[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a suitable administration agent administration device for silkworms, which is used when administering an administration agent to silkworm larvae.

[0002]

[Prior art]

 Conventionally, as a method of coloring a silk thread, a method of directly dyeing the silk thread and a coloring method of causing a colored thread to be discharged from the silkworm larva by a pigment absorbed by the silkworm larva itself are known. In this coloring method, the pigment is absorbed into the body from the skin and digestive system of the silkworm larva by feeding the silkworm larva with a feed containing the pigment or immersing the silkworm larva in a pigment solution containing the pigment. , To make colored cocoons.

[0003]

[Problems to be solved by the device]

 However, such a conventional coloring method has the following problems.

First, as shown in FIG. 3, usually, the thread S exhaled by the silkworm larva is one in which the inner fibroin Si is covered with sericin So, but in the conventional method, sericin So is Although colored, fibroin Si is not sufficiently colored. Therefore, although it can be used for crafts such as a fan that directly uses the spited yarn S, it cannot be used for industrial applications in which fibroin Si depleted of sericin So is used as a silk yarn, and its use is extremely limited. It

Secondly, the method of immersing the silkworm larvae in the dye solution imposes an unreasonable burden on the silkworm larvae, which may weaken or kill the silkworms, and a work process for coloring. Becomes complicated, resulting in higher cost and more man-hours.

The present invention solves the problems existing in such conventional techniques. The colored yarn is spit out without imposing an excessive burden on the silkworm larvae, and the cost and man-hours for the coloring work are reduced. It is an object of the present invention to provide a device for administering a silkworm, which is capable of reducing the amount of use and dramatically expanding the use of colored threads emitted by silkworm larvae.

[0007]

[Means for Solving the Problems]

 A silkworm administration agent administration device 1 according to the present invention stores a silkworm larva A, for example, a silkworm accommodation chamber 2 also serving as a silkworm breeding chamber 2a, and a liquid administration agent such as a dye solution La or a drug solution Lb. It is characterized in that it comprises an administration agent fine particle generator 3 for converting the fine particles M and supplying the fine particles M to the silkworm storage chamber 2.

[0008]

[Action]

 According to the silkworm administration agent administration device 1 of the present invention, first, the liquid administration agent such as the dye solution La or the drug solution Lb is converted into the fine particles M by the administration agent fine particle generator 3. It is supplied to the silkworm housing chamber 2.

On the other hand, the silkworm storage chamber 2 also serves as, for example, a silkworm breeding chamber 2a, and since the silkworm larvae A are stored in the silkworm storage chamber 2, the fine particles M are generated by the respiration of the silkworm larvae A. It is sucked into the pneumostoma from the hilum and is also taken up by the silk gland. As a result, when the dye solution La is used as the liquid administration agent, the dye solution La is efficiently absorbed into the body of the silkworm larva A, and the colored thread from the silkworm larva A to fibroin can be spit out. .

Therefore, the colored thread exhaled from the silkworm larva A can be used for industrial purposes, and its application is expanded. In addition, the silkworm larva A is not overloaded, and automation is possible, and the coloring work is simplified.

【Example】

 Next, preferred embodiments according to the present invention will be described in detail with reference to the drawings.

First, the configuration of the silkworm administration agent administration device 1 according to the present embodiment will be described with reference to FIG.

In FIG. 1, reference numeral 2 a is a silkworm rearing room in which the silkworm larva A is stored, and this silkworm rearing room 2 a also serves as the silkworm storage chamber 2. The silkworm larva A housed is in the 4th to 5th stage.

On the other hand, 3 is a dosage agent fine particle generator. In the administration agent fine particle generator 3, 11 is a mist chamber. The mist chamber 11 includes, for example, a pair of rotating plates that are rotated by a motor, and introduces the dye solution La in the dye solution tank 12 into the gap between the rotating plates so that the dye solution is scattered by centrifugal force. It has a function of making the particles fine by converting the dye solution La into fine particles (ultrafine particles) M of 0.3 μm or less. The dye solution La is a solution in which a dye or a colorable vitamin agent or the like is dissolved, and the dye solution La supplied from the dye solution supply unit 13 is stored in the dye solution tank 12.

Further, the discharge side of the mist chamber 11 is connected to the inflow side of the water / water separation chamber 14, and the outflow side of the water / water separation chamber 14 is connected to the silkworm through the heating unit 15 and the supply duct 16. It is connected to the upper part of the breeding room 2a. In this case, the air / water separation chamber 14 has a large number of baffles inside, and has a function of collecting large particles in the fine particles M and returning them to the dye solution tank 12 by the baffles. Further, the heating unit 15 has a function of heating the fine particles M so as not to lower the temperature in the silkworm rearing room 2a.

On the other hand, the return side of the mist chamber 11 is connected to the lower part of the silkworm rearing room 2 a via a fan 17 and a return duct 18.

Reference numeral 19 is a cooler for adjusting the amount of solution contained in the air in the mist chamber 11, 20 is a boiler for heating the heating unit 15, and 21 is a device for preventing dust and the like from entering from the outside. Therefore, it is an outside air intake hole that prevents negative pressure in the silkworm rearing room 2a.

Next, the operation of the silkworm administration agent administration device 1 according to the present embodiment will be described with reference to FIGS. 1 and 2.

First, the dye solution La in the dye solution tank 12 is discharged from the mist chamber 11 to 0. It is converted into fine particles M of 3 μm or less. The fine particles M are sent to the air-water separation chamber 14 by the fan 16, and the relatively large particles in the fine particles M are collected in the dye solution tank 12. Further, the fine particles M that have passed through the air / water separation chamber 14 are further supplied to the silkworm rearing room 2a through the heating unit 15 and the supply duct 16.

On the other hand, since the silkworm larva A of the 4th to 5th stage shown in FIG. 2 is housed in the silkworm rearing room 2a, the fine particles M are transferred from the sacrum B to the lungs by respiration of the silkworm larva A. It is sucked into the pores and further taken up by the silk gland. Therefore, the dye solution La is efficiently absorbed into the body of the silkworm larva A. As a result, thread colored from silkworm larva A to fibroin is spit out.

Although a part of the fine particles M is inhaled by the silkworm larva A, the remaining fine particles M adsorb dust and the like in the silkworm rearing room 2 a and pass through the return duct 18. It is collected in the dye solution tank 12. Therefore, the dye solution La in the dye solution tank 12 is automatically supplied / drained according to the degree of contamination or a timer.

By the way, in the above-mentioned embodiment, the coloring device is illustrated, and the case where the dye solution La is stored in the dye solution supply unit 13 and the dye solution La is stored in the dye solution tank 12 has been described. Instead of La, a liquid medicine Lb such as a juvenile hormone is contained in the dye solution tank 12, and the liquid medicine Lb is stored in the dye solution tank 12, so that it can be used as a liquid medicine administration device. As a result, since it is not necessary to administer the drug solution using a syringe or the like, the drug solution can be administered without damaging the silkworm larva A.

Although the embodiments have been described above, the present invention is not limited to such embodiments. For example, the administration agent fine particle generator may generate fine particles based on a principle other than the example. In addition, the detailed configuration and method may be arbitrarily changed without departing from the scope of the present invention.

[0024]

[Effect of device]

 As described above, the silkworm administration agent administration apparatus according to the present invention converts the silkworm storage chamber containing the silkworm larvae and the liquid administration agent to be administered to the silkworm larvae into fine particles, and stores the fine particles in the silkworm storage. Since it is equipped with a fine particle generator for administration agent to be supplied to the chamber, the following remarkable effects are achieved.

The colored thread can be discharged without imposing an excessive burden on the silkworm larvae, and the coloring work can be simplified to reduce the cost and the number of steps.

Since it is possible to sufficiently color fibroin, the use of the colored yarn can be dramatically expanded such that it can be used for industrial purposes.
