Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for packaging a sandwich having various kinds of adhesive materials and sticky seasonings exposed on its surface, and a packaging apparatus therefor.

[0002]

2. Description of the Related Art Conventionally, for example, a method for packaging bread having an adhesive seasoning or the like exposed on the surface is disclosed in Japanese Patent Publication No. Sho 64-64.
There is a method disclosed in Japanese Patent No. 9233, and in recent years, such a packaging method has been used for the packaging of a sandwich in which an adhesive material sandwiched in order to increase the consumer's willingness to purchase is exposed on the surface (inclined surface). It is being supplied to the market.

That is, as shown in FIG. 5, the packaging method described in the above publication discloses a transparent outer film capable of heat-sealing a bread body 13 in which an adhering seasoning 12 is applied to an upper portion of an outer surface.
14 wrapped, then wrapped outer film 14 opposite ends
When the bread 13 is packaged by heat-sealing a three-way portion 14a and a portion 14b between the both end portions 14a, the portion of the bread body 13 covered with the seasoning 12 may be covered with the seasoning 12. A transparent film having a size that can be formed as a sealing portion at both end portions 15a facing each other is formed as an inner film 15, and then the inner film 15 and the pan 13 are connected to the transparent outer film.
Then, the bread body 13 on which both ends 15a of the inner film 15 and both ends 14a of the transparent outer film 14 are polymerized and sealed at both ends of the outer film 14 wrapped and sealed and coated with an adhesive seasoning is then formed. It is to be packed.

[0004] Therefore, according to such a packaging method, since the seasoning 12 is covered and protected by the inner film 15,
The seasoning 12 does not directly rub against the inner surface of the outer film 14, thereby preventing the seasoning 12 from adhering to a part or the entire inner surface of the outer film 14, and thus being stored in the outer film 14. When the bread 13 thus obtained is viewed from the outside, it is possible to obtain a package 16 of the bread body with good appearance.

[0005]

However, the following problems have occurred in the packaged bread body obtained by the above-described packaging method.

That is, since the inner film 15 is attached to the seasoning 12 applied to the upper portion of the outer surface of the bread body 13 housed in the outer film 14 as described above, the seasoning 12 is Although it is in a state of being covered and protected by the inner film 15 without directly rubbing against the inner surface of the
Both ends 15a of the inner film 15 are formed by overlapping with and sealing both ends 14a of the outer film 14 at both ends of the outer film 14 surrounding the bread body 13.

Therefore, for example, the inner bread
When 13 moves to either side of the both ends 14a of the outer film 14, the inner film 15 attached to the seasoning 12 necessarily moves to one side simultaneously with the moving direction of the bread body 13. However, at this time, both ends 15a of the inner film 15 are sealed by overlapping with both ends 14a of the outer film 14 at both ends of the outer film 14 wrapping the bread body 13. The other end 15a of the inner film 15 is connected to the other end 14a of the outer film 14 via the seal portion.
Although it is possible to prevent the seasoning 12 from directly rubbing against the inner surface of the outer film 14 within the allowable deformation range of the outer film 14 by pulling and deforming the package 16 to one side so that the entire length of the package 16 is reduced, If the end portions 14a of the outer film 14 are restrained for some reason during packing or transporting the packaged product 16 or the amount of movement of the pan 13 exceeds the allowable deformation range of the outer film 14. The end portion 15a of the inner film 15 moving in the outer film 14.
The end 14a of the outer film 14 through the seal
Cannot be pulled and deformed so that the entire length of the frame is reduced.

Accordingly, when the end portion 14a of the outer film 14 cannot be pulled and deformed so as to shrink the entire length of the packaged product 16 via the sealing portion at the end portion 15a of the inner film 15 moving in the outer film 14. In the meantime, the bread body 13 naturally moves in a predetermined direction while rubbing the seasoning 12 against the inner surface of the inner film 15, and as a result, the inner surface of the inner film 15 is soiled.

Therefore, according to the packaged product 16 using the above-described packaging method, the bread body 13 is not only in a state where the both ends 14a of the outer film 14 are restrained but also in a state where the deformation of the outer film 14 is allowed.
If the inner body 15 moves along both ends of the outer film 14, the inner surface of the inner film 15 becomes dirty, and when the bread body 13 stored in the outer film 14 is viewed from the outside, the inner surface becomes The packaged product 16 of the bread body 13 having a good appearance with the dirty inner film 15 being visible through the outer film 14
The problem of not being able to obtain
This was a problem that had to be solved, as was the case with sandwich packaging using this packaging method.

[0010] The present invention has been made to solve the above problems, and a film is placed on the surface (inclined surface) of a sandwich in which various kinds of adhesive materials and adhesive seasonings are exposed. Because it is stored and packed in the bag body, even if each part of the bag body is placed in an undeformed state,
Further, not only when the bag body is made of a material that is not easily deformed, but also when the sandwich moves in the bag body, the film adhered to the adhesive material or the adhesive seasoning. An adhesive material or adhesive flavoring agent is rubbed on the inner surface of the product via a moving sandwich to ensure that the inner surface is not soiled and to increase the consumer's willingness to purchase at any time. It is an object of the present invention to provide an extremely excellent sandwich packaging method and a packaging apparatus capable of obtaining a large amount of good-looking sandwich packaging products in which seasonings are exposed on the surface by a simple packaging operation. .

[0011]

That is, the present invention has been made in order to solve the above-mentioned problems, and a method of packaging a sandwich for solving the problems is to provide various kinds of sandwiching methods for the hanging film piece 9a. A sheet obtained by transferring the sandwich 7 so that the surface 7a of the sandwich 7 where the adhesive material or the adhesive seasoning is exposed is brought into contact, and then cutting the film piece 9a in contact with the surface 7a into a predetermined length. After dropping the film 9b onto the surface 7a and covering the surface 7a, the sandwich 7 is fed into the bag body 1 and packaged, so that various adhesive materials 8 and adhesive seasonings are exposed. In the state where the film 9b is placed on the surface 7a of the sandwich 7 and stored and packaged in the bag body 1, for example,
When the sandwich 7 is moved in the bag body 1 when the respective parts are placed in a state where they are not deformed or when the bag body is made of a material that is not easily deformed. Even when the film 9b is in a free state without being restrained by the bag body 1, the surface 7a of the sandwich 7 is free.
Is free to move in the bag body together with the sandwich 7.

Therefore, since the film 9b moves freely in the bag body 1 together with the sandwich 7 in a free state without being restrained at the end by the bag body 1, the film adhered to the tacky material or the sticky seasoning. The adhesive material 8 and the adhesive seasoning are rubbed on the inner surface of the 9b via the moving sandwich 7, so that the inner surface can be reliably prevented from being soiled.

Therefore, even when the sandwich 7 accommodated in the bag body 1 is directly viewed from the outside, the surface 7a of the sandwich 7 on which the film 9b is mounted is exposed to the bag body 1 and the film 7b. 9b It can be checked from outside the bag body 1 in any beautiful condition at any time, so that the sticky material 8 and the adhesive seasoning sandwiched in order to increase the consumer's willingness to purchase are exposed on the surface. There is an advantage that a large amount of sandwich products with good quality can be obtained by a simple packaging operation.

Reference numeral 22 denotes a film abutment, which is a sandwich 7 of the film piece 9a delivered in a hanging state as described above.
The film abutment plate 22 is rotatably supported (arrow C) and suspended from an upper position near the other surface 9d opposite to the one surface 9c opposite to the surface 7a. At least one of the film piece 9a or a sheet-like film 9b obtained by cutting the film piece 9a through the nichrome heating wire 21 is placed on the surface 7a of the coming sandwich 7 with the movement of the sandwich 7 to the surface 7a. The film piece 9a or the sheet-like film 9b obtained by cutting the film piece 9a through the nichrome heating wire 21 is brought into close contact with the adhesive material 8 exposed on the surface 7a by pressing from the lower side to the upper side. It is for.

The bag body, the sandwich, and the packaging device used in the first embodiment of the present invention have the above-described configurations. The sandwich is housed in the bag body having the following configuration, and the adhesive material is exposed. A case will be described in which a good-looking package that can be checked from outside the bag body in a clean state at any time through a sheet-like film is obtained.

First, as shown in FIG. 3 (a), the sandwich 7 is moved through the guide table 17c so that the surface 7a of the sandwich 7 where the various adhesive materials 8 are exposed is brought into contact with the hanging film piece 9a. To transfer (arrow F).

Thereafter, as shown in FIG.
The lower end of the film piece 9a comes in contact with the
With the movement (arrow G), the film abutment plate 22 starts to rotate (arrow I) while pressing one surface 9c of the film piece 9a against the adhesive material 8 from below to above the surface 7a of the sandwich 7. In the state of being cut, the film piece 9a is cut through the nichrome heating wire 21 to a predetermined length capable of substantially covering the surface 7a, and the sheet-like film 9b obtained by the cutting is cut into the surface 7a. By dropping (arrow H) on the surface
The sheet-like film 9b dropped on 7a is sandwiched
By pressing against the adhesive material 8 exposed on the surface 7a, the sheet-like film 9b can be adhered to the adhesive material 8 exposed on the surface 7a.

The sheet-like film 9b has a surface as described above.
When the sandwich 7 covered with 7a is detected by the sensor 26, air of a predetermined pressure is jetted from the blower nozzle 23, and as a result, the holding extension piece 3a is held via the bag holder 20, In addition, the opening 6 of the bag body 1 located at the uppermost position among the bag bodies 1 stacked in a large number in the superposed state is expanded so as to be opened via the jet air.

Therefore, as shown in FIG. 3C, the sheet-like film 9b has the surface inside the bag body 1 having the opening 6 opened.
After the sandwich 7 covered with 7a is fed into the bag body 1 without complicated opening work, the bag body 1 is subjected to a predetermined or more tensile force (arrow J), whereby the cutting perforations 3b are formed. The bag main body 1 can be separated from the bag holding extension piece 3a held by the bag holder 20 via the bag holder 20, but before or after the separating step, a new film can be cut off via the film feeder 19. The piece 9a is sent out (arrow K) so as to hang down, and the next sandwich 7 is awaited.

Thereafter, as shown in FIG. 1 (a), the opening 6a of the surplus portion of the bag body 1 protruding from the sandwich 7 housed in the bag body 1 is folded (not shown), and then folded. By attaching, for example, a sealing and unsealing tape (not shown) across the opened portion 6a shown in FIG.
As shown in (a), a package 10 in which the opening 6 of the bag body 1 in which the sandwich 7 is stored is sealed (not shown) can be obtained.

The package 10 obtained as described above is
The sandwich 7 is obtained by placing a sheet-like film 9b capable of substantially covering the surface 7a on the surface 7a of the sandwich 7 and then storing it in the bag body 1.

Therefore, for example, when the opening 6 of the bag body 1 is sealed, or when the inside sandwich 7 is compressed via external pressure to reduce its shape during transportation or the like, the inside of the bag body 1 is closed. A slight gap, a so-called space (arrow M), may be formed.

When a space (arrow M) is formed in the bag body 1 as described above, as shown in FIG.
The inner sandwich 7 moves through the space portion 17 (arrow M) during transportation or the like. Even if the sandwich 7 moves inside the bag body 1 even when the sandwich film 7 moves, the sheet-like film 9 b Is attached to the surface 7a of the bread body 7 in a free state without being restrained by the bag body 1, so that the sheet-like film 9b can move freely in the bag body 1 together with the sandwich 7. Becomes

Thus, in a state where the film 9b is placed on the surface 7a of the sandwich 7 where the various adhesive materials 8 are exposed, and is stored and packaged in the bag body 1, for example, the respective parts of the bag body 1 are not deformed. When the bag 7 is made of a material that does not easily deform, the film 9b remains in the bag 9 even when the sandwich 7 moves violently in the bag body 1. By being attached to the surface 7a of the sandwich 7 in a free state without being restrained at the end by the main body 1, the inside of the bag main body can freely move together with the sandwich 7.

Further, since the film 9b moves freely in the bag body 1 together with the sandwich 7 in a free state without being restrained at the end by the bag body 1, the inner surface of the film 9b adhered to the adhesive material 8 In addition, it is possible to reliably prevent the adhesive material 8 from being rubbed by the moving sandwich 7 and the inner surface thereof being soiled.

Therefore, even when the sandwich 7 accommodated in the bag body 1 is directly viewed from the outside, the surface 7a of the sandwich 7 on which the sheet-like film 9b is mounted, on which the adhesive material 8 is exposed, is regarded as the bag body 1. A good-looking sandwich that can be seen from the outside of the bag body 1 in a clean state through the film 9b at any time, and thus exposes the surface of the adhesive material 8 sandwiched between the films 9b at any time to increase the consumer's willingness to purchase. A large number of packages can be obtained by simple packaging operations.

In the above embodiment, the sheet-like film is attached to the surface of the sandwich where the adhesive material is exposed, but is not necessarily limited to the adhesive material. For example, the sheet-like film may be attached to the surface of the sandwich. , For example, creams, chocolates, etc., or various sticky seasonings that are beautifully patterned with them, may be applied to the exposed surface, and even in this case, The present invention has the advantage that it is possible to provide a good-looking sandwich package in which the adhesive flavoring agent attached to the surface is exposed on the surface so as to increase the purchase motivation.

Further, in the above embodiment, the bag body is made of a colorless and transparent film made of a uniaxially stretched polypropylene film. The point is that the consumer's willingness to purchase is visually recognized through the stain prevention sheet placed on the surface. It is not necessary to be colorless and transparent as long as the bare surface of the adhesive material or the surface to which the adhesive seasoning has been applied can be visually confirmed from the outside of the bag body or the container body in order to stir. Needless to say, a colored transparent or partially transparent portion may be provided.

Further, in the above embodiment, the sheet-like film is a flexible and fit thin film, for example,
It is made by using a non-stretched polypropylene film, but is not necessarily limited to this.When placed on the surface of the sandwich, the surface where the adhesive material or the adhesive seasoning is exposed through the sheet-like film is visually observed. As long as it can be confirmed, it is not always necessary to be colorless and transparent like the bag body, and it goes without saying that the sheet may be provided with colored transparent or partially transparent portions. The specific material, size, shape, etc., of the film-like film are not limited at all, but thin unstretched polypropylene in consideration of the adhesiveness with the adhesive material and the adhesive seasoning, and the workability of the packaging device. It is preferable to use a film.

Further, in the above embodiment, the support shaft is
For example, since the film is formed in a square shape in cross section to rotatably support the film by supporting four points of the inner peripheral wall of the core portion of the film wound in a roll shape having a predetermined outer diameter by point contact. Even when the film feeder is driven and the film is suddenly unwound and the roll-shaped film is rotated, the inner peripheral wall of the core portion slides around the four corners of the square where the support shaft is in point contact with the support shaft, and slides freely (core Since the four corners of the support shaft supporting the inner peripheral wall of the support shaft support the inner peripheral wall of the core by point contact, the contact frictional resistance can be extremely low. This can prevent extension deformation and division of the film, and as a result, the thickness of the film can be set to the minimum necessary, which has an advantage that cost can be reduced. But the support if the specific shape of the support shaft, not intended to be limiting in any way be structured by point contact the core inner circumferential wall of the film.

Further, in the above embodiment, a bag holder comprising a pair of opposed insertion pins is provided on one end side of the top plate provided on the base so as to sequentially hold the bag main body so as to be able to be taken out. In short, if a sandwich body whose surface is covered with a sheet-like film can be sent in so that the bag body capable of storing the sandwich can be sequentially taken out and held, if the sandwich body can be held through an elastic body or the like, A holding body (binder structure) that holds the bag holding extension piece in a holding state may be used. Even in this case, it is possible to hold the bag body, but from the viewpoint of cost and maintenance, etc. Preferably a pair of insertion pins,
It goes without saying that the specific structure, the number of sheets to be held and the holding state of the bag holder are not limited at all.

Further, in the above embodiment, the film feeder is composed of a pair of opposing film-holding drive rubber rollers and a motor for rotating and driving the film-holding drive rubber rollers. If it is possible to feed the free end of the film in one direction in a hanging state with a predetermined length without causing breakage or the like, only one rubber roller rotates and the other rubber roller follows. It may have a configuration, and it is not always necessary to use a rubber roller, and a roller formed of plastic may be used. The specific structure of the film feeder, the film feed speed, and the like are not necessarily limited. Considering the thickness (extremely thin), a pair of films that sandwich the film from one side and the other side and send it out Preferably used clamping drive rubber roller.

Further, in the above embodiment, a nichrome heating wire is used as a cutting means for cutting the hanging film piece into a predetermined length capable of substantially covering the surface of the sandwich, but not necessarily. It is not necessary to use a nichrome heating wire.For example, a method of cutting a film piece through a sandwiching mechanism, a push-off mechanism, a slide cutter mechanism, or the like to obtain a sheet-like film may be used. From the point of view, it is preferable to use a nichrome heating wire, and even when the cutting of the film piece by the cutting means is performed using various sensors, or when the sandwich is moved a predetermined distance toward the bag body side. In any case, the film piece pulled toward the bag body side through the sandwich is cut naturally.

Further, in the above embodiment, when a sensor using infrared rays or the like detects a sandwich conveyed on the guide table, air at a predetermined pressure can be jetted to the front end of the inclined surface of the guide table. Although a blower nozzle as a suitable opening means is provided, the present invention is not limited to this. For example, a tongue-shaped elevating body (not shown) is inserted from the opening of the bag body to expand the opening. Further, the opening may be widened by the suction force of a vacuum device (not shown) that can be moved up and down. However, it is needless to say that a structure that injects air is preferable in consideration of cost and workability.

Further, in the above-described embodiment, the film packaging apparatus is prepared by cutting the film piece or the film piece on the other side opposite to the one surface opposite to the surface of the sandwich of the film piece delivered in the hanging state. At least one of the obtained sheet-like film is pressed from the lower side of the surface to the upper side along with the movement of the sandwich, and the film piece or the film piece is cut into the adhesive material exposed on the surface. By using the film abutment, the film abutment plate for bringing the sheet-shaped film into close contact with the film abutment is rotatably supported and hung down, so that it is more beautiful in the previous process of being stored in the bag body, There is a great advantage that the sheet-like film can be firmly adhered to the surface of the sandwich, for example, by blowing air or A film piece or a sheet-like film obtained by cutting the film piece through a plate (not shown) attached to the end of the retractable arm is placed on the surface of the sandwich in a pre-process of being stored in the bag body. The same advantages as described above can be obtained even when they are brought into close contact with each other, but it is needless to say that they are not necessarily required in the present invention.

Further, in the above embodiment, means for transporting the sandwich is not described. For example, a conveyor mechanism is provided on the guide table, or the sandwich slides on the guide table at a constant speed toward the bag body. The configuration may be such that the operator may manually transfer all the sandwiches, and the specific means of transporting the sandwich is not limited in any way.

In essence, the sandwich is transported so that the surface of the sandwich with the various sticky materials or the adhesive seasoning is exposed to the hanging film piece, and then the film piece in contact with the surface Can be obtained by cutting a sheet-like film obtained by cutting a predetermined length onto the surface to cover the surface and then feeding the sandwich into a bag body to obtain a sandwich package. If so, the specific structure, shape, etc. of each part such as the film storage part of the packaging device, the film feeding device, the cutting means of the film piece, the bag holder and the like can be freely changed within the range intended by the present invention.

[0050]

As described above, the present invention provides a method for transferring a sandwich to contact the exposed sandwich surface of various tacky materials or adhesive flavors toward a sagging piece of film, and then transferring the sandwich. A sheet-like film obtained by cutting a piece of film in contact with the surface into a predetermined length is dropped on the surface to cover the surface, and then the sandwich is fed into the bag body for packaging and sandwiched. Can be obtained.

Therefore, in the state where the sheet-like film is placed on the surface of the sandwich on which the various sticky materials and the adhesive seasonings are exposed and stored and packaged in the bag body, even if the respective parts of the bag body are not deformed. Not only when the bag is made of a material that is not easily deformed or when the bag body is made of a material that does not easily deform, It is possible to adhere to the surface of the sandwich in a free state without being restricted by the end of the main body, and to move freely in the bag main body together with the sandwich.

Further, since the sheet-like film freely moves in the bag body together with the sandwich in a free state without being restrained at the end by the bag body, the sheet-like film adhered to the adhesive material or the adhesive flavoring agent. It is possible to reliably prevent the adhesive material and the adhesive seasoning from being rubbed and stained on the inner surface through a moving sandwich.

Therefore, it is possible to reliably prevent the adhesive material or the adhesive seasoning from being rubbed on the inner surface of the film adhered to the adhesive material or the adhesive seasoning via the moving sandwich, and to thereby stain the inner surface. It is extremely excellent that a large amount of good-looking sandwich packaging products with exposed sticky materials and adhesive seasonings sandwiched in order to increase consumer's willingness to purchase can be obtained in large quantities by simple packaging work. It has an effect.
