  Next, a preferred embodiment of the seal temperature control apparatus in the bag making and filling machine according to the present invention will be described below with reference to the accompanying drawings.

  As shown in FIG. 1, a horizontal bag making and filling machine (hereinafter referred to as a packaging machine) according to an embodiment forms a strip-like film 14 containing an aluminum material drawn from a supply source 12 into a cylindrical shape by bag making means 16. Then, articles W are supplied into the tubular film 14 from the supply conveyor 18 at predetermined intervals, and the film 14 is transported, and a desired seal is applied by the sealing bodies 24 and 30 constituting the sealing means. To get to. The packaging machine has a pair of film conveying means for conveying the film 14 by a driving means such as a servo motor 23 while sandwiching the overlapping end portion 14a extending in the conveying direction of the film 14 formed into a cylindrical shape by the bag making means 16. The feed rollers 22 and 22 and the film 14 that is disposed on the downstream side of the feed rollers 22 and 22 and protrudes downward from between the transport beds 20 and 20 on which the film 14 supplied with the article W is placed. And sealing bodies 24 and 24 constituting a pair of vertical sealing means for sandwiching and sealing the overlapping end portion 14a.

  The seal body 24 shown in FIG. 1 and FIG. 2 is connected to the machine frame 10 via the arm 25 so that the upper portion of the seal body 24 can abut against or separate from the overlapping end portion 14a of the film 14. It is supported so that it can rotate horizontally. Each sealing body 24 is heated by a heater (heating means) 26, and an upper roller is rotationally driven by a driving means such as a servo motor (not shown) to seal the film 14 while sandwiching the overlapping end portion 14a. In the upper roller, temperature detecting means 28 comprising a temperature sensitive element such as a thermocouple for detecting the temperature of the seal body 24 is disposed. The temperature detection signal from the temperature detection means 28 is configured to be input to the temperature adjustment means 38. Then, the packaging machine uses temperature control means by a feedback control method such as PID control so that each seal body 24 is within an appropriate seal temperature having an upper and lower width sandwiching the target seal temperature set in advance by the setting means 40. The heating temperature of the heater 26 is adjusted based on the temperature detected by the temperature control unit 38 based on the temperature detected by the temperature control unit 38, and an appropriate vertical seal (also referred to as a center seal) is applied to the overlapping end portion 14 a of the film 14 by the pair of seal bodies 24, 24. ) Is given.

  As shown in FIG. 1, the packaging machine is disposed on the downstream side of the seal body 24 in the film conveyance direction, and constitutes a seal body 30 that constitutes a pair of lateral seal means that are vertically opposed to each other across a horizontal film feeding path. , 30. The pair of seal bodies 30, 30 is configured to move the article W placed in the tubular film 14 by performing a predetermined rotation operation so as to be in phase with the conveyance of the film 14 by a driving means such as a servomotor (not shown). A lateral seal (also referred to as an end seal) is applied to the film 14 before and after being sandwiched, and the film 14 is cut by a cutter 32 disposed on the seal body 30. Each seal body 30 incorporates a heater 34 as a heating means capable of adjusting the temperature. In addition, each seal body 30 is provided with a temperature detection means 36 composed of a thermosensitive element such as a thermocouple for detecting the temperature in the vicinity of the seal surface sandwiching the film 14. The detection result is input to the temperature adjusting means 38. The seal body 30 is detected by the temperature detection means 36 by a feedback control method such as PID control so that the seal body 30 is within an appropriate seal temperature having an upper and lower width sandwiching the target seal temperature preset by the setting means 40. Based on the measured temperature, the heating temperature of the heater 34 is adjusted under the control of the temperature adjusting means 38.

  The setting means 40 is used to control the control unit 42 that performs overall management of the control unit 42 that performs sealing and transporting of the film 14 and the temperature control unit 38, and the like, such as a target seal temperature, product information, and packaging processing speed. It is configured to be able to set data related to specifications, and various specific settings can be made by inputting various information on various setting screens (not shown) displayed on the touch panel, so In association with each other, information such as the target seal temperature and the packaging processing speed of each seal body 24 and each seal body 30 is stored. Furthermore, the setting means 40 performs display switching of setting screens such as a temperature correction operation mode setting screen shown in FIG. 3 and a screen (selection screen: not shown) for selecting whether to use the temperature correction operation mode. Each piece of information is input to the screen and stored in the control means 42 in association with each type of packaging. When the temperature of the seal bodies 24, 30 is low, such as after the packaging machine is turned on, the corresponding heaters 26, 34 are turned on so that the temperature of the seal bodies 24, 30 is, for example, the target seal. After the temperature rises to a predetermined temperature near the target seal temperature and stabilizes, the above-described temperature control by the temperature adjusting means 38 is performed. In addition, when the front and back of the cylindrical film 14 are made of different materials, the target seal temperatures for the paired seal bodies 24, 24 or 30, 30 can be set differently.

  Both the sealing bodies 24 and 30 are driven and controlled by the control means 42 so as to synchronize with the supply of the film 14 and the article W based on the data related to the packaging specification inputted through the setting means 40, and the temperature. By adjusting the heating temperature of the heaters 26 and 34 by the adjusting means 38, the surface temperature of each of the seal bodies 24 and 30 is managed. Note that the packaging machine is also provided with an operation start switch and an operation stop switch (both not shown) for starting or stopping the drive control and the like. , The operation stop signal) is input to the control means 42, and the operation start signal, the operation stop signal, etc. are supplied to the temperature adjusting means 38, or the temperature detection signal input to the temperature adjusting means 38 is supplied to the control means 42. For example, various data are exchanged between the control means 42 and the temperature adjustment means 38. When an operation stop signal is generated by operating the operation stop switch or detecting an abnormality during operation, the packaging machine stops all or part of the operation of the packaging machine, and the pair of seal bodies 24, 24 are opened substantially simultaneously with the operation stop. The film 14 is separated from the polymerization end portion 14a of the film 14 to prevent the film 14 from being seized. The pair of seal bodies 30 and 30 are also stopped in a state of being separated from the film 14 when the operation is stopped. When the operation start signal is generated by operating the operation start switch, the packaging machine starts or restarts the operation of the packaging machine, and the seal body 24 is attached to the polymerization end of the film 14 at approximately the same time or at a predetermined timing. It abuts on the portion 14a, and the abutment state is maintained throughout the operation. In addition, in order to stabilize the temperature of each sealing body 24 and 30 at the time of the operation start of a packaging machine, and a stop of operation, in this packaging machine, packaging by the temperature correction operation mode is possible in the following procedures. .

Here, an operation procedure for applying a temperature correction operation mode for stabilizing the temperature of the seal body 24 will be described. First, data relating to packaging specifications such as information on products to be packaged and target seal temperatures of the respective seal bodies 24 and 30 are set in the control means 42 via the setting means 40, and then set in the setting means 40 as shown in FIG. In order to display the screen and select the seal bodies 24 and 30 to be applied in the temperature correction operation mode from the registered seal bodies (indicated as center sealer, end sealer, and sealer in FIG. 3), of the four types of selection keys title registered being displayed (selecting means), a touching selection keys Sentashira front HT01 and Sentashira inner room HT02 corresponding to the pair of sealing members 24, 24, teaching the start of the screen Touch the key to confirm. The setting means 4 0, such as the corresponding Packaging to register another seal member (sealer of FIG. 3 HT05~HT12), are enabled select these different seal body.

When it is confirmed on the temperature display screen that the temperature of the heater 26 of each seal body 24 has risen and stabilized, and an operation start switch (not shown) is operated, the feed roller 22, the seal bodies 24, 30, etc. Is started, and a notification indicating that sampling is incomplete, such as “sampling in progress” or “teaching in progress”, is started on the screen of the setting means 40. This display is continuously performed until a temperature control signal described later is generated. At this time, based on the operation start signal, the control means 42 instructs the temperature adjustment means 38 to sample the temperature of each seal body 24, and sampling of each temperature is started. In this example, the temperature is sampled at the start of operation by the temperature adjustment means 38, from the generation of the operation start signal, the temperature value detected by the temperature detection means 28 is the appropriate seal temperature corresponding to the target seal temperature. It is executed until it is determined that the temperature is stable for a predetermined time within the range, and the temperature value sampled during that time is sequentially stored as data in the temperature adjusting means 38. That is, the completion of the sampling is due to the fact that when the sealing bodies 24, 24 sandwich the film 14 at the start of operation, the film 14 takes heat greatly exceeding the heating amount to the sealing body 24 so far. This is a period from when the temperature of the seal body 24 greatly decreases beyond the range of the proper seal temperature until the temperature adjusting means 38 completes the recovery of the seal body 24 to the proper seal temperature.

  When the temperature value detected by the temperature detection means 28 is continuously stabilized within the range of the proper seal temperature and the temperature sampling is finished, the temperature adjustment means 38 analyzes the sampled temperature data, and the next and subsequent times. A temperature control signal (temperature control value) is generated for setting the temperature of the seal body 24 at the start of operation within a range of an appropriate seal temperature corresponding to the target seal temperature. The temperature control signal is a value of a heating temperature higher than the heating temperature in the sampling period by the heater 26 so as to compensate for the insufficient heat quantity by calculating the insufficient heat quantity from the deviation between the temperature obtained by sampling and the target seal temperature. Are generated in time series corresponding to a period in which the temperature is stable from the start of operation.

  When the generation of the temperature control signal is completed, the temperature control signal is stored in the temperature adjusting means 38, and the screen of the setting means 40 displays “sampling completed at the start of operation” or “teaching completed at the start of operation”. At the start of operation, a message indicating that sampling has been completed and a message prompting you to stop the operation are displayed, such as “Please press the operation stop switch”.

When an operation stop switch (not shown) is operated by an operator who has confirmed the display for prompting operation stop, the control means 42 instructs the temperature adjusting means 38 to sample the temperature of each seal body 24 based on the operation stop signal. The sampling of each temperature is started again, and a notification indicating that sampling is not completed, such as “Sampling is in progress” or “Teaching is in progress” is displayed on the screen of the setting means 40 again. Start. As with the sampling at the start of operation, the temperature sampling at the time of the operation stop is performed by the temperature adjusting unit 38, and the temperature value detected by the temperature detection unit 28 from the generation of the operation stop signal is the appropriate seal corresponding to the target seal temperature. The process is executed until it is determined that the temperature is stable for a predetermined time within the temperature range, and the temperature value sampled during that time is sequentially stored as data in the temperature adjusting means 38. That is, the completion of the sampling is due to the fact that when the seal body 24 is separated from the film 14 due to the operation stop, the heat amount in anticipation of heat being taken away by the film 14 remains in the seal body 24. This is a period from when the temperature of the body 24 greatly exceeds the range of the proper seal temperature and until the temperature adjusting means 38 completes the recovery of the seal body 24 to the proper seal temperature.

When the temperature value detected by the temperature detecting means 28 is continuously stabilized within the range of the proper seal temperature and the sampling of the temperature is finished, the sampled temperature data is analyzed by the temperature degree adjusting means 38 and the next and subsequent times. A temperature control signal (temperature control value) is generated for setting the temperature of the seal body 24 at the time of the operation stop to be within the range of the appropriate seal temperature corresponding to the target seal temperature. The temperature control signal is a temperature lower than the heating temperature in the sampling period by the heater 26 so as to calculate the amount of heat supplied excessively from the deviation between the temperature obtained by sampling and the target seal temperature, and to reduce the amount of heat excessively. Is generated in a time series corresponding to a period in which the temperature is stable after the operation is stopped . When the generation of the temperature control signal is completed, the temperature control signal is stored in the temperature adjustment means 38, and the screen of the setting means 40 displays, for example, “sampling complete at operation stop” or “teaching completed at operation stop”. Displays the completion of sampling when the operation is stopped.

When the operation is resumed after the above sampling is completed, the seal body 24 is heated by the heater 26 so as to be within the range of the proper seal temperature based on the generated temperature control signal at the start of the operation, When the operation is stopped, processing in the temperature correction operation mode in which the seal body 24 is heated by the heater 26 so as to be within the range of the appropriate seal temperature based on the temperature control value by the generated temperature control signal at the time of the operation stop. Will continue. The display screen of the setting means 40 displays a continuation selection key (selection means) for switching and setting whether or not to apply the temperature correction operation mode for each of the various seal bodies 24 and 30, and is not applied. selecting keys, so that the temperature of the seal member 24 is in the proper sealing temperature in a temperature control signal before moving to a temperature correction operation mode, the sealing member 24 is heated by the heater 26.

  FIG. 4 is a diagram showing the temperature change of the seal body 24 corresponding to the selection key of the center sealer front HT01, and the curve (a) shows the temperature change of the seal body 24 when the temperature correction operation mode is not applied. Curve (b) shows the temperature change of the seal body 24 when the temperature correction operation mode is applied. The curve (a) shows that it takes several minutes immediately after the operation start signal is generated (i) until it deviates downward from the range of the proper seal temperature and the temperature continues to stabilize within the proper seal temperature. It takes several minutes in the same way until the temperature deviates upward from the range of the appropriate seal temperature immediately after the occurrence point (b) and the temperature continues to stabilize within the appropriate seal temperature. Curve (b) shows that the temperature drops immediately after the operation start signal is generated (a) and the temperature is increased immediately after the operation stop signal (b) is generated. It is kept within the seal temperature.

Thus, in the temperature correction operation mode, triggered by the generation of the operation start signal or the operation stop signal, the seal bodies 24 and 30 are heated by the temperature control value by the generated temperature control signal. The amount of heat applied to the film 14 by the seal bodies 24, 30 in relation to the heating operation by the seal bodies 24, 30 accompanying the operation of the film conveying means such as the feed rollers 22, 22 during operation and at the time of restart after operation stop. Will not be outside the proper seal temperature range, and the film 14 can be heated stably. In particular, advance to generate a temperature control signal corresponding to the temperature change conditions previously obtained by the sampling, the sealing member 24, 30 surface, such as when the seal member 24 and 30 is thermally in contact with the film 14 is deprived When the temperature changes, the temperature of the seal bodies 24 and 30 can be maintained within the proper seal temperature range without delaying the temperature adjustment timing in accordance with the temperature change time. Then, since the temperature of the seal bodies 24 and 30 is heated so as to approach the target seal temperature using the control temperature value based on the temperature control signal after the operation start and operation stop timings, which cannot be predicted when, It is not necessary to keep the temperature of the sealing bodies 24, 30 inside higher than the target sealing temperature, power consumption can be saved, and seizure of the film 14 due to high heat at the start of operation can be prevented. it can. Further, the temperature compensation operation mode, by setting for each packaging varieties, when the packaging varieties is changed, depending on various packaging conditions such as the material of the film 14 to be used, corresponding to each packaging varieties The temperature control signal generated in this way can be switched and automatically applied. For example, the seal temperature setting and the seal temperature adjustment of the seal bodies 24 and 30 corresponding to the operation status are automatically performed for each package type by the setting means 40 such as a touch panel. The skill level is not required, and can be switched and set by an extremely simple operation.

Further, since the temperature control signal corrected to each of the heaters 26, 34 provided in the pair of sealing members 24, 24 or 30, 30 disposed on both sides of the film 14 so as to apply a higher Accurate seal temperature control can be performed, and the seal state can be further stabilized. By notifying that the sampling by the temperature detection means 28, 36 is incomplete, for example, by displaying a display such as “sampling in progress” on the setting means 40 or the like, the operator finishes the sampling. It can be determined whether or not. Before or after sampling, whether or not to apply the temperature correction operation mode can be switched for the plurality of seal bodies 24 and 30 disposed in the packaging machine, so that a plurality of seals provided in the packaging machine can be set. Depending on the structure of the bodies 24 and 30 and the difference in other sealing conditions, fine temperature control can be set, and a better seal can be achieved.

(Example of change)
The present invention is not limited to the configuration of the examples, and various embodiments can be adopted within the scope of the gist of the present invention. For example, the following modifications can be made.
(1) As the vertical sealing means, as in the sealing means disclosed in Japanese Patent Publication No. 8-11576, heated air is supplied to the polymerization end portion from a position away from the polymerization end portion of the cylindrical film during operation. The film may be transported in a state in which the sealant is melted by spraying continuously, and the polymerization end may be sealed downstream by pressing the polymerization end with a roller or the like. In this case, when the heated air is started to be blown at the start of operation or when the heated air is stopped to be blown when the operation is stopped, the flow amount of the cooled air flowing through the seal body fluctuates, so that it deviates from the proper seal temperature. However, if the temperature control signal is generated in the temperature correction operation mode, the temperature of the seal body can be maintained within the appropriate seal temperature range.
(2) In the temperature correction operation mode, before sampling the temperature of the seal bodies 24 and 30 at the start of operation, the operator automatically confirms that the heater temperature has risen without checking on the setting means screen or the like. Alternatively, sampling may be performed by determining the rising stability of the heater temperature.
(3) In addition to the horizontal form-fill machine, it can be applied to a bag-making filling machine with different sealing means, such as vertical bag filling machine and a three-way sealing device.
(4) In the horizontal sealing means, the temperature of the sealing body 30 obtained by sampling the timing at which the sealing body 30 clamps the film 14 based on pulses from an encoder attached to a servo motor that drives the sealing body 30 is obtained. It is possible to store in association with the value and to generate a temperature control signal based on the stored temperature value.
(5) The temperature detecting means 28, 36 may be disposed on the surface of the seal bodies 24, 30, or may be a non-contact type.
(6) The input function in the setting means may be configured by a switch such as a button or dial.
(7) A situation such as incomplete sampling may be notified by screen display, sound or voice.
