Description

판형 자재상의 홀칩과 이물을 제거하는 세정장치 {Cleaning apparatus of removing hole chip, dust and particle of sheet material}Cleaning device of removing hole chip, dust and particle of sheet material}

본 발명은 판형자재와 시트류의 건식세정장치에 관한 것으로, 판형부재와 시트류를 톰슨재단기나 Die cutting machine의 목형 또는 금형프레스 가공 작업중 발생하는 각종형태의 홀칩(hole chip)과 먼지, 분진등을 판형자재와 시트류의 손상없이 제거 분리하는데 있어 비접촉식 방법으로 공기를 효과적으로 판형자재와 시트류에 분사하여 제거 분리하는 세정창치에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dry cleaning apparatus for sheet materials and sheets, and includes various types of hole chips, dust, dust, etc., generated during a wood or mold press operation of a thomson cutter or die cutting machine. The present invention relates to a cleaning window for efficiently removing and separating air by spraying air to the plate-like material and sheets in a non-contact manner to remove and separate the plate-shaped material and sheets without damage.

LCD TV나 모니터의 BLU(back light unit) 제조과정에 있어 LED의 빛을 효과적으로 반사하여 LCD 액정에 빛을 투사해 주는 반사원단(200, 210)의 경우, 도면2와 같이 다수의 원형 LED광원을 균일하게 배치하기 위해 목금형 프레스의 작업을 통해 다수의 원형타공이 필요하다. In the case of the BLU (back light unit) manufacturing process of the LCD TV or monitor, the reflective fabrics 200 and 210 that reflect the light of the LED and project the light to the LCD liquid crystal, as shown in Figure 2, a plurality of circular LED light sources In order to uniformly arrange, a number of circular holes are required through the operation of the die press.

기존 프레스 작업시 홀칩의 제거는 도3에서 도시한바와 같이 소량발생의 경우 목형틀(250) 후면에 홀칩집(260)을 두어 일정시간 작업후 모아진 홀칩(220)을 제거해 왔다. 그러나, 다량의 홀칩(220)이 발생하게 되면 홀칩을 모아두는 공간이 포화가 되어 더 이상 홀칩을 목형틀에서 수거하지 못하고 프레스 타발후 가공된 시트(210)와 함께 홀칩이 배출되게 된다. 이 홀칩은 BLU 조립과정중 불량을 야기시키는 이물로써 기존 건식 크리닝롤러 세정기(230,240)를 통과 시켜 제거하고 작업자의 육안검사와 수작업으로 홀칩을 제거해 왔다. 그러나, 시트형태 자재의 특성상 수작업이 용이하지 않고 수작업으로 원단을 흔들어 홀칩을 제거하는 행위는 작업시간이 증가되고 불량율을 높이게 되는 원인이 된다.
As shown in FIG. 3, the removal of the hole chips during the conventional press work has been carried out by removing the hole chips 220 collected after a certain period of time by placing the hole chip collection 260 on the back of the wooden frame 250 in the case of a small amount. However, when a large amount of the hole chip 220 is generated, the space for collecting the hole chip becomes saturated, and thus, the hole chip is discharged together with the processed sheet 210 after pressing the hole chip. This hole chip is a foreign material causing defects during the BLU assembly process, and has been removed by passing through the existing dry cleaning roller cleaners 230 and 240, and the hole chip has been removed by human inspection and manual operation. However, due to the nature of the sheet-shaped material, the action of removing hole chips by manually shaking the fabric by hand is a cause of increasing work time and increasing defective rate.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 도4와 도5와 같이 공기분사 노즐 및 이송컨베이어부(110,420,430)를 구성하여 연속작업이 가능하게 하고, 탄성력이 있는 벨트를 사용하여 이송중인 판형자재의 상하진동이 용이하게 하고, 공기를 노즐(410)을 통해 펄스방식(S110,S120)으로 이동하는 판형자재(210)에 분사하여 연속된 공기의 분사보다 홀칩 및 먼지를 제거하는 성능이 향상되게하며, 도6와 도9에서 도식한바 같이 펄스방식의 공기분사로 인해 이송중인 판형자재나 시트의 상하 움직임을 주어 가공된 판형자재 또는 시트류의 홀칩 및 이물을 제거하는데 그 목적이 있다.
The present invention is to solve the above problems, as shown in Figs. 4 and 5 to configure the air injection nozzle and the conveying conveyor (110, 420, 430) to enable continuous work, the plate-type being transferred using the belt with elastic force Easily up and down vibration of the material, and by spraying the air to the plate-like material 210 moving in the pulse system (S110, S120) through the nozzle 410, the performance of removing the hole chip and dust than the continuous injection of air is improved As shown in Figures 6 and 9, the purpose is to remove the hole chips and foreign matter of the plate-like material or sheet processed by giving a vertical movement of the plate-like material or sheet being transferred due to the pulsed air injection.

상기의 목적을 달성하기 위한 기술적 사상으로서의 본 발명은, 판형태의 자재나 시트형태의 가공된 원단을 이송하는 컨베이어부(110)와 가공된 판형자재와 시트에 공기를 분사해주는 노즐부(160,410)와 판형자재와 시트에서 분리된 홀칩과 이물을 수거하기 위한 홀칩수거부(130,150)와 각부를 지지해주는 프레임(140)으로 이루어진 것을 특징으로 한다.
The present invention as a technical concept for achieving the above object, the conveyor unit 110 for conveying the plate-shaped material or sheet-like processed fabric and the nozzle portion (160,410) for injecting air to the processed plate-like material and sheet And a hole chip collecting unit 130 and 150 for collecting the hole chip and the foreign matter separated from the sheet-shaped material and the sheet, and a frame 140 supporting each unit.

본 발명에 따른 판형 자재(200,210)나 시트류의 제조과정중 발생하는 홀칩(220)과 이물을 제거하는 세정장치(100)에 의하면, 사람이 수작업으로 시트를 잡고 흔들거나 공기를 가공된 시트에 분사하여 강한 공기흐름을 이용하여 판형자재(210)에 붙어있던 홀칩과 이물을 제거하였지만, 얇은 판형자재(210)의 경우 사람이 붙잡고 공기를 분사하는 경우 수작업으로 인한 판형자재(210)의 구김을 야기 시키므로, 본 발명에 따른 장비는 이송용 컨베이어(110)를 이용하기 때문에 얇은 판형자재(210)가 안정적으로 이송되며, 이송중 공기를 연속분사하지 않고 시간간격(S110)을 두어 분사하여 판형자재(210)에 붙어있는 홀칩(220)과 이물을 직접적으로 제거하고, 시간간격(S110,S120)을 두어 공기를 분사함으로 이송중인 판형자재나 시트류를 도6과 도9와 같이 상하진동시켜 홀칩과 이물을 제거하기 때문에 가공된 판형자재의 손상없이 홀칩과 이물을 제거하고 작업의 흐름도 연속적으로 진행가능해져 세정시간이 단축되는 이점이 있다.
According to the cleaning device 100 for removing the foreign materials and foreign matters during the manufacturing of the plate-like material (200,210) or sheet according to the present invention, a person grabs the sheet by hand or shake the air to the processed sheet Although the hole chip and the foreign matter attached to the plate-like material 210 were removed by using a strong air flow, in the case of the thin plate-like material 210, when the person caught and sprayed air, the wrinkles of the plate-like material 210 due to manual labor were removed. Since the equipment according to the present invention uses the conveyor 110 for transporting, the thin plate-like material 210 is stably transported, and is sprayed at a time interval S110 without continuously spraying air during the transport, and the plate-shaped material. Hole chip 220 attached to the 210 and the foreign matter directly removed, by placing the time interval (S110, S120) by injecting air plate-shaped material or sheet being transported up and down as shown in Figure 6 and Figure 9 There is an advantage that the foreign matter removing holchip without damage of the processed plate material proceeds possible to shorten the cleaning time becomes a flow chart of the operation continuously since the removal of foreign matter.

판형자재(200,210)상의 홀칩(220)과 이물을 제거하는 세정장치는 일반적으로 접촉식 시트 크리닝머신(230,240)을 사용하여 크리닝롤러(230)의 점착력을 이용하여 판형자재(210)에 접촉하여 판형자재는 통과 시키고 홀칩(220)과 이물은 크리닝롤러의 점착력으로 붙잡아 크리닝롤러(230)에 상부와 하부에 접촉하여 회전하는 접착테이프(240)에 전이시켜 제거한다.The cleaning device for removing the hole chips 220 and the foreign matter on the plate-shaped material 200 and 210 is generally in contact with the plate-shaped material 210 by using the adhesive force of the cleaning roller 230 by using the contact sheet cleaning machines 230 and 240. The material is passed through the hole chip 220 and the foreign material is caught by the adhesive force of the cleaning roller to remove the transfer to the rotating adhesive tape 240 in contact with the top and bottom of the cleaning roller 230.

본 발명은 일반적 시트 크리닝머신(230,240)보다 제거율을 높이기 위해 가공된 판형자재(210)의 홀칩(220)과 이물을 일반적 방법인 접촉식 크리닝머신의 방법이 아닌 비접촉식방법으로 공기를 분사하여 제거하는 장비이다.The present invention is to remove the hole chip 220 and the foreign material of the plate-like material 210 processed in order to increase the removal rate than the general sheet cleaning machine (230,240) by spraying air by a non-contact method, not a method of a contact cleaning machine which is a general method It is equipment.

연속 분사되는 공기보다는 시간 간격을 주어 공기를 불연속적으로 분사함으로 제거율을 상승시킬수 있기 때문에 시간조절 가능한 타이머(416)와 공기분사의 개폐를 담당하는 전자식 솔레노이드벨브(418)를 이용하여 펄스방식(S100, S110, S120)의 압축공기를 분사하거나 기계식 차단장치를 이용하여 공기를 펄스방식으로 가공된 판형자재에 분사하여 제거율을 상승시키는 장비이다.또한 펄스방식의 압축공기를 분사할 때 가공된 판형자재의 상하 진동을 더욱 강화시키기 위해 탄성력이 있는 벨트(440)를 채용하여 이송장치부(110)를 구성한 장비이다.Since the removal rate can be increased by discontinuously injecting air at a time interval rather than continuously injecting air, a pulse method using a time adjustable timer 416 and an electronic solenoid valve 418 that is responsible for opening and closing the air injection (S100). This equipment is designed to increase the removal rate by injecting compressed air of S110, S120 or by spraying air on a plate-shaped material processed in a pulse method using a mechanical blocker. In order to further strengthen the up and down vibration of the elastic belt 440 is adopted to configure the transfer unit 110.

목금형틀(260)에 의해 가공된 판형자재(210)를 탄성력이 있는 벨트(440)로 구성된 컨베이어를 통과시키면서 한쪽으로 치우쳐서 노즐(410)을 통해 공기를 분사하면 일차적으로 바람에 힘에 의해 홀칩(220)이 제거되며, 탄성력이 있는 벨트(440)의 반발력에 의해 판형자재의 움직임이 도6과 같이 상하진동에 의해 물결치기 시작한다.Passing the plate-shaped material 210 processed by the wood mold 260 to one side while passing through a conveyor composed of an elastic belt 440, and injecting air through the nozzle 410, primarily by a wind force 220 is removed, the movement of the plate-like material by the repulsive force of the elastic belt 440 begins to wave by vertical vibration as shown in FIG.

이송부 중간에 설치되어 있는 노즐지지대(160)에 정전기 제거장치(470)를 설치하여 정전기에 의한 홀칩과 먼지, 이물등이 판형자재에 붙지 않도록 한다. 정전기제거장치를 통과한후 투입쪽 노즐과 반대방향에서 공기를 펄스방식으로 분사하여 판형자재의 상하진동의 흐름을 역전시켜 상하진동의 물결흐름을 전환시켜 붙어있는 홀칩과 이물을 제거한후 마지막으로 제전성능을 가진 브러쉬(460)를 통과 시키므로 세정작업을 완료한다. 이와같은 펄스방식의 공기분사방식과 그로 인한 상하진동으로 분리시킨 홀칩(220)과 이물은 홀칩수거트레이(130)에서 따라서 홀칩수거박스(150)로 모아지게 된다.The static eliminator 470 is installed on the nozzle support 160 installed in the middle of the conveying part so that the hole chips, dust, and foreign substances due to static electricity do not adhere to the plate-shaped material. After passing through the static eliminator, the air is pulsed in the opposite direction to the nozzle on the inlet side to reverse the flow of up and down vibrations of the plate material, switching the wave flow of the up and down vibrations to remove the stuck hole chips and foreign matters. Since the brush 460 having a performance is passed, the cleaning operation is completed. The hole chip 220 and the foreign matter separated by the air spray method of the pulse method and the vertical vibration resulting therefrom are collected in the hole chip collection box 150 according to the hole chip collection tray 130.
