An applicator for delivering a glutinous substance comprises a first body portion, including an end-effector interface, extending from a base portion, a side cover to be removably coupled to the base portion, and a first cavity. A second body portion, having a second cavity intersecting the first cavity, extends from the base portion and is non-parallel to the first body portion. A tip portion, to be removably coupled to the second body portion, comprises a nozzle portion, a third cavity, communicatively coupled with the second cavity, an inner sleeve, having a splined outer surface, and an actuator interface, extending from the second body portion opposite the tip portion. The tip portion and the inner sleeve are interlocked when the inner sleeve is received inside the third cavity of the tip portion, such that the inner sleeve is prevented from rotating with respect to the tip portion.

A coater assembly includes an array of side-by-side selectively closable slot portions to control pressurized fluid flow onto a substrate during relative movement between the coater assembly and the substrate to form a coating pattern on the substrate. A control module produces the coating pattern via control over selective independent closure of the slot portions based on a mapping matrix of individually addressable coatable elements.

An applicator (102) for delivering a glutinous substance (168) to a workpiece (170) from an end-effector (101) is disclosed. The applicator (102) comprises a body (110) and a plunger (186). The plunger (186) comprises a gate (118), movable within an outlet portion (182) of a first channel (115) of the body (110) between, inclusively, an open position, allowing the glutinous substance (168) to flow from an inlet (116) of the first channel (115) to an outlet (117) of the first channel (115) and a closed position, preventing the glutinous substance (168) from flowing from the inlet (116) of the first channel (115) to the outlet (117) of the first channel (115). The applicator (102) further comprises an actuator (131), selectively operable to move the plunger (186) such that the gate (118) moves between, inclusively, the open position and the closed position.

A dispensing unit for controlling flow of a substance is disclosed. The dispensing unit comprises a nozzle and a plug. The nozzle comprises a channel that comprises a first portion and a second portion, communicatively coupled with the first portion. The first portion of the channel has a symmetry axis. The second portion of the channel comprises an outlet that is offset relative to the symmetry axis of the first portion of the channel. The dispensing unit further comprises a plug that comprises a wall and a first aperture, which penetrates the wall through an outer surface of the wall.

A method of removing a glutinous substance from an applicator comprises removing a plunger before the glutinous substance has solidified; allowing the glutinous substance to solidify inside the applicator; detaching a side cover from a base portion of a first body portion to expose a first sealant plug; severing the first sealant plug from a second sealant plug; severing the first sealant plug from a third sealant plug; detaching a tip portion of the applicator from a second body portion to expose a portion of the second sealant plug; extracting the second sealant plug from the second body portion by pulling the portion of the second sealant plug in a direction along the second body portion; separating the first sealant plug from the base portion of the first body portion; and extracting the third sealant plug from an end-effector interface of the first body portion.

The invention relates to an apparatus for applying a viscous material (3), comprising a bell (1) having a circumferential mounting rim (8), and a feed line (2), wherein the material (3) is conveyable via a conveying means through the feed line (2) into the bell (1), wherein the bell (1) can be transported with the mounting rim (8), in a direction of mounting, over a protruding element (9), in particular a rivet head, of a component (9a), in order to encase the element (9) with the material (3), wherein in the region of the bell (1) or the feed line (2) a metering member (1) is provided, wherein in the course of an application process a flow of the material can be influenced by means of the metering member (12).

An applicator (102) for delivering a glutinous substance (168) to a workpiece (170) from an end-effector (101) is disclosed. The applicator (102) comprises a body (110) and a plunger (186). The plunger (186) comprises a gate (118), movable within an outlet portion (182) of a first channel (115) of the body (110) between, inclusively, an open position, allowing the glutinous substance (168) to flow from an inlet (116) of the first channel (115) to an outlet (117) of the first channel (115) and a closed position, preventing the glutinous substance (168) from flowing from the inlet (116) of the first channel (115) to the outlet (117) of the first channel (115). The applicator (102) further comprises an actuator (131), selectively operable to move the plunger (186) such that the gate (118) moves between, inclusively, the open position and the closed position.

A valve type nozzle controls discharge of liquid by opening and closing an discharge port by a valve element, the discharge port being configured to discharge the liquid, and the valve element being formed movably by applying a predetermined voltage to a piezoelectric element, whereby when the predetermined voltage is applied to the piezoelectric element, the valve element moves in a direction where the moving mechanism opens the discharge port when the piezoelectric element extends. This allows the liquid to be discharged. Further, when the application of the voltage to the piezoelectric element is released, the moving mechanism returns to an original shape, by which the valve element closes the discharge port is closed to prevent the discharge of the liquid.

A dispensing unit (100) for controlling flow of a substance (101) comprises a nozzle (102) and a plug (110). The nozzle comprises an outlet (122) and a channel (104) that comprises a longitudinal symmetry axis (130), a sealing surface (106), and an alcove surface (108), contiguous with the sealing surface (106) and outwardly recessed relative to the sealing surface (106); and a plug (110). The plug (110) comprises a wall (112) that comprises an outer surface (114) and that also comprises a first aperture (116), fully penetrating the wall (112) through the outer surface (114) of the wall (112) of the plug (110). The outer surface (114) of the wall (112), comprising the first aperture (116), is complementary with the sealing surface (106) of the channel (104). The plug (110) is movable in the channel (104).

The disclosure concerns an applicator for applying a coating agent (e.g. thick matter) to a component (e.g. motor vehicle body part) with a nozzle with a nozzle opening with a certain nozzle geometry, in particular for applying a thick matter bead to a component surface. The disclosure provides that the nozzle geometry of the nozzle opening can be adjusted without replacing the nozzle, in particular by a relative movement of two nozzle parts. Furthermore, the disclosure comprises an exchange part for such an applicator and an operating method therefor.
