Abstract

PURPOSE:To make it possible to deliver sheets of paper one by one positively, by providing a paper sheet attracting and delivering mechanism with opposed arrays of small openings through which air currents are blown to the sides of the stacked sheets of paper. CONSTITUTION:The sheets (Q) placed on a table 8 are attracted by suction nozzles 24 in a rotating drum 21 and are led into a pinching port 27. At this time, the higher the position of the sheets (Q) is, the more the air is blown from the small openings 15 in a pair of blowing cylinders 14a, 14b, so that the uppermost sheet (Q) is positively separated from the rest and is prevented from being inclined because the air currents are blown from opposite directions. If two sheets are going to be delivered, the lower sheet is prevented from being delivered since the lower sheet is sucked by the sucking action of suction openings in a suction cylinder 11.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a paper conveyance device, which is capable of feeding nine stacked paper slips one by one in the correct form. Related to industrial delivery devices.

[Technical background of the invention and its problems]

Conventionally, a delivery port 1 is known that sends out a plurality of stacked paper sheets one by one to a desired location. Such a paper i** feeding device is generally used to stack nine papers*m on a table and sequentially print out the paper products located in the Nk table "-".
The paper is taken out from the stacking position by vacuum suction transfer or friction feeding, and is configured to be fed, for example, between conveyor belts.

By the way, regarding this type of feeding device,
Because the paper sheets are set in a stack, when the paper industry used for helicopter use and the nine paper mounds adjacent to it are in close contact, two or more sheets may be sent out at once, or Further, when the adhesion force is large, it may not be sent out. Therefore, in order to eliminate such misalignment, an air flow is usually blown in the direction opposite to the paper cutting direction of the above-mentioned paper industry onto the end face of the stack II of the paper keys, and by this blowing, the paper 'sl [ A gap is forcibly formed between them, and the presence of this 1-retainer reduces the adhesion force.

However, in the case of a device that uses a method of blowing airflow to reduce the adhesion between sheets as described above, the gamma balance of the nine sheets formed, the thickness of sheets Due to the unbalance of the For example, in the middle of the transport system, Kl! I
If all the reading devices use this reading device to scan the surface of a traveling paper sheet in a direction perpendicular to the direction of travel and read the data written on the surface, the reading cannot be performed.

[Purpose of the invention]

This invention was made to solve the above-mentioned deficiency.
The object thereof is to provide a paper sheet I-outputting device that can feed and output paper sheets one by one without causing the paper sheets to be tilted.

[Summary of the Invention] A row of small holes are provided facing each other to blow an air flow toward a stack of paper products WJ that is close to the paper products suction and feed machine 11jK and parallel to the feeding direction. The product I of paper mll+ gradually becomes denser in one direction [4IA
Effect of #4] Therefore, 1 of the mounting table with G111IIl horizontally 1
As the paper rises, the paper sheets begin to be separated excessively by the air flow in the row of small holes, and the moths and paper sheets are attracted to the suction feeder fl.
When Ift is increased to the extent that it is close to lK, paper sheets near the suction feeder WI441 have a large gap between the paper sheets, allowing for good separation of paper sheets. Only the end in the feeding direction is lifted by the air flow, and the suction feeding mechanism
It is possible to achieve suction that is unique to the paper industry, thereby facilitating and ensuring reliable feeding. Since the paper sheets are made to sing by blowing the airflow in opposite directions, it is possible to prevent the so-called tilting of the paper-IIm from occurring.
It can be sent out with normal Suginobu. therefore.

The information reading device for the paper industry used in the conveyance section can be operated satisfactorily, thereby improving the performance of the paper type II handling device.

[A series of inventions]

The details of the present invention will be explained below with reference to I7 shown in the drawings.

1411gJ is a side view showing a main part of a paper sheet feeding device according to a centralized example of the present invention. In the figure, reference numeral 1 denotes a frame, and bearings 2aI2b are fixed to this frame 1 via supporting members in vertically opposing 1-parts, and a rolled ball screw 3 is rotatably supported by these bearings 2at2b. ing. The upper end of the rolled ball screw 3 is connected to a rotating shaft of a motor 5 via a speed reduction mechanism 4. A rolled ball nut 6 is screwed onto the outer periphery of the above-mentioned rolling stock screw 3, and the ball nut 6 has a support 1 on the upper surface of which paper products Q are placed in a laminated form 9. 8 is fixed horizontally. On one side of this mounting table 8, 41I! A position detector 9 formed of a limit switch, etc., which sends an OFF signal when the paper '#4 type Q located at the top 1- of the paper products Q placed on the paper comes in contact with it, and sends an ON signal when it does not make contact with it. At this point, the motor 5 is controlled to rotate (normally rotate) 11 in response to the ON signal of the +1 detection foot 9 so as to raise the rolled pole nut 6 in the direction indicated by the arrow 10 in the figure. Therefore, the paper sheets Q located in the isthmus LIill are always maintained at a constant height.

Incidentally, the motor 5 is designed so that reverse rotation and stop control can be selectively performed by external control.

However, when he was 1 year old, the left side of table 8 had the above 4! : Place the left end surface of the paper 111Q stacked 1 on the board 8 at the position 1i.
An intake cylinder 11 shaped like an eccentric hexagon is provided so as to restrict the air flow. The upper part of this intake cylinder 11 is Mogami JI
As shown in FIG. 2, it is blocked by a plate 12 at a position approximately at the same height as the sheet 11Q located at K position.
This plate 12 has intake holes 1 divided into 5 rows and 5 columns, for example.
3 is formed.

The lower end of this intake cylinder 11 in FIG. 1 is connected to an intake pump PIK. On the other hand, at the upper end and both side surfaces of the intake pipe 11, there is a relationship shown in FIG. A pair of spray cylinders 14a and 14b are provided as shown in FIG. The side 1ii1gK of the stacked paper sheets Q of these blowing tubes 14a and 14b has a wall opposite to the stacked paper sheets Q so that the amount of air blown out is larger in the upper part than in the lower part in one direction as shown in Fig. 3. A row of small holes 15 is formed, and
The spray tubes 14a and 14b are each connected to an exhaust pump C1.

Above the intake cylinder 11, a rotating drum 21 with a diameter of 11 narrower than the paper 11 is provided with its axis oriented in a direction perpendicular to the plane of the paper in FIG.
A suction hole 22 is formed in each of the opposing portions of the peripheral wall. Note that the rotary drum 21 is rotationally driven by a drive source 1 in the figure in the direction indicated by an arrow 2B in the figure, for example, at a constant speed. Inside the rotating drum 21,
A suction nozzle 24 is fixed with its open end directed toward the inner circumference of the rotating drum 21. The inner surface 24a of one wall that restricts the opening 1@ of the suction nozzle 24 in the opening direction is the uppermost 1-
It extends from the left end of the paper sheet Q placed in number 1 toward the number position in the counter-rotation direction of the rotary drum 210, and the inner surface 24b of the other 1 extends toward the position to the left of the suction pipe 11. . The suction nozzle 24 is connected to the suction pump P2.

Therefore, on the upper left side of No. 11511 of the placing table 8, there is a pair of upper and lower conveyor bells) 31#32 with an arrow 33m in the figure.
Two pairs are provided in parallel so that they run in the direction shown by =33b. The upper conveyor belt 31 among these conveyor belts 31 and 32 has guide rollers 34 and 36
The rotary drum 21 is coaxial with the rotary drum 21, and the rotary drum 21 is loaded via an idle roller (not shown) with a small diameter.
The conveyor belt 32, which is placed at the bottom of the conveyor belt 32, runs to the first station via the E side of the nine sheets Q.
The vehicle is traveling to 1!114 via 36-i4 to the left of the paper industry Q loaded with paper products. And both a sending bell) 3
They overlap at the position of the 1#321d guide roller 35, and a V-shaped insertion opening 37 is formed on the right side of this 11 point.

Next, the operation of the present invention AT configured as described above will be explained.

First, the motor 5 is reversed to lower the mounting table 8 at a low position lft, and in this state, a plurality of paper sheets Q are placed on the mounting table 8 in a stack as shown in FIG. 111. Place the Ic. Next, the rotary drum 21 is started to rotate, the 41 feed belts 31-32 are started to run, and the intake pump Pl.
P2 and exhaust pump C Sumire are operated, and the motor 5 is switched to the normal rotation side.

In this state, the paper industry Q located at the top is not in contact with the position detector 9, so the motor 5 continuously rotates in the forward direction, and as a result, the 11[stand 8] gradually rises. Then, when it rises to a certain position, the paper leaf located at the top 1 @
Q contacts the position detection 89, and as a result, the rotation of the motor 5 is stopped and the raising of the mounting table 8 is stopped. Therefore, the paper sheet Q located at the top 1 is always kept in a constant position.

On the other hand, since the rotating drum 21 is rotating in the direction shown by the arrow 23 in the figure, each time the suction hole 22 provided in the peripheral wall passes the front surface of the suction nozzle 24, the paper industry Q located at the uppermost l- A suction force acts on the left end in the figure, and the paper sheet Q located in the upper layer of this **% moth is attracted to the surface of the rotating domme 21. The absorbed whetstone 1!1 IIQ is rotated 210 times by the rotating drum.
Accordingly, it was moved to the left in the middle of the illumination and inserted into the hole 37.
It is finally carried between transport bells (31=32) to a desired location.

However, as mentioned above, paper slip 11Q located at the top 11
are sent out one after another by the so-called suction-feeding-paper-dispensing mechanism. Since the pair of small hole rows IS blows air toward both sides parallel to the meat, the paper sheets Q that are stacked closely together in one direction are separated from each other without tilting in one direction. Ru.

In addition, the rows of small holes 15 are arranged so that a large amount of air flow is generated at the top in the stacking direction of the paper products, so that paper products that are close to the giga suction drum 21 that is stacked are One gap between the paper sheets becomes extremely hot, and only the ends of the stacked paper sheets in the paper feed direction are lifted up by the air current, and the suction and feed mechanism realizes suction of only the top layer of paper sheets. There is.

Therefore, the feeding is not hindered by the adhesion force in the stacking direction, and the paper products Q are prevented from tilting due to the blowing of the countercurrent, so that each sheet is fed in its normal form. Extracted.

Moreover, even if the feeding of 10,000-2 sheets is attempted, the intake cylinder 11
The suction action prevents paper sheets Q located below from being fed out.

[Other inventions! ! Example]

In addition, in the above-mentioned example, the spiral paper leaves are stacked in the same direction as the moving direction, but the present invention is not limited to the moving direction; for example, the present invention can also be applied to sheets stacked in the direction perpendicular to the moving direction Can be applied. In addition, in the above-described embodiment, the row of small holes in the spraying part is described as a small circular hole because it can be easily processed, but the shape of the hole is not limited to a circle, and may be, for example, an oval or a slit. Good too. Moreover, although the small hole row is explained as one row, it may be a plurality of rows.
