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.

A glue dispensing system and the glue supplying method thereof are disclosed. The glue dispensing system uses at least one feed tank to provide or supply the glue to a glue dispensing needle cylinder. Thus, the glue dispensing needle cylinder does not need to be replaced or the frequency of replacing the glue dispensing needle cylinder can be decreased in order to save more time, reduce manpower waste and decrease the cost.

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.

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.

To restrain a hot-melt adhesive from deteriorating in quality. An apparatus for manufacturing an absorbent article by bonding a material with the hot-melt adhesive, the apparatus including: a melting tank to melt the hot-melt adhesive; a detection sensor detect an amount of the hot-melt adhesive in the melting tank; and a robot move the hot-melt adhesive from a container containing the hot-melt adhesive to the melting tank based on a detection result of the detection sensor.

A pumping apparatus includes a pump chamber, a piston, a motor, and a controller. The controller determines an imaginary terminal point by referring to a dispense command, theoretical information, and a current position of the piston. The controller corrects the imaginary terminal point to a target position by referring to a correction graph. The controller outputs a drive command to the motor for moving the piston from a start position to the target position.

Provided is an application device for applying and spreading an application liquid to and on a predetermined application area of a target surface, which is capable of smearing the application liquid on the application area. The application device (D) includes a brush unit (4) having a brush bristle bundle (41a), and performs a step of causing, while moving a nozzle orifice (32a) of a dispenser (3) along at least a portion of the surface of a rivet (S1) and an area of a wall (Sp) surrounding the base of the rivet (S1), a sealing liquid to be ejected from the nozzle orifice (32a) and to adhere to the portion, and thereafter, a step of spreading the adhering sealing liquid by causing the brush bristle bundle (41a) to slide on the surface of the rivet (S1) and the area of wall (Sp) surrounding the base of the rivet (S1).

Systems and methods related to dispensing fluid and controlling a dispensing operation. The system includes a fluid dispenser including an inlet and an outlet, the dispenser being operable to start and stop the flow of the fluid from the outlet onto a substrate. The system also includes a fluid supply reservoir adapted to hold the fluid, and having an outlet coupled in fluid communication with the inlet of the fluid dispenser to establish a flow path for the fluid between the fluid supply reservoir and the outlet of the fluid dispenser. The fluid supply reservoir further includes a pneumatic input coupled to an air flow path adapted to receive pressurized air for forcing the fluid from the outlet of the reservoir. An electronic air flow meter device is operatively coupled to the air flow path to produce electrical output signals.

An adaptive hot melt feed system includes a melt system, a feed system, a gas control device, a sensor, and a controller. The melt system includes a heated vessel. The feed system is configured to deliver a solid material to the vessel of the melt system for melting. The gas control device is configured to control a supply of gas provided to the feed system to drive the solid material from the feed system to the melt system. The sensor can be configured to detect an amount of material in the vessel of the melt system. The controller is in electronic communication with the gas control device and is programmed to signal the gas control device to vary the supply of gas to the feed system based on a fill metric determined by the controller.
