Definitions
- the invention relates to a microwave heating system for producing laminated profiled wood, as described in the preamble of patent claim 1, and to a method therefor, as described in the preambles of patent claims 18 and 19.
- the object of the present invention is to create a device and a method with which the production of profiled wood assembled from several lamellae is possible with short production times and / or higher quality.
- the surprising advantage here is that the heat achieved with the heat and / or wave energy source, in particular the microwave, in the lamellae or in the lamella package achieves a very rapid and uniform temperature over the entire cross-section and a uniform and high degree of dryness, whereby a high quality of the connection is achieved with a greatly reduced setting time.
- a design according to patent claim 4 is also advantageous, because this results in a uniform heating process even in the case of lamellae or lamella packs which have a large width.
- a further advantage is an education according to claim 5, because heat and / or wave energy from the heating area is prevented.
- a favorable further development is represented by patent claim 6, which enables a shortening of the heating time, in particular in the case of lamellae or lamella packs of great length.
- an embodiment according to claim 7 is also advantageous, as a result of which the uniform heating process is improved.
- a further development according to claim 8 is advantageous because it avoids further openings in the housing and thus an impairment of the tightness of the radiation chamber.
- a design according to claim 9 is also advantageous, as a result of which heating of lamellae or lamella packs of great length is accomplished.
- a further advantage is an embodiment according to claim 12, because it enables a 90 ° division angle ratio of the loading direction to the direction of removal and thus a flexible installation of the device in the manufacturing process.
- An embodiment variant according to patent claim 15 is also advantageous because this means that a vertical direction of advance of the slats or plate packs into a heating range is reached.
- An embodiment according to claim 17 is also possible because this means that the level of the heating devices upstream or downstream of the heating devices is the same as that of the heating device.
- a further independent, advantageous method variant can be found in the features of patent claim 19.
- the advantage here is that the individual lamella is heated by thermal and / or wave energy, and subsequently, after the binder has been applied, the lamellae stacked to form a lamella package are subjected to a pretension in an intermediate storage position, which accelerates the manufacturing process Consequence.
- an embodiment according to claim 21 is advantageous because in this temperature range, a uniform heating of the cross section is achieved without reaching a maximum permissible surface temperature and at the same time accelerating the drying process of the binder.

- This closure panel 75 is pivoted into the heating device with the lamella 3, for example by means of pressurized cylinders 76, into a position exposing the insertion opening 57. Before the microwave generators 65, 66 are put into operation, this closure panel 75 is pivoted to shield it from the insertion opening 57.
- the use of sensors 77 and a monitoring control 78 ensures, for example, that the microwave generators 65, 66 can only be put into operation when the shutter 75 is closed.
- the opposing arrangement of the microwave generators 65, 66 ensures a short cycle time when heating a lamella 3 or a stack formed from the lamellae 3 and furthermore ensures uniform and distortion-free heating and a subsequent rapid setting process when the lamellae are connected 3 by means of a connecting means, for example an adhesive for producing the raw profile 2. Furthermore, it would also be possible, additionally or exclusively, to arrange the microwave generators 28, 65, 66 only on one vertical side surface of the housing 54.

- the transfer of the plate pack from the removal station to the platform 91 by means of the crane system 88 can, however, be replaced by a height-adjustable design of the removal station, e.g. as a schematically illustrated scissor lift platform 92, whereby the crane system 88 or the manipulation device 89 arranged thereon only serves to put on the clamping frame 90.
- Vertical positioning can, however, also take place directly through the height-adjustable support 4 of the heating device 1.
- the lamellae 3 can be formed from short goods in a preliminary process by connecting at the end in the form of a so-called finger-jointing and gluing. In this way, defects in the slats 3 can be avoided or the waste rate is reduced.

- the heat generated by means of the microwaves remains effective for a long time, as a result of which the setting process of the connecting means in the pressing device 87 is accelerated after the raw profile 2 has been formed.
- a further possibility is the use of a wave energy source after the formation of the package of the lamellae 3 before the tensioning frame 90 of the pressing device 87 is applied.
- a preferred embodiment for using a wave energy source is formed by the microwave generator 28, 65, 66 in the guide arrangement 22 which can be moved in the direction of the longitudinal extension of the slats 3 or the package, as a result of which a uniform and rapid heating process is achieved.
- the package is removed from the lamellae 3 in the direction transverse to its longitudinal axis by means of a conveyor device 93, e.g. Roller conveyor, belt conveyor, etc., conveyed to the ready platform 91 or subsequently to a respective layer 94, formed from the tensioning frame 90 with the raw profile 2 stretched therein.
- a conveyor device 93 e.g. Roller conveyor, belt conveyor, etc.
- the manipulation device 89 which can be moved on a crane system 88 and with a support frame 95, is used to place the clamping frames 90 on the pack of the slats 3 and, using an adjusting device 96, clamping jaws 97 into the pressing position, in which the pressing force - arrow 98 - is applied to the package of lamellae 3.
- One of the layers 94 is thus formed and the process for forming an entire stack is repeated, the platform 91 which can be moved by means of rails 99 being transferred to an intermediate store 100.
- the package of the lamellae 3 remains under the pretension by the tensioning frame 90 for a required setting time until the required adhesive force of the connecting means is reached.
- the intermediate storage 100 can thereby ventilation devices 101 and heating devices 102 in order to complete the setting process accelerate, show.
- ventilation devices 101 and heating devices 102 can also be provided.
- the unstacking and the delivery of the raw profile 2 take place.
- the layers 94 are picked up individually from the entire stack by means of a lifting device 103 arranged on the manipulation device 89 and transferred to a conveyor device 104, for example a roller conveyor 105, by means of the crane system 88, whereby at the same time during the process, the clamping frame 90 the adjusting device 96 can be opened.
- lifting forks 106 are moved into their rest position by means of an actuator 107 and thus the raw profile 2 is released and removed via the conveying device 104.
- the clamping frames 90 which are held in their open position in receptacles 108 of the support frame 95, are now available for a further assembly process for a package of the slats 3 provided in the press station and thus return to the production process.
- the emitted wave energy used in this process for the microwaves to act on the plate pack and / or the plate has a wavelength of 1 mm to 1000 mm at a frequency of approximately 2500 MHz.
- the temperature generated by the microwave is between 40 ° C and 80 ° C, preferably 60 ° C.
- the housing 27, 54 and / or one of the microwave generators 28, 65, 66 can be adjusted in height with the waveguide device and the housing or a housing jacket as a protective screen to prevent the passage of waves are trained.
