The terminology used herein is a term used to properly express the preferred embodiment of the present invention, which may vary depending on the intention of the user or operator or the custom in the field to which the present invention belongs. Therefore, the definitions of these terms should be based on the contents throughout this specification.

FIG. 1 is a front view showing a medicine packing paper sealing apparatus according to an embodiment of the present invention. Referring to FIG. 1, the medicine packing paper sealing apparatus 10 according to the embodiment of the present invention includes a medicine packing paper 1, (T) (see FIG. 4) is injected into the container and the container is divided into one dose and sealed. 3), a pulling roller drive motor 60, a pair of heating rollers 51, 52 (see FIG. 3), a pair of heating rollers 51, 52 (25, 35), and a heating roller drive motor (not shown).

The medicine packaging paper supply unit includes a medicine wrapping paper supply roller 11, a plurality of guide rollers 12, 13, 14, 15 and 16, and a folding guide 19. The medicament wrapping paper supply roller 11 is a roller on which the medicinal wrapper paper 1 rolled in a roll shape is mounted and releases the roll of the medicament wrapping paper 1 to continuously supply the medicament wrapping paper 1 without interruption. The plurality of guide rollers 12, 13, 14, 15 and 16 guide the path of the medicine wrapping paper 1 supplied from the medicine packing paper feed roller 11 to the folding guide 19.

The folding guide 19 guides the medicine wrapping paper 1 to the two side edges 2 (see FIG. 4) so that the two sides of the medicine wrapping paper 1 overlap each other, 25, and 35, respectively. The folding guide 19 is disposed below the final hopper 8 of the medicament supply device which dispenses the tablets prepared according to prescription and dispenses the medicines one time at a time.

2 and 3 are a front view and a left side view showing an enlarged view of a heating roller and a pulling roller of Fig. 1, Fig. 4 is a view showing the operation of the heating roller and the pulling roller of Figs. 2 and 3 And FIG. 5 is a cross-sectional view showing a portion VV in FIG. 2 to 5, first and second pulling roller shafts 53 and 54 extend along the rotation axis CL3 and CL4 of the first and second pulling rollers 51 and 52, First and second heating roller shafts 46 and 47 which are rotatably supported on the upper bracket 21 and extend along the rotation axis CL1 and CL2 of the first and second heating rollers 25 and 35, Is rotatably supported by the upper bracket 21 and the lower bracket 22.

The first and second pulling rollers 51 and 52 are rotated in close contact with each other so that the overlapping side edges 2 of the medicine wrapping paper 1 are sandwiched between the rollers 51 and 52 to form a double- The packaging paper 1 is pulled so as to proceed in the progressing direction thereof. The first and second pulling rollers 51 and 52 have the same radius of radius RP and are rotated in opposite directions interlocked by the driving force of the pulling roller driving motor 60.

 Specifically, a motor gear 58 is fixedly coupled to the rotary shaft 61 of the pulling roller drive motor 60, a gear 57 fixedly coupled to the second pulling roller shaft 54, Respectively. Another gear 56 fixedly coupled to the second pulling roller shaft 54 is engaged with a gear 55 fixedly coupled to the first pulling roller shaft 53. As a result, when the rotating shaft 61 of the pulling roller driving motor 60 rotates, the first and second pulling rollers 51 and 52 rotate in opposite directions to each other by the driving force, (1).

The first and second heating rollers 25 and 35 are disposed between the folding guide 19 and the pair of pulling rollers 51 and 52 and are interlocked by the driving force of a heating roller driving motor And rotate in opposite directions to each other. Specifically, a bevel gear (not shown) fixedly coupled to a rotating shaft (not shown) of the heating roller driving motor is engaged with a bevel gear 50 fixedly coupled to the first heating roller shaft 46. Another gear 48 fixedly coupled to the first heating roller shaft 46 is engaged with a gear 49 fixedly coupled to the second heating roller shaft 47. Accordingly, when the rotating shaft (not shown) of the heating roller driving motor rotates, the first and second heating rollers 25 and 35 rotate in opposite directions due to the driving force.

The first and second heating rollers 25 and 35 each have widthwise fusing surfaces 27 and 37, heating flanges 28 and 38, lower contact flanges 30 and 40, (31, 41). Heaters 34 and 44 linearly extended along the rotation axis lines CL1 and CL2 of the first and second heating rollers 25 and 35 are provided in the first and second heating rollers 25 and 35 Inserted. The heaters (34, 44) generate heat when power is supplied.

The width direction fusing faces 27 and 37 are formed on the connecting pillars 26 and 36 of the first and second heating rollers 25 and 35 connecting the heating flanges 28 and 38 and the lower contact flanges 30 and 40 Are provided on both sides. The heating flanges 28 and 38 are cylindrical portions connected to the upper ends of the connecting columns 26 and 36 and extending in the radial direction around the first and second heating roller axes CL1 and CL2. The pair of heating flanges 28 and 38 have the same radius RH and their outer circumferential surfaces are not in contact with each other and the gap G between the protrusions 28 and 38 is 50 to 300 占 퐉.

The lower contact flanges 30 and 40 are cylindrical portions connected to the lower ends of the connecting columns 26 and 36 and extending in the radial direction around the first and second heating roller axes CL1 and CL2 . The pair of lower contact flanges 30 and 40 have the same radius, and their outer peripheral surfaces are in contact with each other. The upper contact flanges 31 and 41 are cylindrical portions that are disposed on the upper side of the heating flanges 28 and 38 and extend in the radial direction around the first and second heating roller axes CL1 and CL2 . The pair of upper contact flanges 31 and 41 also have the same radius, and their outer peripheral surfaces are in contact with each other.

The radius of the upper contact flange 31 and the radius of the lower contact flange 30 are equal to each other and the radius RH of the heating flanges 27 and 37 is equal to the radius of the upper flange 31, 30, and 40, respectively. Since the pair of lower contact flanges 30 and 40 and the pair of upper contact flanges 31 and 41 maintain contact when the first and second heating rollers 25 and 35 rotate together with each other, 1 and the second heating roller 25, 35 are prevented from tilting.

When the heaters 34 and 44 inside the first and second heating rollers 25 and 35 generate heat, the widthwise fused surfaces 27 and 37 and the heating flanges 31 and 41 also generate heat at a high temperature by thermal conduction. When the first and second heating rollers 25 and 35 are rotated in conjunction with each other when the double wrapped medicinal wrapper 1 passes between the first and second heating rollers 25 and 35, The widthwise fusing surface 27 of the second heating roller 35 and the widthwise fusing surface 37 of the second heating roller 35 are brought into close contact with each other with the medicine wrapping paper 1 having the two ply therebetween, 1) is fused and sealed in the width direction, that is, parallel to the Z axis. The width direction fusion region 4 is formed in the medicine wrapping paper 1 every time the first and second heating rollers 25 and 35 are rotated half a turn.

A single space 3 for accommodating a single dose T of medicament T is defined by a pair of widthwise fusion regions 4 formed adjacent to the medicament wrapper 1. When the rotational speeds of the first and second pulling rollers 51 and 52 are kept constant, the gap between the adjacent pair of the widthwise welded regions 4 is larger than the gap between the first and second heating rollers 25, 35).

A pair of widthwise fused surfaces 27 of the first heating roller 25 are formed in the widthwise direction of the medicinal wrapper 1 so as to form the perforated lines 5 in the region sealed by fusion, A cutter 33 extending in the longitudinal direction of the width direction fusing surface 27 is fixedly mounted. In the embodiment shown in Figs. 1 to 4, the cutter 33 is provided only on the first heating roller 25, but the present invention is not limited thereto. For example, a cutter may be provided only on the second heating roller 35, and a cutter may be provided on both the first heating roller 25 and the second heating roller 35.

The overlapping portions of both side edges 2 of the medicinal wrapper 1 pass through the pair of heating flanges 28 and 35 when the double wrapped medicinal wrapper 1 passes between the first and second heating rollers 25 and 35. [ 38, and the gap between the both side edges 2 is broken. However, since the pair of heating flanges 28, 38 are spaced apart with a slight gap G, the portions of both side edges 2 are not in close contact with the pair of heating flanges 28, 38, Even if the rotational speeds of the pair of pulling rollers 51 and 52 and the pair of heating rollers 25 and 35 are not the same, the wrapping paper 1 is not torn or wrinkled.

The portions on both side edges 2 of the double-folded medicinal wrapper 1 pass through a space between the pair of heating flanges 28 and 38 which generate heat at high temperature, and are heated and melted adhesively. The portions of both side edges 2 are pulled at a constant speed by a pair of pulling rollers 51 and 52 and heated between a pair of heating flanges 28 and 38 for a short time. Therefore, the both side edges 2 do not melt to such an extent that they are completely liquefied and flow down.

The portions of the both side edges 2 passing between the pair of heating flanges 28 and 38 are tightly sealed with each other while passing through a pair of pulling rollers 51 and 52 which are tightly coupled to each other. As a result, the upper end portion 7 of the medicinal wrapper 1, which has passed through the pair of pulling rollers 51 and 52, is formed at its upper end and extends continuously in the longitudinal direction of the medicinal wrapper 1. In summary, the medicine wrapping paper 1 is folded in two, the medicine T is fed, and the pair of heating rollers 25 and 35 is paired with the pair of heating rollers 25 and 35 The widthwise fusion region 4 and the upper fusion region 7 are formed while passing between the pulling rollers 51 and 52. The widthwise confining region 4 and the upper fusion region 7 are formed in the filling space 3 defined by the fusion regions 4 and 7, The medicament (T) is accommodated.

If the gap G between the pair of heating flanges 28 and 38 is too narrow, the opposite side edges 2 of the medicine wrapping paper 1 pass between the pair of heating flanges 28 and 38 Due to the difference between the rotation speed of the pair of heating flanges 28 and 38 and the advancing speed of the chemical wrapping paper 1 in this state, The corner (2) portion may be torn or wrinkled. If the gap G between the pair of heating flanges 28 is too wide, the heat of the pair of heating flanges 28 and 38 is not transmitted to the both side edges 2, The portions of both side edges 2 may not be tacky. Therefore, the gap G is preferably larger than twice the thickness of the medicinal wrapper 1 and smaller than 20 times, more specifically, 50 to 300 μm.

If the distance between the pair of heating rollers 25 and 35 and the pair of pulling rollers 51 and 52 is too far apart, (2) portion is hardened again before passing between the pair of pulling rollers (51, 52), so that the tackiness is lost and the portions of both side edges (2) are not fused. Therefore, the distance between the pair of heating rollers 25 and 35 and the pair of pulling rollers 51 and 52 is set as close as possible to the rotation of the rollers 25, 35, 51 and 52, . Unlike the heating rollers 25 and 5, the pulling rollers 51 and 52 are not provided with a heater therein. In order to reduce the capacity, power consumption, and size of the pulling roller driving motor 60, It is preferable that the radius RP of the pulling rollers 51 and 52 is smaller than the radius RH of the heating rollers 25 and 35. [

The rotation centers CL1 and CL2 of one heating roller 25 and 35 adjacent to each other among the pair of heating rollers 25 and 35 and the pair of pulling rollers 51 and 52 and one pulling roller 51 The distance DT between the rotation centers CL3 and CL4 of the heating flanges 28 and 38 is larger than the sum of the radius RH of the heating flanges 28 and 38 and the radius RP of the pulling rollers 51 and 52, 38 is less than twice the radius RH of the flanges 28, 38, i.e., the diameter of the heating flanges 28, 38.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the present invention. Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
