Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a carriage for a hand knitting machine that is capable of argyle stitching.

[Conventional technology]

Conventionally, as this type of carriage, there is one shown in, for example, Japanese Utility Model Application Publication No. 53-56059.
That is, in this thing, a switching cam and a flattening cam, each of which can be placed in two positions, are pivotally mounted on the outside of the knitting cam so that their respective tips face inward. A manually operable lever whose intermediate portion is rotatably supported around a uniaxial line is provided between the switching cam and the bellow removal cam, and a spring is applied to the switching cam and the tongue removal cam, and a lever is provided at each tip thereof. The pin is always in pressure contact with the lever. By placing the lever at one end of its rotation, the switching cam is placed at the front position and the tongue release cam is placed at the rear position, making it possible to perform argyle twisting. By placing the switching cam at the other end of the rotation, the switching cam is placed at the rear position and the tongue removal cam is placed at the front position, making it possible to knit a flat thread other than argyle thread. .

[The problem that the idea aims to solve]

However, according to the conventional method, the arrangement of the switching cam and the tongue removal cam is determined in advance in the case of the argyle net and flat net knitting, as described above. When switching from one formation to the other or vice versa, it is necessary to manually operate the lever to change the arrangement of the switching cam and the tongue removal cam, which makes the operations for the various formations complicated. Furthermore, if the switching operation is forgotten, there are drawbacks such as a predetermined knitting being impossible.

However, the present invention automatically moves a pair of swing cams placed between a pair of left and right knitting cams to a predetermined position by utilizing the collision effect with the butt of a knitting needle, regardless of whether knitting is performed in both types. By making it possible to switch the double-swing cam to the position shown in FIG. The purpose of the present invention is to provide a carriage for a hand knitting machine capable of producing a desired argyle thread.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a butt passage for guiding the butts of knitting needles between the front side parts of a pair of left and right main knitting cams, and also provides a butt passage for guiding the butts of knitting needles between the butt passage and each main knitting cam. A pair of left and right swinging cams are provided that are supported so as to be swingable back and forth so that their ends cross the butt passage in the front-back direction, and are rotatable around a vertical axis between the pair of swinging cams. A conversion lever is provided, and the conversion lever and the pair of swing cams are fitted and connected through a connecting hole and a pin, and the pair of swing cams are connected to each other in a seesaw manner, and during normal flat knitting. When the swing cam on the front side in the carriage movement direction collides with the butt of the knitting needle that is moving backward towards the butt path and is swung to the rear position, the swing cam on the rear side in the carriage movement direction is swung to the rear position through rotation of the conversion lever. The cam is swung to the forward position, and the swing cam switched to the forward position guides the butts of the knitting needles in the butt passage toward the knitting main cam on the rear side in the carriage movement direction, and when knitting argyle net, When the swing cam on the front side in the carriage movement direction collides with the butt and is swung to the front position, the swing cam on the rear side in the carriage movement direction is swung to the rear position through rotation of the conversion lever, and then The butts of the knitting needles in the butt passage are moved toward the front of the main knitting cam on the rear side in the carriage movement direction by the swinging cams switched to the horizontal position, and further, the swinging cams A pair of swing cams are placed on the lower surfaces of the carriage on the front and rear sides between the carriages, and when the pair of swing cams swing to the forward or rear positions, the swing cams come into contact with the respective inner ends of the swing cams to restrict the swing.
In addition, front and rear elastic regulating members made of an elastic body such as rubber are provided.

[Effect]

According to the above means, during normal flat formation,
The swing cam on the front side in the carriage movement direction collides with the butt of the knitting needle that is moving backward toward the butt path, and is swung to the rear position by the butt. The conversion lever is rotated in conjunction with the swinging of the swinging cam, and the swinging cam on the rear side in the carriage sliding direction is swinged to the forward position. Therefore, the butt of the knitting needle is guided to the main knitting cam at the rear in the sliding direction of the carriage. Also,
During argyle stitch knitting, the swing cam on the front side in the carriage movement direction collides with the butt of the knitting needle moving forward toward the butt path, and is swung to the forward position by the butt. The conversion lever is rotated in conjunction with the swinging of the swinging cam, and the swinging cam on the rear side in the carriage sliding direction is swinged to the rear position. Therefore, the butt of the knitting needle is advanced to the front of the main knitting cam on the rear side in the sliding direction of the carriage beyond the flattening position. In any of the configurations described above, when the double-swiveling cam is switched in arrangement, its inner end portions come into contact with the front and rear elastic regulating members, and the rotational position thereof is regulated.

[Effect of idea]

As detailed above, this invention provides a pair of swing cams for argyle netting between a pair of left and right knitting main cams, and rotates around a vertical axis between the pair of swing cams. The converting lever and the pair of swing cams are fitted and connected by a connecting hole and a pin, so that the swing cam on the front side in the carriage movement direction collides with the butt of the knitting needle and moves to the front or rear position. When swinging, the swing cam on the rear side in the carriage movement direction swings to the rear or front position through the rotation of the conversion lever, and the pair of swing cams are configured to interlock with each other in a seesaw manner. In both cases of normal flat knitting and argyle knitting, the butts of the knitting needles introduced toward the butt passage are brought into direct contact with the swinging cams, and the double swinging cams are used to utilize the abutting action. The arrangement of the double-swiveling cams can be automatically switched, and there is no need to manually switch the arrangement of the double-swiveling cams in advance as in the conventional system mentioned at the beginning. Therefore, since this switching operation is unnecessary,
Preparation operations for each formation become easier, and each formation can be performed without error. Further, the front and rear elastic regulating members can prevent shocks, noises, etc. caused by switching the arrangement of the double-swing cams.
