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.
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.
