Embodiment 1

[0066] figure 1 The schematic structure and operation of the flat knitting machine 1 provided with the movable sinker 10 are shown as Example 1, 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 needle beds 3 on a base 4 and needle plates 5 in order to knit a knitted fabric on the needle bed 2 side. Needle slots are formed between the needle plates 5 arranged at a constant pitch in a direction perpendicular to the paper surface, and accommodate knitting needles such as latch needles and compound needles. The abutment 4 and the needle plate 5 are positioned by a wire rope 6 penetrating in a direction perpendicular to the paper. At the front end of the base 4 facing the tooth gap 2, a sinker guide groove 4a is provided.

[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 plurality of such movabl...

Embodiment 2

[0083] Figure 4 As a second embodiment, the schematic configuration and operation of a flat knitting machine 21 provided with a 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 driven arm 31c of the sinker 31 branches from between the working arm 31b and the support portion 31a, and protrudes above the needle plate 25. As shown in FIG. The front end 32a of the torsion spring 32 protrudes above the needle plate 25 at a position rearward of the driven arm 31c. The needle plate 25 forms the needle bed 23 together with the base 24 , and the direction in which the driven arm 31 c and the tip 32 a of the torsion spring 32 protrude becomes outward of the needle bed 32 .

[0084] The sinker cam uses the front end of the driven arm 31c of the sinker 31 and the front end 32a of the torsion spring 32 as two butts protruding from the needle bed 33, and is accommodated in the opening and closing c...

Abstract

The invention provides 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. 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 flat knitting machine provided with a movable sinker capable of pressing down a knitted fabric. Background technique [0002] Conventionally, the following technical proposals are known: on a flat knitting machine, a sinker cam mounted on a carriage can be used to directly operate the knitting needle and the sinker forming a stitch at the needle bed, thereby enabling opening and closing (for example, refer to Patent Documents 1 and 2). ). This type of movable sinker has a support part that is supported in a swingable and displaceable manner near the tooth bed of the needle bed, an action arm extending from the support part to the tooth bed side, and a receiving arm extending from the support part to the side away from the tooth bed. boom. The support portion is arc-shaped, and is fitted with a recessed arc-shaped support portion provided on the side of the needle bed, and is supported in a swingable state with the c...
