The present invention relates to a film transfer apparatus capable of continuously transferring the film exposed to the developing portion of the automatic film developing machine.

In general, when developing the film in an automatic film developing machine of the type in which the film is transported by the reader as shown in FIG. 16, the end of the film 121 removed from the patron 120 is the adhesive tape 124. Is connected to the reader 122.

The leader 122 is a flexible plate made of synthetic resin and having a plurality of square holes 123 arranged longitudinally at equal intervals. A sprocket is provided to transfer the leader 122 in the longitudinal direction toward the film developing portion by engaging the square hole 123.

Two rolls of film 121 are connected to one leader 122 at a time. In developing the film 121, the leader 122 and the patron 120 are inserted into the film setting chamber in the film insertion container provided in the automatic film developing apparatus, and the patron 120 is supported by the patron holder. Thereafter, the leader 122 is moved to extract the film 121 from the patron 120 and to transfer the film to the film developing unit.

If the film is transferred from the film setting chamber toward the developing part while the film setting chamber is open, the film will be exposed to the light beam.

Therefore, when developing a large number of films, the film had to be set in the film setting chamber only after the previous film was completely transferred into the film developing unit. Thus, when the film is transferred into the film developing section, each pair of films may be spaced apart by a long distance from the film of the previous pair. This is undesirable because the capability of the film developing portion is not sufficiently utilized.

In order to solve this problem, there is an improved film transfer device disclosed in Japanese Patent Laid-Open No. 63-23155, in which a plurality of film cases are provided in a magazine spaced apart from each other. This magazine is set in the film insertion container, and the film in each film case is transferred one by one toward the developing part.

With a film transfer device using such a magazine, it is impossible to add a film while developing the film. Moreover, since a plurality of films are developed in batch units, a space is generated between the film and each time the magazine is replaced with a new one. Therefore, the film developing ability is lowered.

Moreover, the magazine is detachably connected to the upper portion of the film insertion container, so handling is difficult. In addition, much of the magazines project outward when connected. This increases the overall size of the automatic film developing machine, thus increasing the installation space. Also, if the films are to be developed one at a time, the magazines must be removed. Therefore, it is necessary to provide extra space for storing such removed magazines.

An object of the present invention is to provide a compact film transfer apparatus capable of continuously transferring a film to a film developing unit without such a problem.

According to the present invention, there is provided a film conveying apparatus for conveying a film drawn out from Patron and attached to a leader into a film developing unit, the film conveying device being connected to the film developing unit in a film setting chamber and a pattern.

In order to transport it to the reader to guide the reader, and film processing portion provided in the film setting chamber it is composed of an infeed device provided in the film setting chamber.

By continuously transferring the patrons containing the film in this arrangement together with the leader into the slots, the patron attached readers can be transferred one by one into the film developer. This improves the capability of automatic film developing.

In addition, since the film setting chamber is provided below the film transfer chamber, the overall size of the automatic film developing apparatus can be reduced.

The first conveying device in the film conveying chamber may be composed of a conveying device for supporting the bottom edge of the leader and a driving device for vertically moving the conveying device. Such a carriage can be provided as a support member to prevent the hanging Patron from falling from the leader and thus prevent the film therein from being pulled out of the Patron and exposed to light.

In another arrangement, the support member has a rear end pivotally connected to the carriage, the roller is mounted on the support member at the front and the bottom of the pivot center of the support member, and the roller guide groove is supported by guiding the roller. In order to control the position of the member is provided to extend vertically along the vertical path of the conveyance port, the lower portion of each roller guide groove is in the form of an inclined guide path so that the support member rotates downward.

In this arrangement, the patron will not interfere with the support member even if the patron under the leader that has been transported into the second transporter is located near the path of the leader transported by the first transporter. Thus, the plurality of readers can be supported by the second conveying device.

The film conveying apparatus further includes a detector provided along a path of the reader conveyed downward by the first conveying apparatus to detect the amount of warpage of the reader and control means for controlling the second conveying apparatus by the detection signal from the detector. can do. This arrangement is quite curved so that all the adhered leader during transfer can be removed before being transferred into the film developer.

The second conveying device may include a pair of leader guide drives, each leader guide drive includes a pair of rotary shafts, pulleys mounted on the rotary shafts in the upper and lower portions, a belt wound around the upper and lower pulleys, And a plurality of leader guides each having a vertically extending support groove for accommodating one of the side edges of the leader and arranged at equal intervals between the upper and lower belts.

The film conveying device is an alarm for alarming the fall of the patron according to the detection signal of the detector and the detector provided under the path of the patron and the reader conveyed by the second conveying device for detecting the fall of the patron. Means may further comprise. With this arrangement, the operator can close the slot with the cover before the film is exposed to the light beam. The film is thus prevented from being exposed to light.

The film transfer device includes a patron supported by a leader guide facing the first conveying device of the reader guide drive unit, or a first detector for detecting a reader and a patron supported by the leader guide facing the third conveying device. Or the supply of the reader into the second detector and the slot for detecting the reader is temporarily stopped and then resumed so that the reader or patron is detected by the second detector while the first detector is not at all. If not detected, the control device further moves the reader guide toward the first carrier until the reader or patron is detected by the first detector and then moves the leader guide by one pitch toward the third carrier. It may include.

With this arrangement, it is possible to set the leader in this empty guide once the supply of the reader is continued again, even if some leader guides are driven toward the third carrier with the leader supply temporarily stopped when the supply of the leader is temporarily stopped. Do. Therefore, subsequent film processing can be performed effectively without wasting time.

The third conveying device may be composed of a conveying device for supporting the bottom edge of the leader and a driving device for moving the conveying device up and down.

The film feeder also controls the infeed device according to the detection signal of the film detector and the film detector provided along the path of the reader conveyed upward by the third conveying device for detecting whether the film is pulled out of the patron. It may further include a control means for. This arrangement makes it possible to remove all films drawn out of Patron before being transferred into the film setting chamber. Thus the film is protected from damage.

The film transfer device detects whether the leader immediately after the leader conveyed upward by the third conveying device is moved upward with the leader in front of it, and the detector is provided above the reader immediately after the leader conveyed upward. The apparatus may further include a control device for controlling the driving unit of the third conveying device according to the detection signal of the detector. This arrangement can prevent any two adjacent liars from being transferred simultaneously into the film setting chamber.

As shown in FIG. 1, the film insertion container 2 provided after the film developing unit 1 is divided into a film setting chamber 3 and a film transfer chamber 4.

The film setting chamber 3 is connected to the film developing part 1 through the passage 5. The top part has a cover 6. The lid 6 is pivotable around the pin 7.

The film setting chamber 3 and the film transfer chamber 4 are separated by a partition plate 8 having an opening 9 closed by a shutter 10.

The film transfer chamber 4 has a cover 11 in front of it. The cover 11 is pivotable around the pin 12 and has a slot 13 into which the leader 122 and Patron 120 (see also FIG. 16) are inserted. The slot 13 is closed by a cover 17 which is pivotable about the pin 16. The leader 122 and the patron 120 are inserted with the patron 120 positioned below the leader 122.

The first film transport device 18 for transporting the reader 122 inserted through the slot 13 downward is mounted in the film transport chamber 4. The film transport apparatus 18 is a toothed pulley (19, 20), the toothed pulley (22) driven by the motor 21, respectively provided in the upper and lower portions in the film transfer chamber (4), pulleys (19, 29, 22) The timing belt 23 wound around the circumference | surroundings) and the conveyance port 24 fastened to the timing belt 23 are comprised. The conveyance port 24 can move up and down by driving the motor 21.

Limit switches 25 and 26 are provided at the upper and lower ends of the path of the delivery port 24, respectively. The limit switch 25 or 26 is activated when the carriage 24 reaches the upper and lower ends to stop the motor 21.

As shown in FIGS. 2 to 4, a pair of vertical guide plates 27 is provided on both sides of the path of the conveying tool 24. The guide plate 27 is provided with the vertically extending guide grooves 28 on the surfaces facing each other (FIG. 2). The delivery port 24 moves up and down along the guide groove 28.

The carriage 24 has a guide groove 29 on its top surface to support the leader 122 at the center of the bottom edge. A pair of support plates 30 are also provided on both sides thereof (Fig. 5). The pin 31 is provided below the outer surface of each support plate 30. Support 32 supporting Patron 120 has a rear end pivotally supported on each pin 31 (FIG. 5).

The roller 33 is rotatably mounted to the inner surface of each support 32 in front of and below the pin 31. On the other hand, the guide plate 27 has a roller guide groove 34 for guiding the roller 33 and for controlling the position of the support 32.

Each roller guide groove 34 is composed of an upper guide path 35, an inclined guide path 36, and a lower guide path 37. The upper guideway 35 and the lower guideway 37 extend in parallel with the guide groove 28 to guide the movement of the carriage 24. The support 32 is actually kept horizontal as each roller 33 moves along the upper guideway 35. As each roller 33 moves along the inclined guideway 37, the support 32 is inclined thereafter. The support 32 is still inclined downward as each roller 33 moves along the lower guideway 37. The spring 38 presses the rear portion of each support 32 upwards.

As shown in FIG. 6, one of the guide plates 27 supports the detector 39 which detects the amount of warpage of the reader 122 on its outer surface, while being conveyed downward by the conveyer 24. . This detector 39 is composed of a reader detection arm 40 and a switch 41. The leader detection arm 40 has a rear end pivotally supported on the pin 42. The front end protrudes into the path of the leader 122 which is conveyed downward by the conveyer 24. When the leader 122 is moved downward, the leader 40 pushes and rotates the arm 40 to operate the switch 41.

With the carriage 24 of the first conveying device 18 stopped in its upper position, the leader 122 shown in FIG. 16 is inserted into the slot 13 with the Patron 120 disposed thereunder. The bottom edge of the leader 122 is inserted into the support groove 29, at which time a switch (not shown) is activated and the motor 21 is also operated, such that the carriage 24 and the leader 122 attached thereto are mounted. Begins to descend.

When the support 32 starts to descend, the roller 33 mounted on the support moves along the upper guide groove 35 of the roller guide groove 34 to keep the support 32 actually horizontal. Patron 12 supported on the support 32 is conveyed downward.

Therefore, when the leader 122 descends, the patron 120 will be prevented from falling off the support 32 so that the film 121 in the patron 120 will not be pulled at all.

When the roller 33 enters the inclined guideway 36, the support 32 is inclined downward and separated from the patron 120, as shown in FIG.

And the roller 33 moves into the lower guideway 37, where the support 32 is actually kept vertical. When the carriage 24 moves further downward to operate the lower limit switch 26, the motor 21 stops.

When the leader 122 reaches the lower portion of the film transfer chamber 4, the leader 122 moves intermittently for a predetermined stroke to the inner portion of the film transfer chamber 4 by the second conveying device 50 (a fifth Degree).

2 and 7 show the second conveyance device 50 in detail. It consists of a pair of drive unit 51 for reader guides.

Each leader guide drive unit 51 has a pair of rotary shafts 52, a toothed pulley 33 mounted on the upper and lower portions, one wound around the upper pair of pulleys 53 and the other wound around the lower pair. Is composed of a timing belt 54. The leader guide part 55 is fastened to the timing belt 54 at equal intervals. Each leader guide 55 is formed with a vertically extending support groove 56.

The left and right leader guide drive units 51 are simultaneously driven by a single motor 57. The leader guide 55 is intermittently conveyed in the direction of the arrow shown in FIG. 2, and the feeding stroke is equal to the distance between the adjacent leader guides 55.

The pair of leader guide drive units 51 are provided with a pair of reader guides 55 facing each other on and below both sides of the slot 13 (FIG. 1) and inserted into the slot 13. Are arranged to be received at both sides of the support groove 56 in the leader guide 55 (FIG. 7). Therefore, both sides of the leader 122 are guided along the support grooves 56 formed in the pair of leader guides 55 when the leader 122 is transported downward.

The bottom surface of the support groove 56 formed in each leader guide 55 is directly above the lower end of the carriage 24 stroke. Therefore, the leader 122, which is conveyed downward by the carriage 24, touches the bottom of the support groove 56 just before the carriage 24 stops at the lower end of the stroke. Reader 122 thus passes from first carrier 18 to second carrier 50.

The support 32 of the carriage 24 will be in a substantially vertical position just before the bottom edge of the leader 122 touches the bottom of the support groove 56. And even if the leader 122 already conveyed by the second carrier 50 is positioned closely to the next leader, the support 32 will not be interfered by the Patron 120. Therefore, the pitch can be shortened between the leader guides 55. The shortened pitch means can have a larger number of leader guides 55 and also make it possible to support a larger number of readers 122 in turn by the second conveyer 50.

If the pitch between the leader guides 55 is large enough not to interfere with the Patron 120, the support 32 is fixedly mounted to the carriage 24 even though the support 32 actually moves downward while maintaining the horizontal position. Can be.

When the reader 122 passes from the first transporter 18 to the second transporter 50 and the lower limit switch 26 is actuated by the transporter 24 of the first transporter 18, the leader guide The pair of drive units 51 is driven by a motor 57 and the reader 122 is intermittently transported further into the film transfer chamber 4 so that the distance of each intermittent travel is between the leader guides 55. The same as the mounting pitch.

If the reader 122 conveyed by the second conveying device 50 is a flat normal leader, the switch 41 of the detecting means 39 shown in FIG. 6 is turned on from off as the reader 122 moves. Changes to

However, if the reader 122 is in an abnormal state bent in the width direction as shown in FIG. 8, the switch 41 will remain ON while the leader 122 is being transferred.

If the switch 41 is not switched from the ON state to the OFF state while the leader 122 is being transported by the second transport device 50, then the control device may be configured to control the first transport device 18. The reader is stopped by controlling the motor 21. It also activates the alarm and indicates that the reader is not available.

Each time the reader 122 is transferred from the first conveying device 18 to the second conveying device 50, the leader 122 is conveyed further into the film conveying chamber 4 by the second conveying device 50.

At the bottom of the path of the leader 122 conveyed by the second conveyer 50, the film 121 in the Patron 120 is pulled away from the leader 122 conveyed by the second conveyer 50. There is a pan 58 that is used to hold all Patrons 120 that are not secured (FIG. 9).

In front and rear of the fan 58, a Patron detector 39 including a light emitter 59 and a light collector 60 is provided. If the patron detector detects the patron 120, the detection signal is input into the control device 61 shown in FIG.

If the lid 17 for closing the slot 13 is opened, this is detected by the lid detector 62. The control device 61 controls the display portion 63 to indicate that the cover 17 should be closed and simultaneously activates the alarm device 64.

On the other hand, if the lid detector 62 indicates that the lid 17 for closing the slot 13 is closed, the control device 61 is a solenoid for locking the lid 17 through the drive circuit 65. Operate the locking mechanism 66 comprising a. When the solenoid is excited by the drive circuit 65, the tip of the plunger 67 is engaged in the engagement hole 68 formed in the cover 17.

Once the leader 122 is transported further inward of the film transfer chamber 4, it is conveyed upward by the third conveying device 70 (FIG. 1) and then through the opening 9 the film setting chamber ( Enter 3). Each time one leader 121 is sent out by the third carrier 70, the other leader 121 is moved one inch more inward than the film transfer chamber 4 by the second carrier 50. It is transported by

In an arrangement in which one leader 122 is transported one inch further into the film transfer chamber 4 by the leader guide drive unit 51 each time it is discharged by the third conveying device 70, a slot ( If the supply of the new reader 122 through 13) is temporarily stopped, some of the leader guides will be driven empty by the leader guide drive unit 51. Once the supply of reader 122 is resumed, this empty guide will cause a delay in processing the film. In order to solve this problem, as illustrated in FIG. 11, the reader guide drive unit 51 includes a first detector 86 and a second detector to detect the reader 122 supported by the reader guide 55. 87 is provided. These detectors are disposed in the vicinity of the first conveying device 18 and the third conveying device 70, respectively.

The first detector 86 and the second detector 87 are each provided with a rotary lever. This detector is activated when each lever is pushed down by the leader 122 supported by the leader guide 55. The detection signal is input into the control device 84.

After the supply of the reader 122 through the slot 13 is stopped and then resumed, the control unit 84 has some reader guides driven by the leader guide drive unit 51 from the detectors 86 and 87. It is detected to be emptied in accordance with the detection signal. (In order for the control unit 84 to detect that the supply of the reader has been resumed, the film feeder is operated when the supply of the reader is resumed, so that the supply resume switch suitable for informing the control unit 84 of this fact is supplied. Can be equipped.)

That is, if the reader 122 is not detected by the first detector 86 while the second detector 87 detects the reader, it will be detected that some reader guide 55 is empty.

If this is detected, the control unit 84 may move the motor 57 in the reverse direction, in which the leader guide 55 is moved to the first carrier 18 until the reader 122 is detected by the first detection 86. Will actuate drive 85.

Once the leader guide 55 carrying the reader 122 is detected by the first detector 86, the controller 84 moves the reader guide 55 into the third carrier 70 by one inch. In order to drive the motor 57 in the normal direction through the drive circuit (85). In this state, a pair of empty leader guides are positioned at the row ends of the leader guides facing the first conveying device 18.

In this state, the leader 122 is again conveyed through the slot 13 in turn. Each time one leader 122 is conveyed to the next position by the third conveying device 70, the leader 122 in the film conveying chamber 4 is conveyed one more pitch inward. In this way, the leader 122 transferred to the film setting chamber 4 after the temporary stop of the leader 122 supply is set in the leader guide which does not carry the leader due to the temporary stop of the leader supply. Thus, the film can proceed effectively to the next step without wasting time.

The number of intermittent movements of the leader guide may be calculated by the controller 84. (A sensor for detecting the leader guide 55 may be provided for counting the number of intermittent movements. The calculated number of intermittent movements may also be provided to the chamber 4 to calculate the number of empty guides. It can be used to display the number of readers that can be supplied on the display portion 63. Therefore, the supply of the reader can be effectively controlled.

In this embodiment, detectors 86 and 87 are used to detect reader 122. However, this can be used to detect patron 120. In addition, the detectors 86 and 87 may act as optical sensors to detect the reader 122 or the patron 120 without contacting them.

As shown in FIG. 1, the third conveying apparatus 70 is a toothed pulley 74 driven by a gear 73 and a gear pulley 71 and 72 provided on the upper and lower portions of the film transfer chamber 4. ), A timing belt 75 wound around the pulleys 71, 72 and 74, and a carrier 76 secured to the timing belt 75.
