Description

Technical Field

[0001] The invention relates to the technical field of suspension conveying systems, in particular to suspension conveying equipment and a feeding method for processing annular rubber workpieces. Background Art

[0002] The intelligent overhead conveying system is an upgraded version of the traditional overhead conveying system. It mainly realizes intelligent and efficient material transportation by integrating sensors, the Internet of Things, and automated control technologies. Its core structure includes a track and sling system, a drive and control unit, a sensing and feedback device, and a data interaction system. Currently, the intelligent overhead conveying system is widely used in the rubber products industry. At present, this type of intelligent overhead conveying device has certain shortcomings when conveying annular rubber workpieces: Existing slings used for overhead conveying generally use hooks to hold the material. However, for semi-finished products, the material itself is soft and easily deformed. The contact area between the hook and the material is under high pressure and continuous pressure during the conveying process, which can easily cause deformation of the material contact point. In addition, the hook's lack of stability in holding the material, and the shaking and vibration during movement increase the probability of such deformation. Secondly, the semi-finished rubber material may need to be transported to a vulcanization or spraying station. Compared with other locations, the contact point between the hook and the material has a dead angle during heating or spraying, which reduces production quality. Summary of the Invention

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] As introduced in the background technology, in order to solve the deficiencies in the prior art and to solve the above technical problems, the present application proposes a suspension conveying device and a feeding method for processing annular rubber workpieces.

[0032] Example 1: Please refer to Figure 1-Figure 3 A suspended conveying device includes a track 1 and a sling 2 mounted on the track 1, and also includes an output rack 3 fixed below the track 1. The sling 2 includes a bracket 4, a transmission assembly 5 mounted on the bracket 4, and two symmetrically distributed supports 6 mounted at the bottom end of the bracket 4;

[0033] The support 6 includes a plurality of movable rollers 61 distributed in an annular array, each of the plurality of movable rollers 61 is used to support the annular rubber workpiece from the inside, and the support 6 also includes an adjustment component 62 for simultaneously adjusting the positions of the plurality of movable rollers 61;

[0034] The transmission assembly 5 is in transmission connection with the output rack 3 and a plurality of movable rollers 61, and the output rack 3 and the transmission assembly 5 are used to drive the movable rollers 61 to rotate;

[0035] Before the sling 2 transports the annular rubber workpiece, the annular rubber workpiece is sleeved on the outside of multiple movable rollers 61. The movable rollers 61 provide support for the annular rubber workpiece. When the sling 2 moves with the track 1, the output rack 3 forces the transmission assembly 5 to operate. When the transmission assembly 5 operates, it forces the multiple movable rollers 61 to rotate, thereby driving the annular rubber workpiece to rotate, thereby changing the contact point between the movable rollers 61 and the annular rubber workpiece.

[0036] Among them, a chain is provided inside the track 1, and the chain is driven by the servo control system of the track 1, and drives multiple groups of slings 2 to move at the same time. Two supports 6 are respectively installed with two annular rubber workpieces, and at least three movable rollers 61 are set. When in use, the annular rubber workpiece is sleeved on the outside of the multiple movable rollers 61, and the movable rollers 61 provide a supporting effect on the inside of the annular rubber workpiece. When the sling 2 moves, the output rack 3 drives the transmission assembly 5. After the transmission assembly 5 is running, it drives the two groups of movable rollers 61 at the bottom of the sling 2 to rotate simultaneously. When the movable rollers 61 rotate, the friction force is used to drive the annular rubber workpiece to rotate, that is, the annular rubber workpiece rotates while moving with the sling 2. When the annular rubber workpiece rotates, the contact point between the movable roller 61 and the annular rubber workpiece changes, that is, the support point of the annular rubber workpiece by the movable roller 61 changes;

[0037] By arranging multiple annularly distributed movable rollers 61 on the sling 2 instead of hooks to lift the annular rubber workpiece, the inside of the annular rubber workpiece can be supported, the stability is improved, and the vibration and shaking during the transportation process are reduced. In addition, during the transportation process, the output rack 3 and the transmission assembly 5 can drive each movable roller 61 to rotate synchronously, so that the annular rubber workpiece can rotate while moving, thereby avoiding deformation after continuous pressure at the same position. It also makes the annular rubber workpiece more uniform during heating or spraying, avoids dead corners, and improves processing quality.

[0038] Example 2: See Figure 1 and Figure 2 , different from the above embodiment, a hanger 7 is fixed to the top of the track 1, the output rack 3 is arranged below the track 1 and has the same shape as the track 1, a plurality of evenly distributed connecting rods 8 are fixed between the output rack 3 and the track 1, and the bracket 4 includes a vertical rod 41 and a horizontal tube 42. The top of the vertical rod 41 is installed on the track 1, and the horizontal tube 42 passes through the bottom end of the vertical rod 41 and is fixed to the vertical rod 41. A notch 43 is opened at the top of the horizontal tube 42, and the support 6 is respectively installed at both ends of the horizontal tube 42.

[0039] Among them, the hanger 7 is fixed on the top of the workshop to ensure the stability of the track 1. In actual application, the position of the tooth block on the surface of the output rack 3 is set according to demand to control the rotation of the annular rubber workpiece at an appropriate frequency and position. The horizontal tube 42 and the vertical rod 41 are distributed vertically, and the connection point between the horizontal tube 42 and the vertical rod 41 is located at the middle point of the horizontal tube 42.

[0040] Example 3, see Figure 3-Figure 7, different from the above embodiment, the support 6 also includes an angle iron 63 and a transmission rod 64 that match the movable roller 61, one end of the transmission rod 64 passes through the angle iron 63 and is rotatably connected to the angle iron 63, and a first bevel gear 65 is fixed to the end of the transmission rod 64 near the angle iron 63, and a base shaft 66 is fixed to the middle of the movable roller 61, the base shaft 66 passes through the angle iron 63 and is rotatably connected to the angle iron 63, and a second bevel gear 67 is fixed to the end of the base shaft 66, and the second bevel gear 67 is meshed with the first bevel gear 65, and the transmission rod 64 is away from the angle iron 63. One end passes through the interior of the cross tube 42 and is rotatably connected to the cross tube 42, and the transmission rod 64 is located inside the cross tube 42 and is fixed with a driven Bevel gear 68, the transmission assembly 5 includes a vertical shaft 51 located on the vertical rod 41 and a horizontal shaft 52 located inside the horizontal tube 42, the vertical shaft 51 is movably mounted on the vertical rod 41 through a main bearing seat 53, an output gear 54 is fixed to the top of the vertical shaft 51, the output gear 54 is engaged with the output rack 3, the bottom end of the vertical shaft 51 extends into the horizontal tube 42 through the recess 43 and is fixed with a third bevel gear 55, the horizontal shaft 52 is rotatably connected to the horizontal tube 42, a fourth bevel gear 56 is fixed to the middle of the horizontal shaft 52, the fourth bevel gear 56 is engaged with the third bevel gear 55, and a driving bevel gear 57 is fixed to both ends of the horizontal shaft 52, the driving bevel gear 57 is engaged with the driven bevel gear 68.

[0041] Among them, multiple transmission rods 64 are evenly distributed radially, and the driven bevel gears 68 at the ends of multiple transmission rods 64 on a support 6 are simultaneously engaged with the active bevel gear 57 at one end of the horizontal shaft 52. When in use, when the spreader 2 moves, the output gear 54 moves along the surface of the output rack 3. After the output gear 54 rotates, it drives the vertical shaft 51 to rotate. When the vertical shaft 51 rotates, it drives the third bevel gear 55 to rotate. When the third bevel gear 55 rotates, it drives the fourth bevel gear 56 to rotate. When the fourth bevel gear 56 rotates, it drives the horizontal shaft 52 to rotate. The horizontal shaft 52 rotates. When the driving bevel gear 57 rotates, the driving bevel gear 57 rotates, and when the driving bevel gear 57 rotates, the multiple driven bevel gears 68 rotate. When the driven bevel gear 68 rotates, the transmission rod 64 rotates. When the transmission rod 64 rotates, it drives the first bevel gear 65 to rotate. When the first bevel gear 65 rotates, it drives the second bevel gear 67 to rotate. When the second bevel gear 67 rotates, it drives the base shaft 66 to rotate. When the base shaft 66 rotates, it drives the movable roller 61 to rotate. When the multiple movable rollers 61 rotate, the annular rubber workpiece is driven to rotate, thereby changing the support point inside the annular rubber workpiece.

[0042] By setting up the transmission assembly 5 and the output rack 3, when the sling 2 moves, the output rack 3 drives the transmission assembly 5 to operate, thereby driving the multiple movable rollers 61 to rotate simultaneously, which is conducive to driving the annular rubber workpiece to rotate, thereby changing the support point, avoiding deformation of the annular rubber workpiece, and ensuring production quality.

[0043] Example 4, see Figure 5-Figure 8 , different from the above embodiment, the adjustment component 62 includes a plurality of guide rails 621 distributed in an annular array, one end of the guide rail 621 is fixed to the cross tube 42, a radial slider 622 is slidably connected in the guide rail 621, a connecting shaft 623 is fixed on the surface of the radial slider 622, and the connecting shaft 623 is fixedly connected to the angle iron 63, the adjustment component 62 also includes a rotating frame 624 rotatably connected to the cross tube 42, and a plurality of arc frames 625 distributed in an annular array are fixed on the rotating frame 624, and the plurality of arc frames 625 is respectively sleeved on each connecting shaft 623, and a worm gear 626 is fixed on one side of the rotating frame 624. The worm gear 626 is movably sleeved on the cross tube 42. A worm 627 is engaged with the top of the worm gear 626. Both ends of the worm 627 are movably mounted on the guide rail 621 through a secondary bearing seat 628. The transmission rod 64 includes a sleeve 641 and an insertion rod 642 inserted in the sleeve 641. The insertion rod 642 is provided with evenly distributed bar-shaped tooth blocks, and the sleeve 641 is provided with tooth grooves matching the bar-shaped tooth blocks.

[0044] The number of guide rails 621 and arc frames 625 is the same as the number of movable rollers 61 and corresponds one to one. When in use, different batches of annular rubber workpieces have different diameters. When conveying annular rubber workpieces of different diameters, the worm 627 is rotated. When the worm 627 rotates, the worm gear 626 is driven to rotate. When the worm gear 626 rotates, the rotating frame 624 is driven to rotate. When the rotating frame 624 rotates around the transverse tube 42, it simultaneously drives multiple arc frames 625 to swing. When the arc frame 625 swings, it pushes the connecting shaft 623, thereby causing the radial slider 622 to slide along the slide rail. At this time, the connecting shaft 623 also drives the angle iron 63 to move when the radial slider 622 moves. When the angle iron 63 moves, it drives the sleeve 641 to move, so that the sleeve 641 and the insertion rod 642 slide relative to each other. When the angle iron 63 moves, it also drives the movable roller 61 to move. When multiple movable rollers 61 move radially to different positions at the same time, they can adapt to annular rubber workpieces of different diameters.

[0045] By setting up the adjustment component 62, multiple movable rollers 61 on the support 6 can be driven to move radially at the same time, and then the position of the movable roller 61 can be adjusted, so that the movable roller 61 can adapt to annular rubber workpieces of different diameters, which is more practical, and the adjustment will not affect the driving of the annular rubber workpiece by the movable roller 61.

[0046] Example 5, see Figure 8, different from the above embodiment, a transmission gear 9 is fixed to the end of the worm 627, and the adjustment component 62 also includes an incomplete rack 10 that matches the position of the transmission gear 9, and a pressure plate 11 is fixed to the end of the incomplete rack 10. A slide groove 12 is provided on the top of the incomplete rack 10, and a strip slider 13 is slidably connected in the slide groove 12. One end of the strip slider 13 extends to the outside of the slide groove 12 and is fixedly connected to the guide rail 621. A spring 14 is provided inside the slide groove 12, and the two ends of the spring 14 are fixedly connected to the pressure plate 11 and the strip slider 13 respectively.

[0047] Among them, in the initial state, the incomplete rack 10 is not engaged with the transmission gear 9. When the annular rubber workpiece is loaded and unloaded, the operator or the robotic arm presses the pressure plate 11. When the pressure plate 11 moves, it drives the incomplete rack 10 to slide and compresses the spring 14. When the incomplete rack 10 slides, it meshes with the transmission gear 9 and pushes the transmission gear 9 to rotate. When the transmission gear 9 rotates, it drives the worm 627 to rotate, thereby causing the adjustment component 62 to operate. When the adjustment component 62 operates, it drives the multiple movable rollers 61 to move and retract. At this time, the annular rubber workpiece can be installed or removed. After releasing the pressure plate 11, the elastic force of the spring 14 drives the incomplete rack 10 to reset, thereby driving the transmission gear 9 to reverse and reset, and finally drives the movable roller 61 to reverse and reset;

[0048] By setting the incomplete rack 1, the pressure plate 11, the spring 14 and the transmission gear 9, when the pressure plate 11 is pressed, the movable roller 61 can be controlled to shrink briefly and then reset, which is convenient for quickly installing or removing the annular rubber workpiece and is conducive to fast loading and unloading.

[0049] Example 6, see Figure 7 , different from the above embodiment, the movable roller 61 includes a circular shell, and annular flanges are fixed to the edges of the two outer side walls of the circular shell.

[0050] The annular flange limits the edges of the annular rubber workpiece on both sides, and blocks the annular rubber workpiece from moving sideways when the annular rubber workpiece rotates, thereby preventing the annular rubber workpiece from falling off.

[0051] Embodiment 7 is a feeding method for processing an annular rubber workpiece. The feeding method for processing an annular rubber workpiece uses a suspension conveying device in the above embodiment.

[0052] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
