Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for distributing patrone body plates, and particularly to a patrone body plate to which a light-shielding telem is attached in a manufacturing process of a patrone body plate for storing a photographic roll film. The present invention relates to a sorting device that sorts defective products.

[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.

Then, the shell plate of the cartridge is bent into a substantially cylindrical shape so that the velvet ribbons overlap each other, and a cap is caulked at one of the opening ends to form a cartridge with one opening. 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 above-mentioned patrone manufacturing process, since the working speed of the velvet ribbon attaching process and the assembling process of assembling the patrone are different, the patrone body plate is temporarily accumulated in the storage case after the velvet ribbon is adhered. 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.

[0007]

However, the conventional device for distributing patrone body plates is a spider arm conveyor composed of a plurality of moving arms, and therefore has the drawbacks that the device becomes large and the structure becomes complicated. It was

The present invention has been made in view of the above circumstances, and an object thereof is to provide a distribution device for a Patrone body plate having a small size and a simple structure.

[0009]

In order to achieve the above-mentioned object, the present invention provides a sorting device for sorting the patrone shell plate conveyed by the conveying means into a good product or a defective product based on the good / bad information. The distributing device is fixedly arranged at a predetermined interval in the orbiting direction of the belt conveyor and a belt conveyor installed on the downstream side of the conveying means, and has been conveyed to the downstream side of the conveying means. A plurality of adsorption means for adsorbing the cartridge board through the belt of the belt conveyor, a cartridge board stacking section composed of a good product stacking section and a defective product stacking section arranged below the belt conveyor, and the plurality of suction boards Control means for controlling ON / OFF of the suction force of the suction means located above the cartridge body plate accumulating portion of the means based on the good / bad information. It is characterized in that there.

The invention according to claim 1 is characterized in that a sorting device having a small and simple structure in which a plurality of suction means are fixedly arranged in the direction in which the belt conveyor is rotated is adopted. According to this sorter, the cartridge plate is adsorbed via the belt of the belt conveyor by the adsorbing means arranged on the upstream side of the belt conveyor, and by the circular movement of the belt conveyor, the adsorbing means on the upstream side. From the adsorbing means adjacent to the adsorbing means, and the adsorbing and transferring operation is repeated from the adsorbing means on the upstream side to the adsorbing means on the downstream side, so that the cartridge plate is conveyed in the revolving direction of the belt conveyor. Then, in order to sort good / bad, the control means controls ON / OFF of the suction means, which is located above the cartridge body plate accumulating portion among the plurality of suction means, based on the good / bad information. As a distribution method, there is a method in which when the cartridge body plate is defective, the suction means is turned off and the cartridge body plate is dropped and accumulated in the defective product accumulating portion. 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.

According to the third aspect of the present invention, the non-defective product stacking unit of the cartridge stacking unit of the cartridge is arranged below the separated position which is separated from the suction means arranged at the most downstream position by a predetermined distance downstream in the transport direction. It is characterized by being When the non-defective product accumulating section is arranged below such a separating position, the non-defective product of the cartridge board conveyed to the separating position falls from the belt conveyor to the non-defective product accumulating section due to the lowering of the suction force of the suction means.
Therefore, without controlling the suction means ON / OFF,
Good quality Patrone body plates can be accumulated in the good quality accumulation unit.

According to a fourth aspect of the invention, a magnet is applied as the attraction means. Further, an electromagnet is applied as a magnet located above the cartridge stacking section of the cartridge, and the electromagnet is ON / OFF controlled by the control means.

The upper end of the rod 176 is rotatably supported via a pin 182 on the left end of a work holding arm 180 pivotally supported by a pin 178 near the lower mold 23A shown in FIG. A pressing portion 181 is formed on the right end of the work pressing arm 180, and the pressing portion 181 presses the metal thin plate 30 placed on the lower mold 23A against the lower mold 23A to position it.

Therefore, when the shaft 154 rotates, the rod 176 moves up and down by the eccentric rotation action of the eccentric cam 130. By the downward movement of the rod 176 at this time, the work holding arm 180 swings counterclockwise in FIG. 15 about the pin 178, and the work holding portion 181 is pressed.
Is retracted above the lower mold 23A, and the thin metal plate 30 on the upstream side is conveyed to the small-diameter bending station / goby bending station 22 by the feed pitch movement of the feed bar 28. Then, as the rod 176 moves upward, the work holding arm 180 swings clockwise around the pin 178 in FIG. 15, and the holding portion 181 holds the thin metal plate 30 against the lower die 23A. As a result, the metal thin plate 30 is positioned on the lower mold 23A.

In the exen cam 132 shown in FIG. 7, a bearing 184 in which grease is pre-enclosed is used.

Therefore, when the shaft 154 rotates, the rod 196 moves up and down by the eccentric rotation action of the eccentric cam 134. By the downward movement of the rod 196 at this time, the angling arm 200 swings counterclockwise in FIG. 15 about the pin 198, and the pointed portion 201 moves above the lower mold 23A as shown by the chain double-dashed line in FIG. The metal thin plate 30 on the upstream side is conveyed to the small-diameter bending station / goby bending station 22 by the feed pitch movement of the feed bar 28. Then, as the rod 196 moves upward, the angling arm 200 swings clockwise around the pin 198 in FIG. 15, and the sharp portion 201 collides with the other end portion 30C of the thin metal plate 30 and the other end portion. 30C is bent into an acute angle to form a goby bent portion.

The drive branch gearbox 146 shown in FIG. 7 is provided with a manual handle 147 for moving the device at a very low speed to check the adjustment.

The operation of the small-diameter bending station and the goby bending station 22 will be described. First, as shown in FIG. 21, the small-diameter bending upper die 23 is disposed on the right side in the drawing, and the goby-bending work holding arm 180, The 90-degree folding arm 190 and the angling arm 200 are the upper mold 2
It is arranged on the left side in FIG. That is, the upper die 23 for small-diameter bending and each arm 180, 190, 2 for goby bending
It is arranged at a position where it does not interfere with 00.

In the small-diameter bending station / goby bending station 22 having such an arrangement positional relationship, the thin metal plate 30 is conveyed from the upstream side to the lower die 23A. The thin plate transport rails in this portion are separated to form a lower mold 23A and a vertically movable lifter 22A embedded therein. First, the work pressing arm 180 retracted above the lower mold 23A moves downward (swings clockwise in FIG. 15), and the metal thin plate 30 is moved downward by the pressing part 181 as shown in FIG. 23A and press the metal thin plate 30 into the lower mold 23

Can be formed with.

By the way, the distribution device 16 of the embodiment is
As shown in FIG. 22, mainly the magnet conveyor 76
Consists of. The magnet conveyor 76 is a pair of pulleys 2.
The belt 77 is stretched by 12 and 214 and revolves in the direction of the arrow, and seven magnets (adsorption means) 78A to 78G arranged along the revolving direction of the belt 77. Further, among the magnets 78A to 78G, the magnets 78A, 78D, 78E, 78F, and 78G are permanent magnets, and the magnets 78B and 78C are turned on by the CPU 210.
It is an N / OFF controlled electromagnet. These magnets 78
A to 78G are set to sizes and intervals such that the thin metal plate 30 is not attracted by the three magnets at the same time.

Next, the operation of the distribution 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 orbital 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 of 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, the electromagnet 78 is controlled by the control signal from the CPU 210 which has tracked the signal based on the quality information generated as a result of the inspection so far.
By controlling ON / OFF of B and 78C,
Sort defective products. That is, the electromagnets 78B and 78C provided above the NG chute 48 are de-energized by the CPU 210 when a defective product arrives at that position. As a result, the defective product is dropped onto the NG chute 48. In this way, by turning off the two electromagnets 78B and 78C, the defective product can be dropped onto the NG chute 48 before the defective product is attracted to the permanent magnet 78D. In addition, in the vicinity of the permanent magnet 78D, the permanent magnet 78D
Is provided with a non-contact sensor (not shown) for detecting whether or not the metal thin plate 30 is adsorbed, and this sensor detects that the defective metal thin plate 30 is adsorbed by the permanent magnet 78D. In that case, the control unit determines that there is an abnormality and stops the magnet conveyor 76.

The reason why it is determined as a defective product in the inspection so far is that when the temperature of the thin metal plate 30 immediately before entering the pressurizing portion 64 is outside the temperature range in which good bonding can be obtained, the bonding 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 that the velvet ribbon 54 is adhered by itself to form a doubled portion, 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 is 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 distribution device 16 of the embodiment, the plurality of magnets 78A to 78A are arranged in the direction in which the belt 77 is rotated.
78G is fixedly arranged, and among these magnets 78A to 78G, electromagnets 78B and 7 located above the NG chute 48.
8C, CPU210 turns on / off based on good / bad information
Since the thin metal plates 30 are distributed by the OFF control, the distribution device 16 having a small size and a simple structure can be provided.

By the way, the non-defective metal thin plate 30 is shown in FIG.
On the OK shoot 50 shown in (a), on the goby side (end 30C)
Side) is turned down.

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.

Metal thin plate 3 integrated on OK chute 50
In the next step, 0 is bent into a cylindrical shape and manufactured into a patrone body plate.

In the embodiment, a magnet is used as the attraction means, but the invention is not limited to this. For example, when the belt 77 is a porous belt, the metal thin plate 30 can be attracted and held by air suction, In this case, the suction pad can be applied as the suction means.

The control means turns ON / OFF the suction means located above the stacking unit based on the good / bad information.
Since the Patrone body plate is distributed by controlling it,
It is possible to provide a small-sized and simple-structure sorter.
