The LBC100 has been designed to detect unglued, delaminated, blown or low density areas, bubbles, cracks and other ﬂaws inside any type of board (PB, MDF, OSB and Plywood).
Unlike earlier systems that had a limited number of measuring channels and i.e. 12,14 or 16 channels etc, and hence covering a minimum percentage of the board, the LBC100 can mount as many as 54 channels with a 75 mm resolution. It is possible to grade the quality of the production in progress and to adjust the product parameter to avoid rejects and maximize customer satisfaction.
The system is composed of a sturdy aluminium beam, installed around the conveyor, complete with the electrical and pneumatic plant. It may be installed in combination with the Winthick thickness gauging system on the same beam.
The full bond/blister classiﬁer LBC measuring sensors are mounted on the top and bottom beams on the board outfeed side. Since the sensors do not come into direct contact with the board, typical problems related to material wear are eliminated. The automatic calibration and dirt accumulation control ensure an efﬁcient and highly reliable measuring control system.
The operator interface for setting up the plant parameters and those for the single productions is simple and straightforward to use and the formulas may be stored and retrieved at a later date. The display can be customised by choosing from the numerous high resolution 3D colour graphs available.
Numerical indications are also given. The parameters are stored in an SQL database and can be used to display and/or print reports on the desired productions, based on user determined choice criteria (date of production, shift, production name). The microprocessor is equipped with a digital oscilloscope which is seen on the monitor and which displays the ultrasound transmission and receiver signals one by one when the need arises. In addition to being user friendly and extremely intuitive to consent a prompt and immediate interpretation of the data collected, the software also provides detailed diagnostic screen pages to enable maintenance operators or Imal engineers carrying out remote assistance, to perform a full diagnosis of the equipment. A powerful microcontroller is mounted inside the receiver to transmit the data for the signal measured, to the CPU via Data Bus. The system may be network connected with TCP/IP protocols, for Siemens S7 and Allen-Bradley ControlLogix.
