2. Description of the Related Art Conventionally, as an apparatus for arranging seedling boxes as described above, for example, a plurality of groups of seeded seedling boxes are stacked in the rear part of the apparatus in a stacked state, and a plurality of seedling boxes are stacked in the rear part of the apparatus. The seedling boxes of the group are separated one by one from the upper side, and the seedling boxes are sequentially transferred onto a conveyor erected in front of the apparatus. After placing a predetermined number of seedling boxes in the longitudinal direction on the left and right mounting surfaces of the conveyor and placing them, the entire conveyor is rocked obliquely downward and the entire seedling box is laid in the longitudinal direction. There is a device for arranging on a surface (Japanese Patent Laid-Open No. 5-316879).

[0003]

However, in the above-described apparatus, when transferring a plurality of groups of seedling boxes stacked at the rear of the apparatus to a conveyor, the seedling boxes stacked at the top are slid in the longitudinal direction. Since each stage is separated, at the time of separation, the bottom part of the seedling box stacked on the top is easy to fit into the seedling box stacked on the lower side, and the soil and seeds etc. stored in the seedling box There is a problem that the seeding state is liable to fluctuate because the stored items may be discharged to the outside of the box. Also, the storage amount of soil and seeds is reduced,
If the stored items are offset, the growth of the seedlings is impaired, and the amount of growth is reduced, so that there is a problem that it is difficult to maintain the storage state of the soil and seeds stored in the seedling box. ing.

Further, since the left and right conveyors connected to the front of the apparatus are horizontally rotated and the conveyors are folded so as to be parallel to both side surfaces of the apparatus main body, the left and right conveyors are longer than the entire length of the apparatus main body. When the device is used indoors or in a facility, not only the range of movement is restricted, but also a large space is required for moving and storing the device itself, and depending on the place of use, There is a problem that the left and right conveyors must be removed, which is inconvenient to handle.

In view of the above-mentioned problems, the present invention transposes a large number of containers from a transport trolley to a container separation section while keeping the containers at equal intervals in the vertical direction, separates the containers from the lower side, and places the containers on the container alignment section. Since the containers placed on the container alignment section are arranged on the laying surface while moving the apparatus body, the work time required for arranging the containers is greatly reduced, and a container arrangement device capable of improving work efficiency is provided. With the goal.

According to the container arrangement device of the present invention, for example, a transport cart in which a large number of containers are shelved at equal intervals in the vertical direction,
After loading on the carriage loading section of the apparatus main body by manual or mechanical work, the transfer means is driven to transfer the containers shelved in the transport carriage to the container separation section. The container transferred to the container separating unit is separated from the lower stage side and fed to the container aligning unit, and the container arranging unit is driven, and the containers aligned in the container aligning unit are arranged on the laying surface, and the apparatus moving unit is moved. When driven, the apparatus main body is moved at a constant speed or intermittently moved, and the containers are sequentially arranged on the laying surface, so that, for example, the storage state of the soil and seeds stored in the seedling raising box fluctuates or germinates. Alternatively, it is possible to reliably prevent the greened seedlings from being bent, and the seedling boxes can be sequentially arranged on the laying surface while maintaining the state at the time of shelving.

According to a second aspect of the present invention, in addition to the operation of the first aspect, the container arranging device drives the container allocating means,
The containers separated by the container separation unit are alternately distributed to the left and right mounting surfaces of the container alignment unit, or are allocated before one of the mounting surfaces, and are allocated after the other mounting surface. The containers can be aligned and mounted equally on the left and right. For example, the structure and mechanism for distributing containers by rotating the conveyor in the normal and reverse directions are not required, and the container distributing operation can be performed simply and easily.

According to a third aspect of the present invention, in addition to the operation of the first aspect, the container arranging device is configured to rotate the side conveyor constituting the container aligning section to a horizontal posture that is horizontal with respect to the central conveyor. In addition, since the containers separated by the container separating unit are sorted on the central and side conveyors, a large number of containers can be arranged on the laying surface in a lump. At the time of movement and storage, the side conveyor is rotated to a standing posture that stands upright with respect to the central conveyor, so that the space for moving and storing the apparatus main body is small, and the handling of the apparatus is easy.

[0012]

According to the present invention, after the containers put on the carrier cart are transshipped to the container separating section, the containers transferred to the container separating section are separated from the lower side and fed to the container aligning section. Therefore, at the time of separation, for example, it is possible to reliably prevent the state of storage such as soil cover and seeds stored in a container such as a seedling raising box from fluctuating, and prevent germinated or greened seedlings from bending. The containers can be arranged on the laying surface while maintaining the state at the time of putting. Further, the operation time required for the separation and arrangement of the containers is greatly reduced as compared with the case where a large number of containers are separated from the upper side as in the conventional example, and the efficiency of the operation can be improved. Since the containers arranged in the container alignment section are arranged on the laying surface, a large number of containers can be arranged at once, and the laying space can be effectively utilized.

In addition, since the containers separated by the container separating unit by the container sorting means are distributed and supplied to the left and right mounting surfaces of the container arranging unit, a predetermined number of containers can be aligned and mounted uniformly on the left and right sides. For example, the structure and mechanism for distributing containers by rotating the conveyor forward and backward become unnecessary,
Sorting of containers can be performed easily and easily. In addition, by raising the side conveyor that constitutes the container alignment section during movement and storage, the space for moving and storing the apparatus main body can be reduced, and the apparatus can be easily handled.
