Detailed description

With reference to the above-mentioned figures, a machining center is indicated overall with 1, in particular for machining material (milling, drilling, flanging, etc.), such as for machining workpieces Wood, wood-based materials or materials comparable to wood. The machining center 1 can for example comprise a numerically controlled machining center. The machining center 1 can in particular comprise three or more working axes.

The machining center can in particular have at least one base 2 comprise which, as in this example, can have holding means to hold at least one workpiece to be machined. These holding means can in particular comprise at least one holding surface, as in this special case, for example, a horizontal holding surface. The holding means can in particular have one or more supporting rods 3 include, for example, with one or more fasteners 4th are equipped for the workpiece.

The machining center 1 can in particular at least one cross member movably mounted on a first axis X of the machining center 5 include. The cross member 5 can be part of a movable portal frame which is operatively connected to the holding means for the workpiece (s) to be machined. The cross member 5 can, as in this example, be arranged at least partially above the holding surface. The cross member 2 can in particular comprise an elongated element which is elongated in the direction of a second axis Y of the machining center. The second axis Y can be perpendicular to the first axis X, as in this example. The means of moving the cross member 2 can in particular be means of movement of the known type and are therefore not described in more detail.

In particular, the machining center can have at least one work unit 6th include that is on the cross member 5 is located and can be moved. The unit of work 6th can for example be movable on said second axis Y of the machining center. The unit of work 6th can in particular comprise a tool carrier head (with exchangeable tool) that can carry out various (cutting) machining processes such as milling, drilling, flanging, etc.

The machining center 1 can in particular at least one tool magazine 7th include. The tool magazine 7th can in particular be movable in a direction lying parallel to the first axis X of the machining center. The tool magazine 7th can in particular be moved with a first (rectilinear) movement, which together with the (rectilinear) movement of the cross member 5 can be done on the first axis X. In particular, the tool magazine 7th as in the present case in conjunction with the cross member 5 be agile. The tool magazine 7th can be attached at least partially over the holding surface for the workpiece.

The machining center 1 can in particular at least one protective cover 8th (for the safety of the operating personnel) include, in particular for receiving (at least partially, for example laterally, on all sides or at least part of the sides) of the work unit 6th is designed over a part or the entire possible run length in the direction of the second axis Y. The protective cover 8th can in particular together with the cross member 5 be movable, for example in the direction of the first axis X. The protective cover 8th can hold the entire tool magazine 7th or a part thereof.

The protective cover 8th can in particular comprise at least one protective housing, for example made of plastic, in particular made of a material that is used for the production of protective devices in machining centers of the known type. The protective cover 8th is constructed and installed so that it has at least part (at least laterally) of both the working unit 6th in their movement on the second Y axis as well as the tool magazine 7th that goes together with the cross member 5 can move, envelops and / or encloses in order to ensure the safety and integrity of the operating personnel responsible for the machining center. The protective cover 8th can be attached at least partially over the holding surface of the workpiece.

The tool magazine 7th can in particular comprise at least some of the tool holders that are in one of the cross members 5 opposite row are attached (where with opposite is meant in the direction of the first axis X). This row with tool holders can, for example, be parallel to the longitudinal direction of the cross member 5 lie. The row with tool holders can, for example, lie parallel to the second axis Y of the machining center.

The tool magazine 7th can as in the present example at least one related to the unit of work 6th movable part with the possibility of a second movement (separate from the first movement mentioned above), with which it can take at least one distal (retracted) rest position in which it is relatively far from the working unit 6th is located, and can take at least one proximal (advanced) position for the tool change, in which it is relatively close to the working unit 6th is located. The second movement of the moving part of the magazine 7th can in particular at least one linear movement, for example a ( vertical) transverse movement to the longitudinal direction of said row with tool holders.

The moving part of the magazine 7th can in particular with guide means 9 be connected, for example, to linear guide means, in particular to (linear) sliding guide means. The guide means 9 can be attached to a holder (in particular in the form of a plate as in the present example) that holds the tool magazine 7th carries and (mechanically, for example firmly connected, in particular with bar-shaped means 10 ) with the cross member 5 can be connected.

The moving part of the magazine 7th can in particular via the control of (from the motor means of the cross member 5 separate and / or independent) motor means are moved between a distal and a proximal position. The motor means of the movable part of the magazine can in particular comprise one or more linear drives. These motor means can comprise motor means with any type of drive, for example electrical, pneumatic, hydraulic etc. These motor means can be joined together (permanently connected) with a first movement of the cross member 5 be movable in a direction of movement parallel to the first axis X. These movements, the first and the second, which are separate and independent of each other (the first movement comprising the working movement along the first axis X of the machining center, while the second movement the relative movement of the magazine 7th regarding the working group 5 between the rest position and the position for the tool change), can in particular lie parallel to one another.

As I said, the protective and safety cover 8th together with the cross member 5 (first working movement) be movable along the first axis X, mainly due to the fact that the protective cover 8th on the cross member 5 is attached. The tool magazine 7th can together (firmly connected) with the cross member 5 be movable, especially due to the fact that the tool magazine 7th on the cross member 5 attached or firmly connected to it. It is possible, as in this example, to use the web-shaped means 10 , for example, to arrange at least one support arm so that they protrude from the cross member in a cantilever manner, one end on the cross member 5 is attached and the opposite end to the tool magazine 7th is appropriate.

In another example, not shown, the tool magazine 7th together with the cross member 5 be movable due to the fact that the tool magazine 7th is equipped with (own and separate) motor means configured to operate the tool magazine 7th together with the cross member 5 move along the first axis X, the motor means of the tool magazine 7th and the motor means of the cross member 5 be controlled via (programmable electronic) control means which move the two elements in a coordinated manner (for example simultaneously and at the same speed).

The protective cover 8th can be a first part as in this example 8a and a second part 8b include, both of which are (firmly) connected to each other. The first part 8a can run in the direction of the second axis Y to the working unit 6th at least partially or completely to enclose them in their movement along the second axis Y. The second part 8b can be like in this example from the first part 8a protrude, in particular in the direction of the first axis X, around the tool magazine 7th secure to enclose. The second part 8b can, as in this example, consist of an extension consisting of an (upper) area of the first part 8a steps out. The first part 8a can, as in this example, comprise wall-like means which are open at the bottom and the working unit 6th and / or the cross member 5 surround. The second part 8b may, as in this example, comprise wall-like means on one side of the wall-like means of the first part 8a step out and can be dome-shaped.

The unit of work 6th could for example have shuttle devices (e.g. of the known type) configured for tool change. The tool change can be carried out in particular when the movable part of the tool magazine 7th is in the proximal (advanced) position for tool change. When the unit of work 6th machined the workpiece, the moving part of the tool magazine 7th are in a distal (retracted) resting position.

In this example the tool magazine includes 7th a single (fixed, ie non-sliding) row of tool holders. In other examples, not shown, it is possible to provide a tool magazine of a different type, for example a magazine with several rows of tool holders (for example one row above the other) or a movable magazine in which the various tool holders can be displaced (for example along an endless one Sliding ring) or a magazine with at least one rotating carousel etc.

The arrangement of at least one tool magazine 7th , which together (in fixed connection or coordinated) with the support means (crossbeams 5 ) of the unit of work 6th is movable, makes it possible to reduce the tool change times, in particular by reducing the distance between the working unit 6th and magazine 7th . also allows the magazine to be arranged 7th inside a protective cover 8th , especially a protective cover 8th that includes at least a part that is the unit of work 6th safely protects, a machining center with relatively small dimensions that can guarantee the integrity of the operating personnel.
