In addition, in this specification and drawing, about the component which has the substantially same function structure, duplication description is abbreviate | omitted by attaching | subjecting the same code | symbol.

(Device configuration)
First, the configuration of the package take-out device according to the present embodiment will be described with reference to FIG. FIG. 1 is a schematic perspective view of a package take-out device according to the present embodiment. In FIG. 1, the portion hidden by the cardboard box is shown through.

  As shown in FIG. 1, the package take-out device 1 is used to open two conveyors 12 and 12 for mounting and transporting a cardboard box 2 and two outer bottom flaps 22 and 22 of the cardboard box 2. Two flap folding parts 14 and 14 and a lifting lifter 16 for pushing up a package (not shown) accommodated in the cardboard box 2 upward. The cardboard box 2 shown here is in a state where the upper surface is opened and the bottom surface is closed, that is, the upper surface inner flap and the upper surface outer flap are opened, and the bottom surface outer flap 22 is closed on the unillustrated bottom surface flap. Is in a state.

  In the present embodiment, the outer bottom surface flap 22 of the cardboard box 2 has a ruled line 24 along its longitudinal direction on the side connected to the side wall of the corrugated cardboard box 2, that is, the side serving as a fulcrum when the bottom surface outer flap 22 is opened. Is provided. Hereinafter, the side serving as the fulcrum with the ruled line 24 as a boundary is referred to as one end side piece, and the opposite side is referred to as the other end side piece. In the package take-out device 1 according to the present embodiment, the other end side piece of the bottom outer flap 22 is folded downward (folded) by the flap folding portion 14. The ruled line 24 serves as a fulcrum when the other end side piece of the outer bottom flap 22 is folded back, and is provided to facilitate the folding. In the present embodiment, the ruled line 24 is a cut and is formed on the front surface or the back surface of the outer bottom flap 22. In particular, by forming on the back surface, the other end side piece of the outer bottom flap 22 can be easily folded back. Note that the ruled line 24 is not a cut, but may be any process that facilitates the folding of the other end side piece of the outer bottom flap 22 such as a broken line in which holes are connected in a line.

  The transport conveyor 12 extends in the transport direction X, cooperates to transport the cardboard box 2 supplied from a supply conveyor (not shown) to a predetermined position, and packs the package by a package removal method described later at the position. Is removed, the empty cardboard box 2 is discharged to a discharge conveyor (not shown). Here, the predetermined position is a position where the approximate center of the package or cardboard box 2 overlaps the lifter 16. The width of the conveyor 12 has such a length that only a part of one end side piece of the cardboard box 2 abuts.

  Further, the transport conveyors 12 are arranged at a predetermined distance from each other in an orthogonal direction Y that is orthogonal to the transport direction X. The separation distance may be set as appropriate depending on the type of the cardboard box 2, the width of the supply conveyor, the discharge conveyor, and the like. Note that, as described above, since the other end side piece of the bottom outer flap 22 is folded back at the ruled line 24 of the bottom outer flap 22, the separation distance of the transport conveyor 12 needs to be more than the distance between the ruled lines 24. .

  The flap folding portion 14 folds the other end side piece of the bottom outer flap 22 downward, and is positioned below the conveyor 12 so that one flap folding portion 14 is provided for one bottom outer flap 22. Two are provided so as to correspond. These two flap folding parts 14 and 14 are disposed so as to be symmetrical with each other with a vertically extending vertical plane passing through the center between the flap folding parts 14 and 14 as a boundary. Each of the flap folding portions 14 includes one link mechanism 142 and two engagement portions 144.

  The link mechanism 142 is for swinging the engaging portion 144 within a predetermined movement range along the orthogonal direction Y, and includes two main rotating shafts 142a, four first connecting plates 142b, A second connecting plate 142c, two fixed plates 142d, and four rotating shafts 142e are provided.

  The two main rotary shafts 142a extend in parallel to the longitudinal direction of the bottom outer flap 22 in other words, in other words, in the direction in which the sides of the bottom outer flap 22 serving as a fulcrum when the bottom outer flap 22 is opened. At least one of them is connected to a driving device (not shown) and is rotated by driving the driving device.

  The first connecting plate 142b has one end connected to both ends of one main rotating shaft 142a in a relatively non-rotatable manner, and the other end pivotally supporting the rotating shaft 142e. The plate 142c is supported so as to be relatively rotatable. Therefore, the first connecting plate 142b can perform a rotational motion according to the rotation of the main rotating shaft 142a, and the second connecting plate 142c is moved so as to draw an arc by the rotational motion, that is, the vertical direction and the orthogonal direction Y. Can be swung along.

  The second connecting plate 142c is oscillated by the first connecting plate 142b. The upper end of the second connecting plate 142c supports the rotating shaft 144a of the engaging portion 144 so that the engaging portion 144 can be relatively rotated. I support it. In the present embodiment, the second connecting plate is provided by providing two sets of one main rotating shaft 142a and two first connecting plates 142b connected to the main rotating shaft 142a at a predetermined distance in the vertical direction. 142c is supported so as not to tilt.

  The fixed plate 142d is fixed at a lower position (not shown) and pivotally supports the main rotary shaft 142a at both ends thereof.

  Since the engaging portion 144 is supported by the second connecting plate 142c via the rotating shaft 144a so as to be relatively rotatable, the engaging portion 144 swings integrally with the second connecting plate 142c and rotates around the rotating shaft 144a. Can move. The engaging portion 144 engages with the other end side piece of the bottom outer flap 22 when swung upward, and therefore is positioned below the transport conveyor 12 at the reference position before swinging. It is arranged so that. In the present embodiment, two engaging portions 144 are positioned at the four corners of the bottom surface of the cardboard box 2, and two are provided in one flap folding portion 14 so that two correspond to one bottom surface outer flap 22. . Depending on the size and material of the cardboard box 2, one set or three or more sets of the engaging portion 144 and the second connecting plate 142c may be provided.

  The engagement portion 144 is provided with a suction cup 144b that can be adsorbed to the other end side piece of the outer bottom flap 22 at one end (upper end in FIG. 1). When the suction cup 144b comes into contact with the other end side piece of the bottom outer flap 22, the suction cup 144b can be adsorbed by driving a suction device such as a vacuum device (not shown). 22 is engaged with the engaging portion 144. The suction cup 144b is preferably configured so as to be able to appear and retract in consideration of changes in specifications such as the size of the cardboard box 2 and the position of the ruled line 24.

  Further, the engaging portion 144 is provided with a weight 144c at the other end, and the weight 144c is heavier than the suction cup 144b. As described above, since the engaging portion 144 is rotatably supported by the rotating shaft 144a, the suction cup 144b can be directed upward by the weight of the weight 144c in the initial state. Thereby, since the engaging part 144 rotates according to the displacement of the angle of the other end side piece part of the bottom surface outer flap 22 folded back downward, the engagement state between the piece part and the engaging part 144 is maintained. It is possible to satisfactorily fold back the piece. Note that the other end portion may be simply extended without providing the weight 144c at the other end portion of the engaging portion 144.

  It is preferable that the two flap folding portions 14 having such a configuration can be moved along a direction away from each other, that is, the orthogonal direction Y, integrally with the conveyor 12. By making it movable, it becomes possible to deal with cardboard boxes of various sizes.

  The lifter 16 is disposed substantially below the center between the conveyors 12 and is raised and lowered so that it can pass between the conveyors 12 and can be inserted into and removed from the cardboard box 2 by a driving device (not shown). A support stand 162 is provided at the tip.

  The support stand 162 is a flat plate member that comes into contact with and supports the package, and is connected to a piston rod that extends downward to be able to move up and down. The size of the support stand 162 may be a size that can be inserted into the cardboard box 2, but the length in the transport direction X is such that the two bottom flaps of the cardboard box 2 are folded and face each other. It is preferable to set it to the length between the front-end | tips of flaps in the bottom face. Moreover, it is preferable that the length of the support stand 162 in the orthogonal direction Y is equal to or shorter than the length between the ruled lines 24. This is because the other end side piece of the outer bottom flap 22 is folded around the ruled line 24 as a fulcrum.

Next, operation | movement of the package picking_out | removing apparatus which concerns on this embodiment is demonstrated in detail using FIGS. FIG. 2 is a view for explaining a state in which the cardboard box is arranged above the engaging portion of the flap folding portion, and FIG. 3 is a view for explaining a state in which the engaging portion sucks the flaps outside the bottom surface. . FIG. 4 is a view for explaining a state in which the engaging portion has folded a part of the bottom outer flap, and FIG. 5 is a diagram for explaining a state in which the engaging portion has finished folding a part of the bottom outer flap. FIG. FIG. 6 is a diagram for explaining a state before the package is taken out by the lifting lifter, and FIG. 7 is a diagram for explaining a state where the package is taken out by the lifting lifter. In each figure, one end side piece of the bottom outer flap 22 is indicated by reference numeral 222a, and the other end side piece is indicated by reference numeral 222b. 6 and 7, the package is indicated by reference numeral 3. The bottom flap is not shown.

  2 to 5 show a state in which one of the two engaging portions 144 (the left side shown in FIG. 1) is viewed along the conveying direction X. For the sake of explanation, the cardboard box 2 And the conveyor 12 is shown in cross section. The operation of the apparatus to be described below will be described as the operation of the engaging portion 144 shown in FIGS. 2 to 5, but naturally the same operation is performed in the engaging portion 144 on the side that is arranged symmetrically with respect to the vertical plane. Needless to say.

  First, as shown in FIG. 2, when the cardboard box 2 is arranged at a predetermined position by the transport conveyor 12, the engagement portion 144 and the one end side piece 222 a of the bottom surface outer flap 22 sandwich the transport conveyor 12. The other end side piece 222b of the bottom surface outer side flap 22 is positioned in a direction facing the engaging portion 144 that faces each other and in a direction approaching each other with the opposing engaging portion 144 (not shown). Become.

  In this state, the main rotating shaft 142a of the link mechanism 142 of the flap folding portion 14 is rotated counterclockwise, and the second connecting plate 142c is rotated in accordance with the rotation, and is engaged as shown in FIG. The part 144 moves upward so as to draw an arc. At this time, since the engaging portion 144 is rotatably supported by the rotating shaft 144a and the weight 144c is provided at the other end portion, the suction cup 144b moves while facing upward, and the suction cup 144b is moved. The bottom end outer flap 22 can be brought into contact with the other end side piece 222b.

  After the contact, the air in the suction cup 144b is drawn by the suction device, and the suction cup 144b is adsorbed to the other end side piece 222b of the bottom surface outer flap 22. After the suction, in order to return the engaging portion 144 to the reference position shown in FIG. 2, the main rotating shaft 142 is rotated in the reverse direction (clockwise), and the second connecting plate 142c is rotated in accordance with the rotation. 4, the engaging portion 144 moves downward so as to draw an arc. As described above, since the engaging portion 144 is rotatably supported by the rotating shaft 144a, the engaging portion 144 can be rotated around the rotating shaft 144a. Accordingly, the engagement portion 144 maintains the state of being engaged with the other end side piece portion 222b of the bottom outer flap 22, in other words, an angle formed by the other end side piece portion 222b and the engagement portion 144 (here. It is possible to move downward while maintaining 90 °. Thus, the other end side piece 222b of the bottom outer flap 22 can be folded downward with the ruled line 24 as a fulcrum.

  Note that when the other end side piece 222b of the bottom outer flap 22 is folded back, the load of the weight 144c is applied to the fulcrum portion where the ruled line 24 is provided. Therefore, the weight of the weight 144c is preferably heavier than the suction cup 144b without damaging the fulcrum portion. Further, when the other end side piece 222b of the outer bottom flap 22 is folded back, there is a possibility that some misalignment occurs between the other end side piece 222b and the suction cup 144b. Therefore, it is preferable that the suction force by the suction device is a suction force that can maintain the suction while allowing the positional deviation.

  Next, as shown in FIG. 5, by returning the engaging portion 144 to the reference position, the other end side piece 222b of the bottom outer flap 22 can be folded back approximately 90 °, and the bottom center portion of the package Can be exposed. Here, the other end side piece 222b of the bottom outer flap 22 is folded back approximately 90 °, but is not limited to this. The other end side piece 222b may be folded by rotating the main rotating shaft 142a to such an extent that the support stand 162 of the lifter lifter 16 can define a space that can be inserted into the cardboard box 2.

  After the folding, as shown in FIG. 6, toward the space that communicates the inside and outside of the cardboard box 2, which is defined by folding the other end side pieces 222 b of the two bottom outer flaps 22, The support stand 162 of the lifter 16 is raised. Since the raised support stand 162 enters the cardboard box 2 and abuts against the package 3, the package can be taken out upward by continuously raising the support stand 162.

  After the package is taken out, the support stand 162 of the lifter 16 is moved down and withdrawn from the cardboard box 2, and the cardboard box 2 emptied to the discharge conveyor by the transport conveyor 12 is transported to complete the present method. It should be noted that by continuously placing the cardboard box 2 that is the object of taking out the package at a predetermined position and repeating the operations described above, it is possible to realize continuous removal of the package.

  In addition, as shown in FIG. 8, the support stand 162 is packed together with the cover plate 4 together with the cover plate 4 by arranging the floor plate 4 having a certain degree of rigidity such as a wood plate, a metal plate, and a hard plastic sheet in the cardboard box 2. Can be taken upward. Therefore, even if the package 3 has poor stability, such as a film bag filled with a liquid used for BIB (back-in-box), extremely stable removal can be realized.

  According to the present embodiment, the other end side pieces 222b of the two bottom outer flaps 22 of the corrugated cardboard box 2 can be folded back, whereby the center of the bottom surface of the package 3 can be exposed. The package 3 can be pushed upward by 16 and taken out. Therefore, it is possible to easily take out various forms of the package 3 without applying an extra pressing force to the package 3. Moreover, since the flap folding | turning part 14 which folds the other end side piece part 222b of the bottom surface outer flap 22 can be implement | achieved by the simple mechanism by the link mechanism 142 and the engaging part 144, it can take out a package at compact and low cost.
