A tube-joining apparatus capable of stably and reliably joining tubes where liquid is contained and sealed. In a tube joining apparatus, a first clamp ( 6 ) and second clamp ( 7 ) for pressing and holding tubes ( 8, 9 ) are arranged in a contact state. When a second moving mechanism is driven to separate the second clamp ( 7 ) from the first clamp ( 6 ), the first clamp ( 6 ) is slid on the tubes by a shaft ( 121 ) supporting the first clamp ( 6 ) in a vertically movable manner and is moved from a first position (P 1 ) to a second position (P 2 ). The tubes are squeezed with a pressing force being gradually increased while the tubes are slid between slants ( 67, 77 ) of an engagement portion ( 68 ) and second engagement portion ( 78 ). Residual liquid in the tubes is removed from inside the tubes by the squeezing operation of the first clamp 6 . The tubes from which the residual liquid is removed are cut by a cutting plate ( 41 ), the tubes are moved by first and second moving mechanisms, and then the tubes are joined. |
