Moreover, energy cost is reduced and energy is saved.

  Moreover, since the room temperature is not lowered, the working environment of the worker is improved.

It is a perspective view of the topping line concerning the present invention. It is a longitudinal cross-sectional view of FIG. It is the perspective view which looked at the topping line which concerns on this invention from diagonally upward.

Hereinafter, embodiments of the present invention will be described with reference to FIGS.
In the figure, in the topping line, a belt conveyor 10 which is a conveying device is installed in the packaging chamber, and the lunch box 28 placed on the conveying surface 10a of the belt conveyor 10 is sequentially conveyed, and in the middle, the side dish is sequentially prepared. Etc. 30 are sequentially topped.

  In the illustrated example, two belt conveyors 10 are installed in series along the transport direction, and the belt conveyor 10 is provided with the cooling device 12 according to the present invention.

  The cooling device 12 includes a casing 14 that surrounds the belt conveyor 10 except for its conveying surface 10 a, a plurality of coolers 16 that are disposed in the casing 14 at predetermined intervals in the conveying direction of the belt conveyor 10, and the casing 14. It is comprised by the fan 18 each arrange | positioned facing one surface 16a of each cooler 16 inside.

  The casing 14 has side walls 20 a and 20 b that cover both sides of the belt conveyor 10 along the conveying direction of the belt conveyor 10. Inside the side walls 20 a and 20 b, inner walls 22 having rising portions 22 a and 22 b that protrude upward from the conveying surface 10 a of the belt conveyor 10 are provided on both sides along the conveying direction of the belt conveyor 10. The rising portions 22a and 22b are made of punching metal and have a large number of holes or openings. A space 26a is formed between the side wall 20a and the rising portion 22a of the inner wall 22, and the side walls 20b and the inner wall 22 A space 26b is formed between the rising portion 22b. A partition wall 24 is provided in the casing 14, and the cooler 16 and the fan 18 are fixed to the partition wall 24.

  It arrange | positions so that the other surface 16b of the cooler 16 may face the opening 24a formed in the one surface of the partition wall 24. FIG. The fan 18 is disposed in the opening 24b formed on the other surface of the partition wall 24, and the air intake surface 18a of the fan 18 is disposed so as to face the space 26b.

  Further, the refrigerant passing through the cooler 16 circulates through a condenser, a compressor, and an expansion valve arranged outside the casing 14.

  Using the topping line cooling device configured as described above, the operation of topping the side dish 30 on the lunch box 28 will be described.

  The belt conveyor 10, the compressor and the fan 18 are driven in a packaging room air-conditioned at a room temperature of about 20 ° C to 25 ° C. Thus, the fan 18 blows air toward the one surface 16a of the cooler 16, and the cold air obtained by the heat exchange through the cooler 16 passes through the space 26a from the other surface 16b. Is blown out from the rising portion 22a, crosses the conveying surface 10a of the belt conveyor 10 in the width direction, is sucked in from the other rising portion 22b, is sucked into the fan 18 from the space 26b, and is circulated.
