Abstract

PURPOSE:To surely automatically feed a curled film or a thin long object having no rigidity by providing a film guiding member which forms a fixed film feeding path in a buffer chamber. CONSTITUTION:In the case of automatically feeding the leading edge of the long object F, the long object F is guided along the fixed feeding path L for a long substance by a long substance guiding member 11. Meanwhile, in the case of strong the long object, the member 11 is retreated from the feeding path L and the long object F is separated from the feeding path L to be stored in a loop state in the buffer chamber 8. As for the long object F ejectably fed from the buffer chamber 8 by an ejectably feeding means 10, the part thereof overlapped in the loop state is separated by a long object separating member 15 provided near the ejectably feeding means. Thus, the leading edge of the long substance F is automatically loaded without hindering the storage of the long object F in the buffer chamber 8 and the loop part of the long object F is prevented from being wound into the means 10 when it is ejectably fed.

Description

Detailed Description of the Invention (Industrial Field of Application) The present invention is applied to, for example, a film transport path of a processor camera, and is used to transport a long object such as a film or tape onto a loop during a predetermined process. This invention relates to a buffer device for storing long objects.

(Prior Art) A conventional long object buffer device of this type is provided in a processor camera as shown in FIG. 9, for example. The processor camera is a photographing device equipped with an automatic developing machine that includes a photographing section 101 for photographing subject information on a long film, and a developing section 102 for automatically developing the photographed film.

Normally, in a processor camera, a predetermined length of film photographed in the photographing section 101 is controlled to control the difference in the advance of the film F between the photographing section 101 and the developing section 102, and to prevent wasteful consumption of the film F. Film F
is temporarily stored in the buffer chamber 103 before moving on to the next development process.
A long object buffer device is used which stores the stored film F inside the film and sends out the stored film F to the developing section 102 again.

That is, the buffer chamber 103 is connected to the photographing section 101 and the developing section 1.
02, and stores the film F in a loop shape. A feeding means 104 for feeding the film F into the buffer chamber 103 and a buffer chamber 1
03 is provided, and the film F discharged from the buffer chamber 103 is cut into a desired length by a cutter 106.

(Problem to be solved by the invention) However, in the case of the above-mentioned prior art.

As the amount of film F stored in the buffer chamber 103 increases, the buffer chamber 103 will naturally be filled with the loop-shaped film F. the result,
When sending the film F from inside the buffer chamber 103 to the developing section 102 side.

There was a serious problem in that the loop portion was caught in the middle of the discharging means 105.

In addition, in order to first automatically pass the leading edge of the film F between the feeding means 104 and the discharging means 105 in the buffer chamber 103, a guide member or the like is required to guide the film F during this period. be. However, when considering that the film F is then stored in the buffer chamber 103 by only driving the feeding means 104, such a guide member becomes a hindrance. Therefore, a predetermined length of the leading edge of the film must be set by hand, which is a problem.

The present invention has been made to solve the problems of the prior art described above, and its purpose is to enable automatic loading of the leading end of a long object without interfering with the storage of the long object in the buffer chamber. At the same time, it is an object of the present invention to provide a long object buffer device that can prevent a loop portion of a long object from being caught in a discharging means during discharge.

(Means for Solving the Problems) In order to achieve the above object, the present invention includes a buffer chamber for storing long objects in a loop shape, and a feeder for feeding the long objects into the buffer chamber. and a discharging means for feeding out the elongated objects in the buffer chamber, for forming a fixed elongated object transfer path between the feeding means and the discharging means in the buffer chamber. A long object guide member is provided, the guide member can be retracted out of the long object transfer path when storing the long object, and the long object is further prevented from being caught in the vicinity of the ejection means. It is characterized by being provided with an object separation member.

The long object guide member guides one side of the long object along the long object transfer path, and is preferably capable of rotating and retracting from the long object transfer path.

The long object separation member may be rotated during storage and discharge of the long object, and may form a long object discharge port along with a guide in the buffer chamber on the upstream side of the ejection means.

It is effective that the rotation operation of the long object separation member is performed in conjunction with the retracting operation of the long object guide member.

(Function) In the long object buffer device configured as described above, when automatically feeding the leading end of a long object, the long object is guided along a fixed long object transfer path by the long object guide member. You will be guided. On the other hand, when storing a long object, by retracting the long object guide member from the long object transfer path, the long object is separated from the long object transfer path and stored in a loop shape in the buffer chamber.

Moreover, the long object discharged from the buffer chamber by the discharge means is separated from its loop-shaped overlapping portion by a long object separating member provided near the discharge means, thereby preventing entrainment.

(Example) The present invention will be explained below based on the illustrated example. 1st

A discharge roller 10 is provided at a side position facing the 8th angle, and a guide roller 13 is disposed within the buffer chamber 8 between the feed roller 9 and the discharge roller 10.

Further, within the buffer chamber 8, a film guide lever 11 is provided as a long object guide member for forming a fixed film transport path between the feed roller 9 and the discharge roller 10. The film transport path is a U-shaped path from the feed roller 9 to the discharge roller 10 via the guide roller 13, and the film guide lever 11 is U-shaped following the film transport MWL. The film F is guided in a U-shape along the inner edge. The film guide lever 11 guides one side of the film F, and in this embodiment, guides the exposed side of the film F. In addition, the film guide lever 11
is rotatably supported at its end on the feeding roller 9 side about a rotating shaft 12 as a fulcrum, and can be largely retracted from the film transport path during film storage.

As shown in FIG. 3, inside the buffer chamber 8, there are first, second, . Third guide walls 8a, 8b, 8c are formed on both side surfaces. Of these, the second guide wall 8b has a U shape that follows the film transport path.
It is formed in the shape of a letter and regulates the moving direction of the film F between the film guide /<-11.

Further, the third guide wall 8C is provided near the discharge port and faces the film separation lever 15.

The film separation lever 15 is provided in the vicinity of the delivery roller 1O, and narrows the transport path of the film F to prevent the loop portion of the film F from being caught in the delivery roller 10. In this embodiment, the film separation lever 15 is a guide roller. It is rotatably provided on a rotating shaft 14 of 13. The film separation lever 15 is a member with a triangularly pointed tip 15a, and is capable of selecting two positions: an autoloading position 1i15X and a normal film separation position 1t15Y.

FIG. 4 shows an example of a mechanism for operating the film guide lever 11 and the film separation lever 15. Around the rotating part of the film guide lever 11, there is a
A gear lla is formed integrally with -11. Further, a fan-shaped gear 20 that meshes with this gear lla is provided,
One end of this fan-shaped gear 20 is engaged with a plunger 24 of a solenoid 23 via an engagement pin 22. For this reason,
When the plunger 24 is sucked, the gear 20 rotates in the direction of the arrow in the figure using the rotation shaft 21 as a fulcrum. As a result, the gear 11a of the film guide lever 11 rotates to the 15th position!
It operates in the film loading (automatic feeding) state shown in J. A return spring 25 is connected to a part of the film guide lever 11, and when the suction force of the solenoid 23 is released, the return spring 25 moves the film guide lever 11 to the retracted position lIY shown in FIG. will be returned to.

Similarly, the film separation lever 15 is integrally formed with a gear 15a around the rotating shaft 15. A fan-shaped gear 20 that meshes with the gear 15a, and a plunger 24 and a solenoid 23' that are engaged with one end of the fan-shaped gear 20 via an engagement pin 22 are provided. When the solenoid 23' magnetically attracts the plunger 24, the gear 20 rotates in the direction of the arrow in the figure using the rotation shaft 21 as a fulcrum. As a result, the film separation lever 15
By rotating the gear portion 15a.

It operates to the separation position 15Y shown in FIG. Also, gear 2
A return spring 26 is connected to a portion of the lever 15, and when the suction force of the solenoid 23' is released, the return spring 26 sets the lever 15 to the autoloading position 15X shown in FIG.

Note that 17 is a cutter for cutting the film, which is disposed between the delivery roller 1O and the developing section 18, and a sensor 16 for film detection is provided between the cutter 17 and the delivery roller 1O.

Next, the operation of the long object buffer device having the above configuration will be explained. The state of the buffer chamber 8 in FIG. 1 shows the state at the time of initial loading. A film F fed by a supply roller 4 in the photographing section 1 is guided into a buffer chamber 8 and is conveyed between a feed roller 9 and a discharge roller 10 while being guided by a film guide /<-11.

At this time, the film separation lever 15 is at the autoloading position 15X so as not to interfere with the conveyance of the film F. The film F that has passed through the delivery roller IO and exited the buffer chamber 8 is sent to the developing section 18 by a sensor 16.
detects the leading edge of the film F, the rotation of the roller 10 is stopped, and the film F is temporarily stopped at this position. That is,
At this time, the leading end of the film F is held by the delivery roller 10.

Thereafter, as shown in FIG. 2, only the feeding roller 9 rotates and the film F is stored in the buffer chamber 8. At this time, the film guide lever 11 rotates around the rotation shaft 12 to the retracted position 1111Y so as not to interfere with the storage of the film F. Also.

The film separation lever 15 rotates to a separation position 15Y using the rotation shaft 14 of the guide roller 13 as a fulcrum.

When discharging the film F from the buffer chamber 8, the discharging roller 10 rotates, but at this time, as shown in FIG. is restricting the outlet. For this reason, the film F stored in a loop in the buffer chamber 8 is separated at the discharge port 8d, and may fold over or become untransportable (jam ), and the photographed film F
In particular, in this embodiment, the film separation lever 15 at the separation position 15Y and the third guide wall 8C are made straight at the opening of the discharge port 8d to enhance the effect of preventing the film from being caught. There is.

It is preferable to use a drive solenoid 23' for the film separation lever 15 shown in FIG. 4 that is equipped with a permanent magnet inside. Plunger 24 by permanent magnet
Therefore, the film separation lever 15 can be maintained at the separation position shown in FIG. For this reason,
While the film F' is stored in the buffer chamber 8,
Since no holding power is required when the device is left in the stored state for a long time, no wasted power is consumed, and the device can be maintained in the same position even if the power to the entire device is turned off.

On the other hand, after ejecting and rinsing the stored film F', move the film separation lever 15 to the autoloading position! 15A
When returning to
It can be restored by applying a voltage to .

The timing to return the film separation lever 15 is preferably just before the film F' stored inside the buffer chamber 8 is discharged and the loop disappears. After being fed, the film F may be separated by stretching between the guide roller 13 and the discharge roller 10, and the film 8-15 may be returned.

In the above embodiment, the length of the film F in the buffer chamber 8 is counted by encoders 9A and IOA provided on the respective roller shafts of the feeding roller 9 and the discharging roller 10 as shown in FIG. Photo interrupter 9B, IOB
It is calculated by counting the number of pulses.

Next, B (JJJ indicates the time of buffer storage of the film F. By driving the feeding roller 9, the film F is fed into the buffer chamber 8. The buffer chamber 8
The feed amount of the film F fed into the feed roller 9 is calculated by detecting the number of pulses proportional to the amount of rotation of the feed roller 9 by an encoder 9A provided on the roller shaft of the feed roller 9. At this time, a certain amount of film F is stored in the buffer chamber 8, and when a loop is formed in the film F (between Ba), the film separation lever solenoid 23' is driven and the state shown in FIG. 2 is achieved.

The 0 point is the FULL state in the buffer chamber 8 or the point at which development has started, and the feeding roller 9 has stopped and the discharging roller 10 has stopped.

This shows the time when the film F is being discharged from the buffer.

The discharge i of the film F discharged from the buffer chamber 8 is
It is calculated by detecting the number of pulses proportional to the amount of rotation of the delivery roller 10 using an encoder 10A provided on the delivery roller 10 axis.

Point D: C/<-/This is the point where the film F in the film chamber 8 is fully discharged and the buffer amount becomes zero. The film separation lever 15 returns to the state shown in FIG. 1 before the buffer reaches zero (point b) by comparing the buffer supply amount with the buffer discharge amount. At this point D, the film loop in the buffer chamber 8 disappears, so the film F transported by the discharge roller 10 is supplied, the feed roller 9 rotates together, and the encoder 9 of the feed roller 9 is again rotated.
A pulse signal is generated from A. Thereafter, after the final exposure image on the film F located at the exposure position on the photographing roller 6 is fed to a position where it passes the cutter 17 (point E), the film cutter driving slide/id 17A is activated to
is disconnected. Thereafter, the operations B-H are repeated.

FIG. 8 shows another embodiment of the present invention, and in order to simplify the explanation, only the differences from the previous embodiment will be explained.

Whereas in the previous embodiment, the film guide 8-11 and the film separation lever 15 were operated independently by separate drive sources, in this embodiment, the film guide 8-11 and the film separation lever 15 were operated independently by separate drive sources.
11 and film separation lever 15 are moved in conjunction with each other by the same driving source.

Since the other configurations are the same as those of the previous embodiment, the same components are given the same reference numerals and the explanation thereof will be omitted.
