Description

Technical Field

[0001] The utility model relates to the field of polyamide spinning production equipment, and particularly relates to an automatic ton bag lifting type pallet changing device.

Background Art

[0002] As the main raw material for polyamide spinning production, most of the chips are transported in ton bags. The daily production capacity of a medium-sized polyamide spinning production workshop can reach 80 tons. To ensure the continuity of production every day, an average of nearly 100 bags of ton bag chips need to be transported in a workshop every day. This process requires a large amount of manpower, forklifts, and flatbed trucks to work together to ensure the timely supply of chips. Currently, the following problems exist:

[0003] 1. Ton bag chips belong to heavy monomers, with a large daily demand in production. A large amount of manpower, forklifts, and trucks are required during transportation, resulting in high production costs; usually, it takes 5 people and 2 vehicles to work simultaneously to load a truck with chips.

[0004] 2. During the transportation of ton bags, manual assistance in hanging straps, forklift operation, and manual pallet changing have led to work-related injury accidents, serious safety hazards, and low efficiency.

[0005] 3. During transportation, it is very easy for manual labor / forklifts to break the ton bags, resulting in air leakage in the ton bags, causing the chip particles to contact oxygen and be oxidized, resulting in downgrading or scrapping of the chips.

[0006] 4. Some manufacturers have made automated improvements, such as using a clamping method to greatly improve the automated transportation and stacking of ton bags to a certain extent. However, this method has requirements for ton bags. The clamping force on both sides needs to be large enough to successfully clamp and lift the ton bags, but too much force is likely to damage the ton bags and cause air leakage.

[0007] To solve the above problems, reduce safety hazards, ensure the quality of ton bag chips, and improve operation efficiency, an automatic ton bag lifting type pallet changing device has been developed.

[0036] In another embodiment of the present invention, the working process of the present invention is as follows:

[0037] Refer to Figure 2, after the bulk bags are taken out of the warehouse, the bulk bag A carried on the pallet 200 moves to the pallet-changing station above the lifter 11 through the conveyor line 100 and then the conveyor line 100 stops running. The lifter 11 drives the top teeth 12 to rise. The top teeth 12 first pass through the roller gap of the conveyor line 100 and then through the hole 201 in the middle of the pallet 200 (a hole 201 corresponding to the top teeth 12 is provided in the middle of the pallet 200), lifting the bulk bag A on the pallet 200, so that the bottom of the bulk bag is separated from the pallet 200 (refer to Figure 2 in S1 - S2).

[0038] Immediately afterwards, the fork tooth lifting structure 3 starts to work. The fork teeth 31 on both sides of the pallet-changing station are inserted from the bottom of the side of the bulk bag, and then the bulk bag is lifted by about 1.5 meters. At the same time, the lower lifter 11 descends and disengages from the pallet 200. After the lifter 11 descends in place, the conveyor line 100 runs and the pallet 200 is automatically conveyed forward to the pallet recycling station. When the pallet 200 leaves the pallet-changing station, the second bulk bag B carried on the pallet enters. The fork tooth lifting structure 3 lowers the lifted bulk bag A above and directly places it on the top of the bulk bag B. When the bulk bag A is placed on the top of the bulk bag B, the clamping structure 4 starts to work. The clamp 42 starts to clamp the bulk bag A, and then the fork teeth 31 are withdrawn from the bottom of the bulk bag A. The clamp 42 slowly releases, allowing the upper bulk bag A to be stacked on the top of the bulk bag B, completing a stacking operation (refer to Figure 2 in S3 - S6).

[0039] When the stacking action is completed, the lifter 11 drives the top teeth 12 to rise, causing the bottom of the bulk bag B to disengage from the pallet 200. Then, the side fork teeth 31 are inserted from the bottom of the bulk bag B, and the two bulk bags are lifted upward simultaneously. At this time, the bottom pallet 200 of the bulk bag B is conveyed to the pallet recycling station through the conveyor line 100. At the same time, when the pallet 200 leaves the pallet-changing station, the wooden frame 300 is conveyed to the pallet-changing station. After the wooden frame 300 arrives at the pallet-changing station, the fork tooth lifting structure 3 controls the fork teeth 31 to move downward and the lifter 11 moves upward. When the top teeth 12 of the lifter 11 reach the bottom of the bulk bag B, the fork teeth 31 are withdrawn from both sides, and then the lifter 11 descends to the initial position, placing the two stacked bulk bags on the wooden frame 300. (Refer to Figure 2 in S7 - S12) Subsequently, the wooden frame 300 is conveyed to the shipping port through the conveyor line and unloaded by a forklift to complete the loading.

[0040] In summary, the advantages of the present utility model are as follows:

[0041] 1. Through the form of bottom jacking and side clamping, the present utility model can effectively reduce the side pressure of the bulk bags, reduce the risk of air leakage, and ensure the stability of quality.

[0043] 3. Automated operation avoids the problem of downgrading the quality of the sliced products caused by air leakage of the ton bags during manual operation.

[0044] 4. It can be continuously produced, thus ensuring the stability of the quality of the backend products; it also improves the efficiency of on-site operations, reduces the buffer area of the workshop, and is conducive to on-site material control.
