Abstract

PURPOSE:To supply paper easily and efficiently by jetting air between a paper guided along a transport guide surface of a guide and the transport guide surface along the transport guide surface, thereby to transport the paper. CONSTITUTION:Air is jetted from a nozzle 18 between a smooth transport surface of a guide disposed along the direction of transporting a belt-like paper and the paper, whereby the paper is floated from the transport guide surface, and the thrust in the transport direction is applied onto the paper by the viscocity of the air. The paper is pressed by a driving roller 19 by pressure of the air, so that the paper is transported by the frictional force of the driving roller and the above viscocity of the air. Accordingly, the transport force is dispersed to work upon the paper, and the paper is pressed to the driving roller 19 by the pressure of the air, so that the paper is kept from being biased and crumpled. In this arrangement, a guide roller and the like are not required to simplify the structure. Furthermore, a take-up roll is not required to freely feed out and stop paper, and it is not necessary to reset the paper, so that a paper supply operation can be performed easily and efficiently.

Generally, in the process of manufacturing steel plates, for example, when these steel plates are stacked, a predetermined piece of paper is sandwiched between these steel plates. This paper is usually used in the form of a long strip wound into a roll. Conventionally, a device as shown in FIG. 1 has been used to feed the required amount of paper from such rolls. That is, 1 in the figure is a paper roll, and the paper 4 pulled out from the paper roll 1 is guided by a plurality of guide rollers 3 and is wound onto a take-up roll 2. Then, this paper 4 was rewound from the paper roll 1 by the required amount and used.

However, with this kind of paper, when the paper 4 that has been pulled out is cut, or when the paper 4 is cut midway, the paper 4 sags as shown in Fig. 2, and there is no way to restore it. It was necessary to guide the paper 4 again to the guide roller 3 and wind it around the take-up roll 2. For this reason, in this conventional device, the work of taking out the paper 4 was troublesome and inefficient.

Therefore, the air ejected between the conveyance guide surface of the guide body and the paper causes the paper to float from the conveyance guide surface, and the viscosity of this air gives the paper a thrust in the conveyance direction. The paper is conveyed along this conveyance guide surface. Further, the paper is pressed against the drive roller by the pressure of this air, and the paper is conveyed by both the frictional force of the drive roller and the viscosity of the air. Therefore, the force acts on the paper in a distributed manner, and the paper is pressed against the drive roller by air pressure, so that the paper does not become skewed or wrinkled. Further, since the paper floats up from the conveyance guide surface of the guide body by air, there is no frictional force between the paper and the guide body, and the paper can be fed reliably. Further, this paper does not require a take-up roll, and since the paper is conveyed while being guided along the conveyance guide surface, a guide roller is not necessary. Therefore, by simply inserting the leading end of the paper pulled out from the paper roll into this device, the paper can be freely fed out and stopped, and even if the pulled out paper is cut in the middle, the paper can be sent through the cellar 1 again. This is not necessary and makes the paper feeding process easier and more efficient.
