To be done. When a defective can is found, the defective can is collated with the corresponding inspection result to investigate the cause of the defect, and based on the investigation result, the adjustment and improvement of the can barrel manufacturing process are performed. Is done.

[0004]

However, if the can barrel that has been removed from the production line as a defective can is actually seen, in particular, when one can barrel has a plurality of defects, which one is defective. I couldn't instantly determine if it had been done. If defective cans are arranged in the order in which they were inspected, it is possible to investigate the contents of defects in each defective can based on the inspection records of the surface inspection device. It is difficult to store defective cans that are discharged in a box or the like.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an inspection result identification device capable of easily obtaining an inspection result from an inspection object which has been inspected. .

[0006]

A storage device that stores the inspection result of the inspection object on the stage, a marking device that gives the inspection result or a signature indicating the inspection result to the inspection object that has been inspected, and the inspection result by receiving the information of the inspection result from the storage device. It is characterized by having a control device for controlling the operation of the marking device so that a corresponding inspection result or a signature indicating the inspection result is given to the completed inspection object.

In the inspection result identification device thus constructed, a marking device is provided for giving an inspection result or a signature indicating the inspection result to the inspection object which has been inspected, and the inspection object at each inspection stage is stored by the storage device. The inspection result of the object is stored, the operation of the marking device is controlled by the control device based on the inspection result stored in the storage device, and a corresponding inspection result or a signature indicating the inspection result is given to the inspection object. To be done. As a result, the inspection result corresponding to the inspection object itself or a signature indicating the inspection result is added. The inspection result here is, for example, information such as whether or not there is a defect, the type of the defect, and in which inspection stage the defect was found, and the signature indicating the inspection result is, for example, ○ or ×. In addition to the symbols and numbers, those that show the inspection result by the color of these symbols and numbers, or the position where these symbols and numbers are given are also included. As a marking device used in this inspection result identification device, for example, a stamp type device,
It is possible to use an arbitrary structure such as a system in which ink or the like is ejected to the inspection object to provide an inspection result or a signature indicating the inspection result.

Here, in the inspection result identifying apparatus according to the present invention, a sorting mechanism is provided which conveys the inspection object, which has been inspected, to different conveying paths for the non-defective product and the defective product so that the marking device can detect the defective product. The inspection result or the signature indicating the inspection result may be added only to the inspection object conveyed toward the conveyance path. In this case,
Since the inspection result or the signature indicating the inspection result is given only to the defective product and not to the good product, the appearance of the good product is not damaged. Further, the marking device may be configured to have a stamp and an advancing / retreating mechanism for advancing / retreating the stamp toward / from the inspection object. In this case, the marking device can have a simple structure, and the manufacturing cost of the inspection result identification device can be reduced and the maintainability can be improved.

A sorting mechanism 6 is provided for sending defective cans to the second conveying path 6b independent of the production line.

The supply side turret 4 holds the can body C introduced from the previous step at a plurality of positions on the outer circumference,
The can body C is intermittently rotated by a predetermined angle and is delivered intermittently to the carrying side turret 5. Here, the supply side turret 4 holds the outer peripheral surface of the can body C. The transport-side turret 5 is intermittently rotated by a predetermined angle, and a plurality of substantially disk-shaped rotary pedestals D are provided on the outer periphery thereof at substantially equal intervals in the circumferential direction. Each of these rotary pedestals D holds one end in the axial direction of the can body C and is rotatable around the axis of the can body C together with the can body C, and the rotation direction α of the carrier side turret 5 by the carrier side turret 5. To be moved intermittently.

The can body C is sequentially supplied from the supply side turret 4 to the rotary pedestal D as the supply side and transfer side turrets 4 and 5 rotate. Here, among the places where the rotating pedestal D, which is moved intermittently, stays for a while, at least the place where the can body C is transferred from the supply side turret 4 to the rotation direction α side by one or more steps is inspected. It is supposed to be a stage. The present embodiment shows an example in which three inspection stages are provided (the first inspection stage S1, the second inspection stage S2, and the third inspection stage S3 in order from the side close to the supply side turret 4). To). In the surface inspection device 1, the first, second,
The rotary pedestals D carried into the third inspection stages S1, S2, S3 are rotated around the axis of the can body C held by a rotating mechanism (not shown).

One of the two is selectively switched. In the present embodiment, when the can body C is a good can, the holding of the can body C by the delivery side turret 7 is released when the can body C reaches the entrance of the first transport path 6a. The can body C is fed into the first transport path 6a. Also, can body C
Is a defective can, even when the can barrel C reaches the entrance of the first transport path 6a, the holding of the can barrel C by the delivery side turret 7 is not released, and the can barrel C continues to be transported. When reaching the entrance of the second conveyance path 6b, the holding of the can body C is released,
The can body C is fed into the second transport path 6b. The can bodies C sent to the second transport path 6b are stored at the subsequent stage in a state of being arranged in the order sent by the sending-side turret 7.

Inspection result identifying apparatus 11 according to the present embodiment
Is provided in the surface inspection apparatus 1 described above,
A storage device 12 that stores the inspection result of the can body C at each inspection stage determined by the processing device G, and a marking device 13 that gives the inspection result or a signature indicating the inspection result to the can body C that has completed the inspection, A control device 14 that controls the operation of the marking device 13 so that the inspection result corresponding to the inspection result or the signature indicating the inspection result is added to the can body C that has received the inspection result information from the storage device 12 and has been inspected. Have Here, the storage device 12 stores the inspection result of the can body C and the order in which the inspection is performed, and the control device 14 controls the transport side and delivery side turrets 5 and 7 by a sensor or the like (not shown). The intermittent rotation of at least one of the two can be monitored, and based on this information, it can be determined when the can body C conveyed to the marking position M has been inspected at each inspection stage. (The judgment as to when the can body C transported to the marking position M is inspected at each inspection stage can employ any method or means other than the above). The control device 4 may also serve as a control device that controls the holding of the can body C by the delivery side turret 7 of the sorting mechanism 6.

In the present embodiment, the marking device 13
Is a can at a position where the can body C held by the delivery side turret 7 stays for a while and at least one stage is moved to the rotation direction β side from the position where the inlet of the first transport path 6a is installed. The inspection result or a signature indicating the inspection result is given to the body C (this position is referred to as a marking position M). Here, the number of times the delivery side turret 7 rotates intermittently before the can body C delivered to the delivery side turret 7 at the delivery position P is conveyed to the marking position M is N4.

In the present embodiment, the marking device 13
Indicates the stamp 16 and the marking position M on the stamp 16.
And a moving mechanism 17 for moving the can body C forward and backward toward the can body C and impressing the stamp 16 on the can body C, and three stamps 16 (first, second and third stamps 16a,
16b, 16c) are arranged along the axis of the can body C held by the delivery side turret 7. These first, second and third stamps 16a, 16b, 16c
Are the first, second and third inspection stages S1 and S, respectively.
The signatures indicating the inspection results in S2 and S3 are added, and the signatures are held by independent advance / retreat mechanisms 17 (first, second, third advance / retreat mechanisms 17a, 17b, 17c). Here, these first, second, and third stamps 16a, 16b, 16c are simply provided with imprints indicating that the inspection result of the can body C at the corresponding inspection stage is defective. The imprint and the color of the imprint are arbitrary.

The stamp 16 has a construction in which a printing surface is formed at one end of a printing material made of a material capable of penetrating ink (for example, a porous material) and the other end is dipped in an ink reservoir. The ink in the reservoir is constantly supplied to the printing surface through the inside of the printing material, so that the can body C can be repeatedly imprinted. The advancing / retreating mechanism 17 includes, for example, an electromagnetic slider having the stamp 16 attached to the tip thereof, a coil into which the electromagnetic slider is inserted, and a biasing member such as a spring for biasing the electromagnetic slider in the backward direction. And have. When the coil is not energized, the electromagnetic slider is retracted by the urging force of the urging member and the stamp 16
Is not in contact with the can body C located at the marking position M, and the can is located at the marking position M by advancing the electromagnetic slider against the biasing force of the biasing member by energizing and exciting the coil. A stamp 16 is imprinted on the body C.

The operation of the inspection result identification device 11 thus constructed will be described below together with the operation of the surface inspection device 1. In the surface inspection apparatus 1, the can body C is sent to the carrier side turret 5 from the manufacturing process in the previous stage by the carry-in side turret 4, and the can body C is sequentially carried into each inspection stage due to intermittent rotation of the carrier side turret 5. Then, the surface inspection is performed at each inspection stage, and the can bodies C that have undergone the inspection are sequentially carried out toward the sorting mechanism 6. The sorting mechanism 6 sorts good and bad cans based on the inspection result of each can body C, the good cans are sent to the first transport path 6a, and the bad cans are passed through the marking position M. It is sent to the second transport path 6b.

Here, when the can body C inspected in the first inspection stage S1 is a defective can, the transport side and delivery side turrets 5 and 7 are intermittently rotated N1 + N4 times to reach the marking position M. It will be brought in. Similarly, when the can body C inspected in the second inspection stages S2 and S3 is a defective can, the transport side and the delivery side turrets 5 and 7 are intermittently rotated N2 + N4 times and N3 + N4 times, respectively, to mark the marking position. It will be loaded into M. The control device 14 of the inspection result identification device 11 monitors the intermittent rotation of at least one of the transport side turret 5 and the delivery side turret 7, and the inspection stored in the storage device 12 is based on this information. The inspection result at each inspection stage of the can body C transported to the marking position M is specified from the result information. That is, the control device 14 determines, from the storage device 12, the result of the inspection performed N1 + N4 times before in the first inspection stage S1, the result of the inspection performed N2 + N4 times before in the second inspection stage S2, The information of the inspection result performed N3 + N4 times before is obtained in the inspection stage S3.

Based on the information of this inspection result, the control device 14 among the advancing / retreating mechanisms 17 of the marking device 13
Advancing / retreating mechanism 17 corresponding to the inspection stage where a defect is found
Of the can 16 having the stamp 16 corresponding to the inspection stage in which the defect is found carried into the marking position M.
To imprint.

As a result, the imprint showing the inspection stage in which the defect is found is given to the defective can fed into the second conveying path 6b. In the present embodiment, the first, second, and third stamps 16a, 16b, and 16c are arranged along the axis of the can body C held by the delivery side turret 7. Even if the imprint color is the same, it is possible to know which stamp has been imprinted from the stamped position on the can body C (not limited to this, the first, second and third stamps 16a). , 16b,
The stamp imprints of 16c may be different from each other, or the color of the stamp imprint may be changed so that it can be known from the stamp imprinted on the can body C which stamp has been imprinted.

The inspection result identification device 1 configured as described above.
According to 1, since the signature indicating the inspection stage where the defect is found is added to the can body C itself, just by looking at the defective can, it is possible to confirm at which inspection stage the defect was found. You can Thereby, for example, even if there are can bodies C in which defects are found in a plurality of inspection stages, defective cans stored in a state in which they are arranged in the order in which they are sent by the sending-side turret 7 in the subsequent stage of the second transport path 6b. By collating with the record of the inspection result of the defective can, the inspection result of the defective can can be easily obtained. In addition, the marking device 13 gives the signature indicating the inspection result only to the defective can among the can bodies C that have undergone the inspection, and since the signature is not attached to the non-defective product, the appearance of the non-defective product may be impaired. Absent.
Further, since the marking position M is provided at a stage subsequent to the first conveying path 6a, there is no fear that a signature is attached to a non-defective product due to a malfunction or the like. Further, since the marking device 13 has a simple structure including the stamp 16 and the advancing / retreating mechanism 17 for advancing / retreating the stamp 16 toward the can body C, the manufacturing cost of the inspection result identification device 11 is reduced and the maintainability is improved. Can be improved.

In the above embodiment, the example in which the inspection result identification device 11 is provided in the surface inspection device 1 has been described, but the invention is not limited to this, and the inspection result identification device according to the present invention is not limited to the inspection object. Any other inspection device can be used as long as it is an inspection device that inspects an inspection object on each of a plurality of inspection stages provided on the conveyance path. Also,
In the above-described embodiment, the marking device 13 includes the stamp 16 and the advancing / retreating mechanism 17 for advancing / retreating the stamp 16 toward the can body C that has been carried into the marking position M to imprint the stamp 16 on the can body C. However, the present invention is not limited to this, and an arbitrary configuration such as a configuration in which ink is ejected toward the can body C carried in to the marking position M to provide an inspection result or a signature indicating the inspection result can be used. Can be adopted.

In the above embodiment, the stamp 16 is used.
In the above, the seal imprint indicating only the inspection stage in which the defect is found is provided, but the invention is not limited to this. For example, as the stamp 16 corresponding to each inspection stage, the seal imprint is performed according to the content of the corresponding defect. And / or a plurality of stamps 16 having different imprint colors are provided, and the stamp 1 and / or the stamp 1 having the imprint color corresponding to the inspection result are provided.
6 may be imprinted. In this case, it is possible to find out at which inspection stage the defect is found from the imprint imprinted on the can body C and what the content of the defect is. There is no need to check the actual defective cans with the records of the inspection results one by one when conducting an investigation, which saves time and effort for the investigation and eliminates the need to know the order in which defects were found for defective cans. The management of defective cans becomes easy. Also,
In the above embodiment, an example in which the marking position M is provided between the first transport path 6a and the second transport path 6b in the sorting device 6 has been shown, but the marking position M is not limited to this. , The transfer position P and the first transport path 6a
And the marking position M may be provided immediately after the third inspection stage S3. In this case, the ink used for the stamp 16 is normally colorless and transparent and can be visually recognized only when irradiated with ultraviolet rays or the like. It is possible to add a sign indicating.
