  Next, the operation of the present embodiment having the above-described configuration will be described.

  FIG. 12 is an explanatory view schematically showing an operation example for removing the liquid adhering to the surface of the package by the package liquid removing apparatus according to the present invention.

  The removal of the liquid E adhering to the surface of the package P by the package liquid removing apparatus 1 of the present embodiment starts with the drive motor 5 driven. Then, by driving the drive motor 5, both the transport body 24 of the carry-in conveyor 23 disposed in the supply unit 18 and the transport body 24 of the intermediate transport conveyor 34 disposed in the intermediate transport unit 20 are shown in FIG. It is driven to rotate clockwise. In the first liquid removing unit 19 and the second liquid removing unit 21, both the upper liquid suction holding roller 26 is driven to rotate counterclockwise in FIG. 1, and the lower liquid suction holding roller 26 is both shown in FIG. While rotating clockwise, the inside of the squeeze suction pipe 32 is held in a reduced pressure state. In addition, each pipe body 38 disposed in the intermediate transport unit 20 is rotated, the tip of each injection nozzle 37 swings about the pipe body 38, and air is supplied to each pipe body 38, and each injection Air is jetted from the tip of the nozzle 37.

  In such a state, the package P to be used for removing the liquid E, for example, the package P1 shown in FIG. 6, is supplied to the carry-in conveyor 23 with the bottom PC1a of the package container PC1 as the leading side in the transport direction. Then, as shown in FIG. 12, the package P1 supplied to the carry-in conveyor 23 is conveyed toward the first liquid removing unit 19 by the carry-in conveyor 23 with the bottom PC1a at the top.

  Subsequently, the package P that has reached the first liquid removing unit 19 by the conveyance of the carry-in conveyor 23 is sandwiched between the pair of upper and lower liquid suction holding rollers 26 at the leading side in the conveyance direction, and is intermediately conveyed by the rotation of each liquid suction holding roller 26. It is conveyed toward the section 20.

  At this time, the surface of the packaging body P comes into contact with the surface of the suction holding body 28 of each liquid suction holding roller 26, so that the liquid E adhering to the surface of the packaging body P is absorbed by the suction holding body of each liquid suction holding roller 26. 28 is aspirated. The liquid E sucked by the suction holding body 28 is held inside the suction holding body 28.

  Further, when the packaging body P passes between the liquid suction and holding rollers 26, the suction holding body 28 is easily elastically deformed following the shape of the packaging body P, so that the passage of the packaging body P is made smooth. be able to. At this time, since the suction holding body 28 is divided along the axial direction, each portion of the suction holding body 28 is elastically deformed individually, so that the surface of the suction holding body 28 is in the transport direction of the package P. And elastically deforms following the shape in the orthogonal direction. That is, since the suction holder 28 is easily elastically deformed following the shape of the package P, the surface of the suction holder 28 can be reliably brought into contact with the surface of the package P1. Furthermore, since the suction holding body 28 is easily elastically deformed following the shape of the package P, the force applied to the surface of the package P1 can be made substantially uniform in the direction orthogonal to the transport direction.

  In addition, when the suction holding body 28 is formed integrally with the rotary shaft 27, the whole is integrally elastically deformed. Therefore, depending on the shape of the packaging body P or the type of contents, the suction holding body 28 and the packaging body There is a high risk that a gap will be formed between P and P.

  Further, the liquid E sucked and held by each suction holding body 28 is squeezed out by the squeezing roller 31 in the upper liquid suction holding roller 26. The squeezed out liquid E is sucked by the squeezed suction pipe 32 and is discharged through a liquid receiving member 17 to a storage tank (not shown) disposed below the liquid receiving member 17 or to the outside. Further, the lower liquid suction holding roller 26 is squeezed by the squeezing roller 31 and flows down to the liquid receiving member 17, and is discharged to a storage tank (not shown) disposed below the liquid receiving member 17 or to the outside. .

  Therefore, the liquid suction / holding roller 26 is not in a wet state, and can always maintain a state in which the liquid E is not held.

  Next, the package P that is sandwiched and transported between the pair of upper and lower liquid suction / holding rollers 26 of the first liquid removing unit 19 is transferred to the intermediate transport conveyor 34 of the intermediate transport unit 20.

  At this time, since the pair of upper and lower jet nozzles 37 are provided in the packaging body liquid removing apparatus 1 of the present embodiment, the air jetted from the tip of the pair of upper and lower jet nozzles 37 is the first liquid. It is sprayed against the package P immediately after passing through the pair of upper and lower liquid suction holding rollers 26 of the removing unit 19.
