Here, another sheet-like conveyed article 2 whose bar code faces the back and cannot be read is inverted by the reversing device 20 and the bar code faces the obverse and is conveyed on the second belt conveyor 1b. Then, the belonging data is read by the second barcode reader 40b to identify the belonging data. The identified thin plate-like conveyed material 2 is sorted by a predetermined sorting unit and discharged from the dispensing device 27 by type.

Next, a description will be given of a dispensing device of a sorting section for dispensing sheet-like conveyed materials sorted by type with reference to FIGS. 8 and 9. FIG. The payout device is denoted by reference numeral 27, and the payout device 27 is provided at predetermined intervals downstream along the transport direction of the second belt conveyor 1b so as to carry out the identified thin case 2 by type. A discharge conveyor 29 such as a roller conveyor, for example, is installed to be inclined downward in correspondence with these dispensing devices 27, and accommodates the thin case 2 by type at the downstream side of the discharge conveyor 29. Various storage trays 30 are arranged so as to be able to be taken out.

More specifically, the dispensing device 27 is disposed behind the lower end guide member 16 having an L-shaped cross section, which is attached along the longitudinal direction of the support frame S which supports the lower edge of the inclined belt support plate 12 of the belt conveyor 1b.

A plate-shaped rotating arm 36 is mounted on the output shaft of the rotary actuator 34 inserted from the lower surface of the bracket 32. The rotating arm 36 is usually parallel to the inclined belt support plate 12 of the belt conveyor 1b. It is configured to face the downstream side in such a state, and to penetrate outward through the insertion port W of the support surface 16b of the lower end guide member 16 parallel to the belt support plate 12 at the time of rotation.

Next, the operation of each device constituting the sorting system for the thin plate-like conveyed product will be described according to the flow of the thin case.

First, the separation and supply device 3 shown in FIG.
When b passes above a small-diameter roller R, which is a rotating member that is driven in reverse rotation in conjunction with a feed member (not shown), the supporting member H is supported by a holder H that has been transferred to an upper portion of a transport device 5b disposed therebelow. Is done.

Subsequently, the rear thin case which is conveyed in close contact with the cutting-edge thin case 2b to be separated has a small diameter whose bottom surface is driven to reverse just before the leading thin case 2b is separated. It comes into contact with the outer periphery of the roller R, and a frictional force causes a rearward acting force, so that the roller R is reliably separated from the thin plate-like case 2b.

The thin plate-like case 2c at the end, which is separated from the intermittent transfer device 5a and supported on the holder H of the transfer device 5b, is placed on the surface of the first belt conveyor 1a on which the belt 4 is mounted at a predetermined interval. When supplied one by one, the bottom surface of the thin plate case 2 is supported on the flat belt B2 of the alignment device 18.

In this case, when the thin plate-like case 2 is supported on the flat belt B2 in an inclined posture, the posture is corrected by the speed difference between the belt 4 of the first belt conveyor 1a and the flat belt B2, The lower end is supported by the upper surface of the lower end guide member 16 and the rear side sandwiching the corner is locked by the partition 9 of the belt 4 and is conveyed downstream.

The rectangular thin case 2 in which the front and back sides are mixedly placed on the belt 4 of the first belt conveyor 1a is the only one in which the bar code is conveyed face up and the first bar code reader 40a. The attribute data by the bar code unique to the thin case is read, and the thin case 2 with the bar code facing the back is placed in the first bar code reader 4.
In case of 0a, reading is impossible, so that the sheet passes through the sheet as it is and is conveyed to a reversing device described later on the downstream side.

Next, the operation of the reversing device 20 will be described with reference to FIG.

The thin case 2 that has reached the reversing device 20
The lower end is held by the transfer holding member 25 of the reversing device 20, and the side surface of the thin plate-like case 2 is pressed by the pressing lever 32 a to be sandwiched between the side wall 26.

Subsequently, when the thin plate-like case 2 accommodated in the transfer holding member 25 is detected by a detecting device (not shown), the step motor M is rotated by a predetermined angle (60 degrees) according to this detection signal.

As described above, the thin plate-shaped case 2 is
When the belt 4 is supported and conveyed on the mounting surface of the belt 4 inclined in a direction perpendicular to the conveying direction of the belt conveyor 1a, the second belt conveyor 1b inclined at a symmetric angle with respect to the first belt conveyor 1a by the reversing device 20. Is supported on the mounting surface of the belt 4.

When the transfer holding member 25 of the reversing device 20 is rotated by 60 degrees, the contact portion 32 at the other end of the pressing lever 32a is turned.
When b contacts the roller 35a of the stopper 35, the pressing lever 32a is opened against the urging force of the tension spring 34 by the rotational force of the rotating disks 24a and 24b.

The thin plate case 2 in which the pressing lever 32a is released and becomes free is supported on the belt 4 of the second belt conveyor 1b in an inclined state, and is conveyed downstream by the second belt conveyor 1b. Immediately thereafter, the unique belonging data is read by the second barcode reader 40b.

As described above, the attribute data unique to the thin case 2 is stored in the first bar code reader 40 a before and after the reversing device 20.
Alternatively, when the image is read by the second barcode reader 40b, the sheet is conveyed on the second belt conveyor 1b and discharged from a predetermined sorting unit arranged on the downstream side by a dispensing device.

In the payout device 27, when the predetermined thin plate case 2 read and identified by the first barcode reader 40a or the second barcode reader 40b reaches the corresponding payout position, the rotary actuator 34 is activated. As a result, the rotation arm 36 is rotated via the output shaft, and protrudes from the insertion port W of the support surface 16b.

Thus, the identified thin case 2
The pivot arm 36 pushes this downward from the back side toward the front, is discharged to the outside via a predetermined carry-out conveyor 29, and is securely stored in the dedicated storage tray 30.

Next, the sorting control of the various cases 2 will be described in detail with reference to FIG.

That is, on the downstream side of the second belt conveyor 1b, a plurality of sorting units S1, S2,
S3, S4, and S5 are arranged, and these sorting units S1, S5

Are sequentially counted from the detection device n1, and when the thin plate-like conveyed object 2 of the belonging data K2 is counted by n2 in the process of being conveyed on the second belt conveyor 1b, the sorting unit corresponding to the instruction from the control device U The dispensing device 27 of S2 is operated, and the sheet-like conveyed material 2 of the belonging data K2 is dispensed from the sorting unit S2.

On the other hand, when the first bar code reader 40a detects the passage of the sheet-like conveyed object 2, if the bar code faces the back side and the recorded information of the bar code is not read, the sheet-like convey Only the passage of the object 2 is detected, the arithmetic processing is performed by the control device U, and the barcode is turned upside down by the reversing device, and the second barcode reader 40b
At the time of reading at the time of reading, the sheet-like transported material 2 of the belonging data K1
Is confirmed.

As described above, in the control device U, the sorting units S1 to S5 for sorting the various sheet-like articles 2 are calculated based on the belonging data K1 to K5 read by the first and second barcode readers 40a and 40b. When the thin plate-like conveyed object 2 is sequentially detected by the detecting device n from the point of time when the second bar code reader 40b reads it, and the n-th detecting device corresponding to the belonging data detects the thin plate-shaped conveyed material 2 Thus, a desired sheet-like conveyed article 2 can be paid out from the corresponding sorting section.

In this way, the belonging data K1, K2, K3, K4, and K5 unique to the sheet-like conveyed article 2 are read,
Based on the data stored in the control device U, the counters n1, n2, and n of the detection device up to the corresponding sorting unit are set based on the time when the data passes through the second barcode reader 40b.
3, n4 and n5 are counted, and the sheet-like conveyed article 2 corresponding to the belonging data is discharged from the corresponding sorting section.

Therefore, the first bar code reader 40a on the upstream side of the reversing device 20 and the second bar code reader 40b installed on the downstream side of the reversing device 20 allow either one of the front and back sides of the rectangular thin plate-shaped conveyed object 2 to be moved. Data K1 recorded in
To K5 are continuously read in any of the first and second belt conveyors 1a and 1b in the conveying process, and the read thin plate-like conveyed articles 2 are sequentially sorted from the sorting unit. The sorting of the conveyed articles 2 can be performed reliably and quickly.

Further, when the rectangular thin plate-like conveyed objects 2 separated one by one are transferred onto the conveying surface, they are locked to the partitioning portions 9 at predetermined intervals, so that the separated one-by-one sheets are separated. And the belonging data K of the sheet-like conveyed material 2
1 to K5 are reliably read, and can be easily sorted.

Further, the reversing device 2 between the opposing surfaces of the first belt conveyor 1a and the second belt conveyor 1b.
0, the first and second belt conveyors 1 facing each other.
Since the operation is controlled so as to start and stop in synchronization with the conveyance of a and 1b, when the thin sheet-shaped article 2 is transferred onto the conveyance surface, it is locked to the partition section 9 at predetermined intervals, so that
It can be transported reliably in a state where each sheet is partitioned,
