As shown in FIG. 8, the control unit 100 of the boxing device 10 includes a driving motor 45 for the first conveyor 41 and a driving motor 46 for the second conveyor 42 (both receiving members) in the box vertical movement unit 10B. 43 and 44 and the height of the box Y received by the receiving members 43 and 44), and the width adjusting actuators (for example, motors) 47 of these conveyors 41 and 42 are driven and controlled.

  As illustrated in FIG. 6, the box discharge moving unit 10 </ b> C is an L-shaped box discharge sheet 51, and travels to reciprocate the sheet 51 back and forth between the front side and the back side of the boxing device 10. Belt 52. The discharge sheet 51 can rotate about 90 ° around the support shaft 53. The discharge sheet 51 stands by just below the first conveyor 41 of the box up-and-down moving unit 10B, as indicated by reference numeral (a). At this time, the discharge sheet 51 is located between the left and right traveling surfaces of the second conveyor 42.

  As described above, when the box Y is delivered from the second conveyor 42, the discharge sheet 51 starts to move backward in the direction of the back of the boxing device as indicated by an arrow. During the retreating period, as indicated by reference numeral (b), the discharge sheet 51 is slightly inclined in the rear direction, and the opening O of the box Y faces slightly upward. Then, when the discharge sheet 51 reaches the rear end portion of the traveling belt 52, the discharge sheet 51 stops retreating and rotates completely 90 ° in the rear direction as indicated by reference numeral (c). Thereby, the box Y stands up from the sideways state, and the opening O faces right above. Thereafter, the box Y is taken out from the boxing device 10. As shown in FIG. 8, the control unit 100 of the boxing device 10 drives and controls the rotation motor 54 and the movement motor 55 of the box discharge sheet 51 in the box discharge movement unit 10C.

  As shown in FIGS. 7 and 9, the article pushing portion 10 </ b> D includes a bottom plate 61 extending from the transport device 20 to the box vertical movement portion 10 </ b> B, and left and right side guides 62 erected on the top surface of the bottom plate 61. . The bottom plate 61 provides a lower support surface that supports the bag X discharged from the transport device 20 from below until it reaches the box vertical movement unit 10B. The side guides 62 are wide on the conveying device 20 side and narrow on the up-and-down moving unit 10B side, and each set of 12 standing bags discharged from the conveying device 20 onto the bottom plate 61. Before X ... X is packed in the box Y of the up-and-down moving part 10B, the width is adjusted in the column direction to the width of the opening O (specifically, the width in the horizontal direction) of the box Y.

  The article pushing section 10D includes two pushers 63 and 64 as pushing means for pushing the group of bags X... X aligned horizontally in the standing posture into the box Y of the vertical movement section 10B. One is a preliminary pusher 63, which is provided below the bottom plate 61 on the conveying device 20 side. The auxiliary pusher 63 has a structure in which the push rod 66 is moved by a pendulum at an angle of about 70 ° around the support shaft 65 so as to protrude from the bottom of the bottom plate 61 to the upper surface. The push rod 66 extends horizontally to the left and right beyond the width of the side guide 62 and presses the rear end of the bag X in the moving direction C of the bag X (for example, corresponding to the upper end portion of the bag X). Is slightly away from the transfer device 20 and slightly closer to the up and down moving unit 10B. As clearly shown in FIG. 9, the side guide 62 is formed with an arc-shaped groove 67 so as not to interfere with the protruding and protruding of the push rod 66.

  Another pushing means is the main pusher 64, which is provided above the bottom plate 61. The pusher 64 moves the pushing flap 68 horizontally from the conveying device 20 side to the vertical movement unit 10B side, thereby moving the rear end of the bag X slightly moved to the vertical movement unit 10B side by the preliminary pusher 63. And the bag X is pushed into the box Y through the opening O. The push-in flap 68 is rotatable about 90 ° around the support shaft 69, protrudes downward only when the bag X is pressed, and pulls upward so as not to interfere with the rest.

  The article pushing portion 10D further includes a lower support mechanism 70 as a means for providing a lower support surface for supporting the bag X from below from the bottom plate 61 into the box Y. The lower support mechanism 70 causes a lower support plate 71 extending horizontally in parallel to the bottom plate 61 to protrude from the bottom of the bottom plate 61 toward the up and down moving unit 10B, thereby causing the lower support plate 71 to pass through the opening O. In this configuration, the box Y is advanced and retracted.

  As shown in FIG. 8, the control unit 100 of the boxing device 10 pushes the turning drive actuator 72 (for example, a rotating cylinder) 72 of the push rod 66 of the spare pusher 63 and the main pusher 64 in the article pushing portion 10D. The actuator for driving the rotation of the flap 68 (for example, a rotating cylinder) 73, the actuator for driving the pressing of the pressing flap 68 (for example, a direct acting cylinder) 74, and the actuator for advancing and retracting the lower support plate 71 of the lower support mechanism 70 (for example, a (Dynamic cylinder) 75 is driven and controlled.

  In addition, the control unit 100 of the boxing device 10 may be arranged so that the lid of the box Y (four flaps F around the opening O: see FIG. Is moved up and down, left and right, while driving and controlling the box lid opening mechanism 80, exchanging signals with the control unit 200 of the transport device 20, and the upstream weighing device and the like. Smooth and good overall operation of this boxing device 10 by exchanging signals with various peripheral devices and sensors such as bag making and packaging equipment, box making machines or stockyard management equipment for downstream box Y. A large number of bags (a total of 24 bags) X... X are packed in a box Y in a reliable, clean and high speed manner.

  Hereinafter, an example of a specific operation of the boxing device 10 will be described with reference to FIGS. First, as shown in FIG. 9, when a group of bags X... X aligned horizontally in a standing posture is conveyed by the conveying device 20 to the front of the boxing device 10, the comb-shaped plate 25 is moved in the direction of the arrow c. As shown in FIG. 10, the group of bags X... X are pushed out onto the bottom plate 61. Next, the push rod 66 of the preliminary pusher 63 presses the group of bags X... X to move the bags X... X toward the box Y a little as shown in FIG. At this time, as clearly shown in FIG. 7 (b), the bags X... X are neatly arranged in the column direction by the left and right side guides 62 so as to be approximately the same width as the opening O of the box Y.

  Next, as shown in FIG. 12, the pushing flap 68 of the pusher 64 protrudes downward, and further, as shown in FIG. 13, the pushing flap 68 moves forward, and the group of bags X. It pushes into the box Y of the up-and-down moving part 10B through the opening O with the one-row system (packing of the first-stage bag X). As shown in FIGS. 9 to 10, the box Y has been transferred from the box horizontal moving unit 10 </ b> A to the box vertical moving unit 10 </ b> B as shown in FIG. 9 to FIG. It descends to the height indicated by the symbol α. If the lower support plate 71 is inserted into the box Y, the height α is such a height that the support plate 71 just contacts the lower inner surface of the box Y. Then, as shown in FIGS. 11 to 13, the lower support plate 71 is horizontally inserted into the box Y. As shown in FIG. 13, the bags X... X pushed into the box Y are placed on the lower support plate 71.

  Next, as shown in FIG. 14, the lower support plate 71 is retracted, and the box Y is further lowered by the first conveyor 41 to the height indicated by the symbol β in FIG. Assuming that the lower support plate 71 is inserted into the box Y, the height β is such that the support plate 71 is located above the first stage bag X in the box Y, The height is such that it does not touch. Then, as shown in FIG. 15, the lower support plate 71 is inserted into the box Y again. Next, as shown in FIG. 16, the box Y is slightly raised by the first conveyor 41 to the height indicated by the symbol γ in FIG. 5B. This height γ is a height at which the lower support plate 71 inserted into the box Y presses the first-stage bag X in the box Y slightly downward from above. Therefore, as clearly indicated by the symbol H in FIG. 16 and FIG. 5B, a space for pushing the next second-stage bag X is widened in the box Y, and such multi-stage packing operation is smooth and good. Proceed to

  Then, returning to FIG. 9, the push-in flap 68 of the pusher 64 moves forward, and the next group of bags X... X is kept in a single row system in the box Y at the height of γ. It pushes in through the opening O (packing of the second-stage bag X). Also at this time, as shown in FIG. 9, the second-stage bag X ... X pushed into the box Y is placed on the lower support plate 71 inserted into the box Y, and the box is packed first. There is no such thing as entering the first-stage bag X ... X.

  As shown in FIG. 13, the next second-stage bag X... X is transferred to the box Y by the transport device 20 when the previous first-stage bag X. It is transported to the front (substantially equivalent to FIG. 9). Then, as shown in FIGS. 14 to 16 and FIG. 9, the auxiliary pusher 63 and the main pusher 64 are used to pack the box as described above (substantially corresponding to FIGS. 10 to 13).

  Boxes Y in which a total of 24 bags X... X are packed in one layer and two tiers are delivered from the first conveyor 41 to the second conveyor 42 as shown in FIGS. Further, after being placed on the sheet 51 of the box discharge moving unit 10C from the second conveyor 42, as described above, it is moved backward in the back direction of the boxing device 10 so that the opening O faces upward. It is stood up, taken out from the boxing device 10, and carried into, for example, a stock yard of a box Y provided on the downstream side.

  As described above, the boxing device 10 is a boxing device of a type in which a group of articles X... X aligned in a horizontal direction in a standing posture are put into a box Y from the side. And since the said box Y and the pushing position (boxing position) of the articles | goods X in this box Y are relatively displaced to an up-down direction, the relative displacement is set to the distance etc. which are equivalent to the height of the articles | goods X, for example By doing so, the packaging position of the article X can be changed by approximately one row (one step) in the vertical direction of the opening O of the box Y. Therefore, a group of aligned articles X... X can be boxed one by one in the vertical direction of the opening O of the box Y (one step at a time), and the articles X can be packed in the box Y in multiple stages. It becomes.

  In that case, the articles X to be boxed at one time are not stacked in a multi-stage from the beginning, but are only the one-stage articles X aligned in one row, so that the one-stage at a high speed without worrying about collapse. Only the article X can be moved toward the box Y. That is, the push-in speed of the pusher 64 can be increased. Then, by stacking the articles X in the box Y one by one (one step at a time), the articles X can be reliably and neatly packed in multiple stages.

  Further, by moving the box X downward between the article X and the box Y, the box Y and the packaging position of the article X are relatively displaced. The mechanism (for example, the transport device 20), the width adjusting mechanism (for example, the side guide 62), or the pushing means 63, 64 for pushing the article X into the box Y need not be structured to be movable in the vertical direction. The complication of the structure of 10 is suppressed.

  Further, the lower support plate 71 inserted into the box Y can partition the second-stage article X to be boxed next and the first-stage article X previously boxed, so that the two-stage During the packaging of the eyes, it is possible to prevent the row of the articles X from being disturbed and the articles X from entering and mixing with the adjacent first row, thereby achieving a more reliable and clean multi-stage packing. Is done.

  In addition, after the box Y is moved downward from the height α to the height β between the first-stage boxing and the second-stage boxing, and the lower support plate 71 is inserted into the box Y, Since the box Y is once again moved slightly upward to the height γ, before the next second-stage article X is boxed, the first-stage article X previously boxed is slightly moved by the lower support plate 71. The space for pushing the second-stage article X is widened in the box Y, and the multi-stage boxing operation proceeds smoothly and satisfactorily. Moreover, when the boxing operation is completed, the lower support plate 71 is pulled out from the box Y (see FIGS. 9 to 10). At that time, the boxed articles X... FIG. 5 (b) and FIG. 6), a clean and orderly multi-stage packing without gaps is achieved.

  Further, since the group of articles X... X before boxing is provided with side guides 62 that bring the width of the opening Y of the box Y to the width of the opening O in the row direction, the group of articles X. During the movement toward the box Y, the width is surely reduced to the width of the opening O of the box Y, and the rows are pushed into the box Y in an orderly manner without being disturbed.

  By the way, as illustrated in FIGS. 9 to 10 and FIGS. 14 to 16, in the boxing device 10, the movement path in the vertical direction of the box Y (specifically, in the box vertical movement unit 10 </ b> B, the article pushing unit) A cover member 90 that closes the opening O of the box Y is disposed in a portion below 10D. Thereby, it is possible to prevent the article X packed in a box from popping out of the box Y due to pressure or the like. In particular, as a result, the shortage of the number of articles X in the box Y can be prevented. That is, since the opening O of the box Y is covered with the cover member 90 during the period in which the box Y is moved in the vertical direction, even if the already packed box X is pushed out during the vertical movement period, The article X is prevented from jumping out of the box Y through the opening O, and the number of articles X in the box Y is guaranteed.

  In this regard, as shown in FIG. 6, before the box Y that has been packed is raised so that the opening O faces upward, the box Y is tilted so that the opening O faces slightly upward. From (state b), even when the box Y is erected from the sideways state to the upright state, the opening O of the box Y once faces slightly upward, and the already packed article X is pushed out even during this standing work period. The article X is prevented from jumping out of the box Y through the opening O.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIG. The second embodiment shows another example of measures for preventing the article X from jumping out from the box Y, instead of the cover member 90. First, as shown in FIG. 17 (a), the vertical movement path of the box Y (the box vertical movement part 10B) is inclined so that the opening O of the box Y faces slightly upward. is there. In this way, since the opening O of the box Y faces slightly upward during the period in which the box Y is moved in the vertical direction, even if the already packed article X is pushed out during the vertical movement period, The article X is suppressed from jumping out from the opening O.

  Secondly, as shown in FIG. 17B, the opening of the box Y slightly moves up and down slightly without tilting the moving path of the box Y (the box up / down moving unit 10B) itself. It is to maintain a posture that faces upward. Similarly, even when the article X is pushed out during the period in which the box Y is moved in the vertical direction, the article X is prevented from jumping out of the box Y.

  In addition, since the packaging device 10 packs the standing bag X, it is preferably combined with the conveying device 20 of the type that collects, aligns, conveys, and discharges the standing bag X as in the above embodiment. Can be used.

  Further, in order to relatively displace the box Y and the packaging position of the article X (including the change from the height β to γ), the article X is replaced with or along with the movement of the box Y. Of course, you can move up and down. Further, the present invention is also suitable for use in a multi-stage packing and multi-layer packing boxing apparatus.

[Third Embodiment]
Next, a third embodiment of the present invention will be described with reference to FIGS. This embodiment is different from the above-described embodiment in that an apparatus for taking out a box-making sheet Z one by one from a plurality of box-making sheets Z folded and accumulated, and forming the box-making sheet Z in a box-making box Y. The point that is embedded is greatly different.

  First, as shown in FIG. 18, the present apparatus is a sheet magazine 300 (in which a plurality of folded box making sheets Z provided at the rear in the insertion direction of the article X into the box Y are stacked and stocked in a horizontal state. Sheet take-out section 400, which is provided above the sheet magazine 300 and takes out the box-forming sheets Z stacked on the top from the sheet magazine 300 one by one, and a sheet take-out section A horizontal conveyance unit 500 that conveys the box-making sheet Z taken out from 400 in the horizontal direction in the horizontal direction upstream of the apparatus in the α direction, which is the direction opposite to the insertion direction of the article X, and the horizontal conveyance unit 500 A box-making unit 600 that opens the box-making sheet Z that has been conveyed and forms a box shape with the opening sideways, and a lower-conveying unit 700 that conveys a box-shaped box Y formed by the box-making unit 600 downward. When A tape applying part 800 for attaching the bottom flap part of the box Y conveyed by the lower conveying part 700 with a folding tape, and an insertion part arranged below the tape applying part 800 for inserting a plurality of articles X into the box Y. 900, a box inverted portion 1000 in which the box Y in which the article X is inserted by the insertion section 900 is turned 90 degrees and the opening portion is upward, and a box Y in which the opening portion is upward in the box inverted portion 1000 is the article X. And a box discharge section 1100 that conveys downstream in the β direction, which is the insertion direction.

  The sheet magazine 300 has a sheet supply position 310 on which a plurality of box-making sheets Z are placed, and a sheet set position 320 disposed adjacent to the α direction (see FIG. 19) of the sheet supply position 310. Yes. Further, a conveyance belt (not shown) that supports and conveys the bottoms of the plurality of box-making sheets Z from the sheet supply position 310 to the sheet setting position 320 is provided at the bottom. Further, each time a sheet-making sheet Z is taken out by the sheet take-out unit 400, an elevating unit 330 that lifts the plurality of box-making sheets Z upward is disposed at the sheet setting position 320. The lifting / lowering unit 330 is lifted by a lifting / lowering motor (not shown) at a thickness pitch of one box-making sheet Z, and a box-making sheet Z detection unit (not shown) is used to move all the box-making sheets Z at the sheet setting position 320. When it disappears, the sheet lowers to the same height as the sheet supply position 310. In addition, the raising / lowering part 330 is arrange | positioned so that it may not interfere with a conveyance belt at the time of raising / lowering.

  The sheet take-out unit 400 includes four suction portions 410 having suction cups that suck and hold the box-making sheet Z at the sheet setting position 320 from above, and are arranged at the four corners of the box-making sheet Z. The suction part 410 can adsorb and desorb the box making sheet Z by a vacuum device and an opening / closing valve (not shown).

  The horizontal conveyance unit 500 supports a side opening / closing frame 510 that supports a lower side of the box-making sheet Z that has been moved upward by the suction unit 410, and is fixed in the α direction adjacent to the side opening / closing frame 510 at the same height. A side support frame 520 that supports the lower side of the box-making sheet Z, and a pair of upper belts 530 provided above the side opening / closing frame 510 and the side support frame 520. .

  The side opening / closing frame 510 performs a horizontal opening / closing slide operation on a horizontal plane orthogonal to the α direction. The upper belt 530 sandwiches the side of the box-making sheet Z from above and below with the side opening / closing frame 510 and the side support frame 520, and drives the belt in the α direction, so that the box-making sheet Z is kept in a horizontal state. To 600.

  The box making unit 600 has a box making opening / closing frame 610, an upper suction part 620 for sucking and supporting the upper side of the box making sheet Z, and a drive unit (not shown) that sucks from the lower side of the box making sheet Z. By rotating vertically, the box making sheet Z is opened, and the box is formed into a side suction part 630 that forms a box Y, and the box Y from the side opening in the β direction of the box Y (see FIG. 19). A horizontal sheet opening member 640 that is inserted inside Y and horizontally supports the inside upper side of the box Y to maintain the box-like shape of the box Y, and an inner lower side of the box Y by being orthogonal to the horizontal sheet opening member 640 And a vertical sheet opening member 650 that holds the sheet. The horizontal sheet opening member 640 and the vertical sheet opening member 650 correspond to the sheet opening member. The upper adsorbing part 620 adsorbs four adsorbing parts that adsorb the part that becomes the side wall of the box Y, two adsorbing parts that adsorb the part that becomes the lid wall of the box Y, and 2 that adsorbs the part that becomes the bottom wall of the box Y. It consists of two adsorption parts. The side suction part 630 is composed of four suction parts that suck the part that becomes the side wall of the box Y, and unlike the upper suction part 620, there is no suction part that sucks the part that becomes the lid wall or the bottom wall of the box Y. . Further, the upper suction portion 620 and the side suction portion 630 can adsorb and desorb the box-making sheet Z by a vacuum device and an opening / closing valve (not shown).

  The lower conveyance unit 700 includes eight side angle holding units 710, a horizontal sheet opening member 640, and a vertical sheet opening member 650, and opening member moving means (not shown) that moves downward. The eight side corner holding portions 710 hold the side corners of the box Y from the outside with the claws while adsorbing the upper and lower sides of the box Y and the side corners on the lid side and the bottom side of the box Y. The box Y is a cube of the box Y formed by the box making unit 600 by moving the sheet opening members 640 and 650 inserted therein and the side-side holding part 710 holding the box Y from the outside of the box Y downward. It is moved downward while maintaining the shape.

  The tape sticking unit 800 is arranged in a direction opposite to the insertion side of the article X with respect to the box Y in the middle of being conveyed by the lower conveying unit 700. The tape applying unit 800 folds the bottom flap of the box Y with a bottom folding member (not shown), and affixes the tape to the flap formed with the bottom folding member to fix the bottom shape.

  The insertion part 900 inserts a plurality of articles X from the opening part on the side of the box Y formed in a box state. The operation is the same as in the first embodiment. The box inverted portion (or box inverted portion) 1000 is rotated 90 degrees so that the bottom of the box Y into which the plurality of articles X are inserted is downward. The operation is the same as in the first embodiment. The box discharge unit 1100 discharges the box Y in the β direction with the opening of the box Y into which the plurality of articles X are inserted facing up. The operation is the same as in the first embodiment. Each of the drive units, the suction units, and the like are connected to a box control unit 100 shown in FIG.

  Next, the operation will be described with reference to FIG. First, a plurality of box-making sheets Z folded manually by the sheet supply position 310 are stacked and supplied in a horizontal state. Next, the sheet is conveyed to the sheet setting position 320 by the aforementioned conveyance belt. Next, the box making sheets Z stacked at the sheet setting position 320 are collectively raised to the sheet take-out unit 400 by the elevating unit 330. In the sheet take-out unit 400, the upper surface of the uppermost box making sheet Z is adsorbed by the adsorbing unit 410 and raised to the height of the horizontal conveying unit 500.

  Next, the box-making sheet Z conveyed to the horizontal conveyance unit 500 is in the open state, so that the side opening / closing frame 510 is closed (the pair of side opening / closing frames 510 approach horizontally). The lower part is supported by the frame 510.

  Next, the suction of the suction part 410 is stopped. In this state, the box making sheet Z is sandwiched between the side opening / closing frame 510 and the upper belt 530. Next, by driving the upper belt 530 in the α direction, the box making sheet Z is conveyed in the α direction. At this time, the box making sheet Z is conveyed to the box making unit 600 while being sandwiched between the side support frame 520 and the upper belt 530 that are extended to the side opening / closing frame 510. When the box making sheet Z is conveyed to the box making unit 600, the box making sheet Z is sucked and held from above by the upper suction unit 620. At this time, the upper belt 530 stops.

  Next, the side suction part 630 sucks the lower side of the box-making sheet Z (the part that will later become the side wall of the box Y) and rotates 90 degrees in the vertical direction to open the box-making sheet Z. Next, the horizontal sheet opening member 640 and the vertical sheet opening member 650 having an angle slightly inclined with respect to the vertical direction are simultaneously inserted from the inside into the opened portion from the β direction. Thereafter, the vertical sheet opening member 650 rotates and becomes vertical so that the horizontal sheet opening member 640 and the cross section T are formed, whereby the box Y is held in a box shape from the inside. Next, the suction of the upper suction part 620 and the side suction part 630 is stopped.

  Next, the horizontal sheet opening member 640 and the vertical sheet opening member 650 are moved to the lower tape applying portion 800. Here, the bottom part of the box Y is attached with tape while the bottom flap is folded with the bottom folding member. Therefore, the bottom of the box Y is formed. At this time, the side angle holding part 710 comes closer to the side of the box Y and is adsorbed immediately before the tape is applied. Further, the side corners of the box Y are held from the outside by the claws. After the tape application is completed, the horizontal sheet opening member 640 and the vertical sheet opening member 650 are pulled out from the inside of the box Y, and the side corner holding part 710 moves downward to move the box Y to the insertion part 900. Let

  After that, the article X is inserted as in the first embodiment. At this time, when the articles X are stacked in two stages, the side angle holding portions 710 are moved downward at the height pitch of the articles. Thereafter, the box Y in which the insertion of the article X is completed is rotated 90 degrees by the box inverted portion 1000 and is discharged by the box discharge portion 1100 with the opening portion facing upward.

  In the sheet magazine 300, the sheet take-out unit 400, the horizontal conveyance unit 500, the box making unit 600, the lower conveyance unit 700, the tape applying unit 800, the insertion unit 900, and the box inverted unit 1000, each operation is completed until the operation is completed. The box Y and the box making sheet Z are not moved between the parts.

[Features of this device]
By arranging the sheet take-out unit 400, the horizontal conveyance unit 500, and the sheet magazine 300 directly above, an increase in installation space is prevented. In addition, the box-making unit 600 is disposed directly above the insertion unit 900 to prevent an increase in installation space. That is, since each part is arranged in three dimensions, an increase in installation space is effectively prevented. In other words, since the box making unit 600 is attached to the upper part of the apparatus, the installation space in the lateral direction (width direction) is not increased, and a limited space in a factory or the like is sufficiently effectively used.

  Moreover, since the folded box-making sheet is conveyed in a horizontal state, the installation space in the height direction of the boxing device can be reduced even if each part is arranged three-dimensionally. Further, since the box-making sheet Z is transported in a horizontal state, the sheet can be transported more stably than when transported in a vertical state.

  Further, since the opening of the box is set in the horizontal direction with respect to the apparatus and the article is inserted into the box from the horizontal direction, the installation space in the height direction is compared with the case where the article is inserted from above with the upper part of the box as the opening. Can be suppressed. Further, by inserting from the lateral direction, it is possible to insert the article into the box while keeping the alignment state of the articles satisfactorily. In particular, the effect is high when a plurality of non-self-supporting articles X with soft articles X are inserted.

  Since the sheet take-out unit takes out the box-forming sheets one by one from the sheet storage unit to the horizontal conveyance unit, the labor of placing the sheet on the horizontal conveyance unit can be saved.

  The box making unit can hold the box in an open state with a simple structure by inserting a plurality of sheet opening members into the opening of the box making sheet and making them perpendicular to each other. Further, since the box Y is held from the inside, no new holding means such as suction is required even when the box Y is transported downward. Furthermore, even if the suction of the side suction part 630 that attempts to open the box from the outside by the box making part 600 is removed in the middle of the opening, the box is prevented from dropping and dropping out of the apparatus. Not only the opening of the box is achieved by the action of the sheet opening member. Further, since the reused cardboard case or the like has an unstable flap state, it is difficult to hold the flap. As a result, when the box is delivered to the lower transfer unit 700, the side corner holding unit 710 of the lower transfer unit 700 may not hold the box Y reliably, and the box may be crushed. However, since the sheet opening member holds the opening state of the box from the inside in this respect, an unstable place for holding the box is eliminated, and the box is reliably transferred to the side corner holding unit 710 of the lower conveyance unit 700. Will be able to.

  By disposing the horizontal conveyance unit, the box making unit, the lower conveyance unit, and the insertion unit above the discharge unit, installation space can be further reduced.

  And the box discharge part (equivalent to the "discharge conveyance part" of a claim) 1100 which conveys the box Y where the opening part became the upper part in the box inverted part 1000 to the downstream of (beta) direction which is the insertion direction of the goods X Are arranged in parallel immediately below the horizontal conveyance unit 500. That is, the box Y in which the article X is packed and the opening portion faces upward is finally discharged to the box discharge portion 1100. In that case, since the box discharge section 1100 is arranged in parallel directly under the upper horizontal conveyance section 500, the transfer path from the first box-making sheet Z to the last box Y is U-shaped in a side view. In other words, it becomes a vertical circulation path, and as described above, in addition to the installation space in the horizontal direction (width direction) and the installation space in the height direction, the installation space in the length direction can also be suppressed. All three-dimensional sizes in the vertical, horizontal, and height directions of this device, as well as the occupied space, can be minimized, and more and more limited spaces such as factories are effectively used.

[Fourth Embodiment]
Next, a fourth embodiment of the present invention will be described with reference to FIGS. The fourth embodiment is different from the third embodiment in that the sheet opening members 640 and 650 of the box making unit 600 operate so as to be separated from each other when the box is opened. In the following description, the terms “up”, “down”, “left”, “right”, “front”, and “rear” refer to the directions shown in FIG.

  As shown in FIGS. 20 and 21, in this embodiment, the horizontal sheet opening member 640 is divided into two left and right blades 641 and 642. On the other hand, the vertical sheet opening member 650 is a single blade 651. The left and right blades 641 and 642 are movable in the left-right direction along a guide rail or the like (not shown), and a single blade is below the upper left upper position and the lower right lower position by a link or the like (not shown). (The turning center is fixed: the turning center is indicated by a black circle in the figure). In the box making unit 600, the driving means 643 and 644 (see FIG. 23) for independently moving the left and right blades 641 and 642 as described above, for example, the fluid cylinder and the lower blade 651 are rotated as described above. Drive means 652 (see FIG. 23), for example, a drive motor or a fluid cylinder is provided. Further, a preparation means 653 (see FIG. 23) for adjusting the turning radius of the lower blade 651, for example, a fluid cylinder is also provided.

  The three blades 641, 642, 651 are close to each other before being inserted into the box Y. That is, the left blade 641 moves to the right, the right blade 642 moves to the left, and the lower blade 651 moves to the upper left upper position. In the box making unit 600, when the box Y is slightly opened by the side suction unit 630, the assembled blades 641, 642, 651 rush toward the slightly opened opening. Then, the drive means 643, 644, 652 move away from each other. That is, the left blade 641 moves to the left, the right blade 642 moves to the right, and the lower blade 651 moves to the lower right lower position (directly below the right position of the right blade 642). As a result, the left blade 641 presses the upper left corner of the box Y outward from the inside, the right blade 642 presses the upper right corner of the box Y from the inside outward, and the lower blade 651 Press the lower right corner of the outside from the inside. At this time, the turning radius of the lower blade 651 is adjusted by the preparation means 653 so that the lower blade 651 reaches the lower right corner of the box Y. As a result, the box Y is held open by the three blades 641, 642, 651.

  In this case, the separating operation of the blades 641, 642, 651 is performed almost in synchronization with the opening operation of the side suction unit 630, and operates slightly delayed to assist the opening operation of the side suction unit 630. . In the box making unit 600, three blades 641, 642, 651 are integrally inserted into the opening of the box Y as described above, and a front / rear drive means 610 (see FIG. 23) for drawing out from the opening, for example, a fluid cylinder is provided. Is provided.

  On the other hand, as shown in FIG. 22, in this embodiment, flap folding members 645 and 646 are attached to the right blade 642 and the lower blade 651. That is, the flap folding members 645 and 646 of the blades 642 and 651 are provided at positions corresponding to the lid flap F when the blades 642 and 651 are inserted into the box Y. The flap folding member 645 of the right blade 642 protrudes to the right side, and the right lid flap F standing around the opening of the box Y is folded outward when moving right. On the other hand, the flap folding member 646 of the lower blade 651 projects downward, and the lower lid flap F standing around the opening of the box Y is folded outward when moving downward.

  Further, the box making unit 600 is provided with vertical drive means 620 (see FIG. 23) for moving the three blades 641, 642, 651 up and down integrally, for example, a drive motor or a fluid cylinder. Therefore, when the blades 641, 642, 651 are moved downward while being separated by the driving means 620, the box Y is transported downward while the open state is maintained. Then, the transported box Y is delivered to the side angle holding unit 710 provided in the lower transport unit 700.

  As shown in FIG. 23, in this embodiment, the control unit 2000 controls each of the means 610, 620, 643, 644, 652, 653 to first bring the assembled blades 641, 642, 651 into place. Entry into the box Y together, then move away from each other to hold the opening of the box Y, move downward integrally in that state, transfer to the side corner holding part 710 of the lower conveyance part 700, and then gather Next, a series of operations are repeated, such as drawing out from the box Y, moving it upward, and waiting at the opening of the next box Y.

In this case, in this embodiment, the box Y opened by the box making unit 600 is opened by the right reference, the upper reference, and the front reference. That is, when the size of the box Y is changed, the positions of the left side, lower side, and rear side members are changed so as to correspond thereto. Therefore, the control unit 2000 controls the left blade so as to variably control the left moving position of the left blade 641 and the lower position of the lower blade 651 based on the information regarding the size of the box Y input from the input unit 1200. The driving means 643 of 641 and the preparation means 653 of the lower blade 651 are controlled. That is, comparing FIG. 20 with FIG. 21, the right movement position of the reference right blade 642 does not change, but the left movement position of the other left blade 641 and the lower position of the lower blade 651 depend on the size of the box Y. Have changed.
[Features of this device]

  In this apparatus, since the sheet opening members 641, 642, 651 operate so as to be separated from each other, the corners of the box Y are spread from the inside, and the box Y is accurately and accurately positioned and held open. Is possible. In that case, since the sheet opening members 641, 642, 651 support the box Y from the inside, the suction of the side suction unit 630 that attempts to open the box Y from the outside by the box making unit 600 is in the middle of the opening. Even if the box Y is detached, not only is the box Y falling and falling out of the apparatus, but the opening of the box Y is achieved without any trouble by the operation of the sheet opening members 641, 642, 651. The same effect as in the third embodiment is also achieved.

  Further, when the sheet opening members 641, 642, 651 are separated, that is, when the box Y is opened, the lid flaps standing around the opening of the box Y are easily folded outward simultaneously by the sheet opening members 642, 651. Therefore, the working time of this apparatus can be shortened.

  Then, after the box Y is held open, the sheet opening members 641, 642, 651 that support the box Y from the inside convey it downward while holding the box Y in the open state. Even when the holding unit 710 grips the box Y from the outside, the interference between the side corner holding unit 710 and the sheet opening members 641, 642, 651 can be avoided, and the box Y is received well by the lower conveyance unit 700. It becomes possible to pass.

[Fifth Embodiment]
Next, a fifth embodiment of the present invention will be described with reference to FIG. In the fifth embodiment, in the box inverted portion 1000, the box Y that has been delivered from the side-angle holding portion 710 of the lower transport unit 700 and into which the article has been inserted rotates 90 degrees immediately below the delivery point. The rotation of the box is different from that in the first embodiment (see FIG. 6) after the box has been retracted to the rear from the delivery point to some extent.

  As shown in FIG. 24, the box Y is rotated in the box inverted portion (corresponding to the “discharge portion” in the claims) 1000 so that the opening portion that has been oriented in the lateral direction is directed upward. A rotating member 1010 is provided. The rotating member 1010 has a configuration similar to that of the L-shaped box discharge sheet 51 in the first embodiment, and is configured to be rotated 90 degrees around the fulcrum 1020 toward the downstream box discharge portion 1100.

  Here, as described above, when the size of the box Y is changed, the positions of the left, lower, and rear members are changed so as to correspond thereto. Therefore, the rotating member 1010 is configured such that the vertical position and the front-rear position can be changed. Since the delivery point of the box Y from the side angle holding part 710 of the lower conveyance part 700 is constant, for example, as shown in FIG. 25, in the case of a small box Y, the lower surface of the box Y at the time of delivery is more Since it is in a high position, the rotating member 1010 moves upward. Also, for example, as shown in FIG. 24, in the case of a large box Y, the rotating member 1010 moves backward because the rear surface of the box Y at the time of delivery is in a more rearward position.

  As shown in FIG. 26, the box inverted portion 1000 is provided with driving means 1030 for moving the rotating member 1010 up and down as described above, for example, a fluid cylinder, and driving means 1040 for moving back and forth, for example, a fluid cylinder. . Further, a driving means 1050 for rotating the rotating member 1010 by 90 degrees as described above, for example, a driving motor is also provided.

  On the other hand, the rotating member 1010 is divided into left and right two parts, which is also similar to the L-shaped box discharge sheet 51 in the first embodiment (see FIG. 5). When the size of the box Y is changed, the left rotation member 1010 is configured to be changeable in the left-right direction so as to correspond to the change. For example, in the case of a large box Y, the left surface of the box Y at the time of delivery is located on the left side, so the left rotating member 1010 moves to the left.

  As shown in FIG. 26, the box inverted portion 1000 is provided with driving means 1060, for example, a fluid cylinder, for moving the left rotating member 1010 left and right as described above. Then, the control unit 3000 is based on the information regarding the size of the box Y input from the input unit 1200, and the vertical position of both rotary members 1010, the front and rear positions of both rotary members 1010, and the left and right positions of the left rotary member 1010. The drive means 1030, 1040, and 1060 are controlled so as to be variably controlled.

  In addition to such a configuration, as shown in FIG. 24, the box inverted portion 1000 has a holding member 1080 that holds the box Y when the box Y rotates, and pushes the box Y to the downstream box discharge portion 1100 after the rotation. An extrusion member 1090 is further provided.

  The holding member 1080 has a pair of left and right, and holds the left and right side surfaces of the box Y delivered to the rotating member 1010 by sandwiching them from both the left and right sides. As shown in FIG. 26, the box inverted portion 1000 is provided with driving means 1081, for example, a fluid cylinder, for driving the holding member 1080 as described above. The operation of the driving unit 1081 is controlled by the control unit 3000.

  On the other hand, the pushing member 1090 is incorporated in both the left and right rotating members 1010. The pushing member 1090 provides a receiving surface (mounting surface) for the box Y when the box Y is transferred from the side-angle holding unit 710 of the lower conveyance unit 700. Then, after the rotating member 1010 has rotated 90 degrees, an appropriate driving means 1091 (see FIG. 26), for example, a fluid cylinder, projects and moves toward the downstream box discharge section 1100, thereby moving the placed box Y. It pushes and discharges to the box discharge part 1100 side. At this time, the holding of the box Y by the holding member 1080 is released. The operation of the driving means 1091 of the pushing member 1090 is also controlled by the control unit 3000.

[Features of this device]
In this apparatus, the box X is inserted into the box inverted portion 1000 and the box Y transferred from the side-angle holding portion 710 of the lower conveyance portion 700 is rotated from the lateral direction to the upward direction. Since it is discharged, the jumping out of the article X in the box Y is suppressed. Moreover, since the box Y rotates on the spot immediately after it is delivered, the jumping out of the article X in the box Y is further suppressed.

  Moreover, when the box Y is rotated in the box inverted portion 1000, the box Y is held by the holding member 1080, and after the rotation, the box Y with the opening portion facing upward is moved by the pushing member 1090. Since it is pushed out downstream, the box Y can be stably rotated at high speed and discharged, which can contribute to the improvement of the processing capacity of this apparatus.
