Definitions

  • the present invention relates to a packaging apparatus, a measuring and packaging apparatus, and a method for producing a package of a granular object having adsorption ability, and, more particularly, to a packaging apparatus, a measuring and packaging apparatus, and a method for producing a package of a granular object by which the residual air in the package can be reduced.
  • a granular object having adsorption ability such as spherical adsorptive carbon contains a large amount of air, and the amount of air varies tremendously depending on temperature. Therefore, when air is emitted from the granular object with an increase in temperature after packaging, the package is swollen and cause problems during encasement, storage, transportation and so on. Especially, since spherical adsorptive carbon has a granule shape close on a perfect sphere, it has high fluidity. Thus, when air remains in the package, spherical adsorptive carbon granules move in the package. After that, when the air in the package disappears with a decrease in temperature of the package, the package is shrunk. Then, when the package being shrunk is torn to open, the spherical adsorptive carbon granules spill out of the package.

  • the amount of residual air in the packages can be made small. Since the amount of residual air in the packages is small, the packages are not swollen after sealing.
  • adsorption ability means to have an ability to retain gas such as air therein like spherical adsorptive carbon or activated carbon.
  • storage bags means bags for containing a granular object. The bags may be separated individually or a plurality of bags may be joined together.

  • the packaging apparatus according to the present invention is, as shown in FIG. 1 for example, any one of the above packaging apparatuses 100, wherein the air removing device 50 may pinch the storage bag 90, into which the granular object has been charged, to expel air from the storage bag 90.
  • the packaging apparatus according to the present invention is any one of the above packaging apparatuses 100, wherein the granular object having adsorption ability may be spherical adsorptive carbon.
  • the packaging apparatus according to the present invention is, as shown in FIG. 2 for example, any one of the above packaging apparatuses, which may further comprise a heating device 12 for heating the granular object before the storage bag 90 is sealed.
  • a packaging apparatus comprises, as shown in FIG. 1 for example: a sealing device 40 for sealing a tube 90 transversely at a first position; a charging device 30 for charging a granular object into the tube 90 sealed at the first position; and a pinching device 50 for pinching the tube into which the granular object has been charged; wherein the tube 90 is sealed transversely at a second position opposite the first position with respect to the pinched part; and wherein the sealing device 40 is actuated with a slight delay after the pinching device 50 has been actuated.
  • the tube into which the granular object has been charged is pinched to expel air therefrom before being sealed, the produced package contains only a small amount of residual air.
  • the packaging apparatus according to the present invention is, as shown in FIG. 1 for example, the packaging apparatus 100 as described above, which may further comprises: a first driving mechanism 52 for driving the pinching device 50; a second driving mechanism 42 different from the first driving mechanism 52 for driving the sealing device 40 ; and a control unit 46 for controlling the driving of the first driving mechanism 52 and the second driving mechanism 42.
  • both the devices can be actuated at appropriate timing.
  • the packaging apparatus according to the present invention is, as shown in FIG. 1 for example, any one of the above packaging apparatuses 100, wherein the face for pinching the tube 90 is elastic and of a shape corresponding to the shape of tube 90 containing the granular object.

Therefore, there is provided a packaging apparatus and a measuring and packaging apparatus for a granular object which can reduce the amount of residual air in the packages to prevent expansion of the packages with an increase in temperature after sealing. Since expansion of the package with an increase in temperature can be prevented, the package can be easily handled during encasement, storage, and distribution, including transport. In addition, the granular object does not spill out of the package when it is opened.
  • a separately packaging apparatus 100 for spherical adsorptive carbon as a packaging apparatus according to a first embodiment of the present invention is first described with reference to the schematic view of FIG. 1.
  • the separately packaging apparatus 100 has a charging device 30, a sealing device 40 and a pinching device 50 as an air removing device.
  • the charging device 30 has a chute pipe 31.
  • the chute pipe 31 has the shape of a funnel with a wide opening at the top so that it can receive spherical adsorptive carbon measured in an amount to be packaged separately from a measuring or metering device (not shown).
  • the lower part of the chute pipe 31 is in the form of a thin pipe so that the spherical adsorptive carbon can be fed into a tube 90.
  • the lower end of the chute pipe 31 is opened. The spherical adsorptive carbon falls through the chute pipe 31 by gravity.
  • the sealing device 40 is disposed below the lower end of the chute pipe 31.
  • the sealing device 40 has top seal bars 41 for heat-sealing the tube 90.
  • the top seal bars 41 which are two metal blocks with flat ends, are heated by a heater and pinch the tube 90 from both sides to heat-seal the tube 90.
  • the timing at which the top seal bars 41 pinch the tube 90 is controlled by a sequencer 46 as a control unit.
  • a signal from the sequencer 46 is transmitted to a sealing device driving mechanism 42 through a cable.
  • the sealing device driving mechanism 42 uses the signal to move the two top seal bars 41 toward each other until they press against each other.
  • the top seal bars 41 can move up and down by a distance equal to the length of individual packets.
  • the pinching device 50 is disposed right below the sealing device 40.
  • the pinching device 50 has two air expel guides 51 for pinching the tube 90 containing spherical adsorptive carbon and a pinching device driving mechanism 52.
  • the two air expel guides 51 are paired with each other.
  • the faces of the air expel guides 51 for pinching the tube 90 are formed by elastic bodies 51a.
  • the elastic bodies 51a are made of rubber or sponge.
  • the elastic bodies 51a may be made of another elastic object such as a synthetic resin.
  • the entire air expel guides 51 may be made of a metal such as a stainless steel without the elastic bodies 51a. In this case, elastic deformation of the pinching faces cannot be expected but the air expel guides 51 have high durability.
  • Each of the tube pinching faces of the air expel guides 51 has a bulged upper portion and a recessed lower portion.
  • the timing at which the air expel guides 51 pinch the tube 90 is controlled by the sequencer 46.
  • a signal from the sequencer 46 is transmitted to the pinching device driving mechanism 52 through a cable.
  • the pinching device driving mechanism 52 uses the signal to move the two air expel guides 52 toward each other until their upper portions press against each other.
  • the air expel guides 51 also can move up and down together with the top seal bars 41.
  • the tube 90 is produced by forming a flat tape into a tubular shape around the lower end of the chute pipe 31 and heat sealing the overlapped portions thereof.
  • the tube 90 is sealed transversely at a prescribed position by the sealing device 40 as described later.
  • the tube 90 is formed into a bag shape having a sealed bottom and an open end and placed with its opening facing the lower opening of the chute pipe 31.
  • the storage bags for the spherical adsorptive carbon are preferably produced from the tube 90 since the storage bags can be supplied continuously.
  • the storage bags are not necessarily joined as a tube but may be separated individually, though.
  • the storage bags may be in the shape of a circular cylinder, quadratic prism, tetrahedron, or hemisphere.
  • the spherical adsorptive carbon measured by a measuring device is poured into the bag-shaped part of the tube 90 through the chute pipe 31 and is heaped up in the lower part of the bag-shaped part. Since each spherical adsorptive carbon granule is almost perfectly spherical and has high fluidity, those granules must be gathered in the lower portion of the bag and the upper portion of the bag must be empty. Otherwise, the spherical adsorptive carbon granules spill out when the bag is opened. Therefore, the spherical adsorptive carbon has to be heaped up in the lower portion of the bag-shaped part and the upper portion of the bag-shaped part must be empty.
  • the pinching device driving mechanism 52 When spherical adsorptive carbon is charged in the tube 90, the pinching device driving mechanism 52 is actuated by a signal from the sequencer 46, and the air expel guides 51 pinch the bag-shaped part of the tube 90 from both sides. When the bag-shaped part of the tube 90 is pinched by the air expel guides 51, the air in the bag-shaped part is expelled. Since the pinching device driving mechanism 52 has a servomotor, the speed of the air expel guides 51 is so controlled that the air expel guides 51 can pinch the tube 90 at such a speed that the air can be expelled quickly without causing the spherical adsorptive carbon to leap in the tube 90. Also, the servomotor controls the air expel guides 51 to pinch the tube 90 at an appropriate pressure to expel the air in the tube 90.
  • the spherical adsorptive carbon is placed in the gap between the lower portions of the paired air expel guides 51.
  • the air expel guides 51 may have a curved face corresponding to the shape of the sealed packets, through. Since the upper portions of the air expel guides 51 are moved toward each other until they contact, no spherical adsorptive carbon can stay in the upper portion of the tube 90.
  • the faces of the air expel guides 51 for pinching the tube 90 are formed by the elastic bodies 51a made of rubber or sponge, they can be deformed even if the shape of the part of the tube 90 containing the spherical adsorptive carbon is slightly changed when they pinch the tube 90. Therefore, the air can be expelled reliably without damaging the tube.
  • the apparatus can be used by replacing only the elastic bodies 51a even if the amount of spherical adsorptive carbon to be packaged in individual packets is changed or the type of granular object to be packaged is changed.
  • a signal from the sequencer 46 actuates the sealing device driving mechanism 42 and the top seal bars 41 pinch transversely the part of the tube 90 immediately above the part from which air has been expelled by the air expel guides 51.
  • the top seal bars 41 are driven by the sealing device driving mechanism 42 separately from the air expel guides 51. Since the sealing device driving mechanism 42 has a servomotor, the top seal bars 41 pinch the tube 90 at an appropriate pressure to seal the tube 90. Since the air expel guides 51 and the top seal bars 41 are driven by different driving mechanisms, both the air expel guides 51 and the top seal bars 41 can pinch the tube 90 at appropriate timing, speed, and pressure.
  • the tube 90 is sealed transversely and closed when pinched by the top seal bars 41.
  • the tube 90 is made of a multi-layer film having an inner layer of a heat-sealable plastic film and can be sealed when pinched by heated top seal bars 41.
  • the top seal bars 41 may seal the tube 90 by means other than heat sealing, such as ultrasonic sealing.
  • the slight time difference can be adjusted to a proper value by the sequencer 46.
  • the time difference is 0.05 to 0.15 seconds, preferably 0.07 to 0.12 seconds.
  • the sequencer 46 may control not only the operation of the top seal bars 41 and the air expel guides 51 but also the entire operation of the apparatus as described later.
  • the top seal bars 41 move down a distance equal to the length of a packet while pinching the tube 90. By this movement, the sealed part made to close the packet containing spherical adsorptive carbon becomes the bottom of the next bag-shaped part of the tube 90.
  • the top seal bars 41 and the air expel guides 51 are supported by the same beam (not shown). The air expel guides 51 move in synchronization with the movement of the top seal bars 41.
  • the packets produced by the separately packaging apparatus 100 for spherical adsorptive carbon according to the first embodiment of the present invention are suitable for packaging spherical adsorptive carbon since they contain a small amount of residual air. It is preferred to heat the spherical adsorptive carbon before sealing with the sealing device 40 since expansion of air in the packets with an increase in temperature after packaging can be prevented more reliably.
  • the hopper for receiving the spherical adsorptive carbon to be packaged may be provided with a heating device as described later.
  • the hopper constitutes a part of the separately packaging apparatus.
  • the heating with a heating device must be conducted before sealing, preferably before expelling air. More preferably, the spherical adsorptive carbon is heated in the hopper in which it stays for a long time.
  • packet means each of the sealed bags containing a granular object measured by the measuring device
  • packetage means each packet or set of packets cut at the sealed parts and discharged from the packaging apparatus.
  • the tube 90 may be continuously transported by another device and the sealing device 40 and the pinching device 50 may be moved up and down in synchronization with the movement of the tube 90.
  • the tube 90 may be transported sequentially by another device but the sealing device 40 and the pinching device 50 do not move up and down, and the transport of the tube 90 may be stopped while it is pinched and sealed.
  • FIG. 2 shows a measuring and packaging apparatus for spherical adsorptive carbon provided with a separately packaging apparatus 100 according to the first embodiment of the present invention.

  • a packing box is placed at the position where the package 92 falls. When a predetermined number of packages 92 are put in the box, the box is carried away.
  • spherical adsorptive carbon to be packaged by the separately packaging apparatus according to the first embodiment of the present invention or packaged by the measuring and packaging apparatus according to the second embodiment of the present invention is described.
  • the spherical adsorptive carbon granule is of porous spherical carbon object with granule size between 0.05 and 1 mm in diameter and a bulk density of 0.51 ⁇ 0.04g/ml. Since the spherical adsorptive carbon granule is of a perfect spherical shape and has high fluidity, it is likely to be scattered in opening a packet. Also, spherical adsorptive carbon contains a large amount of air, and the amount of air tremendously varies depending on temperature.
  • spherical adsorptive carbon when spherical adsorptive carbon is heated from zero to 30°C, it emits 1.46 ml of air per gram. Since spherical adsorptive carbon is heated at 60 to 80°C to fully expel air therefrom and cooled after being sealed in the packets, a vacuum is established in the packets. Therefore, the packets do not expand even if the temperature increases in ordinary circumstances.
  • the present invention is suitably applicable to any granular objects having adsorption ability and a perfect spherical shape.
  • the packaging apparatus, the measuring and packaging apparatus, and the method for producing a package according to the present invention are applicable to other granular objects, especially to granular objects having adsorption ability.
  • Any device for expelling the air in the storage bags can be used instead of the pinching device as the air expelling device.
  • a decompressor may be used. When a decompressor is used, the open end of the storage bag is preferably covered with a screen so that the granular object cannot scatter when the pressure in the storage bag is reduced.
  • the mesh size of the screen must be smaller than the granule size of the granular object so that the granular object cannot pass through the screen even when the screen is deformed.
  • the pressure does not have to be reduced to a high vacuum as long as the pressure can be reduced to such a degree that the air in the storage bag can be expelled.
