Flexible vibrating disc and special-shaped bottle filling and sealing system

Abstract

This utility model discloses a flexible vibratory feeder with a flexible sealing sleeve covering the base and mounting seat. This prevents vibration drive from contaminating the material tray through the gap between the base and mounting seat, improving the aseptic properties of the material tray and making it suitable for aseptic environments. The material tray is also detachable for offline sterilization. This utility model also discloses a flexible vibratory feeder that can adjust the posture of irregularly shaped bottles to facilitate gripping by the first transfer mechanism. For irregularly shaped bottles with significant differences in width between the front and side, a second transfer mechanism performs horizontal and vertical rotation to adjust the vertical conveying direction of the wider side, allowing the narrower side of the bottle to occupy the conveying position. Finally, a pitch-changing device reduces the pitch, increasing the number of irregularly shaped bottles that can be buffered and conveyed, thus improving conveying efficiency.

Description

Technical Field

[0001] This utility model relates to the field of food and pharmaceutical packaging equipment technology, specifically to a flexible vibratory feeder and a filling system for irregularly shaped bottles. Background Technology

[0002] Patent CN119456466A discloses a flexible feeding and sorting machine, which uses a flexible vibrating plate to vibrate materials for visual recognition, and then sorts and transfers them by a robotic arm. However, there is a gap between the flexible vibrating plate and the vibration drive component in this flexible feeding and sorting machine, which does not meet the sterility requirements. Furthermore, the flexible vibrating plate is inconvenient to disassemble and assemble, which increases the difficulty of sterilization.

[0003] Patent CN222498630U discloses a stoppering and capping device for eye drops. Eye drops are usually irregularly shaped bottles with significant differences in width parameters between the front and the side. If the wider front is always in the conveying direction during transport, the number of bottles that can be transported with the same conveying line length will be reduced, thereby reducing the processing efficiency of subsequent processes.

[0005] This utility model further provides a bottle filling and sealing system that adjusts the conveying posture of irregularly shaped bottles and increases the number of irregularly shaped bottles conveyed by a transfer mechanism.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A flexible vibratory feeder includes a base and a flexible sealing sleeve. The base contains a vibration drive, and a mounting seat is provided above the vibration drive. A material tray is detachably provided on the mounting seat. A transparent plate is provided below the material tray on the mounting seat, and a light source is provided below the transparent plate. The flexible sealing sleeve is fitted over the base and the mounting seat, and both ends of the flexible sealing sleeve are connected to the base and the mounting seat respectively. A heat dissipation part is provided at the bottom of the base.

[0007] As a further improvement to the above technical solution: Both the outer side of the base and the outer side of the mounting seat are provided with flexible sealing sleeve mounting grooves. The protruding edge of the flexible sealing sleeve is installed in the flexible sealing sleeve mounting groove, and the inner end face of the protruding edge is connected to the flexible sealing sleeve mounting groove.

[0008] The top surface of the transparent plate is flush with the top surface of the mounting base and abuts against the bottom surface of the material tray.

[0009] The vibration drive is located at both ends of the mounting base.

[0010] The mounting base is provided with a positioning pressure plate at one end and a quick-release pressure plate at the other end. The outer side of the material tray is provided with a flange. One end of the flange is locked in the positioning pressure plate, and the other end is pressed by the quick-release pressure plate.

[0011] A shaped bottle filling and sealing system includes a first transfer mechanism, a second transfer mechanism, a third transfer mechanism, a first conveyor line, a second conveyor line, and the aforementioned flexible vibrating plate. The first conveyor line is located on one side of the flexible vibrating plate. The first transfer mechanism is used to transfer the shaped bottles placed horizontally in the flexible vibrating plate to the first conveyor line. A pitch-changing device is provided between the output end of the first conveyor line and the input end of the second conveyor line. The second transfer mechanism is used to change the shaped bottles placed horizontally on the first conveyor line to vertical and adjust the placement angle so that the shaped bottles are placed into the pitch-changing device with their wide side perpendicular to the conveying direction. The third transfer mechanism is used to place the shaped bottles on the pitch-changing device onto the second conveyor line. The output end of the second conveyor line is connected to the filling and sealing device.

[0012] As a further improvement to the above technical solution: The irregular bottle filling system also includes a material unpacking device and a bottle body buffer hopper. The material unpacking device is used to unpack the bag, and the output port of the bottle body buffer hopper is located above the flexible vibrating plate.

[0013] The irregular bottle filling system also includes a position detector, which is used to detect the position and orientation of the irregular bottle in the tray. The position detector is electrically connected to the first transfer mechanism.

[0014] The second conveyor line is a reciprocating conveyor belt, and an empty tray detection and waste rejection device is installed on one side of the second conveyor line.

[0015] The filling and sealing device includes, in sequence, an air washing device, a liquid filling device, a stoppering device, a first inspection and rejection device, a capping device, a second inspection and rejection device, and a good product output device. A bottle feeding mechanism is provided between the second conveyor line and the air washing device, and a bottle unloading mechanism is provided between the second inspection and rejection device and the good product output device.

[0034] Example 1 Figures 1 to 4 This invention illustrates an embodiment of the flexible vibratory feeder. The flexible vibratory feeder of this embodiment includes a base 1 and a flexible sealing sleeve 7. A vibration drive 2 is provided inside the base 1, and a mounting seat 3 is provided above the vibration drive 2. A material tray 5 is detachably provided on the mounting seat 3. A transparent plate 4 is provided below the material tray 5 on the mounting seat 3, and a light source 6 is provided below the transparent plate 4. The flexible sealing sleeve 7 is sleeved on the base 1 and the mounting seat 3, and both ends of the flexible sealing sleeve 7 are connected to the base 1 and the mounting seat 3 respectively. A heat dissipation part 41 is provided at the bottom of the base 1.

[0035] The flexible vibratory feeder has a material tray 5 for placing irregularly shaped bottles 20. The vibration drive 2 drives the mounting base 3 to vibrate, thereby causing the material tray 5 to vibrate and adjusting the posture of the irregularly shaped bottles 20. At the same time, the light source 6 illuminates the irregularly shaped bottles 20 in the material tray 5 through the transparent plate 4, which facilitates the subsequent gripping and transfer of the irregularly shaped bottles 20. In addition, the whole is cooled and routed through the heat dissipation part 41.

[0036] The flexible vibratory plate has a flexible sealing sleeve 7 covering the base 1 and the mounting base 3. The two ends of the flexible sealing sleeve 7 are connected to the base 1 and the mounting base 3 respectively, which prevents the vibration drive 2 from contaminating the material tray 5 through the gap between the base 1 and the mounting base 3, improves the sterility of the material tray 5, makes it suitable for sterile environments, and the material tray 5 is detachable for offline sterilization.

[0037] Furthermore, such as Figure 1 and Figure 2 As shown, in this embodiment, both the outer side of the base 1 and the outer side of the mounting base 3 are provided with flexible sealing sleeve mounting grooves 8. The protruding edge 71 of the flexible sealing sleeve 7 is installed in the flexible sealing sleeve mounting groove 8, and the inner end face of the protruding edge 71 abuts against the flexible sealing sleeve mounting groove 8. The flexible sealing sleeve mounting groove 8 facilitates the installation of the flexible sealing sleeve 7 and further improves the sealing performance. The flexible material of the flexible sealing sleeve 7 can adapt to the pulling during vibration and avoid affecting the vibration material handling. Preferably, the inner end face of the protruding edge 71 is bonded to the flexible sealing sleeve mounting groove 8 to improve the sealing performance.

[0038] Furthermore, such as Figure 1As shown, in this embodiment, the top surface of the transparent plate 4 is flush with the top surface of the mounting base 3 and abuts against the bottom surface of the tray 5. The transparent plate 4 provides support for the tray 5, resulting in higher stability.

[0039] Furthermore, such as Figure 1 As shown, in this embodiment, the vibration drive 2 is located at both ends of the mounting base 3. The vibration is more balanced, which helps to improve the material handling effect.

[0040] Furthermore, such as Figure 1 and Figure 3 As shown in this embodiment, the mounting base 3 has a positioning pressure plate 91 at one end and a quick-release pressure plate 92 at the other end. The outer side of the material tray 5 has a flange 51, one end of which is engaged in the positioning pressure plate 91, and the other end is pressed by the quick-release pressure plate 92. During installation, one end of the flange 51 of the material tray 5 is engaged in the positioning pressure plate 91, then the quick-release pressure plate 92 is engaged in the other end of the flange 51, and finally the quick-release pressure plate 92 is locked onto the mounting base 3. This allows for quick assembly and disassembly of the material tray 5, facilitating offline sterilization of the material tray 5.

[0041] Example 2 Figures 5 to 11 An embodiment of the irregular bottle filling system of this utility model is shown. The irregular bottle filling system of this embodiment includes a first transfer mechanism 10, a second transfer mechanism 11, a third transfer mechanism 12, a first conveyor line 13, a second conveyor line 14, and the aforementioned flexible vibrating plate. The first conveyor line 13 is located on one side of the flexible vibrating plate. The first transfer mechanism 10 is used to transfer the irregular bottle 20 placed horizontally in the flexible vibrating plate to the first conveyor line 13. A pitch-changing device 15 is provided between the output end of the first conveyor line 13 and the input end of the second conveyor line 14. The second transfer mechanism 11 is used to change the irregular bottle 20 placed horizontally on the first conveyor line 13 to vertical and adjust the placement angle so that the irregular bottle 20 is placed into the pitch-changing device 15 with the wide side perpendicular to the conveying direction. The third transfer mechanism 12 is used to place the irregular bottle 20 on the pitch-changing device 15 onto the second conveyor line 14. The output end of the second conveyor line 14 is connected to the filling device 16.

[0042] The filling process of this irregularly shaped bottle filling system is as follows: A flexible vibrating plate adjusts the posture of the irregularly shaped bottle 20, at which point the irregularly shaped bottle 20 is placed horizontally (e.g., Figure 11 As shown in Figure A), it is then transferred to the first conveyor line 13 via the first transfer mechanism 10 for conveying (as shown in Figure A). Figure 11 As shown in Figure B), when the irregularly shaped bottle 20, which is placed horizontally on the first conveyor line 13, is conveyed to the output end of the first conveyor line 13, the second transfer mechanism 11 changes the horizontally placed irregularly shaped bottle 20 on the first conveyor line 13 into a vertical position (as shown in Figure B). Figure 11 (As shown in C) and adjust the placement angle so that the irregularly shaped bottle 20 is placed into the pitch-changing device 15 with its wide side perpendicular to the conveying direction (as shown in C). Figure 11 As shown in Figure D), the pitch-changing device 15 reduces the pitch of the irregularly shaped bottle 20 (as shown in Figure D). Figure 11 (As shown in E), then the third transfer mechanism 12 places the irregular bottle 20 on the pitch device 15 onto the second conveyor line 14, and the second conveyor line 14 transports the irregular bottle 20 to the filling device 16 for filling.

[0043] In this irregular bottle filling system, the flexible vibratory feeder can adjust the posture of the irregular bottle 20, making it easier for the first transfer mechanism 10 to grasp it. For irregular bottles 20 with large differences in width between the front and side, the second transfer mechanism 11 can rotate them horizontally and vertically to adjust the vertical conveying direction of the wide side, so that the narrow side of the irregular bottle 20 occupies the conveying position. Finally, the pitch is reduced by the pitch-changing device 15, which can increase the number of irregular bottles 20 that can be buffered and conveyed, and improve the conveying efficiency.

[0044] Furthermore, such as Figure 4 and Figure 6 As shown, in this embodiment, the irregular-shaped bottle filling system also includes a material unpacking device 17 and a bottle buffer hopper 18. The material unpacking device 17 is used to unpack the bag, and the output port of the bottle buffer hopper 18 is located above the flexible vibrating plate. After the bottle packaging material is cleaned by the material unpacking device 17 and the inner packaging bag is removed, it is poured into the bottle buffer hopper 18 and then added to the material tray 5 of the flexible vibrating plate through the output port. Preferably, multiple sets of the material unpacking device 17, the bottle buffer hopper 18, the flexible vibrating plate, and the first transfer mechanism 10 are provided and arranged at intervals along the conveying direction of the first conveying line 13 to improve the feeding efficiency of the irregular-shaped bottles 20.

[0045] Furthermore, such as Figure 4 As shown, in this embodiment, the irregular-shaped bottle filling system also includes a position detector 19. The position detector 19 is used to detect the position and orientation of the irregular-shaped bottle 20 in the tray 5. The position detector 19 is electrically connected to the first transfer mechanism 10. The position detector 19 detects the orientation and position of the irregular-shaped bottle 20 in the tray 5, so that the first transfer mechanism 10 can accurately grasp it.

[0046] Furthermore, such as Figure 5 and Figure 7 As shown in the figure, in this embodiment, the second conveyor line 14 is a reciprocating conveyor belt, and an empty tray detection and rejection device is provided on one side of the second conveyor line 14. The empty tray detection and rejection device (not shown in the figure) detects whether there are irregularly shaped bottles 20 in the bottle trays conveyed by the second conveyor line 14 to the filling device 16, and rejects empty trays to ensure that the downstream filling device 16 continues to feed, does not empty, and produces full bottles, thereby improving the filling efficiency. The trays that have been unloaded and the rejected empty trays are returned to the feeding end of the second conveyor line 14 to continue conveying bottles. Furthermore, such as Figures 8 to 10As shown, in this embodiment, the filling and sealing device 16 includes an air washing device 21, a liquid filling device 22, a stoppering device 23, a first inspection and rejection device 24, a capping device 25, a second inspection and rejection device 26, and a good product output device 27 arranged in sequence. A bottle feeding mechanism 28 is provided between the second conveyor line 14 and the air washing device 21. A bottle unloading mechanism 29 is provided between the second inspection and rejection device 26 and the good product output device 27. The stoppering device 23 includes a stopper feeding mechanism 30, a stopper buffer hopper 31, a stopper sorting mechanism 32, a stopper separating mechanism 33, and a stopper pressing mechanism 34 arranged in sequence. The capping device 25 includes a cap feeding mechanism 35, a cap buffer hopper 36, a cap sorting mechanism 37, a cap separating mechanism 38, a pre-capping mechanism 39, and a capping mechanism 40. The bottle feeding mechanism 28 transfers the irregularly shaped bottles 20 on the second conveyor line 14 to the air washing device 21 for air washing. After air washing, the bottles pass through the liquid filling device 22, the stoppering device 23, the first inspection and rejection device 24, the capping device 25, and the second inspection and rejection device 26 for liquid filling, stoppering, inspection and rejection after stoppering, capping, and inspection and rejection after capping. Finally, the bottle unloading mechanism 29 transfers the good products to the good product output device 27 for output.

Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention.
