Description

Clean box and clean box consolidation system

The present invention relates to equipment technology that can maintain aseptic conditions with simple equipment and can meet hygiene management requirements, for example, when processing and packing fish and shellfish and processing it into frozen products.

Conventionally, for example, as a work to process fish and shellfish for food and make them into frozen products, in a clean work place where microbes and bacteria do not invade, fish etc. are washed to remove sputum, remove gills and viscera. After preparing, they drop their heads and put them into three pieces, peel them and use them as fillets for packing, vacuum packing and freezing. By the way, since such a series of work is carried out by workers entering a processing room such as a clean room, equipment etc. for removing dust, bacteria, etc. adhering to clothes of the workers when entering a room are necessary. In addition, there is a problem that when the room temperature or the like is a temperature zone suitable for keeping freshness of fish and shellfish, the burden on the worker is increased because a person enters the clean room and performs work.

On the other hand, as a food processing line that can easily create a space that satisfies a clean atmosphere, a tubular box is installed that straddles the flowing water groove on the floor, and a working hole is formed for putting a hand in the side wall of this box. There is known a technique in which a long glove-like food processing glove is connected to the working hole and the food processing equipment is accommodated in a cylindrical box. (For example, see Patent Document 1.) With this technology, it is not necessary for the operator to enter the clean room and work, so it is possible to save time and effort to remove dust, bacteria, etc. adhering to the clothes of the operator. It was also easy to make the temperature in the box a temperature zone suitable for maintaining the freshness of fish and shellfish.

JP 2007-255735 A

However, in the case of the technique of the above-mentioned patent document 1, for example, it is attempted to insert a hand into a food processing glove in a box and carry out operations such as cutting of fish, cutting of head, removing viscera, dropping three pieces, peeling In the case where the glove was attached, there was no room in the front, rear, left, and right, so it was found that the task of moving the hand was inconvenient and the task was difficult.
On the other hand, make the wall surface to which the glove is attached made of an elastic material such as rubber, or allow the wall surface to absorb the movement of moving the hand by providing a fold portion using a flexible material etc. If it is made to hold it, you can freely move the hands back and forth, but if wrinkles occur on the wall, dirt, bacteria, etc. may adhere to the wrinkles and remain even if you try to wash them away. The creases may not be dry even if dry, which is not preferable for hygiene control.

Therefore, the present invention eliminates the need for the operator to work in the clean room, and at the same time, makes it easy to set the temperature in the box to a temperature zone suitable for maintaining the freshness, and the operator does the work. An object of the present invention is to make it possible to easily configure an installation which is easy to perform and in which bacteria, dirt and the like do not easily adhere to the inside.

In order to achieve the above object, the present invention provides an outlet and an inlet for carrying in and out articles, an airtight door which can be opened and closed in a sealed state of the outlet and the inlet, and a pair of left and right hands provided on the front wall of the box. An insertion hole and a sleeve fixed to the back of the front wall behind the hand insertion hole and through which the arm above the wrist can pass, and with the hand inserted from the hand insertion hole, the inside of the box is exterior In the clean box capable of defining an independent space isolated from the inside of the box, air can be introduced and discharged, and a valve for adjusting the internal pressure of the box is provided in the air outlet, The front wall on which the pair of hand insertion holes are provided is made of a flexible and stretchable material, and the material on the upper surface side of the box is made of a material which allows the inside to be seen through.

That is, when the hand is inserted into the sleeve through the hand insertion hole and the hand is inserted into the box, the inner surface of the sleeve is in close contact with the body near the wrist so that the inside of the box is sealed. However, because the front face is flexible and stretchable, the hands can be moved freely.
As such a flexible and stretchable material, for example, a material such as chloroprene rubber (CR) used in a dry suit or the like can be applied. By using such a material, for example, Even when the hand is inserted into the sleeve from the hand insertion hole, the front wall will expand and contract back and forth and right and left along with the movement of the hand, increasing the degree of freedom, for example when the elbow hits But it is safe without pain. For this reason, it is suitable especially when the movement of the hand is intense in the box.
Also, when cleaning the inner surface of the front wall, introduce air and increase the internal pressure by adjusting the valve of the air outlet to expand the front wall like a balloon to eliminate wrinkles, leaving bacteria etc. Nothing can be washed out cleanly, it can be dried cleanly even when dry.
Also, by making the upper surface side of the box a material that allows the inside to be seen through, it is possible to work while checking the internal condition from the upper surface side, and it is possible to work easily.
If a blowout hole for blowing out ozone is provided as a sterilizing means in such a clean box as in the fifth aspect, the germicidal effect of the ozone kills the bacteria adhering to the inside of the clean box and the hand. It can be more hygienic.

Further, in the present invention, a discharge port and a carry-in port for carrying articles in and out, a sealed door which can be opened and closed in a sealed state of the carry-out port and the carry-in port, a pair of left and right hand insertion holes provided on the front wall of the box The front wall behind the hand insertion hole has a sleeve that is fixed to the back of the front wall and can pass the arm above the wrist, and the inside of the box is isolated from the outside when the hand is inserted from the hand insertion hole In a clean box capable of defining a space, air can be introduced and extracted inside the box, and a valve for adjusting the internal pressure of the box is provided in the air outlet, and the pair of hands The front wall on which the insertion hole is provided is made of a transparent and flexible material, and at the same time, is configured to expand as air pressure in the box increases.

In this case, the inside of the box can be seen through from the front side of the box, and the space inside the box can be widened up and down, which makes the work easier.
In addition, as an example of a specific configuration in the case of making a front wall into a form which swells when the air pressure in a box increases, for example, in addition to comprising a front wall with elastic materials, such as rubber, for example, there is no elasticity. When a sheet-like material or a sheet-like material having poor stretchability is fixed to a frame or the like on the front side, there is room in the case of extending or shrinking by providing a crease at the fixing portion to the frame or the like. It is possible to apply a method that
In this case as well, the freedom of movement of the hand is enhanced, and if the inner surface of the front wall etc. is washed and expanded, washing can be carried out to prevent the situation where bacteria etc. remain and to wash out more beautifully.

Further, in the present invention, a window portion of a predetermined size made of a transparent, less wrinkle-resistant material is attached to the height position of the middle upper portion of the left and right hand insertion holes of the front wall.
That is, when trying to see through the inside from the front side, if the internal pressure in the box is not applied, the front wall may become slack and wrinkles may occur to make it difficult to see the inside. . For this reason, if the window part which is more resistant to wrinkles is stuck from the inner surface side or the outer surface side, no wrinkles will be generated in the same part, so the internal condition can be surely recognized and confirmed.
Here, as a specific size of the window portion, for example, a rectangular shape or an elliptical shape having a side of about 10 to 30 cm is preferable.

Further, according to the present invention, a disposable glove etc. is closely attached to and detached from the sleeve at the tip of the sleeve so that it can be replaced through the hand insertion hole.

By doing this, for example, even when the hands are dirty, it is possible to work more hygienically by wearing disposable gloves, and even when parts of the gloves are broken or torn during the operation. It is convenient because it is easy to replace only the glove portion through the insertion hole.

In the present invention, the temperature of the air introduced into the clean box is made adjustable.
If the temperature of the air introduced into the clean box can be adjusted in this way, for example, when handling fresh fish, only by introducing the air adjusted to a temperature suitable for maintaining the freshness of about 5 to 10 ° C. in the box. You can work well while keeping the freshness.

Further, in the present invention, in a clean box connection system in which processing on an article can be continuously performed by connecting two or more clean boxes according to any one of claims 1 to 4, A connection box is disposed between adjacent clean boxes, and the connection box is provided with communication ports communicating with the outlet of the clean box on one side and the inlet of the clean box on the other side, and Separately, there is an input port where materials can be input into the clean box.

Under the present circumstances, if the said connection box is provided with the disinfection means for disinfecting the inside of a connection box, the inside of a connection box can be made more hygienic.
If the article handled by the clean box connection system is a food, for example, the temperature in the clean box can be set to a temperature range suitable for storage of the food, and it is convenient because it is hygienic.

In a clean box provided with sleeves fixed to the front wall back side of the back side of a pair of left and right hand insertion holes provided on the front wall of the box, air can be introduced and extracted, and the box to the air outlet A valve for adjusting the internal pressure is provided, and the front wall is made of a flexible and expandable bulging material, and at the same time the material on the upper surface side of the box is made of a material which can see through the inside, or By forming the front wall by a transparent and flexible material, and by forming a material that swells as air pressure in the box increases, the degree of freedom in moving the hand in the clean box increases. It is convenient because the inside situation can be viewed from the top side or the front side. In addition, if the internal pressure is increased as needed to inflate the front wall, it is possible to prevent such a problem that foreign bacteria, foreign matter and the like adhere to the wrinkles and the like so as not to fall off, and a more hygienic clean room can be achieved. In addition, when the front wall is made of a transparent material, the inside can be reliably recognized by sticking a more resistant wrinkled transparent window to a predetermined location.
At this time, if a sterilizing means is provided in the clean box, more sanitary equipment can be obtained, and if it is possible to replace the tip portion from the wrist through the hand insertion hole, for example, disposable gloves etc. It is cheap and convenient because it can be used.
In addition, in a clean box connection system where processing for articles can be continuously performed by connecting two or more clean boxes, a connection box can be inserted between the clean boxes, and materials and the like can be input. By providing the holes, materials and the like necessary for work in the clean box can be taken in and out, and if the connecting box is provided with a sterilizing means, it can be made more hygienic. And if it is set as foodstuffs as goods to work, it can be set as a suitable installation.

A lid 17 is provided, and by opening the sealing lid 17, dust and the like in the collecting unit 15 can be dropped to the collecting unit 16. The sealing lid 17 can be opened and closed by an external operation by any means.

By the way, at the tip of the sleeve portion 7, a disposable glove 9 or the like can be closely joined via the joining tool 18, and the proximal end portion of the sleeve portion 7 has a hand insertion hole 6. It is closely fixed to the front wall 5 of the peripheral portion, and in the present embodiment, the sleeve portion 7 is easily removed from and attached to the front wall 5.

The glove 9 is made replaceable through the hand insertion hole 6 with respect to the sleeve portion 7. Hereinafter, an example of the replacement procedure and the joint structure will be described based on FIG.
The joining members 18 in this embodiment are a concave member 18m and a convex member 18t which are fitted to each other, and the concave member 18m has a concave portion formed in the widthwise intermediate portion of the ring-shaped band-like ring portion. In the shape member 18t, a convex portion is formed at a widthwise intermediate portion of the ring-shaped band-like ring portion, and the convex portion is fitted in the concave portion.

Then, when attaching a new glove 9 to the end of the sleeve 7, as shown in FIG. 4A, the sleeve 7 was pulled out of the clean box 2 through the hand insertion hole 6 of the front wall 5 so as to turn over. Thereafter, the convex portion of the convex member 18t is fitted outward on the outer peripheral portion on the tip end side of the sleeve portion 7, and the sleeve portion protruding to the distal end side from the convex member 18t is folded back toward the inner upper portion.
Next, as shown in FIG. 4 (b), the tip of the glove 9 is inserted into the tip cylindrical portion of the sleeve 7, and a part of the proximal end of the glove 9 protrudes from the inside of the sleeve of the sleeve 7 to the outside After inserting to the state, the overhanging part is folded back toward the inside upper part, and then the concave member 18m is covered on the double overlapping part, and the convex part of the convex member 18t is fitted in the concave part of the concave member 18m Match (Figure 4 (c)).

As a result, the sleeve 7 and the glove 9 of the operation glove 7 are joined to each other without a gap. And if a hand is inserted in such a glove 9 and it turns into the inside of the clean box 2 as shown in FIG.4 (d) so that the upturned upper part 7a may be returned, attachment of the glove 9 will become Complete. Of course, the diameter of the ring-shaped joint 18 is smaller than the diameter of the hand insertion hole 6.

By the way, as shown in FIG. 2, the connection box 3 is provided on both sides with a communication port c communicating with the inlet a of the clean box 2 and the outlet b, and is provided with the inlet 21 on the front side. Moreover, in the connection box 3, an ozone blowout pipe (not shown) capable of blowing out ozone is connected.
In addition, the communication port c is provided only in one side surface of the insertion box 3i and the payout box 3d, and the communication port on the other side is closed. A pair of transport rails 10 is provided inside the connection box 3, the insertion box 3 i and the payout box 3 d.

An example of the specific configuration of the clean box connection system 1 as described above will be described based on FIG. 5 by taking a series of operations from processing and packing fresh fish as an example.
Coupling system 1 of the clean box shown in Figure 5, first the throw box 3i to inject fresh fish to the downstream, a first working clean box 2 ₁ for performing a first work, for performing a second work through the clean box 2 ₂ for 2 work, a third working clean box 2 ₃ for performing a third task, a fourth working clean box 2 ₄ for performing a fourth operation, the respective connection box 3 Are connected together, and the delivery box 3d is connected at the most downstream side.

Then, air kept at, for example, about 5 ° C. to 10 ° C. and ozone for sterilization are blown into the respective clean boxes 2 ₁ to 2 ₄ so that the inside of the boxes can be cooled and sterilized simultaneously. Then, in this state, the first working clean box 2 _1, by opening the sealing doors 4a of entrance a, moves the fish on the tray in the upstream side of the charging box 3i in his box, for example, fish Perform preparatory work such as washing, removing sputum and removing gills and internal organs. Then, this operation is responsible worker of the clean box 2 _1, inserts a hand into the box through the sleeves 7, to work while seeing through the inside of a transparent upper wall 8.
When the work is finished, the first working clean box 2 ₁ representative operator, processed fish placed on the tray, the fish on the tray by opening the sealing doors 4b of outlet port b to the downstream connection box 3 Move it.

The second worker's clean box 2 The worker in charge of ₂ moves the fish on the tray in the connection box 3 on the upstream side into his / her box in the same manner, drops his head and lowers it into three pieces and takes the peels . Then, when the three-sheet unloading operation is finished, the fish is placed on the tray and moved to the downstream connection box 3.

The third worker's clean box 23. The worker in charge of the _third move the fish on the tray in the upstream connection box 3 into his own box in the same manner, and cut it into a block size for vacuum packing. Thereafter, the paper is wiped with water, placed on a tray, and moved to the downstream connection box 3.
The fourth worker's clean box 2. The worker in charge of ₄ moves the fish on the tray in the connection box 3 on the upstream side into his / her box in the same manner, puts the block in a nylon pack and vacuums it with a vacuum pack machine. When preparation for packing and freezing is completed, it is moved to the downstream payout box 3d. Then, after packing is taken out from the delivery box 3d, the weight is measured by a scale, and a quality indication label is attached and frozen by a freezing machine.

In the above operation, for example, the degree of slack of the front wall 5 can be increased during movement by increasing the degree of freedom in moving the hand, and the inside can be sterilized or cleaned. When the front wall 5 is expanded by increasing the internal pressure in the box, the inside wall of the front wall 5 can be cleaned and disinfected cleanly without bacteria or dirt adhering to the wrinkles and the like. Then, dust, cleaning water and the like generated during processing are dropped to the lower collecting portion 15 and appropriately accumulated by the opening of the sealing lid 17 so as to be accumulated and discharged to the lower collecting portion 16.

For this reason, compared with the installation which a worker enters into a clean room, it can constitute extremely cheaply, and since a person does not get in directly inside, the temperature zone in a box is freshened. Setting a relatively low temperature suitable for maintenance does not burden the workers.

In addition, when working with gloves 9, if gloves 9 are damaged during work, only gloves 9 can be easily replaced through hand insertion hole 6, and each clean box 2 when a tool such as a knife for use in the _1-2 ₄ as damaged, by injecting, dispensing from inlet 21 of the connecting box 3 can be easily replaced.

Next, the clean box 2 of the second configuration example in which the inside can be seen through from the front side of the box will be described based on FIGS. 6 to 8.

In this case, less expensive or less stretchable material can be used as the material of the front wall 5, and moreover, a wide space above and below the box can be secured. The configuration of the sealing

door

4a, 4b, etc. for opening and closing the side wall, the inlet a and the outlet b, and the like are the same as in the above example, but the upper surface wall 8 does not have to be a transparent material. The flexible material is used, and as shown in FIG. 7, by providing and attaching folds z to both side walls, the top wall 8 and the bottom wall, room is provided for up, down, left, and right movement, and It is made to swell when the internal pressure rises.

Then, in this embodiment, the grooves of the sash groove rail 20 for the screen door are attached to the fronts of both side walls, the upper surface wall 8 and the bottom wall with the folds z attached to the end of the front wall 5 The front wall 5 has room by inserting it and pressing it with the pressing rubber 21 so that it can be moved freely even if the hand inserted into the box from the hand insertion hole 6 is moved, and the air pressure in the box is increased. The front wall 5 swells so that cleaning and the like can be performed cleanly.

Further, in this case, since the inside of the box is viewed from the front wall 5, the height of the box can be increased, and when the internal pressure is small, wrinkles etc. occur to make it difficult to check the inside. In order to prevent the problem, in the present embodiment, a window 22 made of a transparent, less wrinkle-resistant material is attached to the height position of the middle upper portion of the left and right hand insertion holes 6.
A sleeve 7 is detachably provided on the back side of the hand insertion hole 6 in the same manner as in the above example, and a disposable glove 9 is detachably attached to the tip of the sleeve 7 through the hand insertion hole 6. The configurations and the like used in the above are the same as in the above example.

Also, the window 22 may be attached to the front of the transparent front wall 5 or to the back, but even when the internal pressure of the box is not applied by such a window 22, the same part may be attached. It is possible to visually recognize the internal state without causing wrinkles.
Further, in the present embodiment, the hooking

members

23 and 24 are provided on the peripheral part of the front wall 5 and on the front part of the top, side, and bottom parts, and rubber 25 is interposed between the hooking

members

23 and 24. By doing this, even when the internal pressure is not applied, the front wall 5 is expanded substantially uniformly.

Also in the clean box 2 as described above, the freedom in moving the hand can be increased similarly to the above example, and when the inside is sterilized or cleaned, the internal pressure in the box is increased. By inflating the front wall 5, the inner surface of the front wall 5 can be cleaned and disinfected cleanly.
In addition, since the internal space can be widened vertically, a sufficient working space can be secured, and furthermore, the front wall 5 can be configured at a lower cost.

The present invention is not limited to the embodiments described above. A device having substantially the same configuration as the matter described in the claims of the present invention and having the same function and effect belongs to the technical scope of the present invention. For example, in the connection system of clean boxes, the number of connections of clean boxes 2 and the like are examples. Moreover, the articles handled by the coupling system are also an example. Further, the material of the front wall 5 in the first configuration example is not limited to chloroprene rubber, and the rubber 25 on the periphery of the front wall 5 in the second configuration example is not an essential requirement. Furthermore, the sterilizing means is not limited to ozone.

Maintaining the freshness of food, especially when it is applied to a system that handles food, it is possible to manage hygiene with a simple system without installing large facilities such as a clean room, and since no worker can enter inside. Even if the temperature zone is set to a suitable temperature zone, it does not burden the operator and is preferable.
