Abstract

The invention provides a glove knitting machine which can knit while overlapping finger roots between finger bags and can improve the quality of gloves. The tucking cam is provided with a return cam surface on the needle bed gap side for returning the knitting needles that hold the stitches of the finger pocket knitted first to the needle bed gap side at the operating position shown by the solid line, and functions as a return cam. The stitch presser is driven by a driving cam provided on the needle bed side so as to draw the knitting needle to the needle bed side in an operating position shown by a broken line, in order to facilitate the stitch presser to act on the knitting needle for locking the stitch at the base of the finger pocket knitted first to the hook. The return amount of the knitting needle for locking the stitch of the previously knitted finger pocket can be adjusted by the adjusting means so that the stitch having a different appearance or texture is less likely to be formed in the course direction and the miss of the stitch from the knitting needle is less likely to be formed. The adjustment by the return cam is also effective when the stitch suppressing plate is pulled out from the base of the finger after the subsequent knitting of the finger pocket.

Description

Glove knitting machine

Technical Field

The present invention relates to a glove knitting machine which knits gloves with finger pockets as a tubular knitted fabric and includes a stitch inhibiting plate for performing finger-root overlapping (japanese: thigh weight 12397.

Background

Conventionally, a glove knitting machine that forms gloves and the like by sequentially knitting finger pockets while overlapping finger bases has a pair of front and rear needle beds, and is provided with a band-shaped stitch inhibiting plate at the tip on the needle bed gap side between the needle beds (see, for example, patent document 1). In patent document 1, the stitch presser plate corresponds to a coil suppressing plate. The needle bed has needle plates arranged at a constant pitch in the longitudinal direction. Knitting needles are accommodated in needle grooves between needle plates and arranged in the longitudinal direction of the needle bed, and a knitted fabric is knitted by advancing and retreating hooks at the tip toward needle bed gaps. The knitting needles are moved back and forth by cams mounted on a carriage that reciprocates in the longitudinal direction of the needle bed.

The cams mounted on the carriage include a stitch forming cam used for knitting a stitch (japanese: degree mountain 1245912512), a tucker cam used when a stitch suppressing plate is caused to function (japanese: 12503125124124831247112515. The stitch cam functions in the following manner: a knitting needle receiving a supply of a knitting yarn at a needle bed gap on a hook at a stitch forming time is introduced to a needle bed side. The lead-in amount by the stitch cam corresponds to a coil size value (japanese: a value of a magnetic field) indicating the size of the coil. In order to reduce the weight of the carriage, the stitch cam is driven by a control rod from the outside of the carriage to adjust the size of the stitch in the glove knitting machine (see, for example, patent document 2). Cams used for forming coils other than the stitch cam are also driven by a control rod from outside the carriage to adjust the degree of action (see, for example, patent document 3). Patent document 3 describes a stitch cam as one movable cam that can switch between operation and non-operation by a control rod.

The stitch suppressing plate has a stitch suppressing groove extending in the longitudinal direction and having a shape opened to one side at a position separated from the tip of the needle bed side toward the needle bed side. The loop suppressing groove having such a shape is used for knitting a finger pocket adjacent to the finger pocket knitted earlier on the other side in the longitudinal direction while overlapping the finger roots. When the stitch restraining plate moves from the other side in the longitudinal direction with respect to the knitting needle holding the stitch at the base of the finger pocket knitted first and the stitch at the base of the finger is caused to enter the stitch restraining groove, the stitch is caused to stay on the needle bar immediately above the stitch restraining groove to restrain the loop from being dropped. When the stitch presser is operated, the knitting needle which holds the stitches at the base of the fingers on the hook is operated to pull the knitting needle toward the needle bed, and the stitches are likely to enter the stitch holding grooves. The knitting needles are used for knitting the toe portions of the adjacent finger pockets at the side of the needle bed gap with respect to the stitch suppressing grooves. When the knitting of the next finger pocket is finished, the stitch restraining plate is moved to the other side in the longitudinal direction, and the stitch restraining groove is separated from the stitch at the base of the finger to the other side. The stitches at the base of the finger pocket knitted first are returned to the needle bed gap side through the inclined portion of the stitch suppressing plate, and are overlapped with the stitches at the base of the finger of the next finger pocket knitted on the needle bed gap side. When knitting a knitted fabric of a main body portion continuous with two finger pockets, stitches at two finger base portions are left as overlapped stitches to form finger base portions where the finger bases are overlapped.

In recent years, a glove knitting machine is desired to knit a relatively thin glove such as a coated glove or a precision work glove using a relatively thin knitting yarn. However, when the knitting yarn is thinned, a problem is likely to occur when the stitch restraining plate is pulled out from the base portion of the finger and the stitch staying in the stitch restraining groove is returned to the needle bed gap side along the inclined portion. The finer knitting yarn is easily caught and sandwiched in the gap for sliding between the upper surface of the stitch inhibiting plate and the bottom surface of the needle plate or the bottom surface of the knitting needle. When the knitting yarn is caught in the gap, the state in which the stitches of the finger bases of the finger pockets knitted first are not released continues. The stitches are released and unraveled after being stretched while the knitting of the knitted fabric of the main body portion progresses. Such a knitted fabric product with delay of knocking-over becomes a product of poor quality.

The needle plates are a plurality of plate-like members arranged side by side on a base plate of the needle bed to form the needle bed. The knitting needles are a plurality of needle-like members which are accommodated in needle grooves between needle plates and which advance and retreat with respect to needle bed gaps. Since these members need to slide on each other, they cannot be closely attached to each other, and a gap to be caught is generated in the thin knitting yarn. Patent document 1 implements the following measures: the end face of the portion corresponding to the inclined portion of the stitch suppressing groove is formed as an inclined surface, and even a thin knitting yarn is less likely to bite into the gap between the upper surface of the stitch suppressing plate and the bottom surface of the needle plate or the like. However, it is difficult to prevent the biting of the thin knitting yarn by taking measures against the shape of the stitch suppressing groove.

In order to reliably perform the knocking-over, the knitted fabric needs to be pulled down below the needle bed gap in advance. However, since the glove knitting machine starts knitting the respective finger bags from the fingertips in order, a pull-down device or the like that pulls down the entire knitted fabric such as the knitted finger bag to the lower side of the mouth cannot be used. Therefore, the glove knitting machine uses movable sinkers which function as sinkers at the time of stitch formation and have a function of pushing down the knitted fabric between knitting needles to a lower side of the needle bed gap. However, when knitting the subsequent finger bag, the carriage also enters the knitting needle zone of the finger bag before knitting, and the movable sinker is driven by the sinker cam. Therefore, during knitting of the subsequent finger pocket, the sinker loop that locks the needle loops of the stitches of the finger pocket knitted first between the knitting needles of the hooks is pushed down by repeated advancing and retracting of the movable sinker in a state of tension at the time of stitch formation. The following problems may also arise: the loops including these sinker loops are pushed down by the movable sinker multiple times, and thereby become stripes in the course direction having a different appearance or texture from the loops not pushed down, and the quality of the formed glove is deteriorated.

Disclosure of Invention

The invention aims to provide a glove knitting machine which can improve the quality of gloves by knitting while overlapping the finger roots between finger bags by the action of a stitch restraining plate.

The invention is a glove knitting machine, comprising: knitting needles and movable sinkers which are arranged in a longitudinal direction of the front and rear needle beds, respectively; and

a coil-restraining plate is provided on the coil-restraining plate,

the glove knitting machine sequentially knitting a plurality of finger bags while overlapping the finger bases, which act on the finger bases, with the stitch inhibiting plates by using the cam-driven knitting needles and the movable sinkers mounted on the carriage reciprocating in the longitudinal direction, the glove knitting machine being characterized by further comprising:

a return cam for driving a knitting needle for engaging a stitch at a finger base portion so as to return to a needle bed gap side immediately before moving a stitch suppressing plate away from a finger pocket after the stitch suppressing plate is made to act on the finger base portion of a finger pocket knitted first and a subsequent finger pocket is knitted; and

an adjusting unit that adjusts a return amount of the knitting needle generated by the return triangle.

In the present invention, the return cam is a stitch cam which is driven by a driving cam surface provided on the needle bed side so as to draw in the knitting needle to the needle bed side in order to facilitate the stitch suppressing plate to act on the knitting needle which locks the stitch at the base finger portion of the previously knitted finger pocket to the hook,

a return cam surface for returning the knitting needles for locking the stitches of the previously knitted finger pocket to the needle bed gap side is provided on the needle bed gap side of the needle presser cam.

In the present invention, the return cam is a stitch cam for drawing the knitting needle to the needle bed side in accordance with the size of the stitch to be formed,

the stitch cam has a return cam surface on the needle bed gap side, and the return cam surface returns the knitting needle, which engages the stitch of the previously knitted finger pocket, to the needle bed gap side.

the stitch cam has a return cam surface on the needle bed side, and the return cam surface returns the knitting needle, which engages the stitch of the previously knitted pocket, to the needle bed gap side.

In addition, in the present invention, the adjusting means further includes: a control rod disposed outside the carriage, extending in a moving direction of the carriage, and displaced according to an adjustment amount of an adjustment unit; and

a rod mechanism that drives the return triangle according to a displacement amount of a control rod.

According to the present invention, when sequentially knitting the finger pockets while activating the stitch inhibiting plates, the return amount of the knitting needles that engage the stitches at the base of the fingers of the finger pocket knitted first can be adjusted by the adjusting means to return to the needle bed gap side by the return cam immediately before the stitch inhibiting plates are moved so as to be away from the knitted finger pockets. The stitch restraining groove of the locking stitch restraining plate restrains the adjustment of the return amount of the knitting needle of the stitch at the finger root of the doffing, thereby reliably performing the doffing and improving the quality of the glove. Before the start of knitting or during knitting of the subsequent finger bag, the knitting needle that holds the stitch of the finger bag knitted first can be returned by the return cam. By returning the knitting needle, even if the movable sinker pushes down a plurality of times, the knitting needle can be adjusted so that the stitch is less likely to have stripes with different appearances or different hand feels in the course direction and that the miss of the stitch from the knitting needle is less likely to occur.

Further, according to the present invention, the stitch presser acting on the knitting needle so as to draw in the stitch from the needle bed side to the needle bed side before the stitch restraining plate acts on the stitch to which the knitting needle at the finger root is locked can function as the return cam after the action of the stitch restraining plate. The needle pressing cam as the return cam can adjust the return amount by using a cam surface provided on the side of the notch.

Further, according to the present invention, the stitch cam functioning as the return cam can use the upper portion on the side of the notch as the cam surface, and the mechanism for adjusting the size of the stitch can be used for adjusting the return amount.

Further, according to the present invention, the stitch cam functioning as the return cam can be used as a cam surface on the lower side of the bed, and the mechanism for adjusting the stitch size and the needle selecting mechanism can also be used for adjusting the return amount.

Further, according to the present invention, in adjusting the amount of return of the return cam by the control bar from the outside of the carriage, even if the amount of return can be adjusted, the space and weight of the carriage can be prevented from increasing.

Detailed Description

Hereinafter, fig. 1 to 7 relate to the structure and operation of the glove knitting machine 1 as embodiment 1 of the present invention. Fig. 8 and 9 relate to operations of embodiment 2 and embodiment 3 of the present invention. Corresponding parts in the drawings are denoted by the same reference numerals, and redundant description may be omitted. For convenience of explanation, parts not shown in the drawings to be explained may be referred to by reference numerals shown in other drawings.

Example 1

Fig. 1 shows a triangular arrangement of a glove knitting machine 1 as embodiment 1 of the present invention. The glove knitting machine 1 includes a pair of needle beds which face each other in the front-rear direction with the needle bed gap 2 therebetween and are arranged at positions symmetrical with respect to the virtual center plane 2a. However, in FIG. 1, the needle bed is not shown. The front and rear needle beds are respectively provided with carriages 3F and 3B that reciprocate in the longitudinal direction. The longitudinal direction of the needle bed corresponds to the lateral direction in the figure. The carriages 3F, 3B have cams 10F, 10B, respectively, facing the needle bed surface. A cannonball cam 11 is mounted on a cam plate 10F of a carriage 3F of the front needle bed, and a rib cam 12, a middle cam 13, a stitch cam 14, a needle raising cam 15, a needle depressing cam 16, a needle guiding cam 17, and a needle depressing cam 18 are mounted on cam plates 10F, 10B of front and rear carriages 3F, 3B. These cams are the same as those described in patent document 3 except for the stitch cam 16.

The stitch cam 16 of the present embodiment 1 is provided with a return cam surface 16a and a drive cam surface 16b, and functions as a return cam for returning the knitting needle to the needle bed gap 2 side even at an operating position shown by a solid line where the stitch cam of patent document 3 provided with only the drive cam surface 16b is not operated. The stitch cam 16 functions to draw the knitting needle to the needle bed side by a driving cam surface 16b provided on the needle bed side in an operating position indicated by a broken line, similarly to the stitch cam of patent document 3. This function is for making the stitch inhibiting plate easily function with respect to the knitting needle that seizes the stitch at the base of the finger pocket knitted first to the hook. The adjustment means described later can drive the stitch cam 16 to move up and down along the drawing, switch the function by moving between two operating positions, and switch between adjustment of each operating position and non-operation in the middle.

Fig. 2 and 3 show the structure and operation of the main part inside the carriage 3F used in the glove knitting machine 1 of fig. 1, in a plan view of (a) and a right side sectional view of (b). The carriage 3B of fig. 1 is also substantially the same. Fig. 2 shows a state in which the stitch cam 16 functions as a return cam using the return cam surface 16a, and fig. 3 shows a state in which the drive cam surface 16b is used. The needle pressing cam 16 moves along the guide groove 16c in the vertical direction. The needle presser cam 16 is driven and the function is switched by a lever mechanism 20 mounted on the carriage 3F. The lever mechanism 20 includes a lever 21, a slider 22, a spring 23, and a roller bearing 24. The lever 21 has two arms, and the tip of one arm is engaged with the slider 22 and pulled by the spring 23. The slider 22 moves up and down along the guide groove 16 c. The roller bearing 24 is attached to the tip of the other arm of the lever 21, and may be replaced with a spherical or arc-shaped member. (b) The guide shaft 25 shown guides the movement of the carriage 3F in the longitudinal direction of the needle bed.

The guide member 30 is provided so as to extend in the longitudinal direction in the vicinity of the movement path of the carriage 3F, and supports the

control rods

31, 32, 33, and 34 extending in the longitudinal direction in a state of being capable of vertical displacement in the drawing. The roller bearing 24 is urged by a spring 23 so as to be in pressure contact with a side edge of one control rod 31. The displacement of the control rod 31 in the up-down direction angularly displaces the rod 21 and vertically displaces the slider 22. The slider 22 is connected to the stitch cam 16. The rod mechanism 20 drives the stitch cam 16 in accordance with the displacement amount of the control rod 31. The operating state of the needle pressing cam 16 is switched and at least the amount of return as a return cam is adjusted by mounting a stepping motor or the like on a drive device provided at the end in the longitudinal direction and driving the control rod 31. The control rod 31 and the rod mechanism 20 constitute an adjusting unit of the present invention. The adjustment by the adjusting means can be performed by driving a motor or the like provided outside the carriage 3F, similarly to the coil size adjustment of the stitch cam in patent document 2 and the operation of the movable cam in patent document 3. The control rod of the present invention corresponds to the drive rod of patent document 2.

Fig. 4 shows an operation immediately before the operation of the stitch suppressing grooves 40a of the stitch suppressing plate 40 is activated in the glove knitting machine 1 of fig. 1. The coil suppressing plate 40 has a coil suppressing groove 40a in the vicinity of the front edge on the tooth gap 2 side. The coil suppression groove 40a is closed on the left side of the drawing, which is the other side in the longitudinal direction, and opens to the mouthpiece 2 side while extending to the right side, which is one side. The stitch suppressing plate 40 is movable in the longitudinal direction, overlaps the roots of the adjacent knitted finger pockets 51 and 52 (only the section is simply indicated by the reference numeral) and is disposed at the bottom of the needle body 42 of the knitting needle 41 arranged in the longitudinal direction on the needle bed gap 2 side. Each knitting needle 41 is formed by connecting a needle jack (japanese: 1247212515\1248363) 43 to the rear end of a needle body 42 having a hook 42a at the front end thereof. A needle bed heel (japanese: \1249612483\12488) 42b of the needle body 42 projects toward the carriage 3F side in the vicinity of the coupling portion. Although not shown, the rear portion of the jack 43 is connected to the selector cylinder, and swings with the connecting portion as a fulcrum in accordance with the result of needle selection. The bed side butt 43b projecting from the needle jack 43 toward the carriage 3F side is raised and lowered in accordance with the needle selection result. The trajectories of the tip end portion of the needle body 42 for operation, the needle bed side butt 42b, and the needle bed side butt 43b of the knitting needle 41 accompanying the leftward movement of the carriage 3F are shown.

The stitch suppression plate 40 is not used for the first knitting of the finger pocket 51, but is used for the next knitting of the finger pocket 52. The knitting of the finger bag using the stitch suppressing plate 40 is performed by moving the stitch suppressing plate 40 to the right. The stitch suppressing groove 40a is used so that stitches to be the finger base portions 51a on the finger pocket 52 side to be knitted next enter the finger pocket 51 to be knitted first, in a state of being locked to the hooks 42a. Before the stitch suppressing groove 40a is activated in this manner, the stitch cam 16 is operated, and the knitting needle 41 in which the stitch of the finger base portion 51a is engaged with the hook 42a is drawn in from the driving cam surface 16b to the needle bed side. In example 1, the drawing amount of the knitting needle 41 by driving the triangular face 16b can also be adjusted so as to facilitate the penetration into the stitch suppressing groove 40a.

Fig. 5 shows an example of

finger bags

51, 52, 53, 54, 55 and a glove 50 produced by knitting with the glove knitting machine 1 of fig. 1. As shown in fig. 5 (a), the stitch suppressing groove 40a functions from the left side of the finger pocket 51 knitted first, and holds the stitch of the finger base portion 51a on the needle bar of the knitting needle 41 while the adjacent finger pocket 52 is knitted next. The finger pocket 52 shown by the two-dot chain line is knitted by using the knitting needle 41 staying on the needle bar and the knitting needle 41 on the left side thereof, starting from the fingertip 52f and repeating the knitting of the body portion 52t as shown by the solid line, and the base portion 51a of the finger pocket 51 is knitted. As shown in fig. 5 (b), glove 50 is formed with finger pockets 51, 52, 53, 54, 55 having finger bases 51a, 52a, 53a, 54a superimposed on one another. The glove 50 is knitted by knitting a little finger pocket 51 to an index finger pocket 54 in this order, then knitting a four-finger body, and further knitting a thumb pocket 55. The same finger root overlapping can be performed not only between the

pockets

51 and 52 but also between the other finger pockets or between the four fingers and the finger pocket 55. The three-finger body may be knitted by knitting the ring finger pocket 52 to the index finger pocket 54 first, and the four-finger body may be knitted by knitting the little finger pocket 51. In order to change the direction in which the formed finger bases overlap, the coil suppressing plate 40 in which the direction in which the coil suppressing groove 40a opens is changed may be used, and the direction in which the coil suppressing plate acts may be changed.

Fig. 6 shows the structure of the main part of the glove knitting machine 1 of fig. 1. The rear needle bed paired with the front needle bed 4F is disposed at a position symmetrical with respect to the virtual center plane 2a, but not shown. The glove 50 is formed in a tubular shape by alternately using the front and rear needle beds. In the following description, only the front needle bed 4F is described, but the same applies to the rear needle bed. The knitting needle 41 is accommodated in a needle groove provided in the needle bed 4F, and is driven so that the hook 42a advances and retreats toward the needle bed gap 2.

The needle bed 4F has a sinker bed 45 at the top on the needle bed gap 2 side. The sinker bed 45 accommodates movable sinkers 46. The movable sinker 46 is arranged in a row in the longitudinal direction, is disposed between the knitting needles 41, is driven by a sinker cam 47 provided in the carriage 3F or 3B, and has a tip end that advances and retreats toward the needle bed gap 2. The movable sinker 46 has a loop forming portion 46a at the front edge on the needle bed gap 2 side, on which a sinker loop is caught during stitch formation, and a knitted fabric pushing-down portion 46b at the lower side, which pushes down the knitted fabric between the knitting needles 41 below the needle bed gap 2. The movable sinker 46 is driven as follows: when the coil is formed, the tip is advanced into the notch 2, and after the coil is formed, the tip is once retreated from the notch 2, and the tip is advanced into the notch 2 again to push down the coil. The movable sinker 46 is driven for knitting needles 41 in a range wider than the range in which the needle is selected to knit the finger pocket 52. For example, in the stitches of the finger pocket 51 knitted first in fig. 5 (a), the stitches in the section to the right of the finger base portion 51a are repeatedly subjected to the push-down by the advance and retreat of the movable sinker 46. These stitches are easily affected by the push-down by the movable sinker 46 when the hooks 42a are pulled in from the needle bed gap 2 to form stitches and the knitting yarn is locked in a state where the knitting yarn is tensed. The multiple push-down by the movable sinker 46 tends to move the knitting yarn, and the loops of the stitch are narrowed to extend the sinker loop, and as described above, there is a possibility that the appearance and the texture are different from those of other stitches not subjected to the multiple push-down. The return cam surface 16a of the needle presser 16 acts on the needle butt 42b on the needle bed gap side to return the knitting needle 41 for locking the stitches of the finger pocket 51 to the needle bed gap 2 side. At the time of knitting the finger pocket 52, the section of the finger pocket 51 excluding the finger base 51a is not needle-selected, and the needle bed gap side butt 52b is also acted to return to the triangular surface 16a even in the case of non-needle-selection. Returning the knitting needle 41 in this manner loosens the stitches to relax the tension of the knitting yarn, and even if the knitting yarn is repeatedly pushed down, the knitting yarn becomes in a state of being hard to move, and it is difficult to generate stripes having different appearances and different hand feelings of the stitches in the course direction. However, if the knitting needle 41 excessively returns, there is a possibility that a miss occurs in which the stitch in the hook 42a drops off from the hook 42a, and therefore the operation position of the return is adjusted so that the miss does not occur. If the knitting needle 41 is maintained at the return position, the operation of returning the knitting needle 41 by the needle presser 16 may be performed only once in the first course of the knitting finger pocket 52, and in the subsequent courses, the return cam face 16a may be set to a non-operating state so as not to act on the butt 42b on the needle bed edge side.

Fig. 7 shows the operation after knitting the finger pocket 52 while activating the stitch suppressing groove 40a in the glove knitting machine 1 of fig. 1, with the trajectories of the tip portion of the needle body 42, the needle bed side butt 42b, and the needle bed side butt 43 b. For example, in the example of fig. 5 (a), when knitting of the finger pocket 52 is completed, the stitch suppressing plate 40 is moved leftward until the stitch suppressing groove 40a is separated from the finger base portion 51a and the finger pocket 52. The movement of the stitch suppressing plate 40 is performed in a state where the knitting needle 41 of the stitch at the locking finger base portion 51a is returned to the needle bed gap 2 side. The returned position is set to the stitch size reference position 41a or a position close thereto when shown with the front end position of the hook 42a of the knitting needle 41. The stitch size value is set in accordance with the drawing amount of the knitting needle 41 by the knitting cam 14, and when the stitch size value becomes large, the stitch becomes large. The coil size reference position 41a is a position at which the coil size value becomes 0. Further, the upper limit of the return position is limited by the abutment of the needle butt 42b with the lower edge of the needle cam 17. By moving the stitch suppressing plate 40 leftward, the stitch held at the base 51a of the needle bar of the knitting needle 41 is released from being suppressed, and moves toward the needle bed gap 2 along the inclination of the opening of the stitch suppressing groove 40a. By returning the knitting needle 41 to the state before the movement of the stitch suppressing plate 40, the resistance received by the stitch at the finger base portion 51a when the needle bar of the knitting needle 41 is moved toward the needle bed gap 2 is reduced. The reduction in resistance makes it easy for the coil to return to the tooth mouth 2 side without biting when the coil moves along the inclined portion of the coil inhibiting plate 40. Since only the knitting needle 41 is returned, the stitches of the finger-base portion 51a stay on the needle bar without being dropped, but can be reliably dropped in the next knitting operation. However, when the returned position is not appropriate, there is a possibility that a miss may occur in which the stitch of the finger base portion 51a is detached from the hook 42a due to the momentum released from the stitch restraining groove 40a. The returning position needs to be adjusted according to the characteristics of the knitting yarn and the like.

In embodiment 1, the amount of return in the case where the stitch cam 16 is used as a return cam can be adjusted from the outside by an adjusting unit including the control rod 31 and the rod mechanism 20. Since the knitting needle 41 is returned to the needle bed gap 2 side by the needle presser 16 using the needle bed gap side butt 42b, the needle selection can be performed regardless of the needle selection result, and the needle selection can be performed in the same course following the course of the knitting finger pocket 52. The amount of return may be adjusted so that the amount of return differs between the case where the finger bag 52 is knitted while the stitch suppressing groove 40a is activated as shown in fig. 5 and the case where the function of the stitch suppressing groove 40a is terminated as shown in fig. 7. The adjustment means may be constituted only inside the carriage 3F by mounting a stepping motor or the like on the carriage 3F. Even when the gloves 50 can be mass-produced with the temporarily adjusted return amount, the return amount can be manually adjusted at the time of stopping the carriage 3F by switching only the function of the stitch cam 16 by the control bar. For example, the switching by the lever mechanism 20 may be performed in advance until the return amount reaches the maximum, and the means for adjusting the return amount may be provided with a stopper stopped by a screw or the like.

Example 2

Fig. 8 shows an operation after knitting the finger bag 52 while activating the stitch restraining groove 40a in the glove knitting machine 61 according to example 2 of the present invention. In example 2, a cam including a stitch cam 64 and a stitch cam 66 is mounted on a cam plate 60F. The stitch cam 64 is provided with a return cam surface 64a on the needle bed gap 2 side, and functions also as a return cam for returning the knitting needle 41, which holds the stitch of the finger base portion 51a on the needle bar, to a return position such as the stitch size reference position 41a by the action of the butt 42b on the needle bed gap side. The knitting cam 64 draws in the knitting needle 41 so that the inclined driving cam surface 64b acts on the bed butt 43b, and is guided by the inclined groove 64c so that the drawing corresponds to the stitch size. Since the knitting needle 41 is returned to the needle bed gap 2 side by using the needle bed gap side butt 42b, it can be performed regardless of the needle selection result, but since the stitch cam 64 is used, it is performed by providing another course after the knitting of the finger pocket 52. In example 2, as shown in fig. 5 of example 1, the knitting needle 41 can be returned so as to be less affected by the push-down by the movable sinker 46. The knitting of the finger bag 52 may be performed by providing a different course from the knitting of the finger bag 52 before or during the knitting of the finger bag 52. Just before the stitch suppressing plate 40 is activated, the stitch cam 66 is activated only to draw the knitting needle 41 to the needle bed side by the driving cam surface 66b, and therefore, similarly to patent document 3, the operation and the non-operation may be switched by moving the guide groove 66c in the vertical direction by switching driving from the outside.

According to the present embodiment 2, the return cam surface 64a is provided to the stitch cam 64, and the stitch cam 64 draws in the knitting needle 41 to the needle bed side so that the stitch having a size corresponding to the stitch size value is formed by the drive cam surface 64b acting on the butt 43b on the needle bed side. The return triangular surface 64a can be driven so that after knitting of the finger pocket 52 in which the stitch suppressing groove 40a is made to function, the stitch at the finger base portion 51a of the finger pocket 51 knitted earlier is stopped by the knitting needle 41 of the needle bar, and the knitting needle 41 in the section to the right of the finger base portion 51a during knitting of the finger pocket 52 is returned to the needle bed gap 2 side. The returning amount of the knitting needle 41 can be adjusted to an appropriate amount by a mechanism for adjusting the stitch size similar to patent document 2.

Example 3

Fig. 9 shows an operation after knitting the finger bag 52 while activating the stitch restraining groove 40a in the glove knitting machine 71 according to example 3 of the present invention. A cam including the stitch cam 74 and the stitch cam 66 is mounted on the cam plate 70F. The stitch cam 74 also functions as a return cam that acts on the bed side butt 43b to return the knitting needle 41 to the needle bed gap 2 side, with a receiver facing the lower end of the inclined drive cam surface 74b serving as a return cam surface 74 a. This action can be performed in the same manner as in example 2 so that the effect of the push-down by the movable sinker 46 is less likely to be exerted before or during the knitting of the finger bag 52 after the operation of the stitch inhibiting plate 40. In example 3, the needle bed side butt 43b of the returning knitting needle 41 is set to the needle selecting state shown by the solid line, and is performed in a stitch course different from the stitch knitting of the pocket 52.

In embodiment 2 and embodiment 3, the

stitch cams

64 and 74 are driven by a motor or the like provided outside the carriage 3F via a lever mechanism or the like, similarly to the components related to the control rod 31 in fig. 2. The adjustment of the return amount can be performed along with a mechanism provided for adjusting the coil size.

Since the respective embodiments can adjust the returning amount of the knitting needle 41, the adjusting means can adjust the returning amount of the knitting needle 41 before the knitting of the finger pocket 52 is started or during the knitting with the function of the stitch suppressing groove 40a, and immediately before the movement of the stitch suppressing plate 40 after the knitting. Adjustment of the return amount enables reliable doffing and improves the quality of the glove 50.

Further, although the adjustment of the return amount in each embodiment is performed from the outside of the carriages 3F and 3B by the control rod 31, a motor or an actuator may be mounted inside the carriages 3F and 3B. Even if the return amount can be adjusted by external adjustment, the space and weight of the carriages 3F and 3B can be prevented from increasing.
