Description

Patent Office

Description: The present invention relates to a processing plant for boards and the like and to a production line realized with this plant.

More specifically, the invention relates to a system of the type mentioned, which was especially developed and manufactured in order to enable the machining of wooden workpieces with large dimensions and a predominantly planar expansion in a small space, such as walls, plates and the like, preferably made of wood.

In the following the invention will be described with reference to the processing of panels and walls made of wood, but it is obvious that this description is not to be regarded as limited to this specific application.

As is well known, systems for processing flat wooden workpieces with very large surfaces are currently known.

These systems are generally used for the processing of walls for prefabricated houses or in general for panels used in construction.

Such processing systems usually include a frame, a work surface on which the plate to be machined can slide, and a stand that is movable on guides that are generally arranged to the side of the work surface. This stand is located above the work surface.

The processing systems are also equipped with a processing unit which is movable along the stand by means of a slide. The processing unit has a head with 5 axes, so it can be aligned with five degrees of freedom, three translational and two rotary, so that the various processing operations can be carried out on the plate surface.

These systems are usually used for cutting and milling the plate surfaces.

[0009] CA 2344960 A1 shows and describes a work table comprising a bridge which has a tubular element, end caps and a tool holder which can be moved vertically along an inclined work surface.

[0010] DE 10321686 A1 shows a processing machine for processing wooden panels with an inclined work surface, this machine having clamping devices, in particular suction cups and a large number of support positions and stops at the lower end of the work surface.

DE 202006021287 U1 shows a processing machine for processing wood with a 5-axis processing head, which is attached to a slide, wherein the tool can be a milling, drilling or cutting tool, for example.

EP 2660023 A2 discloses a device for processing wooden panels, which has a woodworking unit, a loading and unloading area, including panel magazines and a crane, the crane being movable on an elongated base with two parallel guide rails and having gripping devices.

A technical problem of such systems is their considerable space requirement, precisely because, as mentioned, they have to be designed to accommodate and handle plates with very large surfaces.

In addition, the plates or walls must be moved to a further processing station after processing and finally loaded onto trucks for their transport. Suitable means are required for these further operations, which also take up additional space.

It is obvious that this method in terms of both economic and

AT519 407 B1 2019-09-15 Austrian

Patent office is also complex on logistical aspects.

To reduce the space requirement exist in other industries, such as glass processing, systems with an inclined frame, such systems are generally equipped with a processing unit with only 3 linear translation axes, sometimes in combination with only one axis of rotation, and therefore are less flexible in processing and therefore unsuitable for line processing on wooden walls. The systems mentioned have systems for clamping the workpiece, which are not intended to enable milling operations that lead down through the work surface, while such operations are common in the wood wall machining sector.

Furthermore, the ejection protection devices used there would prove to be unsuitable or ineffective for the processing of wooden walls in these systems, since this is characterized by plates of greater thickness and processing which not only provide for cutting and drilling, but also for drilling and slitting. Finally, from a structural point of view, these systems are characterized by their monoblock construction, which for technical reasons does not allow for easy expansion, if there may be a need to be able to place workpieces with the larger dimensions typical of wooden walls.

In view of the above, the object of the present invention is to propose a processing system that takes up less space.

Another object of the invention is to propose a processing system which is suitable for being flexibly inserted into a production line.

A specific object of this invention is therefore a processing system, in particular for the processing of wooden workpieces with a predominantly planar extent, comprising a support frame which has at least a first and a second section which can be detachably coupled to one another, the first and second Portions of the support frame, when coupled to one another, form a work surface which is arranged inclined relative to the contact surface of the machining system and is used for placing a workpiece to be machined, and a machining bridge which is arranged such that it is positioned above the work surface , and which is movable relative to the support frame, wherein the machining bridge includes a machining head which is slidably coupled to the machining bridge and which is equipped with one or more machining tools.

Advantageously, the system according to the invention can comprise a control and supply unit which is installed in the second section of the supporting frame, the control and supply unit being designed to supply the machining head for machining the workpiece to be machined and to enable its control.

Likewise according to the invention, the work surface can include a plurality of mutually parallel support rods, as well as clamping elements, such as suction cups and the like, for fixing the workpiece to be machined on the working surface, these clamping elements being detachably coupled to the support rods, and stop rods, which are at the bottom Section of the work surface are fixed and on which the edge of the workpiece to be machined rests when it is arranged on the work surface.

Likewise according to the invention, the system can comprise at least one sliding guide, preferably two mutually parallel sliding guides, the at least one sliding guide being fastened to the supporting frame, and the processing bridge can include lateral sliding shoes which can engage with the at least one sliding guide.

[0024] According to the invention, the at least one sliding guide can advantageously be formed on both of the first and second sections mentioned.

Patent Office are movable and equipped with means for removing and handling the workpieces P to be machined.

The unloading area 9, like the loading area 8, includes a trailer 91 of a trailer truck onto which the workpieces P machined by the processing system 1 can be loaded by means of overhead traveling crane 7.

The magazine station 10 is realized by means of a plurality of inclined frames 101, the structure of which is similar to that of the support frame 2 of the processing system 1.

The functioning of the production line L described above corresponds to the sequence described below.

When a trailer 81 loaded with workpieces P to be machined is brought into the vicinity of the production line L, the gripping unit 73 of the overhead crane 7 removes the workpieces P to be machined, which are wooden walls in the case considered here, and places them on the frame 101, which can also be arranged on suitable trailers so that they are movable, as shown in FIGS. 7 and 8.

Subsequently, with reference to FIG. 9, it can be seen how the gripping unit 73 of the overhead crane 7 places a workpiece P to be machined on the machining system 1.

In this position, the machining bridge 3 moves along the guides 5 and thus enables the machining head 31 to machine the workpiece P.

Subsequently, the now machined workpiece P is reloaded onto the trailer 91 of a truck and possibly stacked on other machined workpieces P to be subsequently transported.

An advantage of the machining system according to the invention is that it enables the machining of workpieces P with large dimensions and surfaces even in a smaller space compared to the systems according to the prior art.

Another advantage of the system according to the invention is that it enables the modular installation of a processing line and thus allows a high degree of adaptability of the system in terms of dimensions and layout of the work area.

The processing system according to the invention also has the advantage that it is modular and removable, so that it can be easily transported using common means of transport, such as trucks.

[0085] This invention has been described in an illustrative but not restrictive manner in the preferred embodiments. However, industry experts may make variations and / or changes, all of which fall within the scope of protection as defined in the appended claims.
