Definitions

  • the invention relates to a device for spreading of Spreading material on a continuously moving surface as well Bunker for metered discharge of grit according to the preamble of patent claim 1 or claim 10.
  • fiber / glue knots especially in the production of thin wood-based panels of 2.5 - 8 mm and especially at high densities of 800 - 1000 N / mm 2 cause severe damage to the steel strips of continuous presses.
  • fiber opening rollers are usually arranged the dosing hopper and the spreading head assembly.
  • Fiber opening rollers usually consist of 1 or 2 pairs Opening rollers with very high speeds from 800 - 2000 Rotate revolutions per minute in opposite directions.
  • Object of the present invention is an apparatus for Production of wood-based panels as well as a bunker for to develop the device such that a qualitative high quality wood based panel can be made, and whereby a high throughput and a small footprint achieved is and continues to minimize the manufacturing and construction costs becomes.
  • fibers will be on every interface between the existing rollers Second, the relative velocity between neighboring spiny disks much higher, as the Add peripheral speeds and thirdly arises uniform obliquely downward fiber discharge with low air turbulence.
  • the invention sees in one Continuing the arrangement of wall elements before, the Divide flow into several streams.
  • the Wall elements are spaced from each other vertically and longitudinally to the conveying direction.
  • the wall elements adjustable. This can be through the Wall elements forming shafts opening individually downwards or closing. Furthermore, this is by this also an adjustability for the purpose of changing the spread imaginable.
  • Fig. 1 of the drawing is schematically a scattering station. 1 with a dosing bunker 2, a calming fan 3, a Scattering roller assembly 4 and a forming belt 5, to which the Material fleece 6 is sprinkled from free-flowing material, shown.
  • lignocellulosic and / or cellulosic particles different size such as fibers, chips and the like intended.
  • Zer production of fiberboard are usually with Binders provided using wood fibers.
  • Fig. 1 are in the discharge area 10 a plurality of individual opening rollers 12 in parallel spaced apart, wherein the opening rollers 12 starting from the bottom belt 8 in the vertical direction to the backscrap 9 out are arranged offset obliquely.
  • One by the Rotation axes of the opening rollers 12 extending plane E points in this case to a vertical V at an angle ⁇ .
  • FIG. 1 From the illustration to Fig. 1 is further apparent that the opening rollers 12 rotate counterclockwise are driven (arrows 13), wherein the top, the Backscrap rake 9 closest opening roller 12 in opposite directions is driven in rotation.
  • the opening rollers with in Compared to previous fiber opening rollers low speeds be operated from 200 to 800 rpm.
  • the opening rollers 12 each have one as a cylindrical Base 14 trained rotary shaft, with a variety Spacing disks arranged on the main body at a distance 15 are provided.
  • dissolving discs 15 are each spacers 16th inserted.
  • the dissolving discs 15 axially spaced apart the opening rollers 12 are arranged, projecting in the middle like it 2b is visible, in the interspaces of the on the adjacent opening roller 12 axially spaced Disintegrating discs 15.
  • the dissolving discs 15 are made of a Spring plate made.
  • the sheet thickness of the slices 15 is 1.5 mm in this embodiment.
  • the slices 15 have, as shown in FIG. 2a it can be seen, an annular portion of which evenly distributed over the circumference of the release elements 17 radially extend outwards, between which recesses remain.
  • the dissolving elements 17 are substantially rectangular educated. Furthermore, they are centered on their faces provided radially inwardly tapered recesses, so that at each opening element 17 end two tips 18th arise.
  • Fig. 2a, 2b is a combing state adjacent Opening rollers 12 shown.
  • Ü is a measure of the Overlap area of the slices 15 adjacent Opening rollers 12 referred.
  • Figs. 3a, 3b is a non-combing state represented, in which the slices 15 a gap distance S have.
  • Opening rollers 12 also designed with other constructive Be provided dissolving elements or spines or the like can.
  • the flow of glued fibers is through the narrow driven gap formed between the spines or teeth, whereby a fiber dissolution or destruction of fiber / glue nodes is achieved.
  • the dissolved material flow is in Connection to the opening roller assembly 11 in a arranged immediately downstream calming fan 3rd thrown (arrows P).
  • the calming compartment 3 consists of a housing part, in which a plurality of parallel wall elements 20 are arranged are.
  • the wall elements 20 are preferably as longitudinal to Conveying direction of the forming belt 5 aligned sheets trained and divide the housing part in several Calming chambers 21 (illustration Fig. 4).
  • the conveying direction is vertical to the material particles from the top Dosing bunker 2 arranged on the underneath To promote scattering roller assembly 4.
  • the soothing fan can but also be arranged obliquely to the vertical direction to at the same time to achieve a horizontal conveying component.
  • the reassurance fan can also oblique to the Be aligned delivery direction to the flow rate also to deflect laterally.
  • This arrangement can not have fibers on the top of the Deposit wall elements 20 and a fiber / Leimknoten Struktur can be prevented.
  • the wall elements 20 protrude starting from the opening roller assembly 11 in the vertical direction to short via a task flap 22.
  • the task flap can also in order to adapt to different panel thicknesses around the Rotary axis D to be pivoted.
  • the driven by the opening roller assembly 11 material flow gets into the calming chambers with high kinetic energy 21 of the calming fan 3 catapults.
  • the existing ones Air streams together with the fibers are now considered parallel Partial flows passed in the calming chambers 21 down.
  • the scattering roller assembly 4 consists of several parallel and Spreader rolls arranged transversely to the conveying direction.
  • the Spreader rollers are horizontal along the direction of conveyance rising line arranged to a uniform dispersion and to ensure a height limit.
  • the spreading rollers are here directly below the task flap 22nd provided and promote the free-flowing goods, preferably the glued wood fibers against the conveying direction.
  • an additional Conveying device may be provided which the flow of material glued fibers feeding a scattering head assembly.
  • the additional conveyor is here as feeder belt formed, which is continuously adjustable in flow rate the spreading head arrangement promotes, so that depending on the plate thickness and width of the scattering head assembly a predetermined amount is streubar on the forming belt.
  • FIG. 5 shows a further embodiment of a scattering station for spreading glued scattered goods in the course of production of fiberboard, in which the opening rollers each driven in pairs in opposite directions.
  • the opening rollers each driven in pairs in opposite directions.
  • the paired opening rollers with operated at different speeds, so at the Interface a relative speed between the Opening rollers are created, which leads to a resolution of the fiber / glue nodes leads.
  • the wall elements 20 are opposite to a stationary Housing part pivoted at least in some areas or slidably mounted so that the distances of the wall elements 20 from each other continuously or gradually adjustable are.
  • Fig. 7a shows a scattering station 1 '' 'in contrast to the variant according to.
  • Fig. 1 in the lower of Task door 22 facing area baffles 26 is provided are.
  • the wall elements 20, as well as the neck Fig. 7b can be seen in the lower area than Guide fork 25 is formed.
  • Guide fork 25 On the task flap are in Lengthwise spaced, the wall elements 20 each associated baffles 26 attached in the Fhaküngsgabeln 25 are guided sliding.
  • FIG. 8 shows a variant in which behind the opening roller assembly 11 a large-volume expansion space 27 is formed, wherein additionally via a suction duct 28 an indirect suction of the air takes place.
  • Heavy goods such as Glue / fiber lumps that are not dissolved or to separate other foreign bodies from fiber flow.
  • a Shaft 29 parallel spaced in front of the Austragswalzenan ever 11 a Shaft 29 are arranged with opening slots 30.
  • a screw 32 At the bottom Area of the shaft 29 is a screw 32, the the trapped in the shaft heavy parts from the Spreader carried out.
