Protection of a handling machine in cheese manufacturing

To protect a handling machine against moisture, a C2000 Safety Light Grid with an IP67enclosure rating has been installed.

At a French Camembert factory, employees often work near hazardous areas such as stack collectors. Since hands and fingers are most susceptible to injury, a reliable safety solution that doesn’t interfere with the production process is required. At an ambient temperature of 77° F, the safety system has an atmospheric humidity of up to 85 percent. The machine must be washed off once or twice a day using alkaline or acidic cleaning agents. Cold water (41 to 50° F) at a pressure of 40 psi is also used for rinsing and cleaning.

The compact design and PMMA acrylic tube housing of the SICK C2000 Safety Light Grid is ideal for use in this harsh environment. The protective housing was designed without trap points for dirt or contamination. A pressure equalization membrane integrated into one of the end caps prevents the penetration of moisture and ensures condensation does not form on the window. The cable entry is provided using proven PG cable glands.

The resistance of the materials used for the IP 67 housing series and the cable was positively assessed in material compatibility tests performed by Ecolab (Henkel) for the cleaning products P 3 (P3-topax 56, P3-topax 66, P3-topax 91, P3-topactive 200, P3-topactive DES). The low pressure foam method (COP cleaning and disinfection) for the food processing industry is recommended.

The C2000 Safety Light Grid is an electro-sensitive protective equipment of Type 2 in accordance with IEC 61496. The parallel light beams generate a flat protective field in front of the dangerous area. Any Unauthorized or inadvertent movement within the running machine by an employee results in the interruption of one or more light beams. The evaluation electronics for the C2000 detect this situation within a few milliseconds and immediately generate a shutdown signal for the stack collector.

Using the C2000 Safety Light Grid in an IP 67 housing ensures reliable protection despite harsh ambient conditions. The machine protection meets not only the requirements in relation to hygiene, resistance to cleaning, availability, and safety, but also the requirements in relation to ergonomics and productivity, as the stack collector is always accessible when shutdown.

Cascading Mini Twin Safety Light Curtains Provide Safe Packaging Operation

Protection from a manual loading station in a cartoning machine by cascading 3 miniature safety light curtains in U-shape.

The French company ARIES PACKAGING develops and builds full automated solutions for handling of products as well as solutions for secondary and tertiary packaging.  Aries developed a cartoning machine with ergonomics as top priority, i.e., easy access for the machine operators. To guarantee the packaging quality the packages are transported by a gear belt with a cadence of 30 cartons/mm and with a transverse speed of 2 m/s. Taking into account the risk of injuring hands caused by the pusher of the belt, it was essential to integrate a protection system with high resolution to ensure the total safety of the operators.

Simplified safety mechanisms on a packing machine

The “V300 Extended” camera safety system monitors guard doors while securing assembly cell areas at the same time from “reaching over” and, together with a photoelectric sensor, can provide exit only protection on a wrap around tray packaging machine.

Challenge
A wrap around tray packing machine takes 6 or 12 drink cartons and puts them onto tray cutouts. The machine folds up the sides of each cutout and glues it to make a tray, which now provides a secure base to transport the goods. Several guard doors have to be monitored so that the machine stops if a person reaches in. The output of the machine also represents an access point to dangerous movements. One particular requirement is to safeguard the machine with electro-sensitive protective equipment which is quick and easy to install and which reacts within a specified time to an operator inserting their hand.

Application Solution
This requirement can be quickly and easily met with a “V300 Extended” camera safety system and a photoelectric sensor. This is electro-sensitive protective equipment based on image processing technology. The sensor sender and receiver are integrated in a single housing, as are the additional reset and EDM functions (Electronic Device Monitoring) to check the protection provided). To monitor the nine guard doors, the “V300 Extended” is installed in the upper right hand corner and the reflective tape is fitted to the fencing and also over the door frames. Taking account of the machine stop time, this means that the cell height can be reduced by more than half. The consequences of this include easier access, reduced safety costs, simple installation and maintenance as well as higher productivity.

Benefit
During the initial installation, or for realignment of the “V300 Extended”, there is no need at all for the time-consuming alignment of sender and receiver which would otherwise be necessary. The camera safety system is also well protected by being installed in a corner. With just a single device, several guard doors can be secured at the same time.
