Description

Detailed Description of the Invention (Industrial Field of Application) The small portions of the drug packaging device of the present invention I''i enable drugs to be accurately placed into compartments of successive parcel packaging bags. This invention relates to a method for packaging drugs.

(Prior art) In order to provide prepared drugs to patients at hospitals, clinics, etc., recently prepared powders, tablets, or capsule drugs are individually packaged according to the prescription.
Alternatively, they are combined and packaged or supplied by various means. As for this packaging method, some methods have already been adopted to package VC powders and tablets or capsules for a single dose, as described above. , a method has been adopted in which tablets and medicines in capsules (hereinafter simply referred to as capsules) are packaged separately, and these dispensed medicines are transferred to a series of continuous packaging machines (hereinafter referred to as medicine packaging machines). After the medicine is packaged and packaged one by one, the prescription is given to the patient.

The continuous type drug packaging IIk Tokoatsu-C normally uses a method in which a roll of wrapping paper of the required width is pulled out one after another and the drug is put into the packaging compartment while forming a bag. The type of bag that accepts the medication while forming the bag at an angle has generally achieved its purpose by taking precautions to prevent the powder from scattering. When adding drugs sequentially into the packaging bag,
A situation often arises in which the opening is sealed before the medicine can be fully inserted into the interior, and as a result, the powder is scattered and adhered to the sealed part of the opening, making it impossible to completely seal it, and sometimes the tablets that were supposed to have been inserted or The capsule climbs up to the seal part and is compressed by the hot platen for seal operation, causing the capsule to collapse at the open seal part, resulting in accidents such as not only being unable to seal, but also the inability to package the capsules themselves. there were.

This phenomenon can be solved by first folding the packaging paper in half in the longitudinal direction and pulling it out from the take-up roll with the folded side facing down, then vertically sealing the first section at the required intervals, and then vertically sealing the first section. The lower chute of the hopper or the lower part of the charging cylinder is pushed into the bag divided by the hopper to open it, and the bag is divided, so to speak.

Since the medicine has to be thrown into a series of open bags by force, the medicine must be thrown into the bag without any space left inside. The drug that is put into the bag does not reach the bottom of the bag, but moves to the next opening seal (lateral seal) and is sealed.As a result of step i, the above-mentioned inconvenience occurs. However, despite these problems, the current situation is that no solution has been found.

(Objective of the Invention) The present invention solves these conventional problems without taking complicated measures, and makes it possible to reliably put any drug into the compartmented bag and to open the bag. Insert the seal of the
The object of the present invention is to provide a method for packaging drugs that can be carried out in a highly efficient manner without causing problems such as scattering of powdered medicines or breakage of tablets, etc.

(Structure of the Invention) In order to achieve a certain object, in the present invention, a packaging paper for drug packaging that is folded in half and continuous at °C is moved intermittently linearly with the folded side facing down. In a drug packaging machine, a required amount of drugs is introduced into a bag made by sequentially forming partitions through an input gate, and then the opening is sealed and sent out. is always interposed between the inner edges of the opening side of the continuous packaging bag, and after advancing the continuous wrapping paper for the required length, clamping the wrapping paper at the pre-advancement position of the sachet partition section at the medicine injection position, and At the rear position, a pair of rolls overfeeds the required amount to actively bulge the bag-forming opening, and then the drug injection force is lowered to introduce the drug into the sachet partition section. I made it.

In the method of the present invention, the relationship between the drug injection position, the clamp of the packaging paper, and the overfeed roll is as follows:
A pair of heat-sealing rolls for separating packages is provided in front of the paper feed side of the medicine input position (backward in the direction of travel of the wrapping paper), and the wrapping paper is clamped at a position in front of this roll, and the heat-sealing roll is The packaging partition is formed by a seal roll, and by overfeeding the opening of the roller packaging partition section, the opening bulges out, allowing the drug input gate to be easily inserted between the packaging partitions. .

In addition, in the method of the present invention, the relationship between the other drug input positions and the clamps and tV overfeed rolls of the packaging paper is determined after forming the portions for dividing the packaging into required dimensions, that is, after manufacturing the packaging bags as a continuous bag. The drug injection position is set at an appropriate position after bagging, and after the packaging bag is clamped at the front position in the direction of travel, a pair of overfeed rollers overfeed the required amount at the rear position, allowing the drug injection gate to be easily inserted. So do it.

In the present invention, the operations of each part are all interlocked and performed in a predetermined order, and the order of operation is set so as to allow smooth packaging without interfering with the packaging work.

(Example) Hereinafter, the method of the present invention will be described in detail with reference to the drawings based on an example. Fig. 1 shows the method of the present invention in which overfeeding is carried out using a heat-sealing roll for separating packages. It is an exploded perspective view of the packaging main part of the drug packaging machine to be adopted, in which the packaging paper (A) which has been folded in half so as to form the required continuous stack is placed with the folded side facing down from the winding roll 11) and is tensioned with a known structure. The tension is kept constant by the adjustment roll mechanism +21 [It is designed to be supplied from bag making to the packaging work side, and there is a heat seal roll mechanism for vertical packaging partitions at a position before the medicine input position (7) (3), and a drug input gate (11) is arranged in the upper part of the front position so as to be movable up and down. The QC drug input gate 1111 is a cylindrical body of an appropriate length with both sides of the lower half cut obliquely so as to be interposed between the two folds of the packaging paper (4), and is connected to the lifting operation mechanism Ill. A series of supports (1) are attached to the upper part of which the hopper I connects its gate tube to the input gate Il.
&C so as to fit loosely into the inside of the container and move vertically differentially, and these constitute a drug inputting section (10).

Then, just at the front position in the direction of travel of the wrapping paper from the medicine input position (g) according to the medicine input part (lt), the packaging partition part (a)
A clamp (4) is placed at a position corresponding to
notch θtutter 16), opening of packaging bag with medicine loaded (b) heat seal mechanism (6), clamp +4'l,
The rollers (7) for feeding out the divided continuous packaging bags are arranged in order, and the packaging paper (A) is kept horizontal with the fold facing down from the take-up roll (1) to the feeding out of the divided continuous packaging bags. The cylinders are moved in a straight line and the packaging is carried out sequentially at °C.

The timing is set so that all of the operations in each part operate intermittently and sequentially according to a preset program.The one shown in °C in this example is a system using a cam. However, a part of t is shown in an exploded view, and there is a VC so that the power from one drive motor is distributed to each part for operation. In addition, (2+1 is the operating cam mechanism for traverse operation of opening lower part heat seal @ structure (6), (A) is the opening heat sealing mechanism 1B) hot plate mounting is piece 16') opening/closing drive mechanism, The transverse guide support of the heat-sealing mechanism (8) is a drive shaft for the clamp operation and the heat-sealing roll mechanism for separating packages, and the drive shafts are respectively branched from the motor. (f) is a drive unit for the heat seal roll.

Of course, after this packaging, a device (not shown) is provided at the top for dispensing the medicine and feeding it into the hopper (2).

Next, to explain the method of the present invention using such a drug packaging machine, when the required amount (amount of one package) of drugs prepared at °C according to the prescription in the medical record are sequentially supplied to hopper I, the volume is When the leading part of the loading paper (4) consisting of the take-up roll 11) is kept under tension due to the rotation of the group of feeding rollers (7) and travels the required distance (length equivalent to 1 minute wrapping), -1 When the feeding of the packaging paper (G) stops, the clamps (4) and the heat-sealing roll mechanism (3) for packaging partitioning, which are placed before and after the medicine input position (7), stop the movement of the packaging paper (G) from floating. After that, the first clamp (4) operates to clamp and fix the upper part of the packaging paper (G) at the sealing part position for the preceding packaging partition that has already been sealed, and then heat sealing is performed a little later. Heat seal roll (3) of roll mechanism (3)
One pair just makes contact with the packaging paper (A), pinches it, and rotates, and the packaging paper is clamped at the front position as described above, and the rear Ift is moved to the heat seal roll (A). 3) Rotation displacement of the heating part of the heat seal roll from the position where it pinches the packaging paper (4) to the position where it leaves the wrapping paper (4) as shown in Fig. 3G by the same pressing action by the heating part of (3). At the same time, the pincers are heat-sealed to form the packaging partition (a), so that the opening (b) is actively moved from side to side at the same time as the bag is being made. Expanded in a bulging state (with respect to the direction of travel). Therefore, the drug injection gate (111), which operates in the following order of operation, can enter the inside of the bag (wrapping paper) in a natural state without forcing the opening (b) wide. The drug that is supplied into the hopper 114) is fed into the hopper 114) through the input gate (11) through the gate tube connected to the hopper outlet, and is then fed into the hopper 114). When they are of the same shape, such as capsules, the inner pocket between the sachets is swollen, allowing them to fall to the bottom of the bag and remain in the middle of the bag, allowing the medicine to be poured into powdered medicine (granules). Even in the case of solid materials, it is necessary to guide the insertion at the bottom of the bag at the input gate og.
By applying vibration to the drug 14 so that it is lowered when the drug is introduced, it is possible to reliably fill the divided packages ω without causing noise in the hopper gate tube or adhering and remaining on the input gate l111.

After completing the drug injection operation, the drug injection gate U+ is first opened.
1 and the hopper (141) are rapidly raised by the operation of the lifting operation mechanism (1~), and the lower flat part of the input gate (+1 +l
Only the paper (4) remains in the opening (b) of the packaging paper (4), and at the same time, the rotation of the drive @quadruple theta (c) Clamping with dynamic displacement (4
) ++5 is operated to release the clamp, and then the group of feeding rollers (7) is driven to rotate and stops feeding out the °C packaging paper (G) (one movement after pinching the already wrapped ■4) to the required length. do. In this way, when the packaging paper and the connected bundles of pre-packaged paper are fed out with a predetermined size, the clamp 14) is activated again in the same manner as described above, and then the drug input position c7) # is moved. The clamp 14) is activated to temporarily fix the packaging tube, and thereafter the above operation is repeated to ensure smooth drug injection. In addition, in this embodiment, the heating plate of the opening heat sealing mechanism (6) is attached to the opening (b) at the second pitch after the medicine is put between the sachets.
It travels while being compressed with 'l' and is heat-sealed, and is delivered after packaging (the mechanism (6) returns to its original state once the opening is sealed). The incision cutter (5) is configured to selectively make a distinguishing incision in the packaging partition part (a). The amount of cut is selected by a cam with an electromagnetic clutch t271, =, which is shown by a chain line, between a cam that increases the amount of operation of the cutter (5) and a cam that requires less amount of operation, and operates the cutter via a link mechanism. It's like that.

In accordance with the spirit of the present invention, in addition to the above-mentioned method, the relationship between the drug input position and the packaging partition shape position is shown in FIG.
As shown in the figure, after first heat-sealing the partitions for each packet to form bags, the next position is to use a pair of overweed rolls (c) to transfer the packaged packaging paper to the drug transfer position (7). By overfeeding and temporarily fixing at the front position with the clamp I4), it is possible to obtain the same effect as explained using the above-mentioned specific example. In this method, the timing of sealing by the heat-sealing roll (31) of the partition heat-sealing mechanism is set so that the wrapping paper is not pulled together, but rather is fed gently toward the overfeed roll side in response to the rotation of the overfeed roll. It is preferable to set the moving speed of the wrapping paper on the rear side so that

In addition, the medicine injection position and the heat-sealing mechanism for the opening may be provided adjacent to each other, and in this case, the operation timing of the heat-sealing mechanism may be shifted so as not to interfere with the operation of the clamp, as described above. This allows for reliable packaging. .

Of course, the method of the present invention is not limited to the apparatus described in the above-mentioned embodiments, and can be applied to any laterally moving type packaging machine by arranging the related operations of each operating part. .

(Effects of the Invention) According to the present invention, when the packaging paper is continuously folded in two and is used to continuously package various drugs, when the packaging paper is fed to the drug input position, In the step of step 1, the front side of the dividing package in the direction of travel is clamped and temporarily fixed, and an appropriate amount of overfeed is applied on the side near the input position, thereby actively feeding the opening of the divided package after being made into bags. The drug injection guide can be pushed into the bag easily by pushing it open using the Therefore, when sealing the opening after ℃°C, smooth packaging can be carried out continuously without interfering with the sealing at the sealing part and without damaging the drug. It was.
