<Operation of Encapsulation Sealing Device 5>
Next, operation | movement of the enclosure sealing apparatus 5 of the enclosure sealing system 1 which is one Embodiment of this invention is demonstrated.

  FIG. 6 is a flowchart showing a processing procedure of the enclosing / sealing apparatus 5 of the enclosing / sealing system 1 according to the embodiment of the present invention.

  As illustrated in FIG. 6, the device control unit 411 of the enclosing / sealing controller 401 acquires the temperature T in the device casing 41 measured by the thermometer 320 (step S101).

  Next, the device control unit 411 determines whether or not the temperature T acquired in step S101 is equal to or lower than the set temperature TTH (step S103). Here, the set temperature TTH is set in advance as a temperature at which, for example, 15 (° C.) or the like, the water paste applied to the adhesive coating unit 123 is difficult to activate and the adhesion failure of the envelope paper P2 is likely to occur. ing.

  When it is determined in step S103 that the temperature T is equal to or lower than the set temperature TTH (in the case of YES), the device control unit 411 determines whether or not the water application position has been reached (step S105). Specifically, the device control unit 411 determines that the water application position has been reached when the paper sensor 208 detects that the conveyed envelope paper P2 has hit the abutting member 93. At this time, when the envelope paper P <b> 2 is folded in half by the envelope forming unit 85, the heating region 124 that is in a position facing the adhesive coating unit 123 reaches the vicinity of the heater 306.

  If it is determined in step S105 that the water application position has been reached (in the case of YES), the device control unit 411 turns on the heater 306 (step S107). Thereby, the heating area | region 124 used as the position which opposes the adhesive agent coating part 123 when it is folded in half is heated by the heater 306.

  And the apparatus control part 411 will turn off the heater 306, if application | coating of the water to the adhesive agent coating part 123 of the envelope paper P2 by the hydration mechanism 99 is complete | finished (step S109: YES) (step S109). S111).

  FIG. 7 is an explanatory diagram for explaining the operation of the enclosing / sealing device 5 of the enclosing / sealing system 1 according to an embodiment of the present invention. (A) is the figure which showed the state in which it was detected that the envelope paper P2 conveyed had hit | abutted against the abutting member 93, (b), after application | coating of the water by the hydration mechanism 99 was complete | finished, FIG. 5C shows a state where the envelope paper P2 is conveyed, and FIG. 5C shows a state where the envelope paper P2 is folded and conveyed.

  As shown in FIG. 7A, when it is determined that the conveyed envelope paper P2 has reached the water application position, the heating unit 78 is turned on, and when the envelope sheet P2 is folded in half, the adhesive coating unit 123 The heating region 124 that is the opposite position is heated by the heating unit 78. In this way, the warming region 78 is heated by the warming unit 78, and then the warming region 124 comes into contact with the adhesive coating unit 123, so that the water application mechanism 99 applies the adhesive. The temperature of the water applied to the construction part 123 rises. Thereby, water becomes easy to permeate the adhesive application part 123, and the water paste applied to the adhesive application part 123 is easily activated.

  Next, as shown in FIG. 7B, when the application of water by the hydration mechanism 99 is completed, the heating by the heating unit 78 is turned off. The final folding roller 95 folds the envelope paper P2 from the folding line P2b in cooperation with the main folding roller 87 in a state where the vicinity of the folding line P2b of the envelope paper P2 is slackened.

  Then, as shown in FIG. 7C, the folded envelope paper P <b> 2 is in contact with the heating area 124, which is a position facing the adhesive application part 123, and the adhesive application part 123. Be transported.

  As described above, according to the encapsulating and sealing apparatus 5 of the encapsulating and sealing system 1 according to the embodiment of the present invention, the heating unit 78 can apply the adhesive when the envelope sheet P2 is folded in half by the envelope forming unit 85. Since the heating region 124 that is positioned to face the portion 123 is arranged to be heated, the heating region 124 that is positioned to face the adhesive coating portion 123 and the adhesive coating portion 123 are By making it contact, the temperature of the water applied to the adhesive application part 123 by the hydration mechanism 99 is raised. This makes it easy for water to permeate the adhesive application part 123, facilitates activation of the water paste applied to the adhesive application part 123, and can reliably seal the envelope paper P2.

  Here, for example, in order to easily activate the water paste applied to the adhesive application unit 123, it is conceivable to preheat the water 222 stored in the water storage container 221. However, when the water 222 is preliminarily heated, dew condensation caused by evaporated water vapor may adversely affect the driving equipment in the machine.

The impact of equipment degradation due to is small.

  It is also conceivable that after the envelope paper P2 is folded in half by the envelope forming portion 85, the adhesive coating portion 123 coated with water by the hydration mechanism 99 is heated. However, in this case, since a considerable amount of time is required after the water is applied by the hydration mechanism 99, the water applied to the adhesive coating unit 123 drips down without penetrating and is applied to the adhesive coating unit 123. It becomes difficult to activate the water paste.

  On the other hand, according to the enclosed sealing device 5 of the enclosed sealing system 1 which is an embodiment of the present invention, the warming unit 78 has the adhesive coating unit 123 when the envelope paper P2 is folded in two by the envelope forming unit 85. Is disposed so as to heat the heating region 124, the water is applied to the adhesive coating unit 123 by the hydration mechanism 99, and the water is heated before the applied water drips down. Since the area | region 124 and the adhesive agent coating part 123 contact, the water paste applied to the adhesive agent coating part 123 will be activated.

  As described above, according to the encapsulating and sealing apparatus 5 of the enclosing and sealing system 1 according to the embodiment of the present invention, the heating unit 78 can apply the adhesive when the envelope paper P2 is folded in half by the envelope forming unit 85. Since it arrange | positions so that the heating area | region 124 used as the position which opposes the process part 123 may be heated, envelope paper P2 can be sealed reliably.

  In the sealed sealing system 1 according to the embodiment of the present invention, when the paper sensor 208 detects that the conveyed envelope paper P2 hits the abutting member 93, the water application position is reached. Although it determined, it is not restricted to this.

  For example, the paper sensor 208 detects the envelope paper P <b> 2 conveyed before hitting the abutting member 93, and turns on the heater 306 at a timing when the envelope paper P <b> 2 hits the abutting member 93. Also good.

  That is, a sensor for detecting the conveyance of the envelope paper P2 is provided, and on / off of the heater 306 may be controlled based on the position of the envelope paper P2 detected by the sensor.
