Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention sequentially provides a seedling raising box on a seeding plant conveyor.
The present invention relates to a seedling raising box automatic supply / supply device configured to send boxes one by one.

<Prior Art> In a conventional automatic nursery box feeder / supplier, a stacked nursery box was manually placed on a supply conveyor. In addition, there are some automated ones, but it was a large-scale one that required the second floor.

<Problems to be Solved by the Invention> Four corner posts are provided on the supply conveyor to hold the stacked seedling raising boxes, and these corner posts are an obstacle to manual loading of the stacked seedling raising boxes. It was hard. It was also impossible to store and store a large amount.

This invention makes it possible to store and store seedling raising boxes, and also to automatically feed the seedling raising boxes one by one.

<Means for Solving the Problems> The seedling raising box automatic feeding / supplementing apparatus according to the present invention is a delivery stacking seedling raising seedling that is placed on a feeding conveyor and surrounded by four corner posts 13, 14, 15, 16. A supply conveyor is arranged on the rear side of the supply device configured to sequentially feed the boxes B one by one from the bottom, and rear opening guide pieces 19, 20 are provided on the front corner posts 13, 14 and the rear corner posts 15, 16 are provided.
The upper open guide pieces 25 and 26 are provided in the above, the supply conveyor 5 is arranged at a position higher than the supply conveyor 6 by the height of several seedling raising boxes, and the sensor 23 is attached to the front corner posts 13 and 14. The sensor 23 is turned on when the remaining number of the delivery piles for raising seedlings B is less than a certain number less than the number of seedling raising boxes, and when the sensor 23 is turned on, the supply conveyor 5 is rotated and manually at a time. It is configured such that the supplemental stacking seedling raising box A placed in the stacking state moves onto the sending stacking seedling raising box B.

<Operation> When the delivery stacking seedling raising box B on the supply conveyor 6 is reduced to a certain number or less, the supply conveyor 5 operates to automatically supplement the supplementing stacking seedling growing box A.

<Example> A description will be given with reference to the drawings.

1 is a seedling raising box, 2 is the upper edge of the seedling raising box, 3 is a leg piece projecting downwardly from the four corners of the lower surface of the seedling raising box. To prevent lateral displacement.

Reference numerals 5, 6, and 7 are a supply conveyor, a supply conveyor, and a seeding plant conveyor, which are sequentially arranged. Here, the replenishment conveyor side is the rear 9, the seeding plant conveyor side is the front 8, and the left and right sides when viewed from the back to the front are left 10 and right 11, respectively.
And

The replenishment conveyor 5 is adapted to be intermittently driven by an electric motor 12, and a predetermined number (for example, 15) of replenishment and stacking nursery boxes stacked on the replenishment conveyor are kept at an interval E that is accessible. It is designed to be placed sequentially from front to back.

The supply conveyor 6 is disposed below the front of the supply conveyor 5, and the front corner posts 13 and 14 of L-shaped cross section are slightly tilted to the front left and right of the supply conveyor 6 so as to sandwich the front corner of the nursery box. The height C of the front corner posts 13 and 14 is higher than the maximum height of the stacking nursery box. Front corner post with L-shaped section 1
Rear opening guide pieces 19, 20 that open rearward are provided on both side walls of 3, 14 above a predetermined height D for at least several stacked nursery boxes. The lower ends of the front walls of the left and right front corner columns 13 and 14 are cut out by a height F enough to pass one seedling raising box to form a delivery port 21. Further, a sensor 23 is attached to a horizontal plate 22 which is horizontally mounted between the left and right front corner posts 13 and 14, and the sensor 23
Is provided at a position corresponding to the height D of several of the above-mentioned stacked seedling raising boxes.

Rear corner posts 15 and 16 having an L-shaped cross section are vertically installed vertically on both sides of the rear part of the supply conveyor 6 so as to sandwich the rear corner part of the delivery stacking nursery box, and the height of the rear corner posts 15 and 16 is replenished. It is lower than the conveyor 5.

On the side walls of the rear corner posts 15 and 16, wide upper open guide pieces 25 and 26 that are opened upward and rearward are formed, and the upper ends of the upper open guide pieces 25 and 26 reach a position higher than the supply conveyor. .

The supply conveyor 6 is provided with hook pieces 27 at appropriate intervals, and the hook pieces 27 hit the lowermost stage seedling raising box 1 of the delivery stacking seedling raising box and push it forward, and push out through the delivery port 21. ing.

The seedling raising box 1 on the sowing plant conveyor 7 is provided with soil filling, soil irrigation, sowing, and soil covering.

A control box 33 is connected to the electric motor 12 for the supply conveyor and the sensor 23. A delivery stacking nursery box B, which reaches a position higher than the sensor 23, is placed on the supply conveyor 6, and a predetermined number of stacking supplementary seedling growing boxes A are placed on the front part of the supply conveyor 5.

When the supply conveyor 6 is driven, the hook pieces 27 push the seedling raising box 1 at the lowermost stage, pass through the outlet 21 and place it on the seeding plant conveyor 7. By repeating this operation, the sending-up and stacking nursery boxes are removed one by one from the bottom.

The sowing plant conveyor 7 has a feed speed that varies depending on the type of seeds, and moves at a slower speed than the supply conveyor 6. Therefore, the supply conveyor 6
Keeping an extra space between the hook pieces 27, 27 of one, an appropriate time interval between sending one seedling raising box 1 by one hook piece 27 and sending the next seedling raising box 1 by the next hook piece 27 Is trying to keep. Therefore, there is a time period during which the delivery stacking nursery box B does not move.

The sensor 23 captures when the number of delivered pile-up nursery boxes B has decreased to a predetermined number. The signal of the sensor 23 is transmitted to the electric motor 12 for the replenishment conveyor via the control box 33,
The supplementary stacking nursery box A on the supplementary conveyor 5 is moved forward.

The replenishment and stacking nursery box A moves forward between the left and right upper opening guide pieces 25, 26. At this time, the wide upper opening guide pieces 25, 26
Since it passes through the space while falling down,
The left and right positions are adjusted, and the front leg pieces 3,3 on the lower surface of the supplementary stacking seedling raising box A move forward while being fitted into the inner wall surfaces 4,4 of the lower sending stacking seedling raising box B. Then, when the supplementary stacking nursery box A hits the front corner posts 13 and 14 through the rear opening guide pieces 19 and 20,
The sensor 23 is turned off, the supply conveyor 5 is stopped, and the lower rear part of the supply stacking nursery box A fits into the rear corner posts 15 and 16. The above operation is repeated to feed in the replenishment status nursery boxes one after another.

The shape of the sensor 23 is not limited to that of the illustrated embodiment.

<Effects of the Invention> According to the present invention, the stacking seedling raising boxes A placed on the replenishing conveyor 5 in a piled state at a time by hand can be efficiently and reliably sent to the seeding plant conveyor 7 one by one. . Further, the entire apparatus can be downsized as compared with the conventional automated one.
