Problems have been pointed out.

In particular, when selectively feeding many types of sheets with different thicknesses, this adjustment and change operation must be performed every time the thickness is changed, and an improvement has been required.

This invention has been made in view of the above-mentioned problems, and an object of the invention is to arbitrarily adjust the amount of gear between the feed means and the gate member in order to prevent double feeding, and to

The type numbers are positioned so that they are the same in the longitudinal direction and the same distance from the lower edge in the width direction.In other words, these two types of treasure tickets W,...
The three types of numbers are set so as to be positioned at the same position when the W is placed upright and lined up.

In addition, in the following explanation, when there is no need to take into account the difference in thickness, the treasury tickets will be collectively indicated with the symbol W.
Also, if differences in thickness must be taken into account,
Let them be denoted by the symbols W, , W, respectively.

Here, the above-mentioned number recognition inspection device 22 reads and recognizes the group number GR1 lottery number SQ printed on the treasure ticket W and the B font number BF to check the continuity of the numbers, although the details will be described later. The apparatus is configured to inspect character quality such as irregularities, stains, and missing characters in numbers.

The lottery tickets W are placed on the feed stocker mechanism 14 as described above in a state where they are erected on their sides, in other words, in a state where their respective longitudinal directions are oriented in the horizontal direction.
A large number of tickets of each type are stored at one time, for example, in groups of the same school or 500 tickets.

As shown in FIG. 2, this feed stocker mechanism 14 includes a stocker body 26 that is defined by including the upper surface of the housing 12, and a stacking direction of treasure tickets W accumulated on this stocker body 26. A pressing member 28 is attached to be movable along the same direction, and the pressing member 28 is biased toward a feed drum 30 of a feed mechanism 16 to be described later. It is composed of a biasing mechanism 32 that biases the body.

That is, this biasing mechanism 32 includes a reversible AC torque motor 32a and a first motor rotatably attached to the take-out position side and the opposite side of the stocker body 26, respectively.

is biased toward the feed drum 30, and the treasure tickets W accumulated on the stocker body 26 are pressed against the feed drum 30 with a predetermined force.

Next, with reference to FIG. 2, the configuration of the feed mechanism 16 described above will be explained in detail.

This feed mechanism 16 includes a feed drum 30 rotatably supported around a vertical axis, and a feed drum 30 that is rotatably supported around a vertical axis.
a drive mechanism 34 that rotationally drives the feed drum 30;
A plurality of idle rollers 36a, 36 in rolling contact with the outer peripheral surface of
b. Note that the first idle roller 36a is connected to a feed drum 3o by a reverse roller 50, which will be described later.
The second idle roller 36b is positioned on the outer circumferential surface of the feed drum 30, and the second idle roller 36b is positioned at a separation position where the lottery ticket W is separated from the feed drum 3o. They are attached so that they come into elastic contact.

Here, the outer circumference of the feed drum 30 is such that the tip of one of the plurality of lottery tickets W pressed by the pressing member 28 in the feed stocker mechanism 14 mentioned above, which is closest to the feed mechanism 16, comes into contact with the feed drum 30. It is arranged in a position with a surface. Further, as shown in FIG. 2, the drive mechanism 34 includes a drive motor 34a and a drive motor 34a.
The feed drum 30 includes a pair of belts 34b and 34c that sequentially transmit driving force to the feed drum 30.

The drive mechanism 34 is set to rotate the feed roller 30 at, for example, 75 degrees r, p, and s in the counterclockwise direction in the figure. Further, the position at which the tip of the lottery ticket W comes into contact with the outer circumferential surface of the feed drum 30 is defined as the take-out position of the lottery ticket W.

As shown in FIG. 4A, the feed drum 30 includes a metal drum body 30a made of a hollow cylindrical body, and a metal drum body 30a that is affixed to the outer peripheral surface of the drum body 30a over the entire circumference. Friction sheet 30 made of urethane rubber
In this embodiment, the circumferential length is set to 612.3 mm. As a result, the rotation time per 1 mm on the outer peripheral surface of the feed drum 30 (i.e., the reciprocal of the peripheral speed) is 0.8163 m5/mm.
It will be stipulated by

Here, as shown in FIG. 4B, on the outer circumferential surface of the feed drum 30, a suction hole group 38 consisting of three through hole groups is formed through the drum body 30a and the friction sheet 30b.
a, 38 b, 38 c are equally spaced, i.e. 120
It is formed at intervals.

As a result, suction hole groups 38a are adjacent to each other.

The distance between 38b and 38c is 204.1 am, and the length in the feeding direction is 15011 Im.
Three sheets can be attracted to the outer periphery of the feed drum 3o with sufficient distance from each other.

On the other hand, the internal space of the feed drum 30 is connected to a vacuum pump 42 as a suction source via a duct 40, as shown in FIG.

On the other hand, as shown in FIG. 4B, a wind shielding member 44 is fixedly disposed on the outer circumference of the feed drum 30 over a range from the separation position to the take-out position along the rotational direction. The wind shielding member 44 is set to come into sliding contact with the outer peripheral surface of the feed drum 3o. As a result, the suction hole group 38a formed at three locations as described above.
.

Among 38b and 38c, only the one located at the separation position along the rotational direction from the take-out position is in a state where it communicates with the atmosphere, and a negative pressure serving as a suction driving force is generated there.

By providing the wind shielding member 44 in this manner, negative pressure is generated only in the suction hole groups 38 a, 38 b, and 38 c that attempt to suction the treasure ticket W onto the outer peripheral surface of the feed drum 30. The magnitude of this negative pressure is set to be thicker than when all three suction hole groups 38a, 38b, and 38c are open, and a reliable suction operation is achieved. .

Further, by configuring the feed mechanism 16 in this way, the suction hole groups 38a and 38b are located in the range from the take-out position to the separation position along the rotational direction when the vacuum pump 42 is driven.

38c, and the treasure ticket W that contacts the suction hole groups 38a, 38b, and 38c on which the negative pressure acts is attracted to the outer peripheral surface of the feed drum 30 by this negative pressure and is driven. Feed drum 30 as motor 38 is driven
This rotation causes the lottery ticket W to be taken out from the feed stocker mechanism 14.

As described above, since the friction sheet 30b is attached to the outer circumferential surface of the drum body 30a of the feed drum 30, the treasure sucked to the outer circumferential surface of the feed drum 30 by negative pressure is removed. Even if the ticket W is in a state where there is no negative pressure, the above-mentioned idle rollers 36a, 3
6b, conveying force is applied by being held between them. In other words, as described above, the treasure ticket W transported from the take-out position to the separation position is sequentially moved by the feed drum 30 by the pair of idle rollers 36a and 36b while being subjected to negative pressure as a suction force. Since it is held between the outer circumferential surface and the outer circumferential surface, a state of reliable conveyance is achieved.

On the other hand, in this embodiment, as described above, since the number recognition inspection device 22 is configured to inspect the continuity of the numbers of the treasure ticket W being conveyed, the (The feeding of two sheets of the same ticket W (hereinafter referred to as double feed) must be strictly prevented. For this reason, in this embodiment, the feed stocker mechanism 14 is A double feed prevention mechanism 46 is disposed at a position adjacent to (that is, counterclockwise) to prevent double feed.

As shown in FIG. 5, this double feed prevention mechanism 46 is supported so as to be movable along the radial direction, and has a variable distance (gap) between it and the feed drum 30, and is driven by a drive motor 48. The reverse roller 50, which functions as a gate member and is driven to rotate along the same direction as the feed drum 30 (that is, along the direction opposite to the conveyance direction), and the gap It is comprised of a gap amount defining mechanism 52 which defines the radial position of the reverse roller 50 so that the note W passes through, which is a feature of the present invention.

Here, this gap amount regulating mechanism 52 is connected to the reverse roller 50, and is based on the step motor 54 that moves and drives the reverse roller 50 to an arbitrary position along the radial direction, and the information input through the above-mentioned operation panel Pr. , lottery ticket W
, , a thickness setting mechanism 56 that selectively sets the thicknesses T, , T, of the types of W2, and a motor control mechanism 58 that drives and controls the step motor 54 according to the thickness setting mechanism 56.
It is composed of.

That is, in this embodiment, the thickness setting mechanism 56 sets two different thicknesses, T+ and T-, as described above.
is selectively set. For example, when a thin thickness T (=80 μm) is set, a corresponding narrow first reference gap amount R1 (=TI+TI/2=
120 μm), and the first control amount is output to the motor control mechanism 58, and when the thick thickness Ta (=250 μm) is set,
A correspondingly wide second standard gap amount R2 (=72
+72/2=375 am), the second control amount is output to the motor control fi1 mechanism 58.

The above-mentioned motor control mechanism 58 is configured to drive and control the step motor 54 based on the control amount outputted from the thickness setting mechanism 56 so as to achieve the corresponding reference gap amount. has been done. As is clear from FIG. 5, a reverse roller home position sensor 60 is connected to the motor control mechanism 58 in order to accurately define these reference gap amounts.

This reverse roller home position sensor 60 is biased radially outward by 500 μm from the outer peripheral surface of the feed drum 30 when it is stopped at a predetermined rotational position (that is, a drum home position sensor 62 described later is turned on). Fixed in position. As a result, the motor control mechanism 58 sets the position where the reverse roller home position sensor 6o is turned on as zero, and its movement reference is accurately defined. The position of the reverse roller 50 relative to the feed drum 30 is accurately defined by controlling the step motor 54 to move radially inward from the reverse roller home position sensor 60.

In other words, for example, when feeding a thin treasure ticket W1, the distance from the outer peripheral surface of the feed drum 30 is the first reference gap amount R, (120 μm), and when feeding a thick treasure ticket W2, In the case of feeding, the reverse rollers 50 will be precisely positioned at positions radially outwardly spaced from each other by a second reference gap f![2 (375 μm).

The drum home position sensor 62 described above is positioned at a position where it is turned on immediately before the first suction hole group 38a comes off the wind shielding member 44 and is brought to the take-out position, as shown in FIG. 4B. .

As described in detail above, since the gap amount regulating mechanism 52 of this embodiment is configured, the thickness setting mechanism 56 selectively sets the thickness of the lottery tickets W, W2, and adjusts the thickness to this setting. Accordingly, the motor control mechanism 58 drives and controls the step motor 54 so as to accurately define the first or second reference gap amount R,,R, described above, so that the lottery ticket has two thicknesses. However, the first or second reference gap amount R, , R, which is optimal for each sheet to pass through the gap, is automatically and accurately set. That will happen.

Here, the outer circumferential surface of the feed drum 30 does not constitute a perfect circle, and
The center axis of 0 is also slightly eccentric from the designed center position.

As a result, as described above, a predetermined gap amount R is established corresponding to the selected thickness T3.Ta of the treasure ticket w, , Wl.
, , R, respectively. As the feed drum 30 rotates, the outer circumferential surface of the feed drum 30 repeatedly approaches and separates from the outer circumferential surface of the reverse roller 50, and the actual gap amount between the feed roller 30 and the reverse roller 50 changes periodically. It turns out.

Then, the change in this gap amount is, for example, a thin treasure (
If the same ticket W changes in the positive direction by T1/2 of 40 μm or more, there is a possibility of double feeding, and if it changes in the negative direction, it will not be fed.

Therefore, in this embodiment, the feed drum 30
Based on the eccentricity of An eccentricity detection mechanism 64 for detecting the eccentricity of the feed drum 30 is connected to the motor control mechanism 513 in order to drive and control the step motor 54 via the motor control mechanism 58 described above so as to suppress the amount of eccentricity to T2/2 or less. There is.

This eccentricity detection mechanism 64 will be explained below with reference to FIG. 5.

This eccentricity detection mechanism 64 includes a swinging arm 66 that is swingably supported in the center, and this swinging arm 66
The first idle roller 36a described above is rotatably supported at one end of the roller.

Further, the swing arm 66 is always urged by a coil spring 68 so that the first idle roller 36a is pressed against the outer peripheral surface of the feed drum 30.

Further, a magnet 70 is fixed to the other end of the swing arm 66, and a sensor 72 including a Hall element is disposed opposite to the magnet 70.

This sensor 72 is configured to detect the separation distance from the opposing magnet 70, and the detection result is stored in the number recognition inspection device 22 together with a storage circuit 74, which will be described later, as the measured eccentricity. It is designed to be output.

That is, in this eccentricity detection mechanism 64, when the first idle roller 36a is in pressure contact with the outer circumferential surface of the feed drum 30, by rotating the feed drum 30 once without feeding the lottery ticket W, The amount of eccentricity of the feed drum 30 can be measured. In detail, as described above, from the position where the drum home position sensor 62 is turned on, the feed drum 3
When 0 is rotated once, if the detection distance of the sensor 72 at this ON position is set to 0, this detection result (i.e. eccentricity) will change periodically as shown by the solid line in FIG. 6, for example. There will be changes.

In this way, the amount of eccentricity of the feed drum 30 is detected based on the detection result from the sensor 72, and this amount of eccentricity is determined by the amount of eccentricity of the other suction hole group 38b.

The angular position where 38c faces the reverse roller 50 (
That is, when the angular position at which the drum home position sensor 62 is turned on is set to zero, there are angles of 120 degrees and 240 degrees from this point.
As shown in FIG. 6, it can be seen that the angle is +100 μm and −60 μm at the angular position (in degrees). Here, a positive eccentricity indicates a change radially outward from the zero point position, and a negative eccentricity indicates a change radially inward.

In a state where the amount of eccentricity changes in this way, for example, when feeding a thin treasure ticket W1, the reference gap amount R3
is set to 120ILm, and the amount of eccentricity at an angular position of 120 degrees is plus 100 μm, so the substantial gap is 1l20−1O0=20u. Therefore, it is sucked into the second suction hole group 38b and fed (
The lottery ticket W, which has a thickness of 80 μm, is 20 μm thick.
The feed cannot pass through the gap, resulting in a state where feed is not possible.

On the other hand, the eccentricity at the angular position of 240 degrees is -6
Since it is 0 μm, the effective gap is 120− (
-60)=180 μm. Therefore, two of the treasure tickets W1 that are sucked and fed into the third suction hole group 38c are taken out at the take-out position, and the total thickness is 8
Even if 0X2=160ALm, even though the reverse roller 50 is provided, it will pass through this 180 μm gap as it is, that is, it will be double fed.

Therefore, in this embodiment, both the measurement result of the amount of eccentricity detected by the sensor 72 and the measurement result by the drum rotation angle detection mechanism 76 that detects the rotation angle from the zero point position of the feed drum 30 are It is output to the storage circuit 74, where it is set to be stored as the amount of eccentricity for each rotation angle of the feed drum 30. Then, when the actual feeding operation of the treasure ticket W is started, as the feed drum 30 rotates, the amount of eccentricity corresponding to the rotation angle detected by the drum rotation angle detection mechanism 76 is detected by the motor from the memory circuit 74. The motor control mechanism 58 corrects the reference gap amount by this amount of eccentricity so that the gap 1 between the feed drum 30 and the reverse roller 5o is always equal to the constant gap R1. The reverse roller 50 is driven to move along the radial direction.

In this way, this embodiment includes the eccentricity detection mechanism 64 and finely adjusts the radial position of the reverse roller 50 based on the detection result, so that the reverse roller 50 of the feed drum 30 The radial position of the outer circumferential surface of the reverse roller 50 at the position opposite to the feed drum 30 and the radial position of the outer circumferential surface of the reverse roller 50 close to the feed drum 30 change as shown by solid lines and broken lines in FIG. 6, respectively. As a result, the gap amount between the feed drum 30 and the reverse roller 50 is kept constant at the predetermined reference gap IR or R2,
Double feeding of the lottery ticket W is reliably prevented.Here, the detection result from this sensor 72 is only available when the eccentricity measurement mode is set before executing the predetermined feeding operation. , is output to the memory circuit 74, and when the eccentricity for each rotation angle of the feed drum 30 is determined and the feed mode of the treasure ticket W is set, the value is output to the memory circuit 74. Instead, it is output only to the number recognition inspection device 22.

In other words, when the eccentricity measurement mode is set, the drum rotation angle detection mechanism 76 sets a write address in the storage circuit 74 to specify the rotation angle corresponding to the detected eccentricity as an address. In the state where the feed mode is set, it functions as a read address setting means when reading out the amount of eccentricity stored in the storage circuit 74.

In the state where the feed mode is set as described above, the number recognition inspection device 22 detects the presence or absence of double feed and checks the number of passed sheets based on the detection result from the sensor 72.

That is, as described above, the friction sheet 30b made of urethane rubber is adhered to the surface of the feed drum 30, and this friction sheet 30b gradually wears out as the feeding operation is performed. With this wear, the gap amount between the reverse roller 50 and the reverse roller 50 gradually increases, and even if this gap amount is kept constant at the reference gap amount R+ or R8 as described above, In some cases, the thickness becomes larger than twice the thickness of the lottery ticket W to be fed due to wear due to the outer circumferential surface of the feed drum 30, and in this case, double feeding occurs.

Therefore, in the number recognition inspection device 22, the sensor 7
Based on the detection result from 2, the amount by which this first idle roller 36a is pushed outward in the radial direction is constantly monitored as the amount indicating the thickness of the passing treasure ticket W. If the amount is determined to be twice the thickness of the currently fed treasure ticket, it is assumed that double feeding has occurred due to wear, and a predetermined alarm is issued and the detection result is displayed. , is configured to be printed and displayed on the printing device I. Based on the detection result, the operator performs an operation to replace the friction sheet 30b in the feed drum 3°.

On the other hand, this sensor 72 changes its output value in the direction of increasing from the reference value every time the fed treasure ticket W passes and the first idle roller 36a separates from the outer peripheral surface of the feed roller 30. In this way, each time the detection output from the sensor 72 increases from the reference value, the number recognition inspection device 22 sets the counter of the number of passed tickets to rlJ, assuming that one treasure ticket W has passed. It is set to update only.

That is, in this embodiment, this eccentricity detection mechanism 6
4 is the feed drum 3 in the eccentricity measurement mode.
It functions as a mechanism for measuring the amount of eccentricity at 0, and in the feed mode, it functions as a double feed detection mechanism and also functions as a mechanical counter.

Next, the lottery ticket W being fed by this feed mechanism 16 is peeled off from the top of the feed drum 30, and
The separation feed mechanism 80 for feeding to the transport mechanism 20 will be described with reference to FIGS. 7 and 9B.

As shown in FIG. 7, this separation feed mechanism 80 has three separation belts 82a, 82 that are longer than the outer circumference of the feed drum 30 and are wound around most of the outer circumference of the feed drum 30. b.

82c, and these separation belts 82a, 82b are set parallel to the central axis of the feed drum 30.

Separation rollers 84a, 84b, and 84c wound so that a part of rollers 82c are in contact with each other are coaxially fixed to a rotary support shaft 86 and rotatably supported, and a one-way clutch 88a is attached to this rotary support shaft 86.

feed rollers 90a attached via 88b, respectively;
90b. Note that these feed rollers 90a and 90b each have an idle roller 9.
2a and 92b are in contact with each other.

Here, the three separation belts 82a mentioned above.

82b and 82c are positioned at the upper, middle, and lower portions of the outer peripheral surface of the feed drum 30, respectively. Moreover, the rotation support shaft 86 mentioned above has three separation belts 82a and 82b.

82c are in close contact with the outer circumferential surface of the feed drum 30 and the corresponding separation rollers 84a, 84b, and 84c, respectively, and apply sufficient tension to the feed drum 30 to similarly run in accordance with the rotation of the feed drum 30. Separation rollers 84a, 84b.

84c by the distance necessary to feed the feed drum 30.
It is separated from.

Further, this rotation support shaft 86 starts from the second idle roller 36b in the separation position, and the separation belt 82a,
82b and 82c are separated from the outer peripheral surface of the feed drum 30, and this second idle roller 36b and
Separation belts 82a, 82b up to the rotation support shaft 86,
A portion 82c is set to constitute a part of the conveyance path 18 described above.

In this way, by arranging the three separation belts 82a, 82b, and 82c around the feed drum 30, the lottery tickets W fed to the separation position are separated by these separation belts (which run in synchronization). 82a, 82b, 82
c, it is peeled off from the outer circumferential surface of the feed drum 30, and is then sent out toward the conveyance mechanism 20 in accordance with the running of the separation belts 82a, 82b, and 82c.

Here, the conveyance speed VH in the conveyance mechanism 20 and the feed speed V2 in the feed mechanism 16 (that is, the same as the feed speed in the separation feed mechanism 80) are defined as follows: Even if the numbers are fed consecutively, it is possible to separate them by a sufficient distance on the conveyance path 18 so that the number recognition and inspection device 22 can read them in a state in which they are recognized from each other. In order to make this possible, it is set so that V14>vr.

As a result, unless equal consideration is given, the leading end of the lottery ticket W is transported by the transport mechanism 20, and the rear end is transported by the separation feeding mechanism 8.
0, and based on the speed difference between the two, this treasure ticket W is subjected to stress in the direction of tearing, and in the worst case, it may actually tear.

Therefore, in this embodiment, as shown in FIG. 8, separation rollers 84a are adjacent to each other.

Feed rollers 90a, 90b are arranged between 84b, 84c, and the radius of each feed roller 90a, 90b is set to the radius of each separation roller 84a, 84b, 84c, so that the corresponding separation belts 82a, 82b, 82c The feed rollers 90a and 90b are configured to be attached to the rotation support shaft 86 via corresponding one-way clutches 88a and 88b, respectively. ing.

In particular, each one-way clutch 88a, 88b has a rotary support shaft 86 attached to a feed roller 90a, 90b in a counterclockwise direction.
When a faster rotational force is not acting, the rotation support shaft 86 and the feed rollers 90a, 90b are connected to rotate together, while the feed roller 90 is rotated counterclockwise.

The feed rollers 90a and 90b are configured to be allowed to rotate idly with respect to the rotation support shaft 86 when a rotational force faster than the rotation support shaft 86 is applied to the rotation support shaft 86.

Since the separating and feeding mechanism 80 is configured in this way, as shown in FIG. 9A, the tip of the lottery ticket W is
In the state where the feed drum 30 is not brought to zero, the feed drum 30 is
Separation rollers 82a, 84b, 84 rotated in synchronization with
With the rotation of the rotation support shaft 86 to which C is fixed, the feed rollers 90a and 90b are rotationally driven via one-way clutches 88a and 88b, respectively.
0a, 90b and the corresponding idle rollers 92a
, 92b, the lottery ticket W is in a state where it is connected and clamped by,
It will be sent at a speed of Vy.

On the other hand, as shown in FIG. 9B, when the leading edge of the lottery ticket W is brought to the conveying mechanism 20, the leading edge of the lottery ticket W is conveyed by the conveying mechanism 20 at a speed VW. As a result, the feed rollers 90a and 90b are rotated by the lottery ticket W fed at this speed VH, and are rotated at a peripheral speed faster than the rotation support shaft 86 via the one-way clutches 88a and 88b, respectively. Become.

In this way, the lottery ticket W as a whole is sent at the speed VH, and the risk of it being torn is completely eliminated.

In this way, in the separating and feeding mechanism 80 of this embodiment, the fed lottery ticket W is completely peeled off from the feed drum 30, and at a conveying speed VH faster than the feeding speed V here. This separated lottery ticket W can be fed into the conveyance mechanism 20 while absorbing these speed differences without tearing the lottery ticket W.

Next, referring again to FIG. 2, the above-mentioned transport mechanism 20

Here, a first endless belt 98a is wound around the entrance roller 94a and the exit roller 96a located on the negative side, and the large mouth roller 94b and the exit roller 96 located on the other side are wound.
A second endless belt 98b is wound around b. And these first and second endless belts 98a.

The above-mentioned conveyance path 18 is defined between the mutually opposing surfaces of 98b.

Further, a drive mechanism 100 is connected to the exit roller 96a located on the - side, and this drive mechanism 100 drives the lottery tickets W brought to the rollers 94a and 94b for both people.
The first endless belt 98a is configured to be driven so as to be transported along the transport path 18 at a transport speed VH.

Specifically, this drive mechanism 100 includes a drive motor 100a
Then, the driving force of this drive motor 100a is transferred to the exit roller 96.
A pair of endless belts 1oob, 1 sequentially transmitting data to a
00c, and a brake mechanism 100d that can arbitrarily apply a brake to one endless belt 100b.

Next, regarding the number recognition inspection device 22, FIG.
This will be explained with reference to FIGS. 10 to 12.

This number recognition inspection device 22 is arranged so as to be located on the other side of the conveyance path 18, as shown in FIG. Particularly, in this embodiment, for the purpose of improving reading accuracy, this number recognition inspection device 22 has three types of number G.
Three pickup mechanisms 102, 104, and 106 are provided for reading R, SQ, and BF exclusively.

And these three pickup mechanisms 102°104
．． 106 are conveyed along this conveyance path 18 based on the read information read by each person.

In addition to recognizing BF, checking the continuity of lottery numbers SQ,
Then, the character quality of each number GR, SQ, BF is inspected for irregularities, stains, missing parts, etc., and when focusing on one lottery ticket W, the B font number BP is Number G
Inspection unit 108 that is obtained from R and the lottery number SQ by a predetermined function conversion and inspects whether the number is uniquely determined or there is a relationship.
It is connected to the.

Here, these pickup mechanisms 102°104.10
6 are arranged sequentially along the conveyance path 18, and the pick-up mechanism 102 at the right end in the figure, that is, the entrance side, is used exclusively for reading the lottery number SQ printed on the lottery ticket W. The pickup mechanism 104 is
The pick-up mechanism 106 on the left end in the figure, that is, on the exit side, is arranged to exclusively read the B font number BF printed on the lottery ticket W. It is set up.

Note that the arrangement order of the pickup mechanisms 102, 104, and 106 is set so that the order of importance for number recognition is high.

Here, each of the pickup mechanisms 102, 104 and 106 has the same configuration, which reduces the time required to process the information read by these pickup mechanisms 102, 104, and 106, and improves the structural arrangement efficiency. Taking this into consideration, these are arranged adjacent to each other along the transport direction. As a result, as will be described later, each pickup mechanism 1
The image sensors (line sensors) made up of CCD sensors provided at 02° 104 and 106 are arranged at equal distances from each other in the conveyance direction.

On the other hand, as shown in FIG. 10, the height positions of the pickup mechanisms 102, 104, and 106 are independently defined. That is, as described above, the lottery ticket W conveyed through the conveyance path 18 is in an upright position, and as is clear from FIG. The height from the bottom edge to the center position is H1
゜Ha, H3 are set differently, and in detail, the center position in the height direction of the image sensor of each pickup mechanism 102, 104, 106 and the center position in the height direction of the corresponding numbers GR, SQ, BF are set as follows. They are set to match each other.

Next, the configuration of each of the pickup mechanisms 102, 104 and 106 will be explained, but in the following explanation, since these pickup mechanisms have the same configuration, only the pickup mechanism 102 for reading the lottery number GR will be explained as a representative. However, descriptions of the other pickup mechanisms 104 and 106 will be omitted with similar subscripts.

That is, as shown in FIG. 11, this pickup mechanism 1
02 is a light source unit 102a and a sensor unit l
02b and a read timing detection sensor 102c, this light source unit 102a is
02 a r, the light source lamp 1102a housed in this housing 102 a +, and this light source lamp 1
The lens 102a s directs the light emitted from O2a□ toward the lottery number SQ to be read.

The sensor unit 102b also detects the lottery ticket W being transported.
The housing 102bl is disposed opposite to the travel route of the lottery number SQ printed on the housing 102b, and the housing 102b
, a lens 102 attached to a portion facing the traveling path of
b a, an image sensor 1o2ba for receiving reflected light and reading an image thereof, and this image sensor 1
02bi is attached to the sensor board 102b.

Here, the image sensor 102b is composed of a line sensor formed by arranging 64 pixels in a line, and the range read by the 64-pixel image sensor 102ba is from the focal length of the lens 102ba to the image sensor 102bl. By appropriately specifying the distance to the lens 102bl, etc., the number height of the lottery number SQ can be set to y, treasure (
If the height from the lower edge of the ticket W to the center position of the lottery number SQ is H2, the reading range is set to be Hm±y. That is, the reading width is set to be limited to twice the number height.

In this way, for example, if you pay attention to the lottery number SQ,
The unit that reads this lottery number SQ is limited to the pickup mechanism 102, and other pickup mechanisms 104,
106 cannot read this lottery number, and this pickup mechanism 102 cannot read other numbers G.
This means that R and BP cannot be read.

As a result, in this embodiment, only the dedicated pickup mechanism 102 is used when reading the lottery number SQ, and this pickup mechanism 102 obtains the maximum resolution when reading the lottery number SQ. It can be uniquely set so that it can be used, thus greatly improving the overall reading accuracy.

Here, the above-mentioned read timing detection sensor l 0
2c is arranged at a position where the tip of the lottery number SQ is turned on by the tip of the treasure ticket W on which the lottery number SQ is printed, when the tip of the lottery number SQ is conveyed to a position exactly facing the pickup mechanism 102. The pickup mechanism 102 is connected to the read timing detection sensor 10.
When 2C is turned on, a predetermined pickup operation is started and a number is read.

In addition, as shown in FIG. 12, the above-mentioned inspection unit 108 includes recognition units 108a, 1108a, 108a that recognize numbers based on the detection information picked up by each pickup mechanism 102, 104, and 106.
s, a registration unit 1 in which shape patterns of group number GR1, lottery number SQ, and B font number BF are registered in advance.
08bl, 108b2.108ba and each recognition unit 10
The shape patterns of the numbers recognized by 8a+, 108i, and 108as and the corresponding registration units 108b, 108b2
, 108bS, a comparison unit 108c+, 108c2.108 that compares the shape pattern of the number already registered with the shape pattern of the number.
ca, and a quality inspection unit 108d that inspects character quality such as irregularities, dirt, and missing characters in numbers based on the results of comparison in each comparison unit 108c.

108dz and 108d3.

On the other hand, this inspection unit 108 uses a setting section 108e that sets an arbitrarily set start number as a start number in the continuity test on the operation panel P, and a counter function in the eccentricity 1 detection mechanism 64 described above, to sequentially
A counter section 108f that increments the number by 1 from the number in the setting section, and a recognition section 108 that recognizes the lottery number SQ.
A comparison section 108g compares the lottery number recognized by the a + with the number counted by the counter section 108f, and based on the comparison result of this comparison section 108g, it is determined whether the numbers read according to the conveyance order have continuity. A continuity test section 108h is provided to test whether or not the data is present.

Furthermore, this inspection unit 108 includes a calculation unit that calculates the two numbers recognized by the recognition unit 108aa, which recognizes the group number GR, and the recognition unit 108a+, which recognizes the lottery number SQ, based on a predetermined function. 1081, and a comparison unit 108j that compares the number recognized by the recognition unit 108 a s that recognizes the B font number BF with the number calculated by the calculation unit 1081, and based on the comparison result of this comparison unit 108j, this A relevance testing section 108 that tests whether the three types of numbers printed on the lottery ticket W have a predetermined relationship is equipped with.

Then, the inspection results at the relevance inspection section 108, the inspection results at the continuity inspection section 108h, and the inspection results at the quality inspection section 108d described above are used to print It is set to be output in the state printed on the bag ff1I.

In this way, for example, when a series of conveyance operations is completed, if there is a problem with the quality of the characters such as unevenness, dirt, or missing characters in the number, the quality inspection units 108d, 108d,
, 108d, it is determined that there is a quality problem, and a message to that effect is displayed. As a result, the lottery tickets W in the take-out stocker mechanism 24 are taken out, subjected to manual re-inspection, and a final judgment of acceptability is made.

Furthermore, if a number jump occurs, the numbers after the number where the number jump occurs are stored in the counter section 108.
Since it no longer matches the count value at f, all the numbers after this number jump occur are checked by the continuity check section i o
sh will determine that there is no continuity, and a message to that effect will be displayed. Furthermore, if a control error or printing error occurs in the printing device that prints the treasure ticket W, and the three types of numbers have no relationship with each other, the relationship inspection unit 108 determines that there is no relationship. and a message to that effect will be displayed.

In addition, during transportation, the lottery tickets W whose three types of numbers GR, SQ, and BP printed on the surface have been recognized and inspected are brought to the takeout stocker mechanism 24, where they are accumulated. You will have to wait. Incidentally, since the configuration of this take-out stocker mechanism 24 is well known, its explanation will be omitted.

The processing operation of the treasure ticket W in the treasure ticket processing device 10 configured as described above will be explained below.

First, before starting the actual processing operation, 1. As described above, the eccentricity and amount of the feed drum 30 are measured.

That is, in a state where the lottery tickets W are not being fed, the feed drum 30 is rotated idly, and the three suction hole groups 38a,
The eccentricity of the foot drum 30 at 38b and 38c is measured, and the values are stored in the storage circuit 74.

After the amount of eccentricity is stored in this way, the actual processing operation is performed. Here, assuming a case where a thin normal room ticket Wl is to be processed, first, when an instruction is given to load a treasure ticket W on the operation panel P, the biasing mechanism 32 is activated in the feed stocker mechanism 14. The AC torque motor 32a biases the pressing member 28 in the direction away from the feed drum 3o, thereby securing a large loading space.
A predetermined number of 1 sheets, for example 500 sheets, are loaded in one bundle.

Thereafter, on the operation panel P, the first lottery number SQ for starting the process is set, the thickness to be processed is set to 80 um in the thickness setting mechanism 56, and the start button is pressed. In this way, the processing operation is started.

As the start button is pressed, first, in the feed stocker mechanism 14, the AC torque motor 32a biases the pressing member 28 in a direction approaching the feed drum 30, and as a result, the loaded treasure ticket W, comes into contact with the feed drum 30 at a predetermined pressure at the take-out position.Meanwhile, in the drive mechanism 34 of the feed mechanism 16, the drive motor 34a is also activated to drive the feed drum 30 to rotate at a predetermined rotational speed. In addition, the vacuum pump 42
is activated to generate negative pressure in the suction hole groups 38a, 38b, and 38c located at positions that avoid the wind shield member 4.4.

As a result, the food drum 3 rotating at the take-out position
The treasure (Jiken W) that is in contact with the outer peripheral surface of 0.

By bringing the suction hole group 38a to this take-out position, the lottery ticket W is attracted by negative pressure and taken out from the feed stocker mechanism 14 as the feed drum 30 rotates. Here, even if two lottery tickets W1 are taken out from this take-out position, the gap between the feed drum 30 and the reverse roller 50 is kept at a constant reference gap amount by the double feed prevention mechanism 46. Therefore, only one lottery ticket W1 that is in close contact with the outer circumferential surface of the feed drum 30 cannot pass between the reverse roller 50 and the second lottery ticket W1, which is in close contact with the outer peripheral surface of the feed drum 30. When the tip is in contact with 50, feeding becomes impossible, and in this way, double feeding is reliably prevented.

On the other hand, the lottery ticket W that has passed between the reverse roller 50
1 is the first idle roller 36 of the eccentricity detection mechanism 64;
a is biased radially outward while passing between this and the feed drum 30 and fed to the separation position.

Here, as described above, the first idle roller 36a
By biasing the feed drum 30 outward in the radial direction, the presence or absence of double feed is determined and the number of sheets passed is counted based on the wear of the feed drum 30.

Then, the treasure ticket W1 fed to the separation position is peeled off from the outer peripheral surface of the feed drum 30 by the separation feed mechanism 80, and the three separation belts 82a, 82b, 82
As the roller c travels, the rollers 90a, 90b and the idle rollers 92a, 92b are sent to the contact portion with each other.

Here, this treasure ticket W1 is conveyed at the speed V, as described above, until the leading end is conveyed by the conveyance mechanism 20, and in reality, it is conveyed in synchronization with the feed drum 30. A one-way clutch 88a is attached to a rotation support shaft 86 that is rotationally driven by running separation belts 82a, 82b, and 82c.

A feed roller 90a connected via 88b.

90b is rotating to achieve a speed V.

Then, the tip of the treasure ticket W is held between the entrance rollers 94a and 94b of the conveyance mechanism 20, and is conveyed at this speed 2 by the endless belts 98a and 98b running at the speed v0.

Here, as described above, the speed VH in the conveyor +fl120 is the speed v in the feed mechanism 16.

As a result, the second lottery ticket, which was taken at the take-out position but whose double feed was prevented by the double feed prevention mechanism 46, is set to be faster than the previously fed lottery ticket. Even if they are continuously fed, based on this speed difference, the two will be sufficiently separated by the separation feeding mechanism 80. In this way, the number recognition test operation in the number recognition test device 22 will be performed. Sufficient processing time will be secured.

On the other hand, in the separation feeding mechanism 80 as described above, only the leading end of the lottery ticket W1 is fed at a high speed VH.

88b begins to spin idle, and the rear part of this lottery ticket Wl is not restrained at the slow speed V (, the lottery ticket W1 as a whole is sent at a fast speed ■). , in this separating feed mechanism 80, this lottery ticket W is transferred to the conveying mechanism 20 which conveys at a faster conveying speed VH.
1, but this speed difference is definitely absorbed,
Tearing, tearing, etc. of the lottery ticket W1 due to the speed difference can be reliably prevented.

In this way, the treasure ticket W1 that is transported alone in a sufficiently drawn state with the subsequent lottery ticket W by the transport mechanism 20 is checked by the number recognition inspection device 22.
The three types of numbers SQ, GR, and BF printed on the surface are read, and specifically, the three types of numbers SQ.

GR and BF will be read by the three corresponding pickup mechanisms 102, 104, and 106, and the reading accuracy will be greatly improved.

Thereafter, when subjected to a predetermined recognition test operation by the number recognition test device 22, this treasure ticket W1 is transferred to the exit roller 96.
a, 96b, and are discharged to the take-out stocker mechanism 24, where they are accumulated in the reading order. Then, the treasure accumulated in the feed stocker mechanism 14 (
When all the same tickets WI are fed, subjected to a recognition inspection operation by the number recognition inspection device 22, and accumulated in the takeout stocker mechanism 24, a series of processing operations is completed.
The processing results are output in a printed state on the printing device I.

In addition, in the continuity test in this recognition test operation,
As mentioned above, since the double feed prevention mechanism 46 reliably prevents the lottery ticket W1 from being double fed,
A highly accurate continuity check will be performed.

As described in detail above, the lottery processing device 1 according to an embodiment of
0 is equipped with the gap amount regulating mechanism 52 having the above-mentioned configuration, so that the gap amount can be accurately defined according to the thickness of each room lottery ticket W, and double feeding can be reliably prevented. Become.

This invention is not limited to the configuration of the one embodiment described above (it goes without saying that various modifications can be made without departing from the gist of the invention).

For example, in the above-described embodiment, even if it is found that the continuity of the lottery numbers SQ is disrupted, the operation of conveying the treasure ticket W is continued to the end,
Although it has been described that the printing device I displays a message to that effect after the conveyance operation is completed, the present invention is not limited to such a configuration, and can be used at the time when a quality problem is found, or when a continuous When it becomes clear that sexuality is being inhibited,
As soon as the lack of relevance is found, the conveying movement is stopped and
Needless to say, the system may be configured to clearly indicate the abnormal state to the operator.

Furthermore, in the embodiment described above, the counter section 108
Although the counter function of the eccentricity detecting mechanism 64 has been described as being used for the count-up at the beginning, it may also be performed by software every time the number reading operation is completed.
