Description

Technical Field

[0001] The utility model relates to the technical field of logistics manufacturing, and particularly relates to a mother-child stacking machine. Background Art

[0002] In recent years, with the rapid development of industrial intelligent manufacturing, many manufacturing enterprises are facing the challenges of cost control and product upgrading. Therefore, the innovation of production processes and equipment in the manufacturing industry is also imperative. In modern industry, automation in the production process has become a prominent theme, and the automation level of all industries is getting higher and higher, especially in the field of warehouse logistics transportation. In this field, pallets are essential items, and the efficient, fast, and accurate recycling of pallets can not only reduce production costs, improve production efficiency, optimize and improve the working environment of the factory area, but also realize the transformation and upgrading of the "intelligent manufacturing" industry. For common mother-child pallets, since raw material suppliers may provide various sizes and specifications of sub-pallets for handling and storing materials, when they need to be placed on a three-dimensional shelf of a unified specification, these sub-pallets of different sizes need to be placed on a mother-pallet of a unified specification, and then the mother-pallet, sub-pallet, and goods are placed on the three-dimensional shelf. This is the usage method of mother-child pallets.

[0003] After the goods transported by the transportation equipment are removed and placed on the top of the sub-pallet for handling, due to the heavy weight of the goods, the common method is to use a forklift to lift the sub-pallet and the goods. The forklift drives the sub-pallet and the goods to move and places them on the top of the corresponding mother-pallet. Using this method also requires other facilities to protect the sub-pallet and the goods to prevent the phenomenon of the goods falling and being damaged during the stacking process, resulting in waste of resources, and the stacking efficiency and handling efficiency are low.

The counterweight mechanism 16 is set to ensure that the second chain 8 is always in a vertical state, so that the lifting fork mechanism 5 can move up and down more smoothly and reliably, and prevent large shaking when lifting the sub-pallet. The sub-pallet and the goods are lifted synchronously by two lifting fork mechanisms, and the lifting is stable and reliable, which effectively prevents the goods from falling, and the stacking effect is good, the stacking efficiency is high, and the handling efficiency is improved.
