Description

TECHNICAL FIELD The present invention relates to a powder packaging machine.

[Prior Art] Generally, in the case of packaging a powder with a powder packaging machine, first, a prescription powder to be packaged is dispensed, and this is put into a powder feeder such as an electromagnetic feeder, and then the powder feeder is used little by little. The supplied powder is distributed to a large number of compartments of the powder divider, and after the distribution work is completed, the powder is discharged into each compartment and packaged by a packaging device.

[Problems to be Solved by the Invention] However, in such a conventional powder-dispensing and packaging machine, the next powder cannot be fed to the powder-feeder during the powder-distributor distribution work, and the powder-dispersion dispenser is distributed after the distribution work is completed. It is necessary to add the next powder to the powder feeder at an appropriate timing by the time the packaging work of the powder is completed.
For this reason, the work of introducing the powder into the powder feeder, which must be performed at each time for each prescription, is the biggest bottleneck in automating the powder packaging machine.
In addition, some prescriptions must be mixed with two or more powders, but some powders are difficult to mix, or even if mixed, they separate when applied to an electromagnetic feeder. However, when handling such powders, it is extremely difficult to evenly distribute the powders.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the problems of the above-mentioned conventional ones, to promote automation, and to provide a powder packaging machine capable of omitting a powder mixing operation.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a powder feeder,
In a powder packaging machine comprising a powder processing device supplied with powder from the powder feeder, at least one auxiliary powder feeder for supplying powder to the powder processing device, and a control device are provided, and the control device is The powder feeder and the auxiliary powder feeder are operated in a sequential operation mode or a batch operation mode in accordance with the order of the powder to be charged therein.

[Operation] By adopting the above means, the present invention facilitates automation by selecting the sequential operation mode, and can omit the powder mixing operation by selecting the batch operation mode.

[Embodiment] An embodiment of the present invention shown in the drawings will be described below.

1 and 2 show an embodiment of the present invention, in which 1 is a powder processing apparatus having a powder divider 2, and the powder divider 2 has a large number of compartments 3, 3, ... Arranged in an annular shape. Are configured to be rotatable, and the powder distributed in these compartments 3, 3, ... Is discharged for each compartment. 4A is a hopper 5A into which the powder is put, and a trough 6A that conveys the powder put into the hopper 5A by vibration and drops it from the nozzle at the tip.
Electromagnetic feeder type powder feeder with 4 and 4B is an electromagnetic feeder type auxiliary powder feeder with hopper 5B and trough 6B like powder feeder 4A, and powder feeder 4A.
The auxiliary powder feeder 4B is adapted to distribute the powder to the compartments 3, 3, ... In conjunction with the rotation of the powder divider 2. 7 are appropriate sensors 8A and 9A arranged at the position directly below the hopper and the nozzle portion of the trough 6A to detect the presence of the powder in the powder feeder 4A, and the position directly below the hopper of the trough 6B and the nozzle portion. Is a control device provided with the same sensors 8B and 9B for detecting the presence of the powder in the auxiliary powder feeder 4B when the powder is supplied to the powder feeder 4A. When the powder is added to the auxiliary powder feeder 4B in the existing state, the auxiliary powder feeder 4B is continuously operated after the continuous operation mode, that is, when the operation of the powder feeder 4A is finished, and the powder is supplied to the powder feeder 4A. When the powder is added to the auxiliary powder feeder 4B in the absence of the powder, the batch operation mode, i.e., waiting for the powder to be continuously charged to the powder feeder 4A, both feeders 4A and 4B are operated together. It It is designed to let you. In addition, the control device 7 operates from the time when the sensor 8A detects the introduction of the powder to the time when the powder feeder 4A operates and the sensor 9A stops detecting the powder (that is, the powder feeder).
Indicator (LED) 10A that indicates whether or not powder can be added to the powder feeder 4A by turning on the light while the powder is being supplied to 4A and existing for the rest, and the auxiliary powder feeder. A similar indicator 10B for 4B and indicators 11A, 11B consisting of, for example, 7-segment LEDs for indicating whether the operation mode of both feeders 4A, 4B is the sequential operation mode or the collective operation mode are provided. I am. 12 is a dust collecting filter, 13 is a dust collector, and 14 is a packaging device for packaging the powder discharged from each compartment 3 through a hopper 15.

The above powder dispensing machine uses the powder feeder 4A as the main feeder during normal operation, and if powder is present in the powder feeder 4A, the powder is fed to the auxiliary powder feeder 4B, and both feeders 4A and 4B are Since the operation is performed in the successive operation mode, the degree of freedom in time of the powder charging operation is increased, and the automation is promoted accordingly. Also, for example, when packing two types of powders together,
First, the auxiliary powder feeder with no powder in 4A
If one type of powder is put into 4B and then the other type of powder is put into the powder feeder 4A, both feeders 4A and 4B will operate in a batch operation mode, so mixing operation of both powders is omitted. You can do it, and both powders are compartments 3,
It will be evenly distributed to 3, ...

In the above embodiment, the powder divider 2 is of the rotary type, but it may be of the linear type, for example, and the rotatable powder divider 2 is composed of a large number of compartments 3, 3 ,. Instead, the powder supplied from the powder feeders 4A, 4B to the turntable having a mounting surface that is not divided into an annular shape is divided into hoppers 15 by an angle corresponding to a predetermined division number by an appropriate cutting member. Needless to say, the auxiliary powder feeder 4B may be provided in a number of two or more. In addition, the present invention can be modified or modified in various ways in the above embodiment.

[Advantages of the Invention] Since the present invention is configured as described above, the next powder can be charged into the auxiliary powder feeder even when the powder feeder is performing the distribution work, and therefore the flexibility of the timing of the powder charging operation is improved. This will increase the automation of the powder packaging machine, and if the powder feeder and the auxiliary powder feeder are operated together, the powder mixing operation can be omitted, and the powder feeder and the auxiliary powder feeder can be omitted. It is possible to arbitrarily select the sequential operation mode and the batch operation mode by simply changing the order of feeding the powder to be charged to
Therefore, it has an excellent effect that the switching of the operation modes can be automated.
