This application claims priority to Japanese Patent Application No. 2021-132998 filed on Aug. 17, 2021, incorporated herein by reference in its entirety.
The present disclosure relates to a self-propelled food delivery pallet.
Japanese Unexamined Patent Application Publication No. 6-305357 (JP 6-305357 A) discloses a technique relating to a cooking vehicle including a cooker using a combustor. In this related art, the air intake/exhaust port of the combustor inside the body of a closed-type cooking vehicle that is sealed and used during cooking is directly communicated to the outside of the vehicle body without going through the operation room inside the vehicle body, so that the high-temperature combustion air generated by the heat of the combustor is exhausted to the outside of the vehicle body without going through the operation room inside the vehicle body. Accordingly, the ventilation inside the vehicle body can be adjusted and the room temperature can be adjusted to an appropriate temperature.
Since the above-mentioned related art assumes that a cook operates inside the vehicle body, it is necessary to improve the environment inside the vehicle body as described above. However, for example, when considering unmanned delivery services such as food delivery, it is necessary to ensure safety for people near the traveling vehicle body.
In view of the above facts, an object of the present disclosure is to provide a self-propelled food delivery pallet capable of ensuring safety for people nearby.

A self-propelled food delivery pallet according to an embodiment of the present disclosure will be described with reference to the drawings.
Outline
As shown in
The delivery system 10 provides, for example, a service in which the food P designated by the user is accommodated in the food delivery pallet 16 and delivered to the delivery destination designated by the user. The food delivery pallet 16 can travel by itself between the store 12 at which the food P is supplied and the user's home 18 at which the food P is received. Although the user who purchases the product and the recipient who receives the product may be different, in the present embodiment, for convenience of explanation, the case where the user and the recipient are the same will be described.
Configuration of Self-Propelled Food Delivery Pallet
First, the configuration of the self-propelled food delivery pallet according to the present embodiment will be described.
As shown in
On an upper surface (outside) 22A of the food delivery pallet main body 22, for example, an electric bulletin board (display unit) 24 as a warning unit is provided. The electric bulletin board 24 is provided in an upright state with respect to the upper surface 22A of the food delivery pallet main body 22, and is disposed along the longitudinal direction (arrow A direction) of the food delivery pallet main body 22. For example, warnings such as “Heating! Caution!” are displayed on the electric bulletin board 24. In addition to this, the warnings are appropriately selected according to the content to be noted, such as hot, cracked objects, heavy objects, and during cooking. It should be noted that the display unit does not necessarily have to be the electric bulletin board 24 as long as the warnings are noticeable.
Further, as shown in
Here, the food delivery pallet 16 may be configured to be capable of wireless power supply that enables supplying power in a non-contact manner. When traveling on a road surface in which a power transmission coil is embedded, a power feeding coil may be provided on the food delivery pallet 16, and current may be passed through the power transmission coil to supply electric power to the power feeding coil of the food delivery pallet 16. Accordingly, the food delivery pallet 16 can be supplied with electric power while traveling.
A part of the upper portion 22B of the food delivery pallet main body 22 and a part of the lower portion 22C of the food delivery pallet main body 22 are partitioned by a partition wall 36 with a heat insulating effect, which constitutes a structure in which heat transfer is not performed between the part of the upper portion 22B and the part of the lower portion 22C of the food delivery pallet main body 22. Further, a partition wall 38 is provided between the cooling chamber 32 and the heat retaining chamber 30, and a partition wall 40 is provided between the heat retaining chamber 28 and the heat retaining chamber 30. Similar to the partition wall 36, the partition wall 38 has a heat insulating effect, which constitutes a structure in which heat transfer is not performed between the cooling chamber 32 and the heat retaining chamber 30. However, the partition wall 40 does not necessarily require a heat insulating effect, and the heat of the heat retaining chamber 28 may be transferable to the heat retaining chamber 30.
As described above, the heating chamber 26 is provided on the upper portion 22B of the food delivery pallet main body 22. A lid portion (not shown) is provided on the upper portion of the food delivery pallet main body 22 so as to be openable and closable. With the lid portion open, the heating chamber 26 can be exposed. The lid portion can be opened and closed only by the store 12.
As shown in
A heater 52 is provided inside the transport belt 42, and the heater 52 heats the lower surface sides of the pizzas 48, 50. Further, with the lid portion of the food delivery pallet main body 22 closed, a heater 54 is set to be disposed above the transport belt 42, and the heater 54 heats the upper surface sides of the pizzas 48, 50. That is, in the heating chamber 26, the pizzas 48, 50 can be heated and cooked. Therefore, the pizzas 48, 50 before being heated can be placed on the transport belt 42.
When the heating of the pizzas 48, 50 is completed, the rollers 44, 46 rotate at a constant angle. Accordingly, of the pizzas 48, 50 placed on the transport belt 42, the pizzas 50 placed on the roller 46 side drop from the transport belt 42, and are guided to the packing chamber 34 provided next to the heating chamber 26. Decorative boxes 56 are arranged on the downstream side in the transport direction (arrow B direction) of the pizzas 48, 50, that is, in the packing chamber 34, and are set so that the pizzas 50 that have dropped from the transport belt 42 are accommodated in the decorative boxes 56.
For example, a guide plate 57 is disposed on the downstream side in the transport direction of the pizzas 48, 50, and the decorative boxes 56 are arranged further on the downstream side of the guide plate 57. The guide plate 57 and the decorative boxes 56 are arranged so as to be inclined downward in a direction away from the transport belt 42, and the pizzas 50 that have dropped from the transport belt 42 slide down the guide plate 57 so as to be accommodated in the decorative boxes 56.
An opening (not shown) is thus provided on a side wall 56A side of the decorative box 56, and the pizza 50 is accommodated in the decorative box 56 through the opening. The side wall 56A of the decorative box 56 is bent upward, and when the pizza 50 is accommodated in the decorative box 56, the side wall 56A is bent downward to close the opening. In this way, the decorative box 56 with the closed opening drops downward to be placed in the heat retaining chamber 28.
Although not shown, new decorative boxes 58 are arranged on the upper portion of the packing chamber 34, and when the decorative boxes 56 drop, the decorative boxes 58 are moved downward. When the new decorative boxes 58 are arranged on the downstream side in the transport direction of the pizzas 48, 50, the rollers 44, 46 further rotate. Accordingly, the pizzas 48 remaining on the transport belt 42 drop from the transport belt 42 to be accommodated in the decorative boxes 58. When the openings of the decorative boxes 58 are closed, the decorative boxes 58 drop downward and are placed in the heat retaining chamber 28 so as to be stacked on the decorative boxes 56 from above.
As described above, the pizzas 48, 50 heated and cooked in the heating chamber 26 are each packed in the decorative boxes 56, 58, and arranged in the heat retaining chamber 28.
In the present embodiment, as described above, the opening is provided on the side wall 56A side of the decorative box 56. However, it is only necessary that the heated and cooked pizza 50 can be packed in the decorative box 56, so that the packing method is not limited to this, and it goes without saying that the pizza 50 may be packed from the upper side of the decorative box 56. However, in that case, as compared with the above embodiment, it is necessary to increase the space in the packing chamber 34 along the longitudinal direction (arrow B direction) of the transport belt 42.
As described above, the lower portion 22C of the food delivery pallet main body 22 is provided with the heat retaining chamber 28, the heat retaining chamber 30, and the cooling chamber 32 for keeping the food P to be delivered. As shown in
The drawer-type tray 64 is provided with a drawer recess 64A along a substantially horizontal direction. A finger can be hooked in the drawer recess 64A. By hooking the finger in the drawer recess 64A, the drawer-type tray 64 is pulled toward the front using the drawer recess 64A, so that the food in the heat retaining chambers 28, 30 and the cooling chamber 32 can be taken out.
As the food P to be delivered, the pizzas 48 and the pizzas 50 are accommodated (kept) in the heat retaining chamber 28, and heat-retained food 60 other than the pizzas 48, 50 such as pasta, chicken, and potatoes is accommodated (kept) in the heat retaining chamber 30. Further, cooled food 62 to be cooled, such as salads and beverages is accommodated (kept) in the cooling chamber 32.
On the upper surface 22A of the food delivery pallet main body 22, for example, a code reading unit 68 for unlocking a lock device 96 (see
