Description

Technical Field

[0001] This invention relates to the field of overhead conveying equipment technology, specifically an overhead conveying device for filling bottles in a filling production line. Background Technology

[0002] In the production of saline solution in the pharmaceutical industry, the conveying of filling bottles is fundamental to connecting various process steps (such as cleaning, filling, capping, and labeling). Currently, most mainstream filling production lines adopt ground-based conveying systems. However, since filling lines are usually composed of multiple independent process equipment (such as bottle rinsing machines, filling machines, and capping machines) connected in series, the conveyor belts between each piece of equipment are often physically separated by the equipment itself, forming multiple independent conveying sections. To ensure that the bottles travel stably on each conveyor section without shifting or tipping, width-limiting plates (or guide rails, or guide plates) must be installed on both sides of each conveyor belt. These are often manually adjusted and fixed. There are several common sizes of saline bottles. When the production line needs to process bottles of different diameters, operators must manually adjust the width-limiting plates on each independent conveyor belt on the production line. The entire filling line's conveyor system requires the adjustment of dozens or even hundreds of width-limiting plates. This is not only a huge workload and time-consuming and labor-intensive, but also makes it difficult to guarantee the accuracy of manually adjusting the width-limiting plates. It is not easy to adjust them all at once, and operators often need to perform secondary or even multiple repeated corrections, making the adjustment of the conveyor system quite troublesome when changing bottle sizes.

[0003] While there are some existing suspended conveying solutions that suspend bottles by clamping the bottle mouth or neck, the clamps of existing suspended conveying devices, with their spring-adaptive clamping structure, can adapt to the bottle necks of different sizes, but their clamping stability is not high. On the other hand, clamps with high clamping stability are difficult to adjust when changing sizes, generally requiring manual adjustment one by one or direct replacement with clamps of different sizes. To address this, we provide a suspended conveying device for filling bottles in a filling production line. Summary of the Invention

[0004] The purpose of this invention is to provide a bottle suspension and conveying device for a filling production line to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A bottle suspension conveying device for a filling production line includes a suspension track, with suspension rods slidably mounted at equal intervals on the suspension track, chain ropes installed between the suspension rods, a drive module installed at the end of the suspension track for driving the chain rope transmission, and multiple mounting brackets installed on the suspension track.

[0007] Multiple clamping assemblies are provided, and each clamping assembly corresponds one-to-one with a multiple lifting rod. The clamping assembly is installed below the corresponding lifting rod. Each clamping assembly includes a base plate, one end of which is rotatably connected to two clamping arms. One end of each clamping arm is fixedly mounted with a surrounding plate. An adjustment module is fixedly mounted on the inner side wall of the surrounding plate. Three clamping modules are slidably mounted on one side of the adjustment module. The clamping modules are used to support the flange of the bottleneck. A hoop is slidably connected to the base plate to constrain the two clamping arms. An adjustment module is installed below the base plate to drive the adjustment module.

[0008] The adjustment components are provided in several parts, and the adjustment module adjusts the spacing between the multiple clamping modules when passing through the adjustment components;

[0009] Several open frames and fastening frames are provided, and the open frames and fastening frames are used to drive the hoop frame to move on the base plate.

[0010] Furthermore, the adjustment module includes an arc frame, which is fixedly installed on the enclosure. Three equal-spaced sliding grooves are provided on the top surface of the arc frame, each corresponding to one of the three clamping modules. Each clamping module includes a mounting base, one end of which is slidably connected to the corresponding sliding groove. One end of the enclosure is rotatably connected to an externally threaded rod, one end of which is fixedly fitted with a bevel gear. The other end of the externally threaded rod is screwed onto a threaded sleeve, one end of which is fixedly connected to an adjacent mounting base.

A sliding column is fixedly installed on the top side of one end of the mounting base, and the sliding groove is slidably connected to the sliding column on the adjacent clamping module. The middle position of the linkage frame is fixedly installed to the middle mounting base among the three mounting bases. A cover plate for shielding the area above the arc frame is fixedly installed on the inner wall of the enclosure.

[0011] Furthermore, one end of the linkage frame is provided with a horizontal groove, and one end of the top surface of the arc frame is fixedly installed with a sliding column, which is slidably connected to the horizontal groove.

[0012] Furthermore, the other end of the mounting base is rotatably connected to a compression roller, and the top side of the other end of the mounting base is rotatably connected to a support roller. The support roller is used to support the flange of the bottleneck, and the compression roller is used to compress the bottleneck.

[0013] Furthermore, the adjustment module includes an internal threaded seat, which is fixedly installed on the bottom surface of one end of the seat plate. An external threaded rod is screwed onto the bottom end of the internal threaded seat. A positioning gear is fixedly installed on one end of the external threaded rod. A shaft is rotatably connected to the bottom surface of the other end of the seat plate. One end of the shaft is slidably inserted into the other end of the external threaded rod. A bevel gear is fixedly installed on the other end of the shaft. The bevel gear is used to mesh with two bevel gears when the two clamping arms are in contact.

[0014] Furthermore, the adjusting assembly includes a hanger, the top of which is detachably and fixedly installed with a mounting bracket at a corresponding position. A second clamping plate is installed at the bottom of the hanger, and a first clamping plate is provided on one side of the second clamping plate. A lower toothed plate and an upper toothed plate are fixedly installed on one side of the first clamping plate. The lateral distance between the lower toothed plate and the upper toothed plate is wider than the thickness of the positioning gear by millimeters to millimeters. The lower toothed plate and the upper toothed plate are used to mesh with the positioning gear.

[0015] Furthermore, both ends of the clamping plate one are evenly fixedly installed with insert rods, the insert rods are slidably inserted into the clamping plate two, one end of the insert rod has a thread on its outer side wall, and one end of the insert rod is screwed with a nut.

[0016] Furthermore, a compression spring is fixedly installed between the two clamping arms in the clamping assembly, a lever is fixedly installed at the top of the clamp, the open frame is used to push the clamp towards one end of the base plate via the lever, the fastening frame is used to push the clamp towards the other end of the base plate via the lever, a magnetic block is fixedly installed on the outer wall of the clamping arm, the magnetic block is used to attract the clamp, and the outer wall of the other end of the clamping arm converges towards the middle, thereby facilitating the clamp to move the two clamping arms closer together when sliding.

[0017] Furthermore, the bottom end of the boom is rotatably connected to a rocker arm, the bottom end of the rocker arm is fixedly installed with the top end of the vertical rod in the corresponding clamp assembly, the bottom end of the boom is provided with a limiting groove, the top end of the rocker arm is provided with an opening groove, a core rod is movably arranged in the opening groove, and the core rod is equipped with several lifting frames, which are used to push the core rod upward.

[0018] Furthermore, the suspended track is equipped with a feeding conveyor belt and a discharging conveyor belt, and the feeding conveyor belt and the discharging conveyor belt are inclined relative to the adjacent portion of the suspended track.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. By adjusting the settings of the components and modules, the lower and upper toothed plates are moved along the axis of the positioning gear by adjusting the distance between clamping plates one and two in the adjustment component. When the clamping assembly passes the adjustment component, the positioning gear meshes with the corresponding toothed plate to drive the external thread rod one to rotate, thereby realizing that the radial distance of the three clamping modules is automatically adjusted according to the change of the bottle neck diameter. When changing the production line specifications, the conveying device only needs to adjust the distance between the two clamping plates, or directly clamp the bottle neck of the target specification between the two clamping plates. The operation is convenient and no secondary adjustment is required. When the clamping assembly passes the adjustment component, it is driven and automatically adjusted into place, reducing manual operation and making it more convenient. This makes it more suitable for production scenarios that require frequent changes in production specifications.

[0021] 2. By setting up the clamping assembly, an open frame and a fastening frame are fixedly arranged on the conveying path of the suspended track. Both have inclined guide structures on their bottom sides. When the clamping assembly passes by, the open frame pushes the lever on the hoop to slide the hoop, releasing the constraint on the two clamping arms, and the clamping arms open in conjunction with the compression spring. When passing the fastening frame, the hoop is pushed to slide in the opposite direction, causing the two clamping arms to close, realizing the automatic switching of the clamping open and closed state. Combined with the setting of the clamping module, when clamping bottles of different sizes, the posture of the two clamping arms is always consistent during clamping. During clamping, the hoop provides rigid constraint on the clamping arms, effectively reducing or avoiding the clamping arms from opening under external force, making the clamping more stable, and achieving flexible adjustment of clamping specifications while maintaining clamping stability.

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1 to 8In this embodiment of the invention, a bottle suspension conveying device for a filling production line includes a suspension track 100, on which hanging rods 120 are equidistantly slidably mounted, and chain ropes 130 are installed between the multiple hanging rods 120. A drive module 110 is installed at the end of the suspension track 100, and the drive module 110 is used to drive the chain ropes 130. Multiple mounting brackets 140 are installed on the suspension track 100. The device also includes an adjustment component 300, a clamping component 400, and an open frame 500. Multiple clamping components 400 are provided, and each clamping component 400 corresponds one-to-one with a multiple hanging rod 120. The clamping components 400 are installed below the corresponding hanging rod 120. Each clamping component 400 includes a base plate 410, and two clamping arms 420 are rotatably connected to one end of the base plate 410. One end is fixedly installed with a surrounding plate 422. An adjustment module 460 is fixedly installed on the inner side wall of the surrounding plate 422. Three clamping modules 470 are slidably installed on one side of the adjustment module 460. The clamping module 470 is used to support the flange of the bottleneck. A hoop 430 is slidably connected on the seat plate 410. The hoop 430 is used to constrain the two clamping arms 420. An adjustment module 440 is installed below the seat plate 410. The adjustment module 440 is used to drive the adjustment module 460. Several adjustment components 300 are provided. When the adjustment module 440 passes through the adjustment components 300, it adjusts the spacing between the multiple clamping modules 470. Several open frames 500 and fastening frames 600 are provided respectively. The open frames 500 and fastening frames 600 are used to drive the hoop 430 to move on the seat plate 410.

[0036] Specifically, during operation of this device, the layout of the suspension track 100 is arranged according to actual production needs. The drive module 110 drives the chain rope 130 for transmission, thereby driving multiple booms 120 to travel along the suspension track 100 at a predetermined speed. The booms 120 are set up through the open frame 500 and the fastening frame 600, which are set on the travel path of the booms 120. When the boom 120 passes the open frame 500, the two clamping arms 420 in the corresponding clamping assembly 400 gradually open, and the clamping assembly 400 becomes open. When the boom 120 passes the fastening frame 600, the two clamping arms 420 close, and the clamping assembly 400 returns to the clamping state.

[0037] Please see Figures 5 to 8In this embodiment, the adjustment module 460 includes an arc frame 464, which is fixedly installed on the surrounding plate 422. The top surface of the arc frame 464 has three equally spaced sliding grooves 465, each corresponding to one of the three clamping modules 470. Each clamping module 470 includes a mounting base 471, one end of which is slidably connected to the corresponding sliding groove 465. One end of the surrounding plate 422 is rotatably connected to a threaded rod 461. One end of the threaded rod 461 is fixedly mounted with a bevel gear 462, and the other end of the threaded rod 461... A threaded sleeve 463 is screwed into the mounting bracket 471 located adjacent to it. A linkage frame 467 is provided above the arc frame 464. Sliding grooves 468 are provided at both ends of the top surface of the linkage frame 467. A sliding column 474 is fixedly installed on the top side of one end of the mounting bracket 471. The sliding groove 468 is slidably connected to the sliding column 474 on the clamping module 470 located adjacent to it. The middle position of the linkage frame 467 is fixedly installed with the middle mounting bracket 471 among the three mounting brackets 471. A device for... For the cover plate obstructing the top of the arc frame 464, a horizontal groove 469 is provided at one end of the linkage frame 467. A sliding column 466 is fixedly installed at one end of the top surface of the arc frame 464, and the sliding column 466 is slidably connected to the horizontal groove 469. A pressing wheel 473 is rotatably connected to the other end of the mounting base 471, and a support wheel 472 is rotatably connected to the top side of the other end of the mounting base 471. The support wheel 472 is used to support the flange of the bottleneck, and the pressing wheel 473 is used to press the bottleneck. The adjustment module 440 includes an internal thread seat 441, which is fixedly installed on the base plate 410. At one end of the bottom surface, the bottom end of the internal threaded seat 441 is screwed to the external threaded rod 443. One end of the external threaded rod 443 is fixedly mounted with a positioning gear 444. The bottom surface of the other end of the seat plate 410 is rotatably connected to the shaft 442. One end of the shaft 442 is slidably inserted into the other end of the external threaded rod 443. The other end of the shaft 442 is fixedly mounted with a bevel gear 445. The bevel gear 445 is used to mesh with two bevel gears 462 when the two clamping arms 420 are in contact. The radial transmission ratio between the external threaded rod 443 and the threaded sleeve rod 463 is two to one.

[0038] Specifically, for different specifications of filling bottles, when it is necessary to change the distance between the central axis of multiple clamping modules 470 and the surrounding plate 422, the clamping assembly 400 is in a clamping state by adjusting the adjusting component 300 and by arranging the fastening bracket 600. At this time, bevel gear 1 445 and bevel gear 2 462 mesh. When the positioning gear 444 passes through the adjusting component 300, it is driven to rotate. The positioning gear 444 drives the external threaded rod 1 443 and the shaft 442 to rotate. The shaft 442 body drives the external threaded rod 2 463 through bevel gear 1 445 and bevel gear 2 462. 1. Rotation, through the engagement of the external threaded rod 461 and the threaded sleeve rod 463, drives the corresponding mounting seat 471 to move axially along the external threaded rod 461. The movement of the mounting seat 471 pushes the connecting frame 467 to slide through the sliding column 474, so that the connecting frame 467 slides along the length direction of a sliding groove 465 at the middle position on the arc frame 464. The sliding of the connecting frame 467 drives the other two mounting seats 471 to slide along their respective corresponding sliding grooves 465, thereby realizing that multiple mounting seats 471 on the clamping assembly 400 synchronously converge or disperse towards the center, realizing the adjustment of the effective clamping radius between multiple mounting seats 471;

[0039] Please see Figure 9 In this embodiment, the adjustment component 300 includes a hanger 310. The top of the hanger 310 is detachably and fixedly installed with the mounting bracket 140 at the corresponding position. A second clamping plate 330 is installed at the bottom of the hanger 310. A first clamping plate 320 is provided on one side of the second clamping plate 330. A lower toothed plate 340 and an upper toothed plate 350 are fixedly installed on one side of the first clamping plate 320. The lateral distance between the lower toothed plate 340 and the upper toothed plate 350 is 1 mm to 2 mm wider than the thickness of the positioning gear 444, so that the positioning gear 444 is closer to the lower toothed plate 340 and the upper toothed plate 350. There is a margin to accommodate the vibration of the positioning gear 444 during operation. The surface of the extrusion wheel 473 has a rubber layer to accommodate the aforementioned margin, so as to facilitate a tight fit between the extrusion wheel 473 and the bottle body and avoid or reduce bottle shaking. The lower tooth plate 340 and the upper tooth plate 350 are used to mesh with the positioning gear 444. The two ends of the clamping plate 320 are evenly fixedly installed with the insertion rod 321. The insertion rod 321 is slidably inserted into the clamping plate 330. The outer wall of one end of the insertion rod 321 is threaded, and a nut is screwed onto one end of the insertion rod 321.

[0040] Specifically, by setting clamping plate 2 330 and clamping plate 1 320, when adjusting the clamping radius of clamping assembly 400, the neck of the target bottle can be directly clamped between clamping plate 2 330 and clamping plate 1 320. Rotating the nut causes clamping plate 1 320 to move, thus making the distance between clamping plate 2 330 and clamping plate 1 320 equal to the diameter of the target bottle neck. The movement of clamping plate 1 320 drives the lower toothed plate 340 and upper toothed plate 350 to move along the axis of the external threaded rod 1 443. Figure 8 (Taking the left and right directions as an example) In the normal state, i.e., when the external thread rod 443 is adjusted to the correct position, the positioning gear 444 passes through the gap between the lower toothed plate 340 and the upper toothed plate 350 when it passes the adjusting component 300. The positioning gear 444 does not rotate. However, when the adjusting component 300 is adjusted, for example, when the distance between the clamping plate 330 and the clamping plate 320 increases, the lower toothed plate 340 and the upper toothed plate 350 move to the right synchronously. This causes the positioning gear 444 to mesh with the lower toothed plate 340 the next time it passes the adjusting component 300, thereby allowing the positioning gear 444 to rotate. The external threaded rod 443 rotates forward, and through its engagement with the internal threaded seat 441, it rotates forward and moves to the right, causing the positioning gear 444 to move to the right. This continues until the positioning gear 444 moves back between the lower gear plate 340 and the upper gear plate 350 without contacting either, at which point it stops rotating. Similarly, when the clamping plate 320 moves to the left, the positioning gear 444 meshes with the upper gear plate 350, causing the external threaded rod 443 to rotate in the opposite direction and move to the left. This achieves the desired movement distance between the external threaded rod 443 and the clamping plate 320. 20. The lower toothed plate 340 and the upper toothed plate 350 move at the same distance, that is, the moving distance of the external threaded rod 443 is consistent with the change value of the bottleneck diameter. The rotation of the external threaded rod 443 drives the external threaded rod 461 to rotate, thereby driving the threaded sleeve rod 463 to move along the axis of the external threaded rod 461. Through the setting of a radial transmission ratio of 2:1 between the external threaded rod 443 and the threaded sleeve rod 463, that is, the radial moving distance of the external threaded rod 443 is 2:1 to the axial moving distance of the threaded sleeve rod 463. When the moving distance of the external threaded rod 443 is the bottleneck diameter... When the diameter changes, the moving distance of the mounting base 471 corresponds to the change in the radius of the bottleneck, thus enabling the mounting base 471 to adapt to the new bottle bottleneck after adjustment. That is, when it is necessary to change to a different specification of bottle during the production process, a sample bottle can be taken directly and the bottleneck can be clamped between clamping plate 320 and clamping plate 330. When the clamping assembly 400 passes the adjusting assembly 300, the position of the clamping module 470 on the clamping assembly 400 is automatically adjusted, so that it is not necessary to manually adjust the position of the clamping module 470 in multiple clamping assemblies 400 in sequence, which facilitates and quickly adjusts the production specifications of the production line.

[0041] Example 1

[0042] like Figures 5 to 10 As shown, in this embodiment, a compression spring 450 is fixedly installed between the two clamping arms 420 in the clamping assembly 400, a lever 431 is fixedly installed at the top of the clamp 430, an open frame 500 is used to push the clamp 430 towards one end of the seat plate 410 via the lever 431, a fastening frame 600 is used to push the clamp 430 towards the other end of the seat plate 410 via the lever 431, a magnet 421 is fixedly installed on the outer wall of the clamping arm 420, the magnet 421 is used to attract the clamp 430, and the outer wall of the other end of the clamping arm 420 converges towards the middle, so that the clamp 430 can move the two clamping arms 420 closer together when sliding.

[0043] In this embodiment, both ends of the bottom sides of the open frame 500 and the fastening frame 600 are provided with inclined guide structures. When the clamp assembly 400 passes the open frame 500, the open frame 500 pushes the lever 431 to move to the left, and the clamp 430 releases its grip on the clamping arm 420. The two clamping arms 420 open under the elastic force of the compression spring 450. When the clamp assembly 400 passes the fastening frame 600, the lever 431 pushes the clamp 430 to move to the right. The clamp 430 moves to the right and squeezes the two clamping arms 420, causing the clamping arms 420 to close. With the setting of the magnetic block 421, after the clamp 430 moves into place, the magnetic block 421 attracts the clamp 430. The attraction of the magnetic block 421 prevents the clamp 430 from sliding under the vibration of the clamp assembly 400 during operation. The actual position and number of the open frame 500 and the fastening frame 600 on the suspension track 100 are arranged according to the actual needs of the production line.

[0044] Example 2

[0045] like Figure 11 As shown, in this embodiment, the bottom end of the boom 120 is rotatably connected to a rocker arm 121. The bottom end of the rocker arm 121 is fixedly installed with the top end of the vertical rod 411 in the corresponding clamp assembly 400. The bottom end of the boom 120 is provided with a limiting groove 123, and the top end of the rocker arm 121 is provided with an opening groove 124. A core rod 122 is movably arranged in the opening groove 124. The core rod 122 is equipped with several lifting frames 200. The lifting frames 200 are used to push the core rod 122 upward. The suspension track 100 is equipped with a feeding conveyor belt 700 and a discharging conveyor belt 800. The feeding conveyor belt 700 and the discharging conveyor belt 800 are inclined relative to the adjacent suspension track 100.

[0046] In specific implementation, with the rocker arm 121 in its natural state, the core rod 122 rests at the bottom of the opening slot 124. At this time, the rotation axis of the core rod 122 coincides with that of the top of the rocker arm 121. Therefore, during the climbing or descending section of the suspension track 100, the lifting rod 120 is in an inclined state, but the rocker arm 121 is in a free-hanging state. This facilitates the clamping assembly 400 keeping the bottle vertical after clamping it. With the lifting frame 200 in place, when the lifting rod 120 passes through the lifting frame 200, the lifting frame 200... The core rod 122 is pushed upward, causing it to move to the top of the limiting groove 123, thereby "straightening" the connection between the lifting rod 120 and the rocker arm 121 and preventing the rocker arm 121 from tilting relative to the lifting rod 120. On the suspension track 100, a lifting frame 200 is also installed at the position where the adjusting component 300 is installed, so that the rocker arm 121 remains vertical when the external thread rod 443 passes through the adjusting component 300, which facilitates the lateral overlap between the positioning gear 444 and the lower gear plate 340 to maintain engagement.

[0047] The feeding conveyor belt 700 arranges empty bottles linearly at equal intervals and transports them forward. When the clamping assembly 400 moves to the position of the corresponding feeding conveyor belt 700, it remains in an open state. The tilting setting of the feeding conveyor belt 700 causes the empty bottle to move between the two adjustment modules 460 in the corresponding clamping assembly 400. Then, the clamping assembly 400 returns to the clamping state to hold the neck of the empty bottle. Similarly, in the reverse direction, the clamping assembly 400 releases the filled bottle and places it on the unloading conveyor belt 800 for unloading. Specifically, at least one of the several adjustment components 300 is installed in the suspension track 100 on the transport route between the unloading conveyor belt 800 and the feeding conveyor belt 700. This allows the empty clamping assembly 400 to pass through an adjustment component 300 before passing the feeding conveyor belt 700, thereby adjusting or calibrating the clamping radius of the clamping assembly 400.

[0048] In this invention, the feeding conveyor belt 700 also includes an electrically controlled stop bar and a manually adjustable width limiting plate. The electrically controlled stop bar is used to control the spacing between empty bottles on the feeding conveyor belt 700, and the width limiting plate is adjusted according to the bottle diameter.
