It becomes unnecessary and downsizing is achieved, and the assembly equipment cost is reduced. At this time, since the rotary encoder 5 is provided on the hose introduction side of the hose feed mechanism 4, the hose feed side of the hose feed mechanism 4 is provided. Even if the vacuum hose H between the connector portion C and the connector portion C is stretched, the hose length is accurately measured.

When the tip of the vacuum hose H comes into contact with the plate 94, the air chuck 95 is operated to grip the tip of the vacuum hose H, and the lubricant supply section 98 of the plate 94 is pressed against the tip surface of the vacuum hose H. Then, the lubricant is supplied, and thereafter, the hose feeding operation, the cutting operation, and the hose assembling operation by the handling robot described above are sequentially repeated.

As described above, also in the hose cutting device 81, the vacuum hose H is automatically assembled, and the vacuum hose H is cut on the device main body 92. Since a part for storing the vacuum hoses H together is not necessary, the size can be reduced, and the assembly equipment cost can be reduced. In addition, the hose cutting device 81 only cuts the vacuum hoses H. Since the hose H is attached to the sleeve by the handling robot, the cycle time can be shortened by dividing the work.

Since the slider body 88 is attached to the slider 88, the predetermined length of the vacuum hose H is set by the movement of the slider 88 by numerical control, and the hose length is set accurately. Will be seen.
