Description

Setting device in flat knitting machine

The present invention relates to a set-up device in a flat knitting machine that can freely remove a set-up yarn from a set-up needle.

The flat knitting machine is provided below the lip of the front and back needle beds. As the set-up part of the knitted fabric, tension is applied to the knitted fabric by pulling down the supplied set-up yarn and the knitting needle is locked. A set-up device for pulling down the knitted fabric is provided until the knitted fabric is clamped by the roller type lowering device so that the stitches that are made do not come off the knitting needle.
Among such set-up devices, for example, a set-up device disclosed in Japanese Patent Publication No. 3-77298 has been proposed as a set-up device that can freely remove a set-up yarn from a set-up needle after the knitted fabric is pulled down.
This set-up device includes a set-up needle 80 formed by combining the slider 81 shown in FIG. 9 and the set-up needle body 82 shown in FIG. 10 as shown in FIGS.

More specifically, the set-up needle 80 is a set-up needle comprising a set-up needle body 82 and a slider 81 slidably combined with the set-up needle body 82 along the longitudinal direction of the set-up needle body 82. The slider 81 has a hook 83 facing forward at its upper end, and an engaging portion 84 for connecting to a lifting mechanism for raising and lowering only the slider 81 at its lower end. On the other hand, the set-up needle body 82 has a vertically extending long groove 85 for slidably receiving the slider 81 along the longitudinal direction, and the set-up needle body 82 with respect to the comb bed (set-up needle working plate).

Engagement portions

86 and 87 are fixed on the rear surface so as to be fixed so as not to move up and down.

Further, the slider 81 is configured to move up and down by a predetermined stroke as a relative positional relationship with the set-up needle body 82 in the long groove 85, and the set-up needle body 82 has a slider at the upper end of the front surface thereof. When 81 is pushed up to the uppermost position in the set-up needle main body 82, the hook 83 of the slider 81 is stored therein, and when the slider 81 is slightly lowered from the uppermost position, the hook 83 of the slider 81 is positioned immediately below the set-up needle main body 82. A forward-facing hook storage projection 88 configured to be exposed from the exposure.

When the set-up yarn 80 is pulled down by the set-up needle 80, first, the set-up needle 80 protrudes from the tooth opening between the front and back needle beds in a state in which the hook 83 of the slider 81 is stored in the hook storage projection 88. And positioned above the set-up yarn fed in the horizontal direction. Next, as shown in FIG. 11, only the slider 81 is slightly lowered to expose the hook 83 below the hook storage projection 88. When the set-up needle 80 is lowered in this state, the set-up yarn is caught by the hook 83, and the set-up yarn can be pulled down. On the other hand, when removing the set-up yarn from the set-up needle 80, the set-up yarn can be detached from the hook 83 by slightly raising the slider 81 and storing the hook 83 in the hook storing projection 88.

However, as shown in FIG. 12, this set-up needle 80 has to form a vertical groove 85 in the set-up needle body 82 for receiving the slider 81 slidably along the longitudinal direction. Forming such a long groove in the set-up needle body 82 that requires toughness has a difficulty in processing and has been a factor of high cost. Further, since the set-up needle 80 employs a method in which the set-up yarn is hooked on the downward hook 83 and pulled downward, the set-up yarn is detached from the hook 83 when the downward tension on the knitted fabric is loosened during knitting. There was a case.
