[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for manufacturing a patrone body plate containing a photographic roll film. More specifically, the present invention relates to a method and an apparatus for supplying a thin metal plate that is cut so that its vertical and horizontal dimensions are the same as the developed vertical and horizontal dimensions of a Patrone body plate, and obtaining a body plate having a generally boat-shaped cross section with velvet ribbons at both ends.

[0002]

2. Description of the Related Art A cartridge containing a photographic roll film comprises a tubular body plate, a spool housed in the body plate, a photographic roll film, and caps for closing openings at both ends of the body plate. Composed. In addition, a velvet ribbon for light shielding called a teremp is attached to the inner surface of the film outlet of the body plate.

In order to manufacture a Patrone body plate, first, a thin metal plate that is cut so that the vertical and horizontal dimensions are the same as the developed vertical and horizontal dimensions of the Patrone body plate is processed into a substantially boat-shaped cross section, and then,
A velvet ribbon is attached to both left and right ends of a thin boat-shaped metal plate. In this case, while transporting a plurality of thin metal plates in a state where the front end and the rear end are substantially in contact with each other and continuously carrying them, two long velvet ribbons coated with an adhesive are continuously connected to the left and right ends of the thin metal plate, respectively. Stick it on. Then, the velvet ribbon between the adjacent thin metal plates is cut with a cutter. As a result, the Patrone body plate is manufactured.

As shown in FIG. 28, the Patrone body plate manufacturing apparatus disclosed in Japanese Patent Publication No. 53257/1993 has a sheet feeding station 1, a corner cutting station 2, a small diameter bending station 3, a goby bending station 4, 28. A double-sided bending station 5, thin plate transport rails 6 and 6 arranged below the respective stations 1 to 5 and connecting the stations 1 to 5, and between these rails 6 and 6, an arrow A shown in FIG. The feed lever 7 is configured to intermittently reciprocate in the direction.

FIG. 29 shows the thin plate feeding station 1.
A large number of metal thin plates 8 having the same vertical and horizontal dimensions as shown in (a) are the same as the developed vertical and horizontal dimensions of the cartridge shell. The thin metal plates 8 are conveyed one by one from the thin plate supply station 1 to the corner cutting station 2 by the intermittent movement of the feed lever 7 in FIG. Metal sheet 8 at corner cutting station 2
The four corners are cut into a predetermined shape as shown in FIG. Next, the metal sheet 8 is attached to the corner cutting station 2
Is conveyed to the small-diameter bending station 3, and the small-diameter bent portions R and R are press-formed at the two corners of one end of the thin metal plate 8 at the small-diameter bending station 3 as shown in FIG. The bent portion R is for bending the thin metal plate 8 into a cylindrical shape to facilitate the fitting when the cap of the cartridge is fitted.

Next, the metal thin plate 8 is conveyed to the goby bending station 4, where the goby bent portion 8a is press-formed at the other end of the metal thin plate 7 as shown in FIG. 29 (d).
After that, the thin metal plate 8 is conveyed to the both-end bending station 5, where the both ends of the thin metal plate 7 are bent and formed to have a predetermined curvature as shown in FIG.
The Patrone body plate is manufactured by the above procedure.

As described above, the velvet ribbons are attached to the left and right ends of the patrone body plate manufactured as described above.

The ribbon sticking device disclosed in Japanese Examined Patent Publication No. 6-86268 discloses a device for sticking a ribbon to a body plate of a Patrone, in which a plurality of thin metal plates are in a state where their front ends and rear ends are close to each other, that is, their left ends and right ends are in a line. Each of the velvet is provided with a transporting means for continuously transporting them in a line in a line with each other, and a crimping means for pressing two long velvet ribbons coated with an adhesive respectively to the left and right ends of the transported metal thin plate. After the ribbon is continuously adhered along the left edge and the right edge of the metal thin plate, the long velvet ribbon after the adhesion is divided into each metal thin plate.

Further, in this sticking apparatus, a plurality of cutter units are arranged in an endless chain so as to move synchronously in the same direction as the conveying direction of the thin metal plate on the left and right side portions of the thin metal plate to which the velvet ribbon is stuck. The velvet ribbon is cut by oscillating the cutter of the cutter unit which is moved in a circular motion and is synchronously moved so as to be inserted between the front end and the rear end of the thin metal plate. As a result, the plurality of metal thin plates connected by the velvet ribbon are separated for each metal thin plate.

Thereafter, the divided cartridge shell body plate is formed into a substantially cylindrical shape so that the velvet ribbons overlap each other, and one end of the opening is caulked to form a single-open cartridge. Next, the winding body in which the fixed-size film is wound on the spool is inserted, and finally, the cap is caulked on the other opening of the one-sided cartridge. As a result, the patrone containing the photographic roll film is completed.

In the patrone manufacturing process described above, the working speed of the velvet ribbon attaching process and the assembly process of assembling the patrone are different. Therefore, after the velvet ribbon is attached to the patrone body plate, the patrone body plate is temporarily accumulated in the storage case. To be done. In addition, when accumulated in the storage case, the good product and the defective product are sorted by the sorting device, the good product is dropped in the good product storage case, and the defective product is dropped in the bad product storage case and stacked.

As such a distribution device, Japanese Patent No. 310 is used.
The distribution device disclosed in Japanese Patent No. 9777 is mainly composed of a spider arm conveyor. Each arm of the spider arm conveyor is provided with a magnet that attracts the patrone shell plate. By moving these arms in synchronization with the bucket conveyor, the patrone shell plates that have been conveyed one by one on the bucket conveyor are The magnets on the arm are sequentially attracted and held. Then, while the arm is moving in the non-linear part, the Patrone body plate is checked for good or bad by an inspection device such as a TV camera, and if it is a good product, the arm with the Patrone body plate adsorbed is put into a good product storage case. The product is conveyed to the container, and the non-defective Patrone body plate is dropped into the non-defective product storage case and accumulated. In the case of a defective product, the arm on which the cartridge plate is sucked is conveyed toward the defective product storage case, and the defective product cartridge plate is dropped and accumulated in the defective product storage case.

Explaining the stacking device of Japanese Patent No. 2829764, the boat-shaped patrone shell plate discharged from the telemp ribbon sticking machine to the chute is once conveyed in a horizontal state by a belt conveyor, and the magnet positioned downstream thereof. Adsorbed almost straight to the pulley. Since magnets are embedded in the outer periphery of this magnet pulley, the boat-shaped Patrone body plate moves in a standing posture as the magnet pulley rotates. A magnet is fixed below the belt stretched around the magnet pulley, and belts are also provided on both sides of the boat-shaped Patrone body plate. Therefore, the boat-shaped Patrone body plate, which is separated from the magnet pulley, is sent while being sandwiched by the belts on both sides, so that it advances in the direction of travel without losing its standing posture, and then piles up in sequence. In addition, the boat-shaped Patrone body plate stacks correctly because the bent side is closely attached to the side belt.

[0014]

However, in the conventional method and apparatus for manufacturing a Patrone body plate, the number of products per unit time is large, but the equipment becomes large,
There was a drawback that the mechanism became complicated.

Therefore, the conventional apparatus is not only expensive, but also has a heavy maintenance load for keeping the equipment in a good condition. In addition, there is a problem that the number of nonstandard products (defective products) generated in a transient state at the time of starting and ending also increases.

On the other hand, the demand for photographic film has increased rapidly in recent years even in so-called developing countries, and the market has spread to the world. Also, demands from the market are diversifying even in so-called developed countries. Along with this, it has become necessary to carry out mass production of a limited variety of products in the past, and to produce a wide variety of products in small quantities in a place close to the market.

Therefore, there is a need for a manufacturing apparatus and a manufacturing method thereof which are small in size, inexpensive, simple in mechanism, and easy in maintenance even if the number of products manufactured per unit time is small. On the other hand, the conventional apparatus and manufacturing method cannot sufficiently meet the above reasons.

Further, in the conventional manufacturing apparatus, since the process of bending the thin plate is subdivided, the number of stations is increased, the installation area is widened, and high-speed mass production is aimed at. Therefore, an expensive mechanism is required.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a method and apparatus for manufacturing a Patrone body plate that is small, inexpensive, has a simple mechanism, and is easy to maintain.

[0020]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a means for conveying a thin metal plate cut from a thin plate supply station so that the vertical and horizontal dimensions are the same as the developed vertical and horizontal dimensions of the cartridge plate.

It was realized. That is, the small-diameter bending station is a station that processes one end of the thin metal plate with the thin metal plate positioned, and the goby bending station also processes the other end of the thin metal plate with the thin metal plate also positioned. It is a station. In short, even if the small-diameter bending station and the goby bending station are integrated, since each station processes different parts of the thin metal plate, the devices of each station do not interfere with each other and there is no hindrance to integration. . Further, since the small-diameter bending and the goby bending are simultaneously performed in one positioning, the processing accuracy is also improved.

On the other hand, the corner cutting station is
Since it is a station that cuts the four corners of a thin metal plate into a predetermined shape, it is difficult to integrate it with the small-diameter bending station of the next station because of the interference between the devices. Further, since the both-end bending station is a station for bending both ends of the thin metal plate, it is difficult to integrate the both-end bending station and the goby bending station due to the interference between the devices.

Therefore, according to the present invention in which the small-diameter bending station and the goby bending station are integrated, not only the equipment is downsized, but also the small-diameter bending and the goby bending are performed at the same time by one positioning, so that the processing accuracy is improved.

It is driven by the eccentric rotation operation of these eccentric cam members. As described above, since the present invention employs the eccentric cam member having a simple structure, the structure is simpler and the equipment is simpler than the grooved cam having the complicated structure having the modified sine cam curve.

According to a fourth aspect of the present invention, there is provided a transporting means for continuously transporting a plurality of thin metal plates in a state where the front end and the rear end are close to each other, that is, the left ends and the right ends are aligned. A crimping means for pressing the two long velvet ribbons coated with the adhesive against the left and right ends of the thin metal plate being conveyed is provided, and each velvet ribbon is attached along the left end and the right end of the thin metal plate. The tape is continuously adhered, and the head portion of the cutter unit is linearly reciprocated to cut the long velvet ribbon after the adhesion, which is cut into individual metal thin plates. That is, the cutter unit has its head portion synchronously moved in the same direction as the transport direction of the metal thin plate to which the velvet ribbon is attached,
The heads that are moving synchronously swing in a direction orthogonal to the moving direction. As a result, a plurality of cutters are inserted into the gap between the front end and the rear end of the adjacent thin metal plates,
The velvet ribbon is cut at the same time. After that, the head portion linearly moves to the original position, and the cutting operation described above is repeated. As described above, in the present invention, a structure in which the head unit of the cutter unit is linearly reciprocally moved is adopted instead of the structure in which the cutter unit is revolved by the endless chain. Compact and simple structure.

The invention according to a fifth aspect is characterized in that a sorting station having a small and simple structure in which a plurality of suction means are fixedly arranged in the circumferential movement direction of the belt conveyor is adopted. According to this sorting station, the Patrone body plate is sucked via the belt of the belt conveyor by the suction means arranged on the upstream side of the belt conveyor,
Then, by the revolving movement of the belt conveyor, it is adsorbed from the upstream adsorption means to the adjacent adsorption means, by repeating this adsorption transfer operation from the upstream adsorption means to the downstream adsorption means, the belt conveyor The patrone body plate is conveyed in the orbiting direction. And good
When sorting defects, the control unit controls ON / OFF of the suction unit located above the cartridge stacking unit of the cartridges among the plurality of suction units based on the good / defective information. As a method of sorting, there is a method in which when the cartridge body plate is a defective product, the suction means is turned off, and the cartridge body plate is dropped into a defective product accumulating portion and accumulated. There is also a method in which when the cartridge board is a non-defective product, the suction means is turned off, and the cartridge board is dropped into a non-defective product accumulating portion to accumulate.
That is, the patrone body plate can be sorted into good and bad by a simple control such that the suction means is turned off.

It is inspected whether or not the printing is suitable for the product type. In the case of printing different from the set product type, an alarm is issued to the operator and the product is discharged as a defective product on the downstream side. Further, the shape of the passing metal thin plate 30 is inspected by an optical non-contact sensor, and it is confirmed whether or not the metal thin plate 30 is normally molded. In the case of abnormality, it is similarly discharged as a defective product on the downstream side.

In the case of abnormality, an alarm is given to the operator and the defective metal thin plate 30 is discharged to the NG chute 48 shown in FIG. Further, as another means, when defective products are continuously generated a certain number of times or more, the manufacturing apparatus 10 is stopped and the operator waits for treatment.
This is to satisfy both the requirements of not lowering the operating rate of the equipment and of not continuously producing a large number of defective products.
In FIG. 3, reference numeral 50 is OK for accumulating non-defective products.

The cam follower 275 operates the positioning pin 268 on the cutter unit 74 side.

The cam follower 274 is connected to the L-shaped arm 278 which constitutes the horizontal swing mechanism 276 shown in FIG. The arm 278 has a shaft 27 attached to the corner.
A slide connecting portion 280, which is swingably provided around the fulcrum 9 and is attached to an upper portion of the arm 278, is slidably supported by the inverted concave connecting portion 283 of the horizontal moving table 282. This causes the arm 278 to move to the axis 2
When the horizontal movement table 282 is swung in the arrow direction with 79 as a fulcrum, the horizontal movement table 282 is pushed by the sliding connection portion 280 of the arm 278 and reciprocates in the direction orthogonal to the transport direction of the thin metal plate 30.

A shaft 287 of a swing arm 286 is provided above the horizontal moving table 282 via a bearing 284.
Is supported. The swing arm 286 is arranged in the horizontal direction, and a pin 288 is fixed to the tip of the swing arm 286 downward. The pin 288 is engaged with a groove 291 formed parallel to the metal sheet transport direction of the guide member 290 arranged on the first table 218 as shown in FIG.

Therefore, when the arm 278 is swung counterclockwise around the shaft 279 as a fulcrum in FIG. 23 by the horizontal swing mechanism 276 shown in FIG. 23 by the operation of the cam 244 shown in FIG. The arm 286 moves leftward in FIG. At this time, the first table 21
Since 8 is moved in parallel with the sheet metal conveyance direction, the swing arm 286 moves substantially leftward in FIG. 23 while swinging about the shaft 287 as a fulcrum. When the swing arm 286 moves in this direction, the first table 218
Is pushed by the pin 288 and moves leftward in FIG.
As a result, the base 216 approaches the bucket conveyor 42, and the positioning pin 268 fixed to the base 216,
268 are holes 292 formed in the side surface of the bucket 46,
292 ... is fitted. By this operation, the base 216
Are positioned with respect to the bucket 46. That is, the cutters 212, 212 ... Are positioned with respect to the thin metal plates 30, 30 ... Mounted on the buckets 46, 46.
Since the tapered surface is formed at the tip of the positioning pin 268 and the inlet edge of the hole 292, when the position of the base 216 is deviated from the bucket 46, the tapered surfaces come into contact with each other. When the positioning pin 268 is pushed in, the base 216 is moved by a small amount in the metal thin plate conveyance direction, and is automatically positioned with respect to the bucket 46. The minute movement of the base 216 at the time of positioning can be performed by a linear motion guide provided between the second table 220 and the pedestal 226.

On the other hand, the displacement prevention member 270 is shown in FIG.
Is operated by the cam 246 shown in FIG. The cam 246 has a link 294 that moves up and down by the rotation operation of the cam 246.
Is connected, and the upper end of the link 294 is bifurcated,
The cam follower 296 is attached to one side and the cam follower 297 is attached to the other side. The cam follower 296 operates the position shift prevention member 270 on the cutter unit 72 side, and the cam follower 297 controls the position shift prevention member 2 on the cutter unit 74 side.
70 is operated.

As shown in FIG. 23, the cam follower 296 is a lower engaging recess 2 of the rod 298 which is vertically provided upright.
99 is engaged. The rod 298 is engaged with the second table 220 and is reciprocally moved together with the second table 220 in the sheet metal sheet transport direction. At this time, the lower engaging recess 299 of the rod 298 is guided by the cam follower 296 to reciprocate.

A stopper plate 30 is provided on the upper end of the rod 298.
0 is attached, and the cam follower 302 is pressed against the lower surface of the stopper plate 300 by the urging force of a tension spring (not shown). The cam follower 302 is fixed to the right end portion of the position shift prevention member 270 in FIG. 23, and the position shift prevention member 270 is swingably supported by the base 216 via the shaft 304 at a substantially central portion. In addition, at the left end of FIG.
6, 306 ... Are formed downward.

Therefore, when the rod 298 is moved upward by the operation of the cam 246 shown in FIG. 22, the position deviation preventing member 270 is interlocked with the movement of the rod 298 and is moved by the biasing force shown in FIG.
3 is rotated counterclockwise around the shaft 304 as a fulcrum. By this operation, the pressing claws 306, 306, ... Of the displacement prevention member 270 are moved downward toward the metal thin plates 30, 30, ... Which are to be cut, and these metal thin plates 30, 30. Hold down. As a result, the metal thin plates 30, 30 ... By which the velvet ribbons 54 are cut by the cutters 212, 212 ... Are pinched by the pressing claws 306 and the bucket 46.
The displacement of the metal thin plate 30 with respect to the bucket 46 is prevented. Therefore, the metal thin plate 30 is accurately positioned on the bucket 46 by the displacement prevention member 270 and the positioning pin 268 described above, and then the cutter 21.
The velvet ribbon 54 is cut by 2, 212, ....

Next, the cutting operation of the cutter unit 72 configured as described above will be described.

First, the cutting start position of the cutter unit 72 is the position where the head 210 is arranged on the upstream side in the metal sheet transport direction, and the position where the head 210 is retracted from the bucket conveyor 42 as shown in FIG. In addition, as shown in FIG. 23, the head 210 is a position retracted downward from the cutting position of the velvet ribbon 54, and further, the pressing claw 306 of the displacement prevention member 270 is retracted upward from the pressing position of the thin metal plate 30. Is.

Next, when the cutting operation is started, the head 210 moves synchronously from the cutting start position by the forward movement of the index unit 112 in the same direction as the transport direction of the metal thin plate 30 by the bucket conveyor 42. Then, when the moving speed of the head 210 is accelerated to the metal thin plate conveying speed, that is, immediately before the velvet ribbon 54 is cut by the cutters 212, 212, the base 216 is operated by the cam 244, and the base 216 is moved. Is moved toward. As a result, the positioning pin 268 is fitted into the hole 292 of the bucket 46, and the cutters 212, 212 ...
Are positioned with respect to the metal thin plates 30, 30.

Further, in synchronization with this operation, the position deviation prevention member 270 is operated by the cam 246, and the metal thin plate 3
0, 30, ... Are clamped by the pressing claw 306 and the bucket 46. As a result, the metal thin plate 30 is accurately positioned on the bucket 46 by the displacement prevention member 270 and the positioning pin 268.

After that, the head 210 swings about the shaft 214 in the direction orthogonal to the transport direction of the thin metal plate 30 by the upward movement of the rod 252 by the operation of the cam 240.
As a result, the cutters 212, 212 ... Are inserted into the gap between the front end and the rear end of the thin metal plates 30, 30 ... While being conveyed, so that the velvet ribbon 54 is cut at the same time.

When the cutting of the velvet ribbon 54 is completed,
The displacement prevention member 270 is operated by the cam 246, the pressing claw 306 is moved away from the thin metal plates 30, 30, ..., The base 216 is operated by the cam 246, and the positioning pin 268 is moved to the hole 292 of the bucket 46.
Move away from.

After that, the head 210 is moved from the downstream position to the upstream position by the backward movement of the index unit 112.
Is moved linearly. Then, the head 210 is swung to the position retracted downward from the cutting position of the velvet ribbon 54 by the downward movement of the rod 252 due to the operation of the cam 240. The cutter unit 72 returns to the cutting start position by the above operation. Then, the velvet ribbon 54 is continuously cut by repeating the above-described operation.

Next, the OK / NG sorting / collecting device 16 will be described with reference to FIGS.

This OK / NG sorting / collecting device 16 is shown in FIG.
As shown in FIG. 5, it mainly comprises a magnet conveyor 76. The magnet conveyor 76 includes a pair of pulleys 31.
The belt 77 is stretched by 0, 312, and is revolved in the direction of the arrow, and seven magnets (adsorption means) 78A to 78G are arranged along the revolving direction of the belt 77. Further, of the magnets 78A to 78G, the magnet 7
8A, 78D, 78E, 78F and 78G are permanent magnets, and magnets 78B and 78C are turned on by the CPU 308.
It is an electromagnet that is controlled to be turned off. These magnets 78A
.About.78G is set to a size and an interval such that the thin metal plate 30 is not attracted by the three magnets at the same time.

Next, the operation of the OK / NG sorting / collecting device 16 will be described.

The thin metal plate 30 conveyed by the bucket conveyor 42 is passed through the belt 77 and the permanent magnet 7 on the upstream side.
It is picked up from the bucket conveyor 42 by being sucked by 8A. In addition, in the vicinity of the permanent magnet 78A,
A non-contact sensor (not shown) that detects whether or not the thin metal plate 30 is attracted by the permanent magnet 78A is provided.

The thin metal plate 30 is attracted to the adjacent electromagnet 78B from the upstream permanent magnet 78A by the revolving movement of the belt 77, and this attraction / transfer operation is directed from the upstream magnet 78A to the downstream magnet 78G. By repeating the above, the metal thin plate 3 is moved in the orbiting direction of the belt 77.
0s are conveyed one by one.

The carrying speed of the belt 77 is set higher than the carrying speed of the bucket conveyor 42. Therefore, the metal thin plates 30 that have been conveyed on the bucket conveyor 42 at a slight distance from each other have a wider distance between the metal thin plates 30 at the front and rear when they are sucked and conveyed by the belt 77. This interval is determined by the speed ratio between the belt 77 and the bucket conveyor 42. If the belt 77 has a speed twice that of the bucket conveyor 42, for example, the same interval as the width of the thin metal plate 30 will be opened.

Here, there are two purposes for separating the front and rear metal thin plates 30 from each other. The first is that when the metal thin plate 30 is loaded from the belt 77 to the OK chute 50 or the NG chute 48, stable loading can be performed without causing interference with the front and rear metal thin plates 30. The second is a velvet ribbon 5 attached to the thin metal plate 30.
By cutting 4 with the ribbon cutting mechanism 72, the metal thin plate 30 is separated into individual metal thin plates 30.
Is to detect. That is, when the metal thin plates 30 connected by failing to cut the ribbon 54 are attracted to the belt 77 by the permanent magnet 78A, even if the metal thin plate 30 is conveyed by the belt 77 that is faster than the bucket conveyor 42, the ribbon 54 will not be conveyed. Subsequent metal sheets 30 connected
However, since it is still placed on the low-speed bucket conveyor 42, the belt 77 does not reach the speed of the belt 77 and slips and is delayed. At this time, the sensor for detecting whether or not the above-mentioned metal thin plate 30 is normally adsorbed is detected by the metal thin plate 3 at a normal timing.
It can be seen that 0 is not detected and is in an abnormal state. In this case, the thin metal plate 30 is defective. The subsequent connected thin metal plates 30 are also treated in the same manner.

During this conveyance, a control signal from the CPU 308 which has tracked the signal based on the pass / fail information generated by the inspection result of the metal thin plate inspection means installed in the metal thin plate conveying path up to this point, Electromagnet 78B, 7
By controlling ON / OFF of 8C, good products and defective products are sorted. That is, the electromagnets 78B and 78C provided above the NG chute 48 are de-energized by the CPU 308 when a defective product arrives at that position. As a result, the defective product is dropped onto the NG chute 48. In this way, the two electromagnets 78B and 78C are turned off.
By doing so, the defective product can be dropped onto the NG chute 48 before the defective product is attracted to the permanent magnet 78D. In the vicinity of the permanent magnet 78D, a non-contact type sensor (not shown) for detecting whether or not the metal thin plate 30 is attracted by the permanent magnet 78D is provided, and the sensor detects a defective metal thin plate 30. When it is detected that the magnet is attracted to the permanent magnet 78D, the control unit determines that it is abnormal and stops the magnet conveyor 76.

The reason why the inspection so far is determined to be a defective product is that when the temperature of the thin metal plate 30 immediately before entering the pressing portion 64 is outside the temperature range in which good adhesion can be obtained, the adhesion is performed. If the amount of protrusion of the velvet ribbon 54 from the metal thin plate 30 due to misalignment with the metal thin plate 30 is outside the range where good light-shielding performance is obtained, the velvet ribbon 54 is turned upside down. When detecting a part where the velvet ribbon 54 is self-adhesive and doubled, or when it is detected that there is no adhesive that should have been applied to the velvet ribbon 54, the thin metal plate 30 When the deviation from the correct shape is detected, when the printing of the metal thin plate 30 is different from the set printing, the ribbon cutting is not successful and a plurality of metal thin plates 30 are connected. If there is such.

On the other hand, the OK chute 50 is separated from the permanent magnet 78G arranged at the most downstream position by a predetermined distance (width of one thin metal plate 30) on the downstream side in the conveying direction.
It is located below. When the OK chute 50 is arranged below such a separated position S, the good product of the metal thin plate 30 conveyed to the separated position S drops from the belt 77 to the OK chute 50 due to the decrease in the magnetic force of the permanent magnet 78G. As a result, the thin metal plates 30 are sorted into good and bad ones and accumulated.

As described above, according to the OK / NG sorting / collecting device 16 of the embodiment, a plurality of magnets 78A to 78G are fixedly arranged in the orbiting direction of the belt 77, and these magnets 78 are arranged.
Among the A to 78G, the electromagnets 78B and 78C located above the NG chute 48 are controlled by the CPU based on the good / bad information.
The thin metal plate 30 is controlled by controlling the ON / OFF of 308.
Therefore, it is possible to provide the OK / NG sorting / collecting device 16 having a small size and a simple structure.

By the way, the non-defective metal thin plate 30 is dropped onto the OK chute 50 of FIG. 12A constituting the integrated device with the goby side (end 30C side) facing downward.

The OK chute 50 is inclined at a predetermined angle, and its width is made substantially the same as the width of the thin metal plate 30.
The thin metal plate 30 slides down the OK chute 50 with the goby side down, but the lower end portion 51 of the OK chute 50.
12 is formed horizontally as shown in FIG. 12B, the metal thin plates 30 in the lying posture are already attached to the metal thin plates 30.
When the goby portion of the metal thin plate 30 that has slid off as shown in (c) comes into contact, the metal thin plate 30 in the lying position stands up due to the pushing force exerted by the contact, and as a result, the horizontal portion 51.
It is accumulated in a standing posture with the goby part down. The inclination angle of the OK chute 50 that brings about such an action is 20 ° to
Although it is in the range of 45 °, it is preferably set in the range of 30 ° to 35 ° corresponding to the production speed. The thin metal plate 30 accumulated on the OK chute 50 is bent into a cylindrical shape in the next step to be a Patrone body plate.

The integrated device of the embodiment has FIGS.
The accessory devices shown in are provided individually or integrally.

As an example of incidental equipment, an OK chute 50
A belt conveyor 320 for increasing the feeding speed is installed at the entrance portion 50A of the. A magnet 322 is arranged on the back side of the belt 323 of the belt conveyor 320,
The belt 323 strengthens the force for holding the thin metal plate 30 by suction. Further, the belt 323 is rotated by the driving force from the motor 324 in the direction in which the thin metal plate 30 delivered to the belt 323 is sent to the OK chute 50. This allows the OK shoot 50 from the belt conveyor 320.
The thin metal plate 30 is reliably delivered at high speed.

On the other hand, when the thin metal plate 30 slipping off the OK chute 50 collides with the thin metal plate 30 accumulated in advance and the goby portion engages and rises up, if the speed is too high, the metal becomes too strong. In some cases, the upper portion of the thin plate 30 may pop out, and clean accumulation may not be possible. Therefore, the pop-out prevention guide 340 is installed on the inclined portion of the OK chute 50.

Horizontal part (lower end) 51 of the OK chute 50
, Are stacked in the standing position with the goby portion downward, and the thin metal plates 30, 30, ... Are accumulated, and if the processing amount is small, the operator appropriately takes them out.

However, when it is desired to increase the amount to be accumulated, for example, when the processing amount is large, the accumulating conveyor 350 is provided below the horizontal portion 51 which is the exit of the OK chute 50, and the accumulating conveyor 350 has an arrow A in FIG. By the orbital movement indicated by, the thin metal plates 30, 30 ... Collected on the horizontal portion 51 are sent to the discharge side. In this case, a movable stopper 352 that moves along the horizontal portion 51 is provided, and the metal thin plate 30 catches up with the preceding metal thin plate 30 and stands up at a substantially constant position.
When the stopper 352 is retracted little by little (in the flow of the body plate, the stopper 352 moves in the downstream direction), stable accumulation becomes possible. As a drive mechanism of the stopper 352, a feed screw device 354 can be applied as shown in FIG. In this case, the stopper 352 is fixed to the nut portion 356, the nut portion 356 is screwed onto the feed screw 358, and is engaged with a linear guide not shown. As a result, when the feed screw is rotated in the normal direction or the reverse direction by a motor (not shown), the stopper 352 moves to the horizontal portion
Move back and forth along.

Furthermore, when it is desired to automate the work of transferring the finished metal thin plate 30 to the downstream process using a tray or the like, the transfer device 360 may be provided on the stacking conveyor 350. The operation of the transfer device 360 will be described. The movable stopper 352 catches the thin metal plates 30 sliding down the OK chute 50, and collects them at the standing position with the goby part down.
Although the movable stopper 352 moves backward toward the discharge side, the sensor 362 for counting the number of thin metal plates is in the middle of the horizontal portion 51.
It is provided in. When the movable stopper 352 retracts to a predetermined position, it can be estimated that a substantially constant number of thin metal plates 30, 30, ... Are stacked between the partition plate 364 and the movable stopper 352. At that time, the partition plate 364 divided into two is arranged so that the rod 36 of the cylinder 366 is moved from above the horizontal portion 51.
It is moved toward the horizontal portion 51 by the extension operation of 8, and is inserted between the accumulated metal thin plates 30, 30. Since the accumulated metal thin plates 30, 30 ... Are in contact with each other by the upper and lower ribbons, there is a gap between the two metal thin plates 30, 30 themselves, and the partition plate 364 has a tapered portion with a thin tip. Since it has, the partition plate 364 can be easily inserted between the integrated metal thin plates 30, 30.

Therefore, by interlocking one side 364A of the partition plate 364 divided into two and the movable stopper 352 in the discharging direction as shown in FIG. 27, a predetermined number of the accumulated thin metal plates 30, 30, ... Are cut out. . Because of the two partition plates 364, a gap is created between the partition plate 364 and the subsequent metal thin plate 30,
A predetermined number of thin metal plates 3 with a transfer device such as a robot hand
Just take out 0, 30 ...

The taken-out thin metal plates 30, 30 ... Are put in a tray for supplying to the downstream process. After that, the one partition plate 364A paired with the movable stopper 352 returns to the original position, the partition plate 364 retracts, and the accumulated metal thin plates 30, 30 ... Come to the movable stopper 352 for accumulation. to continue. A feed screw device may be adopted as the moving device of the one partition plate 36A.
