Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a purl knitting machine having four mutually arranged needle beds and a carriage carrying a cam for actuating all the needles, in which the needle beds are The double-ended needle is located in a plane intersecting the needle, and there is also a double-ended needle and a silk-fitting jack for moving the needle.

Known purl knitting machines of this type (U.S. Pat. No. 1,797
No. 436), the double-ended needle is whisker-shaped.

For the purpose of pressing the needle heads, it is necessary to provide a presser plate that occupies a considerable amount of space in the area where the knitting operation takes place, and the production of uniform and simple patterned items requires complicated control of the presser plates combined with various needles. The disadvantage is that it requires specialized equipment. The present invention was made in view of the above-mentioned drawbacks, and by eliminating the need for a presser plate and a complicated device for controlling it, which were conventionally required, it is possible to create a double-ended lingual needle using a cam, which is simpler than conventionally. The purpose of the present invention is to provide a purl knitting machine that is operated to perform pattern knitting.

The purpose is to use a double-ended tongue needle as a double-ended needle, and to provide a green stitch transfer plate on the needle bed at least on the far side from the silk separation position where each knitted stitch is detached from the tongue needle and a new stitch is subsequently formed. This can be achieved by

A type of Perl machine is known (German Patent Specification No. 70 237) having two oppositely arranged needle beds arranged in one and the same plane.

The double-ended needles used in these machines are formed as double-ended lingual needles, and a transfer plate is provided on each needle bed. However, whereas in these machines the transfer plate has the sole purpose of carrying out the hanging between adjacent needles to create a handle, the transfer plate according to the invention is also provided for producing circular products, and the transfer plate according to the invention In the green machine, the double-ended needles are moved into opposing needle beds, so that the bran is moved from the center of the needle into the already closed hook with the aid of a transfer plate. The transfer plate for this purpose will be specifically called a stitch transfer plate. The details of the present invention will be explained below with reference to the accompanying drawings.

Referring to an example of the type of purl knitting machine according to the invention shown in FIG. .1,
N. B. 2,N. B. 3,N. B. 4).
Needle beds 1 and 2 are arranged in one plane, and needle bed 3
The needle rest 4 is arranged in another plane intersecting the plane.

Needle beds 1 and 2 and needle beds 3 and 4 constitute two sets of needle beds of a flat plate or pearl striped machine, and needle beds 1 and 3 are combined to form a pair of needle beds of a pair of parallel V-shaped bed line machines. form. Needle bed 1
and 2 are matched with needle 9 and needle beds 3 and 4 are fitted with needle 1
0, these needles form the basic component.
The lower needle beds 1 and 3 are equipped with jacks 5 and 11, and the upper needle beds 2 and 4 are equipped with jacks 6 and 12, and also with stitch transfer plates 7 and 13.
The purl knitting machine according to the invention can be compared to a knitting machine that combines two green machines, which is particularly capable of producing cross-bed annular cross green products. An example of a pattern that can be knitted is described below. In conjunction with FIGS. 1 to 5, FIGS. 6a to 6f show the mode of operation of the double-ended lingual needle when producing the ridges of a circular product of R/R knitting (rechG-techb: rubber knitting). express.

When making this type of stitch, the two stitches 8 and 14 of the knitted fabric are first placed on needle beds 1 (N.B. 1) and 3 as shown in FIG. (N
．． B. Each of needles 9 and 10 in 3) accepts one stitch. The carriage shown as 17 in FIG. 8 is placed, for example, on the right side of the page in FIG. 6a, and the needle bed 4 is moved from FIG. 1 to FIG. It has been pre-retracted into the position shown.
The carriage is then moved from right to left in the figure as indicated by the horizontal arrow in Figure 6b.

At this time, among the needles 9 of the needle bed 1, the odd numbered hands 1, 3, 5, etc. are moved from the needle bed 1 to the needle bed 2 in the usual manner by jacks 5 and 6 and a cam (not shown). FIG. 2 shows the positions to which these hands 9 have moved. At the same time, the even-numbered needles 9, such as No. 2, 4, 6, etc., in the needle bed 1 are pushed out beyond the loop forming distance and are pushed out of the needle bed 1 again.
drawn inside. 3 and 4 during these needle movements.
The stitches 15 and 16 are inserted into the needle 9 at a particular point so that stitches 15 and 16 are formed on both needle beds as shown. FIG. 6b shows the needle 9 moved to the needle bed 2 and the row of stitches knitted by the needle beds 1 and 2. The loop formation in the needle bed 2 is shown in FIG. 2, and the loop formation in the needle bed 1 is shown in FIG. As shown, it is arranged adjacent to the left or right hand groove of the needle 9 in each case in FIGS. 1, 2, 4 and 5. While the carriage moves from right to left in the drawing, the needle 9 is again pulled out of the needle bed 2 and returned into the needle bed 1, and the stripe transfer plate 7 is removed from the needle as shown in FIG. The deviated stitch 15 is accepted.

Here, the stitch 15 is passed through the needle 9 again by further advancing the stitch transfer plate 7. This stage is shown in FIG. The needles are brought into alignment by the cam before the jack leaves them.

All the needles are then placed on the needle bed 1 along with their bran. As shown in FIG.
It can be hung from the needle 9 of etc. The carriage occupies the left-hand position on the page of the figure.

The needle bed 2 is retracted and the needle bed 4 is brought into its basic position. The carriage is then moved from left to right on the page of the figure. At this time, needle 10, jacks 11 and 12, and butts 13 of needle beds 3 and 4 operate in the same manner as described above for needle beds 1 and 2. 6d and 6e
The figure is a diagram of the corresponding needles and side stitches of needle beds 3 and 4. Finally, Figure 6f shows the path taken by the threads in the needle beds 1 and 3 and shows the face of the rubber bran circular knit after the carriage cycle or stroke is completed.

FIG. 7 shows how the double-ended tongue needle is operated when creating ridges in a circular knitted fabric of purl wire.

As shown in FIGS. 1 and 7a, two loops 8 and 14 of the knitted fabric are knitted on needles 9 and 10 of needle beds 1 and 3. The needle bed 4 has been retracted. Needles 9 and 1
Each 0 carries the 1st green. The carriage is located, for example, at the right hand position on the page of the figure. Now move the carriage to the left on the paper.

During this movement, all needles 9 are guided from needle bed 1 to needle bed 2. During the movement of these needles, the thread is applied to the needle 9 and a row of face stitches is loosened on the needle bed 2, as shown in detail in FIGS. 2 and 7b. During the same movement of the carriage, all needles 9 are moved from needle bed 2 to needle bed 1, and still a second row of bran grains is knitted by a second thread insertion, in this case as shown in FIG. 7c. It is knitted on the needle bed 1 as shown. The needle bed 4 is then brought into its basic position and the needle bed 2 is retracted, so that the carriage is moved from left to right in the plane of the drawing.

When this operation is performed, the needle 10 is guided from the needle bed 3 into the needle bed 4. During the movement of these needles, the thread is applied to the left-hand needle 10' in the corresponding position and still one row of stitches is formed on the needle bed 4 as shown in FIG. 7d. During the same movement of the carriage, all the needles 10 are drawn back into the needle bed 3 again and a second row of stripes is formed by a second thread insertion, as shown in FIG. 7e. FIG. 7f schematically shows the green eye after the completion of the first knitting cycle, in which case the back eye is observed from the outside.

On the other hand, FIG. 7g is a schematic diagram of the stitches after the completion of the second knitting cycle, and in this case, the front stitches are observed from the outside. A patternless or plain purl knitted fabric can be obtained by constant alternation of the back stitch and front stitch of the stitch row. Although not shown, a mechanical, electromagnetic or electronic needle selection device is used to create a knitted fabric with any desired pattern.

FIG. 8 is an explanatory diagram showing a cross section of the needle beds 1, 2, 3, and 4 together with the carriage 17. Finally, Figure 9 shows the first
Figure 3 is a side view of the portion of the needle bed and carriage shown, with the double cam visible on the carriage 17; This double cam makes it possible, for example, to adapt the capabilities of the knitting machine according to the invention to the production of certain knitted fabrics, for example rubber stitches. Using the double cam and the arrangement shown in Figure 6b, the first, third, fifth, etc. needles 9 are transferred from needle bed 1 to needle bed 2 and at the same time the knitting operation proceeds to A two-form operation is performed. The needles 9 are then collected again into the needle bed 1, as shown in FIG. 6c. After completion of the carriage cycle, two rows of front rows instead of one are shrunken as shown in Figure 6f.
The knitting cycle shown in FIGS. 6 and 7 will be explained in more detail using FIGS. 10 to 17. Referring to FIG. 10, the last stitch of the knitted fabric 8 suspended from the needles 9 of the needle bed 1 is shown. Jack 5 on needle bed 1 is needle 9
is engaged with the hook 35 at the left end of the needle bed 2, and the jack 6 of the needle bed 2
and the grain transfer plate 7 is in the standby position. At this point, the butts 20, 21 of the jack 5.6 shown in FIG. 1 and the butt 22 of the striped transfer plate 7 are located in the cam grooves 23, 24, 25, respectively, as shown by the lines x in FIG. are doing. The jacks 5, 6 having high butts (highly protruding butts) and low butts (lowly protruding butts) and the stitch transfer plate 7 are arranged alternately in the needle beds 1 and 2 at a ratio of 1:1 as shown in Fig. 6b. Carriage 1 in Figure 15
7 moves leftward, the butt 20 of the jack 5 slides on the cam members 26, 27, and the high butts 21, 22 of the jack 6 and stitch transfer plate 7 slide on the half-operated cam 47 and cam 28. move.

(The cam 47 is called this because it acts only on high bats and does not act on low bats.) Jack 6 is the 10th
The jack 6 and the stitch transfer plate 7 are connected to the high butt 21 at the location indicated by the reference numeral 46 in the figure.
or 22, they move together even if either of them is activated. First, the high butt 21 of the jack 6 is driven by the half-movement cam 47. During this downward movement, the high butt 22 of the stitch transfer plate 7 is guided into the cam 28 via the cam groove. As a result, the high butt 22 of the stitch transfer plate 7 is further driven, and the high butt 21 of the engaged jack 6 is guided into the groove 29. The jack and stitch transfer plate 7 are connected to the cams 18 and 1
The high butt 20 of jack 5 is separated from the drive of cam 3.
Driven by the river. Furthermore, the cam 30 has a high butt 20
The jack 5 and associated needle 9 are driven to the intermediate part of the needle beds 1 and 2 as shown in FIGS. 16 and 15 XVO.

In this position, the jack 6 with a high butt engages the hook at the right end of the needle 9. During this operation, the jack 5 having a low butt is not actuated by the cam 30', so the 17th
As shown in the figure, the stitch 15 remains locked immediately behind the hook of the needle. When the carriage further moves to the left in the drawing, the jack 6 with the high butt is retracted by the cam 32, and the jack 5 with the high and low butts is withdrawn by the cam 31. Since the suppressing member 33 provided on the carriage 17 is positioned above the jack 6,
The needle 9 is prevented from being released from the jack 6. The needle 9 is then withdrawn into the needle bed 2 by the jack 6 with a high butt, and the jack 5 with a high butt without a needle
is withdrawn into the needle bed 1 as well as the jack 5 with the needle and low butt. During this operation, the hook 35 of the needle engages in the slope 34 of the jack 5, which has a slope 34 and has a high butt, and releases the needle 9. The jack and rope transfer plate are then moved from the positions shown in FIG. 1 or 10 to the positions shown in FIGS. 2, 11, and 15M. Before the needle 9 is retracted to its rearmost end, the thread guide member 48 inserts the thread into the needle hook, as shown in FIG. The old stripe 15 moves over the needle hook close to the latch and forms a new stitch with the yarn placed on the needle beds 1 and 2. The needle 9 must be returned to the needle bed 1 from the needle bed 2 shown in FIG. 11 without forming new stitches and without the old stitches coming off the needle 9.

As shown in FIG. 12, a jack 6 combined with a stitch transfer plate and a needle is placed in the first position along with a jack 5 having a high butt.
Cams 37, 38, 39 and 40' are shown in Fig. 5.
It is driven by this. As a result, the needle 9 is located at the midpoint between the needle bed 1 and the needle bed, and its left hook portion 35 is located just in front of the slope 36 of the jack 5 having a high butt. When the carriage further moves to the left in the drawing, the striped transfer plate 7 is pushed forward by the cam 41.

Since the jack 6 is held in the cam groove 42 by its high butt, the engagement between the bran grain transfer plate 7 and the jack 6 is released. The bran grain transfer plate 7 presses the needle 9 into the needle bed 1 and engages the needle 9 with a jack 5 having a high butt, and also moves the bran grain transfer plate 7, which is locked on the needle 9, to the right side of the needle. The jack 5 having a high butt is then driven by the cam 43 by sliding it onto the recess 55 of the stitch transfer plate (FIGS. 13 and 15, Xm). By this driving, the needle 9 and the stitch transfer plate 7 move the stitch 15 within the needle bed 2 from the recess 50 to the hook portion 44 of the needle, as shown in rainbow V in FIGS. 14 and 15. Then, the cam 45 returns the jack 5 and the needle 9 to the basic position shown in FIG. All the needles and the newly formed right and left stitches are located at the tip of the needle bed 1, as shown in FIG. 6c.

When the carriage moves from the left side to the right side in the drawing, the same operations as described above are performed with respect to the needles 10 and jacks 11 and 12 of the needle beds 3 and 4, and the green eye transfer plate 13.

As described above, the present invention eliminates the need for a presser plate and a complicated device for controlling the presser plate, which were conventionally required, and instead uses a circular transfer plate for executing hooking between adjacent needles in order to simply create a pattern. By using the present invention as a side grain transfer plate for manufacturing patterned products, that is, for transferring the yarn from the center of the tongue needle into the already closed hook, it is possible to provide a purl knitting machine that is simpler than conventional purl knitting machines.
