(Solution)
The feeding device (1) of a weft knitting machine provided with a quick-changing sand rocking member (12) extending downward from a base sliding on a running rail and provided with a feed feeding opening (14) A swing arm 2 supported so as to rotate in a forward and backward direction with respect to the rapid sandstones 12 and provided with a feed point 14 at a lower end thereof and a displacement member And a displacement operation means for displacing the attachment feed opening 14 between the reference position and the rear swing position via the swing arm 2 in accordance with sliding of the displacement member 31 in the vertical direction 37).
Description
BACKGROUND OF THE
The yarn feeder of the weft knitting machine has a single yarn feeder arm extending downward from a base sliding on a running rail, and a yarn feeder arm (For example, refer to Patent Document 1). The knitting yarn from the yarn feeder is fed so as to be positioned in the trajectory when the hook advancing from the needle bed to the needle bed gap is retracted, Accepted and yarn caught.
However, depending on the knitting, the knitting yarn from the yarn feeding port is difficult to be fed in the backward trajectory of the hook that has advanced into the needle bed gap.
As one example, in the case of knitting a shape on the way of a knitted fabric, when miss knitting is performed during knit knitting in one knitting course, when shifting from this knitting to knit knitting The knitting yarn from the yarn feeder tends to be delivered at a high position with respect to the trailing trajectory of the hook. In such a case, the knitting yarn easily escapes from the backward trajectory of the hook of the knitting needle that has advanced into the needle bed gap, and there is a possibility that the yarn catching by the knitting needle can not be ensured.
An object of the present invention is to provide a yarn feeding device of a weft knitting machine capable of ensuring yarn catching by a knitting needle.
In order to attain the above object, the present invention is based on the premise that a feeding device of a weft knitting machine provided with a rapid sandstone extending downward from a base supported to slide relative to a running rail, A swing arm which is supported by the swash plate so as to be swung in the forward and backward direction of the needle bed (hereinafter, simply referred to as " forward and backward direction " And a displacement mechanism for displacing the feed port between the reference position as a reference and the forward or rearward swing position via the swing arm at the time of the displacement operation.
The displacement mechanism is provided with a displaceable member which is supported so as to be slidable in the vertical direction with respect to the rapid sandstone, and a sliding member which slides in the vertical direction of the displaceable member, between the reference position and the forward or rearward swing position And the displacement operation means may be provided.
A supporting member provided at the lower end of the displacement member for supporting the vertical middle portion of the swing arm having an upper end attached to the swash arm so as to slide in the vertical direction; An inclined surface portion for guiding the support member to slide in the front-rear direction is provided. And the feed port may be displaced between the reference position and the forward or rearward swing position along the support member guided to slide along the slope portion by the upward and downward sliding of the displacement member.
The swing arm having an upper end attached to the swash plate is inserted into the swing arm, and the swash arm is inserted into the swash arm in the forward and rearward directions And a support pin provided at a lower end of the swash arm for inverting the bending of the swing arm in the forward and backward directions. Further, the swinging of the swing arm in the front-rear direction due to the sliding of the displacement member in the up-down direction is reversed by the support pin so that even if the feed port is displaced between the reference position and the forward or rearward swing position good.
Further, as the feeding opening, an addition feeding feeding opening may be used in addition to the main feeding feeding opening for feeding the injection in the plating knitting.
And an eccentric mechanism having an eccentric member which has an eccentric shaft portion which is rotated about a horizontal axis portion extending in the front and back direction with respect to the swing arm and is eccentric with respect to the horizontal axis portion. The additional feed dog may be located above the main feed dog and may be vertically folded with respect to the main feed dog through the eccentric shaft.
The swing arm swings between the reference position and the swing position forward or backward through the swing arm during operation of displacement of the displacement mechanism relative to the rapid sandstone so that even if the knitting yarn is positioned at a high position, It is easy to insert the knitting yarn from the yarn feeder into the retreating trajectory of the hook, so that the yarn catching by the knitting needle can be ensured.
In addition, the feed port can be displaced between the reference position and the forward or rearward swing position in accordance with sliding of the displacement member in the up-and-down direction with respect to the sudsy sand, so that the feed port can be easily displaced.
Further, the feed port can be reliably displaced by displacing the feed port between the reference position and the forward or rearward swing position along the support member guided to slide along the inclined face portion by sliding the displacement member in the vertical direction.
The swinging of the swing arm in the front-rear direction due to the sliding of the displacement member in the up-and-down direction is reversed by the support pin so that the swinging arm is displaced between the reference position and the forward or rear swing position, Can be displaced.
In addition, by applying it to a feed yarn feeder that feeds a yarn in a plating knitting pattern, it is easy to insert a yarn that has a high position for the yarn in the backward trajectory of the hook of the knitting needle advancing into the needle bed gap, . Also, the pointed yarn caught by the knitting needle is always positioned in the depth direction side of the hook rather than the scanning, so that the reversal of the pointing to the scanning is eliminated, and the color mixture of the knitted fabric can be surely prevented.
Also, by moving the eccentric shaft portion from the transverse slot to the right and left by rotating about the horizontal axis portion of the eccentric member, the connecting plate is moved up and down with respect to the shaft portion in the longitudinal slot, By constituting the eccentric mechanism which slides the plate in the vertical direction with respect to the rapid sandstone, it is possible to smoothly adjust the vertically adjustable feeding and feeding port by rotation of the eccentric member. Accordingly, it is possible to make fine adjustments of the intervals and angles of the scan and the attaching threads fed to the knitting needle, depending on the thickness of the two yarns, the kind of yarn, the knitting conditions, and the like.
