Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glove knitting machine that knits a glove with a finger pouch into a tubular knitted fabric and has a stitch restraining plate for performing crotch overlap between the finger pouches.

2. Description of the Related Art Conventionally, a glove knitting machine that forms a glove or the like by sequentially knitting finger pouches while performing crotch overlap has a pair of front and rear needle beds, and a belt-like stitch restraining plate is provided at the tip of the needle bed on the needle bed side. It has (for example, see patent document 1). In Patent Document 1, the stitch holding plate corresponds to the stitch restraining plate. The needle bed has needle plates arranged at a constant pitch along the longitudinal direction. Knitting needles are housed in needle grooves between needle plates and arranged in the longitudinal direction of the needle bed, and the hooks at the tips of the knitting needles are advanced and retracted into the needle gap to knit the knitted fabric. The advance and retreat of the knitting needle is driven by a cam mounted on a carriage that reciprocates along the longitudinal direction of the needle bed.

The cams mounted on the carriage include stitch cams used for knitting stitches and pressure cams used when a stitch restraining plate is operated. The stitch cam acts to pull the knitting needle, which has received the knitting yarn supplied to the hook at the needle bed, to the needle bed side when the stitch is formed. The retraction amount by the stitch cam corresponds to the stitch value representing the size of the stitch. In order to reduce the weight of the carriage, stitch adjustment in a glove knitting machine is performed by driving a stitch cam from outside the carriage via a control bar (see, for example, Patent Document 2). The degree of action of the cams other than the stitch cams used for stitch formation is also adjusted by driving via a control bar from the outside of the carriage (see, for example, Patent Document 3). Patent Document 3 introduces a pressure cam as one of movable cams that can be switched between active and inactive via a control bar.

The stitch deterrent plate has a stitch deterrent groove extending in the longitudinal direction and opening to one side at a position away from the tip of the needle bed side toward the needle bed side. The stitch restraining groove having such a shape is used for knitting the finger stall adjacent to the previously knitted finger stall on the other longitudinal side while performing the crotch overlap. When the stitch restraining plate is moved from the other side in the longitudinal direction with respect to the knitting needles holding the stitches in the toe part of the previously knitted finger stall to allow the stitches in the toe part to enter the stitch restraining groove, Knockover is suppressed by fixing the stitch to the needle stem directly above the stitch suppression groove. When the pressure cam is actuated, it acts on the knitting needle that holds the stitch of the crotch portion to the hook, pulls the knitting needle toward the needle bed, and makes it easier for the stitch to enter the stitch restraint groove. A portion of the knitting needle closer to the needle bed side than the stitch restraint groove is used for knitting the crotch portion of the adjacent finger stall. When the knitting of the next finger stall is completed, the stitch restraining plate is moved to the other side in the longitudinal direction, and the stitch restraining groove is separated from the stitches of the crotch portion to the other side. The stitches of the crotch portion of the previously knitted finger stall return to the cuff side through the inclined portion of the stitch restraining plate, and overlap the stitches of the crotch portion of the next finger stall knitted on the crotch side. When knitting the knitted fabric of the body portion following the two finger stalls, the stitches of the two finger crotch portions are knocked over as double stitches to form a crotch-overlapped crotch portion.

Japanese Patent No. 3053376 JP 2008-007916 A JP 2013-044077 A

In recent years, glove knitting machines are required to knit thin gloves such as coating gloves and gloves for precision work using fine knitting yarns. However, when the knitting yarn becomes thin, problems tend to occur when the stitch restraining plate is pulled out from the crotch portion and the stitch held by the stitch restraining groove is returned along the inclined portion toward the needle bed side. A thin knitting yarn is easily caught and caught in a gap for sliding between the upper surface of the stitch restraining 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 previously knitted stitches of the toe part of the finger stall is not released continues. The stitches are pulled as the knitting of the knitted fabric of the trunk progresses, and then released and knocked over. Knitted fabric products with such knockover delays are of poor quality.

The needle plate is a plurality of plate-like members arranged side by side on the substrate of the needle bed to form the needle bed. Knitting needles are a plurality of needle-like members that are housed in needle grooves between needle plates and move forward and backward with respect to the needle bed gap. Since these members must slide between each other, they cannot be brought into close contact with each other, resulting in gaps in which fine knitting yarns are caught. In Patent Document 1, the end surface of the portion corresponding to the inclined portion of the stitch deterrent groove is formed as an inclined surface so that even a thin knitting yarn is less likely to be caught in the gap between the upper surface of the stitch deterrent plate and the bottom surface of a needle plate or the like. there is However, it is difficult to prevent fine knitting yarns from being caught in the shape of the stitch restraint groove.

In order to ensure the knockover, it is necessary to pull the knitted fabric downward. However, since the glove knitting machine knits out the finger stalls sequentially from the fingertips, it is not possible to use a pull-down device that pulls down the entire knitted fabric including the finger stalls. For this reason, the glove knitting machine uses a movable sinker that functions as a sinker when forming stitches and that has the function of pushing down the knitted fabric between knitting needles. However, when knitting the subsequent finger stall, the carriage also enters the section of the knitting needle that knits the previous finger stall, and the sinker cam drives the movable sinker. Therefore, while knitting the succeeding finger stall, the sinker loop between the knitting needles, which locks the needle loop of the stitch of the previously knitted finger stall on the hook, is in a state of tension when the stitch is formed, and the movable sinker It is pushed down multiple times due to repeated advance and retreat. When the stitches including these sinker loops are pressed down multiple times by the movable sinker, they become streaks in the direction of the course that differ in appearance and texture from other stitches that are not pressed down, impairing the quality of the glove to be formed. problems can arise.

SUMMARY OF THE INVENTION An object of the present invention is to provide a glove knitting machine capable of improving the quality of gloves knitted while performing crotch overlap between finger pouches by the action of a stitch restraining plate.

1 to 7 relate to the configuration and operation of a glove knitting machine 1 that is Embodiment 1 of the present invention. 8 and 9 relate to the operation of the second and third embodiments of the present invention. Corresponding parts in each figure are denoted by the same reference numerals, and redundant description may be omitted. Also, for convenience of explanation, parts not shown in the drawings to be explained may be referred to by attaching reference numerals shown in other drawings.

FIG. 1 shows cam arrangement of a glove knitting machine 1 that is Embodiment 1 of the present invention. A glove knitting machine 1 is provided with a pair of needle beds that are opposed to each other with a needle gap 2 therebetween and arranged at symmetrical positions with respect to a virtual center plane 2a. However, FIG. 1 omits illustration of the needle beds. The front and rear needle beds are provided with carriages 3F and 3B that reciprocate in the longitudinal direction, respectively. The longitudinal direction of the needle bed corresponds to the lateral direction in the figure. Carriages 3F and 3B respectively have cam plates 10F and 10B facing the surface of the needle bed. A cam plate 10F of the carriage 3F on the front needle bed is mounted with a gun cam 11, a rubber cam 12, a middle cam 13, a stitch cam 14, a needle raising cam 15, a pressure cam 16, a needle guide cam 17 and a top cam. The cam 18 is mounted on the cam plates 10F, 10B of the front and rear carriages 3F, 3B. These cams are similar to those described in US Pat.

The pressure cam 16 of Embodiment 1 is provided with a return cam surface 16a and a drive cam surface 16b. to return to the tooth gap 2 side. The pressure cam 16, like the pressure cam of Patent Document 3, functions to pull the knitting needle toward the needle bed with a drive cam surface 16b provided on the needle bed side at the operating position indicated by the dashed line. This function is used to make it easier for the stitch restraining plate to act on the knitting needles that hold the stitches of the toe part of the previously knitted finger stall on the hooks. The adjusting means, which will be described later, drives the pressure cam 16 so as to move vertically in the drawing, and switches functions by moving between two operating positions, and switches between adjustment of each operating position and non-operating in the middle. can be done.

2 and 3 show the configuration and operation of the main parts inside the carriage 3F used in the glove knitting machine 1 of FIG. The carriage 3B of FIG. 1 is also basically equivalent. 2 shows a state in which the return cam surface 16a is used to make the pressure cam 16 function as a return cam, and FIG. 3 shows a state in which the drive cam surface 16b is used. The movement of the pressure cam 16 is performed along the vertical guide groove 16c. The driving of the pressure cam 16 and the switching of functions are performed via a lever mechanism 20 mounted on the carriage 3F. Lever mechanism 20 includes lever 21 , slider 22 , spring 23 and roller bearing 24 . The lever 21 has two arms, and the tip of one arm engages the slider 22 and is pulled by the spring 23 . The slider 22 moves up and down along the guide groove 16c. The roller bearing 24 is attached to the tip of the other arm of the lever 21 and can be replaced with a spherical or arcuate member. A guide shaft 25 shown in (b) guides movement of the carriage 3F in the longitudinal direction of the needle bed.

The guide member 30 is installed in the vicinity of the traveling path of the carriage 3F so as to extend in the longitudinal direction, and supports the control bars 31, 32, 33, 34 extending in the longitudinal direction so as to be displaceable in the vertical direction in the figure. Roller bearings 24 are biased by springs 23 so as to press against the side edges of one control bar 31 . Vertical displacement of the control bar 31 angularly displaces the lever 21 and displaces the slider 22 vertically. The slider 22 is connected with the pressure cam 16 . The lever mechanism 20 drives the pressure cam 16 according to the amount of displacement of the control bar 31 . By driving the control bar 31 by mounting a stepping motor or the like on a driving device provided at the end in the longitudinal direction, the operating state of the pressure cam 16 is switched and at least the return amount as the return cam is adjusted. Such control bar 31 and lever mechanism 20 constitute the adjusting means of the present invention. The adjustment by the adjustment means can be performed by driving a motor or the like provided outside the carriage 3F, like the stitch cam stitch adjustment in Patent Document 2 and the operation of the movable cam in Patent Document 3. Note that the control bar of the present invention corresponds to the drive bar of Patent Document 2.

FIG. 4 shows the operation of the glove knitting machine 1 of FIG. 1 immediately before the stitch restraining groove 40a of the stitch restraining plate 40 is activated. The stitch restraining plate 40 has a stitch restraining groove 40a near the front edge on the needle bed 2 side. The stitch restraint groove 40a closes on the left side in the figure, which is the other side in the longitudinal direction, and opens toward the needle bed gap 2 side while extending in the right direction, which is the one side. The stitch restraining plate 40 is movable in the longitudinal direction, and is used for performing crotch overlap between adjacently knitted finger bags 51 and 52 (only the sections are indicated by reference numerals for simplification), and is arranged in the longitudinal direction. is disposed on the bottom portion of the needle body 42 on the needle bed 2 side of the knitting needle 41 provided in the . Each knitting needle 41 is formed by connecting a jack 43 to the rear end of a needle body 42 having a hook 42a at the tip. A mouth side butt 42b of the needle body 42 protrudes toward the carriage 3F near the connecting portion. Although not shown, the rear portion of the jack 43 is connected to a needle selection drum, and swings about the connecting portion according to the needle selection result. A needle bed butt 43b projecting from the jack 43 toward the carriage 3F appears and disappears according to the needle selection result. The movement of the knitting needle 41 as the carriage 3F travels to the left is indicated by the trajectories of the tip portion of the needle body 42, the needle bed side butt 42b, and the needle bed side butt 43b.

The stitch restraining plate 40 is not used for knitting the first finger stall 51, but is used from the next finger stall 52 knitting. The knitting of the finger stall using the stitch suppression plate 40 is performed by moving the stitch suppression plate 40 rightward. The stitch deterrent groove 40a is used so that the stitches forming the finger crotch portion 51a on the side of the finger stall 52 to be knitted next from the previously knitted finger stall 51 enter while being held by the hook 42a. Before the stitch restraint groove 40a is activated in this manner, the knitting needle 41 that holds the stitch of the interfinger portion 51a on the hook 42a is retracted to the needle bed side by the drive cam surface 16b by operating the pressure cam 16. . In Embodiment 1, the retraction amount of the knitting needle 41 on the drive cam surface 16b can also be adjusted so that it can easily enter the stitch restraint groove 40a.

FIG. 5 shows an example of finger bags 51, 52, 53, 54, 55 knitted by the glove knitting machine 1 of FIG. As shown in FIG. 5(a), the stitch restraint groove 40a is operated from the left side of the previously knitted finger stall 51, and the stitches of the finger crotch portion 51a are formed while the adjacent finger stall 52 is being knitted. It is fastened to the needle stem of the knitting needle 41 . The finger pouch 52 indicated by the two-dot chain line uses the knitting needle 41 for fixing the toe part 51a of the finger pouch 51 to the needle stem and the knitting needle 41 on the left side thereof, and is knitted from the fingertip 52f as indicated by the solid line, and then the body portion 52t. Knitting is repeated. As shown in FIG. 5(b), the glove 50 is formed in a state in which the crotch portions 51a, 52a, 53a, 54a are overlapped between the finger pouches 51, 52, 53, 54, 55. As shown in FIG. The glove 50 is formed by sequentially knitting a finger bag 51 for the little finger to a finger bag 54 for the index finger, knitting a four-legged body, and further knitting a finger bag 55 for the thumb. A similar crotch overlap can be performed not only between the finger bags 51 and 52 but also between other finger bags or between the four-legged body and the finger bag 55 . It is also possible to knit a finger bag 52 for the ring finger to a finger bag 54 for the index finger first to knit a three-pin trunk, and further knit a finger bag 51 for the little finger to knit a four-pin trunk. In order to change the direction of the crotch overlap to be formed, a stitch restraining plate 40 having a different opening direction of the stitch restraining groove 40a may be used, and the acting direction may be changed.

FIG. 6 shows the configuration of the main parts of the glove knitting machine 1 of FIG. The rear needle bed paired with the front needle bed 4F is arranged symmetrically with respect to the imaginary center plane 2a, but is not shown. The glove 50 is formed into a tubular shape by alternately using front and rear needle beds. Although only the front needle bed 4F will be described below, 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 such that the hook 42a advances and retreats from the needle bed 2. As shown in FIG.

The needle bed 4F has a sinker bed 45 on the upper part of the needle bed 2 side. A sinker floor 45 accommodates a movable sinker 46 . The movable sinkers 46 are aligned in the longitudinal direction, are arranged between the knitting needles 41, and are driven by sinker cams 47 provided on the carriages 3F and 3B so that their tips advance and retreat from the needle bed 2. As shown in FIG. At the tip of the movable sinker 46, a loop forming portion 46a to which a sinker loop is applied during stitch formation is positioned at the leading edge on the needle bed 2 side, and a knitted fabric push-down portion 46b for pushing the knitted fabric downward between the knitting needles 41 is positioned below the needle bed 2. have on the side. The movable sinker 46 is driven so as to enter the tip into the needle bed 2 when forming the stitch, temporarily withdraw the tip from the needle bed 2 after the stitch is formed, and enter the tip again into the needle bed 2 to push down the stitch. . The driving of the movable sinker 46 is performed for the knitting needles 41 in a wider range than the needle-selected section for knitting the finger pouch 52 . For example, among the stitches of the finger stall 51 knitted earlier in FIG. If the hook 42a is pulled into the needle bed 4F from the needle bed 2 to form the stitch and the knitting yarn is held in a taut state, these stitches are likely to be affected by the push-down by the movable sinker 46. Multiple depressions by the movable sinker 46 make it easier to move the knitting yarn so that the needle loop of the stitch shrinks and the sinker loop extends, and as described above, other stitches that are not subjected to multiple depressions There is a possibility that the appearance and texture will be different from The return cam surface 16a of the pressure cam 16 acts on the needle mouth side butt 42b to return the knitting needle 41 that holds the stitches of the finger stall 51 to the needle mouth 2 side. When the toe bag 52 is knitted, needles are not selected in the section of the toe bag 51 excluding the crotch portion 51a. Returning the knitting needles 41 in this way loosens the stitches to relax the tension of the knitting yarn, makes it difficult for the knitting yarns to move even if the pressing down is repeated, and makes the streaks with different appearances and textures of the stitches appear in the course direction. make it difficult for However, if the knitting needle 41 is returned too much, the stitch in the hook 42a may come out of the hook 42a, resulting in a dropped stitch. If the knitting needle 41 is maintained at the returned position, the operation of returning the knitting needle 41 by the pressure cam 16 is performed only once in the first course for knitting the finger bag 52, and in the subsequent courses the return cam surface 16a is returned to the needle gap. It may be in a non-actuated state so as not to act on the side butt 42b.

FIG. 7 shows the operation of the glove knitting machine 1 of FIG. 1 after the finger bag 52 is knitted while the stitch restraining groove 40a is applied to the tip portion of the needle main body 42, the needle bed side butt 42b, and the needle bed side butt 43b. Shown by the trajectory. For example, when the knitting of the finger stall 52 is completed in the example of FIG. The movement of the stitch restraining plate 40 is performed in a state in which the knitting needle 41 that holds the stitch of the crotch portion 51a is returned to the needle bed gap 2 side. The return position is the stitch reference position 41a or a position close to it when indicated by the tip position of the hook 42a of the knitting needle 41 . The stitch value is set corresponding to the retraction amount of the knitting needle 41 by the stitch cam 14, and the larger the stitch value, the larger the stitch. The density reference position 41a is a position where the density value is zero. The upper limit of the return position is regulated by the contact of the mouth-side butt 42b with the lower edge of the needle guide cam 17. As shown in FIG. By moving the stitch restraining plate 40 to the left, the restraint of the stitches of the finger crotch portion 51a, which has been in front of the needle stem of the knitting needle 41, is released, and the opening of the stitch restraining groove 40a is released. along the slope of the tooth gap 2 side. By returning the knitting needle 41 to the state before the movement of the stitch restraining plate 40, the stitch of the crotch portion 51a reduces the resistance received when the needle stem of the knitting needle 41 moves toward the needle gap 2 side. The reduction in resistance makes it easier for the stitches to return to the needle bed 2 side without being caught when the stitches move along the inclined portion of the stitch restraint plate 40 . Since the knitting needle 41 is simply returned, the stitch of the crotch portion 51a remains on the needle stem without being knocked over, but can be reliably knocked over in the next knitting operation. However, if the returning position is inappropriate, there is a possibility that the stitches of the crotch portion 51a will be released from the stitch restraining grooves 40a, causing the stitches to separate from the hooks 42a. The return position needs to be adjusted according to the characteristics of the knitting yarn.

In the first embodiment, the amount of return when the pressure cam 16 is used as the return cam can be adjusted from the outside via adjusting means including the control bar 31 and the lever mechanism 20 . Returning the knitting needle 41 to the needle bed 2 side by the pressure cam 16 is performed using the tooth bed side butt 42b, so it can be performed regardless of the needle selection result, and the finger bag 52 can be knitted following the course of knitting. Can be done in the same course. The return amount should be adjusted differently depending on whether the finger stall 52 is knitted while the stitch restraining groove 40a is working as shown in FIG. 5 or when the action of the stitch restraining groove 40a is finished as shown in FIG. can also The adjusting means may be configured only inside the carriage 3F by mounting a stepping motor or the like on the carriage 3F. If the glove 50 can be mass-produced with the return amount once adjusted, only the function of the pressure cam 16 is switched via the control bar, and the return amount is adjusted manually while the carriage 3F is at rest. You can also For example, switching by the lever mechanism 20 is allowed until the return amount reaches the maximum, and the return amount adjustment means may be provided with a stopper that is stopped by a screw or the like.

FIG. 8 shows the operation after the finger stall 52 is knitted by the glove knitting machine 61, which is the second embodiment of the present invention, while the stitch restraining groove 40a is operated. In the second embodiment, a cam including a stitch cam 64 and a pressure cam 66 is mounted on the cam plate 60F. The stitch cam 64 is provided with a return cam surface 64a on the side of the needle bed 2, and acts on the needle bed side butt 42b to return the knitting needle 41, which holds the stitch of the finger crotch portion 51a to the needle stem, to the stitch reference position 41a or the like. It also functions as a return cam to return to the position. The stitch cam 64 retracts the knitting needle 41 so that the inclined driving cam surface 64b acts on the needle bed side butt 43b, and is guided by the inclined groove 64c so that the retraction is performed according to the stitch value. Returning the knitting needle 41 to the needle bed 2 side is performed using the needle bed side butt 42b, so it can be done regardless of the needle selection result. After the knitting, another course is provided. In the second embodiment as well, it is possible to return the knitting needle 41 so as not to be affected by the depression by the movable sinker 46 as shown in FIG. 5 of the first embodiment. A course separate from the knitting of the finger stall 52 may be provided before or during the knitting of the finger stall 52 . Since the pressure cam 66 acts only to pull the knitting needle 41 toward the needle bed side with the drive cam surface 66b immediately before the stitch restraining plate 40 acts, similar to Patent Document 3, the switching drive from the outside causes vertical movement. It suffices to move along the guide groove 66c and switch between operation and non-operation.

According to the second embodiment, the return cam surface 64a pulls the knitting needle 41 toward the needle bed side so that a stitch having a size corresponding to the stitch value is formed by the drive cam surface 64b acting on the needle bed side butt 43b. Provided on the stitch cam 64 . The return cam surface 64a is formed by the knitting needles 41 that hold the stitches of the between-toe part 51a of the previously knitted finger pouch 51 to the needle stem after knitting the finger pouch 52 by acting the stitch restraining groove 40a, and the knitting of the finger pouch 52. The knitting needle 41 in the section on the right side of the crotch portion 51a can be driven so as to return to the needle gap 2 side. The return amount of the knitting needle 41 can be adjusted appropriately using the same stitch adjustment mechanism as in Patent Document 2.

FIG. 9 shows the operation after the finger stall 52 is knitted by the glove knitting machine 71, which is the third embodiment of the present invention, while the stitch restraining groove 40a is operated. A cam including a stitch cam 74 and a pressure cam 66 is mounted on the cam plate 70F. The stitch cam 74 also acts as a return cam to return the knitting needle 41 to the needle bed side 2 by acting on the needle bed side butt 43b with a return cam surface 74a that faces the lower end of the inclined drive cam surface 74b. . As in the second embodiment, this action may be performed after the stitch restraining plate 40 is activated, before or during the knitting of the finger stall 52, in order to reduce the influence of the push-down by the movable sinker 46. can. In the present embodiment 3, the needle bed side butt 43b of the returning knitting needle 41 is in the needle selection state as indicated by the solid line, and the stitches of the finger pouch 52 are knitted in a different course.
