본 발명은 벨크로파스너가 부착된 쿠션 제조장치 및 방법에 관한 것으로서, 보다 상세하게는 쿠션에 벨크로파스너를 부착시키는 과정에서 금형 내에서 벨크로파스너의 비틀림 및 요동을 방지하여, 제품의 불량률을 낮출 수 있도록 된 벨크로파스너가 부착된 쿠션 제조장치 및 방법에 관한 것이다.The present invention relates to an apparatus and a method for manufacturing a cushion having a Velcro fastener, and more particularly, to prevent twist and fluctuation of the Velcro fastener in the mold during the process of attaching the Velcro fastener to the cushion, so as to lower the defective rate of the product. The present invention relates to a cushion manufacturing apparatus and method with attached Velcro fasteners.

일반적으로 차량의 시트는 발포체로 이루어진 쿠션 위에 가죽이나 직물 등의 커버를 씌워 만들어진다. 이때, 커버가 일측으로 밀리거나 유동되는 것을 방지하기 위하여, 쿠션과 커버에는 각각 리본 형상의 벨크로파스너가 부착된다. 도 1은 종래에 쿠션에 벨크로파스너를 부착시키는 과정을 도시한 단면도로서, 이와 같이, 금형(50) 내에 발포체(100)를 주입하여 쿠션을 성형하는 과정에서, 배면에 발포층(64)이 구비된 벨크로파스너(60)를 금형(50) 내에 삽입하여, 벨크로파스너(60)의 발포층(64)과 발포체(100)를 융착시켜 접합시키고 있다.In general, a vehicle seat is made by covering a leather or fabric cover on a cushion made of foam. In this case, in order to prevent the cover from being pushed or flowed to one side, a Velcro fastener having a ribbon shape is attached to the cushion and the cover, respectively. 1 is a cross-sectional view illustrating a process of attaching a Velcro fastener to a cushion in the related art. In the process of molding the cushion by injecting the foam 100 into the mold 50, the foam layer 64 is provided on the rear surface thereof. The velcro fastener 60 thus inserted is inserted into the mold 50, and the foamed layer 64 and the foam 100 of the velcro fastener 60 are fused and joined.

이를 위하여, 벨크로파스너(60)가 금형(50) 내에서 위치 고정되어야 하며, 종래에는 도 1에서와 같이, 벨크로파스너(60)의 벨크로층(62)과 발포층(64) 사이에 금속시트(66)를 적층시키며, 금형(50) 내에 벨크로파스너(60)를 수용하도록 수직으로 입설된 리브(52)에 의해 구획된 삽입홈(54)을 형성하고, 이 삽입홈(54) 저부에 자성체(56)를 내장하여, 벨크로파스너(60)를 고정시키도록 구성되었다. 즉, 자력에의해 벨크로파스너(60)를 금형(50) 내에 고정시키는 방법이 사용되고 있었다.For this purpose, the Velcro fastener 60 must be fixed in the mold 50, and in the related art, as shown in FIG. 1, a metal sheet between the Velcro layer 62 and the foam layer 64 of the Velcro fastener 60 is formed. 66 are stacked to form insertion grooves 54 defined by ribs 52 vertically placed in the mold 50 to receive the Velcro fasteners 60, and at the bottom of the insertion grooves 54, a magnetic body ( 56), it is configured to fix the Velcro fastener (60). That is, the method of fixing the velcro fastener 60 in the metal mold | die 50 by magnetic force was used.

그러나, 금형(50) 내에 자성체(56)를 삽입하는 데 따르는 비용부담이 발생되며, 벨크로파스너(60)를 삽입홈(54)에 안착시키는 과정에서 벨크로파스너(60)가 비틀린 채로 삽입홈(54)에 부착될 우려가 있다. 또한, 금형(50)에 발포체(100)를 주입하는 과정에서 금형(50)이 발열되어, 자성체(56)의 자력이 약화되며, 이로 인해 벨크로파스너(60)가 삽입홈(54) 내에서 요동되면서 벨크로층(62)까지 발포체(100)가 침투하여 불량품이 발생되는 등의 문제점이 있다.However, a cost burden of inserting the magnetic body 56 into the mold 50 is generated, and the insertion groove 54 with the Velcro fastener 60 twisted in the process of seating the Velcro fastener 60 in the insertion groove 54. ) May be attached. In addition, in the process of injecting the foam 100 into the mold 50, the mold 50 generates heat, and the magnetic force of the magnetic body 56 is weakened, thereby causing the Velcro fastener 60 to swing in the insertion groove 54. While the foam 100 penetrates up to the velcro layer 62, there are problems such as defective products.

본 발명은 상기의 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 금형 내에서 벨크로파스너의 비틀림 및 요동을 방지하여, 제품의 불량률을 낮출 수 있도록 된 벨크로파스너가 부착된 쿠션 제조장치 및 방법을 제공하는 것이다.The present invention is to solve the above problems, an object of the present invention to prevent the twist and fluctuation of the Velcro fastener in the mold, to provide a cushion manufacturing apparatus and method with a Velcro fastener attached to be able to lower the defective rate of the product. It is.

Figure 2 is a cutaway perspective view showing the mounting portion in the mold in the manufacturing apparatus according to the invention, Figure 3 is a cross-sectional view showing a process for attaching the Velcro fastener to the cushion in accordance with an embodiment of the present invention, Figure 4 is a present invention According to a modified embodiment of the velcro fastener is a cross-sectional view showing a process of attaching to the cushion.

이를 참조하면, 상기 벨크로파스너가 부착된 쿠션 제조장치는 발포체(100)를 소정 형상으로 성형하기 위한 금형(10)을 포함하고, 이 금형(10) 내에는 발포체(100)에 일체로 융착되기 위한 벨크로파스너(20)가 안착 고정되는 안착부(12)가 구비된다. 이 안착부(12) 둘레에는 그 기단부의 폭에 비해 선단부의 폭이 협소하게 입설되는 리브(14)가 구비되며, 이 리브(14)는 벨크로파스너(20)를 하향 가압하여 안착부(12)에 고정시키는 역할을 한다.Referring to this, the Velcro fastener-attached cushion manufacturing apparatus includes a mold 10 for molding the foam 100 into a predetermined shape, and the mold 10 is integrally fused to the foam 100 in the mold 10. Velcro fastener 20 is provided with a seating portion 12 is fixed. Rib 14 is provided around the seating portion 12 in which the width of the tip portion is narrowly entered compared with the width of the base portion, and the rib 14 presses the Velcro fastener 20 downwardly to seat the seating portion 12. To lock in place.

도 2는 상기 금형 내의 안착부를 도시한 절개사시도로서, 안착부(12)는 금형(10) 내에 부착되는 하부판(16)과, 이 하부판(16) 둘레에 입설되는 리브(14)로 이루어진다. 이 리브(14)는 벨크로파스너(20)의 발포층(24) 중간 정도에 이르는 수직 높이를 가지며, 바람직하게 도 2 및 도 3에서와 같이, 안착부(12)의 폭 방향 내측으로 경사지게 입설되고, 도 4에서와 같이, 선단부에 걸림턱(18)이 내향 돌출된 형태로 수직 입설될 수 있다. 또한, 경우에 따라 기단부에 비해 선단부의 폭이 협소하게 만곡되어 입설될 수도 있다. 리브(14)의 기단부 폭은 벨크로파스너(20)를 완전히 수용할 수 있도록, 벨크로파스너(20)의 폭보다 소정 간격 넓게 형성되며, 선단부 폭은 벨크로파스너(20)의 발포층(24)보다 좁은 폭을 형성한다. 따라서, 벨크로파스너(20)가 도 3 및 도 4의 확대도에서와 같이, 안착부(12)에 끼워지면, 리브(14)의 상부에서 벨크로파스너(20)의 발포층(24)을 하향 가압하여, 벨크로파스너(20)를 안착부 내에 고정시킨다. 이렇게 고정된 벨크로파스너(20)는 금형(10)에 발포체(100)를 주입하여, 발포체(100)와 발포층(24)이 융착되는 과정에서, 금형(10)의 발열에 의한 영향을 받지 않고, 안착부(12) 내에 요동없이 고정될 수 있다.FIG. 2 is a cutaway perspective view of a seat in the mold, wherein the seat 12 comprises a lower plate 16 attached to the mold 10 and a rib 14 recessed around the lower plate 16. The rib 14 has a vertical height reaching to about the middle of the foam layer 24 of the Velcro fastener 20, and is preferably inclined inward in the width direction of the seating portion 12, as shown in Figs. As illustrated in FIG. 4, the locking jaw 18 may be vertically vertically protruded inwardly. In addition, in some cases, the width of the tip portion may be narrowly curved compared to the base portion, and may be vertically entered. The proximal end width of the rib 14 is formed wider than the width of the Velcro fastener 20 so as to completely accommodate the Velcro fastener 20, and the distal end width is narrower than the foam layer 24 of the Velcro fastener 20. To form a width. Thus, when the velcro fastener 20 is fitted to the seating portion 12, as in the enlarged view of FIGS. 3 and 4, the foam layer 24 of the velcro fastener 20 is pressed downward from the top of the rib 14. Thus, the Velcro fastener 20 is fixed in the seating portion. The fixed Velcro fastener 20 injects the foam 100 into the mold 10, so that the foam 100 and the foam layer 24 are fused, without being affected by the heat generation of the mold 10. It can be fixed without shaking in the seating portion 12.

이러한 장치를 사용하여, 벨크로파스너가 부착된 쿠션을 제조하는 방법은 다음과 같다. 우선, 상기 안착부(12) 내에서 벨크로파스너(20)가 하향 가압될 때, 벨크로파스너(20)의 굽힘을 방지하기 위하여, 벨크로층(22)과 발포층(24) 사이에 벨크로층(22)보다 높은 강도를 갖는 보강스트립(26)을 접착한다. 이 보강스트립(26)으로는 강성재질의 필름을 사용하여, 벨크로층(22)과 발포층(24) 사이에 용이하게 접착된다. 이렇게 제작된 벨크로파스너(20)를 벨크로층(22)이 하방을 향하도록 상기 금형(10) 내의 안착부(12)에 안착 고정시킨다. 다음에, 금형(10) 내로 발포체(100)를 주입하여, 벨크로파스너(20)의 발포층(24)을 발포체(100)에 융착시켜 접합한다. 그리고, 발포체(100)를 응고시켜 벨크로파스너(100)가 일체로 부착된 쿠션을 제조한다.Using such a device, a method of manufacturing a cushion with Velcro fasteners is as follows. First, when the Velcro fastener 20 is pressed downward in the seating part 12, in order to prevent bending of the Velcro fastener 20, the Velcro layer 22 is formed between the Velcro layer 22 and the foam layer 24. A reinforcing strip 26 having a higher strength than) is bonded. As the reinforcing strip 26, a rigid film is used to easily adhere between the velcro layer 22 and the foam layer 24. The Velcro fastener 20 thus manufactured is seated and fixed to the seating portion 12 in the mold 10 so that the Velcro layer 22 faces downward. Next, the foam 100 is injected into the mold 10, and the foam layer 24 of the velcro fastener 20 is fused and bonded to the foam 100. Then, the foam 100 is solidified to produce a cushion to which the Velcro fastener 100 is integrally attached.
