Canned sample revealed in the issue details! Machine-like container sample Ml
jl is effective in detecting defects in printed metal can members. A can testing device such as the one disclosed in the above-mentioned U.S. patent can test for the presence of ink printed on a can and the presence of defects in can body members such as cracks and bottle holes. To reduce the scrap rate, or the number of cans discarded by the can tester, it is helpful to monitor the operation of the can tester to identify possible can manufacturing process problems and can test #ti problems. It is. For example, are there too many defective cans produced during the can manufacturing process (in this case, inspection of the can manufacturing process is required)?
It is effective to determine if there is a problem with the can tester, or if there is some problem in the can testing machine that is causing excessive waste.

The can tester disclosed in the U.S. Pat. This can test data is used by the can tester to perform various υ control actions. The can test data signal indicates a leaky or unpainted can and activates the solenoid to dispose of the can to scrap. In order to modify the operation of the can tester, a fii control signal is generated which avoids activating the control circuitry of the can tester, which is described in more detail in Rogcr, December 14, 1982, entitled ``Photomultiplier Tube Assembly''.

It is disclosed in National Special Application No. 449764.

Since the scrap rate has important implications for the economic efficiency of the overall can vJ building process, it is useful to determine whether the defect occurred during the can testing process or during the can vJfI process. For example, pockets in can testers are caused by production of tJgA rows of tracks or defects. Similarly, unpainted can signals caused by defects in the can painting process or the need for adjustment of the unpainted can sensor
01 is discarded from the can tester. Therefore, it is most important to discover the nature of the cause of can waste. For example, if the flange seal of a particular pocket of a can testing machine is found to be defective, it is especially important to discover the nature of the cause of can waste. If it is reasonably determined that the same piece of hardware, such as a flange seal,
It is economically expedient to treat the flange seals in order to significantly reduce the proportion of scrap.

Additionally, it would be useful to quantitatively ascertain the proportion of scrap as a function of the total number of cans processed.

There is usually no quantitative measurement of the number of discarded cans. Although it is easy to see if there would be a very large change in the proportion of scrap as a result of the large number of discarded cans,
It is often very difficult to discern changes in the proportion of scrap that are not extremely large without quantitative measuring equipment. This is a result of the can testing machine operating at different i degrees, and these different speeds result in the scrap percentage varying depending on the production speed of the machine. Therefore,
If the proportion of scrap is strictly measured by the scrap stars placed in the scrap bin at a particular time, it is virtually impossible to determine. Moreover, the slow change in scrap rate does not show any appreciable increase in good periods. For example, a four-fold or five-fold increase in the rate of scrap over several months may not be noticeable to the employee emptying the disposal i.

Therefore, as well as detecting significant changes in the proportion of scrap, monitoring equipment is needed that provides information as to whether the problem is in the can manufacturing process or in the raw testing machine itself, as well as information on the nature of the particular problem. It is effective to provide

This is schematically shown in the software configuration diagram in FIG.
This includes a preferred embodiment for processing and analyzing data in accordance with the present invention by the CPU iO, optically isolated input/output interface 12, RΔM 14, and PROM 16 shown in FIG.

In operation, the rough one-ware configuration shown in FIG. 3 begins with an initialization task that serves to configure the microcomputer's hardware and specify how the hardware will perform the various tasks of the program. It will be done. The pulse pocket task 46 waits for a message from the RQ L4 exchange 49 indicating that the pulse pocket has been adjusted in the can tester. This vJ report is based on the hardware theory I! shown in Figure 1! I! From the circuit 26, it is fed through the optically isolated input/output interface 12. The 1IQL3 exchange 47 sends a 5-byte interrupt message when the turret of the can testing machine rotates once. The pulse rotation task 48 then sends a message to the zero exchange 50 to reset the pulse pocket task to zero. Since there are twelve can pockets 1- in the turret of the apparatus of the preferred embodiment of the present invention, the zero exchange metage indicates that the turret is between the can pockets 1-12. Pulse Pocket Task 46 is ZeI] Exchange 5
After receiving a reset signal from the zero exchange 50 from 0 h),
The pulse pocket task 46 receives another pulse pocket message in the RQL4 exchange 49.

For each set of can test data for which a can pocket number has been assigned by pulse pocket task 46, a blank message is retrieved from message boolean 52. This data indicates the pocket number and the status of the can in that pocket, whether it has been tapped, detected as a leaky can, unpainted can, or whether that pocket is empty. raw data exchange 51. The pro-his data task 34 retrieves data from the raw data exchange 51 and creates a data array of the three raw test data criteria found for each pocket. Can test data from Raw Data Exchange 51 to Pro 1? When transferred to data task 34, three criteria for each pocket are added for a predetermined period of time.

According to the invention, the predetermined period was set to 15 minutes.
Each time raw data exchange 51 places a message into a process data task, a null message is returned to message Boolean 52 for reuse.

Three can test data criteria are placed in the buffered data array of process data task 34 according to the assigned number of conversion pockets. This 3x12 array is accumulated for a given 15 minute period until a message is obtained from work exchange 54 indicating that the 15 minute period has elapsed.

When a message arrives from the work exchange 54, the process data task 34 picks up the blank message from the Boolean 2 exchange 56 and transfers the data array accumulated in the buffer of the process data task 34 to the format exchange 58.
Put it in. When the data array moves to format intersection 1*58, the process data task 34 buffer is removed.

The data array is then accepted by the data array and analysis task 36.38, which stores the data array and the rim-successive data array in the current data array. A summation and analysis task 36.38 then performs the various summation and analysis operations described above. For example, a total analysis task may include: total number of cans processed, total number of discarded cans, total number of leaking cans detected, total number of unpainted cans detected, and total number of empty cans detected during a given 15 minute period. The sum of the test data from the data array showing the total number of pockets

8 means that the total number of unpainted cans detected is 1 in a predetermined 15 minutes.
If it exceeds 0@, it will indicate a high percentage of unpainted cans, and if the total number of empty pockets detected exceeds 50, it will indicate a jam in the supply system, and if it is between 1 and 50. Indicates a high percentage of empty pockets indicating the need for adjustment of the oxidation sensor in the pocket, and detects leaking cans when the total number of leaking cans detected exceeds 0.55% of the total number of cans processed. A high rate indicates that the number of cans discarded from a particular pocket is more than three times the average number of cans discarded in other pockets in a given 15-minute period, and Indicates a defective pocket if the average number of cans exceeds twice the average number of cans processed, and indicates an excess scrap pocket if the percentage of the total number of discarded cans to the total number of cans processed exceeds 0.55%. Provides analysis of one can test data in a data array indicating percentages. In addition to providing the analysis described above, summation and analysis task 36.38 provides a format for writing the data summed and analyzed in summation and analysis task 36.38 to display device 24. In addition, the summation and analysis task 36.38 can be configured to automatically stop the can test 28 if any of the above percentages are indicated or as indicated by the dotted line in FIG. To operate the control circuit 27,
It is also easily possible to program the control signal 25 to generate when some predetermined percentage is indicated. It is also possible to perform manual operations according to predetermined criteria that regulate the operation of the machine.

Real time: 164 waits for one minute in the time exchange 65, and if the message does not arrive, the real time clock 6
4 updates the time by 1 minute. Further, the real time clock 64 checks whether a predetermined time has elapsed. If time has elapsed, real time clock task 64 sends a message to work exchange 54 indicating that 15 minutes have elapsed.
