Description

컨베이어 보드{conveyor board}Conveyor board

본 발명은 컨베이어 보드에 관한 것으로서, 더욱 상세하게는 합판, 목재, MDF, 금속, 화장판 및 발포수지 등을 심재로 사용하고 상기 심재의 외부에 폴리우레탄을 코팅하여 폴리우레탄층으로 형성한 컨베이어 보드로써, 상기 심재와 폴리우레탄층 사이에는 시멘트가 포함된 결합강화제를 도포함으로써 접착력의 향상과 함께 강도를 향상시킨 컨베이어 보드이다.
The present invention relates to a conveyor board, and more particularly, to a conveyor board using a plywood, a wood, an MDF, a metal, a veneer and a foamed resin as a core material and coating the outer surface of the core with polyurethane, And a bonding enhancer containing cement is applied between the core and the polyurethane layer to improve the adhesive strength and the strength of the conveyor board.

일반적으로 컨베이어 보드(conveyor board)는 파렛트(팰릿, pallet) 또는 줄여서 보드(board)라고도 하며, 제품(부품)이 놓인 상태에서 컨베이어를 따라 이송되면서 조립이나 검사가 이루어지는데, 이러한 컨베이어 보드는 위에 놓이는 제품의 무게에 따라 적정한 강도가 유지되어야만 제품의 처짐이 방지되며, 적정한 내열성이 유지되어야만 상온보다 비교적 높은 고온에서 작업이 이루어지는 전자제품 컨베이어에서도 그 수명이 유지된다.
In general, a conveyor board is also referred to as a pallet or a board, and is assembled and inspected while a product (part) is being conveyed along a conveyor. According to the weight of the product, it is necessary to maintain the proper strength to prevent sagging of the product. If the heat resistance is maintained, the lifetime of the electronic conveyor can be maintained even at a relatively high temperature.

이러한 컨베이어 보드는 컨베이어를 따라 설치되어 있는 각 단계별 라인을 순차적으로 거치면서 작업이 이루어지게 되는데, 컨베이어 라인에서의 미끄러짐 방지와 분진발생방지 등을 위한 목적으로 심재의 외부에 (폴리)우레탄을 이용해 코팅을 해준 제품이 있는데, 이런 우레탄이 코팅된 종래의 컨베이어 보드로서는 본 출원인이 선출원하여 등록한 실용신안등록 제0267236호에 개시되어 있으며 도 3에 도시되어 있다.
These conveyor boards are processed by sequentially passing through each step of the line installed along the conveyor. In order to prevent slippage in the conveyor line and to prevent the generation of dust, the outer surface of the core is coated with (poly) urethane A conventional conveyor board coated with such urethane is disclosed in a utility model registration No. 0267236 filed by the present applicant and shown in FIG.

도 3에 도시되어 있는 자동화 라인용 컨베이어 보드(1)는 합판(2)에 코팅제(3)를 피복 형성하여 이루어지되, 합판(2)을 금형 내에 인서트시켜 액상의 우레탄(코팅제)을 금형에 인젝션하는 방식으로 성형하게 된다. 이로써 분진발생을 일소하고, 컨베이어 보드의 내마모성을 향상시킴과 동시에 코팅제(3)에 의해 합판(3)을 외기와 단절시키고 보강하여 제품의 변형과 처짐 현상 등을 사전 방지하여 평탄도를 높일 수 있는 장점이 있으나, 일정시간 사용 후에는 합판(2)과 코팅제(3)의 접착력이 떨어져 코팅제가 박리 되므로 코팅제(3)를 벗겨내고 재코팅을 해야 함으로써 유지보수비용이 증가되고 수명이 짧아지게 된다.
The conveyor board 1 for an automation line shown in Fig. 3 is formed by coating a plywood 2 with a coating agent 3, and inserting the plywood 2 into a metal mold to inject a liquid urethane (coating agent) . As a result, it is possible to improve the abrasion resistance of the conveyor board and to improve the flatness by preventing the deformation and sagging of the product by preventing the plywood (3) However, since the adhesive strength between the plywood (2) and the coating agent (3) deteriorates after a certain period of use, the coating agent is peeled off, so that the coating agent (3) needs to be peeled off and re-coated to increase the maintenance cost and shorten the service life.

또 다른 종래기술로서는 공개특허 제10-1999-0030962호에 개시되어 있는 컨베이어용 팔레트의 베이스판 제조방법이 있으며, 상기 공개특허에는 음극선관의 제조 공정 중에서 그 구성품들이 안치된 상태로 운반되도록 하는 컨베이어용 팔레트의 베이스판에 있어서, 금형의 내부에 나무로 제작된 판재를 설치하고 80℃ 이상으로 가열하는 단계와, 상기 금형에 액체 상태의 열경화성 수지와 경화제를 섞어 주입하는 단계와, 상기 금형을 30분 이상 방치하고, 이후 탈형하는 단계를 포함하여 이루어짐을 특징으로 하는 컨베이어용 팔레트의 베이스판 제조방법이 개시되어 있다.
Another conventional technique is a method of manufacturing a base plate of a pallet for a conveyor disclosed in Japanese Laid-Open Patent Publication No. 10-1999-0030962, which discloses a conveyor for conveying the components in an assembled state during the manufacturing process of a cathode ray tube A method of manufacturing a base pallet for a pallet, comprising the steps of: providing a plate made of wood in a mold and heating the plate to 80 DEG C or higher; injecting a mixture of a liquid thermosetting resin and a curing agent into the mold; Min, and thereafter demolding the pallet for a conveyor. The method for manufacturing a base plate of a pallet for a conveyor is disclosed.

상기 종래기술에 개시되어 있는 팔레트 역시 일정시간 사용 후에는 판재와 열경화성 수지(8)와의 접착력이 떨어져 수지가 박리 되므로 수지를 벗겨내고 재코팅을 해야 함으로써 유지보수비용이 증가되고 수명이 짧아지게 된다.
The pallet disclosed in the above-mentioned prior art also has an adhesive force between the plate material and the thermosetting resin 8 after a certain period of use, and the resin is peeled off. Thus, the resin needs to be peeled off and re-coated to increase the maintenance cost and shorten the service life.

이하, 첨부된 도면에 의해 본 발명의 바람직한 실시예를 상세히 설명하면 다음과 같다.
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 구성예시도이고, 도 2는 도 1의 A-A섹션 단면도로서, 본 발명에 의한 컨베이어 보드는 심재(20)의 외부에 폴리우레탄을 코팅하여 폴리우레탄층(40)으로 형성한 컨베이어 보드(10)에 있어서, 상기 심재(20)와 폴리우레탄층(40) 사이에는 심재(20)와 폴리우레탄층(40)과의 결합력을 높이기 위해 시멘트가 포함된 결합강화제(30)가 도포된 것이 특징이다.
1 is a cross-sectional view taken along the line AA of FIG. 1, and FIG. 2 is a cross-sectional view taken along the line AA of FIG. 1. In the conveyor board according to the present invention, polyurethane is coated on the outside of the core 20 to form a polyurethane layer 40 A bonding agent 30 containing cement is applied between the core material 20 and the polyurethane layer 40 in order to increase the bonding force between the core material 20 and the polyurethane layer 40 in the conveyor board 10, .

먼저, 심재(20)는 합판, 고압적층판, 강화우드, 글라스 화이바 및 화장판(化粧板) 중 어느 하나를 사용하거나 이들을 서로 접합한 복합소재를 사용할 수 있으며, 상기 심재(20)의 외부에는 폴리우레탄에 의해 폴리우레탄층(40)이 형성된다. 상기 폴리우레탄층(40)은 심재(20)의 외부에 시멘트가 포함된 결합강화제(30)를 도포한 뒤 코팅함으로써 형성되는데 금형 내에 결합강화제(30)가 도포된 심재(20)를 넣고 폴리우레탄 수지를 주입하는 인서팅 방식에 의해 형성할 수도 있고, 경우에 따라 결합강화제(30)가 도포된 심재(20) 외부에 폴리우레탄 수지를 일정두께로 분사하여 도포하는 방식이나 우레탄 수지를 직접 칠하는 방식으로도 형성할 수도 있다.
The core material 20 may be formed of a composite material obtained by using any one of a plywood, a high-pressure laminate, a reinforced wood, a glass fiber and a decorative laminate. The polyurethane layer 40 is formed by urethane. The polyurethane layer 40 is formed by applying a bonding agent 30 containing cement to the outside of the core material 20 and coating the core material 20. The core material 20 coated with the bonding agent 30 is placed in the mold, A method in which a polyurethane resin is sprayed to a certain thickness on the outside of the core material 20 on which the bonding agent 30 is applied and is applied, or a method in which a urethane resin is directly applied May also be formed.

상기 결합강화제(30)는 고형의 시멘트에 액상의 용매를 혼합하여 도포하는 것이 바람직한데, 이때 사용될 수 있는 용매로서는 자일렌(xylene)을 사용할 수 있다. 상기 자일렌은 벤젠고리에 메틸기(-CH3) 2개가 결합해 있는 구조의 방향족탄화수소로서, 색깔이 없고 투명한 액체로서 시너와 비슷한 냄새가 나는 액체인데, 휘발성이 높고 불에 잘 붙는 특성이 있다. 이러한 자일렌은 기초 화학물질을 만들 때 원료로 사용되며, 합성수지나 합성섬유 등의 원료로도 사용된다. 또한, 유성 도료, 인쇄용 잉크, 시너 및 잉크의 용매로 주로 사용된다.
It is preferable that the bonding enhancer 30 is applied by mixing a liquid solvent with solid cement. As the solvent that can be used at this time, xylene can be used. The xylene is an aromatic hydrocarbon having a structure in which two methyl groups (-CH 3 ) are bonded to the benzene ring. The liquid is a colorless and transparent liquid, and has a characteristic odor similar to that of a thinner. These xylenes are used as raw materials in the production of basic chemicals and also as raw materials for synthetic resins and synthetic fibers. They are also mainly used as solvents for oil-based paints, printing inks, thinner and inks.

본 발명은 이러한 자일렌을 용매로 사용하여 고상의 시멘트를 겔(gel) 상태로 만든 뒤 이를 도포함으로써 심재(20)에 균일한 두께의 도포가 가능하다.
In the present invention, it is possible to apply a uniform thickness of the core material 20 to the core material 20 by applying the solid state cement to the gel state using the xylene as a solvent.

상기 시멘트는 포틀랜드 시멘트를 사용할 수 있으며 상기 포틀랜드 시멘트는 그 주성분이 규산이칼슘, 규산삼칼슘인데 규산이칼슘은 화학식이 2CaOㆍSiO2로써 규산이석회라고 하며, 규산삼칼슘은 화학식이 3CaOㆍSiO2로써 규산삼석회라고 한다.

상기 결합강화제(30)는 시멘트, 자일렌 이외에 유기질 프리폴리머를 더 포함시킬 수 있다. The bonding enhancer 30 may further include an organic prepolymer in addition to cement and xylene.

일반적으로 프리폴리머는 성형하기 쉽게 하기 위하여 중합반응을 중도 단계에서 중지시킨 비교적 중합도(重合度)가 낮은 중합체(重合體)를 말하는 것으로 시멘트와 자일렌에 프로폴리머를 섞게 되면 결합강화제층의 성형이 용이하며 보다 고강성을 유지할 수 있다.
Generally, a prepolymer refers to a polymer having a relatively low degree of polymerization (polymerization degree) in which the polymerization reaction is stopped in the middle stage so as to facilitate molding. When a propylene polymer is mixed with cement and xylene, And it is possible to maintain higher rigidity.

상기 결합강화제는 시멘트, 자일렌, 프리폴리머 이외에 카보네이트(탄산염, carbonate)를 더 포함할 수 있다.
The binding enhancer may further include carbonate (carbonate) in addition to cement, xylene, and prepolymer.

카보네이트(carbonate)는 탄산 H2CO3의 수소가 금속으로 치환된 염으로, 이산화탄소 CO2와 금속산화물 또는 수산화물로 구성되는 염이다.
Carbonate is a salt in which hydrogen of carbonic acid H 2 CO 3 is substituted with a metal, and is a salt composed of carbon dioxide CO 2 and a metal oxide or hydroxide.

이하, 결합강화제(30)의 성분별 함유량을 살펴보면 다음과 같다.
Hereinafter, the content of each component of the bonding enhancer 30 will be described.

결합강화제(30)를 시멘트와 자일렌이 혼합된 것을 사용할 경우에는 시멘트의 함유량은 60~90 중량%, 자일렌은 10~40 중량%로 한다.When a mixture of the cement and xylene is used as the bonding enhancer 30, the content of cement is 60 to 90% by weight, and the content of xylene is 10 to 40% by weight.

시멘트의 함유량이 60 중량% 이하기 되면 점성이 낮아지고 강도가 저하되며, 반대로 90 중량% 이상이 되면 유동성이 떨어져 심재(20)에 도포할 때 도포가 어려우며 일정한 두께로 도포 되기도 어려우므로 상술한 비율을 유지하는 것이 바람직하다.
When the content of cement is less than 60% by weight, the viscosity decreases and the strength decreases. On the contrary, when the content of cement is more than 90% by weight, the fluidity deteriorates and it is difficult to apply the coating to the core material 20, .

결합강화제(30)를 시멘트와 자일렌 및 프리폴리머가 혼합된 것을 사용할 경우에는 시멘트 45~60 중량%, 자일렌 20~30 중량%, 프리폴리머 15~25 중량%로 한다.When the bonding agent 30 is a mixture of cement, xylene and prepolymer, 45 to 60% by weight of cement, 20 to 30% by weight of xylene and 15 to 25% by weight of prepolymer are used.

이러한 경우에는 시멘트와 프리폴리머를 합한 함유량이 60% 미만이 되면 점성이 낮아지고 강도가 저하되며, 반대로 85 중량% 초과 되면 유동성이 떨어져 심재(20)에 일정한 두께로 도포하기가 어렵다.
In this case, when the total content of the cement and the prepolymer is less than 60%, the viscosity is lowered and the strength is lowered. On the contrary, when the content exceeds 85% by weight, the fluidity is lowered and it is difficult to apply the core material 20 to a certain thickness.

결합강화제(30)를 시멘트, 자일렌, 프리폴리머 및 카보네이트가 혼합된 것을 사용할 경우 시멘트 45~60 중량%, 자일렌 20~30 중량%, 프리폴리머 15~25 중량%, 카보네이트 1~5 중량%로 한다.When a mixture of the cement, xylene, prepolymer and carbonate is used as the bonding enhancer 30, 45 to 60 wt% of cement, 20 to 30 wt% of xylene, 15 to 25 wt% of prepolymer and 1 to 5 wt% of carbonate .

본 실시예는 상기 실시예인 시멘트, 자일렌 및 프리폴리머를 혼합한 결합강화제에서 카보네이트를 더 부가한 것으로서, 카보네이트는 내충격성이 높고 내열성, 내한성이 높아 기계적 성질이 우수하므로, 카보네이트를 섞어줌으로써 컨베이어 보드의 내충격성, 내열성 및 내한성 등 기계적 성질을 더욱 향상시킬 수 있다.
In this embodiment, a carbonate is further added in the binding enhancer obtained by mixing cement, xylene and prepolymer of the above embodiment. Since carbonate has high impact resistance, high heat resistance and cold resistance, it is excellent in mechanical properties. Therefore, Mechanical properties such as impact resistance, heat resistance and cold resistance can be further improved.

상기 카보네이트의 함유량은 결합강화제(30)의 전체 중량 대비 1~5 중량%로 첨가하는 것이 바람직한데, 1 중량% 이하가 될 경우 카보네이트의 특성이 제대로 발휘되기 어렵고, 5 중량% 이상 첨가할 경우 결합강화제의 접착성이 떨어질 수 있다.
The content of the carbonate is preferably 1 to 5% by weight based on the total weight of the binder enhancer 30. When the content of the carbonate is 1% by weight or less, the properties of the carbonate are hardly exhibited. When 5% The adhesion of the reinforcing agent may be deteriorated.
