Description

Technical Field

[0001] The utility model relates to the overturning of a whole stack of corrugated cardboards in the process of corrugated cardboard logistics, in particular to a full-automatic online stack overturning machine for corrugated cardboards. Background Art

[0002] Five-layer corrugated paperboards need to be touched, that is, pre-indented according to the position of the folding line of the upper and lower flaps of the paperboard. Since the five-layer corrugated paperboard is very thick (up to 8-10mm), and the folding line of the flap is perpendicular to the pit of the corrugated paperboard, the upper and lower flaps of the corrugated paperboard can only be folded after indentation, and the indentation method is to use the mother-and-child grooves for collision, so the indentation operation is also called touch in the industry.

[0003] When corrugated cardboard is fed to the paper feeding table of the printing press through the fully automatic logistics system, logistics is generally carried out in "stacks". Because some products need to touch the line, while some products do not. For example, three-layer cardboard color printing carton can be creased by die cutting because the cardboard is relatively thin, while five-layer kraft paper boxes only need to be directly creased by touching the line. The crease of the touch line is always made from the front, so the face paper of the cardboard is facing up. After the cardboard stack that needs to touch the line is delivered to the place, the automatic feeder can directly send it to the paper feeding table for printing. If the cardboard stack that is delivered does not need to touch the line, the cardboard will be facing downward. Therefore, the entire stack of cardboard must be turned 180° before it can be sent to the paper feeding table for printing. In order to realize fully automatic loading, it is necessary to flip the whole stack of cardboard that does not need to touch the line 180° in advance and then transport it to the entrance of the feeding machine. Therefore, in order to realize fully automatic unmanned production of corrugated cardboard, it is very necessary to design a stacking machine that can flip the cardboard stack that needs to be turned over online during the corrugated cardboard logistics process. Summary of the invention

[0004] The utility model aims to provide a fully automatic online corrugated cardboard stacking machine to meet the fully automatic unmanned production of corrugated cardboard.

[0005] In order to achieve the above purpose, the utility model can adopt the following technical solutions:

[0006] The fully automatic online corrugated cardboard stacking machine described in the utility model comprises left and right supporting columns arranged at intervals, and a turning frame composed of left and right side plates, an upper movable pressing plate and a lower fixed bottom plate, the left and right side plates of the turning frame are respectively hinged to the left and right supporting columns, and driven by a turning power source to turn 180 degrees; the middle part of the upper movable pressing plate driven by a lifting mechanism to move up and down is provided with left and right through holes at intervals, the bottoms of the left and right back plates inserted in the left and right through holes are fixed to the lower fixed bottom plate, the left and right bottom supporting plates are horizontally arranged on the lower fixed bottom plate at the bottom of the left and right back plates, and the left and right stacking plates are horizontally arranged on the upper movable pressing plate corresponding to the positions of the left and right through holes.

[0007] When the printing press is operating, for cardboard stacks that do not need to touch the line, the fully automatic logistics system can first transport them to the left and right bottom pallets of the stacker. After being automatically controlled and flipped 180° by the flipping frame, they can enter the loading system of the printing press for logistics. It does not affect the normal operation of the loading machine, and fully meets the needs of fully automated operation of corrugated cardboard.

[0008] The flip frame of the present application is approximately a rectangular frame structure.

[0009] The power source used in the present application includes a flip motor and a reduction gear driven by the flip motor, and the flip frame shaft fixed on the left and right side plates is key-connected with the inner hole of the reduction gear.

[0010] The lifting mechanism used in the present application includes an upper movable pressure plate motor respectively arranged on the left and right side plates and a worm driven by the motor to rotate. The worm wheels respectively arranged at the bottom of the left and right lifting screws arranged in the left and right side plates are meshed with the corresponding worms, driving the upper movable pressure plate whose two ends are respectively screwed on the left and right lifting screws to rise or fall.

[0011] In order to achieve seamless connection with the fully automatic logistics system, a paper feed roller path and a paper discharge roller path are respectively arranged on both sides of the supporting column. The paper feed roller path and the paper discharge roller path are mirror-image settings with the same structure, and gaps with the same width as the left and right bottom support plates or the left and right palletizing plates are respectively arranged in the middle; since the widths of the left and right bottom support plates or the left and right palletizing plates are the same, the widths of the gaps arranged in the middle of the paper feed roller path and the paper discharge roller path are also the same.

[0012] The utility model has the advantages of simple structure and convenient operation. It is placed in the automatic logistics system in front of the feeder, and the cardboard stack that needs to be turned over is turned 180 degrees before entering the feeder, which does not affect the normal operation of the feeder and can meet the needs of full-automatic operation.

When working, the upper movable platen motor 10.2 is started, and the right lifting screw 12.2 is driven to rotate through the worm wheel pair, and the upper movable platen 2.3 whose two ends are respectively screwed on the left and right lifting screws can rise or fall.

[0022] During operation, the paper feed roller 6 is connected with the automatic paper feed area logistics roller 01 of the automatic logistics system, and the paper discharge roller 7 is connected with the paper discharge area logistics roller 02.

[0023] When the utility model is used, it is placed at the front end of the full-automatic feeder SLJ, such as Figure 2 As shown, the cardboard stack A that needs to be turned over is transported by the logistics system through track II (the feeding channel that needs to be turned over) to the logistics roller 01 in the paper feeding area, and after being turned over by the online stacker of the utility model, it enters the material preparation buffer zone, and is then sent to the upper paper table of the printing press by the fully automatic loader SLJ for printing; the cardboard stack B that does not need to be turned over is directly transported by the logistics system through track I (the straight-through feeding channel that does not need to be turned over) to the material preparation buffer zone, and is sent to the upper paper table of the printing press by the fully automatic loader SLJ for printing.

[0024] The action process of the utility model is as follows:

The left upper moving platen motor and the right upper moving platen motor 10.2 are started in reverse, the upper moving platen 2.3 is released, the left stacking plate 5.1 and the right stacking plate 5.2 fall down, and the cardboard stack falls onto the paper discharge roller 7 synchronously;

[0033] 9. The output roller drive motor 7.1 starts, driving the paper output roller 7 to deliver the cardboard stack to the paper output area logistics roller 02. The entire flipping operation is completed. The flipped cardboard stack enters the material preparation buffer and is then sent to the paper loading table of the printing press by the fully automatic loader SLJ for printing.
