Description

  The present invention relates to a paper cup cleaning device, and more particularly to an air cleaning device.

  Conventionally, paper cups have been used for beverages, such as cold cups and hot cups. Moreover, it is also used as a container for storing solid materials such as popcorn.

  4 and 5, a general paper cup includes a body 11 and a bottom 12, and the body 11 mainly forms a body 13 and curls the upper end outward to curl the top curl. 20, the lower end is folded back inward to form the folded portion 14. Further, the bottom material 12 mainly forms a bottom surface portion 15, and an outer peripheral edge portion is bent downward at a substantially right angle to form a bent portion 16. The body 11 and the bottom 12 are joined by heating and bonding the bent portion 16 between the folded portion 14 of the body and the lower end surface of the body. A joint portion sandwiched and joined with the bent portion 16 is referred to as a yarn bottom portion 22 and is formed with the bottom surface portion 15 as a raised bottom. The paper cup 10 is continuously produced by a paper cup production machine, automatically laminated, formed into a predetermined laminated body, packed in a carton, and commercialized.

  However, foreign matter may adhere to the produced paper cup. For example, when foreign matter such as dust in the environment adheres, or when processing such as forming the folded part of the body, forming the bent part of the bottom material, forming the thread bottom part, etc. There is a case. In order to clean such foreign matter, an air cleaning method of blowing air is generally performed. This was especially done on the inner surface of paper cups.

  FIG. 3 shows an example of a conventional air cleaning apparatus. A spin nozzle 30 for blowing air into the exhaust duct 32 is provided. A part of the exhaust duct 32 is opened below the spin nozzle 30, and the opening 17 of the paper cup 10, that is, the inner surface of the paper cup is arranged in the opening. The spin nozzle 30 spins d while blowing air toward the inner surface of the paper cup to clean the inner surface and the bottom surface portion. The spin nozzle 30 spins around one axis as a fulcrum, and sprays and cleans it uniformly. The blown air a becomes an air flow b as shown in the figure, and is discharged from the discharge port 33 of the exhaust duct 32.

  However, in such a method, cleaning is performed with a constant air pressure while the position of the spin nozzle and the position of the cup are determined, and thus cleaning unevenness may occur due to the inner surface portion. For example, there has been a problem that foreign matter such as a joint between the body and the bottom material is mixed into the product without being removed. In addition, it is necessary to provide an exhaust duct that covers the entire spin nozzle, which causes a problem in terms of equipment.

  Also, the paper cup has a portion that is difficult to remove when foreign matter adheres. FIG. 5 shows an example of a cross-sectional view of a general paper cup 10. On the inner surface 18 of the paper cup, there are portions that are difficult to remove when foreign matter adheres, such as the joint portion 21 between the body and the bottom material, and the outer surface of the paper cup, such as the bottom outer surface 19, particularly in the vicinity of the yarn bottom 22. Since the paper cup is in a state in which the product forms are stacked and packaged, foreign matter on the bottom outer surface of the paper cup may adhere to the inner surface. Therefore, it is necessary to clean the inner surface and the outer bottom surface of the paper cup.

There is a proposal for air-cleaning the outer peripheral surface of a container (Patent Document 1). This is because the vent hole is formed in the mold to which the container is mounted, and the total cross-sectional area of the passage is smaller than the passage cross-sectional area of the discharge passage, and the vent hole is formed as the air in the internal space is sucked by the suction blower. In this method, air flowing into the internal space is sprayed on the outer peripheral surface of the container as a high-speed flow to remove foreign matter.

  However, this method has a problem that only one of the outer peripheral surface and the inner peripheral surface of the container can be cleaned.

  There is a need for an air cleaning apparatus that can efficiently clean the inner surface and the outer bottom surface of a paper cup, and that does not cost much in terms of equipment.
