Definitions

  • the invention relates to a method for equalizing the density distribution in synthetic wood panels made from glued bulk material and a device for carrying out the method for producing synthetic wood panels with a floor conveyor bunker with discharge, the discharge width of which is the same as the spreading width for synthetic wood panels to be produced and devices downstream of the floor conveyor bunker for bringing down the discharged Bulk goods as an endless fleece on a forming belt.
  • the metering conveyor belt is infinitely variable and differently adjustable in height in the transverse direction below the stripping roller.
  • additional devices are not suitable, that is to say in the area where a bulk material veil is formed, different basis weights in the transverse direction of chip or fiber nonwovens, ie to uncover and remove synthetic wood panels. It is also not possible to determine the different density in the transverse direction on the metering conveyor belt.
  • the present invention is based on the object of proposing a method and a device for carrying out the method, detecting and eliminating density errors present in the bulk material as soon as it is discharged from a floor conveyor bunker and, if necessary, a density profile for to specify a finished synthetic wood panel when the bulk material is discharged from a belt conveyor.
  • This object is achieved with the characterizing features of method claim 1.).
  • the characterizing features of claim 3. With which a device for the production of synthetic wood panels is placed under protection, show, as by inventive arrangement of a measuring surface above a guiding surface, which is arranged between the bunker outlet and the further depositing devices for the bulk material, information about the instantaneous density distribution over the molded cross-section to be obtained, which, in conjunction with a density distribution specified for the finished synthetic sheet, determine a value which, as a control value, a separating device extending over the entire bulk width is too much for the decrease in the resulting density difference in individual areas over the cross-section scattered bulk material affected.
  • a further inventive embodiment of the measuring surface is protected, in which the measuring surface itself is designed according to the invention as a narrow plate which can be moved back and forth across the entire bulk width in front of the guide surface.
  • An embodiment of this movable narrow plate is that the arrangement for transverse movement of the plate also extends outside the dumping width, so that the entire device for maintenance and adjustment work can be removed from the dumping area without interrupting the pouring process .
  • the characterizing features of claim 6) provide a device for carrying out the method under protection, in which, in addition to compensating for the density profile, which would lead to a slightly lighter finished synthetic wood panel, this slight change in the weight of the finished synthetic wood panel compared to the predetermined synthetic wood panel by increasing the discharge of bulk material by increasing the belt speed.
  • the characterizing features of claim 7) protect the inventive use of a scraper belt which simultaneously serves as a discharge element, as a separating element and as a return transport element for the proportion of incorrectly discharged bulk material.
  • the outlet cross section of the floor belt hopper can also be provided with spiked rollers arranged one above the other, which extend over the entire width of the discharge cross section.
  • the discharge spiked roller closest to the floor conveyor then takes over the function of separation of the excess material and the return transport of it to the floor conveyor bunker in connection with a trough conveyor, which is designed as a spiral vibratory conveyor or screw conveyor.
  • inventive embodiments for the attachment of the measuring surface as a narrow plate are protected, in which the guarantee is given that contamination of the movable parts for receiving the movable narrow plate are excluded and also Care is taken to ensure that the bulk material itself does not hinder the measuring surface in its measuring activity, for example by pinching the bulk material between the guiding surface and the measuring surface when moving the measuring surface across the guiding surface.
  • a pole-changing motor which is acted upon by control commands or a direct current motor can be used to change the belt speed.
  • a scraper belt 4 covers the outlet cross section of the floor belt hopper. The scraper belt 4 rotates in the direction of the arrow and, in cooperation with a revolving floor belt 5, which closes the floor belt bunker downwards and whose speed can be adjusted, takes off a quantity of bulk material 6 that can be preselected for the production of chipboard from the front side.
  • This removed bulk material is fed to a scattering unit 7 and then brought down by this scattering unit 7 as a fleece 8 onto a forming belt 9.
  • the respective fleece weight is determined by a scale 11, whether as the total weight including the underlay or as a pure net nonwoven weight by subtracting the weight of the underlay .
  • a further spreader unit may be present in mirror image to the one shown while maintaining a floor conveyor bunker, or there may be two floor conveyor bunkers which feed the spreader units arranged in mirror image arrangement.
  • the scattering units shown which operate by means of the throwing principle, it is also possible to use scattering units which, by means of a blower, bring about a spreading good for the production of a nonwoven.
  • fan outlet openings arranged in mirror image can be used with a high throughput of fleece to be scattered, as is known, and combinations between scattering units based on the throwing principle and scattering units based on the wind scattering principle, as known, can also be used.
  • a measuring surface 12 is arranged between the floor belt bunker and the spreading unit 7, which is explained in more detail in connection with FIGS. 2 and 3c.
  • This measuring surface indicates the weight distribution of the pouring stream 13 in accordance with the bulk flow 13 conducted over it across the width of the spread s (cf. FIG. 3d).
  • a controller 14 to which a setpoint 15, which contains the total weight of the finished chipboard with a uniform density distribution, is simultaneously fed. From the different weight information of the bulk flow 13, which is a measure of the different density distribution in the particle board, compared to the constant information from the target value 15, a control variable that changes over the scattering range is obtained and is fed to an actuator 16.
  • This actuator is pressurized now tongues' of a separation device 18 in such a way 17 that the individual tongues protrude 17 through the spread width more or less corresponding to the distribution (see. Fig. 3d) in the bulk stream 13.
  • chips accumulate on the individual tongues, which are stripped off by the tongues 17 with the aid of the scraper belt 4 and over the returning run of the scraper belt 4 can be fed back to the feeder 2 of the floor belt bunker 1. It has proven to be advantageous if a guide plate 19 is provided over the total spreading width in the region of the deflection of the scratch 4.
  • the last scraper roller also has a guide plate 19 as a partial sheathing, to which a trough conveyor (not shown) is connected for returning the material to be returned to the belt bunker 1.
  • the trough conveyor can be provided with a screw or can be designed as a vibratory conveyor. The arrangement of a guide plate 19 thus prevents return material from falling back into the bulk flow 13.
  • the measuring surface shown in Fig. 2 has a narrow plate 22 which is arranged on a lever 23.
  • the lever 23 is supported on the one hand on a cross spring joint 24 and on the other hand is supported on a support rod 26 via a force measuring device 25.
  • the support rod 26 is mounted in a transverse guide 27 which extends over the entire spread.
  • a threaded nut 28 is also fixedly arranged on the support rod 26, as a result of which the narrow plate 22 can be moved transversely to the bulk width in cooperation with a threaded rod 29.
  • the distance a is selected according to the invention such that when the narrow plate 22 is moved, no part of the bulk flow can get stuck between the guide surface 31 and the narrow plate 22, so that there is no fear of the narrow plate failing.
  • the narrow plate still ends within the guide surface 31, so that the scattering unit 7 cannot be influenced by a non-uniform inflow of the bulk flow 13.
  • the housing 30 also carries a baffle plate 33 which, together with the guide surface 31, forms a slot along which the narrow plate 22 can be moved.
  • tongues 17 protrude into the stray current 13. In order to remove too much poured material as described in FIG. 1 and to feed it back to the belt conveyor bunker 1 together with the scraper 4 or with a scraper roller.
  • FIG 3a shows tongues 17 standing in the bulk stream 13 and a baffle 19 within the angle scraper 34, which absorb the material picked up by the tongues 17 by moving along the inside of the baffle 19 and, due to its angular configuration, does not drain back into the floor belt bunker.
  • a tongue 17 shows the tongue 17 in a roller bearing 35.
  • the tongue 17 has at its rear end 36 a threaded bore 37 which cooperates with a threaded pin 38.
  • the setscrew 38 is mounted in a guide 39 and is adjusted by an adjustment drive 40, in the simplest case as a drill chuck, on its threaded head 41 by turning the adjustment drive 40 to the right or left for its region of the pouring stream 13 into or out of the pouring stream .
  • the guide 39 can be supported as a cross-member extending to the left and right of the bulk width over the entire bulk width.
  • the adjustment drive 40 moves from tongue 17 to tongue 17 transversely to the stray current 13 and adjusts each individual tongue according to the information received from the controller.
  • the measuring surface 12 shown in FIG. 3c consists of a plurality of plates 42, the individual widths b1 to b of which are selected according to the requirements. If, for example, measurements in the finished particle board have determined that the greatest density fluctuations occur at the edge of this plate, it will be advisable to provide small widths b there.
  • the individual plates 42 are provided with strain gauges 43 and thus enable the measurement of the respective weight distribution over a certain partial width of the entire bulk width. This results in the weight distribution image shown in FIG. 3d over the scattering width s without a narrow plate having to be moved over the guide surface 31.
  • the tongues 17 are formed in their width corresponding to the plates 42, so that a direct to there is a relationship between the measured instantaneous distribution and the quantity to be purchased.
