Description

  The present invention relates to an overwrapping package, particularly, an overwrapping package in which a product having a rectangular parallelepiped shape such as a confectionery folding box is wrapped in one sheet-shaped packaging material (hereinafter, referred to as wrapping paper), and a finished state of the packaging. The present invention relates to a packaging volume increasing device that stacks packages from the lower side while maintaining good performance.

  Conventionally, as a package for wrapping a product having a rectangular parallelepiped shape such as a confectionery folding box with a single rectangular wrapping paper, the wrapping paper is wrapped around the product and the tubular protruding end of the wrapping paper protruding from both ends of the product As for the above, there is known an overwrapping package in which the side edge portions are folded along the end surface of the product and the upper and lower edge portions of the end portion are folded along the end surface of the product (see Patent Document 1).

  In the above-mentioned overwrap packaging, generally, the packaging process as shown in FIG. 4 is followed to wrap the wrapping paper around the product. That is, a large number of wrapping sheets S are prepared in a stacked state (step (1)), and products C to be packaged are also stacked and prepared in a vertically stacked state (step (2)). The accumulated products C are sent out one by one, for example, from the one located at the bottom (step (3)), and the top one of the wrapping paper S is prepared to be sent out from the stack. (Process (4)).

  The product C sent to the push-up position in the stroke (3) is lifted upward from below by a lifting device such as an elevator (stroke (5)). The wrapping paper S prepared in the step (4) is sent out onto the push-up path of the product C (step (6)). The product C is further pushed up toward the wrapping paper S placed above, and the top surface c1 of the product C and both side surfaces c2 and c2 intersecting with the top surface c of the wrapping paper S folded along with the pushing up. It is covered with s1 and side surface parts s2, s2 (step (7)).

  By folding one flap portion s3 of the wrapping paper S, a part of the bottom surface c3 of the product C is covered, and at the same time, one lateral side edge portion s6 of the wrapping paper S is folded along the end surface c4 of the product (step (8 )). After that, by folding the other flap portion s3 of the wrapping paper S, the remaining portion of the bottom surface c3 of the product C is covered, and the folded front end overlaps with the flap portion s3 previously folded. The other lateral edge portion s6 of the wrapping paper S is folded along the end surface c4 of the product, and the upper edge portions s4, s4 of the wrapping paper S are folded back upward (step (9)).

  The lower edge portions s5, s5 of the wrapping paper S are folded over the end surfaces c4, c4 of the product C to cover a part thereof, and the upper edge portions s4, s4 folded back upward are folded back to a horizontal state ( Step (10)). When the product C is pushed up together with the wrapping paper S, the upper edge portions s4, s4 in the horizontal state are bent downward to the end surfaces c4, c4 of the product C and the remaining portions on the end surfaces c4, c4. And the folded tip overlaps the lower edge portions s5 and s5 that are already bent on the end surfaces c4 and c4 of the product C (step (11)).

  In the folding of the upper edge portions s4, s4 (stroke (11)), in the case of side folding, the upper edge portions s4, s4 are folded over the lower edge portions s5, s5 and the end surfaces c4, c4 of the product C are folded. The packaging is completed when the product reaches a state of being covered without protruding, and the packaged products C are stacked from below (step (11s)). In the case of underhold, since the heights of the upper side edge portions s4, s4 and the lower side edge portions s5, s5 are higher than the heights of the end surfaces c4, c4 of the product C, the upper side edge portions s4, s4 are removed in the final step. The product C is bent to the bottom surface c3 and is overlapped with the already folded flap portions s3 and s3 (step (11u)). The stacked packaged products C are carried out in a subsequent step (for example, a cardboard box packing step) (step (12)). In the overwrapping, the folding of the wrapping paper S is performed not only by the folding tool while the product C is stopped, but also when the product C moves in the vertical or horizontal direction (vertical or horizontal direction) together with the wrapping paper S. , It is also done by using the relative movement with the folding tool.

  By gluing glue or the like on the overlapping portion of the wrapping paper and gluing the wrapping paper, the package P of the wrapping paper S of the product C is completed (state shown in step (11) of FIG. 4). This overwrapping packaging can be applied not only to the confectionery folding box but also to a rectangular parallelepiped such as a book for packaging such articles.

  For such overwrapping packaging, a glue spraying device including a glue spraying device (glue spraying nozzle) called a glue gun is applied. 5 and 6 are a side view and a front cross-sectional view (A-A cross-sectional view of FIG. 5) of the wrapping paper supply device in which the glue jetting device is incorporated in the overwrap packaging machine. In order to paste the product C onto the wrapping paper S to be wrapped, a glue gun 61 as a glue spraying device for spraying the glue is provided at a fixed position on one side of the wrapping paper supply device 60. The glue gun 61 sprays glue as an adhesive toward the wrapping paper S that is transported to a position that intersects the vertical transport path of the product C, and a line is formed at a position along the lower edge of the wrapping paper S. The glue G is attached in a necessary and appropriate pattern such as a shape. When one flap portion of the wrapping paper is folded into the bottom surface of the package S and then the other flap portion to which the glue G is attached is folded, the overlapping portion of the wrapping paper S is bonded with the glue G (see FIG. 4). See Stroke (9), which is the body-wrapping process). After that, a side edge portion (also referred to as an ear) protruding in the front-rear direction of the product C is folded, and at this time, an adhesive is sprayed by another glue gun fixed at a predetermined position, and the upper side of the moving packaging material S is moved. The glue is attached to the inside of the edge portion. The upper edge portion to which the glue is attached is folded over the folded lower edge portion (see steps (10) to (11), which are the side folding steps in FIG. 4), so that the upper and lower side edge portions overlap each other. The parts are bonded and the packaging process ends.

  In the step (11) of FIG. 4, the product C and the wrapping paper S, which are wrapped by overwrapping, are pushed upward by the wrapping volume raising device, and the finally obtained wrapping body P moves from the bottom to the top. They are stacked in order. FIG. 7 is a perspective view showing an example of a packaging volume increasing device. The packaging volume raising device (hereinafter abbreviated as “stacking device”) 70 includes a pair of stacking plates 71, 71 whose surfaces are parallel to each other and horizontally opposed to each other, and a space between the stacking plates 71, 71 is a package. It is a stacking space 72 in which the bodies P are stacked. The horizontal distance W between the stacking plates 71, 71 corresponds to the width size of the product C. A plurality of holes 73 that are long in the vertical (up and down) direction are formed side by side in an orderly manner in the horizontal direction in each stacking plate 71, and a stacking claw 74 is provided in each long hole 73 so as to be retractable toward the stacking space 72 side. (Reference numerals 73 and 74 are attached only to a part). The stacking claw 74 is lightly spring-biased so as to project from the elongated hole 72 to the stacking space 72 side, but when the package P rises, it is pushed back into the elongated hole 73 and the package P is stacked. Tolerate. The stacking claw 74 functions to prevent the package P from falling from the elongated hole 73 to the stacking space 72 side by the spring bias after the package P is lifted and passed. The stacking plates 71, 71 function to move up in the stacking space 72 or guide the movement of the packages P stacked in the stacking space 72.

In each of the long holes 73, a side heater 75 is arranged at a position directly above the stacking claw 74 so as to face the stacking space 72 side. The side heater 75 has a height corresponding to the height of the package P, and the side heater 75 has the adhesive adhered to the folded upper edge portions s4, s4 and lower edge portions s5, s5 (see FIG. 4). Heat to accelerate curing. Under each stacking plate 71, folding tools 76, 76 for folding the upper edge portions s4, s4 are arranged. Further, in the stacking space 72, a pair of lifting tools 77, 77 are arranged so as to be able to move up and down. The push-up tools 77 are arranged near and in parallel with the stacking plate 71. In this example, it is formed in the bent portion upper edge is folded in the horizontal direction (stacking plate 71 side in the vicinity) of the push-up member 77, comb-like structure 78 (plurality of teeth arranged in a comb-like Portion and a narrow tooth bottom portion connecting the bottom side of the tooth portion. Only one of them is shown). The package P is supported on both sides of its bottom surface by the comb-shaped structures 78, 78 of the push-up tools 77, 77 ( discretely at the tooth portions ) .

As shown in the step (10) of FIG. 4, the product C and the wrapping paper S placed on the push-up tools 77, 77 are in a state in which the upper edge portions s4, s4 of the wrapping paper S are not folded yet ( The state just before the completion of the overwrapping). When the product C in the body-wrapped state is lifted while being placed on the push-up tools 77, 77, the upper edge portions s4, s4 are relatively folded down by the folding tools 76, 76, and the product is already manufactured. The lower edge portions s5 and s5 folded on the end faces c4 and c4 of C are folded (adhered with glue). When the comb tooth-shaped structure 78 of the push-up tool 77 passes through the stacking claw 74 without interfering with the stacking claw 74 and is pushed up until the package P passes the height position of the stacking claw 74, the push- up tool Even if 77 is lowered, the package P is supported by the stacking claws 74 so as not to drop, and at the same time, the side heater 75 cures and accelerates the glue. Both sides of the packaging body P are regulated by the stacking plates 71, 71, and when the next packaging body P is similarly folded, the packaging body P is pushed up from below toward the previously treated packaging body P. In the stacking space 72, the stacked spaces are sequentially stacked.

  When the size of the product C is changed, the stacking device 70 handles the size change. FIG. 8 is a diagram for explaining the correspondence on the device side when the size of the stacking device shown in FIG. 7, particularly the width size of the package is changed. FIG. 8A is a diagram illustrating a corresponding position when the width of the product C is the minimum size, FIG. 8A is a side view, and FIG. 8A is a plan view. The stacking plates 71, 71 and the lifting tools 77, 77 are placed at positions closest to each other. FIG. 8B is a diagram illustrating the corresponding position when the width of the product C is the maximum size, FIG. 8B is a side view, and FIG. 8B2 is a plan view. The stacking plates 71, 71 and the lifting tools 77, 77 are placed at the positions most distant from each other.

  When the size of the stacking device 70 is changed according to a large box size (size of the product C), there may occur a problem that the finished state of the package as shown in FIG. 9 deteriorates. In FIG. 9A, since the box size of the packages P stacked along the stacking plates 71, 71 is large, the flap part s3 of the left and right flap parts of the wrapped wrapping paper S which is folded later is shown. However, since it is not sufficiently adhered to the flap portion s3 that has been folded in advance by the glue and is not completely supported by the push-up tools 77, 77, it shows a state in which it hangs down. Further, in FIG. 9B, since the box size is large and the rigidity of the box is low, the package P is stacked while being regulated along the stacking plates 71, 71, but the package P is pushed up. , 77 as fulcrums, and the package P has a warped shape as a whole, resulting in a poor appearance.

  Hereinafter, an embodiment of a package volume increasing device in an overwrapping package according to the present invention will be described with reference to the attached drawings. FIG. 1 is a perspective view showing an example of a push-up tool and a support member (FIG. 1 (a)) used in a package volume raising device in an overwrap packaging according to the present invention in comparison with a conventional case (FIG. 1 (b)). It is a figure.

The push-up tools 7, 7 are the same as those described above as the push-up tool 77 in FIG. 7 and the like, but as shown in FIG. 1 (a), they are made of metal and have a weight reducing hole. consist of plate material, and the vertical plate 7a, consist its upper end adjacent stacked plates (not shown in FIG. 1) bent portion that has been bent horizontally side, the bent portion is comb teeth The structure 8 is formed. The comb tooth-shaped structures 8 and 8 are bent toward the nearest stacking plate (not shown) side, and the upper surfaces thereof are flush with each other to form a horizontal surface. Can support the bottom surface of.

The support member 10 is arranged so as to be expandable between the push-up tools 7, 7. The support member 10 includes two plate-shaped support pieces 11 and 11, and one ends 11 a and 11 a of the support pieces 11 and 11 are pivotally connected to each other by a hinge 12. The other ends 11b, 11b (only one of which is shown) of the supporting pieces 11, 11 are hinges 13, 13 (only one is shown, but the other is shown) with respect to the upper portions of the vertical plate members 7a, 7a of the lifting tools 7 , 7, respectively. May have the same structure) and are rotatably connected to each other. The upper edge surfaces 14, 14 of the support pieces 11, 11 are aligned in height so as to be flush with the upper surfaces 9, 9 of the comb tooth-shaped structures 8, 8. The support member 10 is assembled in such a manner that the support pieces 11 and 11 expand in a V shape when seen in a plane. In the illustrated example, the support pieces 11 and 11 are long and slender straight plate members having the width direction vertically arranged, but the support members 11 and 11 are not limited to this. For example, a rod-shaped object such as a round bar or a square bar or a corrugated plate having a shape and structure capable of supporting the bottom surface of a semi-wrapped body in a body-wrapped state or a packaged body in an overwrapped state can be used. Further, the hinges 12 and 13 may be similar to hinges used for opening and closing doors, for example. The position of the head above the hinges 12 and 13 is set below the upper edge surface 14 of the support piece 11.

  When the space between the push-up tools 7, 7 is enlarged or reduced as the size of the product C is changed, the supporting pieces 11, 11 are rotated around the hinges 12 and 13 in accordance with the change. , The degree of opening of the V-shaped connection changes while maintaining the V-shaped connection between the push-up tools 7, 7, and even for the product C of a larger size, the bottom surface of the product C can be surely spread over a wide range.

Therefore, it is possible to obtain a good-looking overwrapping package by preventing the wrapping paper S from hanging down from the bottom side of the product C and warping of the product C (or the overwrapping package P) during the overwrapping. it can. It should be noted that FIG. 1B shows a situation in which the distance W between the push-up tools 77, 77 is fixed and cannot be changed.

  FIG. 2 shows another example of the push-up tool used in the package volume raising device in the overwrap packaging according to the present invention. The support member included in the push-up tool shown in FIG. 2 is composed of two or three linear plate-shaped support pieces. The support member 20 shown in FIG. 2A includes two linear plate-shaped support pieces 21 and 21, and the support pieces 21 and 21 are rotated by a rotation shaft 22 at the center in the longitudinal direction thereof. It is movably connected. Since the supporting pieces 21 and 21 intersect each other, the crossing structure 25 allows the supporting pieces 21 and 21 to rotate with respect to each other. That is, as the intersecting structure 25, notches 25a, 25a that can be combined with each other with a gap therebetween so as to loosely join together are formed in the central portion of each support piece 21, and the rotating shaft 22 has the notches 25a, 25a. 25a, it extends in the vertical direction and is rotatably connected to each other.

One ends 21a, 21a of the support pieces 21, 21 are rotatably connected to the upper portions of the vertical plate members 7a, 7a of the push-up tools 7 , 7 by hinges 23, 23, respectively. The other ends 21b, 21b of the support pieces 21, 21 can be slid along the push-up tools 7, 7 by the slide structures 26, 26 with respect to the upper portions of the vertical plate members 7a, 7a of the push-up tools 7 , 7, respectively. Is linked to. Although only one of the hinge 23 and the slide structure 26 is shown in the drawing, the other has the same structure. The slide structure 26 includes a slide rail 26a attached to the lifting tool 7 and an engagement piece 26b that is provided at the end 21b of the support piece 21 and is slidable by fitting with the slide rail 26a. ing. Thus, the support member 20 is assembled in such a manner that the support pieces 21 and 21 expand between the push-up tools 7 and 7 into an X-shape when viewed in a plan view.

  When the space between the push-up tools 7, 7 is enlarged or reduced as the size of the product C is changed, the support pieces 21, 21 are corresponding to the one end portions of the push-up tools 7, 7. 21a and 21a rotate by hinges 23, and rotate with respect to each other about a rotation shaft 22 in a central portion. The other ends 21b, 21b are displaced with respect to the push-up tools 7, 7, but the positional displacement is absorbed by the slide structures 26, 26. The supporting member 20 changes the opening degree of the X-shaped connection while maintaining the connection intersecting in the X-shape, so that the bottom surface of the supporting member 20 is even and symmetrical over a wide range even for the product C of a larger size. Can be physically supported. The shapes of the support pieces 21, 21 and the upper edge surfaces 24, 24, etc. are the same as in the case of the example shown in FIG. Therefore, similarly to the example shown in FIG. 1A, the sagging of the wrapping paper S and the warp of the body-wrapped semi-wrapping body or the overwrapping package P are prevented to obtain a good-looking overwrapping package. You can In addition, when connecting in an X shape, the configuration becomes complicated, but the two support pieces 21 and 21 are configured to be expandable and contractable like a nesting type, and the centers of both support pieces 21 are rotated by the rotation shaft 22. The slide structure 26 may not be adopted by rotatably connecting the both ends of each supporting piece 21 to the push-up tools 7, 7 by hinges 23, 23.

The support member 30 shown in FIG. 2 (b) includes three linear plate-shaped support pieces 31, 31, 31, and the support pieces 31, 31, 31 are provided between the push-up tools 7, 7. The respective end portions 31a, 31a and the end portions 31b, 31b are pivotally connected by the hinges 32, 32, and the push-up tools 7 , 7 are hinged 33, 33 on the upper portions of the vertical plate members 7a, 7a . It is pivotally connected. The support member 30 is assembled in such a manner that the support pieces 31, 31, 31 expand in an N-shape in which the support pieces 31, 31, 31 are connected in series as seen in a plane between the push-up tools 7, 7. Since the support pieces 31, 31, 31 are rotatably connected to each other, the shape may not be determined as a continuous structure. Therefore, it is preferable that the hinges 32, 32 connecting the supporting pieces 31, 31, 31 have a light torsion spring incorporated therein to narrow the supporting pieces 31, 31, 31 to maintain a stable form.
