Abstract

PURPOSE:To make it possible to fix a failure in its early stage, by providing such an arrangement that a mechanism associated with a failure position may be actuated by depressinga normal switch. CONSTITUTION:A film is loaded onto a cassette C from one of supply magazines SM1 through SM3 which store unused films, and a processed film is retrieved from the cassette C and transferred to a receiver magazine RM. When any trouble occurs during loading and retrieving of this film, the failure position is indicated by its corresponding number on a trouble displaying unit on which reference codes are provided, in a control and display section A on the front surface of a center chamber 2, and therefore, the failure position is at once known by this number so that a mechanism or part which fails, is predicted. Then, the number of the predicted mechanism or part is designated by means of a repeat switch or the like through the trouble displaying unit, and a supply-alone-switch (c) is turned on to actuate the designated mechanism or part. Therefore, if the mechanism or part of the designated number is abnormal, it is found that this mechanism or part causes the failure to occur.

Description

DETAILED DESCRIPTION OF THE INVENTION ■ Industrial Application Field The present invention involves loading a film into a cassette from a supply magazine containing unused films, collecting the processed film from the power center, and carrying it into a receive magazine. Regarding film loading/recovery equipment.

2. Prior Art First, the outline of the film loading/recovering device will be explained.

The film loading/recovering device is divided into three rooms, and the bottom room is equipped with a supply magazine containing a large number of unused films.

We have multiple Zabli magazines available for each film size.
There are also devices installed here. When the supply magazine is installed here, the lid of the Xabry magazine is opened, and a sheet of film is taken out by a known suction cup mechanism, transported to a predetermined position, and waited there.

On the other hand, when a cassette loaded with photographed film is inserted into the central room, the lid of the cassette is opened, and the photographed film is collected by the same suction cup mechanism as described above and placed in the bottom room. It is transported to the set receive magazine. Then, the empty cassette is loaded with unused film waiting in the bottom room, and the lid is locked. The cassette loaded with unused film is ejected outside and reinserted into the central room after shooting. Here, the film is collected.

When an appropriate number of sheets have been carried into the receive magazine, they are all processed for development. This device repeats the above operations each time a cassette loaded with film that has been shot is inserted.

After many shots have been taken and unused film is loaded into the cassette from the supply magazine, when there is no more film in the supply magazine, take it out and put the unused film in the ZaBry magazine. Once attached to the device, the film can be loaded and recovered by the above-described operations again.

In this film loading/recovering device, a very thin film is loaded into a cassette from a supply magazine, and the photographed film is collected from the cassette and loaded into a receive magazine. Failures are likely to occur during film transport, and when loading film into a cassette, unlock the cassette lid, lift the lid to a position where it does not interfere with film collection and loading, collect the film, and then The timing of each mechanism's operation, such as loading, is also limited. In order to transport the film smoothly, a large number of rolls are required, and in order to rotate these rolls, the number of motors must be increased in proportion to the number of rolls. Also, to limit the timing at which each mechanism operates,
Requires many microswitches and sensors.

That is, this film loading/recovering device is a complicated and delicate device that requires a large number of parts. If the number of parts used is large, complex, and delicate, it is difficult to find the location of the trouble (failure) once a problem occurs.

Therefore, when a failure occurs in this device, it is necessary to take measures to eliminate the problem. In order to quickly eliminate trouble and restore normal operation, it is necessary to discover the failure location as soon as possible and replace any defective parts.

Conventionally, the internal structure of the film loading/recovering device was relatively simple, and in some cases, a detector was installed at each location1, and when normal operation was not performed, this detector detected and this message was displayed on the display. It was displaying. Therefore, the location of the failure can be easily determined by the display on the display, making it possible to shorten the time it takes to discover the failure location.

However, as mentioned above, this film loading/recovering device has a large number of parts and is extremely complex and delicate in structure, so even if the location of the failure is identified, it is difficult to determine which part (
For example, it is not possible to clearly determine whether the failure is caused by the microswitch or motor.

For example, if this malfunction is displayed on the display when loading an unused film into the cassette, it may be that the film is not actually loaded in the cassette, or even if the film is loaded in the cassette. It is unclear whether this detection unit does not detect it or whether there is another cause. In order to quickly eliminate a problem, it is not enough to simply know where the problem is.

3. Purpose of the Invention As a result of considering the above, the present inventor has devised a technology that, when a failure occurs, displays the location of the failure and detects the component that is the cause of the failure. 4. The invention That is, in the present invention, the film is loaded from a supply magazine containing unused film into a cart,
A film loading/recovering device that collects processed film from the cassette and transports it into a receive magazine has a mechanism that operates a drive operation switch of a drive mechanism of each process to detect the operable state of each process. The present invention relates to a film loading/recovering device characterized by:

5. Examples Hereinafter, the present invention will be explained in detail with reference to examples shown in the drawings.

FIG. F is a schematic diagram of a film loading and retrieving apparatus incorporating the configuration of the present invention.

The supplied supply magazine SM is installed. In FIG. 1, three types of supply magazines SM1 to SMs storing films of different sizes are installed in the mounting section CH1.

It shows that it is attached to CH2 and CH5.

In room 2, insert an unused film into cassette C,
This is a room set up to take out photos from the cassettes and LCs that have already been photographed. - In the upper room 3, the photographed film taken out from the cassette C is sent to the receive magazine RM.
It is provided for insertion into.

Next, the operation of this device will be explained. For example, when the Zabre Magazine SM+ is installed in the room 1 of this device, the shutter 4 of the supply magazine S 114 opens,
One sheet of film stored in the supply magazine S Ml is sucked by a suction cup 5 and conveyed to a place where it is held between rollers 6 . The film held between the rollers 6 is conveyed by the rotation of the rollers 6 and presses the microswivel notch S. The rotation of the roller 6 is stopped by actuation of the microswitch S1, and the film is placed in a standby state.

1. When a cassette is inserted into the central chamber 2, a detector MS provided under the cassette receiving plate 18 detects the size of the cassette and outputs this signal to the supply section 1. When the film size of the supply magazine S Ml is selected by this signal, the film waiting between the rollers 6 and 7 is transported by the rotation of the rollers 7.8 and 9.10, and the microswitch S2 is activated. Press and wait at this location until the lid of cassette C is opened. The reason why the film is transported to the location where the microswitch St is located before the cassette lid is opened is to shorten the time required to load the film into the cassette C as much as possible.

When the lid of the cassette C is opened, the roller IL12 rotates and the film is loaded into the cassette C.

When the film is loaded into the cassette C, the lid of the cassette C is closed and the cassette C is ejected to the outside, so that the cassette C can be used for photographing. After taking a picture and inserting the cassette C into the chamber 2 of this device again, the lid of the cassette +-C is opened and the film that has been shot is taken out from the ZaBry Magazine SMj and transported by the same mechanism. , and is transported to the room above this room 2 where the receive magazine RM is installed, and inserted into the receive magazine RM.

The cassette C from which the photographed film has been taken out is again loaded with unused film and photographed.

While photographing is being performed, this device repeats the above operations, and a number of photographed films are inserted into the receive magazine RM. When you have reached the appropriate number of sheets, you can take them out and develop them.

Next, the opening/closing mechanism of the lid of the cassette C will be explained in detail.

FIG. 2 is a diagram showing a cassette C used in this film loading/recovering device. The base plate 13 is provided with a catch 16 for keeping the lid 14 closed and a release fitting 15 for releasing it. A claw 17 is provided.

3 to 7 are side views showing the operating state of the opening/closing mechanism of the lid 14 of the cassette C when the cassette C containing photographed film is mounted on the cassette receiving plate 18. Several crimping levers 20 are provided on one piece of the cassette receiving plate 18, one of which is attached to an eccentric position of the cam 19.
As the cam 19 rotates, one of the cassettes C moves up and down. For example, as shown in FIG.
9 is rotated in the direction of the arrow, one piece of the cassette C is pushed up by the crimp lever 20, and the release mold 21 provided on the cassette guide plate (not shown) releases the cassette C.
It engages with the groove 22 provided on the release fitting 15. The release mold 21 is attached to the cassette guide plate via a spring 23, but the spring 23 does not have enough force to open the lid 14 of the cassette C, and only semi-fixes the cassette C. When the cam 19 continues to rotate in the direction of the arrow, the release lever 2 attached to the eccentric position of the cam 19
4 presses the release claw 21.

do. The cassette C is pushed up by the crimp lever 20,
On the other hand, since the release claw 21 is pressed by one piece 25 of the release lever 24, the release claw 21 is pressed by the release fitting 15 of the cassette l-C.
, the claw 17 of the cassette C is released from the clasp 16, and M14 is opened. FIG. 5 shows this state. The lid 14 of the opened cassette C is lifted by the lid suction mechanism 30 shown in FIG. 1 to a position where it does not interfere with the insertion and removal of the film.

Here, the photographed film is removed from the cassette C, and an unused film is inserted. Cassette C is tilted as shown in FIG. 6 to ensure that the film is loaded in the correct position. In addition, the spring 2 attached to the crimping lever 20 is provided to absorb excessive force when it is applied to the cassette holder Fj, 18, etc. due to the operation of the crimping lever 20. ing.

Next, the case of closing the lid 14 of the cassette C will be explained.

When one film is loaded into the cassette C, the cam 19 is rotated counterclockwise to place the cassette receiving plate 18 in a horizontal position. Here, when the cam 27 with one end of the release lever 24 removed rotates in the direction of the arrow as shown in FIG. 6, the release lever 24 swings about the support shaft P.
A pressure roller 28 tilted in the direction of the arrow and attached to the release lever 24 is located above the lid 14 of the cassette C. Then, as shown in FIG. 6, when the cam 19 rotates clockwise again, the crimp lever? 0 pushes up the cassette receiving plate 18, the lid 14 of the cassette C is pressed against the substrate 13 of the cassette C by the pressure roller 28, and the lid 14 is closed. FIG. 7 shows this state.

At this position, the rotation of the cam 19 is stopped and the pushing up of the cassette receiving plate 18 is stopped. Then, the cam 19 is rotated counterclockwise to return the cassette C to the horizontal position, and the cam 27
By rotating , the pressure roller 28 is moved from above the cassette C.

At this point, one cycle is completed by taking out the cassette L-C and reinstalling the cassette C into the apparatus after photographing.

In addition to displaying the film loading/recovery bag constructed as described above, the bag is equipped with a curved groove that allows the status of each load to be concretely checked using this display.

Next, this check mechanism and its effects will be explained in detail.

FIG. 8 is a partial view of the operation/display section A provided at the front of the room 2 in the center of FIG. The portions of the operation/display section that are marked with symbols from A to POWER are switches for performing the operations described below. For example, if you press a switch with a force display,
The power to this device can be turned on and off, and by pressing one switch, only the film can be loaded into the cassette.

The parts marked with symbols K to F are display parts that light up when an item to be prepared for photographing is attached to this device. For example, if C is lit, it means that the receive magazine RC is installed in room 3, and if C is lit, the supply magazine containing the film in section 4 is installed in the loading section CH<. It shows that it is installed.

The trouble display with the symbol "A" is, for example, a digital display that displays a two-digit number, and if a trouble occurs while the device is operating, the detector will detect it. , the location of the malfunction is displayed using a two-digit number. When a failure occurs, you can immediately find out where the problem is occurring from the displayed numbers.

If you know where the failure is occurring, you can predict to some extent what is causing the failure.

Therefore, the trouble check mechanism is activated and the search for defective parts begins. To achieve this state, for example, a switch is provided, and when the check mechanism is to be activated, turning on this switch causes the sequence to perform the work of the check mechanism instead of functioning as a film loading/recovering device. .

This operation will be explained below.

The output of the microcomputer is connected to the suction cup mechanism, motor, etc. of this film loading/recovering device, and when a numerical address is given to the microcomputer, the designated suction cup mechanism, motor, etc. is operated.

And to address the microcomputer,
This is determined by the number displayed on the trouble display. A random number table is predetermined, such as specifying a number to activate which motor.If this number is displayed on the trouble display, this decimal number is converted to a binary number, and the converted binary number is used to control the microcomputer. If the ROM or RAM is addressed, the mechanism or motor corresponding to the number indicated in the random number table will operate. Figure 8 shows the random number table used in this embodiment.

Next, the operation for addressing the ROM etc. of the microcomputer will be explained. The trouble display can display a two-digit number, with the left digit used to designate a certain unit. For example, if you want to operate a certain mechanism in the supply section 1 of the supply magazine SM, first specify that it is the supply section 1 using the digit on the left, and then specify which mechanism in the supply section 1 using the digit with YES. It specifies whether the mechanism should be operated. In this example,
The number on the left can be specified by pressing the repeat switch "A" and the receive subry switch "O". The number obtained by adding 1 to the number will be displayed, and when you press the receive subry switch °゛o'', the number obtained by subtracting 1 from the displayed number will be displayed.You can also change the number by using one switch. For example, if the initial display is 7 and the number you want to specify is 6, you will have to press the repeat switch 9 times, which takes time and effort. can now be specified.

The number on the right side of the trouble display can also be specified by buzzer power, toggle switch "A", and "receive only switch fly".

After the number of the mechanism to be operated is displayed on the trouble display, turn on the supply switch "TSU" to operate it, and turn OFF the supply switch "TSU" to stop it. It is said that

At this time, if the operating mechanism involves the on/off operation of a detector such as a microswitch, this will be lit on the display section.

If a problem occurs while operating the device, the location of the problem will be indicated by a number on the trouble display.

Using this number, you can immediately find out where the failure is occurring, and you can predict to some extent which mechanism or part is failing. Then, using the random number table shown in FIG. 9, the number of the predicted mechanism or part is designated by repeat switch "a" or the like by displaying the trouble. And supply only switch “
If you turn on ", the mechanism with the specified number becomes operational. You can check the operational status by removing the side cover of the film loading/recovering device and checking visually. In other words, if there is a malfunction. By independently operating and checking the predicted mechanism, if there is no abnormality in its operation (i.e., if it operates normally), it will be determined that there is another cause, and if there is an abnormality in its operation, (i.e., it will stop, etc.) If the device is in an abnormal state), it can be determined that the failure occurred due to its mechanism or parts.The operating state of the detector, such as a microswitch, can also be checked from the beginning to the end of the display. Since this can be confirmed by the indicator lamp, it is possible to determine whether the mechanism itself is malfunctioning or whether the microswitch that detects this is malfunctioning.

Above, we have explained the case of checking the operating status of a malfunctioning mechanism or parts when a trouble occurs during operation, but the present invention can
Of course, this method can also be applied to confirming the operating state. For example, in the manufacturing process, if a mechanism or part is attached to this device and the operation is confirmed before proceeding with the work, it will be easier to inspect the finished product. Similar inspection work can be performed even after the product is completed.

FIG. 10 shows a flowchart of the above operation.

6. Effects of the Invention Many of the people who load and retrieve films using this device are not mechanical or electrical experts, and those who repair when a failure occurs are service personnel.

In the case of multiple systems, when a malfunction occurs, a phone call is made, and the service engineer predicts the malfunctioning mechanism based on the content of the call, prepares the necessary parts, and heads to the site. If the cause of the failure is specific, preparations can be made accordingly.

In the past, service personnel could only know the general location of the malfunction, and even if they went to the site, they were sometimes unable to eliminate the malfunction with the parts they had prepared.

However, as shown in the present invention, if the mechanism related to the location where the failure occurs can be made operational by pressing the appropriate switch, and this can be checked. This can be done under the direction of a service person over the phone, or independently. When requesting repair, it is possible to not only notify the location of the failure, but also the mechanism or part that is causing the failure. Therefore, service personnel can clearly understand the cause of the failure, prepare parts, and then head to the site. This eliminates the waste of having to go to the site again, which simplifies maintenance. Ta.

In addition, in the manufacturing process of this device, if you check the operation of the installed mechanisms and parts before starting the next work, you can check the work process while doing it, and it is also necessary for checking the operation after the device is completed. It is possible to shorten the time required for That is, it is possible to reduce errors in the manufacturing process of this device and shorten the time required for completion.
