Circular braiding machine

Abstract

The invention provides a torchon lace machine which halves impact noises produced on the energizing of a solenoid and can always accurately perform patterning. This torchon lace machine is characterized by disposing a clutch 9 for connecting a rotor metal 1 to a rotor-driving shaft 6, when upward moved, and separating the rotor metal 1 from the rotor-driving shaft 6, when downward moved, a fork member 12 which holds the clutch and is downward energized with a spring 13a, a slide shaft 14 horizontally slidably penetrating the back plate of the fork member , the first cam 15a which acts on a cam follower 14a disposed on the inner end side of the slide shaft to upward displace the fork member through the slide shaft, a solenoid for pushing the slide shaft to make the cam follower to approach the operation area of the first cam, the second cam 15b for pushing back the cam follower to the outside of the operation area of the first cam, and the third cam 19 for reinforcing the force of the spring for downward energizing the fork member. Patterning can always accurately be carried out by the operation of the third cam 19.

Description

technical field [0001] The present invention relates to a circular knitting machine (トションレスス machine) that simplifies the structure of the clutch mechanism of the rotor metal part and the rotor drive shaft, reduces the impact sound during clutching by half, and can accurately perform jacquard. Background technique [0002] Circular knitting machines generally use the rotation (every 180 degrees) of multiple (64, 94, etc.) rotor metal parts arranged in the annular direction to make the bobbin rotate along the circumferential direction, and the The yarn pulled out from the bobbin is collected in the beating part arranged in the center of the ring to make a pattern (pattern). After beating, the yarn is sequentially wound on the winding drum through the nip roller. [0003] A plurality of rotor metal parts are overlapped and loosely fitted on the rotor drive shaft, which has been loosely fitted on the lower part of a predetermined number of fixed shafts that are equally divided ...

AI Technical Summary

Problems solved by technology

[0007] However, the circular knitting machine of the new proposal operates when the solenoid is energized to pull the sliding shaft, so there is a problem that impact sounds are generated intermittently with the sliding of the solenoid core (plunger core)

In addition, when the solenoid pulls the core (plunger core) to push back the cam follower outside the action area of ​​the first cam, the fork-shaped part is forced downward due to the action of the spring, but only the spring The elastic force of the rotor is not enough, and the function of each rotor metal part becomes unstable, which has a great impact on the jacquard problem
