Abstract
Abstract A tablet packing device is proposed which accommodates a plurality of types of tablets and selectively discharges them from feeders for packing. A tablet is discharged from one of the feeders into a hole formed in a pocket plate. Since a shutter plate covers the hole, the tablet bounces on the shutter plate and settles down after a while. Thereafter, the shutter plate is rotated to open the hole to drop the tablet to a hopper. The tablet is then slid down along the inner wall of the hopper and, when a hopper cover provided at the bottom of the hopper is opened, it is dropped further therethrough. After the tablet has reached inside of the packing sheet which is folded into two, it is sealed in one packing bag as the heater rollers rotate. It is possible to save the time required to pack the tablets according to the tablet types by presetting the time required for each type of tablet to settle down from landing and discharging the tablet after lapse of the preset time.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
109 words
A tablet packing device having a plurality of feeders accommodating different types of tablets, said tablets being selectively dropped from said feeders and packed, said packing device further comprising: memory means for storing data of a time period for each type of tablets to settle down from the instant when a dropped tablet has landed; and control means for controlling said feeders to discharge one of said tablets from one of said feeders, to read out said time period specified for said one tablet from said memory means, and to drop the next one of said tablets from another one of said feeders after said time period has lapsed.
Claim 2
Dependent Claim
109 words
A tablet packing device having a plurality of feeders accommodating different types of tablets, said tablets being selectively dropped from said feeders and packed, said packing device further comprising: memory means for storing data of a time period for each type of tablets to settle down from the instant when a dropped tablet has landed; and control means for controlling said feeders to discharge one of said tablets from one of said feeders, to read out said time period specified for said one tablet from said memory means, and to drop the next one of said tablets from another one of said feeders after said time period has lapsed.
Claim 3
Independent Claim
84 words
A method for controlling a tablet packing device, said tablet packing device having a plurality of feeders accommodating different types of tablets, said tablets being selectively dropped from said feeders and packed, said method comprising steps of: determining beforehand a time period for each type of tablet to settle down from the instant when the tablet has been dropped; and determining a timing for dropping a second tablet after a preceding tablet is dropped from one of said feeders based upon said time period.
Claim 4
Independent Claim
84 words
A method for controlling a tablet packing device, said tablet packing device having a plurality of feeders accommodating different types of tablets, said tablets being selectively dropped from said feeders and packed, said method comprising steps of: determining beforehand a time period for each type of tablet to settle down from the instant when the tablet has been dropped; and determining a timing for dropping a second tablet after a preceding tablet is dropped from one of said feeders based upon said time period.
Claim 5
Dependent Claim
51 words
A method for controlling a tablet packing device as claimed in claim 2, wherein a timing to drop said tablet is determined by said time period and by a time period starting from the instant when the tablet is discharged from one of the feeder to the instant when it lands.
Claim 6
Dependent Claim
39 words
A method for controlling a tablet packing device as claimed in claim 2, wherein said time period for the tablet to settle down is calculated according to the height between the feeder accommodating said tablet and the landing point.
Claim 7
Dependent Claim
63 words
A tablet packing device having a plurality of vertically separated feeders accommodating different types of tablets, said tablets being selectively discharged and packed, characterized in that said tablets are categorized into groups according to the time required to settle down after they are dropped, and that the sooner the tablets settle, the tablets are accommodated in the higher of the vertically separated feeders.
Claim 8
Dependent Claim
63 words
A tablet packing device having a plurality of vertically separated feeders accommodating different types of tablets, said tablets being selectively discharged and packed, characterized in that said tablets are categorized into groups according to the time required to settle down after they are dropped, and that the sooner the tablets settle, the tablets are accommodated in the higher of the vertically separated feeders.
Claim 9
Dependent Claim
74 words
A tablet packing device having a plurality of feeders accommodating different types of tablets, said tablets being selectively discharged and packed, characterized in that said tablets are categorized into groups according to the time required to settle down after they are dropped and the frequency in use, and that the sooner the tablets settle and the less frequently the tablets are used, the tablets are accommodated in the higher of several vertically separated feeders.
Claim 10
Dependent Claim
74 words
A tablet packing device having a plurality of feeders accommodating different types of tablets, said tablets being selectively discharged and packed, characterized in that said tablets are categorized into groups according to the time required to settle down after they are dropped and the frequency in use, and that the sooner the tablets settle and the less frequently the tablets are used, the tablets are accommodated in the higher of several vertically separated feeders.
