1. A scattered powder cleaning device comprising:
a case formed at one side thereof with a gate for entrance and exit of glass and having an internal space defined therein;
a shut-off member opening and closing the gate;a powder injector provided in the case and injecting an amount of powder into the internal space;a cleaning unit forcibly scattering the powder in the internal space to discharge the powder from the case by forcibly introducing external air into the case, when the glass is shifted from the internal space; and a controller, wherein the cleaning unit comprises
a suction module configured to suction powder present in the internal space of the case;a vacuum pump configured to impart vacuum suctioning force to the suction module to discharge the powder outside; andthe case provided with a blower and said blower configured to forcibly introduce the external air into the internal space of the case,wherein the suction module comprises a lateral suction module and a lower suction module configured to provide suction from a lower side of the glass,
wherein the lateral suction module comprises a plurality of the first vacuum holes formed in sidewalls of the internal space of the case and a plurality of first discharging pipes respectively connected to the first vacuum holes and to the vacuum pump and,wherein the lower suction module comprises a plurality of second vacuum holes formed in a lower surface of the internal space of the case and a plurality of second discharging pipes respectively connected to the second vacuum holes and connected to the vacuum pump,wherein the vacuum pump comprises a first vacuum pump configured to impart vacuum suctioning force to the lateral suction module, and a second vacuum pump configured to impart vacuum suctioning force to the lower suction module,wherein the controller is configured to generate a control signal to operate the first vacuum pump and the second vacuum pump,wherein the case comprises a sensor configured to sense presence of the glass and transmit a sensing signal to the controller, and a rotation motor configured to operate the shut-off unit to open and close the gate in response to a control signal of the controllerwherein the controller is configured to operate the first vacuum pump to discharge the powder outside through the lateral suction modules when the glass is placed in the internal space of the case and the gate is closed, andwherein the controller is configured to control the blower to generate forcible circulation the external air within the internal space of the case and operate the first vacuum pump and the second vacuum pump to discharge the powder outside through the lateral suction modules and the lower suction module when the glass is removed from the case and the gate is closed, wherein in the case,
the first vacuum holes and the second vacuum holes are formed in a body having a plate shape,the body is arranged to form a wall of the case and the body is rotatably supported by a rotational shaft disposed in the case such that the body can be rotated up and down or left and right in the wall of the case,an edge of the body is connected to an edge of the case by a pleated cover, and the rotational shaft is rotated in response to a control signal from the controller. |
