[0002] With the rapid development of e-commerce, the logistics industry has also grown rapidly. In the logistics industry, the balance wheel sorter is widely used in various application scenarios due to its advantages such as high sorting efficiency, large load and fast response. In addition, in actual on-site application scenarios, in order to meet the customer's needs for the layout of the sorting port and the maximum utilization of the site with the greatest efficiency, multiple balance wheel sorters will be arranged in series on the same main line or branch line.
[0003] However, in order to fully divert the parcel to the sorting port, the roller conveyor sorting surface of the oscillating wheel sorter is usually higher than the conveying surface of the rear conveyor line by a certain distance. As a result, when the unsorted parcel passes through the frequently started and stopped oscillating wheel sorter, the parcel may stay half on the oscillating wheel sorter and half on the rear conveyor line. When the line is started again, due to the unstable center of gravity of the parcel and the height difference between the oscillating wheel sorter and the conveyor line, the parcel posture is easily skewed, causing the subsequent sorting failure and package jam of the oscillating wheel sorter.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.
[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0036] In addition, in the description of the present invention, unless otherwise specified, “plurality” means two or more.
[0037] See also Figures 1 to 3 The present embodiment provides a cam rotary lifting steering sorting mechanism, comprising a floating seat 1, a base 2 and a servo motor 3. A plurality of swing wheel units 11 with synchronously adjusted swing angles are installed on the top of the floating seat 1, and a roller assembly 12 is installed on the bottom. The floating seat 1 can be lifted and lowered on the base 2. A cam disc 21 capable of axial rotation is installed on the base 2. The top of the cam disc 21 is provided with an annular edge whose height gradually changes along the circumferential direction. The lifting roller 121 on the roller assembly 12 abuts against the annular edge at the top of the cam disc 21. The servo motor 3 is arranged on the base 2 and is axially connected to the cam disc 21.
[0038] See also Figures 1 to 3 The cam rotary lifting steering sorting mechanism of this embodiment can drive the cam plate 21 on the base 2 to rotate axially through the servo motor 3, and then drive the roller assembly 12 to move up and down through the annular edge on the top of the cam plate 21. Because the roller assembly 12 is arranged on the floating seat 1, the floating seat 1 can move up and down relative to the base 2. Therefore, when the package is transported straight, the conveying surface of the pendulum unit 11 can be flush with the conveying surface of the front and rear conveying lines; when the package is in the sorting state, the pendulum unit 11 is lifted to the same height as the rear belt conveyor of the bevel machine at the sorting port, and the conveying surface of the pendulum unit 11 is higher than the conveying surface of the rear conveyor line.
[0039] Obviously, the cam rotary lifting steering sorting mechanism of this embodiment can enhance the stability of conveying and sorting, and avoid package skewness causing package blockage and line stoppage.
[0040] Preferably, see Figure 1 and Figure 2 Four guide column bearings 22 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 22, so that the upper floating seat 1 is installed on the base 2 with upper and lower limits.
[0041] Preferably, see Figures 1 to 3 A swing arm rod 31 is fixed on the driving end of the servo motor 3, and multiple balance wheel units 11 are 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 connecting rod 32, and the other end of the connecting rod 32 is hinged to the free end of the swing arm rod 31.
[0042] When the driving end of the servo motor 3 rotates forward and backward, it will drive the cam plate 21 to rotate axially while also driving the swing arm rod 31 to rotate, and then drive the swing frame 13 to move left and right through the connecting rod 32, thereby realizing the synchronous adjustment of the swing angles of the multiple balance wheel units 11 on the top of the floating seat 1, and the cam plate 21 drives the lifting and lowering movements of the multiple balance wheel units 11 to be carried out synchronously.
[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 and Figure 2 The swing frame 13 includes a connecting plate 131, a connecting support plate 132 and a follower plate 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 connecting plate 131. Multiple connecting plates 131 are arranged in parallel and spaced apart and are vertically connected to a connecting support plate 132 at the bottom. Multiple connecting support plates 132 are connected and fixed through a follower plate 133. The follower plate 133 is hinged to one end of the connecting rod 32. Multiple connecting plates 131 are connected through the follower plate 133 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 2The roller assembly 12 includes a roller seat 122 and a lifting roller 121. The roller seat 122 is fixed at the bottom of the floating seat 1. The two lifting rollers 121 are rotatably arranged at intervals on the roller seat 122 and respectively abut against the annular edge of the top of the cam plate 21 to ensure that the contact between the lifting roller 121 on the roller assembly 12 and the annular edge of the top of the cam plate 21 is more stable, so as to ensure that the floating seat 1 is more stably lifted and lowered relative to the base 2.
[0046] Preferably, see Figure 4 The annular edge at the top of the cam disc 21 is provided with a horizontal ring segment 211, a concave arc ring segment 212, a horizontal ring segment 211 and a convex ring segment 213 in sequence within each semicircular range. The edge surface height on the horizontal ring segment 211 is kept consistent, and the edge surface height on the concave arc ring segment 212 gradually decreases from both sides to the middle part, and the radius of the concave arc ring segment 212 is larger than the radius of the lifting roller 121. The edge surface height on the convex ring segment 213 is kept consistent and higher than the edge surface height on the horizontal ring segment 211.
[0047] Therefore, the contact point between the lifting roller 121 and the cam disc 21 has the highest point when it is located at the horizontal ring segment 211 and the lowest point when it is located at the lowest point of the inner concave arc ring segment 212. With the axial rotation of the cam disc 21, the contact point between the lifting roller 121 and the cam disc 21 is constantly switched between high and low points, corresponding to the rise and fall of the upper floating seat 1. At the same time, the setting of the raised ring segment 213 on the cam disc 21 can limit the lifting roller 121, preventing one lifting roller 121 from moving to the semicircular range where the other lifting roller 121 should abut.
[0048] This embodiment also provides a swing wheel sorting machine, which adopts the above-mentioned cam rotating top-lifting steering sorting mechanism. By adopting the above-mentioned cam rotating top-lifting steering sorting mechanism, the swing wheel sorting machine of this embodiment has two levels of height 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.
