The air pressurized feeding apparatus 100 according to the present invention includes a main body 110, a group of rollers 120, a nozzle 130, a nozzle driving unit 140, an air supplying unit, and a control unit, The present invention can be applied to the conveyance of a thin conveyance body which does not generate frictional force due to its own weight during conveyance.

The main body 110 includes a roller group 120, a nozzle 130, a nozzle driving unit 140, an air supply unit, and a control unit. The inlet and the outlet are formed in the front and rear walls, respectively, do. At this time, for example, paper (P) or the like can be applied to the thin conveying body, but the present invention is not limited to this, and it can be applied to an object having a thin shape.

A plurality of rollers 120 are disposed inside the main body 110 and are capable of conveying the thin type conveyer P in the course of rotation. The upper roller 122 is a roller for moving the paper P and the lower roller 124 rotates the upper rollers 122 in the same direction It is a roller.

The roller group 120 is further provided with an elastic roller 126 supported by an elastic force on the upper roller 122 disposed in front of the roller group 120 so as to be received between the upper roller 122 and the elastic roller 126 The paper P which is a conveyed article can be pulled out by the frictional force.

The nozzle 130 is disposed above the inlet-side upper roller 122 of the roller group 120 so that air is injected in the direction of the upper roller 122 so that self weight can be generated when the paper P is brought in.

At this time, the nozzle 130 is provided with an air jet opening 132 on the bottom surface thereof and a valve (not shown in the figure) is provided on an air supply line connected to the air jet opening 132 to control opening / This is possible. The air supply line is connected to the air supply unit.

Here, since the nozzle 130 is lightweight, it is conveyed through the group of rollers 120 to perform post-processing such as outputting or cutting of text or pattern on the paper P which does not generate frictional force due to its own weight The upper roller 122 provided on the inlet side generates a frictional force with the pressing force generated by jetting air onto the upper surface of the paper P to smooth the transportation.

Meanwhile, the nozzle 130 may have an arc shape, a mountain shape, a step shape, or the like, while the bottom surface of the nozzle 130 may have a plurality of air nozzles 132 formed therein.

At this time, it is preferable that the vertical length of the nozzle 130 is formed to correspond to the diameter of the upper roller 122 provided at the inlet with reference to FIG. This is to ensure that the supply range of the air supplied by the nozzle 130 is within the area of the upper roller 122.

When the air ejection openings 132 of the nozzle 130 are formed in multiple rows, air can be separately supplied to each row by an air supply unit.

In addition, when the air injection port 132 of the nozzle 130 is formed in multiple rows, the control unit controls the operation of the air supply unit so that the air injection pressure decreases as the air injection port 132 moves outward from the center position, Can be adjusted.

As a result, the air injection pressure is largest at the center of the nozzle 130 and becomes gradually weaker toward the edge, so that the pressing force becomes the largest at the center and decreases gradually toward the edge. Considering that the upper roller 122 is circular, the paper P is in line contact at the vertex of the outer circumference of the upper roller 122, but the distance between the paper P and the paper P gradually increases toward both sides of the outer circumference peak, The pressing force is gradually decreased toward the edge of the upper roller 122 in order to solve the problem.

The air injected from the nozzle 130 is simultaneously or sequentially injected into an air jet opening 132 formed in multiple rows by an air supply unit whose operation is controlled through a control unit.

When air is simultaneously supplied from the multi-row air jetting openings 132, the air is ejected after the leading end of the paper P is positioned within the air jetting area, and air is sequentially The air is jetted at this point when the leading end of the paper P starts to be positioned at the last air jet opening 132. [

Although it is not shown in the drawing, considering the fact that the roller is formed in a cylindrical shape by nature, a separate suction part is provided in front and rear of the nozzle 130 so as to suck the front and rear ends of the paper P in line- It is possible to prevent the front and rear ends of the paper P from sagging.

The nozzle driving unit 140 is provided to adjust an air jet direction of the nozzle 130, and a driving motor, for example, may be applied. Meanwhile, the nozzle driving unit 140 can be driven in the X, Y, and Z axis directions together with a rotation of a linear motor or the like.

Although not shown in the drawing, the air supply unit functions to supply air to the nozzle 130. [

Although not shown in the drawing, the control unit controls the driving speed of the roller group 120 and the driving of the nozzle driving unit 140 to control the angle of the nozzle 130, the opening and closing of the air jet opening 132, .

Therefore, the operation of the air pressure type feeding apparatus 100 according to the present invention is as follows.

First, the paper P, which is the object to be conveyed, is conveyed through the entrance formed on the front surface of the main body 110 of the conveying apparatus 110.

Next, when the leading edge of the paper P is moved toward the upper roller 122 provided at the inlet side, air is injected through the nozzle 130 provided on the upper roller 122, Thereby generating a frictional force with the upper roller 122.

The leading end of the paper P fed in the state of being closely contacted by air on the upper surface of the outer circumferential surface of the upper roller 122 flows between the upper roller 122 and the elastic roller 126, And is sucked inward by the driving of the elastic roller 126.

Next, the paper P sucked by the upper roller 122 and the elastic roller 126 is transported by the driving of the upper roller 122 disposed at the rear and is taken out to the outlet side of the main body 110, .

5 and 6 are a perspective view and a side sectional view showing a state where the upper roller of the air pressure type transfer device according to the present invention is provided with a sag prevention aid.

According to these figures, in the present embodiment, the upper end of the upper roller 122 is provided with an anti-sagging aid (not shown) at the upper end of the upper roller 122 to prevent sagging of the paper P when the paper P is fed by the rotation of the upper roller 122 150 are further provided.
