Description

Technical Field

[0001] The invention relates to the field of drug column air-drying and transportation, and in particular to a drug column air-drying production line and a turning mechanism and a transport mechanism thereof. Background Art

[0002] After the powder column is formed, the material is conveyed to the powder column fixed length shearing machine through a conveyor to be cut, and then conveyed to the production line of the powder drying workshop through a conveyor for drying to meet the process requirements of the next step. However, due to the high temperature and high pressure in the production process of the powder column (the temperature of the powder column after forming is generally 80-100°C), it is flammable and explosive. During the drying process, the traditional process requires personnel to carry the formed powder column to the powder drying rack in the powder drying workshop. The subsequent turning and carrying require manual participation. Once the powder column burns, there is a huge safety hazard when the amount of powder columns in the workshop is large, which endangers the life of the operator.

[0003] However, the existing automatic medicine drying workshop does not have the function of straightening the medicine column, and the structure of the medicine drying production line is relatively complex, and the medicine drying process is cumbersome. For example, Chinese utility model patent publication number CN219193672U discloses an automatic production line for drying solid medicine columns, which production line comprises a rotating medicine drying conveyor line (1), a stationary medicine drying conveyor line (2), a buffer conveyor line (3), a return plate conveyor line A (4), a cross-workshop conveying device (5), a tooling line changing manipulator (6), a medicine column line changing manipulator (7), a tooling (8), a lifting mechanism (9), and a return plate conveyor line B (10); the rotating medicine drying conveyor line (1) and the stationary medicine drying conveyor line (2) are arranged in the same workshop, arranged side by side in an S shape, and the head and tail are connected by a tooling line changing manipulator (6); the two medicine column line changing manipulators (7) are respectively connected to the two ends of the cross-workshop conveying device (5), so as to realize the non-straightening of the solid medicine column. During the conversion of the same workshop room, one of the medicine column line changing manipulators (7) is connected to the output end of the static medicine drying conveyor line (2), and the other medicine column line changing manipulator (7) is connected to the input end of the buffer conveyor line (3); the buffer conveyor line (3) is arranged in another workshop, arranged side by side in an S shape, and the head and tail are connected by the tooling line changing manipulator (6); the return tray conveyor line A (4) is located at the lower layer of the rotating medicine drying conveyor line (1) and the static medicine drying conveyor line (2), one end is connected to the tail end of the static medicine drying conveyor line (2) through a lifting mechanism (9), and the other end is connected to the head end of the rotating medicine drying conveyor line (1) through a lifting mechanism (9); the return tray conveyor line B (10) is located at the lower layer of the buffer conveyor line (3), arranged along the position of the buffer conveyor line (3), and the conveying direction is opposite to the buffer conveying direction. The head and tail are connected by a lifting mechanism (9) to realize the accumulation and circulation of the tray between the two layers of conveyor lines.

[0004] This patent adopts a continuous and automated medicine drying production line to achieve continuous and automated production of solid medicine drying, meet the needs of mass production, realize the separation of man and machine, effectively avoid the unsafe risk factors caused by human-material contact in production, and improve production safety. However, the medicine column in this patent needs to be transported between two workshops through a cross-workshop conveyor. The equipment structure is complex, and the head and tail of the conveyor line are connected by a tooling line changing robot. The robot transports the medicine column to the adjacent conveyor line, which is inefficient. The medicine drying conveyor line is divided into a rotating medicine drying conveyor line and a stationary medicine drying conveyor line. The medicine column can only be rotated on the rotating medicine drying conveyor line to achieve uniform medicine drying, which is prone to uneven medicine drying. In addition, the production line has no straightening function, and the medicine column cannot reach the next production workshop after the medicine drying is completed. Summary of the invention

[0005] In order to overcome the great safety risks of manual medicine drying in the above-mentioned background technology, and the problems that the existing automatic medicine drying production line has complex equipment structure, complex operation, uneven medicine drying, no straightening function, and the medicine column cannot reach the next production workshop after the medicine drying is completed, the present invention provides a medicine drying production line for the medicine column and its flipping mechanism and transfer mechanism, which can automatically dry the medicine, straighten, flip and transfer the medicine, and has the beneficial effects of high degree of automation, elimination of safety hazards, high medicine drying efficiency and high practical value.

[0006] The technical solution of the present invention is as follows:

[0007] A medicine column drying production line comprises a head transport line, a medicine drying mechanism and a tail transport line which are connected in sequence, wherein the head transport line is communicated with a discharge port of a medicine column fixed-length shearing machine, the medicine drying mechanism comprises a plurality of medicine drying transport lines which are arranged in sequence from high to low, the transport directions of adjacent medicine drying transport lines are opposite, and the discharge end of each medicine drying transport line delivers the medicine column to the feed end of the adjacent medicine drying transport line.

[0008] Preferably, the head transport line and the tail transport line respectively include a climbing conveyor, and the conveyor belt surface of the climbing conveyor has several rows of partitions evenly arranged along the conveying direction thereof, and each row of partitions is perpendicular to the conveying direction of the conveyor belt.

[0009] Further preferably, each row of partitions is divided into multiple sections, and the spacing distance between the partitions of adjacent sections ranges from 10 to 15 mm; baffles are also fixed to the edges of both sides of the conveyor belt surface.

[0010] Preferably, the medicine drying transport line includes a belt conveyor, and the conveyor belt of the belt conveyor includes an upper conveyor belt and a lower conveyor belt whose conveying surfaces are perpendicular to each other, and the angles between the upper conveyor belt and the lower conveyor belt and the horizontal plane are both 45°; the number of the medicine drying transport lines is 8-11; the transport directions of the head transport line and the tail transport line are both perpendicular to the transport direction of the medicine drying transport line.

[0011] Compared with the prior art, the above technical solution has the following beneficial effects:

[0012] (1) By setting up medicine-drying transport lines arranged in sequence from high to low, and the moving directions of adjacent medicine-drying transport lines are opposite, the medicine column can pass through each layer of the medicine-drying transport lines in sequence. During the long-term dynamic medicine-drying process, the moisture contained in the medicine column can be fully evaporated, and the medicine-drying transport lines can drive the medicine column to move automatically, thereby avoiding the problem of great safety risks in the manual medicine-drying method in the background technology.

[0013] (2) Two mutually perpendicular conveyor belts are arranged to transport the medicine column. During the transportation, the medicine column can be dried and automatically straightened and shaped under the squeezing action of the two conveyor belts. The shape of the medicine column after forming is more stable. The upper conveyor belt and the lower conveyor belt are perpendicular to each other, which can adapt to the medicine columns of different diameters for straightening. This solves the problem that the existing medicine drying production line in the background technology cannot achieve the straightening of the medicine column.

[0014] The present invention also provides a technical solution:

[0015] A turning mechanism for a medicine column drying production line comprises a head conveying line, a medicine drying mechanism and a tail conveying line which are connected in sequence, the head conveying line is communicated with a discharge port of a medicine column fixed-length shearing machine, the medicine drying mechanism comprises a plurality of medicine drying conveying lines which are arranged in sequence from high to low, the conveying directions of adjacent medicine drying conveying lines are opposite, and the discharge end of each medicine drying conveying line conveys the medicine column to the feed end of the adjacent medicine drying conveying line; the medicine drying conveying line comprises a belt conveyor, the conveyor belt of the belt conveyor comprises an upper conveyor belt and a lower conveyor belt whose conveying surfaces are perpendicular to each other; the discharge end of each medicine drying conveying line is arranged with a turning mechanism, the turning mechanism comprises a plurality of turning columns which are evenly arranged along the conveying direction of the medicine drying conveying line, the medicine column moves horizontally from the discharge end of the medicine drying conveying line to the surface of the turning column, the turning column turns downward, and the medicine column slides to the feed end of the medicine drying conveying line of the next layer.

[0016] Preferably, the tail of the upper conveyor belt extends forward beyond the lower conveyor belt, the flipping mechanism is arranged at the tail of the lower conveyor belt and the tail of the flipping mechanism is flush with the tail of the upper conveyor belt; the flipping columns are rollers, all the flipping columns are connected in series through a rotating shaft, the flipping columns are fixed vertically to the rotating shaft, the upper surfaces of all the flipping columns are on the same plane and are not higher than the extended surface of the lower conveyor belt of the medicine drying transport line; the cylinder controls the flipping of the flipping column, and photoelectric sensors are also provided on both sides above the flipping column, and the photoelectric sensors are electrically connected to the cylinder.

[0017] Preferably, a support plate is further provided under the turning column. When the turning column turns downward, the medicine column reaches the support plate from the movable end of the turning column and rolls down from the surface of the support plate to the next layer of medicine drying transportation line. A plurality of strip holes matching the turning columns are provided on the surface of the support plate along its length direction. When each turning column turns downward, it passes through the corresponding strip hole, and the length of the strip hole is less than the width of the support plate.

[0018] The beneficial effects of the above technical solution are:

[0019] (1) By using the cylinder to control the rotation axis to rotate downward, the turning column is driven to turn downward, and the medicine column rolls down from the turning column to the starting position of the next medicine drying transportation line. The next medicine drying transportation line continues to transport and straighten the medicine. Thus, the turning mechanism can send the medicine column to the feeding end of the conveyor belt of the next medicine drying transportation line, and the transportation cycle is repeated until the medicine column is sent to the tail transportation line;

[0020] (2) By setting a plurality of turning columns, the transition function of the drug column between adjacent drug drying and transport lines and the turning effect of the drug column can be realized, and the contact area of ​​the contact surface of the drug column in the process of moving forward on the surface of the turning mechanism can be reduced, and the scratches on the surface of the drug column caused by the excessive friction contact surface can be reduced. In addition, a self-rotating turning column is used, so that rolling friction is generated between the drug column and the turning column when moving, and the use of rolling friction instead of sliding friction can greatly reduce the damage to the surface of the drug column caused by excessive friction when moving forward;

[0021] (3) By arranging a support plate under the turning column, when the turning column turns downward, the medicine column can smoothly transition from the plate surface under the support plate to the next medicine drying transport line after leaving the turning column. The support plate can play a buffering and protective role for the medicine column when the adjacent medicine drying transport line is running.

[0022] A transfer mechanism for a drug column drying production line comprises a head transport line, a drug drying mechanism, a tail transport line and a transfer mechanism which are connected in sequence, wherein the head transport line is communicated with a discharge port of a drug column fixed-length shearing machine; the transfer mechanism comprises a positioning device, a transfer device and a transfer device, the drug column enters the positioning device from the discharge end of the tail transport line, and is transferred to the transfer device through the transfer device, and the transfer device circulates and transfers the drug column.

[0023] Preferably, the positioning device includes a placement trough, which is located below the discharge end of the tail transport line, and the medicine column slides from the discharge end of the tail transport line into the placement trough; the placement trough includes a row of parallel V-shaped frames, and the transport direction of the tail transport line is parallel to the bottom of the V-shaped frame; a push rod is provided on one side of the placement trough, and the push rod pushes the medicine column to the positioning point under the action of the cylinder, and the transfer device selects a grasping robot, which grasps the medicine column from the positioning point each time.

[0024] Further preferably, the transfer device includes a transfer track and a transfer cart, and the transfer cart moves back and forth on the transfer track under the action of a traction device; a transfer box is fixed on the transfer cart, and a grasping robot grasps the medicine column from a positioning point and transfers it to the transfer box; the transfer device is provided with two groups, which operate alternately.

[0025] The beneficial effects of the above technical solution are:

[0026] The medicine column enters the positioning device from the discharge port of the tail transport line and is transferred to the transfer device through the transfer device. The transfer device circulates and transfers the medicine column and sends it to the starting point of the next production workshop, solving the problem in the background technology that the medicine column cannot reach the next production workshop after the medicine drying is completed. The use of two sets of transfer devices to operate alternately can improve the transfer efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0035] Example 1: Figures 1 to 5 A medicine column drying production line shown in the figure includes a head transport line 1, a medicine drying mechanism 2 and a tail transport line 3 which are connected in sequence. The head transport line 1 is connected to the discharge port of a medicine column fixed-length shearing machine 11. Specifically, the feed end of the head transport line 1 extends below the discharge port of the medicine column fixed-length shearing machine 11, and the two overlap in the vertical direction, so that all medicine columns after shearing can fall from the discharge port of the medicine column fixed-length shearing machine 11 to the feed end of the head transport line 1, and be transported to the medicine drying structure through the head transport line 1. The medicine drying mechanism 2 includes a plurality of medicine drying transport lines 21 arranged in sequence from high to low. The medicine drying mechanism 2 is arranged in a stepped manner as a whole. The moving directions of adjacent medicine drying transport lines 21 are opposite. The discharge end of each medicine drying transport line 21 transfers the medicine column to the feed end of the adjacent medicine drying transport line 21. The medicine column can be transferred from bottom to top or from top to bottom in the medicine drying mechanism 2. In this embodiment, the medicine column is transferred from top to bottom, that is, the discharge end of the medicine drying transport line 21 of the upper layer transfers the medicine column to the feed end of the medicine drying transport line 21 of the next layer. This top-to-bottom transfer method is more conducive to designing a corresponding transfer structure and is more energy-efficient. By setting up medicine drying transport lines 21 arranged from high to low, and the moving directions of adjacent medicine drying transport lines 21 are opposite, the medicine column can pass through each layer of medicine drying transport lines 21 in sequence. During the long-term dynamic medicine drying process, the moisture contained in the medicine column can be fully evaporated, and the medicine drying transport lines 21 can drive the medicine column to move automatically, avoiding the problem of great safety risks in manual medicine drying.

[0036] Embodiment 2: Based on Embodiment 1, the head transport line 1 and the tail transport line 3 are optimally designed. The head transport line 1 and the tail transport line 3 respectively include a climbing conveyor. The main function of the climbing conveyor is to carry out large-angle and vertical transportation. It can transport materials within the inclination range of 0°-90°, including a conveyor belt, a transmission device, a roller, a support frame and an electrical control system. The feed end of the conveyor belt of the climbing conveyor of the head transport line 1 extends directly below the discharge port of the drug column fixed-length shearing machine 11. The conveyor belt surface of the climbing conveyor is evenly arranged with several rows of partitions 61 along its conveying direction, and the partitions 61 of each row are perpendicular to the conveying direction of the conveyor belt. The partitions 61 can be fixed to the conveyor belt surface by gluing, wherein each row of partitions 61 is divided into multiple sections, that is, each row of partitions 61 is divided into multiple sections with a certain spacing distance, and the spacing distance between adjacent sections of partitions 61 in each row ranges from 10 to 15 mm, so as to prevent the medicine column from falling out from the gap between adjacent sections of partitions 61 in each row. In this embodiment, each row of partitions 61 is divided into two sections and are respectively located on the left and right sides of the conveyor belt. By arranging partitions 61 on the conveyor belt surfaces of the climbing conveyors of the head transport line 1 and the tail transport line 3, the position of the medicine column on the conveyor belt surface can be limited to prevent the medicine column from sliding on the sloped conveyor belt surface. Dividing the partitions 61 into several sections can also reduce the weight of the partitions 61 and reduce the transportation pressure of the climbing conveyor. Furthermore, baffles 62 are fixed to the edges of both sides of the conveyor belt surface. The baffles 62 are arranged along the conveying direction of the conveyor belt to prevent the medicine columns from falling from both sides of the conveyor belt, thereby ensuring the safety of the transportation process.

[0037] Embodiment 3: Based on Embodiment 1, the medicine drying conveyor line 21 is optimally designed. The medicine drying conveyor line 21 is transported by a horizontally arranged belt conveyor. The belt conveyor is a mechanical device that conveys materials in a continuous manner by friction drive. It can be used to form a material conveying process from the initial feeding point to the final unloading point on a certain conveyor line. The belt conveyor includes a frame, a roller, a driving device, a bracket, a conveyor belt and other parts. In this embodiment, the belt conveyor uses a V-type conveyor. The driving device of the V-type conveyor includes a driving wheel, two vertically arranged driven wheels and a conveyor belt respectively sleeved on the driven wheels. The two driven wheels are respectively connected to gears. The driving wheel is coaxially connected to one of the gears, and the gear is toothed with the other gear. The driving wheel drives the gear connected to it to rotate, and the gear drives the other gear to rotate. Thus, one driving wheel can simultaneously drive the two driven wheels to rotate, and the two driven wheels drive the conveyor belt to move, and the conveying direction and conveying speed of the two conveyor belts are the same. The conveying surfaces of the two conveyor belts are connected perpendicularly to each other, that is, the angle between the conveying surfaces of the two conveyor belts is 90°, wherein the upper conveyor belt of the two conveyor belts is the upper conveyor belt 22, and the lower conveyor belt is the lower conveyor belt 23. In the medicine drying transport line 21, two mutually perpendicular conveyor belts are set to transport the medicine column. During the transportation process, the medicine column can be dried and automatically straightened and shaped under the squeezing action of the two conveyor belts. The shape of the medicine column after forming is more stable, and the upper conveyor belt 22 and the lower conveyor belt are perpendicular to each other, which can adapt to the straightening of medicine columns of different diameters. The angle between the upper conveyor belt 22 and the lower conveyor belt 23 of each layer of the medicine drying transport line 21 and the horizontal plane is 45°, so that when the medicine column is sent to the next layer of the medicine drying transport line 21, the medicine column can slide down smoothly on the surface of the upper conveyor belt 22.

[0038] Furthermore, the number of medicine drying transport lines 21 is 8-11, and 9 are selected in this embodiment, so that the medicine column can be fully dried without wasting too much medicine drying transport lines 21. The transport directions of the head transport line 1 and the tail transport line 3 are both perpendicular to the transport direction of the medicine drying transport line 21, and the feed end of the medicine drying transport line 21 located at the top (i.e., the medicine drying transport line 21 that the medicine column arrives at first) of all medicine drying transport lines 21 extends below the discharge end of the head transport line 1, and the medicine column can directly roll down from the terminal position of the conveyor belt of the head transport line 1 to the starting position of the conveyor belt of the medicine drying transport line 21; similarly, the discharge end of the medicine drying transport line 21 located at the bottom (i.e., the medicine drying transport line 21 that the medicine column arrives at last) of all medicine drying transport lines 21 is located above the feed end of the tail transport line 3, and the two overlap in the vertical direction, so that all medicine columns can roll down directly from the terminal position of the medicine drying transport line 21 to the starting position of the conveyor belt of the tail transport line 3.

[0039] Example 4: Based on the above examples, this example proposes a flipping mechanism for a medicine column drying production line. The discharge end of the conveyor belt of each medicine drying transport line 21 is connected to a flipping mechanism 4, through which the medicine column can be sent to the feed end of the conveyor belt of the medicine drying transport line 21 of the next layer, and the medicine column is transported in a cycle until it is sent to the tail transport line 3. The turning mechanism 4 includes a plurality of turning columns 41 evenly arranged along the transport direction of the medicine drying transport line 21, and each turning column 41 is perpendicular to the transport direction of the medicine drying transport line 21. The medicine column moves horizontally from the discharge end of the conveyor belt of the medicine drying transport line 21 to the upper surface of the turning column 41. When the turning column 41 turns downward, the medicine column slides to the feed end of the conveyor belt of the next layer of medicine drying transport line 21. By setting a plurality of turning columns 41, the transition function of the medicine column between adjacent medicine drying transport lines 21 and the turning effect of the medicine column are realized, and the contact area of ​​the contact surface of the medicine column in the process of moving forward on the surface of the turning mechanism 4 can be reduced, thereby reducing the scratches on the surface of the medicine column caused by the excessive friction contact surface.

[0040] The tail (i.e., the outlet end) of the upper conveyor belt 22 of the medicine drying transport line 21 extends forward beyond the lower conveyor belt 23, and the flipping mechanism 4 is arranged on one side of the tail of the lower conveyor belt 23, and the tail of the flipping mechanism 4 is flush with the tail of the upper conveyor belt 22 (i.e., on the same vertical plane). This design method allows the upper conveyor belt 22 to continue to drive the medicine column to move forward on the flipping mechanism 4, and cooperate with the flipping mechanism 4 to enable the medicine column to be transported to the next medicine drying transport line 21. The turning column 41 uses a roller, and the body of the roller can rotate around its central axis under the restriction of the support ears at both ends. The connecting ends of the turning column 41 are connected in series through the rotating shaft 42, and the movable end is extended outward. The turning column 41 is fixed vertically to the rotating shaft 42. The rotating shaft 42 is fixed on the frame below the conveyor belt and on the extension line of the connection point between the upper conveyor belt 22 and the lower conveyor belt 23. When the medicine column reaches the surface of the turning column 41, it continues to move forward on the surface of the turning column 41 under the action of the upper conveyor belt 22, and at the same time drives the turning column 41 to rotate. When the medicine column moves, rolling friction is generated between the medicine column and the turning column 41. Using rolling friction instead of sliding friction can greatly reduce the damage to the surface of the medicine column due to excessive friction when moving forward.

[0041] The upper surfaces of all the turning columns 41 are on the same plane and not higher than the extended surface of the conveying surface of the lower conveyor belt 23 of the medicine drying transport line 21, so as to prevent the medicine column from being unable to transition to the surface of the turning column 41. In this embodiment, the upper surface of the turning column 41 and the extended surface of the lower conveyor belt 23 are on the same plane, which is conducive to the smooth transition of the medicine column. The spacing distance between adjacent turning columns 41 and the spacing distance between the tail of the lower conveyor belt 23 and the nearest turning column 41 is 10 mm.

[0042] The rotating shaft 42 is driven by a cylinder, and photoelectric sensors 43 are also provided on both sides above the flip column 41. The photoelectric sensors 43 are electrically connected to the cylinder, and the output end of the piston rod of the cylinder is connected to the eccentric wheel mechanism, driving the eccentric wheel in the eccentric wheel mechanism to do reciprocating motion, thereby driving the rotating shaft 42 to rotate downward and rotate upward to reset. When the medicine column on the conveyor belt is transported to the flip column 41, the photoelectric sensor 43 senses that the medicine column has reached the flip mechanism 4, and then controls the cylinder to start. The cylinder controls the rotating shaft 42 to rotate downward through the eccentric wheel mechanism, driving the flip column 41 to flip downward, and the medicine column rolls down from the flip column 41 to the starting position of the next layer of the medicine drying transport line 21, and the next layer of the medicine drying transport line 21 continues to transport and straighten the medicine.

[0043] Embodiment 5: Based on the embodiment 4, a preferred design is performed, in which a support plate 44 is further provided under the turning column 41. When the turning column 41 turns downward, the medicine column reaches the support plate 44 from the movable end of the turning column 41, and rolls from the surface of the support plate 44 to the bottom of the upper conveyor belt 22 of the next medicine drying transport line 21. In the next medicine drying transport line (21), the edge of the movable end of each support plate 44 overlaps with the edge of the upper conveyor belt 22 of the next medicine drying transport line 21, so that all medicine columns can roll from the support plate 44 to the upper conveyor belt 22 of the next medicine drying transport line 21, thereby preventing the medicine columns from falling. A plurality of strip holes 45 are provided on the surface of the support plate 44 along its length direction, and the shape and size of the strip holes 45 are matched with the turning column 41. When each turning column 41 turns downward, it passes through the corresponding strip hole 45, wherein the length of the strip hole 45 is smaller than the width of the support plate 44, that is, after the medicine column leaves the turning column 41, it can smoothly transition from the plate surface at the bottom of the support plate 44 to the next layer of the medicine drying transport line 21, and the support plate 44 can play a buffering and protective role for the medicine column when the adjacent medicine drying transport line 21 is in operation.

[0044] Example 6: Based on the above examples, this example proposes a transfer mechanism for a medicine column drying production line, the transfer mechanism includes a positioning device, a transfer device and a transfer device, the medicine column enters the positioning device from the discharge port of the tail transport line 3, and is transferred to the transfer device through the transfer device, and the transfer device circulates and transfers the medicine column.

[0045] Specifically, the positioning device includes a placement groove 51, which is located below the discharge end of the tail transport line 3, and the medicine column slides from the discharge end of the tail transport line 3 into the placement groove 51. The placement groove 51 is a V-shaped groove structure as a whole, including a row of parallel V-shaped frames 52, the transportation direction of the tail transport line 3 is parallel to the bottom of the V-shaped frame 52, that is, the transportation direction of the tail transport line 3 is perpendicular to the length direction of the placement groove 51, and the medicine column falling from the discharge end of the tail transport line 3 slides along the side wall of the V-shaped frame 52 to the bottom of the placement groove 51, and is flattened on the bottom of the groove. A push rod 53 is provided on one side of the placement groove 51, one side of the push rod 53 is fixedly connected to the piston rod of the cylinder, the push rod 53 is parallel to the V-shaped frame 52, and is pushed along the length direction of the placement groove 51. Under the action of the cylinder, the push rod 53 pushes the medicine column to the positioning point at one end of the placement groove 51 uniformly, and the transfer device uses a grabbing robot 56, and the grabbing robot 56 grabs the medicine column from the positioning point each time.

[0046] Furthermore, the transfer device includes a transfer track 54 and a transfer trolley 55. The transfer trolley 55 moves back and forth on the transfer track 54 under the action of the traction device. The transfer trolley 55 is connected to the traction rope of the traction device. The traction device controls the transfer trolley 55 to move back and forth between the starting point and the end point of the transfer track 54 through the traction rope. The starting point of the transfer track 54 is set next to the positioning device, and the grabbing robot 56 is arranged between the positioning device and the starting point of the transfer track 54. The end point of the transfer track 54 is located at the starting point of the next production workshop. A transfer box 57 is fixed on the transfer trolley 55, and the grabbing robot 56 grabs and transfers the drug column from the positioning point to the transfer box 57. The transfer device is provided with two groups, namely, two groups of transfer tracks 54 and transfer carts 55, which operate alternately, and each transfer cart 55 moves back and forth on the corresponding transfer track 54. When the grasping robot 56 fills the transfer box 57 of one of the transfer carts 55 with the medicine column, the traction device controls the transfer cart 55 to start transporting it to the end point of the transfer track 54. At the same time, the grasping robot 56 transfers the medicine column to the transfer box 57 of another transfer cart 55. When the previous transfer cart 55 returns to the starting point after unloading, the next cart starts transporting it to the end point of the corresponding transfer track 54 after being filled. The two transfer carts 55 operate alternately and continuously, and transfer is uninterrupted, thereby improving transportation efficiency and production efficiency.

[0047] The medicine drying production line of the present invention, when in operation, the medicine columns sheared from the discharge port of the medicine column fixed-length shearing machine 11 fall into the conveyor belt of the head transport line 1, and the medicine columns move upward along the transport direction of the head transport line 1 to reach the discharge end and fall into the medicine drying transport line 21. Since the two conveyor belts of the medicine drying transport line 21 are perpendicular to each other, medicine columns of different diameters can be adaptively straightened, and the transport directions of adjacent medicine drying transport lines 21 are opposite and the turning mechanism 4 is used to realize the operation of medicine columns between adjacent medicine drying transport lines 21, so that the medicine columns can pass through each layer of the medicine drying transport line 21 in turn. When the medicine column reaches the surface of the turning column 41 of the turning mechanism 4, the upper conveyor belt 22 will continue to drive the medicine column forward, and the turning column 41 will rotate under the action of the rolling friction force with the medicine column, and cooperate with the upper conveyor belt 22 to transport the medicine column forward. When the photoelectric sensor 43 senses the medicine column reaching the turning mechanism 4, it controls the cylinder to start, and the cylinder drives the rotating shaft 42 to rotate downward, and the turning column 41 turns downward. The medicine column rolls downward from the turning column 41 to the support plate 44, and then rolls smoothly from the bottom of the support plate 44 to the upper conveyor belt 22 of the next layer of the medicine drying transportation line 21. At the same time, the turning column 41 passes through the bar hole 45 when rotating downward. When the cylinder is reset, it drives the turning column 41 to rotate upward and reset. When the medicine column reaches the last medicine drying transport line 21, it can reach the tail transport line 3 from the turning mechanism 4 at the discharge end of the medicine drying transport line 21, and then reach the placement groove 51 of the positioning device from the tail transport line 3. The push rod 53 then pushes the medicine column to the positioning point under the action of the cylinder. The grasping robot 56 grasps the medicine column from the positioning point each time and sends it to the transfer box 57 of the transfer cart 55. After the transfer box 57 is loaded, the transfer cart 55 sends the medicine column to the starting point of the next production workshop along the transfer track 54. The transfer device is provided with two groups, which can operate alternately to improve the transfer efficiency.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the technical solution concept of the present application, and these all belong to the protection scope of the present application.
