[0002]
[Prior art]
As described in Patent Document 1 (Patent No. 2949662), the applicant of this type of water removal machine has a conveyor and a water removal object conveyed on the conveyor from a number of nozzles. An upper air injection unit that injects air downward, a lower air injection unit that injects air upward from a number of nozzles onto the water removal target to be transported, and air from the nozzles to the water removal target to be transported sideways Have already been provided with a sideways air injection unit that injects air.

[Problems to be solved by the invention]
By the way, in recent years, as a packaging container, a standing pouch that is self-supporting in a state in which a fluid substance such as a liquid or a powder is accommodated is increasing. The standing pouch has a bottom that can be folded, and the bottom expands in a self-supporting state, but when it is laid down, it becomes folded due to the fluidity of the contained contents.
[0005]
In order to remove the standing pouch with such properties, it can be removed by the upper and lower air jet units on both the upper and lower surfaces (upper and lower surfaces) of the trunk portion of the standing pouch when transported while lying on the conveyor. Since the bottom is in a folded state, water cannot be removed by the sideways air jet unit.
[0006]
Therefore, an object of the present invention is to provide a water removal machine that can also remove water from the bottom of a standing pouch.
[0007]
[Means for Solving the Problems]
The dewatering machine of the present invention is a presser that presses a standing pouch, which is a dewatering object to be transported on a conveyor in a sideways state, from the upper side so that the bottom part of the standing pouch faces the nozzle of the sideways air injection unit. A unit is provided.
[0008]
The holding unit is preferably a roller holder that is suspended from the upper air jet unit, and the pressing roller is rotatably supported by the roller unit. Also, a plurality of pressing rollers are attached to the roller holder at intervals in the conveying direction of the conveyor. What you support is even better.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described in detail with reference to the drawings.
[0010]
As shown in FIG. 1, the dewatering machine has a lower air injection unit 2 fixedly installed on a main body housing 1 and an upper air injection unit 3 that can be opened and closed freely on the lower air injection unit 2. Wearing.
[0011]
As shown in FIG. 2, the lower air injection unit 2 detachably installs a lower air box 5 between the upper part 4 a and the lower part 4 b of the mesh conveyor 4, and on the upper surface of the lower air box 5, A large number of spin nozzles 6 are turned upward and are individually pivotably mounted.
[0012]
The upper air injection unit 3 has an upper air box 9 detachably attached to the lower side of a construction plate 8 whose height can be adjusted by a height adjustment handle 7. The nozzles 10 are faced downward and are individually pivotably mounted, and a sideways air injection unit 11 is provided vertically. The sideways air injection unit 11 hangs a plurality of bottomed cylinders 12 on the lower surface of the upper air box 9 apart in the transport direction of the conveyor 4, and can rotate with the spin nozzle 13 sideways on each bottomed cylinder 12. It is attached to.
[0013]
Air is supplied to a lower air box 5 and an upper air box 9 from a blower (not shown) installed in the main body housing 1, and a number of spin nozzles 6 of the lower air injection unit 2 are arranged on the conveyor 4. The air is jetted upward from below while turning to the water removal target being transported, and a number of spin nozzles 10 of the upper air jet unit 3 are swung upward to the water removal target being transported on the conveyor 4 The plurality of spin nozzles 13 of the sideways air injection unit 11 inject air from the side while turning to the water removal target conveyed on the conveyor 4.
[0014]
By the way, as shown in FIG. 6, the standing pouch 50 is self-supporting with the foldable bottom 50a being expanded, but in order to remove water, the standing pouch 50 is laid on the conveyor 4 as shown in FIG. When it is transported with a container, it will be in a folded state due to the fluidity of the contained contents. Therefore, the air from the spin nozzle 13 of the sideways air injection unit 11 cannot be injected to the bottom 50 a of the standing pouch 50, and the front and back both surfaces (upper and lower surfaces) of the trunk portion of the standing pouch 50 are many of the upper air injection unit 3. Although the water can be sufficiently removed by the spin nozzle 10 and the multiple spin nozzles 6 of the lower air injection unit 2, the bottom 50a cannot be removed or the water removal is insufficient.
[0015]
In view of this, in this dewatering machine, as shown in FIG. 2, a pressing unit 14 that presses the standing pouch 50 conveyed on the conveyor 4 in a sideways state is suspended from the upper air box 9. 4 and 5 show the pressing unit 14.
[0016]
The holding unit 14 has a plurality of (three in the figure) holding rollers 16 separated in the conveying direction of the conveyor 4 and can be freely rotated by bolts and nuts on a roller holder 15 that is a long plate in the conveying direction of the conveyor 4. The roller holder 15 is pivotally supported, and is installed on a pair of L-shaped brackets 17 vertically attached to the lower surface of the upper air box 9 so that the height can be adjusted.
[0017]
Since the holding unit 14 configured in this manner is provided at a position facing the lateral air jet unit 11 near the center of the conveyor 4, as shown in FIG. 2 and FIG. The body portion of the standing pouch 50 conveyed in a sideways state is pressed from above while the plurality of pressing rollers 16 rotate. Since the content in the standing pouch 50 is a fluid substance, the bottom 50a of the standing pouch 50 is expanded by the pressure of the fluid substance at a position facing the spin nozzle 13 of the sideways air injection unit 11, and is ejected from the spin nozzle 13. Since air is received over the entire bottom, water removal from the bottom 50a is sufficiently performed.
[0018]
Instead of the pressing roller 16, a hook-shaped or rod-shaped pressing member that is long in the conveying direction of the conveyor 4 may be used.
[0019]
【The invention's effect】
As described above, according to the present invention, since the standing pouch conveyed on the conveyor in a sideways state is pressed from the upper side so that the bottom portion of the standing pouch faces the nozzle of the sideways air injection unit, the standing pouch Water removal at the bottom as well as the front and back sides of the torso can be performed sufficiently.
