Abstract

PURPOSE: A metered waste bag maker and a method for manufacturing the same are provided to prevent the metered waste bag from being forged by confirming the light emission when a BLBL(Black Light Blue Lamp) is lighted on in a process of making the metered waste bag. CONSTITUTION: A metered waste bag maker has an extrusion molding machine(10). The extrusion molding machine consists of a heating cylinder(14) for melting particles or chip type thermoplastic molding material, particularly, polyethylene supplied from a hopper(12) with heat, and a molding frame(16) mounted on a side of the heating cylinder to extrusion-mold the molten polyethylene into a tube type film(52). When mixture is supplied to the molding frame from a nozzle of a mixture injector, the mixture is mixed with the molten polyethylene flowing from the heating cylinder. The polyethylene is extrusion-molded into the tube type film by the molding frame. The tube type film has a string of mixture as the mixture is mixed with the molding material partially. The tube type film is made to a roll type film(56) and then to a metered waste bag. The metered waste bag includes a lengthwise string of mixture. When a BLBL is lighted on toward the metered waste bag having the string of mixture, the light is reflected from the fluorescent string. Therefore, the metered waste bag is prevented from being forged.

Description

Manufacturing method and apparatus thereof of pay-as-you-go garbage bag {METHOD AND APPARATUS FOR MANUFACTURING SPECIFIC COMMERCIAL DUTY TRASH ENVELOPE}

The present invention relates to a method and apparatus for manufacturing a pay-as-you-go garbage bag, in which all or part of the pay-as-you-go garbage bag includes a pigment that emits light to a BLB lamp (Black Light Blue Lamp) to identify whether or not a forgery exists.

In order to reduce the amount of garbage discharged from households, a waste-based system is used to calculate the fee according to the waste discharge. The waste-based waste bag used for the waste-based system includes a collection fee. Therefore, since the price of the pay-as-you-go garbage bag is usually tens of times higher than the manufacturing cost of the general bag, there is a situation in which a person who forges and sells the pay-as-you-go garbage bag to seize the difference between the manufacturing cost and the sale price.

However, it is difficult to make a special mark to prevent counterfeiting because the pay-as-you-go garbage bags made of polyethylene material are relatively thin, and the marks printed on the pay-as-you-go garbage bags can be easily reproduced without distinguishing genuine and counterfeit goods. There was.

In light of such a problem, the present applicant proposed a technique for manufacturing a pay-as-you-go garbage bag marked with a counterfeit prevention mark by stamping a non-forgery mark on the film for a pay-as-you-go garbage bag in Korean Utility Model Registration No. 167043. This technology has the advantage that traders and consumers can easily identify the counterfeit through secrets, but the manufacturing process of pay-as-you-go garbage bags has become complicated.

In addition, the applicant's Korean Utility Model Registration No. 172606 prints part or all of the pay-as-you-go garbage bag with ink that contains pigments that emit light on the BLB lamps. At that time, a technique is disclosed in which the part is illuminated to identify the forged envelope. However, the portion where the pigment is mixed with the ink and printed has a problem that the printing state is not clear and easy to be erased.

The present invention is to solve the problems of the prior art as described above, an object of the present invention is to determine whether the light emission when the BLB lamp is irradiated in the manufacturing process of the pay-as-you-go garbage bag to prevent counterfeiting The present invention provides a method for manufacturing a bag and an apparatus thereof.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, a method of manufacturing a pay-as-you-go garbage bag according to the present invention and a preferred embodiment of the apparatus will be described in detail with reference to the accompanying drawings.

1 to 5 is a view showing for explaining the manufacturing method and apparatus of the pay-as-you-go garbage bags according to the present invention.

First, referring to FIG. 1, an apparatus for manufacturing pay-as-you-go garbage bags according to the present invention includes an extrusion molding machine 10. The extrusion molding machine 10 includes a heating cylinder 14 for melting and supplying a thermoplastic molding material 40 in the form of granules or chips, for example, polyethylene, by heating from the hopper 12, and the heating cylinder. It is composed of a forming mold 16 installed on one side of 14 to extrudable the flowable molding raw material supplied from the heating cylinder 14, that is, the polyethylene in the molten state into the tubular film 52.

In addition, a blower 18 is formed on the upper part of the mold 16 to inject a constant pressure of air into the center of the tubular film 52 extruded by the mold 16 to maintain the shape of the tubular film 52. Is installed. That is, the tubular film 52 is expanded by the constant pressure of air injected from the blower 18 to maintain the expanded tube shape. The upper surface of the mold 16 is provided with an annular air nozzle 20 connected to the blower 18, the air nozzle 20 is injected into the air around the tubular film 52 to form a tubular film 52 Cool. And the guider 22 which guides the tubular film 52 to be folded by the sheet-like film 54 is provided above the shaping | molding die 16. The guider 22 is formed such that the space 26 formed between the two plates 24 is gradually narrowed from the lower part to the upper part. Therefore, the tubular film 52 passing through the space 26 of the guider 22 is folded into the sheet-like film 54 as it goes upward.

Apparatus for producing a pay-as-you-go garbage bag according to the present invention includes a press rolling device 28 for closely contacting the sheet-like film 54 passing through the guider 22, and a sheet-like film 54 for passing the press rolling device 28. The first feed rolling device 30 and the second feed rolling device 32 are provided. The sheet-like film 54 passing through the first and second feed rolling devices 30 and 32 is wound by the winding machine 34 into the roll-like film 56.

On the other hand, the rolled film 56 is made of a single payload garbage bag 60 as shown in FIG. 2 by a sealing device and a cutting device which are separated from the winding machine 34 and subsequently. Since the sealing device and the cutting device of the pay-as-you-go garbage bag 60 are general, detailed description thereof will be omitted. The inlet 62 is formed at one end of the pay-as-you-go garbage bag 60 after the manufacturing process of the sealing device and the cutting device, and the sealing line 64 is formed at the other end by sealing of the sealing device.

1 and 2, according to a characteristic embodiment of the present invention, the hopper 12 of the extrusion molding machine 10 emits fluorescence when the light of the BLB lamp 70 is irradiated together with the thermoplastic molding material 50. A predetermined amount of the light-emitting pigment 80, for example, an optical brighter is added. In the present invention, the BLB lamp 70 refers to a lamp that generates light having a peak of 365 nm in the wavelength range of 315 to 380 nm. When the optical brightener emits light at its own wavelength when the light of the BLB lamp 70 is irradiated, the optical brightener may give a discriminating power to people.

The optical brightener is preferably mixed in an amount of about 0.0005 to 0.1% by weight with respect to the thermoplastic molding material 50, and more preferably in an amount of about 0.005% by weight. The reason is that when the optical brightener is mixed in an amount of 0.0005% by weight or less with respect to the thermoplastic molding material 50, when the light of the BLB lamp 70 is irradiated, the light emission of fluorescence is difficult to obtain, and the amount is not less than 0.1% by weight. This is because when the optical brightener is mixed, only the same effects as those mixed in an amount of 0.1% by weight can be obtained, while the amount of the optical brightener is used more than necessary to increase the manufacturing cost.

On the other hand, when the thermoplastic molding material 50 and the pigment 80 are put together in the hopper 12 of the extrusion molding machine 10, the thermoplastic molding material 50 and the pigment 80 are melted by the heating cylinder 14 After the mixing, the mold is fed to the mold 16 and manufactured into a roll-shaped film 56 by a series of manufacturing processes described above.

Therefore, the pigment 80 is entirely contained in the pay-as-you-go garbage bag 60 of the present invention produced by the roll-type film 56 containing the pigment 80. As such, when the light of the BLB lamp 70 is irradiated to the pay-as-you-go garbage bag 60 containing the pigment 80, as shown in FIG. 2, the fluorescence is emitted. It is easy to see.

When the flowable mixture 82 is supplied from the nozzle 42 of the mixture injector 40 to the forming mold 16, the mixture 82 is mixed with the flowable molding material supplied from the heating cylinder 14 and formed. The die 16 is extruded into the tubular film 52. At this time, since the flowable mixture 82 injected through the nozzle 42 of the mixture injector 40 is partially mixed with the flowable molding material, the flowable mixture 82 is mixed with the tubular film 52 in a single line. The tubular film 52 is made into the rolled film 56 through the same manufacturing process as described in FIG. 1, and then made into a pay-as-you-go garbage bag 60.

Therefore, in the pay-as-you-go garbage bag 60 of the present invention, the mixture 82 is included in one line along the longitudinal direction.
