It is accommodated in the storage chamber 14a. In addition, when the tablet division moving container 14 is guided and moved to the guide rails 13, and each of the tablet storage chambers 14a reaches a predetermined tablet drop position, each tablet storage mechanism is opened by a cover opening and closing mechanism (not shown). The opening / closing cover of the bottom of the chamber 14a opens, and the tablet in the tablet storage chamber 14a falls downward.

A powder hopper (not shown) is disposed below the powder storage chambers 9b and 9c, and a tablet hopper (not shown) is disposed below the powder storage chamber 14a. The lower end part is connected to the chute 15 for chemical | medical agent injection into the packaging sheet | seat of the packaging apparatus 4. As shown in FIG.

In the chemical | medical agent distribution apparatus comprised in this way, especially the distribution operation (normal distribution operation) of powder is demonstrated below. In the distribution of this powder, first, after adjusting the position of the partition plate 8a in the V-shaped hopper 8 in accordance with the distribution number of the powder, the powder is supplied into the V-shaped hopper 8, and the After the surface of the powder is made even, the opening and closing plate which forms the side wall of this V-shaped hopper 8 is rotated, and each powder storage of the powder-containing body 9 which waits for the powder in the V-shaped hopper 8 below is carried out. It falls in the chambers 9b and 9c.

Next, the endless belt is driven so that all the powder storage bodies 9 retreat once from the powder dropping position located at the center of the shelf board 3, and then the endless belt is intermittently driven in the reverse direction to place the powder placed at the tip end. Each powder container body 9 is sequentially moved from the housing body 9 to the powder dropping position. In this way, when each powder storage chamber 9b, 9c reaches the predetermined powder dropping position, the opening-closing cover 10 is operated in the opening direction by operation of a cover opening / closing mechanism, and thereby powder storage chambers 9b, 9c The bottom part of the bottom) is opened, and the powder in these powder storage chambers 9b and 9c falls below, and the powder is supplied from the powder hopper to the packaging apparatus 4 via the chute 15.

On the other hand, in the packaging apparatus 4, the packing sheet is unwound from the roll body 4a at the same timing as the powder falling, and accommodates the powder falling by this packing sheet, and the opening of the packing sheet is continuously opened by the sealing means. Packaging is performed by sealing with. In this way, the moving means (endless belt) for intermittently driving the powder storage body 9 and the sealing means for sealing the opening of the packing sheet are controlled by control signals from control means (not shown), so that both of them smoothly interlock with each other. The distribution operation is performed.

Here, in the normal distribution operation (normal mode), the opening and closing control of the opening and closing lids 10 and 10 in the powder storage chambers 9b and 9c is performed in the order shown in Figs. 4A to 4D. Is done accordingly. In addition, in FIG. 4, the case where 4 bags are distributed is illustrated, and for convenience of description, it is 9 ₁ , 9 ₂ , 9 ₃ ,... In order from the front end side to the powder storage chambers 9b and 9c. … Is indicated.

First, in the first batch operation, the opening / closing lid 10 in the leading powder storage chamber 9 ₁ is opened so that the powder in the powder storage chamber 9 ₁ falls downward (Fig. 4 (a)). ). Next, in the second distribution operation, the powder storage compartment is moved by one pitch, and then the opening and closing cover of the leading powder storage compartment 9 ₁ together with the opening and closing cover 10 of the _second powder storage compartment 9 ₂ . (10) is opened, and the powder in the powder storage chamber 9 ₂ falls downward, and the powder remaining in the _first powder storage chamber 9 ₁ does not drop by the first opening operation. (FIG. 4B). Similarly, the distribution behavior of the three pojjae again powder storage chamber is moved by one pitch, the opening and closing cover 10 of the powder compartment ₍₉₂₎ with the opening and closing cover 10 of the powder compartment ₍₉₃₎ opening The powder of the third powder storage chamber 9 ₃ falls downward, and the powder remaining in the _second powder storage chamber 9 ₂ does not drop entirely by the first opening operation (FIG. 4). (C)). In this way, in the intermediate distribution operation, the powder is reliably dropped by two openings. In the fourth (last cell) distribution operation, two pitches of the fourth powder storage chamber 9 ₄ are moved by two pitches in order to reliably recover the residues spilled on the powder storage chamber 9 ₅ side during powder division. The opening and closing cover 10 of the fifth powder storage compartment 9 ₅ is opened together with the opening and closing lid 10, and the powder in the powder storage compartment 9 ₄ falls downward, and the powder storage compartment 9 ₅ is opened. The remaining medicine drops (Fig. 4 (d)).

By the way, in the chemical | medical agent distribution apparatus of this embodiment, apart from the normal distribution operation (normal mode) mentioned above, the powder contained in the two powder storage chambers 9b and 9c is packaged in one distribution bag. The mode (two bucket mode) is selectable by transmitting a selection signal to the control means by an operation such as an operation switch. This two-bucket mode is applied to special medicines and the like in which the amount of powder to be distributed in one bag of distribution exceeds the volume of one powder storage chamber 9b, 9c.

The selection processing of the normal mode (one bucket mode) and the two bucket mode is performed in accordance with the flowchart shown in FIG. Hereinafter, this flowchart is demonstrated.

A: It is determined whether two bucket modes are selected by the user.

If B to C: 2 bucket mode is not selected, normal distribution processing is executed when the start key is turned ON. In addition, this normal distribution process is performed by the procedure demonstrated in FIG.

When D: 2 bucket mode is selected, the number of half of the set catcher (the number of sets to the powder divider 11) is set as the distribution number.

E: It is judged whether or not the set distribution number is an integer, and when it is not an integer (when the distribution number is not divided completely), the flow is regarded as a defective set and the flow ends.

F to G; if the distribution number is an integer, it is determined next whether the start key is ON or not, and if it is ON, the two bucket distribution processes described later are executed.

Next, the above-described two bucket distribution processing will be described in more detail with reference to the flowchart shown in FIG. 6 and the operation explanatory drawing shown in FIG.

G1: The opening / closing plate of the V-type hopper 8 is opened and closed, and the powder in the V-type hopper 8 is dropped into the powder storage chamber of the powder divider 11 waiting downward.

G2: The powder divider 11 is moved to the start position (a position where all the powder storage bodies 9 retreat from the powder dropping position) by the operation of the moving means.

G3: Turn on the seal motor of the packaging device (4).

G4 to G5: The powder divider 11 is advanced by two bags (by two pitches), and each opening and closing cover of the first and second powder storage chambers 9 ₁ and 9 ₂ as shown in Fig. 7A. Open (10, 10).

G6 to G7: It is determined whether the remaining distribution number is one. If the number is not one, the catcher is reduced by one.

G8: In order to reliably drop the powder adhering to the surface of the powder hopper, a vibration is applied to the hopper (in-situ hopper hitting). After this step, the process returns to step G4 again, and the step G4 or less is repeated. Thus, as shown in Figs. 7A to 7D, the powder storage chambers 9 ₁ , 9 ₂ → powder storage chambers 9 ₃ , 9 ₄ → powder storage chambers until the final fabric is reached. 9 ₅ , 9 ₆ ) → powder storage chambers (9 ₇ , 9 ₈ ) are sent in two batches, and powder of two distributions (for two powder storage chambers) falls downward.

In the judgment of G9 to G11: step G6, when the remaining number of catchers becomes 1 (the last catcher), the catcher is reduced by 1, the hopper of the final gun is struck and the seal motor is turned OFF.

G12 to G14: Subsequently, in order to reliably recover the residues spilled on the powder storage chamber 9 ₉ side, the powder divider 11 is advanced by the remaining chemicals, and the opening and closing cover 10 of the powder storage chamber 9 ₈ is used. ) And the opening and closing cover 10 of the powder storage chamber (9 ₉ ) is opened (Fig. 7 (e)). After that, the hopper of the final fabric is hit again. 7 illustrates the case where four bags are distributed.

G15: Finally, the fear processing is performed. This fear process refers to a process based on a preset fear setting (e.g., setting a fear part in which drugs are not enclosed between patient A and patient B).

Thus, in this embodiment, since it is comprised so that the powder divider 11 may advance for two distributions with respect to one distribution, it can operate similarly to a normal mode, without pausing about a seal motor. Therefore, there is an effect that two-bucket mode can be implemented without lowering the distribution speed. However, in this embodiment, when the distribution speed becomes too high, the powder may be caught in the seal portion, so it is necessary to set the distribution speed at an appropriate speed.

Next, another embodiment of the two-bucket distribution process will be described with reference to the flowchart shown in FIG. 8.

G101: The opening / closing plate of the V-type hopper 8 is opened and closed, and the powder in the V-type hopper 8 is dropped into the powder storage chamber of the powder divider 11 waiting below.

G102: The powder divider 11 is moved to a start position (a position where all powder storage bodies 9 retract from the powder dropping position) by the operation of the moving means.

G103: The seal motor of the packaging device 4 is turned on.

G104 to G105: The powder splitter 11 is advanced by one packet (1 pitch), and the opening / closing lid 10 of the powder storage compartment is opened.

G106 to G107: After sealing the hopper in position, turn off the seal motor.

G108 to G110: It is determined whether the remaining distribution number is 1 bag, and if it is not 1 bag, the powder divider 11 is advanced by 1 distribution (1 pitch), and the opening / closing cover 10 of the powder storage room is opened. Open.                     

G111 to G112: After hitting the hopper in position, the catcher is reduced by one, and the process returns to step G103 and the steps G103 and below are repeated. Further, the advance of the pitch of the powder divider 11 and the opening and closing of the opening and closing cover of the powder storage chamber are performed in the same manner as in the above-described normal mode, so that the powder is reliably dropped by two openings of the opening and closing cover 10.

G113 to G114: In the determination of step G108, when the remaining number of catches is 1 (the final catch), the powder splitter 11 is advanced in 2 portions (2 pitches) and two powder storage chambers are carried out as in the normal mode. The opening and closing cover 10 of the operation to drop the remaining.

G115 to G116: Final hopper beating reduces the catcher by one.

G117: Finally, fear processing is performed.

Thus, in this embodiment, since the powder divider 11 is advanced for one distribution and the seal motor is temporarily stopped, the distribution speed decreases somewhat, but the stable seal is stable regardless of the distribution speed. There is an effect that it can be done.

In each of the above embodiments, a powder has been described as an example. However, the present invention can also be applied to the case of distributing tablets or to distributing tablets and powders at the same time.

In each of the above embodiments, the powders (or tablets) in the two powder storage compartments are packaged in one distribution unit, but the powders (or tablets) in the three or more powder storage compartments can be packaged in one distribution unit. have.

According to the present invention, since the medicines stored in the plurality of medicine storage chambers (a powder storage chamber or a tablet storage chamber) are dropped and supplied into one bag of envelopes, the medicines to be distributed in one distribution unit according to the type of medicine should be distributed. Even when the quantity of the drug cannot be stored in one drug storage chamber, the required amount of the drug can be distributed in one distribution unit as required.
