FIG. 8 will be described.

FIG. 8 is a cross-sectional view of the tablet hopper 24 of the tablet supply device, which is arranged directly below the unpacking position where the tablet unpacking operation is performed. A beam sensor for detecting tablets and aluminum pieces is installed in the hopper, and is detected using the input of the beam sensor.
Reference numeral 24 denotes a tablet hopper that sends tablets and aluminum pieces, which are fallen objects, to the packaging machine main body, and is arranged directly below the unpacking position of the tablet take-out unit.

  Reference numeral 50 denotes a fallen object (tablet or aluminum piece) that passes through the tablet hopper, and represents an unwrapped tablet or an aluminum piece that has been accidentally dropped. The fallen object passes through the beam sensor from the top of the tablet hopper and is sent to the packaging machine body.

  A beam sensor 204 detects a fallen object. When the unwrapped tablet falls in the tablet hopper, it passes over the beam sensor and shields the beam sensor. The state where the beam sensor is shielded from light is referred to as an ON state, and the state where the beam sensor is not shielded is referred to as an OFF state. Using this ON / OFF state, a fallen object is determined.

The operation state of the tablet supply device (except for the error state) is roughly classified into the state during the unpacking process and the other state. The aluminum piece detection process is divided into processes other than during the unpacking process and during the unpacking process, and will be described with reference to the flowcharts of FIGS. 9, 10, and 11.
FIG. 9 will be described.

FIG. 9 shows a flowchart for detecting an aluminum piece in a state where no depackaging processing is performed. Since the unpacking operation is not performed, it is determined that the falling item is an aluminum piece or a pill with a mistake that could not be taken out by the previous (one previous) unpacking operation, and error information is sent to the medicine packaging machine. In the medicine packaging machine body, error printing is performed using the printer 706 of FIG.
In step S <b> 1001, the tablet supply device acquires the state of the beam sensor 204.
In step S1002, the tablet supply device determines whether or not the state of the beam sensor has been switched to the ON state, and detects the fall of the tablet or aluminum piece.
In step S1003, the tablet supply device acquires the state of the beam sensor 204.

In step S1004, the tablet supply device determines whether or not the state of the beam sensor has been switched to the OFF state, and waits for a dropped take-out tablet or aluminum piece (foreign matter) to pass through the tablet hopper.
In step S1005, it is determined that the tablet supply device is not an aluminum piece or a tablet dropped during the unpacking operation, and is defined as a tablet erroneous drop error or an excessive tablet error.

  When an erroneous tablet drop error or excessive tablet error occurs, the error contents are inserted in the order of 402 and 501 to 505 in FIG. 6 so that the printer 706 can recognize at a glance that the paper is a wrapping paper in which the erroneous drop error has occurred. To print.

  Further, the first relay unit 502 (first delivery mechanism) is operated when an operation request from the medicine packaging machine (packaging device) body is made to the tablet supply device, and is put into the packaging paper subjected to error printing. The timing of packaging by the packaging mechanism is adjusted (controlled) so that it can be done.

Similarly, the 504 second relay unit (second delivery mechanism) is also operated when an error request is issued from the medicine packaging machine (packaging device) main body to the tablet supply device, and the wrapping paper is printed with error. The timing of packaging by the packaging mechanism is adjusted (controlled) so that it can be put into the package.
10 and 11 will be described.

  10 and 11 are flowcharts for detecting a tablet or aluminum piece (foreign matter) that has been taken out in a state where the packaging process is being performed. Based on the number of times the input / output of the beam sensor has been switched ON / OFF, it is determined that the tablet has been successfully taken out, the tablet has been taken out incorrectly, and the aluminum piece has been mixed. When the ON / OFF switching is performed once, it is determined that only the tablet has been correctly taken out, and the removal is successful. If there are more than two times, it is judged that aluminum pieces have been mixed in, the tablets have been damaged, and more than the specified number have been taken out. Is sent and error printing is performed on the wrapping paper.

  When an aluminum piece or the like is detected during the unpacking operation, all the tablets being unpacked are stored in the second stacking hopper, and after confirming that the tablet take-out device has stopped, the second relay unit (second delivery mechanism) To the second integrated hopper. Thereafter, the unpacking operation is performed as usual in the tablet takeout device.

  In step S1101, it is determined whether the tablet supply device has transported the tablet sheet to the unpacking position 300. If the tablet sheet has already reached the unpacking position, the process proceeds to step S1109, and if not, the process proceeds to step S1102.

That is, here, it is determined whether or not the pushing mechanism is in a pressing operation. If it is determined by the determination means that the pressing operation is being performed, the flow proceeds to S1109. If it is determined by the determination means that the pressing operation is not being performed, the flow proceeds to S1102.
In step S1102, the tablet supply device conveys the tablet sheet to the unpacking position 300.
In step S1103, the tablet supply device acquires the state of the beam sensor during tablet sheet conveyance.

In step S1104, the tablet supply device checks whether or not the tablet has fallen during conveyance from the state of the beam sensor acquired in step S1104. If it is determined that it has been switched to the ON state, it is determined that it has been dropped, and the process proceeds to step S1105. In the OFF state, the process proceeds to S1108.
In step S1105, processing similar to that in step S1103 is performed.

  If it is determined in step S1106 that the beam sensor state acquired in step S1105 has been switched to the OFF state, the tablet supply device regards that the tablet has passed through the tablet hopper while the tablet sheet is being conveyed, and the process proceeds to step S1107. If it is in the ON state, it is determined that it is passing through the tablet hopper, and the process proceeds to step S1105.

That is, here, when the detection mechanism counts the number of tablets taken out exceeding the predetermined number, the process proceeds to S1107. When the detection mechanism counts the number of extracted tablets that does not exceed the predetermined number, the process proceeds to S1105.
Here, the predetermined number is set to zero.
In other words, here, the detection mechanism counts the number of tablets taken out from the tablet container, thereby detecting a take-out error not depending on the pressing operation.

  In step S1107, error processing is performed when there is an extraction error not due to the pressing operation because the beam sensor has been turned ON / OFF more than once when the unpacking operation is not performed (when the pressing operation is not being performed). This error state is defined as a tablet erroneous fall error.

This is an erroneous tablet drop error process that occurs while the PTP sheet is being conveyed to the unpacking position. In the same manner as after the stop of the PTP sheet conveying operation of the tablet supply device and the occurrence of the erroneous drop error described in step S1005 in FIG. Is put on the printed wrapping paper.
That is, here, the packaging apparatus 5 is requested to execute error processing.

In step S1108, it is checked whether the tablet supply device has finished transporting the tablets. If completed, the process proceeds to step S1109 in order to perform the depackaging process. If not completed, the process proceeds to step S1102.
In step S1109, after reaching the unpacking position, the tablet supply device performs the unpacking operation (pressing operation).
In step S1110, the tablet supply device checks the end of the unpacking process (pressing operation).

  In step S1111, the number of dropped tablets is checked to check whether the unpacking operation is successful. When the number of dropped tablets = “1”, it is determined that the unpacking has succeeded (there is no error processing since the unpacking has been completed normally), and the process proceeds to step S1112. In other cases, it is determined that unpacking has failed or aluminum pieces are mixed, and the process proceeds to step S1113. Counting the number of falling tablets is performed in steps S1115 to S1119.

  That is, here, when the detection mechanism counts the number of tablets taken out that coincide with the predetermined number, the process proceeds to S1112. When the detection mechanism counts the number of extracted tablets that do not match the predetermined number, the process proceeds to S1103.

  In step S1112, the tablet supply device checks whether the number of tablets designated from the main body of the packaging machine has been successfully unpacked at the start of unpacking. When the specified number of tablets have been unpackaged, the operation ends. If the unpacking is not completed, the process proceeds to step S1101 in order to pack the tablet.

  In step S1113, the tablet supply device checks the mixing of aluminum pieces. When the number of dropped tablets> “1”, it is considered that not only tablets but also aluminum pieces are mixed in the wrapping paper, and the process proceeds to step S1114. In other cases, it is regarded as unpacking failure and the process proceeds to step S1101 to perform the unpacking operation again.

That is, here, when the detection mechanism counts the number of tablets taken out exceeding the predetermined number, the process proceeds to S1114. When the detection mechanism counts the number of extracted tablets that does not exceed the predetermined number, the process proceeds to S1101.
Here, the predetermined number is set to at least one.
That is, in this case, the detection mechanism counts the number of tablets taken out from the tablet container, thereby detecting the contamination of the foreign matter due to the pressing operation.

  In step S1114, error processing is performed when aluminum pieces (foreign matter) are mixed because the beam sensor has been turned ON / OFF more than twice during the unpacking operation (pressing operation). Is defined as an excessive tablet error.

When an excessive tablet error occurs, the unpacking operation of the tablet supply device is terminated, and error information (information for notifying that foreign matter is mixed by the pressing operation) is transmitted to the packaging machine body. Then, in the same manner as after the erroneous fall error described in step S1005, the aluminum piece is transported and put into the wrapping paper on which the error information is printed.
That is, here, the packaging apparatus 5 is requested to execute error processing.
In step S1115, the tablet supply device acquires the state of the beam sensor being unpacked.

In step S1116, the falling of the tablet is detected from the beam sensor state acquired in step S1115. If it is determined that the state has been switched to the ON state, it is considered that the object has fallen, and the process proceeds to step S1117. If it is OFF, the process proceeds to S1110.
In step S1117, the number of times the beam sensor transitions to the ON state (the number of times of switching) is counted, and the total number of falling objects during the pressing operation is counted.
In step S1118, the same processing as in S1115 is performed.

In step S1119, it is checked from the beam sensor state acquired in step S1118 whether a fallen object is passing through the hopper. If it is determined that the state has been switched to the OFF state, it is considered that the object has passed through the tablet hopper, and the process proceeds to step S1110. In the ON state, it is considered that the object is passing through the tablet hopper, and the process proceeds to step S1118.
