Further, the front edges of the guides 48a, 48b are also bent so as to spread outward as they reach the front to form a guide part.
can be easily attached to the frames 37, 37.

In addition, since the upper guide 48b rotates and falls while the rear end of the storage box 3 is pinched, the storage box 3 is accurately dropped.

(effect) Next, we will discuss the effect.

In a predetermined work area, the pot sheet paper 1 is placed and fitted onto the storage box 3, and the storage box 3 is stacked and supplied to the storage box automatic feeding device 10 at the starting end of the transfer table 7. Then, only the storage boxes 3 at the lowest stage are sent out one after another without any gaps, and when the pot sheet paper 1 passes under the soil covering supply device 13, it receives the supply of covering soil, and when it passes under the seed rice supply device 17, it receives the seed rice. When passing under the bed soil supply device 19, the bed soil is supplied, and the bed soil compaction roller 2
When passing under 2, the bed soil is compacted.

Then, a seedling raising box is placed from above on the pot sheet paper 1 that has been supplied with bed soil, and the reversing device is used to invert the seedling raising box so that the seedling raising box is at the bottom and the storage box 3 is at the top. send. When the flange 5 of the storage box 3 sent to the storage box take-out device 27 moves onto the rail 28, the motor 33 is actuated by the sensor to rotate the rotating arm 31 to point A. Then, the rails 28 are also inclined, forming a sloped surface, so that the storage box 3 flows under its own weight and falls onto the conveyor 34. Add soil between each pot 2 of the pot sheet paper 1 in the remaining seedling growing box.

The storage box 3 is located at the terminal end 35 of the conveyor 34.
(the starting end of the transfer table 7). In the conventional case, since there is no device after the end of the conveyor 34, the leading end of the storage box 3 falls onto the floor, and the rear end of the storage box 3 does not reach the end of the conveyor 34 at any time. In some cases, even the storage box 3 remained behind and obstructed the movement of the next storage box 3. Therefore, a worker was always there, picking up the boxes one after another and transporting them to the work site. However, in the present invention, the storage boxes 3 transported by the transport conveyor 34 are placed at the terminal end 35 of the transport conveyor 34. When you reach the standing wall 4 of the storage box 3
The engaging piece 44 engages with the housing box 3 to move the storage box 3 upward.

Thus, the lower end of a support arm 45 that projects upward is fixed to a substantially central position of the frame 37 in the transport direction, and the base of a mounting arm 46 is rotatably pivoted to the upper end of the support arm 45. The base of a presser device 47 is fixed to the tip of the mounting arm 46, and the presser device 47 is formed of a thick metal plate, and its horizontal width is wider than the inner spacing of the frame 37. The tip is positioned so that it is pressed by its own weight from above so that the center of gravity of the storage box 3 rises to a position beyond the upper end, so that the center of gravity of the storage box 3 passes through the passive sprocket 42 and falls reliably. The rear end of the storage box 3 is pressed from above until the rear end of the storage box 3 reaches this position to prevent the rear end of the storage box 3 from lifting up. Therefore, when the storage box 3 reliably engages with the engagement piece 44 and rises and passes below the tip of the holding device 47,
Fall immediately.

In this case, the frame 37 of the lifting device 36,
37 are formed at substantially the same distance as the left and right width of the storage box 3, but when the transport conveyor 34 is transferred to the lifting device 36, the engagement piece 44 of the lifting device 36 is connected to the front end of the storage box 3. Since it engages with the upright wall 4 and is pulled upward, the rear end of the storage box 3 may swing left and right and climb onto the frames 37 and come off, and may also be pulled away from the storage box lifting device 36. Even when the storage box 3 falls, the rear end may swing left and right and may not fall to a predetermined position.

However, in the present invention, upper and lower guides 48a and 48b are provided at the upper and lower parts of the storage box lifting device 36, and each of the upper and lower guides 48a and 48b is formed by a pair of left and right substantially vertical upright plates. , 37 are arranged side by side at intervals substantially equal to the horizontal width of the storage box 3, and are formed to have a height such that the side edges of the storage box 3 come into sliding contact with each other. The rear edge is bent so as to spread outward as it reaches the rear, and forms the guiding part 5.
6, 56, the conveyor 3
4, when the storage box 3 reaches the lifting device 36, the engagement piece 44 of the lifting device 36 engages with the upright wall 4 of the storage box 3 and is pulled upward, so that the front end of the storage box 3 is pulled upward by the lower guide guide 48a. The storage box 3 is brought into contact with the guiding parts 56, 56 on the rear edge and guided to an appropriate position approximately in the center of the frames 37, 37, and then pulled upward with the side edges of the storage box 3 slidingly contacting the lower guide 48a. be done.

When the storage box 3 reaches the top of the lifting device 36, the front end of the storage box again contacts the upper guide 48.
The storage box 3 comes into contact with the guide portions 56, 56 of the lower guide 48b and is guided to the appropriate position. Since the side edges of the storage box 3 slide against the lower guide 48b as it falls, the rear end of the storage box 3 falls without swinging left and right. Therefore, the storage box 3 can be dropped in the specified position.

(Effect) The above-mentioned known thing has the following features:
A conveyor is provided to return the storage boxes taken out by the storage box take-out device to the starting end of the transfer table, but since the lifting device of the present application is not provided, the storage boxes taken out by the storage box take-out device are not returned by the conveyor. There was a problem in that the storage box that was dropped would simply fall onto the floor at the tip, and the next storage box would collide with it and become stagnant.

However, in the present invention, the soil covering supply device 13, the seed rice supply device 17, the bed soil supply device 19, and the seedling raising device are placed above the transfer table 7 that transfers the top-open storage box 3 into which the pot sheet paper 1 can be fitted from above. A reversing device capable of reversing the entire storage box 3 after fitting the box from above and a storage box take-out device 27 for taking out the storage box 3 after reversing are provided, and at a position below the transfer table 7, the storage box 3 is provided.

A storage box lifting device 36 having a chain 43 wound thereon is provided, and the lifting device 36 is formed to be inclined so as to become higher toward the rear.
A pair of substantially vertical left and right lower guide guides 48a are provided at the lower part of the upper surface of the storage box 3, with which the side edges of the storage box 3 at the beginning of the upward sliding contact are provided, and at the upper part of the upper surface of the lifting device 36, a front and rear intermediate position is provided. It was returned because it is a storage box lifting device for a pot sheet seeding device, which is provided with a pair of substantially vertical left and right upper guides 48b on which both rear side edges of the storage box 3 that rotates on a fulcrum and falls down come into sliding contact. Since the storage box 3 is lifted by the lifting device 36 and then falls, the subsequent storage box 3
will not rear-end.

At the bottom of the lifting device 36, there is a pair of substantially vertical left and right lower guide guides 4 on which the side edges of the storage box 3 slide.
