Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is characterized in that a twenty-one dollar jack is arranged in a needle groove at the rear of a knitting needle so that it can move forward and backward, and its butt can freely sink into the needle bed. This invention relates to a stitch transfer device in a flat knitting machine configured to be selectively controllable by an electrical or mechanical knitting needle device to a position of protruding onto a needle bed or a position of sinking into a needle bed.

Various types of flat knitting machines have been developed that are equipped with stitch transfer devices in order to obtain stitch transfer patterns and/or to reduce stitches during a certain process of knitting.

However, in conventionally known transfer devices, the relationship between the running direction of the carry stitch and the transfer direction, which can be transferred by a pair of front and rear transfer cam devices, is specified for each flat knitting machine, as shown in Fig. 1. In the most basic system, when the carriage moves to the right, a set of front and rear transfer cams on one side transfers the stitches from the front side to the rear, and when the carriage moves to the right, a set of front and rear transfer cams on the opposite side transfers the stitches. The device allows the stitches to be transferred from the rear side to the front side, and as shown in Figure 2, a pair of front and rear transfer cam devices can transfer the stitches in either direction. Furthermore, the running direction of the carriage that can be transferred by a pair of front and rear transfer cam devices is limited to either rightward movement or leftward movement.

The purpose of this invention is to use a pair of front and rear shifting cam devices to prevent the carriage from being directed in any particular direction, as shown in FIG. However, the present invention is intended to provide a transfer device that can transfer the stitches even if the stitches are transferred.

In addition, in conventional stitch transfer devices, the track that guides the knitting needles to the stitch transfer position and the stitch receiving position (in particular, the latter transfer receiving track is operated by a cam device that pinches the butt of the knitting needle from above and below and acts on the butt). Because of this structure, if a stitch transfer problem occurs and the butt of the knitting needle is damaged within the guide track, the expensive knitting needle, which has a subsequent stitch transfer mechanism, will be damaged like a chess player. Another object of the present invention is to provide a transfer device which does not have this disadvantage.

As mentioned above, the needle transfer device of the present invention is particularly capable of controlling the twenty-one dollar jack between the working position on the needle bed and the non-working position in the needle bed by an electrical or mechanical needle selection device. By taking advantage of the advantages of the flat knitting machine, that is, by skillfully utilizing the existence of the needle selection mechanism in such a flat knitting machine,
This is a solution to the above objectives, and the gist is that in a flat knitting machine with the needle selection mechanism as described above,
The knitting needle and the twenty-one dollar jack are not directly connected in the forward and backward direction of the knitting needle, and a pair of cam devices for stitch transfer are provided on the front and rear cam plates on the front and rear cam plates, respectively. It is composed of a stitch transfer cam group that acts on the butt of the needle jack and a stitch transfer cam group that acts on the butt of the needle jack, and the stitch transfer cam group that acts on the butt of the needle jack is connected to the stitch transfer cam group that acts on the butt of the needle jack. a pair of retractable transfer raising cams that push up against the butts of the needle jacks at the front end of the carriage in the direction of travel; A stitch transfer cam that is configured with a pair of recessed transfer receiving cams that push up against the butt and a jack guide cam that pushes down against the butt of the twenty-one dollar jack, and that acts on the butt of the knitting needle. The group is composed of upper and lower transfer guide cams, and between the upper and lower transfer guide cams, only the butt of the knitting needle pushed up by the twenty-one dollar jack on which the transfer raising gum acts can be moved from either the left or right direction. A pair of actuating transfer position guide tracks are configured, and the lower surface of the lower transfer guide cam acts only on the butt of the knitting needle pushed up to the transfer receiving position by the twenty-one dollar jack on which the pair of transfer receiving cams act. A push-down guide surface is provided.

Next, the present invention will be explained in more detail by referring to an embodiment. In this embodiment, a pair of carriages 2 ,2′
When implemented in a conventional type of flat knitting machine in which the needles move back and forth, the front needle bed 1, the rear needle bed 1', the front carriage 2, and the rear carriage 2 are each provided with the same structure according to the present invention. The following explanation will mainly be made regarding the front needle bed 1 and the front carriage 2.

As shown in FIG. 4, each needle groove 4 which receives the knitting needle 3 in a freely forward and backward manner allows a twenty-one dollar jack 5 to be freely advanced and retracted behind the knitting needle 3, and a butt 6 of the twenty-one dollar jack in the needle bed. A twenty-one dollar jack 5 having a hairpin-like rear end 5b and having elastic flexibility extends rearward with a depth such that it can be received so as to be able to sink therein. It is arranged with its front end 5a and rear end 5b in contact with the bottom of the needle groove 4.

When the center of the twenty-one dollar jack 5 is pressed from above, it curves (see the chain line), and its butt 6, which is normally maintained in a state where it can protrude above the needle bed 1, 1
It is made to sink inwards.

Further, this needle groove 4 allows a pusher 7 and a select jack 8, which will be described next, to be moved forward and backward and swingable, respectively, at the upper part of the needle jack 5, behind the butt 6 of the needle jack. It has a groove depth that allows it to move freely.

A pusher 7 having a butt 9 on the upper surface near its front end is disposed above each twenty-one dollar jack 5 in the needle groove 4.

The footshear 7 has a convex portion 7a formed on the lower surface of the front side thereof, which contacts the upper surface of the twenty-one dollar jack 5 at a position near the butt 6 of the twenty-one dollar jack, and three small recesses formed on the lower surface of the rear end thereof. 7b, 7c, and 7d is lightly engaged with a click stopper 10 made of piano wire that can pass through the needle groove 4 and into the needle bed 1.
It is arranged so that it can move forward and backward, and its front side can swing freely around the click stopper 10 as a fulcrum.

Further, above each pusher 7 in the needle groove 4, there is a select jack 8 which can push out the pusher 7 when its front end collides with the rear surface of the pusher 7 of the pusher 7. It is loosely sandwiched between the straps 11 and 12 of the floor 1 near its front end, and is arranged so that it can move forward and backward, and its rear side can swing.

When the top surface of the bat 7 is selectively pushed by a cam device (described later) on the carriage 2, the punosha 7 described above is oscillated, pushes the top surface of the twenty-one dollar jack 5, and presses the top surface of the twenty-one dollar jack 5. It has the function of causing the needle bed 1 to settle into the needle bed 1.

In the flat knitting machine of this embodiment, the position of the butt 9 of the puncher 7 is controlled by the forward action of the select jack 8 selected by the electromechanical needle selection device on the carriage and the cooperative action of the cam device on the carriage. However, in the illustrated embodiment, the position of the butt 9 in the forward and backward direction of the pusher 7 is particularly determined by the forward movement of the select jack 8 and the position on the carriage. Through the cooperative action of the cam device (the clear cam 46, half clear cam 47, etc. described later), the forward position (■) and the intermediate position (■) shown in FIG. 4 are achieved.
Then, the click stopper 10 and the recess 7by7 formed on the lower surface near the rear end of the pusher 70 are selectively positioned in one of the three positions of the retracted position (3).
It is possible to hold it swingably by having a weak bonding relationship with either one of c and 7d.

The select jack 8 causes the tip of the object selected by the control mechanism on the carriage to collide with the rear surface of the butt 9 of the pusher 1 to push the pusher 7, which is in the backward position ■, to the forward position ■. As mentioned above, the select jack 8 is arranged so as to be able to move forward and backward within the needle groove 4 and to be able to swing freely on the rear end side.
At its most retracted position, its rear end 8a projects rearward from the needle groove 4, and when the collect cam 13 on the carriage 2 acts on this rear end 8a, the select jack 8 moves its free end. The side is brought from the position shown in Figure 4 to the raised position to prepare for needle selection. A select butt 14 for operating the select cam 48 of the device 50 and displacing it to the lowered position shown in FIG. 4 is provided protruding from the upper surface of the swingable free end side.

Further, the protruding position of the select butt 14 is selected from among several different positions in the longitudinal force direction set in advance for each select jack 8. This is omitted because it is not directly related to this, but for example, select jacks 8 of six different standards, each with select butts 14 protruding from different positions corresponding to the positions of six select cams 48, can be selected at the same position. Bat 14
The select jacks 8 are controlled by an electromechanical needle selection device 50 provided on the carriage when the carriage 20 is running. The select cam 48 to be
When the select jack 8 of the selectable standard is actuated on the select butt 14, only the select jack 8 of the selected standard can be lowered with its free end side to the position shown in FIG. There is.

Furthermore, a raging butt 15 is provided protrudingly at a predetermined position on the upper surface of the free end side of each select jack 8.
When the carriage 2 moves, when the raising cam 17 provided on the carriage 2 acts on the raising butt 15 of the select jack 8 which is kept at the free end side or the raised position, the selecting jack 8 Propelled by the raising cam 17, the pusher 7 is moved forward by an amount that can be pushed from the backward position (■) to the forward position (■). Also, at a predetermined position on the upper surface of each select jack 8, a clear butt is provided. When the select jack 8, which has a protruding portion 16 and is moved forward as described above, is pushed back by the clearing surface 18a of the guide cam 18 on the carriage 2 that acts on the clear butt 16, the rear end of the select jack 8 is pushed forward. The portion 8a is returned to its original position located in the action area of the collect cam 13 on the carriage 2.

The pusher clear cam 46 and the pusher half clear cam 4T are provided at the center and both ends of the cam plate 21.

Further, in the flat knitting machine of this embodiment, when the needle selection device 50 provided on the carriage and controlled by an electric control mechanism advances and retreats the selection of the select jack 8 while the carriage 20 is running, the selection can be made. The pusher 7 can be moved from the retreat position (■) to the advance position, and when the pusher 7 is brought to the advance position (2) and the clear cam 46 is applied thereto, it is returned to the retreat position (2) and the half clear cam is moved. When 47 is applied, it can be moved back to the intermediate position ■, and the pusher
By controlling the position of the knitting needle 7 to any of the above positions ■ to It is divided into groups (needle selection), and pusher 7 of group (A)
The butt 9 of group (B) is kept at the forward position (the action trajectory of the cams 40, 42, 47), and the butt 9 of the pusher 7 of group (B) is kept at the retreat position III (the action trajectory of the cams 41, 43, 45). It is designed to sag.

Next, the stitch transfer action of the stitch transfer device according to the present invention will be explained with respect to the device of the above embodiment. FIG. In this figure, the retractable cam device protruding from the cam plate 21 moves the pusher 7 to the action position on the bat 9, and the retractable cam device protrudes from the cam plate 21 to the action position on the twenty-one dollar jack 50 pad 6. The cam device protruding from the cam plate 21 is shown painted black.

As can be seen from the figure, the illustrated example is the needle selection device 50 on the left side.
As a result, the pushers 8 are sorted every three into (A) group (■ position) and (B) group (■ position), and the half clear cam 47 separates (A) group from ■ position to ■ position, that is, (q An example is shown in which the needles are selected into a group, but the pusher 7 selected in this way is the 6th needle.
When the pusher cam 45 reaches the e position in the diagram, the pusher cam 45 is controlled to the protruding position, so the pusher 7 of the group (B) is oscillated with the upper surface of the butt 9 being pushed by the pusher cam 45. (B)
The twenty-one dollar jack 50 butt 6 of the group is retracted into the needle groove 4 by the action of the pusher cam 45 and the pusher 7 when the push-up slope 31b of the transfer raising cam 31 in the protruding position passes; It passes through a groove having slopes 31a and 32a at both ends and does not enter the transfer track.

However, since there is no pusher cam that acts on the pusher I of group (C), when the pusher cam 47 is in the retracted position (this corresponds to pusher 7 of group A), there is no pusher cam that acts on it. Since the twenty-one dollar jack 50 butt 6 is maintained at the protruding position above the needle bed 1 where the transfer raising cam 31 can act, (the twenty-one dollar jack 50 of group q)
Only the pad 6 is pushed up by the action of the push-up slope 31b of the transfer raising cam 31 at the left end of the stitch transfer cam group 24, and only the knitting needles 3 of this group (Q) are guided to the transfer position guide track T. .

Subsequently, the twenty-one dollar jack 5 is retreated by the push-down surface 30c of the jack guide cam 30 until it reaches the center position of the stitch transfer cam group 24, but
When the knitting needles 3 guided by the transfer position guide track T reach the center of the track T, on the opposite needle bed 1', in this embodiment, the pusher cam is moved for any group of pushers. is not working and the transfer receiving cam 32/ is projected to the working position, so each twenty dollar jack 5' is pushed up by the upward slope 32'b of the transfer receiving cam 3z. Among the knitting needles 3' pushed up to the transfer receiving track R, those that act on the knitting needles 3 on the transfer position guide track T receive the stitches, and each knitting needle 3' is retracted by the push-down guide surface 28'c of the transfer guide cam 28', and the transfer operation is completed.

In this embodiment, the transfer raising cam 31' and the transfer receiving cam 32' are arranged in an integrated block, so both the cams 31', 3
2', the butt 6 of the 21 dollar jack 5' is pushed up by a predetermined amount by the transfer receiving cam 32'.
a guide surface 31'c for acting on and lowering it;
is formed on the transfer raising cam 31' side, but as in another embodiment shown in FIG. 7, the transfer raising cam 31 and the transfer receiving cam 32 are constructed as separate bodies and can be controlled individually. In this case, the guide surface 31c as described above is not necessarily required, and the guide cam 37 may be used to lower the twenty-one dollar jack.

Further, as is easily understood from the above, the transfer raising cam 31 and the transfer receiving cam 32 may be constructed so that they can be controlled separately as shown in FIG. If the mechanism has the structure as in the above embodiment, the needle selection device 50 may be provided in the same phase as the two knitting cam groups 25 as shown in FIG. In other embodiments, although not shown, it may be provided in the same phase for each knitting or cam group (multiple sets) and for each shift cam group (multiple sets).

Further, in the above embodiment, an example was shown in which all the knitting needles 3' were guided to the receiving position on the needle bed 1' on the opposite side, but as shown in FIG. Retractable pusher cams 71, 72, 7 that cover the action area on the starting end side of 32'
3 at each position ■ to ■, only the twenty-one dollar jack 5 selected by the needle selection device is made to act on the transfer receiving cam 32', and only the selected needle M needle 3' is provided. , the transfer receiving trajectory R
It can be used to guide you.

Further, the above embodiment relates to a flat knitting machine configured to be able to selectively control the butt of the twenty-one dollar jack to a protruding position above the needle bed or a submerged position within the needle bed using an electric needle selection device. ℃
・Although an example in which the present invention can be implemented has been explained, the needle selection device is
It goes without saying that the needle selection device is not limited to an electrical needle selection device, and the needle transfer device of the present invention can be implemented even if the needle selection device is mechanical.

The present invention has been described above with reference to the embodiments, but the needle transfer device of the present invention has a set of needle transfer needles arranged on the front and rear needle beds so that the needles can be easily embedded from the above points. The cam group controls the stitch movement while the carriage is running.
Only the knitting needles selected from one needle bed side are necessarily guided to the transfer position guide track at a position before the center of the stitch transfer cam group, and then the knitting needles are guided to the transfer position on the track to the rear position. This is done by guiding the knitting needles from the opposite needle bed side to the transfer receiving track at a position after the center position of the stitch transfer cam group. For eye transfer like this,
It has the excellent advantage of being able to do this both when the carriage moves in either the left or right direction, or in any direction forward or backward.

Therefore, according to the stitch transfer device of the present invention, a required set of stitch transfer cam groups disposed at the middle position or both sides of the knitting cam group and a required number of knitting cam groups can be used. Therefore, when the carriage moves in any direction, it is possible to freely shift the stitches in either the forward or backward directions on the relevant course, and reduce or reduce the stitches.
It is possible to arbitrarily select and perform the transfer pattern knitting and the knitting patterns using the knitting cam group.

Furthermore, as explained in the above embodiment (Fig. 7), if the needle selection mechanism is skillfully combined, only the selected knitting needles can be guided to the transfer receiving trajectory. The following trouble occurs when a knitting needle that is on the needle bed on the stitch-receiving side and does not receive a stitch passes through the transfer receiving track, that is, if the stitch is pushed up unnecessarily by the knitting needle, the stitch becomes untidy. , there is a risk of dropped stitches, and there is a risk that the knitting yarn at the rest position may be fed to the knitting needles that are resting at both ends of the knitting course (knitting needles that have no stitches and are not particularly moved back). In addition, in the stitch transfer device of the present invention, the knitting needles and the twenty-one dollar jack are not connected, and the transfer device guides the knitting needles to the transfer receiving position. The receiving position guide trajectory R is as follows for the butt of the knitting needle:
It is composed only of the lower surface of the lower transfer guide cam, which acts only on the front surface, and the lower part of the transfer guide cam is empty, so if there is a problem with the butt of the knitting needle pushed up to the transfer receiving position. If this occurs, it can escape into the void space, thereby avoiding troughs such as damage to subsequent knitting needles.

Therefore, according to the stitch transfer device of the present invention, since it has a stitch transfer mechanism, it is also economical in that the consumption of expensive knitting needles due to breakage is reduced accordingly.
