Description

Technical Field

[0001] This invention relates to an operator's cab for a machine tool and a manufacturing system having at least one machine tool and an operator's cab. According to various aspects, the invention relates to a compactly designed machine tool and its integration into a manufacturing system and a system for machining operations. A compactly designed machine tool is, for example, a machine tool with an operating space of less than 250mm × 250mm × 250mm. Background Technology

[0002] In the exemplary configuration, the machine tool's working space is less than 200mm × 200mm × 200mm. In the exemplary configuration, the machine tool's working space is less than 150mm × 150mm × 150mm. In the exemplary configuration, the machine tool's working space is less than 100mm × 100mm × 100mm. In the exemplary configuration, the machine tool's working space is less than 75mm × 75mm × 75mm. These expressions specifically relate to the feasible feed rates (travel paths) along the X, Y, and Z axes. The working space can be designed as a cube. However, a cuboid structural space is also possible, where the travel paths in the X, Y, and Z axes are not uniform. For example, machine tools designed in this way are suitable for precision machining, such as in the manufacturing of watches and jewelry. Needless to say, other applications are also possible, such as in medical technology, precision technology, and other fields.

[0003] Machine tools and equipment for cutting operations are known. A manufacturing apparatus is known from US2019 / 0084102A1, comprising a plurality of compactly designed machine tools arranged stacked and side-by-side within a common housing, and additionally including a robot for changing tools and / or changing workpieces, the robot being horizontally movable on a vertically movable rod. The apparatus includes an integrated storage device for workpieces that can move with the robot.

[0004] EP2227349B1 discloses a movable robotic unit with a housing, which can be positioned in front of an opening leading to a workspace of a machining machine when necessary, so as to enable the robot to load workpieces. In an operational state, the robotic unit blocks the machine tool's normally worker-accessible entrance.

[0005] A workpiece processing apparatus is known from EP2036664A1, comprising: at least one processing machine; a protective housing with at least one shelf; and a loading device arranged within the protective housing for loading and unloading the processing machine, wherein the loading device includes a slide movable along a guide, the slide having an adjustable cantilever carrying at least one operating unit for a part to be operated, the guide for the slide being disposed in a top region, and the cantilever of the loading device hinged to the underside of the slide having two arms connected to each other and pivotable relative to each other. At least one shelf is part of the protective housing.

[0006] DE3543209A1 discloses a manufacturing system for flexibly manufacturing workpieces, comprising multiple machine tools, a workpiece transfer system connecting the machine tools, and a loading device for each machine tool, arranged between the machine tool and the transfer system and designed for loading and unloading the machine tool. The manufacturing system includes loading and unloading stations spaced apart from each other. Buffer storage is required at each loading and unloading station.

[0007] A structure is known from DE102014114258A1, comprising a single-station cutting machine and a robot unit, wherein the robot unit can be coupled to the cutting machine for loading and unloading, the cutting machine has a machine room, and the robot unit has a robot unit space, which forms a shared processing space when the robot unit is coupled. A buffer storage is arranged within the robot unit. In the operating state, the robot unit blocks the machine tool entrance normally provided to the worker.

[0008] It has been shown that, for example, with compactly designed machine tools, the required components can be manufactured with high precision and efficiency, even if the external dimensions of the machine tool are relatively small.

[0009] However, some studies have shown that in automation, the unique boundary conditions of compactly designed machine tools need to be considered. On the one hand, transfer systems, operating units, and other components cannot be designed to be compact in any arbitrary way. Even if this is technically feasible, in practice, there are usually certain minimum dimensions for transfer systems, operating units, robots, grippers, etc.

[0010] This could make the actual machine tool (or its workspace) very small relative to the automation technology (operation technology, conveying systems, etc.).

[0011] In addition, automation technologies (such as robots with grippers) must interact with the machine tool within its structural space (potentially the workspace) in order to transfer workpieces and, if necessary, cutting tools.

[0012] It has also been shown that even for compact machine tools, direct visual monitoring by the operator is often desirable. Similar to larger machine tools, they typically require an entrance (door) with panes. In automated equipment, this means that the area (the "front" of the machine tool) is precisely where automation technology cannot be used.

[0013] It has also been shown that compact machine tools are typically designed to be smaller than standard automation technologies. This places specific requirements on the automation of compact machine tools. Furthermore, it opens up new possibilities for automation and connectivity that might be impossible with traditional machine tools. Summary of the Invention

[0014] This invention provides an operator's cab for machine tools, particularly suitable for compact machine tools, with the aim of addressing the specific frame conditions inherent in compactly designed machine tools. The operator's cab enables manufacturing systems that achieve partial or even highly automated manufacturing, even with limited structural space. This relates, for example, to workpiece changeover.

[0015] Subsequently, within the scope of the present invention, a manufacturing system having an operating room and at least one machine tool capable of automatic loading and unloading via the operating room for changing workpieces should be provided.

[0016] According to a first aspect, the present invention relates to an operator's chamber for a machine tool, comprising the following components:

[0017] The first loading interface can be connected to the working space of the first machine tool.

[0018] It has an operating unit for operating robots.

[0019] A feed interface for a feed trolley, used to convey workpieces arranged on loading aids, particularly on pallets, and...

[0020] The supply unit moves the loading auxiliary components between the feed trolley and the supply position for delivery between the operating unit and the supply unit.

[0021] In this way, machine tools can be upgraded to enable automated workpiece change. At least in the exemplary configuration, the operator's cab is suitable for a compactly designed machine tool.

[0022] Loading aids are, for example, pallets, shelves, trays, or boxes used to accommodate multiple or even a large number of workpieces. Workpieces may be, for example, precision mechanical parts, watch components, medical technology components, etc. In an exemplary configuration, the loading aid is designed to accommodate both unprocessed workpieces (blanks) and processed workpieces. However, it is also conceivable to use a first type of loading aid for providing unprocessed workpieces and a second type of loading aid for accommodating processed workpieces.

[0023] For example, workpieces with only small dimensions can be processed using machine tools with correspondingly small workspaces. This has a generally positive impact on structural space requirements (floor area). However, if machine tools with only small dimensions and particularly small structural spaces are used, it is advantageous that the operating units with robots interact with the structural space as little as possible.

[0024] This can involve configurations where the operating robot enters the machine tool's structural space solely for the purpose of changing workpieces. Under these configurations, the operating robot completely exits the workspace when no workpiece changing is being performed.

[0025] In the exemplary design, the first loading interface can be closed by a door, so that the workspace is fully separated from the operator's room when no workpiece change is being performed.

[0026] According to an exemplary design, the operating robot is designed to enter the machine tool's workspace through a first loading interface, at least together with a workpiece gripper, so as to deliver workpieces directly to or receive workpieces from the workpiece rack.

[0027] The manipulator robot, along with its workpiece gripper, can drive sufficiently far into the workspace to change workpieces there. This includes, for example, transferring workpieces to be processed to a workpiece rack and receiving processed workpieces from the rack. Since the manipulator robot is not installed within the workspace, the workspace is not occupied by the manipulator robot unless a workpiece change is performed and the manipulator robot, along with its workpiece gripper, has driven out of the workspace.

[0028] According to another example design, the operating robot is a suspended robot, particularly a suspended articulated arm robot. In this way, the operating robot is suspended within the operating chamber, making the area beneath the robot essentially usable as structural space for internal components. This simplifies the process of loading the operating chamber using a feed trolley. The feed trolley is designed, for example, as a ground handling vehicle. Therefore, in the exemplary configuration, the feed trolley can be positioned beneath the operating robot, at least when it is in a drive-in / drive-out state.

[0029] According to another design, the manipulating robot has multiple grippers for the workpiece. These grippers are designed as, for example, dual, triple, or quadruple grippers. Using multiple grippers can accelerate workpiece changeovers. The manipulating robot can pick up a machined workpiece and deliver a workpiece (blank) to be machined within the workspace without having to remove it from the workspace during this process. This also applies to workpiece changeovers at the loading aids location in the supply position.

[0030] According to another design, the operator's cab also has a second loading interface opposite to the first loading interface, which can be connected to the working space of the second machine tool.

[0031] In this way, the control room can be used to supply two machine tools. Even when using a second machine tool, the workspace will not be under excessive pressure even if workpiece changes are not performed.

[0032] According to another design, the operating robot can move along a positioning axis, particularly a horizontally oriented and / or top-cover side positioning axis, between a first loading interface and a second loading interface, wherein the supply position is arranged along the operating robot's travel path, along the positioning axis between the first loading interface and the second loading interface.

[0033] In this way, the robot can operate the first machine tool from the first loading interface and the second machine tool from the second loading interface. The robot's other degrees of freedom allow it, along with the workpiece gripper, to enter the corresponding workspace.

[0034] According to another design, the robot is guided in a following manner above the feed trolley during its displacement movement along the positioning axis between the first and second loading interfaces.

[0035] In this way, the space below (or below or beside) the robot's positioning axis can be used for loading. Thanks to the feed trolley, the operating chamber can have a considerable capacity to receive workpieces. In this manner, both machine tools can be automated and operate autonomously, at least temporarily. This includes, for example, providing unprocessed workpieces (blanks) and receiving processed workpieces from a series of workpieces. The feed trolley can feed multiple blanks into the operating chamber and, after processing, remove them from the operating chamber along with the corresponding number of processed workpieces.

[0036] According to another design, the control room also has a parking position for the feed trolley integrated into the control room housing, wherein loading aids can be transferred between the feed trolley and the supply position when the feed trolley is in the driving state.

[0037] The supply unit can be moved directly to the feed trolley located at the parking position so that the loading auxiliary and the workpiece arranged thereon can move between the feed trolley and the supply position.

[0038] In an exemplary design, the feed trolley can drive completely into the operator's cab. This also includes, for example, partitioning the exterior by a door when the feed trolley has driven in and positioned in its parking position.

[0039] According to another design, the feed trolley has movable fastening elements for securing the loading aids it contains, which are mechanically unlocked when the feed trolley enters the operating chamber.

[0040] The movable fastening element is designed, for example, as a fastening slat. The fastening slat extends to cover multiple or all receiving positions in the feed trolley for loading auxiliary components. In an exemplary design, the fastening slat has rollers that are raised on a ramp as the feed trolley enters the operating chamber. In this way, the fastening slat is also raised. The fastening slat also includes a deflector that at least partially deflects the lifting motion to a horizontal motion during lifting. In this way, the receiving positions can be released when the fastening element retracts laterally.

[0041] According to another design, the supply unit has a vertically oriented lifting axis and a horizontally oriented conveying axis, with a carrier for at least one loading auxiliary component.

[0042] In this way, loading aids can be removed from the feed trolley, and then provided at the supply position using an operating robot for workpiece delivery. For example, the base area in the operator's cab used to transfer the loading aids between the feed trolley and the supply position is only slightly larger than twice the base area of ​​the feed trolley. This also helps to improve the compactness of the operator's cab and the entire manufacturing system.

[0043] In the exemplary design, the conveyor axis is oriented perpendicular to the direction of entry of the feed trolley. This allows the loading aids inside the control room to be removed laterally from the feed trolley. This results in a smaller footprint.

[0044] According to another design, a conveyor axis is arranged on a lifting slide that can move along the lifting axis. The conveyor axis has a linear drive to move into a feed trolley and remove or lower the loading aid into one or more receiving positions of the feed trolley.

[0045] Therefore, only a few driven axes are needed to generate the movement required for changing loading aids. The feed trolley itself does not need to be equipped with active (motor-driven) operating technology.

[0046] In this exemplary design, the transfer axis is parallel to the positioning axis of the operating robot. This allows for efficient use of space within the operator's compartment.

[0047] According to another design, the lifting axis is designed to generate lifting or lowering motions as the carrier moves along the conveying axis into the feed trolley, so as to selectively lift or lower the loading aids from the receiving position.

[0048] In an exemplary design, the operator's cab includes a control unit designed to control the supply unit and, in particular, manipulate the lifting and conveyor axes. The control unit may be part of a higher-level control unit within the manufacturing system.

[0049] According to another design, the supply unit also has a tilting mechanism that tilts the loading aid when necessary to provide a preferred orientation for the workpiece within the loading aid. In this way, the loading aid can be tilted at the supply position. For example, the tilting mechanism is arranged on the carrier along the conveyor axis. Alternatively, this tilting scheme can be omitted from the design.

[0050] By tilting the loading aids, the workpieces slide in a defined direction within their respective receptacles, such as towards a stop. This improves overall accuracy and simplifies workpiece gripping for the operating robot.

[0051] According to another design, the tilting mechanism has: a tilting axis; a retainer spaced apart from the tilting axis and fixed relative to the frame; and a support member capable of engaging with the retainer, wherein, when the support member is engaged, lifting movement along the lifting axis achieves tilting of the loading auxiliary. The retainer can (particularly in the vertical lifting direction) fix the support member in place, such that tilting about the tilting axis is generated during further lifting movement of the lifting slide. In this way, tilting movement can be generated without a separate tilting actuator. For example, a carrier for at least one loading auxiliary can be pivotally supported on the lifting slide, autonomously occupying a non-tilted position under gravity.

[0052] According to another design, the feed trolley can be replaced when the loading auxiliary is available at the supply position for delivering workpieces. This can be achieved, for example, by having the supply unit provide the loading auxiliary at the supply position without interacting with the feed trolley during this period. Then, at least one buffer storage (i.e., a loading auxiliary for accommodating multiple workpieces) is provided at the supply position for multiple workpieces. This ensures a certain time window during which the feed trolley can be replaced. This allows a series of workpieces to be processed with minimal interruption.

[0053] According to another aspect, the present invention relates to a manufacturing system for cutting manufacturing, particularly for manufacturing precision mechanical parts, the manufacturing system having the following components:

[0054] At least one machine tool with a particularly compact design, designed for multi-axis machining and having a tool holder and a workpiece holder that can move relative to each other along at least three axes.

[0055] The tool holder and workpiece holder are supported on the rear side of the machine tool's working space, and

[0056] The operator's cab of at least one of the configurations described herein is wherein the first loading interface is laterally connected to the working space of the machine tool.

[0057] In this way, machine tools can operate at least partially automatically. This includes, for example, batch manufacturing, where workpiece changes can be partially or fully automated.

[0058] Therefore, at least in the exemplary configuration, the front of the workspace is open and can be observed and entered by the operator. The front can also be referred to as the operator's side. The front is arranged opposite to the rear. The lateral surfaces of the workspace can be used for operations (workpiece change, tool change). In this way, a compact design is achieved.

[0059] The operator's cab is located adjacent to the machine tool's workspace, for example, at a short distance to it along the side. The operating unit corresponds to the operator's cab, not the machine tool. This means that for machine tools with only a relatively small workspace, complex interventions and adjustments are not required.

[0060] The operating unit can reach the workpiece rack and any holding devices already positioned there to perform workpiece changes (loading and unloading) within the workspace. This also affects the removal of residues (waste).

[0061] In the exemplary design, the tool holder is designed as a tool spindle and has a vertically oriented axis. The workpiece holder corresponds, for example, to the pivot axis or rotary table of a machine tool.

[0062] According to an example embodiment, the manufacturing system further includes:

[0063] At least one additional, particularly compact, machine tool designed for multi-axis machining and having a tool post and a workpiece holder capable of moving relative to each other along at least three axes, wherein the tool post and workpiece holder are supported on the rear side of the machine tool's workspace, wherein,

[0064] The control room has a second loading port that is opposite to the first loading port.

[0065] The first loading interface is connected laterally to the working space of the first machine tool, and

[0066] The second loading interface is connected laterally to the working space of the second machine tool.

[0067] In this way, two machine tools can be operated in an automated or at least partially automated manner using only one control room. This is especially relevant to the workpiece changeover process.

[0068] According to another example design, the first machine tool and the second machine tool each have a loading side defined relative to the workspace, the loading side being arranged identically for the first machine tool and the second machine tool relative to their respective workspaces, the first machine tool and the second machine tool being arranged opposite to each other and staggered from each other by 180° around an imaginary vertical central axis and connected to the operator's cab.

[0069] The advantage of this arrangement is that the operator's cab can be positioned between two essentially similar or even identical machine tools, where the corresponding side of the workspace (relative to the machine tool's workspace and tool spindle) serves as the loading side (workpiece changing side). In other words, from the operator's perspective, the operator's side of the first machine tool and the operator's side of the second machine tool face opposite directions. For example, the side of the machine tool facing away from the operator's cab is the equipment side (tool changing side).

[0070] It goes without saying that the features mentioned above and those to be explained below can be used not only in the combinations given separately, but also in other combinations or individually, without departing from the scope of the invention. Attached Figure Description

[0082] Figure 1 An exemplary configuration of a machine tool 10, suitable for producing precision mechanical parts, is illustrated using a perspective view. The machine tool 10 includes a frame 12, which, in the exemplary design, includes a sub-frame 14 on which a frame assembly 16 is supported. Significant forces generated during machining are absorbed by the frame assembly 16. The sub-frame 14 serves as a support for the frame assembly 16. Figure 1 The control device of the machine tool 10 is also indicated by 18. The control device 18 controls the components and functions of the machine tool 10 to process the workpiece in a desired manner. Control via external equipment is also possible.

[0083] Machine tool 10 also includes a motion mechanism 20, which is designed as a multi-axis motion mechanism. In at least some of the figures, for illustrative purposes, an XYZ Cartesian coordinate system is shown. The XYZ coordinate system includes an X-axis (lateral), a Y-axis (depth direction), and a Z-axis (height direction). In an embodiment, the X and Y axes are horizontal axes. In an embodiment, the Z-axis is a vertical axis. The XYZ axes are orthogonal to each other. The XYZ coordinate system is primarily used to illustrate and explain the components and functions of machine tool 10. It goes without saying that other coordinate systems can also be used for these purposes. Therefore, the XYZ coordinate system should not be construed as limiting. Those skilled in the art can readily implement the conceptual steps required to convert to other coordinate systems.

[0084] In this embodiment, the motion mechanism 20 includes various components that are directly or indirectly supported on the frame block 16. This ensures a shorter force transmission path and high rigidity. Figure 1 The diagram also shows a workspace, indicated by 24, in which machining is performed using machine tool 10.

[0085] The machine tool 10 also includes a workpiece holder (also referred to as a workpiece receiver) 30 for accommodating at least one workpiece to be processed. A tool spindle 32 is also provided. The tool spindle 32 includes a tool holder 34 designed to accommodate a tool 36. The tool 36 can be driven in a rotary manner to process the workpiece held by the workpiece holder 30.

[0086] In one embodiment, the workpiece holder 30 is mounted on a single-sided guided cantilever 40, which houses a pivot drive or rotation drive 42 for the workpiece holder 30. The axis of rotation provided in this manner can also be referred to as the C-axis. The cantilever 40 is connected to a Y-axis linear drive 46 via another pivot drive 44, which is in turn supported on the frame assembly 16. The pivot drive 44 provides a axis of rotation that can be referred to as the B-axis. The Y-axis linear drive 46 provides a axis of translation that can be referred to as the Y-axis.

[0087] The tool spindle 32 is connected to the frame assembly 16 via a Z-axis linear driver 50 and an X-axis linear driver 52. The Z-axis linear driver 50 provides a translation axis, also referred to as the Z-axis. The X-axis linear driver 52 provides a translation axis, also referred to as the X-axis. The Z-axis linear driver 50 and the X-axis linear driver 52 form a cross slide driver. In an embodiment, the two translation axes (X, Z) correspond to the tool spindle 32 or the tool 36. The translation axis (Y) corresponds to the workpiece holder 30 or the workpiece. Furthermore, in an embodiment, the two rotational axes / pivot axes (B, C) correspond to the workpiece holder 30 or the workpiece. Other types of correspondences are also possible and are related to the concept of machine kinematics.

[0088] In summary, machine tool 10 provides a compact workspace 24. This results in a small overall size, light weight, and low energy demand for machine tool 10. However, due to the structural rigidity, a high level of accuracy and high cutting power can be guaranteed. Since the workpiece holder 30 and tool holder 34 are arranged directly or indirectly on the frame assembly 16 and the sub-frame 14 of the frame 12 and supported on the rear side of the workspace 24, the workspace 24 is easily accessible. Therefore, in principle, three sides (front and two lateral sides) are available for horizontal access to the workspace 24.

[0089] Figure 2 The design of manufacturing system 60 is shown in perspective. Manufacturing system 60 includes machine tool 10, which is based on... Figure 1 The structural design is shown in the figure. Furthermore, an operator's compartment 70 is provided, which is laterally connected to the machine tool 10 or its workspace 24. In this embodiment, "laterally" means that the connection is neither made at the rear nor at the front.

[0090] According to Figure 2In one embodiment, the manufacturing system 60 further includes an equipment unit 66, which is also laterally connected to the workspace 24 of the machine tool 10. For example, the machine tool 10 is arranged between the equipment unit 66 and the operator's cab 70. The machine tool 10 stands on a base frame 72, which, in this embodiment, is supported on its underside. The workspace 24 and other components of the machine tool 10 may be enclosed by a machine tool housing 76. In this embodiment, the machine tool housing 76 also houses the equipment unit 66. This should not be construed as limiting.

[0091] The workpiece holder 30 and the tool holder 34 are arranged in the workspace 24 and supported on the rear side 94 of the workspace 24. In this way, easy access is possible from the front side opposite the rear side 94, referred to as the operator side 88. The workspace 24 is accessible via inlet 82. The workspace 24 is clearly visible from the operator side 88. In an embodiment, a workspace door 84 is provided, which closes the inlet 82 as needed. For example, the workspace door 84 is designed as a revolving door. It is also conceivable to construct the workspace door 84 as a sliding door, particularly as a vertically movable sliding door that moves upward to open the inlet 82.

[0092] Figure 2 A control panel 86 is also shown facing the operator standing on the operator's side 88. The control panel 86 interacts with the control unit 18 (see [reference]). Figure 1 The control panel 86 is used to control and monitor the machine tool 10. In an exemplary configuration, the control panel 86 is also used to control and monitor the operator's cab 70 and / or equipment unit 66.

[0093] The operator compartment 70 is designed in a cabinet shape. The operator compartment 70 enables automated workpiece changing. In an exemplary configuration, the operator compartment 70 also serves for at least temporary storage of workpieces (blanks and / or machined workpieces). The operator compartment 70 is placed on a frame 74 and includes an operator compartment housing 78. In an embodiment, an operator compartment door 98 is provided, through which access to the interior space of the operator compartment 70 is made.

[0094] exist Figure 2 The diagram also shows an operating unit 100 in an operating room 70, which includes an operating robot 102. In an embodiment, the operating robot 102 is a suspended robot and is supported, for example, on the top side (above), see [reference]. Figure 2 The top cover side marked 104.

[0095] based on Figure 2 , Figure 3 A schematic top view of manufacturing system 60 is shown. According to... Figure 3 Implementation examples and according to Figure 2 The difference in the illustrations is that, in Figure 3An operator's cab 70 is provided, positioned between the first and second machine tools. In this embodiment, the machine tools 10 are designed of the same type. Each of the two machine tools 10 includes a workspace 24 with a workpiece holder 30 and a tool spindle 32. The orientation of the machine tools 10 is shown in the (machine) coordinate system XY. The Z-axis is perpendicular to the observation plane.

[0096] The control room 70 is equipped with Figure 3 The operating unit 100 is shown only in block form. The operating chamber 70 has a first loading interface 110 facing the first machine tool and a second loading interface 112 facing the second machine tool. Arrow 114 shows the loading process through the first loading interface 110. Arrow 116 shows the loading process through the second loading interface 112. The operating chamber 70 is designed such that it can only be accessed in the workspace 24 of the machine tool 10 during actual workpiece changes. If no workpiece change is being performed, for example, during machining of a workpiece held on the workpiece holder 30, the operating chamber 70 will not intervene in the corresponding workspace.

[0097] The machine tool 10 includes a rear side 94, on which the workpiece holder 30 and the tool spindle 32 are directly or indirectly supported. The operator side 88 is arranged opposite to the rear side 94, through which the operator can see and / or reach the workspace 24.

[0098] The first lateral surface of the working space 24 of the machine tool 10 serves as the loading side 106. On the loading side, a first loading interface 110 and a second loading interface 112 are connected to the working space 24. The side opposite to the loading side 106 serves as the equipment side 124. On the equipment side, equipment units 66 are connected via equipment interfaces 122. Equipment interfaces 122 can also be referred to as tool change interfaces. According to... Figure 3 In the embodiments shown, of the two machine tools 10, the loading side 106 is positioned on the same side of the workspace 24 when viewed through the front / operator side 88. Figure 3 In the middle, the two machine tools 10 are spaced apart from each other and offset from each other by 180° with respect to each other about the (imaginary) vertical central axis 132.

[0099] In this way, two machine tools 10 of the same type can be housed in the same operator's compartment 70. On the one hand, this results in a compact design of the manufacturing system 60, and on the other hand, it allows for easy access via the respective operator's side 88 of the machine tool 10. In this regard, also see the exemplary arrangement of the respective operators, according to... Figure 3 In the top view, the control panel 86 is located near the operator side 88 of the machine tool 10.

[0100] According to Figure 3In an exemplary embodiment, the control chamber door 98 of the control chamber housing 78 of the control chamber 70 is open. The control chamber 70 has a feed inlet 136 through which a feed trolley 140 can enter the interior space of the control chamber housing 78 in the entry direction 138. Once the feed trolley 140 has entered the control chamber housing 78, the control chamber door 98 can be closed. Therefore, typically no individual workpiece or individual loading aid is individually conveyed via the feed inlet 136.

[0101] Conversely, feed port 136 is used for loading and unloading feed trolley 140, which may include multiple loading aids and optionally contain a large number of workpieces. In this way, operating chamber 70 can also be used as a storage or temporary storage. This enables manufacturing system 60 to operate with a high degree of automation and at least temporarily autonomy. In this embodiment, feed trolley 140 is used to accommodate unprocessed workpieces (blanks) and processed workpieces (finished parts). This should not be construed as limiting.

[0102] Figure 4 A perspective view is used to show the state of the operating chamber 70, where the feed trolley 140 has entered its parking position 142 within the operating chamber housing 78. In this state, the operating chamber door 98 can be closed, allowing the feed trolley 140 to be fully contained within the operating chamber housing 78. This allows for safe and error-free operation of the operating chamber 70. Any processing is protected by the operating chamber housing 78. Furthermore, Figure 4 (Partially) shown is the operating robot 102, which can be guided toward the workspace 24 of the machine tool 10 via the first loading interface 110 and / or the second loading interface 112 when necessary to change workpieces.

[0103] The feed trolley 140 has multiple receiving positions 144, which are designed as slide-in units in this embodiment. For example, five or more receiving positions 144 are provided, arranged overlapping each other. The receiving positions 144 are used to receive loading aids 150. For example, pallets or trays can be used as loading aids 150. The use of so-called Euroboxes or similar loading aids is also conceivable. It is important that the loading aids 150 can be inserted into the receiving positions 144. In this embodiment, the conveying direction of the loading aids 150 is generally perpendicular to the driving direction 138 of the feed trolley 140.

[0104] According to Figure 4 In this embodiment, a cover 146 is also provided, which covers the movement space used by the operating robot 102 arranged on the top cover side from below. The feeding trolley 140 is positioned in the parking position 142, below the cover 146 (see also...). Figure 8 It is protected by cover 146.

[0105] In this embodiment, the fastening element 148, designed as a fastening strip, is used to secure the loading auxiliary 150 in the receiving position 144 of the feed trolley 140. Figure 5 The diagram illustrates the mechanical deactivation (and activation) of the fastening element 148 as the feed trolley 140 enters (and extends). The feed trolley 140 has a traveling mechanism 152. The feed trolley 140 is rollable and can travel in the entering direction 138 into the parking position 142. At least one roller 154 is arranged on the fastening element 148, and as the feed trolley 140 enters, at least one roller 154 contacts a ramp 156 connected to the frame 74 of the operating room 70. As the feed trolley 140 enters, the roller 154 is lifted by the (fixed) ramp 156, thereby raising the fastening element 148 as well.

[0106] The fastening element 148 is movably arranged on the feed trolley 140 via an inclined deflector 158. In this way, the lifting motion when the roller 154 is raised is at least partially deflected to horizontal motion (parallel to the driving direction 138 in this embodiment). This allows the fastening element 148 to disengage laterally, enabling the loading aid 150 to be removed from its receiving position 144. Once the feed trolley 140 has moved out of its parking position 142, the fastening element 148 is reactivated. Outside its parking position 142 in the operating chamber 70, the loading aid 150 is fully secured in its position within the receiving position 144 of the feed trolley 140.

[0107] Figure 6 The supply unit 160 is shown in a side view (view orientation corresponding to the driving direction 138), which is used to transfer a loading aid 150 carrying a workpiece between the feed trolley 140 and the operating unit 100. The supply unit 160 can position the loading aid 150 in a supply position in which the operating unit 100 can reach the loading aid. Figure 7 The diagram also uses a partial perspective view to show the supply unit 160 and its interaction with the feed trolley 140. See also... Figure 8 and Figure 9 The illustration is shown in the image.

[0108] In this embodiment, the supply unit 160 has a lifting axis 162 and a conveying axis 168. The lifting axis 162 is vertically oriented. The conveying axis 168 is horizontally oriented. The conveying axis 168 is oriented substantially perpendicular to the infeed trolley 140's driving direction 138.

[0109] The lifting axis 162 includes a vertically movable lifting slide 164 coupled to a lifting drive and carrying a component of the conveyor axis 168. The conveyor axis 168 includes a horizontally movable carrier 170 for accommodating the loading aid 150. By moving along the lifting axis 162, the carrier 170 can manipulate a selected receiving position 144 in the feed trolley 140. The carrier 170 can be moved into or out of the feed trolley 140 via the conveyor axis 168 to convey the loading aid 150.

[0110] According to Figure 7 In this embodiment, tray 174 serves as loading aid 150. Other types of loading aids are also conceivable. Loading aid 150 is used to receive workpiece 176, which is positioned in a suitable receiving portion. Picking up loading aid 150 from receiving position 144 or placing loading aid 150 in / on receiving position 144 of feed trolley 140 typically involves positioning carrier 170 along conveying axis 168 and performing a (small) lifting movement along lifting axis 162 to raise or lower within feed trolley 140. If carrier 170 is removed from feed trolley 140 using loading aid 150, a lifting movement (typically larger in amount) occurs along lifting axis 162 to position loading aid 150 in a supply position. The necessary manipulation of lifting axis 162 and conveying axis 168 is via control device 18 of operator room 70 or manufacturing system 60 (see...). Figure 1 (or other control devices)

[0111] The transmission axis 168 includes a linear drive 180, which may include, for example, a cylinder. According to... Figure 7 In one embodiment, a mechanism for engaging the profile of the loading aid 150 is also shown. For this purpose, a drive pin 182 is provided, which engages in a drive recess 184. See also... Figure 9 The diagram shows the drive pin 182 and the linear actuator 180. In the exemplary configuration, the drive notch 184 tapers towards the lifting slide 164, for example, in a V-shape, so that centering can be achieved when the drive pin 182 pulls the loading aid 150 out of the feed trolley 140 via the drive notch 184.

[0112] In one embodiment, the drive notch 184 is arranged in a protruding tab within the loading aid 150. In another embodiment, the drive pin 182 is arranged on a carrier 170 movable along the conveyor axis 168 via a linear actuator 180. When the loading aid 150 is placed in the receiving position 144 of the feed trolley 140, engaging or disengaging the drive pin 182 relative to the drive notch typically requires a (smaller) lifting movement along the lifting axis 162.

[0113] In the exemplary configuration, the carrier 170 of the transfer axis 168 also includes an inclined axis 188. If necessary, the carrier 170 and the loading aid 150 disposed thereon can be slightly tilted about the inclined axis 188. This allows the loading aid 150 and / or the workpiece 176 to be provided in a preferred orientation. This simplifies the process of delivering the workpiece 176 in the supply position to the operating unit 100.

[0114] Figure 8 Use the side view (and) Figure 6 The view orientation is similar to that shown to illustrate the interaction between the operating unit 100 and the supply unit 160. The operating unit 100 has an operating robot 102 guided on the top cover side 104 of the operating chamber 70 (see also...). Figure 2 In an exemplary configuration, the operating robot 102 is positioned at least in an in-drive state above the feed trolley 140 and the supply unit 160.

[0115] In an exemplary configuration, the manipulating robot 102 is designed to provide workpiece 176 as needed via a first loading interface 110 of a first machine tool and / or via a second loading interface 112 of a second machine tool. This includes at least partially moving the manipulating robot 102 into the corresponding workspace 24 of the machine tool 10. The first loading interface 110 and the second loading interface 112 are spaced apart from each other, see also [reference needed]. Figure 3 The diagram is shown in the image.

[0116] To bridge the distance between the first loading port 110 and the second loading port 112, a positioning axis 192 is used, along which the manipulator 102 is horizontally movably guided via a slide 194. According to... Figure 8 In this embodiment, the positioning axis 192 is parallel to the transfer axis 168. This should not be construed as limiting. The operating robot 102 can move along the positioning axis 192 to obtain a favorable position relative to the first loading interface 110 and the second loading interface 112. If only a single first loading interface 110 is provided, the positioning axis 192 can be omitted if necessary.

[0117] The operating unit 100 is used to transfer workpieces 176 between the supply position and corresponding workpiece holders 30 in the workspace 24 of the machine tool 10. This is done via a first loading interface 110 and a second loading interface 112 into the corresponding workspace 24. (See reference) Figure 8 and Figure 9 The diagram shows a tilting mechanism 200 that allows a carrier 170 with a loading aid 150 housed thereon to tilt about a tilting axis 188. Figure 8The tilt position of carrier 170 is indicated by a dashed line. Targeted tilting of carrier 170 allows for the preferential orientation of workpiece 176. This increases accuracy and simplifies the gripping (or placement) of workpiece 176 by the workpiece gripper of robot 102.

[0118] The carrier 170 is pivotally supported on a lifting slide 164 about an inclined axis 188. Inclination can be specifically achieved in the supply position by means of the tilting mechanism 200. For this purpose, a retainer 204 is provided, which is supported on the frame side of the operating chamber 70. The carrier 170 has a support 206 that can be engaged into the retainer 204 as needed. Figure 9 In the illustration, the retainer 204 and the support 206 are shown spaced apart from each other. For example, the retainer 204 has a groove 208 into which the roller 210 of the support 206 can engage. When the support 206 engages in the retainer 204, the retainer 204 holds the support 206, and further holds the carrier 170 as the lifting slide 164 moves further along the lifting axis 162. This can be achieved when the lifting slide 164 is slightly lowered along the lifting axis 162. Figure 8 The tilt position of carrier 170 is shown by the dashed line.

[0119] This allows the carrier 170 to tilt around the tilt axis 188, similar to... Figure 8 and Figure 9 The curved double arrow 202 also illustrates a configuration in which an actuator 216 is supported on a carrier 170. The actuator 216 is designed to engage or disengage the support 206 as needed, see the double arrow 218 showing the direction of movement. In this way, the roller 210 can enter the groove 208. In principle, it is also conceivable not to use the actuator 216. Then, for example, by moving the carrier 170 along the defined direction of the transmission axis 168, the support 206 can be moved into the retainer 204.

[0120] Figure 10 An exemplary configuration of the manipulator 102 of the manipulator unit 100 is shown using a partial perspective view. In this embodiment, the manipulator 102 is designed as an articulated arm robot. However, other configurations of the manipulator 100 are also conceivable. The manipulator 102 is a suspended robot. If necessary, a positioning axis 192 is provided on the top cover side (or wall side) (see...). Figure 8 ).

[0121] To grip or place workpieces, the manipulator 102 has an end effector in the form of a workpiece gripper 230. In this embodiment, the workpiece gripper 230 is designed as a multi-gripper 232. In this way, the workpiece gripper 230 can pick up a blank 240 from the loading aid 150 and deliver the processed workpiece 242 to the loading aid 150 without having to move to the workpiece rack 30 of the machine tool 10 during this process. This also applies to workpiece changes in the workpiece rack 30 within the workspace 24 of the machine tool 10. This reduces workpiece changeover time.
