Furthermore, the thickness of product B There is no need for the operator to remove the gas from the bag for adjustment, and the burden on the operator can be reduced.
- the packaging system 100 of the present embodiment includes, in addition to the configuration of the vertical bag making and packaging machine 1 (the packaging machine) shown in the first embodiment, a thermostatic chamber 11 (a heat application section). And a seal checker 10 (post-processing unit). Note that FIG. 8 shows only a part of the configuration of the vertical bag making and packaging machine 1 for easy understanding.
- the constant temperature chamber 1 1 applies heat to the product B (package) produced by the vertical bag making and packaging machine 1 to expand the gas (gas) enclosed in the product B, thereby expanding the product B. Inflates.
- the inside of the constant temperature chamber 11 is maintained at a predetermined temperature higher than that of the outside.
- the product B is heated by passing through the inside of the constant temperature chamber 11. Accordingly, the gas sealed in the product B is warmed to the same temperature as the outside air in a short time.
- a hot air shower that applies heat to the product B by blowing hot air onto the product B may be employed.
- the seal checker 10 is a device for checking whether or not the product B manufactured in the vertical bag making and packaging machine 1 has a defective seal.
- a seal motor 10a, a pressing member 10b, and the like are included. Have.
- the servomotor 10a abuts and separates the pressing member 10b from the product B.
- the pressing member 10b presses the product B by making contact with the product B by the servo motor 10a.
- the seal checker 10 detects the bag height of the product B (thickness of the product B) when pressing the product B with the pressing member 10b, and determines whether the seal is defective based on the displacement of the detected value. Make a judgment. Further, the detection information on the bag height of the product B detected by the seal checker 10 is sent to the control unit 7 (see FIG. 9) which controls the vertical bag making and packaging machine 1 and the constant temperature chamber 11. .
- the control unit 7 shown in FIG. 9 controls the cooling unit 6 and the constant temperature chamber 11 based on the detection information in the seal chuck 10. That is, in consideration of the easiness of the check operation in the seal checker 10, the control unit 7 sets the cooling unit 6 based on the detection information in the seal checker 10 so that the bag height of the product B becomes maximum. (Gas temperature change section) To control the gas cooling temperature.
- the cooling unit 6 here has substantially the same configuration as the cooling unit 6 in the first embodiment, but the amount of gas can be automatically adjusted by a drive mechanism such as a motor, and the control unit 7 Can control the amount of gas by controlling the drive mechanism.
- control unit 7 controls the constant temperature chamber 11 based on the detection information in the seal checker 10 in consideration of the easiness of the check operation in the seal checker 10.
- control unit 7 controls the temperature of the hot air blown to the product B based on the detection information in the seal checker 110.
- the control unit 7 may be provided separately for each device and connected by a communication line, or may be an overall control of the individual control unit separately provided for each device and the control unit of each device. It may be configured by a centralized control unit that performs centralized control.
- the vertical bag making and packaging machine 1 produces a product B in which food and the like and a gas having a temperature lower than the outside air are sealed inside the bag.
- the product B separated from the subsequent film F is discharged from the vertical bag making and packaging machine 1 and transported to the constant temperature chamber 11 by the belt conveyor CV.
- the product B transported to the constant temperature chamber 11 is heated while passing through the inside of the constant temperature chamber 11.
- the expansion of the gas sealed in the product B is promoted.
- the gas inside the product B is heated to a temperature close to the outdoor temperature in a short time, and the product B expands to a desired state while passing through the constant temperature chamber 11. In this way, an appropriate product B height can be obtained.
- the product B discharged from the constant temperature chamber 11 is conveyed to the seal checker 10 by the belt conveyor CV.
- the seal checker 10 checks whether the product B has a bad seal by comparing the displacement of the bag height of the product B when the pressing member 10b is pressed with the reference value. Is checked. If the product B is a proper product, the product B is further transported and processed such as packing. In the case of post-processing such as boxing, product B, which has passed through the constant temperature chamber 11 and is already at an appropriate height, can be easily processed. Further, detection information on the bag height of the product B detected by the seal checker 10 is transmitted to the control unit 7 and is fed back to the control in the cooling unit 6 and the constant temperature chamber 11. Thereby, the temperature control in the cooling unit 6 and the constant temperature chamber 11 is performed more appropriately.
- a constant temperature chamber 11 is provided between the vertical bag making and packaging machine 1 and the seal checker 10 and the product ⁇ is a vertical bag making and packaging machine 1 and a sealer: L locker 10 Is warmed while being transported. Therefore, the product can be expanded to a desired bag height in a short time before being conveyed to the seal checker 10.
- the packaging system 100 can easily process the product ⁇ having an appropriate bag height with relatively few errors in the seal checker 100 and other post-processing devices after the bag-making and packaging process. As a result, the operation rate of the production line such as the vertical bag making and packaging machine 1 can be improved.
- the packaging system 100 is provided with the seal checker 10 as a post-processing device for performing post-processing on the product ⁇ , the bag height of the product ⁇ which is inflated by applying heat from the constant temperature chamber 11 is provided. Data can be obtained immediately.
- this packaging system 100 detection information of the seal failure in the seal checker 10 is sent to the control unit 7, and the control unit 7 controls the constant temperature chamber 11 and the cooling unit 6 based on the detection information. Thereby, the constant temperature chamber 11 and the cooling unit 6 can be more appropriately controlled.
- the gas is cooled through the cooling unit 6 before being sent to the former 30.
- a mechanism for cooling the gas path 303 of the former 30 is provided, and the gas is cooled by the gas.
- the gas may be cooled as it passes through path 303.
- the gas is directly cooled by the cooling unit 6;
- the gas may be cooled. That is, by cooling an object in contact with the gas, the temperature of the object may be transmitted to the gas to cool the gas.
- the gas in the bag may be cooled by cooling the food or the like filled in the bag or before or after the film F is formed into a cylindrical shape by the former 30.
- the gas is cooled and then introduced into the cylindrical film Fmc.
- the order of cooling the gas and introducing the gas into the cylindrical film Fmc may be reversed.
- Good That is, first, a gas at normal temperature is introduced into the tubular film F mc, the gas is cooled together with the tubular film F mc, and then the tubular film F mc may be sealed c
- Production of the product B in this order thus, it is possible to produce a product B in which a gas having a temperature different from the outside air is sealed.
- the product B is expanded by cooling the gas.
- the product B can be shrunk by heating the gas.
- the thickness of the product B can be freely increased or decreased by using both the cooling and the warming.
- control unit 7 may control the gas supply unit 5 and the cooling unit 6 so that the gas temperature and the blowing amount can be automatically controlled.
- control unit 7 controls the gas temperature and the blowing amount in consideration of the size of the bag to be manufactured, the size and shape of the food or the like filled in the bag, the outside air temperature, and the like. Control the thickness of B.
