As shown, the electric medicine supply device 10 according to this embodiment has a basic structure of an upper casing 20, a plurality of sliding modules 30, a lower casing 60, and a hopper 50. Although not shown individually in FIG. 1, elements other than the sliding module 30 and the hopper 50 are also included in the upper and lower casings 20 and 60.

The upper casing 20 and the lower casing 60 are arranged vertically and connected to form a cabinet structure as a whole. In addition, the inside of the upper casing 20 and the lower casing 60 communicate with each other so that the medicine freely falling from the upper casing 20 is lowered to the lower casing 60 and then packaged and discharged through the drug discharge port 61. .

The upper casing 20 takes a form open to the front and accommodates a plurality of sliding modules 30. The sliding module 30 has, for example, the structure of FIG. 2 or 7, and is inserted into the upper casing 20 and can slide forward and backward when necessary.

For example, it is possible to replenish medicines in a drug cassette (not shown) accommodated in the sliding module 30, or pull out the sliding module 30 in the direction of an arrow a to clean the inner circumference. The withdrawal of the sliding module 30 and the storage into the upper casing 20 are implemented by the driving unit 40 to be described with reference to FIGS. 7 and 8.

The lower casing 60 accommodates a hopper (50 in FIG. 2) and a packaging device (not shown) therein, and has a drug discharge port 61 in the front. The hopper 50 passes the medicine dropped from the sliding module 30 through the inside of the drug and delivers it to the packaging device. The packaging device packs and seals the delivered medicine once at a time and sends it out to the outside through the medicine outlet 61. The packaging device is the same as the packaging device of a general drug supply device, and a description thereof is omitted.

FIG. 2 is a view showing the sliding module shown in FIG. 1 separately. In addition, FIG. 7 is an exploded perspective view showing the sliding module viewed from a different angle.

As shown, the sliding module 30 includes a rectangular frame-shaped frame 31, a blocking wall 32 fixed to the inner region of the frame 31, and a sliding rail provided at the upper and lower ends of the frame 31 (Fig. It includes a cover (35) covering the 33) of 9 and the sliding rail (33).

First, the frame 31 is exposed to the front of the upper casing 20 and has a front plate portion 31a having a control panel 31e, a rear plate portion 31b disposed corresponding to the rear of the front plate portion 31a, and a front plate portion It consists of a plurality of crossbars (31c) fixed horizontally between the and the rear plate.

The control panel 31e disposed on the front plate portion 31a is an input/output means for displaying the inventory status of drugs currently accommodated in the drug supply device 10 as well as for the user to order withdrawal of prescription drugs. A touch panel can be applied as the control panel 31e. The user inputs the required drug withdrawal through the control panel 31e. The detailed display content, screen design, or function of the control panel 31e may be the same as that of a general drug supply device.

A plurality of crossbars 31c are disposed horizontally and provide a cassette storage space 31d for accommodating a drug cassette (not shown) at the top of each. The drug cassette is a medicine container that accommodates different kinds of medicines therein, and discharges the input amount of medicine when a medicine discharge signal is received through the control panel 31e.

The medicine discharged from the cassette passes through the medicine passage 32c to the dropping space 36a. To this end, the injection port 32a is positioned corresponding to the position where the drug cassette is installed. The inlet 32a is a passage formed by pressing the barrier wall 32. The barrier wall 32 is a stainless steel plate having a certain thickness. It goes without saying that the number of cassettes and inlets 32a is the same.

The blocking wall 32 is a plate-shaped member made of stainless steel, and divides the inner space of the frame 31 into a cassette storage space 31d and a dropping space 36a. The cassette storage space 31d is a space in which the drug cassette is located, and the dropping space 36a is a space in which the medicine passing through the medicine passage 32c falls freely and moves to the hopper 50.

Meanwhile, as shown in FIG. 2, a plurality of guide slides 38 are provided in the dropping space 36a. The guide slide 38 extends downward in the diagonal direction and serves to guide the medicine passed through the medicine passage 32c in the diagonal direction. The reason for applying the guide slide 38 is to collect the medicines in one place. That is, it is to concentrate the medicine to the lower center of the sliding module (30).

When the guide slide is extended up and down, the width of the inlet of the hopper should also be extended to the portion where the guide slide is located. However, according to the present invention, by guiding the extension slide to guide the drug to the central portion to fall, the width of the hopper inlet can be reduced.

In this way, since the width w of the inlet of the hopper 50 can be greatly reduced, the space utilization inside the lower casing 60 is improved as the size of the hopper 50 is reduced. In other words, the degree of freedom of installation of a device for packaging or printing of drugs is increased.

The guide slide 38 itself takes the form of a band having a certain width. With the door 37 closed, both ends in the width direction are in contact with the barrier wall 32 and the door 37.

In addition, a pair of hinged doors 37 are symmetrically installed on the frame 31. The door 37 rotates while being supported by the door hinge 37a to open or block the falling space 36a. For example, to open the door 37 to clean the interior of the falling space (36a). With the door 37 closed, the dropping space 36a is sealed. To this end, a sealing seal may be applied between the frame 31 and the door 37.

The sliding rails 33 are horizontally fixed to the upper and lower ends of the frame 31 and the two are parallel to each other. Each sliding rail 33 is accommodated in the support rail 34 and is slidable in the longitudinal direction of the support rail 34. The support rail 34 is fixed inside the upper casing 20. As a result, the sliding module 30 slides forward or is received in the opposite direction while being supported by the support rail 34.

The cover 35 is fixed to the upper and lower ends of the frame 31 and prevents foreign matter from penetrating between the sliding rail 33 and the support rail 34.

The guide slide 38 shown in FIG. 3 includes a swash plate portion 38a having a certain width and one side in contact with the barrier wall 32, and a guide portion 38b integrally formed with the other end of the swash plate portion 38a. Have. The guide portion 38b is a portion bent at a right angle with respect to the swash plate portion 38a and prevents the medicine moving along the swash plate portion 38a from splashing and escaping to the side.

Reference numeral 38c denotes a cushioning sheet. The buffer sheet 38c is a silicon film having a thickness of 1 mm or less and can be attached and detached. For example, if the buffer sheet contains fine powder of medicine, the buffer sheet 38c is removed, washed, and then reinstalled.

By applying the cushioning sheet in this way, the guide slide 38 can always be kept clean. For example, it is possible to prevent the drug supplied from being contaminated by the powder of the drug supplied first. In the case of babies with weak immunity or the elderly, taking drugs of other ingredients besides the prescribed drugs may cause side effects or complications, this risk is completely eliminated.

4 is a perspective view of a sliding module showing another modified example of the induction slide shown in FIG. 2, and FIGS. 5A, 5B, and 5C are plan views for explaining the operation of the induction slide shown in FIG. 4.

The motor 42 rotates the driving pulley 43a by driving according to the operation signal input through the control panel 31e. In addition, the driven pulley 43b is installed above the driving pulley 43a and is connected to the driving pulley 43a through a timing belt 43c. The diameters of the driving pulley 43a and the driven pulley 43b are the same.

In addition, the ball screw 46 is fixed to the rotating shaft of the driven pulley 43b. The ball screw 46 is installed horizontally on the upper portion of the frame 31, and both ends thereof are supported so as to be axially rotatable through bearings (no drawing marks). In addition, the ball screw 46 is engaged with the transmission block 47. The transmission block 47 is fixed to the upper end of the frame 31 and moves linearly along the longitudinal direction of the ball screw 46 according to the axial rotation of the ball screw 46.

As a result, when the motor 42 operates, the rotational force of the motor is transmitted to the sliding module 30, so that the sliding module 30 slides in the direction of arrow a in FIG. 1 or the opposite direction.

The porous disk 44 is a disk-shaped member fixed to the driving shaft of the motor 42 together with the driving pulley 43a, and serves to detect the rotational speed of the driving pulley 43a, that is, the total rotation angle.
