CONSTITUTION:The takeout means 26 is arranged nearby the film entrance and exit of a loaded cassette 18 and a sucker 28 takes an exposed sheet film F out of the cassette main body 18A by receiving the driving force from a driving source and passes it to conveyor rollers 32. Those conveyor rollers 32 receive the driving force from the driving source and send out the exposed sheet film F to a developing device 34 (as shown by an arrow B). Consequently, the film is not flawed while conveying it from the magazine to the cassette and even when many magazines are arranged vertically, the overall height of the device need not be increased.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sheet film loading device for taking out sheet film from a magazine and loading it into a cassette.

[Conventional technology]

As a device for loading X-ray film into an imaging cassette, a device has been proposed in which a suction means takes out a sheet film from a magazine and loads it into the cassette (Japanese Patent Laid-Open No. 249833/1983). This device is
The line sheet film is sorted by type and stored in a plurality of magazines, and the suction means suctions the edge of the film in the selected magazine and takes it out, and transfers it to the feed roller disposed in the cassette loading section. It is designed to be held inside. For this reason, the suction means doubles as a means for taking out the film from the magazine and a means for transporting the film, but by the time the suction means takes out the film from the magazine and brings it into the cassette, the end of the film may come into contact with other parts nearby. Easy to damage the film.

There is also a device that takes out a sheet film from a magazine using a suction means, stores the sheet film in an arc shape in a holding frame, transports this holding frame to a position corresponding to a cassette, and loads the sheet film into the cassette. has been proposed (International Publication WO88106749).

In this device, the sheet film taken out from the magazine is transferred from the magazine to the cassette while being housed in the holding frame, so the film does not come into contact with other parts and be damaged during transfer. However, in this device, the driving force for storing the sheet film into the holding frame and the driving force for feeding the sheet film from the holding frame into the cassette are provided by the suction means, so that the suction means suctions the edges of the sheet film, and It is necessary to insert the sheet film from one end of the holding frame and take it out from one end of the holding frame even when feeding it into a cassette. Therefore, when a plurality of magazines are arranged vertically, one end of this holding frame must be able to move up and down to accommodate all the magazines, which increases the installation height of the entire apparatus.

[Problem to be solved by the invention]

In consideration of the above facts, the present invention has developed a sheet that does not damage the film during film transfer from the magazine to the cassette, and eliminates the need to increase the overall height of the device even when a large number of magazines are arranged vertically. The objective is to obtain a film loading device.

[Means and effects for solving the problem 3 The invention of claim (1) of the present application is a sheet film loading device that selects and takes out sheet films from a plurality of magazines and loads the sheet films into a cassette. a take-out means for taking out a sheet film from the magazine; and a take-out means that is movable separately from the take-out means and receives the sheet film from the take-out means from one end of the holding part so that the sheet film is at least partially curved. a holding means for holding the holding part and feeding it into the cassette from the other end of the holding part; and a driving means for making the ejecting means and the holding means correspond to one of the magazines and separating the holding means from the ejecting means to correspond to the cassette. It is characterized by having the following.

The invention of claim (2) of the present invention is a sheet film loading device that selects and takes out a sheet film from a plurality of magazines and loads the sheet film into a cassette, the device taking out the sheet film from the magazine. a take-out means, connected to the take-out means, receives the sheet film from the take-out means from one end of the holding part, holds the sheet film in at least a partially curved state, and feeds the sheet film into the cassette from the other end of the holding part; It is characterized by having a holding means, and a driving means for integrally driving the ejecting means and the holding means from a state in which the ejecting means and the holding means correspond to any magazine to a state in which the holding means corresponds to the cassette. It is said that

Therefore, in the present invention, one end of the holding means corresponds to one of a plurality of magazines, and a sheet film taken out from the magazine by the taking out means is inserted into this one end. The sheet film is bent at least partially into a curved state within the holding means, and the insertion tip corresponds to the other end. Therefore, when the held sheet film is loaded into the cassette, the other end of the holding means corresponds to the cassette entrance. Therefore, when a large number of magazines are arranged one above the other, the holding means can be arranged so that one end of the sheet film, which is the inlet part, is placed downward and the other end, which is the exit part, is placed upwardly. Make it possible to respond,
Since the other end disposed at the top only needs to correspond to the cassette, even when the holding means corresponds to the magazine at the lowest stage, it does not protrude significantly downward from the apparatus or increase the overall height of the apparatus.

In addition, if the ejecting means and the holding means are movable separately and each corresponds to a magazine, and when successive sheet films are to be taken out from within the same magazine, only the holding means need be moved between the cassette and the magazine. The means can be kept in a stopped state corresponding to the magazine, allowing for rapid loading and unloading of sheet films.

[Embodiments of the invention]

FIG. 1 shows a sheet film loading device 10 to which the present invention is applied.

In this sheet film loading device 10, a frame is formed by a frame 11, and an outer plate 11A fixed to the frame 11 has a light-shielding structure inside. A plurality of magazines 12 are installed at the lower part of the frame 11, and sheet films F are stored in each of these magazines 12. These sheet films F are of different types (sizes,
film type), and the desired sheet film F
is removed from the cassette 18 by the ejecting means 14 and the holding means 16.
It is designed to be loaded inside.

However, it is not limited to the case where different types of films are housed in each magazine 12, and when there is a frequently used film, the same type of film may be housed together in a plurality of magazines.

When this cassette 18 is manually loaded into the interior through the loading port 10A (usually shielded) provided at the top of the sheet film loading device 10 (in the six directions of arrows), it is pulled in by the driving force of the cassette drive mechanism 20. 1 and placed in the position shown in FIG.

As shown in FIG. 3, this cassette 18 has a dish-shaped cassette main body 18A whose interior is used as a housing portion for the sheet film F, and a lid plate 18B is pivotally supported by one end of this cassette main body 18A. The inside can be opened and closed. A claw 22 protruding from the tip of the cover plate 18B engages with a window 18c formed in a part of the cassette body 18A to maintain the closed state of the cassette body 18A, but the cassette drive mechanism 20 does not open the cassette 18. By pressing the lid bin 24, the lid opening bin 24 pushes the claw 22 into the cassette main body 18A, and the lid plate 18B is opened as shown in FIG. 3 by the biasing force of an elastic body (not shown). has been done.

Further, as shown in FIG. 1, a take-out means 26 is arranged near the film entrance/exit of the loaded cassette 18.
The suction cup 28 receives a driving force from a driving source (not shown) to take out the photographed sheet film F from the cassette main body 18A and transfer it to the conveyance roller 32. These conveyance rollers 32 receive driving force from a drive source (not shown) and send out the photographed sheet film F to the developing device 34 (in the direction of arrow B).

Note that when the cassette 18 is loaded into the sheet film loading device IO and the lid plate 18B is opened by the lid opening bin 24, a lid opening/closing mechanism (not shown) (for example, Utility Model No. 63-1
41950 and Utility Model Application Publication No. 63-141951), the cover plate 18B is opened further,
When a new sheet film F is loaded after taking out the photographed sheet film F, the lid plate 18B may be closed and the sheet film F may be pushed out from the loading opening 108.

As shown in FIG. 2, the magazine 12 is formed in the shape of a deep dish, and a large number of unexposed sheet films F are stored therein in a stacked state. The upper end surface of this magazine 12 has a fixed cover plate 12A that closes the half opposite to the ejecting means 14, and the other half serves as an ejecting opening 12B. A slide lid 12C corresponds to the extraction opening 12B, and this slide lid 12C is connected to the extraction opening 12B as shown in FIG.
It is possible to slide the cover plate 12A under the cover plate 12A from a state in which the cover B is securely closed, and move to a state in which the take-out opening 12B is opened.

These magazines 12 are each housed in a movable table 36 installed in multiple stages on the frame 11 of the sheet film loading device 100. These moving platforms 36 are formed into a frame shape that supports the peripheral bottom of the magazine 12, and are formed with bent portions 36A that project horizontally from the upper ends of both sides. The core rests on horizontally pivoted rollers 38. Each movable table 36 is in a standby position when the magazine 12 is loaded in the state shown by the solid line in FIG. C direction) The pulled out state is the replenishment position for the sheet film F. Further, the magazine 12 is moved from the standby state to the right in FIG. 1 (in the direction of the arrow), and the film ejection position is reached when the ejection opening 12B reaches below the ejection means 4. In order to stop the magazine 12 at a predetermined position while the sheet film F is on standby, a notch 36B is formed in the bending part 36A, and when this 1 m 36B corresponds to the roller 38, the movement of the moving table 36 is stopped. It looks like this.

As shown in FIG. 2, the take-out means 14 is provided with a pair of lifting frames 122 parallel to each other.

These elevating frames 122 are connected to a plurality of connecting rods 12.
4 and are fixed in parallel to each other, and a guide shaft 128 passes through a guide block 126 fixed to the outside. Further, a similar guide block 127 is fixed to one side of the elevating frame 122, and a screw shaft 132 is screwed into the guide block 127.

The guide shaft 128 and the screw shaft 132 have vertical axes, and both upper and lower ends of the guide shaft 128 are fixed to the frame 11, and the screw shaft 132 is supported by the frame 11 and is driven by a motor (not shown). It rotates when it receives force. Therefore, when the screw shaft 132 rotates under the influence of the motor driving force, the take-out means 14 is raised or lowered so that it can correspond to each.

A suction cup 136 is disposed between these elevating frames 122 at the tip of an arm 134, and this arm 134 is pivotally supported by a shaft 138 to the tip of an arm 142. The arm 142 is supported by a shaft 144 on the lifting frame 122 . Further, motors 146 and 148 for controlling the rotation angles of these arms 134 and i4.2 are connected to arm 1, respectively.
42, attached to the lifting frame 122, endless belt 1
52.154 to transmit the rotational force to the arms 134.142.

As a result, the suction cup 136 moves approximately vertically downward from the state shown in FIG. The leading end of the sheet film F thus attracted is sent out to the holding means 16.

A pulley 62.64 is pivotally supported at the lower part of the lifting frame 122 by a support shaft 56.58.

An endless timing belt 6 is attached to these pulleys 62 and 64.
6 is wrapped around it. The support shaft 58 is the elevating frame 122
It is rotated by receiving the driving force of a motor 68 fixed to. Further, a pull-out pin 72 is fixed to a part of the endless timing belt 66, and its axis is connected to the pulley 62.
64, and corresponds to the engagement arm 74 fixed to the front end of the moving table 36. This engagement arm 74 is a drawer bin receiving portion 7 that opens downward in a U-shape.
4A, and when the endless timing belt 66 is rotated clockwise in FIG.
74A, so that the movable table 36 is pulled out together with the magazine 12 in the direction of the arrow below the take-out means 14 to reach the film take-out position. Note that a notch 74B is formed in the engagement arm 74 to avoid interference with the pulley 62 and the endless timing belt 66.

When the movable table 36 is pulled out to the film ejection position by the rotation of the pulleys 62 and 64, the arm 12 protruding upward from the slide lid 12C of the magazine 12 midway
D comes into contact with the magnetic adsorption piece 76 installed on the connecting rod 124 of the elevating frame 122 and is prevented from moving, so the magazine 12 moving together with the moving table 36 and the slide lid 12C move relative to each other, and the ejection opening 12B opens. It is now open. Furthermore, when the movable table 36 and the magazine 12 are returned to the standby position by reverse rotation of the pulleys 62 and 64, the adsorption piece 76 prevents the slide lid 12C from moving with magnetic force, so the slide lid 12C moves relative to the magazine 12. Then, the extraction opening 12B is closed.

As shown in FIG. 2, the holding means 1G includes a pair of elevating frames 42 fixed in parallel to each other by a plurality of connecting rods 44, and the sheet film F is held between these elevating frames 420. .

Guide block 4 fixed to the outside of the lifting frame 42
A guide #148 whose axis is perpendicular and whose upper and lower ends are fixed to the frame 11 passes through the guide #6. A screw shaft 52 is screwed into a similar guide block 47 on one of the lifting frames 42, and this screw shaft 52 is arranged parallel to the guide shaft 48. Therefore, when the screw shaft 52 rotates under the driving force of a motor (not shown), the elevating frame 42 moves up and down to a predetermined position so that it can accommodate each magazine 12 and cassette 18.

A pair of upper and lower entrance clamping rollers 82 are pivotally supported in parallel to each other between the elevating frames 42 near their lower ends. These entrance holding rollers 82 are for receiving the sheet film F taken out from the magazine 12 by the suction cup 136, feeding it in the direction of arrow E, and holding the sheet film F curved in an approximately semicircular shape. In addition, a pair of intermediate portion nipping rollers 84 and a pair of intermediate portion nipping rollers 86 are pivotally supported in correspondence with the intermediate portion of the sheet film F held in a semicircular shape, in the same manner as the entrance nipping roller 82 . Furthermore, a pair of outlet clamping rollers 88 are provided for clamping the leading end of the sheet film F held in a semicircular shape. Therefore, when a long sheet film F is held, the rear end of the sheet film F is held by the inlet holding roller 82, the middle part is held by the intermediate holding rollers 84 and 86, and the leading end is held by the exit holding roller 88. That will happen. Further, even when the sheet film F is short in size, the leading end portion is always held by the exit nipping roller 88.

The outlet clamping roller 88 is supported near the tip of a tilting frame 94 which is supported by a shaft 92 on the lifting frame 42 . A first swing link 97 is pivotally supported at the tip of the tilting frame 94 by a pin 96, and the other end of the first swing link 97 is pivotally supported by a pin 98 to a second swing link 99. This second swing link 99 is pivotally supported by a rotating shaft 100 that is connected to the lifting frame 42, and a pulley 102 fixed to this rotating shaft 100
A part of the endless bell [04 is wrapped around it. The other part of the endless belt 104 is wound around a pulley 108 that is fixed to the output shaft of a motor 106 that is fixed to the lifting frame 42.

Therefore, when the motor 106 rotates, the second swing link 99 rotates together with the rotating shaft 100, and the second swing link 97 receives this rotational force and moves the tilting frame 94 counterclockwise (in the direction of arrow G) as shown in FIG. It is designed to tilt towards. As a result, the sheet film F is loaded into the cassette 1 with its leading end being clamped by the outlet clamping rollers 88.
The sheet film F is moved above the entrance of the cassette 8 to facilitate insertion of the sheet film F into the cassette 18.

On the outside of the pull lifting frame 42 shown in FIG. Multiple pieces are used.

Next, the operation of this embodiment will be explained.

When the cassette 18 containing the photographed sheet film F is loaded from the loading opening 10A into the sheet film loading device 10 in the direction of the arrow, the cassette drive mechanism 20 pushes the cassette 18 toward the open-lid bin 24. The cover plate 18B is opened as shown in FIG. 1.3.

Next, the suction cup 28 of the ejecting means 26
Since the sheet film F inside is sucked and taken out and delivered to the conveyance roller 32, this photographed sheet film F
is sent to the developing device 34 and developed.

Next, a film type identification signal (not shown) attached to the cassette 18 is detected by a detection means (not shown), and the sheet film F to be loaded into the cassette is selected. The take-out means 14 and the holding means 16 are moved to the magazine 12 in which the selected sheet film is stored in response to a signal from the detection means. This movement is caused by the screw shaft 52 guiding the lifting frame 42 and the lifting frame 12.
When the screw shaft 132 guiding the lift frame 2 rotates under the driving force of a motor (not shown), the lifting frame 42 and the lifting frame 122 move up and down.

The ejecting means 14 and the holding means 16 are connected to this particular magazine 12.
1, the motor 68 rotates and the endless timing belt 66 is rotated clockwise in FIG. As a result, the pull-out bin 72 engages with the engagement arm 74 to move the movable table 36 from the standby position of the magazine 12 to the film take-out position. As the magazine 12 moves, the arm 12D of the slide lid 12G comes into contact with the suction piece 76, so the slide lid 12C moves under the lid plate 12A and the take-out opening 12B is opened.

Here, the motors 146 and 148 of the take-out means 14 are rotated, and the suction cup 136 is pressed against the uppermost sheet film F in the magazine 12. At the same time, negative pressure from a negative pressure source (not shown) is transmitted to the suction cup 136, whereby the vicinity of the leading end of the sheet film F is attracted. Then sucker 136
is raised by the rotation of the motors 146 and 148 and lifted from the take-out opening 12B, and the sheet film F
is inserted between the entrance holding rollers 82. Here motor 1
12 rotates to send out 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. For this reason, the sheet film F passes from the inlet clamping roller 82 to the intermediate clamping rollers 84 and 86, the leading end reaches the intermediate clamping roller 86, and is curved into an arc with the leading end being clamped by the exit clamping roller 88. is retained. In order to smoothly move the sheet film F between these rollers, it is preferable to provide a guide plate 89 (shown in phantom lines in FIG. 1) inside the elevating frame 42.

When the sheet film F is stored in the holding means 16, the suction cup 136 of the ejecting means 14 returns to the standard position, the motor 68 reverses, and the movable table 36 returns the magazine 12 to the standby position.

At this point, the holding means 16 is raised by the rotation of the screw shaft 520, and the exit clamping roller 88 corresponds to the entrance/exit of the cassette 18, and the lifting of the holding means 16 is stopped.

The rotation of the motor 106 causes the tilting frame 94 to rotate counterclockwise (in the direction of arrow G) as shown in FIG. 1, so that the outlet clamping roller 88 passes over the open-lid bin 24 and approaches the vicinity of the entrance of the cassette 18. This allows the sheet film F
The leading end of the cartridge is securely accommodated in the cassette 18 by the rotation of the outlet nipping roller 88. In this way, the tilting frame 94 brings the outlet holding roller 88 close to the entrance of the cassette 18, so that the opening bin 24 for opening the lid plate 18B of the cassette 18 is placed in front of the cassette 18. Even if the sheet is filled from the holding means 16! ,, l
;' can be reliably loaded into the cassette 18.

When the sheet film F loaded in the cassette 18 passes through the holding means 16, its front and back sides are reversed, so that the sheet film F loaded in the cassette 18 is reversed from the state stored in the magazine 12. That is, since it is necessary to load the sheet film F into the cassette 18 with the emulsion side facing the lid plate 18B, if the film has an emulsion side on only one side, it is necessary to load the sheet film F into the cassette 18 with the emulsion side facing downward in the magazine 12. It will be accommodated. Therefore, since the suction cup 136 of the take-out means 14 adsorbs the opposite side of the emulsion, even if the film is sensitive, the suction force will not affect the photographic performance.

Note that even when the tilting frame 94 rotates counterclockwise in FIG. In order to prevent unnecessary tension from being applied to the sheet film F due to being pinched by the middle part holding rollers 84 and 86, the inlet holding roller 82 and the middle part holding rollers 84 and 86 are used.
It is preferable that a one-way clutch 156 be interposed between the belt and the winding boot of the timing belt 116 to allow free rotation when high-speed rotation is transmitted in the sheet film transport direction.

When the loading of the sheet film F into the cassette 18 is completed, the tilting frame 94 returns to the vertical position again, and the holding means 16 is ready for the next film removal, but in this embodiment, the removal means 14 is separated from the holding means 16. Since the sheet film F is moved up and down, if the sheet film F is to be taken out successively from the same magazine 12, the take-out means 14 must be stopped in correspondence with this magazine 12.
The extraction operation can be performed quickly. In this case, the magazine 12 may also be stopped while being placed at the film removal position.

Since the holding means 16 receives the sheet film F from the artificial clamp roller 82 arranged near the lower end, even if the holding means 16 moves to the lowest position when taking out the sheet film F from the lowest magazine 12, it will not be held. The means 16 does not protrude significantly below the lowest magazine 12, so there is no need to increase the overall height of the sheet film loading device 10.

Next, FIG. 4 shows a second embodiment of the present invention. In this embodiment, the tilting frame 94 of the first embodiment is omitted, and the exit conveyance roller 88 is directly supported by the lift frame 42. Therefore, the motor 106 and the like for driving the tilting frame 94 in the embodiment described above are not provided. In addition, the holding means 16 has the lifting frame 42 connected to the shaft 162.
The guide block 46 and the guide block 4 are pivotally supported on the outer bracket 164 at the outer bracket 164.
7 is fixed, and is guided by a guide shaft 48 and a screw shaft 52 to move up and down.

The shaft 162 also has a pin 96 between it and the outer bracket 164.
, a first swing link 97, a bin 98, a second swing link 99, and a motor 106 are interposed, and the motor 10
The holding means 16 is rotated around the shaft 162 by the driving force of 6, and the leading end of the sheet film F held between the exit conveying rollers 88 is brought closer to the cassette 18 as in the previous embodiment. Note that in this embodiment, the exit conveyance roller 88
At the same time, since the intermediate portion nipping rollers 84, 86 and the inlet nipping roller 82 are both rotated around the shaft 92, there is no need to use the one-way clutch I56 as in the previous embodiment.

Note that the other configurations are the same as those of the first embodiment.

Further, in the above embodiment, the sheet film F is inserted into the holding means 16.
Although the configuration in which the sheet film F is held in a semicircularly curved manner is shown, it is not necessarily necessary that the entire area of the sheet film F be curved, and a portion thereof may have a straight portion.

Further, in the above embodiment, a configuration is shown in which the take-out means 14 and the holding means 16 are moved up and down separately, but they may be connected together and moved up and down.

In the above embodiment, the sheet film loading device 10 is provided with both a means for taking out the sheet film F from the cassette 18 and a loading means. A configuration may be adopted in which only a means for loading the sheet film onto the sheet film 18 is provided.

〔Effect of the invention〕

Since the present invention has the above-mentioned configuration, it has excellent effects in that the sheet film is not damaged during transportation and there is no need to increase the size of the entire sheet film loading device.
