Wuppertal, 14 March 2023. The Schmersal Group and Wolf Verpackungsmaschinen GmbH will be jointly presenting an innovative packaging machine for the food industry for the first time at the Hannover Messe 2023 in Hall 09, Stand D09: The VPC-H 250 tubular bag machine has been specially developed for the packaging of confectionery and is equipped with the latest safety technology from Schmersal.
Gentle on the product and efficient – tubular bag machine from Wolf
The tubular bag machine is designed to package confectionery, cereals, snacks, frozen goods and sticks in bags made from thermoplastic films and laminated films in bag widths ranging from 50 to 250 mm. The VPC-H 250 is a high-performance machine with a low drop height, reaching speeds of up to 200 bags per minute.
A maximum of 100 programs can be installed for the machine’s PLC control system. Production parameters can be controlled using the colour touch panel. The machine works through the individual process steps, from feeding in the wrapping material to forming the bag, sealing the seams and filling, with high precision, whilst also going gentle on the product itself. Photoelectric cell control is used to ensure precise positioning of the printed wrapping material. Another benefit is machine handling, with convenience features including quick and easy format changes.
Innovative and hygienic – safety technology from Schmersal
The AZM300 solenoid interlock was installed on the compact VPC-H 250 machine, which requires only a small footprint. Solenoid interlocks are used to monitor the position of guard doors and to prevent the door from being opened until hazardous machine movements have ceased. Guard doors are also used on the VPC-H 250 to protect the safety of operating personnel.
The AZM300 RFID solenoid interlock from Schmersal is popular in the food and packaging industries because of its hygienic design and IP69 protection class. The AZM 300’s features include the patented operating principle with a hub and cross-head. It allows the guard door to be held virtually without play when closed. The RFID sensor enables maximum tamper protection in accordance with ISO 14119.
Emergency-stop buttons and illuminated pushbuttons from Schmersal’s new H series are used at the human-machine interface. The H series from Schmersal is a full range of command and signalling devices for hygiene-sensitive applications, particularly food processing. The new H series is consistent with the ‘hygienic design’ principle of design as well as the requirements of the new EN 1672-2 standard and Regulation 10/2011/EU. A total of 147 different devices are available, including 26 mushroom pushbuttons, 24 selector switches and four potentiometer-rotary switches.
The signals from the solenoid interlocks and emergency-stop devices are evaluated by the SRB-E-204-PE and SRB-E-322ST safety relay modules from Schmersal, which are both multifunctional and easy to configure and, with their slimline design, are easy to install in the retractable control cabinet of the VPC-H 250.
