Description

Convertible angle rotary transport mechanism

The invention relates to a convertible angle rotary transport mechanism, in particular to a rotary transport mechanism for transporting processed objects from a transport mechanism side to any travel position and a predetermined parking angle.

As is known, in the processing or manufacturing process of the general processing industry or manufacturing industry, it is often necessary to move or move the semi-finished or finished products of the static fixed point or the moving belt in the worktable or the rack to the dynamic fixed point. Another machining point or moving point.

Conventional processing or manufacturing is carried out by means of a means of transporting a semi-finished product or a finished product from one place to another by a straight or rotary handling device with a clamp or suction cup at the end.

In the conventional transportation method, the fixed-direction processed object is transported from one position to another in a fixed position by linear motion of the slide rail, or the fixed-direction processed object is transported from one position to another by a rotary motion. In another position in a fixed direction, it is obvious that it cannot be changed in direction or angle. If the direction or angle is changed, it must be provided with two handling mechanisms, but It will inevitably increase the operating space and institutional equipment.

The invention utilizes a specific slewing mechanism design to achieve a rotary transport mechanism that can change the angle of the workpiece to be conveyed, and is specially designed for the production line to transport the processed object from the side of the transport mechanism to any travel position and a predetermined parking angle.

The transport mechanism of the present invention utilizes a swivel arm and connects one end thereof to a rotating shaft of a rotary power member on a U-shaped frame, and a swing timing wheel is disposed on the other end of the swing arm.

In the transport mechanism of the present invention, a fixed timing wheel is disposed on the U-shaped frame, and the rotating timing wheel and the fixed timing wheel are coupled by a timing belt.

In the transport mechanism of the present invention, the swing arm is driven by a rotary cylinder or a servo motor of a rotary power member and rotates the other end, and the swing timing wheel is driven by the timing belt (7) with the fixed timing wheel as a fulcrum.

In the transport mechanism of the present invention, a gripping mechanism or a suction mechanism is disposed on one side of the swing timing wheel, and the workpiece is gripped or sucked and transported by the transport mechanism side to any stroke position and a predetermined parking angle.

In the transport mechanism of the present invention, the transport stroke of the workpiece to be transported is controlled by the rotational stroke setting of the rotary power member, and the stopping angle of the transported workpiece is controlled by changing the ratio of the fixed timing wheel and the swing timing gear.
