Description

Technical Field

[0001] This invention relates to a replacement system for replacing a mixer, preferably for a multi-component adhesive. The invention also relates to a corresponding replacement method. Background Technology

[0002] Mixing devices with mixers and manipulating mechanisms, such as robots for moving the mixing device, are various embodiments known in the prior art. The mixing device is used to mix the different components (e.g., hardener and adhesive) of a two-component adhesive and apply the mixed two-component adhesive, for example, to a vehicle component. One problem, for example, is that after a certain replacement interval or after significant wear, a malfunctioning mixer must be replaced with a new one. These replacements are typically performed manually by workers within the application unit, thus in a potentially hazardous area. On the one hand, there is a risk of personal error. On the other hand, there is a risk of worker exposure to hazardous substances, for example. Manual replacement is specifically performed in the following manner: loosening the fastening screws, removing the mixer to be replaced, inserting the new mixer, and installing and tightening it by the fastening screws. Summary of the Invention

[0003] One object of the present invention is to provide an improved and / or alternative possibility for replacing, for example, a dysfunctional mixer.

[0004] This objective can be achieved through the features of the independent claims. Other advantageous embodiments of the invention are disclosed in the sub-claims and in the following description of preferred exemplary embodiments of the invention.

[0005] The present invention relates to a preferred automatic replacement system for replacing a mixer (e.g., a mixer that specifically needs to be replaced due to functional impairment).

[0006] The replacement system includes a mixing device having a mixer for mixing a multi-component applicator (e.g., an adhesive (preferably a resin) or a coating) of at least two different components, wherein the properly mixed multi-component applicator is used for application to the workpiece.

[0007] The workpiece is preferably a motor vehicle component, such as a motor vehicle body and / or its additional parts.

[0008] Multicomponent applicators are preferably multicomponent adhesives (e.g., 2C adhesives, preferably resins) or multicomponent coatings (e.g., 2C coatings). For example, a multicomponent applicator may include at least one hardener and at least one adhesive.

[0009] The replacement system includes a manipulator (e.g., a robot preferably having at least three degrees of freedom) for moving the mixing device, particularly moving the mixing device along the workpiece.

[0010] The replacement system is characterized by including a replacement station (e.g., a replacement warehouse).

[0011] This replacement station is specifically designed for automatically placing a mixing device with a mixer to be replaced (e.g., replacing all or part of it) and / or, for example, automatically receiving a mixing device with a new mixer (e.g., a completely or partially new mixer).

[0012] Therefore, this replacement system enables a particularly automated replacement process.

[0013] For example, on the one hand, the replacement system allows a mixing device with a mixer to be replaced to be placed in a replacement station, preferably in an automatic manner.

[0014] On the other hand, for example, the replacement system allows the replacement station to be equipped (e.g., manually or automatically) with one or more mixing units with new mixers, preferably equipped during operation (e.g., production and / or application) and / or without the need for workers to enter the application unit.

[0015] Therefore, one advantage of this replacement system is that it can, for example, store one or more mixing units with new mixers.

[0016] The mixing device with the new mixer is preferably able to be automatically picked up from the change station by the operating device, so that the application process can be carried out with the mixing device with the new mixer.

[0017] The replacement station can be located, particularly within the reach of the operating device. The operating device can be configured, particularly automatically, to locate the mixing device with the mixer to be replaced in the replacement station, and / or preferably automatically pick up the mixing device with the new mixer from the replacement station.

[0018] The replacement station is preferably configurable as movable (e.g., manually and / or electrically), such as rotatable and / or translational.

[0019] Preferably, the replacement station is mobile, for example, mobile in an automatic manner, and preferably controlled by a control device.

[0020] The replacement system may have a drive device (e.g., a motor, particularly an electric motor) to move the replacement station, preferably in an automatic manner, such as by rotation and / or translation.

[0021] The actuation device is preferably arranged in the application unit, which is, for example, closed or at least partially open, particularly in which a multi-component application agent can be applied to the workpiece.

[0022] The replacement station may be arranged at least partially within the application unit and / or at least partially outside the application unit.

[0023] The replacement station can be movable, preferably for example, to move at least one mixing device with a new mixer at least partially into the application unit, and / or for example, to move at least one mixing device with a mixer to be replaced at least partially outside the application unit.

[0024] For example, a replacement station may include receivers for at least two mixing devices, such as at least one receiver for a mixing device with a mixer to be replaced and at least one receiver for a mixing device with a new mixer.

[0025] The receiver can be configured as, for example, a recess, a pocket, or other means of containment.

[0026] The contour (especially the inner contour) of the receiver may correspond at least partially to the contour (especially the outer contour) of the mixing device, preferably such that the mixing device can be fixed, particularly with respect to its circumference and / or axial direction, preferably in a form-fitting manner.

[0027] For example, a changeover station may include a turntable and / or may be movable along the track system.

[0028] It is possible that the mixing device and / or replacement inserts (e.g., strips, pipe piles, reducing sleeves, etc.) include at least two separate lines, preferably leading to the mixer, for example, in order to guide at least two different components separately from each other.

[0029] The cross-sections of at least two independent pipes can be narrowed toward the mixer.

[0030] For example, at least two separate conduits may extend at least partially parallel to each other and / or at an acute angle in the direction toward the mixer.

[0031] Replacement inserts or mixing devices may generally include, for example, a tapered section that tapers particularly toward the mixer. The tapered section preferably forms the tip of the replacement insert and / or is at least partially exposed within the mixing device.

[0032] The reduced section can be formed, for example, as part of a replacement insert or as part of the base portion of a mixing device.

[0033] The tapered section preferably comprises a shape that is substantially conical or conical, and for example has at least partially flat, recessed, and / or convex side surfaces.

[0034] It is possible that at least two independent pipes, preferably having two independent outlet openings, open in the narrow section.

[0035] It is possible that at least one bushing (e.g., a replacement bushing) is housed in a replacement insert, particularly in a releasable manner, and that at least one bushing may include at least two separate lines or at least one of at least two separate lines.

[0036] For example, at least two separate lines may extend at least to the mixer (e.g., inside the mixer or substantially adjacent to an upstream opening of the mixer), preferably such that mixing can only begin inside the mixer.

[0037] The reduced section may, for example, protrude from the base portion of the mixing device (preferably at least to the mixer) and / or protrude (preferably at least partially exposed) into the application tube of the mixing device.

[0038] Replacement inserts may include at least a portion of a basic structure that is substantially cylindrical, conical, and / or truncated conical.

[0039] For example, the replacement insert, at least one bushing, base portion, application tube, and / or mixer can be made of plastic.

[0040] The mixing device may include a connecting surface, particularly an internal connecting surface, for releasable connection to the tapered section. The connecting surface is preferably substantially conical and, for example, has flat, recessed, and / or convex side surfaces.

[0041] The tapered sections and connecting surfaces can, in particular, have substantially the same angular position in their contact areas, thus preferably ensuring a tight connection through their structural shape, especially during mixer replacement.

[0042] The reduced section, especially in its circumferential direction, can be substantially tightly and / or prestressedly connected to the connecting surface.

[0043] The operating device can carry the application head, for example, indirectly or directly.

[0044] The application head is specifically designed to provide at least two different application agents to a mixing device and / or to install the mixing device, particularly in a releasable manner.

[0045] For example, the application head may be part of an applicator having a metering device for metering at least two different components.

[0046] The mixing device preferably includes an interface for releasable connection with the application head. Therefore, the mixing device and the application head may particularly include mounting means for releasable connection with each other.

[0047] The operating device can be configured, for example, to place a mixing device with a mixer to be replaced in a replacement station, particularly by moving the application head (e.g., rotating and / or translating) to release the interface, so that the mixing device with the mixer to be replaced can be placed in the replacement station.

[0048] Alternatively or additionally, the operating device may be configured, for example, to connect the application head to a mixing device with a new mixer placed in a changeover station, and / or in particular to move (e.g., rotate and / or translate) the application head such that the interface is closed, so that the mixing device with the new mixer can be picked up from the changeover station.

[0049] The interface is preferably released and / or closed by at least one opening and / or closing movement that can be generated by a manipulator (e.g., by applying head transmission).

[0050] The manipulation device may include, for example, a robot with at least three degrees of freedom, particularly an articulated robot or a gantry robot.

[0051] For example, the robot may be a robot with multiple rotatable robotic arms, preferably robotic wrists with at least 2 or 3 degrees of freedom.

[0052] The mixing device preferably includes a base portion and / or a strip-shaped application tube. The mixing device is preferably formed as an assembly, particularly an assembly including a mixer and a base portion and / or an application tube.

[0053] The base portion and the application tube can be installed on each other, preferably in a releasable manner.

[0054] The application tube and / or base portion can be made of, for example, metal and / or plastic.

[0055] The mixer can be housed within an application tube, for example, in a releasable manner, and particularly replaceably within an application tube. The application tube can, in particular, form a support tube for the mixer. For example, the mixer can also extend into a base portion.

[0056] The base portion preferably includes an interface for releasable connection with the application head.

[0057] The mixer is preferably a spiral mixer (e.g., a spiral mixer or a Kenics mixer) and / or a static mixer.

[0058] For example, a mixer may include at least one helical, screw-shaped, sheet-shaped, and / or lattice-shaped mixing element, which may extend along an application tube, for example.

[0059] Replacing inserts can result in the replacement of individual components, especially when inserts may be replaced due to adhesion, blockage, or wear during or on the replacement process.

[0060] The insert can be inserted (especially at least partially) into, for example, a mixing device (quickly inserted into the base portion and / or the application tube) and / or an application head, preferably in a releasable manner, and especially in a replaceable manner.

[0061] For example, replacing the insert can extend the interface.

[0062] For example, the replacement insert to be replaced can be removed and a new replacement insert can be inserted through the front side of the mixing device and / or the front side of the application head.

[0063] Replacement inserts may include, for example, a cylindrical basic structure, which preferably has different outer diameters, wherein, for example, the outer diameter facing the application head may be larger than the outer diameter facing the mixer.

[0064] The replacement insert is preferably configured to be inserted into the mixing device and / or application head substantially precisely and / or without dead zones.

[0065] For example, the replacement insert may extend substantially coaxially with the mixer, base portion, application tube, and / or application head. Alternatively or additionally, the replacement insert may be arranged in a substantially central position within, for example, the mixing device and / or application head.

[0066] The mixing device (particularly the base portion and / or the application tube) and / or the application head may include a receiver for receiving the replacement insert, for example, receiving it precisely and / or substantially without dead zones.

[0067] It is possible that the replacement insert preferably includes at least one fastening recess (e.g., groove, hole, cavity, etc.) on its side surface and provides at least one particularly pluggable and / or unthreaded retaining element (e.g., at least one retaining bolt or fixing bracket, particularly a spring bracket) to facilitate securing the replacement insert by means of at least one fastening recess.

[0068] The application head may include at least one fastening opening (e.g., a through hole), preferably having at least one fastening opening on its side surface, wherein at least one retaining element is configured to engage with at least one fastening recess and at least one fastening opening.

[0069] At least one retaining element can engage with the replacement insert, particularly from the outside (e.g., by applying a head).

[0070] For example, at least one retaining element may include at least one bolt or bracket (e.g., a spring bracket) for inserting and withdrawing at least one fastening recess and at least one fastening opening.

[0071] At least one fastening recess, at least one fastening opening, and / or at least one retaining element can preferably be formed in a threadless form.

[0072] The replacement system may include, for example, control devices.

[0073] The control device may be configured to, for example, ensure that, upon reaching the replacement time interval and / or upon (preferably automatically and / or based on sensors) detecting (e.g., wear, damage, and / or functional impairment) of the mixer to be replaced, a mixing unit with the new mixer is placed in the replacement station and / or a mixing unit with the new mixer is removed from the replacement station.

[0074] To detect a mixer to be replaced, the replacement system may include, for example, a sensor system. For instance, the sensor system may be configured to detect the applied result, from which a conclusion can be drawn about which mixer should be replaced.

[0075] For example, the control device can be configured to control the movement of the changing station and / or the operating device, particularly the movement performed during the changing process.

[0076] For example, the control device may be configured to ensure that the replacement station causes at least one mixing device with a new mixer to enter the application unit at least partially, and / or at least one mixing device with a mixer to be replaced to leave the application unit at least partially.

[0077] For example, a replacement station can be equipped with any number of receivers (e.g., drop positions) such that these receivers can preferably be completely replaced once at longer time intervals, depending on the quantity.

[0078] It should be mentioned that the present invention is particularly applicable to the casting of two-component adhesives and / or thermally conductive media.

[0079] It should also be mentioned that the present invention may include a replacement system for, for example, partially or fully automating the replacement of a mixer (e.g., including a base portion and / or an application tube).

[0080] For example, a mixing device having a mixer to be replaced, an optional application pipe, and an optional base portion can be placed in a replacement station, wherein the mixer, the optional application pipe, and the optional base portion can be replaced.

[0081] For example, the mixer and application tube to be replaced, as well as the optional base section, can be replaced (e.g., disposed of).

[0082] However, it is also possible, for example (especially only) the mixer to be replaced can be replaced (e.g., disposed of), but the application tube and / or base section can preferably be reused by a new mixer.

[0083] For example, it is possible that the mixer and application tube to be replaced can be replaced (e.g., disposed of), but, for example, the base portion can preferably be reused with a new mixer and / or a new application tube.

[0084] Of course, the mixing device with the mixer, application tube and base section can also be replaced together, and replaced by a mixing device with a new mixer, a new application tube and a new base section.

[0085] Replacement of the mixing device, mixer, application tube and / or base section can be performed quickly, either manually or automatically, especially outside the application unit.

[0086] For example, the application unit can be laterally defined by one or more fences, barriers, walls, window panes, etc.

[0087] The present invention also includes a preferred method for automatically changing the mixer. This changing method is preferably performed using the changing system disclosed herein.

[0088] The replacement method includes: a mixing device having a mixer, wherein at least two different components of a multi-component applicator for application to a workpiece can be mixed by the mixing device; and a manipulating device that can preferably move the mixing device along the workpiece.

[0089] The replacement method is characterized in that, at the replacement station, the mixing device with a mixer (especially the mixer to be replaced) is preferably placed down automatically, and / or, for example, the mixing device with a (especially new) mixer is preferably received automatically.

[0090] The preferred exemplary embodiments and features of the invention described above can be readily combined with each other. Other advantageous further embodiments of the invention are disclosed in the appended claims, or arise from the following description of preferred exemplary embodiments of the invention taken in conjunction with the accompanying drawings.

[0099] The preferred exemplary embodiments of the invention described with reference to the figures partially overlap, wherein similar or identical parts have the same reference numerals, and can also be interpreted with reference to the description of other exemplary embodiments. For clarity, not all parts in all figures are provided with reference numerals. Detailed Implementation

[0100] Figure 1 A replacement system 100 for convenient, partially or fully automated replacement of a mixing device 10 according to an exemplary embodiment of the present invention is shown.

[0101] The replacement system 100 includes a mixer 13 (e.g., Figure 2 The mixing apparatus 10 is used to mix at least two different components (e.g., a hardener and an adhesive) to obtain a multi-component applicator, wherein the mixed multi-component applicator is used to apply to a workpiece 200. The multi-component applicator is preferably a 2C adhesive (e.g., comprising a resin).

[0102] The replacement system 100 also includes a manipulator 20 (e.g., an articulated robot) for moving the mixing device 10 along the workpiece 200.

[0103] The operating device 20 advantageously carries the application head 60 upstream of the mixing device 10, through which at least two different components can be supplied to the mixing device 10.

[0104] The mixing device 10 includes an interface C through which the mixing device 10 is releasably connected to the application head 60.

[0105] Therefore, the application head 60 is used to provide at least two different components to the mixing device 10 and to releasably mount the mixing device 10. The application head 60 can be conveniently connected to the operating device 20, either indirectly or directly.

[0106] The manipulating device 20, together with the application head 60 and the mixing device 10, is arranged in the application unit 40, so that a multi-component application agent can be applied to the workpiece 200 in the application unit 40.

[0107] A key feature is that the replacement system 100 represents a system for conveniently and partially or fully automatically replacing a mixer 13 that is functionally particularly damaged. The replacement system includes a replacement station 30, which is specifically for automatically placing a mixing device 10 with a mixer 13 to be replaced, and preferably specifically for automatically receiving a mixing device 10 with a new mixer 13. Figure 1 In an exemplary embodiment, the changing station 30 is configured as a turntable rotatable about a rotation axis R, wherein a drive unit can be provided to move the changing station 30 in an automatic manner.

[0108] The replacement station 30 is preferably partially disposed within and partially disposed outside the application unit 40. However, the replacement station may also be configured, for example, to move completely into and completely out of the application unit 40.

[0109] The replacement station 30 includes at least two receivers 31, 32 for at least two mixing devices 10, namely at least one receiver 31 for at least one mixing device 10 having a mixer 13 to be replaced, and at least one receiver 32 for at least one mixing device 10 having a new mixer 13.

[0110] The inner contours of receivers 31 and 32 may correspond to the outer contours of mixing device 10, preferably such that mixing device 10 can be fixed and / or shaped-fitted in the inner contours 31 and 32 relative to its circumferential direction, thereby allowing interface C to be released or closed, for example, by applying at least one rotational movement of head 60, which may be generated by actuation device 20.

[0111] On one hand, the operating device 20 can be configured to place a mixing device 10 with a mixer 13 to be replaced in the changing station 30 and move (e.g., rotate and / or translate) the application head 60 so that the interface C can be released and the mixing device 10 with the mixer 13 to be replaced can be placed in the changing station 30.

[0112] On the other hand, the operating device 20 can be configured to connect the application head 60 to the mixing device 10 with the new mixer 13 placed in the changing station 30, and move (e.g., rotate and / or translate) the application head 60 so that the interface C can be closed and the mixing device 10 with the new mixer 13 can be removed from the changing station 30.

[0113] Therefore, the release and closure of interface C, particularly the installation of the mixing device 10 with the new mixer 13 onto the application head 60, and the removal of the mixing device 10 with the mixer 13 to be replaced from the application head 60, are preferably carried out by the opening and closing movement of the operating device 20, thereby by the opening and closing movement of the application head 60.

[0114] Figure 1 As shown, the change station 30 may be equipped, for example (e.g., manually or automatically) with one or more mixing units 10 having new mixers 13, particularly during operation (e.g., production and / or application), in particular, where workers do not have to enter the application unit 40.

[0115] Therefore, its advantage is that, for example, manual operation is not required in the application unit 40 for mixer replacement, thus avoiding long interruptions to the production process, especially due to mixer replacement, in hazardous areas, and / or preventing individual errors during mixer replacement. To minimize downtime for manual mixer replacement, workers typically work under time pressure, thus increasing their stress levels, which is associated with increased susceptibility to errors.

[0116] Another advantage is that, for example, unforeseen and necessary mixer replacements can be performed automatically (e.g., detected by a sensor system) and are therefore preferably performed quickly. In the event of unplanned wear, damage, or other issues with mixer 13, mixer replacement can be performed automatically and flexibly in a short time, especially without the need for worker intervention.

[0117] The setup time for the new mixer 13 can be scheduled, for example, by planning downtime.

[0118] Figure 2 Specifically shown is the application head 60 and the mixing device 10 with the mixer 13 to be replaced in the replacement station. Figure 2 (left side) and mixing device 10 with new mixer 13 Figure 2 (The right side of the middle).

[0119] Figure 2 The diagram shows an application head 60 (shown schematically only) carried by the manipulation device 20 in a mutually released state (interface C released) and a mixing device 10 with a mixer 13 to be replaced.

[0120] The mixing device 10 may advantageously include a base portion 11 and an application tube 12, wherein a mixer 13 for mixing at least two components is at least substantially housed within the application tube 12. The mixer 13 is preferably a static mixer, particularly a spiral mixer. For example, the mixer 13 may be housed in the application tube 12 in a releasable or non-releasable manner.

[0121] Interface C can be advantageously formed on base portion 11.

[0122] The mixing device 10 is preferably formed as an assembly, which may include a mixer 13 and, in particular, an application tube 12 and / or a base portion 11.

[0123] The mixing device 10, particularly the base portion 11, includes at least two separate conduits 51, 52 to guide at least two different components to flow separately to the mixer 13.

[0124] At least two independent pipes 51, 52 can be integrated, for example, into the base portion 11.

[0125] However, at least two separate conduits 51, 52 may also be housed in a separate replaceable insert 50 (e.g. Figure 9 and 10 The insert 50 can be releasably inserted into the mixing device 10, preferably into the application head 60, and particularly into the replacement part.

[0126] Therefore, replacing insert 50 forms a replaceable component, especially because, for example, adhesion, blockage or wear may occur in or on insert 50.

[0127] Figure 3 Specifically shown is the application head 60 and the mixing device 10 with the mixer 13 to be replaced in the replacement station. Figure 2 (left side) and mixing device 10 with new mixer 13 Figure 2 (The right side of the middle).

[0128] Figure 3 The diagram shows the application head 60 (shown schematically only) carried by the operating device 20 in the mutually installed state (interface C closed) and the mixing device 10 with the new mixer 13.

[0129] Figure 4 The process steps that can be performed by replacing system 100 are shown.

[0136] S4 represents the rotation of the changing station;

[0137] S5 represents disposal or removal of the mixer to be replaced (and optionally the base section and / or application tube);

[0138] S6 represents refitting and first replacement;

[0139] S7 represents a single replacement;

[0140] S8 represents the rotation of the changing station.

[0141] Figure 5 A detailed perspective view of the mixing device 10 and a portion of the application head 60 is shown, in which... Figure 6 The relevant cross-sectional view is shown.

[0142] The application tube 12 is in particular a strip-shaped member, which has an outlet opening (e.g., a nozzle) for mixing multi-component application agents.

[0143] Figure 5 and Figure 6 The mixer 13, not shown, can be housed in the application tube 12, for example, in a releasable manner.

[0144] The base portion 11 and the application tube 12 can be mounted to each other, for example, in a releasable manner.

[0145] Therefore, it is possible to replace, for example, only the mixer 13 to be replaced (e.g., disposed of), but, for example, the base portion 11 and / or the application tube 12 can be reused with a new mixer 13. For example, the replacement of the mixer 13 can be carried out manually by a worker or in an automated manner, especially outside the application unit 40.

[0146] However, it is also possible, for example, that the mixer 13 and application tube 12 to be replaced can be replaced (e.g., disposed of), but the base portion 11 can be reused, for example. For example, the replacement of the mixer 13 and application tube 12 can be carried out manually by a worker or in an automated manner, particularly outside the application unit 40.

[0147] The mixer 13, base portion 11, and application tube 12 to be replaced can also be replaced (e.g., disposed of), thereby replacing the entire mixing unit 10, in particular, with, for example, a brand new mixing unit 10. The replacement of the essentially complete mixing unit 10 can be carried out manually or automatically by a worker, particularly outside the application unit 40.

[0148] Figure 7 and 8Different perspective views are shown, particularly of the base portion 11 and a portion of the applied head 60.

[0149] Figure 7 and Figure 8 A tapered section 53, for example, inclined toward the mixer 13, is shown. It may be part of the replacement insert 50, but may also be part of the base portion 11. The tapered section 53 may be advantageously shaped into a conical tip or a rounded tip.

[0150] At least two independent pipes 51, 52 open through at least two independent outlet openings 54, 55 in the narrow section 53, and thus preferably extend at least to the mixer 13, and preferably make mixing begin only in the mixer 13.

[0151] The tapered section 53 advantageously extends from the base portion 11, and thus can preferably extend at least partially exposed into the application tube 12, which in... Figure 7 and Figure 8 Not shown in the image.

[0152] Figure 9 and 10 Different views are shown, particularly of the base portion 11, the replacement insert 50, and a portion of the application head 60.

[0153] The mixing device 10, particularly the application tube 12, may include a generally tapered internal connection surface 14 for releasable connection (particularly contact) with the tapered section 53.

[0154] The tapered section 53 and the connecting surface 14 may have the same angular position (e.g., plane, concave and / or convex) at least in their contact area, thereby ensuring a substantially tight connection between the tapered section 53 and the connecting surface 14, especially a tight connection during mixer replacement.

[0155] It is especially desirable if the tapered section 53 is prestressed and securely connected to the tapered connecting surface 14.

[0156] At least two separate conduits 51, 52 may include, for example, a narrowed channel cross-section toward the mixer 13, and the at least two separate conduits extend, for example, at least partially parallel or at an acute angle to each other.

[0157] exist Figure 9 and Figure 10 In the exemplary embodiment shown, at least two independent conduits 51, 52 are integrated into a separate replacement insert 50. Here, for example, at least one bushing (e.g., a replacement bushing) may preferably be releasably housed in the replacement insert 50, and the at least one bushing includes at least two independent conduits 51, 52 or at least one of at least two independent conduits 51, 52.

[0158] Bushings with different inner diameters can be provided, so that, for example, they can respond to different viscosities of at least two different components, and the pressure can be adjusted, for example, by reducing the inner diameter.

[0159] For example, the replacement insert 50 can be configured to be inserted into the mixing device 10 on one hand (particularly the base portion 11 and / or the application tube 12) and, preferably, releasably into the application head 60 on the other hand, so that it can be replaced. Thus, the replacement insert 50 can extend, for example, through the interface C.

[0160] A tapered section 53 having two outlet openings 54, 55 extends from the base portion 11 of the mixing device 10 and advantageously extends into the application tube 12 of the mixing device 10, thereby exposing the two outlet openings 54, 55.

[0161] Having sufficient guide length within the application head 60 and / or within the mixing unit 50 for replacing the insert 50 particularly helps to maintain the tool center point (TCP).

[0162] For example, the replacement insert 50 includes at least one fastening recess 56 on its side surface, providing at least one preferred pluggable retaining element 57 (e.g., bolt or bracket) to releasably secure the replacement insert 50 to or within the application head 60 via at least one fastening recess 56.

[0163] The application head 60 may include, for example, at least one fastening opening 58 (e.g., a through hole) on its lateral surface, wherein at least one retaining element 57 is configured to engage with at least one fastening recess 56 and at least one fastening opening 58.

[0164] At least one retaining element 57 may engage with the replacement insert 50, for example, from the outside via an application head 60, and at least one retaining element may include, for example, at least one bolt or bracket, for insertion into and withdrawal from at least one fastening recess 56 and at least one fastening opening 58.

[0165] The fastening recess 56, the retaining element 57, and the fastening opening 58 are preferably formed in a threadless form.

[0166] This makes replacing insert 50 particularly simple, safe, and quick.

[0167] The replacement system 100 may include, for example, a control device configured to ensure that the mixing unit 10 with the mixer 13 to be replaced is placed in the replacement station 30 after a suitable predetermined replacement interval has been reached and / or after the mixer 13 to be replaced is detected based on a sensor, and preferably, the mixing unit 10 with the new mixer 13 is removed from the replacement station 30.

[0168] The control device can also be configured to control the movement of the changing station 30 and the operating device 20 to carry out the changing process.

[0169] It should also be mentioned that the application head 60 or mounting plate can be configured to mount the 2C mixer changer onto the application head 60, in particular to directly mount a static mixer with a bracket and support tube, or to mount an SAE flange that can connect to a hose.

[0170] This invention is not limited to the preferred exemplary embodiments described above. Instead, numerous variations and modifications are possible, which also utilize the concepts of this invention and are therefore within the scope of protection. Furthermore, this invention also claims protection for the subject matter and features of sub-claims unrelated to the mentioned features and claims.
