Definitions
- the invention relates to a device for orienting elongated wood shavings, especially for the production of boards with oriented chips.
- OSB boards Long wood chips are used in the production of OSB boards (Strands) oriented on a ribbon, and then pressed into plates. Usually the wood chips have a length of 100 - 150 mm, a width of 10 - 30 mm and a thickness of 0.4 - 1.0 mm.
- the OSB panels are in the Usually a 3-layer structure, but recently for the purpose of use different glue systems also 5-layer boards getting produced.
- the middle-layer wood chips are transversely oriented and the top layer wood chips sprinkled lengthways on a ribbon.
- the arrangement gives anisotropic properties. Wood owns in Grain direction much higher strength than across the grain.
- the arrangement of longitudinally oriented wood chips in the top layers the bending load in the longitudinal direction of the OSB Panels subjected to tensile and compressive stress lead to high ones Flexural strength of the plate. In the transverse direction there is still one sufficient bending strength of the panels due to the transverse orientation Middle class reached.
- EP 0 175 015 describes one as a disk orienter trained mechanical device for longitudinal orientation known from wood chips.
- the operating principle of these disc orienters is based on that the diarrhea chutes are narrower than the length of the Do not pass wood chips and therefore the wood chips in a cross-oriented manner can.
- the wood shavings that hit the Disc orienters will not step straight through by moving the disc rollers in the same direction move and thereby change their orientation as long as until they are oriented approximately longitudinally and in the diarrhea slits can fall.
- the orientation head is spaced from the forming belt, respectively the forming litter mat arranged. Even if that Disc rollers almost touch the mat at the vertices, there are gaps between the vertices that lead to this can cause e.g. Wood chips passing upside down after they hit the mat, fall over, because the rear part no longer holds on to the disc rollers place. As a result, with this functional principle, no 100% Orientation can be achieved.
- this design has the disadvantage that the loading density is severely limited, i.e. it can only be a limited one Amount of wood chips to be fed per unit area. Otherwise it comes into the orientation rollers at the entry point to a backlog and constipation.
- This device there are several stationary alignment shafts provided that from side by side funnel-shaped wall elements tapering towards the forming band consist. This device has a high risk of clogging.
- From GM 297 07 143 is a device for aligning and Drop of elongated particles known at the degree of orientation the particles improved at high throughput can be.
- a mechanical orientation unit is provided, the vertical surfaces in the direction of movement of the base has, with adjacent straightening surfaces in opposite Direction are drivable. The movement of the straightening surfaces is parallel to the moving surface and also has movement components perpendicular to the base for longitudinal orientation of the wood chips.
- the elongated wood chips to be oriented transversely to the conveying direction are arranged in a variety of parallel to each other rotating rollers abandoned, the rollers over the said width radially outwardly extending blade elements have.
- the wood chips slide through this arrangement of the blade elements aligned transversely into the wedge-shaped spaces and can thus be placed aligned on the forming belt.
- the invention has for its object a device for Orientation of elongated wood chips of the aforementioned Kind in such a way that an improvement of the orientation quality and an increase in throughput simultaneous reduction in construction, assembly and maintenance costs can be achieved.
- orientation subjects that consist of a A plurality of spaced transversely or longitudinally aligned Orientation walls exist that immediately in the Connection to the discharge roller arrangement of the dosing hopper arranged and up to just above the forming belt or the top edge the mat will guide the wood chips optimally reached in the longitudinal or transverse direction on the forming belt. Due to the arrangement described above, the elongated Wood chips directly at the discharge point of the discharge roller arrangement into the orientation shafts of the orientation subject that are being formed discharged. Separate the discharge rollers the wood chips and throw them into the compartments with force.
- the configuration according to the invention is not vibrating or rotating, i.e. has moving parts the experiments surprisingly found that when entering in the orientation subjects there are no constraints and none Damage or breaks in the wood chips occur. There the wood chips thrown into the orientation fans with force constipation can be effectively avoided and a higher load is easily possible. Farther the length of the spreading head can be drastically reduced. As soon as the wood chips entered and oriented in the subjects orientation is no longer lost. The wood chips are in the orientation subjects until they hit the ribbon guided.
- Another advantage of the device according to the invention is in that a constant over the entire exit surface Distance of the orientation fan to the ribbon set can be. Since the orientation subjects are immediately in the Connection to the discharge roller arrangement only slightly below height of the dosing bunker can be saved become. In contrast to orientation units which like described in the prior art from orientation disk rolls or consist of vibratingly driven straightening surfaces, are not driven in the embodiment according to the invention vibrating or rotating parts necessary so that the Manufacturing costs, assembly costs and maintenance costs are considerable are reduced.
- the neighboring Orientation walls can be moved transversely and / or at least in Partial areas arranged pivotable at an angle to each other are.
- the Spread width can be varied. If the setting option of the Walls selected so that a constant entry width is set at the top and in a lower area the distance between the neighboring ones Changing walls to each other can result in a material distribution can be specifically influenced in the transverse direction.
- orientation walls at least in the lower Partially height-adjustable area, so that very easy to adapt to different spread Mat heights can be achieved.
- a particularly preferred embodiment provides that the Orientation walls articulated or slightly springy are attached to the housing part. Furthermore, the walls can only be hung over a few attachment points. Through this Training becomes a natural vibration of the orientation walls achieved during the spreading process, so that there is a risk of clogging is counteracted.
- An embodiment of fines is possible in which Orientation subjects in the middle in the lower area between adjacent. bearded orientation walls additionally triangular Partitions are arranged. With this training it falls Fines in the area in the orientation shaft in which the part walls are arranged and the fine parts are now better in the longitudinal direction due to the half shaft spacing aligned.
- a cross orientation subject is provided for cross orientation, the discharge roller arrangements arranged inclined towards the front is arranged, the orientation walls starting from the discharge roller arrangement to the forming belt arranged slightly inclined in the conveying direction are. This training improves the quality of orientation in Cross direction improved.
