Description

Apparatus for controlling links-links jacquard forming circular knitting machine}

The present invention relates to a control device of a double-head shaping circular knitting machine, and more specifically, it is possible to freely control the density of the fabric while freely forming various types of patterns by expressing the yin and yang by both heads, and the body plate and rubber end are integrated. It relates to a control device of a double-head molded circular knitting machine for controlling the operation of the double-headed circular knitting machine for producing a seamless cylindrical fabric at the same time the finished molded article is knitted one by one.

In general, knitting machines can be divided into flat knitting machines and circular knitting machines. Conventional flat knitting machines mainly focus on production of fabrics, and in knitting sweaters, when finishing the sleeve ends or the rubber ends of the body plates, In contrast, it adopts a ribbed knitting structure with good elasticity and two body structures before and after. That is, since it was a flat plate structure having a general form of fabric, the weight of labor cost such as sewing process was very high in order to manufacture it as a garment. And, such a conventional flat knitting machine had a problem of very low productivity.

In order to solve the problems of the conventional flat knitting machine, a circular knitting machine in which the cylinder and the cam are continuously rotated at high speed has been proposed, but such a general circular knitting machine could not form a pattern on the fabric by the negative and positive, and the body plate and the rubber end Since there is no separate device for inserting a span yarn, the span yarn insertion knitting becomes impossible.

An object of the present invention is to freely control the density of the fabric while forming a variety of patterns in the expression of yin and yang by the two heads, the finished molded article integral body and rubber ends are knitted one by one and at the same time seamless cylindrical The present invention provides a control device for a double-headed circular knitting machine for controlling the operation of a double-headed circular knitting machine for producing a fabric.

Various knitting such as a punch car is made by the control device of the double-head molded circular knitting machine according to the present invention configured as described above, the density (smooth) is adjusted, and the operations such as knitting of a general yarn and finishing knitting of a spanner can be controlled. Can be.

The specific flow of operation will be described with reference to FIG.

First, the diskette in which the knitting file is stored in the FDD 72 is inserted (S2), and when the power is supplied, the circular knitting machine performs an initialization operation by itself. That is, the actuator 80 grasps the position of the initial double-headed needle 42 (S4). When the initialization is finished, the user selects a file for the desired work (S6) to run (run) the machine.

At this time, when the recognized position of the first two needles 42 comes to the position of the first actuator (80) (S8) knitting to form a pattern is started (S10). As the pattern is formed, pulses for operation of each double needle 42 are supplied from the encoder 78 (S12), and knitting is performed to satisfy a predetermined pattern as shown in FIGS. 5, 8, and 9 (S14). ). When the knitting operation is performed according to the flow stored in the file, if the knitting is made by a predetermined length, the rubber end is knitted while being supplied through the spanner feeder 20 by air pressure for finishing as necessary (S16).

When one knitting operation is made, it is determined whether to continue the same work according to the input number, and when there is no further work or when the fabric needs to be withdrawn, the fabric is withdrawn through the fabric withdrawal unit 3. .

Referring to FIGS. 5, 8, and 9, a process of knitting is added, and a plurality of cams are provided at predetermined intervals on the inner circumferential surface of the central cam box 8 so that a guide path having a predetermined shape between these cams ( 60 is formed and the butts of the jacks (52, 46, 48) and the slide is guided along the guide path (60).

In addition, the two needles 42 are moved up and down while hanging the thread 11 while being moved up and down among the cams installed on the inner circumferential surface of the central cam box 8, and the length of the nose by the flow cams 38a and 38b. Is adjusted.

The lower cam 40 is disposed at the lower end of the central cam box 8 to itself constitute a cam to form a guide path 60, so that the butt 54f of the cylinder jack 48 is guided.

The one-way cylinder 16 is installed on the outer circumferential surface of the upper cam box 7, a plurality of two-stage auxiliary jack by blocking the guide path 60 formed horizontally of the upper cam box 7 through the guides (58a, 58b). Butts 54a and 54b of 52 are guided downwardly along inclined guideway 60 while simultaneously pushing down both duplex needles 42 so that the duplex needles 42 can be threaded in the next step. In addition, by opening the horizontally formed guide path 60 of the upper cam box (7) so that the butts (54a, 54b) of the two-stage auxiliary jack 52 is moved horizontally along the guide path (60) formed on the horizontal line. At the same time, both needles 42 are prevented from weaving. The operation proceeds while rotating in each step of the two needles 42, the position is sensed by the encoder 78, a knitting pattern is formed to match the position.

As shown in FIG. 8, the slide press 24a installed in the upper cam box 7 moves the double needles 42 upwards, and as a result, the lower head of the double needles 42 can thread the center cam box. The slide press 24b installed at (8) moves both the needles 42 downward, and in the next step, the actuator 62 is operated to push the guide protrusion 54f of the cylinder jack 48, thereby causing both needles ( The upper head of the double-headed needle 42 is able to weave thread during the horizontal movement of 42).

The stepping motors 12, 14, and 86 are flow cams 38a of the upper cam box 7 and the center cam box 8 so that the double needles 42 supplied with the thread from the apostle 26 flow up and down a predetermined length. , 38b), and the two needles woven with the thread 42 flows upwards or downwards, as shown in FIG. 9, in order to finally determine the density of the fabric by adjusting the nose length of the yarn to be short and long. .

As described above, according to the control device of the double-head shaping circular knitting machine according to the present invention, in addition to forming a double-headed pattern in which yin and yang are formed when knitting the body plate, a skip (punch car) distinguished from the double-headed pattern, a finishing operation by a spanner This is achieved, there is an advantage that can be produced by the appropriate control of the drive of the stepping motor to the annular fabric in which the density (the figure) is freely adjusted.

Therefore, according to the present invention, it is possible to freely form various types of patterns in the expression of yin and yang by the two heads, to freely control the density of the fabric, and to knit the finished molded article in which the body plate and the rubber end are integrated. have.

And, there is an effect that can produce a seamless cylindrical fabric.

Although the present invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that various modifications and variations are possible within the technical scope of the present invention, and such modifications and modifications are within the scope of the appended claims.
