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.

For example, as this type of water remover, the one described in Patent Document 1 has been conventionally known, and FIGS. 6 and 7 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. .

  A first injection unit A shown in FIG. 7 is provided below the chain conveyor 2 on the base 1. 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, as shown in FIG. 6, a second injection unit B is provided above the base 1, and an air box 5 is incorporated in the second injection unit B, and the second injection unit B However, it can be rotated in a range where the chain conveyor 2 is straddled or the chain conveyor 2 is opened.

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 guides 8 and 9, one guide 8 is in contact with the bottom of the food pouch 3, as shown in FIG. 7, 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.

  Further, the swivel nozzles 4, 6, and 7 are automatically rotated by the injection reaction force of the compressed air injected from the injection ports 4a, 6a, and 7a, and blow the compressed air to the injection area E shown in FIG. The area of the injection area E at this time is determined by the turning trajectory of the injection circle Ec on the surface directly hit by the compressed air blown out from the injection ports 4a, 6a and 7a. The size of the injection circle Ec is determined by the diameters of the injection ports 4a, 6a and 7a and the distance L1 from the injection ports 4a, 6a and 7a to the injection surface on which the injection pressure acts.

  Moreover, when this injection area E is directly facing the injection surface of the processing object, the injection pressure with respect to the injection surface becomes the largest. However, if the injection area E is angled with respect to the injection surface, the injection pressure with respect to the injection surface is reduced.

Japanese Patent No. 4288899

  As described above, each of the swirl nozzles 4, 6, and 7 has a structure in which the injection angle is fixed and is kept constant in any case. If there is an inclined surface or a spherical surface, the injection area E with respect to each surface is angled, and the injection pressure is reduced. Therefore, there has been a problem that reliable water removal or dust removal cannot be performed.

  An object of the present invention is to provide a water removal or dust remover that can remove water or remove dust without weakening the spray pressure even if the shape of the object to be treated has many corners, or has slopes or spherical surfaces.

  In the first invention, a plurality of swirl nozzles are provided along the transport zone, and air is blown onto the processing object transported on the transport belt to remove water droplets and dust adhering to the processing object. The present invention relates to a dewatering or dust removing machine. The plurality of swivel nozzles are connected to a pipe having an angle adjustment function that allows the angle to be freely set.

  In the second aspect of the invention, the swivel nozzle and the fixed nozzle are provided along the transport band, and each nozzle is connected to a pipe having an angle adjusting function.

  According to the water removal or dust remover of the first invention, the spray nozzle spray area can be directly opposed to the processing target surface of the processing target, and the reduction of the injection pressure on the processing target can be prevented.

  According to the second aspect of the invention, the jet nozzle injection area can be directly opposed to the surface to be processed, and the fixed nozzle jet outlet can be directed to the target point.

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 a perspective view of a conventional water remover. FIG. 7 is an explanatory view showing the relationship between a food pouch conveyed by a conventional chain conveyor and a water removal machine. It is the schematic which showed the relationship between the injection opening of a turning nozzle, and an injection area.

  The first embodiment shown in FIG. 1 to FIG. 3 has an angle adjusting function for the type and arrangement of each nozzle, a point provided with a pressing roller for opening the bottom of the food pouch P, and the swivel nozzle and the fixed nozzle. The point connected to the pipe is different from the conventional example shown in FIGS. 6 and 7, and the other configuration is the same as the conventional example. Therefore, the same components as those in the prior art will be described using the same reference numerals as in FIGS.

The base 1 described with reference to FIG. 6 is provided with a chain conveyor 2 which is a transport belt 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 spout is swirled by the reaction force of the compressed air ejected from the swirl nozzle 22 in the same manner as the conventional swirl nozzle. 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.

  And each of the said lower side turning nozzle 22 and the lower side fixed nozzle 23 is being fixed to the 1st injection unit U1 via the pipes 22a and 23a provided with the angle adjustment function which can set an angle freely like a coolant hose. ing.

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 rotatable in a range where the chain conveyor 2 is straddled or the chain conveyor 2 is opened as in the conventional case shown in FIG. Since the second injection unit U2 has the same configuration as B in FIG. 6, it is omitted in the drawing.

  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 nozzles 25 to 28 is fixed to the air box 24 via pipes 25a, 26a, 27a and 28a having an angle adjusting function capable of freely setting an angle similarly to the coolant hose. Since 28a is hidden behind 26a, it does not appear on the drawing.

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.
And each of the upper turning nozzle 25 and the side turning nozzle 26 can bend the pipes 25a and 26a, and can freely set the angle of these turning axes.

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.
And each of these upper side fixed nozzle 27 and side surface fixed nozzle 28 can also bend the pipes 27a and 28a, and can freely set the angle of those turning axes.

The upper fixed nozzles 27 and the upper swivel nozzles 25 are alternately arranged along the transport direction of 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.
Prior to the water removal operation, the angles of the turning axes of the turning nozzles 22, 25 and 26 and the angles of the axes of the fixed nozzles 23, 27 and 28 are set in advance.
Then, the food pouch P is placed on the chain conveyor 2 while the bottom side of the food pouch P is brought into contact with one guide 8 and the opening side is placed 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 of the food pouch P, the side surface fixing nozzle 28 and the side surface turning nozzle 26 are alternately moved 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 substantially perpendicular to the surface 32 above the surface 32 of the object T to be processed and a surface above the surface to the surface. This is a combination with a fixed nozzle 34 made of a straight pipe having axes substantially orthogonal to each other.
The principle that the swivel nozzle 33 swivels and the angle of the swivel axis can be adjusted are 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.

  When the hole 35 is oblique, the axis of the fixed nozzle 34 is adjusted according to the angle of the hole 35. By doing in this way, even if there is an oblique hole, the water droplet in it can be removed.

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.
When the surface 32 is an inclined surface, the turning axis of the turning nozzle 33 is set perpendicular to the inclined surface.

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 and the angle of their swivel axes can be adjusted is the same as in the first embodiment. In addition, the fixed nozzle 41 is a straight pipe, and the angle of the axis can be adjusted 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.
