Description

Technical Field

[0001] The invention relates to the technical field of automatic medicine dispensing equipment, in particular to an automatic medicine adding device for box medicine with a buffer function. Background Art

[0002] The box medicine dispensing machine has many advantages such as safety, hygiene, high efficiency, and scientific management of medicines. The system can accurately record the number of medicines issued, the existing inventory, the expiration date of medicines, etc., which helps to realize information management. Therefore, it is currently widely accepted by tertiary hospitals in large and medium-sized cities in China. The box medicine automatic dispensing machine includes a dispensing mechanism and a dosing mechanism. According to the characteristics of the medicine box, there are currently two structures of the dosing mechanism: one dosing mechanism has a certain tilt angle, and the box medicine slides into the medicine slot of the dispensing mechanism by its own gravity; the other dosing mechanism has no tilt angle with the horizontal plane, and the box medicine is pushed into the medicine slot of the dispensing mechanism by the pushing mechanism. At present, the dosing mechanism on the market can only correspond to the same or similar types of box medicines, that is, a box medicine dispensing machine can only accommodate box medicines of the same or similar types of medicine boxes, and the dosing method is single, which is not conducive to the comprehensive management and distribution of box medicines; in addition, the current dosing mechanism is inconvenient to operate and has poor dosing stability, which cannot meet the requirements of the increasingly integrated, intelligent, and efficient automatic dosing of box medicines in hospital pharmacies.

[0003] Chinese patent CN 202358574U, a cache system matched with an automated medicine dispensing device, including a cabinet, a multi-layer medicine receiving cache port arranged on the surface of the cabinet, an automatic control management system in the cabinet, an automatic sensing device and an automatic indicating device embedded in the cabinet, each layer of the medicine receiving cache port is composed of a ramp plate for guiding the medicine to slide down and a layer plate for placing a medicine receiving basket, and each layer of the medicine receiving cache port is embedded with an automatic sensing device for sensing the position of the medicine receiving basket and an automatic indicating device for indicating the status of the medicine receiving basket. The cache system of the present invention matches the automated medicine dispensing device, which not only saves human resources, but also gives full play to the high efficiency performance of the rapid medicine dispensing system. However, the cache system is suitable for a medicine basket dispensing mechanism, which occupies a large area and has high cost, and there are large uncontrollable factors in the process of conveying the medicine basket, which is prone to accidents such as blockage and breakage, and has poor stability. . Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an automatic box dosing device with a cache function. Different numbers of cache mechanisms are configured behind the dosing mechanism according to its working efficiency. Each cache mechanism stores different medicines, which fully solves the problems of the existing dosing mechanism with a single drug variety and slow dosing speed. At the same time, it optimizes the dosing process, makes full use of space and time, improves the comfort of pharmacists' operations, and reduces the labor intensity of pharmacists.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0006] The invention discloses an automatic drug-adding device for box dosage with a buffering function, which is located at the rear of a drug trough of a drug dispensing layer, and comprises a drug-adding mechanism capable of covering any area of ​​the drug trough of the drug dispensing layer through a transmission mechanism, wherein the drug-adding mechanism comprises a drug-adding sliding platform, a drug-pushing mechanism, a drug box clamping mechanism, and a drug box baffle mechanism; the drug-pushing mechanism is arranged on both sides of the drug-adding sliding platform to push the drug box to the drug dispensing layer; the drug box clamping mechanism is arranged on the drug-adding sliding platform to clamp the drug box; the drug box baffle mechanism is arranged at the front end of the drug-adding sliding platform, and a distance corresponding to the width of the drug box is reserved during the drug-adding process to guide the movement direction of the drug box; the device also comprises a buffering mechanism located at the rear of the drug-adding mechanism, and the number of the buffering mechanism arranged in the horizontal direction or / and the vertical direction is at least one; the drug-adding mechanism and the buffering mechanism are both tilted relative to the horizontal direction, and the position of the buffering mechanism is higher than that of the drug-adding mechanism; the drug-adding mechanism can be moved to the front of any buffering mechanism through a transmission mechanism.

[0007] Preferably, the buffer mechanism and the medicine adding mechanism both form an angle of 16° with the horizontal direction.

[0008] Specifically, the cache mechanism includes a frame, a cache sliding platform, a movable guide baffle, a blocking plate and a roller shaft motor, and the roller shaft motor is electrically connected to the movable guide baffle and the blocking plate at the same time; the cache sliding platform is fixed on the frame, and a guide rail is provided on the cache sliding platform, and the movable guide baffle is provided on the guide rail. Under the drive of the roller shaft motor, the movable guide baffle moves back and forth along the guide rail on the cache sliding platform to guide the medicine box and prevent the medicine box from tipping over; the blocking plate is provided at the front end of the cache sliding platform, and moves up and down under the drive of the roller shaft motor to block the medicine box or open the sliding movement of the medicine box.

[0009] Furthermore, a medicine box discharging roller shaft is arranged on the cache sliding platform near the blocking plate, and the medicine box discharging roller shaft is electrically connected to the roller shaft motor, and under the driving force of the roller shaft motor, it is used to assist the medicine box to slide down from the cache sliding platform to the medicine adding sliding platform.

[0010] Furthermore, side guide plates are provided on both sides of the buffer sliding platform, and guide rollers consistent with the sliding direction of the medicine box are provided on the inner side of the side guide plates to reduce the resistance on the side of the medicine box during its sliding down.

[0011] Furthermore, the surfaces of the medicine adding sliding platform and the buffer sliding platform are provided with auxiliary rollers which are consistent with the sliding direction of the medicine box. The auxiliary rollers are fixed on the medicine adding sliding platform and the buffer sliding platform through pins to reduce the friction between the medicine box and the medicine adding sliding platform and the buffer sliding platform, thereby increasing the sliding speed of the medicine box.

[0012] Furthermore, the medicine box clamping mechanism on the medicine adding sliding platform is automatically positioned to the same position according to the position of the movable guide baffle on the buffer sliding platform, and is used to guide the medicine box and prevent the medicine box from tipping over when the medicine box slides down from the buffer sliding platform to the medicine adding sliding platform.

[0013] Preferably, the blocking plate has a thickness of 10 to 15 mm.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) The number of buffer mechanisms in the present invention can be flexibly configured according to the working efficiency of the dosing mechanism. Each buffer mechanism stores different medicines, which fully solves the problem of single drug variety and slow dosing speed of existing dosing mechanisms. At the same time, it optimizes the dosing process, makes full use of space and time, improves the comfort of pharmacists' operations, and reduces the labor intensity of pharmacists.

[0016] (2) The medicine adding mechanism and the buffer mechanism in the present invention are tilted at an angle of 16° to the horizontal direction. Auxiliary rollers that are consistent with the sliding direction of the medicine box are provided on the surfaces of the medicine adding buffer platform and the buffer sliding platform. When the medicine box is placed on the buffer sliding platform, the medicine box can slide down from the buffer sliding platform to the medicine adding sliding platform under the action of its own gravity. In addition, the guide rollers arranged on the inner side of the side guide plate reduce the resistance on the side of the medicine box during its sliding down, thereby improving the smoothness of the sliding down of the medicine box.

[0017] (3) The medicine box clamping mechanism on the medicine adding sliding platform of the present invention is automatically positioned to the same position according to the position of the movable guide baffle on the buffer sliding platform, so as to prevent the medicine box from falling down when the medicine box slides down from the buffer sliding platform to the medicine adding sliding platform.

[0018] (4) In the present invention, a medicine box discharging roller shaft is arranged on the buffer sliding platform near the blocking plate. The medicine box discharging roller shaft rotates under the drive of the roller shaft motor to assist the medicine box to slide from the buffer sliding platform to the medicine adding sliding platform. At the same time, since the thickness of the blocking plate is much smaller than the width of the medicine box, there is no risk of the medicine box tipping over during the descent of the blocking plate.

DETAILED DESCRIPTION

[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] according to Figure 1 and Figure 2 As shown, an automatic drug adding device with a cache function for box dosage is located behind the medicine slot of the medicine dispensing layer, and includes a drug adding mechanism 100 and a cache mechanism 200. The cache mechanism 200 is used to store drugs 300, and the cache mechanism 200 is arranged directly behind the drug adding mechanism 100. There are multiple cache mechanisms 200, which can be arranged in the horizontal direction, in the vertical direction, or even arranged in the horizontal and vertical directions at the same time. The drug adding mechanism 100 can be moved to the front of any cache mechanism 200 through a conveying mechanism. Since the drug adding mechanism 100 and the cache mechanism 200 are placed at 16° with the horizontal direction, and the cache mechanism 200 is higher than the drug adding mechanism 100, when the drug adding mechanism 100 moves to the front of the cache mechanism 200, the medicine box 300 slides down from the cache mechanism 200 to the drug adding mechanism 100 under the action of its own gravity, and then the conveying mechanism moves the drug adding mechanism 100 to the rear of the corresponding medicine slot of the medicine dispensing layer, and the medicine boxes 300 are automatically added to the medicine slot of the medicine dispensing layer in sequence under the action of their own gravity and thrust.

[0029] The medicine adding mechanism 100 includes a medicine adding sliding platform 110, a medicine pushing mechanism 120, a medicine box clamping mechanism 130, and a medicine box baffle mechanism 140; the medicine pushing mechanism 120 is arranged on both sides of the medicine adding sliding platform 110 to push the medicine box 300 to the medicine slot of the medicine dispensing layer; the first guide rail and the second guide rail are respectively installed on the table and the front end of the medicine adding sliding platform 110, and the medicine box clamping mechanism 130 and the medicine box baffle mechanism 140 are respectively arranged on the first guide rail and the second guide rail. Under power drive, the medicine box clamping mechanism 130 moves left and right on the table of the medicine adding sliding platform 110 along the first guide rail to clamp the medicine box 300, and the medicine box baffle mechanism 140 moves left and right along the second guide rail at the front end of the medicine adding sliding platform 110. During the medicine adding process, a distance corresponding to the width of the medicine box 300 is reserved to guide the movement direction of the medicine box 300.

[0030] The cache mechanism 200 includes a frame, a cache sliding platform 210, a movable guide baffle 220, a blocking plate 230 and a medicine box discharging roller shaft 250, and the roller shaft motor 240 is electrically connected to the movable guide baffle 220 and the blocking plate 230 at the same time; the cache sliding platform 210 is fixed on the frame, and side guide plates 260 are installed on both sides of the cache sliding platform 210. A third guide rail is arranged on the table top, and the movable guide baffle 220 is arranged on the third guide rail. Under the drive of the roller shaft motor 240, the movable guide baffle 220 moves along the third guide rail on the table top of the cache sliding platform 210 to guide the medicine box 300 and prevent the medicine box 300 from tipping over; the blocking plate 230 is arranged at the front end of the cache sliding platform 210, and can move up and down under the drive of the roller shaft motor 240 to block the medicine box 300 or open the medicine box 300 from sliding down.

[0031] A medicine box discharging roller shaft 250 is arranged near the blocking plate 230 on the buffer sliding platform 210, and the medicine box discharging roller shaft 250 is electrically connected to the roller shaft motor 240. Driven by the roller shaft motor 240, the auxiliary medicine box 300 slides down from the buffer sliding platform 210 to the medicine adding sliding platform 110. Since the thickness of the blocking plate 230 is only 10 mm to 15 mm, which is much smaller than the width of the medicine box 300, the medicine box 300 will not have the risk of tipping over during the descent of the blocking plate 230. In addition, the surfaces of the buffer sliding platform 210 and the medicine adding sliding platform 110 are provided with Auxiliary rollers 400 are provided, and the auxiliary rollers 400 are fixed on the table surfaces of the medicine adding sliding platform 110 and the buffer sliding platform 210 through pins; guide rollers 270 are provided on the inner sides of the side guide plates 260 on both sides of the buffer sliding platform 210, and the sliding directions of the auxiliary rollers 400 and the guide rollers 270 are consistent with those of the medicine box 300, so as to reduce the resistance on the bottom and sides of the medicine box 300 when it slides down from the buffer sliding platform 210 to the medicine adding sliding platform 110 and from the medicine adding sliding platform 110 to the medicine slot of the medicine dispensing layer, thereby improving the smoothness of the medicine box 300 when it slides down.

[0032] The specific working process of the present invention is as follows:

[0033] The dosing mechanism 100 and the cache mechanism 200 are both controlled by the main control machine. After confirming the type of medicine to be added on the main control machine, the movable guide baffle 220 is automatically moved to the opposite direction of the side where the medicine needs to be added under the drive of the roller shaft motor 240, and the blocking plate 230 is in a raised state under the drive of the roller shaft motor 240. Then the operator adds the required medicine to the cache sliding platform 210. The added medicines are required to scan the information obtained by the medicine box 300; since the cache sliding platform 210 is tilted, the medicine box 300 will slide down to the position of the blocking plate 230. At this time, the movable guide baffle 220 is automatically moved toward the medicine box under the drive of the roller shaft motor 240 and after clamping the medicine box 300, the movable guide baffle 220 moves in the opposite direction by 5mm, so that the medicine box 300 does not completely contact the movable guide baffle 220, so as to reduce the friction when the medicine box 300 slides down. Since the width of the medicine box 300 is generally much larger than 5mm, it can also prevent the medicine box 300 from tipping over.

[0034] The medicine adding mechanism 100 is moved to the front of the buffer mechanism 200 through the conveying mechanism. When it reaches the correct position, the medicine box clamping mechanism 130 on the medicine adding sliding platform 110 will automatically locate to the same position according to the position of the movable guide baffle 220 on the buffer sliding platform 210. When the medicine box 300 slides down from the buffer sliding platform 210 to the medicine adding sliding platform 110, it prevents the medicine box 300 from tipping over; at the same time, the medicine box baffle mechanism 140 moves to the side corresponding to the medicine box 300; after the above actions are completed, driven by the roller shaft motor 240, the medicine box outlet roller shaft 250 on the buffer sliding platform 210 rotates, and the baffle plate 230 moves downward. When the height of the baffle plate 230 is lower than the table surface of the buffer sliding platform 210, the medicine box 300 slides down to the medicine box baffle mechanism 140 of the medicine adding sliding platform 110 under the assistance of its own gravity and the auxiliary roller 400 on the table surface of the buffer sliding platform 210 and the guide roller 270 on the side guide plate 260. Figure 3 shown.

[0035] like Figure 4 As shown, after the medicine box 300 slides down to the medicine adding sliding platform 110, the medicine box clamping mechanism 130 continues to clamp toward the medicine box 300, and the medicine adding mechanism 100 as a whole moves to the rear of the designated medicine dispensing layer medicine slot under the action of the transmission mechanism, and the medicine box baffle mechanism 140 reserves an opening according to the width of the medicine box, and then the medicine pushing mechanism 120 on the side of the medicine adding sliding platform 110 is activated to push the medicine box 300 into the medicine dispensing layer medicine slot. The medicine pushing mechanism 120 includes a driving motor, a driving synchronous pulley, a driven synchronous pulley, and a synchronous belt 121 sleeved on the driving synchronous pulley and the driven synchronous pulley, and a push plate 122 is symmetrically arranged at the front and rear ends of the synchronous belt 121 for pushing the medicine box into the medicine dispensing layer medicine slot. When the medicine pushing mechanism 120 is in action, the pushing plate 122 on its synchronous belt 121 pushes the leftmost or rightmost medicine box 300 into the medicine slot of the medicine dispensing layer, and then the medicine box clamping mechanism 130 pushes the remaining medicine boxes 300 to the leftmost or rightmost side, and the pushing plate 122 continues to move once to complete the dosing of one medicine box 300, and the above actions are completed in sequence until all the medicine boxes 300 on the dosing sliding platform 110 are added.

[0036] like Figure 5 and 6As shown, two buffer mechanisms 200 are provided in the longitudinal direction, and the medicine adding mechanism 100 is moved to the front of the first buffer mechanism 100 through the transmission mechanism, and the medicine box 300 on the buffer mechanism 200 slides down to the medicine adding mechanism 100, and then the transmission mechanism transmits the medicine adding mechanism 100 to the rear of the medicine slot of the designated medicine dispensing layer, and the medicine boxes 120 on the medicine adding mechanism 100 are automatically added to the medicine slot of the medicine dispensing layer in turn; then, the medicine adding mechanism 100 moves to the front of another buffer mechanism 200, and continues to automatically add the next type of medicine; in this process, the blocking plate 230 on the buffer mechanism 200 in an empty state is raised under the drive of the roller shaft motor 240, and at this time, the operator can replenish medicines to the buffer mechanism 200.

[0037] The present invention can configure different numbers of cache mechanisms 200 according to the working efficiency of the dosing mechanism 100. Each cache mechanism 200 stores different medicines, which fully solves the problem of the existing dosing mechanism 100 having a single drug variety and a slow dosing speed. At the same time, it optimizes the dosing process, fully utilizes space and time, improves the comfort of pharmacists' operations, and reduces the labor intensity of pharmacists.

[0038] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any changes that adopt the design principles of the present invention and are made through non-creative labor on this basis should fall within the protection scope of the present invention.
