Description

Vertical wire storage rack for buffering cable tension

Technical Field

The invention relates to the technical field of winding equipment, in particular to a vertical wire storage rack for buffering cable tension.

Background

Communication cables (e.g., five types of cables) are typically stored on large diameter reels during factory production to improve efficiency, reduce transit times, and conserve warehouse space. Before leaving the factory, the cable needs to be coiled again, and is coiled on the wire coil with the small diameter from the wire coil with the large diameter, so that the cable can be conveniently plugged into a pull box or a paper packing box, loading and transportation are convenient, and workers can conveniently operate during site construction.

The existing coiling equipment generally comprises an uncoiler and a coiling machine, wherein a large wire coil is driven by a motor of the uncoiler to gradually release a cable, and a motor of the coiling machine is driven to drive a small-diameter wire coil to gradually coil under the guidance of a wire arranging device. The defects of the rolling mode are as follows: in the winding process, the wire diameter of the take-up reel is continuously increased, and the wire diameter of the pay-off reel is continuously decreased, so that the speed between the unreeling machine and the reeling machine is difficult to coordinate due to the dynamic change, and the tension of the cable is unstable during winding; if the paying-off speed is less than the taking-up speed, the situation that the cable is hard pulled easily occurs, so that the cable is wound too tightly; if the paying-off speed is greater than the taking-up speed, the cable is loosened, the cable is wound too loosely, and troubles are brought to boxing after the wire is taken up.

Disclosure of Invention

The invention aims to overcome the defects in the background art, and provides a vertical wire storage rack for buffering the tension of cables, which can automatically coordinate the coiling and uncoiling speeds, keep stable cable tension in the coiling process, avoid the phenomena of over-loose and over-tight coiling, and also has the technical characteristics of high automation degree and convenient operation.

The technical purpose of the invention is realized as follows:

a vertical wire storage frame for buffering the tension of a cable is characterized in that a first guide rail and a first sliding block are vertically arranged on the front side of a wire storage frame, a second guide rail and a second sliding block are vertically arranged on the back side of the wire storage frame, a group of upper wire guide wheels are arranged on the top of the front side of the wire storage frame through an upper fixed shaft, and a group of lower wire guide wheels are arranged on the front side of the first sliding block through a lower fixed shaft; a supporting plate is horizontally fixed at the upper part of the wire storage rack, a fixed pulley is arranged on the supporting plate, and a wheel shaft of the fixed pulley is connected with an angle sensor through a gear set; the first sliding block is connected with a rope, the rope is connected with the second sliding block after bypassing the fixed pulley, the second sliding block is provided with a group of balancing weights, and the angle sensor is electrically connected with the electrical control box.

Preferably, a wire feeding wheel is installed on the right side of the wire storage rack through a cantilever, and a wire discharging wheel is installed on the left side of the wire storage rack through a cantilever.

Compared with the prior art, the invention has the following advantages: according to the invention, the vertical wire storage frame can store a certain length of cables, and the lower wire wheel set can slide up and down through counterweight balance, so that buffering is realized between the coiling machine and the uncoiling machine, and the cables are prevented from being pulled hard or loosened excessively.

Detailed Description

The present invention will be further described with reference to the drawings attached to the specification, but the present invention is not limited to the following examples.

As shown in fig. 1 and 2, a vertical wire storage rack for buffering cable tension is characterized in that a first guide rail B7 (generally two guide rails) and a first sliding block B6 are vertically mounted on the front surface of a wire storage rack B1, a second guide rail B8 (generally two guide rails) and a second sliding block B14 are vertically mounted on the back surface of the wire storage rack B, a group of upper wire guide wheels B4 (each can freely rotate around an upper fixed shaft) are mounted on the top of the front surface through an upper fixed shaft, and a group of lower wire guide wheels B5 (each can freely rotate around a lower fixed shaft) are mounted on the front surface of a first sliding block B6 through a lower fixed shaft. A supporting plate B9 is horizontally fixed at the upper part of the wire storage rack B1, a fixed pulley B10 (which can be replaced by a chain wheel) is installed on the supporting plate B9, and the wheel shaft of the fixed pulley B10 is connected with an angle sensor B13 through a gear set B12. The first sliding block B6 is connected with a rope B16 (which can be replaced by a chain), the rope B16 is connected with the second sliding block B14 after passing around the fixed pulley B10, and the second sliding block B14 is provided with a group of counter weights B15.

The right side of the wire storage rack B1 is provided with a wire feeding wheel B2 through a cantilever, and the left side of the wire storage rack B1 is provided with a wire discharging wheel B3 through the cantilever.

The working principle of the invention is as follows:

firstly, a winding mode:

the cable winds to the foremost (or last) upper wire guiding wheel after clockwise winding around the wire feeding wheel, then winds between the upper wire guiding wheels and the lower wire winding wheel in a counterclockwise direction, and then comes out from the last (or foremost) upper wire guiding wheel to wind around the wire discharging wheel in a clockwise direction. [

Secondly, a control mode:

when the take-up motor is too fast, the tension of the cable can be too big this moment, the cable between upper wire wheel and the lower wire wheel can be pulled out, lead to the height rising of lower wire wheel (and the distance between the upper wire wheel diminishes, the process of release cable), the height of balancing weight leaves the equilibrium point and descends, the fixed pulley can produce the rotation, angle sensor sends for electrical control box after detecting the angle change, electrical control box control is received the line motor and is slowed down and receive the line, still unreel the motor and accelerate the unwrapping, the height of lower wire wheel can reduce gradually (and the distance between the upper wire wheel grow, the process of storing the cable), until the height of balancing weight reaches the equilibrium point, when the distance between the take-up pulley no longer changes, receive the line motor no longer slows down, unreel the motor no longer accelerates, keep steady operation.

Similarly, when the speed of the take-up motor is too low, the angle sensor detects the change of the angle and sends the change of the angle to the electrical control box, the take-up motor starts to accelerate, and the unreeling motor decelerates until the take-up motor operates stably again.

The above description is only a preferred embodiment of the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
