Description

Technical Field

[0001] The present application relates to the technical field of pharmaceutical glass bottle production, and more specifically, to an annealing production line for pharmaceutical glass bottles. Background Art

[0002] Pharmaceutical glass bottles are important materials for storing and using drugs in the pharmaceutical industry. Their product quality is particularly important to the safety of drugs. Therefore, great care must be taken during the production process to avoid damage, defects or stress concentration. For example, in the production process of pharmaceutical vials, after the vials are formed, due to the high temperature of borosilicate glass, they will shrink and solidify when cooled. Unbalanced cooling or rapid cooling will cause stress in the glass, making it brittle or explode. Therefore, an annealing furnace is needed for temperature control to allow it to cool slowly, eliminate the stress generated during glass forming, and ensure the safety of the glass container.

[0003] Traditional pharmaceutical glass bottles are generally produced using the following process: vertical cillin bottle making machine → robot picking → conveyor belt → annealing furnace → defect detection → robot picking → manual sampling and packaging for storage. However, due to the flat surface of the conveyor belt, it is difficult to accurately position the cillin bottle on the conveyor belt during the robot lowering process, and random displacement will occur. At the same time, after entering the annealing furnace, the cillin bottle will also undergo secondary displacement due to the hot air flow (≥590°) in the annealing furnace. Displacement is very likely to cause collisions between bottles, causing damage and scratches.

[0004] In the existing annealing equipment for medicinal glass bottles, a mesh belt or a pillow plate is often used to position the glass bottles. For example, in Chinese Patent 201920420387.4, a medicinal glass annealing equipment is disclosed, which uses a stainless steel mesh belt to set a medicinal glass bottle placement rack, and vertically places the medicinal glass bottles by setting structures such as a diamond steel plate mesh and a limit ring. Although it can stabilize the medicinal glass bottles and prevent them from displacement, the stainless steel mesh belt structure places very high demands on the accuracy of glass bottle placement. Ordinary manipulators (especially simple suction cup manipulators) are difficult to achieve precise placement, so it is easy for the glass bottles to fall off or be inaccurately placed. The former still causes the displacement and collision of the glass bottles, and the latter will cause the actual placement of the glass bottles to be disorderly (for example, the glass bottles are arranged in random mesh positions in the grid), which will cause difficulties for subsequent defect detection and robot picking, which not only affects the qualified rate of medicinal glass bottles, but also limits production efficiency. Summary of the invention

[0005] The present application provides a medicinal glass bottle annealing production line to solve the problem that during the annealing process of medicinal glass bottles in the prior art, the glass bottles are prone to displacement and collision, and are arranged in a disorderly manner, making subsequent inspection and picking difficult, and easily causing the conveyor belt to get stuck, thereby affecting production efficiency.

[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present application.

Thus, the exemplary term "above" may include both "above" and "below".

[0034] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0035] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0036] Taking borosilicate glass vials as an example, they are high-level controlled injection pharmaceutical packaging bottles, and are generally used as packaging bottles for vaccines, biological preparations, powder injections, freeze-dried powders and other drugs. The neck of the bottle is thinner, and the thickness below the neck is uniform. The mouth of the bottle is slightly thicker than the neck and slightly thinner than the bottle body. Due to the stress problem of glass, the vial needs to be annealed, and collisions should be avoided during the annealing process. Because the neck of the vial is thinner and the length is shorter, it is difficult to grasp accurately. Therefore, before annealing to eliminate stress, it is usually handled in a more stable way (such as suction cup suction) to ensure the success rate of grasping and avoid damage. This results in poor grasping accuracy of the robot, which can easily cause the messy placement of pharmaceutical glass bottles during the annealing process, affecting the annealing effect and the subsequent inspection and picking and transportation process. In addition, for production lines that use grids or pillows to position glass bottles, since the bottle mouth must be strictly engaged with the grid or pillow when placing, when there is an error in the accuracy of the robot, it is easy to cause the fragile bottle mouth to hit the metal grid or pillow during the placement process, causing damage to the glass bottle and causing waste of production costs. To address this problem, the present application proposes a medicinal glass bottle annealing production line that can avoid collisions during the glass bottle annealing process, while reducing the robot's pick-and-place accuracy requirements and facilitating subsequent inspection and picking.

[0037] Figures 1 to 5 The annealing production line for medicinal glass bottles shown in Example 1 of the present application is shown.

[0038] like Figures 1 to 5 As shown, the present application discloses a medicinal glass bottle annealing production line, including: a loading manipulator 1, an automatic conveying device 2, an annealing furnace 3, a detection device 4 and a picking manipulator 5. Among them, the automatic conveying device 2 includes: a conveying component 21, the conveying component 21 includes a conveying chain 211, the conveying chain 211 runs through the annealing furnace 3, the starting end of which corresponds to the loading manipulator 1, and the end of which corresponds to the picking manipulator 5. A bearing component 22, the bearing component 22 is arranged on the conveying chain 211, and moves with the conveying chain 211. The bearing component 22 is provided with a placement groove 221 perpendicular to the conveying direction, and each placement groove 221 is arranged at intervals from each other and arranged in a straight line, and a medicinal glass bottle 6 is placed horizontally in each placement groove 221. A sorting component 23, the sorting component 23 is arranged on the side of the conveying component 21, and includes a pushing mechanism, which can extend into the bearing component 22 to push the medicinal glass bottles 6 in each placement groove 221 to the specified position.

[0039] Through the above structural design, the present application sets the bearing assembly 22 and uses the placement groove 221 set along the vertical transmission direction to horizontally place the medicinal glass bottle 6, which can effectively prevent the medicinal glass bottle 6 from rolling during the transmission process. At the same time, with the help of the sorting assembly 23, the medicinal glass bottle 6 is pushed and positioned after entering the groove, and the neat and straight arrangement of the medicinal glass bottles 6 can be achieved without improving the placement accuracy of the manipulator, so as to facilitate the subsequent detection of the detection device 4 and the picking and handling of the picking manipulator 5, thereby reducing the jamming problem of the conveying chain 211, which not only ensures the quality and safety of the medicinal glass bottles 6, but also maintains stable production and ensures production efficiency.

[0040] In the embodiment of the present application, it can be understood by those skilled in the art that the loading manipulator 1 is used to place the medicinal glass bottle 6 on the carrying component 22; the detection device 4 is used to detect whether the medicinal glass bottle 6 in a horizontal state on the carrying component 22 has defects such as broken ports; and the picking manipulator 5 is used to retrieve the medicinal glass bottle 6 from the carrying component 22. Since the carrying component 22 of the embodiment of the present application is provided with placement grooves arranged in a straight line, and is provided with a sorting component 23 for pushing and positioning the medicinal glass bottle 6, the medicinal glass bottle 6 can be accurately positioned and maintained in a straight line input and output. Thereby, it is conducive to the subsequent detection device 4 and the picking manipulator 5 to perform detection and picking at a fixed position, avoiding the occurrence of missed detection and picking failure due to the disorderly position of the medicinal glass bottle 6, so as to reduce the failure stagnation rate of the production line and improve production efficiency.

[0041] In some embodiments of the present application, Figures 2 to 4 As shown, two rows of placement grooves 221 are symmetrically arranged on the bearing assembly 22. The two rows of placement grooves 221 are arranged back to back with the groove openings facing outwards. A protruding positioning plate 222 is arranged on one side close to each other (see Figure 3 ). There are two groups of sorting components 23 symmetrically arranged, and the two groups of sorting components 23 are separated on both sides of the conveying component 21. The pushing mechanism of the sorting component 23 pushes the medicinal glass bottle 6 to the designated position by pushing the medicinal glass bottle 6 to the contact positioning plate 222. Thus, through the pushing mechanism of the sorting component 23, the two rows of medicinal glass bottles 6 can be automatically arranged neatly along the positioning plate 222, so as to contact the heated airflow in the annealing furnace 3, so that the annealing is sufficient, and the hidden danger of the physical and chemical properties of the glass not meeting the standards is effectively eliminated. Moreover, in this embodiment, the medicinal glass bottles 6 are neatly arranged along a straight line, which ensures the stability of the position while facilitating the subsequent port defect detection and automatic transportation at the designated position. The problem of missed detection and failure of the picking robot 5 to grasp due to the disorderly discharge of the medicinal glass bottles 6 (such as the problem of multiple picking at different positions) will not occur, thereby avoiding transmission jams, ensuring orderly and stable production, and improving production efficiency.

[0042] In the embodiments of the present application, Figures 2 to 4As shown, a conveyor chain 211 corresponds to two rows of placement slots 221, and two groups of sorting components 23 arranged on both sides of the conveyor chain 211 are used to push and sort. Compared with the traditional mesh structure conveyor belt, the structure of the present application is simpler and more convenient to manage. It can significantly reduce the difficulty of taking and positioning the medicinal glass bottles 6 during the annealing process, significantly reduce the probability of error and shutdown in the automated production process, and improve the efficiency of automated production.

[0043] In the embodiment of the present application, based on the above settings, Figure 4 As shown, the width of the annealing furnace 3 is several times that of the automatic conveyor 2, and multiple automatic conveyors 2 can be arranged in parallel and pass through the annealing furnace 3 together. Thus, by breaking the whole into parts, the traditional disorderly mesh-like placement of the medicinal glass bottles 6 is changed into a straight line form of two rows in a group, making the transportation process through the annealing furnace 3 simpler and easier to control, and the placement of the medicinal glass bottles 6 is neatened, which is beneficial to improving the annealing effect, avoiding the problems of missed inspection and picking failure, and improving the efficiency of automated production.

[0044] In some embodiments of the present application, Figure 2 , Figure 3 and Figure 5 As shown, the pushing mechanism of the sorting component 23 includes: a driving unit (not shown), a push rod 231 and a push plate 232. The output end of the driving unit is connected to the push rod 231, and the push plate 232 is installed at the end of the push rod 231. The push plate 232 contacts and pushes the medicinal glass bottle 6. In addition, the sorting component 23 also includes: a controller (not shown), an inductive start switch 233 and a contact stop switch 234. The inductive start switch 233 and the contact stop switch 234 are set in linkage with the driving unit through the controller. The inductive start switch 233 is set on the travel path of the medicinal glass bottle 6. When the inductive start switch 233 counts a preset number of medicinal glass bottles 6, the controller controls the driving unit to drive the push plate 232 to move. The contact stop switch 234 is set on the travel path of the push plate 232. After the contact stop switch 234 senses the extrusion of the push plate 232, the controller controls the driving unit to drive the push plate 232 to reset. By providing a controller, an induction start switch 233 and a contact thrust switch 234, the medicinal glass bottles 6 can be automatically and safely sorted, without the need for manual bottle placement and without damaging the bottle bodies during the pushing and sorting process.

[0045] In some embodiments of the present application, Figure 3 and Figure 5 As shown, the finishing assembly 23 also includes: an adjustment mechanism, which includes: a screw rod 235 and an adjustment motor (not shown), the screw rod 235 is installed at the output end of the adjustment motor and is driven by the adjustment motor. The adjustment motor is electrically connected to the controller and receives the command control of the controller. Figure 5As shown, the contact thrust switch 234 is mounted on the screw rod 235 and is threadedly connected to the screw rod 235. The controller controls the rotation of the adjustment motor according to the input command to change the distance between the contact thrust switch 234 and the positioning plate 222, so as to match the pharmaceutical glass bottles 6 of different sizes. By setting the adjustment mechanism, the embodiment of the present application can conveniently adjust the size according to the different batches of the produced pharmaceutical glass bottles 6, thereby improving the adaptability of the annealing production line of the present application. Specifically, in Figure 5 In the illustrated embodiment, two groups of contact thrust switches 234 are provided corresponding to the two rows of placement slots 221, and the two groups of contact thrust switches 234 are connected to the screw rod 235 through opposite threads, so that the controller only needs to control the rotation of one screw rod 235 to adjust the push stop position of the placement slots 221 on both sides, simplifying the control structure and meeting the production requirements of different sizes of medicinal glass bottles 6. Among them, the two ends of the screw rod 235 are rotatably fixed by bearings and can be suspended above the conveying chain 211 upstream of the annealing furnace 3. The contact thrust switch 234 thereon is installed downward and extends into the travel path of the push plate 232 for contact sensing, so as not to interfere with the conveying movement of the conveying chain 211.

[0046] In some embodiments of the present application, Figure 3 As shown, the induction start switch 233 is an infrared radiation switch, which is arranged on both sides of the travel path of the placement slot 221. When the medicinal glass bottle 6 carried in the placement slot 221 passes, the induction start switch 233 notifies the controller by counting (such as 5), so that the controller starts the driving unit to drive the push rod 231 and the push plate 232 to do a horizontal push motion, thereby pushing the medicinal glass bottle 6 to the designated position of the placement slot 221 and close to the positioning plate 222. Among them, the final position of the push plate 232 movement is determined by the contact stop thrust switch 234. When the push plate 232 touches the contact stop thrust switch 234, the controller controls the push rod 231 to retract and reset the push plate 232. The position of the contact stop thrust switch 234 can be adjusted by the adjustment mechanism so that its distance relative to the positioning plate 222 is just equal to the length of the medicinal glass bottle 6, thereby accurately and safely realizing the positioning and sorting of the medicinal glass bottle 6.

[0047] In some embodiments of the present application, Figure 3 As shown, the length of the push plate 232 covers a plurality of (eg, 5) placement slots 221, and can simultaneously push the medicinal glass bottles 6 in a plurality of placement slots 221 to improve the pushing and sorting efficiency.

[0048] In some embodiments of the present application, Figures 1 to 4 As shown, the placement groove 221 is a V-shaped structure, which can ensure that the bottle body is clamped and fixed by the inclined surfaces on both sides so that it will not roll, thereby keeping the bottle body relatively stable.

[0049] In addition, if Figure 6As shown, in the second embodiment of the present application, the placement groove 221 can also be set to be inclined at a preset angle to the horizontal. For example, it is inclined upward at a preset angle from the positioning plate 222, so as to facilitate the sliding of the medicinal glass bottle 6 to the positioning plate 222 and keep the medicinal glass bottle 6 from being easily displaced in the left and right axial directions.

[0050] In some embodiments of the present application, continue as Figure 6 As shown, the positioning plate 222 is provided with a circular turntable 2221 corresponding to each placement slot 221, and a driving gear 2222 is connected inside the circular turntable 2221, and the driving gear 2222 is exposed from the bottom of the positioning plate 222. The position of the conveying component 21 corresponding to the detection device 4 is the detection area, and the detection area is provided with a fixed rack (not shown), which is fixed in the middle of the conveyor belt. When the bearing component 22 passes through the detection area, the driving gear 2222 meshes with the fixed rack, thereby driving the circular turntable 2221 and the medicinal glass bottle 6 in contact therewith to rotate, so that the detection device 4 can more comprehensively detect the port defects of the medicinal glass bottle 6, and reduce the occurrence of unqualified product leakage.

[0051] In some embodiments of the present application, the support assembly 22 is provided with a tray, and each placement slot 221 is provided on the tray. When the medicinal glass bottle 6 is broken due to stress, the tray can collect the glass fragments to prevent the glass fragments from falling into the annealing furnace 3 and other equipment, thereby protecting the safety of the production line. The broken glass can be collected at the end of the conveyor chain 211 and other locations. Figures 2 to 4 In the structure shown, part of the housing and the tray structure of the bearing assembly 22 are hidden and not shown in the figure, but those skilled in the art can understand the arrangement method, as long as there is a tray structure and it avoids interference with the conveyor chain 211. For example, strip steel plates can be stacked and spliced ​​to form a tray structure that can bend and move with the conveyor chain 211.

[0052] In some embodiments of the present application, the loading robot 1 and the picking robot 5 are both suction cup robots, including a vacuum mechanism and one or more suction cups, and the suction cups adsorb the bottle body position of the medicinal glass bottle 6 for grabbing. By grabbing the bottle body position with the suction cup, it is possible to avoid excessive squeezing of the stressed medicinal glass bottle 6, and reduce the loss of the medicinal glass bottle 6 during the picking and placing process. At the same time, the bottle body picking and placing is more suitable for horizontally placed medicinal glass bottles 6, so that they can fully contact the heated airflow in the annealing furnace 3, so that annealing is sufficient. In addition, the suction cup robot has a simple structure and low cost, and the structural design of the automatic conveying device 2 of the present application can push and arrange the medicinal glass bottles 6 through the sorting component 23, so that they are automatically arranged neatly, reducing the pick-and-place accuracy requirements for the robot, thereby effectively controlling the procurement cost of the loading robot 1 and the picking robot 5, which is conducive to improving the economic benefits of the production line.

[0053] In some embodiments of the present application, the detection device 4 is a visual detection device, which uses a pre-trained image database to identify defects by taking photos and videos, so as to quickly and accurately detect defects. Figure 6 The positioning plate 222 with a turntable 2221 and a driving gear 2222 shown can make the medicinal glass bottle 6 in the placement slot 221 rotate automatically in the detection area, thereby avoiding missing defects caused by angle problems and improving detection accuracy.

[0054] In summary, the annealing production line for medicinal glass bottles of the present application includes: a loading robot, an automatic conveying device, an annealing furnace, a detection device and a picking robot; wherein the automatic conveying device includes: a conveying component, the conveying component includes a conveying chain, the conveying chain runs through the annealing furnace, the starting end of the conveying chain corresponds to the loading robot, and the end corresponds to the picking robot; a bearing component, the bearing component is arranged on the conveying chain and moves with the conveying chain, and the bearing component is provided with placement grooves perpendicular to the conveying direction, the placement grooves are arranged at intervals from each other and arranged in a straight line, and a medicinal glass bottle is placed horizontally in each placement groove; a sorting component, the sorting component is arranged on the side of the conveying component, and includes a pushing mechanism, and the pushing mechanism can extend into the bearing component to push the medicinal glass bottles in each placement groove to the specified position. The present application sets a bearing component and utilizes a placement groove set along the vertical conveying direction to horizontally place the medicinal glass bottles, which can effectively prevent the medicinal glass bottles from rolling during the conveying process. At the same time, with the help of a sorting component, the medicinal glass bottles are pushed and positioned after entering the groove. This can achieve a neat and straight arrangement of the medicinal glass bottles without improving the placement accuracy of the robot, so as to facilitate the subsequent detection by the detection device and the picking and transportation by the picking robot, thereby reducing the problem of conveying chain jamming, which not only ensures the quality and safety of the medicinal glass bottles, but also maintains production stability and ensures production efficiency.
