[Detailed description of the invention] This invention is a needle selection device of a hand knitting machine, and more specifically, a needle selection member is arranged to face the butt of any knitting needle among the knitting needles involved in knitting that are aligned at a predetermined position. Mount and fix on the needle bed,
Among the knitting needles aligned at the above-mentioned required position in relation to the sliding of the carriage, the knitting needle whose butt is facing the needle selection member and the subsequent knitting needle group are placed in one passage, and the other knitting needle groups are placed in another passage. The present invention relates to a needle selection device for a hand knitting machine that can be used for so-called partial pattern knitting in which a group of knitting needles that have been guided to one of the passages is further selected to create a pattern using only the group of knitting needles.

The purpose of this invention is to move the knitting needles whose butt faces the needle selection member as described above and the subsequent knitting needle group to one passage.
Other groups of knitting needles can be guided to the other path, and
The group of knitting needles guided to the other path is further guided to a path different from the one and other paths, and thereby, for example, when knitting the partial pattern, two needle selection members are placed on the needle bed at an arbitrary interval. The knitting needles are placed between the needle selection members and the corresponding knitting needles are guided to one passage and the other knitting needles are guided to the other passage, or the knitting needles guided to the other passage are further connected to the one passage and the other passage. By guiding the needle to a different path, needle selection corresponding to partial pattern knitting by knitting and pull-up knitting can be performed, and when knitting,
Two needle selection members are placed on the needle bed in correspondence with the double-end needles hanging the outermost stitches of the knitted fabric, and the knitting needle group corresponding to the amount of both-end needles is placed in one path, and the double-end needles are placed in the other path. By guiding the needles at both ends to a path different from the above-mentioned one and other paths, the outermost stitch of the knitted fabric can always be knitted with the same knitting yarn, and therefore a group of stitches knitted with the ground yarn can be To provide a needle selection device for a hand knitting machine that can perform needle selection corresponding to various pattern knittings, such as preventing vertical cracks from occurring between a group of stitches knitted with colored yarns. It is in.

The illustrated embodiment will be described below.

a and a' (Fig. 4) are a pair of needle selection members having a required length and a drawstring shell, and a front cam 1 and a rear cam 2 are opposed to each other at a required interval on the front and rear edges of the upper surface thereof. The two cams 1 and 2 thereby move back and forth a starting member 3, which will be described later, which passes between the opposing parts.

The needle selection members a, a' have their front edges facing the rear side of the butts 4 of the knitting needles that are aligned with the knitting standby position B involved in the knitting, and the indicators 5 displayed on the front edges of the needles are set to the required knitting needles. The butts 4 of the needles are opposed to each other, and are mounted on the needle bed 6 at a required distance from each other. By inserting it, it is fixed to the needle bed 6.

The tip of the protruding pin 34 is inserted into the second guiding cam 23, and the tip of the pin 25 of the second guiding cam 23 is exposed inside the retaining portion 29 (Fig. 2.3.5).

Reference numeral 35 denotes a fixture on which the guide parts 1 and 2 are removably mounted on both sides of the carriage 8.

(Figures 3 and 5). The carriage 8 forms passages for guiding the batt 4 by means of various cam groups mounted symmetrically on its lower surface, for example, a front knitting passage 2 and a rear knitting passage H corresponding to knitting of knitting knitting and pulling knitting. (Figure 2).

Reference numerals 36 and 36 denote a pair of rotary needle selection members mounted on both sides of the carriage 8, which rotate in relation to the sliding movement of the carriage 8, and which guide the butt 4 to select needles forming a required unit pattern. This is a known method in which needle selection is guided to either the front introduction passage 2 or the rear knitting passage E according to a needle signal.

The needle picking cams 27.27 are rotatably supported further outward than the rotating needle picking parts 36.36 at both ends of the carriage 8, and the guide cams 37 are disposed opposite to each other on the front side thereof.
．． 37, the bat 4 guided through the second guide passage opening is introduced into the carriage 8 into the front introduction passage, and the bat 4 guided through the first guide passage A on the rear side is introduced into the carriage 8. They each form a rear introduction passage (FIG. 2).

The needle handling cams 27, 27 are in a first position (FIG. 2) where they open both passages to the front and rear side introduction passages.
and a second position (FIG. 6) in which the rear introduction passage is closed and the first guide passage engages with the guided butt 4 to guide it to the front introduction passage. is biased to be displaced to the second position by a suitable biasing member (not shown), and its rear edge is engaged with the engagement piece 31 of the operating member 26, so that its operation By displacing the lever 32 of the member 26 inward, the member 26 is displaced to the first position against the bias (FIG. 3), and by displacing the lever 32 outward, the member 26 is displaced to the second position by the bias. (
(Fig. 5) is set in a permissible relationship.

Thus, the batt 4 introduced into the carriage 8 through the front introduction passage is subjected to the action of the rotary needle selection unit 36, 36, and selects needles into either the front or rear knitting passage 2 or E as described above. At the same time, the carriage 8 is guided from the rear introduction passage.
The batt 4 introduced into the knitting path 4 is guided to the rear knitting path E without being affected by the rotating needle selector body 36, 36 (Fig. 2).
Also, the butt 4 guided through the third guide passage 8 passes in front of the guide cam 37.37, is introduced into the carriage 8, and is moved to the front side without being affected by the rotary needle selector body 36.36. It is guided to formation path 2 (Fig. 6).

Then, the operating member 26 displaces the needle handling cam 27 to the first position by displacing the lever 32 inward, while positioning the pin 25 in the center of the engagement recess 29 to guide the first and second guides. While maintaining the cams 13 and 23 in the first position and positioning the pin 34 at the rear end of the elongated hole 28 to maintain the activation member 3 in the front side (Fig. 2.3), the lever is displaced outward. As a result, the pin 25 is engaged with one side edge of the engagement recess 29 and pushed to displace the second guide cam 23 to the second position, and the pin 34 is pushed to the front end of the elongated hole 28. As a result, the actuating member 3 is moved rearward via the biasing member 21 and the pin 18, and the first and second guiding cams 13, 23
are respectively displaced to the second position, and in conjunction therewith, the needle handling cam 27 is displaced to the second position (Figs. 5 and 6).
Set in relationship.

Next, the operation of this embodiment having the above-mentioned configuration will be explained with reference to FIGS. 2 to 4 in the case of partial pattern knitting by knitting and pull-up knitting, and by referring to FIGS. 2 to 4. The group is arranged in a cam arrangement corresponding to the braided stitch, and guide parts A and B are mounted on both sides, and the levers 32 of the guide parts B and B are set inside, and the first guiding cam 13
．． Second induction cam 23. The needle handling cams 27 are each set to the first position (FIGS. 2 and 3).

While performing the above-mentioned opening operation, all the butts of the knitting needles involved in knitting are aligned at position B as shown in Fig. 4, and some of the knitting needles are introduced into the front introduction passage to the rotary needle selection section. Needle selection member a, with index 5 facing the rear of roses 4a and 4b at both left and right ends of roses 4
Place a'.

In this case, the number of 4X mentioned above is the needle selection member a.

The required number can be set by appropriately adjusting the interval a'.

Now, when the carriage 8 is moved forward (in the direction of arrow 38 in Fig. 4), first the bat 4 other than the above-mentioned rose 4
is introduced into the first guide passage A of the guide body, passes through the passage A, and is guided to the rear knitting passage E of the carriage 8 via the rear introduction passage G (Figs. 2 and 4). ).

When the carriage 8 further moves forward, the butt 4x is introduced into the first guide path A, and before at least the rose 4a reaches the first guiding cam 13, the actuating member 3 is moved to the rear cam 2 of the needle selection member a. thereby engaging the first guiding cam 13
is displaced from the first position to the second position and guides the rose (4X) to the second guide passage opening (see FIG. 4).

Then, the above-mentioned rose) 4X is introduced into the carriage 8 from the second guide passage opening to the front introduction passage, and is introduced into the rotary needle selector body 36.
The needle selection is guided to either the front knitting passage 2 or the rear knitting passage H according to the required needle selection signal (Fig. 2,
Figure 4 2).

In addition, when the carriage 8 moves further forward, the above rose) 4X
The butt 4 in the forward direction of movement of the carriage 8 is introduced into the first guide path a, and the activation member 3 moves the needle selection member a' before the butt 4 adjacent to at least the rose 4b reaches the first guide cam 13. engages the front cam 1, thereby displacing the first guide cam 13 from the second position to the first position to allow the bat 4 to continue passing through the first guide passage I; , and is guided to the rear knitting passage of the carriage 8 via the rear introduction passage (Fig. 2, Fig. 4).
Figure 2).

Each bat 4 guided to the front and rear knitting passages 2 and 5 is guided forward to a desired position, and then introduced into the other guide body from the inside, and then aligned at position B from that guide body. (Figure 2).

In this way, by moving the carriage 8 forward to the required position, a partial pattern knitting is performed in which a pattern consisting only of the loose 4X needles selected by the rotary needle selection unit 36 is revealed.

It is also clear that when the carriage 8 moves backwards, a partial pattern is knitted by knitting in the same way as during the forward movement.

Next, the case of the pulling stitch will be explained with reference to Fig. 5.6.7. Various cam groups of the carriage 8 (the one on one side is not shown) are arranged in a cam arrangement corresponding to the pulling stitch. , the guide body b (one is not shown) is mounted on both sides, the lever 32 of the guide body is set to the outside, and the first and second guiding cams 13, 23 and needle handling cam 27 are Set each in the second position (Figures 5 and 7).

While carrying out the above operations, all the butts of the knitting needles involved in knitting are aligned at position B as shown in Fig. 6A, and the knitting needles are introduced into the front introduction passage and rotated for needle selection. The required number of roses to be selected by the member 36 to form a partial pattern) Roses at both ends of 4X) 4C,
4d, a needle selection member a' is placed on the rear side between the rosette 4c and the butt 4 adjacent thereto, with the indicator 5 facing the needle selection member a', and the needle selection member a' is placed on the rear side between the rosette 4d and the butt 4 adjacent thereto. The needle selection member a is placed with the index 5 facing the needle.

In this case, the number of the above-mentioned roses) 4X can be set to a required number by suitably adjusting the interval between the needle selection members a and a', as in the case of the above-mentioned knitting.

Therefore, when the carriage 8 is now moved forward (in the direction of arrow 39 in Fig. 6), the bat 4 at the rear in the direction of movement of the carriage 8 among the bats aligned at position B other than the above-mentioned rose 4 However, the bats 4 are prevented from continuing to pass through the passage A by the first guiding cam 13, and are thereby guided to the second guiding passage opening before passing through the second guiding cam 23. is further guided to the third guide passage 8, passes through the passage in front of the guide cam 37, is introduced into the carriage 8, and is guided to the rotary needle selector body 36.
is guided to the front formation path 2 without being affected by (
Figure 6 mouth, Figure 7).

Then, when the carriage 8 moves forward further, the above rose) 4X
is introduced into the first guide passage A, and at least the above rose) 4
Before C reaches the first guiding cam 13, the starting member 3 engages with the front cam 1 of the needle selection member a', thereby displacing the first guiding cam 13 from the second position to the first position, and the above-mentioned rose) 4
X is allowed to continue passing through the passage A, and the butt is guided through the first guide passage A and then engages the needle handling cam 27, thereby being guided to the front introduction passage and passing through the passage. The needles are then introduced into the carriage 8, and are guided by the rotating needle selection unit 36 to either the front knitting path or the rear knitting path in accordance with a required needle selection signal (FIGS. 6C and 6C). Figure 7).

In addition, when the carriage 8 moves further forward, the above rose) 4X
The bat 4 further forward in the direction of movement of the carriage 8 is introduced into the first guide path A, and is activated before at least the bat 4 adjacent to the right side of the bat 4d (port 9 in FIG. 6) reaches the first guiding cam 13. The member 3 engages with the rear cam 2 of the needle selection member a, thereby displacing the first guide cam 13 from the first position to the second position, so that the butt 4 continues along the first guide path a. The knitting needles are prevented from passing through, are guided to the second guide passage opening, and are guided to the front introduction passage 2 without being affected by the rotary needle selection body 36, similar to the butt 4 at the rear in the direction of movement of the carriage 8 from the knitting needle rose 4X. It is something that will be done.

Each of the bats 4 guided to the front and rear knitting passages C and E is guided to a desired position and then introduced from the inside into the other guide body b (not shown), and from the guide body B It is derived by aligning the position.

In this way, by moving the carriage 8 forward to the required position, a partial pattern is knitted by pull-up knitting that reveals only the pattern of 4X selected by the rotating needle selection unit 36, and the carriage 8 is moved back It is clear that even when the needle moves forward, partial pattern knitting by pull-up stitching is performed in the same way as in the forward motion.

Next, the effect of this embodiment with the above configuration is that in knitting, the double-ended needles hanging the outermost stitches of the knitted fabric are automatically guided to a fixed path separate from other knitting needles, and the outermost stitches of the knitted fabric are Section 2.5 shows the case where the outer end stitches are always knitted with the same knitting yarn and needle selection is performed to prevent vertical cracks from occurring between the stitch group knitted with the ground yarn and the stitch group knitted with the color scheme. 8.9 To explain with reference to FIG. 2, various cam groups of the carriage 8 are arranged in a cam arrangement corresponding to the knitting (FIG. 2).

With the guide parts mounted on both sides, the lever 32 of b is set to the outside and the first and second guide cams 13.23. The needle handling cams 27 are each set to the second position (Fig. 5.8).

While carrying out the above operation, as shown in Fig. 8A, all the knitting needles 4 The needle selection member a' is placed between the needle 4e and the adjacent butt 4 with the indicator 5 facing the needle, and the needle selection member a' is placed between the needle 4e and the adjacent butt 4, and the needle selection member a' is placed between the needle 4e and the adjacent butt 4. 4 and the needle selection member a with the index 5 facing backward between the
Place.

Now, when the carriage 8 is moved forward (in the direction of arrow 40 in Fig. 8), the above-mentioned rose) 4X is first introduced into the first guide passage A of the guide body (opening in the same figure), and at least the above-mentioned rose)
4e reaches the first guiding cam 13, and before the bat 4 adjacent to the bat 4e reaches the first guiding cam 13, the starting member 3
engages with the front cam 1 of the needle selection member a', thereby causing the first
The induction cam 13 is displaced from the second position to the first position, and the rose 1
-46 and guides it to the second guide passage opening, while allowing the bat 4 adjacent to the rose 4e to continue passing through the passage A (FIG. 3C).

When the carriage 8 moves further forward, the rose 4e is moved to the second position.
It engages with the guide cam 23 and is guided to the third guide passage 8, passes through the passage in front of the guide cam 37, is introduced into the carriage 8, and is not affected by the rotary needle selection body 36. As it is guided to the front formation passage 2, it is separated) 4
The butt 4 between e and 4f is guided through the first guide path a and then engaged with the needle handling cam 27, thereby guided to the front introduction passage, and introduced into the carriage 8 through the passage to be rotated and selected. The needle body 36 guides the needle selection to either the front knitting path 2 or the rear knitting path E in response to a required needle selection signal (FIGS. 8C and 9).

Then, the above-mentioned rose 4f is guided to the first guide path A by the continuous forward movement of the carriage 8, and the bat 4 adjacent thereto reaches the first guiding cam 13, and this rose 4f reaches the first guiding cam 13. Before, the activation member 3 engages with the rear cam 2 of the needle selection member a, thereby causing the first guide cam 1
3 is displaced from the first position to the second position to allow the bat 4 to continue passing through the first guide passage A, and engages with the rose) 4f, thereby causing the rose) 4f to move through the first guide passage I. It is prevented from continuing passage and is guided to the second guide passage opening, and is guided to the front introduction passage 2 without being affected by the rotary needle selection body 36 similarly to the rose 4e.

The bats 4X guided to the front and rear knitting paths 2 and E are guided to the required positions and then introduced into the other guide body from the inside, and are aligned and led out from the guide body at position B. be done.

In this way, by moving the carriage 8 forward to the required position, knitting and knitting that reveals the pattern selected by the rotary needle selection unit 36 is achieved, and when the carriage 8 is moved forward, the pattern selected by the needles selected by the rotating needle selection unit 36 is created. A knitting knitting is performed in the same way as in the case of knitting, and the outermost stitch of the knitted fabric, that is, the above-mentioned rose) 4e
, a knitting knitting method in which the stitches suspended from the 4f end needles can always be knitted with the same knitting yarn, and therefore no vertical cracks will occur between the stitch group knitted with the ground yarn and the stitch group knitted with the colored yarn. It is clear that it is possible to perform pattern organization according to the following.

As is clear from the above, according to this invention, in relation to the sliding movement of the carriage, among the required knitting needles involved in the knitting, the butt is opposed to the needle selection member fixedly placed on the needle bed. And the subsequent knitting needle groups can be guided to one passage, and the other knitting needle groups can be guided to the other passage, and the knitting needle group guided to the other passage can be further guided to a passage different from these one and other passages. I did it like this,
For example, when knitting a partial pattern in knitting or pull-up knitting as in the above embodiment, two needle selection members are used to select one group of knitting needles that corresponds between the needle selection members among the knitting needles involved in the knitting. It is possible to perform partial pattern knitting of knitting by guiding the other knitting needle groups in one passage to the other passage, and also to guide the other knitting needle groups in one passage with the corresponding knitting needle group between the needle selection members. It is possible to perform partial pattern knitting of pull-up stitches by guiding the other path from the above-mentioned other path to another path, which can be useful for diversifying pattern knitting, and
During knitting, two needle selection members are used to automatically select the two-end needle that suspends the outermost stitch of the knitted fabric among the knitting needles involved in the knitting, always in a path different from other knitting needles. A pattern created by knitting in which the needle is guided and the outermost stitches of the silk fabric are always knitted with the same knitting yarn, so that vertical splits do not occur between the stitch group knitted with the base yarn and the stitch group knitted with the colored yarn. It is something that can be organized.

In addition, these knitting operations can be performed accurately with a relatively simple structure consisting of a needle selection member, a guide body, a starting member first and second guiding cams, and an operating member. Since the needle handling cam of the carriage can be moved to a desired position in conjunction with the movement of the cam to either the first position or the second position, it is easy to handle.
