[0031] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0033] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the product of the invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0034] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0035] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" 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 it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. 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 the following examples, unless otherwise specified, Figure 1 The ab direction is the first direction, the cd direction is the second direction, and the first direction and the second direction are perpendicular. Obviously, in other embodiments, the first direction and the second direction can also be at other angles.

[0037] See also Figure 1-Figure 5 The present embodiment provides a balance wheel sorting device for transferring and sorting articles. The O-belt 400 of the balance wheel sorting device is convenient and quick to disassemble and assemble, and has high disassembly and assembly efficiency.

[0038] See also Figure 1-Figure 3 In this embodiment, the balance wheel sorting device includes a frame 100, a plurality of balance wheel modules 200, a plurality of transition wheels 300 and a plurality of O-belts 400; the plurality of balance wheel modules 200 are arranged on the frame 100 at intervals, the plurality of transition wheels 300 are rotatably connected to the frame 100, the plurality of balance wheel modules 200 correspond to the plurality of transition wheels 300 one by one and are transmission-connected through an O-belt 400; in the extension direction of the axis of the transition wheel 300, at least one side of the transition wheel 300 is suspended, so that the O-belt 400 can be directly put on the transition wheel 300 or removed from the transition wheel 300 from the suspended side of the transition wheel 300.

[0039] The balance wheel sorting device provided in this embodiment has a balance wheel module 200 and a corresponding transition wheel 300 connected by an O-belt 400. When the transition wheel 300 rotates, the power is transmitted to the balance wheel module 200 through the O-belt 400, thereby driving the balance wheel module 200 to rotate, and finally realizing the transportation of items on the balance wheel module 200. Figure 3, where A represents the suspended side of the transition wheel. Since at least one side of the transition wheel 300 in the extension direction of its axis is suspended, the suspended side of the transition wheel 300 is not blocked. When disassembling the O-belt 400, the O-belt 400 can be directly removed from the suspended side of the transition wheel 300, and then removed from the corresponding balance wheel module 200; at the same time, when installing a new O-belt 400 on the transition wheel 300, the O-belt 400 can be directly put on the outside of the transition wheel 300 from the suspended side of the transition wheel 300. In the process of disassembling and assembling the O-belt 400, it is not necessary to dismantle other structures connected to the transition wheel 300, thereby greatly reducing the difficulty of disassembly and assembly, shortening the disassembly and assembly time, and improving the efficiency of disassembly and assembly.

[0040] See also Figure 1 In this embodiment, optionally, the frame 100 includes an enclosure 110, a support leg 120 and a balance wheel disc 130. The enclosure 110 can be surrounded by a rectangular structure, that is, the enclosure 110 includes two first plates 111 opposite to each other in the first direction and two second plates 112 opposite to each other in the second direction. The adjacent first plates 111 and second plates 112 are connected, and the first plates 111 and second plates 112 can both be rectangular plates. Among them, the first direction and the second direction are perpendicular. The support leg 120 is connected to the enclosure 110, and the support leg 120 is used to support on the ground. The balance wheel disc 130 is installed on the side of the enclosure 110 away from the support leg 120. The balance wheel disc 130 is provided with the same number of mounting holes 131 as the balance wheel module 200. Each mounting hole 131 corresponds to a balance wheel module 200. The balance wheel disc 130 not only plays the role of positioning the balance wheel module 200, but also plays the role of carrying objects.

[0041] Optionally, the support legs 120 are configured as height-adjustable structures. It should be understood that the number of support legs 120 is set as needed, and can be sufficient to support the enclosure 110 and maintain the balance of the enclosure 110. For example, in this embodiment, the number of support legs 120 is four, and the four support legs 120 are approximately located at the four corners of the enclosure 110.

[0042] See also Figure 3 In this embodiment, optionally, each transition wheel 300 includes a wheel body 310 and a wheel axle 320. The wheel body 310 of the transition wheel 300 is provided with an annular receiving groove for accommodating the O-belt 400. The wheel axle 320 is fixedly connected to the wheel body 310, and the two are coaxially arranged. Moreover, after the wheel body 310 and the wheel axle 320 are assembled, one end of the wheel axle 320 is connected to the wheel body 310, and the other end extends along the end face away from the wheel body 310. The outer peripheral surface of the wheel axle 320 is provided with a first transmission part 330, and the first transmission part 330 can be a gear, a sprocket, a pulley, etc. The first transmission part 330 can be integrally formed with the wheel axle 320, or the two can be processed separately and then assembled into one.

[0043] Optionally, each transition wheel 300 can be provided separately, and at least one side of each transition wheel 300 in the axial direction thereof is suspended. For example, the first end of the axle 320 can be connected to the frame 100, and the second end of the axle 320 is suspended. In this case, the side of the transition wheel 300 corresponding to the second end is suspended, and the O-belt 400 can be disassembled from the side corresponding to the second end of the axle 320.

[0044] In other embodiments, in the extension direction of the axis of the transition wheel 300, adjacent transition wheels 300 form a group, the wheel axles 320 of the two transition wheels 300 in the same group are connected, and the outer sides of the two transition wheels 300 in the same group are both suspended. By arranging the two transition wheels 300 in a group, not only can the outer side of each transition wheel 300 be suspended, but also the two transition wheels 300 in the same group can be symmetrically arranged, with good force and more stable operation.

[0045] Furthermore, the balance wheel sorting device further comprises a mounting member 500, and the mounting member 500 is connected to two opposite first plates 111. In other words, the mounting member 500 extends along the first direction and its two ends are respectively fixed to the two first plates 111. The wheel axles 320 of the two transition wheels 300 of the same group are both connected to the mounting member 500, and the wheel bodies 310 of the two transition wheels 300 of the same group are located on both sides of the mounting member 500 in the second direction.

[0046] It should be understood that the axles 320 of the two transition wheels 300 of the same group are coaxially arranged, and the two axles 320 can be independent of each other and rotatably connected to the mounting parts 500 respectively. Obviously, the two axles 320 can also be formed in one piece. With such a design, when installing the two transition wheels 300 of the same group, the axles 320 can be first inserted into the mounting parts 500, and then the two wheel bodies 310 can be assembled at both ends of the axles 320 for easy disassembly and assembly.

[0047] For example, in this embodiment, two axles 320 of the same group are integrally formed. At the same time, two retaining springs are arranged on the axle 320, and the two retaining springs are located on both sides of the mounting member 500 in the second direction and both abut against the mounting member 500, thereby preventing the axle 320 from sliding relative to the mounting member 500 in its extension direction.

[0048] It should be noted that there are multiple balance wheel modules 200, and the multiple balance wheel modules 200 are arranged in a rectangular array. It is assumed that the multiple balance wheel modules 200 arranged in the first direction are columns, and the multiple balance wheel modules 200 arranged in the second direction are rows. When the angle of the balance wheel module 200 is zero, that is, when the balance wheel module 200 is not adjusted, the rotation axis of the balance wheel module 200 extends along the second direction. In other words, in the initial state, the multiple balance wheel modules 200 transport the objects along the first direction.

[0049] In this embodiment, the mounting member 500 extends along the first direction, and a plurality of transition wheels 300 are arranged on the mounting member 500, and the plurality of transition wheels 300 are arranged at intervals in the extending direction of the mounting member 500, and each transition wheel 300 corresponds to two corresponding balance wheel modules 200. In other words, one mounting member 500 can be installed with transition wheels 300 corresponding to two adjacent columns of balance wheel modules 200, and therefore, the number of mounting members 500 can be determined according to the number of columns of the balance wheel modules 200. When the number of columns of the balance wheel modules 200 is odd, the transition wheels 300 corresponding to one column of the balance wheel modules 200 can be arranged on the single mounting member 500. At the same time, the number of groups of transition wheels 300 on each mounting member 500 can be equal to the number of rows of the balance wheel modules 200.

[0050] It should be noted that the mounting member 500 can be fixed on the two opposite first plates 111 by screws.

[0051] See also Figure 2 and Figure 3 In this embodiment, optionally, the balance wheel sorting device further includes a first driving member 600 and a driving shaft 700. The first driving member 600 may be a motor or a matching structure of a motor and a reducer. The first driving member 600 is disposed on the frame 100 and may be connected to the supporting foot 120 of the frame 100 through the mounting plate 140. The output shaft of the first driving member 600 is transmission-connected to the driving shaft 700 to drive the driving shaft 700 to rotate. The first driving member 600 may be transmission-connected to the driving shaft 700 by means of belt transmission, chain transmission, gear transmission, etc. The driving shaft 700 extends along the second direction, and the transition wheels 300 in the same row are transmission-connected to the same driving shaft 700. Obviously, the number of driving shafts 700 may be set accordingly according to the number of rows of transition wheels 300 (the number of rows of balance wheel modules 200).

[0052] It should be noted that a second transmission part 710 is provided on the drive shaft 700, and the second transmission part 710 can be a gear, a sprocket, a pulley, etc. The second transmission part 710 on the drive shaft 700 cooperates with the first transmission part 330 on the transition wheel 300. In other words, the drive shaft 700 and the transition wheel 300 can be connected by belt drive, chain drive, gear drive, etc.

[0053] In addition, the multiple drive shafts 700 can be driven by a first drive member 600, and the first drive member 600 is connected to a drive shaft 700 among the multiple drive shafts 700. In the first direction, the adjacent drive shafts 700 can be connected by belt drive, chain drive, gear drive, etc. When a first drive member 600 is used to drive a drive shaft 700 to rotate, the remaining drive shafts 700 can also rotate together under the drive of the transmission structure. The rotation of the drive shaft 700 drives the transition wheel 300 to rotate, and finally drives the balance wheel module 200 to rotate through the O-belt 400, so that objects can be transported.

[0054] It should be understood that in other embodiments, each drive shaft 700 can be driven and connected via a first drive member 600 alone.

[0055] See also Figure 4 and Figure 5 In this embodiment, optionally, the balance wheel sorting device also includes a second driving member 800, a swing frame 900 and a transmission mechanism 010. The balance wheel module 200 is installed on the swing frame 900, and the swing frame 900 is movably connected to the frame 100. The second driving member 800 is connected to the swing frame 900 through the transmission mechanism 010, and is used to drive the swing frame 900 to swing. The movement of the swing frame 900 drives the balance wheel module 200 on the swing frame 900 to move, thereby adjusting the direction in which the balance wheel module 200 transmits items.

[0056] Optionally, the transmission mechanism 010 includes a connecting member 011 and a shifting member 012 . The second driving member 800 is connected to the connecting member 011 for driving the connecting member 011 to rotate. The shifting member 012 is connected to the connecting member 011 and is eccentrically arranged with respect to the rotation axis of the connecting member 011 .

[0057] Optionally, a strip hole 910 is provided on the swing frame 900 , and the toggle member 012 is inserted into the strip hole 910 . The toggle member 012 is used to abut against the hole wall of the strip hole 910 to drive the swing frame 900 to swing.

[0058] It should be noted that the second driving member 800 may be a servo motor. In addition, the toggle member 012 may be a cylindrical rod, and the outer peripheral surface of the toggle member 012 abuts against the hole wall of the strip hole 910, and the contact area between the two is small, resulting in less wear.

[0059] Furthermore, a roller may be disposed on the outer surface of the toggle member 012 , and the roller may rotate when in contact with the hole wall of the strip hole 910 , thereby further reducing friction and wear.

[0060] It should be understood that the swinging motion of the swing frame 900 can be driven by one or more drive structures mainly composed of the second drive member 800 and the transmission mechanism 010. For example, in this embodiment, the swing frame 900 is driven by two drive structures, and the two drive mechanisms are respectively located at the positions corresponding to the two second plates 112.

[0061] Optionally, the balance wheel sorting device further includes two auxiliary rollers 020, both of which are rotatably connected to the frame 100 and are located on both sides of the frame 100 in the first direction.

[0062] In the balance wheel sorting equipment provided in this embodiment, each O-belt 400 can be independently disassembled and installed from the corresponding transition wheel 300, and multiple O-belts 400 will not interfere with each other, thereby reducing the steps required for O-belt disassembly and assembly operations. The disassembly and assembly operations of the O-belts 400 are convenient and fast, thereby improving the efficiency of equipment maintenance and overhaul.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
