Definitions
- the invention relates to a device for gluing wooden profiles made of rod material, for. B. T and I profiles, by means of high frequency, consisting of an aligned receiving the rods of the profile underlay, one acting from the side in the direction of the glue joint (s) tensioning device and one passing the clamped profile between fixed electrodes of the HF device Conveyor.
- Gluing by means of high frequency has been known in wood construction for decades, but is limited in practice to a few applications, since either the shape of the glue joint is not suitable for this or the narrow tolerances required for HF application cannot be complied with during the manufacture and assembly of the individual parts. For this reason, wooden profiles for beams, trusses, supports, etc. are still largely glued using conventional technology. In the case of T and I profiles, the straps have so far mostly been grooved on the sides facing each other and placed on the web according to the glue information. With these profiles, however, HF gluing is already known, the profile being placed flat, that is to say parallel to the web, on a base and being drawn in by endless pressure bands acting laterally on the outside of the belts. These pressure bands, which thus also form the tensioning and conveying device, transport the profile past the fixed electrodes of the HF device, the glue setting and the finished profile being released behind the HF device.
- the invention has for its object to provide a device of the structure described above so that perfect profiles can be obtained in every respect.
- the conveying device is a path that receives the profile between its side cheeks and the bottom, the length of which corresponds to the greatest length of the profile to be processed and at least one of the side cheeks has the tensioning device, and that in the conveying direction in front of the HF
- a stationary pushing device for straightening the bars of the profile by pressing against the support and at the same time aligning them in their relative position to one another is arranged, the pushing device first taking action and only after its working cycle the clamping device which activates the profile even after being released from the stationary Press device holds in the aligned position.
- the pressing device consists of a plurality of pressure cylinders which are distributed over the length of the profile and act on the bars of the profile.
- Each pressure cylinder can be assigned a pressure piece which is adapted to the upper sides of the bars of the profile in their relative position to one another, so that one can get by with a minimum of pressure cylinder.
- the carriage is guided on running rails which are laid between a feed station, the pressing device, the HF device and a removal station.
- the trolley can either be moved back and forth between these stations and facilities or it can also be guided in an endless path from the loading station to the removal station and from there back to the loading station.
- Such an endless path can be circular in a horizontal plane or formed from linear sections with sliding platforms. However, it can also have a return path arranged above or below the floor with lifting devices in each case at the head ends.
- a preferred embodiment of the invention is characterized in that the tensioning device consists of one or more pneumatic pressure chambers arranged on a side cheek of the carriage. For example, one or more can be along a side cheek of the car. hoses divided into chambers, which are filled with compressed air to tension the profile.
- This embodiment ensures a constant pressure over the entire length of the profile and is otherwise less prone to failure. It is also particularly economical from an operational point of view, since compressed air is available in practically every wood processing company.
- the force exerted by the tensioning device from the side onto the profile is a multiple of the force exerted by the pressing device in the vertical direction, so that it is ensured that, after being released from the pressing device, the bars of the profile do not deform back or move against one another.
- the base in the carriage and / or the pressure pieces of the pressing device are designed as templates adapted to the profile contour and can be exchanged for templates for other profile contours. As a result, a minimum set-up time is achieved when switching to other profiles.
- the electrodes of the HF device are arranged on holders and can be adjusted to different profile contours, so that only short set-up times are required on the HF device when changing over to other profiles.
- the electrodes of the HF device are provided with sliding shoes which act as spacers and which bear against the bars of the profile in the region of the glue joint (s). It is also expedient if the electrodes are under them by spring force pressing against the glue joint (s). This ensures that, on the one hand, the electrodes are always arranged as close as possible to the glue joint (s) and, on the other hand, are always at the same distance from the glue joint (s). This is crucial for the quality of the gluing.
- an I-profile 1 is to be glued.
- the bars forming this profile 1 consist of the web 2 and two straps 3 adjoining its longitudinal sides.
- the device initially has a conveyor in the form of a carriage 8 which can be moved on rails 4, 5 by means of rollers 6, 7.
- at least one roller 7 is designed as a guide roller, for example with a double flange, in order to guide the carriage 8 with as little play as possible.
- on-board castors can of course also be provided.
- the carriage 8 has a bottom 9 and mutually opposite side walls 10, 11, between which the bars of the profile 1 are received.
- One of the side cheeks - the side cheek 11 in the exemplary embodiment shown - has a tensioning device, which is indicated schematically in the drawing by a tensioning surface 13 and a directional arrow 14. This tensioning device acts from the side on the left belt 3 of the profile 1, while the other side cheek - optionally with the interposition of a wooden board or the like. Serves as an abutment for the other belt 3.
- the device also has a stationary pushing device 15, which in the exemplary embodiment shown consists of a plurality of gallowshaped supports 16 (FIGS. 1 and 2) arranged one behind the other at a distance, each of which has a vertical pressure cylinder schematically indicated by the directional arrow 17.
- the pressure cylinders work over one or more Thrust pieces 18 on the top of the web 2 and the straps 3 so that they are under the same pressing force.
- the pressure piece 18 can be designed as a template according to the upper profile contour.
- the web 2 and the belts 3 are pressed against the base 12 by means of the pressure cylinders 17 and are both directed and aligned with one another.
- the clamping device 13, 14 is put into operation, and the profile 1 is clamped laterally, the clamping force being approximately three times the pressing force.
- the printing cylinders 17 are then moved into their starting position, that is to say the carriage is released by the pressing device 16, so that it can be moved to the HF device shown in FIG. 3.
- the HF device 19 has two upper electrodes 20 as hot electrodes and two lower electrodes 21 as cold electrodes, between which the profile 1 with its web 2 is moved by means of the carriage 8.
- the electrodes 20, 21 have sliding shoes 22 at least at their ends, which are chamfered in the inlet area and serve as spacers to the web 2 or to the belts 3.
- the electrodes are preferably under a spring force in the vertical and horizontal directions, so that a constant spacing from the glue joint 24 (see FIG. 3) is ensured by the sliding shoes 22 acting as spacers.
- the uniform pressure can be ensured in a simple manner in that the electrodes 20 sit on a holder 26 via a joint 25, which in turn is under the action of a vertically arranged spring.
- the position of the electrodes 20, 21 can be adapted to different Profi I shapes.
