20130269552 | SCREEN PRINTER AND SCREEN PRINTING METHOD - A holding mechanism | 10-17-2013 |
20140203037 | PASTE SUPPLY METHOD - With a substantially intermediate position as a starting point, a syringe is reciprocated in an X-axial direction with a given reciprocation range by a plurality of times, and a stringiness portion that hangs down from a paste discharge port toward a mask plate is cut off in an intermediate portion thereof. The syringe is traveled to the substantially intermediate position, and with this position as a starting point, the syringe is reciprocated with a reciprocation range smaller than the reciprocation range of the paste cutting operation, and a part of the residual paste hanging from the paste shakes off downward. The syringe is traveled in an end direction of a guide member side, the syringe is rotated about an axial line, and translated into a horizontal storage posture. | 07-24-2014 |
20140366754 | PASTE SUPPLY APPARATUS, SCREEN PRINTING MACHINE, PASTE SUPPLY METHOD AND SCREEN PRINTING METHOD - A paste supply apparatus includes a plurality of paste pots each including a bottomed tubular container storing paste and a movable inner lid provided in the tubular container and having a through hole formed in a center portion thereof, and a pot holder which holds the paste pots so as to be horizontally arranged along an arrangement direction such that the through hole of each of the paste pots is directed downward and downward movement of the inner lid thereof is regulated. The paste supply apparatus further includes a pot holder moving device which moves the pot holder along the arrangement direction and selectively positions one of the plurality of paste pots at an ejection position, and a paste ejecting device which presses the tubular container of the paste pot positioned at the ejection position and which ejects the paste in the tubular container from the through hole. | 12-18-2014 |
20140366755 | PASTE SUPPLY APPARATUS, SCREEN PRINTING MACHINE, PASTE SUPPLY METHOD AND SCREEN PRINTING METHOD - A paste supply apparatus includes a plurality of paste pots each including a tubular container which stores paste and which includes a bottom portion provided with a through hole and a movable inner lid provided in the tubular container, and a pot holder which holds the paste pots so as to be horizontally arranged along an arrangement direction such that the through hole of each of the paste pots is directed downward and downward movement of the tubular container thereof is regulated. The paste supply apparatus further includes a pot holder moving device which moves the pot holder along the arrangement direction and selectively positions one of the plurality of paste pots at an ejection position, and a paste ejecting device which presses the inner lid of the paste pot positioned at the ejection position and which ejects the paste in the tubular container from the through hole. | 12-18-2014 |
20140366797 | PASTE SUPPLY APPARATUS AND SCREEN PRINTING MACHINE - A paste supply apparatus includes a paste pot including a tubular container which stores paste and which includes a bottom portion provided with a through hole and a movable inner lid provided in the tubular container, and a pot holder which holds the paste pot in a state in which the through hole of the paste pot is directed downward such that lateral expansion of the tubular container is suppressed and downward movement of the tubular container thereof is regulated. The paste supply apparatus further includes a paste ejecting device which presses the inner lid of the paste pot and which ejects the paste in the tubular container from the through hole. | 12-18-2014 |
20150183209 | PASTE SUPPLY APPARATUS, SCREEN PRINTING MACHINE AND PASTE SUPPLY METHOD - A paste supply method using a paste pot that includes a tubular container which receives paste and is provided with a through hole in a bottom part thereof and an inner lid movable inside the tubular container. The method includes: fixing and holding the paste pot in a posture in which the through hole faces downwardly; ejecting paste from the through hole by downwardly moving a pad member abutted from above on the inner lid of the paste pot held and depressing the inner lid inside the tubular container; and sucking up paste dripping from the through hole inside the tubular container by depressing the inner lid and then upwardly moving the pad member joined to the inner lid and pulling up the inner lid. | 07-02-2015 |
20150258773 | PASTE SUPPLY APPARATUS AND SCREEN PRINTING MACHINE - A paste supply apparatus includes: a pot holder which holds a paste pot including an inner lid movable in a container; an ejecting member; an annular protruding portion protruding downward from a lower surface of the ejecting member; a suction power generating mechanism which generates suction power in an internal space surrounded by the annular protruding portion; and an ejecting member lifting unit which moves up and down the ejecting member, The ejecting member lifting unit causes the ejecting member to press down the inner lid of the paste pot held by the pot holder to eject the paste from the through hole, and thereafter lifts the ejecting member which holds the inner lid by the suction power generated within the internal space of the annular protruding portion by the suction power generating mechanism. | 09-17-2015 |
20150258774 | SCREEN PRINTING MACHINE AND SCREEN PRINTING METHOD - A screen printing machine includes a paste supply apparatus which supplies paste on a mask by using a paste pot including an inner lid movable in a container. The paste supply apparatus includes: a pot holder which holds the paste pot such that a through hole of the container faces downward; an ejecting member which abuts on the inner lid of the paste pot; an ejecting member lifting unit which presses down the ejecting member to eject the paste from the through hole; and a detector which detects a state in which the ejecting member reaches a predetermined press-down limit position in the container. After the detector detects the state in which the ejecting member reaches the press-down limit position in the container, the ejecting member lifting unit continues to press down the ejecting member to further eject the paste. | 09-17-2015 |
20150258775 | PASTE SUPPLY APPARATUS AND SCREEN PRINTING MACHINE - A paste supply apparatus includes: a pot holder which holds a paste pot including an inner lid movable in a container; an ejecting member; an elastic member provided at the ejecting member and including an annular pad portion including a taper having a diameter increasing toward downward; an annular protruding portion protruding downward from a lower surface of the ejecting member within an internal space surrounded by the pad portion; and an ejecting member lifting unit which moves the ejecting member to press down the inner lid to eject the paste. When the ejecting member presses down the inner lid, the pad portion of the elastic member is elastically deformed to extend outside and firmly contacts an upper surface of the inner lid, and the annular protruding portion abuts on the upper surface of the inner lid within the internal space. | 09-17-2015 |
20150258776 | SCREEN PRINTING MACHINE AND SCREEN PRINTING METHOD - A screen printing machine includes: a paste supply apparatus which supplies paste on a mask by using a paste pot including an inner lid movable in a container. The paste supply apparatus includes: a pot holder which holds the paste pot such that a through hole of the container faces downward; an ejecting member which abuts on the inner lid of the paste pot; an ejecting member lifting unit which presses down the ejecting member to eject the paste from the through hole; a detector which detects a position of the ejecting member which is pressed down by the ejecting member lifting unit; and a notification device which generates a notification indicating a remaining amount of the paste in the container based on the position of the ejecting member detected by the detector. | 09-17-2015 |
