Description

Technical Field

[0001] This utility model relates to the field of automated packaging equipment technology, and specifically to an automatic cap-laying device. Background Technology

[0002] In the large-scale production of chemical products such as inks, coatings, and resins, finished products are typically loaded into barrels and connected to various production stages via automated conveyor lines. This automates a series of processes, from manual barrel loading, automatic barrel sorting, automatic addition of colorant, and automatic filling, to automatic capping, automatic capping, and automatic printing and labeling. Robots are used to automatically grab barrels and place them into a mixing machine, automatically mix them, and automatically grab and stack the barrels, with manual transfer of pallets at the end. Among these, the automatic capping machine is one of the key pieces of equipment in the production line, and its operational stability directly affects the sealing performance and production efficiency of the products.

[0003] Currently, automatic lid-dispensing machines typically consist of a lid storage mechanism and a lid dispensing mechanism. The lid storage mechanism stores and orderly releases lids, while the lid dispensing mechanism is responsible for accurately grasping and placing lids onto the storage bin. Existing lid storage mechanisms usually employ a combination of a lid support plate, a clamping assembly, and several lid positioning optical shafts. Specifically, the lid support plate has circular holes for the lids to pass through, and positioning optical shafts are equidistantly arranged around the outer perimeter of the holes to form a lid storage space. The clamping assembly is located outside the circular holes and at the gaps between the lid positioning optical shafts to control the lid's descent. However, this lid storage mechanism has revealed numerous problems in actual operation. The lid's position within the circular holes lacks precise constraint, causing deviations in the grasping mechanism (such as a suction cup or robotic arm) during gripping, affecting the accuracy of subsequent lid dispensing actions, and even causing lids to be crooked or poorly sealed, severely impacting the accuracy of subsequent lid dispensing actions. These problems lead to unstable equipment operation, requiring frequent manual intervention, significantly reducing production efficiency and interfering with product quality stability. Utility Model Content

[0004] In response to the aforementioned problems of inaccurate lid positioning, jamming during descent, and unstable equipment operation, the applicant has designed an automatic lid-releasing device.

[0005] This application provides an automatic lid-dispensing device, which adopts the following technical solution:

[0006] An automatic lid-dispensing device includes a frame, a lid storage mechanism, and a lid-dispensing mechanism. A conveyor line runs through the frame. A bucket-holding assembly is mounted on the frame. The lid storage mechanism is located above the bucket-holding assembly and is fixedly mounted on the frame. The lid-dispensing mechanism is located between the lid storage mechanism and the bucket-holding assembly and is fixedly mounted on the frame. The lid storage mechanism includes a lid support plate and a guide conical ring. A circular hole for the lid to pass through is provided on the lid support plate. The guide conical ring is located on the lid support plate and is fixedly mounted on the edge of the circular hole.

[0007] By adopting the above technical solution, the guide cone ring has a funnel-shaped structure that is wider at the top and narrower at the bottom. Its large-diameter end is flush with and tightly fitted to the upper surface of the lid support plate, while its small-diameter end extends towards the conveyor line, with its inner diameter slightly larger than the outer diameter of the lid. When the lid falls, the guide cone ring provides precise guidance, ensuring the lid falls centered along the axis. This effectively prevents the lid from shifting or jamming during descent, greatly improving the accuracy and smoothness of the lid's fall. This provides strong support for the subsequent lid-laying mechanism to accurately grasp the lid, thereby enhancing the overall stability of the equipment.

[0008] Preferably, the lid storage mechanism further includes a clamping assembly and a lid positioning optical axis. The lid positioning optical axis is located on the side of the lid support plate away from the guide cone ring. At least four lid positioning optical axes are provided. The lid positioning optical axes are equidistantly arranged on the outer periphery of the circular hole to form a lid storage structure. The clamping assembly is located on the side of the lid support plate away from the guide cone ring and is used to control the falling of the lid.

[0009] By adopting the above technical solution, at least four equidistantly spaced lid positioning optical axes form a stable lid storage structure on the outer periphery of the circular hole. Multiple lids can be stacked longitudinally within this structure, achieving orderly storage of the lids. The clamping assembly enables precise control of the lid's descent. During equipment operation, when the lid is not needed to fall, the clamping assembly firmly holds it in place to prevent accidental drop; when the lid needs to be released, the clamping assembly accurately releases according to a pre-set program, allowing the lid to fall smoothly, ensuring that the lid-releasing action proceeds in an orderly manner according to the production rhythm.

[0010] Preferably, the clamping assembly includes at least two clamping cylinders and a supporting cylinder, which are respectively disposed opposite to each other at the gap of the positioning optical axis of the bucket lid and located outside the circular hole.

[0011] By adopting the above technical solution, the lid-clamping cylinder and the lid-supporting cylinder work together to form a highly efficient lid control mechanism. The two opposing lid-clamping cylinders can clamp the lid from both sides, providing a stable clamping force to ensure the lid does not wobble during storage. The lid-supporting cylinder supports the lid from below, preventing it from falling. When the equipment needs to release the lid, the lid-supporting cylinder retracts first, releasing its support, and then the lid-clamping cylinders loosen appropriately, allowing the bottom lid to fall smoothly. This precise coordinated control greatly improves the accuracy and reliability of the lid's descent.

[0012] Preferably, the output end of the bucket lid clamping cylinder is provided with an elastic clamping block, and the output end of the bucket lid supporting cylinder is provided with a lid supporting block.

[0013] By adopting the above technical solution, the elastic clamping block makes the lid-clamping cylinder more flexible and reliable when clamping the lid. The elastic clamping block can adaptively adjust to a certain extent according to the shape and size of the lid, avoiding damage to the lid caused by rigid clamping, while also enhancing compatibility with lids of different specifications. The lid support block provides a stable support plane for the lid. Compared with ordinary support structures, the lid support block can more effectively distribute the weight of the lid, preventing the lid from tilting or shifting when supported, further improving the stability of the lid during storage and dropping.

[0014] Preferably, the bucket-holding assembly includes two bucket-holding cylinders and bucket-holding clamps. The two bucket-holding cylinders are located on both sides of the conveyor line and are symmetrically fixed on the frame. The two bucket-holding clamps are respectively installed at the output ends of the two bucket-holding cylinders.

[0015] By adopting the above technical solution, once the material bucket moves to the designated position along the conveyor line, the two bucket-holding cylinders work synchronously, driving the bucket-holding clamps to move inward simultaneously and tightly hold the material bucket. The bucket-holding clamps fit tightly against the outer wall of the material bucket, effectively preventing the material bucket from moving further and keeping the material bucket stable during the capping process. This ensures precise alignment between the cap and the material bucket during capping, avoiding problems such as capping failure or improper cap placement caused by material bucket shaking, which is of great significance for improving product sealing and production efficiency.

[0016] Preferably, the cap-laying mechanism includes a supporting optical axis, a movable disk, and a lifting cylinder. The supporting optical axis is vertically fixedly mounted on the frame. A rotating cap-laying assembly is mounted on one side of the movable disk, and the side of the movable disk opposite to the rotating cap-laying assembly is slidably mounted on the supporting optical axis. The lifting cylinder is vertically mounted on the frame and arranged parallel to the supporting optical axis. The output end of the lifting cylinder is fixedly connected to the side of the movable disk opposite to the rotating cap-laying assembly.

[0017] By adopting the above technical solution, the extension and retraction of the lifting cylinder enables the moving plate to move vertically up and down along the support optical axis. When it is necessary to remove the cap, the lifting cylinder extends, pushing the moving plate upward, so that the rotating cap-dispensing assembly can reach the cap-holding mechanism to grab the cap; after the cap is removed, the lifting cylinder retracts, driving the moving plate downward to place the cap onto the material bucket. The support optical axis provides a stable guide for the movement of the moving plate, ensuring that the rotating cap-dispensing assembly maintains an accurate position during its up and down movement, effectively improving the accuracy of the cap-dispensing action.

[0018] Preferably, there are two supporting optical shafts, which are vertically fixed on the frame. The lifting cylinder is located between the two supporting optical shafts, and the movable disk is provided with a slider that slides with the two supporting optical shafts.

[0019] By adopting the above technical solution, two supporting optical axes provide more stable support and more precise guidance for the moving disk compared to a single supporting optical axis. The moving disk, through a slider sliding into the two supporting optical axes, further enhances its smoothness in vertical movement, greatly reducing swaying and offset during movement. This structural design makes the rotating lid-dispensing assembly more precise and reliable in grasping and placing lids, significantly improving the success rate of lid placement and the overall operational stability of the equipment.

[0020] Preferably, the rotating cap placement assembly includes a pressing cylinder, a rotating cylinder, and a cap-removing suction cup. The pressing cylinder is fixedly mounted on the movable disk, the rotating cylinder is mounted on the movable end of the pressing cylinder, and the cap-removing suction cup is mounted on the movable end of the rotating cylinder.

[0021] By adopting the above technical solution, during the cap placement process, the moving plate rises to the cap storage mechanism position, and the rotary cylinder drives the cap-retrieving suction cup upwards, using the suction force of the suction cup to pick up the cap. After picking up the cap, the moving plate descends to its original position. At this time, the rotary cylinder flips, causing the cap-retrieving suction cup to grip the cap downwards. Then, the pressing cylinder moves down, pushing the cap-retrieving suction cup to accurately place the cap onto the material bucket held by the lower bucket-holding assembly. This multi-cylinder collaborative design achieves complex and precise cap picking, rotation, and placement actions, greatly improving the automation and accuracy of cap placement and effectively increasing production efficiency.

[0022] Preferably, the conveyor line is equipped with two bucket position detectors for detecting the buckets. The two bucket position detectors are fixedly installed on both sides of the conveyor and correspond to the positions of the two bucket-holding cylinders.

[0023] By adopting the above technical solution, the bucket position detector can monitor the bucket's running position on the conveyor line in real time and promptly feed the detection signal back to the equipment controller. When the bucket reaches the designated position, the controller immediately issues a command based on the received signal. At this time, the conveyor line stops moving, and the bucket-holding cylinders on both sides of the frame operate to hold the bucket tightly. This design achieves precise control of the bucket's position, ensuring that the bucket-holding assembly and the cap-releasing mechanism can operate on the bucket at the correct time, further improving the accuracy of cap release and the reliability of equipment operation, reducing manual intervention, and significantly improving overall production efficiency.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The guide cone ring has a funnel-shaped structure that is wider at the top and narrower at the bottom. Its large-diameter end is flush with and tightly fitted to the upper surface of the lid support plate, while the small-diameter end extends towards the conveyor line, and the inner diameter of the small-diameter end is slightly larger than the outer diameter of the lid. When the lid falls, the guide cone ring can play a precise guiding role, so that the lid falls in the center along the axis, effectively avoiding the lid from shifting or getting stuck during the fall. This greatly improves the accuracy and smoothness of the lid's fall, providing a strong guarantee for the subsequent lid-laying mechanism to accurately grab the lid, thereby improving the stability of the entire equipment operation.

[0026] 2. At least four equidistant lid positioning optical axes form a stable lid storage structure on the outer periphery of the circular hole. Multiple lids can be stacked longitudinally in sequence within this structure, achieving orderly storage of lids. The clamping component enables precise control of lid descent. During equipment operation, when lid descent is not required, the clamping component can firmly hold the lid to prevent accidental drop. When lid release is required, the clamping component can accurately release according to the set program, allowing the lid to fall smoothly, ensuring that the lid release action proceeds in an orderly manner according to the production rhythm.

[0027] 3. The extension and retraction of the lifting cylinder drives the moving plate to move vertically up and down along the support optical axis. When it is necessary to remove the cap, the lifting cylinder extends, pushing the moving plate upward so that the rotating cap-dispensing assembly can reach the cap-holding mechanism to grab the cap; after removing the cap, the lifting cylinder retracts, driving the moving plate downward to place the cap onto the material bucket. The support optical axis provides stable guidance for the movement of the moving plate, ensuring that the rotating cap-dispensing assembly maintains an accurate position during its up and down movement, effectively improving the accuracy of the cap-dispensing action.

[0033] This application discloses an automatic lid-releasing device.

[0034] An automatic lid-dispensing device, as described in the following description Figure 1 and Figure 2 The system includes a frame 1, a lid storage mechanism 2, and a lid placement mechanism 3. A conveyor line runs through the frame 1. The lid storage mechanism 2 is located above the conveyor line and is used to store lids. The lid storage mechanism 2 is fixedly installed on the frame 1. A bucket holding assembly 4 is provided on the frame 1. The conveyor line transports the buckets to a designated position and fixes the buckets through the bucket holding assembly 4. The lid placement mechanism 3 is located between the conveyor line and the lid storage mechanism 2 and is fixedly installed on the frame 1. The lid placement mechanism 3 is used to grab the lids from the lid storage mechanism 2 and place them onto the fixed buckets.

[0035] When in use, the material bucket enters the equipment from the production line. The conveyor line can drive the material bucket to move forward. After the material bucket moves to the designated position on the conveyor line, the bucket holding assembly 4 holds and positions the material bucket. The lid placement mechanism 3 can place the lid on the lid storage mechanism 2 onto the top of the material bucket and complete the lid placement action.

[0036] Specifically, the lid storage mechanism 2 includes a lid support plate 21, a clamping assembly 22, and several lid positioning optical shafts 23. The lid support plate 21 is located above the conveyor line and is fixedly installed on the frame 1. The lid support plate 21 has a circular hole 5 for the lid to pass through. The clamping assembly 22 is fixedly installed on the side of the lid support plate 21 away from the conveyor line and is used to clamp and fix the lid. Several lid positioning optical shafts 23 are fixedly installed on the side of the lid support plate 21 away from the conveyor line and are equidistantly arranged along the outer periphery of the circular hole 5.

[0037] Four bucket lid positioning optical axes 23 are provided, and the four bucket lid positioning optical axes 23 are equidistantly arranged circumferentially on the outside of the circular hole 5, thereby forming a bucket lid storage structure. Multiple bucket lids are stacked longitudinally in the above-mentioned bucket lid storage structure. The clamping assembly 22 includes two bucket lid clamping cylinders 221 and two bucket lid supporting cylinders 222. Two bucket lid clamping cylinders 221 and two bucket lid supporting cylinders 222 are respectively arranged opposite to each other at the gap of the bucket lid positioning optical axes 23 and located on the outside of the circular hole 5, forming two types of structures: lid supporting and lid clamping, which can respectively play the role of supporting and clamping the bucket lid.

[0038] Furthermore, both bucket lid clamping cylinders 221 are equipped with elastic clamping blocks at their output ends, and both bucket lid supporting cylinders 222 are equipped with lid supporting blocks at their extension and retraction ends. The elastic clamping blocks on the extension and retraction ends of the bucket lid clamping cylinders 221 allow them to clamp the bucket lids within the lid storage structure, while the lid supporting cylinders 222 prevent the bucket lids within the lid storage structure from falling. The combined action of the bucket lid clamping cylinders 221 and the lid supporting cylinders 222 achieves the control action of the bucket lid falling.

[0039] Furthermore, the lid storage mechanism 2 also includes a guide conical ring 24. The guide conical ring 24 is located on the side of the lid support plate 21 away from the lid positioning optical axis 23, and the guide conical ring 24 is fixedly installed on the edge of the circular hole 5. The guide conical ring 24 has a funnel-shaped structure that is wider at the top and narrower at the bottom. The large-diameter end of the guide conical ring 24 is flush with and tightly fitted to the upper surface of the lid support plate 21, and the small-diameter end extends towards the conveyor line. The inner diameter of the small-diameter end is slightly larger than the outer diameter of the lid, so as to accurately guide the lid to fall in the center along the axial direction and avoid the lid from shifting or getting stuck during the falling process.

[0040] Specifically, the bucket-holding assembly 4 includes two bucket-holding cylinders 41 and bucket-holding clamps 42. The two bucket-holding cylinders 41 are located on both sides of the conveyor line and are symmetrically fixed on the frame 1, with their output ends facing each other. The two bucket-holding clamps 42 are respectively installed on the output ends of the two bucket-holding cylinders 41. When the bucket reaches the designated position on the conveyor line, the bucket-holding cylinders 41 operate to cause the bucket-holding clamps 42 on both sides to move inward simultaneously and hold the bucket tightly, preventing the bucket from moving further. The bucket-holding clamps 42 are provided with grooves that fit the outer wall of the bucket. By setting the grooves, the bucket can be held tighter and slippage can be prevented.

[0041] Reference Figure 3 and Figure 4Specifically, the cap-laying mechanism 3 includes a supporting optical shaft 31, a movable disk 32, and a lifting cylinder 33. The supporting optical shaft 31 is located between the conveyor line and the cap-storage mechanism 2, and is vertically fixedly installed on one side of the frame 1. One side of the movable disk 32 is fixedly connected to the supporting optical shaft 31 and is slidably mounted on the supporting optical shaft 31. A rotating cap-laying assembly 6 is provided on the side of the movable disk 32 away from the supporting optical shaft 31. The lifting cylinder 33 is located on the side of the movable disk 32 away from the rotating cap-laying assembly 6, and is fixedly installed on the frame. The movable end of the lifting cylinder 33 is fixedly connected to the side of the movable disk 32 away from the rotating cap-laying assembly 6. By extending and retracting the lifting cylinder 33, the movable disk 32 moves vertically up and down along the supporting optical shaft 31, thereby driving the rotating cap-laying assembly 6 to move up and down.

[0042] There are two supporting optical shafts 31, which are arranged parallel to each other on one side of the frame 1. The movable disk 32 is provided with a slider 7 that slides with the two supporting optical shafts 31 on the side opposite to the rotating lid-laying assembly 6. When the lid-laying action is required, the lifting cylinder 33 drives the movable disk 32 to move upward along the supporting optical shafts 31, so that the rotating lid-laying assembly 6 can take out the bucket lid from the upper lid storage mechanism 2 and place it on the material bucket of the lower conveyor line, thereby achieving the lid-laying effect of the equipment.

[0043] Furthermore, the rotating lid-laying assembly 6 includes a pressing cylinder 61, a rotating cylinder 62, and a lid-removing suction cup 63. The pressing cylinder 61 is located on the side of the moving disk 32 away from the slider 7. When the lifting cylinder 33 moves the moving disk 32, the moving disk 32 can move the pressing cylinder 61. The rotating cylinder 62 is located on the movable end of the pressing cylinder 61, and the lid-removing suction cup 63 is located on the movable end of the rotating cylinder 62. When the rotating lid-laying assembly 6 is working, the moving disk 32 moves upward, the rotating cylinder 62 drives the lid-removing suction cup 63 upward, and removes the lid from the lid storage mechanism 2. After the removal action is completed, the moving disk 32 resets, the rotating cylinder 62 flips and drives the lid-removing suction cup 63 to grab the lid downward, and the pressing cylinder 61 moves downward, so that the lid-removing suction cup 63 drives the lid down onto the lid held by the lower bucket-holding assembly 4, thereby achieving the lid-laying effect of the equipment.

[0044] Furthermore, a bucket position detector 8 is installed on the conveyor line; there are two bucket position detectors 8, which are fixedly installed on both sides of the conveyor line and correspond to the positions of the two bucket-holding cylinders 41; the bucket position detectors 8 are electrically connected to the equipment controller and can detect the running position of the bucket on the equipment and feed it back to the controller; when the bucket is conveyed to the designated position by the conveyor line, the bucket position detector 8 detects the bucket, at which time the conveyor line stops moving, and the bucket-holding cylinders 41 located on both sides of the conveyor line on the frame 1 clamp the bucket and complete the bucket fixation.

[0045] The implementation principle of the application embodiment is as follows: Automatic lid-laying equipment for material drums is of great significance in the large-scale production of chemical products such as inks, coatings, and resins. This equipment includes a frame 1, a lid storage mechanism 2, a lid-laying mechanism 3, and a drum-holding assembly 4. During operation, the material drums are transported by a conveyor line, and the drum position detector 8 monitors their position. Upon reaching the designated position, the drum-holding assembly 4 clamps and secures the drum. Within the lid storage mechanism 2, the lids are stored orderly in the structure formed by the lid positioning optical axis 23. The clamping assembly 22 precisely controls the descent of the lids, and the guide conical ring 24 guides the lids to accurately fall into the lid-retrieving area. The lifting cylinder 33 of the lid-laying mechanism 3 drives the moving plate 32 and the rotating lid-laying assembly 6 to move up and down. The rotating lid-laying assembly 6, through the coordinated action of multiple cylinders, completes the lid-retrieving, rotating, and lid-laying actions, accurately placing the lids onto the material drums. The various components of the equipment work closely together in a cyclical manner, effectively solving the problems of inaccurate lid positioning, sluggish descent, and unstable equipment operation in traditional lid-laying methods, greatly improving production efficiency and product sealing.

[0046] 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.
