Embodiment Construction

[0056] The structure of the main part of the fastener stringer continuous manufacturing machine of this invention is demonstrated.

[0057] Such as figure 1 As shown, the zipper stringer continuous manufacturing machine of the present invention has: a forming implantation part 1 for engaging elements; a feeder of the engaging element metal wire W that is intermittently fed to the forming implanting part 1 The apparatus 10; the fastener tape supply device 20 for intermittently supplying the fastener tape T to the above-mentioned molded implant part 1 by sending out the fastener stringer S; and the main shaft 30 rotationally driven by a motor.

[0058] Such as figure 2 As shown, the metal wire W for engaging elements is a vertically long material having a head WH and a pair of legs WL, and has a substantially Y-shaped cross section.

[0059] Such as figure 1 and Figure 6 As shown, the forming implant part 1 of the above-mentioned engaging element has: a cutting device, whi...

Abstract

The invention relates to a main shaft anti-reversal device in a zipper teeth chain continuous making machine, which can prevent the reversal of a main shaft when the main shaft stops. A rotary body is arranged on the main shaft (30) which enables each device to work, a ratchet wheel (53) is arranged opposite to the rotary body in a non-rotational manner, the rotary body is provided with a pawl (54), the claw (54a) of the pawl (54) is fixedly clamped on a gear (53a) of the ratchet wheel (53) by a spring to prevent the reversal of the main shaft (30), the pawl (54) resists the spring (55) by the centrifugal force of the rotation of the rotary body to enable the claw (54a) to separate from the gear (53a) and prevent the damage and the abrasion of the claw (54a) when the main shaft (30) rotates, and metal sound can not be generated.

Description

technical field [0001] The present invention relates to a main shaft anti-rotation preventing device in a zipper fastener stringer continuous manufacturing machine. The main shaft anti-rotation preventing device prevents the main shaft from rotating in the opposite direction to that during operation when the main shaft is stopped. Background technique [0002] Conventionally, as a fastener stringer continuous manufacturing machine, as disclosed in Patent Document 1, there is known a fastener stringer continuous manufacturing machine having a forming implantation portion of an engaging element, an intermittent A feeding device for the metal wire for engaging elements that is fed to the forming implant part, a fastener tape feeding device that intermittently feeds the fastener tape to the forming implant by feeding out the fastener stringer, etc. [0003] As the above-mentioned metal wire for engaging elements, a long metal wire having a circular cross-section is formed by a p...
