Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of conveying equipment, and in particular to a continuous conveying detection device and method for soft medicine bags. Background Art
[0002] In the pharmaceutical production process, soft medicine bags are a common form of pharmaceutical packaging, and the importance of quality inspection is self-evident. However, the existing soft medicine bag conveying and inspection equipment on the market has many problems that need to be solved, making it difficult to meet the needs of efficient and accurate production inspection.
[0003] Leakage monitoring of soft medicine bags is an important process after the production of soft medicine bags. During the inspection process, once the soft medicine bags leak, the surface of the limit tooling will become wet. However, existing equipment generally lacks effective drying measures. Will the wet limit tooling have an adverse effect on the subsequent adsorption and transportation of soft medicine bags? Usually, the machine is shut down for special drying treatment, which reduces the working efficiency and stability of the equipment. Summary of the Invention
[0004] In response to the above problems, the present invention provides a continuous conveying and detection device and method for soft medicine bags. In the invention, the pressure detection of the soft medicine bags and the surface drying of the limiting tooling can be carried out simultaneously, greatly improving the conveying efficiency and detection efficiency of the soft medicine bags.
[0005] In order to solve the above problems, the technical solution adopted by the present invention is: A continuous conveying and detection device and method for soft medicine bags include a conveying device and a detection device. A plurality of limiting toolings are provided on the surface of the conveying device. The conveying device includes an annular conveying belt. The limiting tooling is provided on the surface of the conveying belt. A negative pressure structure is provided on the upper end surface of the limiting tooling for adsorbing the soft medicine bag. The detection device is a pressure detection device, including a pressure detection end and a telescopic structure. The telescopic structure controls the pressure detection end to move toward the limiting tooling to complete the pressure detection of the soft medicine bag. A drying device is also provided on the outside of the conveying belt. During the rotation of the conveying belt, the corresponding limiting tooling is controlled to move relative to the drying device to complete the heating and drying of the limiting tooling.
[0006] During the testing process, the soft medicine bag on the surface of the second conveyor belt is moved by a robot to the limiting tooling on the surface of the conveyor belt. The soft medicine bag is limited by the limiting tooling. The soft medicine bag and the limiting tooling can move synchronously with the conveyor belt toward the testing device. At the testing device, the pressure detection end is controlled to move toward the limiting tooling, and the soft medicine bag is squeezed from both sides to complete the pressure test of the soft medicine bag.
[0007] After a very few soft medicine bags rupture, liquid leaks onto the surface of the limiting tooling. The wet limiting tooling affects the normal adsorption and storage of subsequent soft medicine bags. The corresponding limiting tooling is removed through the detection device, and then the corresponding limiting tooling is controlled to move to the side of the drying device to complete the drying of the residual liquid on the surface of the limiting tooling. Continuous residue on the surface affects the subsequent delivery and detection of soft medicine bags.
[0008] The soft medicine bags that pass the inspection can move synchronously with the limiting tooling. A first conveyor belt can be set at the lower end of the conveying device to control the limiting tooling to carry the soft medicine bags to move synchronously to one side of the first conveyor belt to complete the unloading and classification.
[0009] Preferably, the limiting tooling includes a plurality of limiting plates arranged in parallel, each of the limiting plates is respectively connected to the conveyor belt, the negative pressure structure is arranged on the surface of the limiting plate located in the middle, and a negative pressure pump body is also provided on the surface of the limiting plate.
[0010] The above structure can be installed on the surface of the conveyor belt, and at the same time, the surface of the soft medicine bag can be adsorbed by means of negative pressure limiting, thereby ensuring the stability of the soft medicine bag during movement.
[0011] Preferably, the upper end surface of the limiting plate is arc-shaped, and the plurality of limiting plates together form an arc-shaped limiting area adapted to the surface of the soft medicine bag.
[0012] By setting up the arc-shaped limiting area, the soft medicine bag can be adaptively limited and locked to ensure the stability of the soft medicine bag during transportation. The arc-shaped area can also collect liquid leaking from the bottom to prevent liquid overflow.
[0013] Preferably, the drying device includes a first drying component, which is arranged at the lower end of the conveyor belt. The first drying component includes a drying base and a retractable drying end. The upper end of the drying end is concave and has a built-in heating dryer.
[0014] The limiting tooling can be dried once by the first drying component, and the surface of the limiting tooling can be dried once by using hot air drying to avoid most of the liquid residue.
[0015] Preferably, the drying device includes a second drying component, which is arranged at the reversing point of the conveyor belt. The second drying component includes a drying hood mounted on the outside of the conveyor belt. The first side of the drying hood is connected to a hot air inlet pipe, and the second side of the drying hood is connected to a hot air outlet pipe. A drying channel is formed inside the drying hood for connecting the hot air inlet pipe and the hot air outlet pipe, and the hot air outlet pipe is opposite to the reversing point of the conveyor belt.
[0016] The second drying component can be used to further dry the surface of the limiting tooling, which is particularly suitable for this type of limiting tooling. When the limiting tooling moves to the reversing position, the gaps between the multiple limiting plates in the limiting tooling increase. At this time, the second drying component is used to blow air between the gaps between the multiple limiting plates, which can further enhance the drying of the residual liquid inside the limiting tooling and further effectively avoid liquid residue.
[0017] Preferably, the drying hood and the drying channel are both bent L-shaped, including a first drying section relatively parallel to the upper surface of the conveyor belt and a second drying section opposite to the reversing point of the conveyor belt, the hot air inlet pipe is opposite to the first drying section, and the hot air outlet pipe is located on the inner side of the second drying section.
[0018] Through the above structural design, the second drying component here can also dry the limiting tooling located at the upper end of the conveyor belt three times. The high-temperature hot air can efficiently dry the surface of the limiting tooling, thereby avoiding liquid residue on the surface of the limiting tooling to the greatest extent.
[0019] Preferably, a cooling assembly is also provided inside the drying hood, and the cooling assembly includes a cooling mounting plate, and a cooling part is provided on the lower end surface of the cooling mounting plate. The cooling part is located outside the moving path of the limiting tooling, and also includes a cooling telescopic rod for controlling the extension and retraction of the cooling mounting plate.
[0020] By setting up a cooling component, the surface of the limit tooling can be cooled to prevent the excessively high temperature of the limit tooling surface from affecting the subsequently placed soft medicine bags; the cooling part here can be filled with liquid cooling medium to achieve efficient heat dissipation. At the same time, it can also be connected to a pumping system to further enhance the cooling effect.
[0021] Preferably, the cross section of the cooling mounting plate is L-shaped, and the upper end surface of the drying hood is provided with a strip-shaped opening adapted to the cooling mounting plate.
[0022] Through the above structural design, the lowered cooling mounting plate can also form a sealing barrier on the outside, ensuring the relative avoidance of the drying channel in the direction of the cooling component, and ensuring the directional flow of internal hot air to achieve efficient drying.
[0023] Preferably, the detection terminal includes a detection base plate and a plurality of detection side plates, the plurality of detection side plates and the detection base plate together form a detection area, and a suction component connected to the detection area is provided on the surface of the detection terminal.
[0024] The detection base plate here protrudes outward, which can effectively squeeze and detect the soft medicine bags in the detection area. At the same time, a relatively closed area can be formed between the detection base plate and multiple detection side plates to avoid liquid leakage. When the amount of liquid leakage is large, the suction component can discharge the leaked liquid with excessive leakage to avoid affecting the surface of the conveying device, thereby ensuring the normal transportation and detection of the entire equipment and improving the efficiency of detection.
[0025] A method for continuously conveying and inspecting soft medicine bags, using the above-mentioned continuous conveying and inspecting soft medicine bags, comprises the following steps: S1, transferring the soft medicine bags to be inspected to the upper end of a limiting fixture on the surface of a conveyor belt, and implementing negative pressure limiting on the soft medicine bags by means of the limiting fixture; S2, driving the conveyor belt to cause the limiting fixture and the soft medicine bags to move in a directional manner to one side of a detection device to complete a pressure test; S3, after the inspection is completed, removing the soft medicine bags that fail the inspection from the surface of the conveyor belt, and marking the surface of the limiting fixture as being in a wet state; S4, controlling the wet limiting fixture to move to one side of a drying device to complete heating and drying of the limiting fixture.
[0026] The beneficial effects of the present invention are: Compared with the existing technology, the conveying device adopts an annular conveyor belt. This design enables the conveying process to be cyclical, thereby improving the conveying efficiency; multiple limiting fixtures are set on the surface of the conveyor belt to accurately position and limit the soft medicine bags, thereby ensuring the stability of the soft medicine bags during the conveying process; a negative pressure structure is set on the upper end surface of the limiting fixture, which adsorbs the soft medicine bags through negative pressure, further enhancing the stability of the soft medicine bags during the conveying process and preventing them from shifting and shaking; and the limiting fixture can be quickly dried by the drying device, and the pressure detection of the soft medicine bags and the surface drying of the limiting fixture can be carried out simultaneously, thereby greatly improving the conveying efficiency and detection efficiency of the soft medicine bags.

[0042] The drying device includes a first drying component and a second drying component.
[0043] First drying component: The first drying component 700 is arranged at the lower end of the conveyor belt, and includes a drying base 710 and a retractable drying end 720.

After the drying end 720 is extended, the limiting tooling 200 can be heated and dried during the rotation of the conveyor belt.
[0044] Second drying component: The second drying component 600 is arranged at the reversing point of the conveyor belt, and includes a drying hood 610 that is sleeved on the outside of the conveyor belt; the first side of the drying hood 610 is connected to the hot air inlet pipe 620, and the second side is connected to the hot air outlet pipe 612. A drying channel 611 is formed inside to connect the hot air inlet pipe 620 and the hot air outlet pipe 612, and the hot air outlet pipe 612 is opposite to the reversing point of the conveyor belt.
[0045] The drying hood 610 and the drying channel 611 are both bent L-shaped, including a first drying section relatively parallel to the upper surface of the conveyor belt and a second drying section opposite to the reversing point of the conveyor belt.
