Abstract

Provided is a screw feeding device with which screw clogging can be automatically resolved even when screw clogging has occurred with a partition member.　This screw feeding device 1 comprises: a screw clogging resolution mechanism K1 that comprises a vibration rail 5 that causes a plurality of screws S to be aligned in a normal orientation and to vibrate and causes the screws S to advance in a predetermined direction; a swinging brush 7 that swings over the vibration rail 5, thereby removing abnormally oriented screws S from the vibration rail 5; and a partition member 8 that is provided above the vibration rail 5 and blocks the advancing of abnormally oriented screws S, the screw clogging resolution mechanism K1 resolving the clogging of the abnormally oriented screws S that has occurred between the vibration rail 5 and the partition member 8. The screw clogging resolution mechanism K1 operates so as to cause the clogged screws S and the partition plate 8 to be spaced apart from each other when the swinging brush 7 swings toward the vibration rail 5.

Abstract

By giving proper variation to each stitch, a hand-drawn texture is imparted to a stitching pattern, seams that feel comfortable and warm are produced, and a pattern that does not significantly impair the form of the original pattern is created.　The coordinate data creation device of the present invention comprises a coordinate data storage unit that stores coordinate data of needle drop positions, and a post-addition coordinate data creation unit that creates new coordinate data by adding a respectively unique value to an X coordinate value or a Y coordinate value of coordinate data for each set of coordinate data stored in the coordinate data storage unit. When the distance between the coordinate data of one needle drop position stored in the coordinate data storage unit and the coordinate data of another needle drop position is equal to or less than a predetermined distance, the post-addition coordinate data creation unit causes a respectively unique value to be added to the X coordinate value or Y coordinate value of the coordinate data of one needle drop position to be the same as a respectively unique value to be added to the X coordinate value or Y coordinate value of the coordinate data of the other needle drop position.

Abstract

A needle-threading device (B) for a sewing machine, comprising a needle-threading shaft (10) that is parallel to a vertically moving needle bar (4) and that is capable of vertical motion and rotation, an operation lever (20) that causes the needle-threading shaft (10) to descend and to rotate, a needle-threading tip part (30) that is provided to the lower end of the needle-threading shaft (10) and that has a needle-threading hook (31), and a needle-threading stopper (6) that is provided to the needle bar (4) and that regulates the descent stopping position of the needle-threading shaft (10), wherein: after descending via the actuation of the operation lever (20), the needle-threading tip part (30) rotates at the descent stopping position and inserts the needle-threading hook (31) into an eye of a needle (2) of one needle (1) among a plurality of needles (1) provided to the needle bar (4), the needle-threading tip part (30) comprises a sliding body (40) that moves vertically relative to the needle-threading shaft (10), a positioning body (50) that is slidable with respect to the sliding body (40), and interlocking mechanisms (13, 54) that cause the sliding body (40) to move vertically with respect to the needle-threading shaft (10) in accordance with the sliding of the positioning body (50), and it is possible to thread a plurality of needles (1) having different height positions with threads (T).
