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 .
