Description

Technical Field

[0001] The utility model relates to processing equipment, in particular to a conveying device capable of realizing material transfer. Background Art

[0002] Current conveying devices generally convey continuously. Sometimes, due to the mismatch in processing speed of the terminal processing station of the conveying device, materials accumulate on the processing station and the conveying device must be stopped. The materials on the conveying device are generally difficult to transfer outward.

[0003] In specific applications, for example, a pallet stacking machine is used to stack materials (usually pallets), and after stacking to a certain height or quantity, the material pile is transferred. In order to meet production needs, the pallet stacking machine will use multiple conveying mechanisms to transport materials at the same time. However, since the time required for material transfer is usually difficult to match the conveying speed of the conveying mechanism, in order to avoid the situation where some materials on the material stacking mechanism are already full, while the corresponding conveying mechanism continues to transport the material backward, the current common method is to shut down the corresponding conveying mechanism when the material stacking mechanism is full of materials, or to control the amount of materials transported by a single conveying mechanism each time. However, these methods make it difficult to give full play to the advantages of simultaneous transportation of multiple conveying mechanisms, and frequent starts and stops can easily cause equipment damage. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a conveying device capable of realizing material transfer, which can not only continuously convey materials, but also transfer materials between different conveying mechanisms or external workstations as needed.
