Hereinafter, the driving of the clutch unit 300 and the brake 400 will be described in more detail with reference to the accompanying drawings.

9 to 11 are diagrams for explaining the driving of the clutch portion and the brake. Hereinafter, the description of the above-described parts may be omitted.

The binding device 10A according to the present invention may include a driving switch SW1 for driving the clutch 300.

Here, the drive switch SW1 may be a switch for supplying power for driving to the clutch 300. Hereinafter, the driving switch S1 for driving the clutch 300 may be referred to as a first switch SW1.

Referring to FIG. 9, the first switch SW1 may be turned on in the first period D1.

Then, power is supplied to the clutch 300 in the first period D1 so that the clutch 300 may be activated (On). For example, a user (worker) may press the first switch SW1 to activate the clutch 300.

When the clutch 300 is activated, the clutch 300 may be in close contact with the belt wheel 200 by an electromagnet included in the clutch 300. The close contact between the clutch 300 and the belt wheel 200 is indicated in the region B in the figure.

In the first period D1, the first portion 410 and the second portion 420 of the brake 400 may be detached.

When the brake 400 is an electronic brake, the first part 410 and the second part 420 may be detached by cutting off the power supply to the brake 400. Desorption of the first portion 410 and the second portion 420 is indicated in area A in the figure.

In this first period D1, the rotational force of the motor 600 may be transmitted to the clutch shaft 100 through the belt wheel 200, and the clutch shaft 100 may rotate. In addition, the rotational force of the clutch shaft 100 is transmitted to the wheel stage 700 so that the wheel stage 700 may rotate around the first table 11 and the second table 12 to bind the package P. Since the binding method of the package (P) has been described in detail above, further description thereof will be omitted.

In the second period D2, the first switch SW1 may be turned off. In this case, the clutch 300 may be deactivated (Off).

Here, the electromagnet of the clutch 300 loses its magnetic force, which causes the clutch 300 to be detached from the belt wheel 200, and thus rotation of the wheel stage 700 may be interrupted.

In the second period D2, the first switch SW1 may be turned off.

Then, the power supply to the clutch 300 is cut off in the second period D2, so that the clutch 300 may be deactivated (Off).

When the clutch 300 is deactivated, the electromagnet included in the clutch 300 loses its magnetic force, and the clutch 300 may be detached from the belt wheel 200. Desorption of the clutch 300 and the belt wheel 200 is indicated in area D in the figure.

In the second period D2, the first portion 410 and the second portion 420 of the brake 400 may be in close contact with each other.

When the brake 400 is an electronic brake, by supplying electric power to the brake 400, the first part 410 and the second part 420 may be in close contact with each other by an electromagnetic force.

The close contact of the first portion 410 and the second portion 420 of the brake 400 is indicated in area C in the figure.

In this second period D2, the rotational force of the motor 600 is not transmitted to the clutch shaft 100, so that rotation of the clutch shaft 100 may be interrupted.

Through this process, the package P placed on the first table 11 and the second table 12 may be bound.

As described above, when the clutch 300 is electronically driven, the response speed may be increased to reduce the time required for binding the package P, thereby improving work efficiency. In addition, the structure of the binding device 10A can be simplified.

When the clutch is driven by using a foot switch, it may cause an injury to an operator due to repetitive motions.

On the other hand, when the clutch 300 is electronically driven as in the present invention, the operator can drive the clutch 300 with a relatively small force, thereby lowering the possibility of injury.

Hereinafter, the pressing unit will be described in detail.

12-15 is a figure for demonstrating a press part. Hereinafter, the description of the above-described parts may be omitted.

Referring to FIG. 12, the pressing plate 21 of the pressing unit 20 may be positioned above the first table 11 and may apply pressure toward the first table 11.

In this case, pressure may be applied to a portion corresponding to the first table 11 in the package P placed over the first table 11 and the second table 12.

It may be possible to drive the pressing unit 20 with a switch for driving the first switch SW1, that is, the clutch 300.

In other words, the clutch 300 and the pressing unit 20 may be driven together using the first switch SW1.

Referring to FIG. 13, the first switch SW1 may be turned on in the tenth period D10.

Even when the first switch SW1 is turned on in the tenth period D10, power is not supplied to the clutch 300, and the clutch 300 may maintain an inactive (Off) state.

On the other hand, the pressing unit 20 may be activated. In addition, the brake 400 is also activated (On) so that the first portion 410 and the second portion 420 of the brake 400 may be in close contact with each other.

In this case, the clutch shaft 100 may not rotate.

On the other hand, the pressing unit 20 is activated so that the pressing plate 21 may apply pressure toward the first table 11. Then, in the state as shown in (A) of FIG. 14, the pressure plate 21 may apply pressure to the package P placed on the first table 11 to reduce the volume of the package P.

Thereafter, in the eleventh period D11, power is supplied to the clutch 300 to activate the clutch. On the other hand, the brake 400 may be deactivated (Off) so that the first portion 410 and the second portion 420 of the brake 400 may be detached from each other.

Then, the pressure plate 21 may apply the pressure to the package P to bind the package P in a state in which the volume of the package P is reduced. Since the binding method of the package (P) has been described in detail above, further description may be omitted.

Thereafter, in the twelfth period D12, the first switch SW1 may be turned off. Then, both the clutch 300 and the pressing unit 20 may be deactivated (Off).

In this case, the pressing unit 20 may release the pressure as shown in FIG. 14A and may not rotate the clutch shaft 100.

Meanwhile, it may be possible to separately include a second switch SW2 for driving the pressing unit 20 separately from the first switch SW1 for driving the clutch 300.

Referring to FIG. 15, in the twentieth period D20, the first switch SW1 may be turned off and the second switch SW2 may be turned on.

Then, the clutch 300 may be deactivated according to the turn-off of the first switch SW1, and the pressing unit 20 may be activated according to the turn-on of the second switch SW2. In addition, the brake 400 is also activated (On) so that the first portion 410 and the second portion 420 of the brake 400 may be in close contact with each other.

In this case, the clutch shaft 100 may not rotate.

On the other hand, the pressing unit 20 is activated so that the pressing plate 21 may apply pressure toward the first table 11.

Thereafter, in the twenty-first period D21, the first switch SW1 may be turned on while the second switch SW2 is maintained in a turn-off state.

In this case, power may be supplied to the clutch 300 to activate the clutch. On the other hand, the brake 400 may be deactivated (Off) so that the first portion 410 and the second portion 420 of the brake 400 may be detached from each other.

Then, the pressure plate 21 may apply the pressure to the package P to bind the package P in a state in which the volume of the package P is reduced. Since the binding method of the package (P) has been described in detail above, further description may be omitted.

Thereafter, in the 22nd period D22, the first switch SW1 and the second switch SW2 may be turned off. Then, both the clutch 300 and the pressing unit 20 may be deactivated (Off).
