JP-A-6-263106 JP-A-9-301310 International Publication No. 94/02394

  All of the boxing devices disclosed in Patent Documents 1 to 3 contain articles adsorbed by a suction head in a cardboard box. However, when using the suction head described above, the flatness of the suction portion is required. For this reason, in order to transfer an article made of a bag-like packaging material whose outer shape can be deformed, the article has to be transferred in a lying state, and as a result, the lying article is often boxed. . As described above, there is a restriction that when a lying article is boxed, a box suitable for the size of the lying article must be prepared. In addition, when an article in a lying state is boxed, the articles are stacked and boxed, and there is a disadvantage that a burden is applied to the article underneath.

  Accordingly, an object of the present invention is to provide a boxing device that enables boxing of a group of articles in a standing posture.

  A packaging device according to one aspect includes a conveying unit that conveys an article group placed in a state where an article made of a packaging material partially overlaps an adjacent article to a predetermined position, and the article group in a standing position at the predetermined position. And a transfer means for transferring the article group in the standing posture from a predetermined position to a box in which the article group is accommodated.

In this case, since the article group in the standing posture can be transferred to the box by the transfer means after the article group has been put in the standing posture by the rising means, it is possible to pack the article group in the standing posture.
In addition, when the article group is transferred to various places in the standing posture, the standing posture of the article group is disturbed along with the conveyance, but in the present invention, the article group is in the standing posture at a predetermined position immediately before being accommodated in the box. Accordingly, the group of articles in the standing posture can be stably transferred.
In addition, since the group of articles can be brought into a standing state collectively, the packaging operation can be speeded up as compared with the case where the articles are individually raised.

  In the boxing device, the rising means includes a drive belt that comes into contact with the leading article of the article group.

In this case, the articles are sequentially raised from the top due to the friction between the packaging material and the drive belt, so that the group of articles can be surely placed in the standing posture.
Further, by placing the article at the head of the article group in which a part of adjacent articles overlap with each other with the driving belt, the entire article group can be easily put into the standing attitude.

  In the boxing device, the drive source of the conveying means and the drive source of the drive belt are common.

In this case, the article group can be brought into a standing posture by the drive belt simultaneously with the article group being conveyed to a predetermined position by the conveying means. As a result, the boxing operation can be speeded up.
Further, since the drive source for the conveying means and the drive belt is common, the packaging device can be reduced in size and cost.

  In the boxing device, the surface of the drive belt has an uneven shape.

  In this case, the article can be prevented from slipping on the surface of the drive belt, and the article can be reliably placed in the standing posture.

  In the boxing apparatus, the rising means is fixed in an inclined state with respect to the conveying surface of the article group.

  In this case, the article group is placed in an upright posture by moving the article group conveyed by the conveying means along the inclined rising means.

  In the boxing device, the inclination angle of the rising means with respect to the conveying surface can be adjusted.

  In this case, the angle of the standing posture of the article group can be adjusted. As a result, not only the group of articles standing upright in the direction perpendicular to the conveyance surface, but also the group of articles standing up in a predetermined angle direction with respect to the conveyance surface can be accommodated in the box.

  In the boxing device, the rising means is movable along the conveying direction of the article group.

  In this case, even if the size of the article group changes (change in the number of articles constituting the article group, change in the size of the articles that constitute the article group) or the size of the box changes, By adjusting the position of the means, boxing can be performed in response to these changes. As a result, a highly versatile boxing device can be obtained.

  In the boxing device, the conveying means includes a pair of bottom conveyors arranged side by side, and the rising means is provided in each of the pair of bottom conveyors.

  In this case, the group of articles conveyed by the bottom conveyor can be surely set in the standing posture by the pair of rising means. Thereby, it can prevent that disorder arises in the standing posture of an article group.

  In the boxing device, each of the pair of bottom conveyors is configured to be rotatable so as to form an opening for passing the transfer means therebetween, and the transfer means is configured to pass through the openings of the pair of bottom conveyors. The group of articles is transferred to a box arranged directly below.

  In this case, since the boxing operation of the group of articles can be performed directly below the bottom conveyor, the work space of the boxing device can be saved.

  The packaging device further includes an article detection sensor disposed upstream of the predetermined position from the predetermined position in the conveyance direction of the article group, and a suction unit that is provided in the transfer unit and sucks a part of the article group. When the article is not detected for a predetermined time, the suction unit stops or operates at a low speed.

  When there is no article to be processed in the adsorption unit, the operation of the adsorption unit is stopped or is operated at a low speed, so that power consumption in the adsorption unit can be suppressed.

  In the boxing device according to the present invention, it is possible to pack a group of articles in a standing posture.

(Operation of packaging equipment)
Next, with reference to FIG. 5 and FIG. 8 to FIG. 14, an operation in which the boxing device 100 packs the article group C into the cardboard box A will be described.

  As shown in FIG. 8, when the article group C in which a part of adjacent articles B overlaps is moved to the bottom conveyor 310R by the conveyance mechanism 200, the article group C is moved in the conveyance direction X on the conveyance belt 316R of the bottom conveyor 310R. Moved along. Then, the article group C moved along the conveying direction X is conveyed until the leading article B comes into contact with the drive belt 324R as shown in FIG. In the present embodiment, since the transport belt 316R and the drive belt 324R are interlocked with each other, as shown in FIG. 10, the article group C is transported in the transport direction X, and the leading article B is the drive belt 324R. The tip is lifted with driving. Thereafter, as shown in FIG. 11, the adjacent article B rises as the leading article B rises, and a plurality of articles B constituting the article group C rises sequentially from the beginning.

  As shown in FIG. 12, when all of the articles B constituting the article group C are in the standing posture, the driving of the transport belt 316R and the drive belt 324R is stopped. Next, the arm 411 rotates inward (in the direction of arrow F) and the arm 413 rotates inward (in the direction of arrow -F), so that the article group C in the standing posture is gripped as shown in FIG. . Thereby, the article group C is aligned and compressed, and the bulk of the article group C is suppressed. At this time, the article group C is sucked from the suction port 416A of the blower 416 so that the article group C does not fall during transfer. In particular, in the present embodiment, the blower 416 sucks the article B that the arm 411 and the arm 413 do not contact directly, thereby preventing the article B from falling during the transfer.

  In this embodiment, as shown in FIG. 5, the bottom conveyors 310R and 310L are rotated in opposite directions (arrow R direction, arrow -R direction) to form the opening T. As a result, as shown in FIG. 14, the article group C gripped by the catcher 410 is transferred to the cardboard box A disposed immediately below the bottom conveyors 310R and 310L via the opening T. Specifically, the catcher 410 holding the article group C is lowered in the direction of the arrow Z by the lifting mechanism 420, so that the article group C is conveyed to the cardboard box A. Next, the arm 411 and the arm 413 are each rotated outward, and the gripping of the article group C is released. In this way, the article group C in the standing posture is accommodated in the cardboard box A.

  The operation of the blower 416 is performed immediately before the article group C is gripped by the arm 411 and the arm 413 or immediately after the article group C is gripped. This is the period until is released. At this time, the controller 600 can control the required suction force based on the suction pressure acquired by the vacuum sensor 418. That is, in the present embodiment, a necessary suction force can be selected according to the shape and material of the packaging material of the article B, the weight of the article B, the number of the articles B constituting the article group C, and the like.

(Upper angle adjustment)
Next, a method for adjusting the angle of the rising portion 320R will be described with reference to FIG. In the present embodiment, the standing posture of the article group C can be adjusted by adjusting the angle of the upright portion 320R with respect to the conveyance surface of the article group C.

  The angle adjustment of the upright portion 320R is performed by adjusting the angle of the support plate 326R fixed to the angle adjustment plate 327R. Here, an example (see FIG. 15B) in which the upright portion 320R (see FIG. 15A) disposed substantially perpendicular to the transport surface is tilted in the transport direction X side will be described.

  First, as shown in FIG. 15A, the bolt 372R fastened to the hole 328R formed at the uppermost position of the angle adjustment plate 327R is removed, and the fixing of the support plate 326R and the angle adjustment plate 327R is released. Then, the angle of the support plate 326R is adjusted by tilting the support plate 326R around the bolt 373R in the transport direction X side. Here, as shown in FIG. 15B, the bolt 372R is tightened in the hole 328R of the angle adjustment plate 327R corresponding to the angle-adjusted support plate 326R. As described above, the angle of the rising portion 320R is adjusted.

(Position adjustment of the top)
Next, a method for adjusting the position of the upright portion 320R along the conveyance direction X will be described with reference to FIG. In the present embodiment, the article group C at an arbitrary position P, such as when the number of articles B constituting the article group C or the size of the article B changes by adjusting the position of the fixed position of the upright portion 320R. Can be in a standing posture.

  The position adjustment of the fixed position of the upright portion 320R is performed by moving the angle adjustment plate 327R in the transport direction X and the opposite direction. Specifically, the fixed position of the upright portion 320R is adjusted by moving the angle adjusting plate 327R along the long hole 319R formed in the side plate 318R. Here, as shown in FIGS. 16A and 16B, an example in which the upright portion 320 </ b> R disposed on the transport mechanism 200 side is moved in the transport direction X will be described.

  As shown in FIG. 16A, in the upright portion 320R arranged on the transport mechanism 200 side, first, the bolt 373R that fixes the angle adjusting plate 327R to the side plate 318R is loosened. Thereby, the fixation between the angle adjustment plate 327R and the side plate 318R is released, and the angle adjustment plate 327R can move along the long hole 319R. Here, the angle adjustment plate 327 </ b> R is moved along the transport direction X and is arranged at an arbitrary position. Therefore, by tightening the bolt 373R, the angle adjusting plate 327R is fixed to the side plate 318R, and the position of the upright portion 320R is adjusted.
