Description

[Detailed description of the invention] [Industrial application field] This invention relates to a powder packaging machine.

[Prior Art] Generally, when powders are packaged using a powder packaging machine, the powders for one prescription are first prepared and then fed into a powder feeder such as an electromagnetic feeder, and then the powders are packaged little by little from the powder feeder. The supplied powder is distributed to a large number of compartments of the powder divider, and after this distribution work is completed, the powder is discharged one compartment at a time and is packaged by a packaging device.

[Problems to be Solved by the Invention] However, in such a conventional powder dispensing machine, it is not possible to feed the next powder into the powder feeder during the distributing work, and the dispensing of the powder cannot be carried out after the distributing work is completed. The next powder must be added to the powder feeder at the right time until the final powder is packaged.
Therefore, the task of adding powder to the powder feeder, which must be performed at the correct timing for each prescription, is the biggest bottleneck in automating powder packaging machines.

In addition, some formulations require the mixing of two or more types of powders, but some powders are difficult to mix, or even if mixed, they separate when placed on an electromagnetic feeder. However, when handling such powders, it is extremely difficult to distribute them evenly.

It is an object of the present invention to provide a powder dispensing machine which can solve the problems of the above-mentioned conventional machines, promote automation, and omit the work of mixing powders.

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a powder feeder,
A powder packaging machine comprising a powder processing device supplied with powder from the powder feeder, at least one auxiliary powder feeder supplying powder to the powder processing device, and a control device, the control device comprising: The powder feeder and the auxiliary powder feeder are operated in a sequential operation mode or a batch operation mode according to the order in which the powders are added to them.

[Function] By employing the above-mentioned means, the present invention facilitates automation by selecting the sequential operation mode, and eliminates the work of mixing powders by selecting the batch operation mode.

[Example] Embodiments of the invention shown in the drawings will be described below.

FIG. 1.2 shows an embodiment of the present invention, in which 1 is a powder processing device equipped with a powder divider 2, which has a large number of compartments 3.3, . . . They are arranged and configured to be rotatable, and the powder distributed to these compartments 3, 3, . . . is discharged one compartment at a time. 4
A is an electromagnetic feeder-type powder feeder that includes a hopper 5A into which powders are fed, and a trough 6A that conveys the powders fed into the hopper 5A by vibration and drops them from a nozzle at the tip; 4B is the same as the powder feeder 4A. It is an electromagnetic feeder-type auxiliary powder feeder equipped with a hopper 5B and a tiger 76B, and includes a powder feeder 4A and an auxiliary powder feeder 4.
B respectively rotate and move the powder divider 2 into the compartments 3 and 3.
3. The powder is distributed to... Reference numeral 7 indicates appropriate sensors 8A and 9A which are installed at the position directly below the hopper and the nozzle portion of the trough 6^ to detect the presence of powder in the powder feeder 4A, and the position directly below the hopper and the nozzle of the trough 76B. The control device 7 is equipped with similar sensors 8B and 9B installed at the auxiliary powder feeder 4B to detect the presence of powder in the auxiliary powder feeder 4B. When the powder is fed into the auxiliary powder feeder 4B while the powder is present, the sequential operation mode is selected, that is, when the operation of the powder feeder 4A is completed, the auxiliary powder feeder 4B is operated successively, and the powder feeder 4A is activated again. When powder is fed into the auxiliary powder feeder 4B without any powder present,
In the batch operation mode, both feeders 4 and 4B are operated at once after waiting for the powder to be fed into the powder feeder 4A. Further, the control device 7
After the sensor 8A detects the introduction of powder, the powder feeder 4
A is activated until the sensor 9A no longer detects the powder (that is, the period when the powder is present in the powder feeder 4A). An indicator (LED) 10A that indicates whether or not it can be fed, and an auxiliary powder feeder 4
A similar indicator 10B for B and both feeders 4A
, for example, a 7-segment LE that displays whether the operation mode of 4B is sequential operation mode or batch operation mode, etc.
It is equipped with indicators 11A and 11B consisting of D.

12 is a dust collection filter, 13 is a dust collector, 14 is each compartment 3
This is a packaging device that separates and packages the powder discharged from the hopper 15 through a hopper 15.

The above powder dispensing machine uses the powder feeder 4A as the main feeder during normal operation;
If powder is present in the auxiliary powder feeder 4B, both feeders 4A and 4B will operate in sequential operation mode, increasing the degree of freedom in terms of time for the powder feeding work and making it more automated. will be promoted. For example, when two types of powders are to be packaged together, one type of powder is first put into the auxiliary powder feeder 4B with no powder present in the powder feeder 4A,
If the other type of powder is subsequently fed into the powder feeder 4A, both feeders 4A and 4B will operate in the batch operation mode, which eliminates the need to mix both types of powder, and also allows both powders to be placed in one compartment. 3.3,... will be equally distributed.

In the above embodiment, the powder divider 2 is of a rotary type, but it may be of a linear type, for example, and the powder processing device 1 is of a type that divides the powder into compartments 3, 3, . . . It goes without saying that the present invention is not limited to the above embodiments, and that two or more auxiliary powder feeders 4B may be provided, and that the present invention can be modified in various ways to the above-described embodiments.

[Effects of the Invention] Since the present invention is configured as described above, the next powder can be fed into the auxiliary powder feeder even when the powder feeder is in the process of distributing the powder, thereby increasing the degree of freedom in the timing of powder feeding work. In addition, if the powder feeder and auxiliary powder feeder are operated at once, the work of mixing powders can be omitted, and the powder feeder and auxiliary powder feeder You can arbitrarily select between sequential operation mode and batch operation mode by simply changing the order in which powders are added to the machine.
Therefore, it has excellent effects such as being able to automate switching of operating modes.
