Abstract

PURPOSE:To enable feeding out even rolled paper one by one sheet in such a way that a turning feed-out mechanism to feed out the paper sheet at the uppermost laminate layer by means of adsorptive force on the convex outer periphery is installed opposite to the concave face of the paper sheet on the laminate layers to be fed which has been incurvated. CONSTITUTION:When laminate layer materials X are sent up in keeping with rise of a paper holding stand 8 by means of turning of a motor 5, the side faces of the laminate layer materials X parallel with both directins of feed-out and the laminate layer materials are brought into contact with the outer faces of rollers 36a, 36b, rubbed up, and incurvated. And since friction resistance between a belt body P and the uppermost laminate layer paper sheet Q becomes vary less by means of incurvation, the convex outer periphery of a drum 13 comes to go along the surfaces of the paper sheets Q, in consequence, the adsorptive force through an adsorptive hole 15 of the drum 13 is effectively worked to the paper sheets Q, so that feed-out of paper sheets becomes easy, and in the result, they can be favorably fed out one by one sheet.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a paper sheet feeding device Klway, which can feed paper sheets one by one without breaking the band, even if the sheets are bundled by a band. Paper sheet feeding device K1
Take 1l.

Various types of feeding devices have been known in the past for feeding stacked sheets of paper one by one to a desired location.
Such a paper sheet feeding/unloading device is generally used to stack paper sheets on a table and sequentially transfer the paper sheets located in the upper layer by vacuum suction or abrasion by the amount of good paper mm. The structure 1 is such that the material is taken out from the stacking position and fed to the conveyor belt.

However, even with the configuration as described above, there are the following problems. In other words, the paper sent out *
m' are not necessarily all in the same form; for example,
As shown in tIXlla, a plurality of paper sheets Q, a band PK
Therefore, even if the laminate is tightly bundled, it will still have an O□%. A laminate like this! In order to send out the band P one by one using the feeding device (4y), K needs to tear or pull out the band P in advance. The so-called removal work is generally carried out by Operator I, and it is refreshing that the existence of this removal work is hindering the efficiency improvement and labor saving of Paper Form III. There was.

The present invention has been made in view of the above circumstances, and its purpose is to collect good quality paper mm bound by a band.
However, Jin and K offer an aSS feeding and unloading device that can feed one sheet at a time in a single layer, greatly improving processing efficiency and labor saving by increasing the processing efficiency by 45%.

That is, the feature of the paper sheet feeding/dispensing device according to the present invention is that it is provided with a means for making the laminate of the paper sheets ** to be sent into a wand, and the paper sheet feeding/dispensing device according to the present invention is provided with a means for making the laminate of the laminate to be undulated. A rotating speed release mechanism having a convex curved outer circumferential surface corresponding to the concave curved surface is provided facing the concave curved surface, and the cup is attached to the outermost layer of the laminated body by the force of the convex curved outer circumferential surface or the adsorption force to the convex curved outer circumferential surface. There are nine ways to feed the paper sheets placed one by one in the direction along the concave-to-tani line.

Therefore, according to the present invention, since the stack of paper sheets to be sent and the paper sheets to be output is bent, even if the stack of paper sheets is tied together by a band Kj', for example, in a pigeon coop, In other words, the cohesive force of the strip can be brought to a value close to zero, and as a result, the paper *S can be pulled out without the strip sticking.

Therefore, it is possible to eliminate the band breaking work, and it is possible to obtain something that contributes to labor saving. In addition, the concavity of the curved laminate
Since it uses a rotary transfer and unloading mechanism with a convex curved outer peripheral surface that corresponds to the surface, the outermost paper sheets can be brought into close contact with the outer peripheral surface of the rotary speed retrieval mechanism. As a result, a stable feed function can be achieved.

The following is true! Examples will be described with reference to the drawings.

When driven, the rolling luna i) J rotates, and as the rolling luna and toro move up and down as a result of this rotation, the paper sheet holding table 1 is controlled to move up and down.

The above-mentioned paper sheet holder is formed of, for example, flat IK, and is horizontally provided to hold a plurality of mK paper QO laminates in a stacked state. Above the table #O, the one placed on the paper sheet holding table 1 and located on the top layer of the good paper cables Q makes contact and sends out a self-off signal, and when it does not make contact, it sends an on signal. A position detector II# formed of a sending switch and a switch is provided, and the power of the motor 5 is controlled to be turned on and off by the output of this position detector -9. That is, when the OFF signal is sent from the position detector t, the power of the motor 6 is turned off, and when the ON signal is sent from the position detector 1I#, the power of the motor/- is turned off. The normal rotation side is turned on and the paper** holding table 8 is controlled to rise. As a result, the paper sheet 11Q located at the top layer is always held at a constant position.

Therefore, on the left side of the paper sheet holding table 80 in the figure, there is a holder for controlling the position of the left end side of the paper ** placed on the holding table 8.
The intake cylinder 1-, which is formed into a flat shape, is provided vertically. The upper end of this suction cylinder 10 is located at approximately the same height 1 as the paper 111Q located in the upper layer of the ore deposit, and is closed as a plate JJK.

In the plate JJK, suction holes 11 are formed in, for example, five rows and three columns. The lower end of the intake cylinder 1# in the figure is connected to an intake cylinder 4fK (not shown).

On the other hand, above the left end of the sheet holding table 10 in the drawing, there is a rotary tram J1, which constitutes the main body of the feeding device, with its axis oriented in a direction perpendicular to the plane of the paper, and driven by an arrow J along a drive mechanism (not shown).
They are arranged so that they are rotated continuously or intermittently in a non-uniform manner in the direction indicated by 4. This rotating drum J
3 is formed to have a width narrower than the width j of the paper 1111Q, as shown in FIG.
II is arranged so as to be located directly above the center of the left end in FIG. 2 of the holding table 1. -The outer circumferential surface of this rotary driver 5 11 is formed in a convex shape so that the center in the width direction forms an outgoing line sp 1+ , and suction hole groups 11m and 11b are formed in opposing parts of the circumferential wall, respectively. Inside the zero-rotation drum l1t), an intake nozzle 1- is provided in a stationary state with its opening close to the inner peripheral surface of the rotating drum IJ.
To the left of the rotating drum IJ in FIG. 2, a pair of upper and lower conveyor belts J7. Two pairs are provided in parallel so that they can move in a circular direction.

The conveyor belt 11 located on the upper side of each pair is connected to a rotating drum JJOMl! as shown in FIG. The rotating drum 11 installed in Both conveyor belts IF and Im are guide rollers IIO.
Polymerizes in position. Between the part from the upper belt (JFO pair cylinder j2 to IWf-ri1) and the lower belt 1# that opposes this, the layered belt is gradually Each belt forms a narrow V-shaped O-insertion opening 2J with a straight section extending over 4 hours.

Above the right end of the paper sheet holding table 1 in FIG.
This support member 31 is fixed to a frame JKII via a member 12, as shown in FIG. On both sides of the part of the support member 11 that faces the paper sheet holding stand JIK, there are mounted protrusions 14m, 74% of which are directed downward, and these protrusions 14a.

In 14bK, axes 11m and 11b are installed in the center facing the rolled screw 3 in parallel with the paper cable holding table aO, and the outer periphery of each of the axes si* and zzb is Rollers sea and xgb whose surfaces are made of a material having high frictional resistance, such as f, are mounted on the rollers 1 and 2. Note that the shortest distance between the rollers lem and R6b is set to be wider than the width I of the paper jlliQ, and the portion of the shortest distance is the top layer paper slip that sends an off signal from the position detector, so it is difficult to avoid blindness. ] It is set at a low position for drying. The rollers Igm and 81btK are coaxially connected to worm gears H@ and syb], and these worm gears Jya and ayb are connected to the worm wheel 14 g a

# on the outer periphery of the shaft J9, which is provided upward on the outside in the direction perpendicular to the plane of the paper (right end in the figure). It is worn.

Oh, the above-mentioned axis 1# company, the above-mentioned Shiefa, evening 14a.

14bK screwed member 40&*4abK is rotatably supported. The shaft J# is connected to the rotary shaft of a motor 440 fixed via the supporting member JJKII material 4J through a force, a cylinder 41, and an auxiliary shaft 42. The rotation speed is set to a value that allows the rollers Ig & 16b to be rotated at a faster circumferential speed (than the rising speed of the paper sheet holding table). t, the above 14
4 and the sweater 5 can be selectively stopped by an external operation, and the motor JK can be reverse controlled by an external operation.

Next, the operation of the device configured as above will be explained.

First, the printer 1 is controlled in reverse, and the sheet holding table 1 is lowered to the lowest position. In this state, a stack of paper sheets 9 bundled in the form of, for example, the typeface PK is placed on the holding table 1! Place multiple conveyor belts JF and J# as shown in the figure at arrow 11.
When the circulation is moved in the direction shown by , kI! Ten dotsum IJ
is rotated in the direction shown by arrow 14. In addition, the motor 44
Start rotating and switch motor I to normal rotation,
Furthermore, the intake system is activated.

In this state, since the position detection lII is not in contact with the paper sheet located on the top layer, the motor J rotates continuously in the forward direction, and as a result, the paper sheet holding table 1 gradually rises.
Then, when the paper sheet holding table 1 rises to a certain position, the paper *@Q located at the top layer comes into contact with the position detector 5Iic, so the mopi temporarily stops. On the other hand, since the rotating drum 11 is rotating in the direction of arrow 14, this rotating drum IJ
Each time the holes 11* and 151m pass through the front surface of the opening of the intake nozzle IC, a large suction force acts on the left end of the paper sheets Q located on the top layer, and as a result, the paper sheets Q located on the top layer Q is attracted to the surface of the drum IJ, moves to the left in FIG. 2 as the drum rotates 110 times, and opens the V-shaped insertion opening 2.
Transported into 1. Finally, the conveyor belt IF
, 18 and transported to the IIO location. When the paper sheet q positioned at the top layer, such as a grain, is fed out, the position detector is turned on, and as a result, the motor 1 rotates again and the paper sheet holding table 8 is raised. Then, when it comes into contact with the position detection 41# of the paper sheet Q# located on the top layer, it is turned off, the 1 mode aX stops, and the paper sheet Q# located on the top layer is turned off again.
IQ is adsorbed and sent to the rotating drum JJK in the same way as above)
Served. In this case, the suction operation of the suction hole 12 prevents so-called two-sheet feeding jl.

In this way, the stacked sheets 11Q are fed one after another, so that the sheets 11Q are bundled by the band P, and one sheet is taken from the bundle. In general, it is very difficult to feed the material one by one, so in the device of the present invention, the following steps are taken to facilitate the feeding.
That is, when the stacked body X rises as the sheet holding table 1 rises, the stacked body X is finally located at the top layer! The surfaces of the rollers Iga and Ifjb, which are parallel to the feeding direction and parallel to the stacking direction, come into contact with the outer surfaces of the rollers Iga and Ifjb. Four-
Since the parts of Iga and IgbO that come into contact with the laminate are moving in the same direction as the rising direction at a speed lower than the rising speed of the sheet holding table 8, the side surfaces of the laminate xO mentioned above are moved by the rollers. :Ig&, Igbli When raised, it becomes K. When this friction rises, only the side surfaces of the laminate XB tend to rise first, so the entire laminate Furthermore, the frictional resistance between the strip P and the papers Q located in the uppermost layer becomes extremely small. Furthermore, since the outer circumferential surface of the rotating rotary drum 11 that adsorbs and transfers the paper sheets 9 is formed in a convex shape such that the center in the width direction forms a line, the outer circumferential surface of the rotary drum IJ is Laura J#a#J#b
K, the stacked body X is bent into a concave shape along the surface of the uppermost paper sheet q'o; The suction power works effectively, making it easy to pull out paper sheets.)
As a result, the sheets are fed out one by one.
” In this way, both sides of the stacked paper*@Q are parallel to the feeding direction and parallel to the stacking direction. Due to the relationship that the frictional force increases in
The outer peripheral surface of the i-type Q is formed to be convex, and the nine co-rotating drums IJ attract it and transport it in a direction along the trough line of the concave curved surface.

Therefore, since the paper 1111116 is a laminate Xolt bundled by the band PK, the friction between the band P and each paper 1IIIIQ can be made very small due to the above-mentioned Wan-O shadow formation, and this concave shape Curved paper*mtc, the outer periphery W is shaped so that the rotating drum II, which has a convex shape, follows along it.
As a result, the rotating drum 110 effectively suctions the paper sheets, thereby making it possible to feed them out one by one. Asahi can improve efficiency and save labor.

In the above-mentioned nine-smile vagina example, use a pair of rollers to roll the paper l1.
I am trying to raise both sides of lIII, but
This is not limited to 1. Run and see Laura Jg
a, place a small roller below J#b above-mentioned
The rollers 1gm, 36b, and these small rollers and k are respectively provided in parallel with the rollers 1gm and 36b, and the rollers 1' and 1' are placed in parallel with each other by a passed belt.

Furthermore, the outer circumferential surface of the rotating drum JJ is formed into a convex curved surface over its entire circumference, but the present invention is not limited to this.
Only the outer periphery of the suction hole 11 of 1 is a convex curved surface, or as shown in FIGS. For example, a member 50 having a large coefficient of friction and having a curved surface shape.
Also, although the above explanation states that the paper sheets are fed out one by one after being bound by the band PK, there is no binding.

The present invention is also applied to paper stacks stacked on paper and set on a holding stand. can do.

As described in detail above, according to the present invention, the paper feeding method can contribute to improving the efficiency and saving labor in processing paper sheets.
We can provide delivery equipment.
