Then, it is driven to move between the right and left support portions 4 (see FIGS. 8 and 9).

[6]
Next, the overall operation flow of the seedling box processing facility will be described.
In the state shown in FIGS. 1, 2, and 3, four sets of seedling boxes 1 that are stacked are placed on the stacking unit 2, and an empty greening cart 5 is positioned at a predetermined position of the guide rail 33 (the support unit 4 at the center, And a predetermined position adjacent to the left support portion 4). In this state, the holding unit 19 (nursery box separation mechanism 3) is positioned above the four seedling boxes 1 stacked, and the central support unit 4 and the right and left support units 4 are in the upper receiving position. The pusher 16 is located at the retracted position. As shown in FIGS. 4, 5, and 6, with the guide mechanism 21 having a predetermined length, the lower end of the conical portion 21 a of the guide mechanism 21 and the opening portion 24 a of the connection portion 24 are matched to each other, and the holding portion 19 Is in a state in which it cannot move laterally from a predetermined position in the lateral direction.

  As shown in FIGS. 14 and 15, when the empty green cart 5 is arranged at a predetermined position of the guide rail 33 (a predetermined position adjacent to the central support portion 4 and the right and left support portions 4), FIG. As shown, for example, the operator pushes the empty greening cart 5 (the wheels 5h of the empty greening cart 5 are on the front side, and the caster wheels 5i of the empty greening cart 5 are on the rear side (worker side)), The wheel 5h of the greening cart 5 is placed on the guide rail 33. When the operator further pushes the empty greening cart 5, the locking portion 5 j of the empty greening cart 5 rides on the guide member 68, and the caster wheel 5 i of the empty greening cart 5 is slightly lifted from the guide rail 33. In this case, the locking portion 5j of the empty greening cart 5 does not enter the gap between the engaging portions 67d of the endless rotating body 67, and the bottom portion 5a of the empty greening cart 5 is also the guide member 68 and the endless rotating body 67. There is no contact with the engaging portion 67d.

As shown in FIG. 16, when the operator further pushes the empty greening cart 5, the locking portion 5j of the empty greening cart 5 is disengaged from the rear part of the guide member 68, and the caster wheel 5i of the empty green cart 5 is moved. It falls on the guide rail 33, and the locking part 5j of the empty greening cart 5 fully enters the gap between the engaging parts 67d of the endless rotating body 67 (or the locking part 5j of the empty greening cart 5 rotates endlessly). Since it is on the upper end of the engaging portion 67d of the body 67, as will be described later, when the endless rotating body 67 starts to be rotated in the clockwise direction in FIG. 16, the locking portion 5j of the empty greening cart 5 becomes the endless rotating body. 67 sufficiently enter the gap between the engaging portions 67d).
In this case, the caster wheel 5i of the empty greening cart 5 is placed on the guide rail 33 so that the caster wheel 5i of the empty greening cart 5 is located on the front side and the wheel 5h of the empty green cart 5 is located on the rear side. The same operation as described above may be performed.

  Thereafter, when the carriage transport mechanism 34 is actuated (when the endless rotating body 67 is driven to rotate clockwise in FIG. 16), the empty greening carriage 5 (locking section 5j) is engaged by the engaging portion 67d of the endless rotating body 67. Is pushed to the right in FIG. 14 and FIG. 15, and the empty green cart 5 reaches a predetermined position of the guide rail 33 (a predetermined position adjacent to the central support portion 4 and the right and left support portions 4). The carriage transport mechanism 34 (endless rotating body 67) automatically stops.

  In this case, there is a possibility that the caster wheel 5i of the greening cart 5 may swing in the direction intersecting the guide rail 33 (vertical direction in FIG. 14) with the caster wheel 5i of the empty greening cart 5, but endless rotation The friction between the engaging portion 67d of the body 67 and the locking portion 5j of the empty greening cart 5 suppresses the state in which the vicinity of the caster wheel 5i of the empty greening cart 5 swings. As shown in FIGS. 9 and 12, since the movable guide members 56 of the right and left support portions 4 are located at the retracted positions and do not protrude toward the greening cart 5 side, the empty greening cart 5 is set to a predetermined position on the guide rail 33. When moving to a position (predetermined position adjacent to the center support portion 4 and the right and left support portions 4), the greening cart 5 is in contact with the movable guide member 56 of the right and left support portions 4. Absent.

[7]
Following the preceding item [6], as shown in FIG. In the four seedling boxes 1 stacked, as shown in FIGS. 4, 5, and 6, the upper seedling box 1 comes into contact with the guide rod 26 to push up the holding portion 19, and the guide mechanism 21 and the connection mechanism 25 is in a state of contracting from a predetermined length. In this case, the holding member 27 is driven by the drive rod 28a of the drive mechanism 28 to a holding release position that is outwardly separated from one and the other side edges of the upper nursery box 1, and the holding member 27 is driven by the guide rod. The holding member 27 is returned to a predetermined reference posture parallel to one end and the other end of the holding portion 19 by contacting the 26 stoppers 26a.

  As shown in FIGS. 4, 5, and 6, when the holding portion 19 is pushed up by the upper seedling box 1 and the guide mechanism 21 contracts from a predetermined length, the conical portion 21 a and the flange portion 21 b of the guide mechanism 21 are connected to each other. The guide mechanism 21 (guide rod 21d) is separated from the opening 24a of the guide 24 and enters the inside of the connection portion 24 within the range of interchangeability between the guide rod 21d of the guide mechanism 21 and the opening 24a of the connection portion 24. The holding part 19 is allowed to move in the lateral direction. In the connection mechanism 25, the holding portion 19 moves in the lateral direction with respect to the connection mechanism 25 (connection rod 25 a) within the range of interchangeability between the connection rod 25 a of the connection mechanism 25 and the opening 18 a of the upper support portion 18. Permissible. Thereby, the holding | maintenance part 19 moves to a horizontal direction or inclines from the predetermined position of a horizontal direction so that the upper seedling box 1 may be followed.

Next, the drive rod 28a of the drive mechanism 28 is contracted, and the holding member 27 is pressed against one and the other end of the upper nursery box 1 (the sponge member 27a of the holding member 27 is the upper nursery box 1). The support pins 27b of the holding member 27 enter the lower side of the edge of the upper nursery box 1 and the upper four nursery boxes 1 are held by the holding part 19 (holding of the holding member 27). position).

  In this case, even if the upper seedling box 1 is inclined in plan view with respect to the holding unit 19, the drive mechanism 28 is driven as the holding member 27 is driven from the holding release position to the holding position side. The holding member 27 swings around the longitudinal axis P3 of the rod 28a, and the holding member 27 is pressed along one and the other end sides of the upper nursery box 1. Furthermore, the holding part 19 is forcibly moved in the lateral direction with respect to the upper nursery box 1 by a reaction force caused by pressing the holding member 27 against one and the other side of the upper nursery box 1. Then, the holding unit 19 moves in the horizontal direction from a predetermined position in the horizontal direction so as to better follow the upper nursery box 1.

  As shown in FIGS. 4, 5, and 6, when the stacking unit 2 is driven downward, the holding unit 19 is driven downward together with the upper seedling box 1, and the guide mechanism 21 and the connection mechanism 25 extend to guide When the nut 21c of the mechanism 21 reaches the upper support portion 18 and the stacking portion 2 is further driven downward, the holding portion 19 is moved sideways by the guide action of the conical portion 21a and the connection portion 24 of the guide mechanism 21 and the opening portion 24a. Returned to a predetermined position in the direction (see FIG. 4). As a result, the guide mechanism 21 and the connection mechanism 25 reach a predetermined length, and the holding unit 19 cannot move from a predetermined position in the horizontal direction in the horizontal direction.

  As shown in FIGS. 4, 5, and 6, the stacking unit 2 is further driven downward, and the holding unit 19 separates the upper seedling box 1 from the stacked seedling box 1, and the stacking unit 2 stops. In this case, the operation unit 29a of the separation mechanism 29 is repeatedly projected obliquely downward at a high speed, and the seedling box 1 in the lower stage of the upper seedling box 1 held by the holding unit 19 is the operation unit of the separation mechanism 29. By pushing downward by 29a, the upper nursery box 1 and the stacked seedling boxes 1 are forcibly separated.

  As described above, when the four seedling boxes 1 are held by the holding unit 19, as shown in FIG. 1, the holding unit 19 holding the four seedling boxes 1 is placed on the right side of the sheet of FIG. It is driven to move and stops above the support part 4 at the center of the receiving position and the right and left support parts 4. Next, the center support portion 4, the right and left support portions 4 are driven up, and the center support portion 4 and the right and left support portions 4 contact the four seedling boxes 1 held by the holding portion 19. The four seedling boxes 1 held by the holding unit 19 are pushed up.

  As a result, when the detection members 22 are pushed up by the four holding portions 19 and the upper ends of all the detection members 22 are detected by the proximity sensor 23, the central support portion 4 and the right and left support portions 4 are stopped. . The drive rod 28a of the drive mechanism 28 shown in FIGS. 4, 5, 6 is extended and the holding member 27 is separated from the seedling box 1 (the sponge member 27 a and the support pin 27 b of the holding member 27 are separated from the seedling box 1. As shown in FIG. 1, the four seedling boxes 1 held by the holding unit 19 are moved to the central support unit 4 and the right and left support units 4. When the holding member 27 is driven to the holding release position in this way, the holding member 27 comes into contact with the stopper 26 a of the guide rod 26, and the holding member 27 is parallel to one and the other end sides of the holding portion 19. It is returned to a predetermined reference posture (see FIGS. 4, 5, and 6).
