Definitions

  • the present invention relates to a swirl dispenser device for applying a sealer in a swirl form to a body panel or the like.
  • An automobile body is composed of various metal panels and parts. Metal panels or parts can be joined by welding. However, to prevent material deformation due to welding, a method of joining panels using a liquid substance that hardens after application is used. This liquid substance is referred to as a sealer. Sealers can be used to join structural body panels. Sealers can also be used to bond automotive glass to body panels. Sealers applied to panels can be cured by heat or by reacting with moisture in the air, exhibiting properties such as adhesion, sealing, vibration damping, rust prevention, waterproofing, and reinforcing rigidity.
  • the sealer can be applied to the surface of the panel by an application gun.
  • the sealer can be continuously ejected from the application gun and applied to the surface of the panel in a predetermined pattern.
  • Examples of sealer application patterns include a stream pattern, a spot pattern, a bead pattern, and a swirl pattern.
  • the sealer applied in a swirl pattern can fill a wide space between two joint members. Accordingly, in an application example where the sealer needs to be applied in a wide space, an application gun configured to apply the sealer in a swirl pattern can be used.
  • Such a sealer application gun for a swirl pattern must be equipped with a device or mechanism for creating a swirl pattern of the sealer.
  • conventional sealer application guns for swirl patterns are designed with complex structures and are heavy. Furthermore, conventional sealer application guns for swirl patterns are not designed to exhibit good application quality, as they only have devices or mechanisms for creating swirl patterns. Furthermore, conventional sealer application guns for swirl patterns are only suitable for applying sealer to flat panels, and are not easily applied to panels with complex shapes.
  • the present invention was created to solve the above-mentioned problems and needs, and its purpose is to provide a swirl dispenser device capable of applying a sealer continuously and uniformly at regular intervals.
  • a swirl dispenser device is a device for applying a sealer in a swirl form, comprising: a housing into which the sealer is supplied and which has a stator therein; a rotor shaft which has a rotor interacting with the stator and is coupled to the inside of the housing to rotate around a rotational axis and which is formed hollow; a hollow sealer shaft having a first spherical rotary port fixed to one end through which the sealer is introduced and inserted into the inside of the housing, a nozzle for spraying the sealer is formed at the other end, and which is formed to penetrate the rotor shaft along the rotational axis; a first holder which is seated on one side of the inside of the housing coaxially with the rotational axis and receives the first rotary port; and a second holder which is fixed to the rotor shaft coaxially with the rotational axis and supports the other side of the sealer shaft and eccentric
  • the first rotating member is supported by receiving it in a concave shape, and the second holder is coupled to enable tilting rotation, and the outer surface of the other side of the sealer shaft is supported by a bearing that is eccentric in a direction orthogonal to the rotation axis.
  • a first spherical rotating ball is accommodated inside the housing and is capable of three-dimensional point (ball) rotation without bending, thereby solving the conventional problem and providing the advantage of being able to continuously and uniformly apply a sealer at regular intervals.
  • sealer filled in the space within the sealer shaft acts as a buffer, so it controls the sealer opening and closing part that is spaced apart without being easily affected by temperature changes, so there is an advantage in that it can effectively block the open nozzle.
  • the second rotary member (232) having an outer surface in the shape of a sphere or ellipsoid can be freely rotated in three dimensions like a joystick while being accommodated in the second holder, thereby complementing the sealer shaft of the first embodiment.

Description

스월 디스펜서 장치Swirl dispenser device

본 발명은 차체용 패널 등에 실러를 스월(swerl) 형태로 도포하는 스월 디스펜서 장치에 관한 것이다.The present invention relates to a swirl dispenser device for applying a sealer in a swirl form to a body panel or the like.

이하에서 기술되는 내용은 본 실시예에 대한 배경 정보를 제공할 뿐 종래기술을 기재한 것은 아니다.The content described below only provides background information for the present embodiment and does not describe prior art.

자동차의 차체는 다양한 금속재의 패널들과 금속재의 부품들로 이루어진다. 금속재의 패널 또는 부품들은 용접에 의해 접합될 수 있다. 그러나, 용접으로 인한 소재의 변형을 방지하기 위해, 도포 후 경화되는 액상 물질에 의해 패널들을 접합하는 방식이 사용되고 있다. 이러한 액상 물질은 실러(sealer)로서 참조된다. 실러는 차체용 구조 패널들의 접합에 사용될 수 있다. 실러는 자동차 유리와 차체용 패널의 접합에 사용될 수 있다. 패널에 도포된 실러는, 열에 의해 경화되거나, 공기 중의 습기와 반응하여 경화되어, 접착, 밀봉, 제진, 방청, 방수, 강성 보강 등의 특성을 나타낼 수 있다.An automobile body is composed of various metal panels and parts. Metal panels or parts can be joined by welding. However, to prevent material deformation due to welding, a method of joining panels using a liquid substance that hardens after application is used. This liquid substance is referred to as a sealer. Sealers can be used to join structural body panels. Sealers can also be used to bond automotive glass to body panels. Sealers applied to panels can be cured by heat or by reacting with moisture in the air, exhibiting properties such as adhesion, sealing, vibration damping, rust prevention, waterproofing, and reinforcing rigidity.

실러는 패널의 표면에 도포 건에 의해 도포될 수 있다. 실러는 도포 건으로부터 연속적으로 분출되어 소정의 패턴으로 패널의 표면에 도포될 수 있다. 실러를 도포하는 패턴의 예로서, 줄 패턴(stream pattern), 점 패턴(spot pattern), 비드 패턴(bead pattern), 스월 패턴(swirl pattern) 등이 알려져 있다. 스월 패턴으로 도포된 실러는, 두개의 접합 부재 사이에 넓은 폭으로 채워질 수 있다. 이에 따라, 실러가 넓은 폭으로 도포될 필요가 있는 도포 예에서는, 스월 패턴으로 실러를 도포하도록 구성되는 도포 건이 사용될 수 있다. 이러한 스월 패턴용 실러 도포 건은, 실러의 스월 패턴을 생성하기 위한 장치 또는 기구를 구비해야 한다.The sealer can be applied to the surface of the panel by an application gun. The sealer can be continuously ejected from the application gun and applied to the surface of the panel in a predetermined pattern. Examples of sealer application patterns include a stream pattern, a spot pattern, a bead pattern, and a swirl pattern. The sealer applied in a swirl pattern can fill a wide space between two joint members. Accordingly, in an application example where the sealer needs to be applied in a wide space, an application gun configured to apply the sealer in a swirl pattern can be used. Such a sealer application gun for a swirl pattern must be equipped with a device or mechanism for creating a swirl pattern of the sealer.

종래의 스월 패턴용 실러 도포 건은, 상기 장치 또는 기구를 도포 건에 구비시키는 관점에서만 설계되어 있다.Conventional sealer application guns for swirl patterns are designed only from the perspective of equipping the application gun with the above device or mechanism.

이에 따라, 종래의 스월 패턴용 실러 도포 건은 복잡한 구조로 설계되고 있으며 고중량을 갖는다. 또한, 종래의 스월 패턴용 실러 도포 건은 스월 패턴의 생성용의 장치 또는 기구를 구비할 뿐, 양호한 도포 품질을 나타내도록 설계되어 있지 않다. 또한, 종래의 스월 패턴용 실러 도포 건은, 평판의 패널에 실러를 도포하는데에 적합할 뿐, 복잡한 형상을 갖는 패널에는 용이하게 적용되지 못한다.Accordingly, conventional sealer application guns for swirl patterns are designed with complex structures and are heavy. Furthermore, conventional sealer application guns for swirl patterns are not designed to exhibit good application quality, as they only have devices or mechanisms for creating swirl patterns. Furthermore, conventional sealer application guns for swirl patterns are only suitable for applying sealer to flat panels, and are not easily applied to panels with complex shapes.

이러한 문제점을 해결하고자 특허등록번호 제10-2346348호인 스월 실러 도포 건 및 이를 포함하는 스월 실러 도포 장치가 도 1에 도시된 바와 같이, 개시된 바 있다. 하지만, 선행 기술도 도 2와 같이 실러를 연속적이고 균일하게 일정한 간격으로 도포하기에는 한계가 있다.To solve these problems, a swirl sealer application gun and a swirl sealer application device including the same, patented under patent registration number 10-2346348, have been disclosed as shown in Fig. 1. However, the prior art also has limitations in applying the sealer continuously and uniformly at regular intervals, as shown in Fig. 2.

본 발명은 상기한 문제점 및 필요성을 해결하기 위하여 창출된 것으로, 실러를 연속적이고 균일하게 일정한 간격으로 도포할 수 있는 스월 디스펜서 장치를 제공하는 데 그 목적이 있다.The present invention was created to solve the above-mentioned problems and needs, and its purpose is to provide a swirl dispenser device capable of applying a sealer continuously and uniformly at regular intervals.

상기한 목적을 달성하기 위하여, 본 발명의 제1 실시 예에 따른 스월 디스펜서 장치는 스월(swerl) 형태로 실러를 도포하는 장치로, 상기 실러가 공급되고 내부에 고정자를 갖는 하우징과, 상기 고정자와 상호 작용하는 회전자를 갖고 상기 하우징의 내부에 회전축을 중심으로 회전되도록 결합되며 중공으로 형성된 로터샤프트와, 상기 실러가 유입되어 상기 하우징의 내부로 삽입되는 일단에 구체 형상의 제1 회동구가 고정되고 상기 실러를 분출하는 노즐이 타단에 형성되며 상기 회전축을 따라 상기 로터샤프트를 관통하도록 형성된 중공의 실러샤프트와, 상기 회전축과 동축으로 상기 하우징의 내부 일측에 안착되어 상기 제1 회동구를 수용하는 제1 홀더, 및 상기 회전축과 동축으로 상기 로터샤프트에 고정되어 상기 실러샤프트 타측을 지지하고 상기 실러샤프트를 상기 회전축을 따라 경사지게 상기 노즐을 상기 회전축으로부터 편심시키는 제2 홀더를 포함하고, 상기 제1 홀더는 상기 제1 회동구를 요입(凹入) 형상으로 수용하여 지지하되 상기 제1 회동구가 틸팅(tilting) 회동 가능하게 결합되며, 상기 제2 홀더는 상기 실러샤프트 타측의 외주면을 지지하되 상기 회전축에 직교하는 방향으로 편심되어 있는 베어링으로 결합된다.In order to achieve the above object, a swirl dispenser device according to a first embodiment of the present invention is a device for applying a sealer in a swirl form, comprising: a housing into which the sealer is supplied and which has a stator therein; a rotor shaft which has a rotor interacting with the stator and is coupled to the inside of the housing to rotate around a rotational axis and which is formed hollow; a hollow sealer shaft having a first spherical rotary port fixed to one end through which the sealer is introduced and inserted into the inside of the housing, a nozzle for spraying the sealer is formed at the other end, and which is formed to penetrate the rotor shaft along the rotational axis; a first holder which is seated on one side of the inside of the housing coaxially with the rotational axis and receives the first rotary port; and a second holder which is fixed to the rotor shaft coaxially with the rotational axis and supports the other side of the sealer shaft and eccentrically rotates the sealer shaft along the rotational axis, and the first holder is configured to rotate the first rotary port. The first rotating member is supported by receiving it in a concave shape, and the second holder is coupled to enable tilting rotation, and the outer surface of the other side of the sealer shaft is supported by a bearing that is eccentric in a direction orthogonal to the rotation axis.

본 발명에 따르면, 구체 형상의 제1 회동구가 하우징의 내부에 수용되어 휘지 않고 3차원 점(ball)회동이 가능하여, 종래의 문제점을 해결하면서 실러를 연속적이고 균일하게 일정한 간격으로 도포할 수 있는 이점이 있다.According to the present invention, a first spherical rotating ball is accommodated inside the housing and is capable of three-dimensional point (ball) rotation without bending, thereby solving the conventional problem and providing the advantage of being able to continuously and uniformly apply a sealer at regular intervals.

또한, 실러샤프트 내의 공간에 충진된 실러가 완충 작용을 하여 온도 변화에 쉽게 영향을 받지 않으면서 이격되어 있는 실러개폐부를 제어하므로 오픈된 노즐을 효과적으로 단속할 수 있는 이점이 있다.In addition, the sealer filled in the space within the sealer shaft acts as a buffer, so it controls the sealer opening and closing part that is spaced apart without being easily affected by temperature changes, so there is an advantage in that it can effectively block the open nozzle.

또한, 외주면이 구체(sphere) 또는 타원체 형상의 제2 회동구(232)가 제2 홀더에 수용된 상태에서 조이스틱처럼 자유롭게 3차원 틸팅 회동이 가능하여 제1 실시 예의 실러샤프트를 보완할 수 있는 이점이 있다.In addition, there is an advantage in that the second rotary member (232) having an outer surface in the shape of a sphere or ellipsoid can be freely rotated in three dimensions like a joystick while being accommodated in the second holder, thereby complementing the sealer shaft of the first embodiment.

또한, 상기 제1 홀더(140)는 상기 제1 회동구(131)를 요입(凹入) 형상으로 수용하여 지지하되 상기 제1 회동구(131)가 틸팅(tilting) 회동 가능하게 결합되며, 상기 제2 홀더(150)는 상기 실러샤프트(130) 타측의 외주면을 지지하되 상기 회전축(RY)에 직교하는 방향으로 편심되어 있는 베어링(151)으로 결합될 수 있다.In addition, the first holder (140) may be configured to receive and support the first rotary member (131) in a recessed shape, and the first rotary member (131) may be coupled to be capable of tilting rotation, and the second holder (150) may be coupled to a bearing (151) that supports the outer surface of the other side of the sealer shaft (130) and is eccentric in a direction orthogonal to the rotation axis (RY).

또한, 상기 제1 홀더(140)는 양팔을 벌리듯 한쌍의 유도부재(141)가 상기 제1 회동구(131) 외주면을 소정 높이로 감싸되 상기 한쌍의 유도부재(141) 사이로 단면이 "ㅓ"자 형상의 링부재(142)가 상기 제1 회동구(131) 외측방을 지지할 수 있다.In addition, the first holder (140) has a pair of inductive members (141) that wrap around the outer surface of the first rotary member (131) at a predetermined height as if spreading out two arms, and a ring member (142) with a cross-section shaped like the letter "ㅓ" between the pair of inductive members (141) can support the outer side of the first rotary member (131).

또한, 상기 제2 홀더(150)는 상기 제1 회동구(131)로부터 상기 제2 홀더(150)를 향하여 상기 실러샤프트(130)의 편심량(EY)이 커지도록 상기 실러샤프트(130)를 경사지게 할 수 있다.In addition, the second holder (150) can incline the sealer shaft (130) so that the eccentricity (EY) of the sealer shaft (130) increases from the first rotary member (131) toward the second holder (150).

또한, 상기 베어링(151)은 상기 회전축(RY)을 중심으로 하는 상기 실러샤프트(130)의 원운동을 허용하도록 구성될 수 있다.Additionally, the bearing (151) may be configured to allow circular motion of the sealer shaft (130) centered on the rotation axis (RY).

또는, 상기 베어링(151)은 상기 제1 회동구(131)를 중심으로 하는 상기 실러샤프트(130)의 원추(원뿔)운동을 허용하도록 구성될 수 있다.Alternatively, the bearing (151) may be configured to allow a conical motion of the sealer shaft (130) centered on the first rotary member (131).

또한, 상기 실러샤프트(130) 내로 연통되게 형성된 실러유로(161)를 실러밸브(162)로 개폐하는 실러개폐부(160)를 더 포함할 수 있다.In addition, a sealer opening/closing unit (160) that opens/closes a sealer passage (161) formed to be connected to the sealer shaft (130) by a sealer valve (162) may be further included.

또한, 상기 실러개폐부(160)는 실러 도포시 상기 실러밸브(162)가 상기 실러유로(161)를 개방시켜 상기 실러샤프트(130) 내의 압력이 대기압보다 높게 유지시키고, 실러 도포 중단시 상기 실러샤프트(130) 내의 실러를 스닢(sniff, 코로 코물을 훔치듯이) 흡입하여 상기 실러유로(161)를 폐쇄시켜 상기 실러샤프트(130) 내의 압력이 대기압보다 낮게 할 수 있다.In addition, the sealer opening/closing unit (160) can open the sealer passage (161) by the sealer valve (162) when applying the sealer to maintain the pressure within the sealer shaft (130) higher than the atmospheric pressure, and when application of the sealer is stopped, the sealer within the sealer shaft (130) can be sucked in (like sniffing snot with the nose) to close the sealer passage (161) to make the pressure within the sealer shaft (130) lower than the atmospheric pressure.

즉, 상기 실러개폐부(160)는 실러 도포시 상기 실러밸브(162)가 상기 실러유로(161)를 개방시켜 상기 실러샤프트(130) 내의 압력이 대기압보다 높게 유지되므로, 상기 노즐(133)로 상기 실러(SL)를 분출시키고, 실러 도포 중단시 상기 실러샤프트(130) 내의 실러(SL)를 스닢(sniff, 코로 코물을 훔치듯이) 흡입하여 상기 실러유로(161)를 폐쇄시켜 상기 실러샤프트(130) 내의 압력이 대기압보다 낮아지므로, 주위보다 낮아지는 부압(negative pressure)이 발생하여 상기 노즐(133)로부터 상기 실러(SL)가 흘러내지지 않게 방지할 수 있다.That is, when the sealer is applied, the sealer opening/closing unit (160) opens the sealer passage (161) by the sealer valve (162) so that the pressure inside the sealer shaft (130) is maintained higher than the atmospheric pressure, thereby ejecting the sealer (SL) through the nozzle (133), and when the sealer application is stopped, the sealer (SL) inside the sealer shaft (130) is sucked in (as if wiping mucus with the nose) so that the sealer passage (161) is closed, so that the pressure inside the sealer shaft (130) is lower than the atmospheric pressure, thereby generating a negative pressure lower than the surroundings, thereby preventing the sealer (SL) from flowing out from the nozzle (133).

그럼, 본 발명의 실시 예들에 따른 스월 디스펜서 장치(100, 200)의 구성 및 동작을 구체적으로 설명하면 다음과 같다.Then, the configuration and operation of the swirl dispenser device (100, 200) according to embodiments of the present invention will be described in detail as follows.

본 발명의 제1 실시 예에 따른 스월 디스펜서 장치(100)는 도 3에 도시된 바와 같이, 스월(swerl) 형태로 실러(sealer or sealant)를 도포하는 장치로, 하우징(110)과, 로터샤프트(120)와, 실러샤프트(130)와, 제1 홀더(140), 및 제2 홀더(150) 등을 포함한다.A swirl dispenser device (100) according to a first embodiment of the present invention is a device for applying a sealer (sealer or sealant) in a swirl form, as illustrated in FIG. 3, and includes a housing (110), a rotor shaft (120), a sealer shaft (130), a first holder (140), a second holder (150), etc.

하우징(110)은 본 발명이 제안하는 스월 디스펜서 장치(100)의 몸체를 구성하여 그 내부에 실러(SL)의 분출과 스월 패턴(swerl pattern) 생성을 위한 구성요소들을 수용한다. 실러(SL)는 실러공급원(미도시)으로부터 하우징(110) 내에 형성된 유로를 따라 공급된다.The housing (110) constitutes the body of the swirl dispenser device (100) proposed by the present invention and houses components for ejecting the sealer (SL) and creating a swirl pattern therein. The sealer (SL) is supplied from a sealer supply source (not shown) along a path formed within the housing (110).

하우징(110)은 회전력을 발생시키는 모터의 구성요소로서, 내부에 고정자(111)를 갖는다. 고정자(111)는 후술할 회전자(121) 외측에 위치하며 링(ring) 형상이다. 고정자(111)는 하우징(110)에 부착된 전원커넥터(미도시)를 통해 전원으로부터 전력을 공급받는다. 한편, 하우징(110)은 조립하거나 해체하여 보수하기 용이하게 복수의 블럭(block)으로 구성될 수 있고, 상호 수밀 또는 기밀하게 결합될 수 있다.The housing (110) is a component of a motor that generates rotational force and has a stator (111) therein. The stator (111) is located outside a rotor (121) to be described later and has a ring shape. The stator (111) receives power from a power source through a power connector (not shown) attached to the housing (110). Meanwhile, the housing (110) may be composed of a plurality of blocks for easy maintenance by assembling or disassembling, and may be watertightly or airtightly coupled to each other.

로터샤프트(120)는 도 3에 도시된 바와 같이, 고정자(111)와 상호 작용하는 회전자(121)를 갖고 하우징(110)의 내부에 회전축(RY)을 중심으로 회전되도록 결합되는 샤프트(shaft)부재이다.As shown in Fig. 3, the rotor shaft (120) is a shaft member that has a rotor (121) that interacts with a stator (111) and is coupled to rotate around a rotation axis (RY) inside the housing (110).

즉, 로터샤프트(120)는 회전력을 발생시키는 모터의 또 하나의 구성요소로, 그 안에 실러(SL)를 분출하기 위해 기능하는 실러샤프트(130) 등의 구성요소들을 수용한다. 로터샤프트(120)는 중공으로 형성된 중공의 샤프트(shaft)이다. 로터샤프트(120)는 하우징(110)의 내부에 회전축(RY)을 중심으로 회전하도록 결합되어 있다. 상기 회전축(RY)은 중공인 로터샤프트(120)의 내부를 통해 연장하고 로터샤프트(120)의 회전의 중심이 되는 가상의 회전축(Rotation Y axis)을 의미한다. 이때, 로터샤프트(120)는 하우징(110) 내에서 베어링에 의해서 지지되어 회동할 수 있다.That is, the rotor shaft (120) is another component of the motor that generates rotational force, and houses components such as a sealer shaft (130) that functions to spray a sealer (SL) therein. The rotor shaft (120) is a hollow shaft formed hollow. The rotor shaft (120) is coupled to rotate around a rotation axis (RY) inside the housing (110). The rotation axis (RY) means a virtual rotation axis (Rotation Y axis) that extends through the inside of the hollow rotor shaft (120) and becomes the center of rotation of the rotor shaft (120). At this time, the rotor shaft (120) can rotate while being supported by a bearing inside the housing (110).

또한, 상기 베어링은 로터샤프트(120)의 외주면에 결합되어 로터샤프트(120)를 회전축(RY)을 중심으로 회전 가능하게 지지할 수 있다.In addition, the bearing is coupled to the outer surface of the rotor shaft (120) and can support the rotor shaft (120) so that it can rotate around the rotation axis (RY).

한편, 본 발명에서는 회동이 원활하도록 다수의 베어링을 사용하고 있으나, 상기 베어링 중 특징적인 기능이 있는 것에 대해서만 부호를 부여하여 자세히 설명하고 나머지는 부호를 부여하지 않고 간단히 설명한다.Meanwhile, in the present invention, a number of bearings are used to ensure smooth rotation, but only bearings with characteristic functions among the bearings are described in detail by assigning symbols, and the rest are described simply without assigning symbols.

로터샤프트(120)는 그 외주에 둘레방향으로 배치된 회전자(121)를 갖는다. 이때 하우징(110)은 회전자(121)가 구비된 로터샤프트(120)를 수용한다. 스월 디스펜서 장치(100)에 전력이 공급되면, 회전자(121)는 고정자(111)와 상호 작용하여 로터샤프트(120)를 회전시키는 회전력을 발생시킨다. 이와 같이, 스월 디스펜서 장치(100)는 고정자(111)와 회전자(121)에 의해 모터 작용을 실행한다.The rotor shaft (120) has a rotor (121) arranged circumferentially on its outer periphery. At this time, the housing (110) accommodates the rotor shaft (120) equipped with the rotor (121). When power is supplied to the swirl dispenser device (100), the rotor (121) interacts with the stator (111) to generate a rotational force that rotates the rotor shaft (120). In this way, the swirl dispenser device (100) performs a motor function by the stator (111) and the rotor (121).

실러샤프트(130)는 도 3에 도시된 바와 같이, 실러(SL)가 유입되고 하우징(110)의 내부로 삽입되는 일단에 고정된 구체 또는 볼(ball) 형상의 제1 회동구(131)와 실러(SL)를 분출하는 노즐(133)이 타단에 형성되고 회전축(RY)을 따라 로터샤프트(120)를 관통하도록 형성된 중공의 샤프트(shaft)부재이다.As shown in Fig. 3, the sealer shaft (130) is a hollow shaft member having a first rotary port (131) in the shape of a sphere or ball fixed at one end through which the sealer (SL) is introduced and inserted into the interior of the housing (110) and a nozzle (133) for spraying the sealer (SL) formed at the other end and formed to penetrate the rotor shaft (120) along the rotation axis (RY).

즉, 실러샤프트(130)는 중공으로 형성되어 있다. 실러샤프트(130)는 실러유로(161)로부터 공급된 실러(SL)를 수용하고, 도포 작업 시에 실러(SL)를 분출한다. 실러샤프트(130)는 로터샤프트(120)의 회전축(RY)을 따르는 길이보다 긴 길이를 가진다. 실러샤프트(130)는 회전축(RY)을 따라 로터샤프트(120)를 관통하도록 형성되고, 실러샤프트(130)가 로터샤프트(120)의 내부에 배치된다.That is, the sealer shaft (130) is formed hollow. The sealer shaft (130) receives the sealer (SL) supplied from the sealer channel (161) and sprays the sealer (SL) during the application process. The sealer shaft (130) has a length longer than the length along the rotation axis (RY) of the rotor shaft (120). The sealer shaft (130) is formed to penetrate the rotor shaft (120) along the rotation axis (RY), and the sealer shaft (130) is arranged inside the rotor shaft (120).

실러샤프트(130)는 하우징(110) 내에 타단이 자유단이 되는 내민보(Single overhanging beam)의 형태로, 상하 높이(승강) 방향으로 배치된다. 즉, 실러샤프트(130)는 일단에 회동볼(ball)처럼 3차원 회동이 가능하도록 구체 또는 볼(bal1) 형상의 제1 회동구(131)가 장착되고, 타단에 자유단을 가지되 실러(SL)를 분출하는 노즐(133)이 형성된다.The sealer shaft (130) is arranged in the vertical height (lifting) direction in the form of a single overhanging beam with the other end being a free end within the housing (110). That is, the sealer shaft (130) is equipped with a first rotary member (131) in the shape of a sphere or ball (bal1) to enable three-dimensional rotation like a rotary ball at one end, and a nozzle (133) having a free end and spraying a sealer (SL) is formed at the other end.

즉, 실러샤프트(130) 자유단인 타단에는 실러(SL)를 분출하는 노즐(133)이 형성되어 있다. 실러샤프트(130)는 노즐(133)이 로터샤프트(120)로부터 돌출하도록 구성된다. 노즐(133)이 형성된 실러샤프트(130) 타단은 하우징(110)으로부터 회전축(RY)을 따라 돌출한다. 실러샤프트(130) 타단은 로터샤프트(120)의 하단으로부터 돌출한다. 돌출한 실러샤프트(130) 타단은 하우징(110)과 접촉하지 않는다.That is, a nozzle (133) for spraying a sealer (SL) is formed at the other end, which is the free end of the sealer shaft (130). The sealer shaft (130) is configured so that the nozzle (133) protrudes from the rotor shaft (120). The other end of the sealer shaft (130) on which the nozzle (133) is formed protrudes from the housing (110) along the rotation axis (RY). The other end of the sealer shaft (130) protrudes from the lower end of the rotor shaft (120). The other end of the protruding sealer shaft (130) does not contact the housing (110).

또한, 실러샤프트(130)는 중공의 내부 빈 공간에 실러(SL)가 충진되어 내부압에 따라 오픈된 노즐(133)을 통하여 상기 실러(SL)가 분출될 수 있게 한다.In addition, the sealer shaft (130) is filled with a sealer (SL) in the hollow internal space so that the sealer (SL) can be ejected through an open nozzle (133) according to the internal pressure.

이때, 실러샤프트(130)의 자유단에 형성된 노즐(133)은 회전축(RY)으로부터 편심되어 있다. 이에 따라, 로터샤프트(120)가 회전하면, 노즐(133)은 로터샤프트(120)의 회전축(RY)을 중심으로 하여 원운동을 실행한다. 로터샤프트(120)와 실러샤프트(130) 타측에 배치되는 후술할 제2 홀더(150)가 노즐(133)을 편심시킨다.At this time, the nozzle (133) formed at the free end of the sealer shaft (130) is eccentric from the rotation axis (RY). Accordingly, when the rotor shaft (120) rotates, the nozzle (133) performs a circular motion centered on the rotation axis (RY) of the rotor shaft (120). The second holder (150) described later, which is arranged on the other side of the rotor shaft (120) and the sealer shaft (130), eccentricizes the nozzle (133).

한편, 종래의 실러 샤프트(1300)는 도 1에 도시된 바와 같이, 고정단부(1310)와 자유단부(1320)를 갖고, 고정단부(1310)는 하우징(1100)의 내부에 고정되어 있기 때문에 편심 부재(1400)에 의해 실러 샤프트(1300)는 회전축(RA)을 따라 휘어진다.Meanwhile, as shown in FIG. 1, the conventional sealer shaft (1300) has a fixed end (1310) and a free end (1320), and since the fixed end (1310) is fixed inside the housing (1100), the sealer shaft (1300) is bent along the rotation axis (RA) by the eccentric member (1400).

따라서, 종래의 실러 샤프트(1300)는 고정단부(1310)로부터 편심 부재(1400)를 향하여 점차 휘어지고, 편심 부재(1400)가 회전함에 따라, 회전축(RA)에 대하여 휜 상태로, 원형의 궤적을 따라 이동되면서 비틀리어 변형될 수 있다.Accordingly, the conventional sealer shaft (1300) gradually bends from the fixed end (1310) toward the eccentric member (1400), and as the eccentric member (1400) rotates, it can be twisted and deformed while moving along a circular trajectory in a bent state with respect to the rotation axis (RA).

이로 인하여, 종래의 실러 샤프트(1300)는 탄성에너지가 내부에 축적되다가 한계치에 도달하게 되면, 소성 변형되거나 표출하여 실러 도포가 일정하지 못하고 스타카토처럼 끊기거나 불규칙하게 되어, 도 2와 같이 지속적이고 균일한 도포를 실현할 수 없었다.Due to this, when elastic energy accumulates inside the conventional sealer shaft (1300) and reaches a limit, it is plastically deformed or expressed, so that the sealer application is not uniform and is cut off or irregular like a staccato, making it impossible to achieve continuous and uniform application as shown in Fig. 2.

반면, 본 발명이 제안하는 실러샤프트(130)는 도 3의 (a)에 도시된 바와 같이, 구체 또는 볼(ball) 형상의 제1 회동구(131)가 하우징(110)의 내부에 수용되어 휘지 않고 3차원 점(ball)회동이 가능하여, 종래의 문제점을 해결하면서 도 2와 같이 실러(SL)를 연속적이고 균일하게 일정한 간격으로 도포할 수 있다.On the other hand, the sealer shaft (130) proposed by the present invention, as shown in (a) of FIG. 3, has a first rotary member (131) in the shape of a sphere or ball accommodated inside the housing (110) so as to be capable of three-dimensional point (ball) rotation without bending, thereby solving the problems of the prior art and allowing the sealer (SL) to be applied continuously and uniformly at regular intervals as shown in FIG. 2.

제1 홀더(140)는 실러샤프트(130) 일단을 잡아주는 부재로, 회전축(RY)과 동축으로 하우징(110)의 내부 일측에 안착되어 제1 회동구(131)를 수용하는 지지공간을 제공할 수 있다.The first holder (140) is a member that holds one end of the sealer shaft (130), and can be installed on one side of the inside of the housing (110) coaxially with the rotation axis (RY) to provide a support space for accommodating the first rotary member (131).

특히, 제1 홀더(140)는 제1 회동구(131)가 3차원 틸팅 회동이 가능하도록 지지하는데, 상기 제1 회동구(131)를 요입(凹入) 형상으로 수용하여 지지하되 상기 제1 회동구(131)가 틸팅(tilting) 회동 가능하게 결합될 수 있다.In particular, the first holder (140) supports the first rotary member (131) so that it can rotate in a three-dimensional tilting manner. The first rotary member (131) is supported by receiving it in a concave shape, and the first rotary member (131) can be coupled so that it can rotate in a tilting manner.

또한, 제1 홀더(140)는 도 3의 (a)에 도시된 바와 같이, 양팔을 벌리듯 한쌍의 유도부재(141)가 제1 회동구(131) 외주면을 소정 높이로 감싸되, 상기 한쌍의 유도부재(141) 사이로 단면이 "ㅓ"자 형상의 링부재(142)가 상기 제1 회동구(131) 외측방을 지지하여 상기 제1 회동구(131)와 접촉을 최소화하여 회동 저항(마찰)이 적어지므로, 수용된 공간에서 자유롭게 3차원 회동이 가능하게 한다.In addition, as shown in (a) of FIG. 3, the first holder (140) has a pair of inductive members (141) that wrap around the outer surface of the first rotary member (131) at a predetermined height, as if spreading out two arms, and a ring member (142) having a cross-section in the shape of the letter "ㅓ" between the pair of inductive members (141) supports the outer side of the first rotary member (131), minimizing contact with the first rotary member (131) and reducing rotational resistance (friction), thereby enabling free three-dimensional rotation in the accommodated space.

제2 홀더(150)는 도 3에 도시된 바와 같이, 로터샤프트(120)의 하단부(타단)에 고정 및 결합되고, 로터샤프트(120)에 회전축(RY)과 동축으로 회전하도록 고정된다.The second holder (150) is fixed and coupled to the lower end (other end) of the rotor shaft (120), as shown in FIG. 3, and is fixed to rotate coaxially with the rotation axis (RY) of the rotor shaft (120).

제2 홀더(150)는 로터샤프트(120)의 하단부의 외주면과 결합되는 링 형상으로, 실러샤프트(130)와 슬라이드 가능한 접촉을 하여, 상기 실러샤프트(130)를 지지한다. 제2 홀더(150)는 실러샤프트(130)를 회전축(RY)에 직교하는 방향으로 소정의 편심량(EY)만큼 편심시키도록 구성된다.The second holder (150) is a ring-shaped member that is coupled to the outer surface of the lower end of the rotor shaft (120), and supports the sealer shaft (130) by making slidable contact with it. The second holder (150) is configured to eccentrically move the sealer shaft (130) by a predetermined amount of eccentricity (EY) in a direction perpendicular to the rotation axis (RY).

즉, 제2 홀더(150)의 영역에서 실러샤프트(130)의 중심축이 회전축(RY)에 직교하는 방향으로 회전축(RY)으로부터 이격되어 있다. 이에 따라, 제2 홀더(150)에 의해 실러샤프트(130)는 회전축(RY)과 소정 각도 경사진다. 또한, 실러샤프트의 노즐(133)이 회전축(RY)으로부터 편심량(EY)만큼 편심된다.That is, in the area of the second holder (150), the central axis of the sealer shaft (130) is spaced apart from the rotation axis (RY) in a direction orthogonal to the rotation axis (RY). Accordingly, the sealer shaft (130) is inclined at a predetermined angle with respect to the rotation axis (RY) by the second holder (150). In addition, the nozzle (133) of the sealer shaft is eccentric from the rotation axis (RY) by an eccentricity amount (EY).

제2 홀더(150)에 의해, 제2 홀더(150)와 접촉되는 실러샤프트(130)가 회전축(RY)으로부터 편심되게 기울지고, 노즐(133)이 편심량(EY)만큼 편심되어 있다.By the second holder (150), the sealer shaft (130) in contact with the second holder (150) is tilted eccentrically from the rotation axis (RY), and the nozzle (133) is eccentric by the eccentricity amount (EY).

로터샤프트(120)가 회전축(RY)을 중심로 회전되면, 제2 홀더(150)는 로터샤프트(120)의 회전축(RY)과 동축으로 회전된다. 제2 홀더(150)와 접촉하는 실러샤프트(130)가 회전축(RY)으로부터 편심되게 기울어 있다. 또한, 실러샤프트(130)의 상단부(일단)는 구(sphere) 또는 구체 또는 볼(ball) 형상의 제1 회동구(131)가 하우징(1100) 내부에 안착 수용되어 있다. 이에 따라, 제2 홀더(150)의 회전과 함께, 노즐(133)은 회전축(RY)을 중심으로 하여 원운동한다. 노즐(133)의 이러한 원운동에 있어서, 실러샤프트(130)는 회전축(RY)에 대하여 경사진 상태로, 원형의 궤적을 따라 이동된다. 노즐(133)의 원운동의 반경은, 상기 노즐의 편심량(EY)의 치수가 될 수 있다. 노즐(133)이 개방된 상태에서 노즐(133)이 회전축(RY)을 중심으로하여 원운동하므로, 제1 실시 예에 따른 스월 디스펜서 장치(100)는 실러(SL)를 스월 패턴(swerl pattern)으로 도포할 수 있다.When the rotor shaft (120) rotates around the rotation axis (RY), the second holder (150) rotates coaxially with the rotation axis (RY) of the rotor shaft (120). The sealer shaft (130) in contact with the second holder (150) is tilted eccentrically from the rotation axis (RY). In addition, the upper end (one end) of the sealer shaft (130) has a first rotary member (131) in the shape of a sphere or a ball, which is seated and accommodated inside the housing (1100). Accordingly, along with the rotation of the second holder (150), the nozzle (133) rotates circularly around the rotation axis (RY). In this circular movement of the nozzle (133), the sealer shaft (130) is moved along a circular trajectory while being tilted with respect to the rotation axis (RY). The radius of circular motion of the nozzle (133) may be the dimension of the eccentricity (EY) of the nozzle. Since the nozzle (133) rotates circularly around the rotation axis (RY) when the nozzle (133) is open, the swirl dispenser device (100) according to the first embodiment can apply the sealer (SL) in a swirl pattern.

제2 홀더(150)가 실러샤프트(130)의 자유단(타단)에 인접하므로, 실러샤프트(130)는 제1 회동구(131)로부터 제2 홀더(150)를 향하여 소정 각도 기울어질 수 있다. 즉, 제2 홀더(150)는, 제1 회동구(131)로부터 제2 홀더(150)를 향하여 실러샤프트(130)의 편심량(EY)이 커지도록, 실러샤프트(130)를 회전축(RY)에 대하여 경사지게 한다. 제2 홀더(150)가 회전함에 따라, 실러샤프트(130)는 회전축(RA)에 대하여 경사진 상태로, 원추 또는 원뿔의 궤적을 따라 이동될 수 있다.Since the second holder (150) is adjacent to the free end (other end) of the sealer shaft (130), the sealer shaft (130) can be inclined at a predetermined angle from the first rotary member (131) toward the second holder (150). That is, the second holder (150) inclines the sealer shaft (130) with respect to the rotation axis (RY) so that the eccentricity (EY) of the sealer shaft (130) increases from the first rotary member (131) toward the second holder (150). As the second holder (150) rotates, the sealer shaft (130) can move along the trajectory of a cone or cone while being inclined with respect to the rotation axis (RA).

따라서, 제2 홀더(150)는 도 3에 도시된 바와 같이, 회전축(RY)과 동축으로 로터샤프트(120) 하단에 고정되어 실러샤프트(130) 타측을 지지하고, 실러샤프트(130)를 회전축(RY)을 따라 경사지게 노즐(133)을 회전축(RY)으로부터 편심시킬 수 있다.Accordingly, as shown in FIG. 3, the second holder (150) is fixed to the lower end of the rotor shaft (120) coaxially with the rotation axis (RY) to support the other side of the sealer shaft (130), and the sealer shaft (130) can be inclined along the rotation axis (RY) to eccentrically move the nozzle (133) from the rotation axis (RY).

특히, 제2 홀더(150)는 실러샤프트(130) 타측의 외주면을 지지하되 회전축(RY)에 직교하는 방향으로 편심되어 있는 베어링(151)으로 결합될 수 있다.In particular, the second holder (150) can be combined with a bearing (151) that supports the outer surface of the other side of the sealer shaft (130) but is eccentric in a direction orthogonal to the rotation axis (RY).

또한, 제2 홀더(150)는 제1 회동구(131)로부터 제2 홀더(150)를 향하여 실러샤프트(130)의 편심량(EY)이 커지도록 실러샤프트(130)를 경사지게 하고, 베어링(151)은 회전축(RY)을 중심으로 하는 실러샤프트(130)의 원운동을 허용하도록 구성되며, 베어링(151)은 제1 회동구(131)를 중심으로 하는 실러샤프트(130)의 원추(원뿔)운동을 허용하도록 구성될 수 있다.In addition, the second holder (150) tilts the sealer shaft (130) so that the eccentricity (EY) of the sealer shaft (130) increases from the first rotary member (131) toward the second holder (150), and the bearing (151) is configured to allow circular motion of the sealer shaft (130) centered on the rotation axis (RY), and the bearing (151) can be configured to allow conical motion of the sealer shaft (130) centered on the first rotary member (131).

즉, 제2 홀더(150)는 실러샤프트(130)의 외주면과 결합되는 베어링(151)을 포함한다. 베어링(151)은 회전축(RY)에 직교하는 방향으로 편심되도록 배치된다. 베어링(151)의 편심량(EY)은 실러샤프트의 노즐(133)이 상기한 편심량(EY)을 갖도록 설정될 수 있다. 제2 홀더(150)의 회전축을 중심으로 하는 회전 시에, 실러샤프트(130)가 회전축(RY)을 중심으로 하는 원운동을 하므로, 베어링(151)은 이러한 실러샤프트(130)의 원운동을 허용하도록 구성된다. 로터샤프트(120)의 회전에 따라, 제2 홀더(150)에 의해 편심된 실러샤프트(130)는 원추 또는 원뿔 형상으로 회동한다.That is, the second holder (150) includes a bearing (151) coupled with the outer surface of the sealer shaft (130). The bearing (151) is arranged to be eccentric in a direction orthogonal to the rotation axis (RY). The eccentricity (EY) of the bearing (151) can be set so that the nozzle (133) of the sealer shaft has the above-described eccentricity (EY). When the second holder (150) rotates around its rotation axis, the sealer shaft (130) performs a circular motion around the rotation axis (RY), and therefore, the bearing (151) is configured to allow such circular motion of the sealer shaft (130). As the rotor shaft (120) rotates, the sealer shaft (130) eccentrically rotates in a cone or conical shape by the second holder (150).

실러개폐부(160)는 도 3의 (b)에 도시된 바와 같이, 실러샤프트(130) 내로 연통되게 형성된 실러유로(161)를 실러밸브(162)로 개폐할 수 있는 장치이다.The sealer opening/closing unit (160) is a device that can open/close a sealer passage (161) formed to be connected to the sealer shaft (130) by a sealer valve (162), as shown in (b) of FIG. 3.

실러개폐부(160)는 실러 도포시 실러밸브(162)가 실러유로(161)를 개방시켜 노즐(133)로 실러(SL)를 분출시키고, 실러 도포 중단시 실러샤프트(130) 내의 실러(SL)를 스닢(sniff, 코로 코물을 훔치듯이) 흡입하여 실러유로(161)를 폐쇄시켜 실러샤프트(130) 내의 압력이 대기압보다 낮아지므로, 주위보다 낮아지는 부압(negative pressure)이 발생하여 노즐(133)로부터 실러(SL)가 흘러내지 않게 방지할 수 있다.When applying the sealer, the sealer opening/closing part (160) opens the sealer passage (161) through the sealer valve (162) to spray the sealer (SL) through the nozzle (133), and when application of the sealer is stopped, the sealer (SL) inside the sealer shaft (130) is sucked in (like sniffing snot with the nose) to close the sealer passage (161), so that the pressure inside the sealer shaft (130) becomes lower than the atmospheric pressure, thereby generating a negative pressure lower than the surroundings, thereby preventing the sealer (SL) from flowing out from the nozzle (133).

더욱 구체적으로, 실러개폐부(160)는 도 3의 (b)에 도시된 바와 같이, 개방된 노즐(133)로 실러(SL)를 분출시키기 위하여 실러유로(161) 상에 있는 실러밸브(162)를 하강시키면, 막혀 있던 실러유로(161)가 열리면서 실러샤프트(130) 내에 분출 압력을 제공하여 상기 노즐(133)를 통하여 실러(SL)를 도포할 수 있다.More specifically, as shown in (b) of FIG. 3, the sealer opening/closing unit (160) lowers the sealer valve (162) on the sealer passage (161) to spray the sealer (SL) through the open nozzle (133), thereby opening the sealed sealer passage (161) and providing spray pressure within the sealer shaft (130) to apply the sealer (SL) through the nozzle (133).

또한, 실러개폐부(160)는 도 3의 (b)에 도시된 바와 같이, 개방된 노즐(133)로 실러(SL)의 분출을 중단시키기 위하여 실러유로(161) 상에 있는 실러밸브(162)를 상승시키면, 실러샤프트(130) 내에 있던 실러(SL)를 코로 코물을 훔치듯이 스닢(sniff) 흡입하여 열려 있던 실러유로(161)가 폐쇄되면서 실러샤프트(130) 내에 압력이 대기압보다 낮아지므로, 주위보다 낮아지는 부압(negative pressure)이 발생하여 노즐(133)로부터 실러(SL)가 흘러내지 않게 방지할 수 있다.In addition, as shown in (b) of FIG. 3, when the sealer opening/closing part (160) raises the sealer valve (162) on the sealer passage (161) to stop the spraying of the sealer (SL) through the open nozzle (133), the sealer (SL) in the sealer shaft (130) is sucked in like sniffing snot with a nose, and when the open sealer passage (161) is closed, the pressure inside the sealer shaft (130) becomes lower than the atmospheric pressure, so that a negative pressure lower than the surroundings is generated, which can prevent the sealer (SL) from flowing out from the nozzle (133).

특히, 종래의 기술은 도 1에 도시된 바와 같이, 실러 샤프트(1300) 내에 실러 샤프트(1300)보다 긴 길이의 니들 로드(1510)가 삽입되어 노즐(1330)을 개폐하므로, 실러 샤프트(1300) 내에 있는 실러가 실러 샤프트(1300) 및 니들 로드(1510)에 둘러쌓여 표면적이 넓어 쉽게 냉각되거나 가열되고, 상대적으로 단면적이 적어 미세한 압력 변동에도 실러 도포에 영향을 주는 등 매우 불리한 문제점을 안고 있는 구성이다.In particular, the conventional technology, as illustrated in FIG. 1, has a configuration in which a needle rod (1510) longer than the sealer shaft (1300) is inserted into the sealer shaft (1300) to open and close the nozzle (1330), so that the sealer within the sealer shaft (1300) is surrounded by the sealer shaft (1300) and the needle rod (1510) and thus has a large surface area, so that it is easily cooled or heated, and has a relatively small cross-sectional area, so that even a slight pressure fluctuation affects the sealer application, which is a very disadvantageous problem.

즉, 종래의 기술은 노즐(1330) 상측을 바늘과 같이 좁고 긴 니들 로드(1510)가 승강하여 개폐하는데, 미세한 압력에도 쉽게 막히기도 하고, 실러 도포 중 끊어짐이 자주 발생하거나, 쉽게 냉각되어 실러가 굳어질 수 있다.That is, in the conventional technology, a narrow and long needle rod (1510) like a needle is raised and lowered on the upper side of the nozzle (1330) to open and close, but it can easily become clogged even under a slight pressure, frequently break during sealer application, or easily cool down and cause the sealer to harden.

하지만, 본 발명이 제안하는 실러개폐부(160)는 실러샤프트(130) 내의 공간에 충진된 실러(SL)가 완충 작용을 하여 온도 변화에 쉽게 영향을 받지 않으면서 이격되어 있는 실러밸브(162)를 제어하므로 오픈된 노즐(133)을 효과적으로 단속할 수 있다.However, the sealer opening/closing unit (160) proposed by the present invention can effectively control the open nozzle (133) by controlling the sealer valve (162) that is spaced apart without being easily affected by temperature changes by the sealer (SL) filled in the space within the sealer shaft (130) acting as a buffer.

본 발명의 제2 실시 예에 따른 스월 디스펜서 장치(200)는 도 4 및 도 5에 도시된 바와 같이, 스월(swerl) 형태로 실러(sealer or sealant)를 도포하는 장치로, 하우징(210)과, 로터샤프트(220)와, 실러샤프트(230)와, 제1 홀더(240), 및 제2 홀더(250) 등을 포함한다.A swirl dispenser device (200) according to a second embodiment of the present invention is a device for applying a sealer (sealer or sealant) in a swirl form, as shown in FIGS. 4 and 5, and includes a housing (210), a rotor shaft (220), a sealer shaft (230), a first holder (240), a second holder (250), etc.

하우징(210)은 앞에서 언급한 하우징(110)을 참고하여 적용된다. 하우징(210)은 내부에 고정자(211)를 갖는다. 고정자(211)는 하우징(210)에 부착된 전원커넥터(미도시)를 통해 전원으로부터 전력을 공급받는다. 한편, 하우징(210)은 조립하거나 해체하여 보수하기 용이하게 복수의 블럭(block)으로 구성될 수 있고, 상호 수밀 또는 기밀하게 결합될 수 있다.The housing (210) is applied with reference to the housing (110) mentioned above. The housing (210) has a stator (211) inside. The stator (211) receives power from a power source through a power connector (not shown) attached to the housing (210). Meanwhile, the housing (210) may be composed of a plurality of blocks for easy maintenance by assembling or disassembling, and may be watertightly or airtightly coupled to each other.

로터샤프트(220)는 앞에서 언급한 로터샤프트(120)를 참고하여 적용된다. 도 4에 도시된 바와 같이, 고정자(211)와 상호 작용하는 회전자(221)를 갖고 하우징(210)의 내부에 회전축(RY)을 중심으로 회전되도록 결합되는 샤프트(shaft)부재이다. 이때, 로터샤프트(220)는 하우징(210) 내에서 베어링에 의해서 지지되어 회동할 수 있다. 또한, 상기 베어링은 로터샤프트(220)의 외주면에 결합되어 로터샤프트(220)를 회전축(RY)을 중심으로 회전 가능하게 지지할 수 있다.The rotor shaft (220) is applied with reference to the rotor shaft (120) mentioned above. As illustrated in FIG. 4, it is a shaft member that has a rotor (221) that interacts with a stator (211) and is coupled to the inside of the housing (210) so as to rotate around the rotation axis (RY). At this time, the rotor shaft (220) can be supported and rotated by a bearing within the housing (210). In addition, the bearing can be coupled to the outer circumferential surface of the rotor shaft (220) to support the rotor shaft (220) so as to rotate around the rotation axis (RY).

한편, 본 발명에서는 회동이 원활하도록 다수의 베어링을 사용하고 있으나, 상기 베어링 중 특징적인 기능이 있는 것에 대해서만 부호를 부여하여 자세히 설명하고 나머지는 부호를 부여하지 않고 간단히 설명한다.Meanwhile, in the present invention, a number of bearings are used to ensure smooth rotation, but only bearings with characteristic functions among the bearings are described in detail by assigning symbols, and the rest are described simply without assigning symbols.

실러샤프트(230)는 앞에서 언급한 실러샤프트(130) 일부를 참고하여 적용된다. 도 4에 도시된 바와 같이, 실러(SL)가 유입되고 하우징(210)의 내부로 삽입되는 일단에 고정된 구체 또는 볼(ball) 형상의 제1 회동구(231)와 실러(SL)를 분출하는 노즐(233)이 타단에 형성되고 회전축(RY)을 따라 로터샤프트(220)를 관통하도록 형성된 중공의 샤프트(shaft)부재이다.The sealer shaft (230) is applied with reference to a part of the sealer shaft (130) mentioned above. As illustrated in Fig. 4, it is a hollow shaft member having a first rotary port (231) in the shape of a sphere or ball fixed at one end through which the sealer (SL) is introduced and inserted into the interior of the housing (210), and a nozzle (233) for spraying the sealer (SL) formed at the other end, and formed to penetrate the rotor shaft (220) along the rotation axis (RY).

실러샤프트(230)는 실러유로(261)로부터 공급된 실러(SL)를 수용하고, 도포 작업 시에 실러(SL)를 분출한다. 실러샤프트(230)는 로터샤프트(220)의 회전축(RY)을 따르는 길이보다 긴 길이를 가진다. 실러샤프트(230)는 회전축(RY)을 따라 로터샤프트(220)를 관통하도록 형성되고, 실러샤프트(230)가 로터샤프트(220)의 내부에 배치된다.The sealer shaft (230) receives the sealer (SL) supplied from the sealer oil (261) and sprays the sealer (SL) during the application process. The sealer shaft (230) has a length longer than the length along the rotation axis (RY) of the rotor shaft (220). The sealer shaft (230) is formed to penetrate the rotor shaft (220) along the rotation axis (RY), and the sealer shaft (230) is arranged inside the rotor shaft (220).

실러샤프트(230)는 하우징(210) 내에 타단이 자유단이 되는 내민보(Single overhanging beam)의 형태로, 상하 높이(승강) 방향으로 배치된다. 즉, 실러샤프트(230)는 일단에 회동볼(ball)처럼 3차원 회동이 가능하도록 구체 또는 볼(ball) 형상의 제1 회동구(231)가 장착되고, 타단에 가까운 타측으로 3차원 회동이 가능하도록 구체 또는 타원체 형상의 제2 회동구(232)가 형성된다.The sealer shaft (230) is arranged in the vertical height (lifting) direction in the form of a single overhanging beam with the other end being free within the housing (210). That is, the sealer shaft (230) is equipped with a first rotary member (231) in the shape of a sphere or ball to enable three-dimensional rotation like a rotary ball at one end, and a second rotary member (232) in the shape of a sphere or ellipsoid is formed to enable three-dimensional rotation on the other end closer to the other end.

특히, 본 발명이 제안하는 실러샤프트(230)는 도 4의 (a)에 도시된 바와 같이, 구체 또는 볼(ball) 형상의 제1 회동구(231)가 하우징(210)의 내부에 수용되어 휘지 않고 3차원 점(ball)회동이 가능하여, 종래의 문제점을 해결하면서 도 2와 같이 실러(SL)를 연속적이고 균일하게 일정한 간격으로 도포할 수 있다.In particular, the sealer shaft (230) proposed by the present invention, as shown in (a) of FIG. 4, has a first rotary member (231) in the shape of a sphere or ball accommodated inside the housing (210) so as to be capable of three-dimensional point (ball) rotation without bending, thereby solving the problems of the prior art and enabling continuous and uniform application of the sealer (SL) at regular intervals as shown in FIG. 2.

더욱 구체적으로, 제1 회동구(231)는 외주면이 구체(sphere) 또는 볼(ball) 형상으로, 제1 홀더(240)에 수용된 상태에서 조이스틱처럼 자유롭게 3차원 틸팅 회동이 가능하여 종래에 실러 샤프트 일단이 고정되어 휘어져 실러 도포가 균일하지 못한 문제점을 해결할 수 있다.More specifically, the first rotary shaft (231) has an outer surface in the shape of a sphere or ball, and can freely rotate in three dimensions tilting like a joystick while being accommodated in the first holder (240), thereby solving the problem of uneven sealer application due to one end of the sealer shaft being fixed and bent in the past.

더 나아가, 실러샤프트(230)가 상대적으로 길이가 짧아지더라도 비틀림이나 휘어짐 등이 발생하지 않도록, 제2 회동구(232)는 외주면이 구체(sphere) 또는 타원체 형상으로, 제2 홀더(250)에 수용된 상태에서 조이스틱처럼 자유롭게 3차원 틸팅 회동이 가능하여 제1 실시 예의 실러샤프트(130)를 보완할 수 있다.Furthermore, in order to prevent twisting or bending, etc. from occurring even when the sealer shaft (230) is relatively shortened, the second rotary member (232) has an outer surface in the shape of a sphere or ellipsoid, and can freely rotate in three dimensions tilting like a joystick while being accommodated in the second holder (250), thereby complementing the sealer shaft (130) of the first embodiment.

실러샤프트(230)는 타단에 자유단을 가지되 실러(SL)를 분출하는 노즐(233)이 형성되고, 중공의 내부 빈 공간에 실러(SL)가 충진되어 내부압에 따라 오픈된 노즐(233)을 통하여 상기 실러(SL)가 분출될 수 있게 한다.The sealer shaft (230) has a free end at the other end and a nozzle (233) for spraying a sealer (SL) is formed, and the sealer (SL) is filled in the hollow internal space so that the sealer (SL) can be sprayed through the nozzle (233) that is opened according to the internal pressure.

이때, 실러샤프트(230)의 자유단에 형성된 노즐(233)은 회전축(RY)으로부터 편심되어 있다. 이에 따라, 로터샤프트(220)가 회전하면, 노즐(233)은 로터샤프트(220)의 회전축(RY)을 중심으로 하여 원운동을 실행한다. 로터샤프트(220)와 실러샤프트(230) 타측에 배치되는 제2 홀더(250)가 노즐(233)을 편심시킨다.At this time, the nozzle (233) formed at the free end of the sealer shaft (230) is eccentric from the rotation axis (RY). Accordingly, when the rotor shaft (220) rotates, the nozzle (233) performs a circular motion centered on the rotation axis (RY) of the rotor shaft (220). The second holder (250) arranged on the other side of the rotor shaft (220) and the sealer shaft (230) eccentricizes the nozzle (233).

제1 홀더(240)는 실러샤프트(230) 일단을 잡아주는 부재로, 도 4의 (a)에 도시된 바와 같이, 회전축(RY)과 동축으로 하우징(210)의 내부 일측에 안착되어 제1 회동구(231)를 수용하는 지지공간을 제공할 수 있다.The first holder (240) is a member that holds one end of the sealer shaft (230), and as shown in (a) of FIG. 4, can be installed on one side of the inside of the housing (210) coaxially with the rotation axis (RY) to provide a support space for accommodating the first rotary member (231).

특히, 제1 홀더(240)는 제1 회동구(231)가 3차원 틸팅 회동이 가능하도록 지지하는데, 상기 제1 회동구(231)를 요입(凹入) 형상으로 수용하여 지지하되 상기 제1 회동구(231)가 틸팅(tilting) 회동 가능하게 결합될 수 있다.In particular, the first holder (240) supports the first rotary member (231) so that it can rotate in a three-dimensional tilting manner. The first rotary member (231) is supported by receiving it in a concave shape, and the first rotary member (231) can be coupled so that it can rotate in a tilting manner.

또한, 제1 홀더(240)는 도 4의 (a)에 도시된 바와 같이, 양팔을 벌리듯 한쌍의 유도부재(241)가 제1 회동구(231) 외주면을 소정 높이로 감싸되, 상기 한쌍의 유도부재(241) 사이로 단면이 "ㅓ"자 형상의 링부재(242)가 상기 제1 회동구(231) 외측방을 지지하여 상기 제1 회동구(231)와 접촉을 최소화하여 회동 저항(마찰)이 적어지므로, 수용된 공간에서 자유롭게 3차원 회동이 가능하게 한다.In addition, as shown in (a) of FIG. 4, the first holder (240) has a pair of inductive members (241) that wrap around the outer surface of the first rotary member (231) at a predetermined height, as if spreading out two arms, and a ring member (242) having a cross-section in the shape of the letter "ㅓ" between the pair of inductive members (241) supports the outer side of the first rotary member (231), minimizing contact with the first rotary member (231) and reducing rotational resistance (friction), thereby enabling free three-dimensional rotation in the accommodated space.

또한, 제1 홀더(240)는 유도부재(241) 및 링부재(242)를 수용하는 홀더하우징(243)에 의해 모듈화될 수 있고, 유도부재(241), 링부재(242), 및 홀더하우징(243)이 일체로 움직일 수 있다.In addition, the first holder (240) can be modularized by a holder housing (243) that accommodates a guide member (241) and a ring member (242), and the guide member (241), the ring member (242), and the holder housing (243) can move as one unit.

제2 홀더(250)는 도 5의 (a)에 도시된 바와 같이, 로터샤프트(220)의 하단부(타단)에 고정 및 결합되고, 로터샤프트(220)에 회전축(RY)과 동축으로 회전하도록 고정된다.The second holder (250) is fixed and coupled to the lower end (other end) of the rotor shaft (220), as shown in (a) of FIG. 5, and is fixed to rotate coaxially with the rotation axis (RY) of the rotor shaft (220).

제2 홀더(250)는 로터샤프트(220)의 하단부의 외주면과 결합되는 링(ring) 형상으로, 실러샤프트(230)를 지지한다. 제2 홀더(250)는 실러샤프트(230)를 회전축(RY)에 직교하는 방향으로 소정의 편심량(EY)만큼 편심시키도록 구성된다.The second holder (250) has a ring shape that is combined with the outer surface of the lower end of the rotor shaft (220) and supports the sealer shaft (230). The second holder (250) is configured to eccentrically move the sealer shaft (230) by a predetermined amount of eccentricity (EY) in a direction perpendicular to the rotation axis (RY).

특히, 제2 홀더(250)는 제2 회동구(232)가 3차원 틸팅 회동이 가능하도록 지지하는데, 상기 제2 회동구(232)를 요입(凹入) 형상으로 수용하여 지지하되 상기 제2 회동구(232)가 틸팅(tilting) 회동 가능하게 결합되어 제1 홀더(240)와 연동하여 실러샤프트(230)가 틀어지거나 변형되지 않게 유동성을 제공한다.In particular, the second holder (250) supports the second rotary member (232) so that it can rotate in three dimensions by tilting. The second rotary member (232) is supported by receiving it in a concave shape, but the second rotary member (232) is coupled so that it can rotate by tilting, and in conjunction with the first holder (240), provides flexibility so that the sealer shaft (230) is not twisted or deformed.

실러샤프트(230)의 상단부(일단)는 구체(sphere) 또는 볼(ball) 형상의 제1 회동구(231)가 하우징(210) 내부에 안착 수용되어 있다. 이에 따라, 제2 홀더(250)의 회전과 함께, 노즐(233)은 회전축(RY)을 중심으로 하여 원운동한다. 노즐(233)의 이러한 원운동에 있어서, 실러샤프트(230)는 회전축(RY)에 대하여 경사진 상태로, 원형의 궤적을 따라 이동된다.The upper end (one end) of the sealer shaft (230) has a first rotary member (231) in the shape of a sphere or ball, which is accommodated within the housing (210). Accordingly, along with the rotation of the second holder (250), the nozzle (233) rotates circularly around the rotation axis (RY). In this circular movement of the nozzle (233), the sealer shaft (230) moves along a circular trajectory while being inclined with respect to the rotation axis (RY).

노즐(233)이 개방된 상태에서, 노즐(233)이 회전축(RY)을 중심으로 하여 원운동하므로, 제2 실시 예에 따른 스월 디스펜서 장치(200)는 실러(SL)를 스월 패턴(swerl pattern)으로 도포할 수 있다.When the nozzle (233) is open, the nozzle (233) rotates circularly around the rotation axis (RY), so the swirl dispenser device (200) according to the second embodiment can apply the sealer (SL) in a swirl pattern.

따라서, 제2 홀더(250)는 도 4 및 도 5에 도시된 바와 같이, 회전축(RY)과 동축으로 로터샤프트(220) 하단에 고정되어 실러샤프트(230) 타측을 지지하고, 실러샤프트(230)를 회전축(RY)을 따라 경사지게 노즐(233)을 회전축(RY)으로부터 편심시킬 수 있다.Accordingly, the second holder (250) is fixed to the lower end of the rotor shaft (220) coaxially with the rotation axis (RY), as shown in FIGS. 4 and 5, to support the other side of the sealer shaft (230), and the sealer shaft (230) can be inclined along the rotation axis (RY) to eccentrically move the nozzle (233) from the rotation axis (RY).

특히, 제2 홀더(250)는 실러샤프트(230) 타측의 제2 회동구(232) 외주면을 지지하되 회전축(RY)에 직교하는 방향으로 편심되어 있는 베어링(251)이 제2 홀더(250)의 내부 상하 승강방향으로 슬라이딩되게 결합될 수 있고, 실러샤프트(230)의 승강방향을 따라 상기 베어링(251)이 제2 홀더(250) 내에서 슬라이딩(sliding)될 수 있다.In particular, the second holder (250) supports the outer surface of the second rotary member (232) on the other side of the sealer shaft (230), and a bearing (251) that is eccentric in a direction orthogonal to the rotation axis (RY) can be coupled to slide in the internal up-and-down direction of the second holder (250), and the bearing (251) can slide within the second holder (250) along the up-and-down direction of the sealer shaft (230).

또한, 베어링(251)은 복식 베어링으로, 도 5의 (a)에 도시된 바와 같이, 내주면에 요입홈(252)이 형성되어 상기 제2 회동구(232)를 감싸 수용하여 높이방향 상하측에서 구름운동할 수 있다.In addition, the bearing (251) is a double bearing, and as shown in (a) of FIG. 5, a groove (252) is formed on the inner surface to surround and accommodate the second rotary member (232) and enable rolling movement in the vertical direction.

즉, 제2 홀더(250)의 회전축을 중심으로 하는 회전 시에, 로터샤프트(220)의 회전에 따라, 제2 홀더(250)에 의해 편심된 실러샤프트(230)는 원추 또는 원뿔 형상으로 회동한다.That is, when rotating around the rotation axis of the second holder (250), the sealer shaft (230) eccentrically rotated by the second holder (250) in a cone or conical shape according to the rotation of the rotor shaft (220).

실러개폐부(260)는 앞에서 언급한 실러개폐부(160)를 참고하여 적용된다. 도 4의 (b)에 도시된 바와 같이, 실러샤프트(230) 내로 연통되게 형성된 실러유로(261)를 실러밸브(262)로 개폐할 수 있는 장치이다.The sealer opening/closing unit (260) is applied with reference to the sealer opening/closing unit (160) mentioned above. As shown in (b) of Fig. 4, it is a device that can open/close a sealer passage (261) formed to be connected to the sealer shaft (230) by a sealer valve (262).

실러개폐부(260)는 실러 도포시 실러밸브(262)가 실러유로(261)를 개방시켜 노즐(233)로 실러(SL)를 분출시키고, 실러 도포 중단시 실러샤프트(230) 내의 실러(SL)를 스닢(sniff, 코로 코물을 훔치듯이) 흡입하여 실러유로(261)를 폐쇄시켜 실러샤프트(230) 내의 압력이 대기압보다 낮아지므로, 주위보다 낮아지는 부압(negative pressure)이 발생하여 노즐(233)로부터 실러(SL)가 흘러내지 않게 방지할 수 있다.When applying the sealer, the sealer opening/closing part (260) opens the sealer passage (261) through the sealer valve (262) to spray the sealer (SL) through the nozzle (233), and when application of the sealer is stopped, the sealer (SL) inside the sealer shaft (230) is sucked in (like sniffing snot with the nose) to close the sealer passage (261), so that the pressure inside the sealer shaft (230) becomes lower than the atmospheric pressure, thereby generating a negative pressure lower than the surroundings, thereby preventing the sealer (SL) from flowing out from the nozzle (233).

본 발명이 제안하는 실러개폐부(260)는 실러샤프트(230) 내의 공간에 충진된 실러(SL)가 완충 작용을 하여 온도 변화에 쉽게 영향을 받지 않으면서 이격되어 있는 실러밸브(262)를 제어하므로 오픈된 노즐(233)을 효과적으로 단속할 수 있다.The sealer opening/closing unit (260) proposed by the present invention can effectively control the sealer valve (262) that is spaced apart without being easily affected by temperature changes by the sealer (SL) filled in the space within the sealer shaft (230) acting as a buffer, so that the open nozzle (233) can be effectively blocked.

신축부(270)는 도 5의 (b)에 도시된 바와 같이, 노즐(233)의 높이를 승강시키는 장치로, 구배가 형성된 패널 표면을 따라 로봇암 등에 의하지 않고 직접적으로 제어될 수 있게 한다.The expansion member (270) is a device that raises and lowers the height of the nozzle (233), as shown in (b) of Fig. 5, and can be directly controlled along the panel surface on which a gradient is formed without using a robot arm or the like.

즉, 신축부(270)는 하우징(210)에 연장 설치되어 작동유나 공기 등과 같은 유체(流體)를 제1 유로(171) 및 제2 유로(172)에 공급하므로, 제1 홀더(240)를 승강시킬 수 있다. 이때, 제1 홀더(240)는 제1 회동구(231)를 회동 가능하게 홀딩(holding)하면서 신축부(270) 내에서 상하로 승강될 수 있다.That is, the expansion member (270) is installed as an extension to the housing (210) and supplies a fluid such as operating oil or air to the first flow path (171) and the second flow path (172), so that the first holder (240) can be raised and lowered. At this time, the first holder (240) can be raised and lowered up and down within the expansion member (270) while rotatably holding the first rotary member (231).

여기서, 유체가 제1 유로(171)으로 유입되어 제2 유로(172)로 배출되면 제1 홀더(240)가 상승하게 되고, 유체가 제2 유로(172)으로 유입되어 제1 유로(171)로 배출되면 제1 홀더(240)가 하강하게 된다.Here, when the fluid flows into the first flow path (171) and is discharged into the second flow path (172), the first holder (240) rises, and when the fluid flows into the second flow path (172) and is discharged into the first flow path (171), the first holder (240) descends.

따라서, 신축부(270)는 제1 회동구(231)를 회동 가능하게 물고 있는 제1 홀더(240)를 승강시켜 노즐(233)이 형성된 상기 실러샤프트(230) 타측을 비례하여 승강시켜 상기 노즐(233)의 높이를 조절할 수 있고, 실러 도포 대상인 패널 상에 설정된 높이로 운영될 수 있게 한다. 이때, 신축부(270)는 하우징(210) 내부에서 수밀 또는 기밀되어 제1 홀더(240)를 승강시킬 수 있다.Accordingly, the expansion member (270) elevates the first holder (240) that rotatably holds the first rotary member (231) and proportionally elevates the other side of the sealer shaft (230) on which the nozzle (233) is formed, thereby adjusting the height of the nozzle (233), and enables it to be operated at a set height on the panel to which the sealer is applied. At this time, the expansion member (270) can elevate the first holder (240) by being watertight or airtight inside the housing (210).
