Description

Technical Field

[0001] This invention particularly relates to an apparatus for applying an applicator to a component (e.g., a vehicle body component, preferably a vehicle chassis), the apparatus comprising at least one cleaning device having a plurality of cleaning openings for dispensing a cleaning fluid. The applicator may be, for example, polyvinyl chloride (PVC, particularly PVC plastisol), a thick material, a coating, an adhesive, a sealant, a preservative (e.g., a wax), and / or an insulating material. The cleaning fluid is preferably air, particularly compressed air. Background Technology

[0002] According to WO2019 / 063425A1, an apparatus for applying an applicator to a component is known. During the application of the applicator, it is possible that the applicator may be applied to specific sections, such as holes, bolts, or threads. To avoid obstruction by the applicator, it is removed from the specific section, thus cleaning the section appropriately. In practice, this is done, for example, by using a manual cleaning gun to perform the necessary cleaning process. Summary of the Invention

[0003] The object of the present invention is to create an alternative and / or improved possibility, particularly for automatically and / or efficiently cleaning partial sections, by means of which an application agent may preferably also be applied.

[0004] This objective can be achieved through the features of the independent claims. Other advantageous embodiments are disclosed in the dependent claims or arise from the following description of preferred exemplary embodiments of the invention.

[0005] The present invention relates to a device for applying an applicator to a component, such as a vehicle body component.

[0006] Application agents may include, for example, polyvinyl chloride (PVC, especially PVC plastisol), thick materials, coatings, adhesives, sealants, preservatives (e.g., waxes) and / or insulating materials.

[0007] The device may include, for example, at least one application opening for dispensing the application agent.

[0008] The device may in particular include at least one cleaning device with a cleaning opening for dispensing cleaning fluid (in particular cleaning air), for example, to facilitate cleaning at least one section, particularly to clean away the application agent.

[0009] The cleaning fluid is preferably distributed via (e.g., pulsed or non-pulsed) output jets. In the context of this invention, the output jets can be, for example, continuous output jets (convenient continuous air) and / or particularly short jets (convenient compressed air jets).

[0010] The cleaning fluid is preferably distributed in a generally laminar flow manner.

[0011] The cleaning fluid is preferably dispensed to the section to be cleaned, such as the section of a component to be cleaned.

[0012] Therefore, the device can be used to apply an application agent on the one hand, and includes at least one cleaning device with a cleaning opening for dispensing cleaning fluid on the other.

[0013] This invention specifically achieves one or more of the following advantages:

[0014] - Compact and / or small devices;

[0015] - Only a very small interference profile;

[0016] - The application and cleaning processes can be performed simultaneously, so they can be done concurrently, for example, in a single work step;

[0017] - Repeatable cleaning and / or application of results;

[0018] - Precise cleaning and / or application of results;

[0019] - Clean sections quickly and / or effectively;

[0020] - Eliminates the need for manual cleaning.

[0021] At least one bulge may be formed between the cleaning openings, preferably to reduce, and preferably prevent, negative pressure during the dispensing of cleaning fluid.

[0022] The bulge is preferably formed centrally between the clean openings.

[0023] The bulge may be, for example, substantially conical and / or conical in shape, preferably substantially conical in shape, for example, with its tip centrally located between the cleaning openings.

[0024] The bulge may, for example, have an inclination angle preferably between 135° and 175°.

[0025] The bulge is preferably exposed.

[0026] Cleaning openings can, for example, be evenly distributed around the ridge.

[0027] The cleaning openings can, for example, be formed into a ring of cleaning openings that are preferably extended in a substantially circular shape, arranged in a substantially uniform distribution (e.g., evenly spaced apart from each other) and / or substantially circularly distributed.

[0028] The cleaning device may have, for example, at least three, at least four, at least five, or at least six cleaning openings.

[0029] The cleaning opening can be conveniently opened from the outlet side to a preferably annularly extended conical output section and / or to a preferably annularly extended, particularly front-side, recess.

[0030] The output section may have a tilt angle, for example, between 5° and 45°, preferably between 10° and 35°.

[0031] The recess is preferably formed by a conical output section and a ridge.

[0032] The cleaning device may include cleaning fluid channels that open into a cleaning opening, such that preferably one cleaning fluid channel can be opened into a cleaning opening respectively.

[0033] The cleaning fluid channel may narrow, preferably tapering, at least in the portion leading to the cleaning opening. This can advantageously increase the flow rate, for example, by at least three times to the flow rate at the cleaning opening. However, the cleaning fluid channel may also form a substantially constant flow cross-section, for example, but optionally including an intake funnel located on the inlet side as described below.

[0034] The cleaning fluid channel can be conveniently extended, at least partially, in an arc shape, preferably without edges (Kanten) along its outline.

[0035] The cleaning fluid channels can be distributed in a substantially circular shape and / or evenly spaced apart from each other.

[0036] The cleaning fluid channel can be connected to a common cleaning fluid distributor on the inlet side, through which cleaning fluid can be distributed into the cleaning fluid channel, preferably in a substantially uniform manner. The cleaning fluid distributor may, for example, include a substantially circular or annular basic structure.

[0037] The cleaning fluid dispenser may include, for example, a pressure tank, preferably in the portion of its interior that is away from the cleaning fluid passage.

[0038] The cleaning fluid dispenser may include, for example, at least one supply through which cleaning fluid can be supplied to the cleaning fluid dispenser, preferably in a substantially centralized and / or decentralized manner (e.g., from the side and / or from the radial outside).

[0039] Clean fluid dispensers may also include, for example, at least two suppliers.

[0040] For example, a supply may enter the cleaning fluid dispenser substantially in a central position, and / or a supply may enter the cleaning fluid dispenser in an eccentric position, particularly from the side and / or radially outside.

[0041] Although the clean fluid supply is dispersed, particularly lateral, in the last third of the outlet side of the clean fluid channel, it can still ensure that the pressure distribution is approximately equal.

[0042] The cleaning fluid channel may have an intake funnel, for example arched and / or inclined, located on the inlet side for intake of cleaning fluid, and the intake funnel may be connected to a cleaning fluid dispenser, for example. The intake funnel may be configured, for example, to allow cleaning fluid to be intake into the cleaning fluid channel in a favorable flow-optimized manner. The side surface of the intake funnel may be, for example, convex.

[0043] The intake funnel is preferably formed so that there are no edges on its outline.

[0044] The cleaning openings and / or cleaning fluid channels may be oriented inward, for example, so that their output jets and / or their central axes are close to each other toward the output side. Alternatively or additionally, the cleaning openings and / or cleaning fluid channels may be oriented such that their output jets and / or their central axes can converge, particularly substantially at the center, preferably crossing and / or bundled. Thus, for example, the core jet downstream of the cleaning opening can be bundled.

[0045] At least one application opening may be formed in the application head and / or at least one cleaning device may be part of at least one cleaning head.

[0046] At least one cleaning head is preferably detachable, for example, it can be attached laterally to the application head on the outside.

[0047] At least one cleaning head may be, for example, slide-in or insertable into the application head, preferably via, for example, a track-shaped guide assembly (e.g., a dovetail guide). Alternatively or additionally, at least one cleaning head may be releasably secured to the application head by a fastening structure (e.g., a screw connection, such as a bolt hole assembly or screw hole assembly).

[0048] Nozzles can be provided.

[0049] An application head and / or at least one cleaning head may be arranged at a particularly distal end of the nozzle.

[0050] The nozzle can be configured, for example, to be mounted on a fully automated machine, particularly a multi-axis robot. The nozzle may include, for example, internal and / or external, at least one conduit for supplying an application agent to at least one application agent opening.

[0051] At least one preferably pneumatically driven spiral feed line (e.g., a double spiral feed line) can be provided through which cleaning fluid can be delivered to at least one cleaning device. The at least one spiral feed line may extend in a spiral shape, particularly around the nozzle, and / or form a spiral hose (e.g., a pneumatic spiral hose), and is preferably tightly attached to the nozzle.

[0052] The spiral feed line preferably does not produce a significant interference profile.

[0053] At least one spiral feed line may be open on the outlet side to, preferably directly or indirectly, at least one cleaning head, particularly to a cleaning fluid distributor.

[0054] Preferably, at least one spiral feed line is provided and / or configured such that the application head and / or at least one cleaning head can preferably rotate positively / negatively at least 360°, preferably without hindering the application process and / or cleaning process.

[0055] The device may include, for example, at least two or at least three application openings, which are preferably oriented in different directions (e.g., 0°, 45° and / or 90° or other suitable orientation angles).

[0056] At least two cleaning devices as disclosed herein can be provided, and therefore at least two cleaning heads as disclosed herein are preferred.

[0057] At least two cleaning devices oriented in different directions can be provided (e.g., 0°, 45° and / or 90° or other suitable orientation angles).

[0058] The shape of the cleaning opening and / or cleaning fluid channel can be, for example, substantially circular and / or strip-shaped.

[0059] The diameter of the cleaning opening can be, for example, less than 4 mm or less than 3 mm.

[0060] The cleaning opening ring, recess, and / or output section can be substantially annular, particularly circular. Alternatively or additionally, the cleaning opening ring, ridge, recess, and / or output section can be arranged, for example, substantially coaxially (e.g., concentrically). In this way, for example, a cleaning device formed coaxially (e.g., concentrically) can be produced.

[0061] The sections to be cleaned may include, for example, preferably threaded holes (e.g., through holes or blind holes) and / or preferably threaded bolts.

[0062] It should be mentioned that at least one cleaning device can be specifically used to clean specific sections of a vehicle chassis, such as holes (e.g., 5 mm in size) and / or threaded bolts (e.g., 15 mm in length), and specifically to remove the applied agent. Cleaning can be performed during and / or after the application of the applied agent (e.g., PVC).

[0063] It should also be mentioned that at least one cleaning device can be used, for example, to remove the application agent dispensed through at least one application agent opening. The section that needs cleaning can be, for example, a section of a component or a section of another component.

[0064] It should also be mentioned again that the cleaning fluid is preferably clean air.

[0065] Cleaning fluid can be applied, for example, to one component or another.

[0066] At least one cleaning device, particularly a cleaning fluid, can be conveniently used to clean the component or another component. The application agent to be removed may be, for example, an application agent already dispensed from at least one application agent opening disclosed herein and / or, for example, an application agent already dispensed from another separate application device.

[0067] The device may include, for example, a mounting structure for mounting on fully automated machines, particularly multi-axis robots, such as articulated arm robots. However, it may also include, for example, a handle for manual use.

[0068] The activation and deactivation of the cleaning fluid distribution can be, for example, freely programmable and / or fully automated, preferably achieved through the motion program of a robot carrying the device. However, alternatively, at least one cleaning device can also be used manually as a hand applicator.

[0069] The present invention also relates to the cleaning apparatus disclosed herein, and in particular to a cleaning head having the cleaning apparatus disclosed herein.

[0070] Therefore, the present invention also claims independent protection for the subject matter and features of the cleaning apparatus disclosed herein.

[0071] The present invention also relates to a method of operating an apparatus for applying an applicator to a component, preferably a method of operating an apparatus as disclosed herein. In this method of operation, the applicator is dispensed from at least one applicator opening, wherein at least one cleaning device includes a cleaning opening from which cleaning fluid is dispensed, particularly for cleaning a section to be cleaned.

[0072] Therefore, the present invention specifically requires independent protection of the subject matter and features of the apparatus, cleaning apparatus, and operating method.

[0073] The cleaning fluid may be dispensed, for example, after the application agent. Alternatively or additionally, the cleaning fluid and the application agent may be dispensed, for example, simultaneously.

[0074] At least one cleaning device can be conveniently positioned before the section to be cleaned, preferably substantially coaxially, for example, by orienting the raised section and / or cleaning opening ring substantially coaxially with the section to be cleaned. This section is preferably a portion of a component.

[0075] The cleaning fluid used to substantially completely clean the section to be cleaned may be dispensed for a maximum of 3 seconds, 2 seconds, 1.5 seconds, or 1 second, for example, in the form of a short compressed air stream. Preferably, at least one cleaning device is then removed directly from the section to be cleaned.

[0076] The cleaning fluid can be dispensed, for example, while at least one cleaning device remains stationary, thus keeping it static, particularly relative to the section to be cleaned. Alternatively or additionally, the section to be cleaned can be cleaned substantially completely, for example, in its circumferential direction and / or its axial direction, preferably without any rotational movement of at least one cleaning device relative to the section to be cleaned.

[0077] The cleaning fluid, in particular, can remove the application agent dispensed through at least one application agent opening from the section to be cleaned. Attached Figure Description

[0087] The preferred exemplary embodiments of the present invention described with reference to the figures partially overlap, wherein similar or identical parts are indicated by the same reference numerals. In order to avoid repetition, reference may also be made to the description of other exemplary embodiments.

[0088] Figure 1 A perspective view of a device 100 according to an exemplary embodiment of the present invention is shown, wherein, Figure 2 It shows Figure 1 Enlarged detailed view. Figure 3 It shows Figure 1 and Figure 2 A perspective view of the cleaning device 10, wherein, Figure 4 It shows Figures 1 to 3 A cross-sectional view of the cleaning device 10.

[0089] The device 100 is used to apply an applicator, particularly a thick material and / or sealant, such as polyvinyl chloride (PVC), to a component 30, such as a motor vehicle body component. The device 100 preferably includes three applicator openings 1, oriented in different directions (e.g., 0°, 45°, and 90°), for dispensing the applicator, although... Figure 1 Only two application openings 1 are visible. Application opening 1 is part of the application head AH.

[0090] The apparatus 100 also includes preferably two cleaning devices 10, each formed as part of two cleaning heads CH. The cleaning heads CH and the cleaning devices 10 are preferably detachably connected to different sides of the application head AH. The two cleaning devices 10 are preferably arranged in different directions. However, apart from the different orientations, the cleaning devices 10 and the cleaning heads CH can have substantially the same structure; therefore, only one cleaning device 10 and its associated cleaning head CH will be described below.

[0091] Cleaning is specifically understood as removing and / or moving applicators that are located on and / or around the section 31 to be cleaned, that may interfere with the function of the section 31, or that should not normally be located there. The applicator to be removed may be, for example, an applicator that has been dispensed from an applicator opening 1, or an applicator that has been dispensed from another separate applicator.

[0092] The cleaning device 10 preferably includes six cleaning openings 11 for dispensing cleaning fluid, preferably for dispensing cleaning air. The cleaning fluid can be... Figure 4 The output jet S, schematically shown, can be distributed in various forms, including continuous, pulsed, long, short, and / or explosive. The cleaning openings 11 are circularly distributed, forming, in particular, annular cleaning opening rings.

[0093] Six cleaning fluid channels 12 are provided, opening into the cleaning opening 11, so that one cleaning fluid channel 12 can be correspondingly opened into one of the cleaning openings 11 (e.g., Figure 11 and 12 The cleaning fluid channel 12 is formed in an arc shape, and preferably tapers towards the cleaning opening 11.

[0094] Preferably, at least one, particularly conical and / or conical, ridge 13 is centrally formed between the cleaning openings 11, which preferably prevents negative pressure from forming during the distribution of cleaning fluid, and in particular keeps the pressure level in the area of ​​the cleaning openings 11 substantially uniform. This advantageously prevents accidental contamination between the cleaning openings 11. It should be noted that, in Figures 1 to 3 The cone-shaped and / or conical ridge 13 cannot be directly seen in the perspective view because it lacks an outline. The clean openings 11 are arranged in a ring around the ridge 13.

[0095] The outlet side of the cleaning opening 11 opens into the annularly extending conical output section 14, particularly into the front recess, which can be defined on the one hand by the output section 14 and on the other hand by the ridge 13.

[0096] The cleaning opening ring, the ridge 13, the recess and the output section 14 are preferably arranged coaxially so as to form a cleaning device 10, which is particularly coaxial.

[0097] On the inlet side, the cleaning fluid channel 12 is connected to a common cleaning fluid distributor 15, through which cleaning fluid can be distributed into the cleaning fluid channel 12, preferably in a substantially uniform manner.

[0098] The cleaning openings 11 and / or cleaning fluid channels 12 are oriented inward so that their central axes and thus their output jets S are close to each other toward the output side A, for example so that the output jets can substantially converge at the center, preferably cross and / or bundle.

[0099] The cleaning head CH is preferably slidable into or inserted into the application head AH via a track-shaped guide assembly (e.g., a dovetail guide) 16 and detachably secured to the application head AH via a fastening structure (e.g., a screw connection) 17.

[0100] The cleaning head CH with cleaning device 10 is arranged laterally on the outside of the application head AH, so that the cleaning head CH and the application head AH do not interfere with each other during their operation.

[0101] Figure 4 It also shows why and how to advantageously clean section 31 using the cleaning device 10.

[0102] One or more application openings 1 are initially used to apply the application agent as required. Figure 4 Component 30 is shown only schematically. However, it is possible that the agent may also reach part of section 31, thus hindering the function of section 31. This part of section 31 may be, for example, a threaded circular bolt.

[0103] The cleaning device 10 can be used to remove and / or process the application agent from the section 31, thereby conveniently cleaning the section 31.

[0104] For this purpose, the cleaning device 10 can initially be positioned axially spaced, particularly coaxially before the section 31, such that the bulge 13 and / or the cleaning opening ring are substantially coaxially oriented with the section 31. In this way, the cleaning fluid can be distributed, preferably by the stationary, static cleaning device 10.

[0105] Figure 4 As shown, the cleaning section 31 can be substantially completely cleaned in its circumferential direction, preferably in its axial direction, by an annular cleaning opening ring formed by the cleaning opening 11, without the cleaning device 10 needing to perform rotational motion relative to the portion of the section 31 for cleaning. Depending on the boundary conditions, the cleaning fluid can be dispensed, for example, after the application of the agent, or simultaneously with the application of the agent.

[0106] The central bulge 13 at the center of the cleaning opening 11 specifically prevents negative pressure from forming at the center of the outflowing output jet S. Therefore, no medium is drawn into the center, and the section 31 is cleaned at its tip. If the conical and / or conical bulge 13 is omitted, the section 31 will not be cleaned at its tip because negative pressure will soon form downstream of the cleaning opening 11, thus drawing the cleaning fluid into the center.

[0107] The cleaning device 10 can, in particular, thoroughly clean round threaded bolts from tip to tip, preferably using only one working step. The threads of the bolt can also be cleaned internally along the threaded sides. For this purpose, the cleaning device 10 does not need to be moved. The cleaning device 10 can be positioned very close to the threaded bolt and injected with a cleaning fluid, particularly compressed air, for a short period, for example, about 0.5 to 1 second. The additional cleaning effect on components 30, such as the surface where the threaded bolt is mounted, is another advantage achievable by the cleaning device 10.

[0108] Figures 5 to 10 Different views of a device 100 according to an exemplary embodiment of the present invention are shown.

[0109] A nozzle 22 is provided, with an application head AH and at least one cleaning head CH arranged at its particularly distal end. The device 100 also includes at least one helical feed line 21, which extends spirally around the nozzle 22 on the outside. Through the helical feed line 21, cleaning fluid can be delivered into the cleaning device 10, in particular without requiring a large amount of interference profile for this purpose.

[0110] The spiral feed line 21 can be conveniently opened, either indirectly or directly, to, for example, a cleaning fluid distributor 15.

[0111] The device 100 may also preferably include a mounting structure through which the nozzle 22 can be mounted onto a multi-axis robot, preferably an articulated arm robot.

[0112] Figure 11 and 12 Different views are shown, particularly different views of the cleaning fluid passage 12 that opens into the cleaning opening 11. A cleaning fluid passage 12 can be correspondingly opened into a cleaning opening 11.

[0113] The cleaning fluid channel 12 is connected at its inlet side to a common, preferably circular or annular, cleaning fluid distributor 15, through which cleaning fluid can be distributed into the cleaning fluid channel 12. The cleaning fluid distributor 15 preferably includes at least two suppliers 19 and 20 through which cleaning fluid can be delivered. Supplier 19 forms a central supply, and supplier 20 forms a distributed supply.

[0114] The cleaning fluid channel 12 includes, on the inlet side, a preferably arched intake funnel 18 for the inflow of cleaning fluid, wherein the intake funnel 18 can be easily connected to the cleaning fluid dispenser 15.

[0115] The optional cleaning fluid distributor 15 can be configured to provide, for example, the desired volumetric flow rate of cleaning fluid (e.g., air), preferably with low pressure loss to at least one supplier 19 and / or 20, and to distribute the cleaning fluid mass evenly to the respective cleaning fluid channels 12.

[0116] Figure 13 A cross-sectional view of a cleaning head CH having a cleaning device 10 is shown according to an exemplary embodiment of the present invention.

[0117] Figure 13 In particular, a ridge 13 formed in a conical and / or conical shape is shown, with an inclination angle A1, for example, between 135° and 175°, particularly about 155°.

[0118] Figure 13 Specifically shown is the output section 14 formed in a conical and / or conical shape, with an inclination angle A2 of, for example, 10° to 35°, particularly about 22°.

[0119] 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 its scope of protection. In particular, this invention claims independent protection for the subject matter and features of the apparatus, cleaning device, and method of operation.
