Electric Panels

The design and construction of electric panel supports the specialisation in software application development. Our electric panels meet automatically commanded devices with modern integrated solutions in compliance with international and environmental standards.


Application: Abrasion limitation on fabric

Traction controlled synchronisation using a reel for rope bleaching and dyeing machines. The scope of this development is to obtain greater movement control, being able to set the speed and torque of the three-phase, asynchronised motor, applied to movement of a winch traditionally installed on any machine for rope dyeing. The device thereby solves winch speed synchronisation problems with the actual speed of the fabric transported. Wrong synchronisation often causes abrasion. The fear of such abrasion and streaking that can occur on the fabric means the speed has to be reduced and
therefore the possible load on the machine used. Traditional systems stop fabric movement on total stoppage, or on registering a change in cycle time set, thereby working with a delay.Use of our “hardware&software” applications gives considerable advantages and enhancements, often completely eliminating the problem.


Application: Automation and upgrading movement control in an
electrical axis for Jigger

Upgrading the atmospheric and pressurised jigger by replacing the
now dated hydraulic control units with modern movement control systems on an electrical axis. Huge advantages are obtained from this “revisitation” because investments are limited in the
purchase of new machinery, since the upgraded machinery can finally be made competitive using the new systems.
Electrical axis control can be implemented both with feedback control of the loading cell and without using it, replacing it with an advanced software application implemented on the drives that control the motors and the programming unit.
The tensioning precision and speed allow work to be carried out on fabric with excellent results in terms of quality and production.
Automation is completed with total management of all the other functions, such as filling, unloading, washing, dosed insertions and the heat cycle.
The just modified machines can be connected to the centralised SI-DyeTECH system which from remote allows planning of the work set-up, intervention on the work in progress, interfacing with other services to the dye-works (Dosage systems, ERP,.. ),
adjustment of processes, the analysis of production costs and dialogue with the production progress systems.


Application: measurement of the pH value for continuous and discontinuous machinery even at high temperature (130°C) and active correction of the value measured.

The system can be installed for display only of the pH measurement data or with the automatic compensation unit of the value according to the settings entered on the program that adjust the process on the machine.  The application can be made both for atmospheric machines and for pressurised machines up to 4Bar and a temperature of 135°C.
The pH reading sensor in real time provides the signal measured on the controller that guides the automatic process.
When the system is complete with active compensation and adjustment of the pH, the controller will give the command to
inject an acidic or basic reagent so the pH reaches the desired value.
Integration is such that it is possible to interpolate the pH curve, controlling it together with other curves that adjust the treatment or dyeing process.
The control system design takes into consideration the application field typically found on machinery subjected to hard work cycles in difficult environments and up to temperatures of 140°C.; for this reason, installation includes a series of controls and
actions so that the electrodes used are kept clean and efficient throughout the duration of the life cycle to always use them with utmost precision.


Application: automation of a dyeing padder and dye dissolution.

This application overall controls a “Pad_Batch” dyeing plant,using technology which, on the one hand,meets the need to work with different staff who are not particularly expert,without
encountering substantial differences in operating the process; on the other hand, insertion is ensured of a similar work process, in the context of a modern, automated and computerised dyehouse.
Siemens electronic equipment was chosen for this reason: “touch screen” series panels capable of managing multiple processes at once to enable simultaneous management of the two Dissolution and Dyeing functionalities. The programs saved in the equipment enable adaptation to the requisites of the dyes used both in terms of
temperature and mixing.
The operator chooses from the programs available and indicates the final volume together with the weight of the dye to dissolve.
These data, and much more, can also be entered by reading a unique barcode on the dye recipe, avoiding any typing, or by receiving data from production planning. Each command is also possible in manual mode.
There are different level measurement devices to avoid the density of the liquid or foam altering in some way the necessary volume measurement.
The “Padder” joint takes place using a mixing collector. The wide range of level and temperature parameters
allow you to avoid or register any malfunctions.
The temperature of the dye, the alkalis and their mixing in the “padder” is monitored. The program also manages cooling of padder containment via a cooling unit, displaying the temperature present.
Detection of the metres worked allows correlation with the volume of dye present and defines the residual autonomy in metres of fabric.
Having reached complete dyeing, the program will automatically clean the Padder cylinders, the piping used and the dosage pump.
The times and temperatures are managed by the program to cool the piping and after washing to avoid damaging subsequent dyeing.
Ample care was taken to make registration possible of what took
place during the work, to allow interaction with industrial planning.
