Definitions

  • the invention relates to a method for producing material plates with a continuously operating press according to the preamble of claim 1 and to a system for carrying out the method according to the preamble of claim 14.
  • the pressing force is transmitted by hydraulic actuators on the press and heating plates and further on steel belts, which are supported by a rolling element carpet (rolling rods) circumferentially arranged on the pressed material.
  • the steel strips with thicknesses of approximately 1.5 to 4 mm form the weakest component in the chain of failure-threatening machine elements compared to the other, substantially stiffer elements. In this context, it does not mean that the steel strip fails completely, but should the surface of the steel strip damage it already leads to a poor surface quality of the final product and thus to rejects.
  • the deformation work to be performed increases with partial differences in density of the material to such an extent that even very small-scale density fluctuations, for example by fiber balls or glue lumps in the pressed material to pressure points on the surface of the steel strip or even destruction lead the steel strip.
  • a Pressgutmatte also called form strand
  • a control of the pressed material mat by means of a basis weight scale and / or a density control.
  • Usual are further Magnetic separators and search coils as metal detectors, prepressing for precompression, trimming of the longitudinal sides of the pressed material mats and before a cycle press a necessary Mattendorfzelung.
  • a Fehlchargenschacht or junk bunker to unfavorably scattered or sprinkled with faulty material Pressgutmatten before the press inlet quickly and safely remove from the mold string and prevent compression.
  • the underlying idea is actually to save raw materials, because from the disposal bunker, the materials used are usually reintroduced into the raw material processing and used again at the next opportunity.
  • Defective surfaces of steel belts of a continuous press are harmful for the surface quality of the product, on the one hand, and on the other hand, the steel belts are sometimes the most expensive parts of a continuous press and cause a long production loss with each replacement.
  • the conversion of production in width or thickness of the material plates may also be a reason to interrupt the pressed material mat and to empty the continuously operating press.
  • the invention has for its object to provide a method for the production of material plates with a continuously operating press, in which the steel strips and other machine elements are protected by the incalculable run-in behavior of crushed pressed material mats and a Specify an installation for carrying out the method, with which it is possible to prevent damage to the steel strips occurring through the entry of irregular press material mat edges across the width.
  • the solution for the method according to the invention consists according to claim 1 in that before the continuously operating press over the width of the Pressgutmatte running separating cut is performed to pass existing ends of a pressed material always with straight edges transverse to the transport direction to the continuous working press.
  • the solution for a plant for carrying out the method according to claim 14, consists of one or more scattering stations, with associated forming belt, subsequent monitoring devices of Pressgutmatte, a pre-press, a discharge bunker and a continuously operating press in the direction of production before a continuously operating press for the pressed material one or more separation devices are arranged over the production width.
  • the pressed material until the separation cut continues to be disposed of via the discharge bunker and the forming belt after dropping the pressed material until the separation cut with the Studentsgabase bridges the discharge bunker and so the Pressgutmatte to the continuous working press with a rectilineal press mat edge.
  • a separating cut is also carried out, in which case the straight-line separating cut at the end of the incoming pressed material mat should facilitate the transition from production to idling.
  • the discharge behavior of the pressed material mat when opening the discharge bunker is improved.
  • the suction device can either be arranged along with the separating device or fixed over the entire width of the pressed product mat and is mounted according to the start-up or shut-down operation in or against the production direction to the separation device.
  • the separating cut is carried out by means of cutting rotary tools such as milling or sawing. It makes sense not to perform the separation cut completely by the scattered Pressgutmatte, but at a predetermined safety distance to each lying below the forming or intermediate band, so this can not be damaged.
  • the separating cut be carried out by means of a arranged over the entire width lowerable cutter bar.
  • the separating cut of the separating device is carried out perpendicular to the Pressgutmattenlteilskante. This is to facilitate the outflow of excess air inclusions in the inlet wedge of the continuously operating press. Because the outflow behavior of the pressed material mat in the inlet or in the wedge compressor of the continuously operating press is an important criterion and also influences the maximum production speed.
  • the present method is applicable in the production of thin MDF or HDF material plates below 5 mm, being driven with a forming belt or a production speed of 700 to 2500 mm / s.
  • the separation cut is not limited to the implementation of a narrow slit by means of a dicing saw, but two cuts can be introduced at a predetermined distance in the pressed material mat. The distance is chosen so that between the two separating cuts 40 mm to 1200 mm are available. In this case, the pressed material mat between the two separating cuts either sucked off or pushed down from the forming belt.
  • This variant is useful at high feed speeds or high production speed, so that the control technology control of the retracting Studentsgabease also safe the Separation cuts and not on incorrect control of the cut edge destroyed and thus a broken Pressgutmattenkante enters the press, either at the beginning of a new production or at the end or an emergency discharge of Pressgutmatte in the discharge bunker.
  • a Pressgutmatte 9 is scattered by means of one or more scattering machines 1 on a forming belt 8 and thereby guided continuously in the production direction to the continuously operating press 7 out.
  • the scattered Pressgutmatte happens while a Formbelwaage 2 for Examination of the spreading quality of the spreading machines 1 and a pre-press 3 for precompression of the pressed material mat 9.
  • the pre-press 3 can also take over other functions such as temperature and humidity calibration.
  • the pre-compacted pressed material mat 9 is examined with a metal detector 4 for foreign bodies.
  • a radiation of the. Pressgutmatte 9 or any other suitable method of investigation are used to detect high-density non-metallic foreign bodies such as glue lumps in the spreading material 9 of the pressed material.
  • the pressed material mat 9 passes through a separating device 5 and the discharge area 18 of the discharge bunker 6.
  • the discharge area 18 or the discharge bunker 6 is bridged by means of the transfer nose 16 and the forming belt 8.
  • an intermediate belt 19 which transfers the pressed goods mat 9 to the continuously operating press 7.
  • a material plate is pressed using pressure and heat from the Pressgutmatte 9. This is done in the present drawing by means of a continuously operating press 7, designed as a double belt press with top and bottom arranged endless rotating steel belts 11 which are guided around idler pulleys 10.
  • a roll bar circulation 12 is arranged between the heated pressing plates 13 and the steel strips 11.
  • the continuous press 7 and a calender (not shown) can be used.
  • the respective continuous press is followed by a final production (not shown). If it is decided during production to open the discharge bunker 6, the separating device 5 comes into action and performs a separating cut across the width of the pressed product mat 9. This separating cut ensures that a straight cutting edge of the pressed material mat 9 enters the continuously operating press 9, while the subsequent parts of the press material mat 9 fall properly during the process of the transfer nose 16 in the discharge position 14 on the baffle plate 17 and then in the discharge bunker 6. There, the Pressgutmatte 9 is divided or broken and recycled.
  • a separating cut is carried out by the separating device 5 in preparation for the production.
  • the transfer nose 16 stands in discharge position 14 and is moved over the path k in the direction of continuously operating press 7 to the transfer position 15 when the straight cut edge of the pressed material mat 9 has reached the transfer nose 16.
  • the driving speed of the transfer nose 16 is equal to or greater than the current feed of the forming belt 8.
  • a Separating device 20 may be arranged on the intermediate belt 19.
  • the excess parts of the Pressgutmatte 9, which should not retract into the continuous press 7 are otherwise disposed of, for example, by suction or pushing away.
  • suction units 21 are arranged on both sides of the separating device 20 for this purpose, which provide for the removal of the excess parts of the pressed material mat 9.
  • the suction unit 21 can also be arranged only one foldable over the separator 20 suction unit 21, which is folded as required at a separation cut at the beginning of a retractable Pressgutmatte 9 in the production direction after the separator 20 in the direction of continuously operating press 7 and for a separating cut at the end of the retracting Pressgutmatte 9 is folded to the other side of the separator 20.
  • the suction unit 21 will be arranged to wait as described last to be ready for an emergency separation cut. In the starting operation, however, stands the suction unit 21 between separator 20 and continuously operating press 7 to 18 after extraction of the discharge area to pick up the irregular incoming Pressgutmatte 9 to carry out the separation cut.
  • the press material mat 9 at high feed speed before it breaks off and falls into the ejection bunker 6 still spans the ejection region 18 for some time due to internal stress. Especially with high-speed presses could thus foreign objects reach the continuously operating press 7 and cause damage.
