Description
본 발명은, 전동식 사출성형기에 동력전달구조에 관한 것으로, 특히, 수평구동모터에서 동력을 전달받아서 직선운동을 하는 사출구동부와 수지를 이동하기 위한 스크류 사이에 회전구동모터에 의하여 회전하면서 수평이동하는 스플라인축을 구비하여서 회전구동모터가 수평이동을 하지 않아도 회전동력을 전,후방향으로 스크류에 전달하므로 직선운동과 회전운동을 간단하고 효율적인 구성으로 수행하도록 하는 스크류 회전구동장치가 고정된 사출성형기에 관한 것이다.The present invention relates to a power transmission structure to an electric injection molding machine, and in particular, horizontal movement while rotating by a rotation drive motor between a screw for moving the resin and the injection drive unit for linear movement received power from the horizontal drive motor The injection molding machine with a fixed screw rotation drive device is provided with a spline shaft so that the rotational power is transmitted to the screw in the forward and backward directions without the horizontal movement. will be.
일반적으로, 사출성형기는 스크류를 직선운동과 회전운동을 하도록 하여서 수지를 용융하고, 용융된 수지를 금형 내부로 사출하여서 원하는 형상의 제품을 만들게 되는 것으로서, 회전운동을 담당하는 모터와 직선운동을 담당하는 모터등의 두가지 구동원을 가지고서 작동하게 된다.In general, the injection molding machine melts the resin by causing the screw to move linearly and rotates, and injects the melted resin into the mold to produce a product of a desired shape. It operates with two driving sources such as a motor.
하나의 스크류가 직선운동과 회전운동을 병행해야 하므로, 회전운동을 담당하는 모터는 스크류와 같이 움직이게 된다.Since one screw has to carry out a linear motion and a rotational motion, the motor responsible for the rotational motion moves with the screw.
이와 같이, 종래의 구성은 회전운동을 담당하는 모터는 사출구동부와 같이 가이드부재에 의하여 전,후진방향으로 수평으로 이동하면서 동작이 이루어지도록 구성되어진다.As such, the conventional configuration is configured such that the motor in charge of the rotational movement is moved horizontally in the forward and backward directions by the guide member like the injection driving unit.
그런데, 상기한 바와 같이, 종래의 사출성형기는 사출구동부 자체가 수평으로 이동하게 되는 구성으로서, 이 사출구동부는 중량이 많이 나가는 중량물이기 때문에 정밀하게 제어하기 어려울 뿐만아니라 서보모터를 지지하는 볼스크류에 많은 하중이 작용하는 문제점을 지닌다.However, as described above, the conventional injection molding machine is a configuration in which the injection driving unit itself moves horizontally, and since the injection driving unit is a heavy object that weighs a lot, it is difficult to precisely control the ball screw supporting the servomotor. Many loads have a problem.
즉, 회전운동을 담당하는 회전구동모터가 이동되어야 하므로 이동중량이 커질 수 밖에 없어 관성력에 의한 위치제어의 정확도가 저하되어진다.That is, since the rotation drive motor responsible for the rotational movement must be moved, the moving weight is inevitably increased, and the accuracy of position control by the inertial force is reduced.
또한, 사출성형기의 구조가 전체적으로 복잡하여지므로 제조단가가 증가하는 문제점을 지닌다.In addition, since the structure of the injection molding machine becomes complex as a whole, there is a problem in that manufacturing cost increases.
본 발명은 이러한 점을 감안하여 안출한 것으로서, 수평구동모터에서 동력을 전달받아서 직선운동을 하는 사출구동부와 수지를 용융하기 위한 스크류사이에 회전구동모터에 의하여 회전하는 스플라인축을 구비하여서 회전구동모터가 수평이동을 하지 않아도 회전동력을 전,후진방향으로 수평이동을 하는 스크류에 전달하므로 직선운동과 회전운동을 간단하고 효율적인 구성으로 수행하도록 하는 것이 목적이다. The present invention has been made in view of this point, the rotary drive motor is provided with a spline shaft that is rotated by a rotary drive motor between the injection drive unit for linear movement by receiving power from the horizontal drive motor and the screw for melting the resin The objective is to carry out the linear motion and the rotational motion in a simple and efficient configuration, because the rotational power is transmitted to the screw moving horizontally in the forward and backward directions without the horizontal movement.
이러한 목적은 수지주입부에 수지를 주입하여서 회전운동과 전진운동을 하여서 스크류로 수지를 이송하여서 용융하고, 금형의 내부로 주입하도록 하는 전동식 사출성형기에 있어서, 본체에 고정되어 축에 결합된 구동풀리를 회전하는 수평구동모터와; 상기 구동풀리에 감겨진 벨트에 의하여 회전하는 피동풀리에 결합된 볼너트에 나사 결합되어져서 전방 혹은 후방으로 수평 이동하는 볼스크류축과; 상기 볼스크류축의 끝단 부분에 결합되어져서 상기 스크류를 전방 혹은 후방으로 이동시키도록 하는 사출구동수단과; 상기 사출구동부와 스크류 사이에 있는 스플라인축에 결합 설치되어져서 상기 스크류에 회전동력을 가하도록 하는 스크류회전수단을 포함하여 이루어진 스크류 회전구동장치가 고정된 사출성형기를 제공함으로써 달성된다.The purpose of this is to inject the resin into the resin injection unit, the rotational movement and the forward movement in the electric injection molding machine to transfer the resin with the screw to melt and inject into the mold, the drive pulley fixed to the main body coupled to the shaft Horizontal drive motor to rotate; A ball screw shaft which is screwed to a ball nut coupled to a driven pulley which is rotated by a belt wound around the driving pulley and moves horizontally forward or backward; An injection driving means coupled to an end of the ball screw shaft to move the screw forward or backward; It is achieved by providing a fixed injection molding machine is fixed to the screw rotation drive device comprising a screw rotation means which is coupled to the spline shaft between the injection drive portion and the screw to apply a rotational power to the screw.

이하, 첨부도면에 의거하여 본 발명의 작용 및 효과를 상세하게 살펴보도록 한다.Hereinafter, the operation and effects of the present invention will be described in detail with reference to the accompanying drawings.
먼저, 본 발명에 따른 스크류 회전구동장치가 고정된 사출성형기의 사용 상태를 살펴 보게 되면, 도 5에 도시된 바와 같이, 수지주입부(18)에 저장된 수지를 전방으로 압축하여서 공급하도록 하는 동작 상태를 살펴 보면, 수평구동모터(1)를 구동하여서 구동풀리(2)에 감겨져 있는 벨트(3)를 회전하고 이 벨트(3)의 타측에 감겨져 있는 피동풀리(4)를 회전하도록 한다.First, when looking at the state of use of the injection molding machine is fixed screw rotation drive device according to the invention, as shown in Figure 5, the operating state to compress the resin stored in the resin injection portion 18 to supply the front As shown in FIG. 2, the horizontal drive motor 1 is driven to rotate the belt 3 wound around the drive pulley 2 and to rotate the driven pulley 4 wound on the other side of the belt 3.
그리고, 상기 피동풀리(4)에 나사로 결합된 볼너트(5)를 회전하여서 이 볼너트(5)에 나사축 결합된 볼스크류축(6)을 전방 혹은 후방으로 이동시키게 된다.Then, by rotating the ball nut (5) coupled to the driven pulley (4), the ball screw shaft (6) screwed to the ball nut (5) is moved forward or backward.
이와 같이, 상기 볼스크류축(6)의 전방 또는 후방이동으로 이 볼스크류축(6)의 끝단부분에 결합된 사출구동수단(20)의 하우징(28)이 전,후방으로 이동하면서 이 사출구동부(20)의 중심축(32)에 고정된 스플라인축(9)을 전,후방으로 이동하게 된다.In this way, the injection drive unit while the housing 28 of the injection drive means 20 coupled to the end of the ball screw shaft 6 is moved forward or rearward by the front or rear movement of the ball screw shaft 6. The spline shaft 9 fixed to the central shaft 32 of 20 is moved forward and backward.
결국에는 상기 스플라인축(9)에 결합된 스크류(7)를 전,후방으로 이동하게 된다.Eventually, the screw 7 coupled to the spline shaft 9 is moved forward and backward.
한편, 상기 스크류(7)를 전, 후방으로 이동하는 상태를 살펴 보면, 본체(14)에 고정된 회전구동모터(10)를 구동하면, 이에 축결합된 구동풀리(11)가 회전하게 되고, 이 구동풀리(11)에 감겨져 있는 벨트(12)가 같이 회전하면서 피동풀리(8)를 회전시키게 된다.On the other hand, looking at the state in which the screw 7 is moved to the front, rear, when driving the rotary drive motor 10 fixed to the main body 14, the drive pulley 11 is axially coupled thereto, The belt 12 wound around the drive pulley 11 rotates together to rotate the driven pulley 8.
그리고, 상기 피동풀리(8)가 회전하게 되면, 도 3 및 도 4에 도시된 바와 같이, 피동풀리(8)의 스플라인홈부(8a)에 스플라인 결합되어져 있는 스프라인축(9)을 회전하게 되므로 이 스플라인축(9)에 결합된 스크류(7)를 회전시키면 수지주입부 (18)에 저장된 수지를 전방으로 이동시키게 된다.When the driven pulley 8 is rotated, as shown in FIGS. 3 and 4, the spline shaft 9 which is splined to the spline groove 8a of the driven pulley 8 is rotated. Rotating the screw 7 coupled to the spline shaft 9 causes the resin stored in the resin injection portion 18 to move forward.
상기 피동풀리(8)의 스플라인홈부(8a)에 결합된 스플라인축(9)이 사출구동수단(20)의 전,후방 동작에 의하여 수평 이동을 하더라도 피동풀리(8)의 스프라인홈부(8a)에 의하여 회전과 동시에 전,후방으로 이동하는 것이 가능하다.Even if the spline shaft 9 coupled to the spline groove 8a of the driven pulley 8 is moved horizontally by the forward and backward movement of the injection driving means 20, the spline groove 8a of the driven pulley 8 It is possible to move forward and backward simultaneously with the rotation.

한편, 상기 사출구동수단(20)이 상기 볼스크류(6)의 작동에 의하여 전,후방으로 이동하는 경우, 하우징(28)의 외측과 본체(14)의 내측면 사이에 설치된 부시(26)에 의하여 진동과 마찰 없이 안정적으로 전,후방으로 이동하는 것이 가능하다.On the other hand, when the injection driving means 20 is moved forward and backward by the operation of the ball screw 6, the bush 26 provided between the outer side of the housing 28 and the inner surface of the main body 14 As a result, it is possible to stably move forward and backward without vibration and friction.
따라서, 상기한 바와 같이, 본 발명에 따른 스크류 회전구동장치가 고정된 사출성형기를 사용하게 되면, 수평구동모터에서 동력을 전달받아서 직선운동을 하는 사출구동부와 수지를 용융하기 위한 스크류 사이에 회전구동모터에 의하여 회전하는 스플라인축을 구비하여서 회전구동모터가 수평이동을 하지 않아도 회전동력을 전,후진방향으로 이동하는 스크류에 전달하므로 직선운동과 회전운동을 간단하고 효율적으로 수행하도록 하는 매우 유용하고 효과적인 발명이다.Therefore, as described above, when the screw rotation drive apparatus according to the present invention uses a fixed injection molding machine, the rotation drive between the injection drive unit and the screw for melting the resin linear movement by receiving power from the horizontal drive motor The spline shaft rotated by a motor provides a very useful and effective invention to perform linear and rotary motions simply and efficiently because the rotary drive motor transmits the rotational power to the screw moving in the forward and reverse directions without horizontal movement. to be.
또한, 종래의 사출구동부가 이동하는 것과 다르게 본 발명에 따른 사출구동부가 이동하는 것 없이 볼스크류과 스플라인축만 이동하면 되므로 사출구동부의 구성이 간단해지고 관성력제어가 용이하여 정밀도를 향상시킬 수 있으며, 제어동작이 비교적 쉬워지므로 제조비용을 저감하는 장점을 지닌다.In addition, since the ball screw and the spline shaft only need to be moved without moving the injection driving unit according to the present invention, unlike the conventional injection driving unit, the configuration of the injection driving unit can be simplified and the inertia force can be easily controlled to improve the precision. Since the operation becomes relatively easy, the manufacturing cost is reduced.
