Description

DEVICE FOR PAYING OUT LAYERED OBJECTS AND METHOD OF PAYING OUT LAYERED OBJECTS

The present invention relates to a feeding device of a stacking object and a method of feeding a stacking object for feeding out one object such as a laminated sheet stacked by using an electrostatic attraction force (= coulomb force) one by one.

Examples of a stacking object feeding device for stacking a stack of bills, which is an example of a stacking object, include a picker roller for sending one sheet of paper money from a storage portion to an outlet, a feed roller for feeding one sheet of paper money from a storage portion, and a drawing roller. It is known in the prior art that a separation roller disposed opposite to and provided with a guide block having a plurality of inclined surfaces disposed so as to receive a rear end of the stacked banknote of the storage portion (see Patent Document 1, for example).

Moreover, the electrostatic adsorption belt (or "electrostatic holding belt") which electrostatically adsorbs paper by forming an electrode pattern in a belt and applying a voltage is known (for example, refer patent document 2 or patent document 3).

Japanese Patent Laid-Open Publication No. 08-26497 Japanese Patent Laid-Open No. 2002-46886 Japanese Patent Laid-Open No. 2005-319739

However, in the feeding device of the lamination object described in the Patent Document 1, a resin roller is used as a picker roller, an feeding roller, or a separation roller, and the rollers are rotated in a state in which these resin rollers are in contact with the banknote surface. It is structured to collect bank notes using contact pressure. That is, since the laminated paper laminated | stacked is extracted one by one by the contact roller system, there exists a subject listed below.

(1) The contact pressure from the resin roller is transmitted to the paper after the second sheet, and two or more sheets of paper may be simultaneously drawn out.

(2) If the paper is coated on both sides or end faces, the frictional resistance between the two sheets of paper that is in contact is high, and when the first paper is sent out, the paper after the second sheet is fed out by the high frictional resistance. The force acting as a force is generated, and simultaneous feeding of several sheets of paper occurs.

(3) The laminated paper laminated | stacked often has the electric charge between papers. By the presence of this electric charge, several sheets of paper stick to each other, and when the first paper is sent out, a force acting in the feeding direction of the second and subsequent sheets is generated, and simultaneous feeding of several sheets of paper occurs.

Therefore, in the contact roller method, since it is necessary to suppress simultaneous feeding to the minimum, it is not only limited to specific objects, such as paper with low frictional resistance, as a selectable object, but also specific objects, such as paper with low frictional resistance, as an object Even if it is selected, it cannot reach to reliably avoid the simultaneous feeding of several sheets of paper which originate in contact pressure, a charging charge, etc. In addition, the higher the feed rate is set, the more stable separation feeding effect is impaired, and thus there is a problem that the demand for speeding up the feed rate cannot be met.

In addition, the electrostatic adsorption belt of the said patent documents 2, 3 sets two fixed rollers in the conveyance path | route which sends a medium, such as a paper and a film which separated one by one previously, and is spread between these two fixed rollers, It only has a conveyance function of strongly electrostatic adsorption and conveyance of the medium. And even if an electrostatic adsorption belt is used instead of the resin roller, the electrostatic adsorption belt and the lamination object remain in contact with each other. For this reason, since a belt contact pressure becomes a structure which acts on a laminated object, several simultaneous feed | feed-out occurs like a contact roller system.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has a degree of freedom of selection of a wide range of objects, and ensures a stable separation and feeding function for feeding out a stacking object from the surface one by one, thereby speeding up the feeding speed. An object of the present invention is to provide a feeding device and a feeding method of a lamination object.

In order to achieve the above object, in the present invention, in the feeding device of the laminated object for separating the laminated object laminated on the receiving member from the object at the surface position one by one and fed to the object processing apparatus,

An electrostatic adsorption belt spanning the drive rollers and the driven rollers and covered with a plurality of electrodes with an insulating layer;

An electrostatic adsorption control circuit which is connected to the plurality of electrodes, induces surface polarization on the object surface by applying a voltage, and returns to the original state without surface polarization by blocking the applied voltage;

An object dispensing mechanism for dispensing the dispensing target object electrostatically adsorbed onto the belt holding surface of the electrostatic suction belt by belt rotation;

By adjusting the relative spacing of the belt holding surface and the lamination object, the belt holding surface and the lamination object are approached or contacted at the time of adsorption and the belt holding surface and the lamination object are separated from each other during feeding.

Characterized in having a.

Therefore, in the stacking object feeding apparatus of the present invention, at the time of electrostatic adsorption of the object, the belt holding surface and the stacking object are relatively approached or contacted by the relative gap adjusting mechanism so that only one feeding object is held by the surface polarization. Electrostatic adsorption on the surface. Then, at the time of dispensing the object, the belt holding surface and the lamination object are relatively separated from each other by the relative spacing adjustment mechanism in the state of electrostatic adsorption, so that one piece of feeding object is separated from the remaining stacking object, and one feeding object and the remaining object are It is fed out, maintaining the peeling effect with a laminated object.

That is, by employing an electrostatic adsorption belt, as long as surface polarization is induced, a wide range of objects can be electrostatically adsorbed like conductors, semiconductors, and insulators. And the relative spacing adjustment mechanism of a belt holding surface and a lamination | stacking object is employ | adopted. For this reason, when a belt holding surface and a lamination | stacking object approach or contact relatively at the time of electrostatic adsorption, the effect | action of one piece of feeding object reliably electrostatically adsorbs to a belt holding surface by surface polarization appears. In addition, by separating one feeding object electrostatically adsorbed at the time of feeding out from the remaining stacking objects, the influence of belt contact pressure, charging charge, etc., which causes simultaneous feeding, is eliminated, and a stable separating feeding effect appears.

As a result, it is possible to speed up the feeding speed by securing a stable separate feeding function for feeding out a stacking object from the surface one by one while having a wide range of freedom of selection of the target object.

FIG. 7 is a flowchart showing the flow of the feeding control process performed by the feeding controller 37 in the feeding device A1 of the stacking object of Example 1. FIG. Hereinafter, each step of FIG. 7 will be described.

In step S1-1, after the main switch 34 is operated ON, it is judged whether or not the feeding start switch 35 is turned on, and in the case of YES (feeding start switch ON), the flow proceeds to step S1-2, In the case of NO (injection start switch OFF), the determination of step S1-1 is repeated.

In step S1-2, the paper loading table 3 is moved to the raising step S1-3 by the paper loading table raising mechanism 5. In S1-3, the ground rough position detection sensor 4 determines whether the ground height has entered the predetermined rough height, and if YES, the process proceeds to step S2, and if NO, the process returns to step S1-2. Goes.

In step S2, the rotational link member 13 and the stopper plate 2 follow the determination that the ground height in step S1-3 has entered the predetermined outline height, or the non-detection of contact with the laminated paper in step S3. The command to give a command is outputted to the rotation motor 17 and the stopper plate drive motor 27, and it transfers to step S3.

On the other hand, the rotation link member 13 and the stopper plate 2 make the raised position an initial setting position at the time of standby.

In step S3, following the command output for lowering the rotational link member 13 and the stopper plate 2 in step S2, the switch signal from the contact start detecting switch 19 is switched from the ON signal to the OFF signal, and the contact is made. It is determined whether the switch signal from the end detection switch 20 is switched from the OFF signal to the ON signal. If YES (contact detection with the laminated paper), the flow advances to step S4-1, and NO (with the laminated paper). Contact non-detection), the process returns to step S2.

In step S4-1, following the contact detection determination with the laminated sheet P in step S3, a command for applying a voltage to the plurality of electrodes 28 is output, and the flow proceeds to step S4-2.

In step S4-2, it is determined whether the elapsed time after applying the voltage to the electrode is longer than the set predetermined time. If YES, the flow advances to step S5, and if NO, step S4-2 is repeated.

In step S5, following the determination that the adsorption setting time has elapsed in step S4-2 or the determination that the drive pulse number < the first set value in step S6, a command for raising the rotating link member 13 and the stopper plate 2 is given. It outputs to the rotation motor 17 and the stopper plate drive motor 27, and it transfers to step S6.

In step S6, following the command output which raises the rotation link member 13 and the stopper plate 2 in step S5, the number of the drive pulses which were output to the rotation motor 17 and the stopper plate drive motor 27 is a 1st set value. It is determined whether the rotation link member 13 and the stopper plate 2 reach the upper limit position or more. If YES (the number of driving pulses ≥ the first set value), the process proceeds to step S7, and NO (drive If the number of pulses < first set value) is returned to step S5.

In step S7, following the determination that the number of drive pulses ≥ the first set value in step S6, or the determination that the sensor 9b is not from OFF to ON, a command to stop the first pivoting link 13 and the stopper plate 2 is issued. It lowers and outputs the roller drive command which rotates the drive roller 7 to the feed drive motor 24, and it transfers to step S8.

In step S8, it is detected by the sensor 9b whether the paper has entered the feeding roller 9a, and if YES, the flow advances to step S9-1, and if NO, the flow returns to step S7.

In step S9-1, the rotation drive continuation command of the drive roller 7 is output, the command which cuts off the voltage application to the electrode 28 is output, and it transfers to step S9-2. Here, the paper enters the delivery roller 9a, and the paper is continuously fed by the delivery roller 9a which is rotationally driven by a rotation drive motor (not shown). At this time, since the linear speeds of the drive roller 7 and the delivery roller 9a are not necessarily the same, in order to reduce friction between the paper being fed and the belt holding surface 6a, the voltage applied to the electrode 28 is cut off. Then, the rotational drive of the drive roller 7 is continued.

In step S9-2, the sensor 9b detects whether or not the paper has exited the feeding roller 9a. If YES, the process advances to step S9-3, and if NO, step S9-2 is repeated.

In step S9-3, rotational drive of the drive roller 7 is stopped, and the flow proceeds to step S10.

In step S10, the dispatch destination count number n is obtained by adding 1 to the last dispatch destination count number n, and the process proceeds to step S11.

In step S11, following the calculation of the dispatch destination count n in step S10, it is determined whether or not the dispatch destination count n is equal to or greater than the set number of copies no, and when YES (n? If NO (n <no), the flow proceeds to step S1-2.

Here, the set number of sheets no is no = 1 (initial value) just by pressing the feeding start switch, and is set by the setting operation when the number of sheets setter 36 is set.

Next, the operation will be described.

First, the "principle of generation of electrostatic attraction by the electrostatic chuck and features of the electrostatic chuck" will be described. Next, the action of the feeding device A1 of the stacking object of Example 1 will be described.

[Principle of Generating Electrostatic Suction Force by Electrostatic Chuck and Features of Electrostatic Chuck]

8 is an explanatory diagram of a principle of generating an electrostatic attraction force by an electrostatic chuck. It is explanatory drawing of the characteristic which an object returns to an original state by interruption of the applied voltage which an electrostatic chuck has. It is explanatory drawing of the characteristic which does not suck surrounding dust at the time of the generation of the electrostatic attraction force which an electrostatic chuck has. Hereinafter, the principle of generating the electrostatic attraction force by the electrostatic chuck and the characteristics of the electrostatic chuck will be described based on FIGS. 8 to 10.

The electrostatic adsorption belt 6 used in Example 1 is an example of the "electrostatic chuck" which electrostatically adsorbs an object by a Coulomb force. The principle of generating the electrostatic attraction force by the "electrostatic chuck" is that, as shown in FIG. 8, when voltage is applied to the electrode, surface polarization is induced on the surface of the object. Here, negative surface polarization is induced at the surface portion of the object facing the electrode portion to which the positive voltage is applied. In addition, positive surface polarization is induced at the surface portion of the object facing the electrode portion to which the negative voltage is applied. An electrostatic field is formed between the electrode surface and the object surface by an arc-like flow from the positive electrode to the negative electrode, and the electrostatic adsorption force for adsorbing the object to the surface of the insulating layer is generated by the electrostatic field. Occurs.

The characteristic of this "electrostatic chuck" is as follows.

(1) It is a wide object.

That is, any of conductor, semiconductor, and insulator may be used as the object. Also, an object having a hole (such as a printed board having a hole) is also an object of electrostatic adsorption.

(2) Only one sheet of the uppermost layer is adsorbed from the lamination object.

That is, since the electrostatic adsorption force is generated by inducing surface polarization on the surface of the object, the electrostatic adsorption force is not applied to the laminated object after the second sheet.

(3) A uniform electrostatic attraction force acts on the entire surface of the object.

That is, the uniformity of the electrostatic attraction force is secured by arranging the positive electrode and the negative electrode alternately and in a well-balanced pattern shape in each direction. In addition, the uniformity of the electrostatic attraction force prevents wrinkles even when the object is thin.

(4) Don't charge the object.

That is, as shown in FIG. 9, when the applied voltage is induced by the surface polarization of the object by a low applied voltage, and the applied voltage is interrupted, the object returns to its original state.

(5) Do not suck the dust around.

That is, as shown in FIG. 10, although the surface electric potential arises in the surface which faces an insulating layer among objects, the back surface of an object becomes an electric potential. Therefore, the dust on the back side of the object is not sucked up.

[Deposit Method of Laminated Land]

FIG. 11 is an explanatory diagram showing a method for disposing a laminated paper by the feeding device A1 of the laminated object of Example 1, showing the waiting step of FIG. 11A, FIG. 11B showing the electrostatic adsorption step, and FIG. 11C showing the object separating step. 11D shows the peeling feeding step. Hereinafter, the method of feeding the laminated paper will be described based on FIG. 11.

The feeding method of the lamination object of Example 1 which separates the laminated paper P laminated | stacked on the paper accommodation tray 1 sequentially one by one from the paper of a surface position, and feeds it to the office equipment 9 which is an object processing apparatus is a lamination | stacking. As the feeding means of the paper P, the electrostatic adsorption belt 6 covered with the driving roller 7 and the driven roller 8 and covered with the insulating layer 29 is used. A step, an electrostatic adsorption step, an object separation step, and a peeling feeding step. Each step is described below.

(Standby phase)

In the waiting step, as shown in FIG. 11A, the voltage applied to the plurality of electrodes 28 is cut off, and the belt holding surface 6a of the electrostatic adsorption belt 6 and the laminated paper P are relatively inclined apart from each other. . At this time, the stopper plate 2 is set at the uppermost position.

(Electrostatic adsorption step)

In the electrostatic adsorption step, the belt holding surface 6a of the electrostatic adsorption belt 6 is swung downward from the inclined spaced position, thereby as shown in FIG. 11B, the belt holding surface 6a of the electrostatic adsorption belt 6 is moved. By contacting the laminated paper P and applying a voltage to the plurality of electrodes 28, only one feed sheet Pa is electrostatically adsorbed to the belt holding surface 6a by surface polarization. At this time, the stopper plate 2 is lowered to a lower position so as to avoid interference with the electrostatic adsorption belt 6.

(Object separation step)

In the object separation step, as shown in Fig. 11C, the feed holding paper (1) is rocked upward by swinging the belt holding surface 6a of the electrostatic adsorption belt 6 in the state in which the feeding paper Pa is electrostatically adsorbed. Pa is separated from the remaining laminated paper Pb at an inclined space with an inclination angle θ upward in the feeding direction and separated at the position of the boundary surface S. FIG. At this time, the stopper plate 2 is raised to the uppermost position again and returned.

(Peel-off dispensing step)

In the peeling feeding step, as shown in FIG. 11D, the driving roller 7 is rotated in a state in which the belt holding surface 6a of the electrostatic adsorption belt 6 is inclined apart from the remaining laminated paper Pb. By the continuous peeling action which occurs at the boundary surface S which keeps the inclination angle (theta) of one feed sheet Pa and the remaining laminated paper Pb, it is electrostatically suppressed to the belt holding surface 6a of the electrostatic adsorption belt 6 One feed sheet Pa adsorbed is fed while peeling from the remaining laminated sheet Pb. At this time, the stopper plate 2 is set to the uppermost position.

[Effect Control of Laminated Papers]

12 is an operation explanatory diagram showing the feeding control action of the laminated paper by the feeding device A1 of the stacking object of Example 1, FIG. 12A shows a waiting time, FIG. 12B shows a suction time, and FIG. 12C shows a feeding The start time is shown, and FIG. 12D shows feeding out. Hereinafter, the feeding control action of the laminated paper will be described based on FIGS. 7 and 12.

In the feeding control of the stacking object of the first embodiment, when the feeding start switch 35 is turned ON, the flow advances from step S1 to step S2 to step S3 in the flowchart of FIG. 7 until the determination is YES in step S3. The flow from step S2 to step S3 is repeated.

That is, at the position of the electrostatic adsorption belt 6 shown in FIG. 12A, the rotation link member 13 is lowered until the entire surface contact between the belt holding surface 6a and the uppermost ground surface of the laminated paper P is detected. The stopper plate 2 is then lowered.

Then, when the entire surface contact between the belt holding surface 6a and the uppermost ground surface of the laminated sheet P is detected, in the flowchart of FIG. 7, the process proceeds from step S3 to step S4, where the belt holding surface 6a and the laminated sheet are stacked. Application of voltage to the plurality of electrodes 28 starts from the point where the uppermost ground surface of P is in full contact.

That is, by applying voltage to the plurality of electrodes 28, as shown in FIG. 12B, a surface polarization occurs at one feed destination Pa by the electrostatic system from the belt holding surface 6a, thereby maintaining the belt. A potential difference arises between the surface 6a and one feed sheet Pa, and one feed sheet Pa is electrostatically adsorbed to the belt holding surface 6a by a strong and uniform force.

When the voltage application to the plurality of electrodes 28 is started, in the flowchart of FIG. 7, the process proceeds from step S4 to step S5 to step S6, and from step S6 to step S6 until it is determined to be YES in step S6. The flow which repeats is repeated, and the command which raises the rotation link member 13 and the stopper plate 2 is output.

That is, in the state which electrostatically attracted one feed sheet Pa to the belt holding surface 6a, as shown in FIG. 12C, by lifting the electrostatic adsorption belt 6 at an angle, the belt contact pressure is 2 It is not transmitted to the remaining laminated paper Pb after the first sheet.

In addition, even when charge adsorption occurs between the feed sheet Pa of the first sheet and the remaining stacked sheets Pb of the second sheet, the charged charge is attracted to the electrostatic field of the belt holding surface 6a. For this reason, the charging between the two sheets of paper under the electrostatic adsorption belt 6 moves between the electrostatic adsorption belt 6 and the first feed destination Pa, and immediately below the belt holding surface 6a, The charge adsorption between the two sheets of paper is released (see FIG. 11C). In this state, as shown in FIG. 12C, when the electrostatic adsorption belt 6 is lifted up, two sheets of paper immediately below the belt holding surface 6a are separated.

Then, when the lifting operation of the first sheet feeding destination Pa, which has been electrostatically adsorbed on the belt holding surface 6a, is completed, in the flowchart of FIG. The flow from step S7 to step S8 is repeated until it is determined as YES, and the roller drive command is output.

That is, the first sheet feed destination Pa, which has been electrostatically adsorbed to the belt holding surface 6a by the roller drive, is fed to the office equipment 9 which is the object processing apparatus, but in the state shown in Fig. 12C, the electrostatic adsorption belt When (6) is rotated, the tensile force is generated in the advancing direction of the belt holding surface 6a with respect to the first feed sheet Pa. This action force (= tensile force) is concentrated on the boundary surface S due to the presence of the inclination angle θ upward in the feeding direction when it is to be transmitted to the rear side of the feeding paper Pa. For this reason, during the feeding of the first sheet feeding destination Pa, as shown in FIG. 12D, in the boundary plane S, the feeding is sequentially performed in the boundary plane shape in which the inclination angle θ is maintained in the feeding direction. The paper Pa is drawn out, and the first sheet of paper Pa is peeled off from the second sheet of paper Pb (pilling). Therefore, even sheets having high surface friction, such as coated paper, can be reliably separated one by one.

As described above, in the first embodiment, the belt holding surface 6a of the electrostatic adsorption belt 6 is brought into contact with the uppermost layer surface of the laminated paper P to perform electrostatic adsorption, and then the belt contact pressure is released. The electrostatic adsorption belt 6 is lifted and tilted by the electrostatic adsorption belt operating mechanism 10 so as to form an inclination angle θ upward in the feeding direction with respect to (P) to save the filling.

That is, by employing the electrostatic adsorption belt 6, as long as surface polarization is induced, a wide range of objects can be electrostatically adsorbed like conductors, semiconductors, and insulators. And the electrostatic adsorption belt operating mechanism 10 which swings the belt holding surface 6a up and down with respect to the laminated paper P is employ | adopted. For this reason, when the belt holding surface 6a is brought into contact with the laminated paper P at the time of electrostatic adsorption, one feed sheet Pa is reliably electrostatically adsorbed on the belt holding surface 6a by surface polarization. . In addition, by discharging one feed sheet Pa electrostatically adsorbed at the time of feeding out from the remaining laminated paper Pb, the influence of belt contact pressure, charged charge, etc., which causes simultaneous feeding, is eliminated, and stable feeding out is performed. It works.

As described above, the stable separation and feeding effect can be achieved without affecting the height of the feeding rate, thereby meeting the demand for increasing the feeding rate. In Example 1, since feeding control is performed by voltage application control and motor drive control which trigger a switch signal, for example, as the rotational motor 17, the feeding drive motor 24, and the stopper plate driving motor 27, By using a servo motor with a high response speed, it is possible to speed up the feeding speed. On the other hand, since the rotation motor 17 and the stopper plate drive motor 27 perform the up and down operation at the same timing, they may be used as one common motor.

In Example 1, the electrostatic adsorption belt operation by the oscillation attached to the electrostatic adsorption belt 6 is provided as a relative gap adjusting mechanism for approaching or separating the belt holding surface 6a and the uppermost surface of the laminated sheet P from each other. The mechanism 10 is adopted.

Here, instead of the electrostatic adsorption belt operation mechanism 10, the lamination object operation mechanism by the vertical movement of the paper loading table 3 can also be used as a relative space | interval adjustment mechanism. However, in the case of the stacking object operating mechanism, for example, when the laminated sheet P is heavy in thousands, it is a burden on the drive system to move the paper stack 3 up and down at high speed.

On the other hand, in the case of the electrostatic adsorption belt operating mechanism 10 caused by the up and down oscillation of the first embodiment, the electrostatic adsorption belt 6 having a constant weight only needs to be rocked up and down. That is, compared with the case of the lamination object operating mechanism, the electrostatic adsorption belt operating mechanism 10 is effective in that the burden on the drive system is small and stable.

In the case of Example 1, when the electrostatic adsorption belt 6 is inclinedly spaced apart from the laminated paper P, the driven roller 8 will fall down by its own weight, and a link angle will be in the maximum angle state. do. In this state, by lowering the rotational link member 13, when the belt holding surface 6a around the driven roller 8 starts to contact the laminated paper P, the link angle is about to be small from the maximum angle. By detecting this, the start of contact with the laminated paper P of the belt holding surface 6a can be detected. Then, by further lowering the rotating link member 13, when the belt holding surface 6a is placed on the upper layer surface of the laminated sheet P as a whole, the link angle becomes the minimum angle. By detecting this, the front contact with the laminated paper P of the belt holding surface 6a can be detected.

That is, in the first embodiment, paying attention to the change in the link angle between the first rotating link 13a and the second rotating link 13b according to the contact situation, the stopper hole formed in the first rotating link 13a ( By setting the contact start detection switch 19 and the contact end detection switch 20 at positions circumferential to 13c and facing the roller shaft 8a of the driven roller 8 supported by the second rotational link 13b. The structure which detects that the belt holding surface 6a contacts the uppermost layer surface of laminated paper P is employ | adopted.

Here, as the contact detection means, for example, the gap between the belt holding surface 6a and the uppermost layer surface of the laminated paper P may be detected using a gap sensor, a displacement sensor, or the like. However, in the case where the sheet of laminated paper P is largely bent and deformed in an S shape or the like, accurate measurement may not be possible depending on the measurement site.

On the other hand, in Example 1, by adopting the contact start detection switch 19 and the contact end detection switch 20, the belt holding surface 6a is laminated with high accuracy regardless of the sheet deformation of the laminated paper P. It is possible to detect that the uppermost surface of (P) is in contact, and a switch having a low cost and high operational reliability and durability can be used as compared to a gap sensor.

In Example 1, at the time of adsorption shown in FIG. 12B, the electrostatic adsorption belt 6 contacts the feeding end area | region of laminated | multilayer paper P whole surface. At this time, if the stopper plate 2 is fixed, the stopper plate 2 and the electrostatic attraction belt 6 interfere with each other. In order to prevent this interference, it is set to lower the stopper plate 2 to the interference avoiding position at the time of adsorption.

On the other hand, during the feeding shown in Fig. 12D, the sheet feeding paper Pa is peeled off from the laminated sheet Pb after the second sheet by the peeling. At this time, the stopper plate 2 is higher than the ground of the laminated sheet Pb after the second sheet so that the laminated sheet Pb after the second sheet is stopped without moving in the feeding direction. It is set to.

As described above, in the first embodiment, the variable stopper mechanism 12 is disposed while the belt holding surface 6a is disposed at a position facing the feeding side end region of the laminated paper P capable of exhibiting high separation performance and peeling performance. By adopting this, the interference with the electrostatic adsorption belt 6 is avoided at the time of adsorption, and the lamination paper Pb after the 2nd sheet can be reliably prevented at the time of feeding.

Next, the effect is demonstrated.

In the feeding device A1 of the lamination object of Example 1, the effect enumerated below can be acquired.

(1) The laminated object [laminated paper P] laminated on the receiving member [paper receiving tray 1] is separated one by one from the object at the surface position and fed to the object processing apparatus [office equipment 9]. In the feeding device A1 of a lamination object, the electrostatic adsorption belt 6 which spans the drive roller 7 and the driven roller 8, and the several electrode 28 was coat | covered with the insulating layer 29, and the said An electrostatic adsorption control circuit 30 connected to the plurality of electrodes 28 to induce surface polarization on the object surface by applying voltage, and returning to the original state without surface polarization by blocking the applied voltage; The object feeding mechanism 11 which feeds the feeding object (feeding paper Pa) electrostatic-adsorbed to the belt holding surface 6a of the belt 6 by belt rotation, the said belt holding surface 6a, and the laminated object [ By adjusting the relative spacing of the laminated paper P, the belt holding surface 6a and the laminated object [red] at the time of adsorption are adjusted. It has a relative space | interval adjustment mechanism (electrostatic adsorption belt operation mechanism 10) which approaches or contact | connects the lamination paper P, and separates the belt holding surface 6a and the laminated object (lamination paper P) at the time of feeding out.

For this reason, it is possible to provide the feeding device A1 for the stacking object to speed up the feeding speed by securing a stable separate feeding function for feeding out the stacking object from the surface one by one while having a wide degree of freedom of selection of the target.

(2) The said relative spacing adjustment mechanism electrostatic adsorption which operates the belt holding surface 6a of the said electrostatic adsorption belt 6 up and down with respect to the said accommodation member (paper accommodation tray 1) set to the fixed position. It is a belt operation | movement mechanism 10, The said electrostatic adsorption belt operation mechanism 10 is a downward movement operation which makes the said belt holding surface 6a approach or contact with a laminated object (laminated paper P), One feeding object (feeding paper Pa) is electrostatically adsorbed to the belt holding surface 6a, and the one feeding object (feeding paper Pa) is laminated | stacked on the rest by the upward operation | movement as it is in this electrostatic adsorption state. It separates from [the remaining laminated paper Pb].

For this reason, compared with the case where the operation mechanism of a lamination | stacking object is used as a relative space | interval adjustment mechanism, the burden of a drive system becomes low and can be stabilized, and speed up of a feed rate and stabilization of a feed operation can be aimed at.

(3) The electrostatic adsorption belt operating mechanism 10 sets the rotation shaft CL at a position parallel to the roller shafts 7a and 8a of the rollers 7 and 8 and on the side opposite to the feeding direction. It is a mechanism which swings the belt holding surface 6a of the said electrostatic adsorption belt 6 up and down by the rotational link member 13 which rotatably supports the both ends of the said rollers 7 and 8. The belt holding surface 6a is inclinedly spaced from the stacking object (laminated paper P) by upward swing as it is while the feeding object (feeding paper Pa) is electrostatically adsorbed on the belt holding surface 6a. , One feeding object (feeding paper Pa) having an upward inclination angle θ in the feeding direction is separated from the remaining stacking objects (resting lamination paper Pb).

For this reason, one feeding object (feeding paper Pa) is separated from the remaining stacking object (rest laminating paper Pb), and the peeling effect is achieved by suppressing and peeling the action force generated between the two objects to a minimum during feeding. can do.

(4) The rotating link member 13 is rotatable about the rotating shaft CL and includes a first rotating link 13a for rotatably supporting the driving roller 7 and the driving roller ( A second pivotal link 13b rotatable about the roller shaft 7a of 7) and rotatably supporting the driven roller 8; and the first pivotal link 13a and the second pivotal link. It has an angle limiting structure (stopper hole 13c) which limits the link angle which the 1313b makes to within a set angle range, and the said electrostatic adsorption belt operation mechanism 10 is the said 1st rotation link 13a and the said 2nd Contact situation detection means (contact start detection switch 19), which detects the contact state between the belt holding surface 6a and the stacking object (laminated paper P) by the change of the link angle formed by the rotational link 13b. End detection switch 20).

For this reason, it is possible to detect that the belt holding surface 6a is in contact with the uppermost layer surface of the laminated paper P with high accuracy regardless of the sheet deformation of the laminated paper P, and it is low in cost and operation reliability compared to the displacement sensor or the like. However, a highly durable switch can be used.

(5) The electrostatic adsorption belt 6 is set so that the belt holding surface 6a is disposed at a position opposite to the end region on the feeding side of the stacking object (lamination paper P), and the accommodation member (paper accommodation). Tray 1] releases the stopper function at the position of the dispensing end of the lamination object (lamination paper P) at the time of electrostatic adsorption of the dispensing object (feeding paper Pa), at least from the start of dispensing the object. Until the completion | finish, it has the variable stopper mechanism 12 which exhibits the stopper function which interrupts | feeds out the remaining lamination | stacking object (rest lamination paper Pb).

For this reason, the lamination paper after 2nd sheet | seat at the time of feeding out is arrange | positioned at the position which can exhibit high separation performance or peeling performance, while avoiding interference with the electrostatic adsorption belt 6 at the time of adsorption. (Pb) can be reliably prevented from being fed.

(6) The lamination object is a lamination paper P laminated on the accommodation member (paper receiving tray 1), and the object processing apparatus is fixed to a piece of paper separated by one sheet from the lamination paper P. The office device 9 performs the processing.

For this reason, it is possible to provide the office equipment 9 that has a stable separation feeding function for reliably separating each sheet from the laminated paper P and feeding out paper, and meeting the high speed processing demand.

(7) The laminated object [laminated paper P] laminated on the receiving member [paper receiving tray 1] is separated one by one from the object at the surface position and fed to the object processing apparatus [office equipment 9]. In the feeding method of a lamination object, as a drawing means of a lamination object (lamination paper P), it spreads over the drive roller 7 and the driven roller 8, and the several electrode 28 turns into the insulating layer 29 A standby step of blocking the voltage applied to the plurality of electrodes 28 by using the coated electrostatic adsorption belt 6 and relatively separating the belt holding surface 6a from the stacking object (laminated paper P); By applying the voltage to the plurality of electrodes 28 by relatively approaching or contacting the belt holding surface 6a and the stacking object (lamination paper P), one feeding object (feeding paper) is produced by surface polarization. Electrostatic adsorption step of electrostatic adsorption only on the belt holding surface 6a, and the belt holding surface 6a; One object to be fed (feed paper Pa), which is relatively spaced apart from the object to be stacked (laminated paper P), and is electrostatically adsorbed on the belt holding surface 6a, from the other object to be laminated (the remaining laminated paper Pb). The belt holding surface 6a is rotated by the drive roller 7 while the object separating step of separating and the belt holding surface 6a and the laminated object (laminated paper P) are relatively separated from each other. It has a peeling feeding step which feeds | feeds out one feed object (feeding paper Pa) which is electrostatically adsorb | sucked to from the other laminated object (rest lamination paper Pb).

For this reason, it is possible to provide a method for extracting a laminated object that has a wide degree of freedom of selection of the target object and secures a stable separate feeding function for feeding the laminated object one by one from the surface, thereby increasing the feeding speed.

(8) In the standby step, the voltage applied to the plurality of electrodes 28 is cut off, and the belt holding surface 6a is inclined spaced apart from the stacking object (laminated paper P). The belt retaining surface 6a is brought into contact with the stacking object (laminated paper P) by swinging the belt retaining surface 6a downward, and a voltage is applied to the plurality of electrodes 28. By polarization, only one feeding object (feeding paper Pa) is electrostatically adsorbed onto the belt holding surface 6a, and the object separating step is performed as described above as it is by electrostatically adsorbing one feeding object (feeding paper Pa). By swinging the belt holding surface 6a upward, one piece of feeding object (feeding paper Pa) is inclined spaced apart from the other stacking object (resting lamination paper Pb) with an inclination angle θ upward in the feeding direction. Separation, the peeling feeding step, the belt holding By rotating the drive roller 7 in a state in which 6a is inclinedly spaced from the remaining stacking object (remaining lamination paper Pb), one feeding object (feeding paper Pa) and the remaining stacking object (rest) are rotated. One feeding object (feeding paper Pa) electrostatically adsorbed on the belt holding surface 6a by the continuous peeling action generated at the boundary surface S holding the inclined angle θ of the laminated paper Pb]. Is extracted while peeling from the remaining lamination object (rest lamination paper Pb).

For this reason, the peeling effect which isolate | separates one feed object (feed paper Pa) from the remaining lamination | stacking object (rest lamination paper Pb), and suppresses the peeling force which generate | occur | produces between each object to a minimum during feeding is achieved. can do.

Example 2

Example 2 is an example using the lamination | stacking object operation mechanism which operates a lamination | stacking object up and down with respect to the electrostatic adsorption belt set to a fixed position as a relative spacing adjustment mechanism.

First, the configuration will be described.

FIG. 13 is an overall view schematically showing a feeding device A2 for the stacking object of Example 2. FIG. Hereinafter, the schematic structure of an apparatus is demonstrated based on FIG.

As shown in FIG. 13, the feeding device A2 of the stack object of the second embodiment has a paper accommodation tray 1 (receiving member), a paper stack 3, and a stack object operating mechanism 50 ( A relative gap adjusting mechanism), an electrostatic adsorption belt 6, a drive roller 7, a driven roller 8, an office device 9 (object processing apparatus), and a gap sensor 42. . On the other hand, in the paper receiving tray 1, a stopper plate portion 2 'is formed at the feeding portion of the paper.

As shown in FIG. 13, the stacking object operating mechanism 50 includes a paper stack 3 on which a stacking paper P (lamination object) is mounted on the electrostatic adsorption belt 6 set at a fixed position. ) Is a mechanism for operating in the vertical direction. The stacking object operating mechanism 50 electrostatically adsorbs one feed sheet Pa to the belt holding surface 6a by an upward operation of approaching or contacting the laminated sheet P with respect to the belt holding surface 6a. By the downward movement operation | movement as it is, the feed sheet Pa is isolate | separated from the remaining laminated paper Pb. On the other hand, the lamination object operation mechanism 50 has a lamination object drive motor 44 as a vertical drive actuator of the paper loading table 3 (refer FIG. 14).

The electrostatic attraction belt 6 spans the drive roller 7 and the driven roller 8, and the belt holding surface 6a is in a horizontal position at a position opposite to the end region on the feeding side of the laminated paper P. It is a feeding means of the laminated paper P fixedly arranged. By this electrostatic adsorption belt 6, the laminated paper P laminated | stacked on the paper accommodation tray 1 is separated one by one from the feeding paper Pa of a surface position, and the office equipment 9 which is an example of the object processing apparatus. To help.

The gap sensor 42 is provided in the paper accommodation tray 1, and the gap (gap) from the sensor setting position to the upper surface position of the laminated paper P is determined by the timing of the transmission of light waves or sound waves and the reception timing of reflected waves. Non-contact displacement amount detection means for detecting by time difference or the like.

FIG. 14 is a control block diagram showing a feeding control system in the feeding device A2 of the stacking object of Example 2. FIG. Hereinafter, the configuration of the feeding control system will be described based on FIG. 14.

As illustrated in FIG. 14, the feeding control system according to the second embodiment includes the main switch 34, the feeding start switch 35, the number setter 36, the gap sensor 42, and the sensor 9b. And the feeding controller 37, the motor driver 39, the feeding drive motor 24, the motor driver 43, the stacking object driving motor 44, the electrostatic adsorption control circuit 30, and the electrodes. 28 and a dedicated power supply 41 are provided.

The feeding controller 37 is set based on input information from the main switch 34, the feeding start switch 35, the number setter 36, the gap sensor 42, the sensor 9b, or the like. Operation processing is performed in accordance with the control program. The control command based on the calculation result is output to the motor drivers 39 and 43 and the electrostatic adsorption control circuit 30 to drive the control of the feeding drive motor 24 and the stacking object driving motor 44, and the electrode ( Control of voltage application and voltage application release to 28) is performed.

FIG. 15 is a flowchart showing the flow of the feeding control process executed by the feeding controller in the feeding device A2 of the stacking object of Example 2. FIG. Hereinafter, each step of FIG. 15 will be described.

In step S21, after the main switch 34 is operated ON, it is judged whether or not the feeding start switch 35 is turned on, and in the case of YES (feeding start switch ON), the flow advances to step S22 and NO (feeding start). If the switch is OFF), the determination of step S21 is repeated.

In step S22, following the judgment of the starting start switch ON in step S21, the determination of Ga> Gao in step S23, or the determination of n <no in step S29, a driving command for raising the laminated paper P is laminated. It outputs to the object drive motor 44, and it transfers to step S23.

In step S23, following the rising command output of the laminated sheet P in step S22, the gap value Ga detected by the gap sensor 42 sets the feed sheet Pa to the set value Gao (belt holding surface 6a). Value of the sub-mm unit that can be electrostatically adsorbed or not], and if YES (Ga &lt; Gao), the process proceeds to step S24, and if NO (Ga &gt; Gao), the process returns to step S22.

In step S24, following the determination of Ga≤Gao in step S23, a command for applying a voltage to the plurality of electrodes 28 is output, and a drive command for lowering the laminated paper P by a predetermined amount is issued. It outputs to 44, and it transfers to step S25.

In step S25, following the determination that the output of the drive command for lowering the laminated paper P in step S24 or the number of drive pulses in step S26 &lt; the third set value, the roller drive command is issued to the feeding drive motor 24. The output then proceeds to step S26.

In step S26, following the output of the roller drive command in step S25, the number of drive pulses output to the feeding drive motor 24 is equal to or greater than the third set value (the value corresponding to the time at which the feeding destination Pa is completed). In the case of YES (number of driving pulses ≥ third set value), the process proceeds to step S27, and when NO (number of driving pulses <third set value), the process returns to step S25.

In step S27, following the stop of driving of the driving roller 7 at the determination of the number of drive pulses ≥ the third set value in step S26, a command for interrupting the application of voltage to the electrode 28 is output, and the flow proceeds to step S28.

In step S28, following the interruption of the voltage application to the electrode 28 in step S27, the number of dispatch destination counts n is added to 1 by the previous dispatch destination count number n, and the process proceeds to step S29.

In step S29, following the calculation of the dispatch destination count n in step S28, it is determined whether the dispatch destination count n is greater than or equal to the set number of copies no, and when YES (n? If NO (n <no), the flow returns to step S22.

Here, the set number of sheets no is no = 1 (initial value) just by pressing the feeding start switch, and is a value by a setting operation when set by the number setter 36.

In addition, since another structure is the same as that of Example 1, the same code | symbol is attached | subjected to a corresponding structure and description is abbreviate | omitted.

Next, the operation will be described.

FIG. 16 is an explanatory diagram showing a method of dispensing laminated paper by the feeding device A2 of the laminated object of Example 2, FIG. 16A shows a waiting step, FIG. 16B shows an electrostatic adsorption step, and FIG. 16C shows an object separation. 16D shows the peeling aid step. Hereinafter, the method of feeding the laminated paper will be described based on FIG. 16.

The feeding method of the lamination object of Example 2 which separates the laminated paper P laminated | stacked on the paper accommodation tray 1 sequentially from the paper of the surface position one by one, and feeds it to the office equipment 9 which is an object processing apparatus is a lamination | stacking. It is implemented by using the electrostatic adsorption belt 6 which spread | covers the drive roller 7 and the driven roller 8, and the some electrode 28 was coat | covered with the insulating layer 29 as a feeding means of the paper P. Similarly to Example 1, there are a standby step, an electrostatic adsorption step, an object separation step, and a peeling feeding step. Each step is described below.

(Standby phase)

As shown in FIG. 16A, the waiting step interrupts the voltage applied to the plurality of electrodes 28 and is parallel to the belt holding surface 6a with respect to the belt holding surface 6a of the electrostatic adsorption belt 6. The upper surface of the laminated paper P is spaced apart.

(Electrostatic adsorption step)

The electrostatic adsorption step is performed by the upward movement of the laminated paper P which lifts the upper surface of the laminated paper P parallel to the belt holding surface 6a with respect to the belt holding surface 6a of the electrostatic adsorption belt 6. As shown in FIG. 16B, the upper surface of the laminated paper P approaches or contacts the belt holding surface 6a of the electrostatic adsorption belt 6, and a voltage is applied to the plurality of electrodes 28. Due to polarization, only one feed sheet Pa is electrostatically adsorbed to the belt holding surface 6a.

That is, when the feeding start switch 35 is turned ON, the flow proceeds from step S21 to step S22 to step S23 in the flowchart of FIG. 15, and from step S22 to step S23 while the gap value Ga exceeds the set value Gao. The advancing flow is repeated to bring the upper surface of the laminated paper P closer to the belt holding surface 6a of the electrostatic adsorption belt 6. When the gap value Ga becomes less than or equal to the set value Gao, the flow advances from step S23 to step S24, where voltage is applied to the plurality of electrodes 28.

(Object separation step)

In the object separation step, the laminated paper P is parallel to the belt holding surface 6a with respect to the belt holding surface 6a of the electrostatic adsorption belt 6 as it is in the state where one feed sheet Pa is electrostatically adsorbed. By the downward movement of the laminated paper P which lowers the upper surface, as shown in FIG. 16C, one feed sheet Pa is isolate | separated from the remaining laminated paper Pb.

That is, when the gap value Ga becomes less than or equal to the set value Gao, in the flowchart of FIG. 15, the process proceeds from step S23 to step S24 to output a command for applying a voltage to the plurality of electrodes 28, and to form the laminated paper P. A driving command to lower is output, and one feed sheet Pa is adsorbed, and one feed sheet Pa is separated from the remaining stacked sheets Pb.

(Peel-off dispensing step)

The peeling feeding step is shown in FIG. 16D by the rotation of the drive roller 7 in a state where the remaining laminated paper Pb is spaced in parallel with respect to the belt holding surface 6a of the electrostatic adsorption belt 6. Similarly, one feed sheet Pa is electrostatically adsorbed to the belt holding surface 6a of the electrostatic adsorption belt 6 by the continuous peeling action generated between the feed sheet Pa and the remaining laminated sheet Pb. Is extracted while peeling from the remaining laminated paper Pb.

That is, in the flowchart of FIG. 15, the process proceeds from step S24 to step S25, in step S25, the roller driving command is output, and voltages are supplied to the plurality of electrodes 28 until the feeding completion condition of step S26 is satisfied. The roller drive command is output while maintaining the application. In addition, since another operation is the same as that of Example 1, description is abbreviate | omitted.

Next, the effect is demonstrated.

In the feeding device A2 of the lamination object of Example 2, the following effects can be obtained in addition to the effects of (1), (6) and (7) of Example 1.

(9) The said relative spacing adjustment mechanism is the laminated object operation mechanism 50 which operates the said laminated object (laminated paper P) up and down with respect to the said electrostatic adsorption belt 6 set to the fixed position, The said The stacking object operating mechanism 50 belts one feeding object (feeding paper Pa) by an upward operation of approaching or contacting the stacking object (laminated paper P) with respect to the belt holding surface 6a. Electrostatic adsorption is carried out to the holding surface 6a, and one feed object (feed paper Pa) is isolate | separated from the remaining laminated object (rest lamination paper Pb) by the downward operation | movement as it is in this electrostatic adsorption state.

For this reason, by the fixed installation of the electrostatic adsorption belt 6, the ease of belt drive and the ease of voltage application can be aimed at. In particular, it is useful when the number of the stacking objects of the stacking object is small and the drive system burden of the stacking object operation mechanism 50 is low.

Example 3

Example 3 is a modification which made the rotation link member the structure by roller support different from the rotation link member of Example 1. FIG.

First, the configuration will be described.

FIG. 17 is an explanatory view showing the feeding control action of the laminated paper by the feeding device A3 of the stacking object of Example 3, FIG. 17A shows a waiting time, FIG. 17B shows a suction time, and FIG. 17C shows a feeding A start time is shown, and FIG. 17D shows a feeding out. Hereinafter, the structure of the rotation link member 13 of Example 3 is demonstrated based on FIG.

The rotation link member 13 of Example 3 is attached to the 3rd rotation link 13d which can be rotated centering on the rotation shaft CL, and the link shaft 13f provided in the edge part of the 3rd rotation link 13d. To the fourth rotating link 13e and the third rotating link 13d, which are rotatable relative to each other and rotatably support the driving roller 7 and the driven roller 8 by the roller shafts 7a and 8a. Is opened in a circular arc shape in the first stopper hole 13g (angle limiting structure) through which the roller shaft 7a of the drive roller 7 is inserted, and the third pivoting link 13d. The roller shaft 8a of 8 has the 2nd stopper hole 13h (angle limitation structure) which penetrates.

And the belt holding surface 6a by the change of the link angle which the 3rd rotation link 13d and the 4th rotation link 13e make in the position which faces the 2nd stopper hole 13h of the 3rd rotation link 13d. ) And a contact start detection switch 19 (contact condition detection means) for detecting the contact state between the laminated paper P and the laminated paper P, and the contact end detection switch 20 (contact condition detection means) are provided.

In addition, since another structure is the same as that of Example 1, the same code | symbol is attached | subjected to a corresponding structure and description is abbreviate | omitted.

Next, the operation will be described.

In the case of Example 3, as shown in FIG. 17A, when the electrostatic adsorption belt 6 is inclinedly spaced apart from the laminated paper P, the drive roller 7 and the driven roller 8 are based on its own weight. Drooped down, the link angle is at its maximum angle. In this state, by lowering the rotational link member 13, when the belt holding surface 6a around the driven roller 8 starts to contact the laminated paper P, the link angle is about to be small from the maximum angle. By detecting this, the start of contact with the laminated paper P of the belt holding surface 6a can be detected. Then, by further lowering the rotating link member 13, when the belt holding surface 6a is placed on the entire upper surface of the laminated sheet P, the link angle becomes the minimum angle as shown in Fig. 17B. By detecting this, the front contact with the laminated paper P of the belt holding surface 6a can be detected.

And when full contact with the laminated paper P of the belt holding surface 6a is detected, as shown to FIG. 17C and FIG. 17D, the drive roller 7 and the driven roller 8 will add to the total weight. As a result, the tilt angle θ is held upward in the feeding direction stably when the vibration is input from the outside or the drive system. For this reason, at the time of the vibration input by high speed feeding etc., one feed sheet Pa can be isolate | separated and fed by high stability. In addition, since another operation is the same as that of Example 1, description is abbreviate | omitted.

Next, the effect is demonstrated.

In the feeding device A3 of the lamination object of Example 3, in addition to the effects of (1) to (3) and (5) to (8) of Example 1, the following effects can be obtained.

(10) The rotating link member 13 includes a third rotating link 13d that can rotate around the rotating shaft CL, and a link shaft 13f provided at an end of the third rotating link 13d. ), A fourth rotational link 13e rotatably supporting the drive roller 7 and the driven roller 8, and the third rotational link 13d and the fourth rotational link 13e. Has an angle limiting structure (first stopper hole 13g, second stopper hole 13h) that restricts the link angle formed by &lt; Desc / Clms Page number 6 &gt; within a set angle range, and the electrostatic adsorption belt operating mechanism 10 rotates the third rotation. Contact situation detection means (contact) for detecting a contact situation between the belt holding surface 6a and the stacking object (laminated paper P) by a change in the link angle formed by the link 13d and the fourth rotational link 13e. Start detection switch 19, contact end detection switch 20].

For this reason, it is possible to detect that the belt holding surface 6a is in contact with the uppermost layer surface of the laminated paper P with high precision regardless of the sheet deformation of the laminated paper P. In addition, a switch having high durability can be used, and the self-feeding weight of the drive roller 7 and the driven roller 8 together can ensure a stable feeding operation against vibration input and the like.

The example of the lamination | stacking object operation mechanism 50 which operates the lamination | stacking object side up and down was shown. However, the relative gap adjusting mechanism may be an example in which both the belt holding surface and the stacking object are operated. In addition, in the case of the electrostatic adsorption belt operating mechanism 10, an example of a mechanism that swings up and down is shown, but it is an example of a mechanism that moves up and down in parallel, or a mechanism that moves up and down in accordance with an operation trajectory appropriately determined according to each step. Also good.

In Example 1, 3, the example by the contact start detection switch 19 and the contact end detection switch 20 which were provided in the position of the angle restriction structure of two rotational links as the contact state detection means was shown. However, the rotation angle sensor which detects the angle of two rotation links, the roller position sensor which detects the position of the roller supported by two rotation links, etc. may be used as an example.

In Examples 1-3, the example which laminated | stacked the laminated object laminated | stacked on the accommodating member sequentially one by one from the object of an upper surface position, and fed it to the object processing apparatus was shown. However, if the laminated object laminated | stacked on the accommodating member is carried out, you may separate one by one from the object of a position, and feed it to the object processing apparatus.
