Description

Technical Field

[0001] The invention belongs to the technical field of picking and packaging Chinese herbal medicines, and in particular relates to an automatic picking and packaging device for bulk Chinese herbal medicines. Background Art

[0002] At present, the fully automatic medicine picking devices commonly used in major hospitals are limited to picking up boxed and bagged Chinese medicine preparations, and there is no equipment for picking up bulk granular Chinese herbal medicines at home and abroad. The picking and packaging of bulk granular Chinese herbal medicines have always been done manually. At present, there are the following technical defects in manual picking of herbs:

[0003] 1. Large errors in sub-packaging affect the efficacy of the medicine. Manual medicine picking is to weigh the total amount of each medicine in the prescription with a beam scale, and then distribute it into several small portions according to experience. The amount of medicine in each portion is estimated by the naked eye and controlled by fingers, which leads to large errors and even greater cumulative errors. Generally, each prescription contains about 20 kinds of medicines, and each medicine is divided into 5 to 7 portions. The error in the distribution of each medicine is calculated based on the weight of 150g to 200g per dose. The error of a single medicine package is more than 20g, which affects the efficacy of the medicine, delays the condition, and causes certain economic losses to the patient.

[0004] 2. Low work efficiency. When a person is energetic, he or she will pick up 5 to 7 doses for one prescription. When 20 kinds of medicines are used, the total weight of each medicine is weighed and distributed into 5 to 7 portions. After the 20 kinds of medicines are distributed, they are put into medicine bags. If one person operates each prescription, it will take at least 15 minutes. As people's working hours get longer and their physical strength and energy decrease, the time to pick up the medicine will be even longer.

[0005] 3. The cost of picking up medicines is high. For example, in a small hospital, based on an average of 150 prescriptions per day, if the prescriptions are concentrated, it will take about 6 people to pick up the medicines, and the annual labor wages will be more than 200,000 yuan. And with the annual increase in labor costs, the company's employment costs will also rise year by year.

[0006] In summary, the existing manual picking and packaging method of herbs has low batching efficiency, large human errors, high labor intensity for workers, and high production costs for enterprises. Therefore, it is a technical problem that people in this field need to solve urgently to study and design an automatic picking and packaging device for bulk granular Chinese herbal medicines to replace manual picking of Chinese herbal medicines, so as to achieve the purpose of fast, small errors, and saving labor costs.

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the present invention. It is obvious that the described embodiments are only some exemplary specific implementation methods of the present invention and are not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any technician in this field without departing from the concept and principle of the present invention should fall within the scope of protection of the present invention.

[0047] Example 1

[0048] See also Figure 1-3 In the figure, the automatic picking and packaging equipment for bulk Chinese herbal medicines of the present invention includes a main trolley 1 and a medicine bag rack trolley 2 that move longitudinally and reciprocatingly, a medicine cartridge 3, a medicine bag rack 4, a horizontal circular turntable 5 and its rotating shaft 6 and a rotating drive device 7, a material baffle 8, a buffer hopper 9, a weighing hopper 10, and an electrical control system, etc.

[0049] The medicine bag rack trolley is arranged on the main trolley frame 1-1 in the same direction. There are multiple medicine cartridges, six of which are shown in the figure. They are arranged in a line vertically and suspended above the main trolley through the centering frame pull rod 14. There are multiple medicine bag racks, seven of which are shown in the figure. They are arranged in a line vertically and arranged on the traveling frame 2-1 of the medicine bag rack trolley. A horizontal circular turntable and a material dispenser are respectively arranged under each medicine cartridge. The lower part of the medicine cartridge is the receiving port, and the material dispenser is a material dispensing baffle fixed at the lower edge of the medicine cartridge port (see Figure 6 ). The buffer hopper and the weighing hopper are stacked up and down and are located between the horizontal circular turntable drop port and the upper and lower medicine bag racks.

[0050] In the above, the arrangement direction of the cartridge and the reciprocating direction of the main trolley are designated as longitudinal, and the layout direction of the bag rack is in the same direction as the reciprocating direction of the bag rack trolley and the main trolley. The front of the horizontal circular turntable is designated as the drop port. In addition, a closed cover can be added around the lower opening of the cartridge and the connection position of the horizontal turntable to collect dust. An integral bracket is provided between the cartridge and the main trolley, and no matter how many sets are combined, they are all provided on this stepped integral bracket.

[0051] The purpose of adding a buffer hopper and a weighing hopper in this embodiment is that, under the premise that the horizontal circular turntable keeps unloading, when the amount of herbs in the weighing hopper is close to the set number, the buffer hopper closes and reduces the amount. When the weighing hopper reaches the set number, the buffer hopper is completely closed. After the weighing hopper discharges the materials, it closes and the buffer hopper opens again; thereby, accurate picking and packaging of each dose of medicine can be achieved. The horizontal circular turntable cooperates with the material dispenser to achieve directional material dropping; each horizontal circular turntable shares a set of rotary drive devices, which can move back and forth with the main trolley, and drive each horizontal circular turntable in succession in a certain order, thereby achieving automatic picking and packaging of Chinese herbal medicines. This simplifies the structure and reduces the manufacturing cost.

[0052] The facility consists of a fully automatic trolley (i.e., an intelligent robot, including a main trolley and a medicine bag rack trolley) and a row of multiple Chinese herbal medicine tubes, forming a set of automatic picking and packaging process facilities for Chinese herbal medicines. Multiple Chinese herbal medicine tubes are arranged in a straight line with a walking track underneath. When working, the main trolley and the medicine bag rack trolley are controlled by an electrical control system to move back and forth longitudinally, and the relative positions of the drop openings of each horizontal circular turntable and the entrance of the buffer hopper, the outlet of the weighing hopper and the openings of each medicine bag on the medicine bag rack are adjusted successively, so as to realize the automatic picking and packaging of Chinese herbal medicines.

[0053] Example 2

[0054] See also Figure 4-5 , the structure of this embodiment is similar to that of embodiment 1, and the same numbers in the figure represent the same meanings. The difference is that in this embodiment, the rotation drive device 7 includes an active friction disk 7-1 and a passive friction disk 7-2 arranged up and down, a vertically arranged rotating main shaft 7-3 and its rotation drive mechanism, and a lifting mechanism.

[0055] The rotating drive mechanism is a stepper motor 7-4 for driving, and the lifting mechanism is a servo electric cylinder 7-5. The driving motor and the electric cylinder are arranged in the base of the main trolley, and the power output end of the driving motor is connected to the rotating main shaft, and the other end of the rotating main shaft is connected to the active friction disk. The passive friction disk is located below the horizontal circular turntable and is arranged at the end of the rotating shaft where the horizontal circular turntable is located. The active friction disk, the rotating main shaft and the driving motor are connected in sequence and then installed on the electric cylinder as a whole.

[0056] The active friction disc, rotating spindle, driving motor and electric cylinder form a set. When working, the electric cylinder drives the active friction disc, rotating spindle and driving motor to vertically lift and lower as a whole, so that the active friction disc and the passive friction disc are in contact or separated; under the action of the driving motor, the rotating spindle drives the active friction disc to rotate, and after the active friction disc and the passive friction disc are in contact and subjected to force, the passive friction disc is driven to rotate, and as the active friction disc and the passive friction disc are in contact or separated, the horizontal circular turntable is rotated or stopped.

[0057] Furthermore, the active friction disc 7-1 may include a rotating coupling disc 7-1-1, a friction pad 7-1-2 and a magnet 7-1-3. The friction pad is connected to the top of the rotating coupling disc, and the magnet is arranged at the center of the top of the rotating coupling disc. The rotating main shaft is rotatably supported on the main trolley frame 1-1 through the main shaft centering sleeve 7-6.

[0058] Example 3

[0059] See also Figure 1-3 In the figure, the structure of this embodiment is similar to that of Embodiment 2, and the same numbers in the figure represent the same meanings. The difference is that in this embodiment, the main trolley 1 / medicine bag rack trolley 2 includes a frame 1-1 / traveling frame 2-1, wheels and a traveling drive device. The main trolley / medicine bag rack trolley cooperates with the corresponding track 11 to achieve reciprocating movement. A material surface detector 12 is provided on the cartridge. A material shifting rod 13 is provided in the cartridge, and the material shifting rod is fixed on the rotating shaft where the horizontal circular turntable is located. The cache hopper and the weighing hopper share a bracket and are fixed on the main trolley frame. A weighing sensor (not shown in the figure) is provided on the weighing hopper, and the discharge ports of the cache hopper and the weighing hopper are respectively provided with electromagnetic rod controls (not shown in the figure).

[0060] This embodiment adds a material surface detection and alarm device to detect the material surface and alarm in time to prevent the Chinese herbal medicine in the medicine cartridge from being insufficient and affecting production; or the Chinese herbal medicine in the medicine cartridge has fallen out and the equipment is idling and consuming energy. The purpose of adding a material shifting rod is that Chinese herbal medicine is basically a fiber component with a small specific gravity and large differences. It is easy for it to fall unevenly or even not fall at all in a medicine cartridge with a smaller capacity. In order to solve the problem of normal material discharge, a material shifting rod is set on the main shaft of the horizontal circular turntable. The cache hopper and the weighing hopper share a bracket, which is fixed on the main trolley of the intelligent robot. The structure is relatively simple and compact, and the production cost is low.

[0061] Example 4

[0062] See also Figure 7 In the figure, the structure of this embodiment is similar to that of Embodiment 3, and the same numbers in the figure represent the same meanings. The difference is that in this embodiment, the power units used to drive the rotating main shaft, the reciprocating movement of the main trolley and the reciprocating movement of the medicine bag rack trolley are all stepper motors, and are stepper motor 1, stepper motor 2, and stepper motor 3 respectively.

[0063] The electrical control system includes a human-machine interface, a PLC controller, and a stepper driver electrically connected to each stepper motor, and a servo controller electrically connected to a servo electric cylinder. Each stepper driver, servo controller, and electromagnetic rods provided on the outlets of the buffer hopper and the weighing hopper, a weighing sensor provided on the weighing hopper, and a material surface detector provided in each cartridge are electrically connected to the PLC controller respectively. The human-machine interface is in communication connection with the PLC controller.

[0064] The specific working process is as follows:

[0065] See also Figure 1-7 For example, when the doctor prescribes 7 doses of medicine, the fully automatic main trolley (intelligent robot) installed under the medicine barrels arranged in a row goes to the bottom of the medicine barrel No. 1 according to the sequence of the Chinese herbal medicine numbers in the prescription, and the electric cylinder installed on the main trolley is started to lift the stepper motor together with the connected rotating main shaft and the active friction disk upward by about 20mm, until the active friction disk is in close contact with the passive friction disk and is subjected to the force of the magnetic suction, and the stepper motor 1 installed on the base of the main trolley is started to drive the active friction disk and the passive friction disk, which can drive the horizontal circular turntable installed at the bottom of the medicine hopper to rotate; the scattered granular herbs naturally accumulated on the horizontal circular turntable fall from the edge just in front of the horizontal circular turntable under the action of the material baffle fixed in the space between the lower edge of the barrel and the horizontal circular turntable, and the herbs in the prescription Each kind of herb falls continuously on the horizontal circular turntable according to the total amount of 7 pairs. At this time, the buffer hopper is open and the lower mouth of the weighing hopper is closed. The medicine falls into the weighing hopper controlled by the weighing sensor. When the weight of the medicine is close to the set quantity of each pair, the direct-acting electromagnetic rod closes the buffer hopper and opens the lower mouth of the weighing hopper while the horizontal circular turntable is working continuously, and the herb falls into the first medicine bag of the walking medicine bag rack trolley set below and then closes it again. At the same time, the medicine bag rack trolley moves forward one medicine bag rack position, and the buffer hopper opens and the herb falls into the weighing hopper. A reciprocating cycle is formed from the buffer hopper, weighing hopper, and medicine bag rack moving forward one position until the total amount of the first herb in the prescription is packaged according to the amount of 7 pairs of medicine; the control of the last dose of medicine is completed by deceleration of the stepper motor. The electric cylinder drops about 20 mm, the active friction disc and the passive friction disc separate, and the fully automatic main trolley (intelligent robot) runs to the bottom of the next herbal tube and starts to work in the previous mode until all the herbs in the prescription are packaged into the prescription according to the quantity. The operator takes the medicine bag out of the medicine bag rack and enters the automatic picking and packaging of the next prescription according to the instructions.

[0066] The types of herbs used in Chinese herbal medicine clinics vary according to the size of the specialist and comprehensive medical care, ranging from about 100 to about 200. In order to reduce the investment in facilities, the length of the herbal medicine clinic can be as long as possible. The herbal medicine cylinders can be arranged in a row of about 30 according to the pharmacological compatibility prescription. There is an automatic trolley (intelligent robot) under the row of cylinders, and a walking track. The three parts are a set of facilities. The hospital can configure the required number of sets according to its own medication dosage. In order to avoid the operation being affected by electrical failure, each user can be equipped with an additional automatic trolley (intelligent robot) as a spare, which can be replaced at any time when there is a failure.

[0067] In terms of accurate quantity requirements for herbal prescriptions, in order to reduce errors in the dosage of each individual medicine, pharmacies are required to purchase herbs with particle sizes below 10mm based on different specific gravities to reduce quantity errors. This issue is resolved through negotiation between the pharmacy and the supplier of medicinal materials.

[0068] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referenced to each other.

[0069] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Many modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the utility model. Therefore, the present invention shall not be limited to the embodiments shown herein, but shall conform to the widest scope consistent with the principles and novel features disclosed herein.
