Definitions

  • This invention generally relates to a cap applying apparatus. More particularly, the present invention relates to an apparatus for applying a cap body to a packaging container.
  • Brick-shaped packaging containers for holding liquid food products such as milk, carbonated drinks and the like are provided with a cap body that is adapted to be opened and closed as required so that the liquid food product can be repeatedly poured out and dispensed from the container.
  • the cap body is usually applied to the top portion of the packaging container by a hot melt process, a heat sealing process, an ultrasonic sealing process or other similar techniques.
  • ultrasonic waves are applied to the cap body while pressing the cap body against the portion of the packaging container where the cap body is to be applied. As a result, the surface film of the packaging container is melted and the cap body is secured to packaging container.
  • a need exists for an improved cap body applying apparatus that is capable of applying the cap body to the packaging container in a relatively simple manner, with a high processing speed, and while maintaining sufficient strength at the cap body/packaging container interface.
  • US 2,551,476 describes a transfer means for thermoplastics caps having means to heat said caps during transfer.
  • a heating chamber is provided along the route of transport of the cap in which the cap is heated by an electrical resistance element until a thermoplastic adhesive on the cap becomes soft and tacky.
  • the present invention provides a cap body applying apparatus for applying a cap body to a packaging container.
  • the cap body applying apparatus includes a gas supplying device for supplying hydrogen-oxygen gas mixture obtained by electrolyzing water, a burner unit for receiving and burning the hydrogen-oxygen gas mixture, and a pickup apparatus for transporting a cap body to a heating position above the burner unit.
  • the above burner unit also includes a plurality of nozzles arranged in a pattern corresponding to the underside periphery of the cap body.
  • the cap applying apparatus of the invention can further include a shield plate selectively disposed over each of the nozzles, and an igniter disposed adjacent one of the nozzles.
  • a CCD camera can also be provided for monitoring the flames of the nozzles.
  • an apparatus for supplying and applying cap bodies to a packaging container includes a gas generator for supplying a hydrogen-oxygen gas mixture, and a burner unit connected to the gas generator for receiving the hydrogen-oxygen gas mixture.
  • the burner unit includes a plurality of nozzles from which the hydrogen-oxygen gas mixture is emitted.
  • An igniter is provided for igniting the hydrogen-oxygen gas mixture emitted from at least one of the nozzles to produce a flame at the tip of the nozzle.
  • the apparatus also includes a transport device and a pickup apparatus mounted on the transport device for holding a cap body.
  • the pickup apparatus is transported by the transport device to a heating position above the burner unit to permit the underside surface of the cap body to be heated by the flame emitted from the nozzles and is further transported from the heating position to an applying position at which the cap body is applied to a packaging container.
  • a packaging container holder holds a packaging container to which is to be applied the cap body.
  • Another aspect of the invention involves a process for applying a cap body to a packaging container.
  • the process includes positioning a cap body adjacent a burner unit that includes at least one nozzle that emits a flame, and heating the underside surface of the cap body with the flame that is emitted from the nozzle of the burner unit.
  • the cap body with the heated underside surface is then applied to a packaging container to secure the cap body in position on the packaging container.
  • the cap body applying apparatus of the present invention includes a gas generator 11 for generating a hydrogen-oxygen mixture possessing a 2:1 mixture ratio by electrolyzing water, a tank 12 for holding water, and a water replenishing device 13 for replenishing water to the gas generator 11.
  • the gas generator 11 constitutes the gas supplying device for supplying hydrogen-oxygen gas mixture.
  • the gas generator 11 is comprised of a plurality of cells and is capable of generating, for example, 100 liters of hydrogen-oxygen mixture when a DC current of 15 A is applied for one hour. Generally speaking, the generator breaks down water by electrolysis into its basic elements of two parts hydrogen and one part oxygen. The generator automatically mixes the hydrogen and oxygen to the optimal combustion ratio of 2:1.
  • the hydrogen-oxygen mixture generated by the gas generator 11 is supplied through a filter 14 to a booster 15.
  • the filter 14 is designed to clean the gas produced by the generator to remove aerosols, mists, etc. produced during the electrolysis of water.
  • the booster 15 consists of one or more tanks which hold methanol.
  • the pure hydrogen-oxygen mixture gas mixture flows into the booster where it is enriched with combustible alcohol vapor.
  • a hydrogen-oxygen gas mixture rich in methanol gas can be produced by injecting the hydrogen-oxygen gas mixture at the bottom of the booster tank(s).
  • the flame temperature is approximately 3200° C.
  • the methanol gas-rich hydrogen-oxygen gas mixture although the flame temperature is low at 2500 degrees C, the amount of energy the flame has increases. That is, the combustion of the hydrogen together with the alcohol (methanol) lowers the flame temperature to between about 2500° C and about 2700° C while at the same time increasing or boosting the energy content of the flame.
  • the apparatus of the present invention also includes a tank 16 for holding methanol, and a replenishing device 17 for replenishing methanol to the booster 15. While methanol is used in this embodiment, other kinds of alcohol may be used in place of methanol.
  • the hydrogen-oxygen gas mixture is sent through a reverse flame check device 20 and a switching valve 21 to a burner unit 22.
  • the reverse flame check device 20 is comprised of a cup-shaped filter 25 that is pressed by a spring 26 against an 0-ring 27 so that the flame of the burner unit 22 is prevented from reversing.
  • the switching valve 21 is positionable in two positions. In a first position, the switching valve 21 interconnects the lines L1 and L2, and in a second position, the switching valve 21 interconnects the lines L2 and L3. In the first position, the hydrogen-oxygen gas mixture from the booster 15 is supplied to the burner unit 22 for burning. In the second position, air from an air supply device is supplied to the burner unit 22 for extinguishing.
  • the burner unit 22 comprises a group or array of nozzles 31, with each nozzle 31 being provided with an opening from which hydrogen-oxygen gas mixture is ejected to create a tiny flame. As a result, a group or array of tiny flames is created.
  • An igniter 32 is disposed adjacent one of the nozzles 31 of the nozzle group to ignite all the nozzles 31.
  • a flame monitor camera 33 is disposed obliquely above the burner unit 22. At a position obliquely above the burner unit 22 is also disposed a gas detector 34 for detecting gas leakage and troubles or problems in the burner unit 22.
  • a controller 35 is also provided for overall control of the gas generator 11, the tanks 12, 16, and the burner unit 22.
  • the controller 35 starts the cap body applying apparatus automatically without requiring intervention by an operator.
  • the controller 35 also controls the gas generation rate, the amount of hydrogen-oxygen gas mixture that is consumed, and the voltage applied to the gas generator 11.
  • the system is designed so that the monitoring results of the flame monitor camera 33 and the detection results of the gas detector 34 are sent to the controller 35.
  • the cap body 51 that is to be to be applied to the packaging container through use of the apparatus of the present invention is illustrated in FIGS. 2 and 3 .
  • the cap body 51 is integrally formed from a resin material such as polyethylene and includes a main part 50 having a generally U-shaped configuration, a pull-tab 52 supported on the main part 50 for turning or pivoting movement about a hinge 54, and a piercing flap 53 also supported on the main part 50 for interlocked turning with the pull-tab 52 about the hinge 54.
  • the main part also includes a pull-tab holding portion 50a.
  • a detent 50b is formed on the pull-tab holding portion 50a of the main part 50 at a position adjacent the pull tab 52. In this way, the pull-tab 52 is held with the main part 50 by the engagement of the side edge of the pull-tab 52 with the detent 50b. Additional details associated with the construction of the cap body, which details are not necessary for an understanding of the present invention, are described in Japanese Laid-Open Patent Application No. Hei-8-132855 , the disclosure of which is incorporated herein by reference. It is also possible to use the apparatus of the present invention to apply to a packaging container a cap body having a different configuration and construction than that shown in FIGS. 2 and 3 .
  • a pickup apparatus which is described below in more detail, is provided for picking up the cap body and subsequently assisting in applying the cap body 51 to the portion of the packaging container to which the cap body is to be applied.
  • This pickup apparatus carries the cap body 51 to a position directly above the burner unit 22 as shown in FIG. 3 , and the burner unit 22 then heats the underside periphery of the cap body 51 for a specified period of time.
  • the pickup apparatus then carries the cap body 51 to a position where the cap body 51 is pressed against the portion-of the packaging container where the cap body is to be applied.
  • the melted polyethylene resin on the underside periphery of the cap body 51 is joined to the polyethylene resin forming the outermost layer on the packaging container surface.
  • the cap body 51 is applied to the desired region of the packaging container.
  • the periphery of the cap body 51 is melted within a very short period of time. This increases the processing speed of the cap body applying apparatus. Further, the cost of the cap body applying apparatus can be reduced because a special heating apparatus is not required.
  • the various details associated with the burner unit 22 can be seen with reference to FIGS. 4, 5 and 6 .
  • the burner unit 22 includes a burner block 41, a plurality of nozzle securing holes 43 formed in the burner block 41, and a plurality of nozzles 31 adapted to be secured in the nozzle securing holes 43 by way of seal members 45.
  • the nozzles 31 are preferably made of a material having a low heat conductivity.
  • the nozzle securing holes 43 are arranged in a generally U-shaped pattern that generally corresponds in shape to the shape of the underside periphery of the cap body 51.
  • the nozzles 31 which are secured in the nozzle securing holes 43 are thus also arranged in a generally U-shaped pattern.
  • the nozzle holding holes 43 are arranged in two rows in the portions of the array of holes 43 designated P1 and P2. These portions. P1, P2 correspond in location to the pull-tab holding portion 50a of the cap body 51.
  • Each nozzle 31 is constructed as a relatively long pipe of small diameter to create a tiny flame at the tip of each nozzle 31. Since hydrogen-oxygen gas mixture is used as the fuel, the tiny flame created at the tip of each nozzle 31 is stabilized.
  • the nozzle holding holes 43 and the nozzles 31 are arranged so that a portion of the arrangement is devoid of holes and nozzles.
  • This portion of the hole and nozzle arrangement that is devoid of holes and nozzles corresponds in location to the hinge 54 of the cap body.
  • the hinge 54 of the cap body 51 is prevented from being heated and deformed and so the hinge 54 is not inadvertently or accidentally heated by mistake.
  • the operation of the hinge 54 on the cap body is not adversely affected.
  • the melting of the cap body can be uniform along the cap body periphery.
  • the cap body 51 is applied securely to the portion of the packaging container where the cap body 51 is to be applied.
  • the process of the present invention results in a high strength connection at the cap body/packaging container interface after the application of the cap body to the packaging container.
  • the nozzles are relatively long in length and so the tip of each nozzle 31 is spaced sufficiently far from the surface of the burner block 41.
  • This feature coupled with the nozzles 31 being made of a material having a low heat conductivity advantageously prevents the heat of the flame from being transmitted to the burner block 41.
  • the nozzles 31 are arranged at constant or generally intervals in a generally U-shaped pattern, all the nozzles 31 are not ignited at the same time with the igniter 32.
  • FIGS. 7-9 illustrate the manner in which the nozzles 31 are ignited during operation of the apparatus of the present invention.
  • the igniter 32 is activated while the hydrogen-oxygen gas mixture is ejected from all the nozzles 31, only the nozzle 31 (or perhaps several nozzles 31) that is located closest to and immediately adjacent the igniter 32 is ignited as shown in FIG. 8 and the rest of the nozzles 31 are not ignited.
  • a shield plate 57 is employed. This shield plate 57 is placed above the nozzles 31 after the nozzle(s) 31 immediately adjacent the igniter 32 is ignited.
  • the hydrogen-oxygen gas mixture ejected from the nozzles 31 which are not ignited tends to rise, the mixture is prevented from rising by the shield plate 57 and instead is deflected to spread laterally along with the lateral air flow produced at this time.
  • the rest of the nozzles 31 are also subsequently ignited by virtue of the deflected hydrogen-oxygen gas mixture.
  • the shield plate 57 includes two shield portions 57a, 57b.
  • the shield plate 57 is rotatably supported on a shaft 58 for rotation in the direction of the arrow.
  • the shaft 58 is connected to driving device which rotatably drives the shield plate 57 in an intermittent manner so that the shield portions 57a, 57b shield the nozzles 31 from above. More specifically, the shield plate 57 is rotated to shield the nozzles 31 from above after the igniter 31 is activated.
  • the nozzle plate 51 positioned above the nozzles advantageously makes it possible to ignite all of the nozzles 31 with a single igniter 32.
  • the present invention employs the flame monitor camera 33 shown in FIG. 1 to monitor the flames.
  • FIG. 11 illustrates the way in which the flame monitor camera is positioned 33 in the apparatus of the present invention.
  • the flame monitor camera 33 is a CCD camera which recognizes the condition of a plurality of flames as visual data which are analyzed with an analyzing device associated with the controller 35 shown in FIG. 1 to monitor and determine the hue, chroma, and brightness of the flames.
  • a visor 61 can be placed behind the burner unit 22 as shown in FIG. 11 . Further, the burner block 41 can be painted black.
  • FIG. 12 illustrates in plan view the cap body applying apparatus of the present invention during operation while FIG. 13 sets forth a cap applying process time chart depicting the timing of various operations performed during the cap applying process. As seen with reference to FIG. 12
