Description

  The present invention relates to a container heat treatment apparatus that heat-treats a container, for example, a container filled with a beverage and sealed.

  When effervescent beverages containing carbon dioxide such as beer or carbonated beverages are filled and sealed in cans, the temperature of the beverage itself is usually set so that the carbon dioxide dissolved in the beverage is difficult to escape. Is kept relatively low. For this reason, the temperature of the can container immediately after the beverage is filled and sealed becomes significantly lower than the dew point, and as a result, the surface of the can container may be condensed. In such a case, it is difficult to attach a label to the can container and to print on the can container.

  Furthermore, when packing a plurality of can containers with a packaging body or packing can containers into a cardboard box, the packaging body or the cardboard box may be wetted by the surface of the condensed can container. If the package or cardboard box is wet, the package or cardboard box may be deformed or damaged during transportation.

Therefore, as disclosed in Patent Document 1, it has been conventionally performed to supply hot water to a sealed can container by a container heat treatment apparatus, thereby preventing condensation on the surface of the can container. is doing. Furthermore, Patent Document 2 discloses that a high-frequency induction heating method is employed in order to eliminate heating unevenness when heat treating a can container.

Embodiments of the present invention will be described below with reference to the accompanying drawings. In the following drawings, the same members are denoted by the same reference numerals. In order to facilitate understanding, the scales of these drawings are appropriately changed.
FIG. 1 (a) is a schematic diagram of a beverage container packaging apparatus including a container heat treatment apparatus according to the first embodiment of the present invention. In FIG. 1 (a), a beverage container packaging device 10 includes a filling machine 11 for filling and sealing a container C, for example, a can container (not shown in FIG. 1 (a)), and a sealed container. And a warmer 12 (container heat treatment apparatus) for heating the container C. The warmer 12 serves to prevent dew condensation from occurring on the surface of the container C by spraying warm water into the container C after sealing. In addition, the warmer 12 may serve as the role which performs retort sterilization.

  Furthermore, the beverage container packaging device 10 includes a printing device 13 that prints the date of manufacture on the container C, and a labeler 14 that attaches a label (in this case, a campaign seal) to the surface of the container C. In the beverage container packaging device 10 shown in FIG. 1A, the labeler 14 is not necessarily required, and the labeler 14 may be omitted. Furthermore, the beverage container packaging apparatus 10 includes a multipack packaging apparatus 15 that forms a multipack package by surrounding a plurality of containers C with a packaging material, and a caser 16 that packs the plurality of multipack packages in a cardboard box. It is out. In addition, as shown in the figure, the container C and the multipack package are conveyed in the direction of the arrow by a conveying device 19, for example, a conveyor, and reach the storage warehouse 17.

  Moreover, FIG.1 (b) is the schematic of the other drink container packaging apparatus containing the container heat processing apparatus based on 1st embodiment of this invention. In FIG.1 (b), drink container packaging apparatus 10 'packages bottle containers, such as a glass bottle filled with the drink. This beverage container packaging device 10 'includes a filling machine 11 and a warmer 12 that can also serve as a pastoriser. Further, a bottle inspection machine 13 ′, a labeler 14 for attaching a product label to a container, and a caser 16 for packing a plurality of containers in a cardboard box are disposed downstream of the warmer 12 in the transport direction of the transport device 19. .

  These beverage container packaging devices 10, 10 'may be used to package plastic bottles such as plastic bottles containing beverages.

  In the beverage container packaging device 10 shown in FIG. 1A, it is assumed that there is a maximum dew point between the warmer 12 and the printing device 13. In FIG. 1A, a dew point meter 39 is provided in the transport device 19 so that the maximum value of the dew point between the warmer 12 and the printing device 13 can be measured. Furthermore, in the beverage container packaging apparatus 10 ′ shown in FIG. 1B, it is assumed that there is a maximum dew point between the warmer / pass riser 12 and the bottle inspection machine 13 ′. Also in the beverage container packaging apparatus 10 ′ shown in FIG. 1B, the dew point meter 39 ′ can measure the maximum dew point between the warmer / pass riser 12 and the bottle inspection machine 13 ′. Is provided. It is assumed that each of the dew point meters 39 and 39 'shown in FIGS. 1A and 1B is electrically connected to a control device 30 described later.

  These dew point meters are, for example, dew point meters that directly measure the dew point, such as a mirror-cooled dew point meter, for example, by measuring the humidity and temperature using a capacitive humidity sensor. The dew point meter which calculates a dew point from the value of may be sufficient. Although not shown in the drawings, each of these dew point meters is preferably covered with a filter or the like. Thereby, it becomes possible to reduce the influence of the disturbance on the measured value of the dew point meter. That is, for example, if the worker passes only around the dew point meter, the measured value of the dew point meter hardly fluctuates. Therefore, in the present invention, a stable dew point can be obtained.

  FIG. 2 is a detailed view of a warmer in the beverage container packaging apparatus. As shown in FIG. 2, a plurality of containers C are sequentially passed through the warmer 12 by the transfer device 19. The warmer 12 sprinkles hot water from the nozzle 27 into the container C. The hot water is temporarily stored in the hot water receiving unit 28, and is supplied again to the nozzle 27 through the pipe line 25 by driving the pump 43. The nozzle 27 shown in FIG. 2 is provided only above the container C. However, in order to uniformly heat the container C, it is desirable to provide the nozzle 27 on the side or below the container.

  FIG. 3 is a partial perspective view of the warmer. As shown in FIG. 3, the guide portions 49 may be arranged on both sides of the transport device 19 in the warmer 12. By the guide portions 49, the plurality of containers C are generally aligned when transported on the transport device 19 as shown in the figure. Accordingly, the warm water from the nozzle 27 is evenly sprinkled into each of the plurality of containers C. Therefore, the plurality of containers C are evenly heated when the containers C described later are heated, and the variation in heating between the containers C can be reduced.

  Referring back to FIG. 2, the pipe line 25 passes through the heat exchanger 23 together with the other pipe line 22. When the on-off valve 41 provided in the pipe line 22 is opened, hot water from the high-temperature water tank 21 is supplied to the heat exchanger 23 through the pipe line 22. Next, the hot water from the high temperature water tank 21 is recovered in the low temperature water tank 24 by applying heat to the hot water in the pipe 25 in the heat exchanger 23.

  Further, a steam source 26 is connected to the hot water receiving unit 28 through a pipe line 29. When required, the on-off valve 42 of the pipe line 29 is opened to supply the steam in the steam source 26 to the hot water in the hot water receiving unit 28. Thereby, the warm water in the warm water receiving part 28 can be further heated. The steam source 26 is not necessarily required, and the hot water in the hot water receiving unit 28 may be heated only by the heat exchanger 23 and related equipment.

  A control device 30 shown in FIG. 2 controls the operation of the warmer 12. The control device 30 is a digital computer, a required temperature determining means 31 for determining a required temperature required for the beverage in the container C, a temperature adjusting means 32 for adjusting the temperature of the beverage in the container C, and various parameters (described later). And a storage unit 33 in which a map to be stored in advance is stored.

  Further, as can be seen from FIG. 2, the temperature adjusting means 32 controls the rotation speed of the motor 44 connected to the conveying device 19 to adjust the conveying speed of the conveying device 19, and the opening / closing valve 41. , 42 for controlling the temperature of the hot water sprayed from the nozzle 27 by controlling the opening of the nozzle 42, and the flow rate of the hot water sprayed from the nozzle 27 by controlling the rotational speed of the pump 43 in the conduit 25. It serves as the hot water flow rate adjusting means 37 for adjusting the temperature.

  When beverages are filled and sealed in the filling machine 11, the containers C are sequentially transported to the warmer 12 by the transport device 19. In the warmer 12, the warm water from the nozzle 27 is sprinkled into the container C, whereby the container C is heated. In the embodiment shown in FIG. 2, the temperature of the hot water sprayed from the nozzle 27 is determined as follows based on the dew point Td between the warmer 12 and the printing device 13 measured by the dew point meter 39.

  First, the dew point Td is supplied to the required temperature determining means 31 of the control device 30. In the required temperature determining means 31, the required temperature Tr of the beverage in the container C passing through the warmer 12 is determined as Tr> Td. Next, the hot water temperature adjusting means 36 of the temperature adjusting means 32 determines the temperature Tw of the hot water based on the following formula (1) so as to satisfy Tr> Td.

      Tw = Td + a + b (1)

  Here, the constant a is a value indicating how much the temperature of the beverage in the container C rises when hot water is sprinkled from the nozzle 27 into the container C.

  FIG. 4A shows a map of the constant a. As shown in FIG. 4A, the constant a is stored in the storage unit 33 of the control device 30 in the form of a map as a function of the type of beverage and the type of container C. It is assumed that such a map is obtained in advance by experiments or the like. In addition, as a kind of drink in a container, tea drink, coffee, etc. are mentioned in addition to carbonated drinks, such as beer and Chuhai. Moreover, as a kind of container C, in addition to container materials, such as a can container, a PET bottle, and a glass bottle, the dimension of a container, for example, a regular can, a long can, etc. shall be mentioned.

  The constant b is a margin for variations in measured values of the dew point meter and variations in control equipment. As in the case of the constant a, the constant b is also stored in the storage unit 33.

  When the temperature Tw of the hot water is calculated based on the constants a and b, the hot water temperature adjusting means 36 changes the opening degree of the on-off valves 41 and 42 according to the temperature Tw of the hot water. Thereby, the temperature of the hot water sprayed from the nozzle 27 is adjusted to become the temperature Tw. As a result, the temperature of the beverage in the container C becomes higher than the dew point Td as the hot water having the temperature Tw is sprinkled. Therefore, while suppressing the formation of condensation on the surface of the container C while minimizing the energy required to spray the hot water and heating the container C, the deterioration of the beverage flavor is prevented. Is possible.

  Depending on the location where the beverage container packaging device 10, 10 ′ is arranged in a factory building, the portion of the beverage container packaging device 10, 10 ′ where the dew point is maximized may be different. Even in such a case, in the present invention, it is sufficient to adjust the water temperature based on the maximum dew point Td (max) in the beverage container packaging device 10, 10 '. Thereby, it is possible to prevent the surface of the container C from condensing regardless of the installation location of the beverage container packaging device 10, 10 '.

  In particular, an object of the present invention is to prevent dew condensation in the printing device 13 and / or the storage warehouse 17 or the like located downstream of the warmer 12. Therefore, it is desirable to obtain the maximum dew point downstream of the warmer 12. FIG. 5 (a) and FIG. 5 (b) are schematic views of beverage container packaging devices 10, 10 'according to the second embodiment of the present invention, respectively. As shown in FIG. 5A, a plurality of dew point meters 39 a to 39 j are sequentially provided along the transport device 19. As can be seen from FIG. 5A, the dew point meters 39b, 39d, 39f, 39h, and 39j are provided in the transport device 19 in the printing device 13, the labeler 14, the multipack packaging device 15, the caser 16, and the storage warehouse 17, respectively. ing. Other dew point meters 39a, 39c, 39e, 39g, and 39i are provided in the transport device 19 outside these devices.

  Also in the beverage container packaging device 10 ′ shown in FIG. 5B, a plurality of dew point meters 39 a, 39 b ′, 39 c to 39 e, 39 h, 39 i, 39 j are sequentially provided along the transport device 19. As can be seen from FIG. 5 (b), the dew point meters 39 b ′, 39 d, 39 h and 39 j are provided in the transport device 19 in the bottle inspection machine 13 ′, the labeler 14, the caser 16 and the storage warehouse 17, respectively. Other dew point meters 39a, 39c, 39e, and 39i are provided in the transfer device 19 outside these devices. Each of the dew point meters shown in FIG. 5A and FIG. 5B is also connected to the control device 30 in the same manner.

  In such a case, first, a plurality of dew points Td are measured by each of a plurality of dew point meters 39a to 39j provided along the transport device 19. Next, the temperature Tw of the hot water is adjusted as described above based on the maximum dew point Td (max) among these dew points Td. Even in this case, it is possible to reliably prevent the surface of the container C from condensing in all steps after the heat treatment step by the warmer 12. That is, since the condensation of the container C conveyed to the printing device 13 or the like is prevented, the printing operation by the printing device 13 and the label sticking by the labeler 14 can be favorably performed, and the packaging in the multipack packaging device 15 is possible. It is also possible to avoid getting the cardboard boxes in the body and caser 16 wet.

  By the way, when a certain dew point meter of a plurality of dew point meters measures a very high dew point due to a failure or the like and the temperature Tw of the hot water is controlled based on the dew point, it is necessary to heat the container C. There is a possibility that the energy that is generated becomes extremely large and the container C cannot be heated properly. In order to cope with such a situation, it is preferable to set an allowable range related to the dew point in advance.

  By the way, there is a possibility that an extremely high dew point Td is measured when an operator passes near the dew point meters 39a to 39j or when the lid of the box in which the dew point meters are arranged is opened. In this case, the energy required to heat the container C becomes extremely large. Alternatively, a very low dew point Td may be measured for other reasons, for example due to a dew point meter failure. When the container C is heated based on the extremely low dew point Td, dew condensation may occur on the surface of the container C even after heating.

  For this reason, predetermined upper and lower limit values regarding the dew point Td are determined in advance, and when the measured dew point Td deviates from the range between these upper limit value and lower limit value, the dew point Td is not taken into consideration. Is desirable. Thereby, it is possible to prevent the container C from being heated more than necessary even when a very high dew point Td is measured, and the container C is condensed even if a very low dew point Td is measured. Can be prevented.

  In FIG. 2, a blower 45 that blows dry gas onto the container C is provided downstream of the nozzle 27. The blower 45 plays a role of blowing off small droplets of hot water adhering to the surface of the heated container C. Thereby, it can prevent that the container to which the water droplet adhered after heating is conveyed with the water droplet adhered. In addition, it is preferable that the temperature of the dry gas supplied from the blower 45 is comparatively high temperature so that the container C may not be cooled and dew condensation may occur.

  By the way, in other embodiment, the present conveyance speed V0 of the conveying apparatus 19 is reduced to the conveyance speed V lower than this using the conveyance speed adjustment means 35. FIG. FIG. 6 is a diagram showing a map of the conveyance speed V. As shown in FIG. 6, the conveyance speed V is stored in the storage unit 33 in the form of a map as a function of the type of beverage, the type of container C, and the dew point Td. These transport speeds V are obtained in advance by experiments or the like so that the required temperature Tr of the beverage in the container C satisfies Tr> Td.

  In this case, the transport speed adjusting means 35 determines the transport speed V according to the type of beverage, the type of container C, and the dew point Td. Then, the conveyance speed adjusting means 35 changes the rotation speed of the motor 44 and reduces the current conveyance speed V0 of the conveyance device 19 to the conveyance speed V. Thereby, the time when the warm water from the nozzle 27 is sprinkled in one container C becomes longer, and the container C can be further heated. Therefore, it is possible to prevent condensation on the surface of the container C without changing the temperature Tw of the hot water and without heating the container C more than necessary.

  In still another embodiment, the current flow rate F0 of the hot water from the nozzle 27 is reduced to the flow rate F by the hot water flow rate adjusting means 37. FIG. 7 is a diagram showing a map of the hot water flow rate F. As shown in FIG. As in the case of the conveyance speed V, the hot water flow rate F is also stored in the storage unit 33 in the form of a map as a function of the beverage type, the container C type, and the dew point Td.

  In this case, the hot water flow rate adjusting means 37 determines the hot water flow rate F corresponding to the type of beverage, the type of container C, and the dew point Td. Then, the hot water flow rate adjusting means 37 changes the rotation speed of the pump 43 to reduce the current flow rate F0 of the hot water from the nozzle 27 to the flow rate F. Also in this case, the flow rate of the hot water sprayed into one container C increases, and the container C can be further heated. Accordingly, even in this case, it is possible to prevent condensation on the surface of the container C without changing the temperature Tw of the hot water and without heating the container C more than necessary.

  Furthermore, it is within the scope of the present invention to appropriately combine some of these embodiments. That is, at least two of the transport speed adjusting means 35, the hot water temperature adjusting means 36, and the hot water flow rate adjusting means 37 may be used simultaneously.

  Alternatively, the temperature Tc of the heated container C may be measured by the non-contact type thermometer 48 (see FIG. 2), and the temperature Tw of the hot water may be automatically corrected based on the measured temperature Tc. . It is also possible to monitor whether or not there is an abnormality in the beverage in the container C based on the temperature Tc of the container C measured by the non-contact type thermometer 48. That is, when the temperature Tc of the container C is extremely high, an abnormality may occur in the beverage in the container C. Therefore, the container C having such a temperature Tc may be excluded. It will be appreciated that this ensures the quality of the beverage in the container C.
