DETAILED DESCRIPTION

[0052] The following will be combined with the specific implementation of the utility model to clearly and completely describe the technical solution in the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0053] like Figure 1-4 As shown, a tray disassembling mechanism of the utility model comprises a frame 1 and a linear conveyor 2, and also comprises a first lifting mechanism 3, a second lifting mechanism 4 and a clamping mechanism 5.

[0054] Among them, the frame 1 is a rectangular frame, and its main body is made of square tubes welded together. Two linear conveyors 2 are fixed on the top. The two linear conveyors 2 are parallel and are used to convey the pallet 8 in the horizontal direction. The linear conveyor 2 is connected to the loading mechanism of the subsequent processing equipment, and the pallet 8 is transported to the loading mechanism through the linear conveyor 2.

[0055] The first lifting mechanism 3 is arranged between the two linear conveyors 2 and fixedly arranged on the top of the frame 1. The output end of the first lifting mechanism 3 is used to support the side end of the pallet 8 to realize the positioning and conveying of the pallet 8. Specifically, before destacking, the pallet 8 is placed on the linear conveyor 2, and the output end of the first lifting mechanism 3 extends upward. The linear conveyor 2 conveys the pallet 8 toward the output end of the first lifting mechanism 3. When the side end of the pallet 8 contacts the output end of the first lifting mechanism 3, the conveying stops. After that, the output end of the first lifting mechanism 3 returns downward and leaves the side end of the pallet 8.

[0056] The second lifting mechanism 4 is arranged on one side below the first lifting mechanism 3 and is fixedly arranged on the frame 1, and is used for driving the clamping mechanism 5 to rise and fall; the clamping mechanism 5 has two clamping parts 501, and the two clamping parts 501 are symmetrically arranged on both sides of the frame 1, and are used for clamping the stacked trays 8 layer by layer from bottom to top; a truncated cone-shaped positioning part 502 is fixedly arranged on the opposite ends of the two clamping parts 501, and a positioning hole 801 is arranged at the side end of the tray 8 corresponding to the position of the positioning part 502, and the positioning part 502 is used to be inserted into the corresponding positioning hole 801.

[0057] When the stacked multi-layer pallet 8 is transported to the right position, the clamping mechanism 5 clamps the second-layer pallet 8 below. In the clamping state, the positioning portion 502 is inserted into the corresponding positioning hole 801. After clamping, the second lifting mechanism 4 drives the clamping mechanism 5 to rise, and the clamping mechanism 5 drives the second-layer pallet 8 and the above pallets 8 to rise, so that the first-layer pallet 8 below is alone on the linear conveyor 2. At this time, the pallet 8 on it is transported to the loading mechanism through the linear conveyor 2. After transportation, the second lifting mechanism 4 drives the clamping mechanism 5 to descend, so that the existing multi-layer pallet 8 falls back on the linear conveyor 2, and the above actions are repeated to destacker and transport layer by layer.

[0058] In order to improve the stability of the tray 8 when it is lifted, two positioning parts 502 are fixedly provided on the clamping part 501 , and correspondingly, two positioning holes 801 are provided on the side ends of the tray 8 .

[0059] Since the positioning portion 502 is in a truncated cone shape, the insertion and matching between the positioning portion 502 and the positioning hole 801 is convenient.

[0060] In the above structure, the first lifting mechanism 3 includes a lifting cylinder 31 and a limit plate 32, wherein the lifting cylinder 31 is fixedly arranged on the frame 1, and the limit plate 32 is fixedly arranged on the output shaft of the lifting cylinder 31; specifically, the limit plate 32 is an L-shaped plate structure, one end of which is fixed on the output shaft of the lifting cylinder 31, and the other end is used to support and position the side end of the tray 8.

[0061] The second lifting mechanism 4 includes a screw lift 41 and a bracket 42, wherein the screw lift 41 is vertically arranged, and one end of the screw lift 41 is fixedly arranged on the frame 1; the bracket 42 is welded in an I-shape by a square tube, and after welding, it is fixedly arranged on the output shaft of the screw lift 41, and the side end of the bracket 42 extends out of the frame 1 in the horizontal direction; one end of the clamping mechanism 5 is fixedly arranged on the top of the bracket 42; specifically, the bracket 42 is welded in an isosceles trapezoid shape by a square tube, and its two ends extend out of the side ends of the frame 1, and two screw lifts 41 are arranged side by side on the inner side of the bracket 42, the lower ends of the two screw lifts 41 are fixedly arranged on the frame 1, and the output ends are fixedly arranged on the bracket 42. When the screw lift 41 is working, its output shaft drives the bracket 42 to rise and fall, and the bracket 42 drives the clamping mechanism 5 to rise and fall.

[0062] In order to improve the stability of the bracket 42 during lifting and lowering, the second lifting mechanism 4 also includes a second slide rail 43 and a second slider 44, wherein the second slide rail 43 is vertically arranged, and two second slide rails 43 are respectively fixed on both sides of the frame 1, and a second slider 44 is slidably arranged on each second slide rail 43; the second slider 44 is fixed on the side of the bracket 42 away from the second slide rail 43; during lifting and lowering, the second slider 44 slides along the second slide rail 43.

[0063] The clamping mechanism 5 adopts a clamping structure, which includes a linear drive mechanism 51, wherein the linear drive mechanism 51 is horizontally arranged, and two linear drive mechanisms 51 are fixedly arranged on the top of the bracket 42; the two linear drive mechanisms 51 are symmetrically arranged on both sides of the spiral screw elevator 41, and the two linear drive mechanisms 51 correspond to the two clamping parts 501 one by one; the clamping part 501 is fixedly arranged on the output end of the corresponding linear drive mechanism 51; specifically, when the linear drive mechanism 51 is working, its output end drives the clamping part 501 to translate, so that the two clamping parts 501 perform a clamping action.

[0064] In the above structure, the linear drive mechanism 51 includes a translation cylinder 511, a first slide rail 512 and a first slider 513, wherein the translation cylinder 511 is horizontally arranged, and one end of the translation cylinder 511 is fixedly arranged on the bracket 42; the first slide rail 512 is parallel to the translation cylinder 511, and one first slide rail 512 is arranged on both sides of the translation cylinder 511; the two first slide rails 512 are fixedly arranged on the bracket 42, and a first slider 513 is slidably arranged on each first slide rail 512; the clamping part 501 is fixedly arranged on the top of the corresponding first slider 513, and the side of the clamping part 501 is fixedly connected to the output end of the corresponding translation cylinder 511; specifically, when the translation cylinder 511 is working, its output shaft drives the clamping part 501 to translate, and when translating, the first slider 513 slides on the first slide rail 512.

[0065] The two clamping parts 501 are easy to injure people during the clamping action, causing production accidents. To solve this problem, a protective cover 6 is set on the outside of each clamping part 501; the protective cover 6 is fixed on the frame 1, and a plurality of through holes 601 are set through the side of the protective cover 6 in the horizontal direction, so that the clamping part 501 is protected by the protective cover 6 to prevent injury.

[0066] In addition, in order to prevent material leakage during transportation, a cover plate 7 is arranged between the two linear conveyors 2, wherein the cover plate 7 is fixedly arranged on the inner side of the top of the frame 1; an avoidance hole 701 is vertically penetrated at the position corresponding to the first lifting mechanism 3 on the cover plate 7; the lifting cylinder 31 is arranged below the cover plate 7, and the lifting cylinder 31 drives the limit plate 32 to selectively penetrate the avoidance hole 701; specifically, when positioning is required, the lifting cylinder 31 drives the limit plate 32 to rise and pass through the avoidance hole 701. After positioning, the lifting cylinder 31 drives the limit plate 32 to pass through the avoidance hole 701 and then return to its position.

[0067] A method of using a disk disassembly mechanism of the utility model is as follows:

[0068] When depalletizing, the stacked multi-layer pallets 8 are transported to the linear conveyor 2, and the lifting cylinder 31 drives the limit plate 32 to rise into position. The linear conveyor 2 transports the pallet 8 toward the output end of the first lifting mechanism 3. When the side end of the pallet 8 contacts the output end of the first lifting mechanism 3, the transportation is stopped. After that, the lifting cylinder 31 drives the limit plate 32 to return downward and leave the side end of the pallet 8.

[0069] When the stacked multi-layer pallet 8 is transported to the right position, the clamping mechanism 5 clamps the second-layer pallet 8 below. After clamping, the second lifting mechanism 4 drives the clamping mechanism 5 to rise, and the clamping mechanism 5 drives the second-layer pallet 8 and the above pallets 8 to rise, so that the first-layer pallet 8 below is alone on the linear conveyor 2. At this time, the pallet 8 on it is transported to the subsequent loading mechanism through the linear conveyor 2. After transportation, the second lifting mechanism 4 drives the clamping mechanism 5 to descend, so that the existing multi-layer pallet 8 falls back on the linear conveyor 2, and the above actions are repeated to destacker and transport layer by layer.
