Abstract:
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.
Abstract:
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.
Abstract:
A dispensing module and method of dispensing an adhesive includes a dispenser body assembly having a liquid supply passage, a nozzle member having a liquid passageway, a valve element, and a valve seat. The liquid passageway includes a discharge passageway defining an outlet, a first converging surface, a bore, and a shoulder positioned between the first converging surface and the bore. The valve element extends along an axis within the liquid passageway and has a bulbous end portion movable along the axis between an open position and a closed position. The bulbous end portion has a valve needle smaller than the bore to inhibit obstruction to the discharge passageway for adhesive flowing thereto. The valve seat seals against the bulbous end portion in the closed position such that a region of the valve needle projects into the discharge passageway for inhibiting clogging of the adhesive proximate to the outlet.
Abstract:
The present invention relates to a device for dispensing a dispersion, in particular butter, comprising an input means for receiving the dispersion; a pump, for forcing the dispersion under pressure into; a tube, for leading the dispersion under pressure to a delivery unit, comprising a delivery mouth, having an essentially elongate opening; at least one scraper blade, arranged along a first long side of the opening and a collector for moist, arranged under the opening.
Abstract:
A dispensing module and method of dispensing an adhesive includes a dispenser body having a valve element and a nozzle. The nozzle includes a nozzle member, a sealing zone, and a valve seat. The nozzle member includes a liquid passageway having a bore, a cylindrical surface, a second converging surface, and a shoulder. The sealing zone is defined by the cylindrical surface and extends from the bore toward the shoulder and engages the valve element to close a first volume of the liquid passageway from the inlet. The valve seat is defined by the shoulder and the second converging surface and has a circular line of contact that engages the valve element to close a second volume of the liquid passageway from the inlet. The first volume reduces to the second volume as the valve element moves distally along the sealing zone for discharging the adhesive.

Abstract:
The substance of the invention is a method of fluid feeding by means of at least one nozzle (4, 4A, 4B, 4C, 4D, 4E) onto a carrier (2) in a machine of the tobacco industry wherein the fluid is fed to the nozzle (4, 4A, 4B, 4C, 4D, 4E) from a fluid container (10) by means of a feeding device (11), whereas the nozzle (4, 4A, 4B, 4C, 4D, 4E) comprises a body (12, 12A) and at least one movable member (13, 13A, 13C, 13E, 13F, 30), and the fluid is fed onto the carrier (2) through an outlet orifice (15, 15A, 15B, 15C, 15D) of the nozzle (4, 4A, 4B, 4C, 4D, 4E). The nozzle (4, 4A, 4B, 4C, 4D, 4E) comprises also an adjusting mechanism (19, 19A, 19B, 19C, 19D) by means of which the reciprocal position of the movable member (13, 13A, 13C, 13E, 13F, 30) and the body (12, 12A) of the nozzle (4, 4A, 4B, 4C, 4D, 4E) is varied by altering the surface area of the outlet orifice (15, 15A, 15B, 15C, 15D) of the nozzle (4, 4A, 4B, 4C, 4D, 4E). The substance of the invention is a nozzle for fluid feeding onto a carrier (2) in a machine of the tobacco industry, comprising a body (12, 12A) and at least one movable member (13, 13A, 13C, 13E, 13F, 30) and an outlet orifice (15, 15A, 15B, 15C, 15D) for fluid feeding onto the carrier (2).

The application head (15) comprises an injection chamber (10) inside the application head (15) and an injection needle (11) movably mounted inside the injection chamber (10). An opening movement (P) of the injection needle (11) opens an outlet (12). A supply channel (13) and a supply line are also provided in order to introduce the free-flowing medium into the injection chamber (10). A drive (20) generates the opening movement (P) of the injection needle (11). The application head (15) also comprises a lever arm (30), the first end (31) of said arm being movably fixed to a rear end (14) of the injection needle (11) and the second end (32) thereof being connected to the drive.
