められた。B. Prior Art Conventional truck beds are often equipped with conveyor belts as load transfer devices. In such a conveyor belt device,
A large number of support rollers are arranged along the lower surface of the endlessly wound belt, or alternatively, flat support members are arranged in an array to prevent the belt from sagging. When rollers are used as supporting members, gaps are created between the aligned rollers,
It has been found that when cargo is loaded on the belt conveyor, the belt gets stuck in the gap. Furthermore, this support mechanism requires additional equipment such as roller bearings, and therefore has the disadvantage of increasing manufacturing costs. On the other hand, when a flat belt support member is installed, the frictional resistance acting between the flat support member and the belt increases, and the driving power of the conveyor belt increases significantly. In addition, if cargo is loaded concentratedly at a specific location on the conveyor belt, the frictional heat caused by the concentrated load will cause the conveyor belt to
It was also recognized that there was a problem with the occurrence of a seizure phenomenon on the belt.

ことができる。 A large number of air blow-off holes 13 are opened on the upper surface 7' of the high-pressure air introduction chamber 7, and a pressurizing spring 17 is fitted into the air blow-off hole 13 so as to be movable up and down inside a cylindrical block 16. A one-way valve 8 having a ball 18 placed on a pressurizing spring 17 is fixed via a suitable fixing means such as a screw mechanism 15. The air blowing hole 13 may be directly formed in the conveyor belt support surface 7' of the high-pressure air introduction chamber 7, but the size of the ball 18 fitted into the air blowing hole 13 can be adjusted freely, and broken ball 1
In order to facilitate the replacement of the one-way valve 8, a hole is formed in an annular member 7'' that is integral with the one-way valve 8, and the annular member is screwed onto the upper surface of the main body of the one-way valve 8 to connect the high-pressure air introduction chamber 7. Preferably, a flush conveyor belt bearing surface 7' is formed.The bottom end of the cylindrical block 16 opens into the high-pressure air introduction chamber 7 via a vent 19, and the air enters through the air inlet 13'. High-pressure air is supplied to the conveyor belt support surface 7' of the high-pressure air introduction chamber 7 through the one-way valve 8 and the air outlet 13.

動用動力が大幅に減少する。 The operating procedure of the device of the present invention will be explained below. First, the air compressor 11 is activated to generate high-pressure air, and the valve mechanism 10 is opened to open the air inlet 13'.
The high pressure air is supplied into the high pressure air introduction chamber 7 through the high pressure air introduction chamber 7. On the other hand, since the ball 8 fitted in the valve 8 is strongly pressed against the annular member 7'' by the pressurizing spring 17 and closes the air outlet 13, the high pressure air supplied into the high pressure air introduction chamber 7 is Unless the ball 18 is pushed down by the weight of the cargo 20, it will not be ejected from the air outlet 13 and will be stored in the high pressure air introduction chamber 7. Note that the pressurizing spring 17
The strength of the conveyor belt 6 is adjusted so that the weight of the conveyor belt 6 does not push the ball 18 down, but the weight of the cargo 20 pushes the ball 18 down. When the cargo 20 is loaded onto the conveyor belt 6 in this state, the weight of the cargo 20 acts on the ball 18 of the one-way valve 8 via the conveyor belt 6, and the ball 18 resists the pressing force of the pressure spring 17. When the ball 18 is pressed down, a high-pressure air stream is ejected from the gap between the ball 18 and the air blowing hole 13. This high-pressure air pushes the conveyor belt 6 upward and forms a minute gap between the upper surface 7' of the high-pressure air introduction chamber 7 and the conveyor belt 6. A thin layer of air is thus formed between the upper surface 7' of the high-pressure air introduction chamber 7 and the back surface of the conveyor belt 6, which thin layer functions as a kind of air bearing. Therefore, the conveyor belt 6 is supported in a floating state, and the contact between the lower surface of the conveyor belt 6 and the upper surface 7' of the high-pressure air introduction chamber 7 is eliminated, and the frictional resistance acting on the contact surface is reduced. The power for driving the conveyor belt 6 is thus significantly reduced.

減と積荷の安定性向上を図ることが好ましい。 When the conveyor belt 6 loaded with the cargo 20 on its upper surface advances toward the front of the loading platform, that is, toward the back of the loading platform, the front part of the conveyor belt sequentially presses the balls 18 of the one-way valves 8 arranged in line. A gap for jetting out a high-pressure air flow is opened between the ball and the air blowing hole 13. The high-pressure air blown out from this gap supports the conveyor belt 6 in a floating state, thereby avoiding damage to the conveyor belt 6 due to rubbing. When loading and unloading the cargo 20, the conveyor belt 6, which moves back toward the rear end of the loading platform, sequentially releases the pressure on the ball 18 installed in the one-way valve 8. In this way, the ball 18 is pushed up by the pressurizing spring 17 and comes into close contact with the annular member 7'', closing the air blowing hole 13 and ending the ejection of the high-pressure air flow. - The belt 6 needs to be supported floating only when loading and unloading the cargo 20. Therefore, the valve mechanism is activated when loading the cargo onto the loading platform and when loading and unloading the cargo from the loading platform is completed. It is preferable to close the air compressor 10 and stop the air compressor 11 to reduce power consumption and improve cargo stability.

Effects of the Invention As is clear from the above explanation, by employing the device of the present invention, even cargo with a small bottom area can be maintained in a stable placement position on the conveyor belt. According to the present invention, when loading cargo, it is possible to place the cargo on the conveyor belt from the cargo entry port at the rear of the platform and automatically transfer the cargo to the front of the platform by simply driving the endless conveyance device. It is. The cargo loading and unloading operation can be carried out automatically in the same manner as the loading operation described above, but according to the reverse operating procedure. That is, the present invention provides a cargo transfer means with excellent labor-saving effects, and can completely eliminate the disadvantages found in conventional cargo transfer devices. Further, in the present invention, since the conveyor belt is supported in a floating state during movement under cargo loading, the frictional resistance acting on the conveyor belt is significantly reduced. Therefore, the conveyor belt can be manufactured from a thin sheet-like material that has less strength than conventional conveyor belts, which contributes to resource conservation and lower production costs for load transfer equipment. big. In addition, since the endless conveyance device is also miniaturized, power consumption is reduced, and an inoperable state due to insufficient battery capacity, which has been a problem when using a DC motor as a drive source, can be avoided. Therefore, there is no need to load a spare battery, and cargo loading and unloading operations can be carried out using only the standard battery.

It can also function well in That is, even if the ball 18 installed in the one-way valve 8 and the support members for the cargo load, such as the air outlet 13 that engages with the ball, freeze, the weight of the cargo 20 loaded on the conveyor belt 6 will cause the The frozen state of the support member of the load capacity is broken, and the ball 18 and the air blowing hole 13
Since the crushed ice is melted by the high-pressure air flow ejected from the gap, the floating support force acting on the cargo 20 and the conveyor belt 6 can be maintained at a good level even under low-temperature operating conditions. It will be done.
