Description

  The present invention provides a reel-shaped product, in particular, a long sheet slit to an arbitrary width, such as a lead sealant film used for a secondary battery, a metal film for electrodes, a semiconductor tape carrier such as a TAB tape, etc. The present invention relates to a package for packing a reel-shaped product in a state of being wound into a shape, and providing the product for transportation.

  As electronic devices such as mobile phones and notebook computers become thinner and lighter and IC packages become smaller and thinner, films such as sealant films for secondary battery leads, metal films for electrodes, and semiconductor tape carriers such as TAB tape Members are widely used. These film-like members are usually packed and transported in the form of a reel-like product obtained by winding a long body slit in an arbitrary width into a reel.

  As a conventional method for packing reel-shaped products, Japanese Patent Application Laid-Open No. 2004-087858 (Patent Document 1) discloses that when a tape carrier in which a conductor pattern such as a chip mounting portion is formed on a tape-shaped substrate is shipped, the tape carrier is used. A packaging method is disclosed in which a vacuum is drawn in a state of being wound on a reel, followed by drying, enclosing in a packaging bag, and packaging.

  Japanese Patent Laying-Open No. 2005-126142 (Patent Document 2) holds both sides of an electrode member wound around a winding core via a pair of cushion materials and has a side surface larger than the outer shape of the electrode member. There has been disclosed a package comprising a pair of flanges and a packaging film.

  Further, JP 2010-052774 A (Patent Document 3) discloses a TAB tape in which a circuit made of a metal wiring and a solder resist is repeatedly formed on a tape-like insulating film and wound around a core reel for packaging. Regarding the packing method, a TAB tape packing method including a first step of winding a TAB tape around the outer peripheral surface of the core reel and a second step of vacuum-sealing a reel wound with the TAB tape in an antistatic bag is disclosed. ing.

  When packaging these reel-shaped products, it is important to maintain quality during storage and transportation, to prevent dust and foreign matter from being attached due to damage to the packaging film, and to rewind and disengage due to external impact.

JP 2004-087858 A JP 2005-126142 A JP 2010-052774 A

  When transporting reel-shaped products that have been slit and wound into reels, dust or dust generated by friction with the packing material may adhere to the product when it is exposed to the outside air, or winding or misalignment may occur due to vibration or impact. Unwinding may occur. In addition, when transporting multiple reel-shaped products together, if the reel-shaped products are stacked in a packaging box, the products themselves have irregularities, resulting in gaps between the products, and the shape of the products becomes irregular with time due to the weight of the products themselves. It follows that and deformation along this tends to occur. In particular, this tendency is remarkable because the maximum load is applied to the lowermost part of the packaging box. Furthermore, when an external impact is applied from the vertical and horizontal directions, the products in the packaging box move violently due to the impact, and the products may collide with each other and deform. In order to prevent these problems, in the conventional technology, the reel-shaped product is vacuum-packed to prevent the outside air from entering, and measures such as press-contacting the reel shape to prevent deformation are taken. In order to protect the device, a device such as a protective material such as a cushioning material or a pad is inserted between the products.

  In such a conventional technique, a protective material such as a pad is generally used having a size substantially equal to the bottom surface of the packaging box. This is because when the impact is applied to the packaging box, the pad is prevented from moving in the horizontal direction and the pressure in the vertical direction is evenly applied. Using protective materials of such dimensions and shape can be expected to prevent damage and deformation of the packaging box due to impact from the horizontal and vertical directions, but when unpacking the packaging box and taking out the product and pads, There is no gap for lifting the pad with hands or fingers, and it is difficult to remove them. In such a case, it is possible to make notches or holes in several places on the pad and provide a space for inserting hands and fingers, but such means not only weakens the strength of the packaging itself, The pad manufacturing cost also increases. In addition, a method of taking the packing box upside down (unpacking part down) can be considered, but the size of the product and the pad and the cross-sectional area of the packing box are almost the same. It is difficult to separate from the packing box. Even if it can be separated, the product and the pad may collapse, and the product may be deformed.

  The present invention solves these problems of the prior art, and can suppress winding deviation, unwinding, and deformation due to vibration and shock when transporting the reel-shaped product, and the reel-shaped product can be taken out when unpacking. The purpose is to improve convenience.

  That is, the present invention is a packing body for storing a packaging bag containing a reel-shaped product, the reel-shaped product is stored in the packaging bag, and a plurality of packaging bags storing the reel-shaped product are laid in the horizontal direction. It is a reel-shaped product package that is stored in a packaging box in a state in which at least a part of the packaging bag is folded in the vertical direction when stacked individually and stored in the packaging box.

In this invention, a packaging bag shall be equipped with the storage part which accommodates a reel-shaped product inside and is vacuum-sucked and sealed.
Further, it is desirable that the reel-shaped product stored in the packaging bag is stored so as to be positioned at the approximate center of the bottom surface of the packaging box.
Furthermore, it is preferable that the packaging bag has a substantially rectangular shape having long sides and short sides, and the bottom surface of the packaging box has a substantially square shape.

In the present invention, when a plurality of packaging bags containing reel-like products are laid in the horizontal direction and stacked in a vertical direction and stored in a packaging box, the packaging box is partially or entirely between the plurality of packaging bags. A protective material having substantially the same dimensions as the bottom surface of the packaging bag can be inserted, and at least a part of the packaging bag can be bent in the vertical direction between the side surface of the packaging box and the end surface of the protective material to form a protruding portion.
In addition, when a plurality of packaging bags containing reel-like products are stacked in the horizontal direction and stored in the packaging box, at least one of the plurality of packaging bags has substantially the same dimensions as the bottom surface of the packaging box. May be sandwiched from above and below, and at least a part of at least one packaging bag may be bent in the vertical direction along the side surface of the packaging box to form a protruding portion.

  According to the present invention, the reel-shaped product in the packaging bag is pressed and restrained from moving, so that it is easy to pack and take out while preventing winding displacement and unwinding due to vibration and shock during transportation. It becomes possible to improve. In addition, deformation of the reel-shaped product can be suppressed. Furthermore, it becomes possible to take out the reel-like product without damaging it by making it easier to take out the reel-like product and the protective material stored in the packaging bag when unpacking the packaging box.

In this method, the gas inside the packaging bag is removed by suction (vacuum suction) using a suction nozzle, and the packaging bag can be welded and sealed (heat sealed) with a heat sealer in the suction state. Since the reel-like product 10 in the packaging bag is pressed by the vacuum suction process and the movement is restricted, the ease of packing and unloading is improved, and winding displacement and unwinding due to vibration and impact during transportation are prevented. Can do.

Next, the method for packing the reel-shaped product package of the present invention will be described.
4a and 4b are schematic side perspective schematic views of one embodiment of a packing body according to the present invention.
With reference to FIG. 4a, the packaging bag 2 which accommodated the reel-shaped product is accommodated in the packaging box 5 in the state laid down in the horizontal direction. A protective material 4 is inserted between the bottom surface of the packaging box 5 and the packaging bag 2. The bottom surface of the packaging box 5 has a substantially square shape, and the reel-like product stored in the packaging bag 2 is stored so as to be positioned at the approximate center of the bottom surface of the packaging box 5. At this time, at least a part of the package 2 containing the reel-shaped product is bent in the vertical direction along the side surface of the packaging box 5, thereby forming the protruding portion 3.
The packaging box 5 used in the present invention may be a normally used cardboard box or the like, and is not particularly limited, but may be a packaging box made of plastic, cardboard, foamed sheet or the like. As a material of the packaging box 5, corrugated paper (for example, double-sided K5W flute outside the liner) or the like is preferable for absorbing external impact and suppressing deformation of the reel-shaped product.
The wall thickness of the packaging box is preferably 3 mm to 13 mm, more preferably 5 mm to 8 mm. If the wall thickness is too thick, the box plate itself tends to be deformed, such as a dent, and if it is too thin, the strength against external impact is insufficient.

The shape / dimension of the packaging box 5 may be determined by the shape / dimension of the reel-shaped product, but it is a substantially square bottom surface having a length substantially equal to the short side width of the packaging bag 2 for storing the reel-shaped product. If it has, it is preferable when preventing winding slippage and unwinding due to vibration and impact during transportation. In the case of using the packaging box 5 having a substantially rectangular bottom surface having a short side and a long side, the bottom surface may be a substantially rectangular bottom surface having a short side substantially equal to the short side of the packaging bag 2 for storing the reel-shaped product. At this time, the long side of the packaging bag 2 is made longer than the long side of the substantially rectangular bottom surface of the packaging box 5.
When determining the shape and dimensions of the packing box 5 based on the shape and dimensions of the reel-shaped product, for example, when the reel diameter of the reel-shaped product is 200 mm to 400 mm, the inner dimension of the short side of the bottom surface is 250 mm to 450 mm. More preferably, when the reel diameter of the reel-shaped product is 240 mm to 280 mm, the inner dimension of one side of the bottom surface is a substantially square having a size of 300 mm to 340 mm.
On the other hand, the height of the packaging box 5 may be determined according to the number of reel-shaped products stored, but illustratively, the inner dimension of the height of the packaging box may be 250 mm to 450 mm, and more preferably, When the reel diameter of the reel-shaped product is 240 mm to 280 mm, the inner dimension of the height is 300 mm to 340 mm. At this time, the number of reel-shaped products that can be stored is 10 to 60 if the product width is 3 mm to 12 mm.

  Referring to FIG. 4b, when a plurality of packaging bags 2 for storing reel-shaped products are laid in the horizontal direction and stacked in the vertical direction and stored in the packing box 5, a plurality of packaging bags for storing the reel-shaped products. The protective material 4 having substantially the same dimensions as the bottom surface of the packaging box 5 is inserted between the two, and the packaging bag 2 for storing the reel-shaped product is sandwiched from above and below by the protective material 4. Between the side surface of the box 5 and the end surface of the protective material 4, at least a part of the packaging bag for storing the reel-shaped product is bent in the vertical direction to form the protruding portion 3.

The protective material 4 may be a commonly used cardboard or the like, and is not particularly limited, but may be a protective material made of plastic, cardboard, air packing, foamed sheet, or the like. As a material of the protective material 4, corrugated paper (for example, liner double-sided C5B flute) or the like is preferable for absorbing external impact and suppressing deformation of the reel-shaped product.
The shape and dimensions of the protective material may be determined by the shape and dimensions of the reel-shaped product. For example, when the reel diameter of the reel-shaped product is 200 mm to 400 mm, the short side is 250 mm to 450 mm. More preferably, when the reel diameter of the reel-shaped product is 240 mm to 280 mm, one side is a substantially square having a length of 300 mm to 340 mm.
The thickness of the protective material is preferably 1 mm to 13 mm, more preferably 3 mm to 8 mm. If the wall thickness is too thick, the box plate itself tends to be deformed, such as a dent, and if it is too thin, the strength is insufficient.
Reinforcing the strength of the packaging box 5 against external impact by inserting a protective material 4 having substantially the same dimensions as the bottom surface of the packaging box 5 between each of the plurality of packaging bags 2 for storing the reel-like products. Can do.

In the packaging body according to the present invention, when a plurality of packaging bags 2 storing reel-shaped products are stacked in the vertical direction and stored in the packaging box 5 in a state where they are laid in the horizontal direction, at least one of the packaging bags storing reel-shaped products is stored. The portion is bent in the vertical direction to form the protruding portion 3. By using this protrusion 3, it becomes easy to take out the packaging bag 2 for storing the reel-like product and the protective material 4 when unpacking the packaging box 5, and the reel-like product can be taken out without being damaged.
Moreover, since the protrusion part 3 formed by bending a part of the packaging bag 2 for storing the reel-shaped product in the vertical direction is sandwiched between the side surface of the packaging box 5 and the end surface of the protective material 4, it is fixed. The movement is restricted, and it is possible to prevent winding displacement and unwinding due to vibration and impact during transportation.

FIG. 5 is a schematic perspective view of one embodiment of a package according to the present invention.
Referring to FIG. 5, the protective material 4 ′ can be inserted along the side surface of the packaging box 5 in the package of the present invention. As the protective material 4 ′, the same materials as those described above for the protective material 4 can be used.

  As described above, the details of the present invention have been described with reference to the drawings, but needless to say, the shape and dimensions of the packaging bag and the packaging box may be those that can obtain the effects of the present invention, and those skilled in the art will be able to Arbitrary shapes and dimensions can be combined as appropriate. Further, a reinforcing protective material can be further inserted into the side surface of the packaging box, or the gap between the reel-shaped product and the packaging box can be filled with a cushioning material.

  The present invention will be described more specifically with reference to the following examples. However, the present invention is not limited to these examples.

As a reel-shaped product, a sealant film for a secondary battery lead was prepared by winding a long body having a film thickness of 80 μm and a film width of 15 mm around a core of 76.2 mm and a thickness of 6 mm. The reel diameter of this reel-shaped product was 242 mm. As a vacuum packaging bag for storing the reel-shaped product, a bag having a long side of 330 mm and a short side of 280 mm made of a laminated film of polypropylene and nylon was prepared.
Referring to FIG. 6, the length of the long side of the vacuum packaging bag is a, the length of the short side is b, the distance from the opening to the heat seal part is c, and the folding position when stored in the packing box is d. In this case, the reel-shaped product is positioned substantially at the center of the storage portion including the length (ad) side and the length b side. In this example, the length (ad) and the length b were substantially the same length (280 mm).

A reel-shaped product is stored in such a vacuum packaging bag, and a vacuum is stored using a tabletop vacuum packaging machine (V-380G manufactured by Tosei Corporation, vacuum degree 87%, sealing time 3 seconds). The packaging bag was vacuum-sealed and sealed, and the reel-shaped product was stored in the packaging bag.
Next, a packaging box made of corrugated paper having a substantially square bottom surface was prepared. The length of the side of the bottom surface of the packaging box was substantially the same length (280 mm) as the length (ad) or the length b.
The packaging bag containing the reel-shaped product is stored in the packing box in the state of being laid sideways, and at this time, the reel-shaped product is positioned substantially at the center of the bottom of the packing box, and at least a part of the vacuum packaging bag. Is bent in the vertical direction at the folding position d. On the packaging bag containing the reel-shaped product, an approximately square cardboard protective material (pad) having the same dimensions (280 mm) as the bottom of the packaging box is placed, and at least a part of the vacuum packaging bag is folded vertically. The reel-shaped product packages were stacked in the vertical direction so that a protective material (pad) was inserted between each of the packaging bags containing the reel-shaped products so as to form protrusions. Finally, the packaging box was sealed to obtain a packaging body of the present invention.

  Regarding the package of this example, the effects of suppressing winding deviation and unwinding due to vibration and impact during transportation, and deformation, and the effect of improving the ease of taking out the reel-like product during unpacking were confirmed. First, as a simple confirmation, after dropping the packaging body of the example 10 times vertically from a height of 1 m, and checking the reel-shaped product stored in the packaging bag, winding misalignment, unwinding, and deformation occurred. There was nothing I did. Next, when we confirmed the transportation by air transportation and land transportation (about 1,000 km), some of the packaging boxes were damaged, but the reel-shaped products contained in the packaging bags were deformed. No abnormalities were confirmed. In addition, the damaged part of the packaging box was caught by a protective material (pad), and it was difficult for the packaging bag to be removed from the packaging box as it was, but the reel-shaped product could be easily removed by pulling up the protruding part.
