Description Inspection method of used photo patrone and

Method of reuse and method of producing photographic film

The present invention relates to a method for inspecting a used photo cartridge and an inspection system thereof, and more particularly, to a method and an inspection system for non-destructively inspecting a used photo cartridge without disassembling.

Further, the present invention relates to a method for manufacturing a photographic film, and more particularly, to a photographic film in which a photographic film is locked and wound around a photographic cartridge having a built-in spool and both sides shielded by a cap. And a method for producing the same.

Furthermore, the present invention relates to a method for reusing a photo patrol port and a system for reusing a photo patrone. More specifically, the present invention relates to a photo patrol port without disassembling the photo patrol port at all. The present invention relates to a method for reusing a photographic patrone and a system for reusing a photographic patrone that can remove a tail end of a film locked in the photographic cartridge and lock a new tail end of the film. Landscape: technology

Conventionally, used photographic patrones whose photographic film has been developed in a lab are either collected as garbage and processed as fuel for heat sources directly, or are ground and separated into metals and resins and then used as resources. They have been recycled or landfilled as industrial waste, but in recent years the reuse of used photographic patrones has been Power, etc. has begun to attract attention, and concrete studies have been made on higher-order reuse (reuse), and there is a demand from the market.

However, regarding the reuse of photographic patrones, it has been disclosed in Japanese Patent Application Laid-Open No. 2001-337374 that only the spool is reused after removing the spool from the patrone body. No consideration is given to the reuse of the entire photographic port, including the spool. In this prior art, since the photo cartridge is disassembled and only the spool is reused, the main body of the cartridge other than the spool becomes garbage and is not considered environmentally friendly.

For this reason, the applicant of the present invention has applied a method and a system in which the photographic patrone can be reused without disassembling it with maximum consideration for environmental suitability.

0 3 0 is proposed.

In this technology, a part of the tail end of a photographic film that has been cut near a slit opening and locked to a spool in a used photographic door (hereinafter referred to as a tail end film). Using this tail-end film as a guide, insert a thin plate jig from the slit opening, remove the tail-end film from the spool with this jig, and then insert the jig into this jig. With the tool as a guide, a new unexposed film is inserted from the slit opening, locked on the spool, and then rolled up with the unexposed film.

If the used photo cartridge is reused without disassembly without disassembly, the photo cartridge will use the used product as it is. In order to maintain the quality of the unexposed film (with the unexposed film entangled in the photographic cartridge), the unexposed film must be wrapped in the photographic cartridge before reuse. The patrone itself is scratched, deformed, and leaked light It is necessary to inspect whether there is any defect such as the power, that is, whether the photo door is reusable. In this case, in order to re-use the photographic patrone without disassembling it in consideration of environmental suitability, this inspection also requires the entire photographic patrone from outside to inside without disassembling the photographic patrone. Inspection by destruction is required.

Therefore, the first object of the present invention is to realize recycling production with minimum waste by maximizing environmental suitability and inspecting photographic patrone without decomposing it without decomposing it. An object of the present invention is to provide an inspection method and an inspection system for a photographic patrone that can be used.

Conventionally, the production of photographic film, in which a photographic film of 35 mm or the like is wound and housed in a patrone, is generally performed by stamping and bending steel plates, rolling a boat with telemps, and rolling the steel plate. A patrone with a cap fitted on only one side is formed, and a film scroll (a film wrapped around a spool) is accommodated in this pat opening, and then the other side of the pat opening is placed. This was done by fitting a cap.

However, in this case, the patrone in which the cap is fitted on only one side tends to expand due to the elasticity of the steel plate on the other side where the cap is not fitted, so the shape variation is large due to the characteristic variations such as the hardness of the steel plate. In many cases, when a film was rolled in or when handling such a patrone in a single-cap state, there were many problems such as poor positioning of the mouth of the pat and the wrong check.

As a technique for solving such a problem, there is a method in which a film is locked and wound around a patrone having a built-in spool and a stable shape covered on both sides with caps. For example, Japanese Patent Laid-Open No. 49-107732 discloses a spool built in and caps on both sides. By inserting a leaf spring with a high elastic coefficient that has been processed so that the tip is curved in advance from the slit slot of the patrone in the fitted state, the tip of the leaf spring that has passed through the slit is bent into a curved shape by its elasticity. Then, the film is inserted into the slit spring along the inside of the plate spring to lock the film on the spool. After that, the leaf spring is removed from the slit opening and the film is wound. The method of taking is disclosed.

However, since this leaf spring is linearly inserted into the cartridge of the cartridge from the receiving conduit that receives the leaf spring, the tip of the leaf spring, which has been preliminarily formed into a curved shape, and the slit opening are formed.揷 When the leaf spring exits the receiving conduit and passes through the linear slit slot of the patrone, the tip of the leaf spring is inserted into the slot while interfering with the inner surface of the slit slot as an elastic curve. As a result, there was a problem that the telem attached to the inner surface of the slitlot was worn, and sometimes the slitlot was deformed. For the production of photographic films, the abrasion of telempe ゃ the deformation of slit slits is a serious problem that affects the light-shielding properties of the gate opening.

In addition, the leaf spring is formed into a curved shape at the tip by a member having a high elastic modulus, so the shape is not stable, and the tip may not reach the target position, that is, the film locking portion of the spool. There was also a problem that the reliability of the locking was reduced.

Accordingly, a second object of the present invention is to solve the above-mentioned problems, to provide a built-in spool, and to apply a film from the outside of the cartridge to a stable photographic cartridge with both sides shielded by a cap. It is an object of the present invention to provide a method of manufacturing a photographic film that can be locked and wound and that can be locked without damaging a patrone's slit opening or telemp.

In addition, conventionally used 135 type photographic patrones (hereinafter simply referred to as T JP03 / 07144

May be called patrone. As a method of using), use a mating type patrone that can easily remove the cap, cut the long film with scissors, etc., lock the film with adhesive tape, wrap the film around the spool, and then open the Only a small number of users have used a refill method that puts the cap into the bag and fits the cap by hand.

However, in recent years, most of the pat mouths have a cap-clamping type that makes it difficult to remove the cap in order to further enhance the light-shielding properties, and a method that does not use an adhesive tape to lock the film and the spool. Is becoming mainstream. For this reason, it is difficult to rewind the film by winding it on a spool, and the patrone developed in the lab is rarely used again and is discarded as it is, causing environmental problems.

There is also a method in which the patrone is disassembled to separate only the spool, and this spool is crushed, then pelletized, and reused.However, the main part of the pat mouth other than the spool becomes garbage. There is no change, and they do not solve the problem of waste in large quantities.

Furthermore, Japanese Patent Application Laid-Open No. 2001-337374 proposes a method of disassembling a pat mouth, taking out a spool therefrom, and reusing only this spool. Even the body of the pachinko mouth other than the spool becomes garbage.

Therefore, it is desired to establish a method and a system that can re-use patrone without decomposing it.

On the other hand, the film tail end and the spool are generally locked by engaging an engagement hole formed on the film tail end side with a locking claw formed in a slit of the spool. I have. For this reason, in order to remove the old film from the spool and attach the unexposed new film to the spool, the two can be easily disengaged or engaged. It is desired to stop.

Focusing on the method of locking the film tail end to the spool, conventionally, a curved leaf spring was inserted from the pat opening and the slit opening in Japanese Patent Application Laid-Open No. 497-10732, and this was used as a guide. A method for inserting a film and locking the film to a spool is disclosed. However, since the panel panel is curved, there is a drawback that the slits in the gate opening, particularly the telem provided to make the slit holes light-shielding, are easily damaged.

Also, Japanese Patent Application Laid-Open No. 51-136642 discloses that after joining the leading end of a film to a strip (leader) having one end connected to a spool and the other end exposed from a patrone slit opening, A method of winding a film on a spool is disclosed. However, when the leader and the film are joined, a step is likely to occur at the joint due to a difference in thickness or misalignment of the butt, etc.When the film is wound around the outside, the step is transferred and streaks are formed in the film. In the worst case, There is a problem that force filing occurs.

Further, in Japanese Patent Application Laid-Open No. 52-77772, a flexible guide strip (leader) is attached to the spool, and one of the spools is attached to the patrol mouth with the one protruding outside the patrone, and is placed along the leader. A method is disclosed in which a film is inserted and locked on a spool, and wound around a film together with a leader. However, since the film is rolled up together with the leader, there is a problem that the leader easily jams at the slit opening of the cartridge when feeding the film. Also, if the leader is put through the processor with the slit coming out of the slit, when the tail end of the film is cut with force, the film and the leader will be overlapped and cut. Wear may also occur.

Japanese Patent No. 2967790 describes a patrone composed of two resin case parts, in which the film guide means is integrally formed with the spool so that the boundary with the spool becomes thin. , With one end of the film guide protruding from the film entrance A method is disclosed in which after the film is locked on the spool along the film guide means, the film guide means is separated and the film is wound. However, when the film guide means is separated (teared), powder and dust are easily generated, and there is a problem that the film adheres to the film and causes harm.

In addition, none of these methods is related to the locking of the film, and does not mention the technology of separating the tail end of the film from the used pato mouth.

Patent No. 3 036 715 discloses that in an APS cartridge, a locking hole at the leading end of a film is captured by an arc-shaped jig made of a thin metal plate, and force is applied through a cartridge slit slot.

—Insert the film into the spool slit so that it does not interfere with the cartridge, and lock the film.Insert a jig made of a thin metal plate through the slit slot of the cartridge up to the spool so that it does not interfere with the cartridge. A method is disclosed in which the film is lifted from the locking claws to remove the film.

However, it can be used for cartridges (APS) whose shape is designed so that the arc-shaped jig does not interfere with the slits of the force cartridge. However, in the case of the 135 cartridge, an arc-shaped jig made of a thin metal plate It cannot be used because it interferes with the slit part of one and deforms it. Also, the tip of the locking jig must escape the locking hole of the film in order to hook the locking hole of the film with the locking claw of the spool, while the jig for removing the tail end is locked. In order to lift the film from the pawl, a part corresponding to the spool pawl is required. For this reason, the two jigs are not the same but are separate products, so that there is a problem that the process is divided and the cost is increased.

Accordingly, a third object of the present invention is to provide a photo pat mouth which can greatly reduce trash by reusing a used pat mouth which has been conventionally garbage without disassembling it. And a reuse system. PC so-called picture 44

Hereinafter, an embodiment for achieving the first object of the present invention will be described. First, the configuration of the photo patrol door (hereinafter simply referred to as patrone) will be described. Fig. 1) is a cross-sectional view showing the internal structure of the gate opening, Fig. 1 (b) is a side view of Fig. 1 (a) viewed from the direction I, and Fig. 2 is Fig. 1 (b). Fig. 3 is a side view of the patrone viewed from the II direction, and Fig. 3 is a perspective view of the used patrone. Here, the most representative 135mm film pocket for storing 35mm photographic film is shown. The patrone 1 is configured such that a spool 1B is built in a patrone body 1A formed into a cylindrical shape using a steel plate, and caps a1 and a1 are caulked and fixed to both sides thereof. An opening a2 is formed at the center of each cap a1, and each hub 1 and b2 of the spool 1B projecting from both ends thereof are supported by projecting from the opening a2 to the outside. Thus, it is rotatable in the nose cone 1A. The gate opening body 1A is formed by overlapping the inner surfaces of both ends of a steel plate rolled into a cylindrical shape with a gap therebetween, bending the overlapped portion in the same direction, and in the circumferential direction of the gate opening 1 body 1A. A photographic film (not shown) that extends and forms a gap in the overlapping portion Picture 44

In the spool 1B, flanges b3 and b3 are provided at both ends of a take-up shaft b2 for winding a photographic film, and eight b1 and b2 are provided concentrically outside thereof. The hubs b 1 and b 2 are built into the patrone main unit 1 A, and the protruding side hub b 1 that protrudes greatly from the pat door main unit 1 A and the non-projecting that does not protrude from the patrone main unit 1 A Hereafter, in the present specification, the former protruding side hub b1 is referred to as a long hub, and the latter non-protruding side hub b2 is referred to as a short hub.

A slit-shaped spool hole b4 into which the leading end of the photographic film is inserted is formed in the take-up shaft b2, and a locking claw b5 and a locking claw b5 are locked in the spool hole b4. A holding rib b6 for preventing the photographic film from coming off is provided in an opposed shape. In the embodiment shown in FIG. 1, two locking claws b5 are provided at predetermined intervals in the spool hole b4, and only one pressing rib b6 is provided therebetween. The number and shape of 5 and the holding rib b 6 are not particularly limited.

As shown in Fig. 2, the DX Percode a5 for identifying the type and sensitivity of photographic film stored in the patrone, the type of manufacturer, etc. Conductive part with exposed metal background and painted insulating part are provided in a checkered pattern on the surface of the main body 1A, and the type of photographic film, such as sensitivity and number of photographic films, stored inside is arranged by the arrangement pattern.

In addition, the patrol mouth 1 shown in the figure is provided with a bar code a7 for product identification that is unique to the Konica Patrone, in addition to the DX bar code a5 and the CAS code a6. 44

15 As shown in Fig. 3, the used pawl 1 is cut off near slit a3 with the photographic film locked on the spool, and a part of the tail end film F is cut off. It is in a state of protruding from slit opening a3. In the present invention, when a new unexposed film is loaded into such used patrone 1 and reused, the used patrone 1 is inspected.

Next, an inspection method and an inspection system according to the present invention will be described. FIG. 4 is a process block diagram showing a flow of an inspection method according to the present invention, and FIG. 5 is a schematic configuration diagram of an inspection system.

In the present invention, as shown in FIG. 4, the inspection step includes an alignment and positioning step 100, a sorting step 200, an appearance inspection step 300, an internal inspection step 400, and a recovery step 500. It is configured. The order of the appearance inspection step 300 and the internal inspection step 400 is not particularly limited. Hereinafter, the details of each inspection process will be described with reference to the configuration of the patrone shown in FIGS. 1 (a) to 3 and the schematic configuration diagram of the inspection system shown in FIG.

(1) Alignment positioning process

The used patrone 1 collected from the laboratory is transported to the main inspection step in a state of being stored in a container 10 such as a hopper. In the alignment and positioning process 100, prior to the inspection, the cartridges 1 are aligned in the axial direction of their spools 1B so that each cartridge 1 can be easily inspected, and the slits a3 of each cartridge 1 are all in the same position. Perform positioning so that

The alignment and positioning step 100 shown in the present embodiment includes an axial alignment and transport step 101 and a rotational direction positioning step 102. First, in the axial alignment and transport step 101, a part feeder (not shown) The spool 1B is aligned in the axial direction at the patrol port 1 using an appropriate alignment supply device. The aligned patrone 1 is then rotated In the placement step 102, as shown in FIG. 6, they are individually stored in buckets 20, respectively. A plurality of buckets 20 are mounted on the conveyor BC and are configured to accommodate most of the cartridge 1 except for the slit port a3, and the cartridge 1 is attached to the spool 1B in the bucket 20. By rotating about the axis, the slit port a 3 comes into contact with the upper edge 20 a of the bucket 20, and the direction of the slit port a 3 is fixed at that position, and the slit port a 3 of the patrone 1 is fixed. Are positioned so that they all face the same side. Each of the cartridges 1 positioned in this manner is transported to the next step by driving the transport conveyor BC while being stored in the bucket 20.

(2) Sorting process

The patrone 1 aligned and positioned in the alignment and positioning step 100 is sent to a separation step 200, where it is separated into a conforming product and a non-conforming product prior to inspection. The classification of conforming products and non-conforming products here means that the patrone is sieved in advance before executing the subsequent inspection items, for example, when the patrol port 1 is a product of another company. This can be performed by reading the DX bar code a5 provided on the surface of the tablet 1.

The DX bar code a5 is a standardized information code common to all companies, and as shown in FIG. 6, the reading window 21 formed in the bucket 20 is stored in the bucket 20. The DX barcode a5 on the patrone 1 surface is exposed to the outside. By reading this DX barcode using a barcode reader 30, it is possible to automatically identify the type of product, such as a product of its own or a product of another company. In addition, the type of photographic film stored in the patrone 1, for example, color, black and white, sepia, reversal, etc., may be determined, and accordingly, a conforming product and a non-conforming product may be separated. It is also preferable to discriminate at this stage even the reading error of the DX code a5. A switching gate 31 is provided on the transport path in the separation step 200, and the patrone 1 that has passed through the separation step 200 is pushed out of the bucket 20 by a pusher (not shown) in the axial direction and switched. Transferred to gate 31. Here, the non-conforming product based on the information read by the barcode reader ₃₀ is discharged out of the process, and only the conforming product is transferred to the next process.

According to the present invention, when reusing a patrol mouth when collecting a production loss product generated in the process of manufacturing a patrone or an expired product expired in a store or the like, the switching gate 31 is used for the re-use. It can be joined to the inspection process. The above-mentioned lost or expired patrone 1a collected from factories and stores is cut off before merging because it contains unused photo film Fa. For this reason, the film cartridges of the recovered production loss products and expired products are cut in the film feeding and cutting step 600.

In the film feeding and cutting step 600, as shown in FIG. 7, a pair of feeding rollers 1 1, which sandwiches and feeds the unused photographic film Fa stored in the patrol opening 1 a, is used. , 11 and a cutter 12 for cutting the fed photographic film Fa near the slittro of the cartridge 1a. At this point, the collected film 1a is fed by the feeding rollers 11 and 11 and the photographic film Fa is fed by the rollers 11 and cut by the cutter 12 so that only the tail end film remains. . Thereafter, the patrone 1a is joined from the switching gate 31 to perform an inspection similarly to the used patrone 1 collected from the laboratory.

In the following, the patrol port of the production loss product or expired product merged from the switching gate 31 is also referred to as “patrone 1”.

(3) Visual inspection process The compliant patrone 1 that passed the separation process 200 is sent to the next appearance inspection process 300, where the patrone 1 is inspected for its appearance without being disassembled. The appearance inspection process 300 shown in the present embodiment includes a tail edge film presence inspection process 301, a slit opening deformation inspection process 302, an overall height inspection process 303, an outer peripheral deformation inspection process 304, and a CAS pattern. It is configured to include a one-step detection step 305. Note that the order of these steps 301 to 305 is arbitrary.

Each of the above steps 301 to 305 is arranged at a predetermined position on a rotatable inspection tray 40. After passing through the sorting step 200, the patrol machine 1 is pushed out of the switching gate 31 in the axial direction by a pusher (not shown), and is transferred to the inspection pallet 40 to hold the pawl opening 1. It is transferred to the attached holding means 80.

As shown in FIG. 12, the holding means 80 is attached to the surface of the inspection turret 40, and has a housing 81 for housing the patrone 1 and a shaft with respect to the housing 81. And an opening / closing section 83 provided so as to be openable / closable centered at 82. The opening 1 is housed in the housing 81 from the opened opening / closing section 83 with the slit a3 facing the opposite side to the shaft section 82, and then the opening / closing section 83 Is closed, so that the slit slot a 3 is exposed to the outside from the holding means 80 while being sandwiched between the edge of the housing portion 81 and the edge of the opening / closing portion 83. . The patrone 1 is held by the holding means 80 and conveyed between the above-described steps by the rotation of the detection turret 40.

The patrone 1 transferred from the switching gate 31 to the holding means 80 is subjected to the first trailing edge film presence / absence inspection step 301 by rotating the detection turret 40 clockwise.

In the tail end film presence inspection step 301, the presence or absence of the tail end film F is inspected. Previous Four

19 As described above, when the unexposed film is to be locked to the spool 1B of the patrone 1 using the tail end film F, the tail end film F is necessary. As shown in Fig. 3, the tail end film F is cut off near the slit slot a3 of the patrone 1, so that the tail end film F is entangled in the pat slot 1 in the process of being transported to the main inspection step. It may be rare. Therefore, before inspecting the presence or absence of the tail end film F, slightly rotate the spool 1B in the film unwinding direction so that the tail end film F can be taken out of the cartridge 1 from the slit opening a3. deep. Therefore, as shown in Fig. 5, before the inspection of the presence or absence of the tail end film F in the upstream process of the tail end film presence inspection process 301 or at least before the inspection of the tail end film F It is preferable to have a film unwinding step 301a in which the spool 1B is rotated to take out the tail end film F from the slit slot a3.

In the film unwinding step 301a, as shown in FIG. 8, a spool rotating means having a rotating shaft 41 for inserting the spool 1B into the short hub b2 side and rotating the spool 1B. By rotating the rotating shaft 41 in the spool 1B in the unwinding direction of the tail end film F by the spool turning means, the tail end film F is moved out of the slit roller a3. I'm out. In order to prevent excessive rotation of the spool 1B at this time, a torque detecting means 42 such as a torque meter or a torque limiter for detecting the torque at the time of rotation of the rotating shaft 41 is provided. The rotation is stopped.

Further, as shown in FIGS. 1 (a) and 1 (b), ribs b7, b8 are provided in a single character inside the hubs b1, b2 of the spool 1B. Using the direction of the rib b7 or b8, it is also possible to detect excessive rotation of the spool 1B. That is, since the direction of the opening of the spool hole b4 in which the tail end film F is locked can be known from the direction of the ribs b7 and b8, the rib b7, b 8 direction 7144

20 phase (phase) is detected, and the phase of the spool 1B when the tail end film F is completely discharged from the direction of the rib b7 or b8 is detected, and the spool 1B is detected at that phase. The rotation of the rotation shaft 41 may be controlled so as to stop. Since the orientations of the ribs b7 and b8 differ depending on the manufacturer of the patrone 1, the results of reading the DX barcode using the barcode 30 in the sorting step 200 are stored. Here, based on the maker information of the read result, the position of the ribs b7 and b8 of the spool 1B when the tail end film F is completely discharged for each patrone 1 may be determined and switched. preferable.

In each of the subsequent steps, the phase of the spool 1B is fixed as appropriate so that the tail end film F is not re-engaged in the cartridge 1 while the cartridge 1 is being conveyed in the process. It is preferable to keep it fixed by using a means.

In the tail end film presence / absence inspection step 301, a tail end film detecting means 43 comprising an optical detection device such as a photoelectric sensor is disposed near the slit a3 of the patrone 1. After unwinding the film F, the tail-end film detecting means 43 automatically detects whether the tail-end film F is coming out of the patrol opening 1 or not. Here, products that are not exposed at the tail end film F where the tail end film F is not detected are to be discharged out of the process as NG products.

The pawl opening 1 where the presence of the tail end film F is confirmed is sent to the slit opening deformation inspection process 302 by rotation of the inspection let 40. In this slit opening deformation inspection step 302, a displacement gauge 44 is arranged near the slit opening a3 of the patrone 1, and it is inspected whether the slit opening a3 is deformed. The displacement meter 4 4 may be either a contact type or a non-contact type. Patrones whose slit slit a3 is deformed and non-standard sized products are to be discharged out of the process as NG products. The patrone 1 that has passed the deformation inspection of the slit a3 is sent to the full height inspection process 303 by rotating the inspection turret 40. In the whole height inspection step 303, a displacement meter 45 is arranged close to the patrone 1, and the whole height of the patrone 1 is inspected by the displacement meter 45. The displacement meter 45 may be either a contact type or a non-contact type. The displacement meter 45 inspects whether the cap a2 is not lifted up and whether the patrone 1 has been crushed, and discharges nonconforming products out of the process as NG products. Products to be released.

The patrol mouth 1 that has passed the height inspection is sent to the outer peripheral deformation inspection process 304 by rotation of the inspection let 40. In the outer peripheral deformation inspection step 304, the surface of the gate opening 1 is inspected. Here, an image recognition means 46 such as a CCD camera is arranged close to the gate 1 so that the entire periphery of the gate 1 is image-recognized and stored in advance. By comparing with the reference image, it is possible to inspect whether or not there is a deformation such as a dent on the surface of the Patrone 1 and whether or not there is a flaw. Further, a laser displacement meter may be used to detect the entire circumference of the surface of the gate 1. Here, products that do not conform to the inspection are to be discharged as NG products out of the process.

The pawl opening 1 that has passed the outer peripheral deformation inspection is sent to the CAS pattern inspection step 305 by rotating the inspection turret 40. In the CAS pattern detection step 304, the conductive insulation pattern of the CAS code a6 provided on the surface of the cartridge 1 is checked using the stylus probe 47a. As shown in FIG. 12, a reading window 84 for reading the CAS code a 6 is formed in the holding means 80 for holding the cartridge 1 being conveyed, and the reading window 84 is formed from the reading window 84. The CAS code a6 of Patrone 1 is exposed. As shown in the same figure, the stylus probe 47a abuts by moving forward from the reading window 84 toward the CAS code a6, and reads the code information. The CAS code a6 records type discrimination information such as the sensitivity and number of sheets of photographic film stored in the camera. A melody loaded with a patrone detects this CAS code a6 By doing so, information such as the sensitivity and the number of photographic films can be obtained automatically. Therefore, the unexposed film newly stored in the patrone 1 also needs to have the same sensitivity and number of sheets as those recorded in the CAS code a6. By reading the code a6, the result of the reading is separately stored so that the type of the port 1 can be used when the unexposed film is locked in the subsequent process.

In addition, when a code for identifying the type is provided separately from the CAS code a6, as in the case of a Konica Pato mouth, the reading window 84 is provided with the barcode for identifying the type. The bar code a 7 may also be formed so as to be readable, and the bar code a 7 may be read using a bar code reader 47 b. In the case where the CAS pattern a6 or the barcode a7 for product type identification fails in the CAS pattern inspection step 305, the product is to be discharged out of the process as an NG product.

After the completion of the CAS pattern inspection 305, the inspection turret 40 rotates to a transfer position where the compliant cartridge 1 is transferred to the next process and stops. At the delivery position, a delivery turret 50 is provided, and a pat port 1 of a conforming product in each of the above steps is received from the inspection turret 40, and the next internal inspection step 40 is performed by rotating at a predetermined angle. Transfer to 0.

In this case, the products to be discharged in each of the above steps are discharged from the inspection turret 40 at a position where the inspection turret 40 is further rotated. It may be discharged from the inspection turret 40 each time it is determined. (4) Internal inspection process

The patrone 1 that has passed the visual inspection process 300 is subjected to internal inspection by rotating the inspection turret 60 disposed adjacent to the delivery evening let 50 via the delivery evening let 50. It is sent to step 400. The internal inspection step 400 shown in the present embodiment includes a light leakage inspection step 401 and a foreign matter inspection step 402, where the internal inspection is performed without disassembling the cartridge 1. . The order of the steps 401 and 402 is arbitrary.

In the light leakage inspection step 401, the light-shielding function of the telempe a4 provided in the slit opening a3 is inspected. Fig. 9 shows a conceptual diagram of the light leakage inspection in the light leakage inspection step 401. In the light leakage inspection step 401, housings 61 and 61 are provided so as to sandwich the patrone 1 from both sides, and both sides of the transferred pat opening 1 are connected to each hub b 1 and b of the spool 1B. 2 is completely shaded and covered. Light sources 62 and 62 are provided in each of the housings 61 and 61, and the light sources 62 and 62 are turned on so that light of a predetermined illuminance is emitted from the direction of the spool axis of the cartridge 1. I have. A light amount detecting means 63 composed of a photosensitive element such as CCD is disposed near the slit a3 of the cartridge 1, and detects the amount of light leaking from the slit a3.

In the inspection of light leakage by this, first, while the spool 1B is pressed against the short hub b2 side, light is irradiated from the long hub b1 side or both hubs b1, b2 side, and the opening a2 of the cap a1 → The amount of light that reaches the flange b 3 of the spool 1 B—the slit light a 3 is measured by the light amount detection means 63 and quantified. Next, light is emitted from the short hub b2 or both hubs b1 and b2 while the spool 1B is pressed against the long hub b1 in the same manner, and the amount of light leaking through the same path is detected by the light amount detecting means 6. Measure in 3 and digitize this. The detected value is sent to the light leakage determining means 64, and the degree of light leakage is determined by comparing the detected value with a predetermined reference value. As a result, if light leakage is detected exceeding the reference value, the product is to be discharged out of the process as an NG product.

In the light leakage inspection step 401, the inspection environment is a dark room (dark box), and the tail end film F is properly held from the slit a3 so as not to be in the way when measuring the light amount. It is preferable that the posture is kept constant by using.

The patrone 1 that has passed the light leakage inspection step 401 is sent to the foreign matter inspection step 402 by the rotation of the inspection lenslet 60. In this foreign substance inspection step 402, the presence or absence of foreign substances such as sand particles that have entered the patrone 1 is inspected.

FIG. 10 shows a conceptual diagram of the foreign substance inspection in the foreign substance inspection step 402. In the foreign matter inspection process 402, holders 65, 65 holding the cartridge 1A and the spool 1B from both sides of the cartridge 1 so that they do not move, and the cartridge 1 Appropriate vibrating means 66 such as a vibrator for applying vibration of a predetermined frequency to the body of the patrone 1 while being held at 5 is provided.

At the time of foreign substance inspection, noise detection means 67 composed of an acoustic detection probe (for example, a microphone) for detecting noise is brought into contact with the surface of the door opening 1, and vibration is applied by the vibration means 66. Detected noise inside the patrone 1. At this time, it is preferable that the vibration frequency given by the vibration means 66 is not constant but variable. If foreign matter such as sand particles has entered the patrone 1 here, the noise detected by the noise detecting means 67 is larger than a predetermined normal value (reference value). Is compared with a reference value by means of foreign matter presence / absence determination means 68. If the detected noise exceeds the reference value, it is regarded as a product to be discharged out of the process as an NG product with foreign matter. When the foreign matter inspection process 402 is completed, the inspection turret 60 is rotated counterclockwise by a predetermined angle, and the conformable patrone 1 that has passed the inspection is transferred to the next process. In addition, the products to be discharged in the above steps 401 and 402 are discharged from the inspection tray 60 at the position where the inspection turret 60 is further rotated. Each time a nonconforming product is determined in each of the steps 401 and 402, it may be discharged from the inspection turret 60 each time.

(5) Recovery process

The patrone 1 that has passed the internal inspection step 400 is sent to the collection step 500 from the inspection turret 60 at a predetermined position. Here, in the above-mentioned CAS pattern inspection step 305, they are classified and collected according to the type of the pat code 1 read from the CAS code or the product identification barcode.

In the collection step 500, trays 70a and 70b capable of storing a plurality of patrones 1 at a time are placed on an XY stage (not shown) that can move in the XY direction. Due to the movement in the XY direction, either tray 70a, 70b is located at the cartridge discharge position of the detector pallet 60 and can receive the cartridge 1.

At the bottom of the trays 70a and 70b, as shown in Fig. 11, a spool is inserted into the short hub b2 of the spool 1B of the cartridge 1 to hold the spool 1B so that it cannot rotate. A shaft fixing projection 71 protrudes from each of the pat ports 1 to be stored, and each of the pat ports 1 of the conforming product transferred from the inspection turret 60 is provided with a spool shaft fixing boss. 7 Fit into 1 and store and hold.

The patrone 1 transferred from the inspection turret 60 is divided into trays 70a and 70b for each type. The types of patrones that can be divided here are: And brands. In addition, a single tray may store a plurality of types of patrones 1 at a time by dividing the tray into types. In addition, each cartridge 1 is fixed in trays 70a and 70b so that the phase of spool 1B and the direction of slit slot a3 are all aligned.

The trays 70a and 70b can also be used as return boxes, and transport from the inspection process in a state where a plurality of patrones 1 are stored.

After the above inspections have been completed and all the inspections have passed the inspection, it is possible to determine that the patroller 1 is a patrone that can be used as a reused product by loading unexposed film. The film is transferred to a step of loading an unexposed film.

Hereinafter, an embodiment for achieving the second object of the present invention will be described in detail. First, a description will be given of the configuration of a photographic port (hereinafter simply referred to as a patrone) common to all aspects of the present invention described below.

Fig. 13 (a) is a perspective view showing the external configuration of the photo patrol door, Fig. 13 (b) is a cross-sectional view thereof, and Fig. 14 (a) is a spool housed in the cartridge. FIG. 14 (b) is a central sectional view of the spool. Here, we will describe the 135 film cartridge that holds the most typical 35 mm photographic film.

The patrone 1 is configured such that a spool 1B is built in a patrone body 1A formed into a cylindrical shape using a steel plate, and caps a1 and a1 are caulked and fixed to both sides thereof. An opening a2 is formed at the center of each cap a1, and each hub b1, b1 protruding at both ends of the spool 1B is supported by projecting outside from the opening a2. And it is rotatable inside the cartridge body 1A. The patrone main body 1A overlaps the inner surfaces of both ends of a cylindrically rolled steel plate with a gap therebetween, and folds the overlapped portion in the same direction and The main body 1A extends in the circumferential direction, and the gap formed in the overlapping portion becomes a slit a3 for inserting and removing a photographic film (not shown). The slit a3 has a light shielding property. There is a telep for a4.

The spool 1B is provided with flanges b3, b3 at both ends of a take-up shaft b2 for winding a photographic film, and concentrically provided with hubs b1, b1, respectively at the outside thereof. A slit-shaped spool hole b4 into which the leading end of the photographic film is inserted is formed in the take-up shaft b2, and a locking claw b5 and a locking claw b5 are locked in the spool hole b4. A holding rib b6 for preventing the detached photographic film from being provided is provided in opposition. In the embodiment shown in FIGS. 14 (a) and 14 (b), two locking claws b5 are provided at predetermined intervals in the sprue hole b4, and the holding rib b6 is located between the two. Although only one is provided, the number and shape of the locking claw b5 and the holding rib b6 are not particularly limited.

FIG. 15 is a schematic perspective view showing an example of a manufacturing apparatus suitable for carrying out the photographic film manufacturing method according to the first aspect of the present invention. In the manufacturing apparatus 2, reference numeral 29 denotes a patrone holder for holding the patrone 1, and the patrone 1 is held in the patrone holder 29 so that the slit opening a3 faces the film shot 22 described later. It is set.

The film chute 22 for supplying the photographic film to the patrone 1 is linearly arranged so that one end faces the slit a3 of the patone 1 held by the patrone holder 29. The film chute 22 is slidable along a direction in which the film chute 22 is disposed via a slide member 24 slidable along the guide rail 23. Therefore, the film chute 22 is slid by a driving means (not shown), so that the tip of the film chute 22 is set in the gate opening holder 29. 07144

28 Rhone 1 can be separated from and separated from Slitstro a 3.

In addition, 22 a and 22 a are film feed rollers for contacting the photographic film in the film chute 22 and transferring the photographic film toward the slit a 3 of the patrone 1. They are disposed vertically opposite to each other and are driven by driving means (not shown).

With the patrone 1 set in the patrone holder 29, the photographic film is locked to the spool of the patrone 1 between the slit opening a3 of the patrone 1 and the tip of the film chute 22. A guide member 3 serving as a guide for the operation is provided.

As shown in FIG. 16, the guide member 3 is formed by connecting a flat rear guide portion 3b and a flat rear guide portion 3b at a predetermined angle to the flat front guide portion 3a. It is shaped like a letter. It is preferable that the tip guide portion 3a and the rear end guide portion 3b are connected by a curved portion 3c having a predetermined radius, and the tip guide portion 3a, the curved portion 3c and the rear end guide are connected. The portion 3b is formed to have substantially the same width as the width of the slit opening a3. These can be easily formed integrally by bending and using a thin metal plate.

In addition, it is preferable that the inner angle formed by the planes of the front end guide portion 3a and the rear end guide portion 3b is 110 ° ± 20 °. When the guide member 3 is out of the above range, when the guide member 3 is inserted from the slit opening a3 into the patrol opening 1, the leading end guide portion 3a is moved to the position shown in FIG. 14 (a), FIG. 14 (b). It is difficult to guide the photographic film to the spool hole b4 without going to the spool hole b4 of the spool 1B shown in the figure. More preferably, it is 110 ° ± 5 °, most preferably 110 °.

The distal end of the distal end guide portion 3a is cut off on both sides, and the spool 1B It is formed in a narrow shape so as to substantially match the width of the hole b4.

At the side of the patrone holder 29, a block 25 for supporting the guide member 3 is slidably provided by driving means (not shown) along a film feeding direction by the film chute 22. A rotation shaft 26 projects from the block 25 to a position between the slit opening a3 of the cartridge 1 and the tip of the film chute 22 so as to be rotatable by driving means (not shown).

The block 25 has an elongated hole 25a cut out in the vertical direction, and the rotating shaft 26 projects from the elongated hole 25a so that the elongated hole 25a is formed. It is possible to move up and down along a. The amount of protrusion of the rotating shaft 26 from the block 25 is slid so that the block 25 is juxtaposed to the side of the patrone holder 29 (the leftmost position in FIG. 15), and However, even when the rotating shaft 26 is lowered to the lowermost end of the slot 25a, the tip of the rotating shaft 26 is attached to either the cartridge holder 29 or the pocket 1 held by it. It is assumed that they do not touch.

A mounting arm 26a protruding from the outer peripheral surface of the rotating shaft 26 extends along the axial direction thereof. The guide member 3 has a front end guide portion 3a whose front end faces the slit opening a3 of the patrone 1 set in the patrone holder 29, and whose rear end guide portion 3b faces the slit opening a3. 1 The outer surface on the rear end side of the rear end guide portion 3b so that it is inclined to the A side (lower side in the figure), that is, the inside bent in a substantially rectangular shape is arranged on the lower side in the figure. Is attached to the mounting arm 26a, and is rotated substantially along the curved portion 3c of the guide member 3 by the rotation of the rotation shaft 26 (first 17 (a)). See figure).

The pivot shaft 26 is arranged so that the distal end guide portion 3a of the guide member 3 is opposed to the patrone body 1A of the slit a3 of the patrone 1 set in the patrone holder 122. (The state shown in Fig. 17 (a)) and the position where the rear end guide portion 3b of the guide member 3 is parallel to the extension direction of the slit opening a3 (first position). 7 (c) state clockwise and counterclockwise.

Next, a method of manufacturing a photographic film using the manufacturing apparatus will be described. First, as shown in Fig. 13 (a) and Fig. 13 (b), a spool 1B is built in, and both sides are covered with caps a1 and a1, respectively. Set manually or automatically in 9 to position patrone 1. Here, the patrone 1 has its slit opening a 3 located at the upper part of the drawing and a film chute.

The spool 1B is arranged and held so as to face the tip of the spool 22. Further, as shown in FIG. 17 (a), the inlet side of the spool hole b4 faces the root direction of the slit port a3 as shown in FIG. 17 (a). At the right position and locked using appropriate position locking means.

When the patrone 1 is set in the patrone holder 22 and the position of the spool 1 B is locked, the rotating shaft 26 descends the long hole 25 a from the state shown in FIG. 17 (a). The guide member 3 attached to the tip is disposed near the slittro a3 of the patrone 1. At this time, the guide member 3 has its leading end guide portion 3a parallel to the extending direction of the slit roller a3 with respect to the cartridge body 1A (the direction in which the film is fed by the film chute 22), and the trailing end guide portion 3b has the slit groove portion 3b. It is held so that it is located on the part 1A side (lower side in the figure) of the pat mouth body a3.

When the leading end guide portion 3a of the guide member 3 reaches the height of the slit slot a3 of the patrone 1, the rotating shaft 26 stops descending. Next, the block 25 advances in the same direction as the film feeding direction, and the leading end guide portion of the guide member 3 attached to the rotating shaft 26.

3 Insert a through the slit a3 of the patrone 1. As a result, the guide member 3 has its tip guide portion 3a deformed by slit block a3 due to the advance of the block 25. 03 07144

It is inserted in a straight line parallel to the extension direction of the slit opening a3 without damaging the pump (see Fig. 17 (b)).

When the insertion of the guide member 3 is started, the rotation shaft 26 repeatedly rotates clockwise and counterclockwise alternately within a small angle range halfway through the insertion, and simultaneously with the forward movement of the block 25, the guide member 3 is swung so that the guide member 3 can be smoothly inserted.

When almost the entirety of the distal end guide portion 3a of the guide member 3 is inserted into the slit opening a3, and the vicinity of the curved portion 3c that reaches the slit opening a3, the block 25 becomes the rotating shaft 26. By gradually rotating the guide member 3, the guide member 3 is rotated counterclockwise in the drawing toward the inclined side so that the rear end guide portion 3 b of the guide member 3 is parallel to the extending direction of the slit opening a 3. While the guide member 3 is further advanced until the rear end guide portion 3b is inserted into the slit opening a3. As a result, the distal end of the distal end guide portion 3a of the guide member 3 moves toward the spool 1B in the opening 1 and comes close to the vicinity of the inlet of the spool hole b4. Almost at the same time, the film chute 22 and the film feed roller 22 a also move forward along the guide rail 23 toward the patrol opening 1, and the leading end of the film shoot 22 extends into the slit of the cartridge 1. Stop at a position close to mouth a3 (see Fig. 17 (c)).

Next, the unexposed photographic film F is fed out through the film chute 22 by the film feed roller 22a. The photographic film F sent from the leading end of the film chute 22 contacts the guide member 3 inserted into the slit a 3 of the pawl opening 1 while contacting along the inclined side (lower side in the figure) of the guide member 3. Inserted into slit a3. That is, the photographic film F is inserted into the slit a3 along the lower surface of the rear end guide portion 3b of the guide member 3 which is partially protruded from the slit a3 of the patrol opening 1, and then the curved portion 3 c Four

32, it is turned in the direction of the spool 1B along the curved surface, and then guided along the lower surface of the tip guide portion 3a to the spool hole b4. The photographic film F whose leading end is guided to the spool hole b4 is provided with each of the locking claws b5 provided in the spool hole b4 shown in FIGS. 14 (a) and 14 (b). The locking holes formed in the leading end of the photographic film F are locked with b5 and b5 (see FIG. 17 (d)). When the photographic film F is locked on the spool 1B, the film chute 22 and the film feed roller 22a move back along the guide rail 23. At this time, the photographic film F in the film shoot 22 does not retract because it is locked on the spool 1B. Next, the block 25 starts to retreat, and the rear end guide portion 3 b of the guide member 3 attached to the rotating shaft 26 is pulled out from the slit a 3 of the cartridge 1. At this time, the rear end guide portion 3b is pulled out in a straight line parallel to the extending direction of the slit slot a3 by the retreat of the block 25. At the same time, the rotating shaft 26 repeats rotating within a minute angle range as in the case of insertion, so that the guide member 3 is pulled out together with the block member 25 so that the guide member 3 can be pulled out smoothly. Rock it.

Thereafter, the block 25 is gradually rotated at the same time as the retreating operation and the rotating shaft 26 is rotated so that the distal end guide portion 3 a of the guide member 3 is parallel to the extending direction of the slit b a 3. 3 is turned clockwise in the figure toward the inclined side, and then the distal end guide portion 3a is pulled straight out, and the guide member 3 is taken out from the slit opening a3. In the removal operation of the guide member 3, the front end guide portion 3a and the rear end guide portion 3b of the guide member 3 are respectively drawn out in a straight line along the plane, so that the insertion operation is not performed. Similarly, there is almost no interference with the slit opening a3 of the patrone 1, and even if it does, the corner of the tip of the guide member 3 does not contact, so that there is little effect on the slit opening a3 and telemump. . When the guide member 3 is removed, the rotation of the guide member 3 causes the rear end of the rear end guide portion 3b to come into contact with the upper surface of the photographic film F protruding from the slittro a3 of the patrone 1, and further rotated. Accordingly, the film path line of the photographic film F between the slit a3 and the film chute 22 is bent downward in a V-shape (see FIG. 17 (e)). At this time, since the leading end of the photographic film F is locked and fixed to the spool 1B, the photographic film F located in the film chute 22 is directed toward the cartridge 1 with the bending of the film path line. Will move. Therefore, by detecting the movement of the photographic film F at this time by appropriate means, it is possible to automatically detect that the leading end of the photographic film F is securely locked to the spool 1B. is there.

The rear end portion of the guide member 3 or the mounting arm 26a, which comes into contact with the upper surface of the photographic film F, is formed into a curved surface as shown in the figure, so that the damage to the photographic film F at the time of contact is reduced. It is desirable to do.

After the guide member 3 is taken out of the patrone 1, the rotating shaft 26 moves up along the long hole 25a to retract the guide member 3 upward from the film path line. As a result, the pass line of the photographic film F becomes straight (see Fig. 17 (f) and Fig. 17 (g)). Next, the photographic film F locked on the spool 1B is wound up by rotating the spool 1B of the patrone 1 and the film feed roller 22a. At this time, since the guide member 3 is taken out from the opening 1 and retracted from the film path line, the photographic film F does not come into contact with the guide member 3 at the time of winding, and the photographic film F is damaged. There is no need to worry about the occurrence. The photographic film is completed by winding the photographic film F.

Next, a method for producing a photographic film according to the second aspect of the present invention will be described. 07144

34 A manufacturing apparatus suitable for use in carrying out the manufacturing method according to the second aspect has a different configuration of the guide member in the manufacturing apparatus 2 described in the first aspect.

The configuration of this guide member is shown in Figs. 18 (a) and 18 (b). In the following description, the same reference numerals as those in FIGS. 13 (a) to 17 (g) denote the same components.

The guide member 4 has a hollow shape having an upper guide plate 41 located on the upper side in the figure, a lower guide plate 42 located on the lower side in the figure, and side guide portions 43 and 44 shielding both sides thereof. A front end guide portion 4a extending linearly formed by an upper guide plate 41, a lower guide plate 42, and side guide portions 43, 44 at a front end thereof, and a rear end. Similarly, the rear guide 4b, which is formed by the upper guide plate 41, the lower guide plate 42, and the side guides 43, 44, which are linearly formed, is inclined at a predetermined angle. It is connected in a substantially rectangular shape having a curved portion 4c having a predetermined radius between the leading end guide portion 4a and the trailing end guide portion 4b. Is formed. Also, the ends of the upper guide plate 41 and the lower guide plate 42 in the front end guide portion 4a are cut off on both sides, and substantially match the width of the spool hole b4 of the spool 1B. It is formed in a narrow shape as shown in FIG.

The inner angle α formed by the planes of the front end guide portion 4a and the rear end guide portion 4b is 110 ° ± 20 °, more preferably 110 °, for the same reason as the guide member 3. 5 °, most preferably 110 °.

The guide member 4 is attached to the attachment arm 26a of the rotating shaft 26 projecting from the block 25 in the same manner as the guide member 3 in the first aspect described above.

In a method of manufacturing a photographic film using a manufacturing apparatus having the guide member 4, Since the operation of inserting the guide member 4 into the slit opening a3 of the patrone 1 is the same as the operation of the guide member 3 in the first aspect described above, detailed description is omitted. The operation of inserting the photographic film F into the guide member 4 inserted into the patrone 1 is performed through the film passage p in the guide member 4. At this time, since the upper and lower surfaces of the photographic film F are supported by the upper guide plate 41 and the lower guide plate 42, respectively, the photographic film F is inserted without bending in the insertion process, and moreover, both sides of the film path P Since the photographic film F is shielded by the side guides 43 and 44, both ends of the photographic film F are also supported when the photographic film F is inserted, so that the photographic film F can be smoothly fed.

Thereafter, the operation of locking the photographic film F to the spool 1B and the subsequent operation of removing the guide member 4 from the patrone 1 are the same as those of the guide member 3 in the first aspect described above.

In this guide member 4, after the photographic film F is locked on the spool 1B, when it is taken out of the patrone 1, the state is the same as that shown in Fig. 17 (e). The film path line between 2 and 2 is bent downward in a V-shape, and then the spool 1 B of the patrone 1 and the film feed roller 2 2 a are rotated while the film path line is bent, Take up the photographic film F locked on the spool 1B to complete the photographic film.

Next, a method for producing a photographic film according to a third aspect of the present invention will be described. A manufacturing apparatus suitable for use in carrying out the manufacturing method according to the third aspect is different from the manufacturing apparatus described in the first aspect in the configuration of the guide member and the periphery thereof.

FIG. 19 shows the structure of the guide member and its surroundings. In the following explanation 13 (a) to 17 (g) indicate the same components.

The guide member 5 has a structure in which two guide members 3 in the first aspect described above are prepared and stacked vertically at a predetermined interval, and an upper guide plate 51 located on the upper side of the drawing is provided. A film path P is formed by a gap with the lower guide plate 52 located on the lower side in the figure.

The upper guide plate 51 and the lower guide plate 52 are, like the guide member 3 in the first aspect described above, respectively flat-shaped guide members 51a and 52a, respectively. The guides 51b and 52b are connected at a predetermined angle in an inclined manner, and between the front guides 51a and 52a and the rear guides 51b and 52b. It has a substantially rectangular shape provided with curved portions 51c and 52c having a predetermined radius. The lower surface shown at the rear end of the lower guide plate 52 is attached via a mounting arm 27a to a lower rotation shaft 27 provided in an elongated hole 25a of the block 25, and The illustrated upper surface of the rear end of the guide plate 51 is attached via an attachment arm 28a to an upper rotation shaft 28 similarly provided in the elongated hole 25a of the block 25.

The upper rotation shaft 28 has a downward U-shaped concave portion 28 b fitted to the outer peripheral surface of the cylindrical lower rotation shaft 27, and the upper rotation shaft 28 The upper guide plate 51 and the lower guide plate 52 are installed side by side so as to overlap each other with an interval corresponding to the film path p therebetween while being fitted to the outer peripheral surface of the side rotation shaft 27. The rotating shaft 28 can rotate integrally and concentrically with the lower rotating shaft 27. As a result, the guide member 5 becomes rotatable as a whole, and when the upper rotation shaft 28 and the lower rotation shaft 27 are separated from each other in the elongated hole 25a and the fitting is released, The upper guide plate 51 and the lower guide plate 52 are vertically separated from each other, and the film path P therebetween is largely opened.

Next, a method for manufacturing a photographic film using a manufacturing apparatus having the guide member 5 will be described. Will be described. The guide member 5 performs insertion and removal operations with respect to the slit a3 of the patrone 1 in a state where the upper guide plate 51 and the lower guide plate 52 are juxtaposed so as to overlap with each other. Since the inserting operation and the removing operation are the same as the case of the guide member 3 in the first aspect described above, the description of the overlapping portions is omitted, and the different portions are shown in FIGS. 14 to 18. This will be described with reference to FIG.

The guide member 5 is in a state in which the upper rotation shaft 28 is fitted to the lower rotation shaft 27, that is, the upper guide plate 51 and the lower guide plate 52 have a film path p therebetween. In a state where the cartridges are overlapped, the cartridge holder is operated by the same operation as in the case of the first viewpoint described above so that the leading ends of the leading end guide portions 51a and 52a approach the spool hole b4. It is inserted into slitro a3 of patrone 1 which is set to one 29 (see FIG. 20 (a)).

Next, the photographic film F is sent out through the advancing film chute 22. Here, the photographic film F sent out from the tip of the film chute 2 2 passes through the film passage P formed in the guide member 5 inserted into the slit opening a 3 of the cartridge 1, and the slit film a 3 Is inserted into. At this time, since the upper and lower surfaces of the photographic film F are supported by the upper guide plate 51 and the lower guide plate 52, respectively, the photographic film F can smoothly reach the spool hole b4 of the spool 1B without bending during the insertion process. It is guided and locked (see Fig. 20 (b)).

Next, the block 9 starts retreating, and the guide member 5 is pulled out and rotated in the same manner as in the case of the first aspect described above, and the guide member 5 is taken out from the gate 1 (20 (c)). See figure). At this time, the photographic film F is bent downward in a V-shape along the film path line between the slit opening a3 and the film chute 22 as in the above case. However, when the guide member 5 is taken out of the patrone 1, the upper rotation shaft 28 is separated from the lower rotation shaft 27 and rises along the long hole 25a of the block 25. As a result, the upper guide plate 51 of the guide member 5 is separated from the lower guide plate 52, and the film passage p therebetween is largely opened upward, and the pass line of the photographic film F becomes straight (20th line). (See Fig. (d) and Fig. 20 (e).)

Next, the photographic film F locked on the spool 1B is wound up by rotating the spool 1B of the patrone 1 and the film feed roller 22a to complete the photographic film. At this time, the guide member 5 is taken out of the patrone 1 and the upper guide plate 51 is retracted from the film path line to open the film path p greatly. There is no risk of scratching the photo film F.

Another embodiment of the guide member 5 in the third aspect is shown in FIG. The drawing shows only a lower guide plate 52 different from the above guide member 5, and both side ends of the lower guide plate 52 have side guide portions 5 standing up toward the film passage p side. 3, 5 and 4 are formed. The side guide portions 53 and 54 are formed so as to cover both sides of the film passage p when the upper guide plate 51 shown in FIG. 19 is overlapped with the film passage p. . This prevents the upper guide plate 51 and the lower guide plate 52 from bending when the photographic film is inserted, as well as the side guide portion, similarly to the guide member 4 in the second aspect described above. 5 3 and 5 4 support the both ends when the photographic film is inserted to form a lateral guide, enabling smoother feeding operation. According to this guide member 5, the upper guide plate 5 1 Since the lower guide plate 52 can be separated from the guide member 4, unlike the guide member 4 in the second aspect, the film can be wound up with the film path line after the guide member 4 is taken out in a straight line, Second point of view The risk of damaging the photographic film is smaller than that of the photographic film.

The side guide portions 53 and 54 are not limited to the illustrated form, and may be provided on the upper guide plate 51 side of the guide member 5. For example, one side guide portion 53 may be provided on the upper guide plate. The guide plate 51 may be provided with the other side guide portion 54 separately on the lower guide plate 52.

Although not shown, the side guide portion may be formed so as to stand on the guide member 3 in the first aspect described above so as to face the side (the lower side in the figure) where the photographic film is in contact. Thus, even in the first aspect, when the photographic film is inserted, the both sides are supported and a lateral guide is formed, so that a smoother feeding operation can be performed.

In each of the aspects of the present invention described above, the orientation of the cartridge 1 is set so that the slit a3 is positioned upward, but the cartridge is set so that the slit a3 is positioned downward. The holder 21 may be set. In this case, the guide members 3, 4, and 5 are also arranged upside down as shown in the figure, and the rotation of the guides 3, 4 and 5 is also reversed.

Further, the aspects of the present invention described above are not limited to the case where a novel photographic film is manufactured. In other words, if the photo cartridge has a built-in spool and both sides are covered with caps, the same applies to used cartridges as well as lost cartridges and cartridges collected due to expiration. It is possible to reuse the patrone. In this case, the film retained by the spool and remaining in the opening of the patrol opening is removed by tearing off the spool or the like, and then the above method may be applied.

Hereinafter, an embodiment for achieving the third object of the present invention will be described with reference to the drawings. explain.

First, an example of the configuration of the patrone will be described.

FIG. 22 is a perspective view showing an external configuration of a 135 type photographic patrone, FIG. 23 (a) is a perspective view of a spool housed in the pat opening, and FIG. The figure is a central sectional view of the spool.

The patrone 201 accommodates a spool 202 in a patrone body 210 formed in a cylindrical shape using a thin metal plate, and caulks and fixes caps 211 and 211 on both sides thereof. It is configured. An opening 211a is formed in the center of each cap 211, and the hubs 223a and 223b at both ends of the spool 202 are supported to form the inside of the notrone body 210. , The spool 202 is rotatably accommodated.

In the patrone main body 210, both ends of a metal thin plate rolled into a cylindrical shape extend in the circumferential direction, and a gap formed between the two thin plates serves as a slit roll 212 when the film F is taken in and out. A mouthpiece 21 3 is provided for the mouth 2 12 to have a light-shielding property.

The spool 202 has flanges 222, 222 at both ends of a winding shaft 222 for winding the film, and a long hub 2223a and a short hub 2223b outside thereof. It is provided concentrically. A slit hole 2 24 for inserting the tail end of the film is formed in the winding shaft 2 21, and a locking claw 2 25 and a holding rib 2 2 6 are formed in the slit hole 2 24. Is provided.

In the embodiment shown in FIGS. 23 (a) and 23 (b), two locking claws 2 25 are provided at predetermined intervals in the slit hole 2 24, and one holding rib 2 26 is provided. Only provided. The locking claws 2 2 5 and 2 2 5 and the holding rib 2 2 6 are arranged opposite to each other in the slit hole 2 24, and the holding rib 2 2 6 is attached to each locking claw 2 2 5 The 2 2 5 0307144

41. Further, as shown in FIG. 23 (b), the protrusion heights of the locking claws 225, 225 and the holding rib 226 are set so as to overlap each other when viewed from the side, and each of the film claws 225, 225 has a film height. The entry side surfaces 225a, 226a are formed in a tapered shape so that the tail end of the film inserted into the slit hole 224 is smoothly guided between the locking claws 225, 225 and the holding rib 226. You.

The structure for locking the spool 202 and the tail end of the film differs from the above-described embodiment depending on the type of the patrol port, such as a difference in manufacturer or a type. That is, in the embodiment shown in FIG. 24 (a), only one locking claw 225 for locking the film is provided in the slit hole 224, and the tail end of the film locked by the locking claw 225 is fixed to the slit. Two pressing ribs 226, 226 for pressing are provided to face the locking claw 225 so as to sandwich the locking claw 225 therebetween. In the embodiment shown in FIG. 24 (b), the number of the locking claws 225 is two, as in FIGS. 23 (a) and 23 (b). Two pressing ribs 226 are provided between the locking claws 225 and 225 so as to face the 225.

In addition, even if the numbers of the locking claws 225 and the holding ribs 226 are the same, the intervals at which the locking claws 225 and the holding ribs 226 are arranged may be different.

On the other hand, the film is formed in a narrow shape in which the film tail end Fa side inserted into the spool hole 224 of the spool 202 is cut off on both sides as shown in FIG. The case where the film tail end Fa is locked to the spool shown in FIGS. 23 (a) and 23 (b) will be described. Two locking holes Fb, Fb for locking with the respective locking claws 225, 225 are provided. Each of the locking holes Fb, Fb corresponds to each of the locking claws 225, 2 of the spool 202. By engaging with 25, the film tail end Fa is locked to the spool 202. The holding ribs 2 26 in the slit holes 2 24 are positioned between the respective locking claws 2 25, 2 25 with the film tail end Fa locked to the spool 202 in this manner. The film tail end Fa is pressed toward the locking claws 2 25 and 2 25, and the film tail end Fa is accidentally disengaged from the locking claws 2 25 and 2 25. Has been prevented.

The used patrone 201 is cut off in the vicinity of the slit opening 212 while the film tail end Fa is locked on the spool 202, and a part of the film tail end Fa is cut into the slit slot 210. You are out of 1 2 In the present invention, the film (hereinafter, referred to as an old film) locked on the spool 202 is removed from the patrone 201 in this state without disassembling the patrone 201 at all. By locking a new unexposed film (hereinafter, referred to as a new film) on the spool 202, it is possible to reuse the pato mouth 201.

The old film used in this specification is not limited to film that has been used (photographed), but may also be used for the collection of lost products produced during the manufacturing process of patrones with film or expired products that have expired at stores. Includes unused film locked in the patrone. Therefore, in the following description, the term "used pato mouth" refers to not only a used film but also a production loss product or an expired product in which an unused film is locked.

Next, an embodiment of a method for reusing a photographic door opening according to the present invention will be described with reference to FIG.

First, in the type discriminating step 150, the used patrone 201 with only a part of the tail end of the old film coming out of the slit opening 212 as shown in FIG. The type of 201 is determined. The type of the patrone 201 determined here is mainly the strength of the patrol mouth 201. This is because the structure for locking the spool 202 and the film differs depending on the manufacturer, so that the removal and locking of the old film suitable for each machine can be performed. In addition, the type of the patrone 201 may be determined.

The discrimination of the type of the patrol mouth 201 can be made by using the DX bar code (manufacturer, variety, etc.) recorded on the surface of the patron 201, the manufacturer's unique code, design, etc. This is done by reading. In addition, if the number of reuses (reuse) times is recorded in the No. ローネネネネネネネ 0 0 1 1 1 リューリューリューリューことパリューことパ. You may do so. As a specific type discriminating means for performing these discriminations, a reading device such as a code reader for reading a code such as a bar code from the patrol port 201 and a patrol port 2 can be used. A patrone such as an image recognition device or the like for recognizing the design by optically observing the appearance of 01 using a television camera or the like and comparing the type with a previously stored image. Appropriate means according to the recording mode for the 201 surface can be used.

When the type of the opening 201 is determined by these means, the locking structure between the spool 202 and the film according to the type is determined. Therefore, when removing the tail end of the old film from the patrol opening 201 and locking the new film in the subsequent process, it is necessary to select the most suitable jig according to the type of the patrone 201. It becomes possible. The patrone 201 whose type has been determined is inspected in the next inspection step 250. In the present invention, in order to remove the old film and lock the new film, a part of the tail end of the old film locked on the spool 202 is formed by the slit opening 21 of the opening 21 1. Must be out of 2. So here, the tail end of the old film It is preferable to perform an inspection as to whether or not a part of the cartridge comes out of the slit opening 212 of the patrone 201.

Automated inspection is possible by using a photoelectric sensor as an inspection means for inspecting whether a part of the tail end of the old film is protruding from the slit opening 2 1 2 of the opening 21 2 It is.

Here, the film is cut into the patrone 201 so that a part of the tail end of the old film coming out of the patrone 201 slit opening 212 does not enter the patrone 201. After rotating the spool 202 in the direction of exiting the port 212, it is preferable to take appropriate means such as a spool phase locking means for locking the phase of the spool 202.

In addition, in addition to the above, the inspection at this time includes inspection of dirt (dust adhesion, cracks) on the surface of the pachinko mouth 201 by image recognition processing, and the slit mouth 211 and cap 211, It is also preferable to carry out a deformation inspection of the plastic mouth body 210, and also to perform a light-shielding condition inspection, a plastic mouth height inspection, a spool / cap clearance inspection, a CAS detection inspection, etc. It is also preferred.

This inspection may be performed simultaneously with the type determination in the type determination step 150.

The patrol mouth 201 passed in the inspection then separates the tail end of the old film locked on the spool 202. Prior to this separation, a plurality of types of patrol cartridges 201 are separated. When processing 1, it is preferable to select a jig suitable for each locking structure between the spool 202 and the tail end of the film. That is, the types determined in the first type determination step 150, that is, the structures of the locking claws 2 25 and the holding ribs 2 26 are, for example, shown in FIGS. 23 (a) to 23 (b). Figure 24 (a) to Figure 24 (b) The optimal jig configuration for removing the tail end of the old film from the spool 202 will naturally differ depending on whether it hits. For this reason, in the next jig selection step 350, the tail end of the old film is separated from the spool 202 and the new film is separated according to the type of the patrone 20Γ determined in the type determination step 150. Select the jig for locking the to the spool 202.

The next film separation step 450 is a step of removing the old film from the patrone 201 using the above jig.

FIG. 27 shows an example of a separating means used for removing the old film from the patrone 201 in the film separating step 450. In the figure, reference numeral 351 denotes a patrone holder for holding the pat mouth 201. The pocket 201 is held in the cartridge holder 351, and is formed at the tail end F1a of the old film coming out of the slit 21-2. The two locking claws 3 52 a and 35 2 a of the tail end pulling member 35 2 are set to be locked in one foration F 1 c. A film chute 3553 for supplying a new film to the patrone 201 is arranged so that one end faces the slit 211 of the patrone 201 held in the patrone holder 351. At the same time, a guide rail 354 is provided in parallel with the film chute 353. A slide member 365 is slidably provided on the guide rail 355, and the slide member 355 is provided with an arm 355a disposed over the upper surface of the film chute 355. The tail end pulling member 352 is attached to the lower surface of the arm portion 35a.

The guide rail 354 is provided with another slide member 356 so as to be slidable. The slide member 356 has an arm 356a disposed over the upper surface of the film shoot 353, and is provided below the arm 356a. A separating and locking jig 357 extending toward the above-mentioned gate opening 201 is attached to the surface.

The separation and locking jig 357 is formed in a thin plate shape having substantially the same width as the film, and the tip thereof has a slit 21 2 of the patrone 201 held by the patrone holder 35 1. 2, and is disposed so as to be inserted between the tail end pulling member 352 and the film shroud 353.

An example of the separation and locking jig 357 is shown in FIG. The leading end 357 a of the separation locking jig 357 is formed in a narrow shape with both sides cut off. The separating and locking jig 357 has a distal end 357a having at least bending elasticity, and is formed using, for example, a 0.3 mm thick PET resin sheet.

The end of the tip 357 a is formed by a locking claw 2 25, 2 formed in a slit hole 2 24 of the spool 202 shown in FIGS. 23 (a) and 23 (b). It is divided into two according to the number of 25. In this embodiment, a triangular notch 3557b is formed at the tip 3557a, and a slit 3557c is formed linearly with a predetermined length at the deepest portion of the notch 3557b to form an end. Is divided into two.

When inserted into the slit hole 222 of the spool 202, the distal end 357a of the separating / locking jig 357, as described later, locks the slit hole 224 in the slit hole 224. It is necessary that the claws 2 25 and 2 25 do not rupture and that they do not push against the film tail end F 1 a locked on the spool 202. Therefore, the rigidity of the tip 357a of the separation locking jig 3557 is smaller than the rigidity of the spool resin and larger than the rigidity of the film.

In FIG. 27, reference numeral 358 denotes a feed roller for transferring a new film in the film chute 353 toward the slit 211 of the cartridge 201, and reference numeral 359 denotes a cartridge. Attach and discharge tail edge F 1 a of old film removed from 1 The suction cup for suction and discharge at the tail end is capable of moving up and down on the upper surface of the film chute and moving between the upper surface and a position off the upper surface. It is said.

Next, this operation will be described. First, hold the used pat mouth 201 in the pat mouth holder 351, and attach the front end F1a of the old film F1a that comes out of the slit slot 211 to the tail end. The tension member 35 52 is set by being locked to each of the locking claws 35 52 a, 35 52 a. Here, a certain amount of tension is applied to the tail end F 1 a by slightly moving the slide member 35 5 in a direction in which the tail end pulling member 35 2 is separated from the patrone 201. In this state, each of the locking claws 2 25, 2 25 in the spool 202 is moved from the lower surface side of the tail end F 1 a of the old film to the tail end F 1 a in the slit hole 222. Is locked.

Next, the slide member 356 is slid, and the separation / locking jig 357 is moved toward the slit 211 of the cartridge 201 (FIG. 29). By this movement, the tip 357 a of the separation and locking jig 3557 is moved from the slit opening 21 2 to the slit hole 2 24 of the spool 202 as shown in FIG. 30 (a). On the other hand, it is inserted between the tail end F 1 a of the old film and each of the locking claws 2 25, 2 25. At this time, the tip 357 a of the jig for separation and locking 3.57 a is pulled from the slit opening 2 1 2 of the nozzle 200 to the slit hole 2 2 4 of the spool 202 by pulling the tail end. While being guided by the tail end F1a of the old film, which is tensioned by the member 352, the bending elasticity allows it to be smoothly inserted along the film tail end F1a.

Immediately before the tip 357 a of the separation locking jig 357 reaches the tapered surface of each locking claw 2 25, 2 25, as shown in Fig. 31, the old film Set the tension applied to the tail end F1a of the film to 0, or set the tail end F1a of the old film to the patrone 201 side. By pushing back, the locking holes Fb and Fb of the tail end F1a are easily detached from the locking claws 2 25 and 25.

Thereafter, when the tip 357 a of the separation locking jig 3557 is further inserted, it is guided over the taper of each of the locking claws 2 25, 2 25 and guided by the locking claws 2 25. Ride on top of, 2 2 5 At this time, the tip 357 a of the jig for separation and locking 35 7 is provided with a holding rib 2 2 provided in the slit hole 2 24 so as to face each of the locking claws 2 25 and 2 25. 6 and the two ends divided by the slit 357c are bent in a substantially V-shape as shown in Fig. 30 (b) due to bending elasticity. It acts so as to release the holding force in the direction of the locking claws 2 25, 2 25 by the ribs 2 26. Therefore, the leading end 357 a of the separation locking jig 357 becomes a state in which the outer side bent in a substantially V shape floats, and as a result, the tail end F 1 a of the old film is The pawls 2 25 and 2 25 are lifted from the outside of the pawls 2 25 and 2 25 to above. As a result, the locking holes Fb and Fb of the tail end F1a of the old film are floated from the locking claws 2 25 and 2 25, and the engagement between them is released.

As described above, when the engagement between the tail end Fla and the locking claws 2 25, 2 25 is released, only the slide member 35 5 is slid and the tail end pulling member 35 2 is pulled out. It is moved in a direction to pull it away from the gate opening 201 (Fig. 32). As a result, the tail end F 1 a of the old film is removed from the opening 201. Next, the sucker for tail-end suction / discharge 359 descends to the tail end F1a of the removed old film, adsorbs it, and then ascends again to remove it from the tail-end tension member 352. At this time, the separation locking jig 3557 is inserted into the slit hole 24 of the spool 202, with the tip 3557a passing through the slit opening 21 of the gate opening 21. It remains sandwiched between the locking claws 2 25 and 2 25 and the holding rib 2 26.

In this way, when the tail end F1a of the old film is removed from the patrol opening 201 and the new film F2 is locked, in the next film winding step 650, the locked new film The film F2 is wound on a spool 202. Here, the operation can be performed as it is with the patrone 201 held in the patrone holder 1351.

As described above, according to the method for reusing a photographic patton according to the present invention, the tail end of the old film can be removed without disassembling the patrone at all, and the new film can be locked. , Can be wound up. Therefore, it is possible to greatly reduce the amount of waste when reusing the pato mouth.

Moreover, if the jig used for separating the tail end F 1 a of the old film is used as a guide to lock the new film F 2, the separation of the tail end F 1 a of the old film and the new film can be performed. Using the same separating and locking jig 3557 for locking the system F2, the jig for separating and locking 357 is inserted through the slit 2 1 2 With only one insertion, the old film tail edge Fla can be separated and the new film F2 can be locked as it is.When the new film F2 is locked, a new dedicated jig must be replaced. Also, it is not necessary to perform the film locking operation separately from the film separation operation, and the operation process can be simplified. Next, a reuse system for a photographic pout mouth according to the present invention will be described with reference to FIG. This reuse system is a systematization of a series of steps from the step 150 for discriminating the type of patrol mouth to the film winding step 650 in the method for reusing a photographic cartridge described above. A description of a portion overlapping with the description of the method for reusing the photo patrone will be omitted.

In this reuse system, when the type of the cartridge is determined in the type determining step 150, the locking structure between the spool and the film according to the type of the cartridge is automatically determined. The determination of the locking structure can be realized by preparing a data table in which the type discriminating means stores in advance the relationship between the type of pawl and the spool structure.

An example of this data table is shown in FIG. The table has a patrone code column 151, a patrone type column 152, a spool structure column 153, and a used jig column 154.

For example, the code information recorded in the DX bar code on the surface of the patrone is stored in the patrol port code field 151 in advance.

The patrone type column 152 stores the type of patrone for each of the above-described code information, for example, the type, the type, and the like of each item. Here, four types of pato mouths, A, B, C, and D, are stored.

The spool structure column 153 stores information on the structure of the spool for each of the above-mentioned pat-mouth types 口 152. This spool structure column 15 3 is further divided into locking claw number column 15 3 a, locking claw spacing column 15 3 b, holding rib number column 15 3 c, and holding rib spacing column 15 3 d. In each column, information on the number of locking claws, the number of pressing ribs, and the interval between them for each kind of patrol mouth is stored. The used jig column 154 stores the type of jig most suitable for each patrone type having the spool structure specified in the spool structure column 153. Here, three types of jigs, a, b, and c, are specified for patrone types A, B, C, and D. Note that the jig here is a separation-related jig that is common when the film is separated and when the film is locked. In the reuse system according to the present invention, when the type of the patrone is determined in the type determining step 150, a jig optimal for the patrone is automatically determined based on the data table.

An example of the processing flow in the type determination step 150 will be described with reference to FIG. 36. First, a DX bar code recorded on the surface of the patrone is read by a barcode reader (S1). ). Next, the read information is referred to the data table shown in FIG. 35 (S 2). As a result, if the read code is "1 2 3 4", it is known that this patrone type is "A", and the spool structure is as specified in the spool structure column 15 3. It turns out to be something. Thus, the used jig is determined to be the “a” jig from the used jig column 154 (S 3). Here, if the read information is not stored in the data table, the part is discharged as inapplicable to the present system (S4). Then, when the type of the patrol mouth is determined, the patrone is separated into, for example, a storage tray or the like using an appropriate separating means for each type (S5). As a result, in the subsequent process, the processing can be performed for each type of the separated cartridge, and the processing can be efficiently performed.

After this type determination step 150, a tail end inspection or the like is performed in an inspection step 250, and the patrone that has passed the inspection is subjected to a jig selection step 350 in accordance with the patrone type based on the data table. The jig determined according to is selected. The selection of the jig is performed by setting the separation and locking jig 357 in the separation and locking means shown in FIG. The separation and locking means may be prepared in multiple units for each type of jig, and for each separated type, only one type of pato mouth shall be provided. It may be arranged to automatically distribute to the separating and locking means having a suitable jig. When a large number of pats are processed, the latter is more advantageous in terms of processing efficiency.

When the jig is selected, as described above, the separation and locking means shown in FIG. The film is locked, and the new film is wound on a spool.

ADVANTAGE OF THE INVENTION According to the re-use system of the patrone for a photograph which concerns on this invention, the tail end of an old film can be removed, without disassembling a patrone at all, and a new film can be locked and wound up. . Therefore, when the patrone is reused, garbage can be significantly reduced.

Also, if the jig used to separate the tail end F1a of the old film is used as a guide to lock the new film F2, the separation of the tail end F1a of the old film and the new film Using the same separating and locking jig 357 for locking the F2, the separating and locking jig 3557 is once passed through the slit 21 Just by inserting the new film F2, the old film tail end F1a can be separated and the new film F2 can be locked. Also, it is not necessary to perform the film locking operation separately from the film separating operation, and the operation process can be simplified.
