Description

Technical Field

[0001] This invention relates to the field of herb peeling machine technology, specifically to an intelligent herb peeling machine. Background Technology

[0002] Tablets and capsules are commonly packaged in PTP blister packs using a thermoforming machine. This blister packaging structure with aluminum foil offers many advantages to users, such as convenience, hygiene, isolation from air and humidity that could affect drug stability, optimized storage conditions, and the ability to be taken simply by gently squeezing from the back of the PTP blister pack. Currently, in hospitals and pharmacies, some medications, when used in large quantities, often require the removal of their outer packaging for easier access. However, manually removing the packaging is often time-consuming, labor-intensive, and inefficient, and can damage hands when removing large quantities of medication, failing to meet current medical needs. Therefore, automated medication removal machines have been developed. The existing automatic medicine peeling machines fall into two categories: the first type automatically adjusts the position of the claws, but requires manual feeding, and the adjustment method of the claws is limited to equidistant adjustment of the spacing between the medicine tablets in the medicine plate (i.e., it can only automatically adjust the spacing of the top tablets to be the same, and is not suitable for medicine plates with different spacing between the medicine tablets). The second type is automatic feeding, but when clamping the medicine plate, the position of the claws needs to be manually adjusted, and the number of claws needs to be manually adjusted to correspond to the number of rows of medicine tablets in the medicine plate, which cannot achieve a good automation effect. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, the objective of this invention is to provide an intelligent drug peeling machine with a high degree of automation and high drug peeling efficiency.

[0004] The objective of this invention is achieved through the following technical solutions:

[0005] The intelligent herb peeling machine includes a frame, on which are:

[0006] The feeding rack is inclined downward and can hold multiple medicine plates side by side along the feeding direction. The end of the feeding rack has an outlet.

[0007] The feed roller is located at the outlet of the feeder and can drive the medicine plate at the outlet to move along a downward inclined feeding path.

[0008] The drug dispensing mechanism includes a pressure shaft and a top shaft arranged opposite each other on both sides of the drug feeding path, and a pressure shaft driving mechanism. The pressure shaft is located diagonally above the top shaft, and the top shaft is provided with several top plates. Each top plate can move axially relative to the top shaft independently. The pressure shaft driving mechanism can drive the pressure shaft to rotate, thereby squeezing the passing drug plate and extruding the drug tablet through the cooperation of the pressure shaft and the top plates.

[0009] The measurement and positioning mechanism includes a measurement sensor, a measurement drive mechanism, and a display stand for placing static schematic medicine plates. The display stand is the same width as the feeding rack and is positioned opposite each other. The measurement drive mechanism can drive the measurement sensor to move along the width of the display stand and can measure the spacing between each row of medicine plates on the schematic medicine plate through the measurement sensor.

[0010] The paddle mechanism includes a paddle for moving the top piece circumferentially along the top axis, and a corresponding paddle drive mechanism.

[0011] The controller connects the measuring sensor and the paddle mechanism, and can control the paddle mechanism according to the measurement data of the measuring sensor so that the distribution of each top piece is such that there is a top piece on each side of each row of pills with equal spacing.

[0012] As a preferred technical solution, at least one side of the feeding rack is provided with a first width adjustment plate that can adjust the width of the feeding rack, and at least one side of the display rack is also provided with a second width adjustment plate that can adjust the width of the display rack.

[0013] As a preferred technical solution, the first width adjustment plate is provided with a guide hole that penetrates its side. The guide hole is an elongated hole arranged along the length direction of the first width adjustment plate. The feeding rack also includes a feeding push rod and a feeding drive mechanism. The feeding push rod passes through the guide hole and can move along the guide hole under the drive of the feeding drive mechanism, so that the feeding push rod pushes the medicine plate located in the feeding rack to move towards the outlet direction.

[0014] As a preferred technical solution, the feeding rack further includes a rack, a material box guide rail that can move along the long side of the rack, an adjusting plate gear that can mesh with the rack, and an adjusting plate drive module that can drive the material box guide rail to move or drive the adjusting plate gear to rotate. The rack is horizontally fixed at the bottom of the feeding rack, the lower end of the material box guide rail is connected to the adjusting plate gear, and the upper end of the material box guide rail is fixedly connected to the first width adjusting plate.

[0015] As a preferred technical solution, the display stand is located in front of the feeding rack. The display stand is provided with a slot for vertically inserting and fixing the schematic medicine plate. The bottom of the slot is hollow. The measuring sensor is located below the display stand, and the sensing opening of the measuring sensor faces upward and is used to detect the protrusion of the medicine tablet on the medicine plate.

[0016] As a preferred technical solution, the feeding shaft, the pressure shaft, and the top shaft are all parallel to each other and parallel to the medicine plate moving along the medicine feeding path, so that the medicine plate will not be displaced in the width direction during the conveying process of the feeding rack and the feeding path.

[0017] As a preferred technical solution, the end of the top shaft is connected to a swing arm, and the top of the swing arm is elastically connected to the frame through an elastic element. The frame also includes a shaft loosening mechanism, which includes a cam, a drive gear, a shaft loosening drive module, and a driven main wheel meshing with the drive gear. The driven gear is fixedly connected to the cam, and the output shaft of the shaft loosening drive module is connected to the drive gear, thereby driving the driven gear to rotate and the cam to rotate, so that the cam contacts the swing arm and realizes the movement of the top shaft.

[0018] As a preferred technical solution, the measuring drive mechanism includes a lead screw, a lead screw drive mechanism for driving the lead screw to rotate, and a slider disposed on the lead screw. The measuring sensor and the pawl mechanism are both located on the slider. The pawl mechanism includes a pawl guide rail. The pawl drive mechanism can drive the pawl to move toward the top shaft axis, thereby causing the pawl to move forward and insert between each top plate or withdraw from between each top plate.

[0019] As a preferred technical solution, the feeding rack is tilted from back to front and downward, and the feeding path of the medicine plate is tilted from front to back and downward.

[0020] Compared with existing technologies, the intelligent medicine peeling machine provided by this patent has the following advantages: ① It uses a measuring sensor to measure the spacing between the medicine tablets on the indicated medicine plate, and controls the peeling mechanism according to the measured quantity so that each row of medicine tablets has a top piece with equal spacing on both sides. The distance is moderate, which facilitates the interaction force between the pressure shaft and the top piece, thereby achieving the optimal placement of the top piece. This prevents the medicine tablets in the medicine plate from being crushed due to the pressure shaft and the top piece being too close to the medicine tablets, and also prevents the medicine tablets from being peeled off due to insufficient pressure because the top piece is too far away from the medicine tablets. It has a high degree of intelligence and automation, and is suitable for medicine plates with different spacing between medicine tablets, with high applicability; ② The pressure shaft is located at an angle above the top shaft. The first feature is that it prevents the peeled tablets from falling downwards onto the top shaft and top plate due to gravity, thus avoiding tablet contamination. It also prevents the powder generated during tablet peeling from falling onto the top shaft and top plate, which would accumulate over time and form contaminants. Furthermore, it prevents tablets from getting stuck in the position where the top plate and hinge shaft are connected, thus affecting the rotation of the hinge shaft and top plate and reducing the chance of tablet jamming. The second feature is that the medicine plate moves along the end outlet of the feeding frame and is driven by the feeding rubber shaft to move along the medicine feeding path to the space between the pressure shaft and the top plate for peeling, realizing automatic feeding without manual operation, high peeling efficiency, and high degree of automation. The third feature is that it automatically adjusts the position of the top plate and automatically feeds, resulting in a high degree of automation in the peeling machine.

[0029] like Figure 1-5As shown, this embodiment provides an intelligent medicine peeling machine, including a frame 1, a feeding rack 2 on the frame 1, the feeding rack 2 is inclined downward and can place multiple medicine plates A side by side along the feeding direction, and the end of the feeding rack 2 has an outlet; a feeding shaft 11 is located at the outlet of the feeding rack 2 and can drive the medicine plates A at the outlet to move along an inclined downward feeding path; a medicine peeling mechanism 3, including a top shaft 32 arranged opposite to each other on both sides of the feeding path, and a pressure shaft drive mechanism, wherein the pressure shaft 31 is located obliquely above the top shaft 32, the top shaft 32 is provided with a plurality of top plates 33, each of the top plates 33 can move axially relative to the top shaft 32 independently, the pressure shaft drive mechanism can drive the pressure shaft 31 to rotate, thereby squeezing the passing medicine plates A and extruding the medicine tablets through the cooperation of the pressure shaft 31 and the top plates 33. The device includes a measurement and positioning mechanism 4, comprising a measurement sensor 41, a measurement drive mechanism 42, and a display stand 43 for placing a static schematic medicine plate B. The display stand 43 is the same width as the feeding rack 2 and is positioned opposite each other. The measurement drive mechanism 42 can drive the measurement sensor 41 to move along the width direction of the display stand 43 and can measure the spacing between each row of medicine plates on the schematic medicine plate B through the measurement sensor 41. The device includes a paddle mechanism 5, comprising a paddle 51 for moving the top piece 33 circumferentially along the top shaft 32, and a corresponding paddle drive mechanism 53. The device is connected to the measurement sensor 41 and the device 5 and can control the device 5 according to the measurement data of the measurement sensor 41 so that the distribution of each top piece 33 is such that there is one top piece 33 with equal spacing on both sides of each row of medicine plates.

[0030] In this embodiment, a measuring sensor 41 is used to measure the spacing between the tablets on the schematic medicine plate B. Based on the measured quantity, the dispensing mechanism 5 is controlled so that each column of tablets has a top piece 33 with equal spacing on both sides. The distance is moderate, which facilitates the interaction force between the pressure shaft 31 and the top piece 33, thereby achieving the optimal placement of the top piece 33. This prevents the tablets in medicine plate A from being damaged by the pressure shaft 31 and the top piece 33 due to the top piece 33 being too close to the tablets in medicine plate A. It also prevents the tablets from being unsuccessfully dispensed due to insufficient pressure because the top piece 33 is too far from the tablets in medicine plate A. This method is highly intelligent and automated, and is suitable for medicine plates with different tablet spacing, making it highly applicable. The pressure shaft 31 is located diagonally above the top shaft 32, preventing the peeled tablets from falling downwards onto the top shaft 32 and top plate 33 due to gravity, thus avoiding tablet contamination. It also prevents powder generated during tablet peeling from falling onto the top shaft 32 and top plate 33, which could accumulate and form contaminants over time. Furthermore, it prevents tablets from getting stuck in the connection between the top plate 33 and the hinge shaft, thus reducing the chance of tablet jamming. The medicine plate A moves along the end outlet of the feed rack 2 and is driven by the feed shaft 11 to move along the feeding path between the pressure shaft 31 and top plate 33 for peeling, achieving automatic feeding without manual operation, high peeling efficiency, and a high degree of automation. The automatic adjustment of the top plate 33 position and automatic feeding contribute to the high degree of automation of the peeling machine.

[0031] In a preferred embodiment, at least one side of the feeding rack 2 is provided with a first width adjustment plate 21 that can adjust the width of the feeding rack 2, and at least one side of the display rack 43 is also provided with a second width adjustment plate 431 that can adjust the width of the display rack 43.

[0032] In a preferred embodiment, the first width adjustment plate 21 is provided with a guide hole 211 penetrating its side. The guide hole 211 is an elongated hole arranged along the length direction of the first width adjustment plate 21. The feeding rack 2 also includes a feeding push rod 212 and a feeding drive mechanism 213. The feeding push rod 212 passes through the guide hole 211 and can move along the guide hole 211 under the drive of the feeding drive mechanism 213, so that the feeding push rod 212 pushes the medicine plate A located in the feeding rack 2 to move toward the outlet direction.

[0033] In a preferred embodiment, the feeding rack 2 further includes a rack, a material box guide rail that can move along the long side of the rack, an adjusting plate gear that can mesh with the rack, and an adjusting plate drive module that can drive the material box guide rail to move or drive the adjusting plate gear to rotate. The rack is horizontally fixed at the bottom of the feeding rack 2. In this embodiment, there are two first width adjusting plates 21 arranged on the left and right. One first width adjusting plate 21 is fixedly connected to the frame 1. The lower end of the material box guide rail is rotatably connected to the adjusting plate gear. The adjusting plate gear rotates and drives the material box guide rail to move. The upper end of the material box guide rail is fixedly connected to the other first width adjusting plate 21.

[0034] In a preferred embodiment, the display rack 43 is located in front of the feeding rack 2. The display rack 43 is used to place the schematic medicine plate B. The display rack 43 is provided with a slot 433 for vertically inserting and fixing the schematic medicine plate B. The bottom of the slot 433 is hollow. The measuring sensor 41 is located below the display rack 43, and the sensing opening of the measuring sensor 41 faces upward and is used to detect the protrusion of the medicine tablet on the medicine plate A.

[0035] The display stand 43 also includes an adjustment shaft 432 and a nut 434. The adjustment shaft 432 is horizontally positioned and fixedly connected to the frame 1. The second width adjustment plate 431 is movably connected to the adjustment shaft 432. A slot 433 is located within the second width adjustment plate 431, with the opening of the slot 433 facing upwards to facilitate the insertion of the medicine plate B. There are two second width adjustment plates 431, one on the left and one on the right, and each second width adjustment plate 431 can be engaged with the left and right sides of the medicine plate A respectively. Each second width adjustment plate 431 has a screw hole, and the nut 434 engages with the screw hole to securely connect the second width adjustment plate 431 to the adjustment shaft 432.

[0036] In a preferred embodiment, the feeding shaft 11, the pressure shaft 31, and the top shaft 32 are all parallel to each other and parallel to the medicine plate A that moves along the medicine feeding path, so that the medicine plate A will not be displaced in the width direction during the conveying process of the feeding rack and the feeding path.

[0037] In a preferred embodiment, the end of the top shaft 32 is connected to a swing arm 321, and the top of the swing arm 321 is elastically connected to the frame 1 via an elastic element 322. The frame 1 also includes a shaft loosening mechanism, which includes a camshaft 323 fixed to the frame 1, a cam 324 fixed to the camshaft 323, a drive gear 325, a shaft loosening drive module 326, and a driven gear 327 meshing with the drive gear 325. The driven gear 327 is fixedly connected to the camshaft 323. The output shaft of the slack shaft drive module 326 is connected to the drive gear 325, which in turn drives the driven gear 327 to rotate and the cam 324 to rotate. Due to the change in the diameter of the cam 324, when the cam 324 rotates and pushes the rocker arm 321 upward, causing the rocker arm 321 to move upward, the top shaft 32 moves upward, and the elastic element 322 is compressed. When the cam 324 rotates and causes the rocker arm 321 to move downward under the elastic force of the elastic element 322, the top shaft 32 moves downward.

[0038] The top of the swing arm 321 is provided with a vertically arranged positioning pin 328, and the lower end of the elastic element 322 is sleeved on the positioning pin 328 to position the direction of the up and down elastic force of the elastic element 322.

A paddle drive mechanism 53 is connected to the paddle 51 and can drive the paddle 51 to move toward the axis of the top shaft 32, thereby causing the paddle 51 to move forward and insert between each top piece 33 or withdraw from each top piece 33. When the paddle 51 is inserted between each top piece 33, according to the data detected by the measuring sensor 41, the controller controls the lead screw 421 to rotate and drives the slider 422 to move, so that the paddle 51 moves and drives the top piece 33 to move along the axial direction of the top shaft 32 to a predetermined position. Then, the paddle drive mechanism 53 drives the paddle 51 to withdraw from each top piece 33, and the next top piece 33 moves under the control of the controller.
