Description

Technical Field

[0001] The present application relates to the field of conveying equipment, and in particular to a roller conveying device. Background Art

[0002] In the modern workpiece production process, it is usually necessary to use a variety of equipment such as conveying equipment, production equipment, and transfer equipment to form a production line. The conveying equipment plays the role of transporting materials, delivering and transferring materials between various equipment, so as to improve production efficiency and shorten production intervals. At present, for workpieces with flat bottoms, especially box-type workpieces, roller conveyors are mostly used. They have the advantages of simple structure and easy assembly. However, during use, they involve diverting different types of workpieces or products of different qualities so that they can be transported to pre-set locations, or used to relieve congestion in the conveying device, optimize the production line layout, and reduce material transportation pressure. Current roller conveyors mostly use electric push rods to divert workpieces, which are directly pushed to another roller conveyor to complete the diversion. However, since the machine does not stop during pushing, the box still has inertia during pushing, resulting in the state and direction of the box pushed to the sub-roller conveyor being difficult to control, which makes it difficult to control the subsequent next processing. Therefore, it often takes a lot of time to debug the production line or manually adjust the box shape. The pushing method also causes the box to rub vertically on the roller, affecting its pass rate.

Obviously, the embodiments described 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.

[0023] See also Figures 1 to 8 As shown, the utility model provides the following technical solutions: a roller conveying device, comprising a main roller conveyor 1, a diversion roller conveyor 2 and a diversion mechanism 3 for positioning and diverting the conveyed box; the main roller conveyor 1 is arranged on the ground, the diversion roller conveyor 2 is vertically arranged on the side of the main roller conveyor 1, the lower end of the diversion mechanism 3 is bolted to the ground, the diversion mechanism 3 is arranged at the lower part of the main roller conveyor 1, and a lifting component 4, a rolling component 5 and a positioning component 6 are arranged in the diversion mechanism 3, the lower end of the lifting component 4 is bolted to the ground, the rolling component 5 and the positioning component 6 are both arranged at the upper end of the lifting component 4, the main roller conveyor 1 conveys the box, the lifting component 4 lifts the rolling component 5 and the positioning component 6, the rolling component 5 lifts the box and conveys the box to the diversion roller conveyor 2 by rotation, and the positioning component 6 positions the box by pushing on both sides.

[0024] As another example, Figures 1 to 3As shown, the main roller conveyor 1 and the diversion roller conveyor 2 both include symmetrically arranged legs 11, side plates 12, and arrays of evenly arranged rollers 13. The lower ends of the legs 11 are in contact with the ground, and the upper ends of the legs 11 are bolted to the side plates 12. Both ends of the rollers 13 are rotatably connected to the side plates 12. A sprocket is provided at one end of the roller 13, and the arrays of sprockets are connected by chain transmission. A driving motor is provided at the lower part of the side plate 12. The driving motor drives the sprocket to rotate so that the rollers 13 rotate synchronously. The synchronous rotation of the rollers 13 drives the box thereon to move, thereby achieving the purpose of transporting the box.

[0025] As another embodiment, Figures 4 to 6 As shown, the lifting assembly 4 includes a support plate 41, a hydraulic lifter 42, and a base plate 43. The lower end of the support plate 41 is bolted to the ground, the hydraulic lifter 42 is arranged on the upper part of the support plate 41, and the lower end of the base plate 43 is bolted to the output end of the hydraulic lifter 42. The hydraulic lifter 42 is electrically powered, and the lifting assembly 4 is electrically connected to the rolling assembly 5 and the positioning assembly 6. The device is also provided with a controller, which can control the lifting height of the hydraulic lifter 42 and the rolling speed of the rolling assembly 5. The output end of the hydraulic lifter 42 is provided with an array to improve the stability of the base plate 43. When the box is transported to a position perpendicular to the diversion roller conveyor 2, the hydraulic lifter 42 pushes the base plate 43 upward, thereby driving the rolling assembly 5 and the positioning assembly 6 to rise and pass through the gap between the rollers 13. The box is intercepted and positioned by the positioning assembly 6, and then the box is rolled and transported to the diversion roller conveyor 2 by the rolling assembly 5, completing the diversion of the box.

[0026] See also Figure 4 as well as Figure 5 The rolling assembly 5 includes a first support rod 51, a transverse support rod 52, a roller 53, and a transmission module 54. The lower end of the first support rod 51 is in transmission connection with the upper end of the base plate 43. Four groups of first support rods 51 are provided, and two groups of first support rods 51 are connected by the transverse support rod 52. The transmission module 54 is located within the transverse support rod 52, and the roller 53 is rotationally connected to the upper end of the first support rod 51. After the lifting assembly 4 pushes the rolling assembly 5 above the roller 13, the positioning assembly 6 intercepts and positions the box. At this time, the group of rollers 53 lifts the box, preparing for the diversion operation.

[0027] See also Figure 5The transmission module 54 includes a double-headed motor 541, a rotating rod 542, a driving wheel 543, and a transmission belt 544. The double-headed motor 541 is bolted to the inner wall of the horizontal support rod 52. Two sets of rotating rods 542 are plugged into the output ends of the double-headed motor 541 on both sides. The rotating rods 542 extend into the interior of the first support rod 51. The driving wheel 543 is plugged into the end of the rotating rod 542 away from the double-headed motor 541. The roller 53 is connected to the driving wheel 543 through the transmission belt 544. The output ends of the double-headed motor 541 rotate in the same direction. After the roller 53 lifts the box, the double-headed motor 541 is started, driving the rotating rods 542 on both sides to rotate, so that the rotating rods 542 drive the driving wheel 543 to rotate, and then the driving wheel 543 drives the roller 53 to rotate through the transmission belt 544, so that the roller 53 conveys the box to the diverter roller conveyor 2 through rotation.

[0028] As another example, Figure 5 and Figure 7 as well as Figure 8 As shown, the positioning assembly 6 includes a second support rod 61, a blocking plate 62, a positioning plate 63, and a pushing module 64. The lower end of the second support rod 61 is bolted to the upper end of the bottom plate 43. The second support rod 61 is provided with four groups. The lower end of the blocking plate 62 is plugged into the upper end of the second support rod 61. One end of the pushing module 64 is rotatably connected to the inner wall of the blocking plate 62, and the other end of the pushing module 64 is rotatably connected to the positioning plate 63. After the hydraulic lifter 42 lifts the bottom plate 43, it drives the second support rod 61 upward, causing the blocking plate 62 to rise above the roller 13 to intercept the box. During the process of the blocking plate 62 rising, the pushing module 64 pushes the positioning plate 63, so that the protruding positioning plate 63 clamps and positions the box to a certain extent and corrects the box's posture. The positioning plate 63 is made of a material with low friction, such as a velvet material. A wheel structure can also be used instead of the positioning plate 63 to further reduce friction.

[0029] See also Figure 7 The blocking plate 62 has a slot on its side for facilitating the extension of the positioning plate 63, and a slide slot 621 on its rear. The second support rod 61 is disposed on both sides of the first support rod 51. The positioning plate 63 is normally located inside the blocking plate 62. When the blocking plate 62 rises, the positioning plate 63 is driven by the push module 64 to extend from the blocking plate 62 to position the box.

[0030] See also Figure 7The pushing module 64 includes a slider 641, a sliding link 642, a rotating link 643, and a through-link 644. The slider 641 is slidably connected to the blocking plate 62 through the sliding groove 621. One end of the sliding link 642 is rotatably connected to the slider 641, and the other end of the sliding link 642 is rotatably connected to the rear end of the positioning plate 63. One end of the rotating link 643 is rotatably connected to the inner wall of the blocking plate 62, and the other end of the rotating link 643 is rotatably connected to the middle of the sliding link 642. One end of the through-link 644 is plugged into the rear end of the slider 641, and the other end of the through-link 644 is fixedly connected to the support plate 41. When the blocking plate 62 rises, since the through-link 644 is fixed in position and does not move, the slider 641 slides downward along the sliding groove 621 relative to the blocking plate 62, causing the sliding link 642 to move and rotate, thereby driving the positioning plate 63 to protrude from the blocking plate 62 to position the box.

[0031] See also Figure 8 The connecting rod 644 includes an inner rod 6441, an outer rod 6442, and a spring 6443. The upper end of the inner rod 6441 is plugged into the rear end of the slider 641, the lower end of the outer rod 6442 is bolted to the support plate 41, the lower end of the spring 6443 is connected to the inner wall of the outer rod 6442, and the upper end of the spring 6443 is connected to the lower end of the inner rod 6441. The inner rod 6441 is slidably arranged inside the outer rod 6442. When the second support rod 61 is not rising, the spring 6443 is compressed, pushing the inner rod 6441 to push the slider 641 against the upper end of the slide groove 621. After the second support rod 61 rises a certain distance, the spring 6443 is normal, and the slider 641 will not continue to rise synchronously. At this time, the slider 641 descends relatively, driving the sliding connecting rod 642 to rotate and push the positioning plate 63 out, thereby preventing the positioning plate 63 from being pushed out too early and contacting the roller shaft.

[0032] Working principle: When in use, the parameters of the diversion mechanism 3 are set in advance according to the box size and box spacing. When the box that needs to be diverted is transported to a position perpendicular to the diversion roller conveyor 2 by the main roller conveyor 1, the support plate 41 lifts the bottom plate 43 through the hydraulic lift, so that the first support rod 51 and the second support rod 61 rise, and the second support rod 61 is higher than the first support rod 51, and first rises above the roller. After rising a distance, the spring 6443 has no elastic force, and the slider 641 moves downward relatively, thereby pushing the sliding link 642 to move, thereby causing the positioning plate 63 to be pushed out, pushing and positioning the box blocked by the blocking plate 62, so that the box shape and position reach the specified position, and then the box is lifted up by the set roller 53, and the transmission module 54 starts to drive the driving wheel 543, thereby driving the roller 53 to rotate, and the box is rolled and transported to the diversion roller conveyor 2, and the lifting component 4 drives the rolling component 5 and the positioning component 6 to move down, waiting for the next diversion.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood 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 present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
