Description

Technical Field

[0001] This utility model belongs to the field of auxiliary mechanisms for drug appearance inspection devices, and specifically relates to a rejection mechanism for drug appearance inspection devices. Background Technology

[0002] After pharmaceutical products complete final production, they require visual inspection to determine if they have any defects. Manual inspection of finished products, often done in 2-3 shifts with overtime, is inefficient and labor-intensive. While visual inspection devices can effectively replace manual inspection, an automated mechanism is still needed to remove defective products. Existing rejection mechanisms use swing-arm rejection systems, but these systems do not move with the defective products during removal, necessitating a reduction in the product transport speed. Therefore, a new rejection mechanism for pharmaceutical inspection is needed that can rapidly remove defective products during movement. Utility Model Content

[0003] This utility model is proposed to overcome the shortcomings of the existing technology, and its purpose is to provide a rejection mechanism for a drug appearance inspection device.

[0004] This utility model is achieved through the following technical solution:

[0006] In the above technical solution, the rejection mechanism for the drug appearance inspection device is installed above the conveyor belt of the transmission mechanism of the drug appearance inspection device through a rejection mechanism mounting component.

[0007] In the above technical solution, the waste rejection mechanism mounting component is an L-shaped structure composed of a mounting component crossbeam and a mounting component inclined beam connected to one end of the mounting component crossbeam. The mounting component inclined beam is fixedly connected to the upright plate of the drug appearance inspection device.

[0008] In the above technical solution, the adjustment structure includes a screw, a horizontal adjustment rod, a pair of guide rods, a rotating disk fixed to the top of the screw, and a copper nut fixed to the bottom of the screw.

A pair of guide rods are symmetrically arranged on both sides of the screw. One end of the guide rod passes through the mounting beam of the waste rejection mechanism and is fixedly connected to the top of the upper beam of the vacuum generator mounting frame. The horizontal adjustment rod is positioned above the mounting beam of the waste rejection mechanism and is bolted to the top of the guide rod.

[0009] In the above technical solution, a linear bearing is provided between the guide rod and the crossbeam of the mounting component of the waste rejection mechanism.

[0010] In the above technical solution, the horizontal adjusting rod is an Ω-shaped structure composed of a semi-circular ring and straight rods connected to both ends of the semi-circular ring. The semi-circular ring is sleeved outside the rotating disk, and the straight rods are connected to the guide rods.

[0011] In the above technical solution, the vacuum generator mounting bracket includes an upper mounting bracket and a lower mounting bracket.

[0013] The beneficial effects of this utility model are as follows: This utility model provides a rejection mechanism for a drug appearance inspection device. It is installed above the conveyor belt of the drug appearance inspection device, and its position and height are adjustable. It adopts the vacuum principle. The vacuum generator empties the air in the suction tube to form a vacuum environment, so that the tablets are sucked in and discharged. The rejection mechanism adopts the vacuum principle. When a rejection command is received, the corresponding rejection channel will open. The vacuum generator creates a vacuum state in the rejection channel, so that the tablets are sucked out and moved to the rejection collector. It innovatively adopts multiple rows of rejection ports. The suction range of each rejection port is larger than the pipe diameter to prevent missed rejection. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] like Figure 1 , 2 As shown, a rejection mechanism for a drug appearance inspection device includes a rejection mechanism mounting component 1, multiple vacuum generators 2, multiple rejection suction tubes 3, a vacuum generator mounting frame 4, and an adjustment structure 5; the rejection mechanism mounting component 1 is connected to the vacuum generator mounting frame 4 through the adjustment structure 5; the vacuum generators 2 are fixed on the vacuum generator mounting frame 4, and the rejection suction tubes 3 are connected to the vacuum generators 2.

[0028] The rejection mechanism for the drug appearance inspection device is installed above the conveyor belt of the transmission mechanism of the drug appearance inspection device via the rejection mechanism mounting part 1.

[0029] The waste rejection mechanism mounting component 1 is an L-shaped structure consisting of a mounting component crossbeam 11 and a mounting component inclined beam 12 connected to one end of the mounting component crossbeam 11. The mounting component inclined beam 12 is fixedly connected to the upright plate of the drug appearance inspection device.

[0030] The adjustment structure 5 includes a screw 51, a horizontal adjustment rod 56, a pair of guide rods 53, a rotating disk 52 fixed to the top of the screw 51, and a copper nut 54 fixed to the bottom of the screw 51.

[0031] The screw 51 passes through the mounting beam 11 of the waste removal mechanism mounting part 1 and the upper beam of the vacuum generator fixing frame 4 in sequence. The rotating disk 52 is placed above the mounting beam 11 of the waste removal mechanism mounting part 1. The copper nut 54 is placed below the upper beam of the vacuum generator fixing frame 4 and is fixedly connected to the upper beam of the vacuum generator fixing frame 4.

[0032] A pair of guide rods 53 are symmetrically arranged on both sides of the screw 51. One end of the guide rod 53 passes through the mounting beam 11 of the waste removal mechanism mounting part 1 and is fixedly connected to the top of the upper beam of the vacuum generator fixing frame 4. A linear bearing 55 is provided between the guide rod 53 and the mounting beam 11 of the waste removal mechanism mounting part 1. The horizontal adjustment rod 56 is placed above the mounting beam 11 of the waste removal mechanism mounting part 1 and is connected to the top of the guide rod 53 by bolts.

[0033] By rotating the rotating disk 52, the screw 51 is driven to rotate. The rotation of the screw 51 drives the copper nut 54 to move up and down along the screw 51, thereby driving the upper crossbeam of the vacuum generator fixing frame 4, which is fixed to the copper nut 54, to move up and down, thus realizing the adjustment of the height of the vacuum generator 2.

[0034] When the waste rejection inlet is not horizontal, the level can be adjusted by adjusting the bolts between the guide rod 53 and the horizontal adjustment rod 56 to ensure that the waste rejection inlet is parallel to the conveyor belt.

[0035] The horizontal adjustment rod 56 is an Ω-shaped structure consisting of a semi-circular ring and straight rods connected to both ends of the semi-circular ring. The semi-circular ring is set to avoid the operating space of the rotating disk 52, and the straight rods are connected to the guide rod 53.

[0036] The vacuum generator mounting bracket 4 includes an upper mounting bracket and a lower mounting bracket. The upper mounting bracket includes an upper crossbeam and inverted L-shaped vertical beams connected to both ends of the upper crossbeam. The lower mounting bracket includes a rectangular mounting plate and two front beams connected to the mounting plate. The front beams are located on the side away from the vacuum generator 2. The mounting plate is fixedly connected to the inverted L-shaped vertical beams. The vacuum generator 2 is connected to the mounting plate via corner brackets.

[0037] The removal tube 3 is equipped with a waste suction nozzle at its port, and the inner diameter of the waste suction nozzle is larger than the inner diameter of the removal tube 3.

[0038] Example 2

[0039] In this embodiment, the arrangement of the vacuum generator 2 in the rejection mechanism of the drug appearance inspection device is different from that in embodiment 1, while the rest are the same as in embodiment 1.

[0041] The upper fixing frame includes an upper crossbeam and rectangular vertical beams connected to both ends of the upper crossbeam;

[0042] The lower fixing frame is a rectangular frame structure, and the top surface of the lower fixing frame is fixedly connected to the bottom end of the vertical beam of the upper fixing frame.

[0043] The vacuum generator 2 is connected to the lower fixed frame via a corner bracket, and the vacuum generator 2 is located below the lower fixed frame.

[0044] The working principle of this utility model:

[0045] During the drug appearance inspection process, the inspection machine makes a judgment based on the comparison between the template and the material surface information, and gives and executes the rejection action. After receiving the instruction, the rejection mechanism gives and executes the rejection action. The vacuum generator works to empty the air in the rejection suction tube, forming a vacuum environment, so that the tablet is sucked in and discharged.
