[0029] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0030] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.
[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0032] Reference Figures 1 to 4 This utility model discloses a roller conveyor device, including a mounting frame 100, multiple conveying rollers 200, and two cover plates 300. Support portions 110 are provided on both the left and right sides of the mounting frame 100. The support portions 110 are in the shape of retaining walls, with their length direction parallel to the front-back direction, and the two support portions 110 are parallel to each other. The mounting frame 100 is plate-shaped.
[0033] Both support portions 110 have a first welding rib 111 on their upper surface. The cross-section of the first welding rib 111 is triangular, and the length direction of the first welding rib 111 is parallel to the front-back direction. Both support portions 110 have multiple limiting grooves 112 distributed along the front-back direction. The limiting grooves 112 are formed on the upper surface of the support portion 110, and the slots of the limiting grooves 112 penetrate through the left and right sides of the support portion 110. The limiting grooves 112 on the two support portions 110 are arranged one-to-one in the left-right direction. Both support portions 110 have multiple fasteners 113 distributed along the front-back direction.
[0034] The number of conveying rollers 200 is half the number of limiting grooves 112. One conveying roller 200 is matched with two limiting grooves 112. The two ends of the conveying roller 200 are respectively provided in two left and right distributed limiting grooves 112. The groove wall of the limiting groove 112 supports and limits the conveying roller 200, and the conveying roller 200 can rotate on the two support parts 110. The length direction of the conveying roller 200 is parallel to the left and right direction, and multiple conveying rollers 200 are distributed along the front and back direction.
[0035] Both cover plates, with a length of 300mm, are parallel to the front-to-back direction, as shown in the reference. Figure 4 and Figure 5Both cover plates 300 are provided with buckle grooves 310, and buckle parts 113 are used to buckle on buckle grooves 310 so that the two cover plates 300 are respectively positioned and engaged with the two support parts 110. The two cover plates 300 are respectively connected to the two support parts 110 through the first welded ribs 111 on the two support parts 110. The two cover plates 300 are used to limit the two ends of the conveying roller 200 to the limiting grooves 112 on the two support parts 110 respectively.
[0036] When assembling the roller conveyor, first place multiple conveying rollers 200 in the limiting groove 112 of the support part 110, and then fasten the cover plate 300 onto the mounting frame 100. At this time, the fastening part 113 fastens onto the fastening groove 310, so that the cover plate 300 and the mounting frame 100 are relatively fixed. Then the ultrasonic welding equipment can be started. The ultrasonic welding equipment connects the cover plate 300 and the mounting frame 100 together through the first welding rib 111.
[0037] The two cover plates 300 serve to limit the multiple conveyor rollers 200 on the mounting frame 100. The first welded rib 111 ensures the firmness of the connection between the cover plate 300 and the mounting frame 100. The highest area of the outer surface of the conveyor roller 200 is higher than the upper surface of the two cover plates 300, allowing the conveyor roller 200 to rotate on the mounting frame 100, thus enabling it to support and transport goods, workpieces, packages, and other items.
[0038] The buckle 113 fastens onto the buckle groove 310, achieving pre-fixation between the cover plate 300 and the mounting bracket 100. No specific clamps are needed to pre-fix the cover plate 300 and the mounting bracket 100 relative to each other, which can also ensure the connection accuracy between the cover plate 300 and the mounting bracket 100. Even if the cover plate 300 and the mounting bracket 100 are subjected to vibration during movement, the cover plate 300 and the mounting bracket 100 can still remain relatively fixed, ensuring the structural dimensional accuracy and processing quality of the roller conveyor.
[0039] It should be understood that the length direction of the mounting bracket 100 and the two support parts 110 are parallel to the front-back direction. The two support parts 110 are distributed on the left and right sides of the mounting bracket 100. The area between the two support parts 110 is the inner side. The left side of the support part 110 on the left side of the mounting bracket 100 is the outer side, and the right side of the support part 110 on the right side of the mounting bracket 100 is also the outer side.
[0040] Reference Figure 4 In some embodiments, the mounting bracket 100 is provided with positioning grooves 120 on the outer side of both support portions 110. That is, the mounting bracket 100 is provided with positioning grooves 120 in the area to the left of the corresponding left support portion 110, and the mounting bracket 100 is also provided with positioning grooves 120 in the area to the right of the corresponding right support portion 110.
[0041] Reference Figure 1 , Figure 4 and Figure 5 The cover plate 300 includes a positioning part 320 and a limiting part 330. The length direction of both the positioning part 320 and the limiting part 330 is parallel to the front-rear direction. The positioning part 320 and the limiting part 330 are connected, and the included angle between the positioning part 320 and the limiting part 330 is close to a right angle. The positioning part 320 is inserted into the positioning groove 120. The cooperation between the positioning part 320 and the positioning groove 120 positions the entire cover plate 300 on the mounting bracket 100, thereby allowing the limiting part 330 to cover the limiting groove 112. The limiting part 330 blocks the end of the conveying roller 200 in the limiting groove 112, preventing the end of the conveying roller 200 from moving downwards and upwards to disengage from the limiting groove 112.
[0042] In some embodiments, when the cover plate 300 needs to be assembled on the mounting bracket 100, the cover plate 300 moves from top to bottom, and the width of the positioning groove 120 and the positioning part 320 gradually decreases from top to bottom, so that the positioning part 320 can be aligned with the positioning groove 120 and inserted into the positioning groove 120. The side wall of the positioning groove 120 can clamp the positioning part 320, further improving the positional accuracy and connection firmness of the assembled cover plate 300.
[0043] Reference Figure 4 and Figure 5 In some embodiments, the bottom of the positioning groove 120 or the lower end face of the positioning part 320 is provided with a second welding rib 321. The ultrasonic device connects the bottom of the positioning groove 120 and the lower end face of the positioning part 320 together through the second welding rib 321, thereby improving the firmness and reliability of the connection between the cover plate 300 and the mounting bracket 100.
[0044] Reference Figure 2 and Figure 6 In some embodiments, the fastener 113 is provided on the outer side of the support portion 110, that is, the fastener 113 is provided on the left side of the support portion 110 on the left side and the fastener 113 is provided on the right side of the support portion 110 on the right side. The fastener groove 310 is provided on the inner side of the positioning portion 320, that is, the fastener groove 310 is provided on the right side of the positioning portion 320 on the left side and the fastener groove 310 is provided on the left side of the positioning portion 320 on the right side. The fastener 113 on the support portion 110 on the left side cooperates with the fastener groove 310 on the positioning portion 320 on the left side, and the fastener 113 on the support portion 110 on the right side cooperates with the fastener groove 310 on the positioning portion 320 on the right side.
[0045] Two positioning parts 320 are located on the outside of the two support parts 110 respectively, and two limiting parts 330 are respectively covered on the limiting grooves 112 on the two support parts 110, and two limiting parts 330 are respectively covered on the two ends of the conveying roller 200. In addition to limiting the conveying roller 200 on the mounting frame 100, the cover plate 300 also protects the ends of the conveying roller 200 and the connection structure between the conveying roller 200 and the mounting frame 100, ensuring that the conveying roller 200 can rotate smoothly and extend its service life.
[0046] Reference Figure 5 It is understood that the opening of the groove 310 faces horizontally and the groove 310 has a lower inner wall. When the cover plate 300 needs to be fastened onto the mounting bracket 100, the fastening part 113 extends into the groove 310 to abut against the lower inner wall of the groove 310, thereby pressing the cover plate 300 onto the mounting bracket 100.
[0047] The highest region of the outer surface of the conveyor roller 200 is higher than the upper surface of the limiting part 330, so that the highest region of the outer surface of the conveyor roller 200 supports the goods and avoids interference between the goods and the limiting part 330.
[0048] Reference Figure 1 , Figure 2 , Figure 4 and Figure 6 In some embodiments, the outer side of the cover plate 300 is provided with a plurality of first limiting blocks 340 distributed in the front-back direction, and the outer side of the mounting bracket 100 is provided with a plurality of second limiting blocks 130 distributed in the front-back direction. The first limiting blocks 340 and the second limiting blocks 130 are staggered in the front-back and up-down directions.
[0049] When two roller conveyors are arranged side by side, the first limiting block 340 of one roller conveyor abuts against the outer side of the cover plate 300 of the other roller conveyor, and the second limiting block 130 of one roller conveyor abuts against the outer side of the mounting frame 100 of the other roller conveyor. The first limiting block 340 and the second limiting block 130 define the gap between the main bodies of the two roller conveyors. In this embodiment, the thickness of the first limiting block 340 and the second limiting block 130 in the left-right direction is 0.6 mm.
[0050] Specifically, a first limiting block 340 on one cover plate 300 can abut against the outer side of another cover plate 300, and the first limiting block 340 on one cover plate 300 is located between two first limiting blocks 340 on another cover plate 300; a second limiting block 130 on one mounting bracket 100 can abut against the outer side of another mounting bracket 100, and the second limiting block 130 on one mounting bracket 100 is located between two second limiting blocks 130 on another mounting bracket 100.
[0051] Reference Figure 3 and Figure 4 Roller conveyors are typically used in combination with existing roller conveyors to form storage devices such as shelves or conveying equipment for transporting goods. Multiple roller conveyors can also be combined on storage devices or conveying equipment. Existing roller conveyors typically have aluminum profiles 400 on both sides. These aluminum profiles 400 are I-shaped and have two horizontally oriented clearance grooves with opposite orientations. To minimize the footprint of the storage device or conveying equipment, a first limiting block 340 and a second limiting block 130 can simultaneously extend into the clearance grooves of the aluminum profile 400. The opposing surfaces of the first limiting block 340 and the second limiting block 130 abut against the upper and lower inner walls of the clearance grooves, respectively. This means that roller conveyors can typically be used in conjunction with existing roller conveyors, improving their versatility and reducing the cost of storage devices or conveying equipment.
[0052] Different goods have different sizes, and partitions are usually used to separate them in order to arrange them in an orderly manner. In some embodiments, the mounting frame 100 has multiple insertion holes 140 distributed in the left-right direction at both the front and rear ends. The insertion holes 140 at the front end of the mounting frame 100 and the insertion holes 140 at the rear end of the mounting frame 100 are arranged one-to-one in the front-back direction. The front and rear ends of the partition are inserted into the insertion holes 140 at the front end and the insertion holes 140 at the rear end of the mounting frame 100, respectively, thereby fixing the partition to the mounting frame 100.
[0053] The mounting rack 100 is typically connected to a support device such as a shelf via a support rail, which facilitates the connection between the mounting rack 100 and the support device. In some embodiments, the mounting rack 100 has locking slots 150 at both its front and rear ends for connecting to the support rail.
[0054] Reference Figure 6 In some embodiments, the bottom of the limiting groove 112 is provided with a protrusion 160, which is used to support the conveying roller 200. The length direction of the protrusion 160 is parallel to the front-back direction. The area of the upper surface of the protrusion 160 is smaller than the area of the bottom of the limiting groove 112. The groove wall of the limiting groove 112 abuts against the conveying roller 200 through the protrusion 160, which can reduce the contact area with the conveying roller 200.
[0055] In some embodiments, the mounting bracket 100 has a perforated structure 170 in the area between the two support portions 110. The perforated structure 170 can reduce the material used and the weight of the mounting bracket 100. The perforated structure 170 can be a circular or polygonal through hole.
[0056] The mounting bracket 100 has a reinforcing rib 180 in the area between the two support parts 110. The two support parts 110 are connected by the reinforcing rib 180, and the reinforcing rib 180 can enhance the structural strength of the mounting bracket 100. The reinforcing rib 180 is plate-shaped.
[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0058] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
