Abstract

PURPOSE:To feed an automatic developing machine with a photosensitive plate so quickly in a small floor space, by installing a lifting device which is driven separately from a separation device and which makes a supporting device go up. CONSTITUTION:When a motor is driven and an outer chain 76 is rotated, an intermediate part of a photosensitive plate 16, on a topmost layer, whose lower end is housed in a hook 64, is gradually separated from a mount 14 because each guide ring 84 goes up on the sensitized surface side, whereby it is transferred onto the upper part of a separation lifting part 18, and the reverse sensitized surface side hits on plural guide rings 46. When a detection switch detects an upper end of the photosensitive plate 16, the motor is driven, and an inner chain 60 and an outer chain 76 both are rotated at the same speed. With this rotation, the hook 64 goes up, lifting the photosensitive plate 16. Each ring 84 delivers the photosensitive plate 16 to space between pinch rollers 92 and 94 while holding it between these guide rings 46.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a photosensitive plate auto feeder for feeding exposed photosensitive plates to an automatic processor.

(Background technology) Using an automatic developing machine, photosensitive plates (the photosensitive layer whose solubility changes with light irradiation are aluminum plates, zinc plates, iron plates, paper, etc.)
When processing a large number of photosensitive plates (coated appropriately on both or one side of a support plate such as a plastic plate), a photosensitive plate auto feeder connected to an automatic processor is used. often. The automatic developing machine in this case has a structure in which the photosensitive plate is conveyed by rollers or the like, and is provided with a water washing zone, a gum coating zone, a drying zone, etc., as necessary, in addition to a developing zone.

Conventional photosensitive plate auto feeders, for example, stock multiple exposed photosensitive plates by stacking them horizontally on a mounting table installed in series on the photosensitive plate insertion slot side of an automatic processor, and feed them one by one. This photosensitive plate is sucked from above using a suction cup and sequentially fed into an automatic developing machine.

However, the photosensitive plate auto feeder described above has a width of, for example, 800 m11. When processing large photosensitive plates (e.g. psi) with a length of 1050 m+, these photosensitive plates need to be stored horizontally, which requires a fairly large area, and it is also difficult to capture the photosensitive plates. An extremely large installation space is required to create a structure equipped with means and a conveyance system.

In consideration of the above-mentioned facts, the present invention aims to provide a photosensitive plate auto feeder that requires less installation space and can efficiently feed photosensitive plates to an automatic processor.

[Summary and operation of the invention]

The present invention is a photosensitive plate feeding device for feeding an exposed photosensitive plate to an automatic developing machine, and includes a mounting table on which a plurality of photosensitive plates are vertically placed (131), and a mounting table (20) facing the mounting table. a supporting means for supporting the lower end of the photosensitive plate disposed as shown in FIG. a separating means that moves up between the supporting means and the mounting table to separate the top layer photosensitive plate from the mounting table; and a separating means that is driven separately from the separating means and lifts the supporting means to separate the uppermost layer photosensitive plate from the mounting table. The invention is characterized in that it has a lifting means for feeding the color plate from the upper end to the automatic developing machine.

Therefore, in the present invention, when a plurality of exposed photosensitive plates are placed on the mounting table, the lower end of the uppermost photosensitive plate among the plurality of photosensitive plates is moved onto the support means by the moving means. be dropped.

Here, the separating means moves up between the supporting means and the mounting table, so that the photosensitive plate whose lower end is moved to the supporting means and whose upper part is on the mounting table is gradually moved up from the lower part by the moving means [the mounting table]. be separated from

Here, the lifting means raises the support means and sends out the upper end thereof to the automatic developing machine, so that the plurality of photosensitive plates mounted on the i-mounting table are sent out to the automatic developing machine in sequence starting from the top layer. . In this way, the separating means and the lifting means are driven separately, so while the separating means is separating the uppermost photosensitive plate from the mounting table, the supporting means is moving the lower end of the photosensitive plate. can be supported reliably, and during this time there is no need for moving means such as G&D to continue holding the photosensitive plate.

Further, in the present invention, when the lifting means lifts the supporting means and the leading edge of the photosensitive plate is delivered to the automatic processor, the supporting means can be returned to the supporting position for the next layer of photosensitive plate, so that one sheet of The cycle for feeding the photosensitive plate to the automatic developing device can be made faster.

[Embodiments of the invention]

1.2 shows a photosensitive plate auto feeder according to the present invention connected to an automatic processor 12. As shown in FIG. In the photosensitive plate auto feeder in this embodiment, a large number of photosensitive plates 16 that have been exposed in a separate process are stacked and stacked in a vertical direction R on an inclined mounting table 14, and these plates are sequentially transferred to an automatic developing machine 1 by a separating section 18. It is designed to be sent to

There are protrusions 22 on both sides of the mounting table 14 and the frame 20 (however, the protrusions 22 on the near side are not shown in FIG. 2).
Support pieces 24 are respectively protruded from the lower ends, and the lower ends of the exposed photosensitive plates 16 are sequentially placed on the support pieces 24. The angle of inclination of the frame 20 from the vertical line is about 8 degrees. For this reason, the exposed photosensitive plate 16 is sequentially polymerized from the right side in FIG. 2, so that the uppermost layer faces the separation supporter 18.

In this case, it is preferable that the photosensitive plate 16 having a photosensitive surface on one side of each support face the photosensitive surface opposite to the separating member 18.

As shown in FIG. 3, a pair of side plates 28 and 30 are erected on both sides of the separation holding upper part, and these side plates 2B
, 30 are connected by a bottom plate 32. As shown in FIG. 2, these side plates 28 and 30 are connected at their upper ends by a support shaft 34 and at their lower ends by a support shaft 36.3, so that they are parallel to each other.

Posts 40 are respectively projected from the opposing surfaces of the side plates 28, 30, and inner guide plates 42 are fixed to the tips of these posts 40, respectively.

Therefore, these inner guide plates 42 are connected to the pair of side plates 28.3.
0 and are parallel to each other, and among these, guide temporary 4
The two are connected by a plurality of support shafts 44.

A plurality of guide rings 46 are supported on each of these support shafts 44 at regular intervals. These guide rings 46 are for supporting the photosensitive plate 16 separated from the mounting table 14, and as shown in FIG. The guide ring 46 that is pivotally supported on the support shaft 44 is gradually separated from the mounting table 14, and the photosensitive plate 16 separated from the mounting table 14 is supported at an opposite angle to the vertical axis from the supporting angle to the mounting table 14. It is supported at an angle.

Support plates 48 are attached to the plurality of support shafts 44 with screws 50, and these support plates 48 have a plurality of notches 52 for allowing a portion of the guide ring 46 to protrude toward the mounting table 14 side. It is formed. As a result, the photosensitive plate 16 supported on the guide ring 46 may be accidentally moved to the second position.
In the figure, care is taken to prevent the guide ring 46 from being pulled out to the left side.

A rotary shaft 54 is supported parallel to the side plates 28 and 30 between the second and third support shafts 44 from the top of the plurality of support shafts 44, and a sprocket wheel 56 is fixed. These sprocket wheels 56 are arranged above the inner guide plate 42, and an inner chino 60 is wound around each sprocket foil 56. This inner chino 60 is the support shaft 3
The other part is wrapped around a sprocket foil 62 fixed to the sprocket wheel 8, and is adapted to move along the surface of the inner guide plate 42 between these sprocket wheels 56 and 62.

This inner chino 60 has a hook 64, which is a mounting table, fixed at its longitudinal end. This hook 64 has a V-shaped side surface as shown in FIG. The lower end portion of the uppermost photosensitive plate 16 among the plurality of photosensitive plates 16 installed on the mounting table 14 is accommodated therein. Further, a motor 66 is attached to the rotating shaft 54, so that the rotating shaft 54 can be rotated clockwise and counterclockwise in FIG. Therefore, by rotating the sprocket wheel 62 in the counterclockwise direction as shown in FIG. It looks like this.

Movement of the hook 64 is restricted by a limit switch 58A1 mounted near the sprocket wheel 62 and an upper limit switch 58B mounted near the sprocket wheel 56.

As shown in FIG. 3, the supporting shaft 34 and the sprocket foil 70. are located between the side plates 28, 30 and the inner guide plate 42 when viewed from the front. A sprocket foil 72 is attached to the support shaft 38, a sprocket foil 74 is further attached to the support shaft 36, and an outer chino 76 is wound around each. These outer chinos 76 can be rotated clockwise and counterclockwise in FIG. 2 by receiving the driving force of a motor 78 connected to the support shaft 38.

These outer chinos 76 are guided by an outer guide plate 80 disposed between the support shaft 34 and the support shaft 38. These outer guide plates 80 extend above the support shaft 38 in parallel with the inner chino 60, and
At the upper part of the sprocket wheel 70, it is bent into an arc shape, and its extension line constitutes a tangent to the pitch circle of the sprocket wheel 70.

Further, a plurality of connecting shafts 82 are extended between the outer chains 776, and guide rings 84 similar to the guide ring 46 are supported at equal intervals in the intermediate portions of these connecting shafts 82.

Therefore, these guide rings 84 are attached to the photosensitive plate 1.
When the lower end of the photosensitive plate 16 is mounted on the hook 64 and rotated counterclockwise in FIG. It is supposed to be moved.

Note that, as shown in FIG. 7, a notch 85 is formed in a part of the hook 64 through which a guide ring 84 passes.

In order to control the stroke of these outer chinos 76, an upper limit switch 86 is disposed near the sprocket wheel 70 and a lower limit switch 88 is disposed near the sprocket wheel 72.

As shown in FIG. 6, a stay 67 is attached to the leading edge and the next connecting shaft 82 attached to the outer chino 76 that moves counterclockwise in FIG.
A photosensitive plate detection switch is installed on the 6th. This photosensitive plate detection switch 6 is a reflective optical sensor, and is capable of detecting the tip of the photosensitive plate 16 that has been transferred from the mounting table 14 to the separating support section 18.

A pair of clamping rollers 92 and 94 constituting a part of the automatic developing machine 12 are arranged adjacent to the sprocket wheel 70, and clamp the leading end of the photosensitive plate 16 that is raised along the separating support section 18. The film is then fed into the automatic developing machine 12.

For this reason, these clamping rollers 92 and 94 are used for automatic development! a
It has the same peripheral speed as the developing speed in 12.

A moving means 112 is provided at the bottom of the 2nd and 30th side plates. As shown in FIG. 4.5, this moving means 112 is provided with a pair of suction cups 114 and 116 for suctioning the photosensitive plate 16. These suction cups 11
4.116 is attached to the tip of the support shaft 118, so that negative pressure from a negative pressure source (not shown) is transmitted and the photosensitive plate 16 can be attracted by the negative pressure.

The support shaft 11B has an intermediate portion passing through the support plate 120, a tip portion thereof passing through the support plate 122, and these support plates 120.1
22 and can be slid.

An E-ring 124 is attached to the middle part of the support shaft 118,
A compression coil spring 126 is interposed between the E-ring 124 and the support plate 122. For this reason, these suction cups 114 and 116 are supported by the support plates 120 and 122, but the support plates 120 and 122 are pushed toward the mounting table 14, and the suction cups 114 and 116 are pressed against the photosensitive plate 16. When the support plate 120, 122 moves further,
The suction cups 114 and 116 are pressed against the photosensitive plate 16 by the elastic force of the compression coil spring 126 while compressing the compression coil spring 126.

The pressing rod 130, whose tip end and middle portion are fixed to the support plates 120 and 122, respectively, is slidable while being guided by a bearing 134 attached to the base plate 132.

A long link 138 is provided in the middle of the support plate 122 with a bin 136.
One end is pivoted. The other end of this long link 138 is pivotally supported by a pin 140 to one end of a short link 142.

Further, the other end of the short link 142 is fixed to the rotating shaft 144,
This rotating shaft 144 is connected to an output shaft 148 of a motor 146.

Therefore, the rotation of the motor 146 is transmitted as the rotational force of the short link 142, and the long link 138 receives this rotational force via the pin 140.
A reciprocating slider crank mechanism is configured to reciprocate the slider 22.

Here, the axial center of the rotating shaft 144 is arranged offset from the movement extension line of the reciprocating pin 136, thereby forming a rapid feed mechanism. In other words, the forward stroke and return stroke of the reciprocating movement of the pin 136 are performed by the short link 142.
This corresponds to the rotation angles θ1 and θ2. Therefore, the rotational speed of the rotating shaft 144, which rotates at a constant speed, is such that the rotation angle θ1 corresponds to the forward stroke of the suction cups 114 and 116, and the angle θ2, which is larger than this, corresponds to the return stroke, so the suction cup 114 and 116 quickly approach the wi mounting table 14, adsorb the photosensitive plate 16, and attach the adsorbed photosensitive plate 16 to the hook 6 at a slower speed.
It is designed to be pulled in four directions.

After suctioning the photosensitive plate 16, these suction cups 114 and 116 move the photosensitive plate 1 above the hook 64.
6 is moved, the negative pressure is released and the lower end of the photosensitive plate 16 is moved to the hook 64. In this case, only the uppermost photosensitive plate 16 of the photosensitive plates 16 mounted on the mounting table 14 is sucked by the suction cups 114 and 116, but the uppermost photosensitive plate 16 and the next layer If the plate 16 is in close contact with the top layer photosensitive plate 16, the next layer photosensitive plate 16 may be inadvertently pulled out while remaining in close contact with the top layer photosensitive plate 16. Therefore, after the suction cups 114 and 116 have suctioned the photosensitive plate 16, they are moved slightly to the left in FIG. 2 and then stopped temporarily.
It is preferable to allow time for outside air to enter between the top and bottom layers, so that the next layer of photosensitive plates can separate from the uppermost photosensitive plate 16 and slide down under its own weight, remaining on the support piece 24.

Furthermore, for this purpose it is necessary to place the photosensitive plate 1 onto the support piece 24.
It is preferable that a tape 154 provided with a plurality of small protrusions is pasted toward the end face of 6.

This tape 154 can be made of a material such as Velcro tape (trade name) having a plurality of small protrusions protruding from one side thereof. As a result, a movement resistance force is applied to the lower end surface of the photosensitive plate 16 that is moved while being attracted by the suction cups 114 and 116, and the next layer of photosensitive plate 16 that is not receiving the attraction force and is moved inadvertently. Top layer photosensitive plate 1
It can be separated from 6.

Furthermore, as shown in Figure 3, adsorption! 114.116
The distance between the separation retainer 18 and S! 1 of the width dimension of the mounting stand 14
/2 or less, and corresponds to the photosensitive plate 16 with the smallest width dimension among the plurality of types of photosensitive plates 16 used. Photosensitive plate 1 with large width dimension
In order to suction 6, more suction cups must be installed,
It is preferable to widen the spacing between the suction cups 114 and 116, but when suctioning the narrow photosensitive plate 16 on the mounting table 14, the wide photosensitive plate 16 of the next layer will also be suctioned. Therefore, adjust the suction cup 1 according to the minimum width dimension.
The standard interval is 14.116.

Further, as shown in FIG. 5, the tape 154 is attached to the suction cup 1.
It is preferable to attach this suction to the support piece 24 corresponding to the part between 14 and 116! If it is provided at a position away from between 114 and 116, it will provide resistance to the movement of the photosensitive plate 16 when the suction cups 114 and 116 move by suction.
The bending of both ends of the photosensitive plate 16 in plan view becomes large, which causes the ends with large bending to not enter into the hooks 64.

Next, the operation of this embodiment will be explained.

As shown in FIG. 2, in the initial state, the hook 64 is stopped on the side of the sprocket wheel 62 and facing the mounting table 14, and the outer chino 76 has a guide ring 84 at the forefront of the hook 64. It is arranged horizontally.

Here, a plurality of exposed photosensitive plates 16 are stacked and mounted vertically on the mounting table 14.

In the moving means 112, suction cups 114 and 116 protrude rightward in FIG. 2 by driving rotation of the motor 146 at an angle θ, and suction the vicinity of the upper end of the uppermost photosensitive plate 16 on the mounting table 14. After suction, the motor rotates by 02 degrees, the suction cups 114 and 116 return to the left direction in Figure 2, and the hook 64
The negative pressure is released above the As a result, the lower end of the uppermost photosensitive plate 16 falls into the hook 64.

The motor 78 is now driven, and the outer chino 76 is rotated counterclockwise in FIG. For this reason, the uppermost photosensitive plate 16 whose lower end is housed in the hook 64 is moved upward by the guide ring 84 sequentially moving up the photosensitive surface (the right surface in FIG. is gradually separated from the mounting table 14 from the lower part to the upper part, and is moved to the upper part of the separating support part 18, so that the anti-photosensitive surface side is brought into contact with the plurality of guide rings 46.

In this case, the lower end of the photosensitive plate 16 is accommodated in the stationary hook 64, so that the guide ring 8
The photosensitive plate 16 can be stably supported even when the photosensitive plate 4 is raised. If this hook 64 is also attached to the outer chain, that is, if the inner chain 760 is omitted, the V& Since the plate 16 must be held, the holding force of the suction cup must be increased.

When the photosensitive plate detection switch 68 guided by the guide ring 84 at the tip rises along the photosensitive surface side of the photosensitive plate 16 and detects the upper end of the photosensitive plate 16, the motor 66 is also driven and the inner check 760 moves outward. It rotates counterclockwise in FIG. 2 at the same speed as the chain 776. This causes the hook 64 to rise and lift the photosensitive plate 16.

Therefore, the guide ring 84 at the tip gradually bends the upper end of the photosensitive plate 16 in the horizontal direction along the outer guide part 80 while holding the upper end of the photosensitive plate 16 between the guide ring 46 and the holding roller 92. .94 between.

In this case, the motor 78 and the motor 66 rapidly raise the photosensitive plate 16, and when the tip of the photosensitive plate 16 reaches just before the clamping rollers 92, 94, the guide ring 84 at the tip reaches the upper limit switch 86. If detected, it is preferable to reduce the rotation speed, thereby reducing the working time. This low speed is slower than the rotational speed of the clamping rollers 92, 94 so that the leading end of the photosensitive plate 16 can be smoothly fed.

When the leading end of the photosensitive plate 16 is clamped by the clamping rollers 92 and 94, the motor 66 is reversely rotated to rotate the inner chuck 760 counterclockwise in FIG. 2, so that the hook 64 is in the state shown in FIG. Stop. The reverse rotation of the motor 66 may be started after a predetermined time delay after the upper limit switch 86 detects the guide ring 84.
6 is stopped until the rear end of the sent photosensitive plate 16 passes near the sprocket foil 56, and the rear end of the photosensitive plate 16 becomes straight due to its rigidity, and the next layer on the mounting table 14 is stopped. This prevents the problem of contact with the photosensitive plate 16. At this point, the outer check 776 is reversed and the guide ring 84 at its tip returns to the state shown in FIG. 2 in preparation for adsorption of the next layer of photosensitive plate 16. This outside Che 7
Stopping and reversing of 76 may also be started after a predetermined time delay after upper limit switch 86 detects guide ring 84.

In this way, since the hook 64 and the guide ring 84 are separately driven by the inner chain 760 and the outer chain 776, they can be driven quickly and the work cycle can be shortened. That is, the outer chain 776 and the inner chain 760 are constituted by one chain, to which the hook 64 and the connecting shaft 8 are connected.
2. If the guide ring 84 is attached together, the guide ring 84 at the tip will pass through the sprocket foil 70 portion when sending out the small photosensitive plate 16, so the small photosensitive plate 16 will be completely The chain cannot be returned to its original position until after it has been removed from the clamping rollers 92 and 94, which slows down the work cycle.

In order to make it easier to mount the photosensitive plate 16 on the mounting table 14, in FIG. A rotation axis may also be provided.

[Effects of the Invention] As explained above, the present invention provides a photosensitive plate auto feeder for feeding exposed photosensitive plates to an automatic developing machine, which is a photosensitive plate auto feeder in which a plurality of the photosensitive plates are vertically placed. a mounting table; a supporting means disposed opposite to the mounting table for supporting the lower end of the photosensitive plate; and a supporting means for supporting the lower end of the uppermost photosensitive plate among the plurality of photosensitive plates on the mounting table a moving means for moving the uppermost photosensitive plate to the mounting means; a separating means for moving the uppermost photosensitive plate away from the mounting table by moving up between the supporting means and the mounting table; and a separating means for moving the uppermost photosensitive plate away from the mounting table; It is equipped with a lifting means for feeding the top layer photosensitive plate separated from the mounting table from the upper end to the automatic developing machine, so it is an excellent product that can quickly feed the photosensitive plate to the automatic developing machine in a small installation space. have an effect.
