Here, a nozzle 411 having a downward discharge type structure so as to discharge air into the inlet of the pouch 1 located at a lower side thereof is preferable.
In addition, as shown in FIGS. 2 and 3, the relay unit 42 further includes a collection hopper 424 for collecting the dropped pills, which pass from the bottom transfer plate 222 of the top transfer part 20 to the pill input pipe 31, to guide the collected pills to move to the relay hopper 421.
Moreover, as shown in FIGS. 2 and 3, the plate drive unit 423 of the relay unit 42 includes a supporting bar 423 a provided at an upper portion of a front side of the relay hopper 421; a known pneumatic cylinder 423 b provided with a cylinder body 423 b 1 and a piston 423 b 2 installed therein, which are hinge-coupled to the supporting bar 423 a, and enabling the piston 423 b 2 to perform a forward and backward movement according to a selective supply of air; a first hinge 423 c mutually connecting an end of the piston 423 b 2 of the pneumatic cylinder 423 b and a middle end of a front surface of the shutter plate 422; and a second hinge 423 d mutually connecting an upper portion of the shutter plate 422 and a lower portion of the front side of the relay hopper 421.
With such a configuration, opening and closing operations of the shutter plate 422 may be possible based on the second hinge 423 d by the forward and backward movement of the piston 423 b 2 of the pneumatic cylinder 423 b. At this point, a lower portion surface of the outlet of the relay hopper 421 has a structure which is inclined from the front side more as it nears the rear side, and the shutter plate 422 has a size capable of blocking the outlet of the relay hopper 421. When the pills are input into the inlet of the pouch 1, the shutter plate 422, which is rotated to be opened by the plate drive unit 423, having a rotational angle so as to support an inward side of the inlet of the pouch 1 toward an outward direction thereof may be preferable.
As a result, the opened outlet of the pouch 1 may be supported by the shutter plate 422, which is rotated to be opened, to maintain an open state.
In addition, as shown in FIGS. 2, 3, and 5, the sealing unit 43 includes two guide poles 431 longitudinally and horizontally disposed at both ends of the front surface of the front cover 114 of the bottom body 11; a sealing body 432 inserted into the two guide poles 431; the heating bar 433 provided horizontally on a rear surface of the sealing body 432; and a sealing drive unit 434 for moving the sealing body 432 forward and backward along the two guide poles 431, and which is controlled by the controller 33. At this point, the sealing drive unit 434 is fixed to and installed at the horizontal frame 113 of the bottom body 11 and an end of the built-in piston 423 b 2 is connected to the sealing body 432, wherein the sealing drive unit 434 may be connected to the sealing body 432 without interfering with the pouch 1 into which the pills are input, and may include a known pneumatic cylinder capable of moving the sealing body 432 in forward and backward directions according to a selective supply of air. Therefore, the sealing drive unit 434 may be modified and changed in a variety of forms within the range satisfying conditions for moving the sealing body 432 in forward and backward directions.
As a result, when the inputting of the pills into the inlet of the pouch 1 is completed, the heating bar 433 positioned at the rear surface of the sealing body 432, which is advanced by the sealing drive unit 434, heats and seals the inlet of the pouch 1.
In addition, the packing part 40 further includes a guide unit 44 pushing both ends of the inward side of the inlet of the pouch 1 to induce a closing of the inlet of the pouch 1 when being sealed by the sealing unit 43 after the inputting of the pills into the inlet of the pouch 1 is completed. As shown in FIGS. 4 and 5, the guide unit 44 includes a guide cylinder 441 of a pneumatic cylinder structure provided at one side of the upper transfer roller 13 in the front cover 114 of the bottom body 11; a guide piston 442 installed in the guide cylinder 441 and performing a reciprocating movement in left and right directions according to a selective supply of air; a guide pushrod 443 of a backslash ‘\’ shape hinge-coupled to an end of the guide piston 442 and having a long hole formed at a middle portion of the guide pushrod 443 in a length direction; and a guide pin 444 provided at the guide cylinder 441 and fitted in the long hole of the guide pushrod 443. With such a configuration, when the guide piston 442 advances, the guide pushrod 443 simultaneously advances with the advancing of the guide piston 442 to perform a rotational operation based on the guide pin 444. At this point, the guide pushrod 443 being vertically erected pushes the inward side of the inlet of the pouch 1 toward an outward direction thereof.
Moreover, a guide unit 44 is further provided at the other side of the upper transfer roller 13 in the front cover 114 of the bottom body 11, wherein the two guide units 44 are provided in a structure facing each other such that the both ends of the inward side of the inlet of the pouch 1 are pushed toward the outward direction thereof to induce a closing of the inlet of the pouch 1.
Meanwhile, when the inlet of the pouch 1 is sealed by the sealing unit 43, the upper or lower transfer roller 13 or 14 is rotated in reverse by the transfer roller drive unit 15 to separate and drop a sheet of the pouch 1 from the pouch roll when the heating bar 433 of the sealing unit 43 pressurizes and fixes the inlet of the pouch 1.
Looking at an operation of the automatic pill counting and packaging apparatus with such a configuration, pills accommodating in the main hopper 21 of the top transfer part 20 are transferred to the bottom transfer plate 222 after passing the top transfer plate 221 of the transfer plate 22; the bottom transfer plate 222 being vertically vibrated by the vibration unit 23 transfers the pills to a front side; the photo-coupler 32 counts the pills passing through the pill input pipe 31; the controller 33 controls the plate drive unit 423 based on the counted value to rotate the shutter plate 422, thereby closing the outlet of the relay hopper 421; and the controller 33 simultaneously controls the sealing drive unit 434 to move the sealing body 432 backward such that the heating bar 433 positioned at the rear side of the sealing body 432 heats and seals the inlet of the pouch 1 and simultaneously pressurizes the inlet. The controller 33 simultaneously controls the guide cylinder 441 to advance the guide piston 442 such that the guide pushrod 443 connected to the guide piston 442 is rotated based on the guide pin 444 to be vertically erected and to close the inlet of the pouch 1. At this point, a rotational operation of the guide pushrod 443 is completed before the sealing body 432 begins a backward movement operation and the heating bar 433 reaches the inlet of the pouch 1, that is, before pressurizing the inlet.
After the sealing is completed, the controller 33 controls the transfer roller drive unit 15 to rotate the upper or lower transfer roller 13 or 14 in reverse to separate the sheet of the pouch 1 from the pouch roll, and then the guide pushrod 443 and the sealing body 432 are respectively restored to their original positions. Also, the controller 33 controls the transfer roller drive unit 15 to rotate the upper or lower transfer roller 13 or 14 to provide a sheet of the pouch 1 to the front side. In addition, the controller 33 controls an air supply unit 412 to open an inlet of the pouch 1 using air discharged from the nozzle 411 at the same time as opening the outlet of the relay hopper 421 through the shutter plate 422, thereby restarting an input of the pills into a newly supplied pouch 1.
At this point, when the outlet of the relay hopper 421 is closed by the shutter plate 422, the pills supplied to the relay hopper 421, which have been counted by the counting part 30, and the controller 33 reflects the counted value of the pills when restarting the input of the pills into the newly supplied pouch 1, thereby an input of a target value of pills is performed.
In accordance with the present invention, a primary effect of the automatic pill counting and packaging apparatus may be the possibility of packaging pills in a vinyl type pouch instead of a typical vessel used in pill packing.
Also, in accordance with the present invention, when pills are packed in a pouch, each process for opening and fixing an inlet of the pouch, closing and sealing the inlet of the pouch, discharge the pouch, and the like may be automatically performed in the packing part.
Although the present invention has been described above with reference to the accompanying drawings by focusing on “the automatic pill counting and packaging apparatus” having an inventive form and structure, numerous other modifications and alternations can be devised by those skilled in the art and these should be construed as falling within the spirit and scope of the principles of the present invention.
