Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mail sorting machine for automatically sorting postcards and envelopes, and more particularly to a device for removing envelopes in which metal pieces or the like are enclosed or envelopes having a thickness exceeding a specified value. It is possible to remove an abnormal mail item without affecting the conveyance of the mail item having no abnormality.

[0002]

2. Description of the Related Art A postal sorter sorts postal items based on the postal code written on a postcard or a letter of seal. The postal code is read directly from the postal item and sorted according to the identified postal code. A method has been developed in which a bar code corresponding to a postal code is read in advance and the bar code is read from a postal matter to be classified.

The bar code in the latter method is a bar code (stealth bar code) invisible to the mail when the sender visually prints on the mail to be sent and when the postal code of the mail is read in the post office. ) May be printed, and the sorting machine is equipped with a reader that reads a visible bar code and a reader that reads a stealth bar code by irradiating ultraviolet rays to read the code of the mail. There is.

The mail items to be sorted are sandwiched between belts and conveyed one by one in the sorting machine. As shown in FIG. 15, for example, one of the belts 11 is suspended from a drive wheel (drive pulley) 13 and a plurality of pulleys (pulley) 15, and the other belt 12 is a drive wheel 14 and a plurality of pulleys. Suspended in 16. The belt 11 and the belt 12 are in contact with each other in a part of the section, and the section in contact with each other serves as a conveyance route of the mail. The shafts of the driving wheels 13 and 14 penetrate to the back surface of the substrate, and the driving force of the motor 34 is transmitted to the shafts to drive the driving wheels 13 and 14.
14 rotates, belt 11 is driven by drive wheel 13,
12 is driven by a drive vehicle 14 so as to move in the same direction in the transport section, and is sandwiched between the belt 11 and the belt 12 to transport the postal matter.

The postal matter conveyed by the conveying path of the belt 11 and the belt 12 is conveyed by the conveying path formed by the belt 18 and the belt 19 as shown in FIGS. 15 and 16, or at this time. When the traveling direction is changed by the sorting means 17, the sheet is conveyed on the conveying path formed by the belt 11 and the belt 10, and further, as shown in FIG.
And is conveyed on the conveyance path formed by the belt 72.

[0006] As described above, the mail items are successively passed through the conveyance paths formed by the belts and moved in the sorting machine. In the process of the conveyance, the bar code of the mail item is read and the identified bar code is obtained. On the basis of this, it is distributed to the corresponding mouth of the stacking unit having a plurality of sorting mouths.

[0007] However, if a letter, a nail, or the like is enclosed in the letter, or if the letter has a considerable thickness, the mail is deformed along the curve of the conveyance path formed by the belt. It becomes impossible to push the belt, and the belt is pushed open, which causes troubles such as hitting the pulley to stop the movement and breaking the belt. In order to avoid such accidents, the sorting machine detects envelopes in which metal of a specified length is enclosed or envelopes with a thickness not less than specified at the initial stage of transporting mail items, and normalizes these abnormal items. It is guided to the branch road from the transportation route of and removed.

Conventionally, in order to remove this abnormal mail,
As shown in FIG. 17, a metal detection device 74 and a thickness detection device 73 are arranged in the conveyance path of the postal matter 70. The metal detecting device 74, as shown in FIG.
Metal sensors 74a and 74b arranged in two rows with a space of 0 mm.
Is equipped with. Further, three metal sensors are arranged in each row so that the metal can be detected at any position in the width direction of the postal matter 70 in which the metal advances, so that the metal can be detected. When the metal sensors 74a and 74b arranged in two rows detect the metal at the same time, it is considered that the mail 70 has a metal of more than 40 mm, and the mail is rejected.

The thickness detecting device 73, as shown in FIG.
A roller 73a that rolls in contact with the mail 70 (or the belt 11 along the mail 70) and a support piece 73 that supports the roller 73a.
c, a rotary shaft 73b that supports the support piece 73c, and a rotary shaft 73b.
Angle detector 73d for detecting the rotation angle of the.
In this device 73, the rotary shaft 73b rotates according to the thickness of the mail piece 70, and the thickness of the mail piece 70 is detected from the rotation angle.

The postal matter in which the metal exceeding 40 mm is detected or the postal matter having a thickness exceeding the regulation is then sorted by a sorting means.
The conveying direction is switched to the B direction by 75, and the conveying direction is eliminated through the branch path. Other normal mail items go straight in the direction A, and the next processing is performed.

[0011]

However, in the conventional apparatus for removing abnormal postal matter, the abnormal postal matter before being discharged is caught on the belt or pulley of the conveying path to stop the movement or to be separated from the conveying path. There has been a problem that the transportation of mail is interrupted each time an accident occurs that prevents the normal mail from proceeding.

[0012]

[0013]

The present invention solves these conventional problems, and does not affect the normal conveyance of mail items,
It is an object of the present invention to provide an abnormal postal matter removing device that can reliably remove an abnormal postal matter.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 3 (a) is a top view of a mail sorting machine equipped with the abnormal mail removing device of the present invention, and FIG. 3 (b) is a front view thereof. Further, FIG. 4 shows a housing structure in which the cover, door, outer wall, legs and the like of this mail sorting machine are removed.

A large number of mail items to be sorted are arranged in alignment with the supply unit 20 shown in FIG. 3, sequentially transferred to the left side of the drawing, taken in part by part in the apparatus, and conveyed in the apparatus by a belt. . Dotted lines in FIGS. 3 (a) and 3 (b) schematically show the conveyance route of the postal matter. The postal matter taken into the apparatus is first conveyed upwardly, and in the process of the upward conveyance, the abnormal postal matter removing device of the present invention is used for a sealed letter containing metal of a predetermined length or more and a thickness of more than a specified thickness. The envelope is detected and eliminated.

Next, the postal matter transferred to the horizontal conveyance turns and passes in front of the bar code reader 21 for visible code and the bar code reader 22 for stealth, and the bar code is read. Next, in the elevator section 23 having a spiral descending conveyance path, the elevator section 23 is lowered to the stage to be sorted, and then conveyed to the stacking section 24.

The stacking unit 24 is divided into three stages, and in the example of FIG. 3, each stage is provided with 11 division ports. The mail items horizontally moving in the stacking unit 24 are sorted into the respective sorting ports based on the barcode reading result, and are collected there.

The housing of the sorting machine is constructed by combining a plurality of modules as shown in FIG. That is, the barcode readers 21, 22 and the control unit module 26 that is the housing of various control devices 29, the elevator module 27 that is the housing of the elevator unit 23, and the stacking unit module 28 having the sorting port are combined, and integrated. The module 28
3 stages × 3 modules with 3 division ports and 3 stages ×
One module having two division ports is connected.

In the control unit module 26, a base 30 on which a pulley and a drive wheel of the ascending / conveying unit 25 for ascending and conveying the supplied mail is attached is attached to the frame body so as to have an inclination of 15 degrees. This inclination is provided in order to bring the bottom of the postal matter, which is clamped by the belt and conveyed upward, into contact with the base 30 to stabilize the attitude of the postal matter with respect to the belt.

FIG. 1 shows the base 30 removed from the frame. Further, FIG. 2 is a top view of the base 30.

The abnormal mail removing device of the present invention is embodied in the base 30.

On one surface of the base 30, a metal detector 31 for detecting the metal enclosed in the sealed letter in addition to the drive wheel and the pulley.
, A thickness detector 32 for detecting the thickness of the sealed letter, a sorting unit 17 for switching the conveyance route of the mail, and a hood 33 for accepting abnormal mail containing metal or too thick.
And are installed.

The ascending transport route is the drive wheel 13, pulley 15, pulley
Endless belt 11 suspended on 15a and pulley 15b, and endless belt 12 suspended on drive wheel 14, pulley 16 and pulley 16a.
2, as shown in FIG. 2, the endless belt 19 suspended by the drive wheel 41, the pulley 42, the pulley 42a, and the pulley 42b, the endless belt 18 suspended by the pulley 44, the drive wheel 43, and the pulley 45. It is formed of an endless belt 10 suspended.

All the postal items are conveyed upward in the conveying path formed by the belt 11 and the belt 12, and in this conveying process,
An abnormal mail piece is detected by the metal detector 31 and the thickness detector 32. The sorting unit 17 switches only the advancing direction of normal mails without hindering the progress of abnormal mails. As a result, the abnormal mail piece rises straight, is caught in the conveyance path formed by the belt 19 and the belt 18, and is conveyed to the hood 33.

As described above, since the delivery of the abnormal postal matter having poor flexibility is carried out linearly between the conveying routes, the abnormal postal matter can be smoothly relayed. It is possible to suppress the occurrence of accidents that are caught on the belt.

As shown in FIG. 5, a pulley 42b for suspending the endless belt 19 at the entrance of the hood 33 has a support shaft 50 pivotally supported by the base 30, and the pulley 42b rotates about the support shaft 50. It is possible to move. Further, in the arc-shaped conveyance path formed by the belt 19 and the belt 18, the pulley 44 is arranged on the belt 18 side which is the inside of the arc, but the pulley 19 is arranged on the belt 19 side which is the outside of the arc.
No pulley is placed between 42a and pulley 42b. Therefore, the belt 19 can freely deform outside the arc. The movability of the pulley 42b and the degree of freedom of the deformation of the belt 19 enable smooth conveyance of an abnormal postal matter having a poor flexibility on a curved path. Further, even if the belt 19 is largely deformed during this conveyance, it does not adversely affect the route of normal mail.

As shown in FIG. 6, a hole 35 is formed at the position of the hood 33 of the base 30. If the abnormal postal matter is hood 33.
The inner surface of the dust chute 82 is discharged from the hole 35, slides on the inclined surface of the dust chute 82, and accumulates in the receiving portion arranged below. As shown in FIG. 7 (a) (view from the back side of the base 30) and FIG. 7 (b) (view from the front side of the base 30), the inner surface of the hood 33 has a hole 35 for the bounced mail. There is a wall 47 that is angled toward the hole 35 and a floor surface 48 that is inclined toward the hole 35.
The mail is guided to the dust chute 82.

On the other hand, normal mail is sorted by the sorting unit 17
The traveling direction is changed by and is captured by the transport path formed by the belt 11 and the belt 10 and transported to the next elevator module 27. A normal mail piece is more flexible than an abnormal mail piece and can sufficiently cope with a change in traveling direction.

Further, in this apparatus, as shown in FIG.
Two driving motors 34 and 46 are installed on the back surface of the base 30, the driving wheels 13 and 14 are driven by the motor 34, and the driving wheels 41 and 43 are driven by the motor 46. Therefore, even if an accident occurs in the conveyance route of the abnormal postal matter formed by the belt 19 and the belt 18 and the motor 46 stops, the driving force of the remaining motor 34 causes the conveyance route of the belt 11 and the belt 12, In addition, the normal postal matter can be continuously conveyed by the conveying path of the belt 11 and the belt 10.

In addition, all of the conveying paths formed by the belt 11 and the belt 12 must be moved upward even if the postal matter is thick. Therefore, the entrance of the transport path formed by the pulleys 15a, 15b, and 16a is formed by the pulleys 15a, 15b, and 16a so that the mail sent from the supply unit 20 can be reliably chucked even if it is thick. The receiving guide angle is set wide, and the standing position of the pulley 15b for chucking is made movable.

8 (a) (top view) and FIG. 8 (b) (side view) show the relationship between the pulley 15a and the pulley 15b.
Further, FIG. 9 shows a mounting state of the pulleys 15a and 15b as viewed from the back side of the base 30. The pulley 15a and the pulley 15b are connected by a connecting piece 51, and the pulley 15a is a connecting piece.
The pulley 15b is rotatably fixed to one end thereof, the pulley 15b has its rotating shaft fixed to the center of the connecting piece 51, and the other end of the connecting piece 51 is provided with one end of a spring 52. In addition, the base 30 is provided with a long hole 53 for fixing the rotary shaft of the pulley 15a, and the rotary shaft of the pulley 15b is inserted therethrough.
The other end of 52 is fixed. Therefore, the connecting piece 51 and the pulley 15
b can rotate about the pulley 15a as a fulcrum, and the range of this rotation is limited by the long hole 53 through which the rotating shaft of the pulley 15b is inserted.

The pulley 15b normally stands at a position where the tension of the spring 52 and the tension of the belt 11 are balanced, but when a thick mail piece is supplied, the pulley 15b resists the spring 52 depending on its thickness. Go back and make sure to chuck the mail. When the mail passes, it is returned to its original position by the force of the spring 52.

Although the chucking mechanism is provided on the belt 11 side here, a similar mechanism may be provided on the belt 12 side. Further, the movable mechanism of the pulley 15b may have the same structure as that of the pulley 42b (FIG. 5), and a spring force may be applied to the structure.

FIG. 10 shows a perspective view of the metal detecting device 74 fixed to the base 30, and FIG. 11 shows the metal detecting device 74 removed from the base 30. This device 74
L-shaped mounting member 54, and 1 for this L-shaped mounting member 54
It is composed of three metal sensors 55 arranged in a row, and the end surface of the metal sensor 55 is exposed from the belt contact surface of the mounting member 54.

Each metal sensor 55 detects the presence / absence of metal at each position of the postal matter passing in front (detection based on the presence / absence of eddy current), and when the metal is enclosed in the postal matter, the metal is detected. The electric signal that is turned on only during the period of detecting is output to the control unit. The control unit counts the number of pulses (1 pulse = 1 ms) while the metal sensor 55 is on,
When the number of pulses exceeds a certain value, the sorting unit 17 is controlled so that the mail piece is identified as an abnormal mail piece and enters the conveyance path formed by the belt 19 and the belt 18. The control of this control unit will be described later.

In this metal detecting device 74, the metal sensor 55 is
Since only the rows are arranged, the size can be reduced.

FIG. 12 is a perspective view of the thickness detecting device 73 fixed to the base 30, FIG. 13 is a top view (a) and a side view (b) of the thickness detecting device 73, and FIG. 14 is a base.
The thickness detection device 73 removed from 30 is shown.

The thickness detecting device 73 includes a movable portion 56 that moves when a mail piece has a predetermined thickness or more, a stopper portion 57 that restricts the movement of the movable portion 56, and a detection portion that detects the movement of the movable portion 56. 58 and.

The movable part 56 includes a roller 59 that rotates in contact with a mail piece or a belt, a rotary plate 60 to which the roller 59 is fixed, a rotary shaft 61 of the rotary plate 60, and a light blocking piece that blocks the light of the detection part 58. 62 and
A spring locking portion 63 that locks the spring 64 and a contact protrusion 65 that contacts the stopper portion 57 are provided.

Further, the detecting portion 58 has an L-shaped mounting member 66.
The photodetector 67 is attached to the photodetector 67, and the photodetector 67 includes a protruding piece 68 to which a light emitting element is attached and a protruding piece 69 to which a light receiving element is attached. The light blocking piece 62 of the movable portion 56 moves between the two. Further, the stopper portion 57 includes a stopper member 80 that abuts on the abutting protrusion 65 of the movable portion 56, and a spring.
And a spring locking portion 81 for locking 64.

In this thickness detecting device 73, the protrusion amount of the stopper member 80 is adjusted so that a predetermined dimension (5 mm) is maintained between the roller 59 of the movable portion 56 and the surface of the belt 11. If a mail piece with a thickness exceeding this size passes, the belt will
Since it cannot bulge toward the metal detection device 74 side, only the roller 59 side swells according to the thickness of the mail piece. Therefore, the roller 59 contacts the belt 11 or mail and
59 and the rotary plate 60 rotate around the rotary shaft 61 against the spring 64 in accordance with the movement of the mail. When the rotary plate 60 rotates, the light-shielding piece 62 fixed to the rotary plate 60 becomes a protruding piece of the detection unit 58.
Escape from between 68 and protruding piece 69. Therefore, the light of the light emitting element reaches the light receiving element, and the signal is sent to the control unit.

In response to this, the control unit discriminates the postal matter as an abnormal postal matter, and controls the sorting unit 17 so as to enter the conveyance path formed by the belt 19 and the belt 18 at a timing described later. .

When the postal matter passes, the roller 59 and the rotary plate
The spring 60 returns to the original state by the force of the spring 64. Along with this, the light blocking piece 62 enters between the protruding piece 68 and the protruding piece 69 of the detection unit 58 and blocks the light of the light emitting element.

In this thickness detecting device 73, the displacement of the roller 59 is detected by the movement of the light shielding piece 62 which is located at a distance from the center of rotation. Therefore, it is possible to detect the thickness with high precision while having a simple structure.

Further, passage sensors (optical sensors) for detecting passage of mail are installed at positions N0.1 and N0.2 in FIG. 2 in the conveying path formed by the belt 11 and the belt 12. The operation timing of the sorting unit 17 depends on the metal detector.
It is controlled by the control unit based on the detection result of the thickness detector 32 and the thickness detector 32 and the detection result of the passage sensor.

This passage sensor, as shown in FIG.
Two passage sensors (sensor A (N0.1 in FIG. 2) and sensor B (N0.2 in FIG. 2)) are installed at a distance slightly shorter than the length of a normal envelope. The detector 32 is 10 m from the sensor A located at the rear in the transport direction.
It is arranged at a position closer to the sensor B side by m.

The timing chart of FIG. 21 shows the relationship between the detection period of the passage sensor and the metal detector and the operation of the rotary solenoid that drives the distribution unit 17. The rotary solenoid is turned on when normal mail is sorted, and turned off when abnormal mail is sorted.

First, the sensor A detects the envelope being conveyed, and when metal is enclosed in this envelope, one of the three metal detection sensors arranged vertically detects a foreign substance. Although the position where the metal enters the envelope is indefinite, if the metal detection sensor detects the metal while the sensor A is detecting the envelope, the metal is sealed in the envelope.

When the metal detection sensor detects metal and turns on, the control unit counts the number of pulses (1 pulse = 1 ms). When the number of pulses exceeds a predetermined value, the envelope is an abnormal mail item. To identify.

When the envelope is identified as an abnormal mail item,
After a lapse of a certain time from the time when the sensor B detects passage of the envelope and is turned on, the rotary solenoid of the sorting unit is turned off to secure a path for removing abnormal mail.

Then, after a lapse of a certain period of time from the time when the sensor B is turned off, the rotary solenoid is turned on to secure the conveyance route of the normal mail.

Further, even when the thickness detector 32, which detects the thickness at substantially the same position as the metal detector, detects an abnormal postal matter, the detection results of the sensors A and B are used in exactly the same manner as in the rotary of the sorting unit. The solenoid is controlled.

In this case, the sensor B is placed to check the passage time of the postal matter which has been detected by the metal detector and the thickness detector. However, only the sensor A is used as the passage sensor and the sensor A is used. It is also possible to control the turning on / off of the rotary solenoid based on the turning-off time of.

[0061]

As is apparent from the above description, the abnormal postal matter removing device of the present invention is provided with a receiving guide angle at the entrance of the conveying route for receiving the supplied postal matter, and
Since the standing position of the pulley that is responsible for chucking is variable, you can reliably chuck even thick mail,
It can be sent to the detector.

Further, since the abnormal postal matter having poor flexibility is delivered straight between the conveying paths, it is possible to suppress the occurrence of accidents.

Further, since no pulley is arranged outside the arc in the arc-shaped conveying path for conveying the abnormal mail item so as to allow the deformation of the belt, an accident in which the abnormal mail item is caught on the pulley can be prevented. it can.

Further, the respective conveying paths are arranged so as not to affect the conveying path of the normal mail even if the belt of the arc-shaped conveying path is deformed, and the drive source of the conveying path of the normal mail is abnormal. Since the drive source of the mail delivery route is separate, abnormal mail can be removed by another route without hindering the delivery of normal mail.

Further, since the abnormal postal matter conveyed by another route is discharged from the back of the base using the dust chute, the abnormal postal matter can be discharged without affecting the conveyance of the normal postal matter. is there.

[0066]

[0067]

Therefore, the apparatus for removing abnormal mail according to the present invention is
Abnormal mail can be reliably removed without affecting the normal conveyance of mail.
