FIG. 4 is a plan view of FIG. 3, FIG. 5 is a longitudinal sectional view of the tablet loading device of FIG. 1 showing the receiving state of the tablet while the tablet is moving backward, FIG. 6 is a plan view of FIG. 5, and FIG. FIG. 8 is a perspective view of a feeder trough, and FIG. 8 is a longitudinal sectional view of a conventional tablet feeder for a tablet bucket lifter.

  The tablet charging device of the tablet bucket lifter of the present invention will be described in detail based on the drawings shown above.

  In FIG. 1, the bucket lifter 1 is disposed in the final step of the production and inspection line for a pharmaceutical tablet, and the tablet charging device 3 is disposed on one side of the lower end of the tower 2 erected on the floor surface or the like. A discharge chute 4 is provided on the other side of the upper end of the tower 2, and the tablet charging device 3 is disposed adjacent to a tableting machine which is a previous process.

  The bucket 6 is supported by the rotating shaft 7 and moves up and down along the tower 2.

  An electromagnetic linear feeder 8 is disposed adjacent to the lower part of the tower 2, and a linear feeder trough 9 is provided above the electromagnetic linear feeder 8.

  The tower 2 is provided with a touch panel 10 that controls the operation of the bucket 6 and the linear feeder trough 9.

  In order to minimize the number of cleaning parts, the present invention relates to an electromagnetic linear advance in a tablet lifter for a tablet lifter having a bucket 6 that moves up and down between a lowered position where tablets are loaded and a raised position where tablets are discharged. The linear feeder trough 9 is connected to and supported by the feeder 8 and transports and feeds the tablets supplied from the previous process to the bucket 6 at the lowered position, and the linear feeder trough 9 has a frequency of the electromagnetic linear feeder 8. The amount of tablets to be supplied was adjusted by controlling the amount of the tablets to be supplied to the bucket 6 tilted backward.

  In the present invention, by tilting the bucket 6 backward, the tilt guide can be eliminated, and the number of cleaning parts can be reduced.

  In addition, the present invention is for a tablet including a bucket 6 that moves up and down between a lowered position where a tablet is introduced and a raised position where the tablet is discharged in order to prevent the tablet from falling downward between the bucket and the front end of the transport trough. In the tablet lifter of the bucket lifter, a linear feeder trough 9 is provided which is connected to and supported by the electromagnetic linear feeder 8 and transports and feeds the tablets supplied from the previous step to the bucket 6 to the lowered position.
