Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a book sterilizing method and a book sterilizing apparatus. More specifically, the present invention relates to a book sterilizing method and a sterilizing apparatus suitable for sterilizing and recycling old books.

[0002]

2. Description of the Related Art Conventionally, books are often recycled through used book stores and the like, and various devices for recycling used books have been provided. For example, in order to improve hygiene when recycling books, a disinfecting apparatus for books has been provided as described in Japanese Utility Model Registration No. 3062281.

[0003] The sterilization apparatus is configured to sterilize the book conveyed by the conveyor belt by irradiating the book with ultraviolet rays. The above disinfecting apparatus is configured so that the entire surface of the book can be irradiated with ultraviolet light by devising the arrangement of the germicidal lamp.

[0004]

In the method of sterilizing by irradiating ultraviolet rays as described above, it is possible to sterilize only the surface of a book which can be irradiated with ultraviolet rays.
On the other hand, a book is configured by holding a large number of content sheets between cover sheets. Therefore, the conventional sterilization apparatus cannot be said to sterilize the entire book. Moreover, the book's fortune,
Many irregularities are formed on the top, the ground, and the like by the edges of the above-described content paper. For this reason, it is substantially difficult to irradiate the entire surface with ultraviolet rays.

[0005] Furthermore, in the disinfection apparatus described in the above-mentioned publication, ultraviolet light must be applied to each conveyed book one by one, and a large number of used books cannot be sterilized at the same time. Therefore, it cannot be said that work efficiency is good.

In order to solve the above problem, it is conceivable to use a sterilizing apparatus using a sterilizing gas used in hospitals and the like. However, since a book has a structure in which a large number of content sheets are stacked between cover sheets, it is difficult to infiltrate a sterilizing gas into gaps between the content sheets in a short time. On the other hand, if a highly reactive sterilizing gas is applied to a book for a long time, the paper may be deteriorated. For this reason, it is required that the sterilizing gas is permeated into the book in a short time. In addition, the above-mentioned hospital equipment becomes large-scale, and it is difficult to install it in a secondhand bookstore.

[0007] It is an object of the present invention to solve the above problems and to provide a book sterilizing method and a sterilizing apparatus capable of sterilizing the entire book including the content paper.

[0008]

Means for Solving the Problems To solve the above problems, the present invention takes the following technical means.

The invention described in claim 1 of the present application relates to a book sterilization method for sterilizing a book housed in a sterilization container by causing a sterilizing gas to act while flowing the book.

[0010] In a book, when the cover is closed, the inner sheets are overlapped with each other, so that sterilizing gas cannot be applied to the inside of the book in a short time. In order to solve this problem, according to the invention described in this claim, a sterilizing gas is caused to act on a book while flowing it.

As a means for flowing the sterilizing gas, the sterilizing gas can be caused to directly spray from a storage tank or a generator to a book, or the sterilizing gas can be circulated and flown by a fan or the like disposed in a sterilizing container. Can also.

[0012] Utilizing the flow pressure generated by flowing the sterilizing gas, the gap between the sheets in the book is
The sterilizing gas can be permeated in a short time, and the sterilizing effect can be enhanced. Further, since a large number of books can be accommodated in the sterilization container and sterilization can be performed at once, the working efficiency is high.

According to the second aspect of the present invention, sterilization is performed by flowing a sterilizing gas toward at least one of a fore edge, a top, and a ground of a book in a sterilizing container.

In the fore-edge, top, and ground portions, since the edge of the content paper is exposed, the sterilization gas is caused to flow toward this portion so that the sterilization gas flows into the gaps between the stacked content papers. Can work. According to this method, it has become possible to cause the sterilizing gas to sufficiently act on the turned-up portion or the like touched by the user's finger.

[0015] The invention described in claim 3 of the present application is to irradiate ultraviolet rays in addition to the sterilization by the sterilizing gas. Ultraviolet rays have a strong bactericidal effect and have an immediate effect. The ultraviolet rays are irradiated toward the inner space of the sterilizing container and / or the surface of the book.

By irradiating the book surface, the book surface can be directly sterilized. This makes it possible to effectively sterilize the outer surface of the book, such as the cover, which is often touched by the fingers.

On the other hand, in the present invention, dust such as paper dust is circulated in the sterilizing container in order to flow the sterilizing gas. For this reason, by irradiating the interior space of the sterilization container with ultraviolet rays, it becomes possible to effectively sterilize the microorganisms adhering to the dust in cooperation with the sterilization gas.

According to a fourth aspect of the present invention, sterilization is performed by applying a sterilizing gas while oscillating or vibrating a book stored in a sterilizing container. The book has a structure in which the content paper is held between the covers via a spine portion. For this reason, by swinging or vibrating the book, the gap between the content sheets is changed, and the penetration of the sterilizing gas between the content sheets is promoted.

The mode of swinging or vibrating is not particularly limited. The entire book can be swung or vibrated as a single unit so as to provide the same effect as flowing sterilizing gas, or each content sheet can be directly swung so as to change the interval between the content sheets. Can also.

According to a fifth aspect of the present invention, sterilization is performed while the front and back covers and / or each content sheet of the book are relatively rocked or vibrated in the sterilization container. For example, the sterilizing gas can be made to act while swinging each content sheet so as to turn it. When the cover or the contents of the book is relatively swung, the gap between the contents changes. Thereby, penetration of the sterilizing gas between the respective sheets can be promoted, and the sterilizing effect can be remarkably enhanced. In addition, the sterilization time can be significantly reduced.

The method of oscillating or vibrating is not particularly limited. The oscillating or oscillating method may be such that the oscillating or oscillating operation can be performed continuously by using the power of a motor or the like, or the shelf or the like holding the book is manually intermittently oscillated. It can be configured to be. It is desirable to swing or vibrate while holding the book so that the cover or each content sheet can relatively swing or vibrate in the book holding means.

According to a sixth aspect of the present invention, the cover or the contents of a book is swung by utilizing the flow of the sterilizing gas. For example, when a sterilizing gas is blown onto the content sheets in a state in which the cover is opened at a predetermined angle, each content sheet is swung so as to be turned up by the flow pressure of the sterilization gas. As a result, the sterilizing gas can be permeated between the content sheets of the book.

According to a seventh aspect of the present invention, a sterilizing gas is applied to a book while changing the pressure in a sterilizing container filled with the sterilizing gas.

Since a book is made of porous paper, the ratio of voids is high. Also, there is a certain gap between each of the content sheets. Therefore, the outer pressure fluctuation directly changes the pressure in the gap and the gap. The invention described in this claim utilizes the above principle,
The sterilizing gas permeates the inside of the book.

Since the sterilizing gas in the sterilizing chamber permeates into the book as the pressure fluctuates, the book can be sterilized efficiently. The degree of pressure change is not particularly limited. By repeating the fluctuation, several tenths of the atmospheric pressure
A degree of variation is sufficient. Also, the range of the fluctuation is not limited, and can be changed around the atmospheric pressure.
It can be varied in a range higher or lower than the atmospheric pressure. Further, the mode of the pressure fluctuation is not particularly limited. The fluctuation period can be set to be short and the vibration can be changed, or the fluctuation period can be set to be long.

According to the invention described in claim 8 of the present application, the book is swung in the sterilizing container and the gas is operated while flowing the sterilizing gas. This is a combination of the above-described claim 1 and the invention described in claim 4, and the sterilization efficiency can be further increased, and a sufficient effect can be obtained in a short time.

According to a ninth aspect of the present invention, there is provided a book sterilizing method in which a sterilizing gas is applied to a book in a sterilizing container accommodating the book, wherein the sterilizing container having been sterilized is opened before opening the sterilizing container. Or to reduce the concentration of the sterilizing gas.

When storing or removing a book in a sterilization container, it is necessary to open the lid of the sterilization container and open the internal space of the sterilization container to the atmosphere. At this time, if the sterilizing gas is present in the sterilizing container, the sterilizing gas leaks out. On the other hand, some of the sterilizing gases applicable in the present invention have a concentration that has a sterilizing effect and has a bad effect on the human body. The invention described in this claim is to prevent the sterilizing gas from leaking out of the sterilizing container.

The method for removing the sterilizing gas is not particularly limited. It can be discharged outside the room so as not to affect the operator, or can be temporarily evacuated to a gas tank or the like prepared in the apparatus. Further, by neutralizing, the substance can be converted into a substance harmless to the human body and then discharged to the outside air. In the method of evacuating to a gas tank, etc.,
It is economical because sterilizing gas can be reused.
The concentration of the sterilizing gas may be reduced or neutralized so as not to adversely affect the human body.

According to a tenth aspect of the present invention, a plurality of sterilizing containers are provided, and the sterilizing gas in the sterilizing container having been sterilized is retracted to another sterilizing container.

If the sterilization operation is performed in only one sterilization container,
Work efficiency becomes poor. In particular, when the sterilizing gas to be used has to be discharged outside the room or the like, the working time also increases. The invention described in the present claim is to provide a plurality of sterilizing containers and perform a sterilizing operation while moving a sterilizing gas between the sterilizing containers. By transferring the sterilizing gas filled in the sterilizing container open to the atmosphere to another sterilizing container, there is no waste of the sterilizing gas. In addition, since the sterilization operation can be performed continuously, the operation efficiency is significantly improved. In addition, since the pressure in the sterilization container where the sterilizing gas has been evacuated changes, the sterilizing effect is also improved.

[0032] The invention according to claim 11 of the present application comprises a sterilizing step of applying a sterilizing gas to a book in a sealed container, an aroma adding step of applying an aromatic gas or a deodorant gas to the book in the container, or It includes a deodorizing step.

In a book to be recycled, not only microorganisms but also bad smells such as a musty smell may be present. Further, by applying a sterilizing gas or neutralizing the sterilizing gas, an unpleasant odor may be added or may remain. For example, when formalin gas is used as a germicidal gas, it is often neutralized with ammonia, but if the amount of ammonia to act on is too large, an ammonia odor may remain in books. The present invention removes not only the microorganisms attached to the recycled books but also the above-mentioned bad smell and promotes the recycling of the books.

Since the sterilizing gas and the aromatic gas can act in the same container, the working efficiency is improved. In particular, by causing an aromatic gas or a deodorant gas to act on a book in the same manner as the sterilizing gas according to the first to tenth aspects of the present invention, it is possible to permeate the contents of the book.

By performing the sterilization step, the aroma treatment step, or the deodorization step, the commercial value of the recycled book is significantly increased, and the recycling market can be expanded.

The type of the sterilizing gas according to the present invention is not particularly limited, but it is desirable to select a gas that is easy and safe to handle. For example, as described in claim 12, one sterilizing gas selected from ozone gas, ethylene oxide gas, chlorine gas, and formalin gas can be adopted as the sterilizing gas.

[0037] The invention according to claims 13 to 25 of the present application relates to an apparatus for performing the above-described sterilization method.

According to a thirteenth aspect of the present invention, there is provided a sterilizing container for storing a book, a sterilizing gas generating means for storing or generating a sterilizing gas and filling the sterilizing container with the sterilizing gas.
The present invention relates to a sterilization apparatus including a book holding means for holding the book in the sterilization container, and a sterilization gas flowing means for flowing the sterilization gas in the sterilization container.

The material, form, size, and the like of the sterilizing container are not particularly limited, and the sterilizing container may be formed so as to house a book and allow a sterilizing gas to act in a closed state. In addition, it is desirable that the book can be easily put in and taken out and that the sterilizing gas does not leak out.

The sterilizing gas generating means can be selected according to the type of gas to be employed. For example, ozone gas, chlorine gas and the like can be configured by providing a known sterilizing gas generator in a sterilizing device. On the other hand, ethylene oxide gas or the like which cannot be easily generated can be used while being kept in a tank at a high pressure or in a liquid state, and filled in the sterilization container as needed. Also,
The germicidal gas generating means includes a known gas adjusting device such as a concentration adjusting device for adjusting the concentration of the germicidal gas and a pressure adjusting device for adjusting the pressure.

Although the form of the book holding means is not particularly limited, it is preferable that the book holding means be held at least in such a manner that the cover or each of the contents can be relatively swung. For example, when books are set up one by one and held with a certain gap between adjacent books, the cover and each content sheet can swing. On the other hand, in a state where books are stacked horizontally, the weight of the upper book acts on the book located below and the swinging of the cover and the content paper is hindered. It becomes difficult.

The germicidal gas flowing means applies the germicidal gas evenly to the stored books, or makes the germicidal gas flow so that the germicidal gas easily permeates between the contents of the books. For example, a circulation fan may be provided in the sterilization container so that the sterilizing gas acts uniformly on a plurality of stored books, or the sterilizing gas may be blown out toward a small opening of the book.

According to a fourteenth aspect of the present invention, as the germicidal gas flowing means, the germicidal gas filled in the germicidal container is circulated while being circulated to at least one of the fore, heaven, and the ground of the book. It employs a circulating fluidizing device that makes it flow toward.

The circulating fluidizing device includes, for example, a fluidizing fan for flowing a sterilizing gas,
It can be configured to include a flow direction control member directed to the top and the ground.
As the flow direction control member, a plate-like member, a blow duct, or the like that can regulate the flow direction of the sterilizing gas can be employed. The edge of the content paper is laminated on the edge, top, and ground of the book in an exposed state, and sterilization gas is allowed to permeate the gaps between the content papers in a short time by flowing sterilization gas toward this part. It is possible to do.

Although the flow rate of the sterilizing gas is not particularly limited, it is preferable that a certain flow pressure is applied to the small edge of the book so that the sterilizing gas permeates into the gap between the sheets. .

The invention described in claim 15 of the present application is provided with an ultraviolet irradiation device for irradiating the inside space of the sterilization container and / or the surface of the book with ultraviolet light.

Ultraviolet rays have not only a strong germicidal activity but also an immediate effect. Also, the most dirty of the recycled books are the outer surfaces such as the cover and the fore edge. Therefore, by irradiating the surface of the book stored in the sterilizing container with ultraviolet light, the sterilizing operation can be performed efficiently in cooperation with the sterilizing gas.

On the other hand, in the present invention, since the sterilizing gas in the sterilizing container is caused to flow, dust such as paper powder of a book is also caused to flow in the sterilizing container. Therefore, by irradiating the interior space of the sterilization container with ultraviolet rays, the microorganisms adhering to these dusts can be effectively sterilized.

[0049] The invention described in claim 16 of the present application is a sterilizing container for storing a book, a sterilizing gas generating means for storing or generating a sterilizing gas and filling the sterilizing container with the sterilizing gas.
The present invention relates to a sterilization apparatus including a book holding means for holding the book in the sterilization container, and a rocking means for rocking the book in the sterilization container.

The sterilizing container and the sterilizing gas generating means include:
The same thing as the above-mentioned invention can be adopted. The rocking means may be configured to rock each book as a whole, or may be configured to rock the cover portion or the content sheet of each book relatively. Further, the meaning of the swing of the present invention includes the concept of vibration, and the swing may be performed at a visible speed with a large amplitude, or may be performed with a small amplitude and a high speed. .

For example, a swing device for swinging the book holding means can be employed as the swing means. By swinging the book holding means, the accommodated book is swung integrally with the gas filled in the sterilization container, or each of the content sheets is relatively swung. As a result, penetration of the sterilizing gas into the space between the content sheets is promoted.

Further, as in the invention as set forth in claim 18, a swinging device for directly swinging the book held by the book holding means can be adopted as the swinging means. For example, it is possible to hold the book with the cover open at a predetermined angle, and to oscillate the contents by turning the inside of the book by blowing the sterilizing gas in the sterilizing container onto the small edge of the book. Since the sterilizing gas can be applied directly to the surface of each content sheet, the entire book can be reliably sterilized.

The book holding means supports at least one of the front cover, the back cover, and the spine of the book in order to promote at least the swing of each of the content sheets. It is desirable to provide a cover holding unit. Generally, since each cover portion of a book has a higher strength than the content paper, the book can be reliably held while allowing the content paper to swing. For example, the above-described cover holding portion is configured to include a bottom wall portion for holding a spine of a book and a side wall portion for holding the front and back covers with a predetermined angle opened, and to hold the book with the fore edge facing upward. Can be configured to hold. As a result, the book can be reliably held in a state where the content paper can swing.

The germicidal gas neutralizing means serves to harmlessly sterilize the germicidal gas held in the germicidal container or the book and discharge the germicidal gas when the employed germicidal gas is toxic. For example, when formalin gas is used as the sterilizing gas, ammonia gas generating means can be used. When ozone gas is used, a device for irradiating ultraviolet rays having a wavelength that decomposes ozone gas can be provided.

The germicidal gas evacuation means is provided in claim 2 of the present application.
As in the invention described in 2, it is possible to provide a gas tank for retracting the sterilizing gas in the sterilizing container. For example, when opening the sterilization container, the sterilization gas is sucked and temporarily evacuated to the gas tank. By providing the sterilizing gas evacuation means, the sterilizing gas does not leak out when the book is taken in and out, and the safety is improved.

The neutralization and evacuation of the sterilizing gas may be performed by lowering the sterilizing gas to a concentration that is safe for the human body.
It is not necessary to completely neutralize or evacuate. In the case of a sterilizing gas which is safe for the human body at a concentration having a sterilizing effect, it is not necessary to provide the sterilizing gas.

The invention according to claim 23 of the present application provides a plurality of sterilizing containers for accommodating books, a sterilizing gas generating means for storing or generating sterilizing gas and filling the sterilizing container with the sterilizing gas, And a gas transfer device for retracting the sterilizing gas from one of the sterilizing containers into another sterilizing container.

By providing a plurality of sterilization containers, it is possible to perform a continuous sterilization operation, and the operation efficiency is improved. Further, a sterilizing container to be sterilized can be used as a sterilizing gas evacuation unit, and the sterilizing gas can be used efficiently. Also, there is no need to provide a separate evacuation gas tank. Various gas transfer devices such as an air pump can be adopted as the gas transfer device.
Further, by moving the sterilizing gas, the pressure in the sterilizing container for performing the sterilization is changed, so that the sterilizing effect is enhanced.

[0064] The invention described in claim 24 of the present application is a sterilizing container for accommodating a book, a sterilizing gas generating means for storing or generating a sterilizing gas and filling the sterilizing container with the sterilizing gas.
Book holding means for holding the book in the sterilization container,
The present invention relates to a sterilizing apparatus including an aromatic gas generating means or a deodorizing gas generating means for storing or generating an aromatic gas or a deodorizing gas and filling the sterilizing container.

The sterilizing container, the sterilizing gas generating means, and the book holding means can be the same as those described in the above claims, and therefore the description is omitted.

As the means for generating an aromatic gas or a deodorant gas using the above-mentioned aromatic gas generating means or deodorant gas generating means, those having the same constitution as the above-mentioned sterilizing gas generating means can be adopted. That is, it is sufficient to store or generate the aromatic gas or the deodorant gas and fill the sterilizing container. In addition, since the same device and method as that for applying a sterilizing gas to a book can be employed as it is, it is possible to add fragrance to the book content paper.

Various known scent gases can be used as the scent gas. Further, the deodorant gas can be employed for the purpose of removing not only the odor attached to the book but also the odor of the residual sterilizing gas or the odor of the neutralizing agent.

According to the invention described in claim 25 of the present application, a sterilizing gas selected from ozone gas, ethylene oxide gas, chlorine gas and formalin gas is used as the sterilizing gas.

In the above-described embodiment, the case where only the sterilizing gas is applied to the book is described. After the sterilizing operation is completed, the aromatic gas or the deodorant gas is applied to the book in the same manner as the sterilizing gas. It is also possible to add an aroma or deodorize a book. The said aromatic gas generator or deodorant gas generator can be comprised similarly to the said sterilization gas generator. Further, after the sterilization step is completed, the sterilizing gas and the air may be replaced, and the air may act similarly to the sterilizing gas, thereby removing the sterilizing gas remaining inside the book. .

In the first embodiment, the book shelf-shaped book holding shelf 7 is provided to swing the book. However, the present invention is not limited to this, and the book can be swung in various modes. Can be held. For example, as shown in FIG.
The book can be held by holding the hanging hook 51 between the middle portions of the content paper 20 of the book 6 with the fore-edge facing downward.

The hanging hook 51 has a base end 52 swingably connected to a ceiling or a frame member of a sterilization container, and swings the book content paper in the same manner as in the first aspect of the present invention. Can be held as possible.

Further, in the embodiment, the book is configured to swing automatically, but it may be configured to swing manually.

Further, as another method for rocking or vibrating the book, air vibration such as sound waves can be used. For example, a book can be vibrated by generating low frequency air vibrations of relatively large amplitude in a sterilization container. Further, the above-mentioned vibration can be transmitted to the gap space between the content sheets to promote infiltration of the sterilizing gas.

The sterilizing apparatus according to the present invention is a sterilizing apparatus suitable for sterilizing a book. However, articles made of a porous material, such as a book, into which sterilizing gas is unlikely to enter, or a large number of articles, are provided. It is also suitable for sterilizing an article formed by laminating the above sheet materials. For example, it can be applied to sterilization of clothing and the like.
