Knitting yarn gripping device of a flatbed knitting machine, and control method of the same

Abstract

[Object] To provide a knitting yarn gripping device of a flatbed knitting machine which is capable of preventing a yarn break or a yarn cast-off, even when the outer gripping device is lifted, with the inner gripping device in the standby condition while gripping the knitting yarn, and a control method of the same. [Technical Solution] A controller 31 is set so that a standby position of at least the inner gripping mechanism 11a, at which a gripping portion 12a is closed to grip an end of a knitting yarn 6a and is put in standby, is upper in level than a lower limit of a stroke for the gripping portion 11a to move up and down. When the gripping mechanism 11a is first moved down to a position lower in level than the standby position, then is turned around, and then is moved up, the gripping portion 12a is opened. On the other hand, when the gripping mechanism 11a is moved up directly from the standby position, the gripping portion12a is kept in the closed state. Thus, when the outer gripping mechanism 11b is moved up so that the knitting yarn 6b can be caught by the gripping portion 11b, the inner gripping mechanism 11a can also be moved up together, while keeping the condition of the gripping portion 12a that grips the knitting yarn 6a without pulling it, to prevent a yarn break or yarn cast-off.

Description

technical field [0001] The present invention relates to a knitting yarn holding device and a control method thereof for a flat knitting machine which is installed on the side of a needle bed to hold a knitting yarn. Background technique [0002] In the past, in Figure 9 In the flatbed knitting machine 1 shown in simplified form in , at least one pair of needle beds 2 is provided so as to face back and forth across a needle bed 3 . The front ends of the knitting needles (not shown) advance and retreat from the front and rear needle beds 2 to the needle gaps 3, so that knitted fabrics 4 such as pullovers can be continuously knitted while being shaped into a final shape. On the knitting needles of the needle bed 2 , the knitting yarn 6 is supplied to the knitting needles from the yarn feeder 5 that moves above the bed gap 3 . When the use of the knitting yarn 6 for the knitted fabric 4 ends, the yarn feeder 5 is withdrawn to the outside of the needle bed 2 . The knitting yar...
