BACKGROUND OF THE INVENTION
The present invention relates to a medicine supply control method for controlling the supply of medicine onto a rotary table, and a packaging machine that divides and wraps medicines by a required amount.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, as a packaging machine that divides a medicine such as a powder into a required amount and packages it, a rotary packaging machine including a rotary table having an annular groove for dividing medicine is known. This packing machine is configured such that the medicine is distributed almost uniformly by a vibrating feeder into an annular groove of a rotary table that is rotated at a constant speed, and then the annular groove is formed by a cutting portion that rotates in a direction intersecting the annular groove. The medicine inside is cut out in accordance with the number of divisions, and the amount of the medicine thus cut out is packaged in a packaging portion disposed below.
[0003]
In this type of packaging machine, since it is required to distribute the drug almost evenly on the rotary table and perform stable drug division, for example, the conveyance of a vibrating feeder that supplies powder particles on the rotary table. The one configured to gradually increase the speed is known (for example, see Patent Document 1).
As another method, there is also known a method in which the drug is evenly distributed by increasing the rotation speed of the rotary table to increase the deposition speed in the annular groove.
[0004]

[0005]
[Problems to be solved by the invention]
However, in the configuration shown in Patent Document 1, it is difficult to perform uniform distribution when a small amount of medicine is supplied or when the medicine itself is coarse like a granule. There was a problem.
In the method of “increasing the rotation speed of the rotary table to increase the deposition rate in the annular groove”, the centrifugal force of the rotary table causes the drug to scatter to the surroundings regardless of the quantity and quality of the drug. The rotation speed cannot be increased beyond a certain value. If it does so, reliable distribution could not be performed, and there was a problem that it was necessary to take a long time for sprinkling the medicine (packaging time was increased).
Furthermore, in the packaging machine according to the prior art, the distance between the rotary table and the vibration feeder needs to be a certain value or more in order to secure the amount of medicine to be distributed to the rotary table. However, when this distance (falling distance) is long, there is a problem that when the medicine falls from the vibration feeder to the rotary table, the medicine jumps and the medicine cannot be uniformly shaken.
[0006]
Therefore, the present invention has been made to solve the above-described problems of the prior art, and is a medicine supply control capable of evenly distributing medicine without being scattered around, regardless of the quantity or quality of the medicine. It is an object to provide a method. Moreover, this invention makes it a subject to provide the packaging machine which can implement the said control method.
[0007]
[Means for Solving the Problems]
The present invention has been made to solve the above problems, and is a medicine supply control method for supplying medicine onto a rotary table by a vibration feeder, and detecting the height of the medicine supplied onto the rotary table. And a moving step of moving the vibration feeder to adjust the distance between the vibration feeder and the rotary table based on the detection result of the detection step.
[0008]
According to such a configuration, since the vibration feeder can move based on the detection result of the detection step, for example, when the medicine supply is started or when the amount of the medicine is small, the vibration feeder and the rotary table are disposed. When the medicine is dropped and supplied from the vibration feeder to the rotary table, the medicine can be prevented from splashing. In addition, since there is little splash of the medicine in this way, it becomes possible to increase the rotation speed of the rotary table and the medicine supply speed from the vibration feeder, so that the medicine packaging process can be performed with high accuracy and in a short processing time. It can be performed.
Further, according to such a configuration, the medicine of a predetermined value or more is supplied onto the rotary table in the detection result of the detection step (the position of the uppermost portion of the medicine is a predetermined value or more) If it is determined that the medicine drop distance from the vibration feeder can be increased, the medicine on the rotary table and the vibration feeder do not come into contact with each other. In such a case, since a predetermined amount of the medicine is supplied onto the rotary table, the medicine falls even if the medicine drop distance between the vibration feeder and the rotary table is set longer. Since it plays a cushioning role, the amount of the drug splashing is reduced. At this time, the rotation speed of the rotary table is set to such a speed that the medicine does not jump out of the rotary table.
In addition, according to such a configuration, in the case of a medicine having a size or shape that easily scatters according to the particle diameter or particle shape of the medicine, the distance between the vibration feeder and the rotary table is shortened.

[0010]
According to such a configuration, the rotation speed of the rotary table can be controlled based on the detection result of the detection step (that is, based on the drug amount on the rotary table). Thus, the rotary table can be rotated at a more appropriate rotational speed. Therefore, it is possible to perform an efficient packaging process of the drug with little splashing of the drug.
[0011]
Moreover, in the chemical | medical agent supply control method concerning this invention, the structure provided with the rotational speed raising process which raises the rotational speed of the said rotary table after the preset time passes since the supply start of the said chemical | medical agent is preferable.
[0012]
According to this preferable configuration, in the initial stage of supply in which the medicine is distributed so as to be in direct contact with the surface of the turntable, the rotation speed of the turntable is low. After that, when the rotation speed of the rotary table is increased after a preset time has elapsed, the medicine already supplied on the rotary table is applied to the base. Since it acts as a cushion, the medicine supplied thereon does not scatter around even if a centrifugal force based on the speed increase of the rotary table acts. Thus, stable distribution can be performed from the beginning to the end of the rotation of the rotary table, and the rotational speed of the rotary table is increased, so that the distribution speed can be improved and the work efficiency can be improved. it can.
[0013]
