Description

The present invention relates to an alarm screen that displays an alarm indicating an operational abnormality in packaging-related devices such as pillow packaging machines, wrapping packaging machines, overwrapping packaging machines, and boxing 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; and boxing devices that box products. Pillow packaging machines include vertical pillow packaging machines that feed the packaging material up and down (vertically) to fill the packaged products, and horizontal pillow packaging machines that feed the packaging material left and right (horizontally) to fill the packaged products.
In such various packaging-related devices, various sensors etc. are attached to check whether the device is operating normally, etc., but if the device is not detected as operating normally due to a failure of the various sensors or a malfunction of the drive unit, an alarm indicating an operation abnormality (hereinafter referred to as an "abnormality alarm") is issued, and the worker takes measures such as performing operations and tasks in accordance with the resolution method described in the device manual etc., so that the device is operating normally and this is detected normally by the sensors etc.
Various proposals have been made to enable an operator to deal with an abnormality alarm as quickly and appropriately as possible.

For example, Patent Document 1 (JP Patent Publication No. 9-2480) discloses a packaging device with a display means which includes a packaging device, an abnormality detection means which detects abnormalities in the packaging device, and a database in which manual data required to recover from an abnormal state is stored in association with the abnormal state, and in which a control unit refers to the database based on output from the abnormality detection means when an abnormality occurs, and is capable of outputting the manual data required for recovery.
However, in the packaging device of Patent Document 1, the contents of the manual required for recovery from the abnormal state are simply displayed on the display means, and the worker must perform various operations and tasks according to the contents of the displayed manual. For example, when an abnormality is detected from a sensor at a specific location, in order to confirm whether the abnormality is due to a sensor failure, it is necessary to display a screen for checking whether there is an input signal from the sensor and perform the confirmation, or to display a screen for testing whether the device operates normally after removing the cause of the abnormality and perform an operation test of the device.
For this reason, the packaging device of Patent Document 1 has a problem in that the burden of operations and work required for recovery is not reduced for the operator.

In this regard, Patent Document 2 (JP 2001-219906 A) discloses a stretch packaging machine equipped with a controller that monitors whether or not an abnormality has occurred in the device, and if an abnormality has occurred, displays the location and details of the abnormality on the display of a touch panel input device.
In the stretch packaging machine of Patent Document 2, the controller 11 continuously monitors the operating status of the inverters 13, 15 of the table rotation motor 30 and the carriage lifting motor 50, and also continuously monitors the output signals of the limit switches 23, 24 that regulate the upper and lower limits of the lifting and lowering movement of the carriage 4, and the proximity sensor 25 below the turntable 3. If an abnormality is detected in any of these switches, information regarding the location and content of the abnormality is output to the touch panel input device 12 and displayed on the display 12a (paragraph [0032] of Patent Document 2).
Specifically, when there is an abnormality in the output signals from limit switches 23, 24, display screen E2 (carriage descent abnormality screen) or display screen E3 (carriage upper and lower limit sensor abnormality screen) is displayed, and on display screens E2 and E3, a button for selecting "Drawing" or "Photo" is displayed, and by pressing this button, the abnormality is displayed as a drawing or photo on the screen of display 12a, and a button for selecting device monitor is displayed, and by pressing this button, the status of the limit switches is displayed on the screen of display 12a, and by pressing the limit switch on the screen to check its operation, it is possible to check whether or not limit switch 24 is broken (paragraphs [0033] to [0035] of Patent Document 2).
However, in the stretch wrapping machine of Patent Document 2, in order to see a drawing of the abnormal area, it is necessary to press a button such as "Drawing," and in order to check whether there is an abnormality in the limit switch, it is necessary to press a button to select the device monitor, select the limit switch to be checked from the limit switches displayed on the screen, and check its operation.
This poses a problem in that the burden of operations and work required for recovery is not significantly reduced for workers.
Furthermore, in the stretch wrapping machine of Patent Document 2, it is not possible to test whether the device operates normally after removing the cause of the abnormality.

Japanese Patent Application Publication No. 9-2480 JP 2001-219906 A

[Operation of the Vertical Pillow Packaging Machine Control Unit 40 and Operation Panel 50]
Next, we will explain the operation of the vertical pillow packaging machine control unit 40 and the operation panel 50 when the detection signal from the operation detection sensor that detects the operation of the operating part of the vertical pillow packaging machine main body 10 is abnormal, for example, when the detection signal from the proximity sensor 20S is abnormal.
Now, when an operator displays a date position left/right adjustment screen (not shown) on the input display unit 54 of the operation panel 50 and touches a button (switch) to move the date printing device 13a left/right in order to change or adjust the position of the date printing device 13a, if the detection signal from the proximity sensor 20S that detects the operation (rotation) of the motor 20M is abnormal, the abnormality warning signal generating unit 41a of the vertical pillow packaging machine control unit 40 generates an abnormality warning signal, and this abnormality warning signal is transmitted from the transmission/reception unit 43 via the communication line CL to the transmission/reception unit 53 of the operation panel 50, and then sent from the transmission/reception unit 53 to the calculation processing unit of the computer 51.
In the calculation processing section of the computer 51, the abnormality warning screen generating section 51a generates the abnormality warning screens 100A and 100B.
The abnormality warning screen 100A consists of an indication of the type of abnormality warning, a sensor installation image 101 generated by the sensor installation image generation unit 51a1, an input monitor display 103 generated by the input monitor display generation unit 51a3, an output monitor display 104 generated by the output monitor display generation unit 51a4, a test operation button section 105 generated by the test operation button generation unit 51a5, a display image switching button 106, and a confirmation button 108.
In addition, the abnormality warning screen 100B comprises an indication of the type of abnormality warning, a control box image 102 generated by the control box image generation unit 51a2, an input monitor display 103 generated by the input monitor display generation unit 51a3, an output monitor display 104 generated by the output monitor display generation unit 51a4, a test operation button section 105 generated by the test operation button generation unit 51a5, a display image switching button 106, and a confirmation button 108.

An abnormality alarm screen 100A is displayed on the input display section 54 of the operation panel 50. This abnormality alarm screen 100A displays the type of abnormality alarm ("Alarm No. 005" and "Date left/right movement pulse abnormality") and displays a sensor installation image 101, so that the operator can know that the detection signal (pulse signal) from the proximity sensor 20S (sensor AA05) that detects the operation of the date printing device 13a (motor 20) is abnormal, where the date printing device 13a is located, what the structure of the movement mechanism 20 is, and where the proximity sensor 20S (sensor AA05) is installed.
In this case, the worker investigates the cause of the abnormality in the detection signal (pulse signal) from the proximity sensor 20S (sensor AA05) and performs work to eliminate the abnormality.
First, the operator checks whether the indicator lamp 103a on the input monitor display 103 is lit or not. If the indicator lamp 103a is not lit, this indicates that there is an operational abnormality in the proximity sensor 20S (sensor AA05), and if the indicator lamp 103a is lit, this indicates that there is no operational abnormality in the proximity sensor 20S (sensor AA05).
If the indicator lamp 103a is not lit and there is an operational abnormality in the proximity sensor 20S (sensor AA05), the worker performs an operation to eliminate the operational abnormality.
Specifically, the worker touches the display image switching button 106 on the abnormality warning screen 100A to display the abnormality warning screen 100B.
The worker then checks the position of the monitor lamp indicating that a signal is being input from the proximity sensor 20S (sensor AA05) in the control box 60 using the speech bubble image 102b of the control box image 102 displayed on the abnormality warning screen 100B, and checks whether the monitor lamp of the proximity sensor 20S (sensor AA05) in the control box 60 is actually lit. If it is not lit, the worker performs the specified work defined in the manual.
The worker also checks the position of the terminal in the control box 60 to which the lead wire of the proximity sensor 20S (sensor AA05) is connected using the speech bubble image 102d of the control box image 102 displayed on the abnormality warning screen 100B, and actually checks inside the control box 60 to see if the lead wire of the proximity sensor 20S (sensor AA05) has come loose from the terminal, and if the lead wire has come loose from the terminal or the screw has loosened, performs the specified work defined in the manual.

Next, if the indicator lamp 103a of the input monitor display 103 is lit and there is no operational abnormality in the proximity sensor 20S (sensor AA05), the operator touches the test operation button 105a of the test operation button section 105 on the abnormality warning screen 100A to check whether the indicator lamp 104a of the output monitor display 104 is lit, and touches the test operation button 105b to check whether the indicator lamp 104b is lit.
If either or both of the indicator lamps 104a, 104b do not light up, the worker knows that the date printing device 13a is not moving normally in the left-right direction and that there is an abnormality (malfunction) somewhere in the movement mechanism 20 of the date printing device 13a, and performs work to correct the abnormality (malfunction).
Specifically, the worker touches the display image switching button 106 on the abnormality warning screen 100A to display the abnormality warning screen 100B.
The worker then checks the position of the monitor lamp that lights up when the date printing device 13a moves left or right in the control box 60 using the speech bubble image 102c of the control box image 102 displayed on the abnormality warning screen 100B, and checks whether the monitor lamp on the control box 60 is actually lit.If it is not lit, the worker performs the specified work defined in the manual.
In addition, the worker checks the position of the monitor lamp of the control pack of motor 20M (motor of date printing device 13a) in control box 60 using the speech bubble image 102e of the control box image 102 displayed on the abnormality warning screen 100B, actually checks the lighting state of the monitor lamp inside control box 60, and performs the specified work defined in the manual.
Furthermore, the worker checks the position of the terminal in the control box 60 to which the cable of the motor 20M is connected by looking at the speech bubble image 102f of the control box image 102 displayed on the abnormality warning screen 100B, and actually checks inside the control box 60 to see if the cable of the motor 20M has come loose from the terminal, etc., and if the cable has come loose from the terminal or the screws have loosened, performs the specified work defined in the manual.
In this way, after the worker has performed the work to resolve the abnormality in the detection signal (pulse signal) from the proximity sensor 20S (sensor AA05), the worker touches the test operation buttons 105a, 105b of the test operation button section 105 on the abnormality warning screen 100A or abnormality warning screen 100B, and checks whether the indicator lamps 104a and 104b on the output monitor display 104 are lit, that is, a test operation is performed to check whether the date printing device 13a moves normally in the left and right directions, and confirms that the abnormality has actually been resolved and that the position of the date printing device 13a can be changed and adjusted normally.

As described above, in the vertical pillow packaging machine 1, when the detection signal from the proximity sensor 20S that detects the operation of the date printing device 13a (motor 20M) is abnormal, the abnormality warning screen generating unit 51a generates an abnormality warning screen 100A including a sensor installation image 101, an input monitor display 103, and a test operation button unit 105, and an abnormality warning screen 100B including a control box image 102 instead of the sensor installation image 101, based on the abnormality warning signal generated by the abnormality warning signal generating unit 41a. From the sensor installation image 101, the worker can know where the date printing device 13a is located, what kind of structure the movement mechanism 20 has, and where the proximity sensor 20s is installed, and from the control box image 102, the worker can know where the control box The operator can see the position of the monitor lamp indicating that a signal is being input from the proximity sensor 20S within 60, the position of the monitor lamp that lights up when the date printer 13a moves left and right, the position of the terminal to which the lead wire of the proximity sensor 20S is connected, the position of the monitor lamp of the control pack of the motor 20M, and the position of the terminal to which the cable of the motor 20M is connected. Furthermore, the operator can see from the input monitor display 103 whether there is an operational abnormality in the proximity sensor 20S, and from the output monitor display 104 and the test operation button section 105 whether there is an abnormality (fault) somewhere in the movement mechanism 20. After correcting the abnormality, a test operation can be performed to check whether the date printer 13a moves normally left and right.

When an abnormality alarm is issued by signals from various sensors, the packaging-related device of the present invention significantly reduces the burden of operations and work on the operator to eliminate the cause of the abnormality alarm, and allows the test operation of the device to be performed more quickly after the cause of the abnormality alarm is eliminated, significantly shortening the time until recovery, and can be used in vertical pillow packaging machines, horizontal pillow packaging machines, wrapping packaging machines, overwrapping packaging machines, boxing machines, etc.
