Embodiment Construction

[0041] figure 1 A device 1 for determining the strength of a wood fiber insulation board is shown. The wood fiber insulation panels 2 are transported on a conveyor device 6 . The conveying device 6 is, for example, a conveyor belt 15 . The partial view shown is in a plant for the manufacture of wood fiber insulation boards in the conveying direction F downstream of the continuous press for the raw material spread on the forming belt and the saw for cutting the wood fiber insulation boards to final dimensions for sale cutting device upstream. The upstream press and downstream cutting table are not shown in the figure for clarity. But the basic manufacturing process technician of wood fiber insulation board is known by DE102008039720B4. Additionally, as in Figure 4 Shown in the schematic top view of , downstream of the continuous press 18 is a device 1 for determining the compressive strength, after which the wood fiber insulation panels are cut into rectangular individual...

Abstract

The invention relates to a method for determining the strength of a wood fiber insulation board. A contact element (3) is pressed on a local region of the wood fiber insulation board (2) through a pressure, the compression of the wood fiber insulation board (2) is generated in a predetermined stroke, and the pressure is determined at at least one compression point. According to the method, the contact element is arranged on the wood fiber insulation board (2) above a conveying device for the wood fiber insulation board at a downstream of a continuous press, the contact element (3) is pressed into the wood fiber insulation board (2) through an actuator (8) at a thickness of 1%-7% of the thickness of the wood fiber insulation board, the required force or the required pressure therefor is determined through at least one force measuring sensor (10), data of the force or the pressure and stroke data are transmitted to a central calculator (12) for extrapolation of a standard compression stroke and the theoretically required pressure thereof.

Description

technical field [0001] The invention relates to a method for determining the strength of a wood-fiber insulation board by pressing a contact element onto a local area of ​​the wood-fiber insulation board by means of pressure, compressing the wood-fiber insulation board over a predetermined stroke and at least one compression Click to determine the pressure. [0002] The invention also relates to a device for carrying out the method. Background technique [0003] The strength values ​​that determine the quality of wood fiber insulation boards are usually determined by carrying out destructive material tests on samples taken from ongoing production. Compressive strength is an important quality feature in wood fiber insulation panels. For this purpose, for example, a square slice with a dimension of 100 mm x 100 mm is loaded at a defined speed with an indenter which has a relatively large base area. To do this record the pressure-compression travel graph. [0004] The curve...
