Corresponds to. These panels are not used in the transplant device 1 in this example. That is, it can be said that the transplant device 1 is a test device (prototype), but as will be described later, the points of the present invention are also incorporated in this example.

Various members of the transplanting device 1 are made of a metal such as stainless steel, but the material thereof is not particularly limited. Further, the structure, shape, positional relationship, etc. of various members are not particularly limited.

FIGS. 4 to 6 show an extruder 4 arranged below the seedling holding device 6. The extrusion device 4 presses the nursery bed piece C from the side of a part of the nursery bed piece C gripped by the gripping device 10 (see FIGS. 7 to 11) as described later, and holds the nursery bed piece C in the first holding portion. Extrude from 62. In this example, the gripping device 10 grips a part exposed from the lower surface of the first holding portion 62, and the extrusion device 4 presses the nursery piece C from below the first holding portion 62 to control the nursery bed. Move piece C upward.

The extrusion device 4 has a drive unit 41, a support unit 43, and a plurality of elongated rod-shaped members 45 that press the lower surface of the nursery piece C. The drive unit 41 drives the support unit 43 and the rod-shaped member 45 in the vertical direction. The support portion 43 supports the root of the rod-shaped member 45. The tip of the rod-shaped member 45 comes into contact with the lower surface of the nursery piece C when ascending, and presses the nursery piece C upward.

7 to 11 show a gripping device 10 arranged below the seedling holding device 6. The gripping device 10 serves to grip a part of the nursery piece C exposed from the holding portion (first holding portion 62) of the seedling holding device 6 while compressing it from both sides. In this example, the gripping device 10 grips a part of the nursery piece C exposed from the lower surface of the first holding portion 62 from both sides.

The gripping device 10 has a gripping claw driving unit 11 and a set of gripping claws 13 facing each other, and the gripping claw driving unit 11 drives a set of gripping claws 13 to approach or separate from each other. A set of gripping claws 13 sandwich the nursery piece C by approaching each other from both sides of the nursery piece C. At this time, the nursery piece C is compressed, the two sides are brought closer to each other, and the nursery piece C is contracted in the radial direction.

FIG. 7 shows the gripping device 10 in the first step, and in this state, the gripping claw 13 of the gripping device 10 is separated from the lower surface of the nursery piece C. 8 and 9 show the gripping device 10 in the second step. From the state of FIG. 7, the gripping claw driving unit 11 and the gripping claw 13 move upward, and the gripping claw 13 moves to the lower surface of the seedling holding device 6. Adjacent.

10 and 11 show the gripping device 10 in the third step, and from the state of FIGS. 8 and 9, the gripping claw driving unit 11 drives a set of gripping claws 13, and the lower surface of the first holding portion 62.

A set of gripping claws 13 sandwich the nursery piece C by approaching each other from both sides of the nursery piece C. At this time, the nursery piece C is compressed, the two sides are brought closer to each other, and the nursery piece C is contracted in the radial direction.

The gripping claw 13 has an arc-shaped contact surface 13a that contacts the side surface of the nursery piece C. When the two contact surfaces 13a approach each other when the nursery piece C is compressed, the cross section of the nursery piece C becomes substantially circular and shrinks in the radial direction of the cross section. In this state, as shown by the broken line in FIG. 10, the tip of the rod-shaped member 45 raised in the direction of arrow B by the drive unit 41 comes into contact with the lower surface of the nursery piece C and presses the nursery piece C upward.

The nursery piece C made of an elastic material such as polyurethane foam is inserted into the first holding portion 62 formed by the holes, and the inserted portion is pressed and shrunk in the radial direction of the cross section. On the other hand, the portion of the nursery piece C exposed from the first holding portion 62 tends to expand in the radial direction. When the nursery piece C is not compressed by the gripping claw 13, even if the extruder 4 presses the nursery piece C from below the first holding portion 62, the expanded portion interferes with the first holding portion 62. , It becomes difficult to smoothly move the nursery piece C upward, which may hinder the smooth transplanting work.

In the present embodiment, as shown in FIGS. 10 and 11, the portion of the nursery piece C exposed from the lower surface of the first holding portion 62 is compressed in the radial direction by the gripping device 10, and the first holding portion 62 is compressed. The size is close to the diameter of the hole to be formed. Therefore, when the extrusion device 4 presses the nursery piece C from below the first holding portion 62, the nursery piece C can be smoothly pushed out from the first holding portion 62, and the efficiency of the transplanting work deteriorates. Can be prevented.

In particular, in the present embodiment, the two contact surfaces 13a approach each other when the nursery piece C is compressed, so that the cross section of the nursery piece C becomes substantially circular and shrinks in the radial direction of the cross section. The first holding portion 62 is a portion corresponding to a hole in the cultivation panel, and the hole in the cultivation panel is often formed in a circular shape. Due to the action of the two contact surfaces 13a, the cross section of the nursery piece C becomes substantially circular, which is the same as the hole in the general cultivation panel. Therefore, even when the nursery piece is extruded from the hole in the cultivation panel, it can be extruded smoothly. it can. However, the shape, position, etc. of the gripping device 10, the gripping claw 13, and the like are not particularly limited.

Further, the transplanting device 1 separates the nursery bed piece C from which the nursery bed piece C extruded from the first holding portion 62 is grasped and taken out after the steps of FIGS. 7 to 11 and the nursery bed piece C is driven to drive the taking out device 7. It is provided with a moving device 8 for moving to the location of. The take-out device 7 is supported by a rail-shaped moving device 8 so as to be horizontally movable. The take-out device 7 is arranged above the seedling holding device 6 and has a take-out claw 71 (see FIGS. 2 and 3). The take-out claw 71 grips both sides of the nursery piece C extruded from the first holding portion 62 and takes out upward. After taking out the nursery piece C, the moving device 8 is driven to move the taking-out device 7 holding the nursery piece C in the direction of arrow A in FIG. 3, and the position of the second holding portion 64, which is another place described above. Move the nursery piece C to.

After that, the pull-in device 5 arranged below the seedling holding device 6 moves upward, passes through the second holding portion 64, grips the nursery piece C, and pulls downward to pull the nursery piece C into the second. It is arranged in the holding portion 64. The retracting device 5 has the shape of a clamp pin, but the shape is not particularly limited.

The second holding portion 64 corresponds to a hole provided in the second cultivation panel in which the nursery piece C is newly arranged. Through the series of operations described above, the transplanting device 1 transplants the nursery piece C from the first holding portion 62 to the second holding portion 64. This work corresponds to the work of transplanting the nursery piece C from the hole of the first cultivation panel to the hole of the second cultivation panel in a practical situation. Since the transplanting device 1 of this example is mainly used for the test, the seedling holding device 6 is used, but the series of configurations described can also be used in a practical transplanting device. That is, the transplanting device 1 has a plurality of holes corresponding to the second holding portion 64 from the cultivation panel (first cultivation panel) in which a plurality of holes corresponding to the first holding portion 62 are arranged in the nursery piece C. Needless to say, it can be applied to the work of transplanting to the arranged cultivation panel (second cultivation panel).

12 to 14 show another example of the extruder 4. The extruders of FIGS. 4 to 6 have six simple rod-shaped rod-shaped members 45, whereas the extruder 4 of FIGS. 12 to 14 has two rod-shaped members 47 having a semicircular cross section. have. However, the shape, position, etc. of the extruder 4, the rod-shaped member, and the like are not particularly limited.

In the above description, the transplanting apparatus 1 transfers the nursery pieces of the seedlings of the plant grown to some extent from one cultivation panel (first cultivation panel) to another cultivation panel (second cultivation panel). It is used for replacement work. However, the transplanting device 1 is used not only for such work, but also for the work of transferring a nursery piece divided from a nursery sheet such as urethane foam in which seeds are first planted to a cultivation panel. "Transplant" in the book means to include these two tasks.

The present invention is not limited to the above-described embodiment, and can be appropriately modified, improved, and the like. In addition, the material, shape, size, numerical value, form, number, arrangement location, etc. of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.
