Description

Non-electrical low-temperature sub-containers and hybrid logistics containers

The present invention relates to a logistics container, in particular to a non-electrical low-temperature sub-container and a hybrid logistics container having the non-electrical low-temperature sub-container.

Generally speaking, frozen or refrigerated items are transported and distributed using low-temperature logistics vehicles equipped with on-board refrigeration compressors. Before loading items, the cryogenic logistics vehicle needs to run the refrigeration compressor to produce a refrigeration effect in the cargo hold. However, the use of existing low-temperature logistics vehicles to carry items has the following practical limitations:

(1) Low-temperature items need to be delivered separately from normal-temperature items. Because low-temperature logistics vehicles are costly, they are usually not used to deliver normal-temperature items, and many normal-temperature items are not suitable for refrigerated storage. Therefore, for logistics operators, they often need to send out vehicles before they are fully loaded; for customers, if there are low-temperature items and normal-temperature items to be delivered, they need to pay the low-temperature freight and the normal-temperature freight respectively and process them twice ( Collection/delivery once at low temperature and once at normal temperature).

(2) When the cargo compartment door of a low-temperature logistics vehicle is opened to load items into the low-temperature logistics vehicle or unload items from the low-temperature logistics vehicle, the low-temperature air in the cargo compartment leaks out and the external high-temperature air flows in, causing the internal temperature of the cargo compartment to rise, affecting Cooling effect fruit.

(3) The refrigeration compressor in the cargo hold is electrical equipment. In order to avoid sparks from electrical equipment or fires caused by high temperatures, when the items delivered by low-temperature logistics vehicles are flammable materials (such as photoresist liquid or diborane gas and other electronic grade Semiconductor materials), it is best to use explosion-proof low-temperature refrigeration electrical equipment for low-temperature transportation to prevent sparks generated by non-explosion-proof low-temperature refrigeration electrical equipment from coming into contact with flammable materials.

In this embodiment, the first and second layers 121 and 122 are both made of mesh fabric; in other embodiments, only the second layer 122 may be made of mesh fabric and the first layer 121 may be made of other materials.

Referring to Figures 5 and 6, in order to prevent the cold insulation pieces 9 placed in the bag 12 from shaking and hitting the low-temperature items 8 contained in the cold insulation space S or hitting the heat insulation board 11 during transportation, the The low-temperature sub-container 1 also includes a plurality of guardrails 4 extending horizontally and each having two ends. The two ends of the guardrails 4 are respectively fixed to the rear, left and right inner wall surfaces 110e, 110c, 110d, thereby surrounding the bags hung on the rear, left and right inner wall surfaces 110e, 110c, 110d. Body 12.

It is worth mentioning that the fixing form of the first coupling members 31 of the present invention is not limited to the above. In other embodiments, the first coupling members 31 may also be installed through the inner wall surface 110b of the top heat insulation panel 11b. One or more slide rails (not shown) are slidably disposed on the inner wall surface 110b. Specifically, the slide rail may be a slide rail extending in a U-shape along the left, rear, and right edges of the inner wall surface 110b, or may be a slide rail extending along the left, rear, and right edges of the inner wall surface 110b respectively. Three slide rails. The number of the bags 12 is three and the length of each bag 12 in the vertical direction can roughly cover the corresponding inner wall surface 110 but is not limited thereto. The bags 12 are hung below the inner wall surface 110b of the top heat insulation panel 11b along the slide rail(s) and through the hooks and hanging ears.

Since the low-temperature sub-container 1 is housed in the normal-temperature container 2, that is, the size is smaller than the normal-temperature container 2, it is more suitable for loading the same customer's goods than the general refrigerated logistics truck, and can even be used to transport bonded goods. goods, and can directly lock and seal the entire low-temperature sub-container. In this case, the forklift can transport the entire low-temperature sub-container 1 by forking the forks into the grooves 140 formed by the support beams 14, and can be directly moved from the normal-temperature container 2 to the customer's cold storage warehouse. In this way, it is not only avoided that the insulating door panel 13 is opened and closed repeatedly to affect the temperature of the cold storage space S, but also ensures that the low-temperature items 8 do not need to be exposed to normal temperature air before being transported to the destination.

In addition, since the low-temperature items 8 can be placed on the pallet 80 and moved into the low-temperature sub-container 1 using a stacker, in order to reduce collision with the surrounding cold insulation parts 9 and heat insulation panels 11 during the transportation process, the low-temperature sub-container 1 is also Including the rear, left and right There are three anti-collision bars 5 at the bottom edges of the left and right inner wall surfaces 110e, 110c and 110d behind the side heat insulation panels 11e, 11c and 11d. The anti-collision bars 5 located on the left and right inner wall surfaces 110c and 110d are fixed to the corresponding inner wall surfaces 110 in a front-to-back manner, and their front end (that is, the end adjacent to the insulating door panel 13) is farther away from the inner wall surface 110c. , 110d is provided with a leading angle 50 at the corner. Thereby, the low-temperature article 8 together with the pallet 80 can be moved into the low-temperature sub-container 1 along the guide angle 50 .

In order to securely accommodate the low-temperature article 8 in the low-temperature sub-container 1 , a plurality of fixing holes 51 are provided on the upper surface of each anti-collision bar 5 . Thereby, tools such as ropes can hook or tie the low-temperature article 8, and then the ends are fixed to the anti-collision bar 5 through hooks or in a tied manner.

In summary, the low-temperature sub-container 1 of the present invention is accommodated in the normal-temperature container 2, so that the hybrid logistics container 100 can transport normal-temperature items and low-temperature items 8 at the same time; when the low-temperature sub-container 1 is used to load low-temperature items of the same customer 8. The low-temperature sub-container 1 can be moved directly to the customer's cold storage warehouse without affecting the temperature of the cold-storage space S; and since the low-temperature sub-container 1 is not electrical equipment, when the transported low-temperature items 8 are flammable materials, There is no need to use special explosion-proof refrigeration electrical equipment. It can be seen from this that the low-temperature sub-container 1 and the hybrid logistics container 100 of the present invention can indeed achieve the purpose of the present invention.
