CONSTITUTION:A position of a presser roller 13 is set to cardboard 1A, and the stacked cardboard 1A are turned to the front face to be loaded onto an elevator H for a sheet-like matter to be measured of a supplying device A for a sheet-like matter to be measured. The elevator H for a sheet-like matter to be measured is lifted with the stacked cardboard so as to bring the cardboard 1A close to the presser roller 13 and a pulling-out roller 16. In this condition, there is little gap between the presser roller 13 and the pulling-out roller 16. When this condition is carried out, suction force of a suction means J for a sheet-like matter to be measured works so as to suck the cardboard 1A at the upper most level so that the cardboard 1A touches the presser roller 13 and the pulling-out roller 16 and advances at the same time to be fed to a pulling-in roller 23. Then the cardboard is bitten to be sent out.

Description

Detailed Description of the Invention

[0001]

INDUSTRIAL APPLICABILITY The present invention can reliably take out relatively thick sheet-like objects to be measured one by one, such as cardboard for paper cases and plastic cards such as cash cards and prepaid cards. The present invention relates to a method and apparatus for supplying a measured sheet-like material.

[0002]

2. Description of the Related Art An example of a thick paper feeding device (A ') used in a conventional thick paper printing state inspection / sorting device will be described.
FIG. 18 is a front view of a conventional cardboard feeder (A '), which is a stacking unit (41).
Is for stacking and stacking a large number of thick papers (1), and the thick papers (1) are piled up along the stacking guide (42). The lower end of the stacking guide (42) is formed in an arc shape, and the thick paper (1)
The lower layer of the stack is designed to be stacked in an arc, and the paper feed belt (46) installed at the bottom of the stacking guide (42).
The bottom cardboard (1) is pulled out one by one.

Reference numeral (44) is a cardboard which is obtained by lifting the rear end of the cardboard (1).
It is an end lifting mechanism that makes it easier to pull out (1) one by one. The loading guide (42) can be raised and lowered freely
The gap through which the thick paper (1) passes can be adjusted according to the thickness of (1). The paper feed tray (45) connected to the transport section (B) has a wide paper feed belt (46) stretched between two front and rear main drive shafts (47), and an auxiliary roller (43). Supported by. The thick papers (1) taken out one by one are mounted on a wide paper feed belt (46) and supplied to the transport section (B).

The problem with such a cardboard feeding device (A ') is that the bottom cardboard (1) is slid out only one sheet and pulled out, so that the second cardboard is used.
If there is no gap between (1x) and the bottom cardboard (1) is slid, the pressure between the second cardboard (1) will be reduced and the second cardboard (1) will also be at the bottom. There is a problem in that the cardboard (1) is attached to the cardboard (1) to move and the cardboard (1) is erroneously fed.
In addition, since the bottommost cardboard (1) laminated in this way is pulled out, it will rub against the second cardboard (1), and due to the generation of static electricity, the two cardboards (1) may become stronger in some cases. It is conceivable that a take-out error may occur when trying to attach and move.

Therefore, if the clearance between the stacking guide (42) and the paper feed belt (46) is adjusted so that only the uppermost thick paper (1) can pass, the clearance adjustment becomes extremely difficult, and the adjustment is time-consuming. However, if the gap is made too small, the printed surface of the sheet-like object to be measured (1) pulled out through the gap may be scratched, causing defective cardboard at the take-out portion.

[0006]

The problems to be solved by the present invention are as follows.
It is possible to separate one by one before taking out the sheet to be measured such as cardboard or plastic card, and to minimize the contact between the sheet to be measured to be taken out and the sheet to be measured adjacent to it. Make sure that you can take out the sheets one by one with certainty, and that when you take out the sheet-like object to be measured, almost no load is applied to the sheet-like object to be measured, and especially the printed surface of the sheet-like object to be measured has scratches. The thing is that you don't put things on.

[0007]

[Means for Solving the Problems] In order to solve the above-mentioned problems, a method for supplying a sheet-like object to be measured according to the present invention is as follows. The sheet to be measured (F), and then the sheet-to-be-measured (1) is taken out one by one at the sheet-to-be-measured (F) to be measured, and the sheet-to-be-measured is measured in the next step. Object (1) 1
In the method of supplying the sheet-like material to be measured that supplies one by one, the sheet-like material (1) to be measured at the uppermost stage is sucked from above and the sheet-like material (1) to be measured at the uppermost stage is the second object to be measured. The sheet-like object (1x) is separated from the sheet-like object (1x), and the sheet-like object to be measured (I) to be measured is brought into contact with the upper surface of the uppermost sheet-like object to be measured (1) to be sent out.

[0008] In this way, the sheets to be measured are laminated.
Since the uppermost one of (1) is sucked, a gap (K) is formed between the second sheet to be measured (1x) and the sheet to be measured (1) in the uppermost row is pulled out. Even in such a case, the space between the measured sheet-like materials (1) is not in a depressurized state, and only the uppermost measured sheet-like material (1) is not taken out and an error in taking out does not occur. Further, upon taking out, the uppermost sheet-like object to be measured (1) does not rub against the second sheet-like object to be measured (1), and static electricity is not generated. Further, since there is no stacking guide (42) as in the conventional example, there is no need to adjust the gap between the sheet feeding belt (46) and the stacking guide (42) to remove the sheet-like object (1) to be measured. The printed surface of the sheet-like object (1) to be measured is not scratched, and the occurrence of defects due to removal is eliminated. Therefore, according to the method of the present invention, not only the measured sheet-like objects (1) can be separated and can be taken out one by one, but also when the measured sheet-like objects (1) are taken out. There is an advantage that a load is hardly applied to the measured sheet material (1) and the printed surface of the measured sheet material (1) is not scratched.

A second aspect is a further improvement of the method according to the first aspect, in which the whole laminated sheet-like object to be measured (1) is moved in the laminating direction and supplied to the sheet-like object taking-out portion (F) to be measured. Then, the measured sheet material (1) is taken out one by one at the measured sheet material extraction section (F), and the measured sheet material (1) is transferred to the next step.
In the method of supplying the measured sheet-like materials one by one, the air is blown toward the laminated surface of the measured sheet-like material (1) to supply air between the measured sheet-like materials (1) The separated air promotes the separation of the sheet material (1) to be measured, and the sheet material (1) to be measured at the uppermost stage is sucked from above to attach the sheet material (1) to be measured to the second sheet. Measuring sheet (1x)
The uppermost sheet to be measured that has been pulled from and sucked

And a suction means (J) arranged above the stacked sheet-like objects to be measured (1) (1x) for sucking the uppermost sheet-like object to be measured (1), and the laminated sheet-like objects to be measured (J). It is arranged above the object (1) and consists of the measured sheet-like material conveying means (I) that sends out the measured sheet-like material (1) by contacting the upper surface of the sucked measured sheet-like object (1). It is characterized by being done.

A fourth aspect is an embodiment of the method of the second aspect, in which the stacked sheet-like objects to be measured (1) (1x) ... are moved in the stacking direction to take out the sheet-like object to be measured (F). ) To be measured sheet-like material (1) for supplying the measured sheet-like material (1)
And a suction means arranged above the stacked sheet-like objects to be measured (1) and sucking the uppermost sheet-like objects to be measured (1).

Only (1A) is accurately bitten and sent out. The amount by which the front end lifting block (27c) is pushed down {= the sheet-shaped object passing gap (t)} is regulated by the lifting nut (27h) contacting the link support base (27f). The second cardboard (1A) is usually the front edge fixed frame
It has hit (27b) and is blocked from moving forward.

Regarding removal of the uppermost thick paper (1A), when the uppermost thick paper (1A) is sucked as described above, the uppermost thick paper (1A) and the second thick paper (1A) Gap between (K)
Top cardboard (1A) sliding to form
There is no pressure reduction between the 2nd thick paper (1A) and the 2nd thick paper (1A), and there is no possibility that they will come into surface contact and generate static electricity, and will not stick to each other. It is done. In this case, if the air is positively supplied to the gap (K) by the measured sheet material separating means (L), the separation will be more complete.

Cardboard advanced by feeding cardboard (1A)
The front end of (1A) is followed by transfer roller (24a) (24b) and drive roller.
It will be bitten between (3) and transferred to the transfer section (B), and will move in the direction of the inspection device (C). Here, at the time of transfer to the transport section (B), the printing side surface of the thick paper (1A) is cleaned of dust by the air blow (43) and the brush roller (40), and then the thick paper (1A). Ends of pinch roller (2) and drive roller (3)
It is bitten in between and is sent out forward on the mounting plate (10). The feed rate is accurately feedback controlled by the signal from the rotary encoder. Drive roller
Since the feed speed of (3) is faster than the feed speed of the sheet material feeder (A) to be measured, if the thick paper (1A) is caught between the pinch roller (2) and the drive roller (3), the one-way clutch (OW)
By this function, the group of rollers constituting the sheet-like object-to-be-measured conveying means (I) idles. This will ensure that cardboard (1
A) will be sent out from the transport section (B).

Since the pinch roller (2) is attached slightly obliquely to the reference guide roller (11) as described above, the thick paper (1A) sandwiched between the pinch roller (2) and the drive roller (3). Is the reference guide roller by the pinch roller (2).
The thick paper (1A) is pressed toward (11), and the reference side (1a) of the thick paper (1A) advances along the reference guide roller (11). The reference side (1a) of the advancing cardboard (1A) has a pinch roller (2) and a drive roller densely arranged at regular intervals.
It is sandwiched between (3) and one after another and moves forward at a constant speed. The pinching force between the pinch roller (2) and the driving roller (3) is always kept constant by the tension of the tension spring (21).

The cardboard (1A) under the camera (31) at a constant speed
When the sheet passes, the fiber sensor (not shown) first detects the leading edge of the thick paper (1A), and from that point on, the linear array image sensor connected to the camera (31) detects the thick paper to be inspected. The prints of (1A) are read one after another and compared with the values read in the reference pattern, and if the newly read signals match at all points, it is judged as a good product, and as a good product ) Is sent to.

Thick paper (1A) sent to the sorting paper discharge section (D)
Moves under the suction housing (50) whose bottom surface is open while advancing along the paper discharge roller (35). At this time, since the inside of the suction housing (50) is in a depressurized state, the thick paper (1A) is adsorbed and moved forward. If the thick paper (1A) is defective, a sensor (not shown) detects that it has just moved to the lower side of the paper elevating / lowering frame (54). ), The elevating means (58) is operated to separate the thick paper (1A) from the paper discharge roller (35). Cardboard
If (1A) is removed from the paper discharge roller (35) even a little, the suction action of the suction housing (50) will suddenly decrease, and it will drop as it is.
As described above, it falls into the guide frame (59), then fits into the defective product storage frame (64a) on the defective product storage base (64), and is sequentially stacked. Defective product storage (64) is initially a lifting cylinder
It has been lifted by (65), the upper part of the defective product storage base (64) fits in the guide frame (59), and the crosspiece (55) fits in the upward notches (61) (64b) of both. It is designed so that the cardboard (1A) can be accurately inserted into the defective product storage frame (64a) by jamming. The defective product storage base (64) is of an elevator type, and the defective product storage base (64) is gradually lowered as the defective products (1) are accumulated. The paper discharge roller (35) is
As shown in the figure, the chain is constantly driven by the paper discharge drive motor (52).

When the thick paper (1A) sent to the sorting paper discharge section (D) is a good product, it is adsorbed on the lower surface of the suction housing (50) and passes through the paper discharge roller (35) to pass the defective product storage table (64). ) Is dropped into a non-defective item storage table (63) prepared on the downstream side, and sequentially stacked. The non-defective item storage base (63) is also an elevator type, and as the non-defective item (1) accumulates, the non-defective item storage table (63) gradually lowers, and a certain amount of non-defective item cardboard (1A)
When the sheets are stacked, the entire apparatus is stopped, the stacked cardboard (1A) is taken out, and the non-defective item storage table (63) is raised, and then the work is restarted.

On the other hand, in the device for supplying sheet material to be measured (A), when all the stacked thick papers (1A) are sent out, the device stops and the table for measuring sheet material (H) descends, Supply thick paper (1A) to restart the work. The presence or absence of the thick paper (1A) is detected by the measured sheet-like object detector (28).

18 to 21 show another embodiment of the sheet-like object supplying device (A) to be measured, which is applied to a plastic card (1B). Although the basic idea is the same, the pressing roller (13) and the drawing roller (16) are arranged in one suction means (J) whose inside is decompressed by the lower surface opening, and the drawing motor (16c) It is driven by a belt.
This is because it is not necessary to move the pressing roller (13) back and forth in the case of plastic (1B) because the length is short.

The measured sheet-shaped object guide portion (EB) for the plastic sheet (1B) is slightly different in structure from the measured sheet-shaped object guide portion (EA) for the thick paper (1A), but the basic idea Are the same. In this case, the front end guide plate (27a) of the measured sheet guide (EA) for thick paper (1A), the front end fixing frame
(27b), front end guide lifting block (27c), front end guide link mechanism (27d), lifting screw (27e), link support base (27f), link spring (27g), etc. It is only installed along the front end of 1B), and antistatic air containing discharge ions is blown from the picker (27A) between the plastic cards (1B).

The picker (27A) will be described in detail. The picker (27A) includes the picker body (27A1) and the air supply block.
(27A2) and. (It goes without saying that they may be integrally molded.) The picker body (27A1) is a prismatic shape, leaving a part at the upper end of the card facing surface (27B).
A corner cutout (27C) is formed, and three air blowout holes (27D) communicating with this inclined surface have picker bodies (27A1).
Is drilled diagonally upward. The tip of the card (1B) is in contact with the residual portion (27E) sandwiched by the notches (27C). (The number of air blowing holes (27D) is not limited to three.) Picker body (27A1) and pull-out roller (1
The gap with 6) is set so that only one plastic card (1B) can pass through. Plastic card (1
The lift (Li) of B) is slightly lowered forward (in Fig. 18, the inclination angle is α
Indicate. ) Is formed on the plastic card (1B)
Lift in a state of falling forward. As a result, blown-in air containing ions and the plastic card (1B) described later
It is easier to lift and separate.

The air supply block (27A2) is integrally bolted to the picker body (27A1), and the air supply hole (27F) bored inside is the air blowout hole (27D).
It is designed to communicate with. As the supplied air, dry clean air containing discharge ions is used. This allows air and plastic cards to normally flow in.
By friction with (1B), static electricity is generated on the surface of the plastic card (1B), but in this case, since discharge ions are included, the generation of static electricity is suppressed and the card (1B) is completely separated.

Then, as shown in FIG. 18, the picker (2
(7A) blows ion-containing air between the plastic cards (1B) to separate them, and the topmost plastic card (1B) is sucked using the suction force of the sheet material suction means (J) to be measured, and then held down. Contact the roller (13) and the pull-out roller (16). Since the pull-out roller (16) is rotating, it is advanced at the same time when the upper surface of the thick paper (1A) comes into contact with it, and is fed to the pull-in roller (23). Hereafter, the same operation as described above is performed. Since the ion-containing air is blown out obliquely upward toward the tip of the plastic card (1B), the plastic card (1B) is floated by the ion-containing air and the separation effect is enhanced.

[0053]

As described above, according to the method of the present invention, the whole laminated sheet to be measured is moved in the laminating direction and supplied to the sheet-to-be-measured object taking-out portion, and at the sheet-to-be-measured object taking-out portion. In the method for supplying a measured sheet-like material in which the measured sheet-like objects are taken out one by one and supplied to the next step one by one, the uppermost measured sheet-like material is sucked from above. Since the uppermost sheet-like object to be measured is separated from the second sheet-like object to be measured, and the sheet-like object-to-be-measured conveying means is brought into contact with the upper surface of the sucked uppermost sheet-like object to be measured, it is sent out. A gap is formed between the second sheet to be measured and even if the uppermost sheet to be measured is pulled out, the space between the sheet to be measured does not become a depressurized state, and the uppermost sheet to be measured is not formed. If only the objects are taken out and there is a mistake in taking out Cormorants it is not. Further, upon taking out, the uppermost sheet-like object to be measured does not rub against the second sheet-like object to be measured, and static electricity is not generated. Further, since there is no stacking guide as in the conventional example, there is no need to adjust the gap between the sheet feeding belt and the stacking guide, and the printed surface of the measured sheet is scratched by the stacking guide. There is also no accident such as the occurrence of defects due to removal. Therefore, according to the method of the present invention, not only can the sheet-like objects to be measured be separated and taken out one by one, but also when the sheet-like objects to be measured are taken out, It has an advantage that almost no load is applied and the printed surface of the measured sheet-like material is not scratched.

A second aspect is a further improvement of the method according to the first aspect, in which air is blown toward the laminated sheet to be measured toward the laminating surface to supply air between the sheet to be measured. Air is forced to flow between the sheet-like objects to be measured, so that the sheet-like objects to be measured can be more easily and reliably separated.
