Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shelving device used in a seedling raising facility for intensively growing a large number of seedlings for a rice transplanter. More specifically, the present invention relates to a stacked seedling box in which seedling boxes are stacked in multiple stages and germinated. The present invention relates to a seedling insertion device used for inserting each seedling raising box of a unit into a greening shelf with a predetermined vertical interval.

[0002]

2. Description of the Related Art As the above-mentioned shelving unit, for example, a stacking nursery box unit in which seedling boxes are stacked in 20 to 30 tiers and sprout-processed is supplied to a one-box separation mechanism, and the lowermost one of the stacking nursery box units is used. Separately send out the boxes one by one, supply the seedling boxes sent out to the lift mechanism, receive and hold one box at a time with a predetermined interval above and below, and sequentially pump upwards. In the completed state, the seedling box group held by the lift mechanism is pressed and carried out horizontally at a stroke by the push-out mechanism, and is inserted into a shelf of a greening shelf that has been previously arranged on the exit side of the lift mechanism. Things have been put to practical use.

[0003]

The shelving device having the above configuration has the following problems. That is, since the seedling boxes are separated one by one from the stacked seedling box unit and supplied to the lift mechanism, the overall processing speed is determined by the processing speed of the single box separation mechanism. However, there is a limit in increasing the processing speed, and it is difficult to increase the processing capacity per unit time. The seedling box units that have been germinated and stacked in multiple stages are mounted on the seedling box unit supply mechanism and supplied to the single box separation mechanism, but in general, the transport surface of the seedling box unit supply mechanism is higher than the floor of the workplace. It is located several tens of cm higher, and the lift mechanism and the push-out mechanism are configured to operate at a height corresponding to this. On the other hand, the greening shelf has a bogie structure with idle wheels so that it can travel on the floor of the workplace, and several shelves on the floor at the lower end of the greening shelf are placed on the floor. Is located lower than the lowest seedling box extruded from the extrusion mechanism. Therefore, in order to adjust the height of the greening shelf to the height of the extrusion mechanism, the greening shelf is configured to be raised to the height of the extrusion mechanism by a dedicated lifting mechanism, and before the shelf insertion work, an empty greening shelf is When the table is lifted from the floor to the working height, and the shelf is placed on the greening shelf, a greening shelf raising and lowering process for lowering the greening shelf from the working height to the floor is required, which has been a loss of work time.

The present invention has been made in view of such a situation, and has as its object to enhance the efficiency of the entire shelving operation.

A single box separation mechanism, a plurality of lift mechanisms for receiving and holding the seedling boxes sent from each single box separation mechanism one by one at predetermined intervals above and below, and sequentially lifting the seedling boxes upward, and each lift The mechanism is characterized in that the mechanism is provided with a push-in mechanism that inserts a predetermined number of seedling box groups held at a vertical interval into the greening shelf at once.

(Action) According to the above configuration, the stacked seedling raising box unit is once divided into a plurality of seedling raising box blocks,
The one-box separation processing by the one-box separation mechanism and the sequential lifting processing by the lift mechanism are performed in parallel for each block.

(Effects) Therefore, according to the first aspect of the present invention, even if there is a limit to the increase in the processing speed of the one-box separation mechanism, the processing speed as a whole will increase, and the shelf-mounting work will be increased. The efficiency can be improved.

[Structure, operation and effect of the invention according to claim 2]

(Structure) The invention according to claim 2 is for inserting each seedling box of the stacked seedling box unit in which seedling boxes are stacked in multiple stages and subjected to germination, into a greening shelf with predetermined vertical intervals. A seedling box unit supply mechanism for placing and transporting the stacked seedling box units, and a separate box for feeding the seedling boxes of the stacked seedling box units carried in by the seedling box unit supply mechanism. A box separation mechanism, and a lift mechanism for receiving and holding the seedling boxes sent out from the one box separation mechanism at a predetermined interval vertically and one by one and sequentially lifting the seedling boxes upward, and a predetermined number of seedling raising seedlings. In a state where the box is received and held, the lift mechanism is configured to be capable of being driven to rotate in the reverse direction until the lowermost seedling box is positioned lower than the transport height of the seedling box unit supply mechanism, and the lift mechanism is held. The present invention is characterized in that a push-in mechanism is provided for inserting a predetermined number of nursery box groups held and lowered at once into a greening shelf provided on the floor of a work place.

(Operation) According to the above configuration, when a predetermined number of nursery boxes sent out from the one-box separation mechanism are received by the lift mechanism at predetermined vertical intervals, the height corresponding to the greening shelf provided at a low position is adjusted. , The lift mechanism is reversed and descends, and is inserted into the greening shelf by the pushing mechanism. When a predetermined number of nursery boxes have been placed on one greening shelf, the full greening shelf is removed from the shelf, and then an empty greening shelf is loaded and set to the next shelf. Move to the point. At this time, it is not necessary to change the height of the greening shelf with a dedicated lifting device or the like, and it is only necessary to move the floor of the workplace as it is. In addition, as means for lowering the seedling box group received and held by the lift mechanism to the height of the greening shelf provided on the floor, the entire lift mechanism may be lowered using a dedicated driving device for each device frame. Although it is conceivable, according to this means, the entire lift mechanism becomes large and the equipment cost is high,
It becomes difficult to increase the speed of lifting and lowering the entire heavy lift mechanism, and the effect of reducing the processing time cannot be expected much. On the other hand, according to the configuration of the present invention, since the lift mechanism only extends a little downward and is configured to be capable of normal and reverse rotation, the remodeling can be performed easily and inexpensively, and the entire lift mechanism can be moved up and down. The lifting speed can also be made faster than in the case of

(Effects) Therefore, according to the second aspect of the present invention, it is possible to quickly and easily carry-in a set of empty greening shelves to a shelf location and carry out a full greening shelf. It is possible to improve the efficiency of shelf insertion work.
