[0027] The terms used in the present invention are those general terms currently widely used in the art in consideration of the functions of the present invention, but these terms may vary according to the intention of a person of ordinary skill in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in this case, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as a general description based on the meaning of the terms and the present invention.

[0028] Reference Figure 1-4 This embodiment provides a simple turnover box depalletizing and stacking mechanism, including:

[0029] The main body 1 includes a frame 1-1, which is arranged in the middle section of the roller conveyor belt and is used for performing depalletizing and stacking operations on the turnover boxes conveyed thereto;

[0030] The lifting part 2 includes an upper lifting mechanism 2-1, which is arranged at the inner bottom of the frame 1-1 and drives the turnover box on the roller conveyor belt to rise through the lifting action;

[0031] The clamping part 3 is provided with two groups, and the two groups of clamping parts 3 are symmetrically arranged on the inner side of the frame 1-1, and are used to clamp the turnover box on the top of the upper mechanism 2-1 through a clamping action to facilitate stacking or disassembly.

[0032] A base frame 1-2 is installed at the inner bottom of the frame 1-1, and leveling seats 1-3 are installed at the four corners of the bottom of the frame 1-1. The stability of the frame 1-1 can be adjusted by the leveling seats 1-3.

[0033] The lifting mechanism 2-1 includes a base 2-1a, a lifting platform 2-1b is arranged on the base 2-1a, and a lifting cylinder 2-1c for controlling the lifting / lowering action of the lifting platform 2-1b is installed at the bottom of the base 2-1a;

[0034] Specifically, three groups of brackets 2-1e are fixed on the upper surface of the lifting platform 2-1b. The three groups of brackets 2-1e are respectively located at the gaps between two adjacent rollers in the roller conveyor belt. The roller conveyor belt passes through the frame 1-1. The turnover box is conveyed along with the roller conveyor belt. When it is conveyed to the position of the lifting platform 2-1b, the lifting cylinder 2-1c operates to drive the lifting platform 2-1b to rise. When the lifting platform 2-1b rises, it drives the three groups of brackets 2-1e to rise. The three groups of brackets 2-1e pass through the gaps between the rollers and lift up the turnover boxes on its surface.

[0035] A guide member 2-1d is arranged between the base 2-1a and the lifting platform 2-1b. The guide member 2-1d includes a guide column fixed to the bottom of the lifting platform 2-1b. The bottom end of the guide column passes through the base 2-1a. A guide hole is arranged on the surface of the base 2-1a corresponding to the position of the guide column, which can play a guiding role and ensure the stability of the lifting / lowering action.

[0036] The clamping part 3 includes a base plate 3-1, which is mounted on the base 2-1a, and a clamping plate 3-2 is arranged on the base plate 3-1, and the clamping plate 3-2 is driven by a clamping cylinder 3-3.

[0037] A limiting mechanism 3-4 is installed on the base plate 3-1 and arranged between the clamping plate 3-2. The limiting mechanism 3-4 includes a guide rail 3-4a and a guide groove 3-4b. When the height of the turnover box to be clamped is located within the clamping area of ​​the clamping plate 3-2, the two groups of clamping cylinders 3-3 operate to make the two clamping plates 3-2 move relative to each other, thereby clamping the turnover box in the area.

[0038] Working process: S1: The lifting cylinder 2-1c operates to drive the lifting platform 2-1b to rise. When the lifting platform 2-1b rises, it drives the three sets of brackets 2-1e to rise. The three sets of brackets 2-1e pass through the gaps between the rollers to lift the turnover boxes on their surfaces until the turnover boxes rise to the working area of ​​the clamping part 3. At this time, the two sets of clamping cylinders 3-3 operate to make the two clamping plates 3-2 move relative to each other, and clamp the turnover boxes in the area (this turnover box is one layer);

[0039] S2: After the first layer of turnover boxes is clamped, the lifting cylinder 2-1c retracts and drives the three sets of brackets 2-1e to reset. After resetting, the roller conveyor will transport the turnover boxes again (this turnover box is the second layer). At this point, the lifting cylinder 2-1c drives the three sets of brackets 2-1e to drive the second layer of turnover boxes to rise until the second layer of turnover boxes is located at the bottom of the first layer of turnover boxes and supports them. At this time, the two sets of clamping cylinders 3-3 retract and drive the two clamping plates 3-2 to release the clamping of the first layer of turnover boxes, and the first layer of turnover boxes is stacked on top of the second layer of turnover boxes;

[0040] S3: The lifting cylinder 2-1c continues to rise, driving the second layer of turnover boxes and the first layer of turnover boxes to rise synchronously, until the second layer of turnover boxes rises to the working area of ​​the clamping part 3, and the two groups of clamping cylinders 3-3 drive the two clamping plates 3-2 to clamp the second layer of turnover boxes;

[0041] At this time, the lifting cylinder 2-1c drives the three groups of brackets 2-1e to reset, and repeats the S1-S3 actions until all turnover boxes are stacked. The depalletizing steps are opposite to the stacking steps. This structure simplifies the turnover box depalletizing structure, has high safety, easy maintenance, and reduces costs.

[0042] As an optional embodiment:

[0043] See the instruction manual Figure 5 In one embodiment provided in the present application, the lifting part 2 also includes a baffle mechanism 2-2, which is located on one side of the upper lifting mechanism 2-1 and is used to block the turnover box on the roller conveyor belt in the working area of ​​the upper lifting mechanism 2-1.

[0044] Specifically, the baffle mechanism 2-2 includes a fixed seat 2-2a, the bottom of which is mounted on the base 2-1a through a fixed rod 2-2b, and an L-shaped baffle 2-2c is arranged on the fixed seat 2-2a, and a baffle cylinder 2-2d for controlling the rise / fall of the L-shaped baffle 2-2c is installed at the bottom of the fixed seat 2-2a.

[0045] When the turnover box is transported to the position of the lifting platform 2-1b along the roller conveyor belt, the baffle cylinder 2-2d rises, driving the L-shaped baffle 2-2c to rise, passing through the gap between the rollers, blocking the turnover box transported here, and providing positioning for the operation of the upper mechanism 2-1, ensuring that the turnover box is in the working area of ​​the lifting platform 2-1b. This structure does not require monitoring equipment control, and can control the rising interval of the baffle cylinder 2-2d to match the time it takes for the turnover box to pass here. It has the characteristics of fast response and low failure rate.

[0046] Specifically, a guide rod is fixed to the bottom of the L-shaped baffle 2-2c, and the bottom of the guide rod passes through the fixed seat 2-2a, which can play a stabilizing role when the L-shaped baffle 2-2c is raised / lowered.

[0047] As an optional embodiment:

[0048] See the instruction manual Figure 6 A positioning mechanism 3-5 is provided on the clamping side of the clamping plate 3-2, and the positioning mechanism 3-5 is used for the reinforcing ribs on the outside of the turnover box.

[0049] The positioning mechanism 3-5 includes a clamping strip 3-5a, on which a U-shaped groove 3-5b is symmetrically provided, and a positioning groove 3-5c is provided on one side of the clamping strip 3-5a at the position corresponding to the U-shaped groove 3-5b, and a sliding groove 3-5d is symmetrically provided on both sides of the positioning groove 3-5c on one side of the clamping strip 3-5a.

[0050] The turnover box is usually a rectangular plastic part. The upper edge of the rectangle will be turned outward to form a buckle groove that can be carried by hand. In order to increase the strength of the outward buckle groove, reinforcing ribs will be provided on the outside of the turnover box. The reinforcing ribs connect the outward buckle groove and the turnover box. However, the reinforcing ribs are also plastic strips, which are easily squeezed during clamping, causing the reinforcing ribs to break and be damaged. Therefore, a positioning groove 3-5c is provided on the outside of the clamping strip 3-5a. When clamping, the clamping strip 3-5a can fit perfectly on the outside of the turnover box without squeezing the reinforcing ribs on the outside of the turnover box, thereby avoiding the problem of damaging the turnover box.

[0051] A collapse member is movably provided in the positioning groove 3-5c, and the collapse member includes a movable block 3-5e, a connecting rod 3-5f is fixed at one end of the movable block 3-5e, one end of the connecting rod 3-5f passes through the positioning groove 3-5c and extends into the C-shaped groove 3-5b, a spring 3-5g is sleeved on the outside of the connecting rod 3-5f located in the positioning groove 3-5c, and a trapezoidal block 3-5h is fixed at the end of the connecting rod 3-5f located in the C-shaped groove 3-5b, when the clamping strip 3-5a is clamped, the reinforcing rib abuts against the movable block 3-5e, and the movable block 3-5e slides backward in the positioning groove 3-5c to provide a position for the reinforcing rib to enter the positioning groove 3-5c, and when the movable block 3-5e slides, the trapezoidal block 3-5h is displaced through the connecting rod 3-5f, and the spring 3-5g is compressed at the same time;

[0052] A slide plate for clamping the outer reinforcing ribs of the turnover box is slidably arranged in the slide groove 3-5d, and the slide plate includes a pair of clamping plates 3-5i slidably arranged in the slide groove 3-5d and a linkage plate 3-5j symmetrically arranged in the U-shaped groove 3-5b. A linkage rod 3-5k is rotatably connected between one end of the linkage plate 3-5j and the pair of clamping plates 3-5i. The middle section of the linkage rod 3-5k is rotatably connected in the U-shaped groove 3-5b through a support rod 3-5l, and the other end of the connecting rod 3-5f is elastically connected to the U-shaped groove 3-5b.

[0053] One end of the linkage plate 3-5j that fits into the inclined surface of the trapezoidal block 3-5h is also an inclined surface structure. When the trapezoidal block 3-5h moves backward, the two linkage plates 3-5j are driven to move relative to each other through the resistance of the inclined surfaces. When the linkage plate 3-5j moves outward, the two clamping plates 3-5i are driven to move relative to each other through the linkage rod 3-5k, clamping the reinforcement ribs of the turnover box, which can play a role in clamping the turnover box. Stability, avoid the problem of damage caused by the outward buckle groove during clamping.

[0054] Finally, it should be pointed out that the methods and devices described in detail above are only embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
