In this embodiment, the koji making device 5 is a box-shaped wooden box (koji lid) 2 which is a container for storing steamed rice, and a setting device 3 for setting steamed rice mixed with seed koji and a setting device. A large number of subsequent koji lids 2 are loaded and stacked, and before and after the koji lids 2 are moved up and down and transferred to rotate the koji lids 2 in the stacked state in order to give uniform koji making conditions such as temperature, humidity and CO ₂ concentration 2 Consists of circulation mechanisms 4 and 4 joined to a base, and a stirring device 6 for changing fermentation shapes as needed on the circulation mechanisms 4 and 4 and for homogenizing fermentation conditions in each koji lid 1. To be done. Hereinafter, each of these devices and mechanisms and their respective operations will be described in detail.

A. Koji-making room The peripheral wall and the ceiling are made of a non-water-containing and heat-insulating material so as to form an environment room in which the koji-making device 5 is movably accommodated in the koji-making room 1 and is isolated from the external environment, It is equipped with a function to purify the outside air with an air conditioner installed outdoors and to adjust the temperature, humidity and air volume through the hood, and oxygen concentration, carbon dioxide concentration, etc. as necessary. Furthermore, the koji making room 1 is connected to an external controller to measure and control the internal environment as described above, such as a thermometer, a hygrometer, and a concentration meter for sampling and measuring carbon dioxide (CO ₂ ). (Not shown) is attached.

B. Arrangement device In the arrangement device 3, a hopper 18 for putting steamed rice on the frame 16 is attached, and below the hopper 18, a carry-in line 19 composed of a belt conveyor for placing the koji lid 2 on standby is provided. It is installed in the direction. The carry-in line 19 is connected to a lower transfer line 27a described later. Further, the arranging device 3 is detachably attached to the circulation device 4.

On the koji lid 2, steamed rice mixed with a predetermined amount of koji is discharged from the discharge port 21 of the hopper 18 and is placed on the koji lid 2. At this time, the damper 22 is opened and closed to supply the steamed rice. The amount is set so that it is always constant. The amount of steamed rice supplied to the hopper 18 is determined by the amount of the steamed rice placed on the koji lid 2 and the total amount of steamed rice loaded in the circulation mechanism 4 (for example, 110 to 120 kg). In the arranging device 3, the steamed rice is arranged in a mountain shape as an initial shape, and in the koji lid 2 after the arranging, it is sent into the circulation mechanism 4 on the left side in FIG. As shown in the drawing, the shaving device 3 may be attached to each circulation mechanism 4. However, since it is sufficient that the steamed rice is swelled only once at the start of the koji making operation, the circulation devices 4 in front of and behind the sewage device 3 are not necessary. It is also possible to prepare one arranging device and move it back and forth in the koji making room 1 to arrang the respective circulation mechanisms 4 on the containers, which saves space. ..

C. Circulation Mechanism (a) Lower Transfer Line Below the frame 26 of the circulation mechanism 4, a lower part that is connected to or is connected to the conveyor of the carry-in line 19 as a transfer driving unit of the koji lid container 2 so as to be integrated therewith.

A large number of guide pulleys 33 that support the belt 28 and the koji lid 2 are axially supported at an appropriate pitch below the upper side of the belt 28.

(B) Ascending / descending line In the frame 26, there are a large number of stages (in the illustrated example, 11 stages each have at least one empty space for rotating the koji lid 2). An ascending line 36a and a descending line 36b are formed in which the koji lid 2 is stacked in parallel in the left and right two rows along guides 34a and 34b provided vertically in the frame.

Between the belts 28, 28 below the elevating lines 36a, 36b, the lowermost koji lid 2 is received from below, or lifted up and down is lifted up and down from an air cylinder equipped with two pistons inside a cylinder. Actuators 38a and 38b are installed facing upward.

The ascending line 36a is a mechanism for intermittently raising the koji lid 2 sent by the lower transfer line 27a step by step by the actuator 38a at regular time intervals, and the descending line 36b is an upper transfer line described later. When the koji lid 2 is transferred to the uppermost stage by 27b, it is a mechanism for lowering it one by one according to the ascending interval in the ascending line by operating the actuator 38b. In addition to the actuators 38a, 38b, stopper mechanisms 39, 39, 35 (described later) provided at the upper and lower positions before and after each line are interlocked for these operations.

(C) Structure of Koji Lid The koji lid 2 is made of, for example, a 500 × 700 × 120 (mm) box-shaped wooden tray. The trapezoidal or inverted trapezoidal notches 40a, 40b are formed through the lower notch 40a serving as a handle (handle) for normal carrying, and the two notches 40a, 40b are overlapped when the koji lid 2 is stacked. It can be combined and used as a ventilation window having a substantially hexagonal shape.

(D) Stopper Mechanism The lower stopper mechanism 39 is horizontally fixed to the front and rear positions of the lower ends of the elevating lines 36a and 36b on the frame 26 side, and is inserted into and removed from the notch 40a of the koji lid 2. The two hooks (not shown) are slidably attached to the front and rear, and the hook is appropriately inserted into and removed from the notch 40a of the koji lid 2 by a drive unit (not shown) including an air cylinder that is driven forward and backward. Then, support and release the koji lid 2 on the upper part.

The upper stopper mechanism 35 has a structure similar to that of the stopper mechanism described above, but is inserted into the notch 40a of the uppermost container 2 so that the upper stopper mechanism 35 can be moved left and right. It constitutes a part of 27a. Further, the stopper mechanisms 35 and 39 between the two circulation devices 4 and 4 are designed to engage and disengage the container 2 with a hook by a single air cylinder, and the upper stopper mechanism 35 is left and right. At the time of transfer, both upper and lower containers 2 of the circulation devices 4 and 4 are horizontally moved.

(E) Upper Transfer Line On the elevating lines 36a and 36b, the frame 26 is provided with an upper transfer line 27b for horizontally transferring the koji lid 2 at the uppermost position of each line from left to right. The feed line 27b includes a sprocket 57 pivotally supported on the front and rear ends of the left and right side surfaces of the frame 26, two chains 58 wound around the sprocket 57 in the left and right directions, a motor 56 for driving the sprockets 57 and the chains 58. It is equipped with a transfer drive consisting of. Both ends of the chains 58, 58 are connected to both ends of the above-mentioned slider 87 of the upper stopper mechanism 35, and the stopper mechanism 35 is horizontally moved in parallel with its driving. Then, with the koji lid 2 rising to the uppermost position on the ascending line 36a and the uppermost position of the descending line 36b being an empty space, the koji lid 2 is placed above the descending line 36b from above the ascending line 36a. It is slid horizontally while being supported by.

D. Stirring device The stirring device 6 changes the shape of the steamed rice put up by the putting device 3, and this change makes the entire koji in the koji lid 2 under uniform conditions according to the progress of the koji making 2. In order to ferment, it is carried out at every rotation or at several rotation intervals. The agitator 6 includes a bracket 63 protruding from the ascending line 36a, a swing arm 64 including front and rear parallel links that pivotally support a base end portion or a bending point of the bracket 63, and the swing arm 64. Radiating claw-shaped stirrer 67 with a motor 66 attached to the front and rear of the front end of the air cylinder 68, and an air cylinder 68 (elevation drive unit) attached to the side of the frame 26 so as to swing the right end of the swing arm 64 up and down. ) And. As shown in the figure, since the stirring section 67 of the stirrer 6 is at the right position on the ascending line 36a, it descends from the start of the rightward movement of the upper transfer line 27b to the end before the stirring of the steamed rice, or further. It only needs to reciprocate within the range of movement.

The stirrer 67 descends from above when the koji lid 2 starts transferring from the ascending line 36a to the descending line 36b and continues to rotate in reverse rotation alternately, and the peripheral wall stirs as the koji lid 2 is transferred. Before contacting the portion 67, it is swung upward by the cylinder 68 and stored in the standby position for the next stirring operation. By this operation, the koji in the koji lid 2 is stirred over the entire width, but the speed of the upper transfer line 27b may be changed or the shaking of the stirring section 67 may be repeated as necessary to obtain a desired heap shape. is there. The agitation and change of the filling shape are carried out through the rotation after the first filling and transshipment (rotation), and during the work such as middle work, sushi work, koji, etc. Since each work has a different growth stage of koji. In order to change heat dissipation, evaporation, etc., different agitation and height changes are made, and other environmental control is also adapted to each stage.

E. Arrangement and Setting of Koji Lid Next, the first setting device of the koji lid 2 in the circulation mechanism 4 will be described. First, the lowermost stage of the ascending line 36a and the uppermost stage and the lowermost stage of the descending line 36b are respectively vacant spaces. As described above, the koji lids are stacked and set on each line, and the koji lids are set under the hopper 18. At this time, the guide 34b on the right side of the ascending line 36a has a mechanism that can be opened and closed like a door, and the koji lid 2 can be put in and taken out with the guide 34b open. Further, the koji lids 2 inserted into the ascending line 36a and stacked can be reversely operated by the rotation operation described below to be sequentially reloaded to the descending line 36b.

Next, the damper 22 is opened by the drive unit 23 to discharge a predetermined amount of steamed rice into the koji lid 2 and arrange it in the initial shape, and the carrying-in line 19 and the lower transfer line 27b are used to set the lowermost stage of the ascending line 36a. The actuator 38a of the ascending line 36a pushes the koji lid 2 up one step to set it, and the actuator 38b of the descending line 36b lowers the koji lid on the descending line side to the second stage. While supporting the above, the uppermost transfer line 27b transfers the uppermost koji lid 2 of the ascending line 36a to the empty space at the uppermost step of the descending line 36b. The koji lid 2 lowered onto the belt 28 is transferred to the lower part of the hopper 18, and the same operation is repeated for the number of koji lids 2 to complete the automatic assembling work, and the rotation of the next koji lid 2 is completed. It shifts to the koji-making work accompanied by.

F. Rotation In order to perform the rotation operation from the state shown in FIG. 1, the uppermost and lowermost koji lids 2 of the elevating lines 36a and 36b are simultaneously horizontally moved by the vertical transfer lines 27a and 27b, respectively, and moved to other lines. .. In the ascending line 36a, first, the actuator 38a is slowly raised to support the load of all the koji lids 2 stacked on the ascending line 36a, and the lower hooks are pulled out from the lower part of the koji lid 2 to release the support.

Next, after the actuator 38a is raised to the upper limit position, the upper hook is inserted into the bottom of the uppermost koji lid 2, and the actuator 38a is slightly lowered to move the upper second and subsequent koji lids 2 to the actuator. 38a. Subsequently, the lower hook is inserted and the actuator 38a is slightly lowered to support all the koji lids 2 except the uppermost one on the lower hook, and the next koji lid 2 is fed to the empty space on the lowermost stage. Waiting for At this time, a slight transfer gap is formed between the uppermost koji lid 2 of the ascending line 36a and the lower koji lid 2 adjacent thereto, and the actuator 38a also serves as the next koji lid 2. Has moved to the lower limit position that does not hinder the entrance of the koji, and a slight transfer gap is formed between the next koji lid 2 and the second koji lid 2 that enter from the descending line 36 b. ..

On the other hand, in the descending line 36b, the lower space of the actuator 39b passes through and contacts the bottom surface of the second-stage koji lid 2 supported below the empty space and loads these loads. The actuator 38b is moved up to the upper limit position at high speed so that it is supported, and the upper and lower hooks are both pulled out to release the support. Then, after lowering the actuator 38b, the lower hook is inserted, then the actuator 38b is lowered to the lower limit position, and the lowermost koji lid 2 waits for the lower transfer line 27a to transfer it to the ascending line 36a side. ing. Even in the descending line 36b, when the koji lid is supported by the upper and lower hooks, the koji lid 2 at the uppermost stage and the koji lid 2 at the lowermost stage are slightly contacted with each other so that they are not in contact with each other. A transfer gap is formed.

G. Koji-Making Work When the finishing work and the subsequent koji-making work are completed from the setting of the mechanism 2 to the circulation mechanism 4 as described above, the final stirring and cooling (cooling) of steamed rice is performed as the koji-making preparation work. After the koji is completed, the koji lid 2 is taken out of the koji making chamber 1. At this time, the koji lid 2 is taken out sequentially from the circulation mechanism 4 and carried out through the passage 9 and the entrance / exit 8 in the koji making chamber 1. .. Further, the removal from the circulation mechanism 4 is performed by opening the door-shaped guide 34b and extracting it from the upper part to the lateral side in the order, and when a certain amount is extracted, the rotation operation described above is performed to make the koji lid 2 of the descending line 36b. Are sequentially moved to the side of the ascending line 36a to complete all the removal.

H. Connection of the open end of the exhaust pipe As described above, the koji-making device is driven by the air cylinders except for the motor-driven part of the drive part. Including the cylinder, at least 17 air cylinders were used, and the exhaust air from these cylinder drives was discharged directly into the koji making room, which was also a cause of noise in the koji making room. Therefore, according to the present invention, as shown in FIGS. 2 and 3, the above-mentioned cylinders are stored in relay boxes 7 and 8 attached to the front and rear circulation devices 4 (which accommodates terminal blocks for electric wiring, solenoids, etc.). The air piping is open.

FIG. 3 shows the relay boxes 7 and (8) in which, for example, the ends of the pipes 10 a and 10 b of the air cylinder 68 of the agitator 6 are opened. Inside the relay box 7, the solenoid valve 11 and terminals are provided. The table 12 and the like are accommodated therein, and the electric wiring 13 is introduced and connected. Further, the pipe 10c of the compressor 14 is also piped in the relay box via the filter regulator 15. With the above configuration, the exhaust air from various air cylinders is always exhausted into the relay box 7, (8), which not only has the effect of silencing the exhaust noise in the koji making room, but also the internal exhaust heat and the box inside the high humidity environment. It is effective in dehumidifying and cooling.

[0028]

[Effect of the device]

 The present invention is configured as described above, and since the exhaust pipe of the pneumatic equipment is connected and opened in the relay box of the electric wiring, the hot and humid air in the environment room is removed from the relay box each time exhaust is performed. As a result of being ventilated to air with low humidity, the adverse effects of the high humidity atmosphere on the terminals in the relay box and electrical equipment are prevented, and the noise from air exhaust in the environmental room is also silenced by the relay box. This has the advantage of reducing the need for special muffling equipment.
