- FIGS. 1 and 2 a device for unloading loads according to a first preferred embodiment of the present invention.
- the device for unloading loads includes at least one air tube 100, a pump 150, a sensor 300 and a controller 400.
- the unloading device according to the present invention may mounted on the inside or the outside of a carrying box 1000.
- the carrying box 1000 means a structure in which lots of things can be loaded.
- inner walls of the carrying box 1000 are called a front face and a rear face, a top face and a bottom face and side faces on the basis of a progress direction of transportation means.
- the carrying box 1000 may be mounted on the transportation means or an independent structure.
- the carrying box 1000 means a structure having a space for loading lots of things like an on-board carrying box of a truck which deliver goods.
- the air tube 100 is made of a flexible material which is expandable and contractible in volume according to injection and discharge of gas in order to push the loads out when the air tube 100 expands by injection of gas.
- the air tube 100 may be divided into a gas injection/discharge part, a body part and a pressing part.
- the gas injection/discharge part serves to inject gas into the air tube 100 or remove gas from the air tube 100, and is connected with the pump 150 which will be described later.
- the body part is actually a part that the air tube 100 is expanded and is made of a flexible material. It is preferable that the body part be at the least more than half of the length ranging from the front face to the rear face of the carrying box 1000 when the body part is expanded to the maximum.
- the pressing part means the part that the body part directly touches the outer face of the loads when the body part is expanded, and preferably, has a form to absorb shock.

- the pressing part may have shapes of various figures or three-dimensional shapes besides the hemispheric shape.
- the unloading device includes the pump 150.
- the pump 150 is a device to inject gas into the air tube 100 or discharge gas out of the air tube 100.
- the pump 150 may be mounted on the inside or the outside of the carrying box 1000 to inject or discharge gas using the principle that materials move depending on difference in air pressure.

- the controller 400 controls an injection speed (pressure), an injection amount and an injection period of time that the pump 150 injects gas to the air tube 100 and controls expansion speed and volume of the air tube 100 according to kinds of the loads. For instance, in a case that the loads are fragile, the controller 400 makes the pump 150 inject gas at low pressure so that the air tube expands at a slow speed. Therefore, the air tube which expands at a slow speed pushes out the loads slowly so that the loads can be unloaded in safety without any breakage or damage.
