FIG. 1 shows an internal configuration of a printer processor having a sheet sorting apparatus according to the present invention. The printer processor 10 includes a printer 11 and a processor 12. The printer 11 includes a magazine 15, a cutter 16, a back printing unit 17, an exposure unit 18, and a sorting unit 19. The photosensitive material 20 set in the magazine 15 is cut by the cutter 16 according to the print size, and becomes a cut sheet-like photosensitive material 20a. The photosensitive material 20a is transported toward the exposure unit 18 along a transport path 21 indicated by a two-dot chain line in the drawing, and a frame number, correction data, and the like are printed on the back surface of the photosensitive material 20a by the back printing unit 17 along the way. Is done. Then, the exposure unit 18 exposes and records an image based on the image data on the light receiving surface of the photosensitive material 20a. Thereafter, the exposed photosensitive material 20 a is distributed to a plurality of columns such as two or three by the distribution unit 19 and sent to the processor 12.
[0014]
The processor 12 includes a development processing unit 25, a drying unit 26, a swing back unit 27, and a sorter unit 28. The development processing unit 25 includes a developing tank, a bleach-fixing tank, and first to fourth washing tanks, and a transport rack is attached to each tank. The transport rack transports the photosensitive material 20a into each tank, and performs development, bleach-fixing, washing with water, and the like. The developed photosensitive material 20 a is dried with hot air in the drying unit 26. Thereafter, the photosensitive material 20a that has been transported in a plurality of rows is returned to the first row in the exposure order by the swing-back unit 27, and sent to the sorter unit 28 from the discharge port 27a. For this reason, a discharge roller pair 29 is disposed at the discharge port 27 a, and the photosensitive material 20 a is discharged by the rotation of the discharge roller pair 29. As shown in FIG. 4, the discharge roller pair 29 is rotationally driven by a motor 30. The rotation of the motor 30 is controlled by the controller 43 via the driver 30a.
[0015]
As shown in FIGS. 2 and 3, the sorter unit 28 includes a rectangular thin plate-shaped frame 31, three endless conveyor belts 32a to 32c arranged in the longitudinal direction of the frame 31, and edge alignment. It consists of flappers (sheet transfer members) 33a and 33b, edge alignment guide members 34a and 34b that also serve to prevent dropping, and a detachable stopper 35. Reference numeral 36 denotes an attachment recess formed in the frame 31, and the frame 31 is fixed to the processor 12 by an attachment screw 37 through the attachment recess 36.
[0016]
The three conveyor belts 32a to 32c are arranged at the central portion and both sides thereof, and can cope with a plurality of types of photosensitive materials having different width sizes. A small-sized photosensitive material having a small width is received by only one central conveying belt 32a. Further, a medium-sized or large-sized photosensitive material having a large width is received by the three belts 32a to 32c using the side conveyance belts 32b and 32c on both sides, so that the medium- or large-sized photosensitive material is integrated. It can be reliably transported without breaking the posture. The widths and the number of the conveyor belts 32a to 32c are not limited to those shown in the drawings, and may be appropriately changed according to the size of the photosensitive material 20a to be used.
[0017]
FIG. 4 shows a schematic configuration of the sorter unit 28. In FIG. 4, only the central conveyor belt 32a is shown as a representative of the conveyor belts 32a to 32c, but the other side conveyor belts 32b and 32c are configured in the same manner as the central conveyor belt 32a. The conveyor belt 32 a is stretched around pulleys 38 and 39 provided at both ends of the frame 31. The pulleys 38 and 39 are formed with a thicker crown at the center than at both ends, thereby preventing the conveyor belt 32a from coming off. The pulley 38 on the receiving position side below the discharge port 27a is driven, and the pulley 39 on the take-out side is driven. A pulse motor 41 is connected to the drive pulley 39 via a speed reduction mechanism 40. The pulse motor 41 is connected to the controller 43 via a driver 42.
[0018]
Although the distance (discharge port height) La in the vertical direction from the discharge roller pair 29 to the conveyance belt 32a is set to 55 mm, it may be appropriately changed within a range of 25 to 60 mm. This distance La is preferably 40 to 56 mm, and more preferably 50 to 55 mm. If the distance La is less than 25 mm, sheet stacking failure occurs, and if the distance La exceeds 60 mm, sheet dropping failure occurs.
[0019]
The controller 43 controls the rotation of the motor 41 based on paper size information and sort information 44 from a printer-side controller (not shown), and accumulates the photosensitive material 20a from the discharge port 27a in one batch for each order. In the present embodiment, as the accumulation mode, there are two modes of a partial stacking mode as shown in FIG. 3 and a flat stacking mode as shown in FIG.
[0020]
As shown in FIG. 5, in the flat stacking mode, one order of the photosensitive material 20a is integrated as a unit on each of the conveyor belts 32a to 32c, and the integrated photosensitive materials 45a, 45b, 45c,. Separated apart. Further, in the partial stacking mode, as shown in FIG. 3, the ends of adjacent ones of the stacked photosensitive materials 45a, 45b, 45c,. In this partial stacking mode, the stacking space is effectively used and the stacking efficiency is increased by the amount of both ends of the stacked photosensitive materials 45a, 45b, 45c,. For this reason, as shown in FIG. 4, the controller 43 stores a table 43b representing the relationship between the print size and the belt feed amount at the time of accumulation in the memory 43a for each mode. After the integration for one order, the motor 41 is rotationally controlled based on the belt movement amount corresponding to each mode, the previous integrated photosensitive material 45a is stopped at the position corresponding to each mode, and the next new By collecting the photosensitive material, each order is sorted by flat stacking or stacking.
[0021]
As shown in FIGS. 4 and 6, edge aligning flappers 33a and 33b are arranged at the dropping position of the photosensitive material 20a. These flappers 33a and 33b are disposed between the central conveyance belt 32a and the side conveyance belts 32b and 32c. These flappers 33a and 33b are rotatably attached to the shaft 38a of the driven pulley 38. As shown in FIG. 7, the flapper 33a and 33b descends from the receiving position as shown in FIG. And can be rotated between a transfer position for transferring the photosensitive material 20a after being accumulated on the conveyor belt 32a. The flappers 33a and 33b are displaced between a receiving position and a delivery position by a flapper position switching mechanism 52.
[0022]
As shown in FIG. 4, the flapper position switching mechanism 52 includes an eccentric cam 53, a cam shaft 54 to which the eccentric cam 53 is fixed, a motor 56 that rotates the cam shaft 54 via a reduction gear train 55, a flapper The position detection sensor 57 (see FIG. 6) is used. The motor 56 is connected to the controller 43 via a driver 56a. The controller 43 rotates the motor 56 to intermittently rotate the cam shaft 54 by 180 degrees, and alternately switches the flappers 33a and 33b between the receiving position and the delivery position.
[0023]
As shown in FIG. 6, the flapper position detection sensor 57 includes a sensor plate 58 fixed to the cam shaft 54 and a photo interrupter 59 that is turned on / off by the sensor plate 58. The flapper position detection sensor 57 is not limited to the illustrated example, and any other detection type sensors may be used as long as the positions of the flappers 33a and 33b can be detected.
[0024]
As shown in FIGS. 2 to 4, the edge alignment guide members 34 a and 34 b are attached in a standing state to the receiving end 31 a of the frame 31. By receiving the rear end portion of the photosensitive material 20 a, these edge aligning guide members 34 a and 34 b Align the rear edge of the. In particular, when the edge alignment flappers 33a and 33b are in the receiving position, the rear end portion of the photosensitive material 20a abuts against the edge alignment guide members 34a and 34b due to the inclination thereof, so that the edges can be securely aligned. Can be aligned.
[0025]
As shown in FIG. 2, a stopper 35 is detachably attached to an end portion of the frame 31 on the exit side of the photosensitive material by an attachment screw 37. Even when the stopper 35 is accumulated on the conveyor belts 32a to 32c in excess of the stock capacity, the integrated photosensitive material 45a, 45b,... Is prevented from dropping off from the conveyor belts 32a to 32c. The materials 45a, 45b,. The stopper 35 may be attached by fitting means, locking means, or the like, in addition to using the attachment screw 37.
[0026]
As shown in FIG. 4, an integrated photosensitive material sensor 67 using a photo interrupter is attached to the stopper 35. The output of the integrated photosensitive material sensor 67 is sent to the controller 43. Based on the output of the integrated photosensitive material sensor 67, the controller 43 issues a full alarm to notify the operator. In response to this alarm, the operator takes out the integrated photosensitive materials 45a, 45b,... From the sorter unit 28 and stores them in a delivery bag such as a DP bag.
[0027]
The stopper 35 is detachably attached to the frame 31, and is removed. Instead, a stacking box is attached at the dropping position, or another sorter or stacking conveyor is connected so as to continue to the sorter unit. May be. In this case, since the accumulated photosensitive material for each order is sent to an accumulation box, another sorter, an accumulation conveyor, etc., the accumulation capability can be increased. In addition, the accumulated photosensitive material may accumulate a lot of orders, which may result in poor visual recognition of clear sorting parts due to gaps or partial overlap, but the back side of the photosensitive material has an order number, frame number, etc. Is often recorded, and by searching for the partition of each order based on these numbers, it is possible to sort each order. In addition, when an index print in which each frame in the same order is displayed in a list as a thumbnail image is inserted into the partition of each order, the integrated photosensitive material in which each order is accumulated based on this index print. Can be sorted again for each order.
[0028]
Next, the operation of this embodiment will be described. In the present embodiment, a flat stacking mode and a partial stacking mode can be selected. The flat stacking mode is selected in the low season when the amount of print processing is small. In this flat stacking mode, as shown in FIG. 5, the integrated photosensitive material for one order is sorted at a predetermined gap Ga (for example, 15 mm) for each sorting. In addition, when the print processing amount is large, the partial stacking mode is selected. In this partial stacking mode, as shown in FIG. 3, one order of integrated photosensitive material is stacked and stacked by a predetermined overlapping length Lb (for example, 20 mm). The interval Ga and the length Lb may be changed as appropriate.
[0029]
9 and 10 sequentially show the sorting state in the partial stacking mode. First, the size of the photosensitive material 20a to be received is specified based on the print size information, and it is determined whether or not to use the flappers 33a and 33b. When the length Lp of the photosensitive material 20a is in the relationship of Lf ≧ (Lp / 2) with respect to the length Lf of the flappers 33a and 33b, the photosensitive material 20a does not fall off from the flappers 33a and 33b. 33a and 33b are used. In the case of Lf <(Lp / 2), the center of gravity of the photosensitive material 20a is at a position away from the tips of the flappers 33a and 33b, and thus falls down from the flappers 33a and 33b. In this case, the flappers 33a and 33b are not used. Even when the width of the photosensitive material 20a is larger than the width Wf (see FIG. 6) between both side edges of the flappers 33a and 33b, and the photosensitive material 20a is not stable on the flappers 33a and 33b, the flappers 33a and 33b. Is not used.
[0030]
When the sizes of the flappers 33a and 33b are usable, as shown in (A), the flapper 33a (only the flapper 33a is representatively shown in the reception standby state), but the flapper 33b also operates in synchronization with the flapper 33a. ) Becomes a receiving position standing up diagonally, and the photosensitive material 20a is received at this position. When one order of photosensitive material 20 a is discharged, a sort signal is sent to the controller 43.
[0031]
Based on the sort signal, the controller 43 receives the last photosensitive material 20a of the same order by the flapper 33a, and then lowers the flapper 33a to switch to the delivery position as shown in (C). At the delivery position in the horizontal state, the photosensitive material 20a for one order on the flappers 33a and 33b is placed on the transport belts 32a to 32c. After switching to this delivery position, the motor 41 rotates and the conveying belt is fed by a predetermined feed amount as shown in FIG. By changing the feed amount, the photosensitive material 20a is grouped by one for each order in either the partial stacking mode as shown in FIG. 3 or the flat stacking mode as shown in FIG. The
[0032]
Further, as shown in FIG. 9C, the moving speed Vb of the integrated photosensitive material 45a by the transport belt 32b is made the same in synchronism with the discharge speed Va of the first photosensitive material 20a for the next order. The photosensitive material 20a of the next order is discharged at a position where it can be surely overlapped. Hereinafter, by repeating FIG. 9C and FIGS. 10D to 10H, a part of the integrated photosensitive material for the next order (overlapping length) with respect to the integrated photosensitive material for the previous order. Lb) is superimposed. In the acceleration / deceleration region until the moving speed Vb is reached, an acceleration that does not cause collapse of the integrated photosensitive material is employed. Even if the discharge speed Va and the belt moving speed Vb are not synchronized, the same result as described above can be obtained by devising the control method, for example, by setting Vb> Va and delaying the sorting timing.
[0033]
The total length L of the conveyor belt is 635 mm, and the discharge direction of 89 mm x 127 mm photo prints is changed to make a longitudinal feed (width 89 mm x feed amount 127 mm) and a lateral feed (width 127 mm x feed amount 89 mm). The accumulation results with the stacking mode were compared. In the flat stacking mode, the interval Ga between the integrated photosensitive materials is 15 mm, and in the partial stacking mode, the overlapping length Lb of each integrated photosensitive material is 20 mm. In the vertical stacking mode, the number of stacks is 4, whereas in the partial stacking mode, the stacking number is 5, and stacking can be increased by one. In addition, the number of accumulations is 6 in the horizontal feed flat stacking mode, whereas the number of accumulations is 8 in the partial stacking mode.
[0034]
Depending on the size of the photosensitive material 20a, the intermittent feed length for sorting by the transport belt may be appropriately changed. In this case, the photosensitive material 20a is stacked and accumulated by making the intermittent feed length longer than the length of the photosensitive material 20a in the transport direction, and partially stacked and accumulated by shortening. For example, in the case of the flat stack mode, the photosensitive material 20a having a short length of less than 89 mm has a feed length of (photosensitive material length + 25 mm), and the photosensitive material 20a having a length of 89 mm or more and less than 102 mm (photosensitive material length + 18 mm). When the distance is 103 mm or more and 305 mm or less, the feed length is (photosensitive material length + 15 mm). In the case of the partial stacking mode, the photosensitive material with a length of 127 mm or more and less than 146 mm (photosensitive material length—20 mm) and the photosensitive material with a length of 146 mm or more but less than 158 mm have a feed length of (photosensitive material length—40 mm). . In addition, the photosensitive material of other lengths is set to a flat stacking mode without using the partial stacking mode, and when it is 82.5 mm or more and less than 102 mm (photosensitive material length + 25 mm), it is 102 mm or more and less than 127 mm or 158 mm or more and 306 mm or less. The feed length is (photosensitive material length + 15 mm). Note that this is an example, and the combinations and numerical values thereof may be changed as appropriate.
[0035]
In the case of a medium-size or large-size photosensitive material that does not use the flappers 33a and 33b, the flappers 33a and 33b are held at the delivery position as shown in FIG. Thus, it is sorted for each order. Further, the flappers 33a and 33b are not essential components in the present invention and may be omitted. However, the flappers 33a and 33b are preferably installed from the viewpoint of surely aligning the edges of the photosensitive material.
[0036]
In the above embodiment, the accumulation of photosensitive materials having the same size has been described as an example. However, the present embodiment may be applied to a case where various sizes are mixed. Further, in the case of stacking without using the flappers 33a and 33b, tip alignment may be performed. In this case, the receiving position of each integrated photosensitive material is changed by rotationally controlling the motor of the discharge roller pair, the conveyor belt 32a, and the like so that the leading ends of the photosensitive materials are aligned at the time of integration. A specific configuration of this tip alignment is described in detail in, for example, Japanese Patent Laid-Open No. 10-161292.
[0037]
In the above embodiment, the conveying direction of the conveying belt is made to coincide with the discharging direction of the photosensitive material 20a. However, as shown in FIG. 11, the conveying direction (arrow A1) of the conveying belt 70 is set as shown in FIG. You may implement this invention to what was set as the direction orthogonal to the discharge direction (arrow A2) of 20a. 11A is a plan view, and FIG. 11B is a front view. In this case as well, the integrated photosensitive materials 71a to 71e can be partially stacked on the transport belt 70 in the stacking mode. In addition, the same code | symbol is attached | subjected to the same member as the said embodiment, and description is abbreviate | omitted.
[0038]
In the above embodiment, the photographic print as a sheet in the printer processor has been described as an example. However, the present invention may be implemented in a sheet sorting apparatus in another recording apparatus or copying apparatus. Further, instead of sorting the sheets for each order, the sheets may be sorted under various conditions.
[0039]
【The invention's effect】
According to the present invention, the sheets are stacked on the conveying member in units of a plurality of sheets, and one end of these stacked sheets is arranged so as to overlap the other end of the next stacked sheet. Therefore, the space can be saved and the integration efficiency can be increased accordingly. In addition, since each stacking sheet is stacked so as to cover the previous stacking sheet, even if the stacking sheet is stopped by a stopper or the like without being taken out of the conveying member, Accumulated prints are collected. Therefore, inconveniences such as the print order being disordered and collecting will not occur.
