Description

Description: TECHNICAL FIELD The present invention relates to a sheet film loading method for selectively taking out a sheet film from a plurality of magazines and loading the film into a cassette.

[Conventional technology]

As an apparatus for loading an X-ray film into a cassette for imaging, an X-ray sheet film is divided into different types and accommodated in a plurality of magazines, and the extracting means and these magazines selectively correspond to each other. A loading device is used in which the end of a film in a magazine is taken out by suction of a take-out means, and is loaded into a cassette (Japanese Patent Laid-Open Nos. 62-249833 and 63-228142).

In these sheet film loading devices, magazines are arranged in multiple stages up and down, and in a standby state, a specific magazine among the magazines in multiple stages and the unloading means correspond to corresponding positions,
As an example, the position where the unloading means corresponds to the lowermost magazine is in the ready state, and is ready for the next film unloading.
Here, when the cassette is inserted, a magazine containing a film corresponding to the type of the cassette is selected,
The magazine or the take-out means moves up and down, and the take-out means corresponds to the selected magazine, and the sheet film in the magazine is taken out and loaded into the cassette. After the sheet film has been loaded into the cassette, the unloading means and the magazine return to the specific position again, and are ready for the next sheet film loading.

Therefore, in such a sheet film loading apparatus, in the preparation state, when the sheet film is continuously taken out from a magazine different from the corresponding magazine in the preparatory state, the sheet taking out means and the magazine must be taken out during this continuous unloading state. Must be relatively moved to a specific position, which hinders quick removal.

[Object of the invention]

The present invention has been made in consideration of the above-described circumstances, and has as its object to provide a sheet film loading method capable of quickly loading a sheet film into a cassette when the same type of sheet film is continuously taken out.

[Means for solving the problem]

The present invention is a sheet film loading method for taking out a sheet film by adjoining one of a plurality of magazines accommodating the sheet film with a film take-out means, transporting the sheet film to a cassette by the film take-out means, and loading the film. The number of times the sheet film is taken out from the magazine using the film taking out means is integrated for each magazine, and the film taking out means is made to stand by at a position adjacent to the magazine having the largest integrated value.

In the present invention having the above-described structure, the film take-out means is made to stand by next to the magazine accommodating the sheet film having the largest number of take-out times (frequent take-out frequency).
When the sheet film is taken out of the magazine in which the sheet film that has been taken out frequently is stored, the relative movement between the magazine and the film taking out means becomes unnecessary, and the work of taking out the sheet film can be performed quickly.

If a sheet film accommodated in a magazine different from the magazine accommodating the sheet film of which the number of times of removal is large is selected, the film unloading means is relatively moved to the magazine accommodating the selected sheet film. However, since the relative movement occurs less frequently, the time required to take out the sheet film is shortened as a whole. The magazine in which the most frequently taken out sheet film is stored in the predetermined period can be determined by integrating the number of times of taking out each sheet film selected in the predetermined period by the counter, and comparing the integrated value for each magazine. .

When a plurality of magazines and the film take-out means are adjacent to each other, the film take-out means may be moved so as to be adjacent to any one of the plurality of magazines. Any one of them may be adjacent to the film take-out means.

Further, in the present invention, in addition to the case where the film taking-out means directly loads the sheet film into the cassette after the film taking-out means takes out the sheet film from the magazine, the taken-out sheet film is delivered to and held by the holding means. The holding means moves to a position adjacent to the cassette while holding the sheet film, or
Alternatively, the sheet film may be transported, and the sheet film may be loaded into the cassette.

As shown in FIG. 2, a pair of elevating frames 42 are fixed to the holding means 16 in parallel with each other by a plurality of connecting rods 44, and the sheet film F is held between the elevating frames 42. ing.

Guide block 46 fixed to the outside of the lifting frame 42
A guide shaft 48 whose axis is vertical and whose upper and lower ends are fixed to the frame 11 penetrates. A screw shaft 52 is screwed into a similar guide block 47 to one of the lifting frames 42, and the screw shaft 52 is arranged in parallel with the guide shaft 48. Therefore, when the screw shaft 52 rotates by receiving the driving force of the pulse motor 54 or the like, the lifting frame 42 moves up and down to a predetermined position and
12 and cassette 18 can be supported. The drive and stop of the pulse motor 54 are controlled by the control device 130.

A pair of entrance holding rollers 82 are vertically supported near the lower end of the lifting frame 42 in parallel with each other. These entrance holding rollers 82 are for receiving the sheet film F taken out of the magazine 12 by the suction cup 136 and feeding it in the direction of arrow E to bend and hold the sheet film F in a substantially semicircular shape. A pair of intermediate holding rollers 84 and a pair of intermediate holding rollers 86 are pivotally supported in the same manner as the entrance holding roller 82, corresponding to the intermediate portion of the sheet film F held in a semicircular shape. Further, a pair of outlet holding rollers 88 for holding the leading end of the sheet film F held in a semicircular shape is provided. Therefore, in the holding state of the long-sized sheet film F, the rear end of the sheet film F is held by the inlet holding rollers 82, the middle part is held by the middle holding rollers 84 and 86, and the leading end is held by the outlet holding rollers 88. Will be. Even when the size of the sheet film F is short, the leading end must be an exit holding roller.
It is held at 88.

The outlet holding roller 88 is supported by the lifting frame 42 near the tip of a tilting frame 94 which is supported by a shaft 92.

Another part of the endless belt 104 is wound around a pulley 108 fixed to an elevating frame 42 and fixed to an output shaft of a pulse motor 106 controlled by a controller 130.

Therefore, when the pulse motor 106 rotates, the second swing link 99 rotates together with the rotating shaft 100, and the first swing link 97 receives this rotational force to move the tilting frame 94 in the counterclockwise direction (the direction of arrow G) as shown in FIG. ). As a result, the sheet film F is moved above the entrance of the cassette 18 with its leading end portion being clamped by the exit clamping roller 88, so that the sheet film F can be easily inserted into the cassette 18.

2, a pulley 114 and an endless timing belt 116 for transmitting the driving force of the pulse motor 112 to the entrance clamping roller 82, the intermediate clamping rollers 84, 86 and the exit clamping roller 88 are provided outside the lifting frame 42. Several are used. This pulse motor 112 is driven by the control device 130,
Stopping is controlled.

FIG. 4 is a schematic block diagram of the control device 130. The control device 130 includes a CPU 158, a RAM 160, a ROM 162, an input port 164, and an output port 166. The input port 164 is connected to a film type identification sensor 168 and a keyboard 131. In the present embodiment, a magazine selection method for associating the unloading means 14 and the holding means 16 is divided into a manual mode, a calculation mode, and a previous mode.
There are different modes. The manual mode always selects the magazine with the film specified by the keyboard 131, the calculation mode calculates the frequency and selects the magazine with the most frequently extracted film within a predetermined period. Select the magazine from which the sheet film was removed. Since the frequently used sheet film is likely to be continuously taken out, in the previous mode, after the previous sheet film is taken out, it is set to the ready state corresponding to the previously selected magazine, so that it can be taken out at the next time. Sheet films that are frequently used can be selected. Because of this, the keyboard
131 is provided with keys for selecting these three modes and keys for inputting data. Output port 166
Have pulse motors 129, 54, 68, 146, 148, 112 and
106 is connected.

Next, the operation of this embodiment will be described with reference to the flowcharts of FIGS. 5 (A) and 5 (B).

First, the operator selects a mode suitable for the work content from the keyboard 131 among the three types of magazine selection modes. For example, if there is a possibility that the number and order of multiple types of films may be used at random, select the calculation mode.If you mainly use a single film and occasionally use other films, select the manual mode. When a mode is selected and a plurality of types of films are used sequentially in a plurality of times, the previous mode is selected. The mode and data input from the keyboard 131 are stored in the RAM 160.
The contents of the RAM 160 are rewritten each time the mode is switched.

In step 200, the input from the keyboard 131 and the RA
The mode stored in M160 is read. Subsequently, in step 202, it is determined whether or not the stored mode is the manual mode. If the mode is the manual mode, the process proceeds to step 204. In the manual mode, when selecting a magazine, data of a film type and a size are required. For this reason, the operator selects the manual mode by key operation and then inputs these data and stores them in the RAM. In step 204, these data are read out, and the magazine number corresponding to the magazine in which the corresponding sheet film F is stored is determined. This magazine number is determined in advance for each of the magazines 12 and stored in the ROM, and the operator stores a sheet film corresponding to the magazine number in each magazine. After storing the film in the magazine, the magazine number may be determined so as to correspond to the film and stored in the RAM. At step 206, it is determined whether the data stored in the RAM is the data of the initial input or the data changed from the previous input data. That is, when the operator operates the sheet film loading device,
Turn on the power of 10 and select the manual mode and then enter the data entered first or the sheet film loading device.
It is determined whether or not the operator has changed the data previously input while driving 10 in the manual mode. If the determination in step 206 is affirmative, the magazine number is stored in step 208 (updated if there is a previously stored magazine number). If the determination in step 206 is denied, step 208 is not executed and the magazine number is not executed. Is not updated.

If it is determined in step 202 that the operation mode is the operation mode or the previous mode, the magazine number stored in step 210 is read. Immediately after the power of the sheet film loading device 10 is turned on, that is, in a state where the sheet film is not loaded at all, the magazine numbers of the calculation mode and the previous mode are not stored. Read the number. After the sheet film is loaded once, the magazine number specified according to each mode is read.

Next, at step 212, the take-out means 14 and the holding means 16 are moved so as to correspond to the magazine corresponding to the magazine number.
This movement is performed when the screw shaft 52 for guiding the lifting frame 42 and the screw shaft 132 for guiding the lifting frame 122 are in the pulse mode 54,
The rotation is performed by receiving the driving force of 129, so that the lifting frame 42 and the lifting frame 122 move up and down.

As described above, the sheet film loading apparatus 10 is ready to take out the film.

Step 214 loads the sheet film. A detailed routine of this loading will be described later.

After the sheet film F is loaded, the flow shifts to step 216 to determine the mode. In the case of the manual mode, the process directly proceeds to step 226. Step 2 for the calculation mode
The process proceeds to 18 to count up the number of times of use of the counter corresponding to the magazine used this time among the counters for counting the number of uses prepared for each magazine. Next, at step 220, the magazine containing the most frequently taken out film is determined by judging which magazine has the largest number of uses within a predetermined time, and at step 222 the magazine number is stored in the RAM. Step 216
If it is determined in step 224 that the mode is the previous mode, the magazine number of the magazine used this time is stored in the RAM in step 224.

At step 226, it is determined whether or not the processing has been completed. If the sheet film loading operation has been completed, this routine ends, and if the operation has not been completed, step 200 is executed again.

If the mode is changed during the operation, the mode stored in the RAM is changed. Therefore, the mode changed in step 200 is read and the processing is changed.

Next, the details of the sheet film loading routine in step 214 will be described with reference to FIG. 5B. Note that the number of pulses for driving each pulse motor is predetermined.

If it is determined in step 228 that the cassette 18 containing the photographed sheet film F is to be loaded into the sheet film loading apparatus 10 from the loading port 10A in the direction of arrow A,
In step 230, the cassette driving mechanism 20 is operated. Since the cassette drive mechanism 20 presses the cassette 18 against the cover opening pin 24, the cover plate 18B is opened as shown in FIGS.

Next, at step 232, the extracting means 26 is operated. As a result, the suction cup 28 of the take-out means 26 sucks and takes out the sheet film F in the cassette main body 18A and delivers it to the transport roller 32, so that the photographed sheet film F is sent to the developing device 34 and developed. Is performed.

In the next step 234, the film type attached to the cassette 18 is identified and the magazine number is determined.

In step 236, the magazine number determined in step 234 is compared with the magazine number of the magazine currently supported by the unloading unit 14 and the holding unit 16, and whether the unloading unit 14 and the holding unit 16 need to be moved is determined. Is determined.

If the magazine numbers match, there is no need to move the take-out means 14 and the holding means 16, and the process proceeds to step 244. If the magazine numbers do not match, step 238 is executed because the unloading means and the holding means 16 need to be moved from the magazine currently supported. In step 238, the relative distance between the magazine corresponding to the loaded cassette 18 and the magazine currently supported by the unloading means 14 and the holding means 16 is calculated by the number of pulses. In step 240, the pulse motors 129 and 54 are driven, and the take-out means 14 and the holding means 16 are moved so as to correspond to the magazine corresponding to the loaded cassette 18, and in step 242 the magazine numbers are stored.

When the take-out means 14 and the holding means 16 are positioned beside the magazine corresponding to the loaded cassette 18, in step 244, the pulse motor 68 is rotated to rotate the endless timing belt 66 clockwise in FIG. This allows the drawer pin 72
Engages with the engagement arm 74 to move the movable table 36 from the standby position of the magazine 12 to the film unloading position. With the movement of the magazine 12, the arm 12D of the slide cover 12C comes into contact with the suction piece 76, so that the slide cover 12C enters below the cover plate 12A and the take-out opening 12B is opened.

In the next step 246, the pulse motors 146 and 148 are rotated. As a result, the suction cup 136 is pressed against the uppermost sheet film F in the magazine 12. At the same time sucker 13
The negative pressure of a negative pressure source (not shown) is transmitted to 6, and the vicinity of the leading end of the sheet film F is sucked. Thereafter, the suction cup 136 is raised by the rotation of the pulse motors 146 and 148, lifted up from the take-out opening 12B, and inserts the sheet film F between the entrance holding rollers 82. Next step
At 248, the pulse motor 112 is rotated to feed the leading end of the sheet film F in the direction of arrow E, and the supply of negative pressure to the suction cup 136 is stopped. Therefore, the front end of the sheet film F passes from the entrance clamping roller 82 to the intermediate clamping roller 86 through the intermediate clamping rollers 84 and 86, and is curved in an arc shape with the distal end clamped by the exit clamping roller 88. Is held. In order for the sheet film F to move smoothly between these rollers, a guide plate 89 is provided inside the elevating frame 42.
(Shown in phantom lines in FIG. 1).

When the sheet film F is stored in the holding means 16, the suction cup 136 is returned to the reference position again in step 250, the pulse motor 68 is reversed, and the movable base 36 returns the magazine 12 to the standby position.

In the next step 252, the pulse motor 54 is driven.
As a result, the holding means 16 is raised by the rotation of the screw shaft 52, and the rising of the holding means 16 is stopped in response to the exit pinching roller 88 corresponding to the entrance of the cassette 18. In step 254, the pulse motor 106 is rotated to rotate the tilting frame 94 in the counterclockwise direction (the direction of arrow G) as shown in FIG.
The 88 is passed over the cover pin 24 and close to the vicinity of the entrance of the cassette 18. As a result, the leading end of the sheet film F is securely accommodated in the cassette 18 by the rotation of the exit pinching roller 88. As described above, since the tilting frame 94 moves the exit holding roller 88 closer to the entrance of the cassette 18, the cover opening pin 24 for opening the cover plate 18B of the cassette 18 is located in front of the cassette 18. However, the sheet film F can be reliably loaded into the cassette 18 from the holding means 16.

When the sheet film F loaded in the cassette 18 passes through the holding means 16, the front and back are reversed.
The state of being housed inside is inverted. That is, the emulsion side of the sheet film F is inserted into the cassette 18 with a cover plate.
Since the film needs to be loaded toward 18B, in a film having an emulsion surface on only one side, this emulsion surface is accommodated downward in the magazine 12. Therefore, the sucker 136 of the take-out means 14 absorbs the anti-emulsion surface so that even a sensitive film can eliminate the influence on the photographic performance due to the suction force.

Even when the tilting frame 94 rotates counterclockwise in FIG. 1 to bring the leading end of the sheet film F closer to the cassette 18, the middle and rear ends of the sheet film F are held at the entrance holding rollers 82 and the middle. A one-way clutch is provided between the entrance clamping roller 82, the intermediate clamping rollers 84, 86 and the pulley on which the timing belt 116 is wound to prevent the sheet film F from being unnecessarily tensioned by the clamping rollers 84, 86. When high-speed rotation is transmitted in the sheet film transport direction with the respective 156 interposed, it is preferable to rotate freely.

When the loading of the sheet film F into the cassette 18 is completed, the pulse motor 106 is driven in step 256, and the tilting frame 94 is returned to the vertical position again. Finally step 258
Then, the cassette drive mechanism is operated, the cassette 18 is discharged from the loading port 10A of the sheet film loading device 10, and the loading of the sheet film is completed.

Therefore, the next cassette 18 is used for the sheet film loading device 10.
If the sheet film F to be loaded into the cassette 18 is the most frequently used film, the unloading means 14 and the holding means 16 do not move up and down, and the sheet is immediately removed from the uppermost magazine 12. The film F can be taken out and a quick loading operation can be performed.

〔The invention's effect〕

Since the present invention is configured as described above, it has an excellent effect that a frequently used film can be quickly taken out when the frequency of the used film is different.
