Description

Technical Field

[0001] This utility model relates to the field of conveying devices, specifically to a conveying positioner device. Background Technology

[0002] Swing wheel sorting machines can perform sorting, merging, and repositioning of items, and are widely used in the express delivery and logistics industry due to their advantages such as high sorting speed and low error rate. The conveyor positioning device is a key structure in the composition of a swing wheel sorting machine. Existing conveyor positioning devices generally include multiple swing wheel units that can convey items and a swinging device that drives the swing wheel units to swing. For example, the swing wheel mechanism, as disclosed in Chinese Invention Patent No. CN113968474B, includes: a connecting plate; a driving mechanism connected to the connecting plate via a first connecting structure, which drives the connecting plate to swing; multiple roller modules, each connected to the connecting plate via a second connecting structure, and arranged along the length of the connecting plate; the multiple roller modules rotate around their own axes as the connecting plate swings. This invention ensures that the roller modules within the same swing wheel mechanism rotate synchronously, maintaining a consistent conveying direction and improving sorting accuracy. The first connecting structure includes a crank, a rotating shaft assembly, and a drive plate; one end of the crank is connected to a drive mechanism, and the other end is connected to the rotating shaft assembly; the drive plate is connected to the connecting plate, and a groove extending along the width direction of the connecting plate is provided in the drive plate; the rotating shaft assembly is movably placed in the groove along the extension direction of the groove.

[0003] However, the existing conveying positioner device has the following problems: the first connecting structure used to connect the drive mechanism and the connecting plate is limited by the slide on the drive plate, thereby driving the connecting plate to swing within a certain range. However, during the swinging process, the rotating shaft assembly and the inner wall of the slide are prone to wear, which can damage the rotating shaft assembly and thus affect the swing of the balance wheel. Utility Model Content

[0004] The technical solution adopted by this utility model to solve its technical problem is: to provide a conveying positioner device, comprising:

[0005] A connecting plate, on which multiple balance wheel mechanisms are rotatably connected, and the connecting plate is provided with rotation holes for the balance wheel mechanisms to pass through;

[0006] A drive motor is provided, the output end of which is connected to a rotating structure. The drive motor drives the balance wheel mechanism to swing through the rotating structure. The rotating structure includes a cam, a rotating shaft, and a connecting frame. The cam is connected to the output end of the drive motor. The rotating shaft and the cam are relatively fixed. The rotating shaft and the connecting frame are rotatably connected. A connecting rod is provided on the connecting frame. Multiple rocker arms corresponding to the balance wheel mechanism are rotatably connected to the connecting rod. The rocker arms and their corresponding balance wheel mechanisms are relatively fixed.

[0007] Furthermore, the balance wheel mechanism includes a fastening assembly, a swing frame, and a balance wheel. The balance wheel is rotatably mounted on the swing frame, and the swing frame is rotatably mounted in a rotating hole via the fastening assembly.

[0008] Furthermore, the fastening assembly includes a connecting bushing, a limiting bolt, and a limiting bushing. The connecting bushing is connected to the swing frame, the limiting bushing is sleeved on the connecting bushing, and the limiting bushing is rotatably disposed in the rotating hole. The limiting bolt is used to fix the connecting bushing to the rocker arm.

[0009] Furthermore, the rocker arm is provided with a spline groove for the connecting bushing to pass through, and the connecting bushing is provided with a protrusion corresponding to the spline groove, the protrusion being confined within the spline groove.

[0010] Furthermore, the limiting bushing is provided with a limiting part, the diameter of which is larger than the diameter of the rotating hole.

[0011] Furthermore, the limiting bushing is located between the swing frame and the rocker arm, and the outer diameter of the limiting bushing is larger than the diameter of the spline groove.

[0012] Furthermore, both the drive motor and the rotating structure are provided with multiple units.

[0013] Furthermore, the rocker arm is also provided with a through hole, and a fastening bolt and a fastening nut are provided in the through hole. The fastening bolt is used to cooperate with the fastening nut to rotate the rocker arm to the connecting rod.

[0014] The beneficial effects of this invention are as follows: Through a multi-stage transmission structure involving a cam, connecting frame, and rocker arm, the balance wheel mechanism is indirectly driven to swing by transmitting power through multiple rotating pairs whose axes of rotation are not on the same straight line. Simultaneously, the swing of the balance wheel mechanism is limited by the rotating holes on the connecting plate, which cooperate with the connecting rod and rocker arm. Compared to the existing technology that uses a groove to limit the rotational shaft assembly, this invention replaces the sliding process with multiple rotational processes, reducing wear caused by sliding friction and avoiding transmission failure due to groove wear, thereby ensuring the stability of the balance wheel mechanism's swing.

Detailed Implementation

[0024] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic aspects of the present utility model, and therefore only shows the components relevant to the present utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] Please refer to Figure 1This utility model provides a conveying and positioning machine device 100, including a connecting plate 10 and a drive motor 20. Multiple swing wheel mechanisms 30 are rotatably connected to the connecting plate 10, and the connecting plate 10 has rotation holes 11 for the swing wheel mechanisms 30 to pass through. Multiple drive motors 20 and rotating structures 40 are also provided. For details, please refer to... Figure 1 In practice, multiple balance wheel mechanisms 30 are divided into multiple groups, and each drive motor 20 drives multiple balance wheel mechanisms 30 in the same group to rotate simultaneously in the same direction. By using multiple drive motors 20, the balance wheel mechanism 30 can be driven to swing in multiple directions or in the same direction, thereby adapting to different swing direction requirements.

[0026] Please refer to Figure 2 , Figure 3 , Figure 4 and Figure 7 The output end of the drive motor 20 is connected to a rotating structure 40. The drive motor 20 drives the balance wheel mechanism 30 to swing through the rotating structure 40. The rotating structure 40 includes a cam 41, a rotating shaft 42, and a connecting frame 43. The cam 41 is connected to the output end of the drive motor 20. The rotating shaft 42 and the cam 41 are relatively fixed. The rotating shaft 42 and the connecting frame 43 are rotatably connected. The connecting frame 43 is provided with a connecting rod 431. Multiple rocker arms 432 corresponding to the balance wheel mechanism 30 are rotatably connected to the connecting rod 431. The rocker arms 432 and their corresponding balance wheel mechanisms 30 are relatively fixed. Specifically, the connecting plate 10 is provided with a carrier 12 for mounting the drive motor 20. The rotation axis of the cam 41 and the rotating shaft 42 are not on the same straight line.

[0027] Through a multi-stage transmission structure involving cam 41, connecting frame 43, and rocker arm 432, the balance wheel mechanism 30 is indirectly driven to swing by transmitting power through multiple rotating pairs whose rotation axes are not on the same straight line. Simultaneously, the swing of the balance wheel mechanism 30 is limited by the rotation hole 11 on the connecting plate 10, which works in conjunction with the connecting rod 431 and rocker arm 432. Compared to the prior art's technique of limiting the rotation shaft assembly through a groove, replacing the sliding process with multiple rotational processes reduces wear caused by sliding friction and avoids transmission failure due to groove wear, thereby ensuring the stability of the balance wheel mechanism 30's swing.

[0028] Please refer to Figure 4 , Figure 5 and Figure 6The balance wheel mechanism 30 includes a fastening assembly, a swing frame 31, and a balance wheel 32. The balance wheel 32 is rotatably mounted on the swing frame 31, and the swing frame 31 is rotatably mounted in the rotation hole 11 via the fastening assembly. The fastening assembly includes a connecting bushing 33, a limiting bolt 34, and a limiting bushing 35. The connecting bushing 33 is connected to the swing frame 31, and the limiting bushing 35 is fitted onto the connecting bushing 33 and rotatably mounted in the rotation hole 11. The limiting bolt 34 is used to fix the connecting bushing 33 to the rocker arm 432. Specifically, the swing frame 31 has a protrusion 311 that passes through the inner hole of the connecting bushing 33.

[0029] Please refer to Figure 6 The rocker arm 432 has a spline groove 4321 for the connecting sleeve 33 to pass through. The connecting sleeve 33 has a protrusion 331 corresponding to the spline groove 4321, and the protrusion 331 is confined within the spline groove 4321. Through the cooperation of the spline groove 4321 and the protrusion 331, the connecting sleeve 33 is circumferentially confined, so that the rocker arm 432 and the connecting sleeve 33 are relatively fixed, thereby fixing the rocker arm 432 and the balance wheel mechanism 30 relatively.

[0030] Please refer to Figure 6 The limiting bushing 35 is provided with a limiting part 351, the diameter of which is larger than the diameter of the rotating hole 11. The limiting part 351 presses against the upper end surface of the connecting plate 10. The limiting bushing 35 is located between the swing frame 31 and the rocker arm 432, and the outer diameter of the limiting bushing 35 is larger than the diameter of the spline groove 4321. The limiting part 351 fixes its position relative to the connecting plate 10. At the same time, the fixed position of the limiting bushing 35 relative to the rocker arm 432 supports the entire balance wheel mechanism 30, making it less likely that the weight of the object on the balance wheel mechanism 30 will cause the rocker arm 432 to descend relative to the connecting plate 10, thus affecting the transmission and improving the transmission efficiency.

[0031] Please refer to Figure 6 The rocker arm 432 is also provided with a through hole 4322, and a fastening bolt 4323 and a fastening nut 4324 are provided in the through hole 4322. The fastening bolt 4323 is used to cooperate with the fastening nut 4324 to rotate the rocker arm 432 to the connecting rod 431.
