[0004] This does not pose a problem if the object to be dewatered is relatively heavy. However, when the object to be dewatered is light, there is a problem that the object to be dewatered may be detached from the conveyor due to the air jet from the nozzle pipe.

[0005] An object of the present invention is to provide a water removal machine and a water removal method that have been made in consideration of the above problems. [Means for solving the problem]

[0019] A water remover and a water removal method according to one embodiment of the present invention will be described with reference to Figs.

[0020] Z shown in Figure 1 is a water remover, which is equipped with a first water-permeable conveyor 1 for transporting the object 10 to be removed, and an endless chain 2 that abuts against the upper surface 10X of the object 10 to be removed on this first water-permeable conveyor 1.

[0021] The object 10 to be dewatered is a standing pouch having a gusset on the bottom surface 10Y. When the first water-permeable conveyor [the first water-permeable conveyor is, for example, a plastic belt made of resin, more specifically, a belt having a high friction coefficient (a plastic belt with a rubber surface)] 1 moves from right to left (or left to right), the bottom surface 10Y of the water-removal target 10 is located in front, and the water-removal target 10 on the first water-permeable conveyor 1 is transported by the first water-permeable conveyor 1 in a state where the endless chain 2 is in contact with the top surface 10X of the water-removal target 10 on the first water-permeable conveyor 10, and the water adhering to the bottom surface 10Y of the water-removal target 10 is scattered by air injection from the first nozzle 3 located outside the water-removal target 10, thereby removing the water. The endless chain 2 is an endless chain in which link plates are endlessly connected by pins and hung between the first and second sprockets 21, 22. For example, the endless chain 2 may be a single chain, but preferably multiple chains (for example, three chains) are provided. In addition, the moving direction of the first conveyor 1 located on the underside of the object 10 to be dewatered and the moving direction and speed of the single or multiple endless chains 2 located on the upper surface 10X of the object 10 to be dewatered are the same.

[0022] According to the above-mentioned water removal machine Z (water removal method), an endless chain 2 is abutted against the upper surface 10X of the light-weight object to be water removed 1 on the first water-permeable conveyor 1, i.e., the weight of the endless chain 2 prevents the object to be water removed 10 from moving on the first water-permeable conveyor 1, and air is sprayed from a first nozzle 3 positioned outside the object to be water removed 10 to scatter the water adhering to the bottom surface 10Y of the object to be water removed, thereby removing the water. In addition, with multiple (e.g., three) endless chains 2 abutting the upper surface 10X of the object to be dewatered 1 on the first water-permeable conveyor 1, that is, with the weight of the multiple endless chains 2 preventing the object to be dewatered 1 on the first water-permeable conveyor 1 from moving, the water in the object to be dewatered 1 can be scattered by air spraying from a first nozzle 3 positioned outside the object to be dewatered 10, thereby removing the water.

[0023] Further, 4 denotes a pair of second water-permeable conveyors (made of, for example, wire mesh) that sandwich and transport the upper surface 10X and the lower surface of the object 10 to be dewatered. The pair of second water-permeable conveyors 4 is located in front of the first water-permeable conveyor 1 . A second nozzle 5 is located above the pair of second water-permeable conveyors 4, and a third nozzle 6 is located below the pair of second water-permeable conveyors 4, respectively. The water adhering to the lower surface 10Z of the object 10 to be dewatered is scattered by air sprayed from the second nozzle 5, and the water adhering to the upper surface 10X of the object 10 to be dewatered is scattered by air sprayed from the third nozzle 6, thereby removing the water. In addition, 30 is a first fan which is the source of air jet from the first nozzle 3, 50 is a second fan which is the source of air jet from the second nozzle 5, and 60 is a third fan which is the source of air jet from the third nozzle 6.

[0024] In the above-described embodiment, the pair of second water-permeable conveyors 4 are positioned in front of the first water-permeable conveyor 1, but the present invention is not limited to this, and although not shown, the pair of second water-permeable conveyors 4 may be positioned behind the first water-permeable conveyor 1. In addition, S shown in Figure 1 is a supply conveyor that supplies the object to be dewatered 10 to the first conveyor 1, and 31 is a passage that transmits air from the first blower 30 to the first nozzle 3, and the passage that transmits air from the second blower 50 to the second nozzle 5 and the passage that transmits air from the third blower 60 to the third nozzle 6 are not shown.
