Embodiment 1

[0066] figure 1 As Example 1, the schematic configuration and operation of the flatbed knitting machine 1 including the movable sinker 10 is shown. figure 1 (a) is shown in the closed state, figure 1 (b) is shown in the open state. The flat knitting machine 1 is formed by arranging a needle bed 3 on a base 4 and arranging a needle plate 5 in order to knit a knitted fabric on the nip 2 side. In a direction perpendicular to the paper surface, needle grooves are formed between the needle plates 5 arranged at a certain pitch, and knitting needles such as latch needles and compound needles are accommodated. The base 4 and the needle plate 5 are positioned by the wire rope 6 penetrating in the direction perpendicular to the paper surface. A sinker guide groove 4 a is provided at the front end of the base 4 facing the gap 2 .

[0067] The movable sinker 10 includes a sinker 11 and a torsion spring 12 . Among them, the sinker 11 and the torsion spring 12 are integrated. A plural...

Embodiment 2

[0083] Figure 4 As Example 2, the schematic configuration and operation of the flatbed knitting machine 21 including the movable sinker 30 are shown. Figure 4 (a) is shown in the closed state, Figure 4 (b) is shown in the open state. In this embodiment, the actuated arm 31c of the sinker 31 is branched from between the action arm 31b and the support portion 31a, and protrudes above the needle plate 25 . The front end 32a of the torque spring 32 protrudes above the needle plate 25 at a position rearward of the actuated arm 31c. The needle plate 25 forms the needle bed 23 together with the base 24 , and the direction in which the actuated arm 31 c and the front end 32 a of the torque spring 32 protrude is outside the needle bed 32 .

[0084] The sinker cam is accommodated in the opening and closing cam surface 34a of the opening and closing control cam 34 and the torsion spring control cam as two butts protruding from the needle bed 33 as the front end of the receiving arm...

Abstract

[Problem to be solved] To provide a flatbed knitting machine equipped with movable sinkers, which can prevent increase in stress amplitude of a torque spring when the sinkers are opened and closed even when the movable sinkers are controlled directly by a sinker cam mounted on a carriage. [Solution] A biasing cam surface 13a presses a leading end 12a of a torque spring 12 of which base end 12b is set to a portion between a support receive part 11a and a function arm 11b of a sinker 11 so as to bias the sinker 11 through the torque spring 12. The pressing force can be weakened in an opened state even when it is strengthened in a closed state. A stress of the torque spring 12 in the opened state also does not become larger than that in the closed state, so that an increase in the stress amplitude of the torque spring 12 is prevented when the sinker is opened and closed even with each movable sinker 10 controlled directly by the sinker cam mounted on the carriage.

Description

technical field [0001] The present invention relates to a flatbed knitting machine provided with a movable sinker capable of pressing down a knitted fabric. Background technique [0002] Conventionally, there has been known a technique in which a knitting needle and a sinker for forming stitches in the gap are directly operated by the sinker cam mounted on the cam carriage on the flat knitting machine, so that the opening and closing can be performed (for example, refer to Patent Documents 1 and 2). ). Such a movable sinker has a support portion that is supported in a swingable and displaceable manner near the gap of the needle bed, an action arm that extends from the support portion to the gap side, and a receiving portion that extends from the support portion to a side away from the gap. boom. The support portion has an arc shape, fits into a support portion recessed into an arc shape provided on the needle bed side, and is supported in a swingable state with the center ...
