JPS60258041A - Device for turning direction of paper conveyance - Google Patents

Abstract

PURPOSE:To turn the direction in forwadig a form by 90 deg. in the case that the paper sheet is carried in or out of a tray with the aid of rollers, each of which is arranged along one edge and the adjacent edge normal to the above mentioned edge, by means of a roller which forwards the sheet toward the oblique direction striking it against stoppers at the both edges. CONSTITUTION:NO.1 stoppers 3 are arranged at the edge 1b of a tray 1, and NO.2 stoppers which can be moved up and down as required by means of a solenoid 7 to the stop or non-stop position, are arranged at the adjacent edge normal to the above mentioned edge. A paper sheet A is forwarded ont the tray 1 just under a paddle wheel 8 which makes approximate 90 deg. to the X direction by a carry-in roller 2, then is forwarded to the Y direction which makes approximate 45 deg. to the X direction until the sheet A comes in contact with the stoppers 3 and 5. By means of the wheel 8 with the stoppers 5 moved down to the non-stop position, the sheet A is then forwarded to carry-out rollers 4 along the stoppers 3 and subsequently toward Z direction which is turned by 90 deg..

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a sheet conveyance direction changing device that converts the direction of a sheet ejected from a copier or the like by 90 degrees and conveys the sheet.

Conventional technology First and second conveyance rollers are provided in the middle of the conveyance path to be perpendicular to each other, and the first and second balls can be pressed against and separated from the first and second conveyance rollers by the first and second solenoids. The first ball is placed in pressure contact with the first conveying roller to transport the paper to the second conveying roller.
There is known an apparatus that transports the ball to a transport roller, then separates the first ball and presses the second ball against the second transport roller to change the transport direction by 90 degrees.

Problems to be Solved by the Invention The cost increases because two balls and two solenoids are required, and the structure for supporting the two poles so that they can be fully pressed and separated becomes complicated, making the overall structure complicated. Become.

Means for Solving Problems and Action A carry-in port is provided at one orthogonal end edge of the tray and a carry-out roller is provided at right angles to one side edge, and a second stopper is provided at the - side edge to set the stop position and the non-stop position. A first stopper is provided on the other edge side, and a feed roller that conveys the paper diagonally with respect to the carrying direction is brought into contact with the top surface of the tray to change the paper conveyance direction by 90 degrees. It is possible to do this at a low cost and has a simple structure.

Embodiment FIG. 1 is a perspective view showing one end edge 1a of a flat tray 1.
A carry-in roller 2 is provided on one side, and a first stopper 3 is provided on the other edge 1h side.
A carry-out roller 4 is provided on the c side, and a hole 6 is formed in which a second stopper 5 moves in and out, and the second stopper 5 is moved up and down by a solenoid 7 to reach a stop position protruding from the tray 1 and a position below the tray 1. It can be moved freely to any non-stop position.

On the top surface of the tray 1 is a paddle wheel 8 that serves as a feed roller.
The paddle wheel 8 is connected to a shaft 10 driven by a motor 9, and the shaft 10 is slanted so that the paddle hole 8 is located at the corner between the other edge 1b of the tray 1 and the one side edge IC. It is slanted towards. In other words, the angle is approximately 45 degrees with respect to the carrying direction X.

However, the paper A is conveyed to the upper surface of the tray 1 by the carry-in roller 2 and enters between the upper surface of the tray 1 and the paddle wheel 8.

As a result, the paper A is conveyed by the paddle wheel 8 in the direction Y at approximately 45 degrees with respect to the carry-in direction
- Abuts on the second stopper 3.5.

Then, when the second stopper 5 is moved downward by the solenoid 7 to the non-stop position, the paper A is fed into the paddle wheel 8 and conveyed along the first stopper 3 to the carry-out roller 4. It is conveyed in the direction Z, which is a degree-changed direction.

In this way, paper A can be conveyed after changing its direction by 90 degrees.

Further, since it is not necessary to provide two balls as in the conventional case by using the paddle wheel 8, the cost is reduced and the structure is simplified.

Invention 0 Effects 11. The paper Af can be conveyed in the carry-out direction Z perpendicular to the carry-in direction X by the feed roller 8, and the paper A can be conveyed after being converted by 90 degrees.

Since the feed roller 8 is used, there is no need to provide two balls and two solenoids, and the cost is low and the structure can be simplified.
