Description

Detailed Description of the Invention 3. Detailed Description of the Invention Industrial Application Field The present invention is installed between a recording device such as a copying machine and a paper folding device, and changes the direction of paper ejected from the recording device. The present invention relates to a paper feeding direction converting device.

Conventional technology In particular, in copying machines for copying original drawings, etc., AO, A
Copies are often made on first-class large-sized copy sheets, and if these large-sized copy papers were stored as they were or handled as they were, the storage space would increase or the handling would be difficult. Because it is inconvenient, it is usually folded and stored. However, when paper is folded manually, it generally takes a considerable amount of time. For example, when copying on large copy paper, the time required to fold the paper is the same as that required for copying. In some cases, it can take several times as long as the actual time.

Therefore, an automatic paper folding device that is used in connection with a copying machine has been proposed in the past, and by using this automatic paper folding device, it is possible to significantly improve the copying efficiency of rough drawings, etc.

A typical prior art of such a paper folding device is JP-A-54-1035.

Problems to be Solved by the Invention However, in a recording device such as a copying machine connected to a folding device as disclosed in JP-A-54-1035, it is difficult to form a recorded image due to the configuration of the paper folding mechanism of the folding device. The paper to be folded must be conveyed vertically, with the short side as the leading edge. However, when recording paper is fed vertically, the document must also be scanned in the longitudinal direction, which takes time due to the long scanning distance. There will be a lot of wasted time.

Therefore, in recent high-speed copying machines and the like, models that scan the original along the short side of the original have been proposed because this reduces loss time and increases speed. However, in the case of such a copying machine, the copy paper is fed so-called horizontally with the long side as the leading edge, so there is a problem in that it cannot be folded as it is through existing paper folding devices.

The present invention has been made in view of these points, and its object is to provide a system that is installed between a recording device such as a copying machine and a paper folding device so that the feeding direction of paper on which a recorded image is formed is 90 degrees. An object of the present invention is to provide a paper feeding direction converting device that converts degrees.

Means for Solving the Problems In order to solve the above-mentioned problems of the prior art, the present invention provides a collision member at one end of the paper conveyance path so that the paper being conveyed collides with the collision member. A guide member extending in the paper transport direction is disposed on the same end side as the collision member on the downstream side, and the paper is rotated so as to separate from the collision member and transport the paper along the guide member after rotating the paper that collided with the collision member. - Provides a paper feeding direction converting device characterized by being provided with a conveying means.

According to a preferred embodiment of the present invention, the paper rotating/conveying means includes a conveyor belt disposed ↑゛1 with respect to the paper conveyance direction so as to approach the guide member as it goes downstream; The ball is made up of a plurality of balls that come into contact with the ball with a predetermined pressure.

A sheet of paper on which a recorded image has been formed, such as a working copy sheet, is conveyed with its longer side as the leading edge, and collides with a collision member provided at one end of the sheet conveyance path. The cartridge that collided with the colliding member is rotated approximately 9 times with the colliding member as the center of rotation by the paper rotation/conveying means.
01! The feeding direction of the paper is changed by 90 degrees by rotating the paper and conveying the paper with the long side of the paper along the guide member installed on the downstream side.

After changing the paper feeding direction in this manner, desired paper folding can be achieved using an existing paper folding device.

EXAMPLE 1 The present invention will now be described in detail based on embodiments thereof with reference to the drawings.

The paper transport path 10 is provided with transport roller pairs 12, 14, each of which is composed of a plurality of transport roller pairs as shown in FIG. On the downstream side of the conveyance rollers 114 (on one end of the paper conveyance path 10: there is a stud 16 at the position where the conveyed paper will collide).
is provided. Reference numeral 18 denotes a first paper conveyance means, which is composed of a conveyor belt [20] and a plurality of balls 22, 22 that abut against the conveyor belt with a predetermined pressure. The conveyor belt 20 is formed of, for example, a rubber belt, which is stretched endlessly around rollers 24 and 26.

The ball 22 is made of, for example, a steel ball.

Reference numeral 28 denotes a second sheet conveying means, which is composed of conveyor belts 1 to 30 arranged diagonally with respect to the sheet conveyance path 10, and balls 32 on a plurality of sides that abut the conveyor belt with a predetermined pressure. There is. The conveyor belt 30 is stretched in an endless manner over the Ll-Las 34 and 36, and is made of, for example, a rubber belt. Like the ball 22, the ball 32 is preferably made of steel LR, for example. A guide member 38 is provided downstream of the stud 16 and extends in the paper conveyance direction. Reference numeral 40 denotes transport L1 pairs, which are arranged in a plurality of rows in the width direction of the paper as shown in FIG.

In FIG. 2, reference numeral 12 indicates switching gears 1 to 'C, which are connected to means such as a solenoid (not shown) and are switched between the 1 upright position shown in FIG. 2 and the position where the paper conveyance path 10 is closed. . 44 is a bypass conveyance path, and a pair of conveyance rollers 46 is provided along this conveyance path.

Referring to FIG. 3, a partial cross-sectional view of the ball portion of the first paper transport means 18 is shown, in which a bracket 52 is secured across the baffle 48, 50, and a steel ball 22 is held in a holder 54. However, it is brought into contact with the conveyor belt 20 by a coil spring 56. Second paper conveyance means 28
The ball portion is similarly constructed.

However, the paper 11 discharged from a recording device such as a copying machine is conveyed into the conveyance path 10 with its long side as the leading edge.
The leading edge and the side of the sheet 11 abut against the stud 16 by the pair of transport rollers 12 and 14. When the leading edge and side of the sheet 11 collide with the stud 16 in this manner, the conveyor belt 20. Due to the action of the first paper conveying means 18 consisting of a ball 22, the paper 11 rotates around the stud 16 as shown by the dotted line in FIG. The sheet 11 is roughly rotated while being conveyed by a first stage 28 of second sheet conveyance consisting of a roller 30 and a ball 32, and the sheet 11 is rotated until the long side of the sheet 11 comes into contact with the guide member 38. Even if a rotational force is further applied to the paper 11 by the second paper transport means 28 in this state, the rotation is blocked by the guide member 38, and the paper 11 is eventually transported along the guide member 38 with its short side as the tip. The sheet is further conveyed by a pair of conveying rollers 40 and carried into a conventional paper folding device (not shown), where it is folded into an appropriate size.

If it is not desired to fold the paper ejected from a recording device such as copy R, the switching gate 42 is switched and the paper conveyance path 10 is rotated 113 times. When the switching gate 42 is switched in this manner, the paper is introduced into the bypass conveyance path 44, conveyed by a pair of conveyance rollers 46, and discharged into a discharge tray (not shown).

Effects of the Invention Since the present invention is configured as described in detail above, a so-called horizontally fed sheet of paper, which is conveyed with the long side as the leading edge, can be
Because it is possible to rotate the paper in a diagonal direction and change the conveyance direction of the paper to so-called vertical feed, in which the paper is conveyed with the short edge as the leading edge, there is no need to develop a dedicated folding machine for the horizontal feed recording device.
The effect is that a conventional paper folding device can be used simply by connecting the paper feeding direction converting device of the present invention.
