Description

Technical Field

[0001] The utility model belongs to the field of conveyors, and in particular relates to a selective workpiece conveyor. Background Art

[0002] A conveyor is a material handling machine that continuously transports materials along a defined route, also known as a continuous conveyor. Conveyors can transport materials horizontally, inclined, and vertically. They offer high transport capacity, long distances, and the ability to simultaneously perform multiple process operations, making them widely used. Current conveyor routes are typically fixed. When machining parts in workshops, different routes are often required depending on the type of part being processed. This presents a problem: fixed-route conveyors cannot provide directional transport as needed. Utility Model Content

A lifting frame is provided corresponding to the frame, and two left-right symmetrical longitudinal conveying assemblies are provided on the lifting frame. The two groups of conveying assemblies are respectively located between the two conveying rollers on the left side and the two conveying rollers on the right side.

[0005] The present invention is designed to interface with a conveyor line. The transverse conveyor line transports rod-shaped workpieces to longitudinal conveyor rollers. Depending on the type of workpiece, the workpieces are then transported rearwards via the conveyor rollers to a rear transverse conveyor line, or the conveyor rollers pause to transport the workpieces to a side longitudinal conveyor line via the longitudinal conveyor belt. Compared to existing technologies, the present invention offers the advantage of enabling positioning and conveying based on the type of workpiece being processed. Specifically, the workpieces are transported to different conveyor lines based on their quality, allowing for screening and classification of qualified and defective products, providing greater flexibility and convenience. The present invention is designed to transport rod-shaped workpieces, which are placed transversely on the conveyor rollers.

[0006] As a further improvement of the present invention, the frame includes two corresponding front and rear side brackets, the bottoms of the two side brackets are fixed to the rectangular outer frame, and the four corners of the lower side of the outer frame are provided with supporting feet. The rear side bracket is provided with a groove corresponding to the conveying assembly. The groove facilitates the passage of workpieces.

[0007] As a further improvement of the present invention, the front and rear roller shafts of each conveyor roller are rotatably connected to two side brackets, and two sprockets are axially spaced apart on the front roller shaft of each conveyor roller. The corresponding sprockets of two adjacent conveyor rollers on the left and right are connected by a chain transmission. Any two adjacent chains on the left and right are staggered along the axial direction of the conveyor rollers. The front roller shaft of any conveyor roller passes through the side bracket and is transmission-connected to a reduction motor. The reduction motor drives any conveyor roller to rotate, and the linked conveyor rollers rotate simultaneously.

The side mounting plates include a horizontal upper mounting portion and a vertical lower mounting portion, and a reducer is disposed between the lower mounting portions of the two conveyor frames, the input shaft at the lower end of the reducer being connected to a drive motor, the output shafts on the left and right sides of the reducer being connected to a transmission shaft, and the axles of the two sprockets 3 on the left and right sides each passing through the corresponding side mounting plates and connected to the corresponding transmission shaft via a coupling. The drive motor drives sprocket 3 to rotate via the transmission shafts on the left and right sides of the reducer, and sprocket 3 drives sprocket 1 and sprocket 2 to rotate. When the lifting frame is raised, defective workpieces placed horizontally are transported to the side by the two chains 2, thereby screening the defective workpieces, and the length of the rod-shaped workpiece is greater than the distance between the two chains 2.

These guide assemblies include fixed sleeves movably connected to guide rods, the upper ends of which are fixed to the lifting frame. The underside of the lifting frame is also provided with four rectangular cylinders, the extended ends of the cylinder piston rods of which are in driving connection with the lifting frame.
