Description

TECHNICAL FIELD

[0001] The utility model relates to conveying line equipment technical field especially relates to a kind of separate drive mechanism for accumulation and release type conveying line. BACKGROUND

[0002] In automobile welding or other production workshop, accumulation and release type conveying line equipment is widely applied to the conveying of workpiece.The equipment usually includes trolley, drive wheel, driven wheel, stopping mechanism and tensioner and other key components, and the trolley is driven by motor to run along conveying line in a loop, and the stopping mechanism is used to ensure the accurate parking of tray at specified position.However, the existing accumulation and release type conveying line exposes some significant limitations in actual use, especially in the accessibility of manual loading and the load capacity of bending.

[0003] Firstly, the design of traditional stopping mechanism has great limitations in manual operation of loading.For example, the Chinese utility model patent document CN203699238U discloses an accumulation and release type conveying line device, please refer to its attached Figure 2 Since the parking position of tray is usually far away from the operator, it is difficult to approach when loading manually, which leads to inconvenient operation and reduces work efficiency.In addition, when the tray passes through the bending, its overturning action completely depends on the motor of drive wheel.However, the motor of drive wheel needs to undertake the running task of the whole conveying line, so the power distribution is limited.When the load of tray is heavy, the output capacity of motor cannot meet the overturning requirement, which limits the load capacity and cannot meet the conveying requirement under complex working conditions, limiting the application of equipment in heavy load environment. UTILITY MODEL CONTENT

[0004] The utility model aims at providing a separate drive mechanism for accumulation and release type conveying line to solve the technical problem that drive wheel cannot undertake the overturning function of tray alone.

[0005] To achieve the above-mentioned purpose, the utility model provides a separate drive mechanism for accumulation and release type conveying line, which comprises a rotating shaft, bearing structure is installed on both ends of the rotating shaft for supporting the rotating shaft and reducing its rotating friction, characterized in that, overbending disc is installed on the inner side close to the bearing structure, motor is installed on one end of the rotating shaft, drive wheel is installed on the middle part of the rotating shaft for driving chain to drive conveying trolley, and middle bearing is arranged between the drive wheel and the rotating shaft.

[0006] The separate drive mechanism for accumulation and release type conveying line provided by the utility model has the following advantages:

[0007] The middle bearing is arranged between the driving wheel and the rotating shaft, so that the driving wheel can rotate freely by the chain driven by other driving wheels when the motor stops running, thereby realizing continuous operation and flexible regulation and control of the conveying trolley; the independent control of the motor can accurately adjust the parking position of the tray, improves the manual accessibility of the loading position, and can be used for individually turning over the tray with load over the bend without affecting the normal bending of other conveying trays, so that the operator can be closer to the tray to complete the loading operation, improves the production efficiency and the convenience of human-computer interaction; and the driving mechanism effectively solves the technical problem that the traditional driving wheel cannot independently bear the tray overturning function after design optimization.

[0014] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the utility model is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the utility model.

[0015] Referring to Figure 1 , one end of the conveying line is provided with a loading position, and the other end is provided with a taking position.

[0016] Referring to Figure 2 , the loading position is provided with a head wheel 7, and the taking position is provided with a tail wheel 8,

[0017] Referring to Figure 3The utility model provides a kind of separation type driving mechanism for accumulation and storage type conveying line, including pivot 5, the both ends of pivot 5 are respectively equipped with bearing structure for supporting pivot 5 and reducing its rotating friction, ensure the smooth operation of pivot. Overbend disc 9 is installed near the inner side of bearing structure, motor 4 is installed in one end of pivot 5, and driving wheel 2 for driving chain to drive conveying trolley is installed in the middle part of pivot, tray 6 for supporting workpiece is provided on conveying trolley, and middle bearing 3 is provided between driving wheel 2 and pivot.

[0018] The utility model is optimized on the basis of traditional driving wheel, mainly increase middle bearing 3, so that when the motor 4 connected to driving wheel stops running, the driving wheel can be driven by other traditional driving wheel through chain and rotate freely, to realize more flexible conveying control. When conveying trolley reaches target position, trolley will be adjusted to appropriate angle by pin 1, and then motor 4 stops running, to ensure that tray is accurately stopped at predetermined position, to provide convenience for manual or automatic equipment loading operation. This design effectively improves the positioning accuracy of conveying process, especially suitable for scenes needing frequent stop or angle adjustment.

[0019] Since separation type driving wheel is used for overturning tray alone without driving chain, compared with traditional driving wheel design, the novel separation type driving mechanism significantly improves functionality and load capacity by improving transmission structure.

[0020] Compared with traditional driving wheel, motor is used for driving the whole equipment, and needs to drive chain, but the new mechanism can overturn tray with all torque, and can overturn larger trolley load; motor is controlled alone, so that tray can be stopped in overbend area, and loading man-machine accessibility is better.

[0021] In addition, since separation type driving wheel is used for tray overturning alone without participating in chain driving, its motion state is more independent, and power output is more concentrated, so that higher torque demand can be withstood, and the efficiency and adaptability of the whole equipment are improved.

[0022] The individual control mode of motor provides higher flexibility for equipment. When conveying trolley reaches overbend area, the mechanism can make tray stay in suitable position by accurately controlling motor action, not only effectively improves the working efficiency of equipment, but also significantly improves the accessibility of loading operation, especially in complex working conditions, can provide more ideal working space for operator or mechanical arm. After the optimization of overall structure design, the driving mechanism not only guarantees rich functions, but also simplifies the mechanical complexity of equipment, reduces maintenance cost, provides stronger load capacity, higher operation efficiency and better user experience for automatic conveying system.

[0023] The separation type driving mechanism for the accumulation and storage type conveying line has the following advantages.

[0024] The driving wheel can independently undertake the turnover function of the tray, and is not dependent on the motor driving of the driving chain, so that the turnover of a larger load is realized when passing the bend. Meanwhile, the optimized stopping mechanism can more flexibly adjust the parking position of the tray, and significantly improves the manual accessibility of the loading position. The deficiencies of the traditional accumulation and storage type conveying line can be effectively made up, and the load capacity and operation efficiency of the equipment are improved.

[0025] The above only describes the preferred embodiments of the utility model, and does not limit the utility model, and any modification, equivalent replacement and improvement made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
