Description

Material lifting and conveying system

Technical Field

The invention relates to a material lifting and conveying system for a fine network connection, and belongs to the field of automatic mechanical equipment.

Background

And (4) fine connection, namely a mechanical connection equipment system between the spinning frame and the bobbin winder. The working efficiency of the spinning frame is limited, and more than 2 spinning frames, even 3-5 spinning frames are generally needed to correspond to and meet the working efficiency of one bobbin winder. In the early production process of a yarn mill, spun yarn spools are collected mainly by workers and then are transported to a corresponding winder area for winding, and strict registration and management are needed in the process so as to prevent corresponding transportation errors from affecting production. The specification of the spun yarn product relates to parameters such as color, count and the like, and the spun yarn products with the same color and different counts are difficult to identify by naked eyes, so in order to prevent errors, strict numbering is needed, circulation, storage and transportation records are made, and a large amount of manpower and material resources are consumed.

In order to improve the production efficiency and reduce the risk of material disorder in the storage and transportation process, special 'fine connection' equipment is generated, and 'fine connection' is established between a plurality of spinning machines and a plurality of bobbin winders.

At present, some solutions for fine network connection exist in the market, for example, a fine network connection conveying system with chinese patent publication No. CN104846492A or chinese patent publication No. CN204608276U, which utilizes the relatively mature AGV smart car technology at present, sets a plurality of AGV cars between a spinning frame working group and a bobbin winder working group, and utilizes a wireless remote control device and a wireless scheduling device to perform overall control on the AGV cars. However, the AGV intelligent transportation system mainly depends on the development of the AGV control technology, the use and maintenance cost is high, and the AGV moves on the ground, occupies the ground space of a workshop, and can influence the daily maintenance work of workers in the workshop. The AGV trolley also needs to be charged and maintained, and the use requirement can be met only through excessive configuration.

There are also a fine-winding union bobbin yarn conveying device with chinese patent publication No. CN207987402U, a fine-winding union bobbin yarn conveying device with chinese patent publication No. CN108301079A and a conveying method thereof, a fine-winding union bobbin yarn conveying system with chinese patent publication No. CN110386506A and a conveying method thereof, a fine-winding union bobbin yarn conveying system with chinese patent publication No. CN110396738A and a conveying method thereof, and a conveying interface device of fine-winding union bobbin yarn and bobbin with chinese patent publication No. CN108560088A and a conveying method thereof, and a fine-winding union pallet operating device with chinese patent publication No. CN201236242Y, which disclose a series of fine-winding union solution schemes, but introduce more the whole connection mode and system operation mode, and do not relate to the specific conveying mechanism scheme.

The conveying interface device of the fine winding bobbin yarn and bobbin with the Chinese patent publication number of CN108560088A and the conveying method thereof are also disclosed, and the conveying interface device of the fine winding bobbin yarn and bobbin with the Chinese patent publication number of CN207877969U discloses the specific details of some fine winding devices, but the conveying efficiency is low by adopting a relatively complex single spindle conveying mode, the single spindle output interval of a spinning frame is very short, and the high-frequency switching channel of the fine winding device is needed to meet the operation of the whole system.

In order to meet the production requirements of yarn factory workshops, further research on the fine network connection between the spinning machine and the winding machine is necessary to break through the fine network connection technology, particularly a group-to-group connection fine network connection system.

In the whole fine network system, the design of a track conveying system, the design of a material lifting and conveying system and the design of a complete machine control system are included, and the application is mainly researched aiming at the lifting and conveying system of the materials.

The two ends of the track-changing guide rod 216 are fixed on the component fixing plate 214, the track-changing sliding block 217 is sleeved on the track-changing guide rod, the track-changing sliding block 217 is fixed on the track mounting plate 213, and the track-changing switching process can be smoother and more stable by arranging the track-changing guide rod 216 and the track-changing sliding block 217.

The orbital transfer drive element may also employ a drive system such as a linear electric cylinder, a linkage mechanism, or the like.

In the system, the lifting frame is not provided with a walking driving mechanism, but friction wheels are arranged on the lifting rail at intervals, and the lifting frame is driven by the friction wheels, so that the lifting frame can move on the lifting rail. Specifically, reference may be made to the prior art, such as a friction drive type lifting conveyor with chinese patent publication No. CN100482554C, a hybrid drive type conveyor with chinese patent publication No. CN100467361C, and a double friction drive device with chinese patent publication No. CN 201980324U.
