Abstract

PURPOSE:To change the transferring direction of sheets of paper with high speed by locating switch pieces and guide pulleys such that the forward and backward angular displacement of the switch pieces accompanying the rotation of a rotary shaft is regulated by guide pulleys. CONSTITUTION:When switch pieces 62, 63 are rotated by a certain angle, they reach barrel portions of guide pulleys 34n1, 34n2 to be stopped thereby. Since then a large distance between a rotary shaft 61 of the switch pieces 62, 63 and guide pulleys 34n1, 34n2 at the stopping positions is provided, impact forces received by a separator 44 and guide pulleys 34n1, 34n2 are small. Also, since the rotary shaft 61 is located near the bottom surface of a triangular space 50, a leading end or the like of a sheet of paper being carried does not collide with the rotary shaft 61 even if it is broken, but advances along the surfaces of the switch pieces 62, 63.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a paper sheet sorting device that can selectively change the conveyance direction of paper sheets being conveyed by a belt at high speed.

[Technical background of the invention and its problems]

For example, data cards and paper sheets from banks are usually stored in stacks, and such paper slips are classified by information field or by predetermined number of sheets. K takes out the paper sheets one by one and sends them to the conveyance path, and on the way to this conveyance path, reads the IN11II class information and counts the number of sheets passing through. It is necessary to switch the transport direction of a predetermined number of IIK sheets and stack them again in a stacked state.

As a method for conveying the paper ms+, there is a belt conveyance method in which the paper products drawn out one by one are held between a pair of belts running in contact with each other and conveyed to a predetermined position. Conventionally, in order to switch the conveyance direction of paper sheets conveyed according to the above-mentioned request using belt conveyance, the following configuration is most commonly adopted. That is, in the middle of the conveyance path, the conveyor belts, which are running in contact with each other, come out of contact and run with a skirt-like spread. Two guide pulleys are provided inside this conveyor belt that spreads out in a skirt shape, and each of the two guide pulleys separately contacts with each belt of the pair of conveyor belts that spreads out in a skirt shape, respectively. A belt is wound around the belt to form a first path and a second path. In the approximately triangular space formed by the conveyor belt and the two guide pulleys, there is a separator that is angularly displaced in the forward and reverse directions around an axis parallel to the axis of the guide pulley. The configuration is such that This separator is shaped like a triangular prism with triangular sides, and when a switching command signal is sent to the separator, the sand stop rotation is reversed, and one side of the separator and a skirt-like expansion are connected to one side of the conveyor belt forming the paper. A gap is formed between the conveyor belt and the paper products are conveyed within this gap. Then, it is fed into a conveyance path where one of the conveyor belts is in contact with a conveyor belt wound around a guide pulley located on the other side of the separator, where it is held and conveyed to a predetermined position. Conventionally, a rotary lenoid or a motor capable of forward and reverse rotation has been used as a drive source for angularly displacing the separator in forward and reverse directions. A rotary lenoid uses a linearly moving lid lenoid and mechanically converts it into rotational motion. When using this method, one is to use an OK spring to obtain reversal, and the other is to use a pair of rotary linoids that operate in the same way coaxially and integrally connect one solenoid to the other solenoid. There is one that obtains forward and reverse rotation by exciting it. Using a motor capable of forward and reverse rotation, an external stopper is provided to obtain a constant angular displacement of the separator, and forward and reverse positioning is performed by hitting the arm attached to the rotating shaft against the stopper. .

The paper *@ sorting device having the above-mentioned configuration has the following disadvantages because the separators are positioned by displacing the separators at a certain angle.

■ Papermaking with many parts, very complex structure and high cost ^
I'm smiling. In other words, in a drive source that uses a rotary lenoid, a spring or an additional spring is used for forward and reverse rotation.
The number of parts increases, such as the need for a rotary linenoid of 1,000,000,000,000,000,000,000,000,000,000,000,000,000,000000000000000000000000000000000000000000000000000000000,000,000,000,000,000,000,000,000.

■Secondly, separators have the disadvantage of poor high-speed response for forward/reverse switching. With spring type motors, the spring force is always acting in one direction, so if the spring is used to achieve reverse rotation, extra force must be generated to overcome this spring force during forward rotation, resulting in poor high-speed response. Become.

If a pair of rotary linoids is used, the solenoid becomes larger and the rotating part becomes longer (twice as long), which increases the weight of the rotating part and increases the moment of inertia.

In addition, when a forward/reverse motor is used, an arm attached to the rotating shaft for positioning is required, so this increase in weight is also due to an increase in the moment of inertia. This is a major obstacle to increasing the speed of separators.

(2) Furthermore, due to the structure of (2) which increases the force or weight applied to the shaft, the power supply capacity increases in all rotary shaft drive systems. In particular, with the solenoid ring type, the solenoid cannot maintain its position unless it is energized for an amount corresponding to the spring force, which can lead to problems with heat generation, and the rotating shaft vibrates at the end of the operation and takes time to dampen the vibration. It takes a while to set the position accurately.

■ In addition, the nine K models use a forward-reverse motor and position the arm attached to the rotating shaft by hitting it against the stopper. If the stopper or arm is damaged, or the arm is made of a special material, or the vibrations that occur during a collision do not subside, the separator cannot be positioned accurately, and the separator is formed on the same side of the conveyor belt. The electric path has become unstable and it has entered! There are drawbacks such as the paper leaves hitting the vibrating separator and causing jams. Furthermore, since the structure of the separator is approximately triangular prism-like, the separator has a large inertia, which is a major factor in increasing speed.

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and its purpose is to provide a paper sheet sorting device that can change the conveyance direction of paper sheets being conveyed by a belt at high speed. be.

[Summary of the invention]

According to the present invention, the ninth and first guide pulleys are provided facing each other in the middle of the conveyance path, the conveyor belts are guided by the guide pulleys, and then leave contact with each other and travel with a skirt-like spread, and the skirt A second guide pulley located inside the conveyor belt that spreads in a shape, and this second guide pulley IJK! A belt that forms a pair with a conveyor belt that is hung and spreads like a skirt to form a separate conveyance path, and a second conveyor belt that forms a pair that spreads like a skirt.
a switching piece provided in a space formed between the first and second guide pulleys and angularly displaced in the forward and reverse directions around an axis parallel to the axes of the first and second guide pulleys; When the separator is angularly displaced in one direction or the other direction, one end of the separator is stopped by a part of the first guide pulley, thereby positioning the angularly displaced separator.

Moreover, the cross section of the above separator is approximately the shape of the alphabet 'A'.
'' shape, and consists of a plurality of switching pieces fixed integrally at the center of the rotating shaft.The motor that drives this switching piece has a permanent magnet on the rotor with a part of the magnetic am having low magnetic resistance. is used.

By configuring the paper sheet sorting device as described above, the number of parts in the device can be kept to the necessary minimum, and the separator is locked using the tip of the separator itself, so the following method can be used. effective.

■ Movable parts such as the stopper arm that moves in unison with the separator are no longer required, making it possible to create a structure in which only a separator is added to a single motor, reducing the weight of the movable parts and enabling high-speed response. . As a result, the operation time of the seven pallets is shortened, and (4) when the belt conveyance speed is kept at the conventional speed, the pitch of the paper industry is increased by increasing the number of sheets per unit time for feeding between the belts. It is now possible to classify the paper industry even if the sheets are packed together and conveyed, and the paper sheet conveyance density is high, and the processing capacity of paper sheets in the standard time is improved. When the pitch is set to 9, unlike the conventional method, paper slips can be sorted even if the conveyance speed is increased, and this has the effect of improving the throughput of paper slips per unit time.

■ The distance between the locking position and the center of rotation of the separator can be effectively increased, reducing the impact force received by the locking members (separator and first guide pulley) that lock the separator due to the rotational torque of the separator including the motor rotor. It can be made smaller, has higher reliability, and has a longer lifespan.

■ Separator rotation (b) The rotating shaft can be kept sufficiently away from the surface of the separator through which the paper passes, so that even if the leading edge of the paper being transported is torn, the separator rotation axis is located at the part where the separator or rubber protrudes. This prevents jamming from occurring.

■ The distance between the first guide pulley and the second guide pulley can be reduced (if the separator size is the same as before, the first guide pulley can be shifted to the second guide pulley). Since we will be placing the
This is due to the fact that the distance that the paper is guided by the separator becomes shorter, and even if the paper sheet being conveyed is very weak, it is guided by the separator and decelerated. The generation of folded leaves at the tips of leaves can reduce the S* of jam generation to almost zero.

Furthermore, in addition to these effects, a forward-reverse rotation motor is used to drive the separator, and a permanent magnet is used in the rotor, so the motor itself locks when the separator is locked with the first guide pulley. Because it has the torque to hold the position,
Even if the motor is not energized, or even if it is energized, the locking position is reliably maintained with only a very small current flowing, so it is possible to save power and take into account the problem of heat generation in the motor. There is also the effect that speeding up can be achieved without any problems.

Further, each of the switching pieces 62 and 63 is fixed by a connecting portion 64 in a positional relationship such that the switching pieces 62 and 63 are moved in parallel on the rotating shaft 61 to which the switching pieces 62 and 63 are fixed, and this connecting portion 64 is fixed to the rotating shaft 61. ing. Switching piece 62.6
3 is made of a material with low specific gravity and low coefficient of friction, such as a processed product such as resin. As shown in FIG. 4, the drive motor 60 has a rotary shaft 61 connected thereto, and has nine rotors 70 made of permanent magnets. Pole magnetic pole 71.
72 and is surrounded by nine stators 73.

The magnetic poles 71 and 72 K are each wound the same number of times in the same direction, and nine coils 74 and 75 are connected in series, with a DC power supply circuit 7 at both ends.
6 is connected. That is, the coils 74 and 75 are wound so that when energized, magnetic poles 71 and 72 generate magnetism with the same polarity. The rotating shaft 61 is composed of a permanent magnet and is rotated by the attraction and repulsion between the nine rotors 70 and the generated polarity of the magnetic poles 71.72K. If the direction of the current flowing through the coils 74 and 75 is changed, magnetism with the opposite polarity is generated in the magnetic poles 71 and 72, and the rotating shaft 61 rotates in the opposite direction. That is, since the magnetic poles 71 and 72 are provided at opposing positions on the stator 73, when the coil is not energized, the magnetic poles of the permanent magnet are provided on the stator 73, and when the coils are not energized, the magnetic poles of the permanent magnets are placed in the stator 73, and when the magnetic poles 71 and 72 are opposed to each other, an attractive force is generated when the coils are not energized. Since the rotational torque of the rotor 70 becomes the maximum, the rotational torque of the rotor 70 becomes the minimum, and the rotor 700 rotations stop at this position. In other words, the rotating shaft 61 has two resting positions facing the magnetic poles 71 and 72 and dead opposite to each other. When the rotating shaft 61 rotates between these two points, the rotor 70 rotates with a torque characteristic curve as shown in FIG. This rotational torque reaches its maximum when the rotational shaft 61 makes a half turn from one stationary position to the other stationary position and passes through the midpoint of the rotation angle. It is positioned so that The passing point of this maximum torque is located on the line connecting the center of the rotating shaft 61 and the contact point of the bells 31m and 31b of the space 50.

According to the present invention, when the rotating shaft 61 rotates, the nine switching pieces 62 and 63 formed integrally therewith also rotate. When the switching pieces 62.63 are rotated in one direction or the other, the tips of the switching pieces 62.63 are rotated into the above-mentioned position as shown in FIGS. 7 and 8. J
34nx or pulley 34 position 3 is arranged in such a relationship that it makes contact with one part of the other. Switching piece 62.63
is locked by either the pulley 34fi1 or the pulley 34al, and rotation of the rotating shaft 61 is restricted. At this time, even if the current flowing through the coil 74.75K is cut off, the magnetic attraction force of the permanent magnet is still working, so the switching piece 62.63 is held stationary at the position where it is locked by the pulley 34n1 or pulley 34fil. The DC power supply circuit 76 has a circuit as shown in FIG. That is, 80 is a DC power supply, and the collector sides of + side K NPN transistors 81 and 82 of this power supply are connected in parallel. This transistor 81.8
The emitter sides of the transistors 2 are further connected to the collector sides of H transistors 83 and 84, respectively, and the emitter sides are connected to the one-way terminals of the cutting conductor 8o. The respective transistors 81 and 82
．． Diodes 83 and 84 are connected to diodes 88a, sob, 88c, and 88d such that a DC power supply applied between the collector and emitter is applied with a reverse bias. The nine coils 74. connected in series are connected between the emitters and collectors of the transistors 81.
75. and transistor 81
．． A control signal from a gate circuit 85 is supplied to the base of transistor 84, and a control signal from gate circuit 86 is supplied to the bases of transistors 82 and 83. For example, when a control signal is received from the detection section 49 of the paper industry provided in the conveyance area of conveyance bells 31m and 31b in FIG. A good signal inverted by an inverter 87 is supplied to the circuit 86, and the signal is supplied to the transistors 82, 84 through the inverter 87, so that the transistors 81.
82, 83, and 84 are controlled to be conductive or non-conductive in a predetermined mode to energize the pulley.

Next, the operation of the good paper sheet sorting apparatus constructed as described above will be explained with reference to the operational waveform diagram of FIG. 6 and FIGS. 7 and 8.

Let us now consider the aspect of driving the motor 42, pump 23, 28 and compressor 26. In this state, due to the action of the permanent magnet 70 attached to the rotating shaft 61 of the motor 60, the switching pieces 62 and 63 are rotated to one side as shown in FIG. side a2
The tip of b (63b) is stuck in the snow of guide boo 934m and is stationary. Now, the paper sheets X are stacked on the paper form mounting table 17 while the machine is stationary as shown in FIG. Then, the drive motor 42 and the compressor 2 are operated from an operation section (not shown).

The lifting of the mounting table 17 is carried out at the upper part thereof, and the paper sheet positioning is performed by a Mitswitch, thereby also positioning the top layer of the stacked paper sheets X. The uppermost sheet of paper @Y of the positioned paper M@X is intermittently sucked by the suction nozzle 22 housed inside the rotary drum 18 every time the suction holes 20a, 20b of the rotary drum 18 arrive. 31 m,
It is fed into the polymerization section of 31b. Then, when the leading edge of the paper sheet just reaches the belt O polymerization part 5, rotating drum 1
The suction of the paper industry by 8 is released, and due to the movement friction between the conveyor belt and the paper sheets, the paper sheets are taken into the overlapping part of bells) 31m and 31b and travel. By repeating this operation intermittently and continuously, the paper sheets X stacked on the mounting table 17 are continuously taken out.

After passing through the detection unit 49 and reaching the position of the separator 44, the paper sheet Y enters the triangular space 50, thereby making the leading end free. However, the paper sheet Y whose leading edge has become free tries to move forward in the conveying direction due to pushback, but the leading edge of the paper m5iy is stuck on one side 6 of the switching piece 62.
