In addition, a position beam device 920 may be installed on an upper surface of any one of a plurality of wings of the first star wheel blade 111. Assuming that the water supply hole 900 is installed on the first wing, the position beam device 920 is installed on the second wing, and the first and second wings are parallel to the upper surface of the first star wheel blade 111. It can be located on a virtual straight line.

In addition, a beam detector 930 may be installed on the upper surface inside the housing. The beam detector 930 and the position beam device 920 are positioned on an imaginary straight line parallel to the longitudinal direction of the first gate rotation axis 110. The position beam device 920 outputs a beam in an upward direction. Then, the beam detector 930 receives the beam output from the position beam device 920.

If, when the first wing is a single-beam rotor 21 in a state where the beam detector 930 is installed on the upper surface of the position beam device 920, the beam detector 930 is the position beam device 920 ) When the beam is received, the first wing and the single-screw rotor 21 will be engaged with each other, but if the beam detector 930 is installed at other locations, the first wing and the single-screw rotor 21 ), The beam detector 930 may receive the beam from the position beam apparatus 920 at a time when the meshes are not engaged with each other. The position of the beam detector 930 may be determined in consideration of the size and internal shape of the housing and the time it takes for the beam detector 930 to receive the beam and control the guide unit 920, which will be described later.

As the rotation speed of the first gate rotor 110a increases, the number of times the beam detector 930 detects the beam during the same period increases. When the number of beams received per second is greater than or equal to a preset value based on the number of beams received from the position beam device 920 per second, the beam detector 930 rotates the guide unit 910 at a predetermined angle to provide a water supply hole ( The water introduced into the 900) can be directly transferred to the point where the first wing of the first gate rotor 110a and the single screw rotor 22 match along the moisture supply hole 900. This embodiment can reduce the complexity of manufacturing the first gate rotor 110a by allowing the water supply hole 900 to be formed only in one of the wings of the first gate rotor 110a. And, for example, the first blade and the single screw rotor 22 can supply the lubricating water at the desired timing exactly, such as when the first blade and the single screw rotor 22 are mated.
