Definitions

  • the invention relates to a method for processing wood or wood waste to profiled, shapely molded parts comparable to real wood products the wood is dried, crushed to less than 0.5 mm and then with binder up to 15% mixed and filled into a lower mold and by pressing on the upper mold and Heat supply is compressed and shaped, then as an intermediate and / or The end product is removed from the mold and, if necessary, completed with further molded parts become.
  • the invention also relates to a plant for the production of real wood products corresponding molded parts made of wood and with a profiled surface, with a dryer, a shredder, a mixer, the associated Silos and feeders for binders and a lower mold and upper mold receiving or having press for shaping with heating for the entered Mix.
  • So-called chipboards are made from wood chips and similarly processed wood produced by pressing, these chipboards then for the most varied Find uses. Aside from the fact that these particle boards are due of the large proportion of binder used is relatively large Own weight is a disadvantage that their further processing because of the Coming press process is difficult. There is a relative one smooth outer surface because of the binder used, but is the interior unstructured and dependent on many coincidences, so that the ones described above Disadvantages arise.
  • the high proportion of binders is also used for so-called MDF boards disadvantageous, with the surface of appropriately manufactured panels subsequently post-treated, d. H. in particular must be smoothed in order to foil or To be able to apply varnish.
  • a process for the production of honeycomb plates describes the DE-PS 24 12 538.0-44.
  • a method for producing pressed bodies is known from the DE-OS 40 18 433.1 known, wherein wood chips, sawdust and plywood manufacturing waste mixed with a high proportion of plastic material (10 - 20%) and then is pressed. Screw presses and similar presses are used, whereby mostly multiple presses are used.
  • the invention is therefore based on the object of a method and a system to create high-quality molded parts with corresponding from old wood or waste wood Structural specifications are economically producible.
  • the task is solved procedurally by defining the wood Wood chips are cut and then mixed intensively with the binder, that the mixture of wood shavings and binder is filled into the sub-molds and after placing the top molds in a press, taking into account the desired ones Contours evenly compressed and specifically heated and retouched in shape the hardening is removed from the mold, the contours in the upper and lower mold be adapted to one another before and / or during the molding and heating period.
  • Wood is dried to 4-6, preferably 5%. This drying process is running the shredding process. Compared to the prior art is reduced Energy expenditure worked. In addition, there is less fines, because wood chips are produced with moist wood.
  • This targeted machining of the starting material is achieved in particular if the wood is cut in a shredder, where wood chips with under 0.5 mm dimensions can be produced specifically.
  • a molded part that is clean and true to shape with regard to the contours is in accordance with Manufacture invention by the sub-molds an approximately uniform compression resulting, preferably shaped accordingly at the edges and slopes, preferably beveled or rounded, while the top shapes are precisely shaped, preferably be angular.
  • This special training of the sub-forms and the upper forms surprisingly bring a smooth or clean execution the desired contours for the molded part.
  • the mix is poured into the lower mold and can then be smoothed if necessary, so that on the edges and slopes could set a different compression, depending on their training and Arrangement to each other.
  • the output can be increased in a targeted manner without it being additional Significant investment is required by the mixture of wood chips and binders is compressed in parallel in two or more presses. This has already been pointed out earlier been that the heating of the mix in the form, d. H. in sub and The upper shape takes place so that the uniformity is maintained.
  • the invention before that upper and lower molds in a first press under compression of the mixture are locked, then heated in the closed form and cured, whereupon upper and lower molds are unlocked in a second press and then be emptied.
  • the actual molding process or better said the curing process can then take place at rest and in the intended time expire without the press remaining occupied. Rather, it stands for another or even several other pressing processes are available.
  • a further acceleration of the cycle time can be achieved by the lower and Upper molds run all round on a transport device and depending on. Need brought in or discharged and put on hold and / or on several Floor circulation transport facilities can be distributed. The process thus offers more Possibilities of variation both from the simultaneous production of corresponding Molded parts as well as their targeted shaping. So on different floors Different molding material can be produced or it can be put on hold molds on an unused floor are placed around then to be reintroduced if necessary. The exchange of the individual forms takes place on the level using switches and on the vertical using appropriate slopes or via elevators.
  • the invention provides that, if possible no fine material included in the mixing process and further processing becomes. Rather, it is envisaged that the wood is cut and with a sieve Mesh size 0.1 to 0.6 mm sieved and that the mixture of wood chips ⁇ 0.5 mm and binder is preferably bunkered before the molding process.
  • This material which is approximately 0.5 mm, can be in the form of fine Wood chips particularly well together with the binder in the specially trained Form processed and shaped.
  • that with such wood shavings have a sufficiently high strength Molded part with a completely smooth surface can be produced.
  • the lower mold by shaping and / or baffles is designed so that taking into account the surface shape and the intended Profiles of the finished molded part achieved approximately the same material compression everywhere becomes.
  • the entire shaping is carried out in accordance with this process step set in advance and chosen so that it covers the entire, quite large area of the molded part can achieve approximately the same compression.
  • the uniformity of the material compression is achieved by the fact that with and / or after filling the lower mold by sprinkling the mixture approximately flat surface of the filled mixture is produced with the help of sliders. Since the projections and recesses are also set accordingly, can with the Place the upper mold on the lower mold with the necessary same compression pressure be guaranteed over the area.
  • a further optimization of the method is achieved in that the molded parts after removal from the opened mold without a surface treatment or post-treatment of the contours with foil or varnish and then with other molded parts to complete wooden parts. Avoiding the Post-treatment steps significantly reduce the manufacturing effort and shorten the Cycle times.
  • a further variation of the manufacturing process is possible in that the wood component in the mixture in whole or in part by other, preferably chip-shaped or fibrous recycling products or non-recycled wood or targeted prepared wood from sawdust etc. or bevel-tight material with certain (short) Fiber length is supplemented or replaced.
  • fiber material for example a door, for its strength depending on the later Decisive advantages.

  • the sub and the The upper mold is assigned to a tool carrier, which has a transport device and a lock-in and lock-out switch is designed accordingly. Because of this training it is possible to feed the molds one after the other to the press and then continue the correspondingly influenced shape on the conveyor belt and empty and then fill it again with mixed material. Will the appropriate lower and upper forms are not required, they are removed or if they are needed, they can simply be introduced and always in the Circle.
  • a compensation, i. H. pressure equalization in the area of the profiles is particularly important possible because the lower mold is equipped with sliding pieces that match the profiles opposite and designed to ensure optimal compression are. Instead of or in addition to the edges and slopes, spaces are specified here, into which coating material can then be pressed, if this is to make it uniform compression in the entire area is necessary. It can by Sliding pieces the receiving volume can be adapted to the circumstances, especially when, as provided for in a further development, the sliding pieces can be moved against the force of a spring or via a hydraulic unit are trained. The sliding pieces are based on the spring force according to the optimal Compression positioned, as well as with the help of the hydraulic unit. In order to can surprisingly precise the shape of the surface of a Such molded part can be optimized, in particular it is possible to decorate on the Specify surface that are also more complicated in terms of shape.

About these spreaders an automatic loading of the molds can take place, taking this into account the profiles and projections to be specified later.
  • the feed is further optimized according to the invention in that the Feeding and / or the spreading machines a form generator which can be inserted into the mold or slide is assigned. As a result, the surface of the imported mix can be targeted and shaped.
  • the invention is characterized in particular by the fact that a method and a system is created with which even high-quality molded parts can be produced economically are. Because of the special procedure and the special training the system results in high throughput rates with short cycle times, in particular of the pressing process.
  • the presses themselves are only used to initiate and Implementation of the compression used while subsequently in the form of the Press pressure is maintained until the curing process is complete. However, this no longer requires the mold to remain in the press.
  • the Press can be used for other forms.
  • Another advantage is that special requests can also be catered for and that small production lots can be easily inserted, because only the exchange of the two-part Form is required.
  • the process and system are also identified by their versatility and variability, so that the decor and shapes changed and can be quickly and inexpensively adapted to changing market conditions can.
