Description

Technical Field

[0001] This disclosure relates to the field of tile grouting and grouting products. In particular, it relates to nozzles of grout extruders that can be used for grouting, and more specifically, to nozzles of grout extruders for use in automated grouting robots. Background Technology

[0002] After tiles are installed on a surface, grout is typically applied to fill the gaps between adjacent tiles or between edge tiles and the wall. Grout is a hardening fluid mixture, usually a cement-based mixture, which includes water, cement, and additives (such as sand and polymers) depending on the application. Epoxy and polymer grouts are also used in some applications. Grout is used to increase the mechanical strength of tiles (i.e., to support the edges and keep them spaced apart), to protect the surface beneath the tiles, and to improve the visual appearance of the tiles.

[0003] Applying grout is a laborious process that involves using tools such as trowels or grout paste trowels to push the grout into the gaps between the tiles. Application is done by pushing the grout along the direction of the grout lines across the gaps between the tiles. Any excess grout is then gradually removed from the tiles using a sponge or cloth, taking care not to damage or remove the grout from the gaps between the tiles. Given the manual and labor-intensive nature of this task, various attempts have been made to develop improved tools and equipment, including automated robots.

[0004] However, this is a challenging task because grouting must be done on a wide variety of tiles of different sizes, shapes, and colors laid in various geometric configurations. In particular, the perimeter size and shape of the grout application area vary greatly, and care must be taken when grouting around the edges to avoid grout getting onto the walls or surrounding areas. Furthermore, grouting must be done under various lighting and environmental conditions, such as indoor and outdoor locations.

[0005] Therefore, many tools or devices developed to date are only useful for specific tasks, such as cleaning with a sponge or working in large, open areas far from boundaries. Thus, these tools or devices remain inefficient compared to experienced human grouters / tile installers with trowels and sponges, which are more versatile and capable of grouting a range of different tiles (including into corners and edges) in a variety of locations and environments.

[0006] Grout nozzles for grout extruders are generally known. These nozzles are suitable for applying grout to gaps between floor tiles and to the edges between floor tiles and walls or wall tiles. Grout nozzles typically have grooves that need to be aligned with the gap for proper grout application. However, there is still a need to improve the grouting reliability of automated grouting systems or equipment.

[0007] This disclosure relates, at least in part, to one or more aspects of improving or overcoming existing technical systems. Summary of the Invention

[0008] This disclosure describes a grout nozzle for a grout extruder in an automated grouting robot device as defined in claim 1. The grout nozzle improves grouting reliability by allowing for greater alignment error between the grout application and the gap between the grout and the tile, or between the grout line. The grout nozzle mimics the use of a trowel or grout spatula, allowing for simultaneous application of discharged grout onto the grout line and pushing discharged grout into the grout line. The hydrostatic pressure of the grout is also adjusted during application. The grout nozzle is removable and can be exchanged based on specific needs, such as, but not limited to, the width and depth of the grout line.

[0009] As defined in the appended dependent claims, the sealant nozzle provides a plurality of scrapers that work sequentially to push sealant further into the sealant line. The plurality of scrapers simulate a human hand repeatedly passing through the sealant line. The sealant nozzle also utilizes a guide to redirect residual sealant, allowing it to be applied again to the sealant line. Attached Figure Description

[0062] This disclosure generally relates to a grout nozzle that applies grout discharged from a grout extruder onto a grout line. The grout line is the gap to be filled with grout. An example of a grout line is the gap between tiles. The grout line is located in an application area designated for grouting. The application area includes the grout line and the surfaces of the grout line's flanks. The grout nozzle can be engaged with an automated grouting robot for applying grout to the application area.

[0063] Figure 1 to Figure 6 and Figure 8 to Figure 17(For the purposes of indicating all figures identified by the subletter AF) Various embodiments of the sealant nozzle 10 are shown. The following description discloses general features common to the four embodiments. Each embodiment of the sealant nozzle 10 has a connecting member 12 and a sealant member 14. The sealant member 14 is arranged opposite to the connecting member 12. The connecting member 12 and the sealant member 14 are formed on opposite sides of the sealant nozzle 10.

[0064] In one embodiment, the connecting member 12 and the caulking member 14 are respectively disposed on opposite surfaces of the body of the sealant nozzle 10. The connecting member 12 and the caulking member 14 may be formed as an integral structure. In an alternative embodiment, the connecting member 12 and the caulking member 14 are respectively disposed on a separate body of the sealant nozzle 10. Figure 6 An automated caulking robot device 100 with a caulking extruder 102 is shown.

[0065] Refer to Figure 1 to Figure 6 In one embodiment, the sealant nozzle 10 may extend longitudinally and have a longitudinal axis A. The sealant nozzle 10 may have a first end 11 and a second end 13. The first end 11 and the second end 13 are the lateral ends of the sealant nozzle 10. The longitudinal axis A extends through the first end 11 and the second end 13.

[0066] During operation, the grout nozzle 10 needs to move along the grout line in the grout direction X. The grout nozzle 10 has a defined orientation, wherein a first end 11 precedes a second end 13 relative to the grout direction X. Specifically, when the grout nozzle 10 is aligned in the grout direction X, the first end 11 precedes the second end 13. During operation, the longitudinal axis A can be aligned with the grout direction X. The grout direction X can be substantially parallel to the grout line.

[0067] In one embodiment, the grout nozzle 10 may have an elastomeric coating. Such a coating may be a rubber or rubber-like material. This coating mimics a softer trowel used for grouting and leaves an acceptable finish without damaging the tiles. An example could be a plastic grout nozzle 10 with a rubber coating.

[0068] Refer to Figure 1 to Figure 6 and Figure 8 to Figure 17 The connecting member 12 is configured for connection to a sealant extruder. The connecting member 12 has a connecting device 16 for engaging the sealant extruder and an opening 18 for receiving sealant from the sealant extruder. The connecting device 16 is configured to removably engage the discharge end of the sealant extruder 102.

[0069] In one embodiment, the connecting device 16 is configured for sliding engagement with a corresponding structure in the sealant extruder 102. The sliding device 16 includes an axially extending mating structure that slidably fits into the corresponding structure disposed in the sealant extruder 102. The connecting device 16 may be open at a second end 13 to allow relative sliding engagement between the connecting device 16 and the corresponding structure on the sealant extruder 102. The sealant nozzle 10 engages with the sealant extruder 102 by sliding relative to the sealant extruder 102 against the sealant direction X. The connecting device 16 may be closed at a first end 11 to prevent relative sliding engagement between the connecting device 16 and the corresponding structure of the sealant extruder 102. The sealant nozzle 10 disengages from the sealant extruder 102 by sliding relative to the sealant extruder 102 along the sealant direction X.

[0070] In an alternative embodiment, the coupling device 16 may be configured with a removable mechanical engagement device, such as a snap-fit ​​engagement or a fastening engagement.

[0071] refer to Figure 1F The opening 18 allows sealant extruded from the sealant extruder 102 to be discharged through the sealant nozzle 10. The opening 18 is positioned on a surface facing the sealant extruder 102. The opening 18 may be centrally positioned in the connecting member 12. The opening 18 may be defined by the connecting device 16. The connecting device 16 may surround the opening 18. In another embodiment, the opening 18 may be defined by the connecting device 16. In an alternative embodiment, the opening 18 may be disposed within the connecting device 16. Figure 1F Bottom views of the embodiments shown in Figures 2 to 4 are illustrated. The embodiments in Figures 2 to 4 have the structure with opening 18 as in the first embodiment of Figure 1. Figure 5 Having such Figure 1F The opening 18 is shown. Figure 6 It has multiple openings 18.

[0072] In one embodiment, the sealant is discharged directly into the sealant nozzle 10. The sealant from the sealant extruder 102 is typically discharged into the opening 18 at a pressure substantially the same as the extrusion pressure. In an alternative embodiment, the sealant discharge pressure may differ from the sealant extrusion pressure.

[0073] Refer to Figure 1 to Figure 6 and Figure 8 to Figure 17 The sealant member 14 is configured to apply sealant into gaps in the application area. The sealant member 14 faces the application area and contacts the surface of the application area during sealant application. The sealant member 14 is configured to apply sealant discharged from the sealant extruder 102 to the application area. The sealant discharged into the opening 18 flows through the body of the sealant nozzle 10 to the sealant member 14.

[0074] The caulking member 14 includes a caulking surface 20, a restraining device 22, at least one outlet 26, and at least one scraper 30. The caulking surface 20 is the outer layer of the caulking member 14. In one embodiment, the caulking surface 20 is formed on the side opposite to the surface having the opening 18. The caulking surface 20 may be a portion of the outer surface of the caulking member 14. In one embodiment, the caulking surface 20 may include the entire outer surface of the caulking member 14. The caulking surface 20 faces the application area during operation of the caulking nozzle 10. In one embodiment, the caulking surface 20 may be planar. The caulking surface 14 may be substantially parallel to the surface of the application area. The caulking 10 flowing from the caulking nozzle exits through the caulking surface 20. As the caulking nozzle 10 moves along the caulking direction X, the caulking 10 may flow along the caulking surface 20.

[0075] The limiting device 22 restricts the flow of sealant on the sealant surface 20. By restricting the flow of sealant, the limiting device 22 regulates the hydrostatic pressure of the sealant. The limiting device 22 extends from the sealant surface 20. The limiting device 22 extends substantially vertically relative to the sealant surface 20. In one embodiment, the limiting device 22 may be perpendicular to the sealant surface 20. The limiting device 22 may be rigidly disposed on the sealant surface 20. The limiting device 22 may be integral with the sealant surface 20.

[0076] The limiting device 22 has a free edge 23 that contacts the surface of the application area during operation. The free edge 23 is raised relative to the sealant surface 20. The height of the limiting device 22 determines the magnitude of the elevation of the free edge 23 and the amount of sealant that can be limited. The height of the limiting device 22 is constant, such that the free edge 23 has a consistent elevation throughout the limiting device 22. In one embodiment, the height of the limiting device 22 may vary continuously from a first end 11 to a second end 13 (or vice versa), such that the elevation of the free edge 23 varies accordingly. The free edge 23 may be flat. The free edge 23 may be parallel to the sealant surface 20 and / or the surface of the application area. In alternative embodiments, the free edge 23 may be angled or curved.

[0077] The limiting device 22 defines a sealant flow region 24 on the sealant surface 20. The sealant flow region 24 is defined by the limiting device 22, the sealant surface 22, and a plane formed on the free edge 23. The horizontal axis of the sealant flow region 24 is constrained by the limiting device 22. The limiting device 22 provides a lateral boundary for the sealant flow region 24. The vertical axis of the sealant flow region 24 is constrained by the sealant surface 20. The sealant surface 20 has an upper boundary, and the plane formed by the free edge 23 provides a lower boundary. The sealant flow on the sealant surface 20 and the sealant flow through the sealant region 24 are limited by the limiting device 22 and the combination of the sealant surface 20 and the surface of the application area.

[0078] The application of sealant in the application area is controlled by the amount of sealant, hydrostatic pressure, and flow in the sealant flow area 24. The side of the limiting device 22 that defines the sealant flow area 24 may be substantially perpendicular to the sealant surface 20 to maintain the sealant flow and hydrostatic pressure in the sealant flow area 24.

[0079] Unused sealant can flow away from sealant area 24 through areas not restricted by any limiting device 22. Channels 25 can be formed in areas without limiting devices 22. In one embodiment, multiple channels 25 can be formed in the limiting device 22. In an alternative embodiment, the limiting device 22 can be formed without channels 25. In another embodiment, the limiting device 22 can be formed with channels 25 blocked by scrapers as disclosed below.

[0080] In one embodiment, the limiting device 22 includes a plurality of limiting walls 22. The limiting walls 22 at least partially surround the sealant surface 20. A region on the sealant surface 20 may remain without any limiting walls 22. The limiting walls 22 extend horizontally above the sealant surface 20. The limiting walls 22 extend linearly through the sealant surface 20.

[0081] In one embodiment, the limiting wall 22 includes a pair of sidewalls 40, 42 extending on opposite sides of the sealant surface 20. The pair of sidewalls 40, 42 may be parallel to each other and have the same axial length. The pair of sidewalls 40, 42 may be parallel to the longitudinal axis A. The pair of sidewalls 40, 42 extend linearly from a first end 11 toward a second end 13. The limiting wall 22 may include an end wall 44 that connects the pair of sidewalls 40, 42 at an end of the sealant surface 20. The end wall 44 may be positioned adjacent to or at the first end 11. The end wall 44 may be flush with the first end 11. The end wall 44 is perpendicular to the pair of sidewalls 40, 42. The end wall 44 extends transversely to the longitudinal axis A. The length of the end wall 44 is determined by the mutual distance between the sidewalls 40, 42. The pair of sidewalls 40, 42 may not be connected at the ends opposite to the end wall 44 to form a channel 25.

[0082] In another embodiment, the limiting device 22 includes a single limiting wall 22. The limiting wall 22 at least partially surrounds the sealant surface 20. A region on the sealant surface 20 may remain without any limiting wall 22. The limiting wall 22 is formed by a single wall without corners. The limiting wall 22 extends horizontally above the sealant surface 20. The limiting wall 22 may be curved, arc-shaped, or rounded. The ends of the limiting wall 22 do not contact to form a channel 25.

[0083] In an alternative embodiment, the limiting wall 22 or more limiting walls 22 may be configured to restrict the flow of sealant over the entire sealant surface 20. The limiting wall 22 surrounds the entire sealant surface 20. No channel 25 is formed in the limiting wall 22 or more limiting walls 22 in this embodiment.

[0084] Outlet 26 provides a discharge point for the extruded sealant. The sealant extruded from the sealant extruder 102 passes through opening 18 and through outlet 26 into the sealant flow area 24. Outlet 26 is disposed in the sealant surface 20 and located within the sealant flow area 24. Outlet 26 is formed at the level of the sealant surface 20. Outlet 26 is connected to a through-hole that connects to opening 18. This through-hole can extend through the body of the sealant nozzle 10.

[0085] The outlet 26 can be shaped and sized according to the sealant application requirements of the sealant nozzle 10. In one embodiment, the outlet 26 is rectangular in plan view. The outlet 26 is oriented such that its longitudinal axis is perpendicular to the longitudinal axis A. The sealant is discharged from the outlet 26 at a pressure substantially the same as the extrusion pressure. In an alternative embodiment, the sealant discharge pressure may differ from the sealant extrusion pressure.

[0086] The outlet 26 is located at the end of the sealant surface 20. The outlet 26 is located at the front end of the sealant surface 20 relative to the sealant direction X. The outlet 26 is positioned adjacent to the first end 11. The outlet 26 is positioned adjacent to the restraining device 22. In one embodiment, the outlet 26 is abutted against the restraining device 22. In particular, the outlet 26 is adjacent to the end wall 44. The outlet 26 may be abutted against the end wall 44.

[0087] The outlet 26 is centered relative to the side of the sealant nozzle 10. The outlet 26 is positioned along a longitudinal axis A. In one embodiment, the longitudinal axis A passes through the center of the outlet 26.

[0088] The sealant component 14 may have a first outlet (which is outlet 26) and a second outlet 28. The second outlet 28 provides another discharge point for the extruded sealant. Figure 1F As shown, sealant extruded from sealant extruder 102 into second opening 19 passes through second opening 19 and through second outlet 28 into sealant flow region 24. Second outlet 28 is disposed in sealant surface 20 and located in sealant flow region 24. Second outlet 28 is formed at the level of sealant surface 20. Second outlet 28 is connected to a through-hole that is connected to second opening 19. This through-hole can extend through the body of sealant nozzle 10.

[0089] In another embodiment (not shown), both the first outlet 26 and the second outlet 28 may be connected to the first opening 18. The sealant extruded from the sealant extruder 102 passes through the first opening 18 and through the first outlet 26 and the second outlet 28 into the sealant flow area 24.

[0090] The second opening 19 is axially spaced from the first opening 18. The sealant 102 extruded from the sealant extruder is discharged from both the first opening 18 and the second opening 19. Figure 1F The embodiments shown in Figures 2 to 4 are bottom views. The embodiments in Figures 2 to 4 have the structure with a second opening 19 as in the first embodiment of Figure 1.

[0091] The second outlet 28 can be shaped and sized according to the sealant application requirements of the sealant nozzle 10. In one embodiment, the second outlet 28 is rectangular in plan view. The second outlet 28 is oriented such that its longitudinal axis is parallel to the longitudinal axis A. In one embodiment, the longitudinal axis of the second outlet 28 coincides with the longitudinal axis A.

[0092] The sealant is discharged from the second outlet 28 at a pressure substantially the same as the extrusion pressure. In an alternative embodiment, the sealant discharge pressure may differ from the sealant extrusion pressure. The sealant discharged from the second outlet 28 mixes with residual sealant from the first outlet 26 that was not pushed into the sealant line.

[0093] The second outlet 28 is located at the end of the sealant surface 20. The second outlet 28 is located at the tail end of the sealant surface 20 relative to the sealing direction X. The second outlet 28 is spaced apart from the first end 11 and positioned toward the second end 13. The second outlet 28 may be positioned adjacent to the second end 13. In one embodiment, the second outlet 28 is positioned adjacent to the channel 25 in the restraining device 22. In an alternative embodiment, the second outlet 28 may be located in the channel 25. In another embodiment, the second outlet 28 is positioned adjacent to the restraining device 22.

[0094] The second outlet 28 is centered relative to the side of the sealant nozzle 10. The second outlet 28 is positioned along a longitudinal axis A. In one embodiment, the longitudinal axis A passes through the center of the second outlet 28.

[0095] In the sealant flow area 24, a first outlet 26 and a second outlet 28 are axially spaced apart. The first outlet 26 precedes the second outlet 28 along the sealant direction X. The first outlet 26 is located between the first end 11 and the second outlet 28. The length of the first outlet 26 is longer than the width of the second outlet 28, wherein the length of the first outlet 26 and the width of the second outlet 28 are both oriented perpendicular to the longitudinal axis A. The width of the first outlet 26 is shorter than the length of the second outlet 28, wherein the width of the first outlet 26 and the length of the second outlet 28 are parallel to or coincide with the longitudinal axis A.

[0096] In one embodiment, the sealant member 14 may have a plurality of first outlets 26 and / or second outlets 28. The plurality of first outlets 26 may be arranged linearly along longitudinal axis A between end wall 44 and second outlets 28. The plurality of first outlets 26 may be arranged equidistant from each other along longitudinal axis A. Each first outlet 26 is connected to a corresponding first opening 18. The second outlet 28 is following the first outlet 26 at the end (i.e., closest to the second end 13). In another embodiment, the plurality of second outlets 28 may be linearly located along longitudinal axis A between the first outlet 26 and the second end 13. The plurality of second outlets 28 may be positioned equidistant from each other along longitudinal axis A. Each second outlet 28 is connected to a corresponding second opening 19.

[0097] The grout discharged from the first outlet 26 or more outlets 26 at the rear mixes with the residual grout from the first outlet 26 at the front, which has not been pushed into the grout line, before merging with the second outlet 28 or more outlets 28 at the rear. The grout discharged from the second outlet 28 or more outlets 28 at the rear mixes with the residual grout from the first outlet 26 or more outlets 26 at the front, which has not been pushed into the grout line.

[0098] The scraper 30 is configured to push the discharged sealant into gaps in the application area. During operation, the sealant flowing from the outlet 26 contacts the scraper 30 and is pushed along the sealant line by the scraper 30 into the gaps that need to be filled. The scraper 30 extends from the sealant surface 20 and is located in the sealant flow area 24. The scraper 30 extends substantially vertically relative to the sealant surface 20. In one embodiment, the scraper 30 may extend vertically relative to the sealant surface 20. The scraper 30 may be rigidly disposed on the sealant surface 20. The scraper 30 may be integral with the sealant surface 20.

[0099] The scraper 30 has a free edge 31 that contacts the surface of the application area during operation. The free edge 31 is raised relative to the sealant surface 20. The height of the scraper 30 determines the magnitude of the elevation of the free edge 31. The free edge 31 can be flat. The free edge 31 can be parallel to the sealant surface 20 and / or the surface of the application area. In alternative embodiments, the free edge 31 can be angled or curved. The scraper 30 can extend to the same height as the restraining device 22. The free edge 31 of the scraper 30 can have the same elevation as the free edge 23 of the restraining device 22. In one embodiment, the free edge 31 of the scraper 30 can be flush with the free edge 23 of the restraining device 22.

[0100] The scraper 30 is positioned toward the end of the sealant surface 20. The scraper 30 is positioned relative to the sealing direction X, toward the front end of the sealant surface 20. The scraper 30 is positioned toward the first end 11 and spaced apart from the second end 13. The scraper 30 is positioned adjacent to the first outlet 26.

[0101] The scraper 30 can be centrally positioned relative to the side of the sealant nozzle 10. The scraper 30 can be positioned along a longitudinal axis A. In one embodiment, the longitudinal axis A passes through the center of the scraper 30. The scraper 30 is positioned axially adjacent to the first outlet 26. The first outlet 26 and the scraper 30 are axially aligned. In one embodiment, the first outlet 26 and the scraper 30 are aligned with each other on the longitudinal axis A. The scraper 30 can be centrally positioned relative to the first outlet 26.

[0102] In one embodiment, the scraper 30 has a rectangular base in a plan view. The scraper 30 is oriented such that the longitudinal axis of the rectangular base is perpendicular to the longitudinal axis A.
