Description

{FLATBED KNITTING MACHINE}

The present invention relates to a knitting machine which is provided with a needle bed facing forward and backward and knitting a glove or a sock into a tubular shape while selecting a knitting needle as a needle drum provided on each needle bed, To a flat knitting machine.

Conventionally, in order to knit a work knitting glove having fingers respectively holding five fingers or a sock having a toe portion, a glove knitting machine for knitting a tubular flat knitted fabric or a knitting machine for a sock knitting machine is used have. In these flat knitting machines, knitting cams are driven by knitting cams mounted on carriages which are provided with front and rear opposite needle beds and which reciprocate in the longitudinal direction of the needle beds. For example, the forward direction is set in the knitting cam such as the front needle bed for the movement of the carriage in the left direction and the back needle bed for the movement in the right direction, and the needle beds are used alternately. The knitting needles used in the knitting in the forward direction are selected by the needling drums provided in the respective needle beds. In the reverse direction, even the selected knitting needle does not receive the action of the knitting cam. The driving of the carry and the needle bed drums is performed by a common driving source, and the front and back throat drums rotate together. The applicant of the present application has proposed a flat knitting machine capable of utilizing a human force as a common driving source (see Patent Document 1).

An annular groove in the circumferential direction is formed corresponding to each knitting needle of the needle bed on the outer periphery of the needle bar drum, and the notch groove in the axial direction divides each annular groove into a plurality of stages. The needle pins of each step are attached to or detached from the notch grooves at positions corresponding to the respective knitting needles by attaching or detaching a needle pin for a needle or by attaching and detaching a needle pin having a length corresponding to a section of a plurality of needles continuous in the knitting width direction, (See, for example, FIG. 5 and FIG. 6 of Patent Document 2). In each of the annular grooves, a control jack for controlling the appearance of a butt formed on the tail portion of the knitting needle is slid. The needle stop pattern is reflected through the control jack in the protruding and retracting of the butt of the knitting needle with respect to the needle groove, and selects whether or not the button is driven by the knitting cam. The throat drum intermittently turns to one side when the carriage repeatedly reciprocates to advance the knitting. There has been proposed a glove knitting method in which a driving source for rotationally driving front and rear needle rollers is provided so as to be capable of being driven independently of other parts (for example, see Patent Document 3). However, the front and rear needle rollers rotate together.

6 shows the shape of the glove knitted with the glove knitting machine in a simplified manner. The four fingers 1, 2, 3 and 4 are sequentially knitted from the base to the index finger, the four finger palm 5 is knitted, and the finger 6 of the thumb is knitted And the five-pointed body 7 is knitted.

Fig. 7 shows an example of a stencil pattern in which the irregularities set by the stencil fin are expanded in the circumferential direction on the stencil drum used for knitting the gloves of Fig. 6. With this needle patting pattern, a glove with a standard four-finger body design in which a front stitch of a plain stitch appears on the surface is knitted. 8 is a turn glove, which shows a gloved needle touch pattern of a specification that is supposed to be used after being knitted after being knitted. In order to coat the rubber or the like with the surface of the back needle bed in the back needle bed as shown in Fig. 8 (a), the fingers 1, 2, 3, 4 ) Is slightly different from that of Fig. 9 is an open finger, which shows a gloved finger touch pattern in which the fingers 1, 2, 3, 4 and 6 are opened so that the fingertips are exposed when mounted . (A) is a rear needle bed, and (b) is a front needle pattern of the front needle bed, (a) is a front needle bed, (B), the step proceeds from the upper side to the lower side. A rod-shaped long needle pin is inserted in a portion continuous in the lateral direction at each end. In such a portion, a knitted fabric of plain stitch is knitted.

7, Fig. 8, and Fig. 9 can be knitted by changing the movement range of the carriage in common. However, the touch patterns from the finger portions 1, 2, 3, 4 to the four-finger body 5, the thumb portion 6, and the five-finger body 7 must be prepared separately. For example, the stencil pattern of the finger 1 shown in Fig. 7A has a knitting start portion 1a, a taper portion 1b, a tubular portion 1c, and a longitudinal end portion 1d. The number of knitting courses increases in the tubular portion 1c.

It is difficult to replace the predetermined stitch pattern once set because the stitch pin is firmly mounted to prevent the stitch pin from falling off. It is also possible to use needle-shaped needle pins in a section which is knitted continuously in the knitting width direction in the knitting start portion 1a, the taper portion 1b, and the cylindrical portion 1c when the needle needle pattern is first set If it is assumed, it is necessary to prepare several long pins. It is troublesome to arrange a plurality of needle pins for one needle as used in the terminal end 1d.

The timing for advancing the end of the predetermined drum in order to change the stitch pattern with respect to one needle bed is set so as not to affect even if the preceding stitch drum rotates together and a waiting time for such timing is required, . In addition, since the front and back throat drums run together, there is a case where the stage is advanced even though there is no need to change the stitch pattern. In such a case, as in the last two stages of the tubular portion 1c, the successive next stages are also set to the stencil pattern of the same length. As a result, the required number of stages of the entire throttling pattern increases, and the number of required throttling pins increases.

It is an object of the present invention to provide a weft knitting machine in which it is not necessary to set the same needle length pattern at a plurality of consecutive steps of the needle selection drum and there is no need to wait for timing to rotate the needle selection drum so that knitting efficiency is lowered .

The present invention relates to an image forming apparatus which is provided with a needle bed facing forward and backward and which is provided with a needle pattern which is set on the outer periphery of a needle selection drum provided on each needle bed BACKGROUND OF THE INVENTION 1.

A schematic configuration of a main portion of a weft knitting machine 10 used in the first and second embodiments of the present invention will be described below with reference to Figs. 1 and 2. Fig. For convenience of explanation, parts not described in the drawings to be explained may be referred to by attaching the reference numerals in other drawings. 3 shows a stitch pattern (needle pattern) 30 used in the first embodiment of the present invention. Fig. 4 shows the stencil pattern 40 used in the second embodiment of the present invention. Fig. 5 shows an example of gloves that can be knitted with the stencil pattern 40 of Fig.

The flat knitting machine 10 shown in Fig. 1 has a front needle bed 11 and a back needle bed 12. The front needle bed 11 and the back needle bed 12 are opposed to each other with a needle bed gap 13 interposed therebetween. Knitting needles 14 are provided on the front needle bed 11 and the back needle bed 12 so that the tips of the hooks advance and retract into the needle bed gap 13 to knit the knitted fabric . The knitting needle 14 is accommodated in a needle groove formed in a direction perpendicular to the paper surface of the drawing. Further, the knitting needle 14 only shows the back needle bed 12 side, and the front needle bed 11 side is omitted. The basal end side of the knitting needle 14 is connected to a needle jack 15. The needle jack 15 is provided with a control butt 16 for driving the knitting needle 14 to move back and forth with respect to the needle bed gap 13. When the control butt 16 protrudes from the needle groove in the rising direction, the needle is in the needle-tight state. This needle selection state is controlled by the needle selection jack 17. The needle selection jack (17) is provided with a predetermined needle convex portion (18). The control button 16 in the needle-holding state is subjected to the action of a knitting cam mounted on the carriage 20. The carriage 20 is moved so as to reciprocate in the direction perpendicular to the paper surface, with the needle grooves in the front needle bed 11 and the back needle bed 12 facing the surface formed in parallel. The knitting needle 14 and the needle jack 15 may be integrally formed.

The front needle bed 11 and the rear needle bed 12 are provided with needle needles 21 and 22, respectively. Each knitting needle 14 is selected by the stencil pattern set on the outer periphery of the stencil drums 21, 22.

The flat knitting machine 10 is provided with drive mechanisms 23 and 24 capable of individually driving each of the pre-setting drums 21 and 22, knitting data of a predetermined knitting fabric, And a control means 25 such as a controller for controlling the drive mechanisms 23 and 24 so as to angularly displace each of the pre-finishing drums 21 and 22 based on the data. The drive mechanisms 23 and 24 shown in the drawings respectively include motors provided respectively to the predetermined-timing drums 21 and 22 and serving as drive sources for rotationally driving through intermeshed gears. The rotation driving force may be transmitted by directly connecting the motor to each of the front needle rollers 21 and 22 or through a belt and a pulley. Each of the needle selection drums 21 and 22 can be driven or stopped so as to be angularly displaced respectively in forward and reverse directions that are one of the circumferential direction and the other direction. The drive mechanisms 23 and 24 may include a clutch so that the motor serving as the drive source may be shared. Notch grooves 26 extending in the axial direction perpendicular to the paper surface are formed in the preferential drums 21 and 22 so as to be parallel to each other at a constant pitch in the circumferential direction. The annular groove in the circumferential direction is formed to be parallel to the axial direction at a constant pitch corresponding to the needle groove. The leading end of the predetermined convex portion 18 in the pick-and-jack 17 is fitted in an annular groove. The needle pin 27 can be attached to or detached from the notch groove 26. One of the notch grooves 26 is enlarged to be a drawing groove 28. [

Fig. 2 shows the difference in the staple state of the knitting needle 14 by the staple drum 22 in Fig. The same stitching is also performed by the stitch drum 21 of Fig. 2 (a) shows a state in which the leading end of the predetermined convex portion 18 is in contact with the needlepoint 27 mounted on the notch groove 26. As shown in Fig. The leading edge of the predetermined convex portion 18 floats from the bottom of the annular groove so that the control butt 16 also floats from the needle groove and the needle 14 is in the needle-tight state.

2 (b) shows a state in which the leading end of the predetermined convex portion 18 is accommodated in the draw groove 28 formed in the preferential drum 22. The predetermined convex portion 18 can be detached from the annular groove in the axial direction at the portion of the draw groove 28. This makes it possible to perform maintenance such as change of the stitch pattern by pulling out the needle bar 22 in the axial direction have. According to the present invention, it is not necessary to set the stencil pattern of the same length at a plurality of consecutive stages of the stencil drum 22, so that the drawing groove 28 can be formed.

2 (c) shows a state in which the leading end of the predetermined convex portion 18 is fitted in the notch groove 26 of the predetermined drum 22. The distal end of the predetermined needle convex portion 18 sinks into the annular groove at the portion where the needle pin 27 is not attached to the notch groove 26 and the control butt 16 also enters the needle groove It is in a sinking state.

Examples 1 and 2 below describe the case of knitting gloves of various specifications, but it is also possible to knit socks of plural specifications in the same manner by preparing the needle-like pattern for socks.

(Example 1)

Fig. 3 shows the stencil pattern 30 used in the first embodiment of the present invention. Fig. 3 (a) is set in the throat drum 22, and Fig. 3 (b) is set in the throat drum 21, respectively. Using the finger portions 31, 32, 33, and 34, the four finger palm 35, the thumb finger portion 36, and the five-finger body 37 of the stitch pattern 30, , The glove can be knitted in the direction of the thumb from the base as in the case of using the stencil pattern shown in Figs. 8 and 9, respectively. 3 (a) includes a knitting start portion 31a, a tapered portion 31b and a terminating portion 31c, and a portion corresponding to the tubular portion 1c is omitted . In addition, the knitting start portion 31a is used to start knitting the gloves of the open finger specification of Fig. 9, and the knitting start portion 1a of the finger portion 1 of Fig. 7 (a) And a portion of the final stage is used in the portion 31b. In this case, the front needle drum 22 is angularly displaced in the reverse direction after the start of knitting, skipping the middle step and shifting to the first stage of the tapered part 31b, So that the knitting of the finger 31 is continued. The four-pointed body 35 and the five-pointed body 37 are used for knitting a plurality of courses in one step. In this way, it is possible to knit gloves having the four-pillar body specification as shown in Fig. Since such a glove with a four-finger body specification is produced by a conventional glove knitting machine, it is shown as a standard glove in order to distinguish it from a turn glove specification or an open finger specification. The terminating portion 31c is not used when knitting a glove of a turn glove specification. As described above, the stitch pattern 30 can include gloves of three specifications: a standard specification as a four-pillar body, a turn glove specification, and an open finger specification. It is easy to reduce the number of specifications without including the parts used only for a specific specification.

(Example 2)

Fig. 4 (a) and Fig. 4 (b) show the stencil pattern 40 used in the stencil drums 22 and 21 according to the second embodiment of the present invention. Fig. 5 shows an example of gloves that can be knitted with the stencil pattern 40 of Fig. The stencil pattern 40 includes finger portions 41, 42 and 43 from the finger to the forefinger, a trunk body 44, a finger portion 45 of the base, a four-finger body 46, And the five-pointed trunk 48, respectively. A knitting start portion 49 for using the knitting needles at positions not used at the front end is added to the second stage following the five-pillar body 48 by using the knitting needles one by one. The gloves of the tricepic body specification shown in Fig. 5 (a) or the gloves of the four-pillar body specification shown in Fig. 5 (b) can be knitted by using or not selectively overlapping the stencil pattern 40. [ Further, for example, if the end portion 41c of the finger 41 is not used, gloves that are the specification of the three-finger body and the four-finger body but are the specification of the turn glove can also be knitted individually. In other words, the stencil pattern 40 may include both gloves of a four-pillar body specification and a three-pillar body specification. For example, if the three-pillar body 44 is not formed, it is possible to reduce the number of specifications so that the three-pillar body specification is excluded.

When knitting is started using the knitting start portion 49, the knitting pattern of the five-pillar body 48 is successively used to knit an arm cover as a cylindrical knitted fabric having a constant diameter It is possible. In the stitch pattern such as the knitting start portion 49 or the knitting start portion 31a in Fig. 3A, for example, a miss and a knit are repeated in each course, and in the next course It is also possible to use interlock knitting in which the knitting of the previous course is knitted and the knitting of the entire course is made to correspond to the miss. Also, a miss pattern in which a stitch in a course is missed can be knitted by setting another stitch pattern on successive stages. Such an interlock knitting or a miss pattern can be knitted into all or a part of a knitting width even in an arm cover, a four-pillar body, a five-pillar body, etc., and is not limited to various specifications of gloves, Can be used. The interlocking knitting or the miss pattern and the like need to be changed in each glove knitting machine or the like for setting the needle-touching pattern on the needle drum only in the conventional one-way direction, so that the required number of steps is increased and the needle can not be accommodated in the needle drum. By applying the present invention, various knitted fabrics can be knitted by effectively using the pre-setting drum.

As described above, in the first and second embodiments, the front needle bed 11 and the front needle beds 12, 22 of the back needle bed 12 can be angularly displaced independently from each other, There is no need to wait for the time to become. In addition, a plurality of specifications can be mixed in the stencil pattern by angular displacement, including skipping in the direction of the forward and reverse directions or the end. Thus, knitted fabrics of a plurality of specifications can be knitted without changing the pre-set drums 21, 22 or changing the stitch pattern.

Even when the driving mechanisms 23 and 24 use a common motor as the driving source and can be angularly displaced only in the normal direction in the forward and backward directions independently of each other by the clutch, The front needle drum 22 of the rear needle bed 12 as the other needle bed is angularly displaced and the next needle cloth pattern is prepared while the front needle drum 11 of the front needle bed 11 is stopped by cutting off the clutch good. It is not necessary to interlock the needle rollers 21, 22 of both needle beds and to set the needle-like needle pattern of the same length at a plurality of stages necessary for not decreasing the knitting efficiency. However, it is presupposed that the weft knitting machine 10 is provided with a stitch restraining rod, a looper, or the like that corresponds to the specification to be knitted.
