[0036] In addition, in the description of the present invention, unless otherwise specified, “plurality” means two or more.
[0037] See also Figure 1 and Figure 3 The present embodiment provides a swing arm connecting rod lifting type steering sorting mechanism, comprising a floating seat 1, a base 2 and a servo motor 3. The top of the floating seat 1 is equipped with a plurality of swing wheel units 11 with synchronously adjusted swing angles, and the bottom is symmetrically spaced with a plurality of rotatable roller guide bearings 12. The floating seat 1 can be lifted and lowered on the base 2. The base 2 is provided with a swing arm connecting rod pair 21 and a guide rail slider pair 22. The two groups of guide rail slider pairs 22 are symmetrically spaced and located on the same straight line. The swing arm connecting rod pair 21 is located in the interval space between the two groups of guide rail slider pairs 22. The two connecting rods 211 on the swing arm connecting rod pair 21 are respectively hinged to a lifting slider 221 on a group of guide rail slider pairs 22. The top of each lifting slider 221 is respectively abutted against the bottom of a roller guide bearing 12. The servo motor 3 is arranged on the base 2 and is axially connected to the swing arm 212 on the swing arm connecting rod pair 21.
[0038] See also Figure 1 and Figure 3 When the swing arm connecting rod lifting type steering sorting mechanism of this embodiment is in use, the swing arm 212 on the swing arm connecting rod pair 21 is controlled by the servo motor 3 to rotate forward and reversely, and the lifting sliders 221 on the two sets of guide rail slider pairs 22 are driven to slide left and right by the two connecting rods 211, thereby lifting or lowering the roller guide bearing 12. Because the roller guide bearing 12 is arranged on the floating seat 1, the lifting and lowering control of the floating seat 1 is realized.
[0039] Obviously, the swing arm connecting rod jacking type steering sorting mechanism of this embodiment can make the conveying surface of the swing wheel unit 11 flush with the conveying surface of the front and rear conveying lines when the package is conveyed in a straight line through the arrangement of the swing arm connecting rod pair 21 and the guide rail slider pair 22; and when the package is in the sorting state, the floating seat 1 can be lifted to keep the conveying surface of the swing wheel unit 11 at the same height as the conveying surface of the belt conveyor behind the bevel machine at the sorting port, and higher than the conveying surface of the rear conveyor line, thereby enhancing the stability of conveying and sorting, and avoiding blockage and line stoppage caused by skewed packages.
[0040] Preferably, see Figure 1 and Figure 3 Four guide column bearings 23 are arranged at rectangular intervals on the base 2, and the floating seat 1 is connected to the base 2 through the four guide column bearings 23, so that the upper floating seat 1 is installed on the base 2 with upper and lower limits.
[0041] Preferably, see Figure 1 , Figure 2 and Figure 4 Multiple balance wheel units 11 can be rotatably hinged at intervals on the top of the floating seat 1, and the same side ends of all the balance wheel units 11 are hinged to the swing frame 13. The bottom of the swing frame 13 is hinged to one end of the steering link 24, and the other end of the steering link 24 is hinged to the swing arm 212.
[0042] When the servo motor 3 drives the swing arm 212 on the swing arm connecting rod pair 21 to rotate forward and reverse, the swing arm 212 will also drive the steering connecting rod 24 to swing left and right together with the two connecting rods 211, and then drive all the balance wheel units 11 on the floating seat 1 to swing at the same angle synchronously through the swing frame 13, so that the lifting and swinging of the balance wheel unit 11 can be controlled synchronously by the servo motor 3.
[0043] Preferably, see Figure 2 The swing unit 11 includes an articulated frame 111 and a roller 112. The articulated frame 111 is rotatably hinged on the top of the floating seat 1. One side end of the articulated frame 111 is hinged to the swing frame 13. The roller 112 is rotatably hinged on the articulated frame 111. When it is necessary to control the swing unit 111 to transport a package, the electronically controlled roller 112 can be rotated relative to the articulated frame 111 to achieve this.
[0044] Preferably, see Figure 1 , Figure 2 and Figure 4 The swing frame 13 includes a connecting plate 131, a connecting rod vertical plate 132 and a swing connecting rod 133. Multiple balance wheel units 11 are arranged in parallel and spaced apart in multiple rows on the floating seat 1. The same side end of each row of balance wheel units 11 is hinged to the same swing connecting rod 133. Multiple swing connecting rods 133 are arranged in parallel and spaced apart and are vertically connected to a connecting rod vertical plate 132 at the bottom. Multiple connecting rod vertical plates 132 are connected and fixed by a connecting plate 131, and the connecting plate 131 is hinged to one end of the steering connecting rod 24. Multiple swing connecting rods 133 are connected by the connecting plate 131 to form a parallelogram structure, which is conducive to ensuring the stability of the steering and swinging of multiple rows of balance wheel units 11 on the floating seat 1.
[0045] Preferably, see Figure 2 and Figure 3 The servo motor 3 is arranged at the bottom of the base 2, and the driving end of the servo motor 3 passes through the top of the base 2 and is connected and fixed to the middle part of the swing arm 212. The two ends of the swing arm 212 are respectively hinged to a connecting rod 211, and one end of the steering connecting rod 24 is hinged to one end of the swing arm 212. When the rotating shaft of the servo motor 3 rotates left and right, it drives the swing arm 212 to rotate left and right, and then drives the lifting slider 221 on the guide slider pair 22 to slide left and right through the connecting rods 211 at both ends of the swing arm 212, and drives the swing frame 13 to move left and right through the steering connecting rod 24 at one end of the swing arm 212.
[0046] Preferably, see Figure 3 The guide rail and slider pair 22 includes a guide rail 222 and a slider 223. A linear slide is provided on the guide rail 222. The slider 223 can be freely slidably arranged in the linear slide. The lifting slider 221 is installed on the top of the slider 223, and the top of the lifting slider 221 is a concave arc surface that gradually sinks from both sides to the middle, and the radius of the concave arc surface is greater than the radius of the roller guide bearing 12.
[0047] Obviously, the specific state of the top of the lifting slider 221 abutting against the bottom of the roller guide bearing 12 is that the concave arc surface at the top of the lifting slider 221 is tangent to the outer circumferential surface of the roller guide bearing 12. When the lifting slider 221 moves left and right along with the slider 223 on the guide rail 222, the height of the contact portion between the lifting slider 221 and the roller guide bearing 12 changes from high to low or from low to high. When the contact portion is at the highest position of the concave arc surface, the balance wheel unit 11 is flush with the docking surface of the sorting port; when the contact portion is at the lowest position of the concave arc surface, the balance wheel unit 11 is flush with the conveying surface of the front and rear conveying lines.
[0048] This embodiment also provides a swing wheel sorting machine, which adopts the above swing arm connecting rod lifting steering sorting mechanism. Due to the adoption of the above swing arm connecting rod lifting steering sorting mechanism, the swing wheel sorting machine of this embodiment can achieve different horizontal height adjustments in the two states of conveying and sorting, making the conveying and sorting of packages more stable, ensuring higher sorting accuracy and the ability to cope with complex environments.
[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
