본 고안은 공작기계의 공작물 운반장치에 관한 것으로서, 특히 상하로 동작되는 슬라이드의 길이를 축소함과 동시에 구동속도를 증가시켜 공작기계로부터 자동으로 반입, 반출하는 운반장치의 개선에 관한 것이다.The present invention relates to a workpiece conveying device of a machine tool, and more particularly, to an improvement in a conveying device which is automatically loaded and unloaded from a machine tool by increasing the driving speed while reducing the length of a slide operated up and down.

종래의 공작게의 공작물 운반장치는 공작기계의 상부에 설치되어 좌우로 이송되는 본체에 서보모터를 고정하고 그 서보모터의 회전이 다수개의 기어를 통해 래크에 치합된 종동기어에 전달되면 종동기어의 회전을 래크에서 직선운동으로 전환시켜 래크가 고정된 슬라이더를 상하로 이송시키므로 공작물을 반입, 반송하는 것이며, 상하로 이송되는 슬라이더는 가이드블럭과 가이드레일에 의해 안내되도록 하였으나, 이러한 종래기술은 슬라이더에 고정된 래크와 종동기어의 치합작용에 의해 슬라이더가 슬라이더가 상하로 이송되는 것이므로 슬라이더가 상하 이송길이 만큼 길어져야 할뿐만 아니라 이로인하여 이송시간이 길어지는 결점이 있었다.The conventional work piece conveying device of the machine tool is installed on the upper part of the machine tool to fix the servo motor to the main body which is transported from side to side, and when the rotation of the servo motor is transmitted to the driven gear meshed with the rack through a plurality of gears, The rotation is shifted from the rack to the linear motion to transport the slider fixed to the rack up and down to carry and convey the workpiece, the slider transported up and down is guided by the guide block and the guide rail, but this prior art Because the slider moves the slider up and down due to the engagement of the fixed rack and the driven gear, the slider has to be extended as long as the up and down conveying length, and thus the feeding time is long.

이에 본 고안은 상기와 같은 제반 문제점을 고려하여 안출된 것으로서, 그 목적은 슬라이더의 길이를 줄여 부피를 감소함과 동시에 이송속도를 증가시켜 생산성을 향상시킬 수 있는 공작기계의 공작물 운반장치를 제공함에 있다.The present invention has been made in view of the above-mentioned problems, and its object is to provide a workpiece conveying device for a machine tool which can improve productivity by reducing the length of the slider and reducing the volume and increasing the feed rate. have.

이하, 본 고안을 첨부도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail by the accompanying drawings.

제1도는 본 고안의 외관 구성을 보인 정면도로서, 본체(30)에 고정슬라이더(20)가 수직방향으로 고정 설치되있고, 이 고정슬라이더(20)에 중간슬라이더(10) 및 상부슬라이더(23)가 이동가능하게 연결되는데, 상기 중간 슬라이더(10)는 제2도에 도시된 바와같이 상단 일측에 브라켓(6)이 고정되고, 본체(30)에 고정된 서보모터(1)의 원동기어(2)에 치합되는 종동기어(3)의 회전에 의해 볼스크류의 길이방향(수직방향)으로 승강하도록 구성된다. 그리고 제3도 및 제4도에 상세히 도시된 바와같이 상기 고정슬라이더(20)에는 가이드레일(22)과 래크(21)가 고정되어 있고, 중간슬라이더(10)의 양측에는 상기 가이드레일(22)에 슬라이드 접촉하는 가이드블럭(11)(12)이 고정되며, 그 중간슬라이더(10)의 상하측에는 각각 고정축(13)(13')이 회전가능하게 설치되어 있고, 이 고정축(13)(13')상에는 일측에 체인기어(14)(14')가 일체로 형성된 피니언(15)(15')이 회전가능하게설치되어 있다. 상기 피니언(15)은 상기 고정슬라이더(20)상의 래크(21)에 치합하게 되고, 상기 각 체인기어는 체인(16)에 연결되어 상호 연동하게 된다. 그리고 상부슬라이더(23)에는 상기 가이드블럭(11)(12)에 슬라이드 접촉하는 가이드레일(25)이 고정되며, 상기 피니언(15')에 치합되는 래크(24)가 설치된다.1 is a front view showing the appearance configuration of the present invention, the fixed slider 20 is fixed to the main body 30 in the vertical direction, the intermediate slider 10 and the upper slider 23 to the fixed slider 20 Is movably connected. The intermediate slider 10 has a bracket 6 fixed to one side of the upper end as shown in FIG. 2, and the motive gear 2 of the servo motor 1 fixed to the main body 30. It is configured to move up and down in the longitudinal direction (vertical direction) of the ball screw by the rotation of the driven gear (3) meshed with). As shown in detail in FIGS. 3 and 4, guide rails 22 and racks 21 are fixed to the fixed slider 20, and the guide rails 22 are formed at both sides of the intermediate slider 10. The guide blocks 11 and 12 for sliding contact with each other are fixed to each other, and fixed shafts 13 and 13 'are rotatably provided on the upper and lower sides of the intermediate slider 10, respectively. On the 13 'side, pinions 15 and 15' on which one side of the chain gears 14 and 14 'are integrally installed are rotatably installed. The pinion 15 is engaged with the rack 21 on the fixed slider 20, and each chain gear is connected to the chain 16 to interlock with each other. In addition, the upper slider 23 is fixed with a guide rail 25 in sliding contact with the guide blocks 11 and 12, and a rack 24 engaged with the pinion 15 ′ is installed.

이와같이 구성된 본 고안은 서보모터(1)의 동력을 원동기어(2)와 종동기어(3)을 통해 볼스크류(4)에 전달하면 볼스크류(4)에 결합된 볼너트(5)가 상하로 이동되면서 브라켓(6)에 고정된 중간슬라이더(10)를 상하로 이송시킨다.According to the present invention configured as described above, when the power of the servomotor 1 is transmitted to the ball screw 4 through the motive gear 2 and the driven gear 3, the ball nut 5 coupled to the ball screw 4 moves up and down. While moving, the intermediate slider 10 fixed to the bracket 6 is transferred up and down.

그리고 중간슬라이더(20)가 이송중인 상태에서 중간 슬라이더(10)의 상부에 위치하는 고정축(13)에 설치된 피니언(15)이 고정슬라이더(20)의 래크(21)에 의해 회전을 하게 되고, 이회전은 체인기어(14)(14')와 체인(16)의 전동에 의해 하부에 위치하는 고정축(13')에 설치된 피니언(15')을 회전시키게 된다. 따라서 피니언(15')에 치합된 래크(24)가 이동하게 되므로 상부슬라이더(23)가 승강하게 된다.And the pinion 15 installed on the fixed shaft 13 located on the upper part of the intermediate slider 10 while the intermediate slider 20 is being transferred is rotated by the rack 21 of the fixed slider 20, This rotation rotates the pinion 15 'installed on the fixed shaft 13' located below by the chain gear 14, 14 'and the chain 16. Therefore, the rack 24 engaged with the pinion 15 'is moved so that the upper slider 23 moves up and down.

상기 상부슬라이더의 승강량은 상기 중간슬라이더의 승강량에 정비례하는 양만큼 이동하게 될것이다.The lifting amount of the upper slider will move by an amount proportional to the lifting amount of the intermediate slider.

따라서, 상부 슬라이더(23)가 상하로 이송되면서 공작물(29)을 반입, 반송할 수 있게 되고, 체인기어(14)(14')와 체인(16)에 의해 등속으로 회전하는 피니언(15)(15')이 중간슬라이더(10)와 상부슬라이더(23)의 이송 속도를 동일하게 유지시키므로 공작물(29)을 이송시키는 상부슬라이더(23)는 자신의 이송속도에 중간슬라이드(10)의 이송속도가 더해지게 되어 2배의 속도로 공작물(29)을 반입, 반송시키는 것이다.Accordingly, the upper slider 23 is conveyed up and down, and thus the workpiece 29 can be carried in and conveyed, and the pinion 15 rotating at constant speed by the chain gears 14 and 14 'and the chain 16 ( 15 ') maintains the same feed speed of the intermediate slider 10 and the upper slider 23, the upper slider 23 for feeding the workpiece 29 has a feed rate of the intermediate slide 10 at its own feed rate. It adds and conveys and conveys the workpiece | work 29 at twice the speed.

한편, 공작물(29)을 이송시키는 상부슬라이더(23)는 자신의 이송거리에 중간슬라이더(10)의 이송거리를 합한 총이송거리를 이송하게 되므로 상부슬라이더(23)의 길이를 종래보다 작게 구성할 수 있는 것이다.On the other hand, the upper slider 23 for transporting the workpiece 29 is to transfer the total transport distance sum of the transport distance of the intermediate slider 10 to its own transport distance to configure the length of the upper slider 23 smaller than conventional It can be.

상술한 바와같이 본 고안은 고정슬라이더에 대해 중간슬라이더와 상부슬라이더가 동시 승강가능하게 구성하여 공작물을 이송시키는 상부슬라이더를 간접 이송시키므로써 슬라이더의 크기를 반으로 줄임과 동시에 이송속도를 약 2배정도로 높여 생산성을 향상시킬 수 있는 효과를 갖는다.As described above, the present invention configures the intermediate slider and the upper slider to simultaneously lift and lower the slider to reduce the size of the slider in half and simultaneously transfer the feed speed by about 2 times. Increase the productivity.
