Abstract
Description
Technical Field
[0001] This utility model relates to the field of butyl rubber stoppers, specifically to a butyl rubber stopper surface defect detection and sorting device. Background Technology
[0002] Butyl rubber stoppers are a commonly used pharmaceutical packaging material, mainly used to seal medicine bottles. Due to the properties of butyl rubber, butyl rubber stoppers have good airtightness, chemical stability and elasticity, which can effectively prevent drugs from contacting the external environment and maintain the quality and shelf life of the drugs.
[0003] During the production of butyl rubber stoppers, surface defect detection is required to screen out substandard stoppers. Existing surface defect detection technologies for butyl rubber stoppers include a surface defect sorting device for butyl rubber stoppers (publication number CN221335495U). This device, in operation, uses limit protrusions and a motor. The limit protrusions on the upper and lower conveyor belts limit the stoppers, preventing them from shaking or tilting. Simultaneously, the stoppers are blown off by the action of two blow pipes, all driven by a single motor. This reduces costs and improves the practicality of the sorting device. However, in actual use, to ensure that the blowing pipe 1 and the discharge pipe 2 can effectively blow the butyl rubber stoppers off the upper and lower conveyor belts, the limiting protrusions cannot be designed to be too thick and need to be designed to be relatively thin. However, the relatively thin limiting protrusions cannot effectively limit the butyl rubber stoppers during transportation. When the butyl rubber stoppers are transported by the upper and lower conveyor belts, there is an inevitable risk that the butyl rubber stoppers will fall off. Therefore, we propose a butyl rubber stopper surface defect detection and sorting device. Utility Model Content

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.
[0015] Reference Figure 1 - Figure 5 This utility model discloses a butyl rubber stopper surface defect detection and sorting device, comprising a frame 1, a material distribution assembly 2 fixedly installed on the frame 1, two sets of material pushing assemblies 3 installed on the frame 1, two sets of upper conveying rollers 4 and two sets of lower conveying rollers 5 rotatably mounted on the frame 1 via bearings, an upper conveyor belt 6 sleeved on the outer side of the two sets of upper conveying rollers 4, and a lower conveyor belt 7 sleeved on the outer side of the two sets of lower conveying rollers 5. The material distribution assembly 2, in conjunction with the upper conveyor belts 6 and the lower conveyor belts 7, sorts and conveys the butyl rubber stoppers.
[0016] The material distribution assembly 2 includes four sets of horizontal plates 201. Both ends of the four sets of horizontal plates 201 are fixedly connected to the frame 1. The two upper sets of horizontal plates 201 are fixedly connected to upper partition 1 202, upper partition 203, and upper partition 3 204. The bottoms of upper partition 1 202, upper partition 203, and upper partition 3 204 are slidably attached to the upper conveyor belt 6. The two lower sets of horizontal plates 201 are fixedly connected to lower partition 1 205 and lower partition 2 206. 6 and lower partition 3 207, the bottom of lower partition 1 205, lower partition 206 and lower partition 3 207 are all slidably attached to the lower conveyor belt 7, and the lower partition 3 207 is provided with a discharge port 20701; the upper conveyor belt 6 is divided into two conveying areas by upper partition 1 202, upper partition 203 and upper partition 3 204, and the upper conveyor belt 6 is divided into two conveying areas by lower partition 1 205, lower partition 206 and lower partition 3 207.
[0017] A mounting plate 8 is fixedly installed on the frame 1, and a speed reducer 9 is fixedly installed on the mounting plate 8. The drive end of the speed reducer 9 is fixedly connected to a set of lower conveyor rollers 5 through a coupling. When in use, starting the speed reducer 9 will drive the set of lower conveyor rollers 5 connected to it to rotate, which in turn can drive the lower conveyor belt 7 to carry out conveying work.
[0018] A stabilizing frame 10 is fixedly installed on the frame 1. A rotating shaft 11 is rotatably connected to the stabilizing frame 10 via bearings. A set of gears 12 is fixedly installed on the outer wall of the rotating shaft 11 and on the outer wall of a set of upper conveying rollers 4, respectively. The two sets of gears 12 mesh with each other. A set of sprockets 13 is fixedly installed on the outer wall of the rotating shaft 11 and on the outer wall of a set of lower conveying rollers 5, respectively. Both sets of sprockets 13 mesh with chains 14. The reducer 9 drives the lower conveying rollers 5 connected to it to rotate. Under the transmission of the two sets of sprockets 13 and chains 14, the reducer 9 drives the rotating shaft 11 to rotate. The rotating shaft 11 rotates and, under the transmission of the two sets of meshing gears 12, drives the upper conveying rollers 4 to rotate. This drives the upper conveyor belt 6 to perform conveying work. The lower conveyor belt 7 and the upper conveyor belt 6 have opposite conveying directions. The upper conveyor belt 6 conveys from a position away from the flip tube 19 to a position closer to the flip tube 19.
[0019] The pushing assembly 3 includes a hydraulic cylinder 301. The telescopic end of the hydraulic cylinder 301 is fixedly connected to the pushing frame 302. The pushing frame 302 is fixedly connected to a baffle plate 303 and two sets of guide rods 304. The hydraulic cylinder 301 is fixedly installed on the frame 1. Both sets of guide rods 304 slide through the inner side of the frame 1. In use, starting the hydraulic cylinder 301 can drive the pushing frame 302 to move, and the guide rods 304 make the pushing frame 302 move stably. It should be noted that when the two sets of hydraulic cylinders 301 in the two pushing assemblies 3 are used separately, they need to be used together with a dedicated hydraulic pump, hydraulic pipeline, etc., and the hydraulic pump and its controller need to be connected to a suitable external power supply. The bottom of the pushing frame 302 and the baffle plate 303 in the upper pushing assembly 3 slides against the upper conveyor belt 6, and the bottom of the pushing frame 302 and the baffle plate 303 in the lower pushing assembly 3 slides against the lower conveyor belt 7.
[0020] The frame 1 is fixedly equipped with an upper frame 15 and a lower frame 16. An upper detection lens 17 is fixedly installed on the upper frame 15, and a lower detection lens 18 is fixedly installed on the lower frame 16. The detection system is triggered by a phototube. After receiving a signal, the upper detection lens 17 and the lower detection lens 18 capture images and transmit them to the industrial control computer. The industrial control computer makes a result based on the image processing software and sends the result signal to the PLC through the I / O board. Finally, after receiving the result signal, the PLC sends a rejection signal to the two sets of pusher components 3 through shift control. The two sets of pusher components 3 push the defective products to the appropriate conveying area, and the qualified and unqualified butyl rubber stoppers are collected separately.
[0021] A flipping tube 19 is fixedly installed between the upper partition 1 202, upper partition 2 203, lower partition 1 205, and lower partition 2 206. A feeding tube 20 is fixedly installed between the upper partition 2 203, upper partition 3 204, lower partition 2 206, and lower partition 3 207. Both the flipping tube 19 and the feeding tube 20 slide against the upper conveyor belt 6 and the lower conveyor belt 7. Butyl rubber stoppers that pass the crown inspection in the area between the upper partition 1 202 and upper partition 2 203 will enter the flipping tube 19, flip, and then enter the area between the lower partition 1 205 and lower partition 2 206 for conveying. The neck of the rubber stopper is inspected by the lower inspection lens 18. Butyl rubber stoppers that fail the inspection between the upper partition 2 203 and upper partition 3 204 will enter the area between the lower partition 2 206 and lower partition 3 207 for conveying through the feeding tube 20.
[0022] The working principle of this utility model is as follows: When in use, the reducer 9 is started to drive the lower conveyor belt 7 and the upper conveyor belt 6 to transport in opposite directions. The upper conveyor belt 6 is transported from a position away from the flip tube 19 to a position close to the flip tube 19. At the same time, the external vibrating plate feeds the butyl rubber stoppers that need to be inspected and sorted into the upper conveyor belt 6 through the external linear feeder. The stoppers are placed between the upper partition 1 202 and the upper partition 2 203. The butyl rubber stoppers are inspected below the upper inspection lens 17. The butyl rubber stoppers that fail the inspection of the crown will be pushed into the space between the upper partition 2 203 and the upper partition 3 204 by the pusher assembly 3 at the upper position. Butyl rubber stoppers that pass the crown inspection in the area between upper partition 1 202 and upper partition 2 203 will enter the flipping tube 19, flip it, and then enter the area between lower partition 1 205 and lower partition 2 206 for conveying. The neck of the rubber stopper will be inspected by the lower inspection lens 18. Butyl rubber stoppers that fail the inspection between upper partition 2 203 and upper partition 3 204 will enter the area between lower partition 2 206 and lower partition 3 207 through the feed pipe 20. Butyl rubber stoppers conveyed between lower partition 1 205 and lower partition 2 206 are inspected at the neck level below the lower inspection lens 18. Butyl rubber stoppers with qualified necks are conveyed to the end of the lower conveyor belt 7, where they are collected. Butyl rubber stoppers with unqualified necks are pushed between lower partition 2 206 and lower partition 3 207 by the pusher assembly 3 and pushed into the discharge port 20701. The unqualified butyl rubber stoppers between lower partition 2 206 and lower partition 3 207 are conveyed by the lower conveyor belt 7 and eventually discharged from the discharge port 20701. Thus, all unqualified butyl rubber stoppers are discharged from the discharge port 20701, facilitating their collection.
[0023] It should be noted that when using the reducer 9, it needs to be connected to a suitable external power supply in conjunction with its dedicated controller, and its operation is controlled by the controller.
[0024] The above description provides a more detailed explanation of the present invention in conjunction with specific embodiments. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present invention.
