목재 절단기{Power saw}Wood Cutting Machine {Power saw}

본 발명은 목재를 일정한 길이로 연속하여 절단할 수 있게 하는 목재 절단기에 관한 것이다.The present invention relates to a wood cutter that enables continuous cutting of wood to a constant length.

일반적으로 종래의 목재 절단기는 도 4에 도시한 바와 같이 목재가 안착되어 지나는 테이블(11)에 구동모터(12)를 장착하고, 상기 테이블(11)의 저면에는 원형톱(13)을 갖는 샤프트(14)를 회전 가능하게 장착하며, 상기 구동모터(12)의 구동축(12a) 및 샤프트(14)에는 풀리(15)를 고정 결합하고, 상기 풀리(15)를 벨트(16)로 연결하여 상기 구동모터(12)의 구동축(12a) 회전에 따라 원형톱(13)이 회전되면서 상기 테이블(11)에 안착되어 이송되는 목재(1)를 절단하도록 구성되어 있다.In general, the conventional wood cutting machine is equipped with a drive motor 12 on the table 11 through which the wood is seated, as shown in Figure 4, the bottom of the table 11 has a shaft having a circular saw 13 ( 14 is rotatably mounted, and the pulley 15 is fixedly coupled to the drive shaft 12a and the shaft 14 of the drive motor 12, and the pulley 15 is connected to the belt 16 to drive the drive. The circular saw 13 is rotated in accordance with the rotation of the drive shaft 12a of the motor 12, and is configured to cut the wood 1 seated on the table 11 and transported.

그러나, 이와 같은 종래의 목재 절단기(10)는 목재(1)를 절단하는 위치가 1개소로 한정되어 있기 때문에 하나의 목재를 여러 개로 절단하기 위해서는 여러 번의 절단 작업을 반복해야 하므로 시간이 많이 소요되어 생산량이 매우 적을 뿐 아니라, 수회 반복하여 절단하는 과정에서 그 치수를 일정하게 유지하는 것이 어려워서 숙련된 작업자 외에는 쉽게 할 수 없는 문제점이 있다.However, since the conventional wood cutting machine 10 is limited to one place for cutting the wood 1, in order to cut a single wood into several pieces, a plurality of cutting operations must be repeated, which takes a lot of time. In addition to the very small amount of production, it is difficult to keep the dimensions constant in the process of cutting repeatedly several times, there is a problem that can only be easily done by skilled workers.

또한, 목재가 원형톱(13)과 닿는 순간 톱날(13)의 고속 회전력에 의한 충격 및 접촉 마찰력에 의해서 목재(1)가 튀어 오르거나 절단 위치에서 이탈하여 제대로 절단되지 않는 문제가 있으므로, 목재(1)를 일일이 손으로 잡은 상태에서 밀어내면서 절단해야 하는 번거로움이 있다.In addition, there is a problem that the wood (1) springs up or breaks out of the cutting position due to the impact and contact friction force of the saw blade 13 at the moment when the wood comes in contact with the circular saw 13, the wood ( There is an inconvenience to cut while pushing 1) by hand.

또한, 목재를 절단할 때 톱밥이 비산하여 절단기 주변에 쌓이게 되어 주변을 자주 청소해야 하는 불편함이 있으며, 비산된 톱밥이 기계의 구동장치에 누적되는 경우 기계에 부하가 걸려 오작동하거나 목재의 정밀한 절단 작업을 수행할 수 없게 되는 등의 문제가 있음은 물론, 미세한 톱밥 먼지 등으로 인해 작업자의 건강을 해치는 등의 치명적인 단점이 있다.In addition, sawdust is scattered when cutting wood, which is accumulated around the cutter, which is inconvenient to clean the surroundings often.When scattered sawdust accumulates in the driving mechanism of the machine, the machine is loaded and malfunctions, or precise cutting of wood There is a problem such as not being able to perform the work, as well as a fatal disadvantage, such as damage to the health of the worker due to fine sawdust dust.

상기의 제반 문제점을 해결하기 위한 본 발명은, 단 한 번의 절단 공정을 통해서 복수 개로 커팅된 목재를 수득할 수 있으면서도, 원형톱과 목재의 접촉에 따른 충격이나 마찰력이 작용하더라도 목재가 튀거나 요동 없이 안정된 상태로 절단되며, 목재 절단시 발생하는 톱밥을 즉시 톱밥 저장소로 배출하여 톱밥의 비산을 방지할 수 있게 하는 목재 절단기를 제공하는데 그 목적이 있다.The present invention for solving the above problems, while it is possible to obtain a plurality of cut wood through a single cutting process, even if the impact or frictional force due to the contact between the circular saw and the wood without splashing or shaking It is an object of the present invention to provide a wood cutting machine that is cut to a stable state and prevents sawdust from scattering by immediately discharging sawdust generated during cutting of wood into a sawdust reservoir.
