Comparison between traditional textile electronic control system and VC600C series control system

VC600C is developed based on VEICHI's strong R&D and production capabilities, adopts a breakthrough integrated design concept, has stronger protection, higher integration, longer service life, solves many problems of traditional electronic control, and comprehensively improves water jet loom control level.

4 major defects of traditional electiccontrol cabinet

1. The protection grade of the cabinet is low, and the fan will bring the on-site steam and oil vapor into the cabinet, which will not only cause faults such as short circuit of the components in the cabinet, but also seriously reduce the service life of the equipment.
2. There are many wires and the wiring is messy, which is not only prone to interference, but also increases the fault easily.
3. The adjustment method of weft detection is complicated and backward, and the efficiency is very low. We need to open the chassis for each adjustment.
4. The volume of internal devices is large, which restricts future functional expansion.

VC600C Cabinet Introduction

The IP54 protection level of the box(certification:20210505K12013), effectively isolates the steam and oil vapor on the weaving site,ensures the normal operation of the equipment,and improves the service life of the equipment;the whole workshop can be powered off for a long time during holidays.

Fanless design 

Solve the problems that the fan of the traditional textile control cabinet is easy to be damaged caused by water, oil accumulation and other problems, and prolong the life of the electronic control equipment.

LED indicator 

The running status of the loom is clear at a glance, making maintenance more targeted.

Back radiator 

The air duct is designed on the back of the box, and the temperature in the cabinet is effectively reduced through the back radiator and the using life is improved.

Small size and high integration 

The VC600C series directly eliminates the cost of the equipment manufacturer's chassis, is smaller in size, lighter in weight, and more convenient to install.

Visual weft detection(invention patent number: ZL2019 10889295.5)

The self-developed visual weft detection technology improves the traditional adjustment method of weft detection, and the adjustment of weft detection is more intuitive and faster; it has the self-learning function of weft detection, which can effectively prevent empty stops and missed stops.

VC600C series cabinet layout introduction 

VC600C all-in-one machine relies on VEICHI's rich product lines, and adopts advanced modular design concept in the cabinet, which has a more reasonable layout, more convenient maintenance and stronger extensibility.

1. Easy maintenance: Just replace the corresponding control board.
2. More scalable: Equipment transformation, upgrade, only need to adjust the corresponding control panel.
3. Eliminate the wiring between units: Solve the problem of poor contact of wiring in high vibration environment.
4. Standard terminalless toroidal transformer: Lower temperature rise, no afraid of vibration, more stable operation.
5. Adopt common DC bus technology: Compared with traditional asynchronous motors and direct drives, it is more energy-saving.

Support process parameter copy: Machine parameter settings, process settings, parking gear compensation settings, etc. can be copied to another system with a USB flash drive, which is convenient and quick to set once.

Introduction of VC600C series weft insertion control and digital weft detection 

The problem of weft detection has always been a difficult problem for end customers. In order to solve this problem, VEICHI has adopted the dual weft detection technology of outer detection and inner detection on VC600C through years of painstaking research and development to escort the stable operation of the equipment.

1. Built-in digital weft detection technology, real-time display of weft detection waveform.
2. The sensitivity of each jetting weft yarn is independently set to solve the empty stop or the non-stop wefting caused by the large difference of the multi jet weft yarn.
3. External visual weft detection to solve the problem of difficult adjustment.
4. Support high-end weaving needs of four jets.
5. The real-time tracking adjustment algorithm of the main shaft is built in the pattern board, and the weft insertion control is more stable(magnetic needle, rotary valve, yarn gripper, etc.).

VC600C series built-in electronic dobby control introduction

1. The main control integrates electronic dobby control, supporting 16 pieces of brown frame.
2. The timing angle of the electronic dobby is controlled by the host encoder, which is more accurate than the original proximity switch control, and completely avoids the phenomenon of wrong flowers. 
3. It supports pattern editing with 10,000 steps or more, supports the weave cycle of the fabric, supports empty beating-up, stop prying, and freely change the weft density.
4. It provides dual pattern editing environment on HMI and PC, and supports arbitrary switching, reading and storage of local master control and U disk.

Introduction of VC600C series electronic let-off and take-up function

Electronic let-off and take-up system controlled by integrated main system

1. The main control integrates the advanced discrete tension PID control algorithm to make the tension converge quickly.
2. Supports 10,000-step pattern variable weft density settings, and the weft density of each shuttle can be freely and steplessly changed.
3. Supports rich functions such as left and right double warp beams, upper and lower double warp beams, and tension control of outof-machine winding.
4. Combined with the weave cycle of the fabric, the tension fluctuation under the complex weave pattern is within a reasonable range, and the hidden gear (for unbalanced weaving) is eliminated.
5. Built-in weaving fell swing, weaving fell avoidance, skid stop, weft compensation, time compensation and other new functions.
6. Rich maintenance navigation, the oscilloscope displays the tension curve and the let-off and take-up speed curve, which makes the human-computer interaction more in-depth.
