Description

Technical Field

[0001] The present invention belongs to the technical field of medicine dispensing machines, and in particular relates to a medicine dispensing machine and a method for preventing confusion in medicine dispensing from packaging bags. Background Art

[0002] At present, large hospitals use packaging bags to package Chinese medicine granules, which have the advantages of being easy to carry, convenient to use, and low in packaging cost. Since the appearance of each aluminum-plastic packaging bag is the same, it may cause confusion among the bags after the medicine is dispensed, and the mixed packaging bags are difficult to distinguish. Summary of the invention

[0003] In order to solve the above technical problems, the present invention discloses a medicine dispensing machine, which can avoid confusion of packaging bags after dispensing medicines by printing a scanning code on a roll film and scanning the code using a scanning mechanism in the medicine dispensing machine. The present invention also discloses a method for preventing confusion of packaging bags when dispensing medicines.

[0004] The specific technical solutions of the present invention are as follows:

[0005] A medicine dispensing machine, the medicine dispensing machine receives a roll film output from a film roll rack, the roll film being uniformly printed with a scanning code in a first length;

[0006] The medicine dispensing machine is provided with a forming mechanism, the film roll passes through the forming mechanism, and a code scanning mechanism is provided on one side of the forming mechanism for scanning a scanning code printed on the film roll.

[0007] The scanning mechanism on the medicine dispensing machine can scan the scanning code on the roll film. Since the scanning code is unique, the subsequently formed packaging bag is unique, which can effectively distinguish mixed medicines and effectively avoid the wrong dispensing of medicines. The forming mechanism can realize the shaping of the packaging bag, so that the packaging bag is in an open state. At this time, when the scanning mechanism is used to scan the code, the scanning failure caused by light and shadow can be well avoided.

[0008] Preferably, a light-through hole is provided on one side of the molding mechanism, and the code scanning mechanism scans the scanning code on the roll film at the light-through hole.

[0009] The structure is simple and practical, and does not affect the forming effect of the roll film.

[0010] Preferably, a guiding mechanism is provided between the forming mechanism and the film rolling frame;

[0011] The guiding mechanism comprises a swingable guiding member which is arranged in the medicine dispensing machine.

[0012] The guide member can swing relative to the medicine dispensing machine so that it can adaptively adjust the tension of the film roll, thereby ensuring the accuracy of code scanning and effectively avoiding code scanning failure.

[0013] Preferably, one end of the guide member is hinged to the medicine dispensing machine, and the other end is provided with a guide roller.

[0014] The guide roller is in contact with the roll film, so that the roll film can smoothly enter the forming mechanism. Since the guide member and the dispenser are in a hinged relationship, the guide member may swing with the dispenser during the movement of the roll film. Therefore, the tension of the roll film can be adjusted by swinging, so that the roll film is always stretched during the movement of the roll film, which is conducive to scanning the code.

[0015] Preferably, the guide member adjusts the tension of the film roll by gravity; or

[0016] An elastic member is arranged between the guide member and the medicine dispensing machine, and the tension of the roll film is adjusted by the reset deformation force of the elastic member.

[0017] The above structure is simple and easy to implement, and can well meet the tension adjustment requirements.

[0018] Preferably, the forming mechanism comprises:

[0019] A mandrel fixedly arranged in the medicine dispensing machine or in a free state, the mandrel is located inside the forming mechanism, a movement gap is provided between the outer wall of the mandrel and the inner wall of the forming mechanism, the mandrel has a bag stretching portion, so that the roll film passes through the movement gap in an open state, and the mandrel is provided with at least one holding portion along its axial direction for keeping the roll film open;

[0020] When the mandrel is in a free state, the forming mechanism further comprises:

[0021] The limiting assembly is used to limit the vertical movement of the core rod.

[0022] The core rod can guide the movement of the roll film and keep the roll film in an open state at the forming mechanism; when the core rod is set in a free state, the movement is limited by the limiting assembly and is not fixed on the bag making assembly. Therefore, compared with the prior art, it is easy to assemble into the bag making assembly and easy to be removed for maintenance. That is to say, the staff can remove the core rod regularly or irregularly for cleaning and disinfection, so as to maintain the cleanliness of the material after bagging.

[0023] Preferably, the limiting component comprises:

[0024] A supporting roller, the supporting roller being located at one end of the mandrel for bagging to limit the downward displacement of the mandrel; and

[0025] The limiting rollers are arranged on two opposite sides of the mandrel and are used to limit the lateral displacement of the mandrel.

[0026] In the prior art, the mandrel is fixed to the medicine dispensing machine of the bag-making assembly by a fixing part, which means that the fixing part needs to be operated during the process of disassembling and assembling the mandrel. Since the bag-making assembly requires that each structural component be as compact as possible, the operation of the fixing part is relatively complicated. In the present application, the supporting roller can support the mandrel and limit the lateral displacement of the mandrel by a limiting roller, so that the mandrel can be stably assembled in the bag-making assembly without passing through a fixing part. It can be seen that this structure can also simplify the process of removing the mandrel, thereby greatly facilitating the disassembly and assembly of the mandrel.

[0027] A method for preventing confusion in dispensing medicines from packaging bags comprises the following steps:

[0028] Printing a scanning code uniformly with a first length on the continuously formed roll film;

[0029] Place the film roll on the film roll rack, output the film roll to the dispenser through the film pulling mechanism, and pass the film roll through the code scanning mechanism;

[0030] The scanning code on the roll film is scanned in sequence by the scanning mechanism to obtain a plurality of first information in sequence;

[0031] The scanned roll film is sealed and cut at a first length on a sealing and cutting mechanism to form packaging bags, each of which has a unique scanning code;

[0032] According to the first information, each packaging bag is matched with a bag insertion hole on the medicine dispensing turntable;

[0033] Transfer the bag into its matching pocket.

[0034] Preferably, the medicine dispensing machine is provided with a sensing device to determine whether a packaging bag is stored in the bag insertion hole;

[0035] According to the first information, the packaging bag is matched to the bag insertion hole where no packaging bag is stored.

[0036] Preferably, it also includes:

[0037] The drug information is obtained according to the prescription information, and the drug information is matched to the pocket hole to correspond to the first information matched with the pocket hole.

[0038] Compared with the prior art, the present invention enables each packaging bag formed by the medicine dispensing machine to have an independent scanning code, so the information of each packaging bag is certain. When dispensing medicine, the type of medicine contained in the packaging bag can be determined based on the information, thereby avoiding confusion. Even after confusion, the above information can be obtained through an independent scanning gun, so that the confused packaging bags can be distinguished. In addition, the present invention has a simple structure, is practical and convenient, and can well meet the scanning requirements of the scanning code. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.

[0045] like Figure 1-2 , Figure 4 As shown, a medicine dispensing machine 1 receives a roll film 3 output from a film roll rack 2, and the roll film 3 is printed with a scanning code 4 evenly in a first length; a forming mechanism 5 is provided in the medicine dispensing machine 1, and the roll film 3 passes through the forming mechanism 5, and a scanning mechanism 6 is provided on one side of the forming mechanism 5 for scanning the scanning code 4 printed on the roll film 3.

[0046] The medicine dispensing machine 1 has a sealing and cutting mechanism, which can realize the lower horizontal sealing and cutting of the roll film 3, so that the continuous roll film 3 is formed into an independent packaging bag, and the packaging bag has an upper opening, so as to meet the demand for dispensing medicine. Since the scanning code 4 is printed at intervals of the first length, during the sealing and cutting process, the sealing and cutting are also realized at the first length, thereby realizing that every other packaging bag has an independent and unique scanning code 4, so that each packaging bag has uniqueness, thereby being able to well avoid confusion in dispensing medicine. The scanning code 4 is a two-dimensional code or a bar code.

[0047] In the process of the roll film 3 moving along the forming mechanism 5, since there are multiple scanning codes 4, the scanning mechanism 6 scans the multiple scanning codes 4 in turn and records them in the control system. After bagging, the bag insertion holes of the turntable are matched. Therefore, when dispensing medicines, the prescribed medicines can be dispensed into the packaging bags with known information. After the dispensing is completed and the horizontal sealing is performed, the packaging bags can be picked up according to the information, thereby avoiding confusion in the dispensing of medicines.

[0048] It should be noted that, in the present embodiment, the roll film 3 may be a roll film 3 that has been vertically sealed, or may be a roll film 3 that has not been vertically sealed.

[0049] In this embodiment, a light hole 7 is provided on one side of the molding mechanism 5, and the code scanning mechanism 6 scans the scanning code 4 on the roll film 3 at the light hole 7. The code scanning mechanism 6 can illuminate the roll film 3 moving along the molding mechanism 5 through the light hole 7, thereby preventing the roll film 3 from stopping to be scanned and affecting the process efficiency.

[0050] In this embodiment, a guide mechanism is provided between the forming mechanism 5 and the film roll frame 2; the guide mechanism includes a swingable guide member 8 provided in the medicine dispensing machine 1. Further, one end of the guide member 8 is hinged to the medicine dispensing machine 1, and the other end is provided with a guide roller 9. In this embodiment, the guide mechanism also includes a plurality of steering rollers 10, and the film roll frame 2 outputs the film roll 3 into the medicine dispensing machine 1 through the plurality of steering rollers 10, and finally outputs it to the forming mechanism 5 through the guide member 8. Since the guide member 8 can swing freely relative to the medicine dispensing machine 1, the guide member 8 is adaptively adjusted according to the movement of the film roll 3 to meet the tensioning requirements of the film roll 3. In some technical solutions of this embodiment, the guide member 8 adjusts the tension of the film roll 3 by gravity. In some other embodiments of this embodiment, an elastic member is provided between the guide member 8 and the medicine dispensing machine 1, and the tension of the film roll 3 is adjusted by the reset deformation force of the elastic member, and the elastic member can be a columnar spring or a torsion spring. Through the above-mentioned structural setting, the number of times the user adjusts the guide 8 can be reduced. That is to say, in the prior art, since the guide 8 is subjected to force during the movement of the film roll, it may deviate relative to the original position after a period of use, which leads to insufficient tension of the film roll, and thus the guide 8 needs to be adjusted once in a while. After adopting the adaptive structure, the above-mentioned operation can be avoided well, thereby reducing downtime and improving the efficiency of dispensing medicines.

[0051] In some technical solutions of this embodiment, the molding mechanism 5 includes a core rod 11 fixedly arranged in the medicine dispensing machine 1. In some technical solutions, the core rod 11 is in a free state. The core rod 11 is located inside the molding mechanism 5. In this embodiment, there is a movement gap between the outer wall of the core rod 11 and the inner wall of the molding mechanism 5. The core rod 11 has a bag stretching portion 12 so that the roll film 3 passes through the movement gap in an open state. The core rod 11 is provided with at least one retaining portion 13 along its axial direction for keeping the roll film 3 open; when the core rod 11 is in a free state, the molding mechanism 5 also includes a limiting assembly for limiting the core rod 11 to move vertically. The core rod 11 in a free state is described in detail below. The retaining portion 13 in this embodiment is configured as a roller arranged on the core rod 11 and rotatable around its own axis.

[0052] In this embodiment, the molding mechanism 5 is fixedly arranged on the medicine dispensing machine 1 to form a channel for the film roll 3 to pass through. The film roll frame 2 outputs the film roll 3 to the above-mentioned channel through a number of turning rollers 10 and guide rollers 9. A mandrel 11 is arranged in the channel. The mandrel 11 is not fixedly connected to the medicine dispensing machine 1, but is limited by a limiting component in a free state by its own gravity to form a movement gap between the outer side of the mandrel 11 and the inner side of the molding mechanism 5, so that the film roll 3 passes through the movement gap and remains in an open state under the action of the bag stretching part 12. It is known that a film pulling mechanism 14 is arranged on the medicine dispensing machine 1, and the film roll 3 can be pulled to move by the film pulling mechanism 14 acting on the vertical sealing edge of the film roll 3. In this embodiment, the bottom of the mandrel 11 is the end of the mandrel 11 for entering the bag, and the top of the mandrel 11 is the end of the mandrel 11 for exiting the bag. Based on this, there must be an opening at the upper end of the mandrel 11 for the roll film 3 to move out of the movement gap. Therefore, when it is necessary to remove the mandrel 11 for cleaning and disinfection, the mandrel 11 can be directly taken out from the above opening. Similarly, when installing the mandrel 11, the mandrel 11 can be placed from the opening. Even if the above-mentioned operation process is difficult to take and put, it is only necessary to disassemble and assemble the limit assembly. Therefore, compared with the prior art, under ideal conditions, the mandrel 11 can be directly taken and put in the channel for the roll film 3 to pass through. Even if the conditions are difficult, it is only necessary to disassemble and assemble the limit assembly. No matter what method is used, the mandrel 11 fixedly set on the medicine dispensing machine 1 can be avoided. This greatly provides convenience for the staff, so the mandrel 11 can be better disinfected.

[0053] like Figure 3As shown, in this embodiment, the limiting assembly includes a supporting roller 15 and a limiting roller 16; the supporting roller 15 is located at one end of the mandrel 11 for bagging to limit the downward displacement of the mandrel 11; the limiting roller 16 is arranged on the opposite sides of the mandrel 11 to limit the lateral displacement of the mandrel 11. When the mandrel 11 is installed in the medicine dispensing machine 1, the supporting roller 15 is located at the lower end of the mandrel 11, and the limiting roller 16 is located at the side of the mandrel 11. The supporting roller 15 provides support for the mandrel 11, so that the mandrel 11 maintains a relative position with the medicine dispensing machine 1 in a certain area under its own weight. During the conveying process of the film roll 3, due to the friction between the film roll 3 and the mandrel 11, the mandrel 11 may have a relative displacement with the medicine dispensing machine 1 in the above-mentioned area, but under the condition of the mandrel 11's own weight, it only moves in a small range, so the above-mentioned area is the small range of movement of the mandrel 11. At the same time, the limiting roller 16 limits the lateral displacement of the core rod 11 to prevent the core rod 11 from excessively moving in the lateral direction and causing obvious tilting, thereby avoiding affecting the conveying of the roll film 3. In this embodiment, the roll film 3 is a roll film 3 that has been folded and sealed vertically. Therefore, the finished roll film 3 formed by the final bag making only needs one opening. Since this embodiment adopts a bag making process from bottom to top, it is necessary to keep the roll film 3 in the stretched open state in the forming space during the bag making process. Therefore, the stretching bag part 12 can make the roll film 3 open and always keep the open state during the movement. When the roll film 3 moves in the movement gap in this state, it can also reduce the contact area between the core rod 11. That is, the stretching bag part 12 and the roll film 3 are in short contact. The short contact includes one or more of small area contact, short straight line segment contact, short arc segment contact and point contact. Therefore, the stretching bag part 12 can also improve the driving efficiency of the film drawing unit.

[0054] Based on the above embodiment, this embodiment further discloses a method for preventing confusion in dispensing medicines from packaging bags, comprising the following steps:

[0055] S100, printing a scanning code 4 uniformly with a first length on a continuously formed roll film 3;

[0056] S200, roll the film 3 onto the film roll rack 2, output the film 3 to the medicine dispenser 1 through the film pulling mechanism 14, and pass the film 3 through the code scanning mechanism 6;

[0057] S300, using the code scanning mechanism 6 to sequentially scan the scanning codes 4 on the roll film 3 to sequentially obtain a plurality of first information;

[0058] S400, the scanned roll film 3 is sealed and cut at a first length on a sealing and cutting mechanism to form packaging bags, each packaging bag having a unique scanning code 4;

[0059] S500, according to the first information, each packaging bag is matched with a bag insertion hole on the medicine dispensing turntable;

[0060] S600, transfer the packaging bag to its matching bag insertion hole.

[0061] In this embodiment, a plurality of unique scanning codes 4 are printed in advance in a certain length in the customized pattern of the roll film 3 at intervals to ensure that in the subsequent bag making process, the packaging bags customized according to the regulations all have unique scanning codes 4. When each packaging bag passes through the mandrel 11, it can be scanned and the information can be recorded by the scanning mechanism 6 installed on the side of the forming mechanism 5. Since the scanning code 4 is unique, the packaging bag scanned is also unique.

[0062] S700, obtaining drug information according to prescription information, and matching the drug information to the pocket hole to correspond to the first information matched with the pocket hole.

[0063] When the packaging bag is scanned, its information is recorded in the control system of the medicine dispensing machine 1. According to the first information of the corresponding packaging bag, the packaging bag is matched to the vacant pocket hole through the control system, so the packaging bag has a preset position on the turntable, so that the corresponding medicine can be dispensed. Furthermore, the medicine dispensing machine 1 is provided with a sensing device to determine whether there is a packaging bag in the pocket hole; according to the first information, the packaging bag is matched to the pocket hole where no packaging bag is stored. Therefore, after dispensing the medicine, the user can take the bags in order according to the first information, which can further avoid confusion of the packaging bags. Even if the packaging bags are confused during the storage process, they can be distinguished according to the first information of the scanned code to avoid wrong delivery.

[0064] Therefore, in the process of using this embodiment, the film roll 3 is installed on the film roll frame 2. After the film roll passes through the steering rollers 10 and the guide 8, the core rod 11 and the forming mechanism 5 keep the film roll opening in a certain shape. The vertical sealing edge of the film roll moves upward under the action of the film pulling mechanism 14. A light hole 7 is provided on one side of the forming mechanism 5. When the film roll passes through the light hole 7, the scanning code 4 is exposed, and is scanned and recorded by the scanning mechanism 6. At the same time, the first information will be matched to the pocket insertion hole on the turntable by the control system accordingly; when the prescription information is input into the medicine dispensing machine 1, the control system automatically matches the packaging bag of the empty bag, thereby rotating the turntable to the medicine dispensing mechanism to dispense the medicine. This can well avoid confusion of the packaging bags, thereby ensuring that the prescription is dispensed correctly.

[0065] The above are only preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be regarded as limiting the present invention, and the protection scope of the present invention should be based on the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
