Description

Technical Field

[0001] The patent of this invention relates to the technical field of rope production and processing equipment, and specifically to a fiber rope twist-free binding equipment. Background Art

[0002] For common fiber rope products, people focus on mechanical performance indicators such as breaking strength and breaking elongation. When using ropes, they are usually unrolled first, especially in mountaineering, rock climbing, rescue, exploration and military applications, and special attention should be paid to the packaging process of ropes.

[0003] Tying is a common packaging method for fiber ropes such as power ropes, static ropes, auxiliary ropes, and hardware ropes. The existing tying method is basically based on manual winding and tying. Each tying will add a certain twist to the rope itself, causing twisting. When the user opens the package, the rope will be twisted. Before use, a "rope-straightening" untwisting process needs to be added, which seriously affects the user experience. At the same time, since the existing tying method relies on workers to manually wind and tie, the labor intensity of the workers is high, the work efficiency is low, the number of workers is large, and the twist cannot be eliminated, and the effect of twist-free tying cannot be achieved. Summary of the invention

[0004] In order to solve the problems existing in the prior art, the patent of the present invention designs a fiber rope twistless tying device which will not twist the rope again during the rope tying process. The tying device includes a pay-off module, a detection module and a tying forming module. The pay-off drum with the fiber rope of the woven package is placed on the pay-off module. The pay-off module is provided with a driving motor to drive the pay-off drum to rotate. The rotation direction of the driving motor is the same as the winding direction of the fiber rope of the package. The detection module includes a tension control wheel and a rope meter; the tying forming module includes a reciprocating wire arrangement device and a rope winding wheel, which are arranged on a common base. A control motor is arranged in the base, and the control motor is connected to the rope winding wheel and drives it to rotate. The fiber rope passes through the tension control wheel and the rope meter and then passes through the reciprocating wire arrangement device, and is finally wound and tied by the rope winding wheel. The rope meter signal is connected to the control motor. When the fiber rope in the pay-off drum is tied by the rope winding wheel, the driving motor and the control motor respectively drive the pay-off drum and the rope winding wheel to rotate synchronously, and the driving motor rotates according to the winding direction of the rolled fiber rope in the pay-off drum, so that the fiber rope is undone and released naturally without twisting; and the rope winding wheel also rotates the rope during the tying process, and twisting will not occur like manual tying.

[0005] Furthermore, the binding and forming module is also provided with a wire breakage automatic stop device, the signal of the wire breakage automatic stop device is connected to the control motor, the control motor adopts a servo motor, the fiber rope passes through the detector of the wire breakage automatic stop device and then is wound on the rope winding wheel through the reciprocating wire arrangement device, when the detector of the wire breakage automatic stop device detects that the fiber rope is broken, it will send a signal to stop the control motor.

[0006] Furthermore, the wire-paying module is provided with a tray, the wire-paying drum is arranged in the tray, a through hole is provided at the bottom center of the tray, a bearing is fixed in the through hole, and the driving shaft of the driving motor passes through the inner ring of the bearing and is connected to the wire-paying drum. The tray supports the wire-paying drum.

[0007] Furthermore, the edge of the upper end surface of the pay-off drum is turned outward to form a flange, so that the rope can be released from the pay-off drum more smoothly without sliding back easily.

[0008] Furthermore, the rope reel includes two inner and outer wheel bodies, the inner and outer wheel bodies pass through their respective center positions through the control motor shaft, wherein the position of the inner wheel body is fixed, and the outer wheel body can slide along the control motor shaft, a fastener is provided at the center of the outer wheel body to position the outer wheel body on the control motor shaft, and the inner and outer wheel bodies are both provided with a plurality of support rods between the center and the outer edge of the wheel body, each support rod of the outer wheel body is provided with a through hole, and a rope reel rod is provided in the through hole, and the rope reel rod passes through the through hole of the outer wheel body and is fixed on the support rod of the inner wheel body. The outer wheel body can slide along the control motor shaft to adjust the distance between the inner and outer wheel bodies, so as to adjust the width of the fiber rope after being tied and formed.

[0009] Furthermore, each support rod of the outer wheel body is provided with a row of through holes, and correspondingly each support rod of the inner wheel body is provided with a row of internal threaded holes, and one end of the rope winding rod connected to the inner wheel body is provided with external threads, and the rope winding rod is screwed and fixed in the internal threaded holes of the support rods of the inner wheel body. By adjusting the rope winding rods to pass through different through holes and fix them, the diameter of the space formed by the multiple rope winding rods can be adjusted, so as to adjust the inner diameter of the fiber rope after being tied and formed.

[0010] Furthermore, a guide wheel is provided on the upper part of the pay-off drum through a bracket, the bracket is mounted on the tray, and a circle of deep grooves is provided on the side of the guide wheel.

DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figure 1As shown, an embodiment of a fiber rope twistless binding device designed by the present invention is composed of three parts: a wire-releasing module 1, a detection module 2 and a binding and forming module 3.

[0024] The wire-paying module 1 includes a driving motor 11, a tray 12, a wire-paying reel 13 and a guide wheel 14. The driving motor 11 is arranged in a metal box, and its driving shaft is arranged upward. The tray 12 is arranged above the metal box, and a through hole is provided at the center of its bottom. A ball bearing 121 is fixed in the through hole, and the outer ring of the ball bearing 121 is fixedly connected to the through hole of the tray 12. The driving shaft of the driving motor 11 passes upward through the inner ring of the ball bearing 121 and is fixed. The pay-off drum 13 is arranged in the tray 12, and its bottom center is connected to the driving shaft of the driving motor 11, and is driven by the driving motor 11 to rotate horizontally. The pay-off drum 13 is cylindrical, and its top edge is turned outward to form a flange. The braided and rolled fiber rope is received in the pay-off drum 13 and rotates with the pay-off drum 13.

A guide wheel 14 is arranged above the pay-off drum 13, and the guide wheel 14 is mounted on the tray 12 through a guide wheel bracket 141. After the fiber rope comes out of the pay-off drum 13, it enters the downstream process through the guide wheel 14.

[0025] The detection module 2 is located downstream of the pay-off module 1, and includes a tension control wheel 22 and a rope meter 21. The fiber rope is passed around the wheel bodies of the tension control wheel 22 in sequence, and the tension of the rope during the tying process is adjusted by the tension control wheel 22. The rope meter 21 uses a wheel meter, and other forms of meter can also be used to replace it.

Rope guide wheels are respectively arranged on the upper and lower sides of the detector to ensure that the rope can pass through the detector reasonably and maintain the accuracy of the detection. Infrared detectors can also be used here. In the binding and forming module, the fiber rope first passes through the wire breakage detector 31, and then enters the rope reel 33 through the reciprocating wire arrangement device 32. The reciprocating wire arrangement device 32 evenly arranges the rope on the rope reel 33 through its reciprocating motion, and the rope reel 33 finally winds and binds the fiber rope. The signal of the rope meter 21 is connected to the control motor. When in use, the rope meter 21 is set to the required rope length value. When the length of the fiber rope passing through the rope meter 21 reaches the set value, the rope meter will automatically send a signal to the control motor, and the control motor will stop rotating.
