Description

Technical Field [0001] The present invention relates to an automatic apparatus for manufacturing a spiral cable protection tube,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for manufacturing a cable protective tube for protecting a cable around a cable such as various electric cables and hydraulic cables. In particular, in manufacturing a cable protective pipe having a cylindrical structure,

Unlike the conventional method, both the feeding process of the linear band type material and the initial winding process and the winding process are automatically performed, thereby maximizing the production effect and minimizing the defect occurrence rate and reducing the production time and production cost Technology.

Generally, many hydraulic cables and cable cables are used in various heavy equipments and many kinds of cables are used in various industrial equipments and buildings.

Most of these cables are shielded from the outside as they are inserted into a separate protection pipe while being bundled together.

In this case, the cable protection pipe used is a structure in which a linear band-shaped plastic material is wound in a spiral shape to have a pipe structure, and each cable is accommodated in such a manner as to penetrate the cable protection.

Unlike a simple tube-type protective pipe in which the entire circumference is clogged, the helical cable protection pipe is divided into the incisional form between the respective spiral sections. Therefore, in the process of storing the cable, some cables are pulled out or newly inserted And that the process is possible.

As mentioned above, the helical cable protection pipe is a cylindrical structure in which the first linear band type plastic material is wound during the manufacturing process,

In the past, when manufacturing such a spiral cable protection pipe, two workers, one end of a plastic material in a straight band form, were fixed to the end of another rotation shaft, and the two workers moved back and forth while manually rotating the rotation shaft manually It was produced in such a way that the linear band type material was wound on the rotating shaft in a spiral structure.

In other words, the helical cable shield which is currently being produced is manufactured through manual work, which not only takes a long time to produce, but also requires more than two workers at all times, so that the workforce can not be consumed quickly and quickly.

Also, since all the work is done by hand, the rotating speed of the rotating shaft is hard to be constant and the moving speed of back and forth is not constant. In order to continuously supply the materials, the supply speed is not constant, The possibility of occurrence of defects is also great,

These factors will inevitably lead to a deterioration in the overall production efficiency and increase the unit price of products.

The main body 1 is provided with a main drive motor 2 for rotating the main rotation shaft 4 to be described later.

The main drive motor 2 is installed on the rear side of the main body 1 in such a manner that the motor shaft penetrates the main body 1 forward.

A main rotation shaft 4 is connected to the main drive motor 2 thus installed.

The main rotation shaft 4 serves as a support and guide path for winding the linear band-like material 5, which is the material of the helical cable protection tube, in a spiral shape. The main rotation axis 4 is in the form of a straight circular rod having longitudinal- Is extended toward the front side in a state of being connected to the motor shaft of the main drive motor (2), and is inclined downward toward the front end.

Thus, the main rotation shaft 4 has a structure rotatable together with the motor shaft by the main drive motor 2.

A guide rail 3 for guiding a linear movement of the first winding guide portion 8 to be described later is formed in a rail groove shape along the entire longitudinal direction of the main rotation shaft 4 at both sides of the peripheral surface of the main rotation shaft 4 .

For reference, the front and rear lengths and the diameters of the main rotation shaft 4 are not limited to specific dimensions, and may be variously modified depending on the length, diameter, etc. of the spiral cable protection pipe to be manufactured.

The elevation induction cylinder 12, the elevation frame 13, the supply induction motor 14, and the supply induction roller 15 again.

The lifting and lowering induction cylinder 12 serves as a driving source for lifting up and down the lifting frame 13 and the feeding guide roller 15 to be described later. The lifting and lowering driving cylinder 12 is in the form of a hydraulic or pneumatic cylinder as a whole, And the cylinder rod located at the lower end portion is elevated and lowered in the up and down linear direction in the installed state.

The lifting and lowering frame 13 serves to support a supply induction motor 14 and a supply guide roller 15 to be described later and to raise and lower the supply guide motor 14 and the supply guide roller 15 And the upper end portion is integrally connected to the lower end of the cylinder rod of the elevation induction cylinder 12 in a state where the metal frames are interconnected as a whole and the elevation induction cylinder 12 is positioned below the elevation induction cylinder 12. [

The supply induction motor 14 serves as a driving source necessary for the rotation of the supply guide roller 15 to be described later. When a general electric motor is used and the motor shaft is fixed to the rear end of the lifting frame 13, .

The supply induction roller 15 constituting the material supply induction portion 16 together with the above-described lifting induction cylinder 12, the lifting frame 13 and the supply induction motor 14 is rotated by the driving force of the supply induction motor 14, , While pulling the linear band-shaped material (5) toward the feeding direction as it rotates while pressing a point located on the upper circumferential surface of the rear end of the main rotating shaft (4) As a result,

The center point is rotated in a state of being connected to the motor shaft of the supply induction motor 14 in a state of being a simple circular roller and positioned at a point above the upper circumferential surface of the rear end of the main rotating shaft 4, .

In this state, the linear band-like material 5 passes between the feeding guide roller 15 and the main rotating shaft 4, and at this time, the feeding guide roller 15 presses the linear band-like material 5 downward The linear band-like material 5 is pulled in a state of being sandwiched between the supply induction roller 15 and the main rotary shaft 4. As shown in Fig.

As the linear band-like material 5 fed onto the peripheral surface of the main rotation shaft 4 is fed in a state sandwiched between the supply induction roller 15 and the main rotation axis 4, the linear band- The linear band-like material 5 can be smoothly wound on the main rotary shaft 4 due to this, so that the linear band-like material 5 can be smoothly wound.

The main body 1 is further provided with a winding sustaining portion 17 in a state where the material supply leading portion 16 is provided.

The first winding inducing portion 17 is wound in a spiral shape by the first winding inducing portion 8 for the first time and then the first winding inducing portion 8 rotates together with the main rotating shaft 4 to linearly move The straight band-shaped material 8 (without the first winding inducing portion 8) is wound from the time when the first winding induction portion 8 is completely disengaged from the main rotation shaft 4 through the front end portion of the main rotation shaft 4 5) to keep the spiral of the spiral continuously,

A plurality of pressure sustaining wires 21 are simultaneously wound around the respective tension sustaining rollers in a state where three tension sustaining rollers are arranged, Are simultaneously rotated in an endless track shape.

The winding sustaining inducing portion 17 is disposed on one side of the main rotating shaft 4 so that each of the pressing sustaining wires 21 are arranged obliquely to the side of the main rotating shaft 4 and horizontally arranged horizontally with each other, .

In this state, each pressure sustaining wire 21 is located at a position slightly forward of the main induction roller 15 in the main rotary shaft 4 and is fed by the main supply induction 15 of the linear band- And is rotated in a state in which the contact point is pressed in order from the point where it is initially wound on the rear main shaft 4 toward the front side.

As the pressure sustaining wire 21 presses the vicinity of the winding starting point of the linear band-like material 5 in the oblique direction, the vicinity of the supply band 15 fed from the linear band-like material 5 is naturally supplied to the main The linear band-shaped material 5 is guided to be wound in a spiral shape while the first winding induction portion 8 is initially rotated to move forward, and then the main rotation axis 4 , The linear band-like material 5 continuously fed thereafter is continuously guided by the winding sustaining portion 17 so that normal spiral winding can be continued.

In addition to the structure of the pressure sustaining wire 21 as shown in Fig. 7, the winding sustaining inducing portion 17 is provided with a plurality of pressure rollers 18 arranged on both sides of the main rotating shaft 4 with a front- ) Of the linear band-like material 5 supplied onto the surface of the linear band-like material 5.

The winding sustaining portion 17 of this type is provided with the linear band-like material 5 and the linear band-like material 5 on the side of the main rotary shaft 4, with each pressure roller 18 being positioned on both sides of the main rotary shaft 4 Are arranged horizontally in front of and behind each other in the same oblique direction and simultaneously rotate in the opposite direction to the main rotation axis 4 in this state.
