본 고안은 판유리를 절단하여 여러 가지 형상으로 가공하거나 절단된 모서리 부위를 매끄럽게 다듬질하는, 판유리 변형면취기에 관한 것으로 특히, 판유리를 흡착, 고정시켜 주는 흡착기 상단에 고무판을 설치하여 흡착기로 이물질이 흡입되는 것을 방지하고, 판유리의 수평유지를 위하여 흡착기의 높이조절을 가능케한, 판유리 변형면취기용 진공 흡착기에 관한 것이다.The present invention relates to a plate glass deformed chamfer that cuts the plate glass into various shapes or smoothes the cut edges. In particular, a foreign matter is sucked into the adsorber by installing a rubber plate on the upper side of the adsorber to adsorb and fix the plate glass. To prevent the height adjustment of the adsorber for horizontal maintenance of the plate glass, and to a vacuum adsorber for flat glass strain chamfering.

일반적으로 판유리를 강공하는 변형면취기는 제1도에서 보는 바와같이 흡입펌프가 내서로딘 몸체(1) 상단에 수직기둥(2)을 고정시켜 회전테이블(3)을 설치하고, 회전테이블(3)상에는 상기 흡입펌프와 통하게 수개의 흡착기(5)를 설치하여 이 흡착기(5)상단에 면취할 판유리(6)를 올려놓고 흡입펌프를 작동시켜 판유리(6)를 진공, 흡착시킨다음, 모터와 연결된 몸체(1) 측방의 다이아 휠(4)을 소정의 베벨각도로 조절하여 판유리(6)를 연마하도록 되어 있는데, 종래에는 제2도의 (a)와 같이 흡착기(5)의 통체(10')상단에 O-링(16)을 고정시켜 이 O-링(16)상에 외부와 밀폐되도록 판유리(6)를 올려놓은 다음 흡입펌프를 작동시켜 흡착고정하였던 겄이다.In general, the deformed chamfering machine for drilling the plate glass, as shown in Figure 1, the suction pump is fixed to the vertical column (2) on the upper end of the body (1) to install the rotary table (3), on the rotary table (3) By installing several adsorbers 5 through the suction pumps, the plate glass 6 to be chamfered is placed on the upper part of the adsorber 5, and the suction pump is operated to vacuum and adsorb the plate glass 6, and then the body connected to the motor. (1) The diaphragm 4 on the side is adjusted to a predetermined bevel angle to polish the plate glass 6. Conventionally, as shown in FIG. 2A, the upper portion of the cylinder 10 'of the adsorber 5 is polished. The O-ring 16 was fixed and the plate glass 6 was placed on the O-ring 16 so as to be sealed to the outside. Then, the suction pump was operated to fix the adsorption.

따라서 이러한 흡착기(5)는 장기간 사용할 경우, O-링(16)이 계속해서 판유리(6)와 접촉함으로서 마모되거나 수축되어 O-링(16)과 판유리(6)사이에 미세한 틈새가 생기게되고, 이로 인하여 면취시 생긴 유리 및 다이아 휠의 가루가 냉각수나 절삭유에 섞여 흡입펌프쪽으로 흡입됨으로서 실린더를 마모시키거나 내부를 부식시켜 펌프의 성능저하와 수명을 단축시키게 되며, 또한 판유리(6)의 수평상태가 틀려짐으로서 사면폭이 불규칙하게 되어 상품가치를 떨어뜨릴 뿐만아니라 회전테이블(3)상에 설치된 각각의 흡착기(5)보다 작은 판유리(6)를 면취할 경우에는 일부 흡착기(5)의 통체(10') 흡입구(10'a)가 열리게되어 이를 별도의 마개로 막아주어야 하는 불편이 뒤따랐다.Therefore, such an adsorber 5 may be worn or shrunk as the O-ring 16 continues to contact the pane 6 when it is used for a long time, resulting in a fine gap between the O-ring 16 and the pane 6, As a result, the glass and diamond wheels generated during chamfering are mixed with cooling water or cutting oil and sucked into the suction pump, which causes the cylinder to wear out or corrode the inside, thereby reducing the performance of the pump and reducing the service life. Of the adsorber 5 is not only lowering the product value and lowering the value of the product, but also chamfering the plate glass 6 smaller than the respective adsorber 5 installed on the rotary table 3. 10 ') the inlet (10'a) was opened, followed by the inconvenience of blocking it with a separate stopper.

이런문제를 해결하기 위하여 최근에는 (나)와 같이 흡착기(5)의 통체(10')내부에 패킹(19)이 부착된 흡입구(10'a)보다 작은 직경의 작동봉(17)를 스프링(18)과 함께 탄설하여 작동봉(17) 선단을 O-링(16)보다 높게 설치함으로서 평상시엔 패킹(19)이 스프링(18)의 탄성력에 의해 흡입구(10'a)를 차단하고 있다가 판유리(6)를 올려놓으면 하중에의해 작동봉(17)이 아래로 내려가면서 흡입구(10'a)가 열리고, 동시에 판유리(6)가 O-링(16)에 밀착되어 흡착, 고정되도록 하고 있으나, 이역시 면취하는 동안에는 계속해서 흡입구(10'a)가 열려있는 상태이므로 이물질의 흡입을 완전히 차단할 수 없는 실정이다.In order to solve this problem, as shown in (b), the operating rod 17 having a diameter smaller than the inlet 10'a having the packing 19 attached to the inside of the cylinder 10 'of the adsorber 5 is spring ( 18) by installing the tip of the operating rod 17 higher than the O-ring 16, the packing 19 normally blocks the suction port 10'a by the elastic force of the spring 18, (6) put the operating rod 17 down by the load inlet (10 'a) is opened, and at the same time the plate glass (6) is in close contact with the O-ring (16), so as to be adsorbed and fixed, In this case, while the inlet 10'a is continuously open, the suction of foreign matter cannot be completely blocked.

본 고안은 이러한 제반 문제점을 해결하기 위하여 흡착기의 통체내부에 고무판이 부착된 작동간을 스프링과 함게 탄설하여 흡입시 고무판의 변형으로 판유리를 흡착, 고정하고, 통체를 위치조절판상의 플랜지와 나사결합시켜 높이조절이 가능하도록 안출한 것으로 첨부된 도면에 의거 상세히 설명하면 다음과 같다.In order to solve the above problems, the present invention installs the rubber plate attached to the inside of the cylinder of the adsorber together with the spring and absorbs and fixes the plate glass by the deformation of the rubber plate during suction, and screwes the cylinder with the flange on the positioning plate. When described in detail based on the accompanying drawings to be possible to adjust the height as follows.

제3도에서 보는 바와 같이 흡착기(5)의 위치조절판(8) 양측에 내부의 흡입통로(8a)와 관통되게 고정흠(8b)을 형성하고, 저면에 돌출부(9a)가 형성된 원통형의 플랜지(9)에는 단턱(9b)이 진 내면상측에 암나사를 형성하며, 외면일측에는 약 7mm 정도의 눈금을 형성하고, 저면의 돌출부(10a)중심에 흡입구(10c)상단을 확개시켜 스프링(13)이 끼워지는 요홈(10d)과 측면이 경사지게 안착호(10e) 및 걸림턱(10f)을 형성하며, 단턱(10g)이진 측면둘레에 수나사를 형성하고, 그 상측에 괘지홈(10i)과 가이드홈(10h)이 형성되게 테두리(10b)를 형성하여 눈금을 형성한다.As shown in FIG. 3, a cylindrical flange 9 having a fixing flaw 8b formed on both sides of the positioning plate 8 of the adsorber 5 so as to penetrate the internal suction passage 8a, and having a protrusion 9a formed on the bottom surface thereof. The upper jaw (9b) is formed on the inner surface of the upper side of the female screw, and on the outer surface one side is formed a scale of about 7mm, and the spring (13) is inserted by expanding the upper end of the suction port (10c) in the center of the projection (10a) of the bottom surface Losing grooves 10d and side surfaces are inclined to form a seating recess (10e) and a locking jaw (10f), stepped (10g) to form a male screw on the side circumference, the hanging groove (10i) and the guide groove (10h) on the upper side ) To form a border (10b) to form a scale.

그리고, 상기 걸림턱(10f)에 안착될수 있도록 측면이 경사지게 작동간(12)을 형성하여 저면에 돌출부(12a)를 형성하며, 측면에 괘지턱(11a)을 갖는 "W"자형상의 고무판(11) 저면에 변형가능하도록 만곡부(11b)를 형성한다.Then, the side is inclined so as to be seated on the engaging jaw (10f) to form the operation section 12 to form a projection (12a) on the bottom, "W" shaped rubber plate 11 having a ruled jaw (11a) on the side The curved part 11b is formed in the bottom surface so that deformation is possible.

조립할대는 먼저, 위치조절판(8)의 양측고정홈(8b)에 플랜지(9)하단의 돌출부(9a)를 끼워 볼트(9')로 체결한 뒤, 플랜지(9)내부에 통체(10)를 나사결합하여 가이드홈(10h)과 플랜지(9) 상단 및 단턱(10g)과 단턱(9b)사이에 여유틈새(α)(β)를 주도록하며, 통체(10)의 요홈(10d)에 스프링을 끼우고, 작동간(12) 상면에 고무판(11)을 부착하여 돌출부(12a)를 스프링(13)상단에 끼운다음, 괘지턱(11a)을 괘지홈(10i)에 끼워 고정시킨다.First, assembling table inserts the projections 9a at the bottom of the flange 9 into the fixing grooves 8b on both sides of the positioning plate 8 and fastens them with bolts 9 ', and then attaches the cylinder 10 to the inside of the flange 9. By screwing together, the clearance gap α (β) is to be provided between the guide groove 10h, the top of the flange 9, and the step 10g and the step 9b, and a spring is provided in the groove 10d of the cylinder 10. The rubber plate 11 is attached to the upper surface of the operation period 12 to insert the protrusion 12a into the upper end of the spring 13, and then the locking jaw 11a is inserted into the locking groove 10i to be fixed.

미설명부호 114, 15는 O-링이고, 7은 흡착기를 회전테이블에 고정시켜주기위한 지지대이다.Reference numerals 114 and 15 are O-rings, and 7 is a support for fixing the adsorber to the rotary table.

상기의 구성에따른 동작과 작용효과를 설명하면 다음과 같다.Referring to the operation and effect according to the above configuration is as follows.

사용자가 흡착기(5)에 판유리(6)를 올려놓게되면, 판유리(6)는 통체(10)상면으로 튀어나온 고무판(11)의 가장자리부분에 밀착된다.When the user puts the plate glass 6 on the adsorber 5, the plate glass 6 is in close contact with the edge of the rubber plate 11 protruding to the upper surface of the cylinder (10).

이 상태에서 제4도와같이 흡입펌프를 작동시키면 흡입펌프의 흡입력이 지지대(7)와 위치조절판(8)의 흡입통로(7a)(8a)를 통해 각 통체(10)의 흡입구(10c)로 전달되어 고무판(11)을 끌어당기게 된다.In this state, when the suction pump is operated as shown in FIG. 4, the suction force of the suction pump is transmitted to the suction port 10c of each cylinder 10 through the suction passages 7a and 8a of the support 7 and the positioning plate 8. Thus, the rubber plate 11 is attracted.

따라서, 고무판(11)은 만곡부(11b)가 펴지면서 가상선과 같은 상태에서 실선과같이 변형되어 고무판(11)과 판유리(6)사이의 압력이 긍갑하하기 때문에 결국 판유리(6)는 고무판(11)에 견고히 흡착 고정되고, 이때, 스프링(13)은 압축되며, 작동간(12)이 걸림턱(10f)에 걸리게되면 더 이상 내려가지 못하고, 동작을 멈추게된다.Therefore, the rubber plate 11 is deformed like a solid line in the same state as the imaginary line while the curved portion 11b is unfolded, so that the pressure between the rubber plate 11 and the plate glass 6 is reduced. ) Is firmly adsorbed and fixed, and at this time, the spring 13 is compressed, and when the operation 12 is caught by the latching jaw 10f, it cannot go further down and stops the operation.

그리고, 판유리(6)의 면취가 완료된 다음에는 흡입펌프의 동작을 멈춘다음, 판유리(6)를 흡착기(5)로부터 들어내면 된다.After the chamfering of the plate glass 6 is completed, the operation of the suction pump may be stopped, and then the plate glass 6 may be lifted from the adsorber 5.

또한 흡착기(5)를 오래사용하여 고무판(11)이 마모되거나 수축되면, 판유리(6)의 수평이 맞지않게되는데, 이때는 통체(10)를 좌, 우회전시켜 눈금을 보면서 각 흡착기(5)의 높낮이를 조절해주면 된다.In addition, when the rubber plate 11 is worn or shrunk by using the adsorber 5 for a long time, the plate glass 6 is not horizontally aligned. At this time, the cylinder 10 is rotated left and right, while watching the scale to raise and lower the height of each adsorber 5. You can adjust it.

이와같이 본 고안은 흡착기(5)의 통체(10)내부에 외부와 밀폐되도록 고무판(11)을 설치하여 이 고무판(11)의 변형에의해 판유리(6)를 흡착, 고정시킴으로서 면취시 생긴 유리 및 다이아휠가루 그리고, 냉각수나 절삭유의 흡입이 완전차단되어 흡입펌프의 수명연장과 성능저하를 방지할수 있고, 통체(10)와 플랜지(9)를 나사결합하여 높이조절이 가능함으로 고무판(11)의 마모나 수축에 의한 판유리(6)의 면취불량을 해결하여 제품고급화와 생산성 향상에 기여할 수 있는 것이다.In this way, the present invention provides a glass and a diamond formed by chamfering by installing a rubber plate 11 so as to be sealed to the outside inside the cylinder 10 of the adsorber 5 by adsorbing and fixing the plate glass 6 by deformation of the rubber plate 11. Wheel powder and cooling water or cutting oil are completely blocked to prevent the extension of the life and performance of the suction pump, and the height can be adjusted by screwing the cylinder 10 and the flange 9 so that the rubber plate 11 is worn out. 2) To solve the chamfering defects of the plate glass (6) due to shrinkage can contribute to the product enhancement and productivity.
