Mechanical arm of shovel type stacking machine

Abstract

The invention relates to the field of stacking machines, in particular to a mechanical arm of a shovel type stacking machine. The mechanism arm of the shovel type stacking machine comprises a base plate, a base, a support, a supporting column, a hydraulic arm, a movable arm, a pulley, a balance block and a mechanical shovel. The base comprises a fixed seat arranged on the base plate and a rotary seat arranged on thefixed seat. The support is fixed to the base. The supporting column is vertically fixed to the rotary seat. The two ends of the hydraulic arm are hinged to the supporting column and the movable arm correspondingly. The pulley comprises a driving roller and a fixed pulley which are arranged on the support. One end of a pull wire is fixed to the other end of the movable arm. The middle portion of the pull wire is wound across the fixed pulley. The other end of the pull wire is wound on the driving roller a plurality of circles. The balance block is connected with the other end of the pull wire and suspended. The mechanical shovel is arranged at the tail end of the movable arm. According to the mechanical arm of the shovel type stacking machine, force is transferred through the rope and the pulley, the difference of stress at the two ends of the rope is decreased, in this way, the output torque of a driving motor can be smaller when the mechanical arm moves, and the mechanical arm can save more energy.

Description

technical field

[0001] The invention relates to the field of palletizing machinery, in particular to a shovel-type palletizing mechanical arm. Background technique

[0002] At present, in the field of industrial automation production, various special machines or mechanical arms are used to carry and stack materials to improve operating efficiency and overall productivity. According to the different conditions of the production line and the volume and weight of the material, these devices have different shapes. Compared with special-purpose machines, robotic arms have been widely used in the field of material handling and stacking due to their small footprint, simple structure, flexible operation, and flexible operations. The structural forms of the manipulator are more representative, such as the general-purpose articulated industrial manipulator, or the SCARA-shaped plane coordinate manipulator, etc.

[0003] The above robotic arms have a common problem. Even when the rob...
