Definitions
- the following disclosure relates to a coupling device for connecting elongate hollow bodies in a mounting system and a mounting system comprising such a coupling device.
- hollow bodies for example in the form of hoses, pipes or channels used for a variety of purposes. Often they serve to transport fluids, components or, when receiving appropriate lines, also power and / or data between different areas and units of the mounting system.
- the hollow body is subject to constant wear and must therefore be replaced regularly as part of maintenance. Since the hollow bodies are usually guided over long distances to or through the mounting system and in this case also have a complex course and can be fastened at several points, it can be extremely complicated to carry out such an exchange. Furthermore, in the case of wear in only a comparatively small area, often the entire hollow body has to be exchanged, which is correspondingly cost-intensive.
- a coupling device for connecting elongated hollow bodies in a mounting system comprising: a first receiving opening for receiving a first elongated hollow body and a second receiving opening for receiving a second elongated hollow body, wherein the receiving openings are arranged relative to each other, that the first and second elongated hollow body can be coupled to one another after insertion into the respective receiving openings.
- the coupling device may generally be positioned at an arbitrary position along the course of travel of the hollow bodies in the mounting system, for example centrally between a start and a finish of the track.
- the first elongated hollow body of extend the distance beginning (or from a first port) to the coupling device and the second elongated hollow body may extend between the coupling device and the end of the travel (or up to a second port).
- the two elongate hollow bodies can be connected in such a way that a continuous course and optionally a continuous conveyability of fluids or components through the hollow bodies from the first to the second connection can be achieved.
- an elongated hollow body can be understood to mean any hollow body whose axial extent exceeds the cross-sectional dimensions. Examples include hoses, pipes and elongated channels or shafts.
- the hollow body is flexible, for example, and may generally be made of a plastic material.
- the hollow body may further be formed in one piece or composed of several individual components and / or layers.
- the hollow body may have a casing.
- the elongate hollow bodies may be rivet tubes or so-called rivet cores, and the mounting system may comprise an industrial robot and a rivet storage unit which can be connected by means of the rivet hoses and via the coupling device.
- the receiving openings may have any cross-sectional profile and be formed generally in opposite areas of the coupling device. Furthermore, the receiving openings can define or be arranged along a connecting axis, wherein the hollow bodies can be introduced into the coupling device along the connecting axis in order to be coupled to one another. Coupling may be understood as meaning a (indirect or direct) connection of the two hollow bodies which permits the above-described continuous course or the continuous conveyability by means of and through the two hollow bodies. In particular, in this case, a contact between the hollow bodies are constructed. According to a variant, the hollow bodies can be introduced with open ends into the respective receiving openings, wherein the open ends can then be coupled to each other and in particular brought into contact. With In other words, the hollow bodies can be coupled to one another by pushing together or at least opposing arrangement of open cross-sectional areas and / or end-face areas.
- At least one of the receiving openings comprises an exchangeable adapter piece, which is designed to receive an elongated hollow body having predetermined cross-sectional dimensions.
- the adapter piece can generally be formed as a separate component and if necessary, in particular depending on the used hollow body, are arranged in the coupling device. For this purpose, it can be inserted into the receiving openings, screwed thereto and positively or otherwise releasably connected, so that the elongated hollow body can be inserted into the receiving opening and the adapter piece arranged therein.
- the adapter piece may further comprise an opening, bore or an inner profile.
- the adapter piece can generally be formed in one piece. Likewise, the adapter piece may be formed in several parts and in particular in two parts, wherein the individual components of the adapter piece can be selected depending on the current dimensions of the hollow body and connected to each other.
- the adapter piece can also be designed in such a way and in particular be profiled in such a way that it encloses the associated elongate hollow body at least in sections substantially in a form-fitting manner.
- the adapter piece may be made of a plastic material, in particular a slightly flexible material, but substantially fixed dimensions of the adapter piece are preferred and in particular the internal profile dimensions (i.e., no manual adjustability via threaded arrangements or the like).
- the coupling device comprises an adapter piece per receiving opening, wherein the adapter pieces can be designed, for example, to receive similarly dimensioned and / or profiled hollow bodies.
- the adapter piece allows the coupling device to be flexibly connected to various types of elongate hollow bodies without the need for additional separate arrangements on the coupling device itself. Rather, it may be sufficient to select only a matching adapter piece and arrange in the receiving opening.
- the coupling device can thus essentially remain permanently and unchanged in the mounting system. ben, although the cross-sectional dimensions of the elongated hollow body may change depending on the current assembly task (for example, because different sized rivets must be transported by the hollow body). This increases the flexibility of the mounting system and reduces the Umrüstaufwand, while the generally achievable with the coupling device advantages can be maintained (see above discussion to reduced maintenance costs, etc.).
- the coupling device further comprises a base body, in which the first and second receiving openings are formed, wherein the receiving openings are connected to each other via at least one connecting channel in the base body.
- the main body may be substantially integrally formed or composed of several individual components.
- the base body comprises a compressed air-resistant and possibly also not deformable material.
- the main body is designed as a metal block and in particular as an aluminum block. But it is also conceivable to use a plastic base body or a combination of metal and plastic materials.
- the connecting channel may further be formed as a bore or recess and extend between the two receiving openings, for example, straight through the body. Overall, this makes it possible for the elongate hollow bodies to be arranged reliably and positionally relative to one another and connected to one another.
- the connecting channel is formed at least in sections with a closed cross-sectional profile, for example rectangular or circular. This allows a corresponding secure arrangement and holding the hollow body in the coupling device and can, as explained below, also prevent misalignment of the hollow body to each other. Furthermore, it can be provided that the connecting channel is formed along its entire length, predominantly or at least over a (cumulative) portion of 80% with a closed cross-sectional profile. The closed cross-sectional profile can thus only be interrupted locally,
- the coupling device can furthermore be designed to substantially mold the hollow bodies with fluidic decoupling from the environment to each other.
- the hollow bodies can be enclosed by the coupling device in such a way that they are substantially sealed from the surroundings.
- a pressure medium eg compressed air
- a "substantially fluidic decoupling” is to be understood in particular as a decoupling which, when the hollow bodies are pressurized, enables a pressure loss of less than 20% and, for example, less than 10% or less than 5% via the coupling device.
- the coupling device is designed such that the adapter piece can be arranged therein only under predetermined orientations.

- the coupling device may additionally comprise at least one clamping device, which is designed to clamp at least one of the hollow body and / or the adapter piece in the coupling device.
- Clamping forces can generally allow a centering in the coupling device and / or a desired relative positioning of the hollow body to each other. Likewise, you can fix the hollow body at least temporarily, for example, in a manual replacement and "transposing" the hollow body.
- the clamping device can fix the hollow body and / or the adapter piece permanently in the coupling device, especially during an ongoing operation of the mounting system and below an eventual pressurization of the hollow body with a pressure medium.
- the clamping device can be designed to selectively build up the clamping forces only (for example, after a manual actuation) and otherwise to assume a clamping force-free state.
- the deployable clamping forces may be limited so that they still allow a manual insertion and displacement of the hollow body and / or the adapter piece in the coupling device.
- the clamping forces can generally act radially and, for example, be directed radially inwards, for example with respect to a transverse axis. sectional plane of the receiving openings, on a connecting axis of the coupling device and / or on the longitudinal axes of the hollow body.
- the clamping device can be arranged in the region of one of the receiving openings, that is, for example, in or on one of the receiving openings.
- the clamping device may comprise a nut-threaded arrangement in which a clamping element is received, wherein the clamping element is adapted to generate in accordance with a screwing movement of the nut radial clamping forces.
- the thread may be formed on a base body, which may be generally fixed and / or arranged in a receiving opening or coupled thereto.
- the nut can be movably arranged on the thread, in particular in such a way that it is easily accessible and manually adjustable from outside the coupling device.
- the mother for example, continue to be screwed onto the thread ("screwing" the nut-threaded arrangement), whereby, for example, radially inwardly and thus in the direction of the hollow body and / or Adapter piece directed clamping forces can be generated.
- the clamping element may comprise a flexible deformable material or be made of this and is for example annular. Furthermore, the clamping element may be designed to constrict or widen a receiving region of the clamping device for the hollow body and / or the adapter piece in accordance with the screwing movement. This can be achieved in that the clamping device undergoes an increasing or decreasing compression in this screwing, and thus is urged radially inwardly to varying degrees. According to a variant, the clamping element comprises at least one deformation section, which is increasingly forced out of an initial circumferential plane when the nut is screwed onto the thread and, so to speak, kinks radially inwards.
- the thread may be formed on an outer peripheral surface of a cylindrical or annular base body of the nut-threaded assembly.
- a stop surface can also be provided, on which the clamping element is supported.

- the pressure element may also be formed spherical or roller-shaped and / or rotatably mounted to facilitate the passing past. Further, at least two opposing pressure elements of the aforementioned type may be provided to center the hollow body and / or the adapter piece in the connecting channel.
- At least four pressure elements are provided which can be brought into contact with a respective side of the hollow body and / or the adapter piece.
- at least one corresponding clamping device is provided on both sides of the (axial) center of the connecting channel along its course between the receiving openings.

- the coupling device may further comprise at least one sensor unit, which detects the passage of an element to be conveyed and / or fluid volume through the coupling device and, for example, the passage of a transported through the hollow body metallic component.
- the latter may take the form of a link assume mounting elements for mounting, such as a rivet.
- the sensor unit which can also be referred to as an indicator, can work capacitively or inductively for this purpose, wherein the elements arranged between the sensor unit and the components to be conveyed (hollow body / rivet core, adapter piece) comprise, for example, plastic materials or are produced from these. If such a component transported by the hollow body within the coupling device (eg medium compressed air), the sensor unit can detect this and generate a corresponding signal or a signal pulse.
- the detection range of the sensor unit is arranged in the region of a coupling region of the adapter pieces (eg in the region of the axial center of the connection channel).
- the sensor unit can be assigned to one of the adapter pieces and / or detect, for example, a region which, viewed in the conveying direction, lies between the coupling region of the adapter pieces and an (initial) receiving opening of the coupling device, so that a successful passing of the coupling region can be detected.
- the signal generated by the sensor unit can therefore indicate a successful conveyance of a component by the coupling device and thus at least indirectly confirm a successful coupling of the hollow body. Furthermore, it can be provided that the sensor unit or an associated control unit of the mounting system generates a warning signal if an expected passage of the component is not registered or if a "continuous signal" is present, indicating the sticking of a component in the detection range of the sensor unit.
- the coupling device may further comprise a connection region for the supply of a pressure medium, for example in the form of a compressed air connection, wherein the connection region is fluid-conductively connectable with at least one of the hollow bodies.
- the fluid-conducting connection can be effected via holes through the adapter piece and / or the hollow body.
- the connection region may also be provided as a bore which extends to the connection channel and, for example, extends transversely to a main body longitudinal axis or connection axis.
- the connection region can thus be generally channel-shaped and optionally comprise a thread for connecting a compressed air line.
- the connection region is located in the region of an axial center of the connection channel or near a coupling region of the adapter pieces and / or the hollow body.
- a mounting system comprising the coupling device is designed to continuously or temporarily make a compressed air supply via the connection region in accordance with operating states of the mounting system and / or sensor signals of the sensor unit.
- the time, the duration and / or the volume of the supplied compressed air can be selected in accordance with a detected component passage through the coupling device, a predetermined cycle time and / or a length of the elongated hollow body.
- the coupling device comprises an adapter adapter which can be arranged in the coupling device in such a way that at least one of the hollow bodies can be connected in a flow-conducting manner via the adapter adapter to the connection region.
- the adapter adapter may be arranged adjacent to at least one adapter piece and in particular hereby in plant.
- the adapter adapter between two adapter pieces is arranged, each receiving one of the hollow body, and thereby for example also positioned in the connecting channel of the hollow body.
- the adapter adapter may further comprise a cavity, which is connectable with at least one of the hollow body fluit configuredd to ensure the compressed air supply described above.
- the cavity is channel-shaped and / or formed as a through hole and, for example, has an inner profile that corresponds to that of the hollow body substantially (in particular a T-shaped profile for transporting rivets).
- the adapter adapter may further comprise an annular groove which is fluidly connected to the compressed air connection region and from which, for example, bores extend into the cavity.
- compressed air in the present case may also include suitable gases or gas mixtures and not merely compressed ambient air.
- the disclosure further relates to an assembly, comprising a coupling device according to one of the preceding claims and at least one further exchangeable adapter piece, wherein the adapter pieces are designed to receive hollow bodies with mutually different cross-sectional dimensions.
- the disclosure relates to a mounting system, comprising at least one coupling device according to one of the preceding claims and two elongated hollow bodies, which are connectable to the coupling device, wherein the elongated hollow bodies are formed as supply hoses for mounting elements to a tool unit.
- the hollow bodies are therefore designed to guide components, for example, from a storage unit to a tool unit.
- the storage and / or tool unit can be part of the mounting system or be formed separately from this.
- the mounting elements comprise connecting elements and in particular rivets.
- the hollow bodies may be rivet feed tubes, or so-called rivet cores. These may be generally elongated and formed with a suitable cross-sectional profile (in particular T-shaped) in order to transport the rivets to the tool unit while maintaining a preferred positional orientation.
- the mounting system can also be designed to carry out the supply of the mounting elements to the tool unit under a compressed air loading of the feed hoses.
- the rivet feed hoses may thus be provided that the rivets are moved by compressed air through and along the tubes to get to the tool unit.
- the coupling device allows a fluid-sealing connection of the rivet hoses to be coupled, as explained above.
- the mounting system may further comprise an industrial robot having a plurality of movable robot members, the coupling apparatus being disposed on one of the robot members.
- the industrial robot can be known to be designed as a 6-axis articulated robot, wherein the robot members are connected via the robot axes and movable relative to each other.
- Arranging the coupling device directly on the industrial robot makes it possible to arrange it close to the tool unit as well as a comparatively large distance to any storage unit of the mounting elements. This means that the most wear-resistant intensive and thus often exchanged areas of the hollow body can be formed near the tool unit as a comparatively short hollow body or hose sections, whereby the maintenance and renewal costs can be kept correspondingly low (see also below Erläute ⁇ tion).
- a development provides that the robot members form a kinematic chain, at the end of which a connection region for the tool unit is arranged, and the coupling device is attached to a robot member, which is spaced from the connection region by a maximum of four robot members.
- the coupling device may be attached to a robot member which is spaced from the connection region by a maximum of three, two or only one robot member or to that robot member which is directly upstream of or formed with the connection region.
- this variant provides to arrange the coupling device as close as possible to the tool unit.
- the inventors have recognized that in this area of the industrial robot comparatively large movements can take place in a small space, as a result of which the hollow bodies are correspondingly severely deformed and / or deflected several times. This increases the wear, so that running there hollow body sections must be replaced comparatively early.
- By arranging the coupling device in this area can thus be ensured that a longer first hollow body, which leads for example to a storage unit for the mounting elements, can be used over a longer period.
- a more deformed shorter second hollow body, which leads from the coupling device to the tool unit, however, can be replaced quickly and with little effort after shorter time intervals. As a result, this reduces the cost, since when reaching a wear limit usually only the shorter second hollow body has to be replaced, while the lightly loaded first hollow body can be maintained.

Consequently, the channel inner profile has two different side lengths S1, S2, wherein the side length Sl shown in FIG. 4b slightly exceeds the side length S2.
- the different side lengths S1, S2 correspond to the dimensions of the outer profile of the adapter piece 40 in such a way that the adapter piece 40 can be inserted into the coupling device 12 only under predetermined orientations.
- an adapter piece 40 is selected.
- suitable individual parts 42, 44 are combined with which an adapter profile 40 which is suitably profiled to this cross-sectional profile can be formed.
- the adapter pieces 40 are inserted therein with Nietzuchtschiäuchen 26,28 inserted through each one of the receiving openings 32,34 in the coupling device 12 and moved along the connecting axis V to each other. They are centered by the action of the pressure elements 52 in the respective cross-sectional planes D.
- the adapter pieces 40 In the region of the axial center M of the connecting channel 41, the adapter pieces 40 then collide with their connecting end faces 45, whereby the corresponding end faces of the rivet feed hoses 26,28 are brought into abutment with each other.
- the length X of the adapter pieces 40 is selected such that they extend from the axial center M of the connecting channel 41 to close to the receiving openings 32,34 through the cross-sectional planes D therethrough and are clamped there by the pressure elements 52.
- the above mode of operation, and in particular the clamping and low-loss connection of the rivet feed hoses 26, 28, is further controlled by the parent Thread arrangements 36 in the receiving openings 32,34 improved.
- the nut threaded assemblies 36 each have an annular base body 60, on the outer peripheral surface of a thread 61 is formed.
- a nut 62 is arranged and in response to a screw along the connecting axis V back and forth movable. Both the base body 60 and the nut 62 have on their inner peripheral surfaces on each other axially opposite stop surfaces 64, as indicated schematically in Figure 5 for the nut 60.
- the right receiving opening 34 is shown in Figure 2, which receives the coated rivet feed hose 28 and clamped and sealed by means of the nut thread assembly 36.
- the sheathing of the rivet feed hose 28 is removed at its end, so that the rivet core contained therein and constructed analogously to FIGS. 3a, b can be received directly in an adapter piece 40.
- the left in Figure 2 left nut thread assembly 36 shows that even an uncoated rivet feed hose 28 in the form of a pure Nietseele directly in a nut-threaded assembly 36 is receivable and clamped.
- a sensor unit 70 which is positioned according to FIGS. 2 and 6 in a through-threaded bore 72 in the base body 30 and positioned near the axial center M.
- the sensor unit 70 is designed to detect a passage of the rivets through the adapter pieces 40 and the rivet cores 26, 28, which are accommodated therein and not sheathed in FIG. 6, in the region of the axial center M. In this case, it can generate corresponding sensor signals in order to give an operator (at least indirectly) feedback about a successful coupling and the continuity of the rivet feed hoses 26, 28.
- the sensor unit 70 detects the passage of a metallic rivet through the plastic Fabric manufactured adapter pieces 40 and Nietzuschläuche 26,28 capacitive or inductive and generates a corresponding signal pulse. If a rivet remains stuck in the detection range of the sensor unit 70, the persistent presence of this component is indicated by a corresponding continuous signal, whereupon a control unit of the mounting system, not shown, can output warning signals or adjust the air pressure in the rivet feed hoses 26, 28.
- a control unit of the mounting system not shown, can output warning signals or adjust the air pressure in the rivet feed hoses 26, 28.
- a sensor signal fails at a predetermined time and is generated too late or too early, which is critical for the compliance with predetermined assembly cycle times (see also the following explanation).
- FIG. 6 shows by way of example two sensor units 70 which are inserted in a respective through-threaded bore 72. However, it is also intended to use only one sensor unit 70. For the sake of completeness, it should also be mentioned that FIG. 6 also shows a widened receiving region 74 of the receiving openings 32, 34 in which the nut threaded arrangements 36 (not shown in this illustration) can be received. This is followed by the channel inner profile 54 to avoid the above-explained misalignment of the adapter pieces 40.
- FIG. 7 shows a sectional view in which the
- Cutting plane containing the connection axis V It again recognizes the base body 30, which is designed similarly to FIG. 6, with the elongate connecting channel 41, which accommodates two adapter pieces 40 with rivet feed hoses 26, 28 arranged therein. Furthermore, one recognizes a sensor unit 70 designed similarly to FIG. 6, but in this case it is arranged between the axial center M and the second rivet supply hose 28 (ie viewed in the conveying direction F between the axial center M and the output-side receiving opening 34 or between the coupling region the adapter pieces 40 and the corresponding receiving opening 34). Thus, the sensor unit 70 can still determine whether rivets to be conveyed are reliably transported through the coupling device 12 and, in particular, pass smoothly from one rivet feed hose 26, 28 into the other.
- connection channels 74 formed by transverse bores are instead provided, wherein, in principle, a single such connection channel 74 is also sufficient.
- These channels 74 are connected to a pressure, not shown. air supply device of the mounting system 10 and form connecting portions of the coupling device 12 to continuously or temporarily feed compressed air into the rivet feed hoses 26,28.
- the coupling device 12 comprises an adapter intermediate piece 76, which is arranged along the connecting axis V between the adapter pieces 40 and is in contact therewith.
- the adapter spacer 76 includes a channel-like cavity (not shown) similarly shaped to the T-shaped inner profile of the rivet feed tubes 26, 28 and formed as a through-bore along the connection axis V. Further, the adapter spacer 76 has a similar outer profile as the adapter pieces 40 and is thus also arranged with a predetermined orientation within the connecting channel 41.
- the cavity of the adapter spacer 76 is aligned with the inner profiles of the rivet feed hoses 26,28, so that a rivet can be continuously transported along the connection axis V and from the first rivet feed hose 26 into the cavity of the adapter adapter 76 and from there into the second rivet feed hose 28.
- the adapter spacer 76 further includes an annular groove 78 that orbits around an outer peripheral surface and the connection axis V.
- a plurality of bores 80 extend into the profiled cavity of the adapter spacer 76.
- a single such bore 80 is sufficient.
- four holes 80 are provided, which are distributed uniformly along the annular groove 78.
- compressed air can therefore pass through the channels 74 and the bores 80 into the cavity of the adapter piece 76 and also into the inner profiles of the rivet feed tubes 26, 28 in alignment therewith.
- compressed air can be fed into the second rivet feed hose 28 leading to the tool unit 18 in order to accelerate the rivet transport.
- the mounting system 10 or an unillustrated control unit thereof may generally be designed to activate and / or adjust the compressed air supply via the connection channels 74 continuously or in accordance with specific operating states of the mounting system 10.
- the compressed air supply can be selectively activated when an unreasonably low air pressure level along the transport path of the rivets is detected.
- it can generally be provided to control the compressed air supply in accordance with sensor signals of the sensor unit 70. For example, in the above-described continuous signal due to jamming of a rivet within the coupling device 12, the compressed air supply can be temporarily increased. The same applies if the passage of a rivet is detected by the sensor unit 70 unexpectedly late and the rivet transport is to be accelerated.
- the compressed air supply can be reduced or interrupted if the passage of a rivet is detected unexpectedly early.
- the adjustment of the compressed air supply can be carried out in particular in accordance with a predetermined cycle time and / or rivet delivery time of the mounting system 10.
- a substantially continuous supply of compressed air for example in accordance with a total length of the conveying path of the rivets by the rivet feed hoses 26,28 and the coupling device 12 can be effected by this means that a pressure loss due to stretch or length can be prevented in a preventive manner.
- a similar compressed air supply can alternatively be done without the adapter spacer 76, wherein corresponding annular grooves and / or holes can be provided directly in at least one of the adapter pieces 40.
- the holes can extend through the adapter pieces 40 in the inner profiles of the rivet feed hoses 26,28 or the local Nietseelen inside and allow in the same way a continuous or temporary compressed air supply.
