Description

Detailed Description of the Invention The present invention comprises a main needle bed in which a large number of main knitting needles are arranged in a row, a main carriage that slides on the main needle bed, and a large number of sub knitting needles arranged in parallel in front of the main needle bed. The present invention relates to an improvement of a drawing board type knitting machine equipped with a needle bed and a sub-kissage that slides on the sub-needle bed.

Conventionally, this type of drawing board type knitting machine has been used to knit a so-called drawing board knitting pattern, in which one knitting yarn is knitted by one reciprocating slide of both the main and subcarriages, and knitted with selected knitting needles among the main knitting needles in the waiting position. Yarn is fed to all the knitting needles of the sub-knitting needles in the waiting position and knitting is carried out, and by the next reciprocating movement of both the main and sub-carriages, all the knitting needles of the main knitting needles that were not knitted last time and the sub-knitting needles in the knitting waiting position are knitted. There was a method of knitting by feeding yarn.

In this knitting method, two stitches are made by two back and forth movements of both the main and sub carriages.
Only rows can be knitted, and compared to ordinary rubber knitting, which can knit four rows of stitches in two round trips, the knitting speed is halved, the operations are twice as necessary, and the knitting yarn must be replaced in between. An additional troublesome operation was required.

In the present invention, the main carriage is configured to selectively feed two knitting yarns to each of the main knitting needles at the knitting standby position by sliding in one direction, and the sub-carriage is slid in one direction to selectively feed two knitting yarns to each of the main knitting needles at the knitting standby position. By applying two knitting operations to knit both knitting yarns on the sub knitting needles at the knitting standby position, the knitting pattern on the drawing board can be knitted in one row by sliding both the main and sub carriages in one direction. To provide a drawing board type knitting machine which is capable of knitting the knitting pattern in four stages by forward and backward sliding, at the same speed as normal rubber knitting, and which does not require the troublesome operation of changing knitting yarns. It is something.

Further, the connecting plate 41 is appropriately provided with a brush to prevent the needles of the knitting needles from moving inadvertently.

The operation of the configuration as described above will be explained below.

Place the knitting needles to be knitted on main needle bed 1 in two positions, front and back, 11J.
Then, the front main knitting needle NY and the back main knitting needle NX are used.

A first knitting yarn T is inserted through the first yarn opening 43, and a second knitting yarn U is inserted through the second yarn opening 44.

The cams of both carriages 11 and 30 are arranged as shown in solid lines in FIG.

In this state, both carriages 11.30 are slid in the direction of the arrow a.

First, the front main knitting needles NY are introduced into the second knitting path C-F, and are fed with the second knitting yarn U for knitting.

The rear main knitting needles NX are introduced into the second sliding passage BE and pass through without knitting.

On the other hand, the sub-knitting needle NZ at the knitting standby position is the sub-knitting needle 2nd knitting path Z
-H-K to knit the second knitting yarn U.

Next, the front main knitting needles NY rotate the swinging cam 2T against the elasticity, are guided by the swinging cam 27 to the rear of the second main knitting cam 26, and form a stitch using the second knitting yarn U.

The rear main knitting needles NX rotate the swinging cam 28 against the elastic force, are guided by the swinging cam 28 to the front of the second main knitting cam 26, and are further advanced.

The sub-knitting needle NZ forms a stitch using the second knitting yarn U using the second sub-knitting cam.

The front main knitting needles NY are introduced into the sublimation passage FG and do not knit, and the rear main knitting needles NX are introduced into the knitting passage E-G and are fed with the first knitting yarn T from the first yarn opening 43. knitting needle NZ
is introduced into the auxiliary knitting needle knitting path at -LZ, and the first knitting yarn T is fed thereto.

Thereafter, the rear main knitting needles NX form stitches using the first knitting yarn T using the raw silk cam 12', and the sub knitting needles NZ form stitches using the first knitting yarn T using the sub line cam 31.

Next, the main knitting needles NX and NY are advanced by the needle feed cam 17' and selected back and forth by the needle selection section, and the front knitting needles are guided by the exchange swing cam 27' and guided behind the intermediate cam 24', The cam 28' is pushed open against the elastic direction and moved forward by the rear cam 25', and the front raising cam 2 is moved forward by the rear cam 25'.
2' is pushed open against the elastic direction, placed at the needle selection position (position C), and guided outward, and the rear knitting needles are pushed against the elastic direction by pushing the rear raising cam 23' behind the rear cam 25. It is placed at the formation waiting position (position B) and led out.

The sub-knitting needles NZ push open the sub-raising cam 38' against the elastic force, are placed at the knitting waiting position (Z position), and are led out.

Next, when both the main and sub carriages 11.30 are slid in the direction opposite to the α arrow, the second knitting yarn is hooked onto the second yarn opening 44' and knitted in the same manner as described above, resulting in so-called drawing board knitting. You can organize patterns.

In the above embodiments, the second main knitting section, needle exchange device, and sub knitting needle second knitting passage were installed integrally in the main carriage and the sub carriage, respectively. It is also possible to make only the β portion surrounded by the broken line in , removably attachable to each carriage as an attachment, and to fix it with a screw.

Further, although the knitting yarn to the second yarn opening is changed depending on the direction of movement of the carriage, a known automatically moving yarn opening may also be adopted.

Since the device of the present invention is configured as described above, by simply sliding both the main and sub carriages in one direction, two knitting yarns can be selectively fed to the main knitting needles at the knitting waiting position, and knitting can be carried out. The knitting operation can be applied twice to knit the two knitting yarns to the sub-knitting needles in the standby position, and the knitting pattern on the drawing board can be knitted in one row.
Therefore, the knitting pattern can be knitted in four stages by two reciprocating movements of both the main and subcarriages, so the knitting speed is more than double that of conventional devices, and the troublesome operation of changing knitting yarns is completely unnecessary. The knitting pattern of the drawing board can be knitted with the same operation and speed as knitting ordinary rubber knitting.
