  1 and 2 show a preferred embodiment of a box making apparatus according to the present invention. The box making apparatus 10 according to the present embodiment is made by appropriately folding the unfolded blank carton 1 and opening it in an upper opening state. After packing a plurality of sheet-like articles from the opening, Close the box and complete the box making process.

  In the blank carton 1, for example, as shown in FIG. 3A, a first side wall 1 b and a second side wall 1 c are connected to two opposing long sides of a rectangular bottom 1 a, and two short sides of the bottom 1 a are opposed to each other. The third lower side wall 1d and the fourth lower side wall e are connected to each other. A lid 1f is connected to the long side of the second side wall 1c that is not connected to the bottom 1a. A narrow lid stopper flap 1n is connected to the long side of the lid portion 1f that is not connected to the second side wall 1c, and the third upper side wall 1g and the fourth upper side wall are connected to the two short sides of the lid portion 1f. 1h is connected. Further, adhesive margin flaps 1i, 1j, 1k, 1m are connected to the short sides of the first and second side walls 1b, 1c.

  On the other hand, the sheet-like article 2 is a package in which a plurality of syringes are blister packed as shown in FIG. This article 2 takes a form in which the opening side of a container film 3 having a semi-cylindrical recess 3 a is closed with a lid film 4. A syringe is accommodated in the recess 3a. Since one side is convex, a plurality of pairs of a set of articles in which two articles are stacked so that the pocket portions 3a face each other are stacked.

  As shown in FIGS. 1 and 2, the box making apparatus 10 includes a first robot 11 and a second robot 12. The first and second robots 11 and 12 are articulated robots and perform predetermined operations in accordance with instructions from the control panel 19. Details of this operation will be described later.

  The hand portion 14 provided at the tip of the robot arm 13 includes a mold 15 and a suction pad 16 attached in front of a rectangular box-shaped base box 28. The suction pad 16 is moved forward and backward by a suction pad cylinder 17 installed in the base box 28, and takes an operating position protruding outside the mold 15 and a standby position entering the back side of the mold 15. As shown in enlarged views in FIGS. 10 and 11, the suction pad 16 is mounted on the moving plate 24 attached to the tip of the cylinder rod 17 a of the suction pad cylinder 17 disposed in the mold 15. A front plate 25 is attached to the front side of the moving plate 24 at a predetermined distance, and the suction pad 16 projects forward through through holes 25 a formed at four corners of the front plate 25.

  The suction pad 16 at the operating position protrudes forward from the mold 15 in a state where it is not sucked, but the suction pad 16 is also in contact with the blank carton 1 and sucked. The front end of the shrink mold 15 comes into contact with the blank carton 1.

  Further, the hand unit 14 has a mold 15 attached in front of a rectangular box-shaped base box 28 connected to the tip of the robot arm 13. The mold 15 is composed of four guide plates. That is, the fixed guide plate 31 fixed to one side of the base box 28, the first moving guide plate 32 disposed on the opposite side of the fixed plate 31, and the second and third guides disposed on the remaining two sides. Plates 33 and 34 are provided. The first, second, and third moving guide plates 32, 33, and 34 arranged on the other three sides are first, second, and third guide plate cylinders 36 that are installed at predetermined positions on the front plate 25. , 37, 38, and moves away from and approaches the center of the front plate 25 according to the reciprocating motion of the cylinder. As a result, the distance between the opposing guide plates changes.

  The first robot 11 takes out one by one from the lowermost end of the blank carton 1 set in a stacked state in the carton magazine 20 disposed on the upstream side. That is, as shown in FIG. 2, the carton magazine 20 is set by being sandwiched between a support member that protrudes inward from the frame body 21 and a holding plate 22 that moves up and down along the guide rail 23. Therefore, the bottom 1a of the blank carton 1 exposed at the lowermost end is sucked and held in a state where the suction pad cylinder 17 is moved forward so that the suction pad 16 protrudes outward from the tip of the mold 15. 1 The robot arm 13 of the robot 11 is moved along a predetermined trajectory, and the hand unit 14 faces downward to face the table 40. The table 40 is a flat table having an outer dimension wider than that of the unfolded blank carton 1, and the first robot arm 11 places the blank carton 1 on the table 40 while holding the blank carton 1 by suction. It moves horizontally to the position of the female mold 45 that becomes the box making section. More specifically, the bottom portion 1a that is sucked and held by the hand portion 14 (suction pad 16) moves up to the upper side of the female mold 45, where the horizontal movement is stopped.

  Carton restraining plates 41 are disposed above the left and right sides of the carry-out side (box making unit side) of the table 40. The tips of the third lower side wall 1d, the fourth lower side wall e, the third upper side wall 1g, and the fourth upper side wall 1h of the horizontally moving blank carton 1 pass through the gap between the table 40 and the carton holding plate 41. pass.

  Gluing devices 42 are provided on both sides of the conveyance path from the table 40 to the female mold 45. In the gluing device 42, glue is jetted from an upward jet nozzle 42a. This injection is performed for a certain period of time in synchronization with the movement of the blank carton 1, and the glues a, b, c, and d adhere to predetermined positions on the lower surfaces of the adhesive margin flaps 1 i, 1 j, 1 k, and 1 m during the movement. Since the glue is jetted in synchronism with the movement of the blank carton in this way, the gluing device 42 is an area having a predetermined length as shown in FIG. 3 only by jetting from the jet nozzle 42a at the same position without moving. Can be attached.

  The female die 45 has an inner shape dimension that is substantially the same as the outer dimension of the bottom portion 1a of the blank carton 1 but is slightly larger, and a plurality of first rollers 46 are vertically arranged at portions facing the pair of long sides of 1a. A plurality of second rollers 47 are arranged vertically on one short side of the bottom portion 1a (connection portion with the third lower side wall 1d), and the other short side (fourth lower side wall 1e) of the bottom portion 1a. A plurality of third rollers 48 are arranged at the top and bottom of the connection part). Each of the rollers 46, 47, and 48 is a free roller and rotates at the place where it is installed, and the rotation axis is parallel to each side. Furthermore, the upper opening 45a of the female mold 45 is formed with a tapered surface that spreads outward. Guided by this taper surface, each side wall of the blank carton 1 enters the female mold 45 while rising smoothly. Further, a carton sag prevention plate 52 that is raised and lowered by the cylinder 53 is disposed in the upper opening 45a. The tip of the carton sag prevention plate 52 is located below the taper surface in the lowered position, and the upper end of the female die 45 as shown by the solid line in FIG. It reaches on the extension line. Thus, at the beginning of the insertion of the blank carton 1 into the female mold 45, the carton sag prevention plate 52 is positioned at the lowered position, and the third and fourth lower side walls 1d and 1e are formed along the tapered surface in the second and third directions. The rollers 47 and 48 are reached. When the carton sag prevention plate 52 is positioned at the rising position at an appropriate timing, the carton is prevented from sagging along the taper surface, and the carton is erected vertically.

  On the other hand, in the mold 15 of the hand portion 14 of the first robot 11, the movement guide plates 32, 33, and 34 all move to the center side, and the fixed guide plate 31 and the first to third movement guide plates 32 to 34. The external dimensions of the square mold formed by the two guide plates are the smallest. The external dimensions are set to be approximately equal to or slightly smaller than the size and shape of the bottom 1a of the blank carton 1. And when adsorb | sucking the bottom part 1a of the blank carton 1 with the suction pad 16, 4 sides (each guide plates 31-34) of the mold 15 are made to follow 4 sides of the bottom part 1a. As a result, the outer dimension of the mold 15 is set slightly smaller than the inner dimension of the female mold 45, and the mold 15 functions as a male mold corresponding to the female mold 45.

  Therefore, when the hand part 14 is moved downward by the robot arm 13 of the first robot 11 with the bottom 1a of the blank carton positioned on the female mold 45, the four sides of the bottom 1a come into contact with the tip of the formwork 15. Since the blank carton 1 is inserted into the female mold 45 in a restrained state, the first side wall 1b and the second side wall 1c are guided by the first roller 46, and the third lower side wall 1d is guided by the second roller 47. The fourth lower side wall 1e rises while being guided by the third roller 48.

  At this time, since the first roller 46 is disposed from above the second and third rollers 47 and 48, the first and second side walls 1b and 1c rise first, and then the third and third The fourth lower side walls 1d and 1e rise. Further, when the first and second side walls 1b, 1c are raised by a known folding mechanism, the adhesive margin flaps 1i, 1j, 1k, 1m are also bent inward. Therefore, the adhesive margin flaps 1i, 1j, 1k, and 1m are bent first, and then the third and fourth lower side walls 1d and 1e rise, so that the adhesives a, b, c, and d are attached. The outer surfaces of the adhesive margin flaps 1i, 1j, 1k, and 1m are positioned inside the third and fourth lower side walls 1d and 1e, and are in contact with the inner surfaces of the third and fourth lower side walls 1d and 1e to be glued. The In FIG. 3, reference symbols a ′, b ′, c ′, and d ′ are portions that are glued with glues a, b, c, and d.

  The cylinder 50 is linked to the support plate 54 on which the third roller 48 is supported by bearings, and moves in parallel along the axis of the third roller 48 as the cylinder 50 reciprocates. This movement is guided by the guide rod 51 and performed in a stable posture. As described above, the third roller 48 constitutes one surface of the female die 45 and performs the process of raising the fourth lower side wall 1e. Thus, the cylinder 50 operates from the state of functioning as a mold, and the third roller 48 is shifted from the one surface of the female die 45 to the open state. When opened in this way, the box made from the open part can be carried out of the female mold 45.

  The box making process using the female mold 45 and the hand part 14 (male mold 15) in the box making section is as shown in FIGS. First, as shown in FIG. 14A, one blank carton 1 sucked by the suction pad 16 is moved to a position above the female mold 45. In FIG. 14A, the third roller 48 is not shown.

  Next, the mold 15 is moved down while the blank carton 1 (bottom) is sucked by the suction pad 16. As a result, the first side wall 1b, the second side wall 1c, the third lower side wall 1d, and the fourth lower side wall 1e are raised and the adhesive margin flaps 1i, 1j, 1k, 1m are bent, and the adhesive margin flaps 1i, 1j, 1k are bent. , 1m are bonded to the third lower side wall 1d and the fourth lower side wall 1e (see FIG. 14B). Thereby, intermediate box 1 'is completed.

  FIG. 14C is a diagram in which the illustration of the hand portion (the mold 15 and the suction pad 16) is omitted in the step shown in FIG. 14B, and a third roller 48 is added. FIG. 14 (b) ′ is a view of the state of FIG. 14 (b) viewed from a direction different by 90 degrees. Even in the state of FIG. 14 (c), the suction pad 16 holds the bottom 1a of the blank carton 1 (intermediate box 1 ') by suction, so that the hand part 14 is raised by a predetermined amount from this state. The amount of increase is at least as shown in FIGS. 14D and 14D ′ until the uppermost third roller 48 comes into contact with the fourth lower side wall 1e.

  Next, in this state, the cylinder 50 is operated to move the third roller 48, and the female third lower side wall 1e side is opened (FIGS. 15A and 15A '). Since the third rollers 48 (two in the example in the figure) that are in contact with the intermediate box 1 'are in contact with the fourth lower side wall 1e, the fourth lower side wall is always in motion during the movement of the third roller 48. The state in contact with 1e is maintained, after which it is detached from the intermediate package 1 '. Therefore, smooth movement can be guaranteed. On the other hand, if the third roller 48 is suddenly moved from the state shown in FIG. 14C, for example, the third roller that has been in contact with the adhesive margin flap 1m (the uppermost portion on the right side in the drawing) is temporarily used as an adhesive margin. After separating from the flap 1m, after moving through the space between the adhesive margin flaps 1m, 1j, it comes into contact with the adhesive margin flap 1j again. At the time of this contact, the third roller 48 may collide with the end surface of the adhesive margin flap 1j, and the surface of the adhesive margin flap 1j may not be smoothly transferred, or the adhesive margin flap 1j may be damaged.

  If the third roller 48 is separated and opened, then the hand unit 14 is moved downward again and lowered to the bottom ((FIGS. 15 (b) and (b) '). It is carried out from the opened side (the portion where the third roller 48 was present) (FIG. 15 (c) ′).

  A conveyance path 60 is provided on the carry-out side of the female mold 45. This conveyance path 60 is for conveying the intermediate box body 1 'opened upward in the box making section. The conveyance finger 60 contacts and pushes the side surface of the intermediate box body 1' and the pushing finger. A driving device 62 for reciprocating 61 is provided. The pushing finger 61 temporarily stops at a product supply position indicated by a solid line in FIG. 2 and an intermediate box unloading position indicated by a two-dot chain line in FIG.

  In order to transfer the intermediate box in the female mold 45 to the conveyance path 60, for example, the first robot 11 may be used, or various methods may be employed such as extrusion with a pusher driven by a cylinder or the like. Furthermore, the moving range of the pushing finger 61 may be extended so that the pushing finger 61 itself enters the female mold 45 and carries out the intermediate box 1.

  The second robot 12 is installed on the opposite side of the first robot 11 with the conveyance path 60 in between. The second robot 12 receives the articles 2 transported in two rows by the article transport conveyor 66, and stacks and supplies them to the intermediate box 1 '. The article transporting conveyor 66 is a belt conveyor device, and in one row, the pocket portion 3a is transported in the upper posture, and in the other row, the pocket portion 3a is transported in the lower posture.

  When the supply of a predetermined number of articles 2 into the intermediate box 1 'is completed by the second robot 12, the feeding finger 61 that has been temporarily stopped restarts, and the intermediate box 1' is brought to the intermediate box unloading position. Transport. In the middle of this transfer, the glue e is attached to a predetermined position above the first side wall 1b by a gluing device 65 provided at a predetermined position on the article conveying conveyor 66 side of the conveying path 60. Since the pasting process by the pasting device 65 is also performed during the movement of the intermediate box 1 ', pasting can be performed on a long region simply by spraying the pasting from the pasted pasting device 65.

  Next, the robot arm 13 of the first robot 11 moves along a predetermined path, and the lid 15 is closed by appropriately operating the mold 15 and the suction pad 16. That is, as shown in FIGS. 16 (a) and 16 (a) ′, the intermediate box 1 ′ has the mold 15 attached to the lid 1f in a state where the lid 1f and the like stand up on the second side wall 1c. It approaches the lid 1f from the outside. In addition, Fig.16 (a) 'is the figure which looked at Fig.16 (a) from the left. Further, the suction pad 16 is at a standby position deep in the mold 15. At this time, the mold 15 is in an open state, that is, a state in which the distance between the opposing guide plates is widened.

  In this state, the mold 15 moves horizontally to contact the lid portion 1f to bend the lid portion 1f, and accordingly, the third upper side wall 1g, the fourth upper side wall 1h, and the lid stopper flap 1n connected to the lid portion 1f. Also fall down together (FIGS. 16B and 16B). In the figure, the lid 1f and the like are in a state of being inclined 45 degrees.

  Next, the mold 15 is also tilted in accordance with the tilt of the lid 1f and the like, and the tip of the mold 15 contacts the periphery of the lid 1f (FIG. 16C). The mold 15 suppresses the lid 1f and the like while correcting the inclination of the mold 15 in accordance with the inclination of the lid 1f, and the lid 1f is leveled as shown in FIGS. 17 (a) and 17 (a) ′. Further, the first, second, and third guide plate cylinders 36, 37, and 38 are moved forward at a predetermined timing to separate the first, second, and third movable guide plates 32, 33, and 34 (FIG. 12, In FIG. 13, the position indicated by the two-dot chain line) is expanded. As a result, the inner shape and shape of the mold 15 is made slightly larger than the outer dimension of the intermediate box 1 ', and the mold 15 functions as a female mold.

  As described above, since the inner diameter of the mold 15 is slightly larger than the outer dimension of the intermediate box 1 ', the mold 15 is gradually moved downward from the state shown in FIGS. 17 (a) and 17 (a)'. The lid stopper flap 1n, the third upper side wall 1g, and the fourth upper side wall 1h are pushed down by the mold 15 (FIGS. 17B and 17B), and finally the inner peripheral surface of the mold 15 Then, it is sandwiched and folded between the intermediate box (FIGS. 17B and 17B).

  Adhesive e is applied above the first side wall 1b facing the lid flap 1n (see FIG. 16 and the like). Therefore, the lid flap 1n and the first side wall 1b are bonded using the glue e. Specifically, as shown in FIGS. 18A and 18A ′, the suction pad 70 is brought into contact with the first side wall 1b to be sucked and pulled outward in this state. Then, the 1st side wall 1b moves outside. Since the mold 15 exists outside the lid flap 1n, it does not move further outside. Therefore, adhesion by glue e is performed. Further, at this time, the first moving guide plate cylinder 36 may be moved backward to move the first moving guide plate 32 toward the center of the mold. As a result, the interval between the first moving guide plate 32 and the fixed guide plate 31 is shortened, and the lid stopper flap 1n is pushed toward the first side wall 1b, so that it is more reliably bonded.

  Next, after the mold 15 is raised and separated from the intermediate box 1 'and the suction pad 16 is protruded outside the mold 15, the lid 1f is sucked by the suction pad 16 (FIG. 18B). ), (B) ′). Since the lid flap 1n and the first side wall 1b are bonded in the previous step, the lid 1c is closed, but the third upper side wall 1g and the fourth upper side wall 1h are in a free state although they are folded. So it opens again. The bending of the third upper side wall 1g and the fourth upper side wall 1h may not be performed here.

  When the robot arm 13 and the hand unit 13 are moved in a state where the lid portion 1f is sucked by the suction pad 16, the intermediate box 1 'also moves following the movement. Therefore, the intermediate box 1 'on the transport path 60 is moved on the transport path 69 toward the carry-out conveyor 67 side. During this movement, the glues f and h are attached to the upper side of the third and fourth lower side walls 1d and 1e by the pair of right and left gluing devices 68 (FIG. 18C, FIG. 19A and FIG. 19A). . This gluing process is also performed while the first robot 11 is moving while adsorbing the intermediate box 1 '.

  Thereafter, the third and fourth upper side walls 1g and 1h are folded and bonded with glues f and h (FIGS. 19B and 19B). This folding process is performed by sandwiching the mold 15 released from the suction by the suction pad 16 between the second and third movement guide plates 33 and 34. Adhesion is performed by being suppressed from both sides by a pushing member such as a pusher that operates with cylinders arranged on the left and right sides of the transfer conveyance path 69. Thereby, the packaging box 1 ″ is completed.

  Note that 1 g and 1 h are not suppressed from both sides by a separately prepared push member such as a pusher as described above, but, for example, the suction pad is placed on the back side of the mold 15 in the same manner as the lid closing step shown in FIG. The formwork 15 that has moved and opened is placed on the intermediate box 1 ′, moved downward further than the state of FIG. 18 (a), and the second and third movement guide plates 33 and 34 are moved downward. The lower part reaches the adhesion position of the glues f and h, and in this state, the distance between the second and third movement guide plates 33 and 34 is narrowed so that the third and fourth upper side walls 1g and 1h are entirely sandwiched and bonded. You may make it do. If it does in this way, pushing members, such as a pusher, will become unnecessary and all the sealing can be performed with a robot hand.

  After that, as shown in FIGS. 19C and 19C ′, the side surface of the packaging box 1 ″ is pushed by the side surface of the mold 15 and supplied onto the carry-out conveyor 67 formed of a free roller conveyor. The packaging box body 1 ″ is pushed and moved by the packaging box bodies that are carried out one after another.
