Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a nursery box cleaning device.

[Conventional technology]

An empty nursery box that has been used for raising seedlings has dirt and dust adhering to the inside, so it must be washed and cleaned before storing it. -1581
Like the one disclosed in Japanese Patent No. 51, the operator was allowed to successively stack the washed nursery boxes.

[Problems to be Solved by the Invention]

However, stacking a large number of nursery boxes manually is a labor-intensive task and is not satisfactory in terms of efficiency.

It is an object of the present invention to save labor and improve the work of cleaning a nursery box.

[Means for solving the problem]

The present invention is a loading unit for stacking an empty nursery box after being used for raising seedlings, a feeding unit for feeding one nursery box from the loading unit one by one, a conveyor for transferring the fed nursery boxes along a certain path, It is equipped with a washing section for washing the nursery box being transferred with water, a lifting transport section for lifting and transporting the washed nursery box diagonally upwards, and a stacking section, and the stacking section is inclined downward or downward in the transport direction. It is composed of a sheet-shaped transfer surface and a transfer frame that receives the seedling raising boxes dropped from the end of the transfer section on the transfer surface and stacks them up to a predetermined number of stages, and the transfer frame slides down due to the inclination of the transfer surface. It is characterized in that it has a rear wall that abuts the end of the nursery box in the direction of conveyance against the movement and receives it.

[Work]

(A) First, stack empty used nursery boxes on the loading section, and the feeding section will feed the empty nursery boxes one by one from the loading section, and the fed nursery boxes will be washed while being transferred by the conveyor. Part will wash away water and remove dirt and dust adhering to it. Since the seedling raising boxes after washing are stacked one above the other by the stacking section, a series of operations such as washing from the loading section of the seedling raising box to the stacking section and the setup process before and after that are automatically performed. .

(B) Since the shipping frame in the stacking unit is placed on the inclined transfer surface with the lower side in the transfer direction being the lower side, the seedling raising boxes that have been sent out from the end of the lifting transfer unit and have fallen are transferred to the lower transfer side due to the inclination of the transfer surface. Although it tries to slide down naturally toward, but is stopped by coming into contact with the rear wall of the shipping frame, the front and rear ends of the nursery box are stacked in an aligned state. In addition, if the shipping frame in which a predetermined number of the nursery boxes are stacked is released, the slanting of the transfer surface causes the nursery boxes to start to slide by themselves. As a result, for example, it becomes possible to move to the subsequent steps such as the packing section by itself without external force.

In addition, (c) Since the raising and transporting section conveys the seedling raising box to a higher position than the conveyor, the transfer surface height at the beginning of the conveyor does not fall too high at the height of the seedling raising box that has passed through the stacking section with height differences. Can be adjusted to.

〔The invention's effect〕

As a result, by the action of (a), it was possible to automate the work of stacking the nursery boxes after washing, which was conventionally covered by manual work, so labor was saved by labor saving and the washing work efficiency was improved. . Further, when the seedling raising boxes after washing are stacked in the collecting section by the action of (b), the tilting of the transfer surface allows the seedling raising boxes to be stacked in a state in which the motive force in the sliding direction acts on each seedling raising box. Since the front and rear ends of the seedlings are naturally aligned with high precision, the labor required for carrying the nursery box to the subsequent process can be saved, and the robot can be transferred to the subsequent process without any external force. Labor is also reduced. By the action of (C), the start and end portions of the cleaning device, which require manual work, can be set to the height positions that are easy to operate, and from this point as well, the labor can be reduced and the handling can be facilitated. It was possible to provide a more convenient and labor-saving seedling raising box cleaning device.
