Description

Technical Field

[0001] This invention relates to a device for discharging chips from a machine tool and a manufacturing system having at least one machine tool and a chip discharging device. In various aspects, the invention relates to a compactly designed machine tool and its integration into a manufacturing system, and to a system for machining operations. A compactly designed machine tool is, for example, a machine tool with a working 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 on 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 robots for changing tools and / or changing workpieces. A system for collecting chips is also provided within the housing.

[0004] A vertical machining center is known from EP2394778A1, which has a working area in which a vertically oriented tool spindle is arranged. The working area is funnel-shaped and tapers downwards, with an opening at the bottom through which chips and the like fall out of the working area. A (driven) chip conveyor is arranged below the bottom opening, which transports the chips falling from the working area horizontally and vertically to an area behind the machining center, where the chips are transferred from above to a movable chip trolley.

[0005] 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.

[0006] However, some studies have shown that special boundary conditions in compactly designed machine tools need to be considered in terms of automation. On one hand, transfer systems, operating units, etc., cannot be designed to be compact in any arbitrary way. Even if this is technically feasible, in practice, there are usually minimum dimensions for transfer systems, operating units, robots, grippers, etc. The same applies to handling chips, coolant lubricants (KSS), etc.

[0007] This may make the actual machine tool (or its workspace) very small relative to the automation technology (operation technology, conveyor systems, chip management, KSS management, etc.).

[0008] 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 systems, this means that this area (the "front" of the machine tool) is precisely where automation technology and other components cannot be used.

[0009] It has also been shown that compact machine tools are typically designed to be smaller than standard automation technologies. This creates specific requirements for the automation of compact machine tools. Furthermore, it opens up new possibilities for automation and connectivity that were impossible with traditional machine tools. Summary of the Invention

[0010] The object of this invention is to provide a device for discharging chips from machine tools, particularly suitable for compact machine tools. This device should, as far as possible, take into account the specific frame requirements of machine tools with compact designs. With this device, even with limited structural space, a manufacturing system achieving partial or even highly automated manufacturing should be possible. This relates, for example, to the collection and handling of chips. The device should provide sufficient capacity to accommodate the chips, enabling the machine tool to operate at least temporarily and autonomously.

[0011] The device should provide a container for holding the chips, which should be easily replaceable when full. Finally, within the scope of this invention, a manufacturing system comprising a machine tool and a means for discharging the chips will be provided. Overall, the manufacturing system should be compact and user-friendly in design.

[0012] According to a first aspect, the present invention relates to a device for a machine tool for discharging chips, the device comprising:

[0013] A movable chip trolley having a receiving portion for a chip basket that can be removed from the chip trolley.

[0014] The chip carriage parking position for chip carriages integrated into the machine tool housing, particularly located below the machine tool's working space, and

[0015] A connector located between the opening of the chip basket and the chip discharge opening of the working space to discharge chips from the working space.

[0016] The connector can be moved between a release position and a running position. In the release position, the chip trolley can be moved out of the chip trolley parking position. In the running position, the connector is connected to the chip trolley to transfer chips from the workspace into the chip trolley.

[0017] In this way, chip transfer can be carried out in the most direct manner, ideally without the need for an additional (driven) chip conveyor between the workspace and the chip trolley. Overall, this achieves a compact structure while also taking into account the automation technology and auxiliary functions of the machine tool.

[0018] The connection between the machine tool's working space and the chip trolley is sufficiently sealed, minimizing the likelihood of contamination in the running position of the connector during machine operation. In the released position, the chip trolley can be easily moved from its parking position. For example, a chip trolley with a full chip basket can be replaced with a new chip trolley with an empty chip basket. However, it is also conceivable to empty the chip basket of the chip trolley and / or replace it with an empty chip basket.

[0019] In the exemplary design, the connector remains in the parking position when the chip trolley is driven out of the parking position. According to this design, the connector remains continuously connected to the machine tool.

[0020] In the operating position, the connector is fully and securely connected to the chip trolley. This includes, for example, the connection between the connector and the chip trolley for the chip seal and, in particular, the connection for the KSS- seal. In this way, contamination of the machine tool and its surrounding environment by chips and / or KSS- (cooling lubricant) can be effectively reduced or avoided.

[0021] When the machine tool is running to process a workpiece, the chip trolley is enclosed by the housing. This achieves a unified design. For example, the housing has a door through which the chip trolley can enter the parking position when the connector is in the released position. Therefore, the chip trolley has a traveling mechanism. The chip trolley can slide / move.

[0022] In this exemplary design, the chip trolley is changed from the front, or front side. The chip trolley can be moved into or out of its parking position from the front of the machine tool. This is the opposite of the machine principle of chip conveyors and chip trolleys, in which chips are conveyed rearward or sideways. This simplifies machine tool operation because the main components can be operated from one side and the same side (front, operator side).

[0023] The device is used to handle chips (also known as chip management). This process includes collecting the chips and, at least in part, collecting the coolant adhering to the chips. The chips and KSS fluid can be at least partially reused or recycled.

[0024] The process of transferring chips from the workspace to the chip trolley can be carried out without an additional chip conveyor. For example, chips can fall from the workspace into the chip basket of the chip trolley with gravity assistance.

[0025] According to the exemplary design, the chip trolley has a cylindrical structure in which the connecting member is located above the chip trolley and below the working space. This is applicable at least to cases where the chip trolley is in the parking position. In other words, according to this configuration, the chip trolley can be placed below the machine tool working space. This facilitates chip transport, allowing chips to fall from the working space and reach the chip trolley without the need for an additional drive. In the exemplary design, the height (in the Z direction) of the cylindrical structure is at least twice the width (in the X direction) and / or twice the depth (in the Y direction) of the structure.

[0026] The machine tool's compact design allows for a workspace positioned at a certain height above the ground, such as at table or column height from the operator's perspective. In this way, the space below the workspace can be used for other functions, such as chip management.

[0027] For example, the machine tool's working space is located in the upper structure of a manufacturing system with a cabinet-like design. Similarly, the chip trolley's parking position is located in the lower structure of the same manufacturing system.

[0028] In the exemplary design, viewed from above, the parking position for the chip trolley is located within the cross-section occupied by the workspace.

[0029] According to another exemplary design, from the perspective of the chip discharge opening in the workspace, free, gravity-assisted chip transfer along the chip discharge path toward the chip basket is feasible. In the exemplary configuration, this includes a direct, free connection (without deflection) between the workspace and the chip basket of the chip trolley.

[0030] According to another exemplary design, chip transfer between the chip discharge opening and the chip basket occurs without a drive, wherein the chip discharge path extends substantially vertically between the workspace and the chip basket. Chips can fall freely into the chip basket. A driven chip conveyor is not required.

[0031] According to another exemplary design, the connector can move vertically, wherein a locking element is provided that, when needed, secures the connector in a released position. In this way, the connector can be selectively moved to the released position when the chip trolley or chip basket needs to be replaced and / or emptied.

[0032] According to another exemplary design, in the operating position, the connector is placed on the edge of the chip trolley, particularly the edge of the circumferential or annular seal, using a seal, especially a circumferential or annular seal, wherein the connector has a through-hole facing the chip basket, which in the operating position opens from above into the opening of the chip basket.

[0033] In this way, the possibility of contamination is further reduced. The connector, by its own weight, can be placed securely on the edge of the chip trolley with a sufficiently tight seal. The connector can be easily disconnected from the chip trolley.

[0034] According to another exemplary design, the chip trolley, extending vertically, has: a traveling mechanism, a KSS-operating section, and a receiving portion for the chip basket, wherein the KSS-operating section is arranged between the traveling mechanism and the receiving portion, and the receiving portion surrounds the chip basket in a multi-sided sealed manner, and the KSS-operating section has an operating opening that can be reached by the operator even when the chip trolley is positioned in the chip trolley parking position. This includes, if necessary, a door for opening the casing.

[0035] In this way, the chip trolley can be easily separated from the KSS container, thus allowing for effortless emptying or replacement. The process of moving the chip trolley from its parking position includes, for example, opening the casing door, moving the connector to the release position, and disconnecting the KSS discharge line from the KSS operating section.

[0036] According to another exemplary design, a KSS discharge line with quick-connect fittings is arranged in the KSS operating section, and the KSS discharge line can be operated through the operating opening. In this way, KSS fluid that has previously been mixed with chips can be collected.

[0037] According to another exemplary design, at least the receiving portion of the chip trolley is arranged above the movable KSS-trough, wherein the KSS-trough has at least one recess for the chip trolley, particularly for the traveling mechanism of the chip trolley. In other words, in an operational state, the chip basket of the chip trolley is arranged between the workspace (or connector) and the KSS-trough. The KSS-trough is arranged below the chip basket. The chip basket is located below the workspace. At least one recess in the KSS-trough for the chip trolley allows the chip trolley to be moved in and out. Both the KSS-trough and the chip trolley can be accommodated on the underside, for example, by a corresponding traveling mechanism or frame.

[0038] According to another exemplary design, the device also has a lower ground resting position for the movable KSS-trough, which can be moved out of the lower ground resting position when the chip trolley is moved out of the chip trolley resting position. In this way, the KSS-trough can also be easily replaced and / or emptied. The structural space located below the machine tool's working space is well utilized. The compact structure of the machine tool is preserved.

[0039] According to another exemplary design, the travel mechanisms of the KSS-trough and the chip trolley are arranged in a manner that overlaps with each other at least in segments. This specifically relates to the utilization of the space beneath the machine tool's working space in the ground area. The term "overlap" refers to geometric overlap (see overlapping fingers). The overlap enables the guidance and movement of the chip trolley and the KSS-trough on the underside.

[0040] In an exemplary design, the KSS-trough provides at least one guide for the chip trolley, which the chip trolley can drive into the guide by its travel mechanism when it enters the parking position.

[0041] According to another exemplary design, the traveling mechanism of the chip trolley includes at least three rollers. The connection points between the rollers and the traveling mechanism open a first surface. The KSS-trough has a traveling mechanism with at least three rollers. The connection points between the rollers and the traveling mechanism of the KSS-trough open a second surface, and the first and second surfaces at least partially overlap in the top view. Typically, the surface opened by the at least three rollers is a horizontal plane. The at least partial overlap of these surfaces also indicates that the structural space below the machine tool's working space is well utilized. The top view includes a vertical view (from above or below along the Z-axis).

[0042] According to another exemplary design, the KSS-tank has a KSS-container that is at least segmented in a U-shape and interrupted by a notch in the top view, at least one segment of the traveling mechanism of the chip trolley can reach the notch. The top view is taken along the vertical axis and correspondingly shows the horizontal plane of the device.

[0043] For example, a notch is used to accommodate the two right-side or two left-side rollers of the chip carriage's travel mechanism, where the two rollers form a track.

[0044] According to another exemplary design, the base surface of the KSS-trough in the top view is at least 50% larger than the base surface of the chip trolley (or chip basket). In another exemplary design, the base surface of the KSS-trough in the top view is at least 100% larger than the base surface of the chip trolley (or chip basket).

[0045] According to another exemplary design, the vertical extension occupied by the chip basket is at least 50% greater than the vertical extension of the KSS-tank (or KSS-container). According to another exemplary design, the vertical extension occupied by the chip basket is at least 100% or even 200% greater than the vertical extension of the KSS-tank (or KSS-container).

[0046] In this way, the KSS-tank can be designed flat, yet still has a high capacity. KSS fluid can flow into the KSS-tank and diffuse there. Conversely, the chip basket of the chip trolley has a greater vertical extension, thus achieving a large capacity there as well. Chips can accumulate and be stored stacked on top of each other in the chip basket.

[0047] According to another aspect, the present invention relates to a combination of a device for removing chips according to the invention and a machine tool according to the invention.

[0048] Furthermore, the present invention relates to a manufacturing system for cutting processes, particularly for manufacturing precision mechanical parts, comprising the following components:

[0049] At least one particularly compact machine tool 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 within the machine tool's workspace, and

[0050] According to at least one device for discharging chips, as shown herein, the device for discharging chips is arranged at least substantially below the work space.

[0051] Specifically, in this way, chips generated in the workspace can be directly guided to the chip basket of the chip trolley without a chip conveyor. Chips generated during machine operation can be collected in the chip trolley. The chip trolley itself or the chip basket contained within it can be quickly and easily replaced or emptied.

[0052] The chip trolley primarily occupies the space below the machine tool's workspace, where the KSS-slot can also be arranged. Therefore, at least in the exemplary configuration, the front of the workspace is open and accessible to the operator. The front can also be referred to as the operator's side. The front is arranged in opposition to the rear. The lateral surfaces of the workspace are available for operations (workpiece change, tool change). This arrangement achieves a compact design.

[0053] For example, the manufacturing system includes multiple chip trolleys, one of which has been moved to a parking position under the machine tool. The chip trolley can then be quickly replaced by replacing the full one with an empty one. Alternatively, simply replacing the chip basket can also be considered. In this way, the machine tool's operational capability can be quickly restored when the chip basket is full.

[0054] According to another exemplary design, the chip trolley has a cross-section in a top view that lies within the projection of the machine tool's working space. In this way, the chip trolley does not increase or only slightly increases the footprint of the manufacturing system.

[0055] According to another exemplary design, the manufacturing system has a cabinet-like enclosure surrounding an upper part and a lower part, with the machine tool and its working space arranged in the upper part, and the chip trolley in the lower part, arranged below the machine tool's working space. In the exemplary design, the manufacturing system includes a shared housing (also called enclosure) for the machine tool and a parking position for the chip trolley.

[0056] It goes without saying that the features mentioned above and those to be explained below can be used not only in the given combinations, but also in other combinations or individually, without departing from the scope of the invention. Attached Figure Description

[0067] 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 lower frame 14 on which a frame assembly 16 is supported. Significant forces generated during machining are absorbed by the frame assembly 16. The lower 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.

[0068] Machine tool 10 also includes a motion mechanism 20, which is designed as a multi-axis motion mechanism. In at least some of the illustrated 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 for conversion to other coordinate systems.

[0069] 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.

[0070] 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 rotated to process the workpiece held by the workpiece holder 30.

[0071] In one embodiment, the workpiece holder 30 is mounted on a single-sided guided cantilever 40, which houses a pivot drive or rotary 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 linear drive 46 via another pivot drive 44, which in turn is 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 linear drive 46 provides a axis of translation that can be referred to as the Y-axis.

[0072] The tool spindle 32 is connected to the frame assembly 16 via linear drivers 50 and 52. Linear driver 50 provides a translation axis, also referred to as the Z-axis. Linear driver 52 provides a translation axis, also referred to as the X-axis. The two linear drivers 50 and 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 related to the concept of machine kinematics.

[0073] In summary, the machine tool 10 provides a compact working space 24. This results in a small overall size, light weight, and low energy demand for the 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 lower frame 14 of the frame 12, respectively, and supported on the rear side of the working space 24, the working space 24 is easily accessible. Therefore, in principle, three sides (the front and two side sides) can be used for horizontal access to the working space 24. Furthermore, in principle, the upper and lower sides of the working space 24 can also be used, at least in a limited manner, for example, for handling coolant, for chip management, and for other purposes.

[0074] Figure 2 A perspective view is used to illustrate the manufacturing system, generally indicated by 60, which houses machine tool 10, which is roughly based on... Figure 1 Design. The manufacturing system 60 includes a rack 62 and a housing 64 designed as a cabinet in this embodiment. The housing 64 may also be referred to as a shell. In the exemplary design, the housing 64 is designed to be approximately one person tall. In this embodiment, the manufacturing system 60 is compactly designed, having a layout comparable to a tall cabinet. This should not be construed as limiting. The rack 62 may also be referred to as the base rack of the manufacturing system 60. Machine tool 10 Figure 1 The frame 12 shown (also called the machine tool frame) is arranged on the frame 62.

[0075] Manufacturing System 60 Figure 2 The design shown includes a lower component 66 and an upper component 68 arranged on the lower component. For example, the lower and upper components house different components of the manufacturing system 60 and spatially separate them from each other. In addition to the machine tool 10, the manufacturing system 60 also includes a device 70 for discharging chips. This device 70 may also be referred to as a chip discharge device. In an embodiment, the lower component 66 includes this device 70. The device 70 provides a chip trolley parking position 72 for the chip trolley (by... Figure 2 (Indicated by the dashed line in the diagram). The device 70 can be closed by the door 76 of the housing 64. In a similar manner, the machine tool 10 (or its working space 24) can be closed by the door 78 of the housing 64.

[0076] Machine tool 10, along with its workspace 24, is attached to the upper component 68 of manufacturing system 60. Therefore, machine tool 10 is positioned at a height convenient for standing or sitting operators. A chip removal device 70 is attached to the lower component 66 of manufacturing system 60. Device 70 is located below the workspace 24 of machine tool 10.

[0077] exist Figure 2In the diagram, the front of the manufacturing system 60 or machine tool 10 is indicated by an arrow marked 84. From the front 84, an operator of the manufacturing system 60 can observe and operate the machine tool 10 and the chip removal device 70, for example, through doors 76 and 78. Figure 2 The diagram also shows a control panel, designated 86, for controlling the manufacturing system 60, which also faces forward 84. The control panel 86 corresponds to and / or is connected to the control device 18. The compactness of the machine tool 10 and the manufacturing system 60 equipped with the machine tool simplifies operation. Operators can view and access relevant components of the manufacturing system 60 from the front side 84.

[0078] Furthermore, the cabinet-like design with lower component 66 and upper component 68 allows the chip trolley parking position 72 to be arranged below the work space 24, even when viewed vertically (see arrow Z in the coordinate system XYZ). Viewed from above, the work space 24 partially or completely covers the chip trolley parking position 72, at least in the exemplary configuration.

[0079] Figures 3 to 5 Other components of the device 70 and their arrangement with the machine tool 10 are shown. Figures 2 to 5 The manufacturing system 60 and its components are shown from the same perspective (obliquely above the front side 84). Figure 2 In the middle, the shell 64 is closed. Figure 3 At least doors 76 and 78 of the casing 64 are open. When door 78 is open, the operator positioned on the front side 84 can access the workspace 24 of the machine tool 10. The workpiece holder 30 and the tool holder 34 are arranged in the workspace 24 and are movable relative to each other.

[0080] When door 76 is opened, device 70 is accessible. Chip trolley 90 is positioned in chip trolley parking position 72 and can be removed from chip trolley parking position 72 as needed. This is, for example, when chip trolley 90 is completely filled with chips and other waste. In an embodiment, chip trolley 90 is at least partially arranged above a KSS-tank 92 for containing cooling lubricant, etc. This may also refer to cooling lubricant or cooling lubricant (KSS) mixed with chips in chip trolley 90 and flowing into KSS-tank 92.

[0081] The working space 24 of the machine tool 10 is connected to the chip trolley 90 via a connector 94. In this way, chips can fall directly from the working space 24 into the chip slide 90 as directly as possible. This is preferably achieved by gravity and does not require an additional (driven) chip conveyor.

[0082] Handle 98 is mounted on chip trolley 90. Connector 94 has handle 102 and locking element 104 for operation purposes. Chip trolley 90 can be pulled out from chip trolley parking position 72 in housing 64 via handle 98. The operating element enables quick and easy replacement or emptying of chip trolley 90. This is achieved by the protruding arrangement of machine tool 10 in upper part 68 of housing 64. This is further facilitated by the compact design of machine tool 10.

[0083] Figure 4 A partial view of the casing 64 is shown, with the door 76 open, to further illustrate the components of the device 70. Figure 4 In this process, the chip trolley 90 is pulled out from the chip trolley parking position 72 within the housing 64. This process is achieved when the connector 94 is in the release position. The connector 94 can move vertically between the release position and the running position, see [link to relevant documentation]. Figure 4 The double arrow is marked with 106. The handle 102 is used for operation. The connector 94 can be locked or locked in the released position by means of the locking element 104.

[0084] The chip trolley 90 provides a receiving portion 110 for the chip basket 112. In the exemplary configuration, the chip basket 112 can be removed from the receiving portion 110. Therefore, the chip trolley 90 can be replaced entirely as needed, i.e., a full chip trolley 90 can be replaced with an empty chip trolley 90. When the chip trolley 90 has been removed from the chip trolley parking position 72, the chip basket 112 can also be easily replaced or emptied. The chip basket 112 has an opening 114 through which chips fall from the workspace 24 into the chip basket 112. For this purpose, the chips pass through the connector 94. Furthermore, in the embodiment, at least one handle 116 is provided for the chip basket 112, so that the chip basket 112 can also be operated independently.

[0085] The chip trolley 90 has a travel mechanism 120 at its lower end, which supports the structure 122. The structure 122 surrounds the receiving portion 110. In the region of the receiving portion 110 for the chip basket 112, the structure 122 is approximately box-shaped and opens upwards. A handle 98 is fixed to the structure 122. The receiving portion 110 is arranged above the KSS-operating section 126. The KSS-operating section 126 is arranged between the travel mechanism 120 and the receiving portion 110. A KSS-discharge line 128 is arranged in the KSS-operating section 126, through which excess coolant lubricant can drip or flow from the chip basket 112 toward the KSS-tank 92. The KSS-operating section 126 includes an operating opening 130 through which at least the KSS-discharge line 128 is accessible; in an embodiment, the KSS-discharge line includes a quick-connect fitting 132.

[0086] In the region of the KSS-operating segment 126, the chip trolley 90 has a rearward-facing frame recess 136. This allows for an advantageous arrangement of the chip trolley 90 relative to the KSS-slot 92 within the housing 64 of the manufacturing system 60. The chip trolley 90 has a circumferential edge 140 towards the connector 94, which is positioned by the connector 94 in the operating position (see...). Figure 9 The chip trolley 90 is connected to the work space 24 in a sufficiently sealed manner for chip discharge.

[0087] exist Figure 4 In this configuration, the KSS-trough 92 is positioned at the lower ground parking position 142. The KSS-trough 92 is specifically positioned below the chip basket 112 when the chip trolley 90 is placed in the chip trolley parking position 72. In this embodiment, the KSS-trough 92 is supported on the travel mechanism 144 and is therefore movable from the lower ground parking position 142. This is simplified by a handle 146. The KSS-trough 92 has a KSS-pipeline 148, which can be connected to a KSS-discharge pipeline 128 when the KSS-trough 92 and the chip trolley 90 are positioned at their respective parking positions 72, 142. The KSS-trough includes a KSS-container 150 into which the KSS-pipeline 148 leads. Compared to the chip basket 112, the KSS-container 150 is designed to be flatter but has a larger bottom surface. In this way, both the chip basket 112 and the KSS-container 150 have sufficient capacity.

[0088] Figure 5 The illustrations in the diagrams are based on Figures 2 to 4 The diagram shows that, in Figure 5 The casing 64 is not shown in the image. Figure 5 The image shows at least segmented sections of the machine tool 10's workspace 24 and the workspace panel 156 surrounding it. The workspace 24 has a chip discharge opening 158, which, in an embodiment, is designed as a chip funnel located at the lower end of the workspace panel 156. A connector 94 is coupled to and at least segmented around the chip discharge opening 158.

[0089] The connector 94 carries a seal 160 at its end facing the chip trolley 90, which in the operating position (see...) Figure 9 The seal 160 is placed on the surrounding edge 140 of the chip trolley 90. This achieves a sufficiently sealed connection between the connector 94 and the chip trolley 90. It goes without saying that the seal 160 can also be arranged within the chip trolley 90 in principle.

[0090] The KSS-tank 92 with KSS-container 150 can be functionally connected via KSS-pipeline 148 to the KSS-discharge pipe 128 in the KSS-operation section 126 of the chip trolley 90. The KSS-container 150 is at least segmentally (in top view) U-shaped, such that it surrounds at least one recess 166 into which the travel mechanism 120 of the chip trolley 90 can (e.g., on one side in a trajectory) drive. For example, if the travel mechanism 120 of the chip trolley 90 is U-shaped in top view, the KSS-container 150 is also U-shaped in top view, but oriented with a 180° pivot. The two "U-shapes" can engage with each other accordingly. This reduces vertical space requirements.

[0091] In one embodiment, the KSS-tank 92 includes a guide 168 for the travel mechanism 120 of the chip trolley 90. In other words, in one embodiment, the KSS-container 150 forms at least a portion of the chip trolley parking position 72. Furthermore, the KSS-container has a level indicator... Figure 5 The Chinese character is marked with 170. Figure 5 The diagram also shows a lateral guide 174 for the KSS-tank 92, which is connected to the frame 62 ( Figure 5 (Not shown) are fixedly connected and form the boundary of the lower ground parking position 142 for the KSS-tank 92.

[0092] Figure 6 and Figure 7 A vertical view (from below) of a manufacturing system 60 having a chip trolley 90 and a KSS-trough 92 is shown. Figure 6 In this configuration, the chip trolley 90 and the KSS-trough 92 are located in their respective parking positions 72 and 142. The chip trolley 90 and the KSS-trough 92 are integrated into a housing 64 that is housed on or by the frame 62 (encircling or covering it). Figure 7 In the middle, when door 76 is opened, the chip trolley 90 and KSS-trough 92 are removed from their parking positions 72, 142. This is done from the front of manufacturing system 60, see [link to documentation]. Figure 2 Arrow 84 in the image.

[0093] In one embodiment, the traveling mechanism 120 of the chip trolley 90 has four first rollers 178 forming a first surface 182, see [link to previous embodiment]. Figure 6Additionally, in this embodiment, the travel mechanism 144 of the KSS-tank has four second rollers 180 forming a second surface 184. The first surface 182 and the second surface 184 are defined, for example, by the corresponding connection points between the first roller 178, the second roller 180, and the travel mechanisms 120 and 144. The first surface 182 and the second surface 184 are horizontally oriented. The first surface 182 of the chip trolley 90 is at least partially (or, if necessary, completely) arranged within the second surface 184 of the KSS-tank 92. This demonstrates an overlapping (or, if necessary, overlapping) design with advantageous full utilization of a given structural space (the mounting surface of the manufacturing system 60).

[0094] Figure 7 A guide 168 is shown that provides a KSS-trough for the travel mechanism 120 of the chip trolley 90. Furthermore, a recess 166 constructed in the KSS-container 150 is shown. There, two first rollers 178 of the travel mechanism 120 of the chip trolley 90, arranged sequentially to each other, can drive into. Additionally, Figure 7 A guide 174 for connection to the rack 62 is shown for the KSS-tank. The guide 174 demarcates the lower ground parking position 142. Figure 7 In the diagram, the double arrow marked 186 indicates the corresponding travel directions of the chip trolley 90 and the KSS-trough 92 during entry and exit.

[0095] Figure 8 and Figure 9 A sectional view is used to show the release position of connector 94. Figure 8 ) and running location ( Figure 9 Connector 94 is positioned above the chip trolley 90 and below the workspace 24, see [reference needed]. Figure 9 The vertical Z-axis is defined. A chip discharge opening 158 in the workspace leads to a connector 94. The edge 188 of the connector 94 surrounds or overlaps with the chip discharge opening 158. In this embodiment, an intermediate member 190 is also provided, which is part of the chip discharge opening 158. Generally, the chip discharge opening 158 is generally funnel-shaped and gradually tapers towards the chip trolley 90.

[0096] The locking element 104 is accommodated on the connector 94, and the locking element is in Figure 8 The connector 94 is engaged in the notch 192 of the chip discharge opening 158 or the intermediate piece 190. In this way, the connector 94 is secured in... Figure 8 The release position is shown in the diagram. Figure 9In the shown operating position, the locking element 104 disengages from the notch 192. In this state, the connector 94 can move vertically (see double arrow 106). The connector 94 can move towards the chip trolley 90 by its own weight. This movement can also be achieved via the handle 102. The connector 94 forms a channel 194 for chip transfer. According to... Figure 8 and Figure 9 In one embodiment, a lifting guide 196 is provided to simplify vertical adjustment movement, through which the connecting member 94 is pushed vertically along the side of the frame.

[0097] A flange 202, specifically a circumferential flange 202, is provided at the connector 94 in the direction of the chip conveyor 90. The flange 202 carries the seal 160. According to... Figure 9 In its operating position, the connector 94 is positioned securely on the surrounding edge 140 of the chip trolley 90 using the seal 160. Similarly, the (lower) opening 204 of the connector 94 at least partially engages with the opening 114 of the chip basket 112. In this way, it is ensured that chips are reliably guided along the channel 194 through the connector 94 into the chip basket 112 of the chip slide 90 along the chip discharge path 210 between the workspace 24 and the chip slide 90.
