Oy M. Haloila Ab is a world-leading manufacturer of pallet wrapping machines and is part of the international Signode Industrial Group. The most well-known brand from the Finnish company is the “Octopus” packaging machine.
This modular pallet wrapping machine is the first packaging machine in the world to have a rotating ring construction for flexible adaptation to customer requirements with regard to production capacity, transport protection, and stability.
Bluetooth wireless systems from Phoenix Contact are the reliable and wear-free solution for communication between the central controller and rotating machine parts.
The pallets are placed in the wrapping machine by means of conveying technology. A wrapping ring moves around the pallet and wraps it in film. The film is then heat-sealed and the pallet is taken away.
In order to control the pallet wrapping machine, data must be exchanged between the controller in the central control cabinet on the machine and the actuators in the rotating machine parts. Communication takes place via PROFINET or EtherNet/IP™. The previous transmission method via collector wire reaches its limits with Ethernet.
In place of a collector wire, an Industrial Bluetooth communication solution from Phoenix Contact is used to guarantee reliable, wear-free communication between the central controller and moving machine parts.
The Bluetooth EPA modules have been specially developed for the communication of control data. The robust modules feature protection class IP65 and are suitable for use in harsh industrial environments. Equipped with a special integrated antenna, the system also wirelessly transmits automation protocols such as PROFINET and EtherNet/IP™ easily and reliably.
Bluetooth is the chosen wireless technology in this case, as the frequency hopping method and WLAN channel blacklisting guarantee fault-free parallel operation with the existing WLAN networks in the 2.4 GHz frequency band.
Thanks to the Industrial Bluetooth solution from Phoenix Contact, machine reliability has increased and significantly less maintenance is now required according to Janne Koskela, Technical Manager at Haloila.
“The previous layout of the Octopus machines severely restricted data transmission between the actuators of the control system and the actuators in the moving parts. The wireless solution has opened up more options and increased reliability. We are extremely happy, both with the products and with Phoenix Contact's commitment and support”, says Koskela.
The FL BT EPA Bluetooth module has also impressed with its easy startup. Based on the positive experience with the advanced, wear-free solution, the FL BT EPA module is now integrated into all packaging machines in the Octopus series according to Janne Koskela.
