Abstract

PROBLEM TO BE SOLVED: To make occurrence of loss in thread difficult even if packaged cheeses are cased in contact with one another by tightly coating at least the outer periphery of a cheese comprising a bobbin thread wound with a heat- shrunk film. SOLUTION: At least an outer periphery, preferably both end faces, of a cheese 1 comprising a thread 3 wound around a bobbin 2 is tightly coated with a heat-shrinkable film 10 which has been shrunk by heat. As the heat- shrinkable film 10, heat-shrinkable polyethylene, a polyolefin film such as polypropylene, a polyester film, a polyvinyl chloride film, a polyvinylidene chloride film or the like may be used, although a uniaxially stretched film is typically used. In this case, the uniaxially stretched heat-shrinkable film 10 preferably coats the cheese 1 so that its heat-shrinking direction is along the peripheral direction of the bobbin 2, that is a wound direction of the thread 3 to be heat-shrunk.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging method for cheese formed by winding a thread around a bobbin, and a packaging cheese obtained by the method.

[0002]

2. Description of the Related Art
When transporting cheese, the cheese thread becomes dirty as it is,
Because of the occurrence of scratches and thread breakage, packaging is performed. In this case, as a packaging method, a method of wrapping cheese with cellophane paper, haptron paper, or rayon cake net paper, or crossing with a rubber band is used.

[0003] However, in the case of paper packaging, it is necessary to wrap the cheese in paper one by one, so that
It requires a great deal of labor, is very troublesome, has a risk of tearing the paper, does not deal with broken yarn, and often generates a lossy yarn. In addition, the method of crossing the rubber band is not sufficient in that the cheese thread is exposed to the outside as it is, which is not sufficient in terms of dirt and damage of the cheese thread. To prevent this, it is necessary to further wrap the above paper. There is.

[0004] In particular, in the above-mentioned packaging method, when a large number of cheeses packaged as described above are housed in a box and transported, the packaged cheeses are brought into contact with each other and packed in a box.
Since the wrapping paper is not in close contact with the cheese, there is a problem in that the yarn wrapping the paper wrapping the cheese with the cheese yarn may cause a loss thread or break the paper due to vibration during transportation.
For this reason, packaged cheeses are packed in boxes so as not to contact each other. In order to pack the packed cheeses apart from each other and pack them in a box, it is necessary to individually support the packed cheeses. For example, a support plate as shown in FIG. 2 is also used. That is, in FIG. 2, reference numeral 1 denotes a cheese formed by winding a thread 3 around a bobbin 2 (note that the cheese 1 is wrapped with wrapping paper, but the wrapping paper is not shown in FIG. 2). ), This packaged cheese is placed in a bobbin 2 in a cardboard box.
The upper and lower ends are supported by being inserted into recesses or holes 5 provided in the support plate 4, and thus a large number of packaged cheeses are supported by the support plate 4 in a multi-tiered manner to cut balls. Housed in a box.

[0005] Therefore, in the above-mentioned packaging method, since the packaging is not sufficient to protect the cheese thread, each packed cheese must be accommodated in a box when packed and transported in this way, and the waste is not contained in the box. This increases the space required, the size of the box, the cost of packing and transportation, and the risk of collapse.

SUMMARY OF THE INVENTION The present invention has been made to improve the above circumstances, and it is possible to reliably protect and package cheese, and even if the packaged cheeses are packed in a box in a state where they are in contact with each other, it is difficult to generate a loss yarn. Another object of the present invention is to provide a packaged cheese and a method for packing the cheese, which are highly economical.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a packaged cheese in which at least an outer peripheral portion of a cheese formed by winding a yarn around a bobbin is tightly covered with a heat-shrinkable film, and a bobbin. The present invention provides a cheese packaging method in which at least the outer peripheral portion of a cheese formed by winding a yarn is covered with a heat-shrinkable film, and then the heat-shrinkable film is heat-shrinked to bring the film into close contact with the cheese outer peripheral portion.

In this case, as the heat-shrinkable film, a uniaxially-drawn polyolefin, polyester or polyvinyl chloride film is preferably used, and the heat-shrink direction is substantially matched with the winding direction of the yarn. It is preferable to perform heat shrinkage and close packaging as described above.

According to the present invention, since the cheese is tightly coated on the heat-shrinkable film by heat shrinkage of the film,
The cheese yarn is reliably protected, dirt and damage are prevented, and yarn breakage is reliably prevented. Therefore, there is no loss yarn, and the use yield of yarn is improved. In addition, since the cheese is securely protected by the heat-shrinkable film and the film is closely adhered to the outer peripheral portion of the cheese, when packing the cheese in a boxed state, vibration occurs during transportation or the like. , Even if the wrapped cheese rubs each other,
Since damage to the yarn and breakage of the yarn are prevented, a large number of packaged cheeses can be brought into contact with each other and packed in a box. Therefore, the above-mentioned support plate is not required, the box packing can be simplified, and the packing can be performed at a higher density than before. Boxes can be packed without creating a large space, and the same number of packaged cheeses can be accommodated in a small volume box or in a box of the same volume. Therefore, the number of packing members is reduced, and the packing cost and the transportation cost are reduced. In addition, the method of packaging cheese by heat shrinking using the heat shrinkable film is easy, and the heat shrinking step can be automated.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail.
As shown in, at least the outer peripheral portion of the cheese 1 formed by winding the yarn 3 around the bobbin 2, and preferably both end portions of the cheese 1 are adhered and covered in a state where the heat-shrinkable film 10 is thermally contracted. Things.

Here, the material and shape of the bobbin 2 may be publicly known. Further, the yarn 3 wound around the bobbin 2 may be any of a raw yarn, a twisted yarn, and a spun yarn, and may be a natural fiber, a synthetic fiber, or the like.

Further, as the heat-shrinkable film 10, a known film can be used, and heat-shrinkable polyethylene,
Polyolefin films such as polypropylene, polyester films, polyvinyl chloride films, polyvinylidene chloride films and the like are used, and usually uniaxially stretched films are used. In this case, it is preferable that these uniaxially stretched heat-shrinkable films cover the cheese 1 so that the heat-shrinkage direction is along the circumferential direction of the bobbin 2, that is, the winding direction of the yarn 3, and heat-shrink the film. Yarn breakage may occur during heat shrinkage.

The method of coating the cheese with a heat-shrinkable film will be described in more detail. As described above, the heat-shrinkable film is surrounded by the heat-shrinkable direction of the bobbin in a circumferential direction, and if necessary, is adhered. The surrounding end is fixed with a tape or the like, and then heated to shrink the film by heat. The heating temperature is selected according to the type of the heat-shrinkable film, but is usually about 50 to 100 ° C., and the heating time is sufficient if the heat-shrinkable film is sufficiently heat-shrinked and the film adheres to the cheese, It can be several seconds to several minutes. In this case, a steam set is performed on the twisted yarn or the like, but the heat shrinkage can be performed simultaneously with the steam setting in the twisting step. Then, it is introduced into a steam introduction constant temperature bath, and heat shrinkage can be performed simultaneously with the steam setting. This steam set is usually 5
It is performed at 0 to 100 ° C for about 20 to 60 minutes,
The heat shrinkage of the heat shrinkable film is promptly completed, and then steam setting is performed in a state where the cheese adheres to and is covered with the heat shrunk film.

Next, an experimental example will be described. [Experimental example] A uniaxially stretched polyethylene terephthalate film (170 mm x 700 mm, thickness 30 µm, manufactured by Mitsubishi Plastics, Inc.) was wound around a bobbin with twisted yarn wound around the bobbin with the heat shrink direction of the film aligned with the circumferential direction of the bobbin. After the surrounding end was fixed with an adhesive tape, it was put into a steam setting device and steam set at 80 ° C. for 40 minutes.

In the obtained cheese, the above film was thermally shrunk and adhered to and covered the bobbin. Next, the eight packaged cheeses were put in a box in contact with each other, vibrated for a long time, then the packaged cheese was taken out, and the film was broken to examine the appearance of the cheese. Was.

[0016]

According to the present invention, the cheese can be reliably protected and packaged, and there is no problem even if the packaged cheese is packed in contact with each other at the time of transportation, and the packaging cost and the transportation cost can be reduced. it can.
