It is arranged to be integrated into the media storage at high speed so that it can be integrated without jams.

Hereinafter will be described in more detail with respect to the configuration of the conveying guide and the stack roller constituting the media separation and integration device according to the present invention.

<Stack Roller>

4 is a perspective view showing the configuration of a stack roller constituting the media separation and integration device shown in FIG. 3, and FIG. 5 is an exploded perspective view for explaining a connection structure of the stack roller shown in FIG.

4 and 5, the stack roller according to the present invention is mounted on the same rotation shaft 310 as the guide roller 302, and may be installed in pairs on both sides of the guide roller 302. Of course, if necessary, it can be additionally installed in other positions.

The stack roller 300 is fixed to the rotation shaft 310 so as to rotate together with the rotation shaft 310, and a first roller 320 having a plurality of first stack sheets 322 formed only on a part of the outer circumferential surface thereof, and the first roller ( It is provided adjacent to 320, it is connected to be rotated only in one direction on the rotary shaft 310, and comprises a second roller 330 formed with a plurality of second stack sheet 332 only on a portion of the outer peripheral surface. At this time, at one end of the rotating shaft 310, a disc-shaped encoder (360) having at least one through hole formed therein is fixed to determine the rotation angle of the first roller (320), and the encoder (360) is provided. In the vicinity of the position is provided with a position detecting means (not shown) such as an optical sensor for detecting the rotation angle of the first roller 320 through the encoder 360. Here, the encoder 360 and the position detecting means (not shown) determine the stop position of the rotary shaft 310 for retracting the first stack sheet 322 and the second stack sheet 332 from the conveying path to which the medium is conveyed. In order to detect the rotation angle using the disk-shaped encoder 360 and the optical sensor in which the through hole is formed, the present embodiment is described. However, various types of encoders and various types of sensors capable of detecting the rotation angle are described. Of course, can be used.

The first roller 320 is fixed to the rotating shaft 310 to rotate together with the rotating shaft 310 along the direction of rotation of the rotating shaft 310 when the rotating shaft 310 is rotated, when the rotation of the rotating shaft 310 stops the rotating shaft ( At the same time as 310, the rotation is stopped.

The second roller 330 is connected to the rotary shaft 310 so that it can rotate only in the rotational direction of the rotary shaft 310, in the present invention, the one-way bearing for allowing the second roller 330 to rotate only in one direction ( By connecting to the rotary shaft 310 by using a one-way bearing, 340 was configured to rotate only in the rotational direction of the rotary shaft 310 on the rotary shaft 310. Accordingly, the second roller 330 rotates along the rotation direction of the rotation shaft 310 on the rotation shaft 310 when the rotation shaft 310 rotates, but rotates along the rotation shaft 310 when the rotation of the rotation shaft 310 stops. Inertia continues to rotate in the direction of rotation.

Through such a configuration, in the present invention, the first stack sheet 322 formed on the first roller 320 is stopped from the conveying path by stopping the rotation of the rotating shaft 310 at a desired position according to the rotation angle of the first roller 320. At the same time, the second stack sheet 332 formed on the second roller 330 may also be effectively evacuated from the conveying path by using the rotational inertia of the second roller 330. Here, the evacuation of the second stack sheet 332 using the rotational inertia of the second roller 330 will be described in more detail in the following description of the conveyance guide 400.

The first stack sheet 322 and the second stack sheet 332, which are formed only on a part of the outer circumferential surface of the first roller 320 and the second roller 330, are easily bent and restored, and have a high frictional force with a medium. It is preferable to be formed of a material having elasticity.

In addition, one side of the first roller 320 and the second roller 330 is a fan-shaped flange formed in a region having the same phase as the region where the first stack sheet 322 and the second stack sheet 332 is formed ( 350 may be provided respectively, and the flange 350 is connected to rotate together with the first roller 320 and the second roller 330 during the rotation of the rotation shaft 310. At this time, the flange 350 rotates together with the first roller 320 and the second roller 330 during the rotation of the rotary shaft 310, the upper portion of the flange protrudes on the conveying path to push up both ends of the medium to bend the medium. It plays a role of giving rigidity to media. The media can be integrated in the best state when stored in the media storage with both ends raised. In addition, when the rotation of the rotary shaft 310 is stopped, the flange 350 is retracted on the conveyance path together with the first and second stack sheets 322 and 332, and the lower portion of the flange 350 is formed in the conveyance guide 400. The predetermined length protrudes into the 402 and 404 to prevent a phenomenon that the medium carried out from the media storage portion is caught in the openings 402 and 404.

<Return Guide>

FIG. 6 is a view showing a top surface of a conveyance guide constituting the media separation and concentration apparatus shown in FIG. 3, and FIG. 7 is a view showing a side shape of the conveyance guide constituting the media separation and aggregation apparatus shown in FIG. 8 is a view showing a cross-sectional structure along the line AA of the transport guide shown in FIG.

6 to 8, the conveyance guide 400 is formed in a '-' shape having an obtuse angle in cross section, and a stack roller at a position corresponding to the first roller 320 and the second roller 330. A plurality of openings 402 and 404, which are used as passages for entering and evacuating the stack sheet during the rotation of the 300, are formed over the upper and side surfaces of the conveyance guide 400.

At this time, the opened length (x) of the openings 402 and 404 formed on the upper surface of the conveyance guide 400 is formed to be shorter than the length of the first and second stack sheets 322 and 332, and the conveyance guide ( The opened lengths y of the openings 402 and 404 formed on the side surfaces of 400 may be formed to have a predetermined length longer than the lengths of the first and second stack sheets 322 and 332.

That is, the opening lengths x of the openings 402 and 404 formed on the upper surface of the conveyance guide 400, which are the passages through which the first and second stack sheets 322 and 332 enter the conveying path, are defined by the first. And an inner wall of the transport path in which the first and second stack sheets 322 and 332 form the openings 402 and 404 when the rotation shaft 310 is rotated when the length of the second stack sheets 322 and 332 is shorter. The medium can be accumulated at a high speed in the media storage because it can hit the 405 and be unfolded by its elasticity and rotational force, and then bounce outwardly from the openings 402 and 404 to hit the conveyed medium more strongly. The length of the openings 402 and 404 formed on the side of the conveyance guide 400, which is a passage through which the first and second stack sheets 322 and 332 are evacuated from the conveying path, can be smoothly aligned. If (y) is formed longer than the lengths of the first and second stack sheets 322 and 332, the first and second stack sheets 322 and 332 may be evacuated. Than it is possible to easily take place.

In addition, when the conveyance guide 400 is configured as described above, the lengths of the openings 402 and 404, which are the passages through which the first and second stack sheets 322 and 332 enter the conveying path, are defined by the first and the second. Since the second stack sheets 322 and 332 are formed to be shorter than the length of the second stack sheets 322 and 332, the inner wall 405 of the transport path forming the openings 402 and 404 on the side where the first and second stack sheets 322 and 332 enter. This stopper serves to stop the second roller 330 freely rotating by the rotational inertia at the correct retracted position.

In other words, when the rotation of the rotary shaft 310 is stopped at an angle at which the first stack sheet 322 formed on the first roller 320 can be retracted on the conveying path, the first stack sheet 322 is thus conveyed. In this case, the second roller 330 is continuously rotated in the direction of rotation by the rotational inertia rotated along the rotation axis 310, and then the outer circumferential surface of the second roller 330 as shown in FIG. 8. While the second stack sheet 332 formed in the second guide sheet 332 strikes the inner wall 405 of the conveying path serving as a stopper in the conveying guide 400, the rotation of the second roller 330 is stopped, so that the second stack sheet 332 naturally forms a medium. Evacuate from the transport path.

9 is a view showing a cross-sectional structure of a conveying guide constituting the media separation and collecting device according to another embodiment of the present invention, except that a protrusion stopper 407 is formed at one lower side of the conveying guide 400. It is the same as the structure of the conveyance guide mentioned above.

That is, in this embodiment, the projection-shaped stopper protrudes a predetermined length on the inner wall of the conveying path forming the opening 404 which becomes the passage for the second stack sheet 332 of the second roller 330 to enter the conveying path. When the rotation of the rotary shaft 310 is stopped by forming the 407, the second stack sheet 332 formed on the second roller 330 hits the stopper 407, so that the rotation of the second roller 330 is stopped. Configured to stop. As described above, when the additional stopper 407 is formed on the inner wall of the conveying guide 400, the second stack sheet 332 hits the inner wall of the flat conveying path to stop the rotation of the second roller 330 as shown in FIG. 8. As compared with the case, the retraction of the second stack sheet 332 can be reliably performed by stopping the rotation of the second roller 330 more effectively.

Hereinafter, a method of integrating a medium by using the separation integrated device according to the present invention configured as described above will be described in detail.

FIG. 10 is a view illustrating an operation state in which media are integrated using a media separation and integration device according to an embodiment of the present invention.

Initially, the first stack sheet 322 and the second stack sheet 332 are evacuated from the conveying path to which the medium is conveyed and placed in the conveying guide 400 (a).

In this case, since the first stack sheet 322 and the second stack sheet 332 have the same phase and are provided in the retracted position, the first stack sheet 322 and the second stack sheet 322 may be used to effectively accumulate and separate the media during media accumulation. Since the stack sheet 332 rotates in a radial manner, initial driving for providing a phase difference between the first stack sheet 322 and the second stack sheet 332 is required.

Therefore, when the conveyance of the medium through the conveying path is detected, the rotary shaft 310 equipped with the first and second stack rollers 320, 330 (see FIG. 4) is rotated along the media stacking direction, and the first stack sheet 322. ) Stops the rotation of the rotary shaft 310 at the position entered on the conveying path, the initial drive for providing a phase difference between the first stack sheet 322 and the second stack sheet 332 is performed (b).

After the initial driving is performed and the rotating shaft 310 is stopped, the first stack sheet 322 is fixed while being exposed on the conveying path, and the second roller 330 is rotated by the rotating inertia 310. ), The second stack sheet 332 hits the inner wall 405 of the conveying path serving as a stopper, and the rotation stops, thereby naturally the first stack sheet 322 and the second stack sheet ( 332 is radially unfolded.

At this time, the rotation angle and the rotation stop position of the rotary shaft 310 for the initial drive is an encoder provided at one end of the rotary shaft 310, the position detection means for detecting the rotation angle of the first roller 320 through the encoder (not shown) Judgment is made through

Thereafter, by rotating the rotary shaft 310 to rotate the first stack sheet 322 and the second stack sheet 332 radially to accumulate the medium while continuously hitting the rear end of the conveyed medium (c).

In the above process, when the accumulation of the medium transported through the transport path is completed, the first roller 320 by stopping the rotation of the rotary shaft 310 at the position where the first stack sheet 322 is evacuated on the transport path, Stops the rotation together with the rotation shaft 310 so that the first stack sheet 322 is evacuated from the conveying path, and the second roller 330 continues in the direction of rotation by the rotational inertia rotating along the rotation shaft 310. And the second stack sheet 332 stops at a position where the second stack sheet 332 is retracted from the conveying path while hitting the inner wall 405 of the conveying path serving as a stopper, thereby the first stack sheet and the second stack sheet 322 and 332. (D) are all seated at a position to be evacuated from the conveying path.

In this case, the stop position of the rotary shaft 310 is determined by an encoder provided at one end of the rotary shaft 310 and a position detecting means (not shown) for detecting a rotation angle of the first roller 320 through the encoder. It is preferable to stop the rotation of the rotating shaft 310 at the position where the first stack sheet 322 is withdrawn from the conveying path.

Meanwhile, even in the case of the media separating and accumulating device according to the other embodiment shown in FIG.

At this time, through the stopper 407 of the projection shape projecting a predetermined length to the inner wall of the conveying path from the conveying guide 400, the agent continuously rotates on the rotating shaft 310 by the rotational inertia when the rotating shaft 310 is stopped after rotation. By stopping the second roller 330, it is possible to reliably evacuate the second stack sheet 332.
