Reference numeral 14 designates a fixture for detachably attaching the actuator body to the carriage 5, and reference numeral 15 designates a guide groove into which the pin 11 is inserted.

The carriage 5 forms passages for guiding the butts of knitting needles, such as a front passage A, a rear passage opening, and an extracorporeal passage C, by means of a group of various cams mounted symmetrically on its lower surface.

Reference numerals 16 and 16' denote rotary needle selector bodies mounted on both sides of the carriage 50, which rotate in relation to the sliding movement of the carriage 5, and
This rotary needle selection body 16 is controlled by the needle selection members a and a'.
, 16', the butt of the knitting needle is guided to the front passage A or the rear passage opening in response to a required needle selection signal given by a needle selection signal display member 17, which will be described later. This is a known method.

The needle selection signal display member 17 is formed by perforating array signals of knitting needles constituting a unit pattern in multiple stages in a perforated portion and a non-perforated portion, and is arranged in a predetermined direction in relation to the sliding movement of the carriage 5. The card is transferred and provides the knitting needle arrangement signal, that is, the needle selection signal, to the rotary needle selection unit 16, 16' (hereinafter simply referred to as a signal card).

In this case, the signal card 17 includes, for example, the knitted fabric 17.
', i.e., among the needle selection members a and a', the next stage I displays the signal of the unit pattern Ia corresponding to needle selection member a. The array signals are displayed in the order of displaying the signal of the unit pattern nb corresponding to the needle selection member a' in stage (2), and further displaying the signal for guiding all the knitting needle butts 3 to the rear passage opening in the next stage (2). .

Reference numerals 18 and 18' denote a pair of guide cams provided symmetrically on the rear side of the body instrument passageway C, and these guide cams 18 and 18'
an operating position (solid line position in FIG. 6) in which the rotating needle selector body 16, 16' engages with the knitting needle butt guided to the front passage A and further guides it to the body passage C; The knitting needle butt is set so as to be movable to an inactive position (solid line position in FIG. 7) that allows the needle to move forward in the front passage A without engaging with the knitting needle butt.

Next, the operation of this embodiment having the above structure will be explained with reference to FIGS.
As shown in the figure, the guide cam 18 is mounted by the mounting fixture 14.
, 18' in working position, and Russell cams 19, 19'
are respectively set in positions where the body passages are opened, while vibrating all of the knitting needles involved in the required knitting to the B position, and a required number of knitting needle groups to advance them to the A position. 2. The needle selection member a is placed behind E.
, a' are placed in parallel with their guide walls 2, 2' held at the C position.

When the carriage 5 is moved forward (in the direction of the arrow 20), the needle selection member a is first introduced into the starting body, and this needle selection member a engages its guide wall 2 with the starting cam 9a and moves forward. death,
The corresponding knitting needle group 2 is advanced to position A, and the cam body 9 is displaced around the pin 10 to a position approximately parallel to the rear wall 7 against the bias of the spring 13 (see Figure 4). ).

Following the needle selection member a, the needle selection member a' is introduced into the starting part body, but in this case, since the cam part body 9 has been displaced as described above, the needle selection member a' is inserted into the guide wall of the needle selection member a'. 2' passes through the passage formed between the cam body 9 and the rear side wall 7 and remains at the C position, so that the knitting needle group E does not move forward (
(See figure c).

Each knitting needle of the knitting needle group 2 that has advanced to the above-mentioned position A is further selected by the rotary needle selection unit 16 in accordance with the signal displayed on the signal card 170 stage (■), and guided to the front passage A or the rear passage opening. The knitting needles guided to the front passage A are further guided to the body passage C by the guiding cam 18 and brought out to position D.

On the other hand, the knitting needle group E and needle selection member a remain at position B.
, the knitting needles located outside a' pass behind the rotary needle selection body 16 and are all guided to the rear passage opening, and the knitting needles are guided to the rear passage opening by the rotary needle selection body 16. It is guided to position B together with the second knitting needle.

When the needle selection member a is led out from the carriage 5,
The guide wall 2 is moved back by the return cam 9b of the other actuator body, passes between the cam body 9 and the rear wall 7 while retracting the cam body 9 a little, and returns to the C position. .

Next, when the carriage 5 is moved back, only the needle selection member a' is advanced by the actuating part body, and the corresponding knitting needle group H is moved forward.
The knitting needles are advanced to the rotating needle selector body 16'.
The needle is further selected in accordance with the signal in the stage (3) of the signal card 17, and guided to the front passageway (A) or the rear passageway entrance.

The knitting needles guided to the front passage A are guided to the body passage C by the guiding cam 18', and guided to the D position together with the knitting needles that have been selected during the forward movement of the carriage 5 and are already at the D position. .

Further, the knitting needles guided to the rear passage A, the knitting needle group 2, and the knitting needles located outside the needle selection members a and a' are guided to the B position in the same way as when the carriage 5 moves forward. .

Further, the needle selection member a' is also returned to the C position by the return cam 9b of the actuator body in the same manner as the needle selection member a.

In addition, in order to knit the desired needle selection pattern by reciprocating the carriage 5 as described above, the various cams of the carriage 5 are arranged according to the desired pattern knitting as shown in FIG. , and slide the carriage 5 in the direction of the arrow 21. The knitting needles in the above positions are guided to the front passage A by the Russell cam 19, and the knitting needles in the B position are guided to the rear passage opening. , the pattern is knitted in the above needle selection mode.

In this case, even if the needle selection member a advances the remaining knitting needles of knitting needle group 2 to position A again by the actuating member body, the rotary needle selection member 16 moves the knitting needles in response to the signal in column 2 of the signal card 17. Since all of the trains are guided to the rear passageway entrance, they do not interfere with the formation.

Next, a second embodiment shown in FIGS. 8 and 9 will be described.

In this embodiment, the needle selection members e and e' have different shapes, and the starting parts f and f' are also not symmetrical, and the starting parts f and f are not symmetrical.
' is that the actuating member of the first embodiment advances only the needle selecting member introduced first to a predetermined position by cooperation of the needle selecting member introduced first and the cam member. In contrast, the first aspect is that a specific needle selection member can be advanced to a predetermined position regardless of the order in which the needle selection members e and e' are introduced.
This is different from the actual implementation, but the other configurations are the same.

In the case of the first embodiment, if the needle selection members a and a/ are not brought close to each other at a certain distance, the subsequent needle selection member will also move forward to a predetermined position together with the preceding needle selection member, but in this embodiment Then, the distance between the needle selection members e and e' can be set arbitrarily.

That is, the needle selection members e and e' have the same length, but the width and the height of the guide walls 22 and 22' are different, and the width of the needle selection member e is different. The guide wall is wider and the height of the guide wall is higher in the needle selection member e'.

In addition, the starting parts f and f' are provided with journal cams 25 and 26 between the respective front and rear side walls 23 and 24, and the flexible cam parts 27 and 28 are inserted into grooves formed in the journal cams 25 and 26. The free ends of the cam parts 27 and 28 are normally brought into contact with the rear wall 24.

The cam parts 27 and 28 have a front side as a starting cam and a rear side as a return cam.

And the journal cam 25 and the cam body 2 of the activation body f.
7 engages with the guide walls 22 and 22' of both needle selection members e and e', and moves the knitting needle group corresponding to needle selection member e to position A, and also moves the knitting needle group corresponding to needle selection member e' to position A. It is set so that it advances to position B', which is slightly before position A.

Both needle selection members e are provided on the front side of the journal cam 26 of the starting part body f'.
, e' are provided with a bulging portion 26' corresponding to the difference in width, and the journal cam 26 and the cam body 28 are
is set to engage only with the guide wall 22' of the needle selection member e/, and advance the corresponding knitting needle group to the A position.

Thus, the starting body f is mounted on the right side of the carriage, and the starting body f' is mounted on the left side, and the needle selection member e is placed on the left side, the needle selection member e' is placed on the right side, and both guide walls are mounted on the needle bed. 22 and 22' are held in the C position and juxtaposed with each other, and the carriage is slid.As a result of the forward movement (in the direction of arrow 29 in Fig. 8), both needle selection members e and e' are advanced by the actuating body f. Then, only the knitting needle group corresponding to the needle selection member e advances to the A position, and only the needle selection member e/ moves forward by the actuating member f′ by the backward movement (in the direction of arrow 30 in FIG. 9). The knitting needle group moves forward to the A position.

In this way, according to both of the above embodiments, the two needle selection members are advanced separately each time the carriage slides, and only the group of knitting needles that have been pushed by the butt and advanced to the desired position are further moved to the rotating needle selection unit. Since the needles can be selected by the body, it is possible to perform so-called partial pattern knitting in which a desired pattern is created in the part knitted with both knitting needle groups, and one pattern can be knitted with both knitting needle groups or each knitting needle group. It is also possible to configure separate patterns for each pattern.

As is clear from the above description, according to the present invention, a plurality of needle selection members are mounted on the needle bed so as to be movable back and forth,
One of the needle selection members is placed in the desired position, facing the butts of some knitting needle groups among the knitting needles involved in the knitting, and is removably attached to one side of the needle selection member when the carriage moves forward. advance some of them to engage the butts, select the butts with a needle selection unit mounted on a carriage,
Also, when the carriage moves back, the other of the needle selection members is advanced and engaged with the butts by the actuating member detachably attached to the other side, and the needle selection members with these butts mounted on the carriage are moved forward and engaged with the butts. The needle selection member selects needles, and each group of knitting needles corresponding to each needle selection member enables partial pattern knitting, for example, as shown in the embodiment, and can also be useful for diversifying pattern knitting. be.

In addition, since the needle selection member has a pin protruding from the bottom surface inserted into the needle groove so that it can move back and forth, it does not move blindly from side to side, disrupting the correspondence with the butt, or falling off the needle bed. Just by looking at the state in which the needle selection member faces the butt, the position where the partial pattern appears can be easily and accurately determined.

Moreover, the number of knitting needles that will reveal the partial pattern is specified by the size of the needle selection member that opposes the bat, so there is no need for the troublesome work of counting and checking the number of knitting needles during knitting. Good workability.

Furthermore, since the activation body is detachably attached to both sides of the carriage, for example, an existing carriage can be used without any modification to the cam arrangement, etc., and the activation body can be attached to both sides of the carriage. By providing this, it can be manufactured easily, and if the activation body is removed when not in use, it will not interfere with other knitting operations.
