Description

  The present invention relates to a shipping instruction apparatus suitable for use in shipping a plurality of types of shipments produced in, for example, an automobile engine manufacturing factory.

  For example, in a production system for producing a plurality of types of automobile engines as shipments, various shipments 50 (in the illustrated example, 50A, 50B, 3 types of 50C) are flowed through the assembly line 51 in a seemingly random order. Then, as shown in the figure, the completed shipment 50 is stored in a storage place (finished product yard) 53 until it is shipped in a state where it is stored in a container (for example, pallet) 52 for each type, and is shipped for each destination at the time of shipment. The container is transferred to a container (for example, shipping pallet) 54.

  In the above conventional shipping method, since the shipment 50 is stored in the storage location 53 by type, the picking operation (selection operation) of the shipment 50 for loading from the storage location 53 to the shipping container 54 at the time of shipment is easy. And can be done quickly.

  However, in the above-described shipping method, there is no guarantee that when the shipment 50 is shipped, it is possible to accurately specify the one with the earliest production time or storage time among the plurality of shipments 50 stored in the storage location 53. There is a concern that products having a later manufacturing time (accommodating time) may be shipped first, and the fact that various shipments 50 cannot be shipped in the order of manufacturing (accommodating) is not the best in terms of quality control.

  Further, when a plurality of types of shipments 50 that have flowed randomly through the assembly line 51 are accommodated in the container 52 by type, for example, a shipment 50A of a different type is mistakenly stored in the container 52 for accommodating the shipment 50B. Human error such as containing Further, even if the container 52 can be accurately stored, for example, the container 52 that stores the shipment 50C is mistakenly stored in the storage place of the container 52 that stores another type of shipment 50B. There is also a risk of human error. If these mistakes occur, the wrong shipment 50 is loaded into the shipping container 54 at the time of shipment, which may cause a serious man-made disaster at the shipping destination and thereafter.

  In addition, for example, when a defect is found in an assembled part, even if the identification number of the shipment 50 in which the defective part is assembled can be specified, it is stored to check the label with the identification number. The shipments 50 at the location 53 must be checked one by one, and there is room for improvement in this respect as well.

  The present invention has been made in view of the above circumstances, and its purpose is to simultaneously improve the quality control of shipments and to reduce human error as much as possible, and to find defective shipments.

  The shipping instruction apparatus according to this embodiment is for issuing a shipping instruction for the shipment 1, and the presupposed configuration will be described first.

  As shown in FIG. 1A, the shipment 1 in this embodiment is produced through an assembly line 2 constituted by a conveying device (for example, a conveyor) while being held on an assembly pallet P. A plurality of types of automobile engines, which are configured by appropriately assembling a crank (crankshaft), a head (cylinder head), a cam (camshaft) and the like to a cylinder block.

  As described above, the shipment 1 that has passed through the assembly line 2 is unloaded from the assembly pallet P, and is stored by type in a plurality of containers (for example, pallets) 3 disposed near the end point of the assembly line 2. The And the container 3 which accommodated the predetermined number (four in this embodiment) shipment 1 is transferred to the storage place (finished product yard) 4, and this storage place is shown in FIG. 1 (A). 4 is stored at a position determined for each type of shipment 1. Further, in the vicinity of the end point of the assembly line 2, an empty container 3 is newly arranged in place of the container 3 carried to the storage place 4 as described above.

  Here, in this embodiment, an example in which the shipment 1 is of three types 1A, 1B, and 1C is shown. Accordingly, the storage place 4 is partitioned and the shipments 1A and 1B accommodated in the container 3 are shown. , 1C storage positions 4A, 4B, 4C, respectively.

  At the time of shipment, one or two or more shipment items 1 are selected from the plurality of types of shipment items 1 stored in the storage location 4, and a shipping container (for example, a pallet) 5 is selected as shown in FIG. Shipped in a housed state.

  The above configuration is not different from the conventional one, and as will be described later, it is possible to give a shipping instruction using the IC tag 6 attached to each of the containers 3 and any shipment 1 The main feature of the shipping instruction apparatus according to this embodiment is that it can be found easily and quickly. Therefore, a characteristic configuration of the shipping instruction apparatus will be described below.

  First, as shown in FIG. 1A, each shipment 1 is provided with an information medium 7 that stores unique identification information. Here, the identification information includes an identification number unique to the shipment 1, information (type number) indicating the type of the shipment 1, and a production time (for example, production date and time) of the shipment 1. The information medium 7 is, for example, a label printed with a bar code or an IC tag. If the information medium 7 is a label, it may be attached to the shipment 1. What is necessary is just to attach to the shipment 1 using a member.

  The identification information stored in the information medium 7 is read by a reading device (reading unit) 8 and sent to the device main body 9. Here, the reading device 8 is a barcode reader, an IC tag reader or the like that can read identification information from the information medium 7. Further, the apparatus main body 9 transmits a notification instruction for performing a notification operation via the IC tag 6 to a predetermined notification unit 12 (described later) based on the identification information obtained by the reading device 8. Thus, the computer has a programmable controller (SLC) incorporated therein, and is configured to be able to communicate with the IC tag 6 via the IC tag master station 10.

  On the other hand, the IC tag 6 is a wireless IC tag, and as shown in FIG. 1B, a wireless communication antenna 11 for performing wireless communication with the apparatus main body 9 via the IC tag master station 10. An IC chip (not shown), a notification unit 12 that performs a notification operation upon reception of a predetermined signal from the apparatus main body 9, and a battery (not shown) that supplies power to the notification unit 12 And an input unit 13 for inputting storage confirmation information of the shipment 1 to the container 3, take-out confirmation information of the shipment 1 from the container 3, and the like.

  Here, an ID number corresponding to each container 3 is stored in the IC chip.

  In addition, as the notification unit 12, for example, a display lamp that performs lighting (flashing) display as a notification operation, a sound source unit (for example, a buzzer or a speaker) that performs voice display as a notification operation, or other display that displays characters or images. In this embodiment, the display lamp 12a and the sound source unit (not shown) constitute the notification unit 12.

  Further, the input unit 13 is connected to an IC chip, and a push button switch is adopted as the input unit 13 in this embodiment.

  Next, the operation of the shipping instruction device will be described.

  First, as shown in FIGS. 1A and 2, the identification information of the shipment 1 is read by the reading device 8 from the information medium 7 of the shipment 1 that has passed through the assembly line 2. (Step S1).

  The apparatus main body 9 that has received the identification information of the shipment 1 as described above automatically selects and searches the ID number of the container 3 that should accommodate the shipment 1 based on the identification information (step S2). . At this time, the ID number is determined from the selection / search result, and the output format (ON / OFF of the display lamp 12a and the sound source unit) from the notification unit 12 is determined.

  Thereafter, the device body 9 transmits a notification command for causing the predetermined notification unit 12 to perform a notification operation to the IC tag 6 of the container 3 having the corresponding ID number via the IC tag master station 10 (step S3). ). Thereby, the notification command is transmitted to the corresponding IC tag 6, and the notification unit 12 of the IC tag 6 that has received the notification command performs a predetermined notification operation according to the output format determined in step S3.

  By the notification operation, the operator can recognize in which container 3 the shipment 1 should be stored (loaded) and perform the storage (steps S4 and S5). At the same time, the operator operates the input unit 13 (presses the push button switch) in order to input the accommodation confirmation information of the shipment 1 to the container 3. As a result, the notification unit 12 is switched from the ON state to the OFF state. Specifically, the notification unit 12 is turned off when the display lamp is lit, and is muted when the sound source unit is in the audio output state.

  Subsequently, with the input of the accommodation confirmation information by the input unit 13, the accommodation confirmation data including information about the container 3 is transmitted to the apparatus main body 9 via the wireless communication antenna 11 of the IC tag 6, and FIG. As shown in (A) to (C), in the apparatus main body 9, the identification information (the identification number and type of the shipment) and the accommodation confirmation data (the ID number corresponding to the container 3, the date and time of the accommodation, etc.) Is stored as the storage device data 14 in a state of being associated with the storage time (step S6). 3A to 3C show an example in which data having an identification number (E / GNo.) Of the shipment 1 of 1017 is stored and registered.

  On the other hand, in order to ship the shipment 1 stored in the storage location 4, first, as shown in FIGS. 4 and 5, a barcode (not shown) provided in the kanban 15 is read, or a host computer is read. The type information of the shipment 1 to be shipped is input to the apparatus main body 9 by the input from 16 or the like (step S7).

  When step S7 is performed, for example, as shown in FIGS. 6 (A) and 6 (B), all container data 14 (FIG. In the example shown, data No. 1 pallet and data No. 10 pallet) are selected (step S8).

  Further, after step S8, as shown in FIG. 6B, container data 14 corresponding to the container 3 in which the earliest shipment 1 is stored in the apparatus main body 9 (data of No. 10 pallet in the illustrated example). Is searched and selected (step S9).

  Subsequently to step S9, the apparatus body 9 selects the ID number of the container 3 that has been searched and selected (step S10). FIGS. 6A and 6B show an example in which data having an identification number (E / GNo.) Of shipment 1 of 995 is selected. At this time, not only the ID number is determined based on the selection / search result, but also the output format from the notification unit 12 (ON / OFF of the display lamp 12a and the sound source unit) is determined.

  Thereafter, the apparatus main body 9 issues a notification command for causing the predetermined notification unit 12 to perform a notification operation on the IC tag 6 provided in the container 3 that accommodates the shipment 1 having the earliest manufacturing time or storage time. Transmission is performed via the master station 10 (step S11). Thereby, the notification command is transmitted to the corresponding IC tag 6, and the notification unit 12 of the IC tag 6 that has received the notification command performs a predetermined notification operation according to the output format determined in step S10.

  By the notification operation, the worker can recognize from which container 3 the shipment 1 should be taken out, and performs the removal and accommodation (loading) in the shipping container 5 (step S12).

  After the storage, the operator operates the input unit 13 (presses the push button switch) to input the take-out confirmation information of the shipment 1 of the storage device 3 (step S13). As a result, the notification unit 12 is switched from the ON state to the OFF state. Specifically, the notification unit 12 is turned off when the display lamp is lit, and is muted when the sound source unit is in the audio output state.

  Subsequently, along with the input of the take-out confirmation information by the input unit 13, the take-out confirmation information is transmitted to the device main body 9 via the wireless communication antenna 11 of the IC tag 6, and the device main body that has received the take-out confirmation information 9 deletes the container data (identification information and storage confirmation data) 14 corresponding to the shipment 1 having the earliest manufacturing time or storage time, and updates the data (step S14).

  On the other hand, for example, when a defect in the assembly part in the assembly line 2 is found, if the identification information of the shipment 1 in which the defective part is assembled can be specified, by performing the following processing based on this identification information, It is possible to easily and quickly find out the shipment 1 having the above problems from the shipments 1 stored in the storage place 4 in large numbers.

  Specifically, as shown in FIGS. 7 and 8, first, the operator 17 supplies identification information (identification number, type information, production date / time, etc. of the shipment 1) to the apparatus main body 9. Input (step S15).

  Based on the input, the apparatus main body 9 searches and selects the shipment 1 corresponding to the identification information (step S16). FIGS. 9A and 9B show an example in which the identification number (E / GNo.) Of the shipment 1 corresponding to the identification information is 1005.

  Subsequently to step S16, the apparatus main body 9 selects the ID number of the container 3 that stores the searched / selected shipment 1 (step S17). In the example shown in FIGS. 9A and 9B, the ID number of the container 3 is 10. At this time, not only the ID number is determined based on the selection / search result, but also the output format from the notification unit 12 (ON / OFF of the display lamp 12a and the sound source unit) is determined.

  Thereafter, the device body 9 transmits a notification command for causing the predetermined notification unit 12 to perform a notification operation to the IC tag 6 of the container 3 having the corresponding ID number via the IC tag master station 10 (step S18). ). Thereby, the notification command is transmitted to the corresponding IC tag 6, and the notification unit 12 of the IC tag 6 that has received the notification command performs a predetermined notification operation according to the output format determined in step S17.

  By the notification operation, the operator can recognize in which container 3 the defective shipment 1 is stored, and the defective shipment from a small number of shipments 1 in the container 3. The object 1 can be found easily and quickly (step S19). At the same time, the operator operates the input unit 13 (presses a push button switch). As a result, the notification unit 12 is switched from the ON state to the OFF state. Specifically, the notification unit 12 is turned off when the display lamp is lit, and is muted when the sound source unit is in the audio output state. The operation of the input unit 13 in this case is for switching the notification unit 12 to the OFF state, and is not for transmitting a predetermined signal from the IC tag 6 to the apparatus main body 9.

  After the above step S19, the found shipment 1 is taken out from the container 3 and subjected to appropriate checks and corrections (step S20).

  The shipping instruction apparatus 2 configured as described above has the following advantages. First, by sending an instruction using the IC tag 6, when shipping the shipment 1, among the plurality of shipments 1 stored in the storage place 4, the one with the earliest production time or storage time is accurately specified. Accordingly, various shipments 1 can be shipped in the order of manufacture (accommodation), and improvement in terms of quality control and the like can be achieved.

  In addition, when a plurality of types of shipments 1 that have randomly flowed through the assembly line 2 are stored in the storage unit 3 by type according to an instruction using the IC tag 6, for example, a storage unit for storing the shipment 1A It is also possible to reliably prevent human error such as the fact that the different types of shipments 1B are accommodated in FIG. In addition, it is possible to reliably prevent an erroneous shipment 1 from being loaded into the shipping container 5 at the time of shipment.

  In addition, for example, when a defect in an assembled part is found, if the identification number of the shipment 1 in which the defective part is assembled can be specified, an instruction using the IC tag 6 based on the information can be given. Thereby, the shipment 1 which has the malfunction can be searched out easily and quickly.

  The shipping instruction apparatus of the present invention is not limited to the above-described embodiment, and can be implemented with various modifications. For example, in the above-described embodiment, the shipment 1 is an automobile engine. However, the shipment 1 is not limited to such a product, and the shipment instruction apparatus can be widely used for shipment. Can be applied.

  Also, a plurality of music to be output from the sounding unit and how to turn on the display lamp 12a of the notification unit 12 are prepared, and any one of them is arbitrarily selected and executed according to the type or number of parts to be extracted. You may be comprised so that.

  Further, the IC tag 6 has a detection unit (not shown) such as a limit switch or a photoelectric sensor for detecting the storage of the shipment 1 in the container 3 and the removal of the shipment 1 from the container 3. The IC chip may be configured so that the accommodation confirmation information and the removal confirmation information are transmitted from the IC tag 6 to the apparatus main body 9 in accordance with detection by the detection unit. In this case, the detection unit can be driven using the battery of the IC tag 6. In this case, the notification unit 12 may be configured to switch from the ON state to the OFF state in accordance with the detection by the detection unit.

  Here, the notification unit 12, the input unit 13, or the detection unit may be provided integrally with the IC tag 6, but may be a separate body from the IC tag. It may be fixed at 3 etc. Specifically, the IC tag 6 may be configured by appropriately combining (connecting) an RFID tag, a display lamp (notification unit 12), a confirmation switch (input unit 13), and the like.

  Further, the notification unit 12 may be configured to notify the number of parts to be taken out from the container 3 by adding the number of data to the notification command sent from the apparatus main body 9 to the IC tag 6. . In this case, a plurality of instructions for taking out the same part can be instructed, and the efficiency of picking work (selecting work) when collecting (pickup) the shipment 1 for shipment can be improved.

  Further, in the above embodiment, the accommodation confirmation data is sent to the apparatus main body 9 by the operation of the input unit 13 performed simultaneously with step S5, and a predetermined registration process is performed in the apparatus main body 9. For example, the registration process may be performed simultaneously with the transmission of the notification command in step S3.

  Similarly, in the above-described embodiment, an example is shown in which the retrieval confirmation information is sent to the apparatus main body 9 and predetermined data is updated in the apparatus main body 9 by the operation of the input unit 13 in step S13. For example, the data update may be performed simultaneously with the transmission of the notification command in step S11.
