Description

A heavy-duty adaptive stacker Technical Field

[0001] This utility model relates to the field of stacking machines, and in particular to a heavy-duty adaptive stacking machine. Background Technology

[0002] Existing pallet handling machines generally have the following shortcomings when transporting heavy pallets, which are often heavy and vary in size:

[0003] 1. Poor adaptability: It cannot automatically adjust the fork spacing to adapt to pallets of different sizes, requiring manual intervention and resulting in low efficiency;

[0004] 2. Complex structure: Traditional equipment relies on multiple power units for adjustment, which is costly and difficult to maintain;

[0005] 3. Insufficient stacking compatibility: For pallet groups with mixed stacking methods (such as large bottom pallets and small top pallets), it is difficult to stably separate and transport them. Summary of the Invention

[0006] To address the aforementioned issues, this invention provides a heavy-duty adaptive stacking machine capable of processing stacks of pallets of different sizes and weights. It utilizes a servo motor to drive sliding forks on both sides, thereby saving components and reducing manufacturing and maintenance costs.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] As shown in Figure 1, the stacking machine mainly consists of a main platform 1 and a heavy-duty conveyor 2. The heavy-duty conveyor 2 is installed on the main platform 1 and can hold a whole stack of pallets 4.

[0021] Preferably, a protruding limiting marker 3 is set on the ground in front of the main unit 1 (designated as front, the opposite side as rear, and the other two sides as left and right sides), which can remind the staff to maintain a certain distance from the main unit, thereby ensuring their personal safety.

[0022] As shown in Figure 2, the main unit 1 includes a base 11, with two lower side frames 16 on the left and right sides of the base 11, and a higher rear frame 18 at the rear end. A horizontally extending front guide rail 12 is mounted on the front of both side frames 16, and a horizontally extending rear guide rail 13 is mounted on the front of the rear frame 18. Two sliding forks 15 capable of sliding left and right are mounted on both the front and rear guide rails 12 and 13, and both sliding forks 15 are connected to a servo transmission mechanism 14. Therefore, both sliding forks 15 can slide left and right along the front and rear guide rails 12 and 13 under the action of the servo transmission mechanism 14.

[0023] The servo drive mechanism 14 includes a servo motor and a drive belt extending to the left and right. The rear ends of the two sliding forks 15 are connected to the upper and lower sides of the drive belt, respectively, so that they can move away from or towards each other under the operation of the servo motor.

[0024] Preferably, the servo drive is mounted on the rear frame 18.

[0025] Preferably, a protective net 17 is installed above at least one side frame 16, which can be used to protect the stacker from the side.

[0026] In addition, multiple horizontal fork plates 19 are installed on the opposite surfaces of the two sliding fork rods 15, and each fork plate 19 can be used to hold the pallet 4 together.

[0027] As shown in Figure 3, the heavy-duty conveyor 2 includes a heavy-duty hydraulic lift 21 and a conveying mechanism 22. The heavy-duty hydraulic lift 21 is mounted on the base 11 of the main unit 1, and the conveying mechanism 22 is mounted on top of the heavy-duty hydraulic lift 21 and located below it between two sliding forks 15. The conveying mechanism 22 can be raised and lowered as the heavy-duty hydraulic lift 21 operates.

[0028] In addition, multiple conveyor rollers 23 extending forward and backward are installed side by side on the conveyor mechanism 22. Each conveyor roller 23 is arranged left and right and can receive pallets 4 delivered by the conveyor line or forklift.

[0029] When this stacker is in use, the process mainly includes the following steps:

[0030] S1: Use a conveyor line or forklift to transport a stack of pallets 4 onto the conveying mechanism 22 of the heavy conveyor 2. The size and weight of the stack of pallets 4 may not be consistent, and they may not be arranged according to size and weight.

[0031] S2: The operation of the heavy-duty hydraulic lift 21 raises the conveyor mechanism 22 and the stacked pallet 4 until the bottom pallet 4 is below the forks 19 of the two sliding forks 15, and the second pallet 4 from the bottom is above the forks 19 of the two sliding forks 15.

[0032] S3: The servo transmission mechanism 14 operates to make the two sliding forks 15 slide closer to each other until each fork plate 19 extends under the second pallet 4 from the bottom. Then each fork plate 19 can hold the pallet 4 and the entire stack of pallets 4 on it, leaving only the bottom pallet 4 on the conveying mechanism 22.

[0033] S4: The operation of the heavy-duty hydraulic lift 21 causes the conveying mechanism 22 and the bottom pallet 4 to descend. Then the conveying mechanism 22 operates to transport the bottom pallet 4 out. At this time, the second pallet 4 from the bottom becomes the bottom pallet 4. The entire stack of pallets 4 is held by two sliding forks 15.

[0034] S5: The operation of the heavy-duty hydraulic lift 21 causes the conveying mechanism 22 to rise to contact the lowest pallet 4 at this time. Then the servo transmission mechanism 14 operates to make the two sliding forks 15 slide away from each other, so that the entire stack of pallets 4 falls onto the conveying mechanism 22.

[0035] S6: The operation of the heavy-duty hydraulic lift 21 causes the conveyor mechanism 22 and the stacked pallet 4 to descend until the bottom pallet 4 is below the forks 19 of the two sliding forks 15, while the second pallet 4 from the bottom is above the forks 19 of the two sliding forks 15.

[0036] S7: Repeat steps S3 to S6 until all pallets 4 have been transported out.

[0037] The heavy-duty adaptive stacking machine of this utility model has the following advantages:

[0038] 1. High adaptability: It can handle stacks of pallets of different sizes and weights;

[0039] 2. Simplified structure: The sliding forks on both sides are driven by a servo motor, which reduces the number of parts compared to the traditional solution;

[0040] 3. Cost reduction: Both total manufacturing and maintenance costs are lower than traditional solutions.

[0041] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
