[Problems to be solved by the invention]
By the way, in recent years, standing pouches that are self-supporting while containing a fluid substance such as liquid or powder have been increasingly used as packaging containers. The bottom of the standing pouch is foldable, and the bottom expands in a self-standing state, but when folded down, the standing pouch is folded due to the fluidity of the stored contents.
[0005]
To remove water from such a standing pouch, if it is placed on a conveyor and transported sideways, the front and back surfaces (upper and lower surfaces) of the body of the standing pouch can be removed by the upper and lower air jet units. Since the bottom is in a folded state, water cannot be removed by the horizontal air injection unit.
[0006]
Therefore, an object of the present invention is to provide a water remover that can also remove water at the bottom of a standing pouch.
[0007]
[Means for Solving the Problems]
The water removal machine of the present invention is a presser which presses a standing pouch, which is a water removal target conveyed sideways on a conveyor, from above and expands a bottom portion thereof at a position opposed to a nozzle of a horizontal air injection unit. A unit is provided.
[0008]
The holding unit preferably has a holding roller rotatably supported by a roller holder vertically attached to the upper air injection unit.Also, a plurality of holding rollers are attached to the roller holder at intervals in the conveyor conveyance direction. What is supported is better.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, embodiments of the present invention will be described in detail with reference to the drawings.
[0010]
In this water remover, as shown in FIG. 1, a lower air injection unit 2 is fixedly installed on a main body housing 1, and an upper air injection unit 3 is opened and closed on the lower air injection unit 2 vertically. I am wearing it.
[0011]
As shown in FIG. 2, the lower air injection unit 2 has a lower air box 5 detachably installed between an upper part 4 a and a lower part 4 b of the mesh conveyor 4. A large number of spin nozzles 6 are individually pivotally mounted facing upward.
[0012]
The upper air injection unit 3 has an upper air box 9 detachably mounted below a mounting plate 8 whose height can be adjusted by a height adjustment handle 7. The nozzles 10 are individually mounted so as to be pivotable with the nozzles 10 facing downward, and a horizontal air jet unit 11 is provided vertically. The horizontal air jet unit 11 vertically hangs a plurality of bottomed cylinders 12 on the lower surface of the upper air box 9 apart from each other in the conveying direction of the conveyor 4, and can turn the spinned nozzles 13 in each bottomed cylinder 12 sideways. It is attached to.
[0013]
Air is supplied to the lower air box 5 and the upper air box 9 from a blower (not shown) installed in the main body housing 1, and a large number of spin nozzles 6 of the lower air injection unit 2 The air is jetted upward from below while turning on the object to be removed, and the multiple spin nozzles 10 of the upper air injection unit 3 are rotated upward on the object to be removed on the conveyor 4 while turning. , And the plurality of spin nozzles 13 of the horizontal 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 portion 50a expanded, but in order to remove water, the standing pouch 50 is laid down on the conveyor 4 as shown in FIG. If the contents are transported in a folded state, the stored contents will be folded due to the fluidity of the contents. Therefore, the air from the spin nozzle 13 of the horizontal air injection unit 11 cannot be jetted to the bottom 50 a of the standing pouch 50, and the front and back surfaces (upper and lower surfaces) of the body of the standing pouch 50 have a large number of upper air injection units 3. Although the water can be sufficiently removed by the spin nozzles 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]
Therefore, in this water remover, as shown in FIG. 2, the holding unit 14 that presses the standing pouch 50 conveyed in a state of being laid down on the conveyor 4 from the upper side is suspended from the upper air box 9. FIGS. 4 and 5 show the holding unit 14.
[0016]
The holding unit 14 is configured such that a plurality of (three in the figure) holding rollers 16 are rotatably rotated by bolts and nuts on a roller holder 15, which is a long plate long in the conveying direction of the conveyor 4, separated in the conveying direction of the conveyor 4. The roller holder 15 is pivotally supported, and is mounted on a pair of L-shaped brackets 17 vertically attached to the lower surface of the upper air box 9 so as to be adjustable in height.
[0017]
The holding unit 14 configured as described above is provided near the center of the conveyor 4 with respect to the horizontal air injection unit 11 and opposed thereto, and therefore, as shown in FIGS. The plurality of holding rollers 16 press the body of the standing pouch 50 conveyed sideways from above while rotating. Since the content in the standing pouch 50 is a fluid substance, the bottom 50 a of the standing pouch 50 is spread by the pressure of the fluid substance at a position facing the spin nozzle 13 of the horizontal air jet unit 11 and is ejected from the spin nozzle 13. Since air is received over the entire bottom surface, water removal from the bottom portion 50a is sufficiently performed.
[0018]
Note that, instead of the pressing roller 16, a sled-shaped or rod-shaped pressing member that is long in the transport 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 sideways on the conveyor is pressed from the upper side and the bottom portion is expanded at a position opposed to the nozzle of the horizontal air injection unit, the standing pouch is formed. The water can be removed not only from the front and back sides of the body, but also from the bottom.
