Description

  The present invention relates to a packaging box for packaging products such as cosmetics, medicines, CDs, foods, etc., or products such as erasers and soaps with plastic film pieces.

  Packaging that produces a large amount of products in small quantities or packaging with film pieces for the packaging box, repackaging when film pieces are damaged during transportation or management of the goods, etc. I don't get used to it.

  For this reason, in the past, a product or an article to be packaged consisting of its packaging box is wound with a film piece to form a body, and both ends of the film pieces that overlap each other are bonded together (torso), A part of film piece (ear part) protruding from each end of the packaging box was bent (ear fold) and all of them were bonded manually. However, this has the problem of requiring time and effort.

  An object of the present invention is to provide a packaging tool suitable for packaging a small amount of an object to be packaged.

  The present invention relates to a tool for packaging an article to be packaged with a plastic film piece, a stage for placing the film piece and the article to be packaged, and the article to be packaged provided on the stage. A ridge having a height dimension smaller than the thickness dimension, or a ridge attached to the table so as to be movable up and down, and a heat sealer supported by the table so as to be movable up and down and capable of contacting the ridge from above. Prepare. Here, the “height dimension of the article to be packaged” refers to the dimension in the vertical direction when the article to be packaged is arranged on the table for packaging.

  Preferably, at least one of the elevating protrusion and the heat sealer has a notch that forms a gap between the heat sealer and the protrusion so as to allow passage of the film piece when the heat sealer contacts the protrusion. Have.

  Preferably, a guide for the article to be packaged is provided on the table in parallel with the protrusion. This guide can be movable in a direction perpendicular to the ridge. Furthermore, the guide for the said to-be packaged object provided so that it might orthogonally cross with respect to the said protrusion on the said board | substrate can be included.

  Furthermore, it preferably includes a guide for the film piece provided on the table in parallel with the protrusion. This guide can be movable in a direction perpendicular to the ridge.

  Packaging of an article to be packaged with the packaging tool according to the present invention can be performed as follows.

  First, a film piece is placed on a table so that one end of the film piece is placed on a ridge, and then an article to be packaged is placed on the film piece. At this time, the article to be packaged is arranged along the protrusion. As a result, one end of the film piece is bent along the ridge, and faces the packaged object.

  Next, the other end portion of the film piece is wound around the package object. As a result, the other end portion of the film piece protrudes from the packaged object toward the ridge.

  Next, the heat sealer is lowered.

  In the case where the ridge has a height dimension smaller than the height dimension of the article to be packaged, the heat sealer hits the other end of the film, bends it, and then contacts the ridge. Until the heat sealer hits the ridge, the other end portion of the folded film is superimposed on one end portion thereof, and is thermally welded to one end portion of the film by contact with the heat sealer. This completes the so-called trunking.

  On the other hand, in the case where the ridge is attached to the table so as to be able to move up and down, until the heat sealer abuts on the ridge, or further after the ridge descends together with the heat sealer after abutment, The other end portion of the film piece is bent by the heat sealer, overlapped with the one end portion, and thermally welded to the one end portion.

  Here, when at least one of the elevating and lowering protrusions and the heat sealer has a notch, when the heat sealer contacts the protrusions, the other end of the film piece is a gap between them. Accepted and penetrates this. For this reason, the other end portion is bent and thermally welded smoothly without being melted by the heat sealer. The same applies to the ear part in the ear strap described later.

  Then, holding the to-be-wrapped article to be held in hand, the ear is folded on one side of the article to be wrapped, thereby forming a pair of ears facing each other.

  Next, after bending one end of both ears down against the protrusions, when the heat sealer is lowered, the heat sealer hits the other ear, which causes the other ear to bend. And is superposed on the one ear and thermally welded to it (ear covering). Similarly, the packaging work is completed by carrying out the other side earing.

  Referring to FIGS. 1 to 3, a packaging tool according to the present invention, which is used to wrap an article to be packaged using a plastic film piece, is indicated generally by the reference numeral 10.

  The packaging tool 10 includes a table 12 on which the film piece and the article to be packaged are placed, and a ridge 14 and a heat sealer 16 provided on the table 12.

  The illustrated platform 12 is formed of a relatively flat rectangular parallelepiped box and has a flat top plate portion 18. The top plate portion 18 is provided with one slit 20 (FIG. 3) and two slits (one of which is denoted by reference numeral 22) extending in the horizontal direction and the vertical direction, respectively.

  The ridge 14 is made of, for example, a plate-shaped steel material, and is arranged in the slit 20 so as to penetrate vertically. Further, a part of the protrusion 14 is located above the slit 20 through a plate-like body 24, a pair of rods 26, a pair of coil springs 28, and a pair of radial bearings 30 disposed inside the base 12. It is supported by the base 12 so that it protrudes and can be moved up and down through the slit 20.

  The plate-like body 24 continues to the ridge 14 and extends parallel to the top plate portion 18 of the base. Both rods 26 are spaced apart from each other in the lateral direction and are fixed to the top plate 18 of the base at one end thereof and extend downward. Each coil spring 28 is attached to each rod 26 and surrounds each rod 26. Each radial bearing 30 is seated on each coil spring 28. The radial bearings 30 are connected to each other via a connecting plate 32 extending in the lateral direction in parallel with the top plate portion 18 of the base 12.

  Therefore, the ridge 14 descends into the table 12 against the spring force of the coil spring 28 when a pressing force is applied thereto.

  Further, in the illustrated example, a set of bolt and nut assemblies 34 for adjusting the height of the protrusion 14, that is, the height protruding upward from the top plate portion 18 is disposed.

  Each bolt and nut assembly 34 includes a nut fixed to the top plate portion 18 of the base 12, and a bolt that is screwed to the nut, extends through the top plate portion 18 and into the base 12, and contacts the connecting plate 32. (See FIG. 1). By rotating the bolt with respect to the nut, the height position of the connecting plate 32 can be changed, whereby the height of the protrusion 14 can be changed. The height of the ridge 14 can be changed in accordance with the height dimension of the article to be packaged on the table 12. Although the height of the protrusion 14 can be arbitrarily determined, it is preferably set to be not more than half of the height dimension of the article to be packaged.

  The heat sealer 16 includes a heating element 36 made of, for example, a plate-like steel material having substantially the same thickness as the protrusion 14, and a heater (not shown) for heating the heating element 36.

  The heat sealer 16 is supported by the base 12 through the post 38 and the arm 40 so as to be able to be raised and lowered, and is located immediately above the protrusion 14. Therefore, when the heat sealer 16 is lowered, the heating element 36 of the heat sealer 16 comes into contact with or strikes the protrusion 14 from above.

  The post 38 is disposed and fixed in the vicinity of the edge of the base 12 and extends in the vertical direction. The arm 40 is formed of a plate-like body extending in parallel with the top plate portion 18 of the base, and is supported by the post 38 so as to be movable in the vertical direction at one side edge portion. The heat sealer 16 is attached to the other side edge portion of the arm 40 facing the one side edge portion.

  The arm 40 is supported by the post 38 via a linear bearing 42 attached to the arm and a guide way 44 attached to the post 38 and extending in the vertical direction. The movement of the linear bearing 42 along the guide way 44 moves the arm 40 and the heat sealer 16 in the vertical direction along the post 38.

  Further, the post 38 and the arm 40 that is movable with respect to the post are connected to each other by a coil spring 46. The coil spring 46 circulates around a roller 48 attached to the upper side surface of the post 38 and is attached to the lower portion of the post 38 and the arm 40 at both ends thereof. The heat sealer 16 receives the spring force of the coil spring 46 and is held at a position above the protrusion 14. Further, when the arm 40 is lowered against the spring force of the coil spring 46, the heating element 36 of the heat sealer 16 comes into contact with the ridge 14 and further descends together with the ridge 14. When the coil spring 46 expands and contracts due to the lowering and raising of the arm 40, the roller 48 in contact with the coil spring 46 rotates about its axis.

  The lowering operation of the heat sealer 16 can be performed by grasping the handle 50 attached to the arm 40 and pushing it downward.

  The heating element 36 of the heat sealer 16 is provided with a notch 52 (FIG. 1). The notch 52 forms a gap of a size that allows the film piece to pass between the heating element 36 and the protrusion 14 when the heating element 36 is lowered and hits the protrusion 14. The notch can be provided in the ridge 14 instead of the illustrated example, or can be provided in both the heating element 36 and the ridge 14. Alternatively, instead of the illustrated example, the notch 52 can be omitted.

  As will be described later, when the object to be packaged is packaged with the film, the film is placed on the table 12, and the object to be packaged is placed on the film. At this time, one end of the film is placed on the ridge 14.

  The table 12 is provided with a guide 54 for positioning the film piece at this time and a guide 56 for positioning the packaged object. Both guides 54, 56 are arranged along the side edge of the base 12, and have guide surfaces 58, 60 extending in the vertical direction toward the ridge 14, respectively. By aligning the edge of the film piece and the side of the article to be packaged with the guide surface 58 and the guide surface 60, respectively, the film piece and the object to be packaged are vertically aligned so as to be orthogonal to the protrusions 14. Can do.

  Further, the guide 56 for the article to be packaged moves laterally on the film piece guide 54 so that the position of the guide surface 60 can be changed according to the size of the article to be packaged. And fixation to the guide 54 is possible. Specifically, the guide 56 is provided with a slit 62 extending in the lateral direction, and the guide 56 is releasably fixed onto the guide 54 by a bolt 64 extending through the slit 62.

  On the top plate portion 18 of the base, another guide 66 for positioning the packaged object is further provided. The guide 66 is opposed to the ridge 14 and extends in the lateral direction in parallel with the ridge 14, and serves to align the article to be packaged so as to sandwich the article to be packaged with the ridge 14.

  In the illustrated example, the guide 66 is movable in the vertical direction so that the size of the space between the guide 66 and the protrusion 14 can be changed in accordance with the size of the article to be packaged.

  For this vertical movement, a slider 68 and a leaf spring member 70 are disposed under the guide 66. The slider 68 is fixed to the guide 66, a part of which is fitted in the slit 22 and the remaining part is in contact with the top plate part 18. According to this, the guide 66 can be moved along the slit 22, that is, in the vertical direction under the guiding action of the slit 22 with respect to the slider 68.

  The leaf spring member 70 has a hat-shaped cross-sectional shape as a whole, and is fixed to the slider 68 at the center thereof, and both end portions thereof are in contact with and press the top plate portion 18. According to this, the guide 66 is temporarily fixed to the top plate portion 18 by pressing the slider 68 against the top plate portion 18 by the leaf spring member 70. Further, the guide 66 can be moved along the slit 22 against the spring force of the leaf spring member 70.

  Another guide 72 is disposed on the table 12. The guide 72 is attached to another slit extending in the longitudinal direction between the protrusion 14 and the post 38 so as to be movable along the slit.

  The guide 72 extends in the lateral direction in parallel with the ridge 14 and has substantially the same length as the ridge 14. The illustrated guide 72 has an L-shaped cross-sectional shape, one side of which is opposed to the protrusion 14, and the slider 68 and the leaf spring member 70 are attached to the other side as in the guide 66. .

  The guide 72 has a height dimension higher than that of the protrusion 14. For this reason, when the film piece is laid on the base 12 in order to wrap the article to be packaged with the film piece, one end of the film piece is applied to the guide 72 beyond the ridge 14 and aligned therewith. be able to.

  Next, with reference to FIGS. 4-11, the usage method of the packaging tool 10 is demonstrated.

  First, a film piece 80 is placed on the top plate portion 18 of the base 12 (FIG. 4), and a box 82, which is one of the items to be packaged, is placed thereon (FIG. 5).

  The film piece 80 has a rectangular shape as a whole, is preset in a length dimension necessary to wrap the box 82, and has a width dimension shorter than that of the heating element of the protrusion 14 and the heat sealer. In addition, a so-called tear tape 84 used for opening the mouth after packaging is bonded to the illustrated film piece 80. The illustrated box 82 is a relatively flat CD packaging container.

  The film piece 80 is arranged at a predetermined position on the table 12 by applying one end 86 thereof to a guide 72 parallel to the ridge 14 and applying one side edge 88 thereof to a guide 54 orthogonal to the ridge 14. The At this time, the film piece 80 is placed on the ridge 14 and on another guide 66 parallel to the ridge.

  The box 82 is placed on the film piece 80 so that the three sides orthogonal to each other are in contact with the ridge 14, the guide 56 orthogonal to the ridge, and the guide 66 parallel to the ridge 14, respectively. Thereby, the one end part 86 of the film piece is bent along the protrusion 14. The size of the film piece 80 is selected so that the height of the folded one end 86 is slightly higher than the ridge 14 and lower than the height d of the box 82, and the ridge 14 and A distance between the guides 72 is set.

  Further, in the illustrated example, the protrusion 14 and the guide 66 are determined in advance so as to substantially match the size of the box 82 (the length of the table 12 in the vertical direction). From this, when the box 82 is disposed between the protrusion 14 and the guide 66, the film piece 80 is also bent along the guide 66, and the film piece 80 is between the protrusion 14 and the guide 66. Stretched straight.

  Furthermore, the mutual space | interval of the guide surface 58 of the guide 54 of the film piece 80 and the guide surface 60 of the guide 56 of the box 82 is predetermined, Therefore, each side edge of the film piece 80 and each side part of a box A predetermined interval is maintained between.

  In the illustrated example, unlike the example shown in FIGS. 1 to 3, the guide 72 for the film piece 80 and the guides 56 and 66 for the box 82 are respectively arranged in advance at predetermined positions, and It is fixed to the top plate portion 18.

  After the box 82 is placed on the film piece 80, the other end 90 of the film piece 80 is folded back onto the box 82 (FIG. 6). At this time, the film piece 80 is pressed by hand so that it contacts the upper surface of the box 82. As a result, the other end portion 90 of the film piece protrudes from the upper surface of the box 82 in the longitudinal direction of the table 12, extends on the protrusion 14, and terminates before the guide 72.

  Subsequently, the handle 50 of the packaging tool is picked and the heat sealer 16 is lowered (FIG. 7).

  Since the heating element 36 of the lowering heat sealer 16 has a lower ridge 14 than the height of the box 82, the other end 90 of the film piece is bent downward before hitting the ridge 14, The bent end portion 86 is covered.

  Thereafter, when the heat sealer 16 that has come into contact with the ridge 14 is further lowered, the ridge 14 is lowered together. The heat sealer 16 can be lowered until, for example, a part of the protrusion 14 is hidden under the top plate portion 18 of the base. During this time, the other end 90 of the folded film piece is thermally melted by the heating element 36 of the heat sealer that descends while in contact with it, and is thermally welded to the previously folded one end 86 (barrel). After the heat sealer 16 comes into contact with the ridge 14, the heat sealer 16 is further lowered together with the ridge 14, whereby the contact time of the heating element 36 with respect to the bent other end portion 90 can be further increased. It can be made more reliable.

  Here, when the height of the box 82 is large and the other end 90 is relatively long, the other end 90 bent by the heating element 36 is not When sandwiched, there is a gap defined by the notch 52 provided in the heating element 36, so that it is not melted by the heating element 36, and the other end portion 90 is lowered while the protrusion 14 and the heating element 36 are lowered. Rubs through the gap defined by the notch 52, overlaps the one end 86, and is heat-welded immediately thereafter.

  Thereafter, the box 82 with the waistline is taken out, and an ear fold is applied to one of both side edges of the film piece 80 by hand to form a pair of ear portions 92 facing each other (FIG. 9).

  Next, the box 82 subjected to the ear fold is placed on the top plate portion 18 of the table so that the both ear portions 92 are positioned above and below the ridge 14, and is advanced toward the ridge 14. Thereby, the lower ear | edge part 92 is applied to the protrusion 14, and it bends along the side part of the box 82 (FIG. 10).

  Next, while the box 82 is pressed by hand so that the bent lower ear portion 92 is kept pressed against the protrusion 14, the heat sealer 16 is lowered in the same manner as in the case of the waistline (FIG. 11). .

  As a result, the other upper ear portion 92 is bent, overlapped with the lower ear portion 92 that has been bent first, and heat-welded to the lower ear portion 92 (earrest). At this time, when the ear 92 is relatively long, the ear 92 rubs through the gap defined by the notch 52.

  Thereafter, the other end of the both side edges of the film piece 80 is subjected to the same operation as that of the one side edge to perform the above-mentioned ear tension, thereby completing the packaging of the box 82 with the film 80.

  The ridge 14 may be a ridge that is fixed on the base 12 and does not move up and down, instead of the illustrated example in which the ridge 14 can move up and down. In this case, the protrusion has a height dimension smaller than the height dimension of the article to be packaged, preferably a height dimension equal to or less than half of the height dimension of the article to be packaged. By setting the height dimension of the ridge in this way, the overlap of the other end portion on the folded one end portion of the film piece in the waistline and the one bent one ear portion in the ear strap. It is possible to ensure the overlapping of the other ears of the two, and to ensure thermal welding between both ends and both ears. In this example, since the ridge does not descend, the trunk and the ear lacing are completed when the heating element 36 of the heat sealer contacts the ridge.
