Reference numeral 1701 denotes an aluminum foil on the back surface of the tablet sheet.

In the tablet take-out unit, the tablet housing part of the tablet sheet is pressed with a pressing body to try to take out the tablet. In some cases, tablets stick to the foil (adsorb) and do not fall. Or, even if it falls, there may be cases where it does not fall at the intended timing, for example, it falls after sticking to an aluminum foil. The intended timing refers to a predetermined time period during which free fall on the introduction chute is performed for correct packaging.
FIG. 13 will be described.
FIG. 13 is a cross-sectional view of a tablet sheet, which is another example in which the aluminum foil on the back surface of the tablet sheet is broken.

  This is an example in which the tablet taking-out unit presses the tablet containing portion of the tablet sheet with a pressing body to take out the tablet, but the tablet does not stick (adsorb) and fall on the inner surface of the tablet containing portion deformed by the pressing. Even in this case, even if it falls, there is a case where it does not fall at the intended timing, for example, it falls after sticking to the inner surface of the tablet container for a moment.

In the tablet taking-out unit, the tablet containing portion of the tablet sheet is pressed by the pressing body to take out the tablet. And since the tablet is introduced into the introduction chute by free fall and sent to the packaging machine, as described above, when the tablet is not sent out from the tablet take-out unit to the packaging machine in a timely manner, it cannot be correctly packaged as prescribed.

FIG. 15 will be described.
FIG. 15 is a simplified cross-sectional view from the right side of the tablet unit so that the inside of the tablet take-out unit can be seen.

When the tablet sheet is conveyed, the electrostatic charge on the back surface of the tablet sheet is first neutralized with the fed ions before the pressing body for taking out the tablet operates. At this time, the back surface of the sheet should not be neutralized at the same time, but ions pass from the back surface of the sheet to the surface after a slight time lag. As a result, the surface charge is also neutralized.
FIG. 16 will be described.
FIG. 16 is a simplified cross-sectional view showing a state where the tablet is taken out from the tablet sheet.

In the tablet taking-out unit, after the back and front surfaces of the tablet sheet are neutralized, the tablets in the tablet sheet are pressed by the pressing body and taken out. In this process, the aluminum foil on the back surface of the tablet sheet is broken, and at the same time, ions are fed into the inside of the tablet container from the hole where the aluminum foil is broken. And the inside of a tablet sheet tablet accommodating part and the charge of a tablet are neutralized.

As a result, the tablet taken out from the tablet sheet and the aluminum foil torn on the back side of the tablet sheet are not charged with static electricity. It falls to.
In order to take out the next tablet when the tablet falls, the tablet sheet is conveyed while continuing the ion irradiation, and the tablet is taken out again. Repeat this process.

The ions may be always emitted and released when the power of the tablet supply device and the medicine packaging machine is turned on, and after the sheet is set in the tablet supply device, the tablet sheet is transported and the tablet is taken out. It may be only during the period until the end or when the tablet sheet conveying mechanism and the tablet pressing mechanism are operating.

  As shown in FIG. 15, when viewed from the side, the ion irradiation nozzle 1501 is positioned not diagonally below the tablet to be taken out by the internal pressing body and the external pressing body but obliquely below. From there, the ions are irradiated obliquely upward toward the tablet sheet and the tablet to be taken out. In this embodiment, the irradiation angle is 45 ° upward.

This is because if the position of the ion irradiation nozzle is just below and near the bottom of the tablet to be taken out, when the tablet falls after being taken out of the tablet sheet, it does not fall on this nozzle, or it bumps and hits the nozzle. This is to prevent the package from being correctly packaged by dropping at an unintended timing.
FIG. 17 will be described.
FIG. 17 is a simplified diagram showing that a valve is provided in a duct provided inside the tablet supply device.

When the on-off valve 2201 is opened, ions generated in a specific tablet extraction unit are supplied, and when the on-off valve 2201 is closed, ions generated in the specific tablet extraction unit are blocked.

  That is, an opening / closing valve is provided in the duct so that the valve can be opened and closed arbitrarily. The tablet supply apparatus 10 of the present invention has 18 tablet extraction units, and the number of tablet extraction units used differs depending on the prescription. By opening and closing the on-off valve, it is possible to irradiate ions only to the tablet taking-out unit to be used.

  By restricting the tablet extraction unit irradiated with ions, the tablet extraction unit irradiated with ions can be efficiently and densely irradiated with limited ions generated by the ion generator. The neutralizing effect on the electrostatic charge on the sheet and the tablets to be taken out is enhanced.

  Reference numeral 2202 denotes a first supply pipe, which is a duct in which the ion generation unit 1411 and the air blowing unit 1412 communicate with a plurality of tablet extraction units. The generated ions are blown through the duct 1413 by the blower so that they can be collectively (simultaneously) supplied to the plurality of tablet extraction units via the first supply pipe 2202.

  Reference numeral 2203 denotes a second supply pipe, which is a duct in which the ion generation unit 1411 and the air blowing unit 1412 communicate with one or a plurality of tablet extraction units and communicate with a surface from which tablets are extracted from the tablet sheet.
