Description

The present invention relates to a soundproof box for a water removing device that blows off water droplets and the like adhering to the surface of an object to be treated by compressed air.

Conventionally, a device has been known in which water droplets on the surface of an object to be treated are blown off by the jetting force of compressed air.
As this type of device, for example, there is a water removal device shown in FIG.
In this water removal device, a net conveyor 2 is provided on the upper part of the device main body 1, and an object to be processed is placed and conveyed on the transfer surface 2a of the net conveyor.
Further, a unit cover 3 capable of covering or releasing the transport surface 2a of the net conveyor 2 is provided on the upper surface of the apparatus main body 1, and an air injection unit 4 is mounted in the unit cover 3. A plurality of air injection nozzles (not shown) are attached to the air injection unit 4, and the air injection nozzles inject compressed air guided from a compressed air source (not shown), and the injection port swivels due to the injection reaction force. ..

Further, an air injection unit 5 is provided below the net conveyor 2, and the air injection unit 5 is also provided with a plurality of air injection nozzles (not shown).
Then, if this device is operated with the unit cover 3 closed, compressed air is injected from the air injection nozzles of the upper and lower air injection units 4 and 5 toward the object to be processed on the transport surface 2a, and the object to be processed is processed. Water droplets adhering to the surface of an object can be blown off.

Further, a soundproof box 6 is attached to the device main body 1 of the water removing device so as to be openable and closable so that the unit cover 3 can be covered and released.
The reason why such a soundproof box 6 is provided is as follows.
While the water removing device is in operation, compressed air is injected from a large number of air injection nozzles. Therefore, the injection sound of compressed air, the turbulent sound after injection, the collision sound of air with the object to be processed, the vibration sound of the object to be processed on the transport surface 2a, etc. are generated, which become a noise source. be. This noise was very unpleasant for workers who had to work around the water remover and was sometimes a health hazard. Therefore, the unit cover 3 is covered with the soundproof box 6 to reduce ambient noise.

The noise box 6 is made of a metal such as stainless steel, and a sponge-like sound absorbing plate (not shown) is adhered to the inner surface of the box body 7 having a size for covering the unit cover 3 and an entrance / exit for an object to be processed. It is glued with. The sound absorbing plate was designed to absorb the noise generated in the unit cover 3 .

Japanese Unexamined Patent Publication No. 2005-345018 Jikkai Sho 55-142792

Since the box body 7 covers the unit cover 3 of the water removal device, the box is blown off by compressed air, and water droplets ejected from the entrance / exit of the object to be processed of the unit cover 3 and water vapor discharged from the exhaust port 8 are discharged from the box. It may adhere to the inside of the main body 7 .
Water droplets and dust adhering to the inside of the box body 7 must be removed by cleaning, but it is troublesome to sufficiently remove the water droplets and dust adhering to the sponge-like sound absorbing plate.
Further, since the sound absorbing plate is adhered to the box body 7 with an adhesive, it is difficult to clean the sound absorbing plate.

Further, if the amount of water absorbed by the sound absorbing plate increases, the sound absorbing effect deteriorates. In addition, if the sound absorbing plate is left to absorb moisture, it may cause mold to grow and the hygienic environment cannot be maintained.
However, it takes time to dry the sound absorbing plate bonded to the box body 7 with an adhesive .
Therefore, in particular, when the water removing device is incorporated in a food production line, it is necessary to clean the inside of the box body 7 to keep it clean at all times.

However, as described above, a sponge-like sound absorbing plate is adhered to the inside of the box body 7, and it takes time and effort to remove water droplets and dust adhering to the sound absorbing plate .

As a result, there is also a problem that the time for stopping the water removal process becomes long due to the cleaning work inside the soundproof box, and the production efficiency in the production line including these processes is lowered.
Also, even if you try to replace the dirty sound absorbing plate, you must forcibly remove the sound absorbing plate adhered with the adhesive from the box body 7, and if the adhesive remains, attach a new sound absorbing plate cleanly. Sometimes I couldn't.

An object of the present invention is to provide a soundproof box for a water removing device that can easily clean and replace the sound absorbing plate.

According to the first aspect of the present invention, compressed air is injected toward a processing object transported by the transport means into a unit cover that can be opened and closed with respect to the transport surface of the transport means provided in the main body of the apparatus. A soundproof box used for a water removal device with a built-in air injection unit that blows off water droplets adhering to the object to be treated, and the box body that covers and releases the unit cover can be opened and closed on the device body. At the same time, on the four inner side surfaces where the box body stands up in the closed state, a channel-shaped weight support portion provided along the lower end side opening edge and a channel extending in a direction parallel to or orthogonal to the weight support portion are provided. A fall-prevention support part is provided, and a sponge-like side surface sound absorbing plate that covers each inner side surface is fitted into the channel between the weight support part and the fall-prevention support part so that the box body can be attached and detached . A channel-shaped ceiling support portion is provided on the ceiling surface along the contour of the ceiling surface, and the outer peripheral end of a sponge-shaped ceiling sound absorbing plate covering the ceiling surface is fitted into the channel of the ceiling support portion to be attached and detached. At the same time, the lower end of the side surface sound absorbing plate is covered with the channel-shaped weight supporting portion, and the moisture absorbed by the side surface sound absorbing plate is held by the weight supporting portion .

The second invention is the dimension in the height direction in which the sound absorbing plate for the side surface is maintained at a distance corresponding to the thickness of the sound absorbing plate for the ceiling between the upper end thereof and the ceiling surface in a state where the box body is closed. The above distance constitutes the above ceiling support portion.

In the third invention, either the side sound absorbing plate or the ceiling sound absorbing plate is composed of a plurality of divided sound absorbing plates, and the side surface or the ceiling surface covered with the divided sound absorbing plates has the divided sound absorbing plate. A channel-shaped support portion into which the outer periphery of the plate is fitted is provided.

According to the present invention, the side surface and the ceiling surface are covered with a sponge-like sound absorbing plate to exert a soundproofing effect.
Then, since the sponge-shaped sound absorbing plate can be easily attached to and detached from the channel while bending, the sound absorbing plate separate from the box body can be cleaned, washed, and dried.

Therefore, the workability of cleaning the inside of the box body is improved, and the water removing device is not stopped for a long time for cleaning and drying the inside of the box body, and the production efficiency is not lowered.
In addition, the dirty sound absorbing plate can be easily replaced with a new sound absorbing plate.
Therefore, it becomes easy to keep the inside of the box body clean.
Further, it is possible to keep the sound absorbing plate in a dry state to prevent the sound absorbing effect from being lowered due to water absorption.

Further, the outer periphery of the sound absorbing plate is supported by a channel-shaped support portion, but the weight support portion reliably supports the weight of the side sound absorbing plate, and the fall prevention support portion tilts the upright side sound absorbing plate. Can be prevented. In particular, even if the weight balance of the sound absorbing plate is lost due to water absorption, it can be reliably supported, so that the side sound absorbing plate does not vibrate and the sound absorbing effect does not deteriorate.
Further, when attaching the sound absorbing plate, it is only necessary to insert the outer periphery into the channel while bending the sound absorbing plate, and the attaching work is easy.
In this way, reliable support can be realized while facilitating the attachment / detachment of the sound absorbing plate.

According to the second invention, the space between the upper end of the side sound absorbing plate and the ceiling surface functions as a channel-shaped ceiling support portion, and the ceiling sound absorbing plate is inserted into this space to support the sound absorbing plate. Can be done. Therefore, the entire ceiling surface can be covered with the ceiling sound absorbing plate without using a separate channel-shaped member to form the ceiling support portion. In addition, the number of parts can be reduced because a separate member is not required for the ceiling support portion.

According to the third invention, the sound absorbing plate covering each surface of the box body can be used as a divided sound absorbing plate to reduce the individual size. The smaller the sound absorbing plate, the easier it is to handle, and the workability of attaching and detaching to the box body is improved.
Further, the outer periphery of the sound absorbing plate is supported by the support portion, but if the outer periphery of the divided sound absorbing plate having a small area is supported, it can be supported more reliably than the sound absorbing plate having a large area.

It is a weight support part of the present invention that supports below.
Further, other channel members 28, 31, 32, 33, 34, 35 form a fall prevention support portion for preventing the side surface sound absorbing plate 36 supported by the weight support portion from falling.
The channel members 28 and 35 are fall prevention support portions parallel to the weight support portion, and the channel members 31, 32, 33 and 34 are fall prevention support portions extending in a direction orthogonal to the weight support portion.
The fall prevention support portion may be either one that extends in parallel with the weight support portion or one that extends in the direction orthogonal to the weight support portion.

Next, the side surface 12 side will be described. As shown in FIG. 1, the side surface 12 is a rectangular surface facing the side surface 10 and not forming the peephole 10a or the like. The channel-shaped support portion 21 described above is formed at the lower end (see FIG. 2).
Also on the side surface 12, a channel member 37 (see FIG. 7) similar to the channel member 28 on the side surface 10 is fixed at a position facing the channel member 28, and constitutes a fall prevention support portion extending in parallel with the support portion 21. are doing.
That is, the channel member 37 also has an opening facing the opening of the support portion 21 at a position where the space corresponding to the thickness of the ceiling sound absorbing plates 27a, 27b, 27c is maintained between the channel member 37 and the ceiling surface 14, and the support portion 21 is also provided. It is a member that extends in parallel with. Then, both ends in the longitudinal direction of the channel member 37 are kept between the side surfaces 11 and 13 so as to maintain a distance corresponding to the thickness of the side surface sound absorbing plates 29 and 30 covering the side surfaces 11 and 13.

The support portions 16, 17, and 18 that support the lower end of the side sound absorbing plate 29 are the weight support portions of the present invention along the lower end opening edge of the box body 9, and the support portions 19, 20 that extend vertically. And the upper channel member 39 constitutes a fall prevention support portion.

Further, in this embodiment, the width of the channel member 31 fixed to the side surface 10 to support one end surface in the width direction of the side surface sound absorbing plate 36 covering the side surface 10 and the width of the side surface sound absorbing plate 38 covering the side surface 12. The side surface sound absorbing plate 29 is fitted in a space between a channel member (not shown) fixed to the side surface 12 to support one end surface in the direction and the side surface 11 (see FIG. 3). Therefore, the distance between the channel member that supports the side surface sound absorbing plates 36 and 38 and the side surface 11 functions as a channel-shaped fall prevention support portion that supports the side surface sound absorbing plates 29.

Further, since the side surface 13 facing the side surface 11 has a symmetrical shape to the side surface 11, the side surface sound absorbing plate 30 covering the side surface 13 is supported by the same member as the member provided on the side surface 11.
Specifically, the opening is made to face the opening of the support portion 22 at a position facing the channel member 39 of the side surface 11, that is, at a position where a distance corresponding to the thickness of the ceiling sound absorbing plate 27a is maintained between the ceiling surface 14 and the channel member 39. , The channel member 40 (see FIGS. 3 and 7) extending in parallel with the support portion 22 is fixed. The channel member 40 has a length over substantially the entire length of the side surface 13 in the width direction.

The gate-shaped side surface sound absorbing plate 30 is supported by the channel member 40, the support portions 22, 23, 24 which are weight support portions on the lower end side, and the support portions 25, 26 which are fall prevention support portions. ..
Also on the side surface 13 side, the distance between the side surface 13 and the channel member 32 for supporting the end faces of the side surface sound absorbing plates 36 and 38 in the width direction and the channel member (not shown) fixed to the side surface 13 is the side surface. It functions as a channel-shaped fall prevention support portion that supports the sound absorbing plate 30.

As described above, the side sound absorbing plates 29, 30, 36, and 38 covering the four sides of the box body 9 of this embodiment are all supported by the outer periphery thereof being fitted into the channel of the support portion.
Therefore, the outer periphery of the side sound absorbing plates 29, 30, 36, 38 can be taken out from the channel by bending the whole, and can also be fitted into the channel.

Next, the support of the ceiling sound absorbing plates 27a, 27b, 27c that cover the ceiling surface 14 will be described.
In this embodiment, the ceiling surface 14 is covered with the ceiling sound absorbing plates 27a, 27b, 27c having an area obtained by dividing the ceiling surface 14 into three equal parts. The sound absorbing plates 27a, 27b, 27c for each ceiling are the divided sound absorbing plates of the present invention.
Then, on each of the side surfaces 10, 11, 12, and 13, the channel members 28, 37, 39 are kept at a distance corresponding to the thickness of the ceiling sound absorbing plates 27a, 27b, 27c from the ceiling surface 14 as described above. , 40 are fixed. The channel members 28, 37, 39, 40 fixed to the four side surfaces in this way are provided along the contour of the ceiling surface 14, and these four channel members 28, 37, 39, 40 form a rectangular frame. ing.

The ceiling sound absorbing plates 27a, 27b, 27c can be fitted between the channel members 28, 37, 39, 40 and the ceiling surface 14 to function as a channel-shaped ceiling support portion. In short, the channel members 28, 37, 39, 40 and the ceiling surface 14 are combined to form a channel-shaped ceiling support portion, and the ceiling sound absorbing plates 27a, 27b, 27c are composed of the channel members 28, 37, 39, 40. It can be pushed between the frame and the ceiling surface 14.
By pushing the ceiling sound absorbing plates 27a, 27b, 27c between the frame and the ceiling surface 14 in this way, the edges of the ceiling sound absorbing plates 27a, 27b, 27c are brought into close contact with the side surfaces 10, 11, 12, and 13. Can be made to.

In this embodiment, the side sound absorbing plates 29, 30, 36, 38 covering the side surfaces 10, 11, 12, and 13 have a distance corresponding to the thickness of the ceiling sound absorbing plate between the upper end thereof and the ceiling surface 14. It is a sound absorbing plate for a side surface having dimensions in the height direction in which the ceiling is held.
Therefore, in this embodiment, the channel members 28, 37, 39, and 40 have both the function of the fall prevention support portion of the side sound absorbing plate and the function of the ceiling support portion, respectively.

Further, in this embodiment, since the divided sound absorbing plate is used as the sound absorbing plate for the ceiling, the rod-shaped support members 41 and 42 are fixed to the ceiling surface 14 as the supporting portion for supporting the outer periphery of each divided sound absorbing plate. are doing. As shown in FIG. 6, these support members 41 and 42 are metal members having channels formed on both sides when fixed to the ceiling surface 14.
Then, a ceiling sound absorbing plate 27a is bridged between the support member 41 and the channel member 40, and a ceiling sound absorbing plate 27b is placed between the support members 41 and 42 between the support member 42 and the channel member 39. The sound absorbing plate 27c for the ceiling will be hung.

As described above, since the ceiling sound absorbing plates 27, 27b, 27c are also supported by being fitted into the channel-shaped support portion, they can be easily removed from or fitted from the channel of the support portion.
Further, the ceiling sound absorbing plate 27b located at the center of the three ceiling sound absorbing plates 27a, 27b, 27c is formed with an opening corresponding to the exhaust windows 14a, 14b formed on the ceiling surface 14, and the exhaust window is formed. A fan attached to 14a and 14b discharges steam and the like in the box body 9.

As described above, in the soundproof box of this embodiment, the side sound absorbing plate and the ceiling sound absorbing plate that cover the inside of the box body 9 can be easily attached to and detached from the channel of the support portion. Therefore, when cleaning the inside of the box body 9, the sound absorbing plate can be removed and the box body 9 and the sound absorbing plate can be cleaned separately. Since the sound absorbing plate can be removed from the box body, it is easy to clean the sound absorbing material, dry it, or replace it with a new sound absorbing plate.
Therefore, the inside of the box body 9 can be kept clean without taking time and effort for cleaning and replacement.

Further, in this embodiment, the weight support portion and the fall prevention support portion ensure that the side sound absorbing plate is supported. Therefore, while making the side sound absorbing plate removable, it is possible to prevent the sound absorbing plate from shifting when the water removing device is used. In particular, when used in a water removal device, the sound absorbing plate may absorb water, resulting in an increase in weight or an imbalance in weight. By providing the fall prevention support portion, it is possible to prevent the side sound absorbing plate from falling or slipping.

The box main body 9 is configured by providing the support portions on the plate materials constituting the respective surfaces 10, 11, 12, 13, and 14, and then combining them in a box shape and welding the joint portions.
Further, each of the above-mentioned support portions does not need to support the entire circumference of the sound absorbing plate. The support portion may have a length capable of supporting each sound absorbing plate within a range in which the sound absorbing plate does not shift or fall, or may be composed of a plurality of members divided in the longitudinal direction.

Further, in this embodiment, the ceiling sound absorbing plate is composed of three divided sound absorbing plates, but the number of divided sound absorbing plates for the ceiling may be any number, or may be composed of one member.
Further, the side sound absorbing plate may be composed of a plurality of divided sound absorbing plates.
When the sound absorbing plate for the ceiling or the sound absorbing plate for the wall surface is composed of a plurality of divided sound absorbing plates, the weight of each member is smaller than that of the case where the sound absorbing plate is composed of a single member. It has the advantage of being easier. On the other hand, the number of members to be attached / detached increases, which may take time and effort. Therefore, it is preferable to determine the number of the divided sound absorbing plates according to the area of the side surface or the ceiling surface, the weight of the sound absorbing plates, and the like.

Further, the weight supporting portion that supports the lower end of the sound absorbing plate may be formed by attaching a channel member different from the side surface, instead of forming the plate member constituting the side surface by bending as described above.
Further, the weight support portion may be formed with drainage holes continuously in the longitudinal direction thereof so that the moisture absorbed by the sound absorbing plate can be discharged to the outside.
Although the soundproof box attached to the water removal device has been described in the above embodiment, the box body 9 can be used as a soundproof box for the dust removal device, and the same effect as described above can be obtained in that case as well.

Further, a vibration damping plate may be interposed between the sound absorbing plate and each surface to further enhance the soundproofing effect.
The vibration damping plate can be fixed to the side surfaces 10, 11, 12, 13 and the ceiling surface 14 with an adhesive or the like while avoiding the respective support portions. Since this vibration damping plate is covered with a sound absorbing plate, water droplets and dust do not directly adhere to it, and since it is not sponge-like like the sound absorbing plate, moisture does not soak into it. Moisture and dust adhered to the surface of this damping plate, so if you remove the sound absorbing plate, you can easily wipe them off.

It is most suitable for water removal or dust removal equipment used in processes with strict hygiene control such as food processes.
