Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a sheet-like object number counting device for counting the number of sheets, each of which is a stack of a plurality of sheet-like objects, one by one via a rotating body, and a method for counting the number of separated sheets. Regarding technology.

[0002]

2. Description of the Related Art FIG. 4 shows a sheet counting head unit B in a conventional sheet counting device. The sheet counting head section B is a section for separating and counting sheet-like objects.
The sheet counting head unit B includes a suction blade D having an air suction hole C and a wiper push rod F connected to the wiper pin E.
Is configured to make a rotational movement G around the suction blade D via a wiper push rod F. Incidentally, G shown in FIGS. 4, 5, and 6 is a wiper pin E.
The operating trajectory of is shown. FIG. 5 is a perspective view in which the sheet-like material counting head portion B is arranged below the sheet corner portion I in the sheet bundle H in which a plurality of sheet-like objects are stacked, and J is a separation. Shows one sheet-like object.

6A to 6F show a mechanism and an operation of separating the sheet-like objects (for example, papers) forming the sheet bundle H one by one by the suction blade D and the wiper pin E.
Shown in. First, in FIG. 6A, the suction blade D of the sheet-like material counting head portion B, which is a portion for separating and counting sheet-like materials, is arranged so as to be located below the sheet corner portion I of the sheet bundle H. . Then, by sucking air through the air suction holes C provided in the suction blade D, one sheet-like object J that constitutes the sheet bundle H is adsorbed to the suction blade D.

Next, as shown in FIG. 6 (b), the suction blade D is swung so as to incline downward while attracting one corner portion I of one sheet-like object J. As a result, the attracted sheet-like material Ja is turned over, and a gap K is formed between the sheet-like material Jb to be sucked next.

Next, as shown in FIG. 6 (c), in the gap K formed between the sheet bundle H and the sheet bundle H, which is attracted by the sheet bundle H and the suction blade D and turned up,
The wiper pin E rotating around the suction blade D enters. The wiper pin E enters the gap K and moves upward from the lower side inclined on the upper surface of the suction blade D and wraps around the upper side of the suction blade D, and the lower surface of the wiper pin E extends downward from above. It is configured so as to push down Ja and further rotate in the rotation direction L so as to wrap around below the suction blade D.

Next, as shown in FIG. 6 (d), the wiper pin E that has entered the gap K is moved around the suction blade D in a predetermined rotation direction L by a motion and force, so that the suction blade D moves. The sheet-like object Ja that has been turned over by suction is pushed downward along the suction blade D so as to wrap around. Then, as shown in FIG. 6E, the sheet-like object Ja moves to the lower side of the suction blade D and can be separated and separated from the sheet bundle H.

At the same time, as shown in FIG. 6 (f), the suction blade D is returned in the horizontal direction, and the next sheet-like material Jb.
Aspirate. By repeating the above operation, the sheet-like material Jb is moved to the lower side of the suction blade D and separated.

In the conventional sheet-like material number counting machine, when the sheet-like material J is picked up, when the sheet-like material J is adsorbed, the suction hole C is blocked and further air cannot be sucked.
The air in the suction blade D has a low pressure. At this time, the fact that the air inside the suction blade D is in a low pressure state is detected by an air pressure sensor (not shown), and it is determined whether or not the sheet-like material J is adsorbed. When it is determined that the sheet-like material J is adsorbed, the wiper pin E rotates the operation track G in a predetermined rotation method L to advance the counting piece,
The number of sheets J is counted.

[0009]

As described above, the conventional sheet number counter sucks the sheet-like objects J one by one by the suction blade D. The suction blade D
The sheet-like material J adsorbed on the sheet-shaped material J is pushed down by the wiper pin E so as to wrap around the lower side of the suction blade D, and is repelled, whereby the sheet-shaped material J is separated below the suction blade D and counting is performed. Therefore, as shown in FIG. 6, even if the wiper pin E operates according to the operating trajectory G of the set wiper pin E while taking the normal position, the sheet-like object J sucked by the suction blade D is as designed. When the wiper pin E does not push down or does not contact the predetermined surface of the sheet-like object J, or when the wiper pin E pushes down the sheet-like object J and flips it down, a uniform force is applied to the surfaces of the wiper pin E and the sheet-like object J. If the impact force when the wiper pin E comes into contact with the sheet-shaped material J is not biased and is biased to a part of the surface of the sheet-shaped material J, an accident that the sheet-shaped material J is broken occurs. In such an accident, the wiper pin E and the wiper push rod F, which is a shaft that supports and rotates the wiper pin E, are consumed, so that the surface of the sheet-like object J attracted to the suction blade D and the wiper pin E. This is a phenomenon that occurs when it is no longer possible to maintain a uniform contact with the surface.

Further, since the operation speed of the suction blade D and the wiper pin E is increased by increasing the counting speed,
When the wiper pin E wraps around the sheet-like material J and pushes it downward and flips, the impact force becomes large, and the phenomenon of tearing of the sheet-like material J occurs.

An object of the present invention is to eliminate the occurrence of the above-mentioned phenomenon of breakage of the sheet-like material in the sheet counting head portion of the conventional sheet-like material number counting machine.

[0012]

In order to solve the above technical problems, the present invention has developed the following means.

According to a first invention to be granted a patent, in a sheet counting head portion of a sheet number counting machine, a rotating body having a suction hole is arranged near a free end of a sheet bundle fixed at a predetermined position. By the suction hole of the rotator, the vicinity of the free end of the sheet-like object is adsorbed on one side of the rotator, and the rotator rotates in the fixed side direction while adsorbing and holding the sheet-like object. The number of sheet-like objects, characterized in that the sheet-like objects are transferred to the other side of the rotating body and are separated by separating the suction part of the sheet-like objects, and the number of the separated sheet-like objects is counted. It is a counter.

The first invention is a basic invention of the developed sheet-like material number counter. The sheet-like object counting head unit is configured such that a rotating body having a suction hole is provided near the free end of a sheet bundle fixed at a predetermined position, and the rotating body is made rotatable and capable of sucking. The characteristic feature is that the sheet-like material necessary for separating the sheet-like material can be adsorbed, transferred, and separated by only the action of the rotating body. Since the number of constituent members is small and the size is small, and there is no physical impact on the sheet-like material, there is no accidental breakage of the sheet-like material even if the speed is increased.

According to a second invention to obtain a patent, in a sheet counting head portion of a sheet number counting machine, a rotating body having a suction hole is made into a bundle by stacking a plurality of sheet types. Arranged so as to contact one surface in the vicinity of one corner of the sheet bundle that becomes a free end when the sheet bundle is fixed at a predetermined position, and to apply suction force to the suction hole of the rotating body, The rotating body is configured to be rotatable in the fixed side direction, the rotating body is rotated in the fixed side direction, and the sheet-like object comes into contact with the suction hole on one side of the rotating body. At that time or immediately before that, suction force is applied to the suction hole of the rotating body so that the contacted sheet-like material can be adsorbed, and the one sheet-like object is fixed while adsorbing and holding it in the suction hole. When it is rotated in the lateral direction, it is in the form of a single sheet The suction part of the rotating body rotates on one side of the rotating body so as to draw an arcuate locus, thereby slackening the sucked sheet-like object and moving one corner of the free end from the one side of the rotating body to the other side. When the sucked sheet-shaped object is transferred to the other side of the rotating body and is not returned, the suction force is stopped and the sucked portion is separated to transfer the sheet-shaped object. The number of sheets of sheet-like material separated from a bundle of sheets on one side and transferred to the other side is maintained by separating the sheet bundle on one side from the rotation speed and / or suction force of the rotating body. Counting is performed based on the change, and when the rotating body is further rotated and the suction hole comes into contact with the next sheet-like object or immediately before that, suction force is applied to the suction hole to Adsorbs the sheet-like material, transfers it to the other side of the rotating body, and stops the suction force. By separating the suction part and maintaining the sheet-like object on the other side of the rotating body and separating it, and repeating the counting of the number of sheets, the fixed sheet bundle is separated one by one and the number of sheets is counted. It is a featured sheet-like object counter.

According to the second aspect of the present invention, the rotating body having the suction holes is configured to rotate in the fixed side direction, and the sheet-like material imparts suction force to the suction holes provided in the rotating body. When it comes into contact with one side or immediately before that, the sheet-like material is adsorbed, and while the sheet-like material is adsorbed and held in the suction hole, the adsorbed sheet-shaped material is rotated toward the fixed side. When the sheet is transferred to the other side of the rotating body and does not return to the other side, the suction force applied is stopped, the suction unit is separated, and the transferred sheet-like object is maintained on the other side of the rotating body. , By combining both, by applying or stopping the suction force to the suction hole while rotating the rotating body, a sheet-like material is stacked from a plurality of sheet-like materials to form a sheet-like material. Adsorb one by one, transfer from one side of the rotating body to the other side, Separating so as to maintain the door-like material to the other side, the number of sheet of the rotating body rotational speed and /
Alternatively, it is a sheet-like material number counter adapted to count based on a change in suction force. According to the present invention, the sheet-like material can be counted one by one from a sheet bundle obtained by stacking a plurality of sheet-like materials to form a bundle only by the action of the rotating body having a small number of parts. This is a more specific clarification of the structure of the item counter.

A third aspect of the present invention, which intends to receive a patent, is to form a sheet counting head portion of a sheet-like object number counting machine, in which all or part of the outer peripheral surface is formed in an arc shape. A suction hole is opened on the arc-shaped outer peripheral surface, and a part of the arc-shaped locus of the suction hole is fixed at a predetermined position by rotating while applying suction force to the suction hole. It is the sheet number counting machine according to the first invention or the second invention, which is arranged so as to contact one surface of the sheet bundle.

The third aspect of the invention is a subordinate claim in which the form and the position of the rotating body forming the sheet counting head portion of the sheet number counting machine are specified. The entire outer peripheral surface of the rotating body may be formed in an arc shape, or a part of the outer peripheral surface may be formed in an arc shape. For example, the cross-sectional shape may be circular, oval, or elliptical, and the cross-sectional shape may be ginkgo-shaped or triangular with a bottom surface being arcuate. Incidentally, the shape of the rotating body, if all or part of the outer peripheral surface is formed in an arc shape,
Needless to say, the shape is not limited to the above-described exemplary shape.

According to a fourth aspect of the invention, which is going to receive a patent, when a sheet-shaped material comes into contact with the suction hole on one side of the rotating body, suction force is started to adsorb the sheet-shaped material, and the suction force is used as a reference point. While the sheet-like object is sucked and held in the suction hole, the sheet-like object is rotated in the direction of the fixed side, and while the sucked sheet-like object is sagging, one corner of the free end is transferred from one side of the rotating body to the other side. None, at the time when the suction portion of the sucked one sheet-shaped object becomes a rotation angle of 80 degrees to 120 degrees from the reference point,
The sheet-like material according to the first or second invention, characterized in that the suction force is stopped and the suction portion is separated, and the transferred sheet-like material is maintained and separated on the other side of the rotating body. It is a number counter.

The fourth aspect of the invention specifically shows the timing of applying the suction force applied to the suction hole provided in the rotating body and the timing of stopping the applied suction force. The start timing of applying the suction force is when the suction force comes into contact with the sheet-like object on one side of the rotating body or immediately before that, and when it becomes a rotation angle of 80 degrees to 120 degrees with the reference point as the reference point. It is desirable to stop the suction force at. Specifically, the timing at which the suction force is stopped is determined depending on the rotation speed of the rotating body, the thickness and physical properties of the sheet-like material, and the like. As a result, while the sheet-like object is sucked and held in the suction hole, the sheet-shaped object is rotated in the direction of the fixed side, and when one sheet-like object that has been sucked is transferred to the other side of the rotating body and cannot be returned, It is possible to stop the sucking force that had been applied, and keep the sheet-like material transferred away from the suction portion on the other side of the rotating body.

According to a fifth aspect of the present invention, a sheet counting head portion of a sheet-like object counter is a rotating body having a suction hole to which a suction force can be applied, and the sheet is fixed to the rotating body. It is arranged so as to be near the free end of the bundle, and when the rotating body is rotated in the fixed side direction and the sheet-like object comes into contact with the suction hole on one side of the rotating body, A suction force is applied to the suction hole to adsorb only one sheet-like material that has come into contact with the suction hole, and the rotating body is rotated in the direction of the fixed side as it is while adsorbing and holding the one sheet-like material. When transferred from one side of the rotating body to the other side and the adsorbed sheet-like material is not returned to the one side,
Stopping the suction force and releasing it, keeping the transferred sheet-like object on the other side of the rotating body so that it can be separated, and counting the number of separated sheets. Is the way.

The fifth aspect of the present invention is a basic invention of a sorting counting method for sheets. By rotating the rotating body, which is a component of the sheet-like object counting head unit, in the direction of the fixed side and sucking it, one sheet-like object is adsorbed from a plurality of sheet-like objects that are bundled and fixed to one side. To the other side, and when the sheet-like material does not return to the one side, the suction force is stopped and released, and the transferred sheet-like material is maintained on the other side of the rotating body and separated. This is a method for counting the number of separated sheet-like objects by counting the number of separated sheets. As described above, the present invention performs the work of separating the sheet-like material only by rotating the rotary member and turning on / off the suction force, and a physical impact such as hitting another member to the sheet-like object during the separation work. Therefore, even if the sorting work is sped up, there is no accident that the sheet material is accidentally torn.

According to a sixth aspect of the present invention, which is intended to receive a patent, a sheet counting head portion of a sheet number counting machine is a rotating body having a suction hole capable of imparting a suction force, and the sheet bundle is fixed. Is arranged near the free end of the rotating body, the rotating body is rotated in the fixed side direction, and when the sheet-like object comes into contact with the suction hole on one side of the rotating body, immediately before the rotation. A suction force is applied to the suction hole of the body to adsorb only one sheet-shaped object that has come into contact with it, and while further adsorbing and holding this sheet-shaped object, the sheet-shaped object adsorbing portion has an arc shape. While rotating along a locus, the corners that are the free ends of the adsorbed sheet-like material are transferred from one side to the other while sagging the adsorbed sheet-like material. When it is transferred to the side and it does not return,
The suction force is stopped, and the sheet-like material transferred away from the suction unit is maintained and separated on the other side of the rotating body, and the number of sheet-like objects separated from the sheet bundle on one side is determined by the number of rotations of the rotating body and / or Alternatively, counting is performed based on a change in the suction force, and when the rotating body further rotates, the suction hole comes into contact with and adsorbs one sheet of the next unsorted sheet bundle, transfers this to the other side of the rotating body, and sucks the suction force. Stop and release the sheet-like material to maintain the sheet-like material on the other side of the rotating body and separate the sheets, and repeat counting the number of separated sheets to separate the sheet-like objects in the fixed sheet bundle one by one. The method for counting the number of sheets is characterized in that the number of sheets is counted.

FIG. 9 is a side view illustrating sequentially the movement of the sheet bundle by activating the sheet bundle.

FIG. 1 shows a sheet counting head portion A of a sheet-like object number counter according to the present invention. The sheet counting head unit A can suck air from the rotating body 1 including the cylindrical suction roller 3 having the suction hole 2 and the suction hole 2 provided in the suction roller 3. The suction mechanism 4 is configured as described above. The rotating body 1 is
A cylindrical suction roller 3 having a suction hole 2, a shaft 5 for axially mounting the suction roller 3, and a pulley 6 for axially rotating the suction roller 3 on the shaft 5. A driving belt 7 is hung on the pulley 6 to rotate the pulley 6. The shaft 5 penetrates the suction roller 3, the pulley 6, and the sleeve 8. Moreover, by connecting the belt 7 to a rotational power device such as a motor (not shown), the rotational power can be transmitted to the pulley 6 and the suction roller 3 can be rotated.

The suction mechanism 4 connects the suction device (not shown), the suction pipe 4a connected to the suction device, and the suction roller 4 having the suction hole 4 to the suction roller 4a. And a sleeve 8 capable of applying a suction force to the working hole 2. Therefore, the suction mechanism 4
Is operated, air can be sucked from the suction hole 2 of the suction roller 3 through the inside of the suction pipe 4a and the sleeve 8 which are connected. That is, the rotating body 1 is configured to be able to apply a suction force to the suction hole 2 via the suction mechanism 4 and to rotate the rotating body 1 freely, in particular, to rotate in the fixing side direction X of the sheet-like material. Configured to obtain.

Further, as shown in FIGS. 2 and 3, the rotating body 1 has a free end when the sheet bundle 9 formed by stacking a plurality of sheet-like materials 9a is fixed at a predetermined position 9c. The sheet bundle 9 is arranged so as to come into contact with one surface of the front surface or the back surface in the vicinity of one corner portion 9b of the sheet bundle 9.

Then, the rotary body 1 is rotated in the fixed side direction X while applying or stopping the suction force to the suction hole 2 of the suction roller 3 which is the rotary body 1. 3A to 3E show the mechanism and operation of separating and counting the sheet-like material by the rotation of the suction roller 3 at that time.

First, as shown in FIG. 3 (a), the rotating body 1 which is a part for counting and counting sheets is a sheet bundle 9 formed by stacking a plurality of sheet-like objects 9a and a free end thereof. Since it is located below the corner portion 9b, the rotating body 1 is rotated in the fixed side direction X, and the surface of the suction roller 3 having the suction hole 2 contacts one surface of the sheet-like material 9a. The suction force is applied to the suction hole 2 of the rotating body 1 at a timing immediately before or at a timing immediately before that, and only one sheet-like material in contact is attracted to the suction roller 3 at one side thereof.

Next, as shown in FIG. 3 (b), when the one sheet 9a is sucked and held in the suction hole 2 of the suction roller 3 and rotated in the fixed side direction X, the suction is performed. The suction portion of the sheet-shaped material 9a rotates along with the rotation of the rotating body 1 on one side of the suction roller 3 while drawing an arcuate locus. Then, the adsorbed sheet-shaped material 9a is slackened and the one corner portion 9b, which is its free end, is transferred from one side of the rotating body to the other side.

Next, as shown in FIG. 3C, when the rotation of the rotary body 1 is advanced and the arcuate locus of the suction hole 2 exceeds its apex (the position closest to the fixed end of the sheet-shaped material 9a). , The corner portion 9 which is the free end of the transferred sheet-like material 9a
b moves from one side of the suction roller 3, which is the rotating body 1, to the other side.

Further, as shown in FIG. 3 (d), when the rotation is further advanced while adsorbing and holding it, the sheet-like material is transferred from one side to the other side, whereby the adsorbed one sheet-like material. 9a is transferred to the other side of the rotating body 1 and is not returned. At that time, the suction force applied to the suction hole 2 is stopped and the suction portion is separated so that the transferred sheet-shaped material 9a is maintained on the other side of the rotating body 1. In the embodiment, the sheet-shaped material 9a is provided in the suction hole 2 and the rotator 1
At the point of contact on one side, the suction force starts and it sucks,
With this as a reference point (0 degree), the sheet-shaped material 9a is rotated in the fixed side direction X while being suction-held in the suction hole 2, and the suction portion of the one sheet-shaped material 9a that has been sucked is the reference point. When the suction angle is stopped and the suction portion is released at the time when the rotation angle reaches from 80 degrees to 120 degrees, as shown in FIG. 1
It will be transferred to the other side and will not return. Specifically, it is desirable to determine the timing at which the suction force is stopped, depending on the rotation speed of the rotating body 1 and the thickness and physical properties of the sheet-shaped material 9a.

As shown in FIG. 3E, when the sheet-like material 9a on one side is transferred to the other side and does not return,
The number of the separated sheet-shaped products 9a is counted based on the change in the number of rotations of the suction roller 3 of the rotating body 1 and / or the suction force. If the counting of the paper is displayed only by the number of rotations of the rotating body 1, the sheet-like material 9a is rotated even if it is rotating.
Since it counts in accordance with the rotation even though it is not properly separated, it was decided to monitor the pressure change of the adsorption part using a pressure sensor and to count the number of sheets by the combination of both information.

When the suction roller 3 which is the rotary body 1 is further rotated, when the suction hole 2 comes into contact with the next undivided sheet-like material 9a, as in the case shown in FIG. 3A, or It is adsorbed immediately before and is transferred from one side of the rotating body 1 to the other side, the suction force is stopped and the sheet-shaped material 9a is separated to maintain the sheet-shaped material 9a on the other side of the rotating body 1. Handling,
By repeating the counting of this number,
This is a method of counting the number of sheet-like objects 9a in which the sheet-like objects 9a of the fixed sheet bundle 9 are sorted one by one and the number is counted.

Next, a method of separating the sheet bundle 9 and counting the number of sheets will be specifically described. For example, when separating the sheet-like material 9a, if the suction holes 2 are closed by suction of the sheet-like material 9a, Air cannot be sucked any more, and the air pressure in the suction roller 3 that is the rotating body 1 becomes low. The low-pressure state is sensed by a separately provided air pressure sensor (not shown), and it is determined that the sheet-like object 9a is present when the low-pressure state is present and that the sheet-like object 9a is absent when the low-pressure state is not present. When it is determined that the sheet-shaped material 9a is present, the suction roller 3 rotates once to advance the counting by one frame, and the number of sheets is counted.

As described above, the rotating body 1 which constitutes the sheet counting head portion A sucks the sheet-like material 9a and transfers it from one side of the rotating body 1 to the other side, and stops the suction force to stop the sheet-like material 9a.
The number of sheets can be counted by separating the sheet-shaped material 9a while keeping the sheet-shaped material 9a on the other side of the rotating body 1. In this manner, the separation of the sheet-shaped material 9a and the suction, transfer, and separation of the sheet-shaped material 9a necessary for counting the number of sheets can be performed only by the action of the rotating body 1. Therefore, the number of constituent members can be reduced, and the sheet can be downsized. Since there is no physical impact on the sheet 9a, even if the speed is increased, the sheet 9
There is no accident of breaking a.

The rotating body 1 may have a cylindrical shape and a suction hole 2 on its side surface, as in the illustrated embodiment. The whole may be formed in an arc shape, or a part of the outer peripheral surface may be formed in an arc shape. For example, the cross-sectional shape may be circular, oval, or elliptical, and the cross-sectional shape may be ginkgo-shaped or triangular with a bottom surface being arcuate. That is, it goes without saying that the shape of the rotary body 1 is not limited to the above-described exemplary shape as long as the outer peripheral surface of the rotary body 1 is entirely or partially formed in an arc shape.

Furthermore, the sheet material 9a according to the present invention is
Not only paper, but also various materials such as films, fiber materials, synthetic resin materials, and metal foils are targeted. In this way, in order to sort and count the sheet-shaped objects 9a having different physical properties, the sheet-shaped objects 9a in the rotating body 1 constituting the sheet counting head unit A are
In any case, it is possible to smoothly handle the suction force by changing the strength of the suction force, the timing of starting and stopping the suction, and adjusting the suction time according to the physical properties of.

Furthermore, if the suction roller 3 of the rotating body 1 is manufactured by using a material having abrasion resistance such as metal, the abrasion can be reduced even if it is used for a long period of time, and It is possible to separate the sheet-shaped material 9a stably and to count the material. The suction roller 3, which is the rotating body 1, may be made of a single material, or may be made of a combination of different materials, such as a metal material surface coated with a rubber material at appropriate positions. May be.

[0041]

Accordingly, the sheet-like object number counting device according to the present invention has the mechanism for separating the sheet-like objects by the suction and the rotational operation of the rotating body as described above, and thus the conventional wiper pin and the suction blade. Since the sheet-like material is not subjected to a strong impact force even when the rotation speed is increased, like the separating mechanism having the above, it is possible to prevent the sheet-like material from being inadvertently broken.

Further, according to the present invention, the mechanism for separating the sheet-like object by the suction and rotation operation of the rotating body alone is not only downsized, but also has a simple structure. As a result, the number of adjustment points is reduced.

Further, since the method for counting the separation of the sheet-like material according to the present invention is a method of separating by the suction, transfer and peeling action of the rotating body alone, it is sucked even if the rotating speed of the rotating body is increased. This is a novel method for counting the number of sheets to be sorted, in which the impact force on the sheet when sorting the sheets is reduced, and inadvertent tearing of the sheets can be prevented.

Furthermore, the method for counting the separation of sheet-like objects according to the present invention is a system in which the sheet-like objects can be separated only by the suction and rotating action of the rotating body, and a physical impact force on the sheet-like objects is hardly applied. Since the sheets can be separated in this way, it is possible to count even sheet-like objects having low tensile strength and impact strength, and the range of sheet-like objects that can be separated is widened. Moreover, since the suction force and the start and stop timings of suction can be easily adjusted, even if it is a soft and thin sheet, which was thought to be difficult in the past, the sheet does not break. I was able to handle it.
