Embodiment 1

[0060] figure 1 The structure of the knitted fabric pull-down device 21 included in the flat knitting machine 20 according to the first embodiment of the present invention is schematically and simplified shown on one side, for example, the left side. Except for the portion supported by the swing-displaced switch lever, the rotary shaft and the like are rotatably supported at the stationary portion inside the flat knitting machine 20 , but illustration of these support portions is omitted. In the knitted fabric pull-down device 21, the rollers 3, 4 and Figure 7 The rollers 3 and 4 are equivalent, and the switch mechanism for switching between the rollers 3 and 4 is arranged on both sides of the flat knitting machine 20, and its driving part is arranged on the left side. In the figure, the gap between the rollers 3 and 4 is opened. The rotation mechanism for rotating the drive rollers 3 and 4 is arranged on the right side of the flat knitting machine 20 .

Embodiment 2

[0074] Figure 5 The main part of the rotation mechanism 60 as the knitted fabric pull-down device 59 according to the second embodiment of the present invention is simplified and shown in a state between the closed rollers 3 and 4 . The rotation mechanism 60 is disposed on the right side of the flat knitting machine provided with the knitted fabric pull-down device 59 . On the left side of the flat knitting machine, there are Figure 4 same structure.

[0075] The rotation mechanism 60 includes a non-swing side gear 61 , a rotation transmission gear 62 , intermediate gears 63 , 64 , and roller gears 33 , 34 . The non-oscillating side gear 61 is directly mounted on the output shaft of the rotary drive motor 40 . The rotation transmission gear 62 meshes with the non-swing side gear 61, and the teeth on the outer periphery have the same number of teeth. The intermediate gears 63 and 64 have the same shape as the rotation transmission gear 62 , and mesh with the non-swing sid...

Abstract

Disclosed is a flat-knitting machine provided with a fabric pull-down device that can reduce the length and space required to rotationally drive rollers that open and close. The fabric pull-down device (21) is provided with a rotation mechanism (30) which can rotate a roller (3) clockwise and a roller (4) counterclockwise. A rotation transmission gear (32) on the side of the roller (4) is disposed such that the rotational axis thereof lies on the same line as the axis of a pivot shaft (26); thus, even when an opening / closing lever (25) pivots and changes position, a pivoting roller gear (34), which pivots together with the opening / closing lever (25) and moves along a motion trajectory (34a), stays meshed with a non-pivoting gear (31) which does not pivot. When the fabric pull-down device (21) is used, the rollers (3 and 4) rotate at constant speed in opposite directions. Since an Oldham coupling or the like is not necessary, the length and space required to rotationally drive the opening and closing rollers (3 and 4) can be reduced.

Description

technical field [0001] The present invention relates to a flat knitting machine provided with a pull-down device for knitted fabrics. At least a pair of front and rear needle beds face each other across the tooth gaps. As knitting proceeds, the knitted fabric hanging from the tooth gaps is sandwiched between rollers and passed through the rollers. of swivel pull-down knits. Background technique [0002] Conventionally, in a flatbed knitting machine having at least a pair of front and rear needle beds facing each other across the needle bed, a knitted fabric to be knitted hangs down at the needle bed. In order to knit the knitted fabric smoothly, a knitted fabric pull-down device is provided, which needs to forcibly pull the knitted fabric below the tooth gap (for example, refer to Patent Document 1). The knitted fabric pull-down device includes a pair of rollers that rotate so as to sandwich the knitted fabric and pull down. It also has a mouth opening device, which pulls ...
