The plurality of nozzles comprises turning nozzles 22, 25, 26 whose air jetting port turns with reaction of jetting air, and stationary nozzles 23, 27, 28 whose air jetting port is fixed, wherein the turning nozzles and the stationary nozzles are aligned in a conveyance direction of a conveyance band.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a dewatering or dust removing machine that blows away water droplets adhering to a food container after washing, or dust adhering to parts or the like in a manufacturing process.

As this type of water remover, the one described in Patent Document 1 is conventionally known, and FIGS. 7 and 8 attached to the present application show this conventional water remover.
In the conventional water removal machine, a chain conveyor 2 is provided on a base 1, and the food pouch 3 shown in FIG. .

  Further, a first injection unit A shown in FIG. 8 is provided on the base 1 below the chain conveyor 2. The first injection unit A is composed of a plurality of lower swirl nozzles 4. Each of the lower swirl nozzles 4 constituting the first injection unit A is configured such that its jet port swirls by the reaction force of the compressed air ejected therefrom.

  Further, a second injection unit B is provided on the upper side of the base 1, and an air box 5 is incorporated in the second injection unit B, and the second injection unit B straddles the chain conveyor 2. Alternatively, the chain conveyor 2 can be freely rotated within a range of opening.

The air box 5 as described above is provided with an upper turning nozzle 6 for jetting compressed air toward the chain conveyor 2 and a side turning nozzle 7 whose turning axis is substantially horizontal to the chain conveyor 2. Each of the swirling nozzles 6 and 7 is configured to swivel its outlets by the reaction force of the compressed air ejected from the same as the lower swirling nozzle 4.
Each of the swivel nozzles 4, 6, and 7 is connected to a common pneumatic pressure source (not shown).

  In addition, the code | symbols 8 and 9 in a figure are a pair of guide provided in the conveyance direction of the said chain conveyor 2. As shown in FIG. Of these two guides 8 and 9, one guide 8 is in contact with the bottom of the food pouch 3 as shown in FIG. 8, and the other guide 9 is in the thin part on the mouth side of the food pouch 3. In contact, the position and posture of the food pouch 3 are not disturbed by the wind pressure of the swivel nozzles 4, 6 and 7.

And since the said one guide 8 contacts the bottom part of the food pouch 3 with a whole width, a round bar is sufficient. However, the other guide 9 is in contact with a thin portion on the lid side of the food pouch 3, and therefore a plate that is erected substantially perpendicular to the chain conveyor 2 is used.

  Further, reference numerals 10 and 11 in the figure are a presser unit provided on the ceiling portion of the first injection unit A, and a pair of presser rollers arranged in the transport direction of the chain conveyor 2. The individual rollers constituting the presser roller groups 10 and 11 are configured to exert a force in the direction of pressing the food pouch 3 by the action of the elastic force of the leaf springs 12 and 13.

  In this way, by pressing the food pouch 3 on the chain conveyor 2 from above with the presser roller groups 10 and 11, the food pouch 3 is held in four directions by the pair of guides 8 and 9 and the presser roller groups 10 and 11. Therefore, the posture of the food pouch 3 is hardly disturbed by the wind pressure of the swivel nozzles 4, 6, 7, or the impact.

The reason why the food pouch 3 is firmly pressed so as not to disturb the posture of the food pouch 3 being conveyed as described above is to prevent the relative position of the food pouch 3 and the swivel nozzles 4, 6 and 7 from being disturbed. . If the relative position between the food pouch 3 and the swirl nozzles 4, 6, 7 shifts, the compressed air ejected from the swirl nozzles 4, 6, 7 will not hit the target location.
In order to prevent such a situation, the posture of the food pouch 3 being conveyed is not disturbed.

The presser roller group 10 on the side close to the bottom of the food pouch 3 also has a function of opening the bottom of the food pouch 3.
The bottom portion of the food pouch 3 has a depth when viewed from the outside, so that when the bottom portion is conveyed in a crushed state, the compressed air from the side swirl nozzle 7 does not hit the bottom portion, and water can be removed. Disappear.
For this purpose, the bottom side of the food pouch 3 is pressed by the press roller group 10 to open the side surface of the bottom.

Japanese Patent No. 4288899

  In the conventional water remover as described above, only the swirl nozzles 4, 6, 7 are used, and water droplets are blown off by the jet output of the compressed air from the nozzles 4, 6, 7. The swirl nozzles 4, 6, and 7 are suitable for applying compressed air to a wide range of their swivel range, but can hardly apply compressed air to a limited narrow range.

For this reason, for example, the bottom of the food pouch 3 and the corner portion formed by the container main body and the flange on the lid side such as a yogurt container are not exposed to compressed air, and the water cannot be removed. There was a problem.
In the above description, the water remover is a conventional example, but the dust remover has the same problem.

  An object of the present invention is to provide a water removal or dust remover that can reliably remove water or remove dust entirely while applying compressed air to a limited narrow range.

  1st invention provides a some nozzle along a conveyance belt | band | zone, blows air with respect to the process target object conveyed on a conveyance belt | band | zone, and removes the water droplet and dust which the said process target object has adhered. The present invention relates to a water removal or dust remover, and the plurality of nozzles includes a turning nozzle and a fixed nozzle.

  The revolving nozzle is revolved by the reaction force of the ejected air, and the air ejection port revolves. Accordingly, the compressed air hits the surface to be subjected to the water removal or dust removal treatment corresponding to the swirl range of the jet outlet. In addition, the swirl nozzle performs a function of intermittently striking the processing target surface with compressed air in accordance with the swirling speed, so that water droplets and dust adhering to the processing target surface rise from the processing target surface. It also functions.

On the other hand, since the fixed nozzle has a fixed jet outlet, the compressed air can be concentrated at a specific location to which the jet nozzle is directed.
Therefore, when there are dents or corners where the surfaces intersect each other in the surface to be processed, the water droplets and dust in that portion can be discharged with compressed air.

When water droplets and dust are dispensed from the dents and corners as described above, they can be blown off by the swivel nozzle. In particular, since the swirl nozzle can spray compressed air over a wide range of the swirl range of the jet outlet as described above, it is possible to reliably blow off water droplets and dust discharged by the fixed nozzle.
That is, water droplets and dust on the processing target surface can be surely removed while the swirling nozzle and the fixed nozzle act synergistically.

In the second invention, the swivel nozzle and the fixed nozzle are connected to a pipe having an angle adjusting function such as a coolant hose.
Therefore, these swirl nozzles and fixed nozzles can freely set the swirl range and jet direction of the compressed air by adjusting the angle of the pipe.

  In the third aspect of the invention, since the fixed nozzle is a straight pipe that linearly guides the compressed air, the directivity of the compressed air ejected from the fixed nozzle can be improved.

  In a fourth aspect of the invention, the fixed nozzle is an air knife provided with an opening in the width direction of the processing object. Therefore, when the surface to be dewatered or dedusted is, for example, a long object with a certain width, a fixed nozzle consisting of an air knife collects the water droplets and debris, and then removes the water droplets and debris from the swivel nozzle. If it is wiped off, water removal or dust removal can be reliably carried out even for wide and long objects.

  According to the water removal or dust removal machine of the present invention, the swirling nozzle and the fixed nozzle can act synergistically to reliably remove water droplets and dust on the surface to be treated.

FIG. 1 is an explanatory view showing the relationship between a food pouch conveyed by a chain conveyor and a water removal machine. FIG. 2 is a perspective view of a food pouch. FIG. 3 is a view showing the relative positional relationship between the bottom of the food pouch and the nozzle. FIG. 4 is an explanatory diagram of the second embodiment. FIG. 5 is an explanatory diagram of the third embodiment. FIG. 6 is an explanatory diagram of the fourth embodiment. FIG. 7 is a perspective view of a conventional water remover. FIG. 8 is an explanatory view showing the relationship between a pouch for food conveyed by a conventional chain conveyor and a water removal machine.

  The first embodiment shown in FIGS. 1 to 3 is different from the conventional example shown in FIGS. 7 and 8 in that the type and arrangement of each nozzle and the press roller that opens the bottom of the food pouch P are provided. The rest of the configuration is the same as that of the conventional example. Therefore, the same components as those in the prior art will be described using the same reference numerals as those in FIGS.

The base 1 described with reference to FIG. 7 is provided with a chain conveyor 2 which is a transport band of the present invention, and a first injection unit U1 is provided below the chain conveyor 2.
In the first injection unit U1, an air box 21 is provided, and a plurality of lower swivel nozzles 22 and a plurality of lower fixed nozzles 23 are provided in the air box 21.

The transport belt of the present invention does not need to be a chain conveyor, and in particular, if the compressed air ejected from the lower swivel nozzle 22 or the lower fixed nozzle 23 can be blown upward from the transport belt, Something like that.
Further, depending on the object to be processed, the lower turning nozzle 22 and the lower fixed nozzle 23 may not be required. In such a case, the transport belt only needs to have a function of transporting the processing object.

The lower swivel nozzle 22 and the lower fixed nozzle 23 are alternately arranged in the conveying direction of the chain conveyor 2 as shown in FIG.
The lower swirl nozzle 22 has a structure in which the jet outlet swirls by the reaction force of the compressed air ejected from the lower swirl nozzle 22 as well as the conventional swirl nozzle, and the swivel shaft serves as the transport surface of the chain conveyor 2. And almost orthogonal.

  The compressed air ejected from the lower swirl nozzle 22 thus made passes through the chain conveyor 2 and is ejected upward. Therefore, the compressed air ejected from the lower swirl nozzle 22 hits the lower surface of the food pouch P, which is a processing object that is carried on the chain conveyor 2.

The lower fixed nozzle 23 is formed of a straight pipe having a jet port fixed thereto, and the axis thereof is substantially orthogonal to the transport surface of the chain conveyor 2.
The reason why the lower fixed nozzle 23 is constituted by a straight pipe is to improve the directivity of the compressed air to be ejected and to allow the compressed air to be blown to a target portion at a pinpoint.

In the first embodiment, the lower turning nozzles 22 and the lower fixed nozzles 23 are alternately arranged along the transport direction of the chain conveyor 2.
However, the arrangement of the lower swivel nozzle 22 and the lower fixed nozzle 23 is determined by the shape of the water removal or dust removal target, the water removal or dust removal location, and the like. For example, a plurality of lower swivel nozzles 22 may be continuously arranged, and one or a plurality of lower fixed nozzles 23 may be provided adjacent to the lower swirl nozzles 22 group. One or a plurality of lower swirl nozzles 22 may be provided adjacent to the group of the lower fixed nozzles 23 arranged side by side.

  Moreover, the 2nd injection unit U2 is provided above the base 1 demonstrated in FIG. The second injection unit U2 is configured to be rotatable within a range where the chain conveyor 2 is straddled or the chain conveyor 2 is opened as in the conventional case shown in FIG.

  An air box 24 is incorporated in the second injection unit U2 as described above, and an upper revolving nozzle 25, a side revolving nozzle 26, an upper fixed nozzle 27, and a side fixed nozzle 28 are provided in the air box 24. .

Each of the upper swirl nozzle 25 and the side swirl nozzle 26 has a structure in which the jet outlet swirls by the reaction force of the compressed air ejected therefrom, as in the conventional case.
The upper swirl nozzle 25 has its swivel axis substantially orthogonal to the transport surface of the chain conveyor 2, and the side swirl nozzle 26 has a swirl axis substantially parallel to the transport surface of the chain conveyor 2.

  Further, the upper fixed nozzle 27 and the side fixed nozzle 28 are formed of straight pipes to which the ejection ports are fixed. As described above, the upper fixed nozzle 27 and the side fixed nozzle 28 are configured by straight pipes in the same manner as described above, and the directivity of the compressed air to be ejected is enhanced and the compressed air is blown to the target portion at a pinpoint. To be able to do that.

The upper fixed nozzles 27 have their axes substantially orthogonal to the transport surface of the chain conveyor 2, and are alternately arranged along the transport direction of the upper swivel nozzles 25 and the chain conveyor 2.
Further, the side surface fixed nozzles 28 have their axes substantially parallel to the transport surface of the chain conveyor 2, and are alternately arranged along the side surface nozzles 26 and the transport direction of the chain conveyor 2.

Further, a support piece 29 is fixed to the air box 24 of the second injection unit U2, and a pressing roller 30 is provided on the support piece 29.
And when the 2nd injection unit U2 straddles and covers the chain conveyor 2, the said press roller 30 is pressed on the food pouch P which is the process target object conveyed by the chain conveyor 2. FIG. The pressing force at this time also has a function of opening the bottom of the food pouch P.

  That is, as already explained, the bottom portion of the food pouch P has a depth when viewed from the outside, so that when the bottom portion is conveyed in a collapsed state, the side swivel nozzle 26 and the side surface fixing are fixed to the bottom portion. If the compressed air of the nozzle 28 hits, it will be lost. For this purpose, the bottom side of the food pouch P is pressed by the presser roller 30 to open the side of the bottom.

  Note that, in the same manner as described above, the upper turning nozzle 25 and the upper fixed nozzle 27 and the side turning nozzle 26 and the side fixed nozzle 28 in the second injection unit U2 are arranged in the same manner as described above. It can be set freely according to the like.

Next, the case where water is removed from the food pouch P shown in FIG. 2 will be described.
The bottom part of the food pouch P is brought into contact with one guide 8, and the food pouch P is placed on the chain conveyor 2 with the opening opening side being along the other guide 9.
The food pouch P carried on the chain conveyor 2 has a space surrounded by the nozzles 22 and 23 provided in the first injection unit U1 and the nozzles 25 to 28 provided in the second injection unit U2. Will pass through.

Then, in the process of passing through the space surrounded by each nozzle as described above, the bottom portion is opened while being pressed by the pressing roller 30.
If compressed air is ejected from the lower turning nozzle 22 and the lower fixed nozzle 23, the upper turning nozzle 25 and the upper fixed nozzle 27 while maintaining the above state, the compressed air hits both the front and back surfaces of the food pouch P. .

At this time, the compressed air of the swirl nozzles 22 and 25 and the fixed nozzles 23 and 27 alternately hit, but the swirl nozzles 22 and 25 can blow compressed air over a wide range of the swirl range.
Moreover, the swirl nozzles 22 and 25 function to intermittently strike the food pouch P with compressed air according to the swirl speed, so that the water droplets attached to the food pouch P are lifted. It also functions.

  On the other hand, since the fixed nozzles 23 and 27 are linear and jet compressed air almost toward the pinpoint, stuck water droplets and dust can be scattered on the surface of the food pouch P. If persistent water droplets, dust, etc. are scattered on the surface of the food pouch P in this manner, it can be removed by the following swirl nozzles 22 and 25.

  Further, the side turning nozzle 26 and the side fixing nozzle 28 function as follows. These nozzles 26 and 28 blow compressed air to the bottom of the food pouch P, but the bottom of the food pouch P usually has a deep and narrow corner 31 as shown in FIG. If water droplets or dust enters such a corner 31, it cannot be dispensed by the side turning nozzle 26.

  In such a case, as shown in FIG. 3, if the bottom part of the food pouch 3, the side surface fixing nozzle 28 and the side surface turning nozzle 26 alternately move relative to each other, the side surface fixing nozzle 28 enters the corner 31. Water droplets and dust can be discharged to a wide area at the bottom and reliably blown off by the side turning nozzle 26.

  In any case, the swirling nozzle and the fixed nozzle act synergistically by taking advantage of their special characteristics, and can reliably remove water droplets and dust adhering to the processing object such as the food pouch P.

In the second embodiment shown in FIG. 4, a swivel nozzle 33 having a swivel axis approximately perpendicular to the surface above the surface 32 of the processing object T, and an axis line with respect to the surface above the surface. And a fixed nozzle 34 made of a straight pipe made substantially orthogonal to each other.
The principle that the swivel nozzle 33 swivels is the same as in the first embodiment.

The second embodiment thus configured is optimal for removing the water droplets and dust that have a deep hole 35 on the surface of the processing object T and have entered there.
That is, in the process in which the processing target T is conveyed in the direction of the arrow in FIG. 4, the fixed nozzle 34 first blows compressed air corresponding to the hole 35. Due to the pressure of the compressed air, water droplets and dust in the hole 35 are pushed out and scattered on the surface 32.

Thereafter, the swivel nozzle 33 blows off the water droplets and dust scattered on the surface 32. At this time, since the swivel nozzle 33 is swung, water droplets on the surface 32 can be removed within the swivel range.
As described above, the synergistic action of the swivel nozzle 33 and the fixed nozzle 34 can remove water droplets and dust from the processing target T having the holes 35.

The third embodiment shown in FIG. 5 is for the purpose of water removal or dust removal of the processing target T having a corner 39 composed of a container body 36 and a flange 38 on the lid 37 side, like a yogurt container. It is a thing.
In addition, a cylindrical processing target or a processing target such as a bottle is transported while standing on a transport belt, and the processing target is rotated during the transport process to remove water droplets and dust around it. I try to get rid of it.

  In the third embodiment, the swivel nozzle 40 that blows compressed air around the container body 36, the fixed nozzle 41 that blows compressed air to the corner 39, and the swivel nozzle 42 that blows compressed air to the lid 37. And.

  The principle that the swivel nozzles 40 and 42 swivel is the same as that of the first embodiment. The fixed nozzle 41 is also a straight pipe as in the first embodiment.

  In the third embodiment as described above, when the processing target T is transported while rotating in the transport belt, the fixed nozzle 41 blows compressed air to the corner 39, and water droplets or dust collected in the corner 39. Is dispensed around the container body 36. In this way, the water droplets and dust discharged around the container main body 36 are removed by the compressed air from the swirl nozzle 40.

Further, water droplets and dust on the lid 37 are removed by the swivel nozzle 42.
In any case, due to the synergistic action of the swivel nozzle 40 and the fixed nozzle 41, water droplets and dust on the processing target T having the corner 39 can be removed.

  In addition, each of the turning nozzle and fixed nozzle of the said 1st-3rd embodiment may be connected to the pipe provided with the angle adjustment function which can set an angle freely like a coolant hose, for example. Thus, if the pipe provided with the angle adjustment function is used, the jet direction of the compressed air can be freely set. In particular, if the jet direction of the compressed air from the fixed nozzle can be set freely, the compressed air can be reliably blown to necessary places such as holes and corners.

The fourth embodiment shown in FIG. 6 is a combination of a swivel nozzle 43 and an air knife 44 that is a fixed nozzle of the present invention.
Then, the long object is a processing object T, and the processing object T is conveyed in the direction of the arrow in FIG.

  The air knife 44 has a width substantially equal to or greater than the width of the processing object T, and jets compressed air corresponding to the width.

Therefore, in the process in which the processing target T is conveyed in the direction of the arrow, water droplets and dust on the processing target T are gathered together by the compressed air on the air curtain ejected from the air knife 44.
The water droplets and dust collected in this manner are blown away at once by the swivel nozzle 43.

Also in the fourth embodiment configured as described above, the swivel nozzle 43 and the air knife 44 that is a fixed nozzle act synergistically to reliably remove water droplets and dust on the processing target T.
