[0001]
[Industrial applications]
The present invention relates to a sheet-like member conveying device, and more particularly to a sheet-like member conveying device that is used in a printer processor or the like and is capable of stacking and conveying a plurality of cut prints and the like.
[0002]
[Prior art]
At a photo lab or the like, photographs are printed by a printer processor.
[0003]
The printer processor includes a printer unit for printing and a processor unit for developing, fixing, washing, drying, etc.Print paper is cut to a predetermined size by a cutter unit provided after the drying unit of the processor unit. Is done.
[0004]
The cut prints need to be accumulated for each order, for example, in order to make a break for each order (one negative film).
[0005]
For this reason, the printer processor is provided with a transport device that collects and transports the cut prints for each order.
[0006]
As shown in FIG. 13, such a transfer device is provided between a side plate 32 and a side plate 34 in a tray 46 attached to a chain (not shown) driven by a motor or the like for one order (for example, one film). There is a transport device 11 configured to accumulate the prints and transport the prints downward.
[0007]
In the transport device 11, the receiving tray 46 is arranged on the side of the cutter unit 18, and the cut prints 20A discharged from the cutter unit 18 are dropped on the receiving tray 46 and collected.
[0008]
[Problems to be solved by the invention]
However, in recent years, a long print such as a panoramic size may be processed by a printer processor.
[0009]
However, as shown in FIG. 13, when the next panorama-sized cut print 20A ′ is discharged from the cutter unit 18 on the already-collected panorama-size cut print 20A, the next discharge that is being discharged is performed. It is conceivable that the leading end of the cut print 20A 'comes into contact with the upper surface (photosensitive surface) of the already-collected cut print 20A, and the already-collected top cut print 20A is shifted to the side plate 34 side. Can be
[0010]
In this state, when the cut prints 20A and 20A ′ that have been collected are pushed out by the print push plate 94, the front end of the cut print 20A shifted to the side plate 34 comes into contact with the side plate 34 as shown in FIG. If the tray 46 is moved as it is, the edge of the cut print 20A may be rubbed against the side plate 34 and damaged.
[0011]
The present invention has been made in consideration of the above-described circumstances, and has as its object to provide a sheet-like member conveying apparatus that can convey a sheet-like member without damaging the sheet-like member.
[0012]
[Means for Solving the Problems]
The invention according to claim 1 is a sheet-like member conveying device provided on a sheet-like member discharge side of a discharge unit for discharging a sheet-like member, wherein the sheet-like member is disposed below the discharge unit and discharged from the discharge unit. The sheet-like memberIs placedPlacement section and placement section described aboveAnd the sheet-like member discharged from the discharge unit is placed on the downstream side of the discharge direction of the sheet-like member by the discharge unit.With a sheet-shaped member receiving part, The sheet-like member is placedThe receiving unit, wherein the sheet-shaped member receiving unit isFrom the position on the downstream side in the discharge direction with respect toTransport means for transporting to a predetermined position; andTashiOf the discharge member side of the sheet-shaped memberRear endIn contact with,Sheet-like memberLocated on the downstream side in the discharge direction with respect to the placing sectionExtruding means for extruding the sheet-shaped member receiving portion,When discharging sheet-like members from the discharge sectionThe sheet-shaped member receiving portionHeld near the downstream end in the discharge directionIs placed on the sheet-shaped member receiving portion,TashiSheet-like memberDownstream of the predetermined position in the discharge direction by the sheet-like member discharged next from the discharge portion.So as not to slipNishiSheet-like memberTipA stopper for holding the stopper, the stopper being connected to the pushing means, andButA connection member for retracting the stopper from the sheet-shaped member receiving portion in conjunction with pushing out the sheet-shaped member.
[0013]
According to a second aspect of the present invention, there is provided the sheet-like member conveying device according to the first aspect,The retracting amount by which the connecting member retracts the stopper along the direction in which the sheet-like member is pushed out by the pushing-out means is made larger than the amount by which the pushing-out means pushes out the sheet-like member.It is characterized by:
[0014]
[Action]
The sheet-like member conveying device according to the first aspect can be used, for example, in a printer processor. The photosensitive material (sheet-like member) that has been subjected to the printing, developing and drying processes by the printer processor is cut into a predetermined length by a cutter unit and discharged from a discharge unit.
[0015]
The discharged sheet-like member falls to the side of the discharge unit and is temporarily mounted on the mounting unit. When the sheet-like member is once placed on the placing section,Holds the sheet-shaped member receiving part at the position downstream of the discharge direction in advanceBy doing so, a part of the sheet-shaped member can be supported by the sheet-shaped member receiving portion.
[0016]
Here, when the long sheet-shaped member is placed, and the long sheet-shaped member is further discharged from the side, the sheet-shaped member placed on the top is being discharged. There is a case where the sheet-like member is pushed in the discharge direction near the leading end of the sheet-like member. At this time, the stopper presses the end of the sheet-like member so as not to shift the sheet-like member from the predetermined position in the discharge direction.
[0017]
After a predetermined number (for example, one order) of sheet-like members are stacked, the stacked sheet-like members are extruded by a predetermined size by an extruding means and are all moved into the sheet-like member receiving portion.
At this time, the connecting member connecting the stopper and the pushing means retracts the stopper from the sheet-like member receiving portion in conjunction with the pushing means pushing out the sheet-like member. Thus, the sheet-like member can be pushed deeper into the sheet-like member receiving portion by the pushing means, so that the inside of the sheet-like member receiving portion can be effectively used.
[0018]
Here, the position at which the stopper presses the end of the sheet-shaped member is closer to the discharge portion than the extrusion dimension by which the pushing means pushes the sheet-shaped member from the end of the sheet-shaped member receiving portion on the sheet-shaped member discharge direction side. I do. Thereby, when the pushing means pushes out the sheet-like member, the sheet-like member does not protrude from the end of the sheet-like member receiving portion on the sheet-like member discharging direction side. Even if a wall or the like is adjacent in the discharge direction of the member, the sheet member can be prevented from contacting the wall or the like.
[0019]
Then, the sheet-like member is operated by operating the conveying means.Was placedPlace the sheet-shaped member receiving partRemove from the position downstream in the discharge directionPredeterminedofCan be moved to the position.
[0020]
Further, in the sheet-like member conveying device according to claim 2,The retracting amount by which the connecting member retracts the stopper along the direction in which the sheet-like member is pushed out by the pushing-out means is larger than the amount by which the pushing-out means pushes out the sheet-like member. Thereby, when the sheet-like member is pushed out to the sheet-like member receiving portion by the pushing means, a gap is formed between the sheet-like member and the stopper retracted from the sheet-like member receiving portion by the connecting member, and the sheet-like member is formed. The load from the stopper does not act on.

[0069]
Next, the operation of the sorting and conveying apparatus 10 will be described based on the flowchart of FIG.
[0070]
In step 200, the long print paper 20 after the drying process is fed by the rollers 22 of the cutter unit 18.
[0071]
In step 202, a cut hole is detected by the cut hole sensor 26, and in step 204, a predetermined amount of the long print paper 20 is fed.
[0072]
In step 206, the cutter 28 operates to cut the print paper 20.
[0073]
In step 208, the cut print 20 </ b> A is fed by a predetermined amount by the discharge roller 30, and falls on the placing plate 84 and the receiving tray 46.
[0074]
Before the cut print 20A falls, the print pushing plate 94 is located on the cutter unit 18 side (the position shown by the solid line in FIG. 9), and the receiving tray 46 is slightly lower than the placing plate 84. It is located in.
[0075]
Since the mounting plate 84 and the receiving tray 46 are lowered on the cutter unit 18 side, the cut print 20A on the mounting plate 84 and the receiving tray 46 slides to the cutter unit 18 side, and the rear end (the end portion on the cutter unit 18 side) ) Are aligned by contacting the print extruding plate 94.
[0076]
In step 210, it is determined whether or not a sort hole (not shown) of the print paper 20 has been detected. If no sort hole has been detected, the process returns to step 200, and the above-described processing is repeated. The prints 20A are sequentially stacked on the receiving tray 46 and the placing plate 84 with their rear ends aligned.
[0077]
When a sort hole of the print paper 20 is detected in step 210, the process proceeds to step 212, where a predetermined amount of the long print paper 20 is fed.
[0078]
In step 214, the cutter 28 is operated, and the last part of the order of the print paper 20 is cut.
[0079]
In step 216, the discharge roller 30 rotates by a fixed amount, and the cut print 20A that is the final in the order is discharged and falls. As described above, prints of one order are stacked on the tray 46 and the mounting plate 84.
[0080]
In the sorting / conveying device 10, the cut prints 20A discharged from the cutter unit 18 are accumulated on the mounting plate 84 and the tray 46, and the long panoramic size cut prints 20A are discharged from the cutter unit 18. In this case, as described in the related art, the cut prints 20A that have already been collected may be pushed by the next cut print 20A that is being discharged. When stacking the cut prints 20A on the cutout 46, the stopper plate 134 has entered the relief groove 136 of the tray 46, so that the leading end of the next cut print 20A is already stacked on the cut prints 20A that have already been stacked. Even if they come into contact with each other, the cut prints 20A that have already been collected are not displaced because they hit the stopper plate 134, and the cut prints 20A are aligned. It is integrated with.
[0081]
When the cut prints 20A are collected, as shown in FIG. 9, the bearing 112 of the swing arm 106 is located at the shortest distance from the rotation center in the outer peripheral surface of the cam 82.
[0082]
If the cut print 20A of the last order is ejected and dropped in step 216, the process proceeds to step 230.
[0083]
In step 230, the geared motor 72 is driven, and the cam 82 and the worm wheel 66 rotate.
[0084]
The pan 46 on which the cut prints 20A are accumulated is moved downward by the rotation of the worm wheel 66.
[0085]
Also, while the cam 82 rotates to 110 degrees, the bearing 112 of the swing arm 106 is pushed up by the outer peripheral surface of the cam 82, and the swing arm 106 is moved in the direction opposite to the clockwise direction in FIG. (The direction opposite to the H direction). By the rotation of the swing arm 106, the moving member 90 approaches the side plate 32 side, and pushes the cut prints 20A of one order in which the print push-out plates 94 are integrated into the tray 46 side. At the same time, the slide shaft 88 slides in the pushing direction of the cut print 20A, and the swing arm 106 is pushed by the bearing 130 attached to the tip of the slide shaft 88, so that the swing arm 106 is rotated in the direction opposite to the clockwise direction in FIG. The stopper plate 134 is retracted from the escape groove 136 of the tray 46. When the pushing operation by the print pushing plate 94 is completed (when the cam 82 is rotated by 110 degrees), the end of the cut print 20A on the side plate 34 side is located at a position away from the side plate 34 by a predetermined distance. Therefore, the end of the cut print 20A does not contact the side plate 34 when the tray 46 is moved.
[0086]
When the pan support 44 and the pan 46 are located on the front side of the printer processor 12 and receive the cut print 20A, the weight of the pan support 44, the pan 46 and the cut print 20A causes the roller 58 to move the running surface 60A. , And the roller 62 is pressed against the running surface 60B, so that the tray 46 is maintained at a right angle to the straight portion of the endless chain 42 and does not tilt.
[0087]
Next, while the cam 82 rotates from 110 degrees to about 195 degrees, the bearing 112 of the swing arm 106 is not displaced by the cam 82 (from 110 degrees to about 195 degrees, the bearing 112 extends from the center of rotation to the outer surface of the cam). , The print extruding plate 94 is stopped in a state where it slightly enters the inside of the side plate 32.
[0088]
Next, while the cam 82 rotates from approximately 195 degrees to 345 degrees, the distance from the center of rotation to the outer surface of the cam decreases, so that the swing arm 106 rotates clockwise (in the direction of arrow H) and prints out. The plate 94 comes closest to the cutter unit 18 side. In this embodiment, when the uppermost cut prints 20 </ b> A that have been collected are lower than the mounting plate 84, the print pushing plate 94 starts to return to the cutter unit 18 side.
[0089]
Thereafter, while the cam 82 rotates from 345 degrees to 360 degrees (one rotation is completed), the bearing 112 of the swing arm 106 is not displaced by the cam 82 (because the distance from the center of rotation to the outer surface of the cam is constant). The print pushing plate 94 does not move while being positioned closest to the cutter unit 18.
[0090]
In step 232, the slit of the slit disk 64 is detected by the optical sensor 68, and the geared motor 72 stops. The rotation of the geared motor 72 stops when the cam 82 rotates 360 degrees, that is, once. At this time, the next empty tray 46 is stopped at a predetermined position beside the mounting plate 84. Then, when the next slit is detected by the optical sensor 68 (in other words, it indicates that the movement of the tray 46 for one order is completed), the process returns to step 200, and the cutting of the print paper 20 of the next order is performed by the cutter. The operation starts at the section 18.
[0091]
Thereafter, as long as there is the print paper 20 to be dried, the above-described processing is repeated, and the tray 46 on which the cut prints 20A for each order are stacked is sequentially conveyed downward.
[0092]
When the pan support 44 and the pan 46 are conveyed downward and the outer link 52 of the pan endless chain 42 that supports them rests on the sprocket 40 of the shaft 38, the pan support 44 is no longer guided by the guide rail 60, The outer link 52 moves while engaging with the sprocket 40. As a result, the tray support 44 and the tray 46 tilt, and the cut print 20A of one order slides out to the upper front side of the processor unit 16.
[0093]
By using the cam 82 as in this embodiment, it is possible to easily and freely control the extrusion time and the return time of the print extruding plate 94.
[0094]
In addition, it is preferable that the ejection time of the cut print 20A by the print pushing plate 94 be set to a short time because the receiving tray 46 has already started to move.
[0095]
In addition, the longer the print pushing plate 94 is stopped after pushing the cut print 20A, the better the stability of the accumulated cut prints 20A. The reason for this is that if the printed push-out plate 94 is not returned to the cutter section 18 when the uppermost cut prints 20A stacked as described above become lower than the mounting plate 84, the upper cut This is because the completed print 20A may be shifted toward the mounting plate 84 at the same time when the print pushing plate 94 returns.
[0096]
The return time of the print push plate 94 is preferably short in preparation for receiving the cut print 20A of the next order.
[0097]
In the present embodiment, since the worm wheel 66 is meshed with the worm gear 80, even if the cut prints 20A are accumulated in the tray 46 and the load becomes uneven, the tray 46 does not move accidentally.
[0098]
In the present embodiment, the inclination of the tray support 44 and the tray 46 is prevented by sandwiching the guide rail 60 between the roller 58 and the roller 62. However, the present invention is not limited to this. It can be changed to a sliding member having a low friction coefficient such as Teflon, nylon, or the like.
[0099]
In the present invention, an endless belt may be used instead of the endless chain 42. In the present embodiment, the print pushing plate 94 and the stopper plate 134 are simultaneously moved by one motor. However, the print pushing plate 94 and the stopper plate 134 are independently driven by using separate motors. May be. In this case, the print pushing plate 94 and the stopper plate 134 may be moved at the same time. For example, the print pushing plate 94 may be moved after the stopper plate 134 is retracted.
[0100]
Further, in this embodiment, an example in which the sheet-like member conveying device of the present invention is used for a printer processor is shown, but the sheet-like member conveying device of the present invention can be used for devices other than the printer processor.
[0101]
【The invention's effect】
As described above, the sheet-like member conveying device of the present invention can prevent the stopper from shifting the sheet-like member in the discharge direction from a predetermined position, and can convey the mounted sheet-like member in the best condition. It has an excellent effect.
[0102]
In addition, by retracting the stopper when the pushing means pushes out the sheet-like member, the inside of the sheet-like member receiving portion can be effectively used.
