Description

Procedure and machining center for process work pieces in the form of plates.

The present invention relates to a procedure and to a machining center to process parts of wood work, wood-like materials, materials wood, plastic or similar substitutes, in the form of irons

- with at least two machining areas for work pieces that are configured with devices clamping for work pieces,

- as well as with at least one machining unit which is housed in a scrollable way, and supports at least one working spindle to which machining tools can be attached and / or machining modules.

Centers have been known for a long time machining of this type as portal or davit constructions in the most different embodiments.

In portal constructions (see, for example, document DE 10026069) the machining areas are covered through a part that runs horizontally from the construction of portal.

In davit constructions, an arm in Cantilever covers the machining areas.

By an area of machining each one has to be understood type of machine support support on which they can deposit the work pieces in the form of an iron and can be processed in any way. In this context they know each other usual table constructions, called console tables or alignment or also combinations of these constructions of table.

To perform the machining operations, the Work pieces should be fixed on the machining areas of still way. For this, clamping devices are used that mechanical or pneumatic way keep the work pieces on The table constructions. In this context, devices are known mechanical, such as fasteners, called tightening tensioners, or pneumatic devices, called suction tensioners or similar devices, as well as combinations thereof.

With ways of proceeding and machining centers of Known type work pieces can be completely processed.  In this regard, by way of preparation a rough cut manufactured in a separate previous work operation is held over the corresponding machining zone, and then through the machining unit using machining tools or machining modules inserted by a loader the desired machining

The arrangement and restraint of the cuts in gross over the machining area is done most of the time manually by an operator who, after finishing the machining, also again manually, release the work pieces of the machining area and deposits them in an intermediate warehouse.

The raw cuts are extracted most of the time through an installation of cutting an iron with the help of an optimization program (called nesting , nesting).

The employment of centers of specially designed machining instead of an installation of conventional cutting and through these manufacture the cuts in gross required by dividing the plates. Also in similar cases, the plates to be divided are arranged manually in specially designed machining centers and the raw cuts created, after performing the operation of division are also fed manually to the machining center connected downstream in the machining chain for machining final.

Therefore, the known ways of proceeding have in common the fact that, in the corresponding machining centers, although special work steps can always be carried out, also variable in the case of different work pieces, the so-called handling (feed, hold, release and deposit) must always be done manually. Also so far, very different machining operations are carried out, such as the manufacture of raw cuttings and the complete subsequent machining in machining centers configured exclusively for it, that is, the necessary processes are distributed in several machines .

In addition, EP 0 830 922 A2 gives knowing a device according to the preamble of the claim 5.

The objective of the present invention is to improve a procedure as well as a machining center of the type described, so that the handling works can be reduced as extensively as possible for the operator and universal use is also possible in the sense of machining operations very
different.

This objective is solved according to the invention. through a procedure with the characteristics of the claim 1.

If it is connected to the first machining zone upstream a plate stacking area, and at the second or last zone of machining a deposit zone is connected, according to a perfection of the invention the steps of the claim 2.

Fundamentally, the joint movement of the machining unit and the gripping device coupled with it It can be done on any axis. However, it is advantageous when the joint movement of the machining unit and the device of grip coupled with it is performed on an X axis, and the movement of the gripping device and the machining unit on a Y axis They are independent of each other.

The objective is also solved with a machining center with the features of the claim 5.

If in this case it is a center of machining in which, seen in the machining direction, to the first machining zone is connected upstream an area of stacking of plates, and to the second or last machining zone a deposit zone is connected downstream, the objective raised is solved with the characteristics of the claims 5 and 6.

By configuring the center of machining according to the invention a handling system is created integrated into the machine that considerably expands the functionality of such a machining center and frees the operator of a plurality of equipment and management tasks work pieces.

The functionality of a machining center configured according to the invention is extended because for the unit of machining a control device is provided that has both a division program as well as a machining program, and for the gripping device is provided a handling device that can to be programmed

In the event that due to the system of integrated manipulation in the machine can give up the use of several machining centers oriented in each case so special to a manufacturing process, in addition to a greater productivity necessarily produces an investment volume less and a smaller space demand.

Fundamentally, the machining unit and the grip device can be arranged in any way in the machining center However it is advantageous when the unit of machining and the gripping device are housed in a beam of guided that runs substantially horizontally and can scroll horizontally transversely to its extension address

The gripping device may be housed in so that you can scroll in the guide beam in Any suitable way. However, a configuration Especially advantageous occurs when the machining unit it is housed so that it can move reciprocating on one side, and the gripping device on the other side of the guide beam.

Depending on the type of work pieces that are going to processed, the gripping device can be configured of the more different ways. Thus, the gripping device may present mechanical devices, such as lifting jaws, lifting lugs or lifting slats. However it is advantageous to use in the predominant application cases pneumatic devices, such as siphons or suction sleepers, and that these allow very careful handling also on surfaces sensitive

In a preferred machining center, conceived as a davit construction, the guide beam configured as a cantilever arm extends in the Y direction, the processing unit being housed on one side and the gripping device on its other side. so that they can move in each case in the Y direction. In this preferred embodiment, the cantilever arm is guided in the X direction so that it can move along a longitudinally extended machine base. In the case of such a machine concept, it is convenient to arrange a stacking area along the machine base on the feed side, then a first machining zone, following the machine same a second zone of
machined and on the exit side a deposit area, located one behind the other in each case in the X direction.

With such an arrangement, through the gripping device according to the invention, the iron to be can be easily extracted from the area of stacking plates and depositing in the first zone of machined and fixed there by means of the clamping device. TO then the machining unit performs the necessary division in raw cuts, which after finishing the division are extracted by middle of the first piece piece by piece gripping device of machining and are deposited in the second machining zone. In these raw cuts are then made after fixing the called complete machining through the machining unit. Once the complete machining is done, the gripping device receives the finished work piece again and deposits it in the storage area for subsequent transport or for machining later.

Next, for additional explanation and a better understanding is described and explains in more detail a exemplary embodiment of the invention with reference to the figure attached.

The attached figure shows an example of preferred embodiment of a machining center for processing parts  working in the form of plates in a top view that is Very simplified and limited to the essential.

The figure shows a machine base 1 longitudinally extended, on which some are arranged behind others an area of stacking plates 2 (seen from left to right), a first machining zone 3, a second machining zone 4 as well as a deposit zone 5.

Machine base 1 can be configured also in such a way that it only supports the first zone of machining 3 and the second machining zone 4, while the zone of stacking plates 2 and the storage area 5 are arranged as separate areas next to the base machine 1.

Machine base 1 extends (as shown the arrow on the first machining zone 3) in the X direction from the machining center.

On the upper side in the figure, the machine of base 1 is configured with a guide that also extends in the X direction, in which it is driven so that it can move in the X direction through a carriage a column 6 that extends in the vertical direction, which in the area of its end upper supports a guiding beam 7 that runs horizontally and in the Y direction that covers the machine base and forms an arm in cantilever Therefore, in the preferred embodiment example represented is a so-called construction of davit.

Guiding beam 7 has guides on each side that run in the Y direction (not shown). These guides they support on the left side of the figure a machining unit 8 and on the right side of the figure a gripping device 9. Both the machining unit 8 as well as the gripping device 9 can move reciprocating in the Y direction in the guide correspondent. The guide beam 7 with the one machining unit 8 and the gripping device 9 can in turn move along the column 6 in the X direction along machine base 1 a Through the car The guide that runs in the X direction along of the machine base, the carriage arranged on it, column 6 and the guide beam 7 form a displacement device for the machining unit 8 and the gripping device 9.

On the guide beam 7, in the area of the column 6 a saucer magazine 10 is arranged from which a machining spindle (not shown) of the machining unit 8 can extract the machining tools or machining modules necessary for the corresponding machining operation in the so - called pick-up procedure and can be deposited again after the machining.

In the present embodiment, the first machining zone 3 is configured as a table of alignment and the second machining zone 4 is configured as called console table.

The operating mode of the center of machining shown in the figure, which works according to the Procedure according to the invention is as follows.

In a previous work operation they have transported plates 12 from the direction of arrow 11 towards the plate stacking area 2 and have been deposited there.

Depending on the scope of the guide beam 7, the plates 12 rise from the stack of plates well manually or by means of the gripping device 9 and placed on the first machining zone 3 and there they are set through clamping devices (not shown).

Then the plate 12 is divided by the machining unit 8 in the necessary number of cuts in stupid. During this division operation, the gripping device 9 is in the rest position.

After the division into raw cuts, the gripping device 9 comprises a raw cutout and what transports to the second machining zone 4. In this phase, the machining unit 8 is in its resting position.

As soon as the raw trim is set on the second machining zone 4 by means of devices clamping (not shown) complete machining is performed through the machining unit 8. In this phase the device grip 9 is in its resting position. The collection of a piece in gross through the gripping device, the deposit on the second machining zone 4 as well as complete machining to continuation of the same continue through the machining unit 8 until all the raw cuts found in the first machining zone 3 have undergone a machining complete in the second machining zone 4, that is to say processed.

If you have finished the complete machining, the gripping device 9 picks up the finished work piece and the deposit in the deposit area 5. From there, the work piece it is extracted in the direction of arrow 13 or fed to another machining
