A dispensing system for dispensing a slurry or glaze for making or printing products of the ceramic industry comprises a plurality of reservoirs suitable for containing a respective fluid mixture or glaze and at least one dispenser associated with the reservoirs and equipped with at least one outlet for dispensing the fluid mixture. The system further comprises at least one mixer operatively interposed between the reservoirs and the dispenser, and configured to receive the fluid mixture from each reservoir and to send a mixed fluid to the dispenser, adjusting means operatively interposed between each reservoir and the mixer, and a control unit associated with the adjusting means and configured to drive them so as to adjust the mixing ratio between the flow rates of fluid mixtures into the mixer depending on a reference signal related to a predetermined hue of the mixed fluid.

A method removes a follower plate of a device for transporting viscous material out of a barrel-like container. The device has the follower plate for closing the container, which is open at the top and has a container base and a container casing extending upwards from the base, the follower plate being movable toward and away from the base. A force measuring sensor measures a force exerted by a container onto a placement surface; the controller switches the ventilation mode to the lifting mode if the force exerted by the container onto the placement surface exceeds a first target force value; and the controller switches the lifting mode to the ventilation mode if the force exerted by the container onto the placement surface falls below a second target force value, and/or the at least one sensor measures the position of the container relative to a stationary point.

Technical Problem Provide is a discharge device capable of easily controlling an operation of a plunger at the time of supplying a viscous material to a cylinder and a liquid supply method capable of forming a desired overlap portion.

Solution to Problem The discharge device 10 includes the supply valve 40 which controls the supply of the viscous material M to the cylinder 30, the plunger 50 which applies a pressure to the viscous material supplied to the cylinder, the ball screw 60 which is movable in the same direction as the back-and-forth direction of the plunger, and the motor 120 which is connected to the ball screw through the power transmission mechanism 110, wherein the plunger and the ball screw are not connected.

A device for detecting and replenishing a salt solution in a salt spray machine and the salt spray machine includes a salt solution collector installed at the bottom of the salt spray machine and configured to collect the salt solution, a return pipe is connected to the salt solution collector and the salt solution storage tank, and a pH value sensor, a water level sensor and the salt concentration sensor are connected to the salt solution storage tank.

The present invention relates to a coating apparatus for an elongate workpiece and a method of operating the coating apparatus. The coating apparatus generally includes a first tray and a second tray with coating tubes interconnected to the trays. The coating apparatus is operable to automatically adjust the coating tubes to a predetermined volume of fluid. In one embodiment, the coating apparatus can fill a first coating tube interconnected to the first tray with a first fluid while the elongate workpiece is being dipped into a second fluid within a second coating tube interconnected to the second tray. Optionally, the coating apparatus includes a control system operable to activate a pump to fill the coating tubes with the predetermined volume of fluid. The control system can receive data from a sensor operable to determine a position of an upper surface of the fluid in a tray or a coating tube.

Systems and methods are provided for use with a thermoplastic road marking system (e.g., paint truck). The systems and methods control an insertion or replenishment rate of unmelted thermoplastic paint feed stock into a thermoplastic melter based, at least in part, on the rate that thermoplastic melt is being applied to a marking surface. By substantially matching the replenishment rate into the thermoplastic melter with the application rate, thermal variance within the thermoplastic melter is reduced, which improves the consistency of marking lines applied to surfaces.

Disclosed is a coating device which draws a pattern of a functional liquid on a substrate. The coating device includes: a substrate holding unit which holds the substrate; a droplet discharging unit which discharges a droplet of the functional liquid on the substrate held by the substrate holding unit; a moving unit which relatively moves the substrate holding unit and the droplet discharging unit in a main scanning direction and a sub scanning direction on a base; a mass measuring unit including a cup which receives the droplet discharged by the droplet discharging unit and a mass measuring device which measures a mass of the functional liquid accumulated in the cup; and a liquid drain unit which drains the functional liquid accumulated in the cup.

An application material container has a fixed portion and a container portion. The fixed portion is configured to be fixable to a fixing member included in an application mechanism. The container portion is provided with, in upper and lower portions thereof, a hole and a hole through which an application needle passes. A side surface of the container portion has a first flange. A lower surface of the first flange is in contact with an upper surface of the fixed portion. A gap is provided between a portion lower than the first flange on the side surface of the container portion and a side surface of the fixed portion. The container portion is horizontally movable within a range of the gap.

In solder printer, solder supply device uses positive and negative pressure supply device to apply pressure inside air chamber to move solder cup inside outer tube, such that solder paste is supplied from supply nozzle. Controller, when supply of solder paste from supply nozzle is stopped, performs drive control of positive and negative pressure supply device to decrease the pressure inside air chamber, and uses timer to measure the time required from the starting of decreasing the pressure inside the air chamber to when the pressure inside air chamber has reached a set pressure. Because this required time corresponds to the movement amount of solder cup from the start of supply of the solder paste to when supply is stopped, controller using the measured required to estimate the remaining amount of the solder paste in detail with good accuracy.

System and methods for calibrating a coating system are disclosed. Initially, a material is dispensed using an applicator of the coating system for a predetermined time period. A characteristic of the dispensing of the material for the predetermined time period is then determined. The characteristic of the dispensing of the material is compared to a predetermined range and it is determined that the characteristic of the dispensing of the material is outside of the predetermined range. In response, a velocity of the applicator, a pulse rate of the applicator, a temperature of the material, a pressure of the material supplied to the applicator, or a fan width of the applicator is adjusted to change the characteristic of the dispensing of the material.
