Description

Processing device and processing method for

Machining a workpiece

Technical field

The invention relates to a processing device which is suitable for processing a, in particular plate-shaped, workpiece which preferably comprises wood, wood-based material, plastic or the like, at least in sections. The invention also relates to a machining method.

State of the art

In the field of machining devices, machining devices for machining plate-shaped workpieces are known which have an independent drilling location for lateral machining. Therefore, the workpieces to be machined are moved to an independent drilling station, which is either raised or designed as a console table, for example. In this way, the workpieces to be processed can be processed by drilling or other processing on an independent drilling station, which cannot be carried out with workpieces lying close together.

The independent drilling site is located outside the processing table, where there is already a plate-shaped Workpiece has been processed. The machining table on which a plate-shaped workpiece is machined cannot be used for further lateral machining in conventional machining devices.

Devices are known with which the workpieces to be processed are milled from a plate-shaped starting workpiece and these are thus essentially directly adjacent to one another on the table. Thus, no lateral or horizontal machining of the workpieces on the table of the first machining device is possible without removing residual raw material areas or filling parts.

In further processing devices, the workpieces to be processed can be lowered or raised on a console table for lateral processing so that they are no longer in one plane with the processing table.

In other processing devices, a plate-shaped workpiece is not processed in such a way that the workpieces to be processed are essentially directly adjacent to one another. This creates a larger area with residual raw materials from the plate-shaped workpiece. These residual raw material areas of the plate-shaped workpiece are then additionally processed. This additional processing of the residual raw material areas allows pockets to be milled in the residual raw material area, so that a drilling tool for the side machining of the workpiece, the narrow surface, can then be inserted into the pocket and side machining can take place. This generates a large proportion of residual raw material.

Alternatively, the remaining raw material areas that are present around the workpieces to be machined can also be removed manually, if there is a sufficiently large distance so that a machining tool can handle a workpiece can edit laterally. In addition, the size and arrangement of the processing tools are selected so that they can be inserted into the area of the milled pocket so that the narrow surface can be processed.

Subject of the invention

The aim of the invention is to provide a device for machining a workpiece and a machining method with which the machining process is simplified with an expanded spectrum.

One idea of the invention is to provide a processing device which allows processing of at least one narrow surface of a workpiece, with the lateral processing taking place within a table or in one or more processing areas that are within a table on which a first processing of a plate-shaped Workpiece is done.

The subject matter of claim 1 provides a corresponding machining device for machining a workpiece. Further preferred embodiments are set out in the dependent claims. The invention also relates to a method.

According to the invention, the processing device has: a table for receiving a plate-shaped initial workpiece, a first processing device for dividing the initial workpiece provided on the table, a transport device for transporting at least one partial workpiece created from the initial workpiece to a further position on the table, wherein the first processing device or a second processing device of the processing device for this purpose is set up to process the partial workpiece located in the further position on the narrow surface side.

A previous machining of the starting workpiece may already have taken place on the table. No further processing table is therefore necessary. The narrow surface of the partial workpiece to be machined is freely accessible.

By processing the partial workpiece by a first processing device or a second processing device on the table, on which the initial workpiece is also processed by the first processing device, components and devices of the processing device can be saved.

For example, the narrow side of the partial workpiece can be machined by means of the first machining device. In this case, the processing device only has the first processing device. Otherwise, the processing device can have the first processing device and the second processing device.

Such a use of only one table for several machining steps has the advantage that a plate-shaped workpiece can be machined easily and the machining device has fewer machining components. In addition, it is ensured that the partial workpieces lying directly against one another are machined from the first machining device on the narrow surface. This simplifies the machining of plate-shaped workpieces. Furthermore, residual raw materials can be saved, since the plate-shaped starting workpiece can be effectively processed and the proportion of residual raw materials is kept as small as possible. In addition, the machining device according to the invention enables different machining tools, for example drills and milling cutters, to be used and no restrictions on the size of machining tools are necessary.

According to one embodiment, the transport device of the processing device is set up to carry out a movement in at least three spatial directions, preferably in a rotational and / or translational direction.

By moving the transport device in the three spatial directions, different shapes of workpieces can be transported. In addition, the workpiece to be machined can be positioned on the table in a predefined orientation.

In a preferred embodiment, the processing device has a second processing device which is attached to the side of the table; the second processing device is preferably attached to the processing device in a stationary manner.

By attaching the second machining device to the side, the second machining of the plate-shaped workpiece can be carried out more easily, and the second machining device can be simplified. Furthermore, the number of processing tools that can be used increases.

In a preferred embodiment, the machining device can also have a spindle unit, at least one of the machining devices being attachable to the spindle unit. If the first processing device is used, which is set up for dividing the initial workpiece provided on the table and for processing the narrow surface, another processing device can be exchanged for further processing. It is also possible to interchange processing devices, in particular a first processing device for dividing the initial workpiece provided on the table and a second processing device which is set up to process the partial workpiece located in the further position on the narrow surface side. The spindle unit can thus be used by the first and second machining devices. When the type of processing is changed, one of the processing devices can be exchanged for the other processing device.

According to a further embodiment, the machining device comprises a plurality of spindle units. The machining devices can each be attached to one of the spindle units, or the machining devices can be exchanged in one of the spindle units.

According to a further embodiment, the first processing device contains processing tools which have a different orientation or can be brought into a different orientation.

According to a further embodiment, the second processing device contains processing tools which have a different orientation or can be brought into a different orientation.

The advantage of the machining tools is that a large number of conventional tools and special tools can be used for lateral machining. The second machining device can thus be equipped with a large number of tools, so that various machining operations can be carried out on the partial workpiece. Due to the variable orientation of the Processing tools, various processing of the narrow surface are possible.

In a preferred embodiment, the table has a first processing area and a second processing area, preferably a drilling station.

This saves a further, independent, second processing table and the partial workpiece is only moved within one table.

The partial workpiece can preferably be processed on at least two exposed narrow surfaces by the first processing device.

The partial workpiece can preferably be machined on at least two exposed narrow surfaces by the second machining device.

By processing the narrow surface by the first processing device or the second

Machining device, a plate-shaped workpiece can be machined within a machining device and within a table on the wide surface and narrow surface. Components of a

Machining device can be saved and simplified.

According to a further aspect, the first machining device processes a plate-shaped starting workpiece by milling, for example, the resulting partial workpieces essentially lying directly against one another, so that several partial workpieces to be machined are created from the plate-shaped starting workpiece by the first machining device. This is to ensure that the partial workpieces to be processed are produced essentially directly next to one another from the plate-shaped starting workpiece in order to minimize residual raw materials as far as possible.

The machining method, which can be carried out, for example, with a machining device according to one or more of the aforementioned aspects, comprises the following steps: removing a machine to be machined

Partial workpiece from a divided, plate-shaped starting workpiece, which is arranged on a table, transporting the partial workpiece to be processed to a further position on the table so that at least one narrow surface of the partial workpiece is accessible, and processing of the partial workpiece located in the further position on the Narrow surface. It is preferred that the steps be carried out in the order listed.

In this way, an initial workpiece can be easily attached to the wide and narrow surfaces within a table by the first machining device or by the first

Processing device and a second

Processing device to be processed. Furthermore, the machining method provides a simple method which enables machining of the wide surface and narrow surface of a plate-shaped partial workpiece.

In a further embodiment of the machining method, the transported partial workpiece is machined on the narrow surface by machining tools of at least one machining device, which preferably have a different orientation or can be brought into a different orientation and can be moved. At least two exposed narrow surfaces can preferably be machined by at least one machining device, preferably simultaneously. By transporting a partial workpiece so that at least one narrow surface is accessible for machining, it is ensured that a large number of tools with different orientations can be used to machine the narrow surface. Furthermore, due to the mobility of the machining tools, different bores or grooves, for example, with different orientations and diameters can be produced.

In a further embodiment of the machining method, a plate-shaped starting workpiece is divided, for example by milling, the partial workpieces to be machined from the plate-shaped starting workpiece essentially lying against one another on the table.

This reduces the residual material and raw materials of the plate-shaped starting workpiece can be saved, so that the raw materials can be processed more sustainably. Furthermore, a processing step is saved that, for example, residual parts or the residual material have to be removed from the processing device before a lateral processing or processing of the narrow surface can take place.

In addition, at least one

Machining device any form of plate-shaped partial workpieces can be machined on the narrow surface.

In a further modification, the machining of the plate-shaped starting workpiece by the first machining device can take place in parallel with machining of the partial workpiece or at least one partial workpiece in the second machining device. In another modification, the plate-shaped starting workpiece is machined by the first

Machining device leading, that is, before the machining of the partial workpieces by the second machining device.

In a further embodiment, the method comprises the step of: moving the machined partial workpiece to a

Discharge device or to another

Working area of the table. The partial workpiece can thus be fed to further processing. Furthermore, the machined partial workpiece can preferably be returned to its original position. This makes it possible for all the machined partial workpieces of the plate-shaped workpiece to be pushed out of the machining device or removed in a simple manner.

Furthermore, it can be provided that the partial workpiece is brought into a different orientation during transport to the further position on the table.

Detailed description of the preferred embodiments

Preferred embodiments of the invention are described with reference to the figures. Although the embodiments are to be understood as exemplary and not restrictive, Individual features of the embodiments can also be used to characterize the invention. Furthermore, modifications of the embodiment described below can each be individually combined with one another to form further embodiments of the invention.

The machining device 100 is set up to machine a plate-shaped partial workpiece 10 at least on the narrow surface. Plate-shaped workpieces 10, a starting workpiece and partial workpieces, have a broad surface and a narrow surface, the broad surface defining the larger surface of the plate-shaped workpiece and the narrow surface defining the smaller surface of the plate-shaped workpiece. The plate-shaped workpieces can consist of various materials, preferably at least in sections of wood, wood-based materials, plastics or the like. Furthermore, the plate-shaped workpieces can have different material thicknesses or material thicknesses.

The processing device 100 comprises a table 4, a transport device, a first processing device (not shown) and a second processing device 20.

The table 4 of the processing device 100 can, for example, be a flat table. The table 4 is used for all processing operations of the processing devices 100, so that no further table is necessary for processing the narrow surface. In addition, the table 4 is characterized in that at least one processing area is present within the table 4, so that there is no offset between the one or more processing areas of a table 4. The transport device is designed to transport a partial workpiece 10 to be processed. The partial workpiece 10 can be transported, for example, by a gripper device, in particular a suction gripper, or the transport device can transport the workpiece, for example, by a conveyor belt, a conveyor chain or a conveyor belt. According to a modification, the transport device can additionally be set up to move the partial workpiece 10 by lifting or picking it up.

The first processing device processes a plate-shaped starting workpiece, for example by milling, so that several partial workpieces 10 are produced which are essentially milled directly against one another from the plate-shaped starting workpiece. The already divided workpiece is shown in the figures. The partial workpieces 10 to be processed are thus present in a composite on the table 4 and are possibly partially surrounded by residual pieces. Remnants or residual raw materials are parts of the plate-shaped starting workpiece which are no longer used and are, for example, recycled.

The plate-shaped starting workpiece and the partial workpieces 10 to be processed are located on the table 4 of the processing device 100 during each processing.

The second processing device 20 of the processing device is set up in such a way that at least one narrow surface of a partial workpiece or plate-shaped partial workpiece 10 can be processed by processing tools. According to a modification of the embodiment, the narrow side of the workpiece part 10 can be machined by means of the first machining device instead of the second machining device 20 or in addition thereto. Since at least one narrow surface must be freely accessible for the processing tools for the processing of the narrow surface by the second processing device 20, the partial workpiece 10 to be processed is moved by a transport device within the table 4 and placed on the table 4 in such a way that at least one, preferably two , Narrow surface of the transported partial workpiece 10B is exposed. With exposed or accessible is meant that a machining tool of the second machining device 20 can contact the narrow surface of the partial workpiece 10B and machining can thus take place. Not exposed or not accessible, however, means that the processing tool of the second processing device 20 cannot come into direct contact with the narrow surface.

With the second processing device 20, all conventional processing of the narrow surfaces on the plate-shaped partial workpiece 10B to be processed can be carried out. The processing of the narrow surface is done by at least one processing tool. A machining tool can have, for example, a drill, milling cutter, saw, or drill spindle with a drill head. By means of the at least one drilling tool, the narrow surface can be machined in such a way that, for example, holes are made with different tools, pocket millings are made, grooves or miter cuts are made. Optionally, the machining tool can produce a hole, with a dowel then being inserted into the hole. The bores on the narrow surface can preferably have different bore diameters.

The first machining device and the second machining device 20 each have a machining tool. The processing tools are attached to the respective processing device, for example exchangeable. This allows the respective Machining device, if necessary, machine a workpiece using various machining tools.

By machining the plate-shaped partial workpiece 10B within a table 4, larger workpieces can occasionally also be machined.

In the machining method according to the invention, a plate-shaped workpiece is machined in several steps. In the first step, a plate-shaped starting workpiece is placed on the table of the processing device 100. The first machining of a plate-shaped starting workpiece by the first machining device takes place in area A of the table. In this case, the plate-shaped starting workpiece is divided into several partial workpieces 10 to be machined in the first machining device, preferably by milling. The partial workpieces 10 to be processed are thus in area A, the division area, of the table 4. Subsequently, a partial workpiece 10 to be processed is transported from area A of table 4 by the transport device into area B, the processing area.

In area B, the first processing device or second processing device 20 processes the transported partial workpiece 10B. As previously described, area B can also be defined, for example, as a drilling site which is inside table 4. The partial workpiece 10 to be processed is thus transported by the transport device within the table 4 of the processing device 100. The partial workpiece 10 to be machined is deposited in the area B of the table 4 in such a way that at least one narrow surface of the partial workpiece 10B is freely accessible.

In area B of the table 4, the workpiece 10B to be machined is passed through the first on the narrow surface Processing device or second processing device 20 processed. The narrow surface is preferably machined in the first machining device or in the second machining device 20 by drilling, for example with different drilling diameters.

In a further embodiment, the partial workpiece 10B to be machined, if a narrow surface has already been machined, can be positioned differently within the area B of the table 4 by the transport device, so that at least one further, unmachined narrow surface of the partial workpiece IOC is freely accessible and again through the first processing device or the second processing device 20 can be processed. This step can be repeated, for example, until all narrow surfaces, for example predefined, have been processed by the first processing device or the second processing device 20.

In a first, preferred embodiment (FIG. 1) the partial workpiece 10B can be rotated by the transport device and placed on an opposite side of the area B of the table 4, where the partial workpiece to be processed was previously positioned. Opposite means the opposite side of the table area B, where the workpiece part 10B was previously placed. At least one further narrow surface of the partial workpiece 10C is thus exposed for lateral machining by the first machining device or the second machining device 20.

In a further embodiment (FIG. 2), the partial workpiece 10B can be shifted laterally by the transport device to an opposite side of the area B of the table 4, which is within the area B compared to the previous position. There is at least one further narrow surface of the partial workpiece IOC for lateral machining by the first machining device or the second machining device 20 free.

When all narrow surfaces of a partial workpiece 10 to be processed have been processed, for example as previously defined, the processed partial workpiece 10 can either be deposited by the transport device on an outfeed device or returned to the original position in area A of the table 4 or on another Area of the table. The original position means that the transport device returns the processed partial workpiece to its original location within the plate-shaped starting workpiece.

In a further step, the transport device can pick up a further partial workpiece to be processed from the area A of the table 4 and have it processed laterally by the first processing device or the second processing device 20 in the area B of the table 4. This process can be repeated until, for example, all partial workpieces to be processed of the plate-shaped starting workpiece, as defined, for example, have been processed on the narrow surface by the first processing device or the second processing device 20.

The processing device 100 can in particular be used in woodworking machines. Furthermore, the processing device 100 according to the invention allows batch sizes from a number of one to be processed.
