 An embodiment of the present invention will be described below with reference to the drawings. The seedling raising facility is composed of a sowing section A, an unloading section B, and a germination chamber (not shown) arranged in the lateral vicinity of the unloading section B. As shown in FIG. 1, 0 is a box feeder that sequentially feeds out the stored empty nursery boxes 2, 1 is a conveyor for transporting the nursery boxes 2, 3 is a floor soil feeder that puts the soil into the nursery boxes 2, and 4 is Irrigation device for sowing seedling raising boxes supplied with bed soil, 5 sowing equipment for sowing seedling raising seedlings 2 after passing through the irrigation equipment 4, 6 for supplying soil to seeded seedling raising seedlings 2 Covered soil supply It is a device, and a seeding section A of a known technique is configured by these.

As shown in FIG. 2, reference numeral 7 is a lifting device that is lifted above the seeded nursery box 2 to which the soil cover has been supplied, and is located at the end of the transport conveyor 1. 8 is a lateral feed conveyor that laterally feeds the raised nursery boxes 2, 9 is a stacking device that drops the nursery boxes 2 that have been laterally fed by the lateral feed conveyor 8 and transfers them, and 11 is stacked in multiple stages. This is a carrying-out device for laterally transferring the nursery boxes to be loaded on the moving carriage 12, and the carrying-out section B is constituted by them.

In this seedling raising facility, the seeded seedling raising boxes 2 created in the seeding section A are stacked in 30 stages at the carry-out section B, and the lid member 2 is manually operated on the uppermost stage seedling raising boxes 2 of the stacked seedling raising boxes. It is configured to be mounted on a moving carriage 12 for transferring to the germination chamber after covering H with a total of 31 stages of nursery box groups G. Next, the detailed structure around the carry-out section B will be described.

As shown in FIGS. 2 to 5, the lifting device 7 is composed of vertically-rotating chains 7 a, 7 a arranged on the left and right of the conveyor 1 and attached to the chain 7 a at appropriate intervals. This is a structure in which the seedling raising box 2 is placed on the placing claws 7b, 7b and is then transported. The front and rear chains 7a, 7a are provided with a relative difference such that the rear mounting claw 7b is slightly higher than the front mounting claw 7b, and when the chains 7a, 7a are lifted from the conveyor 1. Therefore, the seedling raising box 2 is set in a tilted posture in which the lower side in the carrying direction is high.

The lateral feed conveyor 8 is constructed by fixing a plurality of sets of push-out arms 8b set to a width narrower than a belt width to a belt 8a which is wound around front and rear wheels 13 and 14 and driven to rotate. It is configured. Between the starting end portion of the lateral feed conveyor 8, specifically, the intermediate wheel body 15 arranged between the lifting device 7 and the laminating device 9 and the front wheel body 13, the tilted posture for lifting is provided. A belt 8a is tilted rearward and upward in accordance with the nursery box 2, and a transport path W is formed so that the nursery box 2 itself is transported in an obliquely inclined posture to the upper rear side.

That is, the intermediate wheel 15 supports the upper moving portion 8u of the belt 8a, and the lower moving portion 8s is slidably supported by the pair of left and right guide members 26, 26 as shown in FIGS. The guide member 26 and the subsequent parts are configured to be horizontally movable. It is convenient to provide a sliding contact guide plate 27 below the guide member 26 so that the rearward movement of the nursery box 2 can be smoothly changed to horizontal movement.

The laminating apparatus 9 includes a holding mechanism 16 for receiving and temporarily holding the nursery box 2 laterally fed by the lateral conveyor 8 and a laminating unit fixed to a pair of left and right vertically rotating descending chains 17a, 17a. A stacking mechanism 17 for stacking the seedling raising box 2 on the claws 17b, 17b. The holding mechanism 16 is composed of a pair of left and right openers 16a and 16a that can be freely opened and closed around the front-rear axis P, and these openers 16a and 16a are used for raising seedlings as shown in FIG. The seedling-raising box 2 is dropped and transferred to the stacking mechanism 17 by changing from the box-holding posture to the outward-opening posture. Below the openers 16a, 16a, a counter 22 including a light emitter 22a and a light receiver 22b is provided so that the number of seedling raising boxes that are dropped and supplied can be measured. The stacking mechanism 17 is configured to move down by one stage of the box when the seedling raising box 2 is supplied from the holding mechanism 16.

The carry-out device 11 includes a vertical feed mechanism 10A for slightly transferring the 30-stage seedling raising boxes 2 stacked by the stacking device 9 along the transport direction of the transport conveyor 1, and a transport conveyor for reloading the transport cart 12. 1 and a lateral feed mechanism 10 B that laterally feeds in a direction orthogonal to the transport direction. That is, a total of 31 stages of seedling raising box groups G, each of which has a lid raising seedling raising box 2H at the uppermost stage, are vertically and horizontally transferred by the unloading device 11, and beside the unloading device 11, a moving carriage 12 for transferring to the germination chamber C. Are placed side by side.

As shown in FIG. 6 and FIG. 7, the moving carriage 12 is for loading a group of seedling raising groups G in two rows each in vertical and horizontal directions, for a total of four groups. It is composed of a mounting table 20 on which two rows of storage sections 19, 19 are formed and four rolling wheels 21. An unobtrusive loading / unloading section 23 is formed on both sides of the storage section 19, and the nursery box group G is slid and moved horizontally from the loading / unloading apparatus 11 to move from the loading / unloading section 23 to the storage section 19. It can be carried in and out.

Further, a vertical frame 24 that straddles the upper portions of the horizontal partitions 18 at three locations is provided at the left and right center of the mounting table 20. Four substantially L-shaped guard members 25 capable of preventing the falling are provided so as to be rotatable around a vertically-rotating fulcrum Z 1. These guard members 25 are pivotally moved so that the guard member 25 extends laterally so as to be positioned in the inlet / outlet portion 23 (the state shown on the left side of FIG. 7) and retracts inward to open the inlet / outlet portion 23. The posture can be freely changed to the retracted posture (the state shown on the right side in FIG. 7). It is convenient to provide a detent mechanism (not shown) capable of retaining and maintaining the guard member 25 at the above-mentioned two positions, and to provide a spring (not shown) for urging the guard member 25 toward the drop-off restraining posture.

In other words, when the nursery box group G is placed on the moving carriage 12 from the carry-out device 11 and when the nursery box group G is taken out of the moving carriage 12 in the germination chamber, the guard member 25 is in the retracted posture and the loading / unloading section 23. The guard member 25 is kept in the fall-off restricting posture during movement, and it is possible to effectively prevent the seedling raising box 2 from falling out of the trolley from the loading / unloading section 23 due to vibration or shock during transportation.

As shown in FIGS. 3, 7, and 8, the moving carriage 12 is sequentially carried to a predetermined position beside the carry-out device 11 by the carriage carrying device D provided along the carrying conveyor 1. I am doing it. The trolley carrier device D is composed of a pair of left and right rails 28, 28 and a drive mechanism 29 laid between them such as a chain or a belt. On the other hand, a protrusion 12t that engages with the drive mechanism 29 is attached to the bottom surface of the movable carriage 12, and if the movable carriage 12 is manually pushed to engage the protrusion 12t with the starting end portion of the drive chain mechanism 29, the movable carriage 12 will be movable. The carrier device D is ready for carrying.

Then, as shown in FIG. 3, an automatic stop device E for stopping the movable carriage 12 at a predetermined position beside the carry-out device 11 is provided. That is, the detection switch 30 that operates by contact with the pipe 12p mounted on the side surface of the moving carriage 12, the stopper 31 that can stop the moving carriage 12 by acting from the side of the moving path of the carriage, and the stopper 31 An automatic stop device E is configured by connecting a reciprocating mechanism 32 for moving in and out, a timer 33, a motor 34 of a drive mechanism 29, and a start switch 35 to a controller 36.

In other words, when the detection switch 30 detects and operates by contact with the moving carriage 12, the push-out mechanism 32 is driven to cause the stopper 31 to project and move, and the predetermined time set in the timer 33 elapses. After that, the motor 34 is stopped, and the moving carriage 12 is stopped at a position where the mounting base 20 and the stopper 31 come into contact with each other, and the driving system of the drive mechanism 29 has a torque that allows idle driving when the stopper 31 acts. It is equipped with a limiter TL. Then, when the starting switch 35 is operated when the seedling raising box 2 is mounted, the controller 36 functions so that the stopper 31 moves back and forth and the motor 34 is started.

Further, as shown in FIG. 3, the carry-out section B is provided with a counter sensor 37 for detecting the presence or absence of the moving carriage 12 that is about to exit from the carry-out section B, and a number display device 38 for displaying the detection information. It is possible to visually check how many fully loaded mobile vehicles 12 have passed.

[Other Embodiments] In the bogie structure of the present embodiment, in order to avoid the interference between the rotational movement locus K of the guard member 25 and the nursery box 2, the nursery box group G and the guard member 25 in the drop-off restraining posture. There was a certain distance. On the other hand, as shown in FIG. 9, when the rotation fulcrums Z are arranged laterally offset, the rotation movement locus K is partially outside the full width of the moving carriage 12, but in the falling-off restricting posture. The nursery box group G and the guard member 25 can be brought closer to each other, which is convenient because the lateral width and the longitudinal length of the storage section 19 can be reduced. With this means, it is convenient if the guard member 25 is maintained in the falling-off restricting posture by a locking means such as a slightly tight detent mechanism.

It should be noted that reference numerals are added to the claims of the utility model for convenience of comparison with the drawings, but the present invention is not limited to the configurations of the accompanying drawings by the entry.
