Description

Technical Field

[0001] This application relates to the technical field of bottle cap conveying, and in particular to a bottle cap feeding and conveying mechanism. Background Technology

[0002] In the packaging manufacturing industry, bottle cap feeding is a crucial step. With the continuous improvement of industrial automation, the efficiency and accuracy of bottle cap feeding are becoming increasingly critical for the smooth operation of the entire production process. An efficient bottle cap feeding system can significantly increase production line capacity, reduce labor costs, and ensure product quality stability, which is of great significance for enterprises to enhance their market competitiveness.

[0003] Current bottle cap feeding methods primarily rely on the cooperation of conveyor belts and grippers. Typically, bottle caps are conveyed to the gripper via the conveyor belt, where they are then grasped. In practical applications, to achieve bottle cap feeding, the common practice is to use the continuous operation of the conveyor belt to sequentially transport the bottle caps to designated positions. Some systems are equipped with positioning devices to assist the gripper in more precise grasping of bottle caps, while others adjust the conveyor belt speed to adapt to different feeding rhythms.

[0004] However, traditional bottle cap feeding methods have significant drawbacks. Because some bottle caps are arranged very closely together on the conveyor belt, with little spacing between them, the gripper struggles to accurately and effectively pick them up. This problem severely impacts the efficiency of bottle cap feeding, thus hindering the speed of the entire packaging production process, and therefore requires further improvement. Utility Model Content

[0005] To address the above problems, this application provides a bottle cap feeding and conveying mechanism.

[0006] This application provides a bottle cap feeding and conveying mechanism, which adopts the following technical solution:

[0007] A bottle cap feeding and conveying mechanism includes a frame, a conveyor belt wound around the frame, a drive assembly for driving the conveyor belt to move, and a lifting assembly disposed near one end of the frame near a gripper to drive the bottle caps to rise and fall. The lifting assembly includes a lifting platform disposed on the frame, a stop bar disposed on the top of the lifting platform, and a drive component for driving the lifting platform to rise and fall. The lifting platform is for placing a single bottle cap.

[0008] By adopting the above technical solution, during the bottle cap loading process, the conveyor belt, driven by the drive component, transports the bottle caps to a position close to the gripper. The lifting component located near the gripper end of the frame effectively solves the bottle cap gripping problem. When a single bottle cap is conveyed to the lifting platform, the stop bar reduces the possibility of the bottle cap slipping or shifting, ensuring the bottle cap remains stably positioned on the platform. Subsequently, the drive component raises the lifting platform, lifting the bottle cap and creating distance between it and adjacent bottle caps. This facilitates precise gripping by the gripper, reducing situations where the gripper struggles to grasp caps due to insufficient spacing, and significantly improving the efficiency of bottle cap loading.

[0009] Preferably, the baffle is U-shaped, with its opening facing the conveyor belt, and the baffle is detachably connected to the lifting platform.

[0010] By adopting the above technical solution, the U-shaped baffle opening faces the conveyor belt, which facilitates the entry of individual bottle caps into the lifting platform. The detachable connection makes it easy to replace or maintain the baffle, so that different sizes of baffles can be replaced according to different sizes of bottle caps, so that the placed bottle caps can be relatively centered, reducing the difficulty for the gripper to grab the bottle caps.

[0011] Preferably, the conveyor belt is inclined downwards towards the position close to the gripper, and when the driving component does not drive the lifting platform to rise, the platform height is less than the height of the upper surface of the conveyor belt.

[0012] By adopting the above technical solution, the conveyor belt is inclined downwards, which makes it easier for the bottle caps to move towards the gripper by gravity. The lifting platform is lower than the upper surface of the conveyor belt, which allows individual bottle caps to roll naturally onto the lifting platform, making it easier for the lifting platform to be raised and picked up by the gripper, thus improving work efficiency.

[0013] Preferably, it further includes two first limiting strips respectively disposed on both sides of the frame, and the frame is provided with a first adjusting member for adjusting the distance between the two first limiting strips.

[0014] By adopting the above technical solution, first limit strips are set on both sides of the frame and equipped with first adjustment components for adjusting the spacing. The spacing between the two first limit strips can be adjusted to flexibly limit the conveying range of bottle caps on the conveyor belt, ensuring that the bottle caps are accurately conveyed to the lifting platform for easy subsequent operation.

[0015] Preferably, there are two first adjusting members, which are respectively disposed on both sides of the frame. The first adjusting member includes a second adjusting screw rotatably connected to the first limiting strip and a second mounting seat through which the second adjusting screw rotatably passes. The second mounting seat is mounted on the frame.

[0016] By adopting the above technical solution, two first adjusting components are provided and located on both sides of the frame. Each component includes a second adjusting screw rotatably connected to the first limiting strip and a second mounting seat for rotatable insertion and installation on the frame. The spacing between the first limiting strips on both sides of the frame can be adjusted to meet the conveying requirements of bottle caps of different specifications.

[0017] Preferably, the outer surface of the first limiting strip away from the bottle cap is provided with a T-shaped groove, the groove being provided along the entire length of the first limiting strip, and the end of the second adjusting screw is rotatably connected to a first slider, the first slider being adapted to the groove, and the slider being slidably connected to the groove.

[0018] By adopting the above technical solution, the second adjusting screw is rotated through the first slider and slidably connected to the groove, so that the second adjusting screw or the first limiting strip can be disassembled and replaced.

[0019] Preferably, the first adjusting member further includes a first adjusting screw threaded through the second mounting base and a first mounting base rotatably connected to the first adjusting screw. The first adjusting screw is vertically arranged, the first adjusting screw is threaded through the first mounting base, and the first mounting base is mounted on the frame.

[0020] By adopting the above technical solution, during the bottle cap feeding and conveying process, the first adjusting screw in the first adjusting component is threaded through the second mounting seat. When the first adjusting screw is rotated, based on the principle of thread transmission, the second mounting seat and the first limiting strip can move along the height direction, thereby adjusting the height of the two first limiting strips to meet the conveying needs of bottle caps of different height specifications.

[0021] Preferably, the frame is provided with a second limiting strip above the bottle cap, the second limiting strip is rotatably connected to a third adjusting screw, the first adjusting screw passes through a mounting plate, the third adjusting screw passes through the mounting plate, and the third adjusting screw is threadedly connected to a second bolt.

[0022] By adopting the above technical solution, a second limiting strip is set above the bottle cap on the frame. The second limiting strip is rotatably connected to a third adjusting screw. The first adjusting screw passes through the mounting plate and the second adjusting screw passes through the mounting plate. This can provide more comprehensive limiting for the bottle cap, improve the stability of the bottle cap during the conveying process, and at the same time, it can work with the first adjusting component to flexibly adjust the limiting structure according to different bottle cap sizes.

[0023] In summary, this application has the following beneficial effects:

[0024] 1. By installing a lifting component that can lift bottle caps at one end of the conveyor belt, individual bottle caps can be lifted, making it easier for the gripper to pick them up, reducing the problem of difficulty in picking up bottle caps due to small spacing, and improving work efficiency.

[0025] 2. A stop bar is installed on the top of the lifting platform to limit the bottle cap and reduce its slippage during lifting;

[0026] 3. The conveyor belt is inclined downwards towards the gripper, and when not raised, the height of the lifting platform is less than the height of the upper surface of the conveyor belt, which facilitates the transfer of bottle caps from the conveyor belt to the lifting platform.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail below.

[0033] This application discloses a bottle cap feeding and conveying mechanism.

[0034] Example 1:

[0035] A bottle cap feeding and conveying mechanism, as described in the following figure Figure 1 The system includes a frame 1, a conveyor belt 2 wound around the frame 1, a drive assembly 3 for driving the conveyor belt 2, a lifting assembly 6 located at one end of the frame 1 near the gripper 4 to lift the bottle cap 5, and two first limiting strips 7 respectively located on both sides of the frame 1. It should be noted that, to improve the conveying effect of the bottle cap 5, the conveyor belt 2 can be inclined downwards towards the gripper 4. Specifically, the drive assembly 3 includes two rotating shafts respectively rotatably connected to both ends of the frame 1 and a drive motor for driving one of the rotating shafts.

[0036] The lifting assembly 6 is located at one end of the frame 1 near the gripper 4, and can lift a single bottle cap 5 to facilitate gripping by the gripper 4. Specifically, the lifting assembly 6 includes a lifting platform 61 located on the frame 1, a stop bar 62 located on the top of the lifting platform 61, and a drive component 63 that drives the lifting platform 61 to lift.

[0037] The baffle 62 is U-shaped, with its opening facing the conveyor belt 2. This structure facilitates the entry of the bottle cap 5 from the conveyor belt 2 onto the lifting platform 61. The baffle 62 can be made of materials such as plastic or metal. A plastic baffle 62 is lightweight and has a certain degree of flexibility, reducing damage to the bottle cap 5. The baffle 62 is detachably connected to the lifting platform 61, specifically via a first bolt. Figure 2 As shown, this connection method facilitates the disassembly and replacement of the baffle 62. The driving component 63 can be a cylinder or an electric actuator, etc. Taking a cylinder as an example, the cylinder body is fixed to the frame 1 by a fixing plate 11, and the piston rod is connected to the lifting platform 61. When the cylinder is ventilated, the piston rod extends or retracts, thereby driving the lifting platform 61 to descend or rise.

[0038] It should be noted that when the drive unit 63 does not drive the lifting platform 61 to rise, the platform height of the lifting platform 61 is less than the height of the upper surface of the conveyor belt 2, so that the bottle cap 5 can smoothly roll from the conveyor belt 2 onto the lifting platform 61.

[0039] Specifically, the first limiting strip 7 is parallel to the length direction of the frame 1. The first limiting strip 7 can be made of metal or plastic and its function is to limit the bottle caps 5 on the conveyor belt 2, preventing them from falling off either side of the conveyor belt 2. A T-shaped groove 71 is provided on the outer surface of the first limiting strip 7 away from the bottle cap 5, and the groove 71 extends along the entire length of the first limiting strip 7.

[0040] Reference Figure 1 , Figure 3The frame 1 is equipped with a first adjusting component for adjusting the distance between the two first limiting bars 7. Two first adjusting components are provided, one on each side of the frame 1. Each first adjusting component includes a first mounting base 81, a first adjusting screw 82, a second mounting base 83, and a second adjusting screw 84. The first mounting base 81 is threaded with a second bolt 811, which is threaded to the side wall of the frame 1 to mount the first mounting base 81 onto the frame 1. The first adjusting screw 82 is vertically oriented, with its lower end rotatably connected to the first mounting base 81. The second mounting base 83 is positioned above the first mounting base 81. The first adjusting screw 82 is threaded through the second mounting base 83. The second adjusting screw 84 is horizontally oriented, perpendicular to the height of the first adjusting screw 82 and parallel to the width of the frame 1. The second adjusting screw 84 is threaded through the second mounting base 83. The end of the second adjusting screw 84 is rotatably connected to the first slider 841, which is adapted to the groove 71 and is slidably connected to the groove 71.

[0041] Furthermore, to provide a limiting effect on the bottle cap 5, in this embodiment, a second limiting strip 12 is provided above the bottle cap 5 on the frame 1. The length direction of the second limiting strip 12 is parallel to the length direction of the frame 1. For the installation of the second limiting strip 12, a third adjusting screw 13 is rotatably connected to the second limiting strip 12. Two first adjusting screws 82 pass through the mounting plate 821, and the third adjusting screw 13 passes through the mounting plate 821. Both the first adjusting screws 82 and the third adjusting screw 13 are threadedly connected to nuts 9, and the nuts 9 abut against the mounting plate 821.

[0042] It should be noted that the upper surface of the second limiting strip 12 also has a groove 71, and the second adjusting screw 84 passes through the mounting plate 821. The third adjusting screw 13 is configured similarly to the second adjusting screw 84, and is connected to the second limiting strip 12.

[0043] The implementation principle of a bottle cap feeding and conveying mechanism according to an embodiment of this application is as follows: During the bottle cap feeding process, the conveyor belt 2 can transport the bottle cap 5 under the drive of the drive component 3, bringing the bottle cap 5 close to the gripper 4. The lifting component 6, located at the end of the frame 1 near the gripper 4, effectively solves the problem of gripping the bottle cap 5. When a single bottle cap 5 is transported to the lifting platform 61, the stop bar 62 can reduce the possibility of the bottle cap 5 slipping or shifting, ensuring that the bottle cap 5 is stably placed on the lifting platform 61. Then, the drive component 63 drives the lifting platform 61 to rise, lifting the bottle cap 5 and creating distance between the bottle cap 5 and other adjacent bottle caps 5, thereby facilitating the gripper 4 to accurately grip the bottle cap 5, reducing the situation where the gripper 4 has difficulty gripping due to the small distance between the bottle caps 5, and greatly improving the working efficiency of bottle cap feeding.

[0044] Example 2:

[0045] Reference Figure 4 The difference from Embodiment 1 is that, in order to reduce the possibility of the first limiting bar 7 slipping along its length direction during vibrations transmitted through rigid contact by a motor or other driving sources, in this embodiment, the lower surface of the second limiting bar 12 is provided with a sliding member 121, and the upper surface of the frame 1 is provided with a sliding groove 14 for the sliding member 121 to slide, the length direction of the sliding groove 14 being parallel to the width direction of the frame 1.

[0046] It should be noted that, in order to limit the sliding of the first limiting strip 7 while the first adjusting screw 82 drives the second mounting base 83 and the limiting strip to rise and fall, in this embodiment, the slide groove 14 can extend to the lower surface of the frame 1, and the sliding member 121 can be a sliding rod or a sliding plate; or the sliding member 121 can be a telescopic sliding rod or a sliding plate, depending on the requirements. In this embodiment, the slide groove 14 can extend to the lower surface of the frame 1, and the sliding member 121 is a sliding rod.

[0047] A sliding member 121, specifically a sliding rod, is also provided on the second limiting bar 12. The upper end of the sliding rod slides through the mounting plate 821.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
