Description

TECHNICAL FIELD

[0001] The present application relates to a kind of full-automatic capsule processing equipment. BACKGROUND

[0002] Capsule is composed of two pieces of insertable coating and powdered medicine or liquid medicine in the two coatings. The processing of capsule needs to go through several steps of medicine filling (i.e. putting medicine into the two coatings), sealing and drying. At present, there are capsule filling machines on the market that are specially used for filling capsules, capsule sealing machines that are specially used for sealing capsules, and drying equipment that dries capsules after sealing.

[0003] The patent document with publication number "CN210355393U" discloses a kind of capsule full-automatic processing flow line, mainly including machine body, capsule filling unit, capsule drying unit, capsule filling unit and capsule drying unit are connected through capsule sealing unit, capsule filling unit includes feeding mechanism, liquid adding mechanism, pressing mechanism, capsule discharging mechanism and turntable mechanism, capsule sealing unit includes capsule conveying belt, the capsule conveying belt is uniformly distributed with capsule containing groove for preventing capsules, the sealing mechanism is arranged on the capsule conveying belt, a capsule receiving roller and a capsule output plate are arranged at one end of the capsule conveying belt, and a transfer mechanism is arranged between the turntable mechanism and the capsule output plate. Compared with manual processing, the capsule full-automatic processing flow line has higher processing efficiency and avoids secondary pollution.

[0004] However, the above-mentioned capsule full-automatic processing flow line has the following problems:

[0005] (1) After the capsules on the conveying belt at the feeding mechanism fall into the turntable mechanism, it cannot be ensured that every capsule has the cap upwards and the body downwards (because only when the cap is upwards and the body is downwards, the cap and the body can be separated by the turntable mechanism, and then the liquid adding mechanism can add liquid to the body), and there will inevitably be capsules with the cap downwards and the body upwards, which cannot be injected. The device does not have any mechanism to detect such unqualified capsules (capsules that cannot be injected) and does not have any rejection mechanism, so it is necessary to improve the capsule filling unit and reject unqualified capsules;

[0006] (2) The device still has the problem of low production efficiency, for example, at the transfer mechanism, only a single row of capsules can be transported at a time. If multiple rows of capsules are simply placed on the turntable by increasing the number of placement slots, the corresponding capsule discharge mechanism also needs to be improved, and multiple rows of ejector rods must be provided, or the ejector rods need to be repeatedly changed in angle or horizontally displaced for repeated ejection work to discharge multiple rows of capsules. Therefore, it is necessary to improve the existing device to produce capsules more quickly and efficiently.

[0007] (Three) transport mechanism to convey capsules to the capsule transport conveyor, through the capsule transport conveyor to the capsule drying unit for drying treatment, in the process, there will be more capsules on the capsule transport conveyor cannot accurately into the capsule transport conveyor on the capsule placement slot, and the part of the capsule which has not entered the capsule placement slot cannot smoothly enter the drying unit for drying, also need to be rejected, so the part of the waste rate is higher, it is necessary to reduce the waste rate of this part. SUMMARY

[0008] The technical problem to be solved by the present application is to provide a full-automatic capsule processing equipment.

[0009] To achieve the above object, the present application provides the following technical scheme: a full-automatic capsule processing equipment, comprising a machine body, the longitudinal one end of the machine body is a capsule filling unit, the other end is a capsule drying unit, the capsule filling unit and the capsule drying unit are connected through a capsule sealing unit; characterized in that: the capsule filling unit comprises a first blanking mechanism, a liquid adding mechanism, a second blanking mechanism, a pressing mechanism, a transfer device and a turntable mechanism, the first blanking mechanism, the liquid adding mechanism, the second blanking mechanism, the pressing mechanism and the transfer device are connected in sequence through the turntable mechanism; the turntable mechanism comprises a rotatable first turntable, a plurality of groups of first capsule transfer assemblies distributed on the outer periphery of the first turntable and distributed along the circumference of the first turntable; the capsule filling unit further comprises a detection mechanism distributed between the first blanking mechanism and the liquid adding mechanism, and a rejection mechanism distributed between the second blanking mechanism and the pressing mechanism.

[0010] The technical scheme is adopted, the detection mechanism is additionally arranged for detecting unqualified capsules, the liquid adding mechanism can add liquid to the capsules which can be added liquid, and then the waste capsule removing mechanism removes the waste capsules, thereby solving the problem that the waste capsules cannot be detected in the prior art, avoiding that the liquid adding mechanism adds liquid to the waste capsules, reducing waste, and avoiding the generation of empty capsules, so that no empty capsules are generated after the capsules are processed by the device; further, the rotating disc mechanism has high integration and can minimize the overall floor area. The specific operation principle is as follows: the hard capsules are fed, sorted and oriented by the first feeding mechanism (the first feeding mechanism can be directly realized by using the prior art, such as an empty capsule directional arrangement device); the rotating disc mechanism receives the hard capsules transported from the first feeding mechanism, and then separates the capsule caps and the capsule bodies, in the process, capsules in a state that the orientations do not meet the requirements (i.e., the capsule cap faces downward and the capsule body faces downward) are generated, and the capsules cannot be separated by the rotating disc mechanism; therefore, the detection mechanism detects the hard capsules, and detects the unqualified capsules; then, the rotating disc mechanism continues to drive the hard capsules to move to the liquid adding mechanism, and the liquid adding mechanism injects liquid medicine into the separated capsule bodies; the capsules after the liquid adding process continue to move with the rotating disc mechanism to the second feeding mechanism, the second feeding mechanism injects the soft capsules or the medicine pellets into the capsule bodies, and in this process, there is no requirement for sorting and orientation, and only the feeding work needs to be completed; then, the waste removing mechanism removes the unqualified capsules detected by the detection mechanism, and the pressing mechanism presses the capsule bodies and the capsule caps, the transfer device transfers the pressed hard capsules to the capsule sealing unit, the sealed capsules are transported to the capsule drying unit for drying, and finally, the finished products are discharged.

[0011] The detection mechanism can further include a detection frame and a plurality of groups of sensors which are detachably and fixedly installed on the detection frame.

[0012] The technical scheme is adopted, when the sensors are installed, the sensors only need to be placed on the movement track of the first capsule transporting assembly, and when a group of the first capsule transporting assembly passes through the place, the plurality of groups of sensors detect the capsule placing slots on the first capsule transporting assembly and record the capsules in the correct orientation, so that the liquid adding mechanism can add liquid to the capsules in the correct orientation.

[0013] The waste removing mechanism can further include a waste removing frame, and the waste removing frame is provided with a suction port which can suck the capsules.

[0014] The technical scheme is adopted, the waste removing frame is connected with a pneumatic component, so that the waste capsules can be removed by the suction force generated by the suction port, and the waste removing is realized.

[0015] The full-automatic capsule processing equipment can be further provided with a cylinder connected with the reject frame, a clamping plate connected with the output end of the cylinder, a push rod connected with the clamping plate, and a thimble connected with the end of the push rod away from the clamping plate, wherein the thimble is distributed below the suction port.

[0016] According to the technical scheme, the cylinder drives the thimble to push the waste capsules towards the suction port through the clamping plate and the push rod, so that the waste capsules can be more accurately and effectively rejected, the working effectiveness and stability of the reject mechanism are improved, and the phenomenon of missed rejection is avoided.

[0017] The full-automatic capsule processing equipment can be further provided with a transfer device including a rotatable second turntable, a plurality of groups of second capsule conveying assemblies distributed on the outer periphery of the second turntable and arranged in the circumferential direction of the second turntable, wherein each second capsule conveying assembly includes at least two groups of capsule conveying frames, a layering driving mechanism connected with the at least two groups of capsule conveying frames and capable of controlling the at least two groups of capsule conveying frames to be stacked in sequence, and a plurality of groups of first capsule placing grooves are arranged on each group of capsule conveying frames, and the first capsule placing grooves on every two adjacent groups of capsule conveying frames can be communicated with each other after the at least two groups of capsule conveying frames are stacked in sequence by the layering driving mechanism.

[0018] According to the technical scheme, the capsule conveying efficiency can be greatly improved. Compared with the single-row conveying form of the prior art, the technical scheme can realize a single multi-row form, and by using the layering driving mechanism, the plurality of groups of capsule conveying frames can be stacked in each other when the at least two groups of capsule conveying frames are moved to the discharge position. By using the discharge top rod in the prior art, a plurality of layers of capsules can be discharged at one time, so that the production efficiency is improved, and the discharge top rod in the prior art does not need to be changed. The "communicable with each other" means that the positional relationship between the corresponding capsule placing grooves can achieve that the capsules can be moved from one group of capsule placing grooves to another group of capsule placing grooves.

[0019] The full-automatic capsule processing equipment can be further provided with at least two groups of capsule conveying frames including a first capsule conveying frame and a second capsule conveying frame, a layering driving mechanism including a first connecting rod connected with the first capsule conveying frame and arranged in a direction perpendicular to the axis of the second turntable, and a second connecting rod connected with the second capsule conveying frame and arranged in a direction parallel to the axis of the second turntable, a first linear bearing connected with the end of the first connecting rod away from the first capsule conveying frame, a first roller connected with the end of the second connecting rod away from the second capsule conveying frame, and a first base arranged below the second turntable, wherein the first base is provided with a first guide surface for the first roller to roll, and the first guide surface is provided with a plurality of first high points and a plurality of first low points.

[0020] Adopting the technical scheme, the first base is in a fixed form (i.e. without rotation or linear motion), the first capsule transport rack and the second capsule transport rack move simultaneously with the second turntable, at the same time, due to the gravity of the second capsule transport rack, the first roller always adheres to the first base, when the first roller moves to the first low point of the guide surface, the second capsule transport rack and the first capsule transport rack are in the same horizontal plane (this state is to facilitate the placement of the capsules after compression into the first capsule placement slot on the first capsule transport rack and the second capsule transport rack), then the first capsule transport rack and the second capsule transport rack continue to move with the second turntable, until the first roller moves to the first high point of the guide surface, the second capsule transport rack is at the upper end of the first capsule transport rack (but at this time, the second capsule transport rack and the capsule placement slot on the first capsule transport rack are not positionally corresponding), then according to the actual situation, when the second turntable drives the first capsule transport rack and the second capsule transport rack to move to the discharge port, the first connecting rod pushes the first capsule transport rack, until the capsule placement slots on every adjacent two groups of capsule transport racks on the first capsule transport rack and the second capsule transport rack can be mutually communicated, then the existing arrangement mechanism can push out the capsules, and a plurality of rows of capsules can be transported at one time; the improved layering transport mechanism can not only realize the multi-row transport function and greatly improve the production efficiency, but also has a clever design, the second capsule transport mechanism only needs to move with the second turntable to realize lifting, without additional driving sources such as air cylinders, and has a low cost; further, the first roller is used as a transmission part between the second connecting rod and the guide surface, the point contact form between the first roller and the guide surface has small friction resistance and will not cause jamming, so that the second capsule transport rack has good working stability.

[0021] The above-mentioned full-automatic capsule processing equipment can be further provided with: the second turntable is provided with a group of first guide holes corresponding to each group of first connecting rods and a group of second guide holes corresponding to each group of second connecting rods.

[0022] Adopting the technical scheme, the first guide holes are arranged on the second turntable, which facilitates the mutual penetration and assembly of the first connecting rod and the second turntable, the first connecting rod does not need to be installed outside the second turntable, the overall size is further reduced, further, the first guide holes can also guide the movement of the first connecting rod, improving the working stability of the first connecting rod; the second guide holes are arranged on the second turntable, which facilitates the mutual penetration and assembly of the second connecting rod and the second turntable, the second connecting rod does not need to be installed outside the second turntable, the overall size is further reduced, further, the second guide holes can also guide the movement of the second connecting rod, improving the working stability of the second connecting rod.

[0023] The above-mentioned full-automatic capsule processing equipment can be further provided with: a rubber pad is arranged in the first capsule placement slot.

[0024] By adopting the technical scheme, the rubber pad is arranged in the first capsule placing groove, on one hand, the limiting force of the capsule in the first capsule placing groove is increased, and the capsule is prevented from falling, and on the other hand, the rubber pad made of rubber material will not scratch the surface of the capsule, and the capsule is protected.

[0025] The full-automatic capsule processing equipment can be further provided with: the first capsule conveying and placing assembly comprises a third capsule conveying and placing frame and a fourth capsule conveying and placing frame, the third capsule conveying and placing frame is provided with a second capsule placing groove, and the fourth capsule conveying and placing frame is provided with a third capsule placing groove; the third capsule conveying and placing frame is connected with third connecting rods distributed in a direction perpendicular to the first rotating disc axis, the fourth capsule conveying and placing frame is connected with fourth connecting rods distributed in a direction parallel to the first rotating disc axis, the third connecting rod is connected with a second linear bearing at a distal end of the third capsule conveying and placing frame, the fourth connecting rod is connected with a second roller at a distal end of the fourth capsule conveying and placing frame, and a second base is arranged below the first rotating disc, the second base is provided with a second guide surface, and a plurality of groups of second high points and a plurality of groups of second low points are arranged on the second guide surface.

[0026] By reasonably distributing the arrangement sequence of the second low points and the second high points (which can be freely combined according to actual conditions), the relative positions of the third capsule conveying and placing frame and the fourth capsule conveying and placing frame can be changed. For example, after the first rotating disc receives the hard capsules transported from the first feeding mechanism, the hard capsule cap and the hard capsule body must be separated in order to add liquid, add soft capsules or pills, and in order to separate the capsule cap and the capsule body, the third capsule conveying and placing frame and the fourth capsule conveying and placing frame need to be separated upwards and downwards. When the third capsule conveying and placing frame and the fourth capsule conveying and placing frame move to the pressing mechanism, the third capsule conveying and placing frame and the fourth capsule conveying and placing frame can be changed into a stacked state, so that the pressing mechanism can press the capsule cap and the capsule body to realize preliminary pressing of the capsule. For another example, when the third capsule conveying and placing frame and the fourth capsule conveying and placing frame move to the rejection mechanism, since there are unqualified capsules, the third capsule conveying and placing frame and the fourth capsule conveying and placing frame cannot be kept in a stacked state, and need to be kept in a staggered or parallel state, so that the rejection can be better performed. Therefore, the above requirements can be realized by reasonably distributing the distribution positions of the second high points and the second low points.

[0027] The full-automatic capsule processing equipment can be further provided with: the capsule drying unit comprises a capsule conveying belt for circularly transporting capsules from the capsule filling unit to the capsule drying unit, and a plurality of groups of fourth capsule placing grooves are uniformly distributed on the capsule conveying belt, and the fourth capsule placing grooves are arranged in an inclined manner relative to the transportation direction of the capsule conveying belt.

[0028] Adopt the technical scheme, change the angle of the fourth capsule placing groove compared with the capsule conveying belt, make the fourth capsule placing groove in the inclined state, when the capsule is transported to the capsule conveying belt, due to the influence of various factors such as transportation rate, capsule self rolling rate, compared with the prior art capsule vertically arranged on the capsule conveying belt, the capsule is more easily dropped into the capsule placing groove, thereby reducing the capsule that cannot fall into the capsule placing groove, reducing the scrap rate of this part.

[0029] Wherein, the high points (first high point, second high point) and low points (first low point, second low point) mentioned in the foregoing are not simple point positions, but in order to reasonably express that the first guide surface and the second guide surface are not regular planes, there are higher positions (high points) and lower positions (low points), when the first roller and the second roller roll to different positions, the up-down positions of the second capsule transport and placement frame and the fourth capsule transport and placement frame will also change, so as to realize the switching between the stacked or non-stacked states of the first capsule transport and placement frame and the second capsule transport and placement frame, and the third capsule transport and placement frame and the fourth capsule transport and placement frame.

Detailed Implementation

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] like Figures 1 to 10 The fully automatic capsule processing equipment shown includes a machine body, with a capsule filling unit 1 at one longitudinal end and a capsule drying unit 3 at the other end. The capsule filling unit 1 and the capsule drying unit 3 are connected by a capsule sealing unit 2.

[0044] The capsule filling unit 1 comprises two groups of first material dropping mechanisms 11, a detection mechanism 12, two groups of liquid adding mechanisms 13, two groups of second material dropping mechanisms 14, a waste removing mechanism 15, a pressing mechanism 16, a transfer device 17 and a rotating disc mechanism 18, the first material dropping mechanisms 11, the detection mechanism 12, the liquid adding mechanisms 13, the second material dropping mechanisms 14, the waste removing mechanism 15, the pressing mechanism 16 and the transfer device 17 are sequentially connected through the rotating disc mechanism 18; the detection mechanism 12 is additionally arranged for detecting the capsules that cannot be filled with liquid, so that the liquid adding mechanisms 13 can add liquid to the capsules that can be filled with liquid, and then the waste removing mechanism 15 is used to remove the waste capsules, thereby solving the problem that the waste capsules cannot be detected in the prior art, avoiding that the liquid adding mechanisms 13 add liquid to the waste capsules, reducing waste, and also avoiding the generation of empty capsules, so that no empty capsules are generated after the capsules are processed by the device. The first material dropping mechanisms 11 are used for empty hard capsules, the liquid adding mechanisms 13 add liquid to the capsules, the second material dropping mechanisms 14 are used for transporting soft capsules or medicine such as pills and capsules that need to be added into the capsules, and then the capsules and the caps are pressed by the pressing mechanism 16 to press each other, so that the filling of the capsules is completed, and then the capsules are sealed by the capsule sealing unit 2, and finally the capsules are dried by the capsule drying mechanism.

[0045] The rotating disc mechanism 18 comprises a rotatable first rotating disc 181 and 12 groups of first capsule transferring assemblies 182 distributed on the outer periphery of the first rotating disc 181 and distributed in the circumferential direction of the first rotating disc 181; the rotating disc mechanism 18 adopts a rotating disc form and has high integration, so that the overall floor area can be minimized. The first capsule transferring assembly 182 comprises a third capsule transferring rack 1821 and a fourth capsule transferring rack 1822, the third capsule transferring rack 1821 is provided with a second capsule placing groove, and the fourth capsule transferring rack 1822 is provided with a third capsule placing groove; the third capsule transferring rack 1821 is connected with a third connecting rod 1823 distributed in the direction perpendicular to the axis of the first rotating disc 181, the fourth capsule transferring rack 1822 is connected with a fourth connecting rod 1824 distributed in the direction parallel to the axis of the first rotating disc 181, the third connecting rod 1823 is connected with a second linear bearing 1825 at the end away from the third capsule transferring rack 1822, the fourth connecting rod 1824 is connected with a second roller 1826 at the end away from the fourth capsule transferring rack 1822, and a second base 185 is arranged below the first rotating disc 181, the second base 185 is provided with a second guide surface 184, and the second guide surface 184 is provided with a group of second high points 1841 and a group of second low points 1842. By arranging the second guide surface 184 and the second high points 1841 and the second low points 1842 on the second guide surface 184, the relative positions of the third capsule transferring rack 1821 and the fourth capsule transferring rack 1822 can be changed.

[0046] The action principle of the rotating disc mechanism 18 is that the rotating disc mechanism 18 is sequentially provided with a hard capsule feeding station, a body cap separation station 183, a detection station, a liquid adding station, a soft capsule (or pill) feeding station, a scrap removing station, a pressing station and a transfer station along the effective rotating direction of the rotating disc mechanism 18. The first rotating disc can rotate along the above-mentioned stations by the existing driving source such as a servo motor and continuously rotate according to the above-mentioned rule. The first low points on the second guide surface are respectively arranged at the first capsule feeding station and the pressing mechanism 16, and the second guide surface is respectively provided with high points corresponding to the rest of the stations. When the first rotating disc drives a group of first capsule conveying assemblies to move to the hard capsule feeding station, the second roller rolls to the second low point, and the third connecting rod is in the state of not being stretched out. At this time, the third capsule conveying rack and the fourth capsule conveying rack are in the state of being stacked with each other, and the first feeding mechanism 11 can transport the hard capsules to the group of first capsule conveying assemblies at this time. Then the group of first capsule conveying assemblies moves to the body cap separation station 183, and at this time the second roller rolls to the second high point position. In this process, the third capsule conveying rack and the fourth capsule conveying rack are in the state of being separated, so that the separation of the capsule body cap is completed. Then the group of first capsule conveying assemblies moves through the detection station, the liquid adding station, the soft capsule (or pill) feeding station and the scrap removing station. At the liquid adding station, the soft capsule (or pill) feeding station and the scrap removing station, the second roller is still in the second high point position, the third connecting rod drives the third capsule conveying rack to stretch out towards the distance, so as to facilitate the liquid adding of the liquid adding mechanism 13, the feeding of the second feeding mechanism 14 and the scrap removing of the scrap removing mechanism. Then the group of first capsule conveying assemblies continues to move to the pressing station and the transfer station. In this process, the second roller is in the second low point position, and the third connecting rod drives the third capsule conveying rack to reset, so that the third capsule conveying rack and the fourth capsule conveying rack are in the state of being stacked with each other at the two stations, so as to facilitate the pressing of the pressing mechanism 16 on the cap and the body, and the transfer device receives the capsules transported from the rotating disc mechanism 18.

[0047] The detection mechanism 12 comprises a detection rack 121 and 16 groups of sensors 122 which are detachably and fixedly installed on the detection rack 121. When installed, only the sensors 122 need to be placed on the movement track of the first capsule conveying assembly 182. When a group of first capsule conveying assemblies 182 passes through this place, 16 groups of sensors 122 detect the capsules placed slots on the first capsule conveying assembly 182 respectively, and record the capsules with correct orientation, so as to facilitate the liquid adding of the liquid adding mechanism 13 on the correct capsules.

[0048] The waste removing mechanism 15 comprises a waste removing frame 151, and a suction port 152 for sucking the capsule is arranged on the upper portion of the waste removing frame 151. The waste removing frame 151 is connected with a pneumatic component, so that the waste capsule can be removed by the suction force generated by the suction port 152, thereby achieving the waste removing. The waste removing frame 151 is connected with a pneumatic cylinder 153, the output end of the pneumatic cylinder 153 is connected with a clamping plate 154, the clamping plate 154 is connected with a push rod 155, the end portion of the push rod 155 away from the clamping plate 154 is connected with a ejector pin 156, and the ejector pin 156 is distributed below the suction port 152. The pneumatic cylinder 153 drives the ejector pin 156 to push the waste capsule towards the suction port 152 through the clamping plate 154 and the push rod 155, so that the waste capsule can be more accurately and effectively removed, and the working effectiveness and stability of the waste removing mechanism 15 are improved, and the phenomenon of missing removal does not occur.

[0049] The transferring device 17 comprises a rotatable second rotating disc 171, four groups of second capsule transferring assemblies 172 distributed on the outer periphery of the second rotating disc 171 and distributed along the circumferential direction of the second rotating disc 171, and each second capsule transferring assembly 172 comprises two groups of capsule transferring frames, a stacking driving mechanism connected with the two groups of capsule transferring frames and capable of controlling the two groups of capsule transferring frames to be stacked in sequence. Sixteen first capsule placing grooves 1727 are arranged on each capsule transferring frame. The two groups of capsule transferring frames comprise a first capsule transferring frame 1721 and a second capsule transferring frame 1722. The stacking driving mechanism comprises a first connecting rod 1723 connected with the first capsule transferring frame 1721 and distributed along the direction perpendicular to the axis of the second rotating disc 171, and a second connecting rod 1724 connected with the second capsule transferring frame 1722 and distributed along the direction parallel to the axis of the second rotating disc 171. The end portion of the first connecting rod 1723 away from the first capsule transferring frame 1721 is connected with a first linear bearing 1725. The end portion of the second connecting rod 1724 away from the second capsule transferring frame 1722 is connected with a first roller 1726. The stacking driving mechanism comprises a first base 173 distributed below the second rotating disc 171, and the first base 173 is provided with a first guide surface 174 for the first roller 1726 to roll. The two ends of the first guide surface 174 are first high points 1741, and the middle portion of the first guide surface 174 is a first low point 1742. The second roller 1826 is used as a transmission component between the second connecting rod 1724 and the first guide surface 174, and the point contact form is adopted between the second roller 1826 and the first guide surface 174, so that the friction resistance is small and the jamming phenomenon does not occur, thereby improving the working stability of the second capsule transferring frame 1722.

[0050] The first base 173 is fixed (i.e. without rotation or linear motion), the first capsule transport rack 1721 and the second capsule transport rack 1722 move together with the second turntable 171. At the same time, due to the gravity of the second capsule transport rack 1722, the first roller 1726 always adheres to the first base 173. When the first roller 1726 moves to the first low point 1742 of the first guide surface 174, the second capsule transport rack 1722 and the first capsule transport rack 1721 are on the same horizontal plane (this state is to facilitate the placement of capsules into the first capsule placement slot 1727 on the first capsule transport rack 1721 and the second capsule transport rack 1722). Then the first capsule transport rack 1721 and the second capsule transport rack 1722 continue to move with the second turntable 171, until the first roller 1726 moves to the first high point 1741 of the first guide surface 174, the second capsule transport rack 1722 is on the upper end of the first capsule transport rack 1721 (but at this time the second capsule transport rack 1722 and the first capsule placement slot 1727 on the first capsule transport rack 1721 are not positionally corresponding). Then according to the actual situation, when the second turntable 171 drives the first capsule transport rack 1721 and the second capsule transport rack 1722 to move to the discharge port, the first connecting rod 1723 pushes the first capsule transport rack 1721, until the first capsule placement slot 1727 on every adjacent two groups of capsule transport racks on the first capsule transport rack 1721 and the second capsule transport rack 1722 can be mutually permeable. Then the existing arrangement mechanism is used to push out the capsules, which can realize the transportation of multiple rows of capsules at a time.

[0051] The second turntable 171 corresponds to each group of first connecting rods 1723 and is provided with a group of first guide holes 1711, and corresponds to each group of second connecting rods 1724 and is provided with a group of second guide holes 1712.

The fourth capsule placing grooves 311 arranged on the capsule conveying belt 31 are arranged in an inclined manner with respect to the transporting direction of the capsule conveying belt 31. By changing the angle of the fourth capsule placing grooves 311 with respect to the capsule conveying belt, the fourth capsule placing grooves 311 are arranged in an inclined state, and due to the influence of various factors such as the transporting speed and the rolling speed of the capsules, the capsules are more likely to fall into the fourth capsule placing grooves 311 compared with the capsules arranged vertically on the capsule conveying belt in the prior art, so that the capsules that cannot fall into the fourth capsule placing grooves 311 are reduced, and the waste rate of this part is reduced.

[0054] The working principle of the embodiment is as follows: the hard capsules are dropped, sorted and oriented by the first dropping mechanism 11; the hard capsules transported from the first dropping mechanism 11 are received by the rotating disc mechanism 18, and then the rotating disc mechanism 18 separates the capsule cap and the capsule body of the hard capsules; the hard capsules are detected by the detection mechanism, and the unqualified capsules are detected; then the rotating disc mechanism 18 continues to move the hard capsules until the liquid adding mechanism 13, the liquid adding mechanism 13 adds liquid into the separated capsule body; the whole capsule after adding liquid continues to move with the rotating disc mechanism 18 until the second dropping mechanism 14, the second dropping mechanism 14 injects the soft capsules or pills containing medicine into the capsule body; then the unqualified capsules detected by the detection mechanism are removed by the rejection mechanism, and the capsule body and the capsule cap of the hard capsules are pressed by the pressing mechanism 16, the hard capsules after pressing are transported to the capsule sealing unit 2 by the transfer device, the capsules after sealing are transported to the capsule drying unit 3 for drying, and finally the finished products are discharged.

[0055] The first dropping mechanism 11, the liquid adding mechanism 13, the second dropping mechanism 14, the pressing mechanism 16, the capsule sealing unit 2 and the capsule drying unit 3 are all prior art, which are well known to those skilled in the art, and will not be described herein.

[0056] The embodiment has the following advantages:

[0057] (I) Add detection mechanism 12, rejection mechanism 15, detect and reject the capsule that can not be filled with liquid, solve the problem that the existing technology can not detect the waste capsule, avoid the liquid adding mechanism 13 to add liquid to the waste capsule, reduce waste, also can avoid the production of empty capsules, so that the capsules processed by the device will not appear empty capsules.

[0058] (II) Design a new transfer device 17, realize single multi-row transportation form, and use the layering driving mechanism. When at least two groups of capsule transport racks move to the discharge position, the layering driving mechanism can make multiple groups of capsule transport racks stack with each other. The existing discharge ejector rod can discharge multiple layers of capsules at a time. Not only the production efficiency is improved, but also the existing discharge mechanism does not need to be changed.

[0059] (III) Set rubber pad 175 in the capsule placing groove. On the one hand, increase the limiting force of the capsule in the capsule placing groove to avoid the capsule from falling. On the other hand, the rubber pad 175 made of rubber material will not scratch the surface of the capsule, protecting the capsule.

[0060] (IV) Change the angle of the capsule placing groove compared to the capsule conveying belt to reduce the capsules that cannot fall into the capsule placing groove and reduce the waste rate of this part.

[0061] (V) The device as a whole has very high production efficiency.
