Description

Technical Field

[0001] The invention relates to the technical field of position switching equipment for traditional Chinese medicine boxes, and in particular to a multi-layer upper and lower medicine box switching device. Background Art

[0002] In the field of traditional Chinese medicine, due to the wide variety and specifications of Chinese medicinal materials, Chinese medicinal slices, or Chinese patent medicines (up to thousands of kinds), and each Chinese medicinal material, Chinese medicinal slice, or Chinese patent medicine needs to be stored in a separate storage space, resulting in thousands of densely packed medicine boxes neatly arranged around the traditional Chinese medicine pharmacy. When the staff adjusts the Chinese medicine prescription, they first need to memorize the prescription content and the location of the medicine boxes of each medicinal material in the pharmacy, and then identify, compare, match, take and put, weigh, take and put the excess medicinal materials back into the medicine box, and take the insufficient amount again. Repeat the above operations until the prescription adjustment is completed (up to dozens of times to complete the adjustment of a single Chinese medicine prescription). Based on the many defects existing in the current traditional Chinese medicine pharmacies, we have produced a medicine box and a three-dimensional medicine or medicinal material warehouse (referred to as a three-dimensional medicine warehouse). After the medicine boxes are stacked and placed on the shelves of the three-dimensional medicine warehouse, the bottom of the medicine boxes are suspended in the air, and each medicine box is provided with an identifier or a unique identification mark, which can be quickly picked up and placed and accurately placed when the automatic picking equipment is used. During the medication process, it is convenient for the picking and placing mechanism to grab the medicine box and place it on the conveyor belt and then move forward to the operating area of ​​the medicine picker to grab the medicinal materials. After the medicine box is grabbed, it is transported to the corresponding shelf again by the conveyor belt and can also be put back to the original position by the picking and placing mechanism.

[0003] However, due to the wide variety and specifications of medicinal materials, the commonly used main medicinal materials are generally placed on the shelves close to the operating table, while some auxiliary medicinal materials are placed in the empty position far away from the operating table, and they can be retrieved when needed. If the medicine box shelf is close to the medicine picking personnel, the shelf and the operating table can be directly connected by a reversible conveyor belt to achieve rapid supply and return of the medicine box. Generally, an operating table only needs to be equipped with 3-4 conveyor belts to effectively and quickly supply and switch medicinal materials, thereby avoiding the untimely delivery of medicinal materials. When the medicine box shelf is a certain distance away from the operating table, if a two-way movable conveyor belt is used, and the number of conveyor belts is small, it will seriously affect the transportation of the medicine box. Efficiency, there are too many conveyor belts and they cannot be placed, and when multiple operating tables are side by side, it is impossible to supply medicinal materials with medicinal effects through a forward and reverse conveyor belt. Therefore, it is necessary to use a feeding conveyor belt from the shelf to the operating table area and a return conveyor belt that transports the medicine boxes that have been grabbed to the corresponding shelf again to effectively ensure the back and forth movement of the medicine boxes. In order to reduce the occupied space, the two conveyor belts are generally set up in upper and lower layers. No matter how close the operating table where the operator grabs the medicine is to the conveyor belt, since the feeding conveyor belt and the return conveyor belt are in a continuous rotation process, if the required medicine box cannot be taken out from the conveyor belt in time, it is easy to cause the medicine box to be over-supplied.

[0004] Based on the above problems existing in the transportation process of medicine boxes between shelves and operating tables, it is necessary to design a switching mechanism that can automatically separate the medicine boxes from the feeding conveyor belt in time during supply and then move them to the operating table to be grabbed, and can automatically move the grabbed medicine boxes to the return conveyor belt again.

[0005] At the same time, although the existing shelves and conveyor belts have solved the problem of automatic supply and storage of medicinal materials, in the actual process of prescription adjustment, they have high requirements on the quality of operators, high labor intensity, long adjustment cycle and low efficiency; poor traceability and difficult supervision; the working environment is dusty and harsh, resulting in high operator mobility, difficult to guarantee service quality, and high adjustment costs.

[0006] Therefore, after solving the storage and automatic supply of medicinal materials, it is also necessary to design a dispensing table that can automatically and quickly analyze and judge information such as the medicinal material ingredients in the supplied medicine box, the weight of the medicinal materials, and the content of the prescription, so as to solve the problems existing in the current dispensing process. Summary of the invention

[0031] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0032] Embodiment 1

[0033] like Figure 3 , Figure 5 and Figure 6As shown, a multi-layer upper and lower medicine box switching device includes a frame 303, a plurality of feeding belts 317 arranged on the frame 303, a feeding mechanism 305 arranged on the frame 303 for supplying medicine boxes to the feeding belts 317, and a discharging mechanism 304 for moving the medicine boxes on the feeding belts 317 to a specified position, the frame 303 is provided with a first control mechanism 318 for controlling the feeding belts 317 up and down, the first control mechanism 318 includes a slide rail 333 arranged on the frame 303 for connecting the feeding belts 317, a The third driver 319 on the frame 303 drives the feeding belt 317 on the slide rail 333 up and down. The feeding belt 317 is connected to the frame 303 by sliding along the slide rail 333 through the third driver 319. After the medicine box on the feeding belt 317 supplied by the feeding mechanism 305 grabs the medicinal materials, the feeding belt 317 is moved to the discharging mechanism 304 to deliver the medicine box through the first control mechanism 318. The power is transmitted between the third driver 319 and the connecting seat 324 through a transmission chain.

[0034] In actual operation, the feeding mechanism 305 can be directly connected to the medicine box shelf or to the conveyor belt, and the discharging mechanism 304 is generally connected to the conveyor belt. When the feeding mechanism 305 is directly connected to the medicine box shelf, the shelf is generally close to the operating table and can move back and forth quickly. When the medicine box is transported back and forth, generally only one medicine box is transported back and forth, and the feeding mechanism 305 realizes the functions of simultaneous feeding and discharging. When the medicine box on the feeding mechanism 305 only moves to the feeding belt 317, one end of it is connected to the feeding conveyor belt, which generally transports uncommon auxiliary medicinal materials. During operation, the medicine box on the medicine box shelf or the feeding conveyor belt is obtained by the feeding mechanism 305 and then cached and waited. When the feeding belt 317 needs to supply medicinal materials to the operator The material is then transported to the feed belt 317 by the feeding mechanism 305 and then to the designated position by the feeding mechanism 317 to wait for the grabbing of the medicinal materials. When the operator has finished grabbing the medicinal materials in the medicine box, the height position of the feeding mechanism 317 is adjusted by the first control mechanism 318 to align the feeding mechanism 317 with the discharging mechanism 304. The feeding mechanism 317 then transports the material back to the discharging mechanism 304 and then moves to the return conveyor belt to reset the medicine box. During the entire operation, the frame 303 is equipped with a plurality of feeding belts 317 for transporting the medicine boxes to be grabbed to the operating table and returning the grabbed medicine boxes to wait for resupply. Each feeding belt 317 can work independently, which is more flexible and can The operator on the operating table can grab the medicinal materials in time, and the supply efficiency of the medicinal materials is higher. When the medicine box is transferred between the shelf 303 and the feeding belt 317, the feeding mechanism 305 can be used as a transfer waiting area for the medicine box. After the medicine box is timely obtained from the conveyor belt by the feeding mechanism 305, it can be obtained from the feeding mechanism 305 when the feeding belt 317 needs to supply the medicine box. For the medicine box that has been grabbed on the feeding belt 317, the first control mechanism 318 can switch the position after moving the entire feeding belt 317 up and down, so that the medicine box is transported back by the feeding belt 317 and enters the discharging mechanism 304, and then moves to the return conveyor belt through the discharging mechanism 304, so that the medicine box to be picked up can be timely taken from the supply After being obtained from the material conveyor belt, it moves to the operating table to wait for grabbing, and the grabbed medicine box can be automatically moved to the return material conveyor belt for transmission again. The feeding conveyor belt and the return material conveyor belt do not need to stop frequently, thereby solving the problems of untimely supply and over-supply of medicine boxes when the medicine boxes are transported by the conveyor belt. Fewer personnel are required, and the requirements for personnel quality are lower, which effectively reduces personnel costs and reduces personnel mobility. The operation difficulty is low, the labor intensity is low, the adjustment cycle is short and the efficiency is high. When the height of the feeding belt 317 is controlled by the first control mechanism 318, the feeding belt 317 is slidably connected to the slide rail 333 on the frame 303 through the slider, and the third driver 319 and the feeding belt 317 transmit power through the transmission chain.When the third driver 319 rotates forward and reverse, the feeding belt 317 can be directly driven to move along the slide rail 333 through the transmission chain, and the moving position can be controlled by the position sensor, which is easier to operate. The third driver 319 preferably uses a servo motor, which is more convenient in system control, has a simple structure, and has a low production cost.

[0035] Preferably, the feeding belt 317 includes a connecting seat 324 slidably mounted on the slide rail 333, two parallel transmission belts 326 mounted on the connecting seat 324, and a driving mechanism 325 mounted on the connecting seat 324 for driving the transmission belt 326 to run forward and reversely. The transmission belt 326 is driven by the forward and reverse rotation of the driving mechanism 325 to move the medicine box in different directions.

[0036] In the process of moving the medicine box back and forth by the feeding belt 317, the feeding belt 317 is installed on the slide rail 333 through the connecting seat 324, and the two parallel transmission belts 326 are driven to rotate by the forward and reverse driving of the driving mechanism 325, so that the medicine box placed on the two parallel transmission belts 326 can be moved. The transmission belts 326 are two and arranged in parallel, which can make the medicine box stable during the movement.

[0037] Furthermore, the driving mechanism 325 includes a second driver 329 and at least two transmission wheels 327 arranged on the connecting seat 324 to rotate the transmission belt 326. The connecting seat 324 is also provided with a plurality of tensioning wheels 328 for adjusting the tension of the transmission belt 326.

[0038] When the transmission belt 326 is rotated by the driving mechanism 325, the two ends of the transmission belt 326 are positioned and rotated by the transmission wheel 327, and the two transmission belts 326 are driven to rotate by the second driver 329 at the same time, which has lower cost. A tensioning wheel 328 is provided between the second driver 329 and the transmission wheel 327, which can adjust the tightness of the transmission belt 326. Its simplest structure is to install a transmission wheel 327 at each end of the two transmission belts 326. The second driver 329 adopts a servo motor, and a rotating shaft is driven to rotate by the second driver 329. A driving wheel is installed at each end of the rotating shaft. The transmission belts 326 on both sides are driven to rotate by the driving wheels, and a tensioning wheel 328 is pressed on both sides of the driving wheel. The tensioning wheel 328 can achieve the tensioning effect and also change the running trajectory of the transmission belt 326.

[0039] Furthermore, a medicine box weighing platform 314 is provided between the two transmission belts 326, and a height adjustment mechanism 320 is provided between the medicine box weighing platform 314 and the connecting seat 324. After the medicine box weighing platform 314 is raised by the height adjustment mechanism 320, it is separated from the feeding belt 317 and weighed.

[0040] A medicine box weighing platform 314 that can be extended and retracted by a height adjustment mechanism 320 is also installed between the two transmission belts 326. Since the transmission belts 326 are two and arranged in parallel, the bottom of the medicine box has a hollow area, which can facilitate the placement and extension of the medicine box weighing platform 314. The medicine box placed on the upper end of the medicine box weighing platform 314 has better stability. When the medicine box is transported to the top of the medicine box weighing platform 314 by the feeding belt 317, the medicine box weighing platform 314 is moved upward by the height adjustment mechanism 320 to hold up the medicine box, thereby The medicines in the medicine box are weighed, and the information obtained by weighing is displayed through the medicine box information display 307. Since an identification code is attached to the medicine box, after combining with the sensor, the display content of the medicine box information display 307 includes basic information such as the current medicine name and the weight of the medicine box, and also has real-time display of information on the reduced weight, so as to facilitate quick calculation. When the medicine is taken out, you can know how much weight has been taken, which makes it more convenient and quick to calculate the weight of the medicine in the prescription, and the support stability of the medicine box is also higher.

[0041] Furthermore, the height adjustment mechanism 320 includes a first driver 321 arranged on the connecting seat 324, a lifting frame 322 arranged at the bottom of the medicine box weighing platform 314, and a cam mechanism 332 arranged between the first driver 321 and the lifting frame 322. The medicine box weighing platform 314 realizes the lifting and lowering of the lifting frame 322 by driving the cam mechanism 332 to rotate through the first driver 321; the cam mechanism 332 includes a connecting block 330 arranged on the rotating axis of the first driver 321, a driving wheel 331 arranged on the connecting block 330, and a connecting hole 323 arranged on the lifting frame 322, and the driving wheel 331 is located in the connecting hole 323.

[0042] When the medicine box weighing platform 314 is lifted and lowered by the height adjustment mechanism 320, the cam mechanism 332 can be driven to rotate by the first driver 321, so that the lifting frame 322 can be driven to lift and lower by the cam mechanism 332, thereby realizing the lifting and lowering control of the medicine box weighing platform 314. The structure is simple and convenient, the operation is flexible, and the up and down height adjustment is stable, the control accuracy is high, and the production cost is low. Moreover, when the first driver 321 and the lifting frame 322 are connected by the cam mechanism 332, a connecting block 330 equipped with a driving wheel 331 is used as a cam on the first driver 321, and a connecting block 330 on the bottom of the lifting frame 322 is used as a cam. A connecting hole 323 is opened to connect with the driving wheel 331. The axis of the driving wheel 331 is staggered with the rotating axis of the first driver 321 through the connecting block 330. When the first driver 321 rotates, the driving wheel 331 can drive the lifting frame 322 to control the height. The lifting frame 322 is composed of two guide rods installed at the bottom of the medicine box weighing platform 314 and a connecting rod located at the bottom of the two guide rods. The connecting hole 323 is located in the connecting rod. A guide sleeve is provided between the guide rod and the connecting seat 324. When the lifting frame 322 is moved up and down, it slides up and down in the guide sleeve through the guide rod. The first driver 321 adopts a servo motor.

[0043] At the same time, the feeding mechanism 305 includes a first mounting frame 338 arranged on the frame 303, two parallel feeding belts 337 arranged on the first mounting frame 338, and a feeding motor 339 arranged on the first mounting frame 338 to drive the feeding belt 337; the discharging mechanism 304 includes a second mounting frame 335 arranged on the frame 303, two parallel discharging belts 336 arranged on the second mounting frame 335, and a discharging motor 334 arranged on the second mounting frame 335 to drive the discharging belt 336.

[0044] In the process of moving the medicine box from a shelf or conveyor belt to the feeding belt 317 through the feeding mechanism 305, one end of the feeding mechanism 305 is fixed to the frame 303 through the first mounting frame 338, and the other end extends into the running track of the medicine box. When the medicine box enters the feeding belt 337, the feeding belt 337 is driven to move by the feeding motor 339, thereby achieving the purpose of feeding. When the medicine box needs to be moved out of the feeding belt 317, the operation can be achieved by simply moving the medicine box to the discharging belt 336 through the feeding belt 317 and continuing to move forward. The feeding motor 339 and the discharging motor 334 generally use forward and reverse motors or servo motors. The position of the medicine box and the start of each motor can be controlled by a position sensor.

[0045] Furthermore, the frame 303 is provided with a third control mechanism 302 and a second control mechanism 343 for controlling the up and down movement of the feeding mechanism 305 and the discharging mechanism 304 respectively, and the medicine box is picked up or put back by the third control mechanism 302 and the second control mechanism 343.

[0046] As for the movement of the medicine box, when the shelf is a certain distance away from the operator area, it is currently moved in a circular motion through a roller conveyor belt. Therefore, in order to quickly switch the medicine box between the feeding mechanism 305 and the discharging mechanism 304 and the conveyor belt, a third control mechanism 302 and a second control mechanism 343 are respectively installed on the frame 303 to control the up and down movement of the feeding mechanism 305 and the discharging mechanism 304. One end of the feeding belt 337 and the discharging belt 336 extends between the rollers of the two conveyor belts. When the medicine box needs to move on the conveyor belt, the feeding mechanism 305 and the discharging mechanism 304 are lowered by the third control mechanism 302 and the second control mechanism 343 so that their contact surface is lower than the working surface of the roller. When the medicine box needs to move on the feeding mechanism 305 and the discharging mechanism 304, the feeding mechanism 305 and the discharging mechanism 304 are raised by the third control mechanism 302 and the second control mechanism 343, so that the bottom surface of the medicine box is higher than the roller. The operation is flexible and convenient, and the trajectory switching of the medicine box is simple.

[0047] Furthermore, the third control mechanism 302 includes a connecting shaft 341 that connects the various feeding mechanisms 305 in series, a third slide 342 arranged at both ends of the connecting shaft, and a fourth driver 340 arranged on the frame 303 to slide the third slide 342 up and down, and the second control mechanism 343 includes a connecting shaft that connects the various discharging mechanisms 304 in series, a second slide 344 arranged at both ends of the connecting shaft, and a fifth driver 345 arranged on the frame 303 to slide the second slide 344 up and down.

[0048] The feeding mechanism 305 and the discharging mechanism 304 are connected in series through a connecting shaft 341 in the shape of a "", and the fourth driver 340 and the fifth driver 345 are respectively located on both sides of the frame 303, and the two ends of the connecting shaft 341 are connected to the transmission chain through a transfer block. When the feeding mechanism 305 and the discharging mechanism 304 need to be moved up and down, the height can be adjusted by controlling the direction of the transmission chain through their respective drivers. The operation is simple, the height adjustment is easy, and the cost and power consumption are lower. The fourth driver 340 and the fifth driver 345 both use forward and reverse motors or servo motors.

[0049] Furthermore, the feeding mechanism 305 and the discharging mechanism 304 are arranged in upper and lower layers, and the upper end of the feeding mechanism 305 is further provided with a feeding mechanism 305 with one end fixed on the frame 303. The topmost feeding mechanism 305 is directly connected to the common medicine shelf, thereby ensuring that the common medicine box can be quickly moved to the feeding belt 317 for picking medicine at the first time.

[0051] like Figures 1 to 6 As shown, an improvement is made on the basis of the first embodiment, in that the frame 303 is further provided with a plurality of picking windows 315 for separately picking up medicines from each medicine box supplied by the feeding belt 317, a total weighing table 301 for weighing the taken out medicines, a main display 308 provided on the frame 303 and a plurality of medicine box information displays 307 for separately displaying the medicine box information in each channel, and a control console 312 for controlling the functions of each mechanism, so that a new dispensing table or operating table is formed after the operation table for picking up medicines is combined with the frame, the medicine boxes in the picking windows 315 are supplied and returned by the feeding belt 317, the picking windows 315 are used to manually grab the medicines in the medicine boxes supplied by the feeding belt 317, and the manually grabbed medicines are put into the total weighing table 301 for weighing, and each picking window 315 is provided with an induction alarm device 306, and an alarm signal is sent through the induction alarm device 306 when an object enters the picking window 315 that cannot grab the medicines.

[0052] In actual use, a plurality of material taking windows 315 are installed side by side on the frame 303, each of which is equipped with an induction alarm device 306, and each material taking window 315 corresponds to a feeding belt 317 for supplying medicine boxes and a medicine box information display 307 for displaying the information of the medicine boxes respectively. The frame 303 is also provided with a main display 308 for retrieving and displaying the prescription, a total weighing table 301 for displaying the weight of all the medicines that have been taken, and a control console 312 for controlling various functions of the multi-channel dispensing table. The medicine boxes required in the prescription are supplied to the material taking window 315 through the feeding belt 317 for picking up the medicines and resetting the medicine boxes that have finished picking up the medicines. When the prescription to be picked up is displayed on the main display 308, the feeding belt 317 is used to feed the medicine boxes to the material taking window 315. Belt 317 supplies the medicine in the prescription to the material picking window 315 to be picked up, and displays the basic information of the medicine in the current material picking window 315 through the medicine box information display 307, and the medicine dispensing frame used to store the picked up medicine is placed on the total weighing table 301. When the medicine that has been weight-checked by the medicine box weighing table 314 is compared with the weight increase of the total weighing table 301 again, the weight of the medicine can be confirmed for a second time to avoid the problem of incorrect proportion of the medicine due to equipment error, effectively ensuring the accuracy of each pharmacy. The operator picks up the medicine from the corresponding material picking window 315. When picking up the medicine, if the hand reaches into the correct material picking window 315, the induction alarm device 306 will not generate an alarm signal. If the wrong The material taking window 315 senses the alarm device 306 to sound an alarm. When the medicine in the medicine box is taken out, it is transmitted again through the feeding belt 317 and sent into the medicine box where the medicine has not been taken. Since the multi-channel dispensing table has multiple feeding belts 317 and material taking windows 315 that can be controlled separately, when the multi-channel dispensing table (operating table) grabs the medicine on the prescription, there are multiple medicine boxes to be taken, which makes the efficiency of picking medicine better and the waiting time for the supply of medicine boxes shorter. At the same time, when the medicine box enters each material taking window 315, the system can automatically identify the information of the medicine in the medicine box and directly display it through each medicine box information display 307. The display content of the medicine box information display 307 includes the current drug name and the basic information such as the weight of the medicine box. In addition to the information, it also has the function of real-time display of information on reduced weight, the current operation priority level of the medicine box, the name of the medicine in the medicine box, the code, the picture of the medicine, the weight to be taken, the actual weight taken, special requirements and other information. It is no longer necessary to manually identify the basic information of the medicine, the medicine accuracy is higher, and it is not easy to make mistakes when grabbing. The information of the prescription can be displayed through the main display 308, which is more convenient for the management of the prescription. The display content of the main display 308 generally includes the basic information of the prescription and one or more of the information such as the grabbed medicine, the currently grabbed medicine or the ungrabbed medicine, and the display content of the medicine box information display 307 generally includes the current medicine name and one or more of the information such as the medicine box weight, the medicine weight, the reduced weight, etc.A medicine dispensing frame is generally placed on the total weighing table 301. When the medicine in the medicine box is grabbed and placed in the medicine dispensing frame, the weight of the grabbed medicine can be directly displayed through the total weighing table 301, and there is no need to perform separate weighing processing during the grabbing of medicines, especially when the display content of the medicine box information display 307 includes the reduced weight. By comparing the two, it can be accurately determined whether the grabbed amount of medicine is incorrect. Function buttons for different operations are provided on the control console 312. The grabbed medicine can be turned over and transmitted outward through the control switch on the corresponding feeding belt 317, so as to facilitate the supply of new medicine boxes. Since the multi-channel dispensing table forms a medicine box channel through a material collection window 315 and a feeding belt 317, Moreover, each multi-channel dispensing table has multiple channels. In order to prevent the operator from reaching into the material taking window 315 that is not currently used to take medicine to take medicine during the dispensing process, a sensing alarm device 306 is installed on each material taking window 315. When an object enters the material taking window 315 that cannot take medicine, an alarm signal can be sent through the sensing alarm device 306 to remind the operator of the operating error. When the material taking window 315 is designed to be open, it can also prevent foreign objects from falling into the material taking window 315 and causing damage to the equipment. During the entire operation process, the medicine box is automatically supplied and returned, and there is no need for manual handling of the medicine box, so the labor intensity is low. In addition, the use of a plurality of parallel material taking windows 315 structure can improve the supply efficiency of the medicine box. The rate is faster, and the efficiency of grabbing medicines in prescriptions is higher. During the whole operation process, a multi-channel dispensing table only needs one operator to complete the operation accurately, fewer personnel are required, and the requirements for personnel quality are lower, which effectively reduces personnel costs, reduces manual errors and losses, reduces personnel mobility, has low operating difficulty, and is quick to get started. The material picking window 315 and the feeding belt 317 are both 3-4 groups. When one person operates a multi-channel dispensing table, the supply speed and the time allocation for grabbing medicines are more reasonable. Since the dispensing table is generally installed next to the conveyor belt and multiple ones are placed in sequence, the dispensing table is connected to the conveyor belt through the feeding mechanism 305 and the discharging mechanism 304. When the medicine box shelves are far away from the dispensing table, the medicine box is generally passed through one or more groups. The medicine boxes on the feeding belt are intercepted and fed to the feeding belt 317 through the feeding mechanism 305. When some shelves of conventional medicinal materials are close to the feeding belt 317, one end of the feeding mechanism 305 can be directly extended into the medicine box shelf, and the feeding mechanism 305 can be directly moved back and forth through the forward and reverse rotation of the feeding mechanism 305, which effectively avoids the problem that commonly used medicinal materials also need to be frequently fed through the feeding conveyor belt. Generally, each dispensing table is equipped with a conventional medicinal material shelf. The medicinal materials on this shelf can be quickly fed through the feeding mechanism 305 that can be transported back and forth, which is more efficient when dispensing medicine.

[0053] Furthermore, the sensing alarm device 306 includes a grating 313 for monitoring the material picking window 315, a signal indicator light 316 for indicating the drug picking status of the material picking window 315 provided on the frame 303, and an alarm 310 provided on the frame 303. The grating 313 is used for real-time monitoring of whether an object enters the material picking window 315, the indicator light is used for prompting the operation priority of the material picking window 315, the current operation completion status and special situation alarm prompts, and the alarm 310 is used to send an alarm signal when an object enters the material picking window 315 where drug picking is not allowed.

[0054] When the material collection window 315 is monitored by the induction alarm device 306, the window area is covered by the grating 313. When a foreign object is inserted, the grating 313 will be blocked and the signal will be interrupted, thereby triggering the alarm 310 to sound an alarm. Monitoring through the grating 313 can also make the structure of the material collection window 315 open. When grabbing the medicine in the medicine box, you only need to open the lid on the upper end of the medicine box to grab it directly. In addition, in order to facilitate the operator to make a quick judgment, a signal indicator light 316 of the medicine collection status is also installed next to the material collection window 315. For example, a red light indicates a static medicine collection window, and a green light indicates a current medicine collection window, so that the material collection window 315 can be determined more quickly and conveniently.

[0055] Furthermore, an external device installation slot 311 is provided on the frame 303 , and a printer 309 is provided in the external device installation slot 311 .

[0056] Various external interfaces are provided on the external device installation slot 311, and a printer 309 is connected in the external device installation slot 311. After the prescription is captured, the prescription can be directly printed through the printer 309, and telephones, card readers and other equipment can also be installed, which makes the management of external devices more tidy.
