○ Development of a seeding system
This study was conducted to develop a seeding system for producing high quality transplants. The seeding system consists of substrate filling apparatus, seeding apparatus, and nonrigid plastic pot supplying apparatus.
The test results showed that the supply accuracy of nonrigid plastic pot was fairly good when the loading pot had a inclination of 2 degrees, and nonrigid plastic pot with three suction pads produced better accuracy of 94~100%. Particularly, the suction pad with a diameter of 25mm showed 98% of high supplying capacity at 1 degree of inclination. In addition, the substrate filling rate was the highest 98% when the speed of conveyer was 5.0 cm/s.
The supply accuracy of nonrigid plastic pot was 100% when the air pressure was 3.5kg/cm2 and the filling accuracy of substrate was good 97.9% when the transport speed of pot was 2.8cm/s.
The seeding performance of seeding apparatus was the highest 99% in two-row vacuum drum type but it had a problem when the vacuum generator kept vacuum condition continuously. The vacuum nozzle seeder was quite effective in order to increase of seeding accuracy.
○ Development of a vegetable transplanting robot
This study was conducted to develop a vegetable transplanting robot consist with a seedling transplanting apparatus that transplanting seedling from seedling tray to transplant pot, a transplant pot transplanting apparatus that putting transplant pot on
cultivation bed, and a missing seedling removal apparatus that remove the missing seedling pot. The seedling transplanting apparatus consisted with the transplanting part, seedling tray moving part, transplant pot moving part, and control part. the
transplant pot transplanting apparatus composed of transplant pot tray moving part, transplant pot carrying part, transplant pot spacing part and transplant pot putting part.
The missing seedling removal apparatus consisted with a sensing part, a missing removal bar, and missing seedling pot gathering part. The day of transplanting of the head lettuce when the optimum starting time of using this robot was 21st after sowing for the result of seedling shape measurement and take-out examination. The optimum finger shape was slope pin type that thrust four
thin wire pins slopely. The transplanting capacity of the seedling transplanting apparatus, the transplant pot transplanting apparatus, and the missing seedling removal apparatus were 2800 pots/hour, 750 pots/hour, 600 pots/hour, respectively.
○ Development of an automatic vegetable seedling production system
This study was conducted to develop the automatic vegetable seedling production system for vertical plant factory which has the performance of better than 400 trays per a hour and 2% error to transfer the seedling tray along the line of the process of raising seedlings. The result of this study were summarized as follow;
1. Investigation of mechanism for loading and transferring the seedling tray
1) For the automation of the process of raising seedlings (sowing-germination-greening) among the working process of sowing - germination - greening - transplantation - cultivation - harvest in a plant factory, the automation line with enclosed-type rails are installed for interconnecting each process where seedling bed with wheel is transported on the rail was established.
2) It was developed the automatic carrying equipment that can load seedling trays
on loading position and transfer the seedling trays, which has completed the sowing process from a sower, onto seedling bed and that can transfer the seedling beds for transport of the trays.
3) The experiment of transferring the seedling tray by monorail pusher was carried out to figure out the required transfer force and problems during the pusher transport the plastic seedling trays, that has completed its sowing process, which are installed onto the board of different materials such as rubber board, wooden board, acrylic board and steel board. In addition, the seedling bed transfer test of an experimental device that allows for a push-transferrer via a pneumatic cylinder to transfer orderly the seedling bed with bearing roller on rail was carried out. Changes of transfer force was measured as well as the peak transfer force at transient state and transfer force at stead state, and bed sliding distances in order to obtain the optimum data for design the transferring device. From the result of these experiments, the automatic carrying equipment which can exactly load three of the seedling trays orderly on the loading position, transfer the all of three trays onto seedling bed and transfer the seeding bed on the rail was designed and made.
4) When three sowed trays on every board were transferred by pusher with the speed is at 30 cm/s, the maximum peak transfer force with maximum overshooting at initial transient state and the maximum transfer force at stead state were respectively 32.8 N, 29.4 N, on rubber board, 29.7 N, 22.5 N on a wooden board, 26.9 N, 19.6 N on a acrylic board, and 27.6 N, 19.1 N on an iron board.
5) Changes in the transfer force occurred its maximum at the moment when the pusher collided with the tray, after the collision gradually decrease until it become stable.
6) When all of two or three trays face wide edge to wide edge were transferred, it was occurred the overlapping of the tray's external bracket. It was required for a separation of each tray when transferred by push type transfer device.
7) When the seedling beds were transferred by push-transfer via a pneumatic cylinder, under the given free load speed of a pneumatic cylinder at 9, 13.5, 18.2 cm/s, the maximum peak transfer force and the maximum transfer force per a bed a bed were observed at 24.4 N, 44.2 N, 47 N and 7.3 N, 8 N, 9.7 N, respectively.
8) Under the given free load speed of a pneumatic cylinder at 9, 13.5, 18.2 cm/s, the average maximum peak transfer force and the average maximum transfer force per a bed were observed at 21.6 N, 33.2 N, 38.6 N and 7.2 N, 7.5 N, 8.4, respectively.
