JP 2010-64351 A

  In the pasting box manufacturing device of Patent Literature 1, decorative paper extending from the bottom portion is set up, and the extending portion is attached to each outer surface of the cloth box. Then, after the extended portion is attached to the entire outer surface, the folded portion of the decorative paper extending from the upper end of the cloth box is folded and attached to the inner surface of the cloth box. Here, if the width of the folding plate for folding the folded portion into the inside of the fabric box is larger than the width of the side surface of the fabric box, the folded plate contacts the folded portion on the adjacent side surface and damages the decorative paper. The box manufacturing apparatus of Patent Document 1 is provided with a pair of protrusions at both ends of a folding plate so as to sandwich and bend the folded portions of adjacent side surfaces. However, when the bottom surface of the dough box is triangular, rectangular, or the like, that is, when the angle between the adjacent side surfaces is not obtuse, it is not possible to sandwich the folded portion of the adjacent side surface with the protrusion and fold.

  Therefore, when manufacturing a box having an arbitrary polygon including a rectangle as the bottom surface, the width of the folding plate is set smaller than the width of the side surface of the box to be produced. On the other hand, when the width of the folding plate is excessively smaller than the width of the folded portion, the entire folded portion of the decorative paper cannot be pressed, and the folding at both ends becomes insufficient. As a result, when the folded portion is attached to the inner surface of the dough box (at the time of folding), both ends of the folded portion cannot be brought into close contact with the dough box, and a floating occurs between the dough box and the decorative paper. The appearance quality is reduced.

  Therefore, the fold plate needs to be replaced according to the size of the fold box every time the fold box to be produced is changed so that the width of the fold plate is slightly smaller than the side width of the dough box. .

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a box manufacturing apparatus capable of improving productivity by eliminating the need to replace a folding plate.

In order to achieve the above object, a box manufacturing apparatus according to the present invention includes:
A first attaching brush for attaching decorative paper to the side of the dough box,
In a first processing position, a first folding plate that folds a folded portion of the decorative paper stuck by the first sticking brush inside the dough box,
A second attaching brush for attaching the decorative paper to a side surface of the cloth box adjacent to a side surface on which the decorative paper is folded by the first folding plate;
In a second processing position, a second folding plate that folds the folded portion of the decorative paper stuck by the second sticking brush inside the dough box,
An initial position for setting the dough box and the decorative paper; a first processing position; and a suction head for moving the dough box and the decorative paper between the second processing position.
The initial position, the first processing position, and the second processing position are arranged on a straight line,
The second attaching brush,
It is arrange | positioned in the middle of the said 1st processing position and the said 2nd processing position.

Also, the width of the first folding plate is
Larger than the width of the side surface of the suction head on the side where the decorative paper to be folded is attached,
The pushing end of the first folding plate that abuts on the decorative paper and folds the decorative paper is straight.
It may be good.

Further, at least one of the first folding plate and the second folding plate is
It can be adjusted so that the opening direction of the dough box into which the decorative paper is folded and the main surface of the first folding plate or the second folding plate are parallel to each other while rotating about the movable direction as a rotation axis. ,
It may be good.

  According to the present invention, since the folded portion of the decorative box attached to the dough box is folded inside the dough box in a state where the folded portion does not extend from the adjacent side surface, a folding plate larger than the width of the side surface is used. However, the folded plate does not damage the folded portion on the adjacent side surface. Therefore, regardless of the size of the box to be manufactured, a common folding plate can be used, and the productivity can be improved.

  The stage 25 is a flat member on which the cloth box Bb and the decorative paper Dp, which are works, are placed. The stage 25 includes an air suction mechanism (not shown). For example, when folding the folded portions 84 and 86 of the decorative paper Dp, the positions of the cloth box Bb and the decorative paper Dp are changed to the first folding plate 17 and the second folding plate. The plate 18 is held so as not to be displaced. The size of the mounting surface of the stage 25 according to the present embodiment is smaller than the bottom surface of the paste box to be manufactured, and is set so as not to protrude from the bottom surface of the cloth box Bb when the cloth box Bb is mounted. .

  The crimping portions 38 and 39 are members that press the decorative paper Dp stuck to the side surface of the cloth box Bb and crimp the decorative paper Dp. The crimping portion 38 is connected to an air cylinder (not shown) and presses the decorative paper Dp stuck on the long side surface 71 of the cloth box Bb, so that the crimping portion 38 can be moved in the y-axis direction of the stick box manufacturing apparatus 1. (FIG. 8A). Further, the crimping section 39 is connected to an air cylinder (not shown), and moves in the x-axis direction of the box manufacturing apparatus 1 to press the decorative paper Dp stuck on the short side surface 72 of the cloth box Bb. It is arranged as possible (FIG. 8B).

  The control unit 31 includes a CPU, a memory, an external storage device, input / output I / O, and the like, and controls the operation of the entire box manufacturing apparatus 1. Specifically, when the CPU executes a program stored in the external storage device in advance, the control unit 31 sends a control signal to a driver that operates the air cylinders 13, 21, 22, and the like to control the driver. Further, the control unit 31 includes a switch for the operator to turn on / off the power of the box manufacturing apparatus 1 and turn on / off the air.

  Next, a method for manufacturing a box using the box manufacturing apparatus 1 will be described with reference to a flowchart shown in FIG.

  First, as a preparatory work, as shown in FIGS. 2A and 2B, an operator applies an adhesive to the entire sticking surface of the decorative paper Dp cut out according to the size of the cloth box Bb. The bottom surface portion 81 of the decorative paper Dp, which corresponds to the bottom surface of the cloth box Bb, is attached to the bottom surface of the cloth box Bb.

  Subsequently, the worker sets the cloth box Bb and the decorative paper Dp (FIG. 4A) in which only the bottom surface is covered with the decorative paper Dp in the sticker box manufacturing apparatus 1.

  More specifically, when the power supply of the box manufacturing apparatus 1 is turned on, the control unit 31 operates the suction head 12 and the bottom surface of the suction head 12, that is, a surface in the -z direction (hereinafter, referred to as a suction surface). Inhale air from The operator inserts the suction head 12 into the cloth box Bb, and sets the cloth box Bb and the decorative paper Dp (step S11). Thereby, the bottom surface of the dough box Bb is sucked and held on the suction surface of the suction head 12.

  Subsequently, when the first side surface attaching process of the adhesive box manufacturing process is started, the suction head 12 moves down in the −z direction and moves from the initial position to the first processing position. When the suction head 12 is lowered, the first attaching brush 14 arranged in the x-axis direction of the adhesive box manufacturing device 1 comes into contact with the decorative paper Dp.

  The first affixing brushes 14 are opposed to each other at positions where they come into contact with the two long side surfaces 71 of the cloth box Bb sucked by the suction head 12. More specifically, as shown in FIG. 5, the distance Wt1 between the brush tips of the two first attaching brushes 14 is set smaller than the distance Lb2 between the two long side surfaces 71 of the cloth box Bb. The distance Wb1 between the brush base ends of the two first attaching brushes 14 is set to be larger than the distance Lb2 between the two long side surfaces 71 of the cloth box Bb. Thereby, the cloth box Bb and the decorative paper Dp can pass between the two first attaching brushes 14 while being in contact with the tip of the first attaching brush 14.

  As described above, in the process of lowering the suction head 12, the first attaching brush 14 causes the long side surface 82 of the decorative paper Dp extending from the bottom surface of the cloth box Bb to be moved to the long side of the cloth box Bb. It is pasted on the side surface 71 (step S12).

  After the cloth box Bb and the decorative paper Dp pass through the first attaching brush 14, the suction head 12 stops at the first processing position, that is, the position where the cloth box Bb and the decorative paper Dp reach the vicinity of the stage 25. Specifically, the control unit 31 moves the suction head 12 at a position where the bottom surface portion 81 of the decorative paper Dp stuck to the cloth box Bb abuts on the stage 25 or at a position where there is a slight gap, for example, about 1 mm. Stop.

  Subsequently, the control unit 31 stops the air of the suction head 12 and starts suction of the air pipe arranged on the upper surface of the stage 25. As a result, the cloth box Bb and the decorative paper Dp are changed from a state in which they are sucked by the suction head 12 to a state in which they are sucked by the stage 25. Then, the control unit 31 separates the suction head 12 from the cloth box Bb and returns the suction head 12 to the initial position (Step S13).

  Subsequently, the box manufacturing apparatus 1 starts the first folding step. The control unit 31 moves the first folding plate 17 by operating the air cylinder 21 to move the folded portion 84 of the decorative paper Dp extending from the opening end (upper end) of the cloth box Bb to the cloth box. It is folded inside Bb (step S14).

  More specifically, as shown in FIGS. 7A and 7B, the control unit 31 attaches two first folding plates 17 (one of which is omitted in FIGS. 7A and 7B) to the cloth It is moved from the outside of the box Bb to the inside of the cloth box Bb. The lower surface of the two first folding plates 17, that is, the surface in the −z direction is positioned slightly above (+ z direction), for example, about 1 mm above the upper end of the cloth box Bb by adjusting the interval with the stage 25. Is set in advance. As shown in FIG. 7A, the width Lpl of the first folding plate 17 is set to be larger than the width Lbl of the long side surface 71 of the cloth box Bb. Preferably, the width Lpl of the first folding plate 17 is set to be larger than Lblmax, which is the maximum value of the width of the long side surface 71 of the box manufactured by the box manufacturing apparatus 1. The width Lpl of the first folding plate 17 is set to be, for example, about 10 mm larger than Lblmax, which is the maximum value of the width of the long side surface 71. Further, the pushing end portion 17a of the first folding plate 17 that comes into contact with the folding portion 84 and folds the folding portion 84 is linear as shown in FIG. 7A.

  Thus, the first folding plate 17 moves from the outside of the cloth box Bb toward the center of the cloth box Bb in the y-axis direction, and folds the folded portion 84 of the decorative paper Dp into the inside of the cloth box Bb (FIG. C)).

  In the present embodiment, as described above, the decorative paper Dp is not attached to the short side surface 72 of the cloth box Bb when the folded portion 84 extending from the upper end of the cloth box Bb is folded. Therefore, the folded portion 86 of the decorative paper Dp does not extend from the upper end of the short side surface of the cloth box Bb. For this reason, even if the width Lp1 of the first folding plate 17 is set to be larger than the width Lb1 of the long side surface 71, the folded portion 86 of the decorative paper Dp attached to the short side surface 72 will not be damaged. . Accordingly, it is not necessary to replace the first folding plate 17 according to the size of the cloth box Bb, specifically, the width Lb1 of the long side surface 71, and the manufacturing cost of the first folding plate 17 can be reduced. . In addition, the operation cost for replacing the first folding plate 17 can be reduced when the box to be manufactured is switched.

  Subsequently, the control unit 31 lowers the suction head 12 by operating the air cylinder 13 and inserts the suction head 12 into the cloth box Bb. Thus, the folded portion 84 of the decorative paper Dp is folded and attached to the inner surface of the long side surface 71 of the cloth box Bb (step S15). Further, as indicated by the arrow in FIG. 8A, the control unit 31 operates the crimping unit 38 disposed outside the two long side surfaces 71 to press the long side surface 71. Thereby, the decorative paper Dp can be closely adhered to the outer surface and the inner surface of the long side surface 71 of the cloth box Bb. The first folding step according to the present embodiment includes a process of attaching the folded portion 84 to the inner surface of the cloth box Bb.

  Subsequently, the control unit 31 lowers the suction head 12, the stage 25, the cloth box Bb, and the decorative paper Dp in the −z direction, and moves them to the flap folding position. Further, the control unit 31 operates an air cylinder (not shown) to move the four flap brushes 15 toward the center of the cloth box Bb in the y-axis direction or in the + y direction, as indicated by arrows in FIG. -Operate in y direction. Thereby, as shown in FIG. 4D, the flap 83 of the decorative paper Dp extending in the direction of the short side surface 72 (x-axis direction) of the decorative paper Dp attached to the long side surface 71 is removed. It is pasted on the short side surface 72 (step S16).

  The flap brush 15 is disposed at a position where the flap brush 15 is in contact with the two short side surfaces 72 of the dough box Bb adsorbed to the stage 25 so that the longitudinal direction is the z-axis direction. More specifically, as shown in FIG. 6, the distance Wt2 between the brush tips of the two flap brushes 15 on the + x side and the two flap brushes 15 on the −x side is equal to the distance 2 opposite to the opposite side of the cloth box Bb. It is set smaller than the distance Lb1 between the two short side surfaces 72.

  Further, the distance Wb2 between the brush base ends of the two flap brushes 15 on the + x side and the two flap brushes 15 on the -x side is larger than the distance Lb1 between the two short side surfaces 72 of the cloth box Bb. Is set. Therefore, by moving the flap brush 15 in the + y direction or the −y direction, the flap 83 of the decorative paper Dp can be attached to the short side surface 72 of the cloth box Bb.

  Subsequently, the adhesive box manufacturing apparatus 1 starts the second side surface attaching process. The control unit 31 lowers the suction head 12, the stage 25, the cloth box Bb, and the decorative paper Dp in the −z direction, and moves them to the second processing position. When the suction head 12, the stage 25 and the like are lowered, the second sticking brush 16 arranged in the y-axis direction of the stick box manufacturing apparatus 1 comes into contact with the decorative paper Dp.

  The second affixing brushes 16 are opposed to each other at positions where they contact the two short side surfaces 72 of the cloth box Bb. More specifically, similarly to the first attaching brush 14 shown in FIG. 5, the distance between the brush tips of the two second attaching brushes 16 is smaller than the distance between the two short side surfaces 72 of the cloth box Bb. Is set. In addition, the distance between the brush base ends of the two second attaching brushes 16 is set to be larger than the distance between the two short side surfaces 72 of the cloth box Bb. Thereby, the cloth box Bb and the decorative paper Dp can pass between the two second attaching brushes 16 while contacting the tip of the second attaching brush 16.

  As described above, in the process of lowering the suction head 12, the stage 25, and the like to the second processing position, the second attaching brush 16 removes the short side surface portion 85 of the decorative paper Dp extending from the bottom surface of the cloth box Bb. Is attached to the short side surface 72 of the cloth box Bb as shown in FIG. 4E (step S17).

  Subsequently, the control unit 31 operates the air cylinder 13 to return the suction head 12 to the initial position or the first processing position. In the present embodiment, the air cylinder 13 is returned to the initial position.

  In addition, the box manufacturing device 1 starts the second folding process. The control unit 31 moves the second folding plate 18 by operating the air cylinder 22 to fold the folded-back portion 86 of the decorative paper Dp extending from the upper end of the cloth box Bb into the inside of the cloth box Bb. (Step S18).

  More specifically, as shown in FIGS. 9A and 9B, the control unit 31 attaches the two second folding plates 18 (one is omitted in FIGS. 9A and 9B) to the fabric. It is moved from the outside of the box Bb to the inside of the cloth box Bb. The lower surfaces of the two second folding plates 18, that is, the surfaces in the −z direction are slightly above (+ z direction), for example, about 1 mm above the upper end of the cloth box Bb by adjusting the distance from the stage 25. Is set in advance. The width Lp2 of the second folding plate 18 is set to be larger than the width Lb2 of the short side surface 72 of the cloth box Bb, as shown in FIG. 9A. Preferably, the width Lp2 of the second folding plate 18 is set to be larger than Lb2max, which is the maximum value of the width of the short side surface 72 of the box manufactured by the box manufacturing apparatus 1. The width Lp2 of the second folding plate 18 is set, for example, about 10 mm larger than Lb2max, which is the maximum value of the width of the short side surface 72.

  Thereby, the second folding plate 18 moves from the outside of the cloth box Bb toward the center of the cloth box Bb in the x-axis direction, and folds the folded portion 86 of the decorative paper Dp into the inside of the cloth box Bb.

  In the present embodiment, as described above, when the folded portion 86 extending from the upper end portion of the fabric box Bb is folded, the folded portion 84 attached to the long side surface 71 of the fabric box Bb is folded back and the fabric box Bb is folded. Is affixed to the inside of Therefore, the folded portion 84 of the decorative paper Dp does not extend from the upper end of the long side surface of the cloth box Bb. For this reason, even if the width Lp2 of the second folding plate 18 is set to be larger than the width Lb2 of the short side surface 72, the folded portion 84 of the decorative paper Dp attached to the long side surface 71 will not be damaged. . Accordingly, it is not necessary to replace the second folding plate 18 according to the size of the dough box Bb, specifically, the width Lb2 of the short side surface 72, and the manufacturing cost of the second folding plate 18 can be reduced. . In addition, the operation cost for replacing the second folding plate 18 can be reduced when the box to be manufactured is switched. Further, the pushing end portion 18a of the second folding plate 18 which comes into contact with the folding portion 86 and folds the folding portion 86 is linear as shown in FIG. 9A.

  Subsequently, the control unit 31 lowers the suction head 12 by operating the air cylinder 13 and inserts the suction head 12 into the cloth box Bb. Thus, the folded portion 86 of the decorative paper Dp is folded and attached to the inner surface of the short side surface 72 of the cloth box Bb (step S19). Further, as shown by the arrow in FIG. 8B, the control unit 31 operates the crimping unit 39 arranged outside the two short side surfaces 72 to press the short side surface 72, The paste box is completed (FIG. 4 (F)). Thereby, the decorative paper Dp can be closely attached to the outer surface and the inner surface of the short side surface 72 of the cloth box Bb.

  The control unit 31 stops the air of the stage 25 and starts suction of the suction head 12, and causes the completed box to be sucked on the suction surface of the suction head 12. Further, the suction head 12 is returned to the initial position, and the stage 25 is returned to the first processing position.

  The operator stops the air of the suction head 12 and removes the completed box from the suction head 12 (step S20), and the box manufacturing process ends.

  As described above, the box manufacturing apparatus 1 according to the present embodiment attaches the decorative paper Dp to the pair of long side surfaces 71 and then applies the decorative paper Dp to the adjacent short side surfaces 72. Before attaching, the folded portion 84 of the decorative paper Dp is folded inside the cloth box Bb. In other words, the folded portion 84 is folded by the first folding plate 17 before the decorative paper Dp is attached to the adjacent side surface of the cloth box Bb. Therefore, even when the width Lpl of the first folding plate 17 is larger than the width Lbl of the long side surface 71, there is no possibility that the first folded plate 17 comes into contact with the folded portion 86 of the decorative paper Dp attached to the adjacent short side surface 72. Accordingly, it is not necessary to replace the first folding plate 17 according to the width Lbl of the long side surface 71 of the box to be produced, and the common first folding plate 17 can be used, so that productivity is improved. be able to. In addition, the manufacturing cost of the first folding plate 17 can be reduced, and the operation cost of replacing the second folding plate 18 when switching the box to be manufactured can be omitted.

  Further, the pushing end portion 17a of the first folding plate 17 is straight, and a box having an arbitrary polygonal bottom surface such as a triangle and a rectangle can be manufactured without replacing the first folding plate 17.

  Further, by using the first folding plate 17 having a width larger than the folded portion 84 and the second folding plate 18 having a width larger than the folded portion 86, the folded portions 84 and 86 can be folded while being pressed down to both ends in the width direction. Therefore, the adhesiveness between the cloth box Bb and the decorative paper Dp can be enhanced, and the appearance quality of the box can be improved.

  In the pasting box manufacturing apparatus 1 according to the present embodiment, the initial position, the first processing position, the flap folding position, and the second processing position for setting the cloth box Bb and the decorative paper Dp, which are the works, are arranged on a straight line. ing. Thus, the suction head 12 and the stage 25 can be moved only by the direct actuator, so that the structure of the box manufacturing apparatus 1 can be simplified.

  In the present embodiment, the long side surface 71 of the cloth box Bb is arranged parallel to the xz plane, and the short side surface 72 is arranged parallel to the yz plane. However, the present invention is not limited to this. The side surface 71 and the short side surface 72 may be replaced with each other. Further, the bottom surface of the dough box Bb according to the present embodiment is rectangular, but is not limited to this. For example, squares having the same side length may be used.

  Further, the shape of the bottom surface of the dough box Bb is not limited to a square, and may be, for example, a hexagon, an octagon, or the like. In this case, every other side surface to which the decorative paper Dp is attached at the first processing position may be set, and the decorative paper Dp may be attached to the adjacent side surface at the second processing position.

  Further, in the present embodiment, the operation of attaching the decorative paper Dp to the side surface of the dough box Bb is performed at the two processing positions of the first processing position and the second processing position. May be provided. Thus, in two processing positions such as a pentagon and a heptagon, even if it is difficult to attach the decorative paper Dp to the adjacent side surfaces in a separate process, leave the adjacent side surfaces open and apply the decorative paper Dp. Can be attached. Thereby, the first folding plate 17 and the second folding plate 18 having a width larger than the width of the dough box Bb can be used. Therefore, the box can be manufactured without replacing the first folding plate 17 and the second folding plate 18 according to the size of the box to be produced.

  Further, in the present embodiment, the first folding plate 17 protrudes from both ends in the width direction of the long side surface 71 of the cloth box Bb, but the present invention is not limited to this. For example, as shown in FIG. 10, the first folding plate 17 may be arranged such that one end thereof is inside the width (x-axis direction) of the long side surface 71. In this case, the cloth box Bb and the decorative paper Dp, which are works, are based on the end of the width direction both ends of the cloth box Bb on the side where the first folding plate 17 is located inside (−x side in FIG. 10). May be set in the box manufacturing apparatus 1. Thereby, even if the size of the box to be manufactured changes, it is possible to fold the folded box 84 while holding down the entire width of the folded section 84 in the width direction.

  In the present embodiment, the first folding plate 17 is fixed such that the bottom surface of the dough box Bb and the main surface of the first folding plate 17 are parallel, but the present invention is not limited to this. For example, the first folding plate 17 may be configured to be rotatable around a movable direction (y-axis direction) of the first folding plate 17 when folding the decorative paper Dp. Although the angle adjusting means is not particularly limited, for example, the angle at which the first folding plate 17 is attached to the air cylinder 21 can be adjusted around a screw for fixing the first folding plate 17 to the air cylinder 21.

  As a result, as shown in FIGS. 11A and 11B, the opening end (the edge of the opening) of the dough box Bb into which the folded-back portion 84 is folded and the main surface of the first folding plate 17 are parallel. Can be adjusted in advance so that Therefore, the decorative paper Dp can be folded with high quality even in the case Bb whose opening end is not parallel to the bottom surface.

  Further, similarly to the above-described first folding plate 17, the angle of the second folding plate 18 may be adjustable. This allows the decorative paper Dp to be folded in the second folding step at the opening end that is not parallel to the bottom surface of the cloth box Bb.

(Embodiment 2)
Subsequently, a box manufacturing apparatus 2 (FIG. 12) according to Embodiment 2 of the present invention will be described. The box manufacturing apparatus 2 according to the present embodiment is different from the first embodiment in that decorative paper Dp extending both above and below the cloth box Bb is folded. More specifically, the processing position at which the decorative paper Dp extending from the upper end and the lower end of the long side surface 71 of the cloth box Bb is set as the first processing position, and the upper and lower ends of the short side surface 72 of the cloth box Bb are set. The processing position at which the decorative paper Dp extending from is folded is defined as a second processing position. Other configurations are the same as those of the first embodiment, and therefore are denoted by the same reference numerals.

  In the box manufacturing apparatus 2 according to the present embodiment, as shown in FIGS. 13A and 13B, a work in which decorative paper Dp is stuck on the entire side surface of the cloth box Bb is used.

  Hereinafter, a method for manufacturing a box using the box manufacturing apparatus 2 will be described with reference to a flowchart shown in FIG.

  First, as a preparation work, as shown in FIGS. 13A and 13B, an operator applies an adhesive to the entire sticking surface of the decorative paper Dp cut out according to the size of the cloth box Bb. Then, the decorative paper Dp is attached so as to be wound around the entire side surface of the cloth box Bb. The cloth box Bb according to the present embodiment has a rectangular bottom surface, two long side surfaces 71, and two short side surfaces 72, as in the first embodiment, and has an open top surface.

  Subsequently, the worker sets the cloth box Bb and the decorative paper Dp (FIG. 15 (A)) whose side surfaces are covered with the decorative paper Dp in the adhesive box manufacturing apparatus 2. More specifically, when the power supply of the box manufacturing apparatus 2 is turned on, the control unit 31 operates the suction head 12 to suck air from the bottom surface (suction surface) of the suction head 12. The operator inserts the suction head 12 into the cloth box Bb, and sets the cloth box Bb and the decorative paper Dp (step S31). Thereby, the bottom surface of the dough box Bb is sucked and held on the suction surface of the suction head 12.

  Subsequently, the suction head 12 moves down in the −z direction and moves from the initial position to the first processing position (Step S32). At the first processing position, as shown in FIG. 16A, the control unit 31 performs suction at a position where the bottom surface of the dough box Bb is slightly higher than the upper surface of the first folding plate 17, for example, about 1 mm. The head 12 is stopped.

  Subsequently, the box manufacturing apparatus 2 starts the first folding step. The control unit 31 operates the air cylinder 21 to move the first folding plate 17 to fold the folded portion 92 of the decorative paper Dp extending from the bottom surface of the cloth box Bb into the inside of the cloth box Bb. (Step S33).

  More specifically, the control unit 31 moves the two first folding plates 17 from outside the cloth box Bb to inside the cloth box Bb, as indicated by arrows in FIG. The upper surfaces of the two first folding plates 17, that is, the surfaces in the + z direction are preset so as to be located slightly below (−z direction) from the bottom surface of the cloth box Bb as described above. Further, the width of the first folding plate 17 is set smaller than the width of the long side surface 71 of the cloth box Bb. Further, the pushing end portion 17a of the first folding plate 17 which comes into contact with the folding portion 92 and folds the folding portion 92 has a linear shape as in the first embodiment.

  Accordingly, the first folding plate 17 moves from the outside of the cloth box Bb toward the center of the cloth box Bb in the y-axis direction, and folds the folded portion 92 of the decorative paper Dp toward the center of the bottom surface of the cloth box Bb ( FIG. 15 (B).

  As shown in FIGS. 16A and 16C, the upper surfaces of the first folding plate 17 and the second folding plate 18, that is, the surfaces facing the + z direction in the state where they are arranged in the box manufacturing device 2, The side that contacts the decorative paper Dp is chamfered. Thus, when folding the decorative paper Dp into the bottom surface of the cloth box Bb, it is possible to suppress the first folding plate 17 and the second folding plate 18 from being caught on the decorative paper Dp and damaging the decorative paper Dp. The pushing ends 17a and 18a have an R-shaped cross section. Thereby, the frictional resistance between the first folding plate 17 and the second folding plate 18 and the decorative paper Dp can be reduced. The lower surfaces of the first folding plate 17 and the second folding plate 18 are chamfered in the same manner as in the first embodiment.

  Subsequently, the suction head 12 descends in the -z direction, and moves from the first processing position to the second processing position (Step S34). At the second processing position, the control unit 31 stops the suction head 12 at a position where the bottom surface of the dough box Bb is slightly above the upper surface of the second folding plate 18, for example, about 1 mm (see FIG. )).

  Then, the box manufacturing apparatus 2 starts the second folding step. The control unit 31 moves the second folding plate 18 by operating the air cylinder 22 to move the folding unit 95 of the decorative paper Dp extending from the bottom of the cloth box Bb toward the center of the bottom of the cloth box Bb. (Step S35). The folded portion 95 is a portion extending from the side surface adjacent to the side surface where the folded portion 92 is folded in the first folding process to the bottom surface side.

  More specifically, the control unit 31 moves the two second folding plates 18 from outside the cloth box Bb to inside the cloth box Bb. The upper surfaces of the two second folding plates 18, that is, the surfaces in the + z direction are preset so as to be located slightly below (−z direction) from the bottom surface of the cloth box Bb as described above. The width Lp2 of the second folding plate 18 is set to be larger than the width Lb2 of the short side surface 72 of the cloth box Bb, as in the first embodiment (FIG. 9A). Further, the pushing end portion 18a of the second folding plate 18 which comes into contact with the folding portion 95 and folds the folding portion 95 is linear as in the first embodiment.

  Thereby, the second folding plate 18 moves from the outside of the cloth box Bb toward the center of the cloth box Bb in the x-axis direction, and folds the folded part 95 of the decorative paper Dp into the bottom part of the cloth box Bb (FIG. 15). (C)).

  Subsequently, the controller 31 lowers the suction head 12. The control unit 31 moves the suction head 12 at a position where the folding units 92 and 95 of the decorative paper Dp folded on the bottom surface of the dough box Bb abut on the stage 25 which is previously arranged below the second processing position. Stop. Thus, the folded portions 92 and 95 of the decorative paper Dp can be brought into close contact with the bottom surface of the cloth box Bb.

  The control unit 31 stops the air of the suction head 12 and starts sucking the air pipe disposed on the upper surface of the stage 25. As a result, the cloth box Bb and the decorative paper Dp are changed from a state in which they are sucked by the suction head 12 to a state in which they are sucked by the stage 25. Then, the control unit 31 removes the suction head 12 from the cloth box Bb and returns the suction head 12 to the initial position. Further, the controller 31 raises the stage 25, the cloth box Bb and the decorative paper Dp that are attracted to the stage 25 in the + z direction, and moves them to the first processing position (step S36).

  At the first processing position, the control unit 31 determines that the opening end (upper end) of the cloth box Bb is slightly lower than the lower surface of the first folding plate 17, for example, about 1 mm, as shown in FIG. The stage 25 is stopped at the position where.

  Subsequently, the box manufacturing apparatus 2 starts the third folding step. The control unit 31 operates the air cylinder 21 to move the first folding plate 17 and fold the folded-back portion 93 of the decorative paper Dp extending from the upper end of the cloth box Bb into the inside of the cloth box Bb. (Step S37).

  More specifically, the control unit 31 moves the two first folding plates 17 from outside the cloth box Bb to inside the cloth box Bb, as indicated by arrows in FIG. 16C. The lower surfaces of the two first folding plates 17, that is, the surfaces in the −z direction are preset so as to be located slightly above (+ z direction) from the upper end of the cloth box Bb as described above. Then, the first folding plate 17 moves from the outside of the cloth box Bb toward the center of the cloth box Bb in the y-axis direction, and folds the folded portion 93 of the decorative paper Dp into the inside of the cloth box Bb (see FIG. )).

  Subsequently, the control unit 31 lowers the suction head 12 by operating the air cylinder 13 and inserts the suction head 12 into the cloth box Bb. Thus, the folded portion 93 of the decorative paper Dp is folded and attached to the inner surface of the long side surface 71 of the cloth box Bb as shown in FIG. 15E (step S38). Further, similarly to the first embodiment, the control unit 31 operates the crimping unit 38 disposed outside the two long side surfaces 71 to press the long side surface 71. Thereby, the decorative paper Dp can be closely adhered to the outer surface and the inner surface of the long side surface 71 of the cloth box Bb. The third folding step according to the present embodiment includes a process of attaching the folded portion 93 to the inner surface of the cloth box Bb.

  Subsequently, the controller 31 lowers the stage 25, the cloth box Bb, and the decorative paper Dp in the −z direction and moves them to the second processing position (Step S39).

  At the second processing position, the control unit 31 determines that the opening end (upper end) of the cloth box Bb is slightly lower than the lower surface of the second folding plate 18, for example, about 1 mm, as shown in FIG. The stage 25 is stopped at the position where.

  Subsequently, the box manufacturing apparatus 2 starts the fourth folding step. The control unit 31 moves the second folding plate 18 by operating the air cylinder 22 to fold the folded-back portion 96 of the decorative paper Dp extending from the upper end of the cloth box Bb into the inside of the cloth box Bb. (Step S40). The folded portion 96 is a portion extending from the side surface adjacent to the side surface where the folded portion 93 is folded in the third folding process to the opening end.

  More specifically, the control unit 31 moves the two second folding plates 18 from outside the cloth box Bb to inside the cloth box Bb. The lower surfaces of the two second folding plates 18, that is, the surfaces in the −z direction are preset so as to be located slightly above (+ z direction) from the upper end of the cloth box Bb as described above.

  Accordingly, the second folding plate 18 moves from the outside of the cloth box Bb toward the center of the cloth box Bb in the x-axis direction, and folds the folded portion 96 of the decorative paper Dp into the inside of the cloth box Bb (FIG. F)).

  Subsequently, the control unit 31 operates the air cylinder 13 to lower the suction head 12 and insert the suction head 12 into the cloth box Bb. Thus, the folded portion 96 of the decorative paper Dp is folded and attached to the inner surface of the short side surface 72 of the cloth box Bb as shown in FIG. 15 (G) (step S41). Further, similarly to the first embodiment, the control unit 31 operates the crimping unit 39 disposed outside the two short side surfaces 72 to press the short side surface 72. Thus, the decorative paper Dp can be brought into close contact with the outer surface and the inner surface of the short side surface 72 of the cloth box Bb. The fourth folding step according to the present embodiment includes a process of attaching the folded portion 96 to the inner surface of the cloth box Bb.

  The control unit 31 stops the air of the stage 25 and starts suction of the suction head 12, and causes the completed box to be sucked on the suction surface of the suction head 12. Further, the suction head 12 is returned to the initial position.

  The operator stops the air of the suction head 12 and removes the completed box from the suction head 12 (step S42), and the box manufacturing process ends.

  As described above, the box manufacturing apparatus 2 according to the present embodiment extends the decorative paper Dp extending downward (bottom side) from the side surface of the cloth box Bb and extending upward (upper end side). The decorative paper Dp is folded by a common first folding plate 17 and second folding plate 18. Therefore, it is not necessary to use different devices for the upper folding process and the lower folding process. Further, since the upper folding process and the lower folding process are switched depending on the positions of the suction head 12 and the stage 25, the position adjustment of the folding plate is unnecessary.

  Further, since the width Lp2 of the second folding plate 18 is set to be larger than the width Lb2 of the short side surface 72 of the cloth box Bb, the width Lp2 of the short side surface 72 of the box to be produced is adjusted to the second width Lp2. There is no need to replace the folding plate 18, and a common second folding plate 18 can be used. Therefore, productivity can be improved. In addition, the manufacturing cost of the second folding plate 18 can be reduced, and the operation cost of replacing the second folding plate 18 at the time of switching the box to be manufactured can be omitted.

  In the present embodiment, the decorative paper Dp is attached to the entire periphery of the side surface of the cloth box Bb, but the present invention is not limited to this. For example, the decorative paper Dp may be attached to both one of the two long side surfaces 71 and the two short side surfaces 72.

  Further, in the present embodiment, the first attaching brush 14, the second attaching brush 16, and the like are not provided, but the present invention is not limited to this. By providing these brushes, it is also possible to manufacture the pasting box described in the first embodiment, that is, the pasting box in which the decorative paper Dp is pasted on the bottom surface and then the decorative paper Dp is pasted on the side surface.

  Further, in the box manufacturing apparatus 2 according to the present embodiment, the initial position, the first processing position where the first folding step and the third folding step are performed, and the second processing where the second folding step and the fourth folding step are performed. The positions are arranged on a straight line. Thus, the suction head 12 and the stage 25 can be moved only by the straight-line actuator, so that the structure of the box manufacturing apparatus 2 can be simplified.
