The inspection / cleaning line described above is constituted by, for example, an index table which rotates intermittently. Around the index table, devices for performing the operations of the above steps are arranged along the rotation direction. A plurality of plate-shaped pallets 72 as shown in FIG. 7 are attached to the outer periphery of the index table. For example, the reuse unit 71 conveyed by a belt conveyor or the like is a Pick & Place (P & P) including a robot hand or the like arranged in a reuse unit supply process.
P) The apparatus is moved from the belt conveyor onto the pallet 72 by the device, and is positioned on the pallet 72 with the front side facing upward.

The pallet 72 is formed in a plate shape. The pallet 72 has positioning pins 72 a inserted into positioning holes formed on the back side of the main body base 15 on the upper surface and inner wall surfaces of the cartridge chamber 30 and the film chamber 31. Positioning piece 72 in contact
b, 72c are formed. On the upper surface of the pallet 72, a concave portion 72d for avoiding interference with the counter plate 52 and a jig hole 72e into which various jigs are inserted are formed. A slide shaft 77 that is slidable between a position approaching the pallet 72 and a position away from the pallet 72 is attached to the lower surface of the pallet 72, and a tip of the slide shaft 77 projects toward the reuse unit 71. A holding jig 78 having a holding piece 78a is attached. The holding jig 78 is moved at two positions by a driving device provided in each step, and is used for setting the above-described light shielding cover closing mechanism to the initial position.

In the cleaning step, a static elimination air blow and air suction device are provided. This device blows off dust, dust, static electricity, and the like from the reuse unit 71 by blowing the static elimination air, and sucks the blown-off dust so as not to adhere again. The cleaned reuse unit 71 is sent to the next light shielding cover closing mechanism setting step. The light-shielding lid closing mechanism of the reuse unit 71
As shown in FIG. 8, the detection protrusion 50b of the lock lever 50 is fitted into the cam groove 42b of the cam disk 42, and the lid driving member 47 is rotated to the closed position of the light shielding lid 27 by the bias of the spring 48. Have been.

The light-shielding lid closing mechanism setting step includes a light-shielding lid and lock lever moving step and a cam member initial position setting step. The cam member initial position setting process includes:
It comprises a reduction gear positioning step and a detection gear initial position setting step. The light shielding lid and lock lever moving step includes the lock lever moving mechanism 80 and the light shielding lid moving mechanism 8.
1 and a control unit 82. The lock lever moving mechanism 80 includes a driving member 80a and a pressing member 80b. The driving member 80a includes a pressing member 80b.
Is moved between a retracted position separated from the reuse unit 71 and a pressing position where the locking lever 50 is pressed toward the locking position by contacting the locking lever 50.

The light-shielding lid moving mechanism 81 includes a lid rotating member 84,
It comprises a moving mechanism (not shown) and a rotating mechanism 85.
The lid rotating member 84 has a lever portion 4 of the lid driving member 47 at the tip.
An engagement portion 84a is provided to engage with the reset projection 74d formed on the lid 7b, and rotates the engagement portion 84a about the rotation axis of the lid driving member 47. The moving mechanism is
For example, the rotary member 84 includes a solenoid, an air cylinder, a cam mechanism, and the like. The rotating member 84 is moved between a retracted position where the engaging portion 84a is separated from the reuse unit 71 and an engaging position where the engaging portion 84a is engaged with the reset projection 47d. Move. The rotation mechanism 85 is, for example, a motor or an actuator that rotates the rotation member 84 toward the open position of the lid driving member 47.

The control unit 82 includes a lock lever pressing mechanism 8
0, and the lid drive member rotation mechanism 81 is generally controlled.
The control unit 82 drives the driving member 80a via the driver 87, and presses the lock lever 50 toward the lock position with the pressing member 80b. At the same time, the moving mechanism is operated to reset the engaging portion 84a of the rotating member 84 to the resetting projection 47d.
To drive the rotation mechanism 85 via the driver 86 to rotate the lid driving member 47 to the open position. As a result, as shown in FIG. 9, the lock lever 50 rotates to the lock position to lock the lid driving member 47 at the open position, the detection projection 50b of the lock lever 50 comes off the cam groove 42b, and the detection gear 40 and The rotation of the reduction gear 39 becomes free.

When the lock lever 50 and the lid driving member 47 are engaged, the light-shielding lid and the jig moving device provided in the lock lever moving step move the holding jig 78 attached to the pallet 72 toward the pallet 72. Move in the direction. The holding piece 78a of the holding jig 78 comes into contact with the upper surface of the lock lever 50 and enters the movement locus of the holding projection 50d. After that, in order to transport the reuse unit 71 to the next step, the lock lever moving mechanism 80 and the light shielding cover moving mechanism 81 are retracted from the reuse unit 71.
The rotation of the lock lever 50 to the release position is performed by a holding jig 78.
Therefore, the engagement between the lock lever 50 and the lid driving member 47 is maintained.

The reduction gear positioning step includes, as shown in FIG. 10, a reduction gear rotating member 89, a moving mechanism (not shown),
It comprises a rotation mechanism 90, a position detection mechanism 91, and a control unit 92. In this step, the reduction gear 39 is positioned at a predetermined position. This is a two-stage gear in which the reduction gear 39 is composed of a large gear 39a and a small gear 39b, and the large gear 39a and the small gear 39b have one tooth because the large gear 39a and the small gear 39b have different numbers of teeth. There are several combinations of rotational positions of the reduction gear 39 that mesh with the meshing position of the gear 37a and the detection gear 40, and if the positioning of the detection gear 40 is not completed, the winding completion position of the detection gear 40 may be changed. It is because they go crazy. The predetermined position of the reduction gear 39 is a rotational position one tooth before the meshing position with the detection gear 40 at the initial position.

The reduction gear rotating member 89 is connected to the hoisting knob 12.
A shaft portion 93 to be inserted into the bearing portion 34 for the drive shaft 12b, and a gear portion 94 that meshes with the large gear 39a of the reduction gear 39 when the shaft portion 93 is engaged with the bearing portion 34. ing. The gear portion 94 has four teeth arranged at four divided positions on the outer periphery, and rotates the reduction gear 39 so as not to deteriorate the elasticity of the leaf spring 44. The moving mechanism is
For example, the reduction gear rotation member 89 is constituted by a solenoid, an air cylinder, a cam mechanism, or the like, and moves between a retracted position where the reduction gear rotation member 89 is separated from the reuse unit 71 and an insertion position where the shaft 93 is inserted into the bearing portion 34. To move. The position detecting mechanism 91 is provided so as to sandwich the positioning shaft 39c of the transported reuse unit 71.

The rotation mechanism 90 is, for example, a motor or an actuator that rotates the gear portion 94 to rotate the reduction gear 39 in one direction. The position detecting mechanism 91 includes, for example, a light projecting unit 95 and a light receiving unit 96 that constitute a transmission type photoelectric sensor. The light projecting portion 95 and the light receiving portion 96 are formed in a D-shape of the positioning shaft 39c when the light projecting shaft 91a extends in a direction orthogonal to the rotation axis of the positioning shaft 39c and the reduction gear 39 is at a predetermined rotation position. The rotation position of the reduction gear 39 is detected in a non-contact manner by receiving the light emitted from the light projecting unit 95 by the light receiving unit 96.

The control section 92 operates the moving mechanism to move the reduction gear rotating member 89 to the insertion position. Then,
The rotation mechanism 90 is driven via the driver 90a, and the reduction gear rotating member 89 rotates the reduction gear 39. While the reduction gear rotating member 89 is rotating, a signal obtained from the light receiving unit 96 is monitored, and when the signal is received from the light receiving unit 96, the driving of the rotating mechanism 90 is stopped. Thereby, the detection gear 40
Since the toothless portion 40a faces the meshing position of the small gear 39b of the reduction gear 39 and the meshing of the reduction gear 39 with the small gear 39b is released, the rotation is free. The reason why the rotation of the detection gear 40 is free is that the rotation position of the detection gear 40 when the film unit 2 with the lens is recovered is other than the rotation position described with reference to FIG. This is because it is necessary to temporarily release the meshing relationship between the reduction gear 39 and the detection gear 40 in consideration of returning to the initial position.

In the detection gear initial position setting step, FIG.
2, a rack mechanism 98, a rack moving mechanism (not shown), a rotational position detecting mechanism, and a control unit 101 are provided. The rack mechanism 98 includes a rack member 102 having a rack 104 that meshes with the detection gear 40, and a drive mechanism 103 that reciprocates the rack member 102 in parallel with a pitch plane at a position where the detection gear 40 meshes. The rack moving mechanism includes, for example, a solenoid, an air cylinder, a cam mechanism, and the like. The rack member 102 and the driving mechanism 103 are retracted from the reuse unit 71 and the rack 104 of the rack member 102 meshes with the detection gear 40. The rack mechanism 98 is moved to and from the position. This movement is in a direction parallel to the rotation axis of the detection gear 40.

The rotation position detecting mechanism is, for example, a reflection type photoelectric sensor 100 and a positioning hole 40 b of the detection gear 40.
Is detected in a non-contact manner to detect whether or not the rotational position of the detection gear 40 is the initial position. The control unit 101 includes a rack mechanism 98,
The rack moving mechanism and the rotational position detecting mechanism are generally controlled. After the rack moving mechanism is operated to engage the rack 104 with the gear portion of the detecting gear 40, the driver 105
To drive the rack member 102 in one direction by a predetermined amount. As a result, the detection gear 40 rotates in the one direction by a predetermined amount, and then the rack 104 is disengaged from the gear portion of the detection gear 40, and the engagement between the rack 104 and the gear portion of the detection gear 40 is released. As a result, the detection gear 40 returns to the initial position, meshes with the reduction gear 39, and advances the reduction gear 39 by one tooth.

After the driving of the rack mechanism is completed, the control unit 1
01 receives a signal indicating that the positioning hole 40b has been detected from the photoelectric sensor 100, and confirms whether or not the detection gear 40 has returned to the initial position. In this state, the toothless portion 40a passes through the meshing position of the reduction gear 39 with the small gear 39b due to the rotation of the detection gear 40 to the initial position, and the gear portion of the detection gear 40 meshes with the small gear 39b. . As a result, the detection gear 40 returns to the initial position, and the reduction gear 3
9 also returns to the initial position.

When the detection gear 40 is positioned in the detection gear initial position setting step, the lock lever 50
The cam surface 42a of the cam disk 42 faces the detection projection 50b, and the engagement between the lock lever 50 and the lid driving member 47 is maintained. For this reason, a jig moving device is provided in the detection gear initial position setting step, and the holding jig 78 is moved to a position away from the pallet 72, and the holding jig 78 is moved.
Is released from the lock lever 50.

The inspection process of the light-shielding lid closing mechanism includes a speed reduction gear fast-forwarding process and a lid driving member operation inspection process. In these steps, the reduction gear 39 and the detection gear 40 are moved forward by an amount corresponding to the whole of the photographic film wound up in the cartridge main body 23, and whether or not the lid driving member 47 is rotated toward the closed position of the light shielding lid 27 is determined. Check if.

As shown in FIG. 12, the speed reduction gear rotating member 108, the rotation driving mechanism 109,
A moving mechanism (not shown), a rotary encoder 111, and a control unit 112 are arranged. The reduction gear rotating member 108 has a shaft portion 113 that engages with the bearing portion 34, and a gear portion 114 that meshes with the large gear 39a of the reduction gear 39 when the shaft portion 113 engages with the bearing portion 34. ,
The same one as the reduction gear rotating member 89 in the reduction gear positioning step is used. The moving mechanism includes, for example, a solenoid, an air cylinder, and a cam mechanism, and reduces the speed between a retracted position where the reduction gear rotating member 108 is separated from the reuse unit 71 and an insertion position where the shaft 113 is inserted into the bearing 34. The gear rotating member 108 is moved. The rotation drive mechanism 109 is, for example, a motor or a rotary actuator that rotates the reduction gear rotation member 108. The rotary encoder 111 detects the rotation angle of the motor 109,
A signal is sent to the control unit 112 each time the rotation angle is detected.

The control unit 112 operates the moving mechanism to move the reduction gear rotating member 108 to the insertion position, and then drives the rotation driving mechanism 109 via the driver 115,
The reduction gear 39 is rotated by the reduction gear rotating member 108.
Then, a signal obtained from the rotary encoder 111 is counted during rotation, and the rotation is performed when the count value becomes the same as the count value corresponding to the rotation amount of the winding knob 12 when the winding operation is performed to the last photographing frame. The driving of the driving mechanism 109 is stopped. Thereby, the detection gear 40
Rotates to the position where the winding operation is performed up to the last photographing frame, that is, the position one step before the winding completion position.

In the lid driving member operation inspection step, as shown in FIG. 13, the reduction gear rotating member 117 and the rotation driving mechanism 11 are used.
8, moving mechanism (not shown), operation confirmation detecting mechanism 119,
And a control unit 120. The reduction gear rotating member 117 is similar to the reduction gear rotating members 89 and 108 and has a shaft portion 121 and a gear portion 122.
The moving mechanism includes, for example, a solenoid, an air cylinder, and a cam mechanism, and reduces the speed between a retracted position where the reduction gear rotating member 117 is separated from the reuse unit 71 and an insertion position where the shaft 121 is inserted into the bearing 34. The gear rotating member 117 is moved. Further, the moving mechanism moves the operation check detection mechanism 119 between a retracted position separated from the reuse unit 71 and a detection position positioned near the reuse unit 71. The rotation drive mechanism 118 is, for example, a motor or a rotary actuator that rotates the reduction gear rotation member 117.

The operation confirmation detection mechanism 119 includes a substantially L-shaped detection piece 124 and a photoelectric sensor 125. The detection piece 124 is rotatable around a rotation shaft 128 provided between one end 126 and the other end 127, and is held in a predetermined posture by a spring 129, a stopper 130, and the like. When the detecting piece 124 is moved to the detecting position by the moving mechanism, one end 126 is fixed to the lock lever 50.
Abut. The photoelectric sensor 125 is arranged at a position facing the rotation locus of the other end 127. As a result, when the lock lever 50 rotates to the unlock position, the detection piece 1
24 rotates counterclockwise by the bias of the spring 129,
At this time, the other end 127 of the detection piece 124 is
The operation of the lock lever 50 is confirmed.

The control unit 120 operates the moving mechanism to move the reduction gear rotating member 117 to the insertion position, and at the same time, moves the operation confirmation detection mechanism 119 to the detection position. Thereafter, the rotation drive mechanism 118 is driven by a predetermined amount, and the reduction gear 39 is rotated by a film winding operation for winding all of the photographic film 24 into the cartridge body 23 after photographing the last photographing frame. As a result, FIG.
As shown in (2), the detection gear 40 is rotated to the position when the photographic film 24 is completely wound into the cartridge body 23. At this time, the cam groove 42b of the cam disk 42 faces the detection protrusion 50b of the lock lever 50, and the lock lever 50 is clockwise around the shaft 50c by the bias of the spring 48 via the lid driving member 47. It turns to move to the unlock position. The lid driving member 47 is unlocked by the lock lever 50 and the light-shielding lid 2 is
7 toward the closed position.

The control unit 120 monitors a signal obtained from the photoelectric sensor 125 while driving the rotation drive mechanism 118. When the lock lever 50 moves to the lock release position, the one end 126 of the detection piece 124 is pressed by the lock lever 50, and thus rotates counterclockwise against the bias of the spring 129. Thereby, the other end 127 is connected to the photoelectric sensor 125.
And the detection signal is input to the control unit 120. The control unit 120 closes the lid driving member 47 by receiving or not receiving a detection signal within a predetermined time period after driving is stopped after driving the rotation driving mechanism 118 and then performing rotation corresponding to film winding. It is determined whether the rotation operation to the position is OK. When the rotation of the lid driving member 47 is identified as NG, the control unit 120 sends the identification data to the control unit in the NG product discharging process.

FIG. 7 shows the resetting process of the light shielding cover closing mechanism.
-The light-shielding lid and the lock lever moving step described in FIG.
The same steps, mechanisms, and devices as the reduction gear positioning step and the detection gear initial position setting step are arranged, and the light shielding lid closing mechanism is reset to the initial position again by these.

As shown in FIG. 15, an image pickup section 135, an illumination section 136, an image processing section 137, a comparison section 138, a RAM 139, and a determination section 140 are provided in the step of inspecting the reduction gear leaf spring set. I have. The illumination unit 136 uses, for example, a plurality of fiber illuminators that guide the halogen light with an optical fiber and illuminate the light with a small-diameter light beam, and diffusely illuminate the elastic piece 44a of the leaf spring 44 of the reuse unit 71 with them. The imaging unit 135 includes a magnifying lens 135a, a CCD camera 135b, and the like. The imaging unit 135 magnifies the light reflected by the elastic piece 44a in a direction orthogonal to the direction in which the elastic piece 44a elastically deforms. Image processing unit 1
Reference numeral 37 denotes a binarized captured image, which is displayed on a monitor, and which is displayed in a specific range of the monitor screen, for example, in a range where the elastic piece 44a is positioned when the image is not slouched.
A window W as shown in (A) is provided, and a white pixel area in the window W is obtained. The elastic piece 44a of the leaf spring 44 of the present embodiment is provided with a reinforcing piece bent in an L-shape in a direction orthogonal to the elastic deformation 44a. The imaging means 135 images light reflected on the plane of the reinforcing piece.

The comparing section 138 calculates the white pixel area thus obtained,
The reference pixel area is compared with a reference pixel area stored in the RAM 139 in advance. Since the leaf spring 44 is made of a copper material, when it is illuminated with halogen light, the reflected light is captured as a white bright image. When the leaf spring 44 is slack, it comes off the window W, and the number of white pixels in the window W decreases. Judgment unit 1
40 determines whether or not the leaf spring 44 can be used based on the comparison result obtained by the comparison unit 138. For example, if the obtained white pixel area determines a threshold value with respect to a reference white pixel area, and the threshold value is, for example, 50%, it can be used if it is 50% or more as shown in FIG. If it is 50% or less as shown in FIG. When the plate valve 44 is determined to be an NG product, the determination unit 140 sends the determination data to the control unit of the NG product discharge process.

Instead of providing a window at a specific position on the monitor screen and performing an inspection based on the number of white or black images in the provided window, a feature is extracted from an image obtained by capturing a leaf spring. The use of a leaf spring may be determined using a feature extraction method of comparing this value with a reference place, or a pattern matching method of superimposing predetermined data and a captured image in a memory.

The reuse unit 71 which has completed the steps of setting, inspecting and resetting the light shielding cover closing mechanism is conveyed to the finder lens cleaning step by rotating the index table. As a method of cleaning the finder lens 32,
First, dust and dirt adhering to the photographing lens 32 are blown off by air blow, then a cleaning liquid is adhered to the surface of the finder lens 32, and finally, the surface of the finder lens 32 is polished by a cleaning tape.

It is arranged obliquely with respect to the reuse unit 71 so that b can be rotated. The drive unit 188 moves the holding member 189 between an operating position where the holding member 189 approaches the reuse unit 71 and a retracted position away from the reuse unit 71. The plunger 188a is retracted into the driving unit 188 by the bias of the spring when not operating, and when the driving unit 188 is driven by the control unit 178 via the driver 191, the plunger 188a is driven against the bias of the spring. It protrudes from the portion 188.

When the drive unit 179 is driven by the control unit 178, the holding plate 180 moves toward the upper operation position, and the large-tooth feed lever 181 and the small-tooth feed jig 190 are used for the jig for the pallet 72. Insert into the hole 72e. FIG.

The small-tooth feed jig 190 presses the large-tooth feed lever 181 at its tip. Large tooth feed lever 1
81 is rotated against the bias of the spring in the direction in which the pressing portion 181b moves away from the sprocket 61.

As a result, as shown in FIG. 25, the large teeth 61a protrude from the film rail surface 29c, and the shutter driving lever 54 and the locking lever 53 are rotated by the cam member 55 to charge the shutter. Will be The large teeth 6 protruding from the film rail surface 29c.
Since 1a is stored in the notch 190b of the small tooth feeding jig 190, the small tooth feeding jig 190 does not interfere with the large teeth 61a. Further, the counter driving unit 5 of the cam member 55
5a rotates the counter plate 52 by one division using the locking gear 52a and the stepping gear 63a. This allows
The counter plate 52 has an indicator 67 as shown in FIG.
It is set to the initial position where the mark A matches b. When the large tooth feed lever 181 and the small tooth feed jig 190 return to the retracted position, they do not interfere with the sprocket 61.

After the sprocket feed step, a re-shutter release step having the same configuration as the above-described shutter release step is arranged. The shutter release is performed by forcible rotation of the locking lever 53, and the shutter mechanism is released. Is initially set. In the re-shutter release step, the swing of the shutter blade 58 may be detected by a photoelectric sensor to check whether the shutter is released at an appropriate speed and opening amount.

After the initial setting of the film counting mechanism is completed, the reuse unit 71 is transported to the next inspection step of the film counting mechanism. This inspection step includes, as shown in FIGS. 26 and 27, a reflective photoelectric sensor 194,
The meshing state inspection mechanism 195 and the meshing state inspection mechanism 19
5 and a control unit 196 for controlling these. The moving mechanism moves the meshing state inspection mechanism 195 between a retracted position away from the reuse unit 71 and an operation position close to the reuse unit 71.

The control unit 196 detects the rotation position of the counter plate 52 by the photoelectric sensor 194. Photoelectric sensor 19
4 is the same as the photoelectric sensor 160 in the counter feeding step, and detects the detection opening 51 a of the counter plate 52 via the opening 67 d of the top plate 67. Photoelectric sensor 194
Detects the detection opening 51a, a detection signal is input to the control unit 161. When the detection signal is not input, the control unit 196 determines that the inspected reuse unit 71 is N

98a is retracted into the drive section 198 by the bias of the spring when not operating, and when the drive section 198 is driven, the plunger 198a is protruded with a predetermined pressing force P against the bias of the spring.

When the engagement state inspection mechanism 195 is moved to the operating position by the moving mechanism, the engagement piece 199a formed at the end of the pressing jig 199 comes into contact with the locking gear 25a.
When the control unit 196 drives the driving unit 198 via the driver 202, the plunger 198a protrudes leftward in the drawing with a predetermined pressing force P, and presses the locking gear 25a by the engaging piece 199a. The pressing force P is a pressing force that cannot rotate the counter plate 25 when the locking gear 25a and the stepping gear 63a and the locking cam 55g and the driving gear 55h are properly engaged. . Therefore, when the counter plate 25 is rotated by the pressing force P, the locking gear 25
a, the stepping gear 63a, the locking cam 55g, and the driving gear 5
It can be determined that the meshing state with 5h is poor. When the counter plate 25 is rotated by the pressing force P, the protrusion 199b provided on the pressing jig 199 is connected to the detection switch 2.
00, the detection switch 200 inputs a detection signal to the control unit 196. The control unit 196 controls the detection switch 20
When a detection signal is input from 0, the reuse unit 71 that has been inspected is identified as an NG product, and this identification data is
It is sent to the control unit of the G product discharging process.

After the inspection of the film counting mechanism is completed, the reuse unit 71 is transported to an NG product discharging step.
In the NG product discharging process, the reuse unit 71 identified as an NG product in each inspection process is lifted from the pallet 72 by a P & P device including a robot hand or the like, and is collected on a collection tray. The reuse units 71 accumulated on the collection tray are conveyed to a reuse unit disassembly line, disassembled for each part, and then recycled as raw materials.

In the next reuse unit transfer step, the light shielding cover closing mechanism and the film counting mechanism are reset, and
The reuse unit 71 that has passed various inspections is lifted from above the pallet 72 by the P & P device, and is transferred to a belt conveyor connected to an assembly line of the lens-fitted film unit. The reuse unit 71 transported to the assembly line is reused as a component of a new film unit with a lens.

The pallet 72 from which the reuse unit 71 has been removed is transported to the next pallet cleaning step. The pallet 72 removes dust and dirt from the reuse unit 71 by static elimination air blow and air suction, and mounts a new reuse unit 71 in the reuse unit supply process again.

In the above embodiment, the lens-fitted film unit is used for the inspection for reuse. However, a new lens-fitted film unit can be used for the inspection at the time of assembly. Also, as a light-shielding lid closing mechanism,
In the above embodiment, the film transfer amount is measured from the rotation amount of the spool. However, the present invention is not limited to this, and the film transfer amount may be measured from the count amount of the film count mechanism or the rotation amount of the sprocket.
