Description

  The present invention relates to a shipping system and a shipping method that are suitable for use in shipping a shipment-scheduled product such as an automobile engine that is produced in line at a manufacturing plant, for example.

  For example, in a production system that produces engines for a plurality of types of automobiles, as shown in FIG. 5 (A), the assembly lines are usually assembled in a seemingly random order, as shown in FIG. 2 to install parts. Here, FIG. 5A is an explanatory view schematically showing the configuration of a conventional engine production system.

  After that, the engine as the planned shipment 1 for which assembly has been completed is started after the fuel / cooling water is supplied in the test bench (test device) 52, and is checked (inspected) and adjusted one by one in this state. . The engine completed through such a process is stocked (stored) in the stock section (shipping place) 5 until it is shipped in a state of being housed in a container (for example, pallet) 53 by type, and a container for shipping according to a destination at the time of shipment. (For example, shipping pallet).

  However, in recent years, the precision of various parts to be mounted on the engine has improved dramatically, so that it is not necessary to start the fuel and cooling water into the engine one by one and start the engine with an external motor. By turning and checking the load state (compression ratio, resistance, rotation, etc.), it is now possible to judge the quality of the engine.

  However, since it is necessary to actually start the engine for the sensory test (sound, vibration, oil / water leakage check test), as shown in FIG. ) Sensory test (firing test) at the rate of one unit. FIG. 5B is an explanatory diagram schematically showing the configuration of an improved example of a conventional engine production system. In this figure, 6 is an inspection unit for a firing test.

  In the production system, since a test (firing test) that requires engine start is performed not for all engines but only for a part, it is possible to suppress the generation of warming gas, etc. associated with engine start. And can be optimized in terms of the natural environment.

  By the way, in the production system shown in FIG. 5B, since the sensory test of the engine is performed by the sampling inspection as described above, all the engines are divided into a plurality of lots. And if some of the engines that make up the lot pass the firing test, the quality of the entire lot is guaranteed, so the lot test results from the firing test (sampling inspection) performed on some of the engines in the lot. The overall pass / fail is determined.

  However, in the production system, the engine 1 constituting a lot whose pass / fail based on the result of the firing test is not known may be stocked in the stock unit 5, and such an unguaranteed engine is a human error or the like. May be shipped. And when such shipment is performed, it may cause a serious man-made disaster etc. in a shipping destination or after that.

  The present invention has been made in view of the above circumstances, and its purpose is to ship only shipments that are guaranteed based on a sampling inspection for quality assurance, and to ensure shipment of unguaranteed shipments. It is an object to provide a shipping system and a shipping method that can be prevented.

  In order to achieve the above object, a shipping system according to the present invention includes a line for transporting shipments that constitute a plurality of lots, a stock unit for stocking shipments that have passed through the lines, and sampling the shipments. A shipping system including an inspection unit for inspecting, wherein a first input means for inputting identification information of a planned shipment that has passed a sampling inspection, and a sampling inspection is received from the identification information input by the first input means. Information management means for associating the result of the sampling inspection with the identification information of the shipping schedule that constitutes the same lot as the shipping schedule, and second input means for inputting the identification information of the shipping schedule in the stock section, Shipment determining means for determining that shipment is possible if the result of the sampling inspection is associated with the identification information input by the second input means, and for determining that shipment is not possible if not associated It is characterized by comprising (claim 1).

  In addition, the shipping system according to the present invention includes a line for transporting planned shipments constituting a plurality of lots, a stock unit for stocking the planned shipping products that have passed through the lines, and an inspection unit for sampling and testing the planned shipping products. A shipping system provided with a first input means for inputting identification information of a planned shipment that has undergone a sampling inspection and a result of the sampling inspection, and received a sampling inspection from the identification information input by the first input means. An information management means for associating the result of the sampling inspection with the identification information of the shipping schedule constituting the same lot as the shipping schedule, a second input means for inputting the identification information of the shipping schedule in the stock section, and If the result of the sampling inspection is associated with the identification information input by the second input means, whether or not shipment is possible is determined based on the result of the sampling inspection. May be characterized in that a determining shipment judging means and disable the load (claim 2).

  On the other hand, in order to achieve the above object, a shipping method according to the present invention is a shipping method for shipping a shipment to be shipped which is stocked in a stock section and is sampled and inspected by an inspection section after being conveyed on a line. The step of inputting the identification information of the planned shipment that passed the sampling inspection by the first input means, and the same as the planned shipment that has undergone the sampling inspection based on the identification information input by the first input means The step of associating the identification information of the planned shipment constituting the lot with the result of the sampling inspection by the information management means, the step of inputting the identification information of the planned shipment in the stock section by the second input means, If the result of the sampling inspection is associated with the identification information input by the second input means by the determination means, it is determined that the shipment is possible. It is characterized by having a determining impossible (claim 3).

  In addition, the shipping method according to the present invention is a shipping method for shipping a planned shipment which is stocked in a stock section after being line-conveyed and is also subjected to a sampling inspection by the inspection section. And the identification information of the shipment scheduled items constituting the same lot as the shipment scheduled items subjected to the sampling inspection based on the identification information input by the first input means and the identification information input by the first input means.

  That is, in the inventions according to claims 1 and 3, whether or not the planned shipment in the stock section is guaranteed based on the sampling inspection by the first and second input means, the information management means and the shipping judgment means. Therefore, it is possible to reliably prevent an erroneous shipment of an unguaranteed shipment plan.

  In addition, in the inventions according to claims 2 and 4, since the acceptance of the result of the sampling inspection is input by the first input means, the same lot as that of the planned shipment which failed the sampling inspection is constituted. The planned shipment can be positively excluded from the stock section, and the effect can be further enhanced in terms of preventing erroneous shipment of the unguaranteed planned shipment.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory diagram schematically showing a shipping system and a shipping method according to an embodiment of the present invention, and FIG. 2A is a schematic diagram showing the configuration of a shipment planned item to be shipped by the shipping system and the shipping method. 2B is an explanatory diagram schematically showing the operation of the shipping system and the shipping method for shipping the planned shipment shown in FIG. 2A, and FIGS. ) Is an explanatory diagram schematically showing the operation of the main part of the shipping system, and FIG. 4 is an explanatory diagram schematically showing the configuration of data managed by the shipping information board of the shipping system.

  The shipping system and the shipping method according to this embodiment are for preventing an erroneous shipment of an unguaranteed shipping-scheduled item 1, and FIG. 1 shows the precondition for using this shipping system and the shipping method. The description will be given with reference.

  The shipping system shown in FIG. 1 is for shipping a plurality of types of automobile engines that are line-produced as a shipment object 1. Then, as shown in FIG. 1, the planned shipment 1 is produced through an assembly line 2 constituted by a conveying device (for example, a conveyor) or the like while being held on the assembly pallet P, and is supplied to the cylinder block. A crank (crankshaft), a head (cylinder head), a cam (camshaft), and the like are appropriately assembled.

  The planned shipment 1 that has passed through the assembly line 2 as described above is rotated by a motor from the outside in a test bench (test apparatus) 3 to be driven, and the load state (compression ratio, resistance, rotation, etc.) at this time ) Is checked. Thereafter, the shipment object 1 is transferred to the stock unit 5 by a transport line 4 constituted by a transport device (for example, a conveyor), and stocked (stored) in the stock unit 5 in a state of being arranged by type.

  Some of the products to be shipped 1 pass through the test bench 3 and are then sent to an inspection unit 6 for sampling inspection (firing test). In this state, a sensory test (a sound, vibration and oil / water leakage check test) is performed, and then transferred to the stock unit 5 through the transfer line 4. Needless to say, the planned shipment 1 inspected by the inspection unit 6 may be directly transferred to the stock unit 5 without being sent to the transport line 4.

  At the time of shipment, one or two or more shipment schedules 1 are selected from the plural types of shipment schedules 1 stocked in the stock section 5 and are stored in a shipping container (for example, a pallet). Shipped.

  The configuration of the above shipping system is not different from the conventional one. In the following, a characteristic configuration of the shipping system will be described.

  First, the shipping system receives a sampling inspection from the first input means 7 for inputting the identification information of the planned shipment 1 that has passed the sampling inspection in the inspection section 6 and the identification information input by the first input means 7. The information panel 8 as information management means for associating the result of the sampling inspection with the identification information of the shipping schedule 1 constituting the same lot as the shipping schedule 1 and the identification information of the shipping schedule 1 in the stock section 5 The second input means 9 for inputting the information and the identification information input by the second input means 9 determines that the shipment is possible if the result of the sampling inspection is associated, and otherwise determines that the shipment is impossible. And a shipping instruction device (for example, a computer incorporating a programmable controller (SLC)) 10 as shipping determination means. The information panel 8 and the shipping instruction device 10 may be integrated.

  In addition, each shipping object 1 is provided with an information medium (not shown) storing unique identification information. Here, the identification information includes an identification number unique to the planned shipment 1, information indicating the type of the planned shipment 1 (type symbol), and the production time (for example, production date and time) of the planned shipment 1. ing. The information medium is, for example, a label printed with a barcode, an IC tag, or the like. If the information medium is a label, the information medium may be attached to the planned shipment 1 or the pallet P holding the IC tag. In such a case, it may be attached to the shipping scheduled item 1 or the pallet P holding the same using an appropriate binding member.

  The identification information stored in the information medium is read and input manually (or automatically) by the first input means 7 and the second input means 9, and a communication unit (for example, an apparatus incorporating communication software). 11 and 12 to the information board 8 by wireless or wired communication. Here, the first and second input means 7 and 9 are a barcode reader, an IC tag reader or the like that can read identification information from an information medium, and are detachable from the communication units 11 and 12. . In the present embodiment, each of the first and second input means 7 and 9 is a handy terminal. The first input means 7 and the communication unit 11 may be integrated, and similarly, the second input means 9 and the communication unit 12 may be integrated.

  Next, the operation of the shipping system will be described with reference to FIGS. In the following, the operation in the case of shipping a total of 15 shipments A, B, and C by a shipping system with 15 units in total will be described. is there. That is, in FIG. 2 (A), the scheduled shipment 1 (A-1) on the right end side flows through the transport line 4 starting from the top, and from the beginning to the fifth scheduled shipment 1 (B-2). The first lot, from the sixth planned shipment 1 (A-3) to the tenth planned shipment 1 (A-5) is the second lot, the eleventh planned shipment 1 (B-4) To 15th shipment scheduled item 1 (A-7) is the third lot. In addition, as shown in FIG. 1-No. An identification number up to 15 and a type symbol indicating any one of A, B, and C are given, and this identification information is stored in the information medium as described above.

  First, as shown in FIG. 1 and FIG. 2 (A), each shipment object 1 is checked by the test bench 3 via the assembly line 2, and the test result is tested together with the identification information of the shipment object 1. The data is sent and recorded from the bench 3 to the information board 8 by wired or wireless communication. That is, the test bench 3 is provided with a reading device (not shown) for reading the identification information from the information medium of the planned shipment object 1, and the reading device includes the first and second input means. 7 and 9 can be used.

  Here, as shown in FIG. 4, the information board 8 includes an identification number column 8a described as “E / G No.”, a type symbol column 8b described as “E / G type”, and “test A database having a test result column 8c described as “bench result”, a sampling inspection result column 8d described as “firing result”, and a shipment propriety column 8e described as “shipment” is provided. 1 is configured to record (write) data corresponding to the identification number, type symbol, test result, sampling inspection result, and availability of shipment.

  Of the identification information and test results sent from the test bench 3 to the information board 8, the identification information is written in the identification number column 8a and the type symbol column 8b, and the test result is written in the test result column 8c. . FIG. 4 shows an example in which “OK” is written in the test result column 8c as the test result (pass).

  On the other hand, as shown in FIG. 3 (A), the planned shipment 1 that has reached the transfer line 4 via the test bench 3 is sequentially directed to the stock section 5, but the final planned shipment 1 ( B-2) is taken out from the transport line 4 for sampling inspection and transferred to the inspection section 6 (see FIG. 3B). Then, a sensory test (firing test) is performed on the product 1 to be shipped in the inspection unit 6, and if the test is passed, the product to be shipped is sent by the first input means 7 as shown in FIG. The identification information read from one information medium and the sampling inspection result are sent to the information board 8. And in the information board 8, after collating the said identification information, a sampling inspection result is written suitably. FIG. 4 shows an example in which “OK” is written in the sampling inspection result column 8d as the sampling inspection result (pass).

  On the other hand, since the first to fourth shipments 1 in the first lot are not subjected to the sampling inspection, only “-” is written in the sampling inspection result column 8d. When the 5th scheduled delivery item 1 of the first product passes the sampling inspection, “OK” is written in the shipping availability column 8e, indicating that the quality of all 5 units in the first lot can be guaranteed. It is. That is, in the information panel 8, the other four shipping scheduled items 1 constituting the same lot (first lot) as the shipping scheduled item 1 subjected to the sampling inspection from the identification information input by the first input means 7. The result of the sampling inspection is associated with the identification information.

  Thereafter, as shown in FIG. 3C, the planned shipment 1 that has passed the test in the inspection unit 6 is returned to the transport line 4 and headed toward the stock unit 5. Here, since the test in the inspection unit 6 takes time for three shipments 1 passing through the conveyance line 4 to pass in front of the inspection unit 6, the shipments 1 (B-2) returned to the conveyance line 4 are required. ) Flows following the three shipments 1 in front of the second lot.

  Then, as shown in FIGS. 3D and 3E, only the fifth planned shipment 1 (A-5) is subjected to a sampling inspection for the second lot as well as the first lot. . That is, the same processing as the first lot is performed for the second lot and the third lot.

  In FIG. 3 (E), the final shipment scheduled item 1 (A-5) of the second lot is being inspected by the inspection unit 6, and the first shipment planned item 1 of the third lot is The stock stock 5 is shown in a stocked state. As is clear from this figure, the stock 5 is arranged with the products 1 to be shipped in a vertical row for each of A, B, and C types.

  In FIG. 2B, the fourth shipment scheduled item 1 (B-5) of the third lot is being tested on the test bench 3, and the final shipment scheduled item 1 ( A-5) is being inspected by the inspection unit 6, and the third shipment object 1 (A-6) of the third lot passes in front of the inspection unit 6, and the second unit of the third lot. FIG. 4 shows the state of the information board 8 corresponding to the state at this point in time, when up to 11 items to be shipped (total 11 items to be shipped 1) are stocked in the stock unit 5. It is shown.

  At this point in time, as shown in the test result column 8c of FIG. 4, all of the planned shipments 1 of the first lot and the second lot 10 have all passed the test on the test bench 3, and FIG. As shown in 4 of the sampling inspection result column 8d, the final shipment scheduled item 1 (B-2) of the first lot has also passed the sampling inspection. Therefore, as indicated by “OK” in the shipping availability column 8e of FIG. 4, it is determined that all of the five shipping scheduled items 1 in the first lot can be shipped. On the other hand, as shown in the sampling inspection result column 8d in FIG. 4, the final shipment scheduled product 1 (A-5) of the second lot has not yet been subjected to the sampling inspection result (sent to the information board 8). Therefore, as indicated by “NG” in the shipping availability column 8e of FIG. 4, it is determined that all of the five scheduled shipments 1 in the second lot cannot be shipped.

  Accordingly, as shown in FIG. 2 (B), the four shipment-scheduled items 1 (A-1, A-2, B-1, C-1) in the first lot in the stock unit 5 are stored in the shipping container. 13, when the identification information read from the information media of the four shipment items 1 is transmitted to the information board 8 by the second input means 9 and the communication unit 12, any shipment schedule The shipment instructing device 10 determines that shipment of the object 1 is possible, and a message to that effect is displayed on a display unit (for example, a display device) (not shown) of the second input means 9. Further, if the second lot shipping schedule 1 in the stock section 5 is to be shipped, identification information is transmitted from the information medium of the shipping schedule 1 to the information board 8 by the second input means 9 and the communication unit 12. In this case, the shipping instruction device 10 determines that the shipping is impossible, and a message to that effect is displayed on the display unit of the second input means. Then, the shipping operator can surely prevent the erroneous shipment of the unguaranteed shipping scheduled item 1 by following the display on the display unit.

  When the display unit of the second input means 9 indicates that the shipment is possible, and the shipment planned item 1 is shipped according to this display, the second input means 9 is set in the communication unit 12 and the shipment planned shipment item is shipped. 1 identification information (shipping result (history)) is transmitted to the information board 8, and the corresponding information is deleted from the information board 8.

  Note that the shipping system and shipping method of the present invention are not limited to the above-described embodiments, and can be implemented with various modifications. For example, in the above-described embodiment, an example in which the shipment object 1 is an automobile engine has been described. However, the shipment object 1 is not limited to such a product, and the shipment is widely applicable to items that can be shipped. Systems and shipping methods can be applied.

  Moreover, in the said embodiment, although the number of each lot is five units, it is not restricted to five units. Further, the sampling inspection of the inspection unit 6 is performed only on the last shipment planned item 1 of each lot, but any shipment planned item 1 of each lot may be sampled and the number thereof is one. Not limited.

  In the above embodiment, the second input means 9 and the communication unit 12 transmit the identification information read from the information medium of the planned shipment 1 in the stock unit 5 to the information board 8, and the shipping instruction device 10 Although it has been determined whether or not the shipment is possible, the present invention is not limited to this. For example, the identification information of the shipment object 1 determined to be shipped by the shipment instruction apparatus 10 is second input from the information panel 8 via the communication unit 11. The identification information is read by collating the identification information read from the planned shipment 1 with the identification information of the planned shipment 1 determined to be shipped in the second input means 9. The availability of shipment of the shipment object 1 may be displayed on the display unit.

  In the above embodiment, the determination result of the shipping instruction device 10 is displayed on the display unit of the second input unit 9. However, the present invention is not limited to this, and a display unit is provided in addition to the second input unit 9. Then, the determination result of the shipping instruction device 10 may be displayed on the display unit. For example, a display unit can be provided in the shipping instruction apparatus 10.

  Moreover, in the said embodiment, although only the identification information of the to-be-shipped goods 1 which passed the sampling inspection in the test | inspection part 6 is read and input with the 1st input means 7, it is not restricted to this but sampling inspection is carried out. The identification information of the shipment object 1 that has been rejected is also read and input, and the result of the sampling inspection in addition to the identification information of the shipment object 1 is also transmitted to the information panel 8 via the communication unit 11. Also good. In this case, the information panel 8 determines the identification information of the planned shipment 1 that constitutes the same lot as the planned shipment 1 subjected to the sampling inspection from the identification information input by the first input means. The result of the sampling inspection may be associated with the information, and if the result of the sampling inspection is associated with the identification information input by the second input means by the shipping instruction device 10, the sampling inspection is performed. Based on the result, it is determined whether the shipment is possible (when the sampling inspection is acceptable, the shipment is possible, and when it is unacceptable, the shipment is impossible). When configured in this way, it is possible to positively check the planned shipment 1 that constitutes the same lot as the planned shipment 1 that failed the sampling inspection.
