BACKGROUND OF THE INVENTION
The present invention relates to a plant cultivation facility and a plant cultivation method for cultivating a plant while moving the plant from a cultivation room in which treatment conditions are determined to a cultivation room under other treatment conditions. In addition, a plant here is a general term for things other than animals in organisms, and includes algae and bacteria in addition to mushrooms, vegetables, and flowering plants.
[0002]
[Prior art]
In general, when cultivating plants such as mushrooms, vegetables, or flower buds, the plants are often cultivated while being moved from a cultivation room where treatment conditions are determined to a cultivation room under other treatment conditions. For example, when cultivating mushrooms, inoculate the sawdust packed in the cultivation container with the inoculum, cultivate the inoculated cultivation container in the culture room, generate fruit bodies in this container in the budding room, and level it. After leveling in the room, the size of the fruiting body is adjusted in the suppression room, and after the work such as paper winding, it is grown and harvested in the growth room. At this time, in the cultivation rooms such as the sprouting room and the leveling room described above, processing conditions suitable for cultivation such as temperature / humidity and carbon dioxide concentration are determined, and the environment is maintained. And conventionally, in such a plant cultivation facility, a plant is automatically carried in and out of the cultivation room by providing a conveying device in each cultivation room.
[0003]
[Problems to be solved by the invention]
By the way, in the conventional plant cultivation equipment, the plant is automatically carried in and out of the cultivation room, but the workers are transferring the plants between the cultivation rooms. There was a problem that the labor required for the work was large. Also, because the degree of growth of the plant is judged by the worker entering the cultivation room and actually touching it visually or by hand, or by the worker managing the occupancy time of the plant, As the number of plants to be cultivated increases, there is a problem that the burden on work increases.
[0004]
Therefore, the mushroom cultivation facility introduced in Japanese Patent Application Laid-Open No. 4-121115 includes a plurality of cultivation rooms each maintaining a specific environment, and automatically controls the occupancy time management and transfer of the mushroom cultivation container. Configuration is considered. However, in this configuration, since the degree of plant growth is managed by the plant occupancy time, if there are individual differences in plant growth due to slight environmental differences in the cultivation room, the actual plant The plant is transferred to the next cultivation room in a state that does not necessarily coincide with the growth. That is, for example, a plant that is not actually growing enough may be transferred to the next cultivation room, or on the contrary, a plant that is growing sufficiently may be grown excessively without being transferred. There is a problem that the quality of the harvested plants tends to vary. Moreover, since it is managing centrally according to the occupancy time, there is a problem that it is difficult to cultivate plants of a plurality of varieties having different growth degrees in the same cultivation room.
[0005]
The present invention has been made in view of such problems, and is intended to make the quality of the plant to be cultivated uniform, and plant cultivation equipment and plant cultivation capable of easily cultivating different varieties of plants in the same cultivation room. It aims to provide a method.

[0016]
As shown in FIG. 1, a three-dimensional shelf 11 having a plurality of shelves 10 is installed in the cultivation rooms 1, 2, 3, and a pallet 12 is placed on each shelf 10. The pallet 12 is equipped with a plurality of containers 14 for holding a plurality of cultivation containers 13 in which the fruit bodies that have been inoculated with the inoculum have been generated.
[0017]
As shown in FIG. 2, each of the cultivation rooms 1, 2, 3 is a crane (conveyance) that is movably disposed on the above-described three-dimensional shelf 11 and a rail 15 that is laid in a region sandwiched between the three-dimensional shelf 11. Apparatus) 16, a storage conveyor 17 for storing the pallet 12 into the cultivation rooms 1, 2 and 3, and a storage conveyor 18 for discharging the pallet 12 to the outside. Moreover, each cultivation room 1,2,3 is equipped with the air-conditioner which is not shown in figure for making environment, such as indoor temperature and humidity, a carbon dioxide density | concentration, into a predetermined value.
[0018]
Returning to FIG. 1, the three-dimensional shelf 11 is composed of multi-stages such as four or five stages, and is mainly composed of shape steel. And each pallet 12 is placed on each shelf 10 provided in a partitioned manner. The crane 16 includes a lift stage 19 that is moved up and down with the pallet 12 mounted thereon, and the pallet 12 is reciprocated in the direction of the shelf 10 on a rail 20 provided on the lift stage 19.
[0019]
The crane 16 receives the pallet 12 from another cultivation room by the warehousing conveyor 17 and then moves the pallet 12 to the shelf 10 for mounting, or moves the pallet 12 taken out from the shelf 10 to another cultivation room. The lift stage 19 is moved up and down at the same time while reciprocating on the rail 15. The crane 16 also includes image detection means (detection means) 21 for detecting the degree of growth of mushrooms growing in the cultivation container 13 on the pallet 12 taken out on the lift stage 19.
[0020]
The image detection means 21 is installed on the side plate 22 of the lift stage 19 with a device for detecting an image such as a CCD camera provided in the housing. The image detecting means 21 can detect the image of the mushroom on the lift stage 19 from one side direction, and the installation location is determined so that the image detecting means 21 can simultaneously detect the image of the cultivation container 13 in the front row. It has been. In addition, the image detection means 21 transmits the detected image wirelessly to a control device (determination means) 23 that is installed apart from the image detection means 21. Furthermore, the zoom and focus associated with image detection are arbitrarily set by being controlled by the control device 23.
[0021]
The transfer conveyor 4 receives the pallet 12 delivered from the delivery conveyor 18 of each of the cultivation rooms 1, 2, 3, moves to the other cultivation rooms 1, 2, 3 and delivers the pallet 12 to the entry conveyor 17, It is comprised so that reciprocation is possible between each cultivation room 1,2,3. Moreover, the conveyor 5 is a transfer conveyor so that the pallet 12 on which the cultivation container 13 is placed can be carried into each of the cultivation rooms 1, 2, 3 and carried into and out of a cigarette station (not shown). 4 are arranged side by side.
[0022]
The control room 6 is provided in a place different from the cultivation rooms 1, 2, and 3, and the control device 23 and the monitor 24 described above are installed in the room. The control device 23 is configured to control and control each of the air conditioners of the cultivation rooms 1, 2, 3, the crane 16, the warehousing conveyor 17, and the warehousing conveyor 18. Further, the control device 23 controls the image detection means 21 and displays the detected mushroom image on the monitor 24 based on the image transmitted from the image detection means 21. Moreover, the control apparatus 23 judges whether to move a mushroom to another cultivation room based on the image detected by the image detection means 21.
[0023]
Next, operation | movement of the plant cultivation equipment of this embodiment is demonstrated with reference to the flowchart of FIG. FIG. 3 shows a sequence centered on the movement of the pallet 12 on the control device 23 including the monitor 24 in the above-described embodiment. Each cultivation room 1, 2, and 3 is controlled by the substantially same independent sequence regarding the movement of the pallet 12, and here, operation | movement in the cultivation room 2 (suppression room) is mainly demonstrated.
[0024]
In order to start the operation, an instruction for automatic conveyance operation of the plant cultivation facility is performed.
Each cultivation room 1, 2, and 3 is set with temperature, humidity, carbon dioxide concentration, and the like by an air conditioner, and each environment is maintained. Furthermore, each pallet 12 is given an identification code in advance, and the control device 23 stores which shelf 10 in the cultivation rooms 1, 2, 3 is mounted with each identification code (pallet 12). . Further, the initial value of the detection period corresponding to each identification code is input in advance by the worker, and this is stored in the control device 23. The detection period is a period in which the detection operation is performed by the image detection unit 21 after the count is started, and is set so that mushrooms do not grow excessively within the detection period. ing.
[0025]
First, the control device 23 confirms whether or not there is an instruction for entering the pallet 12 from the transfer conveyor 4 to the cultivation room 1 (step 100).
If there is no entry command in step 100, the control device 23 checks whether there is a pallet 12 that has passed a predetermined detection period in the cultivation room 2 (step 101). If there is no pallet 12 that has passed the detection period, the process returns to step 100. If the pallet 12 is found, the crane is moved to move the lift stage 19 to the shelf 10 on which the pallet 12 is mounted. 16 is instructed (step 102). At this time, when there are a plurality of pallets 12 that have passed the detection period, first, any pallet 12 that has not yet been detected by the image detection means 21 in the cultivation room 2, and then the immediately preceding detection. The movement to the pallet 12 that appears first is instructed in the order of the pallet 12 with the oldest date and time.
[0026]
When the lift stage 19 moves to the designated pallet 12, the pallet 12 is taken out from the shelf 10 onto the lift stage 19 (step 103). Then, the degree of growth of the mushroom is detected by an image by the image detection means 21, the detected image data is transmitted to the control device 23 wirelessly, and the image is displayed on the monitor 24 in the control room 6 (step 104: detection step). ).
[0027]
Subsequently, it is checked whether or not the mushroom can be normally recognized from the transmitted image data (step 105). If the image recognition cannot be normally performed, an error is displayed through the monitor 24 and waiting for the operator to operate (step). 106). When the image recognition can be normally performed, the control device 23 determines whether or not to move the mushroom to the next cultivation room 3 (step 107: determination step).
[0028]
The determination of the control device 23 in step 107 is performed as follows, for example. First, mushrooms that can be seen from one side direction and the cultivation container 13 that appears in the front row are recognized separately from the image data in which the image detection means 21 has detected mushrooms. Subsequently, the area area of the mushroom corrected by the focal length and the distance (center of gravity distance) from the center of gravity of this area to the upper end surface of the cultivation container 13 are calculated, and the two calculated data are determined in advance as a reference. Check if the value is within the specified range. And when it is in the predetermined range, the mushroom is moved to the next cultivation room, and if not, it is determined that it is not moved.
[0029]
If it is determined in step 107 that the detected mushroom (pallet 12) is not moved to the next cultivation room 3, the difference between the area area and the center of gravity distance described above and the reference value is obtained, and based on this difference, the current detection is performed. A new detection period until the next mushroom is detected is calculated, and the identification code of the pallet 12 is associated with this detection period and stored (step 108). That is, here, when the difference from the reference value is large, the detection period is calculated to be relatively long, and conversely when the difference is small, the detection period is calculated to be relatively short. It approaches the standard size. Then, the pallet 12 is returned to the original shelf 10 (step 109), and the process returns to step 100.
[0030]
On the other hand, if it is determined in step 107 that the mushroom (pallet 12) is moved to the next cultivation room 3, the crane 16 is instructed to move the pallet 12 on the lift stage 19 to the delivery conveyor 18, and the pallet 12 is moved. It is delivered to the delivery conveyor 18 (step 110: conveyance step). And after the pallet 12 is delivered to the delivery conveyor 18, the transfer conveyor 4 is instructed to receive the pallet 12, and when the transfer conveyor 4 moves and receives the pallet 12, the pallet 12 is transferred to the next cultivation room 3. A warehousing command is issued (step 111), and the series of operations is terminated.
[0031]
If there is a pallet 12 entry instruction from the transfer conveyor 4 to the cultivation room 2 in step 100, that is, a pallet 12 entry instruction from the cultivation room 1, the transfer conveyor 4 is first activated and delivered to the entry conveyor 17. The pallet 12 is stored in the room (step 112). Then, the pallet 12 on the warehousing conveyor 17 is transferred to the lift stage 19, moves as it is to the empty shelf 10 of the three-dimensional shelf 11 (step 113), and is mounted on the shelf 10 (step 114). And the control apparatus 23 matches and memorize | stores the mounted shelf 10 and the identification code of the pallet 12 (step 114). Furthermore, the initial value of the detection period in the cultivation room 2 corresponding to the identification code of the pallet 12 mounted on the shelf 10 is read, time counting is started (step 115), and the series of operations is terminated.
[0032]
And similarly in the cultivation rooms 1 and 3, it is moving in the substantially same sequence as the cultivation room 2 mentioned above. Therefore, the plant cultivation equipment of the present embodiment cultivates mushrooms by sequentially moving the pallet 12 with mushrooms from the cultivation room 1 to the cultivation room 2 and then to the cultivation room 3 by such a series of operations. It has become.
[0033]
The present embodiment includes an image detection means 21 for detecting the growth degree of the mushroom, detects the actual growth degree of the image detection means 21, and the next cultivation of the mushrooms according to the detected growth degree of the mushroom. We move to room. Therefore, even if individual differences occur in the growth of mushrooms due to slight differences in the environment in each cultivation room 1, 2, 3, etc., the actual growth degree of mushrooms is detected, and only mushrooms with a predetermined growth degree are By moving to a cultivation room, it becomes possible to make the degree of growth of the moving mushrooms to a certain degree, and the variation in the quality of the mushrooms at the time of harvest can be kept small. Moreover, when cultivating mushrooms of a plurality of varieties having different growth degrees, the image detection means 21 detects the actual growth degree of the mushrooms of each varieties, thereby making it easy to manage the growth of each cultivar. Different types of mushrooms can be easily cultivated in the same cultivation room.
[0034]
Moreover, since the growth of the mushroom is detected by the image by the image detection means 21, the actual growth of the mushroom can be detected more accurately, and the cultivation according to the actual growth degree of the mushroom can be more reliably performed. Furthermore, since the image detection means 21 is installed in the crane 16 that moves the mushrooms, and the image detection means 21 moves to the vicinity of the mushroom installation location in the cultivation room by moving the crane 16, a small number of image detections are made. By means 21, all the mushrooms in the cultivation room can be detected.
[0035]
Moreover, since the control apparatus 23 determines whether this embodiment moves a mushroom to another cultivation room based on the result detected by the image detection means 21, determination of a detection result continuously in a short time. In addition, it is not necessary for the worker to judge the detection result, and the labor of the worker can be reduced. And since the control apparatus 23 is installed in the control room 6 separated from the cultivation rooms 1, 2, 3, it is less likely that an operator will enter into the cultivation rooms 1, 2, 3, and a plurality of cultivation rooms Since 1, 2 and 3 can be managed in the same place, work efficiency is improved.
[0036]
In addition, a detection period is set for each pallet 12 in advance, and the degree of growth of mushrooms is detected after the detection period has elapsed. By mounting separately, it becomes possible to detect at an appropriate time according to the degree of growth of mushrooms of each variety, and it is possible to efficiently cultivate mushrooms of a plurality of varieties. Furthermore, if it is determined in step 107 that the mushroom is not moved to the next processing step, a new detection period is set according to the mushroom growth degree so that the size of the mushroom at the time of the next detection approaches the reference size. Therefore, useless detection operation can be omitted.
[0037]
In the present embodiment, the plant to be cultivated is taken care of, but the present invention can be applied to other plants as long as a plurality of cultivation rooms each having a predetermined processing condition are required. Further, the next processing step to be moved based on the result detected by the image detection means 21 is not limited to a room such as a cultivation room, but may be another processing step in the same facility such as a cigarette station. In addition, the operator may determine whether to move the detected mushrooms to the next cultivation room from the image displayed on the monitor 24.
[0038]
Moreover, in this embodiment, the crane 16 which is a conveying apparatus of the pallet 12 and each conveyor are arrange | positioned in the cultivation chambers 1, 2, and 3, and it carries out automatically, but it is a large-scale conveying apparatus. In a small cultivation facility that does not require a plant, an operator moves a plant from a cultivation room to another cultivation room. Even in this case, for example, by providing a monitor 24 outside the cultivation room and monitoring the result of detecting the degree of plant growth from the monitor 24, the number of times the worker enters the room for confirmation is reduced. It is possible to increase the work efficiency.
[0039]
Furthermore, in the present embodiment, the pallet 12 is taken out from the shelf 10 and this detection on the lift stage 19 of the crane 16 is performed. However, the mushroom can be detected without being taken out from the shelf 10. Do. In this case, for example, instead of installing the image detection means 21 toward the lift stage 19, the image detection means 21 is installed on the crane 16 toward the shelf 10, and the mushrooms are still installed on the shelf 10. Is detected. Thereby, the time required for taking out the pallet 12 to the lift stage 19 can be reduced, and the detection operation can be performed more efficiently. In addition, it is possible to further reduce the time required for the detection operation by installing the image detection means 21 for each shelf 10 and sequentially detecting the image detection means 21 in order.
[0040]
In this embodiment, the degree of growth of the mushroom is determined for each pallet 12. However, when the individual difference in the degree of growth is small, by detecting one pallet 12, another pallet 12 that is close to the warehousing time. It is also possible to omit the detection of. Thereby, the time required for detection can be reduced and the control can be simplified.
[0041]
The means for detecting mushrooms is a detection sensor for detecting the growth of mushrooms by at least a part of the contour of the mushrooms in addition to the image detection means 21 for detecting the degree of plant growth by an image as in this embodiment. Is also used. In this case, for example, a configuration is adopted in which a plurality of optoelectronic sensors are arranged with a mushroom in between, and the growth degree of the mushroom is detected from the height of the umbrella. By using such a detection sensor as the detection means, it becomes possible to easily detect the growth of mushrooms and to detect plants in a small installation space. In addition to the above-described optoelectronic sensor, various sensors such as a contact sensor can be used as the detection sensor.
