Coating catch of business drums {Coating catch of business machine drum}

본 발명은 사무기기용 드럼의 코팅 고정장치에 관한 것으로서, 보다 상세하게는 사무용기기에 내설되는 드럼에 코팅제를 코팅시 드럼의 외주면에만 코팅제가 코팅가능하도록 함과 아울러 드럼의 크기에 관계없이 범용으로 사용가능하도록 한 사무기기용 드럼의 코팅 고정장치에 관한 것이다.
The present invention relates to a coating fixing device for a drum for office equipment, and more particularly, when the coating agent is coated on a drum installed in an office equipment, the coating agent can be coated only on the outer circumferential surface of the drum and is generally used regardless of the size of the drum. A coating fixture for an office equipment drum made available.

주지하는 바와 같이 사무용기기 예를 들면, 복사기, 프린터기에는 레이져를 이용하여 문자나 그림 등을 인화시키기 위해 드럼이 내설되어 있다.As is well known, drums are built in office equipment, such as copiers and printers, to print characters or pictures using a laser.

이러한, 드럼은 문서 인쇄시 문서의 질을 결정하게 되는바, 드럼의 표면에는 코팅재가 코팅되어 있다.The drum is to determine the quality of the document when printing the document, the coating of the coating on the surface of the drum.

상기한 드럼의 코팅은 드럼 코팅 고정장치를 이용하여 드럼의 양단을 고정시킨 상태에서 코팅액 저장부로 삽입하여 드럼의 표면을 코팅하게 된다.The coating of the drum is inserted into the coating liquid storage in a state in which both ends of the drum is fixed by using a drum coating fixing device to coat the surface of the drum.

즉, 상기한 드럼 코팅 고정장치는 드럼의 양단을 외측면을 물어 고정할 경우 외측면에 코팅이 균일하게 되지 않으므로 통상적으로 드럼의 내경을 고정하도록 구성되는바, 상기 드럼의 내경으로 삽입되는 척부에 피스톤의 전진 이동에 의해 확관되는 오링이 장착되어, 상기 척부를 드럼의 내경으로 삽입한 후 유압에 의해 피스톤을 움직이면 이 피스톤의 이동에 의해 오링이 확관되고, 확관된 오링이 드럼의 내벽을 밀착 고정하는 것에 의해 드럼을 고정시키게 된다.That is, the drum coating fixing device is generally configured to fix the inner diameter of the drum when the both ends of the drum are fixed to the outer surface, so that the coating is not uniformly formed on the outer surface, the chuck portion inserted into the inner diameter of the drum. The O-ring is expanded by the forward movement of the piston. When the piston is moved by hydraulic pressure after inserting the chuck into the inner diameter of the drum, the O-ring is expanded by the movement of the piston, and the enlarged O-ring tightly fixes the inner wall of the drum. The drum is fixed.

That is, the coating liquid inlet air supply means 170 is formed at a different position from the air supply hole 112 and the air discharge hole 113 formed in the base member 110 is accommodated formed in the base member 110 When the air supplied through the coating liquid inflow preventing air supply hole 171 formed in communication with the groove 115 and the air supplied through the inflow preventing air supply hole 171 is transferred through the piston 120 and the moving bar 130, it is drum. Air guide groove 172 formed on one surface of the fixed connection piece 161 of the cap portion 160 to be sprayed inward, and air formed on the outer peripheral surface of the cap portion 160 to face each other in communication with the air guide groove 172 It consists of injection holes 173.

이와 같이 이루어진 본 발명에 따른 사무기기용 드럼의 코팅 고정장치를 이용하여 드럼을 코팅시키고잘 할 경우에는 첨부된 도면 도 1 내지 도 3에 도시된 바와 같이 먼저, 구조물에 서로 마주 보도록 드럼 코팅장치(100)를 설치한 후, 코팅시키고자 하는 드럼(D)의 양단을 코팅장치(100)의 제1드럼 고정수단(140)까지 각각 삽입시킨다.Coating the drum using the coating fixing device of the office equipment drum according to the present invention thus made, as shown in the accompanying drawings 1 to 3, first, the drum coating device to face each other ( After the installation of 100, both ends of the drum (D) to be coated are inserted into the first drum fixing means 140 of the coating apparatus 100, respectively.

이후, 상기 드럼(D)을 고정시켜 코팅시키고자 베이스부재(110)에 형성된 에어 공급홀(112)을 통하여 에어를 공급한다.Thereafter, air is supplied through the air supply hole 112 formed in the base member 110 to fix and coat the drum D.

상기 에어 공급홀(112)을 통하여 공급된 에어에 의해 상기 베이스부재(110)의 수용홈(115)에 수용된 피스톤(120)은 상기 수용홈(115) 내에서 후향 이동하게 된다.The piston 120 accommodated in the receiving groove 115 of the base member 110 by the air supplied through the air supply hole 112 is moved backward in the receiving groove (115).

상기 피스톤(120)의 이동으로 나사방식으로 일단이 결합된 이동바(130)가 이동하게 된다. As the piston 120 moves, the movement bar 130 having one end coupled to the screw method is moved.

상기 이동바(130)의 이동으로 스크류를 통하여 상기 이동바(130)의 외주면에 형성된 고정요홈(134)에 걸림된 제1드럼 고정수단(140)의 제1가압부재(143)가 이동하게 된다.The first pressing member 143 of the first drum fixing means 140, which is caught in the fixing groove 134 formed on the outer circumferential surface of the moving bar 130 by the movement of the moving bar 130, moves. .

상기 제1가압부재(143)의 이동으로 제1고정부재(141)의 경사면(141b) 끝단에 개재된 제1고정용 오링(142)을 가압시키게 된다.As the first pressing member 143 moves, the first fixing O-ring 142 interposed on the end of the inclined surface 141b of the first fixing member 141 is pressed.

상기 제1가압부재(143)에 가압된 제1고정용 오링(142)은 제1고정부재(141)의 경사면(141b) 측으로 이동하는 것에 의해 확경되어 드럼(D)의 내경을 고정시키게 된다.The first fixing O-ring 142 pressed by the first pressing member 143 is enlarged by moving toward the inclined surface 141b of the first fixing member 141 to fix the inner diameter of the drum D.

물론 이때, 상기 이동바(130) 상에 설치된 제2드럼 고정수단(150)도 함께 이동하게 된다.Of course, at this time, the second drum fixing means 150 installed on the moving bar 130 also moves together.

상기와 같이 드럼(D)이 고정되어 코팅하게 되면, 에어 공급홀(112)을 통하여 공급되는 에어 동시에 코팅액 유입방지용 에어공급수단(170)을 통하여 공급되는 에어에 의해 드럼(D)의 내주면에는 코팅액이 코팅되지 않는다.When the drum (D) is fixed and coated as described above, the coating liquid is coated on the inner circumferential surface of the drum (D) by the air supplied through the air supply hole (112) and the air supplied through the coating liquid inflow preventing air supply means (170). It is not coated.

즉, 상기 에어 공급홀(112)을 통하여 에어를 공급함과 동시에 코팅액 유입방지용 에어공급수단(170)의 유입방지용 에어공급홀(171)을 통하여 에어가 공급되고, 공급된 에어는 베이스부재(110)의 수용홈(115)와 피스톤(120)의 연통홀(123) 그리고, 이동바(130)의 안내홀(133)을 통하여 상기 이동바(130)의 결합나사홈(132)과 나사방식으로 결합된 캡부(160)의 연결편(161)에 형성된 에어안내홈(172)으로 이동되어 상기 에어안내홈(172)과 연통된 에어분사공(173)을 통하여 드럼(D)의 내측으로 공급되므로, 코팅액이 드럼 내측으로 유입하지 못해 드럼의 내주면의 코팅을 방지하게 된다.That is, the air is supplied through the air supply hole 112 and at the same time the air is supplied through the inlet prevention air supply hole 171 of the coating liquid inlet prevention air supply means 170, the supplied air is the base member 110 The receiving groove 115 and the communication hole 123 of the piston 120 and through the guide hole 133 of the moving bar 130 is coupled to the coupling screw groove 132 of the moving bar 130 by a screw method Since it is moved to the air guide groove 172 formed in the connecting piece 161 of the cap portion 160 is supplied to the inside of the drum (D) through the air injection hole 173 in communication with the air guide groove 172, the coating liquid This does not flow into the drum to prevent the coating of the inner peripheral surface of the drum.

한편, 상기와 같이 드럼의 외주면 코팅이 완료되면, 코팅액 유입방지용 에어공급수단(170)을 통하여 공급된 에어와 에어공급홀(112)을 통하여 공급된 에어의 공급을 중단시킨 후, 베이스부재(110)에 형성된 에어 배출홀(113)측으로 에어를 공급시킨다. On the other hand, when the coating of the outer peripheral surface of the drum as described above, after the supply of the air supplied through the air supply means for preventing the air supply means 170 and the coating liquid inlet supply 112 is stopped, the base member 110 Air is supplied to the air discharge hole 113 formed in the).

상기 에어 배출홀(113)을 통하여 에어가 공급되는 것에 의해 피스톤(120)이 수용홈(115) 내에서 전진이동하게 되고, 그로 인하여 이동바(130)와, 상기 이동바(130)에 고정된 제1드럼 고정수단(140)의 제1가압부재(143)가 전진 이동하게 된다.As the air is supplied through the air discharge hole 113, the piston 120 moves forward in the receiving groove 115, whereby the moving bar 130 is fixed to the moving bar 130. The first pressing member 143 of the first drum fixing means 140 is moved forward.

상기 제1가압부재(143)가 전진이동하는 것에 의해 드럼의 내주면을 가압하고 있던 제1고정용 오링(142)도 경사면(141b)을 따라 이동하여 그럼의 내주면을 고정 해제시키게 된다.As the first pressing member 143 moves forward, the first fixing O-ring 142 which presses the inner circumferential surface of the drum also moves along the inclined surface 141b to release the inner circumferential surface thereof.

이후 작업자는 드럼을 코팅장치로부터 이탈시키는 것에 의해 드럼의 코팅이 완료된다.The operator then completes the coating of the drum by removing the drum from the coating apparatus.

그리고, 제2드럼 고정수단(150)을 통하여 직경이 작은 드럼(d)을 코팅시키는 것은 제1드럼 고정수단(140)과 동일한 방법으로 코팅시키는바 이하에서는 상세한 설명은 생략하기로 한다.In addition, the coating of the drum d having a small diameter through the second drum fixing means 150 is coated in the same manner as the first drum fixing means 140, and thus, the detailed description thereof will be omitted.

이상에서 설명한 본 발명은 전술한 실시예 및 첨부된 도면에 의해 한정되는것이 아니고, 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 여러 가지 치환, 변형 및 변경이 가능함은 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자에게 있어서 명백할 것이다.
