  However, in the automatic planting device of Patent Document 1, as a pre-process for setting a seedbed in the automatic planting device, a step of taking out the seedbed from a seedling container filled with water in order to germinate the seeds of the plants sown on the seedbed is required. However, since the nursery is made of a sponge-like material and is soft, it is difficult to automate the process of removing the nursery from the nursery container, and it must be done by human hands. There is a problem that the nursery is likely to be contaminated by sweat and bacteria attached to the bed.

  In addition, since the nursery bed is handled by grasping one block of the nursery bed from above with the insertion opening and closing tool, when inserting the opening and closing tool, the sprout of the plant that protrudes from the nursery bed is damaged by the insertion opening and closing tool. There is also a problem that there is a risk of losing.

  Conventionally, as shown in FIG. 8, a mat-shaped nursery bed B formed of urethane or the like and connected to a plurality of nursery beds B1 is known as a nursery for raising plants. In this nursery bed B, in order to make it possible to cut out each nursery bed B1 and operate it individually according to the growth state of the seedlings seeded in the seedling container B2 formed in each nursery bed B1, the thickness of the nursery bed B Adjacent nurseries B1 are partially connected at the center of each side of each nursery bed B1 by a connecting part B3 extending along the direction.

  However, in the above-described seedbed B, since the connecting part B3 is formed over the thickness direction of the seedbed B, when the seedbed B is set in a plant transplanting device and transplantation is performed mechanically, There was a problem that the nursery bed B1 could not be cut out smoothly.

  The present invention solves these problems, and provides a plant transplanting device that achieves quick and stable transplantation with a simple structure and low cost, prevents plant damage, and is easy to automate. It is for the purpose.

  The present invention relates to a plant transplanting device for transplanting a seedbed from a plant holder in which a plurality of holder seedbed holding parts penetrating in the vertical direction are arranged in a horizontal direction to a cultivation pallet having a pallet seedbed holding part penetrating in the vertical direction. A holder holding mechanism for holding the plant holder, a pallet holding mechanism for holding the cultivation pallet above or below a holder holding position by the holder holding mechanism, and a holder seedbed holding portion. A transfer mechanism for moving the held nursery bed in the vertical direction and inserting it into the pallet nursery holding unit, the transfer mechanism supporting the vertical movement unit movable in the vertical direction and the vertical movement unit The vertical movement portion has an engagement portion engageable with the nursery bed, and is opposed to the support portion around a rotation axis along the vertical direction. By provided rotatably Te, it is intended to solve the above problems.

According to the configuration of the first aspect of the present invention, by adopting a configuration in which the seedbed held by the plant holder is transplanted into the cultivation pallet, a plurality of nurseries are held at the time of setting the seedbed to the plant transplanting device. Since it is only necessary to set the plant holder in the state to the plant transplanting device, it is not necessary to directly handle the soft nursery bed, and the handling property of the nursery bed can be improved.
As a result, it is easy to automate the step of taking out the nursery bed from the nursery container, which is performed before setting the nursery bed on the plant transplanting device, because it is only necessary to take out the plant holder holding a plurality of nursery beds from the nursery container. In addition, since the automation is facilitated, it is possible to prevent the nursery from being contaminated by sweat or bacteria attached to humans.
Further, by transferring the nursery bed without grasping the soft nursery bed from above, it is possible to prevent a plant extending upward from the nursery bed from being damaged.
Moreover, while having an engaging part which can be engaged with a seedbed, the vertical movement part is provided so that rotation with respect to a support part centering | focusing on the rotating shaft along an up-down direction is carried out, and the pallet for cultivation By rotating the seed bed when inserting the seed bed into the pallet, even if the seed bed interferes with the edge of the pallet seed bed holding part of the cultivation pallet, the seed bed is deformed and smoothly inserted into the pallet seed bed holding part This also eliminates the need for precise alignment between the nursery and the pallet nursery holder. In addition, even if the size of the nursery bed is larger than the size of the pallet nursery holding part, it is possible to screw the nursery bed into the pallet nursery holding part, thereby improving the holding power of the nursery bed by the pallet nursery holding part be able to.
In addition, when the nursery bed is held by the plant holder and the nursery bed to be transferred and the nursery bed adjacent to the nursery bed are connected, the nursery bed is rotated when the nursery bed is extracted from the plant holder. Thus, the connection between the nurseries can be cut smoothly and reliably, and the nursery can be smoothly extracted from the plant holder.

According to the configuration described in claim 2, by providing the second vertical movement unit that is movable in the vertical direction independently of the vertical movement unit, after inserting the nursery bed into the pallet seedbed holding unit by the vertical movement unit, When retracting the vertical movement part, the second vertical movement part pushes the nursery bed, so that the engagement of the vertical movement part and the nursery bed is reliably released, and the nursery bed is moved to the pallet nursery with the vertical movement part. It is possible to avoid slipping out of the holding portion, and to reliably leave the nursery bed in the pallet nursery holding portion.
According to the configuration of the third aspect of the present invention, since the engaging portion is annularly arranged around the rotation shaft, the engaging portion of the vertically moving portion is engaged with the nursery bed in a balanced manner, It is possible to favorably rotate the nursery bed at the time of rotation of the moving part, and it is possible to avoid damage to the roots of the plant held on the nursery bed by the engaging part.
According to the configuration of the fourth aspect of the present invention, by moving the vertical movement portion in the vertical direction, the cam follower of the vertical movement portion is brought into sliding contact with the cam portion to control the rotation of the vertical movement portion, thereby moving up and down. Since it is possible to control the rotation of the vertical movement unit by using the vertical movement of the unit, it is possible to control the vertical movement with a simple configuration without providing a unique driving means for rotating the vertical movement unit. The moving part can be reliably rotated.
According to the configuration of the fifth aspect of the present invention, the vertical movement unit is configured to move up and down by configuring the vertical movement unit so that the seedbed held by the holder seedbed holding unit is pushed upward and inserted into the pallet seedbed holding unit. Since the nursery can be pushed up from below on a large surface by the part, a quick and stable transplantation can be realized with a simple structure.
According to the configuration described in claim 6, the vertical movement unit is configured so that the seedbed held by the holder seedbed holding unit is lowered downward and inserted into the pallet seedbed holding unit from above, thereby Even when the shoots of the sprouting come out from above the nursery and spread laterally, it is possible to avoid that the shoots of the plant are sandwiched between the pallet nursery holding part and the nursery. Moreover, since the up-and-down moving part grips the seedbed from the lower side of the seedbed, it is possible to avoid damaging the buds of the plant that has come out from the upper side of the seedbed.
