In the present specification, the same or similar reference numerals are assigned to the same or similar configurations in different embodiments, and the description thereof is replaced with the first description.

Hereinafter, referring to FIGS. 1 and 2, a bar cutting device as a temporary example of the present invention will be described.

1 is a schematic block diagram of a bar cutting device as an embodiment of the present invention, Figure 2 is a schematic block diagram of a bar cutting device as an embodiment of the present invention.

1 and 2, the bar cutting device as a temporary embodiment of the present invention, the conveying conveyor 10, the sensor 20, the press 30, the touch screen 40, the control unit 50 and the residue processing unit (60).

The conveying conveyor 10 is an apparatus configured to convey the bar (rebar etc.) which is a conveying object, and the conveying steel 10 is conveyed to the press 30 mentioned later by the conveying conveyor 10. As shown in FIG.

The sensor 20 is configured to detect the transferred bar and to measure the length of the bar. A laser light sensor may be used as an example of the detection sensor 20, and in this case, detection performance may be greatly improved. The configuration of the sensor 20 will be described in more detail with reference to FIG. 3.

The press 30 is an element configured to cut the steel bar conveyed through the conveying conveyor 10 to the length (preset length) of the final product. Operation may be started by the sensor 20, and the specific operation may be controlled by the controller 50 to be described later.

The touch screen 40 is a component for not only displaying the processing result of the controller 50 to be described later but also inputting a command for the bar cutting device. For example, a command for setting the length of the final product, a command for setting the working time, and the like may be input through the touch screen 40.

The touch screen 40 is a device in which a display unit and a sensor for detecting a touch operation (hereinafter, referred to as a “touch sensor”) have a mutual layer structure and may be used as an input device in addition to an output device. The touch sensor may have, for example, a form of a touch film, a touch sheet, a touch pad, or the like.

The touch sensor may be configured to convert a change in pressure applied to a specific portion of the display unit or capacitance generated at a specific portion of the display unit into an electrical input signal. The touch sensor may be configured to detect not only the position and area of the touch but also the pressure at the touch.

The control unit 50 measures the length of the bar through the length between the detection sensor 20 and the press 30, and the length of the bar and the length of the final product of the preset end of the press 30 It calculates the number of cutting, and serves to control the press 30 to cut the bar by the calculated number of cutting. In other words, when the end of the bar is endured in the sensor 20, the length between the sensor 20 and the press 30 becomes the length of the remaining bar, and divide the length of the remaining bar by the length of the predetermined final product If so, the number of cuts is determined. Then, the press 30 is operated only for the number of times of cutting. On the other hand, the remaining residue is transferred to the residue processing unit 60 to be described later.

Residual storage unit 60 is a component for processing the residual of the remaining steel bar after cutting the steel bar to produce the final product. The controller 50 may control a rejector (not shown) to cut the steel bar by the cutting frequency, and then transfer the residue of the steel bar to the residue processing unit 60.

Hereinafter, the operation of the bar cutting device which is an embodiment of the present invention to be described in more detail with reference to FIG. On the other hand, it will be described below with reference to Figure 3 the sensor 20 used in the bar cutting device which is an embodiment of the present invention.

As shown in FIG. 2, the sensing sensor 20 may be installed on the conveying conveyor 10 before the predetermined distance from the press 30. Referring to the operation of the sensor 20, if the light emitted from the laser light emitting portion 21 is not irradiated to the light receiving portion 22, it is determined that there is a bar, and the light emitted from the laser light emitting portion 21 When it is irradiated to the light receiving unit 22, it is determined that the final end of the bar has passed the portion where the sensor 20 is installed.

Accordingly, the remaining length of the bar will be the length between the sensor 20 and the press 30, and dividing it by the length of the final product, the number of cutting of the remaining press 30 is determined.

As shown in FIG. 3, when the laser light emitting unit 21 and the light receiving unit 22 are fixed by the fixing member 23, the bar is collided with the detecting sensor 20 when entering the steel bar. The failure can be prevented to some extent. That is, the fixing member functions as a shock absorbing member.

Hereinafter, a bar cutting method according to an embodiment of the present invention will be described in detail with reference to FIG.
