Description

[0001] Description

[0002] Fixing aid for components in a spray or spray system and spray or spray applicator for coating workpieces with fixing aid

[0003] Technical area

[0004] The invention relates to a fixing aid for components in a spray or spray system and a spray or spray applicator for coating workpieces with a fixing aid.

[0005] A spray system is used to coat workpieces with coating material. The coating material used is preferably single-component wet paint or multi-component wet paint. To coat a workpiece with wet paint, the wet paint is sprayed onto the workpiece using one or more spray applicators. To improve the adhesion of the paint to the workpiece, the paint can be electrostatically charged. If the paint is a single-component wet paint, the workpiece or paint is then heated. This accelerates the curing process; the thinner escapes from the paint and the paint dries. With multi-component wet paint, heating is generally not required because the curing process is chemically assisted. Once the paint has cured, it forms a continuous and hard top layer on the workpiece.

[0006] A spray system is also used to coat workpieces with coating material. However, the coating material here is a powder. To coat the workpiece, such as a metal pipe, with powder, the powder is sprayed onto the workpiece using one or more spray applicators. To improve the powder's adhesion to the workpiece, the powder can be electrostatically charged. The workpiece or the powdery layer is then heated so that the powdery layer liquefies. After cooling, the formerly powdery layer forms a closed and hard covering layer on the workpiece.

[0007] State of the art

[0008] Spray or splash systems for spraying or splashing material have one or more material hoses through which the material to be sprayed or splashed is transported to the spray nozzle. Such a spray or splash system may also have one or more air hoses.

[0009] A holding arrangement for an electrostatic rotary atomizer is known from the printed document DE 10 2018 108 786 B4. The holding arrangement has a first coupling plate which is intended for connection to a robot and to which a first coupling piece of a fluid coupling and an electrical plug are fastened. The holding arrangement also has a second coupling plate which is designed to be complementary to the first coupling plate. A base plate and the rotary atomizer are fastened to the base plate via a rod. In addition, a second coupling piece of the fluid coupling and a socket are fastened to the second coupling plate. The two coupling plates and thus the plug and socket can be plugged together or spaced apart from one another using two force cylinders. A high-voltage cable which carries the high voltage to the spray nozzle is plugged together in the coupling with the help of the plug and the socket.To ensure that the high-voltage cable does not slip out of the plug, it is screwed tightly to the plug using a cable gland that acts as a strain relief. And to ensure that the high-voltage cable does not slip out of the socket, it is screwed tightly to the socket using another cable gland that acts as a further strain relief. A structure of this type is complex, heavy and prone to errors. In addition, the two coupling plates have a series of media-passing media couplings. A supply line can be connected to each of these media couplings on the upstream side and an outgoing line on the downstream side. However, none of these media couplings has strain relief for these lines. This means there is a risk that the lines will be pulled out of the connections.

[0010] Description of the invention

[0011] An object of the invention is to provide a fixing aid for components in a spraying or injection system in which components can be easily mounted.

[0012] Advantageously, the components are held securely with the fixing aid according to the invention. Any tensile forces that may occur acting on the components are diverted via the fixing aid according to the invention, so that the components can be held free or essentially free from tensile forces. This is particularly relevant for components that are sensitive to mechanical stress. It also has the advantage that no tensile forces act on the component where it is connected. This means, for example, that the material hose on the connection block of the spray applicator can be kept free from tensile forces.

[0013] In addition, the fixing aid according to the invention improves accessibility to the individual components.

[0014] The object is achieved by a fixing aid for components in a spraying or injection system having the features specified in patent claim 1.

[0015] The inventive fixing aid for components in a spraying or injection system comprises a component carrier with component receptacles for receiving the components. Furthermore, the fixing aid comprises a securing element that is movably arranged on the component carrier and designed to close the component receptacles of the component carrier.

[0016] Advantageous further developments of the invention result from the features specified in the dependent patent claims.

[0017] In one embodiment of the inventive fixing aid, the component carrier is disc-shaped. This makes the fixing aid particularly lightweight and space-saving.

[0018] In another embodiment of the fixing aid according to the invention, the component carrier is cylindrical.

[0019] In an additional embodiment of the fixing aid according to the invention, the component carrier has a lateral surface and the component receptacles are open towards the lateral surface.

[0020] In a further embodiment of the fixing aid according to the invention, at least one of the component holders is shaped in such a way that it holds the component to be picked up in a form-fitting manner.

[0021] In a further development of the fixing aid according to the invention, at least one of the component holders is shaped in such a way that it holds the component being picked up in a force-fitting manner.

[0022] In an additional development of the fixing aid according to the invention, the securing element is ring-shaped.

[0023] In another development of the inventive fixing aid, the component carrier has a guide for the securing element. This has the advantage that the securing element does not slip off the component carrier when an axial force acts on the securing element. In a further development of the inventive fixing aid, the securing element and the guide on the component carrier are designed and interact in such a way that the securing element does not slip off the component carrier when an axial force acts on the securing element.

[0024] It is advantageous if the securing element in the fixing aid according to the invention is designed to be elastic.

[0025] It is also advantageous if the fixing aid according to the invention has a clamping device with which the securing element can be fixed to the component carrier. The clamping device can be, for example, a screw, a quick-release fastener, an eccentric, a tension spring, a spring clip, or a bracket.

[0026] In one embodiment of the fixing aid according to the invention, the component carrier is made of plastic or metal. Plastic has the advantage of being electrically insulating. The plastic component carrier is particularly well suited for use in an electrostatic spray or splash applicator.

[0027] Furthermore, the fixing aid according to the invention can be provided with some of the component receptacles having a first cross-section and another part of the component receptacles having a second cross-section that differs from the first cross-section. In a further development of the fixing aid according to the invention, at least four component receptacles are provided.

[0028] Furthermore, a spray applicator for coating workpieces is proposed, which comprises the fixing aid described above and a material hose for coating material and / or an air hose. One of the components to be included is the material hose or the air hose.

[0029] In a further development, the spray or splash applicator according to the invention comprises a cable and / or an optical fiber and / or a high-voltage cascade. One of the components to be picked up is the cable, the optical fiber, or the high-voltage cascade.

[0030] In another embodiment, the spray or splash applicator according to the invention comprises a housing in which the fixing aid is arranged. The housing, in turn, has a stop against which the fixing aid rests. The securing element can rest against the stop in the housing under tension.

[0031] In an additional development, the spray or splash applicator according to the invention comprises a spray head and a rod, by means of which the fixing aid is attached to the spray head. With the aid of the rod, a predefined distance between the spray head and the high-voltage plug can be specified. This advantageously makes it possible to achieve a sufficiently large insulation distance. The rod is advantageously made of an electrically non-conductive material such as plastic. In one embodiment of the spray or splash applicator according to the invention, the component receptacles have the same or smaller cross-sections as the components to be picked up.

[0032] The fixing aid according to the invention is preferably used in a spray or injection applicator, a material conveyor or a control cabinet of a spray system.

[0053] Ways to implement the invention

[0054] Figure 1 shows a first possible embodiment of a

[0055] Spray applicator 1 shown in a three-dimensional view in the open state. The spray applicator 1 comprises a spray head 2, a fixing aid 13, a quick-change coupling 20, a coupling housing 5 and a spray applicator holder 6. Figure 2 shows the spray applicator 1 with spray head 2 and fixing aid 10 in a three-dimensional view obliquely from the front, wherein the coupling housing 5 and the spray applicator holder 6 have been removed. In Figure 3, the coupling housing 5 and the spray applicator holder 6 are shown in a three-dimensional view.

[0056] The spray head 2 of the spray applicator 1 can, for example, be equipped as a rotary spray head with a rotating spray bell 16. Of course, the spray applicator 1 can also be equipped with a differently designed spray head 2. Such a spray head 2 can, for example, have a flat jet nozzle, an angled nozzle, or a round jet nozzle.

[0057] The coupling housing 5 is also referred to below as the housing and is part of the quick-change coupling 20 or the spray applicator 1. In the assembled state, the housing 5 covers the interior of the quick-change coupling 20 and the fixing aid 10 and protects them from external influences. The housing 5 has an upstream opening 5.1 for leading out lines 8. For the sake of clarity, the lines 8 are not shown in Figures 1 to 3. The spray applicator holder 6 is designed such that it can be fastened to the housing 5.

[0058] On the downstream side, the quick-change coupling 20 comprises a connection block 3 which can be fastened to the spray head 2. The connection block 3 can also be part of the spray head 2. It can be connected to the housing 5 by means of a detachable connection. The connection block 3 has line connections 11 to which the lines 8 can be fastened, which lines protrude through the upstream opening 5.1 of the housing 5. The connection block 3 and the housing 5 are designed such that the connection block 3, together with the lines 8, can be at least partially pulled out of the housing 5 on the downstream side 5.7 of the housing 5.

[0059] A high-voltage cascade 12 can also be attached to the terminal block 3. The terminal block 3 can be designed such that it can be at least partially pulled out of the housing 5 together with the high-voltage cascade 12 on the downstream side 5. 7 of the housing 5.

[0060] Furthermore, a strain relief device can be attached to the connection block 3. The strain relief device comprises a spacer 9, which is attached to the connection block 3 on the downstream side and which carries a fixing aid 10 on the upstream side. The spacer 9 is preferably rod-shaped. The connection block 3 can be designed such that it can be at least partially pulled out of the coupling housing 5 together with the strain relief device 10 on the downstream side 5. 7 of the coupling housing 5.

[0061] The lines 8 can, for example, be material lines for conveying powder or paint to the spray head 2. One or more of the lines 8 can also be compressed air lines. If the lines 8 are material lines or compressed air lines, they are preferably designed as hoses.

[0062] On the upstream side of the connection block 3, connections 11 are provided for connecting the lines 8. On the downstream side of the connection block 3, the connections 11 are connected to the spray head 2. To disassemble the lines 8, the spray head 2 is pulled forward, i.e., in a downstream direction, from the coupling housing 5 together with the connection block 3. The coupling housing 5 remains where it is attached, for example, on the spray applicator holder 6 or on the robot.

[0063] One or more of the lines 8 can also be signal lines in order to carry one or more measuring signals from the spray head 2 to a controller (not shown in the figures).

[0064] If the spray applicator 1 is designed, for example, as a rotary atomizer, the spray head 2 can comprise a speed sensor for detecting the speed of the rotating spray bell 16. One of the above-mentioned signal lines can originate from the speed sensor. Such a signal line 18 is shown in Figure 5 and can be fixed using the fixing aid 10.

[0065] The signal line 18 can be a fiber optic cable, for example. The use of a fiber optic cable is particularly advantageous in potentially explosive environments because the measurement signal is transmitted as an optical rather than an electrical signal. This permanently ensures that no ignitable spark occurs in the potentially explosive area.

[0066] Even if a high-voltage cascade 12 is installed in the coupling housing 5, the use of an optical fiber as the signal line 18 is advantageous. The optical fiber can be used to create the insulation distance required for electrical insulation.

[0067] The coupling housing 5 has a first interface 5.3 on its downstream side. The interface 5.3 is provided to connect the coupling housing 5 to the connection block 3. In one possible embodiment, the coupling housing 5 is pushed over the connection block 3 in the area of ​​the interface 5.3, so that the coupling housing 5 is positively connected to the connection block 3. The interface 5.3 can be equipped with one or more bulges or lugs 5.5, and the connection block 3 can be equipped with axial recesses 3.1 and radial recesses 3.2. The lugs 5.5 and the recesses 3.1 and 3.2 form a bayonet lock. When the connection block 3 is inserted into the coupling housing 5 in the correct rotational position, the lugs 5.5 protrude into the axially extending recesses 3.1. The spray head 2 is then rotated together with the connection block 3 relative to the coupling housing 5 around the longitudinal axis LA2 until the lugs 5.5 in the radial recesses 3.2. In this position, the coupling housing 5 and the connection block 3 are firmly connected. To separate the coupling housing 5 and the connection block 3, proceed in the reverse order.

[0068] A second interface 5.4 can be provided on the coupling housing 5, via which the coupling housing 5 is connected to a spray applicator holder 6. The spray applicator holder 6 is provided to hold the spray applicator 1 with a robot, with a lifting device, or in some other way. The spray applicator holder 6 can have a holding rod 7, which is attached, for example, to the robot or the lifting device.

[0069] The second interface 5.4 can be designed as a swivel joint. A knob 6.1 can be provided to fix the position of the spray head 2 relative to the spray applicator holder 6. With its help, the joint position can be fixed or the angle of rotation at the swivel joint can be adjusted.

[0070] The swivel joint can also be designed as a locking swivel joint. Using the locking mechanism, the angle of rotation can be adjusted in steps at defined angles. For example, the swivel joint can be designed to lock in 10° increments. This makes a total of 36 different angles of rotation possible. If required, an angle scale 6.2 can be attached to the spray applicator holder 6. This allows the user to determine the angle of rotation quickly and easily.

[0071] If the bayonet lock between the coupling housing 5 and the connection block 3 is to be released, the spray head 2, together with the connection block 3, is rotated around the longitudinal axis LA2 and then pulled forward in a downstream direction. To ensure that no excessive forces act on the cables 8 and / or the high-voltage cascade 12 and / or the optical fiber 18, these can be attached to the strain relief device 10.

[0072] On the downstream side, the coupling housing 5 can be provided with a bore 5.6 (see Figure 3). The bore 5.6 can, for example, run parallel to the longitudinal axis LA2 of the coupling housing 5 or at an angle to it and can be provided with or without a thread. The coupling housing 5 can be screwed to the connection block 3 using a screw (not shown in the figures). When assembled, the screw projects into the bore 5.6. Instead of or in addition to this, a locking element can also be provided. This also effectively prevents the coupling housing 5 from accidentally rotating relative to the connection block 3.

[0073] The fixing aid 10 comprises a component carrier 13 with component receptacles 13.1 - 13.3 for receiving components 16. In addition, the fixing aid 10 comprises a securing element 4 which is movably arranged on the component carrier 13 and is designed such that it can close the component receptacles 13.1 - 13.3 of the component carrier 13.

[0074] In the following, components 16 are referred to as, for example, the cables 8, the optical fiber 18 and the high-voltage cascade 12.

[0075] A second possible embodiment of a spray applicator 100 with spray head 2 and quick-change coupling 20 is shown in Figures 4 to 7. Figure 4 shows the spray applicator 100 in the assembled state. Figures 5, 6 and 7 show the spray applicator 100 with the coupling housing 15 removed. While the spray applicator 1 has a straight design with a longitudinal axis LA2, which is the longitudinal axis of the spray head 2 and the longitudinal axis of the coupling housing 5, the spray applicator 100 is angled. The longitudinal axis LAI of the coupling housing 15 is oblique to the longitudinal axis LA2 of the spray head 2.

[0076] For the sake of clarity, not all possible lines 8 are shown in Figures 5 and 6; only the high-voltage cascade 12 and the optical fiber 18 are shown. It is also not essential that lines are connected to all connections 11. Some lines 8 are shown as examples in Figure 7. The lines 8 are fluidically connected to the spray head 2 via the connections 11, so that material and / or compressed air and / or another fluid can be guided to the spray head 2 via the lines 8. In addition, two connections 28 at the upstream end of the lines 8 are shown as examples. The lines 8 can be connected to further lines via the connections 28.

[0077] The first interface 15 . 3 on the clutch housing 15 can be identical in construction to the first interface 5 . 3 of the clutch housing 5 .

[0078] The second interface 15.4 of the coupling housing 15 is located in the upstream section of the coupling housing 15. It is preferably located at the upstream end of the coupling housing 15 (see Figures 4 to 7). The second interface 15.4 serves as a spray applicator holder. The spray applicator holder is provided to hold the spray applicator 100 with a robot, a lifting device, or in some other way. For this purpose, the spray applicator holder can have a flange 15.8 with bores, which is screwed or fastened to a correspondingly designed counterpart. The counterpart can, for example, be part of a robot, a lifting device, or a holding arm.

[0079] The functionality of the clutch housing 15 is essentially the same as that of the clutch housing 5. The assembly and disassembly of the clutch housing 15 is also carried out in the same way as for the clutch housing 5.

[0080] Figures 8 to 12 show the first possible embodiment of the strain relief device in various views and in section. The strain relief device comprises the spacer 9, which is attached to the terminal block 3. The spacer 9 can have a thread 9.1 at its downstream end, with which it can be screwed into the terminal block 3. At its upstream end, the spacer 9 is connected to the fixing aid 10. The fixing aid 10 can be attached to the spacer 9 by means of a screw 21.

[0081] The fixing aid 10 can be disc-shaped and have one or more holes 13.1 and 13.2. The size of a hole can be adapted to the cross-section of the cable 8 to be accommodated. For example, the fixing aid 10 can have a large hole 13.1 for a thick cable and a small hole 13.2 for a thin cable. Of course, a plurality of such holes 13.1 and 13.2 can also be provided in order to accommodate a plurality of cables. Furthermore, the fixing aid 10 can have a hole 13.4 for accommodating the high-voltage cascade 12. In addition, the fixing aid 10 can have one or more further holes 13.3. The holes serve as component receptacles.

[0082] It is not mandatory that all component receptacles 13.1 to 13.5 be occupied by components 16. Thus, one or more of the component receptacles 13.1 to 13.5 can be reserved as reserves.

[0083] The fixing aid 10 divides the interior of the housing 5 into an upstream chamber and a downstream chamber. To ensure that air can circulate between the two chambers at all times, one of the holes 13.1 to 13.5 can remain open.

[0084] In addition to the component carrier 13, the fixing aid 10 comprises the fixing ring 4, which at least partially encloses the component carrier 13. The fixing ring 4 can have a slot 4.1. This allows the fixing ring 4 to be slightly widened and pushed over the component carrier 13.

[0085] The component carrier 13 can be provided with a groove 13.8 along its outer surface 13.6, and the fixing ring 4 can be provided with a first circumferential fold 4.3 and / or a second circumferential fold 4.4 along its outer surface. When assembled, the fixing ring 4 lies in the groove 13.8 of the component carrier 13. The two folds 4.3 and 4.4 serve as stops and prevent the fixing ring 4 from accidentally slipping off the component carrier 13.

[0086] A bore 4.2 runs transversely to the slot 4.1 in the fixing ring 4, through which a screw 22 can be screwed in order to clamp the fixing ring 4 onto the component carrier 13.

[0087] For example, to fix a cable 8 in the fixing aid 10, the fixing ring 4 is first loosened slightly by unscrewing the screw 22. The cable 8 is then pushed through a suitable hole 13.1 or 13.2 into the component carrier 13 of the fixing aid 10. If further cables 8 are to be fixed in the fixing aid 10, the further cables 8 can now also be pushed through the suitable holes or component receptacles 13.1 or 13.2. Once you have finished, the screw 22 on the fixing ring 4 can be tightened again so that the fixing ring 4 presses the cables 8 into the holes 13.1 and / or 13.2 with slight pressure and the cables 8 are thus held in position by means of both a positive fit and a friction fit.

[0088] The same applies to the assembly of the high-voltage cascade 12 in the hole or the component holder 13.3.

[0089] Alternatively, a cable 8 can also be clipped through slot 4.1 into hole 13.1 or 13.2. To do this, the fixing ring 4 with the slot 4.1 is rotated to the desired / suitable hole 13.1 or 13.2, and then the cable is clamped or clipped in. The slot 4.1 is then rotated further so that the outer surface of the fixing ring 4 covers the hole 13.1 or 13.2.

[0090] 13.2 closes and prevents the already installed cables 8 from slipping out.

[0091] Advantageously, the fixing aid 10 is supported in the axial direction on the inside of the housing 5. The housing 5 can have a corresponding stop 5.8 for this purpose (see Figure 10).

[0092] It can also be provided that the fixing aid 10 is supported radially on the coupling housing 5. This has the advantage that the cables 8 and / or the high-voltage cascade 12 are not subjected to mechanical stress.

[0093] The holes 13.1, 13.2, and / or 13.4 can be arranged in the component carrier 13 such that they are open toward the outer surface 13.6 of the component carrier 13 (see, for example, Figure 9). The lines 8 can then also be clipped radially into the holes 13.1, 13.2, and / or 13.4 with slight pressure.

[0094] It is also possible to arrange one or more of the holes 13.1, 13.2, and / or 13.4 further inside the component carrier 13. Hole 13.3 can serve as an example.

[0095] Another possible embodiment of the fixing aid 110 is shown in Figures 13 to 15 in various views in the installed state. The fixing aid 110 can, for example, be installed in a wall 25. The wall 25 can be part of a housing. Advantageously, the wall has a web 25.2 to fix the fixing aid 110 in its radial position. The wall 25 has a hole 25.1 through which the cables can be passed, wherein the diameter of the hole 25.1 is advantageously somewhat smaller than the diameter of the strain relief device 110. The wall 25 thus forms an axially acting stop 25.3 for the strain relief device 110. The strain relief device 110 is held in its axial position in the tensile or loading direction by the wall 25. The fixing aid 110 is therefore supported on the stop 25.3 on the wall 25.

[0096] Figures 16 to 18 show various views of a further embodiment of the fixing aid 210 in the uninstalled state. Like the other fixing aids 10 and 110, the fixing aid 210 also comprises a component carrier 33 and a fixing ring 34.

[0097] Here, however, the fixing ring 34 is arranged inside the component carrier 33. In this embodiment, the component carrier 33, like the fixing ring 34, is ring-shaped. The holes 13.1 and / or 13.2 are located on the inside of the component carrier 33. They are closed with the fixing ring 34.

[0098] For example, to fix a cable 8 in the fixing aid 210, the fixing ring 34 is first loosened slightly by unscrewing the screw 35 slightly and loosening the terminal block 36. The cable 8 is then pushed through a suitable hole 13.1 or 13.2 in the component carrier 33. If additional cables 8 are to be fixed, these can now also be pushed through the suitable holes or component receptacles 13.1 or 13.2. The screw 35 on the terminal block 36 is then tightened again so that the fixing ring 34 presses the cables into the holes 13.1 and / or 13.2 with slight pressure, thus holding the cables in their position by means of both a positive fit and a friction fit. If the holes 13.1 and / or 13.2 are shaped accordingly, the cables can also be clicked into the holes.

[0099] The component carrier 33 can have a groove 33.1 on its inner side. Furthermore, the fixing ring 34 can be equipped with a first fold 34.1 and / or a second fold 34.2. When assembled, the fixing ring 34 lies in the groove 33.1 of the component carrier 33. The two folds 34.1 and 34.2 serve as stops and prevent the fixing ring 34 from accidentally slipping out of the component carrier 33.

[0100] In one embodiment, one or more of the component holders 13.1 - 13.5 have the same or smaller cross-sections than the components 16 to be held. The cross-section of the component 16 is reduced by 5 - 20% by the fixing ring 34 when closed. Figure 12a shows the component 16 in the not yet clamped state, and Figure 12b shows it in the clamped state. The components 16 (hoses or lines) can, for example, have a diameter of 4 - 10 mm. If the component 16 has a diameter of 10 mm, for example, its cross-section is partially reduced by 5 - 20% by the fixing ring 34 when closed, i.e. to 8 - 9.5 mm. The cross-section is not narrowed all around by the fixing ring 34, but only on one side. As can be seen in Figure 12b, the component 16 is shown deformed and clamped in the outer area.When the fixing ring 34 is closed, the strain relief is created, whereby the strain relief acts in a force-locking manner. The preceding description of the embodiments according to the present invention serves only for illustrative purposes. Various changes and modifications are possible within the scope of the invention. For example, the various components of the fixing aids 10, 110, 210 shown in Figures 1 to 18 can also be combined with one another in a manner other than that shown in the figures.
