The invention discloses a lifter for stacking box-shaped materials in batches from top to bottom for material boxing, which comprises a lifting device, a lifting device and a lifting device, wherein the lifting device comprises: the fixing base 20 can be fixed on the external beam through the mounting hole on the outer side. Fig. 1 shows the initial position of the various structures of the device. Fig. 2 shows the initial positions of the first transport carriage 1 and the second transport carriage 2. Starting the electric roller 10 in the first conveying trolley 1, conveying the first material 32 to the electric roller 10 through the conveying device 3 on one side of the first conveying trolley 1, and closing the electric roller 10 in the first conveying trolley 1. Then, a first motor 19 in the first conveying trolley 1 is started, the first motor 19 drives a first shaft rod 15 to rotate through a motor shaft, the first shaft rod 15 drives a baffle 17 and a gear 18 to rotate clockwise by 180 degrees, and the first motor 19 is turned off. The inner side of the baffle 17 contacts with one side of the stop block 8 close to the advancing direction, and the gear 18 drives the transmission plate 9 and the electric roller 10 to rotate through the end face gear 11, so as to drive the first material 32 to rotate by 90 degrees (at this time, the state is shown in fig. 7).

Then the electric trolley 7 in the first conveying trolley 1 is started, the electric trolley 7 drives the stop dog 8 to move towards the automatic stacking mechanism 4, the stop dog 8 pushes the baffle 17 to move, and then pushes the carrying mechanism 6 to move, and then carries the first material 32 to move towards the automatic stacking mechanism 4, so that the first material 32 is positioned at the bottom of the right side stacking plate 22, and then the electric trolley 7 is closed. The motorized roller 10 is located in the gap formed by the support plate 23, and the height of the motorized roller 10 is slightly larger than the support plate 23 (in this state, as shown in fig. 8 and 9).

Then, the second motor 31 is started, the second motor 31 drives the second shaft rod 30 and the connecting rod 28 to rotate through the motor shaft, and further drives the left stacking plate 21 and the right stacking plate 22 to move, the left stacking plate 21 and the right stacking plate 22 slide up and down in the fixing seat 20 through the limiting rod 27, wherein the left stacking plate 21 moves down, and the right stacking plate 22 drives the first material 32 to move up, so that the first material 32 is separated from the first conveying trolley 1. When the bottom ends of the left and right stacking plates 21, 22 are flush (the state at this time is shown in fig. 10), the second motor 31 is temporarily turned off.

The first motor 19 in the first conveying trolley 1 is started, so that the first shaft lever 15 drives the baffle 17 and the gear 18 to rotate 180 degrees anticlockwise, and the first motor 19 is turned off. At this time, the inner side of the baffle 17 contacts with one side of the stop block 8 close to the advancing direction, and the gear 18 drives the transmission plate 9 and the electric roller 10 to rotate by 90 degrees through the end face gear 11, so that the initial state is recovered. Then start electronic dolly 7 in the first transport trolley 1, electronic dolly 7 drives dog 8 and moves to the left side, and dog 8 promotes baffle 17 and moves, and then promotes and carry thing mechanism 6 and move, makes electronic roller 10 be close to conveyer 3 that corresponds with it, resumes initial position promptly, closes electronic dolly 7, waits to load next material. Meanwhile, when the first transport carriage 1 moves to the left and exceeds the left stacking plate 21, the second motor 31 is continuously started, so that the left stacking plate 21 and the right stacking plate 22 are continuously displaced for a certain distance and then closed (in this case, the state is shown in fig. 11). Meanwhile, during the process that the first transporting carriage 1 moves to the left, the second transporting carriage 2 loads the second material 33 in the same operation manner as the first transporting carriage 1, and when the left stacking plate 21 and the right stacking plate 22 are displaced to the position shown in fig. 11, the second transporting carriage 2 carries the second material 33 to move toward the automatic stacking mechanism 4 and transports the second material 33 to the bottom end of the left stacking plate 21 (in this case, the state is shown in fig. 12).

Then, the electric telescopic rod 25 on one side of the right stacking plate 22 is started to make the push plate 24 push the first material 32 to move to the second material 33 (at this time, the state is shown in fig. 13), and then the electric telescopic rod 25 drives the push plate 24 to move to the original position. The second motor 31 is then activated, causing the left stacking plate 21 to carry the second material 33 and the first material 32 upward, and the right stacking plate 22 downward. Similarly, when the bottom ends of the left and right stacking plates 21 and 22 are flush with each other, the second motor 31 is temporarily turned off, and the inner side of the shutter 17 of the second transport carriage 2 is brought into contact with the side of the stopper 8 close to the forward direction by the same operation as that of the first transport carriage 1, the electric rollers 10 are rotated by 90 degrees to return to the initial state, and the second transport carriage 2 is moved toward the corresponding transport device 3, that is, to return to the initial position. Meanwhile, when the second transport cart 2 moves to the right and exceeds the right stacking plate 22, the second motor 31 is continuously started, so that the left stacking plate 21 and the right stacking plate 22 are continuously displaced for a certain distance and then closed. And then the first conveying trolley 1 and the second conveying trolley 2 can continue to convey materials into the right stacking plate 22 and the left stacking plate 21 by the above operation flows, which is not described in detail below.

The first conveying trolley 1 carries the third material 34 to be located at the bottom end of the right stacking plate 22 (at this time, the state is shown in fig. 14), the electric telescopic rod 25 on one side of the left stacking plate 21 is started, the push plate 24 pushes the second material 33 and the first material 32 to be displaced onto the third material 34 (at this time, the state is shown in fig. 15), and then the electric telescopic rod 25 drives the push plate 24 to be displaced to the original position. The above process is repeated to stack the goods in a vertical row, and then the stacked goods are pushed into an external big box (not shown) from one side by an external pushing mechanism (not shown). The above process is repeated until the outer large box is full.
