Figure 1 is a schematic perspective view for explaining a GB flexible cutter, Figure 2 is a schematic cross-sectional view for explaining the polishing part.

1 and 2, the GB flexible cutter 100 includes a frame 110 supporting the support plate 20, a grinding unit 120 capable of grinding the supplied glazing bead 10, and the glazing bead. It may include a fixing part 130 capable of fixing (10).

The frame 110 may be formed to extend vertically upward from the ground to have a four-axis shape supporting the support plate 20 .

The support plate 20 is supported by the frame 110 and is formed in a flat plate shape to support the polishing part 120 and the fixing part 130 .

The polishing part 120 includes a movable plate 121 disposed on the support plate, and a guide rail 122 formed on the support plate 20 so that the movable plate 121 can advance and retreat from the top of the support plate 20 . ), a movable member 123 formed under the movable plate 121 to allow the movable plate 121 to move along the guide rail 122 , a rotation disposed on the movable plate 121 . A possible drive shaft 124 , a polishing unit 126 including polishing blades 125 formed at regular intervals on the drive shaft 124 , can rotate the drive shaft 124 , and disposed on the support plate 20 . It may include a driving unit capable of advancing and retreating the movable plate 121 in the direction of the glazing bead 10 .

The abrasive unit 120 may be disposed on the first driving source 127 and the support plate 20 enabling rotation of the abrasive blade 125 . In addition, a second driving source 128 capable of moving the movable plate 121 in the direction of the glazing bead 10 may be included.

The first driving source 127 may be fixed to the upper surface of the movable plate 121 , and may be directly connected to the driving shaft 124 to provide a rotational force for rotating the driving shaft 124 . The first driving source 127 may include an AC motor, a DC motor, a single-phase motor, and a three-phase motor.

The second driving source 128 may be fixed on the support plate 20 . In addition, the second driving source 128 is an LM motor that can provide a linear driving force for moving the rotating driving shaft 124 forward or backward in the direction of the glazing bead 10, a solenoid and a hydraulic cylinder. can

The movable plate 121 is disposed on the support plate 20 to advance and retreat along the upper surface of the support plate 20 , and the polishing unit 125 provided on the movable plate 121 is applied to the blade. You can advance and retreat with the gong bead (10).

In addition, the guide member 123 may be installed at a lower portion of the movable plate 121 to move forward and backward along the guide rail 122 installed on the support plate 20 . The guide rail 122 and the guide member 123 may include an LM guide, a roller guide, or a ball guide.

A plurality of the abrasive blades 125 may be formed to protrude at regular intervals of about 3 to 4 cm in the longitudinal direction of the driving shaft 124 with respect to the driving shaft 124 . The abrasive blade 124 may be in the form of a disk having a diameter of 11 to 15 cm in the longitudinal direction. This may be for grinding blazing beads of various specifications rather than only one type of blazing beads. For example, the porcelain glazing bead can be ground with a deeper and narrower gap to allow the glazing bead to bend more easily. Conversely, in a situation where a glazing bead that does not bend easily is required, the effect of grinding according to the situation occurs by replacing the diameter of the blade and the number of blades.

In addition, the abrasive blade 125 may be made of a stainless material having less rust and corrosion than general iron.

3 is a schematic cross-sectional view for explaining a polishing part and a fixing part.

Referring to FIG. 3 , the fixing part 130 may be disposed on the front support plate 20 of the polishing part 120 . The fixing part 130 is a support member 131 extending vertically upward from the support plate 20 to support the supplied glazing bead 10 , and is disposed on the outside of the support member 131 , and the It may be composed of a fixing frame 132 extending vertically upward from the support plate 20 , and a fixing unit 133 connected to the fixing frame 132 to fix the glazing bead 10 .

The fixing unit 133 includes a fixing member 134 for fixing in direct contact with the glazing bead 10 and a third driving source connected to the fixing member 134 to elevate the fixing member 134 . (135).

The bottom surface of the fixing member 134, that is, the surface in direct contact with the glazing bead 10, is made of a material capable of absorbing shock, such as a silicon pad, to prevent phenomena such as damage when the glazing bead 10 is fixed. may have a preventive effect.

The third driving source 135 may be configured as an LM motor, a solenoid, or a hydraulic/pneumatic cylinder capable of providing a linear driving force like the second driving source 128 .

In addition, the fixing unit 130 of the GB flexible cutter 100 receives a signal from the detection unit 200 and the safety unit 200 for the safety of the operator to operate the first, second and third driving sources. It may further include a control unit 140 that can control the.

The control unit 140 is connected to the first drive source 127 , the second drive source 128 , and the third drive source 135 , and may receive data transmitted by the sensor of the safety unit 200 .

The sensing unit 200 may be disposed on the fixing members 133 to face each other. The sensing unit 200 includes a pair of sensors including a light emitting unit 210 for irradiating light and a light receiving unit 220 for receiving light. ) of the polishing unit 125 of the same height, respectively, may be disposed on a horizontal line orthogonal to the direction approaching the glazing bead (10). When the light receiving unit 220 receives light and continuously transmits a signal to the control unit 140, as described above, the GB flexible cutter 100 operates without abnormality, but the height of each of the fixing members is different. When the light receiving unit 220 does not receive the light irradiated by the light emitting unit 210 for more than a preset period of time, the control unit 140 determines that the signal cannot be received by the control unit 140 and thus a malfunction or a finger is pinched. ) may control the third driving source 135 to maximally raise the fixing members 134 and stop the first driving source 127 and the second driving source 128 . For this reason, when an accident such as being caught in the fixing member 134 occurs, by immediately stopping the operation of the GB flexible cutter 100, the occurrence of a safety accident can be prevented in advance, thereby minimizing human damage. In addition, the operator can check the state of the GB flexible cutter 100 from the outside through the terminal connected to the outside through wired/wireless communication with the controller 140. For example, using a sensor, the By further attaching a sensor capable of counting the number or the rotational speed of the abrasive blades 125 and the number of advances and retreats of the movable plate 121, the state of the GB flexible cutter 100, the amount of work or the work efficiency Since the control unit 140 collects information and transmits the collected data to an external terminal, it is possible to check the information from the outside through the terminal in real time.

Also, the controller 140 may control the speed or the number of rotations of the first driving source 127 , the second driving source 128 , and the third driving source 135 . For example, the load applied to the polishing unit 126 by reducing the instantaneous speed at which the polishing unit 126 touches the blazing bead 10 rather than the moving speed of the second driving source 128 retreating in the front-rear direction. In addition, the occurrence of defective products can be reduced. In addition, the control unit 140 controls the retraction speed of the second driving source 128 after the polishing operation of the glazing bead 10 is finished faster than the speed of approaching the glazing bead, thereby reducing power wastage. .

Referring to FIG. 4 , the operation sequence of the GB flexible cutter 100 can be seen.

First, the glazing bead 10 is supplied on the support member 131 , and the fixing unit descends and a fixing step of fixing the glazing bead 10 is performed. After the fixing step, the light emitting unit 210 and the light receiving unit 220 check whether both fixing members 134 are located at the same height, the inspection step is continuously during the process of grinding the glazing bead (10) An inspection step is performed. By continuously performing the inspection step, it is possible to prevent human accidents and minimize the malfunction of the machine to improve the lifespan of the GB flexible cutter 100 and its stability. When the fixing step is finished, the next step, the first driving unit 127 rotates the driving shaft 124 , thereby proceeding to a rotating step of rotating the polishing unit 126 . After that, the second driving source 128 may operate to push the movable plate 121 so that the polishing unit 126 polishes the glazing bead 10 . After the polishing operation is completed, the above-described steps may be performed in the reverse order.

On the other hand, it is natural that vibration occurs and the material is damaged due to repeated operations. You just know how to slow it down. Each of the abrasive blades 125 may be frequently damaged due to fatigue accumulation, etc., such as cracks or damage due to vibration due to repetitive work.

Therefore, as the abrasive blades 125 are replaced with vibration-reducing abrasive blades, a phenomenon such as fatigue failure is prevented, and thus, the replacement cost of the abrasive blade 125 is reduced. These advantages necessitate a vibration damping abrasive blade. Therefore, what will be described later shows the configuration of a vibration-reduced abrasive blade that reduces vibrations on the abrasive blade. When the vibration-reduced abrasive blade is applied to the GB flexible cutter 100, the vibration applied to the blade is reduced, so that the abrasive blade 125 is applied. As a result, the lifespan of the GB flexible cutter 100 is also increased by reducing the vibration of the .
