Description

Technical Field

[0001] The utility model relates to the field of material stacking devices, in particular to a material stacking and storing device. Background Art

[0002] In the field of warehousing and logistics, stacking materials is an important means of saving space. Pallets are important load-bearing platforms for transporting materials. Stacking the unused pallets can save storage space. The existing method of stacking pallets is mostly to use a hydraulic forklift to stack the pallets from bottom to top. The applicant has found that the existing pallet stacking method has the following shortcomings: on the one hand, the neatness of the pallet stacking cannot be guaranteed, and there is a safety hazard of tipping over if the pallets are stacked too high; on the other hand, since the pallets are stacked at least sequentially from the bottom, a hydraulic forklift needs to be used to continuously lift the pallets when stacking the upper pallets, and when taking pallets from the pallet material pile, they need to be taken sequentially from top to bottom. The hydraulic forklift needs to adjust the height before each operation, which makes the operation complicated and affects the stacking and taking efficiency of the pallets. Utility Model Content

[0008] A material conveying assembly, wherein the material conveying assembly comprises a conveying device, and the conveying device is used to horizontally convey the material to or away from the bottom of the storage cavity.

[0009] Based on the above structure, a method of using the material stacking and storage device is as follows:

[0010] During feeding, the conveying device stops conveying after conveying the material to the bottom of the storage chamber, and the lifting component moves to the limit claw corresponding to the material on the conveying device, and the limit claw is moved into the bracket by the first driving device, and then the lifting component moves upward until the material is separated from the conveying device; during re-feeding, after the conveying device conveys the material to the bottom of the storage chamber, the lifting component moves to the material on the limit claw and is stacked on the material at the bottom, and the first driving device drives the limit claw to move out of the bracket, and the lifting component descends again until the limit claw corresponds to the material on the conveying device, and then drives the limit claw into the bracket of the material at the bottom, and finally the lifting component moves upward until the material is separated from the conveying device. It should be noted that during feeding, the distance between the bottom of the material on the limit claw and the conveying device is greater than the height of the feeding material, so as to facilitate feeding. The limit stopper can prevent the material stacked in the storage chamber from tipping over.

[0011] When discharging, the conveying device stops moving, the lifting assembly moves downward to the bottom of the material and places it on the conveying device, the first driving device drives the limiting claw to move out of the bottom bracket, the lifting assembly moves upward to a preset height corresponding to the amount of material discharged, the first driving device drives the limiting claw to enter the bracket, and the lifting assembly moves upward again to separate the material on the limiting claw from the material below; finally, the material below the limiting claw is transported out through the conveying device or the external transfer device; when the material in the storage chamber needs to be transferred out at one time, the lifting assembly places the material on the conveying device, and the limiting claw moves out of the bracket, and then directly moves all the materials on the conveying device out.
