In 1992, in CEVISAMA, TALLERES FORO S.A., presented a prototype then known as COMPUTERIZED GLAZING LINE and which was the germ of our present work. The concepts then exposed, have been discussed up to nowadays in talks, congresses, round tables and so on, and in close contact with the technicians of the sector, we arrived to the conclusion that the positive values which fall directly upon the production are:

Repetitivity>> Versatility>> Capacity of analysis.

These three concepts define our present INTEGRATED GLAZING LINE. To achieve it, the works realised over the machines which compose it and over the own control system, have been intense and reason for big human and economic investments, but they have allowed that in these moments, the total of our machines to be capable of being installed with the norms and advantages which convey the integration; that is to say, they can be communicated with the control system.

This fact allows the change of parameters or factors relative to the proper functioning of each machine, with simplicity and efficiency, allowing the work by formulae, which help to the repetitivity of the product.

TECHNICAL ADVANTAGES

1. It facilitates the maintenance labours by means of helps where the mechanical characteristics of the elements of the glazing line are indicated.

2. It allows to realise reports regarding to production data in a personalised and definitive way.

3. Alarms list. All the alarms, which provoke the proper system, are reflected in historics’ shape (starting and stoppage, communication errors with the PLC’s or any other anomaly of the proper system).

4. 4. It makes possible the realisation of changes in the parameters of the machine in the following ways:
...A. A. Over each one of the elements in the place where it is placed (at the bottom of the machine).
...B. Over each one of the elements communicated from the PC having access to the associated date to the mentioned component.
In this task there are included the variators as well as the PLC’s which compose the communications’ line.
...C. From the formulae pages where you can accede to the speed parameters (frequency variators), as well as compensers, silk-screen printing machines, flow regulator, or any other element which has PLC and which it is connected in the communications’ glazing line.
The communications’ sense in all cases is bi-directional, that is to say, when we realise a variation in a parameter to the foot of the machine, we can load it from the PC, being part of the formula, to which we will give a name, which will serve us to launch it to the machine and to change all or part of its parameters in an automatic way.

5. The inlets and outlets of the bedside PLC are placed through all the machine in modules shape AND/OR situated in the boards of the variators in the way that allows to use the inlets or outlets available in each one of them for purposes related with the operation or data taking (distributed periphery).

6. It offers the possibility of having access to other programs:
-Management of PLC’S.
-MS Excel.
-MS Word.
-Management of inverters.

7. Weighing machine. It allows the data taking relative to weight, density, viscosity, besides the code of the technician, which realises the measurement having them available in historics’ shape.

8. Optical pyrometer. It realises a continuous register of the temperature of the pieces in historics’ shape.

9. It allows the insertion of any other type of datum for being an open system.

10.It allows the traffic density control of communications and other inherent data to the own system.

11.Because it is an INTEGRATED GLAZING LINE, it allows its location as an another element for the control of an integral management of the plant.
