Description

The present invention relates to a vertical bag-making filling and packaging machine, and more particularly to a vertical bag-making filling and packaging machine suitable for attaching a card or a sticker of a pouch containing a card.

Conventionally, a small bag containing a trading card or the like or a single card (hereinafter, a single card and a small bag containing a card are collectively referred to as a "card-like article"" in a bag product packed with snacks or the like as a bonus of the product. ) Is pasted and sold. Bag products to which such a pouch containing a card is attached have been manufactured by combining a normal vertical bag-making filling and packaging machine (hereinafter, also referred to as “packaging machine”) with a card affixing machine.

Here, the wrapping machine is provided with a cylinder-making unit that forms a wrapping material unwound from a raw roll into a tubular shape, a vertical sealing device that vertically seals the wrapping material formed into a tubular shape, and a vertical seal. It is configured to be equipped with a horizontal sealing device that horizontally seals and cuts a tubular packaging material in which the product is dropped from above.

On the other hand, the card sticking machine has a card stocker that stocks card-shaped articles, a sticker sticking device that sticks a double-sided sticker to the card-shaped articles supplied from the card stocker, and the pouch to which the double-sided sticker is stuck. It is configured to include an arm to be attached to the tubular packaging material and a drive mechanism thereof on the side of the vertical sealing device of the packaging machine.

Patent Document 1 discloses an example of a technique for manufacturing a bag product with a card-shaped article by a configuration in which such a packaging machine and a card sticking machine are combined.

On the other hand, with regard to the latest packaging machine, in order to improve productivity, the packaging material is sent at a speed higher than that of the packaging machine disclosed in Patent Document 1, and the horizontal sealing device is driven at a high speed in synchronization with this. It is designed.

Further, the latest packaging machine has been subjected to various improvements to the above-mentioned basic configuration so as to suppress the production of defective products accompanied by defective sealing and improve the productivity.
For example, in such a packaging machine, products dropped from above the packaging machine are stacked inside the tubular packaging body, and when horizontal sealing is performed in this state, the products are caught between the horizontal sealers, resulting in poor sealing. In order to prevent the product from being woken up, a horizontal sealing device having a product biting prevention function by "squeezing operation" and a packaging machine equipped with the horizontal sealing device have also been developed.

In addition to the pair of lateral sealers, such a lateral sealing device is provided with a shutter plate and an ironing plate at the upper and lower portions thereof, respectively. In such a configuration, just before the pair of horizontal sealers sandwiching the packaging material is closed, the ironing plate first sandwiches the packaging material and closes, and in this state, the ironing plate is moved from top to bottom together with the pair of horizontal sealers. It is designed to be moved and squeezed. After that, the lateral sealer is closed and the sealing operation is performed.

Patent Document 2 discloses a packaging machine provided with a horizontal sealing device having such a product biting prevention function.

Special Publication No. 63-000293 Japanese Unexamined Patent Publication No. 10-297619

With the high production capacity shown by the packaging machine disclosed in Patent Document 2, there may be a potential demand in the industry for attaching a card-shaped article to a bag product.
However, even if the packaging machine of Patent Document 2 described above is simply combined with the sticking machine disclosed in Patent Document 1, for example, a sticking arm of the sticking machine and a horizontal sealing device capable of moving up and down along with an ironing operation are provided. Because they are placed in close proximity to each other, some structures may interfere with each other, and as a result, it is not possible to simply install the affixing machine on the packaging machine, and as a result. There is a disadvantage that the card cannot be attached by a wrapping machine having high productivity.

In addition, compared to the technology of Patent Document 1 such as the packaging machine of Patent Document 2, the new packaging machine conveys the packaging material at a higher speed and also performs the horizontal sealing operation at a higher speed in order to realize high productivity. Therefore, the conventional card sticking machine may not be able to cope with this speed, or even if it is supported, problems such as poor card sticking may occur. Further, by transporting the packaging material at high speed, the influence of the air on the attached card-shaped article becomes large, and the position of attachment becomes more important. From this point of view, there is still room for further technical improvement.

There is. However, when the card-shaped article Cd is carried in from the first position P1 to the second position P2, and when it is pushed out from the third position to the fourth position, it interferes with the movement of the card-shaped article Cd. A part of the structure on the upper front side of the right guide member 66 and the guide rail 66A, and a part of the structure on the lower back side of the guide rails 65A and 66A have been removed.

At the third position P3, a card sticking device 70 for extruding and sticking the card-shaped article Cd shown in FIGS. 2 to 2 toward the packaging material sticking position (that is, the fourth position P4) of the packaging machine 10 is arranged. There is.
The card sticking device 70 includes a movable upper piston rod 71 and a lower piston rod 72 having suction portions 71A and 72A for sucking card-shaped articles Cd at the tip, and the upper and lower piston rods 71 and 72. A rod holding block 73 for holding and supporting, a holding block moving mechanism 74 for moving the rod holding block 73 forward or backward in the direction shown by the arrow B in FIG. 1, and a holding block driving device 75 for driving the rod holding block 73. And have.
Here, the upper piston rod 71 and the lower piston rod 72, and the suction portions 71A and 72A have a ventilation path formed inside so that the card-shaped article Cd can be sucked by suction, and the compressor (not shown) has a ventilation path. Communicating.

Of these, the upper piston rod 71 and the lower piston rod 72 are arranged vertically side by side in parallel as shown in FIGS. 2 and 3. In FIG. 5, the upper piston rod 71 and the lower piston rod 72 are located side by side directly above or directly below each other, although they are hidden by the suction transfer arm 56 and cannot be seen.
Further, the distance between the upper piston rod 71 and the lower piston rod 72, that is, the distance between the suction portions 71A and 72A may be any distance, but it substantially corresponds to the upper nozzle 61 and the lower nozzle 62 of the adhesive injection device 60. It is preferable to set the interval.
In this way, the adhesive applied to the back surface of the card-shaped article Cd can effectively adhere to the position where the tubular packaging material Ft is attached, and further, the adhesion can be completed by using a small amount of adhesive, which is economical. Is also excellent.

The left guide member 65, the right guide member 66, and the card sticking device 70 are arranged on a horizontal table 76 (see FIGS. 2 to 5), and the horizontal table 76 is provided via another structure. It is fixed to the sticker main body frame 41.

Further, in the present embodiment, as will be described later with reference to FIG. 8, a central region extending in the vertical direction of the card-shaped article Cd is bonded within a vertically long preferable adhesiveable range indicated by a diagonal line in the drawing. The configuration is suitable for. As a result, even if the card-shaped article is attached at a corresponding speed while the vertical seal partial packaging material that enters parallel to the horizontal sealer 31 is conveyed at a high speed, the card-shaped article Cd due to improper attachment or contact with the horizontal seal device 30. Drops can be reduced and productivity can be improved.

(Aisle for attaching cards)
As described above, in the present embodiment, the upper and lower piston rods 71 and 72 of the card sticking device 70 are brought into contact with the card sticking position (P4) of the tubular packaging material Ft on the outer peripheral surface of the filling cylinder 15. It is composed.
In other words, the packaging machine 10 according to the present embodiment has the central point of the card sticking region, which is the region where the card-shaped article Cd contacts on the filling cylinder 15 or the tubular packaging material Ft, in the space region in the normal direction. It is provided that the card-shaped article Cd to be affixed has a card affixing passage area capable of passing in a posture substantially parallel to the card affixing area when moving toward the card affixing area. It is a feature. In other words, the wrapping machine 10 is laid out so that a part of the structure such as the back-pasting device 23 and the adhesive injection device 60 does not enter the passage.

Since the card-shaped article Cd is provided with such a card sticking passage area, the card-shaped article Cd can be stuck by simply moving it linearly toward the sticking area of the tubular packaging material Ft, and the path required for sticking is shortened. It also supports the pasting operation so that it can be speeded up. Further, since the card-shaped article Cd is more firmly pressed against the packaging material Ft because it is attached by pressing it linearly in this way, more reliable attachment is possible and the occurrence of improper attachment is reduced.

(Control device)
As shown in FIG. 1, the packaging machine 10 of the present embodiment determines the operation of each component of the packaging machine 10 (for example, the packaging material feeding device 17, the vertical sealing device 20, the horizontal sealing device 30, and the like) and their timings. A control unit 80 for controlling is provided.
Further, in the present embodiment, the control unit 80 is electrically connected to a controller (not shown) of the card sticking machine 40, and by communicating with the controller (not shown), each component of the card sticking machine 40 (not shown). For example, the operation of the belt drive device 54 of the card stocker 50, the drive device of the card transfer device main body 57, the adhesive injection device 60, and the card sticking device 70 and their timings are also controlled, and the packaging machine and the sticking machine described later are also controlled. To realize the collaborative operation of.
An input unit (not shown) for giving instructions by the operator and a display unit (not shown) for showing operating parameters of the device are also connected to the control unit 80.

(Squeezing operation and sealing operation)
Next, with reference to FIG. 7A, the ironing operation and the sealing operation of the lateral sealers 31, 31, the shutter mechanism 32, and the ironing mechanism 33 will be described.
Here, in the present embodiment, it is assumed that the tubular packaging material Ft is stopped during the ironing operation, the lateral sealing operation, and the cutting operation.

First, at point A, the lateral sealers 31 and 31 are at the highest points within the operating range in the elevating (vertical) direction. At this time, a tubular packaging material Ft (not shown) has passed between the horizontal sealers 31 and 31 (gap), in other words, the horizontal sealers 21 and 21 have the tubular packaging material Ft and the tubular packaging material Ft being conveyed. It is opened to a position where it does not interfere with the card-shaped article attached to it.

Next, the lateral sealers 31 and 31 approach each other while slightly descending from the point A and head toward the point B. At this point B, the shutter plates 32C and 32C provided above the horizontal sealers 31 and 31 are brought into contact with each other via the flat tubular packaging material Ft. Further, the ironing plates 33C and 33C provided above the horizontal sealers 31 and 31 are also brought into mutual contact with each other via the flat tubular packaging material Ft, and the gap between the horizontal sealers 31 and 31 is closed.

Next, the lateral sealers 31 and 31 descend from the point B to the point C by a distance a (the section of this distance a is also referred to as a "squeezing section"). Therefore, even when the product P is stacked in the area to be horizontally sealed in the tubular packaging material Ft, the ironing plates 33C and 33C descend while sandwiching the tubular packaging material Ft, so that they are stacked and sealed. The ironing plates 33C and 33C can move the product P, which may be an obstacle in performing the above, downward to eliminate the product P. (That is, a "squeeze action" is performed).

Therefore, it is possible to prevent the horizontal sealers 31 and 31 from biting the product P at the time of horizontal sealing, and it is possible to reduce the need for urgent maintenance such as stopping the packaging machine 10 when biting occurs. This can be done, and the production of defective packages can be reduced, so that the production efficiency is improved.

The lateral sealers 31 and 31 end the ironing operation at the point C. On the other hand, the lateral sealers 31, 31 further approach each other toward each other. At this time, the shutter plate 32C and the ironing plate 33C are already in contact with each other, but as described above, the spring contracts and the shutter plate 32C and the ironing plate 33C are projected due to the spring urging. Can be pushed in so as not to prevent the lateral sealers 31 and 31 from approaching each other.

Next, the heated sealing surfaces are brought into contact with each other, and heat sealing is performed for a certain period of time on the planned horizontal sealing portion of the tubular packaging material Ft. When the heat seal is performed for a certain period of time, the horizontal seal device 30 activates a cutter device (not shown) to cut the tubular packaging material Ft.
Next, when the lateral sealers 31 and 31 are separated from each other and then the ironing plates 33C and 33C are separated from each other, the cut bag product falls.
Finally, the lateral sheilas 31 and 31 pass through points F and G and return to the first point A.

(About the sticking position of card-shaped articles)
Next, with reference to FIG. 8, the tubular packaging material Ft in a flat state is shown, and at which position of the tubular packaging material Ft it is preferable to attach the card-shaped article Cd will be described.
FIG. 8 shows an outline of the flat tubular packaging material Ft. The strip-shaped packaging material Ft shown in the drawing has a tip at the lower end in the drawing, and the portion to be cut is tubular at a portion facing upstream by a length L corresponding to the length of the bag. It is shown by a solid line that crosses the packaging material Ft. The portion to be cut further upstream by the length L is indicated by the alternate long and short dash line.
Although the vertical sealing device 20 is not shown in FIG. 8, the tubular packaging material Ft shown is located downstream of the lower end of the vertical sealer 21 of the vertical sealing device 20. .. Therefore, it is premised that the card-shaped article Cd is attached in the area below (downstream) the lower end of the vertical sealer 21.

Further, the range of the distance a + h ₁ above the cut portion and the planned cutting portion and _{the range of the distance h 2} below the cut portion and the planned cutting portion are indicated by diagonal lines, and the boundary thereof is defined as a diagonal line. It is indicated by a two-dot chain line. These ranges are the ranges in which the lateral sealers 31, 31, the shutter mechanism 32, and the ironing mechanism 33 are moved, as is clear from FIGS. 7 (A) to 7 (C). Therefore, if an attempt is made to attach a card within this range, structural interference will occur and the card cannot be attached.
On the contrary, the other range on the tubular packaging material Ft is a range that does not interfere with the pair of lateral sealers 31 and 31 that perform the ironing operation, and the upper and lower shutter mechanisms 32 and the ironing mechanism 33 (in the present specification). This non-interfering range may be simply referred to as "a range that does not interfere with the pair of horizontal sealers 31, 31" or "a range that does not interfere with a part that moves together with the horizontal sealer").

Further, in the explanatory view showing the flat tubular packaging material Ft in FIG. 8, the vertical seal portion Fs is shown by a solid line in the central region of the packaging material along the transport direction. The vertical seal portion Fs is folded down by the guide member 24 of the back-pasting device 23 in the vertical central region of the tubular packaging material Ft of FIG. 8 with respect to the outer surface of the packaging material in this region.
The vertical line indicating the vertical seal portion Fs is indicated by a thick line Fs'on the right side and a thin line Fs' on the left side. The thick line Fs'on the right side indicates the overlapped edge of the tubular packaging material Ft. The thin line Fs'' on the left side indicates the boundary between the tubular body of the tubular packaging material Ft of the vertical seal portion Fs and the vertical seal portion Fs (which can also be said to be the base of the vertical seal portion Fs).

In the figure, the guide plate 24 of the back-pasting device 23 is present on the card-shaped article Cd shown at the most upstream. Basically, the card sticking must be performed on the downstream side of the guide plate 24. On the other hand, by sticking on the downstream side of the guide plate 24 in this way, the sticker can be stuck to the horizontal seal portion Fs firmly tilted by the guide plate 24, so that the card can be stuck reliably and sticking. It is possible to prevent defects and improve productivity.

The lines Fs'and Fs'' described above are also shown in FIGS. 6 (A) and 6 (B).
FIG. 6A shows, as an example, the filling position of the filling cylinder 15, the tubular packaging material Ft wrapped around the filling cylinder 15, the folded vertical seal portion Fs, and the attached card (card-shaped article) Cd. The cross section is shown. FIG. 6B shows, as an example, a filling cylinder 15, a tubular packaging material Ft wrapped around the filling cylinder 15, a folded vertical seal portion Fs, and affixed. The cross section of the card (card-shaped article) Cd is shown.

As seen in FIG. 6A, the card-shaped article Cd is attached so as to be in contact with the vertical seal portion Fs in a substantially central region of the card-shaped article Cd. When adhered to the vertical seal portion Fs in the central region of the card-shaped article Cd, as shown in FIG. 6 (B), when passing between the horizontal sealers 31 and 31, with respect to the seal surface of the horizontal sealer. Card-shaped articles will pass in parallel.

Since this configuration is used, the edge of the card-shaped article Cd that is not adhered even when transported at a high speed is compared with the case where the side edge region of the card-shaped article Cd is attached to the vertical seal portion Fs. Is unlikely to sway during transportation. Further, as compared with the case where the central region of the card-shaped article Cd is adhered at a position away from the base portion Fs'' of the vertical sealing portion Fs, the card-shaped article Cd is parallel to the sealing surfaces of the horizontal sealers 31 and 31. It becomes easier to pass.

Therefore, when the tubular package Ft with the card-shaped article Cd passes between the lateral sealers 31 and 31, the card-shaped article Cd enters the sealing surfaces of the lateral sealers 31 and 31 at an angle not parallel to the result. It is possible to prevent the card-shaped article Cd from coming into contact with the lateral sealers 31 and 31 and peeling off. Therefore, it is possible to improve the production efficiency of the bag product to which the card-shaped article is attached.

Further, since the card-shaped article Cd easily passes parallel to the sealing surfaces of the horizontal sealers 31 and 31, when the tubular package Ft with the card-shaped article Cd passes between the horizontal sealers 31 and 31. In addition, it is not necessary to take a large distance between the horizontal sealers 31 and 31 as compared with other sticking positions. Therefore, the moving distance of the horizontal sealers 31 and 31 can be reduced in the box motion, and the packaging speed can be increased. It will be easier to plan.

Although FIGS. 6 (A) and 6 (B) show an example in which the card is directly attached, the same effect can be expected when the pouch containing the card is attached.
Further, in FIGS. 6 (A) and 6 (B), the vertical seal portion Fs is drawn so as to have a large thickness when the vertical seal portion Fs is folded down. This is for explanation purposes, and in reality, the thickness of the tubular packaging material Ft does not have to be considered so much.

Therefore, when the card-shaped article Cd is attached, it may be adhered not only to the folded vertical seal portion Fs but also to the region on the opposite side with the base portion Fs ″ interposed therebetween. This is shown as the shaded area in FIG. This is a preferable adhesive range.

This preferred adhesive range will be described in more detail.
The preferable adhesive range is different from the card sticking area where the card-shaped article is stuck by the card sticking device, and indicates the range on the tubular packaging material Ft suitable for adhering to the card-shaped article Cd. There is.
The upper and lower ends of this preferable adhesive range are arranged so as not to include the movable range of the horizontal sealers 31, 31 which are a part of the structure of the horizontal sealing device 30, and the shutter plate 32C and the ironing plate 33C associated therewith. ..

Therefore, as is clear from the relationship between the distance and the dimensions shown in FIGS. 8 (B) and 8 (C), the lower end (downstream end) of the preferable adhesive range is "squeezed distance a + lateral sealer" rather than the cutting position. It is located upstream _{by the distance h 1} ”from the center to the upper surface of the shutter plate. Further, the upper end (upstream end) of the preferable adhesive range is located _{downstream from the cutting position by "distance h 2} from the center of the lateral sealer to the lower surface of the ironing plate".

Further, the shaded portion in FIG. 8 is shown as an elongated range extending in the transport direction with the base portion Fs'' of the back-pasted portion or the vertical seal portion Fs shown in FIG. 6 as the center of line symmetry. It is preferable that the vertically extending central region of the card-shaped article Cd is adhered to all or part of such an elongated range (or all or part of the portion along the base Fs'').
For example, according to the present embodiment, the adhesive is applied to two points in the vertically extending central region of the card-shaped article Cd (this is in the arrangement of the upper nozzle 61 and the lower nozzle 62 of the adhesive injection device 60). (Corresponding), the upper piston rod 71 and the lower piston rod 72 are attracted to the vicinity of this adhesive of the card-shaped article Cd, and are within the range where they are actually adhered on the tubular packaging material Ft and in the card sticking area. (See FIG. 8).

Further, in practice, since the card-shaped article Cd is adhered on the vertically sealed side edge portions folded back by the guide plate 24, it can be attached as shown in FIGS. 1 and 8. The upper end of the region and the preferred adhesive range is below the lower end of the guide plate 24.
At this time, the lower end (that is, the downstream end) of the filling cylinder 15 needs to be located below the lower end (that is, the outlet end) of the guide plate 24. With such a position, the card sticking area can be specified.
Further, it is preferable that an area equivalent to one card to be attached is secured on the filling cylinder 15 as a card attachment area below the lower end of the guide plate 24, and at least an adhesive is applied to the card-shaped article Cd. It is necessary that the extent of the bonding range to be formed is secured between the lower end of the filling cylinder 15 and the lower end of the guide plate 24.

In this way, since the card-shaped article Cd and the tubular packaging material Ft are bonded to each other in the adhesive region on the filling cylinder 15 described above, the card-shaped article Cd is supported while the tubular packaging material Ft is conveyed at high speed. Even if the card-shaped article Cd is attached at such a speed, it is possible to reduce the drop of the card-shaped article Cd due to improper attachment or contact with the horizontal sealing device 30, and it is possible to improve productivity.

[Cooperative operation of packaging machine and pasting machine]
In the packaging machine 10 of the present embodiment, the packaging material feeding device 17 feeds the packaging materials Fw and Ft in an intermittent operation. Therefore, the collaborative operation of the packaging machine 10 and the card sticking machine 40 in the present embodiment is repeatedly executed with the two steps of stopping and transporting the packaging material as a reference unit as follows.

First, as shown in FIG. 3, when the packaging material Ft is stopped, the lateral sealers 31 and 31 approach each other (positions of B and C in FIG. 7A), and the above-mentioned ironing operation and lateral sealing operation are performed. , Performs a disconnect operation. Further, the card-shaped article Cd is also affixed at the affixing positions by the upper and lower piston rods 71 and 72 of the card affixing device 70. In addition, the suction transfer arm 56 of the card transfer device 55 moves to the first position P1 and sucks one card-shaped article Cd from the card stocker 50.

On the other hand, as shown in FIG. 2, during the transportation of the packaging material Ft, the lateral sealers 31 and 31 are in the open positions so as not to obstruct the passage of the tubular packaging material Ft and the attached card-shaped article Cd. Evacuate (positions of A, D, and E in FIG. 7A). At the same time, the vertically sealed back-pasted portion or the vertically-sealed portion Fs is folded down by the guide plate 24 of the back-pasting device 23, and the transport is continued toward the card-attached position.
Further, the suction transfer arm 56 pivots to the second position P2 in a state where one card-shaped article Cd is sucked, and after being coated with the adhesive by the adhesive injection device 60, the card-shaped article Cd After the suction is completed, the card-shaped article Cd is naturally dropped to the third position while being guided by the left and right guide members 65 and 66. The naturally dropped card-shaped article Cd is attracted by the upper and lower piston rods 71 and 72 of the card sticking device 70 in the retracted position to prepare for the sticking operation at the next stop.

[Effect of this embodiment]
(1) According to the present embodiment, the pair of lateral sealers 31, 31 that perform the ironing operation in the card sticking area, which is the range in which the card-shaped article Cd is stuck by the card sticking device 70 separately installed outside. Since it is configured to be provided on the filling cylinder 15 within a range that does not interfere with the filling cylinder 15, high productivity can be provided even in the vertical bag-making filling and packaging machine 10 with an ironing function corresponding to card sticking. Can be done.

(2) Further, near the lower part of the vertical sealing device 20, a guide plate 24 of the back sticking device 23 that pushes down the vertically sealed side edge Fs toward the outer surface of the filling cylinder 15 is provided, and the filling cylinder is provided. The lower end of the back sticking device 23 is located below the lower end of the guide plate 24 of the back sticking device 23, and the upper end of the card sticking area is located below the lower end of the guide plate 24 of the back sticking device 23. Since it has been adopted, the vertical seal portion Fs can be firmly and quickly folded down with respect to the outer surface of the filling cylinder 15 by the back tension, and then the card-shaped article Cd can be attached onto the vertical seal portion Fs, so that the vertical seal portion Fs is firmly folded down. The card-shaped article Cd can be more reliably and quickly adhered onto the vertical seal portion, and moreover, sticking failure can be less likely to occur, so that the production efficiency can also be improved.

(3) Further, the sealing surface 20A of the vertical sealer 21 and the sealing surface 31A of the horizontal sealer 31 are in a crossing relationship, and the card sticking area has a central area extending in the transport direction on both sides of the vertical sealing. When configured to be located along the folded base Fs'' of the edge Fs, the vertically sealed portion Fs coming out of the vertical sealing device 20 is relative to the sealing surface 31A of the horizontal sealer 31. Since the card-shaped articles Cd will pass in parallel, the attached card-shaped article Cd will pass in parallel with the sealing surfaces 31A of the horizontal sealers 31 and 31, and will come into contact with the horizontal sealers and fall. Can be easily prevented, which can increase productivity.

(4) Since the card-shaped article Cd is formed by being adhered to all or a part of the portion along the folded base portion Fs'' in the central region thereof extending vertically, the card-shaped article Cd is formed into a card shape. The distance from the adhesive portion of the article Cd to both side edges thereof can be shortened, and even when the card-shaped article Cd is transported at high speed, the side edge region of the card-shaped article Cd can be reduced from fluttering. As a result, the lateral sealers 31 and 31 can be passed smoothly, so that the productivity can be further improved.

(5) Further, the range in which the card sticking is not interfered by the squeezing motion of the lateral sealers 31 and 31 is the magnitude of the ascending / descending movement related to the squeezing motion of the lateral sealers 31 and 31, and the lateral sealer 31. Since it is specified based on the external dimensions of the parts (shutter mechanism 32 and ironing mechanism 33) that move together with 31, it is possible to more reliably set the card sticking area that does not receive such interference based on this. it can. In particular, even when the shutter plate 32C and the ironing plate 33C are separately provided on the upper and lower portions of the horizontal sealers 31 and 31, the card sticking area can be set more reliably, and therefore the packaging machine with high productivity. Can be realized more reliably.

The present invention may be modified and modified without departing from the scope and gist of the invention described in the claims. Therefore, these modifications and modifications are also included in the claims.

[Second Embodiment]
In the first embodiment, the packaging material feeding device 17 feeds the packaging materials Fw and Ft in an intermittent operation, but the present invention is not limited to this. For example, the present invention can cope with the case where the packaging material feeding device 17 does not completely stop the packaging materials Fw and Ft but feeds them in a slow and fast manner.

In this case, the range in which the lateral sealers 31 and 31 move up and down can be specified based on the figure shown in FIG. FIG. 9A is an explanatory diagram of the ironing operation and the sealing operation, similarly to FIG. 7A.
In this case, the difference is that when the lateral sealers 31 and 31 are squeezing from the point B to the point C, the tubular packaging material Ft is moving together (however, the lateral sealers 31 and 31). The moving speed of the tubular packaging material Ft is faster than the carrying speed of the tubular packaging material Ft). Therefore, the actual ironing distance is the distance obtained by subtracting "relative velocity x time" from the distance a between the points BC shown in FIG. 9B.
Further, the ironing operation is completed at the point C, and the sealing operation is performed from this point C to the point E. At this time, the horizontal sealers 31 and 31 and the tubular packaging material Ft are moving at the same speed. (That is, the relative velocity is zero). Accordingly, CD distance _{b 1} and DE distance _{b 2} of FIG. 9 (B), the sealer 31 and 31, although slowly lowered for sealing operation, no relative movement tubular packaging material Ft. The point D is a place where cutting is executed.

Therefore, it is possible to determine the range in which the seal interferes by the ironing operation, as in the case where the packaging materials Fw and Ft are operated intermittently. However, the actual squeezing distance is "a-relative velocity x time".
Therefore, unlike the case of the first embodiment, the lower end (downstream side end) of the preferable adhesive range is "(ironing distance a-relative velocity x time) + upper surface of the shutter plate from the center of the lateral sealer" rather than the cutting position. It is located upstream by the distance h _{1 ”.} On the other hand, the upper end (upstream side end) of the preferable adhesive range is the same as that of the first embodiment, and is a position separated downstream _{from the cutting position by "distance h 2 from the center of the lateral sealer to the lower surface of the ironing plate".} It is in. If the card sticking area is set within such a range, the packaging machine 10 with high productivity can be provided without interfering between the card sticking and the horizontal stickers 31 and 31.

[Other Embodiments]
In each embodiment, the vertical bag-making filling / packaging machine 10 according to the present invention has been described together with the card affixing machine connected to the packaging machine to attach a card-shaped article. It can also be described as a system including the above-mentioned card sticking machine.
In this case, the vertical bag-making filling / wrapping machine system with a card sticking function is configured to include a card sticking machine 40 attached to the vertical bag-making filling / wrapping machine 10, and the card sticking machine 40 is the card. It is characterized by comprising a card sticking device 70 that linearly moves and presses the card-shaped article Cd toward the card sticking area when the shaped article Cd is stuck to the tubular packaging material Ft. As a result, it is possible to realize a vertical bag-making filling and packaging system having both a high-speed processing and highly productive ironing function and a card sticking function.

According to the present invention, the vertical bag-making filling and packaging machine can be widely used in various fields in which it is required to attach a card or an article having a similar shape to bags.
