Further, in the conveying path 3 on the downstream side of the reading section 4,
A sorting unit 11 is provided as a sorting device having a large number of sorting boxes 6 prepared according to the address information of the mail.
The sorting unit 11 has sorting transport paths 5a to 5g extending horizontally in a plurality of stages (A to G), and below each sorting transport path, a plurality of sorting boxes arranged along the lower surface side thereof. 6 are provided. Each of the divided conveyance paths 5a to 5g is connected to the conveyance path 3 via the stepped path unit 10. In addition, this stage pass section 1
0 is provided with a gate for sorting the conveyed postal matter to the respective sorting and conveying paths 5a to 5g, and each sorting box 6 is provided with a gate communicating with the corresponding sorting and conveying path. Therefore, the postal matter P conveyed through the conveying path 3 is branched into any one of a plurality of stages (A stage to G stage) according to the sorting destination code, and is placed in a predetermined sorting box 6. It is designed to be collected separately.

A conveyance detector group (not shown) for detecting the conveyance of the postal matter P on the conveyance path is provided on the conveyance paths 3 and 5a to 5g. When a large number of postal items are supplied to the automatic postal item sorting device configured as described above and the postal item sorting operation is started, the postal items taken out from the accommodation unit 1 by the take-out device 2 are conveyed by the transport mechanism 30. Is conveyed to the reading unit 4 via the conveyance path 3. The mail is the reading part 4
When the mail is conveyed to, the address information is read from the mail, the sorting destination code corresponding to the address information is output, and the mail is conveyed to the sorting unit 11. The postal matter conveyed to the sorting unit 11 is sorted into predetermined stages by the stage pass unit 10 according to the sorting destination code, and is sorted and collected in a predetermined sorting box 6.

Next, the above-mentioned take-out device 2 will be described in detail with reference to FIG. The take-out device 2 has a supply section 21 as a supply means for supplying the postal matters P having various lengths and accommodated in the accommodating section 1 in an upright state with their rear ends aligned to a predetermined take-out position. The supply unit 21 has a horizontally extending reference surface 21a that abuts the rear ends of the mail items P so that they are in contact with each other and aligned.
And a moving mechanism 21b as moving means for moving the postal matter P aligned in the standing position with respect to the reference surface 21a in the surface direction. The moving mechanism 21b includes a spring 14 whose one end is fixed, and a pressing plate 16 which is fixed to the other end of the spring 14 and extends along the surface of the postal matter P. Therefore, the frontmost leaf of the postal matter P (hereinafter referred to as the frontmost postal matter P1) is always arranged at the take-out position where it comes into contact with the take-out belt described later.

At this take-out position, a take-out belt 22 which is endlessly conveyed in a direction (upward in the drawing) substantially orthogonal to the reference surface 21a is arranged. The take-out belt 22 has a plurality of suction holes (not shown) arranged side by side in the transport direction. The take-out belt 22 is stretched around a driving roller 23 and two driven rollers 24a and 24b, and the driving roller 23
Is connected to a motor 25 of variable rotation speed. A motor controller 26 for controlling the rotation speed of the motor 25 is connected to the motor 25, and a CPU 29 as a control unit is connected to the motor controller 26. Motor controller 26 and CPU2
Reference numeral 9 constitutes a changing means of the present invention for changing the rotation speed of the motor 25. Therefore, the take-out belt 22 can travel at a variable speed in the direction (upward in the drawing) away from the reference surface 21a at the take-out position.

Inside the take-out belt 22, there is provided a main suction portion 27 which is sucked by the suction pump 12 while being adjacent to and facing the inner surface of the take-out belt 22. The suction pump 12 and the main suction unit 27 constitute the suction means of the present invention. The main suction portion 27 has a suction opening 27 a on the side facing the inner surface of the take-out belt 22. Therefore, when the hole of the take-out belt 22 is moved to a position corresponding to the opening 27a, the negative pressure by the main suction portion 27 acts on the postal matter P so that the postal matter P is attracted to the take-out belt 22 and the take-out belt 22 The postal matter P is taken out upward in the figure as the vehicle travels. The main suction unit 27 and the suction pump 1
2 together with the take-out belt 22, the drive roller 23, and the motor 25 constitute the take-out means of the present invention.

When the frontmost postal matter P1 placed at the take-out position is taken out as described above, the second postal matter P2 is moved by the moving mechanism 21b and placed at the take-out position. Two
The first piece of postal matter P2 is taken out in the same manner as the frontmost postal matter P1 when the next hole moved along with the traveling of the take-out belt 22 is moved to a position which coincides with the opening 27a of the main suction portion 27. To be done. In this way, the postal matter P supplied to the take-out position by the supply unit 21 is sequentially taken out as the take-out belt 22 travels.

Further, below the driven roller 24b in the vicinity of the take-out position outside the take-out belt 22, an auxiliary suction section 28 for sucking by the suction pump 12 is arranged. The auxiliary suction section 28 is provided with a suction opening 28a opened toward the rear end of the postal matter P arranged at the take-out position, and generates a weaker suction force than the main suction section 27. The auxiliary suction unit 28 acts so that the take-out belt 22 does not take out two or more postal matter P at a time. That is, the first postal matter P1 is sent upward by the strong suction force of the main suction section 27, and at this time, the suction force of the auxiliary suction section 28 acts near the rear end of the second postal matter P2. do it,
The second postal matter P2 is prevented from being moved together with the first postal matter P1.

The postal matter P taken out by the take-out belt 22 is conveyed by the conveying mechanism 30 toward the subsequent processing device through the conveying path 3. That is, a pair of conveyor belts 31 and 33 forming the conveyor path 3 are provided at the position where the postal matter P is received on the downstream side of the take-out device 2. The conveyor belt 31 is wound around the rollers 32 a and 32 b, and the conveyor belt 33 is wound around the rollers 34. The conveyor belts 31 and 33 are each driven at a constant speed by a drive mechanism (not shown). Therefore, when the front end of the taken out postal matter P is moved to the take-in position Q where the conveyor belts 31 and 33 overlap, the postal matter P is pinched between the conveyor belts 31 and 33, and thereafter, these conveyor belts 31 and 33 are conveyed. Three
The sheets 1 and 33 are conveyed at a constant speed through the conveying path 3 and are guided to the subsequent processing device.

The distance from the reference surface 21a to the pick-up position Q is set to a value that can reliably convey the shortest mail P. In addition, the take-out device 2 forms a light source 41 that irradiates the surface of the postal matter P, which is supplied with its rear end aligned by the supply unit 21, with planar light, and an image of the planar light formed on the surface of the postal matter P. An area image sensor 42 that receives an image and forms a two-dimensional image. The plane light is a light beam that extends in the length direction of the postal matter P in a plane substantially perpendicular to the reference plane 21a and advances straight in a plane. These light sources 41
And the area image sensor 42 acts as a measuring means for measuring the length of the mail P.

As shown in FIGS. 3 and 4, the light source 41 is arranged at a position slightly deviated from the front position of the postal matter P in the width direction of the postal matter P and is inclined with respect to the surface of the postal matter P. It is designed to irradiate plane light from. The plane light from the light source 41 crosses the front end of the postal matter P so that the postal matter P
To the surface area of the. Area image sensor 42
Is arranged substantially in front of the surface of the postal matter P and at a position where the reflected light from the postal matter P can be received as a two-dimensional image. The area image sensor 42 analyzes the two-dimensional image detected by the area image sensor 42, calculates the length of the mail piece based on the analysis result, and outputs a control signal to the motor controller 26 based on the calculation result. A CPU 29, which acts as a generating means, is connected.

Next, the operation of taking out the postal matter P in the above-mentioned taking-out apparatus 2 will be described with reference to the block diagram shown in FIG. In the state where the negative pressure by the main suction unit 27 is not applied to the postal matter (the hole of the take-out belt 22 is not positioned at the opening 27a of the suction unit 27), the frontmost postal matter P1 is taken out by the supply unit 21. When it is supplied to
Is measured (step 51). The length of the postal matter P1 is measured by the method described later using the light source 41 and the area image sensor 42.

When the length of the postal matter P1 is measured, the take-out speed of the postal matter P1, that is, the rotation speed of the motor 25 is set in the CPU 29 according to the measurement result (step 52). This take-out speed is set so that the distance between the rear end of the postal matter P0 conveyed before the postal matter P1 and the leading end of the postal matter P1 is constant. For example, when the length of the postal matter P1 is relatively short, the take-out speed is set relatively high, and when the length of the postal matter P2 is relatively long, the take-out speed is set relatively slow.

When the rotation speed of the motor 25 is set,
The motor controller 26 controls the rotation speed of the motor 25 to a set value, and the traveling speed of the take-out belt 22 is controlled (step 53). When the hole of the take-out belt 22 is located at the opening 27a of the main suction portion 27,
The postal matter P1 is adsorbed to the take-out belt 22 and the postal matter P1 is taken out at the set take-out speed (step 54).

The postal matter P1 taken out is conveyed through the conveying path 3 and the postal matter P2 in the second row is taken out by the same method as the movement of the next hole of the take-out belt 22. Therefore, the intervals between the mail items P are always kept constant.

The method of measuring the length of the postal matter P will be described below. When the plane light emitted from the light source 41 is applied to the front end region of the postal matter P, the plane light is diffused and reflected on the surface of the postal matter P, and the reflected light is detected by the area image sensor 42. In this case, the plane light is applied to an area including at least the tip of the shortest mail item and the longest mail item. The detected reflected light is analyzed as follows, the tip position of the postal matter P is calculated, and the length of the postal matter P is measured.

For example, as shown in FIGS. 3 and 4, when the length of the front mail piece P1 is shorter than the length of the second mail piece P2, the two-dimensional image detected by the area image sensor 42 is As shown in FIG. 6, the postal matter P1 is discontinuous at the position corresponding to the leading end thereof. That is, 2
Since the stacked mail pieces have steps, the light source 4
The plane light from 1 is irradiated near the front end of the front mail piece P1, and the plane light passing above the front end of the mail piece P1 is irradiated on the second mail piece P2 beyond the mail piece P1. It In addition, since the plane light is radiated obliquely, the spot position of the plane light seen from the front of the postal matter P is the postal matter P1.
There is a deviation in the width direction of the postal matter P with the tip end of the postal matter in Sakai. Therefore, the two-dimensional image obtained by the area image sensor 42 has the above-mentioned discontinuity at the position corresponding to the leading end of the postal matter P1.

By calculating the position of this discontinuity point, the position of the tip of the postal matter P1 is calculated. The rear end of the mail piece contacts the reference surface 21a, and its position is always constant. Therefore, the length of the mail piece P1 can be calculated from the position of the front end portion.

When calculating the position of this discontinuity, that is, the position of the leading edge of the mail P1, the two-dimensional image data detected by the area image sensor 42 is filtered as shown in FIG. An image of a flat plane light is extracted (step 61). Next, this image is divided into horizontal pixel columns of the area image sensor 42, and n
The inclination of the straight line connecting the center of the image of the first column and the center of the image of the (n + 1) th column is calculated (step 62). This inclination is sequentially calculated from the lowermost pixel row of the area image sensor 42. Then, it is determined that the position where the calculated slope changes most greatly compared to the slope calculated immediately before is the discontinuous point (step 63). The rear end of the postal matter P1 is the reference plane 21.
The area image sensor 4 is aligned by abutting on a.
Since 2 is arranged at a predetermined height position with respect to the mail P, if the position of the discontinuity is determined, the mail P1
Is measured (step 64).

The method of measuring the length of the postal matter P1 when the length of the frontmost postal matter P1 is shorter than the length of the second postal matter P2 has been described above.
The length of the mail piece P1 can be measured even when there is no longer mail piece, that is, when the mail piece P1 is the longest and when the mail piece P1 is the last leaf. In this case, the image of the plane light is monitored from the lowermost pixel row of the area image sensor 42, and the position where this image is interrupted is determined to be the front end of the mail P1.

When the two-dimensional image obtained by the area image sensor 42 has a plurality of discontinuities, the plane light image is similarly monitored from the pixel row at the lowermost end of the area image sensor 42, and this image is first displayed. The discontinuous position is determined to be the leading end of the postal matter P1.

As described above, according to this embodiment, the postal matter P1 before the frontmost postal matter P1 supplied to the take-out position is taken out.
The length of 1 can be measured, and based on this length, the take-out speed of the postal matter P1 can be set in advance so that the interval with the previously conveyed postal matter P0 is constant. Therefore, unlike the conventional take-out device, it is possible to control the take-out speed at the same time as the start of taking-out, without starting the control of the take-out speed in the middle of taking out the mail. Therefore, the postal matter can be taken out at a higher speed, and the postal matter can be sorted at high speed.

The present invention is not limited to the above-described embodiments, but can be variously modified within the scope of the present invention. For example, any means may be used to detect the front end position of the postal matter, as long as the front end position of the frontmost postal matter P1 supplied to the take-out position with its rear ends aligned can be detected.

[0036]

As described above, since the paper sheet take-out device of the present invention has the above-described structure and operation, the paper sheet can be taken out at a higher speed.
