Description

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

(Prior Art) Various types of set-up devices have been proposed in the past, and methods have also been developed for holding the knitted fabric between clamping members and pulling it downward.

(Problem to be solved by the invention) In this type of knitting machine in which the front and rear needle beds are arranged in a mountain shape, the knitted fabric pull-down device is installed in a narrow space because the conventional pull-down mechanism is relatively complicated. As a result of this particular restriction, it has been necessary to provide the sinker at a wide position considerably below the sinker opening at the tip of the needle bed facing the chevron.

Therefore, when pulling the knitted fabric downward at the lower position, the knitted fabric must be pulled at a lower position that is separated by a considerable length, that is, at least ten or more knitting courses from the knitting section, before reaching the pull-down operation position. In this case, the traction only stretches the stitches of the drooping knitted fabric, and the traction force disappears, and the traction force does not reach the knitted part, especially when the drooping knitted fabric includes a knitted fabric with a narrow knitting width or the number of stitches. When the number of knitted fabrics increases rapidly, the problem is that even if the knitted fabric is pulled at a position 10 or more steps below, it only pulls and tightens the narrow knitted fabric part, and no traction force is applied to the wide part continuing above. It was hot.

The present invention aims to eliminate such conventional disadvantages.

(Means for Solving the Problems) In order to achieve the above object, the present invention eliminates the conventional disadvantages by providing a knitted fabric pull-down device at a lower position as close as possible to the knitting part, and a chevron shape. Directly below the sinker opening at the tip of the front and rear needle beds facing the front and rear needle beds, rotating rods with cross-sections with different diameters other than circular are formed at both ends and at multiple positions in the middle of the rod for pivot support.A small-diameter shaft portion with a circular cross section. is placed above the extension line of the bottom of the needle bed so as to be freely rotatable, and a suppression plate is elastically pressed against one side of the needle bed in the longitudinal direction, and the rotation of the rotation rod allows the needle to be moved between the pressure plate and the suppression member. It is characterized in that the knitted fabric immediately after knitting is pinched and guided downward.

(Function) The set-up device according to the present invention includes a rotating rod 4 having a non-circular cross-section so that it can be installed as close to the lower part of the knitting section as possible, at both ends of the rod 4 and at a plurality of intermediate portions. The rotating rod 4 is rotatably supported by a circular small-diameter shaft portion 4a formed at a position above the extension line of the bottom of the needle bed. Therefore, the distance between the knitting section and the rotating rod 4 is only 5 or 6 stages of the knitting course, and therefore the traction operation due to the clamping between the rotating rod 4 and the suppressing member pressed against it is not possible. It can be applied to the knitting section reliably.

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

In the drawings, reference numerals 1 and 1 indicate front and rear needle beds that face each other in a chevron shape, and reference numerals 2 and 2 indicate sinker forming members that form sinker openings 3 at the tips of each needle bed 1.

Directly below the sinker opening 3, both needle beds 1, 1
A rotating rod 4 having a cross section other than circular, such as a polygonal or elliptical cross section having different diameters, is installed along the length direction of the needle bed 1 at the uppermost position within the interval 1a formed by the needle bed 1.

That is, the rotating rod 4 is formed with circular small-diameter shaft portions 4a for pivotal support at both ends and at a plurality of positions in the middle. The small-diameter shaft portion 4a is rotatably supported by a bifurcated support portion 11 formed on an appropriate one of the many members 2 forming the sinker opening 3, and the supporting position of the small-diameter shaft portion 4a is A pulley 5 is fixed to one end of the rotating rod 4 at a position above the extension line of the bottom surface of the needle bed 1, for example, the center position of the circular small diameter shaft portion 4a is within about 2 cm from the bottom surface of the needle groove of the needle bed 1,
The rotary rod 4 is rotated in the direction of the arrow in FIG. 2 via a belt mechanism 7 from a drive pulley 6' that is linked to a motor 6 installed below, and a supporting rod is placed below the rotary rod 4 in parallel with this. 8 is fixedly installed, and the tip of a suppression plate 9 attached to the support rod 8 is elastically pressed against one side of the rotation rod 4. In the illustrated example, a leaf spring 10 is connected to the tip of the suppression plate 9. and brought it into contact with the rotating rod 4.

The suppression plate 9 is divided into strips of appropriate width in the length direction of the rotating rod 4, and a leaf spring 1 is attached to the tip of each strip.
0 was added.

(Effects of the Invention) According to the present invention, the knitted fabric is guided downward by being held between the rotating rod and the suppressing plate elastically pressed against the rotating rod, thereby preventing the stitches from becoming irregular after knitting. The rotary rod that performs the downward pulling operation is located directly below the sinker opening, and the circular small diameter shaft portion formed as a shaft support of the rotary rod within the interval between both needle beds is particularly positioned from the extension line of the bottom surface of the needle bed. By being pivoted at a lower position as close as possible to the knitting part as an upper position, and by making the cross-sectional shape of the rotating rod a different diameter cross-section other than circular, the rotation and the elasticity of the suppressing member Since the knitted fabric is caught immediately after being knitted, the traction action does not affect the knitted part, unlike the conventional method where the knitted fabric that has finished knitting and has a relatively long droop is caught and pulled at a position below the knitted fabric. For this reason, it is possible to reliably eliminate imperfections in the preparation of the stitches and obtain a high-quality knitted fabric, and its structure is extremely simple. Although a knitted fabric pull-down jig is hung on the knitted fabric, this can be omitted, and the use of a presser that presses the stitches from above during knitting can be omitted.

[Claims] 1 Immediately below the sinker opening at the tip of the front and rear needle beds facing each other in a chevron shape, a rotating rod with a cross section with a different diameter other than circular is formed at both ends and at multiple positions in the middle of the rod for pivot support. The shaft is positioned above the extension line of the bottom of the needle bed so that it can rotate freely, and a suppression plate is elastically pressed against one side of the shaft in the longitudinal direction, so that the rotation of the rotation rod allows the rotation of the shaft to rotate freely.
