Description

Technical Field

[0001] This utility model belongs to the field of medicine bottle inspection equipment, specifically relating to a novel visual inspection device for medicine bottle trays. Background Technology

[0002] After the coding and printing process, ampoules and similar medicine bottles are typically placed in plastic trays for packaging. Before packaging, to ensure quality, the medicine bottles in the trays need to be inspected. Existing inspection devices generally use visual inspection lenses to photograph and identify trays with missing bottles, missing lettering, or faintly printed characters. Current inspection devices typically use cylinders or air guns to remove substandard trays from the conveyor belt. The medicine bottles can then be cleaned and recycled. However, because the trays are transported at high speed on the conveyor belt, problems such as flying or broken bottles frequently occur when the trays are removed from the conveyor belt using cylinders or similar structures, resulting in discarded medicine bottles. This not only affects the operation of the production line but also causes significant waste. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model aims to provide a novel visual inspection device for medicine bottle trays. This device can efficiently inspect trays containing medicine bottles, accurately rejecting trays with missing bottles or substandard printing, and effectively preventing issues such as bottles flying or breaking during tray removal.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A novel visual inspection device for medicine bottle trays includes a frame and a visual inspection lens. A first conveyor belt and a second conveyor belt are horizontally mounted on the frame. The visual inspection lens is mounted above the first conveyor belt. A discharge port is provided on one side of the first conveyor belt behind the visual inspection lens, and the second conveyor belt is located at the discharge port. A waste removal mechanism is provided above the two conveyor belts. The waste removal mechanism pushes unqualified medicine bottle trays on the first conveyor belt onto the second conveyor belt through the discharge port. The tail end of the second conveyor belt is connected to a waste bin on the frame, and a storage lifting mechanism is vertically installed in the waste bin.

[0006] Preferably, the first conveyor belt is a transparent conveyor belt, and a lighting lamp is installed on the bottom of the transparent conveyor belt facing upwards.

[0007] Preferably, a first photoelectric switch is installed on one side of the first conveyor belt at a position corresponding to the visual inspection lens.

[0008] Preferably, the second conveyor belt is installed parallel to the side of the first conveyor belt, and the two conveyor belts have the same material conveying direction;

[0009] Preferably, the waste removal mechanism includes a synchronous belt drive assembly and a push rod. The synchronous belt drive assembly is horizontally inclined and installed above the two conveyor belts along the feeding direction, and the push rod is fixedly connected to the synchronous belt drive assembly.

[0010] Preferably, the synchronous belt drive assembly includes multiple horizontal synchronous belts that are arranged side by side and rotate synchronously. The push rod is vertically fixed to the surface of the horizontal synchronous belt, and the push rods on different horizontal synchronous belts are arranged at an angle. When the push rod rotates to the bottom of the synchronous belt, the arrangement direction of the push rod is parallel to the material conveying direction of the two drive belts.

[0011] Preferably, the waste bin is vertically mounted on the frame, and a feed inlet connected to the second conveyor is provided on one side of the opening at the top of the waste bin; the material storage lifting mechanism includes a synchronous belt lifting assembly, which includes a pallet and a lifting synchronous belt, the pallet being movably mounted in the waste bin, and the pallet being fixedly connected to the vertically mounted lifting synchronous belt.

[0012] Preferably, the material lifting mechanism further includes a slide rail vertically installed in the waste bin, and the pallet is vertically slidably installed on the slide rail.

[0013] Preferably, a second photoelectric switch and a third photoelectric switch for detecting material level are installed above and below the waste bin, respectively.

[0014] Preferably, a plurality of limiting rods are vertically fixed at the opening of the waste bin to limit the movement of the rising box support.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The first photoelectric switch of this utility model is used to detect when a box tray passes by on the first conveyor belt. When the visual inspection lens is activated, it takes a picture and detects the box tray. Since the first conveyor belt is transparent, the lighting below can shine through the first conveyor belt onto the plastic box tray, thereby illuminating the glass medicine bottle. This allows the visual inspection lens to effectively identify and detect the printing quality of the characters on the medicine bottle.

[0017] 2. When the visual inspection lens detects a problem with the packaging or printing of medicine bottles on the high-speed conveyor belt, the tray will be rejected by the synchronous belt drive assembly at the discharge port. During this process, because the synchronous belt drive assembly is set at a certain angle to the two conveyor belts, and the three push rods are parallel to the first drive belt below the three horizontal synchronous belts, the movement of the horizontal synchronous belts can obliquely push the problematic tray towards the discharge port via the three push rods. This causes the tray to move laterally towards the discharge port while moving along the conveyor belt's conveying direction. The tray moves at high speed on the conveyor belt. Compared to the existing technology that uses cylinders or air guns to vertically push / blow and reject the tray, the horizontally inclined waste rejection mechanism in this application provides smoother tray movement during screening, effectively avoiding problems such as flying or broken bottles during tray movement, ensuring the integrity of the medicine bottles in the screened trays, and enabling the bottles to be recycled.

[0018] 3. Problematic box trays rejected by the waste rejection mechanism are conveyed to a pallet in the waste bin via the second conveyor belt. After loading onto the pallet, it is detected by the second photoelectric switch above, triggering the lifting synchronous belt to lower the pallet by one station. This creates a gap of one box tray's height between the waste bin's inlet and the top of the pallet, preparing for the next loading. This process is repeated after each loading into the waste bin until the third photoelectric switch below detects the material level. At this point, the touch panel and warning lights will prompt the operator to retrieve the material. Once the operator initiates the unloading operation, the lifting synchronous belt will raise the pallet to its maximum height, lifting the entire material stored in the waste bin. After the operator retrieves the material, the lifting synchronous belt lowers the pallet back to its top station, ready for further processing.

[0019] 4. Multiple limit rods are vertically fixed at the opening of the waste bin. The limit rods can effectively limit the box tray that is pushed out of the waste bin to prevent it from tipping over. Attached Figure Description

[0026] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of application of this utility model.

[0027] like Figure 1-6 As shown, this utility model proposes a novel visual inspection device for medicine bottle trays, including a frame 1 and a visual inspection lens 13. The frame 1 is equipped with a transparent outer shell 11 for easy observation of the device's operation. A human-machine interface touch panel 12 is installed on the outer shell 41, which integrates a PLC control system for regulating and displaying the operating status and parameters of components such as the conveyor belt, motor, and photoelectric switch. A first conveyor belt 2 and a second conveyor belt 3 are horizontally mounted on the frame 1, and the visual inspection lens 13 is installed above the first conveyor belt 2.

[0028] The tray containing the medicine bottles is typically made of translucent plastic. In this application, the first conveyor belt 2 is transparent, and an upward-facing light is installed below the transparent conveyor belt, opposite the visual inspection lens 13. A first photoelectric switch is installed on one side of the first conveyor belt 2, corresponding to the visual inspection lens 13. The first photoelectric switch is used to activate the visual inspection lens 13 to take a picture when it detects a tray passing over the first conveyor belt 2. Because the first conveyor belt 2 is transparent, the light below it can shine through the first conveyor belt 2 onto the plastic tray, thus illuminating the glass medicine bottle, enabling the visual inspection lens 13 to effectively identify and detect the printing quality of the characters on the medicine bottle. The visual inspection lens 13 used in this application is a commonly used inspection lens 13 in the prior art, and its principle will not be elaborated further.

[0029] A discharge port is provided on one side of the first conveyor belt 2 behind the vision inspection lens 13. The second conveyor belt 3 is located at the discharge port and is installed parallel to the side of the first conveyor belt 2. The two conveyor belts have the same material conveying direction. A transition plate 14 is fixedly provided in the gap between the two conveyor belts.

[0030] A waste rejection mechanism 4 is provided above the two conveyor belts. This mechanism removes defective loading trays from the first conveyor belt 2 and transfers them to the second conveyor belt 3 through the discharge port. A baffle plate 31 is provided on the side of the second conveyor belt 3 away from the discharge port to limit the trays being conveyed laterally onto the second conveyor belt 3. Specifically, the waste rejection mechanism 4 includes a synchronous belt drive assembly and push rods 43. The synchronous belt drive assembly is horizontally inclined above the two conveyor belts along their feeding direction. The synchronous belt drive assembly includes three horizontal synchronous belts 42 horizontally mounted on the housing 41. The three horizontal synchronous belts 42 are arranged side-by-side and synchronously driven by the same motor. Each horizontal synchronous belt 42 has a push rod 43 vertically fixed to its surface, and the push rods 43 on different horizontal synchronous belts 42 are arranged at an angle relative to the lateral direction of the belt. When the push rods 43 rotate to the bottom of the synchronous belt, their arrangement direction is parallel to the feeding direction of the two conveyor belts.

[0031] When the visual inspection lens 13 detects a problem with the tray or printing on the medicine bottle being conveyed at high speed on the first conveyor belt 2, the tray will be rejected from the discharge port by the synchronous belt drive assembly. During this process, because the synchronous belt drive assembly is set at a certain angle to the two conveyor belts, and the three push rods 43 are parallel to the first drive belt below the three horizontal synchronous belts 42, when the horizontal synchronous belts 42 move, they can obliquely push the problematic tray towards the discharge port through the three push rods 43, causing the tray to move along the conveying direction of the first conveyor belt 2 while pushing it laterally towards the discharge port.

[0032] The box tray moves at high speed when conveyed on the conveyor belt. Compared with the prior art of vertically pushing / blowing to remove materials by cylinders or air guns, the waste removal mechanism 4 set horizontally in this application makes the movement of the box tray more stable during screening and unloading. It effectively avoids problems such as flying bottles and broken bottles during the movement of the box tray, ensures the integrity of the medicine bottles in the box tray after screening, and enables the medicine bottles to be recycled.

[0033] The waste bin 5 is vertically mounted on the frame 1. A feed inlet 50, connected to the second conveyor, is located on one side of the top opening of the waste bin 5. An upper limit plate 51 is horizontally mounted on the side of the top opening of the waste bin 5 away from the feed inlet 50. The feed inlet 50 is positioned at a height lower than the upper limit plate 51. One end of the upper limit plate 51 is horizontally hinged to the side wall of the waste bin 5 opening. During normal operation, it is horizontal and serves to limit the movement of trays entering the waste bin 5, preventing trays or medicine bottles from flying out of the waste bin 5 opening. The waste bin 5 can be rotated open when unloading is required.

[0034] A material lifting mechanism is vertically installed inside the waste bin 5. This mechanism includes a motor-driven synchronous belt lifting assembly and a slide rail 54 vertically installed inside the waste bin 5. The synchronous belt lifting assembly includes a support plate 53 and a lifting synchronous belt 55. The support plate 53 is vertically movable within the waste bin 5 and slides vertically on the slide rail 54. The support plate 53 is fixedly connected to the vertically installed lifting synchronous belt 55. A second photoelectric switch and a third photoelectric switch for detecting material levels are installed above and below the waste bin 5, respectively.

[0035] The problematic box trays rejected by the waste rejection mechanism 4 are conveyed to the pallet 53 in the waste bin 5 via the second conveyor belt 3. After the material is loaded onto the pallet 53, it is detected by the second photoelectric switch above. The lifting synchronous belt 55 is activated, which drives the pallet 53 to descend one station, leaving a space of one box tray height between the feed inlet 50 of the waste bin 5 and the top box tray of the pallet 53, in preparation for the next feeding. After each feeding, the waste bin 5 repeats the above actions until the third photoelectric switch below detects the material level. At this time, the touch panel 12 and the warning light will prompt the staff to pick up the material. After the staff starts the unloading operation, the lifting synchronous belt 55 will drive the pallet 53 to rise to the maximum height, thereby lifting out the entire material stored in the waste bin 5. After the staff picks it up, the lifting synchronous belt 55 drives the pallet 53 to descend and reset to the top station to wait.

[0036] Multiple limiting rods 52 are vertically fixed at the opening of the waste bin 5. The limiting rods 52 can effectively limit the box tray that is pushed out of the waste bin 5, so as to prevent the box tray from tipping over after it is pushed out.

[0037] When using this utility model, the visual inspection lens 13 will effectively inspect the box trays conveyed on the first conveyor belt 2. The qualified box trays are sent to the next process via the first conveyor belt 2. The unqualified box trays will be rejected from the discharge port by the synchronous belt drive assembly and sent to the second conveyor belt. The second conveyor belt will send them to the pallet 53 in the waste bin 5. Each time the waste bin 5 is fed, the lifting synchronous belt 55 will drive the pallet 53 to descend one station to prepare for the next feeding.
