Description

Technical Field

[0001] The utility model relates to the technical field of stackers, in particular to a safe automatic stacker. Background Art

[0002] Stacking cranes, also known as stackers, are the most important lifting and transportation equipment in stereoscopic warehouses and are the symbol of the characteristics of stereoscopic warehouses. The main function of stacking cranes is to run back and forth in the passages of stereoscopic warehouses, to store the goods at the entrance of the lanes into the cargo compartments of the shelves, or to take out the goods in the cargo compartments and transport them to the entrance of the lanes. Therefore, stacking cranes have the characteristics of high operating efficiency and high degree of automation, and are used more and more widely in the industrial field, with more and more types. For the process of stacker forks lifting specific heavy objects and storing them in shelves, the stacker's precise loading function is extremely important. At present, stacker loading platforms generally use guide wheels to guide the loading platforms for lifting goods, but due to the adjustment gap between the guide wheels and the certain compensation amount of the guide wheel material itself, the positioning accuracy of the loading platform is low. For some working conditions that require very high positioning of the stacker, the loading platform guided by guide wheels is not applicable.

[0003] In order to solve the above problems, a Chinese utility model patent with authorization announcement number CN220300333U discloses a stacker. This device enhances the working stability of the stacker. At the same time, the stacker saves the electric energy consumed by overcoming the shaking of the cargo platform, and enables the stacker to smoothly and accurately raise and lower the cargo platform to the height required for the operation.

[0004] However, when the device is used, it can only move the objects to be stacked to a specified height, and cannot transfer the objects from the shelf to the loading platform, nor can it transfer the objects on the loading platform to the shelf, and cannot meet the use requirements well.

In this embodiment, the conveying slide seat 44 is slidably installed at the lower end of the loading platform 14 through a chute.

[0024] The working principle of the present utility model: Specifically in use, the moving mechanism 2 drives the moving slide seat 12 to move left and right, and the lifting mechanism 3 drives the loading platform 14 to move up and down. When the loading platform 14 moves to a specified position, the conveying motor 43 is started, and the conveying motor 43 drives the conveying lead screw 42 to rotate, so that the conveying slide seat 44 threadedly sleeved on the conveying lead screw 42 drives the conveying frame 45 to move. When the conveying frame 45 is inserted under the goods, the lifting mechanism 3 drives the loading platform 14 to move up, so that the conveying frame 45 lifts the goods. Subsequently, the conveying motor 43 is started, and the conveying motor 43 drives the conveying lead screw 42 to rotate in the reverse direction, so as to retract the conveying frame 45, and the goods can be transferred to the loading platform 14. By operating in the reverse direction, the goods on the loading platform 14 can be transferred to the shelf. The operation is simple and can better meet the use requirements.

[0025] As a further solution, the moving mechanism 2 includes a moving motor 22 installed on the moving slide seat 12, the output end of the moving motor 22 penetrates through the moving slide seat 12 and is installed with a moving gear 23, a moving rack 21 is further installed at the upper end of the base 1, and the moving rack 21 is meshed with the moving gear 23.

[0026] The working principle of the moving mechanism 2 is as follows: When moving, start the moving motor 22. The moving motor 22 drives the moving gear 23 to rotate, thereby driving the moving slide 21 to move along the moving rack 21. By the forward and reverse rotation of the moving motor, the left and right movement of the moving slide 21 can be realized.

[0027] As a further solution, the stacking rack 13 includes guide rods 131 installed around the upper end of the moving slide 12, and auxiliary rods 133 are also installed on the left and right sides of the upper end of the moving slide 12. The upper ends of the guide rods 131 and the auxiliary rods 133 are installed with a top plate 132.

[0028] As a further solution, the lifting mechanism 3 includes a fixed pulley 34 rotatably installed on the upper half of the auxiliary rod 133. A winding roller 32 is also rotatably installed on the lower half of the auxiliary rod 133. A steel cable 33 is wound on the winding roller 32. The other end of the steel cable 33 bypasses the fixed pulley 34 and is fixedly connected to the upper end of the cargo platform 14. An elevating motor 31 is also installed on the auxiliary rod 133. The output end of the elevating motor 31 is drivingly connected to the shaft end of the winding roller 32. In this embodiment, a through hole 331 is provided at the position corresponding to the steel cable 33 on the upper end of the cargo platform 14.

[0029] The working principle of the lifting mechanism 3 is as follows: When it is necessary to drive the cargo platform 14 to move upward, start the elevating motor 31. The elevating motor 31 drives the winding roller 32 to rotate forward, thereby winding the steel cable 33 onto the winding roller 32. At this time, the cargo platform 14 can be pulled upward through the steel cable 33; when it is necessary to drive the cargo platform 14 to move downward, the elevating motor 31 drives the winding roller 32 to rotate in the reverse direction, thereby releasing the steel cable on the winding roller 32. Under the action of gravity, the cargo platform 14 can move downward.

[0030] In order to limit the cargo platform 14, a limit baffle 134 is also installed on the lower half of the auxiliary rod 133.

[0031] In order to reduce the possibility of the goods falling, a positioning mechanism 5 is also installed at the end of the conveying rack 45. The positioning mechanism 5 includes a positioning seat 51 fixed to the front side of the conveying rack 45. A positioning electric push rod 52 is fixed to the lower end of the positioning seat 51. The telescopic end of the positioning electric push rod 52 penetrates through the positioning seat 51 and is fixed with a positioning baffle 54. A positioning rod 53 is also slidably inserted into the positioning seat 51. The upper end of the positioning rod 53 is fixedly connected to the lower end of the positioning baffle 54.

[0032] The working principle of the positioning mechanism 5 is as follows: After the conveying rack 45 is inserted under the goods, the positioning electric push rod 52 extends, pushing the positioning baffle 54 upward, so that the positioning baffle 54 presses against the goods, preventing the goods from sliding off the front side of the conveying rack 45 and improving the safety of the goods transfer.
