Description

TECHNICAL FIELD [0001] The present invention relates to a yarn feeding device for flat knitting machine,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a yarn feeding device for a flat knitting machine and more particularly to a yarn feeding device for yarn catching by a knitting needle when yarn is fed to a knitting needle .

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.

: Japanese Patent Application Laid-Open No. 5-25758

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.

A feeding feed opening 86 is opened at the lower end of the scanning guide hole 851 passing through the forked portion of the main feeding yarn guide 85 in the vertical direction. On the other hand, the feed yarn feeder 19 is open to the lower end of a cusp guide hole 181 passing through the feed yarn guide 18 in the vertical direction. 6, reference numeral 106 denotes an annular groove formed in the eccentric shaft portion 43, and reference numeral 107 denotes a locking mechanism that is engaged with the annular groove 106. [ In Fig. 6, reference numeral 108 denotes a step nut member screwed to the tip end of the shaft portion 441. Fig.

The displacement operation means 63 has a rectangular hole 64 as an insertion hole that opens to the lower end of the displacement member 61. [ A vertical center portion of the swing arm 62 is inserted into the rectangular hole 64 and rearward (downward in FIG. 6) relative to the vertically middle portion of the swing arm 62 with the swash arm 17, And the swing arm 62 is elastically deformed. The displacement operation means 63 includes a pair of left and right support pins 65 at the lower end of the branch piece 84 for supporting the vertically middle portion of the feed yarn guide 18 from the left and right directions. Each of the support pins 65 inverts the bending of the swing arm 62 toward the rear, and rotates the attachment feed opening 19 in the forward and backward directions according to the bending. At this time, when the displacement member 61 slides downward, the rearward bending applied to the swing arm 62 is reduced, and the swing arm 62 is displaced forward by the reduced bending. Each of the support pins (65) reverses the warp of the swing arm (62) displaced forward. 6 (b) and 6 (d)) from the reference position (the position shown in Figs. 6 (a) and 6 (c)) to the rear feed swing position 19 Can be displaced.

6 (a) to 6 (d), the displacement operation to the swing position rearward of the feed yarn feeder 19 by the displacement mechanism 6 is performed by the eccentric mechanism 4 in the vertical direction, ).

6 (a), the screw member 104 is loosened and the shaft portion 611 is disengaged from the shaft portion 611, as shown in Fig. 6 (a) The sliding member 105 slides the displacement member 61 to the highest position. Since the swing arm 62 is provided with a relatively large rearward bending, the swing feed opening 19 at the lower end of the swing feed guide 18 inverted by each of the support pins 65 is moved to the reference position .

6 (b), the screw member 104 is loosened so as to be inserted into the elongated hole 611 (see Fig. 6 The displacement member 61 is slid to the lowest position with respect to the shaft portion 105. [ This reduces the backward warp imparted to the swing arm 62 in the rectangular hole 64 and reduces the warp which causes the swing arm 62 to be displaced in the forward direction, The feed yarn feeder 19 is displaced to the rear swing position. At this time, as shown in Figs. 6 (a) and 6 (b), the eccentric feeding member 19 is rotated by the eccentric member 10 to the one side about the horizontal axis m The swing arm 62 is moved in the vertical slot 621 downward relative to the shaft portion 105 of the screw member 104 so as to be closest to the injection port 86 for injection. In this case, when the screw member 104 is fastened by stopping the displacement member 61 with respect to the shaft portion 105 in the middle of the long hole 611, the attachment feed opening 19 is moved to the arbitrary position between the reference position and the rear swing position As shown in FIG.

6 (c), the screw member 19 is unscrewed as shown in Fig. 6 (c), and the screw member 19 is moved so as to be displaced upward by the eccentric mechanism 10 When the eccentric member 101 is rotated to the other side with the horizontal axis m as the center, the swing arm 62 is operated to move upward in the longitudinal slot 621 with respect to the shaft portion 105 of the screw member 104 And the feed yarn feeder 19 is most distant from the main feed yarn feeder 86.

In the case where the attachment feed opening 19 which is most distant from the main feed feed port 86 by the eccentric mechanism 10 is operated to be displaced to the rear swing position by the displacement mechanism 6, When the screw member 104 is loosened and the displacement member 61 is slid to the lowermost position with respect to the shaft portion 105 in the long hole 611 as shown in Fig. The swinging of the swing arm 62 toward the front side is reversed by each of the support pins 65 so that the swing feed port 19 is moved rearward As shown in FIG.

Next, a third embodiment of the present invention will be described with reference to Figs. 7 and 8. Fig.

7 is a front view of the paper feeder of the flat knitting machine according to the third embodiment of the present invention in the vicinity of the rapid sandstone. Fig. 8 is a cross-sectional view taken along the line CC in Fig. 7. Fig. 8 (a) is a state in which the feed supply port adjacent to the feed water feeding port is displaced to the reference position, (C) is a state in which a feeder feeder is displaced to the reference position, and (d) is a state in which the feeder is displaced to the swing position in the rearward direction, And a state in which the used feed dog is displaced to the rear swing position. In the present embodiment, only the configuration of the displacement mechanism will be described.

7 and 8, the swash plate arm 87 is provided with a swing member 72 which is supported so as to swing in the forward and backward directions through the pin 71 extending in the left and right direction. A substantially quadrangular hole 73 is formed in the lower end of the swing member 72. An eccentric mechanism (9) is provided through a connecting member (75) in the vertical direction of the swing member (72). The swing arm 89 is provided at its lower end with an attached feeding yarn guide 88. The vertical middle portion of the swing arm 89 is inserted so as to slide in the through hole 77 that penetrates the lower edge portion of the hole portion 73 in the up and down direction. The upper end of the swing arm 89 is drawn out to the hole 73 through the through hole 77 and is guided to the lower end of the swing member 72 through a connecting member 75 fixed to the upper end thereof with a screw 76. [ Respectively.

The swing member 72 is provided with a displacement mechanism 8 for displacing the attachment feed opening 93 at the lower end of the swing arm 89 between the reference position and the rear swing position . The displacement mechanism 8 includes a screw hole 81 that is open to the vertical middle portion of the swing member 72 and a tip end of the shaft portion that is screwed to the screw hole 81 toward the surface side of the swing member 72 A nut member 83 which is screwed on the swing member 72 on the shaft portion of the bolt member 82 to fix the bolt member 82 to the swing member 72, And a boss portion 96 which is formed to protrude from the base end of the shaft portion of the bolt member 82 and is fixed so as not to be dislodged by a locking mechanism 95 such as a washer from the backside of the swash plate arm 87. The swing member 72 is supported by the pin 71 against the surface of the swift sandstone 87 in a state where the back surface thereof is slightly raised. When the bolt member 82 is rotated in the counterclockwise direction with respect to the surface side of the swift rocking member 87, the swinging member 72 approaches the surface of the swash rocking member 87 and is inserted into the through hole 77 The swing arm 89 is swung rearward so that the swing feed port 93 is displaced from the reference position to the rear swing position. The lower end portion of the swash rocks 87 is laterally branched and extends downward, and the upper end of a substantially V-shaped main feeding yarn guide 91 is connected to the inner edge of the lower end of each branching yarn 90. And a main feeding opening 92 is opened at the lower end of the scanning guide hole 911 passing through the forked portion of the main feeding yarn guide 91 in the vertical direction. On the other hand, the feed yarn feeder 93 is opened to the lower end of a cusp guide hole 881 passing through the feed yarn guide 88 in the vertical direction. In this case, the reference position and the swing position of the feed yarn feeder 93 are the same as those of the first embodiment.

The connecting member 75 also has a longitudinal slot 751 for receiving and accommodating the shaft portion 902 of the screw member 901 of the screw engagement member 900 of the eccentric mechanism 9 screwed to the swing member 72, And a transverse slot 752 formed at the side of the longitudinal slot 751 for receiving and accommodating an eccentric shaft portion (not shown) of the eccentric member 903.

8 (a) to 8 (d), in addition to the operation of displacing the attachment feed opening 93 rearward by the displacement mechanism 8 to the swing position by the eccentric mechanism 9 in the vertical direction, ).

8 (a), the nut member 83 is loosened, and then the bolt member 82 is rotated in the direction of the reference position The swinging member 72 swings around the pin 71 and is separated from the surface of the swash rock 87 by rotating clockwise with respect to the surface side of the swash rock sand. Thus, the swing arm 89 inserted into the through hole 77 swings forward, and the attachment feed opening 93 at the lower end of the attached feeding yarn guide 88 is displaced to the reference position. At this time, the nut member 83 is fastened to the shaft portion of the bolt member 82 to fix the bolt member 82 to the swing member 72.

8 (b), the nut member 83 is disengaged and the bolt member 82 (see Fig. 8 (b)) is disengaged, The swing member 72 swings about the pin 71 and approaches the surface of the swash rock 87 by rotating the swash plate 72 in the counterclockwise direction with respect to the surface of the swash rock. In this way, the swing arm 89 inserted into the through hole 77 swings rearward, and the attachment feed opening 93 is displaced to the rear swing position. At this time as well, the nut member 83 is fastened and the bolt member 82 is fixed. 8 (a) and 8 (b), the eccentric member 903 is rotated to one side about the horizontal axis m by the eccentric mechanism 9, The connection member 75 closest to the injection port 92 for injection is operated to move downward in the longitudinal slot 751 with respect to the shaft portion 902 of the member 901. In this case, by adjusting the rotation direction and the rotation amount of the bolt member 82 to adjust the amount of contact with the surface of the swash arm 87 of the swing member 72, It is also possible to displace the swing arm 93 to an arbitrary position between the reference position and the rear swing position. 8 (c), the screw member 901 is loosened as shown in Fig. 8 (c). When the screw member 93 is moved so as to be displaced to the reference position by the eccentric mechanism 9, When the eccentric member 903 is rotated to the other side about the horizontal axis m, the connecting member 75 is operated to move upward in the longitudinal slot 751 with respect to the shaft portion 902 of the screw member 901 Most distant from the main feed yarn feeder 92.

On the other hand, when the attachment feed opening 93 which is most distant from the main feed feeding opening 92 by the eccentric mechanism 9 is operated to be displaced from the reference position to the rear swing position by the displacement mechanism 8 8 (d), the swing member 72 is rotated in the counterclockwise direction with respect to the surface of the sliding member 87 by releasing the nut member 83, The swing arm 89 inserted into the through hole 77 is swung rearward so that the attachment feed opening 93 is moved to the rear swing position Is displaced.

In the above embodiments, the displacement mechanisms 3, 6, 8 are applied to the feed feed ports 14, 19, 93. However, the present invention may be applied to feed ports provided singly in the rapid sandstones. In this case, even if the knitting yarn from the yarn feeder is fed at a high position with respect to the backward trajectory of the hook at the time of shifting from the knitting to the knit knitting, the knitting yarn can easily enter the retreating locus of the hook of the needle moving into the needle bed gap So that the yarn catching by the knitting needle can be surely performed.

In addition, in each of the embodiments, in addition to the operation of displacing the addition feeding yarn feeding ports 14, 19, 93 between the reference position by the displacement mechanisms 3, 6, 8 and the swing position at the rear side, 86, and 92 via the eccentric shaft portions 43 and 103 of the first and second feed dogs 4, 10, and 9, Only the displacement operation by the mechanisms 3, 6 and 8 may be performed.

Further, in each of the embodiments, the description has been given of the case in which the feed yarn feeders 14, 19, 93 are displaced between the reference position and the rearward swing position which is farthest to the rear. However, The present invention is also applicable to the case of displacing the swing position between the rearward swing position nearest to the reference position and the swing position from the rearward most swing position. It is needless to say that the present invention can also be applied to a case in which the pointed feed dog is displaced between the reference position and the forward swing position in order to make it easier to insert the pointed tip which is fed from the feed dog feeder into the backward trajectory of the hook. Also, the present invention can be applied to a case in which a feed supply port provided on a sudsy sand different from that of a rapid sandstone provided with a main feed grade sandwheel is displaced between a reference position and a forward or rearward swing position.

Further, in each embodiment, the reference positions are set so that the add-drop feed ports 14, 19, 93 coincide with each other in the back-and-forth direction with respect to the main feed ports 13, 86, Are set arbitrarily. In the case where a primary feeding sand supply and a feeding feed supply are installed in a single rapid sandstreight, if the feeding sandstead and the feeding feedstock are installed in the individual rapid sandstones, The reference position may be set at any position regardless of whether a single feeding opening is provided in the rapid sandstone of the present invention.
