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.

An apparatus for applying a multi-component viscous material to workpieces includes a metering unit having a number of metering valves corresponding to the number of components of the material, as well as a coupling device, and having a mixing unit having a material inlet at a first end, and a coupling part releasably connected to the coupling device, and, at a second end, a mixing tube having an exit opening for the material, as well as a mixing structure arranged in the tube, for mixing the components as they are passed through the tube from the inlet to the exit. A needle valve releases and closes the exit opening and has a valve needle extending in a longitudinal direction from the material inlet to the exit opening that releases the exit opening in a release position, and closes it in a closed position, by contacting a valve seat.

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 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.

A liquid dispensing apparatus (1) includes a liquid contact member (2) that has measuring bores (11, 11). A first piston (3) slides in the first measuring bore (11) and a second piston (3) sliding in the second measuring bore (11). A supply channel (5) communicates with a storage unit (17). An ejection channel (6) communicates with a nozzle (18). A switching valve (4) is disposed in a space in the liquid contact member (2), and that has a first position and a second position. A valve driving mechanism (8) operates the switching valve (4). A piston driving mechanism (9) operates an arm (19) connected to the first and second pistons. The first and second measuring bores are arranged to oppose to each other on both sides of the switching valve (4), and the supply channel (5) and the ejection channel (6) are arranged adjacent to the switching valve.

A nozzle for a food printer including a nozzle head in fluid communication with an edible ink source and arranged to discharge one or more edible inks, wherein the nozzle head includes a plurality of nozzle blade components being movable relative to each other and an opening formed by the plurality of nozzle blade components through which the edible ink is discharged; and a nozzle adjusting mechanism configured to adjust the relative position of the nozzle blade components whereby the dimension of the opening of the nozzle head is adjustable to discharge edible ink with different dimensions so as to print a food material.

The present disclosure pertains to a deposition system, a method and use of such system for filling a groove provided into surface of a workpiece with a printable medium, in particular a highly viscous paste. The system includes a deposition head that includes a first deposition chamber that extends to a first orifice. The orifice is reversibly closed off between at least two shutter elements. In some embodiments the system is a dual chamber system, each chamber having a reversible closable orifice. The system is arranged to maintain a flush physical relationship between the workpiece and the terminal ends of the shutter elements, so as to, upon application of a working pressure, fill the groove.
