Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a controller for a tablet packing machine having a large number of tablet feeders.

[Prior Art] Generally, a tablet packing machine of this type sequentially discharges tablets one by one from a tablet feeder containing tablets to be packed, and then packs each tablet. It is something like this.

 On the other hand, it is desirable that the processing speed of the tablet packing machine is high, because the time required for packing the discharged tablets is shortened and the time required for discharging the tablets from each tablet feeder is shortened. It is necessary to reduce the number of tablets, especially when it is necessary to discharge multiple tablets for one packaging, such as when packaging multiple tablets of the same type in one package. It is desired to reduce the time required for the tablet discharging operation and thus achieve a higher processing speed.

[Problems to be Solved by the Invention] However, in the conventional tablet packing machine, in order to eject one tablet from the tablet feeder, for example, an input device directly transmits a necessary operation signal to the tablet feeder, and the tablet feeder is operated. It is necessary to operate the feeder and transmit the detection signal of the tablet discharged by the tablet feeder directly from the tablet feeder to the input device. Therefore, discharging one tablet inevitably takes a considerable time. Moreover, in the past, different types of tablets were stored in each tablet feeder, and the tablet discharging operation of each tablet feeder was individually controlled. Therefore, for example, 3 tablets of the same type in one package When it is necessary to discharge multiple tablets for one packaging, such as in the case of packaging, the time required for the discharge is multiple times the discharge time of one tablet ( It will take about 3 times as much) and if such multiple tablets are repeatedly packed, the tablet feeder will empty in a relatively short time, so tablets must be replenished frequently. However, if the number of times of replenishment is large, the time required for the replenishment becomes long as a whole, and there is a problem that it hinders an increase in processing speed.

 The present invention solves the problems of the above-mentioned conventional ones, and the processing speed of the tablet packaging machine, in particular, one packaging such as a case where a plurality of tablets of the same type are packaged in one packaging body. It is an object of the present invention to provide a control device for a tablet packing machine, which can shorten the time required for the tablet discharging operation in the case of having to discharge a plurality of tablets for use in tablets and thereby increase the processing speed. It is a thing.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a tablet packing machine equipped with a plurality of tablet feeders, which is provided with means for inputting packing information for tablets to be packed, The tablet feeder is classified into a plurality of groups and the packaging information is assigned to each group, and based on the packaging information assigned by the central processing means, each individual belonging to the group The tablet feeder is provided with control means for performing a predetermined tablet discharging operation.

[Operation] By adopting the above means, the present invention applies the operation signal necessary for causing each tablet feeder to perform a predetermined tablet discharging operation and the tablet detection signal to the tablet feeder and the tablet feeder to which the operation signal belongs. It only needs to interact with the control means of the group, which simplifies the transmission content between the input means and the centralized processing means, shortening the time required for the tablet ejection operation as a whole, and as a result Therefore, the processing speed of the tablet packaging machine will be improved.
