Intelligent robot arm automatic doffing device

Abstract

The invention discloses an intelligent robot arm automatic doffing device which comprises a doffing air frame, an air frame transmission component and a bobbin conveying part and the like. An original synchronous belt speed reduction transmission structure is omitted for the air frame transmission component, a servo motor is adopted to directly drive a speed reducer through a coupler, power is transmitted to a lead screw pair through chain wheel transmission, a lifting pull rod moves in a left-right mode axially and drives a lifting connecting rod and a lifting swing rod of an inversely V-shaped lifting link mechanism, a holding beam is obliged to drive a yarn holding device to move up and down in the vertical plane, and thus lifting motion of the yarn holding device and the holding beam is finished. According to the intelligent robot arm automatic doffing device, during pull and insertion of a bobbin, intermediate transition movement links of air frame transmission are omitted, doffing time is reduced, the intelligent robot arm automatic doffing device has higher production efficiency and higher movement accuracy, and bobbin pull and insertion accuracy is ensured.

Description

technical field [0001] The invention belongs to the field of spinning frames, and in particular relates to an improvement in the structure of an automatic doffing device of an intelligent robot arm. Background technique [0002] The ring spinning frame is a process that plays a key role in the cotton spinning production process, and it is the concentration point of the spinning mill's labor-intensive and labor-intensive problems. Due to the high degree of automation of the spinning frame equipped with a collective doffing device, the operation can be completed automatically during the entire spinning process, which can shorten the doffing time, save the finishing work and finishing equipment of the empty bobbins, and greatly reduce the cost of bobbins. The quality has been improved, and the entire doffing process can be completed almost without people, thus greatly improving labor productivity. At present, most domestic textile enterprises still use manual doffing, and each...

Problems solved by technology

Since the power of this transmission mode is decelerated by the servo motor through the synchronous belt transmission, and then transmitted to the screw nut through the reducer, it is required to maintain a strict action space and installation position during work, which affects the transmission efficiency and increases the accumulation. error

This structure not only increases the intermediate transition link, but also adds an unreliable factor, increases the complexity of the doffing device structure, increases the manufacturing cost of the doffing device, and increases the labor intensity of the operator
