[0029] The technical solution of the present invention is further explained with reference to the accompanying drawings.

[0030] like Figure 1 The figure shows a device for shaping material bin stacks, comprising a frame assembly 31, side guide assemblies 33, and a lifting power assembly 34. The frame assembly 31 has a passageway for accommodating material bins. A conveyor is provided in the passageway to transport the stacked material bins in and out. A push rod is mounted on the right side of the conveyor, and a guide plate is mounted on the left side. The push rod pushes the stacked material bins and pallets to position them. A stopper is provided at the end of the conveyor.

[0031] The stack of shaped bins and their pallets are transported on an external conveyor. The pneumatic push rods on the conveyor push the pallets against the guide plates on one side of the conveyor, positioning the bin stack in one direction and preparing it for entry into the shaping equipment. Before entering the shaping equipment, external sensors on 6 to 10 levels screen the height of the bin stack. A non-triggered condition is considered an entry condition; otherwise, the bins are transported back to the previous process. After entering the shaping equipment and reaching the conveyor terminal stop, the lateral positioning plate assembly is activated to position the bin stack and pallet. The lifting power assembly then activates the side guide assembly, effectively separating the bin stack, automatically centering it, and accurately stacking it. The stacked bins are then conveyed to the next process.

[0032] The device includes a positioning drive assembly 32, and a positioning rod is provided opposite the positioning drive assembly 32. The positioning drive assembly 32 pushes the material box to be shaped from left to right against the positioning rod to obtain positioning.

[0033] like Figure 2 As shown, the lifting power assembly 34 lifts the side guide assembly 33 layer by layer, and drives the material box to separate layer by layer, and then fall down layer by layer. The side guide assembly includes a support pin 3312: the cylindrical surface of the support pin 3312 acts on the inclined edge of the side of the material box, so that its position is automatically centered when the material box falls.

[0034] Frame assembly 31 as Figure 3 As shown, they are all constructed from welded square and rectangular tubes connected by bolts, providing a framework support for the remaining functional components. The frame assembly 31 is equipped with a sensor to measure the height of the bin stack; the equipment is also equipped with a height detection switch 352, front and rear limit detection switches 353, and extreme position detection switches 354, 354, and 355.

[0035] like Figure 4 、 Figure 12 As shown, the positioning drive assembly 32 includes a laterally movable positioning plate assembly 321; a linear guide assembly 322; a moving slider assembly B323; a bracket welding assembly 324; a lifting motor 325; a lifting spindle 326; a lifting cam assembly 327; and a moving slider assembly A328; the laterally movable positioning plate assembly 321 is engaged with the linear guide assembly through the moving slider assembly; the lifting cam assembly 327 is installed on the bracket welding assembly 324, the lifting motor 325 drives the lifting spindle 326 to rotate, and the lifting cam assembly 327 is converted through the lifting spindle 326, and the laterally movable positioning plate assembly 321 performs reciprocating linear motion, and the linear guide assembly 322 provides linear guidance for the laterally movable positioning plate assembly 321.

[0036] The laterally movable positioning plate assembly 321 is mainly used for lateral positioning of material box stacking and pallet.

[0037] The linear guide rail assembly 322 mainly provides linear guidance for the lateral movement of the positioning plate assembly 321 .

[0038] The movable slider assembly B323 and the movable slider assembly A328 mainly provide an installation and connection basis for the laterally movable positioning plate assembly 321.

[0039] The bracket welding assembly 324 provides a framework foundation for the lifting motor 325 , the lifting spindle 326 , and the lifting cam assembly 327 .

[0040] The lifting motor 325 provides power for laterally moving the positioning plate assembly 321 .

[0041] The lifting main shaft 326 and the lifting cam assembly 327 convert the rotational motion of the main shaft into the linear motion of the cam assembly, providing reciprocating linear motion for the laterally moving positioning plate assembly 321.

[0042] The side guide assembly 33 includes a side positioning assembly 331, a floating pin mechanism 332, a guide shaft 333 and a bearing 334; the guide shaft 333 is installed between the bearings 334, allowing several side positioning assemblies 331 to move up and down on the guide shaft 333, and the floating pin mechanism 332 is located between the side positioning assemblies 331 to adjust the stacking height.

[0043] like Figure 5 As shown, the side positioning assembly 331 includes: a top side plate 3311 that provides an installation bearing platform for other components of the side positioning assembly 331; a limit block 3313 is a cubic block that acts on the horizontal edge of the material box; a chain adjustment assembly 3314 is installed on the side positioning assembly and connected to the chain; a linear bearing 3315 cooperates with the guide shaft 333; and a counterweight block 3316 is installed on the outside of the side positioning assembly 331.

[0044] The side positioning assembly 331 can lift and separate the stack of bins and automatically center them, ensuring that the bins are correctly stacked when lowered.

[0045] The floating pin mechanism 332 is adapted to the stacking height of the material boxes, separating and stacking the materials layer by layer, and ensuring the consistency of the separation height of each layer of the material boxes.

[0046] The guide shaft 333 provides the correct linear motion direction for the separation and stacking of the bin stacks.

[0047] The seated self-aligning bearing 334 provides installation support for the guide shaft 333 and can correct its position deviation.

[0048] The floating pin mechanism 332 includes: a nut 3322 for adjusting the distance between the floating pin 3321 and the plate surface; and a locking nut 3323 for locking the nut 3322 .

[0049] Side positioning assembly 331 as Figure 6 As shown, it mainly includes: a) Top side plate 3311: provides an installation and bearing platform for other components of the side positioning component 331.

[0050] b) Support pin 3312: The cylindrical surface of the support pin acts on the inclined edge of the side of the material box to automatically align its position, such as Figure 10 、 Figure 11 shown.

[0051] c) Limit block 3313: The flat part of the limit block acts on the horizontal edge of the material box to ensure that the material box is stable and does not shake. Figure 10 、 Figure 11 shown.

[0052] d) Chain adjustment assembly 3314: This is an adjustable assembly that connects the side positioning assembly to the chain. By adjusting the nut, the screw moves up and down, thereby adjusting the chain tension.

[0053] e) Linear bearing 3315: cooperates with the guide shaft 333 to provide the correct linear motion direction for the separation and stacking of the bin stacks.

[0054] f) Counterweight 3316: Alleviates the deviation of the center of gravity of the side positioning assembly 331 when the loaded material box is lifted.

[0055] g) If Figure 7 As shown, the floating pin 3321 provides a motion connection for each side positioning assembly, so that the material box stack is separated and stacked layer by layer. The floating pin step is at a certain distance from the plate surface (10mm), so that when all the side panels 3311 are lifted and separated, the separation spacing of each layer of side panels is equal, thereby ensuring the high consistency of the material box separation.

[0056] h) Modify the hexagonal nut 3322 and rotate the modified nut to change the distance between the floating pin step and the plate surface, thereby adjusting the height of the material box separation layer. The modified flange surface can provide effective support for the floating pin 3321.

[0057] i) Tighten the thin nut and the modified nut to prevent them from loosening.

[0058] like Figure 8 As shown, the lifting power assembly 34 includes a lifting motor 341, a driving sprocket 342, a bearing 343, a driven sprocket 344, a lifting spindle 345, and a lifting chain 346. The lifting motor 341 drives the driving sprocket 342 to rotate, which in turn drives the driven sprocket 344 through the chain, thereby driving the lifting spindle 345 to rotate, transmitting power and rotational motion. The lifting chain 346 drives the side positioning assembly to rise or fall. The lifting spindle 345 is mounted on the bearing 343. A rotary encoder 356 is installed on the lifting spindle 345.

[0059] Control aspects such as Figure 9 As shown, before the material box enters the shaping equipment, it is tested by the overheight detection switch 351, and the absence of a signal is considered a condition for entering the equipment. After the equipment is shaped, the material box is tested by the overheight detection switch 352 and the front and rear limit detection switches 353 set on the material box stack, and the absence of a signal is used as the standard for judging the shaping pass. During the shaping process, the material box stack is pushed into position by the laterally movable positioning plate assembly, and its limit detection switch 354 ensures that the movement does not exceed the travel. The lateral positioning assembly moves up and down, and its limit detection switch 355 ensures that the movement does not exceed the travel. The rotary encoder 356 for the up and down movement of the lateral positioning assembly is used to control the lifting accuracy.
