Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of food and medicine packaging equipment, in particular to a blister machine. Background Art
[0002] Glass bottles can be bumped and knocked during transportation through upstream and downstream equipment. Once loaded into the bottle tray, there's a risk of the bottles breaking or cracking, especially with ampoule tips. Leaked liquid medicine can contaminate the entire tray and reduce the number of finished products within. Currently, blister packaging machines lack leak detection after glass bottles are placed in the tray. Products with broken bottles in the tray can be directly boxed, posing quality risks to the products in the box. Blister packaging machines typically use visual inspection, which makes it difficult to detect potential cracks in the bottle walls, and even more so after the trays are coated. Utility Model Content
[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a blister machine with a simple structure, good reliability and the ability to detect whether there are broken bottles or cracks on the bottle walls.
[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:
[0005] A blister machine includes a conveying mechanism, which is equipped with a bottle support forming mechanism, a bottle body support mechanism and a laminating mechanism in sequence along the conveying direction. A discharge leakage detection mechanism is also provided between the bottle body support mechanism and the laminating mechanism. The discharge leakage detection mechanism includes an emitting electrode and a receiving electrode arranged at intervals in the upper and lower directions, and a leakage detection channel is formed between the emitting electrode and the receiving electrode.
[0006] As a further improvement of the above technical solution: the discharge leakage detection mechanism further includes a power supply, which is respectively connected to the transmitting electrode and the receiving electrode, and the transmitting electrode and / or the receiving electrode is connected to a lifting drive member.
[0007] As a further improvement of the above technical solution: the transmitting electrode is located above the receiving electrode, and the lifting drive member is connected to the transmitting electrode.
[0008] As a further improvement of the above technical solution: a sampling resistor is connected between the power supply and the emitting electrode.
[0009] As a further improvement of the above technical solution: the emitting electrode includes an emitting electrode sheet and a plurality of needle tips provided on the emitting electrode sheet.
[0010] As a further improvement of the above technical solution: the needle tip is provided on the lower surface of the transmitting electrode sheet, the receiving electrode comprises a receiving electrode sheet, and the receiving electrode sheet is located below the needle tip.
[0011] Compared with the prior art, the advantages of the present utility model are as follows: For the blister machine disclosed by the present utility model, the PVC film material is conveyed through a conveying mechanism. When passing through the bottle tray forming mechanism, a bottle tray is formed. When passing through the bottle body loading mechanism, the bottle body is loaded into the bottle tray. Before the bottle tray with the bottle body is covered with a film by the film covering mechanism, discharge leak detection is first carried out between the emitting electrode and the receiving electrode, so as to judge whether there is a broken bottle or whether there are cracks on the bottle wall, avoiding the adverse impact of film covering on detection. At the same time, compared with the commonly used visual inspection, the discharge leak detection has better accuracy and reliability.
[0012] Other features and advantages of the present utility model will be described in detail in the subsequent specific implementation part. Brief Description of the Drawings

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0023] The present utility model will be further described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.
[0024] Figures 2 to 3 An embodiment of the blister machine of the present utility model is shown. The blister machine of this embodiment includes a conveying mechanism 1. Along the conveying direction, the conveying mechanism 1 is successively provided with a bottle holder forming mechanism 2, a bottle body placing mechanism 3, and a film covering mechanism (not shown in the figure). A discharge leak detection mechanism 4 is also provided between the bottle body placing mechanism 3 and the film covering mechanism. The discharge leak detection mechanism 4 includes a transmitting electrode 42 and a receiving electrode 43 arranged at an interval up and down. A leak detection channel is formed between the transmitting electrode 42 and the receiving electrode 43. Among them, the conveying mechanism 1 may be, for example, a conveying roller.
[0025] In the blister machine of this embodiment, the PVC film material is conveyed through the conveying mechanism 1. When passing through the bottle holder forming mechanism 2, a bottle holder 51 is formed. When passing through the bottle body placing mechanism 3, as Figure 1 shown, the bottle body 52 is loaded into the bottle holder 51. Before the film covering mechanism covers the film on the bottle holder 51 containing the bottle body 52, discharge leak detection is first performed between the transmitting electrode 42 and the receiving electrode 43, so as to judge whether there is a broken bottle or whether there is a crack in the bottle wall, avoiding the adverse impact of film covering on detection. At the same time, compared with the commonly used visual detection, the discharge leak detection has better accuracy and reliability.
[0026] The discharge leak detection mechanism 4 further includes a power supply 41. The power supply 41 is respectively connected to the emitting electrode 42 and the receiving electrode 43. The emitting electrode 42 and / or the receiving electrode 43 is connected with a lifting driving member 44 (for example, it can be a cylinder, an electric cylinder or a synchronous belt mechanism, etc.). After the bottle holder 51 with the bottle body 52 reaches the leak detection channel, the emitting electrode 42 and / or the receiving electrode 43 moves up and down to contact the bottle holder 51, which is convenient for discharge detection. After the detection is completed, the emitting electrode 42 and / or the receiving electrode 43 resets, and the bottle holder 51 continues to be conveyed downstream. If the bottle body 52 in the bottle holder 51 is intact, it is covered with a film by the film covering mechanism, and then processes such as box loading are carried out; if there is a broken bottle or cracks in the bottle wall of the bottle body 52 in the bottle holder 51, it is removed to prevent unqualified products from being boxed and flowing into the market.
[0027] As a preferred embodiment, the emitting electrode 42 is located above the receiving electrode 43, and the lifting driving member 44 is connected to the emitting electrode 42, that is, the receiving electrode 43 remains stationary, and the lifting driving member 44 drives the emitting electrode 42 to move up and down to complete the detection. During the detection process, the bottle holder 51 does not need to move up and down, and the structure is reasonable and effective. Of course, in other embodiments, it can also be that the emitting electrode 42 remains stationary, the receiving electrode 43 moves up and down, or the emitting electrode 42 and the receiving electrode 43 move synchronously, approaching each other before detection and moving away from each other after the detection is completed.
[0028] As a preferred embodiment, a sampling resistor 45 is connected between the power supply 41 and the emitting electrode 42. The resistance value of the solution can be simulated through the sampling resistor 45 to make the detection result more accurate.
[0029] As a preferred embodiment, the emitting electrode 42 includes an emitting electrode sheet 421 and a plurality of needle tip parts 422 arranged on the emitting electrode sheet 421. The emitting electrode 42 is provided with a plurality of needle tip parts 422, which can be adapted to the uneven upper surface of the bottle holder 51, facilitating discharge detection.
[0030] As a preferred embodiment, the needle tip parts 422 are arranged on the lower surface of the emitting electrode sheet 421, and the receiving electrode 43 includes a receiving electrode sheet 431, and the receiving electrode sheet 431 is located below the needle tip parts 422. The receiving electrode sheet 431 located on the lower side is beneficial to provide stable support for the bottle holder 51, facilitating discharge detection.
[0031] See Figure 3 、 Figure 4 and Figure 5 , the discharge leak detection principle of the blister machine in this embodiment is as follows:
[0032] The power supply 41 preferably adopts an AC high-frequency power supply. The upper and lower sides of the bottle holder 51 are respectively connected to the emitting electrode 42 and the receiving electrode 43. Capacitance values C1 and C2 will be formed between the two electrodes and the bottle holder 51 (due to the partition of the bottle wall of the insulating glass bottle body 52 and the bottle holder 51 made of PVC material, the electrodes cannot contact the solution, so capacitance is generated). The sampling resistor 45 is the resistance value of the solution. When the bottle body 52 of the bottle holder 51 is intact, an induced microcurrent I1 is generated. When the bottle body 52 of the bottle holder 51 has cracks or is broken, and the liquid medicine leaks into the bottle holder 51 or there are cracks in the bottle wall, the capacitance between the bottle wall and the electrode disappears, the capacitive reactance generated by the capacitance is zero, and a larger microcurrent I2 is generated in the circuit. By comparing the magnitudes of the microcurrents, it can be determined whether the bottle body 52 leaks, and the leak detection accuracy is high.
[0033] Although the present utility model has been disclosed above with preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can, without departing from the scope of the technical solution of the present utility model, make many possible changes and modifications to the technical solution of the present utility model by using the above-disclosed technical content, or modify it into equivalent embodiments with equivalent changes. Therefore, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model shall fall within the scope of protection of the technical solution of the present utility model.
