Description

The present invention relates to an operating condition recovery device and packaging-related device that recovers the operating conditions of various driving devices in packaging-related devices such as pillow packaging machines, wrapping packaging machines, overwrapping packaging machines, box making machines, box filling machines, and sealing machines.

Packaging-related equipment includes pillow packaging machines that sequentially fill cylindrically formed packaging material with packaged products and then seal and cut the product to produce a package; wrapping packaging machines that package the products by wrapping them in cut packaging material; overwrap packaging machines that cover one or more packaged products with packaging material; box-making machines that make boxes to store the products; box-filling devices that pack the products into boxes; and sealing machines that seal boxes containing the products. Pillow packaging machines include vertical pillow packaging machines that feed the packaging material up and down (vertically) to fill it with packaged products, and horizontal pillow packaging machines that feed the packaging material left and right (horizontally) to fill it with packaged products.
In such various packaging-related devices, an operator sets operating conditions for driving devices such as motors and heaters for each product to be produced, and the product is produced.
Specifically, in vertical pillow packaging machines and horizontal pillow packaging machines, the operating conditions of the driving equipment are set, for example, the number of bags produced per unit time, the length of each bag, and the heater temperature (sealing temperature).
In addition, in packaging-related devices, adjustment conditions for the adjustment equipment include, for example, the left-right position of the rolled packaging material, the left-right position of the date printing device, the position of the vertical seal block of a vertical pillow packaging machine, the angle of the tension arm (tension roller angle) of a horizontal pillow packaging machine, and the position of the tension roller (tension roller distance).
However, the setting of operating conditions and adjustment conditions (hereinafter referred to as "operating conditions, etc.") in packaging-related devices is often performed based on the experience and intuition of an operator, resulting in problems such as the need for time to set optimal operating conditions, the inability to reset operating conditions, etc. once they have been set, or the need for time to reset them.
For this reason, various proposals have been made regarding the setting of operating conditions, etc. in packaging-related devices.

For example, Patent Document 1 (JP Patent Publication 8-198206A) discloses a packaging device that uses a pair of heat seal rolls to heat seal a film unwound from an original roll, the packaging device including a braking means provided on a rotating shaft that supports the original roll, a film tension detection means that detects a tension value of the film, a tension control means that controls the braking means so that the tension value is approximately constant, a production condition setting means (touch panel 22) that inputs production conditions corresponding to the packaging form of each product type, a tension control means (control circuit 18) that calculates a reference tension value adapted to the packaging form of each product type based on the production conditions and controls the tension control means, and a storage means (backup RAM 19) that stores the reference tension value in a non-volatile manner.
In the packaging device (filling and packaging machine) of Patent Document 1, when the production conditions are input into the production condition setting screen of the touch panel 22, the CPU 15 of the control circuit 18 calculates and processes the tension value t of the film F, and the tension control means controls the braking means using this as a reference tension value. For example, if heat sealing is not performed well and correction to the reference tension value t is required, the CPU 15 performs, for example, addition or subtraction of the correction value input by the touch panel 22 to the reference tension value t and outputs the corrected reference tension value t to the tension control means. If correction to the reference tension value t is not required, this reference tension value t is stored in the backup ROM 19. Therefore, when the filling and packaging machine is operated repeatedly using the same packaging form, it is only necessary to read out the reference tension value t from the backup ROM 19, thereby shortening the setup time.
However, in the packaging device of Patent Document 1, what is stored in the storage means (backup RAM) is the production conditions and the reference tension value, and not various operating conditions of packaging-related devices.

Incidentally, in packaging-related equipment, even for the same type of product, it is not possible to always produce the product under the same operating conditions, etc. For example, it is necessary to change the operating conditions, etc. in response to changes in the environment, such as temperature and humidity, and in terms of production efficiency, it may be desirable to frequently change the operating conditions, etc. during product production and ultimately reset them to the original operating conditions, etc., or to operating conditions, etc. that were set at a specific time in the past.
Furthermore, if a product defect occurs during production, an inexperienced worker may not be able to determine how to change the operating conditions, etc. to resolve the product defect, which may result in production disruption.
Furthermore, when maintenance or the like is performed on a packaging-related device, it may be necessary to change many of the operating conditions after the maintenance from those before the maintenance, and it may take time to set the operating conditions.
In such a case, even if various operating conditions, etc. of the packaging-related device are stored in the storage means (backup RAM) of Patent Document 1 and made available for reading, it is not possible to deal with the above-mentioned case because what is stored in the storage means (backup RAM) is the operating conditions, etc. that have been set once or the corrected operating conditions, etc.

Patent Document 2 (JP 2012-176771 A) discloses a stretch wrapping device that includes an input section for packaged items into which packaged items are input, an output section for packaged items from which the packaged items are output in a packaged state, a plurality of electrical consumption components for packaging and outputting the inputted packaged items, and a control section for controlling the electrical consumption components, and a human body detection means is disposed near the input section for packaged items and/or the output section for packaged items to detect the presence of a person who inputs the packaged items, and the control section has a mode switching section that switches between a normal mode and a first standby mode that consumes less power than the normal mode based on a detection result by the human body detection means (Claim 1 in Patent Document 2), and a backup execution section that backs up master data (product master, tray master, etc.) that is basic data for setting up the stretch wrapping device 1 in the first standby mode and the second standby mode, and that can be set to the master data that was backed up last time in the event of a breakdown in the stretch wrapping device (paragraphs [0080] and [0086] in Patent Document 1).
However, the backup execution unit of the stretch wrapping device in Citation 2 backs up information (master data) about products and trays, and not the operating conditions of wrapping-related devices, etc.
Even if a packaging-related device were provided with a backup execution unit similar to that of the stretch wrapping device in Cited Document 2 to back up operating conditions, etc., it would only be able to set the previous operating conditions, etc., and if the previous operating conditions, etc. are not optimal, it would be necessary to change the set operating conditions, etc. to optimal ones, resulting in the same problems as when operating conditions, etc. are stored in the memory means (backup RAM) of Patent Document 1.

The operation control unit 21a controls the operation of the driving equipment of the vertical pillow packaging machine main body 10, such as the motor of the packaging material feed unit 16 and various heaters of the vertical sealing unit 17 and the horizontal sealing/cutting unit 18, based on the parameters registered in the product parameter table 22a of the memory unit 22 or the parameters sent from the transmission/reception unit 23 for the product set on the operation panel 30.
The adjustment equipment control unit 21b controls the operation of the adjustment equipment of the vertical pillow packaging machine main body 10, such as the moving mechanism of the date printing device 13a, the lifting mechanism of the lifting roller 13b, and the slide mechanism of the slide roller 15c, for the product set on the operation panel 30, based on the parameters registered in the product parameter table 22a in the memory unit 22 or the signal sent from the transmission/reception unit 23.
The calculation control unit 21 also includes a measurement information management unit and a production information management unit (neither of which are shown), and controls the vertical pillow packaging machine control unit 20 in an integrated manner.
The measurement information management section of the calculation control section 21 acquires information measured by measuring equipment installed in the vertical pillow packaging machine main body 10, such as temperature sensors that measure the temperatures of various heaters in the vertical sealing section 17 and the horizontal sealing/cutting section 18, and sends it to the transmission/reception section 23.
The production information management section of the calculation control section 21 obtains information regarding the produced packaging bodies Pc, such as the output (production quantity of packaging bodies Pc), the quantity of empty bags, operating time, etc., from the vertical pillow packaging machine main body 10, and sends it to the transmission/reception section 23 while also registering it in a production information table (not shown) in the memory section 22.

The memory unit 22 stores a product parameter table 22a, a production information table (not shown), etc., and the production information table registers production results such as output, empty bags, lost bags, operating rate, operating time, stoppage time, and waiting time for products that have actually been produced.
FIG. 3 is an explanatory diagram for explaining the configuration of the product parameter table 22a.
In the product parameter table 22a, the following items are registered: No. (registration number), product name, production capacity, bag length, folding diameter, heater temperature (vertical left, vertical right, horizontal front, horizontal rear), date printer position, lift roller position, slide roller position, vertical heater block position, etc. However, the item names themselves, such as "No. (registration number)", "product name", "production capacity", "bag length", "folding diameter", "heater temperature (vertical left, vertical right, horizontal front, horizontal rear)", "date printer position", "lift roller position", "slide roller position", and "vertical heater block position", are not registered, and only the parts excluding the item names are registered.
The registration number is a number that identifies the product produced by the vertical pillow packaging machine 1 (vertical pillow packaging machine main body 10), and is available in the range of 01 to 99.
The number and the product name are inputted from a product name registration screen (not shown) displayed on the input display unit 34 of the operation panel 30, and are transmitted from the transmitting/receiving unit 31 to the transmitting/receiving unit 21 of the vertical pillow packaging machine control unit 20 via the communication line CL. The transmitting/receiving unit 21 receives the product number and the product name and registers them in the product parameter table 22a of the storage unit 22.

The numerical values for production capacity, bag length, folding diameter, and heater temperature (vertical left, vertical right, horizontal front, horizontal back) are parameters (control information) whose values indicate the operating conditions for operating the driving equipment (motor, heater, etc.) of the vertical pillow packaging machine main body 10.
For example, the "production capacity" parameter "80" means "80 bpm" (bpm is the number of bags produced per minute), that is, 80 bags are produced per minute; the "bag length" parameter "250" means "250 mm", that is, the length of one bag is 250 mm; the "heater temperature, vertical left" parameter "160" means "160°C", that is, the temperature of the left vertical heater is "160°C."
The numerical values of the date printing device position, lifting roller position, slide roller position, and vertical heater block position are parameters (control information) whose values indicate the adjustment conditions for operating the movement mechanism of the date printing device 13a, the lifting mechanism of the lifting roller 13b, the slide mechanism of the slide roller 15c, and the movement mechanism of the vertical seal blocks 17a and 17b, which are adjustment devices for the vertical pillow packaging machine main body 10.
For example, "20,""30,""50," and "15" shown in the row of the product name "AAAA" mean that the left-right position of the date printing device 13a, the position of the lifting roller 13b, the position of the slide roller 15c, and the positions of the vertical seal blocks 17a and 17b of the product name "AAAA" are 20 mm, 30 mm, 50 mm, and 15 mm, respectively.

The parameters 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 and a heater temperature setting screen (neither shown), and are transmitted from the transceiver unit 33 via the communication line CL to the transceiver unit 23 of the vertical pillow packaging machine control unit 20, received by the transceiver unit 23, and registered in the product parameter table 22a of the memory unit 22.
As described above, the operation control unit 21a controls the operation of the driving devices of the vertical pillow packaging machine main body 10, such as the motor of the packaging material feed unit 16 and various heaters of the vertical sealing unit 17 and the horizontal sealing and cutting unit 18, based on parameters related to the operating conditions of a specified number from among the numbers (registration numbers) from 01 to 99 registered in the product parameter table 22a.
In addition, the adjustment equipment control unit 21b operates the adjustment equipment of the vertical pillow packaging machine main body 10, such as the movement mechanism of the date printing device 13a, the lifting mechanism of the lifting roller 13b, the slide mechanism of the slide roller 15c, and the movement mechanism of the vertical sealing blocks 17a and 17b, and moves the date printing device 13a, the lifting roller 13b, the slide roller 15c, and the vertical sealing blocks 17a and 17b to the parameter positions registered in the product parameter table 22a.
In addition, instead of operating adjustment equipment such as the movement mechanism of the date printing device 13a based on parameters registered in the product parameter table 22a, the adjustment equipment control unit 21b may operate adjustment equipment such as the movement mechanism of the date printing device 13a based on a signal input from an operation panel 30 or the like by an operator.
In this case, the parameters related to the adjustment conditions registered in the product parameter table 22a are simply displayed on the input display unit 34 or the like of the operation panel 30, and the worker inputs a signal to operate the adjustment device from the input display unit 34 or the like in accordance with the parameters displayed on the input display unit 34 or the like, or manually adjusts the adjustment device.

[Operation Panel 30]
As shown in FIG. 1, the operation panel 30 includes a computer 31, a transmitting/receiving unit 33, and an input display unit .
The computer 31 is equipped with an arithmetic processing unit and a memory unit, and is equipped with a dedicated program corresponding to the vertical pillow packaging machine main body 10, and performs various processes and controls the vertical pillow operation panel 30 in an integrated manner.
The transceiver unit 33 transmits various data sent from the computer to the transceiver unit 23 of the vertical pillow packaging machine control unit 20 via the communication line CL, and receives various data transmitted from the transceiver unit 23 of the vertical pillow packaging machine control unit 20 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 the display screen creation unit 31e.

As described above, the arithmetic processing unit of the computer 31 includes the backup data generating unit 31a, the backup data information generating unit 31b, the backup data saving unit 31c, the backup data selection output unit 31d, the parameter comparison output unit 31e, and the display screen creating unit 31f.
The backup data generation unit 31a generates multiple backup data for all parameters by generating backup data (copy data of all parameters) for all parameters of all products registered in the product parameter table 22a multiple times within a specified period.
Specifically, periodically, for example, once a week (for example, every Friday), after the vertical pillow packaging machine 1 finishes the production of the products scheduled for that day, the backup data generating unit 31a generates backup data of all parameters either automatically or by the operator. In this way, the backup data generating unit 31a generates backup data of all parameters four to five times a month.
In addition, the backup data generation unit 31a generates backup data of all parameters at irregular intervals, for example, when parameters are changed after maintenance or repair of the vertical pillow packaging machine 1, either by operation of an operator or automatically.
Furthermore, for example, when a product defect occurs during the production of a specific product and the product defect is resolved by a specialist or other person other than the operator changing the parameters, the backup data generation unit 31a generates backup data of the changed parameters of the specific product (specific parameters) either by operation of the operator or automatically.
The backup data information generation unit 31b generates backup data information that identifies each of the multiple backup data generated by the backup data generation unit 31a, such as date information such as the year, month, and day of generation in the case of backup data generated periodically, date information of generation and reason information such as maintenance, repair, etc. in the case of backup data generated irregularly, and product information, date information, and parameter change reason information in the case of backup data of a specific parameter.
The backup data information (date information, etc.) generated by the backup data information generating section 31b is displayed on the input display section .

The backup data storage unit 31c stores the backup data generated by the backup data generation unit 31a and the backup data information generated by the backup data information generation unit 31b for the backup data each time the backup data generation unit 31a generates backup data for all parameters or backup data for a specific parameter.
The backup data storage unit 31c stores the backup data of all parameters generated irregularly by the backup data generation unit 31a and the backup data information.
Furthermore, the backup data storage unit 31c stores the backup data of the specific parameters generated by the backup data generation unit 31a and the backup data information.
Among the backup data and backup data information stored in the backup data storage unit 31c, the backup data and backup data information outside the predetermined period are deleted.
As a result, only backup data and backup data information generated during a predetermined period are stored in the backup data storage unit 31c.
The backup data selection output unit 31d selects one piece of backup data from among the multiple pieces of backup data stored in the backup data storage unit 31c, sends the selected one piece of backup data to the transmission unit 33, and this one piece of backup data is sent to the vertical pillow packaging machine control unit 20 via the communication line CL, so that the parameters registered in the product parameter table 22a are changed to this one piece of backup data.
The parameter comparison output unit 31e compares one backup data selected by the backup data selection output unit 31d with the parameters registered in the product parameter table 22a for the product currently being produced by the vertical pillow packaging machine 1, and outputs the comparison result (e.g., the name of the differing parameter, the numerical value of the backup data, and the numerical value of the parameter registered in the product parameter table 22a) (e.g., displaying it on the input display unit 34).
The display screen creation unit 31e creates various screens to be displayed on the input display unit 34, such as various parameter setting screens (production capacity/bag specification setting screen, heater temperature setting screen, etc.), a screen displaying the production results of the vertical pillow packaging machine 1 stored in the production information table of the memory unit 22, and a screen displaying the backup data information generated by the backup data information generation unit 31b.

[Operation of the operating condition restoration device]
FIG. 4 is a flowchart showing the operation of the operating condition recovery device of the vertical pillow packaging machine 1 to generate and store backup data.
The backup data generating and saving operations of the operating condition restoring device will be described below with reference to the drawings.
First, in the arithmetic processing unit of the computer 31, a command to generate backup data is issued to the backup data generating unit 31a (S1).
The command to generate this backup data is given periodically, for example once a week (for example, every Friday), after the vertical pillow packaging machine 1 has finished producing the products scheduled for that day, by the operator operating the operation panel 30, or automatically.
In addition, the command to generate this backup data is issued irregularly, for example, when parameters are changed after maintenance or repair of the vertical pillow packaging machine 1, by the operator operating the operation panel 30, or automatically.
Furthermore, the command to generate this backup data is issued by the operator operating the operation panel 30 or automatically, for example, when a product defect occurs during the production of a specific product and a specialist other than the operator changes parameters to resolve the product defect.
Next, the backup data generation unit 31a issues a backup data transmission command to the vertical pillow packaging machine control unit 20 via the transmission/reception unit 33 and the communication line CL, and backup data (copy data of all parameters) of all parameters (all parameters) of all products registered in the product parameter table 22a, or backup data (copy data of specific parameters) of a specific product's parameters (specific parameters) is transmitted to the computer 31 via the transmission/reception unit 23 and the communication line CL and imported into the computer 31, thereby generating backup data by the backup data generation unit 31a (S2).

Thereafter, the backup data information generation unit 31b generates backup data information for identifying the backup data generated by the backup data generation unit 31a, such as date information such as the date of generation if the backup data is generated periodically, date information of generation and information on the reason for maintenance, repair, etc. if the backup data is generated irregularly, and product information, date information, and information on the reason for parameter change if the backup data is of a specific parameter (S3).
Next, the backup data generated by the backup data generation unit 31a (backup data of all parameters or backup data of specific parameters transmitted from the vertical pillow packaging machine control unit 20 to the computer 31) is associated with the backup data information generated by the backup data information generation unit 31b, and this backup data and the backup data information are stored in the backup data storage unit 31c (S5).
Finally, among the backup data and backup data information stored in the backup data storage unit 31c, the backup data and backup data information outside the predetermined period are deleted (S5), and the process ends.
Specifically, if the predetermined period is the most recent month, backup data and backup data information that have been stored in the backup data storage unit 31c for more than one month will be deleted, and only backup data and backup data information stored in the most recent month (backup data generated once a week during the most recent month, backup data generated irregularly, and backup data information corresponding to these backup data) will be stored in the backup data storage unit 31c.

FIG. 5 is a flowchart showing the operation of changing the parameters registered in the product parameter table 22a using the backup data stored by the operating condition restoration device of the vertical pillow packaging machine 1.
The parameter changing operation of the product parameter table 22a by the operating condition restoring device will be described below with reference to FIG.
First, the display screen creation unit 31e creates a screen for displaying backup data information and displays it on the input display unit 34, and the backup data information about the backup data stored in the backup data storage unit 31c is displayed on the input display unit 34 (S11).
FIG. 6 is a screen configuration diagram showing an example of a screen that displays backup data information. In the figure, 40 denotes a screen, and 41 denotes a button.
As shown in Figure 6, the top of screen 40 displays the words "Backup Data Information" and the date (current date) "December 1, 2022", and below that, the backup date (the date the backup was made), backed up parameters (type of backed up parameters), and reason (reason for backup) are displayed in list format, with check boxes displayed to the left of each list, and a parameter change button 41 is displayed in the bottom right of screen 40.
In the example shown in Figure 6, a total of six backup data are stored in the backup data storage unit 31c: backup data of all parameters generated on November 25, 2022, November 18, 2022, November 15, 2022, November 11, 2022, and November 4, 2022, as well as backup data of parameters for product "AAAA" generated on November 9, 2022.

FIG. 7 is a screen configuration diagram showing another example of the screen for displaying backup data information, in which 50 denotes a screen and 51 denotes a button.
As shown in Figure 7, the top of screen 50 displays the words "Backup Data Information" and the date (current date) "December 1, 2022", and below that, each day of November 2022, the most recent January, is displayed in a different row for each week (a so-called monthly calendar display), and the date on which the backup data was generated is displayed surrounded by a shape.
Specifically, the days when backup data of all parameters was generated periodically (4th, 11th, 18th, 25th) are surrounded by circles, the day when backup data of all parameters was generated irregularly (15th) is surrounded by a square with the reason for generating the backup data "maintenance", and the day when backup data of parameters of a specific product was generated (9th) is surrounded by a triangle with the product name "AAAA" and the reason for generating the backup data "faulty seal" are displayed.

Next, when an operator operates the device to select one piece of backup data information from the backup data information displayed on the input display unit 34, the backup data selection output unit 31d selects backup data (one piece of backup data) corresponding to the one piece of backup data information from the multiple pieces of backup data stored in the backup data storage unit 31c (S12).
Specifically, when the worker touches any one of the multiple pieces of backup data information displayed on the screen of the input display unit 34, the touched backup data information is selected.
FIG. 8 is an explanatory diagram for explaining a state in which one piece of backup data information is selected on the screen 40. As shown in FIG.
Figure 8 shows that the second item, "November 18, 2022, All Parameters, Regular," has been selected from the list of backup data information displayed on screen 40, with the selected row displayed in a colored band and a check mark in the check box on the left.
FIG. 9 is an explanatory diagram for explaining a state in which one piece of backup data information is selected on the screen 50. As shown in FIG.
FIG. 9 shows a state in which the number "18" surrounded by a circle has been selected from the calendar displayed on the screen 50, and the selected circle is filled in gray.
Then, when the operator touches the button 41 on the screen 40 or the button 51 on the screen 50, the backup data selection output section 31d selects the backup data of all parameters generated on November 18th.

Next, the backup data selected by the backup data selection output unit 31d is sent to the transmitting/receiving unit 33 and transmitted to the vertical pillow packaging machine control unit 20 via the communication line CL (S13).
Specifically, the backup data of all parameters generated on November 18th is transmitted from the operation panel 30 to the vertical pillow packaging machine control unit 20 via the communication line CL.
The backup data transmitted to the vertical pillow packaging machine control unit 20 in this manner is received by the transmission/reception unit 23 and sent to the calculation control unit 21, where all parameters registered in the product parameter table 22a are changed to one backup data, specifically, the backup data of all parameters generated on November 18th (S14), and the processing is terminated.
In addition, when backup data of parameters of a specific product, for example, backup data of parameters of product "AAAA" generated on November 9, 2022, is selected as one backup data in S12, the selected backup data is sent to the vertical pillow packaging machine control unit 20, and the parameters of product "AAAA" registered in the product parameter table 22a are changed to the sent backup data of parameters of product "AAAA".
In addition, when backup data of all parameters is selected as one backup data in S12, instead of changing all parameters registered in the product parameter table 22a to backup data, only the parameters of the specified product may be changed to backup data.
In this case, a list of all products registered in the product parameter table 22a may be displayed on the input display section 34 of the operation panel 30, and the operator may specify or select the product whose parameters are to be changed.

In addition, in S12, for the product currently being produced by the vertical pillow packaging machine 1, the parameter comparison output unit 31e may compare one of the backup data selected by the backup data selection output unit 31d with the parameters registered in the product parameter table 22a, and display the comparison result on the input display unit 34.
Specifically, if the product currently being produced by vertical pillow packaging machine 1 is "AAAA" and backup data selection output unit 31d selects the backup data of all parameters generated on November 18th, then, through operation by the operator, parameter comparison output unit 31e will compare the backup data of the parameters of product "AAAA" generated on November 18th with the parameters of product "AAAA" registered in product parameter table 22a, and as a result of the comparison, will display the parameter names where the numerical values of the parameters differ and the numerical values of those parameters, for example, if the differing parameter name is "heater temperature, vertical left", the numerical value of the backup data is "165", and the numerical value of the parameter registered in product parameter table 22a is "160", then "Heater temperature, vertical left on November 18th: 165 degrees, current heater temperature, vertical left: 160 degrees" will be displayed on input display unit 34.
This allows the worker to know which parameters, among those set for the product currently being produced, differ from the backup data and how.
In this case, the process from S13 onwards may not be carried out, and the heater temperature setting screen may be displayed on the input/display unit 34 by the operator's operation, and the heater temperature parameters may be changed.
