As shown, a plurality of tablet cassettes 101 incorporating different tablets are densely arranged on the upper side, and two tablet conveyors 103 are provided at the lower side to collect the tablets discharged from the tablet cassette toward the center. .

In addition, a hopper 102 is provided below the tablet cassette 101 to collect the discharged tablets from being scattered to the outside of the tablet conveyor 103, and the tablets collected at the center by the tablet conveyor are components of the packaging means. A feed conveyor 104 is provided to feed the phosphorus hopper (not shown).

Accordingly, when tablets contained in the tablet cassette 101 are dropped onto the upper surface of the tablet conveyor 103 at a time by prescription, the tablet conveyor 103 is operated to transfer the dispensed tablets to the supply conveyor 104. When the tablet dispensed once by the operation of the supply conveyor 104 is supplied to the hopper (not shown) of the packaging means, the packaging device is to separate and package it.

However, as shown in the conventional tablet feeder, as the feed conveyor 104 is composed of a pair of pulleys and belts, when the position of the pulley is slightly out of the straight line, the belt is left, There is a possibility that the movement to the right to contact the wall surface of the hopper 102, resulting in noise and abrasion as well as detached from the pulley.

In addition, if the tension of the belt is too strong, the rod is generated in the rotation of the pulley, on the contrary, if too weak, a slip between the pulley (Slip) is generated as the smooth rotation of the belt is not made. Accordingly, there was an inconvenience in that the tension of the belt should be adjusted to an appropriate level by periodically adjusting the interval between the pulleys.

The present invention has been made to solve the above problems, an object of the present invention is to provide a tablet dispensing device for long-term drug distribution to prevent unnecessary left, right movement in the rotation process of the belt and smooth rotation.

In accordance with one aspect of the present invention, there is provided a tablet dispensing apparatus for dispensing organs, a plurality of tablet cassettes having different tablets, and at least one tablet conveyor for transporting tablets discharged from the tablet cassette to one side. In the tablet supply device, the tablet conveyor, the drive pulley is formed by a plurality of grooves in a longitudinal direction in the longitudinal direction on the outer circumferential surface is rotated by an external power, and arranged in a line with the drive pulley and the groove portion and A driven pulley having a groove having the same shape and having the same pitch, and a plurality of transfer members that are fitted one by one to have a constant tension in the groove portion of the position corresponding to each other of the driving pulley and the driven pulley.

The transfer member is configured such that adjacent outer circumferential surfaces are in close contact with each other, thereby preventing the tablet from being transported out between the transfer members.

According to the present invention having the configuration as described above, the plurality of transfer member is configured to move in the state of being inserted into the groove portion formed in the driving pulley and the driven pulley respectively, and to transport the tablet, so as not to move unnecessarily to the left / right during the operation process Therefore, unlike the prior art, noise and abrasion caused by contact with other parts such as the wall of the hopper does not occur.
