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.

Sick Solution Helps Traceability and Safety Demands for SHL’s Auto-injector Assembly Machine

Tracking and tracing material numbers using a 2D code reader, preventing damages and injuries via safety light curtains and safety locking devices and controlling quality in limited mounting space with compact and precise sensors in an auto-injector assembly machine.

Challenge
The SHL Group is the world’s largest privately-owned designer, developer and manufacturer of advanced drug delivery devices, including pen-injectors, auto-injectors and inhaler systems. It consists of three distinct group companies: SHL Medical, SHL Healthcare and SHL Technologies. Limited mounting space, traceability and safety requirements have led SHL to look for a supplier able to provide a solution for these challenges. Usually SHL uses fiber optic sensors in assembly-testing machines. However, due to a specific request of one of its customers to use compact sensors instead of fiber optic sensors, SHL identified SICK as a supplier able to provide a compact sensor that fits its applications. One requirement was a sensor with a precise light spot able to detect a transparent glass syringe tube. Additionally, a miniature 2D code reader was needed to trace material numbers. Lastly, to prevent damage to its machines and prevent an operator getting injured, SHL required a safety light curtain and safety locking devices for doors.

Application
For traceability, SHL identified, in close cooperation with SICK, the image-based code reader (ICR803) as an ideal solution for handling the tracing requirement. The code reader perfectly fits into the limited space SHL has available for mounting. To fulfill the requirement of having compact optic sensors that were precise and easy to align, SHL relied upon SICK’s proximity sensor with PinPoint technology (WTB4 PinPoint) with a clear, visible red light spot and SICK’s laser proximity sensor (WT9L) with a very precise light spot able to detect small parts inside the syringes. Additionally, both SICK sensors provided a perfect price-performance ratio. The safety light curtain (C2000) and the safety locking device (i10 Lock) from SICK provided machine and operator safety. SICK‘s ability to provide various solutions and sensor expertise has met the customers’ needs as a partner for total sensor solutions.

Protection of a punching machine

One safety light curtain protects an automatic punching machine and at the same time increases the machine performance by approx. 30 % in PSDI mode.

On a punching machine for labels, brochures, credit cards, children’s books and savings books, protection must be provided against people reaching into the running machine with its sharp knives and punching pressures of 5.7 metric tons. This protection is to be designed such that the operation of the machine is not hindered.

Application Solution
The punching machine is equipped with a C4000 Standard safety light curtain with a protective field height of 300 mm and 14 mm resolution. The signals from the light curtain are evaluated in the UE402 switching amplifier.

Benefit
Using the C4000 electro-sensitive light curtain, safety according to type 4 is achieved together with significant production advantages. The direct access to the machine when it is not in operation saves a considerable amount of time and shortens the machine’s cycle time. It was possible to increase the machine’s productivity by up to 30%; depending on the item punched.

Safe Stack Turners and Logistics Systems in the Printing Industry

Modular safety system exploits rationalization potential

Due to increased printing capacity, automation of logistics processes is critical. Printed sheets must arrive at the feeder and be delivered without process delays. With every unnecessary machine stop, the printing and ink parameters must be reset and optimized, adding time, waste, and cost to the process.

Application Solution:
All operator-accessible points on the machine are monitored with light barriers and light grids. Pepperl Fuchs SLA29 sensors are permanently active safety light barriers. Their detection range is extended by means of adjustable mirrors as far as this is useful. Depending on the risk potential, SLC30 safety light curtains may be required as an option for hand protection.

Benefit:
Previously, Krifft & Zipsner had used four different switching devices by two manufacturers for every machine, for example, the SLVA-4K evaluation device for the permanent light barriers and the SLVA-8K for the muted light barriers. All of these functions are now performed by the Safebox in an easier and more rational way.
