Loop knitting machine of circular knitting machine {CUTTING DEVICE FOR LOOP FORMATION ON THE RING-TYPE KNITTING MACHINE}

The present invention relates to a loop knitting device of a circular knitting machine. In particular, a pair of up and down lifting selection cams which are assembled adjacent to a single cam plate having the same structure in a continuous order of 1, 2, 2, 3, 3, 1- It is possible to install various kinds of tissues according to the arrangement method of these cam groups. Moreover, it is possible to make 30% high-density knitting by reducing the easy needle to one space, and also to prevent the yarn from shining on the floor. The present invention relates to a loop knitting device of a circular knitting machine having added value and a knitting method thereof.

In general, the conventional circular knitting machine, along with the upper cam plate for mounting the cams of various structures suitable for guiding the desired needle needle groups on the cylinder main wall surface of the circular knitting machine, and installs the lower cam plate constituting the control group so that they can be selectively operated In order to continuously knit the loops knitted according to the combined cam structure of the upper and lower cam plates, a disk-shaped loop presser plate (also called envan) is provided at the intersection of the lower cam plates.

However, such a conventional circular knitting machine is not only very cumbersome to replace, such as changing the entire cam arrangement of the cam plate or replacing it with a new cam plate every time the tissue is changed, but also requires a huge manufacturing cost to process the cams. Even though it was very rare to use a campan, it had to be produced anew, so a very uneconomical problem was pointed out.

In addition, the circular knitting machine uses a loop presser plate positioned at the intersection of the upper and lower cam plates as well as the operation and replacement of the cam plate to cut the knitted loops to form a pile, and the upper and lower knitting needles sufficiently press the knitted loops due to the intersection. In this state, the loop is cut as a cutter, which is obliquely cut because the loop is pushed to one side, and the end of the loop pressed by the pressing plate is also severely damaged after cutting. There are various problems, such as not good.

Therefore, the present inventors can change the lifting cam position of the lower cam plate which is arranged on the outer wall of the cylinder of the circular knitting machine in order to solve such a conventional problem, and select various tissue forms without mechanical change or cam modification through relatively simple cam movement. There have been proposed loop loop knitting apparatuses of circular knitting machines having an improved structure, which can be knitted in the same manner, and they are introduced in detail in Korean Utility Model Publication Nos. 94-8279, 96-8822 and Patent Registration Publication 0286515.

The seamen's draft is operated by matching the cam group arrangement of the lower cam plate by adjusting the lifting cam position of the upper cam plate, so that the pile can be piled due to the loop knitting density and thread tension even when the disk-shaped pressing plate is removed. Providing high-quality pile fabric with no damage to the end, it is possible to reduce the weight of the device and pursue the convenience of operation. Furthermore, the length of the loop cut surface can be kept uniform even without the secondary processing. It is preferably used to provide a good quality pile fabric at a low price.

However, such a source draft also found a phenomenon that it is never easy to maintain the density of the tissue tightly, resulting in an imbalance of the woven fabric tissue.

That is, the number of cam groups constituting the upper cam plate is unified in two, and the order of supply of the needles guided to them is the same in order of 1,1-2,2-1,1-2,2- It is configured to be repeatedly supplied twice, and it improves workability, and it is possible to produce high-quality pile fabrics that are not damaged by the loop knitting density and thread tension even when the disk-shaped pressing plate is removed. Although the pile fabrics can be provided, it is pointed out that the pile fabric has a relatively wide gap between loops, and thus, the density of the fabric tissue is greatly decreased, thereby causing non-settling of yarns in the flat tissue constituting the floor. It was becoming.

The present invention was devised to overcome these problems, and continuously arranges the lifting selection cams assembled in pairs in a unit combination of 1, 2, 2, 3, 3, 1-, and adjusted therein. By supplying a plurality of knitting needles with different heights of the bat in sequence, the loop needle of the high value added circular knitting machine, which allows 30% of high-density knitting to be made by reducing the number of needles passing through each cam plate to one space. The main purpose is to provide a cutting device.

Another object of the present invention, while maintaining the density while using the same weight of yarn, the pile yarn is always firmly fixed by the adjacent knitted structure, through which the non-settling phenomenon of the pile yarn on the bottom surface, while the bottom To reduce the elasticity of the cotton to provide a looping knitting and cutting device of excellent circular knitting machine that does not require a separate resin (pool) feed.

The loop knitting and cutting device of the present invention is applied to a loop knitting device having two or more cam groups different from each other so that the knitting needles 10 and 20 can be selectively guided and arranged on the cylinder circumferential wall of the circular knitting machine. do.

The loop growth piece of the present invention is provided with a lifting fixing cam 31 at the bottom so that the knitting needles 10 having the common batt 11 can be guided sequentially and simultaneously, and on one side thereof, a plurality of lowering guide cams. The upper cam plate 30 of 1st, 2nd, and 3rd of the same shape is arrange | positioned one by one along the cylinder circumferential wall of the sieve circular knitting machine provided with (32).

One side of the lowering guide cam 32 of the first, second, and third upper cam plates 30 also has a, b, c, having adjustment batters 12a, 12b, 12c of varying heights. Vertical grooves so that the three needles 10 are guided successively so that only the needles 10 having adjustment batters 12a, 12b and 12c which protrude to the same height among these needles 10 can be selectively guided. (2) between the first, second and third upper cam plate (30) arranged in a series of combinations to install assembling a two-stage lifting selection cam (35) paired at a selected height along the (33) In addition, a single needle horizontal guide cam plate 37 is provided regularly.

In addition, the lower cam plate 40, which is configured to combine the guide cam group 41 in the order corresponding to the arrangement position of the elevating selection cam 35, is installed at the lower portion of the lower cam plate 40. Cutter guide cams 42 are regularly disposed between the two, and the cutter guide cams 42 of the lower cam plate 40 are provided on the single needle horizontal guide cam plate 37 regularly provided between the upper cam plate 30. ) Is configured to correspond 1: 1 to each other and is provided with a plurality of parallel guide cams 38 so that the deflection or shaking of the knitting needle 10 can be regulated when cutting the loop by the cutter 21.

In other words, the apparatus of the present invention is suitable for knitting various loop structures in a conventional circular knitting machine each having an upper cam plate 30 provided on a cylinder circumferential wall and a lower cam plate 40 provided on an upper side thereof. The structure of the upper and lower cam plate 30, 40 arranged in the form of a single unit, but only the fixed portion to guide the common needles 10, 20 in a predetermined passage and the needles 10, 20 to move selectively It consists of a movable part for changing the position so that it can be guided and fixed, so that three or more identical cam plates 30 having different positions in two stages in succession are provided in a series of combination orders. By simply arranging accordingly, it is possible to mass-produce various and excellent types of loops.

In other words, the upper and lower lifting fixing cam 31 is provided to guide the common batt 11 of the knitting needle 10 to raise all the knitting needles 10 at the same time, and the elevated knitting needles 10 at the upper portion thereof. A plurality of descending guide cams 32 are provided for guiding downwards, and the lifting select cams 35 are mounted adjacent to the side of the lowering guide cams 32, and the lifting select cams 35 are vertical grooves 33 of the cam plate. The first, second, and third upper cam plate 30 is configured to be installed at a selected position among the fixing holes drilled along), while the first, second, and third arranged in a combined form. Between the upper cam plate of the 30 is installed a single guide horizontal guide cam plate 37 consisting of a plurality of parallel guide cams 38 to maintain a regular interval, the upper cam plate 30 is the lifting selection cam ( Only one row is selectively positioned at positions corresponding to the parallel guide cams 38 of the horizontal guide cam plate 35 and the horizontal guide cam plate 37, respectively. In addition to the guide cam group 41 of the combination type that is opened by the cutter guide cams 42 are arranged to protrude more forward than the guide cam group 41 so as to draw out the cutter 21 at the position to cut By having the lower cam plate 40, it is possible to express various kinds of desired tissues without disassembling or replacing the cam plate through relatively easy position change of the elevating selection cam 35.

Figure 2 is a preferred embodiment of the present invention three cam groups showing a two-stage 1,2-2, 3-3, 1-assembling form a pair according to the fixed position of the lower guide cam 32 in the upper portion It consists of a set, and the lower part shows the arrangement | positioning structure of the flat knitting machine which respectively provided these cam groups and the corresponding guide cam group.

According to the present invention configured as described above, first, after the three types of first, second and third upper cam plates 30 having the same shape as shown in the order are arranged in order, Taking into consideration the shape of the tissue (2, 3, 4, 5), the lifting selection cam 35 of the upper cam plate 30 is selectively fitted to the fixing hole on the vertical groove 33 of the upper cam plate. Assemble Then, the guide cam group 41 of the lower cam plate 40 is arranged correspondingly. The cam plates 30 and 40 have three types of a, b, and c, each of which has a common batt 11 at the lower end and an adjusting batt 12a, 12b, 12c at different heights. The guide will be guided in turn (10).

As such, the knitting needles 10 supplied to the tips of the first, second, and third upper cam plates 30 reach the lower end of the knitting needles 10 when they reach the position of the elevating selection cam 35 of the upper cam plate 30. The common batt 11 protruding is temporarily lifted upward by the elevating fixing cam 31 and the lowering guide cam 32, and then a pair fixed to positions 1 and 2 of the initial cam plate installed at the position A of FIG. In order to reach the elevating selection cam 35, the adjustment batt 12a of the a single needle 10 and the adjustment batt 12b of the b needle 10 are successively raised, and the first guide cam group of the lower cam plate 40 ( 41, the lower knitting needles 20 a and b being guided along each other are formed.

At this time, the guide cam group 41 of the lower cam plate 40 constitutes a predetermined number of rows (Y1, Y2, ...) according to the number of combinations of the knitting needles 20, the guides installed at the first position (A) Cam group 41 is in a state in which only the third row Y3 is opened, and the remaining rows Y1, Y2, and Y4 are shown in a closed state using a cover plate, so only the adjustment batt 22c of the c knitting needle 20 is selectively selected. I can guide you.

In other words, the upper a and b knitting needles 10 passing through the pair of lifting selecting cams 35 fixed at positions 1 and 2 in the first cam plate A pass through the threads, respectively, and thus the loop is knitted. This is not done, but the c knitting needle 10 passing therethrough is to pass through the empty needle, so as to meet with the c knitting needle 20 when passing through the guide cam group 41 of the lower cam plate 40, one loop is formed. It will be organized.

The a, b knitting needles 10 and 20 pass through the upper and lower cam plates 30 and 40 installed at the position A of FIG. While passing through the A position of the upper and lower cam plates (30) and (40), bite pile yarn and form a loop, and reach the B position, a pair of elevating selection cams (35) fixed at Nos. 2 and 3 and While only the upper and lower b and c knitting needles 10 through which the adjusting batt 12b and 12c are guided along the guide cam group 41, the flat tissue and the c knitting needle 20 are raised to form a loop, When the C position is reached, only the upper and lower a and c knitting needles 10 to which the adjustment batt 12a and 12c are guided along the elevating selection cam 35 and the guide cam group 41 fixed at Nos. While the flat tissue and b piece needle 20 will rise to form a loop.

After the predetermined basic structure is completed in this way, the three needles pass through a needle guide horizontal guide cam plate 37 consisting of a plurality of guide cams 38 parallel to each other. (10) Since the upper and lower flow is shown to be sufficiently suppressed while passing the flat needle horizontal guide cam plate 37, the lower knitting needles 20 having the cutter 21 at the tip reaches the D position and the cutter induction cam 42 When passing the more advanced than when passing through the guide cam group 41, A, B or C position of the lower needle 20, the loop by the cutter 21 will be able to cut naturally.

When cutting the loop, it is possible to construct a high-quality loop of the sieve that does not put a strain on the looping tissue to be organized only when the loop is sufficiently extended, and for this purpose, a disk-shaped loop press plate is often used, but in the present invention As described above, the third knitting on the same cam plate is repeated, and as weaving the looping tissues, the loops knitted to cross each other, as shown in FIG. The loop will have the effect of being fully pressed by the remaining loops. Due to the removal of the pressure plate, the tension is loosened, so that the closed end such as loosening the loop or having different heights of the loops can be effectively prevented.

FIG. 3 schematically illustrates the loop knitting order of the present invention according to a knitting needle arrangement procedure. First, the upper and lower cam plates 30 and 40 are along the elevating selection cam 35 and the guide cam group 41. , b, c After the three upper knitting needles 10 and the lower knitting needles 20 are continuously supplied and the corresponding loops are knitted by them, the pre-cutting of the corresponding loops previously formed for the next loop formation as the cutter 21 is performed. And then knitting the needles in the cut position again according to the procedure, repeating the repeated knitting process of cutting the remaining loops and then successively knitting the cut loops, thereby forming a pile of high value added piles of dense density. do. In the embodiment of the figure illustrates a case where the loops are repeatedly formed in the order of 3-1-2-3-using a cam plate arranged in the form of 1,2-2,3-3,1-1,2- It is shown as an enemy.

After the loops are knitted in three knitting positions according to a predetermined order as described above, the loops formed at the front are cut and then the corresponding loops are newly knit. The loops cut by the cutter 21 are previously knitted loops. Since it is depressed with sufficient tension, the unbalanced organization and the loosening of the loops never occur. 4 exemplarily illustrates the loop formation and the loop cutting correlation of the present invention.

In other words, according to the present invention, since the forced loop fixing is not performed, such as using a pressure plate to cut the loop, the length of the loop can be provided uniformly, and the end of the loop is severely damaged by the pressure plate. Therefore, the side effects such as poor hair loss will also have the advantage that can be effectively suppressed.

According to the above, as a preferred embodiment of the present invention, the pair of upper and lower cam plates 30 and 40 having the same structure according to the arrangement position of the knitting needles 10 and 20 only the fixed position of the elevating selection cam 35. Embodiments that can be configured in various ways have been shown. However, the present invention is not limited to the above embodiment.

As another embodiment of the present invention, the objectives of the present invention can be effectively achieved by arranging the upper cam plate and the lower cam plate in a different position as applied in the prior art. This embodiment also has the same overall configuration and effect as in the above embodiment, but there is only a difference to the extent that it can be preferably operated even if it is not provided with a common bat at the bottom of the upper knitting needle.
