摘要:
A weft knitting machine having a movable sinker capable of securing a large space at a needle bed near a knitting fabric knitting area and making a pause in the state of stopping action on the knitting fabric knitting area. A sinker operating cam mechanism (10) installed in a carriage acts on the butt (12c) of a sinker jack (12) to move the sinker jack (12) backward from a mouth part (2) so that the acting part (8c) of the movable sinker (8) can retract from the mouth part (2). The sinker jack (12) is locked to a moved back position by a locking mechanism (16). Since a wire (17) passed through a needle plate (5) is utilized to lock the sinker jack (12) in the locking mechanism (16), the locking mechanism (16) can be reduced in size. To lock the sinker jack (12) to the wire (17), the sinker jack (12) comprises a projection (12f).

An object of the invention is to be capable of easily acquiring a fabric having a desired feeling using a stretch yarn. A knitting controller (20) controls a carriage (5), and the like, according to knitting data and control data stored in a memory (21). Data representing relationships between a gauge texture and a stitch loop length being obtained after kitting and the relationships between these gauge texture and stitch loop length and the length and tension of the stretch yarn (2) being fed at the time of knitting are collected previously and stored in the memory (21) in the form of table data. The knitting controller (20) sets control target values of the length and tension of the stretch yarn (2) for a yarn feed controller (23) such that a gauge texture and a stitch loop length being specified by an input unit (22) can be attained, with reference to the table data stored in the memory (21).

Provided is a weft knitting machine having movable sinkers capable of securing a large space at a needle bed near a knitted fabric knitting area and making a pause in the state of stopping action on the knitted fabric knitting area. A sinker operation cam mechanism (10) installed in a carriage acts on the butt (12c) of a sinker jack (12) to move the sinker jack (12) backward from a needle bed gap (2) so that an operation portion (8c) of the movable sinker (8) can retract from the needle bed gap (2). The sinker jack (12) is interlocked at a backward position by an interlock mechanism (16). Since a wire (17) passed through a needle plate (5) is utilized to interlock the sinker jack (12) in the interlock mechanism (16), the interlock mechanism (16) can be reduced in size. To interlock the sinker jack (12) to the wire (17), the sinker jack (12) has a protrusion (12f)

A yarn carrier 1 is capable of being engaged with a pin 4 protruding from a carriage 3 at two engagement points 8, 9 separated by a delay amount ΔL with respect to a center 1a, respectively. Assuming that the carriage 3 approaches from the right with the pin 4 protruding in order to select and haul the yarn carrier 1 stationary on a yarn guide rail 2, the tip of the pin 4 is guided on a guide portion 11b of an oscillating piece 11, and a tip portion 11c prevents engagement with the engagement point 9 by making oscillation displacement about a shaft 11a. The pin 4 is guided to the engagement point 8 by guide portions 13a, 12a of oscillating plates 13, 12, and abuts on a tip portion 10c of an oscillating piece 10, which is engaged with the front side of the pin 4. The oscillating plate 12 also departs from the pin 4, and a tip portion 12c ascends to be engaged with the rear side of the pin 4.

An end yarn inserting device that is so constructed that an end yarn hook can be put into action only when necessary but otherwise be retreated to such a position in the vicinity of a needle bed gap as to avoid interfering with knitting members including a yarn feeder and knitting needles. The end yarn inserting device includes guide rails, an end yarn inserting portion including an end yarn hook, and first and second control portions for controllably moving the end yarn hook to a desired position on the needle bed in the X-axis direction and the Y-axis direction, wherein an end yarn hook having a hook portion for retaining a cross-over yarn thereon and an end yarn hook presser foot having a presser foot portion are superposed on each other and swingably journaled around a journal portion provided on a base sidably supported on the guide rail; wherein the end yarn hook and the end yarn hook presser foot are so arranged as to be swung between their retreated positions and their lowered positions in association with the second control portion; and wherein control means for permitting back and forth swinging motions of the hook portion and the hook presser foot are provided between the end yarn hook and the base.

Needle beds are provided with needles, needle jacks and select jacks and selectors, and the selectors are provided with three butts. The front butt is made to contact the reference plane of the carriage to serve as the fulcrum of rocking. The second butt is used to withdraw the selector, and the tail butt is used to advance the selector. Two pressing cams of the carriage press the tail butt to make the selector to be attracted by a permanent magnet. Two raising cams of the carriage advance the selector to the H position and the A position.

A method determines coordinates of a circumscribed rectangular frame for enclosing each character based on image data of character images in a recognition area. First of all, specified image data of a predetermined data unit in a transverse direction including at least one bit of black pixel are determined by scanning the image data. Thereafter, top and bottom coordinates of a circumscribed rectangular frame are determined respectively by searching respective image data located at the top and bottom positions among plural image data including at least one bit of black pixel located on the upper and lower sides of the specified image data, wherein respective bits of black pixel of plural image data are substantially continuously connected in a longitudinal direction, and then, leftmost and rightmost coordinates of the circumscribed rectangular frame are determined based on histogram data composed of either logical products or logical sums of respective bits in the transverse direction.
