专利说明:

This invention relates to a device for straightening plate edges.
In particular, this invention falls into the category of devices for straightening the edges of boards of wood material whose side surfaces are coated with a surface coating.
With the device according to the invention, it is possible to better perform the edges and to more precisely connect the edge bands at the edges of the plate.
In the processing of surface coated panels, the edges of a semi-finished panel are nowadays milled to define the dimensions and geometry desired for the panel.
The semi-finished plate has an internal body, on the two larger side surfaces with a
Surface coating is coated, which thus leaves the edges of the internal body.
The internal body is generally made of wood material, e.g. Plywood or MDF (medium density fiberboard).
The surface coating consists, for example, of melamine paper.
After milling the edges of the plate, it is edged by gluing an edge band, generally made of the same material as the surface coating, to the edge of the plate.
Milling the edges of the semi-finish panel often results in errors in the connection of the edge band to the side edges of the surface coatings, which are generally due to micro-cracks and inaccuracies in the shaping of the edge of the surface coating.
These defects can cause optical defects and locations where moisture easily penetrates the plate.
Nowadays, tensioning is widespread in order to reduce the amount of sizing material for fixing the edge band at the edges.
This trend is contrary to the need to compensate for the effect of said defects by means of the sealing by the glue material.
This invention is based on the problem of allowing a low use of glue and still guarantee an effective and secure sealing of the edge bands on the surface coatings of the plate.
The main object of this invention is to provide a device for straightening plate edges, which offers a solution to this problem and overcomes the stated disadvantages of the conventional devices described above.
Within the scope of this objective, an object of this invention is to provide a device for straightening plate edges which allows for the use of less glue to confine a plate while still guaranteeing a reliable seal.
A further purpose of this invention is to provide a device for straightening plate edges which enables the prevention of the formation of defects at the edges of the surface coatings of a plate to be trimmed.
This object, as well as these and other purposes, which will become more apparent from the following description, are achieved by a device for straightening plate edges according to the appended claim 1.
Detailed features of a device for straightening plate edges according to the invention are set forth in the corresponding dependent claims.
Further features and advantages of the invention will be more clearly illustrated in the following description of a preferred embodiment by no means exclusive of a device according to the invention for straightening plate edges with reference to the accompanying drawings. FIG. 1 is a perspective view of a plate edge straightening device with some parts removed to better show others; - Figure 2 shows the device of Figure 1 in plan view.
With particular reference to the aforesaid figures, reference numeral 10 generally designates a device for straightening the edge 16 of a panel 12 comprising a body of wood material, the two larger side surfaces 12, 12b of which are each provided with a respective one
Surface coating 13a, 13b, which preferably consists of melamine paper coated.
The device 10 comprises a holder 14, which defines a bearing surface for the plate 12, and a milling unit 15.
The device 10 is designed so that the milling unit 15 interacts with a side edge 16 of the plate 12 to machine it when the plate 12 is attached to the holder 14.
The milling unit 15 comprises two milling tools 17, 18, which are arranged so that they at the same time the edge 16 of a plate 12, which is fixed in use on the holder 14, edit.
The apparatus 10 according to the invention has a special feature in that it comprises a finishing tool 19 which is designed to perform finer operations than the milling tools 17, 18 and is positioned so that the finishing tool 19 at least with the edges 20a, 20b of the surface coatings 13a, 13b which cover the edges 16a, 16b of the edge 16 interfere when the milling tools 17, 18 interfere with the edge 16 of the plate 12 in use.
In this text, it is to be understood that one treatment is finer than another if less material is removed from that body with the same interaction of the tool that it makes with the machined body, i. h., that
Tool has less interference with the body to be machined.
The finishing tool 19 is preferably arranged between the two milling tools 17, 18.
The milling tools 17, 18 preferably have opposite directions of rotation, so that the edge 16 of the plate 12 is effectively processed.
The fine machining tool 19 is advantageously arranged closer to a first 17 than to the second 18 of the milling tools 17, 18 and has a direction of rotation which is opposite to that of the first milling tool 17.
Advantageously, the first milling tool 17 and the finishing tool 19 are connected by means of drive means which are suitable for synchronizing their rotation.
It has been found that it is preferable that the drive means comprise a toothed belt 21 to optimize the transmission of torque.
Preferably, at least one of the milling tools 17, 18 is designed to straighten the edge 16 of a plate 12.
In particular, the second milling tool 18 is designed to straighten the edge 16 of a plate 12.
In a preferred, but not exclusive embodiment, the finishing tool 19 is designed to perform grinding and preferably has a grinding surface suitable for machining the edges 20a, 20b of the surface coatings 13a, 13b, having a grain size of 180 μm up to 15 pm, for milling machines, which are preferably diamond cutters.
Advantageously, the milling tools 17 and 18 and the finishing tool 19 have a substantially cylindrical structure, the side wall being suitable for machining the plate 12, and advantageously having axes aligned parallel to one another.
The invention thus conceived is subject to numerous changes and variants, all of which fall within the scope of the inventive concept according to the appended claims.
Furthermore, all the details of the invention may be replaced by technically equivalent elements.
In the practice of the invention, the materials used as well as the respective shapes and sizes can be varied as desired according to the respective requirements and the state of the art.
Insofar as the structural and technical features listed in the appended claims follow numerals or numbers, these reference numerals or numbers are inserted only for a better understanding of the claims and therefore have no limiting effect on the design of each element, by way of illustration only The reference numbers or numbers are marked.
