Description

[Technical field]

[0001] The present invention relates to the generation, storage and management of production history information in packaging machines such as pillow packaging machines, wrapping packaging machines and overwrap packaging machines. [Background technology]

[0002] 2. Description of the Related Art Food products and other such products are packaged using packaging machines such as pillow packaging machines, wrapping packaging machines, and overwrap packaging machines, packed into boxes, shipped, and distributed to the market for consumption. In this case, if a package containing a product (packaged item) turns out to be defective and is distributed on the market, the defective items will need to be recalled. However, if there is a history that records the manufacturing conditions, etc., of the manufacturing process for each package distributed on the market, then by tracking that history, the defective items can be recalled quickly and efficiently, which will lead to a reduction in the number of subsequent defective items and improved quality. For this reason, the importance of so-called traceability, which involves recording the manufacturing conditions at each stage from packaging of the product (packaged item) to shipping and making the history of each package traceable, has increased, and various devices and systems have been proposed to achieve this.

[0003] For example, Patent Document 1 (JP 2009-196694 A) discloses a quality recording device for packaged products in a packaging machine that includes: data input means for inputting setting values ​​for controlling specified control objects regarding item data capable of identifying the packaging type, such as the size, type name, and product number of the packaged product, and the packaging conditions for each packaging process of the packaged product; storage means for obtaining actual measurement values ​​for the control objects at the time each packaged product reaches each packaging process by detection means and storing the actual measurement values ​​as packaging quality data for each packaged product associated with the setting values ​​as current values ​​at the time the packaged product is packaged; control means for outputting a print signal for printing the packaging quality data stored in the storage means as a quality record for each packaged product; and a printer for receiving the print signal and printing out a quality record document. In the packaged product quality recording device of Patent Document 1, item data (size of packaged item, product name, product number, etc.), set values ​​related to packaging conditions (set film length, packaging capacity, set temperature of sealing rollers, set heating temperature of sealing body, etc.), and current values ​​at the time of packaging of the packaged item (actual measured film length, actual measured heating temperature of vertical sealer, actual measured heating temperature of upper and lower sealing bodies in end sealing means, etc.) are stored in a memory means. However, in the packaged product quality recording device of Patent Document 1, the unique product information obtained by reading the barcodes (barcodes printed directly on the film for each individual packaged product as the film is transported) attached to the packages obtained after sealing and cutting is associated with the item data, set values ​​related to the packaging conditions, the current values, etc., and stored in a storage means as a unique quality record for each packaged product. Therefore, if a reading error occurs in the barcode, it is not possible to associate the unique product information with the item data, set values ​​related to the packaging conditions, the current values, etc., or an incorrect association is made, resulting in a problem that accurate traceability cannot be performed.

[0004] In this regard, Patent Document 2 (JP 2008-305121 A) discloses a product history information management system that includes a printing device that prints on a product the manufacturing date and time or manufacturing time of the product, and a storage device that stores production history information of the product on which the manufacturing date and time or manufacturing time is printed by the printing device in association with the manufacturing date and time or manufacturing time printed on the product, wherein the product has multiple pieces of production history information, and the storage device stores the manufacturing date and time or manufacturing time printed on the product in association with the multiple pieces of production history information held by the product. In the product history information management system of Patent Document 2, a container P filled with a beverage is identified (specified) by printing the filling time T1 and filling date D1 on the container P using a container printing device 30, and the filling time T1 and filling date D1 printed on the container P are associated with production history information such as the tank number (finishing tank number) that filled the container P with the beverage, lot number, line number, filling temperature, etc. However, in packaging machines and production systems that include packaging machines that produce packages in which a product (packaged product) is packed in packaging material, the time when the product (packaged product) was filled into the packaging material (such as a cylindrical packaging material) is not marked on the package, but rather identification information including a symbol that is different from time information such as date and time is marked on the package to identify (specify) each package, and therefore the product history information management system of Patent Document 2 cannot be applied.

[0005] In addition, Patent Document 3 (JP 2013-75712 A) describes a linked rotary conveying facility in which a plurality of rotary conveying devices, each having a plurality of conveyed object holding means provided on its periphery, are arranged in a row, and adjacent rotary conveying devices hand over and convey conveyed objects to each other in a linked manner. The linked rotary conveying facility is a traceability system for conveyed objects that is applied to conveyed objects, and includes a printing device that attaches an individual code to each conveyed object during conveyance by the linked rotary conveying facility, and information linking processing means that links information on each conveyed object that has been attached with an individual code by the printing device and each of the conveyed object holding means of the plurality of rotary conveying devices that have received the conveyed object. The present invention discloses a traceability system for transported items, which includes a rotary conveying device that forms a blow molding device for blow molding preforms for resin containers, a molded bottle inspection device that performs various inspections of the blow molded resin containers, a sterilization and cleaning device that sterilizes and cleans the resin containers, a filling device that fills the resin containers with a beverage, and a capping device that attaches a cap to the mouth of the resin container filled with a beverage, and a storage means that stores the linkage history information from the information linkage processing means in a database, and the transported items are resin containers for manufacturing beverage bottles, and the linked rotary conveying equipment is a rotary conveying device that forms each of the blow molding device, a molded bottle inspection device that performs various inspections of the blow molded resin containers, a sterilization and cleaning device that sterilizes and cleans the resin containers, a filling device that fills the resin containers with a beverage, and a capping device that attaches a cap to the mouth of the resin container filled with a beverage. In the transported goods traceability system of Patent Document 3, a printing device 11 marks each transported goods consisting of a resin container 1 with a laser, and individual codes such as a printing time, a line number, and a manufacturing number are attached. Linkage history information from an information linkage processing means 12 is compiled into a database and stored in a storage means 13. Linkage history information can be retrieved from the storage means 13 based on the individual code of the transported goods. The linkage history information includes the number of the mandrel that grips the preform (PFM) in the blow molding device 3, the numbers of all the grippers that grip the transported goods, the blow station number, the number of the preform, and the number of the blow station. The preform (PFM) body temperature, preform mouth temperature, primary molding air pressure, and secondary molding air pressure are compiled into a database and stored in the memory means 13, the inspection machine gripper number in the molded bottle inspection device 4 and multiple empty bottle inspection items are compiled into a database and stored in the memory means 13, and further, the sterilization nozzle number (No.), cleaning nozzle number, filling nozzle number, filling amount (load cell measurement value or flow measurement value), seaming device head number, seaming torque, etc. in the sterilization washing device 5, filling device 6, and cap seaming device 8 are compiled into a database and stored in the memory means 13. However, in packaging machines and production systems including packaging machines that produce packages in which products (packaged items) are wrapped in packaging material, devices are provided to perform each process along the way of transporting the continuous packaging material (film), and linked rotary conveying equipment as in Patent Document 3 is not configured in which multiple rotary conveying devices each having multiple transported item holding means provided on the periphery are lined up in order to transfer transported items between adjacent rotary conveying devices for linked transport, and link history information that can be extracted from individual codes attached to each transported item cannot be compiled into a database and stored in a memory means.

In addition, instead of the horizontal seal block upper temperature sensor 18t1 and the horizontal seal block lower temperature sensor 18t3 provided in the horizontal seal block 18a, a temperature sensor can be attached to the vertical center of the horizontal seal block 18a, and instead of the horizontal seal block upper temperature sensor 18t2 and the horizontal seal block lower temperature sensor 18t4 provided in the horizontal seal block 18b, a temperature sensor can be attached to the vertical center of the horizontal seal block 18b, and the upper horizontal seal temperature and lower horizontal seal temperature can be measured using the temperature sensor in the vertical center of the horizontal seal blocks 18a, 18b (in this case, the upper horizontal seal temperature and the lower horizontal seal temperature will be the same).

Based on the number of first packages stored (registered) in the product parameter table 22a of the memory unit 22 (details will be described later), the production history information generation unit 21d generates production history information of the package Pc in which the individual identification information printed on the film Fi by the identification information printing device 13a corresponds to the bag making processing conditions (feed amount of the film Fi, vertical sealing pressure, vertical sealing temperature, horizontal sealing pressure, upper horizontal sealing temperature, lower horizontal sealing temperature, etc.) measured by each bag making processing condition measuring means (length measuring device 16c, vertical sealing block pressure sensor 17p, vertical sealing block temperature sensors 17t1, 17t2, horizontal sealing block pressure sensor 18p, horizontal sealing block upper temperature sensors 18t1, 18t2, horizontal sealing block lower temperature sensors 18t3, 18t4, etc.).

[0032] The storage unit 22 includes a product parameter table 22a and a production history information table 22b. Figure 4 is an explanatory diagram explaining the configuration of the product parameter table 22a, where Figure 4(a) shows some of the parameters given to the driving equipment operation control unit 21a, and Figure 4(b) shows the number of packages among the parameters given to the production history information generation unit 21d. In the product parameter table 22a, the No., product name, production capacity, bag length, folding diameter, heater temperature (vertical, vertical preheat, horizontal front, horizontal back) as sealing conditions, pressure, time, etc. are registered. The No. is a number that identifies the product that the vertical pillow packaging machine 1 (vertical pillow packaging machine main body 10) produces, and is available in the range of 01 to 99. The No. and product name are entered from the product name registration screen displayed on the input display unit 34 of the operation panel 30, and transmitted from the transceiver unit 33 to the transceiver unit 23 via the communication line CL. The transmitted data is then received by the transceiver unit 23, processed by the calculation control unit 21, and registered in the product parameter table 22a in the memory unit 22. The numerical values ​​shown in Figure 4(a) for production capacity, bag length, folding diameter, heater temperature (vertical, vertical preheat, horizontal front, horizontal back), pressure, time, etc. are parameters, i.e., control information, whose values ​​indicate the conditions for operating the driving equipment (servo motor, heater, etc.) of the vertical pillow packaging machine main body 10.

The parameters (control information) are input from various parameter setting screens displayed on the input display unit 34 of the operation panel 30, such as a production capacity / bag specification setting screen, a heater temperature setting screen, and a sealing pressure / time setting screen, and are transmitted from the transceiver unit 33 to the transceiver unit 23 via the communication line CL. The parameters are received by the transceiver unit 23, processed by the calculation processing unit 21, and registered in the product parameter table 22a in the memory unit 22. As described above, the driving equipment operation control unit 21a controls the operation of the driving equipment of the vertical pillow packaging machine main body 10 (film feed servo motor 16M, vertical seal block servo motor 17M, horizontal seal block servo motor 18M, various heaters of the vertical seal section 17 and horizontal seal / cut section 18, etc.) based on the parameters of a specified number from the numbers (registration numbers) 01 to 99 registered in the product parameter table 22a. In FIG. 4(a), the "pressure-vertical" parameter (vertical sealing pressure) and the "pressure-horizontal" parameter (horizontal sealing pressure) are numerical values ​​expressed in kgf, but they may also be numerical values ​​expressed in N (Newtons).

[0033] Furthermore, as shown in FIG. 4(b), the number of packages, which is one of the parameters to be provided to the production history information generating unit 21d, is stored (registered) in the product parameter table 22a, and the number of packages is the number of first packages and the number of second packages. Among the first number of packages, the "film feed amount measurement position" represents the number of packages Pc corresponding to the conveyance distance of the film Fi from the position where the identification information printing device 13a prints the individual identification information on the film Fi (hereinafter referred to as the "individual identification information printing position") to the position where the length measuring device 16c measures the feed amount of the film Fi (hereinafter referred to as the "number of packages corresponding to the conveyance distance").

The "vertical seal temperature measurement position" represents the number of packages corresponding to the conveyance distance from the individual identification information printing position to the position where the vertical seal block temperature sensor 17p measures the vertical seal pressure. "Horizontal seal pressure measurement position" represents the number of packages corresponding to the conveying distance from the individual identification information printing position to the position where the horizontal seal block pressure sensor 18p measures the horizontal seal pressure, "upper horizontal seal temperature measurement position" represents the number of packages corresponding to the conveying distance to the position where the horizontal seal block upper temperature sensors 18t1, 18t2 measure the upper horizontal seal temperature, and "lower horizontal seal temperature measurement position" represents the number of packages corresponding to the conveying distance to the position where the horizontal seal block lower temperature sensors 18t3, 18t4 measure the lower horizontal seal temperature. The second number of packages represents the number of packages corresponding to the transport distance from the individual identification information printing position to the position where the date inspection device 13c inspects the quality of the date information printed on the film Fi. The number of first packages and the number of second packages stored in this product parameter table 22a are calculated by the package number calculation unit 31a of the computer 31 on the operation panel 30, or are input from the input display unit 34 of the operation panel 30.

[0034] FIG. 5 is an explanatory diagram illustrating the configuration of the production history information table 22b that stores the production history information generated by the production history information generating unit 21d. As shown in Figure 5, in the production history information table 22b, the individual identification information printed on the film Fi by the identification information printing device 13a is stored in correspondence with the film feed amount, vertical sealing pressure, vertical sealing temperature, vertical sealing time, horizontal sealing pressure, upper horizontal sealing temperature, lower horizontal sealing temperature, upper horizontal sealing time, lower horizontal sealing time, date inspection results, etc. The individual identification information consists of 12 alphanumeric characters, where the first letter ("A" in Figure 5) represents a symbol identifying the production factory, the next three digits ("001" in Figure 5) represent the machine number identifying the vertical pillow packaging machine 1, the next two digits ("01" in Figure 5) represent the "No." in the product parameter table 22a, and the next six digits ("000001" in Figure 5, etc.) are a consecutive number identifying each individual package Pc. The film feed amount is the feed amount of the film Fi measured by the length measuring device 16c, the vertical seal pressure is the pressure (kgf) measured by the vertical seal block pressure sensor 17p, the vertical seal temperature is the average value of the temperatures (°C) measured by the vertical seal block temperature sensors 17t1 and 17t2, the vertical seal time is the time (seconds) that the vertical seal blocks 17a and 17b are closed, that is, the time that the vertical seal block pressure sensor 17p detects the pressure, the horizontal seal pressure is the pressure (kgf) measured by the horizontal seal block pressure sensor 18p, and the upper horizontal seal The seal temperature is the average value of the temperatures (°C) measured by the horizontal seal block upper temperature sensors 18t1 and 18t2, the lower horizontal seal temperature is the average value of the temperatures (°C) measured by the horizontal seal block lower temperature sensors 18t3 and 18t4, the upper horizontal seal time and the lower horizontal seal time are the time (seconds) that the horizontal seal blocks 18a and 18b are closed, i.e., the time that the horizontal seal block pressure sensor 18p detects pressure, and the date inspection result is the inspection result of the date information by the date inspection device 13c, where ``11'' is good and ``12'' is bad. Figure 5 shows the production history information for the first three packages, No. "01" (product name "AAAA"), No. "02" (product name "BBBB"), and No. "03" (product name "CCCC"), all produced by packaging machine No. "001" in Factory "A."

[0035] The operation panel 30 includes a computer 31, a transmitting / receiving unit 33, and an input / display unit . The computer 31 is equipped with a calculation processing unit with a package number calculation unit 31a and a memory unit (not shown), and is equipped with a dedicated program corresponding to the vertical pillow packaging machine main body 10, and performs various processes and controls the operation panel 30 in an overall manner. The packaging number calculation unit 31a calculates the number of first packaging pieces and the number of second packaging pieces to be registered (stored) in the product parameter table 22a based on the length of the packaging pieces (bag length) entered from the product information input screen displayed on the input display unit 34 and registered in the product parameter table 22a. The transceiver unit 33 transmits various data (including the number of first packages and the number of second packages calculated by the package number calculation unit 31a) sent from the computer 31 to the transceiver unit 23 of the vertical pillow packaging machine control unit 20 via the communication line CL, and receives various data sent from the transceiver unit 23 via the communication line CL and sends it to the computer 31. The input display unit 34 has a touch panel display screen, and displays various screens created by dedicated programs installed in the computer 31. The screens displayed on the input display unit 34 include, for example, a basic screen that displays basic information (product name, production capacity, bag length, output, heater temperature, etc.) for production by the vertical pillow packaging machine main body 10, a product switching screen for switching the product produced by the vertical pillow packaging machine main body 10, a heater temperature setting change screen for setting or changing the heater temperatures of the vertical sealing unit 17 and the horizontal sealing and cutting unit 18, a table of contents screen, and a product information input screen for inputting packaging material (film) conditions (bag length, fold diameter, etc.), number of first packages, and number of second packages to be registered in the product parameter table 22a.

[0036] Here, calculation of the number of first packages and the number of second packages by the package number calculation unit 31a will be described. Now, the transport distance of the film Fi from the individual identification information printing position to the position where the length measuring device 16c measures the feed amount of the film Fi is L1a, the transport distance from the individual identification information printing position to the position where the vertical seal block pressure sensor 17p measures the vertical seal pressure is L1b, the transport distance from the individual identification information printing position to the position where the vertical seal block temperature sensors 17t1 and 17t2 measure the vertical seal temperature is L1c, the transport distance from the individual identification information printing position to the position where the horizontal seal block pressure sensor 18p measures the horizontal seal pressure is L1d, the transport distance to the position where the horizontal seal block upper temperature sensors 18t1 and 18t2 measure the upper horizontal seal temperature is L1e, and the transport distance to the position where the horizontal seal block lower temperature sensors 18t3 and 18t4 measure the lower horizontal seal temperature is L1f. Since the conveying distances L1a, L1b, L1c, L1d, L1e, and L1f are determined by the positions of the lift roller 13d and the slide roller 15c, the conveying distances L1a, L1b, L1c, L1d, L1e, and L1f corresponding to the positions of the lift roller 13d and the slide roller 15c are stored in advance in a memory unit or the like of the computer 31 of the operation panel 30. In addition, the positions of the lift roller 13d and the slide roller 15c are set for each type of product produced by the vertical pillow packaging machine 1 (the "No." registered in the product parameter table 22a) and are registered (stored) in the product parameter table 22a, etc. Thereby, the package number calculation unit 31a identifies the conveying distances L1a, L1b, L1c, L1d, L1e, and L1f corresponding to the product type stored in the memory unit or the like of the computer 31 for the products produced by the vertical pillow packaging machine 1, and divides the identified conveying distances L1a, L1b, L1c, L1d, L1e, and L1f by the package length (bag length) PL registered in the product parameter table 22a to calculate the number of packages corresponding to each conveying distance of the first package number. In addition, since the transport distance L2 from the individual identification information printing position to the position where the date inspection device 13c inspects the quality of the date information printed on the film Fi is a fixed distance determined by the installation positions of the identification information printing device 13a and the date inspection device 13c, the transport distance L2 is stored in advance in a memory unit or the like of the computer 31 of the operation panel 30. From this, the package number calculation unit 31a calculates the second package number by dividing the conveying distance L2 stored in the memory unit of the computer 31, etc., by the package length (bag length) PL registered in the product parameter table 22a.

[0037] [Generation and storage of production history information] Next, we will explain the operation of generating production history information that corresponds the individual identification information printed on the film Fi by the identification information printing device 13a with the bag making processing conditions measured by the bag making processing condition measuring means, etc., and storing the information in the production history information table 22b. Figure 6 is a timing chart showing the operation timing of each device (such as the identification information printing device 13a) during one cycle in which the vertical pillow packaging machine 1 produces one packaging body Pc, and shows an example of packaging body Pc No. "01" (product name "AAAA"). In Figure 6, the scale shown at the top indicates the cycle time, which is 100 divisions of 1 cycle (=0.75 seconds), TC1 indicates a timing chart of the identification information printing device 13a printing on the film Fi, TC2 indicates a timing chart of the date printing device 13b printing on the film Fi, TC3 indicates a timing chart of the date inspection device 13c inspecting the date printed on the film Fi, TC4 indicates a timing chart of the film feed section 16 feeding the film Fi, TC5 indicates a timing chart of the vertical sealing blocks 17a, 17b applying vertical seals to the film Fi, TC6 indicates a timing chart of the horizontal sealing blocks 18a, 18b applying horizontal seals to the film Fi, and t0 to t11 indicate the elapsed time during one cycle. Before the vertical pillow packaging machine 1 starts one cycle of operation, the printing control unit 21b of the vertical pillow packaging machine control unit 20 provides the top six digits of the individual identification information (a symbol identifying the production factory, a machine number, and No.) printed by the identification information printing device 13a of the vertical pillow packaging machine main body 10 based on information registered in the production history information table 22b, etc.

[0038] When one cycle starts, the film feeding servo motor 16M operates in the film feeding section 16 to feed the film Fi by the length of the package (bag length) (TC4, time t0 to t7). At this time, the length measuring device 16c operates to measure the feed amount of the film Fi and send the measured value to the vertical pillow packaging machine control unit 20. While the film Fi is being fed by the film feed unit 16, based on instructions from the printing control unit 21b, the identification information printing device 13a prints individual identification information on the film Fi (TC1, times t1 to t2), the date printing device 13b prints date information on the film Fi (TC2, times t3 to t4), and based on instructions from the inspection control unit 21c, the date inspection device 13c inspects the date printed on the film Fi (TC3, times t5 to t6). At this time, the identification information printing device 13a automatically generates the last six digits (serial number) of the individual identification information, prints out the 12-digit individual identification information added to the first six digits previously sent from the printing control unit 21b, and sends the printed individual identification information to the vertical pillow packaging machine control unit 20. As a result, the identification information printer 13a prints individual identification information, the last six digits of which vary consecutively, on the film Fi for each cycle, and individual identification information that differs for each package Pc is given to each package Pc. Further, the date inspection device 13c sends the inspection result as to whether the date information is good or bad to the vertical pillow packaging machine control unit 20. Next, while the film feed unit 16 is stopping feeding the film Fi, based on a command from the drive equipment operation control unit 21a, the servo motor 17M for the vertical seal block operates the opening and closing mechanism to open and close the vertical seal blocks 17a, 17b, and apply a vertical seal to the film Fi (TC5, time t8 to t9). At this time, the pressure detected by vertical seal block pressure sensor 17p is sent to vertical pillow packaging machine control section 20, and the temperatures detected by vertical seal block temperature sensors 17t1, 17t2 are sent to vertical pillow packaging machine control section 20. Next, the servo motor 18M for the horizontal seal block operates the opening and closing mechanism, opening and closing the horizontal seal blocks 18a, 18b, and applying a horizontal seal to the vertically sealed tubular film TFi (TC6, times t10 to t11), and the center of the horizontal seal portion is cut while the horizontal seal is being applied. At this time, the pressure detected by the horizontal seal block pressure sensor 18p is sent to the vertical pillow packaging machine control unit 20, and the temperatures detected by the horizontal seal block upper temperature sensors 18t1, 18t2 and the horizontal seal block lower temperature sensors 18t3, 18t4 are sent to the vertical pillow packaging machine control unit 20. After the horizontal seal is completed, one cycle is completed after a certain period of time has elapsed.

[0039] In this case, the production history information generating unit 21d corresponds the individual identification information sent to the vertical pillow packaging machine control unit 20 for each cycle to the bag making processing conditions (feed amount of film Fi, vertical sealing pressure, vertical sealing temperature, horizontal sealing pressure, upper horizontal sealing temperature, lower horizontal sealing temperature, etc.) based on the number of first packages stored in the product parameter table 22a, etc. Specifically, individual identification information (IDi) sent to the vertical pillow packaging machine control unit 20 in a certain cycle i is matched with the measured value of the feed amount of the film Fi sent from the length measuring device 16c to the vertical pillow packaging machine control unit 20 in a cycle (i+8) delayed by the number of packages corresponding to the conveying distance of the "film feed amount" stored in the product parameter table 22a ("8" for No. 01, product name AAAA). Similarly, the individual identification information (IDi) is associated with the measured value of the vertical seal pressure sent from the vertical seal block pressure sensor 17p to the vertical pillow packaging machine control unit 20 in a cycle (i+9) delayed by the number of packages corresponding to the conveying distance of the "vertical seal pressure measurement position" stored in the product parameter table 22a (No. 01, "9" for product name AAAA). Similarly, the individual identification information (IDi) is associated with the average value of the measured vertical seal temperature values ​​sent from the vertical seal block temperature sensors 17t1 and 17t2 to the vertical pillow packaging machine control unit 20 in a cycle (i+9) delayed by the number of packages corresponding to the conveying distance of the "vertical seal temperature measurement position" stored in the product parameter table 22a (No. 01, "9" for product name AAAA). Similarly, the individual identification information (IDi) is associated with the measurement value of the horizontal seal pressure sent from the horizontal seal block pressure sensor 18p to the vertical pillow packaging machine control unit 20 in a cycle (i+10) delayed by the number of packages corresponding to the conveying distance of the "horizontal seal pressure measurement position" stored in the product parameter table 22a ("10" for No. 01, product name AAAA). Similarly, the individual identification information (IDi) is associated with the average value of the measured upper horizontal seal temperature values ​​sent from the horizontal seal block upper temperature sensors 18t1 and 18t2 to the vertical pillow packaging machine control unit 20 in a cycle (i+10) delayed by the number of packages corresponding to the conveying distance of the "upper horizontal seal temperature measurement position" stored in the product parameter table 22a ("10" for No. 01, product name AAAA). Similarly, the individual identification information (IDi) is associated with the average value of the measured lower horizontal seal temperature values ​​sent from the horizontal seal block lower temperature sensors 18t3 and 18t4 to the vertical pillow packaging machine control unit 20 in a cycle (i+11) delayed by the number of packages corresponding to the conveying distance of the "lower horizontal seal temperature measurement position" stored in the product parameter table 22a (No. 01, "11" for product name AAAA).

[0040] In addition, the production history information generation unit 21d corresponds the individual identification information sent to the vertical pillow packaging machine control unit 20 for each cycle to the inspection results of the pass / fail of the date information based on the number of second packages stored in the product parameter table 22a. Specifically, the individual identification information (IDi) is associated with the inspection result of the pass / fail of the date information sent from the date inspection device 13c to the vertical pillow packaging machine control unit 20 in a cycle (i+2) delayed by the second package number (No. 01, for product name AAAA, "2") stored in the product parameter table 22a. In this way, based on the number of first packages and the number of second packages stored in the product parameter table 22a, the production history information generation unit 21d generates production history information by matching the individual identification information sent to the vertical pillow packaging machine control unit 20 for each cycle with the bag making processing conditions (feed amount of film Fi, vertical sealing pressure, vertical sealing temperature, horizontal sealing pressure, upper horizontal sealing temperature, lower horizontal sealing temperature, etc.) and the inspection results of the pass / fail date information, and stores the generated production history information in the production history information table 22b (see Figure 5).

[0041] [Reset individual identification information] Here, resetting of the individual identification information printed on the film Fi by the identification information printing device 13a will be described. In this embodiment, as described above, the individual identification information consists of 12 alphanumeric characters, with the first six alphanumeric characters being a symbol identifying the production factory, a machine number, and a No., and the last six digits being a consecutive number starting with 000001. This individual identification information is reset when a reset switch (not shown) provided on the vertical pillow packaging machine main body 10 is pressed to reset operating conditions, etc., or when the type of package produced by the vertical pillow packaging machine 1 is changed, or when the date or time at which the vertical pillow packaging machine 1 produces the package is changed. This saves the worker the trouble of resetting the individual identification information, prevents mistakes in resetting the individual identification information, and allows the individual identification information to be reset at the right time. In this embodiment, when the type of package produced by the vertical pillow packaging machine 1 (the product name specified by the "No." stored in the product parameter table 22a) is changed, the individual identification information is reset. When the individual identification information is reset, the identification information printing device 13a generates individual identification information by adding the lower six digits of information consisting of a consecutive number starting with "000001" to the upper six digits of information (a symbol identifying the production factory, machine number, No.) given by the printing control unit 21b of the vertical pillow packaging machine control unit 20, and prints the information on the film Fi.

[0042] [Packaging production system] Next, the packaging production system of the present invention will be described.

The belt conveyor 45 is equipped with a conveying belt, drive rollers, drive motor, etc., and is located between the vertical pillow packaging machine 1' and the boxing device 43. The belt conveyor 45 places the packaged body Pc discharged from the vertical pillow packaging machine 1' on the conveying belt and transports it to the boxing device 43. The roller conveyor 46 is equipped with conveying rollers, a drive motor, etc., and is provided between the packing device 43 and a discharging device (not shown). It transports the packaged cardboard boxes D11 discharged from the packing device 43 to the sealing machine 44, and further transports the sealed cardboard boxes D12 discharged from the sealing machine 44 to the discharging device.

[0044] The management computer 50 is equipped with an arithmetic control unit 51, a memory unit 52 and a transmission / reception unit 53, and the transmission / reception unit 53 is connected to the vertical pillow packaging machine control unit 20', the package inspection device 41 and the case packing device control unit 43a via communication lines CL1, CL2, and CL3. The calculation control unit 51 includes a production history information generating unit 51 a and controls the management computer 50 in an integrated manner. The production history information generation unit 51a generates first production history information for the packaging body Pc, which corresponds the individual identification information printed on the film Fi by the identification information printing device 13a of the vertical pillow packaging machine main body 10 with the bag making processing conditions (feed amount of film Fi, vertical sealing pressure, vertical sealing temperature, horizontal sealing pressure, upper horizontal sealing temperature, lower horizontal sealing temperature, etc.) measured by each bag making processing condition measuring means (length measuring device 16c, vertical sealing block pressure sensor 17p, vertical sealing block temperature sensors 17t1, 17t2, horizontal sealing block pressure sensor 18p, horizontal sealing block upper temperature sensors 18t1, 18t2, horizontal sealing block lower temperature sensors 18t3, 18t4, etc.) based on the number of first packages stored (registered) in the product parameter table 22a of the memory unit 22 of the vertical pillow packaging machine control unit 20' (see Figure 4(b)). In addition, the production history information generation unit 51a generates second production history information for the packaging body Pc, which corresponds the individual identification information printed on the film Fi by the identification information printing device 13a to the inspection results of the packaging body inspection device 41 and the time when the packaging body Pc was packed by the packing device 43, based on the first movement time and the second movement time (described later) stored in the packaging body movement time table 52a of the memory unit 52.

[0045] The memory unit 52 includes a package movement time table 52a and a production history information table 52b. FIG. 9 is an explanatory diagram for explaining the configuration of the package movement time table 52a. The packaging material movement time table 52a stores the first movement time (seconds) and the second movement time (seconds) for each "No." (product name) registered in the product parameter table 22a of the memory unit 22 of the vertical pillow packaging machine control unit 20'. The first movement time represents the time it takes for the packaging material Pc to move from the time the packaging material discharge section 19 of the vertical pillow packaging machine main body 10 discharges the packaging material Pc (from the time the packaging material Pc is placed on the belt conveyor 19a of the packaging material discharge section 19) to the time the packaging material inspection device 41 reaches a position where it inspects the packaging material Pc. The second movement time indicates the time it takes for the package Pc to move from the position where the package inspection device 41 inspects the package Pc to the position where the packing device 43 packs the package Pc into a box. The first movement time and the second movement time are fixed values ​​determined by the conveying speed of the belt conveyor 45, etc., which are set for each type of packaging material produced by the vertical pillow packaging machine 1' (a packaging material identified by a "No." (product name) registered in the product parameter table 22a), and are input in advance from an input section (not shown) of the management computer 50 and registered (stored) in the packaging material movement time table 52a.

[0046] [Generation and storage of production history information by management computer 50] Next, the operation of the management computer 50 will be described, in which it generates first production history information that associates the individual identification information printed on the film Fi by the identification information printing device 13a with the bag making processing conditions measured by the bag making processing condition measuring means, etc., and also generates second production history information that associates the individual identification information with the inspection results of the package inspection device 41 and the time when the package Pc was packed by the packing device 43, and stores the generated first production history information and second production history information in the production history information table 52b as production history information for the package Pc. As described above, the production history information generating unit 51a generates the first production history information and the second production history information, but the operation of the production history information generating unit 51a to generate the first production history information is the same as the operation of the production history information generating unit 21d shown in FIG. 3 to generate production history information that corresponds the individual identification information sent to the vertical pillow packaging machine control unit 20 for each cycle with the bag making processing conditions (feed amount of film Fi, vertical sealing pressure, vertical sealing temperature, horizontal sealing pressure, upper horizontal sealing temperature, lower horizontal sealing temperature, etc.) based on the first package number stored in the product parameter table 22a, and the portion of the production history information table 52b that stores the first production history information generated by the production history information generating unit 51a is the same as the production history information table 22b shown in FIG. 5. In addition, the production history information generation unit 51a identifies individual identification information (IDi) associated with a package Pc that is transversely sealed and cut at the transverse sealing and cutting unit 18 and falls onto the belt conveyor 19a, based on the number of packages corresponding to the conveying distance of the "lower transverse seal temperature measurement position" stored in the product parameter table 22a, measures the time Ti at which the falling package Pc is placed on the belt conveyor 19a using a timer (not shown) in the vertical pillow packaging machine control unit 20', and associates the individual identification information (IDi) with the time Ti. At the time (Ti+ΔT1) obtained by adding the first package movement time ΔT1 stored in the package movement time table 52a to this time Ti, the package with the individual identification information (IDi) reaches the position of the package inspection device 41, and associates the individual identification information (IDi) with the inspection results obtained by the package inspection device 41 at this time. Furthermore, since the package of individual identification information (IDi) reaches the packing position of the packing device 43 at the time (Ti+ΔT1+ΔT2) obtained by adding the second package movement time ΔT2 stored in the package movement time table 52a to the time (Ti+ΔT1) when the package inspection device 41 inspected the package of individual identification information (IDi), the production history information generation unit 51a associates the time (Ti+ΔT1+ΔT2) with the individual identification information (IDi) as the package packing time. In this way, the production history information generation unit 51a generates second production history information that corresponds the individual identification information (IDi), the inspection results of the package inspection device 41, and the time when the package Pc was packed by the packing device 43, and stores the second production history information in the production history information table 52b.

[0047] FIG. 10 is an explanatory diagram illustrating the configuration of a portion of the production history information table 52b in which the second production history information is stored. As shown in FIG. 10, in the portion of the production history information table 52b where the second production history information is stored, the individual identification information printed on the film Fi by the identification information printing device 13a is stored in correspondence with the package discharge time, package inspection result, and package packing time. The package discharge time is the time when the package Pc that has been horizontally sealed and cut in the horizontal sealing and cutting section 18 falls onto the conveyor belt 19a, and the package packing time is the time when the package Pc reaches the packing position in the packing device 43. The six-digit number indicating the time represents the hour, minute, and second, so "083020" represents 8:30 minutes and 20 seconds. The package inspection result is the result of inspection by the package inspection device 41 as to whether the appearance of the package Pc is good or bad, with "11" being good and "12" being bad. FIG. 10 shows the production history information of the package identified by the individual identification information for which the production history information (first production history information) is shown in FIG.
