Description

[Detailed description of the invention] (Field of industrial application) The present invention is a hand knitting machine carriage that is capable of knitting two colors at the same time. This invention relates to a carriage for a hand knitting machine that can switch between two-color simultaneous knitting and knitting as appropriate.

(Prior art) Conventionally, as a prior art of this type of carriage for hand knitting machines, there is the Utility Model Publication 57-1, which was previously proposed by the same applicant.
There is one described in Publication No. 45275. In the case of the carriage for a hand knitting machine of this publication, a needle selection member (a lowering cam and a needle selection cam) is used to sort the butts of knitting needles into a needle selection position and a knitting preparation position after knitting is completed.
In the case of argyle knitting, there is a cam to advance the butt of the knitting needle after knitting to the front of the flange removal position, and a cam to move the butt of the knitting needle advanced by the flange removal cam back to the position immediately before the flange removal position. Retracting cams are arranged in series on the left and right. In the case of argyle knitting using the same carriage, the butts of the knitting needles pass through the position of the needle selection member, even though there is no need to sort them into two groups, front and rear, after knitting is completed. (particularly the lowering movement of the butt by the lowering cam), and thereafter the bellows were moved forward to the bellows removal position by the bellows removal cam.

(Problem to be solved by the invention) Therefore, in the carriage of the above-mentioned publication, since the needle selection member, the tongue removal cam, and the retraction cam are arranged in series on the left and right, the carriage There was a problem in that the length in the left and right direction inevitably became longer, and the carriage had to be made larger.

In addition, in the case of argyle knitting, the butts of the knitting needles after knitting are subjected to unnecessary needle selection action by the needle selection member, resulting in noise caused by the lowering and rising (return) of the knitting needles, and noise caused by the lowering cam. There was a problem in that unnecessary wear occurred on the contact surface with the butt.

(Means for Solving the Problems) The present invention for solving the problems in the conventional techniques described above provides front and rear knitting passages and rear non-knitting passages between a pair of left and right knitting cams. ,
An auxiliary knitting cam that can be switched forward and backward is provided on the rear outside of the knitting cam, and on the outside of the auxiliary knitting cam,

It is designed to be able to rotate backwards against means. Further, the rear swing cam 12 is rotatable about its support shaft toward the central front fixed cam 6 against an elastic means (not shown) (see the two-dot chain line in the figure).

With the above cam arrangement, the butt of the knitting needle introduced between the front partition wall 3 and the middle partition wall 5 in front of one knitting cam 8 can be moved between the front partition wall 3 and the central front fixed cam 6, A front knitting path A is formed between the fixed cam 6 and the other intermediate partition wall 5, and between the other rear swing cam 12 and the knitting cam 8 and the auxiliary retraction cam 9. The butt of the knitting needle introduced between the middle partition wall 5 A rear knitting passage B is formed to guide the knitting needles along a path between the fixed cam 7 and the other auxiliary retraction cam 9, and yarn is fed from the front yarn opening 13 of the carriage 1 to the knitting needles guided in the front knitting passage A. By feeding yarn from the rear yarn opening 14 of the carriage 1 to the knitting needles guided in the rear knitting path B, two-color simultaneous knitting can be performed.

Also, the butts of the knitting needles introduced between one knitting cam 8 and the rear partition wall 4 are placed between the rear partition wall 4 and the tack cam 10, between the rear partition wall 4 and the central rear fixed cam 7, and between the rear partition wall 4 and the central rear fixed cam 7. Between the partition wall 4 and the other tack cam 10,
A rear non-knitted passage C is also formed which guides along a path between the rear partition wall 4 and the other knitted cam 8.

An auxiliary knitting cam 15 is supported by a support shaft on the outside of the rear part of the knitting cam 8, and can be switched back and forth. This auxiliary knitting cam 15 can be rotated forward in the rear position against elastic means (not shown) (see the two-dot chain line in the figure).

An outer fixed cam 16 located between the front partition wall 3 and the rear partition wall 4 is fixed to the outside of the auxiliary cam 15, and between the fixed cam 16 and the front partition wall 3, the A front guide passage D is formed which leads to the front knitting passage A and which guides the butt of the knitting needle at the position just before the knitting needle is removed in substantially the same position. A rear guide path E is formed that guides the butt of the knitting needle in the position substantially as it is.

When the auxiliary knitting cam 15 is in the rear position, the butts of the knitting needles in the knitting preparation position (the hooks of the knitting needles are located behind the comb tooth row) introduced from one side along the rear guide path E are moved forward. The auxiliary knitting cam 1 is guided to the rear knitting path B, and the auxiliary knitting cam 1
5 is in the front position, the butts of the knitting needles introduced from one side along the rear guide path E are retreated and guided to the rear non-knit path C.

At the inner end of the outer fixed cam 16 (the end on the side of the knitting cam 8), a forward cam 17 is supported by a spindle for slightly advancing the butt of the knitting needle after passing through the rear end of the knitting cam 8 and completing knitting. .

The forward cam 1 is disposed on the front side of the outer fixed cam 16.
A lowering cam 18 for lowering the butt of the knitting needle advanced in step 7 is provided, and the lowering cam 1
A needle selection cam 19 is arranged outside of the needle selection cam 8 .

The needle selection cam 19 constitutes a needle selection member in cooperation with the reduction cam 18, and knits needles that have been reduced by the reduction cam 18 and selected to the reduction position by a selection locking member (not shown) in the needle bed. The butts of the knitting needles are sorted into the forward guide path D and set at the needle selection position (the stitch is suspended above the open latch), and the butts of the knitting needles that are not selected to the lowered position by the selection member and returned to the upper position is sorted into the rear guide path E and set as the formation preparation position. In other words, the sorting member is located in the rear guide passage E.
The butts of the knitting needles introduced from the front are sorted into two groups, front and rear, and the butts of the front knitting needles are sent to the front guide path D.
The butts of the rear knitting needles are each guided to the rear guide path E.

A guide cam 20 is disposed at the outer end of the outer fixed cam 16 to prevent reverse entry from the rear guide passage E to the lowering cam 18. Guide cam 20
is expanded by the butt of the selected rear knitting needle against the elasticity of the elastic means,
The bat is allowed to pass through the rear guide passage E (double-dashed chain line in the figure).

A horizontally long partition wall 21 is provided between the lowering cam 18 of the needle selection member and the front guide passage D along the direction of the guide passage D.

A fixed guide cam 22 is disposed between the inner side of the partition wall 21 and the knitting cam 8, and between the guide cam 22 and the partition wall 21, the butt of the knitting needles from the front guide path D is guided to the auxiliary knitting cam 15. A communication passage F is formed which introduces the butts of knitting needles after knitting to the front guide passage D from between the auxiliary knitting cam 15 and the rear partition wall 4.

A front switching cam 23 located on the front side of the communication passage F is arranged on the fixed guide cam 22. The front switching cam 23 opens and closes the front end of the communication passage F by rotating around a support shaft, that is, closes or opens the inner end of the front guide passage D, When D is closed (when communication passage F is opened), the butts of knitting needles in front guide passage D before knitting are guided to said communication passage F.

A rear switching cam 24 located on the rear side of the communication passage F is arranged at the inner end of the partition wall 21.
The rear switching cam 24 opens and closes the rear end of the communication passage F by rotating around a support shaft, that is, closes or opens the inner end of the rear guide passage E, and controls the guide. When the passage E is closed (when the communication passage F is opened), the butts of the knitting needles after knitting in the rear guide passage E can be guided to the communication passage F.

A bellow removal cam 25 is arranged in front of the needle selection cam 19 of the needle selection member. Bela slip-off cam 25 is
The butt of the knitting needle introduced through the communication passage F is placed in front of the needle selection member (the lowering cam 18 and the needle selection cam 19) at the slip-off position (the position where the stitch leaves from above the open latch backwards). A rear position where the knitting needle is advanced forward and a front position where the knitting needle is passed through the needle selection position (referring to the position passing through the front guide path D along the front side of the partition wall 21) behind the collar removal position can be taken. (See the two-dot chain line in the figure).

A retraction cam 26 is arranged outside the tongue removal cam 25. The retraction cam 26 is the bellow removal cam 2.
The butt of the knitting needle, which has been advanced to the flattening position by step 5, is retreated to the needle selection position (front guide path D). When the knitting needles move back, the latch does not close due to the loose stitches.

A one-way switching cam 27 located behind the forward cam 17 is provided on the rear bulkhead 4 so as to project into the rear guide passage E only when the forward cam 17 is in the rear position. The butts of the knitting needles are allowed to pass through the passage E, and the butts of the knitting needles that have passed between the rear switching cam 24 and the rear partition wall 4 are guided to the forward cam 17 to reach the needle selection member.

Further, the various movable cams mentioned above are adapted to be switched in relation to each other by appropriate switching means (not shown) depending on whether the two-color simultaneous knitting or the argyle knitting is required.

In the above-described carriage for a hand knitting machine, when performing two-color simultaneous knitting, the cam arrangement is used as shown by the solid line in FIG. In this state, as the carriage slides, the butts of the knitting needles are sorted into the needle selection position (referring to the position passing through the front guide path D) and the knitting preparation position (referring to the position passing through the rear guide path E). are introduced into the front knitting passage A and the rear knitting passage B, respectively, and both the front and rear yarn openings 13 and 1 are introduced along the way.
The yarn is fed from 4, and two-color simultaneous knitting is performed.
After completion of knitting, the butts of the knitting needles are sorted back and forth by the other needle selection member and guided to the needle selection position and the knitting preparation position. In FIG. 1, a dotted line X indicates the passage of the butt of the knitting needle at the needle selection position, and a dotted line Y indicates the passage of the butt of the knitting needle at the knitting preparation position.

Next, even when the carriage 1 is turned back and slid, the same knitting as described above is performed.

Further, when performing argyle knitting, the cam arrangement is as shown by the solid line in FIG. 2, and the butts of the knitting needles that have been left in the flat state are all placed at the needle selection position. However, before sliding carriage 1,
The knitting yarn on the hook of a certain required range of the knitting needle group at the needle selection position is wrapped around different knitting yarns on the hooks of each of the other required ranges. and,
By sliding the carriage 1, the butts of each of the knitting needles are introduced by bouncing off the flattening cam 25, and then changed to the rear by the front switching cam 23, passing through the communication passage F, and being knitted by the auxiliary knitting cam 15. It is retracted to the over position and a knitting action is performed. After the knitting is completed, the butts of the knitting needles pass through the rear non-knitting path C, and all of them pass through the rear switching cam 2.
4, passes through the communication passage F, is further advanced by the bellow removal cam 25, and is then moved forward by the retracting cam 2.
6, and is guided to the needle selection position.
Therefore, the butts of the knitting needles are guided to the needle selection position without being subjected to the selection action by the needle selection member. In addition, the passage path of the butt of the knitting needle in the case of argyle knitting is shown by a dashed line Z in the figure.

In order to perform the next course of argyle knitting, each knitting yarn is wound around the knitting needle group guided to the needle selection position in the manner described above, and then the carriage 1 is turned back and slid in the opposite direction. Then, the same organization as above will be made.

(Effect of the invention) In other words, the gist of the invention is the configuration described in the column of "Means for solving the problems" mentioned above, and the positional relationship between the front and rear of the tongue removal cam, the retraction cam, and the needle selection member is changed. Because it is arranged side by side, compared to the conventional needle selection member, bellow removal cam, and retraction cam arranged in series on the left and right,
This has the effect of reducing the length of the carriage in the left and right direction, thereby making the carriage more compact.

In addition, in the case of argyle knitting, after knitting is completed, the butt of the needle selection in the rear guide path is guided along a path mainly formed by the rear switching cam, front switching cam, and lug removal cam. The butt of the knitting needle is led out from the front guide passage through the communication passage, and the butt of the knitting needle is not subjected to the needle selection action by the needle selection member, but the butt of the knitting needle is performed by the collar removal cam. This has the effect that it is possible to prevent the noise that would occur in the conventional device where the needle was subjected to unnecessary needle selection action, as well as the wear and tear on the contact surface between the lowering cam and the butt. In particular, a horizontally long partition wall extending in the direction of the passageway and having an inner end facing the communication passageway is provided between the needle selection member and the front guide passage, and the partition wall has a partition wall for opening and closing the rear guide passageway. In addition, by supporting a rear switching cam that introduces the butt of the knitting needle in that passage into the communication passage when closed, the carriage can perform both argyle knitting and two-color simultaneous knitting. In addition, the butts of knitting needles are not subjected to unnecessary needle selection action during argyle knitting, which is beneficial in preventing noise and wear.
