SDVS30

Sorting feeding parts video

This video include all the above operation steps of setting controller for sorting feeding parts and the effect of sorting feeding parts.

Note

1. The SDVS30 series controllers include two types controller : one (Type: SDVS301) has single optical fiber sensor and another (Type: SDVS30) has dual optical fiber sensor .
2. This controller can solve much problem in feeding system, please pay attention to the follow-up articles.

The "Preset Speed" help you using two digital signal to switch feeder speed that you could preset

INTRODUCTION

In the process of the auto-manufacturing, engineer need to switch between different speeds according to different materials. For convenience and easy adjustment, presetting the feeder speeds which will be remembered by the controller,  when the materials is changed, use two digital signal to Switch the corresponding speed that remembered.
I will show you how to use the "Preset Speed" function that switching the feeder speeds using two digital signal.

 READY

You need to prepare a vibratory feeder controller (Product Type: SDVC20S), 15 Pin Plug, two self-locked switch and some wires, As follows:

Figure 1: Vibratory feeder controller (Product Type: SDVC20S)

Figure 2: 15 Pin Plug 

Figure 3: two switches

THE METHOD OF WIRING

The schematic and physical diagram of wiring to the controller are as follows：

Figure 4: Schematic diagram of switch wiring

Figure 5: Physical diagram of switch wiring

The video 1 show you how to wire the switch to controller:

Video 1: wring the switch to the controller

PRESET SPEED

The "Preset speed" can switch between four speeds and the speed is decided by the combined state of two digital signals. when switch A or switch B signal is valid, The speed A or B indicator will be Correspondingly light up, as follows table 1:

Speed	The state of Speed A Indicator and Speed B Indicator	Default Output Voltage "H"
Speed 1	Speed A  Indicator:  Dark Speed B  Indicator:  Dark	150
Speed 2	Speed A  Indicator:  Dark Speed B  Indicator:  Light	160
Speed 3	Speed A  Indicator:  Light Speed B  Indicator:  Dark	170
Speed 4	Speed A  Indicator:  Light Speed B  Indicator:  Light	180

Note: you could find the output voltage "H" LED symbol on the panel of the controller.

The video 2 show you in details how to adjust the presetting speed, as follows:

Video 2: feeder speed adjustment

Note: The adjusting speed will be remembered by the controller automatically. 

The video 3 show you in details how to switch between four speeds which have preset in the video 2, as follows :

Video 3: switching between four preset speeds

NOTE

1. The type of switch A and switch B can be NPN sensor, self-lock switch, Relay or other NPN signal.
2. The type of controller including the "Preset Speed" function are SDVC20-L, SDVC22-S, SDVC21-S, SDVC34 Series, SDVC41-M.
3. If the preset speeds over four speeds, you could use the "Remote speed" function, please click here :The "Remote speed " help you to solve the trouble that manually adjusting the feeder speed
4. Each of our products have this "Preset Speed" function.
