[0053] In the logistics industry, boxed materials are a common form of incoming material. Boxed materials are typically stacked on pallets for easy storage and handling. Manual depalletizing is often used during the turnover or shipment of boxed materials. This method is labor-intensive, inefficient, and carries high labor costs. In recent years, with the widespread adoption of industrial automation, there has been a growing demand for mechanized and automated depalletizing, as well as for simpler and more cost-effective depalletizing machines.

[0054] The present invention creatively provides a depalletizer, comprising a frame, a lifting mechanism, a clamping mechanism and a driving mechanism, wherein the frame comprises two side supports arranged opposite to each other; the lifting mechanism is provided with two groups, and the two lifting mechanisms are provided in a one-to-one correspondence with the two side supports; each lifting mechanism group comprises a slide rail and a slider, the slide rail is provided on the corresponding side support, and the slider is slidably provided on the slide rail; the clamping mechanism is provided with two groups, and the two clamping mechanisms are provided in a one-to-one correspondence with the two lifting mechanisms; the clamping mechanism is rotatably provided on the corresponding slider; the driving mechanism comprises a driving member, the driving member is formed with two driving parts, the two driving parts are provided in a one-to-one correspondence with the two clamping mechanisms, and the driving parts and the corresponding clamping mechanisms are connected by a traction rope;

[0055] When the depalletizer is in a non-working state, both traction ropes are loosened, and the two clamping mechanisms cannot apply a clamping force to the material box; when the depalletizer is in a first working state, both traction ropes are tightened, and the traction ropes can lead the clamping mechanisms to rotate relative to the corresponding sliders, so that the two clamping mechanisms are close to each other and can apply a clamping force to the material box; when the depalletizer is in a second working state, both traction ropes are tightened, and the traction ropes can lead the corresponding clamping mechanisms, sliders and material boxes to move up and down together; the structure is simple, the depalletizing efficiency is high and the cost is low.

[0056] like Figures 1 to 2c As shown, this embodiment provides a depalletizer, comprising:

[0057] The frame 1 includes two side brackets 11 arranged opposite to each other; an accommodating space is formed between the two side brackets 11, and the accommodating space is used to accommodate the material box;

[0058] The lifting mechanism 2 is provided with two groups, and the two groups of lifting mechanisms 2 are provided in a one-to-one correspondence with the two side brackets 11; each group of lifting mechanisms includes a slide rail 211 and a slider 212, the slide rail 211 is provided on the corresponding side bracket 11, and the slider 212 is slidably provided on the slide rail 211;

[0059] The clamping mechanism 3 is provided with two groups, and the two groups of clamping mechanisms 3 are provided in a one-to-one correspondence with the two groups of lifting mechanisms 2; the clamping mechanism 3 is rotatably provided on the corresponding slider 212;

[0060] The driving mechanism 4 includes a driving member 41 having two driving portions 413 . The two driving portions 413 are provided in a one-to-one correspondence with the two groups of clamping mechanisms 3 , and the driving portions 413 and the corresponding clamping mechanisms 3 are connected by a traction rope 42 .

[0061] The depalletizer is provided with a non-working state, a first working state and a second working state;

[0062] like Figure 3a to Figure 3b As shown, when the depalletizer is in a non-working state, the two traction ropes 42 are loosened, and the two clamping mechanisms 3 cannot apply a clamping force to the material box;

[0063] like Figures 4a to 4b As shown, when the depalletizer is in the first working state, the two traction ropes 42 are tightened, and the traction ropes 42 can rotate the clamping mechanism 3 relative to the corresponding slider 212, so that the two clamping mechanisms 3 are close to each other and can apply a clamping force to the material box;

[0064] When the depalletizer is in the second working state, both traction ropes 42 are tightened, and the traction ropes 42 can move up and down with the corresponding clamping mechanism 3, the slider 212 and the material box;

[0065] A driving member 41 drives the clamping mechanism 3 to rotate relative to the corresponding slider 212, and the two clamping mechanisms 3 move closer to each other to clamp the material box; a driving member 41 drives the clamping mechanism 3 and the corresponding slider 212 to move up and down together to lift or lower the material box; the clamping mechanism 3 rotates relative to the corresponding slider 212 under the action of gravity, and the two clamping mechanisms 3 move away from each other to release the material box;

[0066] The depalletizer of the present application has a simple structure and can be quickly assembled according to the site and material box size; when depalletizing a material box, the material box is placed in the storage space, and the driving mechanism is controlled to move to complete the depalletizing function with high depalletizing efficiency; compared with traditional depalletizers, the present application is low in price, has a short development cycle, and has good stability and versatility.

[0067] To address the problem that the clamping mechanism 3 cannot clamp the material box due to an unreasonable structural design and weak clamping force, this embodiment proposes that each clamping mechanism 3 includes a lever 31 and a clamping claw 32. The lever 31 includes a first connecting portion 313, a rotating portion 314, and a second connecting portion 315, which are arranged in sequence. The first connecting portion 313 and the corresponding driving portion 413 are connected by a traction rope 42. The rotating portion 314 is rotatably arranged on the slider 212. The second connecting portion 315 is provided with a clamping claw 32.

[0068] like Figure 3a to Figure 3b As shown, when the depalletizer is in a non-working state, the horizontal distance between the two clamping jaws 32 is a first distance, and the two clamping jaws 32 cannot apply a clamping force to the material box;

[0069] like Figures 4a to 4b As shown, when the depalletizer is in the first working state and the second working state, the horizontal distance between the two clamping jaws 32 is a second distance, and the two clamping jaws 32 can apply a clamping force to the material box;

[0070] The first distance is greater than the second distance.

[0071] Furthermore, the lever 31 includes a rod segment A 311 and a rod segment B 312. The rod segment A 311 and the rod segment B 312 are connected, and a rotating portion 314 is formed at the connection between the rod segment A 311 and the rod segment B 312. The end of the rod segment A 311 away from the rod segment B 312 is a first connecting portion 313, and the end of the rod segment B 312 away from the rod segment A 311 is a second connecting portion 315.

[0072] When the traction rope 42 is loosened, the two levers 31 rotate under the action of gravity, causing the two clamping jaws 32 to move away from each other; when the traction rope 42 is tightened, the two levers 31 rotate under the action of the tension, causing the two clamping jaws 32 to move closer to each other;

[0073] For example, when the traction rope 42 is loosened, under the action of gravity, one lever 31 rotates clockwise and the other lever 31 rotates counterclockwise, causing the two clamping jaws 32 to move away from each other; when the traction rope 42 is tightened, under the action of tension, one lever 31 rotates clockwise and the other lever 31 rotates counterclockwise, causing the two clamping jaws 32 to move closer to each other.

[0074] Preferably, the A rod segment 311 and the B rod segment 312 are both linear structures, and the angle α between the extension direction of the A rod segment 311 and the extension direction of the B rod segment 312 satisfies: 45°≤α≤90°.

[0075] To address the problem of the inability to lift the material box due to an unreasonable structural design of the lifting mechanism 2, this embodiment proposes that two sets of lifting mechanisms 2 are arranged relative to each other along the first direction 61, and each set of lifting mechanisms 2 includes two sliding assemblies 21, and the two sliding assemblies 21 are arranged relative to each other along the second direction 62; each sliding assembly 21 includes a slide rail 211 and a slider 212;

[0076] Each clamping mechanism 3 further includes a rotating shaft 33 connected to a rotating portion 314 , and disposed between the two sliding assemblies 21 ; one end of the rotating shaft 33 is rotatably disposed on the slider 212 of one sliding assembly 21 , and the other end of the rotating shaft 33 is rotatably disposed on the slider 212 of the other sliding assembly 21 ; wherein the first direction 61 and the second direction 62 are perpendicular;

[0077] Specifically, the two groups of lifting mechanisms 2 include a first sliding assembly and a second sliding assembly arranged opposite to each other, one rotating end of which is rotatably set on the slider 212 of the first sliding assembly, and the other end of the rotating shaft 33 is rotatably set on the slider 212 of the second sliding assembly; when the traction rope 42 is loosened and under the action of gravity, or when the traction rope 42 is tightened, the rotating shaft 33 can rotate relative to the slider 212 of the first sliding assembly and the slider 212 of the second sliding assembly; when the traction rope 42 is tightened, the rotating shaft 33, the slider 212 of the first sliding assembly and the slider 212 of the second sliding assembly can move up and down together.

[0078] To address the issue of the clamping structure being rotatably arranged relative to the slider 212, this embodiment proposes that each clamping mechanism 3 includes two levers 31. The first connecting portions 313 of the two A rod segments 311 are connected by a connecting member 34, and the connecting member 34 and the corresponding driving portion 413 are connected by a traction rope 42. The second connecting portions 315 of the two B rod segments 312 are connected by a clamping claw 32, and the two rotating portions 314 are connected by a rotating shaft 33.

[0079] Preferably, the connecting member 34 is formed with a protrusion 341, which is a spherical structure and is connected to the traction rope 42; the A rod segment 311, the B rod segment 312 and the rotating shaft 33 are all detachably connected, the A rod segment 311 and the connecting member 34 are detachably connected, and the B rod segment 312 and the clamping claw 32 are detachably connected; the connecting member 34 and the clamping claw 32 are both lean tubes for easy replacement;

[0080] By adjusting the strength of the lever 31, material boxes of different weights can be clamped; by adjusting the length of the lever 31, material boxes of different volumes can be clamped; specifically, by adjusting the length of the B rod section 312, material boxes of different volumes can be clamped;

[0081] Preferably, a groove is formed on the side wall of the material box. When the clamping jaws 32 are embedded in the groove, the two clamping jaws 32 can clamp the material box.

[0082] To address the problem of instability when the traction rope 42 rotates and moves up and down with the clamping mechanism 3, this embodiment proposes that the depalletizer further includes a rotatable guide wheel mechanism 5, and the guide wheel mechanism 5 is provided with two groups, and the two groups of guide wheel mechanisms 5 are provided in a one-to-one correspondence with the two groups of clamping mechanisms 3; the guide wheel mechanism 5 and the driving member 41 are both provided above the clamping mechanism 3;

[0083] The traction rope 42 is wound around the corresponding guide wheel mechanism 5, and one end of the traction rope 42 is connected to the corresponding driving part 413, and the other end of the traction rope 42 is connected to the corresponding clamping mechanism 3; the guide wheel mechanism 5 can reduce the friction between the traction rope 42 and the frame 1, making it more labor-saving and reliable when the driving part 41 tightens and loosens the traction rope 42.

[0084] Furthermore, each side support 11 includes a side column 111 and a side crossbeam 112. There are two side columns 111, which are spaced apart. The side crossbeam 112 is disposed on top of the two side columns 111 and connects the two side columns 111. The lifting mechanism 2 is disposed between the two side columns 111, and the clamping mechanism 3 is disposed between the two sliding assemblies 21. The side crossbeam 112 extends along the second direction 62.

[0085] The frame 1 further includes a top support 12, which includes a first top crossbeam 121 and a second top crossbeam 122 spaced apart from each other; the first top crossbeam 121 and the second top crossbeam 122 both extend along the first direction 61, and are both connected between the two side crossbeams 112; a driving member 41 is provided on the first top crossbeam 121;

[0086] Each guide wheel mechanism 5 includes a plurality of guide wheels, including at least a first guide wheel 51, a second guide wheel 52, and a third guide wheel 53; the first guide wheel 51 is disposed on the second top crossbeam 122 and is located close to the corresponding drive unit 413; the second guide wheel 52 is disposed at the connection between the second top crossbeam 122 and the side crossbeam 112; and the third guide wheel 53 is disposed on the side crossbeam 112 and is located close to the corresponding clamping mechanism 3.

[0087] The traction rope 42 is sequentially wound around the corresponding first guide wheel 51, the second guide wheel 52 and the third guide wheel 53;

[0088] The axis of the first guide wheel 51 is parallel to the axis of the second guide wheel 52 , and the axis of the first guide wheel 51 is perpendicular to the axis of the third guide wheel 53 ;

[0089] Preferably, the position of the first guide wheel 51, the position of the second guide wheel 52, and the position of the third guide wheel 53 are all adjustable; by adjusting the position of the first guide wheel 51, the position of the second guide wheel 52, and the position of the third guide wheel 53, the winding direction of the traction rope 42 can be changed, so as to more reasonably arrange the traction path of the traction rope 42; or,

[0090] The axial extension direction of the first guide wheel 51, the axial extension direction of the second guide wheel 52 and the axial extension direction of the third guide wheel 53 can all be adjusted; by adjusting the axial extension direction of the first guide wheel 51, the axial extension direction of the second guide wheel 52 and the axial extension direction of the third guide wheel 53, the winding direction of the traction rope 42 can be changed, which facilitates a more reasonable arrangement of the traction path of the traction rope 42.

[0091] In order to solve the problem of complex structure of the driving member, this embodiment proposes that the driving member 41 is a cylinder, which includes a cylinder body 411 and a pneumatic rod 412. One end of the pneumatic rod 412 is telescopically arranged in the cylinder body 411, and the other end of the pneumatic rod 412 is formed with two driving parts 413; when the pneumatic rod 412 is extended, the traction rope 42 can be loosened, and under the action of gravity, the two clamping jaws 32 are opened. At this time, the material box can be placed between the two clamping jaws 32 or the destacker can be moved to the material box and the material box can be placed between the two clamping jaws 32; when the pneumatic rod 412 is retracted, the traction rope 42 can be tightened, and the two clamping jaws 32 can clamp the material box between the two clamping jaws 32; when the pneumatic rod 412 continues to retract, the traction rope 42 can carry the clamping jaws 32, the slider 212 and the material box up and down, so that the material box is separated from the material box stack, thereby destacking the material box, and finally achieving the desired effect;

[0092] Specifically, the air inlet and the air outlet of the cylinder 411 are connected to an air pipe, and an air valve is connected in series to the air pipe. The opening or closing of the air valve is controlled to extend or retract the air pressure rod 412, thereby loosening or tightening the traction rope 42;

[0093] The driving member 41 may also be a motor, a hydraulic cylinder or other suitable driving member 41 .
