Description

Flat needle knitting system, selector and flat knitting machine {NEEDLE SELECTION SYSTEM OF FLAT KNITTING MACHINE, SELECTOR, AND FLAT KNITTING MACHINE}

The present invention constitutes a needle needle system of a flat knitting machine in which needle needle miss is less likely to occur than a conventional configuration, and a part of the flat needle knitting machine and a needle needle system using the needle needle system. It is about selectors.

The flat knitting machine includes at least a pair of front and rear needle beds, a needle needle disposed in each of a plurality of needle grooves parallel to each needle bed, and a length direction of the needle bed (the direction of extension of the needle groove and And a carriage reciprocating along the orthogonal direction). The carriage is equipped with a knitting cam, which is used to knit the knitting needles (knit, tuck, miss, and stitches between the front and rear needle beds). Return). Which knitting operation is performed on each knitting needle is determined by picking the knitting needle by the needle needle system. As such a needle needle system, what employs an electron needle needle method (for example, refer patent document 1).

Fig. 7 is an explanatory diagram for explaining the electron needle needle type prior art needle system, showing the vicinity of the selector in the cross section of the needle bed. In this Fig. 7, the carriage 300 reciprocates in the depth direction of the ground. When the carriage 300 reciprocates, the needle needle 201 disposed in the needle groove 101 of the needle bed 100 is needled, and the needle needle 201 extends the needle groove 101 based on the needle needle result. It moves in the direction (right and left direction of the ground), and knits. The needle needle system shown in FIG. 7 is composed of a selector 9 provided in each knitting needle 201 and a needle needle device 2T provided in the carriage 300.

The knitting needle 201 includes a needle body (not shown in the drawing) having a hook, a needle jack 7 for retracting the needle body in the extension direction of the needle groove 101, and a needle. A select jack 8 for controlling whether or not the jack 7 is advanced and a selector 9 for changing the position of the select jack 8 in the extension direction of the needle groove 101; ). According to the position of the select jack 8, a knitting butt 71 provided in the needle jack 7 and a driving butt provided in the slider (shown in the drawing). The operating state of the knitting cam 30 is changed, and the knitting operation of the knitting needle 201 is also changed.

The select jacks 8 can take the following three positions B, H, and A in the extending direction of the needle grooves 101 (some may be two depending on the knitting machine). For example, the B position corresponds to miss knitting. The H position is a position on the needle bed gap side (the right side of the ground) than the B position, and corresponds to the jaw knitting or the transfer. The A position is a position on the needle bed gap side than the H position, and corresponds to the knit knitting or the transfer. These positions are held by two divided position support parts 82 on the trailing side of the select jack 8 (opposite to the needle bed gap side). Three recesses are formed in the position support portion 82, and the positions of the select jacks 8 are formed by engaging the wires 8w extending in the longitudinal direction (the depth direction of the ground) of the needle bed 100 to each recess. It is a decision.

The selector 9 for changing the position of the select jack 8 includes a base 91, a front end 92 formed on the needle bed gap side of the base 91, and a base 91. And a stator 93 formed on the trailing side of the () and an elastic angle piece 94 extending from the base 91 to the trailing side. Moreover, the rising butt 95 is formed in the upper end side of the contactor 93 (the surface side of the needle bed 100 from the upper side of the ground), and the lower end is lowered in the upper end side of the base 91. Butt 96 is formed. The selector 9 moves to the needle bed gap side by the needle needle cam 39, which will be described later, acting on the rising butt 95, and the butt 81 of the select jack 8 is moved from the tip portion 92 to the needle bed gap. The pressure is applied to the side to move the select jack 8 from the B position to the H position or the A position. Thereafter, the selector 9 is quickly returned to the B position, and provided to the next needle. In addition, the selector 9 is in the B position in a normal case, and the raising butt 95 of the selector 9 is in a state protruding from the needle groove 101.

On the other hand, the needle tip device 2T has a needle tip cam 39 facing the butts 95 and 96 of the selector 9 and a lower end face (adsorption end surface 93s) of the contactor 93 of the selector 9. A select needle actuator 10 is provided opposite the. The select needle actuator 10 is provided with an adsorption surface 10s through which permanent magnets are exposed, and the contactor 93 (sorption end surface 93s) of the selector 9 is provided on the adsorption surface 10s. It can be adsorbed. Here, two detachment regions are set in the suction direction 10s in the width direction (the depth direction of the ground), and in this detachment region, electricity is supplied to the select needle actuator 10. It is possible to weaken the magnetic force by the permanent magnet by the action of the generated electromagnetic force.

In the case of knitting by the flat knitting machine having the above configuration, when the carriage travels on the needle bed 100 and the select needle actuator 10 is close to the selector 9, the select needle actuator 10 The adsorption surface 10s adsorbs the contactor 93 of the selector 9 (the state before adsorption is shown in FIG. 7), and the rising butt 95 is sunk into the needle groove 101. This state is the so-called non-needle state. If the select needle actuator 10 is not energized, the needle tip cam 39 cannot act on the rising butt 95, and the selector 9 does not move to the needle bed gap side and is held at the B position.

On the other hand, when the carriage 93 moves in the state in which the contactor 93 of the selector 9 is adsorbed, and the contactor 93 starts to approach the detachment area of the adsorption surface 93s, the select needle actuator 10 When energization is made, the contactor 93 is separated from the suction surface 10s. In this case, the rising butt 95 rises from the needle groove 101 by the elastic force of the elastic angle piece 94 in contact with the upper end surface of the position support portion 82 of the select jack 8, and the rising butt ( 95, the needle tip cam (39) is in a state of acting. When the needle tip cam 39 acts on the rising butt 95 of the selector 9, the selector 9 moves to the needle bed gap side, and the tip portion 92 of the selector 9 moves to the select jack 8. The rising butt 81 of is extruded toward the needle bed gap side, and the position of the select jack 8 is also changed. The position of the selector 9 (select jack 8) changes depending on which of the two detachment areas is to be detached from the adsorption surface 10s in either of the two separation regions.

Japanese Patent No. 3459514

In recent years, the improvement of the knitting efficiency in a flat knitting machine is calculated | required further, and the review of the existing line needle system is examined.

In the needle tip device of FIG. 7, when the knitting speed is increased, the contactor 93 with respect to the suction surface 10s is caused by a slight variation in the distance between the carriage 300 and the needle bed 100 according to the running of the carriage 300. Adsorption and desorption of c) may become unstable, and there is a risk that a needle needle may occur. This is because the selector 9 is supported by both the needle bed 100 and the carriage 300 when the contactor 93 of the selector 9 is attracted to the suction surface 10s. Here, a spring point 94b for generating an elastic force of the elastic angle piece 94 is formed on the upper surface of the position support portion 82 of the select jack 8 to which the elastic angle piece 94 of the selector 9 is in contact. As the carriage 300 moves, the elastic force of the elastic angle piece 94 which acts in the direction in which the pole 93 is lifted from the needle groove 101 is slightly changed, so that the adsorption and release are unstable.

Moreover, in the structure shown in the figure, since the position of the spring point 94b and the position of the to-be-adsorbed end surface 93s of the contactor 93 are shifted in the longitudinal direction of the needle groove 101, It is easy to generate a big moment around. This is also a factor in which adsorption and detachment of the contactor 93 to the adsorption surface 10s are not stable.

In addition, when the flat knitting machine is formed into a fine gage, the width of the contactor 93 of the selector 9 becomes thin, and the area of the end surface 93s to be adsorbed becomes small. Also in this case, adsorption and detachment of the contacts 93 to the adsorption surface 10s become unstable.

This invention is made | formed in view of the said situation, One of the objectives is to provide the needle needle system of the flat knitting machine which can perform needle needle more stably than before, and the selector used for the needle needle system. Another object of the present invention is to provide a flat knitting machine to which the needle needle system of the flat knitting machine is applied.

A needle needle device which is installed in a selector and a carriage reciprocating in the longitudinal direction of the needle bed and changes the knitting operation performed on the knitting needle by changing the position of the selector along the extending direction of the needle groove. Iii). The needle tip device is arranged in the depth direction of the needle groove by leaving a part of the selector adsorbed on the adsorption surface on which a part of the selector is adsorbed by a magnetic force or being separated from the adsorption surface. And a select needle actuator for selecting the single needle by changing the position of the selector. The selector of the needle needle system of the present invention includes a base, a tip end portion formed on a needle bed gap side of the needle bed in the base, and a needle bed gap side in the base. A contactor formed on the opposite end side and arranged to face the suction surface of the select needle actuator, and an elastic angle piece connected to the distal end and extending toward the end end side;性 脚 片 is provided. Further, the needle tip device of the needle tip system of the present invention is provided in addition to the select needle actuator and protrudes at a position facing the select needle actuator, and the contact of the selector when the carriage travels on the needle bed. An interrupt cam is inserted between the pole and the elastic angle pieces to widen the gap therebetween, so as to attract the pole to the suction surface of the select needle actuator. In the needle tip system of the present invention having the above configuration, the elastic angle pieces of the selector contact the interrupt cam while the interrupt cam passes through the selector, and the selector is supported by the interrupt cam by the contact.

As a form of the needle needle system of the flat knitting machine in this invention, it is preferable that the contact part formed in the elastic square piece of the said selector is arrange | positioned in the formation range of the said contact | pole in the extension direction of the said needle groove. Do. Here, a contact part is a part which contacts the said interrupt cam among the elastic angle pieces of the said selector, and is a part used as a spring point which generate | occur | produces the elastic force which presses the said contactor in the direction approaching an elastic angle piece.

As a form of the needle needle system of the flat knitting machine in this invention, it is preferable that the said select needle actuator is provided in the said carriage so that it may contact the pole of the said selector from the upper surface side of the said needle bed.

As a form of the needle knitting system of the flat knitting machine in this invention, the rising butt is formed in the opposite side to the to-be-adsorbed end surface adsorb | sucked to the said select needle actuator among the contactor of the said selector, The said interrupt The cam is preferably formed with a guide for acting on the rising butt to advance the selector to the needle bed gap side.

On the other hand, the selector of the present invention is a member constituting a part of the knitting needle disposed in each of the needle groove parallel to the longitudinal direction of the needle bed of the flat knitting machine, the knitting by the knitting needle by the position along the extension direction of the needle groove It is a member that determines the operation. The selector of this invention is a base, the front-end | tip part formed in the one end side of the longitudinal direction of the said base body, the contactor formed in the other end side of the longitudinal direction of the said base body, and the said front-end | tip part It is provided with an elastic angle piece connected to and extending toward the other end side. And the elastic angle piece of this selector is an elastic force which contacts a member when the member fixed to the carriage of a flat knitting machine is inserted between the said pole and an elastic angle piece, and presses the said elastic force in the direction approaching the said elastic angle piece. It has a contact portion which becomes a spring point to generate | occur | produce.

EMBODIMENT OF THE INVENTION Hereinafter, the flat knitting machine which applied the piercing system of the flat knitting machine in this invention is demonstrated based on drawing.

<Overall configuration>

The flat knitting machine of the present embodiment includes at least a pair of front and rear needle beds, a plurality of knitting needles parallel to each needle bed, and a carriage for reciprocating on the needle bed. This is a machine for knitting a knitted fabric by operating each knitting needle by a knitting cam mounted on a carriage. The flat knitting machine described in this embodiment is characterized by a needle needle system for changing the knitting operation of the knitting needle. This needle needle system is provided with the needle needle which comprises a select needle actuator and an interrupt cam, and the selector which comprises a part of partial needle, as mentioned later, Both of them have a structure different from the conventional one. First, the knitting operation of the flat knitting machine in this embodiment will be briefly described first with reference to FIG. 1, and then, with reference to FIGS. It demonstrates in detail.

The knitting needle 200 according to the present embodiment shown in FIG. 1 includes a needle body 5, a slider 6, a needle jack 7, and a select jack 8 ) And a selector 4. The needle body 5 has a hook for engaging the knitting yarn. The slider 6 opens and closes the hook of the needle body 5. The needle jack 7 advances the needle body 5 in the extension direction of the needle groove (up and down direction of the surface). The select jack 8 controls whether the needle jack 7 moves forward or backward by its position in the extension direction of the needle groove. The selector 4 changes the position of the select jack 8 in the extension direction of the needle groove (the selector 4 constituting the needle needle system 1 will be described later). The members 6, 7, 8, and 4 are provided with single or plural butts. The members 6, 7, 8, and 4 advance and retreat in the direction of extension of the needle groove by acting on the knitting cam 30 to be described later and the needle tip device 2 to be described later. The knitting needle used in the flat knitting machine of the present embodiment may be a latch needle.

On the other hand, a knitting cam 30 having a plurality of cams 31 to 36 is attached to the carriage 300 of the flat knitting machine, and the knitting cam 30 acts on each butt of the knitting needle 200 to form a knitting operation. This is done. Of course, the knitting cam 30 may be mounted in plural carriage 300. In FIG. 1, the slider guide cam which acts on the drive butt 61 of the slider 6 is abbreviate | omitted, The direction of the knitting needle 200 is shown by the state different from an actual direction. .

Next, the knitting operation of the knitting needle 200 will be described based on the trajectories of the butts 71, 83, 45, and 46 provided in the knitting needle 200 shown by broken lines in FIG. Here, the trajectories of the butts 71, 83, 45 and 46 are divided into three, and are trajectories when the B position, the H position and the A position are respectively sequentially from the lower side of the ground.

First, when the selector 4 is held in the B position by the needle needle 2 described later when the carriage 300 has traveled, a pressurized butt 83 of the select jack 8 is applied. ) Is sunk into the needle groove by the fixed presser 33, and the knitting butt 71 of the needle jack 7 is also sunk into the needle groove. In this case, the knitting butt 71 is not affected by the needle raising cam 31 and moves to the needle bed gap side (upper direction of the ground), which is the extension direction of the needle groove. I never do that. As a result, the knitting operation becomes a miss knitting.

Second, when the selector 4 is moved to the H position by the needle needle 2 described later, the select jack 8 also becomes the H position. In this case, the knitting butt 71 moves to the needle bed gap side under the action of the needle rising cam 31. Here, the movable presser 34 is arrange | positioned in the position which overlaps with the trace | route of the pressurization batt 83 in H position. For this reason, the pressing butt 83 sinks into the needle groove by the movable presser 34, and accordingly, the knitting butt 71 also sinks into the needle groove, and the knitting butt 71 is the needle rising cam below the ground. The projections pass through the projections without being affected by the projections in the middle of (31). Thereafter, the knitting butt 71 is lowered to the opposite side to the needle bed gap by a stitch cam 32 on the left side of the paper. As a result, the knitting operation becomes a tuck knitting. In addition, the pressing butt 83 in the H position is lowered to the B position by the select jack lower cam 36 on the left side of the ground, and the lowering butt 46 in the H position is provided. Is lowered to position B by the selector lowering cam 35 on the right side of the ground.

Thirdly, when the selector 4 is moved to the A position by the needle needle 2 described later, the pressurized butter 83 also becomes the A position. In this case, the knitting butt 71 is raised to the needle bed gap side under the action of the needle rising cam 31 and then lowered to the opposite side to the needle bed gap under the action of the stitch cam 32. As a result, the knitting operation becomes a knit knit. Further, the pressurizing butt 83 and the lowering butt 46 in the A position are lowered to the B position by the cams 36 and 35, respectively.

<Needle needle system>

As described above, the position of the selector 4 of the knitting needle 200 defines the knitting operation of the knitting needle 200. The needle needle system 1 of this embodiment is comprised by this selector 4 and the needle needle 2 which changes the position of the selector 4. As shown in FIG.

≪Selector≫

As shown in Fig. 2 and Fig. 4, the selector 4 is a substantially hairpin-shaped plate-like member, which has a base 41, a tip 42, and a stator. 43, an elastic angle piece 44, an upward butt 45 and a downward butt 46 are provided.

The base 41 is a rod-shaped portion extending along the longitudinal direction of the needle groove 101 when the selector 4 is disposed in the needle groove 101.

The distal end portion 42 is an approximately L-shaped portion disposed on the needle bed gap side of the needle bed 100 when the selector 4 is disposed in the needle groove 101, and is a rising butt (for the select jack 8). It is a part for pushing 81 from the end side to the needle bed gap side. The tip 42 has a lowering butt 46 for protruding upward of the needle bed 101. This lowering butt 46 always protrudes from the needle groove 101 regardless of the position of the selector 4, and is a portion to which the selector lowering cam 35 acts as already described with reference to FIG. 1.

The contactor 43 is a plate-shaped part disposed on the side opposite to the needle bed gap (end side) when the selector 4 is disposed in the needle groove 101. The upper end surface of the contactor 43 is an end surface 43s to be adsorbed by the adsorption surface 10s of the select needle actuator 10 described later. In addition, the rising butt 45 is formed to protrude from the lower end surface of the contactor 43 toward the bottom of the needle groove 101 (downward of the needle bed 100). The rising butt 45 is a portion which receives the action of the interrupt cam 20 described later.

One end of the elastic angle piece 44 is connected to the distal end portion 42, and the other end thereof is a rod-shaped portion of a free end, and is spaced apart from the base 41. Parallel to the gas 41. The other end of the elastic square piece 44 extends in the longitudinal direction of the selector 4 (that is, the direction in which the needle groove 101 extends) to the position facing the pole 43. The other side of the elastic angle piece 44, which is opposite to the pole member 43, is in contact with the interrupt cam 20 to be described later to generate an elastic force for pressing the pole 43 toward the bottom of the needle groove 101. A contact portion 44b serving as a spring point is formed. In the middle portion of the elastic square piece 44, a coupling portion 44h bent in a semicircular arc shape is formed. As shown in Fig. 4, the engaging portion 44h is coupled to the wires 4w and 5w extending in the longitudinal direction of the needle bed 100 when the selector 4 is disposed in the needle groove 101. The position of the selector 4 in the groove 101 is determined.

<< needle needle device >>

The needle needle device 2 includes a select needle actuator 10 and an interrupt cam 20 as shown in Figs. 3A and 3B. Among these, the select needle actuator 10 is provided with the coupling part which can attach the interrupt cam 20, and the basic structure is the same as that of the conventional thing. Specifically, the select needle actuator 10 is a surface on which a plurality of permanent magnets 11 are exposed, and has a suction surface 10s for adsorbing the pole 43 of the selector 4 (in particular, FIG. 3). (C)). On the suction surface 10s, separation regions 12a and 12b are formed between the permanent magnets 11 and 11 which are parallel to the width direction of the select needle actuator 10 (same as the traveling direction of the carriage). . When energizing the electromagnetic coil incorporated in the select needle actuator 10, the magnetic force in the separation regions 12a and 12b is weakened.

As shown in FIG. 4, the select needle actuator 10 is disposed in the carriage 300 such that the suction surface 10s faces the upper surface of the needle bed 100. As shown in FIG. For this reason, if the select needle actuator 10 moves closer to the selector 4 by moving the carriage 300 in the depth direction of the ground, the suction surface 10s becomes the contactor 43 of the selector 4 (FIG. 2). It comes in contact with the end surface 43s to be absorbed. In addition, the needle needle device 2 in FIG. 4 is located on the depth direction side of the ground surface than the single needle needle 200.

On the other hand, the interrupt cam 20 constituting the needle tip device 2 is attached to the select needle actuator 10 as shown in Figs. 3A, 3B, and 3D, and the select needle actuator It is a member protruding to a position opposite to 10. The role of the interrupt cam 20 is to be interposed between the pole 43 of the selector 4 and the elastic angle piece 44 to widen the interval between the pole 43 and the elastic angle piece 44, thereby providing a pole ( 43) is made to adsorb | suck to the adsorption surface 10s of the select needle actuator 10 (refer FIG. 5 and its description later). The interrupt cam 20 also serves to support the contact portion 44b of the elastic angle piece 44 provided in the selector 4 so that the selector 4 is not supported by the needle bed 100 (described later). 5 and its description). In addition, the interrupt cam 20 of this embodiment also has the role of the sun needle cam 39 of the conventional structure shown in FIG.

An inclined surface 21, an upper surface 22, and a middle surface of the interrupt cam 20 are disposed on the side opposite to the suction surface 10s of the select needle actuator 10. 23 and the bottom surface 24 are formed. The inclined surface 21 of the interrupt cam 20 rises toward the middle portion from the widthwise end of the interrupt cam 20 and is connected to the upper surface 22. The upper surface 22 is a flat surface having an approximately M shape. The stopping surface 23 is an approximately M-type flat surface that is bent toward the end side (upper side of the paper in Fig. 3D) from the widthwise end portion of the interrupt cam 20 toward the middle portion. Bottom surface 24 is a flat surface that is approximately mountainous. Between the middle surface 23 and the lower surface 24, wall portions 20b are formed in addition to the step formed by the height difference between the middle surface 23 and the lower surface 24. The wall portion 20b is formed only forward than the middle portion of the width direction of the interrupt cam 20, and therefore, a route descending from the interruption surface 23 to the lower surface 24 is formed. The height of this wall part 20b becomes substantially the same as the height of the upper end surface 22 (refer FIG. 3 (A), (B)).

As described above, a plurality of surfaces 21 to 24 having different heights are formed on the upper surface of the interrupt cam 20. Three guide routes (B, H, A) for guiding the raising butt 45 of the selector 4 by the step between these surfaces 21 to 24 (two dashed chains in FIG. 3 (D)). Lines and squares) are formed. Each guide route B, H, A corresponds to the B, H, A positions of the selector 4, respectively. In other words, the interrupt cam 20 of the present embodiment also serves as a front needle cam for raising the raising butt 45 of the selector 4 toward the needle bed gap side.

It demonstrates concretely how the needle tip of the knitting needle 200 is performed by the needle tip system 1 provided with the structure demonstrated above.

First, when the carriage needle 300 is driven from the state of FIG. 4 and the needle needle 2 approaches the knitting needle 200, the widthwise end of the interrupt cam 20 of the needle needle 2 is a pole of the selector 4. (43) (FIG. 2) is sandwiched between the elastic square pieces 44. As shown in FIG. When the carriage 300 advances, as shown in Fig. 5A, the inclined surface 21 of the interrupt cam 20 is placed on the rising butt 45 at the lower end of the pole 43, and the interrupt cam ( The lower end surface 29 (FIG. 3 (B)) of 20 contacts the contact part 44b in the upper end surface of the elastic angle piece 44, and presses between the contactor 43 and the elastic angle piece 44, Widen The rising butt 45 reaches the upper end surface 22 of the interrupt cam 20, and the contactor 43 is attracted to the suction surface 10s of the select needle actuator 10. As shown in FIG. At this time, the elastic angle pieces 44 of the selector 4 are in contact with the interrupt cam 20 at the position of the contact portion 44b, and the selector 4 is supported by the carriage 300. Accordingly, even if the interval between the needle bed 100 and the carriage 300 is slightly changed, the adsorption of the selector 4 by the suction surface 10s is hardly affected by the variation. At this time, it is preferable that the selector 4 is completely separated from the wires 4w and 5w so that the selector 4 does not depend on the needle bed 100. In addition, the rising butt 45 and the upper end surface 22 are slightly isolated.

Here, even when the selector 4 is not supported by the needle bed 100, the moment is applied to the suction end surface 43s of the contactor 43 due to the vibration of the carriage 300 accompanying the running of the carriage 300. May act, and the contactor 43 of the selector 4 may detach from the adsorption surface 10s. On the other hand, in this embodiment, the contact part 44b which contacts the interrupt cam 20 among the elastic angle pieces 44 becomes a spring point which presses the contactor 43 toward the needle groove 101, and the spring point Since the contact portion 44b is positioned at the position overlapping with the formation range of the suction end surface 43s of the contactor 43 in the extending direction of the needle groove 101, the spring portion 44b has a center. Moment is hard to occur. For this reason, in order to detach the contactor 43 from the adsorption surface 10s without using the electromagnetic force of the select needle actuator 10, it is necessary to apply a considerable force, and to follow the travel of the carriage 300 As for the vibration degree of the carriage 300, the contactor 43 hardly separates from the adsorption surface 10s.

As described above, if the contactor 43 is not detached in the state of being adsorbed to the suction surface 10s, the rising butt 45 is floating from the upper surface 22 of the interrupt cam 20. The guide route B shown in (D) is moved, so that it is not affected by the interrupt cam 20. As a result, the selector 4 does not move in the extension direction of the needle groove 101 to maintain the B position. In this case, the knitting operation of the knitting needle 200 becomes a miss knitting.

On the other hand, when the contactor 43 is separated from the first separation region 12a of the select needle actuator 10 shown in FIG. 3D, the rising butt 45 moves the guide route A. FIG. . Specifically, as shown in FIG. 5B, the rising butt 45 separated from the disengagement region 12a is formed of the elastic angle piece 44 supported by the lower end surface 29 of the interrupt cam 20. It is pressed toward the bottom of the needle groove 101 by the elastic force, and falls to the position of the interruption surface 23 of the interrupt cam 20. In addition, when the carriage 300 runs, the rising butt 45, as shown in Fig. 3D, has a guide g1 formed by the step between the top surface 22 and the stop surface 23. It is thus pushed toward the needle bed gap and falls to the bottom face 24. The rising butt 45 dropped to the lower end face 24 is further pushed toward the needle bed gap side along the guide g2 formed by the step between the stop face 23 and the lower end face 24, and as a result, the selector (4) becomes A position as shown in FIG. Here, since the wall portion 20b is formed between the lower surface 24 and the middle surface 23, the rising butt 45 passes over the guide g2 by the vibration of the carriage 300 or the like. You do not ride the route (H).

Next, as shown in Fig. 3D, when the contactor 43 passes through the first release area 12a of the select needle actuator 10 and leaves the second release area 12b, The raising butt 45 moves the guide route H. As shown in FIG. Specifically, the rising butt 45 falls to the interruption surface 23 on the right side of the ground of the interrupt cam 20, and is formed by the step between the upper surface 22 and the interruption surface 23. Along the needle bed gap side. As a result, the selector 4 becomes an H position. In this case, the rising butt 45 is excessively moved toward the needle bed gap side by the wall portion 20b formed in the interrupt cam 20 so as not to ride the guide route A.

In addition, this invention is not limited to said embodiment, It can change suitably and can implement in the range which does not deviate from the summary of this invention. For example, the select needle actuator 10 is in contact with the selector 4 from the bottom surface side of the needle bed 100 and sinks the selector 4 into the needle groove 101 so as to be in a non-precipitating state. The configuration may be performed. In this case, the interrupt cam 20 may be disposed on the upper surface side of the needle bed 100 rather than the suction surface 10s of the select needle actuator 10. Moreover, the contact part 44b which the interrupt cam 20 in the selector 4 contacts is located outside the formation range of the to-be-adsorbed end surface 43s of the pole 43 in the extension direction of the needle groove 101. As shown in FIG. You may be. In addition to this, the interrupt cam 20 of this embodiment functions as a sun needle cam that changes the position of the selector 4 by providing the guides g1 to g3, but is an interrupt cam that does not serve as the sun needle cam. You may. In this case, it is necessary to prepare a needle needle cam separately.
