Description

Technical Field

[0001] This disclosure relates to the field of tobacco machinery and equipment, and more particularly to an auxiliary disassembly and assembly device. Background Technology

[0002] The vibratory conveyors widely used in the tobacco industry are mainly crank-rocker type. A crank-rocker type vibratory conveyor is an eccentric connecting rod balanced vibratory device, mainly composed of a trough, frame, balancer, connecting rod assembly, transmission assembly, rocker assembly, and support legs. Due to long-term high-speed operation, the eccentric assembly of the vibratory conveyor is prone to failure of components such as bearings.

[0003] Research has revealed that, due to the limited space below the eccentric part of the vibratory conveyor, disassembling and assembling the eccentric part is difficult, requiring multiple maintenance workers to work together. This process is time-consuming, and downtime for maintenance affects production efficiency and causes a series of negative impacts on the workshop. Furthermore, the eccentric assembly could slip and injure maintenance workers, posing a significant safety hazard. Utility Model Content

[0004] In view of this, the present disclosure provides an auxiliary disassembly and assembly device, which is beneficial to improving the reliability of maintenance of the eccentric assembly of the vibrating conveyor.

[0034] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0035] The vibratory conveyors widely used in the tobacco industry are mainly crank-rocker type. The crank-rocker type vibratory conveyor is an eccentric connecting rod balanced vibratory device, mainly composed of a trough, frame, balance body, connecting rod assembly, transmission assembly, rocker assembly, and support legs.

[0036] During operation, the motor drives the drive shaft to rotate via a narrow V-belt on the pulley. Then, the eccentric device drives the connecting rod to move the balance body. The balance body then drives the trough to perform an approximate simple harmonic vibration in the same direction as the balance body via the rocker assembly. When the vibration acceleration of the trough reaches a certain value, the material will continuously be thrown along the conveying direction in the trough, thereby moving the material forward and achieving the purpose of conveying and loosening the material.

[0037] The transmission assembly of a vibrating conveyor consists of a motor, motor base, pulleys, V-belts, belt covers, eccentric assembly, connecting rods, and a transmission frame. The motor drives the eccentric shaft in the eccentric assembly to rotate via belt drive, and the vibration is transmitted to the balance body by the connecting rods and the transmission frame. Due to long-term high-speed operation, the bearings and other components of the eccentric assembly of the vibrating conveyor are prone to failure.

[0038] Because the space beneath the eccentric assembly of the vibrating conveyor is limited, jamming of the eccentric assembly makes disassembly and reassembly difficult, requiring the cooperation of six maintenance workers: two to pry the eccentric assembly from the left and right, three to support and adjust its position from below, and remove and install bolts, and one to assist by handing over tools. The vibrating conveyor downtime for maintenance is approximately 259 minutes, impacting production efficiency, the company's assessment of workshop failure rates, and OEE (Overall Equipment Effectiveness) indicators. During downtime, auxiliary equipment runs idle, wasting energy; production interruption affects process QI (Quality Indicator) scores; and maintenance increases the drying load of subsequent yarn drying machines, leading to material waste. Therefore, prolonged downtime for maintenance has a series of negative impacts on the workshop. The eccentric assembly slipping could injure maintenance workers and pose a safety hazard.

[0039] In view of this, in one aspect of the present disclosure, an auxiliary disassembly and assembly device is provided for disassembling and assembling the eccentric assembly of a vibrating conveyor, which is beneficial to improving the reliability of maintenance operations of the eccentric assembly of the vibrating conveyor.

[0040] Figure 1 These are schematic diagrams of some embodiments of the assisted disassembly and assembly device according to this disclosure, with reference to... Figure 1 The auxiliary disassembly and assembly device includes a load-bearing component 1, a lifting component 2, and a moving component 3.

[0041] The support member 1 is used to support the eccentric assembly. The support member 1 is designed according to the shape and dimensions of the eccentric assembly to stably and reliably support it during assembly and disassembly. The lifting member 2 is located below the support member 1 and is telescopic to raise or lower the support member 1, allowing it to be raised or lowered to a suitable height. The moving member 3 is located below the lifting member 2 and is configured to move either the lifting member 2 or the support member 1, facilitating the transport and movement of the auxiliary assembly and disassembly device.

[0042] During the experiment, the auxiliary disassembly and assembly device only required 3 operators: 1 person to disassemble and assemble the bolts, 1 person to adjust the height of the lifting component 2, and 1 person to assist in the positioning of the eccentric assembly and the auxiliary disassembly and assembly device. The total disassembly and assembly time was 57 minutes, which reduced the number of maintenance personnel by half and saved half of the disassembly and assembly time of the vibrating conveyor eccentric assembly.

[0043] In this embodiment, by setting up an auxiliary disassembly and assembly device that can be extended and moved, the eccentric assembly can be adaptively supported according to maintenance needs, and can flexibly enter a narrow working space to carry out operations, thereby greatly reducing the disassembly and assembly time of the eccentric assembly, reducing the number of maintenance personnel, reducing the labor intensity of maintenance personnel, and making maintenance operations safer and more reliable.

[0044] refer to Figure 1 , Figure 1 In the first direction, direction A is the first direction. In some embodiments, the carrier 1 extends along the first direction, and the cross section of the carrier 1 in a plane perpendicular to the first direction is arc-shaped so as to fit with the outer periphery of the eccentric assembly.

[0045] In this embodiment, by making the cross-section of the support member 1 arc-shaped, it is possible to better match the outer periphery of the eccentric assembly, reduce the relative displacement between the eccentric assembly and the support member 1, and minimize the shaking and / or sliding of the eccentric assembly during maintenance operations, thereby reducing the safety hazard of the eccentric assembly falling and injuring maintenance personnel.

[0046] refer to Figure 1 In some embodiments, the auxiliary disassembly and assembly device further includes a limiting member 4, which is disposed at both ends of the support member 1 along the first direction to limit the displacement of the eccentric assembly.

[0048] refer to Figure 1 In some embodiments, there are multiple limiting members 4, which are equidistantly spaced along the arc cross-section of the bearing member 1. In this embodiment, the number of limiting members 4 can be adjusted according to actual needs. The limiting members 4 are equidistantly spaced along the arc cross-section of the bearing member 1 to achieve a better limiting effect.

[0049] refer to Figure 1 In some embodiments, the limiting member 4 is plate-shaped. In this embodiment, the limiting member 4 may be in the form of a plate, and the limiting surface of the limiting member 4 is perpendicular to the inner circumferential direction of the bearing member 1, so as to achieve a better limiting effect and more reliably ensure operational safety.

[0050] refer to Figure 1In some embodiments, the lifting member 2 is rhomboid in shape and has a first lifting part 21 and a second lifting part 22 arranged symmetrically. The first lifting parts 21 are configured to be far apart from each other to drive the carrier member 1 to descend and close together to drive the carrier member 1 to rise.

[0051] A hinge point is provided at the midpoint of the first lifting part 21 and the second lifting part 22. A locking member 7 can be inserted through the hinge point in the first direction to lock the lifting height of the lifting part 2.

[0052] In this embodiment, the use of a rhomboid lifting component 2 can achieve smooth lifting and lowering, a large lifting range, and a small footprint, enabling it to complete the operation flexibly and stably within the narrow space of the eccentric assembly.

[0053] refer to Figure 1 In some embodiments, the lifting component 2 includes a jack. In this embodiment, the lifting component 2 may be a diamond rack and pinion jack, which can bear a weight of 0.5 tons and a lifting height of about 15 centimeters, reliably meeting the lifting and operation requirements.

[0054] refer to Figure 1 In some embodiments, the auxiliary disassembly and assembly device further includes a base 5, disposed between the lifting component 2 and the moving component 3, and connected to both the lifting component 2 and the moving component 3. In this embodiment, the base 5 improves the stability and structural strength of the auxiliary disassembly and assembly device, and facilitates the installation of adjacent components.

[0055] refer to Figure 1 In some embodiments, the movable component 3 includes multiple casters, which are disposed at the bottom of the base 5. In this embodiment, the movable component 3 may be in the form of casters, with one caster at each of the four ends of the bottom of the base 5, so that the auxiliary disassembly and assembly device can move in any direction.

[0056] refer to Figure 1 In some embodiments, the auxiliary disassembly and assembly device further includes a support base 6, which is disposed between the load-bearing member 1 and the lifting member 2, and connected to both the load-bearing member 1 and the lifting member 2 respectively. In this embodiment, the support base 6 helps to improve the stability of the eccentric assembly support and facilitates the installation of adjacent components. A reinforcing member 8 is also provided on the support base 6 to support the load-bearing member 1.

[0057] The auxiliary disassembly and assembly device provided in this disclosure is lightweight (approximately 10 kg), highly mobile, and easy to lift (an extended rocker arm can be used to extend outside the vibrating conveyor for lifting operations). It is suitable for disassembling and assembling all eccentric assemblies of vibrating conveyors with a height greater than 20 cm from the ground. For eccentric assemblies with a height greater than 50 cm, the trolley can be placed on a stable platform of suitable height for disassembly and assembly. This device fills the gap in the industry for auxiliary tools for replacing eccentric assemblies of vibrating conveyors and has broad application value. It can not only reduce the investment of maintenance personnel, reduce the labor intensity of maintenance personnel, and save disassembly and assembly time, but also eliminate the safety hazard of eccentric assemblies falling and injuring maintenance personnel.
