Technical Field
[0001] This utility model relates to the field of empty bottle rejection equipment, specifically to an empty bottle detection alarm device for oral liquid filling machines. Background Technology
[0002] During the filling process of oral liquids, empty bottles may occur due to various uncontrollable factors. If the personnel fail to detect this in time, the empty bottles may flow into the next process and pose a risk of entering the market.
[0003] In the prior art, utility model patent application number CN202223128942.7 discloses an automatic empty bottle rejection device, including a feeding conveyor belt, a distributing turntable, a distributing base, a distributing trough, a discharging conveyor belt, a rejection seat, a chute, and a collection trough. The rejection seat is located on one side of the discharging conveyor belt, and a wedge-shaped rejection block is installed in the inner groove of the rejection seat. One end of the wedge-shaped rejection block with a wedge surface extends above the discharging conveyor belt, and the other end of the wedge-shaped rejection block is provided with a guide rod and a limiting block. A compressed spring is fitted on the guide rod. When the medicine bottle moves to the position of the wedge-shaped rejection block, due to the small friction between the empty bottle and the conveyor belt, it is pushed into the chute by the wedge-shaped rejection block and finally slides into the collection trough. Bottles filled with liquid medicine can squeeze the wedge-shaped rejection block and pass smoothly.
[0004] The aforementioned automatic empty bottle rejection equipment is greatly affected by the weight of the medicine bottle and the amount of medicine it contains. When the amount of medicine it contains changes or the model and weight of the medicine bottle change, it is necessary to repeatedly adjust the spring's pushing force on the wedge-shaped rejection block to achieve accurate rejection of the empty bottle. This is quite troublesome to use and needs improvement. Utility Model Content
[0005] The purpose of this invention is to provide an empty bottle detection alarm device for oral liquid filling machines, which can accurately reject empty bottles and is not affected by the weight of the bottles, thereby solving the defects mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An empty bottle detection alarm device for an oral liquid filling machine includes a support platform. A circular tray is fixedly installed on the top of the support platform. The tray has a feeding buffer channel with one end connected to it on its side wall, and a discharging buffer channel with one end also connected to it on its side wall. Above the tray is a feeding disc driven by a power device and rotating around its own axis. The edge of the feeding disc has an arc-shaped groove matching the medicine bottle. After the medicine bottle enters the tray through the feeding buffer channel, it moves towards the discharging buffer channel under the action of the feeding disc. A rejection port is provided on the side wall of the tray located between the feeding buffer channel and the discharging buffer channel. An arc-shaped plate is movably installed inside the rejection port. One end of the arc-shaped plate is rotatably connected to the side wall of the rejection port downstream along the direction of the medicine bottle's movement. The arc-shaped plate can rotate to the inside of the tray to open the rejection port, or rotate to form a complete circle with the side wall of the tray to seal the rejection port.
[0008] As a preferred technical solution, one end of the arc-shaped plate is provided with a protruding connecting part, and the side wall of the rejection port downstream along the movement direction of the medicine bottle is provided with a notch that matches the connecting part. A rotating shaft is fixedly installed on the connecting part, and the rotating shaft is rotatably installed on the tray. The rotating shaft is connected to a driving device.
[0009] As a preferred technical solution, an empty bottle detection device for identifying medicine bottles upstream of the rejection port is installed on the support platform; an alarm light is provided on the top of the empty bottle detection device; and an incoming material detection sensor is also installed on the side wall of the tray upstream of the empty bottle detection device.
[0010] As a preferred technical solution, a receiving plate is also fixedly installed on the outer side of the tray at the corresponding position of the rejection port, and the receiving plate is provided with upwardly extending side baffles on both sides along the width direction of the rejection port.
[0011] As a preferred technical solution, a connecting frame is fixedly installed on the receiving plate, and a drawer is slidably installed on the connecting frame, with one end of the drawer connected to one end of the receiving plate.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. When the empty bottle detection device detects an empty bottle, the drive motor drives the arc plate to rotate clockwise, causing one end to rotate into the tray and opening the rejection port. As the empty bottle moves with the feeding disc, it will gradually move out of the rejection port along the outer wall of the arc plate. After the rejection port is open and held for a preset time, the drive motor drives the arc plate to rotate counterclockwise to close the rejection port again. During the counterclockwise rotation of the arc plate to close, the empty bottle is further pushed out of the rejection port. The rejection of empty bottles is not affected by the weight of the medicine bottle, making the rejection of empty bottles more accurate.
[0014] 2. As more and more empty bottles are pushed onto the receiving plate by the curved plate, the empty bottles on the receiving plate gradually enter the drawer for collection. When the drawer is full of empty bottles, the drawer can be pulled out from the connecting frame for replacement, making the collection of empty bottles more convenient. Attached Figure Description

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1 to 4As shown, the empty bottle detection alarm device of the oral liquid filling machine includes a support platform 1. A circular tray 2 is fixedly installed on the top of the support platform 1 by bolts. A feeding buffer channel 3 with one end connected to the tray 2 is provided on the side wall of the tray 2. The feeding buffer channel 3 extends radially along the tray. A discharging buffer channel 4 with one end connected to the tray 2 is also provided on the side wall of the tray 2. The discharging buffer channel 4 extends tangentially along the tray 2. The ends of the feeding buffer channel 3 and the discharging buffer channel 4 away from the tray 2 are respectively connected to the feeding conveyor and the discharging conveyor.
[0023] The top of the support platform 1 is provided with an installation shaft 5 driven by a power device. The tray 2 is coaxially arranged with the installation shaft 5. The installation shaft 5 passes upward through the tray 2 and is coaxially fixedly installed with a feeding disc 6. The height of the feeding disc 6 is higher than the height of the tray 2. The edge of the feeding disc 6 is provided with an arc-shaped groove 7 that matches the medicine bottle. Multiple arc-shaped grooves 7 are evenly spaced around the circumference of the feeding disc 6.
[0024] The filled medicine bottles are continuously transported to the feeding buffer channel 3 by the feeding conveyor. As the feeding plate 6 rotates, the medicine bottles at the feeding buffer channel 3 enter the arc groove 7 on the edge of the feeding plate 6 one by one, and move along the inner wall of the tray 2 to the discharge buffer channel 4 under the drive of the feeding plate 6. The feeding plate 6 sends the medicine bottles out one by one to the discharge buffer channel 4, and finally the discharge conveyor transports the filled medicine bottles to the next process.
[0025] A rejection port 8 is provided on the side wall of the tray 2 located between the inlet buffer channel 3 and the outlet buffer channel 4. The bottom of the rejection port 8 is flush with the bottom of the tray 2, and the medicine bottles pass through the rejection port 8 when moving. An arc-shaped plate 9 is movably installed inside the rejection port 8, such as... Figure 4 As shown, one end of the arc-shaped plate 9 has an integrally formed protruding connecting part 10. A notch 11 matching the connecting part 10 is provided on the side wall of the removal port 8 downstream of the medicine bottle's movement direction. A rotating shaft 12 is embedded in the connecting part 10. The rotating shaft 12 extends vertically parallel to the axis of the tray 2 and is rotatably mounted on the side wall of the tray 2. Mounting holes matching the rotating shaft 12 are respectively provided on the side walls of the tray 2 located above and below the notch 11. The rotating shaft 12 is connected to a drive device, specifically a drive motor 13. The lower end of the rotating shaft 12 extends through the bottom of the tray 2 and is connected to the rotating shaft of the drive motor 13 via a coupling. The drive motor 13 is mounted on the front side of the support platform 1 by bolts.
[0026] The drive motor 13 drives the arc plate 9 to rotate clockwise, so that one end of it rotates into the inside of the tray 2, and the rejection port 8 is opened; or the drive motor 13 drives the arc plate 9 to rotate counterclockwise, so that the arc plate 9 rotates to form a complete circle with the side wall of the tray 2, thereby blocking the rejection port 8.
[0027] An empty bottle detection device 18 is installed on the support platform 1 to identify medicine bottles upstream of the rejection port 8; an alarm light 19 is provided on the top of the empty bottle detection device 18; and an incoming material detection sensor 20 is also installed on the side wall of the tray 2 located upstream of the empty bottle detection device 18.
[0028] The empty bottle detection device 18, alarm light 19, incoming material detection sensor 20, and drive motor 13 are all connected to the controller. Specifically, when the incoming material detection sensor 20 detects a medicine bottle passing by, the empty bottle detection device 18 identifies the bottle. The empty bottle detection device 18 can be a camera, which takes an image of the medicine bottle and uploads it to the controller to determine whether the bottle is empty. In the initial state, such as... Figure 2 As shown, when the rejection port 8 is closed, if the controller determines that the bottle is not empty, the drive motor 13 will not operate, and the medicine will smoothly pass through the rejection port 8 along the inner wall of the arc plate 9. If the controller determines that the bottle is empty, the alarm light 19 will flash to remind the staff, and at the same time, the drive motor 13 will rotate the arc plate 9 clockwise, causing one end to rotate into the tray 2 and opening the rejection port 8. Figure 3 As shown, the empty bottle moves along the outer wall of the arc plate 9 towards the rejection port 8 while following the feeding disc 6. After the rejection port 8 is opened and held for a preset time, the drive motor 13 drives the arc plate 9 to rotate counterclockwise to close the rejection port 8 again. During the counterclockwise rotation of the arc plate 9 to close, the empty bottle is further pushed out of the rejection port 8.
[0029] To facilitate the collection of rejected empty bottles, a receiving plate 14 is welded to the outer side of the tray 2 at the corresponding position of the rejection port 8. The top of the receiving plate 14 is flush with the bottom wall of the rejection port 8. After the arc plate 9 pushes the empty bottle out of the rejection port 8, the rejected empty bottle will move to the receiving plate 14 for temporary storage. The receiving plate 14 has integrally formed upward-extending side baffles 15 on both sides along the width direction of the rejection port 8 to prevent the empty bottle from falling from the side of the receiving plate 14.
[0030] The end of the receiving plate 14 furthest from the rejection port 8 is connected to an unloading conveyor. As the number of empty bottles on the receiving plate 14 increases, the unloading conveyor gradually transports the empty bottles on the receiving plate 14 to the next step for recycling; or as... Figure 4As shown, a connecting frame 16 is fixedly installed on the receiving plate 14. The connecting frame 16 is fixedly connected to the receiving plate 14 by screws. The connecting frame 16 is U-shaped. The receiving plate 14 and the two side baffles 15 are located inside the connecting frame 16. A drawer 17 is slidably installed on the connecting frame 16. Horizontally extending slide bars are provided on the inner sides of the opposite side walls of the connecting frame 16. Guide grooves matching the slide bars are provided on the left and right sides of the drawer 17. The top and rear ends of the drawer 17 are open. The rear end of the drawer 17 is connected to the front end of the receiving plate 14. As more and more empty bottles are pushed onto the receiving plate 14 by the arc plate 9, the empty bottles on the receiving plate 14 gradually enter the drawer 17 for collection. When the drawer is full of empty bottles, the drawer can be pulled out from the connecting frame 16 for replacement, making the collection of empty bottles more convenient.
