関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a tubular member cutting device suitable for use in cutting copper pipes and the like having a coating layer formed on the outer periphery thereof.
例えば、冷暖房用設備に用いられる断熱被覆銅
管を製造する場合には、主として上記被覆層の品
質を均一に保持するため、先ず長尺の銅管の外周

の後これらを所定長さ毎に切断する方法が採られ
ている。すなわち、具体的には、リール等に巻回
されるような、数千メートルに及ぶ長尺の銅管に
ついては長尺のままで、また、第３図に示すよう

断熱被覆層６を形成している。
For example, when manufacturing heat-insulating coated copper pipes for use in air-conditioning equipment, first a synthetic resin heat-insulating coat is applied continuously around the outer periphery of a long copper pipe, primarily to maintain uniform quality of the coating layer. A method is adopted in which layers are formed and then cut into predetermined lengths. Specifically, long copper pipes that are several thousand meters long, such as those wound on reels, remain long, and as shown in Figure 3, they can be directly wound in units of several meters. Regarding the copper pipes 1 and 2 manufactured as pipes, insertion parts 4,
They are connected one after another using iron connectors 5 having numerals 4 formed thereon, and the heat insulating coating layer 6 is formed on the outer periphery of each of the long pieces.
そして、このようにして被覆層が形成された銅
管のうち前者の長尺のものについては所定長さ毎
に切断し、また後者の接続したものについては、
上記接続具５の中央部３外周の被覆層６のみを全
周に亘つて切断し、上記接続具５の差込部４，４
をそれぞれ銅管１，２の端部から引抜くことによ
り各直管毎に切り離している。 Of the copper tubes on which the coating layer has been formed in this way, the former long ones are cut into predetermined lengths, and the latter connected ones are cut into pieces.
Only the coating layer 6 on the outer periphery of the central part 3 of the connecting tool 5 is cut around the entire circumference, and the insertion parts 4, 4 of the connecting tool 5 are cut.
Each straight pipe is separated by pulling it out from the end of the copper pipes 1 and 2, respectively.
ところで、従来より上記長尺の銅管を所定長さ
毎に切断する場合には、上記銅管の両側部に対向
配置された一対の切断刃を有し、これら切断刃に
よるせん断で上記銅管を切断する切断機が用いら
れている。 By the way, conventionally, when cutting the above-mentioned long copper pipe into predetermined lengths, a pair of cutting blades are arranged oppositely on both sides of the above-mentioned copper pipe, and the copper pipe is cut by shearing by these cutting blades. A cutting machine is used to cut the.
しかしながら、上記従来の切断機は、上述した
後者のもののように、接続具５の中央部３外周の
被覆層６のみを切断する場合には使用することが

ばならないという問題があつた。加えて、上記直
管を切り離す作業は専ら人手に頼るものであるた
め多大の工数を要して非能率であり、特にこの種
の作業の省力化及び自動化が望まれていた。 However, the above-mentioned conventional cutting machine cannot be used when cutting only the coating layer 6 on the outer periphery of the central portion 3 of the connecting tool 5, like the latter one mentioned above. Therefore, in such cases, only the coating layer 6 on the outer periphery of the central portion 3 of the connector 5 is cut by a worker using a special cutting jig. For this reason, in the past, there was a problem in that a line for cutting the long copper pipe and a line for separating the connected straight pipe had to be provided separately. In addition, since the work of separating the straight pipes is entirely manual, it requires a large amount of man-hours and is inefficient, and labor-saving and automation of this type of work has been particularly desired.
この発明は上記事情に鑑みてなされたもので、
