Description

Horizontal volume machine

Technical field

The present invention relates to the horizontal volume machine of four needle-bars etc., the front side needle-bar of configuration and at least one side in the rear side needle-bar horizontal volume machine across the tooth mouth and in opposite directions with two-layer needle-bar.

Background technology

In the prior art,, make a plurality of knitting needles of being set up in parallel on needle-bar braid movement, form coil arc making knit fabric while draw in the stocking yarn of giving by the tooth confession with respect to tooth mouth advance and retreat for horizontal volume machine.Be formed with parallel needle tray on needle-bar, the braid movement of knitting needle is guided by needle tray.Knitting needle in needle tray on the direction of relative tooth mouth advance and retreat slide displacement, for the direction of this direction quadrature side support by needle tray.Yet, the end side of knitting needle since braid movement hang with stocking yarn midway, so expose from needle tray.In order to make knitting needle not become obstacle when drawing in stocking yarn, the end side that faces the tooth mouth in needle-bar requires to expand frontal width, thereby needle tray can't be formed up to end side.Therefore, before the knitting needle that is used to form the coil arc makes end, go out to the state of tooth mouth, do not bear the part towards the supporting of side of being undertaken and expose more by needle tray.

Known have such prior art,, for the end side part at the needle-bar of having expanded frontal width supports the side of knitting needle, and is provided with projection (for example with reference to the real public clear 42-6263 communique of Japan) that is.In the prior art,, in a side that is equivalent to the width inboard projection is set with the frontal width of needle tray from the central portion left and right symmetrically of needle-bar at the knitting needle that pulls the both end sides of knitting width because of grey cloth respectively to the inside, thus the bending of restriction knitting needle.

In addition, also known such prior art promptly, is provided for holding the guide groove (for example with reference to Japanese kokai publication hei 9-49153 communique) of knitting needle bottom in the least significant end side of needle-bar.In the prior art, in the horizontal volume machine of tooth mouth two-layer needle-bar in opposite directions, on each knitting needle, be provided with diving board at the front and back needle-bar in a side.Sky is opened compartment of terrain configuration sinker between the knitting needle of each needle-bar, receives and supports for being applied to horizontal load on the knitting needle by stocking yarn in weaving operation, utilizing the guide groove that forms the degree of depth that does not contact with the diving board bottom to knitting needle.The setting of guide groove is to be used for, and prevents that the horizontal load that the reason stocking yarn is applied on the knitting needle from causing the damage of knitting needle bending, braiding fault and knit stitches, and limits the bending of knitting needle.

In horizontal volume machine, also used the horizontal volume machine of four needle-bars that bilevel needle-bar respectively is set in front and back (for example with reference to the special fair 1-57173 communique of Japan).In the horizontal volume machine of four needle-bars, between the lower floor's needle-bar before and after can be combined in, needle-bar or the anterior lower floor and the upper strata at rear portion on the lower floor at rear portion and anterior upper strata, weave various knitted fabrics, can weave the knitted fabric of Duoing than the horizontal volume machine of two-needle bar class.Yet, shown in Figure 3 as the special fair 1-57173 communique of Japan, the interval between the end of the needle-bar of the upper layer side of tooth mouth is wideer than the interval between the end of the needle-bar of lower layer side.

In such horizontal volume machine of four needle-bars shown in the special fair 1-57173 communique,, also can carry out side supporting with the horizontal volume machine of two-needle bar same degree for the knitting needle of lower layer side needle-bar as Japan.For example, can carry out the supporting of knitting needle side in the same projections such as the real public clear 42-6263 communique of terminal part setting and Japan of needle-bar.But, in the needle-bar of upper layer side, since wideer in the face of the interval between the end of tooth mouth than the interval between the needle-bar end of lower layer side, the side supporting provided so be difficult to be provided with projection to knitting needle.

And then, because in upper layer side, the terminal position of needle-bar leaves from the tooth mouth, so increase under the braiding situation of loop density at for example needle-bar with upper layer side, even before the center of pinhock by the tooth mouth of the end that makes knitting needle, go out in opposite directions needle-bar side and after having received the supply of stocking yarn, knitting needle is retreated form the coil arc, the end of knitting needle still can become from the outstanding state of the end portion of needle-bar.Under such state, can't provide abundant supporting to the knitting needle of hold-in winding towards the side.

Summary of the invention

The purpose of this invention is to provide a kind of horizontal volume machine,, also can carry out sufficient supporting the knitting needle of upper layer side needle-bar at the side load even have two-layer needle-bar up and down in the same side in the face of the tooth mouth.

Fig. 5 is illustrated in the state of drawing in pin main body 23a among Fig. 1.The position of knitting needle support projection 11,12 is in the pin main body 23a of upper strata needle-bar 3a, 4a, the scope that 24a passes through, and, even also be set as pusher jack 25b, the 26b of the needle-bar 3b of lower floor, 4b by the time, except guiding with the end of the

wing plate

37,38 of Fig. 2 B explanation, can not produce the scope of interference.

Fig. 6 shows for the front side needle-bar 3 shown in the left side has identical effect at slave side, knitting needle support projection 11 and tooth mouth silk 13 from compound needle 21a, 21b knocking over.Knocking over auxiliary is to hang on knitting needle support projection 11 and the tooth mouth silk 13 and pull to tooth mouth below and to carry out by the old circle arc that will stride across pusher jack 25a, 25b.The position relation of knitting needle support projection 11 and pusher jack 25a is identical with the position relation of tooth mouth silk 13 and pusher jack 25b comparatively speaking, can carry out same assisting to knocking over.

Although above explanation is the explanation that the horizontal volume machine 1 at each two-layer needle-bar four needle-bars in opposite directions in the front and back of tooth mouth 2 carries out, if at least one-sided be two-layer.That is, at least one side of being equally applicable in the needle-bar of tooth mouth 2 front and back in opposite directions of the present invention has bilevel horizontal volume machine.The tooth mouth 2 side parts of the needle-bar 3b of lower floor, 4b in two-layer needle-bar, as long as so a plurality of fixedly sinkers 9,10 are set, that is, described fixedly sinker works as sinker to a plurality of knitting needles that carry out braid movement from relative tooth mouth 2 advance and retreat of the needle-bar 3b of lower floor, 4b and these both sides of a plurality of knitting needles that carry out braid movement from relative tooth mouth 2 advance and retreat of upper strata needle-bar 3a, 4a.On fixing sinker 9,10, in the position of the braid movement of the relative tooth mouth of the knitting needle of not interfering the needle-bar 3b of lower floor, 4b 2 advance and retreat and facing the position of the side of the knitting needle that does well before the relative tooth mouth 2 of knitting needle of upper strata needle-bar 3a, 4a, be provided with towards getting final product from going out before upper strata needle-bar 3a, the 4a to the outstanding knitting needle support projection 11,12 in side of the knitting needle of tooth mouth 2.Even be subjected to the load effect in the side, supported owing to contacting, so can suppress big bending with the fixing knitting needle support projection 11,12 of sinker 9,10 from going out before upper strata needle-bar 3a, the 4a to the knitting needle of tooth mouth 2.Because knitting needle support projection 11,12 is only outstanding in the side of knitting needle, thus different with the such feed-through of wire rod, little with the interference of knitting needle etc., be located at position near tooth mouth 2, can support knitting needle effectively.

In addition, for a plurality of knitting needles, there is no need to be provided with all knitting needle support projection 11,12.Because it is bigger in the side side of knitting width to act on the side load of knitting needle, so need become the end side of knitting width to the coil that the side load is assisted.Thereby, near the more position of the situation knitting width central authorities of in needle-bar, becoming, also knitting needle support projection 11,12 can be set.But, for the position that knitting needle support projection 11,12 is not set, need not produce big lateral load, braiding is produced restriction.If knitting needle support projection 11,12 is set in the front portion of needle-bar, then can not produce restriction to braiding.

The end portion of needle-bar also can be helpful when the old circle arc of the situation lower coil of making knit fabric relatively newly encloses the arc knocking over.Retreat from the tooth mouth preceding going out the knitting needle that stocking yarn is received on the pinhock to the tooth mouth, while draw in the new circle arc that stocking yarn forms coil.The old circle arc of Bian Zhi coil formerly, the mode that breaks away from pinhock with the pinhock of crossing over knitting needle is pulled by the knitted fabric of compiling out at the tooth mouth.The knitted fabric that links to each other with the old circle arc of coil is pulled into the direction of the end portion of needle-bar, and part changes direction downwards endways.In the end portion of needle-bar, if the hard parts such as piano wire that separate with needle-bar are installed in advance, then can reduce the friction of the stocking yarn of tooth mouth end portion, can help knocking over to carry out smoothly.

But, the end portion of upper layer side needle-bar is compared with the lower layer side needle-bar, owing to become the position that breaks away from from the tooth mouth, so, even be provided with the such wire rods such as piano wire of knocking over that help knitting needle, do not produce on the position of interference when going out to the tooth mouth before the knitting needle about yet must being configured in upper layer side.For the configuration that can realize preventing interfering, the upper layer side needle-bar also must dispose dividually with the lower layer side needle-bar.When the interval of needle-bar became big up and down, the increase loop density performance of needle knitting obviously reduced up and down mutually.For this reason, can not make the end portion of wire rod break-through upper layer side such as piano wire.Needing the auxiliary coil of knocking over is the end side of knitting width and since this coil towards the central authorities of knitting width by cross directional stretch, so from the knitting needle side outstanding projection also can to carry out sufficient knocking over auxiliary.

The present invention can be implemented with other variety of way under the situation that does not exceed its design or principal character.Therefore, all aspects of above-mentioned embodiment are example only, and scope of the present invention is illustrated by claims, is not subjected to any restriction of specification text.And the modification or the change that belong to claims are included in the scope of the present invention.

Industrial applicibility

According to the present invention, the front side needle-bar of horizontal volume machine and at least one party in the rear side needle-bar have Two-layer needle-bar up and down, the tooth mouth side of the lower layer side needle-bar in this two-layer needle-bar partly arranges a plurality of Fixing sinker. Fixedly sinker is to advancing and retreat from the relative tooth mouth with the upper layer side needle-bar of lower layer side needle-bar The knitting needle that ground carries out braid movement plays the effect of sinker. On fixing sinker, not with The position that the braid movement of the relative tooth mouth of the knitting needle of lower layer side needle-bar advance and retreat interferes and facing The position of the side of the knitting needle of the state that goes out before the relative tooth mouth of the knitting needle of upper layer side needle-bar, arrange to From going out before the upper layer side needle-bar to the outstanding projection in side of the knitting needle of tooth mouth. When knitting needle is subjected in the side When bending to load, contact with projection, can suppress big bending thus. Because prominent Rising only is that side to knitting needle is outstanding, thus different from the such feed-through of wire rod, with knitting needle etc. Interference little, be located at the position near the tooth mouth, can effectively support knitting needle.

In addition, according to the present invention, join respectively being set up in parallel between a plurality of knitting needles of each needle-bar Put fixedly sinker, fixedly projection is set respectively the two sides of sinker at each. Because projection court Fixedly sinker to each knitting needle from both sides is outstanding, so for appointing towards two sides of knitting needle The meaning load all can suppress big bending by projection.

In addition, according to the present invention, when for example public affairs in No. 3379947 communique of Japan Patent When going out to the tooth mouth before the pusher jack of the compound needle of opening, the end of two wing plates is subjected to and sinks from fixing Fall the guiding of the continuous inclination of the outstanding projection of sheet, thereby can reduce wing plate opening to the side. Since maintenance horizontal volume machine etc. manually during advance and retreat operation pusher jack or the cam that drives pusher jack from Track is thrown off and during misoperation, also can be guided reliably the end of wing plate. That is, can prevent The terminal impaired such accident of wing plate takes place when not arranging.

In addition, according to the present invention, can carry out simultaneously the lower layer side needle-bar by fixing sinker The side of knitting needle supporting and to the side supporting of the knitting needle of upper layer side needle-bar.
