  The cooling unit 43 is provided with a pair of upper and lower cooling plates facing each other with the heat-resistant belts 33a and 33b interposed therebetween. A plurality of through holes are formed in the upper and lower cooling plates 43a and 43b, and cool air is blown from a blower provided inside the housing 8 to be cooled. Curing is promoted by the seal portion passing between the cooled upper and lower cooling plates 43a and 43b. The upper heating plate 41a and the upper cooling plate 43a are pressed against opposing lower members that are urged and fixed in the vertical direction Z by a mounting mechanism (not shown).

  As shown in FIGS. 1 to 3, the second transport mechanism 50 is generally disposed between the upper and lower front V belt pulleys 51 a and 51 b and the upper and lower rear V belt pulleys 52 a and 52 b that are coaxial with the previous upper and lower rear pulleys 32 b and 32 b. The upper and lower V belts 53a and 53b are stretched over. The upper and lower V-belts 53 a and 53 b sandwich and sandwich the packaging bag 100 that has passed through the heating and cooling unit 40, and send it to the printing device 6 described later via the pressing unit 55.

  The upper and lower rear V-belt pulleys 52a and 52b are slidably attached through the long holes 54a of the attachment plate 54 located on the downstream side D from the printing device 6. As a result, the tensions of the upper and lower V-belts 53a and 53b are adjusted and maintained.

  The pressing portion 55 includes a load cell that presses the bag mouth portion 101 of the heated and cooled packaging bag 100 to give a pattern to the heat seal portion and measures the sealing pressure on the packaging bag 100. As shown in FIG. 1, a sensor 56 that detects the packaging bag 100 conveyed to the printing device 6 is provided on the downstream side D of the pressing portion 55.

  As shown in FIG. 4, the sensor 56 is attached to an attachment plate 60 to which each member of the printing apparatus 6 described later is attached via an attachment member 56a. In the vicinity of the sensor 56, guide plates 57a and 57b are provided to face each other with an interval in the vertical direction Z. The guide plates 57 a and 57 b guide the movement of the bag mouth portion 101 to the printing device 6.

Next, the printer 6 according to the first embodiment of the present invention will be described with reference to FIGS.
The printing device 6 generally includes an attachment plate 60 for attaching each member to be described later, a print head 70 that performs printing on the transported packaging bag 100, and a pressing member that presses a portion of the transported packaging bag 100 against the receiving base 64. 80. The printing device 6 is provided on the downstream side D in the transport direction X from the heating / cooling unit 40 via the mounting plate 60, and the expiration date, date of manufacture, NET, and the like in the packaging bag 100 in which the bag mouth portion 101 is heat-sealed. Print characters (symbols, etc.) such as lot numbers.

  As shown in FIGS. 2 and 5, the mounting plate 60 is fixed to a slide plate 91 slidable with respect to a receiving member 92 provided in the housing 8. The slide plate 91 and the receiving portion 92 serve as a print position adjustment mechanism 90 that adjusts the print position with respect to the packaging bag 100. Thereby, the printing device 6 can be slid in the horizontal direction Y substantially orthogonal to the conveyance direction X of the packaging bag 100 via the mounting plate 60, and the printing position can be adjusted.

  As shown in FIG. 2, the printing apparatus 6 in the present embodiment generally includes a hot stamping foil tape 61 as a printing tape, an unwinding reel 62, a take-up reel 63, and a foil tape 61. A stamp head 70A serving as a print head 70 that presses the print head 70; a cradle 64 provided facing the stamp head 70A; and a pressing device 65 that presses the stamp head 70A in the vertical direction Z. Thus, the printing apparatus 6 in the first embodiment constitutes a hot stamp apparatus (foil pressing apparatus) as schematically shown in FIG.

  As shown in FIGS. 2, 4, and 5, the foil tape 61 is supplied between the stamp head 70 </ b> A and the cradle 64 via a plurality of guide rollers 68 from the take-up reel 62 and is taken up by the take-up reel 63. . The take-up reel 63 is rotationally driven by the drive of the reel driving device 67 to take up the foil tape 61. The pressing device 65 moves up and down by, for example, a crank mechanism. A fixing plate 66 for fixing a later-described stamp head 70A and pressing member 80 is provided on one end side thereof. Further, the tape tape 61 is prevented from slackening during supply by the tension holding mechanism 69.

  The supply direction of the foil tape 61 is a direction Y substantially orthogonal to the conveyance direction X of the packaging bag 100. On the other hand, the packaging bag 100 is also transported between the stamp head 70 </ b> A and the cradle 64 by the second transport device 50. Then, in a state where the foil tape 61 and the packaging bag 100 are overlapped, the stamp device 70A is pressed by the pressing device 65 against the receiving base 64 to perform printing. The pedestal 64 is provided with a rubber base 64a having elasticity.

  As shown in FIGS. 6 and 7, the stamp head 70 </ b> A generally includes a plurality of type 71, a type holder 72 that holds the type 71, and a hot platen 73 that appropriately heats the type 71. The type 71 is arranged in the recess 72a of the type holder 72, and is fixed to the type holder 72 by fixing means 74 including a screw 74a and a clamping member 74b. The type holder 72 can be attached to and detached from the heating plate 73 by sliding it with a handle 76. As shown in FIG. 7, a pressing member 80 that presses the packaging bag 100 conveyed together with the stamp head 70 </ b> A against the receiving base 64 is attached to the fixed plate 66. The type 71 moves up and down in the vertical direction Z from the stamp head 70A by electric or pneumatic pressure.

  As shown in FIGS. 4 to 7, the pressing member 80 has, for example, a plate-like substantially square shape, and is attached to the fixed plate 66 via a substantially U-shaped arm 81, a connecting member 82, and a support member 83. . This pressing member 80 is located on the upstream side U in the transport direction X with respect to the previous stamp head 70A.

  The support member 83 includes a first support member 83a provided with an elastic member such as a spring, and a second support member 83b. The second support member 83b is not provided with an elastic member. These members are slidable with respect to the through holes of the arm 81 and the connecting member 82. Thereby, the pressing member 80 moves up and down along the vertical direction Z, and presses the conveyed packaging bag 100 against the receiving table 64.

Here, with reference to FIG. 9, the printing process for the conveyed packaging bag 100 will be described in detail.
The packaging bag 100 heat-sealed by the heating / cooling unit 40 is sandwiched between the upper and lower V-belts 53 a and 53 b of the second transport mechanism 50 and transported toward the printing device 6. Then, it is detected by the sensor 56 before being conveyed between the cradle 64 and the stamp head 70A. Drive of the pressing mechanism 65 and the reel driving mechanism 67 is started by the detection signal of the sensor 56. The vicinity of the bag mouth portion 101 of the packaging bag 100 is guided between the upper and lower guide plates 57a and 57b and is conveyed between the cradle 64 and the stamp head 70A.

  The pressing mechanism 65 lowers the stamp head 70 </ b> A and the pressing member 80 in the vertical direction Z via the fixed plate 66. Then, as shown in FIG. 9A, before the foil tape 61 is pressed by the stamp head 70A, the pressing member 80 first presses a part of the bag mouth portion 101 of the packaging bag 100 against the receiving base 64. Here, as shown in FIG. 6B, the packaging bag 100 is sandwiched between the upper and lower V-belts 53a and 53b in the vicinity of the bag mouth portion 101. Therefore, the periphery of the printing area P facing the stamp head 70A is held by the pressing member 80 and the upper and lower V-belts 53a and 53b, and the movement in the transport direction X is forcibly stopped. The pressing member 80 is located on the upstream side U in the transport direction X with respect to the stamp head 70A. Therefore, wrinkles are unlikely to occur around the print area P on the bag mouth portion 101, and printing can be performed clearly.

  Then, as shown in FIG. 3C, the type 71 of the stamp head 70A presses the foil tape 61 against the bag mouth portion 101 in a state where the periphery of the printing area P is held, and printing is performed. As a result, misalignment of printing is prevented. Then, as shown in FIG. 4D, the stamp head 70A is first separated from the foil tape 61, and then the pressing of the pressing member 80 is released. Thereby, generation | occurrence | production of the printing whisker which arises when the type 71 separates from the foil tape 61 can be suppressed, and it can be set as clearer printing. The character string C printed on the bag mouth portion 101 is along the transport direction X (tape width direction).

  Moreover, in the series of steps described above, the conveyor belt 12 and the upper and lower V-belts 53a and 53b are driven without stopping. As shown in FIG. 9B, the pressing member 80 is located on the upstream side U in the transport direction X with respect to the stamp head 70A. Further, the time during which the pressing member 80 presses the bag mouth portion 101 against the receiving base 64 is a short time during which the foil tape 61 is pressed against the printing area A by the stamp head 70A. For this reason, even if the upper and lower V-belts 53a and 53b are driven, the influence on printing is small.

  Further, as shown in FIG. 9B, since the bag mouth portion 101 is forcibly stopped by the pressing member 80, the main body portion 102 is distorted in the transport direction X due to inertia. However, the pressing time is a short time and does not affect the quality of the packaging bag 100. Therefore, complicated drive control for the conveyor unit 3 of the heat sealing apparatus 1 and the first and second transport mechanisms 30 and 50 is not required. In addition, since there is no need to stop the conveyor unit 3 and the first and second transport mechanisms 30 and 50, printing can be performed efficiently.

  Next, a second embodiment of the present invention will be described with reference to FIGS. In the following embodiments, the same reference numerals are given to the same members as those in the above-described embodiments. In the first embodiment, the printing device 6 constitutes a hot stamp device (foil stamping device). However, the printing device 6 in the second embodiment constitutes a so-called thermal printer.

  By the way, in the intermittent thermal printer 6 ′ as shown in FIG. 11A, printing is performed by stopping the conveyed printing medium 100 ′ and moving the thermal head 70 </ b> B ′ in the vertical and horizontal directions. Therefore, when used as the printing device 6 'in the heat sealing device, the transport mechanism for transporting the packaging bag 100 must be stopped each time printing is performed, and complicated control is required. In addition, workability becomes inefficient.

  Further, in the continuous thermal printer 6 ″ as shown in FIG. 11B, the supply direction Y ′ of the thermal ribbon 61 ′ and the continuous movement direction P ′ of the printing medium 100 ′ are set in the same direction. The thermal head 70B ″ moves up and down in the vertical direction Z with respect to that direction. Therefore, as shown in FIG. 11C, the thermal ribbon 61 ′ must be supplied by the length L of the character string C ′ to be printed, which increases the consumption of the thermal ribbon 61 ′ and increases the cost. Become.

  As shown in FIG. 10 (a), the printing apparatus 6 according to the second embodiment generally includes a winding reel 62 and a take-up reel 63 for supplying a thermal ribbon 61 as a printing tape, and a thermal ribbon 61 in a packaging bag. A thermal head 70B serving as a print head 70 that presses and prints on the print head 100 and a pedestal 64 that faces the thermal head 70B are provided. The thermal head 70B can be moved in the horizontal and vertical directions by a moving mechanism. Is attached.

  Also in the thermal printer 6 of the present embodiment, the supply direction Y of the thermal ribbon 61 as a printing tape is substantially orthogonal to the transport direction X of the packaging bag 100. On the other hand, the moving direction of the thermal head 70B is the same as the transport direction X. Moreover, the pressing member 80 is provided in the upstream U of the conveyance direction X of the packaging bag 100 with respect to the thermal head 70B similarly to the said embodiment.

  The pressing member 80 presses a part of the packaging bag 100 against the receiving table 64 to forcibly stop the movement of the packaging bag 100. Next, the thermal head 70 </ b> B descends in the vertical direction Z and moves in the transport direction X to press the thermal ribbon 61 against the packaging bag 100. Accordingly, as shown in FIG. 10B, the direction of the character string C printed on the packaging bag 100 is along the width direction (conveying direction X) of the thermal ribbon 61. Therefore, the consumption of the thermal ribbon 61 can be suppressed and it is economical.

  As in the first embodiment, the packaging bag 100 is sandwiched and transported between the upper and lower V-belts 53a and 53b. Thereby, it is not necessary to stop the 1st, 2nd conveyance mechanisms 30 and 50 of the heat seal apparatus 1, and complicated control is also unnecessary. And since it can print in the stop state, it becomes clear printing.

Finally, reference is made to the possibilities of yet another embodiment of the invention.
In the first and second embodiments, a hot stamp and a thermal printer are used as the printing device 6. However, the present invention is not limited to these printing apparatuses.

  Moreover, in each said embodiment, it clamped with the upper and lower V belts 53a and 53b of the 2nd conveying apparatus 50 which conveys the packaging bag 100, and conveyed it to the printing apparatus 6. FIG. However, the upper and lower V-belts 53a and 53b may be omitted and only the conveyance by the conveyor belt 12 may be performed. However, each of the above-described embodiments for printing in the state of nipping and conveying by the upper and lower V-belts 53a and 53b is superior in that printing is performed clearly while preventing misalignment or the like.

  Moreover, in each said embodiment, the pressing member 80 was formed in plate-shaped substantially square shape. However, the shape of the pressing member 80 is not particularly limited. For example, as shown in FIGS. 12A and 12B, an L shape or a U shape may be used so as to surround the periphery of the print region P. However, these shapes enable the bag mouth portion 101 to be pressed in the vicinity of the print region P, but they must be provided so as not to contact the print tape 61 or the print head, and the structure becomes complicated. In this respect, the above embodiment is excellent.

  Further, in each of the above embodiments, the pressing member 80 is provided on the upstream side U in the conveyance direction X of the packaging bag 100 with respect to the print head 70. However, the installation position of the pressing member 80 is not limited to the upstream U in the transport direction X. For example, you may provide in the downstream D of the conveyance direction X with the pressing member 80 like the 2nd pressing member 80A shown with a dashed-dotted line in FIG.12 (b).

In such a case, the second pressing member 80A may be provided integrally with the pressing member 80, or may be provided independently. However, since the second pressing member 80 </ b> A is located on the downstream side D of the print head 70, it is necessary not to prevent the pressing effect on the pressing member 80. For example, pressing is started simultaneously with the pressing member 80, and pressing is released simultaneously with the pressing member 80. The pressing may be started after the pressing member 80 and the pressing may be released before the pressing member 80. As described above, it is necessary to adjust the timing of pressing so as not to hinder the suppression of the occurrence of printing misalignment, whiskers, bleeding, and the like by the pressing member 80, which complicates the structure and requires control. In this respect, the above embodiment is excellent.

  Furthermore, in each said embodiment, the pressing member 80 was supported by the 1st support member 83a provided with the elastic member, and the 2nd support member 83b which is not providing the elastic member. However, the support mode of the pressing member 80 is not limited thereto, and for example, a pair of first support members 83a including an elastic member may be provided as shown in FIG. Further, as shown in FIG. 4D, a cushioning material 85 such as rubber may be provided on the pressing member 80 instead of the elastic member, or the pressing member 80 itself may be constituted by the cushioning material. However, the above embodiment is excellent in that the transported packaging bag 100 can be reliably pressed against the cradle 64.

  INDUSTRIAL APPLICABILITY The present invention can be used as a printing apparatus and a printing method for a printing medium such as a packaging bag in which various products such as food, pharmaceuticals, daily necessities, and industrial products are stored.
