In the case of the recently developed tablet separating device (see Patent Document 5), a tablet dividing device has been developed which includes a holding mechanism for holding a tablet to be cut at a cutting position, and a cutting mechanism having a cutting position Advancing and retracting the opposing knife, and expanding and reducing the opposing gap of the opposing knife to cut the tablet; and cutting action specifying means for specifying an operation sequence of the cutting mechanism or an operation sequence of the cutting mechanism and the holding mechanism In the cutting operation defining means, when the opposing gap is reduced during the cutting of the tablet, the holding means continues to hold the tablet until the opposing blade holds the tablet, and the opposing blade is held. After the tablet, the tablet holding by the holding mechanism is released, and the tablet is held only by the opposing blade, and after the tablet holding by the holding mechanism is released, the opposing blade is cut into the ingot. Agent.

In the tablet dividing device (see the effect column of Patent Document 5), since the tablet is separated from the holding mechanism when the tablet is cut into the blade at the time of cutting the tablet, even if the tablet is opposed The cutting edge is deformed or displaced, and the holding mechanism does not generate a reaction force in the tablet due to the change.

In this way, due to improvements, there will be no changes in the cause and change of the state of the cutting. The increase in the amount thus causes a reaction force from the holding mechanism, so that the division is stabilized, and the variation of the amount of the tablet cutting piece becomes smaller.

Further, (see Patent Document 6), a tablet dividing device has been developed which has a purpose of reducing the burden of adjusting various kinds of tablets suitable for various shapes in order to improve the accuracy of division. The tablet guiding member forms a groove-shaped tablet dropping path from the upper end to the lower end, and the receiving member opens and closes the tablet falling on the tablet dropping path to temporarily hold the tablet dropping path a cutting position on the way; and a cutting mechanism that cuts the tablet at the cutting position; the tablet dividing device further includes: a groove depth defining member covering a portion of the tablet dropping path that is upstream of the cutting position; thickness An adjustment mechanism that expands a relative distance between a groove bottom of the tablet drop path and a groove bottom opposing surface of the groove depth defining member; and a control device that operates the thickness adjustment mechanism by obtaining thickness information of the tablet The aforementioned relative distance is adapted to the thickness of the aforementioned tablet.

In the tablet dividing device (see the effect column of Patent Document 6), the thickness information of the smallest size in the shape information of the tablet is given to the control device, and then the control device, the thickness adjusting mechanism, and the groove defining member are common. The automatic distance between the bottom of the groove of the tablet drop path and the groove bottom opposite surface of the groove depth defining member is suitable for the thickness of the tablet, thereby reducing the burden of adjustment for various kinds of tablets having different thicknesses. . Further, (refer to the embodiment of Patent Document 6), in the tablet dividing device, the falling tablet guiding member is constituted by a plate-like body, and a tablet dropping path is formed on one side thereof, and the cutting mechanism is Cutting the blade forward and backward toward the cutting position, thereby cutting the ingot Agent.

Here, it will be described that the tablet separating device is returned to the tablet cutting dust separating mechanism to suck the discharging mechanism to remove the unnecessary half ingot or the small piece generated by the cutting or the like, or to clean the tablet through the path or the device (refer to the patent document) 1, 2). In addition, the cutting mechanism reduces the amount of dust generated when the tablet is cut by the facing blade or the rotating blade (refer to Patent Documents 3, 4, and 5), and the relay portion including the collecting guide or the buffering buffer. Between the holding mechanism of the tablet or the holder of the tablet and the receptacle of the tablet cutting piece, generation of dust is prevented when the tablet cutting piece is moved (refer to Patent Document 6); since the cutting powder is not completely eliminated, the dust is not completely eliminated. The above-mentioned suction and discharge mechanism picks up the tablet to cut off the dust, or sieves the tablet with the sieve disposed in the relay portion, or cuts the dust from the tablet cutting piece to cut the dust separation mechanism. Indispensable.

However, in such a conventional tablet cutting dust separating mechanism, the separation performance is good in the case of the suction and discharge mechanism, but the component cost and the running cost are also high, and if it is not a perfect environment such as an exhaust gas treatment device, Not easy to use. On the other hand, from the viewpoint that the sieve does not have the above limitation and is simple and inexpensive, it is easy to use, but it cannot be a device that can be satisfied by a general use method. For example, when the inclined guide is made of a sieve so that it slides down on its own weight, if the inclination is too gentle, the tablet cutting piece does not fall. On the other hand, if the inclination is too steep, the tablet cutting dust is not Screening out, it is difficult to find a compromise point. In addition, when the buffer for buffering is sieved to reverse the screen upside down, if the reversal speed is increased, the tablet cutting piece and the tablet cutting dust will fly to other places, so that it is difficult to speed up. And the efficiency will not increase.

Therefore, an object of the present invention is to realize a high-efficiency tablet cutting dust separating mechanism even in the case of a screen type.

The tablet cutting dust separating mechanism (solution 1) of the present invention is a creator for solving the above problems, and includes a tablet dropping path switching member, and a plurality of through-hole shapes through which the tablet cutting piece passes are formed. The tablet falls down the path, and the above-mentioned tablet dropping path is switched by the rotation of the shaft; the partition plate is formed with a through-hole which is not cut by the tablet cutting piece but is cut by the tablet which is smaller than the cutting piece a plurality of dust separating holes; and a supporting member formed with a dust dropping path for cutting the dust of the tablet, and holding the partition plate in a state in which the partition plate covers an end surface of the dust dropping path And any one of the aforementioned tablet dropping paths comes over the aforementioned partitioning plate, and the other is in a state of being detached from the aforementioned partitioning plate and the rotating shaft is opposite to the aforementioned partitioning plate itself or the aforementioned dividing plate The tablet dropping path switching member is held in a state where the extending body is vertical, and the tablet dropping path comes to the partition plate in accordance with the axis rotation of the tablet falling path switching member. When, with the lower end face of the partition panel cover, when removed from the separator plate, i.e. the lower open end.

Further, the tablet cutting dust separating mechanism (solution 2) of the present invention is the tablet cutting dust separating mechanism of the above-described solution 1, wherein the supporting member holds the tablet dropping path switching member and the aforementioned portion in an inclined state. The inclined support member of the partition plate sets the inclined state, and the aforementioned drop path of the tablet follows the axis of the above-mentioned tablet drop path switching member When the rotation comes to the partition plate, the height is lowered, and when it is separated from the partition plate, the height is raised.

Further, the tablet cutting dust separating mechanism (solution 3) of the present invention is the tablet cutting dust separating mechanism of the above-mentioned solving means 1 and 2, wherein the tablet is used to accommodate the above-mentioned tablet falling through the dust dropping path to cut dust. The first dust collecting container is disposed below the dust dropping path; and the bottom portion is provided with a cutting piece receiving container that does not supply the tablet cutting piece but passes the member that cuts the small piece of the cutting piece to cut the dust. a drop destination of the tablet cutting piece that has fallen from the partition plate in the dropping path of the tablet; and the first tablet for cutting the dust that has fallen through the bottom of the cutting piece container 2 The dust collecting container is disposed below the cutting piece receiving container.

The above-described tablet cutting dust separating mechanism (solution 1) of the present invention is provided below/downstream of the tablet cutting position of the holding mechanism and the cutting mechanism. Specifically, although a tablet cutting dust separating mechanism is provided at a portion where the tablet cutting piece can be obtained by dividing the tablet in the tablet cutting position, the setting conditions and the like are set in particular, so that the tablet falls. The separator on the separator in the tablet drop path of the path switching member accepts the tablet cutting piece. Further, the tablet drop path switching member intermittently rotates in the axis, and when the tablet drop path switching member performs the shaft rotation, since the rotary shaft is perpendicular to the partition plate, the tablet falls on the lower surface of the path switching member, and even the drop path of the tablet The lower end surface moves in such a manner as to rub against the upper surface of the partition plate, and each time the rotation is performed, the drop path of the tablet which comes to the partition plate is switched, and Further, the tablet cutting piece which is dropped onto the partitioning path to the tablet dropping path is dropped by the tablet falling path switching member moving over the partitioning plate.

Thus, by making the tablet cutting piece forcedly moved to the partition plate by an external force, even if the posture of the partition plate becomes gently inclined or horizontal, the tablet cutting piece does not slip on the partition plate due to its own weight. In the above state, the tablet cutting piece will also smoothly roll or rub on the partition plate while moving on the partition plate, in the process, the tablet cutting dust will be separated from the dust separating hole of the partition plate. Fall and separate. Therefore, the tablet cutting dust can be surely sieved from the tablet cutting piece regardless of the inclination of the separation plate.

Moreover, the relative movement of the tablet drop path switching member and the partition plate is such as rubbing the mover, whereby the lower end face of the tablet drop path is opened as the slide door is opened, and the tablet cut piece is dropped, so that the full member is inverted The turning or lower end face is different if the sill is opened, and even if the switching speed of the drop path is increased, the falling state of the tablet cutting piece is stabilized, and the drop destination is moderately concentrated.

Therefore, according to the present invention, it is possible to realize a tablet cutting dust separating mechanism which is excellent in efficiency even for a screen type.

Further, in the tablet cutting dust separating mechanism (solution 2) of the present invention, when the tablet cutting piece is moved over the partitioning plate, the tilting direction is reversed toward the inclined surface. Therefore, the lozenge attached to the tablet cutting piece is efficiently sifted and moved to the partitioning plate, and the tablet cutting dust on the partitioning plate is switched by the dropping path of the tablet which is pushed up from below. The tablet of the member falls down the peripheral wall of the lower end portion and is efficiently dropped into the dust separating hole by, for example, being ground or pushed in, and is dropped from the tablet cutting piece.

Therefore, according to the present invention, it is possible to realize a tablet cutting dust separating mechanism which is more efficient even in the case of a screen type.

Further, in the tablet cutting dust separating mechanism (solution 3) of the present invention, it is possible to easily and surely collect the tablet cutting by providing another first dust container at a portion different from the cutting piece container. The tablet cutting piece and the tablet separated by the dust separating mechanism cut the dust. Further, when the bottom of the cutting piece container is provided with a sieve function, the second dust collecting container different from the cutting piece receiving container is disposed under the cutting piece receiving container, and the cutting can be easily and surely collected from the passing of the tablet. The lozenge produced by the tablet cutting piece after the dust separating mechanism cuts the dust.

The specific embodiment of the present invention will be described with reference to the following Example 1 in view of the above-described tablet cutting dust separating mechanism of the present invention. The first embodiment shown in Figs. 1 to 3 is a specific embodiment of the above-described solving means 1 to 3 (parts 1 to 3 of the patent application scope at the time of filing).

In addition, in the case of the simplification, etc., a fixing device such as a bolt, a connecting device such as a hinge, a driving source such as an electric motor, a transmission member such as a timing belt, a motor driver, and the like are omitted. The details of the electronic circuit such as the device are shown as the center of the invention or the related person.

Further, the tablet cassette 21 is detachably attached to the tablet supply base portion 27, and the first dust container 61 is inserted into the main body portion 24 in a state where the back surface opening is freely pulled out from the bottom of the main body portion 24, The second dust collecting container 62 and the cutting piece receiving container 63 are placed on the second dust collecting container 62 in the cutting piece receiving container 63, and the lower side portion of the cutting piece receiving container 63 is opened from the upper surface of the second dust collecting container 62. In the state in which the two stages of the second dust container 62 are overlapped, the body portion 24 is inserted in a state in which the front surface of the main body portion 24 is freely pulled out.

The main body portion 24 (see Fig. 1(b)) fixes the tablet supply base portion 27 The support member 28 is fixedly disposed in a vertical posture in the front-rear direction central portion in the casing, and a tablet having a relay portion is fixedly disposed in front of the lower portion of the support member 28 in the casing. The dust separating mechanism 50 is cut, and the cutting piece receiving container 63 and the second dust collecting container 62 are disposed on the lower side of the lower side in a state where the frame body can be moved in and out from the front side, and the lower side of the lower side of the tablet cutting dust separating mechanism 50 is disposed. The first dust container 61 is placed in a state in which it can be moved in and out from the casing.

Further, in the central portion of the casing of the main body portion 24, the holding mechanism 30, the cutting mechanism 40, and the tablet cutting dust separating mechanism 50 are attached to the supporting member 28 or other supporting members.

The tablet supply base portion 27 and the tablet cassette 21 attached to the tablet supply base portion 27 (see FIGS. 1(a) and (b)) automatically carry out the successive supply of the tablets, and the control device 23 is used. Control, the tablet is discharged from the tablet cassette 21 in one spindle, and the tablet is fed from the upper end to the holding mechanism 30. Although the holding mechanism 30 is not shown in detail, the receiving member temporarily holds the tablet of the divided object dropped from the tablet cassette 21 at the cutting position, and the cutting mechanism 40 also omits detailed illustration. However, the tablet at the cutting position is cut by a single blade or a cutter such as a counter knife or a rotary blade, and is divided into two tablet cutting pieces 11, 11.

The tablet cutting dust separating mechanism 50 functions as a relay portion that receives the tablet cutting piece 11 dropped from the lower end of the holding member 30 and feeds it into the cutting piece container 63, and performs the transfer of the tablet cutting piece 11 At this time, the undesired tablet cutting dust 12 which is smaller than the desired tablet cutting piece 11 is also separated from the tablet cutting piece 11 and sent to the first dust container 61. The role. Therefore, the tablet cutting dust separating mechanism 50 (see FIGS. 1(b) to (e)) includes a tablet dropping path switching member 51, a partition plate 52, a tilt supporting member 53, and a chute 54. And a rotary drive mechanism 55.

The tablet dropping path switching member 51 is integrally formed of a polygonal plate shape close to a rotating plate of a thick plate, and has a rotating shaft fitting hole 51b formed in the center, and is configured to sandwich the rotating shaft fitting hole 51b. Two lozenge dropping paths 51a are formed by dividing into two sides. When the tablet drop path switching member 51 is regarded as a plate-like body and is horizontally oriented, the tablet dropping path 51a and the rotating shaft fitting hole 51b are formed by vertically penetrating from top to bottom. The vertical hole shape is formed, and the upper and lower end faces are opened, but the inner peripheral surface is present on the side peripheral surface. Further, the plurality of tablet dropping paths 51a have a larger cross section than the tablet cutting piece 11 and can smoothly pass through the tablet cutting piece 11, but are narrower than the upper surface of the partitioning plate 52 and can be covered by the partitioning plate 52. End face. Further, the two tablet dropping paths 51a are formed at portions where the tablet dropping path switching members 51 are alternately switched each time the 180° axis is rotated.

The partitioning plate 52 is formed by perforating a plurality of dust separating holes 52a in the flat plate, and the dust separating holes 52a are thin longitudinal holes which penetrate the plate body when the plate body is in the lateral direction, although it is smaller than the tablet cutting piece 11 The tablet cutting dust 12 passes, but it cannot be passed through the tablet cutting piece 11 which is larger than the tablet cutting dust.

The chute 54 is constituted by a guide member such as a slide or an eaves drain pipe, and is disposed obliquely to slide the tablet cut piece 11 to be guided to the lower cut piece receiving container 63.

The rotary drive mechanism 55 is driven by the control of the control device 23 The motor of the rotating shaft, the reduction gear, and the like are configured such that the front end portion of the rotating shaft is inserted into the tablet dropping path 51a of the tablet drop path switching member 51, and the tablet dropping path switching member 51 is axially rotated.

The tilt supporting member 53 holds the above-described pieces of the tablet drop path switching member 51, the partitioning plate 52, and the chute 54 so that the lower side portion is close to the front and the upper side portion is inclined rearward by several degrees to several tens of degrees. It is fixed in the main body portion 24 (see FIGS. 1(b) and 1(d)). The inclined support member 53 (see FIGS. 1(b) to 1(e)) is formed with a dust dropping path 53a having a cross section substantially the same as or larger than the tablet dropping path 51a at a position close to the rear side. Further, a rotating shaft insertion hole 53b which serves as a bearing and which is pivotally supported by the rotation shaft of the tablet drop path switching member 51 from the rotation drive mechanism 55 is formed in a portion close to the front side. The dust dropping path 53a and the rotating shaft insertion hole 53b are formed in a vertical through vertical hole shape in a state before being inclined to the inclined supporting member 53, so that the rearward inclination is the same angle as the inclined supporting member 53. Further, the rotation axis that passes through the rotation shaft insertion hole 53b is perpendicular to the front extension plate of the partition plate 52.

The partitioning plate 52 is attached to cover the upper end surface of the dust dropping path 53a with respect to the inclined supporting member 53, so that the dust dropping path 53a is an ingot which is dropped from the partitioning plate 52 through the dust separating hole 52a. The agent cuts the dust 12 through and makes it fall more. Further, since the tablet dropping path switching member 51 is coupled to the upper end portion of the rotating shaft that is inserted into the rotating shaft insertion hole 53b, the portion of the tablet falling path switching member 51 that is wound to the rear side comes to the partitioning plate 52. Above. And, the tablet drops the path switching member 51, the ingot The agent dropping path 51a, the partitioning plate 52, and the dust separating hole 52a are inclined at the same angle as the inclined supporting member 53 with the lower side portion being close to the front and the upper side portion being inclined toward the rear.

Further, at the front end of the inclined support member 53, the upper end of the chute 54 is coupled, and the chute 54 is under the front low rear high posture in which the steep inclination is taken, and the inclined support member 53 is only extended forward to the rotating shaft. The insertion hole 53b is slightly forward, and the front end of the inclined support member 53 is located slightly forward of the rotary shaft insertion hole 53b, and thus is formed in the two tablet drop paths 51a of the tablet drop path switching member 51. When the spindle is rotated to the front of the path switching member 51 to rotate to the front, the height is raised in accordance with the inclined state of the tilt supporting member 53, and the detachment from the partitioning plate 52 is also released from the inclined supporting member 53, and in the chute. The lower end surface is opened at the upper side of the slanting support member 53 in accordance with the tilting state of the slanting support member 53, and the lower end surface is opened in the above-described tablet drop path 51a. It comes to the partitioning plate 52 and covers the upper end surface by the partitioning plate 52.

The first dust container 61 is a container formed of a plate-shaped body that is stabilized at the bottom or a box-shaped body that is open on the upper surface, and is inserted under the dust removing path 53a of the inclined supporting member 53 when being inserted into the main body portion 24, The tablet 12 that has fallen through the dust dropping path 53a is cut from the open top to cut the dust 12 and is housed therein.

The second dust container 62 is also a container made up of a plate-shaped body that is stable at the bottom or a box-shaped body that is open on the top, and is also detachably inserted into the outer box of the cutting-piece container 63, when the cutting piece is closed. 63 contained in the first 2, when the dust container 62 is disposed, the lower surface of the bottom portion of the cutting piece container 63 is located slightly higher than the inner bottom surface of the second dust container 62, and it is ensured between the bottoms to accommodate the tablet to cut the dust 12 gap.

The cutting piece container 63 is a container formed of a plate-shaped body in which a net is opened at the bottom 63a or a box-shaped body which is opened on the bottom, and the bottom net 63a is a net having a fine mesh which is not cut by a tablet. The sheet 11 passes through but the smaller amount of the tablet cutting piece 11 cuts the dust 12 through. Further, when the cutting piece container 63 is inserted into the main body portion 24 in the second dust container 62, the cutting piece container 63 is positioned below the chute 54, and the cutting piece container 63 is opened from the opening. The tablet cutting piece 11 that has been slid down on the chute 54 is received and received therein, and the second dust container 62 is housed together with the tablet cutting piece 11 into the cutting piece container 6 but does not stay in the cutting. The tablet 12 is cut into the container 63 and passed through the bottom net 63a and dropped into a tablet to cut the dust 12.

The control device 23 is omitted from the detailed illustration (see FIG. 1(b)), which is an electronic control device composed of, for example, a programmable microprocessor system or a sequencer, and the tablet is supplied to the base 27. The holding mechanism 30, the cutting mechanism 40, and the tablet cutting dust separating mechanism 50 work together to perform the operation control of each electric motor or the like, and the tablet cutting piece and the tablet are surely carried out in addition to the sequential supply and cutting of the tablet. Cut off the separation of dust.

The tablet separating dust separating mechanism 50 of the first embodiment and the tablet dividing device 20 incorporating the tablet cutting dust separating mechanism 50 will be described with reference to the drawings. Fig. 2 (a) to (d) are both the tablet cutting dust separating mechanism 50 and the receiver 61 as its expanding portion to 63 (the first dust container 61, the second dust container 62, and the cutting piece container 63) are right side views, and the operation state of the tablet cutting dust separation mechanism 50 is displayed in a time series. Further, Fig. 3 shows a state in which the tablet cutting piece 11 or the tablet cutting dust 12 is taken out, (a) is a right side view of the tablet dividing device 20, and (b) is an external perspective view of the receivers 61 to 63.

Before the tablet cutting, the tablet cassette 21 containing the plurality of tablets 10 for cutting the divided object is attached to the tablet supply base 27, and the first dust container 61 is inserted into the main body portion 24 from the rear. Further, the second dust container 62 in which the cutting piece container 63 is superposed is inserted into the main body portion 24 from the front side (see FIGS. 1(a) and 1(b)). When the tablet dividing device 20 is operated by the power supply or the like, when the operation unit 22 is operated and the tablet dividing device 20 starts the cutting process, the driving motor of the tablet supply base 27 operates and is driven by the driving motor. The tablet cassette 21 causes a tablet to fall and discharge. Further, the tablet is dropped into the main body portion 24, and is temporarily placed in the cutting position by the holding mechanism 30, and is cut by the cutting mechanism 40 to be divided into two tablet cutting pieces 11, 11.

Then, the tablet cutting pieces 11 are released from the cutting position, and are dropped toward the tablet cutting dust separating mechanism 50 (see Fig. 2(a)), and a plurality of tablets entering the tablet dropping path switching member 51 are dropped. The path 51a is wound around the rear side and reaches the tablet dropping path 51a on the partitioning plate 52 (refer to Fig. 2(b)). At this time, the tablet cutting piece 11 collides with the partitioning plate 52 to be prevented from being on the partitioning plate, so that the small tablet cutting dust 12 is dropped or fallen together with the tablet cutting piece 11, or is colliding. When it is separated from the tablet cutting piece 11 and scattered, most of them are dropped by the dust separating hole 52a and are accommodated. The first dust container 61 (see the dotted line in Fig. 2(b)).

Then, the tablet drop path switching member 51 rotates in the axis, and with the rotation, the tablet drop path 51a on the rear side advances while drawing an arc shape (refer to Fig. 2(c)), and the tablet cutting piece 11 is edged. The inclined surface of the partitioning plate 52 is pushed up, and at this time, the tablet cutting piece 11 is rubbed against the upper surface of the partitioning plate 52, and the tablet cutting dust 12 attached to the tablet cutting piece 11 is sieved to separate. The tablet cutting dust 12 above the plate 52 and waiting between the dust separating holes 52a and the like on the partitioning plate 52 is pressed by the inner peripheral wall of the lower end portion of the tablet falling path switching member 51 or When it is moved to the dust separation hole 52a, it is moved by the dust separation hole 52a, and is accommodated in the first dust collection container 61 (see the dotted line in Fig. 2(c)).

Then, when the tablet dropping path 51a that has been placed to receive the tablet cutting piece 11 comes forward of the front end of the tilt supporting member 53, (see FIG. 2(d)), the ingot conveyed by the tablet dropping path 51a The agent cutting blade 11 is detached from the partitioning plate 52 or the inclined support member 53, and falls from the lower end surface of the open tablet dropping path 51a, and is guided into the cutting piece container 63 by the chute 54. The tablet cutting piece 11 received by the cutting piece receiving container 63 is larger than the mesh of the bottom net 63a, and therefore stays on the bottom net 63a and is accommodated in the tablet cutting piece 11, but when the tablet cutting piece 11 slides down The tablet cutting dust 12 separated from the tablet cutting piece 11 when it is over the chute 54 or when flying into the cutting piece container 63 is dropped through the bottom net 63a and is housed under the cutting piece container 63. The second dust container 62 (see the dotted line in Fig. 2(c)).

Thus, the tablet cutting piece 11 which is dropped from the cutting position and comes to the tablet cutting dust separating mechanism 50 is housed in the cutting piece container 63, and at this time, in the portion where the tablet cutting dust separating mechanism 50, the tablet cuts the dust. 12 is separated from the tablet cutting piece 11 and stored in the first dust container 61, and at the portion of the cutting piece container 63, the tablet cutting dust 12 is separated from the tablet cutting piece 11 and stored in the second dust container. 62, so most of the tablet cutting dust 12 will separate the containment.

Further, while the tablet dropping path 51a for cutting the dust 12 is advanced, the empty tablet dropping path 51a is retracted and the two are interchanged, so that the next tablet cutting piece 11 can be quickly received in the ingot. Since the dust separating means 50 is cut (see Fig. 2 (d)), the cutting of the tablet can be efficiently repeated in a short cycle.

Then, after the required number of the tablet cutting pieces 11 are formed (refer to Fig. 3 (a)), the first dust container 61 is pulled out from the main body portion 24, and the second dust is collected from the main body portion 24. The container 62 is pulled forward, and the cutting piece receiving container 63 is pulled upward from the second dust collecting container 62.

Then, (see Fig. 3(b)), substantially only the tablet cutting piece 11 remains in the cutting piece container 63, and almost all of the tablet cutting dust 12 is separated from the tablet cutting piece 11 and stored in the first The dust collection container 61 and the second dust collection container 62.

(other)

Further, in the above-described embodiment, the presence or absence of the detection sensor for detecting the tablet or the tablet cutting blade 11 is not described, but it may be disposed in the portion where the tablet or the tablet cutting blade 11 passes. Whether there is a tablet with or without detection To detect whether the tablet or tablet cutting piece 11 is normally dropped. The presence or absence of the detection sensor of the tablet is easy to use the non-contact photo sensor, and can be set, for example, (see Fig. 3(a)) the tablet passing point of the tablet supply base 27, the lozenge of the holding mechanism 30. The point 72, the vicinity of the tablet cutting position 73 of the cutting mechanism 40, the tablet receiving portion 74 of the tablet cutting dust separating mechanism 50, the tablet releasing portion 75 of the tablet cutting dust separating mechanism 50, and the like are appropriately formed.

In the above-described embodiment, the tablet drop path switching member 51 is pivoted about the rotation axis fitting hole 51b. However, the specific rotation state is not described. Therefore, the tablet drop path will be additionally described here. Although the shaft rotation of the switching member 51 can be continuously rotated at a constant speed, it is possible to prevent the spindle cutting piece 11 from rotating when the tablet cutting piece 11 is not dropped, and to detect the presence or absence of the above-described tablet. When it is output to confirm that the tablet cutting piece 11 normally cuts the tablet receiving portion 74 of the dust separating mechanism 50 by the tablet, the rotation is started after waiting for the predetermined delay time.

In this case, the appropriate value of the delay time is the time until the tablet cutting piece 11 which has fallen from the holding mechanism 30 and enters the tablet dropping path 51a is stabilized on the partition plate 52 and becomes stable. . In this way, the following effects can be more reliably achieved: the tablet cutting dust 12 from the process of rolling the tablet cutting piece 11 on the side of the partitioning plate 52 or rubbing against the partitioning plate 52. The basic effect of the dust separation hole 52a falling and separating; and the lozenge cutting attached to the tablet cutting piece 11 since the tablet cutting piece 11 is moved obliquely toward the upper side of the inclined surface when moving over the partitioning plate 52 Dust 12 is effectively screened and moved to The effect of the further layer above the partition plate 52.

Further, in the above-described embodiment, the two tablet dropping paths 51a are formed only in the tablet dropping path switching member 51, but the tablet dropping path 51a is not limited to two, and may be three or more. For example, the tablet dropping path switching member 51 is formed with four tablet dropping paths 51a, and initially receives the tablet cutting pieces at the first and second tablet dropping paths 51a wound around the partitioning plate 52. 11. The tablet dropping path switching member 51 is then intermittently rotated by 180° each time, and the following processing is alternately repeated each time: the tablet cutting piece 11 is discharged from the first and second tablet dropping paths 51a, And the tablet cutting piece 11 is received in the third and fourth tablet dropping paths 51a, and the tablet cutting piece 11 is discharged from the third and fourth tablet dropping paths 51a, and in the first and second The tablet dropping path 51a receives the tablet cutting blade 11.

Further, for example, the tablet dropping path switching member 51 is formed with five tablet dropping paths 51a, initially receiving the tablet cutting piece 11 at the first tablet dropping path 51a wound up to the partitioning plate 52, and then The tablet dropping path switching member 51 is intermittently rotated by 144° each time, and the following processes are alternately repeated each time: the tablet cutting piece 11 is discharged from the first tablet dropping path 51a, and the third tablet is discharged. The dropping path 51a receives the tablet cutting piece 11, and discharges the tablet cutting piece 11 from the third tablet dropping path 51a, and receives the tablet cutting piece 11 in the fifth tablet dropping path 51a, from the fifth tablet The dropping path 51a discharges the tablet cutting piece 11, and receives the tablet cutting piece 11 in the second tablet dropping path 51a, and discharges the tablet cutting piece 11 from the second tablet dropping path 51a, and in the fourth ingot Agent falling down The diameter 51a receives the tablet cutting piece 11, and the tablet cutting piece 11 is discharged from the fourth tablet dropping path 51a, and the tablet cutting piece 11 is received in the first tablet dropping path 51a.

Further, in the above embodiment, although the tablet is equally divided into two tablet cutting pieces, it may be divided into three or more tablet cutting pieces or unevenly divided.

Further, it is not necessary for the tablet dividing mechanism 20 to be provided in the operation portion 22 of the tablet dividing mechanism 20 in the above embodiment. For example, a series of operations may be started depending on the situation after the tablet is loaded. If the automatic sequential supply of the tablet is not required, the tablet supply base 27 or the tablet cassette 21 is not required.
