Definitions

  • the present invention relates to a method and apparatus for packaging an extraction bag to obtain a package in which the extraction bag having four triangular surfaces is closed in an exterior bag.
  • Tea bags of black tea, green tea, herb tea and the like, as well as extraction bags of soup such as dried sardine and dried bonito are made from a belt-like water filter sheet.
  • the water filter sheet is formed into tetrahedral or pyramid-like bags having four triangular surfaces, and each of the bags is filled with extraction materials such as tea leaves so as to be used as so-called a trigonal-pyramid pack.
  • the trigonal-pyramid pack include a trigonal-pyramid pack with a thread tag in which a hanging thread and a tag to be used as a knob piece are attached to its outer surface.
  • the trigonal-pyramid packs are widely marketed in the form of being individually packaged with a flat bag-type exterior bag which is formed of an air-impermeable outer packaging film.
  • Individual packaging machines which industrially perform individual packaging of trigonal-pyramid packs have also been known (Patent Literatures 1 and 2).
  • a trigonal-pyramid pack is fed to a cylindrical guide and is pressed into an exterior bag by a pusher, and the exterior bag is sealed so as to manufacture a package of the trigonal-pyramid pack. Since an extraction bag sheet to form the triangular pack is a fabric, such as a thin nonwoven fabric or nylon gauze, the trigonal-pyramid pack is easily squashed inside the exterior bag by simple action of being pressed by the pusher.
  • the triangular pack is irregularly squashed, which may provide the pack with an unnecessary thickness and makes the pack bulky. As a result, an outer size of the pack may become unstable. Furthermore, when the triangular pack has a thread tag, the tag may be folded, the tag may be detached from the trigonal-pyramid pack, or a hanging thread is bit into a seal portion at the edge of the exterior bag in the process of the triangular pack being squashed. This leads to increase in the possibility of producing defective products.
  • an object of the present invention is to package a trigonal-pyramid pack with an exterior bag by closing the trigonal-pyramid pack in the exterior bag in the state of being folded flat in a fixed form.
  • the present inventors have found that a trigonal-pyramid pack can be folded flat if one side or one surface of the trigonal-pyramid pack is folded into two and then surface-pressing of the trigonal-pyramid pack is performed and that the above-stated object can be achieved by packaging the flat-folded trigonal-pyramid pack.
  • the present invention has been completed based on the finding.
  • the present invention is a method for manufacturing a package in which an extraction bag having four triangular surfaces is stored in an exterior bag, the method including:
  • the extraction bag is an extraction bag with a thread tag in which a tag joined to a hanging thread is attached to a triangular surface, and in the direction regulation step, the direction of the extraction bag is regulated to be a direction in which the triangular surface with the tag attached thereto is not folded in the folding step.
  • the present invention is an apparatus for manufacturing a package in which an extraction bag having four triangular surfaces is stored in an exterior bag, the apparatus including:
  • the extraction bag is an extraction bag with a thread tag in which a tag joined to a hanging thread is attached to a triangular surface, and the direction regulation device regulates the direction of the triangular surface with the tag attached thereto to be a direction in which the surface is not pressed inside by the pressing device.
  • the trigonal-pyramid pack can be folded flat, and a package in which the flat folded trigonal-pyramid pack is stored in an exterior bag can be obtained. Therefore, it becomes possible to prevent the package of the trigonal-pyramid pack from becoming unnecessarily bulky.
  • a package in which a trigonal-pyramid pack is folded flat without the tag being folded and is sealed in an exterior bag. Therefore, in individual packaging of the trigonal-pyramid packs, it becomes possible to prevent production of defective products having the tag being folded, with the tag being detached from the trigonal-pyramid pack, or having the hanging thread being bit into a seal section at the edge of the exterior bag.
  • FIG. 1 is a schematic view of a manufacturing apparatus 1A which performs a package manufacturing method of one embodiment of the present invention.
  • the package manufacturing apparatus 1A is an apparatus configured to manufacture a package 10 in which an extraction bag 2 having four triangular surfaces, such as a tetrahedral tea bag, is individually packaged with an exterior bag 11 that is formed into a flat bag by three-side sealing.
  • the package manufacturing apparatus 1A generally includes: a direction regulation device 20 which performs a direction regulation step of regulating the direction of the extraction bags 2 which are continuously fed from a belt conveyer 90 to be a specified direction; a pressing device 30 which performs a pressing step of pressing the extraction bag 2 so that one surface or one side of the extraction bag 2, which was fed from the direction regulation device 20 to have the specified direction, is folded into two; a folding device 40 which performs a folding step of folding the extraction bag 2 flat by surface-pressing of the extraction bag 2 from both front and rear side of surfaces that are overlapped upon being folded into two by the pressing device 30; and a package forming device 50 which performs a packaging step of forming a package 10 by individually packaging the extraction bag 2 folded flat by the folding device 40 with an outer packaging film 12.
  • the extraction bag 2 to be fed to the package manufacturing apparatus 1A may be manufactured by a publicly known method which includes: forming a belt-like water filter sheet into a cylindrical shape by bonding opposite edges of the water filter sheet to each other; and alternately forming a first horizontal seal obtained by squashing the cylindrical body and welding/melt-cutting the cylindrical body in a width direction and a second horizontal seal obtained by welding/melt-cutting the cylindrical body in another width direction that is orthogonal to the previous width direction while filling contents in between these horizontal seal formations.
  • the extraction bag 2 may be an extraction bag with a thread tag as illustrated in FIG.
  • a tag 4 joined as a knob piece to one end of a hanging thread 3 of the extraction bag 2 is attached to a triangular surface of the extraction bag 2.
  • the tag 4 is stripped from the surface of the extraction bag 2, so that a bag body 2' can be hung with a hanging thread 3 that extends from the tag 4 as illustrated in FIG. 5(2) .

  • the direction regulation device 20 has a rocking mechanism 25 including a rocking cylinder 251, a rocking cam 252, and a rocking cam follower 253 so that oscillation can be provided to the extraction bag 2 retained by the hopper-type holding device 22 in a rocking region R that is a specified range in the direction of arrow A starting from a position P1 where the hopper-type holding device 22 receives the extraction bag 2 from the belt conveyer 90.

  • the direction regulation device 20 has a tag direction regulation mechanism 27 which regulates, when the extraction bag 2 is an extraction bag with a thread tag, the direction of the tag 4 of the extraction bag 2 which was fitted into the placement section 23, so as to prevent the tag 4 from being folded by the pressing device 30 and/or the folding device 40 on the downstream side. More specifically, as illustrated in FIGS. 1 and 2 , in order to enable the direction of the tag 4 of the extraction bag 2 to be detected at an observation position P2 downstream from the rocking region R, two tag direction confirmation cameras 271 (271p, 271q) are provided to horizontally observe the extraction bag 2, which is at the observation position P2, from three directions, and a CPU 272 is provided for controlling the cameras 271.

  • the manufacturing apparatus 1B operates as follows. First, the extraction bags 2, which are continuously fed from the apparatus for manufacturing the extraction bag 2, are received one by one at the first placement portion 111 of the tray 110.
  • the extraction bag 2 When the extraction bag 2 is of a type with a thread tag, it is necessary to prevent the tag 4 from being folded when the extraction bag 2 is pressed with the rotating disk 120. Accordingly, when the extraction bag 2 is transferred from the first placement portion 111 to the second placement portion 112, the direction of the extraction bag 2 is properly changed so that the triangular surface with the tag 4 attached thereto is positioned to face the side of the extraction bag 2 which is to be pressed by the rotating disk. More specifically, in the case of the extraction bag fed from an apparatus for industrially manufacturing trigonal-pyramid packs (such as the apparatus described in International Publication No.
  • the direction of the lowermost side of the extraction bag 2 that is received in the first placement portion 111 of the tray 110 and the direction of the surface with the tag 4 attached thereto are alternately changed as illustrated in FIG. 14A . Accordingly, for example, when the direction of the lowermost side of the extraction bag 2 that is received in the placement portion 111 is aligned with the direction of the conveying direction of the extraction bag 2 as illustrated in (I), the extraction bag 2 is transferred to the placement portion 112 without changing the direction of the extraction bag 2.
  • the extraction bag 2 may be transferred to the placement portion 112 without changing the direction of the extraction bag 2.
  • the extraction bag 2 may be rotated 90 degrees inside the level plane and be transferred to the placement portion 112.
  • the tray 110 retaining the extraction bag 2 passes under the rotating disk 120.
  • the upper end side of the extraction bag 2 is pressed inside by the rotating disk 120 in the direction vertical thereto, so that the side may finely be folded into two.
  • the extraction bag 2 is passed between the belts 130 facing each other, by which the extraction bag 2 is folded flat.
  • the flat folded extraction bag 2 may be inserted into the outer packaging film 12, which is folded into two by the package forming device 50 with the same means as the extraction device and the transfer device having grippers as described before.
  • a package manufacturing apparatus 1C illustrated in FIG. 15 includes a bucket table 140 as the direction regulation device which retains the extraction bag 2 so that one side of the extraction bag 2 makes the lowermost side.
  • FIG. 16 is an explanatory view of the action inside the bucket 141.
  • a right-side column of FIG. 16 illustrates cross sectional views of the bucket 141 as viewed from A direction in FIG. 15 (a rotation direction of a bucket table), and a left-side column illustrates cross sectional views of the bucket 141 as viewed from B direction in FIG. 15 (a radial direction of rotation of the bucket table).
  • an upper end opening of the bucket 141 is generally a square shape so that the extraction bag 2 thrown in the bucket 141 is retained with one side of the extraction bag 2 making the lowermost end, the bottom thereof is formed narrow so as to have a triangular cross section as viewed from the A direction in FIG. 15 .
  • the manufacturing apparatus 1C includes a pressing plate 150 to be used as a pressing device which presses one side of the extraction bag 2 that makes an uppermost side in the bucket 141, the pressing plate 150 being pressed with a plate surface thereof being in the direction vertical to one side that is the uppermost side of the extraction bag 2.
  • the manufacturing apparatus 1C also includes pressure plates 160 to be used as a folding device which holds two facing surfaces of the extraction bag 2 inside the bucket 141.
  • the pair of pressure plates 160 of the folding device are in the state where both the plates are opened in a V shape along the inner wall of the bucket 141, when the bucket 141 receives the extraction bag 2.
  • the opening width of the V shape is variable and the pair of pressure plates 160 can take a position where the opening of the V shape is closed at the center of the bucket.
  • the bucket 141 when the bucket 141 receives the extraction bag 2 from the belt conveyer 90, the bucket 141 retains the extraction bag 2 so that one side of the extraction bag 2 makes a lowermost end ( FIG. 16(a) ).
  • the pressing plate 150 presses the uppermost side of the extraction bag 2 that is retained on the bucket 141, and also narrows the opening of the pressure plates 160 which is opened in the V shape along the inner wall of the bucket 141 ( FIG. 16(b) ).
  • the extraction bag 2 is folded flat and further pressed downward with the pressing plate 150, and the flat folded extraction bag 2 is dropped to a bottom receiving guide 142 ( FIG. 16(c) ).
  • the bottom receiving guide 142 is a plate-like member which opens and closes a lower part of the bottom of the bucket 141.
  • a plate-like side guide 143 stands on each side of the bottom receiving guide 142 to help the extraction bag 2 dropped to the bottom receiving guide 142 to be retained there.
  • the extraction bag 2 dropped to the bottom receiving guide 142 is held by the gripper 170, and the bottom receiving guide 142 is removed from the lower part of the bottom of the bucket 141, so that the extraction bag 2 is sent to the package forming device 50 with use of the gripper 170 ( FIG. 16(d) ).
