  In a conventional automatic warehouse control system, there are normal full-time work in the flow charts A to F and other special work (see Patent Document 1). When carrying out regular maintenance in the warehouse, the special work may require a place for maintenance work, especially a shelf, and it is necessary to temporarily carry out cassettes, etc. from the shelf to maintain and clean the empty shelf. It is a business to do. In addition to this, when the position accuracy with respect to the shelf of the work transport crane is lowered, it is an operation to readjust the position accuracy, and it is necessary to temporarily prohibit the storage of the corresponding shelf of the specific shelf number.

  FIG. 5 is a flowchart of an example of a conventional work for prohibiting warehousing, which is a special work.

  A description will be given of a work flow for registration of the storage prohibition of the specific shelf number. In the flow diagram a, the worker confirms the receipt state of the shelf with the specific shelf number. The worker confirms the presence / absence of the cassette and the presence / absence of the allocation.

  Then, in flow diagram b, the worker creates an allocation list on the control system. Make sure that a specific shelf number is not allocated.

  Next, in the flowchart c, the worker issues the cassettes from the shelf with the specific shelf number in the order of the allocation list.

  Next, in the flow diagram d, the worker confirms that the cassette has been delivered from the shelf of the specific shelf number, that is, is an empty shelf.

  Next, in the flow diagram e, the worker sets registration of prohibited shelves for each shelf of the specific shelf number.

  As described above, according to the flow charts a to e, the setting of the storage prohibition shelves for the special work by the worker is performed, and the special work is executed.

  Conventionally, in the setting of prohibiting warehousing for each shelf of the specific shelf number, in the state where there is no cassette in the shelf of the specified specific shelf number, or when there is a cassette, It is necessary to register for warehousing prohibition. That is, conventionally, it is necessary for an operator to visually recognize a state where there is no cassette in the shelf of a specific shelf number, and to enter and prohibit entry into the control system. For this reason, the amount of work for workers increases and there are problems such as labor saving. In addition, if there is a cassette on a shelf with a specific shelf number, and the entry is prohibited, the cassette cannot be automatically unloaded and manually unloaded, causing extra trouble such as unfamiliar operation of the manual work crane. There is.

  Conventionally, when a shelf with a specific shelf number has already been allocated and created in the allocation list, there is a problem that the setting of prohibiting warehousing of the shelf with the specific shelf number cannot be registered.

  In the conventional control system, the teaching error of the crane for workpiece transfer, for example, the load sensor cannot be detected on the crane fork for workpiece transfer, the alarm of the misalignment sensor is issued, the operation is stopped, or the maintenance In order to secure the space, when the entry is prohibited, the worker visually confirms in the warehouse, and after the cassette is delivered, the entry prohibition is input on the screen. The input is not allowed until the control system recognizes that the cassette has been issued from the shelf, so that the entry prohibition information for the shelf with the specific shelf number cannot be input, so there is a long time lag, and the worker's workload increases and There is a problem that mistakes are likely to occur.

The known literature is described below.

  The following description is based on an embodiment of an automatic warehouse equipped with the prohibited shelf reservation software of the present invention.

  FIG. 1 is a flowchart of the prohibited shelf reservation software provided in the automatic warehouse of the present invention.

  The prohibited shelf reservation software provided in the automatic warehouse of the present invention is added to an existing control system for storing / extracting stored luggage. The control system is a function for controlling a series of operations related to a multistage rack-like shelf having a uniquely corresponding number, a work transport crane for transporting stored luggage, and a shelf and a work transport crane in an automatic warehouse. It is a system with In the function of the control system, the first is a system classification for registering warehousing / departure information, creating an allocation list based on the information, and warehousing / departing the stored luggage in the order of the allocation list from the control system. The third is a system classification for executing information waiting without the registration of the information of entry / exit. In the present invention, a method is adopted in which the prohibited shelf reservation software can be interrupted and added to the control system only at the time of the system division for executing the information waiting.

  The flow of the prohibited shelf reservation software shown in FIG. First, in the means of the flow diagram a, an arbitrary shelf is selected and reservation information for prohibiting warehousing is set in the control system. The setting of the reservation information is a method for inputting a shelf number for which entry is prohibited.

  There are two means for the reservation information of the prohibited shelf reservation software, and there is a means for reserving entry prohibition in an arbitrary shelf first. Next, it is a means for prohibiting new entry into the reserved arbitrary shelf. In the reservation information registration, a shelf with stored luggage out of arbitrary shelves outputs a carry-out command for carrying out the stored luggage, and an empty shelf outputs a prohibition command for prohibiting entry of a new stored luggage into the shelf.

  In the reservation information, the arbitrary shelf included in the reservation information is deleted from the empty shelf list used when the allocation list is created, and is excluded from the target of the allocation list. By the above method, new warehousing can be prevented at any reserved shelf.

  When there is a case where an allocation list has been created, the reservation information outputs an allocation discard command for discarding the allocation list and a new creation command for creating the allocation list again. By this method, it is possible to eliminate duplicate descriptions of arbitrary shelves reserved in the existing allocation list.

  Next, the means in the flow chart b refers to the empty shelf list for each of the arbitrary shelves and confirms whether or not the stored luggage is present. By the above method, only shelves with stored luggage in any reserved shelves can be extracted.

  Next, in the means of the flow chart c, an allocation list is created for each arbitrary shelf with the stored luggage. With the above method, the preparation for taking out the stored luggage in any reserved shelf has been completed.

  Next, in the means of the flow diagram d, the stored luggage is delivered in the order of the allocation list. By the above method, all the stored luggage was taken out from the reserved arbitrary shelves and became empty shelves.

  Next, in the means shown in the flow chart e, the entry prohibition information is registered for each of the shelves that have been left out and no stored luggage. By the above method, it is possible to register the warehousing prohibition information with confidence using a conventional control system.

  By executing the flowcharts a to e above, entry can be prohibited for each arbitrary shelf, and the arbitrary shelf becomes an empty shelf. By the method using the prohibited shelf reservation software of the present invention, it is possible to carry out a task by system control.

  FIG. 1B is a flowchart illustrating an example of prohibited shelf reservation software added to the existing control system of the present invention.

  In the flow charts A to J shown in FIG. 1B, the flow charts A to B1, which are conventional control systems, and the flow charts B to B and H, which are prohibited shelf reservation software of the present invention, are added to C to E and J. The flowchart I was added as an interrupt.

  The control system of the present invention shown in FIG. In the flow diagram B1, the control system of the present invention registers warehousing / exit information.

  Next, in the flowchart B2, the information on the prohibited shelf reservation software is registered in the information area in the system using the prohibited shelf reservation software of the present invention.

  In the information area, a file of information on entry / exit and a file of information on prohibited shelf reservation software are recorded and prepared according to the rules.

  Next, in the flow chart C, information on the next warehousing / exiting is received from the information area, and preparation for warehousing / exiting is made.

  Next, in the flow chart D, the system 20 for executing warehousing / departing is sequentially executed, for example, creation of an allocation list, warehousing / departing of stored parcels in order by the allocation list, and repeated execution until the end of the allocation list. End the business.

  Next, in the flow diagram E, the system 30 executes information waiting without warehousing / exit information.

  Next, in the flowchart F, the presence / absence of information is confirmed in the information area. If there is information, return to the flow diagram G. If there is no information, return to the flow diagram E. If necessary, go to the flow diagram J and stop the control system.

  Next, in the flowchart G, the presence / absence of prohibited shelf reservation information is confirmed in the information area. If there is information, return to the flow diagram H. If there is no information, return to the flow diagram C and repeat the flow diagrams C to E repeatedly.

Flow diagrams F and G show how to retrieve information at that time. If there is information on prohibited shelf reservation software and information on entry / exit in the information area, priority is given to information on prohibited shelf reservation software. Output. That is, after the information on the prohibited shelf reservation software in the information area is output in order, the information on the warehousing / unloading is returned and output in that order. Note that there is a method of giving priority to information as the output order of information recorded in the information area.

  Next, in flow chart H, information on prohibited shelf reservation is received from the information area, and preparation for prohibited shelf reservation is made.

  Next, in the flowchart I, the system 10 for executing the prohibited shelf reservation software is executed. For example, setting reservation information for banning entry, creating an allocation list for evacuation from the shelf, executing storage baggage in order using the allocation list, and registering warehousing prohibition information, and ending the work To do.

  Then, returning to the flowchart F, the flowcharts E to G are repeatedly executed again, and the flowcharts C to I are repeatedly executed sequentially while waiting for additional information. In the flow charts C to I, the system 20 that executes warehousing / unloading, the system 10 that executes prohibited shelf reservation software, or the system 30 that executes information waiting is being executed.

  The interruption of the prohibited shelf reservation software to the control system of the present invention is an interruption of the control system prior to the registration of the warehousing / departure information, and the timing of interruption to the control system is a system division for executing the information waiting. In the system of FIG. 1 (b), the output of information is allowed only for the flowchart E, and the registration of information is optional.

  In one embodiment of the control system of the present invention, the system is installed in an automated warehouse. The automated warehouse is attached to the production line. In the automated warehouse, product boards, intermediate products, products, and process materials are stored on shelves, and the stored luggage is received / exited as necessary. There is normal business to do. The shelves arranged in a rack in a three-dimensional form are assigned a unique number (shelf number), and are associated with a storage number of a stored luggage having a unique number, for example, a lot number. There is a job to output a shelf storage status list with / without. The workpiece transfer crane automatically carries in / out of goods according to instructions from the control system and an allocation list. As necessary for maintenance, etc., prohibition shelf reservation software for setting prohibition of storage is arbitrarily interrupted and added to an arbitrary shelf in a state where the stored luggage has been received, and is automatically prohibited from entering the shelf. In the control system of the present invention, the information on entry / exit or the information on prohibited shelf reservation software is registered in the information area, and the registered information is output to the system one by one. In the present invention, the output order of the registered information is that the information on the prohibited shelf reservation software is at the top, that is, the higher order, and the information of warehousing / exiting is the lower order. For this reason, for example, when registration of the information on the prohibited shelf reservation software is completed, after the system 20 that executes the loading / unloading being completed, the information retrieval after the system 30 that executes the information waiting is used to retrieve the information on the prohibited shelf reservation software. The system 10 for executing the acquisition and prohibited shelf reservation software is executed. Thereafter, when the system for executing the prohibited shelf reservation software is finished, the system for executing the warehousing / unloading is executed again.
