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) It has already been possible to pull a knitted fabric downward by installing a pulling device consisting of a rotating rod and a suppressing member in pressure contact with the rotating rod in the space between the front and rear needle beds facing each other in the shape of a chevron. Although it is being done,
The rotating rod that goes into the device needs to be installed at least along the entire length of the needle bed. Therefore, if there is a pivot at both ends, a deflection will occur in the middle of the rotating rod, causing damage to the knitted fabric. This causes inconvenience in lowering the amount. For this reason, when the diameter of the rotating rod is increased to prevent the occurrence of 1-stroke, the pulling mechanism will be large due to the suppression member that presses against it, so these equipment must be installed inside the chevron-shaped space of the U floor. Since it is impossible to place the equipment above the gap between the sinkers, the lower blade position must be located far away from the gap between the sinkers. In the J3 knitted fabric in between, the stitches are easily distorted due to free slack, and if there is a part with a small line width during knitting, the small and medium parts are pulled when pulling down [However, the traction force at both ends falling to the large and medium part is This results in defects such as unevenness of the action u1' stitches, and it is necessary to knit an extra loose knitted part in the knitted fabric,
No other proposal was made other than using a fixed frame to support the middle of the rotating rod.

(Problems to be Solved by the Invention) It is desirable to pull down the knitted fabric as close to the knitting section as possible to pull the knitted fabric immediately after it has been knitted, but in the conventional technology, the device is large. It was difficult to install the equipment in the narrow space at the top because of the intermediate shaft support of the rotating rod.

(Means for Solving the Problems) The present invention makes the knitted fabric pull-down device as small as possible! Dojite ε
The rotating rod has a small diameter so that it can be installed as high as possible within the space between floors, and the small diameter prevents bending in the middle of the rotating rod, making it compatible with miniaturization. In this proposal, a rotating rod is installed along the length direction of the 11 beds at the upper part of the opposing gap between the two needle beds, directly below the L1 section between the tip sinkers of the front and rear needle beds that are opposed to each other in a chevron shape. A device is constructed in which a suppression member is pressed against one side in the longitudinal direction of the structure, and the knitted fabric held between the suppression member and the suppression member is pulled downward by the rotation of a rotating rod. The intermediate portion of the rotating rod is rotatably supported at a proper location by a bearing portion that is integrally formed with the sinker forming metal fitting.

(Example) In the drawings, (1) (1) is an 11 bed with a sinker opening (3) formed at the tip of the chevron, and the sinker opening (3) is on both sides! It was formed by sinker forming metal fittings (2) attached at predetermined gauge intervals along the leading edge of one bed (1).

Both sensudoko (1) (1) form a mountain-shaped interval (4)
A rotating +1 (5) is installed in the lengthwise direction of the U-bed (1), and a suppressing member (6) is pressed against one side of the U-bed (1) in the lengthwise direction. The knitted fabric a is successively held between the rotating rod (5) and the suppressing member (6), and the knitted fabric a is pulled downward by rotation of the rotating rod (5).

The above-mentioned pull-down device should be placed as close as possible to the upper part of the chevron-shaped gap (4) formed by the two needle beds (1) directly below the sinker opening (3), that is, as close as possible to the knitted part of the knitted fabric. Since it is desirable to make the rod as compact as possible, the rotating rod (5) must also have a small diameter, so if it is long, simply supporting it at both ends will cause flexure in the middle. This causes an inconvenience in the contact pressure with the suppressing member (6), which impairs the traction of the knitted fabric, and therefore, the intermediate portion of the rotating rod (5) must be supported μ°.

However, the chevron-shaped space (4) becomes narrower in proportion to the culm toward the top, making it difficult to install the shaft support.

The present invention provides intermediate support for the rotating rod (5) adapted to the conditions of the installation position of the rotating rod (5) as described above. The above-mentioned conditions were met by forming the support part on the inside of the rotary rod (5), and @II receiving parts (5a) with a circular cross section were formed at a suitable location in the middle of the rotating rod (5), and a large number of them were arranged. Sinker forming metal fittings (
A bifurcated, substantially semicircular bearing portion (2a) for rotatably supporting the support portion (5a) was integrally formed on the appropriate one of 2). In the illustrated embodiment, the rotating rod (5) has a rectangular cross-section, but its cross-sectional shape may be circular, oval, polygonal, etc. It is installed in the fixed machine frame and rotatably supported by an IC bearing (7).
A drive pulley (IG) is connected to a pulley (8) fixed to one end of the shaft (5) by a motor (9) installed below the pulley (8).

) was supported.

In addition, in the illustrated example, the restrainer 1 [member (6) is rotatable and is provided parallel to the lower part of the 1st eye 1 (5), and is attached to the strip (6a) attached to the Ic axis rod (+2) and its tip. It was formed by the attached leaf spring (611), and the leaf spring (6b) was pressed against the rotating rod (5).

(Function) In the above configuration, the knitted fabric a knitted in the sinker opening (3) is immediately guided between the lower rotating rod (5) and the suppressing member (6) which is in pressure contact with the rotating rod ( 6) is pulled downward, thus preventing the knitted fabric a immediately after knitting from shrinking and becoming irregular due to shrinkage of the yarn or the like.

(Effects of the Invention) According to the present invention, the sinker forming metal fitting that forms the sinker opening is provided with a bearing portion that rotatably supports the middle of the rotation 11 for the knitted fabric pulling device. The movable rod can be supported by the target (1) at the upper position within the chevron-shaped interval formed by the front and rear mounting beds, which prevents deflection of the intermediate portion of the small diameter rotary rod and improves the traction action of the knitted fabric. In this way, the installation position of the pulling device is set as close to the knitting section as possible to pull the knitted fabric immediately after knitting, and to achieve the effect of stabilizing the support of the rotating rod.
