Here, the suitability of the guide means may be selected depending on the state of the extended posture of the top surface flap extended from the opening of the box 6 opened sideways.

  As shown in FIGS. 2 and 3, the robot 10 employs a robot capable of high-speed processing, such as a parallel link robot, and is transported to the transfer position at the transport downstream end of the bag supply conveyor 8. Has a hand 19 that sucks and transfers it to the loading table 20. Two suction pads 19 a are attached to the hand 19.

  Each suction pad 19a sucks and holds the packed products 1 which are conveyed at predetermined intervals with the bottom portion directed forward in the conveying direction by the bag supply conveyor 8, and the two packed products 1 are placed above the input table 20. While being transported, the two packed products 1 are placed on the charging table 20 in a state where the bottom of the packed product 1 faces in front of the charging table 20 in the forward / backward direction.

  A predetermined gap S is provided between the packed products 1 when the two packed products 1 are sucked and held by each suction pad 19a and placed on the loading table 20. Then, the packaged product 1 is stacked in a plurality of stages on the charging table 20 as shown in FIG. Here, the packaged products 1 stacked one above the other are sequentially stacked so as to overlap each other in the upper stage in accordance with the gap S between the adjacent packaged products 1. Specifically, in the lowermost stage, the gap S between the adjacent packaged products 1 is made to correspond to the center of the trunk of the packaged product 1 so as to be stacked sequentially from above. In addition, about the clearance gap S, when not providing the clearance gap S, or when placing and arrange | positioning so that the seal | sticker part formed in the right and left of the packaging goods 1 in the adjacent right and left packaging goods 1 may mutually overlap. Corresponding to the size and other properties of the packaged product 1, it is appropriately handled. The number of stacking methods such as the number of stacking stages of the packaged product 1 and the number of the packaged product 1 held by the hand 19 by one transfer are not limited.

  Side guides 22 are provided on the left and right sides of the loading table 20 of each of the loading rows 12 and 13 in the packing unit 4 to restrict the movement of the packaged product 1 placed in the horizontal direction in the width direction. Yes.

  The charging table 20 is disposed below the bag supply conveyor 8 so as to move horizontally in the direction orthogonal to the bag supply conveyor 8, and the bag placement surface extends substantially horizontally. The extension end of the charging table 20 is appropriately inserted into the inside of the box 6 through the opening from a position spaced outward from the opening of the box 6 held by the box holding means 9 with the opening inclined in the horizontal direction. It is configured to be capable of advancing and retracting so as to extend to the charging position that is the one-way position.

  As shown in FIG. 4A, when a predetermined number of the packed products 1 are stacked on the input table 20, the input table 20 is advanced toward the opening of the box 6. The advancement speed of the charging table 20 at this time is such that the packaged product 1 does not slide on the bag placement surface on the charging table 20 and the stacked packaged product 1 does not collapse. The means 21 is controlled in operation.

  The charging table 20 moves backward immediately after its extended end extends to a position inward from the opening of the box 6. The position of the extending end when the input table 20 is extended preferably extends from the base of the top flap of the opening extending from the side panel of the box 6 to the vicinity of the center of the side panel extending from the bottom of the box 6 to the bottom of the box 6. When the bag 1 is sequentially put into the box 6, the next bag 1 to be dropped at least on the top of the bag 1 accommodated in the box 6 may be dropped. It is set appropriately so that it can be done. When the height of the bag 1 is lower than the height of the normal bag 1 with respect to the height from the bottom surface of the box 6 to the top surface, the rotation amount of the servo motor as the driving means is increased, By extending the charging table 20 into the box 6 more inward than usual, it becomes possible to reliably drop the next packed product 1 onto the top of the already-packed packed product 1. The input means 20 may control the operation of the driving means 21 so as to move backward after a predetermined timing after reaching the extended end.

  By retracting the extended charging table 20 as shown in FIG. 4 (b), the packaged product 1 having a relatively heavy weight, such as a liquid filling, stacked on the charging table 20 is While moving forward under the inertial force at the time of extension, the support on the lower surface side by the input table 20 is released, falls into the box 6 and slides along the side panel located at the bottom of the box 6. The packaged product 1 reaches the bottom of the box 6 in a laminated state. It is preferable to set the retraction speed of the charging table 20 at a high speed so as to release the support of the bag 1 immediately. When the bag 1 is moved forward, the bag 1 is moved forward at a speed set lower than the reverse speed that does not disturb the stacking state stacked on the input table 20, and then the bag 1 stacked when the reverse is moved. The support of the bottom surface is released all at once and the packed state is not disturbed, and the packaged product 1 can be reliably packed so as to reach the bottom of the box 6. The bag-packed product 1 has a form in which the center of gravity is offset from the bottom of the bag, and the bag is stacked in a posture lying sideways on the charging table 20 with the bottom side of the bag facing forward in the extending direction of the charging table 20. And since the accumulated bag products 1 are thrown into the box 6 from the bottom side of the bag having a heavy weight in the front, a plurality of bag products 1 are not disturbed. Reaches the bottom of the box 6 well.

  When the first insertion into the box 6 is completed in the first input row 12 in this way, the box holding means 9 retracts the elevating arm 15 of the support means 16 and the next of the section below the partition 6a. The holding height of the box 6 is lowered corresponding to the stacking height.

  The bag loading means 11 is a zigzag pattern in which the bagging product 1 to be loaded next stacked on the loading table 20 is stacked on the bagging product 1 previously stacked in the box 6 as described above. It is thrown so that it may become the integration state which becomes arrangement | positioning. The bag 1 to be loaded with the support on the bottom side released is slid on the upper surface of the bag 1 already stacked in the box 6 in the accumulated state and reaches the bottom of the box 6. In the present embodiment, when the filling up to the height of the partition 6a is completed, as shown in FIG. 4C, the next stacked bag 1 is put on the partition 6a as described above. The operation of lowering the holding position of the box 6 and the operation of loading the accumulated bag 1 are repeated a predetermined number of times, and the packing of the bag 1 is completed in the first loading row 12.

  Next, the box holding means 9 extends the raising / lowering arm 15 of the support means 16 and rotates the rotating arm 14 so that the box conveying means on the opposite side of the bag holding means 9 with the box holding means 9 interposed therebetween. The box 6 transferred to the box holding position in FIG. 7 is placed with its opening facing upward, and the suction holding by the holding part 17 is released.

  In the second input column 13, the same operation as the boxing process in the first input column 12 is also performed in parallel at different timings. In the case of two input rows 12 and 13 as in the present embodiment, during the input operation of the packed product 1 by one of the first or second input rows, the input table 20 is input to the other input row. The placing operation of the packaged product 1 is performed.

This embodiment has the following effects.
(1) In the bag loading means 11, the loading table 20 on which the packaged product 1 is laid in a predetermined direction is advanced by a driving means 21 such as a servo motor, and is extended inward from the opening of the box 6. And then retracted to release the support of the lower surface of the bag 1 by the input table 20 and drop the bag 1 so that the bottom of the bag 1 is lower than the opening of the box 6. The bottom of the box 6 held in an inclined state so as to be on the side can be brought in a forward inclined posture. Therefore, when packing the packed product 1 having the center of gravity set on the bottom side of the bag, such as a self-supporting container, in a packed state, the size of the packed product 1 or the box 6 or the number of stacking stages of the packed product 1 or other accumulations. It is possible to provide a boxing device having a simple configuration that can flexibly cope with a change in form.

  (2) In the bag loading means 11, the driving means 21 such as a servo motor can be set so that the moving speed when the loading table 20 moves backward is high. It can be released instantly. Since the servo motor can easily adjust the moving speed at the time of forward movement and the moving speed at the time of backward movement, it is possible to stably put the packed bag 1 in the box 6 without being disturbed.

  (3) The robot 10 places a gap S between the adjacent ones 1 on the charging table 20 and places the next one to be stacked corresponding to the gap S. It is possible to flexibly cope with a desired accumulation state, such as placing them, arranging the packed products 1 without leaving the gap S, or stacking the side-by-side packed products 1 so as to partially overlap. Further, the number of stacking stages of the bag 1 on the input table 20 and the number of times of charging into the box 6 can be appropriately set according to the size of the bag 1 and the bag form.

  (4) Since the box holding means 9 holds the box 6 in an inclined posture in which the bottom of the box 6 is lowered obliquely when the packaged product 1 is charged, the charging table 20 is moved to the vicinity of the bottom of the box 6. Without extending, the packed product 1 having the front center of gravity put into the box 6 is inclined forward so that it slides on the inclined surface from the falling position to the bottom of the box 6. The boxed product 1 can be satisfactorily packed without disturbing the accumulation state.

  (5) Since the extension end position when the input table 20 is extended is set to be changeable, the packaged product 1 corresponds to the properties such as the size and form of the packaged product 1 and other various packaging conditions. Can be brought to the bottom of the tilted and held box 6 without disturbing its accumulation state.

  (6) When the robot 10 places and stacks the packed products 1 in the input rows 12 and 13, the stacked packed products 1 that are stacked one above the other are arranged in a staggered manner. The size of the box 6 to be accommodated can be reduced.

  (7) The position from the rotation fulcrum of the holding part 17 supported rotatably between the box conveying means 7 and the loading table 20 to the holding part 17 is as follows. , The box 6 received from the box conveying means 7 can be packed in a simple manner without going through a plurality of mechanisms until the box 6 is returned to the box conveying means 7, and the box conveying means Since the box 6 held at the holding position 7 is in a holding state until the boxing is completed, it is not necessary to provide a guide or the like for positioning the box 6 by delivery to another.

  (8) By providing a plurality of input rows 12 and 13, while the box 6 is being replaced after completion of boxing in any of the input rows, the box 6 positioned up to the input position of the other input row Since the packaged product 1 can be loaded, the boxing operation can be efficiently performed by the parallel processing.

The present invention can be modified as appropriate in addition to the above-described embodiments and other examples in the embodiments without departing from the spirit of the present invention. For example, the following configurations can be adopted.
As shown in FIG. 4 (c), in the relatively light bag-packed product 1, a push-in member that reciprocates in the advancing and retreating direction of the charging table 20 by a driving unit 23 such as an air cylinder. 24 is preferably disposed. The bag 1 placed on the loading table 20 is configured to push the upper side of the bag disposed on the rear side toward the opening of the box 6 held at the loading position by the pushing member 24. . Then, while the bagging product 1 is forcibly pushed toward the opening of the box 6 by the pushing member 24, the charging table 20 is moved backward. The pushing member 24 may be operated so that only the pushing member 24 is stopped behind the packaged product 1 and the packaged product 1 is scraped out when the charging table 20 is retracted. In this way, the bagged product 1 on the loading table 20 is pulled back by the loading table 20 as the loading table 20 is retracted, and the state of accumulation of the bagged product 1 is disturbed when dropped. Can be prevented in advance and can be securely packed in a box.

  Although the holding height of the box 6 with respect to the charging table 20 is displaced by moving the lifting arm 15 of the support means 16 up and down, the charging table 20 is linked to appropriate drive transmission means such as a crank mechanism and a rack and pinion mechanism. It is only necessary that the loading table 20 and the holding height of the box 6 at the loading position are relatively displaced by raising and lowering by a driving means such as a servo motor.

  -The inclination angle at the loading position of the box 6 held with the opening of the box 6 facing the extended end of the loading table 20 depends on various properties such as the form, size and weight of the bag 1 The holding angle of the box 6 by the means 9 can be changed and adjusted. It should be noted that the rotation amount of the servo motor, which is a driving means, is changed and adjusted so that the extended end position when the input table 20 is extended is changed in accordance with the inclination angle of the box 6 held at the input position. it can.
