[0031] The distance between the axis of the support wheel 27 and the axis of the groove wheel shaft 24 is a, and the spacing between the axes of adjacent groove wheel shafts 24 is That is Figure 6 As shown in FIG. 1 , the angle β between the line connecting the axis of the supporting wheel 27 to the axis of the groove wheel shaft 24 and the line connecting the axis of the adjacent groove wheel shafts 24 is 60 degrees.

[0032] There are two roller conveyors 2 , and the screw nut mechanism 3 is arranged in parallel between the two roller conveyors 2 .

At the same time, the second pin wheel 17 is not provided on the lowest sprocket shaft 23. The lowest groove wheel shaft 24 is driven by the groove wheel shaft above it through the second chain 30. This is to avoid mutual interference with the horizontal transmission action.

[0037] The working principle of the accompanying carrying plate horizontal conveying mechanism in the present invention is as follows:

[0038] When the accompanying carrier plate 1 is stacked, the reduction motor starts to work, driving the screw nut mechanism 3. The slider on the screw nut mechanism drives the push mechanism 4 to move toward the accompanying carrier plate lifting mechanism. The grab hook 7 on the push mechanism 4 is always caught on the grab hook groove 29 of the accompanying carrier plate 1, driving the accompanying carrier plate 1 to move into the stacking station. When it reaches the designated stacking station, the Figure 3 The cross wheel 10 in the roller 2 touches the lever 9 fixedly installed on the side of the roller 2, and the cross wheel 10 rotates 90 degrees, driving the first bevel gear to rotate 90 degrees as well. The first bevel gear drives the second bevel gear 14 meshing with it to rotate 360 ​​degrees through a 1:4 transmission ratio, and the second bevel gear 14 drives the first pin wheel 13 coaxially fixedly connected to rotate 360 ​​degrees. When the first pin wheel 13 rotates 360 degrees, the first pin wheel 13 drives the four-groove groove wheel 12 to rotate 90 degrees, and the four-groove groove wheel 12 drives the grab hook 7 coaxially connected to it to rotate 90 degrees around the axis, so that the grab hook 7 is separated from the grab hook groove 29, completing the return action of the grab hook 7. At the same time, a travel switch is also provided on the accompanying carrier plate horizontal conveying mechanism. When the accompanying carrier plate 1 moves to the accompanying carrier plate lifting mechanism, the slider on the lead screw nut mechanism touches the travel switch to stop the reduction motor. The stacking action is completed. When the stacking action is completed, a photoelectric sensor is provided on the shelf to notify the system computer that this station is "not empty".

[0039] When the accompanying carrier plate is taken, the reduction motor starts to work, the pusher mechanism 4 starts to move, the cross wheel 10 touches the lever 9 fixedly installed on the side of the roller 2, and the grab hook 7 rotates 90°, so that the grab hook 7 grabs the two grab hook grooves 29 on the accompanying carrier plate, and the pusher mechanism 4 drives the accompanying carrier plate 2 to move outward together. The computer is notified through the sensor that the crane has loaded the vehicle, and at the same time, the storage rack recognizes that the accompanying carrier plate 1 displays "empty" through the photoelectric sensor.

[0040] The working principle of the accompanying load plate lifting mechanism is as follows:

[0041] When the accompanying carrier plate is lifted, the motor starts to work, driving the first sprocket and the first chain 8 to rotate, the first sprocket drives all the sprocket shafts to rotate, the second pin wheel 17 on the sprocket shaft rotates, the second toggle pin 21 of the second pin wheel 17 rotates, the second toggle pin 21 fits into the pin groove of the six-groove groove wheel 18 on the groove wheel shaft 24, and drives the six-groove groove wheel 18 to rotate, the second toggle pin 21 rotates over 240 degrees, and the six-groove groove wheel 18 rotates continuously by 120 degrees. The rotation of the six-groove groove wheel 18 drives the two planetary wheel brackets 19 on the groove wheel shaft to rotate, and the planetary wheel bracket 19 rotates 120 degrees to lift the accompanying carrier plate 1. When the lifting action rises to the upper limit of the height of the planetary wheel bracket 19, the support wheel 27 of the planetary wheel bracket 19 continues to rotate and disengage, and the upper planetary wheel bracket 19 contacts the carrier plate and continues to lift.

[0042] The operating principle of the six-slot sheave 18:

[0043] The six-groove groove wheel 18 has six pin grooves, each of which is spaced 60 degrees apart, and a concave arc surface is provided between the pin grooves, which can be in close contact with the side surface of the second cam on the second pin wheel 17. The second pin wheel 17 is provided with two second toggle pins 21 spaced 120 degrees apart.

[0044] When the motor is not running, the support wheel 27 of the planetary wheel support 19 supports the accompanying carrier plate 1, and the state of the six-slot groove wheel 18 is as follows: Figure 7 As shown in , the side surface of the second cam 20 on the second pin wheel 17 is completely in contact with an arc surface of the six-groove groove wheel 18. At this time, the accompanying carrier plate 1 is stationary, and a vertical force is applied to the planetary gear support 18, generating torque on the groove wheel shaft 24. Because the six-groove groove wheel 18 is in contact with the side arc surface of the second pin wheel 17, the force of the six-groove groove wheel 18 on the second cam 20 is vertically upward, and the second cam 20 and the second pin wheel 17 cannot be displaced in the vertical direction. Therefore, the six-groove groove wheel 18 cannot rotate, and the six-groove groove wheel 18 and the second pin wheel 17 are stuck to each other, and the accompanying carrier plate 1 will not fall. When the accompanying carrying plate 1 is lifted, the second pin wheel 17 rotates, and the first second driving pin 21 rotates to the corresponding groove of the six-groove groove wheel 18, and begins to cooperate and enter the pin groove of the six-groove groove wheel 18, generating a tangential force on the pin groove wall of the six-groove groove wheel 18, driving the six-groove groove wheel 18 to rotate, and the six-groove groove wheel 18 drives the planetary gear support 19 to lift the accompanying carrying plate 1.

[0045] In conclusion, the above is only a preferred embodiment of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the patent of the present invention.
