Abstract
Description
Technical Field
[0001] This invention relates to the field of controlled bottle manufacturing technology, and in particular to a device for testing controlled bottles. Background Technology
[0002] During the production of tubular bottles, the formed tubular bottles need to be inspected to remove those with quality defects such as dirt, bubbles or cracks, or those that do not meet the size requirements. Only qualified tubular bottles that meet the quality and size requirements are retained and then transported to the next process.
[0003] The existing controlled bottle inspection equipment places the controlled bottle to be inspected on two support rollers during inspection. The pressure roller then drives the controlled bottle to rotate on the two support rollers through contact with the controlled bottle. Multiple camera groups facing the bottle body, bottle mouth, and bottle bottom collect image information during the rotation of the controlled bottle and identify quality defects such as dirt, bubbles, or cracks based on the image information.
[0004] However, due to the limitations of the controlled bottles themselves and the equipment, existing controlled bottle testing equipment is prone to random back-and-forth movement along the axial direction during the testing process. This problem is particularly pronounced when the controlled bottle rotates at a high speed. This not only increases the risk of the controlled bottle falling off the testing station but also affects the testing results. Summary of the Invention

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.
[0031] The technical solutions disclosed in the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0032] Please refer to Figures 1 to 6 As shown, this embodiment of the invention discloses a device for detecting controlled bottles, which includes a support base 100, an auxiliary mechanism 200, and a limiting part 300. The support base 100 is provided with a first support part 101 and a second support part 102 for rotation, and the first support part 101 and the second support part 102 form a detection station for supporting the rotation of the controlled bottle 103. The limiting part 300 is provided on the side of the controlled bottle facing the bottom of the controlled bottle at the detection station, or on the side of the controlled bottle facing the mouth of the controlled bottle at the detection station. The auxiliary mechanism 200 is provided at a position adjacent to the detection station, and the controlled bottle at the detection station is moved to the limiting part 300 under the action of the auxiliary mechanism 200.
[0033] Therefore, by using the auxiliary mechanism 200, the control bottle 103 at the testing station moves uniformly in the direction of the limiting part 300 during its rotation and cooperates with the limiting part 300 to limit it. This solves the problem that the control bottle 103 at the testing station is prone to random back-and-forth movement in the axial direction due to the control bottle itself and the equipment during its rotation. This avoids the risk of the control bottle 103 falling off the testing station due to excessive movement and keeps the control bottle 103 in an effective testing position to ensure the testing effect.
[0034] The existing equipment for inspecting controlled bottles uses camera units and other image acquisition units that can only detect and identify quality defects such as dirt, bubbles or cracks on the bottom of the bottle, but cannot obtain information such as the thickness of the bottom of the bottle, the unevenness of the inner surface of the bottom, or the unevenness of the outer surface of the bottom.
[0035] In response to this, the device for detecting controlled bottles disclosed in this embodiment can also be equipped with a detection sensor 400, which is positioned facing the bottom of the controlled bottle at the detection station. Thus, during the rotation of the controlled bottle 103, the detection sensor 400 completes the detection of multiple points on the bottom of the bottle, and obtains the surface unevenness information and / or thickness information of the bottom of the controlled bottle based on the distance between the inner and outer surfaces of each point on the bottom of the controlled bottle and the detection sensor 400.
[0036] Typically, the detection sensor 400 can be a spectral confocal displacement sensor. During detection, the detection sensor emits a light beam at a specific point on the bottom of the controlled bottle. The emitted light beam is reflected at both the inner and outer surfaces of the bottom of the controlled bottle and is received by the detection sensor. The detection sensor determines the distance S1 between the outer surface of the bottom of the controlled bottle and the detection sensor based on the reflected light from the outer surface of the bottom of the controlled bottle. The detection sensor determines the distance S2 between the inner surface of the bottom of the controlled bottle and the detection sensor based on the reflected light from the inner surface of the bottom of the controlled bottle. Finally, the thickness of the bottom of the controlled bottle at that point is determined based on the distance difference ΔS(S2-S1) between the inner and outer surfaces.
[0037] Therefore, based on the distance S1 between multiple points detected by the detection sensor at the bottom of the controlled bottle, the unevenness information of the outer surface of the bottom of the controlled bottle can be obtained; based on the distance S2 between multiple points detected by the detection sensor at the bottom of the controlled bottle, the unevenness information of the inner surface of the bottom of the controlled bottle can be obtained; and based on the distance difference ΔS between multiple points detected by the detection sensor at the bottom of the controlled bottle, the thickness information of the bottom of the controlled bottle can be obtained.
[0038] It should be noted that when the limiting part 300 is located on the side facing the bottom of the control bottle, in order to prevent the limiting part 300 from blocking the detection light of the detection sensor 400, the limiting part 300 is provided with a clearance structure that allows the detection sensor 400 to illuminate the bottom of the control bottle, such as a gap, through hole, or notch. At the same time, in order to ensure the reliability of the detection sensor 400 in detecting the unevenness information of the inner and outer surfaces of the bottom of the control bottle, it should be performed after the control bottle 103 is in limiting engagement with the limiting part 300. When the detection sensor 400 detects the thickness information of the bottom of the control bottle, it can be performed either during the movement of the control bottle 103 toward the limiting part 300 or after the control bottle 103 is in limiting engagement with the limiting part 300.
[0039] The auxiliary mechanism 200 disclosed in this embodiment can be a fan structure, so that the rotating control bottle at the detection station can be blown towards the limiting part 300 by the wind without contacting the control bottle; or, the auxiliary mechanism 200 can be a push rod or push plate structure, so that the control bottle can be pushed towards the limiting part 300 by the pushing force of the push rod or push plate.
[0040] However, the auxiliary mechanism 200 is primarily a guide structure positioned above the testing station. After the guide structure contacts and engages with the control bottle, the rotating control bottle moves towards the limiting part 300 under the action of the guide structure. Furthermore, the guide structure located above the control bottle can also solve the problem of the control bottle bouncing up and down during its rotation, thus making the rotation and movement of the control bottle more stable and reliable compared to a fan structure. Its structure is as follows:
[0041] The auxiliary mechanism 200 may include a guide and a base 220. The base 220 serves as the mounting base for the guide and is used to connect with the equipment frame. The guide is disposed on the base 220 and located above the inspection station. The guide is used to contact and cooperate with the control bottle at the inspection station. The direction of the guide is at an acute angle to the rotation axis of the control bottle at the inspection station (i.e., the direction of the guide is oblique to the rotation axis of the control bottle). Thus, during the rotation of the control bottle, the guide contacts and cooperates with the control bottle and can generate a component force along the axis of the control bottle, causing the control bottle to move to the position where it is limited and cooperates with the limiting part 300.
[0042] It is easy to understand that, in order to achieve the rotation of the control bottle at the inspection station, the guide part can be connected to a drive mechanism such as a motor, or the first support part 101 or the second support part 102 can be connected to a drive mechanism such as a motor. In this way, the drive mechanism such as a motor can drive the guide part, the first support part 101 or the second support part 102 to rotate the control bottle 103 at the inspection station. At the same time, in order to enable the detection sensor 400 to collect multiple points in a spiral distribution at different radii on the bottom of the bottle to further improve the accuracy of the detection results, the following possible implementation methods can be adopted.
[0043] As a first possible implementation, the guide can be an elastic structural component, such as a rubber belt or elastic band with good elasticity; the support base 100 is provided with a lifting module 110. After the control bottle at the detection station comes into contact with the guide, the lifting module 110 controls the control bottle at the detection station to rise and push the guide. Under the adaptive elastic deformation of the guide, the control bottle 103 rotating at the detection station is kept in contact with the guide and moves upward past the detection position of the detection sensor 400. This allows the detection sensor 400 to detect multiple points in a spiral distribution in different radius areas of the bottom of the control bottle, thereby better ensuring the accuracy of the detection results.
[0044] The rubber belt or elastic band can be fixedly mounted on the base 220 at both ends. The first support part 101 or the second support part 102 is equipped with a drive mechanism, which drives the first support part 101 or the second support part 102 to rotate, thereby causing the control bottle 103 at the testing station to rotate. Alternatively, the rubber belt or elastic band can be looped around the driving wheel 230 and the driven wheel 240 of the base 220, with the driving wheel 230 equipped with a drive mechanism. This drive mechanism drives the rubber belt or elastic band to circulate via the driving wheel 230, thereby causing the control bottle 103 at the testing station to rotate.
[0045] As a second possible implementation, the support base 100 is provided with a lifting module 110, and the auxiliary mechanism 200 is provided with a moving structure. The moving structure can be provided at the connection between the guide part and the base 220, that is, the guide part is connected to the base 220 through the moving structure, so that the guide part can move relative to the base 220 through the adaptive function of the moving structure; or, the moving structure can also be provided on the base 220, so that the guide part and the base 220 can move together through the adaptive function of the moving structure.
[0046] In this way, after the control bottle at the testing station contacts the guide, the lifting module 110 controls the control bottle 103 at the testing station to push the guide, and under the adaptive action of the moving structure, the rotating control bottle 103 at the testing station maintains contact with the guide, and moves up and / or down past the testing position of the detection sensor 400, so that the detection sensor 400 can detect multiple points in a spiral distribution in different radius areas of the bottom of the control bottle, thereby better ensuring the accuracy of the testing results.
[0047] Compared to the first possible implementation method, the design of the moving structure in this implementation method allows the guide part to be made of non-elastic structural parts or structural parts with less elasticity, thereby ensuring the structural strength of the guide part and reducing the wear of the guide part caused by the rotation of the control bottle 103. Compared with structural parts with better elasticity such as rubber belts or elastic bands, the service life of the guide part is significantly extended, especially when the detection sensor 400 requires a high rotation speed of the control bottle 103 during the detection process.
[0048] Specifically, such as Figures 2 to 5 As shown, the guide section can be a transmission belt 210. The base 220 is provided with a driving pulley 230 and at least one driven pulley 240. The transmission belt 210 is sleeved on the driving pulley 230 and the driven pulley 240. The driving pulley 230 is provided with a drive motor 231. The drive motor 231 drives the transmission belt 210 to run cyclically through the driving pulley 230. After the transmission belt 210 contacts and engages with the control bottle 103 at the testing station, it drives the control bottle 103 at the testing station to rotate. The direction of the running section of the transmission belt 210 that contacts and engages with the control bottle 103 forms an acute angle with the rotation axis of the control bottle 103. See [reference needed]. Figure 3 and Figure 4 As shown.
[0049] Meanwhile, the driven wheel 240 is connected to the base 220 via a movable structure; the support base 100 is equipped with a lifting module 110. During the process of the lifting module 110 controlling the rise of the control bottle 103 at the inspection station to push the transmission belt 210, the driven wheel moves due to the adaptive action of the movable structure, thus... Figure 6The transmission belt 210 shown can deform accordingly, so that the rotating control bottle 103 at the detection station remains in contact with the transmission belt 210 and moves upward past the detection position of the detection sensor 400.
[0050] The moving structure can be designed as a hydraulic rod, electric rod, or rack and pinion type, which requires a power source for control; or, the moving structure can be designed as an elastic telescopic structure 250, such as a spring or sheet. The elastic telescopic structure 250 is the preferred design method, which has better adaptability than the moving structure of hydraulic rod, electric rod, or rack and pinion type, and does not require a power source.
[0051] Typically, such as Figure 5 As shown, the base 220 is provided with a fixed seat 221 and a movable seat 222. The two ends of the elastic telescopic structure 250 are respectively provided on the fixed seat 221 and the movable seat 222. The driven wheel 240 is rotatably mounted on the movable seat 222. During the process of the control bottle 103 pushing the transmission belt 210 at the inspection station, the transmission belt 210 acts on the elastic telescopic structure 250 through the driven wheel 240 and the movable seat 222, so that the elastic telescopic structure 250 produces an adaptive elastic deformation. This changes the shape of the transmission belt 210 so that the control bottle 103 maintains contact with the transmission belt 210 and moves upward, while also ensuring the normal operation of the transmission belt 210 so that it drives the control bottle 103 to rotate.
[0052] Preferably, such as Figure 2 and Figure 5 As shown, there can be two driven wheels 240, so that the transmission belt 210 sleeved on the driving wheel 230 and the two driven wheels 240 has a triangular structure. The two driven wheels 240 are respectively set on the base 220 through the oblique elastic telescopic structure 250. In this way, when the tube bottle 103 pushes the transmission belt 210, the two driven wheels 240 located at the bottom corner are more likely to be subjected to force and generate elastic deformation at the same time, and ensure the contact and cooperation effect between the bottom running section of the transmission belt 210 and the tube bottle 103.
[0053] Of course, the two driven wheels 240 mentioned above can also be respectively set on the base 220 through the transverse elastic telescopic structure 250; and, in order to improve the reliability of the movement of the movable seat 222, the base 220 and the movable seat 222 can also be provided with mutually cooperating guide structures, so that the movement of the movable seat 222 can be guided by the guide structure; for example, the base 220 is provided with a guide rail along the movement direction of the movable seat 222, and the movable seat 222 is provided with a slide groove that matches the guide rail and is held on the guide rail through the slide groove.
[0054] It is easy to understand that the guide part in the second possible implementation above can also be a pressure roller. The pressure roller is rotatably mounted on the base 220. The pressure roller is used to contact and cooperate with the control bottle 103 of the inspection station, and the rotation axis of the pressure roller is set at an acute angle to the rotation axis of the control bottle 103 of the inspection station.
[0055] The pressure roller is connected to the base 220 via the aforementioned movable structure; or, the pressure roller is directly rotatably connected to the base 220, which is provided with the aforementioned movable structure. The lifting module 110 is located on the support base 100. Thus, during the process where the lifting module 110 controls the rise of the tube bottle 103 at the detection station to push the pressure roller through the support base 100, the movable structure enables the pressure roller to move upward, thereby allowing the tube bottle 103 to maintain contact with the pressure roller and move upward past the detection position of the detection sensor 400.
[0056] It is easy to understand that the moving structure can refer to the moving structure design described above, and will not be described in detail here. Meanwhile, the pressure roller is equipped with a drive mechanism such as a drive motor. After the pressure roller contacts the controlled bottle 103 at the inspection station, the drive mechanism drives the controlled bottle 103 to rotate. The pressure roller can be directly connected to the drive mechanism such as the drive motor, or it can cooperate with a drive wheel located next to the pressure roller. The drive wheel is connected to a drive mechanism such as a drive motor, and the rotation of the drive wheel drives the pressure roller to rotate, which in turn drives the controlled bottle 103 at the inspection station to rotate. Alternatively, as an alternative, a drive mechanism such as a drive motor can be provided on the first support part 101 or the second support part 102, so that the first support part 101 or the second support part 102 rotates under the drive mechanism to drive the controlled bottle 103 at the inspection station to rotate.
[0057] In the device for detecting controlled bottles disclosed in this embodiment, in order to achieve automatic feeding of the controlled bottles to be detected, it may further include a controlled bottle transfer mechanism; specifically as follows: Figure 1 As shown, the controlled bottle transfer mechanism may include a first conveyor line 510 and a second conveyor line 520 arranged in parallel and spaced apart, and the first conveyor line 510 and the second conveyor line 520 are provided with corresponding bottle holders, so that the bottle mouth end and the bottle bottom end of the controlled bottle 103 are respectively placed on the two bottle holders corresponding to the first conveyor line 510 and the second conveyor line 520.
[0058] The support base 100 is located between the first conveyor line 510 and the second conveyor line 520, and the initial position of the support base 100 is below the feeding position of the first conveyor line 510 and the second conveyor line 520; the support base 100 is provided with a lifting module 110; the auxiliary mechanism 200 is provided with a moving structure.
[0059] During operation, the first conveyor line 510 and the second conveyor line 520, running in the same direction, transport the tubular bottle 103 placed on the bottle holder to the position corresponding to the support base 100. Then, the lifting module 110 controls the support base 100 to rise, so that the tubular bottle 103 at the detection station contacts and engages with the guide part. The tubular bottle 103 moves to the limiting part 300. At this time, the detection sensor 400 begins to detect the bottom of the rotating tubular bottle at the detection station. The lifting module 110 continues to control the support base 100 to rise. Through the moving structure, the rotating tubular bottle 103 at the detection station is kept in contact with the guide part and rises past the detection position of the detection sensor 400, so that the detection sensor 400 can detect multiple points of different radii distributed spirally on the bottom of the tubular bottle.
[0060] Next, the lifting module 110 controls the support base 100 to descend, causing the control bottle 103 at the inspection station to separate from the guide part and continue to return to the initial position. At this time, the inspected control bottle 103 is placed back on the two bottle holders corresponding to the first conveyor line 510 and the second conveyor line 520 so that the inspected control bottle 103 can be removed.
[0061] It is easy to understand that, as another design structure, the aforementioned lifting module 110 can also be set in the auxiliary mechanism 200, specifically, the base 220 of the auxiliary structure 200 is provided with the lifting module 110; correspondingly, the moving structure is set in the support base 100.
[0062] In this way, after the guide part comes into contact with the control bottle 103 at the detection station, the lifting module 110 controls the guide part to push the control bottle 103 at the detection station downward through the base 220, and the support seat 100 is lowered by the action of the moving structure, so that the control bottle 103 at the detection station remains in contact with the guide part and descends to the detection position of the detection sensor 400.
[0063] Meanwhile, the support base 100 is located between the first conveyor line 510 and the second conveyor line 520, and the initial position of the support base 100 is above the first conveyor line 510 and the second conveyor line 520. During operation, the control bottle 103 to be tested is first placed on the support base 100, and then the auxiliary mechanism 200 is lowered by the lifting module 110 so that the guide part contacts and cooperates with the control bottle 103 at the testing station. The control bottle 103 moves to the limiting part. At this time, the detection sensor 400 begins to detect the bottom of the control bottle rotating at the testing station. The lifting module 110 continues to control the auxiliary mechanism 200 to descend. Through the action of the moving structure, the control bottle 103 rotating at the testing station descends past the detection position of the detection sensor 400, so that the detection sensor 400 can detect multiple points of different radius areas of the bottom of the control bottle in a spiral distribution.
