Crosland VK - supplying and fitting Sick laser scanners to ensure total safety in hand-fed platen operation

Over a period of many years, hand-fed platens have occasionally caused serious or fatal injuries to operators of these machines. These incidents occurred when operators reached into the machine whilst it was in the 'dwell' mode - under which circumstances, power to the hand-fed platen was not isolated and the safety devices fitted to the machine did not prevent the platens from closing.

In response to the problem, the Health and Safety Executive (HSE) recently issued a Safety Alert drawing this serious matter to the attention of firms in the printing and cardboard packaging industries. The Safety Alert makes numerous proposals, including 'suitable procedures....(which)... may include isolation and lock-off of the power supply or other equally effective measures before the operator attempts to gain access onto the hand-fed platen.' The Safety Alert also lists a number of European Standards to which new machines purchased after 2005 should conform.

Fortunately, an excellent solution has now been provided by Crosland VK, the world's largest independent manufacturer and supplier of hand-fed platens and automatic cutting/creasing machinery. Involving a laser scanner for the hand-fed platen and conforming to the proposals contained in the recent Safety Alert from the HSE, Crosland VK can supply and fit a laser scanner (manufactured by the international firm of Sick) to your hand-fed platens, ensuring that the machines will operate safely in the 'dwell' mode.

Operating under these circumstances, Sick laser scanners fitted by Crosland VK provide non-contact monitoring of a freely programmable area. The Sick laser scanner for the hand-fed platen requires no separate reflectors, and installation is simple because the sender and receiver are accommodated in a single housing. The Sick laser scanner is mounted above the hand-fed platen, and sends out a signal which covers the entire cutting plate area. The beam is 350mm above the cutting plate of the hand-fed platen, allowing the operator to feed the machine easily when in 'dwell' mode. The Crosland VK system fitted to the laser scanner for the hand-fed platen is very unobtrusive and can quickly be installed in one day by our skilled and experienced engineers. The unit is sealed and cannot be by-passed - and in the highly unlikely event of a problem, it will always fail to 'safety' mode and stop the machine from running.

The laser scanners supplied by Crosland VK are sourced from Sick, a world leader in sensor technology. Sick laser scanners and Sick's industrial application solutions ensure reliable and efficient control of processes in order to protect operatives from accidents, and for preventing environmental damage.
