Description

Automatic bobbin replacing device for spinning

Technical Field

The invention relates to the technical field of spinning, in particular to an automatic bobbin replacing device for spinning.

Background

In market application, the automatic winder is suitable for spinning varieties with high requirements on yarn quality due to multiple functions, but the energy consumption of the winder is high, the price of the winder is high, and the automatic winder is not a small burden for a yarn factory. The existing domestic common bobbin winder has the advantages of low energy consumption, applicable function and low price, but has poor automation degree and more labor. In automation, an important function is automatic bobbin changing, when the yarn is wound, standby simple yarn is ready and enters the bobbin changing, and the automatic bobbin winder needs to adopt machinery and a motor to drive the bobbin changing so as to ensure that the bobbin keeps vertical upward in the movement process, but the structure is complex and the price is high.

The prior Chinese patent CN110642096A discloses a bobbin-changing mechanism for a bobbin winder, which solves the problems of the prior ordinary bobbin winder that the bobbin can only be manually changed by workers and the bobbin-changing position is at the bottom and the bobbin-changing can only be stood down to change, which not only has higher labor intensity and relatively lower efficiency, but also discloses a bobbin-changing mechanism for a bobbin winder, wherein the bobbin yarn is vertically loaded on a mounting rod at the upper side of a turntable by workers, a power device drives the turntable to rotate through a main shaft, the turntable drives a bobbin yarn picking rod and a slide block which penetrate through a supporting seat to slide along a track, and because the distance between the mounting through hole and the top end of the track when the mounting through hole moves to the top end on the turntable is equal to the distance between the mounting through hole and the bottom end of the track when the mounting through hole is at the bottom end and the relative position is consistent, the problems of the ordinary bobbin winder that the bobbin-changing machine can only be stoo, however, the bobbin is still on the machine after bobbin changing, the bobbin changing process is not timely separated from the bobbin winder to follow rotation, winding wires are scattered, effective bobbin changing cannot be achieved, meanwhile manual stooping collection is still needed, a large number of drums need to be lifted and replaced manually in the collecting process, walking is not facilitated, the physical requirement on operators is too high, and long-time labor is easy to cause complications such as lumbar muscle strain.

In summary, there is a need to develop a bobbin capable of automatic replacement, which changes the original manual bobbin replacement method to allow the bobbin carried by the operator to be replaced in large quantities, meanwhile, the empty bobbin storage disc is repeatedly used, so that the bobbin automatic bobbin replacing device for spinning, which reduces the storage space to improve the storage capacity and the storage density and reduces the complexity of manual operation and the weariness of repeated operation, is achieved, the problems that in the prior art, bobbins are still on a machine after being replaced, the bobbins are not timely separated from a winding machine to rotate along with the bobbin replacing machine, the winding is scattered, and effective bobbin replacement cannot be realized are solved, meanwhile, the manual stooping collection is still needed, a large number of rollers are needed to be lifted and replaced during the manual collection process, the walking is inconvenient, and the requirement on the physical strength of an operator is too high, and the complication such as lumbar muscle strain is easily caused by long-time working.
