Description

Automatically vertical doffer

Technical field

The invention belongs to the Weaving device field, be specifically related to a kind of automation and vertically doff and Intubaction device.

Background technology

The mode of using at present of doffing mainly contains modes such as the pneumatic clipping collective of disc type ratchet doffer and top doffer.Disc type ratchet doffer is in the process of doffing, and the disc type ratchet on the doffer will be separated the fine spining machine spindle blade by force from the oblique side of yarn tube, and the shortcoming of this doffing device is that long-term action can cause spindle blade flexural deformation.Because the disc type ratchet can contact the yarn on the spool, cause yarn breakage, broken string to cause unnecessary waste and work.So each producer of doffing of this mode not too accepts.The pneumatic clipping collective in the top mode of doffing can only be to having the fine spining machine of integral cosine doffing device, if transform original old-fashioned fine spining machine, it involves great expense, and the board installation dimension is not enough.Can only purchase new collective's doffing spinning machine and transform plant.

Summary of the invention

In order to overcome the deficiency of above-mentioned prior art, the objective of the invention is to be to provide a kind of brand-new automation vertically to unload the device of pipe and intubate.Easy to use need are pushed into the fine spining machine headstock or the tailstock with the automatically vertical doffer of the present invention, and with spinning frame track to docking.Insert power-line plug, start start button, can accomplish automatically and unload pipe and intubate work, have that speed is fast, good stability, do not contact the characteristics of yarn.To the damage of spindle blade and yarn, improve the automatic continuous production level of manufacturer when having overcome present tube drawing and intubate.Reduce working strength of workers simultaneously, reduced the recruitment cost and recruitment pressure of producer.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is done more detailed explanation.

Automatically vertical doffer early-stage preparations of the present invention and location: as shown in Figure 1, when certain fine spining machine need doff, this doffer dolly carrier 1 was pushed into the fine spining machine headstock or the tailstock, and with spinning frame track to docking.Insert power-line plug 36; Start start button; Doffer can be through first motor 2 is transmitted in synchronously with 3, axletree 19 drives dolly carriers 1 side wheel 4, rotate in gear 19 along spinning frame track to the preceding guild of proal while first motor 2 drives screw mandrel, slide block on the blank pipe supports 15 and acts on blank pipe support 15 blank pipes and put device 16, tube pulling transmission device 18; S shape slideway 17 moves forward to fine spining machine spindle blade top, and system 6 makes dolly carrier 1 align with fine spining machine spindle blade position with alignment sensor 7 by PLC control.When dolly carrier 1 travelled forward, the fine spining machine spindle blade can be stirred spool and be inserted in spindle blade, accomplishes intubate work synchronously.

As shown in Figure 2; When dolly carrier 1 aligns with fine spining machine spindle blade position; Second motor 8 be transmitted in parallel mechanical arm 9, on screw mandrel 27, slide block 28, support 10, U-shaped fork 11, refer to clamp 12 and do synchronous ahead running; Accurately insert spindle blades and junctions, spool bottom by U-shaped fork 11, accomplish the sled pine, lift the plumber and do, refer to clamp 12 completion clamp work simultaneously.

As shown in Figure 2, PLC control this moment system 6, the communications cable instruct the 3rd motor 13 be transmitted in perpendicular robotic arm 14, on screw mandrel 26, slide block 29 drive parallel mechanical arm 9 up completion and lift the plumber and do.

As shown in Figure 2, at this moment instruct through PLC control system 6, the communications cable second motor 8 be transmitted in parallel mechanical arm 9, on screw mandrel 27, slide block 28, support 10, U-shaped fork 11, refer to clamp 12 and do synchronous retracting motion, accomplish the fortune plumber and do.Yarn is unloaded in yarn retaining plate 24 completion that midway can run at retraction.Collection yarn road 40 scissors, 41 devices that when the full spool free-falling, are installed in car body can be cut off the tail yarn of connection, fall into collection yarn bag 42.

As shown in Figure 2, PLC control system 6, the communications cable instruct the 3rd motor 13 be transmitted in perpendicular robotic arm 14, on screw mandrel 26, slide block 29 drive this group action of parallel mechanical arm 9 descending completion.Automatically vertical doffing device is taked branch workshop section once only to accomplish a plurality of full spools to doff.Through PLC control system 6 and alignment sensor 7, the dolly carrier is moved to next station carry out repetitive operation then, until the end of doffing of full machine.

Shown in Figure 6 like Fig. 3 Fig. 4 Fig. 5, be that perpendicular robotic arm, parallel mechanical arm are accomplished the work sketch map that pine is managed, grabs pipe, tube drawing, fortune pipe, pipe discharging device.

As shown in Figure 1; Finish PLC control system 6, the communications cable and instruct 2 counter-rotatings of first motor to be transmitted in side wheel 4 dolly carrier 1 is returned when full machine doffs, can drive screw mandrel, slide block on the blank pipe support 15 this moment and act on blank pipe support 15 blank pipes and put device 16, tube pulling transmission device 18, S shape slideway 17 and retract to dolly carrier 1 inside.This device mainly avoids blank pipe slideway 17 and fine spining machine spindle blade to collide.

As shown in Figure 7; When the travelling forward of first motor, 2 transmission dolly carriers 1; Can be transmitted in coil axes 33 driven rotary drums 31 and do rotation forward; Make folding and unfolding coil 5 emit power line 35 can drive dolly carrier 1 when 2 counter-rotatings of first motor motion backward, can be transmitted in coil axes 33 driven rotary drums 31 simultaneously and do rotation backward, make folding and unfolding coil 5 regain power line 35.

All work more than accomplishing, doffer instructs 2 counter-rotatings of first motor to be transmitted in side wheel 4 through PLC control system 6, the communications cable and dolly carrier 1 is returned, get back to starting point, takes off this task of doffer end by the workman and is prepared as next doffing of spinning frame.
