Description

Technical Field

[0001] The present invention relates to a logistics and ship logistics conveying device, in particular to an automatic goods turnover and righting mechanism. Background Art

[0002] In warehousing logistics and ship logistics conveying equipment, due to functional and conveying route requirements, the initial state of the initially conveyed goods, such as lying horizontally, standing upright, or tilting, needs to be changed accordingly. To achieve such conversions, corresponding actuating mechanisms are often added to complete the task. Such actuating mechanisms are generally driven by electricity or hydraulics, which results in a complex structure of the conveying line and a decrease in the conveying rhythm, thus affecting the conveying efficiency.

[0003] To simplify the operation process and improve the conveying efficiency, it is hoped that the change of the goods state during the conveying process can be automatically completed through the transmission chain, so that no other actuating mechanisms need to be set, especially without affecting the rhythm, with simple control, ensuring the safety, reliability, and efficiency of the conveying line. Summary of the Invention

[0004] To solve the above problems, the present invention provides an automatic goods turnover and righting mechanism, which controls and solves the problems of goods state change and restoration during the goods conveying process through the bumpers on the chain.

[0005] To achieve the above object, the technical solution of the present invention is: an automatic goods turnover and righting mechanism, including a goods bracket, a rocker arm, a swing arm, a tie rod assembly, and a bumper.

[0006] The goods bracket is used for placing goods and can rotate around an axis to turnover the goods.

[0007] The rocker arm is connected to the goods bracket through a shaft installed at a fixed position in the middle, and is used to drive the goods bracket and the goods to turnover.

[0008] Two swing arms are respectively fixed to two upper and lower fixed positions below the goods bracket through shafts, and can respectively rotate around their own shafts.

[0009] The tie rod assembly has a long tie rod and a short tie rod. The two ends of the long tie rod are respectively hinged to one end of the rocker arm and one end of the swing arm at a lower fixed position through pin shafts; the two ends of the short tie rod are respectively hinged to the other end of the rocker arm and one end of the swing arm at an upper fixed position through pin shafts, and is used as a connecting rod for the swing arm to drive the rocker arm.

[0010] The bumper is connected to the transmission chain through a pin shaft and is located on the connection line of the impact positions of the two swing arms, and is used for the transmission chain to drive and respectively impact the two swing arms to achieve the turnover and righting of the goods bracket and the goods.

[0011] Further, the rocker arm is of a symmetric structure, with a connection hole in the middle and pin holes for connecting the tie rods at both ends.

[0012] Further, the swing arm is in a "Y" shape, with a swivel hole in the middle, a connecting pin hole for the pull rod at the lower end, and an impact boss on the inner side of the upper end.

[0013] Further, the long pull rod and the short pull rod are pull rods with adjustable lengths.

[0014] Further, the drive chain is driven by a motor and can make a circular motion around the upper and lower sprockets.

[0015] The beneficial effects of the present invention are as follows:

[0016] For the automatic goods flipping and righting mechanism of the present invention, through the bumpers installed on the drive chain, when the chain runs forward to the specified position, the bumper impacts the first swing arm, which can rotate or tilt the goods. When the chain continues to run, the bumper impacts the second swing arm, which can right the goods. When the chain runs in the reverse direction, the bumper first impacts the second swing arm to rotate or tilt the goods, and when the chain continues to run, the bumper impacts the first swing arm to right the goods. Through the automatic flipping and righting mechanism, there is no need to add additional power sources such as motors or hydraulics, and the state change of the goods during transportation, such as flipping and righting, is completed by the drive chain itself. The control is simple, without changing the speed and direction of the drive chain, and without affecting the conveying rhythm.

[0017] If the present invention can be applied to logistics equipment, especially ship logistics, it can simplify the structure of logistics equipment and improve the conveying efficiency of logistics equipment. Description of the Drawings

[0023] The present invention will be further described below in conjunction with the drawings and embodiments.

[0024] As Figures 1 to 5As shown in the figure, the automatic flipping and righting mechanism for goods of the present invention includes a first rotating arm 2, a second rotating arm 9, a first pull rod 3, a second pull rod 8, a first rocker arm 4, a second rocker arm 7, a first shaft 1, a second shaft 10, a third shaft 5, a goods bracket 6, a bumper 11, etc.

[0025] The first rotating arm 2, the first pull rod 3, and the first rocker arm 4 are connected into one body through a pin shaft. The second rotating arm 9, the second pull rod 8, and the second rocker arm 7 are connected into one body through a pin shaft. The first rotating arm 2 and the second rotating arm 9 are respectively sleeved on the first shaft 1 and the second shaft 10. The first shaft 1 and the second shaft 10 are respectively installed at a fixed position. The first rocker arm 4 and the second rocker arm 7 are sleeved on another third shaft 5. One end of the third shaft 5 is installed at a fixed position, and the other end is installed on the goods bracket 6. The bumper 11 is connected to the transmission chain through a pin shaft.

[0026] On a conveyor line driven by a chain, to realize the flipping of goods at a fixed position, such as for the convenience of grasping and assembling goods, the goods need to be flipped by a certain angle. After the operation is completed, the goods need to be righted for convenient transportation. The above functions can be realized through the automatic flipping and righting mechanism, as follows:

[0027] A bumper 11 is installed at a corresponding position of the chain. The bumper 11 can be connected to the chain through a pin shaft. The first shaft 1, the second shaft 10, and the third shaft 5 are respectively installed at a fixed position. The goods bracket 6 is installed on the third shaft 5. After the first rotating arm 2, the first pull rod 3, and the first rocker arm 4 of the automatic flipping and righting mechanism are connected into one body through a pin shaft, one end is connected to the first shaft 1, and the other end is connected to the third shaft 5. After the second rotating arm 9, the second pull rod 8, and the second rocker arm 7 are connected into one body through a pin shaft, one end is connected to the second shaft 10, and the other end is connected to the third shaft 5. When the chain runs upward clockwise, the bumper 11 on the chain first hits the first rotating arm 2, and the first rotating arm 2 rotates counterclockwise around the first shaft 1. When the first rotating arm 2 rotates counterclockwise, it drives the first pull rod 3 to move downward. When the first pull rod 3 moves downward, it drives the first rocker arm 4 and the third shaft 5 to rotate counterclockwise. When the third shaft 5 rotates counterclockwise, it drives the goods bracket 6 and the goods 12 to flip counterclockwise by an angle, and at the same time drives the second rocker arm 7 to rotate counterclockwise. When the second rocker arm 7 rotates counterclockwise, it drives the second pull rod 8 to move upward. When the second pull rod 8 moves upward, it drives the second rotating arm 9 to rotate counterclockwise around the second shaft 10 by an angle, completing the flipping of the goods bracket 6 and the goods 12; the chain continues to move upward, and the bumper 11 hits the second rotating arm 9. The second rotating arm 9 rotates clockwise around the second shaft 10. When the second rotating arm 9 rotates clockwise, it drives the second pull rod 8 to move downward. When the second pull rod 8 moves downward, it drives the second rocker arm 7 and the third shaft 5 to rotate clockwise. When the third shaft 5 rotates clockwise, it drives the goods bracket 6 and the goods 12 to be righted clockwise, and at the same time drives the first rocker arm 4 to rotate clockwise. When the first rocker arm 4 rotates clockwise, it drives the first pull rod 3 to move upward. When the first pull rod 3 moves upward, it drives the first rotating arm 2 to rotate clockwise around the first shaft 1 by an angle. By the bumper 11 hitting the first rotating arm 2 and the second rotating arm 9 successively, one flipping and righting of the goods bracket 6 and the goods 12 is completed.

[0028] The power for the striker to impact the swing arm comes from the traction force of the chain during the chain drive process, without the need for additional driving force. The angles of the cargo bracket and the cargo flipping are determined by the shapes, dimensions, and relative positions of the swing arm, tie rod, rocker arm, and shaft.

[0029] Provide a simple mechanical drive mechanism, skillfully utilize the traction force along with the chain drive, through the circular and reciprocating motion of the chain, and according to the rhythm requirements of the conveying process, reasonably complete the flipping and righting of the cargo bracket and the cargo through pure mechanical motion according to the positions of shaft one, shaft two, and shaft three.

[0030] The specific application and implementation process of the present invention is as follows:

[0031] When it is necessary to complete the conveyance of a certain cylindrical cargo on the ship, an electric motor drives the chain to make a circular motion around the upper and lower sprockets to complete the upward or downward conveyance of the cargo between the upper deck and the lower deck. When the cargo is conveyed from the lower deck to the upper deck, it is necessary to manually take out the cargo from the cargo bracket; when the cargo is conveyed from the upper deck to the lower deck, it is necessary to manually load the cargo into the cargo bracket. Due to reasons such as the relatively heavy weight and smooth appearance of the cylindrical cargo, it is inconvenient to take out and load the cargo. The cargo bracket and the cargo can be flipped by a certain angle to achieve the purpose of facilitating the taking out and loading of the cargo.

[0032] Set up two sprockets, the upper and the lower. The lower sprocket is driven by the motor reducer to drive the chain to make a circular motion around the upper and lower sprockets. The chain moves upward clockwise to complete the upward conveyance of the cargo, and the chain moves downward counterclockwise to complete the downward conveyance of the cargo.

[0033] According to the physical characteristics such as the position of the cargo outlet on the upper deck, the external dimensions of the cargo, and the required flipping angle of the cargo, install shaft one, shaft two, and shaft three at the positions shown in the figure. Shaft one 1, swing arm one 2, tie rod one 3, rocker arm one 4, shaft three 5, cargo bracket 6, rocker arm two 7, tie rod two 8, swing arm two 9, and shaft (two) 10 are connected by pin shafts to form an automatic flipping and righting mechanism. Install a striker on the chain, and the striker is usually connected to the chain through a chain pin shaft; Figure 1 This is the initial state of the automatic flipping and righting mechanism.

[0034] When conveying the cargo upward:

[0035] The striker on the chain first impacts the swing arm one 2, and the swing arm one 2 rotates counterclockwise around the shaft one 1. When the swing arm one 2 rotates counterclockwise, it drives the tie rod one 3 to move downward. When the tie rod one 3 moves downward, it drives the rocker arm one 4 and the shaft three 5 to rotate counterclockwise. When the shaft three 5 rotates counterclockwise, it drives the cargo bracket and the cargo to flip counterclockwise by an angle, and at the same time drives the rocker arm two 7 to rotate counterclockwise. When the rocker arm two 7 rotates counterclockwise, it drives the tie rod two 8 to move upward. When the tie rod two 8 moves upward, it drives the swing arm two 9 to rotate counterclockwise around the shaft two 10 by an angle, completing the flipping of the cargo bracket and the cargo; The flipping state is asFigure 2 As shown

[0036] After the operator takes away the goods, the chain continues to move upward. The collision block hits the second swing arm 9, and the second swing arm 9 rotates clockwise around the second shaft 10. When the second swing arm 9 rotates clockwise, it drives the second pull rod 8 to move downward. When the second pull rod 8 moves downward, it drives the second rocker arm 70 and the third shaft 5 to rotate clockwise. When the third shaft 5 rotates clockwise, it drives the goods bracket and the goods to be righted clockwise. At the same time, it drives the first rocker arm 4 to rotate clockwise. When the first rocker arm 4 rotates clockwise, it drives the first pull rod 3 to move upward. When the first pull rod 3 moves upward, it drives the first swing arm 2 to rotate clockwise around the first shaft 1 by an angle. The righted state is as Figure 3 shown

[0037] Conveying goods downward:

[0038] The chain moves downward. The collision block on the chain first hits the second swing arm 2, and the second swing arm 2 rotates counterclockwise around the second shaft 10. When the second swing arm rotates counterclockwise, it drives the second pull rod 8 to move upward. When the second pull rod moves upward, it pushes the second rocker arm 7 and the third shaft 5 to rotate counterclockwise. When the third shaft 5 rotates counterclockwise, it drives the goods bracket 6 to flip counterclockwise by an angle. At the same time, it drives the first rocker arm 4 to rotate counterclockwise. When the first rocker arm 4 rotates counterclockwise, it drives the first pull rod 3 to move downward. The downward movement of the first pull rod 3 drives the first swing arm 2 to rotate counterclockwise around the first shaft 1 by an angle, completing the flipping of the goods bracket. The flipped state is as Figure 4 shown

[0039] After the operator loads the goods into the goods bracket, the chain continues to move downward. The collision block on the chain hits the first swing arm 2, and the first swing arm 2 rotates clockwise around the first shaft 1. When the first swing arm 2 rotates clockwise, it drives the first pull rod 3 to move upward. When the first pull rod 3 moves upward, it pushes the first rocker arm 4 and the third shaft 5 to rotate clockwise. When the third shaft 5 rotates clockwise, it drives the goods bracket and the goods to be righted. At the same time, it drives the second rocker arm 7 to rotate clockwise. When the second rocker arm 7 rotates clockwise, it drives the second pull rod 8 to move downward. The downward movement of the second pull rod 8 drives the second swing arm 9 to rotate clockwise around the second shaft 10 by an angle, completing the righting of the goods bracket and the goods. The righted state is as Figure 5 shown

[0040] Multiple collision blocks can be set on the chain to achieve multiple flips and rightings of the goods during the conveying process. Both flipping and righting are completed by the collision blocks on the chain.
