It is an IVb-IVb arrow top view of a).

  First, an outline of the seed disinfection facility 1 will be described with reference to FIGS. 1 and 2.

  The seed disinfection equipment 1 includes a first hot tub 2 and a second hot tub 3 that are open upward substantially box-shaped in which hot water is stored, a cold tub 4 that is generally open upward in which cold water is stored, a carry-in conveyor 6 and The transfer unit 5 including the carry-out conveyor 7 is sequentially arranged in the clockwise direction in the plan view as four working units partitioned substantially in a cross shape in the plan view (see FIG. 1).

  The seed disinfection facility 1 is provided with a traveling crane means 9 for carrying a bowl-shaped container 10 (details will be described later) over the four working units. In this traveling crane means 9, the four bowl-shaped containers 10 arranged for the respective working parts are located at substantially the same radius from the center of the cross shape, and the positions of the working parts in plan view. The container is configured to be moved up and down all at once with respect to each working unit while being suspended by the working unit, and to circulate in a certain direction around the cross-shaped central portion at the raised position. .

  The container 10 in which the bag S filled with the seed pod is accommodated is formed in a bowl shape having an upper surface opening by a metal pipe or a bar. A handle 10 a such as a wire for hanging or a rope is attached to the container 10.

  Although not shown, the first and second hot tubs 2 and 3 include a water supply pipe communicating with a water supply source such as a water tank and a hot water supply pipe communicating with a hot water (steam) generation source such as a boiler. Communication connection is established. Inside each of the hot tubs 2 and 3, a net-like frame that divides the inside of each of the hot tubs 2 and 3 up and down is stretched. That is, the inside of each hot tub 2 and 3 has a double bottom with a mesh frame. A container 10 is placed on the mesh frame. A horizontally long diffusion pipe that communicates with the hot water supply pipe is disposed on the bottom side of the mesh frame. A plurality of nozzles for warm water diffusion are formed in the diffusion tube so as to open upward.

  Moreover, in the 1st and 2nd hot tubs 2 and 3, the temperature sensor for detecting the water temperature of the hot water stored inside is provided. In the embodiment, the water temperature in each of the hot tubs 2 and 3 is automatically adjusted by adjusting the opening / closing degree of a water injection valve provided in the middle of the hot water supply pipe with an electromagnetic solenoid or the like based on the detection value of the temperature sensor. It is configured to be adjustable to.

  Furthermore, a circulation pump for stirring the hot water inside is connected to each of the hot tubs 2 and 3. The suction port and the discharge port of the circulation pump are opened in the hot tub at different height positions. Thus, when the circulation pump is driven, the hot water in each of the hot tubs 2 and 3 is forced to circulate so that the upper layer and the lower layer are interchanged, and the water temperature is uniform in each part of the hot tubs 2 and 3. It becomes.

  A drain pipe for discharging hot water inside the tank to the outside of the tank is connected to the lower portions of the side surfaces of the first and second hot tubs 2 and 3. An overflow pipe is connected to the upper side of each hot tub 2, 3. The hot water that has exceeded the upper limit water level of each of the hot tubs 2 and 3 due to the immersion of the container 10 containing the bag S is discharged outside the hot tubs 2 and 3 through the overflow pipe. Therefore, even if the container 10 containing the bag S is immersed in the hot water in each of the hot tubs 2 and 3, the water level in each of the hot tubs 2 and 3 is maintained below the height of the overflow pipe. The overflow pipe is connected to the downstream side of the discharge valve provided in the middle of the discharge pipe.

  The structure of the cold tub 4 is basically the same as that of the hot tubs 2 and 3. However, the diffusion pipe in each cold tub 4 supplies cold water from the water supply pipe into the cold tub 4.

  In the transfer part 5, the carrying-in conveyor 6 and the carrying-out conveyor 7 which consist of roller conveyors etc. are arrange | positioned so that it may cross | intersect L shape by planar view.

  Next, the configuration of the first embodiment of the traveling crane means 9 will be described with reference to FIGS. 1 and 2.

  The traveling crane means 9 includes a disk-like support 11 in a plan view supported so as to be horizontally rotatable above all (four) working units, a driving means 12 for driving the support 11 to rotate horizontally, and a support Elevating means 13 mounted on the body 11 and elevating and lowering each container 10 detachably is provided. More specifically, the shaft 15 attached to the center of rotation of the disk-like support 11 can be horizontally rotated via a bearing 16 on the main frame 14 fixed above the four working parts. Suspend. The outer periphery of the support 11 is formed on the gear portion 17. On the other hand, a drive motor 19 as the drive means 12 is fixed to the main frame 14. A drive shaft 19 a of the drive motor 19 protrudes downward, and a pinion gear 20 is attached to the drive shaft 19 a, and the pinion gear 20 meshes with the gear portion 17.

  The axis 15 of the support 11 is substantially the same vertical as the cross-shaped central part that defines the first and second hot tubs 2 and 3, the cold tub 4 and the transfer part 5, which are the four working parts. It is arranged on the line. Four telescopic cylinders 21 such as a telescopic type as the elevating means 13 are the lower surface of the support 11, and the base end is fixed and suspended at the position of the radius R1 from the axis of the shaft 15 (see FIG. 1 and FIG. 1). (See FIG. 2). The radius R1 allows the container 10 to be located at a substantially central position in plan view of the first and second hot tubs 2 and 3, the cold tub 4, and the transfer unit 5. In addition, it is desirable to connect the air cylinder 21 part or the piston rod 21a with the connecting member 23 in the horizontal direction so that the vertical postures of the four air cylinders 21 do not shift.

  Each air cylinder 21 is of a type that is driven up and down by double action, and a hook 22 for suspending the handle 10 a of the container 10 is provided at the lower end of the piston rod 21 a of each air cylinder 21. The four air cylinders 21 are controlled by control means (not shown) that the piston rods 21 a expand and contract all at once and the intermittent rotation of the drive motor 19.

  With the above configuration, the operator located in the transfer unit 5 operates the four air cylinders 21 at the same time to lower each piston rod 21a. Next, the container 10 containing the bag S filled with unprocessed seeds placed on the carry-in conveyor 6 is suspended (locked) on the hook 22 of the piston rod 21a of the one air cylinder 21 positioned thereon. . Next, the four air cylinders 21 are operated simultaneously to raise the piston rod 21a, and the lower surface of the container 10 is raised to a position higher than the upper end edge of the first hot tub 2 (see the two-dot chain line state in FIG. 2). . In this state, the drive motor 19 is driven to rotate the support 11 horizontally by 90 degrees clockwise in FIG. Thereby, while the container 10 is located above the approximate center position of the first hot tub 2 in plan view, the right air cylinder 21 where the container 10 is not suspended is approximately at the center position of the transfer unit 5. I come to.

  Next, the four air cylinders 21 are simultaneously operated to lower the piston rod 21a, so that one container 10 is immersed in the first hot tub 2. At this time, since the piston rod 21a of the air cylinder 21 located at the transfer portion 5 is also lowered, the container 10 containing the next unprocessed seed candy packed in the hook 22 is locked. By setting the time for immersing the container 10 in the first hot tub 2 to T1 time (for example, 5 minutes) in advance and storing it, the control means allows the piston rods of the four air cylinders 21 for the T1 time. The lowering state of 21a is maintained and then raised, and then the support 11 is controlled to rotate horizontally by 90 degrees. In addition, in addition to the raising / lowering of the piston rod 21a, the total required time T2 for turning the support 11 90 degrees is usually set shorter than the T1 time.

  As described above, the unprocessed seeds are packed by executing the processing cycle of raising the piston rod 21a → rotating the support 1 → lowering the piston rod 21a → maintaining the state at the lowered position for only the T1 time. The container 10 containing the bag S is first immersed in the first hot tub 2 for T1 hours, then immersed again in the second hot tub 3 for T1 hours, and then immersed in the cold tub 4 for T1 hours. Then, a circulation (circulation) route of returning to the transfer unit 5 is followed. When the container 10 after cooling pulled up from the cold tub 4 moves to the transfer part 5, draining can be performed automatically.

  As described above, the seeds in each container 10 can receive a cooling action for T1 hours after being subjected to a disinfection action by a warm bath for 2 × T1 hours. During the T1 time, the disinfected container 10 and the unprocessed container 10 may be replaced with the hook 22 of the piston rod 21a at the position by the transfer unit 5. In this way, disinfection of seed potatoes can be performed efficiently (time can be shortened). In addition, since the four air cylinders 21 are moved up and down all at once and the mode of controlling the rotation of the support 11 is a very simple cycle, the control means can be simplified. Furthermore, since the four working parts can be arranged together in a cross-section partitioned in a plan view, the seed disinfection equipment 1 becomes extremely compact, and there is a remarkable effect that the required area of the facility can be reduced. Further, the replacement work of the container 10 in the transfer unit 5 can be performed by one operator, which has the effect of reducing the number of workers and the effect that the number of replacement containers 10 (the number of spares) can be reduced.

  FIG. 3A and FIG. 3B show the configuration of the traveling crane means 24 of the second embodiment. In this embodiment, similarly to the first embodiment, the first hot tub 2 and the second hot tub 3, the cold tub 4, the transfer section 5 including the carry-in conveyor 6 and the carry-out conveyor 7 are flat. As the four working sections partitioned substantially in a cross shape when viewed, they are sequentially arranged clockwise in a plan view.

  The traveling crane means 24 includes a disk-like support body 25 having hook-like suspension supports 26 (four) for detachably supporting the containers 10 above the four working units, and a support body 25. And a lifting / lowering drive means 27 capable of being driven to rotate horizontally.

  The main frame 28 arranged above the four working parts has an air cylinder 29 as a part of the components of the lifting and rotating drive means 27 above the center position of the cross in plan view that divides the working parts. A midway portion is suspended and supported so as to be horizontally rotatable through a bearing 30 capable of receiving a radial load and a thrust load at the same time. A piston rod 29a of the air cylinder 29 protrudes downward from the main frame 28, and a radial center portion of a disk-like support body 25 is attached and supported at the lower end portion of the piston rod 29a, and the support body 25 is held horizontally. . A driven gear 31 is fixed to the upper end of the air cylinder 29. A pinion gear 33 is fixed to a drive shaft of a drive motor 32 (a part of the components of the lift / rotation drive means 27) fixed to the upper surface of the main frame 28, and the pinion gear 33 and the driven gear 31 mesh with each other. Yes.

  Further, a sliding contact member 34 made of a synthetic resin having a small friction coefficient is attached and fixed to the outer periphery of the disk-like support body 25, and on the other hand, a plurality of rod-like members protruding downward from the main frame 28 (in the embodiment, Three slider members 35 are in sliding contact with the sliding contact member 34, respectively. Note that a plurality of (three in the embodiment) slider members 35 are connected and fixed by ring-shaped connecting members 36 so as not to swing.

  As in the first embodiment, the four hook-shaped suspension supports 26 are suspended from the lower surface of the support body 25 with their proximal ends fixed to a position of a radius R1 from the axis of the air cylinder 29. (See FIG. 3B). The radius R1 allows the container 10 to be located at a substantially central position in plan view of the first and second hot tubs 2 and 3, the cold tub 4, and the transfer unit 5.

  The air cylinder 29 is of a type that is driven up and down by double action, and the up and down drive of the air cylinder 21 and the intermittent rotation drive of the drive motor 32 are controlled by control means (not shown).

  With the above-described configuration, in order to perform disinfection of seed potatoes, an operator (one person) located in the transfer unit 5 operates the one air cylinder 29 and lowers the piston rod 29a, thereby supporting Together with the body 25, the four hook-like suspension bodies 26 also descend. Next, the container 10 containing the bag S filled with unprocessed seeds placed on the carry-in conveyor 6 is suspended (locked) to one suspension support 26 positioned thereon. Next, the one air cylinder 29 is operated to raise the piston rod 29a, and the lower surface of the container 10 is raised to a position higher than the upper end edge of the first hot tub 2 (see the two-dot chain line state in FIG. 3A). ). In this state, the drive motor 32 is driven to rotate the support 11 together with the air cylinder 29 horizontally by 90 degrees clockwise in FIG. As a result, the container 10 is positioned above a substantially central position in plan view of the first hot tub 2, and the right suspension support 26, in which the container 10 is not suspended, is approximately at the center of the transfer unit 5. Come in position.

  Next, when the one air cylinder 29 is operated to lower the piston rod 29a, one support 25 and four suspension supports 26 are lowered, and one container 10 is immersed in the first hot tub 2. Let At this time, since the suspension support body 26 located in the transfer part 5 is also lowered, the container 10 containing the bag S filled with the next unprocessed seed cake is locked to the suspension support body 26. By setting the time for immersing the container 10 in the first hot tub 2 to T1 time (for example, 5 minutes) in advance and storing it, the control means lowers the four suspension supports 26 for the T1 time. Then, the air cylinder 29 is rotated by 90 degrees in a predetermined direction (clockwise in FIG. 3B), and the support 11 is horizontally rotated. To control. Note that the total required time T2 for one turn for turning the air cylinder 29 in addition to the raising and lowering of the piston rod 29a is normally set shorter than the T1 time.

  As described above, the seeds in each container 10 can receive a cooling action for T1 hours after being subjected to a disinfection action by a warm bath for 2 × T1 hours. During the T1 time, the disinfected container 10 and the unprocessed container 10 may be replaced with the suspension support body 26 at the position by the transfer unit 5. In this way, disinfection of seed potatoes can be performed efficiently (time can be shortened). In addition, since the control mode of operating one air cylinder 29 up and down and intermittently rotating the air cylinder 29 (support 25) is a very simple cycle, the control means can be simplified. . Furthermore, since the four working parts can be arranged together in a cross-section partitioned in a plan view, the seed disinfection equipment 1 becomes extremely compact, and there is a remarkable effect that the required area of the facility can be reduced. Further, the replacement work of the container 10 in the transfer unit 5 can be performed by one operator, which has the effect of reducing the number of workers and the effect that the number of replacement containers 10 (the number of spares) can be reduced.

  4 (a) and 4 (b) show the configuration of the traveling crane means 40 of the third embodiment. In this embodiment, similarly to the first embodiment, the first hot tub 2 and the second hot tub 3, the cold tub 4, the transfer section 5 including the carry-in conveyor 6 and the carry-out conveyor 7 are flat. As the four working sections partitioned substantially in a cross shape when viewed, they are sequentially arranged clockwise in a plan view.

  The traveling crane means 40 is a non-circular cylindrical support with a bottom plate 41a provided with hook-like suspension supports 42 (four) for detachably supporting the containers 10 above the four working parts. The body 41, the raising / lowering means 43 which raises / lowers the support body 41, and the rotation drive means 44 which horizontally drives the support body 41 are provided.

  In the embodiment, the upper end portion of the air cylinder 46 as the elevating means 43 is hung on the main frame 45 disposed above the four working portions above the center position of the cross in plan view that divides the working portions. It is fixed. The piston rod 46a of the air cylinder 46 protrudes downward from the upper and lower through holes 47a of the subframe 47 fixed below the main frame 45, and the radius center portion of the bottom plate 41a of the support body 41 is located at the lower end of the piston rod 46a. A sliding contact member 49 made of a synthetic resin having a small friction coefficient and supported on the outer surface of the vertical cylinder 41b in the support body 41 is slidably in contact with the upper and lower through holes 47a. A horizontal rotating body 50 is supported on the upper surface side of the subframe 47 via a thrust bearing 51, and the noncircular outer surface of the vertical cylinder 41 b in the support body 41 with respect to the inner diameter portion of the horizontal rotating body 50. A plurality of sliding keys 52 fixed in the vertical direction are fitted so as to be movable in the vertical direction (see FIGS. 4A and 4B). A ring gear 53 is provided on the circular outer surface of the horizontal rotating body 50, and the pinion gear 55 of the drive motor 54 fixed to the upper side of the subframe 47 and the ring gear 53 are engaged with each other. Accordingly, the horizontal rotating body 50 and thus the support body 41 can be horizontally rotated intermittently by the intermittent rotation of the drive motor 54 in a certain direction.

  Similar to the first embodiment, the four hook-shaped suspension supports 42 are supported on the bottom surface of the support body 41 with their base ends fixed at a position of a radius R1 from the axis of the air cylinder 43. (See FIG. 4B). The radius R1 allows the container 10 to be located at a substantially central position in plan view of the first and second hot tubs 2 and 3, the cold tub 4, and the transfer unit 5.

  With the above-described configuration, in order to perform disinfection of seed potatoes, an operator (one person) located in the transfer unit 5 operates the one air cylinder 43 and lowers the piston rod 43a to support it. Together with the body 41, the four hook-shaped suspension supports 42 also descend. Next, the container 10 containing the bag S filled with unprocessed seeds on the carry-in conveyor 6 is suspended (locked) on one suspension support 42 positioned thereon. Next, the one air cylinder 43 is operated to raise the piston rod 43 a, and the lower surface of the container 10 is raised to a position higher than the upper end edge of the first hot tub 2. When the drive motor 54 is driven in this state, the horizontal rotating body 50 provided with the ring gear 53 is horizontally rotated in a certain direction, and the support body 41 is also horizontal via the sliding key 52 in FIG. 4B. Turn 90 degrees clockwise. Accordingly, the container 10 is positioned above a substantially central position in plan view of the first hot tub 2, and the right suspension support 42 in which the container 10 is not suspended is substantially at the center of the transfer unit 5. Come in position.

  Next, when the one air cylinder 43 is operated to lower the piston rod 43a, one support body 41 and four suspension supports 42 are lowered, and one container 10 is immersed in the first hot tub 2. Let At this time, since the suspension support 42 located in the transfer part 5 is also lowered, the container 10 containing the bag S filled with the next unprocessed seed cake is locked to the suspension support 42. By setting the time for immersing the container 10 in the first hot tub 2 to T1 time (for example, 5 minutes) in advance and storing it, the control means lowers the four suspension supports 42 for the T1 time. Then, the horizontal rotating body 50 is horizontally rotated in a certain direction by the operation of the drive motor 54, and the support body 41 is also rotated by 90 degrees through the sliding key 52 in a predetermined direction (FIG. 4 ( Control is made to rotate clockwise in b). In addition, in addition to the raising / lowering of the piston rod 43a, the total required time T2 for one turn for 90 degree rotation of the support body 41 is usually set shorter than the T1 time.

  As described above, the seeds in each container 10 can receive a cooling action for T1 hours after being subjected to a disinfection action by a warm bath for 2 × T1 hours. During the T1 time, the disinfected container 10 and the unprocessed container 10 may be replaced with the suspension support body 26 at the position by the transfer unit 5. In this way, disinfection of seed potatoes can be performed efficiently (time can be shortened). In addition, a cycle in which the control of operating the air cylinder 43 up and down and rotating the ring gear 53, the horizontal rotating body 50, and the support body 41 horizontally intermittently by the operation of the drive motor 54 is extremely simple is a cycle. Therefore, the control means can be simplified. Furthermore, since the four working parts can be arranged together in a cross-section partitioned in a plan view, the seed disinfection equipment 1 becomes extremely compact, and there is a remarkable effect that the required area of the facility can be reduced. Further, the replacement work of the container 10 in the transfer unit 5 can be performed by one operator, which has the effect of reducing the number of workers and the effect that the number of replacement containers 10 (the number of spares) can be reduced.

  In any of the above embodiments, the number of containers 10 corresponding to the number of working units are moved up all at once, and then the number of containers 10 are turned horizontally and intermittently in a predetermined direction at the rising position, The number of containers 10 are lowered all at once with respect to the work, and a processing cycle of holding a predetermined time at the lowered position of the container 10 is executed, so that the containers 10 are sequentially immersed in the plurality of hot tubs 2 and 3 sequentially for a predetermined time. In addition, the operating rates of the hot tubs 2 and 3 and one cold tub 4 are increased, the amount of disinfection treatment per unit time can be increased, and a remarkable effect is exhibited in improving productivity.

  The present invention is not limited to the above-described embodiment, but can be widely applied to various types of seeds other than seed pods, and can be embodied in various forms. For example, three hot tubs and one cold tub may be arranged, and a total of five working parts with one replacement part may be arranged radially around the rotation center axis of the support bodies 11 and 25 in plan view. Moreover, you may arrange | position radially with six working parts. In that case, the shape of each working unit in plan view may be substantially fan-shaped.

  And in the seed disinfection equipment 1 of the present invention, since there are a plurality of hot tubs and one cold tub, the value obtained by multiplying the immersion time for one hot tub by the number of hot tubs in the processing cycle described above. Since it is the total time for disinfection in the warm bath, the amount of disinfection treatment per unit time can be increased.

  Further, the lifting drive means (actuator) for moving up and down is not limited to the lifting cylinder, but may be an electric, hydraulic or pneumatic motor or the like.
