In addition, the result of the work is automatically recorded as the work progresses. In this way, article entry / exit management is automated while minimizing computer terminal operations. Hereinafter, embodiments of the present invention will be described in detail for each example.

FIG. 1 is a schematic diagram illustrating an article access management system according to the first embodiment.
The article entry / exit management system 10 shown in the figure is used, for example, to pick up an article 12 from a warehouse in accordance with an instruction on an instruction slip. The article 12 is stored on a storage shelf 14 of the warehouse. A label 16 such as a barcode or an IC tag is attached to the article 12 or the storage shelf 14. The operator 11 operates the forklift 32 on which the pickup control device 34 is mounted to perform the pickup operation. A leader 18 is attached to the tip of the claw of the forklift 32. This reads the sign 16 attached to the article 12 or the storage shelf 14.

  The pickup control device 34 includes the above-described reader 18, a synthesized speech output device 20 that converts the read information into synthesized speech and outputs the synthesized speech, and a wireless device 21. The wireless device 21 wirelessly communicates with the headset 23 worn by the worker 11 to drive the speaker of the headset 23. The headset 23 is provided with a microphone, and the response sound of the worker 11 is received by the wireless device 21. A response recognition device 22 that recognizes the response of the worker 11 is connected to the wireless device 21. The response recognition device 22 has a function of generating the pickup recording data 27 by determining the content of the completed pickup work from the content of the response. The pickup control device 34 includes a registration device 24 that automatically registers pickup recording data 27 in the storage device 26. The pickup recording data 27 registered in the storage device 26 is then transferred and registered to a management server (not shown) at a predetermined timing through a network such as a wireless LAN. Data indicating the contents of the instruction slip 25 is also stored in the storage device 26.

  In the above system, since the reader 18 reads a bar code or an IC tag 16 attached to the storage location of the article 12 and converts it into a synthesized voice and outputs it, various operations can be performed without the operator looking at the display or the like. Can be smooth. In addition, there is an effect that work records can be automatically registered. The specific operation will now be described in detail.

  In the first embodiment, voice control is effectively used for warehouse management. The warehouse management database is stored in the management server 38. The operator 11 operates the forklift 32 to perform the entry / exit processing of the article 12. A pickup control device 34 is mounted on the forklift 32. The pickup control device 34 is connected to the management server 38 through the network 40. When the instruction slip is issued from the management server 38, the information is transferred to the pickup control device 34 through the network 40. The pickup control device 34 is controlled by a computer. The pickup control device 34 is provided with a synthesized voice output device 44 and a response recognition device 22. The synthesized voice output device 44 transmits synthesized voice wirelessly to the headset worn by the worker 11. The timbre can be freely changed to, for example, male or female.

  For example, when an instruction slip for shipping 10 articles 12 a is issued, the computer of the pickup control device 34 acquires the location where the 10 articles 12 a are stored with reference to the warehouse database of the server 38. Then, when the worker 11 inputs the number of the instruction slip, the computer synthesizes an instruction voice to the worker 11 “Please pick up 10 articles 12a stored in the MM area of the warehouse”. The worker 11 listens to the message synthesized by the headset 23. The worker 11 generates simple reserved words such as “yes”, “again”, and “no”. That is, the instruction slip 25 displays the type of article and the quantity of the article, and information indicating the storage location of the article is acquired from the warehouse database of the server 38 and the instruction is executed.

  This sound is input to the computer through the microphone of the headset 23. The response recognition device 22 of the computer compares the speech waveform pattern of the reserved word with the input speech waveform input pattern of the worker 11. When the operator 11 responds “Yes” to the instruction and recognizes it normally, for example, the computer outputs a message “Starting guidance”. The operator 11 starts a forklift 32 for pickup. The computer of the forklift 32 stores a storage location code indicating “MM area” and an identification code indicating the article 12 a in the storage device 26. This is registration data.

  The worker 11 moves the forklift 32 to a corresponding place and performs a pickup operation. The pickup control device 34 has the same function as the car navigation device. The pickup control device 34 acquires position information using a GPS device or a gyro sensor. The storage location code of the storage device 26 is read, and the moving direction of the forklift 32 is voice-guided with reference to the layout information of the warehouse. It is only necessary to indicate the traveling direction of the forklift 32 with an LED or the like. When the worker 11 cannot hear the message, a voice instruction such as “again” is returned.

  As a result, the message can be output from the pickup control device 34 again. When the voice instruction “system state” is returned, the system state can be output as a message such as “moving to pick up 10 articles 12a stored in the MM area”. Speaking of “time” reads the time, and speaking of “volume up” raises the volume. Thus, various states can be controlled and set by voice. By the guidance of the pickup control device 34, it arrives accurately in the shortest time before the shelf on which the article 12a in the MM area is placed. When the forklift 32 stops in front of the shelf, the message “There is an article 12a on the third shelf from the bottom” is output.

A bar code or an IC tag is attached to the article 12.
A bar code or an IC tag is also attached to the shelf on which the article 12 is placed. Sometimes nothing is attached. Hereinafter, an example in which a barcode is attached only to the article 12 will be described. A bar code reader (reader 18) is attached to the tip of the forklift 32. When the nail of the forklift 32 is brought close to the article 12 according to the message from the pickup control device 34, the barcode reading device reads the barcode of the article 12 and compares it with the identification code indicating the article 12a stored in the storage device 26. If they match, the message “yes” is output.

  At this time, the article 12 is picked up by the nail of the forklift 32. If they do not match, the message “No” is output. When the article 12 is picked up, a message “Have you picked up the article 12a?” Is output. If the worker 11 says “Yes”, a message “Did you pick up 10?” Is output. If the operator 11 says “No”, it waits for further pickup of the article 12a. If the operator 11 says “Yes” in response to the message “Did you pick up 10?”, The message “Work is finished” is output.

  At the same time, data indicating that ten articles 12a have been picked up are automatically registered in the database. The pickup recording data 27 stored in the storage device 26 is transferred and registered to the server 38 via the network 40 by the registration device 24. In the above processing, since the storage position of the article 12 and the pickup work can be confirmed by voice messages, the work of looking at the computer screen and the instruction slip is not required and the workability is improved. Errors can also be prevented. Conventionally, it has been necessary to read the barcode of the article 12 picked into the return box and inspect it again, but this system is no longer necessary, so the work efficiency can be greatly improved. In addition, if a word to be recognized is registered as a reserved word and it is similar to the voice pattern of the word, and it is determined that the word has been issued, the recognition process can be performed at high speed without error. Moreover, the learning process is not required regardless of the voice quality of the operator's voice. If at least the confirmation of the article, the confirmation of the quantity, and the confirmation of the type of work can be processed by voice, it becomes possible to control to omit key operations.

FIG. 2 is a schematic explanatory diagram illustrating an article access management system 10 according to the second embodiment.
In this example, the article 12 is stored in a storage box 29. The worker 11 takes out the article 12 using the handcart 30 and carries it. The operator 11 holds the reader 18 in his / her hand and scans the marker 16 attached to the article 12 for each take-out operation. The headset 23 and the reader 18 are controlled by a pickup control device 34. The pickup control device 34 includes a storage device 26 that stores an instruction slip 25 for an instruction to take out the article 12. In addition, a synthetic voice output device 20 is provided that converts at least the storage location of the article 12, the type of the article 12, and the quantity of the article 12 into a synthesized voice when the article 12 is taken out. The instruction slip 25 of the storage device 26 displays the type of article and the quantity of the article, and information indicating the storage location of the article is acquired from the warehouse database of the server 38. The contents of the instruction data including these are the same as those in the first embodiment. Other devices are the same as those in the first embodiment. That is, a response recognition device 22 that recognizes the response of the worker 11 and a registration device 24 that automatically registers the determined information in the storage device 26 or the server according to the recognition result are provided.

  When the article 12 is taken out from the storage location where the article 12 is stored, a confirmation sound is output, and the work can be performed while responding to the voice. Therefore, it is possible to reduce the work load while looking at the slip or the like. In addition, slip reading errors can be prevented. Furthermore, work records can be automatically registered. Specific examples are described in detail below.

  In this example, a handy pickup control device 34 is used. It is preferable that the pick-up control device 34 also incorporates a navigation system that guides the worker 11 to the article storage location. Then, for example, a two-dimensional barcode or IC tag attached to the article 12 is read. The pickup control device 34 may be automatically compared with an identification code indicating the article 12a stored in the storage device 26. The response content during the pickup operation may be the same as that of the forklift 32.

  To register a work report, proceed as follows. For example, when the work can be performed according to the instruction, the worker 11 inputs a voice such as “work completed” to the pickup control device 34. As a result, the registration device 24 operates to automatically generate pickup completion report data. Therefore, the operator 11 can start the next pickup process without being bothered by the reporting process. The contents of the registration data may be the same as in the first embodiment.

  A label sheet to be attached to a picked object can be printed by a mobile printer attached to the body. The mobile printer is integrated with the pickup control device 34. In this case, it is sufficient to input a voice “Label print”. Thus, a label to be attached to the article 12 picked up in the immediately preceding pickup operation can be printed. If two or more sheets are to be printed, the voice input may be “2 sheets” again. In this way, the pickup control device 34 automatically instructs and manages the work, and the data input work for the work report becomes unnecessary. In addition, when voice guidance is employed, it is not necessary to input data by touching the device, so that it is possible to perform hygienic work in a food factory, for example.

FIG. 3 is a schematic explanatory diagram illustrating an article access management system according to the third embodiment.
Here, an example in which the worker 11 transports the article 12 using the transport device 48 will be described. The transport device 48 is continuously installed up to, for example, a distribution center outlet. Normally, the transport destination is designated by operating the keys of the transport control device 50. The transport device 48 transmits control information to a relay mechanism (not shown) in the transport path so as to control the article 12 to be automatically transported to the designated exit port. In this system, the destination is designated by voice. The transport control device 50 is provided with a reader 18 that reads the sign 16 attached to the article 12. Furthermore, an instruction recognition device 52 for recognizing a voice instructing a transport destination by the worker 11 and a synthetic voice output device 20 for converting the recognition result into a synthetic voice and outputting it. A response recognition device 22 for recognizing the response when the worker 11 responds is also provided. In addition, a registration device 24 that automatically registers the determined information according to the recognition result is provided. The conveyance control device 50 controls the conveyance path of the article 12 according to the registered contents. Thereby, it is possible to input an instruction by voice to the transport destination for an apparatus for transporting the article 12 to various places. Accordingly, it is possible to prevent mistakes more reliably than when operating keys and the like. Specific examples will be described below.

  For example, the article 12 picked up in the first embodiment is conveyed by the conveying device 48. In this example, a belt conveyor is illustrated. However, the same can be done with an automatic transfer device using a self-propelled cart. The conveyance path of the conveyance device 48 shown in the figure is complicatedly branched depending on the destination. In this case, a reader 18 for reading a barcode attached to the article 12 is arranged at various points on the conveyance path. In this example, when the transport destination is designated, the label printer 58 prints a new sign 60. This indicator 60 is a bar code or a QR code. Accordingly, the signs 16 and 60 are affixed to the article 12.

  For example, when the worker 11 indicates the destination with “R2 gate” by voice, the microphone of the headset 23 transmits the voice to the radio device 21 of the transport control device 50. The voice received by the wireless device 21 is recognized by the instruction recognition device 52. At that time, the transport destination recognition data 54 of the storage device 26 is used for collation. Since the transport destination is expressed by a simple symbol, it is preferable to register it all in the transport destination recognition data 54. When the transport destination is recognized, the synthesized voice output device 20 synthesizes a voice to repeat it. This is sent to the headset 23 of the worker 11 through the wireless device 21. The worker 11 responds with a simple answer of “yes” or “no”. This is recognized by the response recognition device 22 and the confirmation process is terminated. The registration device 24 registers the result as the conveyance record data 56. Then, the label printer 58 is driven to print out the sign 60. Information indicating that the designated article is conveyed to the “R2 gate” is displayed on the sign 60. Further, the transport record data 56 is transferred to the management server 38 through the LAN interface 19 and the network 40 and registered. As described above, when the voice recognition function is attached to the transport control device 50, the entry / exit management of the article 12 by voice control can be further diversified.

  In addition to storing, taking out, and transporting the article 12, when the article 12 is discarded, voice can be used for quantity management. A reader 18 may be provided at the entrance of the disposal apparatus. For example, when processing with a shredder, it is troublesome to simultaneously input the disposal record of the article 12 with a key or the like. If the disposal record can be automatically registered by voice operation, the burden on the operator can be reduced. This system can be realized as it is with the apparatus shown in FIG. Assume that the article 12 to be discarded is stored in the storage box 29. The operator 11 takes out the article 12 and reads the mark 16 with the reader 18. The wheelbarrow 30 is a transporting device that carries articles to be discarded. Alternatively, an article disposal apparatus such as a shredder is used. The information read by the reader 18 is made into a confirmation message by the synthesized voice output device 20. For example, a message such as “Discard one item ***” may be output. In this way, it is possible to sort out the objects to be discarded while checking with the ear. In addition, when the discard process is performed, the result can be automatically registered in the server.

  The above system can be used not only for warehouse picking work but also for in-house work such as incoming inspection and calibration. Further, for example, it can be used for managing the location, use, and disposal of depositor contracts, business contracts, borrower contracts, bankbooks, etc. in financial institutions. For example, contracts for depositors, contracts for traders, contracts for borrowers, bankbooks, etc. are conventionally handled as follows. That is, each of which is stored a predetermined form printed on a predetermined sheet. In addition, the actual signature and seal are stored. Each signed and sealed contract must be kept strictly for the relevant period.

  Inadvertent disposal of unused bankbooks and contract forms is prohibited. For example, when the form is changed, the quantity is confirmed and discarded by the shredder. As long as there is no change in the format of the standard form of the contract, the bankbook, etc., the required number of sheets is ordered every predetermined period. These are stored at the headquarters and branch offices of financial institutions, but we want to manage the location and management status at the head office. In this system, for example, the following HW is used.

  First, print barcodes or stick barcode labels on all documents. An IC tag or a two-dimensional barcode may be used as a marker. When creating a contract, scan the barcode on the handy terminal. Here, as in the above-described embodiment, a voice confirmation operation is performed. For example, the barcode data is dedicated to a contract. That is, the type of contract, the serial number of the contract, and the handy terminal code are output as synthesized speech. When the worker answers “yes”, the contents are registered in the server. Similarly, a confirmation process using voice is preferable for the storage destination. This makes it possible to securely register in the server which document is processed and stored in which department.

  The shredder is also equipped with a handy terminal. At the same time as disposal, the same voice confirmation is made and registered in the server. The printed passbook is printed with a barcode from the beginning. All management is combined with barcodes and IC tags and voice confirmation processing, and automatic registration processing to the server is performed. By such management, printing, storage, and disposal of all documents can be reliably managed, and input errors and input mistakes can be prevented.

FIG. 4 is a schematic diagram illustrating an article access management system according to the sixth embodiment.
The article entry / exit management system shown in the figure is used to pick up articles from a warehouse, for example, as in the first embodiment. The pickup control device 34 of this embodiment has a configuration in which a product code database 61 is newly stored in the storage device of the device shown in FIG. The product code database 61 is a data group in which numbers and names used for collation of at least names of product codes are associated with each other.

  Further, the name collation device 62 determines whether or not a combination of a name recognized for speech and a number used for collation of the name exists in the product code database 61. The recognition result indicating that the process for handling the article has been executed is confirmed and transferred to the registration device. In addition, when there is no function, it is determined that the name is recognized incorrectly, and a function for executing a process of requesting the synthesized speech output apparatus 20 to output a speech synthesized speech requesting re-reading such as “Please read the product name again” is provided. Have. The instruction recognizing device 52 has the same configuration as that of the third embodiment, and has a function of recognizing the name of an article that is the object of entry / exit management and a voice that reads out a number used for matching the name. The registration device 24 has a function of automatically registering a confirmed result among the recognition results of the instruction recognition device.

FIG. 5 is a diagram for explaining the operation of the pickup control apparatus according to the sixth embodiment.
For example, a case where an operator picks up an article packaging box 63 containing articles as shown in the figure will be described. A name label 64 and a bar code label 65 are affixed to the article packaging box 63. When picking up this article, the operator may read the bar code label 65 by operating the reader 18. However, when the operator carries the article with both hands, the reader 18 cannot be operated. In this embodiment, the operator can input the name by reading a part of the numerical value display 66 printed on the name printed on the name label 64 and the barcode label 65. In this way, the operation of operating the reader 18 before and after the operation of putting in and out the article can be omitted.

  In this embodiment, a voice recognition process is used at the time of picking an article, thereby simplifying picking data input work and confirmation work. However, when a speech recognition process is executed simply by reading a name, a recognition error may occur. For example, when handling a new product or the like, erroneous data may be input to the database due to misreading or misrecognizing names. If the frequency of recognition errors is high, the system for simplifying picking data input work and confirmation work will not function sufficiently.

  Therefore, in this embodiment, at the time of picking, the name is read out and a part of the numerical value display 66 printed on the barcode label 65 is read out. In this example, the voice recognition apparatus recognizes the product name “PATPC” and the last three digits of the numerical display 66. In the product code database 61, a name 68 and a product code 69 are stored in pairs. In this embodiment, the product code 69 is stored in all digits, but only the last three digits may be stored. In this way, the product code database 61 and the result of voice recognition are collated. In the figure, two types of results of speech recognition are illustrated.

For example, it is assumed that the first recognition result is “PETPC397”. Here, the product name “P A TPC” is erroneously recognized as “PETPC”. At this time, there is no data set in which the product name is “PETPC” and the last three digits of the product code 69 are “397”. Therefore, the name verification device 62 requests the synthesized speech output device 20 to output a message. The message is, for example, “Please read the product name again”. In response to this, the operator reads out the product name and a three-digit number again.

The following has been recognized as "P A TPC397". When matched with the product code database 61, a corresponding set exists. Therefore, the name verification device 62 requests the registration device 24 to register data indicating that the article having the name “P A TPC” has been picked up. The following is the same as the previous examples. Voice recognition processing for numerical values is extremely accurate. If it is registered as a reserved word, it can be recognized accurately with no practical problem. On the other hand, there are many similar names, and errors are likely to occur. In particular, if the name resulting from the recognition error matches the name of an article, an erroneous input occurs. In the system of this embodiment, such a state can be avoided.

  The last 3 digits of the product code 69 may be the last 4 digits or the last 2 digits. For example, it may be controlled to recognize the number of digits of the read-out number and automatically collate with the number of digits. For example, this is effective when an article having the same last three digits is accidentally stored on the same shelf or an adjacent shelf. For example, from the beginning, a function of outputting information for restricting the storage location may be provided so as not to store an article whose lower-order product code 69 matches a neighboring shelf. For example, it is preferable to output a message such as “a product whose lower three-digit product code matches is stored in a shelf designated as a storage location for this product (or a shelf adjacent to the shelf)”.

  Note that the apparatus of this embodiment can further reduce the burden on the operator by automatically reading out the contents of the instruction slip and transmitting the instruction to the worker as in the system of the second embodiment. A highly complete system will be realized. Further, a system that includes all the configurations of the first embodiment may be configured so that it can be used separately from the reader of the first embodiment depending on the situation, and the advantages can be mutually complemented.

  Further, in the above example, the product code database 61 stores the names of all articles and a set of numbers used for matching the names. However, for example, in the case of picking up an article based on a predetermined instruction as in the system of the second embodiment, for example, a number used for matching the name of the article and the name included in the instruction content of the instruction slip You only need to register the pair. Since other items are not handled, it can be verified.

  For example, consider a case where an instruction is issued by synthetic voice based on an instruction slip, and an operator picks up a corresponding article according to the instruction. At this time, even if the operator accurately picks up the corresponding article, if the voice recognition process is ambiguous, it is determined that the article as instructed is not picked up. Therefore, when the number used to match the name of the instructed item and the name of the picked-up item matches, even if the name does not match, the name is determined to match if it is more than a certain approximation To do. In the speech recognition process, the comparison target speech waveform is sampled and the difference value of the digital data is calculated. Usually, the difference value is compared with a certain threshold value to determine whether or not they match. Even if this difference value is greater than or equal to a threshold value, it may be determined that the difference is approximated if it is less than a certain value. This makes it possible to flexibly deal with names that are difficult to distinguish not only by misreading but also by individual differences in pronunciation, complementing the ambiguity of speech recognition, and reducing reliability.

  In the merchandise management database, various information for each article is input and registered. Here, at the time of the pick-up work as described above, the person in charge may see the shortage information in the product management database by looking at the instruction slip. Also, the system may automatically recognize the shortage information and remain in a state waiting for input of the shortage information. Furthermore, there is information that cannot be input when goods are received. In this embodiment, a method for inputting such shortage information will be described.

  When the article pick-up process is started, an article name recognition process for the article to be picked up is executed. The contents are as described in the above embodiment. Here, at a predetermined timing before and after the article pick-up process, the article management database in which information relating to the article is recorded is automatically inspected. Then, the shortage information in the product management database is inspected. When the deficient information is automatically found, the speaker is driven at a predetermined timing before and after the pick-up process to request the voice to input the deficient information.

  In response to this request, the person in charge reads out the corresponding information by voice. If the information corresponding to the packaging box of the article is described, the shortage information can be easily input by this operation. For example, the control device outputs a message “Expiration date information is insufficient” at a predetermined timing. The person in charge pronounces “no information” or “2007201”. In this way, the date input form is determined to be a specific number of digits. In the case of the weight of an article, for example, the integer part on the left side of the decimal point is determined as 3 digits and the decimal part on the right side is determined as 1 digit. Therefore, if it is 80.3 kg, it may be pronounced as “0809”. Thereby, only the numerical value is recognized. Therefore, individual differences can be absorbed by reserved word processing, and voice recognition processing can be performed relatively accurately.

  On the other hand, when the person in charge spontaneously finds missing information by looking at the information printed on the instruction slip, the person in charge pronounces the input of “insufficient information” at a predetermined timing. Thereby, the shortage information input mode is entered. Next, for example, it is pronounced “net expiration”. This enters the net deadline input mode. After that, “20070201” may be pronounced. Thus, the shortage information supplement process can be completed together with the pickup process.

  Furthermore, the process which writes the predetermined information of a merchandise management database to an article | item and the IC tag attached to the article | item can be linked. It is also possible to fully automate this process. Whether or not necessary information is written on the IC tag is an important problem in the subsequent handling of the article. Therefore, it is desirable that the person in charge of the pickup process can confirm the writing to the IC tag on the spot. It is preferable to be able to recognize that the latest information has been written to the IC tag by inputting or updating the missing information.

  Therefore, in this embodiment, label printing and IC tag writing are linked. That is, when the input of the shortage information is completed, the merchandise management database is updated, and a label to be attached to the article is printed out from a portable label printer. At this time, you may print the barcode which displayed article information on the label. For those using an IC tag, information is written to the IC tag at the same time. In order to notify the person in charge of the pickup processing or the like of the completion of writing to the IC tag, for example, the fact that information has been written to the IC tag and the writing time are printed on the label. In addition, a message “The input information has been written to the IC tag” may be output by voice. As a result, the article information of the article to be picked up and shipped can be maintained and shipped with peace of mind.
