First, here, the first to third spiral conveying devices 15A
The basic structure of ~ 15C will be described. Since the first to third spiral transfer devices 15A to 15C have the same structure, the same reference numerals are given and description thereof will be omitted.

As shown in FIGS. 1 to 3, a rotary drive motor (FIG. 2) rotates a rotary drum 21 around the vertical axis O at a constant speed in the direction of arrow A, and an outer peripheral portion of the rotary drum 21. It is configured with a spiral guide 22 which is externally fitted and arranged with a certain gap to form a spiral conveyance path 20. The rotary drum 21 has a plurality of engaging grooves 23 formed in the outer peripheral portion thereof in parallel with the vertical axis O so as to be engageable with the outer peripheral portion of the cap C and capable of sliding the cap C in the vertical direction. Are formed at regular intervals. Further, the spiral guide 22 is formed in an L-shaped cross section by a support portion 22a that guides the closure (upper surface) of the cap C and a side wall portion 22b that regulates the side portion of the cap C. Further, the support portion 22a adjacent to the upper portion restricts the cap C from protruding upward, and a top guide 24 for preventing the cap C from protruding is provided at the uppermost stage where the upper portion is opened. Further, the intervals of the engaging grooves 23 are set such that the engaged cap C
Are set so as not to contact the adjacent caps C. Further, the lower end portion of the spiral guide 22 is configured as the cap inlet 25A, and the upper end portion is formed at the cap outlet 2A.
5B, which is configured to prevent the cleaning water that has washed the cap C of the inlet side spiral transfer path 20 from flowing down and contaminating the cap C of the outlet side transfer path 20.

In the above construction, when the rotary drum 21 is rotated at a constant speed in the direction of the arrow A and the cap C is supplied from the cap inlet 25A for each engagement groove 23, the cap C pivots according to the turning of the engagement groove 23. At the same time, it is guided by the spiral guide 22 and ascends along the engaging groove 23, and is moved along the spiral transport path 20. This spiral transport path 2
When 0, the cap C is held for a predetermined time, and washing, sterilization and sterilization are performed within this holding time. Further, since the adjacent caps C do not come into contact with each other, the caps C can be transported smoothly and reliably, and the caps C will not be clogged.

In this sterilization facility, the first to third spiral conveying devices 15A to 15C are incorporated in the sterile water cleaning unit 16, the chemical liquid cleaning unit 17, and the finish cleaning unit 18, respectively. Further, in the aseptic water cleaning unit 16, the chemical cleaning unit 17, and the finish cleaning unit 18, the cap C is cleaned, and therefore it is necessary to dispose a chemical liquid injection nozzle, which will be described later, in the spiral transport path 20, but here the spiral is used. The guides 22 are respectively incorporated in the shape guides 22, and only the arrangement of the injection nozzles and the length of the spiral transfer path 20 are different, and the other configurations are the same. Therefore, only the chemical cleaning unit 17 will be described here. The description of the sterile water cleaning unit 16 and the finishing cleaning unit 18 will be omitted.

As shown in FIGS. 2 and 3, in the chemical cleaning section 17, the rotary drum 21 is rotatably supported by a rotary shaft 33 via a bearing 34 in a casing 32 supported by a plurality of legs 31. The upper end of the rotary shaft 33 penetrates the casing 32 and is connected to the output shaft of the rotary drive motor 35 with a reduction gear. An inlet star wheel device 12a is disposed in an opening formed in the lower portion of the casing 32 corresponding to the component inlet 25A, and the upper component inlet 2 is provided.

The bottom surface of the is slanted to form a chemical solution discharge port 36 at the lower end, and a chemical solution discharge hose 37 or a pipe is connected.
The spiral transport path 20 is composed of a lowermost preliminary cleaning path portion 20a, an intermediate main cleaning path portion 20b, and an upper finishing cleaning path portion 20c. The spiral guide 22 is held on the inner peripheral portion of the casing 32 via a plurality of mounting members 38.

The main cleaning path portion 20 of the spiral guide 22
As shown in FIGS. 4 and 5, at b, a liquid side passage 41 is formed inside the side wall portion 22b along the circumferential direction, and the first liquid supply pipe 43A is connected thereto. A large number of side surface outer surface injection nozzles (holes) 42A, which are communicated with the injection liquid supply passage 41, are formed on the inner peripheral surface of the side wall portion 22b at regular intervals, and cut lines of the cap C (when the cap is first opened). It is formed at a position facing the line Ca that separates the container side and the cap body from each other, and in the tangential direction of the cap C. This is because when the cap C is conveyed along the spiral conveyance path 20, the outer peripheral surface of the cap C is brought into sliding contact with the side wall portion 22b, and the friction force causes the cap C to rotate in the direction shown in FIG. Therefore, the chemical liquid is tangentially sprayed from the side outer surface injection nozzle 42A, and the rotation movement of the cap C is further promoted, and the chemical liquid accumulated in the mouth is effective. The bubbles adhered to the inner surface can be removed by fluidizing and stirring.

Further, a bottom passage 45 is formed in the support portion 22a, and a second liquid supply pipe 43B is connected to the support portion 22a. The bottom outer surface injection nozzle (hole) 42B and the inner surface communicating with the bottom passage 45 are connected to the support portion 22a. An injection nozzle (hole) 42C is formed. That is, the bottom outer surface injection nozzle 42B is
The inner surface injection nozzles 42C are formed at regular intervals at positions facing the center of the upper surface of the cap C, and the inner surface injection nozzles 42C are formed at regular positions at positions where the mouth portion of the cap C of the lower spiral transport path 20 passes. As shown by phantom lines in FIGS. 4 and 5, it is also possible to form the cleaning liquid injection nozzle 46 that opens in the engagement groove 23 by the rotary drum 21 and supply the chemical liquid through the rotary joint.

Therefore, the rotary drum 21 is rotated and the cap C engaged with the engagement groove 23 is rotated by the spiral guide 22.
When the spiral cleaning path portion 20 is guided to and is moved upward along the spiral transport path 20, first, in the preliminary cleaning path portion 20a, the chemical liquid after cleaning of the main cleaning path portion 20b is flown into the mouth portion of the cap C for preliminary cleaning, Next, the chemical liquid is sprayed onto the cap C from the plurality of spray nozzles 42A to 42C in the main cleaning path portion 20b. Then, the drug solution is stored in the mouth of the upward cap C, the inner surface is dipped in the drug solution, and the outer surface is also dipped in the drug solution to be sprayed, so that the drug solution is sterilized well and uniformly. Further, as the cap C is rotated by the frictional force of the side wall portion 22b along with the swirling movement, and the rotation movement is further promoted by the chemical liquid injected from the side outer surface injection nozzle 42A, the chemical liquid accumulated in the mouth is fluidized. The bubbles that are agitated and adhered to the inner surface are effectively separated and removed, whereby the inner surface can be uniformly sterilized and sterilized.
