Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a shrink wrapping device.

[0002]

[Prior Art]

 For example, items such as cassette tapes and ROM cassettes in which programs for computers are stored are stored in a plastic case that can be opened and closed for storage, and to prove that they are unused. For this reason, it was manufactured by hermetically storing the entire circumference of the plastic case with a transparent heat-shrinkable shrink film material, and then heat-shrinking the shrink film to make it adhere to the surface of the case. It is sold in the state where the shrink wrappings are stacked and arranged at the store.

[0003]

[Problems to be solved by the device]

 In the case of the shrink wrapping body with the above configuration, since the film is closely attached to the periphery of the packaged item, the method of displaying a large number at the store is to have a stacked arrangement in which it is vertically stacked as described above. . Then, the surface for displaying the contents faces upward, and the visibility for the purchaser decreases, for example, when the display shelf is located at a high place. In addition, if a diagonally inclined display shelf is used to solve this problem, the packages stacked on top will slide down, and the displayable quantity will be reduced.

Therefore, for example, by enclosing it in a bag made of a transparent film material such as a mechanical pencil or a ballpoint pen in a hermetically sealed manner, and by forming a through hole at the upper end of the bag, a suspended display in a store. It is conceivable to apply a packaging body having a possible structure to the shrink packaging body. However, in the case of a shrink wrap, since the shrink film is in close contact with the case (container body), it is not possible to form a suspending hole for the shrink film. Therefore, if an existing packaging device is used, the shrink wrapping body is secondarily packaged with the bag body having the above-mentioned through hole for hanging. However, this complicates the work process and makes it more practical. In addition to being unusable, it has a problem that it prevents the securing of good visibility, which is one of the merits of the shrink package.

The present invention has been made in view of the above background, and an object of the present invention is to provide a shrink package capable of producing a package that can be suspended and displayed while having the advantages of the shrink package. To provide a device.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, in the shrink wrapping device according to the present invention, a container body having an openable and closable box-like shape for accommodating articles and having a projecting piece with a hole integrally formed at an edge thereof is arranged at predetermined intervals. A transporting device for transporting each of them, a score line forming device for forming a score line extending in a direction orthogonal to the traveling direction with respect to the shrink film in the process of pulling out the strip-shaped shrink film continuously drawn out, and the shrink flap. A device for covering the object to be packaged carried out from the conveying device with a film and for sealing / cutting a predetermined position to manufacture an intermediate package in which the container body is housed in the shrink film, and A heating device is provided which heats the intermediate package to cause the shrink film to shrink and bring the shrink film into close contact with the container body.

[0007]

[Action]

 In the score line forming device, a shrink film having a score line formed at a predetermined portion is used to cover the circumference of the container body of a predetermined shape containing the article, and then the predetermined portion is sealed and cut to form an intermediate portion. A package is manufactured. At this time, the score line formed on the shrunk film is arranged close to the projecting piece integrally formed on the container body. Next, when this intermediate package is heated by using a heating device, the air in the intermediate package escapes to the outside through the score line, and the shrink film shrinks heat and adheres to the periphery of the container body. At this time, the projecting piece projects to the outside through the score line.

[0008]

【Example】

 A preferred embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows an entire shrink wrapping device using horizontal pillow packaging according to an embodiment of the present invention, in which a strip-shaped shrink film 1 is continuously drawn out from its original film 2 to form a plurality of guide rollers 3. It is sent to the bag making apparatus section 4 through. In this example, the bag-making device unit 4 is used for so-called horizontal three-way sealing, and a bag-making device having a substantially U-shaped cross section with front and rear and one side surface opened is used.

Here, in the present invention, the score line forming device 5 is disposed in the middle of the drawing. That is, it has a receiving roller 5a and a cutting blade roller 5b which are arranged so as to face each other with the shrink film 1 sandwiched therebetween, and the outer circumference of the cutting blade roller 5b is, in the axial direction thereof, enlarged as shown in FIG. The cutting edge 5c is formed upright so as to extend. By sandwiching the shrink film 1 between the cutting blade 5c and the receiving roller 5a, a score line 7 extending in the lateral direction is formed at a predetermined position of the shrink film 1.

[0010] Further, from the rear of the bag-making device section 4, the articles 8 to be packaged are sequentially fed at a predetermined interval by a conveyor belt 9 with fingers 9a, which is a conveyor, and the articles 8 to be packaged are formed. When it enters 4, the upper side and the lateral side are covered with the shrink film 1 in a tubular shape.

Here, the article 8 to be packaged in this example will be described. As shown in FIG. 3, it is first formed of box-shaped rectangular plastic, and the ROM cassette as the article to be packaged is housed in the internal space. The container main body 10 is provided, and the container main body 10 can be opened in a spread manner at the central portion thereof. That is, it has a set of a lid 11 and a storage body 12 whose opposite surface sides are open, and the both lid bodies 11 and the storage body 12 are connected on one side in the longitudinal direction and are hinged. A projecting piece 13 that projects upward is provided on the upper end surface of the container body 10, more specifically, on the upper end surface 12a of the container 12. Then, a through hole 14 is formed at a predetermined position of the projecting piece 13.

On the other hand, a pair of upper and lower vertical seal rollers 15 are arranged in front of the bag making apparatus 4 in the traveling direction, whereby both ends of the shrink film, which wraps the article 8 to be packaged in a tubular shape, are covered. The package 8 is heat-sealed vertically on one side surface. An end seal device 16 is arranged in front of the vertical seal roller 15, and the end seal device 16 is mounted on upper and lower rotating shafts 16a and 16a, respectively. When the shrink film 1 containing the article to be packaged 8 passes between them, the tubular shrink film 1 at the front and rear ends of the article to be packaged 8 is clamped by the end sealers 16b and 16b, thereby laterally sealing. At the same time, the intermediate package 18 is manufactured by being cut and separated from the shrink film that covers the adjacent package. Further, in front of the end seal device 16 in the traveling direction, a shrink tunnel 19 which is a heating device for heating the intermediate package 18 is disposed.

Next, the operation of the above embodiment will be described. First, the container body 10 in which the ROM cassette is housed, that is, the article to be packaged 18 is carried on the conveyor belt 9 at predetermined intervals and is sequentially supplied to the bag making apparatus unit 4. On the other hand, the shrink film 1 continuously drawn out is guided to the bag making device section 4 after a predetermined score line 7 is formed by the score line forming device 5 in the middle of drawing out the shrink film 1 and the product to be packaged there. It is formed in a tubular shape so as to wrap around 8. Then, the article 8 to be packaged is transported together with the tubular shrink film 1, and a predetermined portion of the shrink film 1 is sealed and cut by the vertical seal roller 15 and the end seal device 16 during the transport, and the package 8 shown in FIG. The intermediate package 18 having the center seal part 20 and the end seal part 21 as shown in FIG. The cut line 7 is formed at a predetermined portion of the intermediate package 18, and the cut line 7 is formed on the upper end of the projecting piece 13 provided on the container body 10 housed in the intermediate package 18. The position is adjusted so as to be arranged close to the edge 13a.

Next, by passing the intermediate wrapping body 18 having such a configuration through the shrink tunnel 19, the air inside the intermediate wrapping body 18 escapes to the outside through the score line 7, and the shrink film 1 shrinks accordingly. Then, it tries to adhere to the peripheral surface of the container body 10. Along with this contraction, the upper edge 13a of the projecting piece 13 enters the cut line 7, and as the shrink film 1 shrinks, the projecting piece 13 projects to the outside through the cut line 7 and the container body. The shrink film is in close contact with the entire periphery of 10 to manufacture the package 22 as shown in FIG. Then, in the final shape, the score line 7 widens to form the opening 23, and the projecting piece 13 projects outward from the opening 23.

Then, the purchaser of the packaging body 22 can take out the ROM cassette housed in the container body 10 by opening the shrink film 1 that is in close contact with the container body 10. In this example, the opening 23 is torn by inserting a finger or the like into the opening 23 and picking it up, so that the opening can be easily opened.

In the package having such a configuration, since the periphery of the container body that can be opened and closed is tightly wrapped with the shrink film, it can be easily determined whether or not it is in the unused state. That is, the virginity of the product can be guaranteed. Further, when the product is displayed at a store or the like, it can be performed through the through hole 14 formed in the projecting piece 13. Further, since the projecting piece with the hole for hanging is formed on the container body 10 itself, it is not necessary to provide a through hole for hanging on the shrink film itself, and the structure is simple, and the manufacturing process is also simplified.

[0017]

[Effect of the device]

 As described above, in the shrink wrapping device according to the present invention, the container body itself is formed with the projecting piece with a hole, and the container body is wrapped with the shrink film in which the notch line is formed at the predetermined portion to form the intermediate wrapping body. Since it is manufactured, the projecting piece projects to the outside through the cut line at the time of shrinking, so that the shrink film can be closely attached to the container body. That is, it is possible to manufacture a package that can be suspended and displayed while having the advantages of the shrink package.
