The low-temperature conveyor device 1 includes a heat insulating box 2 having a U-shaped cross-section with an open upper surface, a cold air discharge unit 3 provided at the center of the heat insulating box 2, and left and right sides of the heat insulating box 2. A suction cool air duct 4 provided on both sides and provided with a cold air suction port (not shown), a conveyor section 5 installed between the cool air discharge section 3 and the suction cool air duct 4, and the conveyor section 5, the cool air discharge section. 3, an intake cold air duct 4, and an article storage space 6 that is surrounded by the bottom wall 2 </ b> A of the heat insulation box 2 and keeps the object A to be cooled, and a stand 7 provided under the heat insulation box 2. Become. Note that a pedestal 7 </ b> A whose height is adjustable is attached to the gantry 7.
[0009]
The cold air discharge unit 3 includes a discharge cold air duct 8 located in the heat insulating box 2, a discharge cylinder 9 provided on the discharge cold air duct 8 and communicating with the discharge cold air duct 8, and an upper portion of the discharge cylinder 9. It comprises the discharge part 10 provided in.
[0010]
The discharge cold air duct 8 is formed wider than the discharge cylinder 9, and a step 11 is formed.
[0011]
Further, as shown by the white arrow in FIG. 1, the discharge portion 10 has cold air discharge ports 12 formed on both the left and right sides, and the cold air discharge ports 12 are formed with blow fins 13 for sending the cold air downward. Yes. Further, an air blower (not shown) for sending cool air in the left-right direction is formed in the middle part of the discharge cylinder 9.
[0012]
The conveyor unit 5 includes frames 14 and 14 and a plurality of rollers 15 installed between the frames 14 and 14. And this conveyor part 5 is provided on the level | step difference 11 of the said discharge cold air duct 8, and the suction cold air duct 4, as shown in FIG.
Further, as shown in FIG. 3, a hinge or the like is provided on the discharge cylinder 9 side of the frame 14 so that the frame 14 can be flipped up in the direction of the discharge cylinder 9.
[0013]
In the state of being flipped up, the flip-up state is held by a lock mechanism (not shown) provided on the hinge side of the frames 14, 14, or the jump-up state is held by the stay 16 provided in the discharge cylinder 9. Furthermore, the conveyor unit 5 itself may be detachable.
[0014]
The stay 16 has a structure in which a hook or the like is formed at the tip, and the hook is hooked on the frame 14 or 14 or the shaft of the roller 15 or the like.
[0015]
Further, the suction cold air duct 4 and the discharge cold air duct 8 are provided with a heat insulating material 17, and by this heat insulating material 17, the temperature rise of the discharge cold air in the discharge cold air duct 8 and the storage of articles by the suction cold air duct 4. The temperature rise of the work space 6 can be prevented as much as possible.
[0016]
Further, the suction cold air duct 4 and the discharge cold air duct 8 themselves may be formed of a heat insulating material.
[0017]
The low-temperature conveyor apparatus 1 as described above is generally used by connecting a plurality of units as shown in FIG.
[0018]
If the number of objects A to be cooled is not so large, the low-temperature conveyor devices 1A and 1B on the right side in FIG. 2 are used as work tables, and as shown in FIG. The space 6 is used to keep the cold.
[0019]
Further, when the number of objects A to be cooled is further small, the right low temperature conveyor device 1A is used as a work table, and the central low temperature conveyor device 1B is used for cold insulation. And since cold air can be sent only to the low temperature conveyor apparatus 1A and 1B to cool by stopping supply of the cold air to the low temperature conveyor apparatus 1C on the left side, there exists an energy saving effect.
[0020]
Next, the flow of cold air will be described.
[0021]
First, the cold air cooled by a heat exchanger (not shown) is sent to the discharge cold air duct 8 by a blower (not shown) and introduced into the discharge cylinder 9. Since the discharge tube 9 has a cold air discharge port 12 formed in the upper portion and a blower port formed in the middle portion, the cold air is discharged in the direction of the white arrow in FIG.
[0022]
And it cools the to-be-cooled object A working on the conveyor unit 5, falls into the article storage space 6 from the gap between the rollers 15 and 15 of the conveyor unit 5, is introduced into the suction cold air duct 4, It will return to the heat exchanger mentioned above.
[0023]
When used as a cold storage, the article storage space 6 is cooled by circulating cold air as shown in FIG. 1 in a state where the conveyor unit 5 is flipped up as shown in FIG.
[0024]
【The invention's effect】
As described above in detail, according to the present invention, a plurality of low-temperature conveyor devices are provided, work is performed on the conveyor portion of one low-temperature conveyor device, and the object to be cooled is kept in the article storage space of the other low-temperature conveyor device. I can do it.
[0025]
Therefore, it is not necessary to install another cold insulation device in another place, and the object to be cooled can be kept cold by the adjacent low temperature conveyor device, so that workability can be improved.
[0026]
In addition, some low-temperature conveyor devices can be cooled, and other cooling devices are not used, so energy for low-temperature conveyor devices that are not used and other devices is not required, and an energy saving effect is achieved. .
