Definitions
- the invention relates to a method for detecting process parameters in the production of wood-based products, in particular wood-based panels, which are hot-pressed with the application of pressure and heat and a wood-based product as such.
- Wood-based products for example OSB boards, chipboards, MDF or HDF boards, can be produced in different ways.
- continuous pressing processes with heated press belts may be provided to strip the beaches provided with adhesives, such as glue, glue or resins.
- adhesives such as glue, glue or resins.
- Both the short-cycle presses and the so-called Kontipresen compress the chips or fiber cake or the scattered fibers, chips or strands and activate by the heated press plates or press belts, the adhesives, so that the strands, chips or fibers enter into a permanent bond to each other.
- the production process of such wood-based material products is subject to a multiplicity of parameters, for example the spreading density, moisture of the starting material, gluing factor or uniformity of the scattering behavior or the orientation of the starting materials, so that the knowledge of process parameters, for optimal performance of the hot pressing of wood-based materials for the production of wood-based products, how temperature, pressure and humidity is important within the wood-based products.
- the data is present in order to intervene regulate.
- measuring devices into the material to be pressed and to press, wherein these measuring devices are wired and connected to an evaluation unit.
- These meters are very large and can not be used in the current production process, without interrupting it.
- these measuring devices must be removed again after pressing the wood-based products, whereby the wood-based products are no longer usable.
- the removal of the measuring equipment is expensive and usually destroys the wood-based product.
- the production process for removing the meter must be interrupted.
- the inventive method for detecting process parameters in the production of wood-based products, especially of wood-based panels, which are hot pressed under application of pressure and heat provides that in the current manufacturing process at least one measuring device for detecting pressure, temperature and / or moisture is introduced into the unpressed starting material and remains in the final product and that the measured process parameters are read out wirelessly.
- at least one measuring device for detecting pressure, temperature and / or moisture is introduced into the unpressed starting material and remains in the final product and that the measured process parameters are read out wirelessly.
- the measuring instruments are miniaturized on the basis of the available methods of microelectronics and micromechanics such that they can be left in the product on the one hand without affecting the product quality and on the other hand are available inexpensively in sufficient quantities, so that no removal of the instruments from the finished products for economic reasons is required.
- the measuring device can store the process parameters so that a change in the process parameters can be tracked over a time course.
- the measuring device is designed so that the
- the wood-based product in particular the wood-based panel, which is made of hot-pressed wood materials, provides that a measuring device is incorporated in the wood-based product, wherein the measuring device transmits the process parameters wirelessly to an external readout unit.
- the measuring device can be designed as a "transducer” or can be equipped with an active, independently transmitting transmitting unit in order to transmit the process parameters or measured data, which were determined during the hot pressing process, to an external readout unit immediate transmission of the data must be made to the evaluation or readout unit.
- Figure 2 an embedded measuring device during activation
- Figure 3 - a hot pressing process
- FIG. 1 shows a first stage of the production of a wood-based product, here a wood-based panel, in which a first layer or layer of glued chips, strands or fibers 2 is sprinkled on a lower press panel 1.
- the strands, chips or fibers may also be made as a mixture thereof.
- a measuring device 3 in the form of a miniaturized measuring sensor is placed or interspersed, which is able to determine the relevant process parameters such as pressure, temperature and humidity and, if necessary, to record.
- the pressure and possibly the moisture within the wood-based product 6 can be detected and read at a later time, so that a state detection and determination of the wood-based product 6 in its use is possible.
