Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a set-up device for pulling downwardly a knitted fabric immediately after being knitted in a horizontal stockinette knitting machine to arrange the stitches.

(Prior art) Conventional set-up devices in which a pressure plate or a pressure roll is brought into contact with a rotating roll and the knitted fabric immediately after knitting is pulled by the pinching pressure are disclosed, for example, in Japanese Patent Application Laid-Open No. 1983-1999.
No. 185851 and No. 185852 are proposed.

(Problems to be Solved by the Invention) In the above-mentioned conventional method, the press plate or the press roll is always in contact with the rotating roll, and therefore it acts effectively on the knitted fabric portion immediately after knitting. In areas other than those immediately after knitting, the stitches were stretched or distorted by traction, resulting in yarn curls and impairing the texture, and the loose yarns hanging down at the ends of the knitting width were wound up, causing other inconveniences.

(Means for Solving the Problems) The present invention eliminates the inconveniences caused by the above-mentioned conventional means, and pulls only the knitted fabric immediately after knitting without damaging the texture. A rotating roll extending in the length direction of the needle bed and a pressing roll parallel to the rotating roll are provided directly below the inside of the tip sinker opening of the front and rear needle beds, and the knitted fabric is held between both rolls, and the pressing roll is The fabric is divided into a number of short rolls in the length direction, and normally each short roll is separated from the rotating roll, and the knitted fabric is divided into a number of short rolls in the length direction, and each short roll is separated from the rotating roll. The knitted fabric sandwiched between the two rolls is pulled downward by pressing only a group of short rolls, the number of which is approximately 1,000, against the rotating rolls in conjunction with the movement of the carriage.

(Function) In the above configuration, during knitting work by the reciprocating movement of the carriage, the knitted fabric width is knitted by the knitting cam group in the short rolls divided into many pieces in the length direction of the needle bed. Only a few short rolls adapt to the movement of the carriage and come into contact with the rotating roll, pulling the knitted fabric sandwiched between both rolls downward in the width of the sandwich, thus including the transfer cam as the carriage moves. The knitted fabric portion immediately after being knitted by the knitting cam group is sequentially pulled to arrange the stitches.

(Example) Embodiments of the device of the present invention will be described with reference to the drawings.

1, 1 is the front and rear needle beds facing each other in a chevron shape, 2 is a carriage that reciprocates along the length direction of the needle bed 1,
The carriage 2 is equipped with a knitting cam 3 including a transfer cam.

A rotary roll 5 is installed along the length of the needle bed, located directly below the inside of the tip sinker opening 4 of both needle beds 1, 1. The roller 5 was driven by a belt so as to be constantly rotated, and the drawing of the roll 5 was made to have a rough surface due to unevenness. In the illustrated example, the rotating roll 5 is constructed by dividing into several pieces in the length direction and connecting them together with a joint piece 6, and a bearing piece 5a is attached at the joint part at an appropriate position in the middle.
to prevent bending due to deflection of the intermediate portion of the roll 5. Reference numeral 9 denotes a pressure roll provided in parallel with the rotary roll 5, and the roll is formed by connecting a large number of short rolls 9a in the axial direction, and each short roll 9a...
is mounted on the tip of a swinging piece 10 whose middle part is rotatably supported on a fixed shaft 11, and its swinging causes the short roll 9a to approach and separate from the rotating roll 5. The roll 9a is held at a position separated from the rotating roll 5 so that the knitted fabric is introduced between the rolls 5 and 9.

In the illustrated example, the swinging of the swinging piece 10 is caused by a shaft piece 12 connected to the lower end of the swinging piece 10, as shown in FIG.
The trochanter 14 of the actuating piece 13 connected to the actuating cam piece 1
5, the swinging piece 10 in which the short roll 9a at the tip is separated from the rotating roll 5 when engaged is swung to bring the short roll 9a into contact with the rotating roll 5, and the trochanter 14 is disengaged from the operating cam piece 15, the swinging piece 10 is automatically returned to its original state and the short roll 9a is separated from the rotating roll 5.

The actuating pieces 13 are each inserted into the shaft piece 12 so as to be able to freely move in the longitudinal direction thereof, and a resilient spring 16 is applied to the insertion part to move the actuating piece 13 at the insertion part to the shaft piece 12. is pressed against the flange piece 12a that is integrated with the
In addition, each actuating piece 13 has its middle inserted into and supported by a fixed shaft rod 17 provided parallel to the fixed shaft 11 so as to be rotated about the shaft rod 17. Lower swing piece 10, shaft piece 1
2. Depending on the weight of the actuating piece 13, trochanter 14, etc.
As shown in the figure, the short roll 9a at the tip of the swinging piece is held in a state separated from the rotating roll 5, and the trochanter 14 of the actuating piece 13 engages with the actuating cam piece 15, and the upper surface thereof When transferred, actuate piece 13
The swinging piece 10 is rotated clockwise while compressing the resilient spring 16 by the clockwise rotation of the roller, and the short roll 9a at the tip is brought into contact with the rotating roll 5.
Therefore, the degree of contact pressure can be adjusted by adjusting the resilient spring 16.

Note that the fixed shaft rod 17 is connected at its intermediate portion by a connecting piece 18 to prevent bending due to flexure of the intermediate portion.

The operating cam piece 15 is attached to a support plate 19 fixed to the carriage 2 so that it can reciprocate integrally with the carriage 2, and its length is determined by the formation cam group including the transfer cam group installed on the carriage 2. The length corresponds to the width of the knitted fabric knitted by No. 3 or slightly longer than that.

Therefore, the actuating cam 15, which moves together with the carriage 2, sequentially acts on a predetermined number of trochanters 14 according to the knitting width, presses the short rolls 9a of each swinging piece 10 against the rotating roll 5, and both The short roll 9a belonging to the trochanter 14, which has separated from the operating cam 15 by pulling the knitted fabric held between the rolls, automatically separates from the rotating roll 5.

(Effects of the Invention) According to the present invention, in a knitted fabric pulling device comprising a rotating roll provided inside the tip sinker opening of the front and rear needle beds and a pressing roll that approaches and separates from the rotating roll, the pressing roll is divided into a number of short rolls. Under normal conditions, each short roll is separated from the rotating roll, and during knitting work by moving the carriage, only the number of short roll groups corresponding to the knitting width of the fabric is moved by the knitting cam group installed on the carriage. is linked to the movement of the carriage and is pressed against the rotating rolls to pull the knitted fabric sandwiched between both rolls downward and arrange the stitches, thereby pulling the knitted fabric in areas other than the areas where both rolls are in contact. This eliminates the problem of poor texture in areas that do not require traction due to constant traction over the entire width of the knitted fabric, as in conventional methods, and traction operations in areas that require traction can be performed by moving the carriage. It automatically changes according to the situation, and has the effect of making its operation precise.
