Abstract

PURPOSE:To separate and deliver mediums one by one irrespective of thickness, by a method wherein, when the medium is moved to a feed roller, a sensor is worked to force a subroller to be moved aside from the medium, and a main roller is caused to race. CONSTITUTION:When a magnet for motioning a solenoid is turned ON, a subroller 22 is brought into contact with a medium 11. In this case, by turning ON an electromagnetic clutch, coupled to a main roller 21, and rotating the main roller 21, a delivery belt 24 is rotated, the subroller is started to rotate, and by means of the main roller 21 and the subroller 22, the mediums 11 are separated from each other for delivery. When the medium 11 is moved to a feed roller 23, it is detected by a sensor 27, and when the sensor 27 is rendered effective, the magnet of a solenoid and the electromagnetic clutch of the main roller 21 are brought into an OFF-state, and the main roller 21 is started to race. In this case, the subroller 22 is not in a state to make contact with the medium. Namely, the subroller is moved aside to a position shown by a dotted line.

Description

[Detailed Description of the Invention] [Summary] In media separation and feeding, a main roller that is in constant contact with the medium and a sub-roller that is not driven once the medium is conveyed to the feed roller are provided, and the main roller and sub-roller are rotated when the medium is fed out. However, after the medium reaches the feed roller, the sub roller is retracted, the main roller is idled, and the medium is conveyed only by the feed roller.

[Industrial application field]

The present invention relates to a medium feeding method, and more specifically, to
The present invention relates to a method for completely separating and feeding out a medium by a combination of operations of a main roller, a sub roller, and a feed roller.

[Conventional technology]

Before sending bankbooks, certificates of deposit, transaction statements, etc. to the printer, these media are stacked and suspended in a media storage box, separated, and fed to the printer. Such a media separation mechanism is shown in cross-section in FIG.
1 is the medium, 12 is the storage box, 13 is the weight (!L)
, 14 is a feeding roller (also called a pick roller), 15
is separator rubber, 16 is separator rubber mounting bracket 1
It is fixed at 7.

In the above-mentioned conventional example, the medium 11 is pushed from above by the weight 13 while the feeding roller is rotated in the direction of the arrow to feed out one medium at a time starting from the bottom.

[Problem that the invention seeks to solve]

In the prior art, the separation function was performed by pressurizing the separator rubber against the bottom 18 of the storage box, which extends in the media feeding direction beyond the contour of the storage box. That is, as shown in the figure, pressure is applied until the separator rubber is slightly warped in the direction in which the medium is fed out, and the medium fed out by the feeding roller 14 is fed while being pressed.

By the way, the media ranges from 0.12mm thick to 0.12mm thick.
There are a wide variety of media, up to a thickness of 25mm+, and on the other hand, since the feeding roller and separator rubber are not in contact, a large feeding force cannot be obtained on the separator rubber, and 2 to 3 thin media of about 0 or 12mm cannot be separated at the same time. In some cases, the media may be fed out, or a medium of about 0.25 mm may not be fed out.

The present invention was created in view of these points, and it is an object of the present invention to provide a method in which media can be reliably separated and fed out one by one, regardless of thickness.

[Means for solving problems]

FIG. 1(a) is a front view of an embodiment of the present invention. In the figure, 21 is a main roller, 22 is a sub roller, 23 is a feed roller, 24 is a feeding belt, 25 is a separator, 26 is a pressure spring, and 27 is a sensor. It is.

In the present invention, a medium is provided with a sub-roller 22 that contacts the medium 11 by the operation of a solenoid (not shown), a feed belt 24 that drives the sub-roller 22, and a main roller 21 that is in constant contact with the medium and is equipped with a one-way clutch and an electromagnetic clutch (not shown). In the operation of the feeding mechanism, the medium 11 is fed out by operating the solenoid to move the sub roller 22.
contacts the medium 11, the feeding belt 24 rotates due to the rotation of the main roller 21, the medium 11 is separated and fed out by the separator 25 that presses the feeding belt, and the medium 11
is conveyed to the feed roller 23, the sub roller 22
is separated from the medium 11, the electromagnetic clutch of the main roller 21 is turned off, and the one-way clutch of the main roller 21 idles to prevent the next medium from being fed out.

[Effect]

According to the above method, in the process of separating and feeding out the medium 11, the main roller 21 and the sub roller 22 move, and when the medium 11 reaches the feed roller 23, the main roller 21 idles and the sub roller 22 stops rotating, so that the medium 11 is reliably fed. 1
They are separated and fed out one by one.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

Referring again to FIG. 1 (al), in the illustrated medium feeding mechanism, the medium storage box 12 is the same as in the conventional example, and the medium 11 is placed inside it and the medium 11 is held down by the weight 13.In the present invention, The main roller 21 and sub roller 22 are used to separate and feed out the medium 11. After the medium 11 reaches the feed roller 23, the main roller 21 idles, the sub roller 22 stops rotating, and only the feed roller 23 is used. It is configured to transport the medium 11.

To explain in more detail, the sub roller 22 takes a state in which it is in contact with the medium and a retracted state in which it is not in contact with the medium by the operation of a solenoid (not shown). A feeding belt 24 that drives a sub-roller 22 is connected to the main roller 21, and the main roller 21 is always in contact with the medium 11, and is equipped with a one-way clutch and an electromagnetic clutch (not shown). Further, the feeding belt 24 is in contact with the separator 25 which is pressurized by a pressure spring 26 .

In operation, when a magnet (not shown) that operates a solenoid is turned on, the sub-roller 22 comes into contact with the medium 11 . At this time, when the electromagnetic clutch connected to the main roller 21 is turned on and the main roller 21 is rotated, the feeding belt 24 rotates, the sub roller starts rotating, and the main roller 21 and the sub roller 22 separate the medium 11 and feed it out.

When the medium 11 reaches the feed roller 23, the sensor 27 detects it, and when the sensor 27 is turned on, the solenoid magnet and the electromagnetic clutch of the main roller 21 are turned off, and the main roller 21 starts idling. At that time, the sub roller 22 is not in contact with the medium. That is,
When the sensor 27 is turned on, the sub roller 22 is retracted from the position shown by the solid line in FIG. 1 to the position shown by the dotted line. The above sequence is shown in FIG.

When the media 11 leaves the feed roller 23, the sensor 2
7 detects it and then the process described above is repeated.

〔Effect of the invention〕

As described above, according to the present invention, media are reliably separated and fed out during operation of the medium feeding mechanism, and feeding errors and feeding of multiple media are prevented.
