[0001]
BACKGROUND OF THE INVENTION
The present invention provides a conveying means having a pair of peripheral surfaces for moving a photographic photographic paper while being pressed from both sides of the photographic photographic paper, and conveying the photographic photographic paper discharged from the conveying means to the conveying means. The present invention relates to a transport mechanism for photographic printing paper provided with guide means for guiding to a downstream transport path intersecting an upstream transport path positioned on the upstream side.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, examples of a transport mechanism for photographic printing paper that fulfills the above-described purpose include a transport mechanism provided on the downstream side of an exposure section of a photographic printer processor as illustrated in FIG. In this transport mechanism, the exposed photographic paper 1 transported vertically upward from the exposure section is printed in order to guide it to the next horizontal transport path toward the development processing section 13 ′ located beside the exposure section. A turn portion is provided to change the paper traveling direction by about 90 °. The turn section includes one turn roller 70 that is rotated around a horizontal axis by a driving unit such as a motor, a first pressure roller 72 that presses the photographic paper 1 against the side surface of the turn roller 70 from the horizontal direction, A second pressure roller 74 is provided on the downstream side of the first pressure roller 72 and presses the photographic paper 1 against the upper surface of the turn roller 70 from above. Further, the turn portion includes photographic paper 1 conveyed by the plurality of rollers 70, 72, 74 and guide members 76, 78 facing the emulsion surface and the non-emulsion surface of the photographic paper 1 from both sides. The guide members 76, 78 include extensions 76 a, 78 a that extend further downstream from the pressure-bonding surface between the turn roller 70 and the second pressure roller 74, and the extensions 76 a, 78 a It extends in parallel with a tangent line extending horizontally from between the second pressure roller 74. However, since a sufficient interval is formed between the extension portions 76a and 78a, the photographic paper 1 during normal use (that is, transported by the roller pair 30 'and 30' disposed in the development processing section 13 ') is used. It can be expected that the photographic paper 1) in the state where the printing has been started is conveyed without contacting any of the upper and lower extensions 76a and 78a. If the upper and lower extensions 76a and 78a are not provided, the operation of transferring the leading edge of the photographic paper 1 to the roller pair 30 'of the developing unit 13' cannot be performed smoothly.
[0003]
[Problems to be solved by the invention]
However, in the transport mechanism for photographic printing paper having the above-described configuration, the operation of transferring the leading edge of the printing paper to the roller pair on the developing unit side, or the transport speed of the turn roller and the transport speed of the roller pair on the developing unit side. If the discrepancy occurs, the emulsion surface at the tip of the photographic paper may come into contact with the guide member (particularly, the lower guide plate) and be damaged.
[0004]
Therefore, in view of the above-mentioned drawbacks of the transport mechanism for photographic photographic paper according to the prior art exemplified above, the object of the present invention is to perform the operation of transferring the leading edge of the photographic paper to the roller pair on the developing unit side, or Photographic paper with less risk of damage due to contact of the emulsion surface at the leading edge of the photographic paper with the guide member even when the conveyance speed of the turn roller and the conveyance speed of the roller pair on the developing unit side do not match. It is in providing the conveyance mechanism for.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, a transport mechanism for photographic printing paper according to the present invention has the characteristic structure described in claims 1 to 6 of the claims.
Incidentally, a transport mechanism for photographic paper according to claim 1 of the present invention is:
In order for the guide means to change the path of the photographic paper discharged from the transport means to the downstream transport path based on contact with the non-emulsion surface of the photographic paper, the transport means And a guide surface intersecting with the photographic printing paper feed direction.
[0006]
Due to such a characteristic configuration, in the photographic paper transport mechanism according to claim 1 of the present invention, the photographic paper discharged from the transport means is guided to the guide means. Since the surface contacts with the non-emulsion surface of the photographic printing paper, the path of the photographic printing paper is changed to the transport path without the guide surface contacting the emulsion surface. Therefore, the emulsion surface of the photographic printing paper is less likely to be damaged when the course is changed.
[0007]
Further, the photographic printing paper feed direction of the transport means is less than a predetermined angle formed by both the downstream transport path and the upstream transport path and the downstream transport path with respect to the upstream transport path. It can be configured to form an inclination angle.
With this configuration, when the photographic printing paper is transferred from the downstream conveyance path to the pair of peripheral surfaces, the photographic printing paper is changed in course at an inclination angle that is less than the predetermined angle, and then the downstream of the pair of peripheral surfaces from the pair of peripheral surfaces. When changing to the side conveyance path, the course is changed again at an inclination angle lower than the predetermined angle, and the course change of the predetermined angle is achieved in two stages. Therefore, as shown in the example of FIG. Compared to a configuration that achieves a change of course at a predetermined angle at a time, the degree of curved deformation corrected on the photographic paper is substantially reduced, and the photographic paper is more damaged when changing the course. It is hard to receive.
[0008]
More specifically, the predetermined angle is 90 °, and the guide surface of the guide means is 90 ° with a tangent line formed between the pair of peripheral surfaces of the transport means and photographic printing paper. It can comprise so that the inclination | tilt angle below may be made.
[0009]
More specifically, the inclination angle may be in the range of 15 ° and 45 °.
In general, photographic printing paper is supplied in the form of a roll with the emulsion side facing outward, so it tends to curl into a curved shape that wraps the base surface side (non-emulsion surface) inside. If configured, the photographic printing paper discharged from the pair of peripheral surfaces is discharged so that the base surface side (non-emulsion surface) is pressed against the guide surface, while still being applied to the photographic printing paper. The course is changed to the downstream conveyance path without applying an excessive deformation force.
[0010]
The photographic printing paper feed direction of the conveying means is a first and second roller pair having mutually parallel shaft cores, and a first endless belt wound around each peripheral surface of the first roller pair. And a second endless belt wound around each peripheral surface of the second roller pair so as to press the photographic printing paper against the outer peripheral surface of the first endless belt.
[0011]
According to this structure, the photographic printing paper is conveyed based on sufficient surface contact between the two endless belts, so that the combination of the roller pairs and the roller pairs are extended. Compared to a transport mechanism composed only of guide members, problems such as a meandering tendency associated with a change of course and damage to the photographic printing paper, particularly the emulsion surface side, due to friction with the guide members are less likely to occur.
[0012]
Further, a fifth roller that is rotatable around an axis arranged in a triangular shape in cooperation with both axes of the first roller pair is provided upstream of the first roller pair. The first endless belt is wound around three rollers including the first roller pair and the fifth roller at the same time, and from the peripheral surface of the fifth roller to the peripheral surface of the first roller pair. The upstream portion of the first endless belt extending toward the upstream extends along the upstream conveyance path, and the second endless belt can press the photographic printing paper against the upstream portion of the first endless belt. It can be set as the structure said.
[0013]
If constituted in this way, the first endless belt extending from the peripheral surface of the fifth roller toward the peripheral surface of the upstream roller of the first roller pair corresponds to the second endless belt. The first endless belt is gently curved at the curvature portion of the first endless belt that is transported along the upstream transport path formed in cooperation with the portion to be wound and then wound around the upstream surface of the first roller pair. While the route is changed (the route is changed by less than 90 °), the first and second endless belts are consistently sandwiched between the first and second endless belts in the vicinity of the first roller pair. In the worn state, the sheet is transported without a means such as a guide member for helping to change the course. Therefore, there is little possibility that the emulsion surface of the photographic printing paper is damaged by friction with the stationary guide member.
[0014]
Other features and advantages of the present invention will become apparent from the following description of embodiments using the drawings.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
An example of an embodiment of the present invention will be described based on the drawings.
1 and 2 show a printer processor 100 as a photographic processing apparatus to which a photographic printing paper transport mechanism according to the present invention is applied.
(Overall structure of printer processor)
The printer processor 100 includes a printing exposure unit A and a development processing unit B. Among these, the printing exposure unit A mainly includes a pair of paper magazines 3A and 3B that store the photographic paper P1 or P2 wound in a roll shape, a transport device 6 mainly composed of a transport belt, an exposure light source 9, A known structure including a mirror tunnel 10, a film mask 11 for holding a photographic film F, and a lens unit 12 is provided. On the other hand, the development processing section B includes a development processing tank section 13 having a plurality of tanks 13a for storing the development processing liquid, a drying processing section 14 for drying the photographic paper after the development processing. Further, a control device (not shown) for controlling the operation of each part belonging to the printing exposure unit A and the development processing unit B according to an instruction input from a console not shown in particular and a preset program. Is provided.
[0016]
The photographic paper P1 or P2 drawn out from one of the paper magazines 3A and 3B is sent to the cutter unit 8 by the transport device 6, where it is cut into an appropriate rectangular dimension, and then a part of the transport device 6 (In FIG. 1, the photographic paper 1 is shown stationary on the exposure table 7 by the suction mechanism provided on the exposure table 7). Here, the light emitted from the light source 9 passes through the photographic film F on the film mask 11, passes through the lens unit 12, and is irradiated onto the rectangular photographic paper on the exposure table 7 for an appropriate period of time. A printing exposure is performed. The printing paper 1 that has been subjected to printing exposure is fed toward the development tank 13 along the direction of the arrow by the latter half of the transport device 6. The latter half of the transport device 6 includes a first transport roller unit 6U having an inclined transport path and a second transport roller unit 6U ′ having a transport path extending vertically upward. Each of the first and second transport roller units 6U and 6U ′ is composed of two endless belt drive mechanisms wound around a pair of rollers spaced apart from each other, and these endless belt drive mechanisms face each other and are photographic paper. 1 is transported while being sandwiched therebetween.
[0017]
The corner portion transport mechanism 20 is disposed downstream of the second transport roller unit 6U ′, in other words, above the second transport roller unit 6U ′. The corner portion transport mechanism 20 plays a role of changing the course of the photographic paper 1 transported along the vertically extending transport path in the second transport roller unit 6U 'to the horizontally extending downstream transport path. .
As shown in FIG. 3, the corner portion transport mechanism 20 includes a first turn belt B <b> 1 (the first turn belt) wound around three rollers R <b> 1, R <b> 2, R <b> 5 that can rotate around horizontal axis cores that are parallel to each other. In order to sandwich the photographic paper 1 in cooperation with the first turn belt B1 and an example of an endless belt, three other rotations that can be rotated around horizontal axes that are also parallel to each other are provided. Conveying means composed of a second turn belt B2 (an example of a second endless belt) wound around the rollers R3, R4, R6, and the vicinity of the exits of the first turn belt B1 and the second turn belt B2 And a guide means constituted by a guide member 22 disposed in the space.
[0018]
Of the rollers R1, R2, and R5 that support the first turn belt B1, the two downstream rollers R1 and R2 constitute a first roller pair RP1. Of the two rollers R1 and R2 of the first roller pair RP1, the shaft core of the roller R2 on the downstream side is disposed above the roller R1, and therefore, an imaginary line segment that connects the two shaft cores to each other. Is inclined by about 45 ° with respect to the horizontal. However, the roller R1, which is a central driving roller that determines the degree of curved deformation applied to the photographic paper 1 when the route is changed by the corner portion transport mechanism 20, is for the purpose of reducing the burden due to the deformation to the photographic paper 1. As a result, the diameter of the first turn belt B1 wound around the two peripheral surfaces of the first roller pair RP (the common tangent line between the roller R1 and the roller R2) is larger. Is inclined by about 30 ° with respect to the horizontal. On the other hand, the portion of the first turn belt B1 extending from the peripheral surface of the roller R1 to the peripheral surface of the roller R5 (example of fifth roller) (corresponding to the common tangent of the roller R1 and the roller R5) extends vertically upward. ing. Incidentally, the first turn belt B1 is rotationally driven by a motor via a roller R2. The second turn belt B2 is driven to rotate at a peripheral speed synchronized with the first turn belt B1 in a form driven by the rotation of the first turn belt B1. The rollers R4 and R2 are set as rollers having the same outer diameter, and the rotational movement of the roller R2 is performed via a pair of pinion gears having the same number of teeth and rotating integrally with each of the rollers R4 and R2. The second turn belt B2 may be rotationally driven at a peripheral speed synchronized with the first turn belt B1 by providing an interlocking mechanism such as transmitting to the roller R4.
[0019]
Next, among the rollers R3, R4 and R6 supporting the second turn belt B2, the two rollers R3 and R4 which are the most upstream and the most downstream constitute a second roller pair RP2. The most upstream roller R3 includes a fifth roller R5 supporting the first turn belt B1, and the first and second turn belts B1, B1 sandwiched between the two rollers R3 and R5. In cooperation with B2, a tangent line extending in the vertical direction is formed. The most downstream roller R4 cooperates with the roller R2 supporting the first turn belt B1 and the first and second turn belts B1 and B2 sandwiched between the two rollers R2 and R4. It forms a tangent line that is inclined by about 30 ° with respect to the horizontal. Further, a sixth roller R6 rotatably supported between the two rollers R3 and R4 further supports the outer track of the second turn belt B2 outward. The sixth roller R6 passes through the peripheral surface on the roller R4 from the peripheral surface on the roller R3 via the contact point with the first turn belt B1 protruding to the second turn belt B2 side by the roller R1. The second turn belt B2 immediately before returning to the roller R3 again is provided so that it does not come into contact with the second turn belt B2 pushed back inward by the roller R1.
[0020]
As a result of the above configuration, the first turn belt B1 supported by the rollers R1, R2, and R5 arranged so that the shaft cores form a triangle forms the circumferential surface of the roller R5 toward the circumferential surface of the roller R1. A first linear track extending linearly and a second linear track extending linearly from the peripheral surface of the roller R1 toward the peripheral surface of the roller R2. This second linear track defines the direction in which the photographic printing paper is fed by the conveying means constituted by the first turn belt B1 and the like.
The second turn belt B2 supported by the rollers R3, R4, and R6 is also from the peripheral surface of the roller R3 toward the peripheral surface formed by the first turn belt B1 on the peripheral surface of the roller R1. A first linear track extending linearly and a second linear track extending linearly from the pseudo-formed peripheral surface toward the peripheral surface of the roller R4.
Each first linear track of the first turn belt B1 and the second turn belt B2 extends vertically, and similarly, the second linear track extends at an inclination angle of about 30 ° with respect to the horizontal.
[0021]
The guide member 22 includes a base surface side guide plate member 24 disposed above and an emulsion surface side guide plate member 26 disposed below near the exits of the first turn belt B1 and the second turn belt B2. . The base surface side guide plate member 24 is formed with a guide surface 24a facing downward and extending horizontally, and the emulsion surface side guide plate member 26 is formed with a guide surface 26a facing upward and extending horizontally. Has been. In other words, the guide surface 24a of the base surface side guide plate member 24 faces the base surface side of the photographic paper 1 being conveyed, and the guide surface 26a of the emulsion surface side guide plate member 26 is the surface of the photographic paper 1 being conveyed. Facing the emulsion side. Further, the guide surface 24a and the guide surface 26a are separated from each other by a distance exceeding the thickness of the thickest photographic paper 1, thereby forming a horizontal conveyance path.
[0022]
On the other hand, the tangent formed between the first turn belt B1 and the second turn belt B2 on the second straight track, or the tangent formed between the first turn belt B1 and the photographic paper 1 is horizontal. Since the angle is about 30 °, the horizontal conveying path formed between the base surface side guide plate member 24 and the emulsion surface side guide plate member 26 of the guide member 22 is tangential to the tangent line. An angle of about 30 ° is formed. Furthermore, since the photographic paper 1 is generally supplied in a roll shape with the emulsion surface side on the outside, it tends to curl into a curved shape in which the base surface side (non-emulsion surface) is wound inside. The leading end of the photographic paper 1 discharged from the outlets of the first turn belt B1 and the second turn belt B2 generally enters the guide member 22 in a shape that is wound upward. Therefore, the leading edge of the photographic paper 1 that is discharged from the outlets of the first and second turn belts B1 and B2 and enters the guide member 22 is, as shown in FIG. It always enters the horizontal guide surface 24a on the base surface side guide plate member 24 side, not on the side, but obliquely (with an entry angle of about 30 °). Then, as shown in FIG. 5, the photographic printing paper 1 has its bending point TP on the upstream side of the guide surface 24a based on the pushing force by the first turn belt B1 and the second turn belt B2, as shown in FIG. While being held near the end portion, the base surface side is pulled out of the guide member 22 with friction on the lower surface of the base surface side guide plate member 24, that is, the guide surface 24 a, and is then developed. It is delivered to a pair of conveying rollers 30 and 30 in the section 13.
[0023]
As a result, the photographic paper 1 discharged from the second transport roller unit 6U ′ when it is transferred from the second transport roller unit 6U ′ to the development processing unit 13 via the corner section transport mechanism 20 is first of all While both surfaces are sandwiched between the first turn belt B1 and the second turn belt B2, the course is changed by the roller R1 to a path inclined toward the developing unit 13 by about 60 °, and the first turn belt B1 and the second turn belt B After exiting B2, the sheet is conveyed to the development processing unit 13 while being pressed against the upper guide surface 24a in the guide member 22, and during this time, the emulsion surface side of the photographic paper 1 is in friction with the stationary guide member. There is no process to wake up.
In this way, the photographic paper 1 (even at its tip) is conveyed through the corner conveyance mechanism 20 without contacting the emulsion surface side guide plate member 26 at all. There is no opportunity to perform the function normally, but when handling photographic paper with unusual characteristics such as curl wrinkles that are unusual or extremely weak at the waist, the leading edge of these photographic paper is the corner section conveyance mechanism 20 and a function of preventing entry into a gap formed between the units of the development processing unit 13.
[0024]
The photographic paper 1 that has passed through the development processing tank section 13 is sent to the drying processing section 14 and appropriately dried by the drying means 14a while passing through the transport path in the same section. The downstream end of the drying processing unit 14 is provided with a large-diameter driving roller 90 and pressure rollers 90a, 90b, and 90c that are in close contact with the peripheral surface of the driving roller 90 so as to be able to roll.
Further, on the further downstream side of the driving roller 90 and the pressure rollers 90a, 90b, and 90c, there is provided a sorting mechanism 15 that sorts the dried photographic paper discharged from the drying processing unit 14 up and down. A first outlet transport device 16A that sends the photographic paper slightly upward and a second outlet transport device 16B that sends the photographic paper downward are formed on the downstream side.
Due to the processing capacity at the outlet, the small photographic paper 1 is normally discharged from the upper outlet 17A to the sorter mechanism 19 by the movable guide member 40 in the first posture, and the large photographic paper 1 is the second one. The movable guide member 40 in the posture is configured to be discharged from the lower outlet 17B to the fixed tray 42.
[0025]
[Another embodiment]
As illustrated in FIG. 6, the corner portion conveyance mechanism may be configured to convey the photographic paper 1 by a plurality of roller pairs that are rotationally driven at a synchronized peripheral speed without using an endless belt.
6 includes a first roller pair R′1, R′2 located on the most upstream side, a second roller pair R′6, R′7 located on the most downstream side, An intermediate roller group R'3, R'4, R'5 disposed between the first roller pair R'1, R'2 and the second roller pair R'6, R'7, and a plurality of these And a guide member 32 provided along the roller. The guide member 32 includes a base surface side guide plate member 34 and an emulsion surface side guide plate member 36.
[0026]
The roller R'1 of the first roller pair R'1, R'2, the roller R'3 of the intermediate roller group R'3, R'4, R'5, and the second roller pair R'6, R'7 The roller R'6 is driven to rotate at a synchronous peripheral speed by a single motor. On the other hand, the roller R′2 of the first roller pair R′1 and R′2 is urged from the horizontal direction toward the roller R′1 in order to sandwich the photographic paper 1 being conveyed. The rollers R′4 and R′5 of the intermediate roller groups R′3, R′4, and R′5 are urged from the horizontal direction and obliquely upward toward the roller R′3, respectively. The roller R′7 of the roller pair R′6 and R′7 is urged obliquely from above toward the roller R′6.
[0027]
Further, it is formed between the upstream first roller pair R′1 and R′2 and between the rollers R′3 and R′4 of the intermediate roller groups R′3, R′4 and R′5. The common tangent line extends in the vertical direction along the conveyance path extending vertically above the second conveyance roller unit 6U ′. Further, it is formed between the second pair of downstream rollers R′6 and R′7 and between the rollers R′3 and R′5 of the intermediate roller groups R′3, R′4 and R′5. The common tangent is inclined about 30 ° with respect to the horizontal.
[0028]
On the other hand, the rear end portion of the base surface side guide plate member 34 of the guide member 32 forms a guide surface 34a facing downward and extending horizontally, and the rear end portion of the emulsion surface side guide plate member 36 is upward. A guide surface 36a that faces and extends horizontally is formed. Therefore, the front end of the photographic paper 1 conveyed by the intermediate roller groups R′3, R′4, R′5 in the vicinity of the intermediate portion of the guide member 32 is not the emulsion surface side guide plate member 36 side. It always enters obliquely (with an entry angle of about 30 °) toward the horizontal guide surface 34a on the base surface side guide plate member 34 side. Then, the photographic printing paper 1 keeps its bending point on the guide surface 34a on the basis of the pushing force by the second roller pair R'6, R'7 as the conveyance progresses. The pair of transport rollers 30 in the development processing tank unit 13 is pulled out from the guide member 32 in a state where it contacts the lower surface of the rear end portion of the surface side guide plate member 34, that is, on the horizontal guide surface 34 a through friction. , 30.
As can be understood from FIG. 6, the curved portion near the middle portion of the guide member 32 also has a shape that is curved in the direction opposite to the curl direction of the photographic paper. In the case of the general photographic paper 1 having a ridge, the base surface side guide plate member 34 always passes through the base surface side of the photographic paper 1 even when passing through other parts including the vicinity of the intermediate portion of the guide member 32. The emulsion surface side of the photographic paper 1 is less likely to be damaged by friction with the stationary guide member.
