Technical Field

[0001] This invention relates to the field of capping device technology, and more specifically to an automatic cap tightening device for a mobile production line. Background Technology

[0002] In bottle filling production lines, automated cap tightening devices are often needed to securely install caps at the bottle opening, reducing manual installation time. Existing automatic cap tightening devices can basically meet daily usage needs, but there are still some shortcomings that need to be improved.

[0003] Patent document CN211198547U discloses an automatic bottle cap tightening device, relating to the field of automation equipment technology. It solves the technical problem of limited product variety due to the relatively simple bottle clamping device. The automatic bottle cap tightening device includes multiple support pillars, with a worktable between the pillars. A clamping structure for clamping the bottle is located on the side of the worktable away from the pillars, a tightening structure for tightening the bottle cap, and a lifting structure for adjusting the height of the tightening structure. The clamping structure includes a clamping cylinder, a mounting plate, a sliding groove, a sliding block, a clamping spring, and an elastic element. The clamping cylinder is connected to the lifting structure, and the mounting plate is connected to the output end of the clamping cylinder. The sliding groove is located on the mounting plate perpendicular to the lifting direction of the tightening structure. The sliding block is slidably disposed within the sliding groove. One end of the clamping spring is connected to the sliding block, and the other end is connected to the bottom of the sliding groove. The elastic element is installed on the end of the sliding block away from the clamping cylinder.

[0004] In the prior art as described in the above patent, the bottle cap tightening process is automatic, but matching the bottle cap with the bottle body one by one still requires additional manual operation. Therefore, there is an urgent need for an automatic bottle cap tightening device on a mobile production line to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic bottle cap tightening device for mobile production lines to overcome the aforementioned shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An automatic bottle cap tightening device for a production line is mounted on a support, with a conveyor belt for conveying bottles positioned below it. The device includes: a suspension platform, which is vertically mounted on the support; a suspension seat, which is rotatably mounted below the suspension platform and driven by a rotary motor mounted on the suspension platform, with a clamping component at its lower end for clamping bottle caps; a docking platform, which is horizontally openable and closable between the conveyor belt and the suspension seat; a cap-replenishing component, mounted on the support, for individually conveying bottle caps to the docking platform; and a clamping component, located below the docking platform, for clamping and positioning the bottles conveyed to the lower side of the docking platform.

[0008] Preferably, the snap-fit ​​assembly includes multiple snap-fit ​​sleeves movably disposed at the lower end of the suspension seat and a top column that is elastically raised and lowered. The top column is linked to the snap-fit ​​sleeves through a linkage component disposed inside the suspension seat. When the top column rises relative to the suspension seat, the multiple snap-fit ​​sleeves move closer to each other.

[0009] Preferably, a top plate is provided at the lower end of the top column, and a first elastic element is connected between the upper side of the top plate and the suspension seat.

[0010] Preferably, the linkage component includes a linkage block that is movably disposed within the suspension seat and rises and falls synchronously with the top column. The linkage block is provided with an inclined sliding groove, and a connector is provided on the sleeve. One end of the connector is movably inserted into the suspension seat and is provided with a sliding pin that matches the inclined sliding groove.

[0011] Preferably, a protruding ring is provided on the top column, a displacement groove matching the protruding ring is provided in the linkage block, and a second elastic element is provided between the upper side of the protruding ring and the top surface of the displacement groove.

[0012] Preferably, the suspension seat is provided with a limiting component for limiting the movement of the top column. When the top column rises to its highest position relative to the suspension seat, it is limited by the limiting component. A telescopic unit is provided between the suspension seat and the rotary motor. When the telescopic unit is retracted to its shortest length, it triggers the limiting component to cancel the limiting.

[0013] Preferably, the limiting component includes a lever that is elastically rotatably disposed inside the suspension seat, a concave annular groove that matches the lever is provided on the outer wall of the top column, a reset rod is fixedly disposed on the outer wall of the telescopic unit, and one end of the lever extends through and out of the side wall of the suspension seat and is disposed vertically and vertically corresponding to the reset rod.

[0014] Preferably, the docking platform includes two oppositely arranged flaps, which are driven by telescopic cylinders on the support.

[0015] Preferably, the capping assembly includes a transition platform mounted on a support, the transition platform being fitted to the upper side of the docking platform, a one-way frame for stacking and loading bottle caps on the transition platform, and a push plate for individually pushing the bottommost bottle cap on the side of the transition platform away from the suspension seat, the push plate being driven by a telescopic cylinder on the transition platform.

[0016] Preferably, the clamping assembly includes two clamping blocks disposed opposite each other on the bracket, the clamping blocks being driven by a telescopic cylinder on the bracket.

[0017] In the above technical solution, the beneficial effects of the present invention are:

[0018] The automatic bottle cap tightening device on this mobile production line uses a docking platform and a cap replenishment component. The cap replenishment component transports bottle caps individually to the closed docking platform. Then, the suspension platform drives the suspension seat to descend, and the clamping component grabs and clamps the bottle cap. The docking platform then opens, and the bottle body is clamped by the clamping component and positioned directly below the suspension seat. The suspension platform continues to drive the suspension seat to descend, and at the same time, the rotary motor drives the suspension seat to rotate. This achieves automatic matching and tightening of the bottle cap and bottle body, greatly improving the efficiency of bottle cap installation.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0031] Please see Figure 1-6 This invention provides an automatic bottle cap tightening device for a production line, which is mounted on a support 1, with a conveyor belt 2 for conveying bottles positioned below it. The device includes: a suspension platform 3, which is vertically mounted on the support 1; a suspension seat 4, which is rotatably mounted below the suspension platform 3 and driven by a rotary motor 5 mounted on the suspension platform 3, with a clamping component at its lower end for clamping bottle caps; a docking platform, which is horizontally openable and closable between the conveyor belt 2 and the suspension seat 4; a cap-replacing component, mounted on the support 1, for individually conveying bottle caps to the docking platform; and a clamping component, located below the docking platform, for clamping and positioning the bottles conveyed to the lower side of the docking platform.

[0032] Specifically, the support frame 1 has a frame-like structure; the conveyor belt 2 passes through the support frame 1 in the conveying direction, and intermittently conveys the bottle to the area directly below the suspension seat 4, which corresponds exactly to the clamping center of the clamping component; the support frame 1 is equipped with guide posts, and the suspension seat 3 is equipped with guide sleeves fitted on the guide posts; a telescopic cylinder is vertically mounted on the support frame 1, with its output end pointing downwards and connected to the suspension seat 3; the rotary motor 5 can be linked with the telescopic cylinder under the control of a servo system, causing the suspension seat 4 to rotate spirally to match the spiral trajectory of the bottle cap tightening, which is existing technology and will not be elaborated further; the clamping component is used to grab the bottle cap, and after grabbing... The bottle cap moves synchronously with the suspension seat 4. The opening and closing function of the docking platform is used to form a horizontal platform between the suspension seat 4 and the conveyor belt 2 when closed, allowing the bottle cap to move to this horizontal platform first, and then be engaged with the suspension seat 4 through the snap-fit ​​component. When open, the bottle cap is directly aligned with the bottle body positioned by the clamping component below, and the up and down movement of the bottle cap is unimpeded, facilitating the tightening of the bottle cap. The cap replenishing component is used to independently transport the bottle caps to the docking platform in the closed state, and it is located directly below the suspension seat 4. The clamping component clamps and positions the bottle body on the conveyor belt 2, so that it is aligned directly below the suspension seat 4. In practical use, the clamping assembly clamps and positions the bottle conveyed on the conveyor belt 2 directly below the docking platform. The capping assembly conveys the bottommost single bottle cap to the closed docking platform. Then, the suspension platform 3 drives the suspension seat 4 to descend. The locking assembly grabs and locks the bottle cap. Then, the docking platform opens, and the bottle is directly aligned with the lower side of the suspension seat 4. The suspension platform 3 continues to drive the suspension seat 4 to descend, while the rotary motor 5 drives the suspension seat 4 to rotate, thereby tightening the bottle cap onto the bottle.

[0033] Compared with the prior art, the automatic bottle cap tightening device for a production line proposed in this embodiment of the invention sets up a docking platform and a cap replenishment component. The cap replenishment component transports the bottle caps individually to the closed docking platform. Then, the suspension platform 3 drives the suspension seat 4 to descend, and the clamping component grabs and clamps the bottle cap. Then the docking platform opens again, and the bottle body is clamped by the clamping component and positioned directly below the suspension seat 4. The suspension platform 3 continues to drive the suspension seat 4 to descend, and at the same time, the rotary motor 5 drives the suspension seat 4 to rotate. In this way, the bottle cap can be tightened onto the bottle body. The above realizes the automatic matching and automatic tightening of the bottle cap and the bottle body, which greatly improves the efficiency of bottle cap installation.

[0034] As a preferred technical solution in this embodiment, the snap-fit ​​assembly includes multiple snap-fit ​​sleeves 6 movably disposed at the lower end of the suspension seat 4 and a top column 7 elastically lifted and lowered. The top column 7 is linked with the snap-fit ​​sleeves 6 through a linkage assembly disposed within the suspension seat 4. When the top column 7 rises relative to the suspension seat 4, the multiple snap-fit ​​sleeves 6 move closer to each other. Specifically, the snap-fit ​​sleeves 6 are arc-shaped, and the multiple snap-fit ​​sleeves 6 are evenly arranged around the circumference, approximately forming a cover shape. The axial direction of the top column 7 coincides with the axial direction of the suspension seat 4. A top plate 8 is disposed at the lower end of the top column 7, and a first elastic element 9 is connected between the upper side of the top plate 8 and the suspension seat 4. The first elastic element 9 is preferably a spring, sleeved on the outside of the top column 7. The linkage function of the linkage assembly is as follows: when the top column 7 rises relative to the suspension seat 4, the multiple snap-fit ​​sleeves 6 move closer to each other, at which time the first elastic element 9 is compressed, and the top column 7 maintains a downward tendency; while when the top column 7 falls relative to the suspension seat 4, the multiple snap-fit ​​sleeves 6 move away from each other, at which time the elastic potential energy of the first elastic element 9 is released.

[0035] As a preferred technical solution of this embodiment, the linkage component includes a linkage block 10 that is movably disposed within the suspension seat 4 and rises and falls synchronously with the top column 7. The linkage block 10 is provided with an inclined slide groove 11, and the sleeve 6 is provided with a connector 12. One end of the connector 12 is movably inserted into the suspension seat 4 and is provided with a sliding pin 13 that matches the inclined slide groove 11. Specifically, the linkage block 10 is provided with a slot on its side, and the inclined slide groove 11 is disposed on the inner wall of the slot. The connector 12 is movably inserted into the side wall of the suspension seat 4 along the radial direction of the suspension seat 4 and is embedded in the slot at this end. The sliding pin 13 at this end is movably connected to the inclined slide groove 11. The upper end of the inclined slide groove 11 is farther from the axial direction of the linkage block 10 than the lower end. In actual use, when the top column 7 rises relative to the suspension seat 4, the linkage block 10 rises synchronously, which causes the sliding pin 13 to move down relative to the inclined slide groove 11. This causes the connecting piece 12 to move closer to the axis of the suspension seat 4 along the radial direction of the suspension seat 4, and the various retaining sleeves 6 will also re-converge to achieve the gripping function. Conversely, when the top column 7 descends relative to the suspension seat 4, the various retaining sleeves 6 will move away from each other.

[0036] As a preferred technical solution in this embodiment, a protruding ring 14 is provided on the top post 7, and a displacement groove 15 matching the protruding ring 14 is provided in the linkage block 10. A second elastic element 16 is provided between the upper side of the protruding ring 14 and the top surface of the displacement groove 15. Specifically, the second elastic element 16 is preferably a spring, sleeved on the outside of the top post 7. The protruding ring 14 is kept at the lowest relative position in the displacement groove 15 by the action of the second elastic element 16. When the sleeve 6 does not grab the bottle cap, the position of the protruding ring 14 in the displacement groove 15 remains unchanged, that is, the linkage block 10 rises synchronously with the top post 7. After the sleeve 6 grabs the bottle cap, the connecting member 12 cannot continue to move, but the top post 7 drives the protruding ring 14 to continue to rise relative to the displacement groove 15, thereby compressing and storing elastic potential energy of the second elastic element 16, which then acts on the sleeve 6 to generate an elastic clamping force, satisfying the function of grabbing the bottle cap while avoiding over-grabbing or loosening.

[0037] As a preferred technical solution in this embodiment, the suspension seat 4 is provided with a limiting component for limiting the movement of the top column 7. When the top column 7 rises to its highest position relative to the suspension seat 4, it is limited by the limiting component. A telescopic unit 17 is provided between the suspension seat 4 and the rotary motor 5. When the telescopic unit 17 is retracted to its shortest length, it triggers the limiting component to cancel the limiting. Specifically, the triggering of the top column 7 occurs when the docking platform closes, the suspension seat 4 descends, causing the top column 7 to abut against the bottle cap, and the suspension seat 4 continues to move downwards relative to the bottle cap. Then, when the docking platform needs to be opened, the bottle cap will lose its support, causing the top column 7 to automatically move downwards. To address the pop-up issue, a limiting component is proposed to limit the top post 7 to its highest position relative to the suspended seat 4, thereby maintaining the secure grip of the cap by the locking component. After the cap is installed, the suspension seat 4 rises, and the cap automatically disengages from the locking component through vertical sliding. Then, after the suspension seat 4 rises above the docking platform, the telescopic unit 17 can retract to trigger the limiting component to cancel the limiting. As a result, the top post 7 can automatically return to its initial position under elastic force, and the sleeves 6 will automatically open. The telescopic unit 17 is preferably a telescopic rod or an electric telescopic rod.

[0038] As a preferred technical solution in this embodiment, the limiting component includes a lever 18 elastically rotatably disposed within the suspension seat 4, a concave annular groove 19 matching the lever 18 provided on the outer wall of the top column 7, and a reset rod 20 fixedly disposed on the outer wall of the telescopic unit 17. One end of the lever 18 extends movably through the side wall of the suspension seat 4 and is vertically corresponding to the reset rod 20. Specifically, the elastic torque on the lever 18 keeps one end close to the side wall of the top column 7. When the top column 7 rises and the concave annular groove 19 corresponds to the lever 18, one end of the lever 18 automatically embeds into the concave annular groove 19. The lower end of the reset rod 20 is conical. When the telescopic unit 17 retracts, the suspension seat 4 rises, and the end of the lever 18 extending from the suspension seat 4 approaches the reset rod 20, and then wedges with the outer wall of the reset rod 20. Thus, the reset rod 20 rotates against the elastic force, and the end of the reset rod 20 inside the suspension seat 4 moves away from the concave annular groove 19 to cancel the limiting of the top column 7. The top column 7 can then automatically rise and reset under the elastic force it receives.

[0039] As a preferred technical solution in this embodiment, the docking platform includes two oppositely arranged flaps 21. The flaps 21 are driven by telescopic cylinders on the support 1. Specifically, the two flaps 21 move relative to each other under the control of the telescopic cylinders controlled by the servo system, thereby realizing the opening and closing action.

[0040] As a preferred technical solution of this embodiment, the capping assembly includes a transition platform 22 provided on the support 1. The transition platform 22 is disposed in close contact with the upper side of the docking platform. A one-way frame 23 for stacking and loading bottle caps is provided on the transition platform 22. A push plate 24 for individually pushing the bottom bottle cap is provided on the side of the transition platform 22 away from the suspension seat 4. The push plate 24 is driven by a telescopic cylinder on the transition platform 22. Specifically, the height of the push plate 24 is just matched with the height of the bottom bottle cap. When the push plate 24 pushes the bottom bottle cap, the other bottle caps are limited within the one-way frame 23 until the push plate 24 is reset, and each bottle cap descends one layer in sequence.

[0041] As a preferred technical solution in this embodiment, the clamping assembly includes two clamping blocks 25 disposed opposite to each other on the bracket 1. The clamping blocks 25 are driven by a telescopic cylinder on the bracket 1. Specifically, the two clamping blocks 25 move relative to each other under the drive of the telescopic cylinder controlled by the servo system, thereby realizing the positioning and clamping action.

[0042] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
