    The invention relates to a method for performing a tool change on a processing system, and a processing system with a tool changing device.
    DE102006038500A1 discloses a processing system with a tool magazine. The transport of the machining tools between the machining spindle and the tool magazine takes a long time in such a machining system.
    The object of the present invention was to overcome the disadvantages of the prior art and to provide an apparatus and a method by means of which the set-up times can be kept as short as possible in order to minimize the idle times.
    This object is achieved by a device and a method according to the claims.
    According to the invention, a method for performing a tool change on a processing system is provided. The processing system comprises: at least a first work spindle;
    a tool magazine for storing different machining tools, at least one storage level with a plurality of tool holding stations arranged next to one another being provided in the tool magazine; a tool changing device with at least one first gripping device for changing the machining tool accommodated in the work spindle, wherein the gripping device has at least a first gripping unit and a second gripping unit which are at a gripping unit distance from one another
    2/34
    N2017 / 10500-AT-00 are arranged.
    The process comprises the following process steps:
    - Removing an already used processing tool from the work spindle by means of the first gripping unit;
    - Inserting a machining tool accommodated in the second gripping unit into the work spindle;
    - Moving the gripping device to the tool magazine for receiving a new processing tool from the tool magazine into the gripping device and at the same time placing the processing tool already used from the gripping device into the tool magazine; and at the same time
    - Machining a workpiece using the machining tool accommodated in the work spindle.
    An advantage of the method according to the invention is that the time required to fetch a processing tool from the tool storage can be kept as short as possible. This is particularly advantageous if the machining operations take only a very short time and a new machining tool is required as quickly as possible.
    Furthermore, it can be provided that a second work spindle is arranged next to the first work spindle, the work spindles being arranged parallel to one another and used to hold a processing tool, and that the tool changing device has a second gripping device, the two gripping devices being moved synchronously with one another and simultaneously the operate both work spindles. This means that the two work spindles can be operated synchronously with each other.
    Furthermore, it may be expedient for the machining tools to be arranged in the storage plane in order to accommodate a new machining tool from the tool magazine into the gripping device and at the same time to deposit the machining tool already used from the gripping device into the tool magazine, in such a way that the new machining tool is arranged at a first tool holder location and in the gripper unit distance to
    3/34
    N2017 / 10500-AT-00 first tool holder location, a second tool holder location is free, which serves to deposit the machining tool already used from the gripping device into the tool magazine. The advantage here is that this measure allows the gripping device with the two gripping units and the machining tool accommodated in one gripping unit to be moved to the respective storage unit in order to be able to store the machining tool. The machining tool is guided into the free tool holder space. At the same time, the newly provided machining tool is gripped by means of the still free gripping unit and can thus be guided to the work spindle of the machining system. The current effort to put down the old processing tool and pick up the new processing tool can be kept so low because the gripping device does not have to move to two different positions in the tool magazine, but the old processing tool can be stored in one operation and the new processing tool can be picked up at the same time , The machining tools are positioned in the tool magazine so that the machining steps described are made possible.
    Furthermore, it can be provided that processing tools can be inserted manually in a tool insertion station and can subsequently be picked up by means of a gripping unit. It is advantageous here that machining tools provided for future machining operations can be inserted and can be moved to a free space in the tool magazine by means of the gripping unit.
    In addition, it can be provided that in selected machining processes, in particular in machining processes with a long machining time, during machining of the workpiece, the machining tools stored in the tool magazine are re-sorted by means of the gripping device. The advantage here is that the machining tools can be re-sorted according to the machining steps planned in the future, by one at a time
    4/34
    N2017 / 10500-AT-00 to find free tool holder space next to a machining tool to be exchanged and thus to enable the tool changing process according to the invention.
    In addition, it can be expedient if processing tools which follow those processing tools in the processing sequence by means of which shorter-lasting processing steps are carried out are stored closer to the work spindle than processing tools which follow those processing tools in the processing sequence by means of which longer-lasting processing steps are carried out. This measure can ensure that a quick change-in process is ensured during processing by means of a processing tool with a short processing time, since the gripping device only has to travel short distances. As a result, a new machining tool can be fetched from the tool store even during this short period of time.
    According to a further development, it is possible for machining tools that are used more often to be stored closer to the work spindle than machining tools that are used less often. This measure can ensure that the machining tools with frequent use are guaranteed a quick change-in process, since the gripping device only has to cover short distances.
    Furthermore, it can be expedient if the processing tool already used is removed after removal from the work spindle by means of the gripping device of a measuring device in which wear of the processing tool is detected. The advantage here is that the wear of the machining tool or a possible breakage of the machining tool can be detected by this measure. As a result, a replacement of the processing tool can be requested before the processing tool is stored in the tool magazine, or the processing tool can be stored at a corresponding location where it can be exchanged.

    N2017 / 10500 AT-00
    According to the invention, a processing system is provided, which has the following
    Components include:
    at least a first work spindle and a second work spindle, which are arranged parallel to one another and each serve to receive a processing tool;
    a tool magazine for storing different machining tools, at least one storage level with a plurality of tool holding stations arranged next to one another being provided in the tool magazine; a tool changing device with at least a first gripping device and a second gripping device for changing the machining tools accommodated in the work spindles, the gripping devices each having at least a first gripping unit and a second gripping unit which are arranged at a gripping unit distance from one another.
    The gripping units can be moved between the respective work spindle and the tool magazine.
    An advantage of the machining system according to the invention is that the time required to fetch a machining tool from the tool store can be kept as short as possible. This is particularly advantageous if the machining operations take only a very short time and a new machining tool is required as quickly as possible.
    Furthermore, it can be provided that the distance between two adjacent tool holder locations corresponds to a storage level, the gripping unit distance or a trunk break of the gripping unit distance. In other words, the gripping unit distance is an integral multiple of the distance between two adjacent tool holder locations on a storage level. The advantage here is that a machining tool that has already been used can be stored in the tool store at the same time as this measure, and a machining tool that is intended for future machining steps can be removed from the tool store.
    6/34
    N2017 / 10500 AT-00
    According to a special embodiment, it is possible for a plurality of storage levels to be arranged one above the other in the tool magazine, the distance between two adjacent tool receiving locations being different in the different storage levels. As a result, the different storage levels can be designed to accommodate machining tools of different sizes.
    According to an advantageous development, it can be provided that the gripping devices are mounted on a gripping device carrier so as to be displaceable in the transverse direction.
    In particular, it can be advantageous if the gripping devices can be displaced in the transverse direction by means of a central drive motor and are displaced in relation to one another. The advantage here is that only one drive motor is required to move the gripping devices. The gripping devices can thus be operated synchronously for both work spindles.
    It can also be provided that the gripping devices are mounted on the gripping device carrier so as to be pivotable with respect to a vertical axis. As a result, the gripping devices can remove machining tools from the tool magazine, which are mounted, for example, at an angle of 90 ° to the spindle axis of the work spindle. The possible swivel angle can of course also be greater than 90 °.
    In addition, provision can be made for the gripping device carrier to be mounted in a height-adjustable manner on a height adjustment device. This measure enables different storage levels to be reached in the tool magazine.
    Also advantageous is a configuration according to which it can be provided that the height adjustment device is mounted displaceably by means of a linear guide in a longitudinal direction running parallel to the spindle axis of the work spindle.
    According to a further development, it is possible for the linear guide to be arranged in the center of the processing system.
    7/34
    N2017 / 10500 AT-00
    Furthermore, it can be expedient if a first tool magazine section is formed which is assigned to the first work spindle and a second tool magazine section is formed which is assigned to the second work spindle, the two tool magazine sections being arranged symmetrically with respect to a central plane on the processing system. The advantage here is that the machining tools for the first work spindle and for the second work spindle can be stored in and removed from the tool magazine simultaneously and parallel to one another.
    Furthermore, it can be provided that the tool magazine has two storage systems which are arranged at a distance from one another and each have a plurality of tool holding places arranged one above the other, the height of the storage systems being adjustable relative to one another, so that different pairings of tool holding places can be set. For example, it can be provided that the two storage systems each have a paternoster system with a plurality of tool holder locations. In a further embodiment variant, it can also be provided that the two storage systems each have a linear rail system. Of course, it is provided that each of the work spindles is assigned such a structure of storage systems.
    The features according to the invention are particularly advantageous on processing systems with two work spindles. However, the features also have great advantages for processing systems with only one work spindle.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.
    Each show in a highly simplified, schematic representation:
    Figure 1 is a perspective view of an embodiment of a processing system.

    5 shows a schematic illustration of a third machining step in a tool changing operation;
    Fig. 6 is a schematic representation of a fourth machining step in a tool changing process.
    In the introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, and the disclosures contained in the entire description can be applied analogously to the same parts with the same reference numerals or the same component names. The location information selected in the description, e.g. above, below, to the side, etc., referring to the figure described and illustrated immediately, and if the position is changed, these are to be applied accordingly to the new position.
    1 shows a schematic illustration of a perspective view of an exemplary embodiment of the machining system 1. The machining system 1 is used in particular for machining workpieces, a first work spindle 2 and a second work spindle 3 being formed, in which machining tools 4 can be accommodated. In order to illustrate the essence of the invention, essential components of the processing system 1 are hidden. The first work spindle 2 is indicated schematically. For the sake of clarity, the second work spindle 3 is only indicated by a center line.
    1 shows a tool changing device 5 for changing the processing tools 4 and a tool magazine 6 for receiving the processing tools 4.
    9/34
    N2017 / 10500 AT-00
    The tool magazine 6 is used in particular for providing and storing different machining tools 4 for different machining operations. As can be seen from FIG. 1, it can be provided that the tool magazine 6 has a first tool magazine section 7 and a second tool magazine section 8, which are formed symmetrically with respect to a central plane 9. It is thus provided that the first tool magazine section 7 is assigned to the first work spindle 2 and the second tool magazine section 8 is assigned to the second work spindle 3.
    In the individual tool magazine sections 7, 8, a plurality of storage levels 10, each with a plurality of tool holder locations 11, can be formed. The tool holding places 11 are arranged next to one another in the individual storage levels 10, wherein a distance 12 between two tool holding places 11 arranged next to one another can be of different sizes in different storage levels 10. For example, it can be provided that a storage level 10 is designed to accommodate large machining tools 4, the distance 12 of the individual tool holding locations 11 from one another being twice as large as in a further storage level in which smaller machining tools 4 are accommodated.
    As can also be seen from FIG. 1, the tool changing device 5 has a first gripping device 13 and a second gripping device 14. The first gripping device 13 is used to transfer machining tools 4, which are incorporated in the first tool magazine section 7, to the first work spindle 2. The second gripping device 14 is used to transfer machining tools 4, which are incorporated in the second tool magazine section 8, to the second work spindle 3.
    Since the machining steps of the work spindles 2, 3 take place in parallel or synchronously with one another, it is also provided that the machining tools 4 of the two work spindles 2, 3 are exchanged simultaneously. The same machining tools 4 are thus mounted symmetrically to one another in the first tool magazine section 7 and in the second tool magazine section 8.
    10/34
    N2017 / 10500 AT-00
    As can also be seen from FIG. 1, a first gripping unit 15 and a second gripping unit 16 are formed on both the first gripping device 13 and the second gripping device 14. The first gripping unit 15 and the second gripping unit 16 each serve to remove the machining tool 4 already used from the work spindle 2, 3 or to insert a new machining tool 4 into the work spindle 2, 3.
    Due to the process sequence during the tool change, the processing tool 4 already in use is alternately received once in the first gripping unit 15 and once in the second gripping unit 16. The new machining tool 4 is provided in the other gripping unit 15, 16.
    The two gripping units 15, 16 are arranged at a gripping unit distance 17 from one another. The gripping unit distance 17 and the distance 12 between two adjacent tool holder locations 11 can be the same size, for example. In addition, it is also conceivable that the gripping unit distance 17 corresponds to an integer multiple of the distance 12 between two adjacent tool holder locations 11. In other words, the distance 12 between two adjacent tool holder locations 11 is a fraction of the gripping unit distance 17.
    The first gripping device 13 and the second gripping device 14 are arranged on a gripping device carrier 18, which is described in more detail in FIG. 2 or is explained on the basis of the illustration in FIG. 2. The two gripping devices 13, 14 can be displaced in the transverse direction 19 relative to one another or relative to the gripping device carrier 18. This can preferably be achieved by means of a central drive motor 20.
    It is also provided that the two gripping devices 13, 14 are arranged on the gripping device carrier 18 so as to be pivotable about a vertical axis 21.
    11/34
    N2017 / 10500 AT-00
    The gripping device carrier 18 is mounted on a height adjustment device 22, by means of which it can be displaced in its height. As a result, both the work spindles 2, 3 and the various storage levels 10 of the
    Tool magazine 6 can be reached by means of the gripping devices 13, 14.
    The height adjustment device 22 is mounted on a linear guide 23 which extends in the longitudinal direction 24 of the processing system 1. The gripping devices 13, 14 can thus be adjusted in the longitudinal direction 24.
    The height adjustment device 22 comprises guide rails on which the gripping device carrier 18 is slidably mounted. An electric motor, in particular a servo motor, and an adjustment spindle connected to it can serve as the drive for the height adjustment device 22. Of course, other drive units, such as a toothed belt, a rack or the like, can also be used.
    The linear guide 23 also comprises guide rails by means of which the height adjustment device 22 is slidably mounted on the base frame of the processing system 1. For example, an electric motor that interacts with a toothed rack can be used as the drive for the linear guide 23.
    In addition, as can be seen from FIG. 1, it can be provided that a tool insertion station 25 is formed, in which machining tools 4 can be inserted and gripped by the gripping devices 13, 14.
    The tool insertion station 25 can comprise conveying devices, by means of which the machining tools 4 can be conveyed to an additional position at an insertion position, in which the machining tools 4 can be gripped by means of the gripping devices 13, 14. In particular, it is also conceivable that only one tool insertion station 25 is provided, in which tools can be inserted both for the first tool magazine section 7 and for the second tool magazine section 8.
    12/34
    N2017 / 10500 AT-00
    In addition, it can be provided that a measuring device 26 is formed, which is used to measure used processing tools 4. In particular, it can be provided here that the machining tools 4 are moved to the measuring device 26 after removal from the work spindles 2, 3 by means of the gripping devices 13, 14 and are measured there. In particular, it can be provided that the measuring device 26 is formed in the vicinity of the work spindles 2, 3.
    FIG. 2 shows a detailed view of the machining system 1, the same reference numerals or component designations being used for the same parts as in the previous FIG. 1. In order to avoid unnecessary repetition, reference is made to the detailed description in the previous FIG. 1.
    FIG. 2 shows a perspective illustration of an exemplary embodiment of the gripping device carrier 18 together with the first gripping device 13 and the second gripping device 14. As can be seen clearly from FIG. 2, the gripping devices 13, 14 are displaceably mounted on the gripping device carrier 18 by means of a guide rail 27. As a result, the gripping devices 13, 14 can be moved in the transverse direction 19. In particular, it can be provided that the drive motor 20 is coupled to a toothed belt 28 for displacing the gripping devices 13, 14, the toothed belt 28 being connected to a first driver element 29 and a second driver element 30. The first driver element 29 interacts with the first gripping device 13 and the second driver element 30 with the second gripping device 14.
    As can be seen from FIG. 2, the two driver elements 29, 30 are arranged on opposite sides of the toothed belt 28, as a result of which when the toothed belt 28 is moved by means of the drive motor 20, the two gripping devices 13, 14 are displaced in relation to one another.
    As can be clearly seen from FIG. 2, it can be provided in particular that the gripping devices 13, 14 are arranged on a first displacement unit 31 or on a second displacement unit 32, which are relative to the gripping device carrier
    13/34
    N2017 / 10500-AT-00 are movable. The gripping units 15, 16 can be rotatable relative to the displacement units 31, 32 and thus relative to the gripping device carrier 18 with respect to a vertical axis 21. In particular, it can be provided that each gripping device 13, 14 has its own rotary motor 33, by means of which the gripping devices 13, 14 can be rotated relative to the displacement unit 31, 32. The rotary motor 33 can be coupled to the gripping device 13, 14 either directly or by means of a gear or gear. In addition, the rotary motor 33 can be received or arranged on the displacement unit 31, 32.
    3 to 6 show a further and possibly independent embodiment of the machining system 1, again using the same reference numerals or component designations for the same parts as in the previous FIGS. 1 and 2. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding FIGS. 1 and 2.
    3 to 6, the machining system 1 is shown in a greatly simplified representation, with individual method steps being shown when a tool change is carried out.
    As can be seen from FIG. 3, in the first gripping unit 15 of the two gripping devices 13, 14 there is a new machining tool 4 which is to be used in the next machining step and the second gripping units 16 are free. The gripping devices 13, 14 are moved to the work spindles 2, 3 in such a way that the machining tool 4 currently held in the work spindle 2, 3 can be gripped and removed from the work spindle 2, 3 by means of the second gripping unit 16.
    4, the two gripping devices 13, 14 are then moved in the transverse direction 19, so that the new machining tool, which is accommodated in the first gripping units 15, can be inserted into the work spindle 2, 3.
    14/34
    N2017 / 10500 AT-00
    If the machining tool 4 is inserted into the work spindle 2, 3, the machining tool 4 accommodated in the second gripping unit 16 can be brought to the tool magazine 6, as shown in FIG. 5.
    Optionally, the wear of the machining tool 4 can be determined beforehand using the measuring device 26.
    If the gripping devices 13, 14 are now moved to the tool magazine 6, the first gripping unit 15 is free and the processing tool 4 already used is accommodated in the second gripping unit 16. As shown in FIG. 6, the gripping devices 13, 14 are moved to a storage level 10 in such a way that the machining tool 4 already in use can be stored in a free tool holding location 11 and at the same time a new one in a tool holding location 11 which is spaced at the gripping unit distance 17 Machining tool 4 provided for the next machining operation can be accommodated. Here, the second gripping unit 16 is opened in order to be able to put down the processing tool 4 accommodated therein, and the first gripping unit 15 is closed in order to be able to pick up the new processing tool 4. The gripping device 13, 14 can then be moved again to the work spindles 2, 3 in order to be able to use the new machining tool 4.
    The insertion of the new machining tool 4 takes place analogously to the method steps already described, with the second gripping unit 16 not the second gripping unit 15 now being used to hold the machining tool already accommodated in the work spindle 2, 3.
    It is thus provided that the first gripping unit 15 serves to hold the machining tool clamped in the work spindle 2 in every second process pass and the second gripping unit 16 serves to hold the machining tool 4 clamped in the work spindle 2, 3 in every second machining process.
    15/34
    N2017 / 10500 AT-00
    In addition, the gripping devices 13, 14 can be used to re-sort the machining tools in the tool magazine 6 during longer machining operations.
    As can be seen from FIGS. 1 to 6, the tool holding stations 11 can be formed by a storage rail, which can hold the machining tools 4. When using a single storage rail, the processing tool 4 must be mounted in the storage rail in such a way that the processing tool 4 can be held securely in the storage rail by a positive connection. When using two storage rails arranged at a distance from one another, the machining tool 4 can rest on both storage rails.
    The exemplary embodiments show possible design variants, it being noted at this point that the invention is not limited to the specially illustrated design variants of the same, but rather also various combinations of the individual design variants with one another are possible and this variation possibility is based on the teaching of technical action through the present invention Ability of the specialist working in this technical field.
