Problems solved by technology

The top pneumatic clamping collective doffing method can only be used for spinning frames with collective doffing devices. If the original old-fashioned spinning frame is modified, the cost is expensive and the installation size of the machine is not enough
Can only purchase new collective doffing spinning frames and rebuild workshops

Embodiment Construction

[0022] The present invention will be described in more detail below in conjunction with the accompanying drawings.

[0023] Preliminary preparation and positioning of the automatic vertical doffing machine of the present invention: as figure 1 As shown, when a spinning frame needs to doff, the doffer trolley carrier 1 is pushed to the head or tail of the spinning frame, and is docked with the spinning frame track. Insert the power cord plug 36, start the start button, the doffing machine is driven by the first motor 2 to the synchronous belt 3, the wheel shaft 19 drives the side wheel 4 of the trolley carrier 1, and the first motor moves forward along the spinning frame track. The forward movement of 2 will rotate on the gear 19 to drive the screw mandrel and slide block on the empty tube support 15 to act on the empty tube support 15 empty tube loading device 16, the tube driving device 18, and the S-shaped slideway 17 moves forward to the spun yarn Above the spinning frame ...

Abstract

The invention relates to an automatic vertical doffer, and belongs to the technical field of spinning equipment of spinning frames. The equipment comprises a trolley carrier, a programmable logic control (PLC) system, a vertical mechanical arm, a parallel mechanical arm, transmission mechanisms of first, second and third motors, a tube loosening device, a tube grabbing device, a tube pulling device, a tube conveying device, an empty tube loading device and a tube inserting device; therefore, vertical pulling of a full package and insertion of an empty tube are automatically carried out. The automatic vertical doffer can complete a doffing procedure instead of manual work, does not contact yarns, cannot damage a spindle blade, has a simple and reliable structure, high doffing and tube inserting speeds and high automation degree, can serve a plurality of spinning frames, effectively reduces the labor intensity of workers and improves the work efficiency of manufacturers.

Description

technical field [0001] The invention belongs to the field of textile equipment, and in particular relates to an automatic vertical doffing and tube insertion device. Background technique [0002] The currently used doffing methods mainly include disc-type pawl doffers and top pneumatic clamping collective doffers. During the doffing process of the disc-type pawl doffing machine, the disc-type pawl on the doffing machine will be forcibly detached from the spindle bar of the spinning frame from the oblique side of the yarn bobbin. The disadvantage of this type of doffing device is the long-term action It will cause the spindle rod to bend and deform. Because the disc pawl will contact the yarn on the bobbin, the yarn will be damaged and broken, causing unnecessary waste and work. Therefore, the manufacturers of doffing in this way are not very acceptable. The top pneumatic clamping collective doffing method can only be used for spinning frames with collective doffing device...
