진공롤러유닛(A)은 대상물을 이동시키기 위해 연속 회전될 수 있어야 하므로 원형으로 이루어진다. The vacuum roller unit (A) is made in a circular shape because it must be able to be continuously rotated to move the object.

회전동력부(200)는 모터가 적당하다.The rotational power unit 200 is a suitable motor.

모터 중에서 정해진 각도와 회전수를 제한할 수 있는 스텝핑 모터가 적당하다. Among the motors, a stepping motor that can limit a fixed angle and rotation speed is suitable.

회전동력부(200)에서 발생된 회전력은 동력연결부(440)를 통해 회전부(600)에 전달되고, 회전부(600)를 회전시키게 된다. The rotational force generated from the rotational power unit 200 is transmitted to the rotational unit 600 through the power connection unit 440 and rotates the rotational unit 600.

동력연결부(440)는 회전동력부(200)에 형성된 동력전달축(442)과, 동력전달축(442)에 결합된 커플링(444)을 포함하고, 커플링(444)이 바디(400)의 결합공(410)과 억지끼움되도록 커플링(444)이 결합된다. The power connection unit 440 includes a power transmission shaft 442 formed on the rotational power unit 200 and a coupling 444 coupled to the power transmission shaft 442, and the coupling 444 is the body 400 The coupling 444 is coupled so that it is forcibly fitted with the coupling hole 410 of the.

바디(400)는 회전동력부(200)의 동력전달축(442)이 결합되는 결합공(410)이 중심부에 형성되고, 일측에는 중심부와 통하며 개구된 결합구(412)가 형성되어 이루어진다. The body 400 is formed by a coupling hole 410 to which the power transmission shaft 442 of the rotational power unit 200 is coupled is formed in a central portion, and a coupling hole 412 that communicates with the central portion and opens at one side is formed.

커플링(444)의 전단 개구공에 캡(446)이 결합된다. 캡(446)은 회전부(600)의 내부 결합부(640)의 내주면에 삽입된 후 회전부(600)의 전면에 결합된 나사(447)가 관통 체결되어 일체화 되도록 한다. The cap 446 is coupled to the front opening hole of the coupling 444. The cap 446 is inserted into the inner circumferential surface of the inner coupling part 640 of the rotating part 600 and then a screw 447 coupled to the front surface of the rotating part 600 is penetrated to be integrated.

따라서 회전동력부(200)의 회전에 의해 동력전달축(442)의 회전시 커플링(444)과 연결된 회전부(600)가 회전된다. Therefore, when the power transmission shaft 442 is rotated by the rotation of the rotational power unit 200, the rotating unit 600 connected to the coupling 444 is rotated.

바디(400)는 일측에 에어공급포트(462)가 형성되고, 타측에 에어토출포트(464)가 형성되며, 에어공급포트(462)와 에어토출포트(464)를 연결하며 직경이 감소된 에어통로(466)가 형성된다. The body 400 has an air supply port 462 formed on one side, an air discharge port 464 on the other side, and connects the air supply port 462 and the air discharge port 464 to reduce the diameter of air. A passage 466 is formed.

에어통로(466)와 통하도록 진공통로(420)가 형성되며, 진공통로(420)의 단부에 통하도록 흡기공(422)이 형성된다.A vacuum passage 420 is formed to communicate with the air passage 466, and an intake hole 422 is formed to pass through the end of the vacuum passage 420.

이 흡기공(422)은 회전부(600)의 진공홀(620)과 통하도록 형성된다. The intake hole 422 is formed to communicate with the vacuum hole 620 of the rotating part 600.

회전부(600)는 외주연에 원주방향으로 다수 형성된 진공홀(620)이 일정 간격으로 형성되고, 내측 중심부에 결합부(640)가 형성되며, 이 결합부(640)에 캡(446)이 결합되고, 결합부(640)의 외주면과 바디(400)의 결합공(410) 사이에 베어링(680)으로 결합됨으로써 회전부(600)가 안정적으로 회전될 수 있다.In the rotating part 600, a plurality of vacuum holes 620 formed in the circumferential direction on the outer periphery are formed at regular intervals, and a coupling part 640 is formed in the inner center, and the cap 446 is coupled to the coupling part 640 And, by being coupled with the bearing 680 between the outer circumferential surface of the coupling portion 640 and the coupling hole 410 of the body 400, the rotating portion 600 can be stably rotated.

한편 에어공급포트(462)를 통해 고압 공기가 주입된 후 협소한 에어통로(466)를 통과한 후 에어토출포트(464)로 배출된다. Meanwhile, after the high-pressure air is injected through the air supply port 462, it passes through the narrow air passage 466 and is discharged to the air discharge port 464.

이 과정에서 에어통로(466)를 통과하는 동안 유속이 증가되고, 베르누이 정리에 의하여 진공통로(420) 및 진공홀(620)에 흡입력을 발휘하게 된다. In this process, the flow velocity is increased while passing through the air passage 466, and a suction force is exerted on the vacuum passage 420 and the vacuum hole 620 by Bernoulli's theorem.

진공홀(620)의 흡입력에 의해 회전부(600)에 접촉된 대상물(P)을 흡착시키면서 회전부(600)가 회전되므로 대상물(P)의 이탈이 방지될 수 있으면서도 회전부(600)와 대상물(P)의 접촉면적이 진공홀(620)에만 한장될 수 있어 접촉 면적의 최소화로 인해 대상물(P)의 표면 손상을 방지할 수 있다. Since the rotating part 600 is rotated while adsorbing the object P in contact with the rotating part 600 by the suction force of the vacuum hole 620, the separation of the target P can be prevented, while the rotating part 600 and the target P Since the contact area of may be only one sheet in the vacuum hole 620, damage to the surface of the object P may be prevented due to the minimization of the contact area.

한편 상기 에어토출포트(464)에 결합되는 배기관(467)과, 상기 배기관(467)에 연결된 소음기(468)를 포함한다. 따라서 배기관(467)으로 배출된 고압 공기는 소음기(468)를 통과하면서 소음이 소멸되면서 외부로 배출된다. Meanwhile, an exhaust pipe 467 coupled to the air discharge port 464 and a silencer 468 coupled to the exhaust pipe 467 are included. Accordingly, the high-pressure air discharged to the exhaust pipe 467 passes through the silencer 468 and is discharged to the outside while the noise disappears.

비록 바람직한 실시예와 관련하여 설명되어졌지만, 발명의 요지와 범위로부터 벗어남이 없이 다양한 수정 및 변형이 가능한 것은 당업자라면 용이하게 인식할 수 있을 것이며, 이러한 변경 및 수정은 모두 첨부된 청구의 범위에 속함은 자명하다.Although it has been described in connection with the preferred embodiment, it will be easily recognized by those skilled in the art that various modifications and variations are possible without departing from the gist and scope of the invention, and all such changes and modifications fall within the scope of the appended claims. Is self-explanatory.
