CN Teledoor Teamwork Again with Cannon & Manni
TELEDOOR ISOLIERTECHNIK GMBH IN MELLE, GERMANY, IS A FAMILY-OWNED COMPANY THAT SINCE 30 YEARS DEVELOPS, PRODUCES AND DISTRIBUTES“ CUSTOM-MADE COLD STORAGE CELLS” AND EVERYTHING THAT IS RELATED WITH THEIR FUNCTION, ALWAYS TAKING MAXIMUM CARE FOR THE QUALITY AND R E L I A B I L I T Y O F T H E I R G O O D S. TO EXPAND THEIR PRODUCTION PLANT A NEW AUTOMATIC CANNON-MANNI FOAMING LINE WILL BE INSTALLED THIS YEAR.
In 2008 Cannon already supplied Teledoor with a complete foaming line with a polymerisation press: the positive experience made with it was a good starting point for a new project, started in 2015. Cannon was asked again to quote, design and produce an automatic production-line according to the needs of its customer. Cannon Deutschland de ined, together with the owners of Teledoor, Eckard and Veit Bowenkamp, the priorities for one of the most innovative solutions available on the market.
Multi-daylight Presses, a Cannon Manni Speciality Polyurethane, as insulation media, again appears as an ideal partner for the manufacturing industry: any change in design and dimension of the products can be handled by easily adjusting some production parameters at the dosing unit. It is a well-known fact that the thickness of foam determines the demoulding time of the panel, which is directly proportional to the longer polymerisation time. To optimise the production cycles, two manufacturing concepts are wellproven for discontinuous panels: the use of shuttle presses and a multi-daylight design. Cannon and Manni – a long-time Cannon-Partner for the development and production of discontinuous panel production systems – were the irst manufacturers of Polyurethane equipment who presented the optimal multi-daylight press design. Since the beginning of their cooperation, more than 30 years ago, the development of new innovative solutions and the supply of larger and larger plants have never stopped. The multi-daylight press with individual opening technology, in combination with the use of the Cannon JL mixing head, is now setting new standards in the fully automated production of sandwich elements, according to the high standards required by the German market.
A Dedicated Solution for Teledoor The new Teledoor production line is composed by the following main components:
· Multi-Daylight Press with 10 independently operating daylights: 11 press platens, automatic loading and unloading system, fully automatic mixing head manipulator tri-axial, mounted at the longer side of press, automatic laser-guided system for a reliable detection of the injection holes, mezzanine platform for the entire wet part and all the hydraulic aggregates.
· 3-component High-pressure Foaming Machine, Cannon A-System 200 Servo- Penta Basic: Dosing machine output up to 3,000 g / s. Mixing head Cannon JL 26, for automatic injection at the longer side of the press, premix station for Polyol + Pentane, type PEF 40 + 4, safety control for Pentane emissions, including IR sensors and ventilation.
Independently Operating Daylights Several workstations have been integrated for the preassembly of the panels on special service trays and included in a tray-transfer system. A pneumatic loading system takes over the trays with mounted supports and foaming tools and passes them to the 10-daylights press. The press concept allows for the independent opening of the single daylights, so it is possible to simultaneously produce different panel thicknesses without the passive periods due to the longer polymerisation times of the thicker ones. After the automatic opening of the relevant cavity the tray with a foamed panel is extracted from the press and lowered to working height level. During this process new trays are simultaneously inserted and the daylight is closing. The new range of panels has been designed and produced by Teledoor according to the long experience matured in the cold stores business: their d e s i g n r e q u i r e d s p e c i a l t e c h n i c a l speci ications to the new press, and the teamwork between Teledoor, Manni and Cannon again worked perfectly.
3-component Foaming Machine With a Smart Mixing Head The wet part of the entire line, designed for the use of Pentane as blowing agent, can dose three chemical components. The premix unit automatically doses Pentane and Polyol according to the desired recipe. The resulting batch is supplied to the tanks of the high pressure dosing machine, a Cannon A-System 200 Servo- Penta Basic, equipped with a Cannon JL 26 mixing head. The injection of the reacting blend can be carried out in different injection holes, with the possibility to perform several injections in quick sequence. The fully automatic mixing head manipulator can be positioned precisely on three axes. The integrated laser system checks availability, position and dimension of the injection holes and grants permission for the introduction of the mixing head. The JL 26 mixing head is a self-cleaning, L-shaped high-pressure version, whose entire foaming cycle is fully automatic, without the need of inal purging of the mixing chambers with air or solvents. In addition to numerous advantages in terms of foam quality and even distribution of material within the whole volume of the panel, the JL 26 mixing head features a self-cleaning 370 mm long nose: introducing the mixing head in the side pro iles of the moulds to reach the cavity of the panels is a straightforward operation.
A State-of-the-Art Control The whole production process is controlled by a PLC of the latest generation, a SIEMENS S 7 – 1500, that handles the press operations with a status of master over the whole plant. The foaming machine is equipped with a SIEMENS control of the same series, which dialogues with the master PLC. All data for production is transmitted by means of barcodes to the master control of the multi-daylight press, for a completely automated and error-free process. As interface to operator( MMI) a Siemens Touch Screen Operator Panel 21,5“ is used. The on-board diagnostics-system makes debugging easier and a maintenance program allows to schedule important tasks routinely.
A Successful cooperation The plant will be operative by the end of 2016. Installation and start-up phase will be fully executed by Cannon Deutschland Technical staff. The Teleservice assistance provided in real-time by the German arm of the Cannon Group ensures that the high standard of the supplied equipment can be exploited by Teledoor with maximum productivity, minimum downtime and an optimised consumption of chemical raw materials.
The press concept allows for the independent opening of the single daylights, to optimise the polimerisation time of each size of panels.
