The TV604 COIL (Control Objectification Integration Line) system was designed and built by SOFCA s.r.l. to control and monitor the tightening of the VISAᴿ clamps produced by CAILLAU.
The system is able to check the proper tightening, count the number of clamps that make up the assembly cycle, check that the assembly sequence was properly followed, control that the right clamps were used on the applications and transfer the data to a storage system based on the use of a PLC, PC, or ETHERNET.

Through the self-learning tutorial function, the system is capable of determining the range of values related to the control of the tightening, so that the technician can analyze and correct if necessary.

The VISAᴿ and VISAᴿE closure is activated by a hydraulic tool, the Straight Cylinder, which is an integral part of the SOFCA COIL system. On the handle of this unit is the command button to close the clamp and on the back end of the unit is a light ring which indicates the outcome of the operation according to the computation of the COIL system.

The C.O.I.L. system gives the best guarantee on the VISAᴿ clamp tightness by applying the following strategies:

  • Step by step tutorial for setting up: the self-learning function of the system automatically works out the optimized values of the tightening parameters
  • Detection of set parameters values is in real time, during the tightening process, by reading the sensors
  • Data processing and decision based on the outcome of the tightening
  • Graphic display of the tightening cycle is viewed on the Control Unit. Light indicator on both the control unit and the Straight Cylinder, print out of the results, release of the data on PLC / external PC or remotely via Ethernet
  • Scheduled Maintenance by setting the limit values for the replacement of the 'nose' and / or the 'knife' of the Straight Cylinder; the alarm for the need for maintenance set in the Control Unit will warn the operator.

The Control Unit also allows programing up to 30 different programs for the setting of the control parameters and tightening cycles; programs can be selected via barcode and are supported by the system automatically.

Sofca can supply the COIL system assembled as an "operating station" and configured according to the customer's needs.
