It is an object to provide a method and a boxing device for a self-supporting gusset bag used therein.

In order to achieve the above-described object, the boxing method for a self-supporting gusset bag according to the present invention includes placing a plurality of self-supporting gusset bags having a heading portion at the top in a self-supporting posture from above in a box with an open top surface. When the upper surface flap is closed and put into a packing state, the heading portions of the plurality of gusset bags placed in the box are used to support the heading portion by using a bending tool and a support tool each made of a plate-like or bar-like member. While supporting the root of any one of the heading parts with the longitudinal edge of the tool , press the gusset bag from the front side with the longitudinal edge of the folding tool and attach a crease in the back direction to each heading part. The top flaps are closed after going and finishing folding creases in the headings of all gusset bags in the box.

  According to this configuration, all the gusset bag headings in the box are folded in the back direction and then the top flap of the box is closed, so that the heading part bends neatly, causing extra wrinkles and crumpling. After unpacking and taking it out of the box, the customer can see the beautiful heading part. Further, since the height of the box can be lowered by the amount of bending of the heading portion, the box can be reduced in size, the cost of the box itself can be reduced, and distribution costs such as storage and transportation can be reduced.

  Further, the present invention provides the above-described method for packing a self-supporting gusset bag, wherein the gusset bags are aligned in the box with each front side facing one direction, and the folding tool presses one of the heading portions. The head portion of the gusset bag lined behind the gusset bag to which the heading portion belongs, or the root portion of the heading portion is supported by a support from the back side of the gusset bag.

  According to this configuration, the gusset bag that is about to be pushed down by the heading portion is supported from behind by the support member, and the bending of the heading portion by the bending tool can be reliably performed.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a state in which a self-supporting gusset bag 1 is put in a cardboard box 10. As shown in FIG. 2, the gusset bag 1 has a total of 12 rows in 3 rows and 4 rows, with the left-right direction of the drawing as a column and the vertical direction of the drawing as a row. It is directed to the left side. That is, among the four gusset bags 1 arranged in the horizontal direction in the figure, the leftmost one is the head of the row, and the rightmost one is the tail of the row. For convenience of explanation, the subscripts “a”, “b”, “c”, and “d” are appended to the code “1” of the gusset bag in order from the top of the column as necessary. Similarly, the subscripts “a”, “b”, “c”, and “d” are added to the code “4” of the heading portion as necessary. The three columns and four rows are merely configuration examples, and are not limited thereto.

  The box 10 is a rectangular parallelepiped corrugated cardboard box that is generally used, and has an inner lower surface flap 11 connected to the lower edge of two opposite sides of the body (upper and lower sides in FIG. 2), and the opposite two that form a right angle thereto. A lower outer flap 12 is connected to the lower edge of the side (the side located on the left and right in FIG. 2). Further, the upper inner side flap 13 (see FIG. 7) is connected to the upper edge of the two opposite sides of the body (sides located up and down in FIG. 2), and the two opposite sides (right and left in FIG. 2) are perpendicular to it. The outer upper surface flap 14 is connected to the upper edge of the side.

  After the box 10 is opened, the lower surface inner flap 11 and the lower surface outer flap 12 are bent inward, and the lower surface inner flap 11 and the lower surface outer flap 12 are bonded with a hot melt adhesive, or the lower surface outer flap 12 is joined to the joint. Sealing tape is applied to form a box. The upper surface inner flap 13 and the upper surface outer flap 14 are opened outward. Although the box 10 of FIG. 1 is drawn with the upper outer flap 14 bent to a horizontal state, it is not necessary to bend so far, and it may be left in an inclined state. The same applies to the upper surface flap 13.

  As shown in FIG. 1, a plurality of, in this case, a total of 12 self-supporting gusset bags 1 in 3 rows and 4 rows as described above are placed in a box 10 whose upper surface is open. Using a chuck device (not shown) that is normally used in the above, it is inserted in the self-standing posture from above. 1 and 2 show the state after insertion.

  Subsequently, a folding crease in the back direction is attached to each heading portion 4 of the gusset bag 1 with a folding tool 20 and a support tool 21 (see FIG. 3). The bending tool 20 is a flat plate member that is gently inclined, and the support member 21 is an L-shaped plate member that is inclined at a slightly steep angle as compared to the bending tool 20. Arranged so that the edges face each other. The bending tool 20 presses the heading part 4 from the left side of the figure at the edge in the longitudinal direction of the plate, and the supporter 21 supports the root part of the heading part 4 from the right side of the figure at the edge in the longitudinal direction of the board. Both the folding tool 20 and the support tool 21 have a width that can cover the gusset bags 1 for three rows, and the three heading portions 4 arranged side by side are bent at a time.

  One or both of the bending tool 20 and the support tool 21 may be formed of a rod instead of a plate. It is preferable to have an appropriate bent shape so as not to break through the gusset bag 1 at the end of the rod. The bending tool 20 formed of a rod presses the heading portion 4 from the left side of the figure at the longitudinal edge of the rod, and the support member 21 formed of a rod is the root portion of the heading portion 4 at the longitudinal edge of the rod. Will be supported from the right side of the figure. In addition, it is not necessary to align both the bending tool 20 and the support tool 21 with a board or a stick. It may be an arrangement in which one is a plate and the other is a bar.

  The bending tool 20 and the support tool 21 are two-dimensionally moved by being supported by a two-dimensional moving device (not shown) that is commonly used in the seed boxing device and capable of horizontal movement and vertical movement. The two-dimensional movement device to which the bending tool 20 is attached and the two-dimensional movement device to which the support member 21 is attached are different, and the bending tool 20 and the support member 21 perform different movements.

  As a first step, the folding tool 20 approaches the gusset bag 1a at the head of the row horizontally from the left and presses the heading portion 4a. At this time, the support 21 supports one heading portion in the gusset bag arranged behind the head gusset bag 1a, in this case, the root portion of the heading portion 4b of the gusset bag 1b from the right side. The gusset bag 1a is indirectly supported by the support 21 via the gusset bag 1b, and the gusset bag 1a is prevented from falling down due to the pressure of the bending tool 20. Thereby, the bending of the heading part 4a by the bending tool 20 is reliably performed.

  The support member 21 supports the root portion of the heading portion 4b behind the heading portion 4a which is pressed by the bending tool 20 for the following reason. That is, assuming that the base part of the heading part 4a pressed by the bending tool 20 is supported by the supporter 21, when the supporter 21 approaches the heading part 4a, as shown in FIG. 9, the heading part 4b immediately behind is provided. The support 21 may fall to the front side. When the heading part 4a is bent by the bending part 20 on the heading part 4b that has fallen to the front side (see FIG. 10), the heading part 4b is pressed by the heading part 4a and cannot be raised. In order to avoid this, the support member 21 supports the base portion of the heading portion 4b behind it, not the heading portion 4a pressed by the bending tool 20, and the gusset bag 1a is indirectly supported by the support member 21. It is.

  It should be noted that when the support member 21 approaches the heading portion 4b, the support member 21 may naturally tilt the heading portion 4c behind it toward the front side. However, since the heading part 4c tilted to the front side is not pressed by the heading part 4a, the heading part 4c can be lifted if the supporter 21 is raised to go to support the heading part 4c. For this reason, the situation as shown in FIG. 10 does not occur.

  3, the folding tool 20 is further moved horizontally to the right after pressing the heading portion 4a and presses the heading portion 4b as shown in FIG. At this time, the support member 21 changes its position by a so-called gate motion of rising, horizontally moving to the right, and descending, and supports the base portion of the heading portion 4c. Accordingly, the gusset bag 1b is indirectly supported by the support member 21, and the bending of the heading portion 4b by the bending tool 20 is reliably performed.

  In FIG. 4, after the folding head 20b is creased, the bending tool 20 further moves horizontally to the right, and presses the heading 4c as shown in FIG. At this time, the support 21 changes its position by gate motion and supports the root of the heading 4d. Thereby, the gusset bag 1c is indirectly supported by the support member 21, and the bending of the heading portion 4c by the bending tool 20 is reliably performed.

  5, the folding tool 20 further moves horizontally to the right, and presses the heading part 4d supported at the base part by the supporter 21, as shown in FIG. When the folding tool 20 bends the heading part 4d to some extent, a flap folding tool (not shown) bends the inner flap 13 inward so that the heading parts 4a, 4b, 4c and 4d are folded and confined in the box 10. To. The bending tool 20 and the support tool 21 are pulled out instead of being covered with the upper surface inner flap 13 and return to the original position before starting the bending work.

  The upper inner flap 13 is bent until the state shown in FIG. Next, a flap folding tool (not shown) bends the upper outer flap 14 inward to obtain the state shown in FIG. The upper-surface inner flap 13 and the upper-surface outer flap 14 are bonded with a hot melt adhesive, or a sealing tape is applied to the joint of the upper-surface outer flap 14 to complete the packaging by the box 10.

  In the completed packaging, the height of the box 10 is low, and the cost of the box 10 itself is reduced, and distribution costs such as storage and transportation can be reduced. Moreover, since all the heading parts 4 of the gusset bag 1 are bent beautifully to the back side, after unpacking and taking out from the box 10, the heading part 4 in a beautiful state can be shown to the customer.

  9 and 10 can occur when the heading 4 has a certain length (height), and such an event occurs when the heading 4 is short (if low). do not do. If the heading section 4 is short (low) to such an extent that the event shown in FIGS. 9 and 10 does not occur, even the heading section 4 other than the tail end of the row is the root of the heading section 4 itself pressed by the bending tool 20. The part can be supported by the support 21.

  Although the embodiments of the present invention have been described above, the scope of the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the invention.

  INDUSTRIAL APPLICABILITY The present invention can be used for a boxing method for a self-supporting gusset bag and a boxing device for a self-supporting gusset bag used therein.
