A machine (1) for gluing elements made of various sheets of material such as leather or imitation leather, fabric or cardboard or the like (2), comprises a feeding station (1a) of said elements to be glued (2); a gluing station (1b) of said elements; a conveyor belt (3) adapted to bear a number of said elements (2) along a feed direction (T), a dispenser (4) of glue movable on said conveyor belt (3) and adapted to dispense the glue onto a gluing area (4a) as said elements (2) pass through the gluing station (1b). The machine further comprises at least one alignment device (7) of the elements in leather or imitation leather (2) adapted to identify a positioning area (2a) of the elements in leather or imitation leather (2) on the conveyor belt (3) presenting an extension equal to or greater than the gluing area (4a).

A liquid jet discharge device includes: a narrow tube having a tube shaped body that is open at both ends, and in which a discharge liquid being disposed therein, the discharge liquid contacting at least at an inner face of the narrow tube at a contact angle of less than 90 degrees; a container in which a transmission medium being disposed at a base side thereof where one end of the narrow tube is disposed, so as to enable pressure to be transmitted to the discharge liquid; an adjustment mechanism that causes a liquid surface of the discharge liquid inside the narrow tube and an interface of the transmission medium outside the narrow tube and inside the container to be staggered in position along an axial direction of the narrow tube; and a generation mechanism that generates a pressure wave in the transmission medium such that a liquid jet is discharged from the discharge liquid inside the narrow tube.

The printing apparatus is provided with two inkjet heads that eject ink of the same color as in a first cyan inkjet head (20C1) and a second cyan inkjet head (20C2). The first cyan inkjet head (20C1) and the second cyan inkjet head (20C2) are disposed so that the respective positions in the conveyance direction of the can (10) differ from each other and are disposed so that the positions in the axial direction of the can (10) differ from each other. A first magenta inkjet head (20M1) for ejecting magenta ink is provided at a position adjacent to the second cyan inkjet head (20C2) in the axial direction of the can (10).

A recording apparatus includes a medium setting section on which a recording medium (M) is set; a recording section that records an image on the recording medium set on the medium setting section; and a medium moving section that reciprocates the medium setting section with respect to the recording section. The recording section includes a pretreatment section that supplies a pretreatment liquid to the recording medium when the medium setting section moves in a first direction, a leveling section that is provided on a further downstream side with respect to the pretreatment section in the first direction and levels a recording surface of the recording medium when the medium setting section moves in the first direction, and a supplying section that supplies ink to a leveled recording surface when the medium setting section moves in a second direction.

A discharge device (1) includes a discharge head (10) that discharges a liquid material (50) from a nozzle opening (11) connected to the cavity (14) by varying the internal pressure of a cavity (14) using an actuator (6). The discharge head (10) includes a monitoring portion (12) provided between the cavity (14) and the nozzle opening (11) and the discharge device (1) further includes a detection apparatus (7) that detects the number and/or form of the particle-like bodies (51) included in the liquid material (50) in the monitoring portion (12) of the discharge head (10) and a control unit (74) that drives the actuator (6) according to the detection result (7a) of the detection unit (7) to change the state of the particle-like bodies (51) included in the liquid material (50) of the monitoring portion (12).
摘要:
A defect may occur in which as the amount of fluid discharged by a fluid discharge device decreases, a mask is not filled with the fluid even when the fluid is discharged. In order to fill a workpiece with the fluid, it is necessary to replace air in the workpiece corresponding to a discharge part with the fluid. The air in the workpiece is removed in advance, thereby filling the workpiece with the discharged fluid. A fluid discharge device in which, at one end of a discharge head, a suction port for sucking air in the mask on the workpiece, and a fluid discharge device having a discharge nozzle formed thereon for discharging the fluid are formed is used.

An object of the disclosure is to more appropriately perform high-quality printing in a case of using ultraviolet curing ink in a serial type inkjet printer. As a solution, in a printing apparatus for performing printing in an inkjet mode, an inkjet head (202y) for Y color, an inkjet head (202m) for M color, temporarily hardening light sources (204), an inkjet head (202y), and an inkjet head (202m) are arranged such that their positions in the sub scan direction are deviated from each other. With respect to each position on a medium, after the inkjet head (202y) ejects ink drops, the temporarily hardening light sources (204) hardens the ultraviolet curing ink of the Y color on the medium, to a temporarily hardened state, before the inkjet head (202m) ejects ink drops, and then the inkjet head (202m) ejects ink drops of the M color onto the area where the ultraviolet curing ink of the Y color has hardened to the temporarily hardened state.
摘要:
A dispensing device that dispenses a predetermined volume of fluid into a receptacle has a valve that controls the flow of the fluid through the device. The valve is pre-heated to a calculated operating temperature before dispensing operations begin. Once the temperature of the valve reaches the calculated operating temperature, the device begins dispensing the fluid. The valve is maintained at that calculated temperature during dispensing operations.
