Hereinafter, a coil binding apparatus and a control method thereof according to various embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view of a coil binding apparatus 1000 according to an embodiment of the present invention, and FIG. 2 is a side view of FIG.

Referring to FIGS. 1 and 2, a coil binding apparatus 1000 according to the present invention includes a frame 100, a hook member 200 provided on the frame 100 and wound with a wire coil C, A pair of compactor units 300 and 400 which are movable along the wire 100 and can control the pressure when the wire coil C is pressed, A cylinder 130 connected in parallel with a first pump 700 (see FIG. 7) and a second pump 710 (see FIG. 7) which are pressure-adjustable and have different capacities and pressures, A welding unit 500 for welding a band (not shown), which is provided in any one of the first and second coil units 300 and 400 and binds binding wires (not shown) for binding the wire coil C, And a lift (600) movably provided. Further, the coil binding apparatus 1000 may further include a controller (not shown) for controlling the driving of the compression units 300 and 400, the cylinder 130, the welding unit 500 and the lift 600 .

The frame 100 forms the base of the coil binding apparatus 1000 according to the present invention and is made of an I-beam or the like so as to provide adequate strength to support the load of the wire- have. Various components described later may be provided on the upper portion of the frame 100.

The hook member 200 is disposed on the upper portion of the frame 100. As shown in the figure, the hook member 200 is formed in a substantially 'C' shape or a 'C' shape so that the wire member coil C is wound. The wire coil C is pressed and bound by a compression unit 300 or 400, which will be described later, in a state where the wire member coil C is hooked on the hook member 200 as shown in the figure. This will be described later.

The pair of compression units 300 and 400 may include a first compression unit 300 and a second compression unit 400 and may be movable along the frame 100. For example, a guide rail 110 is provided on one side of the frame 100, and the first compression unit 300 and the second compression unit 400 are configured to move along the guide rail 110 .

At this time, the cylinders 130A and 130B may be provided as a power source for moving the pair of the compression units 300 and 400. For example, the first support bar 120A may be provided on one side of the frame 100, and the first cylinder 130A may be fixed to the first support bar 120A. In this case, the first driving arm 132A of the first cylinder 130A may be connected to the first compression unit 300. [

Similarly, the second support bar 120B may be provided on the other side of the frame 100, and the second cylinder 130B may be fixed to the second support bar 120B. In this case, the second driving arm 132B of the second cylinder 130B may be connected to the second compression unit 400. [

Therefore, the first and second driving arms 132A and 132B are extended or contracted by the driving of the first cylinder 130A and the second cylinder 130B, The first pressing unit 300 and the second pressing unit 400 move along the guide rail 110.

In this case, the coil binding apparatus 1000 according to the present invention is configured such that the pressure can be adjusted when the wire coil C is pressed by the pair of the compression units 300 and 400. [ Accordingly, the pair of cylinders 130A and 130B, that is, the first cylinder 130A and the second cylinder 130A, which provide pressure to the compression units 300 and 400 when compressed by the compression units 300 and 400, The cylinder 130B is configured to be pressure-adjustable. The first cylinder 130A and the second cylinder 130B are configured to be capable of controlling the pressures of the first cylinder 130A and the second cylinder 130B through the first and second driving arms 132A and 132B, The pair of compression units 300 and 400 connected to the second cylinder 130B can also be pressure-controlled.

In this case, when the wire rod coil C is pressed, the second compression unit 400 moves toward the first compression unit 300 by driving the second cylinder 130B to rotate the wire rod coil C ). Similarly, when the first cylinder 130A is driven, the first compression unit 300 moves toward the second compression unit 400 to press the wire coil C. As shown in FIG.

When the pair of the compression units 300 and 400 press the wire coil, the pair of the compression units 300 and 400 are preferably compressed under the same pressure. When the pressures of the pair of compression units 300 and 400 located on both sides of the wire coil C are different from each other, the pushing force of the wire coil C in one direction becomes strong, And it is possible to cause damage to the wire coil C as well.

The first compression unit 300 may include a first support plate 310 movably disposed along the upper portion of the frame 100 and a second support plate 310 provided on the first support plate 310, And a first pressing part 320 contacting the one end of the first pressing part 320.

The first support plate 310 is configured to be movable along the guide rail 110 of the frame 100. The first drive arm 132A of the first cylinder 130A is supported by the first support plate 110, Gt; 310 < / RTI > Therefore, when the first cylinder 130A is driven, the first support plate 310 is moved along the guide rail 110. As shown in FIG.

The first presser 320 is attached to the first support plate 310 and is brought into contact with one end of the wire coil C when the wire coil C is pressed.

At this time, the wire rod coil C may be damaged by the first pressing portion 320. Accordingly, the first pressing part 320 may be made of a material that can protect the wire rod coil C, and may be made of, for example, a spheroidal graphite cast iron (FCD).

The second compression unit 400 includes a second support plate 410 movably disposed along the upper portion of the frame 100 similar to the first compression unit 300, And a second crimping portion 420 provided on the wire coil C and contacting one end of the wire coil C. [ Since the components of the second compression unit 400 are similar to those of the first compression unit 300, repetitive description thereof will be omitted.

Meanwhile, the welding unit 500 is provided in any one of the pair of compression units 300 and 400 to weld a band for binding a binding wire (not shown) for binding the wire rod coil C.

The lift 600 is vertically movable to adjust the height of the wire coil C when the wire coil C is pressed by the pair of compression units 300 and 400 .

That is, when the wire rod coil C is pressed by the pair of the compression units 300 and 400 as described above, the height of the wire rod coil C is higher than the height of the first compression unit 300 and the second If the welding unit 500 does not meet the pressing unit 400 exactly, the welding operation can not be accurately performed. Therefore, by adjusting the height of the wire rod coil C by moving the lift 600 up and down to adjust the height of the wire rod coil C, the wire rod coil C is moved in the first and second compression units 300, So that the welding operation can be performed more precisely by the welding unit 500.

3 is a side view of the welding unit 500 in FIG.

Referring to FIGS. 1 and 3, the welding unit 500 may be provided in the first compression unit 300, for example. The welding unit 500 is provided in the first compression unit 300 and welds the band for binding the binding wire described above to bind the wire coil.

Specifically, the welding unit 500 includes a plurality of radially extending welding heads 500A, 500B, 500C, and 500D. For example, the coil binding apparatus 1000 according to the present embodiment includes the welding heads 500A, 500B, 500C and 500D as shown in the figure when the welding heads 500A, 500B, 500C and 500D are provided. ) May be provided.

When a plurality of the welding heads 500A, 500B, 500C, and 500D are welded, that is, four welding heads are welded, the time can be shortened and the production amount can be increased.

Also, in the coil binding apparatus 1000 according to the present invention, the welding heads 500A, 500B, 500C and 500D may be provided so as to be able to adjust back tension. Thereby, it is possible to freely convert from high speed and low torque to low speed and high torque. For this purpose, an air motor can be mounted on the transmission.

In this case, the tensioning force of the welding heads 500A, 500B, 500C and 500D indicates a maximum value of 13.7 N (1,400 kg) in the state of the air motor of about 0.55 MPa (5.5 kg / cm2G). Further, the tensile strength shows a value of approximately 54 kg / mm 2.

Hereinafter, a control method of the coil binding apparatus 1000 having the above-described configuration will be described.

4 is a flowchart showing a control method of the coil binding apparatus 1000 according to the present invention.

4, a control method according to the present invention includes a pair of compression units 300 and 400 movably provided to compress a wire coil C, a binding wire (not shown) for binding the wire coil C, And a lift (600) provided so as to be movable up and down to support the wire rod coil (C), the control method of the coil binding apparatus (1000) A step S430 of setting the maximum value of the pressing pressure by the pressing members 300 and 400 and a step S430 of advancing the pressing units 300 and 400 to press the wire coil C, A step S470 of welding the band by the welding unit 500 and a step S490 of reversing the compression unit 300 and 400 by the welding unit 500, .

Initially, the first compression unit 300 and the second compression unit 400 are separated from each other to be in a non-squeezed state, wherein the wire coil C is hooked to the hook member 200.

In this state, the worker sets the maximum value of the squeezing pressure when the wire coil C is squeezed from the coil binding apparatus 1000 (S410). The coil binding apparatus 1000 may include an input unit (not shown) for inputting the maximum value, and the input maximum value may be a control unit (not shown) for controlling the operation of the coil binding apparatus 1000 ) Or the like.

The maximum value may be appropriately adjusted according to the driving environment of the location where the coil binding apparatus 1000 is installed, the type of the wire coil C, and the like.

Subsequently, the crimping units 300 and 400 are advanced to press the wire coil C (S430). 5 is a schematic view showing a process of pressing the wire rod coil C by the compression units 300 and 400.

Referring to FIG. 5, the step of pressing the wire rod coil C may be performed according to the advancing distance of the compression unit 300 or 400. For example, as shown in the figure, when the compression units 300 and 400 are advanced toward each other to press the wire coil C, a section in which the compression units 300 and 400 are advanced is referred to as 3 Can be divided into four sections. In this case, the speed at which the compression units 300 and 400 move may be set to be different from each other in each section.

That is, in the first section A, the compression units 300 and 400 advance at a first speed, and in the second section B, the compression units 300 and 400 advance at a second speed, In the third section (section C), the compression units 300 and 400 advance at the third speed.

In this case, the first speed may be set relatively fastest among the first speed, the second speed and the third speed, and the third speed may be set relatively slow.

That is, in the case of the section A in which the compression units 300 and 400 are initially started, the compression unit 300 or 400 moves at a relatively high speed at the first speed. When the compression unit 300 or 400 reaches the section B through the section A, Is moved at the second speed corresponding to the relatively intermediate speed. Then, when the compression units 300 and 400 reach the section C which is the last section in which the wire coil C is squeezed, the compression units 300 and 400 move at the third slowest speed relatively.

In order to prevent the hook member 200 from interfering with the second compression unit 400 when the second compression unit 400 moves toward the first compression unit 300, The interference preventing groove 412 may be provided on the second support plate 410 of the compression unit 400. [

That is, when the second compression unit 400 moves toward the first compression unit 300, the hook member 200 penetrates the interference prevention groove 412 of the second compression unit 400, Can be prevented.

On the other hand, when the wire rod coil C is compressed by the compression unit 300 or 400 as described above, the maximum compression pressure is determined according to a preset maximum value. Therefore, when the crimping unit 300 or 400 actually moves and presses the wire rod coil C, its pressing pressure should not exceed the preset maximum value.

However, the compression pressure applied to the wire rod coil C by the compression units 300 and 400 may exceed the maximum value due to a malfunction of the compression units 300 and 400. Accordingly, in the control method according to the present invention, in the step of pressing the wire coil C, when the compression pressure by the compression units 300 and 400 exceeds the set maximum value, the compression units 300 and 400 are stopped .

Specifically, stopping the compression unit 300, 400 may stop the compression unit 300, 400 when the compression unit 300, 400 reaches a predetermined limit position. That is, the limit positions of the compression units 300 and 400 can be set in advance when the compression units 300 and 400 are advanced to press the wire coil C. [ When the pressing unit (300, 400) moves beyond the limit position, the limit position is determined so that the pressing pressure acting on the wire coil (C) exceeds a preset maximum value. Therefore, when the compression units 300 and 400 reach the limit position, the compression units 300 and 400 are stopped so as not to advance further.

At this time, the coil binding apparatus 1000 may further include a position sensor (not shown) for checking the positions of the pressing units 300 and 400. The control unit may determine the position of the compression unit 300 or 400 by the position sensor to determine whether the compression unit 300 or 400 has reached the limit position.

The step of stopping the compression unit may include pressing the compression unit 300 or 400 through a relief valve (not shown) of the cylinder 130 driving the compression unit 300 or 400, Can be stopped.

That is, when a relief valve is formed in the cylinder 130 for driving the compression unit 300 400 and the compression unit 300 or 400 is to be stopped, the pressure is discharged through the relief valve, 130 can be stopped and the pressing units 300, 400 can be stopped.

After the wire coil C is squeezed, the lift 600 is lifted to support the wire coil C (S450), and the band is welded by the welding unit 500 (S470).

FIG. 6 is a perspective view showing a coil binding apparatus 1000 in a state in which a wire coil is pressed in the state of FIG. 1, and FIG. 7 is a side view of FIG.

6 and 7, in the case of forming the squeezed state as described above, the lift 600 located at the lower part rises to adjust the height of the wire rod coil C so that the wire rod coil C rotates about the first The pressing unit 300 and the second pressing unit 400 can be accurately brought into contact with each other, and furthermore, the welding operation can be performed more precisely by the welding unit 500.

Next, the welding band 500A, 500B, 500C, 500D of the welding unit 500 welds the band that binds the binding wire described above.

After completing the welding, the compression units 300 and 400 are retracted (S490).

Referring again to FIG. 5, after completing the welding operation, the compression unit 300, 400 is reversed at a fourth speed in the D section. At this time, the fourth speed at which the compression units 300 and 400 are retracted may be set to be relatively faster than the second speed and the third speed. Here, the fourth speed may be set equal to the first speed.

8 is a configuration diagram of a pump for driving the cylinder.

8, the coil binding apparatus 10000 may include a plurality of pumps for driving the cylinder 130. For example, as shown in the drawing, the first pump 700 and the second pump The first pump 700 and the second pump 710 may have different capacities and pressures from each other. For example, the first pump 700 may include a first pump 700, The capacity of the first pump 700 is 210 to 215 LPM and the pressure of the first pump 700 is 6.5 to 7.0 MPa in the present embodiment. And the second pump 710 may have a capacity of 70 to 75 LPM and a pressure of 20 to 25 MPa.

In this case, the control unit of the coil binding apparatus 1000 selects any one of the first pump 700 and the second pump 710 according to the moving speed of the compression unit 300 or 400, Can be driven. That is, a plurality of pumps are provided in comparison with the case where the cylinder is driven irrespective of the speed of the compression unit by providing one pump, and when the cylinder is driven by selecting an appropriate pump according to the speed of the compression unit, .

The control unit drives the cylinder 130 by the first pump 700 when the compression unit 300 or 400 moves at a relatively high speed and controls the compression unit 300, The second pump 710 drives the cylinder 130. In this case,

As a result, the control unit drives the cylinder 130 by the first pump 700 when the compression unit 300 or 400 moves at the first speed, the second speed and the fourth speed, When the compression units 300 and 400 move at the third speed, the cylinder 130 is driven by the second pump 710.

Meanwhile, reference numeral 720, which is not described in FIG. 8, shows a motor for operating the first pump 700 and the second pump 710.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. You can do it. It is therefore to be understood that the modified embodiments are included in the technical scope of the present invention if they basically include elements of the claims of the present invention.
