Description

  The present invention relates to an automatic library, and is characterized by having an apparatus capable of maintaining a good storage environment inside and around the rack.

  The automatic library has a rack for mainly storing documents. If necessary, the target document can be taken out from the rack, and used documents can be stored in the rack. Most of the material of documents stored in the automatic archive is paper, and it is important to keep the environment inside and around the automatic archive, particularly humidity and temperature, in order to keep the preservation state good for many years.

  In the automatic library, air does not easily flow through the rack portion for storing the documents, and the air around the rack portion is stagnant. As the air stagnates, heavy, humid air accumulates at the bottom of the rack and dry air accumulates at the top of the rack. Therefore, the documents stored in the lower part of the rack are deteriorated due to moisture, or deteriorated earlier due to dampness and soot caused by moisture.

  In order to prevent the deterioration of the document due to the environmental conditions as described above, the indoor environment in which the automatic warehouse is installed is adjusted by an air conditioner. However, even if the environment of the entire room is adjusted with an air conditioner, the conditioned air does not reach every corner of the rack, and the effects obtained by providing the air conditioner are limited. An automatic library is often installed in the lower part of a building, for example, in the basement, and has a problem of high humidity and easy occurrence of soot.

  As a prior art related to the solution of the above problem, there is a container environment improvement device described in Patent Document 1. The invention described in Patent Document 1 includes an air duct having an air supply path and an intake path, and an air purifying means for purifying air sucked from the intake path. The plurality of air inlets sucks air that has been supplied from the plurality of air inlets and has traveled around the housing (corresponding to the rack) into the air duct. The air cleaning means purifies the intake air, and the plurality of air supply ports supply the purified air to the outside of the air duct.

  Embodiments of an automatic library according to the present invention will be described below with reference to the drawings.

  1 to 3, an automatic library 100 is constructed in the building 1. The automatic warehouse 100 includes a rack 2 having a plurality of container storage spaces 3 in which a plurality of containers 9 can be stored. The rack 2 is divided into a plurality of parts in the vertical direction and the horizontal direction, so that a plurality of container storage spaces 3 are formed. The racks 2 are constructed with two racks 2 as a set, and a space necessary for the stacker crane 5 to enter and exit between the set of racks 2 is provided between the sets of racks 2. .

  A container 9 is stored in each container storage space 3. Each container 9 can store a plurality of graphic documents 15 (see FIG. 4). In addition to general books and magazines, pictorial documents include old documents, bags and boxes that contain letters, etc. Each container storage space 3 may store one container 9, but as shown in FIG. 3, the container storage space 3 stores two containers 9 in the depth direction of the container storage space 3. There may be.

  The stacker crane 5 can enter and exit from the set of racks 2 by traveling along the rails 51 laid between the set of racks 2. The stacker crane 5 enters between the pair of racks 2 and can travel along the front surface of the racks 2 and can be raised and lowered. The stacker crane 5 has a transfer device 52 that can transfer the container 9 to and from the rack 2.

  When the stacker crane 5 travels to one travel limit position, the stacker crane 5 reaches a position where it has left the pair of racks 2. The loading / unloading rack station 11 is arranged corresponding to the position of the stacker crane 5 at this time. The incoming / outgoing rack station 11 is divided into an incoming rack station on the upper side and an outgoing rack station on the lower side. When the container 9 is stored, the transfer device 52 of the stacker crane 5 transfers the container 9 between the stacker crane 5 and the storage rack station. When unloading the container 9, the transfer device 52 of the stacker crane 5 transfers the container 9 between the stacker crane 5 and the unloading rack station.

  In the illustrated embodiment, two sets of racks 2 are constructed, and two stacker cranes 5 are provided corresponding to the two sets of racks 2. Two loading / unloading rack stations 11 are provided corresponding to the two stacker cranes 5.

  Each loading / unloading rack station 11 transfers the container 9 to / from the loading / unloading cart 12. The entry / exit cart 12 is divided into an entry cart on the upper side and an exit cart on the lower side. The loading / unloading cart 12 travels between the two loading / unloading rack stations 11 and the horizontal conveyance conveyor 13, and the container 9 can be transferred between the horizontal conveyance conveyor 13 and the loading / unloading cart 12. The horizontal conveyance conveyor 13 is also divided into an upper side for entry and a lower side for exit.

  The horizontal conveyor 13 extends to the vicinity of the depositing / dispensing station 20, and the container 9 can be transferred to and from the vertical conveyor 14 near the depositing / dispensing station 20. In the case of delivery, the vertical conveyance machine 14 conveys the container 9 from the bottom to the top, and the container 9 is conveyed toward the depositing / dispensing station 20 by a horizontal conveyance device. In the case of warehousing, the vertical conveyor 14 conveys the container 9 conveyed from the depositing / dispensing station 20 from top to bottom.

  The configuration and operation of the automatic archive 100 described so far are not significantly different from those of known automatic archives. Hereafter, the characteristic part as an Example of the automatic library which concerns on this invention is demonstrated.

  One of the features of the automatic library 100 shown in FIGS. 1 to 4 is that it has a humidity control device. The humidity control apparatus adjusts the humidity environment around the rack 2, and includes a humidity controller 4, a blower duct 6 and an intake duct 7 provided in the rack 2. The humidity controller 4 has a heater that adjusts the humidity of the air taken in from the intake duct 7 and warms the air.

  In the example shown in FIG. 1, a humidity control device including a humidity controller 4, a blower duct 6, and an intake duct 7 is provided for each rack 2. As described above, the stacker crane 5 enters between the set of racks 2, and the set of racks 2 is composed of two racks. A dampening device is provided. The air duct 6 is disposed at the bottom of the rack 2. As shown in FIG. 4, the distance d between one rack 2 and another rack 2 adjacent thereto is narrow, and this narrow space is not a travel space for the stacker crane 5. The air duct 6 and the air intake duct 7 are arranged in the narrow space. Air naturally flows from the bottom to the top in the space d. The portion of the distance d can be regarded as a kind of duct.

  Each air duct 6 is arranged at the lower end of the rack 2 in parallel with the traveling direction of the stacker crane 5. Each air duct 6 is provided with a plurality of air outlets 61 (see FIG. 4) upward and at regular intervals in the length direction of the air duct 6. The air that has been conditioned by the humidity controller 4 and heated by the heater is guided to the air duct 6 and is sent upward from the air outlet 61.

  An intake duct 7 is arranged in parallel with each air duct 6 above each air duct 6 and slightly above the rack 2 in correspondence with each air duct 6. On the lower surface side of each intake duct 7, a plurality of intake ports 71 are provided at regular intervals in the length direction of the intake duct 7. The air blown out from the air blowing port 61 rises along the front surface of the rack 2, is sucked from the air intake port 71, and is guided to the air intake duct 7.

  An air circulation path is formed in the order of the humidity controller 4, the air duct 6, the air outlet 61, the air inlet 71, the air intake duct 7, and the humidity controller 4. The pressure when air is blown out from the air outlet 61 may be minute, and the air flow from the air outlet 61 on the lower side toward the air inlet 71 on the upper side is generated in a state close to natural convection. The air from the blower port 61 toward the intake port 71 is conditioned by the humidity controller 4 and further heated and circulated. Therefore, even if there is air with high humidity under the rack, the humidity is adjusted while circulating, and the entire rack 2 is adjusted almost uniformly to a desired humidity.

  The air outlet 61 is basically disposed at the bottom of the rack 2. The intake port 71 only needs to be above the blower port 61. The intake port 71 may be in the middle of the rack 2 in the height direction as shown in FIG. It is possible to select a case where a valve is provided in the intake duct 7 to enable the function of the intake port 71 at the upper end of the rack 2 and a case where the function of the intake port 71 in the middle of the height direction is enabled. It may be. Furthermore, the temperature sensor or the temperature / humidity sensor 8 is arranged corresponding to the arrangement position of the intake port 71, and the conditioned air is concentrated from the detection signals of these sensors in the part where the environmental condition is deteriorated. You may make it circulate. Thereby, useless operation of the humidity control apparatus can be eliminated, and useless power consumption can be eliminated.

  When the intake port 71 is provided in the middle in the height direction of the rack 2 or the function of the intake port 71 in the middle in the height direction is made effective by the valve, the environment below the rack 2 is It can be improved to the same extent as the environment in the middle of the height direction. Further, it is possible to intensively improve the environment below the rack 2 where the environmental conditions tend to be worse.

  By arranging the air outlet 61 in the lower part of the rack 2, the environment in the lower part of the rack 2 having the worst environmental conditions can be intensively improved.

  As shown in FIG. 3, the rack 2 is installed with its bottom raised from its installation surface. The amount of raising the bottom is preferably 300 mm or more. Since moisture tends to accumulate at the bottom of the rack 2, the environmental conditions are not good for storing graphics. Therefore, the rack 2 is raised so that no document can be stored near the bottom of the rack 2 having poor environmental conditions.

  As shown in FIG. 3, a camera 10 is attached to the stacker crane 5. The camera 10 is attached to a transfer device 52 or the like that moves along the front surface of the rack 2 so that each container storage space 3 of the rack 2 can be photographed. Moreover, the camera 10 is equipped with the lighting fixture. Thereby, even if the inside of the rack 2 is dark, the inside of the container 9 can be clearly confirmed. The lighting fixture may be a black light or a penlight having directivity in the irradiation direction. Furthermore, it is possible to expedite discovery of the moth by using a lighting device with high saturation and a light color of daylight, or by using an LED chip that emits light in the UV region.

  In each rack 2, a plurality of temperature / humidity sensors 8 are arranged substantially evenly so that the temperature / humidity distribution of the entire storage space 3 of the container can be measured. The temperature and humidity measurement data from each temperature and humidity sensor 8 is input to the humidity control PC 35 (see FIG. 5) one by one. The humidity control PC 35 determines whether or not the detection value by each temperature and humidity sensor 8 is within a predetermined range. The predetermined range is a range in which it can be determined that the environment around the rack 2 has deteriorated. When the system manager 34 determines that the temperature is within the predetermined range, the system manager 34 moves the stacker crane 5 to the container storage space 3 in which the temperature / humidity sensor 8 is installed, and displays an image of the container storage space 3. Take a picture with the camera 10.

  An image captured by the camera 10 may be a still image or a moving image. Alternatively, the ID of the container 9 stored corresponding to the image may be listed at the same time as the image of each container storage space 3 is taken and transmitted to the administrator together with the image data. By obtaining an image and ID of a place where it is determined that the environment in the rack 2 is bad from the detection value by the temperature / humidity sensor 8, it is possible to more accurately determine whether the environment in the rack 2 is good or bad. For example, when it is determined from the detected value by the temperature / humidity sensor 8 that the environment is not strange even if wrinkles grow, it can be confirmed by checking the photographed image and the ID of the container 9 whether or not wrinkles actually grow. it can. When the ID of the photographed image container 9 is seen and it is found that the stored document is in a situation where, for example, wrinkles grow, the container 9 storing the document is changed to another container. Move to storage space or transport to banking station. The operation control as described above is performed by the system manager 34 or via the system manager 34.

  In addition, by configuring as follows, it is possible to more effectively prevent deterioration due to environmental conditions of a document that is a stored item. That is, by having a plurality of empty rack spaces in the rack accommodating space in advance, the system manager 34 configures a control system so as to control the movement of the stacker crane 5 with the output signal of the temperature / humidity sensor 8 as an input. To do. More specifically, the system manager 34 stores movement history information of each container 9. Then, the system manager 34 issues a command to the stacker crane 5 so as to move the container 9 that has not moved for a certain period of time from the detection value of the temperature / humidity sensor to another container storage space 3 with good environmental conditions.

  According to said structure, since the document stored in the place where environmental conditions are bad can be moved to the place where environmental conditions are good, degradation of the documents by environmental conditions can be suppressed.

  The output of the humidity controller 4 is changed according to the detection value of the temperature / humidity sensor 8. Such control of the humidity controller 4 is performed by the humidity control PC 35.

  An example of the control system of the embodiment of the automatic archive described above will be described. In FIG. 5, the automatic library 100 includes the rack 2, the container 9, the camera 10, the stacker crane 5, the depositing / dispensing station 20, and the system management machine 34. The automatic library 100 also includes a main control device 30, an interface PC 33, a first work PC 31, another work PC 32, a transfer machine 30, a cashier station conveyor 21, and another cashier station conveyor 22. The conveyor 30 includes the storage / removal cart 11, the vertical conveyor 14, and the like.

  As can be seen from FIG. 5, there are a plurality of humidity controllers 4 and a plurality of temperature and humidity sensors 8. The humidity controller 4 and the temperature / humidity sensor 8 are connected to a humidity control PC 35, and the humidity control PC 35 is connected to the PCs 33, 31, and 32 in addition to the system manager 34. The PCs 33, 31 and 32 are connected to the main control unit 30. Connected to the main control unit 30 are a camera 10, a stacker crane 5, a transporter 30, and a depositing station conveyors 21 and 22.

  The humidity control PC 35 determines the humidity control operation most suitable for each rack 2 based on the detection values of the temperature / humidity sensors 8 arranged at various locations of the rack 2. Furthermore, based on the above determination, the operation of the humidity controller 4 of each rack 2 is controlled.

  The humidity control PC 35 interposed between the humidity controller 4, the temperature / humidity sensor 8, and the system manager 34 may be replaced with a distribution board. The distribution board controls the operation of the humidity controller 4 which is an environment improvement device based on the detection signal of each temperature / humidity sensor 8. That is, based on the detection signal of the temperature / humidity sensor 8 arranged in each place, control is performed so that the environment improvement device corresponding to each sensor is operated. The distribution board controls the operation of the environment improvement device based on the detection data of each temperature / humidity sensor 8 accumulated in the system manager 34.

  FIG. 6 shows an example of an operation for capturing an image of a specific container storage space 3 based on the detection signal of the temperature / humidity sensor 8 described above. First, the detection signal of the temperature / humidity sensor 8 is monitored to determine whether or not there is a portion where the environment of the rack 2 has deteriorated (S1). When it is found that there is a part where the environment is deteriorated, the stacker crane 5 is activated and moved to a part where the environment is deteriorated (S2). An image of a part where the environment is deteriorated is taken (S3), and the image data is transmitted to the system manager 34 (S4). The system manager 34 transmits the image data to the administrator's terminal (S5). Also, the container ID corresponding to the image data at that time may be transmitted at the same time. The administrator displays an image on the terminal, and determines the degree of deterioration of the document stored in the rack 2. When it is determined that the deterioration of the document is progressing, a measure such as moving the container 9 storing the document to the container storage space 3 in a favorable environment is taken.

  FIG. 7 shows an operation example when the container 9 is rotated when there is a container 9 that has not moved for a certain period of time. It is determined from the operation history stored in the system manager 34 whether there is a container 9 that has not moved for a certain period (S11). When it is determined that there is a container 9 that has not moved for a certain period of time, in order to move the container 9 to the container storage space 3 with good environment, the system management machine 34 determines the container storage space 3 with good environment (S12). ). The system manager 34 activates the stacker crane 5, controls its operation, moves the container 9 to the container storage space 3 with good environment (S13), and ends the operation. You may perform control which moves the container 9 containing a highly important book etc. to the container accommodation space 3 with favorable environment intensively. You may perform control which moves the container which entered the container storage space 9 with bad environment to the container storage space 9 with favorable environment for a fixed time.

  The operation of moving the container 9 to the container storage space 3 in a favorable environment is performed by controlling the operation of the stacker crane 5 with the system manager 34. A plurality of empty rack spaces are secured in the rack storage space in advance, and if the container storage space 3 with good environment is empty, the container 9 may be moved there. When the container 9 is stored in the container storage space 3 with good environment, the container 9 is taken out and moved to another container storage space 3, and the container storage space 3 with poor environment is stored in the empty container storage space 3. The container 9 moved from is stored.

  A plurality of empty rack spaces may be secured in the rack accommodating space in advance, and the container 9 storage priority may be set higher at the lower position than at the higher position. By doing so, an empty rack space can be naturally generated in the lower part of the rack 2 having a bad environment.

  In addition to the humidity control device provided in the rack 2, other environmental improvement devices may be provided in each rack 2 at regular intervals. Examples of environmental improvement devices include fans, heaters, and circulators. The control system is configured so that the environmental improvement device operates when the detected value of the temperature / humidity sensor arranged in each place of the rack 2 exceeds the reference value.

  A hole may be formed in the bottom of the container 9. By doing so, the air circulation in the container 9 can be improved, and in addition, the humidity control effect by the humidity controller 4 can be effectively exerted in the container 9.

  In the first embodiment, the air duct 6 is disposed at the bottom of the rack 2, the air intake duct 7 is disposed above the rack 2, the air outlet of the air duct 6 is provided upward, and the air naturally flows upward. On the other hand, in the second embodiment shown in FIG. 8, the air duct 6 is arranged not only at the bottom of the rack 2 but also at a plurality of locations in the height direction of the rack 2 with appropriate intervals. In the example shown in FIG. 8, the air duct 6 is arranged in three stages in the height direction of the rack 2. Two air ducts 6 are installed in the horizontal direction along each rack 2 adjacent to each other, two at each stage. Each air duct 6 is parallel to the traveling direction of the stacker crane.

  Each of the air ducts 6 is provided with a posture in which each air outlet 61 faces the corresponding rack 2, that is, a posture in which the air outlet 61 faces sideways. The air outlet 61 is a space generated below the container placement member 25 corresponding to the bottom of the container storage space 3 and above the storage drawing 15 of the container 9 positioned below the container placement member 25. Towards the resulting space. Therefore, the direction of the air passage 26 blown out from each air outlet 61 is a horizontal direction crossing the rack 2 in the front-rear direction (left-right direction in FIG. 8).

  In FIG. 8, the lowermost air duct 6 is provided with a blower port 61 sideways so that a wind passage 27 is generated in a space formed below the lowermost container storage space 3. The direction of the wind passage 27 is a horizontal direction that crosses the rack 2 in the front-rear direction, like the wind passage 26.

  In the second embodiment, the air blown out from each blower opening 61 of each blower duct 6 passes through the wind passages 26 and 27 below the container placement member 25 and flows naturally upward after crossing the rack 2. The air blown out from each blower port 61 is conditioned in the same manner as in the above-described embodiments and appropriately heated, so that the environment for storing the document is adjusted to a desirable environment.

  According to the automatic library according to the second embodiment, the wind blown out from the air duct 6 naturally flows upward across the rack 2, so that it does not directly hit the stored paper documents. There is no wind damage. In the case of natural convection of the wind coming out of the air duct 6, since the flow becomes weak when the wind reaches a certain height position, the air duct 6 is provided over a plurality of stages to compensate for the weak wind flow. .

  Part of the wind blown sideways from the air duct 6 flows upward from the gap between the container placement member 25 and the gap between the front and rear containers 9. Since the air flow between the containers 9 does not directly hit the document 15, the document 15 is not damaged by wind. Rather, the flow of air between the containers 9 brings about an effect of uniformly preparing the environment of each container storage space 3 of the rack 2. There is also an advantage that bacteria are less likely to adhere to the document 15 because the temperature and humidity are evenly flown over the entire rack 2.

  The space of the space | interval d which has arisen between the racks 2 which make a pair is a dead space. Since the air duct 6 is disposed outside the rack, that is, outside the rack 2 at both left and right ends in the example shown in FIG. 3, it is necessary to newly secure a space for disposing the air duct 6. Absent. In FIG. 8, reference numeral 8 denotes a temperature / humidity sensor.

  In the case where a plurality of air ducts are installed in a plurality of stages as in the second embodiment, if the air ducts are simply connected in series or in parallel, they are blown out depending on the position and location of the air duct. The strength of the wind changes.

  As shown in FIG. 9, the automatic warehouse according to the third embodiment includes a chamber 40 that compresses the air conditioned by the humidity controller 4. A plurality of air ducts 6 are connected to the chamber 40, and the air compressed in the chamber 40 is sent into the air ducts 6. The plurality of air ducts 6 are arranged in a plurality of stages in the height direction of the rack 2, similarly to the air duct 6 in the second embodiment.

  Assuming that the air pressure at the time of feeding from the chamber 40 to each air duct 6 is b1, b2, b3, b1 = b2 = b3, and the air pressure is uniformly applied to each air duct 6. Therefore, the air can be sent from each air duct 6 over the entire rack 2 without any unevenness, and the environment inside the rack 2 can be kept good.

  FIG. 10 shows a fourth embodiment. In many cases, microorganisms such as bacteria and mold adhere to the container 9 and the documents stored in the container 9. If a document with bacteria or mold attached is stored in the rack for a long period of time, the document is contaminated with bacteria or mold even though the environment inside the rack 2 is adjusted by the humidity controller. The A feature of the fourth embodiment is that a sterilizer for killing bacteria, molds, and the like is installed in the warehousing / conveying path of the document.

  In FIG. 10, Example 4 is provided with the rail 51 for the rack 2, the stacker crane 5, the container 9, and the stacker crane 5 similarly to the said Example. Reference numeral 50 denotes a stacker crane traveling passage formed between the racks 2. Reference numeral 111 denotes an incoming rack station, and reference numeral 112 denotes an outgoing rack station. The warehousing rack station 111 and the warehousing rack station 112 correspond to the warehousing rack station 11 in the first embodiment shown in FIG.

  In FIG. 10, the code | symbol 121 has shown the entering cart, and the code | symbol 122 has shown the leaving cart. The entry cart 121 and the exit cart 122 correspond to the entry / exit cart 12 in the first embodiment shown in FIG. Reference numeral 131 denotes a horizontal transfer conveyor for warehousing, and reference numeral 132 denotes a horizontal transfer conveyor for warehousing. Reference numeral 141 denotes a vertical transfer machine for warehousing, and reference numeral 142 denotes a vertical transfer machine for warehousing. Reference numerals 201 and 202 indicate the depositing / dispensing stations divided into upper and lower floors, and the depositing / dispensing stations 201 and 202 have work positions 203 and 204, respectively.

  In this way, the rack 2 and the depositing / dispensing station are connected by the warehousing / conveying route and the warehousing / conveying route. The configuration of the automatic warehouse according to the fourth embodiment shown in FIG. 10 is basically the same as the configuration of the automatic warehouse according to the first embodiment shown in FIG. Although not depicted in FIG. 10, the automatic warehouse according to the fourth embodiment includes the humidity control device, the air duct, and the air intake duct similar to the humidity control device, the air duct, and the air intake duct.

  The characteristic of Example 4 shown in FIG. 10 is that the sterilizer 70 is installed in the warehousing conveyance path | route by the horizontal conveyance conveyor 131 for warehousing. The sterilizer 70 includes an arch-shaped main body straddling the horizontal transport conveyor 131 in the width direction on the upper surface side of the horizontal transport conveyor 131, and an ion generator 75 attached downward to the lower surface of the main body. When the container 9 is received by the horizontal transfer conveyor 131, the container 9 passes under the ion generator 75. The document stored in the container 9 is irradiated with ions generated by the ion generator 75, and microorganisms such as bacteria and mold attached to the document are killed.

According to the fourth embodiment, the microorganisms attached to the document can be killed in the process of carrying the document to the rack, so that the container and the document in the container are stored in a favorable environment. Can do.
In addition, by applying ions from the ion generator 75 toward the document housed in the container from the upper part of the container 9, the document housed in the container can be uniformly sterilized.

  In addition, as the ion generator 75, what is generally called an ion cluster can be used. Instead of ion clusters, what are called plasma clusters can also be used.

  12 and 13 show Embodiment 5 of the automatic warehouse according to the present invention. Example 5 is characterized by including a microorganism sensor. The block diagram of the control system shown in FIG. 12 is obtained by adding a plurality of microorganism sensors 81 to the block diagram of the control system of the first embodiment shown in FIG. Further, the humidity control PC 35 in the control system of the first embodiment shown in FIG. 5 is replaced with a humidity controller / microorganism sensor control PC 351.

  Each microorganism sensor 81 is a sensor that detects the amount of microorganisms such as 1-10 μm mold fungus and bacteria floating in the air. The inside of the automatic warehouse is divided into predetermined areas, and a microorganism sensor 81 is arranged for each area. When the amount of microorganisms in a region to which at least one of the plurality of microorganism sensors 81 belongs becomes a certain amount or more, the microorganism sensor detects this and transmits a detection signal to the humidity controller / microorganism sensor control PC 351. The humidity controller / microorganism sensor control PC 351 determines the microbe sensor that has transmitted the detection signal, determines the region to which the microbe sensor belongs, and transmits information from the system manager 34 to the administrator. The contents of the information are that the microbial sensor is emitting a detection signal and its region.

  The system manager 34 may capture an area where the microbial sensor emits a detection signal with the camera 10 shown in FIG. 3 and display the captured image for the administrator.

  By incorporating a management program in the system manager 34, it is possible to perform autonomous management such as sampling inspection of a stored document stored in an automatic warehouse or delivery for cleaning. The sixth embodiment has incorporated such an autonomous management function, and the hardware may be the same as that shown in FIG.

[Sampling inspection]
The area of the rack 2 is divided into 20 areas, for example, and the microorganism sensor 81 is arranged in each area. The system manager 34 stores a program that determines the date and time of the sampling inspection, and performs sampling inspection from the detection signal of each microorganism sensor 81 on a daily basis according to the program. The order of extraction may be the order of arrangement of the regions or may be random. The sampling time interval may be determined arbitrarily. For example, the sampling time interval may be several minutes, several hours, or several days.

  A sample inspection may be performed from a range in which a detection signal from a microorganism sensor in an arbitrary region is confirmed by issuing a work command without a program by the system manager 34.

  As a result of the sampling inspection, if it is found that the microbial sensor emits a detection signal, the corresponding area is photographed by the camera 10 and the photographed image is displayed for the administrator as in the above-described embodiment. It may be. Alternatively, the containers in the corresponding area may be sequentially transferred to the depositing / dispensing station, and the containers and the stored drawing documents may be cleaned and stored.

[Cleaning delivery]
In the cleaning delivery, a program that defines the date and time of cleaning is stored in the system manager 34, the container is delivered to the delivery station according to the program, and the container and the stored drawing document are cleaned and entered. For the container that has been cleaned and stored and the stored drawing document, information to that effect is stored in the system manager 34.

  The delivery of the cleaning may be performed by an administrator issuing a work command without using a program by the system manager 34. Cleaning out may be performed in the order of the storage position in units of containers. Or you may carry out in order of the storage position of the container in a storage area in the said storage area unit.

[System Manager Functions]
FIG. 13 shows functional blocks of the system manager 34 in the sixth embodiment. As illustrated in FIG. 13, the system manager 34 includes a control unit 341, an inspection delivery unit 342, an environment response unit 343, and a communication unit 344.

The control unit 341 is a part that instructs various operations of the entire automatic library.
The inspection delivery unit 342 is a part for instructing delivery of the container to the delivery station in order to perform the sampling inspection and the cleaning delivery. The inspection delivery unit 342 instructs the control unit 341 to exit the container at the inspection date and time set in advance by an instruction from the work PCs 31 to 32 or by the operator's instruction. Receiving the container delivery instruction, the control unit 341 controls the operations of the stacker crane, the entry / exit rack station, the entry / exit cart, the horizontal transfer conveyor, and the vertical transfer machine, and transfers the container from the container storage space to the input / output station.

  The environment handling unit 343 is a part in which the humidity controller / microorganism sensor control PC 351 outputs an operation instruction signal corresponding to the detection signal to the control unit 341 based on the detection signal of the microorganism sensor. Upon receiving the operation instruction signal, the control unit 341 controls the operation of the humidity controller 4 or the sterilizer 70.

  When the temperature or humidity measured by the thermohygrometer 8 is a certain value or more, or when the amount of microorganisms measured by the microorganism sensor 81 is more than a certain value, the communication unit 344 This is the part that informs the administrator. The communication unit 344 may email the administrator from the humidity controller / microorganism PC 351. Further, a display may be used, and in that case, an appropriate PC display used in the automatic warehouse according to the present invention may be used in combination.
