DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous package having a continuous packaging bag in which articles such as disposable chopsticks, spoons and the like are sealed at regular intervals in a synthetic resin band film, and a bulk cut package and a continuous package thereof. To an automatic packaging machine.

[0002]

2. Description of the Related Art The inventor of the present invention has previously filed a patent application for a disposable chopstick automatic wrapping apparatus capable of wrapping articles such as chopsticks in a continuous form using a synthetic resin band film (Japanese Patent Laid-Open No. 8-48308).
are doing. Here, one of the band films Fb is bent into a convex shape at regular intervals in the longitudinal direction to form a small bag portion Q,
An article P such as disposable chopsticks is stored in the small bag portion, and the other flat band film Fa is superimposed on the band film Fb, and the periphery of the small bag portion Q is heat-sealed so that the article is sealed. ing. The continuous packaging bag R having such a packaging form has the advantage that the film is hardly wrinkled in the main part and the appearance is good while using the flat film, and the sealing property of the sealing part is well maintained. In addition, when a product name or the like is printed on the film surface in advance, there are many advantages such that the printed portion is hardly displaced.

[0003]

However, in order to form a small bag portion Q as shown in FIG. 13 (a) from a flat film, the lower band film Fb is inevitably placed near both sides of FIG. 13 (b). ) Occurs, and this may become a problem at the time of cutting. On both sides of the pouch portion Q, the folded portion 9 spreads, and when the cut portion is cut along the line VII-VII in FIG. 14, the folded portion 9 is cut, and a hole O (FIG. 15) is opened in the pouch portion Q to cause a failure. It will be lost. Furthermore,
Heat seal width e2 in the width direction of the continuous packaging bag R (see FIG. 11)
In some cases, there is a case where there is a seal margin for securing the sealability after cutting the pieces, and the above problem is more likely to appear as the width e2 is reduced. In order to solve such a problem,
The present applicant has already proposed a solution in Japanese Patent Application Laid-Open No. Hei 10-291507, but it is difficult when a thicker lower band film Fb is employed or when the rigidity of the band film is high. A case has come out. Further, if the height of the small bag portion Q is larger than the chopsticks and the height of the small bag portion Q is required as in the case of the article P such as a fork, not only the hole O is easily formed but also the bulging portion of the lower band film Fb. The formation of the barrel itself has also emerged as a difficult problem.

[0004] The present invention solves the above problems,
With regard to such a specific continuous packaging bag in which a small bag portion is formed by a belt film, a continuous packaged product capable of securely storing articles without giving out perforation defects, without being restricted by the properties of the strip film and the size of the articles, and It is an object of the present invention to provide an automatic packaging machine for bulk cut products and continuous packages.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a continuous packaged product according to the present invention, a bulk cut packaged product thereof, and an automatic packaging machine for the continuous packaged product will be described in detail. (1) Automatic packaging machine for continuous packaged products FIGS. 1 to 10 show an embodiment of an automatic packaging machine for continuous packaged products according to the present invention (hereinafter simply referred to as "automatic packaging machine"). FIG. FIG. 2 is an enlarged view showing the positional relationship between the pressing roller and the belt wheel, FIG. 3 is an enlarged view showing the positional relationship between the transport mechanism, the widthwise heat seal mechanism, and the two-sided heat seal mechanism;
4 is a rear view of the disk-shaped body, FIG. 5 is a plan view of a transport mechanism near the disk-shaped body, FIG. 6 is a side view of a main part of FIG. 3, and FIGS. Enlarged view in which is progressing,
FIG. 9 is a partial perspective view showing the positional relationship between the disk, the plate, and the belt at the side edges of the band film, and FIG. 10 is a side view of the continuous packaged product.

[0008] The automatic packaging machine for continuous packaged goods comprises a conveyor 1, a pressing roller 4, a width direction heat sealing mechanism 2, and a both side heat sealing mechanism 3. Conveyor 1 consists of a belt conveyor,
It is arranged horizontally in the middle of the frame 85 (FIG. 1). In the conveyor 1, a belt 14 is wound around two belt wheels 11, 12, and the belt wheel 11 is driven by a motor (not shown). The transporter supports the article P to be dispensed and transports the article P and the band films Fa and Fb from the receiving point Z of the article to a place where the article is packed and sealed. The belt 14
On the upper side, a prism-shaped projection 13 which is orthogonal to the traveling direction and forms a storage recess u of the small bag portion Q of the continuous packaging bag at regular intervals is integrally fixed. The projections 13 are arranged at regular intervals in the longitudinal direction of the band film Fb. The specific distance L2 between the projections is determined by the pitch of the packaging bag that stores the article P (FIG. 2). Since the width g of the protrusion 13 in the form of a prism is substantially equal to the width of the heat sealing portion S1 in the width direction, the protrusion 13 is selected based on this. In the present embodiment, four belts 14 with a predetermined interval are wound around a belt wheel,
The protruding body 13 is fixed to the four belts 14 at right angles to each other to form a protruding belt 14 (FIG. 5). The length of the protrusion is longer than the width W1 of the band film, and the length of the band film Fa, Fb
Projecting end 131 protrudes from both sides. For this reason, the belt 14 with protrusions is slightly different in shape, but has a shape in which a track runs on a sleeper, and a protrusion 13 that hits a sleeper and a belt 14 that is slightly wider than the track but hits the track. And it is like a double track running four parallel. However, here, the protrusion 13 corresponding to the sleeper is located above the belt 14. Further, a circular hole 141 is formed on the belt surface serving as the bottom surface of the recess u (FIGS. 2 and 5).
This automatic wrapping machine includes a lower band film Fb on the protruding belt 14, an article P thereon, and an upper band film Fa (upper and lower bands) drawn out from a tape reel F2 above the conveyor 1. The band width of the films Fa and Fb is the same.) The guide roller 89 covers the article P. Thereafter, the periphery of the small bag portion Q is sealed by the width direction heat sealing mechanism 2 and the both-side heat sealing mechanism 3 to form a continuous packaged product R. Upstream side of the conveyor 1 (left side in FIG. 1)
The pressing roller 4 is arranged right beside the belt, from which the belt 14
, A receiving position Z of the article P, a widthwise heat seal mechanism 2 and both-side heat seal mechanisms 3, a rotary blade 6, and a cutter device 7 are arranged in this order. Note that the present embodiment is different from FIG.
, The articles P are packaged and sealed in two rows,
In the receiving position Z, 7 × 2 rows (a total of 14) articles P are intermittently fed into the concave portion u of the belt 14 with protrusions, that is, the small bag portion Q of the lower band film. The lower belt film Fb receives the articles P arranged in two rows, and the four belts 14 support one of the articles P arranged in one row and one of the lower belt films Fb. The article P here is a fork which is higher in height and larger in size than disposable chopsticks or the like.

The pressing roller 4 is used to drive the two belt wheels 1.
A rotating shaft 4a is disposed on a surface connecting the two rotating shafts 11a and 12b, and a convex portion 41 corresponding to the concave portion u is formed on the surface. (Fig. 2). Three rotating shafts 11a, 12
b and 4a are parallel. The pressing roller 4 is arranged beside the belt conveyor 1 so as to be in contact with the belt conveyor 1, and the pressing roller 4 meshes with the belt 14 with the protrusion at this point. Between the pressing roller 4 and the belt conveyor 1, a tension roller and a feed roller 8 are provided by a tape reel F1 disposed below the conveyor 1.
8, the lower band film Fb is fed. Due to the engagement between the pressing roller 4 and the belt conveyor 1 (the belt 14 with the protrusions), the lower band film Fb forms a small bag portion Q that bulges in a continuous packaging bag. Here, the protrusion 13
It is generally difficult to form a deep pouch portion Q along the belt 14, but in the present invention, this is solved by placing the pressing rollers 4 in a side-by-side state in contact with the conveyor 1. In the meshing portion, the pressing roller 4 is driven by the belt wheel 1.
2, the opening between the projections 13 is opened most by the belt wheel 12 (L1 in FIG. 2).
In addition, in the process of moving away from the position of the belt wheel 12 to the receiving position Z of the article P, the opening between the projections 13 becomes the normal interval of L2 smaller than L1. Therefore, the pouch portion Q has a sufficient size to fit the article P. Further, the belt wheel 12 is appropriately provided with an intake hole 121 at a position corresponding to the hole 141 of the belt 14, and the small bag portion Q is easily stored in the concave portion u by suction suction using the intake hole. ing. Therefore, the floating portion α formed at the stage of forming the small bag portion Q in combination with the above operation can be eliminated. In FIG. 2, the lower band film Fb is somewhat separated in order to show the positional relationship between the projection 13 and the belt 14, but the lower band film Fb has advanced to the receiving position Z of the article P. At this point, even if the small bag portion Q becomes high, the small bag portion Q which swells in a convex shape at regular intervals even if the small bag portion Q becomes high is reliably formed.

The width direction heat sealing mechanism 2 is disposed on the conveyor 1 (projection 13) at the receiving position Z of the article P and downstream of the upper band film Fa, and is disposed in the width direction heat sealing portion S1 of the continuous packaging bag. Is formed. Width direction heat sealing mechanism 2
Includes a disk-shaped body 21 and an air cylinder 23. Frame 8
Four pillars 24 are erected from the base 32 at the middle stage of 5 over the conveyor 1, and a top plate 25 is fixed to the upper ends of the pillars (FIG. 1). Then, the air cylinder 23 is attached to the back surface of the top plate. A board-shaped body 21 horizontally arranged with its lower surface facing the belt surface is attached to a rod 23a of the air cylinder 23 via a substrate 22 (FIG. 3). Disc 2
1, the width W2 is slightly wider than the width W1 of the lower band film Fb that receives the articles P by arranging the articles P in two rows on the belt 14 with protrusions (FIG. 4). Width W2 of board
Is substantially equal to the length of the protrusion 13, and can cover the upper and lower band films Fa and Fb in the width direction. Also,
The length of the plate-shaped body 21 in the traveling direction of the band film Fb has a length that can heat seal seven articles P at one time.
A depression C is formed on the lower surface of the disc-shaped body at a position corresponding to the small articles Q of the seven articles P × 2 rows on the belt 14 with the projections. Then, the lower surface of the disc-shaped body has a width direction portion 21a corresponding to the width direction heat seal portion S1 of the continuous packaged product R, and both side portions 21b corresponding to both side heat seal portions S2 of the continuous packaged product R,
The center part 2 of the center line where the articles P are arranged in two rows
1c (corresponding to both side portions 21b of the small bag portion Q) is made a flat surface, and these surfaces can be heated by a heater (not shown). Further, the disc-shaped body 21 is configured to be able to move up and down by operating an air cylinder 23 and to be pressed and joined to the upper surfaces of the eight (plural) projections 13 by descending (FIG. 5). Thus, the lower band film Fb, the article P, and the upper band film are laid on the belt 14 with the projections, and the board-like body 21 is lowered and pressed against the projections 13, so that the widthwise heat seal portion S1 of the continuous packaging bag is formed. Can be finished. In the present embodiment, the width direction portion 21a and the eight protrusions 1
3 are pressed against each other, thereby forming eight lines of the heat seal portion S1 in the width direction at a time. When the board 21 is lowered and pressed and joined to the projection 13, the liner 5 for supporting the projection 13 is provided on the frame 85 so that the belt 14 with the projection does not sink down by the pressing. (FIG. 6). Liner 5
Has the same shape as the protruding body 13, but has a shape in which the belt portion is cut off at the upper edge thereof. The liner 5 is disposed so as to face the protrusion 13 of the belt 14 with a protrusion that intermittently stops below the disk-shaped body 21. Also, the upper and lower band films Fa, Fb
In order to ensure that the heat-sealing of the two-band films Fa and Fb can be performed by pressing and joining the plate-like body 21 to the projection 13 with the heat treatment, heat resistance is provided above the projection 13. A rubber member 13a is attached (see FIG. 2).

The two-sided heat sealing mechanism 3 includes a band film Fa,
Fb is disposed below the protruding belt 14 on the upper side of the conveyor 1 at both side edges in the longitudinal direction (here, including a center line for arranging the articles P in two rows), and can be moved up and down by The plate 31 passes through between the protrusions and between the belts, and the upper surface of the plate comes into contact with the plate-shaped body 21 in a lowered state to form a seal on both sides of the small bag portion Q. The two-sided heat sealing mechanism 3 includes a plate 31 and an air cylinder 33 (FIG. 1). An air cylinder 33 is mounted on the base 32, and a horizontally arranged plate-like base 35 is attached to a tip of a rod 33 a of the air cylinder 33. And the base part 3
The three plate bodies 31 are fixed on the upright 5 in an upright state. The three plate members 31 are located below the protrusions 13 in such a manner as to evade the belt 14 on the upper side of the conveyor 1, and the upper surfaces 311 thereof oppose the bottom surfaces of both side portions 21 b, 21 b and the center portion 21 c of the disk-shaped member 21. (FIG. 6). The plate body 31 has an upper part of a rectangular plate in a comb-like shape, and a protruding portion 31a thereof.
The length N1 is substantially equal to the distance L1 between the projections, so that the projections 13 can be fitted (FIGS. 3 and 9). The concave portion 31b of the plate body is formed such that the concave width N2 is slightly larger than the protrusion width g, and the upper surface 311 of the projecting portion which protrudes in a U-shape as shown in FIG. Cut out so that it can be joined to. The plate thickness t of the plate body 31 corresponds to the thickness of each of the side portions 21b and the center portion 21c. With such a configuration, when the plate body 31 is pressed against the board-like body 21 in the lowered state to form a seal on both sides of the small bag portion Q, the small bag portion Q is shielded on both sides by the protrusions 13 as shown in FIG. Therefore, the band film portions Fbe on both sides of the pouch portion lose their escape irrespective of their thickness and properties, and the folded portion 9 is accommodated substantially within the width of the pouch portion Q and is joined and sealed to the upper band film Fa. Becomes Here, the plate body 31 of the double-sided heat seal mechanism 3 abuts the board-shaped body 21 to perform the double-sided heat seal portions S2 for 2 rows × 7 continuous packaging bags at a time. Note that a heat-resistant rubber material (not shown) similar to the protrusion 13 is also attached to the upper portion of the plate 31.

Thus, the conveyor 1 is pressed by the pressing roller 4.
A small bag portion Q is formed on the lower band film Fb at regular intervals in the longitudinal direction, an article P is stored in the small bag portion Q, and the upper flat band film Fa is further added to the band film Fb. By superimposing the seals S1 and S2 around the small bag portion Q, a continuous packaged product R in which a continuous packaging bag enclosing the article P is formed can be produced.

In the automatic packaging machine of this embodiment, the shape of the small bag portion Q formed by the pressing roller 4 is
The suction body 86 is formed between the belt wheel 12 and the seal mechanisms 2 and 3 so as to be substantially in contact with the lower surfaces of the four belts, so as to maintain the suction body 86 until it reaches 3 (FIG. 8). An opening 861 is appropriately provided on the upper surface of the suction body corresponding to the hole 141 of the belt, and the suction bag 862 is depressurized so that the small bag portion Q is reliably convexly bulged. In addition, the known rotary blade 6
And the known cutter device 7 to make the continuous packaged product R a piece-by-piece package K. A rotary blade 6 and a cutter device 7 are arranged downstream of the conveyor 1 downstream of the widthwise heat seal mechanism 2 and the heat seal mechanisms 3 on both sides.

Next, the operation of the automatic packaging machine will be described.
First, the motor is started to operate the conveyor 1 intermittently, and the lower band film Fb is fed out onto the conveyor 1 from the tape reel F1 via the pressing roller 4, and the fixed interval is established by the engagement between the pressing roller 4 and the projection 13. In this case, a small bag portion Q is formed.
Then, at the receiving location Z of the article P to which the conveyor 1 is traveling,
When the conveyor 1 is temporarily stopped, the articles P (7 ×
2 rows). Thereafter, the conveyor 1 advances, and the upper band film Fa from the tape reel F2 covers the article P and the lower band film Fb at the guide roller 89.

With such a state secured, the process reaches the next widthwise heat sealing mechanism 2. Conveyor 1 goes on, 7
When the articles P of two pieces × 2 rows are located immediately below the disk-shaped body 21, the articles P are intermittently stopped again (FIG. 3). Thereafter, the air cylinder 23 is actuated, the rod 23a is extended, and the plate-like body 21 whose lower surface is in a heated state is lowered to sandwich the upper and lower band films Fa and Fb with the protruding body 13 and heat seal them together. Projection 1
3 comes into contact with the widthwise portion 21a of the board-like body 21 to complete the widthwise heat seal portion S1 of the continuous packaging bag (FIG. 7). Since the width direction heat seal portion S1 has a length of the protruding body 13 and a width W2 of the disc-shaped body 21 larger than the width of the band films Fa and Fb,
It is formed so as to completely cross the band films Fa and Fb.

Subsequently, the air cylinder 33 is operated while the board 21 is in the lowered state, and the plate 31 is moved upward (FIG. 9). The plate 31 fits between the protrusions while the protrusions 31a dodge the protrusions 13, and pushes up both side edges Fbe of the pouch portion Q of the lower band film Fb between the protrusions. Both side edges Fbe cannot be expanded in the lateral direction because both sides are restricted by the projections 13. As the plate 31 further moves upward, the both side edges Fbe are folded within the width between the projections, joined and sealed, and both side heat seal portions S2 are formed at both side edges Fbe of the pouch portion Q (FIG. 8). ). The side edges Fbe of the band films Fa and Fb, which make each packaging bag, are sealed to form a heat-sealed portion S2 on both sides. Although the heat seal portions S2 on both sides are slightly different in the shape of the folded portion due to the clearance between the projection 13 and the plate 31, etc., the folded portion 9 fits within substantially the width of the small bag portion Q (FIG. 10). Due to manufacturing, when the package K is obtained, the leading end 9a of the folded portion 9 is placed in the small bag portion Q.
Even if it slightly protrudes from the width to the width direction heat seal portion S2, it is within the scope of the present invention. The width e for cutting the widthwise heat seal portion S2 without making a hole O in the pouch portion Q can be sufficiently secured,
This is because they have the same technical idea. Then, the rod 23
a, 33a are shrunk, and the plate-shaped body 21 and the plate body 31 are opened,
As shown in FIG. 6, the article P is stored in the small bag portion Q, and a continuous packaged product R in which the periphery of the small bag portion Q is sealed is completed. In the present embodiment, the continuous packaged product R further crosses the conveyor 1, is guided by a guide roller (not shown) and enters the rotary blade 6, and firstly, the continuous packaged product R, which is arranged in two rows, is located at the center. The line is divided into two continuous packages R. After that, the cutter device 7 is used to make the loose-cut package K in which the articles P are stored one by one. The product that has become the loose cut package K is transported to the receiving tray 82 and packed in a box.

(2) Continuous packaged product and bulk cut packaged product The continuous packaged product R manufactured as described above has a small bag portion Q which bulges in a convex shape with the lower band film Fb at regular intervals in the longitudinal direction. A continuous packaging bag in which the article P is formed by forming and accommodating the article P in the small bag portion Q, and by superimposing a flat upper band film Fa on the lower band film Fb and sealing the periphery of the small bag portion Q. Is formed, and the both side seal portions S2 of the lower band fill Fb on which the small bag portion Q is formed as shown in FIG. 11 are folded within the width e1 of the small bag portion Q substantially. The overlapping portion 9 is housed and bonded and sealed to the upper band film Fa (FIG. 11).
The cutter device 7 cuts the heat-sealed portion S1 in the width direction of the continuous packaged product R, divides it into one small bag portion Q, and encloses one piece of product P. Both side seal portions S2 of Fb are formed such that the folded portions 9 are accommodated within the width of the small bag portion Q and are bonded and sealed to the upper band film Fa (FIG. 12). 6 to 15, the width direction heat seal portion S1 and both side heat seal portions S2 are used.
Although the upper and lower band films Fa and Fb are bonded to each other, the two are separated from each other or the length of the upper and lower band films Fa and Fb is changed here for convenience.

(3) Effect The continuous wrapping product thus configured, the loose-cut wrapping product thereof, and the automatic wrapping machine for the continuous wrapping product are provided with the band films Fa,
At both longitudinal edges of Fb, the protrusion 13 is recessed 31
b, the projections 31a of the plate 31 are fitted between the projections and press the upper surface 311 of the plate-shaped body 21 in a lowered state to seal both sides of the small bag portion Q. The body 13 acts as a shielding wall, and the slack portions on both sides of the pouch portion Q (both side edges Fbe of the lower band film Fb) are crushed between the projections to form a folded portion 9 within the width between the projections. I do. Therefore, when cutting the widthwise heat seal portion S1, there is enough zone e2 to prevent the folded portion 9 from being cut, so that a problem of opening the hole O in the small bag portion Q does not occur. In the present invention, the folded portion 9 is substantially within the width of the small bag portion Q, and even if the leading end portion 9a of the folded portion 9 slightly protrudes from the width of the small bag portion Q due to manufacturing reasons, the width direction heat seal portion S1 is formed. Can be sufficiently secured, and there is no need to worry about opening the hole O in the small bag portion Q in the loosening process by the cutter device 7.
Further, according to the present invention, the heat seal width e2 of the width direction heat seal portion S1 only needs to be able to secure a seal margin, and is not limited by the folded portion 9 as in the conventional case, and the width e2 can be reduced to be continuous. The productivity of the package is improved. In addition, since the folded portion 9 fits within substantially the width of the small bag portion Q, there is no restriction on the thickness of the band film and its material as in JP-A-10-291507. In addition, small bag part Q
When the pressing roller 4 and the belt 14 with a projection are meshed with each other, the projections are largely spaced apart from each other and then closed at regular intervals. You can easily make it. And
The pouch portion Q has a belt hole 141, a belt wheel intake hole 121,
By the suction body 86, the shape of the small bag portion Q that swells in a convex shape can be maintained up to the sealing mechanisms 2 and 3, that is, until the continuous packaged product R is manufactured.

It should be noted that the present invention is not limited to the embodiment described above, but can be variously modified within the scope of the present invention depending on the purpose and application. Conveyor 1, heat sealing mechanism in width direction 2,
The shape, size, etc. of the heat sealing mechanism on both sides 3, the pressing roller 4, the folding section 9, the package K, the continuous packaging bag R, the small bag section Q, the article P, etc. can be appropriately selected according to the application. The conveyor 1 includes a chain conveyor. The article P is not limited to the fork of the embodiment, but may be any object such as a spoon and chopsticks.

[0020]

As described above, the continuous wrapping product according to the present invention, the loose-cut wrapping product thereof, and the automatic wrapping machine for the continuous wrapping product are not limited to the size and height of the continuous wrapping bag in which the small bag portion is formed by the band film. It is possible to easily form a small bag portion that can store articles regardless of the size, and it is also possible to reliably cut and cut into loose cut packages without making a hole in the small bag portion, and to achieve an excellent effect.
