Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a reversal mount storage mechanism for storing a reversal mount in a storage means such as a magazine for storing a large number of reversal mounts.

[Background Art] A reversal film that can be projected by a projector or the like is attached to a frame-shaped reversal mount. When printing images on this reversal film on a printer such as photographic paper, a worker manually feeds the reversal mount one sheet at a time to the printer. Therefore, quick and automatic printing of reversal films is not possible. Additionally, reversal mounts are thin, and each type has a different thickness, shape, and weight, making them difficult to handle and hindering automation.

[Purpose of the invention] Taking the above facts into consideration, the present invention provides a method for quickly and efficiently attaching a reversal mount to a storage means such as a magazine when storing a large number of reversal mounts in a storage means such as a magazine to improve the efficiency of printing operations. The object is to obtain a reversal mount storage mechanism that can be automatically stored.

[Summary of the invention] In this invention, the reversal mount is fed while sliding on a conveyance path with a groove-shaped cross section in the width direction.
A reversal mount storage mechanism for inserting the reversal mount into an open pocket of a storage means disposed on the downstream extension of the conveyance path, the reversal mount storage mechanism being configured to press an end of the reversal mount opposite to the pocket. An ejector rod that sends this reversal mount to the downstream side of the conveyance path, and this ejector rod is moved on an arc touching the conveyance path to enter from outside the conveyance path into the conveyance path and correspond to the end of the reversal mount. The first guide means and the ejector rod that has reached the conveyance path are connected to the first guide means.
The reversal mount storage mechanism is characterized by having a second guide means that moves linearly toward the downstream side of the conveyance path together with the guide means to store the reversal mount in the pocket.

For this reason, in the present invention, when the reversal mount is fed along the groove-like conveyance path, the first guide means causes the ejector rod to correspond to the end of the reversal mount. This first guide means moves the ejector rod on a circular arc touching the conveyance path so that the ejector rod corresponds to the end of the reversal mount, so that the ejector rod moves to the end of the reversal mount after the wobbling at the beginning of the movement of the ejector rod has stabilized. do. In particular, since it moves on a circular arc in contact with the conveyance path, even if the reversal mount is thin, it can accurately reach the end of the reversal mount without coming off the reversal mount.

The ejector rod corresponding to the end of the reversal mount is linearly moved by the second guide means and accommodated in the open pocket, so that the ejector rod does not come off the reversal mount and can accurately apply the moving force. It is then inserted into the pocket.

In this way, in the present invention, the guide means for making the ejector correspond to the end of the reversal mount and the means for moving the reversal mount linearly to the pocket are separated, so the mount moving mechanism can be moved to the side of the magazine that has the pocket. Even without the provision, reversal mounts that are thin and different in thickness, shape, and weight can be reliably matched to the end of the reversal mount with an ejector rod, and can be reliably accommodated in a pocket.

[Embodiment of the invention] FIG. 1 shows an input device 12 to which a reversal mount storage mechanism 10 according to the invention is applied.

In this input device 12, the mount board 14
A print correction information input section 16 is provided adjacent to. The reversal mount 18 placed on the mount board 14 is formed into a frame shape of synthetic resin, cardboard, etc., and the reversal film 20 is held therein.

The print correction information input section 16 allows an operator to visually check the reversal film 20 on the mount board 14 and input print conditions such as color correction. The information is recorded in an IC memory of a storage device 24 of a magazine 22 as a storage means arranged adjacent to the input reversal mount storage mechanism 10.

A reversal mount transport device 25 is provided on the side of the input device 12, and in this reversal mount transport device 25, a frame 26 is supported to the input device 12 via a vibration isolating rubber 28.

In the reversal mount transfer device 25, the insertion port 3
0 is the mount board 14 and turntable 3
2 are connected. The turntable 32 has a disk shape with a vertical axis, and a conveyance path 34 is formed from one end to the other end.

This turntable 32 has a shaft 40 protruding from the bottom surface, and this shaft 40 is connected to a rotary solenoid 42.
2, in which the conveyance path 34 is connected to the insertion port 30, and can be rotated 90 degrees counterclockwise to connect the conveyance path 34 with the conveyance path 44. There is. Therefore, the turntable 32 receives the reversal mount 18 sent into the insertion port 30 and delivers it to the conveyance path 44.

Correspondingly, drive rollers 64 and press rollers 48 are arranged at appropriate intervals on both sides of the insertion port 30, the conveyance path 34, and the conveyance path 44, respectively.
The reversal mount 18 being sent in is conveyed while being held therebetween.

A front/back determining means 50 is provided in the intermediate portion of the conveyance path 44 . This front/back determining means 50 temporarily heats the reversal film 20 of the reversal mount 18, and utilizes the property of the reversal film 20 to bend toward the emulsion side due to an increase in temperature to ensure that the reversal mount 18 is inserted in the normal state. If it is inserted upside down, it is sent to the discharge port 52 via the conveyance paths 44, 34, and the worker turns it over and sends it out to the conveyance path 44 again. It is becoming possible to do this. In addition, this front/back determining means 50 uses autofocus to determine the focus position during printing by automatically determining the height of the reversal film 20 from the back surface of the reversal mount 18 at the same time as determining the front/back of the reversal mount 18. It's starting to work.

In place of this front/back determining means, or a separate means for detecting the vertical and horizontal insertion state of the reversal mount may be provided.

A reversal mount storage mechanism 10 is attached to the other end of the conveyance path 44. In this reversal mount storage mechanism 10, as shown in FIGS. 3 and 4, an ejector rod 54 comes into contact with the rear end of the reversal mount 18 being conveyed on the conveyance path 44, and feeds it into the pocket 56 of the magazine 22. ing.

The ejector rod 54 has a bent portion 54A whose central portion is bent at right angles in the direction approaching the conveyance path 44, and the tip of this bent portion 54A forms a protruding portion 54B bent toward the magazine 22. ing. The tip of this protruding portion 54B is adapted to abut against the rear end of the reversal mount 18.

Parallel links 58, 5 are provided at the base of the ejector rod 54.
The tips of 9 are pivotally supported by pins 60 and 61, respectively. The bases of these pins 60 and 61 are pin 6
2 and 63 are pivotally supported on a sliding shaft 64. Therefore, between the pins 62 and 63 of the sliding shaft 64, the parallel link 5
8, 59 and the pins 60, 61 of the ejector rod 54 constitute a parallel link mechanism which is a first guide means, and when the parallel links 58, 59 rotate around the pins 62, 63, the ejector rod 54 becomes horizontal. The projecting portion 54B moves up and down while maintaining the state, thereby causing the protruding portion 54B to move up and down while maintaining the reversal mount 18 on the conveyance path 44.
It is designed to descend from outside the movement trajectory into the movement trajectory.

A tension coil spring 65 is interposed between the parallel link 59 and the sliding shaft 64, and urges the ejector rod 54 to move out of the movement locus of the reversal mount 18.

The sliding shaft 64 constitutes a second guide means, and is guided by a guide pin 66 that is attached to the frame 26 and has a horizontal axis, so that it can slide in the direction toward and away from the magazine 22. A tension coil spring 68 is interposed between the sliding shaft 64 and the frame 26, and is biased in a direction away from the magazine 22 by this. Further, a guide roller 70 whose axis is vertical is supported on the top surface of the sliding shaft 64, and this guide roller 70 comes into contact with a long hole 73 of a guide plate 72 fixed to the frame 26. This prevents the sliding shaft 64 from rotating around the guide pin 66.

A rotary solenoid 74 whose axis is horizontal is fixed above the sliding shaft 64, and a swing arm 76 is fixed to the output shaft 74A of the rotary solenoid 74. The tip of this swing arm 76 is pivotally supported by a pin 61, and when a rotary solenoid 74 is excited by this, the swing arm 76 swings, lowering the ejector rod 54 and moving within the movement trajectory of the reversal mount 18. It is now being moved to After this swing arm 76 has turned by a predetermined angle, that is, after the protruding portion 54B of the protruding rod 54 enters the movement locus of the reversal mount 18, it comes into contact with an abutting plate 78 fixed to the sliding shaft 64. There is. As a result, after the swing arm 76 comes into contact with the contact plate 78, the sliding shaft 64 is moved in a direction toward the magazine 22 against the urging force of the tension coil spring 68.

Note that the rotary solenoid 74 is connected to the conveyance path 44.
A sensor 79 provided at the end of the reversal mount 18 is activated when it detects passage of the reversal mount 18.

As shown in FIGS. 2 and 5, a pair of arms 80 and 82 protrude from the frame 26 between the transport path 44 and the magazine 22 so as to sandwich the transport path 44 therebetween. Shafts 84 and 86 coaxially protrude from these arms 80 and 82, respectively, in a direction perpendicular to the conveyance path 44 and in a direction away from the conveyance path 44.

Intermediate portions of links 88 and 90 are supported by these shafts 84 and 86, and these links intersect with each other. Pins 92 and 94 pivotally supported at the tips of links 88 and 90 are connected to pinching rollers 96A and 96B.
are fixed to the pins 98, 100 which are pivotally supported at the intermediate portions of the links 88, 90, and the pinching rollers 102A,
102B is fixed. The distances between the pins 92, 94 and the shaft 84 or 86 are equal to each other and the distance between the pins 98, 100 and the shaft 84 or 86. Further, the pins 94 and 100 are connected to the conveyance path 44.
A pair of pinching rollers 96B on opposite sides of the
and a pair of nipping rollers 102B are arranged coaxially.

Furthermore, the other ends of the links 88 and 90 are connected to the links 106 and 10 by pins 104 as shown in FIG.
8 and these links 106, 10
The other ends of 8 are connected to each other by a pin 110. A tension coil spring 11 is connected between this pin 110 and a spring receiving pin 112 protruding from the frame 26.
4 is interposed.

Therefore, the links 88 and 90 constitute a pantograph mechanism, and the pinching rollers 96A, 96B and 1
02A, 102B are the shafts 84 of the links 88, 90,
When rotating about 86, they move toward and away from each other by an equal distance, and are biased toward each other by a tension coil spring 114. Also axis 8
4, 86, that is, the pinching rollers 96A,
The center of the thickness of the reversal mount 18 held between 96B, 102A, and 102B is aligned with the center of the vertical interval of the magazine pocket 56. As a result, the holding roller 96A, which is sent through the conveyance path 44,
The reversal mount 18 held between 96B, 102A, and 102B is inserted with the center of its thickness aligned with the center of the pocket 56, allowing accurate storage without insertion errors.

Pinion 116, which is secured to shaft 84 as shown in FIG. 5, meshes with pinions 118, 120 which are secured to pins 94,100. Also, the shaft 84
A belt 124, which is wound around a pulley 122 fixed to the belt 122, is rotated by the driving force of a motor (not shown). Therefore, the pinching roller 96
B, 102B is designed to rotate clockwise in FIG. 6 to apply force in the direction of sending the clamped reversal mount 18 into the magazine 22. For this purpose, it is preferable that the nipping rollers 96B and 102B are made of a material with a large frictional force, such as a rubber roller.

Note that these nipping rollers 96B and 102B are driven when the reversal mount 18 passes the front/back determining means 50.

Next, the operation of this embodiment will be explained.

The reversal mount 18 on the mount placement board 14 is sent to the conveyance path 34 through the insertion port 30 after the print condition correction signal is determined. The turntable 32 rotates 90 degrees and sends the reversal mount 18 into the conveyance path 44.

The reversal mount 18 sent into the conveyance path 44 is subjected to front/back determination and autofocus work by the front/back determining means 50, and then is moved to the reversal mount storage mechanism 10.

The nipping rollers 96B and 102B, which are driven by the passage of the front/back determining means 50, send the reversal mount 18 sent by the drive roller 46 of the conveyance path 44 and the press roller 48 into the pocket 56 of the magazine 22. In this case, the pinching roller 96
A, 96B, 102A, and 102B always align the center of the thickness of the reversal mount 18 with the center of the pocket 56 regardless of the thickness of the reversal mount 18, so there is no insertion error.

When the end of the reversal mount 18 comes off the clamping rollers 96A and 96B, the clamping roller 96
Although no driving force is received from A or 96B, the sensor 79 that detects the passage of the reversal mount 18 excites the rotary solenoid 74.

As a result, the pivot arm 76 pivots, and the protruding portion 54B of the ejector rod 54 is lowered from outside the movement trajectory of the reversal mount 18 into the movement trajectory due to the rotation of the parallel links 58 and 59. When the swing arm 76 further rotates, it comes into contact with the contact plate 78, and the sliding shaft 64 is moved along the guide pin 66 toward the magazine 22. The protrusion 54B thus presses against the tail of the reversal mount 18 and forces it into the pocket 56. The locus of movement of the tip of the protrusion 54B is indicated by an arrow P in FIG.

In this way, the ejector rod 54 can reliably store the reversal mount 18 in the pocket 56 even if the magazine 22 has no storage mechanism for the reversal mount 18.

In this way, there is a mechanism (parallel links 58, 59) that moves the ejector bar 54 from outside the movement axis trace of the reversal mount 18 into the movement trace, and a mechanism (sliding shaft 64, pin 66) that pushes it toward the pocket.
Since these are separated, the ejector rod 54 can accurately correspond to the end of the thin reversal mount 18, and can be accurately driven linearly.

After the pushing operation is completed, the excitation of the rotary solenoid 74 is released, and the tension coil spring 65,
Due to the biasing force 68, the guide pin 66 and the parallel links 58, 59 return to the solid line state shown in FIG.

Thereafter, the above operations are repeated in the same manner, and the reversal mounts 18 are sequentially stored in the magazine 22.

Note that in the above embodiment, the structure in which the reversal mount 18 is stored in the magazine 22 has been described.
The present invention is not limited to this, but the reversal mount 18
The present invention is applicable to all cases where the reversal mount 18 is stored in a storage means having a pocket for storing the reversal mount 18.

Furthermore, the present invention is not limited to the storage mechanism using the parallel link mechanism and the guide pin 66, but also includes the ejecting rod 54.
Other guide means, such as a cam, can also be applied to move the reversal mount 18 from outside the movement path into the movement path and push it into the pocket. In this case, the first guide means and the second guide means may be operated by the same mechanism. In addition, the pinching roller 96
Instead of the pantograph mechanism for guiding the holding rollers 96A, 96B, 102A, 102B, other mechanisms can be applied.
Any equidistant movement means that can move 2B toward and away from each other by an equal distance may be used.

[Effects of the invention] As explained above, in the reversal mount storage mechanism according to the present invention, the first guide means moves the ejector rod from outside the movement trajectory of the reversal mount to within the movement path, and the second guide means moves the ejection rod in a straight line. Since the reversal mount is automatically driven to be stored in the storage means, it has an excellent effect of enabling automatic processing of the reversal mount.
