This guide member 34 has a lower end edge that is a mirror slope inclined slightly forward, and the protrusion 11 of the jack 9 that moves along the front surface of the horizontal cam 21 is rearward as shown in an enlarged view in FIG. The projection 11 of the jack 9, which serves as a member for guiding the jack 9 along the side, and which is projected forward when the selection member 24 projects from the front surface of the horizontal cam 21 as shown on the left in FIG. 2, is shown by the chain line in FIG. The downward movement in which the protrusion 11 passes through the flow line A, which passes through the lower surface of the guide member 34 to the front side, is caused by manipulating the spring 12 downward. Due to this action, it moves upward to be at the same height as the protrusion 11 passing through the rear side, and there is no danger of it returning to the train entrance on the rear side again. The butt 7 of the selected knitting needle 6 is attached to the mounting surface 19 on the lower surface of the plywood 14 in two positions, front and rear, along the front and rear needle paths x,
A cam group 35 is arranged to feed yarn from separate yarn feeders to the hooks of the knitting needles 6 that pass through the respective needle paths x and y, thereby making it possible to simultaneously knit bran in two colors. .

The knitting needles 6, which have been guided in separate needle paths x and y and have undergone knitting operations, are guided laterally with the butts 7 aligned on the rear side of the lowering cam 36, and escape from the lower surface of the carriage 13. In this configuration, the butt 7 of the rope needle 6 is thrust forward by the jack 9 in front of the selection member 24 and in front of the sorting and enlarging cam 27. Each outer side guide cam 37 of the cam 36 is formed with a cutout surface 38 whose rear side is fixed, and the front part of the sorting and enlarging cam 27 is protruded forward by the sorting member 24 and the enlarged cam 2

to be fixed. - The moving plate 42 is moved between the first position 1 and the second position by operating the rotary handle 48. FIG. 8 shows the first position 1, where the spring 31 of the switching member 32 is moved backward by the elasticity, and the spring 31 of the operating pin 33 (
(not shown) and backward movement due to elasticity. When the switching member 32 is switched to the position shown in the figure, the sliding plate 29 moves rearward to move the sensing member 30 to the second needle rest path 1.
8 protrudes from the front to the operating position, and at the same time passes through the lower surface of the horizontal cam 21 to hide the selection section 24 on the lower surface of the horizontal cam 21. On the other hand, the tip of the guide cam 22 comes into contact with the rear wall 16 of the yield passage 16 due to the rearward movement of the operating pin 33 as described above. When the moving plate 42 moves to the second position, the switching member 32 moves forward in contact with the front surface of the cam 44, and the operating pin 33 moves forward by the inclined guide surface 46 of the cam hole 45. When the switching section 32 is switched and arranged as described above, the sliding plate 29 moves forward to retract the sensing member 30 from the second needle rest passage 18 to the forward inactive position, and simultaneously moves the selection member 24 to the horizontal cam. It protrudes from 21 to the front. At the same time, guide cam 2
2 flips up the tip to open the internal combustion in each rear passage a.
The operation of the first embodiment will be explained with reference to FIG. 7. When the rope needle 6 is pressed and moved to the rearmost position within the needle groove 2 as shown at the rightmost end in FIG. a certain jack 9
is pressed, and in that position the bat 10 is in the first position of the carriage 13.
The butt 7 corresponds to the side of the needle rest passage 15 and the second needle rest passage 18 to a rear needle rest position in which no knitting operation occurs by the carriage 13, and the jack 9 is moved from that position. When the striped needle 6 is pushed forward a little, the butt 10 corresponds to the side of the guide path 16, and the striped needle 6 moves the butt 7 to the side of the entrance of the needle path y, corresponding to the knitting needle involved in knitting. Become. Therefore, the movable plate 42 is placed in the first position 1 only when the knitting needle butt 7 is passed through the needle paths x and y as shown in FIGS. Corresponding striped needles 6 are selected so that the butt 7 corresponds to the entrance side of each of the needle paths x and y using a needle device (not shown). As described above, the knitting needles 6 and jacks 9 are divided into two groups, front and rear, respectively, and the movable plate 42 is set to the first position 1, and the carriage 13 is moved to the second position on the needle bed 1.
When moving in the direction of the arrow in the figure, the butts 10 of the jacks 9 in the rear group enter the first needle rest path 15, and the butts 10 of the jacks 9 in the front group enter the guide path 16.

Also, the butts 7 of the green needles 6 in the rear group are in the second needle rest path 1.
8, the front group of knitting needles 6 are divided into front and rear by the needle selection device as described above, so those butts 7 are aligned with the needle path x.
and y, and the knitting yarns of A-color and Otsu-color are fed separately to each knitting needle hook to produce two-color simultaneous knitting bran, and then
It gathers behind the left lowering cam 36. On the other hand, the guide passage 1
When the butt 10' to the leftmost end jack 9 of the group of jacks 9 entered in 6 passes in front of the selection part village 24 protruding from the front surface of the horizontal cam 21, it passes through the second needle rest path 18. The right end of the knitting needle butt passing through the selection member 24
The knitting needle butt 7' at the end adjacent to the left of the end jack butt 10' passing in front of the end jack butt 10' presses the sensing member 30 in the second needle rest passage 18 as shown in FIG. 2 to hold the selection member 24 in a protruding state. , the end jack butt 10' is projected forward and pushes the butt 7a of the bran needle 6 on the front side into the cutout surface 38 of the bran guide cam 37. Further, the end jack 9 with the butt 10' pushed out moves the protrusion 11 at the rear end to the front end of the guide member 33 along the flow line A shown by the chain line in FIG. The movement is forced by the protruding selection member 24, but after moving forward, the elasticity of the spring 12 makes it higher than the lower edge of the guide member 34 as shown by the chain line. Therefore, even if the butt 10' of the end jack 9 moves to the left, the permanent magnet 2
6, butts 7 of the front knitting needles 6 are pushed out and moved forward to the front of the knitting needle selection cam 39. When the second and subsequent groups of butts 10 from the left pass in front of the selection member 24, the selection member 24 is hidden behind the lower surface of the comb cam 21 because there is no knitting needle butt that touches the sensing member 30 and pushes it forward. Therefore, the bat 10 is attracted by the permanent magnet 26 and the recess 2
5, the butt 7 passes along the flow line opening on the rear side of the striped needle sorting cam 39 because it does not push out the knitting needles 6 on the front side by going under the lower surface of the notch 28 of the sorting and enlarging cam 27. When the butt 10'' of the rightmost end jack 9 of the group of jacks 9 passing through the guide path 16 passes in front of the selection member 24 as shown in FIG. The butt 7'' of No. 6 presses the contact surface 30a of the sensing member 30.

For this reason, the selection member 24 protrudes and pushes out the butt 10'' of the end jack 9, acting in exactly the same manner as the leftmost end jack 9 described above, and moves the butt 7b of the front edge needle 6 to the front side of the needle selection and sorting cam 39. In short, the leftmost and rightmost butts 7a and 7b of the group of knitting needles selected forward by the butts 10 at both ends of the group of jacks 9 that have entered the guide path 16 are shown by thick black lines. The needle is selected so that it always follows the needle path x by the operation of the sensing member 30 that the butt 7 that passes through the second needle rest path 18 comes into contact with, and this principle is based on the number of groups of jacks 9 that enter the guide path 16. It does not change whether it increases or decreases.

To separate the other bran needle bats so that they pass through the needle paths x and y, the needle selection device is used as described above. If the needles are selected so that the butts 7a and 7b of the knitting needles 6 at both ends always pass through the needle path x as shown in FIG. The purpose of the knitting yarn B is to hang it over the needle stems of bran needles at both ends of the folded end and then hang it over the hooks of the knitting needles passing through needle path y to form stripes. As a result, the striped texture becomes as shown in Fig. 10, and since the folded end y' of the green yarn in O is slack, there is no slack at the end y', and the knitting yarn follows the chain line. Eliminate the defect that the knitted fabric is pulled in the direction of the arrow bran and tightened due to the tension of the stripes m at the end due to the knitting yarn B when passing through.

When the movable plate 42 is rubbed at the second position 01, the sensing member 30 retreats from the second needle rest passage 18 as shown in FIG. 4, so that it no longer senses the striped needle butt 7 passing through the passage.

On the other hand, the selection member 24 protrudes to the front of the horizontal cam 21, but at the same time the guide cam 22 springs up and moves into the rear passage a.
Since the inside of the jack 9 is opened, the butts 10 of the group of jacks 9 that have entered the guide passage 16 do not pass through the front surface of the horizontal cam 21 and the selection member 24. Therefore, no end needle selection is performed. In this embodiment, the butt 7 of the bran needle 6 divided at the front is passed through only the needle path y to knit flat stripes. 11th, 1st
FIG. 2 shows a second embodiment showing a modification of the first embodiment, in which the contact surface 30a of the sensing member 30' provided on the sliding plate 29 of the selection member 24' is inserted into the first needle rest passage 15 from the front. The structure is such that the butt 10 of the jack 9 in the rest position protrudes and passes through the passage 15 comes into contact with it, and other parts that are equivalent to the first embodiment are given the same reference numerals as in the first embodiment.

In this embodiment, since the switching member 32 is positioned almost side by side with the operation pin 33, the movement permitting portion 44a, actuating cam 44b, and holding portion 44c provided on the moving plate 42 in FIG. 8 are formed in accordance with this position. . In this embodiment, the sensor village 30'

Claims (1)

[Claims] 1 A carriage that is slidably mounted on a needle bed that supports knitting needles or jacks for operating the knitting needles, and that guides the knitting needles involved in knitting into two courses to knit patterns, etc.; a sensing member that is disposed protrudingly within a moving path of a resting knitting needle at an end not involved in knitting adjacent to an end knitting needle of a group of knitting needles or a jack corresponding to the resting knitting needle, and that moves by coming into contact with said resting knitting needle or jack; a selection member that moves the end knitting needle or a jack corresponding to the end knitting needle to a position where it can be introduced into a specific one of the two courses in relation to the movement of the sensing member; In the end needle selection device, the end knitting needle can be selected directly or through a corresponding jack based on a selection movement effect of an operating position protruding within the movement path of the
The device is movably moved between a non-working position where it is retracted from the moving path and does not come into contact with the rest knitting needles or the jack, and is always biased to the working position by a spring means, A movable plate connected to the sensing member and movable within a certain range is provided, and the movable plate includes:
a movement permitting part for arranging the sensing member in the operating position at one position of the movement and allowing the movement; An end needle selection device for a knitting machine, comprising: an operating cam that moves the sensing member from the operating cam to a non-active position; and a holding portion that holds the sensing member moved by the operating cam at the non-active position. .
