Description

TECHNICAL FIELD

[0002] In the plate processing industry, especially when processing wood boards, metal plates, plastic plates and other plates, it is necessary to perform deep processing such as sawing and polishing on the plates. During processing, the four faces of the plate often need to be processed, which requires the plate to be overturned by 180 degrees before processing the other face. Due to the limitations of the shape and size of plate parts, it is difficult to use a robot to complete the overturning of plate materials between conveyors, and thus an overturning and feeding device is needed to transport and overturn by 180 degrees the plate to be processed.

[0003] A plate overturning device with an overturning wheel is disclosed in Chinese patent application CN110723513A, which relates to the field of material overturning and comprises a front conveyor belt and a rear conveyor belt. The overturning wheel between the two conveyor belts drives the overturning of the plate. The push assembly can realize the pushing of the material on the front conveyor belt and the pushing out of the rear conveyor belt. Specifically, the overturning wheel is arranged between the conveyor belts for conveying materials. The unturned plate is pushed into the positioning plate on the overturning wheel by the one-way push piece. The turned plate is pushed out of the positioning block of the overturning wheel by the push block, thereby realizing the overturning of the plate during conveying. The overturning efficiency is high, the structure is simple, and the automation degree of plate overturning is greatly improved.

[0004] The above-mentioned overturning device needs to stop the rotation of the overturning wheel before overturning and feeding the plate-shaped workpiece by 180 degrees. Then, the unturned plate is pushed into the positioning plate on the overturning wheel by the one-way push piece. The turned plate is pushed out of the positioning block of the overturning wheel by the push block. Subsequently, the overturning wheel needs to rotate to drive the plate-shaped workpiece to overturn. The plate-shaped workpiece is fed into and out of the positioning plate, and the overturning wheel rotates to drive the workpiece to overturn. The two operations interfere with each other and cannot be performed synchronously. The steps are complicated, which affects the efficiency of workpiece overturning and feeding, is not conducive to continuous and efficient overturning and feeding of plate-shaped workpieces, and has certain limitations, which needs to be improved.

[0047] In actual application, the pushing mechanism 9 rotates clockwise to drive the stop rod two 904 to rotate, at this time, the stop rod two 904 is in the elongated position, when the stop rod two 904 abuts against the stop rod one 1006 in the energy storage type feeding driving mechanism 10, the arc-shaped rack 1004 and the guide block 1003 in the energy storage type feeding driving mechanism 10 rotate clockwise, and the energy storage spring 1005 is extruded to be in the compressed state and store energy, and after the guide column 905 on the pushing mechanism 9 rotates to abut against the V-shaped limiting strip 12, the V-shaped limiting strip 12 guides the guide column 905 to move to the side close to the hollow frame 5, and drives the stop rod two 904 to move synchronously (i.e. the stop rod two 904 shrinks to the side close to the hollow frame 5), so that the stop rod two 904 is in the retracted position.

[0048] The stop rod two 904 has an elongated position and a retracted position, when the stop rod two 904 is in the elongated position, the rotation process of the stop rod two 904 abuts against the stop rod one 1006 to drive the energy storage of the energy storage type feeding driving mechanism 10 and the energy storage type discharging driving mechanism 11, when the stop rod two 904 is in the retracted position, the pushing mechanism 9 releases the limiting of the stop rod one 1006 to release the energy storage of the energy storage type feeding driving mechanism 10 and the energy storage type discharging driving mechanism 11.

At this time, the arc-shaped rack 1004 is moved to reset under the action of the energy storage spring 1005, the arc-shaped rack 1004 is first engaged with the corresponding driven gear 1303, and in the subsequent movement of the arc-shaped rack 1004, the driven gear 1303 is rotated, and then through the cooperation of the rotating shaft 1301, the transmission gear one 1302 and the transmission gear two 1304, the kinetic energy is transmitted to the conveying roller 703 fixedly connected with the transmission gear two 1304 to rotate, and the kinetic energy on the conveying roller 703 is transmitted to the remaining conveying rollers 703 through the transmission belt 704, so that the plurality of conveying rollers 703 synchronously rotate clockwise, thereby conveying the plate-shaped workpiece between the upper feeding roller conveyor mechanism 7 and the lower discharging roller conveyor mechanism 8 through the belt conveyor one 1 and the upper feeding roller conveyor mechanism 7. According to the above principle, the lower discharging roller conveyor mechanism 8 and the belt conveyor two 2 cooperate to convey the plate-shaped workpiece after the turning operation to the belt conveyor two 2.
