Abstract: A solder supply device provided with a solder cup housing liquid solder that is tubular and open at one end; a nozzle section, for ejecting solder from the solder container, that is inserted into the solder container; a flange section that is provided on an outer circumferential section of the nozzle section and that is engaged inside of the solder cup; and an outer tube that demarcates an air chamber with the bottom surface of the solder cup. Solder is supplied from the tip of the nozzle section by the solder cup and the flange section being relatively moved by supplying air to the air chamber. Solder is supplied from the solder container without using an air cylinder, electromagnetic motor, or the like.

Abstract: A screen printer in which a photoelectric sensor and squeegees are fixed to a slider, when outward movement printing in which solder on a screen is rolled by an outward movement of the right squeegee is completed, the right squeegee is separated from a state of contacting a right end of a solder roll and a squeegee position pl at that time is input, and, subsequently, the slider is returned until the photoelectric sensor detects a left end of the solder roll and a squeegee position p2 at this time is input. An amount (a solder roll width) of solder remaining on the screen is calculated by subtracting a movement amount from the squeegee position p1 to the squeegee position p2 from a distance from the right squeegee to an optical axis position of the photoelectric sensor on the screen.

Abstract: A photoelectric sensor 60 and squeegees 32 and 42 are fixed to a slider, when outward movement printing in which solder on a screen S is rolled by an outward movement of the right squeegee 32 is completed, the right squeegee 32 is separated from a state of contacting a right end R1 of a solder roll and a squeegee position p1 at that time is input, and, subsequently, the slider is returned until the photoelectric sensor 60 detects a left end R2 of the solder roll and a squeegee position p2 at this time is input. An amount (a solder roll width R) of solder remaining on the screen S is calculated by subtracting a movement amount S from the squeegee position p1 to the squeegee position p2 from a distance X from the right squeegee 32 to an optical axis position of the photoelectric sensor 60 on the screen S.

Abstract: An improved screen printing machine is provided. The main body portion and the support table portion of the printer main body are constructed independently of each other, and the main body portion is supported by the support table portion so as to be movable forward. A feed screw is axially immovably and rotatably held by the main body portion so as to be parallel to the front and rear direction, and the feed screw is engaged with the nut provided on the support table portion. An operator rotates the handle attached to the feed screw to move the main body portion forward with respect to the support table portion so that the main body portion is drawn from the support table portion.
