Technical Field

[0001] The invention relates to the technical field of rubber ring mounting, in particular to a rubber ring mounting system. Background Art

[0002] At present, rubber ring conveying roller conveying is a kind of roller conveying method in mechanical conveying, which is widely used for conveying belts, strip-shaped objects and objects placed in trays, especially in glass production lines. The number of rubber ring conveying rollers in one float glass production line is more than one hundred, and each roller has about twenty rubber rings. Since there is no special rubber ring set equipment, the rubber rings are mostly set manually when producing rubber ring rollers. For example, the publication number CN209755083U discloses a rubber ring installation tool, including an opening and closing component and a bearing member, the bearing member carries the rubber ring, and the rubber ring is supported, disassembled and assembled relative to the transmission shaft, and then the outer diameter of the bearing member is changed by the opening and closing component. Among them, the opening and closing component is also disclosed to include a third movable arm, a fourth movable arm and a connecting member, and the opening and closing of the bearing member is realized by manually pressing the third movable arm and the fourth movable arm, thereby realizing one-handed operation and reducing the difficulty of installing the rubber ring.

[0003] Obviously, the above-mentioned rubber ring installation process is a fully manual operation, and the opening and closing components are repeatedly pressed and held for a long time, which is labor-intensive and easily fatigued by the operators, resulting in low efficiency of the rubber ring installation. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a rubber ring fitting system which can reduce labor intensity and improve fitting efficiency, so as to solve the problem of high labor intensity and low efficiency of existing rubber ring fitting.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

When the lowest end of the first loading plate is level with the highest end of the top of the loading slide, since the first loading plate is inclined, the conveying roller automatically slides to the top slide of the loading slide, and slides into the unloading mechanism through the slide, thereby realizing automatic loading of the conveying roller, eliminating manual operation and improving efficiency.

[0025] 2. The coordinated setting of the expansion device and the push-out device not only realizes the expansion of the rubber ring, replacing manual operation without fatigue, but also realizes the pushing of the rubber ring onto the conveying roller, greatly reducing the labor intensity. After the rubber ring is quickly installed, the fixing device, the expansion device and the push-out device can be quickly withdrawn from the conveying roller, greatly improving the installation efficiency of the rubber ring.

[0026] 3. By setting the limiting sleeve and removably fixing the limiting sleeve on the first fixed plate, it can not only prevent the rubber ring expansion claw from expanding too much and causing the rubber ring mounted on the rubber ring expansion claw to break, but also adapt to the different expansion ranges of the rubber ring expansion claw by replacing the limiting sleeves with different inner diameters, thereby adapting to the set of rubber rings of different models, and has strong applicability.

[0027] 4. The outer wall of the rubber ring expansion claw is set in a step shape, and the end with a larger outer diameter of the rubber ring expansion claw is connected to the output end of the expansion cylinder, and a rubber ring is set on the end with a smaller outer diameter of the rubber ring expansion claw. This not only prevents the rubber ring expansion claw from being deformed due to the expansion force of the expansion cylinder, but also prevents the outer diameter of the rubber ring expansion claw from being too large, causing the rubber ring to expand too much and causing the rubber ring to break.

[0028] 5. Through the detachable connection between the push plate wire and the push rod, the push plate with different third through hole diameters can be replaced to adapt to the set of rubber rings of different models, which has strong applicability.

[0029] 6. By setting up the ejection device, the back and forth movement of the set mechanism when receiving the rubber ring is reduced, thus improving efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] The unloading support plate 22 is used to receive the conveying roller 7 that slides down from the loading slide 14, and blocks it in the vertical direction through the baffle plate 23, and then the conveying roller 7 is clamped to the side of the baffle plate 23 by the clamping mechanism 3, so that it is convenient for the later set mechanism 5 to set the rubber ring 8 for the conveying roller 7; when the set mechanism 5 has completed the set of rubber rings 8 for the conveying roller 7, the clamping mechanism 3 is released, and the unloading cylinder 25 is started to retract, so that the conveying roller 7 that slides down on the unloading plate 26 rises along the side of the baffle plate 23. When the lowest end of the unloading plate 26 is level with the highest end of the top of the reinforcing rib 24, since the reinforcing rib 24 is inclined, the highest end of the top of the unloading slide 27 cooperates with the lowest end of the reinforcing rib 24, so that the conveying roller 7 will automatically slide from the reinforcing rib 24 to the top slide of the unloading slide 27, and slide into the unloading hopper 28 through the slide, realizing the automatic unloading and assembly of the conveying roller 7 after the set is completed, eliminating manual operation and improving efficiency.

[0058] The working principle of this embodiment is as follows: a plurality of conveying rollers 7 are installed in the first loading hopper 11. Since the first loading hopper 11 is inclined, the conveying rollers 7 automatically slide from the first loading hopper 11 onto the first loading plate 13, and then the first loading cylinder 12 is started to extend and retract, so that the conveying rollers 7 that slide onto the first loading plate 13 rise along the legs of the loading slide 14. When the lowest end of the first loading plate 13 is level with the highest end of the top of the loading slide 14, since the first loading plate 13 is inclined, the conveying rollers 7 automatically slide onto the top slide of the loading slide 14, and slide into the unloading support plate 22 and the side of the baffle 23 on the unloading mechanism 2 through the slide, and are extended and retracted by the clamping mechanism 13 on the side of the loading slide 14. The conveying roller 7 is pressed against one side of the baffle 23, so that the conveying roller 7 can automatically load the material, eliminating manual operation and improving efficiency; at the same time, the contraction of the swing arm cylinder 64 is started, so that the material receiving trough can receive the rubber ring 8 output from the output end of the second loading hopper 61, and then the swing arm cylinder 64 is pushed to make the swing arm 63 cooperate with the output end of the second loading hopper 61, so that the material receiving trough can receive the rubber ring 8 output from the output end of the second loading hopper 61, and then the swing arm cylinder 64 is pushed to make the swing arm 63 and the rubber ring 8 on the material receiving trough rotate to the sleeve end of the rubber ring expansion claw 522 with the swing arm support 62 as the fulcrum, so as to provide the sleeve mechanism 5 with the rubber ring 8 for loading, replace the manual loading operation, improve the efficiency of rubber ring 8 loading, and reduce labor intensity.

[0059] After the swing arm 63 completes receiving the material and rotates to the sleeve end of the rubber ring expansion claw 522, the expansion cylinder 521 is first started to expand, so that the rubber ring expansion claw 522 at its output end is contracted and the contracted expansion end can pass through the rubber ring 8, and then the first fixed plate 511 is moved on the support 4, so that the expansion end of the rubber ring expansion claw 522 extends into the rubber ring 8, and then the expansion cylinder 521 is started to contract, so that the rubber ring expansion claw 522 at its output end is expanded, and it is ensured that the inner diameter of the rubber ring expansion claw 522 after expansion is greater than the diameter of the conveying roller 7, and then the first fixed plate 511 is moved from the support 4 to the conveying roller 7, and the conveying roller 7 passes through the first through hole 5111 on the first fixed plate 511, the second through hole 5121 on the second fixed plate 512, and the expansion end of the expansion device 52. and the third through hole 5311 on the push plate 531, and after reaching the fitting position, start the expansion cylinder 521 to expand, so that the rubber ring expansion claw 522 at its output end shrinks and fits on the conveying roller 7, and then start the push cylinder 532, and push the push plate 531 through the push rod 533 to push the rubber ring 8 on the rubber ring expansion claw 522 to the conveying roller 7, so as to quickly fit the rubber ring 8, and then start the expansion cylinder 521 to shrink, so that the rubber ring expansion claw 522 expands, and finally the fitting mechanism 5 is withdrawn from the conveying roller 7 to complete the fitting of a single rubber ring 8; and repeat the above-mentioned loading of the rubber ring 8 and the fitting of the rubber ring 8 after loading, so as to realize the fitting of multiple rubber rings 8 on the conveying roller 7, thereby improving the fitting efficiency of a single rubber ring 8, thereby improving the overall fitting efficiency of the rubber ring 8 on the conveying roller 7.

[0060] When all the rubber rings 8 on the conveying roller 7 are installed, the clamping mechanism 3 contracts, and then the unloading cylinder 25 is started to expand and contract, so that the unloading plate 26 passes through the vertical through hole 221 and moves upward, so that the conveying roller 7 after the installation is completed rises along the baffle 23. When the lowest end of the unloading support seat 22 is flush with the highest end of the top of the reinforcing rib 24, the conveying roller 7 will automatically slide from the reinforcing rib 24 to the unloading slide 27, and slide into the unloading hopper 28 through the unloading slide 27 to be installed, forming an integrated production line for installing the rubber rings 8 on the conveying roller 7, replacing the manual installation operation, greatly reducing the labor intensity, and thus improving the efficiency of installing the rubber rings.

[0061] Embodiment 2

[0062] See also Figure 7In this embodiment, on the basis of the first embodiment, a sliding device 15 capable of sliding is further provided on the loading slide 14, and the sliding device 15 includes a pushing cylinder 151, a connecting plate 152, and a movable slide bar 153. The pushing cylinder 151 is horizontally fixed on the loading slide 14, and the horizontal output end of the pushing cylinder 151 is connected to the connecting plate 152. The connecting plate 152 is fixed with a movable slide bar 153 parallel to the top of the loading slide 14. The movable slide bar 153 is arranged below the top of the loading slide 14 when the pushing cylinder 151 is in a contracted state. When the pushing cylinder 151 withdraws, the movable slide bar 153 can be extended in the direction of the extension of the cross section of the top of the loading slide 14.

[0063] For details, see Figure 8 In order to prevent the lowest end position of the top of the loading slide 14 from affecting the operation of the later set mechanism 5, there is a certain gap between the lowest end of the top of the loading slide 14 and the unloading mechanism 2, so a sliding device 15 is provided to support and convey the conveying roller 7 in the gap interval, that is, the conveying roller 7 slides from the lowest end of the top of the loading slide 14 to the moving slide bar 153, and finally the conveying roller 7 slides from the moving slide bar 153 to the unloading mechanism 2, which plays a transition role, in order to prevent the conveying roller 7 from being offset and falling when sliding in the gap interval.

[0064] Embodiment 3

[0065] See also Fig. 9 In this embodiment, based on the first embodiment, the support 4 includes two support bodies 41, a slide bar 42 and a bar gear 43 arranged in parallel. The top and side of the support body 41 are respectively provided with a slide bar 42 and a bar gear 43. The bottom of the first fixed plate 511 is provided with a slide plate (not marked in the figure) that can slide with the slide bar 42. A rotating motor (not marked in the figure) is fixed on the slide plate. The output end of the rotating motor is connected to the rotating gear, and the rotating gear is meshed with the bar gear 43. The rotation of the rotating motor drives the gear to rotate. Since the bar gear is fixed, the slide plate slides on the slide bar 42, thereby driving the first fixed plate 511 to slide.

[0066] Furthermore, the base 21 can also be slidably fixed on the support 4 to adjust the position of the unloading support plate 22 supporting the conveying roller 7 .

[0067] Embodiment 4

[0068] See also Figure 4In this embodiment, on the basis of the first embodiment, a side of the swing arm 63 close to the material receiving baffle 65 is further fixed with an ejector device 66, and the ejector device 66 comprises a third fixed plate 661, an ejector cylinder 662 and a top plate 663. The third fixed plate 661 is fixed to one side of the swing arm 63, and the ejector cylinder 662 is vertically fixed to the fixed plate 661. The output end of the ejector cylinder 662 passes through the material receiving baffle 65 and is connected to a top plate 663 parallel to the material receiving baffle 65. The top plate 663 is driven to move by the telescopic movement of the ejector cylinder 662, so that the rubber ring 8 in the material receiving trough can be pushed onto the rubber ring expansion claw 522. The sleeve mechanism 5 does not need to move back and forth when receiving the rubber ring 8, which reduces the back and forth movement of the sleeve mechanism 5 when receiving the rubber ring 8. The rubber ring 8 can be sleeved on the expansion claw 522 only by the movement of the ejector cylinder 662, which greatly improves the efficiency of sleeved the rubber ring 8 onto the rubber ring expansion claw 522.

[0069] Furthermore, an elastic baffle (not shown) is provided at the output end of the second upper hopper 61. When the swing arm 63 rotates to the output end of the second upper hopper 61, the material receiving baffle 65 presses the elastic baffle and contracts, so that the rubber ring 8 in the second upper hopper 61 slides onto the material receiving groove and the material receiving groove can only ensure the reception of one rubber ring 8. When the swing arm 63 rotates away, the elastic baffle is reset to block the output end of the second upper hopper 61 to prevent the rubber ring 8 of the second upper hopper 61 from falling off.

[0070] Embodiment 5

[0071] Based on the first embodiment, this embodiment has a detachable fixed adjustment plate (not shown) on the leg of the loading slide 14 supporting the conveyor roller 7. By replacing the adjustment plates with different thicknesses, it is prevented that when conveying a conveyor roller 7 with a smaller diameter, the number of conveyor rollers 7 stacked on the first loading plate 13 will exceed that of a single conveyor roller 7, making it impossible to convey a single conveyor roller 7, thereby ensuring that only a single conveyor roller 7 can be stacked on the first loading plate 13 to accommodate the loading of conveyor rollers 7 with different diameters.

[0072] For further information, see Figure 6 The limiting sleeve 514 is detachably fixed to the first fixing plate 511 and the second fixing plate 512 by screws, and the push plate 531 is detachably connected to the push rod 533 by screws, so that sleeves with different inner diameters can be replaced to adapt to different expansion ranges of the rubber ring expansion claws 522, thereby adapting to the set of rubber rings 8 of different models, and has strong applicability.

[0073] Embodiment 6

[0074] This embodiment is based on the fifth embodiment. Figure 6A limiting sleeve 514 is also fixed on the first fixing plate 511 , and the limiting sleeve 514 is coaxially arranged with the first through hole 5111 to prevent the rubber ring expansion claw 522 from expanding too much and causing the rubber ring 8 sleeved on the rubber ring expansion claw 522 to break.

[0075] Furthermore, a limiting sleeve 514 can also be fixed on the second fixed plate 512 and also be coaxial with the first through hole 5111. The limiting sleeve 514 on the first fixed plate 511 and the limiting sleeve 514 on the second fixed plate 511 may have different shapes, but the inner diameters of the two sleeves must be the same, so as to limit the end of the rubber ring expansion claw 522 close to the second fixed plate 512, thereby limiting the two positions of the rubber ring expansion claw 522 and preventing the limitation of one position from causing deformation of the rubber ring expansion claw 522 due to the expansion force of the expansion cylinder 521.

[0076] Furthermore, the rubber ring expansion claw 522 is arc-shaped, and the outer wall of the rubber ring expansion claw 522 is a step-shaped rubber ring expansion claw 522. The outer diameter of one end of the rubber ring expansion claw 522 extending through the first fixed plate 511 away from the second fixed plate 512 is smaller than the outer diameter of the other end of the rubber ring expansion claw 522. The end with a larger outer diameter of the rubber ring expansion claw 522 is connected to the output end of the expansion cylinder 521, and the end with a smaller outer diameter of the rubber ring expansion claw 522 is sleeved with a rubber ring 8. This not only prevents the rubber ring expansion claw 522 from being deformed due to the expansion force of the expansion cylinder 521, but also prevents the outer diameter of the rubber ring expansion claw 522 from being too large, causing the rubber ring 8 to expand too much, thereby preventing the rubber ring 8 from breaking.
