Abstract
Description
[Technical field]
[0001] The present invention relates to Silkworm Rearing System Regarding. [Background technology]
[0002] 2. Description of the Related Art Silkworm rearing containers for rearing silkworms are known. Silkworms and food are contained in the silkworm rearing container. The silkworms in the silkworm rearing container grow by eating the food in the silkworm rearing container.
[0003] When raising silkworms, it is generally necessary to feed them with mulberry leaves and other foods every day (except during the sleeping period). The larval stage of silkworms lasts about 25 days, during which they molt four times. Then, in the fifth and final stage, silkworms synthesize silk proteins in their bodies, spin a thread of about 1,200 meters, and use that thread to make a cocoon.
[0004] As a related technique, Patent Document 1 describes a sericulture method. In the sericulture method described in Patent Document 1, a sheet of sericulture feed is laid on a flat pallet, and a net is placed on top of it. The net is used by the silkworms to hold on to when they molt.
[0005] Attempts to reduce the labor required for sericulture have been introduced in the past. Patent Document 2 describes a method for rearing silkworms using artificial feed, in which the work is simplified by using an arm to transfer rearing trays stacked in multiple tiers and to move rearing nets in which silkworms are reared. Patent Document 1 also describes that when rearing silkworms in a sterile room, the work process is simplified to reduce the intrusion of germs from the outside and the effects of bacteria falling inside the room.
[0006] Patent Document 3 describes a silkworm rearing device in which rearing cages 10 housed on multiple rearing shelves are circulated using a driving device and automatically transported to a work opening in order to reduce labor when rearing large numbers of silkworms.

[0008] However, in Patent Document 1, most of the silkworm rearing is done manually. This increases the cost of rearing silkworms. In addition, because most of the silkworm rearing is done manually, there is a relatively high risk of bacteria being introduced into the rearing environment of the silkworms.
[0009] In addition, in the silkworm rearing method described in Patent Document 2, an arm can be used to transfer rearing trays containing artificial feed and move rearing nets, but the supply of feed and the installation of agricultural equipment cannot be automated, and all processes in sericulture are not automated.
[0010] In the silkworm rearing apparatus described in Patent Document 3, the rearing cages 10 are circulated by a driving device and automatically transported to the work opening, but the attachment and detachment of plastic bags, replacement of rearing cages, etc. cannot be automated, and all of the sericulture processes are not automated.
[0011] The object of the present invention is to enable rearing of silkworms in a sterile environment and to automate all the steps of sericulture. Silkworm Rearing System The purpose of this invention is to provide [Means for solving the problem]

[0015] Hereinafter, an automatic sericulture system, an automatic sericulture method, a program, and a storage medium according to an embodiment of the present invention will be described with reference to the drawings. However, the embodiments shown below are examples of an automatic sericulture system, an automatic sericulture method, a program, and a storage medium for embodying the technical ideas of the present invention, and do not limit the present invention to these, but can be equally applied to other embodiments included in the scope of the claims. In the following description, the same reference numerals are used for members and parts having the same functions, and repeated description of members and parts with the same reference numerals is omitted.
[0016] [First embodiment] A silkworm rearing system 1A and a silkworm rearing method according to the first embodiment will be described with reference to Figures 1 and 2. Figure 1 is a schematic diagram of a silkworm rearing system 1A according to the first embodiment. Figure 2 is a flowchart showing an example of a silkworm rearing method according to the first embodiment.
[0017] The silkworm rearing system 1A in the first embodiment includes a silkworm transfer device 10 that transfers silkworms from a first rearing container C1 to a second rearing container C2, and a second rearing container transport device 20 that transports the second rearing container C2.
[0018] It is preferable that a plurality of silkworms A are collectively reared inside the first rearing container C1. In other words, it is preferable that the first rearing container C1 is a container for collectively rearing a plurality of silkworms in a rearing room. For example, 10 to 1000 silkworms, 30 to 500 silkworms, or 50 to 300 silkworms are collectively reared inside the first rearing container C1. The area of the rearing region in one first rearing container C1 (area in a plan view) is, for example, 100 cm. 2 More than 10000cm 2 Below, 400cm 2 More than 4900cm 2 Below, 900cm 2 More than 2500cm 2 The first breeding container C1 is, for example, a container with an open top.
[0019] It is preferable that a plurality of silkworms A are individually raised inside the second rearing container C2. In other words, it is preferable that the second rearing container C2 is an individual rearing container for individually rearing one silkworm in each rearing chamber. In the example shown in FIG. 1, the second rearing container C2 includes a plurality of rearing chambers SP isolated from each other. In the example shown in FIG. 1, the second rearing container C2 includes a first rearing chamber SP1 and a second rearing chamber SP2, and the first rearing chamber SP1 and the second rearing chamber SP2 are isolated from each other. The number of rearing chambers SP included in the second rearing container C2 is, for example, 10 or more, 30 or more, or 50 or more.
[0020] Each breeding chamber SP may be defined by an independent cylindrical container, or may be defined by a partition wall disposed within a housing member (e.g., within a container or frame). In other words, the second breeding container C2 may be an assembly of multiple cylindrical containers, or may have multiple partition walls disposed inside a housing member that defines an outer wall.
[0021] The silkworm transfer device 10 transfers the silkworms A from the first rearing container C1 to the second rearing container C2.
[0022] In the example shown in Figure 1, the silkworm transfer device 10 transfers silkworm A from the first rearing container C1 to the second rearing container C2 so that only one silkworm A is housed in each rearing room SP (for example, only one silkworm is housed in the first rearing room SP1 and only one silkworm is housed in the second rearing room SP2).
[0023] The silkworm transfer device 10 includes, for example, a silkworm holding member 11 and a holding member moving device 12 for moving the silkworm holding member 11 from the first rearing container C1 to the second rearing container C2. The silkworm transfer device 10 may include a camera 13 capable of capturing images of the silkworms.
[0024] The silkworm holding member 11 is a member capable of holding a silkworm. The silkworm holding member 11 may include a first holding portion 11a and a second holding portion 11b. In this case, the silkworm holding member 11 can hold one silkworm by reducing the distance between the first holding portion 11a and the second holding portion 11b. Alternatively or additionally, the silkworm holding member 11 may include a vacuum suction portion 11c capable of suctioning the epidermis of the silkworm.
[0025] The holding member moving device 12 is, for example, a device capable of three-dimensionally changing the position of the silkworm holding member 11. The holding member moving device 12 is, for example, a robot arm.
[0026] The camera 13 captures images of the silkworms A in the first rearing container C1 based on a control command from the control device 30. The image data acquired by the camera 13 is transmitted to the control device 30 by wire or wirelessly. The control device 30 determines the position and posture of each of the silkworms based on the image data. The control device 30 controls the holding member moving device 12 and the silkworm holding member 11 based on the determination result. The silkworm holding member 11 controlled by the control device 30 holds one silkworm. Thereafter, the control device 30 controls the holding member moving device 12 to move the silkworm holding member 11 toward one rearing room SP (e.g., the first rearing room SP1) of the second rearing container C2. The control device 30 controls the silkworm holding member 11 to release the silkworm holding member 11 from its holding. As a result, the silkworms are housed in one rearing room SP (e.g., the first rearing room SP1) of the second rearing container C2.
[0027] The operation of transferring the silkworms in the first rearing container C1 to one rearing room SP of the second rearing container C2 is repeatedly executed. For example, after one silkworm is housed in the first rearing room SP1, the camera 13 again captures an image of the multiple silkworms in the first rearing container C1 based on a control command from the control device 30. The image data acquired by the camera 13 is transmitted to the control device 30. The control device 30 determines the position and posture of each of the multiple silkworms based on the image data. The control device 30 controls the holding member moving device 12 and the silkworm holding member 11 based on the determination result. The silkworm holding member 11 controlled by the control device 30 holds one silkworm. Thereafter, the control device 30 controls the holding member moving device 12 to move the silkworm holding member 11 toward one rearing room SP (e.g., the second rearing room SP2) of the second rearing container C2. The control device 30 controls the silkworm holding member 11 to release the silkworms from the silkworm holding member 11. As a result, the silkworms are housed in one rearing room SP (for example, the second rearing room SP2) of the second rearing container C2.
[0028] The second rearing container transport device 20 moves the second rearing container C2 from the silkworm transfer area AR to the second rearing container storage area AR2. The silkworm transfer area AR is an area where the silkworms A are transferred from the first rearing container C1 to the second rearing container C2. On the other hand, the second rearing container storage area AR2 is an area where the second rearing container C2 is stored. In the example shown in FIG. 1, a shelf T2 is arranged in the second rearing container storage area AR2, and the second rearing container C2 is stored on the shelf T2.
[0029] In the example shown in FIG. 1, the shelf T2 is a fixed shelf installed in the second rearing container storage area AR2. The second rearing container transport device 20 transports the second rearing container C2 between the silkworm transfer area AR and the second rearing container storage area AR2. Alternatively, the second rearing container transport device 20 may transport the shelf T2 on which the second rearing container C2 is placed between the silkworm transfer area AR and the second rearing container storage area AR2. In other words, the shelf T2 may be a movable shelf.
[0030] When the second rearing container C2 is in the second rearing container storage area AR2, the silkworms in the second rearing container C2 eat the food F and grow.
[0031] The second breeding container transport device 20 may include a conveyor such as a belt conveyor or a roller conveyor. Alternatively or additionally, the second breeding container transport device 20 may include a transport device (e.g., a stacker crane) with a transfer device that transfers the second breeding container C2 to the shelf T2. Based on a command from the control device 30, the second breeding container transport device 20 transports the second breeding container C2 to a predetermined storage position (an empty storage position among the multiple storage positions) in the second breeding container storage area AR2. The second breeding container transport device 20 is driven, for example, by a motor.
[0032] The control device 30 controls the operation of the silkworm transfer device 10 and / or the second rearing container transport device 20. The number of computers included in the control device 30 may be one or more. In other words, one computer may function as the control device 30, or multiple computers may function as the control device 30 by cooperating with each other.
[0033] The silkworm rearing system 1 in the first embodiment includes a silkworm transfer device 10 and a second rearing container transport device 20. Therefore, the transfer of silkworms from the first rearing container C1 to the second rearing container C2 and the movement of the second rearing container C2 to which the silkworms have been transferred can be automated. As a result, the rearing of silkworms is made more efficient. In addition, since the transfer of silkworms and the movement of the second rearing container C2 are not performed manually, there is substantially no contamination of the silkworm rearing environment with germs.
[0034] In the first embodiment, the silkworm rearing system 1A may include a first rearing container transport device 40 that transports the first rearing container C1 from the first rearing container storage area AR1 to the silkworm transfer area AR. The first rearing container transport device 40 is preferably a transport device separate from the second rearing container transport device 20. The first rearing container transport device 40 includes a conveyor such as a belt conveyor or a roller conveyor. The first rearing container transport device 40 may include a transport device with a transfer device that transfers the first rearing container C1 to the shelf T1. The first rearing container transport device 40 is driven, for example, by a motor.
[0035] When the silkworm rearing system 1A includes the first rearing container transport device 40, the movement of the first rearing container C1 to the silkworm transfer area AR can be automated. As a result, the rearing of silkworms becomes more efficient. In addition, since the movement of the first rearing container C1 is not performed manually, there is substantially no risk of bacteria being introduced into the rearing environment of the silkworms.
[0036] In the example shown in Fig. 1, a shelf T1 is arranged in the first rearing container storage area AR1, and a first rearing container C1 is stored on the shelf T1. When the first rearing container C1 is in the first rearing container storage area AR1, the silkworms in the first rearing container C1 eat food and grow.
[0037] In the first embodiment, the first rearing container storage area AR1 is preferably arranged in a sterile atmosphere AT. The second rearing container storage area AR2 is preferably arranged in a sterile atmosphere AT. Similarly, the silkworm transfer area AR is preferably arranged in a sterile atmosphere AT. In this specification, the sterile atmosphere AT means an atmosphere in a space substantially isolated from the outside, and set so that the amount of microorganisms present is less than that of the outside. The cleanliness in the sterile atmosphere AT is, for example, Class 6 to Class 8, more preferably Class 7 or less, according to the ISO standard (ISO14644-1:2015). The cleanliness level of Class 6 is equivalent to Class 1000 of the US Federal Standard FED-STD 209E, the cleanliness level of Class 7 is equivalent to Class 10000 of the US Federal Standard FED-STD 209E, and the cleanliness level of Class 8 is equivalent to Class 100000 of the US Federal Standard FED-STD 209E.
[0038] (Silkworm rearing method) Next, an example of a silkworm rearing method in the first embodiment will be described.
[0039] In a first step ST1, a plurality of silkworms are reared in a first rearing container C1. The first step ST1 is a first silkworm rearing step. In the first silkworm rearing step, for example, a plurality of silkworms A are collectively reared in the first rearing container C1.
[0040] In a second step ST2, the silkworms in the first rearing container C1 are transferred to the second rearing container C2 using a silkworm transfer device 10.
[0041] The second step ST2 may include a first transporting step of transporting the first rearing container C1 to the silkworm transfer area AR, a second transporting step of transporting the second rearing container C2 to the silkworm transfer area AR, and a transfer step of transferring multiple silkworms A from the first rearing container C1 to the second rearing container C2 using the silkworm transfer device 10.
[0042] The first transfer step is performed, for example, by using the first breeding container transfer device 40. The second transfer step is performed, for example, by using the second breeding container transfer device 20. The second transfer step may be performed before the first transfer step, after the first transfer step, or simultaneously with the first transfer step.
[0043] In the example shown in FIG. 1, the second rearing container C2 includes a plurality of rearing rooms SP for individual rearing. In this case, the second step ST2 (silkworm transfer process) may include transferring a plurality of silkworms A reared in the first rearing container C1 to a plurality of rearing rooms SP, respectively. In the example shown in FIG. 1, the silkworm transfer device 10 transfers a plurality of silkworms A reared collectively in the first rearing container C1 to a plurality of rearing rooms SP for individual rearing, respectively. Therefore, it is possible to smoothly switch from collective rearing to individual rearing without introducing germs into the rearing environment of the silkworms. Note that the silkworm transfer process (i.e., the silkworm transfer process of transferring silkworms A from the first rearing container C1 to the second rearing container C2) performed by the silkworm transfer device 10 may include transferring the silkworms in the first rearing container C1 to the food support part PL (see FIG. 14) in the second rearing container C2. Alternatively, the silkworm transfer process performed by the silkworm transfer device 10 (i.e., the silkworm transfer process of transferring silkworms A from the first rearing container C1 to the second rearing container C2) may include transferring the silkworms in the first rearing container C1 to a food support part PL (see Figure 5) outside the second rearing container C2, and inserting the food support part PL on which the silkworms A are supported into the second rearing container C2.
[0044] After the second step ST2 is performed, the second rearing container C2 to which the plurality of silkworms A have been transferred is transported from the silkworm transfer area AR to the second rearing container storage area AR2. The transport is performed, for example, by using the second rearing container transport device 20.
[0045] In the third step ST3, a plurality of silkworms A are reared in the second rearing container C2. The third step ST3 is a second silkworm rearing step. In the second silkworm rearing step, for example, each of the plurality of silkworms A is individually reared in an independent rearing room SP.
[0046] In the silkworm rearing method of the first embodiment, the silkworms are transferred from the first rearing container C1 to the second rearing container C2 by the silkworm transfer device 10. Therefore, the transfer of the silkworms from the first rearing container C1 to the second rearing container C2 can be automated. As a result, the rearing of the silkworms is made more efficient. In addition, since the transfer of the silkworms is performed by the silkworm transfer device 10, there is substantially no contamination of the silkworm rearing environment with germs.
[0047] In the first embodiment, when a plurality of silkworms A are collectively reared in the first rearing container C1 and each of the plurality of silkworms A is individually reared in the second rearing container C2, the younger silkworms can be collectively reared efficiently in a small space, and the older silkworms can be individually reared with reduced stress. Thus, in the first embodiment, it is possible to achieve both space saving for rearing silkworms, efficient rearing of silkworms, and reduction of stress on silkworms. Furthermore, when silkworms are made to form cocoons in a rearing room for individual rearing, the location where the cocoons are formed can be localized. In this case, it becomes easy to collect the cocoons (for example, by a robot).
[0048] [Second embodiment] A silkworm rearing system 1B and a silkworm rearing method according to the second embodiment will be described with reference to Figs. 3 to 16. Fig. 3 is a schematic plan view of the silkworm rearing system 1B according to the second embodiment (schematic plan view showing the interior of the container 2). Fig. 4 is a schematic perspective view of the silkworm rearing system 1B according to the second embodiment. Fig. 5 is a schematic view of an example of a feed supplying device 60.

Fig. 10 is a schematic perspective view showing an example of the first rearing container C1. Fig. 11 is a schematic cross-sectional view showing an example of an egg transfer device 80. Fig. 12 is a schematic front view showing an example of an egg transfer device 80. Fig. 13 is a diagram showing a silkworm rearing system 1B in the second embodiment. Fig. 14 is a schematic perspective view showing an example of the second rearing container C2. Fig. 15 is a schematic perspective view showing an example of the second rearing container C2. Fig. 16 is a flowchart showing an example of a silkworm rearing method in the second embodiment.
[0049] The silkworm rearing system 1B in the second embodiment includes a container 2 in which at least one of the devices constituting the silkworm rearing system 1B is disposed. In the second embodiment, differences from the first embodiment will be mainly described, and repetitive descriptions of matters already described in the first embodiment will be omitted. Therefore, it goes without saying that matters already described in the first embodiment can be applied to the second embodiment even if they are not explicitly described in the second embodiment. This also applies to other embodiments.
[0050] The silkworm rearing system 1B includes, for example, at least one of a silkworm transfer device 10, a first rearing container transport device 40, a second rearing container transport device 20, and a control device 30. The silkworm transfer device 10, the first rearing container transport device 40, the second rearing container transport device 20, and the control device 30 have been described in the first embodiment, so repeated description of these components will be omitted.
[0051] 3, the silkworm rearing system 1B includes two containers 2 (more specifically, a first container 2A and a second container 2B). However, the number of containers 2 included in the silkworm rearing system 1B may be one, or three or more.
[0052] In the example shown in Fig. 3, the second breeding container transport device 20 is disposed in the container 2 (more specifically, the second container 2B). The container 2 can define a substantially closed space (more specifically, a sterile atmosphere AT). Therefore, when the second breeding container transport device 20 is disposed in the container 2, it is difficult for germs to enter the transport path of the second breeding container C2.
[0053] When the transport device is installed in a closed space, the transport device is generally installed in a building that defines the closed space. In contrast, in the second embodiment, the transport device, such as the second breeding container transport device 20, is arranged in the container 2. Even when the container 2 is arranged outdoors, it is possible to define a substantially closed space. Therefore, it is not necessary to construct a new building to arrange the transport device. Furthermore, even when the container 2 is arranged in an existing building, the container 2 defines a substantially closed space, so that the existing building is not required to have a high degree of airtightness. Furthermore, since the container 2 can be transported by a vehicle, a ship, or the like, the container 2 can be arranged with a high degree of freedom. In addition, it is also easy to move a container that has been arranged in a predetermined place to another location.
[0054] The container 2 is, for example, a portable container standardized by ISO668 (for example, ISO668:1995, ISO668:2005, ISO668:2013, etc.). The container 2 is, for example, a 45-foot container (ISO668 "1EEE" container, "1EE" container, etc.), a 40-foot container (ISO668 "1AAA" container, "1AA" container, "1A" container, "1AX" container, etc.), a 30-foot container (ISO668 "1BBB" container, "1BB" container, "1B" container, "1BX" container, etc.), a 20-foot container (ISO668 "1CC" container, "1C" container, "1CX" container, etc.), a 10-foot container (ISO668 "1D" container, "1DX" container, etc.), a 6.5-foot container (ISO668 "1E" container, etc.), or a 5-foot container (ISO668 "1F" container, etc.). Hereinafter, in this specification, a portable container standardized by ISO 668 will be referred to as an "ISO container."
[0055] (1st Container 2A) In the example shown in Fig. 1, the silkworm rearing system 1B has a first container 2A. The first container 2A is, for example, an ISO container. The length of the first container 2A is, for example, 45 feet, 40 feet, 30 feet, 20 feet, 10 feet, 6.5 feet, or 5 feet.
[0056] In the example shown in Fig. 1, the first container 2A has a first breeding container storage area AR1. In the example shown in Fig. 1, a heat insulating material 91 is arranged along an inner surface Ws of an outer wall Wa of the first container 2A. In addition, an air conditioner 92 that adjusts the temperature inside the first container 2A is arranged in the first container 2A.
[0057] When the silkworm rearing system 1B includes the first container 2A having the first rearing container storage area AR1, the heat insulating material 91, and the air conditioner 92, it is possible to set the silkworm rearing environment in the first rearing container C1 to a suitable environment. The air conditioner 92 may be an air conditioner capable of adjusting the temperature, or may be an air conditioner capable of adjusting the temperature and humidity. The air conditioner 92 maintains the temperature of the first rearing container storage area AR1 at, for example, 20 degrees Celsius or higher and 35 degrees Celsius or lower, or 25 degrees Celsius or higher and 30 degrees Celsius or lower.
[0058] When the air conditioner 92 is operated, the pressure inside the first container 2A is set to be higher than the pressure outside the first container 2A. The pressure difference between the pressure inside the first container 2A and the pressure outside the first container 2A is, for example, 10 Pa (Pascal) or more, 100 Pa or more, 1000 Pa or more, 3000 Pa or more, or 5000 Pa or more. By setting the pressure inside the first container 2A to be higher than the pressure outside the first container 2A, the risk of bacteria being mixed into the first container 2A is reduced.
[0059] When the air conditioner 92 is operated, the pressure in the first breeding container storage area AR1 is preferably set to be higher than the pressure in the area outside the first breeding container storage area AR1 in the first container 2A. The pressure difference between the two areas is, for example, 10 Pa (Pascal) or more, 100 Pa or more, or 1000 Pa or more. By setting the pressure in the first breeding container storage area AR1 to be higher than the pressure in the area outside the first breeding container storage area AR1, the risk of bacteria being mixed into the first breeding container storage area AR1 is reduced. In order to make the pressure in the first breeding container storage area AR1 higher than the pressure in the area outside the first breeding container storage area AR1, the air supply port 92a of the air conditioner 92 may be disposed in the first breeding container storage area AR1.
[0060] The air conditioning unit 92 includes a fan 921 that supplies air from outside the first container 2A to inside the first container 2A, a heat exchanger 922 that raises or lowers the temperature of the air, and a filter 923 (e.g., a HEPA filter) that removes germs from the air.
[0061] The air conditioner 92 may include a circulation flow path that circulates the air in the first container 2A within the first container 2A, and a filter 924 (e.g., a HEPA filter) disposed in the circulation flow path. When the air conditioner 92 includes the circulation flow path and the filter 924, germs that have entered the first container 2A are removed by the filter 924.
[0062] (Second container 2B) In the example shown in Fig. 3, the silkworm rearing system 1B has a second container 2B. The second container 2B is, for example, an ISO container. The length of the second container 2B is, for example, 45 feet, 40 feet, 30 feet, 20 feet, 10 feet, 6.5 feet, or 5 feet.
[0063] In the example shown in FIG. 3, the second container 2B has a second breeding container storage area AR2. In the example shown in FIG. 3, a heat insulating material 91 is arranged along the inner surface Ws of the outer wall Wa of the second container 2B. In addition, an air conditioner 92 that adjusts the temperature inside the second container 2B is arranged in the second container 2B. The air conditioner 92 arranged in the second container 2B is an air conditioner similar to the air conditioner 92 arranged in the first container 2A. The air conditioner 92 arranged in the second container 2B includes a fan 921, a heat exchanger 922, filters (923, 924), etc., similar to the air conditioner 92 arranged in the first container 2A. The air conditioner 92 arranged in the second container 2B maintains the temperature of the second breeding container storage area AR2 at, for example, 20 degrees Celsius or more and 35 degrees Celsius or less, or 25 degrees Celsius or more and 30 degrees Celsius or less.
[0064] When the air conditioner 92 is operated, the pressure inside the second container 2B is set to be higher than the pressure outside the second container 2B. The pressure difference between the pressure inside the second container 2B and the pressure outside the second container 2B is, for example, 10 Pa (Pascal) or more, 100 Pa or more, 1000 Pa or more, 3000 Pa or more, or 5000 Pa or more.
[0065] When the air conditioner 92 is operated, the pressure in the second breeding container storage area AR2 is preferably set to be higher than the pressure in the area outside the second breeding container storage area AR2 in the second container 2B. The pressure difference between the two areas is, for example, 10 Pa (Pascal) or more, 100 Pa or more, or 1000 Pa or more. In order to make the pressure in the second breeding container storage area AR2 higher than the pressure in the area outside the second breeding container storage area AR2, an air supply port 92a of the air conditioner 92 may be disposed in the second breeding container storage area AR2.
[0066] In the example shown in FIG. 3, the silkworm rearing system 1B has a first container 2A having a first rearing container storage area AR1 and a second container 2B having a second rearing container storage area AR2. The second container 2B is a container separate from the first container 2A. In this case, the silkworm rearing system 1B can set a rearing environment (first container 2A) for rearing relatively young silkworms and a rearing environment (second container 2B) for rearing relatively old silkworms independently. For example, it is possible to rear a large number of silkworms in a relatively small space by rearing relatively young silkworms in a group. On the other hand, it is possible to reduce the stress acting on the silkworms by rearing relatively old silkworms individually.
[0067] It should be noted that a relatively large rearing space is required for silkworms that are relatively old. Therefore, the size of the second container 2B having the second rearing container storage area AR2 may be larger than the size of the first container 2A having the first rearing container storage area AR1. Alternatively, or additionally, a plurality of containers 2 may be arranged so that the number of the second containers 2B having the second rearing container storage area AR2 is greater than the number of the first containers 2A having the first rearing container storage area AR1. For example, one first container 2A may be connected to two or more second containers 2B. The number of the second containers 2B connected to the first container 2A may be three or more, five or more, or ten or more.
[0068] (Container connection section 95) In the example shown in FIG. 3, the silkworm rearing system 1B includes a container connector 95 that connects the first container 2A and the second container 2B. The presence of the container connector 95 suppresses the intrusion of germs into the first container 2A or the second container 2B. More specifically, when the first rearing container C1, the second rearing container C2, etc. are transported between the first container 2A and the second container 2B, germs may intrude through the opening of the first container 2A or the opening of the second container 2B. In the example shown in FIG. 3, the first container 2A and the second container 2B are connected by the container connector 95 (more specifically, the opening of the first container 2A and the opening of the second container 2B are covered by the container connector 95), so that the risk of germs intruding through these openings is reduced. The container connector 95 may be made of a flexible member made of a synthetic resin such as vinyl, may be made of a rigid member such as a metal plate, or may be made of a combination of a flexible member and a rigid member.
[0069] 3, a first door DR1 is disposed at the opening of the first container 2A, and a second door DR2 is disposed at the opening of the second container 2B. However, the first door DR1 and / or the second door DR2 may be omitted.
[0070] (Food supply device 60) In the example shown in FIG. 3, the silkworm rearing system 1B includes a feed supplying device 60. The feed supplying device 60 is a device that supplies feed (silkworm feed) to the first rearing container C1 or the second rearing container C2. When the silkworm rearing system 1B includes the feed supplying device 60, the supply of feed to the first rearing container C1 or the second rearing container C2 can be automated. In this case, the introduction of germs into the silkworm rearing environment is suppressed when the feed is supplied.
[0071] In the example shown in FIG. 3, the feed supplying device 60 is disposed in the first container 2A. Alternatively, or additionally, the feed supplying device 60 may be disposed in the second container 2B. When the feed supplying device 60 is disposed in the container 2, contamination of the silkworm rearing environment with germs during the supply of feed is more effectively prevented. However, when the silkworm rearing system 1B does not have the above-mentioned container 2, the feed supplying device 60 may be disposed in any location other than the container 2.
[0072] An example of the food supplying device 60 will be described with reference to Fig. 5. The food supplying device 60 includes a food storage container 61, a nozzle member 62, a moving device 63, a food supplying pipe 64, and a food supplying pump 65, for example.
[0073] The feed storage container 61 is a container for temporarily storing feed for silkworms. For example, mulberry F1 (more specifically, powdered mulberry leaves), soybean pulp F2, and water are put into the feed storage container 61. In the example shown in Fig. 5, mulberry F1 is put into the feed storage container 61 from the mulberry container, and soybean pulp F2 is put into the feed storage container 61 from the soybean pulp container. The putting in may be performed automatically by a mulberry supplying device and / or a soybean pulp supplying device, or may be performed manually.
[0074] In the example shown in FIG. 5, a water supply pipe 67 is connected to the bait storage container 61. The water supply pipe 67 is automatically used to supply water to the bait storage container 61. In the example shown in FIG. 5, an on-off valve 671 and a filter 672 are disposed in the water supply pipe 67. The on-off valve 671 and the control device 30 are connected to each other by wire or wirelessly so as to be capable of transmitting signals, and the on-off valve 671 is opened and closed based on a command from the control device 30. When the on-off valve 671 is open, water is supplied to the bait storage container 61, and when the on-off valve is closed, water is not supplied to the bait storage container 61. The filter 672 removes foreign matter or germs from the water.
[0075] In the example shown in Fig. 5, mulberry, soybean pulp, and water introduced into the feed storage container 61 are stirred in the feed storage container 61. The stirring is performed by a stirrer 611 driven by a motor M1. The motor M1 and the control device 30 are connected to each other by wire or wirelessly so as to be capable of transmitting signals, and the motor M1 is driven based on a command from the control device 30. When the motor M1 is driven, the stirrer 611 stirs the mixed feed containing mulberry, soybean pulp, and water.
[0076] Mixed feed (more specifically, paste feed) containing mulberry, soybean pulp, and water is supplied from a feed storage container 61 toward a nozzle member 62 by a feed supply pump 65. In the example shown in FIG. 5, the feed supply pump 65 may include a screw conveyor or a snake pump. In the example shown in FIG. 5, the feed supply pump 65 includes a motor M2 and a rotating shaft 651 driven by the motor M2. The feed supply pump 65 may include a blade member 652 attached to the rotating shaft 651. Alternatively or additionally, the rotating shaft 651 may be a non-linear rotating shaft (for example, a spiral-shaped rotating shaft). In this case, the blade member 652 may be omitted.
[0077] The motor M2 and the control device 30 are connected to each other by wire or wirelessly so that signals can be transmitted, and the motor M2 is driven based on a command from the control device 30. When the motor M2 is driven, the rotating shaft 651 rotates. As a result, the rotating shaft 651 or the blade member 652 attached to the rotating shaft 651 pushes out bait (kneaded bait) from the upstream side of the bait supply pump 65 toward the downstream side of the bait supply pump 65. In the example shown in FIG. 5, the outlet of the bait storage container 61 and the upstream side of the bait supply pump 65 are connected. Then, the bait (kneaded bait) discharged from the outlet of the bait storage container 61 is supplied to the upstream side of the bait supply pump 65. In the example shown in FIG. 5, the bait discharged from the bait supply pump 65 is supplied to the nozzle member 62 through the bait supply pipe 64.
[0078] The food supply pipe 64 may be a rigid pipe, a flexible pipe, or a pipe having a part which is a rigid pipe and another part which is a flexible pipe.
[0079] 5, the food supply pipe 64 is a pipe that connects the food storage container 61 and the nozzle member 62. The above-mentioned food supply pump 65 is disposed midway along the food supply pipe 64.
[0080] 5, an on-off valve 641 is disposed in the food supply pipe 64. The on-off valve 641 and the control device 30 are connected to each other by wire or wirelessly so as to be capable of transmitting signals, and the on-off valve 641 is opened and closed based on a command from the control device 30. When the on-off valve 641 is open, food is supplied to the nozzle member 62-1, and when the on-off valve 641 is closed, food is not supplied to the nozzle member 62-1.
[0081] 5, the food supply pipe 64 includes a main pipe 64m and a first branch pipe 64d. The first branch pipe 64d is provided with the on-off valve 641 described above, and is connected to the nozzle member 62-1 described above.
[0082] The food supply pipe 64 may include a second branch pipe 64e. In the example shown in Fig. 5, an on-off valve 643 is disposed in the second branch pipe 64e, and the second branch pipe 64e is connected to the second nozzle member 62-2. The on-off valve 643 and the control device 30 are connected to each other by wire or wirelessly so as to be capable of transmitting signals, and the on-off valve 643 is opened and closed based on a command from the control device 30.
[0083] In the example shown in Fig. 5, the main pipe 64m and the first branch pipe 64d are connected via a branch portion D1, and the main pipe 64m and the second branch pipe 64e are connected via a branch portion D2.
[0084] In the example shown in Fig. 5, the bait supply pipe 64 includes a return pipe 64r. When the bait supply pipe 64 includes the return pipe 64r, surplus bait that is not supplied to the nozzle member 62 among the bait flowing through the main pipe 64m is returned to the bait storage container 61 via the return pipe 64r. In the example shown in Fig. 5, the portion of the bait supply pipe 64 between the branch D1 and the bait storage container 61 constitutes the return pipe 64r. An opening / closing valve 645 may be arranged in the return pipe 64r.
[0085] The nozzle member 62 (nozzle member 62-1 or second nozzle member 62-2) has an opening 62h for discharging bait. In the example shown in FIG. 5, the nozzle member 62-1 has a plurality of nozzles including a first nozzle 621 and a second nozzle 622. The opening area (or diameter) of the discharge portion (first opening) of the first nozzle 621 is smaller than the opening area (or diameter) of the discharge portion (second opening) of the second nozzle 622. The opening area (or diameter) of the discharge portion (second opening) of the second nozzle 622 is smaller than the opening area (or diameter) of the discharge portion (third opening) of the third nozzle 623. The nozzle member 62-1 has a switching valve 620 that operates, for example, by a command from the control device 30. The switching valve 620 selectively supplies bait to one of the plurality of nozzles (621, 622, 623). More specifically, when the switching valve 620 is operated so that the feed supply pipe 64 and the first nozzle 621 communicate with each other based on a command from the control device 30, the feed is discharged from the opening of the first nozzle 621. Also, when the switching valve 620 is operated so that the feed supply pipe 64 and the second nozzle 622 communicate with each other based on a command from the control device 30, the feed is discharged from the opening of the second nozzle 622. The feed discharged from the second nozzle 622 is thicker than the feed discharged from the first nozzle 621. Also, when the switching valve 620 is operated so that the feed supply pipe 64 and the third nozzle 623 communicate with each other based on a command from the control device 30, the feed is discharged from the opening of the third nozzle 623. The feed discharged from the third nozzle 623 is thicker than the feed discharged from the second nozzle 622.
[0086] 5, the second nozzle member 62-2 includes one nozzle. The food discharged from the nozzle of the second nozzle member 62-2 is thicker than the food discharged from the nozzle of the nozzle member 62-1 (for example, the first nozzle 621, the second nozzle 622, or the third nozzle 623). Alternatively, the thickness of the food discharged from the nozzle of the second nozzle member 62-2 may be approximately the same as the thickness of the food discharged from the third nozzle 623.
[0087] The moving device 63 is a device that moves the nozzle member 62 relative to the bait support part PL. In the example shown in Fig. 5, the moving device 63 is a nozzle moving device that moves the nozzle member 62. Alternatively, the moving device 63 may be a device that moves the bait support part PL.
[0088] The moving device 63 and the control device 30 are connected to each other by wire or wirelessly so as to be capable of transmitting signals, and the moving device 63 operates based on a command from the control device 30. The moving device 63 changes the position of the nozzle member 62 in three dimensions based on a command from the control device 30. In the example shown in FIG. 5, the moving device 63 includes a robot arm 630.
[0089] In the example shown in FIG. 5, the moving device 63 (more specifically, the moving device 63-1) moves the nozzle member 62-1 relative to the bait support part PL. The bait support part PL is, for example, a bait support part arranged in the first rearing container C1. The bait support part PL is preferably made of a mesh-like member (in other words, a net-like member). In this case, the silkworm droppings fall below the bait support part PL through each opening of the mesh-like member. Therefore, the rearing environment for the silkworms is less likely to deteriorate in the area above the bait support part PL.
[0090] In the example shown in FIG. 5, the moving device 63 (more specifically, the second moving device 63-2) moves the second nozzle member 62-2 relative to the bait support part PL. The bait support part PL is, for example, a bait support part to be placed in the second rearing container C2. The bait support part PL is preferably made of a mesh-like member (in other words, a net-like member). In this case, the silkworm droppings fall below the bait support part PL through each opening of the mesh-like member. Therefore, the rearing environment for the silkworms is less likely to deteriorate in the area above the bait support part PL.
[0091] (Partition material P) In the example shown in FIG. 5, a partition member P is disposed inside the first rearing container C1. As shown in FIG. 6, the partition member P (more specifically, the first partition member P1) is a member that divides the space in the first rearing container C1 into a first region R1 in which silkworms are raised and a second region R2 in which the entrance of silkworms is restricted (i.e., a region into which silkworms cannot enter). The position of the partition member P can be changed between a first position (see the upper diagram of FIG. 6) in which the first region R1 and the second region R2 are separated, and a second position (see the lower diagram of FIG. 6) in which the partition state by the partition member is released. The first position (in other words, the partition position) is, for example, the position of the partition member P when the partition member P is disposed in the first rearing container C1. The second position (in other words, the non-partition position) is, for example, the position of the partition member P when the partition member P is removed from the first rearing container C1.
[0092] (Partition member moving device 70) 7, the silkworm rearing system 1B includes a partition member moving device 70 that moves a partition member P arranged in the first rearing container C1. The partition member moving device 70 moves the partition member P, for example, from a first position in the first rearing container C1 to a second position outside the first rearing container C1.
[0093] In the example shown in FIG. 7, the partition member moving device 70 includes a partition member holding part 71 and a holder moving device 72. The partition member holding part 71 is a part capable of holding a partition member P. The partition member holding part 71 may include a first grip part 71a and a second grip part 71b. In this case, the partition member holding part 71 can hold the partition member P by reducing the distance between the first grip part 71a and the second grip part 71b. Alternatively, the partition member holding part 71 may include a hook part 71c (if necessary, see FIG. 5) from which the partition member P can be suspended.
[0094] The holder moving device 72 includes, for example, a robot arm. The robot arm of the holder moving device 72 may be the robot arm 630 of the moving device 63-1 shown in Fig. 5, or may be a robot arm different from the robot arm 630 of the moving device 63-1. Note that the shape and structure of the partition member moving device 70 are not particularly limited as long as it is a device capable of moving the partition member P.
[0095] The partition member moving device 70 and the control device 30 are connected to each other by wire or wirelessly so as to be capable of transmitting signals, and the partition member moving device 70 operates based on commands from the control device 30. More specifically, the partition member holding part 71 of the partition member moving device 70 holds the partition member P based on commands from the control device 30. Thereafter, the holder moving device 72 of the partition member moving device 70 moves the partition member holding part 71 in the direction from the first position toward the second position based on commands from the control device 30. In this way, the partition member P is removed from the first breeding container C1.
[0096] (First silkworm rearing process) An example of the first rearing step (the above-mentioned first step ST1) of rearing a plurality of silkworms A in the first rearing container C1 will be described in more detail with reference to Figs. 8 and 9.
[0097] In step ST201, a plurality of silkworms are raised in a first area R1 on one side of a first partition member P1 arranged in a first rearing container C1. Step ST201 is performed, for example, in a first rearing container C1 arranged in a first rearing container storage area AR1. In the example shown in FIG. 9(b), a plurality of first rearing containers C1 are accommodated in the first rearing container storage area AR1. The number of first rearing containers C1 accommodated in the first rearing container storage area AR1 is, for example, 10 or more, 50 or more, or 100 or more.
[0098] In step ST201, the first area R1 is provided with food F and a plurality of silkworms A. In addition, in step ST201, the second area R2 is provided with no food F or silkworms A.
[0099] Silkworm food F is supplied in advance to the first area R1 of the first rearing container C1. The supply of food to the first area R1 is performed, for example, through the nozzle member 62-1 (more specifically, the above-mentioned first nozzle 621) of the food supplying device 60 (see FIG. 9(a)). The thickness (in other words, the diameter) of the food supplied to the first area R1 is, for example, 3 mm or less, or 2 mm or less. The multiple silkworms A in the first area R1 grow by eating the food F in the first area R1. Note that if the food support part PL is a mesh-like member (in other words, a net-like member), the silkworm droppings M fall below the food support part PL. Therefore, the rearing environment of the silkworms on the food support part PL does not deteriorate.
[0100] In step ST202, the food F is supplied to the second area R2 on the other side of the first partition member P1. Step ST202 is performed, for example, after the first breeding container C1 is transported from the first breeding container storage area AR1 toward the food supplying device 60.
[0101] The feed F is supplied to the second region R2, for example, via the nozzle member 62-1 of the feed supplying device 60 (more specifically, the second nozzle 622 mentioned above) (see FIG. 9(c)). In step ST202, since there are no silkworms A in the second region R2, the silkworms A do not get in the way when supplying the feed F to the second region R2. It is preferable that the thickness of the feed F supplied from the second nozzle 622 is thicker than the thickness of the feed F supplied from the first nozzle 621. The thickness (in other words, the diameter) of the feed F supplied from the second nozzle 622 is, for example, 6 mm or less, or 5 mm or less.
[0102] In step ST203, the state (partition state) in which the first partition member P1 separates the first area R1 and the second area R2 is released (see FIG. 9(d)). The release is performed, for example, by the partition member moving device 70 moving the first partition member P1. In the example shown in FIG. 9(d), the release is performed by the partition member moving device 70 removing the first partition member P1 from the first breeding container C1. In the example shown in FIG. 9(d), the partition member moving device 70 has a hook portion 71c that can engage with the engagement portion Pa of the partition member P. Alternatively, the partition member moving device 70 may have a gripping portion that can grip the partition member P.
[0103] When the partition state by the first partition member P1 is released, the first area R1 and the second area R2 are combined to enlarge the area in which the multiple silkworms A are reared. This provides a more suitable rearing environment for the multiple silkworms that have grown in the first area R1.
[0104] After step ST203 is performed, the first rearing container C1 is transported to the first rearing container storage area AR1. In step ST202, fresh food F is supplied to the first rearing container C1. Thus, the multiple silkworms A eat the fresh food and further grow.
[0105] 9, in addition to the first partition member P1, a second partition member P2 is arranged in the first breeding container C1. The second partition member P2 is a member that separates the new first region Rn1 (enlarged first region) from the new second region Rn2 after the first partition member P1 is removed from the first breeding container C1 (see FIG. 9(d)).
[0106] When the second partition member P2 is disposed in the first breeding container C1, the food F is supplied to the new second area Rn2 in step ST204. Step ST204 is performed, for example, after the first breeding container C1 is transported from the first breeding container storage area AR1 toward the food supplying device 60.
[0107] The supply of food to the new second region Rn2 is performed, for example, via the nozzle member 62-1 of the food supplying device 60 (more specifically, the above-mentioned third nozzle 623) (see FIG. 9(e)). It is preferable that the thickness of the food F supplied from the third nozzle 623 is thicker than the thickness of the food F supplied from the second nozzle 622. The thickness (in other words, the diameter) of the food F supplied from the third nozzle 623 is, for example, 7 mm or less.
[0108] In step ST205, the state (partition state) in which the new first region Rn1 and the new second region Rn2 are separated by the second partition member P2 is released (see FIG. 9(f)). The release is performed, for example, by the partition member moving device 70 moving the second partition member P2. In the example shown in FIG. 9, the release is performed by the partition member moving device 70 removing the second partition member P2 from the first breeding container C1.
[0109] 9, the first breeding container C1 is a tray (in other words, a relatively shallow container with an open top). Since the top of the first breeding container C1 is open, the partition member P can be easily removed from the first breeding container C1.
[0110] In the example shown in FIG. 9, the number of partition members P arranged in the first breeding container C1 is two. Alternatively, the number of partition members P arranged in the first breeding container C1 may be one, or three or more. In the example shown in FIG. 6, the partition member P has an L-shape in plan view. However, the shape of the partition member P is not limited to the example shown in FIG. 6. For example, as shown in FIG. 10, the partition member P may have a rectangular frame shape in plan view.
[0111] (Egg transfer device 80) An example of an egg transfer device 80 for transferring silkworm eggs to a first rearing container C1 (for example, a tray) will be described with reference to Figs. 11 and 12.
[0112] The egg transfer device 80 transfers silkworm eggs E from a container C3 containing a plurality of silkworm eggs E to the first rearing container C1. When the silkworm rearing system 1 has the egg transfer device 80, the task of transferring silkworm eggs E to the first rearing container C1 (e.g., a tray) is automated. As a result, the rearing of silkworms is made more efficient. In addition, since the silkworm eggs E are automatically transferred by the egg transfer device 80, there is substantially no contamination of the rearing environment of the silkworms with harmful bacteria. The egg transfer device 80 is disposed, for example, in the container 2 (more specifically, in the first container 2A). When the egg transfer device 80 is disposed in the container 2, contamination of the rearing environment of the silkworms with harmful bacteria is more effectively suppressed.
[0113] 11, the egg transfer device 80 includes a suction tube 81 that sucks up the silkworm eggs E in the liquid, and a suction tube moving device 86 that moves the suction tube 81 relative to the first rearing container C1. In the liquid, dead silkworm eggs E1 tend to float more easily than live silkworm eggs E2. Therefore, by sucking up the silkworm eggs in the liquid (more specifically, silkworm eggs that have sunk in the liquid), it is possible to select and pick up live silkworm eggs E2.
[0114] The liquid in the container C3 is, for example, a disinfectant. The silkworm eggs E are sterilized by being immersed in the disinfectant in the container C3. In this case, the risk of bacteria being mixed into the first rearing container C1 is reduced when the silkworm eggs E are transferred to the first rearing container C1.
[0115] From the viewpoint of facilitating picking up of silkworm eggs E from the container C3, it is preferable that the tip of the container C3 has a tapered shape that becomes thinner toward the tip. By having the tip of the container C3 have a tapered shape, multiple silkworm eggs E tend to gather near the bottom of the container C3. Therefore, it is possible to position the tip of the suction tube 81 near the silkworm eggs E simply by inserting the suction tube 81 near the bottom of the container C3 (in other words, the deepest part of the container C3).
[0116] In the example shown in Fig. 11, the suction pipe 81 is connected to a vacuum pump 84 via a pipe 82. An on-off valve 83 is also provided in the pipe 82. With the tip of the suction pipe 81 positioned in the liquid in the container C3, the on-off valve 83 is opened, causing the suction pipe 81 to suck up one silkworm egg E. Alternatively, a suction force may be generated in the suction pipe 81 by moving a piston relative to a cylinder. In this case, the vacuum pump 84 may be omitted.
[0117] After the suction tube 81 has sucked up the silkworm eggs E, the suction tube moving device 86 moves the suction tube 81 in a direction from the container C3 toward the first rearing container C1. When the tip of the suction tube 81 comes above the first rearing container C1, the suction tube 81 releases the silkworm eggs E. This release may be performed by sending air into the suction tube 81, or by opening the suction tube 81 to the atmosphere.
[0118] In the example shown in FIG. 11, a partition member P is disposed in the first rearing container C1. In this case, it is preferable that the egg transfer device 80 transfers the silkworm eggs E only to the area (first area R1) on one side of the partition member P. In other words, it is preferable that the egg transfer device 80 does not transfer the silkworm eggs E to the area (second area R2) on the other side of the partition member P. If the partition member P is not disposed in the first rearing container C1, the egg transfer device 80 may transfer the silkworm eggs E to any position in the first rearing container C1.
[0119] The transfer of silkworm eggs E by the egg transfer device 80 may be performed after the food F is placed in the first rearing container C1 (more specifically, the first area R1), or may be performed before the food F is placed in the first rearing container C1 (more specifically, the first area R1).
[0120] 11, the suction tube moving device 86 can move the suction tube 81 along the vertical direction (in other words, the Z direction). Also, in the example shown in Fig. 11, the suction tube moving device 86 can move the suction tube 81 along the first horizontal direction (in other words, the X direction).
[0121] As shown in Fig. 12, the egg transfer device 80 may include a plurality of suction tubes 81. When the egg transfer device 80 includes a plurality of suction tubes 81, the egg transfer device 80 is able to simultaneously transfer a plurality of silkworm eggs to the first rearing container C1. In the example shown in Fig. 12, the egg transfer device 80 includes six suction tubes 81. Alternatively, the egg transfer device 80 may include one, two, three, four, five, or seven or more suction tubes 81.
[0122] 12, the suction tube moving device 86 can move the suction tube 81 along the second horizontal direction (in other words, the Y direction perpendicular to the X and Z directions). In the examples shown in FIGS. 11 and 12, the suction tube moving device 86 can move the suction tube 81 three-dimensionally. Alternatively, the suction tube moving device 86 may be able to move the suction tube 81 two-dimensionally (for example, the suction tube moving device 86 may be able to move the suction tube 81 only in a direction along a plane parallel to the XZ plane).
[0123] As shown in FIG. 13, the silkworm rearing system 1 may include a transport device 41 that transports the first rearing container C1 between the egg transfer device 80 and the first rearing container storage area AR1. In the example shown in FIG. 13, the transport device 41 is a transport device separate from the first rearing container transport device 40. The transport device 41 can transport the first rearing container C1, for example, along the vertical direction (in other words, the Z direction) and the first horizontal direction (for example, the X direction). The transport device 41 includes, for example, a conveyor, or a transport device equipped with a transfer device that transfers the first rearing container C1 to the shelf T1.
[0124] (Other components of the silkworm rearing system 1) With reference to FIG. 13, other components of the silkworm rearing system 1 will be described.
[0125] The silkworm rearing system 1 may include a monitoring computer 101. The monitoring computer 101 monitors the state of each device (10, 20, 30, 40, 41, 60, 70, 80, 92). When an abnormality exists in each device (10, 20, 30, 40, 41, 60, 70, 80, 92), the monitoring computer 101 notifies the operator of information identifying the abnormal device and information identifying the type of abnormality. In the above embodiment, an example in which the control device 30 controls each device (10, 20, 30, 40, 41, 60, 70, 80, 92) has been described. Alternatively, the monitoring computer 101 and the control device 30 may cooperate to control each device (10, 20, 30, 40, 41, 60, 70, 80, 92).
[0126] The silkworm rearing system 1 may include a cocoon recovery device 103. The cocoon recovery device 103 is a device that recovers cocoons from the second rearing container C2 (for example, a robot that recovers cocoons from the second rearing container C2).
[0127] The silkworm rearing system 1 may include a cleaning device 105 for cleaning the first rearing container C1 and / or the second rearing container C2. The cleaning device 105, for example, blows air onto the first rearing container C1 (or the second rearing container C2) to remove feces or residual food from the first rearing container C1 (or the second rearing container C2). The feces removed from the first rearing container C1 (or the second rearing container C2) may be collected for use as feed for other livestock or as an ingredient in medicine. When silkworms are reared in a sterile environment, the silkworm feces are also maintained in a sterile state. Therefore, the silkworm feces are suitable as feed for other livestock or as an ingredient in medicine.
[0128] In the above example, the cleaning device 105 is an air cleaning device that uses air. Alternatively or additionally, the cleaning device 105 may be a device that sprays water or a disinfectant onto the first rearing container C1 (or the second rearing container C2) to remove feces or remaining food from the first rearing container C1 (or the second rearing container C2).
[0129] The first rearing container C1 cleaned by the cleaning device 105 is reused for rearing silkworms in the first rearing container storage area AR1. The second rearing container C2 cleaned by the cleaning device 105 is reused for rearing silkworms in the second rearing container storage area AR2.
[0130] 13, the monitoring computer 101, the cocoon collecting device 103, and the cleaning device 105 are arranged in the first container 2A. Alternatively, at least one of the monitoring computer 101, the cocoon collecting device 103, and the cleaning device 105 may be arranged in the second container 2B. Alternatively, at least one of the monitoring computer 101, the cocoon collecting device 103, and the cleaning device 105 may be arranged outside the container 2.
[0131] (Silkworm rearing method) Next, an example of a silkworm rearing method according to the second embodiment will be described with reference to Figs.
[0132] In a first step ST1, a plurality of silkworms are reared in a first rearing container C1. The first step ST1 is a first silkworm rearing step.
[0133] In the first step ST1, first, in step ST101, silkworm food F is supplied to the first rearing container C1 (more specifically, the first area R1). Step ST101 is executed, for example, by using the above-mentioned food supplying device 60. More specifically, the first nozzle 621 ejects the food F into the first rearing container C1 (more specifically, the first area R1) while moving relative to the first rearing container C1 (more specifically, the first area R1).
[0134] In step ST102, a plurality of silkworm eggs E are transferred to the first rearing container C1. Step ST102 is performed, for example, by using the above-mentioned egg transfer device 80. More specifically, the transport device 41 transports the first rearing container C1 toward the egg transfer device 80, and then the egg transfer device 80 transfers the plurality of silkworm eggs E from the container C3 to the first rearing container C1. The number of silkworm eggs E placed in one first rearing container C1 is, for example, 10 to 1000, 30 to 500, or 50 to 300. It is preferable that the first rearing container C1 is sterilized in advance with a disinfectant or the like before the plurality of silkworm eggs E are transferred thereto. Sterilized silkworm eggs E are transferred to a sterilized first rearing container C1, and the first rearing container C1 is placed in a sterile atmosphere AT, thereby maintaining the sterile condition of the silkworms reared in the first rearing container C1.
[0135] Step ST102 may be performed before step ST101 or after step ST101. After steps ST101 and ST102 are performed, the first breeding container C1 is transported by the transport device 41 to the first breeding container storage area AR1.
[0136] Thereafter, the above-mentioned steps ST201 to ST205 are executed.
[0137] In step ST201, a plurality of silkworms A are raised in a first rearing container C1 (more specifically, in a first region R1). When a first partition member P1 is arranged in the first rearing container C1, a first rearing period during which the silkworms are reared in the first region R1 defined by the first partition member P1 is several days (e.g., 5 days).
[0138] After the first rearing period has elapsed, the first rearing container C1 is transported from the first rearing container storage area AR1 toward the feed supplying device 60. The transportation is performed by using, for example, the transport device 41 or the like.
[0139] In step ST202, silkworm food F is supplied to the first rearing container C1 (more specifically, the second area R2). Step ST202 is executed, for example, by using the above-mentioned food supplying device 60. More specifically, the second nozzle 622 ejects the food F into the first rearing container C1 (more specifically, the second area R2) while moving relative to the first rearing container C1 (more specifically, the second area R2).
[0140] In step ST203, the first partition member P1 is moved from the first position (partition position) to the second position (non-partition position). Step ST203 is performed, for example, by using the partition member moving device 70 described above.
[0141] After step ST203 is performed, the first rearing container C1 is transported to the first rearing container storage area AR1 by the transport device 41 or the like. After step ST202 is performed (in other words, after the second feeding), the second rearing period during which the silkworms are reared in the new first area Rn1 defined by the second partition member P2 is several days (e.g., 5 days).
[0142] After the second rearing period has elapsed, the first rearing container C1 is transported from the first rearing container storage area AR1 toward the feed supplying device 60. The transportation is performed by using, for example, the transport device 41 or the like.
[0143] In step ST204, silkworm food F is supplied to the first rearing container C1 (more specifically, the new second area Rn2). Step ST204 is executed, for example, by using the above-mentioned food supplying device 60. More specifically, the third nozzle 623 ejects the food F into the first rearing container C1 (more specifically, the second area Rn2) while moving relative to the first rearing container C1 (more specifically, the second area Rn2).
[0144] In step ST205, the second partition member P2 is moved from the first position (partition position) to the second position (non-partition position). Step ST205 is performed by using, for example, the above-mentioned partition member moving device .
[0145] After step ST205 is performed, the first rearing container C1 is transported to the first rearing container storage area AR1 by the transport device 41 or the like. After step ST204 is performed (in other words, after the third feeding), the third rearing period during which the silkworms are reared in the first rearing container C1 lasts for several days (e.g., five days).
[0146] In the above example, the feed F is supplied to one first rearing container C1 every few days, a total of three times. Alternatively, the number of times that the feed is supplied to one first rearing container C1 may be once, twice, or four or more times. When the feed F is supplied to the first rearing container C1 every few days, the silkworms A can grow by eating fresh feed. In contrast, when the feed F is supplied to the first rearing container C1 only once, there is a risk that the feed F will deteriorate due to drying, etc.
[0147] The total period during which the silkworms are reared in the first rearing container C1 (for example, the total of the first, second, and third rearing periods) is about 10 days (for example, 15 days). In this case, the silkworms grow from eggs to fourth-instar larvae in the first rearing container C1.
[0148] After the first step ST1 (first rearing step) is performed, in the second step ST2, a plurality of silkworms (e.g., a plurality of fourth instar larvae) in the first rearing container C1 are transferred to the second rearing container C2. The transfer is performed using a silkworm transfer device 10.
[0149] In the second step ST2, first, the first rearing container C1 and the second rearing container C2 are transported to the silkworm transfer area AR.
[0150] In the example shown in FIG. 13, as shown by the dashed line B1, the first rearing container C1 is transported from the first rearing container storage area AR1 to the silkworm transfer area AR. The transport of the first rearing container C1 to the silkworm transfer area AR may be performed using a plurality of transport devices including the first rearing container transport device 40. In the example shown in FIG. 13, the first rearing container storage area AR1 is located in the first container 2A, and the silkworm transfer area AR is located in the second container 2B. Therefore, the first rearing container C1 is transported from the first container 2A to the second container 2B. The transport of the first rearing container C1 from the first container 2A to the second container 2B is performed through the container connection part 95.
[0151] In the example shown in Fig. 13, the second rearing container C2 is transported from the second rearing container storage area AR2 to the silkworm transfer area AR, as shown by the dashed line B2. The transport of the second rearing container C2 to the silkworm transfer area AR may be performed using a plurality of transport devices including the second rearing container transport device 20. In the example shown in Fig. 13, the second rearing container transport device 20 is disposed in the second rearing container storage area AR2.
[0152] 13, the second breeding container storage area AR2 is located in the second container 2B, and the feed supplying device 60 is located in the first container 2A. In this case, in order to supply feed F to the second breeding container C2, the second breeding container C2 is transported from the second breeding container storage area AR2 in the second container 2B to the feed supplying device 60 in the first container 2A. This transport is performed using a plurality of transport devices including, for example, the second breeding container transport device 20 and the first breeding container transport device 40.
[0153] In the example shown in Fig. 13, the silkworm transfer area AR is located inside the second container 2B. Therefore, after the feed F is supplied to the rearing chamber SP of the second rearing container C2, the second rearing container C2 is transported from the first container 2A to the second container 2B (more specifically, the silkworm transfer area AR inside the second container 2B).
[0154] After the first rearing container C1 and the second rearing container C2 are transported to the silkworm transfer area AR, the silkworm transfer device 10 transfers the silkworms A from the first rearing container C1 to the rearing room of the second rearing container C2. It is preferable that the number of silkworms A transferred to each rearing room of the second rearing container C2 is one. By individually rearing the silkworms A, the stress of the silkworms A is reduced.
[0155] In the example shown in FIG. 14, a plurality of openings OP are formed at the first end Ca of the second rearing container C2. The plurality of openings OP correspond to the entrances of the plurality of rearing rooms SP, respectively. The silkworm transfer device 10 transfers the silkworms A to each rearing room SP through the openings OP. In the example shown in FIG. 14, the openings OP are formed at the side of the second rearing container C2. After the plurality of silkworms are accommodated in the second rearing container C2, the plurality of openings OP are covered by a cover member CL (see FIG. 1, if necessary). It is preferable that an air hole is formed in the cover member CL. The cover member CL is a member that changes its state between a first state in which the plurality of openings OP are open and a second state in which the plurality of openings OP are closed by the cover member CL. The first state means a state in which the silkworms can be inserted into the rearing room SP through the openings OP, and the second state means a state in which the silkworms cannot escape outside the rearing room SP through the openings OP. It is preferable that one cover member CL can close a plurality of openings OP simultaneously. In this case, the plurality of openings OP can be efficiently closed by the cover member CL.
[0156] Each rearing room SP has, for example, an elongated shape. More specifically, the depth of the rearing room SP is at least twice the height of the rearing room SP, and the depth of the rearing room SP is at least twice the width of the rearing room. When the rearing room SP has an elongated shape, a relatively small space is required for individually rearing a plurality of silkworms. In the example shown in FIG. 14, the length of each rearing room SP in the depth direction (in other words, the length in the direction from the first end Ca to the second end Cb of the second rearing container C2) is, for example, 20 cm or more, 30 cm or more, or 40 cm or more. It is preferable that the longitudinal direction of the rearing room SP is approximately parallel to the horizontal plane (in other words, it is preferable that the angle between the longitudinal direction of the rearing room SP and the horizontal plane is 20 degrees or less). In addition, it is preferable that the above-mentioned opening OP is formed at the longitudinal end of the rearing room SP.
[0157] In the example shown in FIG. 14, the second rearing container C2 includes a plurality of rearing chambers SP. The number of rearing chambers SP included in the second rearing container C2 is, for example, 10 to 1000, 30 to 500, or 50 to 300. A food support part PL for supporting food F is preferably disposed in each rearing chamber SP. The food support part PL is formed of, for example, a mesh-like member (in other words, a net-like member). In this case, silkworm droppings fall below the food support part PL through each opening of the mesh-like member. Therefore, the rearing environment for silkworms is less likely to deteriorate in the area above the food support part PL.
[0158] The food support part PL preferably extends from the first end part Ca of the second breeding container C2 (in other words, the first end part in the longitudinal direction of the second breeding container C2) toward the second end part Cb (in other words, the second end part in the longitudinal direction of the second breeding container C2). The food F arranged on the food support part PL preferably extends from the first end part Ca of the second breeding container C2 toward the second end part Cb.
[0159] In the example shown in FIG. 14, each of the breeding rooms SP is formed by an independent cylindrical container CY, and an assembly of the cylindrical containers CY constitutes at least a part of the second breeding container C2. The second breeding container C2 may be constituted by surrounding a plurality of cylindrical containers CY with a housing member H. In this case, a first sterile atmosphere is provided by the cylindrical container CY, a second sterile atmosphere is provided by the housing member H that accommodates the plurality of cylindrical containers CY, and a third sterile atmosphere is provided by the second breeding container storage area AR2 (or a container 2 such as the second container 2B) that accommodates the second breeding container C2. This more reliably maintains the sterile state in the breeding room SP. In addition, by setting the degree of sterility in stages, the sterile state in the breeding room SP can be efficiently achieved at low cost.
[0160] Alternatively, as shown in FIG. 15, each of the breeding rooms SP may be defined by a partition wall J disposed in a housing member H. In this case, a first sterile atmosphere is provided by the partition wall J, a second sterile atmosphere is provided by the housing member H housing the partition wall J, and a third sterile atmosphere is provided by the second breeding container storage area AR2 housing the second breeding container C2 (or a container 2 such as the second container 2B). This more reliably maintains the sterile state in the breeding room SP. Furthermore, by setting the degree of sterility in stages, the sterile state in the breeding room SP can be achieved efficiently and at low cost.
[0161] 14 and 15, the cross-sectional shape of the breeding room SP in a plane perpendicular to the longitudinal direction of the breeding room is a rectangle. Alternatively, the cross-sectional shape of the breeding room SP in a plane perpendicular to the longitudinal direction of the breeding room may be a hexagon, an octagon, or another polygonal shape. Still alternatively, the cross-sectional shape of the breeding room SP in a plane perpendicular to the longitudinal direction of the breeding room may be a circle.
[0162] In the example shown in FIG. 13, after a plurality of silkworms are transferred from the first rearing container C1 to the second rearing container C2, the second rearing container C2 is transported from the silkworm transfer area AR to the second rearing container storage area AR2. The transport is performed using the second rearing container transport device 20 or the like. In addition, after a plurality of silkworms are transferred from the first rearing container C1 to the second rearing container C2, the first rearing container C1 is transported to the cleaning device 105. After the first rearing container C1 is washed by the cleaning device 105, it is reused for rearing silkworms in a group.
[0163] In the third step ST3 (second rearing process), a plurality of silkworms are reared in the second rearing container C2. In the second silkworm rearing process, for example, each of the plurality of silkworms A is individually reared in an independent rearing room SP. In the second silkworm rearing process, each silkworm grows from a fourth instar larva to a fifth instar larva, and then the fifth instar larva spins a cocoon.
[0164] Before the fifth instar larvae make cocoons, the air conditioner 92 preferably supplies dry air to the first end Ca or the second end Cb of the second rearing container C2. Since the fifth instar larvae prefer dry air, the fifth instar larvae gather at the first end Ca or the second end Cb by supplying dry air to the first end Ca or the second end Cb of the second rearing container C2. In this case, it becomes easier to take out the cocoons from the first end Ca or the second end Cb (for example, it becomes easier for the cocoon collecting device 103, more specifically, the robot, to take out the cocoons from the first end Ca or the second end Cb).
[0165] After the fifth instar larvae make cocoons, the second rearing container C2 is transported from the second rearing container storage area AR2 to the cocoon recovery device 103. The transport is performed using a transport device such as the second rearing container transport device 20.
[0166] In the example shown in FIG. 13, the second rearing container storage area AR2 is located in the second container 2B, and the cocoon recovery device 103 is located in the first container 2A. Therefore, the second rearing container C2 is transported from the second container 2B to the first container 2A. In the example shown in FIG. 13, the transportation of the second rearing container C2 within the first container 2A is performed using the first rearing container transport device 40. After the cocoons are removed from the second rearing container C2, the second rearing container C2 is transported to the cleaning device 105. After being cleaned by the cleaning device 105, the second rearing container C2 is reused for individual rearing of silkworms.
[0167] In the silkworm rearing method of the second embodiment, rearing of relatively young silkworms and rearing of relatively old silkworms are performed separately, so that silkworms can be efficiently reared in a relatively small space. In addition, at least one of the following operations (preferably all of them) is automatically performed mechanically: transferring silkworms from the first rearing container C1 to the second rearing container C2, transporting the first rearing container C1 or the second rearing container C2, transferring silkworm eggs to the first rearing container C1, supplying food F to the first rearing container C1 or the second rearing container C2, washing the first rearing container C1 or the second rearing container C2, and recovering cocoons from the second rearing container C2. This improves the rearing efficiency of silkworms and makes it difficult for bacteria to be mixed into the rearing environment of silkworms.
[0168] In addition, when the first rearing container C1 and / or the second rearing container C2 are washed and reused, it is possible to repeatedly rear silkworms without refilling the first rearing container C1 and / or the second rearing container C2 from outside the sterile atmosphere to inside the sterile atmosphere (for example, inside the container 2). This reduces the risk of bacteria entering the sterile atmosphere AT. The cocoons collected by the cocoon collecting device 103 may be taken out through the door DR (see FIG. 4, if necessary) of the container 2 (more specifically, the first container 2A). Furthermore, the replenishment of the feed F and / or silkworm eggs E may be performed through the door DR of the container 2 (more specifically, the first container 2A). It is preferable that the door DR is a double door from the viewpoint of preventing bacteria from entering the container 2.
[0169] (Silkworm transfer device 10) An example of a silkworm transferring device 10 that can be employed in the silkworm rearing system 1 in the embodiment will be described with reference to FIG.
[0170] In the example shown in FIG. 17, the silkworm transfer device 10 has a holding member moving device 12 (more specifically, an arm unit) and a gripping unit 110. The holding member moving device 12 is, for example, a robot arm including one or more joints. The gripping unit 110 has a plurality of gripping pieces 111 including, for example, a first gripping piece 111a and a second gripping piece 111b. The number of gripping pieces 111 included in the gripping unit 110 may be two, or may be three or more.
[0171] The contact portion 112 of the gripping piece 111 that comes into contact with the silkworm is preferably made of an elastically deformable material (elastic material). The contact portion 112 is made of, for example, silicone rubber. By making the contact portion 112 out of an elastic material (for example, silicone rubber), it becomes possible to appropriately grip the silkworm, which changes shape and moves.
[0172] The gripping piece 111 may be, for example, a gripping piece having an internal space IS surrounded by an elastic material. In this case, it is possible to drive the gripping piece 111 by supplying a fluid such as air to the internal space IS. In the example shown in Fig. 17, each gripping piece 111 includes a fluid supply path PH that supplies a fluid to the internal space IS.
[0173] The present invention is not limited to the above-mentioned embodiments, and it is clear that each embodiment can be appropriately modified or changed within the scope of the technical idea of the present invention. In addition, various techniques used in each embodiment or modification can be applied to other embodiments or modifications as long as no technical contradiction occurs. Furthermore, any additional configuration in each embodiment or modification can be omitted as appropriate. For example, each component included in the second embodiment can also be adopted in the first embodiment.
[0174] In the second embodiment, an example has been described in which a plurality of silkworms are reared using a plurality of containers (2A, 2B). However, in the second embodiment, a plurality of silkworms may be reared using one container 2. Also, in the second embodiment, a plurality of silkworms may be reared in a sterile environment set up regardless of the container.
[0175] In the second embodiment, an example has been described in which the silkworm transfer device 10 and the second rearing container transport device 20 are disposed in the second container 2B. Alternatively, the silkworm transfer device 10 or the second rearing container transport device 20 may be disposed in the first container 2A. Further alternatively, the silkworm transfer device 10 or the second rearing container transport device 20 may be disposed in a sterile environment unrelated to the container.
[0176] In the second embodiment, an example has been described in which the first breeding container transport device 40, the food supply device 60, the partition member moving device 70, and the egg transfer device 80 are disposed in the first container 2A. Alternatively, the first breeding container transport device 40, the food supply device 60, the partition member moving device 70, or the egg transfer device 80 may be disposed in the second container 2B. Further alternatively, the first breeding container transport device 40, the food supply device 60, the partition member moving device 70, or the egg transfer device 80 may be disposed in a sterile environment unrelated to the container.
[0177] In the second embodiment, the silkworms transferred from the first rearing container C1 to the second rearing container C2 are 4th instar larvae. Alternatively, the silkworms transferred from the first rearing container C1 to the second rearing container C2 may be 5th instar larvae, for example. When 5th instar larvae silkworms (more specifically, silkworms immediately before making cocoons) are transferred to the second rearing container C2, placing food in the second rearing container C2 may be omitted. In this case, it is not necessary to transport the second rearing container C2 toward the food supplying device 60. When no food is placed in the second rearing container C2, the "food support part PL" in the above-mentioned embodiment is replaced with the "support part". The "support part" is a support part capable of supporting silkworms.
[0178] 14 and 15, an OP through which silkworms can pass is disposed at the first end Ca (first end surface) of the second rearing container C2. Additionally, an opening through which silkworms can pass may be disposed at the second end Cb (second end surface) of the second rearing container C2.
[0179] [Embodiment 3] An automatic sericulture system, an automatic sericulture method, a program, and a storage medium according to a third embodiment will be described with reference to Figs.
[0180] [Growth of silkworms] Eggs hatch in about 3 days at temperatures above 30 degrees Counting the days from hatching Larvae and young silkworms First molt 2nd instar 3rd instar 4th instar From the 3rd to 5th instars, they are raised in groups. It is possible to raise up to 1 million of them.
[0181] For example, on the 15th day, when the silkworms are less active before molting from the 3rd to 4th instar, a picking robot is used to remove the silkworms from the group rearing container and move them to individual rearing containers. Alternatively, they can be reared in individual rearing containers from the egg stage. Silkworms may be moved from the group rearing container to individual rearing containers at any stage: egg, young silkworm, 1st to 5th instar, or mature silkworm.
[0182] Since the individual rearing containers are made of SUS and are expensive to manufacture, it is desirable to use them as frequently as possible. To achieve this, it is advantageous to rear the silkworms in groups until they become ripe, and then move them to individual rearing containers once they have matured. For example, the silkworms can be reared in group rearing containers until they reach the 25th day of maturity, and then moved to individual rearing containers when they are ready to start spinning silk. In this case, it is possible to determine whether the silkworms are ready to start spinning silk by detecting the following characteristics: -Lots of poop and pee. Body color changes from white to yellowish transparent. Lift your head.
[0183] About 5th stage mature silkworms Continue feeding for 10 days Then pee, lots of feces, white to yellow (transparent) Starts spinning threads on the 25th day Cocoon, day 28, removed about 3 days after cocoon formation begins The number of days is a rough guide, so the time can be roughly determined, but the timing of removing the cocoons can be adjusted by sensing. Sensing can be done about once an hour. The silkworm is exposed to light and observed with a sensor. Once the cocoon is complete, the silkworm stops moving inside the cocoon. An X-ray camera or an infrared camera may also be used.
[0184] When collecting eggs, the moths are raised until they break out of the cocoons and emerge as adult silkworm moths. A single female lays about 200 eggs.
[0185] [About feed] Mulberry leaves are dried and powdered (weight is one-third of that of fresh leaves) The fineness is about 80μm to 100μm. Drying takes time The moisture content of leaves is 60% in winter and 70% in summer. 70%~60% → 30% Heat pump dryer 6 hours → 3% for 3 days 30% →3% Vacuum + Microwave + Stirring for 20 minutes Make a bavarois-like kamaboko-shaped block from the dried powder The softness varies depending on the ingredients and their ratio, ranging from a mayonnaise-like consistency to a udon-like hardness. Alternatively, the product may be dried from start to finish using a heat pump dryer. When the mixed feed is put into the hopper, it is squeezed out by the pump, and the feed of the desired thickness can be provided to the designated place in the rearing container. The thickness and the mixing ratio can be changed according to the growth of the silkworms. The feed mixing and thickness adjustment are also automated.
[0186] Dried mulberry leaf powder (sterilized) · Secondary feed Defatted soybeans Dried soybean pulp from the soy sauce and tofu manufacturing process (edible and sterilized). Amino acids and protein are necessary. Moisture (use sterilized or germ-free water.) Mix the above three ingredients together and form into a soft, bavarois-like shape.
[0187] ratio Mulberry powder 3 grams (10%) Sub-feed 6g Water 21g Total 30 grams High temperature drying → Nutrients are lost. Supplementary additives must be added. Low temperature drying: Nutrients are less likely to be lost, so supplementary additives may not be necessary. For example, the ingredient called human oxyria, which increases the appetite of 1st to 3rd instar silkworms, is not lost. - Drying in an oven (for processing the silkworms inside the cocoons) is at about 80°C. The heat pump method of drying is around 50 to 60 degrees Celsius. Drying using vacuum + microwave is around 40℃. Alternatively, drying and pulverization, such as freeze drying, may be performed.
[0188] Feed is automatically supplied to the group rearing container by a feed supplying means. The thickness and mixture ratio of the feed can be adjusted according to the growth of the silkworms. In the group rearing container, the position where the feed is supplied is changed according to the growth of the silkworms. For example, when replenishing the feed on the 5th day, feed with a predetermined mixture ratio and size (thickness) is supplied to a position adjacent to the position where the eggs and the first feed are supplied. When replenishing the feed on the 10th day, feed with a predetermined mixture ratio and size (thickness) is supplied to a position adjacent to the position of the feed placed on the 5th day. When replenishing the feed on the 15th day, feed with a predetermined mixture ratio and size (thickness) is supplied to a position adjacent to the position of the feed placed on the 10th day. In this way, by shifting the position where the feed is supplied, the position of the silkworms can be guided to the position where the feed is located, and feces can be prevented from accumulating only at the position of a specific feed.
[0189] [Silkworm transportation] Picking Robot Soft Robotics, Suction Cups and Hands Example 1) A third-instar silkworm, approximately 3cm long, is sucked up by a vacuum suction cup at the end of a robot arm. Example 2) Holding with a soft air-driven hand. Soft material made of adhesive silicone. Example 3) Hold with a soft air-powered hand and suck up with a vacuum cup. The hand that picks up the cocoons is air-driven and holds them softly. The hand that picks up the silkworms and the hand that picks up the cocoons can be automatically switched.
[0190] At the silkworm pick-up position 212, a rotating table is used, so that the silkworms can be picked up by a picking robot while rotating the group rearing container. For example, the position of the silkworms is determined by two-dimensional image recognition using a monocular camera. The position of the cocoon is also determined by two-dimensional image recognition using the monocular camera, and the cocoon is removed by a cocoon picking hand. One camera is installed at the silkworm pick position, and another camera is installed at the cocoon pick position. However, it is also possible to perform three-dimensional image recognition using a two-axis camera (stereo camera). At the position 213 for moving silkworms to individual rearing containers or removing cocoons from the individual rearing containers, the individual rearing containers can be raised and lowered by a lifter. The movement of silkworms to the individual rearing containers and the removal of cocoons from the individual rearing containers are performed at the same position 213.
[0191] Figure 26 is a photograph of the cameras. The cameras are installed above the picking robot, for example, one camera at the silkworm picking position and another camera at the cocoon picking position. Illumination means for illuminating the shooting range is installed near the cameras.
[0192] [Egg supply means] Egg sorting In water, healthy eggs sink and dead eggs float. Healthy eggs are picked up using a dropper, using a robot Eggs are placed into a V-groove shaped disinfectant tank. Normal eggs will sink to the bottom of the V-groove. The eggs that have sunk to the bottom are sucked up using suction means (multiple dropper-shaped suction means in a row) and placed in a designated location in the group rearing container. The eggs are then arranged in multiple rows, for example six rows. Food is also supplied in multiple rows parallel to the egg arrangement, between the rows of eggs. The disinfectant used may be, for example, Osban Liquid (registered trademark). Dilute the original solution to about 1%. Ozone water may also be used. Disinfect the surface of the eggs.
[0193] [An example of a sericulture system using containers] Although not particularly limited, the automatic silk-raising system of this embodiment can also be housed in two containers. Container No. 1 Work Space Container 2: Breeding room, A conveyor that connects the two It is capable of rearing around 20,000 silkworms. If the scale is expanded, it will be possible to raise silkworms in the millions.
[0194] Working with the first container Egg selection, preparation of group rearing containers, preparation of individual rearing containers Adding food Silkworm Pick-up Transfer from group to individual enclosures. Multiple picking robots can be used. For example, multiple picking robots can be placed around a circular or other rotating conveyor (on the inner or outer circumference) and use camera image recognition to pick up only the ripe silkworms.
[0195] Second Container Multiple breeding shelves for storing individual and group breeding containers 29 to 31 show the rearing shelf and the automatic rearing container storing means arranged in the second container. Figure 29 is a photograph of the rearing shelves. Figure 30 is a photograph of the rails of the automatic rearing container storage means. Figure 31 is a photograph of the automatic breeding container storage means. The automatic breeding container storage means is provided with a lifting means and a means for storing and removing the breeding containers from the breeding shelf.
[0196] [Germ-free rearing] Features Completely sterile Humidity 70% to prevent food from drying out 20~25℃ Silkworms prefer this temperature Sterile, no spoilage of food = healthy silkworms Disinfection of the outside of the eggs. The eggs are placed in a V-groove disinfectant tank and only those that sink to the bottom are removed. · Provide sterile feed. · The rearing environment should be sterilized or germ-free. The room should be clean and equipped with an air purifier that uses a HEPA filter. Dust particles of 1 micron size should be removed.
[0197] Egg Management Hatching occurs in about 3 days at temperatures above 30 degrees. When purchasing from a vendor, specify the expected hatching date. Variety and quantity
[0198] By mixing Clafen water with feed, the tensile strength of the thread can be increased by about 1.5 times.
[0199] [Breeding method] Feed every 5 days Eggs + food → (5 days later) Feeding → (5 days later) Feeding → (5 days later, 15 days in total, immobile period before molting from 3rd to 4th stage) 3rd stage silkworms, about 3cm in size, are transferred to a tube using a picking robot (a vacuum-drawn suction cup), the tube is filled with food, a generous 20g → (25th day) They start to spit out silk and make cocoons → (3 days later, 28th day in total) The cocoons are removed using a picking hand
[0200] [Cleaning process] The droppings are used as herbal medicine, and the feces fall through the gaps in the wire mesh and accumulate at the bottom. → Only the droppings are collected. The molted shells and leftover food remain on the wire mesh and can be separated. Group cages, individual cages and separators are cleaned after use. This cleaning can be automated, for example by automatic cleaning using a water stream in a cleaning tank.
[0201] Fully automated -Collecting collected cocoons Collection of collected feces -Collection of collected residues (leftover food, molting material) Feed supplementation Egg replenishment All of these steps can be automated, although any of them may be done manually. A fully automated sericulture system can be realized. The egg supplying means, feed supplying means, silkworm moving means, cocoon removal means, automatic rearing container storage means, and rearing container moving means are all automated. Without manual intervention, sterilization is easier and stress on the silkworms is reduced. In traditional sericulture, it was very difficult to align the timing of putting the silkworms in the sieve and the time when they would sprout. In this embodiment, the time when they would sprout is analyzed by sensing, and variable work can be performed according to the analysis results. Monitoring (sensors), data analysis and decision-making (using AI), variable work according to the analysis results (automation by robots). When the 3rd to 5th instars are transferred to individual rearing containers, there is no need to manage the emergence period. The time to remove the cocoons can be determined by the number of days or by sensing. When selecting and picking up only mature silkworms, since there are slow-growing silkworms even in the same group rearing container, it is advisable to provide a group rearing container stocker in the vicinity of the picking position where the group rearing containers can be temporarily stored so that the picking operation timing can be adjusted. By using IoT technology, it is possible to monitor the silkworms' growth and optimize the work schedule according to their growth. For example, the status of the silkworms or cocoons can be monitored with a camera. For example, monitoring can be done every hour.
[0202] [Individual breeding container] The breeding space is arranged in a matrix, for example 5 rows x 10 columns. One breeding space is divided into two rooms by a partition. To remove the cocoons, push the partition members halfway lengthwise, one at a time, on a workbench. For example, the tube is 5 columns and 10 rows, with a partition in the middle and a net to raise the bottom, and the droppings accumulate under the net. The middle partition is surrounded by a sponge, and by moving half of the partition, the droppings inside can be scraped out. The initial cleaning is completed at the same time as removing the cocoons. Removable lids (translucent) are provided on both sides.
[0203] [Collective breeding container] The group rearing container is a roughly rectangular container with a bottom, and a moisture supplying means is provided in the center to prevent drying. See the roughly rectangular container at the bottom center of Figure 22. The moisture supplying means can be a sponge soaked in moisture, or water can be placed directly in the container as the moisture supplying means. A removable lid (translucent) is provided on the top of the group rearing container.
[0204] [Partition material] FIG. 23 is a photograph of a partition member. The partition member 240 is inserted into the breeding space of the individual breeding container. The partition member 240 has a partition portion 241 and a flat portion 243. The partition portion 241 divides the breeding space into two spaces. The flat portion 243 serves as a floor for breeding silkworms or cocoons. The flat portion 243 has a plurality of holes, and the silkworm droppings fall through the holes and accumulate between the bottom of the breeding space and the lower portion of the flat portion 243. An elastic member 242 made of, for example, a sponge is provided around the partition portion 241. The elastic member 242 corresponds to the shape and dimensions of the inner wall of the breeding space. The flat portion 243 has protruding portions 246 on both ends thereof that are convex on the upper surface side.
[0205] FIG. 24 is a diagram showing a case where the partition member 240 is pushed out of the rearing space by the partition member moving means 220 by a distance of half the length of the partition member 240. When the partition member 240 is pushed out halfway from the rearing space in this way, the elastic member 242 is in sliding contact with the inner wall of the rearing space, so that the feces and the residue other than feces in the storage space can be separated and removed. FIG. 25 is a photograph of the time when the cocoon is removed from the individual rearing container. Since FIG. 25 is a reference photograph different from the actual installation position, it differs from the actual positional relationship. The position at which the cocoon is removed is a position where the partition member 240 is pushed out halfway from the rearing space, and the partition member storage part is in contact with the individual rearing container, and the protruding side of the partition member 240 is fitted into the partition member storage part. In this state, the feces are scraped out by the elastic member 242 and collected by the feces collection container. On the other hand, residues other than feces, such as uneaten food and molted skin, remain on the flat surface 243, so that feces and residues other than feces can be separated and removed.
[0206] In order to return the partition member 240 from the position shown in FIG. 24 back into the rearing space, the claws provided on the partition member moving means 220 are adapted to engage with the protrusions 246. The individual rearing containers are placed on a lifter, so their height can be adjusted. The individual rearing containers have, for example, 5 tiers and 10 rows, totaling 50 rearing spaces. Each tier has 10 rearing spaces, and the partition members 240 inserted into the 10 storage spaces on each tier can be moved simultaneously by the 10 arms of the partition member moving means 220. The claws provided on the partition member moving means 220 are engaged with and disengaged from the protrusions 246 by adjusting the height of the lifter. If the individual rearing containers are rotated 180 degrees, the partition member 240 can be pushed out of the rearing space by half from both sides of 212 from the opposite side, and the partition member 240 can be pushed out of the rearing space from the opposite side as well.
[0207] [Embodiment 4] In this embodiment, a method is described in which, unlike in the third embodiment, a picking robot is not used when transferring from a group breeding container to individual breeding.
[0208] From the second instar (about 20 mm), they are moved into a cage (multiple boxes of about 50 mm x 50 mm separated by dividers). In other words, they are moved from group rearing to individual rearing.
[0209] Example 1 Using a conical tool such as a funnel (funnel 310), the silkworms are placed one by one into the upper brood chamber container 300. If one silkworm cannot fit into each box 301, for example, if two silkworms fit into one box, or if an empty box occurs, a pick robot is used to move the silkworms so that each box contains one silkworm.
[0210] Cocoons can be harvested in about three days, making it possible to produce 120 cocoons per year. The number of days the rearing equipment needs to be used is reduced.
[0211] FIG. 33 shows a funnel 310A of a modified example. A first valve 311 is provided above the extraction port of the funnel 301A, a second valve 312 is provided below the extraction port, and a valve chamber 313 is provided between the first valve 311 and the second valve. When the first valve 311 is opened and, for example, one silkworm moves to the first valve chamber, the first valve 311 is immediately closed, so that one silkworm moves to the valve chamber 313. Next, when the second valve 312 is opened, one silkworm is extracted from the valve chamber from the funnel 310 to one basin 301. This allows one silkworm to be stored in each basin 301. If a sensor is provided in the valve chamber 313, it is possible to control the first valve 311 and the second valve 312 in response to detection of the silkworm by the sensor. This allows the silkworms to be moved one by one to the valve chamber 313, and the silkworms to be reliably extracted one by one from the funnel.
[0212] Example 2 An individual movement box 330, which is divided into multiple boxes 331, is placed on top of the group rearing container 320. The inside dimensions of the group rearing container 320 are approximately equal to the outside dimensions of the individual movement box 330. Since silkworms have the habit of climbing to the top and keeping their distance from other silkworms, one silkworm will enter each box of the box members by itself.
[0213] (Modification 2-1 of Example 2) Instead of the grid-shaped box members, for example, a plurality of wave-shaped partition members are stacked, that is, a wave-shaped individual moving box 333 provided with a plurality of wave-shaped boxes 333 is used. Since it is easier to manufacture the partition members by stacking them than to manufacture the box members, the device becomes less expensive. The partition members are not limited to wave shapes, and may be, for example, continuous rectangles.
[0214] (Modification 2-2 of Example 2) Instead of the lattice-shaped cage member, the silkworms can be raised using a wire mesh-type individual moving cage 336, for example, made by bending a wire mesh 335 into a continuous wave shape. Mature silkworms have the habit of making cocoons in three-dimensional places. By utilizing this habit of silkworms, the silkworms recognize the three-dimensional space between the wire meshes formed in the wire mesh-type individual moving cage 336 as a three-dimensional shape, and make their cocoons in this space.
[0215] (Modification 2-3 of Example 2) By utilizing the tendency of silkworms to gather where there is food, the silkworms are dispersed throughout the mass rearing container 320 by distributing paste-like food, and it becomes possible to induce the silkworms to move one by one to the container 331 when the individual movement container 330 is placed over the container.
[0216] Fig. 37A (left diagram) shows a case where small silkworms that have just hatched from eggs are raised in a first partition 321. Food 325 is dispersedly placed in the first partition 321. The silkworms gather around the dispersed food, and as a result, the silkworms can be dispersed and raised.
[0217] Fig. 37B (center diagram) is an explanatory diagram of a case where, when the silkworms grow large, the first partition 321 is removed and the silkworms are reared in the second partition 322. Feed is evenly distributed in the second partition, and the silkworms gather around this feed, so that the silkworms can be reared dispersedly within the second partition 322.
[0218] In Figure 37C (right), when the silkworms grow even larger, the second partition 322 is removed and the silkworms are raised in the entire group rearing container 320. Paste-like food is evenly distributed inside the group rearing container 320. The silkworms gather around the food, and as a result, the silkworms are distributed approximately evenly inside the group rearing container 320. When the silkworms become mature in this state, if an individual transfer box 330 is placed over the group rearing container 320, it becomes possible to guide the approximately evenly distributed mature silkworms one by one into the boxes 331.
[0219] Example 3 When rearing silkworms in the group rearing container 320, in addition to the silkworms, silkworm feces and residues such as leftover food accumulate in the group rearing container 320. In order to raise the silkworms to the upper brood chamber, it is necessary to take out only the mature silkworms, but if you try to take out the mature silkworms directly from the container, the residues will inevitably come out with them. Therefore, by using a vacuum suction nozzle with an output that allows the silkworms to stand in the group rearing container 320 by themselves, it is possible to suck out only the residues in the group rearing container 320 and take out only the mature silkworms together. If only the mature silkworms can be taken out, it is possible to throw the silkworms together into the funnel 310 of the embodiment in Figure 32. Furthermore, even if the funnel 310 is not used, since silkworms have the nature of keeping a distance from other silkworms, simply scattering the mature silkworms on the upper brood chamber container 300 will allow the silkworms to enter each box 301 one by one and make cocoons there.
