Description

Technical Field

[0001] The utility model mainly relates to the technical field of medicine packaging equipment, in particular to a medicine film discharging buffer device of a medicine packaging machine. Background Art

[0002] Automatic packaging machines have been used for more than 30 years. With the in-depth development of information technology in my country's medical industry, hospital pharmacy automation has gradually become popular, making pharmacy work more efficient and standardized. The packaging machine can automatically complete the entire process of dispensing medicines, from selecting the correct medicine to storing, counting, filling and packaging medicines.

[0003] The medium for packaging medicines is usually called medicine film. The medicine film is rolled up inside the packaging machine and installed on the unwinding device. It is first printed with information by the printing device, then filled with medicine by the forming and dropping device, and then sealed into continuous medicine packages by the heat sealing device, and finally sent out by the conveying device. The medicine filled in the medicine package must strictly correspond to the printed information.

[0004] The material of the medicine film used in the packaging machine is mostly a composite of cellophane (cellulose acetate) or PE (polyethylene). The product itself is soft and thin, and tension or heat will cause it to produce slight deformation.

[0005] In the prior art, the medicine film of the packaging machine product is packaged after being printed by a printer, and the power for unwinding the medicine film comes from the traction force at the packaging position, and the printing device between the packaging device and the medicine film unwinding device will affect the transmission of the traction force. On the other hand, the packaging device is too far away from the installation position of the medicine film and the medicine film is a circular coil. The pulling force required to unwind it from the outer roll to the inner roll varies with the change of the diameter. In summary, the existing structure will cause uneven tensioning force of the medicine film, deviation in the position of the medicine film entering the printer, and offset of the printed font on the position of the medicine film. The packaging effect will also be affected after the medicine film is offset, and the printed medicine bag will not look good. In severe cases, it may lead to medical accidents.

[0025] Embodiment: A medicine film dispensing and caching device for a medicine packaging machine

[0026] like Figure 1-4As shown, a medicine film outgoing film buffer device of a medicine packaging machine, the specific structure of which includes:

[0027] A frame 1 is provided, a medicine film bag discharging and winding mechanism 2 is rotatably mounted on the lower part of one front side of the frame 1, a medicine film bag discharging and winding mechanism 2 is provided with a medicine film roll 3, a paper tape roller mechanism 4 is provided in the middle part of one front side of the frame 1, a plurality of medicine film guiding mechanisms 5 arranged in an "S" shape are rotatably mounted on the upper part of the front of the frame 1, a medicine film guide column 6 is fixedly mounted on the upper part of the other side of the frame 1, and a tensioning component is provided at the rear of one of the medicine film guiding mechanisms 5.

[0028] The medicine film guiding mechanism 5 includes a medicine film guiding roller shaft 501, one end of which is fixedly connected to the frame 1, and a medicine film guiding roller 502 is rotatably mounted on the outside of the medicine film guiding roller shaft 501 through a bearing, and the front and rear ends of the medicine film guiding roller 502 are both inclined inward along the edge. The medicine film guiding roller shaft 501 supports the medicine film guiding roller 502, and the medicine film guiding roller 502 is in direct contact with the medicine film to guide and transport the medicine film. The medicine film guiding roller 502 can reduce the friction during the transportation of the medicine film and improve the smoothness of the medicine film transportation. The two ends of the medicine film guiding roller 502 are inclined surfaces, which can automatically guide the medicine film within a specified range.

[0029] The tensioning assembly includes a linear guide rail 8, a first through slot 7 is provided at the upper front part of the frame 1, a linear guide rail 8 is fixedly installed in the first through slot 7, a slider 9 is slidably installed on the linear guide rail 8, one of the medicine film guide roller shafts 501 is fixedly installed in front of the slider 9, and the front of the slider 9 is fixedly connected to the rear end of the corresponding medicine film guide roller shaft 501. After the medicine film roll 3 releases the medicine film, the medicine film passes through the paper tape roller mechanism 4, and is sequentially wound on the medicine film guide mechanism 5 from left to right, and finally winds up the medicine film guide column 6 and then turns along the 45° direction (angle with the horizontal direction) to enter the printer. The medicine film is wound between the medicine film guide roller shaft 501 connected to the slider 9 and the two adjacent medicine film guide roller shafts 501 on both sides thereof at a V-shaped angle. This arrangement can ensure that the tension of the medicine film on both sides of the tensioning assembly is basically consistent, prevent the medicine film from being subjected to uneven force, and improve the stability of the device.

[0030] The unwinding sensors 10 are symmetrically installed at the upper and lower parts of the rear of the frame 1. The unwinding sensors 10 are electrically connected to the power supply. The medicine film buffer sensor plate 11 matching the unwinding sensors 10 is fixedly installed at the rear of the slider 9. The medicine film buffer sensor plate 11 is located between the two unwinding sensors 10. The medicine film passes around the medicine film guide roller shaft 501 located on the slider 9 at the bottom, and the medicine film is pressed under the action of the gravity of the slider 9 and the medicine film guide roller shaft 501. When the printer prints, the medicine film moves forward. At this time, under the action of the force, the medicine film slides upward along the linear slide rail 8 with the corresponding medicine film guide roller shaft 501 and the slider 9, thereby realizing the dynamic adjustment of the tension of the medicine film.

[0031] The medicine film bag discharging and winding mechanism 2 includes a paper tape rotating shaft 12, the lower part of the frame 1 is rotatably mounted with the paper tape rotating shaft 12, the front end of the paper tape rotating shaft 12 is threadedly mounted with a detachable medicine roll anti-drop button 13, and the rear part of the outer periphery of the paper tape rotating shaft 12 is fixedly mounted with a paper tape support plate 14 that matches the paper tape rotating shaft 12. When this structural design is used, after the medicine film roll 3 is set on the paper tape rotating shaft 12, it is locked by the medicine roll anti-drop button 13, and the paper tape support plate 14 can support the medicine film roll 3, which can improve the stability of the medicine film roll 3, and has a simple structure and is easy to use.

[0032] A second through slot 15 is provided on one side in front of the frame 1, a film feeding motor fixing plate 16 is fixedly installed on the back of the frame 1, the film feeding motor fixing plate 16 is located behind the second through slot 15, a film feeding motor 17 is fixedly installed in front of the film feeding motor fixing plate 16, the output shaft of the film feeding motor 17 penetrates the film feeding motor fixing plate 16 and extends to the back of the frame 1, the paper tape transfer shaft 12 penetrates the frame 1 longitudinally and is connected to its bearing, the output end of the film feeding motor 17 and the rear end of the paper tape transfer shaft 12 are respectively fixedly installed with synchronous pulleys 18, and the two synchronous pulleys 18 are connected through a synchronous belt 19 for transmission. When the printer is printing, the medicine film moves forward. At this time, under the action of force, the medicine film slides upward along the linear slide rail 8 with the corresponding medicine film guide roller shaft 501 and the slider 9. When the unwinding sensor 10 located above senses that the medicine film buffer sensor plate 11 has reached the upper position, the film feeding motor 17 starts to release the medicine film. At this time, the medicine film is loose. Under the action of the gravity of the slider 9 and the medicine film guide roller shaft 501, the slider 9 drives the medicine film guide roller shaft 501 connected thereto to move downward and press the medicine film. When the unwinding sensor 10 located below senses that the medicine film buffer sensor plate 11 has reached the upper position, the film feeding motor 17 starts to operate and starts to release the medicine film. When the medicine film buffer sensor plate 11 reaches the lower position, the motor 17 is turned off and stops releasing the medicine film. During the normal medicine packaging process, as the printer keeps printing, the slider 9 drives the medicine film buffer sensor plate 11 to move between the two unwinding sensors 10 to tighten the medicine film. At the same time, the film feeding motor 17 performs intermittent motion to release the medicine film, thereby realizing dynamic control of the film feeding motor 17 to ensure that the force of the medicine film entering the printer is controllable. At the same time, changing the medicine film roll 3 to an electric film releasing method can avoid the problem of uncontrollable film tensioning force due to differences in the winding force of the medicine roll.

[0033] The paper tape roller mechanism 4 includes a paper tape support roller shaft 401, which is fixedly mounted in the middle of one side of the front of the frame 1, and a paper tape support roller 402 is rotatably mounted on the outer periphery of the paper tape support roller shaft 401 through a bearing, and a front paper separation needle 20 is rotatably mounted on the front end of the paper tape support roller shaft 401 through a bracket. The paper tape support roller 402 can support the medicine film and improve the smoothness of the medicine film conveying process, and the front paper separation needle 20 can play a role in pre-separating the medicine film by free radial rotation, reducing the resistance of the medicine falling and separating the medicine film.

[0034] The two sides of the bottom of the front of the frame 1 are respectively fixedly mounted with fixed support plates 21, and the top surface of the fixed support plates 21 is provided with mounting holes. The fixed support plates 21 can facilitate the user to fix the frame 1 on the work platform by bolts, so as to facilitate the installation of the frame 1.

[0035] A paper tape sensor bracket 22 is fixedly mounted in front of the frame 1. The paper tape sensor bracket 22 is located obliquely above the medicine film bag winding mechanism 2. A paper tape sensor is mounted on the paper tape sensor bracket 22. After the medicine film is output through the medicine film roll 3, it first passes through the paper tape sensor bracket 22. The paper tape sensor is responsible for detecting whether there is a paper tape in front of it. When the medicine film roll 3 is exhausted, the medicine film is away from the paper tape sensor, the paper bag sensor issues an alarm, the equipment stops running, and the system prompts that the medicine film is exhausted and the medicine roll needs to be replaced. When the medicine roll is replaced, the medicine film is passed through the paper tape sensor bracket 22 again so that the paper tape sensor recognizes the medicine film, the alarm information is eliminated, and the equipment starts to operate normally.

[0036] The present solution also includes a controller, the position of which is set by the staff according to actual conditions during operation. The controller is used to control the electrical devices used in the present solution, including but not limited to sensors, motors, telescopic rods, water pumps, solenoid valves, heating wires, heat pumps, display screens, computer input devices, switch buttons, communication equipment, lights, speakers and microphones; the controller is an Intel processor, an AMD processor, a PLC controller, an ARM processor or a single-chip microcomputer, and the supporting motherboard, memory stick, storage medium and power supply are also included therewith, and the power supply is AC or a lithium battery; when a display screen is provided, a display card is also provided; for the operating principle of the controller, please refer to "Principles of Automatic Control", "Principles of Microcontrollers and Application Simulation Cases" and "Principles and Applications of Sensors" published by Tsinghua University Press, and other books in the field can be used for reference; other automatic controls and electrical devices not mentioned are all knowledge well known to those skilled in the art and will not be repeated here.

[0037] Working principle:

[0038] When the device is in use, after the medicine film is released from the medicine film roll 3, it first passes through the paper tape roller mechanism 4, and then is wound on the medicine film guide mechanism 5 from left to right, and finally is wound upwards on the medicine film guide column 6, and then turns along a 45° direction to reach the printer entrance.
