Safety system design limits installation
downtime
The important deciding factor for a tyre factory in updating its safety systems on rubber caldender machine was the limited amount of downtime needed to convert the old safety system.
The Cooper Tire and Rubber Company Europe Limited manufactures Avon brand tyres and are recognised as a world leader in the pneumatic tyre market The business evolved in 1885 and it was during 1890 the company relocated to Melksham in Wiltshire, England

Safety PLC gives machine builders more flexibility
Safety PLC offers more flexibility to machine builders when designing safety systems and provides a high level of safety according to category 4, EN954-1.
Connect many devices on same safety circuit
A cost effective solution makes it possible to connect many types of safety devices on the same safety circuit and still achieve category 4 according to EN 954-1.
Light curtains and grids offer reduced costs
Latest range of light curtains and grids have the inputs and software already in the curtain, which reduces costs for wiring time and for bypass controllers.
By 1901 the company expanded due to the increase of its tyre production business and has been in the automotive market since.
Engineers at the company had the task of updating the safety system on a Rubber Calender machine built in the 1960's.
The system comprised of two Vital safety control units monitoring a combined total of 40 safety devices to Category 4 EN954-1.
The devices were an arrangement of various existing safety components such as footswitches, emergency stop pushbuttons, grab wire switches and limit switches.
Jokab Safety non contact Eden switches were used to replace conventional switches where mechanical switches were found to have a reduced service life.
Where other manufacturer's existing products were being used, the Jokab Safety Tina interfaces made it a quick and easy transition for devices to be incorporated on to the Vital Solution.
A spokesman for Cooper Tires said that they searched the market to find a safety system that would fulfil their strict requirements.
One such requirement was the need to have local indication and feedback to the PLC of the safety device status.
The important deciding factor for choosing Jokab Safety was the limited amount of downtime needed to convert the old safety system to the Vital Solution.
This was achieved during the Christmas holiday period.
The machine has been operational 24h/day, 7 days/week since, in order to meet the demand for their products.
The installation engineers were impressed with the modular aspects of Jokab Safety's unique system.
The ability to 'daisy chain' safety devices, have indication of where a fault occurs both locally and remote in the circuit, and still meet category 4 EN954-1 were key points.
The installation met with all of the engineers expectations and as a result Cooper Tire and Rubber have already invested in a second Vital System.
