The extruding mechanism presses the tablet housing portion with the outer pressing body before the inner pressing body.

  Reference numeral 83 denotes an inner pressing body. Since the tip of the inner pressing body has a smaller area than the tablet accommodating portion of most tablet sheets, the tip of the inner pressing body protrudes from a hole opened in the tablet sheet when taking out the tablet (when descending).

Reference numeral 84 denotes an outer pressing body. Since the tip of the outer pressing body has a larger area than the tablet accommodating portion of most tablet sheets, the tip does not protrude from the hole opened in the tablet sheet when the tablet is taken out (lowered). That is, it is for crushing the tablet accommodating part of a tablet sheet.
The tablet taking-out mechanism (extrusion mechanism) has a first lifting mechanism that lifts and lowers the outer pressing body and a second lifting mechanism that lifts and lowers the inner pressing body.

  The first elevating mechanism includes a first elevating body to which an outer pressing body is attached, a cam that is rotationally driven to raise and lower the first elevating body, and an urging member (spring) that urges the first elevating body in the upward direction. And.

FIG. 5 will be described.
FIG. 5 is a diagram showing an internal structure of the tablet supply device.
It is the figure which looked at the tablet supply apparatus from the back side.

An optical sensor (beam sensor) 204 detects a fallen object. When the unwrapped tablet falls in the discharge hopper (introduction chute), the unwrapped tablet 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 tablet falling detection mechanism includes an optical sensor and a falling tablet counter.
The tablet supply device has a detection mechanism 204 that detects the extracted tablet in order to determine whether or not the tablet has been extracted from the tablet container by pressing.

FIG. 8 will be described.

  FIG. 8 is a diagram in which the block (outer pressing body) is operated after reaching the unpacking position during normal unpacking, and the aluminum foil of the PTP sheet is broken. The block is intended to break the aluminum foil and at this point the tablet cannot be removed.

  When the tablet sheet 51 reaches the mounting table and the tablet accommodating portion from which the tablets are to be taken out reaches a position corresponding to the discharge port, the cam of the first elevating mechanism is rotated by the rotation of the shaft portion, and the first elevating body is moved. By lowering, the outer pressing body is lowered, and the lower edge portion presses the portion outside the central portion of the tablet housing portion downward.

Since the outer pressing body presses a portion outside the central portion of the tablet accommodating portion, a direct force is not applied to the tablet as compared with the case where the central portion is pressed. For this reason, the tablet is not completely taken out, but a part of the tablet breaks the sealing sheet and comes out of the tablet container. In this state, since the tearing of the sealing sheet is slight, the tablet is supported by the sealing sheet, and a part of the tablet remains in the tablet accommodating portion. Further, the encapsulating sheet is not largely broken and no debris is generated.
FIG. 9 will be described.

  In FIG. 9, at the time of normal unpacking, the extrusion plate is operated to extrude the tablet so as to protrude. Even if a series of operations are performed, the tablet may be sandwiched between the aluminum foils of the PTP sheet, and the tablet may not be taken out.

  Next, the cam of the second elevating mechanism is rotated by the rotational drive of the shaft portion, and the inner pressing body is lowered by lowering the second elevating body, and the extending end portion lowers the central portion of the tablet accommodating portion. Press.

  Since the inner pressing body presses the central portion of the tablet accommodating portion, a direct force is applied to the tablet, and the tablet is completely removed. As a result, tearing of the sealing sheet is enlarged, but this tearing is caused by the tearing of a few minor points in the initial stage caused by the outer pressing body being widened by the inner pressing body, so there are few breakage points and sealing Sheet separation is unlikely to occur.

  On the other hand, when a large force is applied to the tablet accommodating portion at one time and the sealing sheet is torn, it is easy for tearing to occur at many locations on the sealing sheet at the same time, so that fragment separation is likely to occur.

Thus, since the tablet is partially removed from the tablet container by the first stage pressing by the outer pressing body, and then the tablet is completely removed from the tablet container by the second stage pressing by the inner pressing body, The pressing force applied to the tablet at each stage is small. For this reason, compared with the case where a big force is applied to a tablet accommodating part at once, a tablet is hard to break.
FIG. 10 will be described.
FIG. 10 is an enlarged view of FIG.
The tablet taking-out mechanism has a pressing portion and an elevating mechanism that moves the pressing portion in a direction approaching the tablet accommodating portion.

The pressing unit includes an inner pressing body (extruding plate) that presses the central portion of the tablet housing portion and an outer pressing body (extruding block) that presses a portion outside the central portion of the tablet housing portion.
The outer pressing body further includes a front wall portion, a rear wall portion provided in parallel with the front wall portion with a rearward interval from the front wall portion, and an inner wall portion provided at an inner edge of the front wall portion and the rear wall portion. And have.
In other words, the outer pressing body has a front and rear wall portion which is a pair of facing wall portions facing each other, and an inner wall portion provided between one edge portion of these.

  Since the lower edge part of the outer pressing body is shaped so that the lower edge part of the front wall part and the rear wall part extend in the width direction from the front and rear ends of the lower edge part of the inner wall part, when the outer pressing body descends, Lower edges of the front and rear wall portions and the inner wall portion press the tablet housing portion.

The inner pressing body is a plate-like body having an extended end portion whose width becomes narrower toward the lower end, and is inserted into a space surrounded by the front wall portion, the rear wall portion, and the inner wall portion of the outer pressing body. Can move up and down within.
FIG. 11 will be described.

FIG. 11 shows a diagram of the vibration operation during retry (continuation) unpacking. If the aluminum foil is broken by a series of operations and the tablet cannot be removed even if the tablet is pushed out by the extrusion plate, the unpacking operation in FIG. 15 is changed at high speed (changing mechanism), and the PTP sheet is vibrated. give. By giving vibration, the vibration is transmitted to the tablet sandwiched between the aluminum foils, and the sandwiched state can be released.
FIG. 12 will be described.
FIG. 12 shows a flowchart of the unpacking operation and vibration operation during retry unpacking. The operation procedure is as follows.
During the unpacking operation, the input of the drop sensor 204 is constantly monitored, and if there is a change in the input, the drop counter value is updated. However, the value at the start of the unpacking operation is “0”.
In step S101, the rotation direction and rotation amount of the unpacking motor 2901 are set so that the extrusion unit descends to the PTP sheet.
In step S102, the unpacking motor 2901 is operated.
In step S103, the operating state of the unpacking motor 2901 is acquired.

  In step S104, it is checked whether the unpacking motor 2901 is stopped from the state of the unpacking motor 2901 acquired in S103, and the process of S103 is executed until the operation stops.

In step S105, during S101 to S104, if the number of times the drop sensor 204 is input in the tablet hopper is “1” or more, the process proceeds to S106, and otherwise, the process proceeds to S111.
In step S106, the rotation direction of the unpacking motor 2901 is set so that the extrusion unit moves up to the initial position.

In step S107, the unpacking motor 2901 is operated until the initial position sensor 280 that is the standby position of the extrusion unit is turned ON for the extrusion plate (inner pressing body) and the extrusion block (outer pressing body).
In step S108, the state of the initial position sensor 2801 is acquired.

In step S109, the state of the initial position sensor 2801 acquired in S108 is checked. If the initial position sensor 2801 is ON, the process proceeds to S110, and if it is OFF, the process proceeds to S108.
In step S110, the unpacking motor 2901 is stopped and the unpacking operation is terminated.

In step S111, the number of vibrations is checked. If the number is less than the set number of vibrations, the process proceeds to S112. Otherwise, the process proceeds to S106 in order to move the extrusion unit to the initial position.

In step S112, the rotation direction and rotation amount of the unpacking motor 2901 are set so that the extrusion unit descends. The rotation amount at this time is different from the rotation amount of S101 because of the vibration operation.
In step S113, the unpacking motor 2901 is operated until the extrusion unit moves to the set position.
In step S114, the same process as S103 is performed.

  In step S115, it is checked whether the unpacking motor is stopped from the state of the unpacking motor 2901 acquired in S114, and the process of S114 is continued until the operation is stopped.

  In step S116, similarly to S105, the number of inputs of the drop sensor 204 is set in the drop counter between S111 and S116. If “1” or more, the process proceeds to S106, and otherwise, the process proceeds to S117. .

In step S117, the rotation direction of the unpacking motor 2901 and processing are performed so that the extrusion unit moves up. Similar to S115, the set value differs from S106 because of the vibration operation.
In step S118, the unpacking motor 2901 is operated until the extrusion unit moves to the set position.
In step S119, the same process as S103 is performed.

  In step S120, it is checked whether the unpacking motor 2901 is stopped from the state of the unpacking motor acquired in S119, and the process of S119 is executed until the operation stops.

In step S121, as in step S105, the drop counter value is checked during execution of steps S105 to S116. If “1” or more, the process proceeds to step S106. Otherwise, the process proceeds to step S122.
In step S122, the vibration counter value is incremented by one.
FIG. 13 will be described.
FIG. 13 shows the movement of the tablet sheet at the unpacking position (position for taking out the tablet from the tablet container) during retry unpacking.

  If unpacking is still not possible after the vibration operation, the unpacking position is moved in the front-rear direction. By moving the unpacking position, the position where the tablet is pushed out changes, so that it is possible to take out the tablet that was sandwiched between aluminum foils and could not be taken out. However, if the unpacking is successful, the unpacking position is moved to the center of the PTP sheet pocket.

In 601 to 603, since the extrusion unit has pushed the tablet, the extrusion unit is caught by the PTP sheet as it is, and the tablet cannot be conveyed. Therefore, the extruding plate and the block of the extruding unit are arranged at the initial position so as not to contact the PTP sheet, and the unpacking position is moved.
Reference numeral 601 denotes a case where the tablet does not fall after the same operation as that in FIG.

  Reference numeral 601 denotes a state where the PTP sheet reaches the unpacking position and the tablet is taken out from the PTP sheet. When the tablet can be taken out by this operation, only the operation 601 is performed, and the operation proceeds to the operation of taking out the next tablet. If it cannot be removed by this operation (such as being sandwiched between aluminum foils), the operation proceeds to 602.

Reference numeral 602 denotes a state where the upper end of the pocket of the PTP sheet is being pressed. When the tablet cannot be taken out from the PTP sheet in 601, it is difficult to take out the tablet if it is sandwiched between aluminum foils or the like even if the same place is pushed again. In this case, by changing the extrusion position, it is possible to reduce resistance due to the pinching of the aluminum foil or the like, and it is possible to take out the tablet from the PTP sheet (tablet sheet).
If it cannot be taken out by this operation, the operation proceeds to operation 603.

Reference numeral 603 denotes a state where the lower end of the pocket of the PTP sheet is being pressed. If the tablet cannot be taken out from the PTP sheet even at 602, the resistance due to the pinching of the aluminum foil or the like can be reduced by changing the position to be pushed out again. Tablets can be pushed out by reducing this resistance.
Reference numeral 601 denotes a position where the first unpacking is performed after reaching the unpacking position.
Reference numeral 602 denotes a depackaging position where retry (re) unpacking of the odd-numbered unpacking operation is performed.
Reference numeral 603 denotes an unwrapping position at which retry (re) unpacking of the even number of unpacking operations is performed.
FIG. 14 will be described.

  FIG. 14 shows a flowchart when the tablet take-out unit 1 moves the tablet sheet to the unpacking position (position for taking out the tablet from the tablet container) during retry unpacking, and changes the push-out position.

In the first movement process of the unpacking position, the value of the transport counter is set so as to unpack the front side of the PTP sheet pocket from the center of the PTP sheet pocket (tablet accommodating portion). From the second time onward, a value that moves to the front / back side of the PTP sheet pocket is set in the conveyance counter. (* The value to be set here is the process of measuring the pocket size of the PTP sheet when transported to the unpacking position, and the measurement result is used.)
The front / back side of the PTP sheet pocket is determined based on the value of the retry counter, and when the unpacking is successful or the upper limit of the number of movements is exceeded, the value is set to “0”.

The number of retries described here represents the number of unpacking failures of the tablet that is currently performing the unpacking operation. During this movement, the extruding unit touches the tablet and does not hinder the transport of the tablet.

In step S201, the number of retries is checked, and if it is an odd number, the process proceeds to S202 in order to unpack the back side portion of the tablet sheet in the traveling direction (state 602 in FIG. 13). If it is an even number, the process proceeds to S210 in order to unpack the front side portion of the tablet sheet in the traveling direction (state 603 in FIG. 13).
In step S202, the distance for moving the tablet on the PTP sheet is set in the retry conveyance counter.
In step S203, the rotation direction of the transport motor is set so that the tablet sheet moves backward.
In step S204, the transport motor is operated to retract the tablet sheet. (State 602 in FIG. 13)
In step S205, the retry conveyance distance is decremented and the remaining conveyance distance is updated.
In step S206, the retry conveyance distance is checked, and if the designated distance movement is completed, the process proceeds to S207, and if not, the process proceeds to S204.
In step S207, the transport motor is stopped.
In step S208, the rotation direction of the transport motor is set to be the normal forward direction.
In step S209, the number of retries is incremented.
In step S210, the same process as S202 is performed.
In step S211, the conveyance motor is operated to advance the tablet sheet. (State 603 in FIG. 13)
In step S212, the same processing as in S205 is performed.
In step S213, the retry conveyance distance is checked, and if the designated distance movement is completed, the process proceeds to S214, and if not, the process proceeds to S211.
FIG. 15 will be described.
FIG. 15 is a flowchart showing the state of the unpacking operation during normal unpacking.
In step S501, it is checked whether the tablet has reached the unpacking position.
In step S502, the extrusion block 84 is operated.

In step S503, the aluminum foil is shattered using the force that pushes out the tablet by operating the extrusion block. Extruded blocks do not have the function of extruding tablets and exist only to break aluminum foil. If the aluminum foil is not torn before extruding the tablet, peeling of the aluminum foil and cracking or chipping of the tablet will remarkably appear. When trying to extrude a tablet from the PTP sheet in one operation, the aluminum foil on the back of the PTP sheet becomes resistance, and the operation of breaking the aluminum foil and the operation of extruding the tablet must be performed at the same time. Therefore, the above problems occur.
In step S504, the extrusion plate 83 is operated.

In step S505, the extrusion plate is operated to take out the tablet. Since the aluminum foil is broken in S503, the resistance to the tablet is reduced. Thereby, the cracking and chipping of the tablet can be prevented.
In step S506, the tablet sheet is conveyed to the unpacking position.
FIG. 16 is a view showing a position for detecting the tablet container and a position for unpacking the PTP sheet.

112 is arranged on the side surface through which 103 passes and the unevenness of the seat pocket is detected. By detecting this unevenness, the width dimension of the pocket can be determined. Based on the calculated value, the center position of the seat pocket is moved to 114.
Reference numeral 51 denotes a PTP sheet.
Reference numeral 17 denotes an optical sensor, which is used for measuring the length of the tablet container.
301 represents the detection position of the tablet (tablet storage part) by the optical sensor 17, and the length of the tablet storage part is measured when the tablet storage part passes (blocks).
Reference numeral 300 denotes an unpacking position (tablet taking-out position), which is a position for performing the unpacking operation for taking out the tablet.
FIG. 17 will be described.
FIG. 17 shows a flowchart for measuring the length of the tablet container using the optical sensor 17.

Here, the conveyance (movement) distance of the tablet sheet during normal unpacking and the conveyance (movement) distance of the tablet sheet during retry unpacking in steps S202 and S210 are calculated.
In step S301, the transport motor is advanced to transport the tablet sheet forward.
In step S302, the state of the optical sensor 17 is acquired.

In step S303, it is determined from the acquired state of the optical sensor whether it is ON (the tablet container is shut off). If it is ON, the process proceeds to step S304. If it is not ON, the process proceeds to step S301.
In step S304, the position of the tablet container is detected. Start measuring the length of the tablet container.
In step S305, the transport motor is advanced to transport the tablet sheet forward.
In step S306, the state of the optical sensor 17 is acquired.

  In step S307, it is determined from the acquired state of the optical sensor whether it is OFF (the tablet container is not shut off). If it is OFF, the process proceeds to step S308. If not OFF, the process proceeds to step S304.

In step S308, the measurement of the length of the tablet container is finished. Based on the position of the tablet container measured here, the conveyance (movement) distance of the tablet sheet from the detection position to the unpacking position is calculated.
Furthermore, based on the length of the tablet storage unit measured here, the transport distance (predetermined distance) of the tablet sheet at the time of retry (during continuation) is also calculated.
The travel distance of the tablet sheet at the time of retrying is calculated based on the result of the length of the tablet container so that the distal ends on the far side and the near side in the traveling direction are the unpacking positions.
The retry conveyance distance is the difference between the measured radius of the tablet sheet and the radius of the tip of the push plate. The tablet sheet is moved by a predetermined distance forward and backward by the distance of the tablet sheet transport (movement) calculated during the retry, calculated based on the center of the tablet container.
FIG. 18 will be described.
When the PTP sheet passes through the interval sensor sensing unit 17, the size of the sheet pocket is measured by the sensor 17, and the PTP sheet is conveyed to the tablet removal position. FIG. 18 is a diagram showing a PTP sheet passage path of the interval sensor sensing unit 17 in the embodiment of the present invention.

By providing a fine groove 1002 (about 0.6 mm) in the passage path of the PTP sheet, it is pushed from the vertical direction and warpage is prevented during passage. Further, by providing the minute groove portion in the distance sensor sensing portion, the dimension of the sheet pocket can be measured in a state where the warp of the PTP sheet is prevented.
FIG. 19 will be described.
FIG. 19 shows the order of the tablet pockets 52 in which the tablet take-out unit 1 performs the unpacking operation for each pack from the tablet sheet 51.

  Reference numeral 2701 denotes an arrow indicating the order of the unpacking operation. For example, when there is a request for taking out a total of 3 tablets, the take-out operation is sequentially performed from the back side in the sheet traveling direction. Unpacking operation on the left row side (1st tablet) → Unpacking operation on the right row side (2nd tablet) → Transport of tablet sheets to the next row → Unpacking operation on the left row side (3rd tablet) Take out the tablets.

In the unlikely event that the take-out operation fails in the middle, the take-out operation on the left side → the take-out operation on the right side → the transport to the next row → the eject operation on the left side → the eject operation on the right side → the transport to the next row → This operation is repeated until the predetermined number of three tablets are successfully taken out, that is, until the tablet sensor 204 detects a total of three tablets.
FIG. 20 will be described.
FIG. 20 shows the internal structure of the unpacking motor mechanism of the tablet taking-out unit 1.

Reference numeral 1111 denotes a shaft. Two cams 94, two cams 99, and a shielding plate 2802 are fixed to the shaft at a preset angle with respect to the rotation axis of the shaft.
When the rotating shaft is rotated by driving by the depacking motor, the two cams 94, the two cams 99, and the shielding plate 2802 fixed to the shaft are also rotated in conjunction with each other.

  Also, in order to share the initial position during left-row unpacking and right-row unpacking, the two cams 94 fixed at a preset angle are unwrapped at the midpoint of the angle formed with respect to the rotation axis. The initial position of operation is set. In other words, the left row cam is at an angle (for example, 45 °) that is equal to the reference angle (for example, 0 °) of the unpacking motor, which is the initial position of the unpacking operation, and the direction in which the unpacking motor 2901 rotates is exactly opposite. 94 and the right row cam 94 are fixed. Similarly, the left row cam 99 and the right row cam 99 are located at the same angle (eg, 135 °) from the reference angle (eg, 0 °) of the unpacking motor and in the opposite direction of rotation of the unpacking motor. Each is fixed.

  Reference numeral 2801 denotes an initial position sensor. This sensor is an optical sensor and detects ON / OFF depending on whether or not an object blocks light. When the input of the initial position sensor is ON, it is determined that the cam has reached the initial position.

  Only one initial position sensor is arranged for the tablet take-out unit 1 so that the initial position 350 at the time of unpacking the left row and the initial position 380 at the time of unpacking the right row are common. This is because the angle used as the reference for the unpacking motor is common when unpacking the left row and unpacking the right row.

  Since one initial position sensor 2801 can be used in common, the tablet can be removed by simply starting rotation in different directions (forward or backward) at the time of left row unpacking and right row unpacking starting from this reference angle. It is possible to take out left and right one by one, and it is not necessary to manage the initial position separately for left row unpacking and right row unpacking, and it is possible to easily control the unpacking operation. Play. Furthermore, since the mechanism of the expensive unpacking motor 2901 can be shared by using one initial position sensor 2801 in common, the manufacturing cost of the tablet dispensing unit 1 can be reduced.

  2802 is a light shielding plate for turning on / off the initial position sensor, and is fixed to the tip of the shaft 1111. When the light shielding plate blocks the light of the initial position sensor, the light is turned on (the shaft rotation angle is at the reference angle).

Reference numeral 2901 denotes a depacking motor. By rotating the unpacking motor, the shaft 1111 rotates in conjunction with each other, and the rotation angle of the block cam and the push-out plate cam fixed to the shaft 1111 can be controlled.
Reference numeral 2902 denotes a depacking motor pulley.

Reference numeral 2903 denotes a shaft pulley, which is connected to a depacking motor pulley by a belt. The shaft pulley and the rotating shaft (shaft) of the cam are also connected, and the rotation of the unpacking motor pulley, the rotation of the shaft pulley, and the rotation of the cam are all controlled by the rotation of the unpacking motor 2901.
FIG. 21 will be described.
When performing the unpacking operation in the left column (normal time), the unpacking operation is performed in the order of 350 → 360 → 370 → 360 → 350 as shown in FIG.
Reference numeral 350 denotes an initial position of the cam 94 when the left-side unpacking operation is performed.

  Reference numeral 360 denotes the lowest point of the block 84 in the left column. The shaft 1111 rotates backward from the state of 350, and the cam 94 presses the first elevating body 93. 84 shows a state where the lowest point is reached. As the unpacking motor 2901 rotates, the cam 94 rotates, and the block 84 descends before the pushing plate 83. The block 84 breaks the aluminum foil in the pocket until the block 84 starts to descend and reaches the lowest point of the block 84.

  Reference numeral 370 denotes the lowermost point of the extrusion plate 83 in the left row. The shaft 1111 rotates backward from the state of 360, and the cam 99 presses the second elevating body 98, whereby the extrusion plate 83 descends. The state where the extruded plate 83 has reached the lowest point is shown. The push-out plate 83 pushes the pocket 52 to take out the tablet.

360 is the lowest point of the block 84, and the shaft 1111 is reversed in the forward direction from the state of 370, and the cam 94 presses the first elevating body 93, so that the block 84 is lowered and the block 84 is at the lowest position. The state where the lower point has been reached is shown.
Reference numeral 350 denotes the end position of the cam 94 when performing the left-side unpacking operation.

Here, when the initial position sensor 2801 is turned ON, it is determined that the state has returned to the state 350 (initial position) and the rotation of the unpacking motor 2901 is stopped, so that the push-out plate cam 99 and the block cam 94 are rotated. Stop.
FIG. 22 will be described.
When performing the unpacking operation (normal time) in the right column, the unpacking operation is performed in the order of 380 → 390 → 400 → 390 → 380 as shown in FIG.
Reference numeral 380 denotes an initial position of the cam 94 when performing the right row unpacking operation.

  390 is the lowest point of the block 84 in the right row, and the shaft 1111 rotates forward from the state of 380, and the cam 94 presses the first elevating body 93, so that the block 84 descends, 84 shows a state where the lowest point is reached.

  Reference numeral 400 denotes the lowest point of the extrusion plate 83 in the right row, and the shaft 1111 rotates forward from the state of 390, and the cam 99 presses the second elevating body 98, whereby the extrusion plate 83 descends. The state where the extruded plate 83 has reached the lowest point is shown.

390 is the lowest point of the block 84. The shaft 1111 is reversed backward from the state of 400, and the cam 94 presses the first elevating body 93, so that the block 84 is lowered and the block 84 is at the lowest. The state where the lower point has been reached is shown.
Reference numeral 380 denotes the end position of the cam 94 when performing the right-side unpacking operation.

Here, when the initial position sensor 2801 is turned ON, it is determined that the state has returned to the state 380 (initial position), and the rotation of the unpacking motor 2901 is stopped, so that the push-out plate cam 99 and the block cam 94 are rotated. Stop.
FIG. 23 will be described.

  When performing the unpacking operation (at the time of retry) in the left column, if the vibration is set to 3 times as shown in FIG. 23, 350 → 360 → 370 → 360 → 370 → 360 → 370 → 360 It operates in the order of → 370 → 360 → 350, and the vibrations in the block and the extrusion plate are repeated a set number of times.

  Similarly, when performing the unpacking operation (at the time of retry) in the right column, if the vibration is set to 3 times, 380 → 390 → 400 → 390 → 400 → 390 → 400 → 390 → 400 → 390 → Operates in the order of 380, and repeats the vibration of the block and the extrusion plate a set number of times.

In this way, 360 → 370 is repeated a set number of times (for example, 3 times) during the unpacking operation at the time of retry in the left column, but the cam is rotated at a higher angle at a shorter angle than the unpacking operation at the normal time. At this time, since the block and the pushing plate are alternately pressed at a high speed, vibration is applied to the PTP sheet 51, and it is possible to promote the dropping of the tablet caught on the aluminum foil. This operation is a vibration operation.
