DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water remover for removing (drying) water such as water droplets attached to an outer surface by blowing off the liquid by air injection.

[0002]

2. Description of the Related Art For example, in a place such as a food processing plant or a food store where food is packed in a packaging bag or wrapped with a wrap film, the food adheres to the outer surface of the packaging bag or the surface of the wrap film. In order to remove water droplets, since the contents are food and cannot be dried by heating, most of them are actually wiped off by hand. In some cases, a water removal machine that blows off water droplets by air injection is used, but in the conventional water removal machine, the air nozzle that injects air is simply a straight pipe or flat shape, so one air nozzle is used. Since the injection area per contact is narrow and the interval between the air nozzles must be close, not only the number of air nozzles increases but also the amount of air supplied from the air supply source needs to be large, resulting in poor efficiency.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is not only to increase the spraying area per air nozzle but also to improve the water removal effect and to reduce the number of air nozzles as compared with the prior art. In addition, an object of the present invention is to provide a water remover that can save the amount of air, is highly efficient, can easily cope with a change in the size of the object to be processed, and can easily perform inspection and cleaning.

[0004]

SUMMARY OF THE INVENTION A water remover according to the present invention comprises:
A box-like cover that covers a part of the mesh-like conveyor from above is attached to the machine-frame on which the mesh-like conveyor is mounted so that it can be opened and closed. That the upper air box is mounted on the box cover so that it can be raised and lowered, and that the upper air box is mounted on the box cover with a handle for raising and lowering the box from outside the box cover.
A flat box-shaped lower air box is installed below the mesh conveyor, and some or all of the plurality of air nozzles are connected to the upper and lower air boxes so that they can pivot freely on the outer surface of the air box. In addition to being installed and supported, the injection port is obliquely directed as a shape that curves with respect to its axis.

[0005]

According to the water remover of the present invention, when air is supplied from an air supply source into upper and lower air boxes, air is simultaneously injected from air nozzles projecting from these air boxes. The air nozzle is curved and its injection port is directed obliquely, and is freely rotatable with respect to the air box. Therefore, the air nozzle automatically turns by the reaction force of the air jetted from the injection port. Therefore, the air jetted from each air nozzle above and below the mesh conveyor spreads spirally from both the top and bottom toward the workpiece conveyed on the mesh conveyor, and is blown so as to generate vibration over a wide area. The upper air box is mounted on an openable and closable box cover that covers a part of the mesh conveyor.Opening this box cover opens the entire upper surface of the mesh conveyor and protrudes from the upper air box. Air nozzle can be turned upward. By operating the handle to raise and lower the upper air box outside the box-shaped cover, the height of the upper air nozzle can be adjusted to cope with a change in the size of the object to be processed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings.

As shown in FIGS. 1 and 2, the water removal machine of this embodiment has a single structure in which the entire body is incorporated into a machine frame 1, and a mesh conveyor 2 mounted on the machine frame 1. An object to be processed W (shown in FIG. 3) is placed thereon and transported (conveyed from the near side to the rear in FIG. 1), and an upper air jet unit 3 provided on the machine frame 1 in the middle of the conveyor 2 3 and 4, opposed to this, a lower air injection unit 4 provided in the machine frame 1 injects air from both upper and lower sides to remove water.

The mesh conveyor 2 has a wire mesh 6 and a number of support rods 7 stretched between left and right chains 5, and the left and right chains 5 are meshed by a sprocket wheel 8 rotated by a motor (not shown). 6 and is circulated integrally.

The upper air injection unit 3 has a box-shaped cover 9 hinged to the machine frame 1 so as to open and close so as to cover a part of the net-shaped conveyor 2, and has the following structure incorporated therein. It is. 3 to 5,
A plurality of guide rods 11 are suspended from a top plate 10 of the box-shaped cover 9, and a lift base plate 12 is mounted on these guide rods 11 so as to be able to move up and down. Flat box-shaped air boxes 13A and 13B are fixed in parallel to the front and rear lower two portions of the elevating base plate 12, and a hose 14 is provided in the air boxes 13A and 13B from an air supply source (not shown) such as a blower. The air is sent through. A plurality of short pipe-shaped swirling air nozzles 15 are provided on the front side of the air box 13A (on the front side with respect to the transport direction of the mesh conveyor 2) at a predetermined interval on the left and right, and are arranged in a row. In the air box 13B on the side, a plurality of swirling air nozzles 15 are protruded in a line at a fixed interval on the left and right, and a plurality of fixed air nozzles also having a short pipe shape are provided behind the line. 16 are provided in a row at a predetermined interval on the left and right.

The swiveling air nozzle 15 of the front (front) air box 13A and the rear air box 13B
Although the left and right intervals are the same as those of the swirling type air nozzle 15, the number of the front side is four and the number of the rear side is three in the example of the figure, and the mutual positional relationship is different from side to side. The interval between the fixed air nozzles 16 is smaller than that of the swirling air nozzles 15 and is dense.

As shown in the rear side of FIG. 6, each of the revolving air nozzles 15 of the front and rear air boxes 13A and 13B has a base end (upper end) penetrated and fixed to the bottom wall of the air box. It is pivotally supported by a bearing bolt 17 via a bearing 18 and communicates with the inside of the air box through the bearing bolt 17. Swirling air nozzle 15
The upper portion 15a is vertical, the middle portion 15b is gently curved in the X direction, which is a direction orthogonal to the axis of the bearing bolt 17, and the lower portion 15c is gently curved in the Y direction, which is orthogonal to the X direction. The injection port 19 at the tip is directed obliquely downward.

Each fixed type air nozzle 16 has its upper end threaded through the air box 13B and is connected to the inside of the air box 13B. The lower side portion 16a of the fixed air nozzle 16 is gradually flattened toward the lower end, and is inclined forward (to the front side with respect to the transport direction of the mesh conveyor 2) while being crushed flat, so that the injection port 20 at the lower end becomes flat. It is directed obliquely downward and forward.

The elevating base plate 12 can be moved up and down along the guide rod 11 by turning a handle 21 mounted on the outside of the ceiling of the box-shaped cover 9.・ 16 can adjust its height. On the front and rear walls of the box-shaped cover 9, as shown in FIG. 4, cutout portions 22 for allowing the workpiece W on the mesh conveyor 2 to pass therethrough are provided, and each cutout portion 22 is cut into a resin sheet or the like. A curtain 23 is provided vertically. The box-shaped cover 9 is provided with a viewing window 24 made of a transparent plate.

On the other hand, the lower air injection unit 4 is provided with one air box 25 fixedly arranged in the machine frame 1 and a front row of swirling air nozzles 15, a rear row of swirling air nozzles 15 and a fixed air nozzle 16. Are projected upward in the same manner as the upper air injection unit 3 and face the air nozzles 15 and 16 on the upper air injection unit 3 side in a one-to-one relationship. The upper and lower air boxes 1
3a and 13B may be one like the lower air box 25. On the contrary, the lower air box 2
5 may be divided into two similarly to the upper side. A water recovery unit (not shown) is provided below the lower air injection unit 4.

The air boxes 13A and 13B before and after the upper air injection unit 3 and the lower air injection unit 4
Since air is simultaneously supplied from an air supply source to the air box 25, air is supplied from the swirling air nozzles 15 in the front row, the swirling air nozzles 15 in the rear row, and the fixed air nozzle 16 in the upper air injection unit 3. Simultaneously with the downward jetting, air is jetted upward from the swirling air nozzles 15 in the front row, the swirling air nozzles 15 in the rear row, and the fixed air nozzle 16 of the lower air jet unit 4.

Therefore, the workpiece W conveyed on the mesh conveyor 2 is blown with air from both the upper and lower sides when passing through the inside of the box-shaped cover 9, and the attached water droplets and the like are blown off over the entire surface. In this case, since the upper and lower air nozzles face each other in a one-to-one relationship, the workpiece W conveyed on the mesh conveyor 2 floats or the mesh conveyor 2
There is no such thing as being pushed hard.

Each swirling air nozzle 15 is rotatable with respect to the air box 13A or 13b or 25, and is curved as described above to form its injection port 19.
Are directed obliquely, so that when air is ejected from the injection port 19, a moment is generated by the reaction force, and the air is automatically turned. Therefore, the air injected from each of the swirling air nozzles 15 spirally spreads toward the workpiece W conveyed on the mesh conveyor 2 and is blown so as to generate vibrations over a wide range, so that the workpiece is blown. The water removal effect on W is very high. In the upper and lower air jet units 3 and 4, the front row swirling air nozzles 15 and the rear row swirling air nozzles 15 are staggered left and right as described above. Even if it is widened, no unprocessed portion is generated, and by making the interval wide, it is possible to prevent air interference between adjacent swirling air nozzles 15.

The air from the upper and lower fixed air nozzles 16 is sprayed obliquely forward so as to form a so-called air curtain and convey the workpiece W, so that the water droplets blown off by the swirling air nozzles 15 Can be prevented from adhering again to the workpiece W coming out of the box-shaped cover 9. Air nozzle 15.1 of upper air injection unit 3
The height of 6 can be adjusted according to the size of the workpiece W by operating the handle 21. Note that the height of the lower air nozzles 15 and 16 may also be adjustable.

[0019]

As described above, according to the present invention, the following effects can be obtained. A plurality of air nozzles are supported by a common air box so as to be pivotable, and the injection ports are directed obliquely in a curved shape. Each air nozzle is automatically rotated by the reaction force generated by air injection. Spray air from the nozzles can be blown in a spiral manner from both the upper and lower sides toward the workpiece conveyed on the mesh conveyor so as to generate vibration over a wide area. Therefore, not only can the spray area per air nozzle be widened, but also the water removal effect is good, and the number of air nozzles can be reduced, and a highly efficient water removal machine capable of saving the amount of air can be provided. it can.

Since the upper air box is mounted on an openable and closable box cover that covers a part of the mesh conveyor, opening this box cover allows the entire upper surface of the mesh conveyor to be opened and the upper air box to be open. Inspection and cleaning are easy because the air nozzle protruding from the nozzle can be turned upward.

By operating a handle to raise and lower the upper air box outside the box-shaped cover,
By adjusting the height of the upper air nozzle, it is possible to easily respond to changes in the size of the workpiece.
