本発明は小麦粉などの輸送管として用いられる薄肉パイ
プを切断するためのパイプ切断機に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a pipe cutting machine for cutting thin-walled pipes used as transport pipes for flour and the like.
(従来技術)
小麦の製粉工場においては、小麦粉を輸送するのに直径
150〜200m5、肉厚0.8〜2.。(Prior art) In a wheat flour mill, a diameter of 150 to 200 m5 and a wall thickness of 0.8 to 2.0 m are used to transport flour. .
I程度の金属製の薄肉パイプが用しくられている。Thin-walled metal pipes of grade I are used.
このパイプを適当な長さで切断し、粛手などで継ぎ合わ
せて輸送路が形成される。This pipe is cut to an appropriate length and then joined together using a handshake to form a transport route.
パイプ切断機はこの薄肉パイプを切断するのに用いられ
るもので、この種の装置には高速で回転する回転刃(簿
い円板状の砥石)が備えられ、装置の固定部にパイプを
両側から万力などで挟んで固定した後、回転刃をパイプ
に当てて切断する。A pipe cutting machine is used to cut this thin-walled pipe, and this type of equipment is equipped with a rotary blade (a disc-shaped grindstone) that rotates at high speed, and the pipe is attached to the fixed part of the equipment on both sides. After securing it in a vise, place a rotary blade against the pipe and cut it.
しかし、この切断機を使ってもパイプを一回で切断する
のは難しい、それはパイプが薄肉であるため、半分以上
切断されるとパイプを保持するのが難しくなり、また回
転刃がパイプの切断された個所によって両側から挟まれ
たりするからである。However, even with this cutting machine, it is difficult to cut the pipe in one go, because the pipe is thin, and if more than half of the pipe is cut, it becomes difficult to hold the pipe, and the rotary blade does not cut the pipe. This is because it may be pinched from both sides depending on the location where it was touched.
そのため、この種の切断機を用いてパイプを切断すると
きは、ある程度まてパイプを切断した後、固定部の万力
をゆるめてパイプを囲わし、切断部を移動させて再び万
力で締めて回転刃を当てるといった作業を2〜3度繰り
返している。したがって、パイプの切断作業はかなり煩
わしく、また高速で回転する回転刃の前で2〜3度バイ
ブをセットし直すことは安全上も好ましくなかった。Therefore, when cutting a pipe using this type of cutting machine, after cutting the pipe for a certain amount of time, loosen the vise on the fixed part to surround the pipe, move the cut part, and tighten the vise again. This process is repeated two to three times. Therefore, the pipe cutting operation is quite troublesome, and it is not desirable from a safety standpoint to reset the vibrator two or three times in front of a rotating blade that rotates at high speed.

The support base 2 is fixedly attached to the pedestal 4, and the support base 3 is slidably attached to the pedestal 4. Rollers 2a, 2b, and 3a are rotatably provided at locations where the support base 2.3 contacts the pipe 1, and the pipe 1 is supported at three points by these rollers. If the diameter of the pipe l is different, the support stand 3 is moved and adjusted, and then the nut 5 is tightened to fix the support stand 3. As shown in FIG. 2, a plurality of these support stands 2.3 are installed at intervals in the longitudinal direction of the pipe l.

。The rod 12 is rotatably attached to a support shaft 14 of a column 13 erected on the pedestal 4, and has a handle 15 formed at its tip. A balance weight 16 whose attachment position is adjustable is provided at the other end of the rod 12. The handle 15 side of the rod 12 is made of rubber (or other elastic material).
A roller 16 is provided, and the roller 16 is rotated by a small motor 18 installed on the rod 12 via a belt 17 (the belt 17 and the small motor 18 are omitted in FIG. 2). may be driven by a motor built into the roller instead of using a belt, or may be driven by a belt from outside the device. part is locked. That is, an elongated hole 9a is formed at the tip of the arm 9, and this elongated hole 9a engages with the shaft 19. Rod 12
When pushed down in the direction of the arrow in FIG.
While sliding, the arm 9 is pushed down counterclockwise against the spring 11, and the rotary blade 16 moves toward the pipe l side.

くので、スムーズに切断されていく。Next, when the operator grips the handle 15 and lowers the rod 12, the motor 7 and the small motor 18 are driven, and the blade 6 and roller 16 rotate once. When the rod 12 is lowered further, the arm 9 is pushed by the shaft 19, and the rotary blade moves to the first position.
As shown by the chain line A in the figure, it moves to the pipe I side, and cutting of the pipe I is started. When the rod 12 is lowered further, the roller 16 moves toward the pipe 1 as shown by the m line B in FIG.
, and the pipe 1 begins to rotate. At this time, roller 1
6 is attached so as to be in contact with the pipe 1 almost directly above the pipe 1. Since the pipe l is cut while rotating, it is cut smoothly.
切断が終了したら杆12を上げ、もとの位置に戻す、こ
れによりモータ7および小型モータ18は停止するよう
になっている。When cutting is completed, the rod 12 is raised and returned to its original position, thereby stopping the motor 7 and the small motor 18.

することができる。The balance weight 16 is used to balance the vertical movement of the rod 12, and by appropriately adjusting its position, for example, when the rod 12 is raised, it remains in the raised position, and when lowered, it remains in the lowered position. It can be made to stay in place.
以上のように、本発明によるパイプ切断機、を用いれば

であるため、切粉の発生場所が変わらず、集塵も簡単に
効率よくできる。As described above, by using the pipe cutting machine according to the present invention, pipes can be easily cut, and safety is improved without the need to reset pipes many times as in the past. Furthermore, by using the cutting machine shown in the example, it is possible to easily cut pipes of different diameters, and since the contact position between the rotary blade and the pipe is always the same, the location where chips are generated changes. Dust collection can be done easily and efficiently.

に構成してもよい。In the above embodiment, the pipe 1 is rotated by the rollers 16 after the pipe 1 has been cut to a certain extent, but the timing at which the rollers 16 start rotating is not particularly limited. The timing at which the rollers 16 come into contact with the pipe 1 can be easily determined by the diameter of the rollers 16, the length of the rod 12, etc., but it is possible to keep the pipe rotating. Good too.
