Description

Technical Field

[0001] The present application relates to the technical field of storing single or sequentially arranged objects in a warehouse or storehouse, and in particular to a high-speed stacker. Background Art

[0002] The stacker's lifting mechanism is used to achieve vertical lifting of materials, and mainly adopts three methods to lift materials: chain lifting, wire rope drum lifting and wire rope traction wheel lifting.

[0003] Wire rope drum hoisting is generally composed of a drum, a reduction motor, a wire rope and a pulley block. Its working principle is: the reduction motor drives the drum to rotate and wind the wire rope, and then the heavy object is lifted through the wire rope and the pulley block, but the lifting speed is slow;

[0004] The traction lifting mechanism is mainly composed of traction device, traction wheel, wire rope, guide wheel and anti-rope wheel. One end of the traction wire rope is connected to the cargo platform, and the other end is connected to the counterweight device. The gravity of the cargo platform, the counterweight device and the load makes the wire rope pressed tightly in the rope groove of the traction wheel to generate sufficient friction to drive the heavy object to move up and down along the guide rail. The advantage of the traction lifting mechanism is that the transmission mechanism is small in size, but the stacker is different from the elevator in that it needs to move horizontally, so the counterweight device is bound to shake and produce noise, and the counterweight device needs to be set inside the column and move up and down along the inner wall of the column, which is troublesome to repair and install.

[0005] The chain lifting mechanism mainly consists of a lifting motor (including a reducer), a transmission sprocket, a transmission chain, a double sprocket, a lifting chain and a redirecting sprocket. When the lifting motor drives the double sprocket to rotate through the transmission chain, the lifting chain moves, thereby driving the cargo platform (including the cargo fork (403) and the cargo) to rise and fall. Compared with the steel wire rope, the garage using the chain lifting method has much better stability during the lifting process, but the chain will make a loud noise during the lifting process.

[0006] In view of the shortcomings of the lifting mechanism currently used in the above-mentioned high-speed stacker, the present application proposes a new high-speed stacker. Summary of the invention

[0031] Reference Figure 1-5 , an embodiment of the present application is proposed, and the high-speed stacker described in this embodiment includes:

[0032] A lower cross beam 10 is horizontally arranged along the left-right direction, and a walking mechanism 20 is installed on the lower cross beam 10;

[0033] Two columns 30 are vertically mounted on the walking mechanism 20.

[0034] A cargo platform 40 is disposed between two upright posts 30, wherein upper pulleys 50 are respectively disposed on the left and right sides of the upper end of the cargo platform 40, and lower pulleys 60 are respectively disposed on the left and right sides of the lower end;

[0035] A transmission belt 70 is provided on each of the columns 30 , one end of the transmission belt 70 is connected and fixed to the upper end of the column 30 , and the other end of the transmission belt 70 is passed through the upper pulley 50 on the same side, the upper end of the column 30 , the driving wheel assembly 80 , the lower end of the column 30 , and the lower pulley 60 in sequence, and then is connected and fixed to the lower end of the column 30 .

[0036] In this embodiment, the end of the transmission belt 70 connected and fixed to the upper end of the column 30 is defined as the first end, and the end of the transmission belt 70 connected and fixed to the lower end of the column 30 is defined as the second end. Referring to the accompanying drawings, two fixed wheels 301 are respectively provided at the upper and lower ends of each column 30. The second end of the transmission belt 70 moves downward and passes around the upper pulley 50 upward, passes around the two fixed wheels at the upper end of the column 30 and then passes around the driving wheel assembly 80 downward. The second end of the transmission belt 70 then passes around the two fixed wheels at the lower end of the column 30 and then moves upward, passes around the lower pulley 60 and is connected and fixed to the lower end of the column 30.

[0037] When the transmission belt 70 passes around the driving wheel assembly 80, the transmission belt 70 is divided into two sections by the driving wheel assembly 80. When the driving wheel assembly 80 rotates to transport the transmission belt 70, the lengths of the two sections of the transmission belt 70 can be changed simultaneously and synchronously, so that the lengths of the two sections of the transmission belt 70 are adjusted synchronously, and the heights of the upper and lower ends of the cargo platform 40 are synchronously controlled through the transmission belt 70.

[0038] Compared with the prior art, the lifting and lowering of the cargo platform 40 is controlled by the transmission belt 70, and the transmission is smooth, without impact and noise, and can be suitable for high-speed transmission; and the transmission belt 70 has low maintenance cost, low loss and long service life.

After the other end of the transmission belt 70 passes around the upper end of the column 30, it passes through the top of the driving wheel 802 and between the limiting pulleys 803 above it and passes around the driving wheel 802, and then passes through the bottom of the driving wheel 802 and between the limiting pulleys 803 below it.

[0040] In the present application, the two limiting pulleys 803 are used to tension the transmission belt 70 on the driving wheel 802. After the wheel driving motor 801 drives the driving wheel 802 to rotate, the driving wheel 802 drives the pulley to move. For example, when the driving wheel 802 rotates to shorten the length between it and the first end and drive the cargo platform 40 to rise, the driving wheel 802 drives the length between it and the second end to increase synchronously for the cargo platform 40 to rise.

[0041] In this embodiment, the cargo platform 40 includes two platform base plates 401, and the two platform base plates 401 are vertically arranged on the side where the two columns 30 are close to each other.

[0042] As shown in the accompanying drawings, four forks are arranged on the two carrier substrates 401, and the four forks can work synchronously to pick up multiple goods at the same time.

[0043] The two transmission belts 70 are respectively raised and lowered synchronously with the two stage base plates 401 , thereby driving the forks 403 on the stacking mounting plate 402 to be raised and lowered through the two stage base plates 401 .

[0044] Preferably, a rotatable limiting wheel 404 is further provided on the carrier substrate 401 , and the wheel surface of the limiting wheel 404 is in rolling contact with the column 30 to ensure stable lifting and lowering of the carrier substrate 401 .

[0045] Furthermore, the column 30 is provided with a vertically distributed guide groove 405 , and the stage substrate 401 is also provided with a guide wheel 406 , and the guide wheel 406 is inserted into the guide groove 405 and can slide along the guide groove 405 .

[0046] In this embodiment, the walking mechanism 20 includes a lower beam 201 and two walking wheel assemblies 202. The lower beam 201 is horizontally arranged and connected and fixed to the lower ends of the two columns 30. The two walking wheel assemblies 202 are respectively fixedly installed at both ends of the lower beam 201 and can walk along the lower cross beam 10.

[0047] Specifically, the travel wheel assembly 202 includes a travel drive motor 2021 and a travel wheel body 2022 . The travel drive motor is fixedly mounted on the lower beam 201 , and the travel wheel body is fixedly mounted on the output shaft of the travel drive motor.

[0048] In this embodiment, the walking mechanism 20 also includes a plurality of guide wheel assemblies 203, and the plurality of guide wheel assemblies 203 are arranged in sequence along the length direction of the lower beam 201.

The vertical track guide wheel 2032 extends into the C-shaped steel 101 and can roll along the groove on the C-shaped steel 101, so that the lower beam 201 can stably walk along the lower cross beam 10.
