Tablet sorting device

The present invention relates to a tablet dividing device for cutting a tablet into a plurality of tablet cut pieces by cutting the tablet.

The tableting device for dividing the tablet into two tablets is practical except for the conventional tablet separating machine which cuts the tablet into a tablet and ingots and cuts the tablet. In addition, the tablet in the drop path of the tablet is divided into two parts in the direction of the passing direction and then the tablet is cut by cutting the tablet drop path (the path of the tablet through the path). When the cut pieces are discharged one by one, the tablets which are stored/held in one spindle can be automatically supplied to the tablet supply device such as the subsequent packaging device in units of less than one spindle (see, for example, Patent Document 1); And cutting the received tablet into upper and lower portions by the blade of the cutter, and discharging the lower tablet cutting piece first, and temporarily placing the upper tablet cutting piece on the tool to the next tool. The tablet supply device that is discharged one step at a time (see, for example, Patent Document 2).

The conventional apparatus as described above is incorporated in or below the tablet storage of the tablet dispensing machine, and the one blade provided in the cutting mechanism is cut into the divided object held by the holding mechanism at the cutting position. Lozenges.

Further, the conventional tablet separating device is used for guiding a tablet from an external tablet feeder or the like to a duct of a tablet dividing device, and additionally in a tablet dividing device. The hollowing out forms a lozenge drop path (the lozenge passage path) that vertically penetrates into a vertical hole shape, so that the tablet is approached from the path The state of natural fall falls straight down directly below.

If attention is paid to the cutting mechanism, a tablet dividing device having two blades for cutting the cutting mechanism has been developed. In the tablet separating device, the tablet is divided into a plurality of tablet cutting devices by cutting a tablet with a cutting mechanism having a straight blade, and the blade is set to two. In the state in which the sheets are opposed to each other, the cutting mechanism is configured such that the opposing gaps are enlarged and reduced while the two opposing cutting edges are held in parallel, and the tablet is cut while expanding and reducing the opposing gaps. The two blades are interlaced in parallel directions (see Patent Document 3).

In addition, a blade having a cutting mechanism has been developed as a rotary blade (see Patent Document 4).

In the tablet sorting apparatus, the tablet is divided by the holding mechanism to maintain the position of the tablet, and the cutting edge of the cutting mechanism is cut into the tablet to reliably perform the cutting of the tablet.

Moreover, as long as the adjustment of the holding mechanism is properly performed, the tablet will remain in the appropriate cutting position at any time, and the tip of the cutting mechanism will change when the blade tip touches the intended portion of the tablet. Become small to the extent that you can't see it.

Here, a tablet dividing device (see Patent Document 5) which has been developed recently, and the tablet dividing device includes a holding mechanism for holding a tablet to be cut at a cutting position, and a cutting position for the cutting position a cutting blade that advances and retreats, a cutting mechanism that expands and reduces the opposing gap of the opposing blade to cut the tablet; and an operation sequence for specifying the cutting mechanism or an operation of the cutting mechanism and the holding mechanism The tablet cutting device for the cutting operation of the sequential cutting operation, and the cutting operation determining means developed by the cutting operation means for narrowing the opposing gap before the opposing blade is sandwiched by the opposing blade The tablet is held by the holding mechanism, and then the tablet is held by the holding mechanism from the opposing blade, and the tablet is held by the opposing blade only, and the tablet is released. After the tablet is held by the holding mechanism, the opposing blade is cut into the tablet.

In the tablet separating device (refer to the effect column in Patent Document 5), the tablet is released from the holding mechanism when the tablet is cut at the opposite edge when the tablet is cut, so that even if the opposing blade is cut, the tablet is generated. Deformation or displacement does not occur in the case where a reaction force acts from the holding mechanism to the tablet due to the deformation or displacement.

In this way, since it has been improved, the reaction from the holding mechanism does not occur because the cause of the change is considered to be the cause of the change in the cut-off state. The shape of the force is stabilized, and the variation in the amount of the tablet cut piece becomes smaller.

Further, (see Patent Document 6), after increasing the division accuracy, a lozenge dividing device has been developed in order to reduce the burden of adjustment and the like required to apply the tablet dividing device to various kinds of tablets of various shapes. The tablet dividing device includes a falling tablet guiding member in which a groove-shaped tablet dropping path is formed from the upper end to the lower end, and an ingot of the divided object that has been dropped through the tablet dropping path by opening and closing the path a blocking member that temporarily holds the cutting position in the middle of the tablet dropping path; and a cutting mechanism that cuts the tablet at the cutting position; and includes: cutting the cutting in the tablet dropping path a portion of the groove depth upstream of the position, a thickness adjustment mechanism for expanding and reducing the relative distance between the groove bottom of the drop path and the groove bottom surface of the groove depth defining member, and obtaining the thickness information of the tablet The thickness adjusting mechanism is actuated to control the relative distance to the thickness of the tablet.

The tablet dividing device (refer to the effect column in Patent Document 6) is provided by providing the thickness information of the smallest size among the shape information of the tablet to the control device, and then, by the control device and the thickness adjusting mechanism and the groove Deeply defining the cooperative action of the members to automatically make the distance between the groove bottom of the tablet drop path and the groove bottom surface facing the groove bottom surface suitable for the thickness of the tablet, thereby reducing the need for the tablet dividing device to be applied to different thicknesses The burden of adjustments required for the various lozenges. Further, (refer to the embodiment of Patent Document 6), in the means for the control device to obtain the thickness information of the tablet, Patent Document 6 is attached to the tablet cassette attached to the cartridge. A specific example of reading the data carrier, reading it directly from the operation unit, and downloading it from the host device via the communication line.

However, the tablet thickness information acquisition means for obtaining the thickness information of the tablet from the outside is premised on the fact that the thickness information of the tablet is known and the information is provided when required, so it is necessary to pre-specify the various tablets as the object to be divided. Quantitative size and keeping the data in a usable state, so its function is not sufficient to cope with drugs that have not been prepared in such a way, such as new drugs or drugs that need to be used immediately, and cannot be expected to be rapid and Appropriately respond to various tablets. Moreover, when there is no support means outside, the same function cannot be used and cannot be used.

For example, the download method cannot be used in a place where there is no communication device, and the method of reading from the data carrier cannot be used without attaching to an accessory such as a tablet box, and the operation input method is troublesome and has an input error. The way of downloading and reading from the data carrier is also not exempt from the erroneous input in the data login operation. Therefore, it is difficult to say that the above embodiment of the tablet separating device has been disclosed to be sufficient to give an understanding of the burden of adjustment required to individually reduce various kinds of tablets to be applied to different thicknesses.

Therefore, how to realize a tablet dividing device capable of automatically performing groove depth adjustment for a drop path of a tablet even if the thickness of the divided object tablet is unknown is a problem to be solved.

The tablet separating device (solution 1) of the present invention is provided to solve the problem as described above, and includes a falling tablet guiding member in which a groove-shaped tablet dropping path is formed from an upper end to a lower end; Open the path a blocking member that temporarily holds the tablet of the divided object that has fallen through the tablet dropping path, and that is held at the cutting position in the middle of the tablet dropping path; and cuts the tablet at the cutting position a mechanism; a groove depth defining member covering a portion of the dropping path of the tablet that is upstream of the cutting position; and a distance between a groove bottom for causing the dropping path of the tablet and a groove facing surface of the groove depth defining member a reduced thickness adjustment mechanism; detecting a tablet passing detection means for passing the tablet in a portion of the tablet dropping path upstream of the cutting position and covering the portion covered by the groove defining member; and monitoring while The tablet is actuated by the thickness adjustment mechanism by the detection result of the detecting means, and the relative distance is widened from a narrow locking distance to a wide full opening distance, and the thickness is adjusted when the passage of the tablet is detected. The control device that stops the mechanism and fixes the aforementioned relative distance to make the aforementioned relative distance suitable for the thickness of the tablet.

Further, in the tablet dividing device (solution 2) of the present invention, in the tablet dividing device of the above-described solving device 1, the cutting mechanism includes an electric opposing blade that is controlled by the control device, and the aforementioned The opposing gap of the opposing blade is narrowed from the expanded state to hold the tablet and then further narrowed to cut the aforementioned tablet, and the tablet dividing device is provided with a driving current for detecting the driving current of the opposing blade. In the control device, the control device is configured to change the traveling speed of the opposing blade and the temporary stop of the blocking member with respect to the tablet from a predetermined period of time after the cutting blade holds the tablet to the tablet. Monitoring one or both of the hold, and monitoring the detection result of the drive current detecting means The predetermined amount of time is applied to the thickness of the tablet by sandwiching the tablet with the opposing blade and detecting the position of the opposing blade based on a sudden increase in the drive current during the clamping.

The tablet dividing device (solution 1) of the present invention as described above is configured to control the depth of the groove of the drop path, that is, the groove bottom of the drop path of the tablet, by adjusting the groove depth of the drop path. The relative distance from the groove facing surface of the member defining the groove depth is increased from a very narrow blocking distance. When the relative distance exceeds the thickness of the tablet, the tablet falls immediately, and the drop is measured by the tablet passing means. The thickness adjustment mechanism is stopped by the control of the control device that monitors the detection result, and the groove depth of the drop path is thus fixed. Thus, as long as the thickness of the tablet is between the blocking distance and the full opening distance, the groove depth of the dropping path can be automatically adapted to the thickness adjustment of the tablet regardless of whether or not the thickness of the tablet has been determined in advance.

Therefore, according to the present invention, it is possible to realize a tablet dividing device capable of automatically performing groove depth adjustment for a drop path of a tablet even if the thickness of the divided tablet is unknown.

Further, the tablet dividing device (solution 2) of the present invention changes the traveling speed of the opposing blade before the cutting of the tablet by the facing blade until the tablet is cut, and/or the blocking member for the tablet Since the release is temporarily maintained, the division is stable and the fluctuation of the amount of the tablet cut piece is small, and the predetermined time period for performing the speed change and the release is also reduced by the device itself. Different thickness The burden of adjustments required for the tablet. In other words, the adjustment of the predetermined period is generally performed by changing the setting value related to the passage of time and the traveling position of the facing blade, but when the adjustment is performed, even if the control device is used, the cutting state is affected. The action can still automatically detect the good clamping position, and grasp the opposing gap of the opposing blade at this time as the thickness of the tablet which can be suitable for the cutting of the tablet, and then decide the speed in the course of the facing blade. The set value of the predetermined period of the change and the release is fixed to a value corresponding to the arrival time of the thickness of the opposite gap, so that the speed change and the release can be automatically performed regardless of whether the thickness of the tablet has been determined in advance. The predetermined period of time is suitable for the adjustment of the thickness of the tablet.

In the holding mechanism 30 (see FIGS. 1 to 3), the tablet 10 of the divided object cut by the cutting mechanism 40 is blocked from the cutting position 33 in the middle of the tablet dropping path 32 as described above. In cooperation with the cutting mechanism 40, the tablet holding by the holding mechanism 30 is released, and a plate-shaped falling tablet guiding member 31 disposed between the tablet feeder base 27 and the relay portion 26 is further provided. And by using the upper end as a fulcrum The lower end swingable movable member constitutes one of the pair of blocking members 34. Further, a groove depth defining member 37 and a thickness adjusting mechanism 38 are further provided in order to adjust the posture and direction of the tablet 10 dropped by the upstream partial path 32a of the tablet dropping path 32.

Further, in order to prevent the tablet cutting sheets 10b, 10c from being scattered from the left side branch path 32b and the right side branch path 32c belonging to the downstream portion of the path of the tablet dropping path 32, the holding mechanism 30 is further provided with a cover including the left side branch path 32b and the right side. The surface of the lower half of the tablet guiding member 31 and the front fixed cover 36 are dropped by the branch path 32c (see FIGS. 1(c), (d), 2nd (d), and 2nd ( e)). These members and mechanisms 34, 36, 37, and 38 are disposed along the tablet dropping path 32, and are attached to the falling tablet guiding member 31 (see FIGS. 1 to 3).

The tableting guide member 31 of the holding mechanism 30 is also provided with a tablet passing detection sensor 39 for detecting that the tablet 10 dropped from the tablet container 21 and put into the tablet dropping path 32 is dropped by the tablet.

The tablet is easily used by the detecting sensor 39 in an optical mode capable of detecting in a non-contact manner, and includes, for example, a light-emitting element 39b disposed opposite to both sides of the upstream portion path 32a of the tablet dropping path 32, and Light receiving element 39c.

The falling tablet guiding member 31 (see FIGS. 1(b) and 1(c)) is formed of a vertical thick plate and is fixed to the front plate and the rear plate of the main body portion 24 in a substantially parallel state. The inside of the body portion 24.

The forward surface (see Fig. 1 (d), Fig. 2) of the both sides (front and back/front) of the tablet guiding member 31 is dropped, and is formed to guide the falling The lozenge of the lower tablet 10 falls down the path 32.

The tablet dropping path 32 (refer to FIG. 2(a)) is formed by cutting or pressing on the surface of the falling tablet guiding member 31, and dropping the tablet guiding member The upper end of 31 continues to the lower end. In the cutting position 33 set in the middle of the tablet dropping path 32, a slit 35 for allowing the cutting edge of the cutting mechanism 40 to pass through the falling tablet guiding member 31 is formed by perforation.

The upstream portion path 32a of the portion on the upstream side of the cutting path 33 in the tablet dropping path 32 is a straight path, and the downstream side portion of the tablet dropping path 32 is at the cutting position 33. More specifically, at the slit 35 at the center of the cutting position 33, the left and right bifurcation paths 32b and 32c are divided into two longitudinal parallel directions from the position to the right and left.

The blocking member 34 divides the blocking member 34 into a pair of left-side path opening and closing members 34b and right-side path opening and closing members 34c corresponding to the above-described two divisions, and the opening and closing members 34b, 34c are all oscillated according to the control of the control device 23, and the left-side path opening and closing member 34b is opening and closing of the branch opening from the upstream partial path 32a to the left branching path 32b, and the right-side path opening and closing member 34c opens and closes the branch opening from the upstream partial path 32a to the right branching path 32c.

In the tablet dividing device 20 of the present embodiment, the disk-shaped tablet 10 is equally divided into two sides, so that the slit 35 is formed in the longitudinal direction of the center of the cutting position 33, and the left-side path opening and closing member 34b and the right side are formed. The path opening and closing member 34c is disposed to be bilaterally symmetrical about the slit 35. Left path The opening and closing member 34b and the right-side path opening and closing member 34c, that is, the pair of blocking members 34, when the tablet 10 is temporarily held at the cutting position 33, the lower ends are brought close to each other to form a V-shape, and at the cutting position. When the tablet cutting pieces 10b, 10c are to be introduced into the left side branch path 32b to be dropped, the left side path opening and closing member 34b is swung to the upstream side. The part path 32a communicates with the left side branch path 32b, and when the tablet cut pieces 10b, 10c are to be guided to the right side branch path 32c to fall, the right side path opening and closing member 34c is swung to make the upstream part path 32a and the right side. The branch path 32c is connected to each other. When the tablet cut pieces 10b and 10c are simultaneously dropped into the left side branch path 32b and the right side branch path 32c, the left side path opening and closing member 34b and the right side path opening and closing member 34c are simultaneously swung toward the open side. .

The groove depth defining member 37 (see FIGS. 1(c), (d), 2(c), (e), and 3) is made of, for example, a thin plate made of a transparent or opaque hard resin. The upstream portion of the path 32a of the tablet dropping path 32 is covered by the upstream opening portion 32a of the tablet dropping path 32 from the front of the groove opening, and the upstream portion of the path is covered. The groove bottom of the 32a is parallel to the back/back of the groove depth defining member 37, that is, parallel to the bottom surface of the groove. Further, the groove depth defining member 37 is supported to be supported by the thickness adjusting mechanism springs 37b, 37c in a state of maintaining the parallel state, so that the thickness adjusting mechanism 38 can control the groove depth defining member in accordance with the control of the control device 23. The movement of 37 in the front-rear direction increases and decreases the relative distance G between the groove bottom of the tablet dropping path 32 and the groove bottom surface facing the groove bottom surface.

The cutting mechanism 40 (see FIGS. 1 and 4) is provided with opposing blades 41 and 42 including a front blade 41 that is moved forward and backward toward the cutting position, and a rear blade 42 that is rearward. The opposing gaps of the opposing blades 41, 42 are enlarged and reduced, and the tablet 10 at the cutting position 33 is equally cut to the left and right. The front blade 41 is supported by a high-rigidity rod-sleeve fitting type door type support mechanism, and the front blade advancing and retracting member 43 that moves to the rear is supported by the slit 35 at the cutting position 33. The front side is moved forward and backward by the slit 35 toward the rear in accordance with the control of the control device 23. The trailing edge 42 is supported by the blade advancing and retracting member 44 after moving toward the rear side of the falling tablet guiding member 31, and the tablet 10 is directed toward the cutting position 33 while passing through the slit 35 in accordance with the control of the control device 23. Move forward or backward.

In the cutting mechanism 40, the opposing blades 41 and 42 are actuated by the control of the compliance control device 23, and the opposing gaps of the opposing blades 41 and 42 are enlarged and contracted to sandwich and cut the tablet 10 (Fig. 4) The manner of clamping and cutting is shown in time series, wherein (a) to (f) are related to the initial tablet cutting, (g), (h), (e), (f) and second In the meantime, the tableting agent 10 is clamped so as to be suspended from the groove bottom of the groove dropping path 32 and suspended from the groove bottom surface of the groove depth defining member 37 before the cutting is completed. Then complete the cut. Further, at a predetermined period (the period t2 to be described later) from when the opposing blade 41, 42 holds the tablet 10 to when the tablet 10 is cut, the originally closed blocking member 34 is opened under the control of the control device 23. Since the temporary holding of the blocking member 34 with respect to the tablet 10 is also released, the tablet 10 is held by only the opposing blades 41, 42 before the cutting is completed.

The details of the control device 23 are omitted (see Fig. 1(b), Fig. 5(a)), but it is an electronic control device composed of, for example, a programmable microprocessor system or a program controller, and for the tablet feeder base 27 and the holding mechanism 30 The cutting mechanism 40 cooperates to reliably perform the sequential supply and the cutting of the tablet 10, and performs the operation control of the electric motor or the like of each member. The motors for driving the front edge advancing and retracting member 43 and the front blade 41 in the motors are servo motors 45 (see Fig. 5(a)), and when the control device 23 sends the position command Ps to supply the drive current to the servo When the servo controller 46 of the motor 45 is used, the rotation angle of the servo motor 45 and the advance and retreat positions of the front blade advancing and retracting member 43 and the front blade 41 follow the position command Ps by the feedback control of the servo controller 46.

The feedback control is generally a dual-loop feedback, specifically, a drive current detection by a current transformer, a transducer, or the like. The member 47 detects the drive current supplied from the servo controller 46 to the servo motor 45, and returns the drive current detection signal If of the drive current detecting member 47 to the servo controller 46 in a minor loop, and encodes it by the encoder. A position detecting member 48 composed of an encoder, a resolver, or the like detects the rotation angle of the servo motor 45, and returns the position detecting signal Pf of the position detecting member 48 to the servo control in a major loop. In the case of the controller 46, the drive current detection signal If obtained by detecting the drive current of the servo motor 45 and the drive current of the counter blade 41 is also sent to the control device 23.

The driving current detection signal If is determined from the opposite edge 41, 42 The holding of the tablet 10 is started until the predetermined period t2 until the tablet 10 is cut, so that it is suitable for the thickness of the tablet 10 and is input to the control device 23, but in addition, it is also formed as the control device 23 for the ingot. The distance G between the groove bottom of the upstream portion path 32a of the agent drop path 32 and the groove bottom surface of the groove depth defining member 37 is adapted to the thickness of the tablet 10, and the tablet is detected by the detecting sensor 39 to pass the tablet 10 The composition is input by the detection result. Then, the control device 23 is sequentially performed immediately after the power is turned on or immediately after the replacement of the tablet cassette 21, and when the initialization is instructed by the operation unit 22, in accordance with the use of the tablet through the detection sensor 39. The automatic adjustment of the relative distance G of the tablet by the detection result is automatically adjusted based on the predetermined period t2 of the drive current detection signal If obtained by the drive current detecting means 47.

First, the automatic adjustment of the relative distance G will be described in detail (see Fig. 3). When the control device 23 is to position the groove depth defining member 37 at a certain position (see Fig. 3(a)), the thickness adjusting mechanism 38 is actuated to move the groove depth defining member 37 toward the upstream portion of the tablet dropping path 32. The groove bottom of the path 32a moves so that the relative distance G becomes a very narrow blocking distance to the extent that the tablet cannot pass (see Fig. 3(b)). In this state, the first tablet 10 that has been fed from the tablet cassette 21 via the guide of the tablet feeder base 27 is waited until the tablet 10 is loaded (see Fig. 3(c)). By monitoring the detection result of the sensor 39, the thickness adjustment mechanism 38 is actuated to move the groove depth defining member 37 at a slower speed in a direction away from the groove bottom, so that the relative distance G is oriented from the blocking distance. The wide open distance is widened (see Figure 3 (d)).

Then, when the relative distance G is expanded to be slightly wider than the thickness of the tablet 10, the tablet 10 is dropped by the upstream portion path 32a of the tablet dropping path 32, and the tablet 10 is sensed by the tablet through the detection. At the time of the device 39 (refer to Fig. 3(e)), the tablet is notified to the control device 23 by the detection sensor 39 of the detection result of the passage of the tablet 10. The control device 23 moves the thickness adjustment mechanism 38 while monitoring the detection result of the sensor by the detection sensor 39. When the notification of the receipt of the tablet 10 is received, the thickness adjustment mechanism 38 is immediately stopped to move the groove depth defining member. The position 37 is maintained at this time, and the automatic adjustment of the relative distance G is ended, so that the second and subsequent tablets 10 fall in the tablet drop path 32 of the relative distance G. The control device 23 is such that the relative distance G is adapted to the thickness of the tablet 10 by fixing the relative distance G to a state slightly larger than the thickness of the tablet 10.

Next, the automatic adjustment of the predetermined period t2 will be described in detail (see FIGS. 4 and 5). Here, since the automatic adjustment of the predetermined period t2 is performed based on the drive current of the front blade 41, the automatic adjustment of the predetermined period t2 is equivalent to the automatic decision of the advance/retract position P2 of the blade 41 in the front-rear direction. The control device 23 expands the opposing gaps of the opposing blades 41, 42 to the maximum for the first tablet 10 of unknown thickness, and moves the leading edge 41 back to the position P0 (see Fig. 4(a)), so that When the tablet 10 is dropped, it is not blocked by the opposing blades 41, 42 and smoothly reaches the cutting position 33, and then the relative gap of the opposing blades 41, 42 is reduced. Then, when the first tablet 10 is put in and the automatic adjustment of the aforementioned relative distance G is completed, the position P1 is determined from the relative distance G. Specifically, one position P1 of the front blade 41 is determined such that the opposing gaps of the opposing blades 41, 42 become slightly wider than the relative gap G. The tablet 10 can smoothly enter the distance between the opposing blades 41, 42.

Further, when the first tablet 10 reaches between the facing blades 41, 42 (refer to Fig. 4 (b)), from this point of time (refer to t0 in Fig. 5 (b)), the control device 23 causes the front The blade 41 travels in a direction in which the opposing gaps of the opposing blades 41, 42 are narrowed while the trailing edge 42 travels at a low speed. In the meantime, the control device 23 performs control such that the high speed advance of the front blade 41 continues until the front blade 41 reaches the advancing and retracting position P1 (refer to the position command Ps of the period t0 to t1 in Fig. 5(b)). When the bottom of the groove of the tablet dropping path 32 is slightly retracted, the blade 42 temporarily stops traveling when the tablet 10 starts to float from the bottom of the groove (see FIG. 4(c)), and waits until the leading edge 41 reaches the position P1.

When the front edge 41 reaches the position P1 (refer to the period t1 in Fig. 4(d) and Fig. 5(b)), the control unit 23 causes the opposing blades 41, 42 to travel at a low speed until the opposing gaps of the opposing blades 41, 42 The narrowing is made to the cutting completion distance (refer to the position command Ps of the period t1 to t3 in Fig. 5(b)). In the meantime, when the current blade 41 advances to the advancing and retracting position P2 and the opposing blades 41 and 42 hold the tablet 10 (see Fig. 4(e)), the tablet 10 resists the progress of the opposing blades 41, 42. The drive current supplied from the servo controller 46 to the servo motor 45 is rapidly increased, and the drive current detection signal If is also correspondingly increased, and the drive current detection signal If is thus exceeded the threshold value It (refer to the period in Fig. 5(c)). T2). Since the control device 23 monitors the drive current detection signal If, it is possible to grasp the period t2 (predetermined period) and the advance/retract position P2 (clamping position) when the opposing blades 41, 42 hold the tablet 10 in accordance with the detection of the drive current.

The control device 23 regards the above-described tablet holding period t2 as the slave facing blade 41, 42 by the sudden increase of the drive current detecting signal If. The holding of the tablet 10 starts at a predetermined period t2 until the tablet 10 is cut. Further, at the predetermined period t2, the temporary holding of the blocking member 34 for the tablet 10 is released regardless of the first tablet 10 or the second tablet 10, and the tablet 10 is changed for the second and subsequent tablets 10 The travel speed of the front edge 41 in the opposing blades 41,42. That is, the second or subsequent tablet 10 to be processed after the automatic adjustment of the predetermined period t2 is completed changes the traveling speed of the leading edge 41 from the high speed advance to the low speed forward at the predetermined time period t2 (refer to FIG. 5 (refer to FIG. 5 ( d) The position command Ps) in the period t1 to t2, and the speed change in the period t1 is only the first tablet 10 (see Fig. 5(b)).

From the predetermined period t2 to the period t3, the control device 23 advances the facing blades 41, 42 at a low speed regardless of the first or second tablet 10 (refer to Figs. 5(b) and (d) In the position command Ps) from the period t2 to the time t3, when the current blade 41 reaches the advancing and retracting position P3 (see FIG. 4(f)), the cutting of the tablet 10 is completed, so that the opposing blades 41 and 42 are quickly returned. The high-speed reverse travel (refer to the position command Ps of the period t3 to t4 in FIGS. 5(b) and (d)), and it is determined that the lozenge falls first in the groove of the upstream portion of the path 32a of the path 32. The relative distance G between the bottom and the groove depth defining member 37 facing the groove bottom surface is suitable for the thickness of the tablet 10, and the relative distance G for the second and subsequent tablets 10 is adjusted so that the opposing gap ratios of the opposing blades 41, 42 are adjusted. Since it is only slightly wide, the front blade 41 is stopped at the position P1 corresponding to the relative distance G (refer to FIGS. 4(g) and (h)).

Next, with respect to the tablet dividing device 20 of the first embodiment, the use and operation will be described with reference to the drawings. Figure 1 (a), (b) segmentation The oblique view and the right side view of the device 20 show the state in which the tablet case 21 and the adapter 25 are attached to the main body portion 24. 3(a) to 3(e) are longitudinal sectional right side views of the upstream portion path 32a of the tablet dropping path 32, showing the groove bottom of the upstream portion path 32a of the tablet dropping path 32 in time series. The relative distance G of the groove depth defining member 37 facing the groove bottom surface is suitable for the operation at the time of automatic adjustment of the thickness of the tablet 10.

Further, FIGS. 4(a) to 4(h) are right side views of important portions of the cutting mechanism 40, showing the time series of the cutting of the tablet 10 at the cutting position 33 by the opposing blades 41, 42. The action, wherein (a) to (f) are related to the initial tablet cutting, and (g), (h), (e), (f) are related to the second and subsequent tablet cutting. Further, Fig. 5(a) is a block diagram of a drive system and a control system relating to the front blade advancing and retracting member 43, (b) is a time chart showing a waveform example of the position command Ps before the cutting adjustment, and (c) A time chart showing an example of a waveform of the drive current detection signal If, and (d) is a time chart showing an example of a waveform of the position command Ps after the cut adjustment. Further, Fig. 6 (a) to (f) are each a surface view of an important portion of the holding mechanism 30, and the tablet 10 which is put into the tablet dropping path 32 is displayed in time series and is cut to become a tablet cutting piece. 10b, 10c after the process of discharge.

Before the tablet cutting, a tablet box 21 containing a plurality of tablets 10 for cutting the divided objects is attached to the tablet feeder base 27, and the adapter 25 is inserted into the body portion 24 (refer to Figure 1 (a), (b)). Then, when the tablet dividing device 20 is operated by turning on the power source or the like, the tablet dividing device 20 is first brought into an initial state, and is prepared to perform automatic adjustment of the relative distance G and automatic adjustment of the predetermined period t2. That is, the lozenge falls The distance G between the groove bottom of the upstream partial path 32a of the lower path 32 and the groove bottom surface of the groove depth defining member 37 becomes a narrow locking distance (see Fig. 3(b)), and the opposing blade 41 is retracted to the position. P0 increases the opposing gap of the opposing blades 41, 42 to the maximum (see Fig. 4(a)). Further, the holding mechanism 30 closes the left side path opening/closing path 34b and the right side path opening and closing path 34c of the blocking member 34 located immediately below the cutting position 33, but the cutting position 33 does not have the tablet 10, and the cutting position 33 It is empty.

In this state, when the operation unit 22 is operated to cause the tablet dividing device 20 to start the cutting process, the drive motor of the tablet feeder base 27 is actuated, whereby a tablet 10 is driven from the driven tablet case. 21 falls and drains. Then, the original tablet 10 is dropped into the tablet dropping path 32 of the holding mechanism 30 via the guide of the tablet feeder base 27, but at this point, the upstream portion of the path 32a of the tablet falling path 32 is Since the distance G between the groove bottom and the groove depth defining member 37 facing the groove bottom surface is narrowed by the blocking distance, it is temporarily held at the upper end of the tablet dropping path 32 (see FIG. 3(c)).

Then, the groove depth defining member 37 is moved to widen the relative distance G (see FIG. 3(d)), and when the relative distance G is changed to be slightly wider than the thickness of the tablet 10 (refer to FIG. 3(e)) When the movement of the groove depth defining member 37 is stopped and the relative distance G is kept fixed, the tablet 10 is dropped by the upstream portion path 32a of the tablet dropping path 32 (refer to Fig. 6 (a), (b)). However, at this time, the automatic adjustment of the relative distance G is completed, and the relative distance G is in a state suitable for the thickness of the tablet 10, so that the tablet 10 maintains its posture in the thickness direction toward the front-rear direction and smoothly and rapidly falls. Until reaching the cutting position 33 (refer to Fig. 6 (c)).

The tablet 10 that has reached the cutting position 33 stops at the point where it abuts against the blocking member 34, and is held between the two blocking members 34, that is, positioned between the left path opening and closing member 34b and the right path opening and closing member 34c. The center is held above the slit 35 (refer to Fig. 6(c)). At this time, the tablet 10 is held at the contact portion of the groove bottom of the tablet dropping path 32 of the falling tablet guiding member 31 in the holding mechanism 30 with the two blocking members 34, and is not opposed to the opposing blade 41, 42. The contact enters the opposing gaps of the opposing blades 41, 42 (see Fig. 4(b)).

The tablet 10 is cut by the cutting mechanism 40 from this state. However, in the case of the first tablet 10, the predetermined period t2 is also adapted to the automatic adjustment of the thickness of the tablet 10. In detail, when the first tablet 10 reaches between the facing edges 41, 42 (refer to FIG. 4(b)), the leading edge 41 is advanced at a high speed (refer to the period t0 to t1 in FIG. 5(b)). The position command Ps) simultaneously causes the trailing edge 42 to travel at a low speed to narrow the opposing gaps of the opposing blades 41, 42 while the trailing edge 42 temporarily stops traveling when the tablet 10 is suspended from the bottom of the groove (see 4th) Figure (c)). On the other hand, when the current blade 41 travels at the high speed to the advancing and retracting position P1 (see FIG. 4(d)), the speed is changed there and the vehicle advances to the advancing and retracting position P3 at a low speed (refer to the period in FIG. 5(b)). Position command Ps) from t1 to t2 to t3. After the leading edge 41 reaches the position P1, the trailing edge 42 also begins to travel at a low speed.

Then, when the leading edge 41 advances to the position P2, the opposing gaps of the opposing blades 41, 42 become extremely narrow, and the opposing blades 41, 42 hold the tablet 10 (refer to Fig. 4(e)). In this way, the driving current detection signal If will increase correspondingly, causing the driving current detection signal If to exceed the threshold value 1t (refer to FIG. 5). In the period t2) in (c), the control device 23 can grasp the period t2 (predetermined period) and the advance/retraction position P2 (clamping position) at which the opposing blades 41, 42 hold the tablet 10.

In this way, it is possible to detect the signal If according to the drive current detected by the drive current detecting means 47, and not only the period from when the opposing blades 41, 42 hold the tablet 10 to when the tablet 10 is cut, and The predetermined period t2 of the period in which the forward speed of the front blade 41 and the temporary movement of the blocking member 34 to the release of the tablet 10 are performed in the opposing blades 41, 42 is automatically adjusted to be suitable for the tablet 10. thickness.

Then, when the front blade 41 reaches the advancing and retracting position P3 (see FIG. 4(f)), the tablet 10 is cut and divided into two tablet cutting pieces 10b and 10c (see FIG. 6(d)). Thereafter, the opposing blades 41, 42 are reversely advanced at a high speed (refer to the position command Ps of the period t3 to t4 in Fig. 5(b)), and the opposing gaps of the opposing blades 41, 42 are enlarged until the leading edge 41 is retracted. It stops at the advance and retreat position P1 (refer to Fig. 4 (g)). Also. When the tablet 10 is divided into the tablet cutting sheets 10b and 10c, the blocking member 34 is swung to release the locking of the tablet dropping path 32 (refer to Fig. 6(e)), and the cutting position 33 and the tablet are dropped. The left side branch path 32b of the downstream part of the path 32 communicates with the right side branch path 32c, so that the left half of the tablet cut piece 10b is dropped from the left side branch path 32b and is accommodated in the left side receiver 25b, and the right half of the ingot The agent cut piece 10c is dropped from the right side branch path 32c and is accommodated in the right side receiver 25c (refer to Fig. 6 (f)).

As a result, the initial cutting of the tablet 10 is completed, and the automatic adjustment of the relative distance G and the automatic adjustment of the predetermined period t2 are completed. Then, because the necessary adjustments have been completed, it can be in a stable state and The cutting of the second and subsequent tablets 10 is performed promptly.

Although the detailed description of the above-mentioned repetition is omitted, when the second and subsequent tablets 10 are discharged from the tablet cassette 21 and dropped into the tablet dropping path 32 of the holding mechanism 30, the tablet is dropped. The distance G between the groove bottom of the upstream portion path 32a of the path 32 and the groove bottom surface of the groove depth defining member 37 is fixed to a state slightly larger than the thickness of the tablet 10 (refer to Fig. 3(e)), and the front is made The blade 41 is stopped at the advancing and retracting position P1, and the opposing gaps of the opposing blades 41 and 42 are slightly wider than the relative distance G (see FIG. 4(g)).

Therefore, the tablet 10 is immediately dropped from the upstream portion path 32a of the tablet dropping path 32 (refer to Fig. 6 (a), (b)), but since the relative distance G in the upstream portion path 32a is suitable for the ingot Since the thickness of the agent 10 is maintained, the tablet 10 maintains its posture in the thickness direction toward the front-rear direction, and thus falls smoothly and rapidly. Then, when the tablet 10 is dropped to the cutting position 33, it is blocked by the blocking member 34 in the closed state and is returned thereto (refer to Fig. 6(c)), at this time due to the opposing blades 41, 42 The opposing gap is also in a state suitable for the thickness of the tablet 10, so that the tablet 10 is not blocked by the opposing blades 41, 42 and enters the opposing gaps of the opposing blades 41, 42 (refer to Fig. 4 (h). )) is located above the slit 35 and is held by the groove bottom of the tablet dropping path 32 and the contact portion between the two blocking members 34 (refer to Fig. 6(c)).

The tablet 10 is cut by the cutting mechanism 40 from this state. However, in the case of the second and subsequent tablets 10, since the predetermined period t2 is completed to be suitable for the automatic adjustment of the thickness of the tablet 10, the leading edge The traveling of 41 proceeds from the advancing and retracting position P1 to the advancing and retracting position P2 at a high speed. So make the phase The clamping of the blade 41, 42 to the tablet 10 is rapidly performed in a short time (refer to Fig. 4 (e)). In the meantime, the blade 42 is suspended from the bottom of the groove by the blade 42, and the tablet 10 is held by the opposing blades 41, 42. Then, after the opposing blades 41, 42 hold the tablet 10, the temporary holding of the blocking member 34 for the tablet 10 is released, while the traveling speed of the leading edge 41 is switched from high speed to low speed, so that the opposing blades 41, 42 The tablet 10 that has escaped from the undesired external force by the holding mechanism 30 is cut (see FIG. 4(f)), and the tablet 10 is cut and divided into two tablet cut pieces 10b and 10c (refer to 6 (d)).

Further, the blocking member 34 is swung to release the locking of the tablet dropping path 32 (refer to Fig. 6(e)), and the cutting position 33 is thus separated from the left side divergent path 32b and the right side divergent path of the downstream portion of the tablet dropping path 32. Since the 32c is in communication, the left-side loom cut piece 10b is dropped from the left side branch path 32b and discharged to the left side receiver 25b, and the right half of the tablet cut piece 10c is dropped from the right side branch path 32c and discharged to the right side receiver 25c ( Refer to Figure 6 (f)).

In this way, the cutting of the second and subsequent tablets 10 can enjoy the effect of automatic adjustment by the first tablet 10, and the cutting can be performed in a stable state and quickly.

In the tablet thickness information acquisition means of the tablet separating apparatus of the above-described embodiment, the thickness information of the tablet is obtained only by measurement in the device, and the thickness information of the tablet is not obtained from the outside, but it is not impossible to obtain it from the outside. For example, in addition to the measurement in the device, it is also tried from the outside. When it is obtained from the outside, the value or the slightly smaller value is used as the initial value of the relative distance between the groove bottom of the tablet drop path and the groove depth defining member facing the groove bottom surface.

In the above embodiment, the automatic adjustment of the predetermined period t2 is performed according to the driving current of the front blade 41, but the automatic adjustment of the predetermined period t2 may be performed according to the driving current of the trailing edge 42, or may be based on the opposing blade 41, 42. The driving current of the two, for example, the total current is performed.

The operation portion 22 provided in the above embodiment is not essential. For example, a series of operations may be started when the tablet 10 is placed at the upper end of the tablet drop path. If the discharge of the tablet cut sheets 10b, 10c is not adversely affected, the adapter 25 and the relay portion 26 are not essential, and if the automatic sequential supply of the tablet 10 is not required, the tablet feed is not required. The base 27 and the tablet cassette 21 are also not required. Also in the case of the driving member of the blocking member 34, it is not necessary to explicitly set the driving member in an electric or fluid-driven manner, and it can be incorporated in a transmission mechanism of a holding mechanism or a cutting mechanism, etc., by For example, the manual handle is pressed or rotated to drive.

In the above embodiment, the front blade 41 is stopped at the advancing and retracting position P0 (refer to the period t0 before the fifth drawing) in the automatic adjustment of the relative distance G, but it is also possible to automatically adjust the relative distance G. The front blade 41 is moved in accordance with the change in the relative distance G so that the opposing gaps of the opposing blades 41, 42 are maintained to be slightly wider than the relative distance G, and the advancement and retreat position of the front blade 41 is simultaneously performed while the adjustment of the relative distance G is completed. The determination of P1 is completed and the positioning action of the front edge 41 to the advance and retreat position P1 is completed. This not only shortens the adjustment time associated with the original tablet 10, but also stabilizes the home position when the original tablet 10 reaches the cutting position 33.
