Definitions
- the invention relates to a dosing hopper for the production of wood-based panels according to the preamble of claim 1.
- dosing bunkers are installed upstream of the actual scattering elements. These make it possible to compensate for a change in the volume of the chips, fibers or chips (beaches) over time. At the same time, they should enable the spreading heads to be fed continuously. For this purpose, in particular a uniform distribution of the chips, fibers and chips (strands) over the entire width of the spreading heads is already carried out in the dosing hopper and a continuous stream of material is fed to the spreading heads.
- Both vertical and horizontal dosing bunkers are known in practice.
- the vertical dosing bunkers were usually arranged vertically over the entire spreading width of the spreading heads and filled with glued wood shavings continuously or discontinuously up to a predetermined filling height.
- Such vertical dosing bunkers are very simple, the chips being moved from top to bottom without mechanical conveying elements only by their gravity.
- A are bunker floors.
- Discharge rollers arranged, which convey the chips to the scattering elements.
- the vertical bunkers have become less important in recent years because different densities form on the bunker floor depending on the filling level. This has the disadvantage that, depending on the material density on the bunker floor, there are different discharge quantities to the spreading heads.
- horizontal dosing bunkers have preferably been used in front of the spreading elements, which have a largely constant discharge density when wood chips are discharged.
- a horizontal dosing bunker is known from the specialist book by Deppe / Ernst, Taschenbuch der Spanplattenentechnik, 3rd edition 1991, page 255.
- the horizontal dosing hopper is arranged above a spreading head and is loaded with wood chips from above.
- a horizontal swivel conveyor is arranged above the storage housing, which continuously distributes the chips over the entire spread.
- Horizontal dosing hopper a combing device is provided, which ensures a uniform filling height over the entire width of the bunker by the higher lying
- Wood chip piles are continuously combed back against the direction of discharge.
- a floor conveyor is also arranged on the bunker floor, which conveys the uniformly high chip layer in the bunker to a discharge opening above the spreading head.
- the chip layer is conveyed against rotating discharge rollers, which mill the layer over the entire filling level and at the same time convey it into an output opening to the spreading head in order to be scattered onto a forming belt.
- long flat wood chips (strands) for the production of oriented chipboard (OSB or LSL) are to be stored temporarily in such a horizontal dosing bunker and distributed over the width, then tangled wedges in the horizontal bunker occur in particular due to the continuous combing back of the elongated wood chips.
- the invention is therefore based on the object of creating a metering bunker for the production of wood-based panels from which a uniform discharge amount, in particular of elongated flat wood chips (strands), is conveyed into the spreading head over the entire bunker width.
- the invention has the advantage that a uniform discharge quantity is always available for spreading through the weight-metered material input over the entire bunker width, even with different bulk densities, which enables a very uniform spreading and an increase in the bending stiffness in the production of OSB panels is achievable.
- the spread fluctuation range is reduced at the same time, so that the minimum requirements for specified quality features can be met even with minimal use of spreading material.
- the elongated flat wood chips (strands) are additionally aligned in the transverse or longitudinal direction before they are deposited in the bunker. This has the advantage that the entire Do- sierbunker a uniform density distribution and a raised stabili ⁇ stocks amount to the same storage room hung unavailable. Thereby, a hooking of the elongated flat wood chips is avoided at the same time, so that advantageous ⁇ legally be dispensed at the discharge opening of the hopper elements.
- the pre-oriented wood chips are deposited in a vertical bunker and continuously withdrawn via a vertical conveyor shaft.
- the pre-orientation advantageously avoids the formation of bridges in the bunker and a uniform material discharge is achieved.
- An additional special embodiment of the invention provides that a jam-free horizontal filling section is arranged as a continuation on the vertical conveyor shaft. A loosening of the material structure on the horizontal conveying path is thereby advantageously achieved, so that a uniform weight-metered discharge is made possible.
- Fig. 1 a vertical dosing hopper with pre-oriented weight-dosed material entry
- Fig. 2 a horizontal dosing hopper with pre-oriented weight-dosed material input.
- a vertical bunker 1 for the production of OSB or LSL boards is shown schematically, which in essentially consists of an entry device 2 and a weight-detecting swivel conveyor 4 for the weight-dosed and oriented entry of elongated wood chips (strands) in a vertical filling space 3 5 arranged underneath.
- orientation rollers 7 are provided below the opening rollers 6, in the slots of which the elongated wood chips 35 slide in transversely to the conveying direction.
- the Ori Ent michswalzen 7 consist of a continuous drive shaft around which star plates are provided. The distances between the cross plates represent tapering slots that are only wide enough that the chips can only slide in transversely.
- the orientation rollers 7 could also be arranged in the conveying direction, so that the elongated wood chips would be oriented lengthways. For longitudinal orientation, however, disk rollers can also be used, through the slots of which the elongated wood chips would be aligned in the longitudinal direction.
- a swiveling conveyor belt 4 is arranged below the orienting rollers 7 as a swiveling conveyor, onto which the pre-oriented wood chips are fed by the orienting rollers 7.
- the conveyor belt is provided with transverse webs 8 or transverse plates, which form conveyor pockets 9 between the individual webs 8.
- the distances between the crosspieces 8 or cross plates are dimensioned such that the wood chips can only be inserted in their Que alignment in the conveyor pockets 9, so that the transverse orientation on the swivel conveyor belt 4 is maintained.
- the conveyor belt could also be provided with longitudinal webs which only take up the wood chips in the longitudinal direction.
- the pivoting conveyor belt 4 is pivotally and horizontally pivotable at its feed area and lowered obliquely downwards to the horizontal in the conveying direction.
- the bend of the swiveling conveyor belt 4 is arranged to be immersed in the vertical filling space 3.
- the swiveling conveyor belt ' 4 is connected to a known swiveling drive, not shown, which swivels the relatively narrow conveyor belt 4 of maximum 1 m width back and forth over the entire width of the bunker.
- the elongated wood chips are deposited in layers over the entire width of the bunker.
- the width of the bunker roughly corresponds to the spreading width in the Usually is two to four meters.
- As oscillating conveyor and also a parallel conveyor could be provided in the continu ous ⁇ and the tape direction parallel to the For forth over the hopper width, and is moved reciprocally.
- a belt scale 23 is provided in the swiveling conveyor belt 4, by means of which the conveying strength of the wood chips being conveyed is determined.
- the transversely oriented wood chips can be deposited in a weight-metered manner over the entire width of the dosing hopper 1 or the vertical filling space 3. It is provided that the same weight of wood chips is always deposited over the entire width of the bunker so that the vertical filling space 3 is filled evenly. For this reason, a constant conveying force is specified at which the belt speed can be readjusted in the event of a deviation from the target weight, the swiveling speed remaining constant.
- a given delivery rate could also be regulated via the swivel speed. Since the swiveling conveyor belt 4 is inclined in the conveying direction, the inclination of the conveyor belt 4 is detected by an inclination sensor in the case of the weight-metered discharge or is taken into account by calculation at a constant inclination angle. For this purpose, an evaluation device, not shown, is provided, by means of which both the belt loading and the belt speed are detected. If there is a deviation from the specified conveying strength or from the target weight, the belt speed of the conveyor belt 4 or the swiveling speed is adjusted accordingly.
- the distance of the discharge point of the conveyor belt 4 from the depositing point in the vertical filling space 3 should not exceed a certain height distance. It is therefore provided that the swiveling conveyor belt 4 is adjustable in the conveying direction 10, so that it can plunge more or less deeply into the vertical filling space 3. This can be carried out in a simple manner with a lifting cylinder or a spindle drive. For this purpose, additional fill level sensors, not shown, are provided which, by means of a program-controlled evaluation device, maintain a constant distance from the wood chip surface in the vertical fill chamber 3.
- the vertical filling chamber 3 consists in its filling area of an upper filling shaft 11, which consists of rigid parallel side walls 12, 25 which run across the entire width of the bunker. These are fastened on the end face to the outer wall of the bunker and form a tightly enclosed filling chamber 11. Below this upper filling shaft 11 there is a vertical conveyor shaft 13 which essentially consists of two vertically arranged discharge conveyor belts 14, 15 which have a horizontal deflection in their lower area 16, 20 experienced. These belts 14, 15 extend over the entire width of the bunker and, together with the end walls of the dosing bunker 1, form an enclosed conveyor shaft 13 which continuously conveys the contents of the bunker to a discharge opening 24.
- the two discharge belts 14, 15 are each an endless belt, which is arranged between three deflection rollers 16, 19, 20, which are arranged approximately like the end points of a right-angled triangle.
- the two conveyor belts 14, 15 each connect to the lower point of the side walls 12, 25 of the upper filling shaft 11 and thus form its extension.
- the two discharge belts 14, 15 are arranged so that they have different roller spacings.
- the roller spacings are provided so that both a vertical 13 and a horizontal conveyor shaft 18 are formed between the two conveyor belts 14, 15.
- the directed wood chips are conveyed to a discharge opening 24 in these deflected shafts 13, 18.
- the vertical conveyor shaft 13 is designed as a clamping section in which the shaft can be narrowed downwards at least on an inner side surface.
- the lower discharge belt 15 rests only loosely on its support rollers 17 and the shaft width is adjustable with a horizontally adjustable tensioning roller 16. Due to the narrowing of the shaft width, the layers of the oriented wood chips are clamped in at the side, so that they are carried along in the conveying direction by the movement of the discharge belts 14, 15. It is thereby achieved at the same time that the individual layers in the lower region of the vertical conveyor shaft 13 are not significantly compressed by the fill level, so that an easily detachable bed in the vertical shaft 13 is retained.
- the vertical conveyor shaft 13 can be closed so far in the deflection area with the aid of the tensioning roller 16 that the two discharge belts 14, 15 lie slightly against one another with their inner walls. This prevents the newly filled wood chips from slipping through to the discharge opening 24. At the same time, the vertical shaft 13 is reduced to such an extent that the discharge height is only so great that an oriented depositing in the vertical conveyor shaft 13 is guaranteed.
- the level is detected by the level sensors and transmitted to the evaluation device. This controls the tracking of the swiveling conveyor belt 4 in the conveying direction 10, so that the distance to the filling level remains the same until a predetermined filling level is reached.
- the belt tension can be loosened by the adjustable tensioning roller 16 to such an extent that a continuous discharge is made possible.
- the lower shaft width can be increased so far that it corresponds to the shaft width of the upper filling shaft 11.
- the material flow rate to be filled is increased until a total filling level in the vertical filling chamber 3 is reached.
- a given feed rate is determined over a given discharge quantity, which distributes the wood chips evenly over the entire width of the bunker and at the same time keeps the filling level constant.
- the level sensors can be distributed on the front of the bunker in such a way that they also measure the level across the width of the bunker.
- the swivel conveyor belt 4 can also be arranged horizontally and transversely to the width of the bunker, so that a constant filling height can also be achieved across the width of the bunker.
- the lower tensioning roller 16 of the lower discharge belt 15 and the upper tensioning roller 20 of the upper discharge belt 14 direct the vertical discharge flow into a horizontal discharge flow. This advantageously prevents the vertical material flow from slipping through to the discharge opening during discharge operation. At the same time a loosening of the compaction effect is achieved, so that a gentle, even discharge into the spreading head is made possible.
- the vertical filling space 3 could, however, also be formed by one or two parallel conveyor belts which are directed at two horizontal conveyor belts, which then form the horizontal filling shaft. However, a cellular wheel sluice could also be provided below the vertical filling space 13, through which the oriented wood chips are discharged into the spreading head in the manner of the orientation rollers.
- the horizontal discharge stream in the horizontal conveyor shaft 18 represents a jam-free filling section which forms a horizontal catalyst.
- This horizontal filling section 18 serves primarily to bring about a uniform discharge behavior. This is achieved primarily by the fact that the deflection loosens the vertical stratification so that a uniformly dispensable material flow is established in the horizontal shaft 18.
- the belt speed of the two discharge belts 14, 15 can be regulated.
- the belt speed of both discharge belts is regulated so that they ensure a constant discharge speed in the shafts 13, 18, so that the pre-orientation is not changed and material circulation in the shafts 13, 18 does not occur as far as possible.
- a belt scale 22 is preferably provided at the belt end of the horizontal conveyor shaft 18, by means of which the discharge quantity can be regulated via the discharge belt speed.
- a knock-off roller 21 is additionally provided, which gently combs the oriented wood chips into the outlet opening 24 to the scattering chamber.
- the vertical bunker 1 ensures careful storage and even weight-metered discharge of the elongated wood chips, so that these can develop their maximum strength in the OSB panels to be spread and are not impaired by the proportion of fine material which has arisen.
- the entry device 2 arranged in the vertical bunker 1 could, however, also be provided in a separate device part above the bunker housing, if this is possible and advantageously feasible for design reasons.
- the horizontal bunker 30 consists essentially of a horizontal filling section 32, which is formed from a floor conveyor 33 and the entry device.
- a screw conveyor 5 which feeds the glued elongated wood chips (strands) from a gluing mixer.
- This screw conveyor 5 speaks of the screw conveyor according to FIG. 1 of the drawing, the same reference numerals also being used for the similar parts in FIG. 2 of the drawing.
- the entry device 31 essentially consists of the orientation rollers 7 and a swiveling conveyor 4.
- the elongated wood chips for the production of OSB panels are first placed on at least two opening rollers 6 and the orientation rollers 7 arranged underneath.
- the swivel conveyor 4 which is formed from a conveyor belt provided with pockets 9, is arranged below the orientation rollers 7.
- the horizontal bunker 30 extends over the entire width of the spreading head, which can be up to four meters.
- the swivel conveyor 4, on the other hand, has a width of no more than one meter and is continuously swiveled horizontally back and forth over the entire width of the dosing hopper 30 and thereby distributes the wood chips introduced evenly over the width of the bunker 30.
- the swiveling speed is a multiple of the discharge speed , so that the oriented wood chips are layered on top of each other.
- the swivel conveyor 4 is arranged horizontally above the filling section 32 and conveys the oriented wood chips against the discharge direction 34 to the filling section.
- the swivel conveyor 4 can also be inclined with respect to the horizontal, so that the oriented wood chips can be deposited in the lower region of the filling section 32 in the start-up mode.
- fill level sensors (not shown) are provided, which record the fill height on the side surfaces across the bunker width.
- the inclination of the swivel conveyor 4 can be readjusted by means of the fill level sensors and a predetermined distance from the fill height.
- the swivel conveyor 4 is only readjusted until a predetermined filling level in the bunker 30 is reached. After reaching this predetermined desired filling level, the bottom belt 33 can be controlled so that the filling layer for the discharge Opening 41 is promoted.
- the swivel conveyor 4 can also be arranged such that it is also adjustable in the conveying direction 34. Characterized been a constant filling level in the conveying direction 34 could by means of arranged level sensors in the conveying direction by the L Lucassver ⁇ of the conveyor be adjustable position and possible Nach Schollunterbrechungen be refilled.
- a belt scale 24 is provided near the discharge end, which detects the amount of weight of the conveyed wood chips.
- the belt speed is regulated so that the wood chips are distributed over the width of the metering hopper 30 with a constant conveying force, so that a uniform filling quantity on the filling section 32 over the entire width of the floor band results with a predeterminable discharge quantity.
- a program or processor-controlled evaluation device is provided, as is used in known dosing belt scales.
- the floor band 33 consists essentially of an elongated horizontal part 35 and a shortened vertical part
- the bottom band 33 can be tensioned to different degrees.
- the belt can be shortened so much in the start-up mode that in the storage area 40 of the wood chips the loosely resting discharge belt 33 is so inclined relative to the vertical that the wood chips can be deposited on the discharge belt 33 in a largely oriented manner in the storage area 40.
- a belt scale 22 can also be provided in the bottom belt 33 at the discharge end, with the aid of which a provided discharge amount can be regulated via the belt speed of the bottom belt.
