Description

  The present invention relates to a photosensitive material processing apparatus.

  Photosensitive material processing equipment is a processing tank that contains processing liquids for development, bleaching, and washing after exposure and printing on the emulsion surface of photographic paper (hereinafter referred to as paper) that has been cut into a predetermined size. The apparatus is configured to be transported so as to pass sequentially, and then dried and discharged to the outside.

  Such a photosensitive material processing apparatus generally conveys paper obtained by cutting a long roll paper into a predetermined size in advance, exposes the paper in a dark room, and then sequentially passes through the processing liquid tank. It is configured to discharge. Recently, an apparatus having various sorting functions has been proposed, such as sorting out discharged paper into units ordered by customers.

  For example, Japanese Patent Laid-Open No. 11-349201 discloses a mechanism for feeding out paper conveyed in a plurality of rows while aligning it with end rows.

  Further, in Japanese Patent Laid-Open No. 2002-156736, when there is paper that has been printed by interruption with respect to paper that has been printed for each order, the transport direction of the discharged paper is changed to A function is disclosed for separating paper formed by interruption and paper formed for each order.

Furthermore, in Japanese Patent Laid-Open No. 2003-173011, in addition to a mechanism for separating and sending in order units by customers by performing intermittent driving, it is possible to take out the printed screen by flipping the printed paper. This mechanism is disclosed.
JP 11-349201 A JP 2002-156736 A JP 2003-173011 A

  However, any of the above-described techniques is based on the premise that discharged and sorted paper (paper on which images are formed) is normally fed out and the operator sequentially takes out the fed paper. On the other hand, an operator who operates such a photosensitive material processing apparatus does not always monitor the state of the photosensitive material processing apparatus and may be busy with other work. For this reason, in the said prior art, if taking out of the separately sent out paper is delayed, the important paper of the customer will be scattered on the floor surface. On the contrary, even when the operator is urgently taking out the paper, the operator waits for the paper to be sent out to a predetermined position, which is not convenient for the operator. Furthermore, if the paper is not sent out normally due to equipment troubles related to the sorting function, the sorting equipment will be clogged with the discharged paper unless the operator moves the discharged paper to another location. There is also a problem such as that, and in this respect, convenience is poor. For this reason, in a photosensitive material processing apparatus having such a sorting function, it is required to add a function that can flexibly cope with an operator's work state and an apparatus operation state.

  The present invention has been made in view of the above problems, and an object of the present invention is to improve convenience in a photosensitive material processing apparatus having a sorting function for sorting printed and discharged photosensitive materials.

In order to achieve the above object, a photosensitive material processing apparatus according to the present invention comprises the following arrangement. That is,
A photosensitive material processing apparatus comprising a sorting means for sorting a photosensitive material formed and discharged,
A first conveying means for placing the discharged photosensitive material and continuously conveying the photosensitive material;
Reversing means for reversing the front and back of the photosensitive material continuously conveyed;
A second conveying means for performing intermittent driving to maintain a stopped state until a predetermined number of photosensitive materials reversed by the reversing means are stacked, and to drive when a predetermined number of photosensitive materials are stacked;
Instructing means for forcibly driving the second transport means,
The second transport unit is driven a predetermined distance when an instruction for forced operation is received from the instruction unit.

In order to achieve the above object, another photosensitive material processing apparatus according to the present invention comprises the following arrangement. That is,
A photosensitive material processing apparatus comprising a sorting means for sorting a photosensitive material formed and discharged,
A first conveying means for placing the discharged photosensitive material and continuously conveying the photosensitive material;
Reversing means for reversing the front and back of the photosensitive material continuously conveyed;
A storage unit that is disposed at a position facing the reversing unit with respect to the first conveying unit, and stores the photosensitive material;
A second conveying means for performing intermittent driving to maintain a stopped state until a predetermined number of photosensitive materials reversed by the reversing means are stacked, and to drive when a predetermined number of photosensitive materials are stacked;
Monitoring means for monitoring the transport state of the second transport means,
When the monitoring unit determines that the transport state of the second transport unit is not normal, the transport direction of the first transport unit is reversed, and the photosensitive material is stored in the storage unit. And

  The monitoring unit may determine that the conveyance state is not normal when the predetermined number of bundles of the photosensitive material are loaded on the second conveyance unit.

  Furthermore, the monitoring means determines that the conveyance state is not normal when the intermittent drive operation is not normally terminated.

  According to the present invention, convenience is improved in a photosensitive material processing apparatus having a sorting function for sorting the photosensitive material formed and discharged.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the accompanying drawings. First, the outline of each embodiment will be briefly described. According to the first embodiment, in addition to the function of feeding out the paper P separated by performing intermittent driving, a function for further forcible driving is added, and when a predetermined button is pressed, intermittent driving is performed. By forcibly transporting the paper P to a predetermined position without performing the operation, even if the operator is in a hurry to take out the paper P, the operator can flexibly cope with the function. In addition, according to the second embodiment, even when the removal of the sorted paper P is delayed or when the sorting function has failed, the transport control is performed so that the discharged paper P is put in the tray. By doing so, it is possible to temporarily avoid that the sorting mechanism overflows or the paper is scattered by the discharged paper. Each embodiment will be described in detail below.

[First Embodiment]
<Photosensitive material processing equipment>
FIG. 1 is a front view of the photosensitive material processing apparatus (hereinafter, also referred to as “apparatus 1”) with all covers detachably provided to the housing 2 in order to show the main part of the overall configuration.

  In this figure, the device 1 is configured to be as flat as possible in the front and back direction of the paper surface, so as not to occupy the occupied area after installation, while allowing easy access to the main parts from the front side. Considered. Further, the roll paper RP wound with the color emulsion surface side to be a printing screen of the paper P outward is wound around a core as a continuous long roll having a predetermined width dimension (for example, 89 mm width), and light. The paper magazine 3 is provided so as to be rotatable in a light-shielding state in which the paper is completely blocked, and a roll paper RP is detachably incorporated by opening a lid (not shown) in the dark room.

  The paper magazine 3 is provided so that it can be pulled out from the front side toward the front side, and is configured to be set at a predetermined position shown in the figure by moving to the back side after loading. The paper magazine 3 is provided with a handle (not shown).

  Further, an automatic opening / closing mechanism (not shown) for automatically opening the communication opening when the built-in roll paper RP is discharged in the direction of the arrow toward the outside of the paper magazine 3 is provided. The three openings can be automatically opened and closed and supplied as shown.

  A cutter unit 4 is disposed in the vicinity of the opening of the paper magazine 3. The cutter unit 4 is provided for cutting the roll paper RP immediately after being fed out from the communication opening of the paper magazine 3 into a desired cut size before exposure. The cutter unit 4 uses the predetermined cut size. The paper P that has been cut into two parts is sequentially sent to the exposure position of the exposure table 5 disposed in the bottom surface portion of the dark box 7.

  For this transport, the exposure table 5 has a built-in suction transport mechanism for transporting the back surface of the cut paper P by sucking the transport surface to the exposure position. This suction conveyance mechanism has a rotation function for rotating the paper P by 90 degrees in addition to the function of temporarily sucking the paper P at the exposure position and holding it in a stationary state.

  As described above, when preparation for exposure is completed, the film F is sequentially fed to the exposure unit 6 and an optical system 9 including a zoom lens is automatically or manually adjusted to form an image of a desired size. An image is formed on the paper P and exposed. Further, the rotation function is configured to perform exposure of a plurality of types of sizes by turning 90 degrees after the paper P is sucked by the suction pad.

  After this exposure, the paper P is transported toward the transport unit 10 in the direction of the arrow D1, and it is transported in the downstream direction after it is determined whether or not it is a large paper at an intermediate position. Here, when the paper size is small (for example, 127 × 89 mm), the paper is distributed left and right by the distribution device 12 and conveyed in two rows, and each processing liquid tank 16 provided in the second chamber 14 on the downstream side. The inside is conveyed in two rows.

  By carrying in two rows in this way, the processing speed can be increased. Further, even in the case of a portrait such as a panoramic photograph (254 × 89 mm), it can be conveyed in two rows in the same manner.

  On the other hand, when it is desired to perform exposure so as to be orthogonal to the transport direction of the film F loaded in the exposure unit 6, the paper P held by suction by the rotation function is rotated 90 degrees for exposure. . In this way, a plurality of types of differently sized papers P can be exposed with the same type of width dimension.

  The dark chamber 7, the exposure table 5, and the transport unit 10 described above are the first chambers formed so that each processing liquid stored in the processing liquid tank 16 is not affected by the gas generated by vaporization due to temperature rise or the like. 13 is disposed inside.

  For this purpose, the first chamber 13 is provided with a partition wall 11 between the first chamber 13 and the second chamber 14, and the photosensitive material transport device 15 disposed in the communication opening provided in the partition wall 11. As a result of the transport operation, the paper P is transported in the direction of the arrow D2 in the drawing, and the vaporized gas of the processing liquid stored in the processing liquid tank 16, for example, is stored in the second chamber so as to always close the communication opening. It is configured not to enter the first room 13 from 14. Furthermore, the internal pressure of the first chamber 13 is maintained at the second chamber 14 or higher so that the vaporized gas does not enter the dark room side and everything is done.

  The cutter unit 4, the exposure table 5, the transport unit 10, and the photosensitive material transport device 15 are configured so that they can be easily pulled out to the front side of the housing 2 without using tools, and the paper jam is released. In addition, various inspection operations can be easily performed.

  After passing through the photosensitive material transport device 15 in the direction of the arrow D2, the paper P is transported toward the downstream side by the transport rack device 17 so that development processing of the paper P after exposure is performed. Specifically, the developing process is performed in the processing liquid tank 16 while the direction is changed in the direction of arrow D3 and sent. The transport rack device 17 is configured so that it can be individually set in each processing solution tank 16 as shown in the figure after the ceiling member 29 provided so as to be openable and closable with respect to the housing 2 is opened upward. Yes. And when performing the cleaning operation | work for removing regularly the solidified component etc. of the process liquid adhering to the conveyance roller of each conveyance rack 17, it can take out outside after moving the conveyance rack 17 upwards. It is configured.

  In addition, each transport rack 17 is driven in synchronism with each transport roller of the transport rack 17 by being transmitted power from a common drive motor 20 shown by a broken line through a power transmission mechanism using a worm gear or a chain. The speed difference is not generated in the conveying roller.

  In the transport operation by the transport rack 17, the leading end of the paper P is guided by the guide device 18 disposed above each processing liquid tank, and the direction is changed in the direction of the arrow D4 to perform bleach-fixing. It is sent to the next treatment liquid tank 16. After that, it is transported as shown in the figure and finally guided out so as to change direction in the direction of arrow D5 after leaving the processing liquid tank 16 for performing the stabilization process, and sent to the drying device 22.

  The drying device 22 performs drying by spraying hot air on the marking screen Pa of the paper P through the nozzle during the conveyance as shown by the broken line, and then conveys the paper upward.

  Above the drying device 22, a direction changing roller 23 which is a discharging means for discharging the paper P to the outside with the marking screen Pa facing down, an idle roller 24 driven by the direction changing roller 23, and a driving roller 25. And an idle roller 24 that is driven by the drive roller 25, and is conveyed at a nip formed between the rollers so that the paper P after drying is discharged with the marking screen Pa facing down. It is configured.

  Through the above steps, the completed paper P is discharged to the outside of the photosensitive material processing apparatus 1 with the marking screen Pa facing down.

  The paper P discharged with the marking screen Pa facing down is dropped on the first belt conveyor 30 that is continuously driven in a direction orthogonal to the discharge direction, and then the front and back are reversed by the reversing device 31. Then, it is dropped on the second belt conveyor 32 after the marking screen Pa is turned up. The second belt conveyor 32 maintains the state where the paper P, which is turned upside down, for example, is stopped until the number of sheets corresponding to one order is stacked, and when the number of sheets corresponding to one order is reached, it is driven to the front side of the drawing sheet. The so-called intermittent drive is performed. The paper P sent out to the front side of the paper surface while being intermittently driven reaches the end of the second belt conveyor 32 and is taken out by the operator.

  A power supply unit is provided in the housing 2 that occupies the space below the drying device 22. On the power supply unit, the above-described treatment liquid tanks 16 are controlled and separation control described later is performed. A processor control unit 100 is provided, and is configured to control the entire apparatus.

<Configuration of paper P sorting mechanism>
FIG. 2 is a view taken along the line X-X in FIG. 1. In this embodiment, the mechanism (first and second belt conveyors 30 and 32 for conveying and reversing the discharged paper P is shown in FIG. ) And the reversing device 31) are collectively referred to as a sorting mechanism.

  In this figure, components that have already been described are denoted by the same reference numerals and description thereof is omitted. The driving roller 25 and the idle roller 24 are directed to the paper P so that they are directed toward the ceiling surface 29a of the ceiling member 29. Is discharged onto the first belt conveyor 30 by being discharged in a double row state as shown. In the case of a large size, the paper is dropped onto the first belt conveyor 30 in a single row state, and is conveyed so that the back surface Pb of the paper P faces up and falls onto the tray 33. A push button 47 is a switch for forcibly transporting the second belt conveyor 32 (details will be described later).

  On the other hand, the normal size paper P is guided by a reversing device 31 composed of a belt body that is stretched so as to be driven and driven at one rotating shaft support portion of the first belt conveyor 30, and is printed on the screen. It is dropped onto the second belt conveyor 32 with Pa on the top. In addition, the distance l in a figure shows the movement distance for one intermittent drive. When the paper P is sent out to the position of the distance L, the operator takes out the paper (paper indicated by a dotted line in the figure).

  FIG. 3 is a three-dimensional exploded view showing a configuration example of the second belt conveyor. The second belt conveyor 32 has left and right bases 35 and 36 as a base portion, and bearings provided on these bases support a belt roller 37 and a driving belt roller 38, and endlessly between these rollers. The belt 40 is provided in a stretched state. A toothed pulley 41 is fixed to the core of the drive belt roller 38, and a toothed belt stretched between the toothed pulley 43 fixed to the output shaft of the stepping motor 44 fixed to the base 35. The driving force can be transmitted to the driving belt roller 38 by 42. With this configuration, the paper P is transported by intermittently driving the belt 40 in the direction of the arrow D6 in the drawing as the stepping motor 44 is driven.

<Operation of paper P sorting mechanism>
Next, the operation of the sorting mechanism for sorting the paper P that has been printed and discharged will be described in detail with reference to FIGS. FIG. 4 is a functional block diagram for separating the discharged paper P. In this embodiment, the separation control unit 400 is realized as a part of the above-described control unit 100. Various information (operation start command, size information, number information) to the sorting control unit 400 is input from a control unit that controls the entire photosensitive material processing apparatus.

  In FIG. 4, reference numeral 401 denotes a first belt conveyor control unit, which receives an operation start command and receives a first belt conveyor driving unit 404 (a first belt conveyor such as a first belt conveyor, a belt roller, and a stepping motor). The mechanisms to be driven are collectively referred to as “first belt conveyor driving unit.” (Hereinafter the same applies to 405 and 406). Also, an operation start command is issued to the reversing device control unit, and thereby the reversing device driving unit 406 is operated.

  Further, the first belt conveyor control unit controls the transport direction of the paper P by the first belt conveyor driving unit 404 based on the size information. Furthermore, when the number information is received and the number of orders is reached, the second belt conveyor control unit 402 is instructed to start intermittent driving. When the second belt conveyor control unit receives an instruction to start intermittent driving, the second belt conveyor driving unit 405 moves the second belt conveyor driving unit 405 to a predetermined distance (see the distance l in FIG. 2, that is, the length of the paper P and the loaded paper P After driving for a distance (corresponding to the interval), stop.

  When the second belt conveyor control unit 402 receives a signal from the push button 47, the second belt conveyor control unit 402 receives only a certain distance (refer to the distance L in FIG. 2), regardless of whether or not there is an instruction to start intermittent driving. It is controlled to forcibly drive (to a position that is longer than the distance l and allows the operator to take out the stacked paper P).

  FIG. 5 is a flowchart showing a processing flow in the first belt conveyor control unit 401 and the reversing device control unit 403. The process starts upon receiving the operation start command. In step S501, size information is acquired, and it is determined whether the paper is a large size paper based on the size information (step S502).

  If it is determined in step S502 that the size is large, the process proceeds to step S503, and the stepping motor 44 is driven in the reverse direction. Thereby, the large-sized paper is conveyed to the tray 33.

  On the other hand, if it is determined in step S502 that the size is not large, the stepping motor 44 is driven in the forward direction (step S504). In step S505, the number information is received and it is determined whether or not one order of paper P has been conveyed (step S506).

  If it is determined in step S506 that the paper P for one order has not been transported, the transport is continued until the paper P for one order is transported. On the other hand, when it is determined that the paper P for one order has been conveyed, the process proceeds to step S507, and an intermittent drive start command is transmitted to the second belt conveyor control unit 402. After transmitting the intermittent drive start command, the process returns to the start again.

  FIG. 6 is a flowchart showing the flow of processing in the second belt conveyor control unit 402. As in FIG. 5, the process starts when an operation start command is received. First, in step S601, it is confirmed whether or not the push button 47 is pressed. If the push button 47 has been pressed, the process proceeds to step S605 to start forced driving, and after driving for a predetermined distance L, stops (step S606). As a result, the paper P already loaded on the second belt conveyor is conveyed to a position where the operator can take it out.

  On the other hand, if the push button 47 has not been pressed, the process proceeds to step S602, where it is confirmed whether an intermittent drive start command has been received from the first belt conveyor control unit 401 or not. If not received, the process returns to step S601. In other words, in steps S601 and S602, the process waits until either the push button 47 is pressed, an intermittent drive start command is received, or any processing is performed. If an intermittent drive start command is received, the process proceeds to step S603 to start intermittent drive. When driving for a certain distance l, the driving is stopped (step S604). When either forced driving or intermittent driving is completed, the process returns to the start.

  As is clear from the above description, according to the present embodiment, when the push button 47 is arranged and the push button is pressed, the paper P sorted for each order is forced to a predetermined position where it can be taken out. By making it carry, when the operator is urgently taking out the paper P, the paper P can be taken out quickly without waiting for the conveyance by intermittent driving. As a result, convenience in the photosensitive material processing apparatus is improved.

[Second Embodiment]
In the first embodiment, the function for quickly removing the paper P when the operator is urgently taking out the paper P has been described. However, in the present embodiment, when the operator has taken out the paper P late, A function for dealing with a failure in the sorting function will be described.

  FIG. 7 is a diagram illustrating a configuration of a paper P sorting mechanism according to the present embodiment. In addition, the same code | symbol is attached | subjected to the part which is common in FIG. Here, components different from those in FIG. 2 will be described.

  In the figure, reference numeral 48 denotes a sensor, which is arranged on the exit side in the traveling direction of the second belt conveyor 32. The sensor 48 detects that the paper P has been conveyed to the position as an abnormality. That is, when a predetermined number of bundles of the paper P are loaded on the second belt conveyor 32, it is determined that the operator has taken out the paper P late. As shown in FIG. 8 (a diagram showing the configuration of the second belt conveyor), the belt 50 of the second belt conveyor 32 is provided with openings 49 having a constant length at regular intervals, and a sensor 48. Can detect the presence or absence of paper P and the presence or absence of failure of the second belt conveyor 32 from the opening 49. Here, the interval between the openings is equal to the distance l moved by one intermittent drive, and the opening length of the opening 49 is shorter than the distance moved by one intermittent drive. One aperture is designed to pass over the sensor 48 per drive.

  Next, a method for detecting the presence or absence of the paper P by the sensor 48 will be described with reference to FIG. In the same figure, (B) shows various ways of placing the paper P with respect to the opening 48. In the case shown in 905, when there is no paper P, the paper P covers half of the opening 49. When the paper P is placed so that the paper P covers about 3/4 of the opening 49, the paper 908 is placed so that the paper P completely covers the opening 49. Indicates the case. Further, reference numerals 901 to 904 in (A) denote detection signals of the sensor 48 corresponding to the respective mounting states indicated by 905 to 908, and indicate outputs for one intermittent drive.

  As indicated by reference numeral 901, when there is no paper P, the opening 49 passes over the sensor 48 while the time for one intermittent drive elapses, so that a predetermined amount of OFF time exists. That is, if a predetermined amount of OFF time is present while the time for one intermittent drive has elapsed, it is determined that the paper P has not been conveyed to the position of the sensor 48.

  On the other hand, as shown in 902 and 903, when the paper P covers a part of the opening 49, the OFF time is shortened. Therefore, in such a case, it can be determined that the paper P has been transported to the position of the sensor 48. Further, as shown at 904, when the paper P completely covers the opening 49, the OFF time becomes 0 even though the time for one intermittent drive has elapsed, and similarly, the sensor 48 It is determined that the paper P has been transported to the position.

  Next, a failure detection method of the second belt conveyor 32 by the sensor 48 will be described with reference to FIG. In the same figure, (B) shows the positional relationship between the opening 49 and the sensor 48, and the signal output of the sensor 48 in each positional relationship (1004 to 1006) is shown as 1001 to 1003 in (A).

  When the second belt conveyor 32 normally performs intermittent driving (1001), since one opening 49 passes over the sensor 48 during the time of one intermittent driving, a predetermined amount of OFF time is reached. Occur.

  On the other hand, when the second belt conveyor 32 does not operate despite receiving an intermittent driving start command (when the second belt conveyor 32 stops operating at a portion other than the opening 49), the output of the sensor 48 is It is always on and the off time is zero. Further, when the second belt conveyor 32 stops operating when the opening 49 comes on the sensor 48, the output of the sensor 48 is always in the OFF state as indicated by 1003.

  In this way, the determination is made based on whether or not the output from the sensor 48 during one intermittent drive has a predetermined amount of OFF time. That is, when the predetermined amount of OFF time is present, it can be determined that the second belt conveyor 32 is normally intermittently driven and the paper P has not reached the position of the sensor 48. On the other hand, if there is no predetermined amount of OFF time, either the intermittent drive of the second belt conveyor 32 has failed, or the intermittent drive is normal but the paper P has reached the position of the sensor 48. It can be judged.

  FIG. 11 is a flowchart showing the flow of processing in the second belt conveyor control unit 402. When an intermittent drive start command is received in step S1101, the signal output of the sensor 48 is read in step S1102, and it is determined in step S1103 whether a predetermined amount of OFF signal has been received.

  If it is determined that there is a predetermined amount of OFF time, it is determined that the second belt conveyor 32 is operating normally and the paper P has not reached the position of the sensor 48 (step S1105), and the process is started again. Return to.

  On the other hand, if it is determined that the predetermined amount of OFF time has not been reached, it is determined that the second belt conveyor 32 has not operated normally or the paper P has reached the position of the sensor 48. (Step S1104), an abnormal signal is transmitted to the first belt conveyor control unit 401 (Step S1105).

  FIG. 12 is a flowchart showing the flow of processing in the first belt conveyor control unit 401. In step S1201, it is determined whether an abnormal signal is received from the second belt conveyor control unit 402 or not. If it is determined that an abnormal signal has been received, the process proceeds to step S1205, the stepping motor 44 is driven in the reverse direction, and the discharged paper P is temporarily sent to the tray 33. As described above, when the intermittent driving is not normally performed on the second belt conveyor, or when the paper P reaches the position of the sensor 48, the paper P is continuously fed to the second belt conveyor 32. Then, the second belt conveyor 32 overflows or the separated paper P falls from the end of the second belt conveyor 32 to the floor surface. Therefore, in order to avoid such a situation, when a signal notifying the abnormality arrives from the second belt conveyor 32, the transport direction of the first belt conveyor 30 is reversed, and the discharged paper P is transferred to the second belt. Instead of being conveyed to the conveyor 32, the tray 33 is temporarily avoided.

  If no abnormality signal is received in step S1201, it is determined that the paper P can be conveyed to the second belt conveyor, and the size information is stored as in the first embodiment. In the case of large size, the conveyance direction is reversed, but in the case of not large size, the conveyance direction is left in the forward direction (steps S1202 to 1204), and the process returns to the start.

  As is clear from the above description, according to the present embodiment, the conveyance direction of the first belt conveyor is reversed when the operator takes a delay in taking out the paper P or when a failure occurs in the second belt conveyor. Then, by temporarily sending the discharged paper P to the tray, it is possible to prevent the second belt conveyor from overflowing paper or the separated paper P from being scattered on the floor surface.
