Description

Technical Field

[0001] The invention relates to a heavy-load roller conveyor, in particular to a deviation-correcting mechanism for conveying goods on the heavy-load roller conveyor. Background Art

[0002] The heavy-duty roller conveyor is composed of a frame and legs. A plurality of double-chain conveyor rollers are installed on the frame. The box to be conveyed is set on the conveyor roller. Two driving sprockets are fixedly arranged at the ends of the double-chain conveyor rollers. The driving motor drives the driving sprocket to output power, which is then transmitted to one of the sprockets of the conveyor roller through the chain. The other sprocket on the conveyor roller drives the other rollers in series one by one through the ring chain. Since the two sprockets at the ends of the double-chain rollers are connected to the rollers as an integrated structure, when the motor rotates and outputs, the rollers on the entire chain roller conveyor will rotate together. When the rollers rotate, the goods above are driven for conveying. In the process of box-type goods being conveyed, due to the different specifications of the conveyed goods and after being conveyed and transferred through multiple roller conveyors, the box-type goods will be skewed during the conveying process, and will be blocked during the subsequent conveying and transfer. Once the blocking phenomenon occurs, it will seriously affect the normal operation of the entire conveyor line. How to automatically correct, regularize and correct the skewed goods in time during the conveying process has become a problem that needs to be solved urgently on site. Summary of the invention

[0003] The invention provides a deviation correction mechanism for conveying goods on a heavy-load roller conveyor, which solves the technical problem of how to automatically correct, regularize and amend the skewed goods in a timely manner during the conveying process.

[0004] The present invention solves the above technical problems through the following technical solutions:

[0005] A deviation correction mechanism for conveying goods on a heavy-duty roller conveyor comprises a heavy-duty roller conveyor frame, rollers are arranged on the heavy-duty roller conveyor frame, rectangular box-shaped goods are conveyed on the rollers, a monitor for the conveying posture of the rectangular box-shaped goods and an electronic controller for a deviation correction driving cylinder are respectively installed on the heavy-duty roller conveyor frame, a deviation correction mechanism installation base plate is arranged on the heavy-duty roller conveyor frame below the rollers, a hinge seat is arranged at the front side end of the deviation correction mechanism installation base plate, a deviation correction driving cylinder tail installation plate is hinged on the hinge seat, and a deviation correction driving cylinder tail installation plate is arranged on the deviation correction driving cylinder tail installation plate A correction drive cylinder is arranged in the horizontal direction, and a second pin shaft and a third pin shaft are respectively arranged in the middle part of the base plate for installing the correction mechanism, the middle part of the active V-shaped swing plate is hinged on the second pin shaft, and the driven V-shaped swing plate is hinged on the third pin shaft. The lower end of the active V-shaped swing plate and the end part of the output shaft of the correction drive cylinder are hinged together through the first pin shaft, a fourth pin shaft is arranged on the active V-shaped swing plate above the second pin shaft, and a fifth pin shaft is arranged on the driven V-shaped swing plate below the third pin shaft, one end of the S-shaped connecting rod is hinged on the fourth pin shaft, and the other end of the S-shaped connecting rod is hinged on the fifth pin shaft.

[0006] A middle rotating cylindrical box is arranged in the middle of the active V-shaped swing plate, a pair of bearings are arranged on the middle rotating cylindrical box, the second pin shaft is movably connected in the pair of bearings, and the end of the second pin shaft is fixedly connected to the correction mechanism mounting base plate through connecting screws.

[0007] A method for correcting a deviation of a correction mechanism for conveying goods on a heavy-load roller conveyor, comprising the following steps:

[0008] The first step is that when the monitor of the conveying posture of the rectangular box-shaped goods finds that the rectangular box-shaped goods pre-transmitted to the installation base plate of the correction mechanism are skewed, a correction electric signal is sent out. After receiving the correction electric signal, the correction drive cylinder electronic controller controls the output shaft of the correction drive cylinder to extend. The output shaft of the correction drive cylinder drives the active V-shaped swing plate to rotate and swing clockwise through the first pin shaft, so that the upper end of the active V-shaped swing plate swings to the top of the roller. At the same time, as the active V-shaped swing plate rotates and swings clockwise, the active V-shaped swing plate drives the driven V-shaped swing plate to rotate and swing counterclockwise through the hinged S-shaped connecting rod, so that the upper end of the driven V-shaped swing plate swings to the top of the roller at the same time;

[0009] The second step is that the inclined rectangular box-shaped cargo continues to move toward the raised active V-shaped swing plate and the driven V-shaped swing plate under the transmission of the rollers. When the forward inclined part of the rectangular box-shaped cargo contacts the raised active V-shaped swing plate, the forward inclined part of the rectangular box-shaped cargo is blocked by the active V-shaped swing plate. Due to the rotation transmission of the rollers under the rectangular box-shaped cargo, the backward inclined part of the rectangular box-shaped cargo will continue to move forward, causing the rectangular box-shaped cargo to rotate and move at the raised active V-shaped swing plate and the driven V-shaped swing plate until the front side elevation of the rectangular box-shaped cargo is completely in contact with the upper end of the active V-shaped swing plate and the upper end of the driven V-shaped swing plate, thereby realizing the correction of the transmission posture of the inclined rectangular box-shaped cargo;

[0010] The third step is that when the monitor of the conveying posture of the rectangular box-shaped goods detects that the correction of the rectangular box-shaped goods is completed, it sends out a release signal. After the electronic controller of the correction drive cylinder receives the release signal, it retracts the output shaft of the correction drive cylinder, and the active V-shaped swing plate rotates counterclockwise. At the same time, the driven V-shaped swing plate rotates clockwise. The upper ends of the active V-shaped swing plate and the driven V-shaped swing plate swing synchronously to the bottom of the roller, removing the obstruction to the rectangular box-shaped goods. The rectangular box-shaped goods with corrected conveying posture pass through the base plate where the correction mechanism is installed and continue to be conveyed forward.

[0011] The two V-shaped rocker mechanisms of the present invention are arranged under the rollers of the roller conveyor line. The two V-shaped blocking plates are driven to swing by the cylinder to block the forward direction of the goods. After the skewed goods contact one of the blocking plates, they will be forced to correct the deviation online under the conveying action of the rollers. After the blocking plates on both sides have all taken effect, the blocking plates will be opened to allow the goods to be conveyed forward. The present invention has a simple structure and is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] A middle rotating cylindrical box 18 is arranged in the middle of the active V-shaped swing plate 9, that is, the structure of the active V-shaped swing plate 9 is a middle rotating cylindrical box 18, and the two ends are the structural form of swing plates, and bearings 17 are respectively arranged on the two parallel side elevations of the middle rotating cylindrical box 18, and the second pin shaft 10 is movably connected in a pair of bearings 17, and the end of the second pin shaft 10 is fixedly connected to the correction mechanism mounting base plate 4 through the connecting screw 16, that is, the second pin shaft 10 is fixedly connected to the inner ring of the two bearings 17, and the second pin shaft 10 is fixed on the correction mechanism mounting base plate 4, and the middle rotating cylindrical box body 18 can rotate around the second pin shaft 10 to realize the swing of the active V-shaped swing plate 9; the structure of the driven V-shaped swing plate 11 is exactly the same as that of the above-mentioned active V-shaped swing plate 9.

[0019] A method for correcting a deviation of a correction mechanism for conveying goods on a heavy-duty roller conveyor. A rectangular box-shaped cargo 3 is conveyed on a heavy-duty roller conveyor behind an installation position of a base plate 4 for the correction mechanism. During the conveying process, the cargo may be skewed due to various reasons, that is, the front side elevation of the rectangular box-shaped cargo 3 is not perpendicular to the central axis of the conveying line of the heavy-duty roller conveyor. The correction is performed by the following steps:

[0020] The first step is that when the monitor of the conveying posture of the rectangular box-shaped goods 3 finds that the rectangular box-shaped goods 3 pre-transmitted to the installation base plate 4 of the correction mechanism are skewed, a correction electric signal is sent out. After receiving the correction electric signal, the correction drive cylinder electronic controller controls the output shaft of the correction drive cylinder 7 to extend. The output shaft of the correction drive cylinder 7 drives the active V-shaped swing plate 9 to rotate and swing clockwise through the first pin shaft 8, so that the upper end of the active V-shaped swing plate 9 swings to the top of the roller 2. At the same time, as the active V-shaped swing plate 9 rotates and swings clockwise, the active V-shaped swing plate 9 drives the driven V-shaped swing plate 11 to rotate and swing counterclockwise through the hinged S-shaped connecting rod 14, so that the upper end of the driven V-shaped swing plate 11 swings to the top of the roller 2 at the same time;

[0021] In the second step, the inclined rectangular box-shaped cargo 3 continues to move toward the raised active V-shaped swing plate 9 and the driven V-shaped swing plate 11 under the transmission of the roller 2. When the forward inclined part of the rectangular box-shaped cargo 3 contacts the raised active V-shaped swing plate 9, the forward inclined part of the rectangular box-shaped cargo 3 is blocked by the active V-shaped swing plate 9. Due to the rotation transmission of the roller 2 below the rectangular box-shaped cargo 3, the backward inclined part of the rectangular box-shaped cargo 3 will continue to move forward, causing the rectangular box-shaped cargo 3 to rotate and move at the raised active V-shaped swing plate 9 and the driven V-shaped swing plate 11 until the front side elevation of the rectangular box-shaped cargo 3 is completely in contact with the upper end of the active V-shaped swing plate 9 and the upper end of the driven V-shaped swing plate 11, thereby realizing the correction of the transmission posture of the inclined rectangular box-shaped cargo 3;

[0022] The third step is that when the monitor of the conveying posture of the rectangular box-type goods 3 detects that the correction of the rectangular box-type goods 3 is completed, it sends out a release electrical signal. After receiving the release electrical signal, the electronic controller of the correction drive cylinder retracts the output shaft of the correction drive cylinder 7, and the active V-shaped swing plate 9 rotates counterclockwise. At the same time, the driven V-shaped swing plate 11 rotates clockwise. The upper ends of the active V-shaped swing plate 9 and the driven V-shaped swing plate 11 swing synchronously to the bottom of the roller 2, thereby removing the obstruction to the rectangular box-type goods 3. The rectangular box-type goods 3 with corrected conveying posture are continuously conveyed forward through the base plate 4 where the correction mechanism is installed.
